    Prichard, R S

    2012-02-01

    Fluorodeoxyglucose (FDG) whole body positron emission computed tomography (PET-CT) detects clinically occult malignancy. The aim of this study was to assess the prevalence and significance of focal thyroid 18F - fluorodeoxyglucose uptake. A retrospective review of all patients who had FDG PET-CT examinations, in a single tertiary referral centre was performed. PET scan findings and the final pathological diagnosis were collated. 2105 scans were reviewed. Focal uptake was identified in 35 (1.66%) patients. Final surgical histology was available on eight patients, which confirmed papillary carcinoma in four (20%) patients and lymphoma and metastatic disease in two patients respectively. This gave an overall malignancy rate in focal thyroid uptake of at least 33%. Thyroid incidentalomas occurred with a frequency of 2.13%, with an associated malignancy rate of at least 33% in focal thyroid uptake. The high malignancy rate associated with focal thyroid uptake mandates further investigation in medically fit patients.

  2. Strategy for future seabed investigations

    Richards, A.F.; Murray, C.N.

    1989-01-01

    The status of seabed disposal studies and possible strategies for future development are reviewed. Background information for strategy development includes presentation of selected recommendations for future studies identified by the NEA/OECD Seabed Working Group, the Engineering Studies Task Group of the Seabed Working Group and the Subseabed Consortium. Inferences from these recommendations, and how sound scientifically based research, significant political perception and technological proof of concept may be related to strategies are considered as a prelude to strategy design. A proposed European strategy, complementary to the 1988 Subseabed Consortium strategy developed in the US, is to proceed to the technological proof of concept by emplacing one or more full-sized waste canisters containing non-radioactive, simulated heat-producing waste by a chosen deployment system. The latter could include the drilled, the penetrator or the pushed-in option. Emplaced canisters would be monitored for an extended period of time, and eventually retrieved for examination. International co-operation and co-ordination of all aspects is recommended. (author)

    1995-01-01

    The synthesis of the geological investigations carried out to date as part of the 'Kristallin' programme has indicated that potentially suitable crystalline rock at an appropriate depth can be found in two regions of Northern Switzerland. The most promising siting options are in Canton Aargau, in a strip of land a few kilometers wide to the south of the Rhine river (Area West: Kaisten-Leuggern-Boettstein). A second-priority option is in Canton Schaffhausen (Area East: Siblingen). For the next phase of investigations into the possibility of locating a repository for high-level and long-lived intermediate-level waste in a crystalline formation, it is planned to carry out a 3D seismic survey in the Boettstein-Leuggern region and to drill an array of inclined boreholes at the former deep borehole site at Leuggern (or Boettstein). These two boreholes have already revealed the presence of large sections of low-permeability crystalline basement. (author) 12 figs

  6. Greenhouse gas reductions; not warranted, not beneficial

    International Nuclear Information System (INIS)

    Green, K.

    2003-01-01

    This report deals with climate change and greenhouse gas emissions, especially regional climate change predictions, from a sceptic's point of view. It rejects all the conventional evidence supporting claims of extreme man-made climate changes, dismissing them as alarmist and inherently uncertain. Similarly, it characterizes policy prescriptions based on this evidence as faulty and as measures which, if implemented, would do both current and future generations considerably more harm than good. Calls for energy efficiency and conservation, reliance on renewable energy sources, improved efficiency of conventional vehicles, hybrid and fuel-cell-driven cars, reducing the amount of driving, establishing greenhouse gas registries, are all dismissed as impractical, imposing higher costs on energy generally, slowing economic growth in the process, and scaring people to adopt unwise public policies by exaggerating the certainty of predictions about man-made climate change. While dismissing the arguments advanced by 'old-school' environmentalists, the report does not question the validity of the overall theory or details of the core greenhouse effect, its main targets are the anthropogenic components of the observed temperature record, and the evidence of a clear cause-and-effect link between anthropogenic forcing and changes in the Earth's surface temperature. Overall, the report dismisses the 'conventional' view of the extent of climate change, the cause of that change and the risk it poses. It emphasizes the limitations on economic freedom that proposed policies would inflict, and argues in favour of more studies to provide the foundation for a societal response based on a solid understanding of the science behind climate change, and the impact of proposed policy options. 32 refs., 2 figs

    One of the complicating factors of the future robotic and human lunar landing missions is the influence of the dust. Meteorites bombardment has accompanied by shock-explosive phenomena, disintegration and mix of the lunar soil in depth and on area simultaneously. As a consequence, the lunar soil has undergone melting, physical and chemical transformations. Recently we have the some reemergence for interest of Moon investigation. The prospects in current century declare USA, China, India, and European Union. In Russia also prepare two missions: Luna-Glob and Luna-Resource. Not last part of investigation of Moon surface is reviewing the dust condition near the ground of landers. Studying the properties of lunar dust is important both for scientific purposes to investigation the lunar exosphere component and for the technical safety of lunar robotic and manned missions. The absence of an atmosphere on the Moon's surface is leading to greater compaction and sintering. Properties of regolith and dust particles (density, temperature, composition, etc.) as well as near-surface lunar exosphere depend on solar activity, lunar local time and position of the Moon relative to the Earth's magneto tail. Upper layers of regolith are an insulator, which is charging as a result of solar UV radiation and the constant bombardment of charged particles, creates a charge distribution on the surface of the moon: positive on the illuminated side and negative on the night side. Charge distribution depends on the local lunar time, latitude and the electrical properties of the regolith (the presence of water in the regolith can influence the local distribution of charge). On light side of Moon near surface layer there exists possibility formation dusty plasma system. Altitude of levitation is depending from size of dust particle and Moon latitude. The distribution dust particle by size and altitude has estimated with taking into account photoelectrons, electrons and ions of solar wind, solar

    Price clustering can be a source of market inefficiency. It follows that searching for price clustering in markets have gone beyond share prices into real estate, interest rate, and exchange rate markets. In this paper, we extend this line of research to oil futures markets. In particular, we consider five different forms of oil futures contracts and test for evidence of price clustering. Our results reveal strong presence of price clustering in the oil futures market. This finding implies that price clustering can potentially be a source of oil market inefficiency, which can influence trading strategies. (author)

  17. The development of future-oriented control: an electrophysiological investigation.

    Science.gov (United States)

    Waxer, Matthew; Morton, J Bruce

    2011-06-01

    Cognitive control, or the ability to focus attention and select task-appropriate responses, is not static but can be dynamically adjusted in the face of changing environmental circumstances. Several models suggest a role for conflict-monitoring in triggering these adjustments, whereby instances of response uncertainty are detected by the anterior cingulate cortex and strengthen attention-guiding rules actively maintained by lateral prefrontal cortex. Given the continued development of active maintenance mechanisms into adolescence, these models predict that the capacity to dynamically modulate control should be protracted in its development. The present study tested this prediction by examining age-related differences in behavioral and electrophysiological adaptations to prior conflict. Children, adolescents, and adults were administered the Dimensional Change Card Sort (DCCS; Zelazo, 2006) - a developmentally-appropriate task modified so that response conflict varied from trial to trial - as cortical activity was measured by means of event-related potentials (ERPs). Although all groups showed a robust conflict effect, there were pronounced age-related differences in behavioral and electrophysiological adaptations to prior conflict. First, responses to incongruent trials were faster following incongruent trials than following congruent trials, but only for adults and adolescents. Second, ERP components that indexed response conflict, and the cortical source of these components, were modulated by preceding conflict for adults and adolescents, but not children. Taken together, the findings suggest that adults and adolescents take advantage of prior conflict to prepare for the future, whereas children respond to cognitive challenges as they occur. Theoretical implications are discussed. Copyright © 2011 Elsevier Inc. All rights reserved.

    The safety of HTR under normal operation and accident conditions, the possibility of inspection, maintenance and repair or decontamination of single primary components as well as the safety of maintenance personnel are essentially determined by the transport- and deposition behaviour of the non gaseous fission - and activation products in the primary loop of the reactor. A comprehensive program has been started in 1969 in KFA in collaboration with various industrial firms and foreign institutions to investigate these problems. The program includes in-pile and out-pile experiments, simulating reactor conditions and also different laboratory experiments and extensive theoretical investigations. The aim of these efforts is to test experimentally the models and computercodes, which are used for prediction of transport and deposition behaviour of fission products for HTR's as well under normal as under accident conditions. Further more a verified dataset is to be established. In this paper a survey is given of the experimental facilities carried out by KFA or in cooperation with KFA

    Experience in applying conventional and epithermal neutron activation analysis for some challenging areas of life sciences and material science is reviewed. For more than 30 years of its operation the radioanalytical complex REGATA at the IBR-2 reactor in Dubna has become a source of analytical data for the environmental studies, marine geology, biotechnology and medicine, technological process of diamond and boron nitride synthesis, archaeology, nanomaterials, etc. In spite of competing non-nuclear analytical techniques (AAS, ICP-ES, ICP-MS, etc.), the reactor neutron activation analysis (NAA) as a primary (ratio) method continues to be the most powerful multielement analytical technique providing quantification of trace elements at ultralow levels. Combined with modern statistical data treatment of large arrays of data, GIS (geographic information system) technologies, electron scanning microscopy, tomography, and others, NAA serves to obtain actual, practical results resumed in the review. The perspectives of using the upgraded reactor IBR-2M for analytical investigations are discussed. (author)

  6. Black-Scholes finite difference modeling in forecasting of call warrant prices in Bursa Malaysia

    Science.gov (United States)

    Mansor, Nur Jariah; Jaffar, Maheran Mohd

    2014-07-01

    Call warrant is a type of structured warrant in Bursa Malaysia. It gives the holder the right to buy the underlying share at a specified price within a limited period of time. The issuer of the structured warrants usually uses European style to exercise the call warrant on the maturity date. Warrant is very similar to an option. Usually, practitioners of the financial field use Black-Scholes model to value the option. The Black-Scholes equation is hard to solve analytically. Therefore the finite difference approach is applied to approximate the value of the call warrant prices. The central in time and central in space scheme is produced to approximate the value of the call warrant prices. It allows the warrant holder to forecast the value of the call warrant prices before the expiry date.

  7. Temperature impacts on economic growth warrant stringent mitigation policy

    Science.gov (United States)

    Moore, Frances C.; Diaz, Delavane B.

    2015-02-01

    Integrated assessment models compare the costs of greenhouse gas mitigation with damages from climate change to evaluate the social welfare implications of climate policy proposals and inform optimal emissions reduction trajectories. However, these models have been criticized for lacking a strong empirical basis for their damage functions, which do little to alter assumptions of sustained gross domestic product (GDP) growth, even under extreme temperature scenarios. We implement empirical estimates of temperature effects on GDP growth rates in the DICE model through two pathways, total factor productivity growth and capital depreciation. This damage specification, even under optimistic adaptation assumptions, substantially slows GDP growth in poor regions but has more modest effects in rich countries. Optimal climate policy in this model stabilizes global temperature change below 2 °C by eliminating emissions in the near future and implies a social cost of carbon several times larger than previous estimates. A sensitivity analysis shows that the magnitude of climate change impacts on economic growth, the rate of adaptation, and the dynamic interaction between damages and GDP are three critical uncertainties requiring further research. In particular, optimal mitigation rates are much lower if countries become less sensitive to climate change impacts as they develop, making this a major source of uncertainty and an important subject for future research.

    This study aims to shed light on some of the most interesting financial oil derivatives issued so far in order to assess the potential of this new wave of innovative funding instruments. In Part I some theoretical background is provided and applied to the problem of the American futures option. The ''binomial'' model for valuing future option contracts is presented and the most accurate alternatives for pricing American futures options are reviewed. The role of these numerical procedures in valuing more complex options involved in oil warrants is examined. Comments are made on the behaviour of volatility, which stands as a key interface between theory and practice in oil trading on the oil futures market. Part II of the study describes in detail some of the most famous new financial oil derivatives. Some final conclusions are drawn on the potential of oil trusts and synthetic oilfields to be involved in project and general funding in the oil industry. (44 figures, 11 tables, 53 references) (UK)

    Full Text Available India's success in producing food and milk for its population (Green Revolution and White Revolution happened because of scientific research and field trials. Likewise improving the health of Indians needs clinical research and clinical trials. A Large proportion of the sick Indians are poor, illiterate with no access to good health care. They are highly vulnerable to inducement and exploitation in clinical trials. The past two decades saw the rise and fall of clinical trials in India. The rise happened when our regulators created a favorable environment, and Indian investigators were invited to participate in global clinical trials. The gap between the demand and supply resulted in inadequate protection of the trial participants. Reports of abuses of the vulnerable trial participants followed by public interest litigations led to strengthening of regulations by the regulators. The stringent new regulations made the conduct of clinical trials more laborious and increased the cost of clinical trials in India. There was a loss of interest in sponsored clinical trials resulting in the fall in global clinical trials in India. Following repeated appeals by the investigators, the Indian regulators have recently relaxed some of the stringent regulations, while continuing to ensure the adequate patient protection. Clinical trials that are relevant to our population and conducted by well-trained investigators and monitored by trained and registered Ethics Committees will increase in the future. We must remain vigilant, avoid previous mistakes, and strive hard to protect the trial participants in the future trials.

    The use of resonant depolarization has been suggested for precise beam energy measurements (better than 100 keV) in the eþe− Future Circular Collider (FCC-eþe−) for Z and WW physics at 45 and 80 GeV beam energy respectively. Longitudinal beam polarization would benefit the Z peak physics program; however it is not essential and therefore it will be not investigated here. In this paper the possibility of selfpolarized leptons is considered. Preliminary results of simulations in presence of quadrupole misalignments and beam position monitors (BPMs) errors for a simplified FCC-eþe− ring are presented.

    Purpose To describe official adult-onset offenders, investigate their antisocial histories and test hypotheses about their origins. Methods We defined adult-onset offenders among 931 Dunedin Study members followed to age 38, using criminal-court conviction records. Results Official adult-onset offenders were 14% of men, and 32% of convicted men, but accounted for only 15% of convictions. As anticipated by developmental theories emphasizing early-life influences on crime, adult-onset offenders’ histories of antisocial behavior spanned back to childhood. Relative to juvenile-offenders, during adolescence they had fewer delinquent peers and were more socially inhibited, which may have protected them from conviction. As anticipated by theories emphasizing the importance of situational influences on offending, adult-onset offenders, relative to non-offenders, during adulthood more often had schizophrenia, bipolar disorder, and alcohol-dependence, had weaker social bonds, anticipated fewer informal sanctions, and self-reported more offenses. Contrary to some expectations, adult-onset offenders did not have high IQ or high socioeconomic-status families protecting them from juvenile conviction. Conclusions A tailored theory for adult-onset offenders is unwarranted because few people begin crime de novo as adults. Official adult-onset offenders fall on a continuum of crime and its correlates, between official non-offenders and official juvenile-onset offenders. Existing theories can accommodate adult-onset offenders. PMID:27134318

    This project discusses about pricing warrant in Malaysia. The Black Scholes model with non-dividend approach and linear interpolation technique was applied in pricing the call warrant. Three call warrants that are listed in Bursa Malaysia were selected randomly from UiTM's datastream. The finding claims that the volatility for each call warrants are different to each other. We have used the historical volatility which will describes the price movement by which an underlying share is expected to fluctuate within a period. The Black Scholes model price that was obtained by the model will be compared with the actual market price. Mispricing the call warrants will contribute to under or over valuation price. Other variables like interest rate, time to maturity date, exercise price and underlying stock price are involves in pricing call warrants as well as measuring the moneyness of call warrants.

  19. Present-day biogeochemical activities of anaerobic bacteria and their relevance to future exobiological investigations

    If the primordial atmosphere was reducing, then the first microbial ecosystem was probably composed of anaerobic bacteria. However, despite the presence of an oxygen-rich atmosphere, anaerobic habitats are important, commonplace components of the Earth's present biosphere. The geochemical activities displayed by these anaerobes impact the global cycling of certain elements (e.g., C, N, S, Fe, Mn, etc.). Methane provides an obvious example of how human-enhanced activities on a global scale can influence the content of a "radiative" (i.e., infrared absorbing) trace gas in the atmosphere. Methane can be oxidized by anaerobic bacteria, but this does not appear to support their growth. Acetylene, however, does support such growth. This may form the basis for future exobiological investigations of the atmospheres of anoxic, hydrocarbon-rich planets like Jupiter and Saturn, as well as the latter's satellite Titan. ?? 1989.

    Preload studies are used to investigate the satiating effects of foods and food ingredients. However, the design of preload studies is complex, with many methodological considerations influencing appetite responses. The aim of this pilot investigation was to determine acceptability, and optimise methods, for a future satiety preload study. Specifically, we investigated the effects of altering (i) energy intake at a standardised breakfast (gender-specific or non-gender specific), and (ii) the duration between mid-morning preload and ad libitum lunch meal, on morning appetite scores and energy intake at lunch. Participants attended a single study visit. Female participants consumed a 214-kcal breakfast ( n  = 10) or 266-kcal breakfast ( n  = 10), equivalent to 10% of recommended daily energy intakes for females and males, respectively. Male participants ( n  = 20) consumed a 266-kcal breakfast. All participants received a 250-ml orange juice preload 2 h after breakfast. The impact of different study timings was evaluated in male participants, with 10 males following one protocol (protocol 1) and 10 males following another (protocol 2). The duration between preload and ad libitum lunch meal was 2 h (protocol 1) or 2.5 h (protocol 2), with the ad libitum lunch meal provided at 12.00 or 13.00, respectively. All female participants followed protocol 2. Visual analogue scale (VAS) questionnaires were used to assess appetite responses and food/drink palatability. Correlation between male and female appetite scores was higher with the provision of a gender-specific breakfast, compared to non-gender-specific breakfast (Pearson correlation of 0.747 and 0.479, respectively). No differences in subjective appetite or ad libitum energy intake were found between protocols 1 and 2. VAS mean ratings of liking, enjoyment, and palatability were all > 66 out of 100 mm for breakfast, preload, and lunch meals. The findings of this pilot study confirm the acceptability

  1. Unreliable patient identification warrants ABO typing at admission to check existing records before transfusion.

    This study describes patient identification errors leading to transfusional near-misses in blood issued by the Alps Mediterranean French Blood Establishment (EFSAM) to Marseille Public Hospitals (APHM) over an 18-month period. The EFSAM consolidates 14 blood banks in southeast France. It supplies 149 hospitals and maintains a centralized database on ABO types used at all area hospitals. As an added precaution against incompatible transfusion, the APHM requires ABO testing at each admission regardless of whether the patient has an ABO record. The study goal was to determine if admission testing was warranted. Discrepancies between ABO type determined by admission testing and records in the centralized database were investigated. The root cause for each discrepancy was classified as specimen collection or patient admission error. Causes of patient admission events were further subclassified as namesake (name similarity) or impersonation (identity fraud). The incidence of ABO discrepancies was 1:2334 including a 1:3329 incidence of patient admission events. Impersonation was the main cause of identity events accounting for 90.3% of cases. The APHM's ABO control policy prevented 19 incompatible transfusions. In relation to the 48,593 packed red cell units transfused, this would have corresponded to a risk of 1:2526. Collecting and storing ABO typing results in a centralized database is an essential public health tool. It allows crosschecking of current test results with past records and avoids redundant testing. However, as patient identification remains unreliable, ABO typing at each admission is still warranted to prevent transfusion errors. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    2013-01-01

    Full Text Available Turbo warrants are liquidly traded financial derivative securities in over-the-counter and exchange markets in Asia and Europe. The structure of turbo warrants is similar to barrier options, but a lookback rebate will be paid if the barrier is crossed by the underlying asset price. Therefore, the turbo warrant price satisfies a partial differential equation (PDE with a boundary condition that depends on another boundary-value problem (BVP of PDE. Due to the highly complicated structure of turbo warrants, their valuation presents a challenging problem in the field of financial mathematics. This paper applies the homotopy analysis method to construct an analytic pricing formula for turbo warrants under stochastic volatility in a PDE framework.

    Future surface missions to Mars and other planetary bodies will benefit from continued advances in miniature sensor and sample handling technologies that enable high-performance chemical analyses of natural samples. Fine-scale (approx.1 mm and below) analyses of rock surfaces and interiors, such as exposed on a drill core, will permit (1) the detection of habitability markers including complex organics in association with their original depositional environment, and (2) the characterization of successive layers and gradients that can reveal the time-evolution of those environments. In particular, if broad-based and highly-sensitive mass spectrometry techniques could be brought to such scales, the resulting planetary science capability would be truly powerful. The Linear Ion Trap Mass Spectrometer (LITMS) investigation is designed to conduct fine-scale organic and inorganic analyses of short (approx.5-10 cm) rock cores such as could be acquired by a planetary lander or rover arm-based drill. LITMS combines both pyrolysis/gas chromatograph mass spectrometry (GCMS) of sub-sampled core fines, and laser desorption mass spectrometry (LDMS) of the intact core surface, using a common mass analyzer, enhanced from the design used in the Mars Organic Molecule Analyzer (MOMA) instrument on the 2018 ExoMars rover. LITMS additionally features developments based on the Sample Analysis at Mars (SAM) investigation on MSL and recent NASA-funded prototype efforts in laser mass spectrometry, pyrolysis, and precision subsampling. LITMS brings these combined capabilities to achieve its four measurement objectives: (1) Organics: Broad Survey Detect organic molecules over a wide range of molecular weight, volatility, electronegativity, concentration, and host mineralogy. (2) Organic: Molecular Structure Characterize internal molecular structure to identify individual compounds, and reveal functionalization and processing. (3) Inorganic Host Environment Assess the local chemical

    1988-01-01

    Within the framework of a joint program initiated in 1983 by the two French Government Agencies C.N.E.S. (Centre National d'Etudes Spatiales) and C.E.A. (Commissariat a l'Energie Atomique), in order to study space nuclear power systems for future ARIANE 5 applications, extensive investigations have dealt with the Brayton cycle which has been selected as the energy conversion system. Several aspects can be mentioned in this field: the matching of the power system to the available radiator dimensions up to 200 kWe, the direct or indirect waste heat transfer to the radiator, the use of a recuperator, the recent work on moderate (25 kWe) power levels, the simulation studies related to various operating conditions and the general system optimization. A limited experimental program is starting on some crucial technology areas including a first contract to the industry concerning the turbogenerator. Particular attention is being paid to the significance of the adoption of a Brayton cycle for space applications involving a nuclear heat source which can be either a liquid metal-cooled or a gas-cooled reactor. As far as a gas-cooled reactor, direct cycle system is concerned, the relevance to the reactor technology and the concept for moderator thermal conditioning, is particularly addressed

    2012-01-01

    The understanding of phase change materials is of great importance because it enables us to predict properties and tailor alloys which might be even better suitable to tackle challenges of future memory applications. Within this thesis two topics have been approached: on the one hand the understanding of the alloy In 3 Sb 1 Te 2 and on the other hand the so called resistivity drift of amorphous Ge-Sn-Te phase change materials. The main topic covers an in depth discussion of the ternary alloy In 3 Sb 1 Te 2 . At first glance, this alloy does not fit into the established concepts of phase alloys: e.g. the existence of resonant bonding in the crystalline phase is not obvious and the number of p-electrons is very low compared to other phase change alloys. Furthermore amorphous phase change alloys with high indium content are usually not discussed in literature, an exception being the recent work by Spreafico et al. on InGeTe 2 . For the first time a complete description of In 3 Sb 1 Te 2 alloy is given in this work for the crystalline phase, amorphous phase and crystallization process. In addition comparisons are drawn to typical phase change materials like Ge 2 Sb 2 Te 5 /GeTe or prototype systems like AgInTe 2 and InTe. The second topic of this thesis deals with the issue of resistivity drift, i.e. the increase of resistivity of amorphous phase change alloys with aging. This drift effect greatly hampers the introduction of multilevel phase change memory devices into the market. Recently a systematic decrease of drift coefficient with stoichiometry has been observed in our group going from GeTe over Ge 3 Sn 1 Te 4 to Ge 2 Sn 2 Te 4 . These alloys are investigated with respect to constraint theory.

  14. Using Scenario Visioning and Participatory System Dynamics Modeling to Investigate the Future: Lessons from Minnesota 2050

    Kathryn J. Draeger

    2010-08-01

    Full Text Available Both scenario visioning and participatory system dynamics modeling emphasize the dynamic and uncontrollable nature of complex socio-ecological systems, and the significance of multiple feedback mechanisms. These two methodologies complement one another, but are rarely used together. We partnered with regional organizations in Minnesota to design a future visioning process that incorporated both scenarios and participatory system dynamics modeling. The three purposes of this exercise were: first, to assist regional leaders in making strategic decisions that would make their communities sustainable; second, to identify research gaps that could impede the ability of regional and state groups to plan for the future; and finally, to introduce more systems thinking into planning and policy-making around environmental issues. We found that scenarios and modeling complemented one another, and that both techniques allowed regional groups to focus on the sustainability of fundamental support systems (energy, food, and water supply. The process introduced some creative tensions between imaginative scenario visioning and quantitative system dynamics modeling, and between creating desired futures (a strong cultural norm and inhabiting the future (a premise of the Minnesota 2050 exercise. We suggest that these tensions can stimulate more agile, strategic thinking about the future.

    Full Text Available The article deals with modern scholars’ approaches to the definition of the term “pedagogical culture of future teachers of musical art”. The authors give their own definition of future teacher’s pedagogical culture. It is defined as a subjectively conditioned system of values, culture-pedagogical knowledge, norms of behavior, which are practically implemented in the process of the development of a human being. These factors contribute to the realization of students’ abilities, development of moral and philosophical personal qualities by means of implementing certain pedagogical conditions of training in higher educational establishments of Ukraine. They also determine the choice of the correct strategy of specialists-educators’ cultural-pedagogical identity in their future professional activity. The criteria and levels as well as the stages of experimental work on the implementation of these methods have been identified and described. The experimental stages of the implementation of methods of formation of future teachers’ pedagogical culture by means of spiritual music have been identified and described. There are three stages: adaptive, cognitive-corrective, and acmeological. The results of experimental work, that demonstrate positive effects of the implementation of methods of formation of future teachers’ pedagogical culture by means of spiritual music in the educational process of pedagogical universities, have been also presented in the article.

  17. Experimental investigation of thermal limits in parallel plate configuration for the future material testing reactor (JHR)

    International Nuclear Information System (INIS)

    Brigitte Noel

    2005-01-01

    Full text of publication follows: The design of the future material testing reactor, named Jules Horowitz Reactor and dedicated to technological irradiations, will allow very high performances. The JHR will be cooled and moderated by light water. The preliminary core of JHR consists of 46 assemblies, arranged in a triangular lattice inside a rectangular aluminium matrix. It is boarded on two sides by a beryllium reflector. The other two sides are left free in order to introduce mobile irradiation devices. The JHR assembly would be composed of 3 x 6 cylindrical fuel plates maintained by 3 stiffeners. The external diameter of the assembly is close to 8 cm with a 600 mm heated length, coolant channels having a 1.8 mm gap width. The JHR core must be designed to accommodate high power densities using a high coolant mass flux and sub-cooling level at moderate pressure. The JHR core configuration with multi-channels is subject to a potential excursive instability, called flow redistribution, and is distinguished from a true critical heat flux which would occur at a fixed channel flow rate. At thermal-hydraulic conditions applicable to the JHR, the availability of experimental data for both flow redistribution and CHF is very limited. Consequently, a thermal-hydraulic test facility (SULTAN-RJH) was designed and built in CEA-Grenoble to simulate a full-length coolant sub-channel representative of the JHR core, allowing determination of both thermal limits under relevant thermal hydraulics conditions. The SULTAN-RJH test section simulates a single sub-channel in the JHR core with a cross section corresponding to a mean span (∼50 mm) that has a full reactor length (600 mm), the same flow channel gap (1.5 mm) and Inconel plates of 1 mm thickness. The tests with light water flowing vertically upward will investigate a heat flux range of 0-7 MW/m 2 , velocity range of 0.6-18 m/s, exit pressure range of 0.2-1.0 MPa and inlet temperature range of 25-180 deg.

    2013-09-15

    This review examines the role that respiratory plasticity has in the maintenance of breathing stability during sleep in individuals with sleep apnea. The initial portion of the review considers the manner in which repetitive breathing events may be initiated in individuals with sleep apnea. Thereafter, the role that two forms of respiratory plasticity, progressive augmentation of the hypoxic ventilatory response and long-term facilitation of upper airway and respiratory muscle activity, might have in modifying breathing events in humans is examined. In this context, present knowledge regarding the initiation of respiratory plasticity in humans during wakefulness and sleep is addressed. Also, published findings which reveal that exposure to intermittent hypoxia promotes breathing instability, at least in part, because of progressive augmentation of the hypoxic ventilatory response and the absence of long-term facilitation, are considered. Next, future directions are presented and are focused on the manner in which forms of plasticity that stabilize breathing might be promoted while diminishing destabilizing forms, concurrently. These future directions will consider the potential role of circadian rhythms in the promotion of respiratory plasticity and the role of respiratory plasticity in enhancing established treatments for sleep apnea.

    Acts of terrorism are becoming increasingly common throughout the world. These events represent a significant public health concern given the associated health consequences. Although it is clear that terrorist attacks have mental and physical health sequelae, the exact nature and prevalence of these consequences are unclear. Epidemiological research can play an important role in better understanding the mental and physical impact of terrorist attacks. In this editorial, we highlight recent epidemiological research on these terrorism-related health outcomes. We also provide suggestions for how future studies can build on the existing literature and describe ways in which epidemiological methods can be harnessed to extend the current literature. Lastly, we offer recommendations on how to best prepare communities for the aftermath of terrorist attacks, highlighting secondary intervention and prevention strategies. Overall, multilevel strategies are needed to adequately cope with the growing rise of terrorist acts, and these strategies will have to be reassessed as the nature of terrorist attacks changes.

