    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.

  4. Forgiveness and Consideration of Future Consequences in Aggressive Driving

    2008-01-01

    Most research on aggressive driving has focused on identifying aspects of driver personality which will exacerbate it (e.g., sensation seeking, impulsiveness, driving anger, etc.). The present study was designed to examine two theoretically relevant but previously unexplored personality factors predicted to reduce the risk of aggressive driving: trait forgiveness and consideration of future consequences. The utility of these variables in predicting aggressive driving and driving anger expression was evaluated among 316 college student volunteers. Hierarchical multiple regressions permitted an analysis of the incremental validity of these constructs beyond respondent gender, age, miles driven per week, and driving anger. Both forgiveness and consideration of future consequences contributed to the prediction of aggressive driving and driving anger expression, independent of driving anger. Research on aggressive driving may be enhanced by greater attention to adaptive, potentially risk-reducing traits. Moreover, forgiveness and consideration of future consequences may have implications for accident prevention. PMID:18760093

  9. Three Papers on the Political Consequences of Oil Prices

    NASA Astrophysics Data System (ADS)

    Crespo Tenorio, Adriana

    Given the importance of oil in any country's energy needs, it should not be surprising that the increasing volatility of oil prices in the past decades is a challenge for most political systems. While the political and economic impact of natural resource wealth in general is strongly debated, the political consequences of these sudden shifts have gone understudied. This dissertation examines the relationship between politics and oil from a new perspective. First, I implement a Bayesian meta-regression model to assess the state of research on the natural resource curse, finding that the measurement of resources is one of the most important sources of the debate. In the second part of the dissertation, I turn to discussing the impact of fuel prices on politics. I argue that at the domestic level, rational leaders feel pressured to compensate for oil price shocks because they are held accountable for these shifts by their constituents. This hypothesis is tested using Bayesian multilevel models that allow state and time-varying information to be matched to individual survey responses for a sample of voters in nine American states between 2008 and 2009. This chapter shows that fuel prices are related to appraisals of the economy only during electoral periods. The results also provide evidence that the degree to which voters use fuel prices to evaluate the president's performance varies greatly across party lines. At the global level, I posit in the final chapter that cross-country cooperation in other issue areas is pursued to mitigate the economic impact of oil price volatility. By developing a Bayesian bivariate Poisson change-point model and implementing it using MCMC methods, I find that fuel price shifts are related to increased trade networks, especially for oil-exporting countries.

  10. Portuguese Validation of the Consideration of Future Consequences Scale.

    PubMed

    Echeverría, Alejandro Vásquez; Esteves, Cristina; Gomes, Catarina Vilares; Ortuño, Victor E C

    2015-03-11

    The Consideration of Future Consequences Scale (CFC-S) is a measure of the extent to which individuals reflect and are influenced by the immediate as well as by the distant outcomes of current behavior. It's composed by 12 items, grouped into two subscales (future and immediate). This study aims to explore the factor structure, psychometric properties and construct validity of the Portuguese version of the CFC-S in 5 samples, composed by 527 participants with ages between 13 and 71. A 2 factor structure has been found through Confirmatory Factor Analysis among several tested models. Item 5 has been eliminated in order to achieve better fit indices (χ2 df = 3.88, CFI = .90, GFI = .95, RMSEA = .07) and improve internal consistency. Both CFC subscales presented strong correlations with several psychological phenomena (Sensation Seeking, Self-Esteem, Temporal Extension and Time Perspective) and main effects among groups of age and criminal record (for CFC-I, p < .001, for CFC-F, p < .001). These results allow us to support CFC as an efficient psychological evaluation instrument and as an important metric for individual differences in the study of temporal orientation.

  12. A flexible future for paper-based electronics

    NASA Astrophysics Data System (ADS)

    Liang, Tongfen; Zou, Xiyue; Mazzeo, Aaron D.

    2016-05-01

    This paper will review the origins and state of the art in paper-based electronics, suggesting the stage is set for future promising applications. Current interest in paper-based electronics can trace its roots to recent developments in paper-based microfluidics. With a need to improve the reliability and sensitivity of paperbased microfluidics for certain tasks, there were natural efforts to begin embedding sensing electrodes into microfluidic devices. Recognizing the general benefits of paper as an advanced material (e.g., its environmental friendliness, bendable nature, and low cost), efforts in paper-based electronics also began to take a life of their own with demonstrations of transistors, batteries and devices for energy storage, energy harvesting, sensors to improve situational awareness, acoustics, and displays. The state-of-the-art paper-based electronic devices have benefited and will continue to profit from technologies for printing and transferring electronic functionality onto the surfaces of paper-based substrates. Nonetheless, the authors suggest that many future promising applications will go beyond using paper as a carrier/substrate for electronic components to explore tuning of the electrical, mechanical, and chemical properties of the paper itself. With these technical advances, paper-based electronics will move closer to economically viable killer applications.

  13. Future So Bright? Delay Discounting and Consideration of Future Consequences Predict Academic Performance Among College Drinkers.

    Acuff, Samuel F; Soltis, Kathryn E; Dennhardt, Ashley A; Borsari, Brian; Martens, Matthew P; Murphy, James G

    2017-09-14

    College student drinking is a major public health concern and can result in a range of negative consequences, from acute health risks to decreased academic performance and drop out. Harm reduction interventions have been developed to reduce problems associated with drinking but there is a need to identify specific risk/protective factors related to academic performance among college drinkers. Behavioral economics suggests that chronic alcohol misuse reflects a dysregulated behavioral process or reinforcer pathology-alcohol is overvalued and the value of prosocial rewards are sharply discounted due, in part, to their delay. This study examined delay discounting, consideration of future consequences (CFC) and protective behavioral strategies (PBS) as predictors of academic success (grade point average; GPA) and engagement (time devoted to academic activities) among 393 college drinkers (61% female). In multivariate models, PBS were associated with greater academic engagement, but were not with academic success. Lower discounting of delayed rewards and greater CFC were associated with both academic success and engagement among drinkers. Previous research suggests that future time orientation is malleable, and the current results provide support for efforts to enhance future time orientation as part of alcohol harm-reduction approaches.

  1. The origin of scientific neurology and its consequences for modern and future neuroscience.

    PubMed

    Steinberg, David A

    2014-01-01

    John Hughlings Jackson (1835-1911) created a science of brain function that, in scope and profundity, is among the great scientific discoveries of the 19th century. It is interesting that the magnitude of his achievement is not completely recognized even among his ardent admirers. Although thousands of practitioners around the world use the clinical applications of his science every day, the principles from which bedside neurology is derived have broader consequences-for modern and future science-that remain unrecognized and unexploited. This paper summarizes the scientific formalism that created modern neurology, demonstrates how its direct implications affect a current area of neuroscientific research, and indicates how Hughlings Jackson's ideas form a path toward a novel solution to an important open problem of the brain and mind.

  2. Past and future implications of near-misses and their emotional consequences.

    PubMed

    Zhang, Qiyuan; Covey, Judith

    2014-01-01

    The Reflection and Evaluation Model (REM) of comparative thinking predicts that temporal perspective could moderate people's emotional reactions to close counterfactuals following near-misses (Markman & McMullen, 2003). The experiments reported in this paper tested predictions derived from this theory by examining how people's emotional reactions to a near-miss at goal during a football match (Experiment 1) or a close score in a TV game show (Experiment 2) depended on the level of perceived future possibility. In support of the theory it was found that the presence of future possibility enhanced affective assimilation (e.g., if the near-miss occurred at the beginning of the game the players who had nearly scored were hopeful of future success) whereas the absence of future possibility enhanced affective contrast (e.g., if the near-miss occurred at the end of the game the players who had nearly scored were disappointed about missing an opportunity). Furthermore the experiments built upon our theoretical understanding by exploring the mechanisms which produce assimilation and contrast effects. In Experiment 1 we examined the incidence of present-oriented or future-oriented thinking, and in Experiment 2 we examined the mediating role of counterfactual thinking in the observed effect of proximity on emotions by testing whether stronger counterfactuals (measured using counterfactual probability estimates) produce bigger contrast and assimilation effects. While the results of these investigations generally support the REM, they also highlight the necessity to consider other psychological mechanisms (e.g., social comparison), in addition to counterfactual thinking, that might contribute to the emotional consequences of near-miss outcomes.

  3. Temporal Consequences, Message Framing, and Consideration of Future Consequences: Persuasion Effects on Adult Fruit Intake Intention and Resolve.

    PubMed

    de Bruijn, Gert-Jan; Budding, Jeen

    2016-08-01

    Message framing is a persuasive strategy that has seen mixed evidence for promoting fruit intake intentions, potentially because framed messages for fruit intake have not (a) explicitly compared short-term consequences versus long-term consequences, (b) considered individual-level differences in time perspective, and (c) used alternative measures of fruit intake intentions. In the present online study, the effects of persuasive messages created from temporal context (short term vs. long term) and message frame (gain framed vs. loss framed) were investigated on fruit intake intentions and resolve among a sample of Dutch adults who were categorized as either present oriented or future oriented. For intention and resolve, results showed a significant Type of Frame × Type of Temporal Context interaction, such that gain-framed messages were more persuasive when combined with long-term consequences and loss-framed messages were more persuasive when combined with short-term consequences. The effect sizes for these differences were similar for resolve and intention, but only differences for intentions were significant. No other effects were found. These results demonstrate that message framing theory may usefully consider the inclusion of temporal context of outcomes and alternative motivation measures to maximize their persuasive effects.

    2006-06-01

    There are research requirements for trainees to be eligible to present for their final examinations (Fellowship of Royal Australasian College of Surgeons, FRACS). One option is the presentation of a paper or poster at a meeting of which abstracts are subject to review and selection. This includes presentation at the annual Registrars' Papers Day (RPD) in New South Wales. There has been some debate surrounding whether research requirements are fulfilled by presentation at such meetings. Publication in a peer-reviewed journal should be the ultimate aim. A high publication rate will validate the quality of the meeting. All abstracts submitted to the RPD in 1998 and 1999 were analysed. A Medline search was performed in 2005 to identify publication of these presentations in a peer-reviewed journal. Variables of the study that were potentially predictive of subsequent publication were analysed. This included type of presentation, surgical specialty, clinical or laboratory-based study, study design (prospective or retrospective) and sample size. Chi-squared test with Yates' continuity correction was used to compare two independent proportions and significance was set at P < 0.05. The publication rates were: oral presentations 50% (17/34), poster presentations 39% (9/23) and rejected presentations 20% (2/10). The mean and median time to publication was 23.8 and 21.0 months. Prospective design was the only variable identified to have a statistically significant effect on the publication rate (P < 0.002). The most common publishing journal was the Australian and New Zealand Journal of Surgery (12 of 26). Overall consistency (author and study sample consistency) from presentation to publication was 32%. The overall 46% publication rate of this state-based trainees-organized meeting compares favourably with international meetings. The research requirement of the Royal Australasian College of Surgeons (RACS), which includes presentation at the RPD in New South Wales, produces

    At present, a radical shift in cancer treatment is occurring in terms of predictive, preventive, and personalized medicine (PPPM). Individual patients will participate in more aspects of their healthcare. During the development of PPPM, many rapid, specific, and sensitive new methods for earlier detection of cancer will result in more efficient management of the patient and hence a better quality of life. Coordination of the various activities among different healthcare professionals in primary, secondary, and tertiary care requires well-defined competencies, implementation of training and educational programs, sharing of data, and harmonized guidelines. In this position paper, the current knowledge to understand cancer predisposition and risk factors, the cellular biology of cancer, predictive markers and treatment outcome, the improvement in technologies in screening and diagnosis, and provision of better drug development solutions are discussed in the context of a better implementation of personalized medicine. Recognition of the major risk factors for cancer initiation is the key for preventive strategies (EPMA J. 4(1):6, 2013). Of interest, cancer predisposing syndromes in particular the monogenic subtypes that lead to cancer progression are well defined and one should focus on implementation strategies to identify individuals at risk to allow preventive measures and early screening/diagnosis. Implementation of such measures is disturbed by improper use of the data, with breach of data protection as one of the risks to be heavily controlled. Population screening requires in depth cost-benefit analysis to justify healthcare costs, and the parameters screened should provide information that allow an actionable and deliverable solution, for better healthcare provision.

    1997-12-01

    On the request of the German and French safety authorities (German French Directorate, DFD) the German (RSK) and French (GPR) reactor safety commissions worked out recommendations for a common safety approach for future pressurized water reactors. Regarding the design to cover severe accidents, they recommended that the radiological consequences of low pressure core melt accident would necessitate only very limited protective measures in area and time (no permanent relocation, no need for emergency evacuation outside the immediate vicinity of the plant, limited sheltering, no long term restriction in consumption of food). The French/German constructors and utilities consortium NPI presented a design of a future European pressurized water reactor (EPR). Based on the design features of this new reactor GRS and IPSN calculated, with their methodology, the radiological consequences of a representative severe accident sequence with core meltdown. The evaluation of the results showed that the concept can fullfill the recommendation of GPR/RSK. 1 ref., 4 tabs.

    Studies of future management and policy options based on different assumptions provide a mechanism to examine possible outcomes and especially their likely benefits and consequences. The San Pedro River in Arizona and Sonora, Mexico is an area that has undergone rapid changes in land use and cover, and subsequently is facing keen environmental crises related to water resources. It is the location of a number of studies that have dealt with change analysis, watershed condition, and most recently, alternative futures analysis. The previous work has dealt primarily with resources of habitat, visual quality, and groundwater related to urban development patterns and preferences. In the present study, previously defined future scenarios, in the form of land-use/land-cover grids, were examined relative to their impact on surface-water conditions (e.g., surface runoff and sediment yield). These hydrological outputs were estimated for the baseline year of 2000 and predicted twenty years in the future as a demonstration of how new geographic information system-based hydrologic modeling tools can be used to evaluate the spatial impacts of urban growth patterns on surface-water hydrology.

    Sea-level rise (SLR) due to global warming will result in the loss of many coastal areas. The direct or primary effects due to inundation and erosion from SLR are currently being assessed; however, the indirect or secondary ecological effects, such as changes caused by the displacement of human populations, have not been previously evaluated. We examined the potential ecological consequences of future SLR on >1,200 islands in the Southeast Asian and the Pacific region. Using three SLR scenarios (1, 3, and 6 m elevation, where 1 m approximates most predictions by the end of this century), we assessed the consequences of primary and secondary SLR effects from human displacement on habitat availability and distributions of selected mammal species. We estimate that between 3-32% of the coastal zone of these islands could be lost from primary effects, and consequently 8-52 million people would become SLR refugees. Assuming that inundated urban and intensive agricultural areas will be relocated with an equal area of habitat loss in the hinterland, we project that secondary SLR effects can lead to an equal or even higher percent range loss than primary effects for at least 10-18% of the sample mammals in a moderate range loss scenario and for 22-46% in a maximum range loss scenario. In addition, we found some species to be more vulnerable to secondary than primary effects. Finally, we found high spatial variation in vulnerability: species on islands in Oceania are more vulnerable to primary SLR effects, whereas species on islands in Indo-Malaysia, with potentially 7-48 million SLR refugees, are more vulnerable to secondary effects. Our findings show that primary and secondary SLR effects can have enormous consequences for human inhabitants and island biodiversity, and that both need to be incorporated into ecological risk assessment, conservation, and regional planning. © 2012 Blackwell Publishing Ltd.

  7. Retrocausal Information Flow: What are the Consequences of Knowing the Future?

    Dobyns, York H.

    2006-10-01

    This paper discusses experimental findings from the Princeton Engineering Anomalies Research project supporting the existence of retrocausal information flow. Possible alternative explanations to retrocausation are examined for each experiment. In each case it can be shown that retrocausal information flow is either a parsimonious explanation, or the only currently available explanation, for the observational data. Gedankenexperiments are then examined to demonstrate that regardless of observational effect size, empirical phenomena of the type seen in these experiments cannot produce time paradoxes. The theoretical discussion pursuant to the experimental data covers some of the basic problems in the physical representation of time. Human perception of time incorporates a dichotomy: the past is known but cannot be changed, the future is presumed to be indeterminate and hence controllable but unknowable in advance. Physical formalisms have difficulty in representing this dichotomy, arriving in the most extreme case at the completely deterministic Einsteinian block universe view of spacetime. Strict physical determinism, however, currently seems implausible due to apparently essential indeterminism at the quantum scale. Retrocausal phenomena attack the dichotomy on empirical rather than theoretical grounds, since if past events can be causally influenced by future events either the past is malleable or the future is knowable. This approach allows a resolution of the past/future dichotomy by additional approaches other than strict determinism: the past may be indeterminate, or both past and future can contain a mixture of deterministic and indeterminate events.

  8. Future consequences of the strengthening of the ENSO-ENSO precursors association

    A series of the previous studies documented that ENSO would change in such a way that extreme ENSO happen more frequently and its association with the various precursors, such as sea surface anomalies over the Western North Pacific (WNP), become more robust. In this presentation, the multi-model and multi-ensemble analysis is performed to identify what are the consequences of these changes. For example, the 2013-2014 California drought was linked to the early phase of the ENSO, i.e., ENSO precursors, through an anomalous high-amplitude ridge system over the North Pacific Ocean. Under the global warming with more frequent extreme ENSO and the tighter ENSO-ENSO precursors association, what is the future of the drought over California and the Western United States? The multi-model archived in the CMIP5 and the multi-ensemble of CESM1 provide a unique opportunity to have more confident projection.

  9. Self-handicapping, excuse making, and counterfactual thinking: consequences for self-esteem and future motivation.

    PubMed

    McCrea, Sean M

    2008-08-01

    Researchers interested in counterfactual thinking have often found that upward counterfactual thoughts lead to increased motivation to improve in the future, although at the cost of increased negative affect. The present studies suggest that because upward counterfactual thoughts indicate reasons for a poor performance, they can also serve as excuses. In this case, upward counterfactual thoughts should result in more positive self-esteem and reduced future motivation. Five studies demonstrated these effects in the context of self-handicapping. First, upward counterfactual thinking was increased in the presence of a self-handicap. Second, upward counterfactual thoughts indicating the presence of a self-handicap protected self-esteem following failure. Finally, upward counterfactual thoughts that protect self-esteem reduced preparation for a subsequent performance as well as performance itself. These findings suggest that the consequences of upward counterfactuals for affect and motivation are moderated by the goals of the individual as well as the content of the thoughts.

  10. Promotion orientation explains why future-oriented people exercise and eat healthy: evidence from the two-factor consideration of future consequences-14 scale.

    2012-10-01

    The authors extended research linking individual differences in consideration of future consequences (CFC) with health behaviors by (a) testing whether individual differences in regulatory focus would mediate that link and (b) highlighting the value of a revised, two-factor CFC-14 scale with subscales assessing concern with future consequences (CFC-Future) and concern with immediate consequences (CFC-Immediate) proper. Exploratory and confirmatory factor analyses of the revised CFC-14 scale supported the presence of two highly reliable factors (CFC-Future and CFC-Immediate; αs from .80 to .84). Moreover, structural equation modeling showed that those high in CFC-Future engage in exercise and healthy eating because they adopt a promotion orientation. Future use of the two-factor CFC-14 scale is encouraged to shed additional light on how concern with future and concern with immediate consequences (proper) differentially impact the way people resolve a host of intertemporal dilemmas (e.g., health, financial, and environmental behavior).

  11. Future consequences of decreasing marginal production efficiency in the high-yielding dairy cow.

    PubMed

    Moallem, U

    2016-04-01

    The objectives were to examine the gross and marginal production efficiencies in high-yielding dairy cows and the future consequences on dairy industry profitability. Data from 2 experiments were used in across-treatments analysis (n=82 mid-lactation multiparous Israeli-Holstein dairy cows). Milk yields, body weights (BW), and dry matter intakes (DMI) were recorded daily. In both experiments, cows were fed a diet containing 16.5 to 16.6% crude protein and net energy for lactation (NEL) at 1.61 Mcal/kg of dry matter (DM). The means of milk yield, BW, DMI, NEL intake, and energy required for maintenance were calculated individually over the whole study, and used to calculate gross and marginal efficiencies. Data were analyzed in 2 ways: (1) simple correlation between variables; and (2) cows were divided into 3 subgroups, designated low, moderate, and high DMI (LDMI, MDMI, and HDMI), according to actual DMI per day: ≤ 26 kg (n=27); >26 through 28.2 kg (n=28); and >28.2 kg (n=27). The phenotypic Pearson correlations among variables were analyzed, and the GLM procedure was used to test differences between subgroups. The relationships between milk and fat-corrected milk yields and the corresponding gross efficiencies were positive, whereas BW and gross production efficiency were negatively correlated. The marginal production efficiency from DM and energy consumed decreased with increasing DMI. The difference between BW gain as predicted by the National Research Council model (2001) and the present measurements increased with increasing DMI (r=0.68). The average calculated energy balances were 1.38, 2.28, and 4.20 Mcal/d (standard error of the mean=0.64) in the LDMI, MDMI, and HDMI groups, respectively. The marginal efficiency for milk yields from DMI or energy consumed was highest in LDMI, intermediate in MDMI, and lowest in HDMI. The predicted BW gains for the whole study period were 22.9, 37.9, and 75.8 kg for the LDMI, MDMI, and HDMI groups, respectively. The

  12. Expectant futures and an early diagnosis of Alzheimer's disease: Knowing and its consequences.

    Swallow, Julia

    2017-07-01

    Efforts to diagnose Alzheimer's disease (AD) at earlier stages as a means to managing the risks of an ageing population, dominate scientific research and healthcare policy in the UK. It is anticipated that early diagnosis will maximise treatment options and enable patients to 'prepare for their future' in terms of care. Drawing on qualitative data gathered across an out-patient memory service and in-patient hospital in the UK, the purpose of this paper is to examine the ways in which the hopeful promissory claims of early diagnosis as it maintains the dominant biomedical model for managing AD, are negotiated by healthcare practitioners. Developing the analytical standpoint of the sociology of expectations, this paper demonstrates that early diagnosis has the potential to 'close off' hopeful promissory visions of the future in two ways. Firstly, it (re)produces the fearful anticipations of AD built around expectations concerning the ageing future 'self', and secondly it produces uncertainty in terms of the availability of care as material resource. Whilst practitioners account for the uncertainties and anxieties it produces for patients and their families, they also convey a sense of ambivalence concerning early diagnosis. This article captures the internal conflicts and contradictions inherent to practitioners' perspectives regarding the repercussions of early diagnosis and concludes by arguing that it effaces the uncertainties and anxieties that it produces in practice as it restricts the co-existence of narratives for making sense of memory loss beyond 'loss of self', and fails to recognise care as a viable alternative for managing AD.

    This workshop began with sessions to consider where the industry is likely to be, or ideally where it should be, say, by the year 2020. The next sessions considered the `drivers` that motivate the industry to change. These drivers could be motivations towards the vision developed earlier, or they may be forces that tend to prevent the vision of the future form being realized. The final sessions focused on what techniques are being (or should be) developed in four major process areas of a typical manufacturing plant, consistent with the previously identified vision of a future pulp or paper mill.

  2. Early signs of range disjunction of submountainous plant species: an unexplored consequence of future and contemporary climate changes.

