2009-01-01

This paper presents the first comparative analysis of the relationship between natural gas storage utilization and price patterns at three major European trading points. Using two indirect tests developed by that are applied in other commodity markets, we impose the no arbitrage condition to model the efficiency of the natural gas market. The results reveal that while operators of European storage facilities realize seasonal arbitrage profits, substantial arbitrage potentials remain. We suggest that the indirect approach is well suited to provide market insights for periods with limited data. We find that overall market performance differs substantially from the competitive benchmark of the theory of storage. (author)

Perez, B.; Rojas, M.

1998-01-01

2990 sera samples from cattle were tested for antibodies to Brucella abortus using 8 serological tests for. The tests used were Rose Bengal (RBT), Buffer Plate Agglutination Test (BPAT), Complement Fixation (CFT), 2 Indirect and 2 Competitive Enzyme Linked Immunosorbent Assays (ELISA). Bacteriological evaluation from milk was done also. All tests were compared with respect to diagnostic specificity in vaccinated herds which were considered to be Brucella-free. The diagnostic specificity of the Indirect and Competitive ELISA was greater than 99,8%. Estimates of relative sensitivity were obtained from infected herds. The diagnostic sensitivity of the Indirect ELISA was greater than 95,8% and for the Competitive ELISA between 98,8 and 100 %, the last value refers to the Competitive ELISA Prototype II (SLPS antigen/M84 Mab), which was found highly suitable to differentiate vaccinated from brucella-infected cattle. The use of C-ELISA II for monitoring bovine populations under an eradication programme is recommended. (author)

Theoretical aspects of competitive advantage and competition

The concept of competitive advantage is well-known for many of us and a number of literary resources focused on entrepreneurship and functioning of economies deal with it, either directly or indirectly. The understanding of the term competitive advantage though sometimes varies. One can only perceive it when looking at it as a whole, a live organism that is constantly developing in a complex dynamic entrepreneurial environment, the individual parts of which do not function when separated from...

Changes in direct and indirect taxation in the process of the EU tax system reform

2015-01-01

Full Text Available Proceeding from the changes in direct and indirect taxation in the process of the EU tax system reform and the fact that new trends bring about vital social changes, the research in this area could add to the understanding of economic development of these countries. In the EU with its decentralized tax policy, changes in direct and indirect taxation are permanently implemented in the process of tax system reform. Harmonization of direct and indirect taxation in the EU is conducted by means of the adopted community law regulations. In the harmonization of direct taxation there is a tendency towards an increase of the level of fiscal coordination and elimination of barriers to the common market. Thus direct taxation reforms are limited to achieving higher level of coordination and preventing evasion and double taxation. The current policy is the result of the principle according to which fiscal competition has positive effects on reducing consumption and on the EU economic development. In the harmonization process the systems of indirect taxation are aligned particularly with excise duty and value added tax. Fiscal strategies in the reform process are mostly aimed at fiscal coordination, modernization, informative cooperation, evasion reduction and elimination of malpractices in fulfilling a VAT payment liability. Within the excise tax system minimal excise rates are determined and an environmentally-friendly policy is pursued. The main priorities of taxation changes within the harmonization process are in respect of evasion reduction and irrational fiscal competition on the EU market. A study of direct and indirect taxation changes in the process of the tax system reform is highly significant both from the aspect of efficient tax-system functioning, which results in achieving EU macroeconomic goals, and from the aspect of single states' interests in the process of transition and accession.

Competition rules and health care players: principles and consequences.

2012-01-01

Competition rules maximise consumer welfare by promoting efficient use of scarce resource and thus high output, low prices, high quality, varied services, innovation, production and distribution. European courts consider doctors and hospital staff as undertakings (any entity that performs economic activities), so that if they enter into agreements then they have to comply with competition rules. This paper's objective is to determine whether competition law, which applies to undertakings, can in fact be applied to different healthcare-sector players and whether specific rules are needed regarding competition between healthcare undertakings. Data were selected from relevant European and national case law, European institution legal documents (such as regulations, guidelines and communications) and healthcare competition law literature, and then examined. The paper finds that competition rules are applicable to healthcare players considering the consequences if competition rules are applied to the healthcare market. For market processes to result in the appropriate cost, quality and output, competition law must be proactive. In other words, quality must be fully factored into the competitive mix, allowing consumers to weigh healthcare price and non-price characteristics. Countries have different healthcare system and competition rules (although similar), competition rule impact is different for each country. Some healthcare systems are more regulated and there will be less opportunity for healthcare players to compete. Efficiently applying competition law to healthcare players means that several challenges need facing, such as healthcare quality complexity and court scepticism. This article points out the challenges when competition law is applied to the healthcare sector and how these challenges are faced in certain countries such as The Netherlands.

In natural communities, species are embedded in networks of direct and indirect interactions. Most studies on indirect interactions have focused on how they affect predator-prey or competitive relationships. However, it is equally likely that indirect interactions play an important structuring role in mutualistic relationships in a natural community.

1998-01-01

The different serologic techniques for bovine brucellosis diagnosis have different abilities to detect antibodies after vaccination with Brucella abortus strain 19. The humoral response in heifers vaccinated with Brucella abortus strain 19 was evaluated by using several serologic techniques. In the experimental field of INTA, Pilcaniyeu, Rio Negro province, sixteen 5 months old heifers were vaccinated subcutaneously with a standard dose (2ml, containing 20x10 9 to 10x10 9 living organisms) of Brucella abortus strain 19. Sera from all the heifers were obtained on 18 occasions (one 87 days before vaccination, one immediately before vaccination and on 16 occasions after vaccination, during 488 days) and analyzed by buffered plate antigen test, rose bengal test, standard tube agglutination test, 2-mercaptoetanol test, complement fixation test, indirect ELISA, and competitive ELISA. Prior vaccination, 100% of the heifers gave negative results in all the techniques used, while 100% of them gave positive reaction in the first sampling after vaccination to all the techniques, with the exception of standard tube agglutination test that showed agglutinating titters of 1/100 or higher (positive threshold) in only 71.4% of the heifers. The indirect ELISA technique showed a reducing percentage of positive animals up until 316 days after vaccination, after which positive results were obtained. The competitive ELISA gave positive results in a variable number of heifers up to 253 days after vaccination when 100% of the sera were negative to this technique. Buffered plate antigen test was the technique that gave positive results for a longest period, being 100% of the animals negative to this technique at 450 days after vaccination. The other serological techniques assayed gave positive results during variable periods of time, intermediate between standard tube agglutination test and buffered plate antigen test. Although the present results were obtained from a limited number of

The secreted aspartyl proteinases 2 (Sap2) of Candida albicans (C. albicans) is a potential marker of candididasis. It is a virulence factor associated with adherence and tissue invasion. In order to detect Sap2 in clinical sera, we developed an indirect competitive enzyme-linked immunosorbent assay (ELISA). Polyclonal antibodies were produced for Sap2 by injecting Sap2 into a New Zealand White inbred rabbit. They could be used at a dilution exceeding 1:1200 in an indirect ELISA, and detected Sap2 concentration up to 1 ng/mL. Of the 286 cancer serum samples tested, 16.8% were found as candidiasis. The test was simple and economical to perform and had a level of sensitivity for detection of low-titer positive sera; thus, it may be proven to be of value in epidemiological studies on candidiasis.

Indawan Syahri

2013-07-01

Full Text Available Abstract: Politeness principles are universally utilized by the speakers of any language when realizing various speech acts. However, the speakers of particular languages relatively apply politeness due to the cultural norms embedded. The present study attempts to delineate how the Indonesian learners of English (ILE apply the politeness principles in request realizations. Specifically it devotes to the types of politeness strategies applied and resemblance of the indirectness in politeness strategies in requesting acts. The FTAs and indirectness are the theoretical bases used to trace the typologies of both politeness and request strategies. The data werere collected by means of certain elicitation techniques, i.e. DCTs and Role-plays. The analyses werere done through three stages; determining request strategies, politeness strategies, and resemblance of indirectness in politeness. The results show that the indirectness generally is parallel to politeness. Besides, some pragmatic transfers are found in terms of applying native-culture norms in realizing target speech acts.

Environmental structure and competitive scoring advantages in team competitions

Science.gov (United States)

Merritt, Sears; Clauset, Aaron

2013-10-01

In most professional sports, playing field structure is kept neutral so that scoring imbalances may be attributed to differences in team skill. It thus remains unknown what impact environmental heterogeneities can have on scoring dynamics or competitive advantages. Applying a novel generative model of scoring dynamics to roughly 10 million team competitions drawn from an online game, we quantify the relationship between the structure within a competition and its scoring dynamics, while controlling the impact of chance. Despite wide structural variations, we observe a common three-phase pattern in the tempo of events. Tempo and balance are highly predictable from a competition's structural features alone and teams exploit environmental heterogeneities for sustained competitive advantage. Surprisingly, the most balanced competitions are associated with specific environmental heterogeneities, not from equally skilled teams. These results shed new light on the design principles of balanced competition, and illustrate the potential of online game data for investigating social dynamics and competition.

This research analyzes the direct and indirect relationships among self-motivation, perceived competition and psychological well-being and ill-being. Data from 491 Spanish college students (299 men and 192 women) who practice sports were collected using a cross-sectional design. Statistical analyses were carried out using structural equation modeling. Psychological well-being was directly fostered by perceived competition and indirectly by self- motivation. Furthermore, perceived competition was negatively associated with psychological ill-being. Perceived competition and self-motivation are important to the psychological well-being of college students and to avoiding ill-being.