    Red blood cell (RBC) sensitization occurs in some women in response to exposure to paternally derived RBC antigens during pregnancy or to nonself antigens on transfused RBCs during their lifetime. Once sensitized, future pregnancies may be at risk for hemolytic disease of the fetus and newborn. Although great strides have been made over the past few decades in terms of identifying blood group antigens and in predicting fetal anemia through the use of noninvasive monitoring, many questions remain in terms of understanding RBC alloimmunization risk factors, preventative therapies, and treatment strategies. At the present time, there is room for improvement in these areas in both developed and developing countries. Evidence-based, universal guidelines describing recommended RBC antigen matching transfusion strategies for girls or women, before pregnancy or during intrauterine transfusions, would be welcomed. A better understanding of the mechanism(s) of action of Rh immunoglobulin, first introduced more than half of a century ago and one of the most successful immunoprophylaxis therapies in existence today, would also be a large step forward. For example, answers to questions of the role(s) that fetal RBC clearance, antigen masking, antigen modulation, and immune suppression play in the effectiveness of Rh immunoglobulin may help to guide the development of novel preventative therapies during pregnancy for immunization to RhD and non-RhD antigens. Furthermore, a better understanding of the importance of anti-RhD or other alloantibody glycosylation patterns may be beneficial not only in developing such novel immunoprophylaxis therapies but also in predicting the clinical significance of existing maternal alloantibodies. One other area of need includes the development of therapies beyond intrauterine transfusions to mitigate the dangers of maternal alloantibodies to developing fetuses. We challenge physicians, scientists, and funding agencies to prioritize studies of

    Parkinson's disease (PD) is a neurodegenerative disorder resulting from the loss of dopaminergic neurons of the substantia nigra as well as degeneration of motor and nonmotor basal ganglia circuitries. Typically known for classical motor deficits (tremor, rigidity, bradykinesia), early stages of the disease are associated with a large nonmotor component (depression, anxiety, apathy, etc.). Currently, there are no definitive biomarkers of PD, and the measurement of dopamine metabolites does not allow for detection of prodromal PD nor does it aid in long-term monitoring of disease progression. Given that PD is increasingly recognized as complex and heterogeneous, involving several neurotransmitters and proteins, it is of importance that we advance interdisciplinary studies to further our knowledge of the molecular and cellular pathways that are affected in PD. This approach will possibly yield useful biomarkers for early diagnosis and may assist in the development of disease-modifying therapies. Here, we discuss preanalytical factors associated with metabolomics studies, summarize current mass spectrometric methodologies used to evaluate the metabolic signature of PD, and provide future perspectives of the rapidly developing field of MS in the context of PD.

    The development of new fibrilar materials based on electrospinning (ES) technique has a notable history of nearly four centuries of discoveries and results. The eletrospinning manufacturing is one of the most widely reported methods for nanofiber (NF) manufacturing, providing security, high quality and productivity. In spite of the first patent about electrospinning has been applied in April 5(th), 1900 by John Francis Cooley, a historical perspective (since 1600s) about this amazing discovery represents an important step for future applications. Nanofibers have been considered one of the top interesting fundamental study objects for academicians, and greatest intriguing business materials for modern industry. As a consequence, lucrative organizations and companies have explored the relevance of nanofibers. In this paper, the quantity of published manuscripts and patent inventions is presented and the correlation of research activities to the production of new electrospinning materials is shown. China and the United States have been leading in electrospinning and nanofibers development. The company triumph is mostly dependent on applications improvement relevant for broader business society. A dramatic rise of interest in nanofibers produced by electrospinning technique has been confirmed due to the publication data, author's affiliation, keywords, and essential characterization procedures. Is has been shown that the number of publications on electrospinning and nanofibers researches from academic institutions is higher than industrial laboratories. More than 1,891 patents using the term "electrospinning" and 2,960 with the term "nanofibers" according to the European Patent Office at title or abstract have been filed around the world up to 2013. These numbers just continue to increase along with worldwide ES-related sales. Curiously, for the same period 11,973 electrospinning documents and 18,679 nanofibers-related (mainly manuscripts) were published considering

    The functional levels of biological cells or organisms can be separated into the genome, transcriptome, proteome and metabolome. Of these the metabolome offers specific advantages to the investigation of the phenotype of biological systems. The investigation of the metabolome (metabolomics) has only recently appeared as a mainstream scientific discipline and is currently developing rapidly for the study of microbial, plant and mammalian metabolomes. The metabolome pipeline or workflow encompasses the processes of sample collection and preparation, collection of analytical data, raw data pre-processing, data analysis and data storage. Of these processes the collection of analytical data will be discussed in this review with specific interest shown in the application of mass spectrometry in the metabolomics pipeline. The current developments in mass spectrometry platforms (GC–MS, LC–MS, DIMS and imaging MS) and applications of specific interest will be highlighted. The current limitations of these platforms and applications will be discussed with areas requiring further development also highlighted. These include the detectable coverage of the metabolome, the identification of metabolites and the process of converting raw data to biological knowledge. (review article)

    Full Text Available Our main research topic is the analysis of leading companies in the Hungarian meat processing industry in terms of liquidity criteria. We examine this scientific subject by application of financial indicators and several important bankruptcy forecasting models. In our thesis the emphasis is placed on the presentation and evaluation of business failure models. The topicality of the research subject is rooted in the economic crisis and recession, which made solvency a key issue. Maintaining the competitive position in the market and the ability to stay in competition depend on the capability to generate an appropriate level of net operative cash flow. The most important research questions are the following. Which financial methods can be used to predict and estimate the situation when a company is facing bankruptcy? Do bankruptcy forecasting models provide accurate forecasts and what conclusions can be drawn based on these results? In our study we present the actual economic situation and the main problems of the sector, select the sample companies, calculate and compare the applied financial ratios and the most relevant bankruptcy forecasting models. On the basis of annual reports concerning 2010-2013 interval we investigate the financial position of leading pork processing companies. We make a comprehensive and comparative analysis concerning capital structure, liquidity, and profitability; consequently identify risky processes and companies having high probability of insolvency. Finally, we demonstrate and evaluate the results of three traditional bankruptcy forecasting models (Altman, Springate, and Fulmer and four modern models (DA, LR, industrial DA and industrial LR.

  15. Investigating ideomotor cognition with motorvisual priming paradigms: Key findings, methodological challenges, and future directions

    Directory of Open Access Journals (Sweden)

    Roland eThomaschke

    2012-11-01

    Full Text Available Ideomotor theory claims that perceptual representations of action effects are functionally involved in the planning of actions. Strong evidence for this claim comes from a phenomenon called motorvisual priming. Motorvisual priming refers to the finding that action planning directly affects perception, and that the effects are selective for stimuli that share features with the planned action. Motorvisual priming studies have provided detailed insights into the processing of perceptual representations in action planning. One important finding is that such representations in action planning have a categorical format, whereas metric representations are not anticipated in planning. Further essential findings regard the processing mechanisms and the time course of ideomotor cognition. Perceptual representations of action effects are first activated by action planning and then bound into a compound representation of the action plan. This compound representation is stabilized throughout the course of the action by the shielding of all involved representations from other cognitive processes. Despite a rapid growth in the number of motorvisual priming studies in the current literature, there are still many aspects of ideomotor cognition which have not yet been investigated. These aspects include the scope of ideomotor processing with regard to action types and stimulus types, as well as the exact nature of the binding and shielding mechanisms involved.

    Full Text Available The unprecedented development of criminality at the social and economical levels, the tendency toglobalize some categories of crimes, of maximum gravity, as terrorism, armament traffic, drug traffic orhuman traffic, have determined the world states to undertake specific measures to prevent, combat and finallyreduce it. The first and most important measure taken by the Europe’s Council, regarding the intensificationof judicial cooperation in criminal matters was the adoption of the European Convention on extradition, inParis on 13 December 1957, completed by the two Additional Protocols in Strasbourg, on 15 October 1975and 17 March 1978. In this context, the release of the Council’s Framework Decision on 13 June 2002 on theEuropean arrest warrant and the procedures of delivery among the member states (2002/584/JAI representeda natural decision, with the purpose of contributing at ensuring a free, secure and just European space. TheEuropean arrest warrant is a judicial decision through which a competent judicial authority of a EuropeanUnion member state solicits the arrest and delivery by another member state, in order to proceed to theprosecution, trial or execution of a penalty or safety measure that is privative of freedom.

  19. Diagnosing true virtue? Remote scenarios, warranted virtue attributions, and virtuous medical practice.

    Science.gov (United States)

    Oakley, Justin

    2016-02-01

    Immanuel Kant argues in the Foundations that remote scenarios are diagnostic of genuine virtue. When agents commonly thought to have a particular virtue fail to exhibit that virtue in an extreme situation, he argues, they do not truly have the virtue at all, and our propensities to fail in such ways indicate that true virtue might never have existed. Kant's suggestion that failure to show, say, courage in extraordinary circumstances necessarily silences one's claim to have genuine courage seems to rely on an implausibly demanding standard for warranted virtue attributions. In contrast to this approach, some philosophers-such as Robert Adams and John Doris-have argued for probabilistic accounts of warranted virtue attributions. But despite the initial plausibility of such accounts, I argue that a sole reliance on probabilistic approaches is inadequate, as they are insufficiently sensitive to considerations of credit and fault, which emerge when agents have developed various insurance strategies and protective capacities against their responding poorly to particular eventualities. I also argue that medical graduates should develop the sorts of virtuous dispositions necessary to protect patient welfare against various countervailing influences (even where such influences might be encountered only rarely), and that repeated failures to uphold the proper goals of medicine in emergency scenarios might indeed be diagnostic of whether an individual practitioner does have the relevant medical virtue. In closing, I consider the dispositions involved in friendship. I seek to develop a principled way of determining when remote scenarios can be illuminating of genuine friendship and genuine virtue.

    Sophia M. Brink

    2017-07-01

    Full Text Available Background: Trusts have long been used as an estate planning mechanism, including the avoidance of estate duty and donations tax. In the 2016 National Budget the Minister of Finance indicated that Government was proposing several legislative measures during 2016/2017 to prevent individuals from using a trust to avoid estate duty (and donations tax to a certain extent. Unexpectedly, the 2016 draft Taxation Laws Amendment Bill and the final Amendment Bill did not give effect to any of these proposals, but introduced other less drastic measures to control the abuse of trusts for tax purposes, albeit with the same stated purpose. Aim: The main aim of the study was to clarify the reform proposals (albeit unclear and consequently based on certain assumptions and to compare the reform proposals with the final amendments. This comparison will shed some light on the fairness and appropriateness of the final amendments and, more importantly, on the possibility that the reform proposals published by National Treasury in February 2016 not included in the final amendments will be enacted in the future. This investigation will assist tax practitioners and taxpayers in effective tax and estate planning, given that the reform proposals and final amendments have a possible impact on the future of discretionary trusts in South Africa. Setting: This article examines existing literature in a South African income tax environment. Methods: In order to meet this objective a qualitative approach based on a literature study of pure theoretical aspects was used. Results and conclusion: It was found that should the reform proposals become law, many trusts would become ineffective from a tax-planning perspective and these changes might erode other benefits trusts offer, jeopardising the future of discretionary trusts in South Africa.

  1. Placing the pieces: Reconstructing the original property mosaic in a warrant and patent watershed

    Recent research shows that land use history is an important determinant of current ecosystem function. In the United States, characterization of land use change following European settlement requires reconstruction of the original property mosaic. However, this task is difficult in unsystematically surveyed areas east of the Appalachian Mountains. The Gwynns Falls watershed (Baltimore, MD) was originally surveyed in the 1600-1700s under a system of warrants and patents (commonly known as 'metes and bounds'). A method for the reconstruction and mapping of warrant and patent properties is presented and used to map the original property mosaic in the Gwynns Falls watershed. Using the mapped mosaic, the persistence of properties and property lines in the current Gwynns Falls landscape is considered. The results of this research indicate that as in agricultural areas, the original property lines in the Gwynns Falls watershed are persistent. At the same time, the results suggest that the property mosaic in heavily urbanized/suburbanized areas is generally 'reset.' Further, trends in surveying technique, parcel size, and settlement patterns cause property line density and property shape complexity to increase in the less urbanized upper watershed. The persistence of original patterns may be damping expression of heterogeneity gradients in this urban landscape. This spatial pattern of complexity in the original mosaic is directly opposite of hypothesized patterns of landscape heterogeneity arising from urbanization. The technique reported here and the resulting observations are important for landscape pattern studies in areas settled under unsystematic survey systems, especially the heavily urbanized areas of the eastern United States. ?? 2004 Kluwer Academic Publishers.

    The Renewable Electricity Futures Study (RE Futures) provides an analysis of the grid integration opportunities, challenges, and implications of high levels of renewable electricity generation for the U.S. electric system. The study is not a market or policy assessment. Rather, RE Futures examines renewable energy resources and many technical issues related to the operability of the U.S. electricity grid, and provides initial answers to important questions about the integration of high penetrations of renewable electricity technologies from a national perspective. RE Futures results indicate that a future U.S. electricity system that is largely powered by renewable sources is possible and that further work is warranted to investigate this clean generation pathway.

    Breast cancer tumor markers are used by some clinicians to screen for disease recurrence risk. Since there is limited evidence of benefit, additional research may be warranted. To assess the potential value of a randomized clinical trial of breast tumor marker testing in routine follow-up of high-risk, stage II-III breast cancer survivors. We developed a decision-analytic model of tumor marker testing plus standard surveillance every 3-6 months for 5 years. The expected value of sample information was calculated using probabilistic simulations and was a function of: the probability of selecting the optimal monitoring strategy with current versus future information; the impact of choosing the nonoptimal strategy; and the size of the population affected. The value of information for a randomized clinical trial involving 9000 women was US$214 million compared with a cost of US$30-60 million to conduct such a trial. The probability of making an alternate, nonoptimal decision and choosing testing versus no testing was 32% with current versus future information from the trial. The impact of a nonoptimal decision was US$2150 and size of population impacted over 10 years was 308,000. The value of improved information on overall survival was US$105 million, quality of life US$37 million and test performance US$71 million. Conducting a randomized clinical trial of breast cancer tumor markers appears to offer a good societal return on investment. Retrospective analyses to assess test performance and evaluation of patient quality of life using tumor markers may also offer valuable areas of research. However, alternative investments may offer even better returns in investments and, as such, the trial concept deserves further study as part of an overall research-portfolio evaluation.

  4. Carotid sinus hypersensitivity: Entity warrants a caution in the critical care unit

    Directory of Open Access Journals (Sweden)

    Sugata Dasgupta

    2016-01-01

    Full Text Available Carotid sinus hypersensitivity (CSH syndrome is an entity caused by an overreaction of the carotid sinus baroreceptors to stimulation. Three subtypes of CSH syndrome are recognized according to the response to carotid sinus massage (CSM: Predominantly cardioinhibitory, predominantly vasodepressor and a mixed subtype. We report here the case of a middle-aged female patient admitted in our critical care unit with respiratory failure requiring mechanical ventilation. There were episodes of severe bradycardia whenever her head was rotated to any side, relieved on neutralizing head position and administering intravenous atropine. CSM revealed she had predominantly cardioinhibitory type of CSH syndrome. A cardioinhibitory form of hypersensitive carotid sinus reflex, which is idiopathic in causation, probably explains the severe bradycardia on head rotation seen in our patient. A heightened awareness of this syndrome is necessary for timely diagnosis and management. CSH syndrome results from an overreaction of the carotid sinus baroreceptors to stimulation, manifesting commonly as bradycardia, hypotension and syncope. It is an entity, which warrants caution during routine critical care practices.

    One of the complicating factors of the future robotic and human lunar landing missions is the influence of the dust. Meteorites bombardment has accompanied by shock-explosive phenomena, disintegration and mix of the lunar soil in depth and on area simultaneously. As a consequence, the lunar soil has undergone melting, physical and chemical transformations. Recently we have the some reemergence for interest of Moon investigation. The prospects in current century declare USA, China, India, and European Union. In Russia also prepare two missions: Luna-Glob and Luna-Resource. Not last part of investigation of Moon surface is reviewing the dust condition near the ground of landers. Studying the properties of lunar dust is important both for scientific purposes to investigation the lunar exosphere component and for the technical safety of lunar robotic and manned missions. The absence of an atmosphere on the Moon's surface is leading to greater compaction and sintering. Properties of regolith and dust particles (density, temperature, composition, etc.) as well as near-surface lunar exosphere depend on solar activity, lunar local time and position of the Moon relative to the Earth's magneto tail. Upper layers of regolith are an insulator, which is charging as a result of solar UV radiation and the constant bombardment of charged particles, creates a charge distribution on the surface of the moon: positive on the illuminated side and negative on the night side. Charge distribution depends on the local lunar time, latitude and the electrical properties of the regolith (the presence of water in the regolith can influence the local distribution of charge). On the day side of Moon near surface layer there exists possibility formation dusty plasma system. Altitude of levitation is depending from size of dust particle and Moon latitude. The distribution of dust particles by size and altitude has estimated with taking into account photoelectrons, electrons and ions of solar wind

    A total of eight commercial spaceflight participants have launched to the International Space Station (ISS) on Soyuz vehicles. Based on an older mean age compared to career astronauts and an increased prevalence of medical conditions, spaceflight participants have provided the opportunity to learn about the effect of space travel on crewmembers with medical problems. The 12-d Soyuz TMA-13/12 ISS flight of spaceflight participant Richard Garriott included medical factors that required preflight intervention, risk mitigation strategies, and provided the opportunity for medical study on-orbit. Equally important, Mr. Garriott conducted extensive medical, scientific, and educational payload operations during the flight. These included 7 medical experiments and a total of 15 scientific projects such as protein crystal growth, Earth observations/photography, educational projects with schools, and amateur radio. The medical studies included the effect of microgravity on immune function, sleep, bone loss, corneal refractive surgery, low back pain, motion perception, and intraocular pressure. The overall mission success resulted from non-bureaucratic agility in mission planning, cooperation with investigators from NASA, ISS, International Partners, and the Korean Aerospace Research Institute, in-flight support and leadership from a team with spaceflight and Capcom experience, and overall mission support from the ISS program. This article focuses on science opportunities that suborbital and orbital spaceflight participant flights offer and suggests that the science program on Richard Garriott's flight be considered a model for future orbital and suborbital missions. The medical challenges are presented in a companion article.

  7. The valuation of equity warrants under the fractional Vasicek process of the short-term interest rate

    2014-01-01

    Motivated by the empirical evidence of long range dependence in short-term interest rates and considering the long maturities of equity warrants, we propose the fractional Vasicek model to describe the dynamics of the short rate in the pricing environment of equity warrants. Using the partial differential equation approach, we present a valuation model for equity warrants under the assumption that the short rate follows the fractional Vasicek process. After identifying the pricing model for equity warrants, we provide the parameter estimation procedure for the proposed pricing model. Since obtaining the values of equity warrants from the proposed model needs to solve a nonlinear equation, we employ a hybrid intelligent algorithm to get around this optimization problem. Furthermore, to illustrate the practicality of our proposed model, we conduct an empirical study to ascertain the performance of our proposed model using the data from China’s warrant market and the China Foreign Exchange Trade System. The comparison of traditional models (such as the Black-Scholes model, the Noreen-Wolfson model, the Lauterbach-Schultz model, and the Ukhov model) with our proposed model is also presented. The empirical results show that the mean absolute percentage error of our pricing model is 10.30%. By contrast, the Black-Scholes model, the Noreen-Wolfson model, the Lauterbach-Schultz model, and the Ukhov model applied to the same warrant produce mean absolute errors of 35.26%, 37.67%, 33.40%, 32.81%, respectively. Thus the long memory property in stochastic interest rates cannot be ignored in determining the valuation of equity warrants.

  10. Future versus present: time perspective and pupillary response in a relatedness judgment task investigating temporal event knowledge.

    2013-02-01

    Mental representations of events contain many components such as typical agents, instruments, objects as well as a temporal dimension that is directed towards the future. While the role of temporal orientation (chronological, reverse) in event knowledge has been demonstrated by numerous studies, little is known about the influence of time perspective (present or future) as source of individual differences affecting event knowledge. The present study combined behavioral data with task-evoked pupil dilation to examine the impact of time perspective on cognitive resource allocation. In a relatedness judgment task, everyday events like raining were paired with an object feature like wet. Chronological items were processed more easily than reverse items regardless of time perspective. When more automatic processes were applied, greater scores on future time perspective were associated with lower error rates for chronological items. This suggests that a match between a strong focus on future consequences and items with a temporal orientation directed toward the future serves to enhance responding accuracy. Indexed by pupillary data, future-oriented participants invested more cognitive resources while outperforming present-oriented participants in reaction times across all conditions. This result was supported by a principal component analysis on the pupil data, which demonstrated the same impact of time perspective on the factor associated with more general aspects of cognitive effort. These findings suggest that future time perspective may be linked to a more general cognitive performance characteristic that improves overall task performance. Copyright © 2012 Elsevier B.V.

    questionnaire to assess COPD symptoms and OSA risk, comorbidities, and performance of daily activities. Data from COPD cohorts with and without risk of OSA were analyzed and compared. Results: Of 6,600 interviews completed, 404 subjects fit the epidemiological case definition of COPD – an overall prevalence of 6.1% in this national sample. Data on OSA risk were available for 292 of this COPD cohort, of whom 29.5% were at risk of OSA. Compared to those without risk of OSA, those with risk of OSA were significantly more likely to have hypertension or cardiovascular disease and diabetes, had significantly higher body mass index and COPD Assessment Test scores, and reported impaired work performance and leisure activities. Conclusion: Among adults in Taiwan who fulfill epidemiologic criteria for COPD, 29.5% have coexisting risk of OSA. Comorbid hypertension or cardiovascular disease and diabetes are common and significantly more prevalent among the COPD population at risk of OSA than those who are not. OSA screening is warranted in patients with COPD with those risk factors that are more prevalent in COPD with risk of OSA than without, to target early interventions to reduce adverse cardiovascular sequelae from overlap syndrome. Keywords: cardiovascular risk, COPD, coexistent, obstructive sleep apnea, OSA, overlap syndrome

    Climate change is a significant future driver of change in coastal social-ecological systems. Our knowledge of impacts, adaptation options, and possible outcomes for marine environments and coastal industries is expanding, but remains limited and uncertain. Alternative scenarios are a way to explore potential futures under a range of conditions. We developed four alternative future scenarios for the Great Barrier Reef and its fishing and tourism industries positing moderate and more extreme (2-3 °C above pre-industrial temperatures) warming for 2050 and contrasting 'limited' and 'ideal' ecological and social adaptation. We presented these scenarios to representatives of key stakeholder groups to assess the perceived viability of different social adaptation options to deliver desirable outcomes under varied contexts.

  14. West Nile Virus: High Transmission Rate in North-Western European Mosquitoes Indicates Its Epidemic Potential and Warrants Increased Surveillance.

    Jelke J Fros

    Full Text Available West Nile virus (WNV is a highly pathogenic flavivirus transmitted by Culex spp. mosquitoes. In North America (NA, lineage 1 WNV caused the largest outbreak of neuroinvasive disease to date, while a novel pathogenic lineage 2 strain circulates in southern Europe. To estimate WNV lineage 2 epidemic potential it is paramount to know if mosquitoes from currently WNV-free areas can support further spread of this epidemic.We assessed WNV vector competence of Culex pipiens mosquitoes originating from north-western Europe (NWE in direct comparison with those from NA. We exposed mosquitoes to infectious blood meals of lineage 1 or 2 WNV and determined the infection and transmission rates. We explored reasons for vector competence differences by comparing intrathoracic injection versus blood meal infection, and we investigated the influence of temperature. We found that NWE mosquitoes are highly competent for both WNV lineages, with transmission rates up to 25%. Compared to NA mosquitoes, transmission rates for lineage 2 WNV were significantly elevated in NWE mosquitoes due to better virus dissemination from the midgut and a shorter extrinsic incubation time. WNV infection rates further increased with temperature increase.Our study provides experimental evidence to indicate markedly different risk levels between both continents for lineage 2 WNV transmission and suggests a degree of genotype-genotype specificity in the interaction between virus and vector. Our experiments with varying temperatures explain the current localized WNV activity in southern Europe, yet imply further epidemic spread throughout NWE during periods with favourable climatic conditions. This emphasizes the need for intensified surveillance of virus activity in current WNV disease-free regions and warrants increased awareness in clinics throughout Europe.

    Male infertility constitutes 30-40% of all infertility cases. Some studies have shown a continuous decline in semen quality since the beginning of the 20th century. One postulated contributing factor is radio frequency electromagnetic radiation emitted from cell phones. This study investigates an association between characteristics of cell phone usage and semen quality. Questionnaires accessing demographic data and characteristics of cell phone usage were completed by 106 men referred for semen analysis. Results were analysed according to WHO 2010 criteria. Talking for ≥1 h/day and during device charging were associated with higher rates of abnormal semen concentration (60.9% versus 35.7%, P cell phone usage may bear adverse effects on sperm concentration. Investigation using large-scale studies is thus needed. Copyright © 2015 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

    2015-07-01

    Sport talent identification and development (TI and TD) in youth continues to attract strong interest among coaches, sport scientists and sport administrators. TI for sport in youth with the anticipation of future elite level sport achievement is both an art and a science, and is strongly influenced by within athlete and extraneous-to-athlete factors (ecosystem of support or the lack of). The returns from investment on current TI and TD models of sport in youth are subpar in that few continue in the sport to achieve podium positions at the elite sport level in adulthood. Why, where and how one succeeds in sport, and what that success means to the athlete and stakeholders are dependent on the culture and context of the country. We advocate harnessing the power of sport to help in youth development, to be holistic in its nurturance, to allow for individual idiosyncratic expressions of the athletes, to provide for talent transfer across sport, and to facilitate key stakeholders to 'join' hands to work for the common interest and understanding for as many youth and adults so as to provide them with opportunities through support and coaching to compete at the different levels of competition in sport. Governments, policy makers and administrators of sport must decide, within their specific circumstances, if TI and TD in sport in youth is serving a meaningful purpose and is a viable return on investment; in short, is it mission possible or is it… a quest for the Holy Grail for a podium finish in elite level sport competition?

    Recently, temperature in urban areas continue to rise as an effect of climate change and urbanization. Specifically, Asian megacities are projected to expand rapidly resulting to serious in the future atmospheric environment. Thus, detailed analysis of urban meteorology for Asian megacities is needed to prescribe optimum against these negative climate modifications. A building-resolving large eddy simulation (LES) coupled with an energy balance model is conducted for a highly urbanized district in central Jakarta on typical daytime hours. Five cases were considered; case 1 utilizes present urban scenario and four cases representing different urban configurations in 2050. The future configurations were based on representative concentration pathways (RCP) and shared socio-economic pathways (SSP). Building height maps and land use maps of simulation domains are shown in the attached figure (top). Case 1 3 focuses on the difference of future scenarios. Case 1 represents current climatic and urban conditions, case 2 and 3 was an idealized future represented by RCP2.6/SSP1 and RCP8.5/SSP3, respectively. More complex urban morphology was applied in case 4, vegetation and building area were changed in case 5. Meteorological inputs and anthropogenic heat emission (AHE) were calculated using Weather Research and Forecasting (WRF) model (Varquez et al [2017]). Sensible and latent heat flux from surfaces were calculated using an energy balance model (Ashie et al [2011]), with considers multi-reflection, evapotranspiration and evaporation. The results of energy balance model (shown in the middle line of figure), in addition to WRF outputs, were used as input into the PArallelized LES Model (PALM) (Raasch et al [2001]). From standard new effective temperature (SET*) which included the effects of temperature, wind speed, humidity and radiation, thermal comfort in urban area was evaluated. SET* contours at 1 m height are shown in the bottom line of the figure. Extreme climate

    2018-04-01

    Episodic future thinking (EFT), an intervention involving mental simulation of future events, has been shown to reduce both delay discounting and cigarette self-administration. In the present study, we extended these findings by showing that EFT in a web-based sample of smokers reduces delay discounting and intensity of demand for cigarettes (ad libitum consumption) in a hypothetical purchase task. No effect was observed on elasticity of demand (sensitivity to price) or cigarette craving. We also explored whether demand characteristics (specifically, the "good-subject" effect) might be responsible for observed effects. EFT participants were significantly better able than control participants to discern the experimental hypothesis. However, EFT participants were not better than controls at identifying whether they had been assigned to the experimental group and, likewise, showed no differences in attitudes about the experiment and experimenter. Importantly, effects of EFT on delay discounting and demand remained significant even when controlling for measures of demand characteristics, indicating that EFT's effects are independent of participants' perceptions about the experiment.

  3. Peculiarities of the Enforcement of the European Arrest Warrant in the Case of an Illegal Liberty Deprivation

    2010-06-01

    Full Text Available The illegal deprivation of liberty is, under the current context, one of the most serious offenses, being treated differently in the European Union. The need to prevent and combat this violation, it has led the European legislator to include it under different names in the European legislative act that governs the institution of the European arrest warrant. In this context, the European arrest warrant is the most important form of judicial cooperation in penal matters between the Member States of the EU, which is based on mutualrecognition of criminal judgments. The research conducted on how it is regulated the enforcement of the European arrest warrant in the case of illegal liberty deprivation in the European legislative act (the Framework Decision 2002/584/JHA leads to the conclusion that the legislature failed to mention the violation in question in the group of the violation for which it was not necessary the inspection of the double incrimination, but, still, including the offenses as kidnapping, illegal restraint and hostage-taking. Even if theRomanian legislator included this violation in the above mentioned group, this situation is not solved, because it will cause some problems in the request by the Romanian judicial authorities of the enforcement of such warrant. Another criticized issue, observed not only in the European legislative act, but also in the internal law, is related to the lack of stipulations, which can lead to the possibility of issuing and executing a European arrest warrant and for the execution of educational measures for illegal deprivation of liberty and also others. Also, in order to increase the effectiveness of the execution of a European arrest warrant, we consider that it should be granted executive powers of all courts of Romania. The originality of the work consists of the critical observations and the lege ferenda proposal which covers both the European legislativeact and the Romanian Law. At the same time

    2016-01-01

    The amazing accuracy of migratory orientation performance across the animal kingdom is facilitated by the use of magnetic and celestial compass systems that provide individuals with both directional and positional information. Quantitative genetics analyses in several animal systems suggests that migratory orientation has a strong genetic component. Nevertheless, the exact identity of genes controlling orientation remains largely unknown, making it difficult to obtain an accurate understanding of this fascinating behavior on the molecular level. Here, we provide an overview of molecular genetic techniques employed thus far, highlight the pros and cons of various approaches, generalize results from species-specific studies whenever possible, and evaluate how far the field has come since early quantitative genetics studies. We emphasize the importance of examining different levels of molecular control, and outline how future studies can take advantage of high-resolution tracking and sequencing techniques to characterize the genomic architecture of migratory orientation.

    2010-01-01

    The professional community of nephrologists is going through a phase of ''rethinking'' the discipline that sees the role of nephrologists in an uncertain position between inpatient and outpatient care. A comparison of opinions within the community is necessary to understand what could be the future position of nephrology in the Italian healthcare system. In June 2009 a questionnaire was distributed among the members of the Italian Nephrology Society (SIN) to collect (i) their professional biographies and (ii) their opinion on the state of the art of nephrology, (iii) the working context in which they operate, (iv) the likely sources of change, and (v) the prospects for the development of the field. In October 2009 the respondents were 506, a sufficiently representative sample of the national population of nephrologists. One of the main findings was a lack of consensus about the clinical practice for the treatment of CKD. In particular, there was no general agreement about the stage of CKD at which the patient should enter the exclusive care of the nephrologist. Opinions were less divergent on (i) departmentalization phenomena, (ii) the outsourcing of dialysis services, and (iii) the future prospects of the specialty. In order to pursue common goals for the development of the discipline, the internal relations of the professional community should be strengthened both in terms of sharing clinical experience and defining the roles of clinicians within the community. The involvement of young nephrologists in the definition of strategies for the positioning of nephrology in the Italian healthcare system might also be considered a priority.

