  3. Nanofluids Research: Key Issues

    PubMed Central

    2010-01-01

    Nanofluids are a new class of fluids engineered by dispersing nanometer-size structures (particles, fibers, tubes, droplets) in base fluids. The very essence of nanofluids research and development is to enhance fluid macroscopic and megascale properties such as thermal conductivity through manipulating microscopic physics (structures, properties and activities). Therefore, the success of nanofluid technology depends very much on how well we can address issues like effective means of microscale manipulation, interplays among physics at different scales and optimization of microscale physics for the optimal megascale properties. In this work, we take heat-conduction nanofluids as examples to review methodologies available to effectively tackle these key but difficult problems and identify the future research needs as well. The reviewed techniques include nanofluids synthesis through liquid-phase chemical reactions in continuous-flow microfluidic microreactors, scaling-up by the volume averaging and constructal design with the constructal theory. The identified areas of future research contain microfluidic nanofluids, thermal waves and constructal nanofluids. PMID:20676214

  4. Economic perspectives on key issues

    SciTech Connect

    Johnson, P.; Thomas, B.

    1985-01-01

    This book is about the contribution that economics can make to the understanding of some of today's key issues. The twelve topics discussed are representative of a very wide range of concerns. The first three chapters (on nuclear deterrence, the Palestinian problem, and sanctions against South Africa) are all issues associated with international relations. Later chapters consider the environment, poverty, technology, and the role of government. Family, crime, comprehensive education and youth unemployment issues are also addressed. All of the topics included illustrate issues which are of concern to many different societies. However, it is important to examine these issues in specific contexts rather than to rely on a purely general treatment using stylised facts. In a number of chapters the issues are therefore presented in the context of the UK and sometimes particular case studies are discussed.

  10. Versions to Address Business Process Flexibility Issue

    NASA Astrophysics Data System (ADS)

    Chaâbane, Mohamed Amine; Andonoff, Eric; Bouaziz, Rafik; Bouzguenda, Lotfi

    This paper contributes to address an important issue in business process management: the Business Process (BP) flexibility issue. First, it defends that versions are an interesting solution to deal with both a priori (when designing BPs) and a posteriori (when executing BPs) flexibility. It also explains why previous contributions about versions of BPs are incomplete, and need to be revisited. Then, the paper presents a meta-model for BP versions, which combines five perspectives -the functional, process, informational, organizational and operation perspectives- for BP modelling, and which allows a comprehensive description of versionalized BPs.

  11. Key issues in transplant tourism.

    PubMed

    Akoh, Jacob A

    2012-02-24

    Access to organ transplantation depends on national circumstances, and is partly determined by the cost of health care, availability of transplant services, the level of technical capacity and the availability of organs. Commercial transplantation is estimated to account for 5%-10% (3500-7000) of kidney transplants performed annually throughout the world. This review is to determine the state and outcome of renal transplantation associated with transplant tourism (TT) and the key challenges with such transplantation. The stakeholders of commercial transplantation include: patients on the waiting lists in developed countries or not on any list in developing countries; dialysis funding bodies; middlemen, hosting transplant centres; organ-exporting countries; and organ vendors. TT and commercial kidney transplants are associated with a high incidence of surgical complications, acute rejection and invasive infection which cause major morbidity and mortality. There are ethical and medical concerns regarding the management of recipients of organs from vendors. The growing demand for transplantation, the perceived failure of altruistic donation in providing enough organs has led to calls for a legalised market in organ procurement or regulated trial in incentives for donation. Developing transplant services worldwide has many benefits - improving results of transplantation as they would be performed legally, increasing the donor pool and making TT unnecessary. Meanwhile there is a need to re-examine intrinsic attitudes to TT bearing in mind the cultural and economic realities of globalisation. Perhaps the World Health Organization in conjunction with The Transplantation Society would set up a working party of stakeholders to study this matter in greater detail and make recommendations.

    ABSTRACT OBJECTIVE To assess the efficacy of a previsit questionnaire (PVQ), implemented without formal training, that was designed to screen for biomedical and psychosocial health issues and concerns among adolescent patients in a hospital-based primary care clinic, and to examine the subsequent action taken for health issues and concerns identified with the PVQ. DESIGN Retrospective review of adolescent medical charts, using a pre-post design. SETTING An outpatient primary care clinic located in an urban teaching hospital in Montreal, Que. PARTICIPANTS A total of 210 adolescent patients aged 13 to 19 who visited the clinic between 2000 and 2004. MAIN OUTCOME MEASURES The type (medical vs psychosocial) and number of issues detected and actions taken by physicians in one-to-one consultations with adolescent patients 2 years before (2000–2002) and 2 years after (2002–2004) PVQ implementation, as noted in the patients’ medical charts. RESULTS In total, 105 charts were reviewed for each group. An increase in the number of psychosocial issues was detected following the introduction of the PVQ. An increase in the frequency of action taken for psychosocial concerns and a decrease in the frequency of medical action taken by physicians were found after PVQ implementation. More notations related to psychosocial concerns were also found in the adolescents’ charts after introduction of the PVQ. CONCLUSION A PVQ is an effective strategy to improve adolescent screening for psychosocial issues and concerns. Implementing such a questionnaire requires no training and can therefore be easily incorporated into clinical practice. PMID:19602665

    1998-09-01

    This paper discusses secure architecture and protocols of managing Intellectual Property Rights in distributed content databases in a close environment. This discussion has been conducted within the European project AQUARELLE. This paper presents a short survey of watermarking technologies and focuses on functionalities offered by such techniques. We propose the terms of watermarking, fingerprinting and monitoring. For our implementation, we have worked with the Universite catholique de Louvain (UCL). This work is joint work with Jean-Francois Delaigle. Next we focus mainly on keys issues, and conclude that a trusted third party is needed to establish a verification service of watermarks. Next the DHWM key exchange is presented, based on the simple idea that watermarking and verification can be separated. This scheme uses the Diffie-Hellman key-exchange protocol. Next some hints on the implementation of the scheme and on its correctness are given.

  18. Key issues in plasma source ion implantation

    SciTech Connect

    Rej, D.J.; Faehl, R.J.; Matossian, J.N.

    1996-09-01

    Plasma source ion implantation (PSII) is a scaleable, non-line-of-sight method for the surface modification of materials. In this paper, we consider three important issues that should be addressed before wide-scale commercialization of PSII: (1) implant conformality; (2) ion sources; and (3) secondary electron emission. To insure uniform implanted dose over complex shapes, the ion sheath thickness must be kept sufficiently small. This criterion places demands on ion sources and pulsed-power supplies. Another limitation to date is the availability of additional ion species beyond B, C, N, and 0. Possible solutions are the use of metal arc vaporization sources and plasma discharges in high-vapor-pressure organometallic precursors. Finally, secondary electron emission presents a potential efficiency and x-ray hazard issue since for many metallurgic applications, the emission coefficient can be as large as 20. Techniques to suppress secondary electron emission are discussed.

    2016-04-01

    "Connectivity thinking" and related concepts have a long history in geomorphology. Since the beginning of the 21st century connectivity research experienced a huge boom in geomorphology as geomorphologists started to develop new concepts on connectivity to better understand the complexity of geomorphic systems and system response to change. However, progress in the field of connectivity in geomorphology has mostly been developing in a parallel manner, resulting in a multiplicity of definitions, concepts and methodological approaches. Nevertheless, a set of common key challenges amongst the different connectivity concepts and approaches used to understand complex geomorphic systems are also evident. In the course of a theory think tank of the COST Action ES1306 (CONNECTEUR - Connecting European Connectivity Research) the following five different key challenges were detected (Turnbull et al., in prep.): (i) defining the fundamental unit, (ii) distinguishing between structural and functional boundaries, (iii) emergent behavior, (iv) memory effects, (v) measuring connectivity. In this presentation we will a) discuss how these key challenges are addressed and approached in connectivity research in geomorphology, b) evaluate ways in which cross-disciplinary advances may be made by exploring potential for a common toolbox approach to the study of connectivity.

  1. Addressing security issues related to virtual institute distributed activities

    NASA Astrophysics Data System (ADS)

    Stytz, Martin R.; Banks, Sheila B.

    2008-03-01

    One issue confounding the development and experimentation of distributed modeling and simulation environments is the inability of the project team to identify and collaborate with resources, both human and technical, from outside the United States. This limitation is especially significant within the human behavior representation area where areas such as cultural effects research and joint command team behavior modeling require the participation of various cultural and national representatives. To address this limitation, as well as other human behavior representation research issues, NATO Research and Technology Organization initiated a project to develop a NATO virtual institute that enables more effective and more collaborative research into human behavior representation. However, in building and operating a virtual institute one of the chief concerns must be the cyber security of the institute. Because the institute "exists" in cyberspace, all of its activities are susceptible to cyberattacks, subterfuge, denial of service and all of the vulnerabilities that networked computers must face. In our opinion, for the concept of virtual institutes to be successful and useful, their operations and services must be protected from the threats in the cyber environment. A key to developing the required protection is the development and promulgation of standards for cyber security. In this paper, we discuss the types of cyber standards that are required, how new internet technologies can be exploited and can benefit the promulgation, development, maintenance, and robustness of the standards. This paper is organized as follows. Section One introduces the concept of the virtual institutes, the expected benefits, and the motivation for our research and for research in this area. Section Two presents background material and a discussion of topics related to VIs, uman behavior and cultural modeling, and network-centric warfare. Section Three contains a discussion of the

  2. Key technology issues for space robotic systems

    NASA Technical Reports Server (NTRS)

    Schappell, Roger T.

    1987-01-01

    Robotics has become a key technology consideration for the Space Station project to enable enhanced crew productivity and to maximize safety. There are many robotic functions currently being studied, including Space Station assembly, repair, and maintenance as well as satellite refurbishment, repair, and retrieval. Another area of concern is that of providing ground based experimenters with a natural interface that they might directly interact with their hardware onboard the Space Station or ancillary spacecraft. The state of the technology is such that the above functions are feasible; however, considerable development work is required for operation in this gravity-free vacuum environment. Furthermore, a program plan is evolving within NASA that will capitalize on recent government, university, and industrial robotics research and development (R and D) accomplishments. A brief summary is presented of the primary technology issues and physical examples are provided of the state of the technology for the initial operational capability (IOC) system as well as for the eventual final operational capability (FOC) Space Station.

    2015-01-01

    Given the widening gap between the number of individuals on transplant waiting lists and the availability of donated organs, as well as the recent plateau in donations based on neurological criteria (i.e., brain death), there has been a growing interest in expanding donation after circulatory determination of death. While the prevalence of this form of organ donation continues to increase, many thorny ethical issues remain, often creating moral distress in both clinicians and families. In this article, we address one of these issues, namely, the challenges surrounding patient and surrogate informed consent for donation after circulatory determination of death. First we discuss several general concerns regarding consent related to this form of organ donation, and then we address additional issues that are unique to three different patient categories: adult patients with medical decision-making capacity or potential capacity, adult patients who lack capacity, and pediatric patients.

  8. Nanotechnologies for Climate Friendly Construction - Key Issues and Challenges

    NASA Astrophysics Data System (ADS)

    Andersen, M. M.; Geiker, M. R.

    Expectations as to the climate potentials of nanotechnology are high, none the least related to the construction sector. This paper seeks to highlight key aspects in the early development and application of eco-innovative nanotech solutions in the construction sector, “nanoconstruction”. The paper provides a framework for addressing relevant issues of green nanoconstruction and takes stock of current challenges. Eco-innovative nanoconstruction has the potential to simultaneously enhance the competitiveness and climate potential of the construction sector and could become a key strategic factor for the sector ahead. However, the considerable lack of knowledge both on the eco-opportunities and risks of nanoconstruction and the industrial dynamics involved forms a serious barrier for pursuing nanoconstruction as a serious strategic target for business and policy.

    2015-10-01

    In response to a joint request from the World Climate Research Program's Climate and Cryosphere Project, the International Arctic Science Committee, and the Arctic Council's Arctic Monitoring and Assessment Program an updated scientific assessment has been conducted of the Arctic Freshwater System (AFS), entitled the Arctic Freshwater Synthesis (AFSΣ). The major reason behind the joint request was an increasing concern that changes to the AFS have produced, and could produce even greater, changes to biogeophysical and socioeconomic systems of special importance to northern residents and also produce extra-Arctic climatic effects that will have global consequences. The AFSΣ was structured around six key thematic areas: atmosphere, oceans, terrestrial hydrology, terrestrial ecology, resources, and modeling, the review of each coauthored by an international group of scientists and published as separate manuscripts in this special issue of Journal of Geophysical Research-Biogeosciences. This AFSΣ summary manuscript reviews key issues that emerged during the conduct of the synthesis, especially those that are cross-thematic in nature, and identifies future research required to address such issues.

  11. Extending the ARS Experimental Watersheds to Address Regional Issues

    NASA Astrophysics Data System (ADS)

    Marks, D.; Goodrich, D. C.; Winstral, A.; Bosch, D. D.; Pool, D.

    2001-12-01

    The USDA-Agricultural Research Service's (ARS) Watershed Research Program maintains and operates a diverse, geog raphically distributed, nested, multi-scale, national ex perimental watershed network. This network, much of which has been operational for more than 40 years (several more than 60 years), constitutes one the best networks of its kind in the world. The watershed network and its instrumentation was primarily established to assess the hydrologic impacts of watershed conservation and management practices. It has evolved, through development of long-term hydrologic data, as a network of high quality outdoor laboratories for addressing emerging science issues facing hydrologists and resource managers. While the value of the experimental watershed for investigating precipitation, climatic, and hydrologic processes is unquestioned, extending the results from these investigations to other sites and larger areas is more difficult. ARS experimental watersheds are a few hundred km2 or smaller making it challenging to address regional scale issues. To address this the ARS watershed program is, with a suite of partners from universities and other federal agencies, enlarging its research focus to extend beyond the boundaries of the experimental watershed. In this poster we present several examples of this effort, with suggestions on how, using the experimental watershed and its core, a larger scale hydrologic observatory could be developed and maintained.

    2014-01-01

    Background: The U.S. Environmental Protection Agency (EPA) completed a toxicological review of tetrachloroethylene (perchloroethylene, PCE) in February 2012 in support of the Integrated Risk Information System (IRIS). Objectives: We reviewed key findings and scientific issues regarding the human health effects of PCE described in the U.S. EPA’s Toxicological Review of Tetrachloroethylene (Perchloroethylene). Methods: The updated assessment of PCE synthesized and characterized a substantial database of epidemiological, experimental animal, and mechanistic studies. Key scientific issues were addressed through modeling of PCE toxicokinetics, synthesis of evidence from neurological studies, and analyses of toxicokinetic, mechanistic, and other factors (tumor latency, severity, and background rate) in interpreting experimental animal cancer findings. Considerations in evaluating epidemiological studies included the quality (e.g., specificity) of the exposure assessment methods and other essential design features, and the potential for alternative explanations for observed associations (e.g., bias or confounding). Discussion: Toxicokinetic modeling aided in characterizing the complex metabolism and multiple metabolites that contribute to PCE toxicity. The exposure assessment approach—a key evaluation factor for epidemiological studies of bladder cancer, non-Hodgkin lymphoma, and multiple myeloma—provided suggestive evidence of carcinogenicity. Bioassay data provided conclusive evidence of carcinogenicity in experimental animals. Neurotoxicity was identified as a sensitive noncancer health effect, occurring at low exposures: a conclusion supported by multiple studies. Evidence was integrated from human, experimental animal, and mechanistic data sets in assessing adverse health effects of PCE. Conclusions: PCE is likely to be carcinogenic to humans. Neurotoxicity is a sensitive adverse health effect of PCE. Citation: Guyton KZ, Hogan KA, Scott CS, Cooper GS, Bale AS

    1996-12-01

    The mission of the U.S. Nuclear Regulatory Commission (NRC) is to ensure the safe design, construction, and operation of commercial nuclear power plants and other facilities in the U.S.A. One of the main roles that the Office of Nuclear Regulatory Research (RES) plays in achieving the NRC mission is to plan, recommend, and implement research programs that address safety and technical issues deemed important by the NRC. The results of the research activities provide the bases for developing NRC positions or decisions on these issues. Also, RES performs confirmatory research for developing the basis to evaluate industry responses and positions on various regulatory requirements. This presentation summarizes some recent RES supported research activities that have addressed safety and technical issues related to valves and pumps. These activities include the efforts on determining valve and motor-operator responses under dynamic loads and pressure locking events, evaluation of monitoring equipment, and methods for detecting and trending aging of check valves and pumps. The role that RES is expected to play in future years to fulfill the NRC mission is also discussed.

  17. Introduction: the need to address older women's mental health issues.

    PubMed

    Malatesta, Victor J

    2007-01-01

    Women are the primary consumers of mental health services. Ironically, research addressing their unique needs lags behind that of men's issues. The aging process introduces an important variable that accentuates the relative lack of information and specific treatment guidelines for older women who are confronted by mental health problems. This volume offers a comprehensive overview for the health professional who is seeking a greater depth of understanding with respect to the study of mental health problems in general, and how these issues pertain specifically to women and the aging process. A second goal of this project is to provide the practicing therapist and counselor with a research update and a broad clinical perspective offered by seasoned clinicians. Using current psychiatric diagnosis as a framework, the contributions address the range of mental health problems, including dementia and cognitive impairment, schizophrenia, alcohol abuse, mood and anxiety disorders, traumatic and dissociative conditions, sexual and eating disorders, and personality disorders. It is hoped that this book will inform, inspire and encourage students and health professionals in their work with middle aged and older women who are facing mental health challenges. PMID:17588876

    1991-01-01

    The future appears rich in missions that will extend the frontiers of knowledge, human presence in space, and opportunities for profitable commerce. Key to the success of these ventures is the availability of plentiful, cost effective electric power and assured, low cost access to space. While forecasts of space power needs are problematic, an assessment of future needs based on terrestrial experience has been made. These needs fall into three broad categories: survival, self sufficiency, and industrialization. The cost of delivering payloads to orbital locations from LEO to Mars has been determined and future launch cost reductions projected. From these factors, then, projections of the performance necessary for future solar and nuclear space power options has been made.

    Risk analysis of key systems have become a growing topic late of because of the development of offshore structures. Equipment failures of offloading system and fire accidents were analyzed based on the floating production, storage and offloading (FPSO) features. Fault tree analysis (FTA), and failure modes and effects analysis (FMEA) methods were examined based on information already researched on modules of relex reliability studio (RRS). Equipment failures were also analyzed qualitatively by establishing a fault tree and Boolean structure function based on the shortage of failure cases, statistical data, and risk control measures examined. Failure modes of fire accident were classified according to the different areas of fire occurrences during the FMEA process, using risk priority number (RPN) methods to evaluate their severity rank. The qualitative analysis of FTA gave the basic insight of forming the failure modes of FPSO offloading, and the fire FMEA gave the priorities and suggested processes. The research has practical importance for the security analysis problems of FPSO.

    In developing a national strategy for the disposal of radioactive wastes, each country will consider isolation options that are appropriate to the types of waste that are produced. The options are developed in response to specific national regulatory requirements, and thus will focus on different aspects of performance. However, there are a number of technical concerns that are common to all programmes. The major issues concerning the behavior of the chemical and physical barriers in the near field of a radioactive waste repository are discussed in this paper. The description of key issue has been divided into the following categories: barrier design, barrier evolution, scientific understanding through modelling, and validation of performance. The near-field barriers are selected and designed to provide appropriate radionuclide containment and control. Factors affecting the evolution of these barriers, such as container degradation and gas generation, determine the subsequent release of radionuclides to the human environment. Modelling repository evolution is therefore an integral feature of performance assessments, and issues such as the treatment of inhomogeneities and non-equilibrium chemistry may need to be addressed. However, the use of mathematical and computer models implies a requirement for validation. The use of demonstration experiments and natural analogues builds confidence in the predictions of repository performance models, and provides a degree of validation for otherwise inaccessible timescales.

  1. Ethnocentric approach to address South Asian health issues.

    PubMed

    Sharif, A

    2012-09-01

    South Asian populations have distinct healthcare requirements to other ethnic demographics. Epidemiologically they constitute a high-risk group for many public health diseases such as cardiovascular disease, chronic kidney disease and diabetes mellitus. Despite individuals of South Asian backgrounds encompassing many individual countries, cultures, religions and backgrounds they share many common health concerns that are poorly tackled in established models of healthcare delivery. To successfully address this burgeoning public health burden, it is important for healthcare professionals and providers to appreciate the need for an ethnocentric approach to South Asian health requirements. Key stakeholders need to understand the need for an integrated ethnocentric approach to challenge the poor health status of this population. Appreciation of the socio-cultural dimension to South Asian healthcare requirements should help guide targeted and focused strategies to improve the outlook for this unique population at high public health risk.

    The goal of the Western Wind Strategy project was to help remove critical barriers to wind development in the Western Interconnection. The four stated objectives of this project were to: (1) identify the barriers, particularly barriers to the operational integration of renewables and barriers identified by load-serving entities (LSEs) that will be buying wind generation, (2) communicate the barriers to state officials, (3) create a collaborative process to address those barriers with the Western states, utilities and the renewable industry, and (4) provide a role model for other regions. The project has been on the forefront of identifying and informing state policy makers and utility regulators of critical issues related to wind energy and the integration of variable generation. The project has been a critical component in the efforts of states to push forward important reforms and innovations that will enable states to meet their renewable energy goals and lower the cost to consumers of integrating variable generation.

    2015-01-01

    Background: Static nature of performance reporting systems in health care sector has resulted in inconsistent, incomparable, time consuming, and static performance reports that are not able to transparently reflect a round picture of performance and effectively support healthcare managers’ decision makings. So, the healthcare sector needs interactive performance management tools such as performance dashboards to measure, monitor, and manage performance more effectively. The aim of this article was to identify key issues that need to be addressed for developing high-quality performance dashboards in healthcare sector. Methods: A literature review was established to search electronic research databases, e-journals collections, and printed journals, books, dissertations, and theses for relevant articles. The search strategy interchangeably used the terms of “dashboard”, “performance measurement system”, and “executive information system” with the term of “design” combined with operator “AND”. Search results (n=250) were adjusted for duplications, screened based on their abstract relevancy and full-text availability (n=147) and then assessed for eligibility (n=40). Eligible articles were included if they had explicitly focused on dashboards, performance measurement systems or executive information systems design. Finally, 28 relevant articles included in the study. Results: Creating high-quality performance dashboards requires addressing both performance measurement and executive information systems design issues. Covering these two fields, identified contents were categorized to four main domains: KPIs development, Data Sources and data generation, Integration of dashboards to source systems, and Information presentation issues. Conclusion: This study implies the main steps to develop dashboards for the purpose of performance management. Performance dashboards developed on performance measurement and executive information systems principles and

    2012-01-01

    Background: In support of the Integrated Risk Information System (IRIS), the U.S. Environmental Protection Agency (EPA) completed a toxicological review of trichloroethylene (TCE) in September 2011, which was the result of an effort spanning > 20 years. Objectives: We summarized the key findings and scientific issues regarding the human health effects of TCE in the U.S. EPA’s toxicological review. Methods: In this assessment we synthesized and characterized thousands of epidemiologic, experimental animal, and mechanistic studies, and addressed several key scientific issues through modeling of TCE toxicokinetics, meta-analyses of epidemiologic studies, and analyses of mechanistic data. Discussion: Toxicokinetic modeling aided in characterizing the toxicological role of the complex metabolism and multiple metabolites of TCE. Meta-analyses of the epidemiologic data strongly supported the conclusions that TCE causes kidney cancer in humans and that TCE may also cause liver cancer and non-Hodgkin lymphoma. Mechanistic analyses support a key role for mutagenicity in TCE-induced kidney carcinogenicity. Recent evidence from studies in both humans and experimental animals point to the involvement of TCE exposure in autoimmune disease and hypersensitivity. Recent avian and in vitro mechanistic studies provided biological plausibility that TCE plays a role in developmental cardiac toxicity, the subject of substantial debate due to mixed results from epidemiologic and rodent studies. Conclusions: TCE is carcinogenic to humans by all routes of exposure and poses a potential human health hazard for noncancer toxicity to the central nervous system, kidney, liver, immune system, male reproductive system, and the developing embryo/fetus.

    The proper characterization of Hazardous, Mixed Low-Level, and Mixed Transuranic waste enhances productivity and safety. Hazardous material criteria that need to be considered include physical and health hazards inherent to the waste stream. Other factors that may influence characterization include: particulate diameter, complexing or chelating agent properties, lead, and mercury content, pressurized containers, and P-listed wastes. To meet these requirements are only a simple matter of generating a database with the proper fields. Manufactures and institutional databases bank huge sources of information, such as, work control documents, substance identification, container types, components of mixtures, physical property data, and regulatory data. In this report, utilization of commercially available software programs to take advantage of these resources in addressing waste characterization issues are presented. The application of user-friendly programs eliminates part of the tediousness associated with the complex requirements of certifying to general waste acceptance criteria with minimal impact on programmatic work. In other words, tapping into manufacturer and institutional database provides a way to take advantage of the combined expertise of these resources in managing a cost effective waste certification program as well as adding a quality assurance element to the program.

    1999-03-01

    Today, most fuzzy logic operations are performed via software means, which is inevitably slow. While searching for long term hardware solutions to realize analog fuzzy logic operations, the use of the well-developed Boolean logic hardware with analog to digital and digital to analog converters to implement the digitized fuzzy logic could provide an efficient solution. Similar to Boolean logic, digitized fuzzy logic operations can be written as a minimized sum-of-product term format, which can then be implemented based on programmable logic arrays. We address a fundamental issue of the computational complexity of this method. We derive the minimum number of the Boolean sum-of-product terms for some key fuzzy logic operations, such as Union, Intersection, and Complement operators. Our derivations provide ways to estimate the general computational complexity or memory capacity of using binary circuits, electronic or optoelectronic, to implement the digitized analog logic operations.

    2016-06-01

    For many years, attention-deficit hyperactivity disorder (ADHD) was thought to be a childhood-onset disorder that has a limited effect on adult psychopathology. However, the symptoms and impairments that define ADHD often affect the adult population, with similar responses to drugs such as methylphenidate, dexamphetamine, and atomoxetine, and psychosocial interventions, to those seen in children and adolescents. As a result, awareness of ADHD in adults has rapidly increased and new clinical practice has emerged across the world. Despite this progress, treatment of adult ADHD in Europe and many other regions of the world is not yet common practice, and diagnostic services are often unavailable or restricted to a few specialist centres. This situation is remarkable given the strong evidence base for safe and effective treatments. Here we address some of the key conceptual issues surrounding the diagnosis of ADHD relevant to practising health-care professionals working with adult populations. We conclude that ADHD should be recognised in the same way as other common adult mental health disorders, and that failure to recognise and treat ADHD is detrimental to the wellbeing of many patients seeking help for common mental health problems.

    2007-03-01

    The Editorial Board of Reports on Progress in Physics has commissioned a series of short articles from world leaders on key physics issues in their field. These essays may raise the key issues, or ask open questions or may even suggest wild ideas. Basically, they give world leading physicists the opportunity to write what they think about the key issues in their field, free from the usual requirement to provide the fair and balanced presentations of the subject normally found in articles in Reports on Progress in Physics. We believe that the readers of the journal will be interested to learn about these exciting ideas. Just as Hilbert's famous paper of 1900 set the agenda for the next century or more in mathematics, so we hope that this series of papers will define the key issues and open questions in physics for the 21st Century and that the articles will be widely cited and downloaded. The first of these articles—'Insights from simulations of star formation' by Richard B Larson (Yale University, USA)—is published in the current issue. We trust that readers will find this article and its successors in the series to appear through 2007 and beyond entertaining and stimulating.

    Advanced human-system interface (HSI) technology is being integrated into existing nuclear plants as part of plant modifications and upgrades. The result of this trend is that hybrid HSIs are created, i.e., HSIs containing a mixture of conventional (analog) and advanced (digital) technology. The purpose of the present research is to define the potential effects of hybrid HSIs on personnel performance and plant safety and to develop human factors guidance for safety reviews of them where necessary. In support of this objective, human factors issues associated with hybrid HSIs were identified. The issues were evaluated for their potential significance to plant safety, i.e., their human performance concerns have the potential to compromise plant safety. The issues were then prioritized and a subset was selected for design review guidance development.

