  1. Assumptions and Policy Decisions for Vital Area Identification Analysis

    Energy Technology Data Exchange (ETDEWEB)

    2016-10-15

    U.S. Nuclear Regulatory Commission and IAEA guidance indicate that certain assumptions and policy questions should be addressed to a Vital Area Identification (VAI) process. Korea Hydro and Nuclear Power conducted a VAI based on current Design Basis Threat and engineering judgement to identify APR1400 vital areas. Some of the assumptions were inherited from Probabilistic Safety Assessment (PSA) as a sabotage logic model was based on PSA logic tree and equipment location data. This paper illustrates some important assumptions and policy decisions for APR1400 VAI analysis. Assumptions and policy decisions could be overlooked at the beginning stage of VAI, however they should be carefully reviewed and discussed among engineers, plant operators, and regulators. Through APR1400 VAI process, some of the policy concerns and assumptions for analysis were applied based on document research and expert panel discussions. It was also found that there are more assumptions to define for further studies for other types of nuclear power plants. One of the assumptions is mission time, which was inherited from PSA.

  2. Drug policy in sport: hidden assumptions and inherent contradictions.

    This paper considers the assumptions underpinning the current drugs-in-sport policy arrangements. We examine the assumptions and contradictions inherent in the policy approach, paying particular attention to the evidence that supports different policy arrangements. We find that the current anti-doping policy of the World Anti-Doping Agency (WADA) contains inconsistencies and ambiguities. WADA's policy position is predicated upon four fundamental principles; first, the need for sport to set a good example; secondly, the necessity of ensuring a level playing field; thirdly, the responsibility to protect the health of athletes; and fourthly, the importance of preserving the integrity of sport. A review of the evidence, however, suggests that sport is a problematic institution when it comes to setting a good example for the rest of society. Neither is it clear that sport has an inherent or essential integrity that can only be sustained through regulation. Furthermore, it is doubtful that WADA's anti-doping policy is effective in maintaining a level playing field, or is the best means of protecting the health of athletes. The WADA anti-doping policy is based too heavily on principals of minimising drug use, and gives insufficient weight to the minimisation of drug-related harms. As a result drug-related harms are being poorly managed in sport. We argue that anti-doping policy in sport would benefit from placing greater emphasis on a harm minimisation model.

  3. Comparative Interpretation of Classical and Keynesian Fiscal Policies (Assumptions, Principles and Primary Opinions

    Full Text Available Adam Smith being its founder, in the Classical School, which gives prominence to supply and adopts an approach of unbiased finance, the economy is always in a state of full employment equilibrium. In this system of thought, the main philosophy of which is budget balance, that asserts that there is flexibility between prices and wages and regards public debt as an extraordinary instrument, the interference of the state with the economic and social life is frowned upon. In line with the views of the classical thought, the classical fiscal policy is based on three basic assumptions. These are the "Consumer State Assumption", the assumption accepting that "Public Expenditures are Always Ineffectual" and the assumption concerning the "Impartiality of the Taxes and Expenditure Policies Implemented by the State". On the other hand, the Keynesian School founded by John Maynard Keynes, gives prominence to demand, adopts the approach of functional finance, and asserts that cases of underemployment equilibrium and over-employment equilibrium exist in the economy as well as the full employment equilibrium, that problems cannot be solved through the invisible hand, that prices and wages are strict, the interference of the state is essential and at this point fiscal policies have to be utilized effectively.Keynesian fiscal policy depends on three primary assumptions. These are the assumption of "Filter State", the assumption that "public expenditures are sometimes effective and sometimes ineffective or neutral" and the assumption that "the tax, debt and expenditure policies of the state can never be impartial".

    KAUST Repository

    Buck, Stephen

    2016-11-03

    The King Abdullah University of Science & Technology (KAUST) library is a ‘born digital’ library. The core, and vast majority, of library resources was acquired in electronic form and a smaller print collection, which complemented the wider collection, was acquired contemporaneously. The purpose of this paper is to determine whether, in conjunction with our specific print collections development policy, we need a complementary E-Resources policy. The writing of such a policy utilizes valuable resources (both staff and time) and involves itself with the sometimes vaguely defined and complex concept of collection evaluation. Issues in e-resources are constantly changing and updates will be necessary to reflect this. How, and how often, do we update our E-Resources CDP? While Biblarz (2001) maintains that the main argument for the existence of a print CDP is to prevent the library from being driven by events or by individual enthusiasms and from purchasing a random set of resources, which may not support the mission of the library this paper explores issues in maintaining a joint print and ‘E’ CDP.

    Quasi-experimental designs are gaining popularity in epidemiology and health systems research-in particular for the evaluation of health care practice, programs, and policy-because they allow strong causal inferences without randomized controlled experiments. We describe the concepts underlying five important quasi-experimental designs: Instrumental Variables, Regression Discontinuity, Interrupted Time Series, Fixed Effects, and Difference-in-Differences designs. We illustrate each of the designs with an example from health research. We then describe the assumptions required for each of the designs to ensure valid causal inference and discuss the tests available to examine the assumptions. Copyright © 2017 Elsevier Inc.

  16. Modelling sexual transmission of HIV: testing the assumptions, validating the predictions

    Baggaley, Rebecca F.; Fraser, Christophe

    2010-01-01

    Purpose of review To discuss the role of mathematical models of sexual transmission of HIV: the methods used and their impact. Recent findings We use mathematical modelling of “universal test and treat” as a case study to illustrate wider issues relevant to all modelling of sexual HIV transmission. Summary Mathematical models are used extensively in HIV epidemiology to deduce the logical conclusions arising from one or more sets of assumptions. Simple models lead to broad qualitative understanding, while complex models can encode more realistic assumptions and thus be used for predictive or operational purposes. An overreliance on model analysis where assumptions are untested and input parameters cannot be estimated should be avoided. Simple models providing bold assertions have provided compelling arguments in recent public health policy, but may not adequately reflect the uncertainty inherent in the analysis. PMID:20543600

  17. Business-as-Unusual: Existing policies in energy model baselines

    International Nuclear Information System (INIS)

    Strachan, Neil

    2011-01-01

    Baselines are generally accepted as a key input assumption in long-term energy modelling, but energy models have traditionally been poor on identifying baselines assumptions. Notably, transparency on the current policy content of model baselines is now especially critical as long-term climate mitigation policies have been underway for a number of years. This paper argues that the range of existing energy and emissions policies are an integral part of any long-term baseline, and hence already represent a 'with-policy' baseline, termed here a Business-as-Unusual (BAuU). Crucially, existing energy policies are not a sunk effort; as impacts of existing policy initiatives are targeted at future years, they may be revised through iterative policy making, and their quantitative effectiveness requires ex-post verification. To assess the long-term role of existing policies in energy modelling, currently identified UK policies are explicitly stripped out of the UK MARKAL Elastic Demand (MED) optimisation energy system model, to generate a BAuU (with-policy) and a REF (without policy) baseline. In terms of long-term mitigation costs, policy-baseline assumptions are comparable to another key exogenous modelling assumption - that of global fossil fuel prices. Therefore, best practice in energy modelling would be to have both a no-policy reference baseline, and a current policy reference baseline (BAuU). At a minimum, energy modelling studies should have a transparent assessment of the current policy contained within the baseline. Clearly identifying and comparing policy-baseline assumptions are required for cost effective and objective policy making, otherwise energy models will underestimate the true cost of long-term emissions reductions.

  18. Assessing framing assumptions in quantitative health impact assessments: a housing intervention example.

    Science.gov (United States)

    Mesa-Frias, Marco; Chalabi, Zaid; Foss, Anna M

    2013-09-01

    Health impact assessment (HIA) is often used to determine ex ante the health impact of an environmental policy or an environmental intervention. Underpinning any HIA is the framing assumption, which defines the causal pathways mapping environmental exposures to health outcomes. The sensitivity of the HIA to the framing assumptions is often ignored. A novel method based on fuzzy cognitive map (FCM) is developed to quantify the framing assumptions in the assessment stage of a HIA, and is then applied to a housing intervention (tightening insulation) as a case-study. Framing assumptions of the case-study were identified through a literature search of Ovid Medline (1948-2011). The FCM approach was used to identify the key variables that have the most influence in a HIA. Changes in air-tightness, ventilation, indoor air quality and mould/humidity have been identified as having the most influence on health. The FCM approach is widely applicable and can be used to inform the formulation of the framing assumptions in any quantitative HIA of environmental interventions. We argue that it is necessary to explore and quantify framing assumptions prior to conducting a detailed quantitative HIA during the assessment stage. Copyright © 2013 Elsevier Ltd.

  19. Nitrates in ground and drinking water: analysis of policies and regulations

    Energy Technology Data Exchange (ETDEWEB)

    Conrad, J

    1986-05-01

    On the societal level, risks are the result of collective processes of definition. Accepted risks are mainly the output and secondarily the (scientific) input of these processes. As a consequence, in this paper the question of risk management of the nitrate burden to ground and drinking water is analysed within the framework of comparative policy analysis. Various actors pursue their respective interests in different policy arenas within the given rules of the policy game. The impacts of the policy outputs on the policy addressees, namely farmers and water companies, (substantially) determine the level of actual risk. Different national regulatory styles and traditions towards nitrate regulation shape the policy outputs. Consequently, the assumption or normative postulate of a rational (scientific) risk assessment and risk management appears to be utterly heroic and, in the end, misleading.

  20. A statistical test of the stability assumption inherent in empirical estimates of economic depreciation.

    Shriver, K A

    1986-01-01

    Realistic estimates of economic depreciation are required for analyses of tax policy, economic growth and production, and national income and wealth. THe purpose of this paper is to examine the stability assumption underlying the econometric derivation of empirical estimates of economic depreciation for industrial machinery and and equipment. The results suggest that a reasonable stability of economic depreciation rates of decline may exist over time. Thus, the assumption of a constant rate of economic depreciation may be a reasonable approximation for further empirical economic analyses.

  2. Optimal Policies for Random and Periodic Garbage Collections with Tenuring Threshold

    Science.gov (United States)

    Zhao, Xufeng; Nakamura, Syouji; Nakagawa, Toshio

    It is an important problem to determine the tenuring threshold to meet the pause time goal for a generational garbage collector. From such viewpoint, this paper proposes two stochastic models based on the working schemes of a generational garbage collector: One is random collection which occurs at a nonhomogeneous Poisson process and the other is periodic collection which occurs at periodic times. Since the cost suffered for minor collection increases, as the amount of surviving objects accumulates, tenuring minor collection should be made at some tenuring threshold. Using the techniques of cumulative processes and reliability theory, expected cost rates with tenuring threshold are obtained, and optimal policies which minimize them are discussed analytically and computed numerically.

  3. Reliability of community health worker collected data for planning and policy in a peri-urban area of Kisumu, Kenya.

    Otieno, C F; Kaseje, D; Ochieng', B M; Githae, M N

    2012-02-01

    A general introduction of this article is as follows: Reliable and timely health information is an essential foundation of public health action and health systems strengthening, both nationally and internationally (Aqil et al. in Health Policy Plan 24(3): 217-228, 2009; Bradshaw et al. in initial burden of disease estimates for South Africa, 2000. South African Medical Research Council, Cape Town, 2003). The need for sound information is especially urgent in the case of emergent diseases and other acute health threats, where rapid awareness, investigation and response can save lives and prevent broader national outbreaks and even global pandemics (Aqil et al. in Health Policy Plan 24(3): 217-228, 2009). The government of Kenya, through the ministry of public health and sanitation has rolled out the community health strategy as a way of improving health care at the household level. This involves community health workers collecting health status data at the household level, which is then used for dialogue at all the levels to inform decisions and actions towards improvement in health status. A lot of health interventions have involved the community health workers in reaching out to the community, hence successfully implementing these health interventions. Large scale involvement of community health workers in government initiatives and most especially to collect health data for use in the health systems has been minimal due to the assumption that the data may not be useful to the government, because its quality is uncertain. It was therefore necessary that the validity and reliability of the data collected by community health workers be determined, and whether this kind of data can be used for planning and policy formulation for the communities from which it is collected. This would go a long way to settle speculation on whether the data collected by these workers is valid and reliable for use in determining the health status, its causes and distribution, of a

  4. Shattering world assumptions: A prospective view of the impact of adverse events on world assumptions.

    Schuler, Eric R; Boals, Adriel

    2016-05-01

    Shattered Assumptions theory (Janoff-Bulman, 1992) posits that experiencing a traumatic event has the potential to diminish the degree of optimism in the assumptions of the world (assumptive world), which could lead to the development of posttraumatic stress disorder. Prior research assessed the assumptive world with a measure that was recently reported to have poor psychometric properties (Kaler et al., 2008). The current study had 3 aims: (a) to assess the psychometric properties of a recently developed measure of the assumptive world, (b) to retrospectively examine how prior adverse events affected the optimism of the assumptive world, and (c) to measure the impact of an intervening adverse event. An 8-week prospective design with a college sample (N = 882 at Time 1 and N = 511 at Time 2) was used to assess the study objectives. We split adverse events into those that were objectively or subjectively traumatic in nature. The new measure exhibited adequate psychometric properties. The report of a prior objective or subjective trauma at Time 1 was related to a less optimistic assumptive world. Furthermore, participants who experienced an intervening objectively traumatic event evidenced a decrease in optimistic views of the world compared with those who did not experience an intervening adverse event. We found support for Shattered Assumptions theory retrospectively and prospectively using a reliable measure of the assumptive world. We discuss future assessments of the measure of the assumptive world and clinical implications to help rebuild the assumptive world with current therapies.

  6. False assumptions.

    Science.gov (United States)

    Swaminathan, M

    1997-01-01

    Indian women do not have to be told the benefits of breast feeding or "rescued from the clutches of wicked multinational companies" by international agencies. There is no proof that breast feeding has declined in India; in fact, a 1987 survey revealed that 98% of Indian women breast feed. Efforts to promote breast feeding among the middle classes rely on such initiatives as the "baby friendly" hospital where breast feeding is promoted immediately after birth. This ignores the 76% of Indian women who give birth at home. Blaming this unproved decline in breast feeding on multinational companies distracts attention from more far-reaching and intractable effects of social change. While the Infant Milk Substitutes Act is helpful, it also deflects attention from more pressing issues. Another false assumption is that Indian women are abandoning breast feeding to comply with the demands of employment, but research indicates that most women give up employment for breast feeding, despite the economic cost to their families. Women also seek work in the informal sector to secure the flexibility to meet their child care responsibilities. Instead of being concerned about "teaching" women what they already know about the benefits of breast feeding, efforts should be made to remove the constraints women face as a result of their multiple roles and to empower them with the support of families, governmental policies and legislation, employers, health professionals, and the media.

  7. Pricing and sales tax collection policies for e-cigarette starter kits and disposable products sold online.

    2015-10-23

    Previous studies have examined marketing characteristics of e-cigarettes sold online and others have examined e-cigarettes pricing in retail (non-Internet) settings. This study expands on these findings by examining pricing and marketing characteristics of interest among e-cigarette online vendors. Structured web searches were conducted from August-September 2014 to identify popular e-cigarette Internet vendors. We then collected pricing data (e-cigarette starter kits and disposables), sales tax collection policies and other vendor marketing characteristics. Average price for each product category was then compared with marketing characteristics using linear regression for continuous variables and independent t-tests for binary variables. Our searches yielded 44 e-cigarette Internet vendors of which 77% (n = 34) sold a total of 238 starter kit offerings (Mprice = $55.89). Half (n = 22) sold disposable types of e-cigarettes (Mprice = $7.17 p/e-cigarette) at a price lower than reported elsewhere in retail settings. Average disposable e-cigarette prices were also significantly higher for vendors displaying more health warning notices (P = 0.001). Only 46% disclosed sales tax collection policies and only 39% collected sales tax in their state of business. This study expands on current understanding of e-cigarette pricing and availability online and finds variation in e-cigarette pricing may be influenced by type of product, use of online health warnings and vendor sales tax collection policies. It also finds that e-cigarette online access and availability may be impacted by a combination of pricing and marketing strategies uniquely different from e-cigarette retail settings that requires further study and targeted policy-making.

  11. Renewable resource policy when distributional impacts matter

    International Nuclear Information System (INIS)

    Horan, R.D.; Shortle, J.S.; Bulte, E.H.

    1999-01-01

    The standard assumption in bioeconomic resource models is that optimal policies maximize the present value of economic surplus to society. This assumption implies that regulatory agencies should not be concerned with the distributional consequences of management strategies. Both contemporary welfare-theoretic and rent-seeking approaches suggests distributional issues are important in designing resource management policies. This paper explores resource management when the managing agency has preferences defined over the economic welfare of various groups with a direct economic interest in the use of resources. Policy schemes consistent with this approach are derived and compared with standard results. 42 refs

  12. Estimators for longitudinal latent exposure models: examining measurement model assumptions.

    Science.gov (United States)

    Sánchez, Brisa N; Kim, Sehee; Sammel, Mary D

    2017-06-15

    Latent variable (LV) models are increasingly being used in environmental epidemiology as a way to summarize multiple environmental exposures and thus minimize statistical concerns that arise in multiple regression. LV models may be especially useful when multivariate exposures are collected repeatedly over time. LV models can accommodate a variety of assumptions but, at the same time, present the user with many choices for model specification particularly in the case of exposure data collected repeatedly over time. For instance, the user could assume conditional independence of observed exposure biomarkers given the latent exposure and, in the case of longitudinal latent exposure variables, time invariance of the measurement model. Choosing which assumptions to relax is not always straightforward. We were motivated by a study of prenatal lead exposure and mental development, where assumptions of the measurement model for the time-changing longitudinal exposure have appreciable impact on (maximum-likelihood) inferences about the health effects of lead exposure. Although we were not particularly interested in characterizing the change of the LV itself, imposing a longitudinal LV structure on the repeated multivariate exposure measures could result in high efficiency gains for the exposure-disease association. We examine the biases of maximum likelihood estimators when assumptions about the measurement model for the longitudinal latent exposure variable are violated. We adapt existing instrumental variable estimators to the case of longitudinal exposures and propose them as an alternative to estimate the health effects of a time-changing latent predictor. We show that instrumental variable estimators remain unbiased for a wide range of data generating models and have advantages in terms of mean squared error. Copyright © 2017 John Wiley & Sons, Ltd.

  13. Bell violation using entangled photons without the fair-sampling assumption.

    The violation of a Bell inequality is an experimental observation that forces the abandonment of a local realistic viewpoint--namely, one in which physical properties are (probabilistically) defined before and independently of measurement, and in which no physical influence can propagate faster than the speed of light. All such experimental violations require additional assumptions depending on their specific construction, making them vulnerable to so-called loopholes. Here we use entangled photons to violate a Bell inequality while closing the fair-sampling loophole, that is, without assuming that the sample of measured photons accurately represents the entire ensemble. To do this, we use the Eberhard form of Bell's inequality, which is not vulnerable to the fair-sampling assumption and which allows a lower collection efficiency than other forms. Technical improvements of the photon source and high-efficiency transition-edge sensors were crucial for achieving a sufficiently high collection efficiency. Our experiment makes the photon the first physical system for which each of the main loopholes has been closed, albeit in different experiments.

Law and policy analysis. Alabama, California, Florida, Georgia, Hawaii, Massachusetts, Michigan, Minnesota, New Jersey, New York, Ohio, Oregon, Rhode Island, South Carolina, Washington, and Wisconsin. Information on syringe collection and disposal in the community was gathered from federal and state records and state agency personnel. Legally permissible means of syringe collection and disposal available to persons in the community injecting medical treatments and injection drug users. Laws, regulations, or guidelines in 13 states allowed community syringes to be legally discarded in household trash; guidelines for in-trash disposal varied among the states. Only 6 states had laws or regulations that specifically addressed community syringe collection. In 10 states, infectious waste laws and regulations that apply to medical facilities such as clinics would also apply to community syringe collection sites. In the 16 states studied, laws, regulations, and guidelines relating to community syringe collection and disposal were somewhat inconsistent and confusing and presented potential barriers to safe disposal. States should consider amending laws, regulations, and guidelines to promote community syringe collection programs. A national effort is needed to achieve consistent community syringe collection and disposal laws and guidelines for all states. Pharmacists can aid in safe syringe disposal by counseling their patients about safe disposal, providing or selling sharps containers, and accepting used syringes for safe disposal. Pharmacists can join other interested groups in advocating clarification of disposal laws and regulations that favor community programs designed to keep syringes out of the trash so that they can be disposed of as

    Gentil, Emmanuel; Damgaard, Anders; Hauschild, Michael Zwicky

    2010-01-01

    A number of waste life cycle assessment (LCA) models have been gradually developed since the early 1990s, in a number of countries, usually independently from each other. Large discrepancies in results have been observed among different waste LCA models, although it has also been shown that results...... from different LCA studies can be consistent. This paper is an attempt to identify, review and analyse methodologies and technical assumptions used in various parts of selected waste LCA models. Several criteria were identified, which could have significant impacts on the results......, such as the functional unit, system boundaries, waste composition and energy modelling. The modelling assumptions of waste management processes, ranging from collection, transportation, intermediate facilities, recycling, thermal treatment, biological treatment, and landfilling, are obviously critical when comparing...

  20. Linear regression and the normality assumption.

    Science.gov (United States)

    Schmidt, Amand F; Finan, Chris

    2017-12-16

    Researchers often perform arbitrary outcome transformations to fulfill the normality assumption of a linear regression model. This commentary explains and illustrates that in large data settings, such transformations are often unnecessary, and worse may bias model estimates. Linear regression assumptions are illustrated using simulated data and an empirical example on the relation between time since type 2 diabetes diagnosis and glycated hemoglobin levels. Simulation results were evaluated on coverage; i.e., the number of times the 95% confidence interval included the true slope coefficient. Although outcome transformations bias point estimates, violations of the normality assumption in linear regression analyses do not. The normality assumption is necessary to unbiasedly estimate standard errors, and hence confidence intervals and P-values. However, in large sample sizes (e.g., where the number of observations per variable is >10) violations of this normality assumption often do not noticeably impact results. Contrary to this, assumptions on, the parametric model, absence of extreme observations, homoscedasticity, and independency of the errors, remain influential even in large sample size settings. Given that modern healthcare research typically includes thousands of subjects focusing on the normality assumption is often unnecessary, does not guarantee valid results, and worse may bias estimates due to the practice of outcome transformations.

  3. I Assumed You Knew: Teaching Assumptions as Co-Equal to Observations in Scientific Work

    Science.gov (United States)

    Horodyskyj, L.; Mead, C.; Anbar, A. D.

    2016-12-01

    Introductory science curricula typically begin with a lesson on the "nature of science". Usually this lesson is short, built with the assumption that students have picked up this information elsewhere and only a short review is necessary. However, when asked about the nature of science in our classes, student definitions were often confused, contradictory, or incomplete. A cursory review of how the nature of science is defined in a number of textbooks is similarly inconsistent and excessively loquacious. With such confusion both from the student and teacher perspective, it is no surprise that students walk away with significant misconceptions about the scientific endeavor, which they carry with them into public life. These misconceptions subsequently result in poor public policy and personal decisions on issues with scientific underpinnings. We will present a new way of teaching the nature of science at the introductory level that better represents what we actually do as scientists. Nature of science lessons often emphasize the importance of observations in scientific work. However, they rarely mention and often hide the importance of assumptions in interpreting those observations. Assumptions are co-equal to observations in building models, which are observation-assumption networks that can be used to make predictions about future observations. The confidence we place in these models depends on whether they are assumption-dominated (hypothesis) or observation-dominated (theory). By presenting and teaching science in this manner, we feel that students will better comprehend the scientific endeavor, since making observations and assumptions and building mental models is a natural human behavior. We will present a model for a science lab activity that can be taught using this approach.

  4. Multiverse Assumptions and Philosophy

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Multiverses are predictions based on theories. Focusing on each theory’s assumptions is key to evaluating a proposed multiverse. Although accepted theories of particle physics and cosmology contain non-intuitive features, multiverse theories entertain a host of “strange” assumptions classified as metaphysical (outside objective experience, concerned with fundamental nature of reality, ideas that cannot be proven right or wrong topics such as: infinity, duplicate yous, hypothetical fields, more than three space dimensions, Hilbert space, advanced civilizations, and reality established by mathematical relationships. It is easy to confuse multiverse proposals because many divergent models exist. This overview defines the characteristics of eleven popular multiverse proposals. The characteristics compared are: initial conditions, values of constants, laws of nature, number of space dimensions, number of universes, and fine tuning explanations. Future scientific experiments may validate selected assumptions; but until they do, proposals by philosophers may be as valid as theoretical scientific theories.

  5. Sensitivity Analysis Without Assumptions.

    Science.gov (United States)

    Ding, Peng; VanderWeele, Tyler J

    2016-05-01

    Unmeasured confounding may undermine the validity of causal inference with observational studies. Sensitivity analysis provides an attractive way to partially circumvent this issue by assessing the potential influence of unmeasured confounding on causal conclusions. However, previous sensitivity analysis approaches often make strong and untestable assumptions such as having an unmeasured confounder that is binary, or having no interaction between the effects of the exposure and the confounder on the outcome, or having only one unmeasured confounder. Without imposing any assumptions on the unmeasured confounder or confounders, we derive a bounding factor and a sharp inequality such that the sensitivity analysis parameters must satisfy the inequality if an unmeasured confounder is to explain away the observed effect estimate or reduce it to a particular level. Our approach is easy to implement and involves only two sensitivity parameters. Surprisingly, our bounding factor, which makes no simplifying assumptions, is no more conservative than a number of previous sensitivity analysis techniques that do make assumptions. Our new bounding factor implies not only the traditional Cornfield conditions that both the relative risk of the exposure on the confounder and that of the confounder on the outcome must satisfy but also a high threshold that the maximum of these relative risks must satisfy. Furthermore, this new bounding factor can be viewed as a measure of the strength of confounding between the exposure and the outcome induced by a confounder.

  7. Monitoring Assumptions in Assume-Guarantee Contracts

    Directory of Open Access Journals (Sweden)

    Oleg Sokolsky

    2016-05-01

    Full Text Available Pre-deployment verification of software components with respect to behavioral specifications in the assume-guarantee form does not, in general, guarantee absence of errors at run time. This is because assumptions about the environment cannot be discharged until the environment is fixed. An intuitive approach is to complement pre-deployment verification of guarantees, up to the assumptions, with post-deployment monitoring of environment behavior to check that the assumptions are satisfied at run time. Such a monitor is typically implemented by instrumenting the application code of the component. An additional challenge for the monitoring step is that environment behaviors are typically obtained through an I/O library, which may alter the component's view of the input format. This transformation requires us to introduce a second pre-deployment verification step to ensure that alarms raised by the monitor would indeed correspond to violations of the environment assumptions. In this paper, we describe an approach for constructing monitors and verifying them against the component assumption. We also discuss limitations of instrumentation-based monitoring and potential ways to overcome it.

    2014-01-01

    We develop the case for symmetrical assumptions in strategic management theory. Assumptional symmetry obtains when assumptions made about certain actors and their interactions in one of the application domains of a theory are also made about this set of actors and their interactions in other...... application domains of the theory. We argue that assumptional symmetry leads to theoretical advancement by promoting the development of theory with greater falsifiability and stronger ontological grounding. Thus, strategic management theory may be advanced by systematically searching for asymmetrical...

  11. Moving from assumption to observation: Implications for energy and emissions impacts of plug-in hybrid electric vehicles

    International Nuclear Information System (INIS)

    Davies, Jamie; Kurani, Kenneth S.

    2013-01-01

    Plug-in hybrid electric vehicles (PHEVs) are currently for sale in most parts of the United States, Canada, Europe and Japan. These vehicles are promoted as providing distinct consumer and public benefits at the expense of grid electricity. However, the specific benefits or impacts of PHEVs ultimately relies on consumers purchase and vehicle use patterns. While considerable effort has been dedicated to understanding PHEV impacts on a per mile basis few studies have assessed the impacts of PHEV given actual consumer use patterns or operating conditions. Instead, simplifying assumptions have been made about the types of cars individual consumers will choose to purchase and how they will drive and charge them. Here, we highlight some of these consumer purchase and use assumptions, studies which have employed these assumptions and compare these assumptions to actual consumer data recorded in a PHEV demonstration project. Using simulation and hypothetical scenarios we discuss the implication for PHEV impact analyses and policy if assumptions about key PHEV consumer use variables such as vehicle choice, home charging frequency, distribution of driving distances, and access to workplace charging were to change. -- Highlights: •The specific benefits or impacts of PHEVs ultimately relies on consumers purchase and vehicle use patterns. •Simplifying, untested, assumptions have been made by prior studies about PHEV consumer driving, charging and vehicle purchase behaviors. •Some simplifying assumptions do not match observed data from a PHEV demonstration project. •Changing the assumptions about PHEV consumer driving, charging, and vehicle purchase behaviors affects estimates of PHEV impacts. •Premature simplification may have lasting consequences for standard setting and performance based incentive programs which rely on these estimates

  14. The European Water Framework Directive: How Ecological Assumptions Frame Technical and Social Change

    Directory of Open Access Journals (Sweden)

    Patrick Steyaert

    2007-06-01

    Full Text Available The European Water Framework Directive (WFD is built upon significant cognitive developments in the field of ecological science but also encourages active involvement of all interested parties in its implementation. The coexistence in the same policy text of both substantive and procedural approaches to policy development stimulated this research as did our concerns about the implications of substantive ecological visions within the WFD policy for promoting, or not, social learning processes through participatory designs. We have used a qualitative analysis of the WFD text which shows the ecological dimension of the WFD dedicates its quasi-exclusive attention to a particular current of thought in ecosystems science focusing on ecosystems status and stability and considering human activities as disturbance factors. This particular worldview is juxtaposed within the WFD with a more utilitarian one that gives rise to many policy exemptions without changing the general underlying ecological model. We discuss these policy statements in the light of the tension between substantive and procedural policy developments. We argue that the dominant substantive approach of the WFD, comprising particular ecological assumptions built upon "compositionalism," seems to be contradictory with its espoused intention of involving the public. We discuss that current of thought in regard to more functionalist thinking and adaptive management, which offers greater opportunities for social learning, i.e., place a set of interdependent stakeholders in an intersubjective position in which they operate a "social construction" of water problems through the co-production of knowledge.

    Full Text Available Objective – To explore how collection development policies currently support the role and purpose of prison libraries, and to explore if the accessibility of circulation records impacts on patron privacy.Design – Online survey questionnaire and a case study analysis of the existing policy statements of selected correctional institutions.Setting – The prison library sector in the United States.Subjects – 17 librarians and library staff across ten states in the United States.Methods – An eight-question online questionnaire was used to explore the existing collection development and circulation policies in prison libraries, and the level of adherence to the guidelines of the Association of Specialized and Cooperative Library Agencies (ASCLA and the American Correctional Association (ACA. In addition, participants were encouraged to forward any circulation or collection development policy statements for more detailed analysis. Each policy was then reviewed to assess the degree of alignment or otherwise with the American Library Association’s (ALA Prisoners’ Right to Read guidelines (2010.Main Results – The results of the survey found that 24% of libraries had no formal collection development policy, and at least 53% of libraries had no circulation policy statement. In these instances, the libraries were typically subject to the local policies and procedures of the correctional institution. The purpose of the library and its collection was primarily viewed as: providing recreational reading material; maintaining contact with the outside world and enabling re-entry into the community; and supporting vocational skills and lifelong learning. In selecting materials, the results indicated that a broadly similar approach to that of public libraries was adopted by most institutions, with the exception of any material that may pose a safety or security threat to the institution.