Retail competition

International Nuclear Information System (INIS)

1998-01-01

Retail competition as the cornerstone of a competitive electricity marketplace was the subject of the seventh in the series of policy discussion papers developed at the Market Design Conference. Concern was expressed that because of the complexities involved in market design and technical implementation, the retail competition may lag behind other elements of the implementation of the new market design. A variety of key issues were debated, including the role of physical versus financial contracts, the form of retail competition and financial settlement systems in the short term, the requirement to separate 'competitive' (metering, billing, maintenance, consumer education) from non-competitive' (the transmission wires) services and the role of municipal electric utilities. It was agreed that the IMO should play an important role in defining and enforcing the separation of services, and that as a general rule, the development of policy in this area should be guided by the principle of maximizing the potential for competition

Energy Tax and Competition in Energy Efficiency. The Case of Consumer Durables

International Nuclear Information System (INIS)

Conrad, K.

2000-01-01

The purpose of this paper is to analyze the role of an energy tax on technical improvements and on prices of consumer durables induced by strategic competition in energy efficiency. If the gasoline tax is raised this does in principle not affect the producers of cars because the motorist pays for it in terms of a higher cost of using the car. This, however, affects the unit sales of car producers because of substitution towards other modes of transportation. A second element of reaction to energy price variation is an indirect one and relates to the effect of energy prices on technology. Competition forces car producers to develop more energy efficient cars in order to reduce the cost of using a car. This indirect effect can partly offset the direct effect of higher energy prices on demand if it is profitable for the automobile industry to engineer more energy efficient equipment. We will analyze the impact of an energy tax on energy efficiency and on the price of a durable good. This will be done within the framework of a duopoly competing in prices and in the energy efficiency of its products. The government chooses a welfare maximizing energy tax as an incentive to innovate. Then we will analyze a strategic two-stage decision process in which the duopolists first decide about energy efficiency and then compete in prices. 18 refs

Has renewable energy induced competitive behavior in the Spanish electricity market?

International Nuclear Information System (INIS)

Ciarreta, Aitor; Espinosa, Maria Paz; Pizarro-Irizar, Cristina

2017-01-01

Recent energy policy has favored a massive introduction of Renewable Energy Sources on electricity markets, which has greatly impacted their performance. First, the electricity price has decreased as a consequence of the so-called merit-order effect. Another relevant effect is associated to the intermittent nature of Renewable Energy, which has increased the cost of ancillary services. A third and important aspect, less addressed in the literature, is the induced change in the strategic behavior of the conventional electricity producers. In principle, the entry of new generators in a concentrated market would make it more competitive and change the strategic behavior of the incumbents. We test this hypothesis for the Spanish wholesale market. While we find no significant change in behavior for Nuclear, Hydropower and Coal, a change is observed in Combined Cycle bidding strategies after the entry of renewable generators. Our analysis shows that the massive entry of Renewable Energy Sources made other generators' behavior more competitive in the short run, but the effect was not persistent. - Highlights: • The indirect effects of RES affect prices in electricity markets. • RES induced little change in Nuclear, Coal and Hydropower generation. • Combined Cycle bidding strategies have evolved to adapt to the introduction of RES. • RES made Combined Cycle's behavior more competitive in the short run. • The competitive effect induced by RES is not persistent in the long run.

A highly sensitive and specific SPR-based competitive immunoassay for the detection of Thiabendazole (TBZ) has been developed. An indirect format where a TBZ-protein conjugate is immobilized onto gold surfaces has been selected. Under the optimal conditions, a LOD of 0.67 nM (0.13 μg L(-1)) and an IC(50) of 3.2 nM (0.64 μg L(-1)) have been achieved which are comparable to the values obtained by conventional ELISA. Analysis of real samples has been attempted by first evaluating the influence of complex matrix samples coming from whole oranges and secondly measuring samples containing TBZ previously evaluated by chromatographic methods. A methanolic extraction procedure followed by a simple dilution in assay buffer has proven to be sufficient to measure orange samples using the developed immunoassay with an excellent recovery percentage. The sensitivity and the feasibility of measuring whole orange samples demonstrate the effectiveness and robustness of the SPR biosensor, which can be useful for the determination of TBZ in food at concentrations below the Maximum Residue Levels (MRLs) established by the European legislation.

Apparent competition and native consumers exacerbate the strong competitive effect of an exotic plant species.

Direct and indirect effects can play a key role in invasions, but experiments evaluating both are rare. We examined the roles of direct competition and apparent competition by exotic Amur honeysuckle (Lonicera maackii) by manipulating (1) L. maackii vegetation, (2) presence of L. maackii fruits, and (3) access to plants by small mammals and deer. Direct competition with L. maackii reduced the abundance and richness of native and exotic species, and native consumers significantly reduced the abundance and richness of native species. Although effects of direct competition and consumption were more pervasive, richness of native plants was also reduced through apparent competition, as small-mammal consumers reduced richness only when L. maackii fruits were present. Our experiment reveals the multiple, interactive pathways that affect the success and impact of an invasive exotic plant: exotic plants may directly benefit from reduced attack by native consumers, may directly exert strong competitive effects on native plants, and may also benefit from apparent competition.

The aim of the present questionnaire study was to separate the effects of motivation- and competition-related variables on academic cheating by Hungarian high school students (N = 620, M = 264, F = 356. Structural equation modeling showed that intrinsic motivation has a negative effect, and amotivation has a positive indirect effect on self-reported academic cheating. In contrast, extrinsic motivation had no significant effect. Indirect positive influence on cheating, based on some characteristics of hypercompetition, was also found, whereas attitudes towards self-developmental competition had a mediated negative influence. Neither constructive nor destructive competitive classroom climate had a significant impact on academic dishonesty. Acceptance of cheating and guilt has significant and direct effect on self-reported cheating. In comparison with them, the effects of motivational and competition-related variables are relatively small, even negligible. These results suggest that extrinsic motivation and competition are not amongst the most reliable predictors of academic cheating behavior.

Direct and indirect effects of climate change on a prairie plant community.

Directory of Open Access Journals (Sweden)

Peter B Adler

2009-09-01

Full Text Available Climate change directly affects species by altering their physical environment and indirectly affects species by altering interspecific interactions such as predation and competition. Recent studies have shown that the indirect effects of climate change may amplify or counteract the direct effects. However, little is known about the the relative strength of direct and indirect effects or their potential to impact population persistence.We studied the effects of altered precipitation and interspecific interactions on the low-density tiller growth rates and biomass production of three perennial grass species in a Kansas, USA mixed prairie. We transplanted plugs of each species into local neighborhoods of heterospecific competitors and then exposed the plugs to a factorial manipulation of growing season precipitation and neighbor removal. Precipitation treatments had significant direct effects on two of the three species. Interspecific competition also had strong effects, reducing low-density tiller growth rates and aboveground biomass production for all three species. In fact, in the presence of competitors, (log tiller growth rates were close to or below zero for all three species. However, we found no convincing evidence that per capita competitive effects changed with precipitation, as shown by a lack of significant precipitation x competition interactions.We found little evidence that altered precipitation will influence per capita competitive effects. However, based on species' very low growth rates in the presence of competitors in some precipitation treatments, interspecific interactions appear strong enough to affect the balance between population persistence and local extinction. Therefore, ecological forecasting models should include the effect of interspecific interactions on population growth, even if such interaction coefficients are treated as constants.

Expression of future prospective in indirect speech

Directory of Open Access Journals (Sweden)

Bodnaruk Elena Vladimirovna

2015-03-01

Full Text Available The article analyzes the characteristics and use of grammatical semantics and lexical and grammatical means used to create future prospects in double indirect discourse. The material for the study were epic works by contemporary German writers. In the analysis of the empirical material it has been pointed out that indirect discourse has preterial basis and is the kind of most frequent inner speech of characters. The most widely used form with future semantics in preterial indirect speech is conditional I, formally having a conjunctive basis, but is mostly used with the indicative semantics. Competitive to conditional I in indirect speech is preterial indicative. A characteristic feature of the indirect speech is the use of modal verbs, which, thanks to its semantics is usually referred as an action at a later term, creating the prospect of future statements. The most frequent were modal verbs wollen and sollen in the form of the preterite, more rare verbs were m ssen and k nnen. German indirect speech distinguishes the ability to use forms on the basis of conjunctive: preterite and plusquamperfect of conjunctive. Both forms express values similar to those of the indicative. However, conjunctive forms the basis of the data shown in a slightly more pronounced seme of uncertainty that accompanies future uses of these forms in indirect speech. In addition, plusquamperfect conjunctive differs from others by the presence of the seme of completeness.

Interspecific interactions in phytophagous insects revisited: a quantitative assessment of competition theory.

Science.gov (United States)

Kaplan, Ian; Denno, Robert F

2007-10-01

The importance of interspecific competition is a highly controversial and unresolved issue for community ecology in general, and for phytophagous insects in particular. Recent advancements, however, in our understanding of indirect (plant- and enemy-mediated) interactions challenge the historical paradigms of competition. Thus, in the context of this rapidly developing field, we re-evaluate the evidence for interspecific competition in phytophagous insects using a meta-analysis of published studies. Our analysis is specifically designed to test the assumptions underlying traditional competition theory, namely that competitive interactions are symmetrical, necessitate spatial and temporal co-occurrence, and increase in intensity as the density, phylogenetic similarity, and niche overlap of competing species increase. Despite finding frequent evidence for competition, we found very little evidence that plant-feeding insects conform to theoretical predictions for interspecific competition. Interactions were highly asymmetrical, similar in magnitude within vs. between feeding guilds (chewers vs. sap-feeders), and were unaffected by the quantity of resources removed (% defoliation). There was mixed support for the effects of phylogeny, spatial/temporal separation, and the relative strength of intra- vs. interspecific competition. Clearly, a new paradigm that accounts for indirect interactions and facilitation is required to describe how interspecific competition contributes to the organization of phytophagous insect communities, and perhaps to other plant and animal communities as well.