  17. Gender Differences in Cancer Susceptibility: An Inadequately Addressed Issue

    PubMed Central

    Dorak, M. Tevfik; Karpuzoglu, Ebru

    2012-01-01

    The gender difference in cancer susceptibility is one of the most consistent findings in cancer epidemiology. Hematologic malignancies are generally more common in males and this can be generalized to most other cancers. Similar gender differences in non-malignant diseases including autoimmunity, are attributed to hormonal or behavioral differences. Even in early childhood, however, where these differences would not apply, there are differences in cancer incidence between males and females. In childhood, few cancers are more common in females, but overall, males have higher susceptibility. In Hodgkin lymphoma, the gender ratio reverses toward adolescence. The pattern that autoimmune disorders are more common in females, but cancer and infections in males suggests that the known differences in immunity may be responsible for this dichotomy. Besides immune surveillance, genome surveillance mechanisms also differ in efficiency between males and females. Other obvious differences include hormonal ones and the number of X chromosomes. Some of the differences may even originate from exposures during prenatal development. This review will summarize well-documented examples of gender effect in cancer susceptibility, discuss methodological issues in exploration of gender differences, and present documented or speculated mechanisms. The gender differential in susceptibility can give important clues for the etiology of cancers and should be examined in all genetic and non-genetic association studies. PMID:23226157

    Global climate change is a high priority issue for the electric utility industry, and careful consideration is under-way of numerous options to deal effectively with the potential consequences. The earth's temperature has risen about 0.5 degrees Celsius during the past 100 years. It is not known, however, whether this warning is part of a natural cycle or whether man-made emissions will cause additional warning. Scientists speculate the earth's temperature would have to rise another four to five degrees Celsius for significant adverse effects to result from global warming. The utility industry plans to give careful consideration to an array of supply and demand options, he said. Reliable and affordable electric generation is imperative to our society and will be increasingly important in helping societies adapt if global warning does occur. The nation needs a balanced energy mix to ensure an adequate energy supply. The development of new clean coal burning technologies is essential and should be accelerated to increase efficiency and minimize atmospheric emissions. The utility industry is also looking at processes that will reduce CO{sub 2} emissions in the industrial and transportation sectors.

  19. "Cairo must address the equity issue." Interview: Sandra Postel.

    PubMed

    1994-01-01

    Sandra Postel, of the Worldwatch Institute, believes that inequalities in consumption and income foster environmental degradation. The richest 20% are getting richer and consuming excessively. The bottom 20%, comprising about 1 billion people, are getting poorer and are degrading their environment in order to survive. Per capita availability of resources is continually being reduced. If there is a desire to improve the quality of life for the poorest segment of the world population, then the richest must forfeit something. Environmental taxation could reduce excessive consumption in general; this strategy would be the most efficient and useful. Taxes would be placed on pollution and resources in danger of depletion; income taxes could be reduced to balance the impact of increased taxes on the economy. Wealthy countries must make a renewed commitment to poverty alleviation and to realistic sustainable development. Aid budgets should no longer reflect military priorities or strategic objectives. Trade is clearly related to the environment and poverty, and these connections must be made publicly known. National and international trade policies must deal with poverty issues and not contribute to further environmental destruction. Eliminating debt problems is another problem in need of change. The World Bank and structural adjustment policies have not proved to be environmentally sound and have not benefitted the poor. Evaluation of programs is needed, and lending policies should reflect the growing awareness of the problems of the poor and environmental consequences. Consumption of energy, wood, paper, and water are all higher among industrialized wealthy countries. Technology needs to be applied to maximize resource use, and policies must reflect this commitment. Israel has set a good example with water consumption reduction through advanced technology.

    2016-01-01

    IntroductionThis circular provides an overview of selected activities that were conducted within the U.S. Geological Survey (USGS) Integrated Methods Development Project, an interdisciplinary project designed to develop new tools and conduct innovative research requiring integration of geologic, geophysical, geochemical, and remote-sensing expertise. The project was supported by the USGS Mineral Resources Program, and its products and acquired capabilities have broad applications to missions throughout the USGS and beyond.In addressing challenges associated with understanding the location, quantity, and quality of mineral resources, and in investigating the potential environmental consequences of resource development, a number of field and laboratory capabilities and interpretative methodologies evolved from the project that have applications to traditional resource studies as well as to studies related to ecosystem health, human health, disaster and hazard assessment, and planetary science. New or improved tools and research findings developed within the project have been applied to other projects and activities. Specifically, geophysical equipment and techniques have been applied to a variety of traditional and nontraditional mineral- and energy-resource studies, military applications, environmental investigations, and applied research activities that involve climate change, mapping techniques, and monitoring capabilities. Diverse applied geochemistry activities provide a process-level understanding of the mobility, chemical speciation, and bioavailability of elements, particularly metals and metalloids, in a variety of environmental settings. Imaging spectroscopy capabilities maintained and developed within the project have been applied to traditional resource studies as well as to studies related to ecosystem health, human health, disaster assessment, and planetary science.

    The 49-year-old Chemistry and Metallurgy Research (CMR) Facility is where analytical chemistry and metallurgical studies on samples of plutonium and nuclear materials are conduct in support of the Department of Energy's nuclear weapons program. The CMR Facility is expected to be decontaminated and decommissioned (D and D) over the next ten to twenty years. Over the decades, several hazardous material issues have developed that need to be address. Unstable chemicals must be properly reassigned or disposed of from the workspace during D and D operation. Materials that have critical effects that are primarily chronic in nature, carcinogens, reproductive toxin, and materials that exhibit high chronic toxicity, have unique decontamination requirements, including the decontrolling of areas where these chemicals were used. Certain types of equipment and materials that contain mercury, asbestos, lead, and polychlorinated biphenyls have special provisions that must be addressed. Utilization of commercially available software programs for addressing hazardous material issues during D and D operations such as legacy chemicals and documentation are presented. These user-friendly programs eliminate part of the tediousness associated with the complex requirements of legacy hazardous materials. A key element of this approach is having a program that inventories and tracks all hazardous materials. Without an inventory of chemicals stored in a particular location, many important questions pertinent to D and D operations can be difficult to answer. On the other hand, a well-managed inventory system can address unstable and highly toxic chemicals and hazardous material records concerns before they become an issue. Tapping into the institutional database provides a way to take advantage of the combined expertise of the institution in managing a cost effective D and D program as well as adding a quality assurance element to the program.

    Hayter, S. J.

    1998-10-31

    The photovoltaic (PV) industry is rapidly beginning to recognize the market potential of the buildings sector. New PV-for-buildings products have recently become commercially available, and numerous products that are under development will be introduced within the next 5 years. To ensure that these new products will be adopted and used in common building practices, the PV industry should recognize and address important buildings industry issues. These issues include building codes and standards, after-market servicing, education, and warranties and insurance policies. Photovoltaic systems are also still very expensive. The simplest method for increasing their value for a building is to decrease the building's electrical loads through energy efficiency and conservation. Meeting these goals can only be accomplished through partnerships with the U.S. Department of Energy (DOE), private industry, and public institutions.

  4. Human Health Effects of Biphenyl: Key Findings and Scientific Issues

    Background: In support of the Integrated Risk Information System (IRIS), the U.S. Environmental Protection Agency (EPA) has evaluated the human health hazards of biphenyl exposure. Objectives: We review key findings and scientific issues regarding expected human health effects of biphenyl. Methods: Scientific literature from 1926 through September 2012 was critically evaluated to identify potential human health hazards associated with biphenyl exposure. Key issues related to the carcinogenicity and noncancer health hazards of biphenyl were examined based on evidence from experimental animal bioassays and mechanistic studies. Discussion: Systematic consideration of experimental animal studies of oral biphenyl exposure took into account the variety of study designs (e.g., study sizes, exposure levels, and exposure durations) to reconcile differing reported results. The available mechanistic and toxicokinetic evidence supports the hypothesis that male rat urinary bladder tumors arise through urinary bladder calculi formation but is insufficient to hypothesize a mode of action for liver tumors in female mice. Biphenyl and its metabolites may induce genetic damage, but a role for genotoxicity in biphenyl-induced carcinogenicity has not been established. Conclusions: The available health effects data for biphenyl provides suggestive evidence for carcinogenicity in humans, based on increased incidences of male rat urinary bladder tumors at high exposure levels and on female mouse liver tumors. Kidney toxicity is also a potential human health hazard of biphenyl exposure. Citation: Li Z, Hogan KA, Cai C, Rieth S. 2016. Human health effects of biphenyl: key findings and scientific issues.

    2016-01-01

    This Special Issue is devoted to the illustration and discussion of three key demographic variables (sex/gender, race/ethnicity, and socioeconomic status) that have been shown to moderate associations between psychophysiological processes and behavior. The introduction to the issue discusses the role of phenotypic plasticity in the emergence of different neural processes that achieve the same behavioral outcome, with emphasis on how these relatively stable developmental contexts affect brain/behavior associations without necessarily resulting in difference in behavior. These findings have profound significance for the implications of generalization and call into question the presumption that diverse samples produce an average result that is appropriately reflective of the individuals themselves. Increasing diversity within psychophysiological research is critical in elucidating mechanisms by which the human brain can accomplish cognitive and affective behaviors. This article further examines the logistical and ethical challenges faced in achieving this goal. PMID:26681612

    1991-01-01

    In the course of reassessing seismic hazards at the Idaho National Engineering Laboratory (INEL), several key issues have been raised concerning the effects of the earthquake source and site geology on potential strong ground motions that might be generated by a large earthquake. The design earthquake for the INEL is an approximate moment magnitude (M{sub w}) 7 event that may occur on the southern portion of the Lemhi fault, a Basin and Range normal fault that is located on the northwestern boundary of the eastern Snake River Plain and the INEL, within 10 to 27km of several major facilities. Because the locations of these facilities place them at close distances to a large earthquake and generally along strike of the causative fault, the effects of source rupture dynamics (e.g., directivity) could be critical in enhancing potential ground shaking at the INEL. An additional source issue that has been addressed is the value of stress drop to use in ground motions predictions. In terms of site geology, it has been questioned whether the interbedded volcanic stratigraphy beneath the ESRP and the INEL attenuates ground motions to a greater degree than a typical rock site in the western US. These three issues have been investigated employing a stochastic ground motion methodology which incorporates the Band-Limited-White-Noise source model for both a point source and finite fault, random vibration theory and an equivalent linear approach to model soil response.

    Clinton, R. G., Jr.; Levine, S. R.

    1998-01-01

    Ceramic matrix composites (CMC) offer significant advantages for future aerospace applications including turbine engine and liquid rocket engine components, thermal protection systems, and "hot structures". Key characteristics which establish ceramic matrix composites as attractive and often enabling choices are strength retention at high temperatures and reduced weight relative to currently used metallics. However, due to the immaturity of this class of materials which is further compounded by the lack of experience with CMC's in the aerospace industry, there are significant challenges involved in the development and implementation of ceramic matrix composites into aerospace systems. Some of the more critical challenges are attachment and load transfer methodologies; manufacturing techniques, particularly scale up to large and thick section components; operational environment resistance; damage tolerance; durability; repair techniques; reproducibility; database availability; and the lack of validated design and analysis tools. The presentation will examine the technical issues confronting the application of ceramic matrix composites to aerospace systems and identify the key material systems having potential for substantial payoff relative to the primary requirements of light weight and reduced cost for future systems. Current programs and future research opportunities will be described in the presentation which will focus on materials and processes issues.

    Objective The importance of pediatric research especially in the ethically proven trials resulted in considerable legislative attempts in association with compiling ethical guidelines. Because of children's vulnerability conducting pediatric research raises different ethical issues; the two most important of which are informed consent and risk-benefit assessment. Differences in religious and socio-cultural context limit implication of ethical standards. Methods At the aim of finding a solution we critically reviewed guidelines, and literatures as well as Islamic points in addition to comparing different viewpoints in application of ethical standards in pediatric research. Findings The literature review showed that pediatric research guidelines and authors’ viewpoints have the same basic ethical core, but there are some variations; depend on cultural, religious, and social differences. Furthermore, these standards have some limitations in defining informed consent according to child's age and capacity upon application. Conclusion In this regard Islamic approach and definition about growth development and puberty sheds light and clarifies a clearer and more rational address to the issue. PMID:23429172

    1993-10-01

    Water issues on forest lands involve many human elements and needs that are not addressed by advanced physical and biological research and technology. Major gaps in our knowledge of important patterns of climate, soils, and terrain can be filled by relatively basic data collection and monitoring programs. Careful analysis of existing data and field experience also can reveal appropriate directions for management. A focus on problem-solving can direct research more effectively towards the resolution of key issues. Despite their impact, resource policies have widely varying scientific foundations. Policy-makers need sound processes for policy development, including timely technical input that is clear, objective, and related to socio-economic considerations. Resource polices should be consistent and include not only regulation, but also research, education, assistance, and incentives. Knowledge and sound policies still may not produce the desired on-the-ground actions, however, because of variable awareness, understanding, skill, or supervision in the field. Education and training programs are important not only for resource technicians, but also for contractors, operators, and other forest workers. Good planning, communication, and field coordination further insure that problems are avoided and new opportunities for effective actions are identified.

    Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, has been described for more than a century and increasingly studied over the past several decades. This paper provides a focused review of issues pertaining to BDD that are relevant to DSM-V. The review presents a number of options and preliminary recommendations to be considered for DSM-V: 1) Criterion A may benefit from some rewording, without changing its focus or meaning; 2) Potential disadvantages of adding a new criterion to reflect BDD compulsive behaviors seem to outweigh potential advantages, but adding such a criterion remains an option that can be considered; 3) A clinical significance criterion seems necessary for BDD to differentiate it from normal appearance concerns; 4) BDD and eating disorders have some overlapping features and need to be differentiated; some minor changes to DSM-IV’s criterion C are suggested; 5) BDD should not be broadened to include body integrity identity disorder (apotemnophilia) or olfactory reference syndrome; 6) There is no compelling evidence for including diagnostic features or subtypes that are specific to gender-related, age-related, or cultural manifestations of BDD; 7) Adding muscle dysmorphia as a specifier may have clinical utility; and 8) The ICD-10 criteria for hypochondriacal disorder are not suitable for BDD, and there is no empirical evidence that BDD and hypochondriasis are the same disorder. The issue of how BDD’s delusional variant should be classified in DSM-V is briefly discussed and will be addressed more extensively in a separate paper. PMID:20533368

    1995-01-01

    Coverage of high-latitude areas in the northern hemisphere using geostationary satellites can not be achieved with good elevation angles, and highly inclined elliptical orbits (HEO) present one possible way to overcome this problem. The high elevation angles they achieve and the relative motion of the satellites across the sky, including satellite hand-over, present a specific set of requirements for the design of user terminals, be they for communication or broadcast-reception purposed. This paper reviews key design issues for user terminals operating with satellites in highly inclined elliptical orbits. While all aspects of user terminal design are broadly covered, special emphasis is given to the antenna and RF front-end design. The types of terminals discussed include communications terminals: the hand-held, the notebook, and the vehicle-mounted types, as well as the vehicle-mounted digital audio broadcasting (DAB) receiver terminal. A number of solutions are outlined, based on tradeoffs with respect to the most significant system interface parameters such as G/T and equivalent isotropically radiated power (EIRP). Candidate antenna and front-end configurations were studied, in particular patch and helical antennas with the principal aim of deriving low cost, yet effective solutions. Issues related to achieving best EIRP for the communications terminals are presented, taking into account radiation safety limits. The differences in the design of receive only versus receive/transmit RF front-ends for HEO system terminals are highlighted and solutions for both proposed. This paper summarizes the results of internal ESTEC studies and external ESA-sponsored work concerning major user terminal parameters and design aspects performed for Archimedes -- a HEO satellite constellation for multimedia broadcasting and communications.

    2008-01-01

    Electronic Personal Health Records (PHRs) has been perceived as the tool to empower consumers to become active decision-makers of their healthcare instead of leaving the decision to providers. However, there has been the lack of enthusiasm and adoption of PHRs. This paper examines the current healthcare climate and attempts to understand the major challenges associated with PHRs adoption. The paper-based and fragmented healthcare system is no longer appropriate for the digital economy of the 21st century. The integrated health information technology system is the solution to transform clinical practice to consumer centric and information driven. Tools such as PHRs are means to an end that provide better, safer and more affordable healthcare for consumers. However, there has been little research conducted to demonstrate PHR's tangible value, despite the widespread perceived value of these technologies. Although survey data reveals that there is a lack of awareness among the public, consumers are receptive to this concept, especially when a physician recommends it. Key issues in adopting PHRs and strategies for successful implementation of PHRs are discussed. PMID:18583296

    In this paper, I reflect on what can be learned by engaging in future thinking within our discipline, and what implications the results of that thinking may have for the development of nursing education. Recognizing the marvelous diversity of perspective within our discipline with regard to what will and ought to be our future mandate, it seems reasonable to search for some grounding in what might ensure that we enter that future wisely. We all know that change is a fundamental characteristic of all future projections, and yet that insight seems a weak justification for failure to plan. Nurse educators hold a particular obligation to ensure that they are preparing the professionals who will take that future forward. Although we have always recognized that they must nurse for today with an eye on tomorrow, it is inordinately difficult to come to some agreement on how we can best bridge that gap within our educational programs and strategies. Toward this end, I draw on lessons that can be drawn from our professional history as a rich and vibrant context to propose some key issues for that future theorizing. PMID:17028072

    Ultraviolet (UV) emissions radiated by hydroxyl (OH) is one of the fundamental elements in the prediction of radiation signature of high-altitude and high-speed vehicle. In this work, the OH A{sup 2}Σ{sup +}→X{sup 2}Π ultraviolet emission band behind the bow shock is computed under the experimental condition of the second bow-shock ultraviolet flight (BSUV-2). Four related key issues are discussed, namely, the source of hydrogen element in the high-altitude atmosphere, the formation mechanism of OH species, efficient computational algorithm of trace species in rarefied flows, and accurate calculation of OH emission spectra. Firstly, by analyzing the typical atmospheric model, the vertical distributions of the number densities of different species containing hydrogen element are given. According to the different dominating species containing hydrogen element, the atmosphere is divided into three zones, and the formation mechanism of OH species is analyzed in the different zones. The direct simulation Monte Carlo (DSMC) method and the Navier-Stokes equations are employed to compute the number densities of the different OH electronically and vibrationally excited states. Different to the previous work, the trace species separation (TSS) algorithm is applied twice in order to accurately calculate the densities of OH species and its excited states. Using a non-equilibrium radiation model, the OH ultraviolet emission spectra and intensity at different altitudes are computed, and good agreement is obtained with the flight measured data.

    This paper describes the results of an assessment of how well currently available Probabilistic Risk Assessment (PRA) data address a representative set of human risk issues of current concern to the US Nuclear Regulatory Commission (NRC). A three-step process was used to make that assessment. First, all Human Reliability Analysis (HRA) data included in 19 PRAs were identified, collected, and stored on a computer. Second, a list of human risk ''working level issues'' of concern to NRC was compiled. Finally, the HRA/PRA data which were collected from 19 PRAs were compared to the data needs to assess the extent to which currently available PRA data are useful in addressing human risk issues of concern to NRC. Less than 1% of the data needs were determined to be addressed by currently available PRA data. Findings indicate that PRA data could be far more useful in addressing human risk issues with modification of the development process and documentation structure of PRAs. In addition, information from non-PRA sources could be integrated with PRA data to address many other issues. 7 refs., 13 tabs.

    One of the greatest challenges in the fields of quantum information processing and quantum technologies is the detailed coherent control over each and every constituent of quantum systems with an ever increasing number of particles. Within this endeavor, harnessing of many-body entanglement against the detrimental effects of the environment is a major pressing issue. Besides being an important concept from a fundamental standpoint, entanglement has been recognized as a crucial resource for quantum speed-ups or performance enhancements over classical methods. Understanding and controlling many-body entanglement in open systems may have strong implications in quantum computing, quantum simulations of many-body systems, secure quantum communication or cryptography, quantum metrology, our understanding of the quantum-to-classical transition, and other important questions of quantum foundations.In this paper we present an overview of recent theoretical and experimental efforts to underpin the dynamics of entanglement under the influence of noise. Entanglement is thus taken as a dynamic quantity on its own, and we survey how it evolves due to the unavoidable interaction of the entangled system with its surroundings. We analyze several scenarios, corresponding to different families of states and environments, which render a very rich diversity of dynamical behaviors.In contrast to single-particle quantities, like populations and coherences, which typically vanish only asymptotically in time, entanglement may disappear at a finite time. In addition, important classes of entanglement display an exponential decay with the number of particles when subject to local noise, which poses yet another threat to the already-challenging scaling of quantum technologies. Other classes, however, turn out to be extremely robust against local noise. Theoretical results and recent experiments regarding the difference between local and global decoherence are summarized.

    Quantum key distribution (QKD) is a secure key generation method between two distant parties by wisely exploiting properties of quantum mechanics. In QKD, experimental measurement outcomes on quantum states are transformed by the two parties to a secret key. This transformation is composed of many logical steps (as guided by security proofs), which together will ultimately determine the length of the final secret key and its security. We detail the procedure for performing such classical postprocessing taking into account practical concerns (including the finite-size effect and authentication and encryption for classical communications). This procedure is directly applicable to realistic QKD experiments and thus serves as a recipe that specifies what postprocessing operations are needed and what the security level is for certain lengths of the keys. Our result is applicable to the BB84 protocol with a single or entangled photon source.

    Nghiem, Nhung; Genç, Murat; Blakely, Tony

    2013-01-01

    Pricing policies such as taxes and subsidies are important tools in preventing and controlling a range of threats to public health. This is particularly so in tobacco and alcohol control efforts and efforts to change dietary patterns and physical activity levels as a means of addressing increases in noncommunicable diseases. To understand the potential impact of pricing policies, it is critical to understand the nature of price elasticities for consumer products. For example, price elasticities are key parameters in models of any food tax or subsidy that aims to quantify health impacts and cost-effectiveness. We detail relevant terms and discuss key issues surrounding price elasticities to inform public health research and intervention studies. PMID:24028228

  14. Sulfur, a Key Water Quality Issue in the Everglades

    Sulfur is an important water quality issue in the Everglades because of its role in microbial sulfate reduction and the methylation of mercury. Methylmercury (MeHg), a neurotoxin that is bioaccumulated, has been found in high concentrations in freshwater fish from the Everglades, and poses a potential threat to fish-eating wildlife and to human health through fish consumption. Sulfur appears to play a key role in regulating both the magnitude and distribution of MeHg in the Everglades. Freshwater wetlands typically have low sulfur concentrations, but marshes in portions of the northern Everglades have average surface water sulfate concentrations of 60 mg/l, compared to 1 mg/l or less at background sites. Marsh areas with excess sulfate are concentrated near sites of canal discharge and along canal levees. The canal water that is discharged into the marshes appears to be the major source of excess sulfate entering the Everglades. This canal water drains the Everglades Agricultural Area (EAA) and has sulfate concentrations averaging over 70 mg/l and periodically approaching 200 mg/l. We used sulfate concentration data and the sulfur (d34S) isotopic composition of sulfate in marsh surface water, canal water, rainwater, and groundwater to trace the source of the excess sulfate entering the Everglades. Results show that canal water from the EAA is the major source of excess sulfate entering the Everglades. Furthermore, canal water with the highest sulfate concentrations had d34S values of +16 per mil, similar to the d34S signature of agricultural sulfur used as a soil amendment in the EAA. Rainwater has too little sulfate to account for the high sulfate concentrations observed in the canals and in large portions of the Everglades. Groundwater beneath the present day Everglades generally has either too low a sulfate concentration or a d34S signature that is inconsistent with that of surface water in the Everglades. The excess sulfate entering the Everglades from canal

    A survey of global health experts attending an invited meeting provided a means to map key issues perceived to be shaping emerging global public health agendas. Eighty-five participants proposed three major issues likely to have the most significant impact on the field of global health in the coming years. Six raters grouped the resultant items, with multi-dimensional scaling (MDS) analysis producing a composite two-dimensional map depicting the overall patterning of items. Thematic clusters were incorporated within four major domains: changing health and prevention needs (15% of items), globalisation and global health governance (33% of items), transforming health systems (30% of items) and innovations in science and technology (7% of items). The remaining 15% of items addressed forms of environmental change. The distribution of items across domains was not significantly influenced by the current professional role of participants, their current location in the 'global north' or 'global south' or their region of focus (although the latter approached threshold significance). The constraints on interpretation imposed by the biases influencing participation in the survey are noted. However, the exercise suggests the potential for coherently defining shared agendas for diverse stakeholders to address emerging priorities. The closer integration of environmental concerns with other global public issues is clearly warranted. PMID:22765282

  16. Addressing Key Questions in the Bioatmospheric Nitrogen Cycle Using Stable Isotope Techniques

    2006-12-01

    The application of stable isotope techniques enables determination of the fate of applied or deposited reactive N, quantification of biogeochemical process rates, differentiation between microbial sources of N emissions, and determination of impacts on microbial biodiversity. Here we will introduce the 15N, 18O and 13C techniques we have developed and present results from studies where they have been applied to address the following key questions in the bioatmospheric N cycle: What is the fate of atmospheric deposited N in a plant-soil system? What impact does this N addition have on rates of key biogeochemical processes in the rhizosphere? What are the effects on the soil microbial community structure? How much of this N is returned to the atmosphere as N2O or N2? Using 15N and 18O enrichment techniques we are able to quantify gross mineralization rates and microbial immobilization, plant uptake and leaching of deposited or applied N, gross nitrification rates, quantify N2O and N2 production from ammonia oxidation, nitrifier denitrification and denitrification and distinguish between these sources, and derive a system N balance. These stable isotope techniques are being combined with molecular techniques (analysis of gene expression, 13C stable isotope probing (SIP)) to relate the measured processes to the microbial populations responsible and to assess effects of reactive N on community structure. Here we will give a synthesis of results from N deposition studies in semi-natural ecosystems and from N addition studies in agricultural systems, the information from which can be used to drive policy through the formulation of appropriate management and mitigation strategies for reactive N.

  1. Phycoremediation: key issues for cost-effective nutrient removal processes.

    PubMed

    Olguín, Eugenia J

    2003-12-01

    Phycoremediation applied to the removal of nutrients from animal wastewater and other high organic content wastewater is a field with a great potential and demand considering that surface and underground water bodies in several regions of the world are suffering of eutrophication. However, the development of more efficient nutrient removal algal systems requires further research in key areas. Algae growth rate controls directly and indirectly the nitrogen and phosphorus removal efficiency. Thus, maximum algae productivity is required for effective nutrient removal and must be considered as a key area of research. Likewise, low harvesting costs are also required for a cost-effective nutrient removal system. The use of filamentous microalgae with a high autoflocculation capacity and the use of immobilized cells have been investigated in this respect. Another key area of research is the use of algae strains with special attributes such as tolerance to extreme temperature, chemical composition with predominance of high added value products, a quick sedimentation behavior, or a capacity for growing mixotrophically. Finally, to combine most of the achievements from key areas and to design integrated recycling systems (IRS) should be an ultimate and rewarding goal. PMID:14623045

    2006-01-01

    Trichloroethylene (TCE) is a common environmental contaminant at hazardous waste sites and in ambient and indoor air. Assessing the human health risks of TCE is challenging because of its inherently complex metabolism and toxicity and the widely varying perspectives on a number of critical scientific issues. Because of this complexity, the U.S. Environmental Protection Agency (EPA) drew upon scientific input and expertise from a wide range of groups and individuals in developing its 2001 draft health risk assessment of TCE. This scientific outreach, which was aimed at engaging a diversity of perspectives rather than developing consensus, culminated in 2000 with 16 state-of-the-science articles published together as an Environmental Health Perspectives supplement. Since that time, a substantial amount of new scientific research has been published that is relevant to assessing TCE health risks. Moreover, a number of difficult or controversial scientific issues remain unresolved and are the subject of a scientific consultation with the National Academy of Sciences coordinated by the White House Office of Science and Technology Policy and co-sponsored by a number of federal agencies, including the U.S. EPA. The articles included in this mini-monograph provide a scientific update on the most prominent of these issues: the pharmacokinetics of TCE and its metabolites, mode(s) of action and effects of TCE metabolites, the role of peroxisome proliferator–activated receptor in TCE toxicity, and TCE cancer epidemiology.