    Aakhus, Mark

    2011-11-01

    The International Radiation Protection Association's guiding principles for stakeholder engagement focus on fostering, facilitating, and enabling interaction among stakeholders that is inclusive and fosters competent decision making. Implicit in these standards is a call to cultivate knowledge and competence in designing communication for stakeholder engagement among radiation protection professionals. Communication as design is an approach to risk communication in science and policy that differs from, yet complements, the more well-known communication practices of informing and persuading. Design focuses on the recurring practical problem faced by professionals in making communication possible among stakeholders where it has otherwise been difficult, impossible, or even unimagined. The knowledge and competence associated with design involves principles for crafting interactivity across a variety of mediated and non-mediated encounters among stakeholders. Risk communication can be improved by cultivating expertise in scalable communication design that embraces the demands of involvement without abandoning the need for competence in science and policy communication.

  4. Evaluating methodological assumptions of a catch-curve survival estimation of unmarked precocial shorebird chickes

    Science.gov (United States)

    McGowan, Conor P.; Gardner, Beth

    2013-01-01

    Estimating productivity for precocial species can be difficult because young birds leave their nest within hours or days of hatching and detectability thereafter can be very low. Recently, a method for using a modified catch-curve to estimate precocial chick daily survival for age based count data was presented using Piping Plover (Charadrius melodus) data from the Missouri River. However, many of the assumptions of the catch-curve approach were not fully evaluated for precocial chicks. We developed a simulation model to mimic Piping Plovers, a fairly representative shorebird, and age-based count-data collection. Using the simulated data, we calculated daily survival estimates and compared them with the known daily survival rates from the simulation model. We conducted these comparisons under different sampling scenarios where the ecological and statistical assumptions had been violated. Overall, the daily survival estimates calculated from the simulated data corresponded well with true survival rates of the simulation. Violating the accurate aging and the independence assumptions did not result in biased daily survival estimates, whereas unequal detection for younger or older birds and violating the birth death equilibrium did result in estimator bias. Assuring that all ages are equally detectable and timing data collection to approximately meet the birth death equilibrium are key to the successful use of this method for precocial shorebirds.

  9. Divestment prevails over the green paradox when anticipating strong future climate policies

    Science.gov (United States)

    Bauer, Nico; McGlade, Christophe; Hilaire, Jérôme; Ekins, Paul

    2018-01-01

    Fossil fuel market dynamics will have a significant impact on the effectiveness of climate policies1. Both fossil fuel owners and investors in fossil fuel infrastructure are sensitive to climate policies that threaten their natural resource endowments and production capacities2-4, which will consequently affect their near-term behaviour. Although weak in near-term policy commitments5,6, the Paris Agreement on climate7 signalled strong ambitions in climate change stabilization. Many studies emphasize that the 2 °C target can still be achieved even if strong climate policies are delayed until 20308-10. However, sudden implementation will have severe consequences for fossil fuel markets and beyond and these studies ignore the anticipation effects of owners and investors. Here we use two energy-economy models to study the collective influence of the two central but opposing anticipation arguments, the green paradox11 and the divestment effect12, which have, to date, been discussed only separately. For a wide range of future climate policies, we find that anticipation effects, on balance, reduce CO2 emissions during the implementation lag. This is because of strong divestment in coal power plants starting ten years ahead of policy implementation. The green paradox effect is identified, but is small under reasonable assumptions.

  10. Crisis and Policy Reformcraft: Advocacy Coalitions and Crisis-induced Change in Swedish Nuclear Energy Policy

    Energy Technology Data Exchange (ETDEWEB)

    Nohrstedt, Daniel

    2007-04-15

    This dissertation consists of three interrelated essays examining the role of crisis events in Swedish nuclear energy policymaking. The study takes stock of the idea of 'crisis exceptionalism' raised in the literature, which postulates that crisis events provide openings for major policy change. In an effort to explain crisis-induced outcomes in Swedish nuclear energy policy, each essay explores and develops theoretical assumptions derived from the Advocacy Coalition Framework (ACF). The introduction discusses the ACF and other theoretical perspectives accentuating the role of crisis in policymaking and identifies three explanations for crisis-induced policy outcomes: minority coalition mobilization, learning, and strategic action. Essay 1 analyzes the nature and development of the Swedish nuclear energy subsystem. The results contradict the ACF assumption that corporatist systems nurture narrow subsystems and small advocacy coalitions, but corroborate the assumption that advocacy coalitions remain stable over time. While this analysis identifies temporary openings in policymaking venues and in the advocacy coalition structure, it is argued that these developments did not affect crisis policymaking. Essay 2 seeks to explain the decision to initiate a referendum on nuclear power following the 1979 Three Mile Island accident. Internal government documents and other historical records indicate that strategic considerations superseded learning as the primary explanation in this case. Essay 3 conducts an in-depth examination of Swedish policymaking in the aftermath of the 1986 Chernobyl accident in an effort to explain the government's decision not to accelerate the nuclear power phaseout. Recently disclosed government documents show that minority coalition mobilization was insufficient to explain this decision. In this case, rational learning and strategic action provided a better explanation. The main theoretical contribution derived from the three

Recently disclosed government documents show that minority coalition mobilization was insufficient to explain this decision. In this case, rational learning and strategic action provided a better explanation. The main theoretical contribution derived from the three essays is to posit

  12. Social Cost Benefit Analysis for Environmental Policy-Making

    Review of the theoretical literature and the current debate on the valuation of environmental goods and services, on the discounting of future benefits and costs, and on how social cost benefit analysis (SCBAs) can be integrated in the policy and decision making process. It is concluded that SCBA can be a good decision support method in environmental policy-making if it is transparent and if all impacts are taken into account. Furthermore, the SCBA process should be participative, and politicians must be prepared to take responsibility for the assumptions behind the SCBA, including the assumptions on valuation and on the discount rate. Such a political role makes each SCBA a unique product of a politically responsible actor, and makes it possible for other stakeholders to have calculated an alternative SCBA based on their own assumptions. This Background Study also contains the proceedings of the international SCBA conference organised by RMNO on 16-17 January 2008

  13. Can a policy program influence policy change? The case of the Swiss EnergieSchweiz program

    Sager, Fritz; Bürki, Marietta; Luginbühl, Jennifer

    2014-01-01

    This paper investigates the interrelation of policy implementation and policy change by addressing the question of whether and how the Swiss energy program “EnergieSchweiz” influenced policy decisions. We discuss different ways in which a policy program may influence policy change: by negative and positive learning, by coalition building and by policy community building. Respective assumptions are tested in two case studies from the “EnergieSchweiz” program, which was in place from 2000 to 2010. We find that, while the policy program was not critical for the policy change itself, it nevertheless played a role as an agenda setter, as an initiator of learning processes as well as through its policy community. - Highlights: • We investigate how energy policy implementation impacts policy change. • We analyse the Swiss energy program “EnergieSchweiz” in place from 2000 to 2010. • Policy programs alone do not deliver policy change. • But they can influence it by agenda setting and by negative learning. • Expert networks have an influence if there are shared goals

  14. Robust policy choice under Calvo and Rotemberg pricing

    2012-01-01

    This paper examines the robustness of welfare-based policy choices across the nonlinear Calvo and Rotemberg pricing assumptions. Comparisons between simple interest rate rules turn out to be robust and independent of the price dispersion inherent in the Calvo setting. This robustness is violated if there is a policy alternative that controls for price dispersion.

  15. Concepts of collective dose in radiological protection

    International Nuclear Information System (INIS)

    Lindell, B.

    1985-01-01

    The collective dose (S) is the product of the number of individuals exposed and their average radiation dose. ''Radiation dose'' is usually taken to be the effective dose equivalent (Hsub(E)) as defined by the ICRP. The unit of the collective dose is then the man.sievert (man.Sv). The following four applications of the collective dose are the most common: (a) in the assessment of the highest per caput dose rate in the future from a continued practice which exposes some critical group or the population as a whole to radiation; (b) in the limitation of present radiation sources, if it is believed that additional sources in the future may add to the per caput dose in a population so that it might reach unacceptable levels unless all sources are controlled at an early stage; (c) as an input to justification assessments, indicating the total detriment from a certain practice; and (d) as an input to optimization assessments as the basis for costing detriment in differential cost-benefit analyses of protection arrangements. It is sometimes said that the collective dose is a useful quantity only if the assumption of a non-threshold, linear dose-response relation is valid. This assumption is not always necessary. Applications (a) and (b) are possible without any assumption on the dose-response relationship at very low doses. Only applications (c) and (d) require the assumption of a non-threshold, linear dose-response relation. Some hesitation in using the collective dose originates in distrust in the biological assumptions implied by uses (c) and (d), but also in lack of confidence in the meaningfulness of collective doses that have been derived by adding dose contributions over very long time periods. However, none of the four applications (a) - (d) is by necessity related to extreme time scales. That problem mainly arises in the assessment of radioactive waste repositories

  18. Weighing the Costs and Benefits of Renewables Portfolio Standards:A Comparative Analysis of State-Level Policy Impact Projections

    Energy Technology Data Exchange (ETDEWEB)

    Chen, Cliff; Wiser, Ryan; Bolinger, Mark

    2007-01-16

    State renewables portfolio standards (RPS) have emerged as one of the most important policy drivers of renewable energy capacity expansion in the U.S. Collectively, these policies now apply to roughly 40% of U.S. electricity load, and may have substantial impacts on electricity markets, ratepayers, and local economies. As RPS policies have been proposed or adopted in an increasing number of states, a growing number of studies have attempted to quantify the potential impacts of these policies, focusing primarily on projecting cost impacts, but sometimes also estimating macroeconomic and environmental effects. This report synthesizes and analyzes the results and methodologies of 28 distinct state or utility-level RPS cost impact analyses completed since 1998. Together, these studies model proposed or adopted RPS policies in 18 different states. We highlight the key findings of these studies on the costs and benefits of RPS policies, examine the sensitivity of projected costs to model assumptions, assess the attributes of different modeling approaches, and suggest possible areas of improvement for future RPS analysis.

    2000-06-01

    To investigate assumptions and beliefs in anorexia nervosa and dieting. The Eating Disorder Belief Questionnaire (EDBQ), was administered to patients with anorexia nervosa, dieters and female controls. The patients scored more highly than the other two groups on assumptions about weight and shape, assumptions about eating and negative self-beliefs. The dieters scored more highly than the female controls on assumptions about weight and shape. The cognitive content of anorexia nervosa (both assumptions and negative self-beliefs) differs from that found in dieting. Assumptions about weight and shape may also distinguish dieters from female controls.

    1996-04-01

    In October, 1993, 16 months after the United Nations approved the International Convention on Biodiversity held in Rio de Janeiro, June, 1992, the Philippine Congress ratified and adopted the Convention. This is a manifestation of the full support of the Philippines for the principles and policies adopted by the UN body on the conservation of biodiversity, sustainable development of biological resources and equitable sharing of benefits between users and owners of biodiversity resources. The Philippine scientific community has long recognized the need for and importance of a national guideline and policy with regard to the collection of plants and animals in the Philippines for scientific or commercial purposes. A series of consultative meetings were held by representatives of government agencies, non-government organizations, private organizations, academic and private persons concerned with biodiversity conservation to formulate national guidelines that regulate the collection of plant and animal specimens in the country. Guidelines were unanimously adopted by various government agencies and academia and a Memorandum of Agreement (MOA) was signed on September 28, 1990. Very recently a new document was drafted, specifically to serve as a guideline for those who desire to undertake sample collecting in the Philippines for biodiversity prospecting. The document is now being reviewed by government departments and agencies and will be presented to the President of the Philippines for signing as an Executive Order (EO). Once signed, this EO will serve as a national policy for bioprospecting in the country. The Philippines is one of the countries in Southeast Asia that has endorsed the adoption of regional guidelines on the collection of plant and animal organisms for drug development.

  8. Are implicit policy assumptions about climate adaptation trying to push drinking water utilities down an impossible path?

    Science.gov (United States)

    Klasic, M. R.; Ekstrom, J.; Bedsworth, L. W.; Baker, Z.

    2017-12-01

    Extreme events such as wildfires, droughts, and flooding are projected to be more frequent and intense under a changing climate, increasing challenges to water quality management. To protect and improve public health, drinking water utility managers need to understand and plan for climate change and extreme events. This three year study began with the assumption that improved climate projections were key to advancing climate adaptation at the local level. Through a survey (N = 259) and interviews (N = 61) with California drinking water utility managers during the peak of the state's recent drought, we found that scientific information was not a key barrier hindering adaptation. Instead, we found that managers fell into three distinct mental models based on their interaction with, perceptions, and attitudes, towards scientific information and the future of water in their system. One of the mental models, "modeled futures", is a concept most in line with how climate change scientists talk about the use of information. Drinking water utilities falling into the "modeled future" category tend to be larger systems that have adequate capacity to both receive and use scientific information. Medium and smaller utilities in California, that more often serve rural low income communities, tend to fall into the other two mental models, "whose future" and "no future". We show evidence that there is an implicit presumption that all drinking water utility managers should strive to align with "modeled future" mental models. This presentation questions this assumption as it leaves behind many utilities that need to adapt to climate change (several thousand in California alone), but may not have the technical, financial, managerial, or other capacity to do so. It is clear that no single solution or pathway to drought resilience exists for water utilities, but we argue that a more explicit understanding and definition of what it means to be a resilient drinking water utility is

    Resnik, David B

    2015-06-01

    Government food and beverage policies can play an important role in promoting public health. Few people would question this assumption. Difficult questions can arise, however, when policymakers, public health officials, citizens, and businesses deliberate about food and beverage policies, because competing values may be at stake, such as public health, individual autonomy, personal responsibility, economic prosperity, and fairness. An ethically justified policy strikes a reasonable among competing values by meeting the following criteria: (1) the policy serves important social goal(s); (2) the policy is likely to be effective at achieving those goal(s); (3) less burdensome options are not likely to be effective at achieving the goals; (4) the policy is fair.

  13. Transformation of Croatian Disabled Policy: Analysis of Policy Goals

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available The article is based on the idea of transformation of the policy-making mode of Croatian disabled policy, from the medical model, through the social model to the human rights model. The paper highlights 7 elements according to which these models differ, and which are structured into categories of problem-definition, goal-determination and then implementation of disabled policy. The analysis is focused on the goals of Croatian disabled policy, and is based on an interdisciplinary research project of political science, special education and social work. Empirical data were collected by document analysis, by interviewing relevant policy actors and by a survey with the members of representative bodies on all government levels. With the discourse analysis of documents, open coding of interviews and statistical analysis of data collected in the survey, the paper attempts, through the indicator of activity of persons with disability, to answer to what extent Croatian disabled policy is transformed into human rights policy.

  15. Occupancy estimation and the closure assumption

    Science.gov (United States)

    Rota, Christopher T.; Fletcher, Robert J.; Dorazio, Robert M.; Betts, Matthew G.

    2009-01-01

    1. Recent advances in occupancy estimation that adjust for imperfect detection have provided substantial improvements over traditional approaches and are receiving considerable use in applied ecology. To estimate and adjust for detectability, occupancy modelling requires multiple surveys at a site and requires the assumption of 'closure' between surveys, i.e. no changes in occupancy between surveys. Violations of this assumption could bias parameter estimates; however, little work has assessed model sensitivity to violations of this assumption or how commonly such violations occur in nature. 2. We apply a modelling procedure that can test for closure to two avian point-count data sets in Montana and New Hampshire, USA, that exemplify time-scales at which closure is often assumed. These data sets illustrate different sampling designs that allow testing for closure but are currently rarely employed in field investigations. Using a simulation study, we then evaluate the sensitivity of parameter estimates to changes in site occupancy and evaluate a power analysis developed for sampling designs that is aimed at limiting the likelihood of closure. 3. Application of our approach to point-count data indicates that habitats may frequently be open to changes in site occupancy at time-scales typical of many occupancy investigations, with 71% and 100% of species investigated in Montana and New Hampshire respectively, showing violation of closure across time periods of 3 weeks and 8 days respectively. 4. Simulations suggest that models assuming closure are sensitive to changes in occupancy. Power analyses further suggest that the modelling procedure we apply can effectively test for closure. 5. Synthesis and applications. Our demonstration that sites may be open to changes in site occupancy over time-scales typical of many occupancy investigations, combined with the sensitivity of models to violations of the closure assumption, highlights the importance of properly addressing

  17. Contextuality under weak assumptions

    International Nuclear Information System (INIS)

    Simmons, Andrew W; Rudolph, Terry; Wallman, Joel J; Pashayan, Hakop; Bartlett, Stephen D

    2017-01-01

    The presence of contextuality in quantum theory was first highlighted by Bell, Kochen and Specker, who discovered that for quantum systems of three or more dimensions, measurements could not be viewed as deterministically revealing pre-existing properties of the system. More precisely, no model can assign deterministic outcomes to the projectors of a quantum measurement in a way that depends only on the projector and not the context (the full set of projectors) in which it appeared, despite the fact that the Born rule probabilities associated with projectors are independent of the context. A more general, operational definition of contextuality introduced by Spekkens, which we will term ‘probabilistic contextuality’, drops the assumption of determinism and allows for operations other than measurements to be considered contextual. Even two-dimensional quantum mechanics can be shown to be contextual under this generalised notion. Probabilistic noncontextuality represents the postulate that elements of an operational theory that cannot be distinguished from each other based on the statistics of arbitrarily many repeated experiments (they give rise to the same operational probabilities) are ontologically identical. In this paper, we introduce a framework that enables us to distinguish between different noncontextuality assumptions in terms of the relationships between the ontological representations of objects in the theory given a certain relation between their operational representations. This framework can be used to motivate and define a ‘possibilistic’ analogue, encapsulating the idea that elements of an operational theory that cannot be unambiguously distinguished operationally can also not be unambiguously distinguished ontologically. We then prove that possibilistic noncontextuality is equivalent to an alternative notion of noncontextuality proposed by Hardy. Finally, we demonstrate that these weaker noncontextuality assumptions are sufficient to prove

  18. Testing the basic assumption of the hydrogeomorphic approach to assessing wetland functions.

    Science.gov (United States)

    Hruby, T

    2001-05-01

    The hydrogeomorphic (HGM) approach for developing "rapid" wetland function assessment methods stipulates that the variables used are to be scaled based on data collected at sites judged to be the best at performing the wetland functions (reference standard sites). A critical step in the process is to choose the least altered wetlands in a hydrogeomorphic subclass to use as a reference standard against which other wetlands are compared. The basic assumption made in this approach is that wetlands judged to have had the least human impact have the highest level of sustainable performance for all functions. The levels at which functions are performed in these least altered wetlands are assumed to be "characteristic" for the subclass and "sustainable." Results from data collected in wetlands in the lowlands of western Washington suggest that the assumption may not be appropriate for this region. Teams developing methods for assessing wetland functions did not find that the least altered wetlands in a subclass had a range of performance levels that could be identified as "characteristic" or "sustainable." Forty-four wetlands in four hydrogeomorphic subclasses (two depressional subclasses and two riverine subclasses) were rated by teams of experts on the severity of their human alterations and on the level of performance of 15 wetland functions. An ordinal scale of 1-5 was used to quantify alterations in water regime, soils, vegetation, buffers, and contributing basin. Performance of functions was judged on an ordinal scale of 1-7. Relatively unaltered wetlands were judged to perform individual functions at levels that spanned all of the seven possible ratings in all four subclasses. The basic assumption of the HGM approach, that the least altered wetlands represent "characteristic" and "sustainable" levels of functioning that are different from those found in altered wetlands, was not confirmed. Although the intent of the HGM approach is to use level of functioning as a

  1. Limitations to the Dutch cannabis toleration policy: Assumptions underlying the reclassification of cannabis above 15% THC.

    Science.gov (United States)

    Van Laar, Margriet; Van Der Pol, Peggy; Niesink, Raymond

    2016-08-01

    The Netherlands has seen an increase in Δ9-tetrahydrocannabinol (THC) concentrations from approximately 8% in the 1990s up to 20% in 2004. Increased cannabis potency may lead to higher THC-exposure and cannabis related harm. The Dutch government officially condones the sale of cannabis from so called 'coffee shops', and the Opium Act distinguishes cannabis as a Schedule II drug with 'acceptable risk' from other drugs with 'unacceptable risk' (Schedule I). Even in 1976, however, cannabis potency was taken into account by distinguishing hemp oil as a Schedule I drug. In 2011, an advisory committee recommended tightening up legislation, leading to a 2013 bill proposing the reclassification of high potency cannabis products with a THC content of 15% or more as a Schedule I drug. The purpose of this measure was twofold: to reduce public health risks and to reduce illegal cultivation and export of cannabis by increasing punishment. This paper focuses on the public health aspects and describes the (explicit and implicit) assumptions underlying this '15% THC measure', as well as to what extent these are supported by scientific research. Based on scientific literature and other sources of information, we conclude that the 15% measure can provide in theory a slight health benefit for specific groups of cannabis users (i.e., frequent users preferring strong cannabis, purchasing from coffee shops, using 'steady quantities' and not changing their smoking behaviour), but certainly not for all cannabis users. These gains should be weighed against the investment in enforcement and the risk of unintended (adverse) effects. Given the many assumptions and uncertainty about the nature and extent of the expected buying and smoking behaviour changes, the measure is a political choice and based on thin evidence.

  5. The role of organizational culture in policy mobilities – the case of South Korean climate change adaptation policies

    Directory of Open Access Journals (Sweden)

    S. Schäfer

    2017-07-01

    Full Text Available The conceptualization of policies as mobile and mutable knowledge is the key feature of the recent debate on policy mobilities. Policy mobility studies have focused on the movement and translation of policies as well as on the impact of mobile policies on policy-making processes and governed spaces. Given that policy mobilities have mainly been examined in comparable institutional contexts, the current debate has neglected the role of organizational culture in the translation of policies. Organizational culture is understood as a set of shared assumptions that guide what happens in organizations by defining appropriate practices of policy making. The case study, South Korean adaptation policy, illustrates that organizational culture has a significant impact on the translation of mobile adaptation policy. Besides the claim to consider organizational culture more prominently in the field of policy mobility studies, this paper illustrates the translation process of adaptation policy in the South Korean political system. The practices in South Korean political institutions dealing with climate change adaptation are highly characterized by the avoidance of risks. The propensity to avoid risks leads policy makers to focus on technical solutions to climate change adaptation and to neglect the participation of civil society.

    Improving public health requires multiple intervention strategies. Implementing such an intervention mix is supposed to require a multisectoral policy network. As evidence to support this assumption is scarce, we examined under which conditions public health-related policy networks were able to implement an intervention mix. Data were collected (2009-14) from 29 Dutch public health policy networks. Surveys were used to identify the number of policy sectors, participation of actors, level of trust, networking by the project leader, and intervention strategies implemented. Conditions sufficient for an intervention mix (≥3 of 4 non-educational strategies present) were determined in a fuzzy-set qualitative comparative analysis. A multisectoral policy network (≥7 of 14 sectors present) was neither a necessary nor a sufficient condition. In multisectoral networks, additionally required was either the active participation of network actors (≥50% actively involved) or active networking by the project leader (≥monthly contacts with network actors). In policy networks that included few sectors, a high level of trust (positive perceptions of each other's intentions) was needed-in the absence though of any of the other conditions. If the network actors were also actively involved, an extra requirement was active networking by the project leader. We conclude that the multisectoral composition of policy networks can contribute to the implementation of a variety of intervention strategies, but not without additional efforts. However, policy networks that include only few sectors are also able to implement an intervention mix. Here, trust seems to be the most important condition. © The Author 2017.

  8. Devices and desires: population policy and gender roles in the Islamic Republic.

    Hoodfar, H

    1994-01-01

    There is a widely held assumption that Islamist ideology is incompatible with modernity and feminism. Active debate in Iran about the dynamics of population policy and women's rights and responsibilities, together with the government's efforts to build public consensus on the need for birth control and family planning, however, suggest that Islam may be flexible and adaptable in response to political and economic realities. Iranian women individually and collectively have questioned the male interpretation of the proper Islamic role of women. They have encouraged the government to introduce reforms in the areas of marriage, divorce, and education, and are agitating for more improvement in women's legal and social position. These activities indicate that reproductive choices and strategies are not decided by Islam, but are the product of the political and economic realities of a given society. The first population policy of the Islamic Republic was formulated in 1989. Since then, the Family Planning Board has regenerated itself well beyond its pre-revolution capacity in terms of research and public services. Population policy before and after the Islamic Revolution, building national consensus on family planning, the family planning network, women's status, contradictory signals, and women's options are discussed.

  13. A framework for the organizational assumptions underlying safety culture

    International Nuclear Information System (INIS)

    Packer, Charles

    2002-01-01

    The safety culture of the nuclear organization can be addressed at the three levels of culture proposed by Edgar Schein. The industry literature provides a great deal of insight at the artefact and espoused value levels, although as yet it remains somewhat disorganized. There is, however, an overall lack of understanding of the assumption level of safety culture. This paper describes a possible framework for conceptualizing the assumption level, suggesting that safety culture is grounded in unconscious beliefs about the nature of the safety problem, its solution and how to organize to achieve the solution. Using this framework, the organization can begin to uncover the assumptions at play in its normal operation, decisions and events and, if necessary, engage in a process to shift them towards assumptions more supportive of a strong safety culture.

  14. The Immoral Assumption Effect: Moralization Drives Negative Trait Attributions.

    Science.gov (United States)

    Meindl, Peter; Johnson, Kate M; Graham, Jesse

    2016-04-01

    Jumping to negative conclusions about other people's traits is judged as morally bad by many people. Despite this, across six experiments (total N = 2,151), we find that multiple types of moral evaluations--even evaluations related to open-mindedness, tolerance, and compassion--play a causal role in these potentially pernicious trait assumptions. Our results also indicate that moralization affects negative-but not positive-trait assumptions, and that the effect of morality on negative assumptions cannot be explained merely by people's general (nonmoral) preferences or other factors that distinguish moral and nonmoral traits, such as controllability or desirability. Together, these results suggest that one of the more destructive human tendencies--making negative assumptions about others--can be caused by the better angels of our nature. © 2016 by the Society for Personality and Social Psychology, Inc.

    Bosse, Tibor; Jonker, Catholijn M; Treur, Jan

    2006-01-02

    This article introduces a novel approach for the analysis of the dynamics of reasoning processes and explores its applicability for the reasoning pattern called reasoning by assumption. More specifically, for a case study in the domain of a Master Mind game, it is shown how empirical human reasoning traces can be formalized and automatically analyzed against dynamic properties they fulfill. To this end, for the pattern of reasoning by assumption a variety of dynamic properties have been specified, some of which are considered characteristic for the reasoning pattern, whereas some other properties can be used to discriminate among different approaches to the reasoning. These properties have been automatically checked for the traces acquired in experiments undertaken. The approach turned out to be beneficial from two perspectives. First, checking characteristic properties contributes to the empirical validation of a theory on reasoning by assumption. Second, checking discriminating properties allows the analyst to identify different classes of human reasoners. 2006 Lawrence Erlbaum Associates, Inc.

    The stable model semantics has become a dominating approach to complete the knowledge provided by a logic program by means of the Closed World Assumption (CWA). The CWA asserts that any atom whose truth-value cannot be inferred from the facts and rules is supposed to be false. This assumption is orthogonal to the so-called the Open World Assumption (OWA), which asserts that every such atom's truth is supposed to be unknown. The topic of this paper is to be more fine-grained. Indeed, the objec...

  2. Nudges, shoves and budges: Behavioural economic policy frameworks.

    Science.gov (United States)

    Oliver, Adam

    2018-01-01

    Behavioural economics-the study of human decision making and how it sometimes deviates systematically from the assumptions of standard economic theory-has attracted a lot of attention in the health policy discourse over recent years. Many appear to believe that behavioural economic findings can be used only to help inform policies that manipulate the choices made by citizens, ie, the so-called nudge policy. However, these findings can be used to inform several different policy frameworks, from seemingly innocuous liberty-preserving changes to the contexts people operate in, to the outlawing of certain corporate behaviours. This article depicts diagrammatically, with the aid of a "behavioural policy cube" and in relation to smoking cessation interventions, the conceptual parameters of several behavioural economic-informed policy frameworks, which could be easily extended to other areas of health, and indeed broader public, policy.

    The Baseline Values and Assumptions Document (BVAD) provides analysts, modelers, and other life support researchers with a common set of values and assumptions which can be used as a baseline in their studies. This baseline, in turn, provides a common point of origin from which many studies in the community may depart, making research results easier to compare and providing researchers with reasonable values to assume for areas outside their experience. This document identifies many specific physical quantities that define life support systems, serving as a general reference for spacecraft life support system technology developers.

    Full Text Available Subject matter of analyze in this article are legal assumptions which must be met in order to enable private company to call for additional payment. After introductory remarks discussion is focused on existence of provisions regarding additional payment in formation contract, or in shareholders meeting general resolution, as starting point for company's claim. Second assumption is concrete resolution of shareholders meeting which creates individual obligations for additional payments. Third assumption is defined as distinctness regarding sum of payment and due date. Sending of claim by relevant company body is set as fourth legal assumption for realization of company's right to claim additional payments from member of private company.

  6. Opening the Black Box: The Experiences and Lessons From the Public Hospitals Autonomy Policy in Iran.

    2015-07-01

    Policy formulation and adoption often happen in a black box. Implementation challenges affect and modify the nature of a policy. We analyzed hospitals' autonomy policy in Iran that was intended to reduce hospitals' financial burden on government and improve their efficiency. We followed a retrospective case-study methodology, involving inductive and deductive analyses of parliamentary proceedings, policy documents, gray literature, published papers and interview transcripts. We analyzed data to develop a policy map that included important dates and events leading to the policy process milestones. We identified four time-periods with distinctive features: 'moving toward the policy' (1989 - 1994), disorganized implementation' (1995 - 1997), 'continuing challenges and indecisiveness in hospitals financing' (1998 - 2003), and 'other structural and financial policies in public hospitals' (2004 to date). We found that stakeholders required different and conflicting objectives, which certainly resulted in an unsatisfactory implementation process. The policy led to long-lasting and often negative changes in the hospital sector and the entire Iranian health system. Hospital autonomy appeared to be an ill-advised policy to remedy the inefficiency problems in low socioeconomic areas of the country. The assumption that hospital autonomy reforms would necessarily result in a better health system, may be a false assumption as their success relies on many contextual, structural and policy implementation factors.

    2000-01-01

    While DNA databases may offer the opportunity to (1) assess population-based prevalence of specific genes and variants, (2) simplify the search for molecular markers, (3) improve targeted drug discovery and development for disease management, (4) refine strategies for disease prevention, and (5) provide the data necessary for evidence-based decision-making, serious scientific and social questions remain. Whether samples are identified, coded, or anonymous, biological banking raises profound ethical and legal issues pertaining to access, informed consent, privacy and confidentiality of genomic information, civil liberties, patenting, and proprietary rights. This paper provides an overview of key policy issues and questions pertaining to biological banking, with a focus on developments in specimen collection, transnational distribution, and public health and academic-industry research alliances. It highlights the challenges posed by the commercialization of genomics, and proposes the need for harmonization of biological banking policies.