    Poleward and upward species range shifts are the most commonly anticipated and studied consequences of climate warming. However, these global responses to climate change obscure more complex distribution change patterns. We hypothesize that the spatial arrangement of mountain ranges and, consequently, climatic gradients in Europe, will result in range disjunctions. This hypothesis was investigated for submountainous forest plant species at two temporal and spatial scales: (i) under future climate change (between 1950-2000 and 2061-2080 periods) at the European scale and (ii) under contemporary climate change (between 1914-1987 and 1997-2013 periods) at the French scale. We selected 97 submountainous forest plant species occurring in France, among which distribution data across Europe are available for 25 species. By projecting future distribution changes for the 25 submountainous plant species across Europe, we demonstrated that range disjunction is a likely consequence of future climate change. To assess whether it is already taking place, we used a large forest vegetation-plot database covering the entire French territory over 100 years (1914-2013) and found an average decrease in frequency (-0.01 ± 0.004) in lowland areas for the 97 submountainous species - corresponding to a loss of 6% of their historical frequency - along with southward and upward range shifts, suggesting early signs of range disjunctions. Climate-induced range disjunctions should be considered more carefully since they could have dramatic consequences on population genetics and the ability of species to face future climate changes.

    Emissions of aerosols and gases from fires have been shown to adversely affect air quality across the world. Fire activity is strongly related to climate and anthropogenic activities. Current fire projections for the 21st century seem very uncertain, ranging from increasing to declining depending on the climate, land cover change and population growth scenarios used. Here we present an analysis of the changes in future wildfire activity and consequences on air quality, with focus on PM2.5 and surface O3 over regions vulnerable to fire. We use the global Community Earth System Model (CESM) with a process-based fire model to simulate emissions from agriculture, peatland, deforestation and landscape fires for present-day and throughout the current century. We consider two future Representative Concentration Pathways climate scenarios combined with population density changes predicted from Shared Socio-economic Pathways to project climate and demographic effects on fire activity and further consequences for future air quality.

    Whilst it is agreed that climate change will impact on the long-term interactions between crops and weeds, the results of this impact are far from clear. We suggest that a thorough understanding of weed dominance and weed interactions, depending on crop and weed ecosystems and crop sequences in the ecosystem, will be the key determining factor for successful weed management. Indeed, we claim that recent changes observed throughout the world within the weed spectrum in different cropping systems which were ostensibly related to climate change, warrant a deeper examination of weed vulnerabilities before a full understanding is reached. For example, the uncontrolled establishment of weeds in crops leads to a mixed population, in terms of C3 and C4 pathways, and this poses a considerable level of complexity for weed management. There is a need to include all possible combinations of crops and weeds while studying the impact of climate change on crop-weed competitive interactions, since, from a weed management perspective, C4 weeds would flourish in the increased temperature scenario and pose serious yield penalties. This is particularly alarming as a majority of the most competitive weeds are C4 plants. Although CO2 is considered as a main contributing factor for climate change, a few Australian studies have also predicted differing responses of weed species due to shifts in rainfall patterns. Reduced water availability, due to recurrent and unforeseen droughts, would alter the competitive balance between crops and some weed species, intensifying the crop-weed competition pressure. Although it is recognized that the weed pressure associated with climate change is a significant threat to crop production, either through increased temperatures, rainfall shift, and elevated CO2 levels, the current knowledge of this effect is very sparse. A few models that have attempted to predict these interactions are discussed in this paper, since these models could play an integral

    Meat has been important to human survival and personal enjoyment for thousands of years, and as societies become more affluent, the amount and quality of meat consumed increases. Ancient Egyptians are known to have consumed ground meat, whereas the Greeks and Romans enjoyed various types of sausages. Ground meat has been consumed throughout the world under various names and for several centuries. However, in recent years, microbial meat safety has become a major concern, and it appears that meat safety challenges will persist in future years. This paper provides a brief historical account of selected developments in microbiology, meat science, and safety, and associated industrial and regulatory highlights, and a brief overview of current and future food safety issues, concerns, and challenges.

  10. Biodiversity consequences of alternative future land use scenarios in Greater Yellowstone.

    2007-06-01

    Land use is rapidly expanding in the Greater Yellowstone Ecosystem, primarily from growth in the number of rural homes. There is a need to project possible future land use and assess impacts on nature reserves as a guide to future management. We assessed the potential biodiversity impacts of alternative future land use scenarios in the Greater Yellowstone Ecosystem. An existing regression-based simulation model was used to project three alternative scenarios of future rural home development. The spatial patterns of forecasted development were then compared to several biodiversity response variables that included cover types, species habitats, and biodiversity indices. We identified the four biodiversity responses most at risk of exurban development, designed growth management policies to protect these areas, and tested their effectiveness in two alternative future scenarios. We found that the measured biodiversity responses, including riparian habitat, elk winter range, migration corridors, and eight other land cover, habitat, and biodiversity indices, are likely to undergo substantial conversion (between 5% and 40%) to exurban development by 2020. Future habitat conversion to exurban development outside the region's nature reserves is likely to impact wildlife populations within the reserves. Existing growth management policies will provide minimal protection to biodiversity in this region. We identified specific growth management policies, including incentives to cluster future growth near towns, that can protect "at risk" habitat types without limiting overall growth in housing.

    2016-09-01

    This study examines how individual difference in consideration of future consequences (CFC) and temporal framing (i.e., present- vs. future-oriented message) interact to influence the persuasive outcomes of a health message promoting human papillomavirus (HPV) vaccination among young adults. Results of an experiment (N = 416) showed a significant interaction effect of CFC and temporal framing on persuasion. The nature of the interaction suggested that individuals with high CFC generally were more persuaded by the present-oriented messages, compared to the future-oriented messages. On the other hand, those with low CFC responded similarly to the present- and future-oriented messages. Implications of the findings for HPV vaccination messaging are discussed.

    The present study examined relationships between individual differences in the consideration of future consequences, sleep habits and sleep quality, and academic achievement in a sample of 231 undergraduates, 156 women and 75 men, whose ages ranged from 18 to 41 years (M = 19.0 yr., SD=2.82). Individuals were recruited from two introductory courses and two upper-division courses, one each in the fields of biology and psychology. An 8-page questionnaire was administered to assess variables relating to personality, sleep habits and quality, and grade point average (GPA). Each volunteer was given extra credit in their respective courses for participation. Higher scores on the Consideration of Future Consequences scale were associated with self-reported measures of more regular sleep schedules, greater satisfaction with sleep, a reduced likelihood of oversleeping, and higher grade point averages. Moreover, oversleeping was significantly correlated with both scale scores and GPA.

    The last century of food animal agriculture is a remarkable triumph of scientific research. Knowledge derived through research has resulted in the development and use of new technologies that have increased the efficiency of food production and created a huge animal production and food manufacturing industry capable of feeding the US population while also providing significant quantities of high-quality food for export to other countries. Although the US food supply is among the safest in the world, the US Center for Disease Prevention and Control estimates that 76 million people get sick, more than 300,000 are hospitalized, and 5,000 die each year from foodborne illness. Consequently, preventing foodborne illness and death remains a major public health concern. Challenges to providing a safe, abundant, and nutritious food supply are complex because all aspects of food production, from farm to fork, must be considered. Given the national and international demand and expectations for food safety as well as the formidable challenges of producing and maintaining a safe food supply, food safety research and educational programs have taken on a new urgency. Remarkable progress has been made during the last century. Wisdom from a century of animal agriculture research now includes the realization that on-farm pathogens are intricately associated with animal health and well-being, the production of high-quality food, and profitability. In this review, some of the developments that have occurred over the last few decades are summarized, including types, sources, and concentrations of disease-causing pathogens encountered in food-producing animal environments and their association with food safety; current and future methods to control or reduce foodborne pathogens on the farm; and present and future preharvest food safety research directions. Future scientific breakthroughs will no doubt have a profound impact on animal agriculture and the production of high-quality food

  17. Time orientation and eating behavior: Unhealthy eaters consider immediate consequences, while healthy eaters focus on future health.

    Time orientation could play an important role in eating behavior. The current study investigated whether eating behavior is associated with the Consideration of Future Consequences scale (CFC). Specifically, it was examined whether unhealthy eaters consider the future less and are more concerned with immediate gratification. A related measure of time orientation is delay discounting, a process by which a reinforcer becomes less valuable when considered later in time. Recent research argues that the relation between time orientation and health behaviors is measured best at a behavior-specific level. In the current study, we explored the relationships between CFC and discount rate - both general and food-specific - and their influence on healthy eating. Participants with ages 18 to 60 (N = 152; final sample N = 146) filled in an online questionnaire consisting of the CFC, a food-specific version of the CFC (CFC-food), the Monetary Choice Questionnaire (MCQ) and an adapted MCQ version with snack food as a reinforcer. Self-reported healthy eating was positively related to the future subscale (r = .48, p < .001) and negatively to the immediate subscale of the CFC-food (r = -.43, p < .001). The general CFC and discount rate (MCQ and MCQ-snack) were not related to healthy eating (all p > .05). In order to predict behavior, measurements of time orientation should thus be tailored to the behavior of interest. Based on current results, shifting one's concern from the immediate consequences of eating to a more future-oriented perspective may present an interesting target for future interventions aimed at promoting healthy eating and reducing overweight.

    Forage-animal production agriculture is implementing infrastructure changes and management strategies to adjust to increased energy-related costs of fuel, feed grains, fertilizers, and seeds. The primary objectives of this position paper are to assess future research and extension scientific needs in forage utilization, financial support for the discipline, and changing status and number of scientists. A survey questionnaire returned from 25 land-grant universities in the eastern half of the United States rated the top 4 research needs as 1) pasture systems and efficiency of production; 2) interfacing with energy concerns; 3) forage cultivar evaluations and persistence; and 4) environment impacts. Plant-animal future research needs at 11 USDA-ARS regional locations are targeted at sustainable management and improved livestock performance, ecophysiology and ecology of grasslands, environment impacts, and improved technologies for nutritive value assessments. Extension scientists from 17 southern and northeastern states listed the top 3 needs as forage persistence, soil fertility and nutrient management, and pasture systems and efficiency of production. Grant funds currently provide more than 40% of land-grant university research and extension efforts in forage utilization, and scientists estimate that this support base will increase to 55 to 60% of the funding total by 2013. Reduced allocation of state and federal funding has contributed to a reduction in the number of full-time equivalent (FTE) scientists engaged in forage utilization research and extension activities. The current 25 state FTE conducting research number about 2.8 per state. This includes 10 states with >3, 11 states with <2, and 3 states with <1 FTE. Increased interest in cellulosic energy, climate change, and environmental impact may offer new opportunities for these FTE to participate in integrated cross-discipline research Extension programming, and technology transfer methods will change to

    Ongoing agricultural expansion in Amazonia and the surrounding areas of Brazil is expected to continue over the next several decades as global food demand increases. The transition of natural forest and cerrado ecosystems to pastureland and agricultural crops is predicted to create warmer and drier atmospheric conditions than the native vegetation. Using a coupled ecosystem- regional atmospheric model (ED-BRAMS) we investigate the impacts of predicted future land use on the climate of South America. We find that the climate response in our model is consistent with expectations - with drier conditions resulting from deforestation, however the changes in precipitation are moderate. Local drying is driven primarily by decreases in evapotranspiration associated with the loss of leaf area, and coincident increases in runoff. Significant consistent changes are seen in convectively available potential energy and convective inhibition suggesting that the decrease in surface latent heat flux is indeed leading to a drier atmosphere, however these changes occur at mean state values that are already very favorable for convection leading to little change in precipitation. If large-scale circulation changes occur in the future to push the atmosphere over the Amazon towards a drier state as predicted by the CMIP3 and CMIP5 archives, we postulate that land use change could accelerate the movement across a convective threshold.

    The gut of the human neonate is colonized rapidly after birth from an early sparse and highly distinct microbiota to a more adult-like and convergent state, within 1 to 3 years. The progression of colonizing bacterial species is non-random. During the first months of life several shifts commonly occur in the species prevalent in our guts. Although the sequential progression of these species is remarkably consistent across individuals and geographies, there is inter-individual variation in the rate of progression. Our study and others suggest that the rate is influenced by environmental factors, and influences our future health. In this article, we review our recent contribution to cataloging the developing infant gut microbiota alongside other important recent studies. We suggest testable hypotheses that arise from this synthesis. PMID:26516657

  8. Adolescent vulnerability to cardiovascular consequences of chronic emotional stress: Review and perspectives for future research.

    PubMed

    Crestani, Carlos C

    2017-03-01

    Emotional stress has been recognized as a modifiable risk factor for cardiovascular diseases. Adolescence has been proposed as a developmental period of vulnerability to stress. This idea has been mainly supported by experimental research in animals demonstrating a higher impact of chronic emotional stress in adolescents compared with adults. Adolescent vulnerability is also based on evidence that stress during this developmental period affects development, so that enduring changes are found in adult animals that experienced stress during adolescence. The purpose of the present review is to discuss experimental research in rodent models that investigated the impact of long-term exposure to stressful events during adolescence on cardiovascular function. The development of cardiovascular function and autonomic activity in rodents is initially reviewed. Then, a discussion of an adolescent vulnerability to cardiovascular effects of chronic stress is presented. From the reviewed literature, perspective for future research is proposed to better elucidate adolescent vulnerability to cardiovascular complications evoked by chronic emotional stress.

  10. Future directions in the ontogeny of plant defence: understanding the evolutionary causes and consequences.

    2017-04-01

    Plant defence often varies by orders of magnitude as plants develop from the seedling to juvenile to mature and senescent stages. Ontogenetic trajectories can involve switches among defence traits, leading to complex shifting phenotypes across plant lifetimes. While considerable research has characterised ontogenetic trajectories for now hundreds of plant species, we still lack a clear understanding of the molecular, ecological and evolutionary factors driving these patterns. In this study, we identify several non-mutually exclusive factors that may have led to the evolution of ontogenetic trajectories in plant defence, including developmental constraints, resource allocation costs, multi-functionality of defence traits, and herbivore selection pressure. Evidence from recent physiological studies is highlighted to shed light on the underlying molecular mechanisms involved in the regulation and activation of these developmental changes. Overall, our goal is to promote new research avenues that would provide evidence for the factors that have promoted the evolution of this complex lifetime phenotype. Future research focusing on the questions and approaches identified here will advance the field and shed light on why defence traits shift so dramatically across plant ontogeny, a widespread but poorly understood ecological pattern.

  11. Consequences of future increased Arctic runoff on Arctic Ocean stratification, circulation, and sea ice cover

    The Arctic Ocean has important freshwater sources including river runoff, low evaporation, and exchange with the Pacific Ocean. In the future, we expect even larger freshwater input as the global hydrological cycle accelerates, increasing high-latitude precipitation, and river runoff. Previous modeling studies show some robust responses to high-latitude freshwater perturbations, including a strengthening of Arctic stratification and a weakening of the large-scale ocean circulation; some idealized modeling studies also document a stronger cyclonic circulation within the Arctic Ocean itself. With the broad range of scales and processes involved, the overall effect of increasing runoff requires an understanding of both the local processes and the broader linkages between the Arctic and surrounding oceans. Here we adopt a more comprehensive modeling approach by increasing river runoff to the Arctic Ocean in a coupled ice-ocean general circulation model, and show contrasting responses in the polar and subpolar regions. Within the Arctic, the stratification strengthens, the halocline and Atlantic Water layer warm, and the cyclonic circulation spins up, in agreement with previous work. In the subpolar North Atlantic, the model simulates a colder and fresher water column with weaker barotropic circulation. In contrast to the estuarine circulation theory, the volume exchange between the Arctic Ocean and the surrounding oceans does not increase with increasing runoff. While these results are robust in our model, we require experiments with other model systems and more complete observational syntheses to better constrain the sensitivity of the climate system to high-latitude freshwater perturbations.

  12. Consequences of simulating terrestrial N dynamics for projecting future terrestrial C storage

    NASA Astrophysics Data System (ADS)

    Zaehle, S.; Friend, A. D.; Friedlingstein, P.

    2009-04-01

    We present results of a new land surface model, O-CN, which includes a process-based coupling between the terrestrial cycling of energy, water, carbon, and nitrogen. The model represents the controls of the terrestrial nitrogen (N) cycling on carbon (C) pools and fluxes through photosynthesis, respiration, changes in allocation patterns, as well as soil organic matter decomposition, and explicitly accounts for N leaching and gaseous losses. O-CN has been shown to give realistic results in comparison to observations at a wide range of scales, including in situ flux measurements, productivity databases, and atmospheric CO2 concentration data. Notably, O-CN simulates realistic responses of net primary productivity, foliage area, and foliage N content to elevated atmospheric [CO2] as evidenced at free air carbon dioxide enrichment (FACE) sites (Duke, Oak Ridge). We re-examine earlier model-based assessments of the terrestrial C sequestration potential using a global transient O-CN simulation driven by increases in atmospheric [CO2], N deposition and climatic changes over the 21st century. We find that accounting for terrestrial N cycling about halves the potential to store C in response to increases in atmospheric CO2 concentrations; mainly due to a reduction of the net C uptake in temperate and boreal forests. Nitrogen deposition partially alleviates the effect of N limitation, but is by far not sufficient to compensate for the effect completely. These findings underline the importance of an accurate representation of nutrient limitations in future projections of the terrestrial net CO2 exchanges and therefore land-climate feedback studies.

    It is well documented that global warming is unequivocal. Dairy production systems are considered as important sources of greenhouse gas emissions; however, little is known about the sensitivity and vulnerability of these production systems themselves to climate warming. This review brings different aspects of dairy cow production in Central Europe into focus, with a holistic approach to emphasize potential future consequences and challenges arising from climate change. With the current understanding of the effects of climate change, it is expected that yield of forage per hectare will be influenced positively, whereas quality will mainly depend on water availability and soil characteristics. Thus, the botanical composition of future grassland should include species that are able to withstand the changing conditions (e.g. lucerne and bird's foot trefoil). Changes in nutrient concentration of forage plants, elevated heat loads and altered feeding patterns of animals may influence rumen physiology. Several promising nutritional strategies are available to lower potential negative impacts of climate change on dairy cow nutrition and performance. Adjustment of feeding and drinking regimes, diet composition and additive supplementation can contribute to the maintenance of adequate dairy cow nutrition and performance. Provision of adequate shade and cooling will reduce the direct effects of heat stress. As estimated genetic parameters are promising, heat stress tolerance as a functional trait may be included into breeding programmes. Indirect effects of global warming on the health and welfare of animals seem to be more complicated and thus are less predictable. As the epidemiology of certain gastrointestinal nematodes and liver fluke is favourably influenced by increased temperature and humidity, relations between climate change and disease dynamics should be followed closely. Under current conditions, climate change associated economic impacts are estimated to be

    2015-01-01

    This research examines the influence of temporal framing (long-term vs. short-term) and individual difference in consideration of future consequences (CFC) on the effectiveness of cigarette health warnings among smokers and at-risk nonsmokers in a college population. An online experiment (N = 395) revealed a three-way interaction among temporal framing, CFC, and smoking status. The results among at-risk nonsmokers supported the temporal fit hypothesis--those high in CFC responded more favorably to long-term framing, whereas those low in CFC responded more positively to short-term framing. The findings among smokers revealed a different pattern in which short-term framing was more effective among high-CFC smokers, whereas among low-CFC smokers the framing effect was not distinct. Theoretical and practical implications of the findings are discussed.

  20. Colloquium paper: species invasions and extinction: the future of native biodiversity on islands.

    PubMed

    Sax, Dov F; Gaines, Steven D

    2008-08-12

    Predation by exotic species has caused the extinction of many native animal species on islands, whereas competition from exotic plants has caused few native plant extinctions. Exotic plant addition to islands is highly nonrandom, with an almost perfect 1 to 1 match between the number of naturalized and native plant species on oceanic islands. Here, we evaluate several alternative implications of these findings. Does the consistency of increase in plant richness across islands imply that a saturation point in species richness has been reached? If not, should we expect total plant richness to continue to increase as new species are added? Finally, is the rarity of native plant extinctions to date a misleading measure of the impact of past invasions, one that hides an extinction debt that will be paid in the future? By analyzing historical records, we show that the number of naturalized plant species has increased linearly over time on many individual islands. Further, the mean ratio of naturalized to native plant species across islands has changed steadily for nearly two centuries. These patterns suggest that many more species will become naturalized on islands in the future. We also discuss how dynamics of invasion bear upon alternative saturation scenarios and the implications these scenarios have for the future retention or extinction of native plant species. Finally, we identify invasion-motivated research gaps (propagule pressure, time-lags to extinction, abundance shifts, and loss of area) that can aid in forecasting extinction and in developing a more comprehensive theory of species extinctions.

  1. Shifting towards a model of mGluR5 dysregulation in schizophrenia: Consequences for future schizophrenia treatment.

    2017-03-15

    Metabotropic glutamate receptor subtype 5 (mGluR5), encoded by the GRM5 gene, represents a compelling novel drug target for the treatment of schizophrenia. mGluR5 is a postsynaptic G-protein coupled glutamate receptor strongly linked with several critical cellular processes that are reported to be disrupted in schizophrenia. Accordingly, mGluR5 positive allosteric modulators show encouraging therapeutic potential in preclinical schizophrenia models, particularly for the treatment of cognitive dysfunctions against which currently available therapeutics are largely ineffective. More work is required to support the progression of mGluR5-targeting drugs into the clinic for schizophrenia treatment, although some obstacles may be overcome by comprehensively understanding how mGluR5 itself is involved in the neurobiology of the disorder. Several processes that are necessary for the regulation of mGluR5 activity have been identified, but not examined, in the context of schizophrenia. These processes include protein-protein interactions, dimerisation, subcellular trafficking, the impact of genetic variability or mutations on protein function, as well as epigenetic, post-transcriptional and post-translational processes. It is essential to understand these aspects of mGluR5 to determine whether they are affected in schizophrenia pathology, and to assess the consequences of mGluR5 dysfunction for the future use of mGluR5-based drugs. Here, we summarise the known processes that regulate mGluR5 and those that have already been studied in schizophrenia, and discuss the consequences of this dysregulation for current mGluR5 pharmacological strategies.

  10. Advanced Low Conductivity Thermal Barrier Coatings: Performance and Future Directions (Invited paper)

    NASA Technical Reports Server (NTRS)

    Zhu, Dongming; Miller, Robert A.

    2008-01-01

    Thermal barrier coatings will be more aggressively designed to protect gas turbine engine hot-section components in order to meet future engine higher fuel efficiency and lower emission goals. In this presentation, thermal barrier coating development considerations and performance will be emphasized. Advanced thermal barrier coatings have been developed using a multi-component defect clustering approach, and shown to have improved thermal stability and lower conductivity. The coating systems have been demonstrated for high temperature combustor applications. For thermal barrier coatings designed for turbine airfoil applications, further improved erosion and impact resistance are crucial for engine performance and durability. Erosion resistant thermal barrier coatings are being developed, with a current emphasis on the toughness improvements using a combined rare earth- and transition metal-oxide doping approach. The performance of the toughened thermal barrier coatings has been evaluated in burner rig and laser heat-flux rig simulated engine erosion and thermal gradient environments. The results have shown that the coating composition optimizations can effectively improve the erosion and impact resistance of the coating systems, while maintaining low thermal conductivity and cyclic durability. The erosion, impact and high heat-flux damage mechanisms of the thermal barrier coatings will also be described.

  11. Future directions for career choice research in nursing: a discussion paper.

    PubMed

    Price, Sheri

    2009-02-01

    The last few decades have seen considerable changes in the characteristics of the healthcare workplace and workforce. There is a significant emphasis on recruitment and retention of healthcare providers internationally especially within the profession of Nursing, where there is a critical and growing shortage of nurses. Career choice is a critical component of recruitment and retention strategies and has significant organizational implications in regards to person-environment fit, career satisfaction and commitment. Many extant career choice theories fail to capture the challenges, complexities and uncertainties of the 21st century. Moreover, some early theories do not recognize the unique characteristics of upcoming generational cohorts and the multivariate influences on their career decisions. An extensive review and synthesis of the related literature provide the basis for a critical discussion on the adoption of new methodological approaches to exploring career choice in Nursing. The use of qualitative and mixed method approaches, a focus on generational differences and an exploration of adaptive and adjustment processes to career change provide a foundation for future career choice research and theoretical development which are reflective of the characteristics of the contemporary employee and the reality of modern healthcare organizations.

