    The mechanism by which nitrite inhibits outgrowing spores of bacillus cereus T was examined by using techniques developed earlier for nitrite analogs. The morphological stage of inhibition, cooperativity effects, effect of pH on inhibition, kinetics of protection against tritiated iodoacetate incorporation into membrane sulfhydryl groups, and protection against the bacteriocidal effect of carboxymethylation of iodoacetate indicate that nitrite acts as a membrane-directed sulfhydryl agent. The mechanism by which nitrite modifies the chemical reactivity of the sulfhyrdyl group could be either direct covalent modification or inactivation through communication with another modified membrane component. Profiles of pH effects suggest that the active agent is the protonated form of nitrite. The nitrite concentrations which modify membrane sulfhydryl activity coincide with those which have a bacteriostatic effect. These results are consistent with membrane sulfhydryl modification as a component of the mechanism of nitrite-induced bacteriostasis in this aerobic sporeformer

    Full Text Available Summary. One of the major causes of decline in the quality of granulated sugar is bacterial contamination of sugar beet. This is due to the fact that the beet-sugar industry is a good object for the development of different groups of microorganisms. The main sources of infection of products of sugar manufacture can be soil, water, air, packaging, packaging materials, vehicles, clothing, equipment. The higher the beet contamination with the microorganisms, the more they decompose sucrose and secrete metabolic byproducts. In this regard, there is a need to reduce the negative impact of various groups of microorganisms and to minimize the loss of sucrose from decomposition. In accordance with the problem given the studies to determine the bacteriostatic properties of chlorinated compounds for sugar production were carried out. We used the cultivated fluid colonized with a pure culture of Leuconostoc mesenteroides and reagent treated as an object of study. In the experiments, we determined the accumulation of biomass of L. mesenteroides with nephelometric method by measuring the optical density of bacterial suspension. It was found out that after 24 hours of bacterial culturing the level of optical density in the control and active acidity were considerably higher compared with the sample treated with germicide. The number of microorganisms in the nutrient medium was determined by Vinogradsky-Shulgina-Brid’s. According to the study in the control is 1,7*10^16, in experiment with the introduction of the chlorinated compound it is 5,8*10^14. The experimental results show that the investigated chlorinated compound has bacteriostatic action against grampositive cocci saprophytic of L. mesenteroides and can be recommended for use in a sugar beet production.

    Sanitary and hygienic properties of air saturated with volatile organic compounds of plants (VOC) have a fundamental importance for the biosphere. In particular, they make such a feature as the freshness of the air. The energy contained in VOC and made by Earth vegetation can be compared with the energy of lightning discharges in the atmosphere during the year [1]. The influence of natural environment on the dynamics of VOC developed by plants is also of current interest and is, in particular, important for resort study because VOC produced by the vegetation of the resort regions can be seen as a self-contained resort resource [2]. Dynamics of VOC evolution by Crimean pine (Pinus Pallasiana D.Don.) that is the forest forming breed of the resort region Caucasus Mineral Waters (Russia) has been studied by a microbiological method [1]. Dynamics of bacteriostatics was qualified by the extent of oppression of the VOC test- culture (Staphylococcus aureus 209p) of the pine in % in comparison with control. The needles for the experience were selected at noon in the middle of the summer. At the time of the needle selection meteorological indicators were fixed. As the result of the researches we got an empirical equation of dynamics of VOC bacteriostatics of the Crimean pine under the influence of total solar radiation (kW/m2) and relative air humidity (%). The coefficient of the multiple correlation of the VOC bacteriostatics of the Crimean pine, total solar radiation and relative air humidity makes: R=0,83 at the importance of F=7,53>F0 05=3,49. The coefficient of the multiple determination is R2=0,69. The equation is: y = - 35,1020 + 1,7193x + 175,6638p- 0,0181x2 + 0,6054 (xp) - 191,1319p2, where Y - is bacteriostatics (%); x - is relative humidity (%); p - is total solar radiation (kW/m2). The fixed parameters of the equation are: air humidity - 90-30%; total solar radiation - 0.20-1.0 kW/m2; bacteriostatics - 0-61%. The obtained results can be used in the resort study

    In this study, the bacteriostatic effect of Piper betle and Psidium guajava extracts on selected early dental plaque bacteria was investigated based on changes in the doubling time (g) and specific growth rates (micro). Streptococcus sanguinis, Streptococcus mitis and Actinomyces sp. were cultured in Brain Heart Infusion (BHI) in the presence and absence of the extracts. The growth of bacteria was monitored periodically every 15 min over a period of 9 h to allow for a complete growth cycle. Growth profiles of the bacteria in the presence of the extracts were compared to those in the absence and deviation in the g and micro were determined and analyzed. It was found that the g and mu were affected by both extracts. At 4 mg mL(-1) of P. betle the g-values for S. sanguinis and S. mitis were increased by 12.0- and 10.4-fold, respectively (p betle and P. guajava extracts have bacteriostatic effect on the plaque bacteria by creating a stressed environment that had suppressed the growth and propagation of the cells. Within the context of the dental plaque, this would ensure the attainment of thin and healthy plaque. Thus, decoctions of these plants would be suitable if used in the control of dental plaque.

    Quercetin, a ubiquitous flavonoid, is known to have antibacterial effects. The purpose of this study was to investigate the effect of quercetin on cecal microbiota of Arbor Acre (AA) broiler chickens in vivo and the bacteriostatic effect and antibacterial mechanism of quercetin in vitro. In vivo, 480 AA broilers (1 day old) were randomly allotted to four treatments (negative control and 0.2, 0.4, or 0.6 g of quercetin per kg of diet) for 42 days. Cecal microbial population and distribution were measured at the end of the experiment. The cecal microflora in these broilers included Proteobacteria, Fimicutes, Bacteroidetes, and Deferribacteres. Compared with the negative control, quercetin significantly decreased the copies of Pseudomonas aeruginosa ( P 0.05). These results suggest that quercetin has potential as an alternative antibiotic feed additive in animal production.

    The stability of chlorfenvinphos acaricide was studied in 50 L model dip tanks using a mixture of 14 C-labelled and unlabelled chlorfenvinphos with or without recharge. Calcium superphosphate fertilizer was used as buffer and to reduce the pH to below 5, while copper sulfate was used as a bacteriostat. In addition 50 g of sediment from around the dip tank was added to the vats and contents of vats were made up to 50 L using the water available at chalimbana NCSR farm. The buffer, by itself as well as in combination with copper sulfate stabilized chiorfenvinphos in the suspension. Binding with the sediment was a key factor in the reduction of chlorfenvinphos level, which was significantly reduced in all vats that contained sediments. Most of the acaricide bound to the sediment was not extractable. The pH in vats was maintained at 4.8 - 5.0 by the addition of superphosphate fertilizer, which reduced the degradation of chlorfenvinphos. Copper sulfate had no effect on the pH of the suspension and the vats treated with the bacteriostat had the lowest levels of chlorfenvinphos. TLC analysis also showed that acaricide breakdown was greater in non-buffered than in buffered vats. A metabolite, 2,4-dichloroacetophenone, was detected, although at a low level. A study of the leaching potential of chlorfenvinphos in soil columns showed that only 3% of the applied acaricide percolated through the 30 cm length of the column, while most of it remained soil-bound. A calorimetric method for measuring the concentration of chlorfenvinphos in dips was evaluated. The method is based on the reaction of the acaricide with 4-(4-nitrobenzyl) pyridine and subsequent measurement of the intensity of the colour formed with tetraethylene pentamine. The measurement was relatively accurate. (author)

    Human milk possesses bacteriostatic properties, largely due to the presence of immunological proteins. Heat treatments such as Holder pasteurization reduce the concentration of immunological proteins in human milk and consequently increase the bacterial growth rate. This study investigated the bacterial growth rate and the immunological protein concentration of ultraviolet (UV-C) irradiated, Holder pasteurized and untreated human milk. Samples (n=10) of untreated, Holder pasteurized and UV-C irradiated human milk were inoculated with E. coli and S. aureus and the growth rate over 2 hours incubation time at 37°C was observed. Additionally, the concentration of sIgA, lactoferrin and lysozyme of untreated and treated human milk was analyzed. The bacterial growth rate of untreated and UV-C irradiated human milk was not significantly different. The bacterial growth rate of Holder pasteurized human milk was double compared to untreated human milk (ppasteurization, resulting in bacteriostatic properties similar to those of untreated human milk.

    Carbon dots with heteroatom co-doping associated with consummate luminescence features are of acute interest in diverse applications such as biomolecule markers, chemical sensing, photovoltaic, and trace element detection. Herein, we demonstrate a straightforward, highly efficient hydrothermal dehydration technique to synthesize zinc and nitrogen co-doped multifunctional carbon dots (N, Zn-CDs) with superior quantum yield (50.8%). The luminescence property of the carbon dots can be tuned by regulating precursor ratio and surface oxidation states in the carbon dots. A unique attribution of the as-prepared carbon dots is the high monodispersity and robust excitation-independent emission behavior that is stable in enormously reactive environment and over a wide range of pH. These N, Zn-CDs unveils captivating bacteriostatic activity against gram-negative bacteria Escherichia coli. Furthermore, the excellent luminescence properties of these carbon dots were applied as a platform of sensitive biosensor for the detection of hydrogen peroxide. Under optimized conditions, these N, Zn-CDs reveals high sensitivity over a broad range of concentrations with an ultra-low limit of detection (LOD) indicating their pronounced prospective as a fluorescent probe for chemical sensing. Overall, the experimental outcomes propose that these zero-dimensional nano-dots could be developed as bacteriostatic agents to control and prevent the persistence and spreading of bacterial infections and as a fluorescent probe for hydrogen peroxide detection.

    In the present work a detailed study of new bacteriostatic copolymers with quaternized ammonium groups introduced in the polymer chain through covalent attachment or electrostatic interaction, was performed. Different copolymers have been considered since beside the active species, the hydrophobic/hydrophilic nature of the co-monomer was also evaluated in the case of covalently attached bacteriostatic groups, aiming at achieving permanent antibacterial activity. Homopolymers with quaternized ammonium/phosphonium groups were also tested for comparison reasons. The antimicrobial activity of the synthesized polymers after 3 and 24 h of exposure at 4 and 22 °C was investigated on cultures of Gram-negative (P. aeruginosa, E. coli) and Gram-positive (S. aureus, E. faecalis) bacteria. It was found that the combination of the hydrophilic monomer acrylic acid (AA), at low contents, with the covalently attached bacteriostatic group vinyl benzyl dimethylhexadecylammonium chloride (VBCHAM) in the copolymer P(AA-co-VBCHAM88), resulted in a high bacteriostatic activity against P. aeruginosa and E. faecalis (6 log reduction in certain cases). Moreover, the combination of covalently attached VBCHAM units with electrostatically bound cetyltrimethylammonium 4-styrene sulfonate (SSAmC16) units in the P(SSAmC16-co-VBCHAMx) copolymers led to efficient antimicrobial materials, especially against Gram-positive bacteria, where a log reduction between 4.9 and 6.2 was verified. These materials remain remarkably efficient even when they are incorporated in polysulfone membranes.

  18. Inhibition of Erwinia chrysanthemi growth to different concentrations of folic acid: possible use of folic acid as bacteriostatic agent and fortifying of Solanum tuberosum potato

    2017-05-01

    Full Text Available Introduction:The enterobacteria of the Erwinia spp genus produce disease in potatoes, which is a tuber of mass consumption. The regulation of DNA methylation can regulate the proliferation of Erwinia in such a way that the concentrations of folic acid may have an effect on the microorganism pathogenic ability. On the other hand, the folic acid prevents the appearance of neural tube defects in humans. Objective: To evaluate folic acid as a bacteriostatic agent of Erwinia and, at the same time, as part of the fortification of mass consumption food such as the potatoes. Materials and methods: The biochemical characterization of the Erwinia chrysanthemi was carried out and its growth compared to different concentrations of folic acid was studied. Results: When increasing the concentrations of the vitamin from 0.3 µg/L up to 6.8 µg/L, the bacterial growth of Erwinia chrysanthemi is inhibited. The vitamin inhibits the growth in cultivation of Erwinia chrysanthemi and acts as a bacteriostatic agent. This aspect is of great importance given that, theoretically, if potatoes were fortified with micro-nutrient, this would act against the infectious agent and, at the same time, contribute to the adequate intake of the vitamin in the general population.

    Full Text Available Adjunctive vitamin D treatment for pulmonary tuberculosis enhances resolution of inflammation but has modest effects on bacterial clearance. Sodium 4-phenylbutyrate (PBA is in clinical use for a range of conditions and has been shown to synergise with vitamin D metabolites to upregulate cathelicidin antimicrobial peptide (CAMP expression. We investigated whether clinically attainable plasma concentrations of PBA (0.4-4 mM directly affect Mycobacterium tuberculosis (Mtb growth and human macrophage and PBMC response to infection. We also tested the ability of PBA to enhance the immunomodulatory actions of the vitamin D metabolite 25(OHD3 during infection and synergistically inhibit intracellular Mtb growth. PBA inhibited Mtb growth in broth with an MIC99 of 1 mM, which was reduced to 0.25 mM by lowering pH. During human macrophage infection, PBA treatment restricted Mtb uptake, phagocytic receptor expression and intracellular growth in a dose-dependent manner. PBA independently regulated CCL chemokine secretion and induced expression of the antimicrobial LTF (lactoferrin, the anti-inflammatory PROC (protein C and multiple genes within the NLRP3 inflammasome pathway. PBA co-treatment with 25(OHD3 synergistically modulated expression of numerous vitamin D-response genes, including CAMP, CYP24A1, CXCL10 and IL-37. This synergistic effect was dependent on MAPK signalling, while the effect of PBA on LTF, PROC and NLRP3 was MAPK-independent. During PBA and 25(OHD3 co-treatment of human macrophages, in the absence of exogenous proteinase 3 (PR3 to activate cathelicidin, Mtb growth restriction was dominated by the effect of PBA, while the addition of PR3 enhanced growth restriction by 25(OHD3 and PBA co-treatment. This suggests that PBA augments vitamin D-mediated cathelicidin-dependent Mtb growth restriction by human macrophages and independently induces antimicrobial and anti-inflammatory action. Therefore through both host-directed and bacterial

    Pseudotuberculosis and bubonic plague are acute infectious diseases caused by the bacteria Yersinia pseudotuberculosis and Yersinia pestis. These diseases are treated, in particular, with trimethoprim and its modified analogues. However, uridine phosphorylases (pyrimidine nucleoside phosphorylases) that are present in bacterial cells neutralize the action of trimethoprim and its modified analogues on the cells. In order to reveal the character of the interaction of the drug with bacterial uridine phosphorylase, the atomic structure of the unligated molecule of uridine-specific pyrimidine nucleoside phosphorylase from Yersinia pseudotuberculosis (YptUPh) was determined by X-ray diffraction at 1.7 Å resolution with high reliability (R{sub work} = 16.2, R{sub free} = 19.4%; r.m.s.d. of bond lengths and bond angles are 0.006 Å and 1.005°, respectively; DPI = 0.107 Å). The atoms of the amino acid residues of the functionally important secondary-structure elements—the loop L9 and the helix H8—of the enzyme YptUPh were located. The three-dimensional structure of the complex of YptUPh with modified trimethoprim—referred to as 53I—was determined by the computer simulation. It was shown that 53I is a pseudosubstrate of uridine phosphorylases, and its pyrimidine-2,4-diamine group is located in the phosphate-binding site of the enzyme YptUPh.

These diseases are treated, in particular, with trimethoprim and its modified analogues. However, uridine phosphorylases (pyrimidine nucleoside phosphorylases) that are present in bacterial cells neutralize the action of trimethoprim and its modified analogues on the cells. In order to reveal the character of the interaction of the drug with bacterial uridine phosphorylase, the atomic structure of the unligated molecule of uridine-specific pyrimidine nucleoside phosphorylase from Yersinia pseudotuberculosis ( YptUPh) was determined by X-ray diffraction at 1.7 Å resolution with high reliability ( R work = 16.2, R free = 19.4%; r.m.s.d. of bond lengths and bond angles are 0.006 Å and 1.005°, respectively; DPI = 0.107 Å). The atoms of the amino acid residues of the functionally important secondary-structure elements—the loop L9 and the helix H8—of the enzyme YptUPh were located. The three-dimensional structure of the complex of YptUPh with modified trimethoprim—referred to as 53I—was determined by the computer simulation. It was shown that 53I is a pseudosubstrate of uridine phosphorylases, and its pyrimidine-2,4-diamine group is located in the phosphate-binding site of the enzyme YptUPh.

    This study investigates the antibacterial mechanism of action of electrospun chitosan-based nanofibers (CNFs), against Escherichia coli , Salmonella enterica serovar Typhimurium, Staphylococcus aureus and Listeria innocua , bacteria frequently involved in food contamination and spoilage. CNFs were prepared by electrospinning of chitosan and poly(ethylene oxide) (PEO) blends. The in vitro antibacterial activity of CNFs was evaluated and the susceptibility/resistance of the selected bacteria toward CNFs was examined. Strain susceptibility was evaluated in terms of bacterial type, cell surface hydrophobicity, and charge density, as well as pathogenicity. The efficiency of CNFs on the preservation and shelf life extension of fresh red meat was also assessed. Our results demonstrate that the antibacterial action of CNFs depends on the protonation of their amino groups, regardless of bacterial type and their mechanism of action was bactericidal rather than bacteriostatic. Results also indicate that bacterial susceptibility was not Gram-dependent but strain-dependent, with non-virulent bacteria showing higher susceptibility at a reduction rate of 99.9%. The susceptibility order was: E. coli > L. innocua > S. aureus > S. Typhimurium. Finally, an extension of one week of the shelf life of fresh meat was successfully achieved. These results are promising and of great utility for the potential use of CNFs as bioactive food packaging materials in the food industry, and more specifically in meat quality preservation.

    Inhibiting action of A, B and M-X compositions against hydrosulfide corrosion of carbon steel, hydrogen diffusion through the steel membrane has been studied along with their bactericidal effect with respect to sulfate-reducing bacteria of Desulfomicrobium type. Bactericidal properties of the compositions have been studied in the Postgate medium. Corrosion tests have been made in the NACE medium saturated by hydrogen sulfide and carbon dioxide separately and together by methods of gravimetrical measurements and linear polarization resistance (LRP). Potentiodynamic polarization and electrochemical diffusion method have been used. Steel protection is determined in the inhibited solutions by combined action of corrosion products film and inhibitor. Presence of sulfate-reducing bacteria in medium increases hydrogen diffusion flux through the steel membrane by 2-3 times and essentially stimulates effect of the inhibitors. The inhibiting compositions decrease quantity of sulfate-reducing bacteria (SRB) by 95-98%. The obtained results testify about predominately bacteriostatic action of the inhibiting compositions, which has influence on the enzymatic systems of SRB cells responsible directly for the sulfate reduction because of substantially decreasing the biogenic hydrogen sulfide concentration in the system. © 2013 Elsevier B.V.