  9. Changing premises -- changing policies

    International Nuclear Information System (INIS)

    Thompson, S.C.

    1994-01-01

    The assumption that cleanup is necessary at all leaking UST sites is being questioned. The concept of natural attenuation coupled with natural biological degradation is the basis for challenging the assumed necessity of cleanup. Evidence from numerous studies indicates that natural attenuation and degradation of petroleum occur over time. These studies suggest that the processes of attenuation and degradation occur at all petroleum release sites, to varying degrees, once the actual leak is stopped. Because attenuation and degradation occur, it is asserted that cleanup of petroleum contamination is not necessary if the risk of exposure to the remaining contamination is low. The question of ''how clean is clean?'', based on the assumption that cleanup is necessary at all sites, then changes to ''is cleanup necessary at this site?'' The starting assumption becomes ''cleanup may not be necessary if risk is low.'' Public acceptance of leaving contamination in place appears to be increasing. Common criticisms, such as real estate/property values, prevention incentives, and ground water as resource issues are addressed. Also offered is a suggested framework for future policy decisions focusing on the appropriate amount of information necessary to close a leaksite

  10. The effects of country-level population policy for enhancing adaptation to climate change

    2013-11-01

    The effectiveness of population policy in reducing the combined impacts of population change and climate change on water resources is explored. One no-policy scenario and two scenarios with population policy assumptions are employed in combination with water availability under the SRES scenarios A1b, B1 and A2 for the impact analysis. The population data used are from the World Bank. The river discharges per grid of horizontal resolution 0.5° are obtained from the Total Runoff Integrating Pathways (TRIP) of the University of Tokyo, Japan. Unlike the population scenarios utilized in the SRES emission scenarios and the newest representative concentration pathways, the scenarios employed in this research are based, even after 2050, on country-level rather than regional-level growth assumptions. Our analysis implies that the heterogeneous pattern of population changes across the world is the dominant driver of water stress, irrespective of future greenhouse gas emissions, with highest impacts occurring in the already water-stressed low latitudes. In 2100, Africa, Middle East and parts of Asia are under extreme water stress under all scenarios. The sensitivity analysis reveals that a small reduction in populations over the region could relieve a large number of people from high water stress, while a further increase in population from the assumed levels (SC1) might not increase the number of people under high water stress considerably. Most of the population increase towards 2100 occurs in the already water-stressed lower latitudes. Therefore, population reduction policies are recommended for this region as a method of adaptation to the future water stress conditions. Population reduction policies will facilitate more control over their future development pathways, even if these countries were not able to contribute significantly to greenhouse gas (GHG) emission cuts due to economic constraints. However, for the European region, the population living in water

    This document presents design requirements and controlled assumptions intended for use in the engineering development and testing of: 1) prototype packages for radioactive waste disposal in deep boreholes; 2) a waste package surface handling system; and 3) a subsurface system for emplacing and retrieving packages in deep boreholes. Engineering development and testing is being performed as part of the Deep Borehole Field Test (DBFT; SNL 2014a). This document presents parallel sets of requirements for a waste disposal system and for the DBFT, showing the close relationship. In addition to design, it will also inform planning for drilling, construction, and scientific characterization activities for the DBFT. The information presented here follows typical preparations for engineering design. It includes functional and operating requirements for handling and emplacement/retrieval equipment, waste package design and emplacement requirements, borehole construction requirements, sealing requirements, and performance criteria. Assumptions are included where they could impact engineering design. Design solutions are avoided in the requirements discussion. Deep Borehole Field Test Requirements and Controlled Assumptions July 21, 2015 iv ACKNOWLEDGEMENTS This set of requirements and assumptions has benefited greatly from reviews by Gordon Appel, Geoff Freeze, Kris Kuhlman, Bob MacKinnon, Steve Pye, David Sassani, Dave Sevougian, and Jiann Su.

  1. Policy of air protection in Poland

    International Nuclear Information System (INIS)

    Karaczun, Z.M.

    1995-01-01

    The changed political situation and recognition of the acute destruction of the natural environment in Poland have caused a series of actions aimed at preventing further deterioration of Polish environment. One of the most important events which took place in the last few years was the enactment by the Polish Parliament in May 1991 of the Act on the National Ecological Policy. The basic assumption of the new environmental policy is a declaration that sustainable development will in future direct economic development in Poland. The aim of the presented paper is to introduce existing policy of air protection and instruments which have been implemented to protect the air. Special attention is paid to legislation instruments, introduction and enforcement of proper economic mechanisms strengthening air protection and foreign policy aiming at increasing foreign assistance for this objective. Pollutants involved include sulfur dioxide, nitrogen oxides, carbon dioxide and particulates from industry and coal-fired power plants. 9 refs

  4. Policy modeling for energy efficiency improvement in US industry

    International Nuclear Information System (INIS)

    Worrell, Ernst; Price, Lynn; Ruth, Michael

    2001-01-01

    We are at the beginning of a process of evaluating and modeling the contribution of policies to improve energy efficiency. Three recent policy studies trying to assess the impact of energy efficiency policies in the United States are reviewed. The studies represent an important step in the analysis of climate change mitigation strategies. All studies model the estimated policy impact, rather than the policy itself. Often the policy impacts are based on assumptions, as the effects of a policy are not certain. Most models only incorporate economic (or price) tools, which recent studies have proven to be insufficient to estimate the impacts, costs and benefits of mitigation strategies. The reviewed studies are a first effort to capture the effects of non-price policies. The studies contribute to a better understanding of the role of policies in improving energy efficiency and mitigating climate change. All policy scenarios results in substantial energy savings compared to the baseline scenario used, as well as substantial net benefits to the U.S. economy

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available From the on-line point, we consider the hospital’s medical examination appointment problem with hierarchical machines. This approach eliminates the need for both demand forecasts and a risk-neutrality assumption. Due to different unit revenue, uncertain demand, and arrival of patients, we design on-line booking policies for two kinds of different situations from the perspective of on-line policy and competitive analysis. After that, we prove the optimal competitive ratios. Through numerical examples, we compare advantages and disadvantages between on-line policies and traditional policies, finding that there is different superiority for these two policies under different arrival sequences.

  7. Data Policy

    Directory of Open Access Journals (Sweden)

    Mark A Parsons

    2013-07-01

    Full Text Available The first purpose of data policy should be to serve the objectives of the organization or project sponsoring the collection of the data. With research data, data policy should also serve the broader goals of advancing scientific and scholarly inquiry and society at large. This is especially true with government-funded data, which likely comprise the vast majority of research data. Data policy should address multiple issues, depending on the nature and objectives of the data. These issues include data access requirements, data preservation and stewardship requirements, standards and compliance mechanisms, data security issues, privacy and ethical concerns, and potentially even specific collection protocols and defined data flows. The specifics of different policies can vary dramatically, but all data policies need to address data access and preservation. Research data gain value with use and must therefore be accessible and preserved for future access. This article focuses on data access. While policy might address multiple issues, at a first level it must address where the data stand on what Lyon (2009 calls the continuum of openness. Making data as openly accessible as possible provides the greatest societal benefit, and a central purpose of data policy is to work toward ethically open data access. An open data regime not only maximizes the benefit of the data, it also simplifies most of the other issues around effective research data stewardship and infrastructure development.

  10. Politics and economics in collective action: an ethnographic critique of dichotomic premisses

    Directory of Open Access Journals (Sweden)

    Julieta Quirós

    2008-01-01

    Full Text Available Distancing itself from the formal models that have served as an axis for studies of collective action and social movements, this article seeks to reinstate the lived dimension of political engagement. Basing itself on the ethnographic analysis of a set of neighbourhoods in Greater Buenos Aires, it explores the multiple and heterogeneous ways in which people become involved in the so-called movimentos piqueteros. It indicates that these experiences become intelligible through their inscription in a wider plot of relations and possibilities. Starting from a figurational perspective, the text discusses some of the assumptions of the literature on piquetero organization, in particular, and social movements more generally; it questions that dichotomy between material reason and politico-moral reason through which the question of the motivations of collective action have been addressed; it is mistrustful of a rigid opposition between the State and social movements, pointing to the creative - and not merely co-optive - character of state policies; and, finally, it proposes to sociologize the locus of the "the pleasure of doing" in the origin and continuity of political engagement.

  13. Incorporating assumption deviation risk in quantitative risk assessments: A semi-quantitative approach

    International Nuclear Information System (INIS)

    Khorsandi, Jahon; Aven, Terje

    2017-01-01

    Quantitative risk assessments (QRAs) of complex engineering systems are based on numerous assumptions and expert judgments, as there is limited information available for supporting the analysis. In addition to sensitivity analyses, the concept of assumption deviation risk has been suggested as a means for explicitly considering the risk related to inaccuracies and deviations in the assumptions, which can significantly impact the results of the QRAs. However, challenges remain for its practical implementation, considering the number of assumptions and magnitude of deviations to be considered. This paper presents an approach for integrating an assumption deviation risk analysis as part of QRAs. The approach begins with identifying the safety objectives for which the QRA aims to support, and then identifies critical assumptions with respect to ensuring the objectives are met. Key issues addressed include the deviations required to violate the safety objectives, the uncertainties related to the occurrence of such events, and the strength of knowledge supporting the assessments. Three levels of assumptions are considered, which include assumptions related to the system's structural and operational characteristics, the effectiveness of the established barriers, as well as the consequence analysis process. The approach is illustrated for the case of an offshore installation. - Highlights: • An approach for assessing the risk of deviations in QRA assumptions is presented. • Critical deviations and uncertainties related to their occurrence are addressed. • The analysis promotes critical thinking about the foundation and results of QRAs. • The approach is illustrated for the case of an offshore installation.

    Hershenov, David B; Delaney, James J

    2010-08-01

    There remains a need to properly analyze the metaphysical assumptions underlying two organ procurement policies: presumed consent and organ sales. Our contention is that if one correctly understands the metaphysics of both the human body and material property, then it will turn out that while organ sales are illiberal, presumed consent is not. What we mean by illiberal includes violating rights of bodily integrity, property, or autonomy, as well as arguing for or against a policy in a manner that runs afoul of Rawlsian public reason.

    The article outlines some basic assumptions of the new price system and major elements of the latest proposition for the changes and supplements to the Tariff system for Electricity Sale in the Republic of Croatia, including the analysis of those elements which brought about the present unfavourable and non-productive relations within the electric power system. The paper proposes measures and actions which should by means of a price system and tariff policy improve the present unfavourable relations and their consequences and achieve a desirable consumption structure and characteristics, resulting in rational management and effective power supply-economy relationships within the electric power system as a subsystem of the power supply sector.

  20. Foreign Policy Involvement Matters: Towards an Analytical Framework Examining the Role of the Media in the Making of Foreign Policy

    Directory of Open Access Journals (Sweden)

    Kerstin Schulz

    2013-05-01

    Full Text Available Foreign policy processes have long played a minor role in the study of political communication. There is a broad consensus that the media is the central mediating actor and primary conduit between political decision-makers and the public. However, the media’s influence on foreign policy remains contingent across various processes and phases of foreign policy making; it is dynamic and multi-directional. Considering that the public sphere is essential for the legitimacy of foreign policy making, there is a demand for further research on the media’s performance in the making of foreign policy. Based on secondary research, this paper proposes an analytical framework for the systematic analysis of media–foreign policy relations by integrating foreign-policy context conditions as a research variable. The framework is based on the assumption that the role of the media varies across diverse foreign policy contexts depending on the intensity of governmental involvement in foreign affairs. The intensity is distinguished according to three dimensions: no involvement, indirect involvement and direct involvement. Finally, a case study is suggested in order to demonstrate the framework’s explanatory power: the German media coverage of Russia.

  3. Questioning Engelhardt's assumptions in Bioethics and Secular Humanism.

    Science.gov (United States)

    Ahmadi Nasab Emran, Shahram

    2016-06-01

    In Bioethics and Secular Humanism: The Search for a Common Morality, Tristram Engelhardt examines various possibilities of finding common ground for moral discourse among people from different traditions and concludes their futility. In this paper I will argue that many of the assumptions on which Engelhardt bases his conclusion about the impossibility of a content-full secular bioethics are problematic. By starting with the notion of moral strangers, there is no possibility, by definition, for a content-full moral discourse among moral strangers. It means that there is circularity in starting the inquiry with a definition of moral strangers, which implies that they do not share enough moral background or commitment to an authority to allow for reaching a moral agreement, and concluding that content-full morality is impossible among moral strangers. I argue that assuming traditions as solid and immutable structures that insulate people across their boundaries is problematic. Another questionable assumption in Engelhardt's work is the idea that religious and philosophical traditions provide content-full moralities. As the cardinal assumption in Engelhardt's review of the various alternatives for a content-full moral discourse among moral strangers, I analyze his foundationalist account of moral reasoning and knowledge and indicate the possibility of other ways of moral knowledge, besides the foundationalist one. Then, I examine Engelhardt's view concerning the futility of attempts at justifying a content-full secular bioethics, and indicate how the assumptions have shaped Engelhardt's critique of the alternatives for the possibility of content-full secular bioethics.

  4. Development of AIM for analysing policy options to reduce greenhouse gas emissions

    International Nuclear Information System (INIS)

    Kainuma, M.; Morita, T.; Matsuoka, Y.

    1999-01-01

    AIM (Asian-Pacific Integrated Model) has been developed for predicting greenhouse gas emissions and evaluating policy measures to reduce them. Two socio-economic scenarios were assumed and CO 2 emissions were predicted based on these scenarios and policy intervention assumptions. It is found that mitigating CO 2 emissions without scaling back productive activities or standards of living in Japan is possible. However, if one relies on the market mechanism alone, it cannot be done. The analysis has shown that it is essential to introduce new policies and measures such as carbon tax and subsidies. (author)

  6. Respondent-Driven Sampling – Testing Assumptions: Sampling with Replacement

    Directory of Open Access Journals (Sweden)

    Barash Vladimir D.

    2016-03-01

    Full Text Available Classical Respondent-Driven Sampling (RDS estimators are based on a Markov Process model in which sampling occurs with replacement. Given that respondents generally cannot be interviewed more than once, this assumption is counterfactual. We join recent work by Gile and Handcock in exploring the implications of the sampling-with-replacement assumption for bias of RDS estimators. We differ from previous studies in examining a wider range of sampling fractions and in using not only simulations but also formal proofs. One key finding is that RDS estimates are surprisingly stable even in the presence of substantial sampling fractions. Our analyses show that the sampling-with-replacement assumption is a minor contributor to bias for sampling fractions under 40%, and bias is negligible for the 20% or smaller sampling fractions typical of field applications of RDS.

  12. Regression assumptions in clinical psychology research practice-a systematic review of common misconceptions.

    Science.gov (United States)

    Ernst, Anja F; Albers, Casper J

    2017-01-01

    Misconceptions about the assumptions behind the standard linear regression model are widespread and dangerous. These lead to using linear regression when inappropriate, and to employing alternative procedures with less statistical power when unnecessary. Our systematic literature review investigated employment and reporting of assumption checks in twelve clinical psychology journals. Findings indicate that normality of the variables themselves, rather than of the errors, was wrongfully held for a necessary assumption in 4% of papers that use regression. Furthermore, 92% of all papers using linear regression were unclear about their assumption checks, violating APA-recommendations. This paper appeals for a heightened awareness for and increased transparency in the reporting of statistical assumption checking.

  14. Unrealistic Assumptions in Economics: an Analysis under the Logic of Socioeconomic Processes

    Directory of Open Access Journals (Sweden)

    Leonardo Ivarola

    2014-11-01

    Full Text Available The realism of assumptions is an ongoing debate within the philosophy of economics. One of the most referenced papers in this matter belongs to Milton Friedman. He defends the use of unrealistic assumptions, not only because of a pragmatic issue, but also the intrinsic difficulties of determining the extent of realism. On the other hand, realists have criticized (and still do today the use of unrealistic assumptions - such as the assumption of rational choice, perfect information, homogeneous goods, etc. However, they did not accompany their statements with a proper epistemological argument that supports their positions. In this work it is expected to show that the realism of (a particular sort of assumptions is clearly relevant when examining economic models, since the system under study (the real economies is not compatible with logic of invariance and of mechanisms, but with the logic of possibility trees. Because of this, models will not function as tools for predicting outcomes, but as representations of alternative scenarios, whose similarity to the real world will be examined in terms of the verisimilitude of a class of model assumptions

  17. Viewpoint – The Next Nexus? Environmental Ethics, Water Policies, and Climate Change

    Directory of Open Access Journals (Sweden)

    David Groenfeldt

    2010-10-01

    Full Text Available Water policies are based on ethical assumptions, and efforts to promote more sustainable policies need to address those underlying values. The history of water policies from 'command-and-control' to more ecological approaches reveals an ethical evolution, but adaptation to climate change will require further ethical shifts. The case of the Santa Fe river in New Mexico (USA illustrates how values that go unrecognised interfere with sustainable management. Exploring the underlying value dynamics is an essential step in the policy reform process and takes on added urgency in the face of climate change and the need to formulate adaptive water strategies. Bringing the topic of values and ethics into the water policy discourse can help clarify management goals and promote more sustainable practices.

  1. Evolution of Requirements and Assumptions for Future Exploration Missions

    Science.gov (United States)

    Anderson, Molly; Sargusingh, Miriam; Perry, Jay

    2017-01-01

    NASA programs are maturing technologies, systems, and architectures to enabling future exploration missions. To increase fidelity as technologies mature, developers must make assumptions that represent the requirements of a future program. Multiple efforts have begun to define these requirements, including team internal assumptions, planning system integration for early demonstrations, and discussions between international partners planning future collaborations. For many detailed life support system requirements, existing NASA documents set limits of acceptable values, but a future vehicle may be constrained in other ways, and select a limited range of conditions. Other requirements are effectively set by interfaces or operations, and may be different for the same technology depending on whether the hard-ware is a demonstration system on the International Space Station, or a critical component of a future vehicle. This paper highlights key assumptions representing potential life support requirements and explanations of the driving scenarios, constraints, or other issues that drive them.

  2. The Avalanche Hypothesis and Compression of Morbidity: Testing Assumptions through Cohort-Sequential Analysis.

    Directory of Open Access Journals (Sweden)

    Jordan Silberman

    Full Text Available The compression of morbidity model posits a breakpoint in the adult lifespan that separates an initial period of relative health from a subsequent period of ever increasing morbidity. Researchers often assume that such a breakpoint exists; however, this assumption is hitherto untested.To test the assumption that a breakpoint exists--which we term a morbidity tipping point--separating a period of relative health from a subsequent deterioration in health status. An analogous tipping point for healthcare costs was also investigated.Four years of adults' (N = 55,550 morbidity and costs data were retrospectively analyzed. Data were collected in Pittsburgh, PA between 2006 and 2009; analyses were performed in Rochester, NY and Ann Arbor, MI in 2012 and 2013. Cohort-sequential and hockey stick regression models were used to characterize long-term trajectories and tipping points, respectively, for both morbidity and costs.Morbidity increased exponentially with age (P<.001. A morbidity tipping point was observed at age 45.5 (95% CI, 41.3-49.7. An exponential trajectory was also observed for costs (P<.001, with a costs tipping point occurring at age 39.5 (95% CI, 32.4-46.6. Following their respective tipping points, both morbidity and costs increased substantially (Ps<.001.Findings support the existence of a morbidity tipping point, confirming an important but untested assumption. This tipping point, however, may occur earlier in the lifespan than is widely assumed. An "avalanche of morbidity" occurred after the morbidity tipping point-an ever increasing rate of morbidity progression. For costs, an analogous tipping point and "avalanche" were observed. The time point at which costs began to increase substantially occurred approximately 6 years before health status began to deteriorate.

  10. The Emperors sham - wrong assumption that sham needling is sham.

    Science.gov (United States)

    Lundeberg, Thomas; Lund, Iréne; Näslund, Jan; Thomas, Moolamanil

    2008-12-01

    During the last five years a large number of randomised controlled clinical trials (RCTs) have been published on the efficacy of acupuncture in different conditions. In most of these studies verum is compared with sham acupuncture. In general both verum and sham have been found to be effective, and often with little reported difference in outcome. This has repeatedly led to the conclusion that acupuncture is no more effective than placebo treatment. However, this conclusion is based on the assumption that sham acupuncture is inert. Since sham acupuncture evidently is merely another form of acupuncture from the physiological perspective, the assumption that sham is sham is incorrect and conclusions based on this assumption are therefore invalid. Clinical guidelines based on such conclusions may therefore exclude suffering patients from valuable treatments.

    RNA-Seq is a widely used method for studying the behavior of genes under different biological conditions. An essential step in an RNA-Seq study is normalization, in which raw data are adjusted to account for factors that prevent direct comparison of expression measures. Errors in normalization can have a significant impact on downstream analysis, such as inflated false positives in differential expression analysis. An underemphasized feature of normalization is the assumptions on which the methods rely and how the validity of these assumptions can have a substantial impact on the performance of the methods. In this article, we explain how assumptions provide the link between raw RNA-Seq read counts and meaningful measures of gene expression. We examine normalization methods from the perspective of their assumptions, as an understanding of methodological assumptions is necessary for choosing methods appropriate for the data at hand. Furthermore, we discuss why normalization methods perform poorly when their assumptions are violated and how this causes problems in subsequent analysis. To analyze a biological experiment, researchers must select a normalization method with assumptions that are met and that produces a meaningful measure of expression for the given experiment. © The Author 2017.

  17. Social support, world assumptions, and exposure as predictors of anxiety and quality of life following a mass trauma.

    Science.gov (United States)

    Grills-Taquechel, Amie E; Littleton, Heather L; Axsom, Danny

    2011-05-01

    This study examined the influence of a mass trauma (the Virginia Tech campus shootings) on anxiety symptoms and quality of life, as well as the potential vulnerability/protective roles of world assumptions and social support. Pre-trauma adjustment data, collected in the six months prior to the shooting, was examined along with two-month post-shooting data in a sample of 298 female students enrolled at the university at the time of the shootings. Linear regression analyses revealed consistent predictive roles for world assumptions pertaining to control and self-worth as well as family support. In addition, for those more severely exposed to the shooting, greater belief in a lack of control over outcomes appeared to increase vulnerability for post-trauma physiological and emotional anxiety symptoms. Implications of the results for research and intervention following mass trauma are discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

  18. The global climate Policy Evaluation Framework

    International Nuclear Information System (INIS)

    Cohan, D.; Stafford, R.K.; Scheraga, J.D.; Herrod, S.

    1994-01-01

    The Policy Evaluation Framework (PEF) is a decision analysis tool that enables decision makers to continuously formulate policies that take into account the existing uncertainties, and to refine policies as new scientific information is developed. PEF integrates deterministic parametric models of physical, biological, and economic systems with a flexible decision tree system. The deterministic models represent greenhouse gas emissions, atmospheric accumulation of these gases, global and regional climate changes, ecosystem impacts, economic impacts, and mitigation and adaptation options, The decision tree system captures the key scientific and economic uncertainties, and reflects the wide range of possible outcomes of alternative policy actions. The framework contains considerable flexibility to allow a wide range of scientific and economic assumptions or scenarios to be represented and explored. A key feature of PEF is its capability to address both mitigation policies and investments in anticipatory adaptation to protect ecological and economic systems, as well as interactions among such options. PEF's time structure allows issues related to the timing and flexibility of alternatives to be evaluated, while the decision tree structure facilitates examining questions involving the value of information, contingent actions, and probabilistic representations. This paper is intended to introduce PEF to the global climate policy community. The paper provides an overview of the structure, modules, and capabilities of PEF, and discusses selected results from an initial set of illustrative applications

  1. Testing the assumptions behind emissions trading in non-market goods: the RECLAIM program in Southern California

    International Nuclear Information System (INIS)

    Lejano, Raul P.; Hirose, Rei

    2005-01-01

    Emissions trading is, essentially, a policy instrument that is designed to simulate a market for an otherwise public good. Conceptually, its justification hinges on a number of key assumptions, namely the negligibility of local impacts, the ability to separate and commodify the good in question, and characteristics of a well-functioning market. The authors examine the performance of RECLAIM, a NO x emissions trading program in Southern California, USA, and illustrate how to test these assumptions. There is some evidence that the trading of NO x generates new externalities, such as the possibility that other air pollutants, e.g. volatile organics, are essentially traded along with it. Moreover, the RECLAIM program has recently begun to experience difficulties due to the fact that the market is relatively thin. This analysis provides ways to assess more deeply and reform these trading regimes, including opening up RECLAIM to public review. The case study speaks to a wider arena, as emissions trading is presently being considered in other parts of the world to address issues ranging from acid rain to non-point source pollution to greenhouse gases. The analytic approach, illustrated herein, is a general one that has a wider applicability than the particular case of NO x trading. It is hoped that this kind of critical inquiry can lead to a more careful deliberation of the merits and challenges of emissions trading

  4. Stringent Mitigation Policy Implied By Temperature Impacts on Economic Growth

    Science.gov (United States)

    Moore, F.; Turner, D.

    2014-12-01

    Integrated assessment models (IAMs) compare the costs of greenhouse gas mitigation with damages from climate change in order to evaluate the social welfare implications of climate policy proposals and inform optimal emissions reduction trajectories. However, these models have been criticized for lacking a strong empirical basis for their damage functions, which do little to alter assumptions of sustained GDP growth, even under extreme temperature scenarios. We implement empirical estimates of temperature effects on GDP growth-rates in the Dynamic Integrated Climate and Economy (DICE) model via two pathways, total factor productivity (TFP) growth and capital depreciation. Even under optimistic adaptation assumptions, this damage specification implies that optimal climate policy involves the elimination of emissions in the near future, the stabilization of global temperature change below 2°C, and a social cost of carbon (SCC) an order of magnitude larger than previous estimates. A sensitivity analysis shows that the magnitude of growth effects, the rate of adaptation, and the dynamic interaction between damages from warming and GDP are three critical uncertainties and an important focus for future research.

  5. On the Commons and Climate Change: Collective Action and GHG Mitigation - Working Paper No. 2012-13

    International Nuclear Information System (INIS)

    Cochran, Ian

    2012-07-01

    Reducing greenhouse-gas (GHG) emissions from anthropogenic activity may be one of the greatest collective-action problems faced by humanity. This poses challenges not only in terms of the institutional configurations to support coordinated governance processes, but equally the information tools and expertise necessary to link GHG mitigation with other policy priorities. This paper theoretically explores how the adoption of a modified theory of collective action based upon a behavioral theory of the individual allows for a re-framing of the climate-change policy challenge. As such, it appears important to develop a context within which collective action becomes possible where success is no longer solely tied to incentives, but equally to the provision of information, learning, and interaction between stakeholders while simultaneously fostering trust and reciprocity among actors. At all levels of government, information plays a key role to both inform and to facilitate communication, as well as to identify and develop the necessary actions and investments and to track changes in conditions. In the case of climate change, greenhouse-gas inventories and other informational tools are necessary components to track an a priori intangible emission. As such, it is key to analyze the legitimacy, credibility and saliency of information and expertise integrated into the decision-making process. Further, it is important to recognize that the construction of indicators and other information tools is not apolitical, but rather the product of a number of assumptions, interests and decisions concerning what is included and what is excluded shaped by the involved actors.

    Full Text Available Traditional activities based on sea resources (maritime transport, shipyards, fishery always played the key role in increasing production possibilities of the economies with the access to the sea. The development of technique and technology distinctly contributed to broadening the horizons and diversification of activities based on exploitation of maritime basins. Despite the positive results connected with greater and more intense exploration of seas resources, there also appeared the negative effects. First and foremost, they are connected with degradation of the natural environment and growing conflicts of interests of different groups of the basins users. The issue of split entitlement to use seas resources was brought to the world forum in 1982 by enacting the United Nations Convention on the Law of the Sea (UNCLOS. The European Commission, having contucted consultations on a large scale, accepted the Integrated Maritime Policy of the European Union (IMP EU. It was based on the assumption, that all maritime activities are interconnected and that is why they should be performed in a coordinated manner to achive the established goals. The Integrated Maritime Policy created the framework, in which the member states were to find appropiate solutions to their economy specificity, inter alia – the maritime economy. In the paper, the results of the research of maritime policies of two countries - Poland and Croatia are presented. The goal of the research is to check how far the policies of these two countries are coherent with each other and with the assumptions of the IMP. In the research the deductive method was used - it was based at conclusions from the comparative analysis. The surveys were conducted on the basis of the EU, Polish and Croatian strategic documents.

  7. Determining Bounds on Assumption Errors in Operational Analysis

    Directory of Open Access Journals (Sweden)

    Neal M. Bengtson

    2014-01-01

    Full Text Available The technique of operational analysis (OA is used in the study of systems performance, mainly for estimating mean values of various measures of interest, such as, number of jobs at a device and response times. The basic principles of operational analysis allow errors in assumptions to be quantified over a time period. The assumptions which are used to derive the operational analysis relationships are studied. Using Karush-Kuhn-Tucker (KKT conditions bounds on error measures of these OA relationships are found. Examples of these bounds are used for representative performance measures to show limits on the difference between true performance values and those estimated by operational analysis relationships. A technique for finding tolerance limits on the bounds is demonstrated with a simulation example.

  8. Persistent misunderstandings about evidence-based (sorry: informed!) policy-making.

    Bédard, Pierre-Olivier; Ouimet, Mathieu

    2016-01-01

    The field of research on knowledge mobilization and evidence-informed policy-making has seen enduring debates related to various fundamental assumptions such as the definition of 'evidence', the relative validity of various research methods, the actual role of evidence to inform policy-making, etc. In many cases, these discussions serve a useful purpose, but they also stem from serious disagreement on methodological and epistemological issues. This essay reviews the rationale for evidence-informed policy-making by examining some of the common claims made about the aims and practices of this perspective on public policy. Supplementing the existing justifications for evidence-based policy making, we argue in favor of a greater inclusion of research evidence in the policy process but in a structured fashion, based on methodological considerations. In this respect, we present an overview of the intricate relation between policy questions and appropriate research designs. By closely examining the relation between research questions and research designs, we claim that the usual points of disagreement are mitigated. For instance, when focusing on the variety of research designs that can answer a range of policy questions, the common critical claim about 'RCT-based policy-making' seems to lose some, if not all of its grip.

    Current healthcare systems have extended the evidence-based medicine (EBM) approach to health policy and delivery decisions, such as access-to-care, healthcare funding and health program continuance, through attempts to integrate valid and reliable evidence into the decision making process. These policy decisions have major impacts on society and have high personal and financial costs associated with those decisions. Decision models such as these function under a shared assumption of rational choice and utility maximization in the decision-making process. We contend that health policy decision makers are generally unable to attain the basic goals of evidence-based decision making (EBDM) and evidence-based policy making (EBPM) because humans make decisions with their naturally limited, faulty, and biased decision-making processes. A cognitive information processing framework is presented to support this argument, and subtle cognitive processing mechanisms are introduced to support the focal thesis: health policy makers' decisions are influenced by the subjective manner in which they individually process decision-relevant information rather than on the objective merits of the evidence alone. As such, subsequent health policy decisions do not necessarily achieve the goals of evidence-based policy making, such as maximizing health outcomes for society based on valid and reliable research evidence. In this era of increasing adoption of evidence-based healthcare models, the rational choice, utility maximizing assumptions in EBDM and EBPM, must be critically evaluated to ensure effective and high-quality health policy decisions. The cognitive information processing framework presented here will aid health policy decision makers by identifying how their decisions might be subtly influenced by non-rational factors.

