  1. Critical management issues for the Uranium Mill Tailings Remedial Action (UMTRA) Project

    International Nuclear Information System (INIS)

    Themelis, J.G.; Krishnan, K.R.

    1985-01-01

    The Uranium Mill Tailings Radiation Control Act of 1978 (PL95-604) authorized the Secretary of Energy to enter into cooperative agreements with certain states and Indian Tribes to clean up 24 inactive uranium mill tailing sites and associated vicinity properties. The Uranium Mill Tailings Remedial Action (UMTRA) Project includes the three Federal agencies (EPA, DOE, and NRC), eleven state, Indian Tribes, and at least four major contractors. The UMTRA Project extends over a period of ten years. The standards for the Project require a design life of 1000 years with a minimum performance period of 200 years. This paper discusses the critical management issues in dealing with the UMTRA Project and identifies the development of solutions for many of those issues. The highlights to date are promulgation of EPA standards, continued support from Congress and participating states and Indian Tribes, significant leadership shown at all levels, establishment of credibility with the public, and continued motivation of the team. The challenge for tomorrow is making certain NRC will license the sites and maintaining the high level of coordination exhibited to date to assure Project completion on schedule

    Full Text Available Background: Disasters cause almost 100 thousand deaths and affect 200 million people every year. Operators working in disaster zones reported problems in importing medications, in particular pain killers and narcotics, in areas of disasters. The importance of ensuring access to painkillers, including major analgesics, is pinpointed by the World Health Organization which through its “Access to Controlled Medications Programme” provides normative guidance, policy analysis and training of healthcare workers on this issue. Nevertheless the little evidence available on the assessment and treatment of pain in disasters suggests that the management of pain in disaster zones may be affected by several factors mainly due to the availability of drugs, the skills of health personnel and cultural issues. Aim:The main aims of this project are: evaluating whether pain is correctly assessed and treated in disaster zones, assessing which are the main limitations to its treatment and producing suggestions and reccomandations to improve its treatment. Materials & Methods: In order to achieve our aims we will adopt a combined approach made by: A systematic review of the evidence will be conducted in the scientific databases Medline and Scopus. A review of grey literature concerning the issue on the Web pages of international organizations and NGOs working in the field of humanitarian aid. A survey among healthcare workers who took part to the international humanitarian actions. A survey among expert of the humanitarian field not necessary involved in projects on the field e.g. lawyer expert in international law, international organizations representatives working in the headquarters etc. A technical table with European experts in the field of pain treatment and/or disaster reaponse.

    2003-01-01

    Science, new technology, patient care, dental reimbursement and government regulations all affect today's dental practitioners. To find out more about how such challenges may affect current private practitioners, the American Dental Association conducted the 2000 Membership Needs and Opinions Survey. A questionnaire was sent to 6,310 ADA members in January 2000 with follow-up mailings in February, March and April 2000. Data collection was completed in July 2000. The survey included questions on critical professional issues, and on perceptions of the ADA and ADA priorities. A total of 3,558 completed surveys were received for an adjusted response rate of 59.5 percent. Members rated the identified issues' level of importance to them. The top three issues included "maintaining my ability to recommend the treatment option I feel is most appropriate for my patients," "receiving fair reimbursement for the dental services I provide," and "protecting myself, my staff and my patients from communicable diseases." New dentists found other items to be more significant to them compared with members overall. Although ADA members as a whole had similar views on critical issues facing dentistry and ADA priorities, there were significant differences regarding some issues. New dentists were far more concerned about securing funds for their practice and paying off debt than were all ADA members. Minority dentists expressed greater levels of concern about certain issues than did all ADA members. When planning and implementing ADA activities, the Association should continue to take into account members' relative rankings of professional issues and note issues of special interest to selected membership subgroups.

  9. Handbook of critical issues in goal programming

    CERN Document Server

    Romero, C

    1991-01-01

    Goal Programming (GP) is perhaps the oldest and most widely used approach within the Multiple Criteria Decision Making (MCDM) paradigm. GP combines the logic of optimisation in mathematical programming with the decision maker's desire to satisfy several goals. The primary purpose of this book is to identify the critical issues in GP and to demonstrate different procedures capable of avoiding or mitigating the inherent pitfalls associated with these issues. The outcome of a search of the literature shows many instances where GP models produced misleading or even erroneous results simply because

  10. A critical Social Work project

    Directory of Open Access Journals (Sweden)

    2006-04-01

    Full Text Available Contemporary social transformations, operated by the neoliberal program under the command of financial capital, bring new challenges to the group of citizens and men and women who live by the sale of their labor power. Social workers, individually and collectively, are not separate from this reality. The profession was characterized by its confrontation with these challenges and its questioning and analysis of its role in society, in its attempt to assume more critical profiles and commitments to the interests of workers and the subaltern sectors. An example of this is the “Reconceptualization Movement” and the later attempt to define na “Alternative Social Service” concerned with the meaning of its practice, with the process of critical knowledge, with a criticism of capitalism and its situations of social injustice. The current challenges include overcoming earlier weaknesses, collectively constructing an ethicalpolitical professional project that can competently and committedly confront, at the heart of progressive social forces, the conditions in which workers live (with or without employment as well as other subaltern populations.

  11. Nuclear waste management in Canada : critical issues, critical perspectives

    Durant, D.; Fuji Johnson, G.

    2009-01-01

    As oil reserves decline and the environment takes centre stage in public policy discussions, the merits and dangers of nuclear power and nuclear waste management continue to be debated. Canada is intent on building more reactors to increase energy production without destroying the planet, but it and other nuclear energy-producing countries face not only technical problems but also social and ethical issues. This book provides a critical antidote to the favourable position of government and industry. The contributors build their case by exploring key issues and developments. What do frequently used terms such as safety, risk, and acceptability really mean? How and why did the public consultation process in Canada fail to address ethical and social issues? What is the significance and potential of a public consultation process that involves diverse interests, epistemologies, and actors, including Aboriginal peoples? And how do we ensure that our frameworks for discussion are inclusive and ethical? This timely collection defuses the uncertainty, ambiguity, and ignorance that surrounds nuclear energy. It will appeal to academics, students, and stakeholders in public policy or environmental studies who want to think critically and more broadly about how we approach energy generation and waste management.

  12. Critical issues in NASA information systems

    Science.gov (United States)

    1987-01-01

    The National Aeronautics and Space Administration has developed a globally-distributed complex of earth resources data bases since LANDSAT 1 was launched in 1972. NASA envisages considerable growth in the number, extent, and complexity of such data bases, due to the improvements expected in its remote sensing data rates, and the increasingly multidisciplinary nature of its scientific investigations. Work already has begun on information systems to support multidisciplinary research activities based on data acquired by the space station complex and other space-based and terrestrial sources. In response to a request from NASA's former Associate Administrator for Space Science and Applications, the National Research Council convened a committee in June 1985 to identify the critical issues involving information systems support to space science and applications. The committee has suggested that OSSA address four major information systems issues; centralization of management functions, interoperability of user involvement in the planning and implementation of its programs, and technology.

  13. ITER - TVPS remote handling critical design issues

    International Nuclear Information System (INIS)

    1990-09-01

    This report describes critical design issues concerning remote maintenance of the ITER Torus Vacuum Pumping System (TVPS). The key issues under investigation are the regeneration/isolation valve seal and seal mechanism replacement; impact of inert gas operation; impact of remote handling (RH) on the building configuration and RH equipment requirements. Seal exchange concepts are developed and their impact on the valve design identified. Concerns regarding the design and operation of RH equipment in an inert gas atmosphere are also explored. The report compares preliminary RH equipment options, pumping equipment maintenance frequency and their impact on the building design, and makes recommendations where a conflict exists between pumping equipment and the building layout.

    The high-average power capability of FELs has been much advertised but little realized. In this paper we provide a critical analysis of the technological and economic issues associated with high-average power FEL operation from the UV to near IR. The project of IR FEL for the Siberian Center of photochemical researches is described. The distinguished features of this project are the use of the race-track microtron-recuperator and the {open_quotes}electron output of radiation{close_quotes}. The building for the machine is under reconstruction now. About half of hardware has been manufactured. The assembly of installation began.

    Plasmas regimes with improved core energy confinement properties, i.e. with internal transport barriers (ITB), provide a possible route towards simultaneous high fusion performance and continuous tokamak reactor operation in a non-inductive current drive state. High core confinement regimes should be made compatible with a dominant fraction of the plasma current self-generated (pressure-driven) by the bootstrap effect while operating at high normalized pressure and moderate current. Furthermore, ITB regimes with 'non-stiff' plasma core pressure break the link observed in standard inductive operation between fusion performances and plasma pressure at the edge, thus offering a new degree of freedom in the tokamak operational space. Prospects and critical issues for using plasmas with enhanced thermal core insulation as a basis for steady tokamak reactor operation are reviewed in the light of the encouraging experimental and modelling results obtained recently (typically in the last two years). An extensive set of data from experiments carried out worldwide has been gathered on ITB regimes covering a wide range of parameters (q-profile, T{sub i}/T{sub e}, gradient length, shaping, normalized toroidal Larmor radius, collisionality, Mach number, etc). In the light of the progress made recently, the following critical physics issues relevant to the extrapolation of ITB regimes to next-step experiments, such as ITER, are addressed: 1. conditions for ITB formation and existence of a power threshold,; 2. ITB sustainment at T{sub i} {approx} T{sub e}, with low toroidal torque injection, low central particle fuelling but at high density and low impurity concentration,; 3. control of confinement for sustaining wide ITBs that encompass a large volume at high {beta}{sub N},; 4. real time profile control (q and pressure) with high bootstrap current and large fraction of alpha-heating and; 5. compatibility of core with edge transport barriers or with external core

    A wide range of optics issues for energy recovery linac (ERL)-based projects are illustrated through the presentation of ongoing projects covering both light sources, at Cornell and Daresbury and high energy and nuclear physics accelerators at the Brookhaven National Laboratory. This presented range of projects demonstrates how the different designs teams see the challenges of studying and solving optics issues for their particular project's ERLs, with studies appropriate to the stage of maturity of the project. Finally, as an illustration of the complexity and detail behind a single aspect of ERL optics design we present an overview of the highly important generic topic of longitudinal phase space evolution in ERLs

    Full Text Available This article aimed to identify those issues that were present in global technological innovation projects carried out by Brazilian multinational companies and which performance criterions these undertakings met. We investigated 36 global technological innovation projects from Brazilian multinational enterprises through a web-survey. Findings show that these companies went beyond the traditional iron triangle to evaluate their technological efforts and considered additional performance dimensions such as customer satisfaction, business results, and preparation for the future. Results also show high degree of presence for issues emerging from the industry, moderate degree of presence for issues emerging from both the project and R&D activities, and low degree of presence for issues emerging from the headquarters, the subsidiaries, and the external environment. Further research is needed to find out if and how these issues influenced the performance of the global technological innovation projects studied.DOI:10.5585/gep.v3i1.72

  18. Critical Issues in Modelling Lymph Node Physiology

    Full Text Available In this study, we discuss critical issues in modelling the structure and function of lymph nodes (LNs, with emphasis on how LN physiology is related to its multi-scale structural organization. In addition to macroscopic domains such as B-cell follicles and the T cell zone, there are vascular networks which play a key role in the delivery of information to the inner parts of the LN, i.e., the conduit and blood microvascular networks. We propose object-oriented computational algorithms to model the 3D geometry of the fibroblastic reticular cell (FRC network and the microvasculature. Assuming that a conduit cylinder is densely packed with collagen fibers, the computational flow study predicted that the diffusion should be a dominating process in mass transport than convective flow. The geometry models are used to analyze the lymph flow properties through the conduit network in unperturbed- and damaged states of the LN. The analysis predicts that elimination of up to 60%–90% of edges is required to stop the lymph flux. This result suggests a high degree of functional robustness of the network.

    1992-06-01

    Recently there has been much interest in a new polymer nematic dispersion technology, often called as NCAP, PDLC, PNLC, LCPC, etc., since projection displays using this technology have been shown to produce much brighter display images than projectors using conventional twisted nematic (TN) lightvalves. For commercializing projection displays based on this polymer nematic dispersion technology, the new materials must not only meet various electro- optic requirements, e.g., operational voltage, `off-state'' scattering angle, voltage holding ratio and hysteresis, but must also be stable over the lifetime of the product. This paper reports recent progress in the development of NCAP based projection displays and discusses some of the key commercialization issues.

    As the power generation capacity of LWRs in Japan increased, the establishment and development of nuclear fuel cycle have become the important subject. Conforming to the safety research project of the nation, the Japan Atomic Energy Research Institute has advanced the project of constructing a new research facility, that is, Nuclear Fuel Cycle Engineering Research Facility (NUCEF). In this facility, it is planned to carry out the research on criticality safety, upgraded reprocessing techniques, and the treatment and disposal of transuranium element wastes. In this paper, the subjects of criticality safety research and the research carried out with a criticality safety experiment facility which is expected to be installed in the NUCEF are briefly reported. The experimental data obtained from the criticality safety handbooks and published literatures in foreign countries are short of the data on the mixture of low enriched uranium and plutonium which is treated in the reprocessing of spent fuel from LWRs. The acquisition of the criticality data for various forms of fuel, the elucidation of the scenario of criticality accidents, and the soundness of the confinement system for gaseous fission products and plutonium are the main subjects. The Static Criticality Safety Facility, Transient Criticality Safety Facility and pulse column system are the main facilities. (Kako, I.)

    Full text: Experience after the Chernobyl accident has shown that remediation strategies need to consider a wide range of different issues to ensure the long-term sustainability of radioactively contaminated areas. The STRATEGY project (Sustainable Restoration And Long-Term Management Of Contaminated Rural, Urban And Industrial Ecosystems (www.strategy-ec.org.uk) had the overall objective of establishing a holistic decision framework for the selection of optimal remediation strategies for long-term sustainable management of contaminated areas in Western Europe. The project carried out a critical evaluation of a series of countermeasures and waste disposal options including a consideration of their technical feasibility and practicality and whether they (i) incur considerable direct or side-effect costs; (ii) have significant environmental side effects; and (iii) are acceptable to society. A main output was a comprehensive, documented evaluation of more than 100 countermeasures (in the form of standardized templates) that would be relevant for off-site nuclear emergency management in the mid to long term. Stakeholder participation is an important mechanism to explore these additional benefits or disadvantages to the use of countermeasures, and is an essential step in developing a decision framework which avoids problems previously experienced in emergency management. Close liaison with the FARMING stakeholder network facilitated evaluation of countermeasure templates for rural ecosystems. Stakeholder opinion suggested that some countermeasures were as likely to be rejected an socio-ethical grounds as technical and economic grounds. Rejection of specific countermeasures would be expected to show site, context and national differences. Suitable approaches for successfully communicating with a wide range of stakeholders were explored. The way in which countermeasure evaluation and selection is carried out is particularly relevant for ethical evaluation of remediation

    Construction of infrastructure project is different from buildings. The main difference is term of project site where infrastructure project need to command a long stretch while building mostly confine to a limited area. As such factors that are critical to infrastructure project may not be that significant to building project and vice versa. Flood mitigation can be classified under infrastructure projects under which their developments are planned by the government with the specific objective to reduce or avoid the negative effects of flood to the environment and livelihood. One of the indicators in project success is delay. The impact of project delay in construction industry is significant that it decelerates the projects implementation, specifically the government projects. This study attempted to identify and compare the success factors between infrastructure and building projects, as such comparison rarely found in the current literature. A model of flood mitigation projects' success factors was developed by merging the experts' views and reports from the existing literature. The experts' views were obtained from the responses to open-ended questions on the required fundamentals to achieve successful completion of flood mitigation projects. An affinity analysis was applied to these responses to develop the model. The developed model was then compared to the established success factors found in building project, extracted from the previous studies to identify the similarities and differences between the two models. This study would assist the government and construction players to become more effective in constructing successful flood mitigation projects for the future practice in a flood-prone country like Malaysia.

    Full Text Available The purpose of this study is to determine the critical success factors (CSF of IT projects in Pa-kistan. The identified factors cannot only be functional to exact type IT projects but also to all types of IT projects, their success directly affects the achievement of whole organization. The proposed study of this paper has determined 15 factors influencing the most on the success of IT projects through multiple regression analysis. The survey has disclosed that many CSFs were found related to IT projects but these 15 factors are also the backbone of IT projects. The re-search results obtained clearly indicated that the Leadership Qualities played a significant role in obtaining Top Management support in order to access to resources however, the Leadership Qualities did not play any role on the trained and capable Project Team Members. Besides, it is undoubtedly defined effective communication of the project was established to be influential on the conclusion and contributing factor towards the Success of IT projects in Pakistan. Top Man-agement Support as a whole was not found to play a key role in the IT Project Success.

    In order to properly manage the risk of a nuclear criticality accident, it is important to establish the conditions for which such an accident becomes possible for any activity involving fissile material. Only when this information is known is it possible to establish the likelihood of actually achieving such conditions. It is therefore important that criticality safety analysts have confidence in the accuracy of their calculations. Confidence in analytical results can only be gained through comparison of those results with experimental data. The Criticality Safety Benchmark Evaluation Project (CSBEP) was initiated in October of 1992 by the US Department of Energy. The project was managed through the Idaho National Engineering and Environmental Laboratory (INEEL), but involved nationally known criticality safety experts from Los Alamos National Laboratory, Lawrence Livermore National Laboratory, Savannah River Technology Center, Oak Ridge National Laboratory and the Y-12 Plant, Hanford, Argonne National Laboratory, and the Rocky Flats Plant. An International Criticality Safety Data Exchange component was added to the project during 1994 and the project became what is currently known as the International Criticality Safety Benchmark Evaluation Project (ICSBEP). Representatives from the United Kingdom, France, Japan, the Russian Federation, Hungary, Kazakhstan, Korea, Slovenia, Yugoslavia, Spain, and Israel are now participating on the project In December of 1994, the ICSBEP became an official activity of the Organization for Economic Cooperation and Development - Nuclear Energy Agency's (OECD-NEA) Nuclear Science Committee. The United States currently remains the lead country, providing most of the administrative support. The purpose of the ICSBEP is to: (1) identify and evaluate a comprehensive set of critical benchmark data; (2) verify the data, to the extent possible, by reviewing original and subsequently revised documentation, and by talking with the

  7. Capitals, assets, and resources: some critical issues.

    This paper explores the potential of Bourdieu's approach to capital as a way of understanding class dynamics in contemporary capitalism. Recent rethinking of class analysis has sought to move beyond what Rosemary Crompton (1998) calls the 'employment aggregate approach', one which involves categorizing people into class groups according to whether they have certain attributes (e.g. occupations). Instead, recent contributions by Pierre Bourdieu, Erik Wright, Aage Sorensen, and Charles Tilly have concentrated on understanding the mechanisms that produce class inequalities. Concepts such as assets, capitals and resources (CARs) are often used to explain how class inequalities are produced, but there remain ambiguities and differences in how such terms are understood. This paper identifies problems faced both by game theoretical Marxism and by the rational choice approach of Goldthorpe in developing an adequate approach to CARs. It then turns to critically consider how elements of Bourdieu's approach, where his concept of capital is related to those of habitus and field, might overcome these weaknesses. Our rendering of his arguments leads us to conclude that our understanding of CARs might be enriched by considering how capital is distinctive not in terms of distinct relations of exploitation, but through its potential to accumulate and to be converted to other resources. This focus, we suggest, sidesteps otherwise intractable problems in CAR based approaches.

    1991-01-01

    Transportation planning for a repository at Yucca Mountain is complicated because of uncertainty about the modes and numbers of nuclear waste shipments and because of uncertainty about the routes which will be used. There could be as many as 76,000 truck shipments, or as few as 1,060 dedicated train shipments, during repository operations. The site lacks rail access. Three rail access options currently under study range in length from 120 miles to more than 400 miles. The site is more than 100 miles from the Interstate highway system. The UNLV Transportation Research Center has evaluated three rail and four highway routes using a broad range of impact measures. This preliminary evaluation found that the routing options differ significantly regarding resident and non-resident populations, environmentally sensitive areas, accident rates, and other factors. Crosscutting issues include impacts on Nevada Indian tribes, potential conflicts with US Air Force operations, and future population growth in southern Nevada. Considerable additional analysis will be required prior to environmental impact statement scoping

    The Veterans Health Administration (VHA), of the U.S. Department of Veteran Affairs has instituted a medical record (EMR) that includes electronic documentation of all narrative components of the medical record. To support clinicians using the system, multiple efforts have been instituted to ease the creation of narrative reports. Although electronic documentation is easier to read and improves access to information, it also may create new and additional hazards for users. This study is the first step in a series of studies to evaluate the issues surrounding the creation and use of electronic documentation. Eighty-eight providers across multiple clinical roles were interviewed in 10 primary care sites in the VA system. Interviews were tape-recorded, transcribed and qualitatively analyzed for themes. In addition, specific questions were asked about perceived harm due to electronic documentation practices. Five themes relating to difficulties with electronic documentation were identified: 1) information overload; 2) hidden information; 3) lack of trust; 4) communication; 5) decision-making. Three providers reported that they knew of an incident where current documentation practices had caused patient harm and over 75% of respondents reported significant mis-trust of the system.

  14. Nuclear criticality project plan for the Hanford Site tank farms

    Energy Technology Data Exchange (ETDEWEB)

    Bratzel, D.R., Westinghouse Hanford

    1996-08-06

    The mission of this project is to provide a defensible technical basis report in support of the Final Safety Analysis Report (FSAR). This technical basis report will also be used to resolve technical issues associated with the nuclear criticality safety issue. The strategy presented in this project plan includes an integrated programmatic and organizational approach. The scope of this project plan includes the provision of a criticality technical basis supporting document (CTBSD) to support the FSAR as well as for resolution of the nuclear criticality safety issue. Specifically, the CTBSD provides the requisite technical analysis to support the FSAR hazard and accident analysis as well as for the determination of the required FSAR limits and controls. The scope of The CTBSD will provide a baseline for understanding waste partitioning and distribution phenomena and mechanistics for current operational activities inclusive of single-shell tanks, double-shell tanks, double-contained receiver tanks, and miscellaneous underground storage tanks.. Although the FSAR does not include future operational activities, the waste partitioning and distribution phenomena and mechanistics work scope identified in this project plan provide a sound technical basis as a point of departure to support independent safety analyses for future activities. The CTBSD also provides the technical basis for resolution of the technical issues associated with the nuclear criticality safety issue. In addition to the CTBSD, additional documentation will be required to fully resolve U.S. Department of Energy-Headquarters administrative and programmatic issues. The strategy and activities defined in this project plan provide a CTBSD for the FSAR and for accelerated resolution of the safety issue in FY 1996. On April 30, 1992, a plant review committee reviewed the Final Safety Analysis Reports for the single-shell, double-shell, and aging waste tanks in light of the conclusions of the inadequate waste

  15. Critical safety issues in the design of fusion machines

    International Nuclear Information System (INIS)

    Kramer, W.

    1991-01-01

    In the course of developing fusion machines both general safety considerations and safety assessments for the various components and systems of actual machines increase in number and become more and more coherent. This is particularly true for the NET/ITER projects where safety analysis plays an increasing role for the design of the machine. Since in a D/T tokamak the radiological hazards will be dominant basic radiological safety objectives are discussed. Critical safety issues as identified in particular by the NET/ITER community are reviewed. Subsequently, issues of major concern are considered both for normal operation and for conceivable accidents. The following accidents are considered to be crucial: Loss of cooling in plasma facing components, loss of vacuum, tritium system failure, and magnet system failure. To mitigate accident consequences a confinement concept based on passive features and multiple barriers including detritiation and filtering has to be applied. The reactor building as final barrier needs special attention to cope with both internal and external hazards. (orig.)

  19. Business Intelligence Issues for Sustainability Projects

    Directory of Open Access Journals (Sweden)

    Mihaela Muntean

    2018-01-01

    Full Text Available Business intelligence (BI is an umbrella term for strategies, technologies, and information systems used by the companies to extract from large and various data, according to the value chain, relevant knowledge to support a wide range of operational, tactical, and strategic business decisions. Sustainability, as an integrated part of the corporate business, implies the integration of the new approach at all levels: business model, performance management system, business intelligence project, and data model. Both business intelligence issues presented in this paper represent the contribution of the author in modeling data for supporting further BI approaches in corporate sustainability initiatives. Multi-dimensional modeling has been used to ground the proposals and to introduce the key performance indicators. The démarche is strengthened with implementation aspects and reporting examples. More than ever, in the Big Data era, bringing together business intelligence methods and tools with corporate sustainability is recommended.

  20. Proposed REDD+ project for the Sundarbans: Legal and institutional issues

    Directory of Open Access Journals (Sweden)

    Saiful Karim

    2013-07-01

    Full Text Available Sundarbans, a Ramsar and World Heritage site, is the largest single block of tidal halophytic mangrove forest in the world covering parts of Bangladesh and India. Natural mangroves were very common along the entire coast of Bangladesh. However, all other natural mangrove forests, including the Chakaria Sundarbans with 21,000 hectares of mangrove, have been cleared for shrimp cultivation. Against this backdrop, the Forest Department of Bangladesh has developed project design documents for a project called ‘Collaborative REDD+ Improved Forest Management (IFM Sundarbans Project’ (CRISP to save the only remaining natural mangrove forest of the country. This project, involving conservation of 412,000 ha of natural mangrove forests, is expected to generate, over a 30-year period, a total emissions reduction of about 6.4 million tons of CO2. However, the successful implementation of this project involves a number of critical legal and institutional issues. It may involve complex legal issues such as forest ownership, forest use rights, rights of local people and carbon rights. It may also involve institutional reforms. Ensuring good governance of the proposed project is very vital considering the failure of the Asian Development Bank (ADB funded and Bangladesh Forest Department managed ‘Sundarbans Biodiversity Conservation Project’. Considering this previous experience, this paper suggests that a comprehensive legal and institutional review and reform is needed for the successful implementation of the proposed CRISP project. This paper argues that without ensuring local people’s rights and their participation, no project can be successful in the Sundarbans. Moreover, corruption of local and international officials may be a serious hurdle in the successful implementation of the project.

    Full Text Available ABSTRACT The objective of this paper is to analyze critical situations experienced by women entrepreneurs and understand how they have overcome such situations. The study contributes to the understanding of the issues related to the activities of women entrepreneurs and shows that the use of the critical incident technique is relevant to the development of research in the field of entrepreneurship. The data were collected using a specific form with 115 women participating in the study. The analysis of critical incidents showed that in addition to the practical issues regarding the management of their business, emotions are interconnected with their business development. Unlike international studies in the field, the critical incidents experienced by Brazilian women entrepreneurs overlap with personal aspects. The women involved in this study face emotional difficulties, but are also motivated by strong feelings of determination to overcome their problems.

  2. Validation issues for depletion and criticality analysis in burnup credit

    Parks, C.V.; Broadhead, B.L.; Dehart, M.D.; Gauld, I.C.

    2001-01-01

    This paper reviews validation issues associated with implementation of burnup credit in transport, dry storage, and disposal. The issues discussed are ones that have been identified by one or more constituents of the United States technical community (national laboratories, licensees, and regulators) that have been exploring the use of burnup credit. There is not necessarily agreement on the importance of the various issues, which sometimes is what creates the issue. The broad issues relate to the paucity of available experimental data (radiochemical assays and critical experiments) covering the full range and characteristics of spent nuclear fuel in away-from-reactor systems. The paper will also introduce recent efforts initiated at Oak Ridge National Laboratory (ORNL) to provide technical information that can help better assess the value of different experiments. The focus of the paper is on experience with validation issues related to use of burnup credit for transport and dry storage applications. (author)

  3. A critical view on singular therapeutic projects

    Directory of Open Access Journals (Sweden)

    Fernando Sfair Kinker

    2016-04-01

    Full Text Available This article discusses the issue of unique therapeutic projects within the mental health services built in the Brazilian psychiatric reform process. Starting from the concepts that have gained strength in both the psychiatric reform as in the collective health, this study proposes that current notions of the therapeutic project still are influenced by biological, psychological or social paradigms that simplify the complexity of the experience suffered by the subjects. Despite therapeutic projects are an essential achievement for the qualification of mental health care, it is still necessary to produce an epistemological rupture in the relationship with mental suffering so that they can achieve the greatest potential for transformation. Therefore, the article suggests that the practice of therapeutic projects should hold discussions with the reality of users life of and their relationships in the territories of existence, to transform the relations of power and knowledge that reproduce the subjects annulment. Thus, it is possible to dialogue with the complexity of the mental suffering experience, producing changes in the scenes that produce it.

  6. Dryland ecohydrology and climate change: critical issues and technical advances

    Directory of Open Access Journals (Sweden)

    L. Wang

    2012-08-01

    Full Text Available Drylands cover about 40% of the terrestrial land surface and account for approximately 40% of global net primary productivity. Water is fundamental to the biophysical processes that sustain ecosystem function and food production, particularly in drylands where a tight coupling exists between ecosystem productivity, surface energy balance, biogeochemical cycles, and water resource availability. Currently, drylands support at least 2 billion people and comprise both natural and managed ecosystems. In this synthesis, we identify some current critical issues in the understanding of dryland systems and discuss how arid and semiarid environments are responding to the changes in climate and land use. The issues range from societal aspects such as rapid population growth, the resulting food and water security, and development issues, to natural aspects such as ecohydrological consequences of bush encroachment and the causes of desertification. To improve current understanding and inform upon the needed research efforts to address these critical issues, we identify some recent technical advances in terms of monitoring dryland water dynamics, water budget and vegetation water use, with a focus on the use of stable isotopes and remote sensing. These technological advances provide new tools that assist in addressing critical issues in dryland ecohydrology under climate change.

    Hines, Dennis O.

    2012-01-01

    In Fiscal Year 2011 Dryden Flight Research Center (DFRC) implemented a new project management system called Critical Chain Project Management (CCPM). Recent NASA audits have found that the Dryden workforce is strained under increasing project demand and that multi-tasking has been carried to a whole new level at Dryden. It is very common to have an individual work on 10 different projects during a single pay period. Employee surveys taken at Dryden have identified work/life balance as the number one issue concerning employees. Further feedback from the employees indicated that project planning is the area needing the most improvement. In addition, employees have been encouraged to become more innovative, improve job skills, and seek ways to improve overall job efficiency. In order to deal with these challenges, DFRC management decided to adopt the CCPM system that is specifically designed to operate in a resource constrained multi-project environment. This paper will discuss in detail the rationale behind the selection of CCPM and the goals that will be achieved through this implementation. The paper will show how DFRC is tailoring the CCPM system to the flight research environment as well as laying out the implementation strategy. Results of the ongoing implementation will be discussed as well as change management challenges and organizational cultural changes. Finally this paper will present some recommendations on how this system could be used by selected NASA projects or centers.

  11. Critical issues for the early introduction of commercial fusion reactor

    International Nuclear Information System (INIS)

    Okano, Kunihiko; Yoshida, Tomoaki

    1996-01-01

    Critical issues for the realization of commercial fusion reactor are discussed on the basis of a prediction of power source composition in the next century. The key issue is rather a relaxation in the construction site condition than a competitive cost in comparison with the nuclear fission power plant. It seems a logical conclusion that the competitor of the fusion plant in the cost will be a future CCT (Clean Coal Technology) and/or LNG plant loaded with a CO 2 recovery system. (author)

    Evans, Robert S.; Husser, Dewayne L.; Jensen, Russell R.; Kerr, John M.

    1994-07-01

    Particle-Bed Reactors (PBRs) potentially offer performance advantages for nuclear thermal propulsion, including very high power densities, thrust-to-weight ratios, and specific impulses. A key factor in achieving all of these is the development of a very-high-temperature fuel. The critical issues for all such PBR fuels are uranium loading, thermomechanical and thermochemical stability, compatibility with contacting materials, fission product retention, manufacturability, and operational tolerance for particle failures. Each issue is discussed with respect to its importance to PBR operation, its status among current fuels, and additional development needs. Mixed-carbide-based fuels are recommended for further development to support high-performance PBRs.

    1998-09-01

    The Critical Issues Forum (CIF) funded by the US Department of Energy is a collaborative effort between the Science Education Team of Los Alamos National Laboratory (LANL) and New Mexico high schools to improve science education throughout the state of New Mexico as well as nationally. By creating an education relationship between the LANL with its unique scientific resources and New Mexico high schools, students and teachers participate in programs that increase not only their science content knowledge but also their critical thinking and problem-solving skills. The CIF program focuses on current, globally oriented topics crucial to the security of not only the US but to that of all nations. The CIF is an academic-year program that involves both teachers and students in the process of seeking solutions for real world concerns. Built around issues tied to LANL`s mission, participating students and teachers are asked to critically investigate and examine the interactions among the political, social, economic, and scientific domains while considering diversity issues that include geopolitical entities and cultural and ethnic groupings. Participants are expected to collaborate through telecommunications during the research phase and participate in a culminating multimedia activity, where they produce and deliver recommendations for the current issues being studied. The CIF was evaluated and found to be an effective approach for teacher professional training, especially in the development of skills for critical thinking and questioning. The CIF contributed to students` ability to integrate diverse disciplinary content about science-related topics and supported teachers in facilitating the understanding of their students using the CIF approach. Networking technology in CIF has been used as an information repository, resource delivery mechanism, and communication medium.

    The federal government offers a number of tax incentives to developers of biomass projects. This paper describes each tax benefit, explains what conditions must be met before the benefit is available, and offers practical insights gained from working for over 10 years in the field. Understanding what tax benefits are available is important because the more tax benefits a developer can qualify for in connection with his project, the less expensive the project will be to build and operate and the easier it will be to arrange financing because there will be higher returns in the project for potential investors

  18. Critical issues in the history, philosophy, and sociology of astrobiology.

    Science.gov (United States)

    Dick, Steven J

    2012-10-01

    Fifty years after serious scientific research began in the field of exobiology, and forty years after serious historical research began on the subject of extraterrestrial life, this paper identifies and examines some of the most important issues in the history, philosophy, and sociology of what is today known as astrobiology. As in the philosophy of science in general, and in the philosophies of particular sciences, critical issues in the philosophy and sociology of astrobiology are both stimulated and illuminated by history. Among those issues are (1) epistemological issues such as the status of astrobiology as a science, the problematic nature of evidence and inference, and the limits of science; (2) metaphysical/scientific issues, including the question of defining the fundamental concepts of life, mind, intelligence, and culture in a universal context; the role of contingency and necessity in the origin of these fundamental phenomena; and whether or not the universe is in some sense fine-tuned for life and perhaps biocentric; (3) societal issues such as the theological, ethical, and worldview impacts of the discovery of microbial or intelligent life; and the question of whether the search for extraterrestrial life should be pursued at all, and with what precautions; and (4) issues related to the sociology of scientific knowledge, including the diverse attitudes and assumptions of different scientific communities and different cultures to the problem of life beyond Earth, the public "will to believe," and the formation of the discipline of astrobiology. All these overlapping issues are framed by the concept of cosmic evolution-the 13.7 billion year Master Narrative of the Universe-which may result in a physical, biological, or postbiological universe and determine the long-term destiny of humanity.

  1. Critical issues and experimental examination on sawtooth and disruption physics

    International Nuclear Information System (INIS)

    Itoh, K.; Itoh, S.; Fukuyama, A.; Tsuji, S.

    1992-06-01

    The catastrophic phenomena which are associated with the major disruption and sawtooth contain three key processes: (1) Sudden acceleration of the growth of the helical deformation, (2) Central electron temperature crash, and (3) Rearrangement of the plasma current. Based on the theoretical model that the magnetic stochasticity plays a key role in these processes, the critical issues and possible experimental tests are proposed. Present experimental observations would be sufficient to study the detailed sequences and causes. Though models may not be complete the comparison with experiments improves understandings. (author)

    Public space is endowed with undeniable social relevance, thus becoming a defining element of integration and interaction among its users. Aware of this importance the Universidade Federal da Paraíba (UFPB), linked to the Ministério da Educação e Cultura (MEC), develops the project "UFPB para todos: eliminando barreiras'' (UFPB for all: removing barriers) that aims to conceive an architectural design of an accessible rout to UFPB's campus I, and execute a pilot stretch of this route. This article aims to subsidize the preprojectual phase by understanding the needs of this campus' users, through the concepts of ergonomics and universal design. Was performed out direct observation of the space, and the methods of interviews and observation of user behavior were applied to a group of students with disabilities, through the techniques of assisted walking, photographic and video recording. Based on those, projective guidelines have been defined, which will contribute to the final project's quality, so that this is not a simple application of the rule, but works free of segregating barriers.