    Caffeine is an alkaloid (purine derivative) that contains flavonoids, where as aspirin, natural component of mammalian tissue ( acetylsalicylic acid) is one of the most commonly used non steroidal anti - inflammatory , and it is a necessary factor in the utilization of long - chain fatty acids to produce energy. Furthermore, it has been shown to protect cells from per oxidative stress. Th e objective of the present study is to evaluate the efficacy of caffeine (1,3,7 - trimethyl xanthine) 80 mg/kg b.wt. a nd aspirin ( acetylsalicylic acid) in the amelioration of the physiological and histological changes in stomach and intestine of rats exposed to gamma irradiation . Male albino rats were divided into 8 groups. 1 - Control group: rats not subject to any treatment, 2 - Caffeine group: rats received caffeine ( 80 ml/Kg body weight )via intraperitoneal injection for 21 days, 3 - Aspirin group: rats received aspirin (150 mg / kg body) via intraperitoneal injection for 21 days , 4 - Caffeine + Aspirin group: rats received caffeine a nd aspirin treatment, 5 - Radiation groups: rats were whole body gamma irradiated at 8 Gy , 6 - Caffeine + Radiation group: rats received caffeine for 21 days before whole body gamma irradiation at 8 Gy, 7 - Aspirin + Radiation group: rats received aspirin during 21 days before w hole body gamma irradiation , 8 - Caffeine + Aspirin + Radiation group: rats received caffeine parallel to aspirin for 21 days before whole body gamma irradiation. Animals were sacrificed 24 hrs post irradiation. The results demonstrated that rats exposed to whole body gamma irradiation showed a significant increase in alanine amino transferase (AL ) , aspartate amino transferase ( AST), and alkaline phosphatase (ALP) activities, and a significant decrease in total protein indicating liver injury. A significant increase in urea, creatinine, Na + ,and K + were recorded indicating kidney damage. Alteration of liver and kidney functions was accompanied by a significant increase in the content of thiobarbituric acid reactive substances (TBARS) associated with a significant decrease in glutathione (GSH) content, superoxide dismutase (SOD), and catalase (CAT) activities indicating oxidative stress. In addition, radiation caused inflammatory, fibrotic and cellular damage to the intestine and stomach. A demonstration of caffeine and aspirin resulted in significant improvement in hepatic and renal functions associated with reduction in oxidative stress and amelioration of the histological changes caused by gamma irradiation. It could be concluded that the antioxidant properties of caffeine and aspirin might modulate γ-radiation-induced oxidative stress and histological disorders

  12. Tetracyclines function as dual-action light-activated antibiotics.

    Directory of Open Access Journals (Sweden)

    Ya He

    Full Text Available Antimicrobial photodynamic inactivation (aPDI employs photosensitizing dyes activated by visible light to produce reactive oxygen species. aPDI is independent of the antibiotic resistance status of the target cells, and is thought unlikely to produce resistance itself. Among many PS that have been investigated, tetracyclines occupy a unique niche. They are potentially dual-action compounds that can both kill bacteria under illumination, and prevent bacterial regrowth by inhibiting ribosomes. Tetracycline antibiotics are regarded as bacteriostatic rather than bactericidal. Doxycycline (DOTC is excited best by UVA light (365 nm while demeclocycline (DMCT can be efficiently activated by blue light (415 nm as well as UVA. Both compounds were able to eradicate Gram-positive (methicillin-resistant Staphylococcus aureus and Gram-negative (Escherichia coli bacteria (>6 log(10 steps of killing at concentrations (10-50μM and fluences (10-20J/cm2. In contrast to methylene blue, MB plus red light, tetracyclines photoinactivated bacteria in rich growth medium. When ~3 logs of bacteria were killed with DMCT/DOTC+light and the surviving cells were added to growth medium, further bacterial killing was observed, while the same experiment with MB allowed complete regrowth. MIC studies were carried out either in the dark or exposed to 0.5mW/cm2 blue light. Up to three extra steps (8-fold increased antibiotic activity was found with light compared to dark, with MRSA and tetracycline-resistant strains of E. coli. Tetracyclines can accumulate in bacterial ribosomes, where they could be photoactivated with blue/UVA light producing microbial killing via ROS generation.

  13. Impulsive action and motivation.

    Science.gov (United States)

    Frijda, Nico H

    2010-07-01

    This paper explores the way in which emotions are causal determinants of action. It argues that emotional events, as appraised by the individual, elicit changes in motive states (called states of action readiness), which in turn may (or may not) cause action. Actions can be elicited automatically, without prior intention (called impulsive actions), or intentionally. Impulsive actions reflect the simplest and biologically most general form in which emotions can cause action, since they require no reflection, no foresight, and no planning. Impulsive actions are determined conjointly by the nature of action readiness, the affordances perceived in the eliciting event as appraised, and the individual's action repertoire. Those actions from one's repertoire are performed that both match the perceived affordances and the aim of the state of action readiness. Copyright © 2010 Elsevier B.V. All rights reserved.

    In this paper we investigate the use of action systems with differential actions in the specifcation of hybrid systems. As the main contribution we generalize the definition of a differential action, allowing the use of arbitrary relations over model variables and their time......-derivatives in modelling continuous-time dynamics. The generalized differential action has an intuitively appealing predicate transformer semantics, which we show to be both conjunctive and monotonic. In addition, we show that differential actions blend smoothly with conventional actions in action systems, even under...... parallel composition. Moreover, as the strength of the action system formalism is the support for stepwise development by refinement, we investigate refinement involving a differential action. We show that, due to the predicate transformer semantics, standard action refinement techniques apply also...

    Object proposals have contributed significantly to recent advances in object understanding in images. Inspired by the success of this approach, we introduce Deep Action Proposals (DAPs), an effective and efficient algorithm for generating temporal action proposals from long videos. We show how to take advantage of the vast capacity of deep learning models and memory cells to retrieve from untrimmed videos temporal segments, which are likely to contain actions. A comprehensive evaluation indicates that our approach outperforms previous work on a large scale action benchmark, runs at 134 FPS making it practical for large-scale scenarios, and exhibits an appealing ability to generalize, i.e. to retrieve good quality temporal proposals of actions unseen in training.

    We are surrounded by data, numerical, categorical and otherwise, which must to be analyzed and processed to convert it into information that instructs, answers or aids understanding and decision making. Data analysts in many disciplines such as business, education or medicine, are frequently asked to analyze new data sets which are often composed of numerous tables possessing different properties. They try to find completely new correlations between attributes and show new possibilities for users.   Action rules mining discusses some of data mining and knowledge discovery principles and then describe representative concepts, methods and algorithms connected with action. The author introduces the formal definition of action rule, notion of a simple association action rule and a representative action rule, the cost of association action rule, and gives a strategy how to construct simple association action rules of a lowest cost.

The weakest liberal precondition is chosen, because it is not always desirable that steps corresponding to differential...... actions shall terminate. It is shown that the proposed differential action has a semantics which corresponds to a discrete approximation when the discrete step size goes to zero.

    We present an approach to localize generic actions in egocentric videos, called temporal action proposals (TAPs), for accelerating the action recognition step. An egocentric TAP refers to a sequence of frames that may contain a generic action performed by the wearer of a head-mounted camera, e.g., taking a knife, spreading jam, pouring milk, or cutting carrots. Inspired by object proposals, this paper aims at generating a small number of TAPs, thereby replacing the popular sliding window strategy, for localizing all action events in the input video. To this end, we first propose to temporally segment the input video into action atoms, which are the smallest units that may contain an action. We then apply a hierarchical clustering algorithm with several egocentric cues to generate TAPs. Finally, we propose two actionness networks to score the likelihood of each TAP containing an action. The top ranked candidates are returned as output TAPs. Experimental results show that the proposed TAP detection framework performs significantly better than relevant approaches for egocentric action detection.

  10. PTTSA Action Plan Report

    1991-02-01

    The Pre-Tiger Team Self-Assessment (PTTSA) Report identified findings with respect to the way Sandia National Laboratories (SNL), Albuquerque, (including Tonopah Test Range (TTR) and Kauai Test Facility (KTF)) conducts its environment, safety, and health (ES ampersand H) activities. It presented Action Plan Requirements (APR) addressing these findings. The purpose of this PTTSA Action Plan Report is to assist in managing these action plan requirements by collecting, prioritizing, and estimating required resources. The specific objectives addressed by this report include: collection of requirements for the resolution of the findings presented in the PTTSA Report; consolidation of proposed Action Plan Requirements into logical Action Plan groupings for efficiency of resolution; categorization of Action Plans according to severity of the hazards represented by the findings; provision of a basis for long-range planning and issues management; documentation of the status of the proposed corrective actions; establishment of traceability of the corrective action to the original problem or issue; and integration of these plans into the existing ES ampersand H structure. The Action Plans in this report are an intermediate step between the identification of a problem or a finding in the PTTSA Report and the execution of the solution. They consist of requirements for solution, proposed actions, and an estimate of the time and (where applicable) resources required to develop the solution. This report is an input to the process of planning, resource commitment, development, testing, implementation, and maintenance of problem resolution. 2 figs

    Full Text Available Action Franęaise in HistoriographyFrench radical right movement, Action Franęaise belongs to those political phe- nomenon in history which are differently interpreted by historiography. Principally we have eight interpretations. First ofthem is Action Franęaise own image and identity as royalist and anti-liberal "party of order”. One of the most important historical interpretation of this movement is French historian Rene Remond’s one. In his Les Droites aujourdhui Remond argued that Action Franęaise was model example of anti-liberal Right in France and in Europe of the first half of the XX century. The most popular interpretation of Action Franęaise are two: (1 Action Franęaise as an incarnation of conservative revolution (Carl Schmitt and (2 as the ideology of "integral nationalism” (Hans Konh, Carlton Hayes. Very original concept was developed by well known German historian Ernst Nolte, who considered Action Franęaise as pro- to-fascistmovement. British thinker Isaiah Berlin and Israeli historian Zeev Sternhell interpreted Action Franęaise as revolution of "anti-Enlightment” (les anti-Lumieres. Polish philosopher Stanisław Brzozowski argued that Action Franęaise was a con- seąuence of conflict between romanticism and positivism and was sure that Action Franęaise inherited much from positivistphilosophy. Non less controversial problem is forthehistorians the excommunication of Action Franęaise by Pope Pius XI in 1926. To our days there are many opposite attempts to reconstruct of this event and its origins. For many historians Pius XI tried to defend the doctrine of the Church which seemed to him intoxicated by the "nationalist and racialist heresy”. For some other writers the Vatican policy was under German influence and this caused papai action. In 1939 another Pope Pius XII decided to abolish the condemnation from 1926.

    To investigate the mode of action of vanillin, the principle flavour component of vanilla, with regard to its antimicrobial activity against Escherichia coli, Lactobacillus plantarum and Listeria innocua. In laboratory media, MICs of 15, 75 and 35 mmol l(-1) vanillin were established for E. coli, Lact. plantarum and L. innocua, respectively. The observed inhibition was found to be bacteriostatic. Exposure to 10-40 mmol l(-1) vanillin inhibited respiration of E. coli and L. innocua. Addition of 50-70 mmol l(-1) vanillin to bacterial cell suspensions of the three organisms led to an increase in the uptake of the nucleic acid stain propidium iodide; however a significant proportion of cells still remained unstained indicating their cytoplasmic membranes were largely intact. Exposure to 50 mmol l(-1) vanillin completely dissipated potassium ion gradients in cultures of Lact. plantarum within 40 min, while partial potassium gradients remained in cultures of E. coli and L. innocua. Furthermore, the addition of 100 mmol l(-1) vanillin to cultures of Lact. plantarum resulted in the loss of pH homeostasis. However, intracellular ATP pools were largely unaffected in E. coli and L. innocua cultures upon exposure to 50 mmol l(-1) vanillin, while ATP production was stimulated in Lact. plantarum cultures. In contrast to the more potent activity of carvacrol, a well studied phenolic flavour compound, the extent of membrane damage caused by vanillin is less severe. Vanillin is primarily a membrane-active compound, resulting in the dissipation of ion gradients and the inhibition of respiration, the extent to which is species-specific. These effects initially do not halt the production of ATP. Understanding the mode of action of natural antimicrobials may facilitate their application as natural food preservatives, particularly for their potential use in preservation systems employing multiple hurdles.

    Olanexidine gluconate [1-(3,4-dichlorobenzyl)-5-octylbiguanide gluconate] (development code OPB-2045G) is a new monobiguanide compound with bactericidal activity. In this study, we assessed its spectrum of bactericidal activity and mechanism of action. The minimal bactericidal concentrations of the compound for 30-, 60-, and 180-s exposures were determined with the microdilution method using a neutralizer against 320 bacterial strains from culture collections and clinical isolates. Based on the results, the estimated bactericidal olanexidine concentrations with 180-s exposures were 869 μg/ml for Gram-positive cocci (155 strains), 109 μg/ml for Gram-positive bacilli (29 strains), and 434 μg/ml for Gram-negative bacteria (136 strains). Olanexidine was active against a wide range of bacteria, especially Gram-positive cocci, including methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci, and had a spectrum of bactericidal activity comparable to that of commercial antiseptics, such as chlorhexidine and povidone-iodine. In vitro experiments exploring its mechanism of action indicated that olanexidine (i) interacts with the bacterial surface molecules, such as lipopolysaccharide and lipoteichoic acid, (ii) disrupts the cell membranes of liposomes, which are artificial bacterial membrane models, (iii) enhances the membrane permeability of Escherichia coli, (iv) disrupts the membrane integrity of S. aureus, and (v) denatures proteins at relatively high concentrations (≥160 μg/ml). These results indicate that olanexidine probably binds to the cell membrane, disrupts membrane integrity, and its bacteriostatic and bactericidal effects are caused by irreversible leakage of intracellular components. At relatively high concentrations, olanexidine aggregates cells by denaturing proteins. This mechanism differs slightly from that of a similar biguanide compound, chlorhexidine. PMID:25987609

    Full Text Available Jinhua Li, Yuqin Qiao, Hongqin Zhu, Fanhao Meng, Xuanyong Liu State Key Laboratory of High Performance Ceramics and Superfine Microstructure, Shanghai Institute of Ceramics, Chinese Academy of Sciences, Shanghai, People’s Republic of China Abstract: Nanotopographical TiO2 films (including nanorod, nanotip, and nanowire topographies were successfully fabricated on the metallic Ti surface via hydrothermal treatment and then underwent Ag plasma immersion ion implantation to incorporate Ag with TiO2. The surface morphology, phase component, and chemical composition before and after Ag–PIII were characterized. In view of the potential clinical applications, both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus were used to estimate their antimicrobial effect. The nanostructured TiO2 films on a Ti surface exhibit a better bacteriostatic effect on both microbes compared to the pristine Ti. The nanotopographies of the TiO2 films affect the nucleation, growth, and distribution of Ag nanoparticles in the films during Ag–PIII process. The Ag nanoparticles are completely embedded into the nanorod film while partially exposed out of the nanotip and nanowire films, which account for the significant differences in the release behaviors of Ag ions in vitro. However, no significant difference exists in their antimicrobial activity against both microbes. The antimicrobial actions of the Ag@TiO2 system described here consist of two methods – the contact-killing action and the release-killing action. Nevertheless, based on the observed results, the contact-killing action should be regarded as the main method to destroy microbes for all the Ag plasma-modified TiO2 nanofilms. This study provides insight to optimize the surface design of Ti-based implants to acquire more effective antimicrobial surfaces to meet clinical applications.

  19. The effective action

    International Nuclear Information System (INIS)

    DeWitt, B.

    1987-01-01

    The concept of the effective action in quantum field theory was introduced into physics by Julian Schwinger in 1954. The effective action summarizes, in a single functional, all the quantum properties of the fields under consideration. The functional derivative of the effective action yields the effective field equations, which replace the classical field equations as descriptors of the dynamical behavior of quantized fields. Solutions of these equations are 'in-out' matrix elements of the field operators and, when substituted back into the effective action itself, yield logarithms of the corresponding 'in-out' amplitudes. The classical field equations are gauge covariant, a fact that derives from the gauge invariance of the classical action. One has learned how to construct effective actions that are similarly gauge invariant (in each order of perturbation theory) and that yield effective field equations having the covariance properties of their classical analogs. Despite this advance, problems remain, stemming from the fact that there is not one but an infinite number of gauge invariant effective actions, one for every background-covariant choice of supplementary conditions and ghost fields. Vilkovisky (1984) has argued persuasively that by requiring additionally that the effective action be invariant under local invertible changes in the choice of basic field variables, one can construct a natural unique gauge invariant effective action. This lecture will examine Vilkovisky's ideas. 3 refs

    The purpose of this study was to investigate the contribution of stereopsis to the processing of observed manipulative actions. To this end, we first combined the factors "stimulus type" (action, static control, and dynamic control), "stereopsis" (present, absent) and "viewpoint" (frontal, lateral) into a single design. Four sites in premotor, retro-insular (2) and parietal cortex operated specifically when actions were viewed stereoscopically and frontally. A second experiment clarified that the stereo-action-specific regions were driven by actions moving out of the frontoparallel plane, an effect amplified by frontal viewing in premotor cortex. Analysis of single voxels and their discriminatory power showed that the representation of action in the stereo-action-specific areas was more accurate when stereopsis was active. Further analyses showed that the 4 stereo-action-specific sites form a closed network converging onto the premotor node, which connects to parietal and occipitotemporal regions outside the network. Several of the specific sites are known to process vestibular signals, suggesting that the network combines observed actions in peripersonal space with gravitational signals. These findings have wider implications for the function of premotor cortex and the role of stereopsis in human behavior. © The Author 2016. Published by Oxford University Press.

    1975-01-01

    The purpose of the work described was to discover whether the antibiotics used in medicine can be sterilized by gamma rays; in this preliminary study, only the antimicrobic activity - the principal criterion for this type of medicament - was evaluated. Thirty-three products belonging to the various families of antibacterial and antifungic antibiotics were studied. The substances were irradiated in the dry state and in an aqueous solution, using a caesium-137 irradiator. The antibacterial and antifungic activity before and after irradiation was investigated by the method of diffusion in gelose. When irradiated in the dry state, 14 antibiotics preserve normal activity up to a dose of 10 Mrad; at doses between 5 and 10 Mrad, 15 other antibiotics are subject to a variable, but moderate, loss activity; and four register a slight loss of activity at a dose of 2.5 Mrad. In an aqueous solution all but two of the antibiotics suffer total loss of activity at a dose of 2.5 Mrad. As most commercial antibiotics are supplied in the dry state, gamma irradiation may be a useful sterilization process. However, preparations such as eye lotions, suspensions, ointments, etc. should be excepted

    Heat-inactivated normal human serum produces iron-reversible bacteriostasis of a number of microorganisms. This inhibitory effect was abolished by adsorption of serum with ultraviolet-killed cells of species that produce the siderophore enterochelin. Bacteriostasis also was alleviated by asorption of serum with 2,3-dihydroxy-N-benzoyl-L-serine, a degradation product of enterochelin, bound to the insoluble matrix AH-Sepharose 4B. Our results indicate that enterochelin-specific immunoglobulins exist in normal human serum. These immunoglobulins may act synergistically with transferrin to effect bacteriostasis of enterochelin-producing pathogens.

