A drug-drug interaction (DDI) is a situation in which a drug affects the activity of another drug synergistically or antagonistically when being administered together. The information of DDIs is crucial for healthcare professionals to prevent adverse drug events. Although some known DDIs can be found in purposely-built databases such as DrugBank, most information is still buried in scientific publications. Therefore, automatically extracting DDIs from biomedical texts is sorely needed. In this paper, we propose a novel position-aware deep multi-task learning approach for extracting DDIs from biomedical texts. In particular, sentences are represented as a sequence of word embeddings and position embeddings. An attention-based bidirectional long short-term memory (BiLSTM) network is used to encode each sentence. The relative position information of words with the target drugs in text is combined with the hidden states of BiLSTM to generate the position-aware attention weights. Moreover, the tasks of predicting whether or not two drugs interact with each other and further distinguishing the types of interactions are learned jointly in multi-task learning framework. The proposed approach has been evaluated on the DDIExtraction challenge 2013 corpus and the results show that with the position-aware attention only, our proposed approach outperforms the state-of-the-art method by 0.99% for binary DDI classification, and with both position-aware attention and multi-task learning, our approach achieves a micro F-score of 72.99% on interaction type identification, outperforming the state-of-the-art approach by 1.51%, which demonstrates the effectiveness of the proposed approach.

A new method is proposed to extract the energy distribution of negative charges, which results from electron trapping by traps in the gate stack of nMOSFET during positive bias temperature instability (PBTI) stress based on the recovery measurement. In our case, the extracted energy distribution of negative charges shows an obvious dependence on energy, and the energy level of the largest energy density of negative charges is 0.01 eV above the conduction band of silicon. The charge energy distribution below that energy level shows strong dependence on the stress voltage. (paper)

Extractive resources are primary source materials used for building infrastructure such as roads, ports, airports, bridges, railways, factories, hospitals, schools and homes. The Policy seeks to protect those essential and finite construction materials for future and existing extraction purposes. Population increases in south-east Queensland the upgrading of rail and port facilities to export coal and other minerals will form a major part in the expansion of extractive industry. Over $4 billion has been committed by the Government and industry to coal infrastructure developments such as upgrades at RG Tanna, Barney Point and the proposed Wiggins Island coal terminals at Gladstone, the Dalryample Bay and Hay Point terminals near Mackay and the Abbot Point coal terminal near Bower. The new Bauhinia regional railway will service the Rolleston coal mines.

This work presents the design and development of a simple ion source, the associated ion extraction optics, and the beam transport of a low-energy and high-current proton accelerator. In its actual version, the ion source can deliver positive proton currents up to 100 mA. This rather high beam current is achieved by adding a small ionization chamber between the discharge chamber containing the filament and the extraction electrode of the ion source. Different parameters of the ion source and the injection beam line are evaluated by means of computer simulations to optimize the beam production and transmission

IGUN is a program for the simulation of positive ion extraction from plasmas. It is based on the well known program EGUN for the calculation of electron and ion trajectories in electron guns and lenses. The mathematical treatment of the plasma sheath is based on a simple analytical model, which provides a numerically stable calculation of the sheath potentials. In contrast to other ion extraction programs, IGUN is able to determine the extracted ion current in succeeding cycles of iteration by itself. However, it is also possible to set values of current, plasma density, or ion current density. Either axisymmetric or rectangular coordinates can be used, including axisymmetric or transverse magnetic fields

In this paper, the authors assess the evolution of African Union policies related to women's and children's health, and analyze how these policies are prioritized and framed. Methods The main method used in this policy analysis was a document review of all African Union policies developed from 1963 to 2010, focusing specifically on policies that explicitly mention health. The findings from this document review were discussed with key actors to identify policy implications. Results With over 220 policies in total, peace and security is the most common AU policy topic. Social affairs and other development issues became more prominent in the 1990s. The number of policies that mentioned health rose steadily over the years (with 1 policy mentioning health in 1963 to 7 in 2010. This change was catalysed by factors such as: a favourable shift in AU priorities and systems towards development issues, spurred by the transition from the Organization of African Unity to the African Union; the mandate of the African Commission on Human and People's Rights; health-related advocacy initiatives, such as the Campaign for the Accelerated Reduction of Maternal Mortality in Africa (CARMMA; action and accountability requirements arising from international human rights treaties, the Millennium Development Goals (MDGs, and new health-funding mechanisms, such as the Global Fund to Fight AIDS, Tuberculosis and Malaria.

Aim. To determine the antimicrobial potential of guava (Psidium guajava) leaf extracts against two gram-negative bacteria (Escherichia coli and Salmonella enteritidis) and two gram-positive bacteria (Staphylococcus aureus and Bacillus cereus) which are some of foodborne and spoilage bacteria. The guava leaves were extracted in four different solvents of increasing polarities (hexane, methanol, ethanol, and water). The efficacy of these extracts was tested against those bacteria through a well-diffusion method employing 50 μL leaf-extract solution per well. According to the findings of the antibacterial assay, the methanol and ethanol extracts of the guava leaves showed inhibitory activity against gram-positive bacteria, whereas the gram-negative bacteria were resistant to all the solvent extracts. The methanol extract had an antibacterial activity with mean zones of inhibition of 8.27 and 12.3 mm, and the ethanol extract had a mean zone of inhibition of 6.11 and 11.0 mm against B. cereus and S. aureus, respectively. On the basis of the present finding, guava leaf-extract might be a good candidate in the search for a natural antimicrobial agent. This study provides scientific understanding to further determine the antimicrobial values and investigate other pharmacological properties. PMID:24223039

The development of shale gas in the United Kingdom (UK) using hydraulic fracturing, more commonly known as ‘fracking’, remains in its infancy. Yet understanding public attitudes for this fledgling industry is important for future policy considerations, decision-making and for industry stakeholders. This study uses data collected from the University of Nottingham, UK nationwide online survey (n=3823) conducted in September 2014, to consider ten hypothesises about the UK public's attitudes towards shale gas. From the survey data we can see that 43.11% of respondents support shale gas extraction in the UK. Furthermore, our results show that women, class DE respondents, non-Conservative party supporters, and respondents who positively associate shale gas with water contamination or earthquakes are less likely to support the extraction of shale gas in the UK. We also discuss potential policy implications for the UK government arising from these findings. - Highlights: • September 2014 survey of British attitudes towards allowing shale gas extraction. • Over 75% or respondents correctly identify shale gas. • 43.11% of respondents support shale gas extraction in the UK.

Leasing policies for the extractive resources

Attanasi, E.D.; Johnson, S.R.

1976-01-01

Much of the available analysis of policies for the disposal of publicly held resources is based on comparatively straightforward extensions of the neoclassical pricing and allocation theory. As such, these analyses have to a large extent not fully incorporated the fact that firms normally acquire rights to these resources in sealed tender markets. In this paper, a simple bidding model is used to show that the choice of disposal policies can influence the firm's bid and also the public revenues obtained from the sale of the resource. It is additionally shown that the implications of such policy choices are conditioned by the firm's attitudes towards risk. Finally, it is argued that a modification of existing prescriptions may be necessary if a more realistic specification of the disposal problem taking account of the sealed tender market in which rights are obtained, is considered. ?? 1976 Annals of Regional Science.

In traditional medicine whole plants or mixtures of plants are used rather than isolated compounds. There is evidence that crude plant extracts often have greater in vitro or/and in vivo antiplasmodial activity than isolated constituents at an equivalent dose. The aim of this paper is to review positive interactions between components of whole plant extracts, which may explain this. Narrative review. There is evidence for several different types of positive interactions between different components of medicinal plants used in the treatment of malaria. Pharmacodynamic synergy has been demonstrated between the Cinchona alkaloids and between various plant extracts traditionally combined. Pharmacokinetic interactions occur, for example between constituents of Artemisia annua tea so that its artemisinin is more rapidly absorbed than the pure drug. Some plant extracts may have an immunomodulatory effect as well as a direct antiplasmodial effect. Several extracts contain multidrug resistance inhibitors, although none of these has been tested clinically in malaria. Some plant constituents are added mainly to attenuate the side-effects of others, for example ginger to prevent nausea. More clinical research is needed on all types of interaction between plant constituents. This could include clinical trials of combinations of pure compounds (such as artemisinin + curcumin + piperine) and of combinations of herbal remedies (such as Artemisia annua leaves + Curcuma longa root + Piper nigum seeds). The former may enhance the activity of existing pharmaceutical preparations, and the latter may improve the effectiveness of existing herbal remedies for use in remote areas where modern drugs are unavailable.

Ethnocentrism is an unacceptable rationale for health care policy: a critique of transplant tourism position statements.

Science.gov (United States)

Evans, R W

2008-06-01

Medical tourism has emerged as a global health care phenomenon, valued at $60 billion worldwide in 2006. Transplant tourism, unlike other more benign forms of medical tourism, has become a flashpoint within the transplant community, underscoring the uneasy relationships among science, religion, politics, ethics and international health care policies concerning the commercialization of transplantation. Numerous professional associations have drafted or issued position statements condemning transplant tourism. Often the criticism is misdirected. The real issue concerns both the source and circumstances surrounding the procurement of donor organs, including commercialization. Unfortunately, many of the position statements circulated to date represent an ethnocentric and decidedly western view of transplantation. As such, the merits of culturally insensitive policy statements issued by otherwise well-intended transplant professionals, and the organizations they represent, must be evaluated within the broader context of foreign relations and diplomacy, as well as cultural and ethical relativity. Having done so, many persons may find themselves reluctant to endorse statements that have produced a misleading social desirability bias, which, to a great extent, has impeded more thoughtful and inclusive deliberations on the issues. Therefore, instead of taking an official position on policy matters concerning the commercial aspects of transplantation, international professional associations should offer culturally respectful guidance.

With its contribution to trade, its coupling with national security, and its symbolism of U.S. technological strength, the U.S. aerospace industry holds a unique position in the Nation's industrial structure. Federal science and technology policy and Federal scientific and technical information (STI) policy loom important as strategic contributions to the U.S. aerospace industry's leading competitive position. However, three fundamental policy problems exist. First, the United States lacks a coherent STI policy and a unified approach to the development of such a policy. Second, policymakers fail to understand the relationship of STI to science and technology policy. Third, STI is treated as a part of general information policy, without any recognition of its uniqueness. This paper provides an overview of the Federal information policy structure as it relates to STI and frames the policy issues that require resolution.

2017-07-01

The American Association on Intellectual and Developmental Disabilities (AAIDD) and The Arc of the United States (The Arc) have a long history of joined efforts to develop, express, and evaluate disability policies. These efforts have resulted in a series of formal statements on critical issues such as education, healthcare, human rights, and criminal justice. Their joint efforts further important policy goals including providing clear strong communication about important policy values and directions, promulgating key principles of high quality supports and services, affirming best professional practices, and emphasizing personal outcomes. In addition, the joint efforts (a) affirm important aspects of organization identity; (b) enhance the organizations' abilities to assure the input of a wide variety of perspectives; (c) engage members' expanded ranges of experiences and talents; (d) multiply staff and leadership resources; (e) increase communication strength and avenues; and (f) establish processes for timely review and revision of policies as critical disability issues arise or change, and new opportunities for policy integration and advancement occur. This article describes the processes used to develop, express, and evaluate the position statements; summarizes the policy content of several joint statements; and discusses the role of these organization position statements.

Consumer opinion on social policy approaches to promoting positive body image: Airbrushed media images and disclaimer labels.

Paraskeva, Nicole; Lewis-Smith, Helena; Diedrichs, Phillippa C

2017-02-01

Disclaimer labels on airbrushed media images have generated political attention and advocacy as a social policy approach to promoting positive body image. Experimental research suggests that labelling is ineffective and consumers' viewpoints have been overlooked. A mixed-method study explored British consumers' ( N = 1555, aged 11-78 years) opinions on body image and social policy approaches. Thematic analysis indicated scepticism about the effectiveness of labelling images. Quantitatively, adults, although not adolescents, reported that labelling was unlikely to improve body image. Appearance diversity in media and reorienting social norms from appearance to function and health were perceived as effective strategies. Social policy and research implications are discussed.

Random Forest Based Coarse Locating and KPCA Feature Extraction for Indoor Positioning System

Directory of Open Access Journals (Sweden)

Yun Mo

2014-01-01

Full Text Available With the fast developing of mobile terminals, positioning techniques based on fingerprinting method draw attention from many researchers even world famous companies. To conquer some shortcomings of the existing fingerprinting systems and further improve the system performance, on the one hand, in the paper, we propose a coarse positioning method based on random forest, which is able to customize several subregions, and classify test point to the region with an outstanding accuracy compared with some typical clustering algorithms. On the other hand, through the mathematical analysis in engineering, the proposed kernel principal component analysis algorithm is applied for radio map processing, which may provide better robustness and adaptability compared with linear feature extraction methods and manifold learning technique. We build both theoretical model and real environment for verifying the feasibility and reliability. The experimental results show that the proposed indoor positioning system could achieve 99% coarse locating accuracy and enhance 15% fine positioning accuracy on average in a strong noisy environment compared with some typical fingerprinting based methods.

2002-01-01

For the extraction of the beam from the Super Proton Synchrotron (SPS) to ring 2 of the Large Hadron Collider (LHC) and the CERN Neutrino to Gran Sasso (CNGS)facility, a new fast-extraction system is being constructed in the long straight section LSS4 of the SPS. Besides extraction bumpers, enlarged aperture quadrupoles and extraction kicker magnets (MKE), six conventional DC septum magnets (MSE) are used. These magnets are mounted on a single rigid support girder, pre-aligned so as to follow the trajectory of the extracted beam and optimise the available aperture. The girder has been motorised in order to optimise the local SPS aperture during setting up, so as to avoid the risk of circulating beam impact on the septum coils. In this note, we briefly present the trajectory and apertures of the beam, we describe the calculations and methods that have been used to determine the magnet position on the girder, and finally we report on the details of the girder movement and alignment.

New Directions for Hardware-assisted Trusted Computing Policies (Position Paper)

Science.gov (United States)

Bratus, Sergey; Locasto, Michael E.; Ramaswamy, Ashwin; Smith, Sean W.

The basic technological building blocks of the TCG architecture seem to be stabilizing. As a result, we believe that the focus of the Trusted Computing (TC) discipline must naturally shift from the design and implementation of the hardware root of trust (and the subsequent trust chain) to the higher-level application policies. Such policies must build on these primitives to express new sets of security goals. We highlight the relationship between enforcing these types of policies and debugging, since both activities establish the link between expected and actual application behavior. We argue that this new class of policies better fits developers' mental models of expected application behaviors, and we suggest a hardware design direction for enabling the efficient interpretation of such policies.

Climate Change. India's Perceptions, Positions, Policies and Possibilities

Energy Technology Data Exchange (ETDEWEB)

Parikh, J.K.; Parikh, K. [Indira Ghandi Institute of Development Research, Mumbai (India)

2002-06-01

In January 2001, the OECD held an expert seminar as part of a pilot project to investigate interactions between the long term agenda for climate change and sustainable development strategies. Experts from both OECD and developing countries attended. Participants identified issues and approaches, based on their regional perspectives, relevant to an evolving, equitable regime for addressing climate change, given various national circumstances, political interests, institutions and capacities to achieve sustainable development objectives. They stressed the importance of both climate mitigation and adaptation policy within a sustainable development framework. Discussions and presentations centred around two broad themes: Synergies and trade-offs between sustainable development objectives and long-term strategies to limit climate change; and How to build analytical and implementation capacity in developing countries to maximise synergies at local, regional and global levels of decision-making. To support seminar discussions, the OECD commissioned several papers (including this one) from non- OECD country experts; authors were asked to comment on key interactions between climate change and sustainable development from their own regional or national perspectives. This paper is being released as an informal working paper in the hope that it will continue to stimulate interest and discussions on these topics in other fora. The paper presents Indian perceptions on the problem of climate change and sustainable development; the kind of negotiating positions that follow from these perceptions; the policies India has undertaken so far and finally India's possibilities for action that can help contain the threat of climate change.

Business Council's position paper on domestic greenhouse policy

International Nuclear Information System (INIS)

1995-01-01

The views of business on government policy issues relating to greenhouse gas abatement are outlined in this paper. While recognizing the need for Australia to make an effective and equitable contribution to global greenhouse gas abatement, it does not believe that acceptance of the targets and timetables implied in the Climate Change Convention will necessarily lead to Australia making an equitable contribution. The feeling is that Australia should adopt a 'no-regrets' approach in line with other OECD countries. This approach includes micro economic reform policies such as emission reduction in energy transport, land management and sink enhancement. Programs fostering relevant research and development in these areas should be adopted. Business is opposed to any form of carbon tax or environmental levy, or any reduction in the diesel fuel rebate. It is believed that the potential of no-regrets measures will be most effectively achieved through a policy package involving mutually supportive government and industry actions. 1 photo

References were screened and independently checked. Studies were quality assessed; characteristics and outcomes were extracted. A narrative synthesis by intervention/policy type. Equity impact was assessed as: positive (reduced inequity), neutral (no difference by SES), negative (increased inequity), mixed (equity impact varied) or unclear.Thirty-eight studies of 40 interventions/policies were included: smokefree (12); price/tax (7); mass media campaigns (1); advertising controls (4); access controls (5); school-based programmes (5); multiple policies (3), individual-level cessation support (2), individual-level support for smokefree homes (1). The distribution of equity effects was: 7 positive, 16 neutral, 12 negative, 4 mixed, 1 unclear. All 7 positive equity studies were US-based: price/tax (4), age-of-sales laws (2) and text-messaging cessation support (1). A British school-based intervention (A Stop Smoking in Schools Trial (ASSIST)) showed mixed equity effects (neutral and positive). Most neutral equity studies benefited all SES groups. Very few studies have assessed the equity impact of tobacco control interventions/policies on young people. Price/tax increases had the most consistent positive equity impact. There is a need to strengthen the evidence base for the equity impact of youth tobacco control interventions. Published by the BMJ Publishing Group Limited.

Deconstructing domestic violence policy

OpenAIRE

Branney, PE

2006-01-01

The primary objectives of this thesis are to, circularly, deconstruct contemporary domestic violence policy while developing and evaluating methods for deconstructing policy. Policy is theorised as a discursive practice, which allows a variety of policies to be compared and critiqued by how they position the people they affect. These are known as subject positions, or subjectivities, and throughout this thesis I attempt to critique policy by examining the (re)construction of subjectivity. In ...

Trace organic compounds in effluents, water streams and aquifers are amply reported. However, the mobile pool of Emerging Organic Contaminants (EOCs) in the deep parts of the vadose zone is hard to estimate, due to difficulties in extraction of sufficient quantity of pore water. Here, we present a new methodology for depth profiling of EOCs in pore water by Positive Displacement Extraction (PDE): Pore water extraction from unsaturated soil samples is carried out by withdrawal of soil cores by direct-push drilling and infiltrating the core by organics free water. We show that EOC concentrations in the water eluted in the plateau region of the inverse breakthrough curve is equal to their pore water concentrations. The method was previously validated for DOC extraction, and here the scope of the methodology is extended to pore water extraction for organic pollutants analysis. Method characteristics and validation were carried out with atrazine, simazine, carbamazepine, venlafaxine, O-desmethylvenlafaxine and caffeine in the concentration range of several ng to several μg/liter. Validation was carried out by laboratory experiments on three different soils (sandy, sandy-clayey and clayey). Field studies in the vadose zone of a SAT system provided 27 m deep EOC profiles with less than 1.5 m spatial resolution. During the percolation treatment, carbamazepine remained persistent, while the other studied EOCs were attenuated to the extent of 50-99%.The highest degradation rate of all studied EOCs was in the aerobic zone. EOC levels based on PDE and extraction by centrifugation were compared, showing a positive bias for centrifugation. Copyright © 2017 Elsevier Ltd. All rights reserved.

Choice vs. voice? PPI policies and the re-positioning of the state in England and Wales.

Hughes, David; Mullen, Caroline; Vincent-Jones, Peter

2009-09-01

CONTEXT AND THESIS: Changing patient and public involvement (PPI) policies in England and Wales are analysed against the background of wider National Health Service (NHS) reforms and regulatory frameworks. We argue that the growing divergence of health policies is accompanied by a re-positioning of the state vis-à-vis PPI, characterized by different mixes of centralized and decentralized regulatory instruments. Analysis of legislation and official documents, and interviews with policy makers. In England, continued hierarchical control is combined with the delegation of responsibilities for the oversight and organization of PPI to external institutions such as the Care Quality Commission and local involvement networks, in support of the government's policy agenda of increasing marketization. In Wales, which has rejected market reforms and economic regulation, decentralization is occurring through the use of mixed regulatory approaches and networks suited to the small-country governance model, and seeks to benefit from the close proximity of central and local actors by creating new forms of engagement while maintaining central steering of service planning. Whereas English PPI policies have emerged in tandem with a pluralistic supply-side market and combine new institutional arrangements for patient 'choice' with other forms of involvement, the Welsh policies focus on 'voice' within a largely publicly-delivered service. While the English reforms draw on theories of economic regulation and the experience of independent regulation in the utilities sector, the Welsh model of local service integration has been more influenced by reforms in local government. Such transfers of governance instruments from other public service sectors to the NHS may be problematic.

How extractive industries affect health: Political economy underpinnings and pathways.

Schrecker, Ted; Birn, Anne-Emanuelle; Aguilera, Mariajosé

2018-06-07

A systematic and theoretically informed analysis of how extractive industries affect health outcomes and health inequities is overdue. Informed by the work of Saskia Sassen on "logics of extraction," we adopt an expansive definition of extractive industries to include (for example) large-scale foreign acquisitions of agricultural land for export production. To ground our analysis in concrete place-based evidence, we begin with a brief review of four case examples of major extractive activities. We then analyze the political economy of extractivism, focusing on the societal structures, processes, and relationships of power that drive and enable extraction. Next, we examine how this global order shapes and interacts with politics, institutions, and policies at the state/national level contextualizing extractive activity. Having provided necessary context, we posit a set of pathways that link the global political economy and national politics and institutional practices surrounding extraction to health outcomes and their distribution. These pathways involve both direct health effects, such as toxic work and environmental exposures and assassination of activists, and indirect effects, including sustained impoverishment, water insecurity, and stress-related ailments. We conclude with some reflections on the need for future research on the health and health equity implications of the global extractive order. Copyright © 2018 The Authors.

Nowadays, olive oil extraction is basically achieved by means of two-phase decanters, which allow a reduction of water consumption and the leaching of phenolic compounds. Despite this, most of the working settings derive from studies carried out on three-phase decanters. Hence, the aim of the present study was to assess the influence of two-phase decanter feed pipe position (FP) on the extraction efficiency and chemical-sensory characteristics of virgin olive oil. Three different positions were considered: at 825 mm (FP1), 610 mm (FP2) and 520 mm (FP3) from the outlet of the oily phase. Position FP3 allowed the highest oil recovery (up to 10%), the lowest percentage of oil in the olive pomace and, in general, a regular trend in terms of oil extraction efficiency. However, the oily must that came out of the decanter was not completely clean in terms of residual content of solid sediment and water. The feeding position partially affected the profile of antioxidant compounds. In two-phase decanters, loading the olive paste close to the outlet of the oily phase is recommended to increase the extraction efficiency without jeopardizing the chemical-sensory characteristics of virgin olive oil. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry.

BDI position on energy policy and energy market deregulation

International Nuclear Information System (INIS)

Kreklau, C.

2003-01-01

Secure energy supplies are indispensable for our modern way of life and our economy. Energy policy is a part of economic policy and must be shaped within the magic triangle of objectives, i.e. security, competitiveness, environmental compatibility. As a result of their outstanding role, electricity and natural gas, with respective shares of 70% in industrial energy use and 85% in energy costs, are in the focus of energy policy interest of the Federation of German Industries (BDI). One important development over the past few years has been the deregulation of the markets for electricity and gas. However, the markedly lower electricity rates to be paid by industry, commercial tariff consumers, and private customers are being offset by new burdens arising from government intervention and taxes. Other dirigistic interventions into the energy market by the red-green federal government since 1998, referred to as 'turning point of energy policy', are invalidating what market opening had been achieved. With a view to a sustainable energy policy for the future, BDI pleads in favor of a broad energy mix. In a mix neutral with respect to competition, this includes the classical energy sources, the renewables, and low-cost, environmentally friendly nuclear power. In principle, it is the forces of the market, coupled with responsible action, which are to steer further developments. On a European level, speedy implementation of the opening of the electricity and gas markets, as decided, should be urged. It is important that the leeway won as a result of deregulation not be constrained again by new regulations. More market, less regulation, and more direct responsibility must provide room for a powerful energy supply system under the premises of the triangle of objectives referred to above. (orig.) [de

Full Text Available In this paper, feature extraction based on data-wave is proposed. The concept of data-wave is introduced to describe the rising and falling trends of the data over the long-term which are detected based on ripple and wave filters. Supported by data-wave, a novel symbol identifier with significant structure features is designed and these features are extracted by constructing pixel chains. On this basis, the corresponding recognition and positioning approach is presented. The effectiveness of the proposed approach is verified by experiments.

Full Text Available Introduction: In the recent years, due to the wide spread of resistant bacteria on one side and several different reports about the side effects of chemical drugs on the other side, vast researches on the medicinal plants have been started. In this study, antimicrobial effect of total extract of Tribulus terrestris L. and its fraction containing Benzoxazine derivative (Terresoxazine was studied for the first time in Iran.Materials and methods: Total aqueous extract of aerial parts of the plant was prepared and in order to separate the components of aqueous extract, liquid/liquid extraction with Petroleum ether was used. Formation of three layers was the result of this extraction. Layers included water fraction, Petroleum ether fraction and a third layer which was formed at the interface of water and petroleum ether. LC/MS system proved the existence of Benzixazine derivative in the water fraction and the thirds fraction. Antimicrobial effects of total extract, water fraction and the third fraction (which were the layers formed after the extraction process were examined against 10 Gram positive and negative and candida spp by cup plate method and Disk diffusion method. Also, the MIC and MBC were determined by micro dilution method.Results: Of 8 evaluated bacteria and 2 Candida spp, the total extract showed antibacterial effect only against E.coli, P.aeruginosa and B.subtilis. Size of the zone of inhibitation increased with increasing the concentration of the extract. Fraction containing Benzoxazine derivative had no effect against tested microbes. MIC and MBC determination showed that B.subtilis had the least sensitivity to the total extract, comparing to other microorganisms. Besides, comparing the zone of inhibitation of Penicillin 200 mg/ml and the zone of inhibitation of the total aqueous extract shows that the solution of total extract in water with 1000 mg/ml concentration and the solution of total extract in DMSO10% with 750 mg/ml density

Extracting Uranium from Seawater: Benefits, Risks and Policy Implication

One of the key issues that need to be addressed regarding the future of nuclear power is the availability of uranium. The most economical way to this day of providing uranium for nuclear energy has been through conventional mining. However, the current projection of the well-known, easily obtainable sources of uranium indicates that global nuclear industry can be supported through the end of the century under the once-through cycle. It, however, could be extended up to 250 years if the speculative uranium sources are taken into account. Uranium is also available in seawater. Extracting uranium from seawater has both pros and cons. The only main obstacles at this point is it not economically competitive compared to the conventional mining. Solving this issue will open up a new era of the way of extracting uranium to meet the future requirement of nuclear energy. As the uranium seawater extraction technology is rapidly being developed and might become feasible in the near future, an appropriate mechanism are required to safeguard the extraction technology.

The aim of this study is to investigate the safety and effectiveness of Excimer laser-assisted lead extraction in Europe. The final European multi-centre study experience is presented. The Excimer is a cool cutting laser (50 degrees C) with a wavelength of 308 nm. The energy is emitted from the tip of a flexible sheath and is absorbed by proteins and lipids, 64% of the energy is absorbed at a tissue depth of 0.06 mm. The sheath is positioned over the lead, and the fibrosis surrounding the lead is vaporized while advancing the sheath without damaging other leads. From August 1996 to March 2001, 383 leads (170 atrial, 213 ventricular) in 292 patients (mean age 61.6 years, range 13-96) were extracted at 14 European centres. Mean implantation time was 74 months (3-358). Most frequent indications were pocket infection (26%), non-functional leads (21%), patient morbidity (21%), septicaemia or endocarditis (14%), erosion (5%), and lead interference (8%). Median extraction time was 15 min (1-300). Complete extraction was achieved in 90.9% of the leads and partial extraction in 3.4%. Extraction failed in 5.7% of the leads. Major complications = perforations caused 10/22 (3.4/5.7%) of the failures. Most partially extracted patients were considered clinically successful, as only minor lead parts without clinical significance were left. Femoral non-laser technique was used to remove 8/12 of the non-complication failures. The total complication rate, including five minor complications (1.7%), was 5.1%. No in-hospital mortality occurred. Pacing and implantable cardioverter-defibrillator leads can safely, effectively, and predictably be extracted. Open-heart extractions can be limited to special cases. The results indicate that the traditional policy of abandoning redundant leads, instead of removing them, may be obsolete in many patients.

Full Text Available Positivism is an empirical approach for understanding of human communication and phenomena, which raised firstly French famous thinker “August Comte”. Human and social Sciences were under domination of positive thought for a long time. In criminal law inter alia Italian famous thinkers sought to analyses the crime problem with a positive approach. However, some of their point of view such as born criminal thesis was not respected by penal scientist, but was affected by their idea was assumed that experiment is the only scientific criterion and basis of criminal law. They thought that value judgments and normative sentences have not scientific character. The positivist approach, developed the abstract thought of classic criminal fundamentalism which was before this, the dominate approach of penal policy towards of objectivism at etiology of crime on the basis of separation of objectivism and subjectivism. But it faced with insufficiency in both methodology and efficiency, so that somebody talked about returning punity approach of classic fundamentalism

Public health professionals have an opportunity to refocus national attention on food and nutrition policy, within a sustainability agenda. A broadly based national Food and Nutrition Policy was developed in 1992. However, its implementation has been selective and primarily based within the health sector. Other major policy areas, for example; industry, agriculture and trade, have dominated Australian nutrition and health policy. A broad, whole-of-government commitment to a comprehensive food and nutrition policy that engages with the community is required to achieve outcomes in terms of public health, a sustainable environment and viable food production for future generations.

The database of recording the snapshots of land parcels history is the foundation for the most of the models on simulating land use/cover change (LUCC) process. But the sequences of temporal snapshots are not sufficient to deduce and describe the mechanism of LUCC process. The temporal relationship between scenarios of LUCC we recorded could not be transfer into causal relationship categorically, which was regarded as a key factor in spatial-temporal reasoning. The proprietor of land parcels adapted themselves to the policies from governments and the change of production market, and then made decisions in this or that way. The occurrence of each change of a land parcel in an urban area was often related with one or more decision texts when it was investigated on the local scale with high resolution of the background scene. These decision texts may come from different sections of a hierarchical government system on different levels, such as villages or communities, towns or counties, cities, provinces or even the paramount. All these texts were balance results between advantages and disadvantages of different interest groups. They are the essential forces of LUCC in human dimension. Up to now, a methodology is still wanted for on how to express these forces in a simulation system using GIS as a language. The presented paper was part of our initial research on this topic. The term "Event" is a very important concept in the frame of "Object-Oriented" theory in computer science. While in the domain of temporal GIS, the concept of event was developed in another category. The definitions of the event and their transformation relationship were discussed in this paper on three modeling levels as real world level, conceptual level and programming level. In this context, with a case study of LUCC in recent 30 years in Xiamen city of Fujian province, P. R. China, the paper focused on how to extract information of events and rules from the policy files collected and integrate

The eight book chapters demonstrate the link between the physical models of the environment and the policy analysis in support of policy making. Each chapter addresses an environmental policy issue using a quantitative modeling approach. The volume addresses three general areas of environmental policy - non-point source pollution in the agricultural sector, pollution generated in the extractive industries, and transboundary pollutants from burning fossil fuels. The book concludes by discussing the modeling efforts and the use of mathematical models in general. Chapters are entitled: modeling environmental policy: an introduction; modeling nonpoint source pollution in an integrated system (agri-ecological); modeling environmental and trade policy linkages: the case of EU and US agriculture; modeling ecosystem constraints in the Clean Water Act: a case study in Clearwater National Forest (subject to discharge from metal mining waste); costs and benefits of coke oven emission controls; modeling equilibria and risk under global environmental constraints (discussing energy and environmental interrelations); relative contribution of the enhanced greenhouse effect on the coastal changes in Louisiana; and the use of mathematical models in policy evaluations: comments. The paper on coke area emission controls has been abstracted separately for the IEA Coal Research CD-ROM

The method for simultaneous extraction and back extraction in liquid three-phase system has been worked out. The equipment designed for that process has been also subject of the patent. The interesting component is extracted first to intermediate phase consists of magnetic solvent keeping two extracting phases separately. The intermediate magnetic liquid has been kept in its position using a stable magnet maintained on the surface of the extraction vessel. Then the component pass from intermediate phase to the third phase as a result of back extraction. Mixing in the extraction and back extraction zones is organized by means of rotating shaft going along the whole apparatus. The extraction and back extraction processes occur simultaneously as a result of continuous flow of solvent in their zones. The single extraction back extraction facilities can be joined in larger batteries. 3 figs

big cities6 and Health Sector Evolution Plan (HSEP. However, the main parts of these programs are related to PHC which needs community based approaches, but there was no any active participation of nursing groups, theoretically and practically. Sometimes the ignorance of nursing position is very precise. For instance, in the conference, it was remarked that FP’s assistant will be trained on January 2016 in SUMS. Whereas Behvarz, as the most familiar discipline with nursing, has had a brilliant role in the last rural primary health care in Iran, the main question is that “Who can be better than educated nursing staff as FP’s assistant?” Although ignorance of nursing position is related to approaches of policy makers, passivity of nursing scholars and nursing managers amplifies the problem. There is a big gap between policy makers and nursing on one hand and nursing scholars and nursing managers on the other hand. In this situation, nursing groups should be more sensitive to new changes such as FP, UCHC and HSEP theoretically and practically for promoting health in the community with preventive and consultative functions of NP. This approach not only helps to establish the real position of nursing but also can decrease the health system costs. This claim surely needs a clear plan. Therefore, teaching nurses according to community-based approaches, interaction between faculty of nursing and community, and conducting surveys seem necessary. Additionally, division of labor in health care system is a focal point for assigning some duties to NPs. Implementation of this idea can practically lead to repetition of the last position of Behvarz for the new generation of nursing in Iran. Today, Iran healthcare system has faced increasing costs due to changes in the patterns of illnesses, prevalence of NCDs and other mentioned problems. Utilization of expert NPs is an approach for declining the effects of such problems. Although policies ignore community- based functions in

Assessing a Template Matching Approach for Tree Height and Position Extraction from Lidar-Derived Canopy Height Models of Pinus Pinaster Stands

Directory of Open Access Journals (Sweden)

Francesco Pirotti

2010-10-01

Full Text Available In this paper, an assessment of a method using a correlation filter over a lidar-derived digital canopy height model (CHM is presented. The objective of the procedure is to obtain stem density, position, and height values, on a stand with the following characteristics: ellipsoidal canopy shape (Pinus pinaster, even-aged and single-layer structure. The process consists of three steps: extracting a correlation map from CHM by applying a template whose size and shape resembles the canopy to be detected, applying a threshold mask to the correlation map to keep a subset of candidate-pixels, and then applying a local maximum filter to the remaining pixel groups. The method performs satisfactorily considering the experimental conditions. The mean tree extraction percentage is 65% with a coefficient of agreement of 0.4. The mean absolute error of height is ~0.5 m for all plots except one. It can be considered a valid approach for extracting tree density and height in regularly spaced stands (i.e., poplar plantations which are fundamental for extracting related forest parameters such as volume and biomass.