The principle of securing competition is one of the basic principles of the contract system in public procurement in the Russian Federation. The law on the contract system in procurement stipulates that the contract system in procurement is aimed at creating equal conditions to ensure competition between the parties to procurement. An important aspect is that the competition for procurement should be based on compliance with the principle of fair price and non-price competition. The purpose o...

Coal is the most abundant domestic energy resource in the United States. The Fossil Energy Organization within the US Department of Energy (DOE) has been supporting a coal liquefaction program to develop improved technologies to convert coal to clean and cost-effective liquid fuels to complement the dwindling supply of domestic petroleum crude. The goal of this program is to produce coal liquids that are competitive with crude at $20 to $25 per barrel. Indirect and direct liquefaction routes are the two technologies being pursued under the DOE coal liquefaction program. This paper will give an overview of the DOE indirect liquefaction program. More detailed discussions will be given to the F-T diesel and DME fuels which have shown great promises as clean burning alternative diesel fuels. The authors also will briefly discuss the economics of indirect liquefaction and the hurdles and opportunities for the early commercial deployment of these technologies. Discussions will be preceded by two brief reviews on the liquid versus gas phase reactors and the natural gas versus coal based indirect liquefaction.

Full Text Available The purpose of this research is methodological bases improving and forming of practical tools for enterprise competitiveness management under the crisis. The specific features of the competitive environment of enterprises in Ukraine under the global and national crisis are researched in the article. From this it is concluded that any enterprise must have a greater degree of flexibility than in periods of stability or economic growth for obtaining and maintaining of competitive advantages in the current period of global instability. Flexibility and adaptability of the economic system is the main prerequisite for obtaining and developing of enterprise competitive advantages and stem component of competitiveness. We identified and characterized the methodological components of adaptive management process on the base of systematic approach and with taking into account views of scientists. The obtained scientific results are the basis for conceptual model of integrated system of enterprise adaptive management in terms of dynamic and uncertainty environment. We propose to implement this kind of control on three levels: strategic (preventive management, functionality (tactical management and operational (symptomatic management on the base of analyzing economically grounded views and existing positions. It all together will ensure effective adaptation at the macroeconomic, meso and micro levels of management. The main purpose of the proposed integrated management system is ensuring the stability and integrity of enterprises activity in terms of variability and uncertainty of the environment. The implementation of such management system provides the enterprise with certain competitive advantages. It will allow to Ukrainian enterprises maintaining the competitive position in unfavorable external conditions, but also maintaining and improving the competitiveness.

Mixing, entropy and competition

International Nuclear Information System (INIS)

Klimenko, A Y

2012-01-01

Non-traditional thermodynamics, applied to random behaviour associated with turbulence, mixing and competition, is reviewed and analysed. Competitive mixing represents a general framework for the study of generic properties of competitive systems and can be used to model a wide class of non-equilibrium phenomena ranging from turbulent premixed flames and invasion waves to complex competitive systems. We demonstrate consistency of the general principles of competition with thermodynamic description, review and analyse the related entropy concepts and introduce the corresponding competitive H-theorem. A competitive system can be characterized by a thermodynamic quantity—competitive potential—which determines the likely direction of evolution of the system. Contested resources tend to move between systems from lower to higher values of the competitive potential. There is, however, an important difference between conventional thermodynamics and competitive thermodynamics. While conventional thermodynamics is constrained by its zeroth law and is fundamentally transitive, the transitivity of competitive thermodynamics depends on the transitivity of the competition rules. Intransitivities are common in the real world and are responsible for complex behaviour in competitive systems. This work follows ideas and methods that have originated from the analysis of turbulent combustion, but reviews a much broader scope of issues linked to mixing and competition, including thermodynamic characterization of complex competitive systems with self-organization. The approach presented here is interdisciplinary and is addressed to the general educated readers, whereas the mathematical details can be found in the appendices. (comment)

2011-10-01

Full Text Available Abstract Background Botrytis cinerea is a phytopathogenic fungus responsible for the disease known as gray mold, which causes substantial losses of fruits at postharvest. This fungus is present often as latent infection and an apparently healthy fruit can deteriorate suddenly due to the development of this infection. For this reason, rapid and sensitive methods are necessary for its detection and quantification. This article describes the development of an indirect competitive enzyme-linked immunosorbent assay (ELISA for quantification of B. cinerea in apple (Red Delicious, table grape (pink Moscatel, and pear (William's tissues. Results The method was based in the competition for the binding site of monoclonal antibodies between B. cinerea antigens present in fruit tissues and B. cinerea purified antigens immobilized by a crosslinking agent onto the surface of the microtiter plates. The method was validated considering parameters such as selectivity, linearity, precision, accuracy and sensibility. The calculated detection limit was 0.97 μg mL-1 B. cinerea antigens. The immobilized antigen was perfectly stable for at least 4 months assuring the reproducibility of the assay. The fungus was detected and quantified in any of the fruits tested when the rot was not visible yet. Results were compared with a DNA quantification method and these studies showed good correlation. Conclusions The developed method allowed detects the presence of B. cinerea in asymptomatic fruits and provides the advantages of low cost, easy operation, and short analysis time determination for its possible application in the phytosanitary programs of the fruit industry worldwide.

Hostile sexism (de)motivates women's social competition intentions: The contradictory role of emotions.

Lemonaki, Elena; Manstead, Antony S R; Maio, Gregory R

2015-09-01

In the present research, we examine the ways in which exposure to hostile sexism influences women's competitive collective action intentions. Prior to testing our main model, our first study experimentally induced high versus low levels of security-comfort with the aim of providing experimental evidence for the proposed causal link between these emotions and intentions to engage in social competition. Results showed that lower levels of security-comfort reduced women's readiness to compete socially with men. Experiment 2 investigated the effect of hostile sexism on women's emotional reactions and readiness to engage in social competition. Consistent with the proposed model, results showed that exposure to hostile beliefs about women (1) increased anger-frustration and (2) decreased security-comfort. More specifically, exposure to hostile sexism had a positive indirect effect on social competition intentions through anger-frustration, and a negative indirect effect through security-comfort. © 2015 The British Psychological Society.

Marginal cost and congestion in the Italian electricity market: An indirect estimation approach

International Nuclear Information System (INIS)

Bigerna, Simona; Andrea Bollino, Carlo; Polinori, Paolo

2015-01-01

In this paper we construct an indirect measure of the supply marginal cost function for the main generators from the observed bid data in the Italian electricity market in the period 2004–2007. We compute the residual demand function for each generator, taking explicitly into account the issue of transmission line congestion. This procedure allows recovering correct zonal Lerner index and the implied measure of the marginal cost function. We find evidence of a stable U-shaped marginal cost function for three main Italian generators, but a flat function for ENEL, the former national monopolist. The policy relevance of our approach lies in the possibility to offer some empirical knowledge of the marginal cost function of each generator to the regulator to design appropriate policy measures geared to the promotion of competitive market conditions. We propose a new market surveillance mechanism, which is based on the principle of sanctioning excessive deviations from the estimated measure of the marginal cost function presented in this work. -- Highlights: •We construct an indirect measure of the supply marginal cost function. •We compute the residual demand function taking into account transmission line congestion. •We find a general evidence of a stable U-shaped marginal cost function for Italian generators. •We find flat marginal cost function for the former national monopolist. •We use excessive deviations from estimated marginal cost function as a new market surveillance mechanism

Indirect reciprocity in three types of social dilemmas.

Nakamura, Mitsuhiro; Ohtsuki, Hisashi

Indirect reciprocity is a key mechanism for the evolution of human cooperation. Previous studies explored indirect reciprocity in the so-called donation game, a special class of Prisoner's Dilemma (PD) with unilateral decision making. A more general class of social dilemmas includes Snowdrift (SG), Stag Hunt (SH), and PD games, where two players perform actions simultaneously. In these simultaneous-move games, moral assessments need to be more complex; for example, how should we evaluate defection against an ill-reputed, but now cooperative, player? We examined indirect reciprocity in the three social dilemmas and identified twelve successful social norms for moral assessments. These successful norms have different principles in different dilemmas for suppressing cheaters. To suppress defectors, any defection against good players is prohibited in SG and PD, whereas defection against good players may be allowed in SH. To suppress unconditional cooperators, who help anyone and thereby indirectly contribute to jeopardizing indirect reciprocity, we found two mechanisms: indiscrimination between actions toward bad players (feasible in SG and PD) or punishment for cooperation with bad players (effective in any social dilemma). Moreover, we discovered that social norms that unfairly favor reciprocators enhance robustness of cooperation in SH, whereby reciprocators never lose their good reputation.