  5. Bacteriostatic effect of simvastatin on selected oral streptococci in vitro

    Full Text Available Context and Objective: Simvastatin is a widely used cholesterol-lowering drug, which has been found to have a number of pleiotropic effects. The aim of this study was to evaluate the antimicrobial effectiveness of simvastatin against selected oral streptococci as determined by the minimum inhibitory concentration (MIC. Methods: Streptococcus mutans, Streptococcus sanguis, Streptococcus anginosus, and Streptococcus salivarius were the test microorganisms. The serial dilution method was used to determine the MIC of simvastatin against these organisms. The MIC was defined as the lowest concentration of simvastatin that completely inhibited growth of the test organisms. Results: The data indicate that simvastatin inhibits the growth of the test organisms, with MIC's ranging from 7.8 to 15.6 μg/ml. Conclusions: Simvastatin has MIC's against the selected bacteria that compare favorably with reported values for topical agents such as essential oil, chlorhexidine gluconate, and triclosan. The levels of simvastatin required to inhibit bacterial growth of oral bacteria exceed the reported levels of the drug found in plasma or crevicular fluid of patients who are treated with this cholesterol-lowering drug. However, clinical studies are warranted to investigate the potential use of simvastatin as a novel antiplaque agent that could be used in local drug delivery to the oral cavity of those patients who are prescribed this cholesterol-lowering drug.

    Zinc is a known inhibitor of acid production by mutans streptococci. Our primary objective was to extend current knowledge of the physiologic bases for this inhibition and also for zinc inhibition of alkali production by Streptococcus rattus FA-1 and Streptococcus salivarius ATCC 13419. Zinc at concentrations as low as 0.01-0.1 mm not only inhibited acid production by cells of Streptococcus mutans GS-5 in suspensions or in biofilms but also sensitized glycolysis by intact cells to acidification. Zinc reversibly inhibited the F-ATPase of permeabilized cells of S. mutans with a 50% inhibitory concentration of about 1 mm for cells in suspensions. Zinc reversibly inhibited the phosphoenolpyruvate: sugar phosphotransferase system with 50% inhibition at about 0.3 mm ZnSO4, or about half that concentration when the zinc-citrate chelate was used. The reversibility of these inhibitory actions of zinc correlates with findings that it is mainly bacteriostatic rather than bactericidal. Zinc inhibited alkali production from arginine or urea and was a potent enzyme inhibitor for arginine deiminase of S. rattus FA-1 and for urease of S. salivarius. In addition, zinc citrate at high levels of 10-20 mm was weakly bactericidal.

    The national chair of Population Action International (formerly the Population Crisis Committee), Robin Chandler Duke, is a crusader for women's reproductive rights. She was in Bangladesh in 1971 during its civil war. Soldiers would rape young Muslim women, and their families would reject them when they became pregnant. The head of the exiled government agreed to let physicians from IPPF perform abortions on these women, which allowed families to take them back. Opposition to the abortions arose, however. This experience in Bangladesh sparked Ms. Duke's interest in population control. Her years as the wife of a US diplomat granted her access to powerful people worldwide. Her predecessor, retired US Army General Bill Draper, called Ms. Duke from his death bed in 1974 to ask her to be national chair of PAI. She served as a delegate in various international meetings, e.g., the 1980 UNESCO meetings in Belgrade. Spain and Luxembourg honored her for her work of campaigning for women's reproductive rights. She believes that rapid population growth is the most significant problem in the world today. It exacerbates poverty, environmental destruction, and political instability. She believes that universal availability of high quality, voluntary family planning services, including safe abortion, is needed to save humanity from the vicious cycle. Since family planning, sex education, and abortion are the most personal and sensitive parts of people's lives, Population Action frames family planning in the context of basic health care. AIDS complicates the issue, because contraception is no longer limited to birth control. Even though the organization realizes that sexual abstinence is the best way to avoid AIDS, it tries to educate female teenagers not to let boys coerce them to have sex. If they do, have sex Population Action advocates condom use. Ms. Duke cites the family planning successes of Indonesia, Zimbabwe, and Thailand.

  5. 'Action 2016': AREVA's strategic action plan

    On December 13, 2011, Luc Oursel, CEO, and Pierre Aubouin, Chief Financial Officer presented the group's strategic plan for the period 2012-2016. The plan has been drawn up collectively and is based on a thorough-going analysis and a realistic assessment of perspectives for all group activities and associated resources. Development of nuclear and renewable energies: the fundamentals are unchanged. In this context, the German decision remains an isolated case and the great majority of nuclear programs around the world have been confirmed. More conservative in its projections than the International Energy Agency, the group expects growth of 2.2% annually, reaching 583 GW of installed nuclear capacity by 2030, against 378 GW today. However, the Fukushima accident will lead to delays in launching new programs. 'Action 2016' plan aims to consolidate AREVA's leadership in nuclear energy and become a leading player in renewable energy. The group's strategic action plan 'Action 2016' is based on the following strategic choices: - commercial priority given to value creation, - selectivity in investments, - strengthening of the financial structure. These demand an improvement in the group's performance by 2015. This plan makes nuclear safety a strategic priority for the industrial and commercial performance of the group. This ambitious performance plan for the period 2012-2016 will give the group the wherewithal to withstand a temporary slowdown in the market resulting from the Fukushima accident and to deliver safe and sustainable growth of the business. The plan sets out the strategic direction for the group's employees for the years ahead: taking advantage of the expected growth in nuclear and renewable energies, targeted investment programs, and return to self-financing as of 2014

We prove that there is a natural action of a Renault-Deaconu groupoid on our fractafold bundle and that the resulting action groupoid is a Renault-Deaconu groupoid itself. We also show that when the bundle is locally compact the associated C^*-algebra is primitive and has a densely defined lower-semicontinuous trace.

Several operating curves developed by Monenco AGRA were described, among them the No Overtopping Curve (NOC), the Safe Filling Curve (SFC), the No Spill Curve (NSC) and the Guaranteed Fill Curve (GFC). The concept of an operational comfort zone was developed and defined. A flood action plan for all operating staff was created as a guide in case of a flooding incident. Staging of a flood action plan workshop was described. Dam break scenarios pertinent to the Bow River were developed for subsequent incorporation into a Flood Action Plan Manual. Evaluation of the technical presentations made during workshops were found them to have been effective in providing operating staff with a better understanding of the procedures that they would perform in an emergency. 8 figs

    This Mitigation Action Plan (MAP) focuses on mitigation commitments stated in the Supplemental Environmental Impact Statement (SEIS) and the Record of Decision (ROD) for the Naval Petroleum Reserve No. 1 (NPR-1). Specific commitments and mitigation implementation actions are listed in Appendix A-Mitigation Actions, and form the central focus of this MAP. They will be updated as needed to allow for organizational, regulatory, or policy changes. It is the intent of DOE to comply with all applicable federal, state, and local environmental, safety, and health laws and regulations. Eighty-six specific commitments were identified in the SEIS and associated ROD which pertain to continued operation of NPR-1 with petroleum production at the Maximum Efficient Rate (MER). The mitigation measures proposed are expected to reduce impacts as much as feasible, however, as experience is gained in actual implementation of these measures, some changes may be warranted.

    2005-09-01

    Full Text Available Affirmative action was launched by American presidents J.F. Kennedy and L.B. Johnson, yet by ironic historical accident it attained its greatest expansion and most radical form during R. Nixon’s conservative administration. Affirmative action was originally a government programme aimed at improving the social position of Afro-Americans, mostly in the sphere of employment and education, as a kind of compensation for racial discrimination, and also other forms of social injustice suffered by minority and underprivileged groups. Its goal was to increase the proportion of Afro-Americans, and later members of other minorities, as well as women, in higher education institutions and in various types of employment. It was supported by many social researchers and activists. Law courts, namely their verdicts and explanations in the case of precedents, had an especially important role in the debate on affirmative action. Political conservatives attacked various affirmative action programmes (especially preferential enrolment quotas for minority students, basing their criticism on the American constitutional principles on equal rights for every citizen. Market conservatives, furthermore, claimed that the government’s policy of racial preference brought into question the very basis of the capital system (competition and at the same time was not in the interest of the Afro-American working class. Namely, the social strata that profited most was the relatively affluent segment of the Afro-American community, which only increased economic and social differences within the latter. Recently the debate on affirmative action in the US has not been limited only to two opposing sides (liberals and conservatives. More and more scientists and other participants have recognised the negative aspects and also the failures of affirmative action, while at the same time refuting conservative opinions and goals.

    Three kinds of proper actions of increasing strength are defined. We prove that the three definitions specialize to the definitions by Bourbaki, by Palais and by Baum, Connes and Higson in their respective settings. The third of these, which thus turns out to be the strongest, originally only concerns actions of second countable locally compact groups on metrizable spaces. In this situation, it is shown to coincide with the other two definitions if the total space locally has the Lindelöf property and the orbit space is regular.

  8. Cognitive framing in action.

    2016-06-01

    Cognitive framing effects have been widely reported in higher-level decision-making and have been ascribed to rules of thumb for quick thinking. No such demonstrations have been reported for physical action, as far as we know, but they would be expected if cognition for physical action is fundamentally similar to cognition for higher-level decision-making. To test for such effects, we asked participants to reach for a horizontally-oriented pipe to move it from one height to another while turning the pipe 180° to bring one end (the "business end") to a target on the left or right. From a physical perspective, participants could have always rotated the pipe in the same angular direction no matter which end was the business end; a given participant could have always turned the pipe clockwise or counter-clockwise. Instead, our participants turned the business end counter-clockwise for left targets and clockwise for right targets. Thus, the way the identical physical task was framed altered the way it was performed. This finding is consistent with the hypothesis that cognition for physical action is fundamentally similar to cognition for higher-level decision-making. A tantalizing possibility is that higher-level decision heuristics have roots in the control of physical action, a hypothesis that accords with embodied views of cognition.

  6. Body posture modulates action perception.

    Science.gov (United States)

    Zimmermann, Marius; Toni, Ivan; de Lange, Floris P

    2013-04-03

    Recent studies have highlighted cognitive and neural similarities between planning and perceiving actions. Given that action planning involves a simulation of potential action plans that depends on the actor's body posture, we reasoned that perceiving actions may also be influenced by one's body posture. Here, we test whether and how this influence occurs by measuring behavioral and cerebral (fMRI) responses in human participants predicting goals of observed actions, while manipulating postural congruency between their own body posture and postures of the observed agents. Behaviorally, predicting action goals is facilitated when the body posture of the observer matches the posture achieved by the observed agent at the end of his action (action's goal posture). Cerebrally, this perceptual postural congruency effect modulates activity in a portion of the left intraparietal sulcus that has previously been shown to be involved in updating neural representations of one's own limb posture during action planning. This intraparietal area showed stronger responses when the goal posture of the observed action did not match the current body posture of the observer. These results add two novel elements to the notion that perceiving actions relies on the same predictive mechanism as planning actions. First, the predictions implemented by this mechanism are based on the current physical configuration of the body. Second, during both action planning and action observation, these predictions pertain to the goal state of the action.

    In recent years, focus has been on the utilisation of research-based knowledge and evidence in social work policy and practice in order to make it more effective. A part of this process has been the launch of knowledge portals to make use of knowledge from research. In this article, we investigate...... how knowledge portals about vulnerable children and youth present knowledge and evidence, and how they try to work as ?knowledge brokers? or intermediaries of evidence. We argue that knowledge portals are not merely channels for dissemination of knowledge. Knowledge portals could be considered as part...... of a greater process of bringing knowledge to action, encompassing the social and organisational contexts of research utilisation. The article concludes by stating that knowledge portals have the potential to be effective instruments in knowledge-to-action processes. The two main challenges, however...

  14. Hearing sounds, understanding actions: action representation in mirror neurons.

    Kohler, Evelyne; Keysers, Christian; Umiltà, M Alessandra; Fogassi, Leonardo; Gallese, Vittorio; Rizzolatti, Giacomo

    2002-08-02

    Many object-related actions can be recognized by their sound. We found neurons in monkey premotor cortex that discharge when the animal performs a specific action and when it hears the related sound. Most of the neurons also discharge when the monkey observes the same action. These audiovisual mirror neurons code actions independently of whether these actions are performed, heard, or seen. This discovery in the monkey homolog of Broca's area might shed light on the origin of language: audiovisual mirror neurons code abstract contents-the meaning of actions-and have the auditory access typical of human language to these contents.

    Baaquie, Belal E.; Du, Xin; Tanputraman, Winson

    2015-06-01

    A statistical generalization of microeconomics has been made in Baaquie (2013), where the market price of every traded commodity, at each instant of time, is considered to be an independent random variable. The dynamics of commodity market prices is modeled by an action functional-and the focus of this paper is to empirically determine the action functionals for different commodities. The correlation functions of the model are defined using a Feynman path integral. The model is calibrated using the unequal time correlation of the market commodity prices as well as their cubic and quartic moments using a perturbation expansion. The consistency of the perturbation expansion is verified by a numerical evaluation of the path integral. Nine commodities drawn from the energy, metal and grain sectors are studied and their market behavior is described by the model to an accuracy of over 90% using only six parameters. The paper empirically establishes the existence of the action functional for commodity prices that was postulated to exist in Baaquie (2013).

  16. Archetypes as action patterns.

    Science.gov (United States)

    Hogenson, George B

    2009-06-01

    The discovery of mirror neurons by researchers at the University of Parma promises to radically alter our understanding of fundamental cognitive and affective states. This paper explores the relationship of mirror neurons to Jung's theory of archetypes and proposes that archetypes may be viewed as elementary action patterns. The paper begins with a review of a proposed interpretation of the fainting spells of S. Freud in his relationship with Jung as an example of an action pattern that also defines an archetypal image. The challenge that mirror neurons present to traditional views in analytical psychology and psychoanalysis, however, is that they operate without recourse to a cognitive processing element. This is a position that is gaining increasing acceptance in other fields as well. The paper therefore reviews the most recent claims made by the Boston Process of Change Study Group as well as conclusions drawn from dynamic systems views of development and theoretical robotics to underline the conclusion that unconscious agency is not a requirement for coherent action. It concludes with the suggestion that this entire body of research may lead to the conclusion that the dynamic unconscious is an unnecessary hypothesis in psychoanalysis and analytical psychology.

    2018-05-01

    Full Text Available Context: This critical reflection is about the positive effects for educational and research settings of participation in a two-day programme entitled ‘Using participatory action research and appreciative inquiry to research healthcare practice’. Aims: To reflect on the journey of positive developments in research and education that started with participation in this programme. Using Caring Conversations (Dewar, 2011 as a reflective framework of questions, this article discusses the journey in order to encourage others to consider the approach of appreciative inquiry to bring to life the concept of co-creation in research and education. Conclusions and implications for practice: Participation in this programme has led to the implementation of a variety of actions in educational and research settings. Central to all these actions is an appreciative approach to co-creation as a counterpart to today’s prevailing problem-based viewpoint. A possible factor behind these developments was the power of vulnerability experienced during the programme, a shared process of transformational learning. Implications for practice: This critical reflection: Provides an invitation to shift from a problem-based focus to a positive revolution Provides an appreciative reflective story about the power of vulnerability as an inspiration for others to move out of their comfort zone and seek to discover their own exceptionality Supports a shift from a facilitator-led to a co-creation approach in doing research and teaching with older adults

  19. Finding minimal action sequences with a simple evaluation of actions

    Science.gov (United States)

    Shah, Ashvin; Gurney, Kevin N.

    2014-01-01

    Animals are able to discover the minimal number of actions that achieves an outcome (the minimal action sequence). In most accounts of this, actions are associated with a measure of behavior that is higher for actions that lead to the outcome with a shorter action sequence, and learning mechanisms find the actions associated with the highest measure. In this sense, previous accounts focus on more than the simple binary signal of “was the outcome achieved?”; they focus on “how well was the outcome achieved?” However, such mechanisms may not govern all types of behavioral development. In particular, in the process of action discovery (Redgrave and Gurney, 2006), actions are reinforced if they simply lead to a salient outcome because biological reinforcement signals occur too quickly to evaluate the consequences of an action beyond an indication of the outcome's occurrence. Thus, action discovery mechanisms focus on the simple evaluation of “was the outcome achieved?” and not “how well was the outcome achieved?” Notwithstanding this impoverishment of information, can the process of action discovery find the minimal action sequence? We address this question by implementing computational mechanisms, referred to in this paper as no-cost learning rules, in which each action that leads to the outcome is associated with the same measure of behavior. No-cost rules focus on “was the outcome achieved?” and are consistent with action discovery. No-cost rules discover the minimal action sequence in simulated tasks and execute it for a substantial amount of time. Extensive training, however, results in extraneous actions, suggesting that a separate process (which has been proposed in action discovery) must attenuate learning if no-cost rules participate in behavioral development. We describe how no-cost rules develop behavior, what happens when attenuation is disrupted, and relate the new mechanisms to wider computational and biological context. PMID:25506326

  3. Planning an action.

    Science.gov (United States)

    Gentilucci, M; Negrotti, A; Gangitano, M

    1997-06-01

    The motor control of a sequence of two motor acts forming an action was studied in the present experiment. The two analysed motor acts were reaching-grasping an object (first target) and placing it on a second target of the same shape and size (experiment 1). The aim was to determine whether extrinsic properties of the second target (i.e. target distance) could selectively influence the kinematics of reaching and grasping. Distance, position and size of both targets were randomly varied across the experimental session. The kinematics of the initial phase of the first motor act, that is, velocity of reaching and hand shaping of grasping, were influenced by distance of the second target. No kinematic difference was found between movements executed with and without visual control of both hand and targets. These results could be due to computation of the general program of an action that takes into account extrinsic properties of the final target. Conversely, they could depend on a visual interference effect produced by the near second target on the control of the first motor act. In order to dissociate the effects due to second target distance from those due to visual interference, two control experiments were carried out. In the first control experiment (experiment 2) subjects executed movements directed towards spatial locations at different distances from the first target, as in experiment 1. However, the near second target was not presented and subjects were required to place the object on an arbitrary near position. Distance of the second (either real or arbitrary) target affected the reaching component of the first motor act, as in experiment 1, but not the grasp component. In the second control experiment (experiment 3), the pure visual interference effect was tested. Subjects were required to reach and grasp the object and to lift it in either presence or absence of a second near stimulus. No effect on the initial phase of the first motor act was observed. The

    2011-11-17

    We present a computational approach to radical rhetoric that leverages the co-expression of rhetoric and action features in discourse to identify violent intent. The approach combines text mining and machine learning techniques with insights from Frame Analysis and theories that explain the emergence of violence in terms of moral disengagement, the violation of sacred values and social isolation in order to build computational models that identify messages from terrorist sources and estimate their proximity to an attack. We discuss a specific application of this approach to a body of documents from and about radical and terrorist groups in the Middle East and present the results achieved.