Full Text Available In this paper the effects of feed atomizer position and operating conditions on equipment performance (accumulation rate, product recovery, elutriation and thermal efficiency and product properties (moisture content, size distribution, flavonoid degradation and flow properties during spouted bed drying of Bauhinia forficata Link extract are evaluated. The parameters studied were the position of the atomizer system (top spray or bottom spray, the inlet temperature of the spouting gas (80 and 150oC and the feed mass flow rate of concentrated extract relative to the evaporation capacity of the dryer, Ws/Wmax (15 to 100%. Higher accumulation rate values were obtained with the atomizer placed at the bottom of the bed. In this configuration, the accumulation rate increases with the increase in the Ws/Wmax ratio. The best drying performance was obtained for the top spray configuration.

Environmental policy and environment-saving technologies. Economic aspects of policy making under uncertainty

Energy Technology Data Exchange (ETDEWEB)

Ossokina, I.

2003-07-01

It is generally known that natural environment is profoundly influenced by technological change. The direction and the size of this influence are, however, surrounded by uncertainties, which substantially complicate environmental policy making. This dissertation uses game-theoretical models to study policy making under uncertainty about (a) the costs of technological advances in pollution control, (b) the preferences of the policy maker and the voters, and (c) the consequences of policy measures. From a positive point of view the analysis provides explanations for environmental policies in modern democracies. From a normative point of view it gives a number of recommendations to improve environmental policies.

Energy policy in transport and transport policy

Van Dender, Kurt

2009-01-01

Explanations for, and indirect evidence of, imperfections in the market for private passenger vehicle fuel economy suggest there is a reasonable case for combining fuel economy standards and fuel or carbon taxes to contribute to an energy policy that aims to reduce greenhouse gas emissions and improve energy security. Estimates of key elasticities, including the rebound effect, indicate that the positive and negative side-effects of fuel economy measures on transport activities and external costs are limited. However, an energy policy for transport does not replace a transport policy that aims to manage the main transport externalities including congestion and local pollution. Conventional marginal cost estimates and standard cost-benefit reasoning suggest that policies that address congestion and local pollution likely bring benefits at least as large as those from fuel economy measures. But the large uncertainty on the possible effects of greenhouse gas emissions constitutes a strong challenge for standard cost-benefit reasoning. Emerging results from methods to cope with this uncertainty suggest that policies to stimulate the widespread adoption of low-carbon technologies in transport are justified.

The possibility to obtain DNA from smears is a valuable alternative to remedy the lack of samples when they are totally used for bacilloscopy; this technique solves the biosafety problem related to a possible accident with the transportation of flasks containing potentially transmissible clinical samples. Hence, the purpose of this study was to utilize the insertion sequence IS6110 for amplification of DNA from a smear-positive sample for tuberculosis (TB) diagnosis. Among the 52 positive bacilloscopies, sensitivity, specificity, positive predictive value and negative predictive value were 52.3%, 100%, 100% and 89.7%, respectively whereas accuracy was 90.7%. The IS6110-based PCR for TB diagnosis developed in DNA extracted from a positive smear is a fast, simple, specific, and safe method. Copyright © 2014 Asociación Argentina de Microbiología.

Formulating Public Policy in Croatia and the Problem of Policy Coordination

Directory of Open Access Journals (Sweden)

Zdravko Petak

2008-01-01

Full Text Available The paper explores the role of politicians and civil servants in the process of horizontal and vertical policy coordination, with a special emphasis on the specific context of Croatia. Starting from Guy Peters’ typology, which distinguishes four distinct types of coordination, ranging from more simple to more complex ones – negative coordination, positive coordination, policy integration and development of strategies for government, the author stresses that the Croatian case is connected with failure in achieving all types of coordination. One of the reasons for such a situation lies in a low level of applying classical policy analysis in the Croatian public administration system. A direct consequence of this is the existence of the system of coordination based on ad hoc assessment of proposed policies, and not on standard policy analysis tools. Therefore, in the lack of central government policy unit the prominent role in such a system belongs to the finance Minister, who serves as some kind of “policy switchman”.

Administrator turnover and its impact on the quality of patient care are important concerns in the nursing home industry. This study evaluates a model to determine which factors, attitudes, and personal characteristics can predict tenure. Responses to a survey from 290 nursing home administrators (NHAs) who furnished data on their previous positions were analyzed using logistic regression methods. The extracted model correlates tenure with the administrator's past patterns of stability, community attachment, organizational commitment, and facility performance. The model is particularly effective (85% accuracy) in flagging NHAs who are likely to depart within their first 3 years of employment. Implications of these findings for recruitment, retention, and licensure policy are discussed.

Schleich, Joachim; Faure, Corinne

2017-01-01

This paper empirically analyses the antecedents of citizens’ perceptions of the relevance of international climate policy. Its use of representative surveys in the USA, China and Germany controls for different environmental attitudes and socio-economic factors between countries. The findings of the micro-econometric analysis suggest that the perceived relevance of international climate policy is positively affected by its perceived effectiveness, approval of the key topics discussed at international climate conferences, and environmental attitudes, but is not affected by perceived procedural justice. A higher level of perceived trust in international climate policy was positively related to perceived relevance in the USA and in China, but not in Germany. Citizens who felt that they were well informed and that their position was represented at climate summits were more likely to perceive international climate policy as relevant in China in particular. Generally, the results show only weak evidence of socio-demographic effects. - Highlights: • Perceptions of climate-policy relevance increase with perceptions of effectiveness. • In China and the USA, trust increases perceptions of climate-policy relevance. • Environmental attitudes are related to perceptions of climate-policy relevance. • In China, well-informed citizens perceive climate policy as more relevant. • Socio-demographics only weakly affect perceptions of climate-policy relevance.

Secondhand smoke (SHS) exposure poses serious health risks for all nonsmokers, especially children and pregnant women. SHS is estimated to contribute to heart attacks in nonsmokers and nearly 53,800 deaths in the U.S. annually. A literature review of English-language articles was performed using PubMed, organizational websites, and pertinent review articles. Over the past 25 years, smokefree policies have protected nearly half the U.S. population from the adverse health effects of SHS. Smokefree policies have been shown to improve health outcomes with no consequences to local businesses. As of April 2013, a total of 24 states and 561 municipalities and territories, including the District of Columbia, New York City, Puerto Rico, and the U.S. Virgin Islands, have established laws that require nonhospitality workplaces, restaurants, and bars to be 100% smokefree. Four other states-Florida, Indiana, Louisiana, and Nevada-have smokefree laws that cover restaurants but provide an exemption for stand-alone bars. At least 14 states have no smokefree laws. This paper describes the benefits of policies that reduce SHS and concludes with recommendations for future directions. The American College of Preventive Medicine (ACPM) recommends expanded clean indoor air policies for workplaces, stand-alone bars, restaurants, and multi-use family housing such as apartment buildings. ACPM recommends clean air policies for all university campuses, secondary school campuses, primary schools, child care centers, and city landmarks to further shift social norms and protect the health of children, adolescents, and adults. ACPM recommends closing existing gaps in clean indoor air policies. Copyright © 2013 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

The Structural Underpinnings of Policy Learning: A Classroom Policy Simulation

Science.gov (United States)

Bird, Stephen

This paper investigates the relationship between the centrality of individual actors in a social network structure and their policy learning performance. In a dynamic comparable to real-world policy networks, results from a classroom simulation demonstrate a strong relationship between centrality in social learning networks and grade performance. Previous research indicates that social network centrality should have a positive effect on learning in other contexts and this link is tested in a policy learning context. Second, the distinction between collaborative learning versus information diffusion processes in policy learning is examined. Third, frequency of interaction is analyzed to determine whether consistent, frequent tics have a greater impact on the learning process. Finally, the data arc analyzed to determine if the benefits of centrality have limitations or thresholds when benefits no longer accrue. These results demonstrate the importance of network structure, and support a collaborative conceptualization of the policy learning process.

Full Text Available Abstract Background and Objectives: Development of bacterial resistance to antibiotics has led to an increased tendency to development of new more effective and non-toxic antimicrobial compounds. In this study, the inhibitory and lethal effects of aqueous, ethanolic, and hydroalcoholic extracts of aerial parts of Salvia chorassanica were evaluated against Listeria monocytogenes, Bacillus cereus, Salmonella typhi, and Escherichia coli O:157. Methods: In this study, Kirby–Bauer disk diffusion method was used to evaluate antimicrobial activity. In this method, bacteria were cultivated as grass culture in Mueller Hinton Agar (MHA media. To determine the minimum inhibitory concentration and minimum bactericidal concentration, micro-dilution method with ELISA and addition of phenyl tetrazolium chloride reagent, were used. Data were analyzed using one-way ANOVA and Duncan’s test at the significance level of p<0.05. Results: The highest diameter of inhibition in agar diffusion method was related to hydroalcoholic extract of aerial parts of Salvia chorassanica against Gram-positive bacteria Bacillus cereus. The amount of calculated MIC of hydro-alcoholic extract for Gram-positive bacteria was 30mg/ml. This amount was the lowest among other measured MIC. Conclusion: Based on the results of this study, Gram-negative bacteria showed more resistance to different extracts of aerial parts of Salvia chorassanica as compared to Gram-positive bacteria, so that Salmonella typhi was found to be the most resistant bacterium among the tested bacteria.

Full Text Available Anthocyanins red pigments that give color a wide range of fruits, berries and flowers. In the food industry it is widely known as a dye a food additive E163. To extract from natural vegetable raw materials traditionally used ethanol or acidified water, but in same technologies it’s unacceptable. In order to expand the use of anthocyanins as colorants and antioxidants were explored extracting pigments alcohols with different structures of the carbon skeleton, and the position and number of hydroxyl groups. For the isolation anthocyanins raw materials were extracted sequentially twice with t = 60 C for 1.5 hours. The evaluation was performed using extracts of classical spectrophotometric methods and modern express chromaticity. Color black currant extracts depends on the length of the carbon skeleton and position of the hydroxyl group, with the alcohols of normal structure have higher alcohols compared to the isomeric structure of the optical density and index of the red color component. This is due to the different ability to form hydrogen bonds when allocating anthocyanins and other intermolecular interactions. During storage blackcurrant extracts are significant structural changes recoverable pigments, which leads to a significant change in color. In this variation, the stronger the higher the length of the carbon skeleton and branched molecules extractant. Extraction polyols (ethyleneglycol, glycerol are less effective than the corresponding monohydric alcohols. However these extracts saved significantly higher because of their reducing ability at interacting with polyphenolic compounds.

Urtica dioica or stinging nettle is traditionally used as an herbal medicine in Western Asia. The current study represents the investigation of antimicrobial activity of U. dioica from nine crude extracts that were prepared using different organic solvents, obtained from two extraction methods: the Soxhlet extractor (Method I), which included the use of four solvents with ethyl acetate and hexane, or the sequential partitions (Method II) with a five solvent system (butanol). The antibacterial and antifungal activities of crude extracts were tested against 28 bacteria, three yeast strains and seven fungal isolates by the disc diffusion and broth dilution methods. Amoxicillin was used as positive control for bacteria strains, vancomycin for Streptococcus sp., miconazole nitrate (30 microg/mL) as positive control for fungi and yeast, and pure methanol (v/v) as negative control. The disc diffusion assay was used to determine the sensitivity of the samples, whilst the broth dilution method was used for the determination of the minimal inhibition concentration (MIC). The ethyl acetate and hexane extract from extraction method I (EA I and HE I) exhibited highest inhibition against some pathogenic bacteria such as Bacillus cereus, MRSA and Vibrio parahaemolyticus. A selection of extracts that showed some activity was further tested for the MIC and minimal bactericidal concentrations (MBC). MIC values of Bacillus subtilis and Methicillin-resistant Staphylococcus aureus (MRSA) using butanol extract of extraction method II (BE II) were 8.33 and 16.33mg/mL, respectively; while the MIC value using ethyl acetate extract of extraction method II (EAE II) for Vibrio parahaemolyticus was 0.13mg/mL. Our study showed that 47.06% of extracts inhibited Gram-negative (8 out of 17), and 63.63% of extracts also inhibited Gram-positive bacteria (7 out of 11); besides, statistically the frequency of antimicrobial activity was 13.45% (35 out of 342) which in this among 21.71% belongs to

This systematic review examined the impact of universal policies on socioeconomic inequities in obesity, dietary and physical activity behaviours among adults and children. PRISMA-Equity guidelines were followed. Database searches spanned from 2004 to August 2015. Eligible studies assessed the impact of universal policies on anthropometric, dietary or physical activity-related outcomes in adults or children according to socioeconomic position. Thirty-six studies were included. Policies were classified as agentic, agento-structural or structural, and their impact on inequities was rated as positive, neutral, negative or mixed according to the dominant associations observed. Most policies had neutral impacts on obesity-related inequities regardless of whether they were agentic (60% neutral), agento-structural (68% neutral) or structural (67% neutral). The proportion of positive impacts was similar across policy types (10% agentic, 18% agento-structural and 11% structural), with some differences for negative impacts (30% agentic, 14% agento-structural and 22% structural). The majority of associations remained neutral when stratified by participant population, implementation level and socioeconomic position measures and by anthropometric and behavioural outcomes. Fiscal measures had consistently neutral or positive impacts on inequities. Findings suggest an important role for policy in addressing obesity in an equitable manner and strengthen the case for implementing a broad complement of policies spanning the agency-structure continuum. © 2016 World Obesity Federation.

2010-06-01

The paper under the above mentioned title tries to develop an understanding of the question why energy relations and cooperation between the European Union and Russia in energy matters haven't been very successful over the last decade and why relations are affected by crises frequently. In order to answer these questions meaningfully, several steps need to be made: First, the paper offers a summary of recent policy debate on energy questions on the EU side. It identifies relevant participants in the ''political arena'' and describes their positioning and interaction, based on a multi-level-governance approach. Following a look at history of European energy policy developments, the paper concludes that a complex European policy field has developed recently, although there is no direct responsibility for energy matters with European institutions so far, but that the justification for any law-making in the said areas is deducted from secondary EU level responsibilities such as common market, competition law or environmental matters. However, there is a huge bandwidth of positions between political actors, civil service, parliaments, industry associations, consumers - organizations etc as well as between community and national level organizations. Not only a battle for power and competence between these levels hinders a straight and consistent energy policy across the EU, there is also significantly different focus with different players on where to put effort between conflicting objectives of the ''European Energy Triangle'', demanding (1) secure and reliable, (2) cheap and competitive as well as (3) environmentally friendly energy supplies. Despite all these differences, within the EU, a strong and well-regarded new area of policy debate has developed in the energy sector and a lot has been achieved. Observers frequently demand the EU to ''speak with one voice'' towards third parties, eg gas producing

Influencing public policies: Two (very good) reasons to look toward scientific knowledge in public policy.

Science.gov (United States)

Gagnon, François; Bellefleur, Olivier

2014-07-11

The healthy public policy movement rests on the belief that a range of public policies should be at least partly informed by evidence demonstrating the positive effects of these policies on population health, health inequalities and their determinants. In order to address certain difficulties that the movement faces, knowledge produced in various scientific disciplines regarding public policies may provide some valuable guidance. In this short commentary, we examine how knowledge from the scientific disciplines investigating public policies makes it possible to address two difficulties in the development of healthy public policies: 1) adequately anticipating the effects of public policies, and 2) assessing the political viability of the policies being promoted. Since urban traffic policies are of interest to most of the other contributors to this supplement, we use examples from this field to illustrate some of our points.

The color of mulberry wine is extremely unstable in processing and aging. This paper investigates the effects of tannin extract and yeast extract on the color and color-preserving characteristics of mulberry wine made from the Dashi cultivar. The results showed that the maximum absorption wavelength in both tannin extract and yeast extract groups changed generating the red shift effect. The color of the tannin extract maintained a good gloss in the first 4 months, while the yeast extract group showed remarkable color preservation for the first 3 months. The total anthocyanin and cyanidin-3-rutinoside contents in both experiment groups were significantly higher than that of the control group, thus proving that tannin extract and yeast extract both exert a remarkably positive effect on preserving the color of mulberry wine during its aging. Moreover, sensory analysis indicated that the quality of mulberry wine treated with tannin extract was significantly higher than that of the control. The distinct color of mulberry wine is one of the foremost qualities that imprints on consumers' senses, but it is extremely unstable in processing and aging. However, the color protection of mulberry wine was not studied previously. In this study, we found that tannin extract and yeast extract both exert a remarkably positive effect on preserving the color of mulberry wine during aging. The study is of great significance as a guide to improving the color stability of mulberry wine, thereby also improving and promoting the development of the mulberry deep processing industry. © 2018 Institute of Food Technologists®.

Towards understanding the drivers of policy change: a case study of infection control policies for multi-drug resistant tuberculosis in South Africa.

Explaining policy change is one of the central tasks of contemporary policy analysis. In this article, we examine the changes in infection control policies for multi-drug resistant tuberculosis (MDR-TB) in South Africa from the time the country made the transition to democracy in 1994, until 2015. We focus on MDR-TB infection control and refer to decentralised management as a form of infection control. Using Kingdon's theoretical framework of policy streams, we explore the temporal ordering of policy framework changes. We also consider the role of research in motivating policy changes. Policy documents addressing MDR-TB in South Africa over the period 1994 to 2014 were extracted. Literature on MDR-TB infection control in South Africa was extracted from PubMed using key search terms. The documents were analysed to identify the changes that occurred and the factors driving them. During the period under study, five different policy frameworks were implemented. The policies were meant to address the overwhelming challenge of MDR-TB in South Africa, contextualised by high prevalence of HIV infection, that threatened to undermine public health programmes and the success of antiretroviral therapy rollouts. Policy changes in MDR-TB infection control were supported by research evidence and driven by the high incidence and complexity of the disease, increasing levels of dissatisfaction among patients, challenges of physical, human and financial resources in public hospitals, and the ideologies of the political leadership. Activists and people living with HIV played an important role in highlighting the importance of MDR-TB as well as exerting pressure on policymakers, while the mass media drew public attention to infection control as both a cause of and a solution to MDR-TB. The critical factors for policy change for infection control of MDR-TB in South Africa were rooted in the socioeconomic and political environment, were supported by extensive research, and can be framed

Determination of intensity and position of the extracted electron beam at ELSA by means of high-frequency resonators; Bestimmung von Intensitaet und Position des extrahierten Elektronenstrahls an ELSA mittels Hochfrequenzresonatoren

Energy Technology Data Exchange (ETDEWEB)

Pusch, Thorsten

The electron stretcher facility ELSA provides an electron beam of a few hundred pA used for the generation of bremsstrahlung photons probing the nucleon structure in a detector setup. For the correct interpretation of the events registered, the persistence of the beam position over time is crucial. Its continuous monitoring has been enabled by setting up a measurement system based on resonant cavities. Position signals at a frequency of 1.5 GHz and below one aW of power can be abstracted from the beam without degrading its quality. After frequency down-conversion to a few kHz, a narrow bandwidth detection performed by lock-in amplifiers separates them from noise. A maximum sample rate of 9 Hz and a resolution of one tenth of a millimeter could be achieved. The position signals have to be normalized to the beam current which is monitored by another dedicated resonator. The measurement precision down to a few pA allows for the accelerator extraction mechanism to be controlled by a feedback loop in order to obtain the respective requested current. (orig.)

Governing the Extractive Sector: The Politics of Globalisation and Copper Policy in Chile

Directory of Open Access Journals (Sweden)

Jewellord T. Nem Singh

2010-09-01

Full Text Available Chile exhibits an immense continuity in its copper policy and the sector’s reliable output contributes enormously to the tax revenues of the state. Copper in Chile is thus an interesting case because it challenges the presumed failure of neoliberal reforms in Latin America. It does this in a number of different ways. First, the sector is a clear success in terms of its output and contribution to GDP. Second, private capital and foreign direct investment in particular plays a critical role in developing the mining sector. Third, state- owned CODELCO has stood firmly against multinational companies. And fourth, Chile simultaneously exhibits a stability of rules inherited from Pinochet’s neoliberalism; labour relations characterised by conflict and co-optation; and a depoliticised mode of governance marked by copper policy technopols and an indirect link between copper and social policy. This paper argues that the Chilean state under La Concertación government has played an important ‘steering’ role by defusing the various political conflicts, contradictions and tensions in copper policy.

Government, politics and health policy: A quantitative analysis of 30 European countries.

Mackenbach, Johan P; McKee, Martin

Public health policies are often dependent on political decision-making, but little is known of the impact of different forms of government on countries' health policies. In this exploratory study we studied the association between a wide range of process and outcome indicators of health policy and four groups of political factors (levels of democracy, e.g. voice and accountability; political representation, e.g. voter turnout; distribution of power, e.g. constraints on the executive; and quality of government, e.g. absence of corruption) in contemporary Europe. Data on 15 aspects of government and 18 indicators of health policy as well as on potential confounders were extracted from harmonized international data sources, covering 30 European countries and the years 1990-2010. In a first step, multivariate regression analysis was used to relate cumulative measures of government to indicators of health policy, and in a second step panel regression with country fixed effects was used to relate changes in selected measures of government to changes in indicators of health policy. In multivariate regression analyses, measures of quality of democracy and quality of government had many positive associations with process and outcome indicators of health policy, while measures of distribution of power and political representation had few and inconsistent associations. Associations for quality of democracy were robust against more extensive control for confounding variables, including tests in panel regressions with country fixed effects, but associations for quality of government were not. In this period in Europe, the predominant political influence on health policy has been the rise of levels of democracy in countries in the Central & Eastern part of the region. In contrast to other areas of public policy, health policy does not appear to be strongly influenced by institutional features of democracy determining the distribution of power, nor by aspects of political

Impact of entrepreneurship policies on opportunity to startup

Directory of Open Access Journals (Sweden)

Ali Davari

2017-09-01

Full Text Available During the previous decades, policy makers have formulated policies for developing entrepreneurship in different countries in order to decrease unemployment and poverty toward sustainable development. Some of these policies include encouraging people to be an entrepreneur, opportunity creation, educating new skills to entrepreneurs and so on. In recent years an appropriate context has been formed for entrepreneurship development in Iran and some programs have been executed. Therefore, formulating appropriate frameworks to guide Iranian government in this way is a necessity. This paper evaluates the impact of entrepreneurship policies on opportunity to startup in Iran. The results of path analysis indicate that supportive financial and non-financial actions influence positively on opportunity to startup. In addition, education and culture also influence positively on opportunity to startup. Finally, legislation also positively influences on opportunity to startup.

2015-01-01

An investigation on the extraction of citronella oil from Cymbopogon nardus (C. nardus) using a custom made medium scale steam distillation apparatus has been conducted. The Clevenger apparatus was used to generate a continuous flow of the hydrosol, creating an efficient distillation system. In the case for C. nardus leave samples orientation; the sleeping/ standing and close/ loose packing in steam distillator was found to have significant effects on the yield of extraction. The 3.5 hours distillation process produced an extraction yield of 0.64 % in sleeping position of the leaves as compared to the standing position (0.43 %), while the loose packing (0.70 %) has almost two fold of yield percentage as compared to the close-packing (0.40 %) of the leaves. Therefore, the steam distillation of C. nardus leaves using a custom made medium scale steam distillation apparatus was found to be most effective in the combination of sleeping position with a loose packing. Furthermore, the age of C. nardus leaves also affect the physical and chemical quality of the citronella oil extracted. The younger leaves produced citronella oil that consists mainly of citronellal, citronellol and geraniol while the older leaves contained a high composition of citral. (author)

It is important to gain a thorough understanding of positive coping methods adopted by medical emergency personnel to manage stressful situations associated with accidents and emergencies. Thus, the purpose of this study was to gain a better understanding of positive coping strategies used by emergency medical service providers. This study was conducted using a qualitative content analysis method. The study participants included 28 pre-hospital emergency personnel selected from emergency medical service providers in bases located in different regions of the city of Mashhad, Iran, from April to November 2016. The purposive sampling method also was used in this study, which was continued until data saturation was reached. To collect the data, semistructured open interviews, observations, and field notes were used. Four categories and 10 subcategories were extracted from the data on the experiences of pre-hospital emergency personnel related to positive coping strategies. The four categories included work engagement, smart capability, positive feedback, and crisis pioneering. All the obtained categories had their own subcategories, which were determined based on their distinctly integrated properties. The results of this study show that positive coping consists of several concepts used by medical emergency personnel, management of stressful situations, and ultimately quality of pre-hospital clinical services. Given the fact that efficient methods such as positive coping can prevent debilitating stress in an individual, pre-hospital emergency authorities should seek to build and strengthen "positive coping" characteristics in pre-hospital medical emergency personnel to deal with accidents, emergencies, and injuries through adopting regular and dynamic policies.

This paper is aimed at critically assessing the extent to which Non-Communicable Disease NCD-related policies introduced in Bangladesh align with the World Health Organization's (WHO) 2013-2020 Action Plan for the Global Strategy for the Prevention and Control of NCDs. The authors reviewed all relevant policy documents introduced by the Government of Bangladesh since its independence in 1971. The literature review targeted scientific and grey literature documents involving internet-based search, and expert consultation and snowballing to identify relevant policy documents. Information was extracted from the documents using a specific matrix, mapping each document against the six objectives of the WHO 2013-2020 Action Plan for the Global Strategy for the Prevention and Control of NCDs. A total of 51 documents were identified. Seven (14%) were research and/or surveys, nine were on established policies (17%), while seventeen (33%) were on action programmes. Five (10%) were related to guidelines and thirteen (25%) were strategic planning documents from government and non-government agencies/institutes. The study covered documents produced by the Government of Bangladesh as well as those by quasi-government and non-government organizations irrespective of the extent to which the intended policies were implemented. The policy analysis findings suggest that although the government has initiated many NCD-related policies or programs, they lacked proper planning, implementation and monitoring. Consequently, Bangladesh over the years had little success in effectively addressing the growing burden of non-communicable diseases. It is imperative that future research critically assess the effectiveness of national NCD policies by monitoring their implementation and level of population coverage.

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

International Nuclear Information System (INIS)

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

“What Cultural Policies?” Explicit and Implicit Cultural Policies in Lebanon

Directory of Open Access Journals (Sweden)

Nadia von Maltzahn

2017-01-01

Full Text Available Cultural policies define a vision for culture, and provide frameworks for institutional practice to translate this vision on the ground. A 1981 study on Lebanese cultural policy reached the conclusion that one cannot speak of cultural policies in Lebanon if one refers to state laws, regulations and plans. However, if cultural policy was understood as the method of a state to give its citizens the space to develop themselves in a way that they could create culture, one could certainly speak of cultural policies in Lebanon (Abou Rizk. In cultural policy research, there is a distinction between explicit and implicit cultural policy (Ahearne. In this article, the concept of explicit and implicit cultural policy is applied to the case of Lebanon. The two terms are extended so that the former does not only include cultural policies designatedas such by the state, but also those created by civil society actors, and that the latter does not only include political strategies, but also practices that in the end determine cultural policies. Drawing on empirical research conducted in the context of a larger study on the role of cultural institutions in the public sphere, the power struggles between different actors involved in cultural policy making cultural policy defined in the Lebanese context, which in turn will be positioned within the regional context.

2018-04-01

Avicennia rumphiana is one of abundant mangrove found in Indonesia. Multilevel extraction methods were simultaneously conducted to screen the antioxidant activity from mangrove. The leaves, fruits and barks were consequently extracted using n-hexane, ethyl acetate and ethanol. The presence of phenolic, flavonoids and tannins compounds were characterized by quantitative and qualitative phytochemical assay as well as the antioxidant activity was examined using DPPH-free radical scavenging assay. The phytochemical test revealed that all of the extracts showed positive result. The fruits extract exhibited the highest phenolic, flavonoid and tannin (23.86 mg/g, 13.77 mg/g and 74.63 mg/g), respectively. The extracts were further confirmed for antioxidant using IC50 value and revealed that ethyl acetate extract has antioxidant activity better than n-hexane and ethyl acetate extract. Furthermore, this study indicated that mangrove Avicennia rumphiana could be subsequently explored for other biological activities due to their potential secondary metabolites.

Full Text Available Piper betle L. has traditionally been used in alternative medicine in different countries for various therapeutic purposes, including as an anti-infective agent. However, studies reported in the literature are mainly on its activities on drug susceptible bacterial strains. This study determined the antimicrobial activities of its ethanol, methanol, and supercritical CO2 extracts on clinical isolates of multiple drug resistant bacteria which have been identified by the Infectious Disease Society of America as among the currently more challenging strains in clinical management. Assay methods included the standard disc diffusion method and the broth microdilution method for the determination of the minimum inhibitory concentration (MIC and the minimum bactericidal concentrations (MBC of the extracts for the test microorganisms. This study revealed the bactericidal activities of all the P. betle leaf crude extracts on methicillin-resistant Staphylococcus aureus (MRSA, vancomycin-resistant Enterococcus (VRE, extended spectrum β-lactamase-producing Enterobacteriaceae, carbapenem-resistant Enterobacteriaceae, and metallo-β-lactamase-producing Pseudomonas aeruginosa and Acinetobacter baumannii, with minimum bactericidal concentrations that ranged from 19μg/ml to 1250 μg/ml. The extracts proved to be more potent against the Gram positive MRSA and VRE than for the Gram negative test bacteria. VRE isolates were more susceptible to all the extracts than the MRSA isolates. Generally, the ethanol extracts proved to be more potent than the methanol extracts and supercritical CO2 extracts as shown by their lower MICs for both the Gram positive and Gram negative MDRs. MTT cytotoxicity assay showed that the highest concentration (100 μg/ml of P. betle ethanol extract tested was not toxic to normal human dermal fibroblasts (HDFn.

We consider the world oil price as a foreign variable that will influence domestic economy as in regular small open economy model. In this paper, we employ the Monte Carlo algorithm to Near-SVAR models (If some of the VAR equations have regressors not included in the others. We find that there is a positive stock price response to monetary policy shock both aggregated and sectoral stock price. In term of interaction between fiscal policy shock and stock market, we find that all sectors respond negative relationship. From this empirical finding, fiscal policy crowd out private sector activity in market, thus, its effect will be impotent in economy. We also provide the evidence that not only both policies are able to influence the stock price individually, but also the interaction between monetary and fiscal policy is important in explaining stock market performance.

2013-10-16

Background:In a number of diseases, certain genes are reported to be strongly methylated and thus can serve as diagnostic markers in many cases. Scientific literature in digital form is an important source of information about methylated genes implicated in particular diseases. The large volume of the electronic text makes it difficult and impractical to search for this information manually.Methodology:We developed a novel text mining methodology based on a new concept of position weight matrices (PWMs) for text representation and feature generation. We applied PWMs in conjunction with the document-term matrix to extract with high accuracy associations between methylated genes and diseases from free text. The performance results are based on large manually-classified data. Additionally, we developed a web-tool, DEMGD, which automates extraction of these associations from free text. DEMGD presents the extracted associations in summary tables and full reports in addition to evidence tagging of text with respect to genes, diseases and methylation words. The methodology we developed in this study can be applied to similar association extraction problems from free text.Conclusion:The new methodology developed in this study allows for efficient identification of associations between concepts. Our method applied to methylated genes in different diseases is implemented as a Web-tool, DEMGD, which is freely available at http://www.cbrc.kaust.edu.sa/demgd/.

Many scientists conduct research with direct policy relevance, whether it be producing sea-level projections that are taken-up by local decision-makers, or developing new agricultural technologies. All scientists are affected by policies made by their respective local, regional, and federal governments. For example, budgets affect the grant resources available to conduct research and policies on visas influence the accessibility of new positions for foreign scientists. As a result, many scientists would like to engage with the policy domain, and either bring their science to bear on new policies that are in the works (science-for-policy) or inform policies on the scientific research enterprise (policy-for-science). Some scientists prefer to engage and be neutral to the policy outcome, serving primarily as an information resource. Many may choose to also advocate for a particular outcome based on their expertise and experience. Research shows that policy decisions benefit greatly from the input of scientific experts. We explore the spectrum between informing policies in a "non-prescriptive" manner to working on policies in an advocacy space. We highlight tips for successful engagement along this spectrum. Finally, we review current science-for-policy and policy-for-science issues of relevance to the geophysical sciences.

incentives when they are more dependent on conventional sources of energy, such as coal, oil and gas or when they have the potential to produce renewable energy. The interest group influence model suggests that instrument choice is ultimately a political decision, most likely to benefit some groups more than others. The professionalism/capacity model posits that states with more professional legislatures, with legislators who make more use of policy analysis, with more capacity to generate nonpartisan policy research and with larger agencies tend to employ more and stronger instruments to stimulate renewable energy consumption and production. And last, the innovation-and-diffusion model suggests that states with a proven innovation record in climate change tend to employ more and stronger economic incentives than states without such record. Also, this model explains states' instrument choice decisions as a function of the choices made by their neighbors.