    High-level radioactive waste from nuclear fuels processing is stored in underground waste storage tanks located in the tank farms on the Hanford Site. Waste in tank storage contains low concentrations of fissile isotopes, primarily U-235 and Pu-239. The composition and the distribution of the waste components within the storage environment is highly complex and not subject to easy investigation. An important safety concern is the preclusion of a self-sustaining neutron chain reaction, also known as a nuclear criticality. A thorough technical evaluation of processes, phenomena, and conditions is required to make sure that subcriticality will be ensured for both current and future tank operations. Subcriticality limits must be based on considerations of tank processes and take into account all chemical and geometrical phenomena that are occurring in the tanks. The important chemical and physical phenomena are those capable of influencing the mixing of fissile material and neutron absorbers such that the degree of subcriticality could be adversely impacted. This report describes a logical approach to resolving the criticality safety issues in the Hanford waste tanks. The approach uses a structured logic diagram (SLD) to identify the characterization needed to quantify risk. The scope of this section of the report is limited to those branches of logic needed to quantify the risk associated with a criticality event occurring. The process is linked to a conceptual model that depicts key modes of failure which are linked to the SLD. Data that are needed include adequate knowledge of the chemical and geometric form of the materials of interest. This information is used to determine how much energy the waste would release in the various domains of the tank, the toxicity of the region associated with a criticality event, and the probability of the initiating criticality event

    Full Text Available The article presents the latest results of studies about the effect of dissolved oxygen on the efficiency of the ASP flooding project implemented by Salym Petroleum Development N.V.. Pilot project on experimental injection of anionic surfactant solutions, soda and polymer into the reservoir for enhanced oil recovery (ASP project has been implemented since 2016. The stability of one of the components of the ASP polymer is strongly dependent on the presence of iron, stiffness cations and dissolved oxygen in the water. Since the polymer is used for injection at two stages of the project, which are essential and the longest, at the design stage of ASP project a whole complex of polymer protection had been established against negative factors, in particular from the influence of oxygen, which causes not only oxygen corrosion but also irreversible destruction polymer chains. In the paper, studies on the stability of polymer solutions are described, an analysis of viscosity loss with time in the presence of iron and oxygen for polymer solutions is carried out. The choice of chemical deoxygenation method for the control of dissolved oxygen is substantiated. The program of laboratory studies of the ASP project and the analytical instruments used are described. The technological scheme of the ASP process is presented, and recommendations for the implementation of the technology are given.

    The Governor of Nevada was notified in 1983 that the Yucca Mountain site is a potentially acceptable site for a nuclear waste storage site. A series of public hearings held produced nearly 400 comments on issues concerning the site nomination. Areas of primary public concern are the impact of the proposed nuclear site on tourism, transportation, and socioeconomic impact on adjacent communities. Results of recent studies showed no impact of high-level waste transport on tourism in the Las Vegas area and on analysis of data accumulated over the 25 to 30 years that high-level radioactive wastes have been transported on Nevada highways showed that no one has been evacuated from their home as the result of an accident involving radioactive waste. A comparison of the possible effects of construction of a nuclear waste storage facility at the Yucca mountain site with the effects of Nevada Test Site indicate that the impact on communities will be minimal

    2014-02-01

    In recent years, CO2-based technologies have gained considerable interest in the pharmaceutical industry for their potential applications in drug formulation and drug delivery. The exploitation of peculiar properties of gases under supercritical conditions has been studied in the last 20 years with mixed results. Promising drug-delivery technologies, based on supercritical CO2, have mostly failed when facing challenges of industrial scaleability and economical viability. Nevertheless, a 'second generation' of processes, based on CO2 around and below critical point has been developed, possibly offering technology-based solutions to some of the current issues of pharmaceutical development. In this review, we highlight the most recent advancements in this field, with a particular focus on the potential of CO2-based technologies in addressing critical issues in oral delivery, and briefly discuss the future perspectives of dense CO2-assisted processes as enabling technologies in drug delivery.

    2011-11-01

    As a result of recent events, including natural disasters and pandemics, mass critical care planning has become a priority. In general, planning involves limiting the scope of disasters, increasing the supply of medical resources, and allocating scarce resources. Entities at varying levels have articulated ethical frameworks to inform policy development. In spite of this increased focus, children have received limited attention. Children require special attention because of their unique vulnerabilities and needs. In May 2008, the Task Force for Mass Critical Care published guidance on provision of mass critical care to adults. Acknowledging that the critical care needs of children during disasters were unaddressed by this effort, a 17-member Steering Committee, assembled by the Oak Ridge Institute for Science and Education with guidance from members of the American Academy of Pediatrics, convened in April 2009 to determine priority topic areas for pediatric emergency mass critical care recommendations.Steering Committee members established subgroups by topic area and performed literature reviews of MEDLINE and Ovid databases. Draft documents were subsequently developed and revised based on the feedback from the Task Force. The Pediatric Emergency Mass Critical Care Task Force, composed of 36 experts from diverse public health, medical, and disaster response fields, convened in Atlanta, GA, on March 29-30, 2010. This document reflects expert input from the Task Force in addition to the most current medical literature. The Ethics Subcommittee recommends that surge planning seek to provide resources for children in proportion to their percentage of the population or preferably, if data are available, the percentage of those affected by the disaster. Generally, scarce resources should be allocated on the basis of need, benefit, and the conservation of resources. Estimates of need, benefit, and resource utilization may be more subjective or objective. While the

    People with stomas who have either been cured of cancer or are living with cancer have achieved good interrelationships among the three issues of"establishing self-care","dealing with stoma complications", and"accepting stomas", and they are maintaining stable physical and mental states.However, self-care may become difficult due to stoma complications and adverse events caused by chemotherapy and radiation therapy in the cancer treatment period, and in advanced phases of cancer serious stoma complications may occur due to deterioration of general condition and advancing cancer. Therefore, there is a risk that those stable physical and mental states will collapse.In order to deal with this critical state, in the cancer treatment period, stoma skin care is used for handling skin problems around the stoma, and for adverse events such as hand-and-foot syndrome, braces that are easy to operate are chosen from among various types of stoma braces in order to cover impediments.During advanced phases of cancer, care is conducted with the main priority placed on physical stability in order to ensure that the three major complications of stoma varicose veins, stoma prolapse, and parastomal hernia do not worsen and significantly affect general condition and daily life.Stoma outpatient treatment that provides lifelong support for such issues, and the existence of skin- and excretion-care certified nurses who provided highly specialized selfcare support, are extremely important for cancer survivors with stomas.

    Construction industry of Pakistan is creating a number of opportunities in employment as well as plays a role model for economy development of the country. This construction industry has a serious issue of cost overrun in all construction projects especially in construction of highway projects. Cost overrun is a serious and critical issue in construction of highway projects which gives negative impact to construction practitioners because it is not only cross the approved budget but also approved time of the project. The main objective of this study is to find out critical factors causing cost overrun in highway projects of Sindh according to contractors' perspectives. Deep literature review was carried out and a total of 64 factors of cost overrun were identified. To achieve the objective, a questionnaire was designed and distributed among 16 selected respondents who have more than 20 years of experience in construction of highway projects. The results from analysis found that most critical factors of cost overrun in the order of importance include financial and cash flow difficulties faced by contractor, frequent changes in design, changes in price of materials, poor planning by client, change in scope of project, change in specification of materials and delay in taking decisions. This study will assist contractors to narrow down some of the critical factors that would lead to cost overrun, and therefore be prepared with the ways to mitigate these problems in construction of highway projects of Sindh province.

    Aquatic noise pollution is largely ignored by the lay public. How experts communicate this issue is critical to move public opinion. In 2010, the Cassa di Risparmio di Gorizia (CaRiGO) bank sponsored the Deaf as a Fish project that included local underwater noise monitoring, a boat census, a pamphlet for nonexperts, and some seminars and public meetings. This project allowed us to raise interest in this issue. Using accurate and understandable language in a light-humored setting goes far toward cultivating trust from a public audience that can be intimidated or suspicious of complicated scientific messaging.

    1998-01-01

    The objective of this research was to tackle several problems that are currently of great importance to NASA. In a liquid rocket engine several complex processes take place that are not thoroughly understood. Droplet evaporation, turbulence, finite rate chemistry, instability, and injection/atomization phenomena are some of the critical issues being encountered in a liquid rocket engine environment. Pulse Detonation Engines (PDE) performance, combustion chamber instability analysis, 60K motor flowfield pattern from hydrocarbon fuel combustion, and 3D flowfield analysis for the Combined Cycle engine were of special interest to NASA. During the summer of 1997, we made an attempt to generate computational results for all of the above problems and shed some light on understanding some of the complex physical phenomena. For this purpose, the Liquid Thrust Chamber Performance (LTCP) code, mainly designed for liquid rocket engine applications, was utilized. The following test cases were considered: (1) Characterization of a detonation wave in a Pulse Detonation Tube; (2) 60K Motor wall temperature studies; (3) Propagation of a pressure pulse in a combustion chamber (under single and two-phase flow conditions); (4) Transonic region flowfield analysis affected by viscous effects; (5) Exploring the viscous differences between a smooth and a corrugated wall; and (6) 3D thrust chamber flowfield analysis of the Combined Cycle engine. It was shown that the LTCP-2D and LTCP-3D codes are capable of solving complex and stiff conservation equations for gaseous and droplet phases in a very robust and efficient manner. These codes can be run on a workstation and personal computers (PC's).

  6. Analysis and control of issues that delay pharmaceutical projects

    Full Text Available Every project will have certain objectives and service levels to be achieved. The success of a project depends on several dimensions like time, cost/budget, quality, etc. and managing a project involves completing the project within time, within budget and with quality to satisfy the users. Because of the significance of health, pharmaceutical companies realized the importance of project management methods and techniques to make available the life saving drugs in time to the needy patients and hospitals. In literature, there is meager information about pharmaceutical project management oriented towards analysis of issues and factors that contribute to the failure or success of projects. This study attempts to analyse different issues that contribute to time delays in pharmaceutical product-based projects, group them under a finite set of prominent factors and identify remedial measures to control those delays. The feedback of project people of some big pharmaceutical firms of Indian sub-continent was collected for this purpose. Exploratory factor analysis (EFA has been used to reduce the reasons for time delays to a limited number of prominent factors and the EFA model has been further examined by confirmatory factor analysis (CFA for its validation. Remedial measures under each factor of time delays have been gathered and a framework designed to mitigate the time delays in pharmaceutical projects. The derived factors that delay the pharmaceutical projects include resource, monitoring & control, scheduling and planning problems. Important remedial measures like blended resource approach, estimation and forecast of shortage of labour and skills, regular quality training, etc. have been recommended.

    1994-05-01

    The Fernald Environmental Management Project (FEMP), formerly known as the Feed Materials Production Center (FMPC), is located on a 1050 acre site approximately twenty miles northwest of Cincinnati, Ohio. The production area of the site covers approximately 136 acres in the central portion of the site. Surrounding the core production area is a buffer consisting of leased grazing land, reforested land, and unused areas. The uranium processing facility was designed and constructed in the early 1950s. During the period from 1952 to 1989 the site produced uranium feed material and uranium products used in the United States weapons complex. Production at the site ended in 1989, when the site was shut down for what was expected to be a short period of time. However, the FUTC was permanently shut down in 1991, and the site's mission was changed from production to environmental restoration. The objective of this paper is to give an update on activities at the Fernald Site and to describe the Nuclear Criticality Safety issues that are currently being addressed

    2011-01-01

    Concluding Comments: Firm government commitment and support - imminent; New financing approaches/models are emerging, repackaging existing methods and combination of project finance/co-operative mode; Global financial crisis will make financing for investors very challenging, especially for large scale infrastructure projects like NNP –financial regulators to impose tougher rules (Basel III, UK bank levy, US Financial Regulatory Bill, etc; Pure project finance is still challenging for nuclear projects - the availability of finance for new NPPs will depend on the initial government support. This presentation presents a “free market” view on investment in nuclear power projects; If the public sector (governments) wishes to invest in nuclear power as part of its socioeconomic development priorities, finance is not a real obstacle; It becomes an issue in the presence of other equally important development needs and private sector participation is sought

  12. Criticality issues with highly enriched fuels in a repository environment

    International Nuclear Information System (INIS)

    Taylor, L.L.; Sanchez, L.C.; Rath, J.S.

    1998-03-01

    This paper presents preliminary analysis of a volcanic tuff repository containing a combination of low enrichment commercial spent nuclear fuels (SNF) and DOE-owned SNF packages. These SNFs were analyzed with respect to their criticality risks. Disposal of SNF packages containing significant fissile mass within a geologic repository must comply with current regulations relative to criticality safety during transportation and handling within operational facilities. However, once the repository is closed, the double contingency credits for criticality safety are subject to unremediable degradation, (e.g., water intrusion, continued presence of neutron absorbers in proximity to fissile material, and fissile material reconfiguration). The work presented in this paper focused on two attributes of criticality in a volcanic tuff repository for near-field and far-field scenarios: (1) scenario conditions necessary to have a criticality, and (2) consequences of a nuclear excursion that are components of risk. All criticality consequences are dependent upon eventual water intrusion into the repository and subsequent breach of the disposal package. Key criticality parameters necessary for a critical assembly are: (1) adequate thermal fissile mass, (2) adequate concentration of fissile material, (3) separation of neutron poison from fissile materials, and (4) sufficient neutron moderation (expressed in units of moderator to fissile atom ratios). Key results from this study indicated that the total energies released during a single excursion are minimal (comparable to those released in previous solution accidents), and the maximum frequency of occurrence is bounded by the saturation and temperature recycle times, thus resulting in small criticality risks

    2013-12-01

    This special issue is the fourth of its kind in Journal of Geophysics and Engineering , containing studies and applications of geophysical methodologies and sensing technologies for the knowledge, conservation and security of products of human activity ranging from civil infrastructures to built and cultural heritage. The first discussed the application of novel instrumentation, surface and airborne remote sensing techniques, as well as data processing oriented to both detection and characterization of archaeological buried remains and conservation of cultural heritage (Eppelbaum et al 2010). The second stressed the importance of an integrated and multiscale approach for the study and conservation of architectural, archaeological and artistic heritage, from SAR to GPR to imaging based diagnostic techniques (Masini and Soldovieri 2011). The third enlarged the field of analysis to civil engineering structures and infrastructures, providing an overview of the effectiveness and the limitations of single diagnostic techniques, which can be overcome through the integration of different methods and technologies and/or the use of robust and novel data processing techniques (Masini et al 2012). As a whole, the special issue put in evidence the factors that affect the choice of diagnostic strategy, such as the material, the spatial characteristics of the objects or sites, the value of the objects to be investigated (cultural or not), the aim of the investigation (knowledge, conservation, restoration) and the issues to be addressed (monitoring, decay assessment). In order to complete the overview of the application fields of sensing technologies this issue has been dedicated to monitoring of cultural heritage and critical infrastructures to address safety and security issues. Particular attention has been paid to the data processing methods of different sensing techniques, from infrared thermography through GPR to SAR. Cascini et al (2013) present the effectiveness of a

    Bess, John D.

    2015-01-01

    The Criticality Safety Benchmark Evaluation Project (CSBEP) was initiated in October of 1992 by the United States Department of Energy (DOE). The project quickly became an international effort as scientists from other interested countries became involved. The International Criticality Safety Benchmark Evaluation Project (ICSBEP) became an official activity of the Nuclear Energy Agency (NEA) in 1995. This handbook contains criticality safety benchmark specifications that have been derived from experiments performed at various critical facilities around the world. The benchmark specifications are intended for use by criticality safety engineers to validate calculation techniques used to establish minimum subcritical margins for operations with fissile material and to determine criticality alarm requirements and placement. Many of the specifications are also useful for nuclear data testing. Example calculations are presented; however, these calculations do not constitute a validation of the codes or cross-section data. The evaluated criticality safety benchmark data are given in nine volumes. These volumes span approximately 69000 pages and contain 567 evaluations with benchmark specifications for 4874 critical, near-critical or subcritical configurations, 31 criticality alarm placement/shielding configurations with multiple dose points for each, and 207 configurations that have been categorised as fundamental physics measurements that are relevant to criticality safety applications. New to the handbook are benchmark specifications for neutron activation foil and thermoluminescent dosimeter measurements performed at the SILENE critical assembly in Valduc, France as part of a joint venture in 2010 between the US DOE and the French Alternative Energies and Atomic Energy Commission (CEA). A photograph of this experiment is shown on the front cover. Experiments that are found unacceptable for use as criticality safety benchmark experiments are discussed in these

    Full Text Available Absorption of European funds is on top of Romania’s public agenda for the last years although the first programming period has ended and the necessary lessons were learned so far. To have a high degree of absorption of funds provided by the EU must be of quality projects and their implementation to be successful. Through this work we aimed to investigate the success factors of infrastructure projects with European funding in Romania, Bulgaria, Moldova, Ukraine, Serbia and Kosovo, and identify critical success factors of these projects through a research surveying the teams of consultants and support personnel from the countries in an international consulting company. The research results are therefore constitute the empirical evidence of what constitutes critical success factors of infrastructure projects financed by the European Union and can be used as a starting point for scientific studies of the management of European projects or other actions that investigates measures that can be taken to improve the success rate of projects implemented in the area mentioned above.One of the contributions of this paper is to identify the critical success factors of success factors present in literature. With more so as they are critical success factors of infrastructure projects with European funding still required field studies and analysis performed in the present context. In addition, the critical factors were operationalized in a conceptual framework. Moreover, this framework includes leadership style of project manager as critical success factor has been identified in the research as the most important in the context in which it was conducted. As such, this paper demonstrates, with the necessary limitations, the importance of management style of project managers in the context of specific European funded infrastructure projects. And this is happening even though there are sophisticated project management tools availabe and relevant knowledge exists

    2014-01-01

    Full Text Available The use of public–private partnerships (PPPs is growing in the United States in response to reductions in funding combined with an aging highway transportation infrastructure. Many other countries have longer experience with PPP and a greater understanding of the issues surrounding their use. The main governance issues to be addressed in PPPs deal with risk-sharing, relationships, contracts, and legal framework, and standard processes within dedicated organizational units. These governance issues are examined in the context of a case study for the US 36 Phase II PPP in Colorado. Findings suggest that for the US Phase II project, governance issues are resolved through more relational forms than prescriptive contractual language. Colorado has established a dedicated organizational unit to facilitate the use of PPPs, but there exist no standards or best practices in the United States for procurement, concession terms, or risk-sharing.

    The Slagging Pyrolysis Incinerator (SPI) Facility is being developed to process transuranic waste stored and buried at the Idaho National Engineering Laboratory (INEL) into a chemically inert, physically stable, basalt-like residue acceptable for a Federal Repository. A task force was established by the SPI Project Division to review and assess all aspects of criticality safety for the SPI Facility. This document presents the initial review, evaluations, and recommendations of the task force and includes the following: background information on waste characterization, and criticality control approaches and philosophies, a description of the SPI Facility Waste Processing Building, a review and assessment of potentially relevant codes and regulations; a review and assessment of the present state of criticality and assaying/monitoring studies, and recommendations for changes in and additions to these studies. The review and assessment of potentially relevant codes and regulations indicate that ERDAM 0530, Nuclear Criticality Safety should be the controlling document for criticality safety for the SPI Project. In general, the criticality control approaches and philosophies for the SPI Project comply with this document

There is a broad consensus that clearly defined tenure rights are important for the implementation and success of REDD+, both to manage forests effectively and to protect local communities’ livelihoods. We use primary data from 23 villages in six REDD+ pilot sites in Tanzania to identify causes of deforestation and forest degradation, and tenure rights issues, at the village level prior to project implementation. Further, interviews with project proponents and examination of project documents yields insights into how the proponents plan to address tenure issues. Most villages perceive their tenure as secure and have exclusion rights, while collective action challenges are prevalent in villages experiencing deforestation and forest degradation. These findings suggest that the main tenure issues are related to internal institutional arrangements. While we find that tenure is high on the agenda for all the project proponents, they are mainly focusing on formalization and securing tenure rights from state to community level. Though we do find this to be a precondition for reducing deforestation and degradation, some of their focus should be shifted to strengthening village institutions and enhancing internal compliance.

    The evolution of Federal involvement with nuclear criticality safety has traversed through the 1940's and early 1950's with the Manhattan Engineering District, the 1950's and 1960's with the Atomic Energy Commission, the early 1970's with the Energy Research and Development Administration, and the late 1970's to date with the US Department of Energy. The importance of nuclear criticality safety has been maintained throughout these periods; however, criticality safety has received shifting emphases in research/applications, promulgations of regulations/standards, origins of fiscal support and organization. In June 1981 the Office of Nuclear Safety was established in response to a Department of Energy study of the impact of the March 1979 Three Mile Island accident. The organizational structure of the ONS, its program for establishing and maintaining a progressive nuclear criticality safety program, and associated projects, and current history of ONS's fiscal support of program projects is presented. With the establishment of the ONS came concomitant missions to develop and maintain nuclear safety policy and requirements, to provide independent assurance that nuclear operations are performed safely, to provide resources and management for DOE responses to nuclear accidents, and to provide technical support. In the past four years, ONS has developed and initiated a continuing Department Nuclear Criticality Safety Program in such areas as communications and information, physics of criticality, knowledge of factors affecting criticality, and computational capability

  6. Alternate measurements of benefit to criticality issues at Hanford

    Toffer, H.; Cabrilla, D.E.

    1997-06-01

    Measurements in a critical mass facility, such as the Los Alamos Critical Experiments Facility, could be performed on simulated nuclear waste materials that would provide important critical mass information and concurrently provide a calibration of alternate measurement techniques. In addition to criticality information, the measurements could also provide a better assessment of diluent material/neutron interaction cross sections. An Hanford, large quantities of fissionable materials are dispersed in tanks, fuel storage pools, and in solid waste. Although the fissionable materials are well diluted by a variety of neutron-moderating and -absorbing substances, it is difficult to assess the margin of subcriticality. A number of measurement approaches are proposed that will either help determine fissionable material concentrations, distributions, or provide a direct measure of subcriticality. The methods under consideration involve passive neutron counting, active neutron measurements, pulse neutron applications, neutron noise analyses, and cover gas evaluations. Active neutron measurements can also provide insight into the determination of neutron absorber concentrations. Efforts are underway to test some of the methods in actual waste tank environments and geometries. It is important that these methods be tested and calibrated in a critical mass facility.

    2014-02-01

    Full Text Available As a developing country, Malaysian is currently driving for implementing a new or modern construction method, the Industrialised Building System (IBS, as an alternative towards enhancing construction performance. Currently, most of the IBS project developments in Malaysia are still conducted by using the traditional construction process approach. This traditional construction process has been widely criticised for its fragmented approach to project delivery and its failure to form effective teams thus created a number of issues such as reworks, time delay, rising costs, lack of communication and coordination, and wastages. This paper through literature review aims to highlight this fragmentation issue and clarify how far it affects the process of IBS implementation. Suggestions on how an integrated approach in design and construction in order to minimise the fragmentation gaps will be concluded.

    A telehealth network based at the Medical College of Georgia was established in 2003 to treat stroke patients in remote hospitals. In the first three years, more than 400 patients were evaluated at nine rural hospitals. A total of 65 patients (16%) were treated with tissue plasminogen activator (approximately half of them in less than 2 h). Although clinically successful, the system reached the point at which it would either further diffuse or die out. We examined the roles played by internal and external factors in the development of the system. We interviewed 25 individuals in five hospitals (the hub hospital and four rural hospitals). Important business issues were identified that would need to be addressed in order to expand the project and make it self-sustaining. The external factors were economic, legal and market issues. The internal factors were organizational, technical and educational issues. Early identification and negotiation of business issues related to project implementation are likely to be important in diffusion and sustainability.

    1991-01-01

    A Halden Reactor Project Workshop on 'Understanding Advanced Instrumentation and Controls Issues' was held in Halden, Norway, during June 17-18, 1991. The objectives of the workshop were to (1) identify and prioritize the types of technical information that the Halden Project can produce to facilitate the development of man-machine interface guidelines and (2) to identify methods to effectively integrate and disseminate this information to signatory organizations. As a member of the Halden Reactor Project, the Nuclear Regulatory Commission (NRC) requested the workshop. This request resulted from the NRC's need for human factors guidelines for the evaluation of advanced instrumentation and controls. The Halden Reactor Project is a cooperative agreement among several countries belonging to the Organization for Economic Cooperation and Development (OECD). The US began its association with the Halden Project in 1958 through the Atomic Energy Commission. The project's activities are centered at the Halden heavy-water reactor and its associated man-machine laboratory in Halden, Norway. The research program conducted at Halden consists of studies on fuel performance and computer-based man-machine interfaces

    The International Criticality Safety Benchmark Evaluation Project (ICSBEP) was initiated in 1992 by the United States Department of Energy. The ICSBEP became an official activity of the Organisation for Economic Cooperation and Development (OECD) - Nuclear Energy Agency (NEA) in 1995. Representatives from the United States, United Kingdom, France, Japan, the Russian Federation, Hungary, Republic of Korea, Slovenia, Yugoslavia, Kazakhstan, Israel, Spain, and Brazil are now participating. The purpose of the ICSBEP is to identify, evaluate, verify, and formally document a comprehensive and internationally peer-reviewed set of criticality safety benchmark data. The work of the ICSBEP is published as an OECD handbook entitled 'International Handbook of Evaluated Criticality Safety Benchmark Experiments.' The 2003 Edition of the Handbook contains benchmark model specifications for 3070 critical or subcritical configurations that are intended for validating computer codes that calculate effective neutron multiplication and for testing basic nuclear data.

  20. The value of criticality: Gauging issues in supply nets

    Directory of Open Access Journals (Sweden)

    Jochen Speyerer

    2005-06-01

    Full Text Available Modern day supply chains encompass both geographically disparate activities and planning processes for multiple companies or various interdependent time horizons. To be able to effectively manage these supply chains it is not only necessary to strategically plan the future of the underlying network of participating companies but also to schedule and monitor the ongoing production and logistics activities on a regular basis. Unfortunately, available information systems do not provide an adequate way to handle disruptions. If at all, they employ inter-organizational workflows to keep track of activities and notify a pre-set recipient in case something goes wrong. But in order to be able to focus their attention on urgent problems, managers need a means to gauge the criticality of a symptom. This paper tries to fill this gap by introducing a Value of Criticality (VoC that indicates how serious the faced deviation really is.

  3. The environmental Kuznets curve (EKC) theory. Part B: Critical issues

    International Nuclear Information System (INIS)

    Kaika, Dimitra; Zervas, Efthimios

    2013-01-01

    According to the environmental Kuznets curve (EKC) theory, the process of economic growth is expected to limit the environmental degradation created in the early stages of development. The first article of this study reviews the empirical studies examining various factors, other than income, that may lead to an EKC-pattern. The current article reviews in the first part the major critiques on the EKC-speculation which relate to the following issues: the normal distribution of world income, the feedback from environmental degradation to economic growth, the characteristics of the pollutant in question, various econometric issues, the evolution of consumption when income rises and the assumption about a common developmental pattern in all countries. The second part discusses additional matters reported indirectly in the literature and/or must be further examined. There are doubts whether the GDP-series captures the transition of production to the three productive sectors in empirical estimations and whether services are less polluting compared to industry activities. Finally, the original Kuznets-theory, which laid the groundwork for the EKC-concept, does not seem to solve income inequality problems. - Highlights: • The basic critiques on the EKC-concept are presented. • Some additional issues, not explicitly presented in the literature, must be further examined. • The examination of such critiques is essential to define the validity-bounds of the EKC-concept. • The construction of structural models comes up to be more urgent than ever

  4. Critical thinking by nurses on ethical issues like the termination of pregnancies.

    2000-09-01

    This research forms part of a larger interdisciplinary research project on the termination of pregnancies. The focus of this part of the project is on the ethical issues related to termination of pregnancies. The practice of the professional nurse is confronted with ethical dilemmas and disputes. Whether the nurse chooses to participate in the termination of pregnancies or not, the core function of the nurse is that of counseling and ethical decision-making. Effective counseling requires empathy, respect for human rights and unconditional acceptance of a person. Making ethical decisions implies making critical decisions. It is self-evident, therefore, that such decisions should be based on sound arguments and logical reasoning. It is of vital importance that ethical decisions can be justified on rational ground. Decision-making is a critical thinking approach process for choosing the best action to meet a desired goal. The research question that is relevant for this paper is: Are nurses thinking critically about ethical issues like the termination of pregnancies? To answer the research question a qualitative, exploratory, descriptive design was used (Mouton, 1996:103-169). Registered nurses were selected purposively (Creswell, 1994:15). 1200 registered nurses completed the open-ended questionnaires. Focus group interviews were conducted with 22 registered nurses from a public hospital for women and child health services. Data analysis, using secondary data from open-ended questionnaires and transcribed focus group interviews, were based on the approach of Morse and Field (1994:25-34) and Strauss and Corbin (1990). The themes and categories from open coding were compared, conceptualized and linked with theories on critical thinking (Paul, 1994; Watson & Glaser, 1991 and the American Philosophical Association, 1990). The measures of Lincoln and Guba (1985) and Morse (1994) related to secondary data analysis were employed to ensure trustworthiness. Based on these

    2000-06-01

    Informed consent (IC), a fundamental principle of ethics in medical research, is recognized as a vital component of HIV vaccine trials. There are different notions of IC, some legally based and others based on ethics. It is argued that, though legal indemnity is necessary, vaccine trials should be founded on fully ethical considerations. Various contentious aspects of IC are examined, especially the problem of social desirability and of adequate comprehension. The need for sensitivity to cultural norms in implementing IC procedures is critically reviewed, and some of the potential conflict between ethos and ethics is considered. The transmission of information is examined as a particular aspect of IC in HIV vaccine trials.

    A team from the Universities of Wisconsin, Washington, and Illinois performed an engineering scoping study of critical issues for field-reversed configuration (FRC) power plants. The key tasks for this research were (1) systems analysis for deuterium-tritium (D-T) FRC fusion power plants, and (2) conceptual design of the blanket and shield module for an FRC fusion core. For the engineering conceptual design of the fusion core, the project team focused on intermediate-term technology. For example, one decision was to use steele structure. The FRC systems analysis led to a fusion power plant with attractive features including modest size, cylindrical symmetry, good thermal efficiency (52%), relatively easy maintenance, and a high ratio of electric power to fusion core mass, indicating that it would have favorable economics.

    This research was undertaken to provide NASA with a survey of state-of-the-art techniques using in industrial and academia to provide safe, reliable, and maintainable software to drive large systems. Such systems must match the complexity and strict safety requirements of NASA's shuttle system. In particular, the Launch Processing System (LPS) is being considered for replacement. The LPS is responsible for monitoring and commanding the shuttle during test, repair, and launch phases. NASA built this system in the 1970's using mostly hardware techniques to provide for increased reliability, but it did so often using custom-built equipment, which has not been able to keep up with current technologies. This report surveys the major techniques used in industry and academia to ensure reliability in large and critical computer systems.

    The population dynamic and the immigration trends in the United States continue to challenge health care professionals who each day must serve an increasingly diverse population. Today's physicians must not only have a solid background in medical sciences but they must also have knowledge of how culture, race, and ethnicity impact how patients view and accept traditional Western practices. Whether doctors and patients are close in the "context spectrum" will often determine their ability to communicate beyond the spoken language. According to a report of the American Medical Association, by the year 2000, out of a total 812,770 physicians, only 2.5% were Black, 3.5% Hispanic, and 8.9% Asian. Only a fraction of a percent was American Native/Alaskan Native. Therefore, the majority of the physicians are Caucasian, and it could be assumed that they would likely be accustomed to high-context communication styles. The gross of the demographic changes and population increases in the United States during the past 10 years can be attributed to immigration from regions of the world where low-context communication styles are prevalent. Such differences between physicians and patients can create difficult, tense situations in an already charged atmosphere as can be that of a critical care unit.

    Full Text Available Construction projects play an important role in the advancement of a nation through infrastructure development that leads to economic growth. They are planned carefully to accomplish certain goals. However, not all the projects achieved the goals as per planned. Many factors contribute to the successes and failures, and it becomes an interesting arena for research. The primary objective of this paper is to outline the development trend of project success measurement globally and locally. The research method employed was to make selected reviews on critical success factors' (CSFs literature and to compare international standards and progress in incorporating human behavioural aspects of project management to the situation in Malaysia. A somewhat similar pattern can be observed in Malaysia where the studies have departed from the usual criteria of time, cost and quality, to define project success in a more holistic way. However, the domestic industry has failed to respond to the emerging trend globally as there has yet been any widely published research on the importance of human-related factors towards project success. A consolidated framework of CSFs has therefore, been proposed in responding to the findings. This paper fulfils an identified need as there has been a dearth of research on the subject matter locally.

    The translation of energy concerns into effective policies under a democratic regime is currently impaired by two interrelated factors: (1) the interdependency of energy goals with most of society's other concerns and (2) the indeterminateness of both the scientific evidence and public interest. Some of the manifestations of the failure to address these factors are the prevailing energy policy uncertainties and the polarization of values, issues and research efforts. Awareness of this reality has not prevented, however, the suggestion of policies the majority of which either neglect the synergistic effect of the factors or depend for their legitimization on principles incompatible with democratic decision-making. I suggest that systematic examination of the web of interdependencies and of the scientific and public interest indeterminateness supports the assertion that the effectiveness of energy use management will depend on: (i) supplementing quantitative research with qualitative evaluation of scientific and public values; (ii) synthesizing the findings of the numerous currently performed analyses; and (iii) substituting the paternalistic dictates of scientists and special interest groups as the basis for policy decision-making with a participatory process that will aim to maximize the accord among all interested in, and/or impacted by, energy policies.

    2001-01-01

    There are two complementary approaches to studying the environmental effects of fuel use and energy conversion. The first is to be completely systematic and to follow through each technology in great detail, and itemise each impact, whether large or small. The second, followed here, is to pick out those items that either dominate the risk or impact, or dominate the public perception therefore, and try to understand them in some detail. I pick the following that I believe are the most important environmental issues today: 1 What is the effect of particulate air pollution on today's levels? 2 What is the probability that carbon dioxide emissions will cause global warming? 3 Can we use this energy source in a sustainable fashion over several millennia? I will spend much of the space on a discussion of these three. However, there are a number of other items that some group or another think are important. They must also be considered to sufficient extent to persuade everyone involved that indeed they are less important. These include: 4 What is the probability and effect of a severe nuclear power accident? 5 Why is there public concern about nuclear waste although it is not justified by the calculations? 6 Why are hydroelectric dams not as universally popular as they were? 7 Can we avoid the proliferation of bombs using plutonium if we have a nuclear power program? 8 Can we reduce the cost of electricity from nuclear power to what is was 25 years ago?