    A summary is presented of the low-level waste remedial action program at Los Alamos. The experimental design and progress is described for the experiments on second generation intrusion barriers, subsidence effects on SLB components, moisture cycling effects on chemical transport, and erosion control methodologies. The soil moisture data from the bio-intrusion and moisture cycling experiments both demonstrate the overwhelming importance of vegetation in minimizing infiltration of water through trench covers and backfill. Evaporation, as a water loss component in trench covers, is only effective in reducing soil moisture within 40 cm of the trench cover surface. Moisture infiltrating past the zone of evaporation in unvegetated or poorly vegetated trench covers is in storage and accumulates until drainage out of the soil profile occurs. Judicious selection of vegetation species for revegetating a low-level waste site may prevent infiltration of moisture into the trench and, when coupled with other design features (i.e. trench cover slope, tilling and seeding practice), may greatly reduce problems with erosion. Standard US Department of Agriculture erosion plots, when coupled with a state-of-the-art water balance and erosion model (CREAMS) promises to be highly useful in screening proposed remedial action cover designs for low-level waste sites. The erosion plot configuration allows for complete accounting of the water balance in a soil profile. This feature enables the user to optimize cover designs to minimize erosion and infiltration of water into the trench

  15. Sailing: Cognition, action, communication

    Directory of Open Access Journals (Sweden)

    Thora Tenbrink

    2017-12-01

    Full Text Available How do humans perceive and think about space, and how can this be represented adequately? For everyday activities such as locating objects or places, route planning, and the like, many insights have been gained over the past few decades, feeding into theories of spatial cognition and frameworks for spatial information science. In this paper, we explore sailing as a more specialized domain that has not yet been considered in this way, but has a lot to offer precisely because of its peculiarities. Sailing involves ways of thinking about space that are not normally required (or even acquired in everyday life. Movement in this domain is based on a combination of external forces and internal (human intentions that impose various kinds of directionality, affecting local action as well as global planning. Sailing terminology is spatial to a high extent, and involves a range of concepts that have received little attention in the spatial cognition community. We explore the area by focusing on the core features of cognition, action, and communication, and suggest a range of promising future areas of research in this domain as a showcase of the fascinating flexibility of human spatial cognition.

  16. Ontario's energy action plan

    International Nuclear Information System (INIS)

    2003-07-01

    In the fall of 2002, the government of Ontario announced an action plan designed to ensure stable electricity prices while additional electricity generating capacity is built. The action plan included a strategy for encouraging major private sector investments in wind, solar and other renewable energy sources. The strategies for new renewable energy projects include: property tax incentives, business income tax incentives, and sales tax rebates. Initiatives to increase supply include: Toronto's Portland 550 megawatt, natural gas-fired generating station, Niagara Falls' Beck Tunnel Project, and Windsor's 580 megawatt natural gas-fired generating station. The government is promoting energy conservation by reducing its electricity consumption by 10 per cent, and setting a target where 20 per cent of electricity consumed in the province must be from renewable energy sources. The use of interval meters by Ontario residents is being encouraged. A provincial sales tax rebate is being offered to customers buying select energy efficient appliances. In its commitment to environmental protection, the Ontario government is phasing out coal, offering rebates for solar energy systems, implementing measures to reduce acid rain, and investing $3.25 billion over ten years to renew and expand public transit. In Chatham, Ontario, a plant producing ethanol from corn was built, and others are planned for other parts of the province. Tax incentives are also offered for alternative fuel users. 1 ref., 1 tab

    2016-06-01

    We give a pedagogical introduction to the methodology of the Quench Action, which is an effective representation for the calculation of time-dependent expectation values of physical operators following a generic out-of-equilibrium state preparation protocol (for example a quantum quench). The representation, originally introduced in Caux and Essler (2013 Phys. Rev. Lett. 110 257203), is founded on a mixture of exact data for overlaps together with variational reasonings. It is argued to be quite generally valid and thermodynamically exact for arbitrary times after the quench (from short times all the way up to the steady state), and applicable to a wide class of physically relevant observables. Here, we introduce the method and its language, give an overview of some recent results, suggest a roadmap and offer some perspectives on possible future research directions.

    Significant increase in violent crimes in recent years forced Icelandic men to take action against violence. Television was seen as a major contributory factor in increasing violence. Surveys indicate that 10-15 years after television broadcasting commences in a particular society, the incidence of crime can be expected to double. While the majority of the individuals arrested for violent crimes are men, being male does not necessarily mean being violent. The Men's Committee of the Icelandic Equal Rights Council initiated a week-long information and education campaign under the theme "Men Against Violence". This campaign involved several events including an art exhibit, speeches on violence in families, treatment sought by those who are likely to resort to violence, booklet distribution among students in secondary schools, and a mass media campaign to raise public awareness on this pressing problem.

    Understanding the cellular response to ionizing radiation is not only necessary to meet the requirements of radioprotection, but also for medical application of radiation in cancer treatment. In terms of radiobiology, cancer therapy means the selective inactivation of malignant cells without affecting the normal healthy tissue. However, for several physical and biological reasons, this ideal situation is normally not attained. The elaboration of biophysical parameters that could be used to improve the selective sterilization of tumor cells has become one of the main activities of cellular radiobiology during the last two decades. Progress in this field has been facilitated by the development of tissue culture techniques allowing to grow and analyze cells in a synthetic nutrient medium. This chapter describes the physical and biological factors which determine cellular radiosensitivity and which are important to know for better understanding the cellular radiation action, in particular with reference to cancer treatment

While language structure analysis has led to the formulation of different grammatical formalisms and associated discriminative or generative computational models, the structure of action is still elusive and so are the related computational models. However, structuring action has important implications on action learning and generalization, in both human cognition research and computation. In this study, we present a biologically inspired generative grammar of action, which employs the structure-building operations and principles of Chomsky's Minimalist Programme as a reference model. In this grammar, action terminals combine hierarchically into temporal sequences of actions of increasing complexity; the actions are bound with the involved tools and affected objects and are governed by certain goals. We show, how the tool role and the affected-object role of an entity within an action drives the derivation of the action syntax in this grammar and controls recursion, merge and move, the latter being mechanisms that manifest themselves not only in human language, but in human action too.

  10. Viewpoint Manifolds for Action Recognition

    Full Text Available Abstract Action recognition from video is a problem that has many important applications to human motion analysis. In real-world settings, the viewpoint of the camera cannot always be fixed relative to the subject, so view-invariant action recognition methods are needed. Previous view-invariant methods use multiple cameras in both the training and testing phases of action recognition or require storing many examples of a single action from multiple viewpoints. In this paper, we present a framework for learning a compact representation of primitive actions (e.g., walk, punch, kick, sit that can be used for video obtained from a single camera for simultaneous action recognition and viewpoint estimation. Using our method, which models the low-dimensional structure of these actions relative to viewpoint, we show recognition rates on a publicly available dataset previously only achieved using multiple simultaneous views.

    and scale, the use of the object can provide a strong invariant for the detection of motion primitives. In this paper we propose an unsupervised learning approach for action primitives that makes use of the human movements as well as the object state changes. We group actions according to the changes......Action representation is a key issue in imitation learning for humanoids. With the recent finding of mirror neurons there has been a growing interest in expressing actions as a combination meaningful subparts called primitives. Primitives could be thought of as an alphabet for the human actions....... In this paper we observe that human actions and objects can be seen as being intertwined: we can interpret actions from the way the body parts are moving, but as well from how their effect on the involved object. While human movements can look vastly different even under minor changes in location, orientation...

  12. Everyday robotic action: Lessons from human action control

    2014-03-01

    Full Text Available Robots are increasingly capable of performing everyday human activities such as cooking, cleaning, and doing the laundry. This requires the real-time planning and execution of complex, temporally-extended sequential actions under high degrees of uncertainty, which provides many challenges to traditional approaches to robot action control. We argue that important lessons in this respect can be learned from research on human action control. We provide a brief overview of available psychological insights into this issue and focus on four principles that we think could be particularly beneficial for robot control: the integration of symbolic and subsymbolic planning of action sequences, the integration of feedforward and feedback control, the clustering of complex actions into subcomponents, and the contextualization of action-control structures through goal representations.

    Too often, credible scientific early warning information of increased disaster risk does not result in humanitarian action. With financial resources tilted heavily towards response after a disaster, disaster managers have limited incentive and ability to process complex scientific data, including uncertainties. These incentives are beginning to change, with the advent of several new forecast-based financing systems that provide funding based on a forecast of an extreme event. Given the changing landscape, here we demonstrate a method to select and use appropriate forecasts for specific humanitarian disaster prevention actions, even in a data-scarce location. This action-based forecasting methodology takes into account the parameters of each action, such as action lifetime, when verifying a forecast. Forecasts are linked with action based on an understanding of (1) the magnitude of previous flooding events and (2) the willingness to act "in vain" for specific actions. This is applied in the context of the Uganda Red Cross Society forecast-based financing pilot project, with forecasts from the Global Flood Awareness System (GloFAS). Using this method, we define the "danger level" of flooding, and we select the probabilistic forecast triggers that are appropriate for specific actions. Results from this methodology can be applied globally across hazards and fed into a financing system that ensures that automatic, pre-funded early action will be triggered by forecasts.

    A new coding system, 'Hazrad', for buildings and transportation containers for alerting emergency services personnel to the presence of radioactive materials has been developed in the United Kingdom. The hazards of materials in the buildings or transport container, together with the recommended emergency action, are represented by a number of codes which are marked on the building or container and interpreted from a chart carried as a pocket-size guide. Buildings would be marked with the familiar yellow 'radioactive' trefoil, the written information 'Radioactive materials' and a list of isotopes. Under this the 'Hazrad' code would be written - three symbols to denote the relative radioactive risk (low, medium or high), the biological risk (also low, medium or high) and the third showing the type of radiation emitted, alpha, beta or gamma. The response cards indicate appropriate measures to take, eg for a high biological risk, Bio3, the wearing of a gas-tight protection suit is advised. The code and its uses are explained. (U.K.)

    Synchronized movement is a ubiquitous feature of dance and music performance. Much research into the evolutionary origins of these cultural practices has focused on why humans perform rather than watch or listen to dance and music. In this study, we show that movement synchrony among a group of performers predicts the aesthetic appreciation of live dance performances. We developed a choreography that continuously manipulated group synchronization using a defined movement vocabulary based on arm swinging, walking and running. The choreography was performed live to four audiences, as we continuously tracked the performers' movements, and the spectators' affective responses. We computed dynamic synchrony among performers using cross recurrence analysis of data from wrist accelerometers, and implicit measures of arousal from spectators' heart rates. Additionally, a subset of spectators provided continuous ratings of enjoyment and perceived synchrony using tablet computers. Granger causality analyses demonstrate predictive relationships between synchrony, enjoyment ratings and spectator arousal, if audiences form a collectively consistent positive or negative aesthetic evaluation. Controlling for the influence of overall movement acceleration and visual change, we show that dance communicates group coordination via coupled movement dynamics among a group of performers. Our findings are in line with an evolutionary function of dance-and perhaps all performing arts-in transmitting social signals between groups of people. Human movement is the common denominator of dance, music and theatre. Acknowledging the time-sensitive and immediate nature of the performer-spectator relationship, our study makes a significant step towards an aesthetics of joint actions in the performing arts.

  19. Nonclassical Vitamin D Actions

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available It is becoming increasingly clear that vitamin D has a broad range of actions in the human body. Besides its well-known effects on calcium/phosphate homeostasis, vitamin D influences muscle function, cardiovascular homeostasis, nervous function, and the immune response. Vitamin D deficiency/insufficiency has been associated with muscle weakness and a high incidence of various chronic diseases such as cardiovascular disease, cancer, multiple sclerosis, and type 1 and 2 diabetes. Most importantly, low vitamin D status has been found to be an independent predictor of all-cause mortality. Several recent randomized controlled trials support the assumption that vitamin D can improve muscle strength, glucose homeostasis, and cardiovascular risk markers. In addition, vitamin D may reduce cancer incidence and elevated blood pressure. Since the prevalence of vitamin D deficiency/insufficiency is high throughout the world, there is a need to improve vitamin D status in the general adult population. However, the currently recommended daily vitamin D intake of 5–15 µg is too low to achieve an adequate vitamin D status in individuals with only modest skin synthesis. Thus, there is a need to recommend a vitamin D intake that is effective for achieving adequate circulating 25-hydroxyvitamin D concentrations (>75 nmol/L.

  20. Is credit for early action credible early action?

    International Nuclear Information System (INIS)

    Rolfe, C.; Michaelowa, A.; Dutschke, M.

    1999-12-01

    Credit for early action as a tool for greenhouse gas emissions reduction is compared with various market instruments as a means of narrowing the gap between projected emissions and those of the Kyoto Protocol. Market instruments work by creating a market price for emissions and use the market to encourage reductions at the lowest price, which is done by placing limits on greenhouse gas emissions and allowing the market to decide where reductions occur, or by imposing a carbon tax or emissions charge. While they can be applied within a sector, they are usually used to encourage reductions throughout the economy or across large sectors. Credit for early action also creates an incentive for emissions reductions throughout the economy or at least across many sectors. Credit for early action tools do not work by either imposing a carbon tax or emissions charge or placing limits on emissions, rather they promise that entities that take action against greenhouse gases prior to the imposition of a carbon tax or emissions limits will receive a credit against future taxes or limits. An overview is provided of the Kyoto Protocol and the rationale for taking early action, and a review is included of the theory and specific proposals for market instruments and credit for early action. A comparative analysis is provided of these approaches by examining their relative efficiency, environmental effectiveness, and impacts on the redistribution of wealth. Credit for early action is viewed as problematic on a number of counts and is seen as an interim strategy for imposition while political support for market instruments develop. The environmental effectiveness of credit for early action is very difficult to predict, and credit for early action programs do not yield the lowest cost emissions reductions. Credit for early action programs will not achieve compliance with the Kyoto Protocol at the lowest cost, and credits for early action will increase the compliance costs for those who

    We develop another method to get the Polyakov action that is: tile solution of tile conformal Ward identity on a Riemann surface Σ. We find that this action is the sum of two terms: the first one is expressed in terms of the projective connection and produces the diffeomorphism anomaly and tile second one is anomaly and contains the globally defined zero modes of the Ward identity. The explicit expression of this action is given on the complex plane. (author)

    The ability to infer deceptive intents from nonverbal behavior is critical for social interactions. By combining single-pulse and repetitive transcranial magnetic stimulation (TMS) in healthy humans, we provide both correlational and causative evidence that action simulation is actively involved in the ability to recognize deceptive body movements. We recorded motor-evoked potentials during a faked-action discrimination (FAD) task: participants watched videos of actors lifting a cube and judged whether the actors were trying to deceive them concerning the real weight of the cube. Seeing faked actions facilitated the observers' motor system more than truthful actions in a body-part-specific manner, suggesting that motor resonance was sensitive to deceptive movements. Furthermore, we found that TMS virtual lesion to the anterior node of the action observation network, namely the left inferior frontal cortex (IFC), reduced perceptual sensitivity in the FAD task. In contrast, no change in FAD task performance was found after virtual lesions to the left temporoparietal junction (control site). Moreover, virtual lesion to the IFC failed to affect performance in a difficulty-matched spatial-control task that did not require processing of spatiotemporal (acceleration) and configurational (limb displacement) features of seen actions, which are critical to detecting deceptive intent in the actions of others. These findings indicate that the human IFC is critical for recognizing deceptive body movements and suggest that FAD relies on the simulation of subtle changes in action kinematics within the motor system.

    Fantoni & Gerbino (2014) showed that subtle postural shifts associated with reaching can have a strong hedonic impact and affect how actors experience facial expressions of emotion. Using a novel Motor Action Mood Induction Procedure (MAMIP), they found consistent congruency effects in participants who performed a facial emotion identification task after a sequence of visually-guided reaches: a face perceived as neutral in a baseline condition appeared slightly happy after comfortable actions and slightly angry after uncomfortable actions. However, skeptics about the penetrability of perception (Zeimbekis & Raftopoulos, 2015) would consider such evidence insufficient to demonstrate that observer’s internal states induced by action comfort/discomfort affect perception in a top-down fashion. The action-modulated mood might have produced a back-end memory effect capable of affecting post-perceptual and decision processing, but not front-end perception. Here, we present evidence that performing a facial emotion detection (not identification) task after MAMIP exhibits systematic mood-congruent sensitivity changes, rather than response bias changes attributable to cognitive set shifts; i.e., we show that observer’s internal states induced by bodily action can modulate affective perception. The detection threshold for happiness was lower after fifty comfortable than uncomfortable reaches; while the detection threshold for anger was lower after fifty uncomfortable than comfortable reaches. Action valence induced an overall sensitivity improvement in detecting subtle variations of congruent facial expressions (happiness after positive comfortable actions, anger after negative uncomfortable actions), in the absence of significant response bias shifts. Notably, both comfortable and uncomfortable reaches impact sensitivity in an approximately symmetric way relative to a baseline inaction condition. All of these constitute compelling evidence of a genuine top-down effect on

    In a project funded by the Swedish Civil Contingencies Agency, the effort and work to reduce different kinds of accidents are being evaluated. The project wants to illuminate the links between actions and outcome, so we can learn from today's performance and in the future select more effective measures and overall deal with accidents more efficiently. The project ESS covers the field of frequent accidents such as sliding accidents at home, in house fires and less common accidents such as chemical and land fill accidents up to even more rare accidents such as natural accidents and hazards. In the ESS project SGI (Swedish geotechnical institute) will evaluate the work and effort concerning various natural hazards limited to landslides, erosion and flooding. The aim is to investigate how municipalities handle, especially prevention, of such natural disasters today. The project includes several aspects such as: • which are the driving forces for risk analysis in a municipality • do one use risk mapping (and what type) in municipal risk analysis • which aspects are most important when selecting preventive measures • in which way do one learn from past accidents • and from previous accidents elsewhere, by for example use existing databases • etc There are many aspects that play a role in a well-functioning safety promotion work. The overall goal is to examine present work and activities, highlight what is well functioning and identify weak points. The aim is to find out where more resources are needed and give suggestions for a more efficient security work. This includes identification of the most efficient "tools" in use or needed. Such tools can be education, directives, funding, more easily available maps and information regarding previous accidents and preventive measures etc. The project will result in recommendations for more effective ways to deal with landslides, erosion and flooding. Since different kinds of problems can occur depending on level of

For such, we will analyze the propositions of five thinkers who have work for the better understanding of this question. We will discuss the contributions of the Chicago School, especially psic-sociology, and Herbert Blumer symbolic interactionism; the classical Marxists approaches on collective actions; Claus Offe and the Marxist point of view on the new models of collective actions; Charles Tilly and his social-historic perspective analysis about social movements; and finally Mancur Olson and collective action from a rational perspective. What we intend is to present comparatively the theorical and practical similarities and exclusions of these contemporary authors who contribute with collective actions today.