  6. Comparative investigations of manual action representations: evidence that chimpanzees represent the costs of potential future actions involving tools.

    2012-01-12

    The ability to adjust one's ongoing actions in the anticipation of forthcoming task demands is considered as strong evidence for the existence of internal action representations. Studies of action selection in tool use reveal that the behaviours that we choose in the present moment differ depending on what we intend to do next. Further, they point to a specialized role for mechanisms within the human cerebellum and dominant left cerebral hemisphere in representing the likely sensory costs of intended future actions. Recently, the question of whether similar mechanisms exist in other primates has received growing, but still limited, attention. Here, we present data that bear on this issue from a species that is a natural user of tools, our nearest living relative, the chimpanzee. In experiment 1, a subset of chimpanzees showed a non-significant tendency for their grip preferences to be affected by anticipation of the demands associated with bringing a tool's baited end to their mouths. In experiment 2, chimpanzees' initial grip preferences were consistently affected by anticipation of the forthcoming movements in a task that involves using a tool to extract a food reward. The partial discrepancy between the results of these two studies is attributed to the ability to accurately represent differences between the motor costs associated with executing the two response alternatives available within each task. These findings suggest that chimpanzees are capable of accurately representing the costs of intended future actions, and using those predictions to select movements in the present even in the context of externally directed tool use.

    1997-01-01

    Issues regarding future development by oil and gas companies in Canada's Arctic and the Beaufort Sea were discussed. It was suggested in the Berger report that Northern development should be under the control of the people whose lives and economy are being changed. Aboriginal people are now much more sophisticated politically, and have a better understanding of what is involved. Most of them would like the financial benefits from development, but the development would have to be on their terms. Most people involved with Arctic oil exploration feel that there is enough oil in the Arctic to warrant production. (Reserves in the Beaufort Sea are estimated at two billion barrels of good quality oil). If development were to continue, there exist two methods of transportation to move the oil to market. Gulf, Imperial Oil and Panarctic favour the use of pipelines, whereas Dome Petroleum Ltd. favours the use of ice-breaking tankers. In each case the favored option seems to depend upon the location of the company's leases, the capital and operating costs, and the potential environmental impacts. Undoubtedly, any future development will be guided by the scientific information and technical expertise of oil industry pioneers of the 1960s and the 1970s, and the wisdom gained from the experiences of the many participants whose views and insights are recorded in this book

    Final comments and conclusions: • Modern plants, should have performed better under Fukushima type event. • In future fast reactor systems significantly higher active and passive safety features are installed, which should cope with events like Fukushima. • One important lesson: put a focus on rare initiators, accident routes and consequences that are neither expected nor have been observed, events that are categorized under ‘black swans’. • Importance of severe accident research demonstrated - both analytically and experimentally for assessing and interpreting accident scenarios and developments. Precondition for developing preventive & mitigative safety measures. Passive safety measures are in the focus of advanced design options and must work under conditions of multiple loads and aggravating events. • Fast reactor systems behavior as the SFR under severe accident conditions: – In fast spectrum systems as the SFR the core is not in its neutronically most reactive configuration and SFRs may be loaded with MAs for waste management; – Recriticalities have a high probability because of the higher enrichment levels; – Short time scales have to be envisioned for core melt-down; – Decay heat levels might be significantly higher, if MA bearing fuel is involved. • Improve design by measures for prevention and/or mitigation of recriticalities; – High reliability of simulations required for proof; • Assessment of fuel relocated on peripheral structures; • Preventive/mitigating measures should not replace containment measures

  12. Investigating the Impact of Past and Future CO2 Emissions on the Distribution of Radiocarbon in the Ocean

    Khatiwala, S.; Payne, S.; Graven, H. D.; Heimbach, P.

    2015-12-01

    The ocean is a significant sink for carbon dioxide from fossil fuel burning, absorbing roughly a third of human CO2 emitted over the industrial period. This has implications not only for climate but also for the chemical and isotopic composition of the ocean. Human activities have increased the ocean radiocarbon content through nuclear bomb tests in the 1950s-60s, which released a large amount of radiocarbon (14C) into the atmosphere, but fossil fuel emissions are decreasing the radiocarbon content through the release of 14C-depleted CO2. Here, we use the ECCO-v4 ocean state estimate to examine the changing nature of the air-sea flux of radiocarbon and its spatial distribution in the ocean in response to past and future CO2 emissions, the latter taken from the the Representative Concentration Pathway (RCP) database used in IPCC simulations. In line with previous studies we find that the large air-sea gradient of 14C induced by nuclear bomb testing led to rapid accumulation of radiocarbon in the surface ocean. Surface fluxes of 14C have considerably weakened over the past several decades and in some areas 14C is being returned to the atmosphere. As fossil fuel emissions continue to reduce the atmospheric 14C/C ratio (Δ14C), in most RCP scenarios the total ocean 14C inventory starts decreasing by 2030. With strong emissions, the Δ14C of surface waters is driven to increasingly negative values and in RCP 8.5 by 2100 much of the surface ocean has apparent radiocarbon ages in excess of 2000 years, with subtropical gyres more depleted in 14C than the Southern Ocean. Surface waters become significantly more negative in Δ14C than underlying waters. As a result, turning conventional tracer oceanography on its head, recently ventilated waters are characterized by more negative Δ14C values. Similar patterns can be expected for CFCs in the ocean as atmospheric concentrations decrease over the next several decades. Our results have a number of implications, notably for

    It has been argued that UK general practice specialist training should be extended to better prepare GPs for the challenges facing 21st-century health care. Evidence is needed to inform how this should occur. To investigate the experience of recently trained GPs undertaking a 1-year full-time fellowship programme designed to provide advanced skills training in urgent care, integrated care, leadership, and academic practice; and its impact on subsequent career development. Semi-structured interviews conducted longitudinally over 2 years augmented by observational data in the West Midlands, England. Participants were interviewed on at least three occasions: twice while undertaking the fellowship, and at least once post-completion. Participants' clinical and academic activities were observed. Data were analysed using a framework approach. Seven GPs participated in the pilot scheme. The fellowship was highly rated and felt to be balanced in terms of the opportunities for skill development, academic advancement, and confidence building. GPs experienced enhanced employability on completing the scheme, and at follow-up were working in a variety of primary care/urgent care interface clinical and leadership roles. Participants believed it was making general practice a more attractive career option for newly qualified doctors. The 1-year fellowship provides a defined framework for training GPs to work in an enhanced manner across organisational interfaces with the skills to support service improvement and integration. It appears to be well suited to preparing GPs for portfolio roles, but its wider applicability and impact on NHS service delivery needs further investigation. © British Journal of General Practice 2017.

    This study investigates the anticipated psychosocial impact of present web-based e-health services and future mobile health applications among older Swedes. Random sample's of Swedish citizens aged 55 years old and older were given a survey containing two different e-health scenarios which respondents rated according to their anticipated psychosocial impact by means of the PIADS instrument. Results consistently demonstrated the positive anticipation of psychosocial impacts for both scenarios. The future mobile health applications scored more positively than the present web-based e-health services. An increase in age correlated positively to lower impact scores. These findings indicate that from a psychosocial perspective, web-based e-health services and mobile health applications are likely to positively impact quality of life. This knowledge can be helpful when tailoring and implementing e-health services that are directed to older people.

  16. Neutronic investigations on the application of lithium aluminates in the tritium breeding blanket of future fusion reactors

    Mohsin, A.

    1981-02-01

    A survey is given about the state of development work at the blanket. It shows that present designs aim at a fusion reactor with low tritium inventory. This aim can be achieved with a solid blanket. In this paper this concept is described and the selection of appropriate materials for the solid blanket is discussed. The lithium aluminates turned out to be the most suitable materials. Comparing the different lithium aluminates the compounds Li 5 AlO 4 and LiAlO 2 proved to be the most favourable. The improvement of the breeding ratio when using lead as neutron multiplier was investigated. Employing, for example, a lead zone of 15 cm thickness in front of a 60 cm thick breeding zone, the tritium breeding ratio is raised to 1.65 for Li 5 Al 4 and to 1.48 for LiAlO 2 - The originally higher breeding ratio of the Li 5 AlO 4 in contrary to the LiAlO 2 is compensated hereby. By this LiAlO 2 becomes a very interesting material for a solid blanket since it furthermore exhibits a higher melting point and higher phase transition temperature. For experimental check of the nuclear data of this material and the computational techniques used, a test model was designed and built. This blanket model was used for measuring the space-dependent tritium production rate, which could be compared to corresponding computations. The assembly was made of a lead zone as neutron multiplier, LiAlO 2 as breeding material, and polyethylene as neutron reflector. (orig.) [de

    Cheng, Betty H. C.; Atlee, Joanne M.

    In this paper, we review current requirements engineering (RE) research and identify future research directions suggested by emerging software needs. First, we overview the state of the art in RE research. The research is considered with respect to technologies developed to address specific requirements tasks, such as elicitation, modeling, and analysis. Such a review enables us to identify mature areas of research, as well as areas that warrant further investigation. Next, we review several strategies for performing and extending RE research results, to help delineate the scope of future research directions. Finally, we highlight what we consider to be the “hot” current and future research topics, which aim to address RE needs for emerging systems of the future.

    This paper outlines current challenges facing healthcare providers and education providers in trying to ensure Allied Health Professionals (AHPs) are fit for practice, in a climate driven by financial constraints and service improvement directives from the Department of Health (DH). Research was undertaken in 2009 to investigate the current provision of Continuing Professional Development (CPD) in the southwest region of England. The purpose was to define exactly what problems existed with this provision, and to propose changes which could be implemented in order to ensure that the provision meets the needs of stakeholders in future years.

    In New Zealand, as in many other countries, housing in the private-rental sector is in worse condition than in the owner-occupier housing sector. New Zealand residential buildings have no inspection regime after original construction signoff. Laws and regulations mandating standards for existing residential housing are outdated and spread over a range of instruments. Policies to improve standards in existing housing have been notoriously difficult to implement. In this methods paper, we describe the development and implementation of a rental Warrant of Fitness (WoF) intended to address these problems. Dwellings must pass each of 29 criteria for habitability, insulation, heating, ventilation, safety, amenities, and basic structural soundness to reach the WoF minimum standard. The WoF’s development was based on two decades of research on the impact of housing quality on health and wellbeing, and strongly influenced by the UK Housing Health and Safety Rating System and US federal government housing standards. Criteria were field-tested across a range of dwelling types and sizes, cities, and climate zones. The implementation stage of our WoF research consists of a non-random controlled quasi-experimental study in which we work with two city-level local government councils to implement the rental WoF, recruiting adjoining council areas as controls, and measuring changes in health, economic, and social outcomes.

    An American option (or, warrant) is the right, but not the obligation, to purchase or sell an underlying equity at any time up to a predetermined expiration date for a predetermined amount. A perpetual American option differs from a plain American option in that it does not expire. In this study, we solve the optimal stopping problem of a perpetual American option (both call and put) in discrete time using linear programming duality. Under the assumption that the underlying stock price follows a discrete time and discrete state Markov process, namely a geometric random walk, we formulate the pricing problem as an infinite dimensional linear programming (LP) problem using the excessive-majorant property of the value function. This formulation allows us to solve complementary slackness conditions in closed-form, revealing an optimal stopping strategy which highlights the set of stock-prices where the option should be exercised. The analysis for the call option reveals that such a critical value exists only in some cases, depending on a combination of state-transition probabilities and the economic discount factor (i.e., the prevailing interest rate) whereas it ceases to be an issue for the put.

  3. 'Thinking ill of others without sufficient warrant?' Transcending the accuracy-inaccuracy dualism in prejudice and stereotyping research.

    2017-03-01

    Research on prejudice seeks to understand and transform inaccurate beliefs about others. Indeed, historically such research has offered a cautionary tale of the biased nature of human cognition. Recently, however, this view has been challenged by work defending the essential rationality of intergroup perception, a theme captured controversially in Jussim and colleagues' (2009) research on the 'unbearable accuracy of stereotyping'. The present paper argues that in its own terms the 'rationalist turn' in socio-cognitive research on stereotyping presents an important challenge to the prejudice tradition, raising troubling questions about its conceptual and empirical foundations. However, it also argues for the necessity of transcending those terms. By focusing on the correspondence between individual beliefs and the supposedly 'objective' characteristics of others, we neglect the historical and discursive practices through which the social realities that we 'perceive' are actively constructed and institutionalized. We mask their social origins, contested and perspectival nature, relativity, and relationship to wider structures of power. By implication, moving beyond the Allportian perspective that has dominated both the prejudice tradition and the emerging stereotype accuracy paradigm, we may now need to prioritize other kinds of questions. Reversing Allport's famous definition of prejudice, it may now be time to ask: How, and with what consequences, does 'thinking ill of others' become sufficiently warranted? How does such thinking become part of institutionalized relations of power and an accepted way of perceiving, evaluating and treating others? What should social psychologists be doing to challenge this state of affairs? © 2017 The British Psychological Society.

    Animal models are valuable tools in fertility research. Worldwide, there are more than 400 transgenic or knockout mouse models available showing a reproductive phenotype; almost all of them exhibit an infertile or at least subfertile phenotype. By contrast, animal models revealing an improved fertility phenotype are barely described. This article summarizes data on two outbred mouse models exhibiting a 'high-fertility' phenotype. These mouse lines were generated via selection over a time period of more than 40 years and 161 generations. During this selection period, the number of offspring per litter and the total birth weight of the entire litter nearly doubled. Concomitantly with the increased fertility phenotype, several endocrine parameters (e.g. serum testosterone concentrations in male animals), physiological parameters (e.g. body weight, accelerated puberty, and life expectancy), and behavioral parameters (e.g. behavior in an open field and endurance fitness on a treadmill) were altered. We demonstrate that the two independently bred high-fertility mouse lines warranted their improved fertility phenotype using different molecular and physiological strategies. The fertility lines display female- as well as male-specific characteristics. These genetically heterogeneous mouse models provide new insights into molecular and cellular mechanisms that enhance fertility. In view of decreasing fertility in men, these models will therefore be a precious information source for human reproductive medicine.

    Urban expansion is a major driving force changing regional hydrology and nonpoint source pollution. The Haihe River Basin, the political, economic, and cultural center of northeastern China, has undergone rapid urbanization in recent decades. To investigate the consequences of future urban sprawl on nonpoint source water pollutant emissions in the river basin, the urban sprawl in 2030 was estimated, and the annual runoff and nonpoint source pollution in the Haihe River basin were simulated. The Integrated Model of Non-Point Sources Pollution Processes (IMPULSE) was used to simulate the effects of urban sprawl on nonpoint source pollution emissions. The outcomes indicated that the urban expansion through 2030 increased the nonpoint source total nitrogen (TN), total phosphorous (TP), and chemical oxygen demand (COD) emissions by 8.08, 0.14, and 149.57 kg/km(2), respectively. Compared to 2008, the total nonpoint emissions rose by 15.33, 0.57, and 12.39 %, respectively. Twelve percent of the 25 cities in the basin would increase by more than 50 % in nonpoint source TN and COD emissions in 2030. In particular, the nonpoint source TN emissions in Xinxiang, Jiaozuo, and Puyang would rise by 73.31, 67.25, and 58.61 %, and the nonpoint source COD emissions in these cities would rise by 74.02, 51.99, and 53.27 %, respectively. The point source pollution emissions in 2008 and 2030 were also estimated to explore the effects of urban sprawl on total water pollution loads. Urban sprawl through 2030 would bring significant structural changes of total TN, TP, and COD emissions for each city in the area. The results of this study could provide insights into the effects of urbanization in the study area and the methods could help to recognize the role that future urban sprawl plays in the total water pollution loads in the water quality management process.

  8. Risk of breast cancer after a diagnosis of ovarian cancer in BRCA mutation carriers: Is preventive mastectomy warranted?

    Preventive breast surgery and MRI screening are offered to unaffected BRCA mutation carriers. The clinical benefit of these two modalities has not been evaluated among mutation carriers with a history of ovarian cancer. Thus, we sought to determine whether or not BRCA mutation carriers with ovarian cancer would benefit from preventive mastectomy or from MRI screening. First, the annual mortality rate for ovarian cancer patients was estimated for a cohort of 178 BRCA mutation carriers from Ontario, Canada. Next, the actuarial risk of developing breast cancer was estimated using an international registry of 509 BRCA mutation carriers with ovarian cancer. A series of simulations was conducted to evaluate the reduction in the probability of death (from all causes) associated with mastectomy and with MRI-based breast surveillance. Cox proportional hazards models were used to evaluate the impacts of mastectomy and MRI screening on breast cancer incidence as well as on all-cause mortality. Twenty (3.9%) of the 509 patients developed breast cancer within ten years following ovarian cancer diagnosis. The actuarial risk of developing breast cancer at ten years post-diagnosis, conditional on survival from ovarian cancer and other causes of mortality was 7.8%. Based on our simulation results, among all BRCA mutation-carrying patients diagnosed with stage III/IV ovarian cancer at age 50, the chance of dying before age 80 was reduced by less than 1% with MRI and by less than 2% with mastectomy. Greater improvements in survival with MRI or mastectomy were observed for women who had already survived 10years after ovarian cancer, and for women with stage I or II ovarian cancer. Among BRCA mutation-carrying ovarian cancer patients without a personal history of breast cancer, neither preventive mastectomy nor MRI screening is warranted, except for those who have survived ovarian cancer without recurrence for ten years and for those with early stage ovarian cancer.

    To explore whether the health status of intimate partner violence (IPV) victims warrants pharmacies to be portals for public health promotion. Specific objectives included (1) identifying prevalence of IPV including domestic violence (DV) and sexual assault (SA) in a community sample, (2) describing characteristics and correlates of DV/SA between participants who reported and did not report DV/SA, and (3) exploring whether DV/SA status is related to mental health medication use. Cross sectional. Upstate New York during 2006. English- and Spanish-speaking respondents younger than 65 years of age answering four questions to assess DV/SA. Secondary analysis of a countywide random telephone survey, the 2006 Monroe County Adult Health Survey, which collects prevalence data on health behaviors and health status indicators. To determine whether those reporting DV/SA are at increased odds for mental health medication use, controlling for other sociodemographic- and health-related variables. The survey response rate was 30.3%, with 1,881 respondents meeting inclusion criteria. Those reporting DV/SA were almost twice as likely to use mental health medications. However, when controlling for other variables, only poor mental and physical health were significant in increasing the odds of mental health medication use. The analyses reported here suggest that DV/SA victims in a community sample use mental health medications. When controlling for other variables, survey respondents reported worse physical and mental health. If pharmacies are suitable portals for DV/SA outreach, curricula would need to provide the knowledge and skills needed to take an active role in this public health promotion.

    Full Text Available Pokémon is one of Nintendo’s largest, most influential franchises. With a history ranging more than twenty years, its enormous fan-base spans video and trading card games, anime TV shows and films, amongst other media. This paper aims to investigate the Pokémon fan community while exploring how the franchise has grown: from its beginnings as a pop-culture phenomenon, to one of the strongest and friendliest gaming fan communities in existence today. Data gathered from 165 online respondents examines how fans’ past experiences with the franchise inform their expectations towards future products. It also explores how considerable efforts from developers – as well as the gaming community – contribute to the creative growth of a continually-expanding fan-base. Additionally, this study was in a unique position to gather data before two new Pokémon games were released: Pokken Tournament and Pokémon GO. The former did not generate high expectations but still performed well in terms of sales. The latter was thought of as a casual game but, as the world now knows, was a tremendous success. Insights obtained from researching fan attitudes to unreleased games show that expectations do not always become reality.

    Robots are increasingly used in health care settings, e.g., as homecare assistants and personal companions. One challenge for personal robots in the home is acceptance. We describe an innovative approach to influencing the acceptance of care robots using theatrical performance. Live performance...... is a useful testbed for developing and evaluating what makes robots expressive; it is also a useful platform for designing robot behaviors and dialogue that result in believable characters. Therefore theatre is a valuable testbed for studying human-robot interaction (HRI). We investigate how audiences...... perceive social robots interacting with humans in a future care scenario through a scripted performance. We discuss our methods and initial findings, and outline future work....

    According to George Woodwell, founder of the Woods Hole Research Center, due the combustion of fossil fuels, deforestation and accelerated respiration, the net annual increase of carbon, in the form of carbon dioxide, to the 750 billion tonnes already present in the earth's atmosphere, is in the order of 3 to 5 billion tonnes. Around the world, scientists, investigating the probable effects of this increase on the earth's future climate, are now formulating coupled air and ocean current models which take account of water temperature and salinity dependent carbon dioxide exchange mechanisms acting between the atmosphere and deep layers of ocean waters

    This research examined how emotional responses to success and failure of collective action relate to willingness to engage in collective action in the future. It was hypothesized that both pride (in relation to a success) and anger (in response to failure) would motivate future collective action. Findings are reported from a two-wave longitudinal study (N= 98) in the context of student protests against tuition fees in Germany, which was conducted before and after collective action had resulted in both a success and a failure. While anger positively predicted action intentions, over and above baseline action intentions, pride exerted a significant indirect effect on action intentions via increased efficacy perceptions, over and above baseline efficacy and action intentions. Politicized identification positively predicted the intensity of both pride and anger and baseline group efficacy positively predicted the intensity of anger. The theoretical and practical implications of these findings are discussed. © 2012 The British Psychological Society.

    coagulations. The median duration of bleeding for those patients requiring multiple procedures was 7 months (range 3-33) and the median latency was 22 months (range 9-40). The 5-year actuarial rate of Grade (3(4)) complications by each scale are: RTOG 0.7%, LENT 2%, and FC-LENT 6%. The rate of chronic rectal bleeding increases with increasing dose and is low in patients treated with conventional techniques owing to lower doses. Conclusion: Chronic rectal bleeding requiring any blood transfusion(s) or multiple coagulation procedures is our most frequently observed complication. This complication appears late in follow-up and is present for a long duration. We believe this justifies the inclusion of chronic rectal bleeding requiring multiple coagulation procedures as a Grade 3 event in future morbidity scales. Our data illustrate that published Grade (3(4)) morbidity rates are highly dependent on the morbidity scale selected, as our data show 0.7% RTOG, 2% LENT, and 6% FC-LENT. Obviously, a uniform scale is required that includes the newly recognized serious late effects associated with the conformal treatment of prostate cancer

    Non-communicable diseases (i.e., chronic diseases including cardiovascular disease, cancer, chronic respiratory disease, diabetes and obesity) result in 36 million deaths each year. Individuals' habitual participation in a single health-risk behaviors substantially contribute to morbidity and mortality (e.g., tobacco use, daily fast food intake, etc.); however, more concerning is the impact of typically co-occurring or clustering of multiple health-risk behaviors. This burden can be minimized through successful cessation of health-risk behaviors and adoption of healthy behaviors; namely healthy lifestyle adoption or multiple health behavior change (MHBC). MHBC is a developing field and future research recommendations are provided to advance MHBC research. A valid measure of MHBC (i.e., lifestyle) is warranted to provide the needed basis for MHBC investigations and evaluations. MHBC is thought to occur through shared co-variation of underlying motivating mechanisms, but how these relationships influence behavior remains unclear. A better understanding of the relationship between behaviors and the related motivating mechanisms (and potential cross-relationship of influences) is needed. Future research should also aim to improve lifestyles through understanding how to change multiple health behaviors. Finally, MHBC research should target the development of sustainable interventions which result in lasting effects (e.g., capacity, systems, policy and environmental changes), with dissemination considered during development. Focusing MHBC research in these areas will increase our understanding and maximize the impact on the health of populations.

  2. Numerical investigation on an array of Helmholtz resonators for the reduction of micro-pressure waves in modern and future high-speed rail tunnel systems

    2017-07-01

    Previous research has proposed that an array of Helmholtz resonators may be an effective method for suppressing the propagation of pressure and sound waves, generated by a high-speed train entering and moving in a tunnel. The array can be used to counteract environmental noise from tunnel portals and also the emergence of a shock wave in the tunnel. The implementation of an array of Helmholtz resonators in current and future high-speed train-tunnel systems is studied. Wave propagation in the tunnel is modelled using a quasi-one-dimensional formulation, accounting for non-linear effects, wall friction and the diffusivity of sound. A multi-objective genetic algorithm is then used to optimise the design of the array, subject to the geometric constraints of a demonstrative tunnel system and the incident wavefront in order to attenuate the propagation of pressure waves. It is shown that an array of Helmholtz resonators can be an effective countermeasure for various tunnel lengths. In addition, the array can be designed to function effectively over a wide operating envelope, ensuring it will still function effectively as train speeds increase into the future.

    In August 2016, a group including sport medicine clinicians, researchers, and a bioethicist met in Vail, Colorado to discuss regenerative medicine and its potential role in youth sports injuries. There was consensus that a call to action is urgently needed to understand the current evidence base, the risks and rewards, and future directions of research and clinical practice for regenerative medicine therapies in youth sports. We present here a summary of our meeting, which was supported by the National Youth Sports Health and Safety Institute (NYSHSI), a partnership between the American College of Sports Medicine (ACSM) and Sanford Health. The group's goal is to educate practitioners and the public, and to pioneer a means of accumulating meaningful clinical data on regenerative medicine therapies in pediatric and adolescent athletes.

    Full Text Available The future singularities are possible in a universe that is described by F(R theory. In previous studies the occurrence of the singularities in F(R theory have been considered by using a special function for the Hubble parameter and calculating the F(R function for each of the singularities. Using the specified Hubble parameter causes some difficulties in the study of the second law of thermodynamics. In this paper by using the scale factor, the behavior of F(R function near each type of the singularities is considered. We can check the validity of the second law of thermodynamics near the singularities. At first we study the Little Rip and then the other types of singularities are considered. The results show that the second law of thermodynamics is satisfied near the singularity type (I with some special conditions and is violated with some other conditions. it is satisfied near the Little Rip, type (II, (III and (IV singularities

    Full Text Available Cardiovascular diseases have surpassed infectious disorders to become the leading cause of morbidity and mortality in India.1 A national-level registry comprehensively documenting the current-day prevalence of cardiovascular risk factors and disease burden among patients seeking care in the outpatient setting in India is currently non-existent. With a burgeoning urban population, the cardiovascular disease burden in India is set to skyrocket, with an estimated 18 million productive years of life lost by 2030.2 While there are limited quality improvement registries in India, for example, the Kerala acute coronary syndrome and Trivandrum heart failure registries, their focus is on in-patient care quality improvement, while the vast majority of patients with cardiovascular diseases worldwide, including India, interact with the health care system in the outpatient setting.3,4 Recognizing this unmet need, the American College of Cardiology partnered with local stakeholders in India to establish India's first outpatient cardiovascular disease performance measurement initiative in 2011, the PINNACLE (Practice Innovation and Clinical Excellence India Quality Improvement Program (PIQIP.5 This manuscript discusses the inception of the PIQIP registry, the progress it has made and challenges thus far, and its future direction and the promise it holds for cardiovascular care quality improvement in India.

    2000-01-01

    Due to contradictory opinions on the role of peat as a renewable energy source and carbon sink as well as the fact that no comprehensive research are made in this area, the Finnish Ministry of Trade and Industry (KTM) assigned an impartial working group to investigate the role of peat in climatic change. The working group consists of Patrick Crill from USA, Ken Hargreaves from Great Britain, and Atte Korhola from Finland. The objective of the working group is to study the greenhouse gas balances of virgin peatland, ditched peatlands, and cultivated peatlands. The carbon cycles will be investigated, as well as the effects of utilisation of peat on greenhouse gas balance, and the possibilities of effecting the balance with active measures. The alternatives for utilisation peatlands after the peat has been harvested, and the effects of these alternatives on greenhouse gas balance will also be studied. The effects of the peatlands left in passive natural state, the regeneration of peatlands, forestation and other usage on greenhouse gas balance will be investigated, and the need for regulations and instructions for recycling have to be estimated. The greenhouse gas emissions and the carbon sinks have to be defined, the alternative means for definition of them have to be inspected. The mutual dependence of peat and wood fuels has also to be taken into consideration. The report will to include the effects of peat on watercourses, versatility of the nature, the effect of the peat production on the amount of peat production areas, and suggestions for possible need of further investigations

    A key task for biomedical human support in long-term manned space expeditions is the develop-ment of the Life Support System (LSS). It is expected that in the first continuous interplanetary expeditions LSS of only a few biological elements of the LSS, such as higher plants will be in-cluded. Therefore, investigations of growth and development of higher plants for consideration in the LSS are of high importance. In a period from October, 2002 to December 2009, 15 ex-periments on cultivation of different plants, including two genetically marked species of dwarf peas, a leaf vegetable strain of Mizuna, radish, barley and wheat were conducted in space greenhouse "LADA" onboard Russian Segment (RS) of International Space Station (ISS). The experiments resulted in the conclusion that the properties of growth and development of plants grown in space greenhouse "LADA" were unaffected by spaceflight conditions. In experiments conducted in a period from 2003 to 2005, it was shown for the first time that pea plants pre-serve reproductive functions, forming viable seeds during at least four continuous full cycles of ontogenesis ("seed to seed") under spaceflight conditions. No changes were found in the genetic apparatus of the pea plants in the four "space" generations. Since 2005, there have been routine collections of microbiological samples from the surfaces of the plants grown on-board in "LADA" greenhouse. Analysis has shown that the properties of contamination of the plants grown aboard by microorganism contain no abnormal patterns. Since 2008, the plants cultivated in "LADA" greenhouse have been frozen onboard RS ISS in the MELFI refrigerator and transferred to the Earth for further investigations. Investigations of Mizuna plants grown and frozen onboard of ISS, showed no differences between "ground control" and "space" plants in chemical and biochemical properties. There also no stress-response was found in kashinriki strain barley planted and frozen onboard ISS.

    Full Text Available Educational institutions are one of the main trip generators and distributors in the cities around the world. The main campus of the University of Kufa has more than 10 faculties with more than 12,000 people (staff and students. This makes the university is one of the high attracting area of trips in the city. These attracted trips use different modes of transportation such as taxi, private car, min-bus and even walking mode. This study aims to investigate the travel behavior and travel patterns for the current trips and put the suitable suggestions for shifting the travel characteristics using efficient modern modes of transportation. More than 4000 samples have been investigated using interviews asking about the origin, the purpose of trips and the mode of trips. The results of this analysis indicate the urgent need for improving the current transportation system by encouraging public transport such as bus and tram. Moreover, there is a need for improving the design and traffic management for the gates of the university.