A rapid and reliable microwave extraction and the triple quadrupole-linear ion trap mass spectrometry method was developed and validated for the determination of eight alkaloids in Portulaca oleracea L. The optimal microwave extraction (MWE) condition was performed at 60 °C for 12 min with ethanol-water (70:30, v/v) as the extracting solvent, and the solvent to solid ratio was 30:1. The alkaloids were first detected simultaneously by electrospray ionization tandem mass spectrometry under positive-negative conversion multiple reaction monitor ((+/-)MRM) technique. With investigating three different columns, samples were separated in only 8 min on a Waters ACQUITY UPLC HSS T3 (50 × 2.1 mm(2), 1.8 μm) column using acetonitrile and formic acid-water solution as a mobile phase with a flow rate at 0.2 mL/min. All calibration curves showed good linearity (r>0.999) within the test ranges. The method developed was validated with acceptable sensitivity, intra- and inter-day precision, reproducibility, and extraction recoveries. It was successfully applied to the determination of eight alkaloids in Portulaca oleracea L. from different sources and different harvest periods. The method also provide a reference for extraction and determination of alkaloids in other complex systems. © 2013 Elsevier B.V. All rights reserved.

Preradiation dental extractions and the incidence of bone necrosis

International Nuclear Information System (INIS)

Beumer, J.; Harrison, R.; Sanders, B.; Kurrasch, M.

1983-01-01

Studies were done with 120 patients submitting to preradiation dental extraction within the radiation treatment volume. Bone necroses developed at the extraction sites in 17 patients (14.1%). The risk of bone necrosis in these patients is primarily dependent upon the size of the radiation treatment volume, radiation dose to mandibular bone, and healing time for the extraction wounds. Of the 13 mandibular bone necroses occurring at preradiation extraction sites, only two have not responded favorably to conservative management. Our data indicates that a policy of selected tooth removal, before radiation treatment, will minimize the risk of osteoradionecrosis. Mandibular molars with advanced chronic periodontal bone loss, residing within the proposed radiation field should be considered for removal before commencement of radiation treatment

Impact of EU agricultural policy on developing countries

DEFF Research Database (Denmark)

Boysen, Ole; Jensen, Hans Grinsted; Matthews, Alan

2016-01-01

Despite substantial reforms, the EU’s Common Agricultural Policy (CAP) is still criticised for its detrimental effects on developing countries. This paper provides updated evidence on the impact of the CAP on one developing country, Uganda. It goes beyond estimating macro-level economic effects...... by analysing the impacts on poverty. The policy simulation results show that eliminating EU agricultural support would have marginal but nonetheless positive impacts on the Ugandan economy and its poverty indicators. From the perspective of the EU’s commitment to policy coherence for development, this supports...... the view that further reducing EU Agricultural support would be positive for development....

Modern Lithuanian foreign policy: the adjustment of traditional policy

Directory of Open Access Journals (Sweden)

Batorshina Irina

2011-12-01

Full Text Available The authors consider the core areas of Lithuanian foreign policy. Special attention is paid to the adjustment of the major foreign policy vector, which concentrated earlier on the cooperation with the United States of America and strategic partnership with the Republic of Poland. The article analyses the attempts of Lithuanian president Dalia Grybauskaitė to formulate the so-called «new foreign policy» based on the multivector approach to the intergovernmental cooperation. This research is timely because of an increasing influence of small states on foreign policy decision-making within the European Union. It emphasizes the need to analyse foreign policy priorities of the Baltic States and Central and Eastern European countries and to identify the dominant trends in the international policy in the region in order to forecast further development at European and global levels. This objective is achieved with the help of an integrated approach with elements of interdisciplinary research. Special attention is paid to the comparative-historical approach, which facilitates the analysis of the relations between the Republic of Lithuania and the neighbouring states and its principal partners. Alongside traditional methods of historical research, this work employs such methods as participant observation, content and event analysis, and simultaneous and comparative analysis. The research and practical significance of this work is explained by its emphasis on the need to apply an additional theoretical framework to studies into the foreign policy initiatives of the Republic of Lithuania in the international arena. While earlier they were determined by the value (democratic approach, which was a reflection of American realism, today an increasingly important factor is the personality of the president, who does not always positively influence the changing policy of the country. The results of the research contribute substantially to the understanding of

Evaluation of urinary excretion of cortisol by radioimmunoassay through two methods (extracted and non-extracted)

International Nuclear Information System (INIS)

Fonte Kohek, M.B. da.

1992-01-01

The radioimmunoassay of urinary cortisol extracted by organic solvent (free cortisol) has been used for along time in the hypercortisolism diagnosis. With the development of more specific antisera it became possible to measure urinary cortisol without extracting it. The objective of this paper is to compare the feasibility, sensitivity and specificity of both methods (extracted versus non-extracted) in the hypercortisolism diagnosis. It was used Gamma Coat 125 I - cortisol kit provided by Clinical Assay, Incstar, US, for both methods extracting it with methylene chloride in order to measure the extracted cortisol. The sensitivity of the methods were similar (100% and 98,1%, for non-extracted and extracted methods, respectively). A positive correlation between the two methods was noticed in all groups studied (p < 0.05). It was concluded that both methods are efficient for the investigation of hypercortisolism. However, it's suggested that non-extracted urinary cortisol measurement should be the method of choice since it's an easy-to-perform and affordable method to diagnose Cushing's syndrome. (author)

Do Voters Affect Policies? Within-Coalition Competition in the Chilean Electoral System

OpenAIRE

Argote, Pablo; Navia, Patricio

2018-01-01

It has been argued that close elections lead to policy convergence, as legislators elected by a small margin are more likely to adopt moderate policy positions (Downs 1957). However, Lee, Moretti, and Butler (2004) find that electoral competition does not affect legislators’ policy preferences in the United States, questioning the median voter paradigm. To help to discern this paradox, we estimate the effect of close elections on legislators’ subsequent policy positions under different electo...

Message framing in the context of the national menu-labelling policy: a comparison of public health and private industry interests.

Science.gov (United States)

Shelton, Rachel C; Colgrove, James; Lee, Grace; Truong, Michelle; Wingood, Gina M

2017-04-01

We conducted a content analysis of public comments to understand the key framing approaches used by private industry v. public health sector, with the goal of informing future public health messaging, framing and advocacy in the context of policy making. Comments to the proposed menu-labelling policy were extracted from Regulations.gov and analysed. A framing matrix was used to organize and code key devices and themes. Documents were analysed using content analysis with Dedoose software. Recent national nutrition-labelling regulations in the USA provide a timely opportunity to understand message framing in relation to obesity prevention and policy. We examined a total of ninety-seven documents submitted on behalf of organizations (private industry, n 64; public health, n 33). Public health focused on positive health consequences of the policy, used a social justice frame and supported its arguments with academic data. Industry was more critical of the policy; it used a market justice frame that emphasized minimal regulation, depicted its members as small, family-run businesses, and illustrated points with humanizing examples. Public health framing should counter and consider engaging directly with non-health-related arguments made by industry. Public health should include more powerful framing devices to convey their messages, including metaphors and humanizing examples.

2017-12-29

A concept of using thin-layer chromatography to multicomponent sample preparation for quantitative determination of solutes followed by instrumental technique is presented. Thin-layer chromatography (TLC) is used to separate chosen substances and their internal standard from other components (matrix) and to form a single spot/zone containing them at the solvent front position. The location of the analytes and internal standard in the solvent front zone allows their easy extraction followed by quantitation by HPLC. Copyright © 2017 Elsevier B.V. All rights reserved.

Risk, Place and Oil and Gas Policy Preferences among Coloradoans

Science.gov (United States)

Mayer, Adam

Unconventional oil and gas extraction, primarily via hydraulic fracturing ("fracking"), has changed the energy landscape in the United States. The policy regime currently governing fracking is a complex patchwork in which state regulators have the primary authority. Social scientists have thoroughly documented general beliefs and risk perceptions related to fracking there is a lack of policy-related research. This dissertation examined public policy preferences for fracking regulation using a survey data from a statewide sample of Coloradoans. Theoretically, it was hypothesized that policy support hinged upon factors like risk perceptions, benefit perceptions, place attachment, community economic identity and political ideology. Overall, risk perceptions and political ideology emerged as relatively consistent and powerful predictors of support for unconventional oil and gas regulatory policy. On the other hand, several possible predictors had little to no role. Benefit perceptions had little effect on any policy dependent variable. Further, community economic identity and place attachment played very little role. I discuss policy implications and directions for future research.

Health Reform Requires Policy Capacity

Directory of Open Access Journals (Sweden)

Pierre-Gerlier Forest

2015-05-01

Full Text Available Among the many reasons that may limit the adoption of promising reform ideas, policy capacity is the least recognized. The concept itself is not widely understood. Although policy capacity is concerned with the gathering of information and the formulation of options for public action in the initial phases of policy consultation and development, it also touches on all stages of the policy process, from the strategic identification of a problem to the actual development of the policy, its formal adoption, its implementation, and even further, its evaluation and continuation or modification. Expertise in the form of policy advice is already widely available in and to public administrations, to well-established professional organizations like medical societies and, of course, to large private-sector organizations with commercial or financial interests in the health sector. We need more health actors to join the fray and move from their traditional position of advocacy to a fuller commitment to the development of policy capacity, with all that it entails in terms of leadership and social responsibility

Safe sleeping positions: practice and policy for babies with cleft palate.

Davies, Karen; Bruce, Iain A; Bannister, Patricia; Callery, Peter

2017-05-01

Guidance recommends 'back to sleep' positioning for infants from birth in order to reduce the risk of sudden infant death. Exceptions have been made for babies with severe respiratory difficulties where lateral positioning may be recommended, although uncertainty exists for other conditions affecting the upper airway structures, such as cleft palate. This paper presents research of (i) current advice on sleep positioning provided to parents of infants with cleft palate in the UK; and (ii) decision making by clinical nurse specialists when advising parents of infants with cleft palate. A qualitative descriptive study used data from a national survey with clinical nurse specialists from 12 regional cleft centres in the UK to investigate current practice. Data were collected using semi-structured telephone interviews and analysed using content analysis. Over half the regional centres used lateral sleep positioning based on clinical judgement of the infants' respiratory effort and upper airway obstruction. Assessment relied upon clinical judgement augmented by a range of clinical indicators, such as measures of oxygen saturation, heart rate and respiration. Specialist practitioners face a clinical dilemma between adhering to standard 'back to sleep' guidance and responding to clinical assessment of respiratory effort for infants with cleft palate. In the absence of clear evidence, specialist centres rely on clinical judgement regarding respiratory problems to identify what they believe is the most appropriate sleeping position for infants with cleft palate. Further research is needed to determine the best sleep position for an infant with cleft palate. What is Known • Supine sleep positioning reduces the risk of sudden infant death in new born infants. • There is uncertainty about the benefits or risks of lateral sleep positioning for infants with upper airway restrictions arising from cleft palate. What is New • Variability exists in the information

2018-01-01

The emerging drug resistance bacteria increased the demand on the discovery of antibiotics from natural sources. This research was aimed to study the antibacterial reactivity; as well as the phytochemicals, of the wild type of Cyclamen persicum, using nine different extraction methods where four solvents (Methanol, Ethanol, Hexane; and Water) were involved with varied extraction periods ranged from 2 up to 10 hours. The antibacterial activity of crude methanol extract (CME) was found as the best method of extraction, with particular emphasis on the method with prolonged extraction time of (10 hrs). The antibacterial activities of produced CME were determined by using agar diffusion method against two of gram-positive bacteria and two gram-negative ones. The CME treated Mueller-Hinton-Agar plates, were exhibited antibacterial effects against the gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) by showing of inhibition zone after overnight incubation, while nothing was noticed on those of gram negative ones (Pseudomonas aeruginosa and Escherichia coli). These results that proved the antibacterial activity of the Cyclamen persicum tubers were positively tested the Saponin glycosides from plant. In addition to that, methanol solvent could be the useful method for extractions of Cyclamen and can be used in any developing drugs against pathogenic gram positive bacteria.

Climate, Companies, and Public Policy: How Transparent Is the Private Sector in Reporting Climate Policy Influence?

Science.gov (United States)

Goldman, G. T.; Carlson, C.

2014-12-01

To enact effective policies to address climate change, decision makers need both scientific and political support. One major barrier to U.S. climate policy enactment has been the opposition of private sector actors to proposed policies and to climate science itself. Increasingly, the public and investors are holding companies accountable for their actions around climate change—including political activies, affiliations with trade groups, and involvement with climate science. However, this accountability is inhibited by the prominent role that trade associations have played in climate policy debates in recent years. The opaque nature of such groups is problematic, as it inhibits the public from understanding who is obstructing progress on addressing climate change, and in some cases, impedes the public's climate literacy. Voluntary climate reporting can yield some information on companies' climate engagement and demonstrates the need for greater transparency in corporate political activities around climate change. We analyze CDP climate reporting data from 1,824 companies to assess the degree to which corporate actors disclosed their political influence on climate policies through their trade associations. Results demonstrate the limitations of voluntary reporting and the extent to which companies utilize their trade associations to influence climate change policy debates without being held accountable for these positions. Notably, many companies failed to acknowledge their board seat on trade groups with significant climate policy engagement. Of those that did acknowledge their board membership, some claimed not to agree with their trade associations' positions on climate change. These results raise questions about who trade groups are representing when they challenge the science or obstruct policies to address climate change. Recommendations for overcoming this barrier to informed decision making to address climate change will be discussed.

Canada's uranium policies

International Nuclear Information System (INIS)

Smith, K.L.; Williams, R.M.

1991-01-01

The purpose of this paper is to provide an update on the Canadian Government policies which affect the uranium industry and, where appropriate, to provide some background on the development of these policies. This review is timely because of two recent announcements by the Minister of Energy, Mines and Resources - one concerning the Canadian Government's renewed commitment to maintain the nuclear power option for Canada, and the other concerning some adjustments to Canada's uranium export policy. The future of Canada's nuclear industry was subject to a thorough review by the Canadian Government during 1989. This review occurred at a time when environmental issues were attracting increasing attention around the world, and the environmental advantages of nuclear power were becoming increasingly recognised. The strong support for the nuclear industry in Canada is consistent with the government's long-standing efforts to maintain Canada's position as a reliable and competitive supplier of uranium. This paper is particularly devoted to an outline of the results of the uranium export policy review. (author)

2007-01-01

Full Text Available In this article, environmental-friendly finishing of wool fabric were processed with several water extract plants, such as hibiscus, St. John's wort, and marigold. The plant extracts have good basis in the commercial dyeing of wool, for garment and carpet industry. At the same time, the environmental-friendly finishing by water extracts plants shows very good fastness of the antimicrobial properties and coloration of wool fabric. From an ecological viewpoint, the substitution of chemical dyes with "natural products" may represent not only a strategy to reduce risk and pollutants but also an opportunity for new markets and new businesses, which can expend involving of ecology in trade policy.

3D numerical simulations of negative hydrogen ion extraction using realistic plasma parameters, geometry of the extraction aperture and full 3D magnetic field map

Decreasing the co-extracted electron current while simultaneously keeping negative ion (NI) current sufficiently high is a crucial issue on the development plasma source system for ITER Neutral Beam Injector. To support finding the best extraction conditions the 3D Particle-in-Cell Monte Carlo Collision electrostatic code ONIX (Orsay Negative Ion eXtraction) has been developed. Close collaboration with experiments and other numerical models allows performing realistic simulations with relevant input parameters: plasma properties, geometry of the extraction aperture, full 3D magnetic field map, etc. For the first time ONIX has been benchmarked with commercial positive ions tracing code KOBRA3D. A very good agreement in terms of the meniscus position and depth has been found. Simulation of NI extraction with different e/NI ratio in bulk plasma shows high relevance of the direct negative ion extraction from the surface produced NI in order to obtain extracted NI current as in the experimental results from BATMAN testbed.

In cases of bacteraemia, a rapid species identification of the causal agent directly from positive blood culture broths could assist clinicians in the timely targeting of empirical antimicrobial therapy. For this purpose, we evaluated the direct identification of micro-organisms from BacT/ALERT (bioMérieux) anaerobic positive blood cultures without charcoal using the Microflex matrix-assisted laser desorption/ionization (MALDI) time of flight MS (Bruker), after bacterial extraction by using two different methods: the MALDI Sepsityper kit (Bruker) and an in-house saponin lysis method. Bruker's recommended criteria for identification were expanded in this study, with acceptance of the species identification when the first three results with the best matches with the MALDI Biotyper database were identical, whatever the scores were. In total, 107 monobacterial cultures and six polymicrobial cultures from 77 different patients were included in this study. Among monomicrobial cultures, we identified up to the species level 67 and 66 % of bacteria with the MALDI Sepsityper kit and the saponin method, respectively. There was no significant difference between the two extraction methods. The direct species identification was particularly inconclusive for Gram-positive bacteria, as only 58 and 52 % of them were identified to the species level with the MALDI Sepsityper kit and the saponin method, respectively. Results for Gram-negative bacilli were better, with 82.5 and 90 % of correct identification to the species level with the MALDI Sepsityper kit and the saponin method, respectively. No misidentifications were given by the direct procedures when compared with identifications provided by the conventional method. Concerning the six polymicrobial blood cultures, whatever the extraction method used, a correct direct identification was only provided for one of the isolated bacteria on solid medium in all cases. The analysis of the time-to-result demonstrated a reduction

Nutrition policy in whose interests? A New Zealand case study.

In the context of the global obesity epidemic, national nutrition policies have come under scrutiny. The present paper examines whose interests - industry or public health - are served by these policies and why. Using an exemplary case study of submissions to an inquiry into obesity, the research compared the positions of industry and public health groups with that taken by government. We assessed whether the interests were given equal consideration (a pluralist model of influence) or whether the interests of one group were favoured over the other (a neo-pluralist model). 2006 New Zealand Inquiry into Obesity. Food and advertising industry and public health submitters. The Government's position was largely aligned with industry interests in three of four policy domains: the national obesity strategy; food industry policy; and advertising and marketing policies. The exception to this was nutrition policy in schools, where the Government's position was aligned with public health interests. These findings support the neo-pluralist model of interest group influence. The dominance of the food industry in national nutrition policy needs to be addressed. It is in the interests of the public, industry and the state that government regulates the food and advertising industries and limits the involvement of industry in policy making. Failure to do so will be costly for individuals, in terms of poor health and earlier death, costly to governments in terms of the associated health costs, and costly to both the government and industry due to losses in human productivity.

Political rhetoric from Canada can inform healthy public policy argumentation.

Patterson, Patrick B; McIntyre, Lynn; Anderson, Laura C; Mah, Catherine L

2017-10-01

Household food insecurity (HFI), insufficient income to obtain adequate food, is a growing problem in Canada and other Organisation of economic cooperation and development (OECD) countries. Government political orientations impact health policies and outcomes. We critically examined Canadian political rhetoric around HFI from 1995 to 2012 as a means to support effective healthy public policy argumentation. We analysed a data set comprised of Hansard extracts on HFI from the legislative debates of the Canadian federal and three provincial governments, using thematic coding guided by interpretivist theories of policy. Extracts were examined for content, jurisdiction, the political affiliation of the legislator speaking and governing status. Members of non-governing, or 'opposition' parties, dominated the rhetoric. A central hunger-as-poverty theme was used by legislators across the political spectrum, both in government and in opposition. Legislators differed in terms of policy approach around how income should flow to citizens facing HFI: income intervention on the left, pragmatism in the centre, reliance on markets on the right. This analysis is a case-example from Canada and caution must be exercised in terms of the generalizability of findings across jurisdictions. Despite this limitation, our findings can help healthy public policy advocates in designing and communicating HFI policy interventions in OECD countries with a similar left-right spectrum. First, even with a divisive health policy issue such as actions to address HFI, core themes around poverty are widely understood. Secondly, the non-polarizing centrist, pragmatist, approach may be strategically valuable. Thirdly, it is important to treat the rhetoric of opposition members differently from that of government members. © The Author 2016. Published by Oxford University Press. All rights reserved.

Anticipating the uncertain: economic modeling and climate change policy

Energy Technology Data Exchange (ETDEWEB)

Jensen, Svenn

2012-11-01

With this thesis I wish to contribute to the understanding of how uncertainty and the anticipation of future events by economic actors affect climate policies. The thesis consists of four papers. Two papers are analytical models which explicitly consider that emissions are caused by extracting scarce fossil fuels which in the future must be replaced by clean technologies. The other two are so called numerical integrated assessment models. Such models represent the world economy, the climate system and the interactions between those two quantitatively, complementing more abstract theoretical work. Should policy makers discriminate between subsidizing renewable energy sources such as wind or solar power, and technologies such as carbon capture and storage (CCS)? Focusing only on the dynamic supply of fossil fuels and hence Co{sub 2}, we find here that cheaper future renewables cause extraction to speed up, lower costs of CCS may delay it. CCS hence may dampen the dynamic inefficiency caused by the absence of comprehensive climate policies today. Does it matter whether uncertainty about future damage assessment is due to scientific complexities or stems from the political process? In paper two, I find that political and scientific uncertainties have opposing effects on the incentives to investment in renewables and the extraction of fossil fuels: The prospect of scientific learning about the climate system increases investment incentives and, ceteris paribus, slows extraction down; uncertainty about future political constellations does the opposite. The optimal carbon tax under scientific uncertainty equals expected marginal damages, whereas political uncertainty demands a tax below marginal damages that decreases over time. Does uncertainty about economic growth impact optimal climate policy today? Here we are the first to consistently analyze how uncertainty about future economic growth affects optimal emission reductions and the optimal social cost of carbon. We

Mayer, M.

2006-01-01

Whether the People's Republic of China may develop to an economical super-government in future depends on the amount of power and resources of this land. The security of power supply is in an extremely prominent position in the Agenda of the Chinese government. Under this aspect the author of the contribution under consideration reports on the power policy of China. The main aspects of this contribution are: (a) Trends of power consumption, productions and imports of power; (b) Power political targets, measures and instruments of China; (c) Characteristics, national and international impacts of the power policy of China. Due to the economical activities of the chinese oil industry worldwide as well as due to the increasing dependence from imports of petroleum and natural oil, China becomes a global player. Thus, one may expect an intensification of Beijing's economical activities with an increased military component. Nevertheless, the power policy of China is an important factor in the global competition according to fossil resources. In order to understand the future behaviour of China's power policy, one may have to take notice of the strategies relating the power policy and relating to foreign affairs. Furthermore, trends and problematic areas concerning the securitization of the power supply in the national area have to be observed

Energy policy under the aspect of international economic interdependencies

Michaelis, H.

1978-01-01

A few introductory remarks on the status of and on prospects fo the world energy economy as well as on reasons given for the necessity of a world-wide coordination of energy policy and economic policy are followed by an explanation of the policy led by oil extracting countries and of the endeavour of western industrialized countries to reduce oil imports. Even if the state of utilizing nuclear energy does not yet present a sufficient alternative, the international nuclear energy continues to be directed towards this goal. Seen from an international viewpoint, relieving contributions are to be expected from energy-conservation-actions and from the development of regenerative energy sources. (UA) [de

(i) Evaluation of delayed time to blood culture extraction by the Sepsityper kit and impact of shipping pellets off-site for MALDI-TOF MS analysis. (ii) Comparison of Sepsityper and laboratory-developed extraction methods from a literature review. Using two blood culture systems (BD BACTEC and VersaTREK), we extracted 411 positive blood cultures using the Sepsityper kit to mimic a potential protocol for institutions without a MALDI-TOF MS. Extracted pellets were shipped and analysed on the Bruker UltraflexIII. Successful extraction of 358 (87·1%) samples was determined by the presence of detectable proteins. MALDI-TOF MS correctly identified 332 (80·8%) samples. Delayed time to extraction did not affect Sepsityper extraction or MALDI-TOF MS accuracy. The extracted pellets remain stable and provide accurate results by MALDI-TOF MS when shipped at room temperature to off-site reference laboratories. This is the first study to show that institutions without a MALDI-TOF MS can take advantage of this innovative technology by shipping a volume of blood to an off-site laboratory for extraction and MALDI-TOF MS analysis. We also performed a literature review to compare various extraction methods. © 2014 The Society for Applied Microbiology.

Full Text Available This study investigated school administrators’ perceptions of school improvement policies in a high-impact policy environment by measuring the impact of accountability, site-based management, professional development, and scheduling reform on the three dependent variables of a academic outcomes, b staff morale, and c parent and community involvement. Using a convenience sampling method, 49 public school principals from Texas participated and an online survey was constructed to gather both quantitative (i.e., Likert scale and qualitative (i.e., open ended response data. The findings clearly point to principals, regardless of geographical district type and grade level school type, viewing less controversial and more intrinsically oriented policies (i.e., site-based management and professional development as having a greater positive impact on outcomes as a whole than more radical alternatives (i.e., accountability and time and schedule reform. The evidence suggests that more aggressive school improvement policy approaches are likely failing to generate enough convincing outcomes to generate high commitment and confidence from school leaders. Further studies may look at the interaction of policy impact with minority student enrollments and with subgroup populations.

Position Paper. Safety for K-12 students: United States policy concerning LGBT student safety must provide inclusion

2013-07-01

Full Text Available Students who identify as lesbian, gay, bisexual, or transgender (LGBT are at risk for harassment due to their sexual orientation or gender identification with over 85% of LGBT students in the United States (US reporting such harassment. These statistics demonstrate one aspect of the significance of this issue, but the cost of human life in some instances has revealed another layer of importance related to a need for safety policies for LGBT students. Even though a need exists for such policies, the practice of heteronormativity found in US policymaking regarding bullying does not protect victims or curb the violence. This essay highlights several recent developments in anti-bullying policy in US schools that shows the existence of heteronormativity, which is not helping to pro-tect LGBT students. By understanding the discrimination encouraged by current policy, future policy can be better shaped to protect LGBT students.

Science.gov (United States)

Elhakeem, Ahmed; Cooper, Rachel; Bann, David; Hardy, Rebecca

2014-12-05

Participation in leisure-time physical activity benefits health and is thought to be more prevalent in higher socioeconomic groups. Evidence indicates that childhood socioeconomic circumstances may have long-term influences on adult health and behaviour; however, it is unclear if this extends to an influence on adult physical activity. The aim of this review is to examine whether a lower childhood socioeconomic position is associated with lower levels of leisure-time physical activity during adulthood. Keywords will be used to systematically search five online databases and additional studies will be located through a search of reference lists. At least two researchers working independently will screen search results assess the quality of included studies and extract all relevant data. Studies will be included if they are English language publications that test the association between at least one indicator of childhood socioeconomic position and a leisure-time physical activity outcome measured during adulthood. Any disagreements and discrepancies arising during the conduct of the study will be resolved through discussion. This study will address the gap in evidence by systematically reviewing the published literature to establish whether childhood socioeconomic position is related to adult participation in leisure-time physical activity. The findings may be used to inform future research and policy. PROSPERO CRD42014007063.

Electricity conservation policies and sectorial output in Pakistan: An empirical analysis

International Nuclear Information System (INIS)

Mehmood Mirza, Faisal; Bergland, Olvar; Afzal, Naila

2014-01-01

Government of Pakistan has taken several measures in recent years for conserving electricity to reduce its electricity shortfall. In this context, this study attempts to quantify the impact of different electricity conservation policies on value-added of industrial and services sectors in Pakistan. Results indicate that unanticipated shocks to electricity consumption and technical efficiency form a positive relationship while electricity price has a negative relationship with value-added in industrial and services sectors in the long run. Direct electricity conservation policies and policies that aim at increasing electricity prices will have an adverse impact on value-added of both the sectors. Policies that induce improvements in energy efficiency will have a positive impact on the sectorial output in the long run. Therefore, the government should not pursue direct consumption curtailment polices to mitigate the electricity crisis rather steps should be taken to enhance energy efficiency in the economy. This can be done by setting targets for reducing energy intensity in both the sectors. Moreover, energy efficiency should be incorporated in the mainstream of energy policy and specific laws should be enacted to establish institutions and develop methods to help in effective conservation and efficient consumption of limited energy resources. - Highlights: • We quantify impact of electricity conservation policies on sectorial value added. • Shocks to electricity consumption and technical efficiency positively affect the output. • Shocks to electricity price negatively affects value-added in the long run. • Policies inducing improvements in energy efficiency positively affect the output

Can Fiscal Policy Stimulus Boost Economic Recovery?

OpenAIRE

Agnello, L.; Sousa, R.

2011-01-01

We assess the role played by fiscal policy in explaining the dynamics of asset markets. Using a panel of ten industrialized countries, we show that a positive fiscal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the effect of fiscal policy is temporary, housing prices gradually and persistently fall. Consequently, the attempts of fiscal policy to mitigate stock price developments (e.g. via taxes on capital gains) ...

The One-Child Policy, Elder Care, and LGB Chinese: A Social Policy Explanation for Family Pressure.

Science.gov (United States)

Hildebrandt, Timothy

2018-01-03

Lesbian, gay, and bisexual (LGB) people in China consistently report family pressure as the greatest challenge they face in their daily lives. This problem has been explained primarily by highlighting sociocultural factors. While such explanations are important to understanding family pressure, they do not easily lead to actionable policy interventions to relieve it. This article suggests a new way of looking at family pressure by positing a social policy explanation. In particular, it reveals how both the one-child policy and elder care reforms have strong heteronormative biases that negatively and disproportionately affect LGB people, and it explores social policy interventions that may help address them. Beyond the China case, the article seeks to open up new avenues for research into how sexuality could be better accounted for in analyses of social policies and considered in broader discussions on defamilization and welfare state reform.

Public opinion and environmental policy output: a cross-national analysis of energy policies in Europe

Science.gov (United States)

Anderson, Brilé; Böhmelt, Tobias; Ward, Hugh

2017-11-01

This article studies how public opinion is associated with the introduction of renewable energy policies in Europe. While research increasingly seeks to model the link between public opinion and environmental policies, the empirical evidence is largely based on a single case: the US. This limits the generalizability of findings and we argue accordingly for a systematic, quantitative study of how public opinion drives environmental policies in another context. Theoretically, we combine arguments behind the political survival of democratic leaders with electoral success and environmental politics. Ultimately, we suggest that office-seeking leaders introduce policies that seem favorable to the domestic audience; if the public prefers environmental protection, the government introduces such policies in turn. The main contribution of this research is the cross-country empirical analysis, where we combine data on the public’s environmental attitudes and renewable energy policy outputs in a European context between 1974 and 2015. We show that as public opinion shifts towards prioritizing the environment, there is a significant and positive effect on the rate of renewable energy policy outputs by governments in Europe. To our knowledge, this is the first systematic, quantitative study of public opinion and environmental policies across a large set of countries, and we demonstrate that the mechanisms behind the introduction of renewable energy policies follow major trends across European states.

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

US National energy policy: conservation and environment

Michna, J.; Bednarz, L.M.

2004-01-01

The paper presents extracts from an extended review devoted to recent changes and current trends in the national energy policy pursued in the USA. In 2001 the President Bush proposed an energy strategy for the period to 2025 that would promote energy conservation, repair and expand energy infrastructure, and increase energy supply while protecting the environment. The material stresses the importance of a sound national energy policy addressing supply, energy distribution and conservation. Well - illustrated data are given on the energy production and consumption (total, per capita, per $, by category, by fuel, etc.) and on the emissions (by sector, by fuel, by region, etc.). Giving an accurate account of the current situation with energy in America and a vision of its development for the first quarter of our century, these data are helpful for analyzing the national energy policies in other countries, post - transitional included.

State health agencies and the legislative policy process.

Science.gov (United States)

Williams-Crowe, S M; Aultman, T V

1994-01-01

A new era of health care reform places increasing pressure on public health leaders and agencies to participate in the public policy arena. Public health professionals have long been comfortable in providing the scientific knowledge base required in policy development. What has been more recent in its evolution, however, is recognition that they must also play an active role in leading and shaping the debate over policy. A profile of effective State legislative policy "entrepreneurs" and their strategies has been developed to assist health agencies in developing such a leadership position. Based on the experiences of State legislative liaison officers, specific strategies for dealing with State legislatures have been identified and are organized into five key areas--agency organization, staff skills, communications, negotiation, and active ongoing involvement. A public health agency must be organized effectively to participate in the legislative policy process. Typically, effective agencies centralize responsibility for policy activities and promote broad and coordinated participation throughout the organization. Playing a key role in the agency's political interventions, the legislative liaison office should be staffed with persons possessing excellent interpersonal skills and a high degree of technical competence. Of central importance to effective legislative policy entrepreneurship is the ability to communicate the agency's position clearly. This includes setting forward a focused policy agenda, documenting policy issues in a meaningful manner, and reaching legislators with the proper information. Once a matter is on the legislative agenda, the agency must be prepared to negotiate and build broad support for the measure. Finally, public health agencies must be active policy players. To take advantage of new opportunities for action, the public health (policy) leader must monitor the political environment continually.By working to anticipate and formulate

Effect of metal salts on antibacterial activity of zingiber officinale roscoe extract

International Nuclear Information System (INIS)

Sohail, T.; Yaqeen, Z.; Imran, H.; Rehman, Z.; Fatima, N.