    1996-03-01

    Full Text Available Action Research is one of the new generation of qualitative research methods in the social sciences which has special significance for nurses in South Africa. The collaborative, participative and reflective qualities of Action Research appeal to practitioners, and lend themselves to joint problem solving activities in local contexts. This paper sets out a rationale for Action Research, then describes its features, strengths, and limitations. Ways of overcoming the latter are suggested. The paper concludes that Action Research has potential application in the field of nursing, not only for the purposes of practical problem solving, but also for improving the personal and professional practice of nurses, and for emancipating nurses from their subordinate position in the hierarchy of health science.

    Full Text Available The typology of buyers and buying actions contracts are specific categories of consumer behaviour, determining group buyers and buying actions in classes, to fragment the markets. Market fragmentation through buyer typoligy and/or segmentation is presently characterized by a multitude of theoretical approaches and are especially generated by the common practice in the respective business. These two concepts are used for the same purpose, the essential difference being their starting point: the segmentation fragments the markets as a whole, while the typology of the buyer and of buying actions generate classifications starting from individual cases.

  3. The Neurobiology of Collective Action

    Directory of Open Access Journals (Sweden)

    Paul Joseph Zak

    2013-11-01

    Full Text Available This essay introduces a neurologically-informed mathematical model of collective action that reveals the role for empathy and distress in motivating costly helping behaviors. We report three direct tests of model with a key focus on the neuropeptide oxytocin as well as a variety of indirect tests. These studies, from our lab and other researchers, show support for the model. Our findings indicate that empathic concern, via the brain's release of oxytocin, is a trigger for collective action. We discuss the implications from this model for our understanding why human beings engage in costly collective action.

    2011-06-23

    Despite nearly two decades of research on mirror neurons, there is still much debate about what they do. The most enduring hypothesis is that they enable 'action understanding'. However, recent critical reviews have failed to find compelling evidence in favour of this view. Instead, these authors argue that mirror neurons are produced by associative learning and therefore that they cannot contribute to action understanding. The present opinion piece suggests that this argument is flawed. We argue that mirror neurons may both develop through associative learning and contribute to inferences about the actions of others.

    This study aimed to evaluate the potential for antimicrobial activity in vitro of extracts of bark and leaves of S. terebinthifolius treated with {sup 60}Co gamma radiation. 5,0 doses were used; 7.5 and 10 kGy, being held non-irradiated controls. To determine the antimicrobial activity was applied to the disc diffusion technique to evaluate the diameter of the inhibition zones against Gram-positive bacteria, gram-negative bacteria, alcohol-acid-resistant and yeast. Antimicrobial activity was considered significant for halos ≥ 15 mm. The results indicate an intensification of antimicrobial action of bark extracts, the 5.0 kGy, against S. aureus. Was held the micro dilution in broth to determine the minimum inhibitory concentration (MIC) and Minimum Bactericidal Concentration (MBC) of peels extracts, compared to eight clinical isolates of S. aureus. The MBC values showed that ionizing radiation did not produce the increased of anti bacteriostatic action of S. terebinthifolius, but the results indicated that S. terebinthifolius bark extracts can be used as an antimicrobial agent and ionizing radiation as an important alternative in this conservation feature.

  9. Biological Action Spectra (invited paper)

    International Nuclear Information System (INIS)

    Gruijl, F.R. de

    2000-01-01

    Ultraviolet (UV) radiation induces a wide variety of biological responses: ranging in humans from well-known short-term effects like sunburn to long-term effects like skin cancer. The wavelength dependencies ('action spectra') of the responses can differ significantly, depending on the UV-targeted molecules (their absorption spectra), their localisation (transmission to the target depth) and the photochemical reactions involved (e.g. quantum yields, competing reaction). An action spectrum (e.g. of sunburn) is usually determined in a wavelength by wavelength analysis of the response. This is not always possible (e.g. in case of skin cancer), and an action spectrum may then be extracted mathematically from differences in responses to broadband UV sources of various spectral compositions (yielding 'biological spectral weights'). However, relative spectral weights may shift with exposure levels and contributions from different wavelengths may not always add up. Under these circumstances conventional analyses will yield different action spectra for different experimental conditions. (author)

  10. Theory of direct interparticle action

    International Nuclear Information System (INIS)

    Vladimirov, Yu.S.; Turygin, A.Yu.

    1986-01-01

    Unusual point of view on the physical picture of the Universe and ratio between main physical categories is considered. Principal moments and theory peculiarities based on the conception of direct interparticle action are underlined. The direct interparticle action theory (DIAT) is considered from the position of choosing one or another axiomatics. At first the Fokker action principle is postulated there and then identical satisfiability of field equations is proved. All that relates to vacuum DIAT ignores and actions of matter formations are used as the basis. DIAT bears up against a global factor-account of absrbers of all surroundings (the Mach principle). The DIAT pretended to relativistic description of only additional concepts with the previously asigned space-time ratios. Concept for construction of the physical picture of the Universe, where classical space-time ratios being of secondary character, is suggested

    Instead of investigating the interference between two stationary, rectilinear wave functions in a trajectory representation by examining the two rectilinear wave functions individually, we examine a dichromatic wave function that is synthesized from the two interfering wave functions. The physics of interference is contained in the reduced action for the dichromatic wave function. As this reduced action is a generator of the motion for the dichromatic wave function, it determines the dichroma...

  2. Action representation: crosstalk between semantics and pragmatics.

    Science.gov (United States)

    Prinz, Wolfgang

    2014-03-01

    Marc Jeannerod pioneered a representational approach to movement and action. In his approach, motor representations provide both, declarative knowledge about action and procedural knowledge for action (action semantics and action pragmatics, respectively). Recent evidence from language comprehension and action simulation supports the claim that action pragmatics and action semantics draw on common representational resources, thus challenging the traditional divide between declarative and procedural action knowledge. To account for these observations, three kinds of theoretical frameworks are discussed: (i) semantics is grounded in pragmatics, (ii) pragmatics is anchored in semantics, and (iii) pragmatics is part and parcel of semantics. © 2013 Elsevier Ltd.

  3. RCRA corrective action determination of no further action

    International Nuclear Information System (INIS)

    1996-06-01

    On July 27, 1990, the U.S. Environmental Protection Agency (EPA) proposed a regulatory framework (55 FR 30798) for responding to releases of hazardous waste and hazardous constituents from solid waste management units (SWMUs) at facilities seeking permits or permitted under the Resource Conservation and Recovery Act (RCRA). The proposed rule, 'Corrective Action for Solid Waste Management Units at Hazardous Waste Facilities', would create a new Subpart S under the 40 CFR 264 regulations, and outlines requirements for conducting RCRA Facility Investigations, evaluating potential remedies, and selecting and implementing remedies (i.e., corrective measures) at RCRA facilities. EPA anticipates instances where releases or suspected releases of hazardous wastes or constituents from SWMUs identified in a RCRA Facility Assessment, and subsequently addressed as part of required RCRA Facility Investigations, will be found to be non-existent or non-threatening to human health or the environment. Such releases may require no further action. For such situations, EPA proposed a mechanism for making a determination that no further corrective action is needed. This mechanism is known as a Determination of No Further Action (DNFA) (55 FR 30875). This information Brief describes what a DNFA is and discusses the mechanism for making a DNFA. This is one of a series of Information Briefs on RCRA corrective action

  8. Action and reaction in the theories of direct interparticle action

    International Nuclear Information System (INIS)

    Narlikar, J.V.

    1975-01-01

    Newton's third law of motion is examined in the context of the theories of direct interpaticle action. In such theories, interactions between particles travel backward and forward in time at speeds not exceeding the speed of light. It is shown that while in the flat spacetime the equality of action and reaction can be clearly demonstrated, the situation is considerably more complicated in the curved spacetime. The phenomenon of gravitational scattering intervenes to destroy the equality of action and reaction. Nevertheless, when gravitation is taken into account, there is no violation of the conservation law of energy and momentum. These results are discussed in the framework of general relativity for the case of the electromagnetic interaction

    Bean, Rachel; Chung, Daniel J. H.; Geshnizjani, Ghazal

    2008-01-01

    If inflation is to be considered in an unbiased way, as possibly originating from one of a wide range of underlying theories, then observations need not be simply applied to reconstructing the inflaton potential V(φ) or a specific kinetic term, as in Dirac-Born-Infeld inflation, but rather to reconstruct the inflationary action in its entirety. We discuss the constraints that can be placed on a general single field action from measurements of the primordial scalar and tensor fluctuation power spectra and non-Gaussianities. The analytic form of the action that is consistent with data turns out to be surprisingly simple and easy to categorize. We also present the flow equation formalism for reconstructing a general inflationary Lagrangian L(X,φ), with X=(1/2)∂ μ φ∂ μ φ, in a general gauge, that reduces to canonical and DBI inflation in the specific gauge L X =c s -1 .

    2015-01-01

    This paper investigates how talk and practical action are coordinated during one type of activity involving professional communication: the service-assessment sequence in hair salons. During this activity, a practical inspection of the haircut must be coupled with sequentially produced verbal acts....... Our analysis of four examples reveals that there is no fixed relationship between the organization of talk and practical action. Instead, people manipulate this relationship on a moment-by-moment basis, often coordinating the two into a single, integral package, or relying on one stream of action...... to achieve progress in the other. These findings imply that some multimodal activities that are brought into alignment may have their own, separate and independent procedural logic and sequencing patterns and that these can be brought into play to create or deal with constraints in each other....

    1996-01-01

    A series of similar refueling floor events that occurred during the early 1990s prompted Susquehanna steam electric station (SSES) management to launch a broad-based review of how the Nuclear Department conducts business. This was accomplished through the formation of several improvement initiative teams. Clearly, one of the key areas that benefited from this management initiative was the corrective action program. The corrective action improvement team was charged with taking a comprehensive look at how the Nuclear Department identified and resolved problems. The 10-member team included management and bargaining unit personnel as well as an external management consultant. This paper provides a summary of this self-assessment initiative, including a discussion of the issues identified, opportunities for improvement, and subsequent completed or planned actions

    2007-01-01

    In this article, I argue that the representation of simple, bodily action has the function of endowing the narrative sequence with a visualizing power. It makes the narrated scenes or situations ready for visualization by the reader or listener. By virtue of this visualizing power or disposition...... an important visualizing function, these narrated actions have a communicative function and, as such, they can be said to belong to the domain of discourse-narratology. In the first part of the article, I argue that a certain type of plot-narratology, due to its retrospective epistemology and abstract...... definition of action, is unable to conceive of this visualizing function. In the second part, I argue that discourse-narratology fares no better since the visualizing function is independent of voice and focalization. In the final part, I sketch a possible account of the visualizing function of simple...

  14. Novel mechanisms for DHEA action.

    Prough, Russell A; Clark, Barbara J; Klinge, Carolyn M

    2016-04-01

    Dehydroepiandrosterone (3β-hydroxy-5-androsten-17-one, DHEA), secreted by the adrenal cortex, gastrointestinal tract, gonads, and brain, and its sulfated metabolite DHEA-S are the most abundant endogeneous circulating steroid hormones. DHEA actions are classically associated with age-related changes in cardiovascular tissues, female fertility, metabolism, and neuronal/CNS functions. Early work on DHEA action focused on the metabolism to more potent sex hormones, testosterone and estradiol, and the subsequent effect on the activation of the androgen and estrogen steroid receptors. However, it is now clear that DHEA and DHEA-S act directly as ligands for many hepatic nuclear receptors and G-protein-coupled receptors. In addition, it can function to mediate acute cell signaling pathways. This review summarizes the molecular mechanisms by which DHEA acts in cells and animal models with a focus on the 'novel' and physiological modes of DHEA action. © 2016 Society for Endocrinology.

    The study of group actions is more than a hundred years old but remains to this day a vibrant and widely studied topic in a variety of mathematic fields. A central development in the last fifty years is the phenomenon of rigidity, whereby one can classify actions of certain groups, such as lattices in semi-simple Lie groups. This provides a way to classify all possible symmetries of important spaces and all spaces admitting given symmetries. Paradigmatic results can be found in the seminal work of George Mostow, Gergory Margulis, and Robert J.

  16. Biological Action Spectra (invited paper)

    Energy Technology Data Exchange (ETDEWEB)

    Gruijl, F.R. de

    2000-07-01

    Ultraviolet (UV) radiation induces a wide variety of biological responses: ranging in humans from well-known short-term effects like sunburn to long-term effects like skin cancer. The wavelength dependencies ('action spectra') of the responses can differ significantly, depending on the UV-targeted molecules (their absorption spectra), their localisation (transmission to the target depth) and the photochemical reactions involved (e.g. quantum yields, competing reaction). An action spectrum (e.g. of sunburn) is usually determined in a wavelength by wavelength analysis of the response. This is not always possible (e.g. in case of skin cancer), and an action spectrum may then be extracted mathematically from differences in responses to broadband UV sources of various spectral compositions (yielding 'biological spectral weights'). However, relative spectral weights may shift with exposure levels and contributions from different wavelengths may not always add up. Under these circumstances conventional analyses will yield different action spectra for different experimental conditions. (author)

    ENGLISH ABSTRACT: In this paper the important .issues involved in successfully implementing corrective action systems in quality management are discussed. The work is based on experience in implementing and operating such a system in an automotive manufacturing enterprise in South Africa. The core of a corrective action system is good documentation, supported by a computerised information system. Secondly, a systematic problem solving methodology is essential to resolve the quality related problems identified by the system. In the following paragraphs the general corrective action process is discussed and the elements of a corrective action system are identified, followed by a more detailed discussion of each element. Finally specific results from the application are discussed.

  20. Nuclear emergencies and protective actions

    International Nuclear Information System (INIS)

    Sjoeblom, Klaus

    1995-01-01

    Although technical improvements have increased the safety of new and old nuclear power plants, many simultaneous component failures and/or human errors are improbable but possible. Both the plant (on-site) and the nearby area (off-site) have emergency plans. Rescue service authorities are responsible of the off-site. The main protective actions are sheltering, evacuation and iodine ingestion. The Loviisa off-site emergency plan assumes that a major part of this population takes care of their own protective actions; Rescue service authorities can then concentrate on the coordination activities and to those people who need help. To be able to carry out the protective actions timely and effectively the people should have information on radiation risk and emergency planning. In case of a potential accident the local population should follow the rescue service information and know how to shelter and how to evacuate themselves. Though there are many stockpiles of iodine pellets in the area the rescue service authorities recommend that each household should purchase iodine pellets for their own need. The utility and the rescue service authorities have distributed information brochures to all homes within 30 km from Loviisa NPP since 1990. This brochure gives information on radiation and protective actions in case of an accident. Because the brochures might not stay available and so also the local telephone book contains this information

  5. Action understanding as inverse planning.

    Baker, Chris L; Saxe, Rebecca; Tenenbaum, Joshua B

    2009-12-01

    Humans are adept at inferring the mental states underlying other agents' actions, such as goals, beliefs, desires, emotions and other thoughts. We propose a computational framework based on Bayesian inverse planning for modeling human action understanding. The framework represents an intuitive theory of intentional agents' behavior based on the principle of rationality: the expectation that agents will plan approximately rationally to achieve their goals, given their beliefs about the world. The mental states that caused an agent's behavior are inferred by inverting this model of rational planning using Bayesian inference, integrating the likelihood of the observed actions with the prior over mental states. This approach formalizes in precise probabilistic terms the essence of previous qualitative approaches to action understanding based on an "intentional stance" [Dennett, D. C. (1987). The intentional stance. Cambridge, MA: MIT Press] or a "teleological stance" [Gergely, G., Nádasdy, Z., Csibra, G., & Biró, S. (1995). Taking the intentional stance at 12 months of age. Cognition, 56, 165-193]. In three psychophysical experiments using animated stimuli of agents moving in simple mazes, we assess how well different inverse planning models based on different goal priors can predict human goal inferences. The results provide quantitative evidence for an approximately rational inference mechanism in human goal inference within our simplified stimulus paradigm, and for the flexible nature of goal representations that human observers can adopt. We discuss the implications of our experimental results for human action understanding in real-world contexts, and suggest how our framework might be extended to capture other kinds of mental state inferences, such as inferences about beliefs, or inferring whether an entity is an intentional agent.

  8. Action simulation: time course and representational mechanisms

    Science.gov (United States)

    Springer, Anne; Parkinson, Jim; Prinz, Wolfgang

    2013-01-01

    The notion of action simulation refers to the ability to re-enact foreign actions (i.e., actions observed in other individuals). Simulating others' actions implies a mirroring of their activities, based on one's own sensorimotor competencies. Here, we discuss theoretical and experimental approaches to action simulation and the study of its representational underpinnings. One focus of our discussion is on the timing of internal simulation and its relation to the timing of external action, and a paradigm that requires participants to predict the future course of actions that are temporarily occluded from view. We address transitions between perceptual mechanisms (referring to action representation before and after occlusion) and simulation mechanisms (referring to action representation during occlusion). Findings suggest that action simulation runs in real-time; acting on newly created action representations rather than relying on continuous visual extrapolations. A further focus of our discussion pertains to the functional characteristics of the mechanisms involved in predicting other people's actions. We propose that two processes are engaged, dynamic updating and static matching, which may draw on both semantic and motor information. In a concluding section, we discuss these findings in the context of broader theoretical issues related to action and event representation, arguing that a detailed functional analysis of action simulation in cognitive, neural, and computational terms may help to further advance our understanding of action cognition and motor control.

    Aimed to a deeper comprehension of a manifestly T-dual invariant formulation of string theory, in this paper a detailed comparison between the non-covariant action proposed by Tseytlin and the covariant one proposed by Hull is done. These are obtained by making both the string coordinates and their duals explicitly appear, on the same footing, in the world-sheet action, so “doubling” the string coordinates along the compact dimensions. After a discussion on the nature of the constraints in both the models and the relative quantization, it results that the string coordinates and their duals behave like “non-commuting” phase space coordinates but their expressions in terms of Fourier modes generate the oscillator algebra of the standard bosonic string. A proof of the equivalence of the two formulations is given. Furthermore, open-string solutions are also discussed

    1998-12-31

    In 1994--1996, within the framework of the US Country Studies Program, the Hungarian Country Study Team developed the national greenhouse gas emission inventory, and elaborated the mitigation options for the different sectors of the economy. In 1997, the development of a National Action Plan was begun as the continuation of this work. Results of the inventory study showed that greenhouse gas emissions decreased from the selected base level (i.e., from the yearly average emissions of 1985--1987) until 1994 by cca. 25%. However, this decrease was primarily caused by the deep economic recession. Therefore the policy makers have to face the problem of economic recovery without a relevant increase of greenhouse gas emissions in the near future. This is the main focus of the mitigation analysis and the National Action Plan.

    Kölle, Felix

    2016-01-01

    We experimentally investigate spillover effects of affirmative action policies in tournaments on subsequent team performance and the willingness to work in teams. In three different team environments, we find that such policies in form of gender quotas do not harm performance and cooperation within teams, and do not weaken people's willingness to work in teams. Our results, thus, provide further evidence that gender quotas can have the desired effect of promoting women without harming efficie...