    2005-12-01

    Organizational changes focused on process orientation are taking place among Swedish nuclear power plants, aiming at improving the operation. The Swedish Nuclear Power Inspectorate has identified a need for increased knowledge within the area for its regulatory activities. In order to analyze what process orientation imply for nuclear power plant safety a number of questions must be asked: 1. How is safety in nuclear power production created currently? What significance does the functional organization play? 2. How can organizational forms be analysed? What consequences does quality management have for work and for the enterprise? 3. Why should nuclear power plants be process oriented? Who are the customers and what are their customer values? Which customers are expected to contribute from process orientation? 4. What can one learn from process orientation in other safety critical systems? What is the effect on those features that currently create safety? 5. Could customer values increase for one customer without decreasing for other customers? What is the relationship between economic and safety interests from an increased process orientation? The deregulation of the electricity market have caused an interest in increased economic efficiency, which is the motivation for the interest in process orientation. among other means. It is the nuclear power plants' owners and the distributors (often the same corporations) that have the strongest interest in process orientation. If the functional organization and associated practices are decomposed, the prerequisites of the risk management regime changes, perhaps deteriorating its functionality. When nuclear power operators consider the introduction of process orientation, the Nuclear Power Inspectorate should require that 1. The operators perform a risk analysis beforehand concerning the potential consequences that process orientation might convey: the analysis should contain a model specifying how safety is currently

    Full Text Available Abstract Background There are many challenges involved in running randomised controlled dietary intervention trials that investigate health outcomes. The aim of this paper was to evaluate the recruitment process, retention of participants and challenges faced in our dairy intervention trial, and to provide strategies to combat the difficulties of running long-term dietary intervention trials. Methods A 12-month, randomised, two-way crossover study was conducted in overweight adults with habitually low dairy food consumption to assess the effects of a high dairy intake (4 servings of reduced-fat dairy per day compared with a low dairy intake (1 serving of reduced-fat dairy per day on measures of cardiometabolic and cognitive health. On completion of the high dairy intake phase, each participant was interviewed about their experience in the trial and responses were used to evaluate the key issues for study participants. Results Although the recruitment target was achieved, high rates of attrition (49.3% and difficulties maintaining participant compliance (reported by 37.8% of participants were major threats to the viability of the study. Factors that contributed to the high attrition included inability to comply with the dietary requirements of the study protocol (27.0%, health problems or medication changes (24.3% and time commitment (10.8%. Conclusion Attrition and adherence to study requirements present challenges to trials requiring longer-term dietary change. Including a run-in period to further assess the motivation, commitment and availability of participants, maintaining regular contact with participants during control phases, minimising time commitment, providing flexibility with dietary requirements, facilitating positive experiences, and stringent monitoring of diet are some key recommendations for future dietary intervention trials.

    Although the philosophy of science and of specific sciences such as physics, chemistry, and biology are well-developed fields with their own books and journals, the philosophy of astronomy and cosmology have received little systematic attention. At least six categories of problems may be identified in the astronomical context: 1) the nature of reasoning, including the roles of observation, theory, simulation, and analogy, as well as the limits of reasoning, starkly evident in the anthropic principle, fine-tuning, and multiverse controversies; 2) the often problematic nature of evidence and inference, especially since the objects of astronomical interest are for the most part beyond experiment and experience;3) the influence of metaphysical preconceptions and non-scientific worldviews on astronomy, evidenced, for example in the work of Arthur S. Eddington and many other astronomers; 4) the epistemological status of astronomy and its central concepts, including the process of discovery, the problems of classification, and the pitfalls of definition (as in planets); 5) the role of technology in shaping the discipline of astronomy and our view of the universe; and 6) the mutual interactions of astronomy and cosmology with society over time. Discussion of these issues should draw heavily on the history of astronomy as well as current research, and may reveal an evolution in approaches, techniques, and goals, perhaps with policy relevance. This endeavor should also utilize and synergize approaches and results from philosophy of science and of related sciences such as physics (e.g. discussions on the nature of space and time). Philosophers, historians and scientists should join this new endeavor. A Journal of the Philosophy of Astronomy and Cosmology (JPAC) could help focus attention on their studies.

  5. Examination of the relationship between project management critical success factors and project success of oil and gas drilling projects

    Science.gov (United States)

    Alagba, Tonye J.

    Oil and gas drilling projects are the primary means by which oil companies recover large volumes of commercially available hydrocarbons from deep reservoirs. These types of projects are complex in nature, involving management of multiple stakeholder interfaces, multidisciplinary personnel, complex contractor relationships, and turbulent environmental and market conditions, necessitating the application of proven project management best practices and critical success factors (CSFs) to achieve success. Although there is some practitioner oriented literature on project management CSFs for drilling projects, none of these is based on empirical evidence, from research. In addition, the literature has reported alarming rates of oil and gas drilling project failure, which is attributable not to technical factors, but to failure of project management. The aim of this quantitative correlational study therefore, was to discover an empirically verified list of project management CSFs, which consistent application leads to successful implementation of oil and gas drilling projects. The study collected survey data online, from a random sample of 127 oil and gas drilling personnel who were members of LinkedIn's online community "Drilling Supervisors, Managers, and Engineers". The results of the study indicated that 10 project management factors are individually related to project success of oil and gas drilling projects. These 10 CSFs are namely; Project mission, Top management support, Project schedule/plan, Client consultation, Personnel, Technical tasks, Client acceptance, Monitoring and feedback, Communication, and Troubleshooting. In addition, the study found that the relationships between the 10 CSFs and drilling project success is unaffected by participant and project demographics---role of project personnel, and project location. The significance of these findings are both practical, and theoretical. Practically, application of an empirically verified CSFs list to oil

    Public Private Partnership (PPP) in Malaysia aims to stimulate economic growth and overcome the weakness of conventional system. Over the years, many critics have been reported along the massive growth of PPP project development. Within that context, this study provides a review of issues and challenges for PPP pertaining to project performance in Malaysia. The study also attempts to investigate four performance measurement models around the globe as a basis for improvement of PPP in Malaysia. A qualitative method was used to analyse literature review from previous published literatures while comparative analysis was carried out within the models to identify their advantages and disadvantages. The findings show that the issues and challenges occurred were related to human, technical and financial factor that could hinder the implementation of PPP project in Malaysia. From the analysis, KPIs, guideline / framework, risk allocation, efficiency & flexibility are perceived as dominant issues. Finally, the findings provide an informed basis on the opportunity areas to be considered for improvement in order to achieved project effectiveness.

  7. Regulatory compliance issues related to the White Oak Creek Embayment time-critical removal action

    1992-01-01

    In September 1990, Martin Marietta Energy Systems (Energy Systems) discovered high levels of Cesium-137 present in surface sediments at the mouth of White Oak Creek (WOC) Embayment. WOC receives the majority of surface water drainage from Oak Ridge National Laboratory. Following this discovery, the Department of Energy (DOE) and Energy Systems pursued stabilizing sediment migration under provisions of the National Contingency Plan (NCP) Section 300.400 et. seq. as a time-critical removal action. However, significant uncertainty exists concerning the applicability of NCP procedural requirements designed for conducting US EPA-led, Superfund-financed response actions, because NCP Subpart K dealing with response actions at federal facilities has not been promulgated. In addition, relatively new guidance exists from DOE concerning National Environmental Policy Act documentation requirements for categorical exclusions associated with conducting removal actions at DOE facilities. A proactive approach was taken to identify issues and involve appropriate state and federal regulatory agencies. This approach required achieving consensus among all involved parties and identification of all applicable or relevant and appropriate regulatory requirements related to the removal action. As a result, this project forms a framework for conducting future time-critical removal actions at federal facilities

    Carbon dioxide capture and storage (CCS) provides options for making continued use of fossil fuels more compatible with pollution abatement policies. This paper evaluated policy issues related to CCS, with particular focus on the geological sequestration of carbon dioxide (CO 2 ) into geological storage sites. Before any carbon dioxide (CO 2 ) CCS activities can be included in the portfolio of climate change mitigation activities, several issues need to be resolved such as the development of appropriate accounting and baselines rules and monitoring modalities. Guidance and policies on baselines and the accounting of emission reductions are critical to ensure that CCS projects can benefit from CO 2 markets and are recognized under various mitigation schemes. This paper examined the major issues that should considered along with changes to current accounting approaches. Issues that need to be addressed in order to prepare national inventories for the inclusion of CCS under the United Nations Framework Convention on Climate Change (UNFCCC) and emission reduction schemes such as the European greenhouse gas emissions trading scheme were first presented, followed by an examination of CCS issues under project-based mechanisms such as the Kyoto Protocol's Clean Development Mechanism. The importance of clear definitions and monitoring guidelines for the proper accounting of CCS were also highlighted. 12 refs., 2 figs

    The Transuranic Waste Treatment Facility (TWTF) is being developed to process transuranic waste, stored and buried at the Idaho National Engineering Laboratory, into a chemically inert, physically stable basalt-like residue acceptable at a federal repository. A task force was assembled by the TWTF Project Division to review and assess all aspects of criticality safety for the TWTF. This document presents the final review, assessments, and recommendations of this task force. The following conclusions were made: Additional criticality studies are needed for the entire envelope of feed compositions and temperature effects. Safe operating k/sub eff/'s need to be determined for process components. Criticality analyses validation experiments may also be required. SRP neutron interrogation should be replaced by DDT neutron interrogation. Accuracy studies need to be performed for the proposed assaying techniques. Time-correlated neutron monitoring needs to be mocked up for process components to prove feasibility and determine accuracy. The criticality control techniques developed for the TWTF conceptual design are in compliance with ERDAM 0530, including the Double Contingency Rule. Detailed procedures and controls need to be developed

  10. The nuclear criticality information system's project to archive unpublished critical experiment data

    Critical experiment facilities produced a large amount of important data during the past forty-five years. However, much useful data remains unpublished. The unpublished material exists in the form of experimenters' logbooks, notes, photographs, material descriptions, etc. These data could be important for computer code validation, understanding the physics of criticality, facility design, or for setting process limits. In the past, criticality specialists have been able to obtain unpublished details by direct contact with the experimenters. The closure of facilities and the loss of personnel is likely to lead to the loss of the facility records unless an effort is made to ensure that the records are preserved. It has been recognized for some time that the unpublished records of critical experiment facilities comprise a valuable resource, thus the Nuclear Criticality Information System (NCIS) is working to ensure that the records are preserved and made available via NCIS. As a first step in the archiving project, we identified criteria to help judge which series of experiments should be considered for archiving. Data that are used for validating calculations or the basis for subcritical limits in standards, handbooks, and guides are of particular importance. In this paper we will discuss the criteria for archiving, the priority list of experiments for archiving, and progress in developing an NCIS image database using current CD-ROM technology. (Author)

    Full Text Available All construction professionals such as civil, mechanical, and electrical engineers, quantity surveyors, and architects have important roles in the construction process. Among these, architects are frequently appointed as a project manager (PM. The role of a PM will drive the success of the projects implementation. Therefore, the capability of an architect as a PM (ArPM is critical in reducing challenges encountered. Accordingly, the identification of these challenges is an important task in selecting an appropriate ArPM. The aim of this study is to identify the most critical challenges faced by an ArPM for construction projects. The data were collected through questionnaires and interviews with architects and professionals in the Malaysian construction industry. Because of the fuzziness and uncertainty of subjective responses, Fuzzy Set Ttheory is applied to identify critical challenges. A total of 65 questionnaires were distributed and 36 questionnaires were returned. The results revealed that the critical challenges faced by an ArPM are “poor planning,” “unfamiliar technology,” “unfamiliarity with green buildings and materials,” “inappropriate scheduling,” and “poor workmanship.” All critical challenges were then categorized into six main groups including technical, managerial, personal skills, contractual, psychological, and financial.

    2004-07-01

    Recently, science centers have created issues-based exhibitions as a way of communicating socioscientific subject matter to the public. Research in the last decade has investigated how critical issues-based installations promote more robust views of science, while creating effective learning environments for teaching and learning about science. The focus of this paper is to explore research conducted over a 10-year period that informs our understanding of the nature of learning through these experiences. Two specific exhibitions - Mine Games and A Question of Truth - provide the context for discussing this research. Findings suggest that critical issues-based installations challenge visitors in different ways - intellectually and emotionally. They provide experiences beyond usual phenomenon-based exhibitions and carry the potential to enhance learning by personalizing subject matter, evoking emotion, stimulating dialogue and debate, and promoting reflexivity. Critical issues-based exhibitions serve as excellent environments in which to explore the nature of learning in these nonschool settings.

  20. How public issues shape environmental restoration plans - experiences with Colorado UMTRA projects

    1991-01-01

    Federal environmental restoration plans are being significantly impacted by open-quotes grassrootsclose quotes public pressure and by community demands, some of which have little relation to the technical standards of remediation and which go well beyond authorizing legislation. These demands often represent significant additional project costs. A review of Uranium Mill Tailings Remedial Action (UMTRA) Program experiences in Colorado suggests that the more serious open-quotes grassrootsclose quotes issues associated with remediation rarely diminish and, in fact, will intensify over time. This presents program administrators with the dilemma of attempting to adhere to program mandates and keep projects within budget, while at the same time trying to be responsive to community concerns. Such high-profiled community debates have the ability to delay remediation and even jeopardize important projects. After prolonged public debate, when it becomes clear an issue will not dissipate, project officials may be forced to meet certain community demands. Often, this results in not only increased costs, but a loss of public confidence in clean-up efforts. Evidence also suggests, however, that when critical public issues can be identified and addressed before they become overly contentious, significant problems and controversy can be avoided; but, the situation is made difficult because project officials often lack the policy guidance to determine which, if any, community demands should be addressed and to what extent they should be met. The adoption of several key public policy principles by program administrators will provide a greater ability to address community demands in a timely and successful manner

    Full Text Available American society faces complex educational issues which impact many facets of its national interests. Institutions of higher education are granting doctoral degrees to educational leaders, but it is not known to what extent their dissertation topics are aligned with both longstanding and critical issues in education. Using a theoretical framework synthesizing Paul and Elder’s critical thinking model and Kuhlthau’s information seeking process, this study examines a set of education doctoral dissertation topical selections and categorizes them by general themes in relationship to many of the recognized educational issues in the United States. Investigators categorized dissertations from four departments within the College of Education of their home institution. The dataset, retrieved from ProQuest Dissertations and Theses Global, consisted of 231 documents published between 2005 and 2014. Through an inter-rater process examining dissertation titles, abstracts, and keywords, the dissertations were assigned critical issue themes culled from nine editions of a college text, and then categorized under a broader topical scheme situated within a well-used educational research website. Findings indicated that most dissertations concentrated in studies that researched problems and issues within schools. Further, some of the issues considered longstanding were not studied by dissertation authors within the sample. For example, privatization of schools and classroom discipline and justice were not selected for study. Findings also suggest new directions for those responsible for dissertation supervision and topic selection. The study adds to the literature on dissertation topic selection that addresses existing educational issues.

    2011-06-01

    Full Text Available Recently, the critical chain study has become a hot issue in the project management research field. The construction of the critical chain with multi-resource constraints is a new research subject. According to the system analysis theory and project portfolio theory, this paper discusses the creation of project portfolios based on the similarity principle and gives the definition of priority in multi-resource allocation based on quantitative analysis. A model with multi-resource constraints, which can be applied to the critical chain construction of the A-bid section in the South-to-North Water Diversion Project, was proposed. Contrast analysis with the comprehensive treatment construction method and aggressive treatment construction method was carried out. This paper also makes suggestions for further research directions and subjects, which will be useful in improving the theories in relevant research fields.

  19. Review of criticality safety and shielding analysis issues for transportation packages

    International Nuclear Information System (INIS)

    Parks, C.V.; Broadhead, B.L.

    1995-01-01

    The staff of the Nuclear Engineering Applications Section (NEAS) at Oak Ridge National Laboratory (ORNL) have been involved for over 25 years with the development and application of computational tools for use in analyzing the criticality safety and shielding features of transportation packages carrying radioactive material (RAM). The majority of the computational tools developed by ORNL/NEAS have been included within the SCALE modular code system (SCALE 1995). This code system has been used throughout the world for the evaluation of nuclear facility and package designs. With this development and application experience as a basis, this paper highlights a number of criticality safety and shielding analysis issues that confront the designer and reviewer of a new RAM package. Changes in the types and quantities of material that need to be shipped will keep these issues before the technical community and provide challenges to future package design and certification

    1994-01-01

    The critical issues, evaluation and comparison of two inertial fusion energy (IFE) reactor design concepts developed in the Prometheus studies are presented. The objectives were (1) to identify and characterize the critical issues and the R and D required to solve them, and (2) to establish a sound basis for future IFE technical and programmatic decisions by evaluating and comparing the different design concepts. Quantitative evaluation and comparison of the two design options have been made with special focus on physics feasibility, engineering feasibility, economics, safety and environment, and research and development (R and D) requirements. Two key conclusions are made based on the overall evaluation analysis: (1) The heavy-ion driven reactors appear to have an overall advantage over laser-driven reactors; and: (2) The differences in scores are not large and future results of R and D could change the overall ranking of the two IFE concepts

    2000-01-01

    A criticality safety analysis has been performed as part of the BN-350 spent fuel disposition project being conducted jointly by the DOE and Kazakhstan. The Kazakhstan regulations are reasonably consistent with those of the DOE. The high enrichment and severe undermoderation of this fast reactor fuel has significant criticality safety consequences. A detailed modeling approach was used that showed some configurations to be safe that otherwise would be rejected. Reasonable requirements for design and operations were needed, and with them, all operations were found to be safe

  3. High level issues in reliability quantification of safety-critical software

    International Nuclear Information System (INIS)

    Kim, Man Cheol

    2012-01-01

    For the purpose of developing a consensus method for the reliability assessment of safety-critical digital instrumentation and control systems in nuclear power plants, several high level issues in reliability assessment of the safety-critical software based on Bayesian belief network modeling and statistical testing are discussed. Related to the Bayesian belief network modeling, the relation between the assessment approach and the sources of evidence, the relation between qualitative evidence and quantitative evidence, how to consider qualitative evidence, and the cause-consequence relation are discussed. Related to the statistical testing, the need of the consideration of context-specific software failure probabilities and the inability to perform a huge number of tests in the real world are discussed. The discussions in this paper are expected to provide a common basis for future discussions on the reliability assessment of safety-critical software. (author)

  5. Identification of critical factors affecting flexibility in hospital construction projects.

    Science.gov (United States)

    Olsson, Nils E O; Hansen, Geir K

    2010-01-01

    This paper analyzes the dynamics relating to flexibility in a hospital project context. Three research questions are addressed: (1) When is flexibility used in the life cycle of a project? (2) What are the stakeholders' perspectives on project flexibility? And (3) What is the nature of the interaction between flexibility in the process of a project and flexibility in terms of the characteristics of a building? Flexibility is discussed from both a project management point of view and from a hospital architecture perspective. Flexibility in project life cycle and from a stakeholder perspective is examined, and the interaction between flexibility in scope lock-in and building flexibility is investigated. The results are based on case studies of four Norwegian hospital projects. Information relating to the projects has been obtained from evaluation reports, other relevant documents, and interviews. Observations were codified and analyzed based on selected parameters that represent different aspects of flexibility. One of the cases illustrates how late changes can have a significant negative impact on the project itself, contributing to delays and cost overruns. Another case illustrates that late scope lock-in on a limited part of the project, in this case related to medical equipment, can be done in a controlled manner. Project owners and users appear to have given flexibility high priority. Project management teams are less likely to embrace changes and late scope lock-in. Architects and consultants are important for translating program requirements into physical design. A highly flexible building did not stop some stakeholders from pushing for significant changes and extensions during construction.

  6. Enhancing Rationality: Heuristics, Biases, and The Critical Thinking Project

    Directory of Open Access Journals (Sweden)

    Mark Battersby

    2016-07-01

    Full Text Available Abstract: This paper develops four related claims: 1. Critical thinking should focus more on decision making, 2. the heuristics and bias literature developed by cognitive psychologists and behavioral economists provides many insights into human irrationality which can be useful in critical thinking instruction, 3. unfortunately the “rational choice” norms used by behavioral economists to identify “biased” decision making narrowly equate rational decision making with the efficient pursuit of individual satisfaction; deviations from these norms should not be treated as an irrational bias, 4. a richer, procedural theory of rational decision making should be the basis for critical thinking instruction in decision making.

    when an issue of water contamination becomes an issue of environmental injustice? How do we measure the impacts of environmental harm today on future generations? How do we measure the distribution of multiple or cumulative impacts on poorer groups? How do we quantify the responsibility of richer citizens in the world for the environmental harms distributed unequally to the poorer citizens? The papers in this focus issue do not answer all these questions, but we hope that this theme will recur in Environmental Research Letters and that more environmental scientists will begin to frame their analyses around the critical issues of distributions of environmental harms and benefits.

    2017-08-01

    Access to clean and stable energy, meeting sustainable development goals, the fossil fuel dependency and depletion are some of the reasons that have impacted developing countries to transform the business as usual economy to a more sustainable economy. However, access and availability of finance is a major challenge for many developing countries. Financing renewable energy projects require access to significant resources, by multiple parties, at varying points in the project life cycles. This research aims to investigate sources and new trends in financing RE projects in developing countries. For this purpose, a detail and in-depth literature review have been conducted to explore the sources and trends of current RE financial investment and projects, to understand the gaps and limitations. This paper concludes that there are various internal and external sources of finance available for RE projects in developing countries.

    Two inertial fusion energy (IFE) reactor design concepts developed in the Prometheus studies were evaluated. Objectives were to identify and characterize critical issues and the R and D required to resolve them, and to establish a sound basis for future IFE technical and programmatic decisions. Each critical issue contains several key physics and engineering issues associated with major reactor components and impacts key aspects of feasibility, safety, and economic potential of IFE reactors. Generic critical issues center around: demonstration of moderate gain at low driver energy, feasibility of direct drive targets, feasibility of indirect drive targets for heavy ions, feasibility of indirect drive targets for lasers, cost reduction strategies for heavy ion drivers, demonstration of higher overall laser driver efficiency, tritium self-sufficiency in IFE reactors, cavity clearing at IFE pulse repetition rates, performance/reliability/lifetime of final laser optics, viability of liquid metal film for first wall protection, fabricability/reliability/lifetime of SiC composite structures, validation of radiation shielding requirements, design tools, and nuclear data, reliability and lifetime of laser and heavy ion drivers, demonstration of large-scale non-linear optical laser driver architecture, demonstration of cost effective KrF amplifiers, and demonstration of low cost, high volume target production techniques. Quantitative evaluation and comparison of the two design options have been made with special focus on physics feasibility, engineering feasibility, economics, safety and environment, and research and development (R and D) requirements. Two key conclusions are made based on the overall evaluation analysis. The heavy-ion driven reactors appear to have an overall advantage over laser-driven reactors.

    2016-03-01

    Full Text Available This paper will illustrate the meaning and importance of human resource management (HRM, human resource planning, and strategic human resource management, which are critically important for an organization’s effectiveness and must be effectively managed (Doherty, 1998. This study used the literature review method to acquire its final results. The relevant HRM literature review was done according to the purpose of the study. It used the purposive random sample method for selecting relevant literature. This study shows the current economic environment in the sports industry; the second part of the study critically analyzes the value of the strategic management of employees for the effective and efficient operation of sports organizations. It also critically evaluates human resource planning and other pertinent issues in terms of legislation, recruitment, selection, training, induction, and reward management from different international examples in sports management. Over the past few decades, increasing competition, globalization, and continuous changes in the market and in technology have emphasized the need to rethink the management of the organization and of human resources for the sake of overcoming significant challenges (Taylor et al., 2006. Therefore, managers should use strategic human resource management to overcome significant issues and to form well-planned strategies so that the organization may succeed.

  18. Critical thinking of classical view of project management

    Institute of Scientific and Technical Information of China (English)

    祁亮

    2015-01-01

    Synopsis:This essay argues that the classic view has to be updated to meet the new demands. It is found out that the scientific manage-ment believes that there are a few essential roles of managers,including planning,organizing,leading,and controlling. There are many impor-tant aspects which lead to the complexity of the modern project management such as globalization and technology. There are many things that are not compatible between the current projects and the traditional theory. It is also considerable to realize that sometimes scholars disagree with each other about the prevalence of complicated projects. However,even if the classic project management theory is useful in certain cases, there is no doubt that such theory demands significant improvements to better suit the current world. Therefore,it is significant that the classic project management theory be upgraded. In order to improve the performances of the project management,it is recommended that stakeholder theory is promoted,decentralized decision making is allowed,and adoption of new technology is recommended.

Pertinent findings from the global survey of low vision services and extensive ground work conducted in the region are used; in addition, a discussion on the availability of services, human resources and training, and funding and the future sustainability of low vision care will be covered. In summary, current issues and challenges facing the region are the lack of specific evidence-based data, access, appropriate equipment and facilities, human resources, funding, and sustainability. These issues are inextricably interlinked and thus cannot be addressed in isolation. The solutions proposed cover all areas of the VISION 2020 strategy that include service delivery, human resources, infrastructure and equipment, advocacy and partnership; and include provision of comprehensive care via vertical and horizontal integration; strengthening primary level care in the community; providing formal and informal training to enable task shifting and capacity building; and promoting strong government and private sector partnership to achieve long-term service financial sustainability.

    The world is facing complex environmental challenges and a changing climate is one of the most pressing. These challenges require innovative solutions, which can only be achieved by first developing a more science and environmentally literate public through high-quality education. We know a lot about how to frame climate change messages to be most effective for adults (1). However, we know much less about how youth respond to these same messages. It is important to engage adolescents in these conversations, as this is the age when kids begin to think more critically and abstractly about complex problems, but also when peer and social influences increase in importance (2). Thus, middle school is a critical point in young students' lives when they might either lose interest in science or gain a strong science identity. To keep them interested and invested in science and environmental issues, we need relevant and transformative climate change materials for use in the classroom—materials that are video-based, compelling, and presented by other youth. The California Academy of Sciences has developed a video-based series with lessons supporting the NGSS called Flipside Science that challenges youth to think critically about complex environmental issues. Exploring Energy: Designing a Brighter Future is a unit within this series that engages youth in thinking about how we can make changes to our current energy uses and behaviors to combat climate change. The videos in the unit are hosted by diverse teens who bring an optimistic and relevant voice to these issues, and the associated lessons engage students in honing their design thinking and problem-solving skills. Although intended for use inside the classroom, these resources inspire action among youth outside of the classroom and in their communities. Initial evaluations of two other Flipside Science units on water and food issues indicate that the youth-powered nature of the videos and the real-world challenges posed

    The aim of this study was to develop an evidence-based communication skills training workshop to improve the communication skills of critical care fellows. Pulmonary and critical care fellows (N = 38) participated in a 3-day communication skills workshop between 2008 and 2010 involving brief didactic talks, faculty demonstration of skills, and faculty-supervised small group skills practice sessions with simulated families. Skills included the following: giving bad news, achieving consensus on goals of therapy, and discussing the limitations of life-sustaining treatment. Participants rated their skill levels in a pre-post survey in 11 core communication tasks using a 5-point Likert scale. Of 38 fellows, 36 (95%) completed all 3 days of the workshop. We compared pre and post scores using the Wilcoxon signed rank test. Overall, self-rated skills increased for all 11 tasks. In analyses by participant, 95% reported improvement in at least 1 skill; with improvement in a median of 10 of 11 skills. Ninety-two percent rated the course as either very good/excellent, and 80% recommended that it be mandatory for future fellows. This 3-day communication skills training program increased critical care fellows' self-reported family meeting communication skills. Copyright © 2014 Elsevier Inc. All rights reserved.

    2013-01-01

    This paper provides new empirical insights on the capital structure of project-financed LNG infrastructures and gas pipeline projects, by using data relating to projects whose financial close occurred between June 2004 and March 2011. Most results are consistent with the basic view of risk-averse funds suppliers. Especially, the projects located in risky countries and larger projects tend to exhibit lower debt ratios and less-concentrated equity ownerships. In addition, regasification projects appear to have a more diluted equity ownership. Methodological issues raised by the financing of these projects are also examined from a capital-budgeting perspective. In particular, the equity residual method, usually used by industrial practitioners to value these projects, should be adjusted. - Highlights: • This paper provides new empirical insights on the capital structure of project-financed LNG and gas pipeline infrastructures. • Most of our results are consistent with the basic view of risk-averse funds suppliers. • Projects located in risky countries exhibit lower debt ratios and less-concentrated equity ownerships. • Larger projects and regasification projects also have less concentrated equity ownerships. • From a capital-budgeting viewpoint, we examine methodological issues raised by the financing of these projects

    Highlights: • 143 voluntary emission reduction projects have been analysed. • The projects belong to renewable energy, energy efficiency and transport sectors. • Voluntary emission reduction standards and methodologies have been applied. • The paper identified the main criticisms for each sector. • Energy efficiency projects are the most promising for public entities. - Abstract: The United Nations Framework Convention on Climate Change (UNFCCC) sets an overall framework for intergovernmental efforts to tackle the challenge posed by climate change. Besides the “flexibility mechanisms” defined by the Kyoto Protocol to lower the overall costs of achieving their emissions targets, The Voluntary Green House Gases (GHG) reduction projects can have a lead role in GHG reduction in “non Emissions Trading System ETS sectors”. Nowadays, the voluntary market is characterised by critical aspects, such as fragmentation, lack of accounting, monitoring and validation rules that have led to the low spread of voluntary emission reduction projects developed by local authorities in the European Union despite their high potentiality. The aim of this paper is to test the applicability of voluntary emission reduction projects in the public sector following a homogeneous and consistent pattern. A research has been performed at local level on 143 voluntary emission reduction projects implemented by Public Administrations in Northern and Central Italy in renewable energy, energy efficiency and transport sectors. The applicable standards and methodologies have been checked and the case studies have been analysed though a three-step process: Preliminary additionality assessment; Projects selection; Validation of the selected project. The assessment shows that energy efficiency projects, once overcoming additionality issues, are the most promising for public entities while renewable energy and transport projects resulted to be mainly affected by double counting problems and

    2018-05-01

    The purpose of this paper is to compare and contrast between two theoretical frameworks for addressing nature of science (NOS) and socioscientific issues (SSI) in school science. These frameworks are critical thinking (CT) and argumentation (AR). For the past years, the first and second authors of this paper have pursued research in this area using CT and AR as theoretical frameworks, respectively. Yacoubian argues that future citizens need to develop a critical mindset as they are guided to (1) practice making judgments on what views of NOS to acquire and (2) practice making decisions on SSI through applying their NOS understandings. Khishfe asserts that AR is an important component of decision making when dealing with SSI and the practice in AR in relation to controversial issues is needed for informed decision making. She argues that AR as a framework may assist in the development of more informed understandings of NOS. In this paper, the authors delve into a dialogue for (1) elucidating strengths and potential of each framework, (2) highlighting challenges that they face in their research using the frameworks in question, (3) exploring the extent to which the frameworks can overlap, and (4) proposing directions for future research.

    2014-04-01

    Speech errors associated with cleft palate are well established for English and several other Indo-European languages. Few articles describing the speech of Putonghua (standard Mandarin Chinese) speakers with cleft palate have been published in English language journals. Although methodological guidelines have been published for the perceptual speech evaluation of individuals with cleft palate, there has been no critical review of methodological issues in studies of Putonghua speakers with cleft palate. A literature search was conducted to identify relevant studies published over the past 30 years in Chinese language journals. Only studies incorporating perceptual analysis of speech were included. Thirty-seven articles which met inclusion criteria were analyzed and coded on a number of methodological variables. Reliability was established by having all variables recoded for all studies. This critical review identified many methodological issues. These design flaws make it difficult to draw reliable conclusions about characteristic speech errors in this group of speakers. Specific recommendations are made to improve the reliability and validity of future studies, as well to facilitate cross-center comparisons.

    2012-03-01

    Full Text Available The debate about the possibilities to engineer the Earth's climate has changed drastically in the last years. Suggestions of large-scale technological interventions to combat climate change that a decade ago would have been discarded as science fiction are slowly moving into the center of international climate change discussions, research, and politics. In this article, I elaborate three joint key challenges to geo-engineering research from a resilience perspective, with a special emphasis on governance issues. First, I discuss the need to understand geo-engineering proposals from a "planetary boundaries" perspective. Second, I elaborate why the notion of Earth stewardship and geo-engineering are not necessarily in conflict, but instead could be viewed as complementary approaches. Last, I discuss the critical need to explore an institutional setting that is strong enough to weed out geo-engineering proposals that carry considerable ecological risk, but still allow for novelty, fail-safe experimentation, and continuous learning. These issues are critical for our understanding of how to effectively govern global environmental risks, complex systems, and emerging technologies in the Anthropocene.

    Full Text Available Many studies have shown that the construction industry one of the most hazardous industries with its high rates of fatalities and injuries and high financial losses incurred through work related accident. To reduce or overcome the safety issues on construction sites, different safety programs are introduced by construction firms. A questionnaire survey study was conducted to highlight the influence of the Construction Safety Factors on safety program implementation. The input from the questionnaire survey was analyzed by using AIM (Average Index Method and rank correlation test was conducted between different groups of respondents to measure the association between different groups of respondent. The finding of this study highlighted that management support is the critical factor for implementing the safety program on projects. From statistical test, it is concluded that all respondent groups were strongly in the favor of management support factor as CSF (Critical Success Factor. The findings of this study were validated on selected case studies. Results of the case studies will help to know the effect of the factors on implementing safety programs during the execution stage.

    Full Text Available The article analyzes the heteronomy of academic work in Brazil, particularly public higher education. It discusses the meaning of rupture of the national-developmentalist project by the irruption of the corporate-military coup and the combined process of coercion (AI-5/1968 and Decree 477/1969 and of the subordination of research and postgraduate studies to monopolistic capitalism in counterreformation of 1968, through programs to encourage science and technology geared to the concerns of bourgeois fractions that sustained the regime. Facing the processes of dispossession and alienation of academic work in the dictatorship, the study examines the organization of teaching movement, its first strikes and the centrality given to career university project of ANDES. Finally, it presents as deepening the dependent capitalism over the last three decades reoriented public university and private higher education, indicating effects on teaching work and the struggles for affirmation of the public sphere as antimercantile.

    1991-01-01

    In September 1990, Martin Marietta Energy Systems (Energy Systems) discovered high levels of Cesium-137 ( 137 Cs) in surface sedimenus near the mouth of White Oak Creek Embayment (WOCE). White Oak Creek (WOC) receives surface water drainage from Oak Ridge National Laboratory. Since this discovery, the Department of Energy (DOE) and Energy Systems have pursued actions designed to stabilize the contaminated WOCE sediments under provisions of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), and the implementing regulations in the National Contingency Plan (NCP) (40 CFR Part 300), as a time-critical removal action. By definition, a time-critical removal is an action where onsite activities are initiated within six months of the determination that a removal action is appropriate. Time-critical removal actions allow comparatively rapid mobilization to protect human health and the environment without going through the lengthy and extensive CERCLA Remedial Investigation/Feasibility Study/Record of Decision process. Many aspects of the project, in terms of compliance with the substantive requirements of the NCP and ARARs, have exceeded the regulatory requirements, despite the fact that there is no apparent authority on conducting removal actions at Federal facilities. Much of the interpretation of the NCP was groundbreaking in nature for both EPA and DOE. 4 refs., 2 figs

  17. STRATEGIC MAPS AND CRITICAL FACTORS FOR PROJECT MANAGEMENT MATURITY: A PROPOSAL

    Directory of Open Access Journals (Sweden)

    Sady Darcy Silva Junior

    2010-06-01

    Full Text Available Project Management (PM and Strategic Management (SM are two subjects of growing importance in the corporate environment which are normally considered in isolation. One way of integrating these two concepts might be via the concept of project management maturity (Westphal et al., 2008. Rabechini and Pessoa (2005 state that to obtain project management maturity, it is necessary to achieve success in a number of critical factors which include organizational culture and structure, as well as sponsorship at both tactical and strategic levels (Silva et al., 2008. Another way of achieving this connection is by using Balanced Scorecard (BSC as an auxiliary tool to integrate between projects and organizational strategy (Brock et al., 2003. The original developers of the BSC, Kaplan e Norton, subsequently developed the concept of strategy mapping, which they affirm "represents the missing link between the formulation and the execution of the strategy" (Kaplan e Norton, 2004. This paper proposes a strategy map identifying critical factors for attaining project management maturity. To formulate the map, we used a qualitative, exploratory approach oriented by Project Management theory and strategy mapping. We first identified 13 critical factors, then developed a strategy map, which was evaluated by six specialists (three in SM area and three in PM area.The results suggest links between strategic mapping nad critical factors in project management. It also contributes to both areas independently. Specifically, the study identifies critical factors for project management maturity while demonstrating the applicability of strategic mapping techniques to Balanced Scorecard concepts.