2013-01-01

The antibacterial activity of ethanol extract of Zingiber Officinale Roscoe (ginger) and its combination with different salts like CuSO/sub 4/, ZnSO/sub 4/ and MnCl/sub 2/ was investigated. Both Gram positive and Gram negative bacteria were tested by agar diffusion method. The results showed that ethanol extract of Zingiber Officinale gave the maximum zone of inhibition at 50 mg/ml concentrations against Escherichia coli among Gram negative bacteria and against Staphylococcus aureus in Gram positive bacteria. However antibacterial activity of the ginger and metal salts combination was greater than activity of ethanol extract. These investigations indicate that though ethanol extract has antibacterial activity against Gram positive and Gram negative bacteria, ginger and metal salts complex has more inhibitory effect on microorganisms. Antibacterial activity was also compared with standard drug ampicillin. The minimum inhibitory concentration (MIC) of ginger extract and metal salts complexes against all test organisms ranged from 0.3125 to 2.5 mg/ml. (author)

Climate policy: Bucket or drainer?

International Nuclear Information System (INIS)

Oikonomou, Vlasis; Patel, Martin; Worrell, Ernst

2006-01-01

Worldwide, industry is responsible for about 40% of greenhouse gas (GHG) emissions, making it an important target for climate policy. Energy-intensive industries may be particularly vulnerable to higher energy costs caused by climate policy. If companies cannot offset rising energy costs and would face increased competition from countries without climate policy, they may decide to relocate their industrial production to the countries without climate policy. The resulting net effect of climate policy on GHG emissions in foreign countries is typically referred to as 'carbon leakage'. Carbon leakage may lead to higher global GHG emissions due to the use of less advanced technology in less developed countries. Based on a literature review of climate policy, earlier environmental policy and analyses of historical trends, this paper assesses the carbon leakage effects of climate policy for energy-intensive industries. Reviews of past trends in production location of energy-intensive industries show an increased global production share of Non-Annex 1 countries. However, from empirical analyses we conclude that the trend is primarily driven by regional demand growth. In contrast, climate policy models show a strong carbon leakage. Even though future climate policy may have a more profound impact than environmental policies in the past, the modelling results are doubtful. Leakage generally seems to be overestimated in current models, especially as potential positive spillovers are often not included in the models. The ambiguity of the empirical analyses and the modelling results warrants further research in the importance of production factors for relocation

Student voice: An emerging discourse in Irish education policy

Directory of Open Access Journals (Sweden)

Domnall Fleming

2015-09-01

Full Text Available In positioning student voice within the Irish education policy discourse it is imperative that this emergent and complex concept is explored and theorized in the context of its definition and motivation. Student voice can then be positioned and critiqued as it emerged within Irish education policy primarily following Ireland’s ratification of the United Nations Charter on the Rights of the Child (UNCRC in 1992. Initially emerging in policy from a rights-based and democratic citizenship perspective, the student council became the principal construct for student voice in Irish post-primary schools. While central to the policy discourse, the student council construct has become tokenistic and redundant in practice. School evaluation policy, both external and internal, became a further catalyst for student voice in Ireland. Both processes further challenge and contest the motivation for student voice and point to the concept as an instrument for school improvement and performativity that lacks any centrality for a person-centered, rights-based, dialogic and consultative student voice within an inclusive classroom and school culture.

Government policy uncertainty and stock prices: The case of Australia's uranium industry

International Nuclear Information System (INIS)

Ferguson, Andrew; Lam, Peter

2016-01-01

We investigate effects of government policy uncertainty on stock prices, reflecting tension between ‘private interest’ (economic benefits) and ‘public interest’ arguments over uranium mining. Using a sample of Australian-listed uranium firms from January 2005 through June 2008, we document a positive contemporaneous correlation between stock returns and volatility and two measures of government policy uncertainty, proxied by the spread in voters' opinion polls between the two major political parties and a news-based sentiment index. Event-study results show significant stock price reactions to key uranium-related policy events, with cross-sectional variation in event returns predicted by models incorporating firm- and project-level characteristics. Our research design and findings may inform future research on the capital market effects of government policy uncertainty in other regulated industries. - Highlights: • Government policy uncertainty has direct effects on stock prices of uranium explorers. • Stock returns are positively related to the spread in two-party-preferred voting intention. • Stock volatility is positively related to a uranium news-based sentiment index. • Event-study results show significant market reaction to key uranium policy events.

Hexane neem leaf extract more potent than ethanol extract against Aspergillus flavus

Directory of Open Access Journals (Sweden)

Jenny Hidayat

2015-12-01

Full Text Available BACKGROUND Aspergillus flavus is one of the causes of aspergillosis, with a high virulence and resistance to standard antifungals, resulting in a high mortality rate. Medicinal plants are increasingly used as they are relatively safer with minimal side effects. Previously we found that the ethanol extract of neem (Azadirachta indica A Juss leaves inhibits A. flavus growth in vitro. However, most chemical compounds with antifungal effect are nonpolar. The purpose of this research was to compare the antifungal effect of neem leaves extracted in a nonpolar solvent to that of leaves extracted in a polar solvent. METHODS An in vitro experimental research was conducted between October 2013 and January 2014. Neem leaves were extracted in ethanol or hexane at various concentrations. A macrodilution test with 48-hour incubation time was done in triplicate on 8 groups of samples. These comprised the neem leaf ethanol extract (NLEE at 0.5, 1.0, and 2.0 g/dL, neem leaf hexane extract (NLHE at 0.5, 1.0, and 2.0 g/dL, positive control, and negative control groups. Fungal growth was detected on Sabouroud dextrose agar. Statistical analysis used Chi square and Fisher’s exact test. RESULTS NLHE had a higher, but statistically non-significant, inhibitory effect on A. flavus than NLEE (p=0.996. At higher concentrations, the antifungal effect of NLHE is better than that of NLEE. CONCLUSION There is no significant difference in in-vitro inhibitory effectivity on A. flavus of neem leaves between extracts in polar and nonpolar solvents.

Regime change and public policy: the political and macro-economic decision-making of Spanish energy policy

Energy Technology Data Exchange (ETDEWEB)

Lancaster, T.D.

1983-01-01

This dissertation examines the effects of peaceful regime change on public policy-making. Spain's National Energy Plan (PEN) in particular, and energy planning in general, constitute a critical policy issue which permits direct comparison of decision-making across regime change from the Franco dictatorship to the present constitutional monarchy. The research reveals that the nature of the political coalition underlying Spain's regime change accounts of the lack of significant change in policy-making processes in this particular policy issue. This thesis develops a two-pronged argument to explain the absence of significant policy change. The first is based on a general view of the Franco regime's and the democratic system's coalitional support. In each, three major political forces are seen as central: the military, business, and labor. One of these, business, is seen as being pivotal in the regime transition. Business' pivotal position, it is argued, has permitted a defence of a national energy policy beneficial to its economic interests in energy. The argument's second part focuses on the binding constraint on policy outcomes imposed by private interests in state planning and the generally non-binding nature of oppositional party policy proposals and public opinion.

State Policies Influence Medicare Telemedicine Utilization.

Medicare policy regarding telemedicine reimbursement has changed little since 2000. Many individual states, however, have added telemedicine reimbursement for either Medicaid and/or commercial payers over the same period. Because telemedicine programs must serve patients from all or most payers, it is likely that these state-level policy changes have significant impacts on telemedicine program viability and utilization of services from all payers, not just those services and payers affected directly by state policy. This report explores the impact of two significant state-level policy changes-one expanding Medicaid telemedicine coverage and the other introducing telemedicine parity for commercial payers-on Medicare utilization in the affected states. Medicare claims data from 2011-2013 were examined for states in the Great Lakes region. All valid claims for live interactive telemedicine professional fees were extracted and linked to their states of origin. Allowed encounters and expenditures were calculated in total and on a per 1,000 members per year basis to standardize against changes in the Medicare population by state and year. Medicare telemedicine encounters and professional fee expenditures grew sharply following changes in state Medicaid and commercial payer policy in the examined states. Medicare utilization in Illinois grew by 173% in 2012 (over 2011) following Medicaid coverage expansion, and Medicare utilization in Michigan grew by 118% in 2013 (over 2012) following adoption of telemedicine parity for commercial payers. By contrast, annual Medicare telemedicine utilization growth in surrounding states (in which there were no significant policy changes during these years) varied somewhat but showed no discernible pattern. Although Medicare telemedicine policy has changed little since its inception, changes in state policies with regard to telemedicine reimbursement appear to have significant impacts on the practical viability of telemedicine programs

Soviet Marxism and population policy.

Science.gov (United States)

Vonfrank, A

1984-01-01

American demographers have maintained that Marxism, notably Soviet Marxism, is consistently pronatalist. The Soviet view is said to be that population growth is not a problem and that birth control policies in either developed or developing societies are to be rejected; the "correct" (i.e., socialist) socioeconomic structure is the true solution to alleged population problems. Such representations of Soviet thought greatly oversimplify the Soviet position as well as fail to discern the changes in Soviet thought that have been occurring. Since the 1960s Soviet writers have increasingly acknowledged that population growth is, to a considerable degree, independent of the economic base of society and that conscious population policies may be needed to either increase or decrease the rate of population growth. Even socialist societies can have population problems. And where population growth is too rapid, as in the developing countries, policies to slow such growth are needed because of the threat to economic development. However, the Soviets continue to stress that birth control policies must go hand-in-hand with social and economic development policies if they are to be effective.

Macroprudential policies on banking system

Full Text Available The macro-prudential tool kit deals with those risks that contributed to the outbreak of the last economic crisis or materialized during it, namely the excessive credit growth, the excessive price assets growth driven by the credit growth, the excessive increase in leverage, the liquidity risk, the volatile capital flows and foreign currency lending. It can be argued that macro-prudential policies underestimated the systemic risks mentioned, although they were better positioned than other policies aimed at financial stability. The impact of macro-prudential policy is difficult to be determined, because is usually applied simultaneously and in the same direction with other macroeconomic policies. Thus, it is necessary a better coordination of policies and a better calibration of instruments in order to get a quick and effective response during their implementation. These must be in line with national specificities and the risks identified. Until the new macro-prudential tools introduced by Basel III will prove their effectiveness, the issue of finding proper tools is still open.

2014-01-01

The antimicrobial effect of 24 different hydroalcoholic extracts (100, 75, 50 and 25% methanol and water) obtained from four parts (leaf+stem (aerial), peel, pulp and seed) of Momordica charantia L. were investigated against five Gram-positive, six Gram-negative and four fungal strains. The extraction was done by individual cold percolation method using hexane, different hydroalcoholic solvent (100, 75, 50 and 25% methanol) and water. The antimicrobial activity was done by agar well diffusion assay. The extracts, which showed >15 mm zone of inhibition, were further screened to determine minimum inhibitory concentration and minimum bactericidal concentration using a broth dilution method performed in 96-well microtitre plate. The extractive yield was highest in aqueous extracts of all the four parts closely followed by 25% methanol. Micrococcus flavus was the most susceptible Gram-positive bacteria and Pseudomonas testosteroni was the most susceptible Gram-negative bacteria. The highest antibacterial activity was shown by 100% methanol. The Gram-negative Pseudomonas spp. was more susceptible towards all the extracts than the Gram-positive bacteria or fungal strains investigated. One hundred percent and 50% methanol extracts of seed showed lowest minimum inhibitory concentration and minimum bactericidal concentration values, that is <39 and 625 μg/ml, respectively, against Pseudomonas pictorum. Therefore, these extracts would be of interest in the control of Pseudomonas spp. in food industry as well as used for therapeutic purposes. PMID:24843188

In the present work, vacuum microwave-assisted extraction (VMAE) was to perform microwave-assisted extraction in vacuum. Two well-known antioxidants, vitamin C from guava and green pepper, and vitamin E (alpha-tocopherol and gamma-tocopherol) from soybean and tea leaves, which were easy to be oxidized, were chosen as representative target compounds for the evaluation of VMAE. The extraction yields of vitamin C, alpha-tocopherol and gamma-tocopherol in VMAE and those in MAE performed in atmosphere (air-MAE) were compared and the effects of extraction time, extraction temperature and sample matrix were studied. Moreover, the effects of the oxygen and subpressure invacuo were also discussed via performed MAE in N(2) atmosphere (N(2)-MAE). The extraction yields of vitamin C, alpha-tocopherol and gamma-tocopherol in VMAE were higher than that in air-MAE, 35% increments of vitamin C from green pepper, 22% increments of alpha-tocopherol and 47% increments of gamma-tocopherol from tea leaves were obtained, respectively. The comparable increased extraction yields of vitamin C, alpha-tocopherol and gamma-tocopherol in N(2)-MAE to that in air-MAE confirmed that oxygen in system was the crucial factor for the oxidation of vitamin C and vitamin E, VMAE was beneficial for the extraction of these oxygen-sensitive compounds. In addition, the subpressure invacuo in the VMAE system also showed positive affect on the extraction yields. On the basis of preventing oxidation and improving extraction efficiency of target compounds because of less oxygen and subpressure invacuo in the extraction system, VMAE has good potential for the extraction of oxygen-sensitive and thermosensitive compounds from plant samples.

Full Text Available The article is aimed at researching the contradictions associated with the use of the term of «accounting policy» in Ukraine. It is displayed that in normative documents the formulation of accounting policy does not always meet the requirements of the system of international standards. As a result, accounting policies are often being understand as the measures that are actually related to the accounting organization; an accounting policy is established not only for financial accounting and reporting, but also (not always justified for the managerial and tax accounting. It has been proved that the current accounting policy has not only positive but also negative aspects for the national accounting system.

Current approaches to the European Health Policy

Anda CURTA

Full Text Available The purpose of this paper is to identify the key elements that define the new European health policy. We observed that the health policy actually appeared to be an enclave within the integration process. The development of health policy in the new Member States followed a common pattern. Therefore, the European health policy reflected a general desire on behalf of the members to have more clarity of the rules in this area, given the different interpretation of the rules by different Member States.The Lisbon Treaty does not bring substantive changes regarding the public health policy, therefore the Member States shall keep their competence in defining the organization and financing this domain. However, the EU2020 Strategy states that “Europe faces a moment of transformation”. Therefore, the “Europeanization” of health policy could lead to the positive developments that all EU citizens are expecting.

Analyzing the Safeguarding Our Communities Act: Patch for Patch Return Policy in Ontario

Full Text Available Fentanyl is prescribed to patients suffering from severe chronic pain. Transdermal patches are the best mode of delivery for patients who have developed tolerance for opioids. However, used patches still contain fentanyl that can be extracted and misused, with potentially severe consequences. To address this issue, patients who are prescribed fentanyl patches in Ontario are now required to return previously dispensed patches to receive new patches under the Safeguarding Our Communities Act: Patch for Patch (P4P Return Policy. The problem is significant in Ontario because the province has the largest annual dispense rate of high-dose prescription fentanyl (112 units per 1,000 population in Canada even though the prevalence rate of chronic pain is lower than the national reported range (16.6% in Ontario versus 19.6 to 21.9% in other provinces, according to Gomes et al. 2014. The primary goal of this reform is to instill responsible use of fentanyl patches, and to improve safety for patients and the public by having a central disposal process. The reform was modeled after a community initiative that was pioneered in North Bay after receiving great support from health professional colleges and communities that voluntarily integrated the program prior to the introduction of Bill 33. Preliminary data suggest that the P4P policy is positively received by health professionals, although ongoing evaluation is needed to assess the effectiveness of the policy in reducing misuse and abuse of prescribed fentanyl patches.

Alternative policies to subsidize rural household biogas digesters

Wang, Changbo; Zhang, Yaoqi; Zhang, Lixiao; Pang, Mingyue

2016-01-01

Existing policies of household biogas projects focus mainly on supports on construction, but less consider management and maintenance, resulting in high scrap rate and waste of resources. Alternative policies must be explored to balance construction and operation. Taking the costs and benefits from a typical rural household biogas project, this paper assesses the economic performance at three different subsidy levels, i.e., no subsidy, existing standard and positive externality based standard. Furthermore three subsidy alternatives, one-time, annual and combined option are applied to the externality based standard. The results show that household biogas digesters have unsatisfactory economic performance without any subsidy and even in current subsidy policies. Environmental benefits of the digester were estimated as 2732 Chinese Yuan, significantly larger than existing subsidy standard. To keep continuous work during the 20-year lifespans of digesters, the income disparity of farmers among regions must be considered for policy application. With the increasing of labor costs, the ratio of initial subsidies must be reduced. These results provide policy implications to the future development of biogas projects in terms of both their construction and follow-up management, reuse of the abandoned digesters as well as the exploitation of other emerging renewable energy projects. - Highlights: •Cost-benefit analysis of biogas was conducted involving its positive externalities. •Current subsidy level and scheme discourages sustained biogas use. •Biogas subsidy level should be raised based on the value of positive externalities. •Regionalized subsidy system is needed to address the current inefficiency.

U.S. state policies for renewable energy: Context and effectiveness

Delmas, Magali A.; Montes-Sancho, Maria J.

2011-01-01

Over the past decade, state policies on renewable energy have been on the rise in the U.S., providing states with various options for encouraging the generation of renewable electricity. Two promising policies, the Renewable Portfolio Standard (RPS) and the Mandatory Green Power Option (MGPO), have been implemented in many states but the evidence about their effectiveness is mixed. In this paper, we argue that recognizing the natural, social, and policy context under which MGPO and RPS are adopted is necessary in order to measure their true effectiveness. This is because the context rather than the policy might lead to positive outcomes and there is the possibility for sample bias. When controlling for the context in which the policies are implemented, we find that RPS has a negative impact on investments in renewable capacity. However, we find that investor-owned utilities seem to respond more positively to RPS mandates than publicly owned utilities. By contrast, MGPO appears to have a significant effect on installed renewable capacity for all utilities regardless of the context in which it is implemented. - Research highlights: → We assess whether U.S. state renewable policies are effective at generating investments in renewable capacity. → We find that Renewable Portfolio Standard (RPS) is ineffective. → We find that Mandatory Green Power Option (MGPO) is effective. → Investor-owned utilities respond more positively to RPS than publicly owned utilities. → The results differ from previous studies because we control for sample bias.

National innovation policy and public science in Australia

Carter, Lyn

2017-12-01

In this paper, I have positioned myself with Kean Birch and explored some of the political-economic actors/actants of policy suites implicated in the biotechnologies and bioeconomy. In particular, I have considered Australia's recent National Innovation and Science Agenda and allied documents and entities (that is, Innovation and Science Australia, the National Science Statement and the 2016 National Research Infrastructure Roadmap) as one of the National Innovation Strategies in place now in OECD countries and beyond. In overview, these policy suites utilise the same high knowledge creation/low translation and commericalisation arguments as elsewhere to press for particular ideologically based `improvements' to public science. Mapping the terrain of these entities has revealed the innovation, biotechnology and bioeconomy policy space to be inordinately complex and challenging to navigate. Reviewing Australia's position enables the type of comparative work that contributes to a closer understanding of the largely neoliberal global economic imperatives shaping contemporaneity. Moreover, while these policy suites attempt to constitute and circulate particular visions of science education, their complex nature mitigates against science teachers/educators grappling with their implications.

International perceptions of US nuclear policy.

Energy Technology Data Exchange (ETDEWEB)

Stanley, Elizabeth A. (Georgetown Universtiy, Washington, DC)

2006-02-01

The report presents a summary of international perceptions and beliefs about US nuclear policy, focusing on four countries--China, Iran, Pakistan and Germany--chosen because they span the spectrum of states with which the United States has relationships. A paradox is pointed out: that although the goal of US nuclear policy is to make the United States and its allies safer through a policy of deterrence, international perceptions of US nuclear policy may actually be making the US less safe by eroding its soft power and global leadership position. Broadly held perceptions include a pattern of US hypocrisy and double standards--one set for the US and its allies, and another set for all others. Importantly, the US nuclear posture is not seen in a vacuum, but as one piece of the United States behavior on the world stage. Because of this, the potential direct side effects of any negative international perceptions of US nuclear policy can be somewhat mitigated, dependent on other US policies and actions. The more indirect and long term relation of US nuclear policy to US international reputation and soft power, however, matters immensely to successful multilateral and proactive engagement on other pressing global issues.

A policy synthesis approach for slowing global warming

International Nuclear Information System (INIS)

Timilsina, G.R.

1996-01-01

Global warming is a burning environmental issue today but confronting with subjective as well as policy conflicts. The findings of various studies indicate that developed countries that are capable of affording effective measures towards the global warming mitigation have fewer incentives for doing so because they will have a minimal damage from global warming. The developing countries, although they will have greater damage, are unlikely to divert their development budget for taking preventive actions towards global warming. The only solution in this situation is to design a policy that encourages all the nation in the world to participate in the programs for slowing global warming. Without active participation of all nations, it seems unlikely to reduce the global warming problem in an effective way. This study presents a qualitative policy recommendation extracted from a comprehensive analysis of the findings of several studies conducted so far in this field. This study has categorized the policy approaches for mitigating the global warming in three groups: Engineering approach, forestry approach and economic approach

Authorship policies of scientific journals.

Resnik, David B; Tyler, Ana M; Black, Jennifer R; Kissling, Grace

2016-03-01

We analysed the authorship policies of a random sample of 600 journals from the Journal Citation Reports database. 62.5% of the journals we sampled had an authorship policy. Having an authorship policy was positively associated with impact factor. Journals from the biomedical sciences and social sciences/humanities were more likely to have an authorship policy than journals from the physical sciences, engineering or mathematical sciences. Among journals with a policy, the most frequent type of policy was guidance on criteria for authorship (99.7%); followed by guidance on acknowledgments (97.3%); requiring that authors make substantial contributions to the research (94.7%); requiring that authors be accountable for the research as a whole (84.8%); guidance on changes in authorship (77.9%); requiring that authors give final approval to the manuscript (77.6%); requiring that authors draft or critically revise the manuscript (71.7%); providing guidance on corporate authorship (58.9%); prohibiting gift, guest or ghost authorship (31.7%); requiring authors to describe their contributions (5.3%); limiting the number of authors for some types of articles (4.0%) and requiring authors to be accountable for their part in the research (1.1%). None of the policies addressed equal contribution statements. Journals that do not have authorship policies should consider adopting or developing ones. Published by the BMJ Publishing Group Limited.

The virtual cathode: Key to the numerical simulation of negative ion extraction

International Nuclear Information System (INIS)

Becker, R.; Leung, K.N.; Kunkel, W.

1998-01-01

The simulation of volume produced negative ions from a plasma is by far more complicated than the extraction of positive ions, while in experiments the only difficulty seemes to be connected with the power of the electrons, which are extracted at the same time. The reason for this complication in simple minded simulations is the infinite space charge, which builds up in the turning point of the positive ions in the extraction aperture for the negative ions. Smearing out the energy of the positive ions seems to help, however, this is mostly not justified by experiments, showing a low ion energy, especially in the region between the magnetic filter and the extraction hole. This difficulty may be overcome by using experience from virtual cathode formation in magnetically focused, decelerated electron beams. The decelerated electrons behave similarly to the reflected positive ions and are forming a virtual cathode in the reflection zone. From the analysis of the electron deceleration experiment, a simple power law is deduced to describe the decreasing electron current by the local potential. In turn, this power law may also be applied to the positive ion current, resulting in simulations without space charge singularity, even in the case of monoenergetic ions. As a first step towards the numerical simulation of negative ion extraction, a linear model has been made, using this power law. The transition from a Boltzmann distribution for the plasma electrons to a truncated one for the extracted beam electrons is considered as well, parallel to Langmuir close-quote s treatment of a thermal diode for electrons. copyright 1998 American Institute of Physics

Past Fame, Present Frames and Future Flagship? An Exploration of How Health is Positioned in Canadian Foreign Policy

Canada has been regarded as a model global citizen with firm commitments to multilateralism. It has also played important roles in several international health treaties and conventions in recent years. There are now concerns that its interests in health as a foreign policy goal may be diminishing. This article reports on a thematic analysis of key Canadian foreign policy statements issued over the past decade, and interviews with key informants knowledgeable of, or experienced in the interstices of Canadian health and foreign policy. It finds that health is primarily and increasingly framed in relation to national security and economic interests. Little attention has been given to human rights obligations relevant to health as a foreign policy issue, and global health is not seen as a priority of the present government. Global health is nonetheless regarded as something with which Canadian foreign policy must engage, if only because of Canada’s membership in many United Nations and other multilateral fora. Development of a single global health strategy or framework is seen as important to improve intersectoral cooperation on health issues, and foreign policy coherence. There remains a cautious optimism that health could become the base from which Canada reasserts its internationalist status. PMID:24977037

Biophysical structure of the Ecuadorian economy, foreign trade, and policy implications

2010-01-01

At the core of this paper lays the notion that a systematic analysis of material flow accounts enables us to discuss the sustainability of an economic model. Ecuador is going through a socio-ecological transition from an agrarian towards an industrial regime, based on the use of nonrenewable sources of materials and energy. Direct material flow indicators are used in this article to analyze the ecological dimension of the economy of Ecuador during 1970-2007. This approach enables the concept of societal metabolism to become operative. The paper compares societal metabolic profiles showing that per capita use of materials is still at about one-fifth of the average in the high income countries of the world. Physical flows of trade indicate that there is an ecologically unequal exchange. Whereas a positive trade balance is desirable from an economic policy, its counterpart in physical units has been a persistent net outflow of material resources, the extraction of which causes environmental impacts and social conflicts.

Full Text Available Most of the species of Buddleja have found applications in folk medicine. This study aimed to evaluate the in vitro antimicrobial and cytotoxic potentials of B. polystachya extracts. Four extracts were prepared A-D (dichloromethane, ethyl acetate, n-butanol, and aqueous extracts, respectively. The antimicrobial activity was evaluated using the broth micro-dilution assay for minimum inhibitory concentrations (MIC. The crystal violet staining method (CVS was used for the evaluation of the cytotoxic activity on HepG-2, MCF-7 and HCT-116 human cell lines. Results showed that the highest antimicrobial activity was given by the ethyl acetate extract followed by the dichloromethane extract, while the n-butanol revealed moderate activity against gram positive bacteria only with no activity against the rest of tested microorganisms. The aqueous extract was totally ineffective against all tested microorganisms at 20 mg/ml. Among the four extracts tested, dichloromethane and ethyl acetate extracts showed the highest cytotoxic activity on all three human cell lines.

The rationale for energy efficiency policy: Assessing the recognition of the multiple benefits of energy efficiency retrofit policy

International Nuclear Information System (INIS)

Kerr, Niall; Gouldson, Andy; Barrett, John

2017-01-01

The rationale for energy efficiency policy can be framed in terms of a variety of different benefits. This paper considers how different benefits have been used within the overall rationale for energy efficient retrofit policy in different contexts. We posit that different rationales may be used for the same policy response, and that the form of rationale used may affect the design, delivery or the level of policy support, with different rationales making it easier to account for different results. Considering retrofit policy in the contexts of the UK, Germany, New Zealand and Ireland, we characterise policy rationale in each case, assessing what the key perceived benefits have been, and whether they have changed over time. The analysis identifies some marked differences between cases with the recognition of benefits and the ensuing policy rationale resulting from a complex mix of political, social and economic influences. We find that recognition of multiple benefits may not equate with multiplied policy support, and instead it is more likely that different rationales will have relevance at different times, for different audiences. The findings highlight that, alongside evidence for policy, it is important to also consider how the overall rationale for policy is eventually framed. - Highlights: • Energy efficiency as a policy issue with perceived multiple benefits. • Assessment of the influence of different benefits on rationale for energy efficient retrofit policy. • How does the rationale for retrofit policy differ in different national policy contexts. • To what extent are the perceived multiple benefits of policy recognised. • What influence does eventual rationale for policy have on the policy implemented.

There is strong evidence about which tobacco control policies reduce smoking. However, their equity impact is uncertain. The aim was to assess the effectiveness of population-level interventions/policies to reduce socioeconomic inequalities in adult smoking. Systematic review of studies of population-level interventions/policies reporting smoking-related outcomes in adults of lower compared to higher socioeconomic status (SES). References were screened and independently checked. Studies were quality assessed. Results are presented in a narrative synthesis. Equity impact was assessed as: positive (reduced inequality), neutral (no difference by SES), negative (increased inequality), mixed (equity impact varied) or unclear. 117 studies of 130 interventions/policies were included: smokefree (44); price/tax (27); mass media campaigns (30); advertising controls (9); cessation support (9); settings-based interventions (7); multiple policies (4). The distribution of equity effects was: 33 positive, 36 neutral, 38 negative, 6 mixed, 17 unclear. Most neutral equity studies benefited all SES groups. Fourteen price/tax studies were equity positive. Voluntary, regional and partial smokefree policies were more likely to be equity negative than national, comprehensive smokefree policies. Mass media campaigns had inconsistent equity effects. Cigarette marketing controls were equity positive or neutral. Targeted national smoking cessation services can be equity positive by achieving higher reach among low SES, compensating for lower quit rates. Few studies have assessed the equity impact of tobacco control policy/interventions. Price/tax increases had the most consistent positive equity impact. More research is needed to strengthen the evidence-base for reducing smoking inequalities and to develop effective equity-orientated tobacco control strategies. Copyright © 2014.

Full Text Available The cruciferous vegetables cauliflower, broccoli, cabbage, Chinese radish, Chinese kale, and Chinese kitam were used in this study to prepare water-soluble and methanol-water extracts. Crude protein extracts were also obtained by diethylaminoethyl (DEAE anion exchange chromatography. Water-soluble polysaccharides were prepared by ethanol precipitation followed by ultrafiltration. The antimicrobial effects of all these extracts were evaluated against Gram-positive bacteria, Gram-negative bacteria, and yeast. Crude protein extracts exhibited the greatest antimicrobial activity in monoculture experiments. The antimicrobial effects of cruciferous vegetables were also studied by steeping beef, carrot, and celery in chlorine (10 ppm or citric acid solution (1% containing the crude protein extract (500 ppm for different time periods. Total aerobic plate counts and coliform counts on these foods decreased significantly after 10 minutes in all steeping solutions (p < 0.05.

Methanolic extracts of flowers and leaves of Gentiana lutea L., together with the isolated compounds mangiferin, isogentisin and gentiopicrin, were used to investigate the antimicrobial activity of the plant. A variety of Gram-positive and Gram-negative bacteria as well as the yeast Candida albicans has been included in this study. Both extracts and isolated compounds showed antimicrobial activity with MIC values ranging from 0.12-0.31 mg/ml. Our study indicated that the synergistic activity of the pure compounds may be responsible for the good antimicrobial effect of the extracts. Quantification of the secondary metabolites was performed using HPLC.

Economic Policy Uncertainty and Long-Run Stock Market Volatility and Correlation

DEFF Research Database (Denmark)

Asgharian, Hossein; Christiansen, Charlotte; Hou, Ai Jun

We use Baker, Bloom, and Davis’s (2016) economic policy uncertainty indices in combination with the mixed data sampling (MIDAS) approach to investigate long-run stock market volatility and correlation, primarily for the US and UK. Long-run US–UK stock market correlation depends positively on US...... economic policy uncertainty shocks. The dependence is asymmetric, with only positive shocks - increasing uncertainty - being of importance. The US long-run stock market volatility depends significantly on US economic policy uncertainty shocks but not on UK shocks, while the UK long-run stock market...... volatility depends significantly on both. Allowing for US economic policy uncertainty shocks improves the out-of-sample forecasting of US–UK stock market correlation and enhances portfolio performance. Similar results apply to the long-run correlation between the US and Canada, China, and Germany....

Iran's petroleum policy: Current trends and the future outlook

International Nuclear Information System (INIS)

Pezeshki, S.; Fesharaki, F.

1994-12-01

The Iranian economy and political situation have undergone radical changes since the 1979 Islamic revolution. The excesses of the early years of the revolution have gradually given way to moderation and a more pragmatic economic policy--based on the principles of the free market. The petroleum policy, as a subset of the economic policies, has been somewhat affected by the political and economic developments in Iran. The petroleum policy has changed from a position of no foreign participation to a position that includes a desire for foreign participation, the text of a model contract, and an attempt to introduce new technologies in the upstream sector. This report provides an overview of the key issues facing the Iranian oil industry and the economic context in which the oil industry is operating in Iran. It describes the evolution of policies meant to move the oil industry toward the free market; it discusses Iran's oil trading partners, the outlook for refining and project investments, and current and likely future developments in the natural gas and petrochemical sectors. In short, the report provides an up-to-date assessment of the Iranian petroleum sector and its likely evolution in the future

Increased awareness, interest and use of assistive technology (AT) presents substantial opportunities for many citizens to become, or continue being, meaningful participants in society. However, there is a significant shortfall between the need for and provision of AT, and this is patterned by a range of social, demographic and structural factors. To seize the opportunity that assistive technology offers, regional, national and sub-national assistive technology policies are urgently required. This paper was developed for and through discussion at the Global Research, Innovation and Education on Assistive Technology (GREAT) Summit; organized under the auspices of the World Health Organization's Global Collaboration on Assistive Technology (GATE) program. It outlines some of the key principles that AT polices should address and recognizes that AT policy should be tailored to the realities of the contexts and resources available. AT policy should be developed as a part of the evolution of related policy across a number of different sectors and should have clear and direct links to AT as mediators and moderators for achieving the Sustainable Development Goals. The consultation process, development and implementation of policy should be fully inclusive of AT users, and their representative organizations, be across the lifespan, and imbued with a strong systems-thinking ethos. Six barriers are identified which funnel and diminish access to AT and are addressed systematically within this paper. We illustrate an example of good practice through a case study of AT services in Norway, and we note the challenges experienced in less well-resourced settings. A number of economic factors relating to AT and economic arguments for promoting AT use are also discussed. To address policy-development the importance of active citizenship and advocacy, the need to find mechanisms to scale up good community practices to a higher level, and the importance of political engagement for the

TOXICOLOGICAL DRUG SCREENING BY GC-MS VERSUS HPLC-DAD USING A COMMON EFFICIENT EXTRACTION PROCEDURE SCREENING TOXICOLOGIQUE DES MEDICAMENTS PAR HPLC-DAD ET GC-MS: PROTOCOLE D’EXTRACTION UNIQUE

Directory of Open Access Journals (Sweden)

SELOUA ELMRABEH

2015-05-01

Full Text Available This paper presents a common extraction method for toxicological drug screening by gas chromatography-mass spectrometry (GC-MS and high-performance liquid chromatography with diode-array detection (HPLC-DAD. Liquid-liquid extraction was performed using plasma of 104 samples at the Laboratory of Moroccan Poison Control and Pharmacovigilance Center during a period of 12 months. The results obtained by HPLC-DAD are compared with those determined with GC-MS. 76 cases (73.08 % were found positive for at least by one of these two techniques. HPLC-DAD identified 59.87 % of all positive results, and 10 molecules were identified only by HPLC-DAD. GC/MS identified 40.13 % of all positives, and 4 molecules were identified only by GC/MS. In order to evaluate the performance of this extraction method, an extraction yield was calculated for three classes of drugs. All the analyzed molecules were obtained in satisfactory yields (higher than 50 % except for carbamazepine, amitriptyline and nortriptyline. Overall, the results indicate that the extraction method is well adapted for toxicological drug screening. The use of common extraction simultaneously for the two techniques can reduce workload and costs of screening, while increasing the validity and reliability of the results.