  16. Knowledge in action in weaving

    Directory of Open Access Journals (Sweden)

    Viveka Berggren Torell

    2014-04-01

    Full Text Available The project “Design, craft and culture” had the purpose of co-production of knowledge between the University of Borås and the small-scale enterprise Vävkompaniet (The weaving company. The practitioners’ wanted to get insights into competences previously “hidden” in their knowledge in action; competences that could be the base for development of products and ways to reach customers. From academic point of view the main goal was to produce films aimed shedding light on knowledge in action. The result is four educational films aimed at students.This article is based on interpretations of films and interviews from places where the handweavers produce their products. A researcher and a weaving teacher studied their work, while the photographer filmed the artisans’ body movements. Questions and words, in a language which fits the events of the practice, can make practitioners sharpen their attention and direct it at critical points in the practice that they accomplish. By interviews done in a conversation-like way during observations, a space for such reflections was created. The weavers shared meanings on their position in the field of craft and detailed descriptions of crafting practices with the research team. Regarding the design process, because of their material rather than conceptual approach to craftwork, the weavers brought up the importance of sample weaving. While work with dressing the looms and weaving then continued many empirical examples of aspects of knowledge in action could be observed. The importance of routine, rhythm, bodily skills, senses, judgement and experience are brought up in the text.Key words: textile craft, weaving, tacit knowledge, knowledge in action, senses, visual ethnography

  18. Climate Action: Now or Never

    International Nuclear Information System (INIS)

    Auverlot, Dominique; Beeker, Etienne; Venturi, Richard

    2016-04-01

    The success of the Paris Agreement in rallying the world to take collective action against climate change and global warming has highlighted the stark challenge that lays ahead: Humankind must achieve a net zero carbon emissions target by the second half of this century. If the goal of keeping warming within 2 deg. C is to be met, all countries will have to reduce their greenhouse gas (GHG) emissions by about 30% more than the amount that was pledged in the run-up to the Paris conference in December 2015. This makes the action taken over the next decade absolutely critical in reaching this goal. The fact that affordable fossil fuels are likely to remain readily available is certain to complicate this collective effort even further. Together with the US and China, the European Union will have to go beyond its goal of reducing its emissions by 40% of its 1990 levels by 2030. This means it will have to both lower its consumption of fossil fuels - coal in particular - and create a credible carbon price signal for its economy by establishing a floor price in its Emissions Trading System (ETS) and possibly a European carbon tax. France, for its part, must concentrate on reducing emissions from transport, residential and commercial housing and agriculture as its emissions from electricity generation are already very low. Having brought down its emissions by close to 19% since 1990, France is clearly committed to taking climate action. The economic crisis notwithstanding, this reduction comes mostly from the manufacturing sector and energy production itself. However, if the country is to reach carbon neutrality by the second half of the 21. century without hampering its competitiveness, it will have to rethink the scope and rate of action to be taken.

  19. Riverland expedited response action proposal

    International Nuclear Information System (INIS)

    1993-04-01

    The US Environmental Protection Agency (EPA) and Washington Department of Ecology (Ecology) recommended that the US Department of Energy (DOE) prepare an expedited response action (ERA) for the Riverland Railroad Car Wash Pit and the 600 Area Army Munitions Burial Site. A non-time-critical ERA proposal includes preparation of an engineering evaluation/cost analysis (EE/CA) section. The EE/CA is a rapid, focused evaluation of available technologies using specific screening factors to assess feasibility, appropriateness, and cost. The ERA proposal will undergo reviews by Westinghouse Hanford Company (WHC), DOE, EPA, Ecology, and the public. Ecology and EPA will issue an Action Agreement Memorandum after resolution of all review comments. The, memorandum will authorize remediation activities. The ERA goal is to reduce the potential for any contaminant migration to the soil column, groundwater, and Columbia River. The ERA may be the final remediation of the 100-IU-1 Operable Unit. A No Action Record of Decision may be issued after cleanup completion

    Vesper, Cordula; Butterfill, Stephen; Knoblich, Günther

    2010-01-01

    What kinds of processes and representations make joint action possible? In this paper we suggest a minimal architecture for joint action that focuses on representations, action monitoring and action prediction processes, as well as ways of simplifying coordination. The architecture spells out...... minimal requirements for an individual agent to engage in a joint action. We discuss existing evidence in support of the architecture as well as open questions that remain to be empirically addressed. In addition, we suggest possible interfaces between the minimal architecture and other approaches...... to joint action. The minimal architecture has implications for theorizing about the emergence of joint action, for human-machine interaction, and for understanding how coordination can be facilitated by exploiting relations between multiple agents’ actions and between actions and the environment....

  3. Human action analysis with randomized trees

    CERN Document Server

    Yu, Gang; Liu, Zicheng

    2014-01-01

    This book will provide a comprehensive overview on human action analysis with randomized trees. It will cover both the supervised random trees and the unsupervised random trees. When there are sufficient amount of labeled data available, supervised random trees provides a fast method for space-time interest point matching. When labeled data is minimal as in the case of example-based action search, unsupervised random trees is used to leverage the unlabelled data. We describe how the randomized trees can be used for action classification, action detection, action search, and action prediction.

  4. Science education and everyday action

    Science.gov (United States)

    McCann, Wendy Renee Sherman

    2001-07-01

    This dissertation addresses three related tasks and issues in the larger field of science education. The first is to review of the several uses of "everydayness" at play in the science education literature, and in the education and social science literatures more generally. Four broad iterations of everydayness were found in science education, and these were traced and analyzed to develop their similarities, and contradictions. It was concluded that despite tendencies in science education research to suppose a fundamental demarcation either between professional science and everyday life, or between schools and everyday life, all social affairs, including professional science and activity in schools, are continuous with everyday life, and consist fundamentally in everyday, ordinary mundane actions which are ordered and organized by the participants to those social activities and occasions. The second task for this dissertation was to conduct a naturalistic, descriptive study of undergraduate-level physics laboratory activities from the analytic perspective of ethnomethodology. The study findings are presented as closely-detailed analysis of the students' methods of following their instructions and 'fitting' their observed results to a known scientific concept or principle during the enactment of their classroom laboratory activities. Based on the descriptions of students' practical work in following instructions and 'fitting'. The characterization of school science labs as an "experiment-demonstration hybrid" is developed. The third task of this dissertation was to synthesize the literature review and field study findings in order to clarify what science educators could productively mean by "everydayness", and to suggest what understandings of science education the study of everyday action recommends. It is argued that the significance of the 'experiment-demo hybrid' characterization must be seen in terms of an alternate program for science education research, which

  13. Congruent leadership: values in action.

    Science.gov (United States)

    Stanley, David

    2008-07-01

    To discuss the significance of an appropriate leadership theory in order to develop an understanding of clinical leadership. Leadership theories developed from management and related paradigms, particularly transformational leadership, may be ineffective in supporting nurses to gain insights into clinical leadership or to develop and implement clinical leadership skills. Instead, congruent leadership theory, based on a match between the clinical leaders' actions and their values and beliefs about care and nursing, may offer a more firm theoretical foundation on which clinical nurses can build an understanding of and capacity to implement clinical leadership or become clinical leaders. Evaluation The information used is drawn from the contemporary literature and a study conducted by the author. Leadership can be better understood when an appropriate theoretical foundation is employed. With regard to clinical leadership, congruent leadership is proposed as the most appropriate theory. It is important to recognize that leadership theories based on a management paradigm may not be appropriate for all clinical applications. Education should be aimed specifically at clinical leaders, recognizing that clinical leaders are followed not for their vision or creativity (even if they demonstrate these), but because they translate their values and beliefs about care into action.

  14. Lovelock action with nonsmooth boundaries

    Science.gov (United States)

    Cano, Pablo A.

    2018-05-01

    We examine the variational problem in Lovelock gravity when the boundary contains timelike and spacelike segments nonsmoothly glued. We show that two kinds of contributions have to be added to the action. The first one is associated with the presence of a boundary in every segment and it depends on intrinsic and extrinsic curvatures. We can think of this contribution as adding a total derivative to the usual surface term of Lovelock gravity. The second one appears in every joint between two segments and it involves the integral along the joint of the Jacobson-Myers entropy density weighted by the Lorentz boost parameter, which relates the orthonormal frames in each segment. We argue that this term can be straightforwardly extended to the case of joints involving null boundaries. As an application, we compute the contribution of these terms to the complexity of global anti-de Sitter space in Lovelock gravity by using the "complexity =action " proposal and we identify possible universal terms for arbitrary values of the Lovelock couplings. We find that they depend on the charge a* controlling the holographic entanglement entropy and on a new constant that we characterize.

    2014-10-01

    Tourette syndrome is a neuropsychiatric disorder characterized by tics. Tic generation is often linked to dysfunction of inhibitory brain networks. Some previous behavioral studies found deficiencies in inhibitory motor control in Tourette syndrome, but others suggested normal or even better-than-normal performance. Furthermore, neural correlates of action inhibition in these patients are poorly understood. We performed event-related functional magnetic resonance imaging during a stop-signal reaction-time task in 14 uncomplicated adult Tourette patients and 15 healthy controls. In patients, we correlated activations in stop-signal reaction-time task with their individual motor tic frequency. Task performance was similar in both groups. Activation of dorsal premotor cortex was stronger in the StopSuccess than in the Go condition in healthy controls. This pattern was reversed in Tourette patients. A significant positive correlation was present between motor tic frequency and activations in the supplementary motor area during StopSuccess versus Go in patients. Inhibitory brain networks differ between healthy controls and Tourette patients. In the latter the supplementary motor area is probably a key relay of inhibitory processes mediating both suppression of tics and inhibition of voluntary action. © 2014 International Parkinson and Movement Disorder Society.

  14. A Praxeological Approach to Intentional Action

    Directory of Open Access Journals (Sweden)

    Futerman Alan G.

    2017-10-01

    Full Text Available The concept of Intentional Action is at the core of Praxeology, as developed by the Austrian economist Ludwig von Mises. Under this unique approach, defined as the science of human action and designed to study the field of the social sciences, Mises create “action axiom”: the contention that every acting man more satisfactory state of affairs for a Austrian scholar is able to derive the fundament human action; such as value, scale of value, scarcity, abundance, profit, loss, uncertainty and causality, among others. This paper intends to present the praxeological perspective on intentional action and its epistemologic implications; it also attempts to answer objections to this thesis.

    1987-01-01

    The Reactor Emergency Action Level Monitor (REALM) Expert System is designed to provide assistance in the identification of a nuclear power plant emergency situation and the determination of its severity. REALM has been developed to operate in a real-time processing environment. REALM embodies a hybrid architecture utilizing both rule-based reasoning and object-oriented programming techniques borrowed from the Artificial Intelligence discipline of Computer Sciences. The rulebase consists of event-based rules and symptom-based rules. The symptom-based rules go beyond the current EAL structure to address the more problematic scenarios and entail a more symbolic representation of the plant information. The results to date have been encouraging that expert system technology can provide improved emergency decision-making capability in nuclear power plants

I argue that hoping serves as a meaning horizon, a gegenstand for adjusting to the ongoing challenges that living with illness impose on the families. Hoping is an imaginary backdrop, against which events and tasks, moods and impressions are experienced......Drawing on Vygotsky’s theory of imagination (Vygotsky 2004) I am proposing a phenomenology of hoping as fantasy in action. Based on analysis of 35 interviews with teenagers who are living in households with a somatically ill parent, I suggest that hoping plays a central role in the teenager...... and evaluated, and thus the fantasies involved in hoping becomes constitutive for experiencing. I apply Vygotsky’s experiential view of imaginary activities and explore the experiential status of the “imagined” and the relation between imagining and the real, through the empirical material on hope.

    The theory of dual radiation action (TDRA) was developed with the aim of applying microdosimetry to radiobiology. It therefore can deal only with the first phases in a long chain of events that results in patent effects. It is, however, clear that the initial spatial and temporal pattern of energy deposition has a profound influence on the ultimate outcome. As often happens, the early formulation of the theory contained a number of simplifying assumptions. Although most of these were explicitly stated when the first version of the TDRA was published experimental data obtained when the limitations are important were cited as contrary evidence causing considerable confusion. A more advanced version eliminated some of the restrictions but there remain others, one of which relates to certain aspects of saturation which are addressed here

    In social life actions are tightly linked with emotions. The integration of affective- and action-related information has to be considered as a fundamental component of appropriate social understanding. The present functional magnetic resonance imaging study aimed at investigating whether an emotion (Happiness, Anger or Neutral) dynamically expressed by an observed agent modulates brain activity underlying the perception of his grasping action. As control stimuli, participants observed the same agent either only expressing an emotion or only performing a grasping action. Our results showed that the observation of an action embedded in an emotional context (agent’s facial expression), compared with the observation of the same action embedded in a neutral context, elicits higher neural response at the level of motor frontal cortices, temporal and occipital cortices, bilaterally. Particularly, the dynamic facial expression of anger modulates the re-enactment of a motor representation of the observed action. This is supported by the evidence that observing actions embedded in the context of anger, but not happiness, compared with a neutral context, elicits stronger activity in the bilateral pre-central gyrus and inferior frontal gyrus, besides the pre-supplementary motor area, a region playing a central role in motor control. Angry faces not only seem to modulate the simulation of actions, but may also trigger motor reaction. These findings suggest that emotions exert a modulatory role on action observation in different cortical areas involved in action processing. PMID:23349792

  1. Efficient Temporal Action Localization in Videos

    State-of-the-art temporal action detectors inefficiently search the entire video for specific actions. Despite the encouraging progress these methods achieve, it is crucial to design automated approaches that only explore parts of the video which are the most relevant to the actions being searched. To address this need, we propose the new problem of action spotting in videos, which we define as finding a specific action in a video while observing a small portion of that video. Inspired by the observation that humans are extremely efficient and accurate in spotting and finding action instances in a video, we propose Action Search, a novel Recurrent Neural Network approach that mimics the way humans spot actions. Moreover, to address the absence of data recording the behavior of human annotators, we put forward the Human Searches dataset, which compiles the search sequences employed by human annotators spotting actions in the AVA and THUMOS14 datasets. We consider temporal action localization as an application of the action spotting problem. Experiments on the THUMOS14 dataset reveal that our model is not only able to explore the video efficiently (observing on average 17.3% of the video) but it also accurately finds human activities with 30.8% mAP (0.5 tIoU), outperforming state-of-the-art methods

    Objective: We investigated mothers' possession and display of action competence to counteract or prevent overweight and eventual obesity in their children. Action competence is defined as a personal resource where the most important aspect is the individual's wish to take action and to believe...... in its benefit. It unfolds within the room for action as experienced by the individual due to action obstacles and action potentials. Methods: In a case-control study, mothers of 111 overweight children (MOC) were compared with mothers of 149 nonoverweight children (MNC). They underwent a semistructured...... interview about action competence, lifestyle, and their 7- to 9-year-old children. Results: Compared to MNC, MOC considered it more important to change habits, both for themselves (p = 0.003) and their children (p

    Full Text Available In the present action learning implementation, twelve action learning sets were conducted over eight years. The action learning sets consisted of students involved in undergraduate engineering research thesis work. The concurrent study accompanying this initiative, investigated the influence of the action learning environment on student approaches to learning and any accompanying academic, learning and personal benefits realised. The influence of preferred learning styles on set function and student adoption of the action learning process were also examined. The action learning environment implemented had a measurable significant positive effect on student academic performance, their ability to cope with the stresses associated with conducting a research thesis, the depth of learning, the development of autonomous learners and student perception of the research thesis experience. The present study acts as an addendum to a smaller scale implementation of this action learning approach, applied to supervision of third and fourth year research projects and theses, published in 2010.

    Can playing action video games improve visuomotor control? If so, can these games be used in training people to perform daily visuomotor-control tasks, such as driving? We found that action gamers have better lane-keeping and visuomotor-control skills than do non-action gamers. We then trained non-action gamers with action or nonaction video games. After they played a driving or first-person-shooter video game for 5 or 10 hr, their visuomotor control improved significantly. In contrast, non-action gamers showed no such improvement after they played a nonaction video game. Our model-driven analysis revealed that although different action video games have different effects on the sensorimotor system underlying visuomotor control, action gaming in general improves the responsiveness of the sensorimotor system to input error signals. The findings support a causal link between action gaming (for as little as 5 hr) and enhancement in visuomotor control, and suggest that action video games can be beneficial training tools for driving. © The Author(s) 2016.

  8. Use of Action Research in Nursing Education

    Full Text Available Purpose. The purpose of this article is to describe action research in nursing education and to propose a definition of action research for providing guidelines for research proposals and criteria for assessing potential publications for nursing higher education. Methods. The first part of this project involved a search of the literature on action research in nursing higher education from 1994 to 2013. Searches were conducted in the CINAHL and MEDLINE databases. Applying the criteria identified, 80 publications were reviewed. The second part of the project involved a literature review of action research methodology from several disciplines to assist in assessing articles in this review. Results. This article summarizes the nursing higher education literature reviewed and provides processes and content related to four topic areas in nursing higher education. The descriptions assist researchers in learning more about the complexity of both the action research process and the varied outcomes. The literature review of action research in many disciplines along with the review of action research in higher education provided a framework for developing a nursing-education-centric definition of action research. Conclusions. Although guidelines for developing action research and criteria for publication are suggested, continued development of methods for synthesizing action research is recommended.

    The evaluation of the Research to Action project was conducted using an Outcome Mapping (OM) methodology (Earl et al. 2001) with a mixed-methods, repeat survey (before/after) study design. This design uses concurrent measurement of process and outcome indicators at baseline and follow-up. The RTA project proved effective at improving work environments and thereby promoting the retention and recruitment of nurses. Nurses involved in the RTA initiatives had a higher perception of leadership and support in their units, improved job satisfaction, increased empowerment and occupational commitment, and a greater intention to stay on the job.The pilot projects were most successful when there were clearly stated objectives, buy-in from nurses, support from the steering committee and management, and adequate communication among stakeholders. Committed coordination and leadership, both locally and nationally, were central to success.Considerable evidence has documented the challenges facing Canada's nursing human resources and their workplaces, such as high levels of turnover, excessive use of overtime and persistent shortages. There is a growing imperative to translate this research into action, and much of the available evidence presents viable policy alternatives for consideration. For example, a recent national synthesis report (Maddalena and Crupi 2008) recommended that, in consultation with stakeholders, processes should be put in place to share knowledge and best practices in nursing management, practice, staffing models and innovations in workplace health and well-being.Nurses across the country report a desire to be more involved in decisions affecting them and their patients (Wortsman and Janowitz 2006). A recent study on the shortage of registered nurses in Canada (Tomblin Murphy et al. 2009) highlighted the need for collaboration among governments, employers, unions and other stakeholders to improve working conditions for nurses.