    Objectives To assess critical incident exposure among prehospital emergency services personnel in the developing world context of South Africa; and to assess associated mental health consequences. Methods We recruited a representative sample from emergency services in the Western Cape Province, South Africa, to participate in this cross sectional epidemiological study. Questionnaires covered critical incident exposure, general psychopathology, risky alcohol use, symptoms of post‐traumatic stress disorder (PTSD), and psychological and physical aggression between co‐workers. Open ended questions addressed additional stressors. Results Critical incident exposure and rates of general psychopathology were higher than in studies in the developed world. Exposure to critical incidents was associated with general psychopathology, symptoms of PTSD, and with aggression between co‐workers, but not with alcohol use. Ambulance, fire, and sea rescue services had lower general psychopathology scores than traffic police. The sea rescue service also scored lower than traffic police on PTSD and psychological aggression. The defence force had higher rates of exposure to physical assault, and in ambulance services, younger staff were more vulnerable to assault. Women had higher rates of general psychopathology and of exposure to psychological aggression. Other stressors identified included death notification, working conditions, and organisational problems. Conclusions Service organisations should be alert to the possibility that their personnel are experiencing work ‐related mental health and behavioural problems, and should provide appropriate support. Attention should also be given to organisational issues that may add to the stress of incidents. Workplace programmes should support vulnerable groups, and address death notification and appropriate expression of anger. PMID:16498167

    Study on the critical paths for the schedule control of nuclear power projects has been performed for reactor M310, based on the experiences from Daya Bay project and Ling Ao project. The study shows that the critical paths for the nuclear power project are from NI civil work, NI erection, commissioning of single systems directly serving the CFT to the joint-test. For NI civil work, the critical path is the main civil work of the reactor building, pre-stressing, handover of rooms for important areas, and key CW-erection interfaces; there are four critical paths for NI erection; For startup, two stages can be identified: commissioning of 16 single systems directly serving the CFT and joint-test.

    1990-01-01

    Fundamental changes are occurring in the capital and project development markets both domestically and internationally. In the United States, the capital market has undergone dramatic changes recently, characterized by clubbed debt structures, uncertain pricing spreads, and declining leverage ratios. In response, project sponsors and their investment bankers have created innovative debt and equity structures to attract investors while at the same time minimizing project risk and preserving the flexibility for the project to operate optimally. The structure of a project financing, either U.S. or international, will vary depending on (1) the differing project management/control concerns, financial goals and risk profiles of the developer, equipment and fuel suppliers, bank lenders and equity sources, (2) regulatory issues, such as compliance with the Public Utility Holding Company Act (PUHCA) in the U.S. and similar national utility legislation in the host foreign country, and (3) the tax implications of a given structure to the project owner, lender, and equity supplier. In response to these investor-specific goals and/or constraints, various forms of project structures have been developed. The focus of this paper is on legal and business issues which arise in international project finance, using U.S.project finance as a model that expresses the risk profile that U.S. financial institutions are accustomed to and overlaying the unique risks that are added to project financing which are international in nature

    2016-05-15

    Integrated Project Delivery (IPD) is defined as that people, systems, business structures, and practices of key stakeholders are incorporated into a single-team, with a single process, which executes a project in a way of optimizing the project's outcome, increasing values delivered to the end user, reducing waste, and maximizing efficiency throughout the phases of engineering to construction. The researcher had carried out literature review in terms of IPD to identify major characteristics of IPD which are presented in the following section and had compared such characteristics against peculiarities of nuclear power plant (NPP) construction projects in order to shed light on obstacles in possible application of IPD method to domestic NPP construction projects in the coming days. In this research, three (3) major characteristics of IPD were identified: 1) key stakeholders signing one balanced contract, forming de facto one body, sharing risk and reward 2) an integrated project team being formed in the early stage of a project and providing input to minimize time and cost loss from rework downstream 3) team members co-locating, having open and direct communication, making decisions on time, and pursuing the success of the project itself.

    Most action to address contemporary complex challenges, including the urgent issues of global sustainability, occurs piecemeal and without meaningful guidance from leading complex change knowledge and methods. The potential benefit of using such knowledge is greater efficacy of effort and investment. However, this knowledge and its associated tools and methods are under-utilized because understanding about them is low, fragmented between diverse knowledge traditions, and often requires shifts in mindsets and skills from expert-led to participant-based action. We have been engaged in diverse action-oriented research efforts in Large System Change for sustainability. For us, "large" systems can be characterized as large-scale systems - up to global - with many components, of many kinds (physical, biological, institutional, cultural/conceptual), operating at multiple levels, driven by multiple forces, and presenting major challenges for people involved. We see change of such systems as complex challenges, in contrast with simple or complicated problems, or chaotic situations. In other words, issues and sub-systems have unclear boundaries, interact with each other, and are often contradictory; dynamics are non-linear; issues are not "controllable", and "solutions" are "emergent" and often paradoxical. Since choices are opportunity-, power- and value-driven, these social, institutional and cultural factors need to be made explicit in any actionable theory of change. Our emerging network is sharing and building a knowledge base of experience, heuristics, and theories of change from multiple disciplines and practice domains. We will present our views on focal issues for the development of the field of large system change, which include processes of goal-setting and alignment; leverage of systemic transitions and transformation; and the role of choice in influencing critical change processes, when only some sub-systems or levels of the system behave in purposeful ways

    Full Text Available National Health Insurance (NHI in Korea has covered Korean medicine (KM services including acupuncture, moxibustion, cupping, and herbal preparations since 1987, which represents the first time that an entire traditional medicine system was insured by an NHI scheme anywhere in the world. This nationwide insurance coverage led to a rapid increase in the use of KM, and the KM community became one of the main interest groups in the Korean healthcare system. However, due to the public's safety concern of and the stagnancy in demand for KM services, KM has been facing new challenges. This paper presents a brief history and the current structure of KM health insurance, and describes the critical issues related to KM insurance for in-depth understanding of the present situation.

  8. Crossing alone the Mediterranean sea. Some critical issues about unaccompanied minors in Europe

    Directory of Open Access Journals (Sweden)

    Giovanni Giulio Valtolina

    Full Text Available Abstract Despite the increasing social impact of unaccompanied migrant minors (UAMs in many European Union (EU member states, EU regulations on UAMs are still inadequate and the necessary protection measures are thus insufficient. More specifically, the “best interest of the child”, stated in a large number of international documents, may not be properly guaranteed. In addition, there is often a discrepancy between the rights of migrant children, according to the international legislation, and the actual protection they receive. Moreover, despite the declared aim of reaching a common standard of reception and inclusion, policies and practices across Europe are still very different. The paper attempts to highlight and discuss some critical issues regarding UAMs in Europe. Over and beyond the need for the EU to develop a common framework, greater efforts should be made in order to improve inclusion of UAMs, especially to ensure the management of the phenomenon beyond the current emergency.

Focused in this context, the objective of this paper is to investigate and describe how the culture issue can affect the anagement of global project teams. It is a qualitative, descriptive study conducted in a large multinational company in the automotive sector. The results of this research show that cultural issues can influence both positively and negatively the management of project global teams and the managers of these projects have to deal with several management challenges that require the adoption of certain ways of dealing with culture impacts in managing their teams to minimize potential problems in this context.

    Bali Island in Indonesia is a world-famous resort area, and the beaches composed of coral sand are one of the most important resources for tourism. However, serious beach erosion has occurred since the 1970s owing to the tourism development along the coastal areas. To recover previous natural sandy beaches, Bali Beach Conservation Project was undertaken by the Indonesian Government as the ODA project financed by Japan. Three seriously eroded beaches (Sanur, Nusa Dua and Kuta) with a total len...

    Survivors of critical illness commonly experience neuromuscular abnormalities, including muscle weakness known as ICU-acquired weakness (ICU-AW). ICU-AW is associated with delayed weaning from mechanical ventilation, extended ICU and hospital stays, more healthcare-related hospital costs, a higher risk of death, and impaired physical functioning and quality of life in the months after ICU admission. These observations speak to the importance of developing new strategies to aid in the physical recovery of acute respiratory failure patients. We posit that to maintain optimal muscle mass, strength and physical function, the combination of nutrition and exercise may have the greatest impact on physical recovery of survivors of critical illness. Randomized trials testing this and related hypotheses are needed. We discussed key methodological issues and proposed a common evaluation framework to stimulate work in this area and standardize our approach to outcome assessments across future studies.

  14. References to Human Rights in Codes of Ethics for Psychologists: Critical Issues and Recommendations. Part 1

    Directory of Open Access Journals (Sweden)

    Жанель Готье

    2018-12-01

    Full Text Available There are codes of ethics in psychology that explicitly refer to human rights. There are also psychologists interested in the protection and promotion of human rights who are calling for the explicit inclusion of references to human rights in all psychology ethics codes. Yet, references to human rights in ethics documents have rarely been the focus of attention in psychological ethics. This article represents the first part of a two-part article series focusing on critical issues associated with the inclusion of references to human rights in the ethical codes of psychologists, and recommendations about how psychological ethics and the human rights movement can work together in serving humanity. The first part of the article series examines issues pertaining to the interpretation of references to human rights in codes of ethics for psychologists, and the justifications for including these references in psychological ethics codes. The second part of the article series examines how the Universal Declaration of Ethical Principles for Psychologists can be used to extend or supplement codes of ethics in psychology, how ethical principles and human rights differ and complement each other, and how psychological ethics and the human rights movement can work together in serving humanity and improving the welfare of both persons and peoples.

  15. The neurosurgical workforce in North America: a critical review of gender issues.

    Woodrow, Sarah I; Gilmer-Hill, Holly; Rutka, James T

    2006-10-01

    The role of women in Western society has changed dramatically in the past several decades. Despite this, many gender disparities still exist for professionals in the health care sector. In neurosurgery, a disproportionately small percentage of the workforce in the United States and Canada is female. These figures are lower than most reported in other medical specialties. This review critically examines factors that may be influencing women's ability to advance in demanding subspecialties such as neurosurgery. The literature on women in medicine, and surgery in particular, were reviewed to identify different issues facing women currently in practice in neurosurgery. In addition, the concerns of prospective trainees were examined. There remain many challenges for women entering neurosurgery, including unique lifestyle concerns, limited mentorship, out-dated career programs, and deep-seeded societal beliefs. Discrimination and harassment are also contributing factors. If neurosurgery is to continue to progress as a subspecialty, the issue of gender inequality needs to be scrutinized more closely. Innovative programs must be developed to meet the needs of current female faculty members and to ensure attracting the brightest individuals of both genders into a career in neurosurgery.

  16. Critical Design Issues of Tokamak Cooling Water System of ITER's Fusion Reactor

    Kim, Seokho H.; Berry, Jan

    2011-01-01

    U.S. ITER is responsible for the design, engineering, and procurement of the Tokamak Cooling Water System (TCWS). The TCWS transfers heat generated in the Tokamak to cooling water during nominal pulsed operation 850 MW at up to 150 C and 4.2 MPa water pressure. This water contains radionuclides because impurities (e.g., tritium) diffuse from in-vessel components and the vacuum vessel by water baking at 200 240 C at up to 4.4MPa, and corrosion products become activated by neutron bombardment. The system is designated as safety important class (SIC) and will be fabricated to comply with the French Order concerning nuclear pressure equipment (December 2005) and the EU Pressure Equipment Directive using ASME Section VIII, Div 2 design codes. The complexity of the TCWS design and fabrication presents unique challenges. Conceptual design of this one-of-a-kind cooling system has been completed with several issues that need to be resolved to move to next stage of the design. Those issues include flow balancing between over hundreds of branch pipelines in parallel to supply cooling water to blankets, determination of optimum flow velocity while minimizing the potential for cavitation damage, design for freezing protection for cooling water flowing through cryostat (freezing) environment, requirements for high-energy piping design, and electromagnetic impact to piping and components. Although the TCWS consists of standard commercial components such as piping with valves and fittings, heat exchangers, and pumps, complex requirements present interesting design challenges. This paper presents a brief description of TCWS conceptual design and critical design issues that need to be resolved.

    This research aimed to investigate the changes in ethical issues in everyday clinical practice recognized by critical care nurses during two observation periods. We conducted a retrospective analysis of data obtained by prospective questionnaire surveys of nurses in the intensive care units (ICU) of a tertiary university-affiliated hospital in Seoul, Korea. Data were collected prospectively during two different periods, February 2002-January 2003 (Period 1) and August 2011-July 2012 (Period 2). Significantly fewer cases with ethical issues were reported in Period 2 than in Period 1 (89 cases [2.1%] of 4,291 ICU admissions vs. 51 [0.5%] of 9,302 ICU admissions, respectively; P ethical issues in both Periods occurred in MICU. The major source of ethical issues in Periods 1 and 2 was behavior-related. Among behaviorrelated issues, inappropriate healthcare professional behavior was predominant in both periods and mainly involved resident physicians. Ethical issue numbers regarding end-oflife (EOL) care significantly decreased in the proportion with respect to ethical issues during Period 2 (P = 0.044). In conclusion, the decreased incidence of cases with identified ethical issues in Period 2 might be associated with ethical enhancement related with EOL and improvements in the ICU care environment of the studied hospital. However, behaviorrelated issues involving resident physicians represent a considerable proportion of ethical issues encountered by critical care nurses. A systemic approach to solve behavior-related issues of resident physicians seems to be required to enhance an ethical environment in the studied ICU.

    The World Health Organisation has advocated for comprehensive primary care teams, which include family physicians. However, despite (or because of) severe doctor shortages in Africa, there is insufficient clarity on the role of the family physician in the primary health care team. Instead there is a trend towards task shifting without thought for teamwork, which runs the risk of dangerous oversimplification. It is not clear how African leaders understand the challenges of implementing family medicine, especially in human resource terms. This study, therefore, sought to explore the views of academic and government leaders on critical human resource issues for implementation of family medicine in Africa. In this qualitative study, key academic and government leaders were purposively selected from sixteen African countries. In-depth interviews were conducted using an interview guide. All interviews were audio-recorded, transcribed and thematically analysed. There were 27 interviews conducted with 16 government and 11 academic leaders in nine Sub-Saharan African countries: Botswana, Democratic Republic of Congo, Ghana, Kenya, Malawi, Nigeria, Rwanda, South Africa and Uganda. Respondents spoke about: educating doctors in family medicine suited to Africa, including procedural skills and holistic care, to address the difficulty of recruiting and retaining doctors in rural and underserved areas; planning for primary health care teams, including family physicians; new supervisory models in primary health care; and general human resource management issues. Important milestones in African health care fail to specifically address the human resource issues of integrated primary health care teamwork that includes family physicians. Leaders interviewed in this study, however, proposed organising the district health system with a strong embrace of family medicine in Africa, especially with regard to providing clinical leadership in team-based primary health care. Whilst these

    In the spring of 2014 Washington University will present one of the first courses, entitled 'Critical Earth Issues,' in a new experiment in online education to be carried out by a consortium of Universities working with the production company 2U. The consortium, consisting of Washington University in St. Louis, Boston College, Brandeis University, Emory University, Northwestern University, the University of North Carolina at Chapel Hill, and the University of Notre Dame, will all offer courses that can be taken by each other's students. In addition, three affiliate institutions so far (Baylor University, Southern Methodist University, and Temple University) have agree to allow their students to take online courses from this consortium, and transfer credit will be granted from the consortium institution teaching a particular course to students from other institutions as well. A total of eleven courses from the seven consortium schools are being taught in the fall of 2013. 'Critical Earth Issues,' to be taught the next spring, will be the first geoscience course taught. The structure of the course will be very different from traditional MOOCs. Half of the course (80 minutes per week) will be asynchronous and produced in advance by the company 2U. This is designed to take the place of the lecture component of a class, but it can take a variety of forms. While there are traditional lecture segments and filmed demos, these are also broken up by assignments for the students in order to make the 'lecture' segment more interactive. Sometimes the students will have to answer short or long questions before they can go on to the next part of the asynchronous material. Students can only get to the assignment at the end if they work their way through all the produced and interactive segments. This material will often also prompt them to upload an 'assignment,' such as uploading photos of different rocks that are used for the buildings at their host institution (to be shared

    The GETSI project, funded by NSF TUES, is developing and disseminating teaching and learning materials that feature geodesy data applied to critical societal issues such as climate change, water resource management, and natural hazards (serc.carleton.edu/getsi). It is collaborative between UNAVCO (NSF's geodetic facility), Mt San Antonio College, and Indiana University. GETSI was initiated after requests by geoscience faculty for geodetic teaching resources for introductory and majors-level students. Full modules take two weeks but module subsets can also be used. Modules are developed and tested by two co-authors and also tested in a third classroom. GETSI is working in partnership with the Science Education Resource Center's (SERC) InTeGrate project on the development, assessment, and dissemination to ensure compatibility with the growing number of resources for geoscience education. Two GETSI modules are being published in October 2015. "Ice mass and sea level changes" includes geodetic data from GRACE, satellite altimetry, and GPS time series. "Imaging Active Tectonics" has students analyzing InSAR and LiDAR data to assess infrastructure earthquake vulnerability. Another three modules are in testing during fall 2015 and will be published in 2016. "Surface process hazards" investigates mass wasting hazard and risk using LiDAR data. "Water resources and geodesy" uses GRACE, vertical GPS, and reflection GPS data to have students investigating droughts in California and the High Great Plains. "GPS, strain, and earthquakes" helps students learn about infinitesimal and coseismic strain through analysis of horizontal GPS data and includes an extension module on the Napa 2014 earthquake. In addition to teaching resources, the GETSI project is compiling recommendations on successful development of geodesy curricula. The chief recommendations so far are the critical importance of including scientific experts in the authorship team and investing significant resources in

  2. Critical scientific issues in the demonstration of WIPP compliance with EPA repository standards

    1997-01-01

    The Department of Energy submitted a Compliance Certification Application for the Waste Isolation Pilot Plant to the Environmental Protection Agency (EPA) in October, 1996. A critical part of this application was a Performance Assessment which predicts the cumulative radioactive release to the accessible environment over a time period of 10,000 years. Comparison of this predicted release to the EPA standard shows a comfortable margin of compliance. The scientific understanding that was critical to developing this assessment spans a broad range of geotechnical disciplines, and required a thorough understanding of the site's geology and hydrology. Evaluation of the geologic processes which are active in the site region establishes that there will be no natural breach of site integrity for millions of years, far longer than the 10,000 year regulatory period. Inadvertent human intrusion is, therefore, the only credible scenario to lead to potential radioactive release to the accessible environment. To substantiate this conclusion and to quantify these potential releases from human intrusion, it has been necessary to develop an understanding of the following processes: (1) salt creep and shaft seal efficacy; (2) gas generation from organic decomposition of waste materials and anoxic corrosion of metals in the waste and waste packages; (3) solubilities for actinides in brine; (4) fluid flow in Salado formation rocks, and (5) hydrologic transport of actinides in the overlying dolomite aquifers. Other issues which had to be evaluated to allow definition of breach scenarios were brine reservoir occurrences and their associated reservoir parameters, consequences of mining over the repository, and drilling for natural resources in the vicinity of the repository. Results of all these studies will be briefly summarized in this paper

    Domestic abuse is increasingly recognised as a serious, worldwide public health concern. There is a significant body of literature regarding domestic abuse, but little is known about health professionals' beliefs about domestic abuse disclosure. In addition, the intersection between health professionals' beliefs and abused women's views remains uninvestigated. We report on a two-phase, qualitative study using Critical Incident Technique (CIT) that aimed to explore community health professionals' beliefs about domestic abuse and the issue of disclosure. We investigated this from the perspectives of both health professionals and abused women. The study took place in Scotland during 2011. The study was informed theoretically by the Common Sense Model of Self-Regulation of Health and Illness (CSM). This model is typically used in disease-orientated research. In our innovative use, however, CSM was used to study the social phenomenon, domestic abuse. The study involved semi-structured, individual CIT interviews with health professionals and focus groups with women who had experienced domestic abuse. Twenty-nine health professionals (Midwives, Health Visitors and General Practitioners) participated in the first phase of the study. In the second phase, three focus groups were conducted with a total of 14 women. Data were analysed using a combination of an inductive classification and framework analysis. Findings highlight the points of convergence and divergence between abused women's and health professionals' beliefs about abuse. Although there was some agreement, they do not always share the same views. For example, women want to be asked about abuse, but many health professionals do not feel confident or comfortable discussing the issue. Overall, the study shows the dynamic interaction between women's and health professionals' beliefs about domestic abuse and readiness to discuss and respond to it. Understanding these complex dynamics assists in the employment of

    There is a growing literature on news media representations of alcohol-related issues. However, current scholarship has neglected critical political economic frameworks to interpret media coverage of alcohol. This paper presents such a framework that conceives of news organisations as corporations that share the values and interests of political and economic elites. The media are thus expected to present viewpoints that are more aligned with the alcohol industry than the scientific consensus on public health policy would warrant. The media are also expected, but to a lesser extent, to present a certain amount of support for public health perspectives because these are supported by a few socioeconomic elite groups (the medical professions, progressive politicians). The case of Ireland from 2012 to 2017 illustrates the framework empirically. Four main newspapers' coverage of the Public Health (Alcohol) Bill and related policies is examined. Results show that, overall, 44.0% of articles support public health measures and 56.0% are opposed or remain neutral. It is argued that the media are not strong proponents of public health for multiple reasons: there are more articles opposed to or neutral toward public health measures than supporting them; the number of supportive articles remains relatively small and there are still many pieces presenting drinks industry views; there are virtually no calls in the media for stronger measures; supportive coverage is partially explained by the pub owners lobby's support for minimum unit pricing; the media often downplay or ignore the negative consequences of alcohol, such as its role in accidents; many news articles normalise drinking and promote events sponsored by the industry; there is not a single Irish journalist covering alcohol issues systematically; and other policy issues that are prioritised by elites receive multiple times more media coverage than public health measures. In short, the media reflect the views of the

  11. Human Biomonitoring of Engineered Nanoparticles: An Appraisal of Critical Issues and Potential Biomarkers

    Directory of Open Access Journals (Sweden)

    Enrico Bergamaschi

    2012-01-01

    Full Text Available The present paper deals with the applicability of biological monitoring to the assessment of exposure and possible effects deriving from exposure to engineered nanomaterials (NM. After establishing a conceptual framework in which human biomonitoring should be placed, the paper reviews the critical issues related to the unusual properties of NM affecting the implementation of biomonitoring activities for this new class of chemicals. Relying on the recent advances in the toxicogenomic, it is possible to assess whether specific biological pathways are activated or perturbed by specific NM. However, to evaluate if quantitative changes in these biomarkers can be used as indicators or predictors for toxicity in humans, validation on well characterised groups of exposed people is needed. At present, it appears more pragmatic to evolve NM-associated biomarker identification considering relevant biological responses found in environmental and occupational studies and assessing the early events associated with exposure to these NM. The battery of biochemical markers includes soluble molecules, antioxidant capacity, peroxidated lipids and carbonyl groups in serum proteins as a biomarkers of systemic inflammation and vascular adhesion molecules to assess endothelial activation/damage. Abnormalities in exhaled breath condensate chemistry reflecting intrinsic changes in the airway lining fluid and lung inflammation seem promising tools suitable for BM studies and are broadly discussed.

    This is a critical review on research conducted in the field of pulmonary delivery of liposomes. Issues relating to the mechanism of nebulisation and liposome composition were appraised and correlated with literature reports of liposome formulations used in clinical trials to understand the role of liposome size and composition on therapeutic outcome. A major highlight was liposome inhalation for the treatment of lung cancers. Many in vivo studies that explored the potential of liposomes as anticancer carrier systems were evaluated, including animal studies and clinical trials. Liposomes can entrap anticancer drugs and localise their action in the lung following pulmonary delivery. The safety of inhaled liposomes incorporating anticancer drugs depends on the anticancer agent used and the amount of drug delivered to the target cancer in the lung. The difficulty of efficient targeting of liposomal anticancer aerosols to the cancerous tissues within the lung may result in low doses reaching the target site. Overall, following the success of liposomes as inhalable carriers in the treatment of lung infections, it is expected that more focus from research and development will be given to designing inhalable liposome carriers for the treatment of other lung diseases, including pulmonary cancers. The successful development of anticancer liposomes for inhalation may depend on the future development of effective aerosolisation devices and better targeted liposomes to maximise the benefit of therapy and reduce the potential for local and systemic adverse effects. © 2016 S.

    From many years now, thanks to the development of modern diving techniques, there has been a rapid spread of diving activities everywhere. In fact, divers are ever more numerous both among the Armed Forces and civilians who dive for work, like fishing, biological research and archeology. The aim of the study was to propose a health protocol for work fitness of professional divers keeping in mind the peculiar work activity, existing Italian legislation that is almost out of date and the technical and scientific evolution in this occupational field. We performed an analysis of the most frequently occurring diseases among professional divers and of the clinical investigation and imaging techniques used for work fitness assessment of professional divers. From analysis of the health protocol recommended by D.M. 13 January 1979 (Ministerial Decree), that is most used by occupational health physician, several critical issues emerged. Very often the clinical investigation and imaging techniques still used are almost obsolete, ignoring the execution of simple and inexpensive investigations that are more useful for work fitness assessment. Considering the out-dated legislation concerning diving disciplines, it is necessary to draw up a common health protocol that takes into account clinical and scientific knowledge and skills acquired in this area. This protocol's aim is to propose a useful tool for occupational health physicians who work in this sector.

  14. SEGMENTATION OF 3D MODELS FOR CULTURAL HERITAGE STRUCTURAL ANALYSIS – SOME CRITICAL ISSUES

    Directory of Open Access Journals (Sweden)

    S. Gonizzi Barsanti

    2017-08-01

    Full Text Available Cultural Heritage documentation and preservation has become a fundamental concern in this historical period. 3D modelling offers a perfect aid to record ancient buildings and artefacts and can be used as a valid starting point for restoration, conservation and structural analysis, which can be performed by using Finite Element Methods (FEA. The models derived from reality-based techniques, made up of the exterior surfaces of the objects captured at high resolution, are - for this reason - made of millions of polygons. Such meshes are not directly usable in structural analysis packages and need to be properly pre-processed in order to be transformed in volumetric meshes suitable for FEA. In addition, dealing with ancient objects, a proper segmentation of 3D volumetric models is needed to analyse the behaviour of the structure with the most suitable level of detail for the different sections of the structure under analysis. Segmentation of 3D models is still an open issue, especially when dealing with ancient, complicated and geometrically complex objects that imply the presence of anomalies and gaps, due to environmental agents such as earthquakes, pollution, wind and rain, or human factors. The aims of this paper is to critically analyse some of the different methodologies and algorithms available to segment a 3D point cloud or a mesh, identifying difficulties and problems by showing examples on different structures.

    Cultural Heritage documentation and preservation has become a fundamental concern in this historical period. 3D modelling offers a perfect aid to record ancient buildings and artefacts and can be used as a valid starting point for restoration, conservation and structural analysis, which can be performed by using Finite Element Methods (FEA). The models derived from reality-based techniques, made up of the exterior surfaces of the objects captured at high resolution, are - for this reason - made of millions of polygons. Such meshes are not directly usable in structural analysis packages and need to be properly pre-processed in order to be transformed in volumetric meshes suitable for FEA. In addition, dealing with ancient objects, a proper segmentation of 3D volumetric models is needed to analyse the behaviour of the structure with the most suitable level of detail for the different sections of the structure under analysis. Segmentation of 3D models is still an open issue, especially when dealing with ancient, complicated and geometrically complex objects that imply the presence of anomalies and gaps, due to environmental agents such as earthquakes, pollution, wind and rain, or human factors. The aims of this paper is to critically analyse some of the different methodologies and algorithms available to segment a 3D point cloud or a mesh, identifying difficulties and problems by showing examples on different structures.

    This work develops a model for design and realisation of profitability's and feasibility studies of a mining project. The model provides the structure of various necessary procedures to establish the feasibility studies and presents a logical system of task sequencing and information circulating between tasks. The specifications of mining projects, particularly their duration, complexity and high costs, necessitate design and realisation of feasibility study bases on the sufficient understanding of task behaviour and the critical path method view. For this purpose, critical paths with the highest frequency of occurrence were studied through several simulations. In addition, the critical tasks and sub tasks with the most probability were identified. The model introduced in this paper can serve as a perfect tool in feasibility study of a mining project. It can also be used as a basis of future development of mining software

    This paper presents the experience on the design and implementation of a user-centered Oncology Information System developed for the Medical Oncology Department at the "Hospital Universitario Virgen de la Victoria", in Málaga, Spain. The project focused on the aspects considered in the literature as critical factors for a successful deployment and usage of a health information system. System usability, adequate technology, integration of clinical routines, real-time statistical analysis of data, information confidentiality and standard protocol-based external interconnection were the key aspects considered. The developed system is based on a web application with a modular and layered architecture accounting for usability, ease of maintenance and further system development. Evaluation of system usability was carried at three and fifteen months after system deployment to analyze the advantages/disadvantages experienced by the end-users. A thorough prior analysis of clinical activities and workflows, the use of the adequate technology, and the availability of data analysis tools will almost guarantee success in the deployment of an Oncology Information System.

    Full Text Available Purpose: The purpose of this paper is to define the relative optimal incentive contract to effectively encourage employees to improve work efficiency while actively implementing innovative behavior. Design/methodology/approach: This paper analyzes a two staged incentive contract coordinated with efficiency and innovation in Critical Chain Project Management using learning real options, based on principle-agent theory. The situational experiment is used to analyze the validity of the basic model. Finding: The two staged incentive scheme is more suitable for employees to create and implement learning real options, which will throw themselves into innovation process efficiently in Critical Chain Project Management. We prove that the combination of tolerance for early failure and reward for long-term success is effective in motivating innovation. Research limitations/implications: We do not include the individual characteristics of uncertain perception, which might affect the consistency of external validity. The basic model and the experiment design need to improve. Practical Implications: The project managers should pay closer attention to early innovation behavior and monitoring feedback of competition time in the implementation of Critical Chain Project Management. Originality/value: The central contribution of this paper is the theoretical and experimental analysis of incentive schemes for innovation in Critical Chain Project Management using the principal-agent theory, to encourage the completion of CCPM methods as well as imitative free-riding on the creative ideas of other members in the team.

    The aim of this document is to present a critical review of issues concerned with the treatment of the biosphere and geosphere-biosphere interface in long-term performance assessment studies for nuclear waste disposal in Sweden. The review covers three main areas of investigation: a review of SKB's plans for undertaking site investigations at candidate locations for the development of a deep geological repository for spent fuel; identification of critical uncertainties associated with SKB's treatment of the geosphere-biosphere interface in recent performance assessments; and a preliminary modelling investigation of the significance of features, events and processes in the near-surface environment in terms of their effect on the accumulation and redistribution of radionuclides at the geosphere-biosphere interface. Overall, SKB's proposals for site investigations are considered to be comprehensive and, if they can be carried out to the specification presented, will constitute a benchmark that other waste management organisations will have to work hard to emulate. The main concern is that expertise for undertaking the investigations and reporting the results could be stretched very thin. The authors have also identified weaknesses in the documentation concerning the collection of evidence for environmental change and on developing scenarios for future environmental change. A fundamental assumption adopted in the renewed assessment of the SFR 1 repository, which is not discussed or justified in any of the documentation that has been reviewed, is that radionuclides enter the water column of the coastal and lake models directly, without passing first through the bed sediments. The modelling study reported herein suggests that SKB's models are robust to range of alternative conceptual descriptions relating to the geosphere-biosphere interface. There are however situations, in which contaminated groundwater is released via sediment rather than directly

    2012-09-01

    Full Text Available Complexity is one of the most important issues influencing success of any construction project and there are literally different studies devoted to detect important factors increasing complexity of projects. During the past few years, there have been growing interests in developing mass construction projects in Iran. The proposed study of this paper uses Delphi technique to find out about important factors as barriers of construction projects in Iran. The results show that among 47 project complexity factors, 19 factors are more important than others are. The study groups different factors into seven categories including environmental, organizational, objectives, tasks, stakeholders, technological, information systems and determines the relative importance of each. In each group, many other sub group activities are determined and they are carefully investigated. The study provides some detailed suggestions on each category to reduce the complexity of construction project.

Ltd, Haiyang, Shandong 265118 (China)

    2010-06-15

    Chinese electric power industry has adopted Build-Operate-Transfer (BOT) approach in a number of projects to alleviate the pressure of sole state-owned investment. The Chinese government has taken enormous efforts to create an environment to facilitate the application of BOT approach in electric power projects. Moreover, the growing attention on the sustainability issues puts the traditional major source of electricity - thermal power project under more strict scrutiny. As a result, various renewable energy projects, particularly the wind power projects have involved private sector funds. Both thermal power and wind power projects via BOT approach have met with a varying degree of success. Therefore, it is imperative to understand the factors contributing towards the success of both types of BOT power projects. Using an extensive literature survey, this paper identifies 31 success factors under 5 categories for Chinese BOT electric power projects. This is followed by a questionnaire survey to exam relative significance of these factors. The results reveal the different levels of significance of success factors for BOT thermal power projects versus wind power projects. Finally, survey results were analyzed to explore the underlying construction and distributions among the identified success factors. This study provides a valuable reference for all involved parties that are interested in developing BOT electric power projects in China. (author)

  9. The corporate impact of addressing social issues: a financial case study of a project in Peru.

    Dabbs, Alan; Bateson, Matthew

    2002-05-01

    Large, multinational resource development projects can affect many aspects, including social, economic and ecological realities, in the regions where they operate. Social and environmental issues that are usually ignored in such projects are increasingly affecting the financial future of multinational corporations in negative ways. In this article, we advance the argument that corporations can successfully manage these issues and that if they choose to view these management efforts as an investment rather than an expense, they may well acquire a competitive advantage over companies that do not. We describe as a case study the Camisea natural gas and condensates development project in Peru, operated by Shell Prospecting and Development Peru (SPDP). Camisea is one of the first projects anywhere in the world to conduct a detailed analysis of key industry-related social issues and the processes, required investment and financial impact of managing them. The Camisea example supports the argument that addressing social and environmental concerns makes financial sense. In present value terms, the benefit of managing these concerns was expected to surpass the cost investment by approximately US$50 million.

    2010-10-15

    The final report for IEA Wind Task 23, Offshore Wind Energy Technology and Deployment, is made up of two separate reports: Subtask 1: Experience with Critical Deployment Issues and Subtask 2: Offshore Code Comparison Collaborative (OC3). The Subtask 1 report included here provides background information and objectives of Task 23. It specifically discusses ecological issues and regulation, electrical system integration and offshore wind, external conditions, and key conclusions for Subtask 1. A comprehensive approach to planning is needed that integrates impacts on ecology, the effects of electrical infrastructure, and the layout of wind farms. Governments, which usually finance ecological research, should disclose results for wide dissemination as they become available. As example the workshop held suggested that documents covering the issues like offshore wind energy legislation, Guidelines for EIAs and SEAs and best practices need to be produced and distributed on a regular basis, as ecological research progresses and experience from the planning and operation of existing wind farms emerges. Research should help strike the balance between optimum regulation and the need to get projects up and running. Such research is needed to increase understanding of offshore wind metrology and its impact on electrical power fluctuations. More work is needed to develop special grid code and standards for offshore. The transient behavior of large cable installations (switching / harmonic/ Behavior and modeling of large HV cable systems) must be better understood. Connection and control systems must be developed for large offshore wind farms. Work is needed to develop the technical architecture of offshore wind grid systems. Public access to measurements (e.g., turbine power output, meteorological masts, buoys) is important, especially for model validation. Determining wake effects is currently the most important challenge in wind engineering. Emphasis should be put into

    ENGLISH ABSTRACT: Manufacturing companies operate in a business environment where incremental growth may be achieved through expansion and renewal of existing plant and facilities. Effective management of the critical success factors of such capital development projects may also provide competitive advantage. These projects tend to be of a brown-field nature, characterised by a significant level of risk arising from the interaction between the project implementation and concurrent operation of the existing physical asset base. So it is vital to understand the factors that influence the success of capital expansion and renewal projects in the brown-field context. Although each project has unique features, there are critical success factors that can be customised for successful outcomes in the brown-field environment. This study identifies five critical success factors applicable to brown-field capital expansion and renewal projects. Managerial focus on the critical factors, and the prospects for successful brown-field projects, are discussed in the paper.