The work presented in this manuscript was achieved to compare six different methods for extracting DNA from raw maize and its derived products. The methods that gave higher yield and quality of DNA were chosen to detect the genetic modification in the samples collected from the Egyptian market. The different methods used were evaluated for extracting DNA from maize kernels (without treatment), maize flour (mechanical treatment), canned maize (sweet corn), frozen maize (sweet corn), maize starch, extruded maize, popcorn, corn flacks, maize snacks, and bread made from corn flour (mechanical and thermal treatments). The quality and quantity of the DNA extracted from the standards, containing known percentages of GMO material and from the different food products were evaluated. For qualitative detection of the GMO varieties in foods, the GMOScreen 35S/NOS test kit was used, to screen the genetic modification in the samples. The positive samples for the 35S promoter and/or the NOS terminator were identified by the standard methods adopted by EU. All of the used methods extracted yielded good DNA quality. However, we noted that the purest DNA extract were obtained using the DNA extraction kit (Roche) and this generally was the best method for extracting DNA from most of the maize-derived foods. We have noted that the yield of DNA extracted from maize-derived foods was generally lower in the processed products. The results indicated that 17 samples were positive for the presence of 35S promoter, while 34% from the samples were positive for the genetically modified maize line Bt-176.

In Search for a Pronatalist Population Policy for Turkey

Yusuf YÜKSEL

2015-06-01

Full Text Available Turkey has witnessed high fertility rates and low mortality rates until 2000s. Young population structure, need for infrastructure for growing population and reproductive health issues were always on the agenda of policy makers throughout the history of Turkey. After the decline in total fertility rate below replacement level, vibrant discussions and search for a new policy framework began to be visible in the recent years. After the establishment of new Republic in Turkey in 1923 pronatalist policies were active until the beginning 1960s. After the First Development Plan in 1962, policy shift was towards an antinatalist direction until 2000. After a short period between 2000 and 2012 which can not be put any category in terms of fertility policy government clearly declared its position favouring pronatalist policies and mobilised bureaucracy for developing new policy options. This paper summarizes the fertility policies and demographic transition of Turkey and evaluates possible policy options

Recent patents on the extraction of carotenoids.

Science.gov (United States)

Riggi, Ezio

2010-01-01

This article reviews the patents that have been presented during the last decade related to the extraction of carotenoids from various forms of organic matter (fruit, vegetables, animals), with an emphasis on the methods and mechanisms exploited by these technologies, and on technical solutions for the practical problems related to these technologies. I present and classify 29 methods related to the extraction processes (physical, mechanical, chemical, and enzymatic). The large number of processes for extraction by means of supercritical fluids and the growing number of large-scale industrial plants suggest a positive trend towards using this technique that is currently slowed by its cost. This trend should be reinforced by growing restrictions imposed on the use of most organic solvents for extraction of food products and by increasingly strict waste management regulations that are indirectly promoting the use of extraction processes that leave the residual (post-extraction) matrix substantially free from solvents and compounds that must subsequently be removed or treated. None of the reviewed approaches is the best answer for every extractable compound and source, so each should be considered as one of several alternatives, including the use of a combination of extraction approaches.

New staff contract policy

HR Department

2006-01-01

Following discussion at TREF and on the recommendation of the Finance Committee, Council approved a new staff contract policy, which became effective on 1 January 2006. Its application is covered by a new Administrative Circular No. 2 (Rev. 3) 'Recruitment, appointment and possible developments regarding the contractual position of staff members'. The revised circular replaces the previous Circulars No. 9 (Rev. 3) 'Staff contracts' and No. 2 (Rev. 2) 'Guidelines and procedures concerning recruitment and probation period for staff members'. The main features of the new contract policy are as follows: The new policy provides chances for long-term employment for all staff recruits staying for four years without distinguishing between those assigned to long-term or short-term activities when joining CERN. In addition, it presents a number of simplifications for the award of ICs. There are henceforth only 2 types of contract: Limited Duration (LD) contracts for all recruitment and Indefinite Contracts (IC) for...

Impact of European policy trends on bio-energy in the Netherlands

2000-03-01

Energy extraction from biomass and waste is intended to account for a significant portion of the long-term objective of the Dutch government concerning sustainable energy. A major part of the task for energy from biomass and waste still has to come about, however. In the practical situation, the various parties in the Netherlands are experiencing different kinds of problems with this. In January 1999, the Ministry of Economic Affairs and Novern organised a round table conference concerning these bottlenecks with the participants representing a wide field of activity. The participants of this round table conference stated that insight into European policy developments is very important for the further market introduction of bio-energy in the Netherlands. Commissioned by Novem, this study surveys the consequences of the differences between European policy and Dutch policy in realising the target for energy from biomass and waste in the Netherlands in the medium term (2007). In addition, the following items were considered: sustainable energy; emission policy concerning waste, energy and biomass; waste policy and liberalisation of this market; energy policy and liberalisation of this market; agricultural policy; andfinancing of sustainable energy

The Caribbean has the highest prevalence rates of HIV/AIDS outside sub-Saharan Africa, and a broad literature suggests an ecological association between tourism areas and sexual vulnerability. Tourism employees have been shown to engage in high rates of sexual risk behaviours. Nevertheless, no large-scale or sustained HIV prevention interventions have been conducted within the tourism industry. Policy barriers and resources are under-studied. In order to identify the policy barriers and resources for HIV prevention in the tourism sector, our research used a participatory approach involving a multisectoral coalition of representatives from the tourism industry, government, public health and civil society in the Dominican Republic. We conducted 39 in-depth semi-structured interviews with policy makers throughout the country focusing on: prior experiences with HIV prevention policies and programmes in the tourism sector; barriers and resources for such policies and programmes; and future priorities and recommendations. Findings suggest perceptions among policy makers of barriers related to the mobile nature of tourism employees; the lack of centralized funding; fear of the 'image problem' associated with HIV; and the lack of multisectoral policy dialogue and collaboration. Nevertheless, prior short-term experiences and changing attitudes among some private sector tourism representatives suggest emerging opportunities for policy change. We argue that the time is ripe for dialogue across the public-private divide in order to develop regulatory mechanisms, joint responsibilities and centralized funding sources to ensure a sustainable response to the HIV-tourism linkage. Policy priorities should focus on incorporating HIV prevention as a component of occupational health; reinforcing workers' health care rights as guaranteed by existing law; using private sector tourism representatives who support HIV prevention as positive role models for national campaigns; and

R and D Policies, Carbon Tax and Green Paradox

We study an economy in which a final good is produced by two sectors. One uses a non-renewable and polluting resource, the other a renewable and clean resource. A specific type of research is associated with each sector. The public authorities levy a carbon tax and simultaneously subsidise both research sectors. We study the impact of such a policy scheme on the rate of resource extraction and emissions. In the clean sector, the research subsidy and the carbon tax have opposite effects. If the tax creates a green paradox, the subsidy moderates it; if the tax slows resource extraction, then the subsidy generates a green paradox

Full Text Available Objective: To investigate the antibacterial effects of water and ethanolic extracts of henna leaves and roselle calyxes against pathogenic bacteria isolated from domestic wastewater. Methods: The antimicrobial activity was determined in the extracts using agar disc diffusion method. The antibacterial activities of extracts (2.5%, 5.0% and 10.0% w/v of both henna and roselle were tested against one Gram-positive Bacillius subtilis; two Gram-negative Escherichia coli, Pseudomonas aeruginosa human pathogenic bacteria. Results: Ethanolic extracts had more antimicrobial activity than water extracts. Ethanolic extract of roselle had the highest antibacterial activity against all tested organisms, followed with ethanolic extract of henna. Pseudomonas aeruginosa was the most sensitive bacteria to plant extracts. Conclusion: The results of this study suggested that roselle contains more phyto-chemicals with antimicrobial activity than henna on the bacteria strains under study, and these phyto-chemicals were more effective when extracted by ethanol rather than water.

It has been estimated that an RF cavity Beam Position Monitor (BPM) could provide a position measurement resolution of less than 1 nm. We have developed a high resolution cavity BPM and associated electronics. A triplet comprised of these BPMs was installed in the extraction line of the Accelerator Test Facility (ATF) at the High Energy Accelerator Research Organization (KEK) for testing with its ultra-low emittance beam. The three BPMs were each rigidly mounted inside an alignment frame on six variable-length struts which could be used to move the BPMs in position and angle. We have developed novel methods for extracting the position and tilt information from the BPM signals including a robust calibration algorithm which is immune to beam jitter. To date, we have demonstrated a position resolution of 15.6 nm and a tilt resolution of 2.1 μrad over a dynamic range of approximately ±20 μm.

A FRAMEWORK ANALYSIS OF EUROPEAN LABOUR MARKET POLICIES

Full Text Available The purpose of the paper is to analyse European labour market policies and their integrated guidelines, by highlighting various measures that need to be adopted in order to increase labour productivity, with positive effects on long-term economic development. The paper methodizes the main conditions complied by structural reforms in order to encourage labour employment and the policies that frame a more efficient unemployment insurance system crucial to increase security while encouraging the unemployed to look for a job and to accept a job offer, respectively on flexicurity policies. We found that employment rates are generally associated with large expenses on labour market policies and with an increased number of participants to programs developed within these types of policies. The degree of influence and strong dependence between outcome and labour market policies are illustrated in various ways and discussed within the paper.

Electronic nicotine delivery systems: executive summary of a policy position paper from the American College of Physicians.

Crowley, Ryan A

2015-04-21

Electronic nicotine delivery systems (ENDS), which include electronic cigarettes, or e-cigarettes, are growing in popularity, but their safety and efficacy as a smoking cessation aid are not well understood. Some argue that they have the potential to reduce tobacco-related morbidity and mortality and could be a useful tool for reducing tobacco-related harm. Others express concern that the health effects of ENDS use are unknown, that they may appeal to young people, and that they may encourage dual use of ENDS and traditional tobacco products. Although ENDS are a new and unregulated product, the U.S. Food and Drug Administration has proposed regulations that would deem ENDS to be subject to the Family Smoking Prevention and Tobacco Control Act, which regulates cigarettes and other tobacco products. In this position paper, the American College of Physicians offers policy recommendations on ENDS regulation and oversight, taxation, flavorings, promotion and marketing, indoor and public use, and research. This paper is not intended to offer clinical guidance or serve as an exhaustive literature review of existing ENDS-related evidence but to help direct the College, policymakers, and regulators on how to address these products.

When Environmental Policy is Superfluous: Growth and Polluting Resources

International Nuclear Information System (INIS)

Schou, Poul

2002-01-01

In a research-driven endogenous growth model, a non-renewable resource gives rise to pollution. Consumption may either grow or decline along the optimal balanced growth path, hut the (flow) pollution level necessarily diminishes continuously. Any positive balanced growth path is sustainable. Utility may improve, even though consumption declines. Although positive growth is optimal, the market economy may nevertheless result in permanently declining consumption possibilities. At the same time, a growth-enhancing government policy may improve long-run environmental conditions. The pollution externality does not distort the decisions of the market economy, so that a specific environmental policy is superfluous

Impacts of public policies and farmer preferences on agroforestry practices in Kerala, India.

Guillerme, S; Kumar, B M; Menon, A; Hinnewinkel, C; Maire, E; Santhoshkumar, A V

2011-08-01

Agroforestry systems are fundamental features of the rural landscape of the Indian state of Kerala. Yet these mixed species systems are increasingly being replaced by monocultures. This paper explores how public policies on land tenure, agriculture, forestry and tree growing on private lands have interacted with farmer preferences in shaping land use dynamics and agroforestry practices. It argues that not only is there no specific policy for agroforestry in Kerala, but also that the existing sectoral policies of land tenure, agriculture, and forestry contributed to promoting plantation crops, even among marginal farmers. Forest policies, which impose restrictions on timber extraction from farmers' fields under the garb of protecting natural forests, have often acted as a disincentive to maintaining tree-based mixed production systems on farmlands. The paper argues that public policies interact with farmers' preferences in determining land use practices.

Lack of physical activity is one of the greatest challenges of the 21st century. The Physical Activity Policy Research Network (PAPRN) is a thematic network established in 2004 to identify determinants, implementation, and outcomes of policies that are effective in increasing physical activity. The purpose of this study is to describe the products of PAPRN and make recommendations for future research and best practices. A mixed methods approach was used to obtain both quantitative and qualitative data on the network. First, in 2014, PAPRN's dissemination products from 2004 to 2014 were extracted and reviewed, including 57 publications and 56 presentations. Next, semi-structured qualitative interviews were conducted with 25 key network participants from 17 locations around the U.S. The transcripts were transcribed and coded. The results of the interviews indicated that the research network addressed several components of its mission, including the identification of physical activity policies, determinants of these policies, and the process of policy implementation. However, research focusing on physical activity policy outcomes was limited. Best practices included collaboration between researchers and practitioners and involvement of practitioners in research design, data collection, and dissemination of results. PAPRN is an example of a productive research network and has contributed to both the process and content of physical activity policy research over the past decade. Future research should emphasize physical activity policy outcomes. Additionally, increased partnerships with practitioners for collaborative, cross-sectoral physical activity policy research should be developed.

Social values and solar energy policy: the policy maker and the advocate

Energy Technology Data Exchange (ETDEWEB)

Shama, A.; Jacobs, K.

1980-07-01

Solar energy policy makers and advocates have significantly different hierarchies (clusters) of values upon which they evaluate the adoption of solar technologies. Content analysis, which examines the frequency with which policy makers identify different types of values, indicates that they hold economic values to be of primary importance. Environmental, social, and national security values are also substantial elements of the policy makers' value clusters associated with solar energy. This finding is confirmed by a qualitative analysis of policy makers' values. Advocates, on the other hand, assign almost equal weights (33%) to economic values and social values, slightly less weight to environmental values, and significant attention to ethical and security values as well. These results of frequency analysis are made somewhat more complicated by a qualitative interpretation of the advocates' positions. As part of their more holistic approach, several of the advocates indicated that all values discussed by them are instrumental toward achieving higher-order, ethical and environmental values. In addition, our preliminary investigation indicates that neither group is entirely homogeneous. Testing this and other propositions, as well as obtaining a similar picture of the values which the public associates with solar energy, are topics of future research.

2018-03-01

Antibacterial drugs derived from natural sources play significant roles in the prevention and treatment of bacterial infections since antibiotics have become less effective against many infectious diseases. Mangroves are very potential natural antibacterial sources among great numbers of wild medicinal plants. Bruguiera cylindrica is one of the many mangroves species which spread along Indonesian coastline. The aim of this study was to explore the antibacterial activity of B. cylindrica wet and dried leaf extracts. The wet extracts study was conducted with three different solvents system (water, ethanol, and n-Hexane) against Escherichia coli and Staphylococcus aureus. While, the dried extracts study was conducted with four different solvents system (water, ethanol, chloroform and n-Hexane) against three types of bacteria, Escherichia coli, Staphylococcus epidermidis and Staphylococcus aureus. The study showed that ethanol was the best solvent for extraction of phenolic and flavonoid. Antibacterial actitivity was measured by zone of inhibition which obtained from agar-disk diffusion method. The widest area of zone of inhibition was showed by wet extracts with ethanol against S. aureus and E. coli are 14.30 and 13.30 mm, respectively. While, the zone of inhibition dried extracts with ethanol against S. aureus, S. epidermidis and E. coli are 9.32, 6.59 and 6.20 mm, respectively. In conclusion, both type of extracts showed significant antibacterial activity against gram-positive bacteria as crude extracts.

Underdeveloping Appalachia: Toward an environmental sociology of extractive economies

Science.gov (United States)

Wishart, William Ryan

This dissertation uses mixed methods to examine the role of the coal industry in the reproduction of Central Appalachia as an internal periphery within the United States and the economic, ecological, and human inequalities this entails. It also analyzes the related political economy and power structure of coal in a national context. Particularly important for analysis of the region's underdevelopment are the class relations involved in unequal ecological exchange and the establishment of successive "modes of extraction." I employ a historical comparative analysis of Appalachia to evaluate Bunker's thesis that resource dependent peripheries often become locked into a "mode of extraction" (with aspects parallel to Marxist concepts of mode of production) triggering economic and ecological path dependencies leading to underdevelopment. This historical comparative analysis establishes the background for a closer examination of the political economy of the modern US coal industry. After sketching the changes in the structure of monopoly and competition in the coal industry I employ network analysis of the directorate interlocks of the top twenty coal firms in the US within the larger energy policy-planning network to examine their connections with key institutions of the policy formation network of think tanks and business groups. My findings show the importance of the capacities of fossil fuel fractions of the capitalist class in formulating energy policy around issues such as the 2009 climate legislation. As a contribution to the growing literature applying the concept of metabolism as link between contemporary and classical theory, I examine the conflict at Coal River Mountain from the vantage points of ecology, political economy, and human development in dialectical rotation. Utilizing Marx's method of successive abstractions, the mountain is presented as a nexus of metabolic rifts in the human relationship to the earth's natural systems and an impediment to genuine

In this work, the in vitro antimicrobial activity of different crude extracts obtained from Cistus ladanifer L. and Arbutus unedo L. was investigated. The ethanol, methanol and acetone/water extracts of Cistus ladanifer and Arbutus unedo were prepared using different extraction methods and their antimicrobial activities against reference strains, including three Gram-positive, five Gram-negative and three yeasts, and against clinical isolates of Helicobacter pylori and methicillin-resistant Staphylococcus aureus, were investigated. All the extracts inhibited more than one microorganism; moreover all of them presented antimicrobial activity against the Gram-positive bacteria, Klebsiella pneumonia, Candida tropicalis and Helicobacter pylori. It is noteworthy that the most considerable in vitro effect was observed against Helicobacter pylori. These inhibitory effects can be considered relevant to the development of new agents for inclusion in the treatment or prevention of infections by the tested strains.

Antibiotic therapy in hospitals has substantial impact on patient outcome and the pharmacy drug budget. Antibiotic policies have been implemented by some hospitals to improve the quality of patient outcome and cost of antibiotic therapy. Antibiotic policies impose certain requirements on pharmacists and physicians. Pharmacists' and physicians' attitudes to and opinions about antibiotic policies are likely to affect the usefulness of such policies. To determine the attitudes of pharmacists and physicians to antibiotic policies in New South Wales (NSW) hospitals. Pharmacists and physicians in NSW public hospitals were surveyed to determine their attitudes to and opinions on antibiotic policies. A simple one-stage cluster sample of 241 pharmacists and a two-stage cluster sample of 701 physicians were obtained. Factor analysis was used to identify the attitudinal dimensions. General linear modelling was used to investigate the effects of predictor variables on outcome variables. The response rates were 91% and 77% for pharmacists and physicians, respectively. Factor analysis identified three dimensions of attitude to antibiotic policies: that they encourage rational antibiotic use; that they improve the quality of antibiotic prescribing and that they are associated with some problems. The reliability of these factors (Cronbach's alpha) ranged from 0.71 to 0.74, and was 0.90 for the overall attitude scale. Pharmacists and physicians had a positive overall attitude to antibiotic policies. Whereas physicians recognize that antibiotic policies improve the quality of prescribing, this was highly correlated with identification of problems (alpha = 0.71). In urban hospitals, pharmacists were more likely than physicians to associate antibiotics with problems. There was a positive overall attitude to hospital antibiotic policies expressed by pharmacists and physicians.

Mental health policy can be an essential and powerful tool to improve a population's mental health. However, around one third of countries do not possess a mental health policy, and there are large disparities in population coverage rates between high- and low-income countries. The goal of this study is to identify the transition and implementation challenges of mental health policies in both high-income countries (HICs) as well as middle- and low-income countries (MLICs). PubMed, Cochrane Library and Campbell Library were searched from inception to 31 December 2017, for studies on implemented mental health policies at the national level. Abstracts and the main texts of papers were double screened, and extracted data were analysed through thematic synthesis. A total of 93 papers were included in this study, covering 24 HICs, 28 MLICs and 5 regions. Studies on mental health policies, especially those of MLICs, kept increasing, but MLICs were still underrepresented in terms of publication quantity and study frequency. Based on the included studies, nine policy domains were summarized: service organizing, service provision, service quality, human resources, legislation and human rights, advocacy, administration, surveillance and research, and financing and budgeting. HICs incrementally enriched their policy content in all domains over centuries of development; following HICs' experience, mental health policies in MLICs have boomed since the 1990s and quickly extended to all domains. Implementation problems in HICs were mainly related to service organizing and service provision; for MLICs, more severe implementation problems converged on financing and budgeting, administration and human resources. Mental health policy developments in both HICs and MLICs present a process of diversification and enrichment. In terms of implementation, MLICs are faced with more and greater challenges than HICs, especially in funding, human resources and administration. Therefore, future

Various biophysical and socio-economic impacts may be associated with unconventional oil and gas (UOG) extraction. A vulnerability map may assist governments during environmental assessments, spatial planning and the regulation of UOG extraction, as well as decision-making around UOG extraction in fragile areas. A regional interactive vulnerability map was developed for UOG extraction in South Africa. This map covers groundwater, surface water, vegetation, socio-economics and seismicity as mapping themes, based on impacts that may emanate from UOG extraction. The mapping themes were developed using a normative approach, where expert input during the identification and classification of vulnerability indicators may increase the acceptability of the resultant map. This article describes the development of the interactive vulnerability map for South Africa, where UOG extraction is not yet allowed and where regulations are still being developed to manage this activity. The importance and policy implications of using vulnerability maps for managing UOG extraction impacts in countries where UOG extraction is planned are highlighted in this article.

Do driving restriction policies effectively motivate commuters to use public transportation?

Liu, Yunxia; Hong, Zaisheng; Liu, Yong

2016-01-01

Driving restriction policies have been implemented in some large Chinese cities to cope with severe urban smog pollution. We explored the roles of policy acceptance and other factors in commuters' transport mode decisions, based on the Theory of Planned Behavior. A questionnaire survey was conducted in Tianjin, China. A structural equation model was developed to test eight hypotheses, two of which were rejected. The results indicate that a driving restriction policy alone cannot effectively motivate commuters to use public transport if the policymakers fail to improve public transport, enhance commuters' awareness of consequences, increase commuters' perceived behavior control, and encourage car owners to change driving behavior. Comparisons between car owners and non-owners indicated that car owners view driving restriction policy and public transport more negatively. These negative views could be a barrier for the promotion of public transport among car owners. In addition, attitude toward public transport was found to have positive correlation with commuting time. - Highlights: • Attitude towards public transport has an impact on policy acceptance. • Driving habit indirectly affects policy acceptance and perceived behavior control. • Driving restriction policy and public transport are not popular among car owners. • Attitude towards public transport correlates positively with commuting time.

Woody biomass: Niche position as a source of sustainable renewable chemicals and energy and kinetics of hot-water extraction/hydrolysis.

Science.gov (United States)

Liu, Shijie

2010-01-01

The conversion of biomass to chemicals and energy is imperative to sustaining our way of life as known to us today. Fossil chemical and energy sources are traditionally regarded as wastes from a distant past. Petroleum, natural gas, and coal are not being regenerated in a sustainable manner. However, biomass sources such as algae, grasses, bushes and forests are continuously being replenished. Woody biomass represents the most abundant and available biomass source. Woody biomass is a reliably sustainable source of chemicals and energy that could be replenished at a rate consistent with our needs. The biorefinery is a concept describing the collection of processes used to convert biomass to chemicals and energy. Woody biomass presents more challenges than cereal grains for conversion to platform chemicals due to its stereochemical structures. Woody biomass can be thought of as comprised of at least four components: extractives, hemicellulose, lignin and cellulose. Each of these four components has a different degree of resistance to chemical, thermal and biological degradation. The biorefinery concept proposed at ESF (State University of New York - College of Environmental Science and Forestry) aims at incremental sequential deconstruction, fractionation/conversion of woody biomass to achieve efficient separation of major components. The emphasis of this work is on the kinetics of hot-water extraction, filling the gap in the fundamental understanding, linking engineering developments, and completing the first step in the biorefinery processes. This first step removes extractives and hemicellulose fractions from woody biomass. While extractives and hemicellulose are largely removed in the extraction liquor, cellulose and lignin largely remain in the residual woody structure. Xylo-oligomers and acetic acid in the extract are the major components having the greatest potential value for development. Extraction/hydrolysis involves at least 16 general reactions that could

Full Text Available The main objective of this paper is trying to measure the effectiveness of selected supply side and demand side policies on Thai economy by using Computable General Equilibrium (CGE model. We found that there is a special characteristic of the unskilled labor movement among agricultural sector and other sectors in Thailand and this characteristic can represented by Harris-Todaro expected wage equation. Therefore, we developed the CGE model incorporating Harris-Todaro expected wage equilibrium for the labor market. The simulation result shows that, for selected supply side policy, the reduction of switching cost, increasing labor productivity (which are selected supply side policy, increasing in government spending and export promotion (which are selected demand side policy can contribute positive impacts to Thai economy. Interestingly, we found that if both the reduction of switching cost and the increasing labor productivity are implemented together, they will generate even more positive impacts to Thai economy than separately implemented. This finding suggests policy maker should implement both the reduction of switching cost and the increasing labor productivity together in order to gain more benefit to Thai economy. These two policies are supply side policy and related to labor market, thus improving labor market is a great choice for Thailand. Lastly, we found that all policies have the similar non-linear characteristic.

An integrated questionnaire for these interviews will collect both quantitative data through Likert scale-type questions, and qualitative data through open-ended questions. And finally focused dialogues will be conducted with selected stakeholders for feedback on the PIB findings. Secondary data will be collected using data extraction tools for performance statistics. It is anticipated that the PIB findings and more importantly, the focused dialogues with relevant stakeholders, that will be convened to discuss the findings and establish corrective actions, will enhance uptake of results and effective health policy implementation towards universal health coverage in Uganda.

Consumer support for pro environmental food policies and food purchasing are important for the adoption of successful environmental policies. This paper examines consumers' views of food policy options as their predisposition to purchase pro environmental foods along with their likely demographic, educational and cognitive antecedents including food and environmental concerns and universalism values (relating to care for others and the environment). An online survey to assess these constructs was conducted among 2204 Australian adults in November 2011. The findings showed strong levels of support for both environmental food policies (50%-78% support) and pro environmental food purchasing (51%-69% intending to purchase pro environmental foods). Confirmatory factor analysis and structural equation modelling showed that different cognitive mediators exist along pathways between demographics and the two outcome variables. Support for food policy was positively related to food and environment concerns (std. Beta = 0.25), universalism (0.41), perceived control (0.07), and regulatory issues (0.64 but negatively with food security issues (-0.37). Environment purchasing intentions were positively linked to food and nutrition concerns (0.13), food and environment concerns (0.24), food safety concerns (0.19), food and animal welfare concerns (0.16), universalism (0.25), female gender (0.05), education (0.04), and perceived influence over the food system (0.17). In addition, health study in years 11 and 12 was positively related to the beginning of both of these pathways (0.07 for each). The results are discussed in relation to the opportunities that communications based on the mediating variables offer for the promotion of environmental food policies and purchasing.

2015-04-01

Full Text Available Introduction: Today, medicinal plants are being widely used due to being natural, available, and cheaper than synthetic drugs and having minimum side effects. Since there were reports about the antibacterial properties of Solanum tuberosum (SE, the aim of this study was to investigate the antibacterial effects of SE ethanol extract in vitro condition on Streptococcus pyogenes, Staphylococcus aureus, Pseudomonas aeruginosa and Klebsiella pneumoniae. Methods: Ethanol extract of SE peel was prepared by maceration method. Initially, antibacterial activity of ethanol extract of SE was qualitatively determined by disk diffusion test; then, the minimum inhibitory concentration and minimum bactericidal concentration were qualitatively determined by micro-dilution method. Results: SE peel extract had antibacterial properties and its effect was more pronounced on gram-positive bacteria, especially S. aureus (0.62±0.00 mg/ml. The extract had antibacterial activity on gram-negative bacteria, P. aeruginosa, too (8.33±2.88 mg/ml. Conclusion: SE peel extract has antibacterial activity and its effect on gram-positive bacteria was more pronounced than the investigated gram-negative bacteria. Therefore, it is suggested that SE peel constituent compounds be determined and to determine the exact mechanism of its antibacterial properties, and more comprehensive research be done to apply it, clinically.

National policy on radioactive waste management

Jova, Luis; Metcalfa, Phil; Rowata, John; Louvata, Didier; Linsley, Gordon

2008-01-01

Every country should have some form of policy and strategy for managing its spent fuel and radioactive waste. Such policies and strategies are important; they set out the nationally agreed position and plans for managing spent fuel and radioactive waste and are visible evidence of the concern and intent of the government and the relevant national organisations to ensure that spent fuel and radioactive waste are properly taken care of in the country. There is a large diversity in the types and amounts of radioactive waste in the countries of the world and, as a result of this diversity, the strategies for implementing the policies may be different, although the main elements of policy are likely to be similar from country to country. In some countries, the national policy and strategy is well established and documented, while in others there is no explicit policy and strategy statement and, instead, it has to be inferred from the contents of the laws, regulations and guidelines. The present paper describes the work undertaken by the International Atomic Energy Agency (IAEA) related to identifying the main elements of national policies for spent fuel and radioactive waste management, recognising that policies and strategies vary considerably depending on, among other things, the nature and scale of applications of radioactive material in a country. An indication is provided of what might be contained in national policies recognizing that national policy and strategy has to be decided at the national level taking into account national priorities and circumstances. The paper is concerned with the contents of policies and strategies and does not address the development of national laws, regulations and guidelines - although these are clearly related to the contents of the national policy and strategy.

Streimikiene, Dalia; Sivickas, Gintautas

2008-11-01

The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.

Iran`s petroleum policy: Current trends and the future outlook

Energy Technology Data Exchange (ETDEWEB)

Pezeshki, S.; Fesharaki, F.

1994-12-01

The Iranian economy and political situation have undergone radical changes since the 1979 Islamic revolution. The excesses of the early years of the revolution have gradually given way to moderation and a more pragmatic economic policy--based on the principles of the free market. The petroleum policy, as a subset of the economic policies, has been somewhat affected by the political and economic developments in Iran. The petroleum policy has changed from a position of no foreign participation to a position that includes a desire for foreign participation, the text of a model contract, and an attempt to introduce new technologies in the upstream sector. This report provides an overview of the key issues facing the Iranian oil industry and the economic context in which the oil industry is operating in Iran. It describes the evolution of policies meant to move the oil industry toward the free market; it discusses Iran`s oil trading partners, the outlook for refining and project investments, and current and likely future developments in the natural gas and petrochemical sectors. In short, the report provides an up-to-date assessment of the Iranian petroleum sector and its likely evolution in the future.

Renewable fuels: Policy effectiveness and project risk

Leach, Andrew; Doucet, Joseph; Nickel, Trevor

2011-01-01

This paper examines the impact of government policy on the risk profile of a small ethanol production facility. We derive four key results from a simulation model. First, we show that commodity price risk may discourage investment in a project, despite a positive expected rate of return. Second, we show that political uncertainty may have significant impacts on the risk profile of a project. Next, we show that using only production subsidies to attract investors is expensive, since the financial assistance is paid regardless of whether the plant is operating under positive or negative financial conditions. Finally, we show that a capital grant provides a valuable complement to a subsidy, because the grant reduces the amount of value investors must put at risk, and increases their leverage thereby enhancing returns, while the subsidy mitigates commodity price risk. Our results show that compared to a subsidy-only approach, a grant and subsidy combination provides an investment environment with similar downside protection and expected returns for less than 60% of the cost. Further, we show that the two policy tools combined yield a superior investment environment to that created by an equivalent or greater total investment deployed entirely in either of the policy tools without the other. - Research highlights: → We find that government policy may increase both project returns and risk. → We find a policy of capital grants combined with an output price support to be preferred. → Price supports alone will tend to reward those plants which need them the least.

The evidence-policy divide: a 'critical computational linguistics' approach to the language of 18 health agency CEOs from 9 countries.

Bell, Erica; Seidel, Bastian M

2012-10-30

There is an emerging body of literature suggesting that the evidence-practice divide in health policy is complex and multi-factorial but less is known about the processes by which health policy-makers use evidence and their views about the specific features of useful evidence. This study aimed to contribute to understandings of how the most influential health policy-makers view useful evidence, in ways that help explore and question how the evidence-policy divide is understood and what research might be supported to help overcome this divide. A purposeful sample of 18 national and state health agency CEOs from 9 countries was obtained. Participants were interviewed using open-ended questions that asked them to define specific features of useful evidence. The analysis involved two main approaches 1)quantitative mapping of interview transcripts using Bayesian-based computational linguistics software 2)qualitative critical discourse analysis to explore the nuances of language extracts so identified. The decision-making, conclusions-oriented world of policy-making is constructed separately, but not exclusively, by policy-makers from the world of research. Research is not so much devalued by them as described as too technical- yet at the same time not methodologically complex enough to engage with localised policy-making contexts. It is not that policy-makers are negative about academics or universities, it is that they struggle to find complexity-oriented methodologies for understanding their stakeholder communities and improving systems. They did not describe themselves as having a more positive role in solving this challenge than academics. These interviews do not support simplistic definitions of policy-makers and researchers as coming from two irreconcilable worlds. They suggest that qualitative and quantitative research is valued by policy-makers but that to be policy-relevant health research may need to focus on building complexity-oriented research methods for

Pharmaceutical policies in European countries.