    Research indicates that the public views zoos and aquariums as reliable and trusted sources for information on conservation (Ocean Project, 2009). The Aquarium of the Pacific is using NOAA's Science on a Sphere (SOS)° and linked flat screens to convey climate concepts to the public and serve as a model for how aquariums can promote climate literacy. The Ocean Science Center houses the SOS and is designed to immerse our visitors in an experience that extends from the sphere, to our live animals, and to our public programming. The first SOS exhibit, the sea level rise story, opened as the cornerstone of an aquarium-wide climate literacy strategy. Large panels next to the SOS prompts visitors to pledge actions to reduce their personal carbon footprint. The exhibit objectives were to provide a visual presentation that conveys a dramatic story about sea level rise, and to engage the audience in confronting the impact of sea level rise, and the local implications. The Aquarium utilized Yale's Six Americas survey instrument during summer 2010 to measure our audience interpretations of and responses to climate change. The survey showed that 78% of visitors categorized themselves as either alarmed or concerned about climate change, greater than the national average. Thus our climate literacy programs do not focus on convincing visitors of climate change and its causes, but on encouraging adaptive responses to varying scenarios. University of California, Berkeley, Lawrence Hall of Science Center for Research Evaluation and Assessment (REA) conducted a pre-opening evaluation of the exhibit's impact. The participants, 58% of whom were families with children, did not want to know more about climate change, but wanted tangible activities they could engage in to mitigate human induced effects, and more details about the impact of climate change on marine animals. REA stated that, "the sea level rise programs (both facilitated and non-facilitated) are well positioned to be

    Sensitivity to the regularities and structure contained within sequential, goal-directed actions is an important building block for generating expectations about the actions we observe. Until now, research on statistical learning for actions has solely focused on individual action sequences, but many actions in daily life involve multiple actors in various interaction contexts. The current study is the first to investigate the role of statistical learning in tracking regularities between actions performed by different actors, and whether the social context characterizing their interaction influences learning. That is, are observers more likely to track regularities across actors if they are perceived as acting jointly as opposed to in parallel? We tested adults and toddlers to explore whether social context guides statistical learning and-if so-whether it does so from early in development. In a between-subjects eye-tracking experiment, participants were primed with a social context cue between two actors who either shared a goal of playing together ('Joint' condition) or stated the intention to act alone ('Parallel' condition). In subsequent videos, the actors performed sequential actions in which, for certain action pairs, the first actor's action reliably predicted the second actor's action. We analyzed predictive eye movements to upcoming actions as a measure of learning, and found that both adults and toddlers learned the statistical regularities across actors when their actions caused an effect. Further, adults with high statistical learning performance were sensitive to social context: those who observed actors with a shared goal were more likely to correctly predict upcoming actions. In contrast, there was no effect of social context in the toddler group, regardless of learning performance. These findings shed light on how adults and toddlers perceive statistical regularities across actors depending on the nature of the observed social situation and the

    Project Rulison was a joint US Atomic Energy Commission (AEC) and Austral Oil Company (Austral) experiment, conducted under the AEC`s Plowshare Program, to evaluate the feasibility of using a nuclear device to stimulate natural gas production in low-permeability gas-producing geologic formations. The experiment was conducted on September 10, 1969, and consisted of detonating a 40-kiloton nuclear device at a depth of 2,568 m below ground surface (BGS). This Corrective Action Report describes the cleanup of petroleum hydrocarbon- and heavy-metal-contaminated sediments from an old drilling effluent pond and characterization of the mud pits used during drilling of the R-EX well at the Rulison Site. The Rulison Site is located approximately 65 kilometers (40 miles) northeast of Grand Junction, Colorado. The effluent pond was used for the storage of drilling mud during drilling of the emplacement hole for the 1969 gas stimulation test conducted by the AEC. This report also describes the activities performed to determine whether contamination is present in mud pits used during the drilling of well R-EX, the gas production well drilled at the site to evaluate the effectiveness of the detonation in stimulating gas production. The investigation activities described in this report were conducted during the autumn of 1995, concurrent with the cleanup of the drilling effluent pond.

    This paper reports several developments on the global efforts to combat abuse and violence against women and children. It is noted that in South Africa, Belem, Brazil, and Lesotho, protest actions were conducted against women and child abuse. Although the protests were made separately, the protests generally called for implementation of initiatives from the government to address the issue of child and women abuse. In the context of preventing abusive behaviors, a study by the University of Cape Town in South Africa on the appropriateness and feasibility of short-term community-based group therapy concluded that such an approach might be effective in treating delinquent behavior. In Indonesia, the Rifka Annisa Women's Crisis Centre is working to combat violence against women by providing services to victims; while in Israel, a media campaign is aiming to increase awareness and support for women's help centers. In addition, the government of Bangladesh has established a Cell Against Violence Against Women that provides legal counseling and assistance for civil and criminal cases related to violence against women. Furthermore, the WHO and the International Federation of Obstetricians and Gynecologists have collaborated to conduct a joint workshop to explore how violence against women can be eliminated.

    Full Text Available Choline is an essential nutrient for humans. It is a precursor of membrane phospholipids (e.g., phosphatidylcholine (PC, the neurotransmitter acetylcholine, and via betaine, the methyl group donor S-adenosylmethionine. High choline intake during gestation and early postnatal development in rat and mouse models improves cognitive function in adulthood, prevents age-related memory decline, and protects the brain from the neuropathological changes associated with Alzheimer’s disease (AD, and neurological damage associated with epilepsy, fetal alcohol syndrome, and inherited conditions such as Down and Rett syndromes. These effects of choline are correlated with modifications in histone and DNA methylation in brain, and with alterations in the expression of genes that encode proteins important for learning and memory processing, suggesting a possible epigenomic mechanism of action. Dietary choline intake in the adult may also influence cognitive function via an effect on PC containing eicosapentaenoic and docosahexaenoic acids; polyunsaturated species of PC whose levels are reduced in brains from AD patients, and is associated with higher memory performance, and resistance to cognitive decline.

    This solar action plan should be seen as a follow-up to the Danish Energy Agency's solar heating strategy from 2007, which showed great potential and opportunities for exploitation and use of solar heat in Denmark. In relation to the strategy from 2007, this action plan adjusted the distribution of solar heat from district heating plants and individual plants, but it is still the objective of this action plan to achieve the strategy's overall goal for 2030. With the implementation of the Action Plan in early 2012, it is estimated that in 2030 there will be about. 10 million m2 of solar collectors in operation, 8 million m2 for district heating and 2 million m2 for individual heating, equivalent to an installed capacity totaling 7 GW. The budget for actions in the Action Plan is about 80 million DKK annually over the next 5 years to initiate and ensure this development. (LN)

    2011-01-01

    According to a widely accepted constraint on the content of intentions, here called the exclusivity constraint, one cannot intend to perform another agent’s action, even if one might be able to intend that she performs it. For example, while one can intend that one’s guest leaves before midnight......, one cannot intend to perform her act of leaving. However, Deborah Tollefsen’s (2005) account of joint activity requires participants to have intentions-in-action (in John Searle’s (1983) sense) that violate this constraint. I argue that the exclusivity constraint should not be accepted...... as an unconditional constraint on the contents of intentions-in-action: one may intend to perform a basic action that belongs both to oneself and to another agent. Based on the phenomenology of tool use, I first argue that intentions-in-action of one’s basic actions may be technologically extended, meaning...

It represents the Laboratory`s framework for an affirmative approach to increasing the representation of people of color and women in segments of our work force where they have been underrepresented and taking action to increase the employment of persons with disabilities and special disabled and Vietnam era veterans. The AAP describes the hierarchy of responsibility for Laboratory affirmative action, the mechanisms that exist for full Laboratory participation in the AAP, the policies and procedures governing recruitment at all levels, the Laboratory`s plan for monitoring, reporting, and evaluating affirmative action progress, and a description of special affirmative action programs and plans the Laboratory has used and will use in its efforts to increase the representation and retention of groups historically underrepresented in our work force.

  4. SST: Single-Stream Temporal Action Proposals

    Our paper presents a new approach for temporal detection of human actions in long, untrimmed video sequences. We introduce Single-Stream Temporal Action Proposals (SST), a new effective and efficient deep architecture for the generation of temporal action proposals. Our network can run continuously in a single stream over very long input video sequences, without the need to divide input into short overlapping clips or temporal windows for batch processing. We demonstrate empirically that our model outperforms the state-of-the-art on the task of temporal action proposal generation, while achieving some of the fastest processing speeds in the literature. Finally, we demonstrate that using SST proposals in conjunction with existing action classifiers results in improved state-of-the-art temporal action detection performance.

    Full Text Available In a globalizing world, what role can social science research – particularly action research – play in order to address the risks of exclusion, poverty, social and physical insecurity and environmental deprivation? More specifically, how can this type of research be conducted in a participatory, responsible, transparent and scientific way? In other words: what about the ethics and standards in action research? This was the main focus of the World Congress on Action Research and Action Learning (August 2006 organized by the University of Groningen and the Higher Education Group of the Northern Netherlands. We begin by discussing the core characteristics of action research with reference to theory and practice. Reflection and action are key constituents of the process through the enactment of action research. The middle section draws upon the research findings presented at the congress and published in a book [B. Boog, J. Preece, M. Slagter and J. Zeelen (Eds. (2008 Towards Quality Improvement of Action Research. Developing Ethics and Standards, Rotterdam/Taipei: Sense Publishers]. Citing authors who contributed chapters to the book mentioned above, we analyze four important subthemes: ‘participation, power and rapport’; ‘quality of research and quality management’; ‘learning to solve your own problems in complex responsive social systems, and ‘heuristics (rules of thumb for action research practice’. Finally, we comment on possible quality improvements for action research. Our remarks relate to the problems of implementing the concept of participation, the ambition of action research to contribute to both knowledge production and social change and the need for systematic reconstruction (scientific validation of action research.

    Actions, which have effects in the external world, must be spatiotopically represented in the brain. The brain is capable of representing space in many different forms (e.g. retinotopic-, environment-, head- or shoulder-centred), but we maintain that actions are represented in action-centred space, meaning that, at the cellular level, the direction of movement is defined by the activity of cells. In reaching, for example, object location is defined as the direction and distance between the or...

  10. Corrective Action Decision Document for Corrective Action Unit 204: Storage Bunkers, Nevada Test Site, Nevada

    Boehlecke, Robert

    2004-01-01

    The six bunkers included in CAU 204 were primarily used to monitor atmospheric testing or store munitions. The 'Corrective Action Investigation Plan (CAIP) for Corrective Action Unit 204: Storage Bunkers, Nevada Test Site, Nevada' (NNSA/NV, 2002a) provides information relating to the history, planning, and scope of the investigation; therefore, it will not be repeated in this CADD. This CADD identifies potential corrective action alternatives and provides a rationale for the selection of a recommended corrective action alternative for each CAS within CAU 204. The evaluation of corrective action alternatives is based on process knowledge and the results of investigative activities conducted in accordance with the CAIP (NNSA/NV, 2002a) that was approved prior to the start of the Corrective Action Investigation (CAI). Record of Technical Change (ROTC) No. 1 to the CAIP (approval pending) documents changes to the preliminary action levels (PALs) agreed to by the Nevada Division of Environmental Protection (NDEP) and DOE, National Nuclear Security Administration Nevada Site Office (NNSA/NSO). This ROTC specifically discusses the radiological PALs and their application to the findings of the CAU 204 corrective action investigation. The scope of this CADD consists of the following: (1) Develop corrective action objectives; (2) Identify corrective action alternative screening criteria; (3) Develop corrective action alternatives; (4) Perform detailed and comparative evaluations of corrective action alternatives in relation to corrective action objectives and screening criteria; and (5) Recommend and justify a preferred corrective action alternative for each CAS within CAU 204

  11. Additive Routes to Action Learning: Layering Experience Shapes Engagement of the Action Observation Network.

    Science.gov (United States)

    Kirsch, Louise P; Cross, Emily S

    2015-12-01

    The way in which we perceive others in action is biased by one's prior experience with an observed action. For example, we can have auditory, visual, or motor experience with actions we observe others perform. How action experience via 1, 2, or all 3 of these modalities shapes action perception remains unclear. Here, we combine pre- and post-training functional magnetic resonance imaging measures with a dance training manipulation to address how building experience (from auditory to audiovisual to audiovisual plus motor) with a complex action shapes subsequent action perception. Results indicate that layering experience across these 3 modalities activates a number of sensorimotor cortical regions associated with the action observation network (AON) in such a way that the more modalities through which one experiences an action, the greater the response is within these AON regions during action perception. Moreover, a correlation between left premotor activity and participants' scores for reproducing an action suggests that the better an observer can perform an observed action, the stronger the neural response is. The findings suggest that the number of modalities through which an observer experiences an action impacts AON activity additively, and that premotor cortical activity might serve as an index of embodiment during action observation. © The Author 2015.

  1. Action principles for the Vlasov equation

    International Nuclear Information System (INIS)

    Ye, H.; Morrison, P.J.

    1992-01-01

    Five action principles for the Vlasov--Poisson and Vlasov--Maxwell equations, which differ by the variables incorporated to describe the distribution of particles in phase space, are presented. Three action principles previously known for the Vlasov--Maxwell equations are altered so as to produce the Vlasov--Poisson equation upon variation with respect to only the particle variables, and one action principle previously known for the Vlasov--Poisson equation is altered to produce the Vlasov--Maxwell equations upon variations with respect to particle and field variables independently. Also, a new action principle for both systems, which is called the leaf action, is presented. This new action has the desirable features of using only a single generating function as the dynamical variable for describing the particle distribution, and manifestly preserving invariants of the system known as Casimir invariants. The relationships between the various actions are described, and it is shown that the leaf action is a link between actions written in terms of Lagrangian and Eulerian variables

    Full Text Available Political actionism is the fenomen in social and art space, that appeared in middle of XX century as the practice of critic and protest with using different artistic methods and techniques. Political actionism as art and political tradition exist in postsoviet space, especially in Russia where actionism appeared in 1990 years and develops for actually days. In other countries this phenomenon not such systematic.  But analyze and compare actions in different countries appears the possibility to understand social and cultural context, their difference and similarity. Actionism is a reaction to external public, social and political situation, but its appearance more like the symptom of some problem than its critic or display – traditional approaches in art.  Appearance of actionism also connected with inability of manifestation of personal and civil liberty, that’s why in actions liberty affairs in such radical and hyperbolized forms. First volume of Russian political actionism began in 1990 years (Oleg Kulik, Alexander Brener, Anatoly Osmolovsky etc. and Second volume in 2010 (art-group Voina, Pussy Riot, Pyotr Pavlensky. This process not only a transformation of artistic and traditional space, but also modification of reaction on social and political situation. Actionism becomes a source of new type of knowledge, that give a possibility to see the habitual reality from another side and find in it new pointes and concepts. Political actionism contracting own interpretation of already well-established phenomenon. Usual concepts of liberty, authority, social control are deconstructed in actions. Those destructions of reality and cultural reorientation destroys traditional imposed patterns of interaction and social structure. But new views, that appeared in daily life from actions, often has mistaken interpretations. Exist a problem about identification of actions, its correct interpretations and understanding of its causes. In article was

  4. A neural network model of causative actions

    Directory of Open Access Journals (Sweden)

    Jeremy eLee-Hand

    2015-06-01

    Full Text Available A common idea in models of action representation is that actions are represented in terms of their perceptual effects (see e.g. Prinz, 1997; Hommel et al., 2001; Sahin et al., 2007; Umilta et al., 2008; Hommel et al., 2013. In this paper we extend existing models of effect-based action representations to account for a novel distinction. Some actions bring about effects that are independent events in their own right: for instance, if John 'smashes' a cup, he brings about the event of 'the cup smashing'. Other actions do not bring about such effects. For instance, if John 'grabs' a cup, this action does not cause the cup to 'do' anything: a grab action has well-defined perceptual effects, but these are not registered by the perceptual system that detects independent events involving external objects in the world. In our model, effect-based actions are implemented in several distinct neural circuits, which are organised into a hierarchy based on the complexity of their associated perceptual effects. The circuit at the top of this hierarchy is responsible for actions that bring about independently perceivable events. This circuit receives input from the perceptual module that recognises arbitrary events taking place in the world, and learns movements that reliably cause such events. We assess our model against existing experimental observations about effect-based motor representations, and make some novel experimental predictions. We also consider the possibility that the 'causative actions' circuit in our model can be identified with a motor pathway reported in other work, specialising in 'functional' actions on manipulable tools (Bub et al., 2008; Binkofski and Buxbaum, 2013.

  6. The time between intention and action affect the experience of action

    Directory of Open Access Journals (Sweden)

    Mikkel C. Vinding

    2015-06-01

    Full Text Available We present a study investigating how the delay between the intention to act and the following action, influenced the experience of action. In experiments investigating sense of agency and experience of action, the contrast is most often between voluntary and involuntary actions. It is rarely asked whether different types of intentions influence the experience of action differently. To investigate this we distinguished between proximal intentions (i.e. intentions for immediate actions and delayed intentions (i.e. intentions with a temporal delay between intention and action. The distinction was implemented in an intentional binding paradigm, by varying the delay between the time where participants formed the intention to act and the time at which they performed the action. The results showed that delayed intentions were followed by a stronger binding effect for the tone following the action compared to proximal intentions. The actions were reported to have occurred earlier for delayed intentions than for proximal intentions. This effect was independent of the binding effect usually found in intentional binding experiments. This suggests that two perceptual shifts occurred in the contrast between delayed intentions and proximal intentions: The first being the binding effect, the second a general shift in the perceived time of action. Neither the stronger binding effect for tone, nor the earlier reports of action, differed across delays for delayed intentions. The results imply that delayed intentions and proximal intentions have a different impact on the experience of action.

  15. Attention, biological motion, and action recognition.

    Science.gov (United States)

    Thompson, James; Parasuraman, Raja

    2012-01-02

    Interacting with others in the environment requires that we perceive and recognize their movements and actions. Neuroimaging and neuropsychological studies have indicated that a number of brain regions, particularly the superior temporal sulcus, are involved in a number of processes essential for action recognition, including the processing of biological motion and processing the intentions of actions. We review the behavioral and neuroimaging evidence suggesting that while some aspects of action recognition might be rapid and effective, they are not necessarily automatic. Attention is particularly important when visual information about actions is degraded or ambiguous, or if competing information is present. We present evidence indicating that neural responses associated with the processing of biological motion are strongly modulated by attention. In addition, behavioral and neuroimaging evidence shows that drawing inferences from the actions of others is attentionally demanding. The role of attention in action observation has implications for everyday social interactions and workplace applications that depend on observing, understanding and interpreting actions.