    In early 2012, the National Institute for Health Research (NIHR) leadership programme was re-commissioned for a further three years following an evaluation by RAND Europe. During this new phase of the programme, we conducted a real-time evaluation, the aim of which was to allow for reflection on and adjustment of the programme on an on-going basis as events unfold. This approach also allowed for participants on the programme to contribute to and positively engage in the evaluation. The study aimed to understand the outputs and impacts from the programme, and to test the underlying assumptions behind the NIHR Leadership Programme as a science policy intervention. Evidence on outputs and impacts of the programme were collected around the motivations and expectations of participants, programme design and individual-, institutional- and system-level impacts.

    Hazim Adnan Hashim

    2016-09-01

    Full Text Available The present study addresses effects of traumatic events such as the September 11 attacks on victims’ fundamental assumptions. These beliefs or assumptions provide individuals with expectations about the world and their sense of self-worth. Thus, they ground people’s sense of security, stability, and orientation. The September 11 terrorist attacks in the U.S.A. were very tragic for Americans because this fundamentally changed their understandings about many aspects in life. The attacks led many individuals to build new kind of beliefs and assumptions about themselves and the world. Many writers have written about the human ordeals that followed this incident. Don DeLillo’s Falling Man reflects the traumatic repercussions of this disaster on Americans’ fundamental assumptions. The objective of this study is to examine the novel from the traumatic perspective that has afflicted the victims’ fundamental understandings of the world and the self. Individuals’ fundamental understandings could be changed or modified due to exposure to certain types of events like war, terrorism, political violence or even the sense of alienation. The Assumptive World theory of Ronnie Janoff-Bulman will be used as a framework to study the traumatic experience of the characters in Falling Man. The significance of the study lies in providing a new perception to the field of trauma that can help trauma victims to adopt alternative assumptions or reshape their previous ones to heal from traumatic effects.

  20. Greenhouse gas emissions trading and complementary policies. Developing a smart mix for ambitious climate policies

    Energy Technology Data Exchange (ETDEWEB)

    Matthes, Felix C.

    2010-06-15

    A debate has - most notably as a result of the introduction of fixed caps within the framework of emissions trading - been raised about the need for using additional instruments of climate and energy policy. A common line of argument is that the targets set within the emissions trading scheme are going to be met with a high degree of certainty, and flexibility among the regulated stakeholders will lead to market-based discovery processes. Additional instruments would only generate additional costs and would therefore have to be rejected. However, closer analysis of these fundamental arguments shows that they are constructed on a very high level of abstraction and sometimes rely on strongly simplifying or idealising assumptions. Their theoretical assumptions are, at least in part, very questionable and do not correspond to conditions in the real world for climate and energy policy. At the same time the debate about policy instruments cannot be held autonomously of the specific context of the problem at hand. In this sense the very extensive (complete) and above all effective decarbonisation of the economies of industrialised countries in a comparatively short time frame is the key basic condition for the analysis, assessment and design of the climate policy mix. Essentially, the question is what the best instruments are for purging the whole economic system almost entirely of CO{sub 2} emissions within a period of only forty years. The introduction of emissions trading schemes for greenhouse gases in an increasing number of OECD countries undoubtedly constitutes an important landmark of climate policy. They: - provide a high degree of certainty in terms of meeting targets; - create, on the basis of a standardised price signal, a clearing mechanism for the broad spectrum of emission reduction options close to the market, at least in the short to medium term; and - represent, by means of linking, an interesting option in terms of the globalisation of climate policy

    2006-01-01

    This paper explores the reasons why economic instruments of climate change are reluctantly applied and stresses the need for interdisciplinary research linking economic theory and empirical testing to deliberative political procedures. It is divided in three parts. The first one recalls the main issues in implementing Cost-Benefit Analysis such as information problems, uncertainties, discounting the future and irreversibilities. The second part shows how these issues can be treated in integrated assessment and techno-economic models and presents a case study, which shows that (1) The chosen scenario tends to stabilize atmospheric CO2 concentration at around 550 ppm in the long run; (2) Exclusion of possibility to trade CO2 emission permits under a cap regime would increase the cost of emission abatement for OECD countries; and (3) Combining different flexibility instruments might lead to significant gains in the overall cost of climate policy. The third part presents results of a survey conducted among the main economic and environmental associations in Switzerland. The survey reveals conflicting views on economic instruments. It shows how the social acceptability of these instruments can be improved in taking explicitly into account these opposing views of special interest groups. Therefore, policy scenarios should be selected in combining techno-economic models with empirical studies about their political and normative context

  2. Reconstructing the public in old and new governance: a Korean case of nuclear energy policy.

    Science.gov (United States)

    Kim, Hyomin

    2014-04-01

    Korean nuclear energy regulatory policies started to change from earlier exclusively technocratic policies into open dialogues after several anti-nuclear protests in the 1990s. However, technocratic policies still coexist with the new regulatory orientation towards openness, participation and institutional accountability. This paper analyzes Korean nuclear regulatory policies since approximately 2005 as a blend of old and new governance. The aim of the paper is not to decide whether new nuclear governance is deliberative or not by completely reviewing Korean nuclear policies after the 2000s. Instead, it provides an empirical account of how seemingly more participatory processes in decision-making entail new problems while they work with and reproduce social assumptions of different groups of the public.

  4. The incompressibility assumption in computational simulations of nasal airflow.

    Cal, Ismael R; Cercos-Pita, Jose Luis; Duque, Daniel

    2017-06-01

    Most of the computational works on nasal airflow up to date have assumed incompressibility, given the low Mach number of these flows. However, for high temperature gradients, the incompressibility assumption could lead to a loss of accuracy, due to the temperature dependence of air density and viscosity. In this article we aim to shed some light on the influence of this assumption in a model of calm breathing in an Asian nasal cavity, by solving the fluid flow equations in compressible and incompressible formulation for different ambient air temperatures using the OpenFOAM package. At low flow rates and warm climatological conditions, similar results were obtained from both approaches, showing that density variations need not be taken into account to obtain a good prediction of all flow features, at least for usual breathing conditions. This agrees with most of the simulations previously reported, at least as far as the incompressibility assumption is concerned. However, parameters like nasal resistance and wall shear stress distribution differ for air temperatures below [Formula: see text]C approximately. Therefore, density variations should be considered for simulations at such low temperatures.

  6. Impact of public policy uncertainty on renewable energy investment: Wind power and the production tax credit

    International Nuclear Information System (INIS)

    Barradale, Merrill Jones

    2010-01-01

    It is generally understood that the pattern of repeated expiration and short-term renewal of the federal production tax credit (PTC) causes a boom-bust cycle in wind power plant investment in the US. This on-off pattern is detrimental to the wind industry, since ramp-up and ramp-down costs are high, and players are deterred from making long-term investments. It is often assumed that the severe downturn in investment during 'off' years implies that wind power is unviable without the PTC. This assumption turns out to be unsubstantiated: this paper demonstrates that it is not the absence of the PTC that causes the investment downturn during 'off' years, but rather the uncertainty over its return. Specifically, it is the dynamic of power purchase agreement (PPA) negotiations in the face of PTC renewal uncertainty that drives investment volatility. With contract negotiations prevalent in the renewable energy industry, this finding suggests that reducing uncertainty is a crucial component of effective renewable energy policy. The PTC as currently structured is not the only means, existing or potential, for encouraging wind power investment. Using data from a survey of energy professionals, various policy instruments are compared in terms of their perceived stability for supporting long-term investment. - Research highlights: →The case of wind energy investment in the face of PTC uncertainty provides an important study in how industry structure, and in particular the process of contract negotiations, can amplify the impact of public policy uncertainty on corporate investment. →The finding that contract negotiations in the face of uncertainty are sufficient in themselves to hinder investment implies that the assumption that investment downturns reflect unfavorable economics is unfounded. This assumption falsely discourages interest and investment in wind energy. →Policy stability should be added to the list of criteria explicitly considered in designing policy

    Policy implementation remains an under researched area in most low and middle income countries and it is not surprising that several policies are implemented without a systematic follow up of why and how they are working or failing. This study is part of a larger project called Supporting Policy Engagement for Evidence-based Decisions (SPEED) for Universal Health Coverage in Uganda. It seeks to support policymakers monitor the implementation of vital programmes for the realisation of policy goals for Universal Health Coverage. A Policy Implementation Barometer (PIB) is proposed as a mechanism to provide feedback to the decision makers about the implementation of a selected set of policy programmes at various implementation levels (macro, meso and micro level). The main objective is to establish the extent of implementation of malaria, family planning and emergency obstetric care policies in Uganda and use these results to support stakeholder engagements for corrective action. This is the first PIB survey of the three planned surveys and its specific objectives include: assessment of the perceived appropriateness of implementation programmes to the identified policy problems; determination of enablers and constraints to implementation of the policies; comparison of on-line and face-to-face administration of the PIB questionnaire among target respondents; and documentation of stakeholder responses to PIB findings with regard to corrective actions for implementation. The PIB will be a descriptive and analytical study employing mixed methods in which both quantitative and qualitative data will be systematically collected and analysed. The first wave will focus on 10 districts and primary data will be collected through interviews. The study seeks to interview 570 respondents of which 120 will be selected at national level with 40 based on each of the three policy domains, 200 from 10 randomly selected districts, and 250 from 50 facilities. Half of the respondents at

    Since a decision-making by intuitive judgement under uncertain future conditions can not select an optimum alternative, reaching an agreement for alternatives between experts requires a development of several scientific opinion collection methodologies and performing these methodologies. Therefore, opinion collection for all points related to the nuclear energy, public hearing induction related researches and the acts, procedure, etc. performed in developed countries such as U.S, U.K, France, etc. are reviewed and analyzed in this research. And after the analysis of domestic spent nuclear fuel management plan, Task Force Team composed of experts in several related areas is organized to suggest strategies and directions which are necessary for making a national policy. Beside, Task Force Team selects an optimum technical alternative by the analysis and comparison in depth between these technical alternatives to establish the policy direction. They also established the procedures such as opinion collecting, etc. through policy conference and forum and suggested the technical data related nuclear policy which supports the nuclear policy conference. Results from this research are expected to decrease the trial and error that has been occurred in the present policy-making procedure such as radioactive waste repository related procedure and contribute for socio-cultural stability. Moreover, opinion collection plan for developing a nuclear policy alternative is expected to contribute for making a nuclear policy in the nuclear policy conference so that the nuclear technology will be enhanced more

    Chernov A. (Ukraine), Cogoni M. (Italy), Dziubacki D. (Poland), Bădescu A. (Romania). In this paper review of details about GPR investigation from Church of the Assumption of the Blessed Virgin Mary, which was obtained during SEG Field Camp 2016, are represented. Church was constructed from the fourteenth through the sixteenth centuries. Its rich architectural forms, embellished interior, which was ornamented by Italian stuccoists, are closely bound up with its magnificent history. According to the information about church's history, there are burials of the founder of the Chapel of the Dead Count Montani of Ołdrzychowice and several crypts under the floor of the church. Also in the 20 century, the entry point to the tunnel network was discovered below the parochial Church of the Assumption of the Blessed Virgin Mary. Moreover, it is considered that there are still could be unrevealed secrets bellow church. 70 GPR profiles were recorded with GPRs MALA 500 and 800 MHz antennas. Investigations were carried out in chaples, along and cross aisles. The surveys in the chapels were designed in a regular grid which covered the whole space on the floor. Processing of GPR profiles was done in software ReflexW. Firstly such processing tools as DC shift, move star time, gain function, background removal. To get geometry of big reflectors, which are located on the same depth with smaller reflectors (hyperbolas for targets with radius 0), parameter "radius of the target" was increased till synthetic hyperbola fitted the anomaly on the GPR profile for bigger object. As a result of processing and interpretation of the results, on radargrams collected by different antennas reflections are visible almost on the same places. On the profiles, obtained in the Chapel of the Dead strong reflections identified on the depth 0.1; 1.15 m which fit to the hyperbola for target's radius 3m and 2 m; on the depth 2.7 m there is a reflection from flat surface. On profiles gathered in St. Jacob

    2013-01-01

    The author first recalls the main events and decisions regarding the German policy from 1998 to 2011, and notably the decisions related to nuclear energy. He gives the main data of the German energy system (production capacity, production of the different primary sources) and indicates the main characteristics and assumptions of the 2011 turnaround (decision of shutting down 17 nuclear plants by 2022, objectives in terms of renewable energy production and share, of electricity consumption, and of greenhouse gas emission). The author then presents how the law on renewable energies (EEG) operates, indicates energy prices in Germany for individuals and industries and CO 2 emissions per electric sector, and compares them with the French ones. He outlines the need of construction of new energy transport lines, and identifies and comments other implications of the intermittent character of renewable energies in terms of electricity market organisation, of construction of combustion-based thermal plants, and of flexibility requirements. He discusses successes and difficulties of this evolution of energy policy, and the implication of this new policy for the European Union and for border countries

  12. A POLICY MIX TO PREVENT A NON-COMMONS TRAGEDY FOR COLLECTIVE FOREST RESERVES IN AGRARIAN SETTLEMENTS IN NORTHWEST MATO GROSSO

    Directory of Open Access Journals (Sweden)

    R.B. Davenport

    Full Text Available ABSTRACT Agrarian reform settlements have recently been identified as a major contributor to ongoing deforestation in the Brazilian Amazon. Collective forest reserves were established in some settlements to thwart forest loss, but settlers usually do not recognize forest commons, opting instead for continued private accumulation through forest clearing, or a "non-commons" tragedy. Pathways toward ensuring the viability of common-pool management in settlements remain unclear. Our case study focused on two similarly sized settlements in neighboring municipalities in Northwest Mato Grosso, Brazil, each with formally designated collective forest areas. In one, deforestation shifted into the collective reserve and intensified; in the other, deforestation stabilized and the collective reserve was protected. In the latter, settlers understood their collective forest reserve as a commonly held asset, with two commercially viable settlement cooperatives involved in Brazil nut (Bertholletia excelsa extractivism and added value processing. We analyze differences between the two settlements using Elinor Ostrom's framework for analysis of socio-ecological systems, and identify the locally applied policy mix ensuring the viability of a forest commons. The study concludes that "top-down" efforts to institutionalize collective governance over remaining forests will likely fail in most settlements, without a focus on alternative livelihood opportunities synergetic with forest tenure.

    2014-03-01

    This study explores groundwater management policies and the effect of modeling assumptions on the projected performance of those policies. The study compares an optimal economic allocation for groundwater use subject to streamflow constraints, achieved by a central planner with perfect foresight, with a uniform tax on groundwater use and a uniform quota on groundwater use. The policies are compared with two modeling approaches, the Optimal Control Model (OCM) and the Multi-Agent System Simulation (MASS). The economic decision models are coupled with a physically based representation of the aquifer using a calibrated MODFLOW groundwater model. The results indicate that uniformly applied policies perform poorly when simulated with more realistic, heterogeneous, myopic, and self-interested agents. In particular, the effects of the physical heterogeneity of the basin and the agents undercut the perceived benefits of policy instruments assessed with simple, single-cell groundwater modeling. This study demonstrates the results of coupling realistic hydrogeology and human behavior models to assess groundwater management policies. The Republican River Basin, which overlies a portion of the Ogallala aquifer in the High Plains of the United States, is used as a case study for this analysis.

    2016-01-01

    Impacts of cloud overlap assumptions on radiative budgets and heating fields are explored with the aid of a cloud-resolving model (CRM), which provided cloud geometry as well as cloud micro and macro properties. Large-scale forcing data to drive the CRM are from TRMM Kwajalein Experiment and the Global Atmospheric Research Program's Atlantic Tropical Experiment field campaigns during which abundant convective systems were observed. The investigated overlap assumptions include those that were traditional and widely used in the past and the one that was recently addressed by Hogan and Illingworth (2000), in which the vertically projected cloud fraction is expressed by a linear combination of maximum and random overlap, with the weighting coefficient depending on the so-called decorrelation length Lcf. Results show that both shortwave and longwave cloud radiative forcings (SWCF/LWCF) are significantly underestimated under maximum (MO) and maximum-random (MRO) overlap assumptions, whereas remarkably overestimated under the random overlap (RO) assumption in comparison with that using CRM inherent cloud geometry. These biases can reach as high as 100 Wm- 2 for SWCF and 60 Wm- 2 for LWCF. By its very nature, the general overlap (GenO) assumption exhibits an encouraging performance on both SWCF and LWCF simulations, with the biases almost reduced by 3-fold compared with traditional overlap assumptions. The superiority of GenO assumption is also manifested in the simulation of shortwave and longwave radiative heating fields, which are either significantly overestimated or underestimated under traditional overlap assumptions. The study also pointed out the deficiency of constant assumption on Lcf in GenO assumption. Further examinations indicate that the CRM diagnostic Lcf varies among different cloud types and tends to be stratified in the vertical. The new parameterization that takes into account variation of Lcf in the vertical well reproduces such a relationship and

  16. Forecasting Value-at-Risk under Different Distributional Assumptions

    2016-01-01

    Full Text Available Financial asset returns are known to be conditionally heteroskedastic and generally non-normally distributed, fat-tailed and often skewed. These features must be taken into account to produce accurate forecasts of Value-at-Risk (VaR. We provide a comprehensive look at the problem by considering the impact that different distributional assumptions have on the accuracy of both univariate and multivariate GARCH models in out-of-sample VaR prediction. The set of analyzed distributions comprises the normal, Student, Multivariate Exponential Power and their corresponding skewed counterparts. The accuracy of the VaR forecasts is assessed by implementing standard statistical backtesting procedures used to rank the different specifications. The results show the importance of allowing for heavy-tails and skewness in the distributional assumption with the skew-Student outperforming the others across all tests and confidence levels.

    2014-05-01

    Full Text Available A main objective of European governments is to reduce the number of early retirees, either by reforming pension systems or promoting active aging in working life. The importance of formulating a coherent personnel policy for all age groups is increasingly recognized by employers. However, there is still a lack of knowledge as how to strategically cope with an aging labor force. The aim of this article is to define and discuss a number of challenges arising from workplace-related active aging policies. We in particular discuss how an emphasis on economic incentives and gains (“senior goods” may give rise to unanticipated side effects for the employers as well as the employees. The article is based on results from two recent studies: one study examining six Norwegian municipalities with seemingly good practices in work-related old age policies, and another examining such policies in eight establishments in four different industries.

    Biomass can help reduce greenhouse gas (GHG) emissions by displacing petroleum in the transportation sector, by displacing fossil-based electricity, and by sequestering atmospheric carbon. Which use mitigates the most emissions depends on market and regulatory contexts outside the scope of attributional life cycle assessments. We show that bioelectricity's advantage over liquid biofuels depends on the GHG intensity of the electricity displaced. Bioelectricity that displaces coal-fired electricity could reduce GHG emissions, but bioelectricity that displaces wind electricity could increase GHG emissions. The electricity displaced depends upon existing infrastructure and policies affecting the electric grid. These findings demonstrate how model assumptions about whether the vehicle fleet and bioenergy use are fixed or free parameters constrain the policy questions an analysis can inform. Our bioenergy life cycle assessment can inform questions about a bioenergy mandate's optimal allocation between liquid fuels and electricity generation, but questions about the optimal level of bioenergy use require analyses with different assumptions about fixed and free parameters.

  3. Social inclusion policy: Producing justice or retribution?

    Directory of Open Access Journals (Sweden)

    Kym Macfarlane

    2010-10-01

    Full Text Available The notion of social inclusion has currently gained extraordinary credence in Australia. Policy incorporating social inclusion abounds across all discipline areas with the federal government for the first time instituting a government portfolio for this area, headed by the Deputy Prime Minister. Such a move indicates the importance of managing aspects of inclusion across all sectors, in a country where diversity abounds. However, this focus on inclusion can prove highly problematic, when it becomes such an integral part of policy formulation and of the assumptions, omissions and contradictions that policy produces. This paper examines how policy discourse produces ways of thinking about inclusion/exclusion. Using three vignettes, the author applies the theories of Michel Foucault to argue that the discursive production of such inclusive policy works to simultaneously exclude by categorising particular types of individuals and families as “proper” participants in society. The author contends that understandings of propriety relating to the inclusion/exclusion binary reinscribe each other, in ways that situate particular citizens outside of possibilities for “success” in social and systemic participation. Such understanding is highlighted by a conceptual examination of the ways in which discursively produced notions of propriety become normalised.

  5. Economic efficiency of solar hot water policy in New Zealand

    International Nuclear Information System (INIS)

    Gillingham, Kenneth

    2009-01-01

    New Zealand has recently followed the path of several other countries in promoting solar hot water (SHW) systems in the effort to reduce greenhouse gas emissions, yet the economic efficiency of large-scale policies to encourage SHW remains a pressing question for policymakers. This paper develops an economic framework to examine policies to promote SHW in New Zealand, including the current information, training, and subsidy policy. The economic framework points to environmental, energy security, and average-cost electricity retail pricing market failures as motivation for SHW policy, with the global climate change externality the most important of these. The results indicate that domestic SHW systems are close to being financially attractive from a consumer perspective, but a more substantial subsidy policy would be necessary for SHW to appeal to a wider audience. Such a policy is far more likely to have positive net benefits than a policy of mandating SHW on all homes or all new homes in New Zealand, and could be justified on economic efficiency grounds under reasonable assumptions. However, this result reverses under an economy-wide carbon trading system that internalizes the environmental externality.

  6. Tax administration as health policy: hospitals, the Internal Revenue Service, and the courts.

    Science.gov (United States)

    Fox, D M; Schaffer, D C

    1991-01-01

    Since 1969 federal tax policy has permitted nonprofit hospitals to turn away indigent patients or to transfer them to public hospitals. The Internal Revenue Service made health policy, but its officials remain convinced that they were not making policy at all. Convinced that it was reasoning from legal principles, the Revenue Service accepted the hospital industry's view of the history and purpose of hospitals. The federal courts further obscured the problem. Moreover, the Revenue Service took no interest in the effects of its ruling on the services provided by tax-exempt hospitals until 1989. We describe these events and seek to explain them by linking the recent history of health policy to the assumptions that govern the making of tax policy. We conclude that the making of health policy by tax officials who are not accountable for it and who believe that they are not making policy at all is not in the public interest.

  12. Measuring Sexual Orientation: A Review and Critique of U.S. Data Collection Efforts and Implications for Health Policy.

    Science.gov (United States)

    Wolff, Margaret; Wells, Brooke; Ventura-DiPersia, Christina; Renson, Audrey; Grov, Christian

    The U.S. Department of Health and Human Services' (HHS) Healthy People 2020 goals sought to improve health outcomes among sexual minorities; HHS acknowledged that a dearth of sexual orientation items in federal and state health surveys obscured a broad understanding of sexual minority-related health disparities. The HHS 2011 data progression plan aimed to advance sexual orientation data collection efforts at the national level. Sexual orientation is a complex, multidimensional construct often composed of sexual identity, sexual attraction, and sexual behavior, thus posing challenges to its quantitative and practical measurement and analysis. In this review, we (a) present existing sexual orientation constructs; (b) evaluate current HHS sexual orientation data collection efforts; (c) review post-2011 data progression plan research on sexual minority health disparities, drawing on HHS survey data; (d) highlight the importance of and (e) identify obstacles to multidimensional sexual orientation measurement and analysis; and (f) discuss methods for multidimensional sexual orientation analysis and propose a matrix for addressing discordance/branchedness within these analyses. Multidimensional sexual orientation data collection and analysis would elucidate sexual minority-related health disparities, guide related health policies, and enhance population-based estimates of sexual minority individuals to steer health care practices.

  13. Algebraic formulation of collective models. I. The mass quadrupole collective model

    International Nuclear Information System (INIS)

    Rosensteel, G.; Rowe, D.J.

    1979-01-01

    This paper is the first in a series of three which together present a microscopic formulation of the Bohr--Mottelson (BM) collective model of the nucleus. In this article the mass quadrupole collective (MQC) model is defined and shown to be a generalization of the BM model. The MQC model eliminates the small oscillation assumption of BM and also yields the rotational and CM (3) submodels by holonomic constraints on the MQC configuration space. In addition, the MQC model is demonstrated to be an algebraic model, so that the state space of the MQC model carries an irrep of a Lie algebra of microscopic observables, the MQC algebra. An infinite class of new collective models is then given by the various inequivalent irreps of this algebra. A microscopic embedding of the BM model is achieved by decomposing the representation of the MQC algebra on many-particle state space into its irreducible components. In the second paper this decomposition is studied in detail. The third paper presents the symplectic model, which provides the realization of the collective model in the harmonic oscillator shell model

  14. Impact of one-layer assumption on diffuse reflectance spectroscopy of skin

    Science.gov (United States)

    Hennessy, Ricky; Markey, Mia K.; Tunnell, James W.

    2015-02-01

    Diffuse reflectance spectroscopy (DRS) can be used to noninvasively measure skin properties. To extract skin properties from DRS spectra, you need a model that relates the reflectance to the tissue properties. Most models are based on the assumption that skin is homogenous. In reality, skin is composed of multiple layers, and the homogeneity assumption can lead to errors. In this study, we analyze the errors caused by the homogeneity assumption. This is accomplished by creating realistic skin spectra using a computational model, then extracting properties from those spectra using a one-layer model. The extracted parameters are then compared to the parameters used to create the modeled spectra. We used a wavelength range of 400 to 750 nm and a source detector separation of 250 μm. Our results show that use of a one-layer skin model causes underestimation of hemoglobin concentration [Hb] and melanin concentration [mel]. Additionally, the magnitude of the error is dependent on epidermal thickness. The one-layer assumption also causes [Hb] and [mel] to be correlated. Oxygen saturation is overestimated when it is below 50% and underestimated when it is above 50%. We also found that the vessel radius factor used to account for pigment packaging is correlated with epidermal thickness.

    Logistic regression has increasingly become the tool of choice when analyzing data with a binary dependent variable. While resources relating to the technique are widely available, clear discussions of why logistic regression should be used in place of ordinary least squares regression are difficult to find. The current paper compares and contrasts the assumptions of ordinary least squares with those of logistic regression and explains why logistic regression's looser assumptions make it adept at handling violations of the more important assumptions in ordinary least squares.

    Effective nutrition and obesity policies that improve the food environments in which Americans live, work, and play can have positive effects on the quality of human diets. The Centers for Disease Control and Prevention's (CDC's) Nutrition and Obesity Policy Research and Evaluation Network (NOPREN) conducts transdisciplinary practice-based policy research and evaluation to foster understanding of the effectiveness of nutrition policies. The articles in this special collection bring to light a set of policies that are being used across the United States. They add to the larger picture of policies that can work together over time to improve diet and health.

    2016-01-01

    We use a mathematical programming model to examine the impacts of simultaneous implementation of two US biofuel and bioenergy policies on commodity markets and spatial distribution of future cellulosic biorefineries. The key findings based on our numerical simulation are: (1) the number and average annual production capacity of cellulosic biofuel refineries depend on the total renewable fuels mandate; (2) the mix of cellulosic biomass feedstock depends on the assumptions about the production costs of energy crops and the amount of cropland that can be used for energy crops, but regardless of the assumptions crop residues are the primary biomass source to meet the demand for biomass for biofuel production and electricity generation; and (3) the biomass production areas would surround either future cellulosic biorefineries or the existing coal-based power plants to reduce the costs of biomass transportation. These findings have important implications for biorefinery investors and provide valuable policy insights for the selection of Biomass Crop Assistance Program project areas. - Highlights: •Impacts of US biofuel and bioenergy policies are analyzed. •The number and production capacity of biorefineries depend on the biofuel policies. •Crop residues are the primary biomass source for bioenergy production. •Biomass production areas will surround cellulosic biorefineries or power plants.

    2006-01-01

    Full Text Available A general problem of this research is to identify if there is a relationship between the assumption on human nature and work (Mcgregor, Argyris, Schein, Steers and Porter and a general organizational model preference, as well as a mechanism of human resource management? This research was carried out in 2005/2006. The sample consisted of 317 subjects (197 managers, 105 highly educated subordinates and 15 entrepreneurs in 7 big enterprises in a group of small business enterprises differentiating in terms of the entrepreneur’s structure and a type of activity. A general hypothesis "that assumptions on human nature and work are statistically significant in connection to the preference approach (models, of work motivation commitment", has been confirmed. A specific hypothesis have been also confirmed: ·The assumptions on a human as a rational economic being are statistically significant in correlation with only two mechanisms of traditional models, the mechanism of method work control and the working discipline mechanism. ·Statistically significant assumptions on a human as a social being are correlated with all mechanisms of engaging employees, which belong to the model of the human relations, except the mechanism introducing the adequate type of prizes for all employees independently of working results. ·The assumptions on a human as a creative being are statistically significant, positively correlating with preference of two mechanisms belonging to the human resource model by investing into education and training and making conditions for the application of knowledge and skills. The young with assumptions on a human as a creative being prefer much broader repertoire of mechanisms belonging to the human resources model from the remaining category of subjects in the pattern. The connection between the assumption on human nature and preference models of engaging appears especially in the sub-pattern of managers, in the category of young subjects

  4. A general approach to total repair cost limit replacement policies

    Directory of Open Access Journals (Sweden)

    F. Beichelt

    2014-01-01

    Full Text Available A common replacement policy for technical systems consists in replacing a system by a new one after its economic lifetime, i.e. at that moment when its long-run maintenance cost rate is minimal. However, the strict application of the economic lifetime does not take into account the individual deviations of maintenance cost rates of single systems from the average cost development. Hence, Beichet proposed the total repair cost limit replacement policy: the system is replaced by a new one as soon as its total repair cost reaches or exceeds a given level. He modelled the repair cost development by functions of the Wiener process with drift. Here the same policy is considered under the assumption that the one-dimensional probability distribution of the process describing the repair cost development is given. In the examples analysed, applying the total repair cost limit replacement policy instead of the economic life-time leads to cost savings of between 4% and 30%. Finally, it is illustrated how to include the reliability aspect into the policy.

  5. Limiting assumptions in molecular modeling: electrostatics.

    Science.gov (United States)

    Marshall, Garland R

    2013-02-01

    Molecular mechanics attempts to represent intermolecular interactions in terms of classical physics. Initial efforts assumed a point charge located at the atom center and coulombic interactions. It is been recognized over multiple decades that simply representing electrostatics with a charge on each atom failed to reproduce the electrostatic potential surrounding a molecule as estimated by quantum mechanics. Molecular orbitals are not spherically symmetrical, an implicit assumption of monopole electrostatics. This perspective reviews recent evidence that requires use of multipole electrostatics and polarizability in molecular modeling.

  7. Temperature impacts on economic growth warrant stringent mitigation policy

    Science.gov (United States)

    Moore, Frances C.; Diaz, Delavane B.