    To compare clinical assessment of diabetic eye disease by standard dilated examination with data gathered using a smartphone-based store-and-forward teleophthalmology platform. 100 eyes of 50 adult patients with diabetes from a health care safety-net ophthalmology clinic. All patients underwent comprehensive ophthalmic examination. Concurrently, a smartphone was used to estimate near visual acuity and capture anterior and dilated posterior segment photographs, which underwent masked, standardized review. Quantitative comparison of clinic and smartphone-based data using descriptive, kappa, Bland-Altman, and receiver operating characteristic analyses was performed. Smartphone visual acuity was successfully measured in all eyes. Anterior and posterior segment photography was of sufficient quality to grade in 96 and 98 eyes, respectively. There was good correlation between clinical Snellen and smartphone visual acuity measurements (rho = 0.91). Smartphone-acquired fundus photographs demonstrated 91% sensitivity and 99% specificity to detect moderate nonproliferative and worse diabetic retinopathy, with good agreement between clinic and photograph grades (kappa = 0.91 ± 0.1, P smartphone-based telemedicine system that demonstrated sensitivity and specificity to detect referral-warranted diabetic eye disease as a proof-of-concept.

    TMI-2 altered the perception of the likelihood of severe accidents and their precursors and shortly after the accident, changes began at the NRC. NRC required its nuclear power licensees to make a rather large number of back fits to respond to the lessons learned; NRC broadened the study of severe accident phenomena (focus on studies involving molten core materials); other lessons learned concerned the severe accident source terms and the shift from a deterministic tradition point of view to a probabilistic risk assessment formalism. A Revised Severe Accident Research Program Plan was issued in 1989. A review of what was known before the TMI-Vessel Investigation Project and what was not known, is presented

    The irrigated dairy industry in southern Australia has experienced significant restrictions in irrigation water allocations since 2005, consistent with climate change impact predictions for the region. Simulation models of pasture growth (DairyMod), crop yield (Agricultural Production Systems Simulator, APSIM), and dairy system management and production (UDDER) were used in combination to investigate a range of forage options that may be capable of sustaining dairy business profitability under restricted water-allocation scenarios in northern Victoria, Australia. A total of 23 scenarios were simulated and compared with a base farm system (100% of historical water allocations, grazed perennial ryegrass pasture with supplements; estimated operating surplus $A2,615/ha at a milk price of $A4.14/kg of milk solids). Nine simulations explored the response of the base farm to changes in stocking rate or the implementation of a double cropping rotation on 30% of farm area, or both. Five simulations explored the extreme scenario of dairying without any irrigation water. Two general responses to water restrictions were investigated in a further 9 simulations. Annual ryegrass grazed pasture, complemented by a double cropping rotation (maize grown in summer for silage, followed by either brassica forage crop and annual ryegrass for silage in winter and spring) on 30% of farm area, led to an estimated operating surplus of $A1746/ha at the same stocking rate as the base farm when calving was moved to autumn (instead of late winter, as in the base system). Estimated total irrigation water use was 2.7ML/ha compared with 5.4ML/ha for the base system. Summer-dormant perennial grass plus double cropping (30% of farm area) lifted operating surplus by a further $A100/ha if associated with autumn calving (estimated total irrigation water use 3.1ML/ha). Large shifts in the forage base of dairy farms could sustain profitability in the face of lower, and fluctuating, water allocations

    @@ 2005 was a quiet year for China's futures market.After four new trading products, including cotton, fuel oil and corn, were launched on the market in 2004, the development of the market seemed to stagnate. The trade value of the futures market totaled 13.4 trillion yuan (US$ 1.67 trillion) in 2005, down 8.5 percent year-on-year. Although the decrease is quite small and the trade value was still the second highest in the market's history, the majority of futures brokerage firms were running in the red. In some areas, up to 80 percent of futures companies made losses.

    2005-12-01

    Full Text Available Italy was the last Member State to transpose the Framework Decision on the European Arrest Warrant. The Italian law entered into full force on 14 May 2005, a full sixteen months later than the appointed date. Conversely, whilst the Framework Decision aimed to speed up extradition between Member States, the Italian implementation law seems to complicate things, providing for dozens of new legal obstacles to surrender. In fact, the execution of an EAW in Italy threatens to become something highly unpredictable. The responsibility for this outcome is shared by the national and the European legislator. Perhaps the latter underestimated the seriousness of the conflict between Third Pillar law and domestic constitutional systems which aim to protect their acquis in the field of fundamental rights. Considering that many Member States seem to be struggling with similar problems, the first part of this article is devoted to describing the current scenario and analysing possible solutions at the supranational level, such as the establishment of a coherent system regulating the allocation of penal competences among Member States. In the next part, the problem of the Framework Decision’s incompatibility with the Italian Constitution will be discussed, and in the final part the Italian implementation law is analysed in more detail.

    In order to investigate many-particle reaction dynamics in atomic collisions a novel high-resolution technique has been developed, which determines the momentum and the charge state of the slowly recoiling target ions. Using a very cold, thin, and localized supersonic gas jet target a momentum resolution of better than 0.05 a.u. is obtained by measuring the recoil-ion time-of-flight and the recoil-ion trajectory. Because of the very high detection efficiency of nearly 100% this technique is well suited for many-particle coincidence measurements in ionizing collisions. First experimental results for fast ion and electron impact on helium targets are presented. Future applications in atomic collision physics and related areas are discussed. (orig.)

    2012-03-01

    Full Text Available The numerous advantages offered by cloud computing has fuelled its growth and has made it one of the most significant of current computing trends. The same advantages have created complex issues for those conducting digital forensic investigations. Digital forensic investigators rely on the ACPO guidelines when conducting an investigation, however the guidelines make no reference to some of the issues presented by cloud investigations.This study investigates the impact of cloud computing on ACPO’s core principles and asks whether there is a need for the principles and guidelines to be reviewed to address the issues presented by cloud computing. Empirical research is conducted and data collected from key experts in the field of digital forensics.This research presents several key findings: there is a very real concern for how cloud computing will affect digital forensic investigations; the ACPO principles cannot easily be applied in all cloud investigations but are generally sufficient for cloud computing forensic investigations. However the advent of cloud computing is a significant development in technology and may in the near future warrant a review of the guidelines in particular to incorporate the involvement of third parties in cloud investigations.

    This study sought to investigate the component processes underlying the ability to imagine future events, using an individual-differences approach. Participants completed several tasks assessing different aspects of future thinking (i.e., fluency, specificity, amount of episodic details, phenomenology) and were also assessed with tasks and questionnaires measuring various component processes that have been hypothesized to support future thinking (i.e., executive processes, visual-spatial processing, relational memory processing, self-consciousness, and time perspective). The main results showed that executive processes were correlated with various measures of future thinking, whereas visual-spatial processing abilities and time perspective were specifically related to the number of sensory descriptions reported when specific future events were imagined. Furthermore, individual differences in self-consciousness predicted the subjective feeling of experiencing the imagined future events. These results suggest that future thinking involves a collection of processes that are related to different facets of future-event representation.

    Detection of treatment-requiring retinopathy of prematurity (ROP) involves serial eye examinations. An ROP prediction model using predictive factors could identify high-risk infants and reduce required eye examinations. To determine predictive factors for the development of referral-warranted (RW) ROP. This multicenter observational cohort study included secondary analysis of data from the Telemedicine Approaches to Evaluating Acute-Phase Retinopathy of Prematurity Study. Infants included in the study had a birth weight (BW) of less than 1251 g. Serial ROP examinations of premature infants who had 2 or more ROP examinations. Incidence of RW-ROP (defined as the presence of plus disease, zone I ROP, or ROP stage 3 or greater in either eye) and associations with predictive factors. Among 979 infants without RW-ROP at first study-related eye examination (median postmenstrual age, 33 weeks; range, 29-40 weeks) who underwent at least 2 eye examinations, 149 (15.2%) developed RW-ROP. In a multivariate model, significant predictors for RW-ROP were male sex (odds ratio [OR], 1.80; 95% CI, 1.13-2.86 vs female), nonblack race (OR, 2.76; 95% CI, 1.50-5.08 for white vs black race and OR, 4.81; 95% CI, 2.19-10.6 for other vs black race), low BW (OR, 5.16; 95% CI, 1.12-7.20 for ≤500 g vs >1100 g), younger gestational age (OR, 9.79; 95% CI, 3.49-27.5 for ≤24 weeks vs ≥28 weeks), number of quadrants with preplus disease (OR, 7.12; 95% CI, 2.53-20.1 for 1-2 quadrants and OR, 18.4; 95% CI, 4.28-79.4 for 3-4 quadrants vs no preplus disease), stage 2 ROP (OR, 4.13; 95% CI, 2.13-8.00 vs no ROP), the presence of retinal hemorrhage (OR, 4.36; 95% CI, 1.57-12.1 vs absence), the need for respiratory support (OR, 4.99; 95% CI, 1.89-13.2 for the need for controlled mechanical ventilator; OR, 11.0; 95% CI, 2.26-53.8 for the need for high-frequency oscillatory ventilation vs no respiratory support), and slow weight gain (OR, 2.44; 95% CI, 1.22-4.89 for weight gain ≤12 g/d vs >18 g

    Food systems have changed markedly with human settlement and agriculture, industrialisation, trade, migration and now the digital age. Throughout these transitions, there has been a progressive population explosion and net ecosystem loss and degradation. Climate change now gathers pace, exacerbated by ecological dysfunction. Our health status has been challenged by a developing people-environment mismatch. We have regarded ecological conquest and innovative technology as solutions, but have not understood how ecologically dependent and integrated we are. We are ecological creatures interfaced by our sensoriness, microbiomes, shared regulatory (endocrine) mechanisms, immune system, biorhythms and nutritional pathways. Many of us are 'nature-deprived'. We now suffer what might be termed ecological health disorders (EHD). If there were less of us, nature's resilience might cope, but more than 9 billion people by 2050 is probably an intolerable demand on the planet. Future food must increasingly take into account the pressures on ecosystem-dependent food systems, with foods probably less biodiverse, although eating in this way allows optimal health; energy dysequilibrium with less physical activity and foods inappropriately energy dense; and less socially-conducive food habits. 'Personalised Nutrition', with extensive and resource-demanding nutrigenomic, metabolomic and microbiomic data may provide partial health solutions in clinical settings, but not be justified for ethical, risk management or sustainability reasons in public health. The globally prevalent multidimensional malnutritional problems of food insecurity, quality and equity require local, regional and global action to prevent further ecosystem degradation as well as to educate, provide sustainable livelihoods and encourage respectful social discourse and practice about the role of food.

  20. Multifactor valuation models of energy futures and options on futures

    Science.gov (United States)

    Bertus, Mark J.

    The intent of this dissertation is to investigate continuous time pricing models for commodity derivative contracts that consider mean reversion. The motivation for pricing commodity futures and option on futures contracts leads to improved practical risk management techniques in markets where uncertainty is increasing. In the dissertation closed-form solutions to mean reverting one-factor, two-factor, three-factor Brownian motions are developed for futures contracts. These solutions are obtained through risk neutral pricing methods that yield tractable expressions for futures prices, which are linear in the state variables, hence making them attractive for estimation. These functions, however, are expressed in terms of latent variables (i.e. spot prices, convenience yield) which complicate the estimation of the futures pricing equation. To address this complication a discussion on Dynamic factor analysis is given. This procedure documents latent variables using a Kalman filter and illustrations show how this technique may be used for the analysis. In addition, to the futures contracts closed form solutions for two option models are obtained. Solutions to the one- and two-factor models are tailored solutions of the Black-Scholes pricing model. Furthermore, since these contracts are written on the futures contracts, they too are influenced by the same underlying parameters of the state variables used to price the futures contracts. To conclude, the analysis finishes with an investigation of commodity futures options that incorporate random discrete jumps.

  1. The alternative energy future

    Spitzley, H.

    1989-02-01

    The alternative energy future can be achieved only by making energy conservation programmes successful, and by fully committing to the utilization of soft energy sources. This is the perspective drawn by the author who in this book investigates the fundamentals of an ecologically and socially sound energy policy for the future. Looking at California, USA, where completely near concepts have been put to work in the energy sector since the mid-seventies, the author shows how it can be done, by rewarding energy conserving activities, using available energy sources more efficiently, developing the means for renewable energy exploitation wherever appropriate. A turn in energy policy is feasible also in West Germany, both in technical and political terms. Starting from the experience gained in the USA, the author presents an outline of options and potentials of a new energy strategy for the Federal Republic of Germany. (orig./HP) [de

    Although routine outcome monitoring (ROM) has been developed and widely used in the course of patient centered outcome research in the Netherlands, so far the technique has hardly ever been used to improve the treatment of individual patients. To describe how a rom technique based on the principles of shared decision-making (SDM) was developed and evaluated at the Center for Body, Mind and Health at GGz Breburg, a specialised mental health institution in the Netherlands. We have developed a conceptual model for SDM that involves patient participation and the use of evidence-based decision-aids with cut-off scores. According to the conceptual model for SDM that we developed, the patient and the health professional involved took 'shared' decisions in three phases; the decisions related to triage, the drawing-up of a treatment plan and a follow-up treatment course. At the end of the 6 month intake-phase 7 of the 67 patients who were deemed eligible for ROM/SDM were dropped from the study because they were incapable of performing ROM assessments. Due to diagnostic advice and referral at the end of the intake-phase, 25 patients did not require further treatment. Of the remaining 35 patients, 33 delivered at least one follow-up ROM assessment during the subsequent treatment phases. In these patients somatic and psychiatric symptoms were found to be significantly reduced. ROM combined with sdm can be used successfully with patients who have a combination of physical and psychiatric symptoms and the technique can be applied by the professional in charge. Very few patients dropped out of the follow-up measurements and somatic as well as depressive or psychiatric symptoms diminished significantly. These findings indicate that a Randomised Clinical Trial is warranted in order to test the effectiveness of sdm combined with ROM as a decision-making instrument.

    Biogas is expected to play an important role in reaching the future energy policy targets of the European Union (EU). The sustainability of biogas substrates has however been recently critically discussed due to the increasing shares of agricultural land used for energy crop production.The aim...... of this study was to project and map the biomass and biogas energy potential from a selection of potentially sustainable agricultural residues, which have been documented to improve in biogas yields when co-digested in biogas production, for the EU28 in year 2030. The investigated types of residual biomasses...... were animal manure, straw by-products from cereal production, and excess grass from rotational and permanent grasslands and meadows. The biogas energy potential from the investigated biomass was projected to range from 1.2·103 to 2.3·103 PJ y-1 in year 2030 in the EU28, depending on the biomass...

    From 1973 through 1987, 155 radioisotope-powered nuclear pacemakers were implanted in 132 patients at the Newark Beth Israel Medical Center. The longevity of the first 15 devices, all of which were fixed-rate (VOO) pacemakers, was significantly better than that of 15 lithium-chemistry demand (VVI) pacemakers used as control devices (p = 0.0002). Of the entire cohort of 155 nuclear pacemakers, 136 were VVI devices and 19 were VOO units. The patients with VOO pacemakers needed reoperations more often than did those with VVI pacemakers, chiefly for mode change (p less than 0.001). Power-source failure was observed in only 1 case, but 47 nuclear pacemakers were removed for other reasons, including component malfunction (15 units), mode change (12 units), high pacing thresholds (8 units) and lead or connector problems (5 units). The actuarial survival at 15 years was 99% for power sources and 82% for the entire pacing systems (pulse generators plus leads). The frequency of malignancy was similar to that of the population at large and primary tumor sites were randomly distributed. Deaths most commonly were due to cardiac causes (68%). Thus, nuclear pacemakers are safe and reliable and their greater initial cost appears to be offset by their longevity and the resulting decrease in the frequency of reoperations. It is reasonable to suggest that further use be made of long-lasting nuclear power sources for modern pacemakers and other implantable rhythm-management devices

    A key argument in favor of conserving biodiversity is that as yet undiscovered biodiversity will yield products of great use to humans. However, the link between undiscovered biodiversity and useful products is largely conjectural. Here we provide direct evidence from bioassays of endophytes isolated from tropical plants and bioinformatic analyses that novel biology will indeed yield novel chemistry of potential value. We isolated and cultured 135 endophytic fungi and bacteria from plants collected in Peru. nrDNAs were compared to samples deposited in GenBank to ascertain the genetic novelty of cultured specimens. Ten endophytes were found to be as much as 15-30% different than any sequence in GenBank. Phylogenetic trees, using the most similar sequences in GenBank, were constructed for each endophyte to measure phylogenetic distance. Assays were also conducted on each cultured endophyte to record bioactivity, of which 65 were found to be bioactive. The novelty of our contribution is that we have combined bioinformatic analyses that document the diversity found in environmental samples with culturing and bioassays. These results highlight the hidden hyperdiversity of endophytic fungi and the urgent need to explore and conserve hidden microbial diversity. This study also showcases how undergraduate students can obtain data of great scientific significance.

    Two science-arts approaches are emerging as effective means to convey "futurethinking" to learners: systems gaming and experiential futures. FutureCoast exemplifies the latter: by engaging participants with voicemails supposedly leaking from the cloud of possible futures, the storymaking game frames the complexities of climate science in relatable contexts. Because participants make the voicemails themselves, FutureCoast opens up creative ways for people to think about possibly climate-changed futures and personal ways to talk about them. FutureCoast is a project of the PoLAR Partnership with a target audience of informal adult learners primarily reached via mobile devices and online platforms. Scientists increasingly use scenarios and storylines as ways to explore the implications of environmental change and societal choices. Stories help people make connections across experiences and disciplines and link large-scale events to personal consequences. By making the future seem real today, FutureCoast's framework helps people visualize and plan for future climate changes. The voicemails contributed to FutureCoast are spread through the game's intended timeframe (2020 through 2065). Based on initial content analysis of voicemail text, common themes include ecosystems and landscapes, weather, technology, societal issues, governance and policy. Other issues somewhat less frequently discussed include security, food, industry and business, health, energy, infrastructure, water, economy, and migration. Further voicemail analysis is examining: temporal dimensions (salient time frames, short vs. long term issues, intergenerational, etc.), content (adaptation vs. mitigation, challenges vs. opportunities, etc.), and emotion (hopeful, resigned, etc. and overall emotional context). FutureCoast also engaged audiences through facilitated in-person experiences, geocaching events, and social media (Tumblr, Twitter, Facebook, YouTube). Analysis of the project suggests story

    What will teachers need in the future to be successful? What will "successful" mean in the future? Are the teaching approaches learned 40 years ago still relevant for tomorrow's classrooms? Will technology really change the way physics is taught (K-16)? Will we close the performance gap between students of differing ethnicity? Are schools of education rising to the challenge to answer these questions? Can college and university physics departments rise to the challenge of presenting physics to all students in an engaging manner? What can the APS, in partnership with AAPT and AIP, do to find the answers and provide strategies to improve the science preparation of future teachers? PhysTEC aims to help physics and education faculty work together to provide an education for future teachers that emphasizes a student-centered, hands-on, inquiry-based approach to learning science. The compelling evidence produced from Physics Education Research warrants this approach. A National Science Foundation grant of 5.76 million and a 498 thousand grant from the Fund for the Improvement of Postsecondary Education support PhysTEC, its partners and activities. http://www.phystec.org/

Past thinking triggered more fixation (p thinking. Past and future thinking triggered a similar duration of fixations and saccades, as well as a similar amplitude of saccades. Interestingly, participants rated past thinking as more vivid than future thinking (p thinking seems to be accompanied by an increased number of fixations and saccades. Fixations and saccades in past thinking can be interpreted as an attempt by the visual system to find (through saccades) and activate (through fixations) stored memory representations. The same interpretation can be applied to future thinking as this ability requires activation of past experiences. However, future thinking triggers fewer fixations and saccades than past thinking: this may be due to its decreased demand on visual imagery, but could also be related to a potentially deleterious effect of eye movements on spatial imagery required for future thinking.

    Full Text Available This article focuses on the development of a framework for investigating the personal financial management knowledge of individuals. Content analysis is used to derive the components included in the personal financial management requirements framework. The framework developed includes six components, namely basic concepts in personal finances, management of personal finances, risk management, future planning, investing in financial resources and miscellaneous factors. A qualitative validation process revealed that the framework indeed covers what the average South African citizen is required to know about personal financial planning. The real test of this framework will be to use it in developing an instrument to test individuals’ knowledge of personal financial management. This process of empirically testing the framework, using such an instrument, warrants a separate article.

    In recent years, the electric industry has undergone dramatic changes as the federal and state governments have encouraged bulk power production by Independent Power Producers (IPPS) and Qualified Facilities (QFs). With decentralization and the consequent competition in the field of bulk power production, there has emerged the problem of non-utility generators (NUGS) and of transmission dependent utilities accessing the existing transmission systems owned by electric utilities. This paper presents current and future issues related to transmission access by IPPS, QFs and transmission dependent utilities. These issues include: (a) impact on system reliability, (b) impact of pricing strategies, (c) changes in state and federal regulations, (d) transmission proposals by various entities, (e) present access arrangements, (f) formation of the Western Systems Power Pool (WSPP), and (g) siting difficulties. The transmission access problem warrants consideration of transmission services, coordination among electric utilities, joint planning on a regional basis, and accommodation of IPPs and NUGs

The origin and the total number of all antibiotics and applied antibiotics in the practice, as well as the bioactive microbial metabolites (antibiotics) in other therapeutical, non-antibiotic fields (including agriculture) are also reviewed. The author discusses main problems, such as increasing (poly)resistance, virulence of pathogens and the non-scientific factors (such as a decline of research efforts and their sociological, economic, financial and regulatory reasons). A short summary of the history of Hungarian antibiotic research is also provided. The author briefly discusses the prospects in the future and the general advantages of the natural products over synthetic compounds. It is concluded that new approaches for the investigation of the unlimited possibilities of the living world are necessary. The discovery of new types or simply neglected (micro)organisms and their biosynthetic capabilities, the introduction of new biotechnological and genetic methods (genomics, metagenom, genome mining) are absolutely required in the future.

    2012-12-01

    The Renewable Electricity Futures (RE Futures) Study investigated the challenges and impacts of achieving very high renewable electricity generation levels in the contiguous United States by 2050. The analysis focused on the sufficiency of the geographically diverse U.S. renewable resources to meet electricity demand over future decades, the hourly operational characteristics of the U.S. grid with high levels of variable wind and solar generation, and the potential implications of deploying high levels of renewables in the future. RE Futures focused on technical aspects of high penetration of renewable electricity; it did not focus on how to achieve such a future through policy or other measures. Given the inherent uncertainties involved with analyzing alternative long-term energy futures as well as the multiple pathways that might be taken to achieve higher levels of renewable electricity supply, RE Futures explored a range of scenarios to investigate and compare the impacts of renewable electricity penetration levels (30%-90%), future technology performance improvements, potential constraints to renewable electricity development, and future electricity demand growth assumptions.

    Our life develops as the anticipation of future. Everything we wish, hope, plan and carry out and think is or should be related to future and will have its effects in future. The certainty may spread that it is a necessary obligation to learn to find out our actual being more clearly to be able to develop a thinking and acting that is directed to future that has also a total of responsability as its essence. We will later atone for the failed outlooks into future or for only moderate or uncompleted starts of planning. For this reason we should consider that future does not come for its own, not without our demands, not without our acting. Only if our reflection and aspiration, thinking and acting is done with moderate and circumspect sense in the right way it will be a good fundamental for the future. (orig.) [de

    Full Text Available The aim of the study is to determine the factors that affect the volatility perception of warrant investors. By using 3.187 daily data of 61 call warrants whose underlying asset is BIST-30 Index and traded on BIST in 2012, firstly efficient option pricing model for the related market is confirmed and then volatilities that equalizes the efficient model prices to market prices are calculated and regression analysis is applied to determine factors that affect the volatility. The results of the analysis are revealed that if the closing price of the underlying asset, the days to maturity of the warrant and Turkish Lira Interbank rate increase, the volatility perceived by investors will decrease. Also, there is positive relationship between the closing price of warrants and the perceived volatility. In addition perceived volatility is higher on Monday and first decrease in inflation after 4 months increase reduces the perceived volatility.

  9. Queering Aging Futures

    Directory of Open Access Journals (Sweden)

    Linn J. Sandberg

    2017-08-01

    Full Text Available This paper explores the potential for cultural gerontology to extend its ideas of diversity in aging experiences by opening space to rethink conceptions of successful aging futures. We propose a ‘queering’ of aging futures that disrupts the ways that expectations of a good later life and happy aging are seen to adhere to some bodies and subjectivities over others. Drawing on feminist, queer, and crip theories, we build on existing critiques of ‘successful aging’ to interrogate the assumptions of heteronormativity, able-bodiedness and able-mindedness that shape the dividing lines between success and failure in aging, and which inform attempts to ‘repair’ damaged futures. Conclusions suggest that recognizing diversity in successful aging futures is important in shaping responses to the challenges of aging societies, and presents an opportunity for critical cultural gerontology to join with its theoretical allies in imagining more inclusive alternatives.

    To assess whether or not a sample of PGY-1 doctors in the Waikato region remained satisfied with the ACE system for employment 12 years after its inception. An anonymous paper-based survey was completed by a cohort (n=60) of 2015 and 2016 PGY-1 doctors based at the Waikato DHB. Questions were based around reasons for selecting the DHB, satisfaction with the ACE process and future career intentions. Overall satisfaction with the ACE selection process was reasonable (63%). Over 60% of the 2015 and 2016 cohorts chose Waikato as their first choice DHB, and of those, over 90% intended to carry on through to at least PGY2 level at the DHB. An overwhelming majority (93-96%) intended to continue practicing in New Zealand. Consistent trends were observed across the two cohorts in regards to their reasons for selecting the DHB, satisfaction with ACE and future intentions, with some differences observed with familial background and interest in pursuing hospital-based specialties. Our findings suggest that ACE remains a satisfactory recruiting system for postgraduate junior doctors, however, motives around initial DHB selection and future vocational intentions remain unclear and warrant further investigation.

DOE began the ''Future Land Use'' initiative in 1994 to ensure that its cleanup efforts reflect the surrounding communities' interests in future land use. This plan presents the results of a study of stakeholder-preferred future land uses for the Brookhaven National Laboratory (BNL), located in central Long Island, New York. The plan gives the Laboratory's view of its future development over the next 20 years, as well as land uses preferred by the community were BNL ever to cease operations as a national laboratory (the post-BNL scenario). The plan provides an overview of the physical features of the site including its history, topography, geology/hydrogeology, biological inventory, floodplains, wetlands, climate, and atmosphere. Utility systems and current environmental operations are described including waste management, waste water treatment, hazardous waste management, refuse disposal and ground water management.

The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this AMR provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the infiltration model (USGS 2000) and for the total system performance assessment for the Site Recommendation (TSPA-SR) at YM. Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one method, among many, of establishing upper and lower bounds for future climate estimates. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate.

    2014-12-01

    Changes in climate, natural vegetation and human land use are expected to significantly influence air quality in the coming century. These changes and their interactions have important ramifications for the effectiveness of air pollution control strategies. In a series of studies, we use a one-way coupled modeling framework (GEOS-Chem driven by different combinations of historical and future meteorological, land cover and emission data) to investigate the effects of climate-vegetation changes on global and East Asian ozone air quality from 30 years ago to 40 years into the future. We find that future climate and climate-driven vegetation changes combine to increase summertime ozone by 2-6 ppbv in populous regions of the US, Europe, East Asia and South Asia by year 2050, but including the interaction between CO2 and biogenic isoprene emission reduces the climate impacts by more than half. Land use change such as cropland expansion has the potential to either mostly offset the climate-driven ozone increases (e.g., in the US and Europe), or greatly increase ozone (e.g., in Southeast Asia). The projected climate-vegetation effects in East Asia are particularly uncertain, reflecting a less understood ozone production regime. We thus further study how East Asian ozone air quality has evolved since the early 1980s in response to climate, vegetation and emission changes to shed light on its likely future course. We find that warming alone has led to a substantial increase in summertime ozone in populous regions by 1-4 ppbv. Despite significant cropland expansion and urbanization, increased summertime leafiness of vegetation in response to warming and CO2 fertilization has reduced ozone by 1-2 ppbv, driven by enhanced ozone deposition dominating over elevated biogenic emission and partially offsetting the warming effect. The historical role of CO2-isoprene interaction in East Asia, however, remains highly uncertain. Our findings demonstrate the important roles of land cover

    The events in the nuclear industry are investigated from the license point of view and from the regulatory side too. It is well known the importance of the event investigation. One of the main goals of such investigation is to prevent the circumstances leading to the event and the consequences of the event. The protection of the nuclear workers against nuclear hazard, and the protection of general public against dangerous effects of an event could be achieved by systematic approach to the event investigation. Both, the nuclear safety regulatory body and the licensee shall ensure that operational significant events are investigated in a systematic and technically sound manner to gather information pertaining to the probable causes of the event. One of the results should be appropriate feedback regarding the lessons of the experience to the regulatory body, nuclear industry and general public. In the present paper a general description of systematic approach to the event investigation is presented. The systematic approach to the event investigation works best where cooperation is present among the different divisions of the nuclear facility or regulatory body. By involving management and supervisors the safety office can usually improve their efforts in the whole process. The end result shall be a program which serves to prevent events and reduce the time and efforts solving the root cause which initiated each event. Selection of the proper method for the investigation and an adequate review of the findings and conclusions lead to the higher level of the overall nuclear safety. (author)

  7. Limited field investigation report for the 100-FR-1 Operable Unit

    International Nuclear Information System (INIS)

    1995-09-01

    This limited field investigation (LFI) report summarizes the data collection and analysis activities conducted during the 100-FR-1 Source Operable Unit LFI and the associated qualitative risk assessment (QRA), and makes recommendations on the continued candidacy of high-priority sites for interim remedial measures (IRM). The results and recommendations presented in this report are generally independent of future land use scenarios. An LFI is required when existing data are insufficient to formulate a conceptual model and perform a QRA. The purpose of the report is to identify those sites that are recommended to remain as candidates for IRM, provide a preliminary summary of site characterization studies, refine the conceptual model as needed, identify contaminant- and location-specific applicable or relevant and appropriate requirements (ARAR), and provide a qualitative assessment of the risks associated with the sites. This assessment includes consideration of whether contaminant concentrations pose an unacceptable risk that warrants action through IRM. The final decision to conduct an IRM will rely on many factors including risk, ARAR, future land use, point of compliance, time of compliance, a bias-for-action, and the threat to human health and the environment

  8. Future trends in reprocessing

    International Nuclear Information System (INIS)

    Rouyer, H.