The monitoring of salivary cortisol as a key biomarker of an individual’s stress response has been increasingly focused on. This paper describes the development of a novel cortisol immuno-assay method based on an indirect competitive method using a commercially available surface plasmon resonance instrument. The surface of an Au chip was modified with PEG6-COOH aromatic dialkanethiol self-assembled monolayers and hydrocortisone 3-(O-carboxymethyl) oxime (hydrocortisone 3-CMO) as a cortisol analog. A detection limit of 38 ppt range with a measurement range of 10 ppt–100 ppb was accomplished without the incubation of a mixing solution consisting of standard cortisol and an anti-cortisol antibody, and the time for quantification of cortisol concentration was 8 min from the sample injection. We experimentally compared our immuno-assay with a commercialized salivary cortisol enzyme-linked immunosorbent assay (ELISA) kit using human saliva samples. It was found that the results obtained by the cortisol immuno-assay had a good correlation with those obtained by ELISA assay (R = 0.96). Our findings indicate the potential utility of the cortisol immuno-assay for measurements of human salivary cortisol levels.

This document discusses various issues associated with the planned competitive call on the French hydraulic power plants. The principles of this competitive call for hydroelectric concessions are first addressed: administrative regime of concessions, competitive call process, criteria of selection of the concession holder, case of 'concession of valleys', potential competitors. It outlines and discusses the difficulties of this competitive call: France is the single country to implement this procedure; it concerns a national asset; it questions the guarantee of a future use of equipment at best for the energy benefits of French consumers; the competitive call is a nice idea indeed but extremely complex.

Indirect evolution of social fitness inequalities and facultative social exploitation.

Science.gov (United States)

Nair, Ramith R; Fiegna, Francesca; Velicer, Gregory J

2018-03-28

Microbial genotypes with similarly high proficiency at a cooperative behaviour in genetically pure groups often exhibit fitness inequalities caused by social interaction in mixed groups. Winning competitors in this scenario have been referred to as 'cheaters' in some studies. Such interaction-specific fitness inequalities, as well as social exploitation (in which interaction between genotypes increases absolute fitness), might evolve due to selection for competitiveness at the focal behaviour or might arise non-adaptively due to pleiotropy, hitchhiking or genetic drift. The bacterium Myxococcus xanthus sporulates during cooperative development of multicellular fruiting bodies. Using M. xanthus lineages that underwent experimental evolution in allopatry without selection on sporulation, we demonstrate that interaction-specific fitness inequalities and facultative social exploitation during development readily evolved indirectly among descendant lineages. Fitness inequalities between evolved genotypes were not caused by divergence in developmental speed, as faster-developing strains were not over-represented among competition winners. In competitions between ancestors and several evolved strains, all evolved genotypes produced more spores than the ancestors, including losers of evolved-versus-evolved competitions, indicating that adaptation in non-developmental contexts pleiotropically increased competitiveness for spore production. Overall, our results suggest that fitness inequalities caused by social interaction during cooperative processes may often evolve non-adaptively in natural populations. © 2018 The Authors.

From Hitting to Tattling to Gossip: An Evolutionary Rationale for the Development of Indirect Aggression

Directory of Open Access Journals (Sweden)

Gordon P. D. Ingram

2014-04-01

Full Text Available Adult humans are characterized by low rates of intra-group physical aggression. Since children tend to be more physically aggressive, an evolutionary developmental account shows promise for explaining how physical aggression is suppressed in adults. I argue that this is achieved partly through extended dominance hierarchies, based on indirect reciprocity and linguistic transmission of reputational information, mediated by indirectly aggressive competition. Reviewing the literature on indirect and related forms of aggression provides three pieces of evidence for the claim that evolutionarily old impulses towards physical aggression are socialized into indirect aggression in humans: (i physical aggression falls in early childhood over the same age range at which indirect aggression increases; (ii the same individuals engage in both direct and indirect aggression; and (iii socially dominant individuals practice indirect aggression more frequently. Consideration of the developmental course of indirect aggression is complemented by analysis of similar developments in verbal behaviors that are not always thought of as aggressive, namely tattling and gossip. An important puzzle concerns why indirect aggression becomes more covert, and tattling more derogated, in preadolescence and adolescence. This may be due to the development of new strategies aimed at renegotiating social identity and friendship alliances in the peer group.

Full Text Available Received trade theory presumes an important role for increasing returns to scale, product-differentiation, and quality as determinants of trade flows. In a global world, exports can only be expanded if a nation is competitive in terms of cost and quality of traded products. Food safety and quality systems, such as HACCP or ISO 9000, are indirectly included in international agreements (GATT as facilitators of trade. These systems may lead to cost leadership and product improvement, which are key factors to higher competitiveness and sustained benefits in international markets. This paper estimates a modified Armington model that links product differentiation and safety programs to market shares, i.e. competitiveness.

Resource competition and an analytical model of zooplankton feeding on phytoplankton

1975-01-01

A new consumer-resource The model was developed with specific reference to zooplankton feeding on phytoplankton. In principle, the model can be extended to any terrestrial or aquatic community in which the consumers graze nearly randomly. It is assumed that the food as relatively little escape capabity. An attempt was made to derive the consumer-resource interaction term from first principles.A general form with clearly defined parameters that represent fundamental system processes such as consumer filtering rate. model parameters describes two known forms of feeding:(1): saturation feeding in which the rate remains constant above a given food density while the filtering rate decreases, and(2) inhibited feeding in which a decline appears at high food density. From an examination of the model's equilibrium equations for strongly similar zooplankton species feeding on similar phytoplankton species, the following conclusions were drawn. The competitive exclusion principle has only limited validity. For a community in which the consumers exhibit no intraspecific competition and have identical assimilation efficiency to death-rate ratios, e/d, any number of consumer species may, in fact, coexist and compete for the same food. The equations for a complex community composed of many consumer and food species can be reduced to a single equation with form identical to that of a single-consumer, single-food system. The standard competition coefficient, ..cap alpha.., of the Volterra equation is a poor measure of competition in nonlinear systems. It exhibits incongruous variations with changes in system parameters. In a community with no intraspecific competition, allcompetition coefficients are unity. In a community with intraspecific competition, the competition coefficients C/sub in/ tend to equalize as the number of food species increases, resulting in equal competitive strength of all consumer species in systems of the type studied.

While accepted in theory and practice that an obligation to supply, ser-vice or license can emerge under competition law, the scope of this is subject to many, if not lacunas, at least ambiguities, and no general ob-li¬gations of such nature can, no should, be identified. Further, and equally...... important, the narrow set of circumstances warranting inter-vention against refusals is defined by competition law in accordance with its underlying principles of a predominantly economic nature. Hence, competition law should not be relied upon as a corrective in-strument to lacunas in other areas of law, e.......g. compulsory licenses un-der IP law.

In intrasexual competition (competition for reproductive resources), bullying can be viewed as a tool to devalue competitors, gain a high status and a powerful, dominant position in the peer group which may lead to beneficial gains such as access to potential romantic partners. This study investigated the relationship between intrasexual competition, bullying victimization and body-esteem, in single-sex versus mixed-sex schools. 420 participants completed a body-esteem scale, a retrospective bullying questionnaire, and intrasexual competition scales. Our results showed that relational victimization was associated with low body-esteem for both females and males. Females in single-sex schools experienced higher intrasexual competition which in turn was associated with their body-esteem directly and indirectly via relational victimization. In males, intrasexual competition was indirectly associated with body-esteem via relational victimization. Interventions to improve body esteem may focus on reducing intrasexual competition and peer victimization. Copyright © 2014 The Foundation for Professionals in Services for Adolescents.

2016-07-01

Full Text Available 1990’s world was quite different from the world of 1950’s. Especially in the last twenty years, the increasing involvement of Japan in the world economy since the 1990s, in addition to the dominance of globalization and market economy throughout the world, the rapid spread of information resulting from the developments in IT-technology and the international competition emerging in the field of technology have all led to some significant developments in the world economy. Reduction of high mobility income and corporate tax rates due to tax competition may cause an unjust distribution of the tax burden. The fact that indirect taxation constitutes about 70% of the tax revenues obtained in Turkey can be taken as an indication of the unfairness in the distribution of tax burden in Turkey. In this study, following a definition of globalization and tax competition, classification of tax competition, reasons for increasing tax competition, benefits and losses of tax competition are explained, and changes introduced by various countries in their tax systems due to tax competition, the distribution of tax burden resulting from tax competition in Turkey and the effectiveness of the new income tax law in Turkey in terms of tax competition are analyzed.

While exciting times of opportunity are again ahead for the nuclear industry, the excitement has to consider that there are differences between general nuclear and general commerce. These differences are driven by some fundamental principles that impact nuclear reactor operation and examples are given of how these principles must be protected to ensure that nuclear generation can be of continued benefit to the public.

2001-01-01

As of August 1 last year, Finland's Electricity Market Authority became the Energy Market Authority. The timing of the change coincided with the introduction of Finland's new Natural Gas Market Act and reflected the extension of the Authority's responsibility to cover promoting healthy and efficient competition on both the electricity and natural gas market and to secure reasonable and equitable service principles in the operations of both networks. The Electricity Market Authority began operations in mid-1995 as an expert body subordinate to the Ministry of Trade and industry when Finland's Electricity Market Act came into force, bringing with it a phased opening-up of the Finnish electricity market. The principle task of the Authority was, and remains, to supervise the pricing of transmission, distribution, and other network services, and to ensure a healthy level of competition

On the one hand, the optimal deterministic strategy and its competitive ratio are obtained; on the other hand, a nearly optimal randomized strategy is constructed and a lower bound for the randomized competitive ratios is proved by Yao's principle. With the help of numerical examples, the theoretical results show that the interest rate pu...

Principle of least action; some possible generalizations

International Nuclear Information System (INIS)

Broucke, R.