    Objectives The purpose of this study was to use a qualitative approach to better understand the importance and efficacy of addressing spiritual issues within an interdisciplinary bone marrow transplant clinic from the perspectives of patients and healthcare providers. Setting Participants were recruited from the bone marrow transplant clinic of a large urban outpatient cancer care centre in western Canada. Participants: Focus groups were conducted with patients (n=7) and healthcare providers (n=9) to explore the importance of addressing spiritual issues across the treatment trajectory and to identify factors associated with effectively addressing these needs. Results Data were analysed using the qualitative approach of latent content analysis. Addressing spiritual issues was understood by patients and healthcare providers, as a core, yet under addressed, component of comprehensive care. Both sets of participants felt that addressing basic spiritual issues was the responsibility of all members of the interdisciplinary team, while recognising the need for specialised and embedded support from a spiritual care professional. While healthcare providers felt that the impact of the illness and treatment had a negative effect on patients’ spiritual well-being, patients felt the opposite. Skills, challenges, key time points and clinical indicators associated with addressing spiritual issues were identified. Conclusions Despite a number of conceptual and clinical challenges associated with addressing spiritual issues patients and their healthcare providers emphasised the importance of an integrated approach whereby basic spiritual issues are addressed by members of the interdisciplinary team and by an embedded spiritual care professional, who in addition also provides specialised support. The identification of clinical issues associated with addressing spiritual needs provides healthcare providers with clinical guidance on how to better integrate this aspect of care into

  5. Some key issues in reconstructions of Proterozoic supercontinents

    2006-10-01

    Supercontinents containing most of the earth's continental crust are considered to have existed at least twice in Proterozoic time. The younger one, Rodinia, formed at ˜1.0 Ga by accretion and collision of fragments produced by breakup of the older supercontinent, Columbia, which was assembled by global-scale 2.0-1.8 Ga collisional events. Little consensus has been reached regarding configurations of these supercontinents because of some unresolved issues concerning continental fits. One of these issues concerns how Siberia was related to Laurentia. Previous reconstructions that consider the Aldan Shield of Siberia as a continuation of the Wyoming Province of Laurentia have been largely abandoned in favor of models connecting Siberia to northern Laurentia, but it remains controversial which part of Siberia is contiguous with northern Laurentia. Also at issue is the western Laurentia-Australia-East Antarctica connection. Most Rodinia reconstructions place Australia, together with East Antarctica, adjacent to either western Canada (the SWEAT hypothesis) or the western United States (the AUSWUS hypothesis). However, recent studies combining paleomagnetic and isotopic age data have called into question the validity of SWEAT, AUSWUS and other variants. Another issue is the position of North China in Rodinia/Columbia. Limited paleomagnetic data seem to be consistent with the Paleo-Mesoproterozoic North China-Siberia/Baltica connection, whereas geological data support the recently proposed Archean to Mesoproterozoic North China-India connection. Controversial issues have also been raised about the timing and history of the amalgamation and fragmentation of South America and West Africa. Both geological and paleomagnetic data suggest that South America (São Francisco and Amazonia Cratons) and West Africa (Congo and West African Cratons) coalesced into a single landmass along the 2.1-2.0 Ga Transamazonian/Eburnean orogens. However, whether they were divorced and then re

    Intimate partner violence (IPV) is defined as violence committed by a current or former boyfriend or girlfriend, spouse or ex-spouse. Each year, 1.3 to 5.3 million women in the United States experience IPV. The large number of individuals affected, the enormous healthcare costs, and the need for a multidisciplinary approach make IPV an important healthcare issue. The Violence Against Women Act (VAWA) addresses domestic violence, dating violence, sexual assault, and stalking. It emphasizes development of coordinated community care among law enforcement, prosecutors, victim services, and attorneys. VAWA was not reauthorized in 2012 because it lacked bipartisan support. VAWA 2013 contains much needed new provisions for Native Americans; lesbian, gay, bisexual, transgender, gay, and queer (LGBTQ) individuals; and victims of human trafficking but does not address the large amount of intimate partner violence in America's immigrant population. There are important remaining issues regarding intimate partner violence that need to be addressed by future legislation.

  9. Early electioneering highlights party differences on key issues of choice.

    1992-07-29

    The Clinton-Gore ticket is solidly pro-choice. Gore was an official co-sponsor of the Freedom of Choice Act, the democratic platform endorses the Act, and Clinton has pledged to sign the Act if he becomes president. He also has pledged to make abortion a service that will be available under a universal health care program. The Bush-Quayle ticket is solidly anti-choice. Bush, who as a member of Congress was pro-choice, claims that his position has evolved until he now wants to ban it in all cases except to save the life of the mother, rape, or incest. He also is strongly against any Federal funding for abortion, or even referral for abortion. Quayle maintains his anti-choice position even though he has admitted that he would support he own daughter's decision, even if she chose abortion. The Republican party is planning on having strong anti-choice language in its platform. The issue also promises to be the most controversial issue of their convention. Political analysts insist that abortion will not be a major issue in this years election; however, the right to abortion has never been so severely threatened. A pro-choice president could undo all the restrictions placed on abortion during the Reagan-Bush era. With the stroke of a pen, the new president could revoke the Title X gag rule and the Mexico City policy (the international gag rule), restore US contribution to the UN Population Fund, eliminate the ban on abortions in US military facilities overseas, lift the import pan on RU-486, and allow federal funding for fetal tissue research.

    The currency, relevancy and changing nature of science makes it a natural topic of focus for mass media outlets. Science teachers and students can capitalize on this wealth of scientific information to explore socio-scientific and sustainability issues; however, without a lens on how those media are created and how representations of science are constructed through media, the use of mass media in the science classroom may be risky. Limited research has explored how science teachers naturally use mass media to explore scientific issues in the classroom or how mass media is used to address potential overlaps between socio-scientific-issue based instruction and education for sustainability. This naturalistic study investigated the reported and actual classroom uses of mass media by secondary science teachers' to explore socio-scientific and sustainability issues as well as the extent to which their instructional approaches did or did not overlap with frameworks for SSI-based instruction, education for sustainability, and media literacy education. The results of this study suggest that secondary science teachers use mass media to explore socio-scientific and sustainability issues, but their use of frameworks aligned with SSI-based, education for sustainability, and media literacy education was limited. This paper provides suggestions for how we, as science educators and researchers, can advance a teaching and learning agenda for encouraging instruction that more fully utilizes the potential of mass media to explore socio-scientific issues in line with perspectives from education for sustainability.

    The future appears rich in missions that will extend the frontiers of knowledge, human presence in space, and opportunities for profitable commerce. Key to the success of these ventures is the availability of plentiful, cost effective electric power and assured, low cost access to space. While forecasts of space power needs are problematic, an assessment of future needs based on terrestrial experience has been made. These needs fall into three broad categories: survival, self sufficiency, and industrialization. The cost of delivering payloads to orbital locations from LEO to Mars has been determined and future launch cost reductions projected. From these factors, then, projections of the performance necessary for future solar and nuclear space power options has been made. These goals are largely dependent upon orbital location and energy storage needs. Finally the cost of present space power systems has been determined and projections made for future systems.

  14. Some key issues in isotopic anomalies - Astrophysical history and aggregation

    NASA Technical Reports Server (NTRS)

    Clayton, D. D.

    1982-01-01

    Astrophysical history, particularly that period extending from stellar nucleosynthesis events to the formation of meteorites, is discussed as the key element for the understanding of isotopic anomalies in meteorites. The bulk homogeneity of the interstellar medium is considered, and it is argued that, despite the presence of spatial inhomogeneities due to different nucleosynthesis rates in different parts of the galaxy and supernova ejecta, a cosmic chemical memory of nucleosynthesis patterns, rather than an inhomogeneous injection, is the source of isotopic anomalies. According to this view, volatility patterns and some isotopic patterns are mapped onto a grain-size spectrum, and the FUN systematics may be explained by interstellar sputtering. Furthermore, meteoritic He and Ne abundances are inferred to be presolar, and the ubiquitous titanium isotopic anomalies are explained by processes of chemical fixation and condensation in varying environments.

    Ansorge, Wolfgang R.

    2006-06-01

    Hundreds of mirror segment, thousands of high precision actuators, highly complex mechanical, hydraulic, electrical and other technology subsystems, and extremely sophisticated control systems: an ELT system consists of millions of individual parts and components each of them may fail and lead to a partial or complete system breakdown. Component and system reliability does not only influence the acquisition costs of a product, it also defines the necessary maintenance work and the required logistic support. Taking the long operational life time of an ELT into account, reliability and maintainability are some of the main contributors to the system life cycle costs. Reliability and maintainability are key characteristics of any product and have to be designed into it from the early beginning; they can neither be tested into a product nor introduced by numerous maintenance activities. This presentation explains the interconnections between Reliability, Availability, Maintainability and Safety (RAMS) and outlines the necessary RAMS and Reliability Centered Maintenance (RCM) processes and activities during the entire life cycle of an ELT and an ELT instrument from the initial planning to the eventual disposal phase.

  16. Key issues in constellation design optimization for NGSO satellite systems

    NASA Astrophysics Data System (ADS)

    Wang, Arthur W.

    1998-01-01

    This paper presents various constellation design criteria for satellite systems in non-geostationary orbits (NGSO). Key design parameters, constraints, and tradeoffs are discussed for two classes of orbits: circular and non-circular. Circular orbits, such as the low earth orbits (LEO), the medium earth orbits (MEO), and the highly inclined geosynchronous orbits (IGSO), have equal coverage period for both north and south hemispheres while non-circular orbits such as the various type of elliptical orbits provide more focused coverage period at certain specific geographic locations. Different services require various constraints including delay, power economics, coverage region, frequency sharing, total capacity, satellite and launch-vehicle numbers. Detailed discussion of the relationship between these constraints and constellations are provided. A comparison between a proposed benchmark MEO system with other proposed broadband NGSO satellite systems is presented to demonstrate the importance of constellation design to enhance frequency-sharing capability. A potential ``satellite highway'' accommodating families of elliptical geosynchronous satellites is also presented. This is a novel approach to regulatory NGSO constellations which will facilitate sharing valuable resources of spectrum and useful spatial areas.

  17. Energy for sustainable development: Key issues and challenges

    SciTech Connect

    2007-07-01

    Energy generation and use are strongly linked to all elements of sustainable development such as economic, social, and environmental. The history of human development rests on the availability and use of energy, the transformation from the early use of fire and animal power that improved lives, to the present world with use of electricity and clean fuels for a multitude of purposes. Energy is the neglected issue of the development debate. The lack of access to reliable and clean energy supplies is a major barrier to improving human well-being around the globe. There are an estimated 1.6 billion people living in the rural areas of developing countries who lack access to electricity, and so dependence on fossil fuels. Combustion of fossil fuels produces large amounts of CO{sub 2}, an important greenhouse gas. In response to increasing concern about the effect of anthropogenic greenhouse gases on global climate, international action has been agreed to reduce these emissions. On the other hand, renewable energy is the great, barely tapped solution to the two great challenges of the coming century such as poverty and global warming. Not only can renewable energy provide a clean, flexible power source for homes, schools and hospitals, at the micro-to-medium scale it has huge potential to create meaningful and useful jobs.

  18. Ecotoxicology for risk assessment in arid zones: some key issues.

    PubMed

    Everts, J W

    1997-01-01

    In the hot arid zones of the world, ecotoxicological research is in statu nascendi. In these zones, the major sources of contamination by toxicants are: (1) plant protection and vector control in wet zones; (2) large-scale crop protection campaigns in dry and ephemeral wet zones; (3) refuse and obsolete pesticides in dry zones; and (4) mining. Economic development in many of these zones requires an adequate knowledge of certain basic principles, i.e., where extrapolating existing knowledge does not apply. The vulnerability of ecosystems to contaminants is closely related to water flow. In dry areas, species are susceptible to factors that interfere with the ecophysiological properties regulating water loss. Most hot arid areas are found at low latitudes where temperatures show striking extremes both in time and space. Living organisms are physiologically resistant and/or show adaptive behavior to these temperature extremes. Very little is known about the effects of toxicants on these key resistant and adaptive functions, although by extrapolation a few assumptions can be made. The effects of hyperthermia, for instance, can be aggravated by GSH depleting substances, and the temporary disabling effects characteristic of many pesticides may prove fatal under these circumstances. Most wet areas show a spatial concentration of both human activity and wildlife. In mesic zones, the contamination of water represents a health risk to both humans and other living organisms. The vast majority of aquatic communities are those inhabiting temporary pools and streams. Their populations are characterized by short reproductive cycles and/or long dormant stages. Toxicants affecting growth in these areas have been shown to have a deleterious effect. In a synthesis of existing knowledge the most prominent gaps are identified and priorities for further research are made. PMID:9002429

    Older adults living in deprived areas are at risk of developing frailty and becoming care dependent. The aim of this qualitative study is to explore how community-dwelling, older adults living in deprived neighbourhoods address ageing issues. In-depth interviews were conducted with 20 participants who were community-dwelling (independently living), aged 65 years and older, not dependent on care, and living in a socioeconomically deprived urban neighbourhood in the northern part of the Netherlands. Data were analysed using the constant comparative method. Our findings emphasise the resourcefulness of these older adults when coping with apparent adversities. Simultaneously, the findings convey deficits concerning knowledge about ageing and health. Despite this, it appeared that these older adults possess an optimistic view of life, accept their situation, and are content with the capacities they still possess. Perspectives on how older adults address ageing issues are important for developing leads for nursing practice. Nurses will be challenged to recognise the coping strategies of older adults, particularly considering their deficits in health knowledge. The results of this study may serve as a basis for community nurses to manage care for older adults in deprived neighbourhoods. PMID:26252237

    There are important practical and ethical considerations for organizations in conducting their own, or commissioning external, evaluations and for both practitioners and evaluators, when assessing programs built on strongly held ideological or philosophical approaches. Assessing whether programs "work" has strong political, financial, and/or moral implications, particularly when expending public dollars, and may challenge objectivity about a particular program or approach. Using a case study of the evaluation of a school-based abstinence-until-marriage program, this article discusses the challenges, lessons learned, and ethical responsibilities regarding decisions about evaluation, specifically associated with ideologically driven programs. Organizations should consider various stakeholders and views associated with their program to help identify potential pitfalls in evaluation. Once identified, the program or agency needs to carefully consider its answers to two key questions: Do they want the answer and are they willing to modify the program? Having decided to evaluate, the choice of evaluator is critical to assuring that ethical principles are maintained and potential skepticism or criticism of findings can be addressed appropriately. The relationship between program and evaluator, including agreements about ownership and eventual publication and/or promotion of data, should be addressed at the outset. Programs and organizations should consider, at the outset, their ethical responsibility when findings are not expected or desired. Ultimately, agencies, organizations, and programs have an ethical responsibility to use their data to provide health promotion programs, whether ideologically founded or not, that appropriately and effectively address the problems they seek to solve.

    After the revelation of kinase targeting with orally available small molecules, the use of imatinib in chronic myelogenous leukemia and in gastrointestinal stromal tumor (GIST) has now become commonplace and just two of many examples of the use of kinase inhibitors in cancer. In this article, we discuss important practice points that may impact upon questions of therapy of primary and metastatic GIST, with the hope that the questions addressed in this rare solid tumor can serve as examples of what can be achieved with kinase-directed therapies in other cancers. We present cases that highlight some of the key issues in GIST management and afterward discuss both points of consensus and controversial issues in what is now recognized as one of the most common forms of sarcoma. Implications for Practice: The treatment of gastrointestinal stromal tumor (GIST) has become sophisticated with the availability of three approved agents in many countries and 15 years of experience with primary and metastatic disease. Important lessons from tyrosine-kinase inhibitors in GIST can be gleaned from this experience and will impact implementation of similar agents for other cancers. PMID:26070915

    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

    On October 9, 2008, federal, state and local policy makers, emergency managers, and medical and public health officials convened in Seattle, Washington, for a workshop on Addressing the Federal-State-Local Interface Issues During a Catastrophic Event Such as an Anthrax Attack. The day-long symposium was aimed at generating a dialogue about recovery and restoration through a discussion of the associated challenges that impact entire communities, including people, infrastructure, and critical systems. The Principal Federal Official (PFO) provided an overview of the role of the PFO in a catastrophic event. A high-level summary of an anthrax scenario was presented. The remainder of the day was focused on interactive discussions among federal, state and local emergency management experts in the areas of: • Decision-making, prioritization, and command and control • Public health/medical services • Community resiliency and continuity of government. Key topics and issues that resulted from discussions included: • Local representation in the Joint Field Office (JFO) • JFO transition to the Long-Term Recovery Office • Process for prioritization of needs • Process for regional coordination • Prioritization - process and federal/military intervention • Allocation of limited resources • Re-entry decision and consistency • Importance of maintaining a healthy hospital system • Need for a process to establish a consensus on when it is safe to re-enter. This needs to be across all jurisdictions including the military. • Insurance coverage for both private businesses and individuals • Interaction between the government and industry. The symposium was sponsored by the Interagency Biological Restoration Demonstration, a collaborative regional program jointly funded by the U.S. Department of Homeland Security and the U.S. Department of Defense.

    The ageing process is influenced by a variety of factors, including extrinsic, malleable lifestyle variables. The present paper deals with the epidemiological evidence for the role of dietary patterns and key nutritional concerns in relation to survival and ageing-related disorders that present themselves in later life. Healthful dietary patterns appear to be most relevant in old age. Specific nutritional concerns are related to vitamin D, vitamin B12 and protein malnutrition. An important challenge to further expand the knowledge base is currently addressed by the NuAge project, acknowledging the complexity of the ageing process and integrating different dimensions of research into human healthy ageing. In the meantime, reversing poor adherence to existing guidelines for a healthy diet remains a first challenge in public health nutritional practices. PMID:26915284

    This article addresses an emerging policy problem in the United States participation in the electoral process by citizens with dementia. At present, health care professionals, family caregivers, and long-term care staff lack adequate guidance to decide whether individuals with dementia should be precluded from or assisted in casting a ballot. Voting by persons with dementia raises a series of important questions about the autonomy of individuals with dementia, the integrity of the electoral process, and the prevention of fraud. Three subsidiary issues warrant special attention: development of a method to assess capacity to vote; identification of appropriate kinds of assistance to enable persons with cognitive impairment to vote; and formulation of uniform and workable policies for voting in long-term care settings. In some instances, extrapolation from existing policies and research permits reasonable recommendations to guide policy and practice. However, in other instances, additional research is necessary.

    More frequently society is demanding that earth- and environmental-resource issues be evaluated and addressed by interdisciplinary investigators from the scientific, engineering, planning, and regulatory communities. Often these investigators are required to interact with a larger community of public stakeholders. Also, these investigators, by necessity, develop databases and models derived from disparate data sets that are often large, complex, and vary dramatically in scale and quality. The tools to facilitate the interactions of these communities of individuals have only recently garnered the appropriate sophistication to enable real-time data viewing, encoding, browsing, and modeling. At the same time, the advent of second-generation internet, or Web 2.0, technologies found in web-based communities and hosted services (such as social-networking, wikis, weblogs, social bookmarking, podcasts, and RSS web feeds) have fused with the more traditional two- and three-dimensional geographic information systems. This "mash-up" of web-based and stand-alone tools and services creates a highly interactive user environment that is favorable to real-time collaboration, community discussion, and broad public dissemination in a wide-area distributed network. These tools and services are being utilized to facilitate the investigations and conversations of scientists and other stakeholders addressing water resource sustainability issues in the desert southwestern United States. The data and models derived from these investigations are visualized using industry standard tools like ArcGIS, Google Earth, and Google Maps to enable ease-of-use by both the technical and the public stakeholder communities.

    Youth problems including risky sex, drug use, violence and mental health issues are on the rise in Vietnam. Mindfulness is proposed as one way to address unskillful responses to stress that give rise to these behavioral and psychosocial issues in Vietnam. This study explores the feasibility of a mindfulness program for adolescents and young adults in a central city in Vietnam. The mindfulness-based intervention was comprised 1-h daily session over 3 weeks that was conducted at two different sites, one with handicapped adolescents/young adults at the Vocational School for Handicapped and the other with at-risk youth at a semi-private high school. Forty-two Vietnamese youth participants and five Vietnamese teachers/facilitators who were trained in the mindfulness program provided personal reflections of their experiences. Analyses of the qualitative data suggest that mindfulness was enthusiastically received and accepted by both youth and teachers. There is strong indication that mindfulness is promising as a prevention strategy to help with stress and to build important life skills among Vietnamese youth. PMID:25452422

    2012-06-01

    Current High Energy and Nuclear Physics (HENP) libraries and frameworks were written before multicore systems became widely deployed and used. From this environment, a 'single-thread' processing model naturally emerged but the implicit assumptions it encouraged are greatly impairing our abilities to scale in a multicore/manycore world. While parallel programming - still in an intensive phase of R&D despite the 30+ years of literature on the subject - is an obvious topic to consider, other issues (build scalability, code clarity, code deployment and ease of coding) are worth investigating when preparing for the manycore era. Moreover, if one wants to use another language than C++, a language better prepared and tailored for expressing concurrency, one also needs to ensure a good and easy reuse of already field-proven libraries. We present the work resulting from such investigations applied to the Go programming language. We first introduce the concurrent programming facilities Go is providing and how its module system addresses the build scalability and dependency hell issues. We then describe the process of leveraging the many (wo)man-years put into scientific Fortran/C/C++ libraries and making them available to the Go ecosystem. The ROOT data analysis framework, the C-BLAS library and the Herwig-6 MonteCarlo generator will be taken as examples. Finally, performances of the tools involved in a small analysis written in Go and using ROOT I/O library will be presented.

    Malawi women are in the ironic juxtaposition of being socially disempowered while, at the same time, thought to hold the key to shaping an effective community response to the HIV crisis. Based on this juxtaposition, a descriptive, qualitative study was conducted in Malawi and the United States where 26 participants from nongovernmental organizations (NGOs) and community-based organizations (CBOs) discussed the roles of Malawi women. Interviews were audiotaped, transcribed, and analyzed. We identified an improvement in women's economic status as the strongest factor in reducing gender inequities. Through providing stipends for rural Malawi women, one NGO created unintended changes in gender roles. PMID:23311905

    2005-04-25

    Defense Nuclear Facilities Safety Board (DNFSB) Recommendation 2002-1 (''Quality Assurance for Safety-Related Software'') identified a number of quality assurance issues on the use of software in Department of Energy (DOE) facilities for analyzing hazards, and designing and operating controls to prevent or mitigate potential accidents. Over the last year, DOE has begun several processes and programs as part of the Implementation Plan commitments, and in particular, has made significant progress in addressing several sets of issues particularly important in the application of software for performing hazard and accident analysis. The work discussed here demonstrates that through these actions, Software Quality Assurance (SQA) guidance and software tools are available that can be used to improve resulting safety analysis. Specifically, five of the primary actions corresponding to the commitments made in the Implementation Plan to Recommendation 2002-1 are identified and discussed in this paper. Included are the web-based DOE SQA Knowledge Portal and the Central Registry, guidance and gap analysis reports, electronic bulletin board and discussion forum, and a DOE safety software guide. These SQA products can benefit DOE safety contractors in the development of hazard and accident analysis by precluding inappropriate software applications and utilizing best practices when incorporating software results to safety basis documentation. The improvement actions discussed here mark a beginning to establishing stronger, standard-compliant programs, practices, and processes in SQA among safety software users, managers, and reviewers throughout the DOE Complex. Additional effort is needed, however, particularly in: (1) processes to add new software applications to the DOE Safety Software Toolbox; (2) improving the effectiveness of software issue communication; and (3) promoting a safety software quality assurance culture.

    Micronutrient deficiency conditions are a major global public health problem. While the private sector has an important role in addressing this problem, the main responsibility lies with national governments, in cooperation with international agencies and donors. Mandatory fortification of basic foods provides a basic necessary intake for the majority and needs to be supported by provision of essential vitamin and mineral supplements for mothers and children and other high risk groups. Fortification by government mandate and regulation is essential with cooperation by private sector food manufacturers, and in the context of broader policies for poverty reduction, education and agricultural reform. Iron, iodine, vitamin A, vitamin B complex, folic acid, zinc, vitamin D and vitamin B12 are prime examples of international fortification experience achieved by proactive governmental nutrition policies. These are essential to achieve the Millennium Development Goals and their follow-up sustainable global health targets. National governmental policies for nutritional security and initiatives are essential to implement both food fortification and targeted supplementation policies to reduce the huge burden of micronutrient deficiency conditions in Southeast Asia and other parts of the world.

    The world of healthcare professionals is in a constant state of transition, requiring different processes for the organization, and for completing projects and programs. Projects that manage transition are complex undertakings prone to cost and time overruns. An enterprise project management model is proposed to address the people, process and technology dimensions. It includes the five-step PMI project process, vocabulary, processes, soft skills, stakeholder expectation management, portfolio management and talent diversity. Differences in project deliverables and organizational results are discussed, along with a technique to analyze gaps from the current to the new state, which then defines the projects and programs for an organizational initiative. The role and responsibilities of an executive decision team are defined. Learning the model is needed by all members of the organization, regardless of their role or level, for successfully adapting to future changes. Finally, a case is made for healthcare organizations to implement these competencies if they are to be well-performing organizations in this continuous world of change. PMID:19195295

Focus areas cited in the report include: Strengthening the connections between two-year colleges and four-year institutions Sharing and making use of successful recruitment and retention practices for students from underrepresented groups Making students aware of high-quality job prospects in the geosciences as well as its societal relevance The InTeGrate STEP Center for the Geosciences, the Supporting and Advancing Geoscience Education at Two-Year Colleges (SAGE 2YC) program, and the Building Strong Geoscience Departments (BSGD) project together have developed a suite of web resources to help faculty and program leaders begin to address these and other issues. These resources address practices that support the whole student, both in the classroom and as a part of the co-curriculum as well as information on geoscience careers, guidance for developing coherent degree programs, practical advice for mentoring and advising, and many others. In addition to developing web resources, InTeGrate has also undertaken an effort to profile successful program practices at a variety of institutions. An analysis of these data shows several common themes (e.g. proactive marketing, community building, research experiences) that align well with the existing literature on what works to support student success. But there are also indications of different approaches and emphases between Minority Serving Institutions (MSIs) and Primarily White Institutions (PWIs) as well as between different kinds of MSIs. Highlighting the different strategies in use can point both MSIs and PWIs to possible alternate solutions to the challenges their students face. InTeGrate - http

    Globally, alum sludge is an easily, locally and largely available by-product from water treatment plants where aluminium sulphate is used as the coagulant for raw water purification. Owing to the high content of Al ions (29.7±13.3% dry weight) in alum sludge and the strong affinity of Al ions to adsorb various pollutants especially phosphorus (P), alum sludge (in the form of dewatered cakes) has been investigated in recent years as a low-cost alternative substrate in constructed wetland (CW) systems to enhance the treatment efficiency especially for high strength P-containing wastewater. Long-term trials in different scales have demonstrated that the alum sludge-based CW is a promising technique with a two-pronged feature of using 'waste' for wastewater treatment. Alum sludge cakes in CW can serve as a medium for wetland plant growth, as a carrier for biofilm development and as a porous material for wastewater infiltration. After the intensive studies of the alum sludge-based CW system, this paper aims to address the key issues and concerns pertaining to this kind of CW system. These include: (1) Is alum sludge suitable for reuse in CWs? (2) Is Al released from the sludge a concern? (3) What is the lifespan of the alum sludge in CWs? (4) How can P be recovered from the used alum sludge? (5) Does clogging happen in alum sludge-based CW systems and what is the solution? PMID:26067496

    The renewed emphasis on robotic and human missions within NASA's space exploration program warrants a detailed consideration of how the positions of objects in space will be determined and tracked, whether they be spacecraft, human explorers, robots, surface vehicles, or science instrumentation. The Navigation Team within the NASA Space Communications Architecture Working Group (SCAWG) has addressed several key technical issues in this area and the principle findings are reported here. For navigation in the vicinity of the Moon, a variety of satellite constellations have been investigated that provide global or regional surface position determination and timely services analogous to those offered by GPS at Earth. In the vicinity of Mars, there are options for satellite constellations not available at the Moon due to the gravitational perturbations from Earth, such as two satellites in an aerostationary orbit. Alternate methods of radiometric navigation as considered, including one- and two-way signals, as well as autonomous navigation. The use of a software radio capable of receiving all available signal sources, such as GPS, pseudolites, and communication channels, is discussed. Methods of time transfer and dissemination are also considered in this paper.