    1994-01-01

    This paper about future trends in reprocessing essentially reflects French experience and points of view as an example of countries which, like England and Japan, consider that reprocessing is the best solution for the back end of the fuel cycle. In order to know what the future will be, it is necessary to look back at the past and try to find what have been the main reasons for evolution in that period. For reprocessing, it appears that these motivations have been 'safety and economics'. They will remain the motivations for the future. In addition, new motivations for development are starting to appear which are still imprecise but can be expressed as follows: 'which guarantees will public opinion require in order to be convinced that solutions for waste management, proposed by specialists shall ensure that a healthy environment is preserved for the use of future generations'. Consequently the paper examines successively the evolution of reprocessing in the recent past, what the immediate future could be and finally what should be necessary in the long term. (Author)

  9. Future fuel cycles

    International Nuclear Information System (INIS)

    Archinoff, G.H.

    1980-01-01

    A fuel cycle must offer both financial and resource savings if it is to be considered for introduction into Ontario's nuclear system. The most promising alternative CANDU fuel cycles are examined in the context of both of these factors over a wide range of installed capacity growth rates and economic assumptions, in order to determine which fuel cycle, or cycles, should be introduced, and when. It is concluded that the optimum path for the long term begins with the prompt introduction of the low-enriched-uranium fuel cycle. For a wide range of conditions, this cycle remains the optimum throughout the very long term. Conditions of rapid nuclear growth and very high uranium price escalation rates warrant the supersedure of the low-enriched-uranium cycle by either a plutonium-topped thorium cycle or plutonium recycle, beginning between 2010 and 2025. It is also found that the uranium resource position is sound in terms of both known resources and production capability. Moreover, introduction of the low-enriched-uranium fuel cycle and 1250 MWe reactor units will assure the economic viability of nuclear power until at least 2020, even if uranium prices increase at a rate of 3.5% above inflation. The interrelationship between these two conclusions lies in the tremendous incentive for exploration which will occur if the real uranium price escalation rate is high. From a competitive viewpoint, nuclear power can withstand increases in the price of uranium. However, such increases will likely further expand the resource base, making nuclear an even more reliable energy source. (auth)

    2010-01-01

    Abstract West Greenlandic, a polysynthetic language, belongs to Inuit languages. In Inuktitut (Canada) and West Greenlandic (Inuit languages) tense is marked by optional tense suffixes and in both languages the temporal systems are based on a future/ non-future opposition. In Inuktitut the tense...... suffixes have developed a complicated remoteness system. In West Greenlandic the future tense suffixes have a distinction between vague and inevitable future, and the past time suffixes have developed different perfect meanings. In Iñupiaq (Alaska), the temporal system is based on an opposition between...... past, present and future, where tense is marked in the flectional morpheme, but only in the indicative mood. There are only a few tense suffixes. The meanings of these tense suffixes are the same as those of the West Greenlandic tense suffixes. My current work is a typological investigation about...

For making up powerful and strong visions and policies for sustainable cities, ‘collaborative storytelling’ plays a key role. The theoretical outset for the research project ‘Mobilities, Futures & the City’, which grounds......The future of cities and regions will be strongly shaped by the mobilities of people, goods, modes of transport, waste and information. In many ways, the ‘why and ‘for what’ often get lost in discourses on planning and designing mobilities. The predominant planning paradigm still conceptualizes...... the future of cities and mobilities as a matter of rather more efficient technologies than of social cohesion, integration and connectivity. Sustainable mobility needs the mobilities of ideas and concepts and the reflexivity of policies. Communicative planning theory and the ‘argumentative turn’ have given...

    1999-01-01

    After a brief review of the Big Issues in particle physics, we discuss the contributions to resolving that could be made by various planned and proposed future colliders. These include future runs of LEP and the Fermilab Tevatron collider, B factories, RHIC, the LHC, a linear electron-positron collider, an electron-proton collider in the LEP/LHC tunnel, a muon collider and a future larger hadron collider (FLHC). The Higgs boson and supersymmetry are used as benchmarks for assessing their capabilities. The LHC has great capacities for precision measurements as well as exploration, but also shortcomings where the complementary strengths of a linear electron-positron collider would be invaluable. It is not too soon to study seriously possible subsequent colliders.

  13. Prospects for future climate

    International Nuclear Information System (INIS)

    Anon.

    1990-01-01

    The different climates of the past and model simulations of future climates convincingly indicate that the continuing emissions of greenhouse gases will lead to significant global warming and to changes in precipitation and other climatic variables. The projected changes in atmospheric composition and, consequently, in climatic conditions will be unique and more rapid than at any time in the past. The developing understanding of the chemical cycles controlling atmospheric composition and of the processes and behavior controlling the climate system can provide significant guidance about how the future climate will change. This chapter first summarizes the many scientific advances described in the preceding chapters that can help one better understand and describe the climate system and the resulting agricultural and hydrological impacts of these changes in climate. The chapter then draws from this understanding to outline the prospects for future climate

    Full Text Available The purpose of this study is to discuss the current state and future of auditing. Expert consensus is used as a basis to examine the current state of auditing and generate modifications both needed and likely to occur in the audit profession. This study contributes to the literature by using the Delphi method to develop predictions as to the direction of the audit industry and discuss the implications associated with these predictions. If auditors can better understand where the profession stands and where it is headed, then they can better prepare for the future. Some predictions emerging from this study relative to future audit practices include increasing automation of audit procedures, more predictive financial statements, continuous auditing of financial statements and transactions, and an increasingly global perspective regarding audit activities.

    Full Text Available Current ongoing societal processes allow me to say that all humanity must foresee the great opportunity to change direction from market driven development to human scale sustainable development as the only way to achieve whole scale growth. In the achievement of this transition the most important observation is that it could be achieved without miraculous technologies or drastic transformations of human societies. The main requirement is the translation of basic knowledge to the people, especially in less developed countries and to the younger generations. Without sincere political will our common future cannot be reached. In my essay I tried to demonstrate what may happen in the future, if the no-dialogue community develops. Sustainable development is the only correct route if we want to get where we are going – the future well being of all human kind.

  16. (Nuclear) energy policy in future

    1982-01-01

    With this report the German Federal Diet submits the final results of the opinion-forming and decision-making process concerning the recommendations made by the investigation committee 'Future Nuclear Energy Policy' in June 1980. By means of this report it is intended to point out to an interested public the difficult and time-consuming process of parliamentary decision-making. This report is also to be seen as the final opinion delivered on the recommendations made by the investigation committee. The recommendations were to continue to pursue the peaceful use of nuclear energy, the necessity and technical justifiability of which had basically been approved by all parliamentary groups. In view of the import of the subject and in recognition of the work done by the investigation committee, the German Parliament has thoroughly discussed the report and has reviewed the analyses and recommendations in conjunction with other political fields to be considered. One part of the recommendations was taken up almost unanimously. As far as the safety of nuclear installations is concerned, the investigation committee could not submit any new findings which would give reasons for modifying the hitherto positive assessment of the safety of nuclear installations. The recommendations of the investigation committee mainly referred to the decision-making process in the field of energy policy which will effect the next decade. What fundamental decisions are to be made until when was pointed out as well as the findings and experience to be made until then. (orig./HP) [de

    This report documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain, Nevada, the site of a repository for spent nuclear fuel and high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this report provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the following reports: ''Simulation of Net Infiltration for Present-Day and Potential Future Climates'' (BSC 2004 [DIRS 170007]), ''Total System Performance Assessment (TSPA) Model/Analysis for the License Application'' (BSC 2004 [DIRS 168504]), ''Features, Events, and Processes in UZ Flow and Transport'' (BSC 2004 [DIRS 170012]), and ''Features, Events, and Processes in SZ Flow and Transport'' (BSC 2004 [DIRS 170013]). Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one available forecasting method for establishing upper and lower bounds for future climate estimates. The selection of different methods is directly dependent on the available evidence used to build a forecasting argument. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. While alternative analyses are possible for the case presented for Yucca Mountain, the evidence (data) used would be the same and the conclusions would not be expected to drastically change. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog. Other alternative

    Full Text Available In this paper, we present an incentivized experiment to investigate the degree of loss aversion when people make decisions for their current selves and future selves under risk. We find that when participants make decisions for their future selves, they are less loss averse compared to when they make decisions for their current selves. This finding is consistent with the interpretation of loss aversion as a bias in decision-making driven by emotions, which are reduced when making decisions for future selves. Our findings endorsed the external validity of previous studies on the impact of emotion on loss aversion in a real world decision-making environment.

  9. The future(s) of emission allowances

    International Nuclear Information System (INIS)

    Rosenzweig, K.M.; Villarreal, J.A.

    1993-01-01

    The Clean Air Act Amendments of 1990 (CAAA) established a sulfur dioxide emission allowance system to be implemented by the US Environmental Protection Agency (EPA). Under the two-phase implementation of the program, electric utilities responsible for approximately 70 percent of SO 2 emissions in the United States will be issued emission allowances, each representing authorization to emit one ton of sulfur dioxide during a specified calendar year or a later year. Allowances will be issued to utilities with electric-generating units affected by the CAAA limits, as well as to certain entities which may choose to opt-in to the program. Each utility or other emission source must hold a number of allowances at least equal to its total SO 2 emissions during any given year. Unused allowances may be sold, traded, or held in inventory for use against SO 2 emissions in future years. Anyone can buy and hold allowances, including affected utilities, non-utility companies, SO 2 allowances brokers and dealers, environmental groups, and individuals. During Phase I of the program, allowances equivalent to approximately 6.4 million tons of SO 2 emissions will be allocated annually to a group of 110 large, high-SO 2 -emitting power plants. In Phase II, virtually all power-generating utilities (representing approximately 99.4 percent of total US utility emissions) will be subject to the program. The number of allowances issued will increase to approximately 8.9 million a year, with certain special allocations raising the actual number issued to 9.48 million between the years 2000 to 2009, and 8.95 million yearly thereafter. Thus, the CAAA goal of annual emissions of 9 million tons should be achieved by 2010, when virtually all US emission sources will be participating in the program

    Information is one of the most powerful tools available today. All advances in technology may be used, as David Sarnoff said, for the benefit or harm of society. Information can be used to shape the future by free people, or used to control people by less than benevolent governments, as has been demonstrated since the mid - 1930s, and with growing frequency over the past 50 years. What promised to once set people free and fuel an industrial revolution that might improve the standard of living over most of the world, has also been used to manipulate and enslave entire populations. The future of information is tied to the future of technologies that support the collection of data, processing those data into information and knowledge, and distribution. Technologies supporting the future of information must include technologies that help protect the integrity of data and information, and help to guarantee its discoverability and appropriate availability -- often to the whole of society.

  17. Future Climate Analysis

    Energy Technology Data Exchange (ETDEWEB)

    James Houseworth

    2001-10-12

    This Analysis/Model Report (AMR) documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain (YM), Nevada (Figure 1), the site of a potential repository for high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this AMR provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the infiltration model (USGS 2000) and for the total system performance assessment for the Site Recommendation (TSPA-SR) at YM. Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one method, among many, of establishing upper and lower bounds for future climate estimates. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog. Revision 00 of this AMR was prepared in accordance with the ''Work Direction and Planning Document for Future Climate Analysis'' (Peterman 1999) under Interagency Agreement DE-AI08-97NV12033 with the U.S. Department of Energy (DOE). The planning document for the technical scope, content, and management of ICN 01 of this AMR is the ''Technical Work Plan for Unsaturated Zone (UZ) Flow and Transport Process Model Report'' (BSC 2001a). The scope for the TBV resolution actions in this ICN is described in the ''Technical Work Plan for: Integrated Management of Technical

  18. Future carbon regulations and current investments in alternative coal-fired power plant technologies

    International Nuclear Information System (INIS)

    Sekar, Ram C.; Parsons, John E.; Herzog, Howard J.; Jacoby, Henry D.

    2007-01-01

    We analyze how uncertain future US carbon regulations shape the current choice of the type of power plant to build. Our focus is on two coal-fired technologies, pulverized coal (PC) and integrated coal gasification combined cycle technology (IGCC). The PC technology is cheapest-assuming there is no need to control carbon emissions. The IGCC technology may be cheaper if carbon must be captured. Since power plants last many years and future regulations are uncertain, a US electric utility faces a standard decision under uncertainty. A company will confront the range of possible outcomes, assigning its best estimate of the probability of each scenario, averaging the results and determining the power plant technology with the lowest possible cost inclusive of expected future carbon related costs, whether those costs be in the form of emissions charges paid or capital expenditures for retrofitting to capture carbon. If the company assigns high probability to no regulation or to less stringent regulation of carbon, then it makes sense for it to build the PC plant. But if it assigns sufficient probability to scenarios with more stringent regulation, then the IGCC technology is warranted. We provide some useful benchmarks for possible future regulation and show how these relate back to the relative costs of the two technologies and the optimal technology choice. Few of the policy proposals widely referenced in the public discussion warrant the choice of the IGCC technology. Instead, the PC technology remains the least costly. However, recent carbon prices in the European Emissions Trading System are higher than these benchmarks. If it is any guide to possible future penalties for emissions in the US, then current investment in the IGCC technology is warranted. Of course, other factors need to be factored into the decision as well

  19. The future of PACS

    International Nuclear Information System (INIS)

    Nagy, Paul G.

    2007-01-01

    How will the future of picture archiving and communication systems (PACS) look, and how will this future affect the practice of radiology? We are currently experiencing disruptive innovations that will force an architectural redesign, making the majority of today’s commercial PACS obsolete as the field matures and expands to include imaging throughout the medical enterprise. The common architecture used for PACS cannot handle the massive amounts of data being generated by even current versions of computed tomography and magnetic resonance scanners. If a PACS cannot handle today’s technology, what will happen as the field expands to encompass pathology imaging, cone-beam reconstruction, and multispectral imaging? The ability of these new technologies to enhance research and clinical care will be impaired if PACS architectures are not prepared to support them. In attempting a structured approach to predictions about the future of PACS, we offer projections about the technologies underlying PACS as well as the evolution of standards development and the changing needs of a broad range of medical imaging. Simplified models of the history of the PACS industry are mined for the assumptions they provide about future innovations and trends. The physicist frequently participates in or directs technical assessments for medical equipment, and many physicists have extended these activities to include imaging informatics. It is hoped that by applying these speculative but experienced-based predictions, the interested medical physicist will be better able to take the lead in setting information technology strategies that will help facilities not only prepare for the future but continue to enjoy the benefits of technological innovations without disruptive, expensive, and unexpected changes in architecture. A good PACS strategy can help accelerate the time required for innovations to go from the drawing board to clinical implementation.

This is especially true for the use of the theory in making predictions about future disruptions. In order to continue to develop a valuable theory of disruption, we...... find it useful to first review what the theory of disruptive innovation initially was, how it has developed, and where we are now. A cross section of disruptive innovation literature has been reviewed in order to form a general foundation from which we might better understand the changing world...

  1. Future Tense and Economic Decisions: Controlling for Cultural Evolution.

    Science.gov (United States)

    Roberts, Seán G; Winters, James; Chen, Keith

    2015-01-01

    A previous study by Chen demonstrates a correlation between languages that grammatically mark future events and their speakers' propensity to save, even after controlling for numerous economic and demographic factors. The implication is that languages which grammatically distinguish the present and the future may bias their speakers to distinguish them psychologically, leading to less future-oriented decision making. However, Chen's original analysis assumed languages are independent. This neglects the fact that languages are related, causing correlations to appear stronger than is warranted (Galton's problem). In this paper, we test the robustness of Chen's correlations to corrections for the geographic and historical relatedness of languages. While the question seems simple, the answer is complex. In general, the statistical correlation between the two variables is weaker when controlling for relatedness. When applying the strictest tests for relatedness, and when data is not aggregated across individuals, the correlation is not significant. However, the correlation did remain reasonably robust under a number of tests. We argue that any claims of synchronic patterns between cultural variables should be tested for spurious correlations, with the kinds of approaches used in this paper. However, experiments or case-studies would be more fruitful avenues for future research on this specific topic, rather than further large-scale cross-cultural correlational studies.

    This paper investigates the information content of futures option prices when the futures price is regulated while the futures option price itself is not. The New York Board of Trade provides the empirical setting for this type of dichotomy in regulation. Most commodity derivatives markets regulate prices of all derivatives on a particular commodity simultaneously. NYBOT has taken an almost unique position by imposing daily price limits on their futures contracts while leaving the options pri...

    2001-01-01

    The article discusses not only the future of energy and resource consumption in various areas of the world, but also its development over the centuries since the industrial revolution. The present situation, with large discrepancies between the energy consumption of industrialised nations and the developing countries is examined. Social and environmental aspects are discussed and the sustainable use of the Earth's resources and the inconsistencies in this area is looked at. Rather than adopting a moralistic approach, the article appeals to man's powers of innovation and sense of responsibility in order to develop solutions to today's and future energy supply problems. The article is richly illustrated with diagrams and graphs on world energy and social statistics

    2015-01-01

    Full Text Available A ′need-supply′ and ′requirement-distribution mismatch′ along with a continuingneed explosion are the biggest hurdles faced by palliative medicine today. It is the need of the hour to provide an unbiased, equitable and evidence-based palliative care to those in need irrespective of the diagnosis, prognosis, social and economic status or geographical location. Palliative care as a fundamental human right, ensuring provision throughout the illness spectrum, global as well as region-specific capacity building, uniform availability of essential drugs at an affordable price, a multidisciplinary team approachand caregiver-support are some of the achievable goals for the future. This supplanted with a strong political commitment, professional dedication and ′public-private partnerships′ are necessaryto tackle the existing hurdles and the exponentially increasing future need. For effectively going ahead it is of utmost importance to integrate palliative medicine into medical education, healthcare system and societal framework.

    A group of physicists present their discipline to the general public in an entirely new way. They do not expose the results of physics like established dogmas, on the contrary they describe the questions that remain open and that might be solved in a more or less distant future. These questions are the most fundamental that one can pose: the origin of the Big-bang, the future of the universe, the existence of the Higgs boson, the true nature of the core of the earth, superconductivity, the new quantum revolution which may upset all the computer industry, the modeling of climate, or the physics of soft matter that invades our watches, our screens of computers or television sets. The 14 chapters of this book are 14 journeys to the borders of today's knowledge. (A.C.)

    1991-06-01

    Pregeometry is a theory, first suggested by Sakharov in 1967, in which gravity is taken as a quantum effect of matter fields and in which Einstein's theory of general relativity for gravity appears as an approximate and effective theory at long distances. It is shown by reviewing the extensive developments of pregeometric theories of gravity for the last more than a decade that the original idea by Sakharov is really working. Many future prospects of the theories are discussed in some detail. (author)

    The book includes an introduction then it speaks about the options to secure sources of energy, nuclear power option, nuclear plants to generate energy including light-water reactors (LWR), heavy-water reactors (HWR), advanced gas-cooled reactors (AGR), fast breeder reactors (FBR), development in the manufacture of reactors, fuel, uranium in the world, current status of nuclear power generation, economics of nuclear power, nuclear power and the environment and nuclear power in the Arab world. A conclusion at the end of the book suggests the increasing demand for energy in the industrialized countries and in a number of countries that enjoy special and economic growth such as China and India pushes the world to search for different energy sources to insure the urgent need for current and anticipated demand in the near and long-term future in light of pessimistic and optimistic outlook for energy in the future. This means that states do a scientific and objective analysis of the currently available data for the springboard to future plans to secure the energy required to support economy and welfare insurance.

  18. Toward sustainable energy futures

    Energy Technology Data Exchange (ETDEWEB)

    Pasztor, J. (United Nations Environment Programme, Nairobi (Kenya))

    1990-01-01

    All energy systems have adverse as well as beneficial impacts on the environment. They vary in quality, quantity, in time and in space. Environmentally sensitive energy management tries to minimize the adverse impacts in an equitable manner between different groups in the most cost-effective ways. Many of the enviornmental impacts of energy continue to be externalized. Consequently, these energy systems which can externalize their impacts more easily are favoured, while others remain relatively expensive. The lack of full integration of environmental factors into energy policy and planning is the overriding problem to be resolved before a transition towards sustainable energy futures can take place. The most pressing problem in the developing countries relates to the unsustainable and inefficient use of biomass resources, while in the industrialized countries, the major energy-environment problems arise out of the continued intensive use of fossil fuel resources. Both of these resource issues have their role to play in climate change. Although there has been considerable improvement in pollution control in a number of situations, most of the adverse impacts will undoubtedly increase in the future. Population growth will lead to increased demand, and there will also be greater use of lower grade fuels. Climate change and the crisis in the biomass resource base in the developing countries are the most critical energy-environment issues to be resolved in the immediate future. In both cases, international cooperation is an essential requirement for successful resolution. 26 refs.

  19. The future petroleum geologist

    International Nuclear Information System (INIS)

    Berg, R.R.

    1992-01-01

    This paper reports that in July 1985, AAPG President William L. Fisher appointed a select committee to determine the capabilities that will be required of petroleum geologists in the future. His charge to the committee was based on the profound changes and uncertainties that were beginning to be felt in the industry and would surely affect the employment of geologists and their professional practice. These changes are well known: the supply of oil had exceeded demand, the price of oil was unstable, many companies were threatened by debt and buy-outs, and corporate restructuring was underway to meet changing economic conditions. All contributed to great uncertainty about the need and requirements of geological employment and practice. Specifically, President Fisher charged the committee to distinguish those elements of recent times that are cyclic and those that are long-term in their effects; to characterize the state of the industry for the next 25 years; to predict the capabilities that the future petroleum geologist should posses to meet the challenges of the future; and most importantly, the define the role of AAPG and its commitments to the membership under these changing conditions

    The Danish Government's plan ''Our Future Energy'' seeks to create green growth and help the country convert to 100 percent renewable energy use by 2050. The Danish Government in November 2011 presented its plan for how the country can secure its energy future. Titled ''Our Future Energy'', the strategy presents specific measures for fulfilling the Government's goal of stimulating green growth. The plan is based on the previous government's Energy Strategy 2050, but raises the bar higher. The long-term goal of the plan is to implement an energy and transport network that relies solely on renewable energy sources. By 2020, the initiatives will lead to extensive reductions in energy consumption, making it possible for half of the country's electricity consumption to be covered by wind power. Coal is to be phased out of Danish power plants by 2030. And by 2035, all electricity and heating will be generated using renewable sources. (Author)

  1. Site investigations for the disposal of spent fuel - investigation program

    1985-11-01

    The Industrial Power Company Ltd (TVO) is making preparations for the final disposal of spent nuclear fuel into the Finnish bedrock. The revised site investigation program for the years 1986-2010 is presented in this report. The objectives and activities in the near future are described in more detail. The main objectives and frame programs for the investigations in the more distant future are described. The program planning of these investigations are being developed in the preceding site investigations. The investigations for the site selection are divided into four phases: 1983-1985 selection of the investigation areas, preparations for the field investigations, drilling and investigations in a deep test borehole; 1986-1992 preliminary site investigations in 5-10 investigation areas; 1993-2000 detailed site investigations in 2-3 investigation areas. Site selection in the year 2000; 2001-2010 complementary investigations on the selected site. The first investigation phase will be carried out as planned. In this phase a 1001 m deep test borehole was drilled at Lavia in western Finland. With the investigations in the borehole and related development work, preparations were made for the future field investigations. The equipment and investigation methods are being developed during the site investigations. The equipment for taking groundwater samples and the unit for hydraulic testing have been developed. In the future the emphasis in the work will be in developing equipment for monitoring of the hydraulic head and measuring the volumetric flow. In groundwater sampling the present procedure can be improved by adding the test for the in-situ measurements. The results of the field investigations will be stored and processed in a centralized data base. The data base will transmit the results for the interpretation and then the interpreted results transmitted for model calculations and reporting. The cost estimate for the investigations in 1986-2010 is 110-125 million

The results and recommendations presented in this report are generally independent of future land-use scenarios. An LFI report is required when waste sites are to be considered for IRM and existing data are insufficient to formulate a conceptual model or perform a QRA. The purpose of the report is to identify those sites that are recommended to remain as candidates for IRM, provide a preliminary summary of site characterization studies, refine the conceptual model as needed, identify potential contaminant and location-specific applicable or relevant and appropriate requirements (ARAR), and provide a qualitative assessment of the risks associated with the sites. This assessment includes consideration of whether contaminant concentrations pose a risk to human health or the environment that warrants action through IRM. Seven sites were intrusively investigated: 1322-N, 116-N-2, 119-N, 120-N-2, 120-N-1, South Settling Pond, and the 166-N Tank Farm (UN-100-N-17) unplanned release at the 166-N Tank Farm. Vadose zone sediments from these sites were sampled and analyzed. Radiological contamination is the primary concern as confirmed through this study

    A literature survey has been conducted to assess the future world supply of, and demand for, titanium, copper and lead. These metals are candidates for the fabrication of containers for the immobilization and disposal of Canada's nuclear used-fuel in an underground disposal vault at a Used-Fuel Disposal Centre. The Centre is assumed to begin operation by the year 2020 and continue for about 40 years. The survey has shown that the world has abundant supplies of titanium minerals (mostly in the form of ilmenite), which are expected to last up to at least 2110. However, for copper and lead, the balance between supply and demand may warrant increased monitoring beyond the year 2000. A number of factors that can influence supply and demand are discussed

    In the near future, fundamental interactions at high-energy scales may be most efficiently studied via precision measurements at low energies. A universal language to assemble and interpret precision measurements is the so-called SMEFT, which is an effective field theory (EFT) where the Standard Model (SM) Lagrangian is extended by higher-dimensional operators. In this paper we investigate the possible impact of the DUNE neutrino experiment on constraining the SMEFT. The unprecedented neutrino flux offers an opportunity to greatly improve the current limits via precision measurements of the trident production and neutrino scattering off electrons and nuclei in the DUNE near detector. We quantify the DUNE sensitivity to dimension-6 operators in the SMEFT Lagrangian, and find that in some cases operators suppressed by an O(30) TeV scale can be probed. We also compare the DUNE reach to that of future experiments involving atomic parity violation and polarization asymmetry in electron scattering, which are sensitive to an overlapping set of SMEFT parameters.

    Full Text Available This article investigates the process of transition from the Millennium Development Goals to Sustainable Development Goals (SDGs. The authors have set an objective to demonstrate that SD as a future form of development of civilization from the very beginning had a “target orientation” and from the beginning and anticipated realization and staging of the whole hierarchy of objectives needed for the establishment of an effective global governance. In the future, global development in its “anthropogenic” aspect will be to implement the goals and principles of SD, which will be updated with each new stage of the implementation of this kind of socio-natural evolution. The paper argues the position that the concept of SD should be radically transformed into a “global dimension.” Attention is drawn to the fact that Russia recognized another distant, but very important in the conceptual and theoretical perspective, global goal of “sustainable transition” — formation of the noosphere.

    The runway is universally acknowledged as a constraining factor to capacity in the National Airspace System (NAS). It follows that investigation of the effective use of runways, both in terms of selection and assignment, is paramount to the efficiency of future NAS operations. The need to address runway management is not a new idea; however, as the complexities of factors affecting runway selection and usage increase, the need for effective research in this area correspondingly increases. Under the National Aeronautics and Space Administration s Airspace Systems Program, runway management is a key research area. To address a future NAS which promises to be a complex landscape of factors and competing interests among users and operators, effective runway management strategies and capabilities are required. This effort has evolved from an assessment of current practices, an understanding of research activities addressing surface and airspace operations, traffic flow management enhancements, among others. This work has yielded significant progress. Systems analysis work indicates that the value of System Oriented Runway Management tools is significantly increased in the metroplex environment over that of the single airport case. Algorithms have been developed to provide runway configuration recommendations for a single airport with multiple runways. A benefits analysis has been conducted that indicates the SORM benefits include supporting traffic growth, cost reduction as a result of system efficiency, NAS optimization from metroplex operations, fairness in aircraft operations, and rational decision making.

    Abstract This article presents findings from a survey conducted by RAND Europe at the request of the National Institute for Health Research (NIHR) to gather and synthesise stakeholder views on the future of health and healthcare in England in 20 to 30 years' time. The aim of the research was to generate an evidenced-based picture of the future health and healthcare needs, and how it might differ from today, in order to inform strategic discussions about the future priorities of the NIHR and the health and social care research communities more broadly. The survey provided a rich and varied dataset based on responses from 300 stakeholders in total. A wide range of fields were represented, including public health, social care, primary care, cancer, genomics, mental health, geriatrics, child health, patient advocacy and health policy. The respondent group also included a number of professional and private stakeholder categories, such as clinicians, policy experts, academics and patient and public representatives. The study findings validate a number of prominent health research priorities currently visible in England, such as antimicrobial resistance, the burden of dementia and age-related multi-morbidity, digital health and genomics. Interest in these areas and other themes, such as mental health, health inequalities and transforming health service models, cut across multiple disciplinary boundaries. However, it is clear that there are a variety of views among stakeholders on the relative importance of these areas of focus, and the best approach to manage their emergence in the coming decades. The full dataset of survey responses, for which permission to share was given, is a useful resource for those seeking to engage with a particular issue in more depth. The dataset can be found on NIHR's website at: http://nihr.ac.uk/news-and-events/documents/quotes.xls. PMID:29607245

  11. Printing Has a Future

    Full Text Available Printing will also be done in the future. Printed items meet basic needs and are deeply anchored in people’s habits. Being able to handle and collect printed matter is highly attractive. And paper is now more alive than ever. It is therefore too shortsighted to disclaim the importance of one of the still large economic sectors just because of a few looming-recession instigated market shifts.The exciting aspect of drupa 2004 is: printing will be reinvented, so to speak. Much more printing will be done in the future than at present. On the one hand, people are concentrating on process optimization and automation to ensure this. Measuring and testing, process control and optimization, and linking up "office software" with printing technology will be very central topics at drupa 2004. Electronics and print are not rivals; a symbiosis exists. And printing is high-tech: hardly any other multifaceted sector which has been so successful for centuries is as computerized as the printing industry.A series of "new chapters" in the variety of printing possibilities will be opened at drupa. Talk will be generated by further technical developments, often the connection between paper/cardboard and electronics, the link between the office world and graphics industry, text databases and their link-up to graphic page production tools, and "on the fly" dynamic printing over networks.All of this and more belongs to future potentialities, which are so substantial overall, the outlook is by no means black for the "black art". Like its predecessors, drupa 2004 is also a product trade fair. However, more than ever before in its history, it is also an "information village". The exhibits are useful, because they occasionally make what this means visible.