  12. ASAS centennial paper: net energy systems for beef cattle--concepts, application, and future models.

    PubMed

    Ferrell, C L; Oltjen, J W

    2008-10-01

    Development of nutritional energetics can be traced to the 1400s. Lavoisier established relationships among O(2) use, CO(2) production and heat production in the late 1700s, and the laws of thermodynamics and law of Hess were discovered during the 1840s. Those discoveries established the fundamental bases for nutritional energetics and enabled the fundamental entity ME = retained energy + heat energy to be established. Objectives became: 1) to establish relationships between gas exchange and heat energy, 2) to devise bases for evaluation of foods that could be related to energy expenditures, and 3) to establish causes of energy expenditures. From these endeavors, the basic concepts of energy partitioning by animals were developed, ultimately resulting in the development of feeding systems based on NE concepts. The California Net Energy System, developed for finishing beef cattle, was the first to be based on retained energy as determined by comparative slaughter and the first to use 2 NE values (NE(m) and NE(g)) to describe feed and animal requirements. The system has been broadened conceptually to encompass life cycle energy requirements of beef cattle and modified by the inclusion of numerous adjustments to address factors known to affect energy requirements and value of feed to meet those needs. The current NE system remains useful but is empirical and static in nature and thus fails to capture the dynamics of energy utilization by diverse animals as they respond to changing environmental conditions. Consequently, efforts were initiated to develop dynamic simulation models that captured the underlying biology and thus were sensitive to variable genetic and environmental conditions. Development of a series of models has been described to show examples of the conceptual evolution of dynamic, mechanistic models and their applications. Generally with each new system, advances in prediction accuracy came about by adding new terms to conceptually validated models

  13. Colloquium paper: Megafauna biomass tradeoff as a driver of Quaternary and future extinctions.

    PubMed

    Barnosky, Anthony D

    2008-08-12

    Earth's most recent major extinction episode, the Quaternary Megafauna Extinction, claimed two-thirds of mammal genera and one-half of species that weighed >44 kg between approximately 50,000 and 3,000 years ago. Estimates of megafauna biomass (including humans as a megafauna species) for before, during, and after the extinction episode suggest that growth of human biomass largely matched the loss of non-human megafauna biomass until approximately 12,000 years ago. Then, total megafauna biomass crashed, because many non-human megafauna species suddenly disappeared, whereas human biomass continued to rise. After the crash, the global ecosystem gradually recovered into a new state where megafauna biomass was concentrated around one species, humans, instead of being distributed across many species. Precrash biomass levels were finally reached just before the Industrial Revolution began, then skyrocketed above the precrash baseline as humans augmented the energy available to the global ecosystem by mining fossil fuels. Implications include (i) an increase in human biomass (with attendant hunting and other impacts) intersected with climate change to cause the Quaternary Megafauna Extinction and an ecological threshold event, after which humans became dominant in the global ecosystem; (ii) with continued growth of human biomass and today's unprecedented global warming, only extraordinary and stepped-up conservation efforts will prevent a new round of extinctions in most body-size and taxonomic spectra; and (iii) a near-future biomass crash that will unfavorably impact humans and their domesticates and other species is unavoidable unless alternative energy sources are developed to replace dwindling supplies of fossil fuels.

  14. Intuitive engineering, human factors, and the design of future interfaces (Invited Paper)

    NASA Astrophysics Data System (ADS)

    Sampson, James B.

    2005-05-01

    Human factors engineering (HFE) professionals complain that they are often called in after-the-fact to help correct human interface problems. They believe many design flaws can be avoided if design teams involve them early on. However, in the case of innovative technology, such post hoc human factors may not be avoidable unless the inventor is also a human factors engineer or the prospective user. In rare cases an inventor of a new technology has an intuitive understanding of human engineering principles and knows well the capabilities and limitations of operators. This paper outlines the importance of focusing on the user-system interface and encouraging engineers to develop their own intuitive sense of users through mental imagery. If design engineers start with a clear mental picture of a specific user and task rather than generalities of use, fewer interface problems are likely to be encountered later in development. Successful technology innovators often use a visual thinking approach in the development of new concepts. Examples are presented to illustrate the successful application of intuitive design. An approach is offered on how designers can improve their non-verbal thinking skills. The author shares the view that the mission of HFE should not be to make system developers dependent on the small community of HF experts but rather to help them learn the value of applying user-centered design techniques.

  15. Temporal framing and the decision to take part in type 2 diabetes screening: effects of individual differences in consideration of future consequences on persuasion.

    2006-07-01

    Reliable individual differences in the extent to which people consider the long- and short-term consequences of their own behaviors are hypothesized to influence the impact of a persuasive communication. In a field experiment, the time frame of occurrence of positive and negative consequences of taking part in a proposed Type 2 diabetes screening program was manipulated in a sample of 210 adults with a mean age of 53 years. Individual differences in consideration of future consequences (CFC; A. Strathman, F. Gleicher, D. S. Boninger, & C. S. Edwards, 1994) moderated (a) the generation of positive and negative thoughts and (b) the persuasive impact of the different communications. Low-CFC individuals were more persuaded when positive consequences were short term and negative consequences were long term. The opposite was true of high-CFC individuals. Path analyses show that net positive thoughts generated mediated the effect of the CFC x Time Frame manipulations on behavioral intentions.

  16. Review of the Structure of Bulk Power Markets Grid of the Future White Paper

    SciTech Connect

    Kirby, B.J.

    2000-05-02

    This paper is intended to provide an understanding of the needs of a restructured electricity market and some of the market methods and systems that have developed to address those needs. Chapter 2 discusses the historic market framework of vertically integrated utilities. Chapter 3 introduces the changes to the vertically integrated utility brought about by restructuring. It discusses generation and transmission planning, control and the regulatory process. It also summarizes reliability, security and adequacy. Chapter 4 discusses the basic structures of generation and transmission markets along with transmission-congestion contracts (TCCs) and transmission pricing principles. A discussion is given of the 12 ancillary services needed to reliably operate the power system. Chapter 4 also deals with the role of transmission in opening up markets to competition. In California increments (incs) and decrements (decs) are bid to overcome price differences in different zones caused by congestion. In PJM, any member can purchase Fixed Transmission Rights (FTRs) which allows the member to ''collect rent'' on congested lines and essentially obtain a hedge against congestion. There has been a worrisome slowdown in the growth of the transmission system in the United States since about the mid 70's. However, there are methods for providing incentives for construction of new transmission using tariffs. The California and PJM transmission planning processes are outlined. The Federal Energy Regulatory Commission (FERC) has recently issued a proposed rulemaking on Regional Transmission Organizations (RTOs) which stated that the traditional methods of grid management are showing signs of strain and may be inadequate to support efficient and reliable transmission operations. Chapter 5 provides examples of market implementations and a discussion of the price spikes seen in the Midwest in the summers of 1998 and 1999. An examination of six restructured market systems is performed in

    2014-01-01

    This research examines the influence of individual difference in consideration of future consequences on H1N1 vaccine uptake and H1N1-related health beliefs (i.e., perceived susceptibility to and severity of the H1N1 flu, perceived efficacy and safety of the H1N1 vaccine, and perceived self-efficacy in obtaining the H1N1 vaccine). A survey of 411 college students showed that consideration of future consequences had no direct effect on vaccine uptake, but higher consideration of future consequences was associated with greater perceived severity of the flu, higher perceived effectiveness of the vaccine, and greater perceived self-efficacy. Additional analysis suggested that consideration of future consequences had a significant indirect effect on vaccine uptake through perceived vaccine efficacy. Results of the study also revealed gender and racial differences in some of the H1N1-related health beliefs. Implications of the findings for vaccine risk communication are discussed.

    Lake ecosystems and the services that they provide to people are profoundly influenced by dissolved organic matter derived from terrestrial plant tissues. These terrestrial dissolved organic matter (tDOM) inputs to lakes have changed substantially in recent decades, and will likely continue to change. In this paper, we first briefly review the substantial literature describing tDOM effects on lakes and ongoing changes in tDOM inputs. We then identify and provide examples of four major challenges which limit predictions about the implications of tDOM change for lakes, as follows: First, it is currently difficult to forecast future tDOM inputs for particular lakes or lake regions. Second, tDOM influences ecosystems via complex, interacting, physical-chemical-biological effects and our holistic understanding of those effects is still rudimentary. Third, non-linearities and thresholds in relationships between tDOM inputs and ecosystem processes have not been well described. Fourth, much understanding of tDOM effects is built on comparative studies across space that may not capture likely responses through time. We conclude by identifying research approaches that may be important for overcoming those challenges in order to provide policy- and management-relevant predictions about the implications of changing tDOM inputs for lakes.

    With growing use of IT by healthcare professionals and patients, the opportunity for any unintended effects of technology to disrupt care health processes and outcomes is intensified. The objectives of this position paper by the IMIA Working Group (WG) on Technology Assessment and Quality Development are to highlight how our ongoing initiatives to enhance evaluation are also addressing the unintended consequences of health IT. Review of WG initiatives Results: We argue that an evidence-based approach underpinned by rigorous evaluation is fundamental to the safe and effective use of IT, and for detecting and addressing its unintended consequences in a timely manner. We provide an overview of our ongoing initiatives to strengthen study design, execution and reporting by using evaluation frameworks and guidelines which can enable better characterization and monitoring of unintended consequences, including the Good Evaluation Practice Guideline in Health Informatics (GEP-HI) and the Statement on Reporting of Evaluation Studies in Health Informatics (STARE-HI). Indicators to benchmark the adoption and impact of IT can similarly be used to monitor unintended effects on healthcare structures, processes and outcome. We have also developed EvalDB, a web-based database of evaluation studies to promulgate evidence about unintended effects and are developing the content for courses to improve training in health IT evaluation. Evaluation is an essential ingredient for the effective use of IT to improve healthcare quality and patient safety. WG resources and skills development initiatives can facilitate a proactive and evidence-based approach to detecting and addressing the unintended effects of health IT.

    SciTech Connect

    Haines, T.

    1995-09-01

    Cost-share assistance programs have been an effective policy mechanism for increasing productivity on nonindustrial private forest (NIPF) lands. In light of reduced harvests from Federal lands, timber productivity on these lands has become increasingly important to ensure sufficient timber supplies in the future. Productivity of other forest resources has also been enhanced through these programs. Four Federal programs, the Forestry Incentives Program, the Agricultural Conservation Program, the Stewardship Incentives program, and the Conservation Reserve Program, provided cost-share assistance for tree planting on 467,000 acres in 1993. During the course of this study, the provisions of the individual State programs, funding levels, accomplishments, and outlook for continuation or expansion, were examined. Federal programs were reviewed as well, with respect to their interaction with State-level programs. The results of the study are presented in this paper.

    Geoscientists now live in a world rich with digital data and methods, and their computational research cannot be fully captured in traditional publications. The Geoscience Paper of the Future (GPF) presents an approach to fully document, share, and cite all their research products including data, software, and computational provenance. This article proposes best practices for GPF authors to make data, software, and methods openly accessible, citable, and well documented. The publication of digital objects empowers scientists to manage their research products as valuable scientific assets in an open and transparent way that enables broader access by other scientists, students, decision makers, and the public. Improving documentation and dissemination of research will accelerate the pace of scientific discovery by improving the ability of others to build upon published work.

    2016-01-01

    Objective To conduct a systematic review of the literature examining risk and protective factors of alcohol related negative consequences (ARNCs) among adolescents. Methods We conducted a systematic search of original empirical articles published between January 1, 1990 and June 1, 2015. The qualitative synthesis was performed using the Theory of Triadic Influence as a framework. Results Fifty-two studies were reviewed. Intrapersonal (e.g., personality traits, drinking motives and expectancies, depression), interpersonal (e.g., parental and peer alcohol use, violence exposure) and attitudinal factors (e.g., media exposure to alcohol, religiosity) influence ARNCs. Emerging evidence of new trends contributing to ARNCs include ready mixed alcohol drinks and childhood trauma and abuse. Conclusions Risk factors from all domains of influence were observed. More research is needed on protective factors and how alcohol use interacts with preventive factors in predicting ARNCs. The conceptualization of negative consequences varies significantly between studies and may impact the external validity of previous research. PMID:26871952

    2014-05-01

    Changes to fire regimes in the future will be determined by a complex range of processes. Vegetation, weather and ignitions may be altered by climate change, elevated CO2 and human activity. In this study, we used an empirically based approach to project future changes in surface litter fuel within major vegetation formations (rainforest, wet sclerophyll forest, dry sclerophyll forest, grassy woodlands) the temperate and subtropical areas of south eastern Australia. Climatic controls of litterfall, decomposition and steady state fuel load within each vegetation formation were examined using metadata derived from field studies. Changes in steady state litter fuel load were then estimated for the current spatial domain of each vegetation formation (1 km grid), using the fuel/climate models, and a range of 2080 climate projections (5 GCMs) selected to encompass both warmer and drier and warmer and wetter future conditions for the region, under the A1b emissions scenario. Steady state surface fine fuel load was generally, negatively related to mean annual temperature but mean annual rainfall had divergent effects dependent on vegetation type. Under all 2080 climate projections, a mean decline in steady state surface litter was predicted in dry sclerophyll forest (-5 to -18%), the most extensive forest type in the region. Similarly a general decline was estimated for rainforest (-5 to -13%). For the other vegetation formations, predicted 2080 responses varied from a small mean increase to a more substantial decline: i.e. + 0.1 to - 24%, grassy woodlands; +3 to -18%, wet sclerophyll forest. The predominant, predicted decline in future surface fine fuel load has the potential to reduce future area burned due to the influence of fuel load on fire behaviour in these ecosystems. Early results from experiments and stand growth models dealing with Eucalyptus species indicate that possible declines in surface fine fuel load induced by a warmer climate may be partially off

    Previous work on temporal framing of health communications has focused upon detection behaviors that possess an inherent immediate risk of negative consequences. The present studies evaluate the role of temporal frame for a preventive behavior, using sunscreen. Two experimental field studies manipulated the temporal frame in which positive and negative consequences of using sunscreen were presented. Cognitive responses, intention, and behavior (experiment 2). Consistent with hypotheses, Experiment 1 showed that individual differences in consideration of future consequences (CFC; A. Strathman, F. Gleicher, D. S. Boninger, & C. S. Edwards, 1994) moderated (a) the processing of long- versus short-term consequences and (b) the persuasive impact of the different temporal frames on behavioral intentions. In Experiment 2, the balance of positive versus negative thoughts generated by reading the persuasive communications was shown to mediate the effects of the Temporal Frame x CFC interaction on a behavioral measure. Findings extend previous work by demonstrating the importance of individual differences in CFC to the processing of health communication about a preventive health behavior and to a behavioral outcome.

    Allergen exposure chambers (AECs) are clinical facilities allowing for controlled exposure of subjects to allergens in an enclosed environment. AECs have contributed towards characterizing the pathophysiology of respiratory allergic diseases and the pharmacological properties of new therapies. In addition, they are complementary to and offer some advantages over traditional multicentre field trials for evaluation of novel therapeutics. To date, AEC studies conducted have been monocentric and have followed protocols unique to each centre. Because there are technical differences among AECs, it may be necessary to define parameters to standardize the AECs so that studies may be extrapolated for driving basic immunological research and for marketing authorization purposes by regulatory authorities. For this task force initiative of the European Academy of Allergy and Clinical Immunology (EAACI), experts from academia and regulatory agencies met with chamber operators to list technical, clinical and regulatory unmet needs as well as the prerequisites for clinical validation. The latter covered the validation process, standardization of challenges and outcomes, intra- and interchamber variability and reproducibility, in addition to comparability with field trials and specifics of paediatric trials and regulatory issues. This EAACI Position Paper aims to harmonize current concepts in AECs and to project unmet needs with the intent to enhance progress towards use of these facilities in determining safety and efficacy of new therapeutics in the future. © 2017 John Wiley & Sons A/S.

    Geoscientists live in a world rich with digital data and methods, and their computational research cannot be fully captured in traditional publications. The Geoscience Paper of the Future (GPF) proposes best practices for GPF authors to make data, software, and methods openly accessible, citable, and well documented. Those best practices come from recommendations by both scholars and organizations concerning open science, reproducible publications, and digital scholarship. The publication of digital objects empowers scientists to manage their research products as valuable scientific assets in an open and transparent way that enables broader access by other scientists, students, decision makers, and the public. Improving documentation and dissemination of research will accelerate the pace of scientific discovery by improving the ability of others to build upon published work. This presentation summarizes these best practices, as well as the practical experiences of several GPF authors in different geosciences disciplines. It will also discuss existing challenges for authors and publishers to produce GPFs in practice, and the opportunities to develop new approaches and infrastructure to implement those best practices. The adoption of GPF recommendations requires awareness and social change in the scientific community, including clear communication of the benefits and best practices that may be new to geoscientists.

    Barriers and bridges to implement policies about sustainable development and sustainability commonly depend on the past development of social-ecological systems. Production of metals required integration of use of ore, streams for energy, and wood for bioenergy and construction, as well as of multiple societal actors. Focusing on the Swedish Bergslagen region as a case study we (1) describe the phases of natural resource use triggered by metallurgy, (2) the location and spatial extent of 22 definitions of Bergslagen divided into four zones as a proxy of cumulative pressure on landscapes, and (3) analyze the consequences for natural capital and society. We found clear gradients in industrial activity, stream alteration, and amount of natural forest from the core to the periphery of Bergslagen. Additionally, the legacy of top-down governance is linked to today's poorly diversified business sector and thus municipal vulnerability. Comparing the Bergslagen case study with other similar regions in Russia and Germany, we discuss the usefulness of multiple case studies.

    Due to temporal changes in the epidemiology of gonorrhea, a precise characterization of Neisseria gonorrhoeae is essential. In the present study genetic heterogeneity in the porB genes of N. gonorrhoeae was examined, and serovar determination was compared to porB gene sequencing. Among 108 N. gonorrhoeae isolates, phylogenetic analysis of the entire porB alleles (924 to 993 bp) identified 87 unique sequences. By analyzing only the four to six most heterogeneous porB gene regions (174 to 363 bp), 86 out of these 87 genetic variants were identified. Consequently, analysis of shorter highly variable regions of the porB gene generates high-level discriminatory ability as well as fast, objective, reproducible, and portable data for epidemiological characterization of N. gonorrhoeae. Regarding putative antigenic epitopes of PorB for Genetic Systems monoclonal antibodies (MAbs), some of the previous findings were confirmed, but new findings were also observed. For several of the MAbs, however, the precise amino acid residues of PorB critical for single-MAb reactivity were difficult to identify. In addition, repeated serovar determination of 108 N. gonorrhoeae isolates revealed discrepancies for 34 isolates, mostly due to nonreproducible reactivity with single MAbs. Thus, the prospects of a genetic typing system with congruent translation of the serovar determination seem to be limited. In conclusion, analysis of short highly variable regions of the porB gene could form the basis for a fast molecular epidemiological tool for the examination of emergence and transmission of N. gonorrhoeae strains within the community.

    2015-11-01

    To review the contemporary evidence reflecting male/female differences in alcohol use and its consequences along with the biological (sex-related) and psycho-socio-cultural (gender-related) factors associated with those differences. MEDLINE, PubMed, Web of Science, SCOPUS, PsycINFO, and CINAHL databases were searched for relevant publications, which were subsequently screened for the presence/absence of pre-specified criteria for high quality evidence. Compared to men, more women are lifetime abstainers, drink less, and are less likely to engage in problem drinking, develop alcohol-related disorders or alcohol withdrawal symptoms. However, women drinking excessively develop more medical problems. Biological (sex-related) factors, including differences in alcohol pharmacokinetics as well as its effect on brain function and the levels of sex hormones may contribute to some of those differences. In addition, differences in alcohol effects on behavior may also be driven by psycho-socio-cultural (gender-related) factors. This is evident by variation in the magnitude of differences in alcohol use between countries, decreasing difference in the rates of alcohol consumption in recent generations and other findings. Evidence indicates that both sex and gender-related factors are interacting with alcohol use in complex manner, which differentially impacts the risk for development of the behavioral or medical problems and alcohol use disorders in men and women. Discovery of the mechanisms underlying biological (sex-related) as well as psycho-socio-cultural (gender-related) differences in alcohol use and related disorders is needed for development of personalized recommendations for prevention and treatment of alcohol use disorders and related problems in men and women.

    We examined whether men with anabolic-steroid-induced hypogonadism (ASIH) seeking testosterone supplementation therapy (TST) regretted their decision to use anabolic-androgenic steroids (AAS) and what their reasons were for this regret. An anonymous, prospective survey was distributed to 382 men seeking follow-up treatment for hypogonadism. Prior AAS use was confirmed by self-report, and men were categorised based upon whether they regretted (R) or did not regret (NR) their use of AAS. The average patient age was 40 ± 0.9 years (n = 79) and 15.2% expressed regret over AAS use. No demographic differences were identified between those who regretted AAS use (n = 12) and those who did not (n = 67). Regret was not related to ASIH diagnosis or to AAS-related side effects like increased aggression, mood disorders, erectile dysfunction, acne, fluid retention or dyslipidemia. Those who regretted AAS use were significantly more likely to have not comprehended the negative impact on future fertility (P < 0.030). Actual fertility issues were comparable in men who regretted AAS use (16.7%) and those who did not (13%). A total of 15.2% of men regretted using AAS. A lack of awareness regarding the negative long-term effects on fertility was the primary factor related to regret of AAS use in men with ASIH. © 2014 Blackwell Verlag GmbH.

    Familiar to disaster risk reduction (DRR) scientists and professionals, the disaster cycle is an adaptive approach that involves planning, response and learning for the next event. It has proven effective in saving lives and helping communities around the world deal with natural and other hazards. But it has rarely been applied to natural resource and ecological science, despite the fact that many communities are dependent on these resources. This presentation will include lessons learned from applying science to tackle ecological consequences in several disasters in the US and globally, including the Colorado Floods, the SE Asia tsunami, the Montserrat volcanic eruption, and US SAFRR tsunami scenario. The presentation discusses the role that science and scientists can play at each phase of the disaster cycle. The consequences of not including disaster cycles in the management of natural systems leaves these resources and the huge investments made to protect highly vulnerable. The presentation discusses how The presentation discusses how science can help government and communities in planning and responding to these events. It concludes with a set of lessons learned and guidlines for moving forward.

    Substantial ecological changes occurred in the 1970s in the Northern Baltic during a temporary period of low salinity (S). This period was preceded by an episodic increase in the rainfall over the Baltic Sea watershed area. Several climate models, both global and regional, project an increase in the runoff of the Northern latitudes due to proceeding climate change. The aim of this study is to model, firstly, the effects on Baltic Sea salinity of increased runoff due to projected global change and, secondly, the effects of salinity change on the distribution of marine species. The results suggest a critical shift in the S range 5–7, which is a threshold for both freshwater and marine species distributions and diversity. We discuss several topics emphasizing future monitoring, modelling, and fisheries research. Environmental monitoring and modelling are investigated because the developing alternative ecosystems do not necessarily show the same relations to environment quality factors as the retiring ones. An important corollary is that the observed and modelled S changes considered together with species’ ranges indicate what may appear under a future climate. Consequences could include a shift in distribution areas of marine benthic foundation species and some 40–50 other species, affiliated to these. This change would extend over hundreds of kilometres, in the Baltic Sea and the adjacent North Sea areas. Potential cascading effects, in coastal ecology, fish ecology and fisheries would be extensive, and point out the necessity to develop further the “ecosystem approach in the environmental monitoring”.