  17. Mechanisms underlying selecting objects for action

    Melanie eWulff

    2015-04-01

    Full Text Available We assessed the factors which affect the selection of objects for action, focusing on the role of action knowledge and its modulation by distracters. 14 neuropsychological patients and 10 healthy aged-matched controls selected pairs of objects commonly used together among distracters in two contexts: with real objects and with pictures of the same objects presented sequentially on a computer screen. Across both tasks, semantically related distracters led to slower responses and more errors than unrelated distracters and the object actively used for action was selected prior to the object that would be passively held during the action. We identified a sub-group of patients (N=6 whose accuracy was 2SD below the controls performances in the real object task. Interestingly, these impaired patients were more affected by the presence of unrelated distracters during both tasks than intact patients and healthy controls. Note the impaired had lesions to left parietal, right anterior temporal and bilateral pre-motor regions. We conclude that: (1 motor procedures guide object selection for action, (2 semantic knowledge affects action-based selection, (3 impaired action decision is associated with the inability to ignore distracting information and (4 lesions to either the dorsal or ventral visual stream can lead to deficits in making action decisions. Overall, the data indicate that impairments in everyday tasks can be evaluated using a simulated computer task. The implications for rehabilitation are discussed.

  1. Perception-Action in children with ASD

    Directory of Open Access Journals (Sweden)

    Claes eVon Hofsten

    2012-12-01

    Full Text Available How do disturbances to perception and action relate to the deficiencies expressed by children with autism? The ability to predict what is going to happen next is crucial for the construction of all actions and children develop these predictive abilities early in development. Children with autism, however, are deficient in the ability to foresee future events and to plan movements and movement sequences. They are also deficient in the understanding of other people’s actions. This includes communicative actions as they are ultimately based on movements. Today there are two promising neurobiological interpretation of ASD. First, there is strong evidence that the Mirror Neuron System (MNS is impaired. As stated by this hypothesis, action production and action understanding are intimately related. Both these functions rely on predictive models of the sensory consequences of actions and depend on connectivity between the parietal and pre-motor areas. Secondly, action prediction is accomplished through a system that includes a loop from the posterior parietal cortex through the cerebellum and back to the premotor and motor areas of the brain. Impairment of this loop is probably also part of the explanation of the prediction problems in children with ASD. Both the cortico-cerebellar loop and the MNS rely on distant neural connections. There are multiple evidence that such connections are weak in children with autism.

  6. Cyclone Simulation via Action Minimization

    Plotkin, D. A.; Weare, J.; Abbot, D. S.

    2016-12-01

    A postulated impact of climate change is an increase in intensity of tropical cyclones (TCs). This hypothesized effect results from the fact that TCs are powered subsaturated boundary layer air picking up water vapor from the surface ocean as it flows inwards towards the eye. This water vapor serves as the energy input for TCs, which can be idealized as heat engines. The inflowing air has a nearly identical temperature as the surface ocean; therefore, warming of the surface leads to a warmer atmospheric boundary layer. By the Clausius-Clapeyron relationship, warmer boundary layer air can hold more water vapor and thus results in more energetic storms. Changes in TC intensity are difficult to predict due to the presence of fine structures (e.g. convective structures and rainbands) with length scales of less than 1 km, while general circulation models (GCMs) generally have horizontal resolutions of tens of kilometers. The models are therefore unable to capture these features, which are critical to accurately simulating cyclone structure and intensity. Further, strong TCs are rare events, meaning that long multi-decadal simulations are necessary to generate meaningful statistics about intense TC activity. This adds to the computational expense, making it yet more difficult to generate accurate statistics about long-term changes in TC intensity due to global warming via direct simulation. We take an alternative approach, applying action minimization techniques developed in molecular dynamics to the WRF weather/climate model. We construct artificial model trajectories that lead from quiescent (TC-free) states to TC states, then minimize the deviation of these trajectories from true model dynamics. We can thus create Monte Carlo model ensembles that are biased towards cyclogenesis, which reduces computational expense by limiting time spent in non-TC states. This allows for: 1) selective interrogation of model states with TCs; 2) finding the likeliest paths for

    Action theory is the object of growing attention in a variety of scientific disciplines, and this is the first volume to offer a synthetic view of the range of approaches possible in the topic. The volume focuses on the nexus of formal action theory with a startlingly diverse set of subjects, which range from logic, linguistics, artificial intelligence, and automata theory to jurisprudence, deontology, and economics. It covers semantic, mathematical and logical aspects of action, showing how the problem of action breaks the boundaries of traditional branches of logic located in syntactics and semantics and now lies on lies on the borderline between logical pragmatics and praxeology.   The chapters here focus on specialized tasks in formal action theory, beginning with a thorough description and formalization of the language of action, and moving through material on the differing models of action theory to focus on probabilistic models, the relations of formal action theory to deontic logic, and its key appl...

  9. Recommended action levels for radon in dwellings

    1988-01-01

    The recommendation made by a group appointed by the Directorate of Public Health, arrives at the conclusion that radon in Norwegian dwellings implies a substantial health problem for the country. For this reason it is recommended that actions should be taken to reduce the radiation exposure from radon in Norway. Upper levels for such actions are set to 200 Bq/m 3 (radon in air of dwellings) for new contructions. For existing dwellings having concentrations of 200 - 800 Bq/m 3 , simple and unexpensive remedial actions to reduce levels are sufficient. When levels exceed 800 Bq/m 3 , more elaborate and costly actions are necessary. An evaluation of the extent of the radon problem in Norway is included, together with a survey of the cost and benefit involved in choosing various levels for remedial actions

    By integrating out the heavy fields in type II or heterotic string field theory one can construct the effective action for the light fields. This effective theory inherits all the algebraic structures of the parent theory and the effective action automatically satisfies the Batalin-Vilkovisky quantum master equation. This theory is manifestly ultraviolet finite, has only light fields as its explicit degrees of freedom, and the Feynman diagrams of this theory reproduce the exact scattering amplitudes of light states in string theory to any arbitrary order in perturbation theory. Furthermore in this theory the degrees of freedom of light fields above certain energy scale are also implicitly integrated out. This energy scale is determined by a particular parameter labelling a family of equivalent actions, and can be made arbitrarily low, leading to the interpretation of the effective action as the Wilsonian effective action.

    Maes, Pieter-Jan; Leman, Marc; Palmer, Caroline; Wanderley, Marcelo M

    2014-01-03

    The classical, disembodied approach to music cognition conceptualizes action and perception as separate, peripheral processes. In contrast, embodied accounts of music cognition emphasize the central role of the close coupling of action and perception. It is a commonly established fact that perception spurs action tendencies. We present a theoretical framework that captures the ways in which the human motor system and its actions can reciprocally influence the perception of music. The cornerstone of this framework is the common coding theory, postulating a representational overlap in the brain between the planning, the execution, and the perception of movement. The integration of action and perception in so-called internal models is explained as a result of associative learning processes. Characteristic of internal models is that they allow intended or perceived sensory states to be transferred into corresponding motor commands (inverse modeling), and vice versa, to predict the sensory outcomes of planned actions (forward modeling). Embodied accounts typically refer to inverse modeling to explain action effects on music perception (Leman, 2007). We extend this account by pinpointing forward modeling as an alternative mechanism by which action can modulate perception. We provide an extensive overview of recent empirical evidence in support of this idea. Additionally, we demonstrate that motor dysfunctions can cause perceptual disabilities, supporting the main idea of the paper that the human motor system plays a functional role in auditory perception. The finding that music perception is shaped by the human motor system and its actions suggests that the musical mind is highly embodied. However, we advocate for a more radical approach to embodied (music) cognition in the sense that it needs to be considered as a dynamical process, in which aspects of action, perception, introspection, and social interaction are of crucial importance.

  19. Efficient Interaction Recognition through Positive Action Representation

    Directory of Open Access Journals (Sweden)

    Tao Hu

    2013-01-01

    Full Text Available This paper proposes a novel approach to decompose two-person interaction into a Positive Action and a Negative Action for more efficient behavior recognition. A Positive Action plays the decisive role in a two-person exchange. Thus, interaction recognition can be simplified to Positive Action-based recognition, focusing on an action representation of just one person. Recently, a new depth sensor has become widely available, the Microsoft Kinect camera, which provides RGB-D data with 3D spatial information for quantitative analysis. However, there are few publicly accessible test datasets using this camera, to assess two-person interaction recognition approaches. Therefore, we created a new dataset with six types of complex human interactions (i.e., named K3HI, including kicking, pointing, punching, pushing, exchanging an object, and shaking hands. Three types of features were extracted for each Positive Action: joint, plane, and velocity features. We used continuous Hidden Markov Models (HMMs to evaluate the Positive Action-based interaction recognition method and the traditional two-person interaction recognition approach with our test dataset. Experimental results showed that the proposed recognition technique is more accurate than the traditional method, shortens the sample training time, and therefore achieves comprehensive superiority.

  20. Metaphysics of the principle of least action

    Terekhovich, Vladislav

    2018-05-01

    Despite the importance of the variational principles of physics, there have been relatively few attempts to consider them for a realistic framework. In addition to the old teleological question, this paper continues the recent discussion regarding the modal involvement of the principle of least action and its relations with the Humean view of the laws of nature. The reality of possible paths in the principle of least action is examined from the perspectives of the contemporary metaphysics of modality and Leibniz's concept of essences or possibles striving for existence. I elaborate a modal interpretation of the principle of least action that replaces a classical representation of a system's motion along a single history in the actual modality by simultaneous motions along an infinite set of all possible histories in the possible modality. This model is based on an intuition that deep ontological connections exist between the possible paths in the principle of least action and possible quantum histories in the Feynman path integral. I interpret the action as a physical measure of the essence of every possible history. Therefore only one actual history has the highest degree of the essence and minimal action. To address the issue of necessity, I assume that the principle of least action has a general physical necessity and lies between the laws of motion with a limited physical necessity and certain laws with a metaphysical necessity.

    Action potential is considered to be one of the primary responses of a plant to action of various environmental factors. Understanding plant action potential propagation mechanisms requires experimental investigation and simulation; however, a detailed mathematical model of plant electrical signal transmission is absent. Here, the mathematical model of action potential propagation in plants has been worked out. The model is a two-dimensional system of excitable cells; each of them is electrically coupled with four neighboring ones. Ion diffusion between excitable cell apoplast areas is also taken into account. The action potential generation in a single cell has been described on the basis of our previous model. The model simulates active and passive signal transmission well enough. It has been used to analyze theoretically the influence of cell to cell electrical conductivity and H(+)-ATPase activity on the signal transmission in plants. An increase in cell to cell electrical conductivity has been shown to stimulate an increase in the length constant, the action potential propagation velocity and the temperature threshold, while the membrane potential threshold being weakly changed. The growth of H(+)-ATPase activity has been found to induce the increase of temperature and membrane potential thresholds and the reduction of the length constant and the action potential propagation velocity.

  3. Brazilian union actions for workers' health protection

    Directory of Open Access Journals (Sweden)

    Rodolpho Repullo Junior

    Full Text Available CONTEXT: Many authors have emphasized the importance of worker strength through unionized organizations, in relation to the improvement of working procedures, and have reported on the decisiveness of labor movement actions in achieving modifications within the field of work and health. OBJECTIVE: To describe the ways in which Brazilian unions have tried to intervene in health-illness and work processes, identifying the existence of commonality in union actions in this field. TYPE OF STUDY: Qualitative study. SETTING: Postgraduate Program, Environmental Health Department, Faculdade de Saúde Pública, Universidade de São Paulo, São Paulo, Brazil. METHODS: Union health advisers and directors were interviewed. Documents relating to union action towards protecting workers' health were collected and analyzed. RESULTS: Unions articulate actions regarding workers' health of a technical and political nature that involve many aspects and high complexity. These have been divided into thematic categories for better analysis. DISCUSSION: Union actions regarding workers' health in Brazil are restricted to some unions, located mainly in the southern, southeastern and northeastern regions of the country. Nonetheless, the unions undertaking such actions represent many professions of great economic and political importance. CONCLUSIONS: The recent changes in health and safety at work regulations, recognition of professional diseases, creation of workers' health services and programs within the unified health system, and operational improvements in companies' specialized safety and occupational medicine services, all basically result from union action. There is commonality of union action in this field in its seeking of technical and political strengthening for all workers and their general and local representation. This has the objective of benefiting collective bargaining between employers and workers. Inter-institutional action on behalf of workers' rights

  10. Habits as action sequences: hierarchical action control and changes in outcome value.

    Science.gov (United States)

    Dezfouli, Amir; Lingawi, Nura W; Balleine, Bernard W

    2014-11-05

    Goal-directed action involves making high-level choices that are implemented using previously acquired action sequences to attain desired goals. Such a hierarchical schema is necessary for goal-directed actions to be scalable to real-life situations, but results in decision-making that is less flexible than when action sequences are unfolded and the decision-maker deliberates step-by-step over the outcome of each individual action. In particular, from this perspective, the offline revaluation of any outcomes that fall within action sequence boundaries will be invisible to the high-level planner resulting in decisions that are insensitive to such changes. Here, within the context of a two-stage decision-making task, we demonstrate that this property can explain the emergence of habits. Next, we show how this hierarchical account explains the insensitivity of over-trained actions to changes in outcome value. Finally, we provide new data that show that, under extended extinction conditions, habitual behaviour can revert to goal-directed control, presumably as a consequence of decomposing action sequences into single actions. This hierarchical view suggests that the development of action sequences and the insensitivity of actions to changes in outcome value are essentially two sides of the same coin, explaining why these two aspects of automatic behaviour involve a shared neural structure. © 2014 The Author(s) Published by the Royal Society.

    Social impairments in individuals with autism spectrum disorders (ASD) may be in part due to difficulty perceiving and recognizing the actions of others. Evidence from imitation studies, which involves both observation and execution of an action, suggests differences, in individuals with ASD, between the ability to imitate goal-directed actions involving objects (transitive actions) and the ability to imitate actions that do not involve objects (intransitive actions). In the present study, we examined whether there were differences in how ASD adolescents encoded transitive and intransitive actions compared to typically developing (TD) adolescents, by having participants view videos of a hand reaching across a screen toward an object or to where an object would be while functional magnetic resonance images were collected. Analyses focused on areas within the action observation network (AON), which is activated during the observation of actions performed by others. We hypothesized that the AON would differentiate transitive from intransitive actions only in the ASD group. However, results revealed that object presence modulated activity in the right inferior frontal gyrus and supramarginal gyrus of the TD group, a differentiation that was not seen in the ASD group. Furthermore, there were no significant group differences between the TD and ASD groups in any of the conditions. This suggests that there is not a global deficit of the AON in individuals with ASD while observing transitive and intransitive actions. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

    1986-01-01

    It is shown that Witten's (1986) open-bosonic-string field-theory action and a closed-string analog can be written as a purely cubic interaction term. The conventional form of the action arises by expansion around particular solutions of the classical equations of motion. The explicit background dependence of the conventional action via the Becchi-Rouet-Stora-Tyutin operator is eliminated in the cubic formulation. A closed-form expression is found for the full nonlinear gauge-transformation law.

    2010-02-01

    The paper aims at highlighting how our primary understanding of others' actions is rooted in the mirror mechanism. To this end, the anatomical architecture of the mirror neuron system for action will be outlined as well as its role in grasping goals and intentions in others' motor behaviour. One further step through the looking glass of social cognition will be referring to the ubiquitous emotional colouring of actions and considering its links with the motor domain. This will allow a clearer perspective on the mechanism underlying our abilities for emotional understanding and on cases in which these abilities are amiss, as in autistic spectrum disorders.

    The Safety-Related Operator Actions (SROA) Program was designed to provide information and data for use by NRC in assessing the performance of nuclear power plant (NPP) control room operators in responding to abnormal/emergency events. The primary effort involved collection and assessment of data from simulator training exercises and from historical records of abnormal/emergency events that have occurred in operating plants (field data). These data can be used to develop criteria for acceptability of the use of manual operator action for safety-related functions. Development of criteria for safety-related operator actions are considered

    2012-09-01

    Seymour B. Sarason's innovative ideas have influenced much of my work. These same ideas-in particular, his concepts of social settings, behavioral and programmatic regularities, and the universe of alternatives-also serve as the foundation for an action science of social settings. Questions regarding theory, measurement, intervention, and research design and data analysis are central to the development of this action science, and there have been recent innovations in each of these areas. However, future challenges remain for the field. We must continue to move forward to advance an action science of social settings and make a real difference in people's lives.

    2014-01-01

    Based on the connection between partial breaking of global supersymmetry, coset approach, which realized the given pattern of supersymmetry breaking, and the Nambu-Goto actions for the extended objects, we have constructed on-shell component action for N=1,D=5 supermembrane and its dual cousins. We demonstrate that the proper choice of the components and the use of the covariant (with respect to broken supersymmetry) derivatives drastically simplify the action: it can be represented as a sum of four terms each having an explicit geometric meaning

    2018-03-01

    We consider finitely generated free semigroup actions on a compact metric space and obtain quantitative information on Poincaré recurrence, average first return time and hitting frequency for the random orbits induced by the semigroup action. Besides, we relate the recurrence to balls with the rates of expansion of the semigroup generators and the topological entropy of the semigroup action. Finally, we establish a partial variational principle and prove an ergodic optimization for this kind of dynamical action.

    Subcommittee 6 of NPEC is responsible for the development of IEEE Standard 603. The adequacy of requirements concerning control and termination of protective actions was raised during the balloting of IEEE Standard 603-1980. In essence, the concern dealt with the requirement for deliberate operator action to return the system to normal. It was questioned if control actions such as automatic termination of system operation were allowed. Changes in the standard were made to clarify that there was a distinction between control (including termination) and return to normal and also state that automatic control may be required. Additionally, an action item was identified in the forward of IEEE Standard 603-1980 to determine if any additional changes were needed. The purpose of the paper is to present the results of this additional work

  12. Mechanism of action of sodium hypochlorite

    Directory of Open Access Journals (Sweden)

    Estrela Carlos

    2002-01-01

    Full Text Available The choice of an irrigating solution for use in infected root canals requires previous knowledge of the microorganisms responsible for the infectious process as well as the properties of different irrigating solutions. Complex internal anatomy, host defenses and microorganism virulence are important factors in the treatment of teeth with asymptomatic apical periodontitis. Irrigating solutions must have expressive antimicrobial action and tissue dissolution capacity. Sodium hypochlorite is the most used irrigating solution in endodontics, because its mechanism of action causes biosynthetic alterations in cellular metabolism and phospholipid destruction, formation of chloramines that interfere in cellular metabolism, oxidative action with irreversible enzymatic inactivation in bacteria, and lipid and fatty acid degradation. The aim of this work is to discuss the mechanism of action of sodium hypochlorite based on its antimicrobial and physico-chemical properties.

    Operative notes contain rich information about techniques, instruments, and materials used in procedures. To assist development of effective information extraction (IE) techniques for operative notes, we investigated the sublanguage used to describe actions within the operative report 'procedure description' section. Deep parsing results of 362,310 operative notes with an expanded Stanford parser using the SPECIALIST Lexicon resulted in 200 verbs (92% coverage) including 147 action verbs. Nominal action predicates for each action verb were gathered from WordNet, SPECIALIST Lexicon, New Oxford American Dictionary and Stedman's Medical Dictionary. Coverage gaps were seen in existing lexical, domain, and semantic resources (Unified Medical Language System (UMLS) Metathesaurus, SPECIALIST Lexicon, WordNet and FrameNet). Our findings demonstrate the need to construct surgical domain-specific semantic resources for IE from operative notes.