    At the COSY cooler synchrotron several experimental facilities are in operation at internal and external target stations. The combination of a high quality low emittance proton beam with high acceptance detector systems allows precise and kinematically complete experiments. The momentum range of the COSY beam from 300 MeV/c up to about 3.5 GeV/c opens a large field of experimental studies. Data have been taken in various reaction channels from elementary p-p interactions up to reactions on complex target nuclei resulting in a data base of high precision. These studies will be continued and extended to more detailed investigations in the future. Differential cross section distributions also for more than two body reactions will be extracted. By controlling the isospin and spin degrees of freedom the complexity will be reduced. Of specific interest are channels with strangeness. (orig.)

    2013-01-01

    Biliary stenting has evolved dramatically over the past 30 years. Advancements in stent design have led to prolonged patency and improved efficacy. However, biliary stenting is still affected by occlusion, migration, anatomical difficulties, and the need for repeat procedures. Multiple novel plastic biliary stent designs have recently been introduced with the primary goals of reduced migration and improved ease of placement. Self-expandable bioabsorbable stents are currently being investigated in animal models. Although not US Food and Drug Administration approved for benign disease, fully covered self-expandable metal stents are increasingly being used in a variety of benign biliary conditions. In malignant disease, developments are being made to improve ease of placement and stent patency for both hilar and distal biliary strictures. The purpose of this review is to describe recent developments and future directions of biliary stenting. PMID:23837001

    Context Delirium is a highly prevalent complication in patients in palliative care settings, especially in the end-of-life context. Objectives To review the current evidence base for treating episodes of delirium in palliative care settings and propose a framework for future development. Methods We combined multidisciplinary input from delirium researchers and other purposely selected stakeholders at an international delirium study planning meeting. This was supplemented by a literature search of multiple databases and relevant reference lists to identify studies regarding therapeutic interventions for delirium. Results The context of delirium management in palliative care is highly variable. The standard management of a delirium episode includes the investigation of precipitating and aggravating factors followed by symptomatic treatment with drug therapy. However, the intensity of this management depends on illness trajectory and goals of care in addition to the local availability of both investigative modalities and therapeutic interventions. Pharmacologically, haloperidol remains the practice standard by consensus for symptomatic control. Dosing schedules are derived from expert opinion and various clinical practice guidelines as evidence-based data from palliative care settings are limited. The commonly used pharmacologic interventions for delirium in this population warrant evaluation in clinical trials to examine dosing and titration regimens, different routes of administration, and safety and efficacy compared with placebo. Conclusion Delirium treatment is multidimensional and includes the identification of precipitating and aggravating factors. For symptomatic management, haloperidol remains the practice standard. Further high-quality collaborative research investigating the appropriate treatment of this complex syndrome is needed. PMID:24480529

    The aim of this picture-based book is to make climate change understandable to a wider public. Images tell the story, figure captions enhance the essentials. Text passages tie and highlight the story, rather than provide long explanations of complex scientific reasoning. Brief summaries at the end of each chapter review knowledge of which everybody should be aware. They are based on the scientific assessments of the 1990 Intergovernmental Panel on Climate Change Report. The climate story is explored from six different angles: the physical system, past changes, how climate affects cultures, how people affect climate, the importance of research and how to view the future

    As the nuclear industry arrives at a crossroads, this paper looks at BNFL's nuclear future. It does this by addressing two key issues: the energy balance and regulation. The first issue takes in the problems of climate change and renewables, and the nuclear contribution. The second issue raises the possibility that, although safety is the top priority for BNFL, the cost of regulation may be becoming disproportionate to the advantages gained. The paper concludes that the balancing act between energy supply and CO 2 reduction can only be achieved successfully if nuclear is a significant part of the equation. (author)

    2016-02-01

    Testicular cancer commonly affects men in the prime of their lives. While survival rates are excellent, little previous research has examined men's experiences of adjustment to survivorship. We aimed to explore this issue in younger testicular cancer survivors. In-depth qualitative interviews were conducted with testicular cancer survivors over two time points approximately 6 months apart in the year following treatment completion. Interviews were analysed using a grounded theory approach. The sample included 18 testicular cancer survivors between 22 and 44 years (mean age 34). A grounded theory was developed, which explained the process of positive adjustment over the first year following the treatment completion in terms of men's ability to dismantle the present and future threats of cancer, involving the key transitions of gaining a sense of perspective and striving to get on with life and restore normality. These were facilitated by six key processes. The processes that explained a negative adjustment trajectory are also presented. These findings contribute to the understanding of the psychosocial impact of testicular cancer on younger men's lives and have implications for the provision of support to testicular cancer survivors. Further investigation into the feasibility of one-on-one peer support interventions is warranted, as well as informal support that respects men's desire for independence. Understanding the processes involved in adjustment highlights ways in which health professionals can offer support to those struggling to adjust through challenging illness beliefs, encouraging emotional disclosure and facilitating peer mentoring.

    Geiser, Achim

    2015-12-01

    A variety of possible future analyses of HERA data in the context of the HERA data preservation programme is collected, motivated, and commented. The focus is placed on possible future analyses of the existing ep collider data and their physics scope. Comparisons to the original scope of the HERA pro- gramme are made, and cross references to topics also covered by other participants of the workshop are given. This includes topics on QCD, proton structure, diffraction, jets, hadronic final states, heavy flavours, electroweak physics, and the application of related theory and phenomenology topics like NNLO QCD calculations, low-x related models, nonperturbative QCD aspects, and electroweak radiative corrections. Synergies with other collider programmes are also addressed. In summary, the range of physics topics which can still be uniquely covered using the existing data is very broad and of considerable physics interest, often matching the interest of results from colliders currently in operation. Due to well-established data and MC sets, calibrations, and analysis procedures the manpower and expertise needed for a particular analysis is often very much smaller than that needed for an ongoing experiment. Since centrally funded manpower to carry out such analyses is not available any longer, this contribution not only targets experienced self-funded experimentalists, but also theorists and master-level students who might wish to carry out such an analysis.

  19. Our Future in Space

    Impey, Chris David

    2017-06-01

    The Space Age is half a century old. Its early successes were driven by a fierce superpower rivalry between the Soviet Union and the United States, which tended to obscure the fact that exploration and risk-taking is built into human DNA. Decades after we last set foot on the Moon, and years after the Space Shuttle was retired, the space activity is finally leaving the doldrums. A vibrant private sector led by SpaceX, Blue Origins, and Virgin Galactic plans to launch supplies cheaply into Earth orbit and give anyone the chance of a sub-orbital joy ride. New materials are being developed that could lead to space elevators and transform the economics of space travel. Fighting gravity will always be difficult but engineers are rethinking rockets and developing new propulsion technologies. Permanent bases on the Moon and Mars are now within reach, and a new Space Race is brewing, with China ascendant. Medical advances might even allow us to reach for the stars. The talk will review the history and landmarks of the international space program, give a snapshot of the current dynamic situation, and plot the trajectory of the future of space travel. The time has come to envision our future off-Earth.

  20. Future climate. Engineering solutions

    Energy Technology Data Exchange (ETDEWEB)

    Ferdinand, J.F.; Hagedorn-Rasmussen, P.; Fonnesbech, B.

    2009-09-15

    Future Climate Engineering Solutions - Joint Report is the common output and a documentation of more than 1 year's effort by 13 engineering associations - in 12 countries - to demonstrate how technologies can combat climate change. The report consists of three parts: Summaries of 10 national climate plans and technology prospects, 5 Key Common Findings, and a Climate Call from Engineers to create a new global climate treaty. The basic assumption of the project is recognition that GHG emissions, and their concentration in the atmosphere, must be reduced to a sustainable level. The project definition of a sustainable level is equivalent to the best-case stabilisation scenario which was presented in the 4th Assessment Report (AR4) by the UN Intergovernmental Panel on Climate Change (IPCC), whereby the global mean temperature is most likely to stabilise at 2.0-2.4 deg. C. The Future Climate website www.futureclimate.info holds more information about the project, including possibility to download project material, including the full national climate plans.

    1998-09-01

    The Ocean, Our Future is the official report of the Independent World Commission on the Oceans, chaired by Mário Soares, former President of Portugal. Its aim is to summarize the very real problems affecting the ocean and its future management, and to provide imaginative solutions to these various and interlocking problems. The oceans have traditionally been taken for granted as a source of wealth, opportunity and abundance. Our growing understanding of the oceans has fundamentally changed this perception. We now know that in some areas, abundance is giving way to real scarcity, resulting in severe conflicts. Territorial disputes that threaten peace and security, disruptions to global climate, overfishing, habitat destruction, species extinction, indiscriminate trawling, pollution, the dumping of hazardous and toxic wastes, piracy, terrorism, illegal trafficking and the destruction of coastal communities are among the problems that today form an integral part of the unfolding drama of the oceans. Based on the deliberations, experience and input of more than 100 specialists from around the world, this timely volume provides a powerful overview of the state of our water world.

  2. Future of fusion implementation

    Beardsworth, E.; Powell, J.R.

    1978-01-01

    For fusion to become available for commercial use in the 21st century, R and D must be undertaken now. But it is hard to justify these expenditures with a cost/benefit oriented assessment methodology, because of both the time-frame and the uncertainty of the future benefits. Focusing on the factors most relevant for current consideration of fusion's commercial prospects, i.e., consumption levels and the outcomes for fission, solar, and coal, many possible futures of the US energy system are posited and analyzed under various assumptions about costs. The Reference Energy System approach was modified to establish both an appropriate degree of detail and explicit time dependence, and a computer code used to organize the relevant data and to perform calculations of system cost (annual and discounted present value), resource use, and residuals that are implied by the consumptions levels and technology mix in each scenario. Not unreasonable scenarios indicate benefits in the form of direct cost savings, which may well exceed R and D costs, which could be attributed to the implementation of fusion

    2005-01-01

    Astrobiology, a new exciting interdisciplinary research field, seeks to unravel the origin and evolution of life wherever it might exist in the Universe. The current view of the origin of life on Earth is that it is strongly connected to the origin and evolution of our planet and, indeed, of the Universe as a whole. We are fortunate to be living in an era where centuries of speculation about the two ancient and fundamental problems: the origin of life and its prevalence in the Universe are being replaced by experimental science. The subject of Astrobiology can be approached from many different perspectives. This book is focused on abiogenic organic matter from the viewpoint of astronomy and planetary science and considers its potential relevance to the origins of life on Earth and elsewhere. Guided by the review papers in this book, the concluding chapter aims to identify key questions to motivate future research and stimulate astrobiological applications of current and future research facilities and space mi...

  4. Future applications of heterostructures

    Science.gov (United States)

    König, Ulf

    1996-01-01

    In this review the status and future of heterostructure devices is discussed. The author concentrates on III/V and Si/SiGe. Performance and applications are folded to the data and expectations of the micro- and opto-electronic market and to the traditional Si-mainstream. New trends, i.e. the SIA-roadmap, are checked how heterodevices can fit in. Only the most attractive candidates for applications are considered, i.e. the heterobipolar-, the hetero field effect-transistors, the resonant tunnel diode and to a less extent, some optoelectronic devices. Considered figures of merit are frequencies, transconductance, noise at high and low frequencies, threshold voltage, power delay, threshold current and quantum efficiencies. It is pointed out how to optimize those by material and design. Extrapolations to the future potential of heterodevices are made, just taking the claimed scaling of lateral dimensions into consideration. Field of applications are presented, where heterodevices offer exclusive qualities, i.e. high frequency transmission and sensors, and new mixed systems. In the case of logic the trend goes to nanoscaled devices and ICs targeting nanoelectronics beyond traditional electronics. Heterostructure layers allow a vertical nanoscaling and thus give an additional degree of freedom for designing and optimation. It is an attractive challenge for scientists and engineers to solve the related technological problems like thin, low thermal budget oxides, like defect free buffer layers etc. Special attention is put on Si/SiGe, which is now on an upswing in electronics and photonics.

  5. The future since Chernobyl

    Warnock, Mary.

    1986-01-01

    The author reviews three books about energy policy, particularly in relation to nuclear energy. From these, which were all published before the Chernobyl disaster, the reviewer identifies two main problems relating to nuclear energy - immediate safety and disposal of nuclear waste. Risk analysis is seen as unhelpful in allaying public fears as it is the nature of the risk of nuclear accidents, rather than its numerical probability, that is frightening. A paper on the assessment of Best Practical Environmental Options (BPEO) for management of low and intermediate-level solid radioactive waste, is referred to when commenting on nuclear waste disposal. Ordinary people have two political obligations with respect to nuclear energy - first to demand knowledge and examine further reassuring information. Risks taken will then be taken with proper information obtained first. Secondly, to look beyond the short-term consequences of a nuclear programme. To fulfill these obligations policy-makers have to be educated to be open and honest about the nuclear future and to be seen to be looking further ahead than the immediate future. (U.K.)

    1987-09-01

    The analysis of the radar and seismic data has given a consistent description of the fracture zones at the Crosshole site in agreement with geological and other geophysical observations made in the boreholes. The hydraulic investigations within the Crosshole project have yielded substantial progress in assessing the hydrogeology of fractured granitic rocks. The crosshole hydraulic testing concentrated on measuring the distribution of hydraulic properties within the extensive fractured zones identified by geophysics. A new analysis involving the 'dimension' of the flow test has been developed to analyse the results of the crosshole sinusoidal testing. The combined analysis of the geophysical and the hydraulic data set has shown that groundwater flow is concentrated within a few major features which have been identified by the geophysical methods.

  8. Laboratory investigations

    International Nuclear Information System (INIS)

    Handin, J.

    1980-01-01

    Our task is to design mined-repository systems that will adequately secure high-level nuclear waste for at least 10,000 yr and that will be mechanically stable for 50 to 100-yr periods of retrievability during which mistakes could be corrected and a valuable source of energy could be reclaimed, should national policy on the reprocessing of spent fuel ever change. The only credible path for the escape of radionuclides from the repository to the biosphere is through ground-water, and in hard rock, bulk permeability is largely governed by natural and artificial fracture systems. Catastrophic failure of an excavation in hard rock is likely to occur at the weakest links - the discontinuities in the rock mass that is perturbed first by mining and then by radiogenic heating. The laboratory can contribute precise measurements of the pertinent thermomechanical, hydrological and chemical properties and improve our understanding of the fundamental processes through careful experiments under well controlled conditions that simulate the prototype environment. Thus laboratory investigations are necessary, but they are not sufficient, for conventional sample sizes are small relative to natural defects like joints - i.e., the rock mass is not a continuum - and test durations are short compared to those that predictive modeling must take into account. Laboratory investigators can contribute substantially more useful data if they are provided facilities for testing large specimens(say one cubic meter) and for creep testing of all candidate host rocks. Even so, extrapolations of laboratory data to the field in neither space nor time are valid without the firm theoretical foundations yet to be built. Meanwhile in-situ measurements of structure-sensitive physical properties and access to direct observations of rock-mass character will be absolutely necessary

  9. Securing India's energy future

    2009-01-01

    India's development aspirations are challenged by energy security and climate change considerations. The integrated energy policy clearly deliberates the need to intensify all energy options with emphasis on maximizing indigenous coal production, harnessing hydropower, increasing adoption of renewables, intensifying hydrocarbon exploration and production and anchoring nuclear power development to meet the long-term requirements. The report also emphasizes the need to secure overseas hydrocarbon and coal assets. Subsequently the National Action Plan on climate change has underscored the need to wean away from fossil fuels, the ambitious National Solar Mission is a case in point. Ultimately securing India's energy future lies in clean coal, safe nuclear and innovative solar. Coal is the key energy option in the foreseeable future. Initiatives are needed to take lead role in clean coal technologies, in-situ coal gasification, tapping coal bed methane, coal to liquids and coal to gas technologies. There is need to intensify oil exploration by laying the road-map to open acreage to unlock the hydrocarbon potential. Pursue alternate routes based on shale, methane from marginal fields. Effectively to use oil diplomacy to secure and diversify sources of supply including trans-national pipelines and engage with friendly countries to augment strategic resources. Technologies to be accessed and developed with international co-operation and financial assistance. Public-Private Partnerships, in collaborative R and D projects need to be accelerated. Nuclear share of electricity generation capacity to be increased 6 to 7% of 63000 MW by 2031-32 and further to 25% (300000 MW) capacity by 2050 is to be realized by operationalizing the country's thorium programme. Nuclear renaissance has opened up opportunities for the Indian industry to meet not only India's requirements but also participate in the global nuclear commerce; India has the potential to emerge as a manufacturing hub

  10. Phenomenological Characteristics of Future Thinking in Alzheimer's Disease.

    2018-05-11

    This study investigates phenomenological reliving of future thinking in Alzheimer's disease (AD) patients and matched controls. All participants were asked to imagine in detail a future event, and afterward, were asked to rate phenomenological characteristics of their future thinking. As compared to controls, AD participants showed poor rating for reliving, travel in time, visual imagery, auditory imagery, language, and spatiotemporal specificity. However, no significant differences were observed between both groups in emotion and importance of future thinking. Results also showed lower rating for visual imagery relative to remaining phenomenological features in AD participants compared to controls; conversely, these participants showed higher ratings for emotion and importance of future thinking. AD seems to compromise some phenomenological characteristics of future thinking, especially, visual imagery; however, other phenomenological characteristics, such as emotion, seem to be relatively preserved in these populations. By highlighting the phenomenological experience of future thinking in AD, our paper opens a unique window into the conscious experience of the future in AD patients.

    The world population growth will impact largely on the energy and electric power demand in the future. Facing the decrease of the hydrocarbons reserves, the international community decided to work together to develop a new generation of nuclear systems. In this context, coordinated researches are realized first with a short dated objective on the development of innovations for PWR type reactors and second with a middle dated on the development of new systems in an international framework (essentially Generation IV). Theses research programs are presented below. The first part is devoted to the different generation of reactors (I to IV) and to the third generation; the second part deals with the international framework of the researches, the french strategy and the european dimension.

    In this challenging hydropower market, hydropower engineering services are in high demand. The number of new hydropower projects entering the pipeline may have slowed in recent years but that does not mean work is not being done. Independent developers, utilities and municipalities are carrying out a considerable amount of hydropower activity. Whatever the work involves - preliminary planning, licensing and relicensing, environmental mitigation, plant rehabilitation or new-plant startup - engineering firms are finding a brisk market for their services. The complexity of the regulatory framework makes hydropower facility and other water resource work more important then ever. Executives of three engineering firms - Acres International, Harza Engineering and Black and Veatch - active in these areas discuss their views on the future of the hydropower engineering market

    1977-06-01

    Canada could have 60,000 MW(e) of installed nuclear-electric generating capacity by the year 2000 and have exported the plan to generate a further 5,000 MW(e). While the CANDU reactor can readily be scaled up to larger unit sizes, its real potential lies in the even greater efficiency that can be obtained by using alternative fuel cycles. The thorium - uranium-233 fuel cycle, for instance, makes it possible to attain a conversion factor of unity, or a little better, on a feed of pure thorium in a substantially unmodified CANDU reactor. Further developments, such as spallation, offer means of converting fertile to fissile material to provide a fissile inventory for an expanding system. The coincidence of expected future shortages of other energy supplies with continuing good experience in the nuclear field should assist in creating a climate that will permit accelerated nuclear power development.

    Full Text Available Entrepreneurs are the gale of creative destruction. They are the engines of the local economy and contribute to a country’s wealth to a great extent. Accordingly it is of utmost importance, to create – educate and motivate – young adults to become entrepreneurs and start their own enterprises. The article summarises the basic facts about the Hungarian entrepreneurs’ and small and medium sized companies’ significance, and introduces a research on personal entrepreneurial competencies. The aim of the research is to explore the entrepreneurial potential of students in tertiary education, since they are the entrepreneurs of the future. In the research 470 young adults’ (students of tertiary education responses are compared with those of successful entrepreneurs. According to the results successful Hungarian entrepreneurs produced better results on the personal entrepreneurial competencies test, scoring in most cases higher than the members of the student sample. In addition to this, patterns based on age, gender and work experience could be identified

  19. Future in psychopathology research.

    Heckers, Stephan

    2014-03-01

    Psychopathology research has focused either on the analysis of the mental state in the here and now or on the synthesis of mental status abnormalities with biological markers and outcome data. These two schools of psychopathology, the analytic and the synthetic, make contrasting assumptions, take different approaches, and pursue divergent goals. Analytic psychopathology favors the individual person and unique biography, whereas synthetic psychopathology abstracts from the single case and generalizes to the population level. The dimension of time, especially the prediction of future outcomes, is viewed differently by these two schools. Here I outline how Carpenter's proposal of strong inference and theory testing in psychopathology research can be used to test the value of analytic and synthetic psychopathology. The emerging field of personalized psychiatry can clarify the relevance of psychopathology for contemporary research in psychiatry.

    2007-03-15

    Antibody purification seems to be safely ensconced in a platform, now well-established by way of multiple commercialized antibody processes. However, natural evolution compels us to peer into the future. This is driven not only by a large, projected increase in the number of antibody therapies, but also by dramatic improvements in upstream productivity, and process economics. Although disruptive technologies have yet escaped downstream processes, evolution of the so-called platform is already evident in antibody processes in late-stage development. Here we perform a wide survey of technologies that are competing to be part of that platform, and provide our [inherently dangerous] assessment of those that have the most promise.

    The research field of ambient media starts to spread rapidly and first applications for consumer homes are on the way. Ambient media is the logical continuation of research around media. Media has been evolving from old media (e.g. print media), to integrated presentation in one form (multimedia - or new media), to generating a synthetic world (virtual reality), to the natural environment is the user-interface (ambient media), and will be evolving towards real/synthetic undistinguishable media (bio-media or bio-multimedia). After the IT bubble was bursting, multimedia was lacking a vision of potential future scenarios and applications. Within this research paper the potentials, applications, and market available solutions of mobile ambient multimedia are studied. The different features of ambient mobile multimedia are manifold and include wearable computers, adaptive software, context awareness, ubiquitous computers, middleware, and wireless networks. The paper especially focuses on algorithms and methods that can be utilized to realize modern mobile ambient systems.

    2003-01-01

    Isotope Separation On-Line (ISOL) was first developed in Copenhagen in the late 50s. The technique was taken to CERN in the 60s and the CERN facility was given the name ISOLDE. The method is based on energetic protons hitting a solid target. The reaction products produced through spallation, fission and fragmentation are heated out in the form of an electrically neutral gas. In the subsequent steps the gas is ionized, accelerated and magnetically separated to produce isotopically pure beams for experiments in nuclear physics, atomic physics, astrophysics, solid state physics and for medical applications. An overview will be given of the physics at ISOLDE as well as over the techniques used to produce the necessary isotopes. Furthermore, a part of the talk will be dedicated to the future plans at ISOLDE including the proposal to build a next generation radioactive beam facility at CERN. The talk ends with a guided visit to the ISOLDE facility. Prerequisite knowledge: None.

    With the introduction of the Dornier HM3 lithotripter, the successful history of extracorporeal shock wave lithotripsy (ESWL) for noninvasive treatment of urinary stones began about 25 years ago. The development of newer lithotripters has not been able to improve clinical efficacy because the shock wave parameters specifically responsible for stone disintegration or tissue trauma and pain induction have not yet been identified. Actual research in lithotripter technology deals with modification of the focal point. The evolution of endoscopic procedures, ureterorenoscopy, and percutaneous nephrolithotomy took longer but was more successful in terms of clinical efficacy. Nowadays, ESWL or an endoscopic procedure is offered as a reasonable option for most urinary stone cases. Therefore, economic aspects and the surgeon's expertise will become greater factors when a procedure is chosen. ESWL, with or without anaesthesia, will be an inherent part of future treatment modalities for urinary stones.

    Full Text Available The Netherlands has a tradition in public spatial planning and design. In the past 20 years, we have seen an increasing role for the market in this field, and more recently, growing attention for sustainability. Sustainability has become an economic factor. Not only at the building level, but also on the level of large-scale area development projects. More and more local governments have high ambitions for sustainable development. Increasingly, during project development, buildings are developed on a sustainable basis. Most of the time, the focus in this approach is on energy. However, sustainability also comprises social aspects. Energy measures have a direct relation to an economic factor such as investment costs, and payback time can be calculated. The economic aspects of social sustainability are more complex. Therefore, for all sustainability development projects, especially in large-scale projects planned over a longer period, it is necessary to make presumptions, which are less reliable as the planning period is extended. For future larger-scale developments, experience in the Netherlands points to two design approaches: ‘backcasting’, or using a growth model (or a combination of these two. The power of design is the ability to imagine possible scenarios for the future. The layer approach helps to integrate sustainability into public spatial planning. And more specifically, Urban Design Management (UDM supports an integrative and collaborative approach also on the operational level of a project in which public and market partners work together. This article outlines how design, based on these approaches, can contribute to sustainable development based on the ‘new playing field’, where spatial problems should be solved in networks. Dutch projects in Almere (Benoordenhout and Rijswijk are used to illustrate this approach.

    This project aims primarily to give a basis for the joint R and D program for the Swedish electric utility industry, in the form of pictures of the future up to 2020. The work was performed during four seminars in a group of managers and R and D planners. The four scenarios differ mainly in the assumptions of high or low economic growth and on market or political rule. Assumptions on essential uncertainties about the future have been combined in a consistent manner, e.g. on the structure of the utility industry, the role of nuclear power, the importance of the greenhouse gas issue, the influence of new technology developments and on changes of values in society. Certain other development appear in all scenarios, e.g. the impact of information technology throughout society, the internationalization of business in general and industrial production in particular, considerations for the environment and care for natural resources. The four scenarios are: 'Technology on the throne' (market rule/high growth); 'Intense competition' (market rule/low growth); 'Monopoly takes over' (political rule/high growth); and 'Green local society' (political rule/low growth). Some of the important factors pointed out by the study are: Increased customer mobility between regions and countries; The impact of information technology; Societal value changes; Sustainable development as an important driving force; Structure of the utility industry. Diversifying into new services. New players; Access to knowledge and competence; Ways for handling the greenhouse gas problem; Preparedness for nuclear power phase-out. 12 figs, 6 tabs

  14. Shared visions, future challenges: a case study of three Collaborative Forest Landscape Restoration Program locations

    Full Text Available The USDA Forest Service is encouraging the restoration of select forest ecosystems through its Collaborative Forest Landscape Restoration Program (CFLRP. Collaboration is often necessary to implement landscape-scale management projects such as these, and a substantial body of research has examined the benefits and limitations of using collaboration as a tool for improving relationships, trust, and other outcomes among stakeholder groups. However, limited research has investigated the use of collaboration to achieve large-scale ecological restoration goals. Restoration poses some unique conditions for a collaborative approach, including reaching agreement on which historic conditions to use as a reference point, the degree of departure from these reference conditions that warrants management intervention, and how to balance historic conditions with expected future conditions and current human uses of the landscape. Using a mental-models approach, semistructured interviews were conducted with a total of 25 participants at three CFLRP sites. Results indicate that collaboration contributed to improved relationships and trust among participants, even among stakeholder groups with a history of disagreement over management goals. In addition, a shared focus on improving ecosystem resilience helped groups to address controversial management topics such as forest thinning in some areas. However, there was also evidence that CFLRP partnerships in our study locations have primarily focused on areas of high agreement among their stakeholders to date, and have not yet addressed other contentious topics. Previous studies suggest that first conducting management in areas with high consensus among participating stakeholders can build relationships and advance long-term goals. Nonetheless, our results indicate that achieving compromise in less obviously departed systems will require more explicit value-based discussions among stakeholders.

    1999-09-01

    Cyclic growing and melting of great ice sheets in the Northern Hemisphere is typical for the Quaternary Period, and it is likely that this cycle will continue in the future. This report discusses the principal processes predicted to occur during the future glaciation which are likely to be of importance for a nuclear waste repository. It is a revised version of a synthesis of the results of two state-of-the art reports, working meetings and a seminar. Based on present knowledge, two alternative trends (A and B) can be presented for fluctuations in climate in Fennoscandia. According to forecast A the climate will gradually become colder, permitting the growth of glaciers in the mountainous areas of Norway and Sweden after 5000 years. After a minor warmer period, a greater ice advance will cover a large part of Finland around 20 000 years from now. After a new minor interstade, the ice will advance again, so that c. 60 000 years from now the Stockholm-Helsinki region will be covered by thick ice. The ice sheet will melt partially at 70 000 years AP, but then it will grow to its maximum around 100 000 years AP and cover the whole Baltic basin. Almost complete melting of the ice sheet will take place during the next interglaciation c. 120 coo years AP. According to forecast B the growth of the ice sheet will not begin for another 50 000 years, and Finland will be covered by ice about 60 000 years from now. After a minor melting, the ice sheet will enlarge and cover almost the whole Baltic basin 100 000 years from now. During the following ice minimum, at 120 000 years AP, the ice sheet will still cover northern Finland. At 150 000 years it will cover the whole Baltic basin, but then it will melt almost completely by 165 000 years from now, during the following interglaciation. In both forecasts the main changes caused by the ice sheet will be downwarping/uplift of the crust and changes in sea level. In addition, changes in the groundwater head and flux are foreseen

    Future energy perspectives: 1) The global energy consumption will continue to grow primarily in developing countries, their share of global energy consumption will grow from approx. 35% in 1990 to 60% in 2050. 2) Policy focus will be primarily on environmental concerns in the industrial countries and on energy for development and access to energy for the poor in developing countries. 3) With global climate concerns and the implementation of the Kyoto protocol, global environment issues will have increased prominence in energy sector priorities. 4) Fossil fuel resources are on a global level still abundant and prices are expected to be relatively low in the short to medium term. 5) Energy supply security has for geopolitical reasons become an increasing concern especially in the US and the EU. 6) Significant investments are required to ensure development of new clean energy technologies for introduction in the medium to long term. 7) Market reforms are being implemented in almost all regions of the world changing both the investment and policy regimes. 8) International studies (IPCC and WEC) have analysed several alternative energy scenarios Alternative policies and priorities can lead to a wide range of different energy futures. 9) WEC middle scenario B, from 1990 to 2050; predicts growth in GDP 3.5 times and primary energy consumption 2.2 times and CO{sub 2} 1.5 times. This scenario is expecting supply to be dominated by fossil fuel (80% in 1990 and still 65% in 2050), with high share of natural gas and nuclear with slow growth in renewable energy. 10) A more radical scenario (C1) is expecting renewable energy such as biomass, solar and wind to contribute 27% in 2050; declining oil and coal; increased use of natural gas and a minor contribution from nuclear. A development path like this require significant near-term investments in technology research and development. 11) The large increase in global energy demand in the next century will require large investments

    Chronic constipation (CC) is a common gastrointestinal (GI) motility disorder that significantly impairs the quality of life in affected subjects. As almost half of the patients suffering from CC are not satisfied with currently available medicines, there is a need to develop new molecules with better effectiveness and tolerability. The authors include all experimental and clinical trials (up to Phase II) about new investigational drugs for the treatment of CC. The article identifies nine new agents: mitemcinal, TD-8954, YKP10811, itopride, RM-131, KWA-0711, elobixibat, velusetrag, and naronapride. All nine agents have shown prokinetic effects in different stages of the development. The mechanisms of new developing drugs include: the activation of 5-hydroxytryptamine type-4 (5-HT4), ghrelin and motilin receptors, antagonizing dopamine type-2 (D2) receptors, inhibition of ileal bile acid reabsorption and acetylcholine esterase, as well as water absorption from the GI tract. At this current point in time, new generations of 5-HT4 receptor agonists (velusetrag, noranopride and YKP10811) are hoped to progress, further in the future, due to better efficiency and safety. However, it is not possible to make a concise conclusion at this current time due to a lack of evidence. Further clinical trials with a longer duration and a larger sample size are warranted.