1982-01-01

In this article we draw the attention to an important variational principle in dynamics: the Maupertuis-Jacobi Least Action Principle (MJLAP). This principle compares varied paths with the same energy h. We give two new proofs of the MJLAP (Sections 3 and 8) as well as a new unified variational principle which contains both Hamilton's Principle (HP) and the MJLAP as particular cases (Sections 4 and 9). The article also shows several new methods for the construction of a Lagrangian for a conservative dynamical system. As an example, we illustrate the theory with the classical Harmonic Oscillator Problem (Section 10). Our method is based on the theory of changes of independent variables in a dynamical system. It indirectly shows how a change of independent variable affects the self-adjointness of a dynamical system (Sections 5, 6, 7). Our new Lagrangians contain an arbitrary constant α, whose meaning needs to be studied, eventually in relation to the concepts of quantification or gauge transformations. The two important values of the constant α are 1 (Hamilton's principle) and 1/2 (Maupertuis-Jacobi Least Action Principle)

This paper applies the Lotka–Volterra model to investigate the competitive interactions among energy, environment, and economy (3Es) in the U.S. The proposed LV-COMSUD (Lotka–Volterra COmpetition Model for SUstainable Development) has satisfactory performance for model fitting and provides a useful multivariate framework to predict outcomes concerning these interactions. Our key findings include a pure competition between emissions and GDP (Gross Domestic Product), neutralisms between renewable and fossil/nuclear energy, and commensalisms between GDP and renewable/fossil energy and between nuclear energy and fossil energy/emissions. These results indicate that renewable/fossil energy use contributes to GDP and interacts indirectly with emissions, that an environmental Kuznets curve exists, and that the amount of produced nuclear energy correlates with emission. The U.S. is dependent on non-clean energy sources and its energy efficiency has room for improvement. The results provide unique insights for policy makers to craft up sustainable economic development plans. Overall, it is suggested that for developed markets such as the U.S., to enhance energy security and mitigate climate changes, improving energy efficiency and developing low-carbon clean energy should be top priorities. - Highlights: • The competitive interactions among energy, environment, and economy are examined. • A pure competition between emissions and GDP exists and an EKC exists. • Energy use contributes to GDP and interacts indirectly with emissions. • Nuclear energy was used to tackle the growth of emissions/fossil energy use. • Improved energy efficiency is a viable policy to enhance energy security in U.S

Leaderboards provide feedback on relative performance and a competitive atmosphere for both self-guided improvement and social comparison. Because simulation can provide substantial quantitative participant feedback, leaderboards can be used, not only locally but also in a multidepartment, multicenter fashion. Quick Response (QR) codes can be integrated to allow participants to access and upload data. We present the development, implementation, and initial evaluation of an online leaderboard employing principles of gamification using points, badges, and leaderboards designed to enhance competition among healthcare providers. This article details the fundamentals behind the development and implementation of a user-friendly, online, multinational leaderboard that employs principles of gamification to enhance competition and integrates a QR code system to promote both self-reporting of performance data and data integrity. An open-ended survey was administered to capture perceptions of leaderboard implementation. Conceptual step-by-step instructions detailing how to apply the QR code system to any leaderboard using simulated or real performance metrics are outlined using an illustrative example of a leaderboard that employed simulated cardiopulmonary resuscitation performance scores to compare participants across 17 hospitals in 4 countries for 16 months. The following three major descriptive categories that captured perceptions of leaderboard implementation emerged from initial evaluation data from 10 sites: (1) competition, (2) longevity, and (3) perceived deficits. A well-designed leaderboard should be user-friendly and encompass best practices in gamification principles while collecting and storing data for research analyses. Easy storage and export of data allow for longitudinal record keeping that can be leveraged both to track compliance and to enable social competition.

Trait and perceived environmental competitiveness in achievement situations.

Elliot, Andrew J; Jury, Mickaël; Murayama, Kou

Trait and perceived environmental competitiveness are typically studied separately, but they undoubtedly have a joint influence on goal pursuit and behavior in achievement situations. The present research was designed to study them together. We tested the relation between trait and perceived environmental competitiveness, and we tested these variables as separate and sequential predictors of both performance-based goals and performance attainment. In Studies 1a (N = 387 U.S. undergraduates) and 1b (N = 322 U.S. undergraduates), we assessed participants' trait and perceived environmental competitiveness, as well as third variable candidates. In Study 2 (N = 434 MTurk workers), we sought to replicate and extend Study 1 by adding reports of performance-based goal pursuit. In Study 3 (N = 403 U.S. undergraduates), we sought to replicate and extend Study 2 by adding real-world performance attainment. The studies focused on both the classroom and the workplace. Trait and perceived environmental competitiveness were shown to be positively related and to positively predict separate variance in performance-approach and performance-avoidance goal pursuit. Perceived environmental competitiveness and performance-based goal pursuit were shown to be sequential mediators of the indirect relation between trait competitiveness and performance attainment. These studies highlight the importance of attending to the interplay of the person and the (perceived) situation in analyses of competitive striving. © 2017 Wiley Periodicals, Inc.

Direct observation of the lowest indirect exciton state in the bulk of hexagonal boron nitride

Science.gov (United States)

Schuster, R.; Habenicht, C.; Ahmad, M.; Knupfer, M.; Büchner, B.

2018-01-01

We combine electron energy-loss spectroscopy and first-principles calculations based on density-functional theory (DFT) to identify the lowest indirect exciton state in the in-plane charge response of hexagonal boron nitride (h-BN) single crystals. This remarkably sharp mode forms a narrow pocket with a dispersion bandwidth of ˜100 meV and, as we argue based on a comparison to our DFT calculations, is predominantly polarized along the Γ K direction of the hexagonal Brillouin zone. Our data support the recent report by Cassabois et al. [Nat. Photonics 10, 262 (2016), 10.1038/nphoton.2015.277] who indirectly inferred the existence of this mode from the photoluminescence signal, thereby establishing h-BN as an indirect semiconductor.

Interactions between freshwater snails and tadpoles: competition and facilitation.

Science.gov (United States)

Brönmark, Christer; Rundle, Simon D; Erlandsson, Ann

1991-06-01

Freshwater snails and anuran tadpoles have been suggested to have their highest population densities in ponds of intermediate size where abiotic disturbance (e.g. desiccation) is low and large predators absent. Both snails and tadpoles feed on periphytic algae and, thus, there should be a large potential for competitive interactions to occur between these two distantly related taxa. In a field experiment we examined the relative strength of competition between two closely related snail species, Lymnaea stagnalis and L. peregra, and between L. stagnalis and tadpoles of the common frog, Rana temporaria. Snail growth and egg production and tadpole size at and time to metamorphosis were determined. Effects on the common food source, periphyton, were monitored with the aid of artificial substrates. Periphyton dry weight was dramatically reduced in the presence of snails and/or tadpoles. There were no competitive effects on growth or egg production of the two snail species when they were coexisting. Mortality of L. peregra was high (95%) after reproduction, but independent of treatment. Growth of L. stagnalis was reduced only at the highest tadpole densities, whereas egg production was reduced both by intraspecific competition and by competition with tadpoles. Differences in egg production were retained after tadpole metamorphosis. Tadpole larval period increased, weight of metamorphosing frogs decreased and growth rate was reduced as a function of increasing tadpole density. However, contrary to expectation, snails had a positive effect on tadpole larval period, weight and growth rate. Further, in experimental containers without snails there was a dense growth of the filamentous green alga Cladophora sp. We suggest that the facilitative effects of snails on tadpoles are due to an "indirect mutualistic" mechanism, involving competition between food sources of different quality (microalgae and Cladophora sp.) and tadpoles being competitively dominant over snails for the

Full Text Available Background: Whilst there are separate streams of established research on lean, green and best practice initiatives, the intersection of these three strategic principles has not been addressed extensively in the past. Objectives: In this study a framework to integrate lean, green and best practice principles into an integrated business model was developed as a strategy for businesses to develop sustainable competitive advantages. Method: A descriptive case study was conducted on Toyota South Africa Motors (TSAM to understand whether a clear link between the company’s environmental approach, lean principles and established best practice culture could be determined. In addition, the case study tested the view that the implementation of these three principles concurrently resulted in improved business results. Results: The main findings of the study revealed that TSAM’s commitment to lean, green and best practice business principles contributed and was directly linked to its business success in terms of sales and market position. Conclusion: It is recommended that businesses implement an integrated lean, green and best practice business model as a strategy to reduce costs and sustainably enhance profitably and competitiveness.

The purpose of this study was to evaluate the performance of a competitive ELISA system for the diagnosis of bovine brucellosis in comparison to conventional aerological tests routinely used in Argentina. A total of 2.500 serum samples, comprising Brucella-free herds, vaccinated cattle and naturally infected animals, was tested by the following tests: buffered plate agglutination, Rose Bengal, 2-mercaptoethanol, complement fixation, and indirect and competitive ELISAs. Specificity and relative sensitivity at each test were determined. The competitive ELISA was considered suitable for detection of vaccinated animals and had higher specificity than the other tests. The results point to the potential use of the test as a complementary assay in the brucellosis control programme in Argentina. (author)

2014-01-01

This paper studies the aggregate substitution and expansion effects triggered by changes in input prices in a context where firms supply a homogeneous commodity and compete in quantities à la Cournot. We derive a sufficient condition for the existence of a Cournot equilibrium and show that this condition also ensures that the Le Chatelier-Samuelson principle is satisfied in the aggregate at the Cournot equilibrium, although it may not be satisfied at the firm level.