    Irrigation helps in increasing the agricultural yield and the irrigation projects are carried out for the welfare of people. The importance of environment for sustainable development of irrigation projects has been realized. Environmental Impact Assessment is being increasingly used as a tool for appropriate environmental planning. In Pakistan, PEP A (Pakistan Environmental Protection Act),1997 establishes the framework to carry out Environmental Assessment of development projects. Various national and international agencies have developed Environmental Assessment Guidelines and Checklists for systematic evaluation of environmental impacts and their mitigation. The Social and Environmental Management Unit of Punjab Irrigation and Drainage Authority developed checklist for assessment of irrigation projects in 2007. The present study was conducted on three water sector projects namely: Concrete Lining of Dhudi Minor, Improving Nikki Deg Drain System and Rehabilitation of Khanki Barrage. The field verification of social and environmental issues of the projects was carried out according to the checklist of Social and Environmental Management Unit. The most noticeable impacts which were identified include: extended canal closure, emissions and effluents, waste generation and disposal, effect on flora, public health and safety, land acquisition, and social issues. The mitigatory measures proposed: proper project scheduling to minimize the canal closure periods, waste disposal through proper planning, preparation of detailed resettlement action plans and compensation, location of labor camps away from the settlements, avoiding unnecessary cutting of trees, and deployed machinery should be in good working condition. The recommendations of the study are to review and improve the checklists through a gradual and phased process into a more comprehensive social and environmental assessment process; capacity building of all the stake holders; collaboration between different

    This feasibility study provides the technical justification for conclusions about K Basin sludge storage options. The conclusions, solely based on criticality safety considerations, depend on the treatment of the sludge. The two primary conclusions are, (1) untreated sludge must be stored in a critically safe storage tank, and (2) treated sludge (dissolution, precipitation and added neutron absorbers) can be stored in a standard Double Contained Receiver Tank (DCRT) or 241-AW-105 without future restrictions on tank operations from a criticality safety perspective.

    Spangler, M.B.

    1986-07-01

    Prior to the TMI-2 accident on March 28, 1979, four nuclear power plant units that had previously been issued a construction permit were cancelled, principally because of reduced projections of regional power demand. Since that time, an additional 31 units with CPs have been cancelled and eight units deferred. On December 23, 1985 one of the deferred units (Limerick-2) was reactivated and construction resumed. The primary objective of this policy study is to identify the principal issues requiring office-level consideration in the event of reactivation of the construction of one or more of the nuclear power plants falling into two categories: (1) LWR units issued a construction permit whose construction has been cancelled, and (2) LWR units whose construction has been deferred. The study scope is limited to identifying regulatory issues or questions deserving analysis rather than providing, at this time, answers or recommended actions. Five tasks are addressed: a tabulation and discussion of the status of all cancelled and deferred LWR units; and identification of potential safety and environmental issues; an identification of regulatory or policy issues and needed information to determine the desirability of revising certain rules and policies; and identification of regulatory options and decision criteria; and an identification of decision considerations in determining staff requirements and organizational coordination of LWR reactivation policy and implementation efforts. 41 refs

    Full Text Available Lake Orta, located in Piedmont, northwestern Italy, has been severely affected by industrial pollution since the 1930s. A successful liming intervention, performed in 1988-1990, returned pH levels in the lake to neutrality, and accelerated the reduction of aqueous trace metal concentrations. In this paper, we present an update knowledge of the chemical status of Lake Orta, focusing on the data collected from 1990 to 2014. In this period we sampled the lake at its deepest point (Qualba station, on a monthly (1990-2000 or seasonal (since 2001 basis. Samples were collected at nine depths through the water column, and analyzed for pH, conductivity, alkalinity, major ions, nutrients, and trace metals. Collectively, these data allowed us to evaluate the long-term response of the lake to the restoration treatment, with particular regard to its acid-base status; they also provided insights into emerging or potential critical issues, including eutrophication and re-suspension of trace metals that still linger in the lake. Furthermore, the evaluation of the present chemical condition of the lake is a precondition for any successive restoration measure, such as fish introduction. The recent data confirmed the lake’s water quality has recovered, i.e. returned to a pre-pollution chemical state. Lake water values of pH and concentrations of ammonium, sulphate and base cations have stabilized. Alkalinity and nitrate concentrations are also expected to reach stable level in the next few years. Levels of nitrate, reactive silica, and phosphorus compounds are now regulated by algal uptake, providing indirect evidence of a partial biological recovery. For instance, both the inter-annual average decline and the reappearance of a seasonal signal in silica confirmed the presence of a stable diatom community. The lake is presently oligotrophic, and concentrations of both N and P compounds are steady and low throughout the year. However, a monthly check of nutrient

    Since the International Conference on Nuclear Criticality Safety (ICNC) 2007, the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and the International Reactor Physics Experiment Evaluation Project (IRPhEP) have continued to expand their efforts and broaden their scope. Eighteen countries participated on the ICSBEP in 2007. Now, there are 20, with recent contributions from Sweden and Argentina. The IRPhEP has also expanded from eight contributing countries in 2007 to 16 in 2011. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Criticality Safety Benchmark Experiments1' have increased from 442 evaluations (38000 pages), containing benchmark specifications for 3955 critical or subcritical configurations to 516 evaluations (nearly 55000 pages), containing benchmark specifications for 4405 critical or subcritical configurations in the 2010 Edition of the ICSBEP Handbook. The contents of the Handbook have also increased from 21 to 24 criticality-alarm-placement/shielding configurations with multiple dose points for each, and from 20 to 200 configurations categorized as fundamental physics measurements relevant to criticality safety applications. Approximately 25 new evaluations and 150 additional configurations are expected to be added to the 2011 edition of the Handbook. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Reactor Physics Benchmark Experiments2' have increased from 16 different experimental series that were performed at 12 different reactor facilities to 53 experimental series that were performed at 30 different reactor facilities in the 2011 edition of the Handbook. Considerable effort has also been made to improve the functionality of the searchable database, DICE (Database for the International Criticality Benchmark Evaluation Project) and verify the accuracy of the data contained therein. DICE will be discussed in separate papers at ICNC 2011. The status of the

    Full Text Available The sport for development and peace (SDP sector is made up of various development-focused policies and programs that seek to engage, stabilise, empower and create social and economic change. SDP projects, most often run by non-governmental organisations (NGOs, have been implemented in regions enduring physical conflicts, health pandemics, major gender divisions and other social crises that have a great impact on youth. In this context, sport has been accorded the difficult task of facilitating greater access for marginal, vulnerable or community groups whilst positively contributing to the attainment of diverse development objectives. While the ‘where’ and ‘why’ of SDP has been largely accounted for, the attention in this article is on the ‘who’ of SDP in relation to the notion of inclusion. Drawing on extensive research conducted in Jamaica, Kosovo, Rwanda and Sri Lanka, the idea of SDP as an inclusionary practice is critically investigated. While SDP may ‘give voice’ to participants, especially to individuals with athletic ability or sporting interests, the extent to which this creates social contexts that are fundamentally inclusive remains open to discussion. In this sense, while targeting populations, groups or individuals remains an attractive strategy to achieve specific goals, for example youth empowerment or gender equality, empirical assessments complicate the presumption that SDP programming leads to inclusion, particularly at a larger societal level. The article considers a matrix of inclusion criteria, potential outcomes, and the tensions arising between targeted SDP programming and the often-exclusionary dimensions of sport more broadly, with a focus on youth and gender issues.

    Full Text Available This research aims to investigate effect of learning using natural product mini project laboratory on students’ critical thinking skills. The research was conducted on sixth semester of 59 students of chemistry and chemistry education program from one of the state universities in West Nusa Tenggara, Indonesia in 2012/2013. This research revealed class where the student learn using natural product mini project laboratory had more critical thinking skills than those using verification laboratory. The average n-gain of critical thinking skills for experiment class was 0.58 while for the control class was 0.37. The highest n-gain in the experiment class was 0.70 for “deciding on an action (selecting criteria to judge possible solutions indicators”, while the smallest n-gain was 0.47 for “the making and judging value of judgments (balancing, weighing, and deciding indicators. We concluded that the natural product mini project laboratory was better than verification laboratory in improving the students’ critical thinking skills.

    Full Text Available Throughout the library community examples can be found of development projects evolving into mission critical components within an organization's workflow. How these projects make that move is unique and varied, but little discussion has been had about how these projects impact their developers and the project community. What responsibilities does a developer have to ensure the long-term viability of their project? Does simply freeing the code meet those long-term responsibilities, or is there an implied commitment to provide long-term "care and feeding" to project communities built up over time? Code4Lib represents a group of developers consistently looking to build the next big thing, I'd like to step back and look at some of my own experiences related to the long-term impacts that come with developing successful projects and communities, and try to provide library developers food for thought as they consider their own ongoing responsibilities to their projects and user communities.

  9. Examining the Interrelationship among Critical Success Factors of Public Private Partnership Infrastructure Projects

    Full Text Available Examining the interrelationships among critical success factors (CSFs for public private partnership (PPP projects is of importance for improving PPP project performance and maintaining the sustainability of PPP project implementation. Previous studies mostly focused on the identification of the CSFs for PPP projects; limited studies investigated the interrelationships among CSFs. Hence, the research objectives are (a to determine the interrelationships among CSFs of PPP projects taking into account the public and (b to identify influence paths contributing to take advantage of CSFs in the process of PPP implementation. A literature review and expert interviews were adopted to construct the CSFs framework; nine hypotheses were constructed and tested by the structural equation modelling (SEM based on the data collected from a questionnaire survey. This research reveals that the relationship between public and private partners is the leader-follower relationship, not the partnership relationship, in PPP projects, indicating that the responsibilities, power or resources existing among partners are very unequal. It also highlights that public involvement has a negative effect on the process of service provisions, and costs and risks exist in the process of public involvement in PPP projects. The determined interrelationships among CSFs will contribute to the sustainability and success of a PPP project.

    The greatest threat to human well-being in this century is climate change and related global issues. We examined the effectiveness of the Modified Instrumentalism in Occupational Therapy model as a framework for facilitating occupational behaviour change to address climate change and related issues. Eleven individuals participated in this mixed-methods single-subject-design study. Data were gathered using the Modified Assessment and Intervention Instrument for Instrumentalism in Occupational Therapy and Daily Occupational Inventories. Quantitative data were analyzed using two- and three-standard deviation band methods. Qualitative data were analyzed using heuristic phenomenological procedures. Occupational performance changed for five participants. Participants' feelings shifted from frustration and helplessness to empowerment and a desire for action. They felt empowered to find occupation-based solutions to the global issues. Occupation-based interventions that increase personal awareness of the connection between occupational performance and global issues could empower people to be agents for action to ameliorate the issues.

    2016-01-01

    Despite the prevalence of Small Satellites in recent years, the systems flown to date have very limited propulsion capability. SmallSats are typically secondary payloads and have significant constraints for volume, mass, and power in addition to limitations on the use of hazardous propellants or stored energy (i.e. high pressure vessels). These constraints limit the options for SmallSat maneuverability. NASA's Space Technology Mission Directorate approved the iodine Satellite flight project for a rapid demonstration of iodine Hall thruster technology in a 12U configuration under the Small Spacecraft Technology Program. The project formally began in FY15 as a partnership between NASA MSFC, NASA GRC, and Busek Co, Inc., with the Air Force supporting the propulsion technology maturation. The team is in final preparation of the Critical Design Review prior to initiating the fabrication and integration phase of the project. The iSat project is on schedule for a launch opportunity in November 2017.

  15. Increasing the Value of Research: A Comparison of the Literature on Critical Success Factors for Projects, IT Projects and Enterprise Resource Planning Projects

    Directory of Open Access Journals (Sweden)

    Annie Maddison Warren

    2016-11-01

    Full Text Available Since the beginning of modern project management in the 1960s, academic researchers have sought to identify a definitive list of Critical Success Factors (CSFs, the key things that project managers must get right in order to deliver a successful product. With the advent of Information Technology (IT projects and, more recently, projects to deliver Enterprise Resource Planning (ERP systems, attention has turned to identifying definitive lists of CSFs for these more specific project types. The purpose of this paper is to take stock of this research effort by examining how thinking about each type of project has evolved over time, before producing a consolidated list of CSFs for each as a basis for comparison. This process reveals a high degree of similarity, leading to the conclusion that the goal of identifying a generic list of CSFs for project management has been achieved. Therefore, rather than continuing to describe lists of CSFs, researchers could increase the value of their contribution by taking a step forward and focusing on why, despite this apparent knowledge of how to ensure their success, ERP projects continue to fail.

    2007-01-01

    This study group was initiated to consider whether there were any 'show-stopper' issues with accelerators for heavy-ion warm-dense matter (WDM) and heavy-ion inertial fusion energy (HIF), and to prioritize them. Showstopper issues appear to be categorized as limits to beam current; that is, the beam is expected to be well-behaved below the current limit, and significantly degraded in current or emittance if the current limit is exceeded at some region of an accelerator. We identified 14 issues: 1-6 could be addressed in the near term, 7-10 may provide attractive solutions to performance and cost issues, 11-12 address multibeam effects that cannot be more than partially studied in near-term facilities, and 13-14 address new issues that are present in some novel driver concepts. Comparing the issues with the new experimental, simulation, and theoretical tools that we have developed, it is apparent that our new capabilities provide an opportunity to reexamine and significantly increase our understanding of the number one issue--halo growth and mitigation

  19. Critical thinking, nurse education and universities: some thoughts on current issues and implications for nursing practice.

    Science.gov (United States)

    Morrall, Peter; Goodman, Benny

    2013-09-01

    When in the latter part of the 20th century nurse 'training' in the UK left the old schools of nursing (based within the health delivery system) and entered universities, the promise was not just a change of focus from training to education but an embracement of 'higher' education. Specifically, nurses were to be exposed to the demands of thinking rather than just doing - and critical thinking at that. However, despite a history of critical perspectives informing nursing theory, that promise may be turning sour. The insidious saturation of the university system in bureaucracy and managerialism has, we argue, undermined critical thinking. A major funding restructuring of higher education in the UK, coinciding with public concern about the state of nursing practice, is undermining further the viability of critical thinking in nursing and potentially the acceptability of university education for nurses. Nevertheless, while critical thinking in universities has decayed, there is no obvious educational alternative that can provide this core attribute, one that is even more necessary to understand health and promote competent nursing practice in an increasingly complex and globalising world. We propose that nurse academics and their colleagues from many other academic and professional disciplines engage in collegiate 'moral action' to re-establish critical thinking in UK universities.

    Full Text Available This Special Issue documents not only the more recent progress made in detecting and attributing changes in temperature and precipitation extremes in the observational record, but also in projecting changes in such extremes at regional and local scales. It also deals with the impacts and other consequences and implications of both the historic and anticipated changes in extreme weather and climate events. Impact assessments using both dynamical downscaling and statistical modelling for two tropical cyclones are reported, as well as for storm surge and extreme wave changes. The Special Issue concludes with a consideration of some policy implications and practical applications arising from our relatively robust understanding of how the build up of greenhouse gases in the Earth’s atmosphere affects weather and climate extremes.

    2017-06-01

    Full Text Available Many resources are invested in measurement processes of projects indicators without, however, give a clear view of which projects deserves the right attention at the right time. This paper proposes the use of statistics, through the analysis of multiple variables and their interrelationships, to give better basis to a critical assessment methodology of current projects used in a multinational mining company. The contribution of the research is to report the methodology called Critical Radar which is based on a graphical tool with simple operationalization that can support the decision making in complex environments, and has great flexibility across the different market scenarios and possible changes in companies guidelines. The tool has great potential to help evaluate current projects due to their characteristics of flexible use in different business areas; high degree of freedom for improvement; use of known market tool in its development; ease of viewing the results through charts and notes and user freedom to use any existing indicators in the company if complied with some statistical data quality characteristics.

    The artificial pancreas combines a hormone infusion pump with a continuous glucose monitoring device, supported by a dosing algorithm currently installed on the pump. It allows for dynamic infusions of insulin (and possibly other hormones such as glucagon) tailored to patient needs. For patients with type 1 diabetes the artificial pancreas has been shown to prevent more effectively hypoglycaemic events and hyperglycaemia than insulin pump therapy and has the potential to simplify care. However, the potential ethical issues associated with the upcoming integration of the artificial pancreas into clinical practice have not yet been discussed. Our objective was to identify and articulate ethical issues associated with artificial pancreas use for patients, healthcare professionals, industry and policymakers. We performed a literature review to identify clinical, psychosocial and technical issues raised by the artificial pancreas and subsequently analysed them through a common bioethics framework. We identified five sensitive domains of ethical issues. Patient confidentiality and safety can be jeopardized by the artificial pancreas' vulnerability to security breaches or unauthorized data sharing. Public and private coverage of the artificial pancreas could be cost-effective and warranted. Patient selection criteria need to ensure equitable access and sensitivity to patient-reported outcomes. Patient coaching and support by healthcare professionals or industry representatives could help foster realistic expectations in patients. Finally, the artificial pancreas increases the visibility of diabetes and could generate issues related to personal identity and patient agency. The timely consideration of these issues will optimize the technological development and clinical uptake of the artificial pancreas. Copyright © 2018. Published by Elsevier Masson SAS.

    The learning models used in traditional education are not very effective for the continuing education of healthcare providers. Fieldwork learning is an active learning method that is feasible in the workplace and is also suitable for professionals who possess a style of experiential learning. Guardian Angel 2.0® is a fieldwork learning project designed to promote educational skills in nurses to improve the self-care and quality of life in women affected by osteoporosis. The purpose of this article is to present the Guardian Angel 2.0® project and its results. The Guardian Angel 2.0® effort lasted nine months and involved 212 nurses in the north, centre and south of Italy. A socio-demographic questionnaire, an evaluation scale of the learning process and a participants' satisfaction questionnaire were used to evaluate and monitor the fieldwork learning project. Out of the 212 nurses who participated in the project, 119 (70%) completed it. The mean age of these participants was 48 years (± 7.98), and 83.5% were female. About half of the participants (52.0%, 55.4% and 45.0%, respectively) were good (a) at respecting deadlines, (b) at using the methodological instruments and (c) the information tools properly. Almost all nurses considered the project to be very relevant (96.4%). In regards to the project's quality, the nurses perceived it as excellent (51.0%) and very good (48.5%). Finally, the project was considered very useful or useful by 100% of nurses. The general satisfaction of nurses was high. The fieldwork learning was relevant and useful for developing educational skills in nurses. It would therefore be appropriate to use fieldwork learning in clinical settings to improve the existing experience of healthcare providers and thereby reduce the difficulties of transforming the knowledge from a theoretical to a practical level and to promote the development of new behaviours when the existing ones become obsolete or inefficient.

    1995-01-01

    The Fifth International Conference on Nuclear Criticality Safety (ICNC'95) was held September 17-22, 1995, in Albuquerque, New Mexico, USA. Organization and support for the conference was provided by the Sandia National Laboratories (SNL), Los Alamos National Laboratory (LANL), the University of New Mexico, and the Organization for Economic Cooperation and Development (OECD). This conference traces its history back to 1981 when a group of select criticality safety specialists (mostly experimentalists) from France, Germany, Japan, the United Kingdom, and the United States participated in a small conference at LANL in the United States. The motivation for the conference had been provided by Dr. J. C. Manaranche of France who had asked D. Smith and G. E. Whitesides of the United States if it would be possible for the French experimentalists to be able to visit the experimental facilities at LANL. This first conference was followed by a similar conference held in Dijon, France, in 1993. Then in 1987 the conference was hosted by the Japanese and opened to much wider participation by criticality safety specialists involved in experiments, methods development and analysis, and operations. With the 1987 conference in Japan and the fourth conference (ICNC'91) held in the United Kingdom, the interest and international participation by the criticality safety community has grown rapidly. With this background, the occasion of ICNC'95 was one of much expectation

    Since 1997, the Critical Chain Project Management (CCPM) method has received considerable attention. Hundreds of successful CCPM cases have achieved highly reliable on-time delivery (OTD) with short project lead-time (PLT) in multi-project environments. However, two obstacles have remained, blocking the implementation of CCPM to project management (PM) society. The first has been addressed by PM practitioners, who have been less than confident that OTD and PLT can be significantly improved by...

  4. Critical issues in enhancing brightness in thin film phosphors for flat-panel display applications

    2002-01-01

    Thin film phosphors have potential applications in field emission flat-panel displays. However, they are limited by the lower cathodoluminescent brightness in comparison to phosphor powders. In this paper, we have investigated the critical parameters that need to be optimized to increase the brightness of phosphor thin films. Specifically, we studied the role of surface roughness and optical properties of the substrate on the brightness of the phosphor films. Thin Y 2 O 3 :Eu phosphor films were deposited on various substrates (lanthanum aluminate, quartz, sapphire, and silicon) with thicknesses varying from 50 to 500 nm. A model that accounts for diffuse and specular or scattering effects has been developed to understand the effects of the microstructure on the emission characteristics of the cathodoluminescent films. The results from the model show that both the optical properties of the substrate and the surface roughness of the films play a critical role in controlling the brightness of laser deposited phosphor films

    The Project on construction for a new research reactor in Vietnam is under preparation. At the same time, it is necessary to prepare a firm and comprehensive national nuclear infrastructure which is aimed to implement smoothly and ensure safety and security for the project. How is the status of the nuclear infrastructure for research reactor project in Vietnam, how can it be assessed, what is the assessment used for and what are we going to do with that? So, all of these things are the goals set out to address in this Task. However, due to time constraints and conformity with requirement of project progress, this Task assessed only 8 critical issues in infrastructure in phase 1&2, including National position; Management; Legislative framework; Regulatory framework; Human resource development; Radioactive waste; Site survey, site selection and evaluation; and Environmental protection. Conditions and criteria in the documents on milestones and assessment of the national nuclear infrastructure to support a new research reactor project of the International Atomic Energy Agency (IAEA) were used as bases for assessing the Vietnam's infrastructure status. The results of the Task are assessment and identification for gaps which need to be addressed and proposing for a plan on completing the national nuclear infrastructure for the research reactor project on 8 issues in stages 1&2.

    Full Text Available This paper emphasizes the importance of groundwater resources of Rome with regard to its protection, and the associated issues. There are different tipologies of interference between human presence and groundwater in the city, ranging from the presence of water circulating inside the thick layers of anthropogenic deposits, the frequent contamination of groundwater, the presence of mining activities, the presence of archaeological heritage in underground or in low areas affected by flooding also induced by water table rising. Despite the various issues that are found, the knowledge of groundwater resources of Rome can be an important starting point to enhance its protection s and take advantage of the related countless benefits also aim to increase urban resilience.

  9. Critical corrosion issues and mitigation strategies impacting the operability of LWR's

    International Nuclear Information System (INIS)

    Jones, R.L.

    1996-01-01

    Recent corrosion experience in US light water reactor nuclear power plants is reviewed with emphasis on mitigation strategies to control the cost of corrosion to LWR operators. Many components have suffered corrosion problems resulting in industry costs of billions of dollars. The most costly issues have been stress corrosion cracking of stainless steel coolant piping in boiling water reactors and corrosion damage to steam generator tubes in pressurized water reactors. Through industry wide R and D programs these problems are now understood and mitigation strategies have been developed to address the issues in a cost effective manner. Other significant corrosion problems for both reactor types are briefly reviewed. Tremendous progress has been made in controlling corrosion, however, minimizing its impact on plant operations will present a continuing challenge throughout the remaining service lives of these power plants

    Full Text Available Abstract Background In keeping with the fundamental practice of transparency in the discussion and resolution of ethics conflicts raised by research, a summary of ethics issues raised during Portuguese biomonitoring in health surveillance and research is presented and, where applicable, their resolution is described. Methods Projects underway aim to promote the surveillance of public health related to the presence of solid waste incinerators or to study associations between human exposure to environmental factors and adverse health effects. The methodological approach involves biomonitoring of heavy metals, dioxins and/or other persistent organic pollutants in tissues including blood, human milk and both scalp and pubic hair in groups such as the general population, children, pregnant women or women attempting pregnancy. As such, the projects entail the recruitment of individuals representing different demographic and health conditions, the collection of body tissues and personal data, and the processing of the data and results. Results The issue of autonomy is raised during the recruitment of participants and during the collection of samples and data. This right is protected by the requirement for prior written, informed consent from the participant or, in the case of children, from their guardian. Recruitment has been successful, among eligible participants, in spite of incentives rarely being offered. The exception has been in obtaining guardians' consent for children's participation, particularly for blood sampling. In an attempt to mitigate the harm-benefit ratio, current research efforts include alternative less invasive biomarkers. Surveys are currently being conducted under contract as independent biomonitoring actions and as such, must be explicitly disclosed as a potential conflict of interests. Communication of results to participants is in general only practised when a health issue is present and corrective action possible

  13. Critical issues with clinical research in children: The example of premature infants

    Welty, Stephen E.

    2005-01-01

    Research in pediatrics has led to marked improvements in survival in pediatric patients. In no other age group have these improvements been more dramatic than in neonatology, where antenatal steroid administration to mothers and postnatal utilization of surfactant have led to marked improvements in survival so that infants born at 24 weeks gestation now have a greater than 50% chance of survival. Unfortunately, more than 50% of these patients develop significant complications of prematurity with potential long-term impact on the health of these infants. Therefore, additional research must be done in these patients to prevent these complications or reduce the impact of these complications. There are many practical and some ethical issues that could impede research in the area. Interventional studies have succeeded because literally decades of research defined unequivocally the pathophysiology of diseases such as surfactant deficiency in RDS. Unfortunately, the pathophysiology leading to the complications of prematurity has been extrapolated from old concepts without verification as the population has become smaller and more premature than the previous era. Thus, an extremely important practical issue in pediatric research is whether to design interventions to address the extrapolated pathophysiology risking misinterpretations of the results of such studies. Or should our efforts be focused on defining endpoints associated with the development of diseases and complications which may define pathophysiology more completely but delay the design of interventions to improve the outcomes of patients. Another crucial practical issue in pediatric research is how to power studies so that interventions can be studied adequately. In the US, large neonatal networks have been formed so that large databases can be created and large multi-center trials can be performed. The practical issues associated with these network studies is the center to center variability in patient care

    There is still uncertainty about what constitutes the best therapeutic practice in ulcerative colitis (UC). The purpose of the "UC Horizons Project" was to raise a series of questions regarding the management of UC to provide responses based on the best scientific evidence available. The 11 members of the scientific committee prepared draft answers to the 10 questions from available evidence after a literature search. A total of 48 Spanish gastroenterology specialists nationwide participated in the project. The national meeting discussed the 10 issues in working groups and reached consensus regarding the recommendations by anonymous, interactive vote following the Delphi methodology. Final answers were developed, based on evidence and clinical experience of the participants. All the recommendations achieved a high level of agreement in the plenary vote, although the quality of the evidence was markedly heterogeneous. The lowest percentage of agreement corresponded to the questions with the weakest level of evidence, highlighting the necessity of conducting further studies in these areas. The recommendations focused on (1) aminosalicylates therapy (regarding dose and appropriateness of coadministration with thiopurines), (2) corticosteroid therapy (regarding dose and route of administration), (3) thiopurine treatment (regarding indications and possibility of withdrawal), (4) anti-tumor necrosis factor therapy (regarding appropriateness of combination with thiopurines, intensification, or discontinuation of treatment), and (5) colorectal cancer (regarding risk and time trends). The UC Horizons Project raised a series of eminently practical questions about the management of UC and provided responses based on the best scientific evidence available.

    This report analyses latent factors of a human behavior directly contributing to the criticality accident. It is pouring some 16 kg-U with an enrichment of 18.8% into the precipitation tank. It is the fact that the direct cause of this accident is the workers' unsafe act. However, the authors find lots of latent factors relating to the production-biased company's policy, the poor climate for safety in the work place, the inadequate safety management and the unsuitable equipment. This accident was caused by many organizational factors. This paper also discusses lessons learned from this accident. (author)

    Full Text Available The paper first presents basic information about the Scrum method. Then it summarizes the state of art in the domain of Scrum implementation, especially as far as the critical factors of its success are concerned. On the basis of literature survey a new model classifying Scrum implementation critical factors is proposed. The model divides Scrum implementation critical factors into five categories: Project Team factors, Psychological and cultural factors, Process and Method, Environment and Technology. The model is then developed and verified using the case study method. The research was carried out in a French IT company by means of a participating observation. The company was implementing Scrum, which ended up as a success. A journal of the Scrum implementation was conducted, presenting the experiences of the Scrum Team, their opinions and changes in the Scrum method which were introduced. On its basis critical factors, crucial for the success of Scrum implementation, classified according to the above mentioned model, were identified, completing those which had been found in the literaturę.

  17. Development of a criticality alarm system neutron detector: Final project report

    1989-05-01

    The primary objective of this project was to develop a prototype neutron detector for use in criticality alarm systems (CASs) at US Department of Energy (DOE) and contractor facilities wherever significant amounts of fissile material are processed or stored. Constraints placed on the design of the detector were that the overall size of the detector was to be as small as practical, the input voltage requirements were to be no more than 24 V, and that the gamma sensitivity would be as low as possible. Also, the detector should give dosimetric neutron response, and should have sufficient temporal capabilities to measure the entire range from fast (>1 ms) to slow (seconds to minutes) excursions, and sufficient dynamic range to measure from background to over 100 times background levels to insure proper activation of the Immediate Evacuation Alarm (IEA). Finally, the detector should insure rapid (<1 s) activation of the IEA in the event of a criticality excursion. 24 figs., 11 tabs

    This article shows that variations in how two UK governments justified contracting-out (issue framing), combined with shifting sector-derived incentives for union activism (sector character), can help explain the extent of contracting-out. Janitorial service, an activity of the UK government......, and its reform faced unions that stood to lose a great deal from movement of janitorial jobs to private firms. In contrast, the New Labour government framed contracting-out broadly, as a means to efficient social justice, and faced unions with low stakes in government janitors. As a consequence, UK...

    In the ITER-FEAT, the most severe loading conditions for the VV are the toroidal field coil fast discharge (TFCFD) and its load combination with electromagnetic loads due to a plasma vertical instability, which cause high compressive stresses in the VV inboard wall and increase the risk of buckling. Detailed analyses need to be performed to assess the stress level at the geometrical discontinuities and where concentrated loads are applied. The nuclear heating and the presence of gaps between the blanket modules cause concentrated nuclear heat loads.

This issue is the collection of 41 papers presented at the entitled meeting. All the 41 of the presented papers are indexed individually. (J.P.N.)

  2. Are optimal CO2 emissions really optimal? Four critical issues for economists in the greenhouse

    International Nuclear Information System (INIS)

    Azar, C.

    1998-01-01

    Although the greenhouse effect is by many considered as one of the most serious environmental problems, several economic studies of the greenhouse effect, most notably Nordhaus's DICE model, suggest that it is optimal to allow the emissions of greenhouse gases (GHG) to increase by a factor of three over the next century. Other studies have found that substantial reductions can be justified on economic grounds. This paper explores into the reasons for these differences and identifies four (partly overlapping) crucial issues that have to be dealt with when analysing the economics of the greenhouse effect low-probability but catastrophic events; cost evaluation methods; the choice of discount rate; the choice of decision criterion. The paper shows that (1) these aspects are crucial for the policy conclusions drawn from models of the economics of climate change, and that (2) ethical choices have to be made for each of these issues. This fact needs wider recognition since economics is very often perceived as a value neutral tool that can be used to provide policy makers with 'optimal' policies. 62 refs

  3. Online Higher Education Instruction to Foster Critical Thinking When Assessing Environmental Issues - the Brownfield Action Model

    2013-04-01

    According to the Environmental Protection Agency, there are presently over half a million brownfields in the United States, but this number only includes sites for which an Environmental Site Assessment has been conducted. The actual number of brownfields is certainly into the millions and constitutes one of the major environmental issues confronting all communities today. Taught in part online for more than a decade in environmental science courses at over a dozen colleges, universities, and high schools in the United States, Brownfield Action (BA) is an interactive, web-based simulation that combines scientific expertise, constructivist education philosophy, and multimedia to advance the teaching of environmental science (Bower et al., 2011). In the online simulation and classroom, students form geotechnical consulting companies, conduct environmental site assessment investigations, and work collaboratively to solve a problem in environmental forensics. The BA model contains interdisciplinary scientific and social information that are integrated within a digital learning environment that encourages students to construct their knowledge as they learn by doing. As such, the approach improves the depth and coherence of students understanding of the course material. Like real-world environmental consultants, students are required to develop and apply expertise from a wide range of fields, including environmental science and engineering as well as journalism, medicine, public health, law, civics, economics, and business management. The overall objective is for students to gain an unprecedented appreciation of the complexity, ambiguity, and risk involved in any environmental issue or crisis.

  4. The glial response to intracerebrally delivered therapies for neurodegenerative disorders: Is this a critical issue?

    Directory of Open Access Journals (Sweden)

    Francesca eCicchetti

    2014-07-01

    Full Text Available The role of glial cells in the pathogenesis of many neurodegenerative conditions of the central nervous system (CNS is now well established (as is discussed in other reviews in this special issue of Frontiers in Neuropharmacology. What is less clear is whether there are changes in these same cells in terms of their behaviour and function in response to invasive experimental therapeutic interventions for these diseases. This has, and will continue to, become more of an issue as we enter a new era of novel treatments which require the agent to be directly placed/infused into the CNS such as deep brain stimulation, cell transplants, gene therapies and growth factor infusions. To date, all of these treatments have produced variable outcomes and the reasons for this have been widely debated but the host astrocytic and/or microglial response induced by such invasively delivered agents has not been discussed in any detail. In this review, we have attempted to summarise the limited published data on this, in particular we discuss the small number of human post-mortem studies reported in this field. By so doing, we hope to provide a better description and understanding of the extent and nature of both the astrocytic and microglial response, which in turn could lead to modifications in the way these therapeutic interventions are delivered.

    Breiing, Marcus; Cole, Mara; D'Avanzo, John; Geiger, Gebhard; Goldner, Sascha; Kuhlmann, Andreas; Lorenz, Claudia; Papproth, Alf; Petzel, Erhard; Schwetje, Oliver

    This paper outlines the scientific goals, ongoing work and first results of the SiVe research project on critical infrastructure security. The methodology is generic while pilot studies are chosen from airport security. The outline proceeds in three major steps, (1) building a threat scenario, (2) development of simulation models as scenario refinements, and (3) assessment of alternatives. Advanced techniques of systems analysis and simulation are employed to model relevant airport structures and processes as well as offences. Computer experiments are carried out to compare and optimise alternative solutions. The optimality analyses draw on approaches to quantitative risk assessment recently developed in the operational sciences. To exploit the advantages of the various techniques, an integrated simulation workbench is build up in the project.

This study used quasi-experimental posttest only control group design. The sample consisted of three classes, which were XI MIA-4class (n = 32 that learned using 5E LC model, XI MIA-5 class (n = 33 that learned using 5E LC+SSI, and XI MIA-6 class (n = 32 that learned using conventional method. The samples were choosen by convenience sampling technique. The test instrument consisted of 15 multiple choice items which were valid and reliable (r = 0.806. The data were analyzed using one way ANOVA test and LSD posthoc test. The results of this study indicated that the students who learned using 5E LC+SSI model showed greater levels of critical thinking skills (  = 74,95 than both the student who learned using 5E LC model (  = 74,17 and  the student who learned using conventional method (  = 68,96. Based on statistics analysis, there was significant differences on students’ critical thinkings between students taught using conventional method and students taught either using 5E LC+SSI model and 5E LC model. However,  there was no significant differences on students’ critical thinking skills between students taught using 5E LC+SSI model and the students taught using 5E LC model.

    The programmatic, facility and criticality safety support staffs at the LLNL Plutonium Facility worked together to successfully develop and implement a project to process legacy (DNFSB Recommendation 94-1 and non-Environmental, Safety, and Health (ES and H) labeled) materials in storage. Over many years, material had accumulated in storage that lacked information to adequately characterize the material for current criticality safety controls used in the facility. Generally, the fissionable material mass information was well known, but other information such as form, impurities, internal packaging, and presence of internal moderating or reflecting materials were not well documented. In many cases, the material was excess to programmatic need, but such a determination was difficult with the little information given on MC and A labels and in the MC and A database. The material was not packaged as efficiently as possible, so it also occupied much more valuable storage space than was necessary. Although safe as stored, the inadequately characterized material posed a risk for criticality safety noncompliances if moved within the facility under current criticality safety controls. A Legacy Item Implementation Plan was developed and implemented to deal with this problem. Reasonable bounding conditions were determined for the material involved, and criticality safety evaluations were completed. Two appropriately designated glove boxes were identified and criticality safety controls were developed to safely inspect the material. Inspecting the material involved identifying containers of legacy material, followed by opening, evaluating, processing if necessary, characterizing and repackaging the material. Material from multiple containers was consolidated more efficiently thus decreasing the total number of stored items to about one half of the highest count. Current packaging requirements were implemented. Detailed characterization of the material was captured in databases

    Full Text Available Oil and gas development projects are well known to have damaging environmental effects, and that is especially true in the Niger Delta region. Since the enactment of the Environmental Impact Assessment Act in Nigeria in 1992, there has been a general perception that EIAs are seldom carried out in the region. This article presents a critical analysis of legislation and practice concerning the environmental impact assessment (EIA process for oil and gas projects in Nigeria, the world’s twelfth largest producer of crude oil. It discusses a range of reasons why the impacts of oil and gas projects are not being managed well, despite the legal requirements for EIAs. A review of Nigeria’s environmental governance is presented along with a comprehensive discussion of the EIA process and its significant deficiencies. We argue that the EIA system for oil and gas projects in Nigeria reflects tokenism, resulting in the concentration of benefits of developments in big corporations and government officials. The EIA process in Nigeria faces many challenges that must be addressed in order to improve its effectiveness and alleviate the environmental burdens on this rich oil-producing region.