    2015-02-01

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

    2017-06-01

    Helping scientists and engineers challenge received assumptions about how science, engineering, and society relate is a critical cornerstone for macroethics education. Scientific and engineering research are frequently framed as first steps of a value-free linear model that inexorably leads to societal benefit. Social studies of science and assessments of scientific and engineering research speak to the need for a more critical approach to the noble intentions underlying these assumptions. "Science Outside the Lab" is a program designed to help early-career scientists and engineers understand the complexities of science and engineering policy. Assessment of the program entailed a pre-, post-, and 1 year follow up survey to gauge student perspectives on relationships between science and society, as well as a pre-post concept map exercise to elicit student conceptualizations of science policy. Students leave Science Outside the Lab with greater humility about the role of scientific expertise in science and engineering policy; greater skepticism toward linear notions of scientific advances benefiting society; a deeper, more nuanced understanding of the actors involved in shaping science policy; and a continued appreciation of the contributions of science and engineering to society. The study presents an efficacious program that helps scientists and engineers make inroads into macroethical debates, reframe the ways in which they think about values of science and engineering in society, and more thoughtfully engage with critical mediators of science and society relationships: policy makers and policy processes.

  10. Validity of the mockwitness paradigm: testing the assumptions.

    Science.gov (United States)

    McQuiston, Dawn E; Malpass, Roy S

    2002-08-01

    Mockwitness identifications are used to provide a quantitative measure of lineup fairness. Some theoretical and practical assumptions of this paradigm have not been studied in terms of mockwitnesses' decision processes and procedural variation (e.g., instructions, lineup presentation method), and the current experiment was conducted to empirically evaluate these assumptions. Four hundred and eighty mockwitnesses were given physical information about a culprit, received 1 of 4 variations of lineup instructions, and were asked to identify the culprit from either a fair or unfair sequential lineup containing 1 of 2 targets. Lineup bias estimates varied as a result of lineup fairness and the target presented. Mockwitnesses generally reported that the target's physical description was their main source of identifying information. Our findings support the use of mockwitness identifications as a useful technique for sequential lineup evaluation, but only for mockwitnesses who selected only 1 lineup member. Recommendations for the use of this evaluation procedure are discussed.

  13. Projecting India's energy requirements for policy formulation

    Parikh, Kirit S.; Karandikar, Vivek; Rana, Ashish; Dani, Prasanna

    2009-01-01

    Energy policy has to have a long-term perspective. To formulate it one needs to know the contours of energy requirements and options. Different approaches have been followed in literature, each with their own problems. A top down econometric approach provides little guidance on policies, while a bottom up approval requires too much knowledge and too many assumptions. Using top-down econometric approach for aggregate overall benchmarking and a detailed activity analysis model, Integrated Energy System Model, for a few large sectors, provides a unique combination for easing the difficulties of policy formulation. The model is described in this paper. Eleven alternate scenarios are built, designed to map out extreme points of feasible options. Results show that even after employing all domestic energy resource to their full potential, there will be a continued rise of fossil fuel use, continued importance of coal, and continued rise of import dependence. Energy efficiency emerges as a major option with a potential to reduce energy requirement by as much as 17%. Scenario results point towards pushing for development of alternative sources. (author)

  14. The sufficiency assumption of the reasoned approach to action

    Directory of Open Access Journals (Sweden)

    David Trafimow

    2015-12-01

    Full Text Available The reasoned action approach to understanding and predicting behavior includes the sufficiency assumption. Although variables not included in the theory may influence behavior, these variables work through the variables in the theory. Once the reasoned action variables are included in an analysis, the inclusion of other variables will not increase the variance accounted for in behavioral intentions or behavior. Reasoned action researchers are very concerned with testing if new variables account for variance (or how much traditional variables account for variance, to see whether they are important, in general or with respect to specific behaviors under investigation. But this approach tacitly assumes that accounting for variance is highly relevant to understanding the production of variance, which is what really is at issue. Based on the variance law, I question this assumption.

    Science is all about testing the things we take for granted including some of the most fundamental aspects of how we understand our universe. Is the speed of light in a vacuum the same for all photons regardless of their energy? Is the rest mass of a photon actually zero? A series of recent studies explore the possibility of using transient astrophysical sources for tests!Explaining Different Arrival TimesArtists illustration of a gamma-ray burst, another extragalactic transient, in a star-forming region. [NASA/Swift/Mary Pat Hrybyk-Keith and John Jones]Suppose you observe a distant transient astrophysical source like a gamma-ray burst, or a flare from an active nucleus and two photons of different energies arrive at your telescope at different times. This difference in arrival times could be due to several different factors, depending on how deeply you want to question some of our fundamental assumptions about physics:Intrinsic delayThe photons may simply have been emitted at two different times by the astrophysical source.Delay due to Lorentz invariance violationPerhaps the assumption that all massless particles (even two photons with different energies) move at the exact same velocity in a vacuum is incorrect.Special-relativistic delayMaybe there is a universal speed for massless particles, but the assumption that photons have zero rest mass is wrong. This, too, would cause photon velocities to be energy-dependent.Delay due to gravitational potentialPerhaps our understanding of the gravitational potential that the photons experience as they travel is incorrect, also causing different flight times for photons of different energies. This would mean that Einsteins equivalence principle, a fundamental tenet of general relativity (GR), is incorrect.If we now turn this problem around, then by measuring the arrival time delay between photons of different energies from various astrophysical sources the further away, the better we can provide constraints on these

    Highlights: • We investigate the optimal policy mix for dealing with climate change. • We consider jointly mitigation, adaptation, and solar radiation management (SRM). • SRM can control temperature, but brings environmental side-effects. • SRM is not robust due to uncertainty in magnitude and persistency of side-effects. • Implementing SRM with wrong assumptions about side-effects largely decreases welfare. - Abstract: We investigate geoengineering as a possible substitute for mitigation and adaptation measures to address climate change. Relying on an integrated assessment model, we distinguish between the effects of solar radiation management (SRM) on atmospheric temperature levels and its side-effects on the environment. The optimal climate portfolio is a mix of mitigation, adaptation, and SRM. When accounting for uncertainty in the magnitude of SRM side-effects and their persistency over time, we show that the SRM option lacks robustness. We then analyse the welfare consequences of basing the SRM decision on wrong assumptions about its side-effects, and show that total output losses are considerable and increase with the error horizon. This reinforces the need to balance the policy portfolio in favour of mitigation

    2006-01-01

    Full Text Available What does the presence of Spaniards in international organisations signify and entail? Why, for what, and how should this be promoted? In order to answer such questions, the author analyses the meaning and implications of this presence in a globalised world in which a commitment to effective multilateralism entails a commitment to the international organisms as forums for and actors in global governance, and their presence in our societies and lives. This means both the promoting of Spanish presence in the administrations inwhich the proposals are formed which embody the general interest of the international organisations, like the multilateralisation of Spanish society. For this reason, in the framework of its multilateral policy, Spain is currently developing a policy of promoting the presence of Spaniards in international organisations in the areas of information, training, promotion and incentives, the outlines and results of which are described in this article.

    Directory of Open Access Journals (Sweden)

    Alison Moore

    2011-11-01

    Full Text Available This article considers the broad politics of the creation and maintenance of two large erotica collections in European national libraries across their histories and in relation to definitions of censorship and obscenity. It also examines the popular and intellectual discourses that have surrounded the Collection de l’Enfer and the Private Case of the British Library, and imbued them with a particular cultural mystique as repositories of secret, hidden and privileged erotic knowledge.  Censorship and repression of sexuality cannot account for the policies of these libraries which have policed public morals through their restricted access conditions, even as the works they deemed obscene were published without any legal sanction. By classing their contents into a discreet category, these collections have helped to frame erotic signification as a separate body of meaning. In France the notion of the Enfer’s place within national patrimony has particularly abetted the discourses of mystique and allure around it. In Britain, the bibliographers who have discussed the Private Case have done so through assumptions of masculine heterosexual privilege and normativity.

  6. Detecting and accounting for violations of the constancy assumption in non-inferiority clinical trials.

    Science.gov (United States)

    Koopmeiners, Joseph S; Hobbs, Brian P

    2018-05-01

    Randomized, placebo-controlled clinical trials are the gold standard for evaluating a novel therapeutic agent. In some instances, it may not be considered ethical or desirable to complete a placebo-controlled clinical trial and, instead, the placebo is replaced by an active comparator with the objective of showing either superiority or non-inferiority to the active comparator. In a non-inferiority trial, the experimental treatment is considered non-inferior if it retains a pre-specified proportion of the effect of the active comparator as represented by the non-inferiority margin. A key assumption required for valid inference in the non-inferiority setting is the constancy assumption, which requires that the effect of the active comparator in the non-inferiority trial is consistent with the effect that was observed in previous trials. It has been shown that violations of the constancy assumption can result in a dramatic increase in the rate of incorrectly concluding non-inferiority in the presence of ineffective or even harmful treatment. In this paper, we illustrate how Bayesian hierarchical modeling can be used to facilitate multi-source smoothing of the data from the current trial with the data from historical studies, enabling direct probabilistic evaluation of the constancy assumption. We then show how this result can be used to adapt the non-inferiority margin when the constancy assumption is violated and present simulation results illustrating that our method controls the type-I error rate when the constancy assumption is violated, while retaining the power of the standard approach when the constancy assumption holds. We illustrate our adaptive procedure using a non-inferiority trial of raltegravir, an antiretroviral drug for the treatment of HIV.

For discovering the physical universe additive measures such as mass, force, energy, temperature, etc. are used. Economics and conventional business intelligence try to continue this empiricist tradition and in statistical and econometric tools they appeal only to the measurable aspects of reality.

  8. Assumption-versus data-based approaches to summarizing species' ranges.

    Science.gov (United States)

    Peterson, A Townsend; Navarro-Sigüenza, Adolfo G; Gordillo, Alejandro

    2018-06-01

    For conservation decision making, species' geographic distributions are mapped using various approaches. Some such efforts have downscaled versions of coarse-resolution extent-of-occurrence maps to fine resolutions for conservation planning. We examined the quality of the extent-of-occurrence maps as range summaries and the utility of refining those maps into fine-resolution distributional hypotheses. Extent-of-occurrence maps tend to be overly simple, omit many known and well-documented populations, and likely frequently include many areas not holding populations. Refinement steps involve typological assumptions about habitat preferences and elevational ranges of species, which can introduce substantial error in estimates of species' true areas of distribution. However, no model-evaluation steps are taken to assess the predictive ability of these models, so model inaccuracies are not noticed. Whereas range summaries derived by these methods may be useful in coarse-grained, global-extent studies, their continued use in on-the-ground conservation applications at fine spatial resolutions is not advisable in light of reliance on assumptions, lack of real spatial resolution, and lack of testing. In contrast, data-driven techniques that integrate primary data on biodiversity occurrence with remotely sensed data that summarize environmental dimensions (i.e., ecological niche modeling or species distribution modeling) offer data-driven solutions based on a minimum of assumptions that can be evaluated and validated quantitatively to offer a well-founded, widely accepted method for summarizing species' distributional patterns for conservation applications. © 2016 Society for Conservation Biology.

  9. Halo-Independent Direct Detection Analyses Without Mass Assumptions

    CERN Document Server

    Anderson, Adam J.; Kahn, Yonatan; McCullough, Matthew

    2015-10-06

    Results from direct detection experiments are typically interpreted by employing an assumption about the dark matter velocity distribution, with results presented in the $m_\\chi-\\sigma_n$ plane. Recently methods which are independent of the DM halo velocity distribution have been developed which present results in the $v_{min}-\\tilde{g}$ plane, but these in turn require an assumption on the dark matter mass. Here we present an extension of these halo-independent methods for dark matter direct detection which does not require a fiducial choice of the dark matter mass. With a change of variables from $v_{min}$ to nuclear recoil momentum ($p_R$), the full halo-independent content of an experimental result for any dark matter mass can be condensed into a single plot as a function of a new halo integral variable, which we call $\\tilde{h}(p_R)$. The entire family of conventional halo-independent $\\tilde{g}(v_{min})$ plots for all DM masses are directly found from the single $\\tilde{h}(p_R)$ plot through a simple re...

    2006-11-01

    This paper reports a study of what lesbian women and gay men had to say, as patients and as partners, about their experiences of nursing in hospital care, and what they regarded as important to communicate about homosexuality and nursing. The social life of heterosexual cultures is based on the assumption that all people are heterosexual, thereby making homosexuality socially invisible. Nurses may assume that all patients and significant others are heterosexual, and these heteronormative assumptions may lead to poor communication that affects nursing quality by leading nurses to ask the wrong questions and make incorrect judgements. A qualitative interview study was carried out in the spring of 2004. Seventeen women and 10 men ranging in age from 23 to 65 years from different parts of Sweden participated. They described 46 experiences as patients and 31 as partners. Heteronormativity was communicated in waiting rooms, in patient documents and when registering for admission, and nursing staff sometimes showed perplexity when an informant deviated from this heteronormative assumption. Informants had often met nursing staff who showed fear of behaving incorrectly, which could lead to a sense of insecurity, thereby impeding further communication. As partners of gay patients, informants felt that they had to deal with heterosexual assumptions more than they did when they were patients, and the consequences were feelings of not being accepted as a 'true' relative, of exclusion and neglect. Almost all participants offered recommendations about how nursing staff could facilitate communication. Heterosexual norms communicated unconsciously by nursing staff contribute to ambivalent attitudes and feelings of insecurity that prevent communication and easily lead to misconceptions. Educational and management interventions, as well as increased communication, could make gay people more visible and thereby encourage openness and awareness by hospital staff of the norms that they

    Policy-based management system provides the configuration capability for the system administrators to focus on the requirements of customers. The service level agreement performance monitoring mechanism helps system administrators to verify the correctness of policies. However, it is difficult for a device to process the policies directly because the policies are the management concept. This paper proposes a mechanism to decompose a policy into rules that can be efficiently processed by a device. Thus, the device may process the rule and collect the performance statistics information efficiently; and the policy-based management system may collect these performance statistics information and report the service-level agreement performance monitoring information to the system administrator. The proposed policy-based management system achieves both the policy configuration and service-level agreement performance monitoring requirements. A policy consists of a condition part and an action part. The condition part is a Boolean expression of a source host IP group, a destination host IP group, etc. The action part is the parameters of services. We say that an address group is compact if it only consists of a range of IP address that can be denoted by a pair of IP address and corresponding IP mask. If the condition part of a policy only consists of the compact address group, we say that the policy is a rule. Since a device can efficiently process a compact address and a system administrator prefers to define a range of IP address, the policy-based management system has to translate policy into rules and supplements the gaps between policy and rules. The proposed policy-based management system builds the relationships between VPN and policies, policy and rules. Since the system administrator wants to monitor the system performance information of VPNs and policies, the proposed policy-based management system downloads the relationships among VPNs, policies and rules to the

    This letter examines the effectiveness of various biofuel and climate policies in reducing future processing costs of cellulosic biofuels due to learning-by-doing. These policies include a biofuel production mandate alone and supplementing the biofuel mandate with other policies, namely a national low carbon fuel standard, a cellulosic biofuel production tax credit or a carbon price policy. We find that the binding biofuel targets considered here can reduce the unit processing cost of cellulosic ethanol by about 30% to 70% between 2015 and 2035 depending on the assumptions about learning rates and initial costs of biofuel production. The cost in 2035 is more sensitive to the speed with which learning occurs and less sensitive to uncertainty in the initial production cost. With learning rates of 5–10%, cellulosic biofuels will still be at least 40% more expensive than liquid fossil fuels in 2035. The addition of supplementary low carbon/tax credit policies to the mandate that enhance incentives for cellulosic biofuels can achieve similar reductions in these costs several years earlier than the mandate alone; the extent of these incentives differs across policies and different kinds of cellulosic biofuels.

    Data on individuals’ private shopping choices are often used to draw conclusions about their desires for food policies. The purpose of this paper is to test this often-implicit assumption using data from a nationwide survey about animal cloning. We find that although individuals’ private choices indicate a strong desire to avoid meat and milk from cloned cattle, public choices predict that only 40.29% have a positive WTP for such a ban. The results suggest caution is necessary when inferr...

  16. Oil price assumptions in macroeconomic forecasts: should we follow future market expectations?

    International Nuclear Information System (INIS)

    Coimbra, C.; Esteves, P.S.

    2004-01-01

    In macroeconomic forecasting, in spite of its important role in price and activity developments, oil prices are usually taken as an exogenous variable, for which assumptions have to be made. This paper evaluates the forecasting performance of futures market prices against the other popular technical procedure, the carry-over assumption. The results suggest that there is almost no difference between opting for futures market prices or using the carry-over assumption for short-term forecasting horizons (up to 12 months), while, for longer-term horizons, they favour the use of futures market prices. However, as futures market prices reflect market expectations for world economic activity, futures oil prices should be adjusted whenever market expectations for world economic growth are different to the values underlying the macroeconomic scenarios, in order to fully ensure the internal consistency of those scenarios.

    Being kind of intuitive psychology the 'Revealed-Preferences'- theory based approaches towards determining the acceptable risks are a useful method for the generation of hypotheses. In view of the fact that reliability engineering develops faster than methods for the determination of reliability aims the Revealed-Preferences approach is a necessary preliminary help. Some of the assumptions on which the 'Revealed-Preferences' theory is based will be identified and analysed and afterwards compared with experimentally obtained results. (orig./DG) [de

  19. Travel demand policies for saving oil during a supply emergency

    2006-01-01

    An area of growing concern is the future stability of oil producing regions and the ability to maintain stability in international petroleum markets. The transport sector, in particular, is extremely vulnerable to short-term supply disruptions with consequent implications on economic activities in most countries. This paper analyses potential transport demand restraint strategies that could potentially mitigate the impact of short-term supply disruptions. Our analysis includes estimates of the potential fuel savings from several policies. Specifically, we examine various work-based policies (telecommuting, flexible work schedules), the potential of carpooling, speed limit reductions, driving bans and restrictions, increased public transport usage, and providing information on the effect of maintaining optimal tire pressures. The analysis uses various assumptions based on existing knowledge about how travelers may respond under emergency conditions to develop estimates of potential fuel savings. Results suggest that the most restrictive policies, such as driving bans and mandatory carpooling are the most effective. Other policies provide small reductions with some, such as telecommuting and flexible work schedules, having the potential to be easily implemented. Those policies, focussed on encouraging public transport use, are less effective and potentially more costly to implement

  1. Integrated Management of Migration, Employment, Fiscal Policy and Public Debt

    Directory of Open Access Journals (Sweden)

    Aleksandras Vytautas Rutkauskas

    2013-09-01

    Full Text Available The main idea of the paper states that national migration indicators are closely related with employment opportunities in that country. In addition, the management quality of migration and employment processes is an indicator of the national socio-economic policy competency, while management of these processes is the main purpose of intelligent adjustment of the national fiscal policy and government debt management. The author of the paper selected the formation of the system of quantitative indicators as the main objective of the paper. The system should allow employing government debt possibilities for the selection of proper fiscal policy in order to prevent the transformation of unemployment into the key reason of uncontrolled national inflation. This would be done by revealing the possibilities of fiscal policy to impact on the level and structure of unemployment. Recent globalisation processes and integration possibilities bring a lot of uncertainty to predetermined viability of theoretical assumptions as well as the adequacy of the applied quantitative methods. The paper uses the possibilities of stochastic optimisation and stochastically informed expertise pursuing the possibilities of integrated management of employment, migration processes, fiscal policy and government debt provisions.

Ideologies are closely linked to power and language because using language is the commonest form of social behavior, and the form of social behavior where we rely most on ‘common-sense’ assumptions. The objectives of this study are to discuss the common sense assumption and ideology by means of language use in SBY’s political speech which is mainly grounded in Norman Fairclough’s theory of language and power in critical discourse analysis. There are two main problems of analysis, namely; first, what are the common sense assumption and ideology in Susilo Bambang Yudhoyono’s political speech; and second, how do they relate to each other in the political discourse? The data used in this study was in the form of written text on “moving towards sustainability: together we must create the future we want”. A qualitative descriptive analysis was employed to analyze the common sense assumption and ideology in the written text of Susilo Bambang Yudhoyono’s political speech which was delivered at Riocto entro Convention Center, Rio de Janeiro on June 20, 2012. One dimension of ‘common sense’ is the meaning of words. The results showed that the common sense assumption and ideology conveyed through SBY’s specific words or expressions can significantly explain how political discourse is constructed and affected by the SBY’s rule and position, life experience, and power relations. He used language as a powerful social tool to present his common sense assumption and ideology to convince his audiences and fellow citizens that the future of sustainability has been an important agenda for all people.

  3. Fiscal ethics, policies, and theories

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available The connections between ethics, policies and economic theories regarding fiscal matters need a more thorough analysis than the one carried out so far. On one hand, even though there are some ethical proposals on taxation, in general such proposals have not been grounded on explanatory theories of the economy. On the other hand, schools of thought about economy usually fail to ethically justify their political proposals. However, such distinctions cannot be sustained rationally: any ethical proposal concerning fiscal matters involves an explanation of economy, and conversely any proposal related to fiscal policies does not only involve a theory but also an ethical understanding. This article will review such connections, and general conclusions will be applied to two specific cases: first, Rawls’s proposal concerning taxation will be reviewed, having previously studied its descriptive assumptions, and then the lack of an ethical connection between the post Keynesian theory on the monetary circuit and its fiscal proposal will be examined. Finally, a possible “taxation compliance ethic” of tax-payers will be likewise analysed.

  12. Commentary: Considering Assumptions in Associations Between Music Preferences and Empathy-Related Responding

    Directory of Open Access Journals (Sweden)

    Susan A O'Neill

    2015-09-01

    Full Text Available This commentary considers some of the assumptions underpinning the study by Clark and Giacomantonio (2015. Their exploratory study examined relationships between young people's music preferences and their cognitive and affective empathy-related responses. First, the prescriptive assumption that music preferences can be measured according to how often an individual listens to a particular music genre is considered within axiology or value theory as a multidimensional construct (general, specific, and functional values. This is followed by a consideration of the causal assumption that if we increase young people's empathy through exposure to prosocial song lyrics this will increase their prosocial behavior. It is suggested that the predictive power of musical preferences on empathy-related responding might benefit from a consideration of the larger pattern of psychological and subjective wellbeing within the context of developmental regulation across ontogeny that involves mutually influential individual—context relations.

  13. Big Data for Public Health Policy-Making: Policy Empowerment.

    2018-04-04

    Digitization is considered to radically transform healthcare. As such, with seemingly unlimited opportunities to collect data, it will play an important role in the public health policy-making process. In this context, health data cooperatives (HDC) are a key component and core element for public health policy-making and for exploiting the potential of all the existing and rapidly emerging data sources. Being able to leverage all the data requires overcoming the computational, algorithmic, and technological challenges that characterize today's highly heterogeneous data landscape, as well as a host of diverse regulatory, normative, governance, and policy constraints. The full potential of big data can only be realized if data are being made accessible and shared. Treating research data as a public good, creating HDC to empower citizens through citizen-owned health data, and allowing data access for research and the development of new diagnostics, therapies, and public health policies will yield the transformative impact of digital health. The HDC model for data governance is an arrangement, based on moral codes, that encourages citizens to participate in the improvement of their own health. This then enables public health institutions and policymakers to monitor policy changes and evaluate their impact and risk on a population level. © 2018 S. Karger AG, Basel.

  14. New Assumptions to Guide SETI Research

    2018-01-01

    The recent Kepler discoveries of Earth-like planets offer the opportunity to focus our attention on detecting signs of life and technology in specific planetary systems, but I feel we need to become more flexible in our assumptions. The reason is that, while it is still reasonable and conservative to assume that life is most likely to have originated in conditions similar to ours, the vast time differences in potential evolutions render the likelihood of "matching" technologies very slim. In light of these challenges I propose a more "aggressive"� approach to future SETI exploration in directions that until now have received little consideration.

    Cisneros-Montemayor, Andrés M; Singh, Gerald G; Cheung, William W L

    2017-12-16

    Evaluating progress towards environmental sustainability goals can be difficult due to a lack of measurable benchmarks and insufficient or uncertain data. Marine settings are particularly challenging, as stakeholders and objectives tend to be less well defined and ecosystem components have high natural variability and are difficult to observe directly. Fuzzy logic expert systems are useful analytical frameworks to evaluate such systems, and we develop such a model here to formally evaluate progress towards sustainability targets based on diverse sets of indicators. Evaluation criteria include recent (since policy enactment) and historical (from earliest known state) change, type of indicators (state, benefit, pressure, response), time span and spatial scope, and the suitability of an indicator in reflecting progress toward a specific objective. A key aspect of the framework is that all assumptions are transparent and modifiable to fit different social and ecological contexts. We test the method by evaluating progress towards four Aichi Biodiversity Targets in Canadian oceans, including quantitative progress scores, information gaps, and the sensitivity of results to model and data assumptions. For Canadian marine systems, national protection plans and biodiversity awareness show good progress, but species and ecosystem states overall do not show strong improvement. Well-defined goals are vital for successful policy implementation, as ambiguity allows for conflicting potential indicators, which in natural systems increases uncertainty in progress evaluations. Importantly, our framework can be easily adapted to assess progress towards policy goals with different themes, globally or in specific regions.

  1. Questionable assumptions hampered interpretation of a network meta-analysis of primary care depression treatments.

    Science.gov (United States)

    Linde, Klaus; Rücker, Gerta; Schneider, Antonius; Kriston, Levente

    2016-03-01

    We aimed to evaluate the underlying assumptions of a network meta-analysis investigating which depression treatment works best in primary care and to highlight challenges and pitfalls of interpretation under consideration of these assumptions. We reviewed 100 randomized trials investigating pharmacologic and psychological treatments for primary care patients with depression. Network meta-analysis was carried out within a frequentist framework using response to treatment as outcome measure. Transitivity was assessed by epidemiologic judgment based on theoretical and empirical investigation of the distribution of trial characteristics across comparisons. Homogeneity and consistency were investigated by decomposing the Q statistic. There were important clinical and statistically significant differences between "pure" drug trials comparing pharmacologic substances with each other or placebo (63 trials) and trials including a psychological treatment arm (37 trials). Overall network meta-analysis produced results well comparable with separate meta-analyses of drug trials and psychological trials. Although the homogeneity and consistency assumptions were mostly met, we considered the transitivity assumption unjustifiable. An exchange of experience between reviewers and, if possible, some guidance on how reviewers addressing important clinical questions can proceed in situations where important assumptions for valid network meta-analysis are not met would be desirable.

    In order to shed light on understanding the subgrid-scale (SGS) modelling methodology, we analyze and define the concepts of assumption and restriction in the modelling procedure, then show by a generalized derivation that if there are multiple stationary restrictions in a modelling, the corresponding assumption function must satisfy a criterion of orthogonality. Numerical tests using one-dimensional nonlinear advection equation are performed to validate this criterion. This study is expected to inspire future research on generally guiding the SGS modelling methodology. - Highlights: • The concepts of assumption and restriction in the SGS modelling procedure are defined. • A criterion of orthogonality on the assumption and restrictions is derived. • Numerical tests using one-dimensional nonlinear advection equation are performed to validate this criterion.

  9. Collective health and family medicine

    Directory of Open Access Journals (Sweden)

    Donovan Casas Patiño

    2013-05-01

    Full Text Available In Mexico, the arrangement of clinical practice has been influenced by a decision-making process that seeks to improve health indicators, thus transforming the patient into a number. Family medicine has been practiced within the limits of an institutional biomedical model where the health-disease process is approached from a biologist perspective. On the other hand, collective health understands this process as stemming from the collective sphere and includes social and biological perspectives, giving an important standing to society. Likewise, it puts policy as a determinant in bettering social health bringing together public policy with health matters. Family medicine must become the axis around which health needs are catered to, together with social conditioning factors that affect families and individuals. This leads to a trans-disciplinary approach to communities set free from a mere biomedical profile. In this context, collective health provides theoretical support to the upcoming debate on family medicine.

  11. Semi-supervised learning via regularized boosting working on multiple semi-supervised assumptions.

    Science.gov (United States)

    Chen, Ke; Wang, Shihai

    2011-01-01

    Semi-supervised learning concerns the problem of learning in the presence of labeled and unlabeled data. Several boosting algorithms have been extended to semi-supervised learning with various strategies. To our knowledge, however, none of them takes all three semi-supervised assumptions, i.e., smoothness, cluster, and manifold assumptions, together into account during boosting learning. In this paper, we propose a novel cost functional consisting of the margin cost on labeled data and the regularization penalty on unlabeled data based on three fundamental semi-supervised assumptions. Thus, minimizing our proposed cost functional with a greedy yet stagewise functional optimization procedure leads to a generic boosting framework for semi-supervised learning. Extensive experiments demonstrate that our algorithm yields favorite results for benchmark and real-world classification tasks in comparison to state-of-the-art semi-supervised learning algorithms, including newly developed boosting algorithms. Finally, we discuss relevant issues and relate our algorithm to the previous work.

  12. Financing and funding health care: Optimal policy and political implementability.

    Science.gov (United States)

    Nuscheler, Robert; Roeder, Kerstin

    2015-07-01

    Health care financing and funding are usually analyzed in isolation. This paper combines the corresponding strands of the literature and thereby advances our understanding of the important interaction between them. We investigate the impact of three modes of health care financing, namely, optimal income taxation, proportional income taxation, and insurance premiums, on optimal provider payment and on the political implementability of optimal policies under majority voting. Considering a standard multi-task agency framework we show that optimal health care policies will generally differ across financing regimes when the health authority has redistributive concerns. We show that health care financing also has a bearing on the political implementability of optimal health care policies. Our results demonstrate that an isolated analysis of (optimal) provider payment rests on very strong assumptions regarding both the financing of health care and the redistributive preferences of the health authority.

  14. Anti-Atheist Bias in the United States: Testing Two Critical Assumptions

    Directory of Open Access Journals (Sweden)

    Lawton K Swan

    2012-02-01

    Full Text Available Decades of opinion polling and empirical investigations have clearly demonstrated a pervasive anti-atheist prejudice in the United States. However, much of this scholarship relies on two critical and largely unaddressed assumptions: (a that when people report negative attitudes toward atheists, they do so because they are reacting specifically to their lack of belief in God; and (b that survey questions asking about attitudes toward atheists as a group yield reliable information about biases against individual atheist targets. To test these assumptions, an online survey asked a probability-based random sample of American adults (N = 618 to evaluate a fellow research participant (“Jordan”. Jordan garnered significantly more negative evaluations when identified as an atheist than when described as religious or when religiosity was not mentioned. This effect did not differ as a function of labeling (“atheist” versus “no belief in God”, or the amount of individuating information provided about Jordan. These data suggest that both assumptions are tenable: nonbelief—rather than extraneous connotations of the word “atheist”—seems to underlie the effect, and participants exhibited a marked bias even when confronted with an otherwise attractive individual.

    Directory of Open Access Journals (Sweden)

    Gajewski Marek

    2017-06-01

    Full Text Available In the context of increasing globalization, global competition and rapid change the EU sees innovation and its commercialization as an effective way to build long-term global competitive advantage. Innovation policy is a link between research and technological development policy and industrial policy and makes it possible to create conditions conducive to bringing ideas to the market. It is also closely linked to other EU policies regarding e.g. employment, competitiveness, environment, industry and energy. This paper presents the evolution, conditions and objectives of the innovation policy of the European, and describes the main assumptions of the Lisbon and Europe 2020 strategies. Additionally it indicates possible ways of assessing the measures undertaken within the above-mentioned policies and of determining the tools necessary to implement the strategies.