Resource competition in plant invasions: emerging patterns and research needs.

Science.gov (United States)

Gioria, Margherita; Osborne, Bruce A

2014-01-01

Invasions by alien plants provide a unique opportunity to examine competitive interactions among plants. While resource competition has long been regarded as a major mechanism responsible for successful invasions, given a well-known capacity for many invaders to become dominant and reduce plant diversity in the invaded communities, few studies have measured resource competition directly or have assessed its importance relative to that of other mechanisms, at different stages of an invasion process. Here, we review evidence comparing the competitive ability of invasive species vs. that of co-occurring native plants, along a range of environmental gradients, showing that many invasive species have a superior competitive ability over native species, although invasive congeners are not necessarily competitively superior over native congeners, nor are alien dominants are better competitors than native dominants. We discuss how the outcomes of competition depend on a number of factors, such as the heterogeneous distribution of resources, the stage of the invasion process, as well as phenotypic plasticity and evolutionary adaptation, which may result in increased or decreased competitive ability in both invasive and native species. Competitive advantages of invasive species over natives are often transient and only important at the early stages of an invasion process. It remains unclear how important resource competition is relative to other mechanisms (competition avoidance via phenological differences, niche differentiation in space associated with phylogenetic distance, recruitment and dispersal limitation, indirect competition, and allelopathy). Finally, we identify the conceptual and methodological issues characterizing competition studies in plant invasions, and we discuss future research needs, including examination of resource competition dynamics and the impact of global environmental change on competitive interactions between invasive and native species.

1998-01-01

In order to contribute to the definition of the best ELISA test for screening and differential diagnosis of Brucella abortus to be applied for control programmes, a total of 2971 sera from Colombian cattle were tested for brucellosis. Conventional agglutination tests, Buffered Plate antigen test (BPAT) and Rose Bengal (RB) as well as Complement Fixation test (CFT) (Alton, et al. 1988) were used comparatively. Radial immunodiffusion test (RID) was also performed to all sera. The sera were also tested using four different ELISAs: indirect ELISA from FAO/IAEA and the indirect ELISA modified by Nielsen, et al. 1992 as well as two competitive ELISAs: one competitive ELISA used B. abortus O-polysaccharide antigen and an enzyme conjugated monoclonal to the O-polysaccharide for competition and detection. The second competitive ELISA used lipopolysaccharide (sLPS) antigen, a different monoclonal antibody for competition but also specific for the O-polysaccharide and a commercially available goat anti-mouse IgG enzyme conjugate for detection. The sera were analyzed based on its population status, 987 positive obtained from Brucella abortus infected herds based on clinical and/or bacteriological evidence and a high prevalence of brucellosis, CFT percentage of positive animals in the herd was greater than 5%. Eight hundred sixty six (866) negative sera from non-vaccinated cattle from a brucellosis free area and 1118 negative sera obtained from reglamentary vaccinated areas under a free herd program. Initial cut-off values were derived using negative serum samples. The diagnostic sensitivity and specificity was defined from frequency histograms based on this cut-off values and using 2x2 tables, corresponding confidence limits (95%) were calculated. The data were also analysed using signal detection analysis (ROC). Kappa statistics was determined for all tests and populations, accuracy was used as index of comparison to evaluate different assays. The data support the initial

Folkins, John Wm; Brackenbury, Tim; Krause, Miriam; Haviland, Allison

2016-02-01

This article considers the potential benefits that applying design principles from contemporary video games may have on enhancing therapy experiences. Six principles of video game design are presented, and their relevance for enriching clinical experiences is discussed. The motivational and learning benefits of each design principle have been discussed in the education literature as having positive impacts on student motivation and learning and are related here to aspects of clinical practice. The essential experience principle suggests connecting all aspects of the experience around a central emotion or cognitive connection. The discovery principle promotes indirect learning in focused environments. The risk-taking principle addresses the uncertainties clients face when attempting newly learned skills in novel situations. The generalization principle encourages multiple opportunities for skill transfer. The reward system principle directly relates to the scaffolding of frequent and varied feedback in treatment. Last, the identity principle can assist clients in using their newly learned communication skills to redefine self-perceptions. These principles highlight areas for research and interventions that may be used to reinforce or advance current practice.

The shape, speed and direction of further reforms in Alberta's electric power industry were forecast, following the introduction of a competitive framework for the industry, the first province to do so in Canada, effective January 1996. This study reviews the previously existing system ( a mix of investor-owned and municipally-owned utilities), as well as the proposed new structure as laid out in the new Electric Utilities Act, based on the three principles of unbundling, a competitive power pool and open system access transmission. The paper also reviewed some of the major issues that will have to be faced in the future, such as how to deal with market power and possible collusion between the generators to hold prices down, a problem that has been the well-known failing of the U.K. pool mechanism

Infectious diseases in competitive sports.

Science.gov (United States)

Goodman, R A; Thacker, S B; Solomon, S L; Osterholm, M T; Hughes, J M

1994-03-16

Participation in competitive sports is popular and widely encouraged throughout the United States. Reports of infectious disease outbreaks among competitive athletes and recent publicity regarding infectious disease concerns in sports underscore the need to better characterize the occurrence of these problems. To identify reports of infectious diseases in sports, we performed a comprehensive search of the medical literature (MEDLINE) and newspaper databases in two on-line services (NEXIS and DIALOG PAPERS). Articles selected from the literature review included those describing cases or outbreaks of disease in which exposure to an infectious agent was likely to have occurred during training for competitive sports or during actual competition. Articles from the newspaper review included reports of outbreaks, exposures, or preventive measures that directly or indirectly involved teams or spectators. The literature review identified 38 reports of infectious disease outbreaks or other instances of transmission through person-to-person (24 reports), common-source (nine reports), or airborne (five reports) routes; the newspaper search identified 28 reports. Infectious agents included predominantly viruses but also a variety of fungi and gram-positive and gram-negative bacteria. Our findings indicate that strategies to prevent transmission of infectious diseases in sports must recognize risks at three levels: the individual athlete, the team, and spectators or others who may become exposed to infectious diseases as a result of sports-related activities. Team physicians and others who are responsible for the health of athletes should be especially familiar with the features of infectious diseases that occur in sports and measures for the prevention of these problems.

Full Text Available The purpose of the article is to investigate the current state of scientific thought in relation to the formation of intellectual capital of an enterprise in the innovation process, achievement by the enterprise of corresponding competitive advantages and their protection. Methodology. The methodological basis of the article is the systematic approach, which provided a comprehensive definition of the scope of this research – intellectual property and its protection as a complex economic and legal category. This made it possible to systematically define the purpose, level of abstraction, hierarchy, forms of manifestation, and key attributes of the subject of research. Application of principles of modelling of business processes also allowed studying the influence of factors of the external environment on the sequence of information flows in the process of forming competitive advantages on the basis of intellectual property. In addition, having determined the scientific basis, the collective and local monographic studies of leading scientists concerning the specificity of the formation of competitive advantages of innovative enterprises, including on the basis of intellectual capital, were also taken into account. Results. The article studies, describes and, correspondingly, formalizes modern processes of formation of competitive advantages in the conditions of Smart Economy: knowledge management, their patenting, modern significance, and the influence of patenting on the role of intellectual property in the investigated phenomena, as well as management of relevant information flows. Practical implications. The research demonstrates ways of forming competitive advantages in the modern economy, and the results of the analysis of relevant statistics explain patterns of economic and legal processes in the field of relevant practical activities. This allows assessing the actual state of the subject of the research, determining the development

Here, we unraveled the shear-induced direct-to-indirect gap transition and anisotropy diminution in phosphorene based on first-principles calculations. Lattice dynamic analysis demonstrates that phosphorene can sustain up to 10% applied shear strain. The bandgap of phosphorene experiences a direct-to- indirect transition when 5% shear strain is applied. The electronic origin of the direct-to-indirect gap transition from 1.54 eV at ambient conditions to 1.22 eV at 10% shear strain for phosphorene is explored. In addition, the anisotropy diminution in phosphorene is discussed by calculating the maximum sound velocities, effective mass, and decomposed charge density, which signals the undesired shear-induced direct-to-indirect gap transition in applications of phosphorene for electronics and optoelectronics. On the other hand, the shear-induced electronic anisotropy properties suggest that phosphorene can be applied as the switcher in nanoelectronic applications.

Indirect measurements of X-ray spectra

International Nuclear Information System (INIS)

Mainardi, R.T.

2006-01-01

To the effects of measuring the spectral distribution of the radiation emitted by the x-ray tubes and electron accelerators, numerous procedures that are grouped in two big categories exist at the present time: direct and indirect methods. The first ones use high resolution detectors that should be positioned, together with the appropriate collimator, in the direction of the x ray beam. The user should be an expert in the use and correction of the obtained data by the different effects that affect the detector operation such as efficiency and resolution in terms of the energy of the detected radiation. The indirect procedures, although its are more simple to use, its also require a considerable space along the beam to position the ionization chamber and the necessary absorbents to construct by this way the denominated attenuation curve. We will analyze the operation principle of the indirect methods and a new proposal in which such important novelties are introduced as the beam dispersion to avoid to measure along the main beam and that of determination of the attenuation curve in simultaneous form. By this way, with a single shot of the tube, the attenuation curve is measured, being necessary at most a shot of additional calibration to know the relative response of the detectors used in the experimental array. The physical processes involved in the obtaining of an attenuation curve are very well well-known and this it finishes it can be theoretically calculated if the analytic form of the spectrum is supposed well-known. Finally, we will see a spectra reconstruction example with the Kramers parametric form and comparisons with numeric simulations carried out with broadly validated programs as well as the possibility of the use of solid state dosemeters in the obtention of the attenuation curve.