  9. Past and future demographic dynamics of alpine species: limited genetic consequences despite dramatic range contraction in a plant from the Spanish Sierra Nevada.

    2013-08-01

    Anthropogenic global climate change is expected to cause severe range contractions among alpine plants. Alpine areas in the Mediterranean region are of special concern because of the high abundance of endemic species with narrow ranges. This study combined species distribution models, population structure analyses and Bayesian skyline plots to trace the past and future distribution and diversity of Linaria glacialis, an endangered narrow endemic species that inhabits summits of Sierra Nevada (Spain). The results showed that: (i) the habitat of this alpine-Mediterranean species in Sierra Nevada suffered little changes during glacial and interglacial stages of late Quaternary; (ii) climatic oscillations in the last millennium (Medieval Warm Period and Little Ice Age) moderately affected the demographic trends of L. glacialis; (iii) future warming conditions will cause severe range contractions; and (iv) genetic diversity will not diminish at the same pace as the distribution range. As a consequence of the low population structure of this species, genetic impoverishment in the alpine zones of Sierra Nevada should be limited during range contraction. We conclude that maintenance of large effective population sizes via high mutation rates and high levels of gene flow may promote the resilience of alpine plant species when confronted with global warming. © 2013 John Wiley & Sons Ltd.

This detailed section discusses the prospects for dark matter detection with future gamma-ray experiments, and the complementarity of gamma-ray measurements with other indirect, direct or accelerator-based searches. We conclude that any comprehensive search for dark matter should include gamma-ray observations, both to identify the dark matter particle (through the characteristics of the gamma-ray spectrum) and to measure the distribution of dark matter in galactic halos.

    Jupiter's satellite Io is the most geologically dynamic solid body in the Solar System. Io undergoes severe tidal heating, induced by the orbital eccentricity forced by Jupiter and the 4:2:1 Laplace resonance between Io, Europa, and Ganymede. Io's high global heat flow (>2 W m-2, compared to the 0.06 W m-2 average for Earth) presages an extremely rich array of geophysical, geological, geochemical, and atmospheric phenomena operating at a scale not currently seen active anywhere else in our Solar System. Thus we are not restricted, as on other planetary bodies, to reconstructing processes from their long-dead remains. Io also is the main source of neutral gas, plasma, and dust to the Jovian magnetosphere. And importantly, Io is the best place in the Solar System to study the effects of tidal heating. Testing models of tidal heating on Io has implications for many satellites in our own Solar System, and to the possibility of expanded habitability zones in extrasolar systems. Io's history is directly linked to the evolution of the one of most promising sites for extraterrestrial life, Europa. By studying the time-variable orbital and thermal evolution of Io, we also gain a better understanding of time-variable tidal heating of Europa, with obvious implications for the sustainability of its putative subsurface ocean and history of habitability. An Io-dedicated mission that operates in the 2013-2022 timeframe could identify key parameters involved in Europa’s orbital-thermal evolution, which can be further investigated by the NASA-ESA Europa-Jupiter System Mission's (EJSM) orbiters when they enter the Jovian system in 2025. This presentation will review the science objectives and proposed mission concepts for future exploration of Io in the next decade and beyond. We recommend specific mission concepts and instruments be implemented during the next Decadal Survey period. These include: 1) a Jupiter-orbiting spacecraft (Io Observer) of either Discovery-class or New

    Jupiter's satellite Io is the most geologically dynamic solid body in the Solar System, including Earth. Io undergoes severe tidal heating, induced by the orbital eccentricity forced by Jupiter and the 4:2:1 Laplace resonance between Io, Europa, and Ganymede. Global heat flow is estimated at >2 W/sq. m, compared to the 0.06 W/sq. m average for Earth. This one remarkable number presages a huge variety of interconnected phenomena operating at a scale not seen active anywhere else in our Solar System. Io offers an extremely rich array of geophysical, geological, geochemical, atmospheric, and magnetospheric phenomena. Diurnal tidal flexing amplitudes may reach 100 meters, dissipating huge amounts of heat in the interior, and resulting in extensive volcanic activity. Lavas of poorly known composition inundate the surface, while volcanic plumes feed a tenuous, inhomogeneous atmosphere controlled by a combination of volcanic outgassing, the formation of surface frosts and the sublimation of these frosts. Complementing Io's pervasive volcanic landforms, the surface is studded with some of the Solar System's highest and most dramatic mountains, and by scarps of both tectonic and erosional origin. As one of the most spectacular places in the Solar System, Io has unique public appeal, and Io exploration offers many opportunities to attract and engage public interest in planetary science. This poster highlights the science goals established to advance scientific understanding of Io for the next decade. We give a series of recommendations to the Planetary Decadal Survey Large Satellites Panel to advance Io exploration, including concepts for future Discovery- and New Frontiers-class missions, and ground- and spaced-based telescopic observations and instruments.

    Goat research in the United States has increased but at a rate less than that in production. Research on goat meat includes nutritional quality, packaging, color, sensory characteristics, and preslaughter management. Goat skins have value for leather, but quality of goat leather has not been extensively studied. Research in the production, quality, antibiotic residues, and sensory characteristics of goat milk and its products has aided development of the US dairy goat industry. Limited progress has been made in genetic improvement of milk or meat production. There is need to explore applications of genomics and proteomics and improve consistency in texture and functionality of goat cheeses. New goat meat and milk products are needed to increase demand and meet the diverse tastes of the American public. Despite research progress in control of mohair and cashmere growth, erratic prices and sale of raw materials have contributed to further declines in US production. Innovative and cooperative ventures are needed for profit sharing up to the consumer level. Internal parasites pose the greatest challenge to goat production in humid areas largely because of anthelmintic resistance. Study of alternative controls is required, including immunity enhancement via nutrition, vaccination, pasture management such as co-grazing with cattle, and genetic resistance. Similarly, the importance of health management is increasing related in part to a lack of effective vaccines for many diseases. Nutrition research should address requirements for vitamins and minerals, efficiencies of protein utilization, adjusting energy requirements for nutritional plane, acclimatization, and grazing conditions, feed intake prediction, and management practices for rapid-growth production systems. Moreover, efficient technology transfer methods are needed to disseminate current knowledge and that gained in future research.

      This article presents a discussion of nursing education development in the People's Republic of China in its historical, economic and sociopolitical contexts.   China has a population of 1·3 billion with about 2·18 million nurses. With the recent surging economic and social development in China, nursing education has undergone transformation changes in the past two decades.   Online bibliographical databases from 1990 to 2010 were searched including CINAHL, MEDLINE, Wan Fang Data and Chinese National Knowledge Infrastructure. Search terms included nursing education, China and development.   Thematic analysis and narrative synthesis were used to identify and report themes from literature.   Database searches yielded 1674 papers, and 34 met the inclusion criteria for review. The standard of nursing education varies greatly in different parts of China, because of its huge size and population, with pre-registration programmes offered at the secondary, associate degree and baccalaureate level. Multi-level nursing education is one of the major barriers for professional development. There is a need to upgrade the pre-registration education to at least associate degree level. There is also a need to enhance graduate nursing education at master and doctoral level to prepare advanced practice nurses, nurse scientists and nursing faculty. conclusion:  The challenges for nursing education development in China are echoed and encountered in many parts of the world. The experience in China and the lessons learned would be relevant to developing countries. Nursing in China must continue to develop in parallel to international trends. Promoting communication and maintaining international links are important for the global development of nursing practice. © 2011 Blackwell Publishing Ltd.

    To mitigate the damage effects of earthquakes in urban areas and particularly in historical centres prone to high seismic hazard is an important task to be pursued. As a matter of fact, seismic history throughout the world informs us that earthquakes have caused deep changes in the ancient urban conglomerations due to their high building vulnerability. Furthermore, some quarters can be exposed to an increase of seismic actions if compared with adjacent areas due to the geological and/or topographical features of the site on which the historical centres lie. Usually, the strategies aimed to estimate the local seismic hazard make only use of the geological-geophysical surveys. Thorough this approach we do not draw any lesson from what happened as a consequences of past earthquakes. With this in mind, we present the results of a joined use of historical data and traditional geological-geophysical approach to analyse the effects of possible future earthquakes in historical centres. The research activity discussed here is arranged into a joint collaboration between the Department of Civil Protection of the Presidency of Council of Ministers, the Institute of Environmental Geology and Geoengineering and the Institute of Archaeological and Monumental Heritage of the National (Italian) Research Council. In order to show the results, we discuss the preliminary achievements of the integrated study carried out on two historical towns located in Southern Apennines, a portion of the Italian peninsula exposed to high seismic hazard. Taking advantage from these two test sites, we also discuss some methodological implications that could be taken as a reference in the seismic microzonation studies.

    This is a report on the findings of the SNR/cosmic-ray working group for the white paper on the status and future of ground-based gamma-ray astronomy. The white paper is an APS commissioned document, and the overall version has also been released and can be found on astro-ph. This detailed section of the white paper discusses the status of past and current attempts to observe shell-type supernova remnants and diffuse emission from cosmic rays at GeV-TeV energies. We concentrate on the potential of future ground-based gamma-ray experiments to study the acceleration of relativistic charged particles which is one of the main unsolved, yet fundamental, problems in modern astrophysics. The acceleration of particles relies on interactions between energetic particles and magnetic turbulence. In the case of SNRs we can perform spatially resolved studies in systems with known geometry, and the plasma physics deduced from these observations will help us to understand other systems where rapid particle acceleration is believed to occur and where observations as detailed as those of SNRs are not possible.

    The number of cancer patients in Europe is rising and significant advances in basic and applied cancer research are making the provision of optimal care more challenging. The concept of cancer as a systemic, highly heterogeneous and complex disease has increased the awareness that quality cancer care should be provided by a multidisciplinary team (MDT) of highly qualified healthcare professionals. Cancer patients also have the right to benefit from medical progress by receiving optimal treatment from adequately trained and highly skilled medical professionals. Built on the highest standards of professional training and continuing medical education, medical oncology is recognised as an independent medical specialty in many European countries. Medical oncology is a core member of the MDT and offers cancer patients a comprehensive and systemic approach to treatment and care, while ensuring evidence-based, safe and cost-effective use of cancer drugs and preserving the quality of life of cancer patients through the entire 'cancer journey'. Medical oncologists are also engaged in clinical and translational research to promote innovation and new therapies and they contribute to cancer diagnosis, prevention and research, making a difference for patients in a dynamic, stimulating professional environment. Medical oncologists play an important role in shaping the future of healthcare through innovation and are also actively involved at the political level to ensure a maximum contribution of the profession to Society and to tackle future challenges. This position paper summarises the multifarious and vital contributions of medical oncology and medical oncologists to today's and tomorrow's professional cancer care.

  15. The Commission White Paper on a Strategy for a Future EU Chemicals Policy: the view of European companies of American parentage.

    After years of good service, EU legislation on chemicals is currently subject to a major review. This process, initiated by the Council of Ministers at Chester in April 1998, will soon lead to new legislative proposals. In the meantime, a review of the Commission's White Paper on "Strategy for a Future Chemicals Policy," published in February 2001, clearly shows that the regulatory landscape in this area will be significantly reshaped and that a new burden will be imposed on industry to demonstrate that the production and use of chemicals indeed conform to high standards of protection of human health and the environment. In the view of industry, on both sides of the Atlantic, while the objectives of the proposed reform can be supported, the measures proposed in the White Paper to implement these objectives are not properly balanced and will lead to substantial societal and economic drawbacks, unless significant adjustments are made. The purpose of this article is to present the pitfalls and difficulties of the reform as they are perceived by the EU Committee of the American Chamber of Commerce in Brussels, an organization that regroups about 150 European companies of American parentage, belonging to a broad range of European business sectors, including producers and users of chemicals. In view of the transatlantic and cross-business character of its membership, the EU Committee offers a different perspective on the debate.

    The oceanographic community routinely collects time-series data of hydrographic, current velocity, and other basic physical, chemical, and biological properties of the marine environment. Such data are essential for establishing baseline characteristics of marine and estuarine ecosystems. However, the task of taking the raw data files as downloaded from a variety of instruments from multiple manufacturers, and turning it into data in a form that can be used to answer specific research questions, can be highly complex and time-consuming. To illustrate some of these complexities, we have thoroughly documented the sequence of data processing steps for a small coastal ocean observing system 25 km southwest of the mouth of Mobile Bay, Alabama, that the Dauphin Island Sea Lab has been operating since 2004. The goal was to produce documentation in sufficient detail to achieve full science reproducibility for all studies that include data from this system, in accordance with best practices established by EarthCube OntoSoft's Geoscience Papers of the Future (GPF) Initiative.

    Land cover is one of the most important conditioning factors in landslide susceptibility analysis. Usually it is considered as a static factor, but it has proven to be dynamic, with changes occurring even in few decades. In this work the influence of land cover changes on landslide susceptibility are analyzed for the past and for future scenarios. For the application, an area representative of the hilly-low mountain sectors of the Italian Southern Apennines was chosen (Rivo basin, in Molise Region). With this purpose landslide inventories and land cover maps were produced for the years 1954, 1981 and 2007. Two alternative future scenarios were created for 2050, one which follows the past trend (2050-trend), and another one more extreme, foreseeing a decrease of forested and cultivated areas (2050-alternative). The landslide susceptibility analysis was performed using the Spatial Multi-Criteria Evaluation method for different time steps, investigating changes to susceptibility over time. The results show that environmental dynamics, such as land cover change, affect slope stability in time. In fact there is a decrease of susceptibility in the past and in the future 2050-trend scenario. This is due to the increase of forest or cultivated areas, that is probably determined by a better land management, water and soil control respect to other land cover types such as shrubland, pasture or bareland. Conversely the results revealed by the alternative scenario (2050-alternative), show how the decrease in forest and cultivated areas leads to an increase in landslide susceptibility. This can be related to the assumed worst climatic condition leading to a minor agricultural activity and lower extension of forested areas, possibly associated also to the effects of forest fires. The results suggest that conscious landscape management might contribute to determine a significant reduction in landslide susceptibility. Copyright © 2017 Elsevier B.V. All rights reserved.

    Recently initiated collaborative research project is presented. Its main objective is to develop high spatial and temporal resolution datasets for studying the ongoing and future climate changes in Siberia, caused by global and regional processes in the atmosphere and the ocean. This goal will be achieved by using a set of regional and global climate models for the analysis of the mechanisms of climate change and quantitative assessment of changes in key climate variables, including analysis of extreme weather and climate events and their dynamics, evaluation of the frequency, amplitude and the risks caused by the extreme events in the region. The main practical application of the project is to provide experts, stakeholders and the public with quantitative information about the future climate change in Siberia obtained on the base of a computational web- geoinformation platform. The thematic platform will be developed in order to facilitate processing and analysis of high resolution georeferenced datasets that will be delivered and made available to scientific community, policymakes and other end users as a result of the project. Software packages will be developed to implement calculation of various climatological indicators in order to characterize and diagnose climate change and its dynamics, as well as to archive results in digital form of electronic maps (GIS layers). By achieving these goals the project will provide science based tools necessary for developing mitigation measures for adapting to climate change and reducing negative impact on the population and infrastructure of the region. Financial support of the computational web- geoinformation platform prototype development by the RF Ministry of Education and Science under Agreement 14.613.21.0037 (RFMEFI61315X0037) is acknowledged.

    2016-01-01

    Neuropyschological dysfunction, ranging from mild cerebral indicators to dementia has been a consistent part of the medical picture of HIV/AIDS. However, advances in medical supervision, particularly as a result of antiretroviral (ARV) treatment, have resulted in some mitigation of the neuropsychological effects of HIV and necessitate re-evaluation of the pattern and nature of HIV-related cognitive or mental deficits. The associated enhancements in morbidity and mortality that have occurred as a result of ARV medication have led to a need for interventions and programs that maintain behaviors that are healthy and stop the resurgence of the risk of HIV transmission. Risk factors such as mental illness and substance use that may have contributed to the initial infection with HIV still need consideration. These risk factors may also increase neuropsychological dysfunction and impact observance of prevention for treatment and recommendations. Explicitly, a better comprehension of the role of substance use on the progression of HIV-related mental decline can enlighten management and evaluation of persons living with HIV with concurrent disorders of substance use. This review provides a summary of the neurophyschology of substance use and HIV and the existing research that has looked at the effects of both substance use and HIV disease on neurophyscological function and suggestions for future research and treatment.

    Although capacity credits for wind power have been embodied in power systems in the U.S. and Europe, the current planning framework for electricity in China continues to treat wind power as a nondispatchable source with zero contribution to firm capacity. This study adopts a rigorous reliability model for the electric power system evaluating capacity credits that should be recognized for offshore wind resources supplying power demands for Jiangsu, China. Jiangsu is an economic hub located in the Yangtze River delta accounting for 10% of the total electricity consumed in China. Demand for electricity in Jiangsu is projected to increase from 331 TWh in 2009 to 800 TWh by 2030. Given a wind penetration level of 60% for the future additional Jiangsu power supply, wind resources distributed along the offshore region of five coastal provinces in China (Shandong, Jiangsu, Shanghai, Zhejiang, and Fujian) should merit a capacity credit of 12.9%, the fraction of installed wind capacity that should be recognized to displace coal-fired systems without violating the reliability standard. In the high-coal-price scenario, with 60% wind penetration, reductions in CO2 emissions relative to a business as usual reference could be as large as 200.2 million tons of CO2 or 51.8% of the potential addition, with a cost for emissions avoided of $29.0 per ton.

  3. Antarctic notothenioid fish: what are the future consequences of 'losses' and 'gains' acquired during long-term evolution at cold and stable temperatures?

    Antarctic notothenioids dominate the fish fauna of the Southern Ocean. Evolution for millions of years at cold and stable temperatures has led to the acquisition of numerous biochemical traits that allow these fishes to thrive in sub-zero waters. The gain of antifreeze glycoproteins has afforded notothenioids the ability to avert freezing and survive at temperatures often hovering near the freezing point of seawater. Additionally, possession of cold-adapted proteins and membranes permits them to sustain appropriate metabolic rates at exceptionally low body temperatures. The notothenioid genome is also distinguished by the disappearance of traits in some species, losses that might prove costly in a warmer environment. Perhaps the best-illustrated example is the lack of expression of hemoglobin in white-blooded icefishes from the family Channichthyidae. Loss of key elements of the cellular stress response, notably the heat shock response, has also been observed. Along with their attainment of cold tolerance, notothenioids have developed an extreme stenothermy and many species perish at temperatures only a few degrees above their habitat temperatures. Thus, in light of today's rapidly changing climate, it is critical to evaluate how these extreme stenotherms will respond to rising ocean temperatures. It is conceivable that the remarkable cold specialization of notothenioids may ultimately leave them vulnerable to future thermal increases and threaten their fitness and survival. Within this context, our review provides a current summary of the biochemical losses and gains that are known for notothenioids and examines these cold-adapted traits with a focus on processes underlying thermal tolerance and acclimation capacity. © 2015.

    Traditional definitions of risk partition concern into the probability of occurrence and the consequence of the event. Most safety analyses focus on probabilistic assessment of an occurrence and the amount of some measurable result of the event, but the real meaning of the ``consequence`` partition is usually afforded less attention. In particular, acceptable social consequence (consequence accepted by the public) frequently differs significantly from the metrics commonly proposed by risk analysts. This paper addresses some of the important system development issues associated with consequences, focusing on ``high consequence operations safety.``

    Genetic factors have direct and indirect impacts in the viability of endangered species. Assessing their genetic diversity levels and population structure is thus fundamental for conservation and management. In this paper we use mitochondrial and nuclear markers to address phylogeographic and demographic data on the critically endangered Anaecypris hispanica, using a broad sampling set which covered its known distribution area in the Iberian Peninsula. Our results showed that the populations of A. hispanica are strongly differentiated (high and significant ФST and FST values, corroborated by the results from AMOVA and SAMOVA) and genetically diversified. We suggest that the restricted gene flow between populations may have been potentiated by ecological, hydrological and anthropogenic causes. Bayesian skyline plots revealed a signal for expansion for all populations (tMRCA between 68kya and 1.33Mya) and a genetic diversity latitudinal gradient was detected between the populations from the Upper (more diversified) and the Lower (less diversified) Guadiana river basin. We postulate a Pleistocenic westwards colonization route for A. hispanica in the Guadiana river basin, which is in agreement with the tempo and mode of paleoevolution of this drainage. The colonization of River Guadalquivir around 60kya with migrants from the Upper Guadiana, most likely by stream capture, is also suggested. This study highlights the view that critically endangered species facing range retreats (about 47% of its known populations have disappeared in the last 15years) are not necessarily small and genetically depleted. However, the extinction risk is not negligible since A. hispanica faces the combined effect of several deterministic and stochastic negative factors and, moreover, recolonization events after localized extinctions are very unlikely to occur due to the strong isolation of populations and to the patchily ecologically-conditioned distribution of fish. The inferred species

  19. It was a first class start which laid the basis for a promising future: Experience from comparative studies on gravity related behavior in animals and consequences for future experiments

    NASA Astrophysics Data System (ADS)

    Horn, Eberhard R.

    2000-01-01

    The main title was chosen in imitation of the headline of a lecture given by H. S. Wolff at the ESA-Symposium ``Life Odyssey'' in Maastricht/NL (1999) to contrast his pessimistic view of the science output from biological microgravity studies during the past 25 years with an optimistic view of the author who had the opportunity for studies on the gravity sensory systems of developing vertebrates and insects during the space missions STS-55, STS-84, and STS-90, and who was stimulated by this experience to undertake any effort to extend these studies on the International Space Station ISS. We studied compensatory eye and head movements induced by a lateral roll of the animals, and we found that exposure to both microgravity and hypergravity affect their development. Future studies have to consider long-term exposures to altered gravitational conditions to find answers to two questions, the mechanisms of adaptation during exposure, and the degree of residual effects after becoming an adult animal and also after re-entry to IG-conditions. The main hypothesis on the development of animals in space is that a fertilized egg will be converted to a normal adult animal guided by physiological and morphological set-points which represent the genetic program. In case of developmental retardations or accelerations or otherwise occurring deviations from normal structural and physiological development during specific periods of the embryonic and postembryonic life, these genetically defined supervisors activate readaptive mechanisms which direct the developmental processes towards normality, i.e., stability. Thus, an orbit-stabilized organism will be dramatically disturbed after return to Earth. Because this failure will need support to reach neuronal stability, research has also to consider the analysis of mechanisms which are able to overcome these disturbances. This research will open the door to applications because it forms a bridge to human medicine with its analytical

  7. Phenomenological consequences of supersymmetry

    Hinchliffe, I.; Littenberg, L.

    1982-01-01

    This report deals with the phenomenological consequences of supersymmetric theories, and with the implications of such theories for future high energy machines. It is concerned only with high energy predictions of supersymmetry; low energy consequences (for example in the K/sub o/anti K/sub o/ system) are discussed in the context of future experiments by another group, and will be mentioned briefly only in the context of constraining existing models. However a brief section is included on the implication for proton decay, although detailed experimental questions are not discussed. The report is organized as follows. Section I consists of a brief review of supersymmetry and the salient features of existing supersymmetric models; this section can be ignored by those familiar with such models since it contains nothing new. Section 2 deals with the consequences for nucleon decay of SUSY. The remaining sections then discuss the physics possibilities of various machines; e anti e in Section 3, ep in Section 4, pp (or anti pp) colliders in Section 5 and fixed target hadron machines in Section 6.