    Directory of Open Access Journals (Sweden)

    Savenkova Aleksandra Igorevna

    2016-08-01

    Full Text Available This article is devoted to an architectural and historical analysis of the constructions forming a complex of Assumption Cathedral of the Astrakhan Kremlin, which earlier hasn’t been considered as a subject of special research. Basing on the archival sources, photographic materials, publications and on-site investigations of monuments, the creation history of the complete architectural complex sustained in one style of the Muscovite baroque, unique in its composite construction, is considered. Its interpretation in the all-Russian architectural context is offered. Typological features of single constructions come to light. The typology of the Prechistinsky bell tower has an untypical architectural solution - “hexagonal structure on octagonal and quadrangular structures”. The way of connecting the building of the Cathedral and the chambers by the passage was characteristic of monastic constructions and was exclusively seldom in kremlins, farmsteads and ensembles of city cathedrals. The composite scheme of the Assumption Cathedral includes the Lobnoye Mesto (“the Place of Execution” located on an axis from the West, it is connected with the main building by a quarter-turn with landing. The only prototype of the structure is a Lobnoye Mesto on the Red Square in Moscow. In the article the version about the emergence of the Place of Execution on the basis of earlier existing construction - a tower “the Peal” which is repeatedly mentioned in written sources in connection with S. Razin’s revolt is considered. The metropolitan Sampson, trying to keep the value of the Astrakhan metropolitanate, builds the Assumption Cathedral and the Place of Execution directly appealing to a capital prototype to emphasize the continuity and close connection with Moscow.

  4. Policy Design for Competitive Retail Electric Institutions: Artificial Intelligence Representations for a Common Property Resource Approach

    Science.gov (United States)

    Pandit, Nitin S.

    The U.S. electricity industry is being restructured to increase competition. Although existing policies may lead to efficient wholesale institutions, designing policies for the retail level is more complex because of intricate interactions between individuals and quasi-monopolistic institutions. It is argued that Hirshman's ideas of "exit" and "voice" (Hirshman, 1970) provide powerful abstractions for design of retail institutions. While competition is a known mechanism of "exit," a novel design of the "voice" mechanism is demonstrated through an artificial intelligence (AI) based software process model. The process model of "voice" in retail institutions is designed within the economic context of electricity distribution -- a common property resource (CPR), characterized by technological uncertainty and path-dependency. First, it is argued that participant feedback (voice) has to be used effectively to manage the CPR. Further, it is noted that the decision process, of using participant feedback (voice) to incrementally manage uncertainty and path-dependencies, is non-monotonic because it requires the decision makers to often retract previously made assumptions and decisions. An AI based process model of "voice" is developed using an assumption-based truth maintenance system. The model can emulate the non-monotonic decision making process and therefore assist in decision support. Such a systematic framework is flexible, consistent, and easily reorganized as assumptions change. It can provide an effective, formal "voice" mechanism to the retail customers and improve institutional performance.

    A feasible experiment is discussed which allows us to prove a Bell's theorem for two particles without using an inequality. The experiment could be used to test local realism against quantum mechanics without the introduction of additional assumptions related to hidden variables states. Only assumptions based on direct experimental observation are needed.

  7. Statistical power to detect violation of the proportional hazards assumption when using the Cox regression model.

    Science.gov (United States)

    Austin, Peter C

    2018-01-01

    The use of the Cox proportional hazards regression model is widespread. A key assumption of the model is that of proportional hazards. Analysts frequently test the validity of this assumption using statistical significance testing. However, the statistical power of such assessments is frequently unknown. We used Monte Carlo simulations to estimate the statistical power of two different methods for detecting violations of this assumption. When the covariate was binary, we found that a model-based method had greater power than a method based on cumulative sums of martingale residuals. Furthermore, the parametric nature of the distribution of event times had an impact on power when the covariate was binary. Statistical power to detect a strong violation of the proportional hazards assumption was low to moderate even when the number of observed events was high. In many data sets, power to detect a violation of this assumption is likely to be low to modest.

  12. Policy framework for utilisation. A pillar of better accessibility

    International Nuclear Information System (INIS)

    2008-01-01

    The goals and frameworks for traffic and transport policy for the Netherlands to 2020 are described in the Mobility Document. Whereas government policy previously viewed mobility as a problem or as something permissible, the assumption is now that mobility is a must. Mobility, for people as well as goods, is a prerequisite for society and the economy to function well. The Mobility Document contains ambitious goals to deal with current and anticipated traffic and transport problems: door to door, faster, cleaner and safer. Three interrelated pillars are to help achieve these goals: Building, Pricing and Utilisation. Work is being done on the Building and Pricing pillars; Utilisation is elaborated further in this policy framework. The Policy Framework for Utilisation is an elaboration of the Mobility Document for the 2008-2020 period and aims for faster, cleaner, safer travel from door to door. The purpose of this policy framework is to describe the direction of development of utilisation, in terms of content as well as process, to indicate actions that are required and to provide perspective on the expected effects. The policy framework is in line with current developments or plans, caters to new opportunities (technological and otherwise), encourages the innovative potential of the market and provides room for joint ventures between the government and the market. It will result in actions for the short term and provide direction for activities and developments for the longer term

  13. Residential applliance data, assumptions and methodology for end-use forecasting with EPRI-REEPS 2.1

    Hwang, R.J,; Johnson, F.X.; Brown, R.E.; Hanford, J.W.; Kommey, J.G.

    1994-05-01

    This report details the data, assumptions and methodology for end-use forecasting of appliance energy use in the US residential sector. Our analysis uses the modeling framework provided by the Appliance Model in the Residential End-Use Energy Planning System (REEPS), which was developed by the Electric Power Research Institute. In this modeling framework, appliances include essentially all residential end-uses other than space conditioning end-uses. We have defined a distinct appliance model for each end-use based on a common modeling framework provided in the REEPS software. This report details our development of the following appliance models: refrigerator, freezer, dryer, water heater, clothes washer, dishwasher, lighting, cooking and miscellaneous. Taken together, appliances account for approximately 70% of electricity consumption and 30% of natural gas consumption in the US residential sector. Appliances are thus important to those residential sector policies or programs aimed at improving the efficiency of electricity and natural gas consumption. This report is primarily methodological in nature, taking the reader through the entire process of developing the baseline for residential appliance end-uses. Analysis steps documented in this report include: gathering technology and market data for each appliance end-use and specific technologies within those end-uses, developing cost data for the various technologies, and specifying decision models to forecast future purchase decisions by households. Our implementation of the REEPS 2.1 modeling framework draws on the extensive technology, cost and market data assembled by LBL for the purpose of analyzing federal energy conservation standards. The resulting residential appliance forecasting model offers a flexible and accurate tool for analyzing the effect of policies at the national level.

  15. Application of random survival forests in understanding the determinants of under-five child mortality in Uganda in the presence of covariates that satisfy the proportional and non-proportional hazards assumption.

    2017-09-07

    Uganda just like any other Sub-Saharan African country, has a high under-five child mortality rate. To inform policy on intervention strategies, sound statistical methods are required to critically identify factors strongly associated with under-five child mortality rates. The Cox proportional hazards model has been a common choice in analysing data to understand factors strongly associated with high child mortality rates taking age as the time-to-event variable. However, due to its restrictive proportional hazards (PH) assumption, some covariates of interest which do not satisfy the assumption are often excluded in the analysis to avoid mis-specifying the model. Otherwise using covariates that clearly violate the assumption would mean invalid results. Survival trees and random survival forests are increasingly becoming popular in analysing survival data particularly in the case of large survey data and could be attractive alternatives to models with the restrictive PH assumption. In this article, we adopt random survival forests which have never been used in understanding factors affecting under-five child mortality rates in Uganda using Demographic and Health Survey data. Thus the first part of the analysis is based on the use of the classical Cox PH model and the second part of the analysis is based on the use of random survival forests in the presence of covariates that do not necessarily satisfy the PH assumption. Random survival forests and the Cox proportional hazards model agree that the sex of the household head, sex of the child, number of births in the past 1 year are strongly associated to under-five child mortality in Uganda given all the three covariates satisfy the PH assumption. Random survival forests further demonstrated that covariates that were originally excluded from the earlier analysis due to violation of the PH assumption were important in explaining under-five child mortality rates. These covariates include the number of children under the

  19. Validity of the isotropic thermal conductivity assumption in supercell lattice dynamics

    Science.gov (United States)

    Ma, Ruiyuan; Lukes, Jennifer R.

    2018-02-01

    Superlattices and nano phononic crystals have attracted significant attention due to their low thermal conductivities and their potential application as thermoelectric materials. A widely used expression to calculate thermal conductivity, presented by Klemens and expressed in terms of the relaxation time by Callaway and Holland, originates from the Boltzmann transport equation. In its most general form, this expression involves a direct summation of the heat current contributions from individual phonons of all wavevectors and polarizations in the first Brillouin zone. In common practice, the expression is simplified by making an isotropic assumption that converts the summation over wavevector to an integral over wavevector magnitude. The isotropic expression has been applied to superlattices and phononic crystals, but its validity for different supercell sizes has not been studied. In this work, the isotropic and direct summation methods are used to calculate the thermal conductivities of bulk Si, and Si/Ge quantum dot superlattices. The results show that the differences between the two methods increase substantially with the supercell size. These differences arise because the vibrational modes neglected in the isotropic assumption provide an increasingly important contribution to the thermal conductivity for larger supercells. To avoid the significant errors that can result from the isotropic assumption, direct summation is recommended for thermal conductivity calculations in superstructures.

  20. Irrigation water policy analysis using a business simulation game

    Buchholz, M.; Holst, G.; Musshoff, O.

    2016-10-01

    Despite numerous studies on farmers' responses to changing irrigation water policies, uncertainties remain about the potential of water pricing schemes and water quotas to reduce irrigation. Thus far, policy impact analysis is predominantly based upon rational choice models that assume behavioral assumptions, such as a perfectly rational profit-maximizing decision maker. Also, econometric techniques are applied which could lack internal validity due to uncontrolled field data. Furthermore, such techniques are not capable of identifying ill-designed policies prior to their implementation. With this in mind, we apply a business simulation game for ex ante policy impact analysis of irrigation water policies at the farm level. Our approach has the potential to reveal the policy-induced behavioral change of the participants in a controlled environment. To do so, we investigate how real farmers from Germany, in an economic experiment, respond to a water pricing scheme and a water quota intending to reduce irrigation. In the business simulation game, the participants manage a "virtual" cash-crop farm for which they make crop allocation and irrigation decisions during several production periods, while facing uncertain product prices and weather conditions. The results reveal that a water quota is able to reduce mean irrigation applications, while a water pricing scheme does not have an impact, even though both policies exhibit equal income effects for the farmers. However, both policies appear to increase the variation of irrigation applications. Compared to a perfectly rational profit-maximizing decision maker, the participants apply less irrigation on average, both when irrigation is not restricted and when a water pricing scheme applies. Moreover, the participants' risk attitude affects the irrigation decisions.

  1. The impact of luxury brand identity on product pricing policy

    Wioleta Dryl

    2013-12-01

    Full Text Available Basing the luxury product pricing policy, only on the assumption that the price has to be the highest amount a client is willing to pay, poses a number of challenges in front of enterprise. The consumer of the luxury product is very aware of his needs and expectations. He is ready to pay a higher price for the product, but is expecting to return, very specific values. Relying luxury brand strategy, only on high-priced, without enrichment offer to a sufficiently high level leads to market failure. The justification for the high price of the product may, however, be defined brand image, which is a consequence of appropriate policies shaping its identity. In the case of luxury goods, especially essential tool proves to be the emotional component of the brand identity.

    2017-04-01

    Cigarette consumption has become global threat to both smokers and organizations. However, little is known about organizational smoking and vaping policies, and their influence to employees' smoking and vaping behavior. We collected data from 456 employed smokers, vapers, and/or dual users. Smoking and/or vaping behavior, along with perceived organizational smoking/vaping policies were examined. Vapers reported perceiving more stringent smoking policy, while vapers who reported having workplace vaping policies perceived having generally more stringent vaping policy. Most smokers and vapers are well informed about smoking policy; however, a considerable portion of them do not have a good understanding about organizational vaping policy. Organizations should not consider smoking and vaping to be the same when setting policy. Employers should ensure that organizational vaping policies are present and clear to all employees.

  5. Visions of Alternative (Unpredictable Futures and Their Use in Policy Analysis

    Directory of Open Access Journals (Sweden)

    Robert Costanza

    2000-07-01

    Full Text Available The most critical task facing humanity today is the creation of a shared vision of a sustainable and desirable society, one that can provide permanent prosperity within the biophysical constraints of the real world in a way that is fair and equitable to all of humanity, to other species, and to future generations. Recent work with businesses and communities indicates that creating a shared vision is the most effective engine for change in the desired direction, yet most effort in "futures modeling" has focused on extrapolating past trends rather than envisioning alternative futures. Science and economics as applied to policy are in conflict more often over alternative visions of the world than purely "scientific" disagreements. Likewise, governance has gotten bogged down in mediating short term conflicts between special interests rather than its more basic role of creating broadly shared visions that can guide dispute resolution. This paper addresses the question of what policies are most appropriate for society now, given alternative visions of the future and the enormous uncertainty about the reality of the assumptions underlying these visions. Four specific visions are laid out as being representative of the major alternatives. For each vision the benefits of achieving the vision, the assumptions that would have to be true in order for it to be achieved, and the implications of it being attempted but not achieved are explored. It is argued that dealing with uncertainty about the nature of the world, its carrying capacity for humans, the impacts of climate change, and other aspects of its future can best be done at this level of future visions and assumptions, not at more detailed levels (like the parameter uncertainty in models. Application of this vision/uncertainty analysis can help us both to design the future society we want and to maximize the chances of our getting there safely.

    International Nuclear Information System (INIS)

    Hoff, T.; Wenger, H.J.; Keane, D.M.

    1993-01-01

    Pacific Gas and Electric Company (PG ampersand E) recently applied Demand-Side Management (DSM) evaluation techniques to photovoltaic (PV) technology to develop the concept of photovoltaics as a Demand-Side Management option (PV-DSM). The analysis demonstrated that PV-DSM has the potential to be economically attractive. Two criticisms in response to that analysis are that the assumptions of 25 year financing and a 25 year evaluation period are unrealistic. This paper responds to those criticisms and documents the mathematical relationships to calculate the value of PV-DSM from a customer's perspective. It demonstrates how regulatory and government agencies could implement policies to resolve both issues and speed PV commercialization

  12. Modeling investment uncertainty in the costs of global CO2 emission policy

    International Nuclear Information System (INIS)

    Birge, J.R.; Rosa, C.H.

    1995-01-01

    This paper investigates the effect that explicit modeling of stochastic returns to investment has on the CO 2 abatement policy returned by a large scale macroeconomic model of the United States economy. It was found that a policy derived from the mean value deterministic model in which the random variables of the stochastic model have been replaced by their expected value poorly approximates the optimal policy returned by solving the stochastic programming model. This nonoptimality is measured by determining the value of the stochastic solution and investigating the different evolutionary paths that various macroeconomic variables follow. Macroeconomic variables which stray far from their optimal paths when derived under the assumption of a certain mean valued future are as follows: the level of carbon taxation, investment in new energy production technologies, exploration for nonrenewable resources and investment in improved macroeconomic efficiency. 18 refs., 17 figs., 6 tabs

  13. Fair-sampling assumption is not necessary for testing local realism

    Berry, Dominic W.; Jeong, Hyunseok; Stobinska, Magdalena; Ralph, Timothy C.

    2010-01-01

    Almost all Bell inequality experiments to date have used postselection and therefore relied on the fair sampling assumption for their interpretation. The standard form of the fair sampling assumption is that the loss is independent of the measurement settings, so the ensemble of detected systems provides a fair statistical sample of the total ensemble. This is often assumed to be needed to interpret Bell inequality experiments as ruling out hidden-variable theories. Here we show that it is not necessary; the loss can depend on measurement settings, provided the detection efficiency factorizes as a function of the measurement settings and any hidden variable. This condition implies that Tsirelson's bound must be satisfied for entangled states. On the other hand, we show that it is possible for Tsirelson's bound to be violated while the Clauser-Horne-Shimony-Holt (CHSH)-Bell inequality still holds for unentangled states, and present an experimentally feasible example.

    To compare public and policy maker support for three point-of-sale tobacco policies. Two cross-sectional surveys--one of the public from the New York Adult Tobacco Survey and one of policy makers from the Local Opinion Leader Survey; both collected and analyzed in 2011. Tobacco control programs focus on educating the public and policy makers about tobacco control policy solutions. Six hundred seventy-six county-level legislators in New York's 62 counties and New York City's five boroughs (response rate: 59%); 7439 New York residents aged 18 or older. Landline response rates: 20.2% to 22%. Cell phone response rates: 9.2% to 11.1%. Gender, age, smoking status, presence of a child aged 18 years or younger in the household, county of residence, and policy maker and public support for three potential policy solutions to point-of-sale tobacco marketing. t-tests to compare the demographic makeup for the two samples. Adjusted Wald tests to test for differences in policy support between samples. The public was significantly more supportive of point-of-sale policy solutions than were policy makers: cap on retailers (48.0% vs. 19.2%, respectively); ban on sales at pharmacies (49.1% vs. 38.8%); and ban on retailers near schools (53.3% vs. 42.5%). cross-sectional data, sociodemographic differences, and variations in item wording. Tobacco control programs need to include information about implementation, enforcement, and potential effects on multiple constituencies (including businesses) in their efforts to educate policy makers about point-of-sale policy solutions.

  18. Are Prescription Opioids Driving the Opioid Crisis? Assumptions vs Facts.

    Science.gov (United States)

    Rose, Mark Edmund

    2018-04-01

    Sharp increases in opioid prescriptions, and associated increases in overdose deaths in the 2000s, evoked widespread calls to change perceptions of opioid analgesics. Medical literature discussions of opioid analgesics began emphasizing patient and public health hazards. Repetitive exposure to this information may influence physician assumptions. While highly consequential to patients with pain whose function and quality of life may benefit from opioid analgesics, current assumptions about prescription opioid analgesics, including their role in the ongoing opioid overdose epidemic, have not been scrutinized. Information was obtained by searching PubMed, governmental agency websites, and conference proceedings. Opioid analgesic prescribing and associated overdose deaths both peaked around 2011 and are in long-term decline; the sharp overdose increase recorded in 2014 was driven by illicit fentanyl and heroin. Nonmethadone prescription opioid analgesic deaths, in the absence of co-ingested benzodiazepines, alcohol, or other central nervous system/respiratory depressants, are infrequent. Within five years of initial prescription opioid misuse, 3.6% initiate heroin use. The United States consumes 80% of the world opioid supply, but opioid access is nonexistent for 80% and severely restricted for 4.1% of the global population. Many current assumptions about opioid analgesics are ill-founded. Illicit fentanyl and heroin, not opioid prescribing, now fuel the current opioid overdose epidemic. National discussion has often neglected the potentially devastating effects of uncontrolled chronic pain. Opioid analgesic prescribing and related overdoses are in decline, at great cost to patients with pain who have benefited or may benefit from, but cannot access, opioid analgesic therapy.

  19. Policy, sport and integration

    DEFF Research Database (Denmark)

    Agergaard, Sine; Sørensen, Jan Kahr

    2010-01-01

    Increased public funding, more governmental involvement and an emphasis on the instrumental values of physical activities have in general become characteristic of Western nations’ policies towards sport. Denmark is, however, a little different in that there is still little political intervention...... in sport, although sports clubs do get economic support and are seen as having the potential to solve crucial social issues. The purpose of this article is to analyse and discuss the ways in which the political assumption that sport can enhance social integration is reflected in the practical governance...... of integration issues in particular in sports clubs. The article is based on a local field study in which we interviewed 10 talented football players with ethnic minority backgrounds and eight coaches and club leaders from six different football clubs. Distinguishing between integration and assimilation...

  1. [Marxism as a theoretical and methodological framework in collective health: implications for systematic review and synthesis of evidence].

    Science.gov (United States)

    Soares, Cassia Baldini; Campos, Celia Maria Sivalli; Yonekura, Tatiana

    2013-12-01

    In this study, we discuss the integration in systematic reviews of research developed from a Marxist perspective of knowledge production and their results as evidence in healthcare. The study objectives are to review the assumptions of dialectical and historical materialism (DHM) and discuss the implications of dialectics for a literature review and the synthesis of evidence. DHM is a powerful framework for knowledge generation and transformation of policies and practices in healthcare. It assumes that social contradictions underlie the health-disease process, the fundamental theoretical construction in the field of collective health. Currently, we observe a considerable influence of the critical paradigm, of Marxist origin, in the construction of knowledge in health. Studies based on this critical paradigm incorporate complex methods, which are inherent to the guidelines of dialect, to identify the object and arrive at results that constitute evidence in healthcare. Systematic reviews should address the methodological difficulties associated with entirely integrating these results to healthcare.

  2. Making sense of the global health crisis: policy narratives, conflict, and global health governance.

    Science.gov (United States)

    Ney, Steven

    2012-04-01

    Health has become a policy issue of global concern. Worried that the unstructured, polycentric, and pluralist nature of global health governance is undermining the ability to serve emergent global public health interests, some commentators are calling for a more systematic institutional response to the "global health crisis." Yet global health is a complex and uncertain policy issue. This article uses narrative analysis to explore how actors deal with these complexities and how uncertainties affect global health governance. By comparing three narratives in terms of their basic assumptions, the way they define problems as well as the solutions they propose, the analysis shows how the unstructured pluralism of global health policy making creates a wide scope of policy conflict over the global health crisis. This wide scope of conflict enables effective policy-oriented learning about global health issues. The article also shows how exclusionary patterns of cooperation and competition are emerging in health policy making at the global level. These patterns threaten effective learning by risking both polarization of the policy debate and unanticipated consequences of health policy. Avoiding these pitfalls, the analysis suggests, means creating global health governance regimes that promote openness and responsiveness in deliberation about the global health crisis.

  3. Social Welfare Policy in an Information Age: New Vision or More of the Same?

    Directory of Open Access Journals (Sweden)

    John G. McNutt

    2005-05-01

    Full Text Available As we move into the 21st Century, the social policy enterprise stands as the nexus between technological, political and social forces that will undermine the base that contemporary programs and policies depend upon. Assumptions about work and the workforce, the nature of governance and the role of technology will radically change. If our social welfare system is to remain relevant, changes will be needed. This paper explores these changing systems and examines how they will influence the current system. It will also speculate on the types of changes that will be necessary if social welfare is to remain relevant to the society of the future.

  7. MOTIVES FOR ASSET REVALUATION POLICY CHOICE IN CROATIA

    Directory of Open Access Journals (Sweden)

    Željana Aljinović Barać

    2011-02-01

    Full Text Available The aim of this paper is to research managers’ motives of accounting policy choice for long-term nonfinancial assets. International Financial Reporting Standards (IFRS allow managers to choose between cost and revaluation model for measurement after recognition. The assumption is that manager’s decision is opportunistic so they use the revaluation model as a device to improve perceptive borrowing capacity of a company, and consequently, to reduce debt cost. Prior studies were mainly conducted in developed, marketoriented economies, unlike Croatia. The contribution of this paper is the research of motives and determinants of asset revaluation policy choice in bank-oriented economies with inactive markets. Furthermore, multivariate logistic regression was not used as a research method in this field of accounting in transition and emerging economies till now. Empirical evidence is provided through the sample of Croatian listed companies and the results show that large, profitable companies with low liquidity ratio, low cash flow ratio and increasing debt are more likely to perform upward revaluation.

  8. Sampling Assumptions Affect Use of Indirect Negative Evidence in Language Learning.

    Directory of Open Access Journals (Sweden)

    Anne Hsu

    Full Text Available A classic debate in cognitive science revolves around understanding how children learn complex linguistic patterns, such as restrictions on verb alternations and contractions, without negative evidence. Recently, probabilistic models of language learning have been applied to this problem, framing it as a statistical inference from a random sample of sentences. These probabilistic models predict that learners should be sensitive to the way in which sentences are sampled. There are two main types of sampling assumptions that can operate in language learning: strong and weak sampling. Strong sampling, as assumed by probabilistic models, assumes the learning input is drawn from a distribution of grammatical samples from the underlying language and aims to learn this distribution. Thus, under strong sampling, the absence of a sentence construction from the input provides evidence that it has low or zero probability of grammaticality. Weak sampling does not make assumptions about the distribution from which the input is drawn, and thus the absence of a construction from the input as not used as evidence of its ungrammaticality. We demonstrate in a series of artificial language learning experiments that adults can produce behavior consistent with both sets of sampling assumptions, depending on how the learning problem is presented. These results suggest that people use information about the way in which linguistic input is sampled to guide their learning.

  11. Fiscal policy within a common currency area – growth implications in the light of neoclassical theory

    Directory of Open Access Journals (Sweden)

    Michał Konopczyński

    2013-10-01

    Full Text Available We examine the long-run impact of fiscal policy on economic growth under the conditions of an economic and monetary union (EMU. The analysis is based on the neoclassical growth model of a small (in economic terms open economy in an EMU. The core assumptions are perfect capital mobility, which results in identical interest rates across the EMU, and perfect mobility of goods, which leads to the convergence of price levels. The model is based on standard neoclassical assumptions, i.e., the output is determined by the Cobb-Douglas production function with a Harrod-neutral technical progress and constant returns to scale, capital and labor receive their marginal products, etc. We show that a unique long-run equilibrium exists and is characterized by the so-called natural rate of growth. The necessary and sufficient conditions of global asymptotic stability form a system of three non-trivial inequalities. We argue that in modern economies, these conditions are satisfied, except perhaps for very short periods of time. Furthermore, we show that the golden rules of fiscal policy have the form of an alternative optimal policy that crucially depends on the relation between the real interest rate and the natural rate of growth and on the relations between five other autonomous parameters.

  12. Debt Collection Models and Their Using in Practice

    Directory of Open Access Journals (Sweden)

    Anna Wodyńska

    2007-01-01

    Full Text Available An important element of a companys credit policy is its attitude to collecting due receivables. A company tries to establish the rules of collecting the said amount within the standards that are applied in a company. Depending on the organizational structure of a company, its scope of activity, common practices and, in particular, the credit policy assumed by a company, enterprises use internal, external or mixed debt collection models. Internal debt collection model assumes conducting debt collection activities within the organizational structure of a creditor company. External debt collection consists of ordering debt collection activities at a specialised company that handles debt service (outsourcing, which is connected with acting on behalf and account of the ordering party, but it also consists of receivables trading. The choice of proper debt collection model is not easy, due to, among others, high costs of the process as well as necessary expertise knowledge in the said scope; and the products offered on the market, although they seem similar, do differ substantially among one another. Regardless of the debt collection model, it shall be remembered that debt collection shall be run in a manner that ensures consolidation of entrepreneurs good name and their market position. The debt collection procedure binding in a company shall serve to work out a cooperation model with clients that are based on buyers reliability.

    The study aimed to investigate the scientific literature on Public Humanization Policies, available in online periodicals, from 2009 to 2012, in the health field. This is an integrative literature review conducted in the Virtual Health Library databases: Latin-America and Caribbean Health Sciences (Lilacs) and the Scientific Electronic Library Online (SciELO) and Portal Capes. Data were collected in July 2013. To this end, the following Health Sciences Descriptors (DeCS) were used: "Humanization of Care," "Public Policies," "National Humanization Policy". The sample consisted of 27 articles about the investigated theme. From the publications selected for the research, three categories emerged according to their respective approaches: National Human-ization Policy: history and processes involved in its implementation; National Humanization Policy: health professionals contribution; Humanization and in the care process. The study showed that the National Humanization Policy is an important benchmark in the development of health practices. For this reason, there is a pressing multiplication of related reflections on ways to promote human-ization in health services.

    2015-06-01

    In 2014 The Wellcome Library, part of the Wellcome Trust, introduced a new policy in order to address research access to personal data within its collections. The policy has now been used by library staff for almost a year. The policy was devised using a multi-stage approach which consisted of internal surveys and 1:1 interviews. Library staff can use the policy to guide decisions based on what level of access to award material donated or contributed to the Wellcome collections. The policy has been applied to 1 - a series of victorian medical photographs supplied by University Hospitals Bristol NHS Foundation Trust, and 2 - an album of family photographs from the collection of the psychiatrist Dr Ann Dally. Following almost a year in circulation the advantages and disadvantages can now be summarised.

  1. How Robust Refugee Protection Policies Can Strengthen Human and National Security

    Directory of Open Access Journals (Sweden)

    Donald Kerwin

    2016-09-01

    Full Text Available This paper makes the case that refugee protection and national security should be viewed as complementary, not conflicting state goals. It argues that refugee protection can further the security of refugees, affected states, and the international community. Refugees and international migrants can also advance national security by contributing to a state’s economic vitality, military strength, diplomatic standing, and civic values. The paper identifies several strategies that would, if implemented, promote both security and refugee protection. It also outlines additional steps that the US Congress should take to enhance US refugee protection policies and security. Finally, it argues for the efficacy of political engagement in support of pro-protection, pro-security policies, and against the assumption that political populism will invariably impede support for refugee protection.

  2. Semi-Supervised Transductive Hot Spot Predictor Working on Multiple Assumptions

    KAUST Repository

    Wang, Jim Jing-Yan

    2014-05-23

    Protein-protein interactions are critically dependent on just a few residues (“hot spots”) at the interfaces. Hot spots make a dominant contribution to the binding free energy and if mutated they can disrupt the interaction. As mutagenesis studies require significant experimental efforts, there exists a need for accurate and reliable computational hot spot prediction methods. Compared to the supervised hot spot prediction algorithms, the semi-supervised prediction methods can take into consideration both the labeled and unlabeled residues in the dataset during the prediction procedure. The transductive support vector machine has been utilized for this task and demonstrated a better prediction performance. To the best of our knowledge, however, none of the transductive semi-supervised algorithms takes all the three semisupervised assumptions, i.e., smoothness, cluster and manifold assumptions, together into account during learning. In this paper, we propose a novel semi-supervised method for hot spot residue prediction, by considering all the three semisupervised assumptions using nonlinear models. Our algorithm, IterPropMCS, works in an iterative manner. In each iteration, the algorithm first propagates the labels of the labeled residues to the unlabeled ones, along the shortest path between them on a graph, assuming that they lie on a nonlinear manifold. Then it selects the most confident residues as the labeled ones for the next iteration, according to the cluster and smoothness criteria, which is implemented by a nonlinear density estimator. Experiments on a benchmark dataset, using protein structure-based features, demonstrate that our approach is effective in predicting hot spots and compares favorably to other available methods. The results also show that our method outperforms the state-of-the-art transductive learning methods.

  4. Collectivity and statistics in deeply-inelastic heavy-ion collisions

    International Nuclear Information System (INIS)

    Spina, M.E.