Science.gov (United States)

Barros, Pedro Pita

2010-01-01

Pharmaceutical expenditures have an important role in Europe. The attempts to control expenditure have used a wide range of policy measures. We reviewed the main measures adopted by the European Union countries, especially in countries where governments are the largest third-party payers. To complement a literature review on the topic, data was gathered from national reviews of health systems and direct inquiries to several government bodies. Almost all countries regulate prices of pharmaceutical products. Popular policy measures include international referencing to set prices (using as benchmark countries that have set lower prices), internal reference pricing systems to promote price competition in domestic markets, and positive lists for reimbursement to promote consumption of generics (including in some cases substitution by pharmacists of drugs prescribed by physicians). Despite the wide range of policy measures, it is not possible to identify a "silver bullet" to control pharmaceutical expenditures. We also identified two main policy challenges: policy coordination among countries within the European Union to maintain incentives for R&D at the global level, and the development of new relationships with the pharmaceutical industry; namely, the so-called risk-sharing agreements between the pharmaceutical industry and governments/regulators (or large third-party payers).

Integrated environmental policy: A review of economic analysis.

Science.gov (United States)

Wiesmeth, Hans; Häckl, Dennis

2017-04-01

Holistic environmental policies, which emerged from a mere combination of technical activities in waste management some 40 years ago, constitute the most advanced level of environmental policies. These approaches to environmental policy, among them the policies in integrated waste management, attempt to guide economic agents to an environment-friendly behaviour. Nevertheless, current holistic policies in waste management, including policies on one-way drinks containers and waste electrical and electronic equipment, and implementations of extended producer responsibility with further applications to waste electrical and electronic equipment, reveal more or less severe deficiencies - despite some positive examples. This article relates these policy failures, which are not necessarily the result of an insufficient compliance with the regulations, to missing constitutive elements of what is going to be called an 'integrated environmental policy'. This article therefore investigates - mostly from a practical point of view - constitutive elements, which are necessary for a holistic policy to serve as a well-functioning allocation mechanism. As these constitutive elements result from a careful 'integration' of the environmental commodities into the economic allocation problems, we refer to these policies as 'integrated environmental policies'. The article also discusses and illustrates the main steps of designing such a policy - for waste electrical and electronic equipment and a (possible) ban of Glyphosat in agriculture. As these policies are dependent on economic and political stability with environmental awareness sufficiently developed, the article addresses mostly waste management policies in highly industrialised countries.

Ultrasonic instruments can be used to determine many of the parameters of interest in a liquid/liquid extraction plant, eg liquid levels, the position of interfaces between immiscible liquids and the concentration of solutions. The determinations can often be made non-invasively. A number of instruments developed for a liquid/liquid extraction plant used for nuclear fuel reprocessing is described. These instruments have a wider application in liquid/liquid extraction plant in general. (author)

Antimicrobial potential of leaf and fruit extracts and oils of wild and cultivated edible olive

International Nuclear Information System (INIS)

Hussain, A.; Qurshi, I.A.; Liaqat, R.; Akhtar, S.; Aziz, I.

2014-01-01

Olive tree is the first botanical noted in the Bible. Leaves and fruits of olive are rich sources of Phenols, triterpenes, and flavanoids. Oleuropein obtained from the leaves extract is believed to be important therapeutic compound. Olive leaf and oils are used for the treatment of different diseases as folklore medicines by different ethnic groups in different countries of the world. The present study aims to investigate the potential antimicrobial activities of wild (Olea ferruginea) and edible (Olea europaea) olive leaf crude extracts, crude oils from ripe and unripe fruits and extra virgin oils against the selected gram positive and gram negative bacterial strains. The results show that olive leaf and oil have potential antibacterial activities against some of the gram positive and gram negative bacterial strains. However, certain strains were resistant to the extracts. It was also found that the activities were higher for the gram negative strains as compared to gram positive strains. The methanolic and ethanolic extracts were found to be more efficient in extraction than the other solvents used. Leaf extracts were more effective than the oil extracted from ripe and unripe fruits. There was no significant difference in the activities of extra virgin oils and crude leaf extracts. From the results it is concluded that the leaf extract is a cheap and effective antibacterial agent that can be used as alternative to purified oil. (author)

Greening of Nordic electricity industry: policy convergence and diversity

Midttun, Atle; Gundersen, Mari Hegg; Koefoed, Anne Louise

2004-01-01

With a comparative focus on policy similarity and diversity, this article gives an overview of the main elements of electricity-related environmental policy in the Nordic countries, following the launching of a common electricity market in the 1990s. The article points out that the electricity related environmental policy positions of the Nordic countries showed a noticeable lack of coordination in the 1990s. Nordic divergence is observed both in terms of general policy orientations and at the instrument and incentive levels, in spite of the pioneering development of a common integrated electricity market and ambitious environmental policy goals. The article then highlights how the recent Swedish 'green' certificate market model has created a new momentum for market-based 'greening' with a potential for stronger convergence in Nordic renewable energy policy. In spite of signs of convergence, the article shows how the development of Nordic electricity-related environmental policy still contains considerable ambiguity: Unequal resource endowments, subject to simple resource-based interest formation, should indicate that there is little room for convergence in Nordic renewable energy policy. Shifting the environmental policy focus from existing technologies and resources to potential innovations, however provides a more open arena where the Nordic countries may see themselves served by the dynamic scope of a broader Nordic market based on a common policy approach, such as a green certificate market. In explaining why the Nordic arena may be an interesting locus for common renewable energy policy, the article points out that small countries may need an 'intermediary' arena to aggregate size and scope in order to generate a European momentum in regulatory competition with larger European states. Similarly, Nordic companies may consider the opportunity to gain first mover advantages by partnering with government as local experimentation may be seen as useful pilot

Renewable Energy Innovation Policy. Success Criteria and Strategies

Energy Technology Data Exchange (ETDEWEB)

NONE

2013-03-15

Renewable energy technology (RET) innovation involves new, improved processes, as well as strategies to accelerate RET development, ranging from breakthroughs with basic technology inventions and improved research, development and deployment (RDD) systems, to improved market mechanisms and commercialisation. In order to achieve RET innovation, a country needs to put in place the right policy approaches, frameworks, governance and policy instruments. This working paper was compiled to assist countries with policy development in order to strengthen renewable energy innovation, primarily through a discussion of design criteria for innovation policy frameworks. The report identifies broad success criteria for innovation policy in the sector and suggests strategic policy approaches to advance RET innovation in the context of constrained options, competition for resources, and national economic development goals. For renewable energy innovation policy regimes to be succeed, they must satisfy two broad criteria: (a) promotion of sustained multi-stakeholder engagement around an achievable, shared vision; and (b) appropriate positioning of a country or region to anticipate and benefit from renewable energy technology flows.

As in the rest of the world, the India's foreign policy was marked by the dynamics of continuity and change in world policy, associated with the historical period of the Cold War (1947-90) and its impact on the neighbouring and regional context of India. As its hypothesis this article argues that this period was characterized by the challenges of consolidating the autonomy of independence, which means: achieving development; solving disputes arising from conflicts with neighbours; and, presenting India as a country committed to peace, which explains not only its position against war and the use of nuclear weapons, but also, with respect to one of the most original aspects of Indian foreign policy, its status as a non-aligned country

2004-10-31

Working within the context of the Southern States Biobased Alliance (SSBA) and with officials in each state, the Southern States Energy Board (SSEB) is identifying bioenergy-related policies and programs within each state to determine their impact on the development, deployment or use of bioenergy. In addition, SSEB will determine which policies have impacted industry's efforts to develop, deploy or use biobased technologies or products. As a result, SSEB will work with the Southern States Biobased Alliance to determine how policy changes might address any negative impacts or enhance positive impacts. In addition to analysis of domestic policies and programs, this project will include the development of a U.S.-Brazil Biodiesel Pilot Project. The purpose of this effort is to promote and facilitate the commercialization of biodiesel and bioenergy production and demand in Brazil.

Public policy is generally believed to have an effect on the emergence and rate of diffusion of technology. Solar energy technologies are no exception. This article explores the relationship between a variety of United States (US) public policies and the emergence and diffusion of solar energy technologies using data gathered as part of the National Solar Energy Policy Study. The article presents findings regarding the status and policy position of US renewable energy research and development (R and D) and manufacturing organizations. Specific policy options which could be adopted to speed emergence and diffusion of solar energy technology products are discussed. (Author)

Stochastic abstract policies: generalizing knowledge to improve reinforcement learning.

Koga, Marcelo L; Freire, Valdinei; Costa, Anna H R

Reinforcement learning (RL) enables an agent to learn behavior by acquiring experience through trial-and-error interactions with a dynamic environment. However, knowledge is usually built from scratch and learning to behave may take a long time. Here, we improve the learning performance by leveraging prior knowledge; that is, the learner shows proper behavior from the beginning of a target task, using the knowledge from a set of known, previously solved, source tasks. In this paper, we argue that building stochastic abstract policies that generalize over past experiences is an effective way to provide such improvement and this generalization outperforms the current practice of using a library of policies. We achieve that contributing with a new algorithm, AbsProb-PI-multiple and a framework for transferring knowledge represented as a stochastic abstract policy in new RL tasks. Stochastic abstract policies offer an effective way to encode knowledge because the abstraction they provide not only generalizes solutions but also facilitates extracting the similarities among tasks. We perform experiments in a robotic navigation environment and analyze the agent's behavior throughout the learning process and also assess the transfer ratio for different amounts of source tasks. We compare our method with the transfer of a library of policies, and experiments show that the use of a generalized policy produces better results by more effectively guiding the agent when learning a target task.

Verbascum antiochium Boiss., a member of the Scrophulariaceae family, is endemic to Turkey. The extracts obtained from V. antiochium by increased polarity and direct methanol extraction were tested by the agar well diffusion method against various Gram-positive and Gram-negative bacteria and one fungus. The methanol/water extract exhibited a larger inhibition zone against both the Gram-negative and Gram-positive bacteria than the other extracts. Haemophilus influenzae was found to be the most sensitive bacterium among the bacteria tested. The antioxidant activities of the methanolic extract of V. antiochium were examined by two complementary test systems. The 50% inhibition activity of the methanolic extract of V. antiochium against the free radical 2,2-diphenyl-1-picrylhydrazyl was determined as 4.80 mg/mL. In the case of the linoleic acid system, oxidation of linoleic acid was inhibited by the methanolic extract of V. antiochium with 79.92% inhibition, which is close to the value of the synthetic antioxidant reagent, tert-butylated hydroxytoluene. The total phenolic components of V. antiochium were determined to be 92.71 mg of gallic acid equivalents/g. Iridoid glycosides, flavonoids, and saponins were detected as the major chemical constituents in the extract.

Full Text Available Introduction: The worldwide increased bacterial resistance to antibiotics and the undesirable side effects associated with constant use of synthetic drugs has prompted the search for novel antimicrobial agents, particularly those manufactured from plants. This study is designed to ascertain the antibacterial potential of Rhus succedanea leaf gall extracts on the growth of gram-positive and gram–negative bacteria. Methods: The methanolic and hexane extract of different concentrations (100, 250, and 500 μg/ml were prepared and their antibacterial efficacy was tested against clinical isolates of Escherichia coli, Salmonella typhi, Micrococcus luteus, and Staphylococcus aureus using agar well diffusion method and the size of inhibition zone was measured in millimeters. Results: The methanol and hexane extracts differed significantly in their antimicrobial activity with methanol extract showing a potent inhibitory activity in the range of 16±2 to 23±1, which was almost equal to the values of ciprofloxacin (25±3, used as a standard. Further, the methanol extract was mostly potent and effective in inhibiting the growth of gram-negative bacteria, namely, E. coli, when compared to gram –positive bacteria stains, which are responsible for antimicrobial activities. The phytochemical screening showed positive results for the presence of steroids, triterpenes, alkaloids, and carbohydrates. Conclusion: The potent antibacterial activity of Rhus succedanea leaf gall extracts indicates its useful therapeutic application against bacterial infection. Furthermore, this study indicates that the extract might be exploited as natural drug for the treatment of infectious diseases and could be useful in understanding the relations between traditional cures and current medications.

National policy measures. Right approach to foreign direct investment flows

2013-02-01

Full Text Available 2011 was a difficult year for all the countries, developed and emerging ones. For overcoming the negative effects of the financial crisis, many economies have established as purpose to adopt new economic policies regarding the foreign direct investment flows (FDI, even to stimulate the flows or to reduce it (protectionism measures. So, there can be identified two categories of national policies: measures for the FDI flows stimulation and measures whose aim was the weighting of FDI developing, through restriction and regulation. In the first category we could include the liberalization measures and promotional and faciletation policies. In this study we evidenced that the fundament of the second category of policies is the belief that the FDI outward lead to job exports, to a raise of unemployment and a weakness of the industrial base.Many reports on FDI flows, here we talk about those made by UNCTAD, show that the regulation and restriction policies are seen as a possible protectionism, especially in the agricultural and extractive industries, where there have been required nationalization processes and divestments. Even more, the economies which adopted this kind of policies have been less interested in investing abroad, the outward of FDI being affected and globally the total outward decreased.

2015-12-01

Full Text Available The paper investigates the extent to which Romania’s largest travel agencies adopt and implement corporate social responsibility (CSR policies, correlating these findings with their business performance reflected by their net turnover and net profit. In order to evaluate the level of CSR policies adoption and implementation, an online survey was conducted among top managers from each travel agency. The questionnaire comprised several sets of items reflecting workplace, environmental, marketplace, community, and, respectively, company values policies. Our results point to the fact that the CSR policies adopted and implemented to the highest degree are those concerning the marketplace, while the least embraced CSR policies refer to the environment. Our findings also suggest that there are several CSR policies which are adopted and implemented to a higher degree by larger travel agencies in terms of net turnover, while some other CSR policies are adopted more thoroughly by smaller ones. The results also indicate positive correlations between the profitability of travel agencies and the adoption and implementation of certain CSR policies. Last but not least, our research suggests that marketplace policies adoption and implementation could have a significant positive impact on business performance of travel agencies in terms of both net turnover and net profitability.

Metal ion extractant in microemulsions: where solvent extraction and surfactant science meet

International Nuclear Information System (INIS)

Bauer, C.

2011-01-01

The presented work describes the supramolecular structure of mixtures of a hydrophilic surfactant n-octyl-beta-glucoside (C8G1), and the hydrophobic metal ion extractant tributylphosphate (TBP) in n-dodecane/water as well as in the presence of salts. In the first part, basic solvent extraction system, composed of water, oil and extractant, will be introduced. The focus, however, lies on the extraction of multivalent metal ions from the aqueous phase. During this extraction process and in the following thermodynamic equilibrium, aggregation and phase transition in supramolecular assemblies occur, which are already described in literature. Notably, these reports rest on individual studies and specific conclusions, while a general concept is still missing. We therefore suggest the use of generalized phase diagrams to present the physico-chemical behaviour of (amphiphilic) extractant systems. These phase diagrams facilitated the development of a thermodynamic model based on molecular geometry and packing of the extractant molecules in the oil phase. As a result, we are now in the position to predict size and water content of extractant aggregates and, thus, verify the experimental results by calculation.Consequently, the second part presents a systematic study of the aqueous and organic phase of water/C8G1 and water/oil/TBP mixtures. The focus lies on understanding the interaction between metal ions and both amphiphilic molecules by means of small angle x-ray scattering (SAXS), dynamic light scattering (DLS) and UV-Vis spectroscopy. We confirmed the assumption that extraction of metal ions is driven by TBP, while C8G1 remains passive. In the third and last part, microemulsions of C8G1, TBP, water (and salt) and n-dodecane are characterized by small angle neutron scattering (SANS), and chemical analytics (Karl Fischer, total organic carbon, ICP-OES,...). The co-surfactant behaviour of TBP was highlighted by comparison to the classical n-alcohol (4≤n≤8) co

Full Text Available Sensitivity of the molecular diagnostic tests of extrapulmonary tuberculosis largely depends upon the efficiency of DNA extraction methods. The objective of our study was to compare three methods of extracting DNA of Mycobacterium tuberculosis for testing by polymerase chain reaction. All three methods; heating, heating with sonication and addition of lysis buffer with heating and sonication were implicated on 20 extrapulmonary samples. PCR positivity was 2 (10%, 4 (20% and 7 (35% in the samples extracted by heating, heat+sonication and heat+sonication+lysis buffer method respectively. Of the extraction methods evaluated, maximum PCR positive results were achieved by combined heat, sonication and lysis buffer method which can be applied in routine clinical practice. Ibrahim Med.

Drilling through Conservation Policy: Oil Exploration in Murchison Falls Protected Area, Uganda

Full Text Available Approximately 2.5 billion barrels of commercially-viable oil, worth $2 billion in annual revenue for 20 years, were discovered under the Ugandan portion of the Albertine Rift in 2006. The region also contains seven of Uganda's protected areas and a growing ecotourism industry. We conducted interviews and focus groups in and around Murchison Falls Protected Area, Uganda's largest, oldest, and most visited protected area, to assess the interaction of oil exploration with the three primary conservation policies employed by Uganda Wildlife Authority: protectionism, neoliberal capital accumulation, and community-based conservation. We find that oil extraction is legally permitted inside protected areas in Uganda, like many other African countries, and that the wildlife authority and oil companies are adapting to co-exist inside a protected area. Our primary argument is that neoliberal capital accumulation as a conservation policy actually makes protected areas more vulnerable to industrial exploitation because nature is commodified, allowing economic value and profitability of land uses to determine how nature is exploited. Our secondary argument is that the conditional nature of protected area access inherent within the protectionist policy permits oil extraction within Murchison Falls Protected Area. Finally, we argue that community-based conservation, as operationalized in Uganda, has no role in defending protected areas against oil industrialisation.

Does Arctic governance hold the key to achieving climate policy targets?

Science.gov (United States)

Forbis, Robert, Jr.; Hayhoe, Katharine

2018-02-01

Arctic feedbacks are increasingly viewed as the wild card in the climate system; but their most unpredictable and potentially dangerous aspect may lie in the human, rather than the physical, response to a warming climate. If Arctic policy is driven by agendas based on domestic resource development, the ensuing oil and gas extraction will ensure the failure of the Paris Agreement. If Arctic energy policy can be framed by the Arctic Council, however, its environmental agenda and fragmented governance structure offers the scientific community a fighting chance to determine the region’s energy future. Connecting Arctic climate science to resource economics via its unique governance structure is one of the most powerful ways the scientific community can protect the Arctic region’s environmental, cultural, and scientific resources, and influence international energy and climate policy.

Our present study was conducted to characterize the phytoconstituents present in the aqueous extract of Momordica charantia and evaluate the antimicrobial efficacy of silver-extract nanoparticles (Ag-Extract-NPs). Silver nanoparticles (AgNPs) were prepared by reducing AgNO 3; and NaBH 4 served as reducing agent. After screening of phytochemicals; AgNPs and aqueous extract were mixed thoroughly and then coated by polyaniline. These NPs were characterized by using Visual inspection, UV spectroscopy, FTIR, SEM and TEM techniques. Antimicrobial activities were assessed against Staphylococcus aureus, Salmonella typhi, Escherichia coli and Pseudomonas aeruginosa. Aqueous extract of M. charantia fruits contain alkaloid, phenol, saponin etc. UV-Vis spectrum showed strong absorption peak around 408 nm. The presence of -CH, -NH, -COOH etc. stretching in FTIR spectrum of Ag-Extract-NPs endorsed that AgNPs were successfully capped by bio-compounds. SEM and TEM result revealed that synthesized NPs had particle size 78.5-220 nm. Ag-Extract-NPs showed 34.6 ± 0.8 mm zone of inhibition against E. coli compared to 25.6 ± 0.5 mm for ciprofloxacin. Maximum zone of inhibition for Ag-Extract-NPs were 24.8 ± 0.7 mm, 26.4 ± 0.4 mm, 7.4 ± 0.4 mm for S. aureus, P. aeruginosa and S. typhi. We found that Ag-Extract-NPs have much better antibacterial efficacy than AgNPs and M. charantia extract has individually. It is also noticed that gram negative bacteria (except S. typhi) are more susceptible to Ag-Extract-NPs than gram positive bacteria. Ag-Extract-NPs showed strong antibacterial activity. In order to make a reliable stand for mankind, further study is needed to consider determining the actual biochemical pathway by which AgNPs-extracts exert their antimicrobial effect.

Environmental policies and risk finance in the green sector: Cross-country evidence

International Nuclear Information System (INIS)

Criscuolo, Chiara; Menon, Carlo

2015-01-01

This paper provides a detailed description of venture capital investment in the green sector across 29 countries over the period 2005–2010, and identifies the role that policies might play in explaining observed cross-country differences. The analysis is based on a deal-level database of businesses seeking financing, combined with indicators of renewable policies and government R&D expenditures. The econometric analysis relates the number of deals and their volumes in a country to deployment and supply policies using count data and limited dependent variable (Tobit) models. The results suggest that both supply side policies and environmental deployment policies, designed with a long-term perspective of creating a market for environmental technologies, are associated with higher levels of venture capital relative to more short-term fiscal policies. When focusing on policies related to renewable energy generation, the results confirm the positive association of generous feed-in tariffs (FITs) with venture capital investment. However, in the solar sector excessively generous FITs tend to discourage investment, perhaps reflecting a lack of credibility over the longer term. Thus, both sets of results point to long-term policy stability, sustainability and credibility as important policy features to ensure Venture capital backing of innovative and risky ventures in a country's green sector. -- Highlights: •Risk-finance in the green sector is likely to face more challenges than in other hi-tech sectors. •Supply and deployment policies are associated with more investments relative to fiscal policies. •FITs have a positive effect, but in the solar sector very generous FITs discourage investments

Determinants of Renewable Energy Innovation: Environmental Policies vs. Market Regulation

International Nuclear Information System (INIS)

Vona, Francesco; Nesta, Lionel; Nicolli, Francesco

2012-02-01

This paper carries out a comprehensive analysis of renewable energy innovations considering four mechanisms suggested by innovation models: 1. policy-inducement; 2. market structure; 3. demand and social cohesion- mainly proxied by income inequality; 4. characteristics of country knowledge base. For OECD countries and years 1970-2005, we build a unique dataset containing time-varying information on quality-adjusted patent production in renewable energy, the latter being a function of environmental policies, green R and D, entry barriers, knowledge stock, knowledge diversity and income inequality. We develop count data models using the Generalized Method of Moments (GMM) to account for endogeneity of policy support. Our synthetic policy index positively affects innovations especially in countries with deregulated energy markets and low entry barriers. The effect of entry barriers and inequality is negative and of similar magnitude as that of policy. Product market liberalization positively affects green patent generation, especially so when ambitious policies are adopted, when the initial level of public R and D expenditures and when the initial share of distributed energy generation is high. Our results are robust to alternative specifications, to the inclusion of technology-specific effects and to the use of quality-adjusted patents as dependent variables. In the latter case, the estimated effect of lowering entry barriers and of knowledge diversity almost double on citation count relatively to patent count. (authors)

Causality between public policies and exports of renewable energy technologies

International Nuclear Information System (INIS)

Sung, Bongsuk; Song, Woo-Yong

2013-01-01

This article investigates the causal relationship between public policies and exports of renewable energy technologies using panel data from 18 countries for the period 1991–2007. A number of panel unit root and cointegration tests are applied. Time series data on public policies and exports are integrated and cointegrated. The dynamic OLS results indicate that in the long run, a 1% increase in government R and D expenditures (RAD) increases exports (EX) by 0.819%. EX and RAD variables respond to deviations from the long-run equilibrium in the previous period. Additionally, the Blundell–Bond system generalized methods of moments (GMM) is employed to conduct a panel causality test in a vector error-correction mechanism (VECM) setting. Evidence of a bidirectional and short-run, and strong causal relationship between EX and the contribution of renewable energy to the total energy supply (CRES) is uncovered. CRES has a negative effect on EX, whereas EX has a positive effect on CRES. We suggest some policy implications based on the results of this study. - Highlights: ► We model VECM to test the Granger causality between the policies and the export. ► Technology-push policy has a positive impact on export in the long-run. ► There are the short-run causal relationships between market-pull policy and export

2005-01-01

In this paper, we develop multi-country indices of financial system stress and quality of financial policies and use them in regression analysis of the determinants of financial stress. We find that countries with higher quality of financial policies are better able to contain the effects of macroeconomic pressures on the overall level of stress in the financial system. They are also in a better position to ensure sustainable development of the financial system.

The objectives of this study were to determine best conditions for the extraction of phenolic compounds from fresh, frozen and lyophilized basil leaves. The acetone mixtures with the highest addition of acetic acid extracted most of the phenolic compounds when fresh and freeze-dried material have been used. The three times procedure was more effective than once shaking procedure in most of the extracts obtained from fresh basil leaves - unlike the extracts derived from frozen material. Surprisingly, there were not any significant differences in the content of phenolics between the two used procedures in the case of lyophilized basil leaves used for extraction. Additionally, the positive correlation between the phenolic compounds content and antioxidant activity of the studied extracts has been noted. It is concluded that the acetone mixtures were more effective than the methanol ones for polyphenol extraction. The number of extraction steps in most of the cases was also a statistically significant factor affecting the yield of phenolic extraction as well as antioxidant potential of basil leaf extracts.

Revival of Legacy of Tooke and Gibson: Implications for Monetary Policy

Directory of Open Access Journals (Sweden)

Rehman Atiq-ur

2015-05-01

Full Text Available The monetary policy rules used by central banks these days are based on the assumption that inflation could be reduced by increasing interest rate. On contrary, Tooke (1774-1858, the forefather of monetary economics, was of the view that the relationship between interest rate and inflation should be positive. His view was based on simple logic, ‘interest is a part of cost, and therefore, the increase in interest rate should increase inflation by increasing cost of production (Tooke, 1838’. Tooke’s view has got support from a number of empirical evidence including Gibson (1923 who found positive correlation between two variables for UK data over a period of 200 years. On the other hand, mainstream economic thinking on which the actual monetary practices are based ignored any possibility of positive relationship between interest rate and inflation throughout the history. The existence of Tooke’s cost side effects of monetary policy is a serious concern because if these effects exist than the use of monetary policy would be counterproductive. Using the data from entire globe, I attempt to explore the nature of relationship between the interest rate and inflation. I found that the data supports the perception of Tooke and Gibson and denies that the effectiveness of monetary policy currently adapted by the correlation between interest rate and inflation is positive. The results are robust to sample size, sample period, and various definitions of interest rate and inflation.

2003-01-01

The present work is aimed at studying the extraction systems based on neutral organophosphorus extractants - phosphorylated calixarenes for recovery of Pd and Tc together with Am and Cm from high-level radioactive wastes. Extraction of Pd, Tc and Eu (Am) was studied for phosphorylated calixarenes in meta-nitrobenzotrifluoride (NBTF). Main results are presented in Table. On the basis of available data one can suggest that type and position of phosphor-organic substituents are not so important for extraction of Tc and Pd, as for Eu and Am extraction. The phosphorylated at upper rim calix[4]arenas with small alkyl substituents at phosphorus atom are of prime interest for joint recovery of europium, americium, technetium and palladium. (authors)

2014-05-21

Cabernet Sauvignon and Shiraz grapes were sourced from different regions within Australia, and microvinified with a skin contact period of 6 days. Grape samples were extracted using two protocols: a 15% v/v ethanol, 10 g/L tartaric acid extract of gently crushed berries (wine-like, WL) and a 50% v/v ethanol, pH 2 extract of grape berry homogenate. It was found that in WL extracts, grape tannin and anthocyanin concentrations were strongly related to wine tannin, anthocyanin and color density achieved during the skin contact period. No relationship was observed for grape tannin concentration analyzed in homogenate extracts and wine tannin, but a strong, positive relationship was found for anthocyanin concentration. When the data obtained from homogenate extraction was treated separately by grape variety, a stronger relationship between grape and wine tannin concentration was observed. Tannin compositional analysis in wines indicated that higher tannin concentrations were due to the extraction of tannin of higher molecular mass during fermentation, most likely from grape skins.

Plans of mice and men: from bench science to science policy.

Simon, Ian D

2011-09-01

The transition from bench science to science policy is not always a smooth one, and my journey stretched as far as the unemployment line to the hallowed halls of the U.S. Capitol. While earning my doctorate in microbiology, I found myself more interested in my political activities than my experiments. Thus, my science policy career aspirations were born from merging my love of science with my interest in policy and politics. After receiving my doctorate, I accepted the Henry Luce Scholarship, which allowed me to live in South Korea for 1 year and delve into the field of science policy research. This introduction into science policy occurred at the South Korean think tank called the Science and Technology Policy Institute (STEPI). During that year, I used textbooks, colleagues, and hands-on research projects as my educational introduction into the social science of science and technology decision-making. However, upon returning to the United States during one of the worst job markets in nearly 80 years, securing a position in science policy proved to be very difficult, and I was unemployed for five months. Ultimately, it took more than a year from the end of the Luce Scholarship to obtain my next science policy position with the American Society for Microbiology Congressional Fellowship. This fellowship gave me the opportunity to work as the science and public health advisor to U.S. Senator Harry Reid. While there were significant challenges during my transition from the laboratory to science policy, those challenges made me tougher, more appreciative, and more prepared to move from working at the bench to working in the field of science policy.

The main findings are that while wicked and unruly problems create an urgent need for policy innovation, politicians are badly positioned to initiate, drive and lead...... this innovation. They are either locked into a dependency on policy advice from senior civil servants or locked out of more inclusive policy networks. In either case, they are insulated from fresh ideas and ultimately reduced to ‘policy-takers’ with limited engagement in policy innovation. Collaborative policy...

Chinese climate policy - Institutions and intent

Ramsay, William C.; Lesourne, Jacques

2011-06-01

Until the late 1990's, the balance of Chinese energy production and consumption was treated by the rest of the world as a net figure. No one knew what was going on inside the Chinese economy - it was a black box. As far as anyone was concerned, the Chinese would not soon be a major factor in world energy markets. Energy policy-makers realized how totally blind they were in 2004 when Chinese electricity production could not keep up with internal demand and the world experienced a surge in liquids demand as Chinese entrepreneurs fired up generator sets across the economy. No country has confronted the need to collect data and formulate coherent policy for nearly a billion and a half consumers. A number of institutional arrangements have succeeded each other until now, when stronger energy policy and administrative functions of the National Development and Reform Commission (NDRC) are gaining traction. NDRC vice-chairman Zhang Guobao has maintained a steady hand on Chinese energy-policy evolution for several years - overseeing the increasing coherence of Chinese domestic and international energy policy - but the tension with powerful state enterprises and other vested interests still effectively defies efforts to truly centralize Chinese national-level energy policy and program authority. This study identifies the nature of the forces that drive or constrain change within China's energy sector, and explores the Chinese approach to climate change. Contents: 1. The Institutions of Energy Governance in china. 2. China's Foreign Energy Policy. 3. China's position and policy on climate change

Grapefruit (Citrus paradisi) seed extract is generally used as naturopathic medications, supplements, antiseptic and disinfecting agents and also as preservatives in food and cosmetics products. In vitro studies have demonstrated that grapefruit seed extract has anti bacterial properties against a range of gram-positive and gram-negative organisms. Indonesian grapefruit, known as pomelo (C. maxima), has similar characteristics, contents and is under the same genus (Citrus) as grapefruit; however it has not been completely utilized as a preservative. In this work we analyze the antimicrobial activities of ethanolic extract of Indonesian pomelo (C. maxima) seeds and pulp compared to the grapefruit (C. paradisi) seeds and pulp ethanolic extract. Ethanolic extracts of pomelo and grapefruit seeds and pulp are investigated for activities against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Candida albicans. The level of antimicrobial effects is established using agar diffusion method. Both of the ethanolic do not show any antimicrobial activities against C. albicans. The ethanolic extract of pomelo seeds and pulp used in this research give positive results with growth inhibition effect on B. subtilis, S. aureus and E. coli. The zones of inhibition ranges from 22 - 30 mm in diameter, which is higher to grapefruit seeds and pulp ethanolic extract (17 - 25 mm). Ethanolic extract of pomelo seeds and pulp has an antimicrobial effect, which makes it a natural preparation for use as an alternative preservative for food and cosmetic.

Womenomics and Acrobatics: Why Japanese Feminists Remain Skeptical about Feminist State Policy

Directory of Open Access Journals (Sweden)

Ayako Kano

2018-03-01

Full Text Available Neoliberalism and conservative ideology have come together in Japan as ‘womenomics’, a state policy to boost women’s labour productivity as well as the nation’s birth rate. Feminists have responded with scepticism to this policy, proposed by the strongly conservative and nationalist Prime Minister, Shinzo Abe. The content of ‘womenomics’ includes a new law to promote the advancement of women to leadership positions, and reflects the government’s concern for Japan’s international standing. The demographic crisis of a rapidly aging society with a declining birth rate is another background to the policy. Policies to boost the birth rate have been hard to reconcile with policies to promote women in leadership positions in corporate life. The gendered division of labour and the structure of the labour market exacerbate problems as neoliberal reforms are introduced belatedly to Japan. The resistance to neoliberalism has come from conservatives, and thus feminists in Japan have had to perform complicated acrobatics. The long-term prospects depend on finding ways to promote equality in a potentially shrinking nation while continuing to resist the seductions of neoliberal state policies that purport to advance the interests of women.