Active videogames have the potential to enhance population levels of physical activity but have not been successful in achieving this aim to date. This article considers a range of principles that may be important to the design of effective and efficient active videogames from diverse discipline areas, including behavioral sciences (health behavior change, motor learning, and serious games), business production (marketing and sales), and technology engineering and design (human-computer interaction/ergonomics and flow). Both direct and indirect pathways to impact on population levels of habitual physical activity are proposed, along with the concept of a game use lifecycle. Examples of current active and sedentary electronic games are used to understand how such principles may be applied. Furthermore, limitations of the current usage of theoretical principles are discussed. A suggested list of principles for best practice in active videogame design is proposed along with suggested research ideas to inform practice to enhance physical activity.

Indirection and computer security.

Energy Technology Data Exchange (ETDEWEB)

Berg, Michael J.

2011-09-01

The discipline of computer science is built on indirection. David Wheeler famously said, 'All problems in computer science can be solved by another layer of indirection. But that usually will create another problem'. We propose that every computer security vulnerability is yet another problem created by the indirections in system designs and that focusing on the indirections involved is a better way to design, evaluate, and compare security solutions. We are not proposing that indirection be avoided when solving problems, but that understanding the relationships between indirections and vulnerabilities is key to securing computer systems. Using this perspective, we analyze common vulnerabilities that plague our computer systems, consider the effectiveness of currently available security solutions, and propose several new security solutions.

Finding the best fit for direct and indirect causation: a typological study

Directory of Open Access Journals (Sweden)

Levshina Natalia

2016-12-01

Full Text Available The contrast between direct and indirect causation is the most widely discussed semantic distinction in the literature on causative constructions. This distinction has been claimed to correlate with a number of formal parameters, such as formal distance, productivity and length, which are linked to different functional and diachronic explanations based on the principles of iconicity and economy. The present study tests these claims on a typologically representative sample of languages from 46 diverse families, examining four formal variables and their association with (indirectness of causation. According to the data, formal length displays the most pervasive association with the semantic distinction in question, which supports the economy-based explanation. In addition, the relative prominence of the other formal parameters depends on the type of causatives and their stage of grammaticalization.

This paper presents a comparative techno-economic analysis of five conversion pathways from biomass to gasoline-, jet-, and diesel-range hydrocarbons via indirect liquefaction with specific focus on pathways utilizing oxygenated intermediates (derived either via thermochemical or biochemical conversion steps). The four emerging pathways of interest are compared with one conventional pathway (Fischer-Tropsch) for the production of the hydrocarbon blendstocks. The processing steps of the four emerging pathways include: biomass-to-syngas via indirect gasification, gas cleanup, conversion of syngas to alcohols/oxygenates, followed by conversion of alcohols/oxygenates to hydrocarbon blendstocks via dehydration, oligomerization, and hydrogenation. We show that the emerging pathways via oxygenated intermediates have the potential to be cost competitive with the conventional Fischer-Tropsch process. The evaluated pathways and the benchmark process generally exhibit similar fuel yields and carbon conversion efficiencies. The resulting minimum fuel selling prices are comparable to the benchmark at approximately $3.60 per gallon-gasoline equivalent, with potential for two new pathways to be more economically competitive. Additionally, the coproduct values can play an important role in the economics of the processes with oxygenated intermediates derived via syngas fermentation. Major cost drivers for the integrated processes are tied to achievable fuel yields and conversion efficiency of the intermediate steps, i.e., the production of oxygenates/alcohols from syngas and the conversion of oxygenates/alcohols to hydrocarbon fuels.

Evaluation of the radioimmunoassay, indirect enzyme linked immunosorbent assay, and dot blot assay for the identification of Xanthomonas campestris pv. phaseoli

A radioimmunoassay (RIA), an indirect competitive enzyme-linked immunosorbent assay (ELISA), and a dot-blot modification of the ELISA were evaluated for detection and identification of Xanthomonas campestris pv. phaseoli (X. c. pv. phaseoli). RIA and the dot blot tests were specific for X. c. pv. phaseoli; however, significant cross reactions occurred in the indirect competitive ELISA when using anti-X. c. pv. phaseoli antiserum against other closely related bacteria. The sensitivity level of all procedures for X. c. pv. phaseoli was approximately l0/sup 5/ colony forming unitsmL. All procedures were unsatisfactory in reliably detecting low levels of X. c. pv. phaseoli directly from extracts of bean seed. However when used in conjunction with ilution plating the dot blot assay and the RIA would be useful in specifically identifying X. c. pv. phaseoli. The relative merits of these tests for identification of X. c. pv. phaseoli are discussed.

Probiotics and the Gut Immune System: Indirect Regulation.

The gastrointestinal tract (GIT) represents the largest interface between the human organism and the external environment. In the lumen and upper part of the mucus layer, this organ hosts an enormous number of microorganisms whose composition affects the functions of the epithelial barrier and the gut immune system. Consequentially, the microorganisms in the GIT influence the health status of the organism. Probiotics are living microorganisms which, in specific conditions, confer a health benefit to the host. Among others, probiotics have immunomodulatory properties that usually act directly by (a) increasing the activity of macrophages or natural killer cells, (b) modulating the secretion of immunoglobulins or cytokines, or indirectly by (c) enhancing the gut epithelial barrier, (d) altering the mucus secretion, and (e) competitive exclusion of other (pathogenic) bacteria. This review focuses on specific bacteria strains with indirect immunomodulatory properties. Particularly, we describe here the mechanisms through which specific probiotics enhance the gut epithelial barrier and modulate mucus production. Moreover, we describe the antimicrobial properties of specific bacteria strains. Recent data suggest that multiple pathologies are associated with an unbalanced gut microflora (dysbiosis). Although the cause-effect relationship between pathology and gut microflora is not yet well established, consumption of specific probiotics may represent a powerful tool to re-establish gut homeostasis and promote gut health.

Interspecific competition alters natural selection on shade avoidance phenotypes in Impatiens capensis.

Science.gov (United States)

McGoey, Brechann V; Stinchcombe, John R

2009-08-01

Shade avoidance syndrome is a known adaptive response for Impatiens capensis growing in dense intraspecific competition. However, I. capensis also grow with dominant interspecific competitors in marshes. Here, we compare the I. capensis shade-avoidance phenotypes produced in the absence and presence of heterospecific competitors, as well as selection on those traits. Two treatments were established in a marsh; in one treatment all heterospecifics were removed, while in the other, all competitors remained. We compared morphological traits, light parameters, seed output and, using phenotypic selection analysis, examined directional and nonlinear selection operating in the different competitive treatments. Average phenotypes, light parameters and seed production all varied depending on competitive treatment. Phenotypic selection analyses revealed different directional, disruptive, stabilizing and correlational selection. The disparities seen in both phenotypes and selection between the treatments related to the important differences in elongation timing depending on the presence of heterospecifics, although environmental covariances between traits and fitness could also contribute. Phenotypes produced by I. capensis depend on their competitive environment, and differing selection on shade-avoidance traits between competitive environments could indirectly select for increased plasticity given gene flow between populations in different competitive contexts.

Judo strategy. The competitive dynamics of Internet time.

Science.gov (United States)

Yoffie, D B; Cusumano, M A

1999-01-01

Competition on the Internet is creating fierce battles between industry giants and small-scale start-ups. Smart start-ups can avoid those conflicts by moving quickly to uncontested ground and, when that's no longer possible, turning dominant players' strengths against them. The authors call this competitive approach judo strategy. They use the Netscape-Microsoft battles to illustrate the three main principles of judo strategy: rapid movement, flexibility, and leverage. In the early part of the browser wars, for instance, Netscape applied the principle of rapid movement by being the first company to offer a free stand-alone browser. This allowed Netscape to build market share fast and to set the market standard. Flexibility became a critical factor later in the browser wars. In December 1995, when Microsoft announced that it would "embrace and extend" competitors' Internet successes, Netscape failed to give way in the face of superior strength. Instead it squared off against Microsoft and even turned down numerous opportunities to craft deep partnerships with other companies. The result was that Netscape lost deal after deal when competing with Microsoft for common distribution channels. Netscape applied the principle of leverage by using Microsoft's strengths against it. Taking advantage of Microsoft's determination to convert the world to Windows or Windows NT, Netscape made its software compatible with existing UNIX systems. While it is true that these principles can't replace basic execution, say the authors, without speed, flexibility, and leverage, very few companies can compete successfully on Internet time.

EC Competition law and environmental protection

Energy Technology Data Exchange (ETDEWEB)

Rantala, M.

1996-12-31

Due to the increasing attention paid on environmental protection, by the European Community, the Member States and the consumers, undertakings are forced to adjust their policies to meet the new demands posed by public authorities and the market. This has an inevitable impact on competition. No matter how acceptable the goals were, the means are to be assessed also from the competition law point of view. The objective of this study is to analyze the situations where conflicts may take place, the main sources of research being the principles of law relating to the Treaty ,the judgements of the European Court of Justice, the Commission Decisions and other official documents of the Community as well as legal literature. This study classifies the Community and Member State instruments which are used for environmental protection into four categories. These are legislative, market-based, horizontal and financial supporting instruments. Undertakings` environmental practices, which are capable of affecting competition, are examined under Articles 85 and 86 EC, some attention being paid also to Article 90 EC. The touching points of competition policy and environmental protection in such cases are scrutinized under three headings. These are the two, in this case, most relevant public instruments, ie. legislative and market-based measures, and the voluntary actions of undertakings. (42 refs.)