    The recent landmark report by the National Academy of Sciences reviewed the science on which the Kyoto Protocol was based. NAS concluded that the policy choices and the mandatory reductions in greenhouse gases by the developed nations were based on incomplete science with significant uncertainties. In view of these uncertainties the NAS report developed a comprehensive strategic 10-year research program to address the basic issue of whether human activity that results in environmental changes is responsible for climate changes. The report provides a new framework for consideration of global warming issues. The UN International Panel on Climate Change (the UN science advisor) in its 1997 report to the Kyoto parties pointed out the confusing difference between scientific usage of the term "climate change" that distinguishes human from natural causes of change and the official usage that combines natural and human causes of changes in climate. The conclusion of the UN panel on human causes is equivocal. The 1999 report of the U.S. Global Science Research Committee also reached an equivocal conclusion on human causes and announced a 10-year research program to be developed in consultation with NAS. The precautionary measures provided in the 1992 UN Framework Convention differ from the ill-defined "precautionary principle" based on fear of uncertainty, and are consistent with the objectives of the NAS proposed research program. These developments together with the third report of the UN Intergovernmental Science Panel on developments in climate science due in 2001 merit consideration by the convention of the parties under the Kyoto Protocol.

    DIII-D has made significant advances in the scientific basis for fusion energy. The physics mechanism of resonant magnetic perturbation (RMP) edge localized mode (ELM) suppression is revealed as field penetration at the pedestal top, and reduced coil set operation was demonstrated. Disruption runaway electrons were effectively quenched by shattered pellets; runaway dissipation is explained by pitch angle scattering. Modest thermal quench radiation asymmetries are well described NIMROD modelling. With good pedestal regulation and error field correction, low torque ITER baselines have been demonstrated and shown to be compatible with an ITER test blanket module simulator. However performance and long wavelength turbulence degrade as low rotation and electron heating are approached. The alternative QH mode scenario is shown to be compatible with high Greenwald density fraction, with an edge harmonic oscillation demonstrating good impurity flushing. Discharge optimization guided by the EPED model has discovered a new super H-mode with doubled pedestal height. Lithium injection also led to wider, higher pedestals. On the path to steady state, 1 MA has been sustained fully noninductively with βN = 4 and RMP ELM suppression, while a peaked current profile scenario provides attractive options for ITER and a βN = 5 future reactor. Energetic particle transport is found to exhibit a critical gradient behaviour. Scenarios are shown to be compatible with radiative and snowflake divertor techniques. Physics studies reveal that the transition to H mode is locked in by a rise in ion diamagnetic flows. Intrinsic rotation in the plasma edge is demonstrated to arise from kinetic losses. New 3D magnetic sensors validate linear ideal MHD, but identify issues in nonlinear simulations. Detachment, characterized in 2D with sub-eV resolution, reveals a radiation shortfall in simulations. Future facility development targets burning plasma physics with torque free electron heating, the

    A modular approach to model design and construction provides a flexible framework in which to focus the multidisciplinary research and operational efforts needed to facilitate the development, selection, and application of the most robust distributed modelling methods. A variety of modular approaches have been developed, but with little consideration for compatibility among systems and concepts. Several systems are proprietary, limiting any user interaction. The US Geological Survey modular modelling system (MMS) is a modular modelling framework that uses an open source software approach to enable all members of the scientific community to address collaboratively the many complex issues associated with the design, development, and application of distributed hydrological and environmental models. Implementation of a common modular concept is not a trivial task. However, it brings the resources of a larger community to bear on the problems of distributed modelling, provides a framework in which to compare alternative modelling approaches objectively, and provides a means of sharing the latest modelling advances. The concepts and components of the MMS are described and an example application of the MMS, in a decision-support system context, is presented to demonstrate current system capabilities.

    A modular approach to model design and construction provides a flexible framework in which to focus the multidisciplinary research and operational efforts needed to facilitate the development, selection, and application of the most robust distributed modelling methods. A variety of modular approaches have been developed, but with little consideration for compatibility among systems and concepts. Several systems are proprietary, limiting any user interaction.

  12. Rewarding altruism: addressing the issue of payments for volunteers in public health initiatives.

    PubMed

    South, Jane; Purcell, Martin E; Branney, Peter; Gamsu, Mark; White, Judy

    2014-03-01

    Lay involvement in public health programmes occurs through formalised lay health worker (LHW) and other volunteer roles. Whether such participation should be supported, or indeed rewarded, by payment is a critical question. With reference to policy in England, UK, this paper argues how framing citizen involvement in health only as time freely given does not account for the complexities of practice, nor intrinsic motivations. The paper reports results on payment drawn from a study of approaches to support lay people in public health roles, conducted in England, 2007-9. The first phase of the study comprised a scoping review of 224 publications, three public hearings and a register of projects. Findings revealed the diversity of approaches to payment, but also the contested nature of the topic. The second phase investigated programme support matters in five case studies of public health projects, which were selected primarily to reflect role types. All five projects involved volunteers, with two utilising forms of payment to support engagement. Interviews were conducted with a sample of project staff, LHWs (paid and unpaid), external partners and service users. Drawing on both lay and professional perspectives, the paper explores how payment relates to social context as well as various motivations for giving, receiving or declining financial support. The findings show that personal costs are not always absorbed, and that there is a potential conflict between financial support, whether sessional payment or expenses, and welfare benefits. In identifying some of the advantages and disadvantages of payment, the paper highlights the complexity of an issue often addressed only superficially. It concludes that, in order to support citizen involvement, fairness and value should be considered alongside pragmatic matters of programme management; however policy conflicts need to be resolved to ensure that employment and welfare rights are maintained.

  2. Using Next Generation Science Standards (NGSS) Practices to Address Scientific Misunderstandings Around Complex Environmental Issues

    NASA Astrophysics Data System (ADS)

    Turrin, M.; Kenna, T. C.

    2014-12-01

    The new NGSS provide an important opportunity for scientists to develop curriculum that links the practice of science to research-based data in order to improve understanding in areas of science that are both complex and confusing. Our curriculum focuses in particular on the fate and transport of anthropogenic radionuclides. Radioactivity, both naturally occurring and anthropogenic, is highly debated and largely misunderstood, and for large sections of the population is a source of scientific misunderstanding. Developed as part of the international GEOTRACES project which focuses on identifying ocean processes and quantifying fluxes that control the distributions of selected trace elements and isotopes in the ocean, and on establishing the sensitivity of these distributions to changing environmental conditions, the curriculum topic fits nicely into the applied focus of NGSS with both environmental and topical relevance. Our curriculum design focuses on small group discussion driven by questions, yet unlike more traditional curriculum pieces these are not questions posed to the students, rather they are questions posed by the students to facilitate their deeper understanding. Our curriculum design challenges the traditional question/answer memorization approach to instruction as we strive to develop an educational approach that supports the practice of science as well as the NGSS Cross Cutting Concepts and the Science & Engineering Practices. Our goal is for students to develop a methodology they can employ when faced with a complex scientific issue. Through background readings and team discussions they identify what type of information is important for them to know and where to find a reliable source for that information. Framing their discovery around key questions such as "What type of radioactive decay are we dealing with?", "What is the potential half-life of the isotope?", and "What are the pathways of transport of radioactivity?" allows students to evaluate a

  10. Some physics and system issues in the security analysis of quantum key distribution protocols

    NASA Astrophysics Data System (ADS)

    Yuen, Horace P.

    2014-10-01

    In this paper, we review a number of issues on the security of quantum key distribution (QKD) protocols that bear directly on the relevant physics or mathematical representation of the QKD cryptosystem. It is shown that the cryptosystem representation itself may miss out many possible attacks, which are not accounted for in the security analysis and proofs. Hence, the final security claims drawn from such analysis are not reliable, apart from foundational issues about the security criteria that are discussed elsewhere. The cases of continuous-variable QKD and multi-photon sources are elaborated upon.

  11. Importance of Broken Gauge Symmetry in Addressing Three, Key, Unanswered Questions Posed by Low Nuclear Reactions (LENR's)

    NASA Astrophysics Data System (ADS)

    Chubb, Scott

    2003-03-01

    Three, Key, Unanswered Questions posed by LENR's are: 1. How do we explain the lack of high energy particles (HEP's)? 2. Can we understand and prioritize the way coupling can occur between nuclear- and atomic- lengthscales, and 3. What are the roles of Surface-Like (SL), as opposed to Bulk-Like (BL), processes in triggering nuclear phenomena. One important source of confusion associated with each of these questions is the common perception that the quantum mechanical phases of different particles are not correlated with each other. When the momenta p of interacting particles is large, and reactions occur rapidly (between HEP's, for example), this is a valid assumption. But when the relative difference in p becomes vanishingly small, between one charge, and many others, as a result of implicit electromagnetic coupling, each charge can share a common phase, relative to the others, modulo 2nπ, where n is an integer, even when outside forces are introduced. The associated forms of broken gauge symmetry, distinguish BL from SL phenomena, at room temperature, also explain super- and normal- conductivity in solids, and can be used to address the Three, Key, Unanswered Questions posed by LENR's.

    Ghost surgery occurs when a physician assistant, a surgical assistant, an RN first assistant, a resident, or another surgeon assists on or performs an operative or other invasive procedure without the patient's knowledge, regardless of whether the surgeon who obtained the consent was scrubbed in or not. This practice denies patients important information, eliminates their ability to provide informed consent, and represents an ethical issue that nurses must deal with when working with peers and patients. The American Nurses Association developed the Code of Ethics for Nurses to help guide nursing practice, and the provisions within the code embody the ethical issues that should guide nurses' practice in advocating for patients.

    2001-09-01

    Decisions about HIV prevention and treatment programs are based on factors such as program costs and health benefits, social and ethical issues, and political considerations. AIDS policy models--that is, models that evaluate the monetary and non-monetary consequences of decisions about HIV/AIDS interventions--can play a role in helping policy makers make better decisions. This paper provides an overview of the key issues related to developing useful AIDS policy models. We highlight issues of importance for researchers in the field of AIDS policy modeling as well as for policy makers. These include geographic area, setting, target groups, interventions, affordability and effectiveness of interventions, type and time horizon of policy model, and type of economic analysis. This paper is not intended to be an exhaustive review of the AIDS policy modeling literature, although many papers from the literature are discussed as examples; rather, we aim to convey the composition, achievements, and challenges of AIDS policy modeling.

    This study examined weight-related issues affecting elementary school children to gain insight into how best to address these issues within a school-based intervention. The study population included 21 students, 12 school staff members, and 21 parents from a school that serves an ethnically-diverse population. Data were collected using focus groups and individual interviews and were analyzed using qualitative research methodology. Weight-related teasing and poor body image emerged as prominent issues affecting students. Results suggest that programs aimed at the prevention of weight-related disorders should go beyond issues of nutrition and physical activity and include strategies to reduce weight-related mistreatment and to improve students' body image.

    Policing is widely held to constitute a contentious issue in classrooms on both sides of the border on the island of Ireland, despite the fact that the ongoing peace process has led to a normalising of cross-border policing relationships. The Education for Reconciliation Project works with teachers and members of the two police services to produce teaching/learning modules on law and policing for use in Citizenship Education classrooms. This paper examines the commonly-held teacher perception of policing as a controversial issue and the reasons why these perceptions exist. It takes into consideration the opinion that it is time for schools to begin work on policing, and investigates the implications for practice.

    The issues raised by noncommunicable diseases (NCDs) during and after disasters are a challenge to equity within local communities, as well as between countries. Individuals with NCDs are particularly vulnerable in disasters and their aftermath given health systems are disrupted. Although welcome progress has been made in taking NCDs and equity into account in the UN General Assembly ratified agreement, the Sendai Framework for disaster risk reduction 2015-2030, there is need now for a clear plan of implementation.

    2014-11-01

    This article reports on the outcomes of an intervention in a Swedish school in which the author, a teacher-researcher, sought to develop students' (14-15 years old) ethical reasoning in science through the use of peer discussions about socio-scientific issues. Prior to the student discussions various prompts were used to highlight different aspects of the issues. In addition, students were given time to search for further information themselves. Analysis of students' written arguments, from the beginning of the intervention and afterwards, suggests that many students seem to be moving away from their use of everyday language towards using scientific concepts in their arguments. In addition, they moved from considering cloning and 'designer babies' solely in terms of the present to considering them in terms of the future. Furthermore, the students started to approach the issues in additional ways using not only consequentialism but also the approaches of virtue ethics, and rights and duties. Students' progression in ethical reasoning could be related to the characteristics of the interactions in peer discussions as students who critically and constructively argued with each other's ideas, and challenged each other's claims, made progress in more aspects of ethical reasoning than students merely using cumulative talk. As such, the work provides valuable indications for the importance of introducing peer discussions and debates about SSIs in connection to biotechnology into the teaching of science in schools.

  2. Approaches of the German food industry for addressing the issue of food losses.

    2016-02-01

    In the food industry the subject of food losses is of great importance due to economic balance and an efficient application of resources as well as the development of an efficient food chain system. This paper presents the explorative results of a quantitative survey of leading companies of the German food industry to evaluate the relevance and handling of this issue. The investigation reveals that the topic food losses have a high significance in the food industry which will probably increase in future. A sample breakdown by branches indicates that the issue has the highest relevance for companies in the confectionery industry. These companies as well as those in the meat and fish industry want to consider the subject prospectively more powerful in their companies. Across the food industry, there is no communication to consumers of the efforts concerning food losses. And companies in the confectionery industry and in the fruit and vegetable industry rather want to engage more powerful in this topic if consumers' interest increases. But in order to minimize food losses at all stages along the supply chain, communication and collaboration at all stages is essential, especially the communication to consumers. Thus, it has to be verified whether a suitable communication can lead to advantages in competition and become an important issue for companies to differentiate from competitors. PMID:26691601

    An intervention was conducted, aimed at providing residents in internal medicine with communication skills to address end-of-life issues with patients. Residents participated in two 1-hour educational sessions designed to teach a communication protocol, enhance listening skills, and to provide practice in effective communication in a safe, small-group format. An anonymous on-line survey assessed the effectiveness of the intervention. Twenty-five residents completed the intervention. There was a trend toward increased comfort level in addressing end-of-life issues among residents who completed the intervention, versus a comparison group. Residents who completed the intervention reported that using the words "death" and "dying" with patients and families was an important teaching point. PMID:23977790

    The production of human induced pluripotent stem cells (hiPSCs) has greatly expanded the realm of possible stem cell-based regenerative medicine therapies and has particularly exciting potential for autologous therapies. However, future therapies based on hiPSCs will first have to address not only similar regulatory issues as those facing human embryonic stem cells with the US FDA and international regulatory agencies, but also hiPSCs have raised unique concerns as well. While the first possible clinical use of hiPSCs remains down the road, as a field it would be wise for us to anticipate potential roadblocks and begin formulating solutions. In this article, I discuss the potential regulatory issues facing hiPSCs and propose some potential changes in the direction of the field in response. PMID:22830621

    This study examined the self-assessed religiosity and spirituality (R/S) of a representative sample of German physicians in private practice (n = 414) and how this related to their addressing R/S issues with patients. The majority of physicians (49.3 %)reported a Protestant denomination, with the remainder indicating mainly either Catholic(12.5 %) or none (31.9 %). A significant proportion perceived themselves as either religious(42.8 %) or spiritual (29.0 %). Women were more likely to rate themselves R/S than did men. Women (compared to men) were also somewhat more likely to attend religious services (7.4 vs. 2.1 % at least once a week) and participate in private religious activities(14.9 vs. 13.7 % at least daily), although these differences were not statistically significant.The majority of physicians (67.2 %) never/seldom addressed R/S issues with a typical patient. Physicians with higher self-perceived R/S and more frequent public and private religious activity were much more likely to address R/S issues with patients. Implications for patient care and future research are discussed. PMID:24077926

    E-waste, a relatively recent addition to the waste stream in the form of discarded electronic and electric equipment, is getting increasing attention from policy makers as the quantity being generated is rising rapidly. One of the most promising policy options to address this issue is to extend the producers responsibility for their products beyond the point of sale, until end-of-product-life. This paper briefly introduces the concept of extended producer responsibility (EPR) and its applicability in the area of the end-of-life management of electronic and electrical equipment (EEE). It then examines the decade-long experience of Switzerland in using EPR to manage its e-waste, elaborating on the experience of the Swiss system in overcoming specific issues, and finally wrapping up with a synopsis of the lessons for policy makers. We consider each issue as an enquiry of questions confronting a policy maker and the choices that may present themselves. The five issues discussed are: (i) the challenges in getting an EPR based system started; (ii) securing financing to ensure a self-sustaining and smooth functioning system; (iii) organising a logistics network for the take back and collection of the e-waste; (iv) ensuring compliance of the various actors involved; and finally (v) reducing the threat of monopolistic practices.

    To achieve performance demonstration, which is a legal requirement for the qualification of NDE processes applied on French nuclear power plants, the use of modeling tools is a valuable support, provided that the employed models have been previously validated. To achieve this, in particular for eddy current modeling, a validation methodology based on the use of specific benchmarks close to the actual industrial issue has to be defined. Nonetheless, considering the high variability in code origin and complexity, the feedback from experience on actual cases has shown that it was critical to define simpler generic and public benchmarks in order to perform a preliminary selection. A specific Working Group has been launched in the frame of COFREND, the French Association for NDE, resulting in the definition of several benchmark problems. This action is now ready for mutualization with similar international approaches.

    There is growing concern among the general public and the scientific community regarding the potential toxicity of genetically modified organisms (GMOs). The use of biotechnology to enhance pest resistance or nutritional value has raised a number of fundamental questions including the consequences of insertion of reporter genes, the spread of resistance genes to surrounding plants, and the use of suicide genes to prohibit reuse of seed from engineered plants. Of particular interest is the ability of proteins from GMOs to elicit potentially harmful immunologic responses, including allergic hypersensitivity. The lack of information of the potential toxicity of these products suggests a need to identify the critical issues and research needs regarding these materials and to develop testing strategies to examine the allergenicity of these compounds.

    The development of managed behavioral health care carve-out contracts covering a discrete subset of benefits available for use by persons with mental health and/or substance abuse disorders poses major challenges for public purchasers. This Issue Brief explores several key issues that arise when drafting such agreements. Many of the issues that arise in the drafting of carve-out agreements will require the public purchaser to resolve basic policy questions well before the drafting of requests for proposals or contracts can proceed. Analyses of public sector managed behavioral health care contracts by attorneys at the Center for Health Policy Research suggest that there are four essential areas that must be addressed if mental health and substance abuse services are carved-out (either by the purchaser or by a comprehensive managed health care entity): (1) what population is eligible for enrollment; (2) what services is the contractor expected to furnish; (3) what triggers a duty on the part of the mental health or substance abuse carve-out contractor to provide services; and (4) how are services furnished by the managed behavioral health care contractor integrated with or coordinated with services furnished by a beneficiary's primary health care provider, with pharmaceutical benefits, and with other services that may be available to a beneficiary through a fee-for-service or other mechanism. However a purchaser chooses to resolve these four issues, it is essential that parallel clarifying clauses are also built into the contracts of primary health care providers and other entities providing needed services for persons whose mental health and substance abuse service needs are covered by the carve-out. Underlying all of these issues is the fact that ambiguity, vagueness, or failure to define terms and responsibilities can create unexpected and unwelcome clinical and financial liabilities to purchasers.

    Systemic lupus erythematous (SLE) is a chronic multisystem disease with significant associated morbidity and mortality. A deeper understanding of the pathogenesis of SLE has led to the development of biologic agents, primarily targeting B cells and others inhibiting costimulatory molecules, type I interferons and cytokines such as interleukin-6. Several of these agents have been studied in clinical trials; some have shown promise while others have yielded disappointing results. Economic and regulatory issues continue to hamper the availability of such therapies for SLE patients. With increasing recognition that recurrent flares of disease activity lead to long-term damage accrual, one of the most important recent developments in patient management has been the concept of treat-to-target in SLE while minimizing patient exposure to excessive corticosteroid and other immunosuppressive therapy. This article reviews these key issues in SLE management, outlining recent developments and clinical implications for patients. PMID:26622325

    2012-01-01

    Background Emergency planning in the UK has grown considerably in recent years, galvanised by the threat of terrorism. However, deficiencies in NHS emergency planning were identified and the evidence-base that underpins it is questionable. Inconsistencies in terminologies and concepts also exist. Different models of emergency management exist internationally but the optimal system is unknown. This study examines the evidence-base and evidence requirements for emergency planning in the UK health context. Methods The study involved semi-structured interviews with key stakeholders and opinion leaders. Purposive sampling was used to obtain a breadth of views from various agencies involved in emergency planning and response. Interviews were then analysed using a grounded approach using standard framework analysis techniques. Results We conducted 17 key informant interviews. Interviewees identified greater gaps in operational than technical aspects of emergency planning. Social and behavioural knowledge gaps were highlighted with regards to how individuals and organisations deal with risk and behave in emergencies. Evidence-based approaches to public engagement and for developing community resilience to disasters are lacking. Other gaps included how knowledge was developed and used. Conflicting views with regards to the optimal configuration and operation of the emergency management system were voiced. Conclusions Four thematic categories for future research emerged: (i) Knowledge-base for emergency management: Further exploration is needed of how knowledge is acquired, valued, disseminated, adopted and retained. (ii) Social and behavioural issues: Greater understanding of how individuals approach risk and behave in emergencies is required. (iii) Organisational issues in emergencies: Several conflicting organisational issues were identified; value of planning versus plans, flexible versus standardized procedures, top-down versus bottom-up engagement, generic versus

    2013-01-01

    Traditionally, biomedical research endeavors in low to middle resources countries have focused on communicable diseases. However, data collected over the past 20 years by the World Health Organization (WHO) show a significant increase in the number of people suffering from non-communicable diseases (e.g. heart disease, diabetes, cancer and pulmonary diseases). Within the coming years, WHO predicts significant decreases in communicable diseases while non-communicable diseases are expected to double in low and middle income countries in sub-Saharan Africa. The predicted increase in the non-communicable diseases population could be economically burdensome for the basic healthcare infrastructure of countries that lack resources to address this emerging disease burden. Biomedical research could stimulate development of healthcare and biomedical infrastructure. If this development is sustainable, it provides an opportunity to alleviate the burden of both communicable and non-communicable diseases through diagnosis, prevention and treatment. In this paper, we discuss how research using biomedical technology, especially genomics, has produced data that enhances the understanding and treatment of both communicable and non-communicable diseases in sub-Saharan Africa. We further discuss how scientific development can provide opportunities to pursue research areas responsive to the African populations. We limit our discussion to biomedical research in the areas of genomics due to its substantial impact on the scientific community in recent years however, we also recognize that targeted investments in other scientific disciplines could also foster further development in African countries.

    The unique or enhanced properties of manufactured nanomaterials (MNs) suggest that their use in nanoenabled products will continue to increase. This will result in increased potential for human and environmental exposure to MNs during manufacturing, use, and disposal of nanoenabled products. Scientifically based risk assessment for MNs necessitates the development of reproducible, standardized hazard testing methods such as those provided by the Organisation of Economic Cooperation and Development (OECD). Currently, there is no comprehensive guidance on how best to address testing issues specific to MN particulate, fibrous, or colloidal properties. This paper summarizes the findings from an expert workshop convened to develop a guidance document that addresses the difficulties encountered when testing MNs using OECD aquatic and sediment test guidelines. Critical components were identified by workshop participants that require specific guidance for MN testing: preparation of dispersions, dose metrics, the importance and challenges associated with maintaining and monitoring exposure levels, and the need for reliable methods to quantify MNs in complex media. To facilitate a scientific advance in the consistency of nanoecotoxicology test results, we identify and discuss critical considerations where expert consensus recommendations were and were not achieved and provide specific research recommendations to resolve issues for which consensus was not reached. This process will enable the development of prescriptive testing guidance for MNs. Critically, we highlight the need to quantify and properly interpret and express exposure during the bioassays used to determine hazard values. PMID:26182079

    This study examined the impact of Geese Theatre's Re-Connect program on a sample of offenders who attended it. This program used theatre performance, experiential exercises, skills practice role-plays, and metaphors such as the masks to invite a group of offenders to consider and explore issues connected with their release and reconnecting with a life outside prison. Pre- and postprogram psychometric tests, behavior ratings, and interviews were completed to assess the effectiveness of the program. Significant changes were observed from pre- to posttreatment in terms of self-efficacy, motivation to change, and improved confidence in skills (i.e., social and friendship, occupational, family and intimacy, dealing with authority, alternatives to aggression or offending, and self-management and self-control skills). Improved behavior and engagement within the program was observed over the 3 days of the program. Interviews also revealed the positive impact the program had on the participants. This provides evidence supporting the short-term effectiveness of the Re-Connect program. PMID:20472705

    The health sector challenges in India like those in other low and middle income countries are formidable. India has almost one-third of the world's dental schools. However, provisions of oral health-care services are few in rural parts of India where the majority of the Indian population resides. Disparities exist between the oral health status in urban and rural areas. The present unequal system of mainly private practice directed towards a minority of the population and based on reparative services needs to be modified. National oral health policy needs to be implemented as a priority, with an emphasis on strengthening dental care services under public health facilities. A fast-changing demographic profile and its implications needs to be considered while planning for the future oral health-care workforce. Current oral health status in developing countries, including India, is a result of government public health policies, not lack of dentists. The aim of the article is to discuss pertinent issues relating to oral health disparities, equity in health-care access, dental workforce planning and quality concerns pertaining to the present-day dental education and practices in India, which have implications for other developing countries.