This report is the summary of the 'investigation results concerning development policy and position of various coal liquefaction processes in Japan'. The purpose of this investigative research is primarily to clarify the position of coal energy in the future energy supply, technologies of converting coal to clean fuel as the form of coal energy utilization most suitable for Japan, and the position of coal liquefaction in such converting technologies, and also to decide on the policy of R and D on coal liquefaction process in Japan at present. Accordingly, this paper investigates the status quo of various liquefaction processes including the coal liquefaction technologies for which R and D are conducted under the Sunshine Project; making analysis/assessment from such viewpoint as clean process as environmental safeguard and a precondition for coal energy utilization, technical problems concerning coal import and transportation, and suitability for the present energy consumption structure centering on oil; and further, examining the position of coal liquefaction in the general effective utilization of coal as organic carbonaceous resources in the distant future.

The legume plant family (Fabaceae) is a potential source of antimicrobial phytochemicals. Molecular diversity in phytochemicals of legume extracts was enhanced by germination and fungal elicitation of seven legume species, as established by RP-UHPLC-UV-MS. The relationship between phytochemical composition, including different types of skeletons and substitutions, and antibacterial properties of extracts was investigated. Extracts rich in prenylated isoflavonoids and stilbenoids showed potent antibacterial activity against Listeria monocytogenes and methicillin-resistant Staphylococcus aureus at concentrations between 0.05 and 0.1% (w/v). Prenylated phenolic compounds were significantly (p<0.01) correlated with the antibacterial properties of the extracts. Furthermore, the position of the prenyl group within the phenolic skeleton also influenced the antibacterial activity. Overall, prenylated phenolics from legume seedlings can serve multiple purposes, e.g. as phytoestrogens they can provide health benefits and as natural antimicrobials they offer preservation of foods.

Climate policy and dependence on traded carbon

International Nuclear Information System (INIS)

Andrew, Robbie M; Peters, Glen P; Davis, Steven J

2013-01-01

A growing number of countries regulate carbon dioxide (CO 2 ) emissions occurring within their borders, but due to rapid growth in international trade, the products consumed in many of the same countries increasingly rely on coal, oil and gas extracted and burned in other countries where CO 2 is not regulated. As a consequence, existing national and regional climate policies may be growing less effective every year. Furthermore, countries that are dependent on imported products or fossil fuels are more exposed to energy and climate policies in other countries. We show that the combined international trade in carbon (as fossil fuels and also embodied in products) increased from 12.3 GtCO 2 (55% of global emissions) in 1997 to 17.6 GtCO 2 (60%) in 2007 (growing at 3.7% yr −1 ). Within this, trade in fossil fuels was larger (10.8 GtCO 2 in 2007) than trade in embodied carbon (6.9 GtCO 2 ), but the latter grew faster (4.6% yr −1 compared with 3.1% yr −1 for fuels). Most major economies demonstrate increased dependence on traded carbon, either as exports or as imports. Because energy is increasingly embodied in internationally traded products, both as fossil fuels and as products, energy and climate policies in other countries may weaken domestic climate policy via carbon leakage and mask energy security issues.

2016-01-01

Full Text Available Introduction: The Mental Health Strategy for Canada identified a need to enhance the collection of data on mental health in Canada. While surveillance systems on mental illness have been established, a data gap for monitoring positive mental health and its determinants was identified. The goal of this project was to develop a Positive Mental Health Surveillance Indicator Framework, to provide a picture of the state of positive mental health and its determinants in Canada. Data from this surveillance framework will be used to inform programs and policies to improve the mental health of Canadians. Methods: A literature review and environmental scan were conducted to provide the theoretical base for the framework, and to identify potential positive mental health outcomes and risk and protective factors. The Public Health Agency of Canada’s definition of positive mental health was adopted as the conceptual basis for the outcomes of this framework. After identifying a comprehensive list of risk and protective factors, mental health experts, other governmental partners and non-governmental stakeholders were consulted to prioritize these indicators. Subsequently, these groups were consulted to identify the most promising measurement approaches for each indicator. Results: A conceptual framework for surveillance of positive mental health and its determinants has been developed to contain 5 outcome indicators and 25 determinant indicators organized within 4 domains at the individual, family, community and societal level. This indicator framework addresses a data gap identified in Canada’s strategy for mental health and will be used to inform programs and policies to improve the mental health status of Canadians throughout the life course.

Solar power and policy powerlessness − perceptions of persuasion in distributed residential solar energy policy development

2017-01-01

Full Text Available Distributed residential solar energy (photovoltaic technologies have been praised as a mechanism to not only increase the penetration of renewable energy but engage the community in a clean energy revolution. In spite of this it is unclear how much potential there is for stakeholders to influence processes around the adoption of solar energy, including policy development and regulation. As part of a wider research project assessing the social acceptance of residential solar energy in Western Australia a variety of stakeholders, including public servants, network operators, Members of Parliament, energy advocates, renewable energy industry members and community members, were asked whether they thought they had the potential to influence solar policy. The objective of this research was to highlight positions of influence over policy development. In total 23 interviews with regional Western Australian householders and 32 interviews with members of industry and government were undertaken between May and October 2015. Most respondents believed that they had previously, or could in future, influence solar policy by taking advantage of networks of influence. However, stakeholders perceived as having policy influence did not necessarily demonstrate the capacity to influence policy beyond providing information to decision-makers, namely Cabinet members. Instead, networks of renewable energy advocates, industry and community members could apply political pressure through petitions, media coverage and liaising with parliamentarians to develop support for policy changes. Furthermore, while policies for the promotion of solar energy, and renewable energy more generally, could be implemented at various levels of government, only those policies delivered at the state level could address socio-political barriers to renewable energy adoption. These barriers include: a lack of political will and funding to overcome technical issues with network connection

Full Text Available The beginning of the XXI century was marked by a number of serious problems, including cancer, world hunger, environmental problems and increasing every year the problem of global terrorism, which poses a great threat to the security of the modern multipolar world. Uzbekistan today occupies a firm position in fight against terrorist threat. The principled position of Uzbekistan in the fight against terrorism is that “no country should exclude their participation in the fight against global terrorism, there must be no transit zones and "green corridors" for terrorist organizations”. The Central Asian region is one of the most vulnerable, because it is necessary to pay special attention to the strategy of the anti-terrorist security of the countries included in the structure of the Central Asian region. In this article, we consider the anti-terrorist policy of Uzbekistan in the framework of the regional anti-terrorist policy of the SCO.

Full Text Available Canada went through a tough discussion in July 2013 when it was revealed that between 1942 and 1952 unethical and harmful research was conducted on Aboriginal peoples, most of whom were children. Beyond simply condemning unethical research with Indigenous populations, we need to examine why this happened and understand what the implications and lessons are for "policy research" moving forward. Policy research is a powerful tool when conducted in the proper way. We must never lose sight of the reason we are engaged in the activity: to improve well-being through the improvement of understanding that leads to change. The research process must, itself, be part of the positive process.

Full Text Available Taiwan’s “government innovation policy resources” help enterprises expand innovation capacity by providing financial rewards, tax deductions, personnel training, and polities and facilities that encourage innovation. The results of this study show that “government innovation policy resources” is significantly and positively correlated with “technological innovation capacity” and “firm operating performance,” while the latter two are also positively correlated. Among the “government innovation policy resources,” financial rewards and personnel training have the most influence on expanding innovation capacity, which in turn benefits the enterprises’ ability to develop better products and have a positive effect on its operating performance and profitability.

Canada's energy perspectives and policies for sustainable development

International Nuclear Information System (INIS)

Hofman, Karen; Li Xianguo

2009-01-01

A regression analysis is performed to make projections for the Canadian energy production and consumption. These have been increasing and are projected to increase even further in the near future. The primary energy production and consumption are projected to increase by 52% and 34%, respectively, by 2025 over 2004 if business as usual. The amount of fossil energy resources is finite and the extraction, transportation and combustion of fossil fuels cause environmental pollution and climate change. On the other hand, energy plays an important role in the economic and social development of Canada. Canada can develop further from an energy balance point of view, but this alone cannot be sustainable, because of the negative consequences of the major energy use on the environment. Application of energy localization and diversification is a promising solution, but in order to reach that, better energy efficiency and more use of renewable energy are necessary. Instead of non-compulsory policies Canada's policy approach should have more compulsory policies. Only then Canada can be made to develop further in a sustainable manner

Full Text Available We use both reinforcement learning and deep learning to simultaneously extract entities and relations from unstructured texts. For reinforcement learning, we model the task as a two-step decision process. Deep learning is used to automatically capture the most important information from unstructured texts, which represent the state in the decision process. By designing the reward function per step, our proposed method can pass the information of entity extraction to relation extraction and obtain feedback in order to extract entities and relations simultaneously. Firstly, we use bidirectional LSTM to model the context information, which realizes preliminary entity extraction. On the basis of the extraction results, attention based method can represent the sentences that include target entity pair to generate the initial state in the decision process. Then we use Tree-LSTM to represent relation mentions to generate the transition state in the decision process. Finally, we employ Q-Learning algorithm to get control policy π in the two-step decision process. Experiments on ACE2005 demonstrate that our method attains better performance than the state-of-the-art method and gets a 2.4% increase in recall-score.

Adamantane di-1,3-carbamoyl methylphosphine oxide (CMPO) derivatives, where CMPO-groups connect with 1,3-positions of rigid adamantane platform by methylene and ethylene bridges, are synthesized, and their efficiency as extractants of americium(III) and europium(III) from nitric acid solutions is demonstrated. Distribution function of Am 3+ and Eu + during extraction from 3M HNO 3 are measured in the investigation of extraction properties. It is noted that first synthesized adamantane CMPO derivatives are more effective for the extraction of americium(III) and europium(III) from 3MHNO 3 [ru

Use of Comparative Case Study Methodology for US Public Health Policy Analysis: A Review.

Science.gov (United States)

Dinour, Lauren M; Kwan, Amy; Freudenberg, Nicholas

There is growing recognition that policies influence population health, highlighting the need for evidence to inform future policy development and reform. This review describes how comparative case study methodology has been applied to public health policy research and discusses the methodology's potential to contribute to this evidence. English-language, peer-reviewed articles published between 1995 and 2012 were sought from 4 databases. Articles were included if they described comparative case studies addressing US public health policy. Two researchers independently assessed the 20 articles meeting review criteria. Case-related characteristics and research design tactics utilized to minimize threats to reliability and validity, such as the use of multiple sources of evidence and a case study protocol, were extracted from each article. Although comparative case study methodology has been used to analyze a range of public health policies at all stages and levels, articles reported an average use of only 3.65 (out of 10) research design tactics. By expanding the use of accepted research design tactics, public health policy researchers can contribute to expanding the evidence needed to advance health-promoting policies.

Full Text Available The general objective of the study is to determine the effectiveness of ampalaya leaf extract against gastrointestinal parasites of native chicken. Specifically, it aimed to:(1to evaluate the anthelmintic property of ampalaya leaf extract in the treatment of gastro-intestinal parasites of native chicken;(2 find out the most effective variety of ampalaya leaves as purgatives for native chicken; and(3 to compare the efficacy of ampalaya leaf extract with commercial purgative in the treatment of gastro-intestinal parasites. A total of fifteen (15 experimental native chickens were used in each study which was distributed into five (5 treatments. For study 1 and 2, Commercial purgative (Piperazine dihydrocloride and commercial purgative (mebendasole, niclosamide and levamisole were used respectively as positive control. Based on the result of the study, ampalaya leaf extract shows comparable effect to positive control (Piperazine dihydrochloride in treating and controlling gastro-intestinal parasites of native chicken. However, commercial purgative with triple ingredient (mebendasole, niclosamide and levamisole shows more effective than the ampalaya extract. The researcher concludes that efficacy of ampalaya leaf extract as purgative is comparable to the effect of commercial purgative with single active ingreadient (Piperazine dihydrochloride, commercial purgative with triple active ingredients ( mebendasole, niclosamide and levamisole excelled over the ampalaya extract because of its multi-ingredients.

In 1992, Electricite de France - EDF decided to improve the degree to which radiological protection is incorporated in overall management of the utility and set itself the objective of ensuring the same level of protection for workers from contractors as for those from EDF. This decision was taken in a context marked by a deterioration in exposure figures for French plants and by the new recommendations issued by the ICRP. This document describes the policy adopted by EDF at both corporate and plant level to meet these objectives, by: (1) setting up management systems which were responsive but not cumbersome; (2) a broad policy of motivation; (3) the development and use of suitable tools. The document then describes some quite positive results of EDF`s ALARA policy, giving concrete examples and analyzing the changes in global indicators.

Positioning a patient lying-flat in the acute phase of ischaemic stroke may improve recovery and reduce disability, but such a possibility has not been formally tested in a randomised trial. We therefore initiated the Head Position in Stroke Trial (HeadPoST) to determine the effects of lying-flat (0°) compared with sitting-up (≥ 30°) head positioning in the first 24 hours of hospital admission for patients with acute stroke. We plan to conduct an international, cluster randomised, crossover, open, blinded outcome-assessed clinical trial involving 140 study hospitals (clusters) with established acute stroke care programs. Each hospital will be randomly assigned to sequential policies of lying-flat (0°) or sitting-up (≥ 30°) head position as a 'business as usual' stroke care policy during the first 24 hours of admittance. Each hospital is required to recruit 60 consecutive patients with acute ischaemic stroke (AIS), and all patients with acute intracerebral haemorrhage (ICH) (an estimated average of 10), in the first randomised head position policy before crossing over to the second head position policy with a similar recruitment target. After collection of in-hospital clinical and management data and 7-day outcomes, central trained blinded assessors will conduct a telephone disability assessment with the modified Rankin Scale at 90 days. The primary outcome for analysis is a shift (defined as improvement) in death or disability on this scale. For a cluster size of 60 patients with AIS per intervention and with various assumptions including an intracluster correlation coefficient of 0.03, a sample size of 16,800 patients at 140 centres will provide 90 % power (α 0.05) to detect at least a 16 % relative improvement (shift) in an ordinal logistic regression analysis of the primary outcome. The treatment effect will also be assessed in all patients with ICH who are recruited during each treatment study period. HeadPoST is a large international clinical trial in

Energy policies of IEA countries. Canada 1996 review

International Nuclear Information System (INIS)

1996-01-01

This IEA report provides a comprehensive, in-depth assessment of the energy policies of Canada, including recommendations on future policy developments. The report acknowledges the marked shift of federal energy policy in the last decade away from heavy intervention to a more market-based approach. This has increased the strength and competitive position of Canada's energy producers, especially in oil and gas, and has provided more choice for consumers. Electricity, however, is an area that could benefit from a more market-based policy orientation. Federal provincial co-ordination is of fundamental importance. Other key issues highlighted in the review include the opportunities and challenges of international agreements on the environment, which increasingly drive energy policy decision-making; the adequacy and effectiveness of programmes to promote energy efficiency; and the balance and direction of energy research and development efforts. This report forms part of a series of periodic in-depth reviews conducted and discussed by the IEA Member countries on a four-year cycle. Short reviews of energy policy developments in all twenty-three Member countries are published annually in Energy Policies of IEA Countries. (author)

Let's dance: Organization studies, medical sociology and health policy.

Currie, Graeme; Dingwall, Robert; Kitchener, Martin; Waring, Justin

2012-02-01

This Special Issue of Social Science & Medicine investigates the potential for positive inter-disciplinary interaction, a 'generative dance', between organization studies (OS), and two of the journal's traditional disciplinary foundations: health policy and medical sociology. This is both necessary and timely because of the extent to which organizations have become a neglected topic within medical sociology and health policy analysis. We argue there is need for further and more sustained theoretical and conceptual synergy between OS, medical sociology and health policy, which provides, on the one-hand a cutting-edge and thought-provoking basis for the analysis of contemporary health reforms, and on the other hand, enables the development and elaboration of theory. We emphasize that sociologists and policy analysts in healthcare have been leading contributors to our understanding of organizations in modern society, that OS enhances our understanding of medical settings, and that organizations remain one of the most influential actors of our time. As a starting point to discussion, we outline the genealogy of OS and its application to healthcare settings. We then consider how medical sociology and health policy converge or diverge with the concerns of OS in the study of healthcare settings. Following this, we focus upon the material environment, specifically the position of business schools, which frames the generative dance between OS, medical sociology and health policy. This sets the context for introducing the thirteen articles that constitute the Special Issue of Social Science & Medicine. Copyright © 2011 Elsevier Ltd. All rights reserved.

Bosch, Xavier; Hernández, Cristina; Pericas, Juan M.; Doti, Pamela; Marušić, Ana

2012-01-01

Background It is not clear which research misconduct policies are adopted by biomedical journals. This study assessed the prevalence and content policies of the most influential biomedical journals on misconduct and procedures for handling and responding to allegations of misconduct. Methods We conducted a cross-sectional study of misconduct policies of 399 high-impact biomedical journals in 27 biomedical categories of the Journal Citation Reports in December 2011. Journal websites were reviewed for information relevant to misconduct policies. Results Of 399 journals, 140 (35.1%) provided explicit definitions of misconduct. Falsification was explicitly mentioned by 113 (28.3%) journals, fabrication by 104 (26.1%), plagiarism by 224 (56.1%), duplication by 242 (60.7%) and image manipulation by 154 (38.6%). Procedures for responding to misconduct were described in 179 (44.9%) websites, including retraction, (30.8%) and expression of concern (16.3%). Plagiarism-checking services were used by 112 (28.1%) journals. The prevalences of all types of misconduct policies were higher in journals that endorsed any policy from editors’ associations, Office of Research Integrity or professional societies compared to those that did not state adherence to these policy-producing bodies. Elsevier and Wiley-Blackwell had the most journals included (22.6% and 14.8%, respectively), with Wiley journals having greater a prevalence of misconduct definition and policies on falsification, fabrication and expression of concern and Elsevier of plagiarism-checking services. Conclusions Only a third of top-ranking peer-reviewed journals had publicly-available definitions of misconduct and less than a half described procedures for handling allegations of misconduct. As endorsement of international policies from policy-producing bodies was positively associated with implementation of policies and procedures, journals and their publishers should standardize their policies globally in order to

This study assessed the prevalence and content policies of the most influential biomedical journals on misconduct and procedures for handling and responding to allegations of misconduct.We conducted a cross-sectional study of misconduct policies of 399 high-impact biomedical journals in 27 biomedical categories of the Journal Citation Reports in December 2011. Journal websites were reviewed for information relevant to misconduct policies.Of 399 journals, 140 (35.1% provided explicit definitions of misconduct. Falsification was explicitly mentioned by 113 (28.3% journals, fabrication by 104 (26.1%, plagiarism by 224 (56.1%, duplication by 242 (60.7% and image manipulation by 154 (38.6%. Procedures for responding to misconduct were described in 179 (44.9% websites, including retraction, (30.8% and expression of concern (16.3%. Plagiarism-checking services were used by 112 (28.1% journals. The prevalences of all types of misconduct policies were higher in journals that endorsed any policy from editors' associations, Office of Research Integrity or professional societies compared to those that did not state adherence to these policy-producing bodies. Elsevier and Wiley-Blackwell had the most journals included (22.6% and 14.8%, respectively, with Wiley journals having greater a prevalence of misconduct definition and policies on falsification, fabrication and expression of concern and Elsevier of plagiarism-checking services.Only a third of top-ranking peer-reviewed journals had publicly-available definitions of misconduct and less than a half described procedures for handling allegations of misconduct. As endorsement of international policies from policy-producing bodies was positively associated with implementation of policies and procedures, journals and their publishers should standardize their policies globally in order to increase public trust in the

Full Text Available The purpose of this research is to quantitatively evaluate the growth phase, position, and priorities of the industrialization policy management of the construction industry at firm level. The goal is to integrate quantitative dynamics into the policy-making process for sustainable policy development in future China. This research proposes an integrated framework, including growth management model and industrial policy evaluation method, to identify the challenges of construction industrialization and policy management. The research applies the mixed system method, which includes entropy method and average score method, to analyze the growth stage and major impact indexes targeting 327 survey samples. The empirical results show that the proposed conceptual framework and policy evaluation method could effectively determine the growth position and directions of the construction industrialization. For verification purpose, the study uses the local industry data from Shaanxi Province, China. The calculation results substantiate that the construction industry is in the middle section of the third growth phase. The comparison of the results from statistical methods shows that the local construction industry still needs substantial effort in policy management to improve its sustainable industrialization level. As countermeasures, the policy priorities should concentrate on: (1 enhancing effective cooperation among universities, research institutions and enterprises; (2 improving actions towards technology transfer into productivity; and (3 encouraging market acceptance of construction industrialization. This research complements the existing literature of policy evaluation of construction industrialization. Moreover, it provides theoretical and operational steps on industry policy evaluation and growth management framework, with accurate and ample data analysis on firm-level survey. Researchers and policy makers can use this research for further

Lencucha, Raphael; Drope, Jeffrey

2015-01-01

This paper highlights two salient challenges at the intersection of tobacco control and macroeconomic policy-making: (i) the use of trade and investment disputes to undermine and/or stall tobacco control legislation and (ii) the inconsistency, and thus unpredictability, of country positions across the two spheres. In the interest of improving international policy coherence, the authors suggest possible solutions to these two challenges at the national and intergovernmental levels. PMID:23723441

2018-03-01

This study seeks to make a deep, systematic analysis of the urgency of implementing elements in the implementation of public health policies, especially in the field of mother and child in Bandung City, West Java. This study is important to evaluate whether the government services on maternal and child health is sufficient or not. With the descriptive-qualitative method, this study presents a discussion of how the implementers interact with the community as their targets in implementing public health programs in Bandung City so that their presence is indispensable. With theories of implementation of policies and health campaign, the data was obtained and showed that (a) the unity of the coordination and uniformity of information services, and a network of cooperation in public health institutions, in the Government of Bandung City, have been performed well; (b) in getting their rights the targets are highly motivated for the services of public health and some of them function to be the volunteers to assist local health policy implementers. However, the lack of health care workers who were directly addressing maternal and child health was perceived by the public so well that this study recommends the convening of additional formal health workers in the community.

EFFECTS OF MONETARY POLICY IN ROMANIA - A VAR APPROACH

2012-10-01

Full Text Available Understanding how monetary policy decisions affect inflation and other economic variables is particularly important. In this paper we consider the implications of monetary policy under the inflation targeting regime in Romania, based on an autoregressive vector method including recursive VAR and structural VAR (SVAR. Therefore, we focus on assessing the extent and persistence of monetary policy effects on gross domestic product (GDP, price level, extended monetary aggregate (M3 and exchange rate. The main results of VAR analysis reflect a negative response of consumer price index (CPI, GDP and M3 and positive nominal exchange rate behaviour to a monetary policy shock, and also a limited impact of a short-term interest rate shock in explaining the consumer prices, production and exchange rate fluctuations.

Work-life balance and family friendly policies

Directory of Open Access Journals (Sweden)

Janine Chapman

2013-12-01

Full Text Available This paper presents Australian and international research on work-life interaction. We review the work-life policies and practices that are likely to have the greatest impact on work-life outcomes, specifically reducing the negative impact of work on other life domains (work-life interference, and enhancing the positive effect (work-life facilitation. The review addresses four policy areas common in work-life studies of the general workforce: employee-centered flexible work practices; working hours (e.g. access to part-time work; paid and unpaid leave (e.g. parental leave; and access to childcare. It then considers the work-life literature related to two specific industries – the Australian public sector, and health and social services – to identify work-life issues and practices specific to each industry. We then conclude with a general discussion of challenges associated with the policy-practice gap, focusing particularly on work intensification and the role of organisational culture as the catalyst for policy uptake and effectiveness.

Global climate change policies. An analysis of CDM policies with an adapted GTAP model

International Nuclear Information System (INIS)

Wang, Shunli

2004-01-01

In the context of the relationships between spatial-economic interaction and global warming just discussed, this study aims to analyze the Clean Development Mechanisms (CDM) policies from an economic point of view. The research question of this study is formulated as follows: What will be the impacts of clirnate change policies, in particular CDM policies, on the economic performance of (groups of) countries in our global economic system, taking spatial interaction and general equilibrium effects into account? The purpose of addressing the issue of economic performance for (groups of) countries in the economic system is not just to identify winners and losers from international treaties. Rather, winning or losing may even determine the implementation and willingness of individual countries to participate in international environmental treaties, as illustrated by the recent withdrawal of the US from the Kyoto Protocol. By analyzing the economic impacts of an international environmental treaty for individual (groups of) countries, the framework that will be used to analyze this research question may be useful to determine the attractiveness of some global environmental policies, both for the world as a whole and for individual (groups of) countries. The research question will be answered by dividing it into six subquestions: (1) What is the position of CDM policies in the broad context of climate policy regimes?; (2) How should the relationship between human behavior and the physical environment be ideally modeled from an economic perspective? (3) How should the spatial dimension be incorporated in this framework of interaction between the economic and ecological system?; (4) How can climate change issues be incorporated in general equilibrium models in general, and in GTAP-E (extension of the Global Trade Analysis Project) in particular?; (5) How can CDM policies be implemented in the GTAP-E model?; and (6) What are the impacts of these climate change policies on

Agricultural policy, food policy, and communicable disease policy.

Science.gov (United States)

Grant, Wyn

2012-12-01

Food and agricultural policy is an essential element of a communicable disease policy. The European Union has developed a more systematic and broadly based interest in questions of food safety and animal health and welfare linked to modernization of the Common Agricultural Policy, reflected in a new treaty obligation on animal welfare. Following the bovine spongiform encephalopathy crisis, moves were made to create a European competency, but implementation and enforcement resources reside with the member states. The European Animal Health Strategy is meant to lead to an EU animal health law, but this has already been constrained by fiscal austerity. The development of such a law may lead to a lowest common denominator formula that does little to enhance consumer protection or improve animal welfare. This is an inherent risk with top-down forms of Europeanization; more attention should be paid to lessons to be learned from bottom-up initiatives of the type used to counteract the bovine diarrhea virus. There will always be a tension among what is good policy for reducing the incidence of communicable disease, policy that is popular with EU citizens, and policy that is acceptable to member states.

AWHONN Position Statement. Intimate partner violence.

Science.gov (United States)

2015-01-01

The Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) opposes laws and other policies that require nurses to report the results of screening for intimate partner violence (IPV) to law enforcement or other regulatory agencies without the consent of the woman who experiences the IPV. Nurses and other health care professionals, however, should become familiar with laws on mandatory reporting in their states and comply as applicable. Women should be universally screened for IPV in private, safe settings where health care is provided. Nurses are ideally positioned to screen for IPV for the purpose of initiating a referral for services and support when applicable. To protect the woman's safety, AWHONN supports policies that require a woman's consent before reporting occurs.

The complexity and ambivalence of immigration attitudes: ambivalent stereotypes predict conflicting attitudes toward immigration policies.

Science.gov (United States)

Reyna, Christine; Dobria, Ovidiu; Wetherell, Geoffrey

2013-07-01

Americans' conflicted attitudes toward immigrants and immigration has stymied immigration reform for decades. In this article, we explore the nuanced nature of stereotypes about immigrants and how they relate to ambivalent attitudes toward immigrant groups and the disparate array of immigration policies that affect them. Using item response theory and multiple regression analysis, we identified and related stereotypes of different immigrant groups to group-based and policy attitudes. Results demonstrate that ambivalent stereotypes mapped onto ambivalent group-based and immigration policy attitudes. Specifically, stereotypes that portray groups in positive or sympathetic ways predicted positive attitudes toward the group and more supportive attitudes toward policies that facilitate their immigration to the United States. Conversely, negative qualities predicted negative attitudes toward the same group and support for policies that prevent the group from immigrating. Results are discussed in light of current theory related to stereotype content, complementarity of stereotypes, and broader implications for immigration attitudes and policy.

Negative hydrogen ion beam extraction from an AC heated cathode driven Bernas-type ion source

Energy Technology Data Exchange (ETDEWEB)

Okano, Y.; Miyamoto, N.; Kasuya, T.; Wada, M.

2015-04-08

A plasma grid structure was installed to a Bernas-type ion source used for ion implantation equipment. A negative hydrogen (H{sup −}) ion beam was extracted by an AC driven ion source by adjusting the bias to the plasma grid. The extracted electron current was reduced by positively biasing the plasma grid, while an optimum plasma grid bias voltage for negative ion beam extraction was found to be positive 3 V with respect to the arc chamber. Source operations with AC cathode heating show extraction characteristics almost identical to that with DC cathode heating, except a minute increase in H{sup −} current at higher frequency of cathode heating current.

2012-01-01

Full Text Available This paper reports part of a bigger study whose aim was to develop an empowerment model that could be used to enhance nurse leaders’ participation in health policy development. A Delphi survey was applied which included the following criteria: expert panelists, iterative rounds, statistical analysis, and consensus building. The expert panelists were purposively selected and included national nurse leaders in leadership positions at the nursing professional associations, nursing regulatory bodies, ministries of health, and universities in East Africa. The study was conducted in three iterative rounds. The results reported here were gathered as part of the first round of the study and that examined the extent of nurse leaders’ participation in health policy development. Seventy-eight (78 expert panelists were invited to participate in the study, and the response rate was 47%. Data collection was done with the use of a self-report questionnaire. Data analysis was done by use of SPSS and descriptive statistics were examined. The findings indicated that nurse leaders participate in health policy development though participation is limited and not consistent across all the stages of health policy development. The recommendations from the findings are that health policy development process needs to be pluralistic and inclusive of all nurse leaders practicing in positions related to policy development and the process must be open to their ideas and suggestions.

At present, China has achieved an initial establishment and gradual implementation of a framework for national essential drugs policy. With the further implementation of the national essential drugs policy, it is not clear how the policy works, whether it achieves the original intention of essential drugs policy, and what impact essential drugs policy exerts on the primary health care system. In view of it, we conducted a field research on sample areas of Shandong Province to understand the conditions of the implementation of the essential drugs policy in Shandong Province. From three perspectives of medical institutions, patients and medical staff, this thesis analyzes the impact of essential drugs policy on village-level and township-level health service system, summarizes the effectiveness of implementing essential drugs policy, discovers the problems of various aspects and conducts an in-depth analysis of the causes, and puts forward feasible suggestions to provide reference for improving the essential drugs policy. The assessment results show that the implementation of essential drugs policy in Shandong Province has played a positive role in promoting the sound development of the primary health care system, changed the situation of covering hospital expenses with medicine revenue in the past, contributed to the return of medical institutions to public welfare, and reduced the patient's economic burden of disease. But there emerge many problems as follows: impact on the doctor's diagnosis and treatment due to incompleteness of drug types, and distribution not in place, patient loss and operational difficulty of village clinic. Thus, this thesis makes recommendations of drugs catalog formulation, drug procurement, sales and use, and meanwhile points out that the supporting financial compensation policy and performance appraisal policy and other measures in place are a prerequisite for a positive role of essential drugs policy.

Full Text Available The authors consider the core areas of Lithuanian foreign policy. Special attention is paid to the adjustment of the major foreign policy vector, which concentrated earlier on the cooperation with the United States of America and strategic partnership with the Republic of Poland. The article analyses the attempts of Lithuanian president Dalia Grybauskaitė to formulate the so-called «new foreign policy» based on the multivector approach to the intergovernmental cooperation. This research is timely because of an increasing influence of small states on foreign policy decision-making within the European Union. It emphasizes the need to analyse foreign policy priorities of the Baltic States and Central and Eastern European countries and to identify the dominant trends in the international policy in the region in order to forecast further development at European and global levels. This objective is achieved with the help of an integrated approach with elements of interdisciplinary research. Special attention is paid to the comparative-historical approach, which facilitates the analysis of the relations between the Republic of Lithuania and the neighbouring states and its principal partners. Alongside traditional methods of historical research, this work employs such methods as participant observation, content and event analysis, and simultaneous and comparative analysis. The research and practical significance of this work is explained by its emphasis on the need to apply an additional theoretical framework to studies into the foreign policy initiatives of the Republic of Lithuania in the international arena. While earlier they were determined by the value (democratic approach, which was a reflection of American realism, today an increasingly important factor is the personality of the president, who does not always positively influence the changing policy of the country. The results of the research contribute substant

Welfare implications of the renewable fuel standard with an integrated tax-subsidy policy

International Nuclear Information System (INIS)

Skolrud, Tristan D.; Galinato, Gregmar I.

2017-01-01

This paper derives the optimal integrated tax-subsidy policy where one input is taxed and revenues are used to subsidize the use of a substitute input to reduce greenhouse gas emissions given the existing policies under the Renewable Fuel Standard policies. We measure the welfare effects and impact on cellulosic ethanol production after implementing the tax-subsidy policy using a general equilibrium model. A revenue-neutral integrated tax-subsidy scheme leads to a small positive tax rate for crude oil and a large positive subsidy for cellulosic ethanol because the former has a larger emissions coefficient than the latter. The overall welfare effects of an integrated tax subsidy scheme are less than a 1% increase for the economy but the growth in the cellulosic ethanol industry could range from 28% to 238% because the revenues from taxing crude oil are directly used to subsidize cellulosic ethanol production. - Highlights: • We derive an integrated tax-subsidy interacting with the Renewable Fuel Standard. • The policy is revenue-neutral. • Policy results in a small crude oil tax and a large cellulosic ethanol subsidy. • Simulations indicate a welfare-increasing optimal policy. • Growth in the cellulosic ethanol industry ranges from 28% to 238%.

Fogarty, Andrea S; Chapman, Simon

2012-12-01

To describe television news coverage between 2005 and 2010 of alcohol, health and relevant alcohol-control policies, with a view to informing policy advocacy. A content analysis of all alcohol stories archived by the Australian Health News Research Collaboration. We recorded what triggered a news item, the main topics covered, whether risks to health were communicated, whether alcohol-control policies were featured and which news-actors appeared. We identified 612 stories, where 69.2% were triggered by a particular newsworthy incident or the release of new findings. The most frequently reported alcohol stories were focused on associated harms (30.2%) and 'binge drinking' (19.0%). A majority (75.3%) reported a variety of positive and negative health effects, yet mainly focused on short-term consequences. Combined, 63% mentioned an alcohol-control policy, yet no one particular policy was featured in more than 10% of all stories. The most commonly featured news-actors included public-health professionals (50.0%), members of affected communities (28.4%) and government representatives (24.3%) Problems related to alcohol were well-established foci of news attention and reportage and covered a broad spectrum of issues related to public health goals, yet less coverage centred on long-term health consequences or effective policy solutions. Future policy advocacy could focus on moving the debate away from simple problem definition to better communication of long-term health risks, existing policies, and evidence of their effectiveness and arguments for their adoption. Future research might consider audience understanding of the information. © 2012 The Authors. ANZJPH © 2012 Public Health Association of Australia.