  8. Cultural consequences of miscarriages of justice.

    PubMed

    Cole, Simon A

    2009-01-01

    Social science scholarship has tended to focus more on the causes than the consequences of miscarriages of justice. Within the literature on consequences, the overwhelming emphasis has been on individual consequences: psychological and material impacts on the wrongly convicted individual and, in some cases, other indirectly impacted individuals such as family members of the wrongly convicted and victims of the true perpetrator's future crimes. Some attention has been devoted to social harms, the impact of miscarriages of justice on the broader society within which they are situated, such as the undermining of the legitimacy of the criminal justice system. This paper focuses on what are called here cultural consequences of miscarriages of justice: the way in which some high-profile miscarriages of justice can shape the public's beliefs about some of the most basic "facts" about crime, such as the nature, prevalence, or even existence of certain categories of crime and the types of individual who tend to perpetrate particular types of crime. In this way, the paper argues, miscarriages of justice may have hitherto underexplored consequences: reshaping, based on false premises, the public's belief about the very nature of crime itself. This paper discusses three cases studies of miscarriages of justice that for varying periods of time created widespread false beliefs about the nature of crime in large segments of the public. The paper concludes by noting that the "righting" of these false beliefs was in most cases fortuitous. This suggests that unexposed miscarriages of justice may still be shaping popular beliefs about the nature of crime, and aspects of the public's current conception of crime may yet be based on false premises.

  9. Consortium for Electric Reliability Technology Solutions Grid of the Future White Paper on Review of Recent Reliability Issues and Systems Events

    SciTech Connect

    Hauer, John F.; Dagle, Jeffery E.

    1999-12-01

    This report is one of six reports developed under the U.S. Department of Energy (DOE) program in Power System Integration and Reliability (PSIR). The objective of this report is to review, analyze, and evaluate critical reliability issues demonstrated by recent disturbance events in the North America power system. Eleven major disturbances are examined, most occurring in this decade. The strategic challenge is that the pattern of technical need has persisted for a long period of time. For more than a decade, anticipation of market deregulation has been a major disincentive to new investments in system capacity. It has also inspired reduced maintenance of existing assets. A massive infusion of better technology is emerging as the final option to continue reliable electrical services. If an investment in better technology will not be made in a timely manner, then North America should plan its adjustments to a very different level of electrical service. It is apparent that technical operations staff among the utilities can be very effective at marshaling their forces in the immediate aftermath of a system emergency, and that serious disturbances often lead to improved mechanisms for coordinated operation. It is not at all apparent that such efforts can be sustained through voluntary reliability organizations in which utility personnel external to those organizations do most of the technical work. The eastern interconnection shows several situations in which much of the technical support has migrated from the utilities to the Independent System Operator (ISO), and the ISO staffs or shares staff with the regional reliability council. This process may be a natural and very positive consequence of utility restructuring. If so, the process should be expedited in regions where it is less advanced.

    surgery training could occupy the area between general surgery residency and further subspecialty training as seen in the graph below. Visually, we are trying to define the red hash mark area. This is challenging as the inner border with core general surgery is ill defined and interpreted differently by various stakeholders. Similarly, the outer border of the red hash marks, which defines areas that require a surgical subspecialist, is also not clear. Inevitably, overlap exists in the care of these patients and is influenced by the complexity of the underlying disease presentations. The concept is noble, but the future is unclear. Challenges and uncertainties include whether the Certificate of Focused Expertise will go forward, and what the RRC and ABS might decide on the structure of General Surgery training. Funding and the ability to offer autonomy during training are additional challenges in today's training environment. Currently, the ABS is considering a "Core Plus" concept, though what is "the Core" and what is the "Plus" are not yet determined, and these concepts have been promoted for years. Whether training becomes 4 +1, or 4 +1+1, 5+1 or some other model continues to be discussed. We, the Task Force of Advanced GI Surgery Training, have drafted a vision of what advanced GI training could/should look like to help guide the ABMS/ABS/RRC/ACGME as they contemplate surgery residency redesign goals. Despite the uncertainty, we will develop the curriculum, milestones, and case requirements for advanced GI surgery training, to not only provide this vision but so that an advanced GI training program is ready to go, to be plugged in to whatever the future structure for surgical training may be.

    To identify types of clinical unintended adverse consequences resulting from computerized provider order entry (CPOE) implementation. An expert panel provided initial examples of adverse unintended consequences of CPOE. The authors, using qualitative methods, gathered and analyzed additional examples from five successful CPOE sites. Using a card sort method, the authors developed a categorization scheme for the 79 unintended consequences initially identified and then iteratively modified the scheme to categorize 245 additional adverse consequences resulting from fieldwork. Because the focus centered on consequences requiring prevention or remedial action, the authors did not further analyze reported unintended beneficial (positive) consequences. Unintended adverse consequences (UACs) fell into nine major categories (in order of decreasing frequency): 1) more/new work for clinicians; 2) unfavorable workflow issues; 3) never ending system demands; 4) problems related to paper persistence; 5) untoward changes in communication patterns and practices; 6) negative emotions; 7) generation of new kinds of errors; 8) unexpected changes in the power structure; and 9) overdependence on the technology. Clinical decision support features introduced many of these unintended consequences. Identifying and understanding the types and in some instances the causes of unintended adverse consequences associated with CPOE will enable system developers and implementers to better manage implementation and maintenance of future CPOE projects.

    Ischaemic heart disease and the heart failure that often results, remain the leading causes of death and disability in Europe and worldwide. As such, in order to prevent heart failure and improve clinical outcomes in patients presenting with an acute ST-segment elevation myocardial infarction and patients undergoing coronary artery bypass graft surgery, novel therapies are required to protect the heart against the detrimental effects of acute ischaemia/reperfusion injury. During the last three decades, a wide variety of ischaemic conditioning strategies and pharmacological treatments have been tested in the clinic - however, their translation from experimental to clinical studies for improving patient outcomes has been both challenging and disappointing. Therefore, in this Position Paper of the European Society of Cardiology Working Group on Cellular Biology of the Heart, we critically analyse the current state of ischaemic conditioning in both the experimental and clinical settings, provide recommendations for improving its translation into the clinical setting, and highlight novel therapeutic targets and new treatment strategies for reducing acute myocardial ischaemia/reperfusion injury.

    Paper is ubiquitous in everyday life and a truly low-cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed.

    Gregory, Julie J.; Harper, Frederick T.

    1999-07-28

    The joint USNRC/CEC consequence uncertainty study was chartered after the development of two new probabilistic accident consequence codes, MACCS in the U.S. and COSYMA in Europe. Both the USNRC and CEC had a vested interest in expanding the knowledge base of the uncertainty associated with consequence modeling, and teamed up to co-sponsor a consequence uncertainty study. The information acquired from the study was expected to provide understanding of the strengths and weaknesses of current models as well as a basis for direction of future research. This paper looks at the elicitation process implemented in the joint study and discusses some of the uncertainty distributions provided by eight panels of experts from the U.S. and Europe that were convened to provide responses to the elicitation. The phenomenological areas addressed by the expert panels include atmospheric dispersion and deposition, deposited material and external doses, food chain, early health effects, late health effects and internal dosimetry.

    The demands for high resolution and issues of line edge roughness require a reconsideration of current resist design strategies. In particular, EUV lithography will provide an opportunity to examine new resist concepts including new elemental compositions and low molar mass resists or molecular resists. In the former case, resist compositions incorporating elements such as silicon and boron have been explored for EUV resists and will be described. In an example of the latter case, molecular glass resists have been designed using synthetic architectures in globular and core-arm forms ranging from one to multiple arms. Moreover, our studies include a series of ring and irregularly shaped small molecules modified to give imaging performance. These materials have been explored to improve line edge roughness (LER) compared to common polymer resists. Several examples of polymeric and molecular glass resists will be described. Several compositions showed high glass transition temperatures (Tg) of ~ 120°C and possessed no crystallinity as seen from XRD studies.

    While histopathology of excised tissue remains the gold standard for diagnosis, several new, non-invasive diagnostic techniques are being developed. They rely on physical and biochemical changes that precede and mirror malignant change within tissue. The basic principle involves simple optical techniques of tissue interrogation. Their accuracy, expressed as sensitivity and specificity, are reported in a number of studies suggests that they have a potential for cost effective, real-time, in situ diagnosis. We review the Third Scientific Meeting of the Head and Neck Optical Diagnostics Society held in Congress Innsbruck, Innsbruck, Austria on the 11th May 2011. For the first time the HNODS Annual Scientific Meeting was held in association with the International Photodynamic Association (IPA) and the European Platform for Photodynamic Medicine (EPPM).

    In many scientific societies, presentation by poster has become a popular alternative to oral delivery for contributed papers at major meetings. This has not been so in the AGU. My purpose in this 'editorial' is to acquaint the AGU membership with some of the advantages of the poster paper as an occasional alternative to the 10-minute talk.The main advantage for the author of a poster paper is the opportunity for interaction with an interested audience for a 3 hour period. Significant feedback from the audience is a bonus that gives the author a better understanding of his own work and how to explain it, both orally and in print. Those of us who have tried poster presentation have found it to be a very positive experience.

    We developed a new protein crystallization method that incorporates paper. A small piece of paper, such as facial tissue or KimWipes, was added to a drop of protein solution in the traditional sitting drop vapor diffusion technique, and protein crystals grew by incorporating paper. By this method, we achieved the growth of protein crystals with reducing osmotic shock. Because the technique is very simple and the materials are easy to obtain, this method will come into wide use for protein crystallization. In the future, it could be applied to nanoliter-scale crystallization screening on a paper sheet such as in inkjet printing.

    This article relates the case of two young girls who became pregnant as a result of rape and their efforts to exercise their rights to terminate the pregnancy. The first victim was a 12-year-old girl from Bolivia and the second was Paulina, a 13-year-old resident of Baja California, Mexico. Though abortion is illegal in both countries, in the case of rape the procedure is "unpunishable" in Bolivia and legal in Mexico. Despite these laws, the girls, their families and their advocates contend repeatedly with local government and Catholic Church officials on the issue. Only the first victim successfully exercised her right to terminate her pregnancy through the efforts of her family and the decision of Penal Judge Luis Ledezma. This paper also highlights the need for reforms in the abortion law in both countries.

    Forecasts can be made for a range of probabilities based on logical decisions by world leaders during the next century, and an Austrian think tank, the International Institute for Applied Systems Analysis (IIASA), with the World Energy Council (WEC), has presented a range of six alternatives moving toward the next century. In all of those scenarios, the world will use a smaller percentage of oil than it does now, and in most, it will use a smaller percentage of gas, but the amounts of oil and gas will be greater than today's levels in most of those futures. In all six scenarios, population will grow from a 1990 level of 5.3 billion to 10.1 billion in 2050 and 11.7 billion 50 years later. And the paths for all six scenarios will be about the same through 2020, because of the long life of existing power plants and refineries. After that time, all scenarios move away from the existing strong reliance on oil and gas as a 53% owner of the total energy supply. To establish a baseline, coal had 24% of the market in 1990, and other sources had 23%. The three basic cases are: (A) a future of impressive technological improvements and consequent high economic growth; (B) a future with less ambitious, though perhaps more realistic, technological improvements, and consequently more intermediate economic growth; and (C) an ecologically driven future that includes substantial technological progress and unprecedented international co-operation centered explicitly on environmental protection and international equity. The paper discusses all three cases.

    BACKGROUND. In September 2008, under the French Presidency of the European Union and with the support of the Polish Minister of Health, a European Summit on Age-Related Disease was organised inWroclaw (Poland). At this meeting, European politicians, gerontologists and geriatricians gathered to discuss a common approach to future challenges related to age-related disease. Politicians and decision-makers from the European Union and Ministers of Health and their deputies from many European countries raised the problems and difficulties to be tackled in a growing population with a high burden of disease, and asked scientists to write a consensus document with recommendations for future actions and decisions. Scientists and clinicians worked in parallel in three different groups, on health promotion and preventive actions, basic research in age-related disease, and clinical aspects of disease in older people. Beforehand, the format of the paper with recommendations was discussed, and it was finally agreed that, for a better understanding by decision- makers, it would be divided in two different columns: one with facts that were considered settled and agreed by most experts (under the heading We know), and a second with recommendations related to each fact (We recommend). No limit on the number of topics to be discussed was settled. After careful and detailed discussion in each group, which in most cases included the exact wording of each statement, chairpersons presented the results in a plenary session, and new input from all participants was received, until each of the statements and recommendations were accepted by a large majority. Areas with no consensus were excluded from the document. Immediately after the Summit, the chairpersons sent the document both to the main authors and to a list of experts (see footnote) who had made presentations at the summit and agreed to review and critically comment on the final document, which is presented below.

    The development of two new probabilistic accident consequence codes, MACCS and COSYMA, was completed in 1990. These codes estimate the consequences from the accidental releases of radiological material from hypothesized accidents at nuclear installations. In 1991, the U.S. Nuclear Regulatory Commission and the European Commission began co-sponsoring a joint uncertainty analysis of the two codes. The ultimate objective of this joint effort was to systematically develop credible and traceable uncertainty distributions for the respective code input variables using a formal expert judgment elicitation and evaluation process. This paper focuses on the methods used in and results of this on-going joint effort.

  3. Ecological Consequences of Clonal Integration in Plants

    PubMed Central

    Liu, Fenghong; Liu, Jian; Dong, Ming

    2016-01-01

    Clonal plants are widespread throughout the plant kingdom and dominate in diverse habitats. Spatiotemporal heterogeneity of environment is pervasive at multiple scales, even at scales relevant to individual plants. Clonal integration refers to resource translocation and information communication among the ramets of clonal plants. Due to clonal integration, clonal plant species possess a series of peculiar attributes: plasticity in response to local and non-local conditions, labor division with organ specialization for acquiring locally abundant resources, foraging behavior by selective placement of ramets in resource-rich microhabitats, and avoidance of intraclonal competition. Clonal integration has very profound ecological consequences for clonal plants. It allows them to efficiently cope with environmental heterogeneity, by alleviating local resource shortages, buffering environmental stresses and disturbances, influencing competitive ability, increasing invasiveness, and altering species composition and invasibility at the community level. In this paper, we present a comprehensive review of research on the ecological consequences of plant clonal integration based on a large body of literature. We also attempt to propose perspectives for future research. PMID:27446093

    Selecting and developing materials for the future devices require a sound understanding of design requirements. Miniaturization of electronic devices, as commonly expressed by Moore Law, has involved the integration level. Increase of the level has caused some consequences in the design and selection of materials for interconnection. The present paper deals with the challenge of materials design and selection beyond the nanoscale limit and the ability of traditional materials to cope with. One of the emerging materials, i.e. Graphene, will be reviewed with particular reference to its characteristics and potentials for future interconnection.

    The Third Lord Rayleigh (1842-1919), aka John William Strutt, was among the most stellar physicists of the Nineteenth Century, in both theory and experiment. He spent most of his mature years in his own laboratory, self-funded, on his family estate. One of the consequences was the fact that all of his papers remained at the estate upon his death. After his son's (Robert John Strutt, 1875-1947) death both their scientific papers ended up on the auction block. (Robert John was himself an atmospheric physicist.) Part of the Strutt collection went to the Burndy Library of the Dibner Institute at MIT, but most landed in the library at the US Air Force Cambridge Research Laboratory (now the Air Force Research Laboratory at Hansom AFB), purchased from the auctioneer out of library funds, for 9,000. The individual most responsible for preserving these papers was John N. Howard, the laboratory Chief Scientist, who was a founding editor of the journal Applied Optics. Recently the authors examined first hand the Rayleigh papers. Included in these are a complete set of his handwritten scientific notes, taken over the period 1862-1919, from the time he was a student at Trinity College, Cambridge until just months before his death. We will show a number of interesting examples from these notes, including his first identification of argon, as well as some other fascinating items from the collection.

  9. Exploring the future with anticipatory networks

    NASA Astrophysics Data System (ADS)

    Skulimowski, A. M. J.

    2013-01-01

    This paper presents a theory of anticipatory networks that originates from anticipatory models of consequences in multicriteria decision problems. When making a decision, the decision maker takes into account the anticipated outcomes of each future decision problem linked by the causal relations with the present one. In a network of linked decision problems, the causal relations are defined between time-ordered nodes. The scenarios of future consequences of each decision are modeled by multiple vertices starting from an appropriate node. The network is supplemented by one or more relations of anticipation, or future feedback, which describe a situation where decision makers take into account the anticipated results of some future optimization problems while making their choice. So arises a multigraph of decision problems linked causally and by one or more anticipation relation, termed here the anticipatory network. We will present the properties of anticipatory networks and propose a method of reducing, transforming and using them to solve current decision problems. Furthermore, it will be shown that most anticipatory networks can be regarded as superanticipatory systems, i.e. systems that are anticipatory in the Rosen sense and contain a future model of at least one other anticipatory system. The anticipatory networks can also be applied to filter the set of future scenarios in a foresight exercise.

    During the week 8-12 April 1996, an international conference summing up the consequences of the Chernobyl disaster after one decade took place in Vienna. Organizers were the European Commission (EC), the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO) (EC/IAEA/WHO 1996). One of the authors, A. Kaul, presented the outcome of the conference as given below to the IPRA 9 congress which was held in Vienna the following week. Two caveats have to be mentioned here: firstly, only facts actually reported and reviewed at the conference can be accounted for, and, secondly, according to the groundrules of the conference, the deadline for the background papers of the conference was the 9 February 1996, meaning that facts materializing after that time are not covered in this paper. The same applied to information given at the conference that was not properly reviewed and published. Reports, for example, given at the conference on an observed increase of thyroid cancers and leukemia among liquidators and of diabetes mellitus among children are not yet substantiated and are, therefore, not yet recognized as consequences. If corroborated, and it is obvious that all higher exposed groups should be closely monitored in the future, an update on the consequences will have to take this into account. 2 refs., 1 fig., 4 tabs.

    Health outcomes and, in particular, patient health outcomes have become a driving force within health-care delivery. Little emphasis has been placed on the potential health consequences for nurses providing care and caring within the health-care system. Compassion fatigue (or secondary traumatic stress) has emerged as a natural consequence of caring for clients who are in pain, suffering or traumatized. This paper sheds light on how nursing work might impact the health of nurses by exploring the concept of compassion fatigue. Limitations of current instruments to measure compassion fatigue are highlighted, and suggestions for future direction are presented.

  15. Introduction to Jebsen's paper

    NASA Astrophysics Data System (ADS)

    Deser, S.

    2005-12-01

    Brief comment on a 1921 paper by Jebsen. This work provides the first published proof of “Birkhoff's” theorem. The author, who seems to have been an undergraduate at the time (tragically, he died shortly afterwards) understood (as did many others) that Einstein's equations reduced considerably in a “minimal,” namely two-component, metric in a simple gauge such as Schwarzschild's; a good part of the paper is devoted to deriving this interval form. The originality of his work lies instead in showing that time-independence of the exterior Schwarzschild solution need not be assumed, but is a consequence of Einstein's equations. From a modern perspective, it is a bit surprising that this result was not found earlier: for example, Einstein studied the spherical solution in the linearized theory, whose kinship to Maxwell's might have suggested the obvious parallel to charge conservation. In current language, the theorem states gauge theories forbid monopole radiation because they have no helicity zero modes. Editor's note: Further references to early derivations of “Birkhoff's” theorem can be found in [1] and [2] while [3] is one of the few papers that calls it “Jebsen-Birkhoff.” Since few's was written a more detailed biography of Jebsen has now appeared: gr-qc/0508163, by Johausen & Ravulal.

    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

    A short overview of main characteristics of the impactor population from which major terrestrial impacts originated is given. This population includes the objects that may hit the Earth in the future (potentially hazardous asteroids, PHAs). An impact frequency (a way of measuring the probability of a given collision) versus impact energy (an index of the impact consequences) relationship is described on the basis of this analysis. The current state of actions started planetwide by the most developed countries to face the threat represented by an asteroid collision with the Earth is summarized. The 'Torino scale', which assesses the risks connected with a discovery of a PHA in a simple and clear way is finally described. To cite this article: M. Fulchignoni, M.A. Barucci, C. R.

    2016-01-01

    The aim of this study was to examine the relationship between individual attributes and envy, and to determine how envy may impact personal response variables in the workplace. To address these issues we apply Vecchio's theory on antecedents and consequences of envy (1995) as a theoretical framework. The present study relied on a cross-sectional measurement design. A total of 135 leaders and 772 followers employed in business organizations participated. SEM analysis shows that span of supervision serves as an important antecedent of envy, where span of supervision is significantly associated to envy via supportive leadership. Furthermore, envy seems to be indirectly and negatively related to self-esteem via distress and directly related to social loafing. The implications of these findings are discussed, and suggestions for future research are outlined.

    BP Exploration currently has an interest in hundreds of kilometers of operating multiphase flowlines. Most of the company`s proposed field developments also involve multiphase flowlines. A large number of these do or will experience slug flow, either as the normal flow regime, or as a result of transient behavior. Data on flow regime and slug flow characteristics have been collected from many lines over the past 8 years. Information on slug characteristics from a number of different systems is presented in this paper, including velocity, length and holdup. Some unfavorable consequences of slug flow on both process performance and system integrity are highlighted, including plant shutdowns and mechanical damage. The need to be able to predict slug flow for the design of future systems, and to advise the operators of existing systems, remains a high priority for R and D activities, as ever longer and more complex multiphase systems are proposed. BP`s latest slug frequency method is described, followed by guidelines for pipework layout, and comments on current R and D on corrosion in multiphase flow.

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.

  8. Intuitions, principles and consequences

    2001-01-01

    Some approaches to the assessment of moral intuitions are discussed. The controlled ethical trial isolates a moral issue from confounding factors and thereby clarifies what a person's intuition actually is. Casuistic reasoning from situations, where intuitions are clear, suggests or modifies principles, which can then help to make decisions in situations where intuitions are unclear. When intuitions are defended by a supporting principle, that principle can be tested by finding extreme cases, in which it is counterintuitive to follow the principle. An approach to the resolution of conflict between valid moral principles, specifically the utilitarian and justice principles, is considered. It is argued that even those who justify intuitions by a priori principles are often obliged to modify or support their principles by resort to the consideration of consequences. Key Words: Intuitions • principles • consequences • utilitarianism PMID:11233371

    Overtraining refers to prolonged fatigue and reduced performance despite increased training. Its roots include muscle damage, cytokine actions, the acute phase response, improper nutrition, mood disturbances, and diverse consequences of stress hormone responses. The clinical features are varied, non-specific, anecdotal and legion. No single test is diagnostic. The best treatment is prevention, which means (1) balancing training and rest, (2) monitoring mood, fatigue, symptoms and performance, (3) reducing distress and (4) ensuring optimal nutrition, especially total energy and carbohydrate intake.

    The ability to put cutting edge technology on paper—not in words but in a working physical form—has been attracting an increasing number of researchers over the past decade. Paper has many advantages that make it attractive for flexible electronics: it is relatively environmentally benign; it is renewable; it can be recycled; it is light weight; production processes for paper are well advanced; and it is inexpensive. This special issue, with guest editors Ronald Österbacka from Åbo Akademi University in Finland and Jin-Woo Han from the NASA AMES Research Center, features some of the latest in paper electronics research, including developments towards applications in displays, sensing and alternative energy sources, as well as fundamental studies to further our understanding of how paper can be most effectively used in electronics. As Andrew Steckl and colleagues in the US point out, 'Cellulose-based paper substrates were implemented as an electronic substrate as early as 1969, with most advancement occurring in the past decade largely due to technology improvements in thin film deposition and organic materials' [1, 2]. They report a detailed comparison between paper, standard liquid crystal display rigid glass and flexible glass for hosting pentacene organic thin film transistors, and obtain promising results for future paper-based devices. As most meaningful electronic devices rely on transistors to function, transistors feature quite prominently in this special issue. Rodrigo Martins and colleagues in France and Portugal study the effect of fibre type, structure and dimension on paper-based transistors and reveal further insights into how paper properties affect device performance [3]. Qing Wan and colleagues in China bring the state of the art in transistor technology to paper substrates [4], fabricating indium-zinc-oxide (IZO)-based protonic/electronic hybrid thin film transistors on paper and showing that they can be used as artificial synapses.