    NREL builds community and industry support by addressing concerns voiced by key standards organizations. Photovoltaic (PV) manufacturers in the United States test the safety of their products using standards developed through consensus processes. Because U.S. PV module safety standards are not aligned with international standards, manufacturers must test their modules twice - and sometimes maintain separate product lines. By meeting with standards organizations such as the Solar ABCs and Underwriters Laboratories (UL), National Renewable Energy Laboratory (NREL) leaders have worked to identify different stakeholders priorities and concerns. UL, specifically, has expressed concern that the international standards do not address all possible risks. For example, new encapsulant materials could soften at high temperatures and frameless modules could slide apart, exposing live electrical parts or allowing glass to fall on a person below. The deformation of a solid material under the influence of mechanical stresses is known as 'creep.' Current module qualification tests are limited to 85 C, whereas modules can, for short times, reach 105 C outdoors. In response to UL's concern, NREL designed and executed an experiment to compare on-sun and accelerated rates of creep for modules fabricated with various encapsulants, including some that have low melting points. Objectives were to (1) evaluate the potential for creep in outdoor exposure, (2) provide guidance on the risks and design needs with thermoplastic materials, and (3) provide a basis for modifying standards to account for materials with potential to creep. The study tested experimental materials with eight representative encapsulants in both outdoor and indoor (chamber) exposure. The study found that modules with materials that were expected to creep did so in the indoor exposure, but not in most outdoor environments and mounting configurations. The results provide a basis for defining an accelerated test needed to

    As consumers and society in general become more aware of ethical and moral dilemmas associated with intensive rearing systems, pressure is put on the animal and poultry industries to adopt alternative forms of housing. This presents challenges especially regarding managing competitive social interactions between animals. However, selective breeding programs are rapidly advancing, enhanced by both genomics and new quantitative genetic theory that offer potential solutions by improving adaptation of the bird to existing and proposed production environments. The outcomes of adaptation could lead to improvement of animal welfare by increasing fitness of the animal for the given environments, which might lead to increased contentment and decreased distress of birds in those systems. Genomic selection, based on dense genetic markers, will allow for more rapid improvement of traits that are expensive or difficult to measure, or have a low heritability, such as pecking, cannibalism, robustness, mortality, leg score, bone strength, disease resistance, and thus has the potential to address many poultry welfare concerns. Recently selection programs to include social effects, known as associative or indirect genetic effects (IGEs), have received much attention. Group, kin, multi-level, and multi-trait selection including IGEs have all been shown to be highly effective in reducing mortality while increasing productivity of poultry layers and reduce or eliminate the need for beak trimming. Multi-level selection was shown to increases robustness as indicated by the greater ability of birds to cope with stressors. Kin selection has been shown to be easy to implement and improve both productivity and animal well-being. Management practices and rearing conditions employed for domestic animal production will continue to change based on ethical and scientific results. However, the animal breeding tools necessary to provide an animal that is best adapted to these changing conditions

    2013-05-01

    With the increasing concerns regarding both natural and induced seismicity in Ohio, ODNR (Ohio Department of Natural Resources) initial efforts on seismic risk reduction paved way to various changes and improvement to tackle several major issues. For natural earthquakes, regional seismicity indicates a NE-SW structure in the northern portion of the area associated with a number of moderate historical earthquakes but no active trace identified. On the other hand, earthquakes of 1986 and 2011 are most probably incidents of induced seismicity that trigger more public uproar against disposal of regulated waste waters through injections. ODNR, in efforts to adapt with increasing need to regulate all operations related to both the Utica and Marcellus shale play within the state, had recently strengthen itself both through additional human resources and improved infrastructure. Tougher regulations and additional field tests were required that took effect immediately when a M4 earthquake was associated with the operations of an injection well. Public meetings were undertaken focused on educating many local inhabitants related to oil and gas operations, hydraulic fracturing, injection wells, and seismicity. Trainings for new and existing staff were regularly done especially for field inspection, data management and technology advancements. Considering the existing seismic stations that are few and distant related to sites of the injection wells, additional seismic stations were installed to gather baseline data and monitor for earthquakes within the injection area(s). Furthermore, to assess if the sites of the injection wells are safe from active structures, initial geomorphic and structural analyses indicated possible active faults in the northern portion of state oriented NE-SW. With the above-mentioned recent changes, ODNR had made a significant leap not only in the improvement of its principal regulatory role in the state for oil and gas operations but also in its

    Being an Oncologist, I have seen many patients suffering from cancer. It pains a lot looking at them fighting the battle of life, though knowing that they would lose miserably and surrender meekly as majority of the patients report to the hospital at an advanced stage of disease and only palliative care may be the option. There is an urgent need to create - Cancer Awareness in the villages and also about the end of life care in all terminally ill patients. 20 patients in the terminal phase were questioned regarding end of life care. The common questions they asked are, why has God punished me like this? Why me on earth? Should I die so early? Why should I leave my near and dear ones and go far away, from the point of no return? Do I ever see them again? With deep sorrow and sigh, they suffer till the last breath, having the feeling of insecurity as what would happen to their dear ones. In the terminal phase, the patients wishes must be respected and their needs must be fulfilled. The health care professionals should plan an appropriate care for each patient. Most of them feel that the best place to be in end of life is the home. Research has shown that Hospice care may improve the quality of life of a patient who is dying and of the patient's family. Communication about end of life care and decision making during the final moments of a person's life are very important. The patients suffering are mainly due to the physical, psychological, social and spiritual issues. Death of a terminally ill patient should never be a sudden loss. All healthcare professionals, Social workers and Non-Governmental Organisations must install the life after death of the person, who has struggled for every breath and assure that he/she shall rest in peace and shall smile seeing their near and dear ones living with dignity and pride in the society. Ultimately, the patient must have dignity in dying. PMID:23440306

One of the most important issues relating to science education is the under-representation of African Americans and Hispanics in the science, technology, and engineering workforce. Foreshadowing such under-representation in the workforce are the disproportionately low rates of African American and Hispanic students attaining college degrees in science and related fields. Evidence suggests disparate systemic factors in secondary science education are contributing to disproportionately low numbers of African American and Hispanic students in the science education pipeline. The present paper embarks on a critical analysis of the issue by elucidating some of the systemic factors within secondary education that contribute to the leak in the science education pipeline. In addition, this review offers a synthesis and explication of some of the policies and programs being implemented to address disparate systemic factors in secondary schools. Finally, recommendations are offered regarding potential mechanisms by which disparities may be alleviated.

    Five popular, but distinctly different, remedial reading programs were reviewed regarding the potential to motivate children to read. It is argued that current remedial reading program designs and research on program effectiveness ignore the impact that motivation has on struggling readers. In addition, we develop a theory of reading motivation specific to struggling readers that highlights motivational constructs we feel are important to the improvement of reading skill for this population of students. The three aspects of reading motivation most relevant to the instruction of remedial readers include: (a) improving reading self-efficacy; (b) making internal and controllable outcome attributions for successes and failures associated with reading; and (c) establishing personally relevant value in becoming a better reader. We conclude that, while most programs address some motivational issues and other issues not at all, most programs could make minor modifications that would greatly enhance their motivational impact.

    Used to study the material and energy flow in socioeconomic system, Input-Output Analysis(IOA) had been an effective analysis tool since its appearance. The research fields of Input-Output Analysis were increasingly expanded and studied in depth with the development of fundamental theory. In this paper, starting with introduction of theory development, the water resources input-output analysis and environmental input-output analysis had been specifically reviewed, and two key study issues mentioned as well. Input-Occupancy-Output Analysis and Grey Input-Output Analysis whose proposal and development were introduced firstly could be regard as the effective complements of traditional IOA theory. Because of the hypotheses of homogeneity, stability and proportionality, Input-Occupancy-Output Analysis and Grey Input-Output Analysis always had been restricted in practical application inevitably. In the applied study aspect, with investigation of abundant literatures, research of water resources input-output analysis and environmental input-output analysis had been comprehensively reviewed and analyzed. The regional water resources flow between different economic sectors had been systematically analyzed and stated, and several types of environmental input-output analysis models combined with other effective analysis tools concluded. In two perspectives in terms of external and inland aspect, the development of water resources and environmental input-output analysis model had been explained, and several typical study cases in recent years listed respectively. By the aid of sufficient literature analysis, the internal development tendency and study hotspot had also been summarized. In recent years, Chinese literatures reporting water resources consumption analysis and virtue water study had occupied a large share. Water resources consumption analysis had always been the emphasis of inland water resources IOA. Virtue water study had been considered as the new hotspot of

    The increasing number of geospatial datasets and free online geo-ICT tools offers new opportunities for education in Earth Sciences. Geospatial technology indeed provides an environment through which interactive learning can be introduced in Earth Sciences curricula. However, the effectiveness of such e-learning approaches in terms of learning outcomes has rarely been addressed. Here, we present our experience with the implementation of digital interactive learning activities within an introductory Physical Geography course attended by 90 undergraduate students in Geography, Geology, Biology and Archaeology. Two traditional lectures were replaced by interactive sessions (each 2 h) in a flexible classroom where students had to work both in team and individually in order to explore some key concepts through the integrated use of geospatial data within Google EarthTM. A first interactive lesson dealt with the classification of river systems and aimed to examine the conditions under which rivers tend to meander or to develop a braided pattern. Students were required to collect properties of rivers (river channel pattern, channel slope, climate, discharge, lithology, vegetation, etc). All these data are available on a global scale and have been added as separate map layers in Google EarthTM. Each student collected data for at least two rivers and added this information to a Google Drive Spreadsheet accessible to the entire group. This resulted in a database of more than one hundred rivers spread over various environments worldwide. In a second phase small groups of students discussed the potential relationships between river channel pattern and its controlling factors. Afterwards, the findings of each discussion group were presented to the entire audience. The same set-up was followed in a second interactive session to explore spatial variations in ecosystem properties such as net primary production and soil carbon content. The qualitative evaluation of both interactive

    The evolution of Pilot-Vehicle-Interface (PVI) of a fighter aircraft is a complex task. The PVI design involves both static and dynamic issues. Static issues involve the study of reach of controls and switches, ejection path clearance, readability of indicators and display symbols, etc. Dynamic issues involve the study of the effect of aircraft motion on display symbols, pilot emergency handling, situation awareness, weapon aiming, etc. This paper describes a method of addressing the above issues by building a facility with cockpit, which is ergonomically similar to the fighter cockpit. The cockpit is also fitted with actual displays, controls and switches. The cockpit is interfaced with various simulation models of aircraft and outside-window-image generators. The architecture of the facility is designed to represent the latencies of the aircraft and facilitates replacement of simulation models with actual units. A parameter injection facility could be used to induce faults in a comprehensive manner. Pilots could use the facility right from familiarising themselves with procedures to start the engine, take-off, navigate, aim the weapons, handling of emergencies and landing. This approach is being followed and further being enhanced on Cockpit-Environment-Facility (CEF) at Aeronautical Development Agency (ADA), Bangalore, India.

    Fertility preservation in the young cancer survivor is recognized as a key survivorship issue by the American Society of Clinical Oncology and the American Society of Reproductive Medicine. Thus, health-care providers should inform women about the effects of cancer therapy on fertility and should discuss the different fertility preservation options available. It is also recommended to refer women expeditiously to a fertility specialist in order to improve counseling. Women’s age, diagnosis, presence of male partner, time available, and preferences regarding use of donor sperm influence the selection of the appropriate fertility preservation option. Embryo and oocyte cryopreservation are the standard techniques used while ovarian tissue cryopreservation is new, yet promising. Despite the importance of fertility preservation for cancer survivors’ quality of life, there are still communication and financial barriers faced by women who wish to pursue fertility preservation.

    This paper explores and discusses key issues for nurses and carers in implementing the evidence from the recent assessment of wandering studies conducted by Algase. Wandering is one of the most burdensome of all the behavioural symptoms and is increasing as the prevalence rates of dementia rise with the aging of the population. Wandering describes a diverse pattern of behaviour from aimless walking and pacing through to elopement. Until recently, the empirical evidence in relation to wandering and its implications for caring for older people has seriously lagged behind other research. However, several studies have led to important advances in the management of wandering and despite there being in some instances methodological deficiencies and modest efficacy, nurses, carers and older people who wander will benefit from the findings.

    2010-07-01

    Progressive depletion of conventional fossil fuels with increasing energy consumption and greenhouse gas (GHG) emissions have led to a move towards renewable and sustainable energy sources. Lignocellulosic biomass is available in massive quantities and provides enormous potential for bioethanol production. However, to ascertain optimal biofuel strategies, it is necessary to take into account environmental impacts from cradle to grave. Life cycle assessment (LCA) techniques allow detailed analysis of material and energy fluxes on regional and global scales. This includes indirect inputs to the production process and associated wastes and emissions, and the downstream fate of products in the future. At the same time if not used properly, LCA can lead to incorrect and inappropriate actions on the part of industry and/or policy makers. This paper aims to list key issues for quantifying the use of resources and releases to the environment associated with the entire life cycle of lignocellulosic bioethanol production. PMID:20015644

    1994-10-01

    Non-invasive inspection systems based on the use of fast neutrons are being studied for the inspection of large cargo containers. A key advantage of fast neutrons is their sensitivity to low-Z elements such as carbon, nitrogen, and oxygen, which are the primary constituents of explosives and narcotics. The high energy allows penetration of relatively large containers. The pulsed fast-neutron analysis (PFNA) technique is currently the baseline system. A workshop on the PFNA technique involving industrial, government, and university participants was held at Argonne National Laboratory in January 1994. The purpose of this workshop was to review the status of research on the key technical issues involved in PFNA, and to develop a list of those areas where additional modeling and/or experimentation were needed. The workshop also focused on development of a near-term experimental assessment program using existing prototypes and on development of a long-term test program at the Tacoma Testbed, where a PFNA prototype will be installed in 1995. A summary of conclusions reached at this workshop is presented. Results from analytic and Monte Carlo modeling of simplified PFNA systems are also presented.

    2012-01-01

    These days family-friendliness is a key issue for the future of businesses. Investments in a family conscious personnel policy are considered as forward-looking decisions in companies. This happens against the background of a sustainable personnel policy in times of a decrease in the number of employable persons, an increasing shortage of skilled workers and an ageing workforce. Family-friendly working conditions are becoming a key factor in the competition for staff. When choosing an employer, family-friendliness has become a crucial topic. Employment participation and skills of women, especially of mothers, have greatly increased. To facilitate the realisation of their wish to return to paid employment, however, measures to reconcile work and family are required. Family-conscious measures have been proven to lead to higher employee productivity. Job satisfaction and motivation of employees and accumulation of human capital increase, absenteeism declines, the return of investment rises. Fields of activity for family-friendly measures in companies range from working arrangements, parental leave and re-entry programmes and various child care offers to services for families. In connection with the demographic development the demand for a better reconciliation of work and elder care should in future become ever more important, just as the upkeep of the occupational skills and working capacity of an ageing workforce. Family-friendliness has to become an integral part of corporate culture. PMID:22558031

    Drug discovery is hard, and is becoming progressively harder, with the passage of time! No other field has to handle such an interplay of scientific, fiscal and political factors. The rewards are, nonetheless, worth it: people now live healthier and longer lives than at any point of time in the past. Times are, however, hard for pharmaceutical companies: research and development (R&D) costs are spiralling out of control. New drug approvals, on the other hand, have hit a record low; and the situation is expected to worsen, now that the FDA seems to be exhibiting stricter drug approval standards. Other issues also exacerbate circumstances: huge numbers of blockbuster medicines, which drugmakers rely on to generate their incomes, are coming off patent, and generic competition is intensifying. Both public and investor confidence in the industry have fallen drastically owing to rising drug prices, product safety concerns and late-stage clinical trial failures. This article discusses the key issues that pharmaceutical companies face and in particular the implications they have for the R&D process. I finish by suggesting how drugmakers should change their R&D strategies to succeed. PMID:23480332

  19. Using Eight Key Questions as an Inquiry-Based Framework for Ethical Reasoning Issues in a General Education Earth Systems and Climate Change Course

    2014-12-01

    An important objective in general education geoscience courses is to help students evaluate social and ethical issues based upon scientific knowledge. It can be difficult for instructors trained in the physical sciences to design effective ways of including ethical issues in large lecture courses where whole-class discussions are not practical. The Quality Enhancement Plan for James Madison University, "The Madison Collaborative: Ethical Reasoning in Action," (http://www.jmu.edu/mc/index.shtml) has identified eight key questions to be used as a framework for developing ethical reasoning exercises and evaluating student learning. These eight questions are represented by the acronym FOR CLEAR and are represented by the concepts of Fairness, Outcomes, Responsibilities, Character, Liberty, Empathy, Authority, and Rights. In this study, we use the eight key questions as an inquiry-based framework for addressing ethical issues in a 100-student general education Earth systems and climate change course. Ethical reasoning exercises are presented throughout the course and range from questions of personal behavior to issues regarding potential future generations and global natural resources. In the first few exercises, key questions are identified for the students and calibrated responses are provided as examples. By the end of the semester, students are expected to identify key questions themselves and justify their own ethical and scientific reasoning. Evaluation rubrics are customized to this scaffolding approach to the exercises. Student feedback and course data will be presented to encourage discussion of this and other approaches to explicitly incorporating ethical reasoning in general education geoscience courses.

    In this paper, a cost-efficient LDPC decoder for DVB-S2 is presented. Based on the Normalized Min-Sum algorithm and the turbo-decoding message-passing (TDMP) algorithm, a dual line-scan scheduling is proposed to enable hardware reusing. Furthermore, we present the solution to the address conflict issue caused by the characteristic of the parity-check matrix defined by DVB-S2 LDPC codes. Based on SMIC 0.13µm standard CMOS process, the LDPC decoder has an area of 12.51mm2. The required operating frequency to meet the throughput requirement of 135Mbps with maximum iteration number of 30 is 105MHz. Compared with the latest published DVB-S2 LDPC decoder, the proposed decoder reduces area cost by 34%.

    More than 1,000 Web-based locus-specific variation databases (LSDBs) are listed on the Website of the Human Genetic Variation Society (HGVS). These individual efforts, which often relate phenotype to genotype, are a valuable source of information for clinicians, patients, and their families, as well as for basic research. The initiators of the Human Variome Project recently recognized that having access to some of the immense resources of unpublished information already present in diagnostic laboratories would provide critical data to help manage genetic disorders. However, there are significant ethical issues involved in sharing these data worldwide. An international working group presents second-generation guidelines addressing ethical issues relating to the curation of human LSDBs that provide information via a Web-based interface. It is intended that these should help current and future curators and may also inform the future decisions of ethics committees and legislators.

    1999-01-01

    Plasma-sprayed mullite (3Al2O3 central dot 2SiO2) and mullite/yttria-stabilized-zirconia (YSZ) dual layer coatings have been developed to protect silicon-based ceramics from environmental attack. Mullite-based coating systems show excellent durability in air. However, in combustion environments, corrosive species such as molten salt or water vapor penetrate through cracks in the coating and attack the Si-based ceramics along the interface, Thus modification of the coating system for enhanced crack-resistance is necessary for long-term durability in combustion environments. Other key durability issues include interfacial contamination and coating/substrate bonding. Interfacial contamination leads to enhanced oxidation and interfacial pore formation, while weak coating/substrate bonding leads to rapid attack of the interface by corrosive species, both of which can cause premature failure of the coating. Interfacial contamination can be minimized by limiting impurities in coating and substrate materials. The interface may be modified to improve the coating/substrate bond.

    With the development of population aging in our country, the incidence of gastrointestinal cancer is increasing. The risk of developing gastrointestinal cancer in elderly over 75 years was 5-6 times and the risk of death of gastrointestinal cancer was 7-8 times of the general population. As compared to non-elderly, the incidence of gastric cancer was not decreased obviously but the total incidence of colorectal cancer was increased more quickly. Therefore, screening of gastrointestinal cancer should be performed in the elderly for early discovery, diagnosis and treatment. Because of the insidious onset of the illness in elderly patients, gastrointestinal cancers are mostly diagnosed at advanced or late stage(stage III( or IIII(). Well differentiated cancer is more common, such as papillary or tubular adenocarcinoma. Lauren type, Borrmann II( or III( are more common in gastric cancer, which are relatively favorable. Compared with non-elderly patients, many elderly patients also suffer from comorbid diseases with higher operation risk and postoperative complication rates. Therefore, we must pay great attention to the perioperative management and the surgical operation for the elderly patients. In this paper, several key issues involved the development trend of incidence and mortality of gastrointestinal cancer, the clinicopathological characteristics, the comorbidity and surgical treatment in the elderly patients with gastrointestinal cancer will be elaborated, aiming at promoting further attention to the clinical therapeutic strategies, management measures and prognostic factors for the elderly patients with gastrointestinal cancer.

    Primary objectives of our work were to spatially delineate post industrial areas of the EU-27 and indicate key environmental, social and economic sensitivity issues for these regions. The density of industrial sites within NUTS-x regions for EU-27 countries was assessed by using CORINE 2000 land cover layer. A development of postindustrial society in Europe represents a strong geographic diversity. There are distinct historical and current differences between regions which form major groups, comprising similar internal characteristics and definable trends in environmental and socioeconomic sense. Regions grouped into postindustrial clusters are fundamentally different from the European average, and are facing specific problems related to global market and political changes. Eastern postindustrial regions can be characterized as socially and economically weak, exhibiting high unemployment rate, low GDP, negative population growth and a strong environmental pressure, represented by a high density of dump sites. Most of the western EU postindustrial areas have been successfully recovered and moved into new economy as shown by most of the indicators. In urban postindustrial zones, however, emission sources of pollutants seem to continually be a major problem--not necessarily in terms of exceeding thresholds, but through a remarkable difference in the amount of pollutants produced relative to other regions.

    Focusing mainly on the United States and Latin America, we aimed to identify the constructions of social reality held by the major stakeholders participating in policy debates about global trade, public health, and health services. In a multi-method, qualitative design, we used three sources of data: research and archival literature, 1980-2004; interviews with key informants who represented major organizations participating in these debates, 2002-2004; and organizational reports, 1980-2004. We targeted several types of organizations: government agencies, international financial institutions (IFIs) and trade organizations, international health organizations, multinational corporations, and advocacy groups. Many governments in Latin America define health as a right and health services as a public good. Thus, the government bears responsibility for that right. In contrast, the US government's philosophy of free trade and promoting a market economy assumes that by expanding the private sector, improved economic conditions will improve overall health with a minimum government provision of health care. US government agencies also view promotion of global health as a means to serve US interests. IFIs have emphasized reforms that include reduction and privatization of public sector services. International health organizations have tended to adopt the policy perspectives of IFIs and trade organizations. Advocacy groups have emphasized the deleterious effects of international trade agreements on public health and health services. Organizational stakeholders hold widely divergent constructions of reality regarding trade, public health, and health services. Social constructions concerning trade and health reflect broad ideologies concerning the impacts of market processes. Such constructions manifest features of "creed," regarding the role of the market in advancing human purposes and meeting human needs. Differences in constructions of trade and health constrain policies to

    NASA's Aeronautics Research Mission Directorate (ARMD) collaborates with the FAA and industry to provide concepts and technologies that enhance the transition to the next-generation air-traffic management system (NextGen). To facilitate this collaboration, ARMD has a series of Airspace Technology Demonstration (ATD) sub-projects that develop, demonstrate, and transitions NASA technologies and concepts for implementation in the National Airspace System (NAS). The second of these sub-projects, ATD-2, is focused on the potential benefits to NAS stakeholders of integrated arrival, departure, surface (IADS) operations. To determine the project objectives and assess the benefits of a potential solution, NASA surveyed NAS stakeholders to understand the existing issues in arrival, departure, and surface operations, and the perceived benefits of better integrating these operations. NASA surveyed a broad cross-section of stakeholders representing the airlines, airports, air-navigation service providers, and industry providers of NAS tools. The survey indicated that improving the predictability of flight times (schedules) could improve efficiency in arrival, departure, and surface operations. Stakeholders also mentioned the need for better strategic and tactical information on traffic constraints as well as better information sharing and a coupled collaborative planning process that allows stakeholders to coordinate IADS operations. To assess the impact of a potential solution, NASA sketched an initial departure scheduling concept and assessed its viability by surveying a select group of stakeholders for a second time. The objective of the departure scheduler was to enable flights to move continuously from gate to cruise with minimal interruption in a busy metroplex airspace environment using strategic and tactical scheduling enhanced by collaborative planning between airlines and service providers. The stakeholders agreed that this departure concept could improve schedule

    The Ecosystem Dynamics Branch of the Fort Collins Science Center offers an interdisciplinary team of talented and creative scientists with expertise in biology, botany, ecology, geology, biogeochemistry, physical sciences, geographic information systems, and remote-sensing, for tackling complex questions about natural resources. As demand for natural resources increases, the issues facing natural resource managers, planners, policy makers, industry, and private landowners are increasing in spatial and temporal scope, often involving entire regions, multiple jurisdictions, and long timeframes. Needs for addressing these issues include (1) a better understanding of biotic and abiotic ecosystem components and their complex interactions; (2) the ability to easily monitor, assess, and visualize the spatially complex movements of animals, plants, water, and elements across highly variable landscapes; and (3) the techniques for accurately predicting both immediate and long-term responses of system components to natural and human-caused change. The overall objectives of our research are to provide the knowledge, tools, and techniques needed by the U.S. Department of the Interior, state agencies, and other stakeholders in their endeavors to meet the demand for natural resources while conserving biodiversity and ecosystem services. Ecosystem Dynamics scientists use field and laboratory research, data assimilation, and ecological modeling to understand ecosystem patterns, trends, and mechanistic processes. This information is used to predict the outcomes of changes imposed on species, habitats, landscapes, and climate across spatiotemporal scales. The products we develop include conceptual models to illustrate system structure and processes; regional baseline and integrated assessments; predictive spatial and mathematical models; literature syntheses; and frameworks or protocols for improved ecosystem monitoring, adaptive management, and program evaluation.

    One of the greatest challenges in the fields of quantum information processing and quantum technologies is the detailed coherent control over each and every constituent of quantum systems with an ever increasing number of particles. Within this endeavor, harnessing of many-body entanglement against the detrimental effects of the environment is a major pressing issue. Besides being an important concept from a fundamental standpoint, entanglement has been recognized as a crucial resource for quantum speed-ups or performance enhancements over classical methods. Understanding and controlling many-body entanglement in open systems may have strong implications in quantum computing, quantum simulations of many-body systems, secure quantum communication or cryptography, quantum metrology, our understanding of the quantum-to-classical transition, and other important questions of quantum foundations. In this paper we present an overview of recent theoretical and experimental efforts to underpin the dynamics of entanglement under the influence of noise. Entanglement is thus taken as a dynamic quantity on its own, and we survey how it evolves due to the unavoidable interaction of the entangled system with its surroundings. We analyze several scenarios, corresponding to different families of states and environments, which render a very rich diversity of dynamical behaviors. In contrast to single-particle quantities, like populations and coherences, which typically vanish only asymptotically in time, entanglement may disappear at a finite time. In addition, important classes of entanglement display an exponential decay with the number of particles when subject to local noise, which poses yet another threat to the already-challenging scaling of quantum technologies. Other classes, however, turn out to be extremely robust against local noise. Theoretical results and recent experiments regarding the difference between local and global decoherence are summarized.

    2010-01-01

    This report identifies key human-performance-related issues associated with Next Generation Air Transportation System (NextGen) research in the NASA NextGen-Airspace Project. Four Research Focus Areas (RFAs) in the NextGen-Airspace Project - namely Separation Assurance (SA), Airspace Super Density Operations (ASDO), Traffic Flow Management (TFM), and Dynamic Airspace Configuration (DAC) - were examined closely. In the course of the research, it was determined that the identified human performance issues needed to be analyzed in the context of NextGen operations rather than through basic human factors research. The main gaps in human factors research in NextGen were found in the need for accurate identification of key human-systems related issues within the context of specific NextGen concepts and better design of the operational requirements for those concepts. By focusing on human-system related issues for individual concepts, key human performance issues for the four RFAs were identified and described in this report. In addition, mixed equipage airspace with components of two RFAs were characterized to illustrate potential human performance issues that arise from the integration of multiple concepts.

  20. Overview of US AID-World Bank-NASA Collaboration to Address Water Management Issues in the MENA Region

    NASA Technical Reports Server (NTRS)

    Habib, Shahid

    2012-01-01

    The World Bank, USAID and NASA have recently established a joint project to study multiple issues pertaining to water related applications in the Middle East North Africa (MENA) region. The main concentration of the project is on utilization of remote sensing data and hydrological models to address crop irrigation and mapping, flood mapping and forecasting, evapotranspiration and drought problems prevalent in this large geographic area. Additional emphases are placed on understanding the climate impact on these areas as well. Per IPCC 2007 report, by the end of this century MENA region is projected to experience an increase of 3 C to 5 C rise in mean temperatures and a 20% decline in precipitation. This poses a serious problem for this geographic zone especially when majority of the hydrological consumption is for the agriculture sector and the remaining amount is for domestic consumption. The remote sensing data from space is one of the best ways to study such complex issues and further feed into the decision support systems. NASA's fleet of Earth Observing satellites offer a great vantage point from space to look at the globe and provide vital signs necessary to maintain healthy and sustainable ecosystem. These observations generate multiple products such as soil moisture, global precipitation, aerosols, cloud cover, normalized difference vegetation index, land cover/use, ocean altimetry, ocean salinity, sea surface winds, sea surface temperature, ozone and atmospheric gases, ice and snow measurements, and many more. All of the data products, models and research results are distributed-via the Internet freely through out the world. This project will utilize several NASA models such as global Land Data Assimilation System (LDAS) to generate hydrological states and fluxes in near real time. These LDAS products will then be further compared with other NASA satellite observations (MODIS, VIIRS, TRMM, etc.) and other discrete models to compare and optimize

    The Federal Energy Regulatory Commission`s (FERC) Order 888 is perhaps the most important and far reaching FERC electricity order in decades. The consequences on the structure of the industry and how the industry is regulated are significant departures from past methods and regulatory philosophy. This will undoubtedly have a dramatic impact on the manner in which state public utility commissions, which are also undergoing or considering dramatic change, regulate their jurisdictional electric utilities. This report summarizes and discusses the actions that the FERC is taking and their profound repercussions on the industry and state commissions. The report is not a comprehensive summary of the entire order. Rather, it is intended to highlight the order`s more important features and discuss what this could mean for the states. The report is organized into eight sections; the first seven address Order 888 and the last section (section 8) addresses Order 889. Section 1 through 5 summarize and discuss the main features of Order 888. Section 6 (on jurisdiction) and Section 7 (on property rights) interpret the likely consequences of the order. Section 8, summarizes the FERC`s Open Access Same Time System (OASIS) and discusses some concerns about its real-world application.

    2003-01-01

    GaSb TPV devices are commonly manufactured by Zn diffusion from the vapour phase on a n-type substrate, leading to very high doping concentrations in a narrow emitter. This fact emphasizes the need of a careful modelling that must include high doping effects to simulate the optoelectronic behaviour of devices. In this work the key parameters that have strong influence on the performance of GaSb TPV devices are underlined, more reliable values are suggested and our first results on the study of the absorption coefficient dependence with p-type high doping concentration are presented.