    Teodoro Negri

    1993-12-01

    Full Text Available Pasolini departs from the diagnosis of a problem: the critical quest stage in contemporary literature, centered on the 1950s; he points out the author´s inability to create the design for a national language. He goes on to analyze the deep mutation in Italian Society, which determineted a new socio-linguistic outlook; to wit, a language clearly marked by strong technicality and instrumentation. Drawing examples from newspapers, TV features, official political speeches and commercials, Pasolini demonstrates that factual communication takes precedence over formal expression. This is ascribed to one principle which sets both rules and approvals for all forms of national language. This fact, according to Pasolini, is the result of an industrial and technological transformation process, which would  permite advent of a new linguistic bourgeoisie. The linguistic unification caused by such approving  principle would, therefore, imply the social manifestation of the bourgeoisie.

    Critical heat flux (CHF) is manifested by sharp reduction in heat transfer coefficient and a drastic rise in fuel rod surface temperature, which may lead to failure of the fuel cladding and is of immense importance in reactor design and operation. In this paper, the existing literature on CHF is studied and analyzed. Different modeling techniques such as geometry modeling and fluid modeling are highlighted. CHF enhancement techniques such as swirl flow, porous coating, nano-fluids or mechanical vibrations are analyzed and their suitability for different applications is discussed. The advances in prediction methods for tubes and rod bundles are also presented. CHF correlations and their applications have been compiled to estimate the CHF for fluids other than water or other geometries. Finally, future research needs are identified and presented. (authors)

  14. Women's occupational health: a critical review and discussion of current issues.

    Science.gov (United States)

    Messing, K

    1997-01-01

    Action to improve women's occupational health has been slowed by a notion that women's jobs are safe and that any health problems identified among women workers can be attributed to unfitness for the job or unnecessary complaining. With increasing numbers of women in the labor force, the effects of work on women's health have recently started to interest health care providers, health and safety representatives and researchers. We begin our summary of their discoveries with a discussion of women's place in the workplace and its implications for occupational health, followed by a brief review of some gender-insensitive data-gathering techniques. We have then chosen to concentrate on the following four areas: methods and data collection; directing attention to women's occupational health problems; musculoskeletal disease; mental and emotional stress. We conclude by pointing out some neglected occupational groups and health issues.

    2002-07-01

    An issue scoping process to focus the soil impact assessment undertaken in conjunction with Suncor Energy's Voyageur Project near Fort McMurray, Alberta, is described. Potential impacts to soils considered include disturbances from mining and in-situ developments, re-constructing soils to meet equivalent capability and predicting how soils will respond to acid deposition. The assessment also provides an opportunity to evaluate unique soil mitigation strategies at both the local and regional levels. New regulatory and soil reclamation challenges include developing soil salvage criteria for restoring the biodiversity which existed prior to the disturbance necessitated by the mining and in-situ operations and creating a suitable habitat for the caribou in the Firebag lease.

    Development of cross border gas transmission projects raise complex and interdependent issues whose successful resolution require not only technical and management strengths but also a close cooperation between the key players involved in the game. In this paper we shall attempt to explain some of the major issues encountered during the appraisal and construction of long distance gas pipeline schemes. The information used derive essentially from the experience gained during the development of the Trans-mediterranean and the Maghreb/Europe pipelines. Running through the various issues we shall also identify and then discuss a number of factors which contributed to the successful implementation of these two projects. (au)

  19. Safety culture and subcontractor network governance in a complex safety critical project

    International Nuclear Information System (INIS)

    Oedewald, Pia; Gotcheva, Nadezhda

    2015-01-01

    In safety critical industries many activities are currently carried out by subcontractor networks. Nevertheless, there are few studies where the core dimensions of resilience would have been studied in safety critical network activities. This paper claims that engineering resilience into a system is largely about steering the development of culture of the system towards better ability to anticipate, monitor, respond and learn. Thus, safety culture literature has relevance in resilience engineering field. This paper analyzes practical and theoretical challenges in applying the concept of safety culture in a complex, dynamic network of subcontractors involved in the construction of a new nuclear power plant in Finland, Olkiluoto 3. The concept of safety culture is in focus since it is widely used in nuclear industry and bridges the scientific and practical interests. This paper approaches subcontractor networks as complex systems. However, the management model of the Olkiluoto 3 project is to a large degree a traditional top-down hierarchy, which creates a mismatch between the management approach and the characteristics of the system to be managed. New insights were drawn from network governance studies. - Highlights: • We studied a relevant topical subject safety culture in nuclear new build project. • We integrated safety science challenges and network governance studies. • We produced practicable insights in managing safety of subcontractor networks

  20. Critical Issues for Producing UHTC-Brazed Joints: Wetting and Reactivity

    Science.gov (United States)

    Passerone, A.; Muolo, M. L.; Valenza, F.

    2016-08-01

    A brief survey is presented of the most important interaction phenomena occurring at the solid-liquid interfaces in metal-ceramic systems at high temperatures, with special attention to the most recent developments concerning wetting and joining transition metals diborides. These phenomena are described and discussed from both the experimental and theoretical points of view in relation to joining ceramic and metal-ceramic systems by means of processes in the presence of a liquid phase (brazing, TLPB etc.). It is shown that wetting and the formation of interfacial dissolution regions are the results of the competition between different phenomena: dissolution of the ceramic in the liquid phase, reaction and formation of new phases at the solid-liquid interface, and drop spreading along the substrate surface. We emphasize the role of phase diagrams to support both the design of the experiments and the choice of active alloying elements, and to interpret the evolution of the system in relation to temperature and composition. In this respect, the sessile-drop technique has been shown to be helpful in assessing critical points of newly calculated phase diagrams. These studies are essential for the design of joining processes, for the creation of composite materials, and are of a particular relevance when applied to UHTC materials.

  1. Immune Monitoring in Cancer Vaccine Clinical Trials: Critical Issues of Functional Flow Cytometry-Based Assays

    Directory of Open Access Journals (Sweden)

    Iole Macchia

    2013-01-01

    Full Text Available The development of immune monitoring assays is essential to determine the immune responses against tumor-specific antigens (TSAs and tumor-associated antigens (TAAs and their possible correlation with clinical outcome in cancer patients receiving immunotherapies. Despite the wide range of techniques used, to date these assays have not shown consistent results among clinical trials and failed to define surrogate markers of clinical efficacy to antitumor vaccines. Multiparameter flow cytometry- (FCM- based assays combining different phenotypic and functional markers have been developed in the past decade for informative and longitudinal analysis of polyfunctional T-cells. These technologies were designed to address the complexity and functional heterogeneity of cancer biology and cellular immunity and to define biomarkers predicting clinical response to anticancer treatment. So far, there is still a lack of standardization of some of these immunological tests. The aim of this review is to overview the latest technologies for immune monitoring and to highlight critical steps involved in some of the FCM-based cellular immune assays. In particular, our laboratory is focused on melanoma vaccine research and thus our main goal was the validation of a functional multiparameter test (FMT combining different functional and lineage markers to be applied in clinical trials involving patients with melanoma.

  2. Critical issues in the historical and contemporary development of forensic anthropology in Australia: An international comparison.

    Science.gov (United States)

    Mallett, Xanthé; Evison, Martin P

    2017-06-01

    The aim of this brief critical qualitative analysis is to examine the development of forensic anthropology in Australia, at a time of significant change in the discipline. It will briefly summarise its historical establishment, making comparative reference to other regions-particularly the United Kingdom and United States, and the influence of the Bali Bombings of 2002, Indian Ocean earthquake and tsunami of 2004 and Black Saturday Bushfires of 2009. The analysis goes on to consider key factors in research in forensic anthropology in the United States, and the development of standards and regulation in the US and UK. The significance of research in post-mortem diagenesis in Brazil-a country sharing aspects of climate, soil types and demography with Australia-is also considered, as well as the significance of patterns of casework encountered in Australia compared with those of other jurisdictions. While forensic anthropology as a discipline has grown remarkably in recent years, this analysis suggests that research and training tailored to the specific pattern of casework encountered in Australia is now essential to support the development of national standards in science, education, and professional regulation. The significance of the establishment of the first taphonomy research facility outside of the US-the Australian Facility for Taphonomic Experimental Research-is briefly considered with reference to what this facility may offer to the development of forensic anthropology in Australia.

    Full Text Available Along with the processes of digitization, medialization and the globalization of communications and lifeworlds, new topics, subject matters, conceptualizations and methods have been deve­loped in educational research and practice. On the one hand, from a diachronic perspective we can notice how new aspects of education (Bildung, upbringing (Erziehung, learning and communication have been addressed. On the other hand, from a synchronic perspective we can see a simultaneity of the non-simultaneous in terms of understandings, approaches, methodologies and forms of mediation and collaboration. Although more and more open initiatives and open educational resources (OER, as well as international collaborations and transnational intellectual networks, are being brought forward, epistemological aspects about using different key concepts are widely underestimated. The paper starts with: (1 an outline of selected understandings of education and literacy, followed by (2 a discussion of critical epistemological aspects by way of contrasting and correlating conceptual dimensions. Lastly, the contribution aims at (3 a sketch of polylogical design principles for educational knowledge organization.

  4. Milrinone Dosing Issues in Critically Ill Children With Kidney Injury: A Review.

    Science.gov (United States)

    Gist, Katja M; Goldstein, Stuart L; Joy, Melanie S; Vinks, Alexander A

    2016-02-01

    Milrinone is an inotropic drug used in a variety of clinical settings in adults and children. The efficacy of milrinone in pediatric low-cardiac output syndrome after cardiac surgery is reported. Its primary route of removal from the body is through the kidney as unchanged drug in the urine. Milrinone is not known to be efficiently removed by extracorporeal dialytic therapies and thus has the potential to cause serious adverse effects and potentially worsens renal function in patients experiencing acute kidney injury (AKI). AKI is an important public health issue that is associated with increased morbidity, mortality, and cost. It is a known risk factor for the development of chronic kidney disease. There are no specific therapies to mitigate AKI once it has developed, and interventions are focused on supportive care and dose adjustment of medications. Estimating glomerular filtration rate based on height and serum creatinine is the most commonly used clinical method for assessing kidney function and modification of medication doses. The purpose of this review is to discuss our current understanding of milrinone pharmacokinetics and pharmacodynamics in children with AKI and to describe the potential use of urinary biomarkers to guide therapeutic decision making for milrinone dosing.

  5. The critical issue of nuclear power plant safety in developing countries

    International Nuclear Information System (INIS)

    Rosen, M.

    1977-01-01

    A little more than a decade from now, large commercial nuclear power facilities will be in operation in almost 40 countries, of which approximately one-half are presently considered industrially less developed. Ambitious nuclear programmes coupled with minimal and frequently under-staffed regulatory and utility organizations are only one aspect of the difficulties related to the safety of nuclear plants that face these developing countries. Inherent problems of meeting current safety standards and requirements for the significantly non-standard nuclear power plant exports can be compounded by financial considerations that may lead to purchases of reactors of various types, from more than one supplier country and with different safety standards and requirements. An examination of these issues points to the necessity and opportunity for effective action which could include provision for adequate funding for safety considerations in the purchase contract, and for sufficient regulatory assistance and training from the developed countries. The article will introduce the topic, discuss specific examples, and offer some suggestions. (author)

  6. Getting ready for malaria elimination: a check list of critical issues to consider

    Directory of Open Access Journals (Sweden)

    Matiana González-Silva

    2014-08-01

    Full Text Available In recent years, a renewed interest in malaria elimination and eradication has emerged and seems to be rooting in the minds of the scientific community, public health specialists, funding bodies, policy makers and politicians. Malaria eradication will certainly benefit from improved and innovative tools; notwithstanding novel knowledge in fields ranging from basic science to mathematical modelling and health systems research. However, the elimination of malaria also encompasses a broad range of essential aspects that countries and other actors need to consider when thinking of embarking on such an adventure, including the implementation of innovative strategies, the ability to incorporate the most up-to-date evidence into policy, the integration of malaria into the broader health agenda, the strengthening of surveillance and health systems, capacity building, funding, advocacy and, very importantly, research. While in some cases this enthusiasm is clearly justified, some countries are still a long way from realistically advancing towards elimination. This paper attempts to provide guidance on all the necessary issues that should be considered when initiating a malaria elimination program.

  7. Burnout in Orthopaedic Surgeons: A Challenge for Leaders, Learners, and Colleagues: AOA Critical Issues.

    Science.gov (United States)

    Ames, S Elizabeth; Cowan, James B; Kenter, Keith; Emery, Sanford; Halsey, David

    2017-07-19

    Burnout, depression, suicidal ideation, and dissatisfaction with work-life balance have been reported in all medical specialties and at all stages of medical education and practice experience. Burnout consists of progressive emotional, attitudinal, and physical exhaustion. Physicians with burnout may treat patients as objects and feel emotionally depleted. Burnout is characterized by a loss of enthusiasm for work (emotional exhaustion), feelings of cynicism (depersonalization), and a low sense of personal accomplishment. The most complete study of emotional burnout among different medical specialties demonstrated that orthopaedic surgery is one of the specialties with the highest burnout rate. Qualitative descriptive studies are available. There was a 45.8% burnout rate among physicians in the U.S. in 2012, and a 2014 update suggested even higher rates. Burnout has a correlation with medical education. Burnout rates are similar to those in the general population when medical students enter school, and increase steadily through medical education prior to residency. Burnout rates in residents are high, reported to be between 41% and 74% across multiple specialties. This impacts our young physician workforce in orthopaedics. The purpose of this review is to provide the available information that characterizes burnout and addresses the issues inherent to preventing burnout, and to build awareness in orthopaedic surgeons. Wellness "goes beyond merely the absence of distress and includes being challenged, thriving, and achieving success in various aspects of personal and professional life." The challenge for the orthopaedic community is to develop interventions and strategies that are personalized to the individuals in this specialty.

    Several continuous splits for wafer alignment target topography conditions to improve epitaxy film alignment were applied. The alignment evaluation among former layer pad oxide thickness (250 angstrom - 500 angstrom), drive oxide thickness (6000 angstrom - 10000 angstrom), nitride film thickness (600 angstrom - 1500 angstrom), initial oxide etch (fully wet etch, fully dry etch and dry plus wet etch) will be split to this experiment. Also various epitaxy deposition recipe such as: epitaxy source (SiHCl2 or SiCHCl3) and growth rate (1.3 micrometer/min approximately 2.0 micrometer/min) will be used to optimize the process window for alignment issue. All the reflectance signal and cross section photography of alignment target during NIKON stepper alignment process will be examined. Experimental results show epitaxy recipe plays an important role to wafer alignment. Low growth rate with good performance conformity epitaxy lead to alignment target avoid washout, pattern shift and distortion. All the results (signal monitor and film character) combined with NIKON's stepper standard laser scanning alignment system will be discussed in this paper.

    2017-01-01

    As the fraction of electricity generated from intermittent renewable sources (such as solar and wind) grows, developing reliable energy storage technologies to store electrical energy in large scale is of increasing importance. Redox flow batteries are now enjoying a renaissance and regarded as a leading technology in providing a well-balanced solution for current daunting challenges. In this article, state-of-the-art studies of the complex multicomponent transport phenomena in aqueous redox flow batteries, with a special emphasis on all-vanadium redox flow batteries, are reviewed and summarized. Rather than elaborating on the details of previous experimental and numerical investigations, this article highlights: i) the key transport issues in each battery's component that need to be tackled so that the rate capability and cycling stability of flow batteries can be significantly improved, ii) the basic mechanisms that control the active species/ion/electron transport behaviors in each battery's component, and iii) the key experimental and numerical findings regarding the correlations between the multicomponent transport processes and battery performance.

    Many communities in the United States are already vulnerable to extreme events; many of these vulnerabilities are likely to increase with climate change. In order to promote the development of effective community responses to climate change, we tested a participatory process for developing usable climate science, in which our project team worked with decision-makers to identify extreme event parameters and critical thresholds associated with policy development and adaptation actions. Our hypothesis is that conveying climate science and data through user-defined parameters and thresholds will help develop capacity to streamline the use of climate projections in developing strategies and actions, and motivate participation by a variety of preparedness planners. Our team collaborated with urban decision-makers, in departments that included resilience, planning, public works, public health, emergency management, and others, in four cities in the semi-arid south-central plains and intermountain areas of Colorado, New Mexico, Oklahoma, and Texas. Through an iterative process, we homed in on both simple and hybrid indicators for which we could develop credible city-specific projections, to stimulate discussion about adaptation actions; throughout the process, we communicated information about confidence and uncertainty, in order to develop a blend of historic and projected climate data, as appropriate, depending on levels of uncertainty. Our collaborations have resulted in (a) the identification of more than 50 unique indicators and thresholds across the four communities, (b) the development of adaptation action strategies in each community, and (c) the implementation of actions, ranging from a climate leadership training program for city staff members, to a rainwater capture project to improve responses to expected increases in both stormwater runoff and water capture for drought episodes.

  11. The PSI Artist Project: Aerosol Retention and Accident Management Issues Following a Steam Generator Tube Rupture

    Guntay, Salih; Dehbi, Abdel; Suckow, Detlef; Birchley, Jon

    2002-01-01

    Steam generator tube rupture (SGTR) incidents, such as those, which occurred in various operating pressurized, water reactors in the past, are serious operational concerns and remain among the most risk-dominant events. Although considerable efforts have been spent to understand tube degradation processes, develop improved modes of operation, and take preventative and corrective measures, SGTR incidents cannot be completely ruled out. Under certain conditions, high releases of radionuclides to the environment are possible during design basis accidents (DBA) and severe accidents. The severe accident codes' models for aerosol retention in the secondary side of a steam generator (SG) have not been assessed against any experimental data, which means that the uncertainties in the source term following an un-isolated SGTR concurrent with a severe accident are not currently quantified. The accident management (AM) procedures aim at avoiding or minimizing the release of fission products from the SG. The enhanced retention of activity within the SG defines the effectiveness of the accident management actions for the specific hardware characteristics and accident conditions of concern. A sound database on aerosol retention due to natural processes in the SG is not available, nor is an assessment of the effect of management actions on these processes. Hence, the effectiveness of the AM in SGTR events is not presently known. To help reduce uncertainties relating to SGTR issues, an experimental project, ARTIST (Aerosol Trapping In a Steam generator), has been initiated at the Paul Scherrer Institut to address aerosol and droplet retention in the various parts of the SG. The test section is comprised of a scaled-down tube bundle, a full-size separator and a full-size dryer unit. The project will study phenomena at the separate effect and integral levels and address AM issues in seven distinct phases: Aerosol retention in 1) the broken tube under dry secondary side conditions, 2

    This NASA Technical Memorandum is a compilation of presentations and discussions in the form of minutes from a workshop entitled 'Plant Production Systems for Microgravity: Critical Issues in Water, Air, and Solute Transport Through Unsaturated Porous Media' held at NASA's Johnson Space Center, July 24-25, 2000. This workshop arose from the growing belief within NASA's Advanced Life Support Program that further advances and improvements in plant production systems for microgravity would benefit from additional knowledge of fundamental processes occurring in the root zone. The objective of the workshop was to bring together individuals who had expertise in various areas of fluid physics, soil physics, plant physiology, hardware development, and flight tests to identify, discuss, and prioritize critical issues of water and air flow through porous media in microgravity. Participants of the workshop included representatives from private companies involved in flight hardware development and scientists from universities and NASA Centers with expertise in plant flight tests, plant physiology, fluid physics, and soil physics.

    Typically, a lot of interesting and important details add up to give a coherent and convincing picture of a safe repository. A good portion of these details must be studied and the scientific basis of the system must be clearly understood by the reviewing authority in order to be able to pass a judgement on the safety case. HSK has already received a large part of the documentation relating to the project, including the three high level documents that summarize the synthesis of the geological information, the demonstration of repository design and construction feasibility and the safety case. After a first look at the contents of the documentation we would like to complement Nagra on the maturity and clarity of the presentation in these reports. At this early stage, we shall not present any review judgements. The reviewer usually is dependent upon having not only the high level documents but also all the detailed reference reports in front of him in order to do his job, and HSK is still receiving very relevant documents. Thus we are still at the very beginning of our review. Here, we offer some comments of general nature about the review process and mention a few points that seem to be uppermost in our mind at this stage. (author)

  14. Critical issues in the choice of appropriate communication technology by Third World countries.

    Science.gov (United States)

    Sonaike, S A

    1987-01-01

    Recent experience suggests that the most appropriate form of technology for the Third World is an adapted, intermediate (less capital intensive) technology, founded around the needs of the people and utilizing readily available resources. When technology is used to relieve the symptoms of underdevelopment, a technologic misfit manifested in an overemphasis on prestige projects and the urban industrial sector results. Advanced communication technologies such as satellites are generally capital intensive, require high technical skills to install and maintain, and need sophisticated levels of management to function properly. These conditions are not easily met in the Third World, underscoring the need for intermediate technology as manifested in small and medium-sized business enterprises. Such an approach blends traditional technology, minimal capital, simple management structure, ample labor, and humane operation with the gains from sophisticated technology. Intermediate technology can serve as a good training ground for indigenous people in modern business methods and provide jobs for the unemployed. Most importantly, intermediate technology can function as an integral part of the larger society rather than as a loosely attached appendage grafted on by some foreign country. In the field of communication, such an approach would manifest itself in a willingness to operate professionally with simple portable cameras, an acceptance of the importance of rural radio broadcasting and village newspapers, a willingness on the part of trained media professionals to try out locally produced hardware, and an exploration of cheaper ways of producing textbooks.

  15. Failure Modes Effects and Criticality Analysis, an Underutilized Safety, Reliability, Project Management and Systems Engineering Tool

    Science.gov (United States)

    Mullin, Daniel Richard

    2013-09-01

    The majority of space programs whether manned or unmanned for science or exploration require that a Failure Modes Effects and Criticality Analysis (FMECA) be performed as part of their safety and reliability activities. This comes as no surprise given that FMECAs have been an integral part of the reliability engineer's toolkit since the 1950s. The reasons for performing a FMECA are well known including fleshing out system single point failures, system hazards and critical components and functions. However, in the author's ten years' experience as a space systems safety and reliability engineer, findings demonstrate that the FMECA is often performed as an afterthought, simply to meet contract deliverable requirements and is often started long after the system requirements allocation and preliminary design have been completed. There are also important qualitative and quantitative components often missing which can provide useful data to all of project stakeholders. These include; probability of occurrence, probability of detection, time to effect and time to detect and, finally, the Risk Priority Number. This is unfortunate as the FMECA is a powerful system design tool that when used effectively, can help optimize system function while minimizing the risk of failure. When performed as early as possible in conjunction with writing the top level system requirements, the FMECA can provide instant feedback on the viability of the requirements while providing a valuable sanity check early in the design process. It can indicate which areas of the system will require redundancy and which areas are inherently the most risky from the onset. Based on historical and practical examples, it is this author's contention that FMECAs are an immense source of important information for all involved stakeholders in a given project and can provide several benefits including, efficient project management with respect to cost and schedule, system engineering and requirements management

    ODM2 Admin is a tool to manage data stored in a relational database using the Observation Data Model 2 (ODM2) information model. Originally developed by the Luquillo Critical Zone Observatory (CZO) to manage a wide range of Earth observations, it has now been deployed at 6 projects: the Catalina Jemez CZO, the Dry Creek Experimental Forest, Au Sable and Manistee River sites managed by Michigan State, Tropical Response to Altered Climate Experiment (TRACE) and the Critical Zone Integrative Microbial Ecology Activity (CZIMEA) EarthCube project; most of these deployments are hosted on a Microsoft Azure cloud server managed by CUAHSI. ODM2 Admin is a web application built on the Python open-source Django framework and available for download from GitHub and DockerHub. It provides tools for data ingestion, editing, QA/QC, data visualization, browsing, mapping and documentation of equipment deployment, methods, and citations. Additional features include the ability to generate derived data values, automatically or manually create data annotations and create datasets from arbitrary groupings of results. Over 22 million time series values for more than 600 time series are being managed with ODM2 Admin across the 6 projects as well as more than 12,000 soil profiles and other measurements. ODM2 Admin links with external identifier systems through DOIs, ORCiDs and IGSNs, so cited works, details about researchers and earth sample meta-data can be accessed directly from ODM2 Admin. This application is part of a growing open source ODM2 application ecosystem under active development. ODM2 Admin can be deployed alongside other tools from the ODM2 ecosystem, including ODM2API and WOFpy, which provide access to the underlying ODM2 data through a Python API and Water One Flow web services.

  19. The Role of Oxytocin in Parenting and as Augmentative Pharmacotherapy: Critical Issues and Bold Conjectures.

    Despite the sometimes heated debate about the validity of human oxytocin studies, experimental oxytocin research with intranasal administration is a growing field with promising preliminary findings. The effects of intranasally administered oxytocin compared to placebo on brain neural activity have been supported in animal studies and in human studies of neural resting state. In several studies, oxytocin sniffs have been shown to lead to down-regulation of amygdala activation in response to infant attachment vocalisations. Meta-analytic evidence shows that oxytocin enhances the salience of (emotional) stimuli, lowers stress and arousal, and elevates empathic concern and tender care, in particular for offspring and in-group members. Less firm evidence points at the amnestic effects of oxytocin. We also note that the average effect sizes of oxytocin experiments are small to modest, and that most studies include a small number of subjects and thus are seriously underpowered, which implies a high risk for publication bias and nonreplicability. Nevertheless, we argue that the power of within-subjects experiments with oxytocin has been underestimated. Much more work is needed, however, to create a firm knowledge base of the neural and behavioural effects of oxytocin. Human oxytocin research is still taking place in the context of discovery, in which bold conjectures are being generated. In the context of justification, these conjectures should subsequently be subjected to stringent attempts at refutations before we jump to theoretical or clinical conclusions. For this context of justification, we propose a multisite multiple replications project on the social stimuli salience enhancing effect of oxytocin. Clinical application of oxytocin is premature. Meta-analytically, the use of oxytocin in clinical groups tends to show only effectiveness in changing symptomatology in individuals with autism spectrum disorders but, even then, it is not yet a validated therapy and its

    There are several contentious issues related to forestry mitigation projects. The special report of the IPCC and literature published so far have shown that permanence, leakage, baseline establishment, measurement, monitoring, etc., could be addressed satisfactorily using existing scientific methods and accounting rules. To understand the methodological issues of developing community forestry projects, a case study was conducted in Mancherial forest division of Adilabad district in Andhra Pradesh, India. This paper addresses: the setting of project boundaries, baseline selection, establishment of additionality and the calculation of carbon sequestration as a result of the project, prior to project implementation. The steps involved in development of the project and the different methods used for establishing baseline, estimating leakage and transaction cost of developing a community forestry project are presented. The stock is projected to increase by 1480 x 10 3 t C during 2000-2012 over the baseline scenario under the modeling approach and the cost of establishing a baseline and project formulation for a project extending over 32,956 ha is estimated to be US$ 1.25 ha -1 and US$ 4 t C -1

    Although, like the axilla, the internal mammary nodes (IMNs) are a first-echelon nodal drainage site in breast cancer, the importance of their treatment has long been debated. Seminal randomized trials have failed to demonstrate a survival benefit from surgical IMN dissection, and several retrospective studies have shown that IMNs are rarely the first site of recurrence. However, the recent widespread adoption of sentinel lymph node (SLN) biopsy has stimulated a critical reappraisal of such early results. Furthermore, the higher proportion of screening-detected cancers, improved imaging and techniques (i.e., lymphoscintigraphy for radioguided SLN biopsy) make it possible to visualize lymphatic drainage to the IMNs. The virtually systematic application of adjuvant systemic and/or loco-regional radiotherapy encourages re-examination of the significance of IMN metastases. Moreover, randomized trials testing the value of postmastectomy irradiation and a meta-analysis of 78 randomized trials have provided high levels of evidence that local-regional tumor control is associated with long-term survival improvements. This benefit was limited to trials that used systemic chemotherapy, which was not routinely administered in the earlier studies. However, the contribution from IMN treatment is unclear. Lymphoscintigraphic studies have shown that a significant proportion of breast cancers have primary drainage to the IMNs, including approximately 30% of medial tumors and 15% of lateral tumors. In the few studies where IMN biopsy was performed, 20% of sentinel IMNs were metastatic. The risk of IMN involvement is higher in patients with medial tumors and positive axillary nodes. IMN metastasis has prognostic significance, as recognized by its inclusion in the American Joint Committee on Cancer staging criteria, and seems to have similar prognostic importance as axillary nodal involvement. Although routine IMN evaluation might be indicated, it has not been routinely performed

    We review and compare four broad categories of spatially-explicit modelling approaches currently used to understand and project changes in the distribution and productivity of living marine resources including: 1) statistical species distribution models, 2) physiology-based, biophysical models of single life stages or the whole life cycle of species, 3) food web models, and 4) end-to-end models. Single pressures are rare and, in the future, models must be able to examine multiple factors affecting living marine resources such as interactions between: i) climate-driven changes in temperature regimes and acidification, ii) reductions in water quality due to eutrophication, iii) the introduction of alien invasive species, and/or iv) (over-)exploitation by fisheries. Statistical (correlative) approaches can be used to detect historical patterns which may not be relevant in the future. Advancing predictive capacity of changes in distribution and productivity of living marine resources requires explicit modelling of biological and physical mechanisms. New formulations are needed which (depending on the question) will need to strive for more realism in ecophysiology and behaviour of individuals, life history strategies of species, as well as trophodynamic interactions occurring at different spatial scales. Coupling existing models (e.g. physical, biological, economic) is one avenue that has proven successful. However, fundamental advancements are needed to address key issues such as the adaptive capacity of species/groups and ecosystems. The continued development of end-to-end models (e.g., physics to fish to human sectors) will be critical if we hope to assess how multiple pressures may interact to cause changes in living marine resources including the ecological and economic costs and trade-offs of different spatial management strategies. Given the strengths and weaknesses of the various types of models reviewed here, confidence in projections of changes in the

    The public institution aims to promote excellence in public management to contribute to the quality of services provided to its customers and to increase competitiveness in the country, as well as its international projection. A technical barrier to trade that can lead to dissatisfaction and achieve the reputation of the institution is failing the test or calibration results and measurement data, thereby accreditation is regarded as the first essential step to facilitate the mutual acceptance of test results and calibration or measurement data. For recognition, laboratories need to demonstrate full compliance with both the sections of ISO/IEC 17025:2005, i.e. management and technical requirements. This research aims to discuss the critical aspects for implementation of ABNT NBR ISO / IEC 17025:2005 for calibration and testing of a Public Institution seeking accreditation of its laboratories with INMETRO, national accreditation body Laboratories. Besides getting preventive, corrective and improvement actions continues guidelines. Furthermore, the methodology used was to conduct a literature search and apply a questionnaire to identify the degree of agreement / disagreement of the foundations of the standard servers. Analysis of the results showed that the critical issues were: commitment, training, resources (infrastructure, human) and culture. (author)

    Safety is a health issue and a significant concern in disadvantaged communities. This paper describes an example of community-initiated action to address perceptions of fear and safety in a suburb in south-west Sydney which led to the development of a local, community-driven research project. As a first step in developing community capacity to take action on issues of safety, a joint resident-agency group implemented a community safety mapping project to identify the extent of safety issues in the community and their exact geographical location. Two aerial maps of the suburb, measuring one metre by two metres, were placed on display at different locations for four months. Residents used coloured stickers to identify specific issues and exact locations where crime and safety were a concern. Residents identified 294 specific safety issues in the suburb, 41.9% (n=123) associated with public infrastructure, such as poor lighting and pathways, and 31.9% (n=94) associated with drug-related issues such as drug activity and discarded syringes. Good health promotion practice reflects community need. In a very practical sense, this project responded to community calls for action by mapping resident knowledge on specific safety issues and exact locations and presenting these maps to local decision makers for further action.

    The research project "Integrated System for Transport Infrastructure surveillance and Monitoring by Electromagnetic Sensing" (ISTIMES), was approved in the 7th Framework Programme, in the Joint Call ICT and Security and started on 1st July 2009. The purpose of ISTIMES project is to design, assess and promote an ICT-based system, exploiting distributed and local sensors, for non-destructive electromagnetic monitoring in order to achieve the critical transport infrastructures more reliable and safe. The transportation sector's components are susceptible to the consequences of natural disasters and can also be attractive as terrorist targets. The sector's size, its physically dispersed and decentralized nature, the many public and private entities involved in its operations, the critical importance of cost considerations, and the inherent requirement of convenient accessibility to its services by all users - make the transportation particularly vulnerable to security and safety threats. As well known, the surface transportation system consists of interconnected infrastructures including highways, transit systems, railroads, airports, waterways, pipelines and ports, and the vehicles, aircraft, and vessels that operate along these networks. Thus, interdependencies exist between transportation and nearly every other sector of the economy and the effective operation of this system is essential to the European economic productivity; therefore, transportation sector protection is of paramount importance since threats to it may impact other industries that rely on it. The system exploits an open network architecture that can accommodate a wide range of sensors, static and mobile, and can be easily scaled up to allow the integration of additional sensors and interfacing with other networks. It relies on heterogeneous state-of-the-art electromagnetic sensors, enabling a self-organizing, self-healing, ad-hoc networking of terrestrial sensors, supported by specific satellite

    2011-01-01

    In May 1973 the University of New Mexico conducted the first nationwide criticality safety training and education week-long short course for nuclear criticality safety engineers. Subsequent to that course, the Los Alamos Critical Experiments Facility (LACEF) developed very successful 'hands-on' subcritical and critical training programs for operators, supervisors, and engineering staff. Since the inception of the US Department of Energy (DOE) Nuclear Criticality Technology and Safety Project (NCT and SP) in 1983, the DOE has stimulated contractor facilities and laboratories to collaborate in the furthering of nuclear criticality as a discipline. That effort included the education and training of nuclear criticality safety engineers (NCSEs). In 1985 a textbook was written that established a path toward formalizing education and training for NCSEs. Though the NCT and SP went through a brief hiatus from 1990 to 1992, other DOE-supported programs were evolving to the benefit of NCSE training and education. In 1993 the DOE established a Nuclear Criticality Safety Program (NCSP) and undertook a comprehensive development effort to expand the extant LACEF 'hands-on' course specifically for the education and training of NCSEs. That successful education and training was interrupted in 2006 for the closing of the LACEF and the accompanying movement of materials and critical experiment machines to the Nevada Test Site. Prior to that closing, the Lawrence Livermore National Laboratory (LLNL) was commissioned by the US DOE NCSP to establish an independent hands-on NCSE subcritical education and training course. The course provided an interim transition for the establishment of a reinvigorated and expanded two-week NCSE education and training program in 2011. The 2011 piloted two-week course was coordinated by the Oak Ridge National Laboratory (ORNL) and jointly conducted by the Los Alamos National Laboratory (LANL) classroom education and facility training, the Sandia National

    This paper examines the potential for developing a more critical and reflexive curriculum around the sociology of health in nurse education. In Part One a review of the literature on Project 2000 to date suggests that insufficient attention has been paid to the scope for linking methodological and epistemological issues. it is argued that the status of 'andragogy' as a strategy of teaching and learning is ill-defined and that the nature of sociological theory in nurse education remains too crude and dichotomous to produce the 'knowledgeable doer', a qualitatively different kind of professional nurse practitioner.