    The Internet represents a different type of technology for publishers of scientific, technical, and medical journals. It is not a technology that sustains current markets and creates new efficiencies but is, rather, a disruptive technology that could radically alter market forces, profit expectations, and business models. This paper is a translation and amplification of the research done in this area, applied to a large-circulation new science journal, Pediatrics. The findings suggest that the journal of the future will be electronic, have a less volatile cost structure, be supported more by services than by content, be less able to rely on subscription revenues, and abandon certain elements of current value networks. It also provides a possible framework for other publishers to use to evaluate their own journals relative to this disruptive technology. PMID:10833160

These figures, from an unselected community sample, were higher than had been expected; in addition, evidence of a significant mortality of young men from this cause was obtained. S. haematobium in Tanzania is therefore of considerable public health importance. PMID:5296234

    2016-01-01

    The Future Aviation Safety Team (FAST) is a multidisciplinary international group of aviation professionals that was established to identify possible future aviation safety hazards. The principle was adopted that future hazards are undesirable consequences of changes, and a primary activity of FAST became identification and prioritization of possible future changes affecting aviation. Since 2004, FAST has been maintaining a catalogue of "Areas of Change" (AoC) that could potentially influence aviation safety. The horizon for such changes is between 5 to 20 years. In this context, changes must be understood as broadly as possible. An AoC is a description of the change, not an identification of the hazards that result from the change. An ex-post analysis of the AoCs identified in 2004 demonstrates that changes catalogued many years previous were directly implicated in the majority of fatal aviation accidents over the past ten years. This paper presents an overview of the current content of the AoC catalogue and a subsequent discussion of aviation safety concerns related to these possible changes. Interactions among these future changes may weaken critical functions that must be maintained to ensure safe operations. Safety assessments that do not appreciate or reflect the consequences of significant interaction complexity will not be fully informative and can lead to inappropriate trade-offs and increases in other risks. The FAST strongly encourages a system-wide approach to safety risk assessment across the global aviation system, not just within the domain for which future technologies or operational concepts are being considered. The FAST advocates the use of the "Areas of Change" concept, considering that several possible future phenomena may interact with a technology or operational concept under study producing unanticipated hazards.

  2. Introduction: consequences of terrorism.

    PubMed

    Noji, Eric K

    2003-01-01

    Recent acts of terrorism have ranged from the dissemination of anthrax spores to intentional contamination of food to the release of chemical weapons to suicide attacks using explosives. The prediction of such events is difficult, if not impossible. The recent attacks that have generated massive numbers of injured and dead may signal the crossing of a new threshold from multi-casualty events to the use of weapons of mass destruction. Consequently, the medical and healthcare infrastructure must be able to prevent and treat illness and injury resulting from such events. Thus, a first step in improving the preparation for and responses to such events must include a sustained commitment to training physicians, nurses, identification specialists, pathologists, and other first responders. The rapid spread of SARS gives reason to believe that the distribution of such agents has potential advantages over the use of other weapons. Investments in the public health and healthcare systems provide the best defense against terrorism.

  3. Eusociality: origin and consequences.

    PubMed

    Wilson, Edward O; Hölldobler, Bert

    2005-09-20

    In this new assessment of the empirical evidence, an alternative to the standard model is proposed: group selection is the strong binding force in eusocial evolution; individual selection, the strong dissolutive force; and kin selection (narrowly defined), either a weak binding or weak dissolutive force, according to circumstance. Close kinship may be more a consequence of eusociality than a factor promoting its origin. A point of no return to the solitary state exists, as a rule when workers become anatomically differentiated. Eusociality has been rare in evolution, evidently due to the scarcity of environmental pressures adequate to tip the balance among countervailing forces in favor of group selection. Eusociality in ants and termites in the irreversible stage is the key to their ecological dominance and has (at least in ants) shaped some features of internal phylogeny. Their colonies are consistently superior to solitary and preeusocial competitors, due to the altruistic behavior among nestmates and their ability to organize coordinated action by pheromonal communication.

    Aneuploidy, or an aberrant karyotype, results in developmental disabilities and has been implicated in tumorigenesis. However, the causes of aneuploidy-induced phenotypes and the consequences of aneuploidy on cell physiology remain poorly understood. We have performed a metaanalysis on gene expression data from aneuploid cells in diverse organisms, including yeast, plants, mice, and humans. We found highly related gene expression patterns that are conserved between species: genes that were involved in the response to stress were consistently upregulated, and genes associated with the cell cycle and cell proliferation were downregulated in aneuploid cells. Within species, different aneuploidies induced similar changes in gene expression, independent of the specific chromosomal aberrations. Taken together, our results demonstrate that aneuploidies of different chromosomes and in different organisms impact similar cellular pathways and cause a stereotypical antiproliferative response that must be overcome before transformation.

    The adverse health consequences of the Iraq War (2003-11) were profound. We conclude that at least 116,903 Iraqi non-combatants and more than 4800 coalition military personnel died over the 8-year course. Many Iraqi civilians were injured or became ill because of damage to the health-supporting infrastructure of the country, and about 5 million were displaced. More than 31,000 US military personnel were injured and a substantial percentage of those deployed suffered post-traumatic stress disorder, traumatic brain injury, and other neuropsychological disorders and their concomitant psychosocial problems. Many family members of military personnel had psychological problems. Further review of the adverse health consequences of this war could help to minimise the adverse health consequences of, and help to prevent, future wars.

    In spite of a growing awareness of the future consequences of rising petroleum imports, oil shale has not become an integral element of federal energy policy. This paper discusses how recent actions by the private sector and regional governments have begun to reverse opinions. First, published estimates by industry have refuted the notion that shale oil will cost $60 to $80 per barrel. Second, state and local governments in the West are supporting planned development. In the early 1980's, there was extreme resistance to the mammoth development proposed at the time. Jobs and economic development are now very important. Third environmental regulations have been adopted which give the private sector and government a better framework from which to interact.

    This article focuses on the relevance that the dimension of the future has for promoting healthy and active aging. Older people generally have difficulties in talking about the future and when they do they generally express very negative perspectives on it. The data analyzed in this paper are part of an on-going interdisciplinary research project: "Aging, poverty and social exclusion: an interdisciplinary study on innovative support services" (https://apseclunl.wordpress.com/). The project aims at documenting good practices in social intervention with older people who are at risk of exclusion. This study describes and critically discusses an activity carried out in Portugal among older women in a poor area in the suburb of Lisbon entitled "self-awareness workshop on the future". Through a detailed discourse analysis within an ethnomethodological framework the study shows age membership categorizations in use and categorization processes, examining the workshop interaction. In particular, the article describes how the psychologist works at deconstructing and problematizing the negative connotations related to age membership categories. Taking into consideration the interactionally constructed nature of aging and the material consequences that different attitudes towards aging can imply is very important in particular in relation to the provision of services to older people.

  11. Stakeholder position paper: dairy producer.

    Bacterial antimicrobial resistance is a problem common to both animal and public health. An important public policy issue is to develop and implement prudent use practices where antimicrobials are used. As policy develops, there are questions regarding the use of antimicrobials in animal agriculture and whether these uses constitute prudent use. A series of papers assessing the risk to the public health from agricultural use of antimicrobials have consistently concluded that risk estimation is hampered by the lack of data that describe the amount, types, and uses of antimicrobials in animal agriculture. The absence of information has spurred efforts to develop a framework to collect these data. However, the reasons and benefit of collecting these data should be carefully defined. The dairy industry, contrasted to other major animal commodities, is not focused on meat production but on milk production. Milk production is constrained by disease and antimicrobial treatment is a common management tool, but unlike many other animal agricultural systems where the value and safety of the product is measured in the future; the value of milk is zero when an antimicrobial is used in a lactating cow and milk must be discarded because of residues. While there are exceptions, e.g. non-lactating cow therapy, this difference results in antimicrobials being used sporadically and directed at therapy rather than prophylactic uses. In the dairy industry, antimicrobial use data and its consequences may exist in sufficient detail or could be estimated from existing datasets without the expense of additional surveys. Finally, the main food product milk is mainly pasteurized and all shipments of milk from the farm to the processing plant are tested for the presence of antimicrobials. This makes the likelihood of farm-origin antimicrobials or bacteria appearing in finished product very low. This suggests that the use and quantity of antimicrobials in the dairy system has little impact on

    Auditory neuropathy/dys-synchrony is a form of hearing impairment in which cochlear outer hair cell function is spared but neural transmission in the auditory pathway is disordered. This condition, or group of conditions with a common physiologic profile, accounts for approximately 7% of permanent childhood hearing loss and a significant (but as yet undetermined) proportion of adult impairment. This paper presents an overview of the mechanisms underlying auditory neuropathy/dys-synchrony-type hearing loss and the clinical profile for affected patients. In particular it examines the perceptual consequences of auditory neuropathy/dys-synchrony, which are quite different from those associated with sensorineural hearing loss, and considers currently available, and future management options.

    Although studies have examined clinical characteristics of kleptomania, no previous studies have examined the legal consequences of kleptomania. From 2001 to 2007, 101 adult subjects (n = 27 [26.7%] males) with DSM-IV kleptomania were assessed on sociodemographics and clinical characteristics including symptom severity, comorbidity, and legal repercussions. Of 101 subjects with kleptomania, 73.3% were female. Mean age of shoplifting onset was 19.4 +/- 12.0 years, and subjects shoplifted a mean of 8.2 +/- 11.0 years prior to meeting full criteria for kleptomania. Co-occurring depressive, substance use, and impulse control disorders were common. Sixty-nine subjects with kleptomania (68.3%) had been arrested, 36.6% had been arrested but not convicted, 20.8% had been convicted and incarcerated after conviction, while only 10.9% had been convicted and not incarcerated after conviction. Kleptomania is associated with significant legal repercussions. The findings emphasize the need for rigorous treatment approaches to target kleptomania symptoms and prevent re-offending.

    The primary purpose of this model report is to develop abstractions for the response of engineered barrier system (EBS) components to seismic hazards at a geologic repository at Yucca Mountain, Nevada, and to define the methodology for using these abstractions in a seismic scenario class for the Total System Performance Assessment - License Application (TSPA-LA). A secondary purpose of this model report is to provide information for criticality studies related to seismic hazards. The seismic hazards addressed herein are vibratory ground motion, fault displacement, and rockfall due to ground motion. The EBS components are the drip shield, the waste package, and the fuel cladding. The requirements for development of the abstractions and the associated algorithms for the seismic scenario class are defined in ''Technical Work Plan For: Regulatory Integration Modeling of Drift Degradation, Waste Package and Drip Shield Vibratory Motion and Seismic Consequences'' (BSC 2004 [DIRS 171520]). The development of these abstractions will provide a more complete representation of flow into and transport from the EBS under disruptive events. The results from this development will also address portions of integrated subissue ENG2, Mechanical Disruption of Engineered Barriers, including the acceptance criteria for this subissue defined in Section 2.2.1.3.2.3 of the ''Yucca Mountain Review Plan, Final Report'' (NRC 2003 [DIRS 163274]).

    2014-05-01

    Resistance to anticoagulant rodenticides, such as warfarin was first described in 1958. Polymorphisms in the vitamin K epoxide reductase complex subunit 1 (VKORC1) gene and respective substitutions of amino acids in the VKOR enzyme are the major cause for rodenticide resistance. Resistant Norway rats in Germany are characterized by the Tyr139Cys genotype, which is spread throughout the northwest of the country. Resistant house mice with the VKOR variants Tyr139Cys, Leu128Ser and Arg12Trp/Ala26Ser/Ala48Thr/Arg61Leu (spretus type) are distributed over a number of locations in Germany. Resistance can reduce management attempts with consequences for stored product protection, hygiene and animal health. Anticoagulants of the first generation (warfarin, chlorophacinone, coumatetralyl) as well as bromadiolone and difenacoum are not an option for the control of resistant Norway rats. The same applies for house mice whereby the tolerance to compounds can be different between local incidences. Due to the higher toxicity and tendency to persist, the most potent anticoagulant rodenticides brodifacoum, flocoumafen and difethialone should be applied but only where resistance is known. In other cases less toxic anticoagulants should be preferred for rodent management in order to mitigate environmental risks. Resistance effects of further VKOR polymorphisms and their combinations, the spread of resistant rats and conditions supporting and reducing resistance should be investigated in order to improve resistance management strategies.

    Aims This paper examines (1) gender and country differences in negative consequences related to drinking; (2) relative rates of different consequences; (3) country-level predictors of consequences. Design, setting and participants Multi-level analyses used survey data from the GENACIS collaboration. Measurements Measures included 17 negative consequences grouped into (a) high endorsement acute, (b) personal and (c) social. Country-level measures included average frequency and quantity of drinking, percent current drinkers, Gross Domestic Product (GDP) and Human Development Index (HDI). Findings Overall, the three groupings of consequences were reported by 44%, 12% and 7% of men and by 31%, 6% and 3% of women, respectively. More men than women endorsed all consequences but gender differences were greatest for consequences associated with chronic drinking and social consequences related to male roles. The highest prevalence of consequences was in Uganda, lowest in Uruguay. Personal and social consequences were more likely in countries with higher usual quantity, fewer current drinkers, and lower scores on GDP and HDI. However, significant interactions with individual-level quantity indicated a stronger relationship between consequences and usual quantity among drinkers in countries with lower quantity, more current drinkers and higher scores on GDP and HDI. Conclusions Both gender and country need to be taken into consideration when assessing adverse drinking consequences. Individual measures of alcohol consumption and country-level variables are associated with experiencing such consequences. Additionally, country-level variables affect the strength of the relationship between usual quantity consumed by individuals and adverse consequences. PMID:21395893

    Relapse after a first episode of schizophrenia is the recurrence of acute symptoms after a period of partial or complete remission. Due to its variable aspects, there is no operational definition of relapse able to modelise the outcome of schizophrenia and measure how the treatment modifies the disease. Follow-up studies based on proxys such as hospital admission revealed that 7 of 10 patients relapsed after a first episode of schizophrenia. The effectiveness of antipsychotic medications on relapse prevention has been widely demonstrated. Recent studies claim for the advantages of atypical over first generation antipsychotic medication. Non-adherence to antipsychotic represents with addictions the main causes of relapse long before some non-consensual factors such as premorbid functioning, duration of untreated psychosis and associated personality disorders. The consequences of relapse are multiple, psychological, biological and social. Pharmaco-clinical studies have demonstrated that the treatment response decreases with each relapse. Relapse, even the first one, will contribute to worsen the outcome of the disease and reduce the capacity in general functionning. Accepting the idea of continuing treatment is a complex decision in which the psychiatrist plays a central role besides patients and their families. The development of integrated actions on modifiable risk factors such as psychosocial support, addictive comorbidities, access to care and the therapeutic alliance should be promoted. Relapse prevention is a major goal of the treatment of first-episode schizophrenia. It is based on adherence to the maintenance treatment, identification of prodromes, family active information and patient therapeutical education. Copyright © 2013 L’Encéphale.

  10. College students' evaluations of alcohol consequences as positive and negative.

    PubMed

    2011-12-01

    Alcohol expectancy, motivation, and consequences measures assume a known valence of 'positive' and 'negative' outcomes. However, different individuals may rate the same consequences of alcohol use as good or bad. The current study examines the extent to which: (a) college students rate researcher-defined positive consequences as good and researcher-defined negative consequences as bad, and (b) these evaluations predict alcohol use and problems after controlling for previous use. In longitudinal self-reports via web-surveys across the first three semesters of college, students (N=600; 54% women) reported their alcohol use and problems, experienced consequences, and evaluations of those consequences. Contrary to the generally-accepted valence of positive consequences, Fun/Social consequences were viewed as neutral or negative by 22% (having more fun) to 73% (relieving boredom) of participants. Over half of participants evaluated each of the Relaxation, Sex, and Image consequences items as neutral or negative. Consistent with the generally-accepted valence of negative consequences, Physical/Behavioral consequences were viewed by the majority as negative, although 11% (getting in trouble with police/authorities) to 34% (doing/saying something embarrassing) of students rated these consequences as neutral or positive. Independent of levels of previous drinking, more positive evaluations of Fun/Social consequences prospectively predicted frequency, quantity, and maximum drinks. Less negative evaluations of Physical/Behavioral consequences predicted more alcohol problems. There is variation in the evaluations of consequences among college students, and understanding characteristics of those who view consequences as positive or negative may have implications for future alcohol-related behaviors and problems.

    The analysis and identification of risks often result in design changes or modification of operational steps. This paper identifies the potential of unintended consequences as an over-looked result of these changes. Examples of societal changes such as prohibition, regulatory changes including mandating lifeboats on passenger ships, and engineering proposals or design changes to automobiles and spaceflight hardware are used to demonstrate that the System Safety Engineer must be cognizant of the potential for unintended consequences as a result of an analysis. Conclusions of the report indicate the need for additional foresight and consideration of the potential effects of analysis-driven design, processing changes, and/or operational modifications.

    To summarize recent research on unintended consequences associated with implementation and use of health information technology (health IT). Included in the review are original empirical investigations published in English between 2014 and 2015 that reported unintended effects introduced by adoption of digital interventions. Our analysis focuses on the trends of this steam of research, areas in which unintended consequences have continued to be reported, and common themes that emerge from the findings of these studies. Most of the papers reviewed were retrieved by searching three literature databases: MEDLINE, Embase, and CINAHL. Two rounds of searches were performed: the first round used more restrictive search terms specific to unintended consequences; the second round lifted the restrictions to include more generic health IT evaluation studies. Each paper was independently screened by at least two authors; differences were resolved through consensus development. The literature search identified 1,538 papers that were potentially relevant; 34 were deemed meeting our inclusion criteria after screening. Studies described in these 34 papers took place in a wide variety of care areas from emergency departments to ophthalmology clinics. Some papers reflected several previously unreported unintended consequences, such as staff attrition and patients' withholding of information due to privacy and security concerns. A majority of these studies (71%) were quantitative investigations based on analysis of objectively recorded data. Several of them employed longitudinal or time series designs to distinguish between unintended consequences that had only transient impact, versus those that had persisting impact. Most of these unintended consequences resulted in adverse outcomes, even though instances of beneficial impact were also noted. While care areas covered were heterogeneous, over half of the studies were conducted at academic medical centers or teaching hospitals

  13. Economic Consequences Of Climate Change

    Even though the climate conflict resulting from green houses gases (GHG) emissions was evident by the Nineties and the well-known agreements made, their enforcement is more difficult than that of other environmental agreements. That is because measures to reduce GHG emissions interfere with the heart of the economy and the market: energy (in a broader sense than the energy sector as defined by statistics) and economical growth. Analyzing the environmental policy responses to climate change the conclusion is that GHG emission reduction can only be achieved through intensive environmental policy. While extensive environmental protection complements production horizontally, intensive environmental protection integrates into production and the environment vertically. The latter eliminates the source of the pollution, preventing damage. It utilizes the biochemical processes and self-purification of the natural environment as well as technical development which not only aims to produce state-of-the-art goods, but to make production more environmentally friendly, securing a desired environmental state. While in extensive environmental protection the intervention comes from the outside for creating environmental balance, in intensive environmental protection the system recreates this balance itself. Instead of dealing with the consequences and the polluter pays principle, the emphasis is on prevention. It is important to emphasize that climate strategy decisions have complex effects regarding the aspects of sustainability (economical, social, ecological). Therefore, all decisions are political. At present, and in the near future, market economy decisions have little to do with sustainability values under normal circumstances. Taking social and ecological interests into consideration can only be successful through strategic political aims.

    2016-01-01

    Multi-disciplinary research has supported a relationship between adolescent future orientation (the ability to set future goals and plans) and positive adolescent health and development outcomes. Many preventive strategies—for example contracepting, exercising—are based on taking actions in the present to avoid unwanted or negative future consequences. However, research has been hampered by unclear and often divergent conceptualizations of the future orientation construct. The present paper aims to integrate previous conceptual and operational definitions into a conceptual framework that can inform programs and services for youth and efforts to evaluate future orientation as a target for intervention. Recommendations focus on furthering the study of the construct through measurement synthesis as well as studies of the normative development of future orientation. Also suggested is the need to pair environmental intervention strategies with individual level efforts to improve future orientation in order to maximize benefits. PMID:24523304

    Many organizations face high consequence safety situations where unwanted stimuli due to accidents, catastrophes, or inadvertent human actions can cause disasters. In order to improve interaction among such organizations and to build on each others` experience, preventive approaches, and assessment techniques, the High Consequence Operations Safety Symposium was held July 12--14, 1994 at Sandia National Laboratories, Albuquerque, New Mexico. The symposium was conceived by Dick Schwoebel, Director of the SNL Surety Assessment Center. Stan Spray, Manager of the SNL System Studies Department, planned strategy and made many of the decisions necessary to bring the concept to fruition on a short time scale. Angela Campos and about 60 people worked on the nearly limitless implementation and administrative details. The initial symposium (future symposia are planned) was structured around 21 plenary presentations in five methodology-oriented sessions, along with a welcome address, a keynote address, and a banquet address. Poster papers addressing the individual session themes were available before and after the plenary sessions and during breaks.

    Many results have been obtained when studying scientific papers citations databases in a network perspective. Articles can be ranked according to their current in-degree and their future popularity or citation counts can even be predicted. The dynamical properties of such networks and the observation of the time evolution of their nodes started more recently. This work adopts an evolutionary perspective and proposes an original algorithm for the construction of genealogical trees of scientific papers on the basis of their citation count evolution in time. The fitness of a paper now amounts to its in-degree growing trend and a "dying" paper will suddenly see this trend declining in time. It will give birth and be taken over by some of its most prevalent citing "offspring". Practically, this might be used to trace the successive published milestones of a research field.

    review various aspects of Turbulent Mixing that were discussed at the Second International Conference and Advanced School 'Turbulent Mixing and Beyond', TMB-2009, held in summer 2009 at the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy. The papers are arranged by TMB themes and within each theme they are ordered alphabetically by the last name of the first author, with tutorials following research contributions. Canonical turbulence and turbulent mixing. The theme of canonical turbulence and turbulent mixing is considered by several authors. Casciola et al investigate the dynamics of inertial particles dispersed in a turbulent jet and compare their numerical modeling results with the classical similarity theory of the jet far-field. Remarkable agreement is found between the theory and the direct numerical simulations (DNS), including decay of Stokes numbers with the distance from the origin, self-similarity of the mean axial particle velocity profile, etc. Nagata considers complex turbulent flows, which are known to exhibit no linear critical point for the laminar states, and which are linearly stable at finite Reynolds numbers. Square duct flow and sliding Couette flow in an annulus are considered and nonlinear traveling-wave states are found for the flows with the use of the homotopy approach developed by the author. These states may constitute a skeleton around which a time-dependent trajectory in the phase space is organized. Teitelbaum and Mininni study a decaying 3D incompressible turbulence, which mimicks turbulent mixing in geophysical flows, with rotation rendering the flow anisotropic at large scales. The authors analyze three DNS results (without and with rotation, and with helicity), observe a decoupling of the modes normal to the rotation axis, and show that the helicity decreases the decay rate of turbulence. Wang and Peters investigate the structure of turbulence by studying strain rates of various scalars, including a

    Torture is a strategic means of limiting, controlling, and repressing basic human rights of individuals and communities that is often covert and denied by authorities. Deliberate infliction of pain and suffering or intimidation or coercion on children to obtain a confession or information, for punishment of real or perceived offences on the basis of discrimination about race, ethnic or political affiliation, is practiced in many places around the world. Impact of torture on children may vary depending on the child's coping strategies, cultural and social circumstances. We at Refugee Therapy Centre provide psychotherapy and associated treatments to people who have been tortured, giving priority to children. While our main objective is provision of clinical services, our focus is also to influence policy and practice by searching for evidence and demonstrating solutions to improve the lives, homes and communities of children disadvantaged by torture and the services that support them. We seek to provide some remedies to children of refugees who are suffering the consequence of trauma that they experienced and demonstrate good practice. In this paper I will give a brief introduction of our work at the RTC. I then discuss and reflect on children and torture. I will present a vignette and some examples of clinical intervention.