Policy Statements Issued by Scientific Societies: Why Less can be More

Science.gov (United States)

Folger, P. F.

2001-12-01

The results of hydrological research are increasingly important to decision-makers grappling with problems as diverse as global climate change, non-point source pollution, extreme weather events, and damage from flooding. In some cases scientific aspects of these problems are interwoven with economic, political and social disputes, and policy makers often seek the consensus scientific opinion to help shape the debate. Policy or position statements issued by scientific societies like AGU can embody scientific consensus and thus inform the public and policy makers. But this is not always the case. The potential for creating public misunderstanding is ever present. Therefore, the process leading to a policy statement needs to be deliberative, inclusive to the extent possible, and circumspect. In contrast to advocacy organizations or trade groups, as a learned society AGU and members acting on its behalf should only advocate positions on political or social issues that are based solely on available geophysical data and recognized scientific debate. That does not mean that AGU and other scientific societies must refrain from entering a political debate. AGU has a responsibility to its members to adopt positions of advocacy on geophysical science issues based on their intrinsic merits and needs. However, a learned society like AGU should state only what is credible about the scientific aspects of a political debate and not overstep its authority as an objective source of analysis and commentary for the geophysical sciences. Before adopting an advocacy position, AGU's volunteers follow a process that includes checks and balances so that the final statement is based on sound scientific issues and reflects the interests of the Union as a whole. Any AGU member or committee can propose a position statement, but the Committee on Public Affairs (COPA) decides whether the proposal fall within the guidelines for advocacy. If it does and if COPA considers the issue worthy of an

College sport organizations and associations endorse concussion-management protocols and policies. To date, little information is available on concussion policies and practices at community college institutions. To assess and describe current practices and policies regarding the assessment, management, and return-to-play criteria for sport-related concussion (SRC) among member institutions of the California Community College Athletic Association (CCCAA). Cross-sectional study. Web-based survey. A total of 55 head athletic trainers (ATs) at CCCAA institutions. Data about policies, procedures, and practices regarding SRC were collected over a 3-week period in March 2012 and analyzed using descriptive statistics, the Fisher exact test, and the Spearman test. Almost half (47%) of ATs stated they had a policy for SRC assessment, management, and return to play at their institution. They reported being in compliance with baseline testing guidelines (25%), management guidelines (34.5%), and return-to-play guidelines (30%). Nearly 31% of ATs described having an SRC policy in place for academic accommodations. Conference attendance was positively correlated with institutional use of academic accommodations after SRC (r = 0.44, P = .01). The number of meetings ATs attended and their use of baseline testing were also positively correlated (r = 0.38, P = .01). At the time of this study, nearly half of CCCAA institutions had concussion policies and 31% had academic-accommodation policies. However, only 18% of ATs at CCCAA institutions were in compliance with all of their concussion policies. Our findings demonstrate improvements in the management of SRCs by ATs at California community colleges compared with previous research but a need for better compliance with SRC policies.

Researchers have studied the impact of different welfare state regimes, and particularly family policy regimes, on gender equality. Very little research has been conducted, however, on the association between different family policy regimes and children's well-being. This article explores how the different family policy regimes of twenty OECD countries relate to children's well-being in the areas of child poverty, child mortality, and educational attainment and achievement. We focus specifically on three family policies: family cash and tax benefits, paid parenting leaves, and public child care support. Using panel data for the years 1995, 2000, and 2005, we test the association between these policies and child well-being while holding constant for a number of structural and policy variables. Our analysis shows that the dual-earner regimes, combining high levels of support for paid parenting leaves and public child care, are strongly associated with low levels of child poverty and child mortality. We find little long-term effect of family policies on educational achievement, but a significant positive correlation between high family policy support and higher educational attainment. We conclude that family policies have a significant impact on improving children's well-being, and that dual-earner regimes represent the best practice for promoting children's health and development.

2012-01-01

Background eHealth is widely used as a tool for improving health care delivery and information. However, distinct policies and strategies are required for its proper implementation and integration at national and international levels. Objective To determine the scope of policy issues faced by individuals, institutions, or governments in implementing eHealth programs. Methods We conducted a structured review of both peer-reviewed and gray literature from 1998–2008. A Medline search for peer-reviewed articles found 40 papers focusing on different aspects of eHealth policy. In addition, a Google search found 20 national- and international-level policy papers and documents. We reviewed these articles to extract policy issues and solutions described at different levels of care. Results The literature search found 99 policy issues related to eHealth. We grouped these issues under the following themes: (1) networked care, (2) interjurisdictional practice, (3) diffusion of eHealth/digital divide, (4) eHealth integration with existing systems, (5) response to new initiatives, (6) goal-setting for eHealth policy, (7) evaluation and research, (8) investment, and (9) ethics in eHealth.

Kossova, Tatiana; Kossova, Elena; Sheluntcova, Maria

2018-08-01

In this paper, we consider anti-smoking policy in Russia and the socioeconomic factors that influence an individual's decision to smoke. Among various factors, we investigate the individual time preferences of Russians. To estimate individual time preferences, we use an experiment in which survey respondents are given hypothetical money prizes. We find that being middle-aged, being unmarried and having parents who smoke are positively correlated with both men and women's likelihood of taking up smoking in Russia. We consider the possible endogeneity of an individual's health status and find a positive relationship between smoking and the time preferences of Russians. Our findings confirm that decisionmakers should devote their efforts primarily to developing restrictive anti-smoking policy. The choice of policy measures should be guided by the individual characteristics of target population groups. Social advertising, public lectures and preventive care should be actively engaged in forming public attitudes towards smoking. Copyright © 2018 Elsevier Ltd. All rights reserved.

There have been many studies to detect infectious diseases with the molecular genetic method. This study presents an automation process for a DNA extraction system based on microfluidics and magnetic bead, which is part of a portable molecular genetic test system. This DNA extraction system consists of a cartridge with chambers, syringes, four linear stepper actuators, and a rotary stepper actuator. The actuators provide a sequence of steps in the DNA extraction process, such as transporting, mixing, and washing for the gene specimen, magnetic bead, and reagent solutions. The proposed automation system consists of a PC-based host application and an Arduino-based controller. The host application compiles a G code sequence file and interfaces with the controller to execute the compiled sequence. The controller executes stepper motor axis motion, time delay, and input-output manipulation. It drives the stepper motor with an open library, which provides a smooth linear acceleration profile. The controller also provides a homing sequence to establish the motor's reference position, and hard limit checking to prevent any over-travelling. The proposed system was implemented and its functionality was investigated, especially regarding positioning accuracy and velocity profile.

Political implications of US nuclear-export-policy development

International Nuclear Information System (INIS)

Johnson-Freese, J.S.

1981-01-01

There has been a great deal of international debate regarding how effective strict export controls on nuclear-energy supplies are toward a non-proliferation goal. With the Carter Administration, the debate was heightened by a new, more-vigorous US nuclear-export policy, much of which was codified by the Nuclear Non-Proliferation Act of 1978 (NNPA). Because of the US position in both the international non-proliferation regime and nuclear export market, the NNPA has had far-reaching consequences. The thesis of this paper is that a nuclear-export policy that fails to consider its short-term ramifications, as the NNPA has been accused of, will be self-defeating. If the US wants a viable worldwide nuclear non-proliferation policy, it must first direct its efforts toward building a domestic non-proliferation consensus, and then worldwide, rather than first setting a highly controversial policy and expecting other nations to fall into line. This work provides a comprehensive case study of US nuclear-export policy between the years 1976 to 1980 in support of the thesis. Further, the behavior and impact of the interest groups which seem to shape US nuclear-export policies is examined, and recommendations made regarding the role of groups in nuclear policy-making and implementation. Finally, recommendations are made regarding non-proliferation policy for the future, as it relates to nuclear exports

Roy, Pragyan; Das, Bhagyalaxmi; Mohanty, Abhipsa; Mohapatra, Sujata

2017-11-01

In this study, green synthesis of silver nanoparticles was done using leaf extracts of Azadirachta indica. The flavonoids and terpenoids present in the extract act as both reducing and capping agent. Microbes ( Escherichia coli and Gram-positive bacteria) were isolated from borewell water using selective media. The silver nanoparticles showed antimicrobial activities against Gram-positive bacteria and E. coli. However the silver nanoparticles were more effective against E. coli as compared to Gram-positive bacteria. Various techniques were used to characterize synthesized silver nanoparticles such as DLS and UV-visible spectrophotometer. The absorbance peak was in the range of 420-450 nm, that varied depending upon the variation in the concentration of neem extract. This is a very rapid and cost-effective method for generation of silver nanoparticle at room temperature, however, its exact dose in water purification has to be determined.

Extraction of Maxillary Central Incisors: An Orthodontic-Restorative Treatment

Hedayati, Zohreh; Zare, Maryam; Bahramnia, Fateme

2014-01-01

Malformed central incisors with poor prognosis could be candidates for extraction especially in crowded dental arches. This case report refers to a 12-year-old boy who suffered from malformed upper central incisors associated with severe attrition. Upper lateral incisors were positioned palatally and canines were rotated and positioned in the high buccal area. The patient had class II malocclusion and space deficiency in both dental arches. Due to incisal wear and malformed short maxillary central incisors and the need for root canal therapy with a major crown build-up, these teeth were extracted. The maxillary lateral incisors were substituted. Thus the maxillary canines were substituted for lateral incisors and the first premolars were substituted for canines. In the lower dental arch the first bicuspids were extracted. Composite resin build-up was performed on the maxillary lateral incisors and canines. This allowed for the crowding and the malocclusion to be corrected. Subsequent gingivectomy improved the patient's gingival margins and smile esthetics one month after orthodontic therapy.

Canadian Drug Policy and the Reproduction of Indigenous Inequities

Directory of Open Access Journals (Sweden)

Shelley G. Marshall

2015-01-01

Full Text Available Canada’s federal drug policy under the Harper government (2006 to present is “tough on crime” and dismissive of public health and harm reduction approaches to problematic drug use. Drawing on insights from discourse and critical race theories, and Bacchi’s (2009 poststructural policy analysis framework, problematic representations in Canada’s federal drug policy discourse are examined through proposed and passed legislation, government documents, and parliamentary speaker notes. These problem representations are situated within their social, historical, and colonial context to demonstrate how this policy is poised to intersect with persistent racial inequalities that position Indigenous peoples for involvement with illicit substances and markets, and racialized discourses and practices within law and law enforcement that perpetuate Indigenous over-representation in the criminal justice system.

Fertility and Public Policies - Evidence from Norway and Finland

Directory of Open Access Journals (Sweden)

2004-05-01

Full Text Available The relatively high and rising fertility rates of Nordic countries in the late 1980s and early 1990s sparked a renewed research interest in the possible pronatalistic effects of generous family policy programs. Several studies have addressed this issue, but few have tried to model policy effects explicitly. The existing evidence so far is mainly from Sweden, where policy indicators have been incorporated in economic fertility models that also control for female wages. This paper complements previous Swedish analyses with evidence from Norway and Finland. The results corroborate earlier findings of a negative effect of female wages. There are also indications of a positive policy impact, as maternity leave extensions are estimated to raise birth rates, although mainly higher parity births and mainly in Finland.

Report of a Policy Forum: Weather, Climate, and Energy

2002-07-01

The report of a policy forum on Weather, Climate, and Energy presents findings and recommendations that, if implemented, could position the energy sector, the providers of weather and climate science and services, and energy consumers to mange more cooperatively and effectively the production, distribution, and consumption of electrical power and fossil fuels. Recent U.S. experience with a series of energy shortages encouraged the AMS Atmospheric Policy Program to join with the University of Oklahoma in the development of a forum to address the issues connected with responding to those shortages. Nearly 100 representatives from the public, private, and academic portions of the energy production sector, the meteorological community, political and corporate leaders, weather risk management analysts, and policy makers met on October 16-17, 2001 to discuss these policy issues.

How Smog Awareness Influences Public Acceptance of Congestion Charge Policies

Directory of Open Access Journals (Sweden)

Lingyi Zhou

2017-09-01

Full Text Available Although various studies have investigated public acceptance of congestion charge policies, most of them have focused on behavioral and policy-related factors, and did not consider the moderating influence that individual concern about smog and perceived smog risk may have on public acceptance. This paper takes the congestion charge policy in China, targeted at smog and traffic control, and checks how smog awareness—including smog concerns and perceived smog risks, besides behavioral and policy-related factors—might influence public acceptance of the policy. In this paper, we found both a direct and moderating causal relationship between smog awareness and public acceptance. Based on a sample of 574 valid questionnaires in Beijing and Shanghai in 2016, an ordered logistic regression modeling approach was used to delineate the causality between smog awareness and public acceptance. We found that both smog concerns, such as perceived smog risk, and willingness to pay (WTP were both directly and indirectly positively correlated with public acceptance. These findings imply that policymakers should increase policy fairness with environmental-oriented policy design and should express potential policy effectiveness of the smog controlling policy to citizens to increase their acceptance level.

2016-01-01

Along with China's rapid industrialization and urbanization, challenges in reducing pollution and CO_2 emissions are increasing. One of the major approaches to coordinate economic growth and environmental protection is to substitute coal-fired power with renewable energy. Since 2003, in order to promote wind power development, China has put in place many support policies which fall into either price policy category or non-price policy category. By using a variable intercept and mixed regression model with provincial panel data during 2001–2013, we analyzed the impacts of both categories on the increase of installed capacity in areas with different wind resources. We found that price policy and two non-price policies had positive impacts on the increase of wind power installation, price policy played a greater role than non-price policy did in promoting wind power development, and price policy was more effective in areas with poor wind resources, whilst non- price policy was more effective in areas with rich wind resources. Built on these findings, conclusions and policy recommendations are provided at the end of the paper. - Highlights: •We study the impact of price policy on China's new wind power capacity. •Four non-price policies impact on China's new wind power capacity is studied. •Price policy is more effective in wind power increase than non-price policy. •Price policy is more effective than non-price policy in wind non-rich areas. •Non-price policy is more effective than price policy in wind rich areas.

Are leftists more emotion-driven than rightists? The interactive influence of ideology and emotions on support for policies.

Pliskin, Ruthie; Bar-Tal, Daniel; Sheppes, Gal; Halperin, Eran

2014-12-01

Although emotions and ideology are important factors guiding policy support in conflict, their interactive influence remains unclear. Based on prior findings that ideological leftists' beliefs are more susceptible to change than rightists' beliefs, we tested a somewhat counterintuitive extension that leftists would be more susceptible to influence by their emotional reactions than rightists. In three laboratory studies, inducing positive and negative emotions affected Jewish-Israeli leftists', but not rightists', support for conciliatory policies toward an adversarial (Studies 1 and 3) and a non-adversarial (Study 2) outgroup. Three additional field studies showed that positive and negative emotions were related to leftists', but not rightists', policy support in positive as well as highly negative conflict-related contexts, among both Jewish (Studies 4 and 5) and Palestinian (Study 6) citizens of Israel. Across different conflicts, emotions, conflict-related contexts, and even populations, leftists' policy support changed in accordance with emotional reactions more than rightists' policy support. © 2014 by the Society for Personality and Social Psychology, Inc.

Policy recommendations for Canadian municipal greenhouse gas trading

International Nuclear Information System (INIS)

Seskus, A.

2002-01-01

The municipal policies regarding greenhouse gas (GHG) emissions trading from municipalities in developed countries outside of Canada were examined in an effort to help establish a position on municipal carbon trading in Canada. The main uncertainty regarding this new concept of GHG emissions trading is the fate of the Kyoto Protocol, when or if it will be ratified. It is premature for municipalities to have well-established polices about emissions trading because the country in which a municipality is located determines the position towards GHG emissions trading. For this study, an extensive literature search of municipal policies was conducted for both GHG trading and domestic national GHG trading. This was followed by a survey on emissions trading which was distributed to more than 350 member cities (including the United States, Europe and Australia) of the International Council for Environmental Initiatives (ICLEI) Cities for Climate Protection (CCP) Campaign. The literature search revealed that municipalities outside of Canada have not yet formulated policies to address the issue of emissions trading. Only 7 per cent of the cities felt that they were informed about emissions trading, even in Europe and Australia where domestic emissions trading is closer to becoming a reality. This paper demonstrated that it is evident that more training is needed for municipalities regarding this issue. For the very few cities that had developed a GHG trading policy, each municipal policy supported municipal participation in emissions trading under conditions that included an environmental retirement, a do-no-harm clause, or an obligation to meet voluntary commitments before excess emissions can be traded. refs., tabs., figs

Sherlon Kauffman; John Musson; Hai Dong; Lisa Kaufman; Arne Freyberger

2005-01-01

The proposed HAPPEX experiment at CEBAF employs a three cavity monitor system for high precision (1um), high bandwidth (100 kHz) position measurements. This is performed using a cavity triplet consisting of two TM110-mode cavities (one each for X and Y planes) combined with a conventional TM010-mode cavity for a phase and magnitude reference. Traditional systems have used the TM010 cavity output to directly down convert the BPM cavity signals to base band. The multi-channel HAPPEX digital receiver simultaneously I/Q samples each cavity and extracts position using a CORDIC algorithm. The hardware design consists of a RF receiver daughter board and a digital processor motherboard that resides in a VXI crate. The daughter board down converts 1.497 GHz signals from the TM010 cavity and X and Y signals from the TM110 cavities to 3 MHz and extracts the quadrature digital signals. The motherboard processes this data and computes beam intensity and X-Y positions with resolution of 1um, 100 kHz output bandwidth, and overall latency of 1us. The results are available in both the analog and digital format

Values in Health Policy – A Concept Analysis

Directory of Open Access Journals (Sweden)

Lida Shams

2016-11-01

Full Text Available Background Despite the significant role “values” play in decision-making no definition or attributes regarding the concept have been provided in health policy-making. This study aimed to clarify the defining attributes of a concept of value and its irrelevant structures in health policy-making. We anticipate our findings will help reduce the semantic ambiguities associated with the use of “values” and other concepts such as principles, criteria, attitudes, and beliefs. Methods An extensive search of literature was carried out using electronic data base and library. The overall search strategy yielded about 1540 articles and 450 additional records. Based on traditional qualitative research, studies were purposefully selected and the coding of articles continued until data saturation was reached. Accordingly, 31 articles, 2 books, and 5 other documents were selected for the review. We applied Walker and Avant’s method of concept analysis in studying the phenomenon. Definitions, applications, attributes, antecedents, and consequences of the concept of “value in health policy-making” were extracted. We also identified similarities and differences that exist between and within them. Results We identified eight major attributes of “value in health policy-making”: ideological origin, affect one’s choices, more resistant to change over time, source of motivation, ability to sacrifice one’s interest, goal-oriented nature for community, trans-situational and subjectivity. Other features pinpointed include alternatives, antecedents, and consequences. Alternative, antecedents and consequences case may have more or fewer attributes or may lack one of these attributes and at the same time have other distinctive ones. Conclusion Despite the use of the value framework, ambiguities still persist in providing definition of the concept value in health policy-making. Understanding the concept of value in health policy-making may provide extra

LHC beam dumping system Extraction channel layout and acceptance

The LHC beam dumping system must safely abort the LHC beams under all conditions, including those resulting from abnormal behaviour of machine elements or subsystems of the beam dumping system itself. The extraction channels must provide sufficient aperture both for the circulating and extracted beams, over the whole energy range and under various beam parameters. These requirements impose tight constraints on the tolerances of various extraction channel components, and also on the allowed range of beam positions in the region of these components. Operation of the beam dumping system under various fault states has been considered, and the resulting apertures calculated. After describing briefly the beam dumping system and the extraction channel geometry, the various assumptions made in the analysis are presented, before deriving tolerance limits for the relevant equipment and beam parameters.

Identifying structural barriers to an effective HIV response: using the National Composite Policy Index data to evaluate the human rights, legal and policy environment

Gruskin, Sofia; Ferguson, Laura; Alfven, Tobias; Rugg, Deborah; Peersman, Greet

2013-01-01

Introduction Attention to the negative effects of structural barriers on HIV efforts is increasing. Reviewing national legal and policy environments with attention to the international human rights commitments of states is a means of assessing and providing focus for addressing these barriers to effective HIV responses. Methods Law and policy data from the 171 countries reporting under the Declaration of Commitment from the 2001 United Nations General Assembly Special Session on HIV/AIDS were analyzed to assess attention to human rights in national legal and policy environments as relevant to the health and rights of key populations such as people who inject drugs, men who have sex with men and sex workers. Results Seventy-eight governments and civil society in 106 countries report the existence of laws and policies which present obstacles to accessing HIV services for key populations. Laws and policies which positively affect access to HIV-related services, in and of themselves constituting structural interventions, were also reported. The dissonance between laws and how this impacts the availability and use of HIV-related services deserve greater attention. Conclusions Recognition of the harms inherent in laws that constitute structural barriers to effective HIV responses and the potential positive role that a supportive legal environment can play suggests the need for legal reform to ensure an enabling regulatory framework within which HIV services can be effectively delivered and used by the populations who need them. Moving beyond laws and policies, further efforts are required to determine how to capture information on the range of structural barriers. Teasing apart the impact of different barriers, as well as the structural interventions put in place to address them, remains complicated. Capturing the impact of policy and legal interventions can ultimately support governments and civil society to ensure the human rights of key populations are protected in

Can human ecology contribute towards originating a preventive environmental policy. Following a discussion of the demands of preventive environmental policy between theory and practice, the book presents the scientific approach 'human ecology' from a social-scientific angle. Then the question of the foundation in environmentally-related ethics is dealt with. The application and realizability of human-ecological considerations are tested with reference to different sectors of politics, and positive and negative indications of the chances of realization of a preventive environmental policy are discussed.

Does climate policy lead to relocation with adverse effects for GHG emissions or not? A first assessment of the spillovers of climate policy for energy intensive industry

International Nuclear Information System (INIS)

Oikonomou, V.; Patel, M.; Worrell, E.

2004-12-01

Energy-intensive industries play a special role in climate policy. World-wide, industry is responsible for about 50% of greenhouse gas emissions. The emission intensity makes these industries an important target for climate policy. At the same time these industries are particularly vulnerable if climate policy would lead to higher energy costs, and if they would be unable to offset these increased costs. The side effects of climate policy on GHG emissions in foreign countries are typically referred to as 'spillovers'. Negative spillovers reduce the effectiveness of a climate policy, while positive spillovers increase its effectiveness. This paper provides a review of the literature on the spillover effects of climate policy for carbon intensive industries. Reviews of past trends in production location of energy-intensive industries show an increased share of non-Annex 1 countries. However, this trend is primarily driven by demand growth, and there is no empirical evidence for a role of environmental policy in these development patterns. In contrast, climate models do show a strong carbon leakage of emissions from these industries. Even though that climate policy may have a more profound impact than previous environmental policies, the results of the modelling are ambiguous. The energy and carbon intensity of energy-intensive industries is rapidly declining in most developing countries, and reducing the 'gap' between industrialized and developing countries. Still, considerable potential for emission reduction exists, both in developing and industrialized countries. Technology development is likely to deliver further reductions in energy use and CO2 emissions. Despite the potential for positive spillovers in the energy-intensive industries, none of the models used in the analysis of spillovers of climate policies has an endogenous representation of technological change for the energy-intensive industries. This underlines the need for a better understanding of

The impact of South Korea's new drug-pricing policy on market competition among off-patent drugs.

2015-01-01

A new pricing policy was introduced in Korea in April 2012 with the aim of strengthening competition among off-patent drugs by eliminating price gaps between originators and generics. Examine the effect of newly implemented pricing policy. Retrospectively examining the effects through extracting from the National Health Insurance claims data a 30-month panel dataset (January 2011-June 2013) containing consumption data in four major therapeutic classes (antihypertensives, lipid-lowering drugs, antiulcerants and antidepressants). Proxies for market competition were examined before and after the policy. The new pricing policy did not enhance competition among off-patent drugs. In fact, price dispersion significantly decreased as opposed to the expected change. Originator-to-generic utilization increased 6.12 times (p = 0.000) after the new policy. The new pricing policy made no impact on competition among off-patent drugs. Competition in the off-patent market cannot be enhanced unless both supply and demand side measures are coordinated.

Use of supercritical carbon dioxide extraction

Energy Technology Data Exchange (ETDEWEB)

Taniguchi, Masayuki (Niigata Univ., Faculty of Engineering, Niigata, (Japan))

1989-09-25

Supercritical fluid extraction is a novel diffusion and separation technique which exploits simultaneously the increase of vapor pressure and the difference of chemical affinities of fluids near the critical point. A solvent which is used as the supercritical fluid has the following features: the critical point exists in the position of relatively ease of handling, the solvent is applicable to the extraction of a physiological active substance of thermal instability. Carbon dioxide as the solvent is non-flammable, non-corrosive, non-toxic, cheap, and readily available of high purity. The results of studies on the use of supercritical carbon dioxide (SC-CO{sub 2}) as a solvent for natural products in the fermentation and food industries, were collected. SC-CO{sub 2} extraction are used in many fields, examples for the application are as follows: removal of organic solvents from antibiotics; extraction of vegetable oils contained in wheat germ oil, high quality mustard seeds, rice bran and so on; brewing of sake using rice and rice-koji; use as a non-aqueous medium for the synthesis of precursors of the Aspartame; and use in sterilization. 66 refs., 17 figs., 21 tabs.

Improving drug policy: The potential of broader democratic participation.

Science.gov (United States)

Ritter, Alison; Lancaster, Kari; Diprose, Rosalyn

2018-05-01

Policies concerned with illicit drugs vex governments. While the 'evidence-based policy' paradigm argues that governments should be informed by 'what works', in practice policy makers rarely operate this way. Moreover the evidence-based policy paradigm fails to account for democratic participatory processes, particularly how community members and people who use drugs might be included. The aim of this paper is to explore the political science thinking about democratic participation and the potential afforded in 'deliberative democracy' approaches, such as Citizens Juries and other mini-publics for improved drug policy processes. Deliberative democracy, through its focus on inclusion, equality and reasoned discussion, shows potential for drug policy reform and shifts the focus from reliance on and privileging of experts and scientific evidence. But the very nature of this kind of 'deliberation' may delimit participation, notably through its insistence on authorised modes of communication. Other forms of participation beyond reasoned deliberation aligned with the ontological view that participatory processes themselves are constitutive of subject positions and policy problems, may generate opportunities for considering how the deleterious effects of authorised modes of communication might be overcome.

To assess the effect of a policy of manual rotation on the mode of delivery of fetuses in posterior or transverse positions at full dilatation. This was a prospective study to compare two policies of management for posterior and transverse positions in two different hospitals (Hospital 1: no manual rotation and Hospital 2: manual rotation). We used univariable and multivariable analyses to study the association between the management policy for posterior and transverse positions at full dilatation in these hospitals and maternal and neonatal outcomes. The principal end point was operative delivery (ie, cesarean or instrumental vaginal delivery). All factors associated with the risk of operative delivery in the univariable analysis (Pmanual rotation was independently associated with a reduction in operative deliveries. The rate of posterior or transverse positions at full dilatation was 15.9% (n=111) in Hospital 1 and 15.3% (n=220) in Hospital 2 (P=.75). Of the 172 attempts of manual rotation in Hospital 2, 155 (90.1%) were successful. The rate of operative delivery was significantly lower in Hospital 2, which performed manual rotations (23.2% compared with 38.7% in Hospital 1, adjusted odds ratio [OR] 0.52, 95% confidence interval [CI] 0.28-0.95). After multivariable analysis, manual rotation remained significantly associated with a reduction in the risk of operative delivery (adjusted OR 0.45, 95% CI 0.25-0.85). Five-minute Apgar score and arterial pH at birth were similar in the two hospitals. For fetuses in posterior or transverse positions at full dilatation, a strategy of manual rotation is associated with a reduction in the rate of operative delivery. III.

Comparative analysis of Canadian multiculturalism policy and the multiculturalism policies of other countries

Full Text Available Multiculturalism is an increasingly common characteristic of contemporary societies. In culturally diverse social contexts, virtually every person experiences intercultural contact on a daily basis. It is essential to understand that there must be both cultural diversity and equity in social participation for true multiculturalism to exist in these settings. Beyond its core definition, it is clear that multiculturalism is a complex concept encompassing many dimensions and meanings. First, the term is understood to describe a demographic fact, indicating the existence of cultural diversity in a society. Second, multiculturalism refers to the policies and programs that are in place to manage intercultural relations and acculturation. Third, multiculturalism refers to psychological phenomena, including individual attitudes and ideologies that accept or reject the demographic, civic and policy features of multiculturalism. This chapter considers Canadian multiculturalism policy, examining how the multiple meanings of multiculturalism vary around the world. Within this framework, I highlight the psychological processes and outcomes of multiculturalism, particularly in connection with acculturation, adaptation and intercultural relations and consider whether these processes and outcomes differ for dominant and non-dominant groups. I suggest some ways in which to enhance the positive outcomes of intercultural contact and the resultant acculturation outcomes. Finally, this chapter sets the stage for the presentation of the other chapters in this volume. It elaborates three hypotheses derived from Canadian multiculturalism policy: the multiculturalism, integration and contact hypotheses.

Capital flight and the uncertainty of government policies

Hermes, C.L.M.; Lensink, B.W.

This paper shows that policy uncertainty, measured by the uncertainty of budget deficits, tart payments, government consumption and the inflation rate, has a statistically significant positive impact on capital flight. This result remains robust after having applied stability tests. (C) 2001

REGULATION AND ENFORCEMENT OF COMPETITION POLICY

Full Text Available Competition policy starts by shaping a legislative framework. This is aimed to establish boundaries for conducting competition and also sets limits of licit and illicit demarcation, for competitive and anticompetitive practices. The Romanian Competition Law has a divalent approach and it aims to provide specific behavioral conditions in order to stimulate and protect free-market competition, with the ultimate goal of developing a balanced, efficient and competitive economy. Our country’s Competition policy is based on punishing the behavior. There are three such types of anti-competitive behavior, namely: agreements between undertakings, abuse of dominant position and mergers and other concentrations between undertakings. Recent Practice proved that this “enforcement-conduct-punishment” structure is not necessary the best way to address competition and it is high time for authorities to switch both regulation and enforcement of competition from the “classical perspective” towards concepts like “competition advocacy” and “soft power” and give competition policy a new, reshaped face.

Obstacles in the climate policy arena

Implementing climate policy is not a straightforward matter. International negotiations during the recent climate conference in The Hague ended in disagreement. With the present position of the United States chances to reach an agreement are even slimmer than ever. One of the obstacles is to what extent trade in emission rights should be allowed. Economically speaking, there are strong arguments for allowing as much flexibility as possible. Ironically, our analysis shows that the party favouring restrictions on emissions trade, the European Union, suffers most from curtailing flexibility. Another obstacle which comes up when addressing more ambitious goals in climate policy is the involvement of developing countries. A treaty should aim at emissions reductions in developing countries as well. If the potentially serious consequences of the greenhouse effect are to be avoided, that is even essential. To induce these reductions, the developed countries could consider to compensate the developing countries. For industrialised countries compensation has the effect to raise the costs of climate policy considerably

Micelle formation during extraction of alkali elements from strongly alkaline mediums

Extraction of potassium, rubidium and cesium by phenol reagents in hydrocarbon solvents from strongly alkakine solutions was considered. Tendency of prepared alkali metal phenolates to form micelles in aqueous and organic phases was revealed. Phenolates tendency to form micelles is dictated mainly by the size and position of hydrocarbon substituent in molecule. It is shown that when micelles form in organic phase, alkali elements can be extracted both according to cation-exchange mechanism and according to micellar one. It is noted that alkai element extraction from strongly alkaline media requires the correct choice of extractant: alkali metal phenolate shouldn't form micelles in aqueous solution. n-Alkyl- and arylphenoldisulfides and polysulfides are most preferable for solvent extraction among considered phenol derivatives

The Growth and Stabilization Properties of Fiscal Policy in Malaysia

This paper examines the size of the fiscal multiplier values generated in Malaysia. The results show that a government spending shock leads to broad positive economic effects. Although, the effectiveness of fiscal policy alters across macroeconomic states. The estimates show that since the Asian financial crisis the medium- and long-run effect of fiscal policy spending has declined. Some of this is down to greater credit availability and less investment spending.

Energy efficieny policy and carbon pricing

Ryan, Lisa; Moarif, Sara; Levina, Ellina; Baron, Richard

The main message of this paper is that while carbon pricing is a prerequisite for least-cost carbon mitigation strategies, carbon pricing is not enough to overcome all the barriers to cost-effective energy efficiency actions. Energy efficiency policy should be designed carefully for each sector to ensure optimal outcomes for a combination of economic, social and climate change goals. This paper aims to examine the justification for specific energy efficiency policies in economies with carbon pricing in place. The paper begins with an inventory of existing market failures that attempt to explain the limited uptake of energy efficiency. These market failures are investigated to see which can be overcome by carbon pricing in two subsectors -- electricity use in residential appliances and heating energy use in buildings. This analysis finds that carbon pricing addresses energy efficiency market failures such as externalities and imperfect energy markets. However, several market and behavioural failures in the two subsectors are identified that appear not to be addressed by carbon pricing. These include: imperfect information; principal-agent problems; and behavioural failures. In this analysis, the policies that address these market failures are identified as complementary to carbon pricing and their level of interaction with carbon pricing policies is relatively positive. These policies should be implemented when they can improve energy efficiency effectively and efficiently (and achieve other national goals such as improving socio-economic efficiency).