    2013-09-01

    Effective symposia need two strong legs to stand upon: informative presentations of recent research paired with lively discussion of these topics. Although it is easy for the organizers of a symposium to predict the usefulness of the former, as they select the speakers and their topic areas, guaranteeing productive discussion is a far more difficult task. For the Crop Composition Workshop sponsored by the International Life Sciences Institute's Committee on Food and Biotechnology (ILSI IFBIC), the organizers scheduled four roundtable discussions with preselected questions and with rapporteurs drawn from governmental organizations and public-sector research institutes (the authors). It was also the organizers' intent to let these discussions flow on the basis of the experiences of the participants and pressing issues within the overall debate on the role of crop compositional analysis within safety assessment of biotechnology as it exists now and in the future. The goal of this perspective is to summarize the issues raised, providing references when possible, and to describe the consensus statements reached through the course of these discussions.

    Evolutionary dynamics in nature constitute an immensely complex non-equilibrium process. We review the application of physical models of evolution, by focusing on adaptation, extinction, and ecology. In each case, we examine key concepts by working through examples. Adaptation is discussed in the context of bacterial evolution, with a view toward the relationship between growth rates, mutation rates, selection strength, and environmental changes. Extinction dynamics for an isolated population are reviewed, with emphasis on the relation between timescales of extinction, population size, and temporally correlated noise. Ecological models are discussed by focusing on the effect of spatial interspecies interactions on diversity. Connections between physical processes—such as diffusion, turbulence, and localization—and evolutionary phenomena are highlighted.

    Katz, Jessica; Cochran, Jaquelin

    2015-05-01

    To foster sustainable, low-emission development, many countries are establishing ambitious renewable energy targets for their electricity supply. Because solar and wind tend to be more variable and uncertain than conventional sources, meeting these targets will involve changes to power system planning and operations. Grid integration is the practice of developing efficient ways to deliver variable renewable energy (VRE) to the grid. Good integration methods maximize the cost-effectiveness of incorporating VRE into the power system while maintaining or increasing system stability and reliability. When considering grid integration, policy makers, regulators, and system operators consider a variety of issues, which can be organized into four broad topics: New Renewable Energy Generation, New Transmission, Increased System Flexibility, Planning for a High RE Future.

    Living systems have to constantly sense their external environment and adjust their internal state in order to survive and reproduce. Biological systems, from as complex as the brain to a single E. coli cell, have to process these data in order to make appropriate decisions. How do biological systems sense external signals? How do they process the information? How do they respond to signals? Through years of intense study by biologists, many key molecular players and their interactions have been identified in different biological machineries that carry out these signaling functions. However, an integrated, quantitative understanding of the whole system is still lacking for most cellular signaling pathways, not to say the more complicated neural circuits. To study signaling processes in biology, the key thing to measure is the input-output relationship. The input is the signal itself, such as chemical concentration, external temperature, light (intensity and frequency), and more complex signals such as the face of a cat. The output can be protein conformational changes and covalent modifications (phosphorylation, methylation, etc), gene expression, cell growth and motility, as well as more complex output such as neuron firing patterns and behaviors of higher animals. Due to the inherent noise in biological systems, the measured input-output dependence is often noisy. These noisy data can be analysed by using powerful tools and concepts from information theory such as mutual information, channel capacity, and the maximum entropy hypothesis. This information theory approach has been successfully used to reveal the underlying correlations between key components of biological networks, to set bounds for network performance, and to understand possible network architecture in generating observed correlations. Although the information theory approach provides a general tool in analysing noisy biological data and may be used to suggest possible network architectures in

  14. The Water Risks of Hydraulic Fracturing (Fracking): Key Issues from the New California Assessment

    Gleick, P. H.

    2015-12-01

    A key component of the Water-Energy Nexus is the effort over the past decade or so to quantify the volumes and form of water required for the energy fuel cycle from extraction to generation to waste disposal. The vast majority of the effort in this area has focused on the water needs of electricity generation, but other fuel-cycle components also entail significant water demands and threats to water quality. Recent work for the State of California (managed by the California Council on Science and Technology - CCST) has produced a new state-of-the-art assessment of a range of potential water risks associated with hydraulic fracturing and related oil and gas extraction, including volumetric water demands, methods of disposal of produced water, and aquifer contamination. For example, this assessment produced new information on the disposal of produced water in surface percolation pits and the potential for contamination of local groundwater (see Figure). Understanding these risks raises questions about current production and future plans to expand production, as well as tools used by state and federal agencies to manage these risks. This talk will summarize the science behind the CCST assessment and related policy recommendations for both water and energy managers.

    Wastewater management is not limited to the technology used to collect and treat wastewater. It begins with the early planning phase of building a society and includes considerations of how that society will grow. Therefore, history, culture, religion, and socioeconomy are important components to include in any relevant and integrated studies of wastewater management and reuse. Engineering, health, chemistry, biology, food production, cultural heritage, and the needs of people of all ages should be considered together when making management decisions regarding issues so intimately tied with humanity as water and sanitation. Other escalating challenges such as poverty, food, and water scarcity, migration and instability, flooding and catastrophes, diseases and mortality, etc. should also be considered as part of wastewater management and reuse planning. Emerging contaminants could be associated with the urbanization, modernization, and industrialization of several countries. Several arid countries have developed water security strategies where wastewater reuse is a major component. The existing wastewater treatment technologies in these countries are, in most cases, unable to remove such contaminants which may affect irrigation waters, industrial products, groundwater, etc. People would have to accept that the food on their tables could be irrigated with treated wastewater that they generated a few months ago, even if very advanced technologies were used to treat it. The purpose of this review is to highlight multidisciplinary areas of research on wastewater and to propose applicable and affordable mechanisms by which we may consider wastewater as a legitimate resource.

    The government is planning to introduce free generic and essential medicines in public health facilities. Most people in India buy healthcare from the private sector, a compulsion that accounts for a high proportion of healthcare-related expenditure. To reduce the burden of healthcare costs, the government must improve availability and affordability of generic and essential medicines in the market. It can do so because India's large pharmaceutical industry is a major source of generic medicines worldwide. In this article, we discuss three factors that have impeded access to generic and essential medicines: (1) mistaken notions among policymakers, prescribers and patients about branded drugs and generic drugs in India; (2) high prices of medicines due to the progressive dismantling of the system of regulation of medicine prices, and (3) a drug approval and regulatory system that allows medicines (including fixed dose combinations) of doubtful efficacy, rationale, safety and public health relevance to dominate the market at the cost of access to affordable generic and essential medicines. The consequences of ill-health and wasted expenditure on drugs raise issues of public health ethics.Improving access to essential medicines in India is an urgent public health and ethical imperative. This should include improved public provisioning, a system of regulation of drug prices, and an evidence-based drug approval process. PMID:23697486

    Rising food costs can have major impact on vulnerable households, pushing those least able to cope further into poverty and hunger. On the other hand, provided appropriate policies and infrastructure are in place, higher agricultural prices can also raise farmers’ incomes and rural wages, improve rural economies and stimulate investment for longer-term economic growth. High food prices since 2007 have had both short-term impacts and long-term consequences, both good and bad. This article reviews the evidence of how rising costs have affected global food security since the food price crisis of 2007-2008, and their impact on different categories of households and countries. In light of recent studies, we know more about how households, and countries, cope or not with food price shocks but a number of contentious issues remain. These include the adequacy of current estimates and the interpretation of national and household food and nutrition security indicators. India is a particularly important country in this regard, given the high number of food insecure, the relative weight of India in global estimates of food and nutrition insecurity, and the puzzles that remain concerning the country's reported declining per capita calorie consumption. Competing explanations for what is behind it are not in agreement, but these all point to the importance of policy and programme innovation and greater investment necessary to reach the achievable goal of food and nutrition security for all.

    2012-01-01

    Background: Research in critical care extends from the bench to the bedside, involving multiple departments, specialties, and funding organizations. Because of this diversity, it has been difficult for all stakeholders to collectively identify challenges and establish priorities. Objective: To define a comprehensive agenda for critical care research using input from a broad range of stakeholders to serve as a blueprint for future initiatives. Methods: The Critical Care Societies Collaborative (CCSC), consisting of the leadership of the American Association of Critical-Care Nurses (AACN), the American College of Chest Physicians (ACCP), the American Thoracic Society (ATS), and the Society of Critical Care Medicine (SCCM), joined the U.S. Critical Illness and Injury Trials Group (USCIITG) in forming a task force to define a comprehensive critical care research agenda. This group of 25 identified experts was divided into subgroups to address basic, translational, clinical, implementation, and educational research. The subgroups met via conference calls, and the entire task force met in person for a 2-day session. The result was a detailed discussion of the research priorities that served as the basis for this report. Results: The task force identified challenges, specific priority areas, and recommendations for process improvements to support critical care research. Additionally, four overarching themes emerged: (1) the traditional “silo-ed” approach to critical care research is counterproductive and should be modified; (2) an approach that more effectively links areas of research (i.e., basic and translational research, or clinical research and implementation) should be embraced; (3) future approaches to human research should account for disease complexity and patient heterogeneity; and (4) an enhanced infrastructure for critical care research is essential for future success. Conclusions: This document contains the themes/recommendations developed by a large

    2009-04-01

    Purpose: To develop guidelines for the conduct of Phase III clinical trials of larynx preservation in patients with locally advanced laryngeal and hypopharyngeal cancer. Methods and Materials: A multidisciplinary international consensus panel developed recommendations after reviewing results from completed Phase III randomized trials, meta-analyses, and published clinical reports with updates available through November, 2007. The guidelines were reviewed and approved by the panel. Results: According to the recommendations, the trial population should include patients with T2 or T3 laryngeal or hypopharyngeal squamous cell carcinoma not considered for partial laryngectomy and exclude those with laryngeal dysfunction or age greater than 70 years. Functional assessments should include speech and swallowing. Voice should be routinely assessed with a simple, validated instrument. The primary endpoint should capture survival and function. The panel created a new endpoint: laryngo-esophageal dysfunction-free survival. Events are death, local relapse, total or partial laryngectomy, tracheotomy at 2 years or later, or feeding tube at 2 years or later. Recommended secondary endpoints are overall survival, progression-free survival, locoregional control, time to tracheotomy, time to laryngectomy, time to discontinuation of feeding tube, and quality of life/patient-reported outcomes. Correlative biomarker studies for near-term trials should include estimated glomerular filtration rate, excision repair cross-complementary-1 gene, E-cadherin and {beta}-catenin, epiregulin and amphiregulin, and TP53 mutation. Conclusions: Revised trial designs in several key areas are needed to advance the study of larynx preservation. With consistent methodologies, clinical trials can more effectively evaluate and quantify the therapeutic benefit of novel treatment options for patients with locally advanced laryngeal and hypopharyngeal cancer.

    Plants are natural producers of chemical substances, providing potential treatment of human ailments since ancient times. Some herbal chemicals in medicinal plants of traditional and modern medicine carry the risk of herb induced liver injury (HILI) with a severe or potentially lethal clinical course, and the requirement of a liver transplant. Discontinuation of herbal use is mandatory in time when HILI is first suspected as diagnosis. Although, herbal hepatotoxicity is of utmost clinical and regulatory importance, lack of a stringent causality assessment remains a major issue for patients with suspected HILI, while this problem is best overcome by the use of the hepatotoxicity specific CIOMS (Council for International Organizations of Medical Sciences) scale and the evaluation of unintentional reexposure test results. Sixty five different commonly used herbs, herbal drugs, and herbal supplements and 111 different herbs or herbal mixtures of the traditional Chinese medicine (TCM) are reported causative for liver disease, with levels of causality proof that appear rarely conclusive. Encouraging steps in the field of herbal hepatotoxicity focus on introducing analytical methods that identify cases of intrinsic hepatotoxicity caused by pyrrolizidine alkaloids, and on omics technologies, including genomics, proteomics, metabolomics, and assessing circulating micro-RNA in the serum of some patients with intrinsic hepatotoxicity. It remains to be established whether these new technologies can identify idiosyncratic HILI cases. To enhance its globalization, herbal medicine should universally be marketed as herbal drugs under strict regulatory surveillance in analogy to regulatory approved chemical drugs, proving a positive risk/benefit profile by enforcing evidence based clinical trials and excellent herbal drug quality.

    The tropical upper troposphere and lower stratosphere (UT/LS) contain critical questions for atmospheric chemistry and climate. This region also represents the gateway for constituents entering the middle atmosphere, and contains the Tropical Tropopause Layer (TTL). The concept of a tropopause layer, as opposed to level, recognizes that the composition and motion of air in this region are influenced by a combination of tropospheric and stratospheric processes. The TTL extends vertically from the level of maximum convective outflow (200-250 hPa) to the cold point tropopause or, alternatively, to the highest altitude of convective clouds, which sometimes overshoot the tropopause. The TTL extends meridionally to the subtropical jets and tropopause break. During boreal summer, the jet stream and tropopause break are displaced well to the north, near 45° N, and the thermodynamic characteristics of tropical air extend into midlatitudes. During boreal winter, equatorial tropopause temperatures attain their lowest values. These seasonal variations are climatological features of the TTL that recur from year to year. Interannual variations are of secondary importance compared to climatology. More important are the enormous spatial variations, due to monsoon circulations, that accompany the seasonal evolution of the UT/LS. In order to understand the role of the UT/LS and TTL in Earth's climate system it is essential to understand the climatological behavior of this region and spatial variations of the climatology. Observational sampling of the UT/LS is currently a priority in the US, Europe and Japan. Measurement strategies require guidance on the nature of the UT/LS and the identification of key unanswered questions. Certain questions are particularly amenable to ground-based observations. Such observations serve a two-fold purpose: (i) direct measurement of the UT/LS, and (ii) validation of satellite data in this critical, but difficult to observe, altitude range. Our talk

    The USGS National Seismic Hazard Maps are used in building codes, risk analyses, and decisions for public policies. Buildings, bridges, highways, and utilities built to meet modern seismic design provisions are better able to withstand earthquakes, not only saving lives but also leading to cost-effective designs. The National Seismic Hazard Mapping Project members will update these maps using the best-available science that will be discussed in regional science workshops held during 2012. Some key scientific updates for the Central and Eastern U.S. (CEUS) include: (1) updating the earthquake source models for the New Madrid Seismic Zone - varying the magnitudes and recurrence rates, (2) considering a new source model developed for nuclear facilities by the CEUS Seismic Source Characterization project, (3) updating the earthquake catalog and assessing magnitude uncertainty, and (4) evaluating various ground-motion models based on the ongoing Next Generation Attenuation (NGA) - East project. Updates for the Intermountain West region include: (1) assessing recommendations of the Western States Seismic Policy Council working group, (2) modeling antithetic faults such as the Wasatch and West Valley faults, (3) analyzing fault slip-rate uncertainties, and (4) developing geodetic-based strain models. For the Pacific Northwest region we will assess: (1) new turbidite data that indicates a higher rate of events on the southern Cascadia Subduction Zone, (2) new models defining the width of the seismogenic portion of the Zone, (3) new fault models for the Yakima fold-and-thrust belt region, and (4) new subduction ground-motion models and weights, For California we will consider: (1) the new Uniform California Earthquake Rupture Forecast (UCERF 3) model that allows more fault-to-fault jumps and spatial-temporal clustering, and (2) the new NGA-West 2 models that update the previous ground-motion predictions and include directivity effects.

    Background Migration of health workers from Africa continues to undermine the universal provision of quality health care. South Africa is an epicentre for migration – it exports more health workers to high-income countries than any other African country and imports health workers from its lower-income neighbours to fill the gap. Although an inter-governmental agreement in 2003 reduced the very high numbers migrating from South Africa to the United Kingdom, migration continues to other high-income English-speaking countries and few workers seem to return although the financial incentive to work abroad has lessened. A deeper understanding of reasons for migration from South Africa and post-migration experiences is therefore needed to underpin policy which is developed in order to improve retention within source countries and encourage return. Methods Semi-structured interviews were conducted with 16 South African doctors and nurses who had migrated to the United Kingdom. Interviews explored factors influencing the decision to migrate and post-migration experiences. Results Salary, career progression, and poor working conditions were not major push factors for migration. Many health workers reported that they had previously overcome these issues within the South African healthcare system by migrating to the private sector. Overwhelmingly, the major push factors were insecurity, high levels of crime, and racial tension. Although the wish to work and train in what was perceived to be a first-class care system was a pull factor to migrate to the United Kingdom, many were disappointed by the experience. Instead of obtaining new skills, many (particularly nurses) felt they had become ‘de-skilled’. Many also felt that working conditions and opportunities for them in the UK National Health Service (NHS) compared unfavourably with the private sector in South Africa. Conclusions Migration from South Africa seems unlikely to diminish until the major concerns over security

    Sierra Leone experienced intense transmission of Ebola virus disease (EVD) from May 2014 to November 2015 during which a total of 8,704 confirmed cases and over 3,589 confirmed deaths were reported. Our field observation showed many issues in the EVD data management system, which may have contributed to the magnitude and long duration of the outbreak. In this perspective article, we explain the key issues with EVD data management in the field, and the resulting obstacles in analyzing key epidemiological indicators during the outbreak response work. Our observation showed that, during the latter part of the EVD outbreak, surveillance and data management improved at all levels in the country as compared to the earlier stage. We identified incomplete filling and late arrival of the case investigation forms at data management centers, difficulties in detecting double entries and merging identified double entries in the database, and lack of clear process of how death of confirmed cases in holding, treatment, and community care centers are reported to the data centers as some of challenges to effective data management. Furthermore, there was no consolidated database that captured and linked all data sources in a structured way. We propose development of a new application tool easily adaptable to new occurrences, regular data harmonization meetings between national and district data management teams, and establishment of a data quality audit system to assure good quality data as ways to improve EVD data management during future outbreaks.

    Accurate forecasting of extreme weather requires the use of both regional models as well as global General Circulation Models (GCMs). The regional models have higher resolution and more accurate physics - two critical components needed for properly representing the key convective processes. GCMs, on the other hand, have better depiction of the large-scale environment and, thus, are necessary for properly capturing the important scale interactions. But how to evaluate the models, understand their shortcomings and improve them? Satellite observations can provide invaluable information. And this is where the issues of Big Data come: satellite observations are very complex and have large variety while model forecast are very voluminous. We are developing a system - TCIS - that addresses the issues of model evaluation and process understanding with the goal of improving the accuracy of hurricane forecasts. This NASA/ESTO/AIST-funded project aims at bringing satellite/airborne observations and model forecasts into a common system and developing on-line tools for joint analysis. To properly evaluate the models we go beyond the comparison of the geophysical fields. We input the model fields into instrument simulators (NEOS3, CRTM, etc.) and compute synthetic observations for a more direct comparison to the observed parameters. In this presentation we will start by describing the scientific questions. We will then outline our current framework to provide fusion of models and observations. Next, we will illustrate how the system can be used to evaluate several models (HWRF, GFS, ECMWF) by applying a couple of our analysis tools to several hurricanes observed during the 2013 season. Finally, we will outline our future plans. Our goal is to go beyond the image comparison and point-by-point statistics, by focusing instead on understanding multi-parameter correlations and providing robust statistics. By developing on-line analysis tools, our framework will allow for consistent

    Wind generated electricity is a variable resource. Hydrogen can be generated as an energy storage media, but is costly. Advancements in power electronics and system integration are needed to make a viable system. Therefore, the long-term goal of the efforts at the University of North Dakota is to merge wind energy, hydrogen production, and fuel cells to bring emission-free and reliable power to commercial viability. The primary goals include 1) expand system models as a tool to investigate integration and control issues, 2) examine long-term effects of wind-electrolysis performance from a systematic perspective, and 3) collaborate with NREL and industrial partners to design, integrate, and quantify system improvements by implementing a single power electronics package to interface wild AC to PEM stack DC requirements. This report summarizes the accomplishments made during this project.

    Many communities of color are disproportionately exposed to workplace and community environmental hazards. This article presents the results of a pilot project designed by a university-school-community partnership to develop youth leadership to confront these exposures. Using a popular empowerment education approach, students applied peer education, research, and organizing skills learned in the classroom to community-based internships in a service-learning model. Evaluation results from pretests and posttests, focus groups, and in-depth interviews demonstrated that students shared what they learned about young workers' rights and environmental justice with family and friends. They developed a critical analysis of environmental inequities, created a citywide youth coalition that advocates around legal, educational, and environmental issues affecting youth, and implemented campaigns to enforce child labor laws and to prevent school construction on contaminated land. This multifaceted model can serve as an important foundation to develop youth leaders to influence environmental policies in a variety of communities. PMID:16020622

    Animal-welfare issues are usually portrayed in the media in a black-and-white fashion, with simple, single-perspective solutions proposed for what are often, in fact, complex policy issues. In this article, we argue that animal welfare is a multifaceted international and domestic public-policy issue that must take account of not only scientific, ethical, and economic issues but also religious, cultural, and international trade policy considerations. Management of animal welfare at a government policy level also requires an approach based on incremental change. Such change must be both science based and ethically principled, and the rate of change must recognize both the expectations of society and the constraints on the animal user. Ideally, such change should involve full ownership and buy-in from the affected animal user group. The range of stakeholders involved in the animal-welfare debate includes industry and producer groups, science bodies, and animal-welfare non-governmental organizations and professional groups, including the veterinary and legal professions. The veterinary profession, in particular, is expected to play an animal-welfare leadership role, and we discuss expectation versus reality at both a national and an international level. This latter discussion includes specific reference to the role of the World Organisation for Animal Health (the OIE) as an intergovernmental organization representing 175 countries and details some of the major achievements since the OIE assumed its international animal-welfare standard-setting role in 2002. We also address the role of the veterinary profession at national, regional, and international levels. PMID:20378871

  13. The causality between smoking and lung cancer among groups and individuals: addressing issues in tobacco litigation in South Korea

    This article discusses issues on the causality between smoking and lung cancer, which have been raised during the tobacco litigation in South Korea. It should be recognized that the explanatory ability of risk factor(s) for inter-individual variations in disease occurrence is different from the causal contribution of the risk factor(s) to disease occurrence. The affected subjects of the tobacco litigation in South Korea are lung cancer patients with a history of cigarette smoking. Thus, the attributable fraction of the exposed rather than the population attributable fraction should be used in the tobacco litigation regarding the causal contribution of smoking to lung cancer. Scientific evidence for the causal relationship between smoking and lung cancer is based on studies of individuals and groups, studies in animals and humans, studies that are observational or experimental, studies in laboratories and communities, and studies in both underdeveloped and developed countries. The scientific evidence collected is applicable to both groups and individuals. The probability of causation, which is calculated based on the attributable fraction for the association between smoking and lung cancer, could be utilized as evidence to prove causality in individuals.

    A non-diffracting surface layer exists at any boundary of a crystal and can comprise a mass fraction of several percent in a finely divided solid. This has led to the long-standing issue of amorphous content in standards for quantitative phase analysis (QPA). NIST standard reference material (SRM) 676a is a corundum ({alpha}-Al{sub 2}O{sub 3}) powder, certified with respect to phase purity for use as an internal standard in powder diffraction QPA. The amorphous content of SRM 676a is determined by comparing diffraction data from mixtures with samples of silicon powders that were engineered to vary their specific surface area. Under the (supported) assumption that the thickness of an amorphous surface layer on Si was invariant, this provided a method to control the crystalline/amorphous ratio of the silicon components of 50/50 weight mixtures of SRM 676a with silicon. Powder diffraction experiments utilizing neutron time-of-flight and 25 keV and 67 keV X-ray energies quantified the crystalline phase fractions from a series of specimens. Results from Rietveld analyses, which included a model for extinction effects in the silicon, of these data were extrapolated to the limit of zero amorphous content of the Si powder. The certified phase purity of SRM 676a is 99.02% {+-} 1.11% (95% confidence interval). This novel certification method permits quantification of amorphous content for any sample of interest, by spiking with SRM 676a.

  16. Non-Darcian flow in low-permeability media: key issues related to geological disposal of high-level nuclear waste in shale formations

    2014-05-01

    In clay or other low-permeability media, water flow becomes non-Darcian and characterized by the non-linear relationship between water flux and hydraulic gradient. This work is devoted to addressing a number of key issues related to geological disposal of high-level nuclear waste in clay/shale formations. It is demonstrated that water flow velocity in the damaged zone (often considered as a potential preferential advection paths in a repository) surrounding the tunnel is extremely small, as a result of non-Darcian flow behavior, such that solute transport is dominated by diffusion, rather than advection. The finding is also consistent with the often-observed existence of persistent abnormal pressures in shale formations. While relative permeability is the key parameter for modeling the unsaturated flow process, without incorporating non-Darcian flow behavior, significant errors can occur in the determination of relative permeability values from traditional measurement methods. An approach for dealing with temperature impact on non-Darcian flow and a formulation to calculate non-Darcian water flux in an anisotropic medium are presented, taking into consideration that a geological repository is subject to temperature evolution in the near field as a result of heat generated by nuclear waste, and that shale formations are generally anisotropic.

    Unexpected adverse preclinical findings (APFs) are not infrequently encountered during drug development. Such APFs can be functional disturbances such as QT prolongation, morphological toxicity or carcinogenicity. The latter is of particular concern in conjunction with equivocal genotoxicity results. The toxicologic pathologist plays an important role in recognizing these effects, in helping to characterize them, to evaluate their risk for man, and in proposing measures to mitigate the risk particularly in early clinical trials. A careful scientific evaluation is crucial while termination of the development of a potentially useful drug must be avoided. This first part of the review discusses processes to address unexpected APFs and provides an overview over typical APFs in particular classes of drugs. If the mode of action (MoA) by which a drug candidate produces an APF is known, this supports evaluation of its relevance for humans. Tailor-made mechanistic studies, when needed, must be planned carefully to test one or several hypotheses regarding the potential MoA and to provide further data for risk evaluation. Safety considerations are based on exposure at no-observed-adverse-effect levels (NOAEL) of the most sensitive and relevant animal species and guide dose escalation in clinical trials. The availability of early markers of toxicity for monitoring of humans adds further safety to clinical studies. Risk evaluation is concluded by a weight of evidence analysis (WoE) with an array of parameters including drug use, medical need and alternatives on the market. In the second part of this review relevant examples of APFs will be discussed in more detail. PMID:22272031

    The purpose of the earthquake alert system (EAS) is to outrun the seismic energy released in a large earthquake using a geographically distributed network of strong motion sensors that telemeter data to a rapid CPU-processing station, which then issues an area-wide warning to a region before strong motion will occur. The warning times involved are short, from 0 to 30 seconds or so; consequently, most responses must be automated. The San Francisco Bay Area is particularly well suited for an EAS because (1) large earthquakes have relatively shallow hypocenters (10- to 20-kilometer depth), giving favorable ray-path geometries for larger warning times than deeper from earthquakes, and (2) the active faults are few in number and well characterized, which means far fewer geographically distributed strong motion sensors are (about 50 in this region). An EAS prototype is being implemented in the San Francisco Bay Area. The system consists of four distinct subsystems: (1) a distributed strong motion seismic network, (2) a central processing station, (3) a warning communications system and (4) user receiver and response systems. We have designed a simple, reliable, and inexpensive strong motion monitoring station that consists of a three-component Analog Devices ADXLO5 accelerometer sensing unit, a vertical component weak motion sensor for system testing, a 16-bit digitizer with multiplexing, and communication output ports for RS232 modem or radio telemetry. The unit is battery-powered and will be sited in fire stations. The prototype central computer analysis system consists of a PC dam-acquisition platform that pipes the incoming strong motion data via Ethernet to Unix-based workstations for dam processing. Simple real-time algorithms, particularly for magnitude estimation, are implemented to give estimates of the time since the earthquake`s onset its hypocenter location, its magnitude, and the reliability of the estimate. These parameters are calculated and transmitted

    This paper has studied the key issues about integration of GNSS and strong-motion records for real-time earthquake monitoring. The validations show that the consistence of the coordinate system must be considered firstly to exclude the system bias between GNSS and strong-motion. The GNSS sampling rate is suggested about 1-5 Hz, and we should give the strong-motion's baseline shift with a larger dynamic noise as its variation is very swift. The initialization time of solving the baseline shift is less than one minute, and ambiguity resolution strategy is not greatly improved the solution. The data quality is very important for the solution, we advised to use multi-frequency and multi-system observations. These ideas give an important guide for real-time earthquake monitoring and early warning by the tight integration of GNSS and strong-motion records.