    There is an important body of literature using multi-criteria distance function methods for the aggregation of a battery of sustainability indicators in order to obtain a composite index. This index is considered to be a proxy of the sustainability goodness of a natural system. Although this approach has been profusely used in the literature, it is not exempt from difficulties and potential pitfalls. Thus, in this paper, a significant number of critical issues have been identified showing different procedures capable of avoiding, or at least of mitigating, the inherent potential pitfalls associated with each one. The recommendations made in the paper could increase the theoretical soundness of the multi-criteria distance function methods when this type of approach is applied in the sustainability field, thus increasing the accuracy and realism of the sustainability measurements obtained.

    The KART (Kumatori Accelerator-driven Reactor Test facility) project started in Research Reactor Institute, Kyoto University in fiscal year 2002 with the grant by the Japanese Ministry of Education, Culture, Sports, Science and Technology. The purpose of this research project is to demonstrate the basis feasibility of accelerator driven system (ADS), studying the effect of incident neutron energy on the effective multiplication factor in a subcritical nuclear fuel system. For this purpose, a variable-energy FFAG (Fixed Field Alternating Gradient) accelerator complex is being constructed to be coupled with the Kyoto University Critical Assembly (KUCA). The FFAG proton accelerator complex consists of ion-beta, booster and main rings. This system aims to attain 1 μA proton beam with energy range from 20 to 150 MeV with a repetition rate of 120 Hz. The first beam from the FFAG complex is expected to be available by the end of FY 2005, and the experiment on ADS with KUCA and the FFAG complex (FFAG-KUCA experiment) will start in FY 2006. Before the FFAG-KUCA experiment starts, preliminary experiments with 14 MeV neutrons are currently being performed using a Cockcroft-Walton type accelerator coupled with the KUCA. Experimental data are analyzed using continuous energy Monte-Carlo codes MVP, MCNP and MNCP-X. (author)

    2015-01-01

    This critical review presents several aspects related to the use of copper as a main component in brake pads in road vehicles. The compositions of these materials are attracting increasing interest and concern due to the relative contribution of wear products to particulate matter emissions in the environment as a result of braking action even though there has been a reduction in exhaust products from internal combustion engines. We review the data on the main wear mechanisms in brake systems and highlight the positive role of copper. However, similar to other heavy metal emissions, even the release of copper into the atmosphere may have important environmental and health effects. Thus, several replacement strategies are being pursued, and the positive and negative features will be critically reviewed. Additionally, the future perspectives in materials development will be discussed. - Highlights: • Copper in brake pad materials: role and concerns. • Environmental and health impact of copper. • Copper replacement in frictional brake materials. • International legislation and standards on the above issues. - Importance of copper in brake pad materials and concern as regards environmental and health impact of its emission as brake wear product.

    Recent results from DIII-D address critical internal transport barrier (ITB) research issues relating to sustainability, impurity accumulation and ITB control, and have also demonstrated successful application of general profile control tools. In addition, substantial progress has been made in understanding the physics of the Quiescent Double Barrier (QDB) regime, increasing the demonstrated operating space for the regime and improving performance. Highlights include: (1) A clear demonstration of q-profile modification using electron cyclotron current drive (ECCD); (2) Successful use of localized profile control using electron cyclotron heating (ECH) or ECCD to reduce central high-Z impurity accumulation associated with density peaking; (3) Theory based modeling codes are now being used to design experiments; (4) The operating space for Quiescent H-mode (QH-mode) has been substantially broadened, in particular higher density operation has been achieved; (5) Both absolute (β≤ 3.8%, neutron rate S n ≤ 5.5x10 15 s -1 ) and relative (β N H 89 = 7 for 10τ E ) performance has been increased; (6) With regard to sustainment, QDB plasmas have been run for 3.8 s or 26 τ E . These results emphasize that it is possible to produce sustained high quality H-mode performance with an edge localized mode (ELM)-free edge, directly addressing a major issue in fusion research, of how to ameliorate or eliminate ELM induced pulsed divertor particle and heat loads.

    The increase in pulse duration and cumulative run-time, together with the increase of the plasma energy content, will represent the largest changes in operation conditions in future fusion devices such as the International Thermonuclear Experimental Reactor (ITER) compared to today's experimental facilities. These will give rise to important plasma-physics effects and plasma-material interactions (PMIs) which are only partially observed and accessible in present-day experiments and will open new design, operation and safety issues. For the first time in fusion research, erosion and its consequences over many pulses (e.g., co-deposition and dust) may determine the operational schedule of a fusion device. This paper identifies the most critical issues arising from PMIs which represent key elements in the selection of materials, the design, and the optimisation of plasma-facing components (PFCs) for the first-wall and divertor. Significant advances in the knowledge base have been made recently, as part of the R and D supporting the engineering design activities (EDA) of ITER, and some of the most relevant data are reviewed here together with areas where further R and D work is urgently needed

    Full Text Available Risks stemming from software projects were extensively studied. However, software project risk management has rarely researched organizational risks within multi-cultural and multi-ethnical atmospheres. The fact of the matter is that problems occur when the stakeholders’ cultural and ethnical aspects are not addressed, especially in multi-cultural, multi-ethnical, and cosmopolitan society such as Malaysia. To avoid analyzing something that has already been studied in detail, this study conducted based on in-depth literature review considering key word search in subject-specific databases. Journal articles published in reputed journals were reviewed. By employing Rumelt’s resistance to change checklist and culture gap tool source, this paper develops an organizational risk framework considering cross-cultural and cross-ethnical critical factors in order to show how can risks be better comprehended and managed. The significance of bio-cultural dimensions was scrutinized as vital criteria which should be considered in international project sphere, so that, not only the odds of project success would be increased but also the risks can be mitigated significantly. A review of the risk management process, Rumelt’s Checklist, cultural issues in international project environment allows a better understanding of the importance of cultural dimensions in project spheres.

    Full Text Available In this comment, the author reflects on surveillance from a critical theory approach, his involvement in surveillance research and projects, and the status of the study of surveillance. The comment ascertains a lack of critical thinking about surveillance, questions the existence of something called “surveillance studies” as opposed to a critical theory of society, and reflects on issues such as Edward Snowden’s revelations, and Foucault and Marx in the context of surveillance.

  1. Polyphenol-based nutraceuticals for the control of angiogenesis: Analysis of the critical issues for human use.

    2016-09-01

    Angiogenesis, the formation of new blood-vessel, is crucial in the pathogenesis of several diseases, and thus represents a druggable target for the prevention and treatment of different disorders. It is nowadays well kwon how diet can control cancer development and progression, and how the use of certain diet components can prevent cancer development. Several studies, also from our lab, now indicate that natural plant products including nutraceuticals modulate tumor angiogenesis. In this review, it is reported how phytochemicals, comprising hydroxytyrosol, resveratrol, genistein, curcumin, and the green tea component epigallocatechin-3-gallate among the others, negatively regulate angiogenesis. A single plant-derived compound may affect both endothelial and tumor cells, with the common denominator of anti-inflammatory and radical scavenger activities. Beside these positive features, documented in cellular and animal models, a series of critical issues should be considered from a pharmacological point of view as: what is the best source of bioactive compounds: food and beverages, extracted phytocomplexes, isolated nutraceuticals or synthetic analogues? How is the bioavailability of the compounds of interest in relation to the above source? Is there any biological activity by circulating metabolic derivatives? What is the best formulation, administration route and posology? How safe are in humans? How strong and reliable are the clinical trials designed for their use alone or in combination with conventional chemotherapy? After a dissertation of these critical points, the conclusion can be drawn that novel and effective strategies should be optimized to improve their bioavailability and efficacy, considering their exploitation as chemopreventive and/or curative approaches.

    2016-05-01

    Full Text Available Open Research has the potential to advance the scientific process by improving the transparency, rigour, scope and reach of research, but choosing to experiment with Open Research carries with it a set of ideological, legal, technical and operational considerations. Researchers, especially those in resource-constrained situations, may not be aware of the complex interrelations between these different domains of open practice, the additional resources required, or how Open Research can support traditional research practices. Using the Research on Open Educational Resources for Development (ROER4D project as an example, this paper attempts to demonstrate the interrelation between ideological, legal, technical and operational openness; the resources that conducting Open Research requires; and the benefits of an iterative, strategic approach to one’s own Open Research practice. In this paper we discuss the value of a critical approach towards Open Research to ensure better coherence between ‘open’ ideology (embodied in strategic intention and ‘open’ practice (the everyday operationalisation of open principles.

    The Cognitive and Emotional Health Project (CEHP) seeks to identify the demographic, social, and biological determinants of cognitive and emotional health in the older adult. As part of the CEHP, a critical evaluation study committee was formed to assess the state of epidemiological research on demographic, social, and biological determinants of cognitive and emotional health. Criteria for inclusion in the survey were large cohort studies, longitudinal in design, participants predominantly 65 years or older, with measurements of both cognition and emotion, and information on a wide variety of demographic, psychosocial, and biological factors. North American and European studies, which met these criteria, were selected for the review. Outcome measures included cognition, cognitive decline, and cognitive function. For emotion, symptoms included depression and anxiety, positive and negative affect, subjective well being, mastery, and resilience. Ninety-six papers were identified that addressed cognitive and emotional outcomes. A large variety of risk factors were consistently identified with cognitive outcomes, particularly those previously associated with increased risk of cardiovascular disease. There was considerable overlap between risk factors for cognitive and emotional outcomes. This review identifies a large number of lifestyle and health behaviors that alter the risk for maintenance of cognitive and emotional health. Large longitudinal cohort studies are a unique source to explore factors associated with cognitive and emotional health. Secondary analyses of these studies should be encouraged as should the development of standardized questionnaires to measure cognitive and emotional health. Future research in this field should study cognitive and emotional health simultaneously.

    Full Text Available We are coping more and more with the project and project management in day by day life. Even if some activities are the similarly with common organization actions, the life cycle project activities request more information and more actions. So it is necessary to have some tools, methods and rules to manage a large amount of information which must be disseminated to numerous stakeholders. This need could be solved by project management information systems (PMIS. PMIS is a complex one, with various components which are depending on type of project, type of organization etc. The latest evolution of information and communication technology was favorable to our research field. Therefore, there are different tools to support the structure, automation and efficiency of PMIS. Moreover from several years it is spread the following notions: web-based project management, project management office, enterprise project management. So, we can see the fast evolution of this field. But, our paper will bring general ideas relating to project management information systems, like definition of PMIS, the project life cycle and the information needed of each stage, various tools to support the PMIS procedures. The characteristics, tools, trends will be our future research.

  11. Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: A critical review.

    2017-04-01

    Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its wider commercial applicability. Recent advancements in bio-hydrometallurgy have suggested that these critical issues can be successfully alleviated through the addition of a catalyst. The catalyzing properties of a variety of metals ions (Ag + , Hg ++ , Bi +++ , Cu ++ , Co ++ etc.) during bioleaching have been successfully demonstrated. In this article, the role and mechanisms of these metal species in catalyzing bioleaching from different minerals (chalcopyrite, complex sulfides, etc.) and waste materials (spent batteries) are reviewed, techno-economic and environmental challenges associated with the use of metals ions as catalysts are identified, and future prospectives are discussed. Based on the analysis, it is suggested that metal ion-catalyzed bioleaching will play a key role in the development of future industrial bio-hydrometallurgical processes.

  12. Critical system issues and modeling requirements - the problem of beam energy sweep in an electron linear induction accelerator

    International Nuclear Information System (INIS)

    Turner, W.C.; Barrett, D.M.; Sampayan, S.E.

    1991-01-01

    In this paper the authors attempt to motivate the development of modeling tools for linear induction accelerator components by giving examples of performance limitations related to energy sweep. The most pressing issues is the development of an accurate model of the switching behavior of large magnetic cores at high dB/dt in the accelerator and magnetic compression modulators. Ideally one would like to have a model with as few parameters as possible that allows the user to choose the core geometry and magnetic material and perhaps a few parameters characterizing the switch model. Beyond this, the critical modeling tasks are: simulation of a magnetic compression modulator, modeling the reset dynamics of a magnetic compression modulator, modeling the loading characteristics of a linear induction accelerator cell, and modeling the electron injector current including the dynamics of feedback modulation and beam loading in an accelerator cell. Of course in the development of these models care should be given to benchmarking them against data from experimental systems. Beyond that one should aim for tools that have predictive power so that they can be used as design tools and not merely to replicate existing data

    Develop an effective First Aid's system in workplaces is significantly important to the outcomes of accidents at work, thus contributing positively to create healthy and safe environments, improving responsible attitude and risk perception by workers. The italian regulation (D. Lgs. 81/08; DM 388/03) gives an important role to First Aid within the system for managing health and safety in workplaces and requires the employers to designate and train workers and organize facilities in the workplace. However, to ensure that First Aid's system actually contributes to increasing health and safety in workplaces, it's necessary to verify its effectiveness, beyond the law compliance. The article stands to evaluate the critical issues and related innovations to be introduced in this context, by analyzing data from literature and field experiences involving actors in the prevention system. The goal is to provide suggestions and action proposals to improve first aid's system in workplaces, paying particular attention to the aiders training (selection, motivation, teaching methods, retraining), as well as introduce to innovations to allow an immediate and timely emergency response (company equipments, other useful devices). On this last aspect, it has given particular emphasis to the introduction of semi-automatic defibrillator (AED), which is essential in case of sudden cardiac arrest with ventricular fibrillation, and special aiders training by means of BLSD (Basic Life Support and Defibrillation) courses based on international guidelines.

  14. K25/K27 Characterization for Demonstrating Criticality Incredibility K-25 / K-27 D and D Project

    2008-01-01

    The K-25 and K-27 Buildings are currently undergoing decontamination and decommissioning (D and D) as part of a non-time critical removal action. When the enrichment process was shut-down, the process gas equipment and piping was purged to remove UF 6 , but the process gas system was not generally chemically treated to remove solid holdup. Generally, chemical treatment was completed it was not very effective in removing the larger deposits. Because of this, uranium deposits continue to reside throughout the process gas system. There is the potential for unreacted UF 6 to be present, as well. A key part of this project is to locate the remaining significant uranium deposits and manage them appropriately. Since some process gas components in the K-25 and K-27 Buildings contain enriched uranium holdup, it is important to ensure nuclear criticality safety during demolition or subsequent loading and transport of waste. Therefore, a major task in preparation for demolition is to demonstrate that 'criticality is incredible (CI)' in each building area. The U.S. Department of Energy (DOE) and Bechtel Jacobs Company LLC (BJC) are in agreement that proper and thorough characterization of fissile holdup material in the K-25 and K-27 process gas components is a key element in achieving and demonstrating that criticality is incredible, as well as in management of demolition wastes and collection of holdup material. While the classic project scheduling wisdom may indicate that performing all of the data quality objectives (DQO) and planning before the field work starts, the size of the K-25 / K-27 D and D Project combined with the evolving decommissioning plans and re-plans have indicated that a fresh look at what further characterization data are needed to meet the current project requirements. Performing a DQO in the middle of the project allowed a much greater degree of accuracy of the real project data needs than was possible even 22 months ago. The outcome of the DQO work

    A technical assessment of the critical issues and problem areas in the field of plasma materials interactions (PMI) in magnetic fusion devices shows these problems to be central for near-term experiments, for intermediate-range reactor devices including D-T burning physics experiments, and for long-term reactor machines. Critical technical issues are ones central to understanding and successful operation of existing and near-term experiments/reactors or devices of great importance for the long run, i.e., ones which will require an extensive, long-term development effort and thus should receive attention now. Four subgroups were formed to assess the critical PMI issues along four major lines: (1) PMI and plasma confinement physics experiments; (2) plasma-edge modelling and theory; (3) surface physics; and (4) materials technology for in-vessel components and the first wall. The report which follows is divided into four major sections, one for each of these topics

    Full Text Available This paper presents an architecture which applies document similarity measures to the documentation produced during the phases of software development in order to generate recommendations of process and people metrics for similar projects. The application makes a judgment of similarity of the Service Provision Offer (SPO document of a new proposed project to a collection of Project History Documents (PHD, stored in a repository of unstructured texts. The process is carried out in three stages: firstly, clustering of the Offer document with the set of PHDs which are most similar to it; this provides the initial indication of whether similar previous projects exist, and signifies similarity. Secondly, determination of which PHD in the set is most comparable with the Offer document, based on various parameters: project effort, project duration (time, project resources (members/size of team, costs, and sector(s involved, indicating comparability of projects. The comparable parameters are extracted using the GATE Natural Language Processing architecture. Lastly, a recommendation of metrics for the new project is made, which is based on the transferability of the metrics of the most similar and comparable PHD extracted, here referred to as recommendation.

    Full Text Available In this paper, we generally summarize the main issues in the operational period of water conservancy and hydropower projects in China over the past several decades. First, the adverse impacts of these projects since the technical guidelines were proposed in 2006 are analyzed. Then, combined with projects and experience from 2006 to 2014, the four main issues are summarized: (1 There exist many questions in the design and construction of fishways, which are useful for fish migration, and the migration effects are not as expected. (2 Temperature stratification affecting the downstream fish is the major impact of temperature, and alters fish spawning in the reproduction season. (3 Ecological base flow has been one of the primary questions of the last 30 years in China, the greatest related difficulty being quantification of the amount and flow process necessary to satisfy fish life history. (4 Fish habitat protection and restoration are popular topics in recent years with the development of river ecosystem restoration. Fish habitat loss due to the impacts of dam construction and habitat fragmentation has become more and more serious. These four issues are now the main difficulties in water project management, and interact with one another to bear combined effects on river ecosystems. The issues of eco-hydraulic consideration in the design period are the key factors. Finally, future priorities for research and practice of environmental protection for water conservancy and hydropower projects in China are proposed. The main purpose of this paper is to enhance the scientific research, monitoring, and assessment of operating effectiveness.

    Full Text Available During the International Year of Planet Earth (2007-2009, the Department of Earth Sciences of Turin University and a local Museum of Natural History promoted a project entitled, Understanding how the Earth works: from local situations to global processes. In this context, two geothematic exhibitions on the Cape Verde Archipelago were designed and staged in local museums. The exhibition called Getting to know a volcano in order to live with it was the subject of action research that involved the design of interactive activities and the analysis of data collected during guided tours conducted with students of different ages. This study allowed the demonstration of the effectiveness of teaching strategies in which relevant Earth sciences topics are proposed, like risk and sustainable development, thus stimulating debate among the students. This approach enhances the cultural experience of individuals by sharing it with other people. The aim was to widen their awareness of the cultural value of the territory, and to stimulate a new critical way of thinking about the Earth sciences. These didactic tools were further developed when they were proposed and pursued by experienced museum guides and teachers, who were able to involve not only institutions (museums and schools in the knowledge construction process, but also families, relatives and the local community.

  19. Global crop exposure to critical high temperatures in the reproductive period: historical trends and future projections

    2013-01-01

    Long-term warming trends across the globe have shifted the distribution of temperature variability, such that what was once classified as extreme heat relative to local mean conditions has become more common. This is also true for agricultural regions, where exposure to extreme heat, particularly during key growth phases such as the reproductive period, can severely damage crop production in ways that are not captured by most crop models. Here, we analyze exposure of crops to physiologically critical temperatures in the reproductive stage (T crit ), across the global harvested areas of maize, rice, soybean and wheat. Trends for the 1980–2011 period show a relatively weak correspondence (r = 0.19) between mean growing season temperature and T crit exposure trends, emphasizing the importance of separate analyses for T crit . Increasing T crit exposure in the past few decades is apparent for wheat in Central and South Asia and South America, and for maize in many diverse locations across the globe. Maize had the highest percentage (15%) of global harvested area exposed to at least five reproductive days over T crit in the 2000s, although this value is somewhat sensitive to the exact temperature used for the threshold. While there was relatively little sustained exposure to reproductive days over T crit for the other crops in the past few decades, all show increases with future warming. Using projections from climate models we estimate that by the 2030s, 31, 16, and 11% respectively of maize, rice, and wheat global harvested area will be exposed to at least five reproductive days over T crit in a typical year, with soybean much less affected. Both maize and rice exhibit non-linear increases with time, with total area exposed for rice projected to grow from 8% in the 2000s to 27% by the 2050s, and maize from 15 to 44% over the same period. While faster development should lead to earlier flowering, which would reduce reproductive extreme heat exposure for wheat on a

  1. Piercing the sovereign ceiling: Issues in oil and gas project financing

    International Nuclear Information System (INIS)

    Coleman, T.S.

    1998-01-01

    In the oil and gas sector, corporations and governments face huge capital spending requirements in order to transform large resource discoveries into producing, cash-generating assets. A significant portion of this funding is expected to be done on a project finance basis, where bank lenders or bond investors take a secured position in financing a discrete project, with the expectation of being paid back by the cash flows from that project after completion. This trend is increasing demand for crediting rating services to provide credit ratings for these project financings. A key challenge is to analyze and rate credit-worthy projects in countries that have relatively low foreign currency sovereign ceilings due to economic, political, and financial risks. In most cases, the credit ratings for projects financed in currencies outside the host country are capped at the country''s foreign currency ceiling. However, in a few instances, mainly in the oil and gas sector, Moody''s has pierced the foreign currency ceiling or rated certain projects above the sovereign ratings of the countries where they are domiciled. The purpose of this article is to briefly explain some of the qualitative factors and considerations that have allowed Moody''s to pierce the ceiling in the oil and gas sector, with a focus on two recent and noteworthy projects: Ras Laffan Liquefied Natural Gas in Qatar and Petrozuata in Venezuela

    1998-09-29

    In 1997, the SNFP developed a baseline change request (BCR) and submitted it to DOE-RL for approval. The schedule was formally evaluated to have a 19% probability of success [Williams, 1998]. In December 1997, DOE-RL Manager John Wagoner approved the BCR contingent upon a subsequent independent review of the new baseline. The SNFP took several actions during the first quarter of 1998 to prepare for the independent review. The project developed the Estimating Requirements and Implementation Guide [DESH, 1998] and trained cost account managers (CAMS) and other personnel involved in the estimating process in activity-based cost (ABC) estimating techniques. The SNFP then applied ABC estimating techniques to develop the basis for the December Baseline (DB) and documented that basis in Basis of Estimate (BOE) books. These BOEs were provided to DOE in April 1998. DOE commissioned Professional Analysis, Inc. (PAI) to perform a critical analysis (CA) of the DB. PAI`s review formally began on April 13. PAI performed the CA, provided three sets of findings to the SNFP contractor, and initiated reconciliation meetings. During the course of PAI`s review, DOE directed the SNFP to develop a new baseline with a higher probability of success. The contractor transmitted the new baseline, which is referred to as the High Probability Baseline (HPB), to DOE on April 15, 1998 [Williams, 1998]. The HPB was estimated to approach a 90% confidence level on the start of fuel movement [Williams, 1998]. This high probability resulted in an increased cost and a schedule extension. To implement the new baseline, the contractor initiated 26 BCRs with supporting BOES. PAI`s scope was revised on April 28 to add reviewing the HPB and the associated BCRs and BOES.

    The Department of Energy (DOE) has the responsibility to understand the ''big picture'' of worker health and safety which includes fully recognizing the vulnerabilities and associated programs necessary to protect workers at the various DOE sites across the complex. Exposure analysis and medical surveillance are key aspects for understanding this big picture, as is understanding current health and safety practices and how they may need to change to relate to future health and safety management needs. The exposure-based health issues project was initiated to assemble the components necessary to understand potential exposure situations and their medical surveillance and clinical aspects. Phase I focused only on current Hanford tank farm operations and serves as a starting point for the overall project. It is also anticipated that once the pilot is fully developed for Hanford HLW (i.e., current operations, retrieval, pretreatment, vitrification, and disposal), the process and analysis methods developed will be available and applicable for other DOE operations and sites. The purpose of this Phase I project report is to present the health impact information collected regarding ongoing tank waste maintenance operations, show the various aspects of health and safety involved in protecting workers, introduce the reader to the kinds of information that will need to be analyzed in order to effectively manage worker safety

    The concepts expressed in this paper concerns the activities to be developed within HEALTHLINE, a European project under the Telematics Application programme. HEALTHLINE is an umbrella project which takes initiatives and provides links to other international projects on health telematics. The projects involved are NIVEMES and RISE; they represent the starting point from which a common approach will be developed. The experience gained from these projects has highlighted two emerging requirements: information dissemination and training. To fulfil the needs of information, an Internet corner will be set up; it will allow citizens and health professionals to find and exchange information as well as to discuss themes concerning health care. Due to the most advanced technologies recently introduced, the Health care sector has had to modify its traditional ways of working to aid professionals in exploiting new training techniques and Health Care provision methods. HEALTHLINE will focus on training and on the development of the use of new tools and services. Furthermore, the project will exploit the training methodologies based on multimedia technology for developing training-on-the-job modules. The entire system, in its final stage, will consist of a network for co-operating training and information dissemination; European sites in the project will share information, training material and provide education and information on tele-health, medical and health-care issues to health care providers, beneficiaries and the general public.

    Du Randt, Francois Jean

    2014-08-01

    Full Text Available Projects that fail, for whatever reason, can impact negatively on society, organisations, and other stakeholders. A number of researchers have identified various critical success factors (CSFs that can influence the outcome and success of a project. This research therefore aims to determine the CSFs that influence various success measures of small- to medium-sized projects at a South African mining company, Exxaro Resources’ Grootegeluk Coal Mine. Other objectives of this research include determining the extent of the impacts of these CSFs on the different success measures of a project. The investigation suggests that there are correlations among CSFs, and that certain factors impact the outcome of projects far more than others. This research finds that the single most important CSF for small- to medium-sized projects is the selection of a competent project manager. The competent project manager is characterised by a group of interrelated CSF factors: good leadership, commitment, and learning from past experiences. Based on the research results, other CSFs are discussed and explored in order for recommendations to be made on how this mining company, and possibly other organisations, can achieve greater project success.

    Unconventional natural gas and oil resources in the United States are important components of a national energy program. While the Nation seeks greater energy independence and greener sources of energy, Federal agencies with environmental responsibilities, state and local regulators and water-resource agencies, and citizens throughout areas of unconventional shale gas development have concerns about the environmental effects of high volume hydraulic fracturing (HVHF), including those in the Appalachian Basin in the northeastern United States (fig. 1). Environmental concerns posing critical challenges include the availability and use of surface water and groundwater for hydraulic fracturing; the migration of stray gas and potential effects on overlying aquifers; the potential for flowback, formation fluids, and other wastes to contaminate surface water and groundwater; and the effects from drill pads, roads, and pipeline infrastructure on land disturbance in small watersheds and headwater streams (U.S. Government Printing Office, 2012). Federal, state, regional and local agencies, along with the gas industry, are striving to use the best science and technology to develop these unconventional resources in an environmentally safe manner. Some of these concerns were addressed in U.S. Geological Survey (USGS) Fact Sheet 2009–3032 (Soeder and Kappel, 2009) about potential critical effects on water resources associated with the development of gas extraction from the Marcellus Shale of the Hamilton Group (Ver Straeten and others, 1994). Since that time, (1) the extraction process has evolved, (2) environmental awareness related to high-volume hydraulic fracturing process has increased, (3) state regulations concerning gas well drilling have been modified, and (4) the practices used by industry to obtain, transport, recover, treat, recycle, and ultimately dispose of the spent fluids and solid waste materials have evolved. This report updates and expands on Fact Sheet 2009

  7. Planning and urbanistic projects – the non-author approach and issues of synergy in cooperation

    Directory of Open Access Journals (Sweden)

    Liljana Jankovič Grobelšek

    2005-01-01

    Full Text Available The article presents the non-author approach to urbanistic and planning projects. The project leader guides the entire project team, yet particular coordinators are also important. Contrary to authorship in architectural projects, in physical planning authorship is often or even always completely shared. Not only because planning projects can change significantly during adoption procedures, but mainly because there are many participating actors (designers, planners, commissioners and/or investors etc. that are involved in any project’s undertaking. Experience proves that the non-author approach is beneficial for good project management and creation of conditions for constructive cooperation within an interdisciplinary working group and with all the other contributing parties. Two tested examples are presented. Their comparison is very interesting, since the first example shows a project where good cooperation between the client, investor and designers, as well as willing interested public, conditioned quality improvements, while the second (because of the public and consequently against its interests diminished its quality significantly. Our judgement is that the quantity of the often mentioned necessity of public involvement is actually sufficient. There are no obstacles for public participation in urbanistic and physical planning, as long as the public is interested. Troubles are often triggered elsewhere – how to safeguard the common, public interest before particular publics (e.g. neighbours, the immediately affected etc..

  8. Pulse reshaping in photonic crystal waveguides and microcavities with Kerr nonlinearity: Critical issues for all-optical switching

    Vujic, Dragan; John, Sajeev

    2005-01-01

    We delineate critical issues for 'controlling light with light' in photonic crystal (PC) waveguides coupled to Kerr-nonlinear microresonators. These arise from (a) fundamental trade-off between switching speed and switching intensity threshold inherent in high-quality Q-factor cavities and (b) the dynamical nonlinear oscillation of such cavities in response to incident light pulses. Using finite-difference time-domain simulations of electromagnetic pulse propagation, we consider both (i) a nonlinear Fabry-Perot microresonator (embedded within a PC waveguide) exhibiting a narrow transmission resonance and (ii) a nonlinear point defect (side-coupled to a PC waveguide) exhibiting a narrow reflection spectrum. We describe self-induced switching from transmission to reflection induced by pulse intensity tuning as well as control of pulse transmission induced by the secondary, continuous (cw) laser field propagating through the same PC waveguide. For the Fabry-Perot microresonator, a well-defined self-switching threshold is obtained. However, this is accompanied by considerable temporal and spectral distortion of the pulse caused by the oscillatory nonlinear response of the microresonator. When the quality factor of the microresonator is increased, the switching intensity threshold can be lowered but the pulse transit (switching) time and the pulse distortion are increased. For the side-coupled microresonator, a gradual (not sharp) self-switching behavior as a function of incident intensity is obtained. For both the Fabry-Perot and side-coupled nonlinear microresonators, control of pulse transmission can be achieved by means of a secondary cw laser field. The cw power required for switching with realistic Kerr nonlinearities is in excess of 1 W/μm 2 and may cause optical damage to the semiconducting PC backbone. Both instantaneous and noninstantaneous Kerr-response models are considered. Our results underscore the limitations and trade-offs inherent in the possible

  9. APPLICABILITY OF A STRATEGIC MAP UNDER THE PERSPECTIVE OF CRITICAL FACTORS FOR PROJECT MANAGEMENT MATURITY AT A LARGE FINANCIAL INSTITUTION

    Sady Darcy da Silva Junior

    2012-01-01

    Full Text Available Project Management and Strategic Management are two subjects of major relevance within the corporate environment, despite usually being treated separately, at organizations. However, for Westphal et al. (2008 one of the ways to link project management and strategy is through project management maturity, and to this effect, a series of actions that can be characterized as critical factors (Rabechini Jr. & Pessoa, 2005 are required. Another way of seeking this connection is by means of the strategic map concept which, according to Kaplan and Norton (2004, p.10, “represents the lost link between strategy formulation and the execution of the strategy”. In this study the purpose is to evaluate the applicability of a strategic map, from a critical factors perspective, on project management maturity, as proposed by Silva Jr. and Luciano (2010. Thus a qualitative and exploratory approach case study was conducted at a large financial institution, where three interview scripts were applied on nine professionals, whereby three were leaders, three were project managers and three, functional managers. Furthermore, a graphical representation standard was designed picturing possible situations concerning the applicability of strategic objectives of the map proposed in the case under study. As a result, an important academic contribution to the vague and scarce literature on the relationship between project management and organizational strategy was verified, in addition to mapping possibilities of improvements for the organization, which otherwise might have been impossible to identify.

    Science.gov (United States)

    Xu, Xibao; Tan, Yan; Yang, Guishan

    2013-09-01

    The paper takes China's authoritative Environmental Impact Statement for the Yangzi (Yangtze) Three Gorges Project (TGP) in 1992 as a benchmark against which to evaluate emerging major environmental outcomes since the initial impoundment of the Three Gorges reservoir in 2003. The paper particularly examines five crucial environmental aspects and associated causal factors. The five domains include human resettlement and the carrying capacity of local environments (especially land), water quality, reservoir sedimentation and downstream riverbed erosion, soil erosion, and seismic activity and geological hazards. Lessons from the environmental impact assessments of the TGP are: (1) hydro project planning needs to take place at a broader scale, and a strategic environmental assessment at a broader scale is necessary in advance of individual environmental impact assessments; (2) national policy and planning adjustments need to react quickly to the impact changes of large projects; (3) long-term environmental monitoring systems and joint operations with other large projects in the upstream areas of a river basin should be established, and the cross-impacts of climate change on projects and possible impacts of projects on regional or local climate considered.

  1. Integrating a Procurement Management Process into Critical Chain Project Management (CCPM: A Case-Study on Oil and Gas Projects, the Piping Process

    Sung-Hwan Jo

    2018-05-01

    Full Text Available Engineering, Procurement, and Construction (EPC of oil and gas megaprojects often experience cost overruns due to substantial schedule delays. One of the greatest causes of these overruns is the mismanagement of the project schedule, with the piping works (prefabrication and installation occupying a majority of that schedule. As such, an effective methodology for scheduling, planning, and controlling of piping activities is essential for project success. To meet this need, this study used the Critical Chain Project Management (CCPM to develop a piping construction delay prevention methodology, incorporating material procurement processes for EPC megaprojects. Recent studies indicate that the traditional scheduling method used on oil and gas mega projects has critical limitations regarding resource scarcity, calculation of activity duration, and dealing with uncertainties. To overcome these limitations, the Theory of Constraints-based CCPM was proposed and implemented to provide schedule buffers management. Nonexistent in literature, and of critical importance, is this paper’s focus on the resource buffer, representing material uncertainty and management. Furthermore, this paper presents a step-by-step process and flow chart for project, construction, and material managers to effectively manage a resource buffer through the CCPM process. This study extends the knowledge of traditional resource buffers in CCPM to improve material and procurement management, thus avoiding the shortage of piping materials and minimizing delays. The resultant process was validated by both deterministic and probabilistic schedule analysis through two case studies of a crude pump unit and propylene compressor installation at a Middle Eastern Refinery Plant Installation. The results show that the CCPM method effectively handles uncertainty, reducing the duration of piping works construction by about a 35% when compared to the traditional method. Furthermore, the

    Reitinger, Elisabeth; Heimerl, Katharina

    2014-06-01

    The development of palliative care in nursing homes in German-speaking countries has gained in importance within the past 15-20 years. Ethical and gender issues are core aspects of a palliative care culture and should therefore be better understood. The aim of this study was to highlight insights regarding ethical and gender issues, based on the experiences of professionals in nursing homes. A 2-year participatory action research study was performed in collaboration with three nursing homes in Austria. The article focusses on 10 group discussions with interdisciplinary professional teams that were conducted to generate ethical narratives. Thematic and narrative analysis was undertaken both individually and within the interdisciplinary research team. Findings and interpretations were validated with practitioners and researchers. A total of 36 narratives were collected and summarised within eight themes concerning the theoretical journey of a nursing home resident with relatives from entry into the house until death. The most burdensome ethical dilemmas are not the ones around death and dying but rather those relating to small-scale everyday work/life issues. Sharing experiences and feelings in ethical discussions provides relief. Emotions are important facilitators of insight into ethical dilemmas. Gender issues can be observed in care situations as well as in the organisational structure of nursing homes. Opportunities to share experiences and perspectives around ethical questions in interdisciplinary group discussions help professionals to better understand difficult issues and find appropriate ways of managing them. There is a need for communication structures such as facilitated ethical discussions that enable nursing home staff to reflect their everyday decisions. Expression of emotions should be encouraged in ethical decision-making processes in nursing homes. Gender-sensitive reflection supports the development of palliative care as organisational culture.