    1983-01-01

    A model is developed to describe the transformation of relative kinetic energy into intrinsic excitation energy in DIC. Energy dissipation is viewed as an indirect process, in which collective vibrational modes are first excited coherently and then damped due to the coupling to the remaining non-collective degrees of freedom. Both collective and intrinsic degrees of freedom are included explicitly, and the coupling between them is treated in a Random Matrix Model. Under certain assumptions it is shown that, in the weak-coupling limit, the collective probability distribution in phase space obeys a Fokker-Plank equation. This transport equation is used to derive equations of motion for the expectation values of some ''macroscopic'' quantities characterizing the process. Some numerical results are presented and a qualitative comparison with the Copenhagen model is attempted. (orig.)

    Reynolds, Scott J; Leavitt, Keith; DeCelles, Katherine A

    2010-07-01

    We empirically examine the reflexive or automatic aspects of moral decision making. To begin, we develop and validate a measure of an individual's implicit assumption regarding the inherent morality of business. Then, using an in-basket exercise, we demonstrate that an implicit assumption that business is inherently moral impacts day-to-day business decisions and interacts with contextual cues to shape moral behavior. Ultimately, we offer evidence supporting a characterization of employees as reflexive interactionists: moral agents whose automatic decision-making processes interact with the environment to shape their moral behavior.

  8. A critical assessment of the ecological assumptions underpinning compensatory mitigation of salmon-derived nutrients

    Science.gov (United States)

    Collins, Scott F.; Marcarelli, Amy M.; Baxter, Colden V.; Wipfli, Mark S.

    2015-01-01

    We critically evaluate some of the key ecological assumptions underpinning the use of nutrient replacement as a means of recovering salmon populations and a range of other organisms thought to be linked to productive salmon runs. These assumptions include: (1) nutrient mitigation mimics the ecological roles of salmon, (2) mitigation is needed to replace salmon-derived nutrients and stimulate primary and invertebrate production in streams, and (3) food resources in rearing habitats limit populations of salmon and resident fishes. First, we call into question assumption one because an array of evidence points to the multi-faceted role played by spawning salmon, including disturbance via redd-building, nutrient recycling by live fish, and consumption by terrestrial consumers. Second, we show that assumption two may require qualification based upon a more complete understanding of nutrient cycling and productivity in streams. Third, we evaluate the empirical evidence supporting food limitation of fish populations and conclude it has been only weakly tested. On the basis of this assessment, we urge caution in the application of nutrient mitigation as a management tool. Although applications of nutrients and other materials intended to mitigate for lost or diminished runs of Pacific salmon may trigger ecological responses within treated ecosystems, contributions of these activities toward actual mitigation may be limited.

  10. Policy for Promotion of Women's Mental Health: Insight from Analysis of Policy on Postnatal Depression in Mexico.

    Science.gov (United States)

    Place, Jean Marie S; Billings, Deborah L; Frongillo, Edward A; Blake, Christine E; Mann, Joshua R; deCastro, Filipa

    2016-03-01

    This article critically examines federal, state and facility-level policies, as well as clinical practice guidelines regarding postnatal depression in Mexico. Thirteen documents including national health plans, national action plans, federal and state laws and regulations, clinical practice guidelines, and public-sector healthcare facility policies were collected and evaluated according to whether they included a statement of intent and/or actions related to the care of women at risk for or experiencing postnatal depression. While postnatal depression is included in several policies in Mexico, it is not addressed in ways that guide actions to manage postnatal depression. Specific direction on postnatal depression in policies would bridge a gap in maternal mental healthcare given that medication, treatment, and timing of interventions is unique in the postpartum context.

  11. ψ -ontology result without the Cartesian product assumption

    2018-05-01

    We introduce a weakening of the preparation independence postulate of Pusey et al. [Nat. Phys. 8, 475 (2012), 10.1038/nphys2309] that does not presuppose that the space of ontic states resulting from a product-state preparation can be represented by the Cartesian product of subsystem state spaces. On the basis of this weakened assumption, it is shown that, in any model that reproduces the quantum probabilities, any pair of pure quantum states |ψ >,|ϕ > with ≤1 /√{2 } must be ontologically distinct.

  12. Mathematical Model of (R,Q Inventory Policy under Limited Storage Space for Continuous and Periodic Review Policies with Backlog and Lost Sales

    Directory of Open Access Journals (Sweden)

    Kanokwan Singha

    2017-01-01

    Full Text Available This paper involves developing new mathematical expressions to find reorder point and order quantity for inventory management policies that explicitly consider storage space capacity. Both continuous and periodic reviews, as well as backlogged and lost demand during stockout, are considered. With storage space capacity, when on-hand inventory exceeds the capacity, the over-ordering cost of storage at an external warehouse is charged on a per-unit-period basis. The objective is to minimize the total cost, consisting of ordering, shortage, holding, and over-ordering costs. Demand and lead time are stochastic and discrete in nature. Demand during varying lead time is modeled using an empirical distribution so that the findings are not subject to assumptions of demand and lead time probability distributions. Due to the complexity of the developed mathematical expressions, the problems are solved using an iterative method. The method is tested with problem instances that use real data from industry. Optimal solutions of the problem instance are determined by performing exhaustive search. The proposed method can effectively find optimal solutions for continuous review policies and near optimal solutions for periodic review policies. Fundamental insights about the inventory policies are reported from a comparison between continuous review and periodic review solutions, as well as a comparison between backlog and lost sales cases.

  14. Drug policy constellations: A Habermasian approach for understanding English drug policy.

    Science.gov (United States)

    Stevens, Alex; Zampini, Giulia Federica

    2018-07-01

    It is increasingly accepted that a view of policy as a rational process of fitting evidence-based means to rationally justified ends is inadequate for understanding the actual processes of drug policy making. We aim to provide a better description and explanation of recent English drug policy decisions. We develop the policy constellation concept from the work of Habermas, in dialogue with data from two contemporary debates in English policy; on decriminalisation of drug possession and on recovery in drug treatment. We collect data on these debates through long-term participant observation, stakeholder interviews (n = 15) and documentary analysis. We show the importance of social asymmetries in power in enabling structurally advantaged groups to achieve the institutionalisation of their moral preferences as well as the reproduction of their social and economic power through the deployment of policies that reflect their material interests and normative beliefs. The most influential actors in English drug policy come together in a 'medico-penal constellation', in which the aims and practices of public health and social control overlap. Formal decriminalisation of possession has not occurred, despite the efforts of members of a challenging constellation which supports it. Recovery was put forward as the aim of drug treatment by members of a more powerfully connected constellation. It has been absorbed into the practice of 'recovery-oriented' drug treatment in a way that maintains the power of public health professionals to determine the form of treatment. Actors who share interests and norms come together in policy constellations. Strategic action within and between constellations creates policies that may not take the form that was intended by any individual actor. These policies do not result from purely rational deliberation, but are produced through 'systematically distorted communication'. They enable the most structurally favoured actors to institutionalise

    Full Text Available This paper examines three distinct periods of policy change and land redistribution in Ecuador through the agrarian reform laws of 1964, 1973 and 2010. A comparative case study of each moment of the law reforms was based on the instruments and policy network approach. In order to explain public policy process design, the high incidence of collective domains led by agribusiness on government management, and the incidence of indigenous organizations and farmers over the state action.

    Full Text Available Researchers, educators, policymakers, and other education stakeholders hope and anticipate that openness and open scholarship will generate positive outcomes for education and scholarship. Given the emerging nature of open practices, educators and scholars are finding themselves in a position in which they can shape and/or be shaped by openness. The intention of this paper is (a to identify the assumptions of the open scholarship movement and (b to highlight challenges associated with the movement’s aspirations of broadening access to education and knowledge. Through a critique of technology use in education, an understanding of educational technology narratives and their unfulfilled potential, and an appreciation of the negotiated implementation of technology use, we hope that this paper helps spark a conversation for a more critical, equitable, and effective future for education and open scholarship.

  17. World assumptions, posttraumatic stress and quality of life after a natural disaster: A longitudinal study

    Science.gov (United States)

    2012-01-01

    Background Changes in world assumptions are a fundamental concept within theories that explain posttraumatic stress disorder. The objective of the present study was to gain a greater understanding of how changes in world assumptions are related to quality of life and posttraumatic stress symptoms after a natural disaster. Methods A longitudinal study of 574 Norwegian adults who survived the Southeast Asian tsunami in 2004 was undertaken. Multilevel analyses were used to identify which factors at six months post-tsunami predicted quality of life and posttraumatic stress symptoms two years post-tsunami. Results Good quality of life and posttraumatic stress symptoms were negatively related. However, major differences in the predictors of these outcomes were found. Females reported significantly higher quality of life and more posttraumatic stress than men. The association between level of exposure to the tsunami and quality of life seemed to be mediated by posttraumatic stress. Negative perceived changes in the assumption “the world is just” were related to adverse outcome in both quality of life and posttraumatic stress. Positive perceived changes in the assumptions “life is meaningful” and “feeling that I am a valuable human” were associated with higher levels of quality of life but not with posttraumatic stress. Conclusions Quality of life and posttraumatic stress symptoms demonstrate differences in their etiology. World assumptions may be less specifically related to posttraumatic stress than has been postulated in some cognitive theories. PMID:22742447

    1994-01-01

    The U.S. Department of Energy is considering a broad range of alternatives for the future configuration of radioactive waste management at its network of facilities. Because the transportation of radioactive waste is an integral component of the management alternatives being considered, the estimated human health risks associated with both routine and accident transportation conditions must be assessed to allow a complete appraisal of the alternatives. This paper provides an overview of the technical approach being used to assess the radiological risks from the transportation of radioactive wastes. The approach presented employs the RADTRAN 4 computer code to estimate the collective population risk during routine and accident transportation conditions. Supplemental analyses are conducted using the RISKIND computer code to address areas of specific concern to individuals or population subgroups. RISKIND is used for estimating routine doses to maximally exposed individuals and for assessing the consequences of the most severe credible transportation accidents. The transportation risk assessment is designed to ensure -- through uniform and judicious selection of models, data, and assumptions -- that relative comparisons of risk among the various alternatives are meaningful. This is accomplished by uniformly applying common input parameters and assumptions to each waste type for all alternatives. The approach presented can be applied to all radioactive waste types and provides a consistent and comprehensive evaluation of transportation-related risk

  19. Harmonisation of European Migration Policies: The Failure of Immigration Control Policies in the Seventh and Eighth Decades of the 20th Century

    Directory of Open Access Journals (Sweden)

    2003-12-01

    Full Text Available Until the middle of the 1970s, the migration policies of developed European countries were based on the assumption that controlling immigration was possible. Due to various reasons discussed in this article, such policies proved unsuccessful. The result was an increase in the total number of foreigners and a change in the composition of immigrant communities, i.e. the proportion of supported family members increased. During the 1980s there was increasing convergence in the migration policies of European immigration countries and traditional overseas emigration countries. Policies were more and more oriented towards preventing illegal migration flows, on regulating refugee flows and on balancing labour migration with family migration. The turning-point in the direction of “harmonising” West European migration policies was marked by the Schengen agreement (1985 on gradual elimination of border controls between the signing parties (France, Germany and the Benelux countries. Fear in the face of a possible invasion of Eastern Europeans after the collapse of socialism in 1989 was a further strong stimulus towards the harmonisation of migration policies in the developing EU. As opposed to migration control, the integration of immigrants has remained so far the prerogative of nation-states. The text further presents an overview of migration policy reforms in individual member states of the EU and of multilateral actions. The post-1989 migration regime in Europe has four major traits: 1 an extension of the agenda; 2 an accent on joint actions; 3 defensiveness; 4 confusion and an overload of issues. While on the one hand the EU continues to seek ways of protecting itself from undesired external migration, on the other hand the process of regional integration continues to “erase” its internal borders.

  20. The retirement cliff: Power plant lives and their policy implications

    2017-01-01

    This paper examines more than a century of U.S. power plant additions and retirements in conjunction with several decades of utility capital investment data. While policy analyses often invoke assumptions of power plant book life, relatively little analysis has focused on the physical life of power-generating assets. The average age of the U.S. generator fleet has increased significantly over time despite continued investment, in part because more recent investment has tended to focus on shorter-lived assets. This may be due in part to risk-averse power sector investors and lenders responding rationally to regulatory uncertainty in a deregulated market environment. Power plant retirement trends suggest that the pace of retirements will increase significantly in the decade after 2030 for most reasonable estimates of physical life. These capital investment trends have important consequences for carbon policy and highlight the importance of including consideration of the longer term—particularly when evaluating more significant decarbonization policies. - Highlights: • Many policy analyses neglect the physical lives of power plants. • A large database of U.S. power plant additions and retirements is examined. • The average age of power plants has steadily increased despite growing investment. • Long-term CO 2 reduction strategies are challenged by increases in plant retirements.

  1. Oil production, oil prices, and macroeconomic adjustment under different wage assumptions

    International Nuclear Information System (INIS)

    1992-01-01

    In a previous paper one of the authors developed a simple model to try to identify the possible macroeconomic adjustment processes arising in an economy experiencing a temporary period of oil production, under alternative wage adjustment assumptions, namely nominal and real wage rigidity. Certain assumptions were made regarding the characteristics of actual production, the permanent revenues generated from that oil production, and the net exports/imports of oil. The role of the price of oil, and possible changes in that price was essentially ignored. Here we attempt to incorporate the price of oil, as well as changes in that price, in conjunction with the production of oil, the objective being to identify the contribution which the price of oil, and changes in it, make to the adjustment process itself. The emphasis in this paper is not given to a mathematical derivation and analysis of the model's dynamics of adjustment or its comparative statics, but rather to the derivation of simulation results from the model, for a specific assumed case, using a numerical algorithm program, conducive to the type of theoretical framework utilized here. The results presented suggest that although the adjustment profiles of the macroeconomic variables of interest, for either wage adjustment assumption, remain fundamentally the same, the magnitude of these adjustments is increased. Hence to derive a more accurate picture of the dimensions of adjustment of these macroeconomic variables, it is essential to include the price of oil as well as changes in that price. (Author)

  3. Energy production, distribution, and pollution controls: Combining engineering and economic analysis to enhance efficiency and policy design

    Science.gov (United States)

    Perkis, David F.

    Three published articles are presented which focus on enhancing various aspects of the energy supply chain. While each paper adopts a different methodology, all three combine engineering data and/or techniques with economic analysis to improve efficiency or policy design within energy markets. The first paper combines a chemical engineering plant design model with an economic assessment of product enhancements within an ethanol production facility. While a new chemical process is shown to achieve greater ethanol yields, the animal feed by-products are denatured and decrease in value due to the degradation of a key nutritional amino acid. Overall, yield increases outweigh any costs, providing additional value to firms adopting this process. The second paper uses a mixed integer linear model to assess the optimal location of cellulosic ethanol production facilities within the state of Indiana. Desired locations with low costs are linked to regions with high yield corn growth, as these areas provide an abundance of corn stover, a by-product of corn and a cellulosic source of ethanol. The third paper implements experimental economic methods to assess the effectiveness of policies intended to control prices in emissions permit markets. When utilizing reserve permit auctions as an alternative to setting explicit maximum prices, prices are elevated beyond the theoretical predictions of the model within the conditions of the experiment. The most likely cause of higher prices is the negotiating power provided to sellers by grandfathering permits as evidenced by higher than expected welfare gains to sellers. Before presenting the articles, a discussion is introduced regarding the role of assumptions used by economists. For each article, a key assumption is highlighted and the consequences of making a different assumption are provided. Whether the consequences are large or small, the benefits of elucidating our models with assumptions based on real world behaviors are clearly

    Despite attempts, policy silences continue to create barriers to addressing the healthcare needs of First Nations, Inuit and Métis. The purpose of this article is to answer the question, if what we have in Canada is an Aboriginal health policy patchwork that fails to address inequities, then what would a Healthy Aboriginal Health Policy framework look like? The data collected included federal, provincial and territorial health policies and legislation that contain Aboriginal, First Nation, Inuit and/or Métis-specific provisions available on the internet. Key websites included the Parliamentary Library, federal, provincial and territorial health and Aboriginal websites, as well as the Department of Justice Canada, Statistics Canada and the Aboriginal Canada Portal. The Indian Act gives the Governor in Council the authority to make health regulations. The First Nations and Inuit Health Branch (FNIHB) of Health Canada historically provided health services to First Nations and Inuit, as a matter of policy. FNIHB's policies are few, and apply only to Status Indians and Inuit. Health legislation in 2 territories and 4 provinces contain no provision to clarify their responsibilities. In provinces where provisions exist, they broadly focus on jurisdiction. Few Aboriginal-specific policies and policy frameworks exist. Generally, these apply to some Aboriginal peoples and exclude others. Although some Aboriginal-specific provisions exist in some legislation, and some policies are in place, significant gaps and jurisdictional ambiguities remain. This policy patchwork perpetuates confusion. A national First Nation, Inuit and Métis policy framework is needed to address this issue.

    Full Text Available This book investigates how culture, particularly national culture, in Indonesia has been shaped by the government policies from the Dutch colonial period in 1900s to the Reformation era in 2000s. It is an attempt to show the relationship between the state and culture around the process of production, circulation, regulation and reception of cultural policy through different regimes. Although this book discusses government policy, the author has realized that the book needs to overcome contradictions and confusions of cultural discourse by incorporating people as explanatory element. Many aspect of culturality may be influenced by the state, but according to Jones, “it is a field that is not stable and easy to shift that facilitates resistance, and is able to turn against the state, market and other institutions” (p. 31. Jones employs two postcolonial cultural policy tools to review the history of cultural policy in Indonesia: authoritarian cultural policy and command culture. The first means that the state has assumption if majority of citizen do not have capability to inspirit a responsible citizenship and need a state’s direction in the choice of their culture. On the contrary, command culture shows that the cultural idea that is planned in fact always been placing the state as center in planning, creating policy and revising cultural practice.

    Determining the most probable cause of death is important, and it is sometimes tempting to assume an obvious cause of death, when it readily presents itself, and stop looking for other competing causes of death. The case story presented in the article illustrates this dilemma. The first assumption...... of cause of death, which was based on results from bacteriology tests, proved to be wrong when the results from the forensic toxicology testing became available. This case also illustrates how post mortem computed tomography (PMCT) findings of radio opaque material in the stomach alerted the pathologist...

    Current radiation protection standards are based upon the application of the linear no-threshold (LNT) assumption, which considers that even very low doses of ionizing radiation can cause cancer. The radiation hormesis hypothesis, by contrast, proposes that low-dose ionizing radiation is beneficial. In this book, the author examines all facets of radiation hormesis in detail, including the history of the concept and mechanisms, and presents comprehensive, up-to-date reviews for major cancer types. It is explained how low-dose radiation can in fact decrease all-cause and all-cancer mortality an

    This paper describes the objectives and approach to the climate policy impact analysis on the development of energy sector. The analysis included the goals for CO2 emission reduction until 2050, by sectors and in total, with reference to last 5-10 years. The analysis of energy market development in terms of CO2 emission reduction is given, and also the analysis of the final consumption for Croatia in period until 2050. The analysis of measures, of the manner in which the measures are carried out and of the potential of measures for CO2 emission reduction is presented. Estimations of economic and financial indicators for measurement implementation are given. Technological, energy, economic, organizational and institutional limitations are specifically analysed as part of objectives realisation of CO2 emission reduction, as is the risk of measurement implementation. The important parts of CO2 emission reduction policy are: technological development, expectations and possible risks of not achieving the set objectives. The important assumption of CO2 emission reduction objective realisation is institutional organisation of creation of energy policy and measurement implementation, in which the important measure is the forming of Ministry of energy, environment protection and climate change. At the end, recommendations are given, based on the performed analysis. (author).

  13. The Impact of the Great Recession on Monetary and Fiscal Policy in Developed Market Economies

    2015-03-01

    Full Text Available Background: With the occurrence of the crisis in 2007, which caused the largest economic contraction since the Great Depression in the thirties, it has become evident that the previous understanding of strategies, effects and roles of monetary and fiscal policy should be redefined. Objectives: The aim of this paper is to illustrate a possible expected change in monetary and fiscal policy in developed market economies that could occur as a consequence of the Great Recession. Methods/Approach: The paper provides a comparative analysis of various primary economic variables related to the developed OECD countries, as well as the empirical testing of the selected theoretical assumptions. Results: The changes in monetary policy refer to the question of raising target inflation, considering a possible use of aggregate price level targeting and paying attention to the role of central banks in suppressing the formation of an asset bubble. The success of fiscal policy in attaining stabilization depends on the size of possible fiscal measures and creation of automatic stabilizers. Conclusions: For the most part, monetary and fiscal policies will still stay unchanged, although some segments of these policies need to be improved.

  15. Investigating Darcy-scale assumptions by means of a multiphysics algorithm

    Tomin, Pavel; Lunati, Ivan

    2016-09-01

    Multiphysics (or hybrid) algorithms, which couple Darcy and pore-scale descriptions of flow through porous media in a single numerical framework, are usually employed to decrease the computational cost of full pore-scale simulations or to increase the accuracy of pure Darcy-scale simulations when a simple macroscopic description breaks down. Despite the massive increase in available computational power, the application of these techniques remains limited to core-size problems and upscaling remains crucial for practical large-scale applications. In this context, the Hybrid Multiscale Finite Volume (HMsFV) method, which constructs the macroscopic (Darcy-scale) problem directly by numerical averaging of pore-scale flow, offers not only a flexible framework to efficiently deal with multiphysics problems, but also a tool to investigate the assumptions used to derive macroscopic models and to better understand the relationship between pore-scale quantities and the corresponding macroscale variables. Indeed, by direct comparison of the multiphysics solution with a reference pore-scale simulation, we can assess the validity of the closure assumptions inherent to the multiphysics algorithm and infer the consequences for macroscopic models at the Darcy scale. We show that the definition of the scale ratio based on the geometric properties of the porous medium is well justified only for single-phase flow, whereas in case of unstable multiphase flow the nonlinear interplay between different forces creates complex fluid patterns characterized by new spatial scales, which emerge dynamically and weaken the scale-separation assumption. In general, the multiphysics solution proves very robust even when the characteristic size of the fluid-distribution patterns is comparable with the observation length, provided that all relevant physical processes affecting the fluid distribution are considered. This suggests that macroscopic constitutive relationships (e.g., the relative

    Bushmeat management policies are often developed outside the communities in which they are to be implemented. These policies are also routinely designed to be applied uniformly across communities with little regard for variation in social or ecological conditions. We used fuzzy-logic cognitive mapping, a form of participatory modeling, to compare the assumptions driving externally generated bushmeat management policies with perceptions of bushmeat trade dynamics collected from local community members who admitted to being recently engaged in bushmeat trading (e.g., hunters, sellers, consumers). Data were collected during 9 workshops in 4 Tanzanian villages bordering Serengeti National Park. Specifically, we evaluated 9 community-generated models for the presence of the central factors that comprise and drive the bushmeat trade and whether or not models included the same core concepts, relationships, and logical chains of reasoning on which bushmeat conservation policies are commonly based. Across local communities, there was agreement about the most central factors important to understanding the bushmeat trade (e.g., animal recruitment, low income, and scarcity of food crops). These matched policy assumptions. However, the factors perceived to drive social-ecological bushmeat trade dynamics were more diverse and varied considerably across communities (e.g., presence or absence of collaborative law enforcement, increasing human population, market demand, cultural preference). Sensitive conservation issues, such as the bushmeat trade, that require cooperation between communities and outside conservation organizations can benefit from participatory modeling approaches that make local-scale dynamics and conservation policy assumptions explicit. Further, communities' and conservation organizations' perceptions need to be aligned. This can improve success by allowing context appropriate policies to be developed, monitored, and appropriately adapted as new evidence is

  18. Basic concepts and assumptions behind the new ICRP recommendations

    Lindell, B.

    1979-01-01

    A review is given of some of the basic concepts and assumptions behind the current recommendations by the International Commission on Radiological Protection in ICRP Publications 26 and 28, which form the basis for the revision of the Basic Safety Standards jointly undertaken by IAEA, ILO, NEA and WHO. Special attention is given to the assumption of a linear, non-threshold dose-response relationship for stochastic radiation effects such as cancer and hereditary harm. The three basic principles of protection are discussed: justification of practice, optimization of protection and individual risk limitation. In the new ICRP recommendations particular emphasis is given to the principle of keeping all radiation doses as low as is reasonably achievable. A consequence of this is that the ICRP dose limits are now given as boundary conditions for the justification and optimization procedures rather than as values that should be used for purposes of planning and design. The fractional increase in total risk at various ages after continuous exposure near the dose limits is given as an illustration. The need for taking other sources, present and future, into account when applying the dose limits leads to the use of the commitment concept. This is briefly discussed as well as the new quantity, the effective dose equivalent, introduced by ICRP. (author)

    For a number of years, analyses of minority household energy demand have been supported by the United States Department of Energy (DOE), Office of Economic Impact and Diversity (formerly the Office of Minority Economic Impact). The intention of these analyses has been to characterize patterns of energy demand by various demographic, regional and socioeconomic groups and to develop analytical tools to assess the distributive impact of energy prices and policy on these groups. The model supports strategic objectives outlined by the Department of Energy to explicitly recognize and promote equity in state public utility commission decisions and to assess the potential impact of federal and state energy policy on demographically diverse groups as reported in the Department`s Annual Energy Outlook and the upcoming National Energy Policy Plan. The legislation mandating the Office of Economic Impact and Diversity had been premised on the assumption that patterns of energy demand for minority households are different from the population as a whole. Determining the validity of this premise and its potential economic impact on different population groups has been a major objective of these analyses. Consequently, the recripriocal impacts of energy policy on demographic groups and energy consumption and expenditure dynamics on policy formulation and strategy is a central objective of these studies. Residential energy demand research has been substantial in the past twenty years. Insightful and useful research has been done in this area. However, none of this research has addressed the potential differences in the residential energy demand structure among various population groups. Recent work does compare energy and electricity demand elasticities for non-Latino Whites, with the demand elasticities for Latinos and Blacks. This research is particularly important for examination of questions related to the economic welfare implications of national energy policy.

  20. Has the "Equal Environments" assumption been tested in twin studies?

    Science.gov (United States)

    Eaves, Lindon; Foley, Debra; Silberg, Judy

    2003-12-01

    A recurring criticism of the twin method for quantifying genetic and environmental components of human differences is the necessity of the so-called "equal environments assumption" (EEA) (i.e., that monozygotic and dizygotic twins experience equally correlated environments). It has been proposed to test the EEA by stratifying twin correlations by indices of the amount of shared environment. However, relevant environments may also be influenced by genetic differences. We present a model for the role of genetic factors in niche selection by twins that may account for variation in indices of the shared twin environment (e.g., contact between members of twin pairs). Simulations reveal that stratification of twin correlations by amount of contact can yield spurious evidence of large shared environmental effects in some strata and even give false indications of genotype x environment interaction. The stratification approach to testing the equal environments assumption may be misleading and the results of such tests may actually be consistent with a simpler theory of the role of genetic factors in niche selection.

    Thanks to the availability of open-source software, online tutorials, and advanced software capabilities, watershed modeling has expanded its user-base and applications significantly in the past thirty years. Even complicated models like the Soil and Water Assessment Tool (SWAT) are being used and documented in hundreds of peer-reviewed publications each year, and likely more applied in practice. These models can help improve our understanding of present, past, and future conditions, or analyze important "what-if" management scenarios. However, baseline data and methods are often adopted and applied without rigorous testing. In multiple collaborative projects, we have evaluated the influence of some of these common approaches on model results. Specifically, we examined impacts of baseline data and assumptions involved in manure application, combined sewer overflows, and climate data incorporation across multiple watersheds in the Western Lake Erie Basin. In these efforts, we seek to understand the impact of using typical modeling data and assumptions, versus using improved data and enhanced assumptions on model outcomes and thus ultimately, study conclusions. We provide guidance for modelers as they adopt and apply data and models for their specific study region. While it is difficult to quantitatively assess the full uncertainty surrounding model input data and assumptions, recognizing the impacts of model input choices is important when considering actions at the both the field and watershed scales.

    In the present project the market scenario for analysing market imperfections has been the Northern European power market, i.e. a market including Germany as well. Consequently, one of the tasks in the project has been to collect data for Germany in order to develop the empirical basis of the ELEPHANT model. In that perspective the aim of this report is to document the data collected for Gemany, to specify the data sources used and further to lay stress on the assumptions which have been made when data have not been available. By doing so, transparency in model results is improved. Further, a basis for discussing the quality of data as well as a framework for future revisions and updating of data have been established. The data collected for Germany have been given by the exogenous variables defined by the ELEPHANT model. In that way data collection is a priori given by the specification of the model. The model includes more than 30 exogenous variables specified at a very detailed level. These variables include among others data on energy demand, detailed power production data and data on energy taxes and CO{sub 2} emission targets. This points to the fact that many kinds of data sources have been used. However, due to lack of data sources not all relevant data have been collected. One area in which lack of data has been significant is demand reactions to changes in energy prices, i.e. the different kinds of demand elasticities used in the production and consumer utility functions in the model.

    2013-01-01

    The SunShot Vision Study explored the potential growth of solar markets if solar prices decreased by about 75% from 2010 to 2020. The SolarDS model was used to simulate rooftop PV demand for this study, based on several PV market assumptions--future electricity rates, customer access to financing, and others--in addition to the SunShot PV price projections. This paper finds that modeled PV demand is highly sensitive to several non-price market assumptions, particularly PV financing parameters.

    Carbon payments can help mitigate both climate change and biodiversity decline through the reforestation of agricultural land. However, to achieve biodiversity co-benefits, carbon payments often require support from other policy mechanisms such as regulation, targeting, and complementary incentives. We evaluated 14 policy mechanisms for supplying carbon and biodiversity co-benefits through reforestation of carbon plantings (CP) and environmental plantings (EP) in Australia’s 85.3 Mha agricultural land under global change. The reference policy--uniform payments (bidders are paid the same price) with land-use competition (both CP and EP eligible for payments), targeting carbon--achieved significant carbon sequestration but negligible biodiversity co-benefits. Land-use regulation (only EP eligible) and two additional incentives complementing the reference policy (biodiversity premium, carbon levy) increased biodiversity co-benefits, but mostly inefficiently. Discriminatory payments (bidders are paid their bid price) with land-use competition were efficient, and with multifunctional targeting of both carbon and biodiversity co-benefits increased the biodiversity co-benefits almost 100-fold. Our findings were robust to uncertainty in global outlook, and to key agricultural productivity and land-use adoption assumptions. The results suggest clear policy directions, but careful mechanism design will be key to realising these efficiencies in practice. Choices remain for society about the amount of carbon and biodiversity co-benefits desired, and the price it is prepared to pay for them.

    As the emphasis on preventing obesity has grown, so have calls for interventions that extend beyond individual behaviors and address changes in environments and policies. Despite the need for policy action, little is known about policy approaches that are most effective at preventing obesity. The Centers for Disease Control and Prevention (CDC) and others are funding the implementation and evaluation of new obesity prevention policies, presenting a distinct opportunity to learn from these practice-based initiatives and build the body of evidence-based approaches. However, contributions from this policy activity are limited by the incomplete and inconsistent evaluation data collected on policy processes and outcomes. We present a framework developed by the CDC-funded Center of Excellence for Training and Research Translation that public health practitioners can use to evaluate policy interventions and identify the practice-based evidence needed to fill the gaps in effective policy approaches to obesity prevention.