    In a series of articles and a health-risk assessment report, scientists at the CIIT Hamner Institutes developed a model (CIIT model) for estimating respiratory cancer risk due to inhaled formaldehyde within a conceptual framework incorporating extensive mechanistic information and advanced computational methods at the toxicokinetic and toxicodynamic levels. Several regulatory bodies have utilized predictions from this model; on the other hand, upon detailed evaluation the California EPA has decided against doing so. In this article, we study the CIIT model to identify key biological and statistical uncertainties that need careful evaluation if such two-stage clonal expansion models are to be used for extrapolation of cancer risk from animal bioassays to human exposure. Broadly, these issues pertain to the use and interpretation of experimental labeling index and tumor data, the evaluation and biological interpretation of estimated parameters, and uncertainties in model specification, in particular that of initiated cells. We also identify key uncertainties in the scale-up of the CIIT model to humans, focusing on assumptions underlying model parameters for cell replication rates and formaldehyde-induced mutation. We discuss uncertainties in identifying parameter values in the model used to estimate and extrapolate DNA protein cross-link levels. The authors of the CIIT modeling endeavor characterized their human risk estimates as “conservative in the face of modeling uncertainties.” The uncertainties discussed in this article indicate that such a claim is premature.

    Background: In Burkina Faso, a comprehensive 35-month radio campaign addressed key, multiple family behaviors for improving under-5 child survival and was evaluated using a repeated cross-sectional, cluster randomized design. The primary outcome of the trial was postneonatal under-5 child mortality. This paper reports on behavior change achieved at midline. Method: Fourteen community radio stations in 14 geographic areas were selected based on their high listenership. Seven areas were randomly allocated to receive the intervention while the other 7 areas served as controls. The campaign was launched in March 2012. Cross-sectional surveys of about 5,000 mothers of under-5 children, living in villages close to the radio stations, were conducted at baseline (from December 2011 to February 2012) and at midline (in November 2013), after 20 months of campaigning. Statistical analyses were based on cluster-level summaries using a difference-in-difference (DiD) approach and adjusted for imbalances between arms at baseline. In addition, routine health facility data were analyzed for evidence of changes in health facility utilization. Results: At midline, 75% of women in the intervention arm reported recognizing radio spots from the campaign. There was some evidence of the campaign having positive effects on care seeking for diarrhea (adjusted DiD, 17.5 percentage points; 95% confidence interval [CI], 2.5 to 32.5; P = .03), antibiotic treatment for fast/difficult breathing (adjusted DiD, 29.6 percentage points; 95% CI, 3.5 to 55.7; P = .03), and saving money during pregnancy (adjusted DiD, 12.8 percentage points; 95% CI, 1.4 to 24.2; P = .03). For other target behaviors, there was little or no evidence of an impact of the campaign after adjustment for baseline imbalances and confounding factors. There was weak evidence of a positive correlation between the intensity of broadcasting of messages and reported changes in target behaviors. Routine health facility data

  4. Incentive-Based Conservation Programs in Developing Countries: A Review of Some Key Issues and Suggestions for Improvements

    2006-01-01

    Biodiversity conservation in developing countries has been a challenge because of the combination of rising human populations, rapid technological advances, severe social hardships, and extreme poverty. To address the social, economic, and ecological limitations of people-free parks and reserves, incentives have been incorporated into conservation programs in the hopes of making conservation meaningful to local people. However, such incentive-based programs have been implemented with little consideration for their ability to fulfill promises of greater protection of biodiversity. Evaluations of incentive-based conservation programs indicate that the approach continually falls short of the rhetoric. This article provides an overview of the problems associated with incentive-based conservation approaches in developing countries. It argues that existing incentive-based programs (IBPs) have yet to realize that benefits vary greatly at different “community” scales and that a holistic conceptualization of a community is essential to incorporate the complexities of a heterogeneous community when designing and implementing the IBPs. The spatial complexities involved in correctly identifying the beneficiaries in a community and the short-term focus of IBPs are two major challenges for sustaining conservation efforts. The article suggests improvements in three key areas: accurate identification of “target” beneficiaries, greater inclusion of marginal communities, and efforts to enhance community aptitudes.

    An experimental and computational study, consisting of modeling and simulation (M&S), of key thermal-mechanical issues affecting the design and safety of pebble-bed (PB) reactors was conducted. The objective was to broaden understanding and experimentally validate thermal-mechanic phenomena of nuclear grade graphite, specifically, spheres in frictional contact as anticipated in the bed under reactor relevant pressures and temperatures. The contact generates graphite dust particulates that can subsequently be transported into the flowing gaseous coolent. Under postulated depressurization transients and with the potential for leaked fission products to be adsorbed onto graphite 'dust', there is the potential for fission products to escape from the primary volume. This is a design safety concern. Furthermore, earlier safety assessment identified the distinct possibility for the dispersed dust to combust in contact with air if sufficient conditions are met. Both of these phenomena were noted as important to design review and containing uncertainty to warrant study. The team designed and conducted two separate effects tests to study and benchmark the potential dust-generation rate, as well as study the conditions under which a dust explosion may occure in a standardized, instrumented explosion chamber.

    This paper analyses the design and impact of capacity building programmes aimed at enhancing capacities of riparian professionals to address and resolve transboundary issues in international river basins. Case study is a programme developed by the Mekong River Commission (MRC). A post training evaluation was applied to assess its impact in terms of individual capacity enhancement and change (use and application of knowledge, factors hampering application, and change in function and opportunities within their organisation). The design of the Capacity Building Programme of the MRC Flood Management and Mitigation Programme showed a well balanced range of subjects (such as IWRM, models and decision support systems and international water law) which are required for such an integrated topic. The post training evaluation, 6 months after the last training workshop, showed the increase in familiarity of the topics for all 37 respondents, with highest increase for the respondents with few years of working experience and from training and educational institutions. The relevance of the subjects taught is shown by the fact that 95% of the respondents indicated they saw the relevance of the subjects and 78% had already used some knowledge acquired in their job. The respondents also indicated that they did not have sufficient opportunities to apply all knowledge acquired. The phased implementation and training of lecturers during the training workshops, had a good impact, directly through increasing involvement in facilitation and delivery of the capacity building programme and through the use of the knowledge gained in short courses and development of curricula at their training institute. For these types of capacity building programmes, a few recommendations can be made. The selection of participants is crucial for the application of the learned knowledge in their work.

    Understanding how to source agricultural raw materials sustainably is challenging in today's globalized food system given the variety of issues to be considered and the multitude of suggested indicators for representing these issues. Furthermore, stakeholders in the global food system both impact these issues and are themselves vulnerable to these issues, an important duality that is often implied but not explicitly described. The attention given to these issues and conceptual frameworks varies greatly--depending largely on the stakeholder perspective--as does the set of indicators developed to measure them. To better structure these complex relationships and assess any gaps, we collate a comprehensive list of sustainability issues and a database of sustainability indicators to represent them. To assure a breadth of inclusion, the issues are pulled from the following three perspectives: major global sustainability assessments, sustainability communications from global food companies, and conceptual frameworks of sustainable livelihoods from academic publications. These terms are integrated across perspectives using a common vocabulary, classified by their relevance to impacts and vulnerabilities, and categorized into groups by economic, environmental, physical, human, social, and political characteristics. These issues are then associated with over 2,000 sustainability indicators gathered from existing sources. A gap analysis is then performed to determine if particular issues and issue groups are over or underrepresented. This process results in 44 "integrated" issues--24 impact issues and 36 vulnerability issues--that are composed of 318 "component" issues. The gap analysis shows that although every integrated issue is mentioned at least 40% of the time across perspectives, no issue is mentioned more than 70% of the time. A few issues infrequently mentioned across perspectives also have relatively few indicators available to fully represent them. Issues in the

    The proposed research will develop systematic sets of uniaxial and multiaxial experimental data at a very high temperature (850-950°C) for Alloy 617. The loading histories to be prescribed in the experiments will induce creep-fatigue and creep-ratcheting failure mechanisms. These experimental responses will be scrutinized in order to quantify the influences of temperature and creep on fatigue and ratcheting failures. A unified constitutive model (UCM) will be developed and validated against these experimental responses. The improved UCM will be incorporated into the widely used finite element commercial software packages ANSYS. The modified ANSYS will be validated so that it can be used for evaluating the very high temperature ASME-NH design-by-analysis methodology for Alloy 617 and thereby addressing the ASME-NH design code issues.

    To improve health at the human, animal, and ecosystem interface, defined as One Health, training of researchers must transcend individual disciplines to develop a new process of collaboration. The transdisciplinary research approach integrates frameworks and methodologies beyond academic disciplines and includes involvement of and input from policy makers and members of the community. The authors argue that there should be a significant shift in academic institutions’ research capacity to achieve the added value of a transdisciplinary approach for addressing One Health problems. This Perspective is a call to action for academic institutions to provide the foundations for this salient shift. The authors begin by describing the transdisciplinary approach, propose methods for building transdisciplinary research capacity, and highlight three value propositions that support the case. Examples are provided to illustrate how the transdisciplinary approach to research adds value through improved sustainability of impact, increased cost-effectiveness, and enhanced abilities to mitigate potentially harmful unintended consequences. The authors conclude with three key recommendations for academic institutions: (1) a focus on creating enabling environments for One Health and transdisciplinary research, (2) the development of novel funding structures for transdisciplinary research, and (3) training of “transmitters” using real-world-oriented educational programs that break down research silos through collaboration across disciplines.

    Despite a severe regulation concerning the building in flooding areas, 80% of these areas are already built in the Greater Paris (Paris, Val-de-Marne, Hauts-de-Seine and Seine-Saint-Denis). The land use in flooding area is presented as one of the main solutions to solve the ongoing real estate pressure. For instance some of the industrial wastelands located along the river are currently in redevelopment and residential buildings are planned. So landuse in the flooding areas is currently a key issue in the development of the Greater Paris area. Tools and measures, structural or non-structural such as warning systems, barriers, etc do exist and could be a smart way to improve the resilience of the new urbanised areas. The technical solutions are available and efficient, but we notice that these tools are not much implemented. There is a lack of flood risk concern among the stakeholders and the inhabitants1. How landuse stakeholders could integrate the flood risk in the decision making process throughout the implementation of the urban project? Which type of governance favours an efficient development of good flood risk policy including prevention, protection and the management of the crisis? What is the "good" governance of the urban project e.g. enabling to take into account or not to forget the flood risk and to empower the (future) inhabitants? This inhabitants' empowerment includes the improvement of awareness (i.e. inhabitants being aware that they live in a flooded area) and the improvement of concern (i.e. inhabitants adopting the "right" behaviour when the risk occurs). In order to investigate how flood risk is or could be integrated in the project governance, we interviewed stakeholders (elected representatives, architects, property developers, etc.) and observed the integration or the vanishing of the risk throughout the project. In order to develop this topic we rely on a case study. The "Ardoines" is a project aiming at redeveloping an industrial site

    Currently, there is no consensus regarding services required to help families with consanguineous marriages manage their increased genetic reproductive risk. Genetic services for communities with a preference for consanguineous marriage in the UK remain patchy, often poor. Receiving two disparate explanations of the cause of recessive disorders (cousin marriage and recessive inheritance) leads to confusion among families. Further, the realisation that couples in non-consanguineous relationships have affected children leads to mistrust of professional advice. British Pakistani families at-risk for recessive disorders lack an understanding of recessive disorders and their inheritance. Such an understanding is empowering and can be shared within the extended family to enable informed choice. In a three-site qualitative study of British Pakistanis, we explored family and health professional perspectives on recessively inherited conditions. Our findings suggest, firstly, that family networks hold strong potential for cascading genetic information, making the adoption of a family-centred approach an efficient strategy for this community. However, this is dependent on provision of high-quality and timely information from health care providers. Secondly, families' experience was of ill-coordinated and time-starved services, with few having access to specialist provision from Regional Genetics Services; these perspectives were consistent with health professionals' views of services. Thirdly, we confirm previous findings that genetic information is difficult to communicate and comprehend, further complicated by the need to communicate the relationship between cousin marriage and recessive disorders. A communication tool we developed and piloted is described and offered as a useful resource for communicating complex genetic information. PMID:26363620

    Introduction The extraordinary feat of proving the effectiveness of oral pre-exposure prophylaxis (PrEP) in clinical trials in different populations in a variety of settings may prove to have been easier than ensuring it is used well. Decision-makers must make difficult choices to realize the promise of antiretroviral prophylaxis for their countries. This paper outlines key economic, regulatory and distributive justice issues that must be addressed for effective and acceptable PrEP implementation. Discussion In considering the role that PrEP can play in combination prevention programmes, decision-makers must determine who can benefit most from PrEP, how PrEP can be provided safely and efficiently, and what kind of health system support will ensure successful implementation. To do this, they need contextualized information on disease burden by population, analyses of how PrEP services might best be delivered, and projections of the human resource and infrastructure requirements for each potential delivery model. There are cost considerations, varying cost-effectiveness results and regulatory challenges. The principles of ethics can inform thorny discussions about who should be prioritized for oral PrEP and how best to introduce it fairly. We describe the cost-effectiveness of PrEP in different populations at higher risk of HIV exposure, its price in low- and middle-income countries, and the current regulatory situation. We explore the principles of ethics that can inform resource allocation decision-making about PrEP anchored in distributive justice, at a time when universal access to antiretroviral treatment remains to be assured. We then highlight the role of advocacy in moving the PrEP agenda forward. Conclusions The time is ripe now for decisions about whether, how and for whom PrEP should be introduced into a country's HIV response. It has the potential to contribute significantly to high impact HIV prevention if it is tailored to those who can most benefit

    The objective of this project is to develop a modeling system to allow operators and regulators to plan all aspects of water management activities associated with shale gas development in the target project area of New York, Pennsylvania, and West Virginia (target area ), including water supply, transport, storage, use, recycling, and disposal and which can be used for planning, managing, forecasting, permit tracking, and compliance monitoring. The proposed project is a breakthrough approach to represent the entire shale gas water lifecycle in one comprehensive system with the capability to analyze impacts and options for operational efficiency and regulatory tracking and compliance, and to plan for future water use and disposition. It will address all of the major water-related issues of concern associated with shale gas development in the target area, including water withdrawal, transport, storage, use, treatment, recycling, and disposal. It will analyze the costs, water use, and wastes associated with the available options, and incorporate constraints presented by permit requirements, agreements, local and state regulations, equipment and material availability, etc. By using the system to examine the water lifecycle from withdrawals through disposal, users will be able to perform scenario analysis to answer "what if" questions for various situations. The system will include regulatory requirements of the appropriate state and regional agencies and facilitate reporting and permit applications and tracking. These features will allow operators to plan for more cost effective resource production. Regulators will be able to analyze impacts of development over an entire area. Regulators can then make informed decisions about the protections and practices that should be required as development proceeds. This modeling system will have myriad benefits for industry, government, and the public. For industry, it will allow planning all water management operations for a

    2016-01-01

    Ambient heat exposure is a well-known health hazard, which reduces human performance and work capacity at heat levels already common in tropical and subtropical areas. Various health problems have been reported. Increasing heat exposure during the hottest seasons of each year is a key feature of global climate change. Heat exhaustion and reduced human performance are often overlooked in climate change health impact analysis. Later this century, many among the four billion people who live in hot areas worldwide will experience significantly reduced work capacity owing to climate change. In some areas, 30-40% of annual daylight hours will become too hot for work to be carried out. The social and economic impacts will be considerable, with global gross domestic product (GDP) losses greater than 20% by 2100. The analysis to date is piecemeal. More analysis of climate change-related occupational health impact assessments is greatly needed. PMID:26989826

  9. Hydrodynamics of coalbed methane reservoirs in the Black Warrior Basin: Key to understanding reservoir performance and environmental issues

    The Black Warrior Basin of the southeastern United States hosts one of the world's most prolific and long-lived coalbed methane plays, and the wealth of experience in this basin provides insight into the relationships among basin hydrology, production performance, and environmental issues. Along the southeast margin of the basin, meteoric recharge of reservoir coal beds exposed in an upturned fold limb exerts a strong control on water chemistry, reservoir pressure, and production performance. Fresh-water plumes containing Na-HCO3 waters with low TDS content extend from the structurally upturned basin margin into the interior of the basin. Northwest of the plumes, coal beds contain Na-Cl waters with moderate to high-TDS content. Carbon isotope data from produced gas and mineral cements suggest that the fresh-water plumes have been the site of significant bacterial activity and that the coalbed methane reservoirs contain a mixture of thermogenic and late-stage biogenic gases. Water produced from the fresh-water plumes may be disposed safely at the surface, whereas underground injection has been used locally to dispose of highly saline water. Wells in areas that had normal hydrostatic reservoir pressure prior to development tend to produce large volumes of water and may take up to 4 a to reach peak gas production. In contrast, wells drilled in naturally underpressured areas distal to the fresh-water plumes typically produce little water and achieve peak gas rates during the first year of production. Environmental debate has focused largely on issues associated with hydrologic communication between deep reservoir coal beds and shallow aquifers. In the coalbed methane fields of the Black Warrior Basin, a broad range of geologic evidence suggests that flow is effectively confined within coal and that the thick intervals of marine shale separating coal zones limit cross-formational flow. ?? 2007 Elsevier Ltd.

  11. Key issues in essential tremor genetics research: Where are we now and how can we move forward?

    2013-01-01

    Background Genetics research is an avenue towards understanding essential tremor (ET). Advances have been made in genetic linkage and association: there are three reported ET susceptibility loci, and mixed but growing data on risk associations. However, causal mutations have not been forthcoming. This disappointing lack of progress has opened productive discussions on challenges in ET and specifically ET genetics research, including fundamental assumptions in the field. Methods This article reviews the ET genetics literature, results to date, the open questions in ET genetics and the current challenges in addressing them. Results Several inherent ET features complicate genetic linkage and association studies: high potential phenocopy rates, inaccurate tremor self-reporting, and ET misdiagnoses are examples. Increasing use of direct examination data for subjects, family members, and controls is one current response. Smaller moves towards expanding ET phenotype research concepts into non-tremor features, clinically disputed ET subsets, and testing phenotype features instead of clinical diagnosis against genetic data are gradually occurring. The field has already moved to considering complex trait mechanisms requiring detection of combinations of rare genetic variants. Hypotheses may move further to consider novel mechanisms of inheritance, such as epigenetics. Discussion It is an exciting time in ET genetics as investigators start moving past assumptions underlying both phenotype and genetics experimental contributions, overcoming challenges to collaboration, and engaging the ET community. Multicenter collaborative efforts comprising rich longitudinal prospective phenotype data and neuropathologic analysis combined with the latest in genetics experimental design and technology will be the next wave in the field.

    Many students in secondary schools consider the sciences difficult and unattractive. This applies to physics in particular, a subject in which students attempt to learn and understand numerous theoretical concepts, often without much success. A case in point is the understanding of the concepts current, voltage and resistance in simple electric circuits. In response to these problems, reform initiatives in education strive for a change of the classroom culture, putting emphasis on more authentic contexts and student activities containing elements of inquiry. The challenge then becomes choosing and combining these elements in such a manner that they foster an understanding of theoretical concepts. In this article we reflect on data collected and analyzed from a series of 12 grade 9 physics lessons on simple electric circuits. Drawing from a theoretical framework based on individual (conceptual change based) and socio-cultural views on learning, instruction was designed addressing known conceptual problems and attempting to create a physics (research) culture in the classroom. As the success of the lessons was limited, the focus of the study became to understand which inherent characteristics of inquiry based instruction complicate the process of constructing conceptual understanding. From the analysis of the data collected during the enactment of the lessons three tensions emerged: the tension between open inquiry and student guidance, the tension between students developing their own ideas and getting to know accepted scientific theories, and the tension between fostering scientific interest as part of a scientific research culture and the task oriented school culture. An outlook will be given on the implications for science lessons.

    Sexual violence is known to be highly prevalent, albeit the majority of incidents are not reported to the authorities. It is therefore likely that medical students will encounter very many patients who have experienced sexual violence during their postgraduate careers, although this history may never be disclosed to them. Numerous highly regarded sources have advocated for the inclusion of instruction on the care of the victim of sexual violence in undergraduate medical curricula. Moreover, there has been a call for research to measure the effectiveness of educational strategies addressing the issue of sexual violence at undergraduate level. We present an evaluation of the effectiveness of a reproducible teaching session on care of the victim of sexual violence appropriate for undergraduate medical students, looking specifically at alterations in students' awareness of the key issues involved in patient care and their attitudes to such patients. This research demonstrates that such an educational intervention significantly enhances undergraduate medical students' awareness of the issues involved in patient care and their insight in to myths surrounding sexual violence.

  16. SPOT 5 HRS geometric performances: Using block adjustment as a key issue to improve quality of DEM generation

    NASA Astrophysics Data System (ADS)

    Bouillon, Aurélie; Bernard, Marc; Gigord, Patrick; Orsoni, Alain; Rudowski, Véronique; Baudoin, Alain

    HRS instrument on board of SPOT 5 allows acquisition of stereoscopic pairs in a single pass. Its final purpose is to provide the worldwide database of Digital Terrain Models and Orthoimages, called Reference3D®, with no use of ground control points and a horizontal location specified as 16 m for 90% of the points. The stake is not only to fulfil the HRS' location specification of 50 m in root mean square but to obtain a location performance as best as possible and to check that the instrument can cope with the realisation of the Reference3D® database. That's why HRS has been the subject of specific attention even after the end of SPOT 5 in-flight commissioning phase. This comprehensive paper summarizes the steps jointly taken by CNES, IGN, Spot Image and HRS end-users to calibrate, monitor and validate the HRS image accuracy as well as the accuracy of the final DEM products. First, an overview of HRS on SPOT 5 will be given, with a specific attention paid to the instrument geometry and rigorous sensor model available through ancillary data given with the images. Then, methods and means used by the French Space Agency (CNES) and the French Mapping Agency (IGN) to reach the objectives will be described and the final accuracy reached will be given. It concerns: calibration and monitoring of the HRS geometrical parameters, and the several on board improvements brought to the satellite by CNES to improve the location accuracy at the single pair level (i.e. no tie points nor ground control points used); the HRS block adjustment model calibration and the evaluation performed by IGN at the stereo pair level (i.e with tie points used within the pair) and block level (with tie points used between different HRS strips). Finally, the article deals with several comparisons of HRS DEM's against available DEMs (eg. SRTM DTED level 2) and also reviews various evaluations of the HRS and the Reference3D® products made by independent users against ground truth issued from field

  4. Key process issues in Cognitive Behavioral Analysis System of Psychotherapy (CBASP): translation of an evidence-based model into clinical practice and training.

    PubMed

    Vivian, Dina; Salwen, Jessica

    2013-09-01

    Our "desired outcome" in writing this article was to present not only key process issues stemming from the Cognitive Behavioral Analysis System of Psychotherapy (CBASP; McCullough, 2000), but to highlight those therapy maneuvers that we, a "seasoned" clinician/supervisor and a clinical trainee, find most useful in delivering treatment and in conducting supervision. We strongly believe that it is only through the translation of evidence-based therapeutic models, such as CBASP, into effective training that a true integration of science and practice can be obtained. Thus, the congruence of trainer's and trainee's views on what constitute top process issues in therapy is important in evaluating the reliability of a therapy model; with this in mind, we focus on three process issues, as follows: (1) problems are anchored to the "here and now" and to specific situational outcomes; (2) patients are encouraged to identify the role they play in affecting their distressing outcomes and to take responsibility for "fixing" them; and (3) the therapist planfully engages in the process of change via disciplined personal involvement. Research and theory supporting these maneuvers are presented, in conjunction with clinical examples. PMID:24000859

    Key management is one of the most important issues in cryptographic systems. Several important challenges in such a context are represented by secure and efficient key generation, key distribution, as well as key revocation. Addressing such challenges requires a comprehensive solution which is robust, secure and efficient. Compared to traditional key management schemes, key management using biometrics requires the presence of the user, which can reduce fraud and protect the key better. In this paper, we propose a novel key management scheme using iris based biometrics. Our newly proposed scheme outperforms traditional key management schemes as well as some existing key-binding biometric schemes in terms of security, diversity and/or efficiency.

    As it has been beautifully demonstrated in synchrotron facilities, water window transmission x-ray microscopy (WW-TXM) has a great potential for high resolution three dimensional (3D) tomographic imaging of frozen cells, without the cumbersome staining and slicing preparation needed by electron microscopy. However, the existing instruments do not exactly meet the expectations of cell biologists in terms of performance and accessibility: 3D images of entire cells grown on a flat substrate with details in the 50-80nm range are necessary for structural cell studies. Functional imaging is also a key issue. Specific molecular probes are widely used to achieve molecular imaging in optical and electron microscopy. The same demand applies to x-ray microscopy. Immediate availability of the observation technique within the biology laboratory is as important as its performance. Therefore, WW-TXM will develop on a wider scale only when table-top instruments become available. We present a detailed analysis of such a microscope. The source is clearly the key element. Laser created plasmas of carbon or nitrogen are a proven but expensive solution. Cerenkov emission in vanadium has been demonstrated as a potential monochromatic source, but we emphasize severe obstacles: huge thermal load and radiation protection. We show that oxygenKα line excitation by an electron beam is a realistic alternative. Being a purely monochromatic source, it would allow the use of a high efficiency mirror condenser, while laser plasmas imply spectral selection with the associated losses. We then describe the main elements of an affordable laboratory microscope, supported by numerical simulations and preliminary experimental work. We also show that functionalized quantum dots, currently used in fluorescence microscopy, are equally detectable with soft x-rays and would allow a dual modality observation. Finally, the expected performance of this prototype is discussed and confronted by the requirements

Introduction At the outset, I should like to acknowledge that part of the title above, which tries to capture the main flavour of this meeting, and has been borrowed from one of the plenary talks at the conference. When we set out to make the programme for the conference, we thought of beginning with observations on the Universe, but then we certainly wanted to go further and address deeper questions, which were at the very foundations of our inquiry, and understanding on the nature and structure of the Universe. I believe, we succeeded to a good extent, and it is all here for you in the form of these Conference Proceedings, which have been aptly titled as 'Vishwa Mimansa', which could be possibly translated as 'Analysis of the Universe'! It is my great pleasure and privilege to welcome you all to the ICGC-2011 meeting at Goa. The International Conference on Gravitation and Cosmology (ICGC) series of meetings are being organized by the Indian Association for General Relativity and Gravitation (IAGRG), and the first such meeting was planned and conducted in Goa in 1987, with subsequent meetings taking place at a duration of about four years at various locations in India. So, it was thought appropriate to return to Goa to celebrate the 25 years of the ICGC meetings. The recollections from that first meeting have been recorded elsewhere here in these Proceedings. The research and teaching on gravitation and cosmology was initiated quite early in India, by V V Narlikar at the Banares Hindu University, and by N R Sen in Kolkata in the 1930s. In course of time, this activity grew and gained momentum, and in early 1969, at the felicitation held for the 60 years of V V Narlikar at a conference in Ahmedabad, P C Vaidya proposed the formation of the IAGRG society, with V V Narlikar being the first President.

    The theme of the 3rd International Conference of the Society of Gynecology and Obstetrics of Nigeria (SOGON) held October 26, 1986 in Enugu was maternal morbidity and mortality in Africa. The opening addresses emphasize the high maternal mortality rate in Africa and SOGON's dedication to promoting women's health and welfare. In order to reduce maternal mortality, the scope of this problem must be made evident by gathering accurate mortality rates through maternity care monitoring and auditing. Governments, health professionals, educators, behavioral scientists, and communication specialists have a responsibility to improve maternal health services in this country. By making the population aware of this problem through education, measures can be taken to reduce the presently high maternal mortality rates. Nigerian women are physically unprepared for childbirth; therefore, balanced diets and disease prevention should be promoted. Since about 40% of deliveries are unmanaged, training for traditional birth attendants should be provided. Furthermore, family planning programs should discourage teenage pregnancies, encourage birth spacing and small families, and promote the use of family planning techniques among men. The problem of child bearing and rearing accompanied by hard work should also be investigated. For practices to change so that maternal mortality rates can be reduced, attitudes must be changed such that the current rates are viewed as unacceptable. PMID:12179275

    Mandatory child abuse reporting laws have developed in particular detail in the United States, Canada, and Australia as a central part of the governments' strategy to detect cases of abuse and neglect at an early stage, protect children, and facilitate the provision of services to children and families. However, the terms of these laws differ in significant ways, both within and between these nations, with the differences tending to broaden or narrow the scope of cases required to be reported and by whom. The purpose of this article is to provide a current and systematic review of mandatory reporting legislation in the 3 countries that have invested most heavily in them to date. A comparison of key elements of these laws is conducted, disclosing significant differences and illuminating the issues facing legislatures and policymaking bodies in countries already having the laws. These findings will also be instructive to those jurisdictions still developing their laws and to those that may, in the future, choose to design a system of mandatory reporting. PMID:18174348

  16. Surface passivation of III-V semiconductors for future CMOS devices—Past research, present status and key issues for future

    Currently, III-V metal-insulator-semiconductor field effect transistors (MISFETs) are considered to be promising device candidates for the so-called "More Moore Approach" to continue scaling CMOS transistors on the silicon platform. Strong interest also exists in III-V nanowire MISFETs as a possible candidate for a "Beyond CMOS"-type device. III-V sensors using insulator-semiconductor interfaces are good candidates for "More Moore"-type of devices on the Si platform. The success of these new approaches for future electronics depends on the availability of a surface passivation technology which can realize pinning-free, high-quality interfaces between insulator and III-V semiconductors. This paper reviews the past history, present status and key issues of the research on the surface passivation technology for III-V semiconductors. First, a brief survey of previous research on surface passivation and MISFETs is made, and Fermi level pinning at insulator-semiconductor interface is discussed. Then, a brief review is made on recent approaches of interface control for high-k III-V MIS structures. Subsequently, as an actual example of interface control, latest results on the authors' surface passivation approach using a silicon interface control layer (Si ICL) are discussed. Finally, a photoluminescence (PL) method to characterize the interface quality is presented as an efficient contactless and non-destructive method which can be applied at each step of interface formation process without fabrication of MIS capacitors and MISFETs.