    The Large Hadron Collider (LHC) at CERN presently provides proton-proton collisions at a centre-of-mass (c.m.) energy of 13 TeV. The LHC design was started more than 30 years ago, and its physics programme will extend through the second half of the 2030’s. The global Future Circular Collider (FCC) study is now preparing for a post-LHC project. The FCC study focuses on the design of a 100-TeV hadron collider (FCC-hh) in a new ∼100 km tunnel. It also includes the design of a high-luminosity electron-positron collider (FCC-ee) as a potential intermediate step, and a lepton-hadron collider option (FCC-he). The scope of the FCC study comprises accelerators, technology, infrastructure, detectors, physics, concepts for worldwide data services, international governance models, and implementation scenarios. Among the FCC core technologies figure 16-T dipole magnets, based on $Nb_3Sn$ superconductor, for the FCC-hh hadron collider, and a highly efficient superconducting radiofrequency system for the FCC-ee lepton c...

    The Detroit Energy Conference has highlighted the declining oil reserves, estimated worldwide at 95 billion tons vs. an annual rate of consumption of over 3 billion tons. The present problem is one of price; also, petroleum seems too valuable to be simply burned. New sources must come into action before 1985. The most abundant is coal, with 600 billion tons of easily recoverable reserves; then comes oil shale with a potential of 400 billion tons of oil. Exploitation at the rate of 55 go 140 million tons/yr is planned in the U.S. after 1985. More exotic and impossible to estimate quantitatively are such sources as wind, tides, and the thermal energy of the oceans--these are probably far in the future. The same is true of solar and geothermal energy in large amounts. The only other realistic energy source is nuclear energy: the European Economic Community looks forward to covering 60% of its energy needs from nuclear energy in the year 2000. Even today, from 400 mw upward, a nuclear generating plant is more economical than a fossil fueled one. Conservation will become the byword, and profound changes in society are to be expected.

    Innovation and progress in radiation oncology depend on discovery and insights realized through research in radiation biology. Radiobiology research has led to fundamental scientific insights, from the discovery of stem/progenitor cells to the definition of signal transduction pathways activated by ionizing radiation that are now recognized as integral to the DNA damage response (DDR). Radiobiological discoveries are guiding clinical trials that test radiation therapy combined with inhibitors of the DDR kinases DNA-dependent protein kinase (DNA-PK), ataxia telangiectasia mutated (ATM), ataxia telangiectasia related (ATR), and immune or cell cycle checkpoint inhibitors. To maintain scientific and clinical relevance, the field of radiation biology must overcome challenges in research workforce, training, and funding. The National Cancer Institute convened a workshop to discuss the role of radiobiology research and radiation biologists in the future scientific enterprise. Here, we review the discussions of current radiation oncology research approaches and areas of scientific focus considered important for rapid progress in radiation sciences and the continued contribution of radiobiology to radiation oncology and the broader biomedical research community.

    Plans for future hadron colliders are presented, and accelerator physics and engineering aspects common to these machines are discussed. The Tevatron is presented first, starting with a summary of the achievements in Run IB which finished in 1995, followed by performance predictions for Run II which will start in 1999, and the TeV33 project, aiming for a peak luminosity $L ~ 1 (nbs)^-1$. The next machine is the Large Hadron Collider LHC at CERN, planned to come into operation in 2005. The last set of machines are Very Large Hadron Colliders which might be constructed after the LHC. Three variants are presented: Two machines with a beam energy of 50 TeV, and dipole fields of 1.8 and 12.6 T in the arcs, and a machine with 100 TeV and 12 T. The discussion of accelerator physics aspects includes the beam-beam effect, bunch spacing and parasitic collisions, and the crossing angle. The discussion of the engineering aspects covers synchrotron radiation and stored energy in the beams, the power in the debris of the p...

    The interest of politicians, businessmen, technologists, scientists and the people at large is focused today on the problem of energy. Everybody will agree on the fact that energy is necessary for the future of mankind. But many tend to paraphrase this by saying that energy is necessary evil. No objection to the necessity: but an analysis of the motivations for regarding energy as evil reveals some Freudian undertones. This scepticism towards technology, as a solution to the rising environmental concerns, perceived as a Faustian deal, after centuries of a passionate technical endeavour deeply engraved in the conception of the world, is a curious phenomenon to say the least. All these problems and the associated concerns are serious: the inevitable growth of energy consumption under the sheer momentum of society and the very human expectations of the poor, may indeed add enough yeast to make them leaven beyond control. However, like in the case of famine, illness etc., also here science and technology should be trusted; indeed there are reasonable expectations that, combined, they will have the possibility of solving also this problem, in full accord with the economic, dynamic and technical constraints that a working system has to comply with

    The CERN ISOLDE facility has operated for over 30 years delivering beams of exotic ions to an ever-growing user community. The facility went through a major up-grade in the early 1990s with the move from the 600 MeV synchrocyclotron to the 1 GeV PS-Booster proton synchrotron. This was followed by a primary proton beam energy up grade to 1.4 GeV in 1999. Lately, an important step forward was taken with the start of the REX-ISOLDE experiment for charge breeding and post acceleration of exotic ions. CERN has recently decided on a consolidation project for the facility to assure that the required number of shifts can be delivered in the future. An overview will be given of the on-going consolidation and development programme and its implications on the physics programme, in particular the REX-ISOLDE post accelerator experiment. An important parameter for a better yield of very exotic elements is the primary proton beam intensity, beam energy and time structure. The possible short-term improvements of, in particul...

    In the beginning, nanosatellite projects were focused on educational aspects. In the meantime, the technology matured and now allows to test, demonstrate and validate new systems, operational procedures and services in space at low cost and within much shorter timescales than traditional space endeavors. The number of spacecraft developed and launched has been increasing exponentially in the last years. The constellation of BRITE nanosatellites is demonstrating impressively that demanding scientific requirements can be met with small, low-cost satellites. Industry and space agencies are now embracing small satellite technology. Particularly in the USA, companies have been established to provide commercial services based on CubeSats. The approach is in general different from traditional space projects with their strict product/quality assurance and documentation requirements. The paper gives an overview of nanosatellite missions in different areas of application. Based on lessons learnt from the BRITE mission and recent developments at TU Graz (in particular the implementation of the OPS-SAT nanosatellite for ESA), enhanced technical possibilities for a future astronomy mission after BRITE will be discussed. Powerful on-board computers will allow on-board data pre-processing. A state-of-the-art telemetry system with high data rates would facilitate interference-free operations and increase science data return.

    California’s coastal observations and global model projections indicate that California’s open coast and estuaries will experience increasing sea levels over the next century. Sea level rise has affected much of the coast of California, including the Southern California coast, the Central California open coast, and the San Francisco Bay and upper estuary. These trends, quantified from a small set of California tide gages, have ranged from 10–20 centimeters (cm) (3.9–7.9 inches) per century, quite similar to that estimated for global mean sea level. So far, there is little evidence that the rate of rise has accelerated, and the rate of rise at California tide gages has actually flattened since 1980, but projections suggest substantial sea level rise may occur over the next century. Climate change simulations project a substantial rate of global sea level rise over the next century due to thermal expansion as the oceans warm and runoff from melting land-based snow and ice accelerates. Sea level rise projected from the models increases with the amount of warming. Relative to sea levels in 2000, by the 2070–2099 period, sea level rise projections range from 11–54 cm (4.3–21 in) for simulations following the lower (B1) greenhouse gas (GHG) emissions scenario, from 14–61 cm (5.5–24 in) for the middle-upper (A2) emission scenario, and from 17–72 cm (6.7–28 in) for the highest (A1fi) scenario. In addition to relatively steady secular trends, sea levels along the California coast undergo shorter period variability above or below predicted tide levels and changes associated with long-term trends. These variations are caused by weather events and by seasonal to decadal climate fluctuations over the Pacific Ocean that in turn affect the Pacific coast. Highest coastal sea levels have occurred when winter storms and Pacific climate disturbances, such as El Niño, have coincided with high astronomical tides. This study considers a range of projected future

    Full Text Available It has been my good fortune to live and practice radiology during a long period of momentous change – to see the transformation of the discipline from a supportive service into a mainstream, essential branch of clinical medicine. I remember wearing red goggles to adapt my vision before performing fluoroscopy; observing the horrible, now thankfully obsolete, practice of ventriculography, which was considered advanced neuroradiology; and performing other, now rarely prescribed procedures, such as double-contrast barium enemas and intravenous pyelography. Witnessing the beginnings of interventional radiology, I suggested its name in an editorial. I also had the good fortune to see the introduction of computed tomography (CT and a technology first known as nuclear magnetic resonance imaging. Together with fellow members of a committee of the American College of Radiology and editors of prestigious radiological journals, I took part in changing the name of the latter modality to MRI, freeing it from threatening implications. Looking back on these experiences, one lesson stands out above all: Innovation and transformation never cease. Looking forward, it is clear that radiology, along with the rest of medicine, is now undergoing further momentous changes that will affect the future of all those already practicing as well as those yet to start their careers.

    The foreseeable energy future will be driven by economics of known technologies and the desire to reduce CO 2 emissions to the atmosphere. Renewable energy options are compared with each other and with the use of fossil fuels with carbon capture and sequestration (CCS). Economic analysis is used to determine the best of several alternatives. One can disagree on the detailed costs, including externalities such as climate change and air and water pollution. But the differences in capital and operating costs between known technologies are so significant that one can draw clear conclusions. Results show that renewable energy cannot compete with fossil fuels on a cost basis alone because energy is intrinsic to the molecule, except for hydroelectricity. However, fossil fuels are implicated in climate change. Using renewable energy exclusively, including transportation and electricity needs, could reduce the standard of living in the United States by 43% to 62%, which would correspond to the level in about 1970. If capture and sequester of CO 2 are implemented, the cost of using fossil fuels will increase, but they beat renewable energy handily as an economic way to produce clean energy.

    This conference presentation examined OPEC future capacity expansions including highlights from 2000-2004 from the supply perspective and actions by OPEC; OPEC spare capacity in 2005/2006; medium-term capacity expansion and investments; long-term scenarios, challenges and opportunities; and upstream policies in member countries. Highlights from the supply perspective included worst than expected non-OPEC supply response; non-OPEC supply affected by a number of accidents and strikes; geopolitical tensions; and higher than expected demand for OPEC crude. OPEC's actions included closer relationship with other producers and consumers; capacity expansions in 2004 and 2005/2006; and OPEC kept the market well supplied with crude in 2004. The presentation also provided data using graphical charts on OPEC net capacity additions until 2005/2006; OPEC production versus spare capacity from 2003 to 2005; OPEC production and capacity to 2010; and change in required OPEC production from 2005-2020. Medium term expansion to 2010 includes over 60 projects. Medium-term risks such as project execution, financing, costs, demand, reserves, depletion, integration of Iraq, and geopolitical tensions were also discussed. The presentation concluded that in the long term, large uncertainties remain; the peak of world supply is not imminent; and continued and enhanced cooperation is essential to market stability. tabs., figs

  12. The future of memory

    Marinella, M.

    In the not too distant future, the traditional memory and storage hierarchy of may be replaced by a single Storage Class Memory (SCM) device integrated on or near the logic processor. Traditional magnetic hard drives, NAND flash, DRAM, and higher level caches (L2 and up) will be replaced with a single high performance memory device. The Storage Class Memory paradigm will require high speed (read/write), excellent endurance (> 1012), nonvolatility (retention > 10 years), and low switching energies (memory (PCM). All of these devices show potential well beyond that of current flash technologies and research efforts are underway to improve the endurance, write speeds, and scalabilities to be on-par with DRAM. This progress has interesting implications for space electronics: each of these emerging device technologies show excellent resistance to the types of radiation typically found in space applications. Commercially developed, high density storage class memory-based systems may include a memory that is physically radiation hard, and suitable for space applications without major shielding efforts. This paper reviews the Storage Class Memory concept, emerging memory devices, and possible applicability to radiation hardened electronics for space.

    The interest of politicians, businessmen, technologists, scientists and the people at large is focused today on the problem of energy. Everybody will agree on the fact that energy is necessary for the future of mankind. But many tend to paraphrase this by saying that energy is necessary evil.

  15. The future of antibiotics

    2014-01-01

    Antibiotic resistance continues to spread even as society is experiencing a market failure of new antibiotic research and development (R&D). Scientific, economic, and regulatory barriers all contribute to the antibiotic market failure. Scientific solutions to rekindle R&D include finding new screening strategies to identify novel antibiotic scaffolds and transforming the way we think about treating infections, such that the goal is to disarm the pathogen without killing it or modulate the host response to the organism without targeting the organism for destruction. Future economic strategies are likely to focus on ‘push’ incentives offered by public-private partnerships as well as increasing pricing by focusing development on areas of high unmet need. Such strategies can also help protect new antibiotics from overuse after marketing. Regulatory reform is needed to re-establish feasible and meaningful traditional antibiotic pathways, to create novel limited-use pathways that focus on highly resistant infections, and to harmonize regulatory standards across nations. We need new antibiotics with which to treat our patients. But we also need to protect those new antibiotics from misuse when they become available. If we want to break the cycle of resistance and change the current landscape, disruptive approaches that challenge long-standing dogma will be needed. PMID:25043962

    The IKONOS satellite has been operational since January 2000 and was the first commercial satellite collecting imagery with 1 meter resolution. The current life expectancy of the satellite is 10 years. Since the launch, Space Imaging Inc. (the owner of the satellite) supplied IKONOS imagery to users in many vertical markets, such as: agriculture, defense, oil & gas and telecommunications. This oral presentation will give comprehensive information about IKONOS and the future: * Block II, the successor of IKONOS. Space Imaging expects to launch in 2004 a new high-resolution satellite, ensuring both continuity and (for some years) a tandem operation with IKONOS, greatly improving the availability of imagery. * Space Imaging affiliates. IKONOS imagery collected, processed and sold by regional affiliates. These regional affiliates are strategically located around the world, like Japan Space Imaging (Tokyo), Space Imaging Middle East (Dubai) and Space Imaging Eurasia (Ankara, Turkey). * Technical briefing IKONOS. IKONOS (compared to other commercial high-resolution satellites) has superior collection capabilities. Due to, the higher orbit altitude, local reception of the imagery, bi-directional scanning and the high agility of the satellite, is the IKONOS satellite capable to collect the imagery relative quickly.

    The track was organized by the Department of Energy Technology, School of Engineering, at Aalto University. Energy future 2050 -track introduced participants to the global long-term challenges of achieving a sustainable energy supply. According to the Intergovernmental Panel on Climate Change (IPCC), effective climate change mitigation would require the global greenhouse gas emissions to be reduced by 50-85% from the present level by 2050. For industrialized countries, this would probably mean a practically carbon-neutral economy and energy supply, as developing countries need more possibilities for growth and probably enter stricter emission reduction commitments with some delay. In the beginning of the workshop, students were introduced to global energy scenarios and the challenge of climate change mitigation. Students worked in three groups with the following topics: How to gain public acceptance of Carbon (dioxide) Capture and Storage (CCS) ? Personal emissions trading as a tool to achieve deep emission cuts, How to get rid of fossil fuel subsidies? Nordic cases are peat use in Finland and Sweden. (orig.)

    The future evolution of global change and the atmosphere will depend largely on the paths of economic development and technological change, as well as on the physical, chemical, and biological processes of the Earth-atmosphere system. While we have no control over this system once gases enter the atmosphere, economic and technological change will be influenced by policy choices made at local, national, and international levels. This paper explores some of the paths the world might follow in the decades ahead and provides an indication of the relative climatic consequences under these alternatives. After a discussion of the economic and social factors that determine emissions, four scenarios of economic and technological development are presented. These scenarios cannot capture all the possibilities, of course; rather, they have been developed in order to explore the probable climatic effects under significantly different, but plausible, economic and technological conditions. The climatic implications of these scenarios are analyzed using an integrated framework. The chapter concludes with the results of this analysis and a comparison of these results with other studies

    The paper describes an investigation into the possible causes of lower-than-predicted tendon forces which were measured during past tendon surveillances for a concrete containment. The containment is post tensioned by vertical tendons which are anchored into a rock foundation. The tendons were originally stressed in 1969, and lift-off tests were performed on six occasions subsequent to this date over a period of 11 years. The tendon forces measured in these tests were generally lower than predicted, and by 1979 the prestress level in the containment was only marginally above the design requirement. The tendons were retensioned in 1980, and by this time an investigation into the possible causes was underway. Potential causes investigated include the rock anchors and surrounding rock, elastomeric pad creep, wire stresses, thermal effects, stressing equipment and lift-off procedures, and wire stress relaxation. The investigation activities included stress relaxation testing of wires pulled from actual tendons. The stress relaxation test program included wire specimens at several different temperature and initial stress levels and the effect of a varying temperature history on the stress relaxation property of the wires. For purpose of future force predictions of the retensioned tendons, the test program included tests to determine the effect on stress relaxation due to restressing the wires after they had relaxed for 1000 hours and 10,000 hours.

    We investigate the macro factors that can explain the monthly oil futures return for the NYMEX WTI futures contract for the time period 1993:11 to 2010:03. We build a new database of 187 real and nominal macro-economic variables from developed and emerging countries and resort to the large factor approximate model to extract 9 factors from this dataset. We then regress crude oil return on several combinations of these factors. Our best model explains around 38% of the variability of oil futures return. More interestingly, the factor which has the largest influence on crude oil price is related to real variables from emerging countries. This result confirms the latest finding in the literature that the recent evolution in oil price is attributable to change in supply and demand conditions and not to the large increase in trading activity from speculators.

    In prognosticating future perspectives, it is important to realize that the current number of small reactors throughout the world is not overly large and will undoubtedly decrease or at best remain constant in future generations. To survive and remain productive, small reactor facilities must concentrate on work that is unique and that cannot be performed as well by other instruments. Wherever possible, these facilities should develop some form of collaboration with universities and medical center investigators. Future development will continue and will flourish in neutron activation analysis and its applications for a diversity of fields. Fundamental research such as hot atom chemistry will continue to use neutrons from small research reactors. Finally, training of power reactor operators can be an important source of revenue for the small facility in addition to performing an important service to the nuclear power industry

    Individuals with pronounced self-transcendence values have been shown to put greater weight on the long-term consequences of their actions when making decisions. Using functional magnetic resonance imaging, we investigated the neural mechanisms underlying the evaluation of events occurring several decades in the future as well as the role of core values in these processes. Thirty-six participants viewed a series of events, consisting of potential consequences of climate change, which could occur in the near future (around 2030), and thus would be experienced by the participants themselves, or in the far future (around 2080). We observed increased activation in anterior VMPFC (BA11), a region involved in encoding the personal significance of future events, when participants were envisioning far future events, demonstrating for the first time that the role of the VMPFC in future projection extends to the time scale of decades. Importantly, this activation increase was observed only in participants with pronounced self-transcendence values measured by self-report questionnaire, as shown by a statistically significant interaction of temporal distance and value structure. These findings suggest that future projection mechanisms are modulated by self-transcendence values to allow for a more extensive simulation of far future events. Consistent with this, these participants reported similar concern ratings for near and far future events, whereas participants with pronounced self-enhancement values were more concerned about near future events. Our findings provide a neural substrate for the tendency of individuals with pronounced self-transcendence values to consider the long-term consequences of their actions.

    The CERN ISOLDE facility has operated for over 30 years delivering beams of exotic ions to an ever-growing user community. The facility went through a major up-grade in the early 1990s with the move from the 600 MeV synchrocyclotron to the 1 GeV PS-Booster proton synchrotron. This was followed by a primary proton beam energy up grade to 1.4 GeV in 1999. Lately, an important step forward was taken with the start of the REX-ISOLDE experiment for charge breeding and post-acceleration of exotic ions. CERN has recently decided on a consolidation project for the facility to assure that the required number of shifts can be delivered in the future. An overview will be given of the on-going consolidation and development programme and its implications on the physics programme, in particular the REX-ISOLDE post-accelerator experiment. An important parameter for a better yield of very exotic elements is the primary proton beam intensity, beam energy and time structure. The possible short-term improvements of, in particular, beam intensity will be discussed in some detail. While the main effort at CERN today goes towards the completion of the LHC, some resources have been found for accelerator R and D. A possible project is a new high intensity proton source at CERN, the superconducting proton linac, which could open the door to the construction of a next generation radioactive beam facility. The possible primary beam characteristics and some design considerations and their implications for such a facility will be discussed. Some ideas for the facility itself, such as the use of antiprotons and muons as new probes, production of a neutrino beam from stored radioactive ions and a preliminary design for a low energy storage ring, will be presented

    The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) presently provides proton-proton collisions at a center-of-mass (c.m.) energy of 13 TeV. The LHC design was started more than 30 years ago, and its physics program will extend through the second half of the 2030's. The global Future Circular Collider (FCC) study is now preparing for a post-LHC project. The FCC study focuses on the design of a 100-TeV hadron collider (FCC-hh) in a new ˜100 km tunnel. It also includes the design of a high-luminosity electron-positron collider (FCCee) as a potential intermediate step, and a lepton-hadron collider option (FCC-he). The scope of the FCC study comprises accelerators, technology, infrastructure, detectors, physics, concepts for worldwide data services, international governance models, and implementation scenarios. Among the FCC core technologies figure 16-T dipole magnets, based on Nb3 S n superconductor, for the FCC-hh hadron collider, and a highly-efficient superconducting radiofrequency system for the FCC-ee lepton collider. Following the FCC concept, the Institute of High Energy Physics (IHEP) in Beijing has initiated a parallel design study for an e + e - Higgs factory in China (CEPC), which is to be succeeded by a high-energy hadron collider (SPPC). At present a tunnel circumference of 54 km and a hadron collider c.m. energy of about 70 TeV are being considered. After a brief look at the LHC, this article reports the motivation and the present status of the FCC study, some of the primary design challenges and R&D subjects, as well as the emerging global collaboration.

    Since the last general symposium on Plowshare in 1964, significant progress has been made 1) in improving our understanding of explosion phenomenology, 2) in developing suitable explosive designs, and 3) in applying the technology to specific applications in the industrial, public works and scientific areas. The papers to be presented at this symposium will discuss in depth the progress that has been made in each of these areas, and to some degree, what still remains to be accomplished, so I will not attempt to go into detail here. However, I would like to take a few minutes to summarize where the technology stands today, where we believe it is going, and most importantly, how we hope to get there. In the excavation area, both Cabriolet and Schooner extended cratering experience in hard rock to higher yields. We also conducted Project Buggy, the first nuclear row-charge experiment. Buggy involved the simultaneous detonation of five 1.1 kiloton nuclear explosives, spaced 150 feet apart at a depth of 135 feet. The explosion created a smooth channel about 865 feet long, 254 feet wide and 70 feet deep. Two very significant contributions from Buggy were information on spacing between the explosives and on lip height. Buggy demonstrated that explosives can probably be spaced somewhat farther apart than previously thought without significantly affecting the smoothness of the channel. This could result in considerable savings in future row-charge excavations. We were also particularly pleased that, as predicted, the height of the lips at the end of the ditch was less than half the height of the lips on the sides - some 14 feet versus 41 feet. This is extremely important for the connecting of ditches. The data obtained from Buggy, Schooner and other experiments have been used to extend and refine our predictive capability.

    As our dependence on foreign oil increases and concerns about global climate change rise, the need to develop sustainable energy technologies is becoming increasingly significant. Worldwide energy consumption is expected to double by the year 2050, as will carbon emissions along with it. This increase in emissions is a product of an ever-increasing demand for energy, and a corresponding rise in the combustion of carbon containing fossil fuels such as coal, petroleum, and natural gas. Undisputable scientific evidence indicates significant changes in the global climate have occurred in recent years. Impacts of climate change and the resulting atmospheric warming are extensive, and know no political or geographic boundaries. These far-reaching effects will be manifested as environmental, economic, socioeconomic, and geopolitical issues. Offsetting the projected increase in fossil energy use with renewable energy production will require large increases in renewable energy systems, as well as the ability to store and transport clean domestic fuels. Storage and transport of electricity generated from intermittent resources such as wind and solar is central to the widespread use of renewable energy technologies. Hydrogen created from water electrolysis is an option for energy storage and transport, and represents a pollution-free source of fuel when generated using renewable electricity. The conversion of chemical to electrical energy using fuel cells provides a high efficiency, carbon-free power source. Hydrogen serves to blur the line between stationary and mobile power applications, as it can be used as both a transportation fuel and for stationary electricity generation, with the possibility of a distributed generation energy infrastructure. Hydrogen and fuel cell technologies will be presented as possible pollution-free solutions to present and future energy concerns.

    Bouchard, J.

    1992-01-01

    Today, more than 420 large reactors with a gross output of close to 350 GWe supply 20 percent of world electricity needs, accounting for less than 5 percent of primary energy consumption. These figures are not expected to change in the near future, due to suspended reactor construction in many countries. Nevertheless, world energy needs continue to grow: the planet's population already exceeds five billion and is forecast to reach ten billion by the middle of the next century. Most less developed countries have a very low rate of energy consumption and, even though some savings can be made in industrialized countries, it will become increasingly difficult to satisfy needs using fossil fuels only. Furthermore, there has been no recent breakthrough in the energy landscape. The physical feasibility of the other great hope of nuclear energy, fusion, has yet to be proved; once this has been done, it will be necessary to solve technological problems and to assess economic viability. Although it is more ever necessary to pursue fusion programs, there is little likelihood of industrial applications being achieved in the coming decades. Coal and fission are the only ways to produce massive amounts of energy for the next century. Coal must overcome the pollution problems inherent in its use; fission nuclear power has to gain better public acceptance, which is obviously colored by safety and waste concerns. Most existing reactors were commissioned in the 1970s; reactor lifetime is a parameter that has not been clearly established. It will certainly be possible to refurbish some to extend their operation beyond the initial target of 30 or 40 years. But normal advances in technology and safety requirements will make the operation of the oldest reactors increasingly difficult. It becomes necessary to develop new generations of nuclear reactors, both to replace older ones and to revive plant construction in their countries that are not yet equipped or that have halted their

    Starr, C.

    1979-01-01

    After examining briefly the usual positions of nuclear critics and nuclear proponents, Dr. Starr says that the proponents (of whom he is one) have a broader case for nuclear power not thus far effectively advanced - a case based chiefly on a visible concern with social values and the future welfare of humanity. Such a broader case for nuclear power has always existed - a case based on motivations that initially spurred development of this energy resource over the past several decades, but one that has tended to be neglected in the public debate. A concern to avoid worldwide catastrophe is central to this broader case for nuclear power. The threat is perceived as resulting directly from the pending unavailability of petroleum and natural gas at a reasonable cost. This unavailability could lead to global tensions and political instabilities, economic crises, and, ultimately, to military conflicts based on need to obtain and control liquid-fuel resources. It is felt that past history and current events substantiate the threat inherent in the international struggle for raw materials. The broader - and more compelling - case for nuclear power lies in its potential for removing a major threat to the peace, stability, and welfare of the world that is inherent in the growing scarcity of petroleum and natural gas resources and in the limited geographical availability of coal. The catastrophe that could be avoided is at least as threatening as the one projected by those who oppose the use of nuclear power, and, Dr. Starr argues, more realistic in its potential for world-shattering impacts

    Australia has one of the most cost-effective energy conversion and delivery systems in the world. We are blessed with abundant, high-quality fossil fuels consisting mainly of coal, gas and (diminishing) oil resources. However, this past blessing is also a future curse as this fuel mix, coupled with limits to hydroelectric growth and no nuclear generation capacity, has endowed Australia with one of the highest greenhouse gas (GHG) emissions per unit of GDP in the developed world (currently 43 per cent above the International Energy Agency average). This prompted Claude Mandil, head of the IEA, to observe: 'Environmental sustainability represent Australia's greatest energy challenge, with high and growing carbon dioxide emissions.' The challenge for Australia is how to make the massive cuts in GHG emissions required to minimise our world trade risks (which will come at a cost, and put pressure on our energy cost-effectiveness) while maintaining an internationally competitive energy sector. This challenge is exacerbated by a healthy national growth rate which will be accompanied by at least a 50 per cent growth in energy demand by 2020, with a doubling by 2050. Electricity industry projections predict an investment in new generation capacity well in excess of $30 billion to keep up with demand over the next two decades. The stark reality is that if we con tinue to supply and use energy the way we do now, we may as well forget about stabilising our GHG emissions from the energy sector, let alone reducing them in the future. This urgent situation presents a huge opportunity for the introduction of new and improved low-emission energy conversion technologies and demand management systems that vastly reduce GHG emissions per unit of productivity - in fact, an opportunity to transform Australia's energy sector to levels of innovation, social acceptance and environmental performance that has no precedent in this country. We have little choice other than to make a start. Are

    The new Asia-Pacific Greenhouse Agreement offers Australia a great opportunity to take full advantage of both its brains and its energy resources. The energy debate is often, simplistically, characterised as coal versus nuclear, or non-renewables versus renewables. In reality we will need a mix of energy sources to power our economy, cleanly, into the future. The issues are cost, environmental protection, national security, skills and security of energy supply. If we wish our economy to continue growing at present rates, we will need 50 per cent more energy in 2030 than we use today - and it is not too soon to start planning how we will produce it. We have around 500 years' supply of coal resources at present rates of usage. Power generation from coal is capable of achieving zero, or near zero, carbon emissions using technologies such as oxy-fuel combustion or IGCC (integrated gasification combined cycle). In both, C0 2 can be captured and stored underground. The greenhouse debate has revived interest in nuclear power generation. The cost of generating electricity with nuclear is similar to clean coal. However, we would have to start a nuclear power industry from a very small base, buying costly generation plant and training or importing an entire, highly-skilled workforce, in competition with other countries. Waste disposal is an issue for both coal and nuclear. For coal, the main option is carbon capture and its storage in deep saline aquifers. This technology is well understood and widely used by the oil and gas industry but we have to determine the most suitable places and techniques, and we have to build the infrastructure. Nuclear waste storage is also well-understood. Which technology we choose depends on an evaluation of both short and long term risks for the community and environment. One thing that Australia must get right is the economics. The wrong decision will cost us jobs, if not entire industries and regions. While renewables like solar and wind are

To construct ITER, the legal and work side of ITER operation has been investigated by four countries. However, their economic conditions have been changed to be wrong. So that, construction of ITER can not begin after end of industrial design activities in 1998. Accordingly, they determined to continue the industrial design activities more three years in order to study low cost options and to test the superconductive model·coil. (S.Y.)