    2016-11-12

    Engaging undergraduates in research is essential for teaching them to think like scientists, and it has become a desired component of classroom and laboratory instruction. Research projects that span an entire semester expose students to a variety of concepts and techniques and allow students to use experiments to learn scientific principles, understand why specific techniques are applicable, critically analyze varied data, and examine how experimentation leads to acquiring knowledge. To provide an experience with these features, a semester long research project was integrated into a combined lecture and laboratory course, Molecular Biology. The project utilized the zebrafish model to examine gene expression during embryonic development and required students to develop and test hypotheses about the timing of expression of previously uncharacterized genes. The main goals for the project were to provide opportunities for students to develop critical thinking skills required for conducting research and to support the content goals of the course. To determine whether these goals were met, student performance on the steps of the project and related pre-test and post-test questions was examined. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(6):565-573, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

    The Cervical and Breast Cancer Prevention (CECAP) Project sought to develop a national model for cervical cancer prevention in Indonesia based on visual inspection with acetic acid (VIA) to detect abnormal changes in the cervix. The purpose of this study was to evaluate a pilot project introducing VIA and cryotherapy in Indonesia and to identify lessons learned that could be applied to the national scale-up of cervical cancer prevention services. Fifty-four months (July 2007 to December 2011) of service records at 17 health centers were abstracted and analyzed. The data were used to calculate the proportion of all women aged 30-50 who received VIA screening, the VIA-positive rate, the treatment rate, and the interval between screening and treatment. The 45 050 women screened during the project included 24.4% of the total female population in the target age group in the catchment area. Throughout the 5-year project, 83.1% of VIA-positive women sought cryotherapy. During the last 18 months of the project, after data collection tools were revised to more accurately reflect when cryotherapy was received, 13% of women were treated on the same day that they were screened. Among the 74% of women treated within 1 month of screening, the mean interval between screening and treatment was 7.2 days. As cervical cancer prevention services are scaled up throughout Indonesia, changes in the service delivery model and program management are needed to increase screening coverage, promote a single-visit approach, and ensure the quality of services. © 2013 The Authors.

    The history and identity of the Avignon's bridge is inseparable from that of the Rhône river. Therefore, in order to share the history and memory of the Rhône, it is essential to get to know this bridge and especially to identify and make visible the traces of its past, its construction, its interaction with the river dynamics, which greatly influenced his life. These are the objectives of the PAVAGE project that focuses on digitally surveying, modelling and re-visiting a heritage site of primary importance with the aim of virtually restoring the link between the two sides which, after the disappearance of the Roman bridge of Arles, constituted for a long time the only connection between Lyon or Vienna and the sea. Therefore, this project has an important geo-historical dimension for which geo-morphological and paleoenvironmental studies were implemented in connection with the latest digital simulation methods exploiting geographic information systems. By integrating knowledge and reflections of archaeologists, historians, geomorphologists, environmentalists, architects, engineers and computer scientists, the result of this project (which involved 5 laboratories during 4 years) is a 3D digital model covering an extension of 50 km2 achieved by integrating satellite imagery, UAV-based acquisitions, terrestrial laser scanning and photogrammetry, etc. Beyond the actions of scientific valorisation concerning the historical and geomorphological dimensions of the project, the results of this work of this interdisciplinary investigation and interpretation of this site are today integrated within a location-based augmented reality application allowing tourists to exploring the virtual reconstruction of the bridge and its environment through tablets inside the portion of territory covered by this project (between Avignon and Villeneuve-lez-Avignon). This paper presents the main aspects of the 3D virtual reconstruction approach.

The document provides information on the problem areas that affect the design and operation of a steady state ETR or ITER type confinement device. It discusses both tokamaks and alternative concepts, and provides a survey of existing and planned confinement machines and laboratory facilities that can address the identified issues. A universal definition of steady state operation is difficult to obtain. From a physics point of view, steady state is generally achieved when the time derivatives approach zero and the operation time greatly exceeds the characteristic time constants of the device. Steady state operation for materials depends on whether thermal stress, creep, fatigue, radiation damage, or power removal are being discussed. For erosion issues, the fluence and availability of the machine for continuous operation are important, assuming that transient events such as disruptions do not limit the component lifetimes. The panel suggests, in general terms, that steady state requires plasma operation from 100 to 1000 seconds and an availability of more than a few percent, which is similar to the expectations for an ETR type device. The assessment of critical issues for steady state operation is divided into four sections: physics issues; technology issues; issues in alternative concepts; and devices and laboratory facilities that can address these problems.

    Full Text Available It should be pointed out that the dilemma of interruption and stoppage in the construction industry is a large-scale trend. Construction interruption and stoppage is considered one of the most recurring problems in the construction industry. Construction Interruption and stoppage is always measured as costly to all parties concerned in the projects and very often it will result in clash, claims, total desertion and much difficult for the feasibility and it slows the growth of construction sector. The objective of the research work that underpins this paper was to investigate the Factors and Consequences of construction projects on local contractors. A construction project is commonly acknowledged as successful when the aim of the project is achieved in terms of predetermined objectives that are mainly completed the project on time, within budget and specified quality in accordance with the specifications and to stakeholders’ satisfaction. One of the most important problems that may arise in the construction project is delays and the magnitude of these delays varies considerably from project to project. According to delay categories that were contractor related, client related, consultant related, labour related and external related, the study revealed the six major effects of delay that were time overrun, cost overrun, dispute, arbitration, total abandonment, and litigation.

    The former Rum Jungle uranium-copper project, Australia, is an internationally important case study on environmental pollution from and rehabilitation of mining. The Rum Jungle mining project is briefly reviewed, followed by a critical evaluation of monitoring data and pollution loads prior to and after rehabilitation - leading to the conclusion that rehabilitation has clearly failed the test of time after just two decades. The most critical findings are the need to understand pollution cycles holistically, and designing monitoring regimes to match, explicit inclusion of radiological criteria (lacking in original planning), and finally the need to set targets based on environmental criteria. Two examples include polluted groundwater which was excluded from rehabilitation and the poor design, construction and/or performance of engineered soil covers - both leading to increasing acid drainage impacts on the Finniss River. The critical review therefore presents a valuable case study of the environmental performance of uranium mine site rehabilitation. - The Rum Jungle U-Cu project underwent extensive rehabilitation in the 1980's, however, it remains a major cause of pollution to the Finniss River.

    Full Text Available This document presents the result of a qualitative action research developed with thirty-three third grade students at a public school in Bogota. This action research aimed at describing and analyzing the role of project work in the development of critical thinking in third grade efl students and to describe and document the way in which those students developed their writing skills through this methodology. The participants developed different inquiries related to topics they were interested in exploring and related to the recycling project of the school. The data were collected during eleven sessions carried out along eight months through field notes, artifacts, and audio recordings. The results show that through project work the students enhanced their emerging critical thinking skills and their writing process; improved their interactions with their classmates, discovered that learning English was something useful for their lives, and therefore they acquired more confidence in writing and speaking in English. Additionally, they became more reflective, organized and critical about what they think, what they say, and about what happens around them.

    Planning and permitting considerations for wind energy project siting in mountainous areas were discussed. Mountainous regions have a specific set of environmental and socio-economic concerns. Potential disruptions to wildlife, noise, and visual impacts are a primary concern in the assessment of potential wind farm projects. Alpine habitats are unique and often contain fragile and endangered species. Reclamation techniques for mountainous habitats have not been extensively tested, and the sites are not as resilient as sites located in other ecosystems. In addition, alpine habitats are often migratory corridors and breeding grounds for threatened or endangered birds. In the winter months, alpine habitats are used by caribou, grizzly bears, and wolverine dens. Bats are also present at high elevations. It is often difficult to conduct baseline and monitoring studies in mountainous areas since alpine habitat is subject to rapid weather changes, and has a very short construction period. tabs., figs.

    Full Text Available Antarctic subglacial lakes can represent extreme natural habitats for microorganisms from the position of their evolution and adaptation, as well as they can contain the information on Antarctic ice sheet history and climatic changes in their sediments. Now only direct measurements and sampling from these habitats can answer on many fundamental questions. Special precaution should be complied at penetration into these unique relic environments without unfavorable impacts and contamination. A number of recommendations were developed on levels of cleanliness and sterility during direct exploration and research of subglacial environments. Documents considered in the article are the first and necessary steps for appropriate and long-term ecological management of subglacial Antarctic environments. Today there are three projects of subglacial aquatic environment research which are in preparation and realization – the Russian project of Lake Vostok, the similar British project of Lake Ellsworth and the American project on Whillans Ice Stream. The programs of ecological stewardship for direct exploration of these lakes are discussed. All these subglacial aquatic objects of further exploration and research are so various on their structure, age and regime, that only results of all programs as a whole can help to draw us a uniform picture of a subglacial ecological system. Ecological stewardship of these should provide the minimal ecological impact with maximal scientific results. On the basis of existing documents and recommendations the general approaches and the program of ecological stewardship for Lake Vostok research are discussed. Study of drilling fluid, drilling chips, Vostok ice core and the fresh frozen water will allow to make an assessment of biological and chemical contamination as a result of the first penetration and to modify the further stewardship program for the second penetration and direct exploration of lake water.

    BENIPA (Bentonite Barriers in Integrated Performance Assessment) is a research project, within the Fifth Framework Programme of the European Union, which was started on September 2000 and is has a duration of 36 months. The overall objective of BENIPA is to assess the state of the art in the treatment of bentonite barriers in Integrated Performance Assessment, evaluating the capacity and consistency of methods and data available to convincingly justify the capacity of bentonite to perform their assigned safety functions. During the first part of the project different bentonite barrier concepts have been reviewed and four reference cases have been defined for the modelling work in the project. FEP's Databases have been created and the scientific and technical bases for the analysis of bentonite barriers have been reviewed. In the second part of the project. as a step previous to modelling, an analysis of models for the mechanical, hydrological, thermal and chemical conditions is carried out, along with a review of the needs in input data. In BENIPA, calculations at process and integrated level are currently being performed among different codes to check consistency and sufficiency or complementarity for fulfilling the needs of performance assessment. However, since it is too early to present some of the results or even the individual contributions of the partners, the modelling and calculations being currently carried out by ENRESA will be advanced, just as a representative example of the work going on. This paper summarises the work already done in BENIPA and provides with illustrations of the modelling work consisting of the approach followed by ENRESA in applying three codes: CODE-BRIGHT, CORE 2D and GOLDSIM. The processes considered, simplifications adopted, limitations imposed and preliminary findings of the work are mentioned along. (author)

  3. A preliminary examination of audience-related communications issues for the Hanford Environmental Dose Reconstruction Project

    1991-04-01

    The Hanford Environmental Dose Reconstruction (HEDR) Project will estimate radiation doses people may have received from exposure to radioactive materials released during past operations at the US Department of Energy's (DOE) Hanford Site near Richland, Washington. The HEDR Project was initiated in response to public concerns about possible health impacts from past releases of radioactive materials from Hanford. The TSP recognized early in the project that special mechanisms would be required to effectively communicate to the many different concerned audiences. Accordingly, the TSP directed PNL to examine methods for communicating causes and effects of uncertainties in the dose estimates. After considering the directive and discussing it with the Communications Subcommittee of the TSP, PNL undertook a broad investigation of communications methods to consider for inclusion in the TSP's current communications program. As part of this investigation, a literature review was conducted regarding risk communications. A key finding was that, in order to successfully communicate risk-related information, a thorough understanding of the knowledge level, concerns and information needs of the intended recipients (i.e., the audience) is necessary. Hence, a preliminary audience analysis was conducted as part of the present research. This report summarizes the results of this analysis. 1 ref., 9 tabs.

  4. Policies to Avoid Cost Overruns in Infrastructure Projects: Critical Evaluation and Recommendations

    2014-09-01

    Full Text Available Many infrastructure projects have cost overruns and there has been a lot of research both on why these cost overruns occur and what can be done to reduce hem. Bent Flyvbjerg is the leading researcher in the area and in this article his proposals are used as the starting point. Besides a literature review, a questionnaire was sent out to experienced Swedish project managers to find out what they thought could reduce cost overruns. The literature review and the questionnaire were the foundation for the proposals formulated in this article. Proposals concerned three areas: (1. Organisational macro-structure, e.g. using more PPP projects but also decentralisation of budgets where cost overruns in one project in a region lead to less alternative projects in the specific region. (2. Organisational quality: It should be easy to see when and where cost overruns occur and who was responsible. There should be a well-developed knowledge management system in the organisation and an organisation culture of openness with a focus on improvements. (3. Organisational processes, e.g. a systematic use of external reviewers in different stages of a project.   Keywords: Cost overruns, Infrastructure projects, Policy measures

  5. Criticality safety issues associated with the introduction of low void reactivity fuel in the Bruce reactors - a management and technical overview

    The concept of criticality for operating reactor staff, particularly in a natural uranium-fuelled reactor, is relatively benign - the reactor is controlled at the critical condition by the regulating system. That is, issues related to criticality exist only within the reactor, in a set of carefully managed circumstances. With the introduction of enriched Low Void Reactivity Fuel (LVRF) into this operating environment comes a new 'concept of criticality', one which, although physically the same, cannot be treated in the same fashion. It may be the case that criticality can be achieved outside the reactor, albeit with a set of very pessimistic assumptions. Such 'inadvertent criticality' outside the reactor, should it occur, cannot be controlled. The consequences of such an inadvertent criticality could have far-reaching effects, not only in terms of severe health effects to those nearby, but also in terms of the negative impact on Bruce Power, and the Canadian nuclear industry in general. Thus the introduction of LVRF in the Bruce B reactors, and therefore the introduction of this new hazard, inadvertent criticality, warrants the development of a governance structure for its management. Such a program will consist of various elements, including the establishment of a framework to administer the criticality safety program, analytical assessment to support the process design, the development of operational procedures, the development of enhanced emergency procedures if necessary, and the implementation of a criticality safety training program. The entire package must be sufficient to demonstrate to station management, and the regulator, that the criticality safety risks associated with the implementation of enriched fuel have been properly evaluated, and that all necessary steps have been taken to effectively manage these risks. A well-founded Criticality Safety Program will offer such assurance. In this paper, we describe the establishment of a Criticality Safety

    ENGLISH ABSTRACT: Transnet Freight Rail in South Africa has faced projects delays in its multi-project environment. This study takes South Africa as representative of developing countries, and develops the Critical Success Factors (CSFs model for multiple projects success, with the goal of expanding the conventional model by adding the demographic characteristics of the business units involved in the multiple projects. The empirical results showing the greatest number of success factors are people-related, with the focus on team selection and team commitment. Two demographic characteristics are of importance when managing multiple projects: the size of the business unit, and the employees’ project experience.

    AFRIKAANSE OPSOMMING: Transnet, ‘n spoorvragentiteit in Suid-Afrika, ondervind gereeld projekvertragings in hul multi-projekomgewing. Suid-Afrika, as ‘n voorbeeld van ontwikkelende lande, word in die studie gebruik en hierdie studie ontwikkel ‘n reeks suksesfaktore vir ‘n multi-projek-omgewing deur ‘n bestaande konvensionele model aan te pas om ook die demografiese eienskappe van die verskillende besigheidseenhede betrokke in die organisasie te inkorpo-reer. Die resultaat van die studie wys dat die grootste aantal suksesfaktore mens-geörienteerd is, met die fokus op die samestelling en toewyding van die betrokke projekspanne. Twee demografiese eienskape is belangrik by die bestuur van multi-projekte, naamlik die grootte van die besigheidseenheid asook projekondervinding van die werknemers.

    At 10:30 am, September 30th, 1999, a criticality accident occurred in a conversion building of a uranium processing plant in Tokai, Ibaraki prefecture. 69 people including 3 workers who then worked at the building, 3 fire fighters who dispatched to rescue them were exposed to the radiation. People with a 350 m-radius of the site were recommended to evacuate themselves from the region to a temporarily prepared evacuation center. And about one hundred thousand people within a 10 km-radius were also advised to stay inside of their home. Nuclear Safety Commission's Accident Investigation Committee is investigating causes of this accident and have been revealing that deviation from government-authorized processing method and negligence of its illegal procedure had contributed to the accident. The influence of this accident is expanding not only to the plant operating company, local people but also to Japanese nuclear power policy, the whole nuclear industry in Japan. Especially pervasion of 'Safety Culture' is strongly being required. This report analyses latent factors of some human behavior directly contributing to the criticality accident. It also mentions that 4 critical points on the poor climate for safety in the work place, the inadequate safety management, the unsuitable equipment and the production-biased company's policy are the latent factors of this accident. It also finds that the poor climate and the production-biased policy are the most important factors. It can be said that some people directly or indirectly having caused the accident are the victims of them. (author)

    The development and negotiation of an Engineering, Procurement and Construction (EPC) contract is a multi-disciplined and time consuming process. Relative to the first wave on new nuclear build projects of the 1950's - 1970's, today's EPC contracts are more complex for a variety of reasons including more demanding regulatory and environmental requirements, global supply chain versus localization issues and different world wide economic considerations. This paper discusses the impacts of some of these challenges on developing an EPC contract in today's Nuclear Renaissance. (authors)

    Undertaking research studies in the field of mental health is essential in mental health nursing. Qualitative research methodologies enable human experiences to become visible and recognize the importance of lived experiences. This paper argues that involving people with schizophrenia in research is critical to promote their health and well-being. The quality of qualitative research needs scrutinizing according to methodological issues such as trustworthiness and ethical standards that are a fundamental part of qualitative research and nursing curricula. The aim of this study was to critically review recent qualitative studies involving people with severe and persistent mental illness such as schizophrenia and other psychotic conditions, regarding descriptions of ethical and methodological issues in data collection and analysis. A search for relevant papers was conducted in three electronic databases, in December 2016. Fifteen qualitative interview studies were included and reviewed regarding methodological issues related to ethics, and data collection and analysis. The results revealed insufficient descriptions of methodology regarding ethical considerations and issues related to recruitment and sampling in qualitative interview studies with individuals with severe mental illness, putting trustworthiness at risk despite detailed descriptions of data analysis. Knowledge from the perspective of individuals with their own experience of mental illness is essential. Issues regarding sampling and trustworthiness in qualitative studies involving people with severe mental illness are vital to counteract the stigmatization of mental illness.

    Planning a new health sciences library at the beginning of the twenty-first century is a tremendous challenge. Technology has radically changed the way libraries function in an academic environment and the services they provide. Some individuals question whether the library as place will continue to exist as information becomes increasingly available electronically. To understand how libraries resolve programming and building design issues, visits were made to three academic health sciences libraries that have had significant renovation or completed new construction. The information gathered will be valuable for planning a new library for the University of Colorado Health Sciences Center and may assist other health sciences librarians as they plan future library buildings.

    Full Text Available After a disaster, the reconstruction phase is driven by immediate challenges. One of the main challenges in the post-disaster period is the way that reconstruction projects are implemented. Reconstruction cannot move forward until some complex issues are settled. The purposes of this research are to highlight the issues and challenges in post-disaster reconstruction (PDR projects and to determine the significant differences between the issues and challenges in different locations where PDR projects are carried out. The researchers collected data within international non-governmental organisations (INGOs on their experience of working with PDR projects. The findings of this research provide the foundation on which to build strategies for avoiding project failures; this may be useful for PDR project practitioners in the future.

    Quality assurance exercises and networking on the detection of highly infectious pathogens (QUANDHIP) is a joint action initiative set up in 2011 that has successfully unified the primary objectives of the European Network on Highly Pathogenic Bacteria (ENHPB) and of P4-laboratories (ENP4-Lab) both of which aimed to improve the efficiency, effectiveness, and response capabilities of laboratories directed at protecting the health of European citizens against high consequence bacteria and viruses of significant public health concern. Both networks have established a common collaborative consortium of 37 nationally and internationally recognized institutions with laboratory facilities from 22 European countries. The specific objectives and achievements include the initiation and establishment of a recognized and acceptable quality assurance scheme, including practical external quality assurance exercises, comprising living agents, that aims to improve laboratory performance, accuracy, and detection capabilities in support of patient management and public health responses; recognized training schemes for diagnostics and handling of highly pathogenic agents; international repositories comprising highly pathogenic bacteria and viruses for the development of standardized reference material; a standardized and transparent Biosafety and Biosecurity strategy protecting healthcare personnel and the community in dealing with high consequence pathogens; the design and organization of response capabilities dealing with cross-border events with highly infectious pathogens including the consideration of diagnostic capabilities of individual European laboratories. The project tackled several sensitive issues regarding Biosafety, Biosecurity and "dual use" concerns. The article will give an overview of the project outcomes and discuss the assessment of potential "dual use" issues.

    PISC II, the second stage of the Programme for the Inspection of Steel Components, was set up in 1980 to examine non-destructive techniques that could provide the desired level of capability for detection and sizing of defects to assure the integrity of critical structures such as pressure vessels. The objectives of the PISC-II programme, which comprises an experimental, round-robin test phase, are: to evaluate the effectiveness of NDT techniques either in use or being developed for the inspection of reactor pressure vessel components, with regard mainly to detecting and characterising service-induced flaws; to identify techniques for acceptance tests, pre-service inspection (PSI) and in-service inspection (ISI) which could be generally accepted; to bring the conclusions of the programme to the attention of the Code, Standard and Regulatory Bodies concerned with ISI. Performance of individual techniques, both manual and mechanized, is discussed and various types of defects considered. Conclusions are drawn on the detection and sizing capabilities of these techniques for each defect type

    Full Text Available This paper is based upon the research undertaken for the development of the doctoral thesis “Management of software projects based on object-oriented technology”. The study examines the existing risk management practices commonly used for classic software development. The goal is to integrate the elements of the traditional risk management methodologies to create a new agile risk management methodology. The thesis focuses on techniques that can be easily implemented in extreme programming (XP and SCRUM. This study is motivated by the following research questions: What are the elements of existing quality assurance tools that could meet the principles of agile development? And is it possible to use risk estimation for improving quality in agile projects? The thesis presents a synthesis of the most common risk management techniques, as well as an introduction to agile methods XP and SCRUM. The proposal integrates the concepts of Failure Mode and Effect Analysis into the iterative life cycle of an agile software project. The thesis presents a metamodel which integrates the concepts of agile development methodologies: SCRUM and XP with the FMEA concepts for risk quantification. The model was partly implemented into a real development project. Partial results show the improvement in early identification of failures and allowed to reconsider the Sprint plan.

  1. Assessing the Climate Impacts of Cookstove Projects: Issues in Emissions Accounting

    Directory of Open Access Journals (Sweden)

    Carrie M. Lee

    2014-03-01

    Full Text Available An estimated 2.6 billion people rely on traditional biomass for home cooking and heating, so improving the efficiency of household cookstoves could provide significant environmental, social and economic benefits. Some researchers have estimated that potential greenhouse gas emission reductions could exceed 1 billion tons of carbon dioxide equivalent (CO2e per year. Carbon finance offers a policy mechanism for realizing some of this potential and could also bring improved monitoring to cookstove projects. However, there are formidable methodological challenges in estimating emission reductions. This paper evaluates the quantification approaches to three key variables in calculating emission impacts: biomass fuel consumption, fraction of non-renewable biomass, and emission factors for fuel consumption. It draws on a literature review as well as on interviews with technical experts and market actors, and identifies lessons learned and knowledge gaps. Key research needs identified include incorporating accounting for uncertainty; development of additional default factors for biomass consumption for baseline stoves; refinement of monitoring approaches for cookstove use; broadened scope of emission factors used for cookstoves; accounting for non-CO2 gases and black carbon; and refinement of estimates and approaches to considering emissions from bioenergy use across methodologies.

    This critical review presents several aspects related to the use of copper as a main component in brake pads in road vehicles. The compositions of these materials are attracting increasing interest and concern due to the relative contribution of wear products to particulate matter emissions in the environment as a result of braking action even though there has been a reduction in exhaust products from internal combustion engines. We review the data on the main wear mechanisms in brake systems and highlight the positive role of copper. However, similar to other heavy metal emissions, even the release of copper into the atmosphere may have important environmental and health effects. Thus, several replacement strategies are being pursued, and the positive and negative features will be critically reviewed. Additionally, the future perspectives in materials development will be discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2018-05-01

    Albeit the understanding that construction waste is caused by activities ranging from all stages of project delivery process, research efforts have been concentrated on design and construction stages, while the possibility of reducing waste through materials procurement process is widely neglected. This study aims at exploring and confirming strategies for achieving waste-efficient materials procurement in construction activities. The study employs sequential exploratory mixed method approach as its methodological framework, using focus group discussion, statistical analysis and structural equation modelling. The study suggests that for materials procurement to enhance waste minimisation in construction projects, the procurement process would be characterised by four features. These include suppliers' commitment to low waste measures, low waste purchase management, effective materials delivery management and waste-efficient Bill of Quantity, all of which have significant impacts on waste minimisation. This implies that commitment of materials suppliers to such measures as take back scheme and flexibility in supplying small materials quantity, among others, are expected of materials procurement. While low waste purchase management stipulates the need for such measures as reduced packaging and consideration of pre-assembled/pre-cut materials, efficient delivery management entails effective delivery and storage system as well as adequate protection of materials during the delivery process, among others. Waste-efficient specification and bill of quantity, on the other hand, requires accurate materials take-off and ordering of materials based on accurately prepared design documents and bill of quantity. Findings of this study could assist in understanding a set of measures that should be taken during materials procurement process, thereby corroborating waste management practices at other stages of project delivery process.

    As a result of increasing recognition of effective site management as the strategic approach for achieving the required performance in construction projects, this study seeks to identify the key site management practices that are requisite for construction waste minimization. A mixed methods approach, involving field study and survey research were used as means of data collection. After confirmation of construct validity and reliability of scale, data analysis was carried out through a combination of Kruskal-Wallis test, descriptive statistics and exploratory factor analysis. The study suggests that site management functions could significantly reduce waste generation through strict adherence to project drawings, and by ensuring fewer or no design changes during construction process. Provision of waste skips for specific materials and maximisation of on-site reuse of materials are also found to be among the key factors for engendering waste minimization. The result of factor analysis suggests four factors underlying on-site waste management practices with 96.093% of total variance. These measures include contractual provisions for waste minimization, waste segregation, maximisation of materials reuse and effective logistic management. Strategies through which each of the underlying measures could be achieved are further discussed in the paper. Findings of this study would assist construction site managers and other site operatives in reducing waste generated by construction activities. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The aim of the CHANCE project is to develop novel and affordable nutritious foods to optimize the diet and reduce the risk of diet-related diseases among groups at risk of poverty (ROP). This paper describes the methodology used in the two initial steps to accomplish the project's objective as follows: 1. a literature review of existing data and 2. an identification of ROP groups with which to design and perform the CHANCE nutritional survey, which will supply new data that is useful for formulating the new CHANCE food. Based on the literature review, a low intake of fruit and vegetables, whole grain products, fish, energy, fiber, vitamins B1, B2, B3, B6, B12 and C, folate, calcium, magnesium, iron, potassium and zinc and a high intake of starchy foods, processed meat and sodium were apparent. However, the available data appeared fragmented because of the different methodologies used in the studies. A more global vision of the main nutritional problems that are present among low-income people in Europe is needed, and the first step to achieve this goal is the use of common criteria to define the risk of poverty. The scoring system described here represents novel criteria for defining at-risk-of-poverty groups not only in the CHANCE-participating countries but also all over Europe.

    The Department of Energy has hypothesized a number of alternate energy futures as part of its energy planning and analysis programs. How a proposed energy future called the Mid-Range Projection Series C Scenario would affect Federal Region VI (Arkansas, Louisiana, Oklahoma, Texas, and New Mexico) is examined in this report. This scenario assumes a medium supply and a medium demand for fuel through 1990, and it incorporates the fuel-switching provisions of the Energy Supply and Environmental Coordination Act. The report portrays the major regional environmental, human health and safety, socioeconomic, and institutional effects that might result from the realization of the Series C Scenario. This discussion should serve as a basis for further assessments, as it identifies some issues of major concern for Region VI that must be addressed in more depth.

    Quality assurance exercises and networking on the detection of highly infectious pathogens (QUANDHIP) is a joint action initiative set up in 2011 that has successfully unified the primary objectives of the European Network on Highly Pathogenic Bacteria (ENHPB) and of P4-laboratories (ENP4-Lab) both of which aimed to improve the efficiency, effectiveness, and response capabilities of laboratories directed at protecting the health of European citizens against high consequence bacteria and viruses of significant public health concern. Both networks have established a common collaborative consortium of 37 nationally and internationally recognized institutions with laboratory facilities from 22 European countries. The specific objectives and achievements include the initiation and establishment of a recognized and acceptable quality assurance scheme, including practical external quality assurance exercises, comprising living agents, that aims to improve laboratory performance, accuracy, and detection capabilities in support of patient management and public health responses; recognized training schemes for diagnostics and handling of highly pathogenic agents; international repositories comprising highly pathogenic bacteria and viruses for the development of standardized reference material; a standardized and transparent Biosafety and Biosecurity strategy protecting healthcare personnel and the community in dealing with high consequence pathogens; the design and organization of response capabilities dealing with cross-border events with highly infectious pathogens including the consideration of diagnostic capabilities of individual European laboratories. The project tackled several sensitive issues regarding Biosafety, Biosecurity and “dual use” concerns. The article will give an overview of the project outcomes and discuss the assessment of potential “dual use” issues. PMID:25426479

    The Fukushima Daiichi nuclear power plant accident on March 11, 2011 had a large impact both in and outside Japan, and is not yet concluded. After Tokyo Electric Power Co.'s (TEPCO's) Fukushima accident, electric power suppliers have taken measures to respond in the event that the same state of emergency occurs - deploying mobile generators, temporary pumps and hoses, and training employees in the use of this equipment. However, it is not only the “hard” problems including the design of equipment, but the “soft” problems such as organization and safety culture that have been highlighted as key contributors in this accident. Although a number of organizations have undertaken factor analysis of the accident and proposed issues to be reviewed and measures to be taken, a systematic overview about electric power suppliers' organization and safety culture has not yet been undertaken. This study is based on three major reports: the report by the national Diet of Japan Fukushima Nuclear Accident Independent Investigation Commission (the Diet report), the report by the Investigation Committee on the Accident at Fukushima Nuclear Power Stations of Tokyo Electric Power Company (Government report), and the report by the non-government committee supported by the Rebuild Japan Initiative Foundation (Non-government report). From these reports, the sections relevant to electric power suppliers' organization and safety culture were extracted. These sections were arranged to correspond with the prerequisites for the ideal organization, and 30 issues to be reviewed by electric power suppliers were extracted using brainstorming methods. It is expected that the identified issues will become a reference for every organization concerned to work on preventive measures hereafter. (author)

    General Atomics (GA) will be submitting an application for certification to the US Nuclear Regulatory Commission (NRC) for the GA-4 and GA-9 Casks In 1992. The GA-4 and GA-9 Casks are high-capacity legal weight truck casks designed to transport light water reactor spent fuel assemblies. To maintain a capacity of four pressurized-water-reactor (PWR) spent fuel assemblies, the GA-4 Cask uses burnup credit as part of the criticality control for initial enrichments over 3.0 wt% U-235. Using the US Department of Energy (DOE) Burnup Credit Program as a basis, GA has performed burnup credit analysis which is included in the Safety Analysis Report for Packaging (SARP). The GA-9 Cask can meet the criticality safety requirements using the ''fresh fuel'' assumption. Our approach to shielding design is to optimize the GA-4 and GA-9 Cask shielding configurations for minimum weights and maximum payloads. This optimization involves the use of the most effective shielding material, square cross-section geometry with rounded corners and tapered neutron shielding sections in the non-fuel regions

    Full Text Available A educação ambiental crítica e emancipatória exige que os conhecimentos sejam apropriados, construídos, de forma dinâmica, coletiva, cooperativa, contínua, interdisciplinar, democrática e participativa, voltados para a construção de sociedades sustentáveis. Este artigo trata dos temas ambientais como temas geradores para a educação ambiental, inspirados na pedagogia Paulo Freire, para quem educar é um ato de conhecimento da realidade concreta, das situações vividas, um processo de aproximação crítica da própria realidade: compreender, refletir, criticar e agir são as ações pedagógicas pretendidas. Os temas geradores são, portanto, estratégias metodológicas de um processo de conscientização da realidade opressora vivida nas sociedades desiguais; são o ponto de partida para o processo de construção da descoberta, e, por emergir do saber popular, os temas geradores são extraídos da prática de vida dos educandos, substituindo os conteúdos tradicionais e buscados através da pesquisa do universo dos educandos. O caráter político da pedagogia freireana faz-se presente, de forma radical, nos temas geradores, isto é, temas geradores só são geradores de ação-reflexão-ação se forem carregados de conteúdos sociais e políticos com significado concreto para a vida dos educandos. Assim, as propostas educativas ambientais conscientizadoras podem tomar os temas ambientais locais como temas geradores desta ação conscientizadora, desde que estes temas contenham conteúdos socioambientais significativos para os educandos e sejam definidos coletiva e participativamente.The emancipating and critical environmental education demands that knowledge must be adequate, build up in a dynamic, collective, cooperating, continuous, interdisciplinary, democratic and participating way directed to the construction of self-maintaining societies.

    Full Text Available Vertical cities’ growth is argument of discussion worldwide. Population increases and a better soil use are needed, in terms of efficiency and density, in many cities of the world. However, an excessive vertical growth seems to be harmful, especially near the green areas of midtowns. In this paper, the case of Antofagasta is studied. The paper studies different possible future evolutions searching for a bearable development, respecting the society needs and the environment. Parameters analyzed are: temperature, humidity, solar radiation, wind speed and direction in the studied area. Results show the impact of building growth in terms of overheating and wind reduction on the ground area studied. Additionally, the social impact of living in towers is also discussed in the paper, searching for better design in order to guarantee user’s comfort, satisfaction and stimulation in their residences. Thermal, visual and acoustical effects produced by towers are considered in the critical evaluation of the Antofagasta city evolution. Part of this work relates to architectural workshop “energy and architecture” conducted by the authors at the School of Architecture of the Catholic University of the North (UCN in 2012.

    2017-02-01

    Full Text Available Whilst the benefits of applying an industrialized building system (IBS have been well recognized globally in the construction industry, the application of IBS is particularly limited in developing countries such as China, and quality is considered one of the key issues affecting its application. This paper identifies a number of the key quality factors which present barriers to the promotion of IBS within the context of the Chinese construction industry. These include key factors such as “Inaccurate design of the connecting points between core components”, “Lack of design norms and standards for IBS components”, “Lack of quality criteria for IBS components”, “Lack of production norms and standards for IBS components”, “Lack of quality management system in production process”, and “Lack of technical guidelines for the construction of IBS projects”. The data used for analysis are derived from a comprehensive practical survey. The validity of the data is examined by using a statistical method. The findings from the study provide valuable references for formulating effective measures to mitigate the negative effects of these quality factors on IBS application in China, thereby ensuring that practice of the IBS system can be further developed within the country.

  20. Some Materials Degradation Issues in the U.S. High-Level Nuclear Waste Repository Study (The Yucca Mountain Project)

    2005-09-19

    The safe disposal of radioactive waste requires that the waste be isolated from the environment until radioactive decay has reduced its toxicity to innocuous levels for plants, animals, and humans. All of the countries currently studying the options for disposing of high-level nuclear waste (HLW) have selected deep geologic formations to be the primary barrier for accomplishing this isolation. In U.S.A., the Nuclear Waste Policy Act of 1982 (as amended in 1987) designated Yucca Mountain in Nevada as the potential site to be characterized for high-level nuclear waste (HLW) disposal. Long-term containment of waste and subsequent slow release of radionuclides into the geosphere will rely on a system of natural and engineered barriers including a robust waste containment design. The waste package design consists of a highly corrosion resistant Ni-based Alloy 22 cylindrical barrier surrounding a Type 316 stainless steel inner structural vessel. The waste package is covered by a mailbox-shaped drip shield composed primarily of Ti Grade 7 with Ti Grade 24 structural support members. The U.S. Yucca Mountain Project has been studying and modeling the degradation issues of the relevant materials for some 20 years. This paper reviews the state-of-the-art understanding of the degradation processes based on the past 20 years studies on Yucca Mountain Project (YMP) materials degradation issues with focus on interaction between the in-drift environmental conditions and long-term materials degradation of waste packages and drip shields within the repository system during the 10,000 years regulatory period. This paper provides an overview of the current understanding of the likely degradation behavior of the waste package and drip shield in the repository after the permanent closure of the facility. The degradation scenario discussed in this paper include aging and phase instability, dry oxidation, general and localized corrosion, stress corrosion cracking and hydrogen induced