    Ladies and Gentlemen, it is my great honor and pleasure to present an opening address of the 3rd International Workshop on "State of the Art in Nuclear Cluster Physics"(SOTANCP3). On the behalf of the organizing committee, I certainly welcome all your visits to KGU Kannai Media Center belonging to Kanto Gakuin University, and stay in Yokohama. In particular, to whom come from abroad more than 17 countries, I would appreciate your participations after long long trips from your homeland to Yokohama. The first international workshop on "State of the Art in Nuclear Cluster Physics", called SOTANCP, was held in Strasbourg, France, in 2008, and the second one was held in Brussels, Belgium, in 2010. Then the third workshop is now held in Yokohama. In this period, we had the traditional 10th cluster conference in Debrecen, Hungary, in 2012. Thus we have the traditional cluster conference and SOTANCP, one after another, every two years. This obviously shows our field of nuclear cluster physics is very active and flourishing. It is for the first time in about 10 years to hold the international workshop on nuclear cluster physics in Japan, because the last cluster conference held in Japan was in Nara in 2003, about 10 years ago. The president in Nara conference was Prof. K. Ikeda, and the chairpersons were Prof. H. Horiuchi and Prof. I. Tanihata. I think, quite a lot of persons in this room had participated at the Nara conference. Since then, about ten years passed. So, this workshop has profound significance for our Japanese colleagues. The subjects of this workshop are to discuss "the state of the art in nuclear cluster physics" and also discuss the prospect of this field. In a couple of years, we saw significant progresses of this field both in theory and in experiment, which have brought better and new understandings on the clustering aspects in stable and unstable nuclei. I think, the concept of clustering has been more important than ever. This is true also in the

    The Secretary of India's Ministry of Health and Family Welfare serves as Chair of the Executive Council of the International Institute for Population Sciences in Bombay. She addressed its 35th convocation in 1993. Global population stands at 5.43 billion and increases by about 90 million people each year. 84 million of these new people are born in developing countries. India contributes 17 million new people annually. The annual population growth rate in India is about 2%. Its population size will probably surpass 1 billion by the 2000. High population growth rates are a leading obstacle to socioeconomic development in developing countries. Governments of many developing countries recognize this problem and have expanded their family planning programs to stabilize population growth. Asian countries that have done so and have completed the fertility transition include China, Japan, Singapore, South Korea, and Thailand. Burma, Malaysia, North Korea, Sri Lanka, and Vietnam have not yet completed the transition. Afghanistan, Bangladesh, Iran, Nepal, and Pakistan are half-way through the transition. High population growth rates put pressure on land by fragmenting finite land resources, increasing the number of landless laborers and unemployment, and by causing considerable rural-urban migration. All these factors bring about social stress and burden civic services. India has reduced its total fertility rate from 5.2 to 3.9 between 1971 and 1991. Some Indian states have already achieved replacement fertility. Considerable disparity in socioeconomic development exists among states and districts. For example, the states of Bihar, Madhya Pradesh, Rajasthan, and Uttar Pradesh have female literacy rates lower than 27%, while that for Kerala is 87%. Overall, infant mortality has fallen from 110 to 80 between 1981 and 1990. In Uttar Pradesh, it has fallen from 150 to 98, while it is at 17 in Kerala.

    Ladies and Gentlemen, It is an honor for me to present my welcome address in the 3rd International Workshop on "State of the Art in Nuclear Cluster Physics"(SOTANCP3), as the president of Kanto Gakuin University. Particularly to those from abroad more than 17 countries, I am very grateful for your participation after long long trips from your home to Yokohama. On the behalf of the Kanto Gakuin University, we certainly welcome your visit to our university and stay in Yokohama. First I would like to introduce Kanto Gakuin University briefly. Kanto Gakuin University, which is called KGU, traces its roots back to the Yokohama Baptist Seminary founded in 1884 in Yamate, Yokohama. The seminary's founder was Albert Arnold Bennett, alumnus of Brown University, who came to Japan from the United States to establish a theological seminary for cultivating and training Japanese missionaries. Now KGU is a major member of the Kanto Gakuin School Corporation, which is composed of two kindergartens, two primary schools, two junior high schools, two senior high schools as well as KGU. In this university, we have eight faculties with graduate school including Humanities, Economics, Law, Sciences and Engineering, Architecture and Environmental Design, Human and Environmental Studies, Nursing, and Law School. Over eleven thousands students are currently learning in our university. By the way, my major is the geotechnical engineering, and I belong to the faculty of Sciences and Engineering in my university. Prof. T. Yamada, here, is my colleague in the same faculty. I know that the nuclear physics is one of the most active academic fields in the world. In fact, about half of the participants, namely, more than 50 scientists, come from abroad in this conference. Moreover, I know that the nuclear physics is related to not only the other fundamental physics such as the elementary particle physics and astrophysics but also chemistry, medical sciences, medical cares, and radiation metrology

    Hypertext is a network of information units connected by relational links. A hypertext system is a configuration of hardware and software that presents a hypertext to users and allows them to manage and access the information that it contains. Hypertext is also a user interface concept that closely supports the ways that people use printed information. Hypertext concepts encourage modularity and the elimination of redundancy in data bases because information can be stored only once but viewed in any appropriate context. Hypertext is such a hot idea because it is an enabling technology in that workstations and personal computers finally provide enough local processing power for hypertext user interfaces.

    Heparin is a widely used clinical anticoagulant that is prepared from pig intestine. A contamination of heparin in 2008 has led to a reexamination of animal-derived pharmaceuticals. A bioengineered heparin prepared by bacterial fermentation and chemical and enzymatic processing is currently under development. This study examines the challenges of reducing or removing endotoxins associated with this process that are necessary to proceed with preclinical in vivo evaluation of bioengineered heparin. The current process is assessed for endotoxin levels, and strategies are examined for endotoxin removal from polysaccharides and enzymes involved in this process. PMID:23586950

    Despite widespread agreement that collective action to address shared health challenges across countries is desirable and necessary, the realm of global health governance has remained highly problematic. A key reason for this is the manner in which health issues are presented ('framed'). Because multiple frames are operating simultaneously, confusion and a range of competing policy recommendations and priorities result. Drawing on the previous articles published in this Special Supplement, these key findings explore how health issues are framed, what makes a framing successful, what frames are used for and what effects framing has.

    2003-05-01

    We present a new solution to the known problem of video keying in a natural environment. We segment foreground objects from background objects using their relative distance from the camera, which makes it possible to do away with the use of color for keying. To do so, we developed and built a novel depth video camera, capable of producing RGB and D signals, where D stands for the distance to each pixel. The new RGBD camera enables the creation of a whole new gallery of effects and applications such as multi-layer background substitutions. This new modality makes the production of real time mixed reality video possible, as well as post-production manipulation of recorded video. We address the problem of color spill -- in which the color of the foreground object is mixed, along its boundary, with the background color. This problem prevents an accurate separation of the foreground object from its background, and it is most visible when compositing the foreground objects to a new background. Most existing techniques are limited to the use of a constant background color. We offer a novel general approach to the problem with enabling the use of the natural background, based upon the D channel generated by the camera.

  18. Model or measurements? A discussion of the key issue in Chapman and Pollack's critique of Hamza et al.'s re-evaluation of oceanic heat flux and the global power

    Hofmeister, Anne M.; Criss, Robert E.

    2008-04-01

    Chapman and Pollack (C and P)[2007, Int J Earth Sci] criticize Hamza et al. [2007, Int J Earth Sci] for using actual heat flux measurements in young oceanic crust instead of values from 1-D cooling models. The rationalization of C and P and previous authors is that hydrothermal circulation causes the discrepancy between model and measurement. However, the discrepancy between model values and measured heat flux exists over the entire ocean floor and is opposite to the perturbations that hydrothermal circulation would superimpose on a conductive system [Hofmeister and Criss (2005) Tectonophysics 409:199 203]. The error lies in force-fitting a 1-D cooling model to the 3-D oceanic crust [Hofmeister and Criss (2005) Tectonophysics 395:159 177]. Shortcomings of the 1-D model include mathematical errors, such as use of volumetric rather than linear thermal expansivity to describe contraction which, by assumption, is limited only to the Z -direction [Hofmeister and Criss (2006) Tectonophysics]. This 3× error, traceable to McKenzie and Sclater [1969, Bull Vocanol 33 1:101 118], accidentally provides good agreement of model values with globally averaged seafloor depths for young, but not old ages, and is the sole rationale for using the simplistic cooling model. There is no justification for selective substitution of erroneous 1-D model values for measurements only for the younger half of the 3-D oceanic crust, as stridently and arbitrarily promoted by C and P. Hamza et al. [2007, Int J Earth Sci], in contrast, use the scientific method, which calls for discarding models that do not well describe physical phenomena. The remainder of this report summarizes the shortcomings of cooling models, particularly the half-space cooling (HSC) model touted by C and P, and explains how hydrothermal circulation affects heat flux. We focus on the basics, as these have been misunderstood. With the key issues of C and P being erroneous, it is not necessary to address their remaining

    Understanding how large-scale bioenergy production can affect biodiversity and ecosystems is important if society is to meet current and future sustainable development goals. A variety of bioenergy production systems have been established within different contexts throughout the Pan American region, with wide-ranging results in terms of documented and projected effects on biodiversity and ecosystems. The Pan American region is home to the majority of commercial bioenergy production and therefore the region offers a broad set of experiences and insights on both conflicts and opportunities for biodiversity and bioenergy. This paper synthesizes lessons learned focusing on experiences in Canada, the United States, and Brazil, regarding the conflicts that can arise between bioenergy production and ecological conservation, and benefits that can be derived when bioenergy policies promote planning and more sustainable land management systems. We propose a research agenda to address priority information gaps that are relevant to biodiversity concerns and related policy challenges in the Pan American region.

  4. Addressing Environmental Health Inequalities.

    Gouveia, Nelson

    2016-01-01

    Environmental health inequalities refer to health hazards disproportionately or unfairly distributed among the most vulnerable social groups, which are generally the most discriminated, poor populations and minorities affected by environmental risks. Although it has been known for a long time that health and disease are socially determined, only recently has this idea been incorporated into the conceptual and practical framework for the formulation of policies and strategies regarding health. In this Special Issue of the International Journal of Environmental Research and Public Health (IJERPH), "Addressing Environmental Health Inequalities-Proceedings from the ISEE Conference 2015", we incorporate nine papers that were presented at the 27th Conference of the International Society for Environmental Epidemiology (ISEE), held in Sao Paulo, Brazil, in 2015. This small collection of articles provides a brief overview of the different aspects of this topic. Addressing environmental health inequalities is important for the transformation of our reality and for changing the actual development model towards more just, democratic, and sustainable societies driven by another form of relationship between nature, economy, science, and politics.

    Due to its high specific energy content, liquid hydrogen (LH2) is emerging as an alternative fuel for future aircraft. As a result, there is a need for hydrogen tank storage systems, for these aircraft applications, that are expected to provide sufficient capacity for flight durations ranging from a few minutes to several days. It is understood that the development of a large, lightweight, reusable cryogenic liquid storage tank is crucial to meet the goals of and supply power to hydrogen-fueled aircraft, especially for long flight durations. This report provides an annotated review (including the results of an extensive literature review) of the current state of the art of cryogenic tank materials, structural designs, and insulation systems along with the identification of key challenges with the intent of developing a lightweight and long-term storage system for LH2. The broad classes of insulation systems reviewed include foams (including advanced aerogels) and multilayer insulation (MLI) systems with vacuum. The MLI systems show promise for long-term applications. Structural configurations evaluated include single- and double-wall constructions, including sandwich construction. Potential wall material candidates are monolithic metals as well as polymer matrix composites and discontinuously reinforced metal matrix composites. For short-duration flight applications, simple tank designs may suffice. Alternatively, for longer duration flight applications, a double-wall construction with a vacuum-based insulation system appears to be the most optimum design. The current trends in liner material development are reviewed in the case that a liner is required to minimize or eliminate the loss of hydrogen fuel through permeation.

  8. Public health economics: a systematic review of guidance for the economic evaluation of public health interventions and discussion of key methodological issues

    PubMed Central

    2013-01-01

    Background If Public Health is the science and art of how society collectively aims to improve health, and reduce inequalities in health, then Public Health Economics is the science and art of supporting decision making as to how society can use its available resources to best meet these objectives and minimise opportunity cost. A systematic review of published guidance for the economic evaluation of public health interventions within this broad public policy paradigm was conducted. Methods Electronic databases and organisation websites were searched using a 22 year time horizon (1990–2012). References of papers were hand searched for additional papers for inclusion. Government reports or peer-reviewed published papers were included if they; referred to the methods of economic evaluation of public health interventions, identified key challenges of conducting economic evaluations of public health interventions or made recommendations for conducting economic evaluations of public health interventions. Guidance was divided into three categories UK guidance, international guidance and observations or guidance provided by individual commentators in the field of public health economics. An assessment of the theoretical frameworks underpinning the guidance was made and served as a rationale for categorising the papers. Results We identified 5 international guidance documents, 7 UK guidance documents and 4 documents by individual commentators. The papers reviewed identify the main methodological challenges that face analysts when conducting such evaluations. There is a consensus within the guidance that wider social and environmental costs and benefits should be looked at due to the complex nature of public health. This was reflected in the theoretical underpinning as the majority of guidance was categorised as extra-welfarist. Conclusions In this novel review we argue that health economics may have come full circle from its roots in broad public policy economics. We may

    Traditional encryption, which protects messages from prying eyes, has been used for many decades. The present concepts of encryption are built from that heritage. Utilization of modern software-based encryption techniques implies much more than simply converting files to an unreadable form. Ubiquitous use of computers and advances in encryption technology coupled with the use of wide-area networking completely changed the reasons for utilizing encryption technology. The technology demands a new and extensive infrastructure to support these functions. Full understanding of these functions, their utility and value, and the need for an infrastructure, takes extensive exposure to the new paradigm. This paper addresses issues surrounding the establishment and operation of a key management system (i.e., certification authority) that is essential to the successful implementation and wide-spread use of encryption.

    Key issues that must be considered before a new contraceptive is introduced center on the need for a trained provider to begin or terminate the method, its side effects, duration of use, method's ability to meet users' needs and preferences, and extra training or staff requirements. Logistics and economic issues to consider are identifying a dependable way of effectively supplying commodities, planning extra services needed for the method, and cost of providing the method. Each contraceptive method presents a different side effect pattern and burdens the service delivery setting differently. The strategy developed to introduce or expand the 3-month injectable Depo-Provera (DMPA) can be used for any method. It includes a needs assessment and addresses regulatory issues, service delivery policies and procedures, information and training, evaluation, and other concerns. Viet Nam's needs assessment showed that Norplant should not be introduced until the service delivery system becomes stronger. Any needs assessment for expansion of contraceptive services should cover sexually transmitted disease/HIV issues. A World Health Organization strategy helps officials identify the best method mix for local situations. Introductory strategies must aim to improve the quality of family planning programs and expand choices. Many begin by examining existing data and conducting interviews with policymakers, users, providers, and women's health advocates. Introductory programs for Norplant focus on provider training, adequate counseling and informed consent for users, and ready access to removal. They need a well-prepared service delivery infrastructure. The first phase of the DMPA introductory strategy for the Philippines comprised a social marketing campaign and DMPA introduction at public clinics in 10 pilot areas with strong service delivery. Successful AIDS prevention programs show that people tend to use barrier methods when they are available. USAID is currently studying

    The Florida Keys are a chain of islands, islets and reefs extending from Virginia Key to the Dry Tortugas for about 309 kilometers (192 miles). The keys are chiefly limestone and coral formations. The larger islands of the group are Key West (with its airport), Key Largo, Sugarloaf Key, and Boca Chica Key. A causeway extends from the mainland to Key West.

    This image was acquired on October 28, 2001, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

    NASA Astrophysics Data System (ADS)

    Patton, Mary Chandler

    This critical ethnography deconstructs how one participant researcher came to understand young adults' changing knowledge about water science and environmental issues in an after school program in Colombia. The program intended to empower self-identified young community leaders by teaching participants to engage community members in discourse related to how environmental factors impact one's level of health and quality of life. The data presented in this study illustrate how student participants responded to long-term teacher engagement and to particular curricular components that included hands-on science teaching and social justice coaching. I assessed how student interest in and knowledge of local water ecology and sanitation infrastructure changed throughout the program. Students' responses to the use of technology and digital media were also included in the analysis. The data demonstrates a dramatic change in student's attitudes and perceptions related to their environment and how they feel about their ability to make positive changes in their community.

    2014-03-01

    Ashraf Shady's paper provides a first-hand reflection on how a foreign teacher used cogens as culturally adaptive pedagogy to address cultural misalignments with students. In this paper, Shady drew on several cogen sessions to showcase his journey of using different forms of cogens with his students. To improve the quality of cogens, one strategy he used was to adjust the number of participants in cogens. As a result, some cogens worked and others did not. During the course of reading his paper, I was impressed by his creative and flexible use of cogens and at the same time was intrigued by the question of why some cogens work and not others. In searching for an answer, I found that Mikhail Bakhtin's dialogism, especially the concept of addressivity, provides a comprehensive framework to address this question. In this commentary, I reanalyze the cogen episodes described in Shady's paper in the light of dialogism. My analysis suggests that addressivity plays an important role in mediating the success of cogens. Cogens with high addressivity function as internally persuasive discourse that allows diverse consciousnesses to coexist and so likely affords productive dialogues. The implications of addressivity in teaching and learning are further discussed.

    A key stakeholder perspective, informed by illustrative quantitative and qualitative data, is developed for hospital administrators. These data provide answers to the questions, Who matters to hospitals? and Why do they matter? A tool kit for assessing stakeholders also is presented to help hospital executives identify their institutions' key stakeholders, determine the power of these stakeholders and their core values, and define who within their institutions should be responsible for the routine management of different stakeholders. These tools facilitate the management of each key stakeholder, ensuring that each strategic decision is examined in terms of the likely reaction of key stakeholders and is supplemented with plans for gaining stakeholder acceptance. Managers should recognize that the answers to Who matters? and Why? will vary by type of hospital and by the specific issue being addressed. PMID:10295896

    Recently, Hwang et al. proposed two three-party authenticated quantum key distribution protocols for two communicating parties to establish a session key via a trusted center. They also showed their protocols were secure by using random oracle model. However, their protocols were designed to run in an ideal world. In this paper, we present a more practical protocol by considering some issues, which have not been addressed in their protocols. These issues include (1) session key consistence, (2) online guessing attack, and (3) noise in quantum channels. To deal with these issues, we use error correction code and key evolution. We also give a formal proof for the security of our protocols by using standard reduction, instead of the random oracle model.

    2015-01-01

    Antimicrobial resistance is a serious healthcare concern affecting millions of people around the world. Antiviral resistance has been viewed as a lesser threat than antibiotic resistance, but it is important to consider approaches to address this growing issue. While vaccination is a logical strategy, and has been shown to be successful many times over, next generation viral vaccines with a specific goal of curbing antiviral resistance will need to clear several hurdles including vaccine design, evaluation and implementation. This article suggests that a new model of vaccination may need to be considered: rather than focusing on public health, this model would primarily target sectors of the population who are at high risk for complications from certain infections.

  1. New smart materials to address issues of structural health monitoring.

    SciTech Connect

    Chaplya, Pavel Mikhail

    2004-12-01

    Nuclear weapons and their storage facilities may benefit from in-situ structural health monitoring systems. Appending health-monitoring functionality to conventional materials and structures has been only marginally successful. The purpose of this project was to evaluate feasibility of a new smart material that includes self-sensing health monitoring functions similar to that of a nervous system of a living organism. Reviews of current efforts in the fields of heath-monitoring, nanotechnology, micro-electromechanical systems (MEMS), and wireless sensor networks were conducted. Limitations of the current nanotechnology methods were identified and new approaches were proposed to accelerate the development of self-sensing materials. Wireless networks of MEMS sensors have been researched as possible prototypes of self-sensing materials. Sensor networks were also examined as enabling technologies for dense data collection techniques to be used for validation of numerical methods and material parameter identification. Each grain of the envisioned material contains sensors that are connected in a dendritic manner similar to networks of neurons in a nervous system. Each sensor/neuron can communicate with the neighboring grains. Both the state of the sensor (on/off) and the quality of communication signal (speed/amplitude) should indicate not only a presence of a structural defect but the nature of the defect as well. For example, a failed sensor may represent a through-grain crack, while a lost or degraded communication link may represent an inter-granular crack. A technology to create such material does not exist. While recent progress in the fields of MEMS and nanotechnology allows to envision these new smart materials, it is unrealistic to expect creation of self-sensing materials in the near future. The current state of MEMS, nanotechnology, communication, sensor networks, and data processing technologies indicates that it will take more than ten years for the technologies to mature enough to make self-sensing materials a reality. Nevertheless, recent advances in the field of nanotechnology demonstrate that nanotubes, nanorods, and nanoparticles of carbon, boron and other materials have remarkable mechanical and electrical properties. This would provide. for a plethora of potential applications including self-sensing materials. Record strength-to-weight ratios, ballistic conductivity, and sensing capabilities (i.e., piezo- resistance and piezoelectricity) have been reported for carbon nanotubes. The first transistors, sensors, and actuators have been made from the carbon nanotubes and other nanomaterials. However, nanomaterials are notoriously difficult to manipulate into useful geometries. Nano-manufacturing processes often produce bundles or random networks of nanostructured materials. Samples of the material are then manipulated with advanced microscopy tools to measure properties or to create a single device. This is a laborious and time consuming process. An often overlooked property of the manufactured nanotube bundles is their similarity to the dendritic structure of neural networks with a great quantity of interconnects that may serve as initiation sites for artificial neurons in a self-sensing material nervous system. To accelerate the development of self-sensing materials, future research should concentrate on naturally occurring dendritic nano-structures. While self-sensing materials with subgrain size sensors (scale of micrometers) remain in the realm of basic research, meso-scale (millimeters to centimeters) sensors and their networks are in the state of mature research and have begun to find their way into commercial applications. Macro-scale (centimeters to decimeters) sensors and their networks are commercially available from various sources. The majority of applications that employ sensor networks are driven by the needs of the Department of Defense. Widespread adaptation of sensor networks has been limited by, on one hand, the sensor's high cost of design, development, and deployment, and on the other hand,

    60-NITINOL (60 wt.% Ni - 40 wt.% Ti) is being studied as a material for advanced aerospace components. Frequent wire breakage during electrical-discharge machining of this material was investigated. The studied material was fabricated from hot isostatically pressed 60-NITINOL powder obtained through a commercial source. Bulk chemical analysis of the material showed that the composition was nominal but had relatively high levels of certain impurities, including Al and O. It was later determined that Al2O3 particles had contaminated the material during the hot isostatic pressing procedure and that these particles were the most likely cause of the wire breakage. The results of this investigation highlight the importance of material cleanliness to its further implementation.

    President Barack Obama's State of the Union message, delivered on 24 January, touched on the need for basic research, energy production, support for clean energy, and environmental protection, but it included just one passing reference to climate change. In addition, the speech made no note of the Administration's recent denial of a controversial application for the Keystone XL pipeline to transport crude oil from Canada to the United States and made just an elliptical reference regarding the bankrupt Solyndra Corporation, which the administration had touted as a clean energy company. Innovation "demands basic research," Obama said, adding that Congress should not "gut these investments in our budget." Noting that one promise for innovation is American-made energy, Obama said he is directing the administration to "open more than 75% of our potential offshore oil and gas resources."

  10. Advances in Pediatric Asthma in 2010: Addressing the Major Issues

    Last year’s Advances in Pediatric Asthma concluded with the following statement “If we can close these [remaining] gaps through better communication, improvements in the health care system and new insights into treatment, we will move closer to better methods to intervene early in the course of the disease and induce clinical remission as quickly as possible in most children”. This year’s summary will focus on recent advances in pediatric asthma that take steps moving forward as reported in Journal of Allergy and Clinical Immunology publications in 2010. Some of those recent reports show us how to improve asthma management through steps to better understand the natural history of asthma, individualize asthma care, reduce asthma exacerbations, manage inner city asthma, and some potential new ways to use available medications to improve asthma control. It is clear that we have made many significant gains in managing asthma in children but we have a ways to go to prevent asthma exacerbations, alter the natural history of the disease, and to reduce health disparities in asthma care. Perhaps new directions in personalized medicine and improved health care access and communication will help maintain steady progress in alleviating the burden of this disease in children, especially young children.

    Coastal bays and estuaries are well known for their intrinsic recreational and economic value, yet these ecosystems are also among our most troubled natural environments. Urban development, agriculture, and shipping are just a few examples of human activities that can cause a wide range of deleterious changes within the coastal environment. These alterations, however, occur simultaneously with cycles of natural variability such as climate change. To effectively manage coastal ecosystems, we need to be able to carefully distinguish between anthropogenic and natural causes of change.

  13. Addressing criminality in childhood: is responsivity the central issue?

    Nee, Claire; Ellis, Tom; Morris, Paul; Wilson, Amy

    2013-11-01

    The responsivity principle is the third element of the now well-established risk-need-responsivity (RNR) model of offender rehabilitation. Accruing evidence suggests it is often sacrificed in intervention programs. We aim to demonstrate the central importance of this principle when designing offender interventions by describing the results of a successful, highly responsive intervention for very young children (aged 7 upward) who have offended. A small slice of the offending population as a whole, child offenders are nevertheless tomorrow's serious, violent, and prolific lawbreakers, yet little is understood about what reduces their risk. Recent developments on responsivity are reviewed, before presenting the evaluation indicating significant and sustained drops in risk of recidivism. In-program factors such as the nature and dosage of interventions are examined, alongside outcome data. The article discusses how RNR and other models might apply to this particularly young and underresearched age group. PMID:23070956

  16. Jupiter's Polar Magnetosphere: Outstanding Issues to be Addressed By Juno

    Juno is on course to enter polar orbit at Jupiter on July 4, 2016. After a small number of preliminary orbits during which the orbital period is reduced, approximately 30 science orbits will be executed to explore the interior of Jupiter, hence, its origin. A second primary objective of the mission, and the subject of this talk, is to carry out the first exploration of Jupiter's polar magnetosphere. All previous missions to Jupiter, including Ulysses, remained at low Jovian latitudes at close range, hence, our knowledge of Jupiter's polar magnetosphere is a composite of remote sensing (such as radio emissions in the hectometric and decametric bands as well as IR and UV images); application of observations of Earth's auroral and polar cap particles, fields, and auroral emissions; and modeling. While these likely inform our expectations of what Juno will actually measure qualitatively, Juno will provide the first in depth exploration of auroral processes at another planet, other than a small number of very brief encounters of Saturn's kilometric radio source region by Cassini. With a reasonably complete suite of in situ magnetospheric measurements coupled with remote sensing, Juno will enable us to compare Jupiter's polar magnetosphere with those expectations. Certainly, understanding the nature of auroral currents and mechanisms for particle acceleration are high on the list of priorities for these studies. In addition, it is expected that Juno will greatly improve our understanding of the mapping of auroral processes from high latitudes and low altitudes to the middle and outer magnetosphere.