    2009-01-01

    Over the next quarter century in North America, the following eventualities are likely for physiology and endocrinology research with agricultural animals. 1) Total funding adjusted for inflation will change little but will come less from public sources, and most of that will be in the context of human health. Much of the privately funded research will be herd specific and remain proprietary. 2) The numbers of MS, PhD, and postdoctoral students probably will decrease, but research in the context of credentialing will remain important. 3) Resources such as expanded databases in genomics and proteomics, and remarkable new tools such as small inhibitory RNA will continue to become available, likely at a faster rate than in the previous 25 yr. 4) The huge amounts of data from production agriculture will make agricultural animals ideal models for some kinds of basic research, such as studying fetal programming, resulting in synergy with more applied research. Most of these experimental animals will be in private production herds and flocks, even when work is publicly funded. 5) The trend toward more interdisciplinary research will continue, especially considering interactions among reproduction, health, nutrition, selective breeding, management factors, and societal concerns; reductionist research probing deeper into cellular and molecular mechanisms will remain important, as will whole-animal approaches. 6) Agricultural animals are a product of evolution plus selective breeding. Insights drawn from the former will aid progress in the latter. One focus of research in physiology and endocrinology will be understanding heterosis, inbreeding depression, and epigenetic effects as it becomes possible to manipulate and identify the allelic structure of individual animals. 7) Additional insightful concepts will evolve that will simplify thinking in some respects, such as the maternal to embryonic shift in transcribed RNA in early embryos; however, animal biology will turn out to be even more complex than most of us currently imagine.

  8. Adverse consequences of immunostimulation.

    Ponce, Rafael

    2008-01-01

    The therapeutic uses of immunostimulatory agents are generally in the treatments of infections or cancer. The traditional example of vaccination is one form of immunostimulation used in the prevention of pathogenic infections or cancer (e.g., human papillomavirus vaccine). Recombinant cytokines are increasingly used to stimulate immune system function. For example, interferon-alpha (IFNalpha) and interleukin (IL)-2 have been used to treat chronic hepatitis C virus infection and metastatic melanoma, respectively. In contrast, monoclonal antibodies are used to target malignant cells for elimination via antibody-dependent cytotoxicity mechanisms or apoptosis, including the anti-CD20 monoclonal antibody rituximab and the anti-CD56 monoclonal antibody alemtuzumab used in the treatment of B-cell malignancies, and the anti-erb2 receptor antibody trastuzumab used in the treatment of breast cancer. Finally, immunostimulation may develop via modulation of pathways involved in immune system regulation. For example, the anti-CD28 monoclonal antibody TGN1412 was developed as an agonist of regulatory T-cells for treatment of T-cell-mediated chronic inflammatory diseases or leukemias. A panel was convened to discuss potential toxicities associated with immunostimulation. At the Immunotoxicology IV meeting in 2006, a panel, moderated by Dr. Robert House (Dynport Vaccine Co., Frederick, MD), included Drs. Gary Burleson (Burleson Research Technologies, Inc., Raleigh, NC), Kenneth Hastings (US FDA, Center for Drug Evaluation and Research [CDER], Rockville, MD), Barbara Mounho (Amgen, Thousand Oaks, CA), Rafael Ponce (ZymoGenetics, Inc., Seattle, WA), Mark Wing (Huntington Life Sciences, Cambridgeshire, United Kingdom), Lauren Black (Navigators Consulting, Sparks, NV) and Anne Pilaro (US FDA, CDER, Rockville, MD).

    In the European Region, floods are the most common natural disaster, causing extensive damage and disruption. In Italy, it has been estimated that over 68% of municipalities are at high hydrogeological risk and with the recent intense rainfall events local populations have been facing severe disruptions. The health consequences of floods are wide ranging and are dependent upon the vulnerability of the environment and the local population. Health effects can be a direct or indirect consequence of flooding. The immediate health impacts of floods include drowning, heart attacks, injuries and hypothermia. The indirect effects include, injuries and infections, water-borne infectious disease, mental health problems, respiratory disease and allergies in both the medium and long term after a flood. Future efforts should be addressed to integrate health preparedness and prevention measures into emergency flood plans and hydrological warning systems.

    2012-01-01

    Vascular calcification has severe clinical consequences and is considered an accurate predictor of future adverse cardiovascular events, including myocardial infarction and stroke. Previously vascular calcification was thought to be a passive process which involved the deposition of calcium and phosphate in arteries and cardiac valves. However, recent studies have shown that vascular calcification is a highly regulated, cell-mediated process similar to bone formation. In this article, we outline the current understanding of key mechanisms governing vascular calcification and highlight the clinical consequences. By understanding better the molecular pathways and genetic circuitry responsible for the pathological mineralization process novel drug targets may be identified and exploited to combat and reduce the detrimental effects of vascular calcification on human health.

    2012-01-01

    Phytoestrogens, estrogenic compounds derived from plants, are ubiquitous in human and animal diets. These chemicals are generally much less potent than estradiol but act via similar mechanisms. The most common source of phytoestrogen exposure to humans is soybean-derived foods that are rich in the isoflavones genistein and daidzein. These isoflavones are also found at relatively high levels in soy-based infant formulas. Phytoestrogens have been promoted as healthy alternatives to synthetic estrogens and are found in many dietary supplements. The aim of this review is to examine the evidence that phytoestrogen exposure, particularly in developmentally sensitive periods of life, has consequences for future reproductive health.

  8. Biosensing with Paper-Based Miniaturized Printed Electrodes-A Modern Trend.

    Silveira, Célia M; Monteiro, Tiago; Almeida, Maria Gabriela

    2016-09-28

    From the bench-mark work on microfluidics from the Whitesides's group in 2007, paper technology has experienced significant growth, particularly regarding applications in biomedical research and clinical diagnostics. Besides the structural properties supporting microfluidics, other advantageous features of paper materials, including their versatility, disposability and low cost, show off the great potential for the development of advanced and eco-friendly analytical tools. Consequently, paper was quickly employed in the field of electrochemical sensors, being an ideal material for producing custom, tailored and miniaturized devices. Stencil-, inkjet-, or screen-printing are the preferential techniques for electrode manufacturing. Not surprisingly, we witnessed a rapid increase in the number of publications on paper based screen-printed sensors at the turn of the past decade. Among the sensing strategies, various biosensors, coupling electrochemical detectors with biomolecules, have been proposed. This work provides a critical review and a discussion on the future progress of paper technology in the context of miniaturized printed electrochemical biosensors.

  9. Consequence Prioritization Process for Potential High Consequence Events (HCE)

    SciTech Connect

    Freeman, Sarah G.

    2016-10-31

    This document describes the process for Consequence Prioritization, the first phase of the Consequence-Driven Cyber-Informed Engineering (CCE) framework. The primary goal of Consequence Prioritization is to identify potential disruptive events that would significantly inhibit an organization’s ability to provide the critical services and functions deemed fundamental to their business mission. These disruptive events, defined as High Consequence Events (HCE), include both events that have occurred or could be realized through an attack of critical infrastructure owner assets. While other efforts have been initiated to identify and mitigate disruptive events at the national security level, such as Presidential Policy Directive 41 (PPD-41), this process is intended to be used by individual organizations to evaluate events that fall below the threshold for a national security. Described another way, Consequence Prioritization considers threats greater than those addressable by standard cyber-hygiene and includes the consideration of events that go beyond a traditional continuity of operations (COOP) perspective. Finally, Consequence Prioritization is most successful when organizations adopt a multi-disciplinary approach, engaging both cyber security and engineering expertise, as in-depth engineering perspectives are required to recognize and characterize and mitigate HCEs. Figure 1 provides a high-level overview of the prioritization process.

  10. Gas Mitigation in Paper Production

    2017-07-01

    The Brazilian paper industry has competitive advantages offered by the favorable climate, which favors an increase in the yield of forest restoration, and consequently, in the productive process. On the other hand, following the greenhouse gases (GHG), we can see our constantly changing sun, causing the solar storms, allowing their prevention or mitigating measures. The objective of this work is to contribute to the construction of the understanding necessary for the reduction of GHG emission from a preliminary analysis of the pulp and paper sector. As a secondary objective, the text preliminarily analyzes a company’s behavior against the backdrop of the Paris Accord, which strengthens the global response to the threat of climate change and strengthens the capacity of countries to deal with the impacts of such changes. The identification of best practices in the pulp and paper industry is understood, focusing on environmental sustainability, such as the adoption of reforestation, obtaining significant results. In the case of the paper industry, the management of public forests for sustainable production, within the structure of the Ministry of the Environment, establishes the promotion of public awareness about the importance of conservation, recovery and sustainable management of forest resources.

    Cannabis can have negative effects in its users, and a range of acute and chronic health problems associated with cannabis use has been dentified. Acute cannabis consumption is rarely lethal but it is associated with an increased risk of motor vehicle accident because of longer reaction time or impaired motor coordination. Chronic effects of cannabis use include generally cardiovascular and respiratory consequences but there are also oral, gastrointestinal, cutaneous and mucous, metabolic, gynecologic and obstetrical, sexual consequences, and cancer But associated tobacco smoking or other potential confounders may explain part of those somatic consequences.

  12. The physics of paper

    Paper is a material known to everybody. It has a network structure consisting of wood fibres that can be mimicked by cooking a portion of spaghetti and pouring it on a plate, to form a planar assembly of fibres that lie roughly horizontal. Real paper also contains other constituents added for technical purposes. This review has two main lines of thought. First, in the introductory part, we consider the physics that one encounters when 'using' paper, an everyday material that exhibits the presence of disorder. Questions arise, for instance, as to why some papers are opaque and others translucent, some are sturdy and others sloppy, some readily absorb drops of liquid while others resist the penetration of water. The mechanical and rheological properties of paper and paperboard are also interesting. They are inherently dependent on moisture content. In humid conditions paper is ductile and soft, in dry conditions brittle and hard. In the second part we explain in more detail research problems concerned with paper. We start with paper structure. Paper is made by dewatering a suspension of fibres starting from very low content of solids. The processes of aggregation, sedimentation and clustering are familiar from statistical mechanics. Statistical growth models or packing models can simulate paper formation well and teach a lot about its structure. The second research area that we consider is the elastic and viscoelastic properties and fracture of paper and paperboard. This has traditionally been the strongest area of paper physics. There are many similarities to, but also important differences from, composite materials. Paper has proved to be convenient test material for new theories in statistical fracture mechanics. Polymer physics and memory effects are encountered when studying creep and stress relaxation in paper. Water is a 'softener' of paper. In humid conditions, the creep rate of paper is much higher than in dry conditions. The third among our topics is the

  14. The Educational Consequences of Teen Childbearing

    2013-01-01

    A huge literature shows that teen mothers face a variety of detriments across the life course, including truncated educational attainment. To what extent is this association causal? The estimated effects of teen motherhood on schooling vary widely, ranging from no discernible difference to 2.6 fewer years among teen mothers. The magnitude of educational consequences is therefore uncertain, despite voluminous policy and prevention efforts that rest on the assumption of a negative and presumably causal effect. This study adjudicates between two potential sources of inconsistency in the literature—methodological differences or cohort differences—by using a single, high-quality data source: namely, The National Longitudinal Study of Adolescent Health. We replicate analyses across four different statistical strategies: ordinary least squares regression; propensity score matching; and parametric and semiparametric maximum likelihood estimation. Results demonstrate educational consequences of teen childbearing, with estimated effects between 0.7 and 1.9 fewer years of schooling among teen mothers. We select our preferred estimate (0.7), derived from semiparametric maximum likelihood estimation, on the basis of weighing the strengths and limitations of each approach. Based on the range of estimated effects observed in our study, we speculate that variable statistical methods are the likely source of inconsistency in the past. We conclude by discussing implications for future research and policy, and recommend that future studies employ a similar multimethod approach to evaluate findings. PMID:24078155

  16. Positive consequences of SETI before detection

    NASA Astrophysics Data System (ADS)

    Tough, A.

    Even before a signal is detected, six positive consequences will result from the scientific search for extraterrestrial intelligence, usually called SETI. (1) Humanity's self-image: SETI has enlarged our view of ourselves and enhanced our sense of meaning. Increasingly, we feel a kinship with the civilizations whose signals we are trying to detect. (2) A fresh perspective: SETI forces us to think about how extraterrestrials might perceive us. This gives us a fresh perspective on our society's values, priorities, laws and foibles. (3) Questions: SETI is stimulating thought and discussion about several fundamental questions. (4) Education: some broad-gage educational programs have already been centered around SETI. (5) Tangible spin-offs: in addition to providing jobs for some people, SETI provides various spin-offs, such as search methods, computer software, data, and international scientific cooperation. (6) Future scenarios: SETI will increasingly stimulate us to think carefully about possible detection scenarios and their consequences, about our reply, and generally about the role of extraterrestrial communication in our long-term future. Such thinking leads, in turn, to fresh perspectives on the SETI enterprise itself.

  17. Human factors in high consequence manufacturing systems

    SciTech Connect

    Forsythe, C.; Grose, E.

    1997-11-01

    A high consequence system is often defined as one in which the potential exists for severe or catastrophic accidents. Familiar examples include nuclear power plants, airline and other mass transportation, dams and reservoirs, and large-scale food processing. Many manufacturing systems also qualify as high consequence systems. Much of the authors` experience with high consequence systems derives from work associated with the surveillance and dismantlement of nuclear weapons for the US Department of Energy. With such operations, there exists a risk of high explosive detonation accompanied by radiological dispersal and, potentially, nuclear detonation. Analysis of major industrial accidents such as Three Mile Island, Chernobyl and Bhopal have revealed that these incidents were not attributable to a single event or direct cause, but were the result of multiple factors that combined to create a condition ripe for an accident. In each case, human error was a critical factor contributing to the accident. Consequently, many authors have emphasized the need for greater appreciation of systematic factors and in particular, human activities. This paper discusses approaches used in hazard analysis of US nuclear weapons operations to assess risk associated with human factors.

  19. Assessing the consequences of unrealistic optimism: Challenges and recommendations.

    PubMed

    Shepperd, James A; Pogge, Gabrielle; Howell, Jennifer L

    2017-04-01

    Of the hundreds of studies published on unrealistic optimism (i.e., expecting a better personal future than is reasonably likely), most have focused on demonstrating the phenomenon, examining boundary conditions, or documenting causes. Few studies have examined the consequences of unrealistic optimism. In this article, we provide an overview of the measurement of unrealistic optimism, review possible consequences, and identify numerous challenges confronting investigators attempting to understand the consequences. Assessing the consequences of unrealistic optimism is tricky, and ultimately probably impossible when researchers assess unrealistic optimism at the group level (which reveals if a group of people is displaying unrealistic optimism on average) rather than the individual level (which reveals whether a specific individual displays unrealistic optimism). We offer recommendations to researchers who wish to examine the consequences of unrealistic optimism.

    Voss, Clifford I.

    2005-01-01

    “The Future of Hydrogeology” would seem to be an overly ambitious topic for a theme issue of Hydrogeology Journal or for any other journal. Only a modicum of common sense and experience provides the insight that predicting the future of a science is a task fraught with uncertainty that should be approached with caution and humility. Please be assured that the intent of this issue of the journal is not to predict the future but rather to instigate discussion and to inspire creative thinking about hydrogeology. In their articles, authors have presented personal opinions concerning the future evolution of their subjects based on their experience. This is an acceptable approach, considering that any view of the future can be no more than an educated guess. Most authors have given their opinion after an expert and insightful review of the evolution of their subject to the present time or after reviewing the current state of knowledge or practice of their subject. Consequently, this issue of the Hydrogeology Journal provides an exciting view of potential developments in crucial aspects of hydrogeology founded upon developments to date.

    This paper examines (i) gender and country differences in negative consequences related to drinking; (ii) relative rates of different consequences; and (iii) country-level predictors of consequences. Multi-level analyses used survey data from the Gender, Alcohol, and Culture: An International Study (GENACIS) collaboration. Measures included 17 negative consequences grouped into (i) high endorsement acute, (ii) personal and (iii) social. Country-level measures included average frequency and quantity of drinking, percentage who were current drinkers, gross domestic product (GDP) and Human Development Index (HDI). Overall, the three groupings of consequences were reported by 44%, 12% and 7% of men and by 31%, 6% and 3% of women, respectively. More men than women endorsed all consequences, but gender differences were greatest for consequences associated with chronic drinking and social consequences related to male roles. The highest prevalence of consequences was in Uganda and lowest in Uruguay. Personal and social consequences were more likely in countries with higher usual quantity, fewer current drinkers and lower scores on GDP and HDI. However, significant interactions with individual-level quantity indicated a stronger relationship between consequences and usual quantity among drinkers in countries with lower quantity, more current drinkers and higher scores on GDP and HDI. Both gender and country need to be taken into consideration when assessing adverse drinking consequences. Individual measures of alcohol consumption and country-level variables are associated with experiencing such consequences. Additionally, country-level variables affect the strength of the relationship between usual quantity consumed by individuals and adverse consequences. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

  10. A review of the Melcor Accident Consequence Code System (MACCS): Capabilities and applications

    SciTech Connect

    Young, M.

    1995-02-01

    MACCS was developed at Sandia National Laboratories (SNL) under U.S. Nuclear Regulatory Commission (NRC) sponsorship to estimate the offsite consequences of potential severe accidents at nuclear power plants (NPPs). MACCS was publicly released in 1990. MACCS was developed to support the NRC`s probabilistic safety assessment (PSA) efforts. PSA techniques can provide a measure of the risk of reactor operation. PSAs are generally divided into three levels. Level one efforts identify potential plant damage states that lead to core damage and the associated probabilities, level two models damage progression and containment strength for establishing fission-product release categories, and level three efforts evaluate potential off-site consequences of radiological releases and the probabilities associated with the consequences. MACCS was designed as a tool for level three PSA analysis. MACCS performs probabilistic health and economic consequence assessments of hypothetical accidental releases of radioactive material from NPPs. MACCS includes models for atmospheric dispersion and transport, wet and dry deposition, the probabilistic treatment of meteorology, environmental transfer, countermeasure strategies, dosimetry, health effects, and economic impacts. The computer systems MACCS is designed to run on are the 386/486 PC, VAX/VMS, E3M RISC S/6000, Sun SPARC, and Cray UNICOS. This paper provides an overview of MACCS, reviews some of the applications of MACCS, international collaborations which have involved MACCS, current developmental efforts, and future directions.

    Carrilho, Emanuel; Phillips, Scott T; Vella, Sarah J; Martinez, Andres W; Whitesides, George M

    2009-08-01

    This paper describes 96- and 384-microzone plates fabricated in paper as alternatives to conventional multiwell plates fabricated in molded polymers. Paper-based plates are functionally related to plastic well plates, but they offer new capabilities. For example, paper-microzone plates are thin (approximately 180 microm), require small volumes of sample (5 microL per zone), and can be manufactured from inexpensive materials ($0.05 per plate). The paper-based plates are fabricated by patterning sheets of paper, using photolithography, into hydrophilic zones surrounded by hydrophobic polymeric barriers. This photolithography used an inexpensive formulation photoresist that allows rapid (approximately 15 min) prototyping of paper-based plates. These plates are compatible with conventional microplate readers for quantitative absorbance and fluorescence measurements. The limit of detection per zone loaded for fluorescence was 125 fmol for fluorescein isothiocyanate-labeled bovine serum albumin, and this level corresponds to 0.02 the quantity of analyte per well used to achieve comparable signal-to-noise in a 96-well plastic plate (using a solution of 25 nM labeled protein). The limits of detection for absorbance on paper was approximately 50 pmol per zone for both Coomassie Brilliant Blue and Amaranth dyes; these values were 0.4 that required for the plastic plate. Demonstration of quantitative colorimetric correlations using a scanner or camera to image the zones and to measure the intensity of color, makes it possible to conduct assays without a microplate reader.

    Rouchou, Brittany

    2013-05-01

    Infertility affects more than 10% of the world's population. In developing countries, there are severe social, psychological and economic consequences for infertile men and women. All of the cited references are compiled from primary peer-reviewed research articles that were conducted through one-to-one interviews or focus groups in countries of developing regions, such as Africa, Asia and the Middle East. The following paper seeks to raise awareness of the consequences of infertility in developing nations and identify infertility as an under-observed, but significant public health issue. It is proposed that education programmes tailored to each society's specific religious beliefs and grounded traditions must be implemented in order to reverse the social stigma, detrimental psychological effects, and loss of economic security that results from infertility.

  12. Prolactin and schizophrenia: clinical consequences of hyperprolactinaemia.

    PubMed

    Meaney, Anna Maria; O'Keane, Veronica

    2002-07-19

    Prolactin is a polypeptide hormone that is synthesized and secreted from specialised cells of the anterior pituitary gland, known as lactotrophs. The hormone was given it's name because extracts from the bovine pituitary gland caused growth of the crop sac and stimulated the elaboration of crop milk in pigeons, and promoted lactation in rabbits. Although prolactin is best known for the multiple effects it exerts on the mammary gland, it has over 300 separate biological activities not represented by its name. It sub serves multiple roles in reproduction other than lactation and is an important modulator of homeostasis in the mammalian organism. Hence Bern and Nicoll suggested renaming it "omnipotin or versatilin". Schizophrenia is a severe psychiatric disorder that affects approximately one percent of the population worldwide. It is well established that traditional typical anti-psychotics elevate prolactin levels. It is also agreed that the serum prolactin concentration is not elevated in patients with schizophrenia who are not receiving anti-psychotic medication. Hyperprolactinaemia has direct effects on the brain and on other organs. Direct consequences include galactorrhoea. Indirect consequences of hyperprolactinaemia include oligomenorrhoea and amenorrhoea, erratic or absent ovulation, sexual dysfunction, reduced bone mineral density and cardiovascular disease. With the advent of prolactin sparing anti-psychotics, ample consideration needs to be given to the physiological consequences of hyperprolactinaemia in schizophrenic patients. In this paper we will examine molecular biology, secretion and physiology of prolactin. The consequences of hyperprolactinaemia in humans including effects on fertility, sexual dysfunction, bone mineral density, cardiovascular disease, changes in psychopathology and movement disorders will be reviewed. The literature on the association between schizophrenia, anti-psychotic medication and hyperprolactinaemia and more specifically

    1978-01-01

    A study to determine the feasibility of preparing ultrathin papers with a target weight of 3.5 g/m squared from polybenzimidazole (PBI) fibrids was undertaken. Small hand sheets of target weight were fabricated. They were light brown, low density materials with sufficient strength to be readily handleable. Characterization of these sheets included strength, fold endurance, thermal gravimetric analysis in air and nitrogen and photomicrographs. Two different batches of PBI fibrids were studied and differences in fabrication performance were noted. In neither case could target weight papers be prepared using conventional paper making techniques.