    Despite the intrinsic temporal nature of procrastination, little research has examined the link between this form of self-regulatory failure and the consideration of future consequences, and no study has addressed the link between procrastination and episodic future thinking. The aim of the present study was to explore these relationships. Participants were asked to project themselves into possible future events and to rate the amount of sensory-perceptual details and autonoetic consciousness associated with their representations. They were also asked to complete questionnaires that assessed procrastination, the consideration of future consequences, and negative affect. Results showed that both the consideration of future consequences and episodic future thinking were associated with procrastination, and in particular with procrastination-related decision making abilities and procrastination-related motivational dispositions, respectively.

    Despite extensive examination of episodic memory and future thinking development, little is known about the concurrent emergence of these capacities during early childhood. In Experiment 1, 3-year-olds participated in an episodic memory hiding task ("what, when, where" [WWW] components) with an episodic future thinking component. In Experiment 2, a group of 4-year-olds (including children from Experiment 1) participated in the same task (different objects and locations), providing the first longitudinal investigation of episodic memory and future thinking. Although children exhibited age-related improvements in recall, recognition, and binding of the WWW episodic memory components, there were no age-related changes in episodic future thinking. At both ages, WWW episodic memory performance was higher than future thinking performance, and episodic future thinking and WWW memory components were unrelated. These findings suggest that the WWW components of episodic memory are potentially less fragile than the future components when assessed in a cognitively demanding task. © 2015 Wiley Periodicals, Inc.

    Endometriosis is a chronic disease with the potential to cause devastating clinical manifestations such as infertility and chronic pelvic disease. Current treatment is limited to surgical intervention and pharmacologic therapy targeting estrogen and progesterone to suppress ectopic endometrial tissue proliferation. Undesired side effects and contraindications to the use of hormonal medications may reduce treatment options. As the pathogenesis of endometriosis continues to be investigated, new therapies will emerge. The identification of genes involved in the development of endometriosis may allow targeted therapy to prevent or cure disease. In addition, increasing knowledge of the inflammatory pathways that promote ectopic endometrial growth will permit the development of pharmacologic agents to manipulate these signaling pathways. Utilization of selective progesterone receptor modulators, aromatase inhibitors, and modern gonadotropin-releasing hormone antagonists provide more options to manage disease when traditional treatment fails. Individualized therapeutic strategies will soon be a reality as a greater understanding of endometriosis is obtained through the investigation of genomic studies, molecular pathways, and environmental influences.

Advancements in stent design have led to prolonged patency and improved efficacy. However, biliary stenting is still affected by occlusion, migration, anatomical difficulties, and the need for repeat procedures. Multiple novel plastic biliary stent designs have recently been introduced with the primary goals of reduced migration and improved ease of placement. Self-expandable bioabsorbable stents are currently being investigated in animal models. Although not US Food and Drug Administration approved for benign disease, fully covered self-expandable metal stents are increasingly being used in a variety of benign biliary conditions. In malignant disease, developments are being made to improve ease of placement and stent patency for both hilar and distal biliary strictures. The purpose of this review is to describe recent developments and future directions of biliary stenting.Keywords: plastic stents, self-expandable metal stents, drug eluting stents, bioabsorbable stents, malignant biliary strictures, benign biliary strictures

  2. Executive Summary - Future plans

    International Nuclear Information System (INIS)

    2005-01-01

    Our Institute has sufficient scientific potential to play a key role in the field of particle physics, nuclear physics and in several aspects of solid state and applied physics, at least in our part of Europe. We believe the Institute should continue its present mode of operation, where basic research, closely coordinated through our collaboration with leading laboratories all over the world, stimulates our interdisciplinary research and technology transfer to the industry. If our present scientific potential is matched by suitably modernized infrastructure, we should be able to acquire the critical mass necessary for further effective development. In order to maintain our present world-level research, we have to continue and further extend our participation in large international collaborations, in the construction of large detectors and to seek further financial support from EU and international organizations. For experimental particle physics, our priorities remain in collaborating with major European and world laboratories such as CERN, DESY, Gran Sasso, Fermilab, KEK, SLAC and with laboratories developing astrophysics experiments, such as the PIERRE AUGER experiment. Collaboration in the field of nuclear physics, physics of condensed matter, theoretical physics and interdisciplinary research should be continued with leading European laboratories offering access to large accelerator facilities (such as GANIL or GSI), to synchrotron radiation or to unique polarized neutron beams, such as those available at ILL Grenoble. An exiting new frontier in research for our research teams will be opened by the X-ray Free Electron Laser (XFEL) in DESY and the future International Linear Collider. We will be able to further invest towards upgrading our small-scale facilities, such as the infrastructure around the Van de Graaff accelerator, in order to perform single-ion beam experiments, or around the AIC-144 cyclotron, to treat ocular melanoma, in close collaboration with

    Synopsis Cancer vaccines were one of the earliest forms of immunotherapy to be investigated. Past attempts to vaccinate against cancer, including melanoma, have mixed results, revealing the complexity of what was thought to be a simple concept. However, several recent successes and the combination of improved knowledge of tumor immunology and the advent of new immunomodulators make vaccination a promising strategy for the future.

    Clinician–investigators, also called physician–scientists, offer critical knowledge and perspectives that benefit research on basic science mechanisms, improved diagnostic and therapeutic approaches, population and outcomes medicine, health policy, and health services, yet few clinically trained health professionals pursue a research career. Sustaining this workforce requires attention to the unique challenges faced by investigators who must achieve clinical and research competence during training and their careers. These challenges include the duration of required clinical training, limited or discontinuous research opportunities, high levels of educational debt, balancing the dual obligations and rewards of clinical care and research, competition for research funding, and the need for leadership development after training. Women and individuals from underrepresented racial and ethnic groups comprise a small percentage of this workforce. The authors summarize the recent literature on training for clinician–investigators, emphasizing approaches with encouraging outcomes that warrant broader implementation. Using this overview as background, they convened three workshops at the National Institutes of Health in 2016 to identify and refine key priorities for potential new pilot programs to recruit and retain the clinician–investigator workforce. From these workshops emerged three priorities for future pilot programs: (1) support for research in residency, (2) new research on-ramps for health professionals at multiple career stages, and (3) national networks to diversify and sustain clinician–investigator faculty. Implementation of any pilot program will require coordinated commitment from academic health centers, medical licensing/certification boards, professional societies, and clinician–investigators themselves, in addition to support from the National Institutes of Health.

    Mango, Edward

    2011-01-01

    We, as NASA, continue to Dare Mighty Things. Here we are in October. In my country, the United States of America, we celebrate the anniversary of Christopher Columbus's arrival in the Americas, which occurred on October 12, 1492. His story, although happening over 500 years ago, is still very valid today. It is a part of the American spirit; part of the international human spirit. Columbus is famous for discovering the new world we now call America, but he probably never envisioned what great discoveries would be revealed many generations later. But in order for Columbus to begin his great adventure, he needed a business plan. Ho would he go about obtaining the funds and support necessary to build, supply, and man the ships required for his travels? He had a lot of obstacles and distractions. He needed a strong, internal drive to achieve his plans and recruit a willing crew of explorers also ready to risk their all for the unknown journey ahead. As Columbus set sail, he said "By prevailing over all obstacles and distractions, one may unfailingly arrive at his chosen goal or destination." Columbus may not have known he was on a journey for all human exploration. Recently, Charlie Bolden, the NASA Administrator, said, "Human exploration is and has always been about making life better for humans on Earth." Today, NASA and the U.S. human spaceflight program hold many of the same attributes as did Columbus and his contemporaries - a willing, can-do spirit. We are on the threshold of exciting new times in space exploration. Like Columbus, we need a business plan to take us into the future. We need to design the best ships and utilize the best designers, with their past knowledge and experience, to build those ships. We need funding and support from governments to achieve these goals of space exploration into the unknown. NASA does have that business plan, and it is an ambitious plan for human spaceflight and exploration. Today, we have a magnificent spaceflight

  11. The Cushing OK Crude Oil Futures Price Pass - Through to New York Harbor Reformulated RBOB Regular Gasoline Futures Price

    Directory of Open Access Journals (Sweden)

    Chu V. Nguyen

    2017-04-01

    Full Text Available This study utilizes an Autoregressive Distributed Lag model to investigate the nature of crude oil futures price pass-through since 2006. The empirical results reveal a very high but incomplete short-run pass-through rate from the crude oil futures price to the gasoline futures price of 0.849298 with a corresponding negative long-run pass-through rate of -0.2440894. These empirical findings suggest that traders in the U.S. oil and gasoline futures markets overreact to fluctuations in the crude oil futures price as evidenced by subsequent corrections made over the sample period. The result of the bounds test for a long-term relationship between these two futures prices is inconclusive. The empirical findings further suggest that U.S. futures market traders considered futures prices of gasoline three weeks earlier in determining the current trading price while taking only one week to respond completely to the shock in the crude oil futures price.  The empirical findings of this investigation may address the core elements of the price dynamics of the crude oil and gasoline futures markets and advance inquiry into assessment tools that could manage a very complex market challenge, especially for policy makers in countries with transitional economies in Eastern Europe, Caucasus and Central Asia.

    Activity and discoveries in spin physics of strong interactions has grown dramatically in recent years. What will we find in the future? I believe the future will be about the direct experimental exploration of confinement. While it is impossible to predict the 'future spin' of the whole community, my personal vision indicates we will teach ourselves how to use new coordinates for the gauge sector. New coordinates will be more appropriate for the new questions being asked. Contrary to long-held beliefs, there does exist alternatives to QCD. Not only will the future be about discovering the micro-structure of hadrons, but also new fundamental questions of principle will be confronted.

  14. Limited field investigation report for the 100-HR-1 Operable Unit

    1994-08-01

    This limited field investigation (LFI) report summarizes the data collection and analysis activities conducted during the 100-HR-1 Source Operable Unit LFI and the associated qualitative risk assessment (QRA) (WHC 1993a), and makes recommendations on the continued candidacy of high-priority sites for interim remedial measures (IRM). The results and recommendations presented in this report are generally independent of future land use scenarios. A LFI Report is required, in accordance with the HPPS, when waste sites are to be considered for IRMs. The LFI is an integral part of the remedial investigation/feasibility study (RI/FS) or Resource Conservation and Recovery Act (RCRA) facility investigation/corrective measures study (RFI/CMS) and process and functions as a focused RI or RFI for selection of IRMs. The purpose of the report is to identify those sites that are recommended to remain as candidates for IRMs, provide a preliminary summary of site characterization studies, refine the conceptual model as needed, identify contaminant- and location-specific applicable or relevant and appropriate requirements (ARA), and provide a qualitative assessment of the risks associated with the sites. This assessment includes consideration of whether contaminant concentrations pose an unacceptable risk that warrants action through IRMs. The 100-HR-1 unit encompasses approximately 100 acres adjacent to the Columbia River shoreline. It contains waste units associated with the original plant facilities constructed to support the H Reactor. The area also contains evaporation basins which received liquid process wastes and nonroutine deposits of chemical wastes from the 300 Area, where fuel elements for the N Reactor were produced

  17. The future of philosophy.

    1999-12-29

    There is no sharp dividing line between science and philosophy, but philosophical problems tend to have three special features. First, they tend to concern large frameworks rather than specific questions within the framework. Second, they are questions for which there is no generally accepted method of solution. And third they tend to involve conceptual issues. For these reasons a philosophical problem such as the nature of life can become a scientific problem if it is put into a shape where it admits of scientific resolution. Philosophy in the 20th century was characterized by a concern with logic and language, which is markedly different from the concerns of earlier centuries of philosophy. However, it shared with the European philosophical tradition since the 17th century an excessive concern with issues in the theory of knowledge and with scepticism. As the century ends, we can see that scepticism no longer occupies centre stage, and this enables us to have a more constructive approach to philosophical problems than was possible for earlier generations. This situation is somewhat analogous to the shift from the sceptical concerns of Socrates and Plato to the constructive philosophical enterprise of Aristotle. With that in mind, we can discuss the prospects for the following six philosophical areas: (1) the traditional mind-body problem; (ii) the philosophy of mind and cognitive science; (iii) the philosophy of language; (iv) the philosophy of society; (v) ethics and practical reasons; (vi) the philosophy of science. The general theme of these investigations, I believe, is that the appraisal of the true significance of issues in the philosophy of knowledge enables us to have a more constructive account of various other philosophical problems than has typically been possible for the past three centuries.

    Science.gov (United States)

    Beutels, Philippe; Scuffham, Paul A; MacIntyre, C Raina

    2008-11-01

    Vaccines have features that require special consideration when assessing their cost-effectiveness. These features are related to herd immunity, quality-of-life losses in young children, parental care and work loss, time preference, uncertainty, eradication, macroeconomics, and tiered pricing. Advisory committees on public funding for vaccines, or for pharmaceuticals in general, should be knowledgable about these special features. We discuss key issues and difficulties in decision making for vaccines against rotavirus, human papillomavirus, varicella-zoster virus, influenza virus, and Streptococcus pneumoniae. We argue that guidelines for economic evaluation should be reconsidered generally to recommend (1) modelling options for the assessment of interventions against infectious diseases; (2) a wider perspective to account for impacts on third parties, if relevant; (3) a wider scope of costs than health-care system costs alone, if appropriate; and (4) alternative discounting techniques to explore social time preference over long periods.

  9. A universal freeze all strategy: why it is not warranted.

    2017-06-01

    There's some preclinical evidence of an adverse effect of multifollicular growth on endometrial function in assisted reproductive technology cycles. Universal elective frozen embryo transfer (eFET) in an unstimulated cycle is being promoted as a panacea, regardless of patient, and cycle characteristics. We review the clinical evidence on the effectiveness and safety of eFETs. Randomized controlled trials (RCTs) comparing fresh and eFET yield contradictory results in terms of live birth rates. RCTs mainly involve women with an excessive response to ovarian stimulation. Studies including women with a normal or low ovarian response are either patient/physician preference or retrospective studies, prone to bias. Yet, they yield contradictory results as well. Overall, eFET seems to have limited potential to improve effectiveness of assisted reproductive technology, which could be limited to hyper-responders. Other suggested advantages of eFET include better obstetric and perinatal outcome. However, recent studies show that frozen embryo transfers can be associated with serious complications including hypertensive disorders during pregnancy, placenta accreta, or increased perinatal mortality. The evidence behind advantages of eFET is of low quality. As such, switching to a universal eFET strategy does not seem justified. New RCTs including women from different strata of ovarian response are needed.

    2013-07-01

    Full Text Available With methyl bromide's phase-out, most growers have turned to alternative fumigants, particularly 1,3-dichloropropene (1,3-D and chloropicrin. These alternatives are tightly regulated because they are classified as toxic air contaminants and volatile organic compounds; the latter combine with other substances to produce ground-level ozone (smog. Two ambient air monitoring studies were conducted to evaluate the potential of totally impermeable film (TIF to reduce emissions from shank applications of chloropicrin and 1,3-D. In 2009, a study demonstrated that TIF reduced chloropicrin and 1,3-D peak emissions by 45% and 38%, respectively, but TIF did not reduce total emissions when it was cut after 6 days. In 2011, increasing the tarp period from 5 to 10 days decreased chloropicrin and 1,3-D peak emissions by 88% and 78%, and their total emissions by 64% and 43%, respectively. Concurrent dynamic flux chamber results corroborated the ambient air monitoring data. These studies provide regulatory agencies with mitigation measures that should allow continued fumigant use at efficacious application rates.

    2004-09-30

    Two studies of the effects of perfume additives, termed human pheromones by the authors, have conveyed the message that these substances can promote an increase in human sociosexual behaviour [Physiol. Behav. 75 (2003) R1; Arch. Sex. Behav. 27 (1998) R2]. The present paper presents an extended analysis of this data. It is shown that in neither study is there a statistically significant increase in any of the sociosexual behaviours for the experimental groups. In the control groups of both studies, there are, however, moderate but statistically significant decreases in the corresponding behaviour. Most notably, there is no support in data for the claim that the substances increase the attractiveness of the wearers of the substances to the other sex. It is concluded that more research using matched homogenous groups of participants is needed. Copyright 2004 Elsevier Inc.

    Heelys, the new craze gripping the nation, were first introduced to Ireland in 2005 having been available in the United States since 2000. Designed as "the only shoe with a removable wheel in the sole" and initially marketed among rollerbladers and skateboarders they have been adopted by children as contemporary footwear. From April to June 2006, all patients presenting to trauma orthopaedic services at our institutions with injuries sustained while wearing Heelys were included in this study. Thirty-nine patients are included in this study. The mean age was 9.1 years (range 7-13, median 9 years). Of the 39 patients referred to the orthopaedic service, 8 required admissions to hospital. One patient admitted following a head injury, required craniotomy and evacuation of an extradural haematoma. The significance of the injuries encountered demonstrates the potentially devastating results from the use of Heelys. The public perception of safety is incorrect and manufacturers rightly recommend strongly the use of safety gear.

    Review of the articles. The objective of this study was to review all articles related to spinal instability to determine a consensus statement for a contemporary, practical definition applicable to thoracolumbar injuries. Traumatic fractures of the thoracolumbar spine are common. These injuries can result in neurological deficits, disability, deformity, pain, and represent a great economic burden to society. The determination of spinal instability is an important task for spine surgeons, as treatment strategies rely heavily on this assessment. However, a clinically applicable definition of spinal stability remains elusive. A review of the Medline database between 1930 and 2014 was performed limited to papers in English. Spinal instability, thoracolumbar, and spinal stability were used as search terms. Case reports were excluded. We reviewed listed references from pertinent search results and located relevant manuscripts from these lists as well. The search produced a total of 694 published articles. Twenty-five articles were eligible after abstract screening and underwent full review. A definition for spinal instability was described in only 4 of them. Definitions were primarily based on biomechanical and classification studies. No definitive parameters were outlined to define stability. Thirty-six years after White and Panjabi's original definition of instability, and many classification schemes later, there remains no practical and meaningful definition for spinal instability in thoracolumbar trauma. Surgeon expertise and experience remains an important factor in stability determination. We propose that, at an initial assessment, a distinction should be made between immediate and delayed instability. This designation should better guide surgeons in decision making and patient counseling.

    For the past six years, Westinghouse has used a Road Map process to direct technology development in a way that integrates the efforts of our businesses to addresses the needs of our customers and respond to significant drivers in the evolving business environment. As the nuclear industry experiences a resurgence, it is ever more necessary that we increase our planning horizon to 10-15 years in the future so as to meet the expectations of our customers. In the Future Point process, driven by the methods of Design for Six Sigma (DFSS), Westinghouse considers multiple possible future scenarios to plan long term evolutionary and revolutionary development that can reliably create the major products and services of the future market. the products and services of the future stretch the imagination from what we provide today. However, the journey to these stretch targets prompts key development milestones that will help deliver ideas useful for nearer term products. (Author) 1 refs

    To examine the impact of memory accessibility on episodic future thinking. Single-case study of neurological patient HCM and an age-matched comparison group of neurologically Healthy Controls. We administered a full battery of tests assessing general intelligence, memory, and executive functioning. To assess autobiographical memory, the Autobiographical Memory Interview (Kopelman, Wilson, & Baddeley, 1990. The Autobiographical Memory Interview. Bury St. Edmunds, UK: Thames Valley Test Company) was administered. The Past Episodic and Future Episodic sections of Dalla Barba's Confabulation Battery (Dalla Barba, 1993, Cogn. Neuropsychol., 1, 1) and a specifically tailored Mental Time Travel Questionnaire were administered to assess future thinking in HCM and age-matched controls. HCM presented with a deficit in forming new memories (anterograde amnesia) and recalling events from before the onset of neurological impairment (retrograde amnesia). HCM's autobiographical memory impairments are characterized by a paucity of memories from Recent Life. In comparison with controls, two features of his future thoughts are apparent: Reduced episodic future thinking and outdated content of his episodic future thoughts. This article suggests neuropsychologists should look beyond popular conceptualizations of the past-future relation in amnesia via focussing on reduced future thinking. Investigating both the quantity and quality of future thoughts produced by amnesic patients may lead to developments in understanding the complex nature of future thinking disorders resulting from memory impairments. We highlight the clinical importance of examining the content of future thoughts in amnesic patients, rather than only its quantitative reduction. We propose an explanation of how quantitative and qualitative aspects of future thinking could be affected by amnesia. This could provide a useful approach to understand clinical cases of impaired prospection. Systematic group investigations

    A mobile app appears to be a feasible means of addressing barriers to access, uptake and adherence in talking therapies for psychosis, and may reduce costs and improve outcomes. Wellcome Trust funding has recently been obtained to investigate integrating wearable technology into the app, with the aim of increasing its sensitivity to user needs and further reducing processing demands. A Thinkthru digital platform is also being designed for use during therapy sessions and will be synchronised with the app. Further investigation of the platform and app’s potential to facilitate meaningful behaviour change is warranted, and a feasibility study and randomised controlled trial are planned.

  3. The Future of Reproductive Autonomy.

    2017-12-01

    In a project The Hastings Center is now running on the future of prenatal testing, we are encountering clear examples, both in established law and in the practices of individual providers, of failures to respect women's reproductive autonomy: when testing is not offered to certain demographics of women, for instance, or when the choices of women to terminate or continue pregnancies are prohibited or otherwise not supported. But this project also raises puzzles for reproductive autonomy. We have learned that some clinicians and patients do not discuss the fact that prenatal testing can lead to a decision about whether to terminate a pregnancy-they just don't talk about it. And while the decision whether to agree to prenatal screening and diagnostic testing is to be made with women's free and informed consent, many screening tests have been routinized in such a way that some women do not even recall agreeing to testing, while others feel that agreeing to testing is what their clinicians expect of them or that the testing is necessary to protect themselves and their families from the significant financial hardship of raising a child with a disability. In the face of these pressures, can one really say that women are freely choosing to undergo testing or are freely choosing to continue or terminate a pregnancy following receipt of test results? The reality of these pressures is requiring us to consider expanding the scope of our investigation beyond the clinical encounter to the broader context-to think harder about what reproductive autonomy means and how best to enhance it. © 2017 The Hastings Center.

    The elements of a methodology to be employed by the global community to investigate the consequences of global environmental change upon future generations and global ecosystems are outlined in this paper. The methodology is comprised of two major components: A possible future worlds model; and a formal, citizen-oriented process to judge whether the possible future worlds potentially inheritable by future generations meet obligational standards. A broad array of descriptors of future worlds can be encompassed within this framework, including survival of ecosystems and other species and satisfaction of human concerns. The methodology expresses fundamental psychological motivations and human myths journey, renewal, mother earth, and being-in-nature-and incorporates several viewpoints on obligations to future generations-maintaining options, fairness, humility, and the cause of humanity. The methodology overcomes several severe drawbacks of the economic-based methods most commonly used for global environmental policy analysis.

    2006-09-01

    To prospectively study the stability of anabolic androgenic steroid (AAS) use and predictors of AAS use, and to investigate whether AAS use alters the risk of later emotional and behavioral problems. Survey of a national sample of Norwegian high school students (age 15-19) in 1994 followed up in 1999 (N = 2924). Measures of frequent alcohol intoxication (50+ times per 12 months), cannabis use (12 months), hard drug use (12 months), being offered cannabis, eating problems, conduct problems, sexual debut before age 15, BMI, involvement in power sports, perceived physical appearance, and satisfaction with body parts were obtained. Life-time prevalence of AAS use were 1.9 and 0.8% in the follow-up period. Multivariate logistic regression revealed that future AAS use was predicted by young age, male gender, previous AAS use, involvement in power sports, and frequent alcohol intoxication. AAS use did not predict future emotional or behavioral problems other than reducing the risk of future frequent alcohol intoxication. Frequent alcohol intoxication and involvement in power sports appear to predict future AAS use. At the population level there was little stability in individual AAS use from adolescence to early adulthood. No detrimental effects of AAS use could be detected in this study, but low statistical power limits this conclusion.

  8. Assessment of the possible future climatic impact of carbon dioxide increases based on a coupled one-dimensional atmospheric-oceanic model

    International Nuclear Information System (INIS)

    Hunt, B.G.; Wells, N.C.

    1979-01-01

    A radiative-convective equilibrium model of the atmosphere has been coupled with a mixed layer model of the ocean to investigate the response of this one-dimensional system to increasing carbon dioxide amounts in the atmosphere. For global mean conditions a surface temperature rise of about 2 0 K was obtained for a doubling of the carbon dioxide amount, in reasonable agreement with the commonly accepted results of Manabe and Wetherald. This temperature rise was essentially invariant with season and indicates that including a shallow (300 m) ocean slab in this problem does not basically alter previous assessments. While the mixed layer depth of the ocean was only very slightly changed by the temperature increase, which extended throughout the depth of the mixed layer, the impact of this increase on the overall behavior of the ocean warrants further study. A calculation was also made of the temporal variation of the sea surface temperature for three possible carbon dioxide growth rates starting from an initial carbon dioxide content of 300 ppm. This indicated that the thermal inertia of the slab ocean provides a time lag of 8 years in the sea surface temperature response compared to a land situation. This is not considered to be of great significance as regards the likely future climatic impact of carbon dioxide increase

  9. Forecasting oil price movements with crack spread futures

    International Nuclear Information System (INIS)

    Murat, Atilim; Tokat, Ekin

    2009-01-01

    In oil markets, the crack spread refers to the crude-product price relationship. Refiners are major participants in oil markets and they are primarily exposed to the crack spread. In other words, refiner activity is substantially driven by the objective of protecting the crack spread. Moreover, oil consumers are active participants in the oil hedging market and they are frequently exposed to the crack spread. From another perspective, hedge funds are heavily using crack spread to speculate in oil markets. Based on the high volume of crack spread futures trading in oil markets, the question we want to raise is whether the crack spread futures can be a good predictor of oil price movements. We investigated first whether there is a causal relationship between the crack spread futures and the spot oil markets in a vector error correction framework. We found the causal impact of crack spread futures on spot oil market both in the long- and the short-run after April 2003 where we detected a structural break in the model. To examine the forecasting performance, we use the random walk model (RWM) as a benchmark, and we also evaluate the forecasting power of crack spread futures against the crude oil futures. The results showed that (a) both the crack spread futures and the crude oil futures outperformed the RWM; and (b) the crack spread futures are almost as good as the crude oil futures in predicting the movements in spot oil markets.

  10. Oil futures and spot markets

    In the last decade, the oil futures market has risen to prominence and has become a major factor in influencing oil market psychology and the crude oil market. On a normal day, over 92 thousand contracts, the equivalent of 92 million barrels per day, change hands on the New York Mercantile Exchange, NYMEX. This market has provided a vehicle for hedging against risk. At the same time, it has also created opportunities for speculation. Those who previously were unable to participate in oil market transactions can now become involved through the futures market. The large number of participants in the future market and the availability of information has made this market more efficient and transparent, relative to the crude oil market. While there has been considerable in-depth analysis of other future markets, relatively little theoretical attention has focused on that of oil. This paper looks at the following issues. First, what is the relationship between futures and spot oil prices? And secondly, are futures prices a good predictor of spot crude prices in the future? (author)

    The capacity to plan ahead and provide the means for future ends is an important part of human practical reasoning. When this capacity develops in ontogeny is the matter of an ongoing debate. In this study, 4- and 5-year-olds performed a future planning task in which they had to create the means (a picture of a particular object, e.g., a banana) that was necessary to address a future end (of completing a game in which such a picture was missing). Children of both ages drew more targets than children in a control condition in which there was no future end to be pursued. Along with prior findings, the results suggest a major progression in children's future thinking between 3 and 5 years. Our findings expand on prior knowledge by showing that young children cannot only identify the probate means to future ends but determine such ends and create the means to achieve them, thus offering compelling evidence for future planning.

    Bartsch, Valeria

    2005-01-01

    Several methods to quantify the ''significance'' of an expected signal at future experiments have been used or suggested in literature. In this note, comparisons are presented with a method based on the likelihood ratio of the ''background hypothesis'' and the ''signal-plus-background hypothesis''. A large number of Monte Carlo experiments are performed to investigate the properties of the various methods and to check whether the probability of a background fluctuation having produced the claimed significance of the discovery is properly described. In addition, the best possible separation between the two hypotheses should be provided, in other words, the discovery potential of a future experiment be maximal. Finally, a practical method to apply a likelihood-based definition of the significance is suggested in this note. Signal and background contributions are determined from a likelihoo d fit based on shapes only, and the probability density distributions of the significance thus determined are found to be o...

    Full Text Available Purpose – The purpose of this paper is to investigate the major political and economic changes in the world and the likely impact that these changes will bring to tourism and hospitality industries. Design/methodology/approach – The paper adopts a geopolitical perspective on the dynamics of tourist flows, stipulating that geopolitics has a major impact on the size, structure, and direction of these flows. Findings – The paper identifies six geopolitical drivers of tourist flows in the future, namely: the fall of the American Empire, the rise of the BRIC and the PINE countries, increased global political instability, increased importance of regional supranational organisations, greater control of the individuals on a global scale, and the greater importance and power of corporations than national governments. Originality/value – The paper critically evaluates the geopolitical drivers of tourist flows, their likely future development and the impact they have on tourism.

    One item on the agenda of future colliders is certain to be the Higgs boson. What is it trying to tell us? The primary objective of any future collider must surely be to identify physics beyond the Standard Model, and supersymmetry is one of the most studied options. it Is supersymmetry waiting for us and, if so, can LHC Run 2 find it? The big surprise from the initial 13-TeV LHC data has been the appearance of a possible signal for a new boson X with a mass ~750 GeV. What are the prospects for future colliders if the X(750) exists? One of the most intriguing possibilities in electroweak physics would be the discovery of non-perturbative phenomena. What are the prospects for observing sphalerons at the LHC or a future collider?