    Aim To examine assumptions about public-private partnership (PPP) activities and their role in improving public procurement of primary healthcare surgeries. PPPs were developed to improve the quality of care and patient satisfaction. However, evidence of their effectiveness in delivering health benefits is limited. A qualitative study design was employed. A total of 25 interviews with public sector staff (n=23) and private sector managers (n=2) were conducted to understand their interpretations of assumptions in the activities of private investors and service contractors participating in Local Improvement Finance Trust (LIFT) partnerships. Realist evaluation principles were applied in the data analysis to interpret the findings. Six thematic areas of assumed health benefits were identified: (i) quality improvement; (ii) improved risk management; (iii) reduced procurement costs; (iv) increased efficiency; (v) community involvement; and (vi) sustainable investment. Primary Care Trusts that chose to procure their surgeries through LIFT were expected to support its implementation by providing an environment conducive for the private participants to achieve these benefits. Private participant activities were found to be based on a range of explicit and tacit assumptions perceived helpful in achieving government objectives for LIFT. The success of PPPs depended upon private participants' (i) capacity to assess how PPP assumptions added value to their activities, (ii) effectiveness in interpreting assumptions in their expected activities, and (iii) preparedness to align their business principles to government objectives for PPPs. They risked missing some of the expected benefits because of some factors constraining realization of the assumptions. The ways in which private participants preferred to carry out their activities also influenced the extent to which expected benefits were achieved. Giving more discretion to public than private participants over critical

    2017-01-01

    Linear approximations of the Generalized Almost Ideal Demand System and Almost Ideal Demand System for U.S. energy are compared to contrast the explicit inclusion and exclusion of pre-committed consumption levels. Results indicate that pre-commitment levels, the quantity of a good that is consumed in the short run with little regard for price, helps to better explain energy demand in the U.S. compared to the system that does not explicitly consider pre-commitments. Policy implications are if pre-commitments are a legitimate assumption, larger price changes are necessary to achieve a given policy objective than if there are no pre-commitments. - Highlights: • Pre-commitments are the quantity that is consumed with little regard for price. • Demand systems with pre-commitment levels better explain energy demand. • Elasticities from assuming pre-commitments are more elastic. • Estimated elasticities apply to discretionary and not pre-commitment consumption. • Pre-commitments require larger price changes to achieve a given policy objective.

  16. Optimal replacement policy of products with repair-cost threshold after the extended warranty

    Lijun Shang; Zhiqiang Cai

    2017-01-01

    The reliability of the product sold under a warranty is usually maintained by the manufacturer during the warranty period. After the expiry of the warranty, however, the consumer confronts a problem about how to maintain the reliability of the product. This paper proposes, from the consumer's perspective, a replace-ment policy after the extended warranty, under the assumption that the product is sold under the renewable free replacement warranty (RFRW) policy in which the replacement is dependent on the repair-cost threshold. The proposed replacement policy is the replacement after the extended warranty is performed by the consumer based on the repair-cost threshold or preventive replacement (PR) age, which are decision variables. The expected cost rate model is derived from the consumer's perspective. The existence and uniqueness of the optimal solution that minimizes the expected cost rate per unit time are offered. Finally, a numeri-cal example is presented to exemplify the proposed model.

  18. Examination of Conservatism in Ground-level Source Release Assumption when Performing Consequence Analysis

    One of these assumptions frequently assumed is the assumption of ground-level source release. The user manual of a consequence analysis software HotSpot is mentioning like below: 'If you cannot estimate or calculate the effective release height, the actual physical release height (height of the stack) or zero for ground-level release should be used. This will usually yield a conservative estimate, (i.e., larger radiation doses for all downwind receptors, etc).' This recommendation could be agreed in aspect of conservatism but quantitative examination of the effect of this assumption to the result of consequence analysis is necessary. The source terms of Fukushima Dai-ichi NPP accident have been estimated by several studies using inverse modeling and one of the biggest sources of the difference between the results of these studies was different effective source release height assumed by each studies. It supports the importance of the quantitative examination of the influence by release height. Sensitivity analysis of the effective release height of radioactive sources was performed and the influence to the total effective dose was quantitatively examined in this study. Above 20% difference is maintained even at longer distances, when we compare the dose between the result assuming ground-level release and the results assuming other effective plume height. It means that we cannot ignore the influence of ground-level source assumption to the latent cancer fatality estimations. In addition, the assumption of ground-level release fundamentally prevents detailed analysis including diffusion of plume from effective plume height to the ground even though the influence of it is relatively lower in longer distance. When we additionally consider the influence of surface roughness, situations could be more serious. The ground level dose could be highly over-estimated in short downwind distance at the NPP sites which have low surface roughness such as Barakah site in

  19. Legislating thresholds for drug trafficking: a policy development case study from New South Wales, Australia.

    2014-09-01

    Legal thresholds are used in many parts of the world to define the quantity of illicit drugs over which possession is deemed "trafficking" as opposed to "possession for personal use". There is limited knowledge about why or how such laws were developed. In this study we analyse the policy processes underpinning the introduction and expansion of the drug trafficking legal threshold system in New South Wales (NSW), Australia. A critical legal and historical analysis was undertaken sourcing data from legislation, Parliamentary Hansard debates, government inquiries, police reports and research. A timeline of policy developments was constructed from 1970 until 2013 outlining key steps including threshold introduction (1970), expansion (1985), and wholesale revision (1988). We then critically analysed the drivers of each step and the roles played by formal policy actors, public opinion, research/data and the drug trafficking problem. We find evidence that while justified as a necessary tool for effective law enforcement of drug trafficking, their introduction largely preceded overt police calls for reform or actual increases in drug trafficking. Moreover, while the expansion from one to four thresholds had the intent of differentiating small from large scale traffickers, the quantities employed were based on government assumptions which led to "manifest problems" and the revision in 1988 of over 100 different quantities. Despite the revisions, there has remained no further formal review and new quantities for "legal highs" continue to be added based on assumption and an uncertain evidence-base. The development of legal thresholds for drug trafficking in NSW has been arbitrary and messy. That the arbitrariness persists from 1970 until the present day makes it hard to conclude the thresholds have been well designed. Our narrative provides a platform for future policy reform.

  2. Dynamic analysis of policy drivers for bioenergy commodity markets

    International Nuclear Information System (INIS)

    Jeffers, Robert F.; Jacobson, Jacob J.; Searcy, Erin M.

    2013-01-01

    Biomass is increasingly being considered as a feedstock to provide a clean and renewable source of energy in the form of both liquid fuels and electric power. In the United States, the biofuels and biopower industries are regulated by different policies and have different drivers, which impact the maximum price the industries are willing to pay for biomass. This article describes a dynamic computer simulation model that analyzes future behavior of bioenergy feedstock markets given policy and technical options. The model simulates the long-term dynamics of these markets by treating advanced biomass feedstocks as a commodity and projecting the total demand of each industry, as well as the market price over time. The model is used for an analysis of the United States bioenergy feedstock market that projects supply, demand, and market price given three independent buyers: domestic biopower, domestic biofuels, and foreign exports. With base-case assumptions, the biofuels industry is able to dominate the market and meet the federal Renewable Fuel Standard (RFS) targets for advanced biofuels. Further analyses suggest that United States bioenergy studies should include estimates of export demand in their projections, and that GHG-limiting policy would partially shield both industries from export dominance. - Highlights: ► We model a United States bioenergy feedstock commodity market. ► Three buyers compete for biomass: biopower, biofuels, and foreign exports. ► The presented methodology improves on dynamic economic equilibrium theory. ► With current policy incentives and ignoring exports, biofuels dominates the market. ► Overseas biomass demand could dominate unless a CO 2 -limiting policy is enacted.

    Byung Duk Song

    2017-09-01

    Full Text Available In the green manufacturing system that pursues the reuse of used products, the residual value of collected used products (CUP hugely affects a variety of managerial decisions to construct profitable and environmental remanufacturing plans. This paper deals with a closed-loop green manufacturing system for companies which perform both manufacturing with raw materials and remanufacturing with collected used products (CUP. The amount of CUP is assumed as a function of buy-back cost while the quality level of CUP, which means the residual value, follows a known distribution. In addition, the remanufacturing cost can differ according to the quality of the CUP. Moreover, nowadays companies are subject to existing environment-related laws such as Extended Producer Responsibility (EPR. Therefore, a company should collect more used products than its obligatory take-back quota or face fines from the government for not meeting its quota. Through the development of mathematical models, two kinds of inspection policies are examined to validate the efficiency of two different operation processes. To find a managerial solution, a genetic algorithm is proposed and tested with numerical examples.

    The SESPIR Project (Epidemiological Surveillance of Health Status of Resident Population Around the Waste Treatment Plants) assessed the impact on health of residents nearby incinerators, landfills and mechanical biological treatment plants in five Italian regions (Emilia-Romagna, Piedmont, Lazio, Campania, and Sicily). The assessment procedure took into account the available knowledge on health effects of waste disposal facilities. Analyses were related to three different scenarios: a Baseline scenario, referred to plants active in 2008-2009; the regional future scenario, with plants expected in the waste regional plans; a virtuous scenario (Green 2020), based on a policy management of municipal solid waste (MSW) through the reduction of production and an intense recovery policy. Facing with a total population of around 24 million for the 5 regions, the residents nearby the plants were more than 380,000 people at Baseline. Such a population is reduced to approximately 330.000 inhabitants and 170.000 inhabitants in the regional and Green 2020 scenarios, respectively. The health impact was assessed for the period 2008-2040. At Baseline, 1-2 cases per year of cancer attributable to MSW plants were estimated, as well as 26 cases per year of adverse pregnancy outcomes (including low birth weight and birth defects), 102 persons with respiratory symptoms, and about a thousand affected from annoyance caused by odours. These annual estimates are translated into 2,725 years of life with disability (DALYs) estimated for the entire period. The DALYs are reduced by approximately 20% and 80% in the two future scenarios. Even in these cases, health impact is given by the greater effects on pregnancy and the annoyance associated with the odours of plants. In spite of the limitations due to the inevitable assumptions required by the present exercise, the proposed methodology is suitable for a first approach to assess different policies that can be adopted in regional planning in

    2016-01-01

    The political line in Swedish disability policy advocates the use of generalized solutions in order to fit potential needs of the largest possible group of people and, where needed, special solutions to bridge the remaining gap between the generalized level of accessibility and additional individual needs. This is referred to as the disability perspective (DP). The DP has embraced two tracks: one that pertains to generalized solutions that promote an overall high level of accessibility and usability, and another one that pertains to different types of individual support for people with disabilities. The present study is a self-reflective inquiry on key issues for the development of future disability policies. Five experts entered a discussion about the pros and cons concerning the DP. This confirmed or refuted assumptions, dilemmas, themes as well as reoccurring patterns in the political viva voce procedure that has formed the contemporary disability policy. Over the course of time, the experts believed that the DP had nurtured a belief that there is a dichotomy. This may have created an imbalance in the relation between the DP and policies such as those concerning healthcare and social care. With a clearer focus on interdependence, the experts saw synergies between needs for assistive technology, assistive products and the requirements for the built environment.

    Health policy papers disseminate recommendations and guidelines for the development and implementation of health promotion interventions. Such documents have rarely been investigated with regard to their assumed mechanisms of action for changing behaviour. The Theoretical Domains Framework (TDF) and Behaviour Change Techniques (BCT) Taxonomy have been used to code behaviour change intervention descriptions, but to our knowledge such "retrofitting" of policy papers has not previously been reported. This study aims first to identify targets, mediators, and change strategies for physical activity (PA) and nutrition behaviour change in Finnish policy papers on workplace health promotion, and second to assess the suitability of the Behaviour Change Wheel (BCW) approach for this purpose. We searched all national-level health policy papers effectual in Finland in August 2016 focusing on the promotion of PA and/or healthy nutrition in the workplace context (n = 6). Policy recommendations targeting employees' nutrition and PA including sedentary behaviour (SB) were coded using BCW, TDF, and BCT Taxonomy. A total of 125 recommendations were coded in the six policy papers, and in two additional documents referenced by them. Psychological capability, physical opportunity, and social opportunity were frequently identified (22%, 31%, and 24%, respectively), whereas physical capability was almost completely absent (1%). Three TDF domains (knowledge, skills, and social influence) were observed in all papers. Multiple intervention functions and BCTs were identified in all papers but several recommendations were too vague to be coded reliably. Influencing individuals (46%) and changing the physical environment (44%) were recommended more frequently than influencing the social environment (10%). The BCW approach appeared to be useful for analysing the content of health policy papers. Paying more attention to underlying assumptions regarding behavioural change processes may help to

Forensic chemical methods can be powerful tools in source characterization and identification, but they require a multiple-lines-of-evidence approach. Atmospheric receptor models, such as the US Environmental Protection Agency (USEPA)'s chemical mass balance (CMB), are increasingly being used to evaluate sources of pyrogenic polycyclic aromatic hydrocarbons (PAHs) in sediments. This paper describes the assumptions underlying receptor models and discusses challenges in complying with these assumptions in practice. Given the variability within, and the similarity among, pyrogenic PAH source types, model outputs are sensitive to specific inputs, and parsing among some source types may not be possible. Although still useful for identifying potential sources, the technical specialist applying these methods must describe both the results and their inherent uncertainties in a way that is understandable to nontechnical policy makers. The authors present an example case study concerning an investigation of a class of parking-lot sealers as a significant source of PAHs in urban sediment. Principal component analysis is used to evaluate published CMB model inputs and outputs. Targeted analyses of 2 areas where bans have been implemented are included. The results do not support the claim that parking-lot sealers are a significant source of PAHs in urban sediments. © 2013 SETAC.

    Assessing the potential impact of additional mortality from anthropogenic causes on animal populations requires detailed demographic information. However, these data are frequently lacking, making simple algorithms, which require little data, appealing. Because of their simplicity, these algorithms often rely on implicit assumptions, some of which may be quite restrictive. Potential Biological Removal (PBR) is a simple harvest model that estimates the number of additional mortalities that a population can theoretically sustain without causing population extinction. However, PBR relies on a number of implicit assumptions, particularly around density dependence and population trajectory that limit its applicability in many situations. Among several uses, it has been widely employed in Europe in Environmental Impact Assessments (EIA), to examine the acceptability of potential effects of offshore wind farms on marine bird populations. As a case study, we use PBR to estimate the number of additional mortalities that a population with characteristics typical of a seabird population can theoretically sustain. We incorporated this level of additional mortality within Leslie matrix models to test assumptions within the PBR algorithm about density dependence and current population trajectory. Our analyses suggest that the PBR algorithm identifies levels of mortality which cause population declines for most population trajectories and forms of population regulation. Consequently, we recommend that practitioners do not use PBR in an EIA context for offshore wind energy developments. Rather than using simple algorithms that rely on potentially invalid implicit assumptions, we recommend use of Leslie matrix models for assessing the impact of additional mortality on a population, enabling the user to explicitly define assumptions and test their importance.

    Highlights: ► We examined the renewable energy policies of the EU and Turkey in their historical perspectives. ► In the EU there is a progress in renewable energy planning and about support mechanisms. ► In Turkey there is a need for more struggles about increasing the effectiveness of support mechanism. ► The sustainability principle of the EU energy policy has to be a guide for Turkey. - Abstract: Renewable energy as one of the current and substantial issue needs to be investigated in terms of political outlook. So the researches on renewable energy policies under the energy policies of different countries are necessary. The emergence of renewable energy policy was the 20th century but it gained momentum in 21st century. The realization of the polluting nature of the petroleum products, their negative environment effects and the assumptions about the future of non-renewable energy sources were the driving forces behind these politics. The European Union in these conditions tries to play pioneer role. Turkey on the other hand as a candidate country has to harmonize its policies with the Union’s. In this context, objective of this work is to examine the EU and Turkey’s renewable energy policies, make a comparison and as a sustainability of Turkish renewable energy policy construct a future projection in short, medium and long terms.

  18. Super learning to hedge against incorrect inference from arbitrary parametric assumptions in marginal structural modeling.

    Clinical trials are unlikely to ever be launched for many comparative effectiveness research (CER) questions. Inferences from hypothetical randomized trials may however be emulated with marginal structural modeling (MSM) using observational data, but success in adjusting for time-dependent confounding and selection bias typically relies on parametric modeling assumptions. If these assumptions are violated, inferences from MSM may be inaccurate. In this article, we motivate the application of a data-adaptive estimation approach called super learning (SL) to avoid reliance on arbitrary parametric assumptions in CER. Using the electronic health records data from adults with new-onset type 2 diabetes, we implemented MSM with inverse probability weighting (IPW) estimation to evaluate the effect of three oral antidiabetic therapies on the worsening of glomerular filtration rate. Inferences from IPW estimation were noticeably sensitive to the parametric assumptions about the associations between both the exposure and censoring processes and the main suspected source of confounding, that is, time-dependent measurements of hemoglobin A1c. SL was successfully implemented to harness flexible confounding and selection bias adjustment from existing machine learning algorithms. Erroneous IPW inference about clinical effectiveness because of arbitrary and incorrect modeling decisions may be avoided with SL. Copyright © 2013 Elsevier Inc. All rights reserved.

    2018-07-13

    The prevalent view that evaporating black holes should simply be smaller black holes has been challenged by the firewall paradox. In particular, this paradox suggests that something different occurs once a black hole has evaporated to one-half its original surface area. Here, we derive variations of the firewall paradox by tracking the thermodynamic entropy within a black hole across its entire lifetime and extend it even to anti-de Sitter space-times. Our approach sweeps away many unnecessary assumptions, allowing us to demonstrate a paradox exists even after its initial onset (when conventional assumptions render earlier analyses invalid). The most natural resolution may be to accept firewalls as a real phenomenon. Further, the vast entropy accumulated implies a deep firewall that goes 'all the way down' in contrast with earlier work describing only a structure at the horizon.This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'. © 2018 The Author(s).

    Scientific activities take place within the structured sets of ideas and assumptions that define a field and its practices. The conceptual framework of evolutionary biology emerged with the Modern Synthesis in the early twentieth century and has since expanded into a highly successful research program to explore the processes of diversification and adaptation. Nonetheless, the ability of that framework satisfactorily to accommodate the rapid advances in developmental biology, genomics and ecology has been questioned. We review some of these arguments, focusing on literatures (evo-devo, developmental plasticity, inclusive inheritance and niche construction) whose implications for evolution can be interpreted in two ways—one that preserves the internal structure of contemporary evolutionary theory and one that points towards an alternative conceptual framework. The latter, which we label the ‘extended evolutionary synthesis' (EES), retains the fundaments of evolutionary theory, but differs in its emphasis on the role of constructive processes in development and evolution, and reciprocal portrayals of causation. In the EES, developmental processes, operating through developmental bias, inclusive inheritance and niche construction, share responsibility for the direction and rate of evolution, the origin of character variation and organism–environment complementarity. We spell out the structure, core assumptions and novel predictions of the EES, and show how it can be deployed to stimulate and advance research in those fields that study or use evolutionary biology.

    Policy analyses based on traditional or structuralist definitions of the state are important, but they have some limitations for explaining processes related to policymaking, implementation, and results. Bourdieusian sociology links the analysis to objective and subjective dimensions of social practices and can help elucidate these phenomena. This article provides such empirical evidence by analyzing the social genesis of a Brazilian policy that currently serves 18 million workers and was established by the state in 1976 through the Fiscal Incentives Program for Workers' Nutrition (PIFAT/PAT). The study linked the analysis of the trajectory of social agents involved in the policy's formulation to the historical conditions that allowed the policy to exist in the first place. Although the literature treats the policy as a workers' food program (PAT), the current study showed that it actually represented a new model for paying financial subsidies to companies that provided food to their employees, meanwhile upgrading the commercial market for collective meals. The study further showed that the program emerged as an administrative policy, but linked to economic agents. The program became a specific social space in which issues related to workers' nutrition became secondary, but useful for disguising what had been an explicit side of its genesis, namely its essentially fiscal nature.

    The difference in difference (DID) design is a quasi-experimental research design that researchers often use to study causal relationships in public health settings where randomized controlled trials (RCTs) are infeasible or unethical. However, causal inference poses many challenges in DID designs. In this article, we review key features of DID designs with an emphasis on public health policy research. Contemporary researchers should take an active approach to the design of DID studies, seeking to construct comparison groups, sensitivity analyses, and robustness checks that help validate the method's assumptions. We explain the key assumptions of the design and discuss analytic tactics, supplementary analysis, and approaches to statistical inference that are often important in applied research. The DID design is not a perfect substitute for randomized experiments, but it often represents a feasible way to learn about casual relationships. We conclude by noting that combining elements from multiple quasi-experimental techniques may be important in the next wave of innovations to the DID approach.

  4. Geothermal power, policy, and design: Using levelized cost of energy and sensitivity analysis to target improved policy incentives for the U.S. geothermal market

    Science.gov (United States)

    Richard, Christopher L.

    At the core of the geothermal industry is a need to identify how policy incentives can better be applied for optimal return. Literature from Bloomquist (1999), Doris et al. (2009), and McIlveen (2011) suggest that a more tailored approach to crafting geothermal policy is warranted. In this research the guiding theory is based on those suggestions and is structured to represent a policy analysis approach using analytical methods. The methods being used are focus on qualitative and quantitative results. To address the qualitative sections of this research an extensive review of contemporary literature is used to identify the frequency of use for specific barriers, and is followed upon with an industry survey to determine existing gaps. As a result there is support for certain barriers and justification for expanding those barriers found within the literature. This method of inquiry is an initial point for structuring modeling tools to further quantify the research results as part of the theoretical framework. Analytical modeling utilizes the levelized cost of energy as a foundation for comparative assessment of policy incentives. Model parameters use assumptions to draw conclusions from literature and survey results to reflect unique attributes held by geothermal power technologies. Further testing by policy option provides an opportunity to assess the sensitivity of each variable with respect to applied policy. Master limited partnerships, feed in tariffs, RD&D, and categorical exclusions all result as viable options for mitigating specific barriers associated to developing geothermal power. The results show reductions of levelized cost based upon the model's exclusive parameters. These results are also compared to contemporary policy options highlighting the need for tailored policy, as discussed by Bloomquist (1999), Doris et al. (2009), and McIlveen (2011). It is the intent of this research to provide the reader with a descriptive understanding of the role of

    2001-11-19

    An economic evaluation of the impact of policies intended to control emissions of CO{sub 2} and other ''greenhouse gases'' (GHGS) depends on the net costs of these controls and their distribution throughout the production sectors of developed and developing economics. The answers derived from appraisals of these net costs, in turn, stem from what is assumed about the timing of the controls, the pace of technological change, and any short-term secondary benefits from their control. There have only been a few serious attempts to estimate the economic benefits from the policies associated with such long run outcomes. All of the approaches to date have made fairly strong assumptions or relied on contingent valuation estimates of hypothetical situations.

While the status of the three elements is often disputed in specific domestic policy debates......This paper demonstrates how different Greenlandic governments have exploited a narrative of a unique Greenlandic identity to shape and strengthen a foreign policy autonomous from Denmark. Central to this narrative is, on the one hand, the widespread anticipation of more independence in the future......, such as the commissions exploring future Greenlandic constitution and reconciliation with Denmark, on the international policy level there is a remarkable agreement about the narrative.

  10. Energy-environment policy modeling of endogenous technological change with personal vehicles. Combining top-down and bottom-up methods

    International Nuclear Information System (INIS)

    Jaccard, Mark; Murphy, Rose; Rivers, Nic

    2004-01-01

    The transportation sector offers substantial potential for greenhouse gas (GHG) emission abatement, but widely divergent cost estimates complicate policy making; energy-economy policy modelers apply top-down and bottom-up cost definitions and different assumptions about future technologies and the preferences of firms and households. Our hybrid energy-economy policy model is technology-rich, like a bottom-up model, but has empirically estimated behavioral parameters for risk and technology preferences, like a top-down model. Unlike typical top-down models, however, it simulates technological change endogenously with functions that relate the financial costs of technologies to cumulative production and adjust technology preferences as market shares change. We apply it to the choice of personal vehicles to indicate, first, the effect on cost estimates of divergent cost definitions and, second, the possible response to policies that require a minimum market share for low emission vehicles

    Full Text Available Investigation of the external dimension of security policy of Ukraine is stipulated for the need to analyse the current state of relations with organizations such as the Organization for Security and Co-operation in Europe and The Collective Security Treaty Organization, and relations within the Common European Security and Defence Policy. Ukraine’s European Integration means inclusion in the global space security with countries that it shares common values and principles. It does not exclude the collaboration with the countries that belong to other systems of collective security in the scope that is appropriate to basic national interests of Ukraine. It is proved that the activities of the OSCE Special Monitoring Mission is an important contribution to the process of peaceful conflict resolution, and helps to develop democratic principles and foundations of foreign policy. It is determined that the further development of the constructive cooperation between the EU advisory mission under CSDP will provide an opportunity to improve and increase the security of national borders from external threats and challenges, and help to accelerate the process of integration into the European security space. The attention is paid to the fact that, taken into consideration the state of relations with Russia, the further cooperation with the Collective Security Treaty Organization (CSTO may adversely affect the overall security situation in Ukraine and lead to further tension with Russia today.

  12. Maximizing collections from patient services billing.

    2014-01-01

    The field of medical billing and collections continues to evolve along with current developments in U.S. healthcare reform. Although there has been a significant shift of payment responsibility from third-party payers to patients, many practices are not equipped to handle this change. As patients' financial obligations increase, the physician's ability to collect from patients will become increasingly important. Inability to collect bills receivable can adversely affect the revenue cycle of the practice. Solutions include improvement of the point-of-service collection processes, properly trained office staff, written financial policies, and the use of technology to facilitate online payments. Patients should fully understand their financial responsibilities and options available to them for payment of services rendered.

  13. Climate adaptation policy, science and practice - Lessons for communication

    Science.gov (United States)

    Wolf, Johanna

    2017-04-01

    In climate change adaptation research, policy, and practice, institutional culture produces distinct conceptualizations of adaptation, which in turn affect how adaptation work is undertaken. This study examines institutional culture as the four domains of norms, values, knowledge, and beliefs that are held by adaptation scientists, policy- and decision-makers, and practitioners in Western Canada. Based on 31 semi-structured interviews, this article traces the ways in which these four domains interact, intersect, converge, and diverge among scientists, policy- and decision-makers, and practitioners. By exploring the knowledge, backgrounds, goals, approaches, assumptions, and behaviours of people working in adaptation, these interviews map the ways in which institutional culture shapes adaptation work being carried out by local, provincial, and federal governments, nongovernmental organizations, and an international community of scientists (including Canadian scientists). Findings suggest that institutional culture both limits and enables adaptation actions for these actors in important ways, significantly influencing how climate change adaptation is being planned for, and carried out on the ground. As a result, this paper asserts that there is an urgent need to better understand the role that institutional culture plays in order to advance climate change adaptation, both now and in the future. Important lessons for communicating about climate science, climate impacts and adaptation will be presented.

  15. Is the assumption of normality or log-normality for continuous response data critical for benchmark dose estimation?

    Shao, Kan; Gift, Jeffrey S.; Setzer, R. Woodrow

    2013-01-01

    Continuous responses (e.g. body weight) are widely used in risk assessment for determining the benchmark dose (BMD) which is used to derive a U.S. EPA reference dose. One critical question that is not often addressed in dose–response assessments is whether to model the continuous data as normally or log-normally distributed. Additionally, if lognormality is assumed, and only summarized response data (i.e., mean ± standard deviation) are available as is usual in the peer-reviewed literature, the BMD can only be approximated. In this study, using the “hybrid” method and relative deviation approach, we first evaluate six representative continuous dose–response datasets reporting individual animal responses to investigate the impact on BMD/BMDL estimates of (1) the distribution assumption and (2) the use of summarized versus individual animal data when a log-normal distribution is assumed. We also conduct simulation studies evaluating model fits to various known distributions to investigate whether the distribution assumption has influence on BMD/BMDL estimates. Our results indicate that BMDs estimated using the hybrid method are more sensitive to the distribution assumption than counterpart BMDs estimated using the relative deviation approach. The choice of distribution assumption has limited impact on the BMD/BMDL estimates when the within dose-group variance is small, while the lognormality assumption is a better choice for relative deviation method when data are more skewed because of its appropriateness in describing the relationship between mean and standard deviation. Additionally, the results suggest that the use of summarized data versus individual response data to characterize log-normal distributions has minimal impact on BMD estimates. - Highlights: • We investigate to what extent the distribution assumption can affect BMD estimates. • Both real data analysis and simulation study are conducted. • BMDs estimated using hybrid method are more

  17. Halo-independent direct detection analyses without mass assumptions

    International Nuclear Information System (INIS)

    2015-01-01

    Results from direct detection experiments are typically interpreted by employing an assumption about the dark matter velocity distribution, with results presented in the m χ −σ n plane. Recently methods which are independent of the DM halo velocity distribution have been developed which present results in the v min −g-tilde plane, but these in turn require an assumption on the dark matter mass. Here we present an extension of these halo-independent methods for dark matter direct detection which does not require a fiducial choice of the dark matter mass. With a change of variables from v min to nuclear recoil momentum (p R ), the full halo-independent content of an experimental result for any dark matter mass can be condensed into a single plot as a function of a new halo integral variable, which we call h-til-tilde(p R ). The entire family of conventional halo-independent g-tilde(v min ) plots for all DM masses are directly found from the single h-tilde(p R ) plot through a simple rescaling of axes. By considering results in h-tilde(p R ) space, one can determine if two experiments are inconsistent for all masses and all physically possible halos, or for what range of dark matter masses the results are inconsistent for all halos, without the necessity of multiple g-tilde(v min ) plots for different DM masses. We conduct a sample analysis comparing the CDMS II Si events to the null results from LUX, XENON10, and SuperCDMS using our method and discuss how the results can be strengthened by imposing the physically reasonable requirement of a finite halo escape velocity

  18. THE EVOLUTION OR INVOLUTION OF POLICIES TO COMBAT YOUTH UNEMPLOYMENT?

    Directory of Open Access Journals (Sweden)

    Full Text Available A current problem that Romania is facing is high unemployment among young people. Despite the implementation of policies to fight it and improve some of them, this problem is still present on the agenda of the public institutions at the national level and those of the European Union. In Romania, companies that hire inexperienced youngs in force receive from the Romanian state, through European funds between 200-300 euros / month per employee.A boost for companies to increase employability among youth. A first question that arises here is: this policy does not discriminate, directly employability among adults, creating consciously or not, unemployment among them? By the present research I wanted to provide an overview of public policies implemented in this area, showing both the negative aspects which could lead to a deeper issues that are behind it: discrimination of adults in employment and those positive could lead to a clear evolution in this area. The aim is to demonstrate whether the policies implemented in Romania to fight youth unemployment represented an evolution or involution more in this regard? Reported for purpose, targets are those that require to define the concept of young and category directly concerned by these policies, according to Union legislation, to present a concrete statistical data on youth unemployment since 2002 until now,because in 2002 was taken the first private assumption of companies, as simulation of modules for youth employment and analysis of public policies implemented in this field. A final proposed target It is to follow the results of the policies implemented in these years and demonstrate that led to an evolution or involution, including the negative aspects that stood in the way of fulfilling expectations and the proposed actions. To achieve these objectives, the method proposed for research is the analysis of legislation and documents.