  15. Positive consequences of false memories.

    PubMed

    Howe, Mark L; Garner, Sarah R; Patel, Megan

    2013-01-01

    Previous research is replete with examples of the negative consequences of false memories. In the current research, we provide a different perspective on false memories and their development and demonstrate that false memories can have positive consequences. Specifically, we examined the role false memories play in subsequent problem-solving tasks. Children and adults studied and recalled neutral or survival-relevant lists of associated words. They then solved age-normed compound remote associates, some of whose solutions had been primed by false memories created when studying the previous lists. The results showed that regardless of age: (a) survival-related words were not only better recollected but were also more susceptible than neutral words to false memory illusions; and (b) survival-related false memories were better than neutral false memories as primes for problem-solving. These findings are discussed in the context of recent speculation concerning the positive consequences of false memories, and the adaptive nature of reconstructive memory.

    One of the Oak Ridge Y-12 Plant's long range goals is to reduce the amount of waste from the plant. The large amount of waste paper generated by the plant is currently buried in the state permitted landfill. Methods of recycling cardboard and paper which comply with all security requirements, health, safety, and environmental regulations of the Y-12 Plant are sought to conserve the landfill. A process to compact paper into a form which may be used as fuel and fed into the existing steam plant has been developed. A water-resistant briquette has been made from waste paper, a binder, and coal. Laboratory and pilot scale briquetting and pulverizing tests have been completed. These briquettes have physical properties similar to those of coal. 12 tabs.

  3. Consequences of Essential Fatty Acids

    PubMed Central

    Lands, Bill

    2012-01-01

    Essential fatty acids (EFA) are nutrients that form an amazingly large array of bioactive mediators that act on a large family of selective receptors. Nearly every cell and tissue in the human body expresses at least one of these receptors, allowing EFA-based signaling to influence nearly every aspect of human physiology. In this way, the health consequences of specific gene-environment interactions with these nutrients are more extensive than often recognized. The metabolic transformations have similar competitive dynamics for the n-3 and n-6 homologs when converting dietary EFA from the external environment of foods into the highly unsaturated fatty acid (HUFA) esters that accumulate in the internal environment of cells and tissues. In contrast, the formation and action of bioactive mediators during tissue responses to stimuli tend to selectively create more intense consequences for n-6 than n-3 homologs. Both n-3 and n-6 nutrients have beneficial actions, but many common health disorders are undesired consequences of excessive actions of tissue n-6 HUFA which are preventable. This review considers the possibility of preventing imbalances in dietary n-3 and n-6 nutrients with informed voluntary food choices. That action may prevent the unintended consequences that come from eating imbalanced diets which support excessive chronic actions of n-6 mediators that harm human health. The consequences from preventing n-3 and n-6 nutrient imbalances on a nationwide scale may be very large, and they need careful evaluation and implementation to avoid further harmful consequences for the national economy.

    This work describes disposable plasma generators made from metallized paper. The fabricated plasma generators with layered and patterned sheets of paper provide a simple and flexible format for dielectric barrier discharge to create atmospheric plasma without an applied vacuum. The porosity of paper allows gas to permeate its bulk volume and fuel plasma, while plasma-induced forced convection cools the substrate. When electrically driven with oscillating peak-to-peak potentials of ±1 to ±10 kV, the paper-based devices produced both volume and surface plasmas capable of killing microbes. The plasma sanitizers deactivated greater than 99% of Saccharomyces cerevisiae and greater than 99.9% of Escherichia coli cells with 30 s of noncontact treatment. Characterization of plasma generated from the sanitizers revealed a detectable level of UV-C (1.9 nWṡcm-2ṡnm-1), modest surface temperature (60 °C with 60 s of activation), and a high level of ozone (13 ppm with 60 s of activation). These results deliver insights into the mechanisms and suitability of paper-based substrates for active antimicrobial sanitization with scalable, flexible sheets. In addition, this work shows how paper-based generators are conformable to curved surfaces, appropriate for kirigami-like “stretchy” structures, compatible with user interfaces, and suitable for sanitization of microbes aerosolized onto a surface. In general, these disposable plasma generators represent progress toward biodegradable devices based on flexible renewable materials, which may impact the future design of protective garments, skin-like sensors for robots or prosthetics, and user interfaces in contaminated environments.

    2000-07-07

    Behaviour can be a key component of animal population ecology yet the population consequences of behavioural decisions are poorly understood. We conducted a behavioural and demographic study of the bitterling Rhodeus sericeus, a freshwater fish that spawns in live unionid mussels. We used a population model incorporating game theory decisions and measurements of demographic parameters in order to provide predictions of population size among 13 populations of this fish. Our model predicted that the observed behavioural spawning decisions, while maximizing individual fitness, cause a significant 6% reduction in population size compared with randomly distributed spawnings. We discuss our findings in the context of the population consequences of adaptive behaviour.

    In this paper we report the use of a sheet of cellulose fiber-based paper as the dielectric layer used in oxide based semiconductor thin film field-effect transistors (FETs). In this new approach we are using the cellulose fiber-based paper in an "interstrate" structure since the device is build on both sides of the cellulose sheet. Such hybrid FETs present excellent operating characteristics such as high channel saturation mobility (>30 cm2/Vs), drain-source current on/off modulation ratio of approximately 104, near-zero threshold voltage, enhancement n-type operation and sub-threshold gate voltage swing of 0.8 V/decade. The cellulose fiber-based paper FETs characteristics have been measured in air ambient conditions and present good stability. The obtained results outpace those of amorphous Si TFTs and rival with the same oxide based TFTs produced on either glass or crystalline silicon substrates. The compatibility of these devices with large-scale/large-area deposition techniques and low cost substrates as well as their very low operating bias delineates this as a promising approach to attain high-performance disposable electronics like paper displays, smart labels, smart packaging, RFID and point-of-care systems for self analysis in bio-applications, among others.

The bulk of the theory is implicit in Groenewold's and Moyal's seminal papers. But confidence in the autonomy of the formulation accreted slowly and fitfully. As a result, an appraisal of critical milestones cannot avoid subjectivity.

    Osteoporosis is one of the established major consequences of long-duration spaceflights in astronauts seriously undermining their health after their returning on Earth. Indeed, astronauts typically lose more bone mass during one month than postmenopausal women on Earth lose in one year. To date, countermeasures mainly consist in exercise and supplementation while pharmacological treatment as those used in postmenopausal women are not routine. However, it is evident that exercise and supplementation alone are not enough to maintain bone homeostasis. In this paper we describe the current countermeasures for bone loss during long-term spaceflight, review the modern treatment which are successfully employed to prevent osteoporosis on Earth and that could be quickly used also for astronauts and finally focus on the recent cellular and molecular understanding of bone homeostasis which might provide the basis for the development of future targeted therapies.

    2000-09-21

    An International Workshop on Metrology for X-ray and Neutron Optics has been held March 16-17, 2000, at the Advanced Photon Source, Argonne National Laboratory, near Chicago, Illinois (USA). The workshop gathered engineers and scientists from both the U.S. and around the world to evaluate metrology instrumentation and methods used to characterize surface figure and finish for long grazing incidence optics used in beamlines at synchrotrons radiation sources. This two-day workshop was motivated by the rapid evolution in the performance of x-ray and neutron sources along with requirements in optics figure and finish. More specifically, the performance of future light sources, such as free-electron laser (FEL)-based x-ray sources, is being pushed to new limits in term of both brilliance and coherence. As a consequence, tolerances on surface figure and finish of the next generation of optics are expected to become tighter. The timing of the workshop provided an excellent opportunity to study the problem, evaluate the state of the art in metrology instrumentation, and stimulate innovation on future metrology instruments and techniques to be used to characterize these optics. This paper focuses on FEL optics and metrology needs. (A more comprehensive summary of the workshop can be found elsewhere.) The performance and limitations of current metrology instrumentation will be discussed and recommendations from the workshop on future metrology development to meet the FEL challenges will be detailed.

  4. Projecting the risk of future climate shifts

    NASA Astrophysics Data System (ADS)

    Enfield, David B.; Cid-Serrano, Luis

    2006-06-01

    Recent research has shown that decadal-to-multidecadal (D2M) climate variability is associated with environmental changes that have important consequences for human activities, such as public health, water availability, frequency of hurricanes, and so forth. As scientists, how do we convert these relationships into decision support products useful to water managers, insurance actuaries, and others, whose principal interest lies in knowing when future climate regime shifts will likely occur that affect long-horizon decisions? Unfortunately, numerical models are far from being able to make deterministic predictions for future D2M climate shifts. However, the recent development of paleoclimate reconstructions of the Atlantic Multidecadal Oscillation (AMO) (Gray et al., [2004]) and Pacific Decadal Oscillation (PDO); (MacDonald and Case, [2005]) give us a viable alternative: to estimate probability distribution functions from long climate index series that allow us to calculate the probability of future D2M regime shifts. In this paper, we show how probabilistic projections can be developed for a specific climate mode - the AMO as represented by the Gray et al. ([2004]) tree-ring reconstruction. The methods are robust and can be applied to any D2M climate mode for which a sufficiently long index series exists, as well as to the growing body of paleo-proxy reconstructions that have become available. The target index need not be a paleo-proxy calibrated against a climate index; it may profitably be calibrated against a specific resource of interest, such as stream flow or lake levels.

    This paper examines the consequences of the recent economic downturn and UK government spending cuts, as exacerbations of prevailing trends in neoliberal employment policy, on temporal perception, specifically as it relates to the adaptation of subjective anticipations of and projections into the future to objective prospects of unemployment by class. Grounded in a phenomenologically-minded Bourdieusian conceptualization of class and time and contextualized by statistics on chances of job loss, it draws on qualitative research with 57 individuals from across the class structure to chart differing dispositions toward the future. In particular, it distinguishes three orientations - the future as controllable, the future as uncontrollable and the future as reasonably controllable - which appear to correspond with resources possessed. © London School of Economics and Political Science 2013.

  12. Perceptual consequences of disrupted auditory nerve activity.

    PubMed

    Zeng, Fan-Gang; Kong, Ying-Yee; Michalewski, Henry J; Starr, Arnold

    2005-06-01

    Perceptual consequences of disrupted auditory nerve activity were systematically studied in 21 subjects who had been clinically diagnosed with auditory neuropathy (AN), a recently defined disorder characterized by normal outer hair cell function but disrupted auditory nerve function. Neurological and electrophysical evidence suggests that disrupted auditory nerve activity is due to desynchronized or reduced neural activity or both. Psychophysical measures showed that the disrupted neural activity has minimal effects on intensity-related perception, such as loudness discrimination, pitch discrimination at high frequencies, and sound localization using interaural level differences. In contrast, the disrupted neural activity significantly impairs timing related perception, such as pitch discrimination at low frequencies, temporal integration, gap detection, temporal modulation detection, backward and forward masking, signal detection in noise, binaural beats, and sound localization using interaural time differences. These perceptual consequences are the opposite of what is typically observed in cochlear-impaired subjects who have impaired intensity perception but relatively normal temporal processing after taking their impaired intensity perception into account. These differences in perceptual consequences between auditory neuropathy and cochlear damage suggest the use of different neural codes in auditory perception: a suboptimal spike count code for intensity processing, a synchronized spike code for temporal processing, and a duplex code for frequency processing. We also proposed two underlying physiological models based on desynchronized and reduced discharge in the auditory nerve to successfully account for the observed neurological and behavioral data. These methods and measures cannot differentiate between these two AN models, but future studies using electric stimulation of the auditory nerve via a cochlear implant might. These results not only show the unique

  13. Reconsidering Health Consequences of the Chernobyl Accident

    PubMed Central

    2015-01-01

    The Chernobyl accident led to major human suffering caused by the evacuation and other counter-measures. However, the direct health consequences of the accident-related radiation exposures, besides the acute effects and small number of thyroid cancers, have not been observed. This absence is challenged by some influential groups affecting public policies who claim that the true extent of radiogenic health consequences is covered up. We consider such claims. The most conservative (in this case – overestimating) linear no-threshold hypothesis was used to calculate excess cancer expectations for cleanup workers, the population of the contaminated areas and the global population. Statistical estimations were performed to verify whether such expected excess was detectable. The calculated cancer excess for each group is much less than uncertainties in number of cancer cases in epidemiological studies. Therefore the absence of detected radiation carcinogenesis is in full correspondence with the most conservative a priori expectations. Regarding the cover-up claims, rational choice analysis was performed. Such analysis shows that these claims are ill-founded. The present overcautious attitude to radiological hazards should be corrected in order to mitigate the present suffering and to avoid such suffering in the future. PMID:26674769

  14. Stress in obesity: cause or consequence?

    PubMed

    Foss, Brynjar; Dyrstad, Sindre M

    2011-07-01

    Obesity is a global public health challenge that increases the risk of various diseases including type 2 diabetes mellitus, hypertension and cancer, and will in the future cause further increases in the incidence of chronic disease. Understanding the mechanisms of obesity is critical if we are to prevent and treat this pandemic challenge. Diet and physical activity have traditionally been the major tasks in preventing and treating obesity. However, other mechanisms are now also being considered in the quest for knowledge and understanding of obesity, including the body's stress system and cortisol release. While it seems evident that stress is a cause of obesity, whether stress is also a consequence of obesity has up to now only briefly been discussed. The aim of this article is to elucidate how stress and obesity might be linked and discuss the cause/consequence relationship between the stress response and obesity. Our hypothesis is that stress and obesity interfere by positive feedback. This may be an important issue in both our understanding and coping of obesity. Copyright © 2011 Elsevier Ltd.

  15. [Fetal pain - neurobiological causes and consequences].

    PubMed

    Gonçalves, Nuno; Rebelo, Sandra; Tavares, Isaura

    2010-01-01

    The existence of putatively painful situations to the fetus demands a careful evaluation of the issue of fetal pain. Several indirect approaches are used to evaluate the existence of fetal pain. Neurobiological studies showed that from the 30th week on, the anatomical and physiological system for pain transmission is already developed, with the connections from the periphery to the cortex being successively established. Stress responses to a painful stimulation are complex but they can be detected from the 16th week on. There is activation of the hypothalamus-pituitary-adrenal axis, autonomic nervous system and hemodynamic changes in response to nociceptive stimulation. In prematures exposed to pain there are significant increases of adrenaline, noradrenaline and cortisol, hemodynamic changes, motor reflexes and facial reactions. The changes induced by strong nociceptive stimulation of newborns have important postnatal consequences since they affect future reactions to noxious stimuli. Central sensitization and immaturity of the pain inhibitory system are the main neurobiological explanations for the increased pain. Detailed studies of the neurobiological mechanisms of the transmission of painful stimuli along with follow-up studies of the consequences of exposure to pain during the development of the fetus are necessary to fully understand fetal pain.

  16. Causes and consequences of sleepiness among college students.

    PubMed

    Hershner, Shelley D; Chervin, Ronald D

    2014-01-01

    Daytime sleepiness, sleep deprivation, and irregular sleep schedules are highly prevalent among college students, as 50% report daytime sleepiness and 70% attain insufficient sleep. The consequences of sleep deprivation and daytime sleepiness are especially problematic to college students and can result in lower grade point averages, increased risk of academic failure, compromised learning, impaired mood, and increased risk of motor vehicle accidents. This article reviews the current prevalence of sleepiness and sleep deprivation among college students, contributing factors for sleep deprivation, and the role of sleep in learning and memory. The impact of sleep and sleep disorders on academics, grade point average, driving, and mood will be examined. Most importantly, effective and viable interventions to decrease sleepiness and sleep deprivation through sleep education classes, online programs, encouragement of naps, and adjustment of class time will be reviewed. This paper highlights that addressing sleep issues, which are not often considered as a risk factor for depression and academic failure, should be encouraged. Promotion of university and college policies and class schedules that encourage healthy and adequate sleep could have a significant impact on the sleep, learning, and health of college students. Future research to investigate effective and feasible interventions, which disseminate both sleep knowledge and encouragement of healthy sleep habits to college students in a time and cost effective manner, is a priority.

    In the past, human activities often resulted in mercury releases to the biosphere with little consideration of undesirable consequences for the health of humans and wildlife. This paper outlines the pathways through which humans and wildlife are exposed to mercury. Fish consumption is the major route of exposure to methylmercury. Humans can also receive toxic doses of mercury through inhalation of elevated concentrations of gaseous elemental mercury. We propose that any effective strategy for reducing mercury exposures requires an examination of the complete life cycle of mercury. This paper examines the life cycle of mercury from a global perspective and then identifies several approaches to measuring the benefits of reducing mercury exposure, policy options for reducing Hg emissions, possible exposure reduction mechanisms, and issues associated with mercury risk assessment and communication for different populations.

    Major political parties remain publicly committed to Medicare and community-rated voluntary health insurance. It is important to understand the future financial consequences of this policy in order to assist community debate about whether such a commitment is appropriate or some other policy should be developed. This paper describes development of, and results from, the APHA health financing model. It suggests that health expenditure would represent 12.9% of gross domestic product by 2021, compared to 8.5% in 1995. Increasing per capita expenditure is the major contributor to the growth, with demographic changes responsible for only 14.3%.

    The ongoing changes in electric power generation are resulting in new requirements for the classical generating units. In consequence a paradigm change in operation of power systems is necessary and a new approach in finding solutions is needed. The presented paper is dealing with the new requirements on current and future energy systems with the focus on hydro power generation. A power generation landscape for some European regions is shown and generation and operational flexibility is explained. Based on the requirements from the Transmission System Operator in UK, the transient performance of a Pumped Storage installation is discussed.

  1. Measuring Engagement with the Potential Consequences of Climate Change

    Young, N.; Danielson, R. W.; Lombardi, D.

    2015-12-01

    Across three studies, we investigated engagement with the consequences of climate change. We drew from the conceptual change and risk analysis literatures to find the factors that determine how much people will care about future risks. Questions derived from these factors were then asked about many hypothesized consequences of climate change. These consequences were drawn from an Intergovernmental Panel on Climate Change special report (IPCC, 2012) and, in the third study, additionally from the IPCC AR5 (IPCC, 2014). The first two studies, using undergraduate students, demonstrated that some consequences were indeed considerably more engaging than others. The third study used a more representative sample of American adults, drawn from Amazon Mechanical Turk and used the Global Warming's Six Americas Screening Tool (Maibach, Leiserowitz, Roser-Renouf, Mertz, & Akerlof, 2011) in a large screening survey to find 20 participants in each of the six audiences defined by this tool. These participants were then asked about the potential consequences of climate change. Results again showed that some consequences are considered more engaging than others, and also showed the ways in which members of these six audiences perceive the consequences of climate change differently.

    Whistle-blowing provides an avenue for healthcare workers to express their concerns when there is a breach of patients' safety. Most healthcare organizations have policies in place to prevent reprisals on whistle-blowers. Despite these protective measures, whistle-blowing often leads to negative consequences. A search of articles on whistle-blowing was conducted on MEDLINE (PubMed). Articles were included if they described the consequences of whistle-blowing in the following 3 areas: medical, nursing, and research/pharmaceutical research (Fig. 1). The initial search criteria retrieved 1168 articles, 670 of which were identified for full-text review. A total of 82 studies were included in the final set of literature. Negative consequences to whistle-blowers include occupational, legal, financial, socioemotional, and other (e.g., physical health, character assassination) effects. Positive consequences to clinical services include improvements to patient safety and in successes of employment tribunal claims, settlements, and court injunctions. Positive consequences in research include retraction of articles (with fraudulent data) and changes to medical journal publication rules. Consequences of no whistle-blowing include investigations of individuals for not reporting and negative emotions such as guilt. Whistle-blowing is an avenue to improving patient safety in healthcare. The findings from this integrated review will help shape new whistle-blowing policies. Future whistle-blowing policies must minimize negative consequences to whistle-blowers while enhancing levels of patient safety and quality of care rendered.

  3. Positive drinking consequences among hazardous drinking college students.

    Capron, Daniel W; Schmidt, Norman B

    2012-05-01

    Negative drinking consequences in college students have been well studied, but emerging evidence points to a role for positive drinking consequences in predicting alcohol related problems. Positive drinking consequences appear to be distinct from other drinking constructs such as drinking expectancies and drinking motives. However, no work has evaluated the role of positive drinking consequences in hazardous drinking college students, a population at high risk for alcohol related problems. The goal of the current study was to examine the effect of positive drinking consequences on problem drinking and alcohol problem recognition in a hazardous drinking college sample. Participants (N=222) were hazardous drinking undergraduate students completing a battery of self-report measures about alcohol use. Findings indicated that positive drinking consequences predicted problem drinking above and beyond other related constructs including positive drinking motives (i.e. enhancement and social). However, positive drinking consequences did not appear to play a significant role in alcohol problem recognition. Future research directions and implications for interventions with hazardous drinking college students are discussed.

    2012-05-01

    Life time prevalence of stalking is about 12-20%, while females are more often affected than male. Stalking is a statutory offense. However, it is not an assault of victims' law. For the purpose of health consequences for stalking victims, research in following database were conducted: EMBASE, CINAHL, MEDLINE, PsycINFO and Social Science Index. English and German published studies of the years 2002-2010 were included. 17 primary studies and 2 meta-analyses were identified. Direct physiological consequences are relatively rare; however stalking victims report a poorer physiological health status. Almost every second stalking victim shows impairments on his/her psychical well-being. Impairments of social well-being are common, too. As a result, there is still a lot of research, especially in long-term studies, required. Socio-legal reassessment of stalking will probably benefit only a few of the affected people.

(i) The aggregate impacts of foreign workers on the earnings and employment of native workers are quite small, but differ for selected population subgroups and high ethnic density labor markets. (ii) Immigrants who arrived during the 1970s are less skilled than earlier arrivals, and their earnings will remain substantially below those of natives throughout their working lives. (iii) The evidence on immigrants' receipt of public assistance income is inconclusive.

    Svedhem, Håkan; Grinspoon, David

    In spite of all spacecraft that have visited our nearest planetary neighbor a large number of questions remain to be answered. Exploration of Venus is far from completed. In this chapter we summarize the most important questions to be answered, both in the short term, feasible with the technology of today, and those that only can be addressed in the medium to long term, after additional technology development. A large number of missions have been proposed in recent years but since Venus Express (Svedhem etal.2007) and the ill fated Akatsuki (Nakamura etal.2007) none of these have been selected for flight. Short descriptions of these mission proposals, as much as the information is openly available, are given in the following section. The next section deals with future ground based observations and joint space-ground observations. Finally the priorities for future missions, both for the benefit of improving on the theoretical models for atmospheric circulation, as dealt with in this book, and for an improved understanding of the evolution of Venus as a planet and of terrestrial planets in general, are discussed.

  19. Future contraceptives.

    Alexander, N J

    1995-09-01

    This article looks at the improvements that may occur in contraceptives in the near future. While no product currently under study would be ideal (highly effective, safe, readily reversible, free of side effects, coitally independent, counteract the spread of sexually transmitted diseases, and inexpensive), several would come closer than those available today. For men, the condom is the only currently available contraception, and a thinner version has recently been introduced in response to the criticism that condoms reduce sexual pleasure. Methods under study for men include manipulating hormones to halt sperm production by the intramuscular injection of an androgen in combination with a progestin or by blocking the activity of gonadotropin-releasing hormone. In the future, long-acting reversible agents should be available to directly halt sperm production or maturation. In men and women, vaccines should become available that would use antibodies to disrupt reproduction. Additional hormonal options in women should include hormone-releasing vaginal rings, a simplified contraceptive implant delivery system, a hormone-releasing IUD, and a monthly pill. Vaginal chemicals could be used to impede some of the necessary changes that sperm undergo after ejaculation. Spermicides will also be available with the ability to prevent STDs. The order of appearance of these new contraceptives will probably be nonlatex condoms, vaginal rings, and new implants, followed by disease-reducing spermicides, hormone-releasing IUDs, new emergency contraceptives, a three-month injectable for men, biodegradable implants for women, and immunocontraceptives (if they receive the backing of the industry).