The measure and significance of Bateman's principles.

Bateman's principles explain sex roles and sexual dimorphism through sex-specific variance in mating success, reproductive success and their relationships within sexes (Bateman gradients). Empirical tests of these principles, however, have come under intense scrutiny. Here, we experimentally show that in replicate groups of red junglefowl, Gallus gallus, mating and reproductive successes were more variable in males than in females, resulting in a steeper male Bateman gradient, consistent with Bateman's principles. However, we use novel quantitative techniques to reveal that current methods typically overestimate Bateman's principles because they (i) infer mating success indirectly from offspring parentage, and thus miss matings that fail to result in fertilization, and (ii) measure Bateman gradients through the univariate regression of reproductive over mating success, without considering the substantial influence of other components of male reproductive success, namely female fecundity and paternity share. We also find a significant female Bateman gradient but show that this likely emerges as spurious consequences of male preference for fecund females, emphasizing the need for experimental approaches to establish the causal relationship between reproductive and mating success. While providing qualitative support for Bateman's principles, our study demonstrates how current approaches can generate a misleading view of sex differences and roles.

Model for radiation damage in cells by direct effect and by indirect effect: a radiation chemistry approach

1978-01-01

A model is presented to describe the contributions of direct and indirect effects to the radiation damage of cells. The model is derived using principles of radiation chemistry and of pulse radiolysis in particular. From data available in the literature, parameters for cellular composition and values of rate constants for indirect action have been used in preliminary applications of the model. The results obtained in calculations of the protective effect of .OH and .H scavengers are consistent with experimental data. Possible modifications and improvements to the model are suggested, along with proposed future applications of the model in radiobiological studies

Full Text Available In marketing, the meaning of value is rapidly shifting from service and relationships to experiences. It is believed that the traditional value proposition is no longer effective to compete in the market and to gain customer loyalty. By adapting the brand experience model, this study tries to validate the model in the banking industry, which is currently facing intense competition to retain customers. The brand experience construct is tested for its direct and indirect relationship toward loyalty. It is postulated that satisfaction and brand authenticity might be instrumental in mediating brand experience to loyalty. Research was conducted via in-depth interview and quantitative survey, targeting bank customers in Jakarta. The result confirmed that brand experience has direct and indirect contribution to loyalty in significant and positive manner. The research contributes in validating previous studies with a rare emphasis in banking sector. The result implies that brand experience is an important value to lead to customer loyalty in this area and subject to growing research on experience marketing.

Differential scanning calorimetry (DSC) has been used to measure enthalpies of synthesis reactions of the 1-alkyl-3-methylimidazolium bromide [C(n)mim][Br] ionic liquids from 1-methylimidazole and n-alkyl bromides (with n = 4, 5, 6, 7, and 8). The optimal experimental conditions have been elaborated. Enthalpies of formation of these ionic liquids in the liquid state have been determined using the DSC results according to the Hess Law. The ideal-gas enthalpies of formation of [C(n)mim][Br] were calculated using the methods of quantum chemistry. They were used together with the DSC results to derive indirectly the enthalpies of vaporization of the ionic liquids under study. In order to validate the indirect determination, the experimental vaporization enthalpy of [C(4)mim][Br] was measured by using a quartz crystal microbalance (QCM). The combination of reaction enthalpy measurements by DSC with modern high-level first-principles calculations opens valuable indirect thermochemical options to obtain values of vaporization enthalpies of ionic liquids.

On the duration and intensity of cumulative advantage competitions

Jiang, Bo; Towsley, Don; Sun, Liyuan; Figueiredo, Daniel R; Ribeiro, Bruno

2015-01-01

Network growth can be framed as a competition for edges among nodes in the network. As with various other social and physical systems, skill (fitness) and luck (random chance) act as fundamental forces driving competition dynamics. In the context of networks, cumulative advantage (CA)—the rich-get-richer effect—is seen as a driving principle governing the edge accumulation process. However, competitions coupled with CA exhibit non-trivial behavior and little is formally known about duration and intensity of CA competitions. By isolating two nodes in an ideal CA competition, we provide a mathematical understanding of how CA exacerbates the role of luck in detriment of skill. We show, for instance, that when nodes start with few edges, an early stroke of luck can place the less skilled in the lead for an extremely long period of time, a phenomenon we call ‘struggle of the fittest’. We prove that duration of a simple skill and luck competition model exhibit power-law tails when CA is present, regardless of skill difference, which is in sharp contrast to the exponential tails when fitness is distinct but CA is absent. We also prove that competition intensity is always upper bounded by an exponential tail, irrespective of CA and skills. Thus, CA competitions can be extremely long (infinite mean, depending on fitness ratio) but almost never very intense. The theoretical results are corroborated by extensive numerical simulations. Our findings have important implications to competitions not only among nodes in networks but also in contexts that leverage socio-physical models embodying CA competitions. (paper)

Agrochemicals indirectly increase survival of E. coli O157:H7 and indicator bacteria by reducing ecosystem services.

Science.gov (United States)

Staley, Zachery R; Rohr, Jason R; Senkbeil, Jacob K; Harwood, Valerie J

Storm water and agricultural runoff frequently contain agrochemicals, fecal indicator bacteria (FIB), and zoonotic pathogens. Entry of such contaminants into aquatic ecosystems may affect ecology and human health. This study tested the hypothesis that the herbicide atrazine and the fungicide chlorothalonil indirectly affect the survival of FIB (Escherichia coli and Enterococcus faecalis) and a pathogen (E. coli O157:H7) by altering densities of protozoan predators or by altering competition from autochthonous bacteria. Streptomycin-resistant E. coli, En. faecalis, and E. coli O157:H7 were added to microcosms composed of Florida river water containing natural protozoan and bacterial populations. FIB, pathogen, and protozoan densities were monitored over six days. Known metabolic inhibitors, cycloheximide and streptomycin, were used to inhibit autochthonous protozoa or bacteria, respectively. The inhibitors made it possible to isolate the effects of predation or competition on survival of allochthonous bacteria, and each treatment increased the survival of FIB and pathogens. Chlorothalonil's effect was similar to that of cycloheximide, significantly reducing protozoan densities and elevating densities of FIB and pathogens relative to the control. Atrazine treatment did not affect protozoan densities, but, through an effect on competition, resulted in significantly greater densities of En. faecalis and E. coli O157:H7. Hence, by reducing predaceous protozoa and bacterial competitors that facilitate purifying water bodies of FIBs and human pathogens, chlorothalonil and atrazine indirectly diminished an ecosystem service of fresh water.

Cruel intentions on television and in real life: can viewing indirect aggression increase viewers' subsequent indirect aggression?

Science.gov (United States)

Coyne, Sarah M; Archer, John; Eslea, Mike

2004-07-01

Numerous studies have shown that viewing violence in the media can influence an individual's subsequent aggression, but none have examined the effect of viewing indirect aggression. This study examines the immediate effect of viewing indirect and direct aggression on subsequent indirect aggression among 199 children ages 11 to 14 years. They were shown an indirect, direct, or no-aggression video and their subsequent indirect aggression was measured by negative evaluation of a confederate and responses to a vignette. Participants viewing indirect or direct aggression gave a more negative evaluation of and less money to a confederate than participants viewing no-aggression. Participants viewing indirect aggression gave less money to the confederate than those viewing direct aggression. Participants viewing indirect aggression gave more indirectly aggressive responses to an ambiguous situation and participants viewing direct aggression gave more directly aggressive responses. This study provides the first evidence that viewing indirect aggression in the media can have an immediate impact on subsequent aggression.

Full Text Available Para entender en toda su complejidad tanto las potencialidades como las limitaciones de la competición deportiva para educar y transmitir valores consideramos esencial dirigir nuestra atención a la reflexión ética del deporte, y más concretamente a las dos líneas de pensamiento divergente sobre el valor ético de la competición deportiva. Para algunos autores en la naturaleza competitiva del deporte encontramos una esencia profundamente ética y transmisora de valores, mientras que para otros en dicha esencia competitiva radica el mayor problema ético del fenómeno deportivo. Más que tomar partido por alguna de ellas, nuestra intención es tratar de exponerlas y entenderlas en toda su complejidad ya que ambas argumentaciones están plagadas de matices interesantísimos. Finalizaremos el artículo presentando aquellos principios esenciales que deben guiar las competiciones deportivas que pretendan educar y transmitir valores a sus participantes, resguardando unos principios éticos esenciales.-----------------------------------------------------------------To understand the full complexity of both the potential and the limitations of competitive sports to educate and foster values we consider essential to turn our attention to ethical reflection in sport, and more specifically to the two lines of divergent thinking about the ethical value of sport competition. For some authors in the competitive nature of sport we find a deep ethical essence and transmitter of values, while for others in this competitive essence lies the greatest ethical problem of sports. Rather than siding with any of them, our intention is to try to show them and understand their complexity as both arguments have very interesting nuances. We end the paper presenting those essential principles that should guide sports competitions that seek to educate and teach values to their participants, protecting essential ethical principles

Competition and Consumer Behavior in the Context of the Digital Economy

2017-05-01

Full Text Available The current paper aims to investigate the relation between competition and online purchasing decision-making, integrating consumer protection awareness and the corresponding consumer behavior as mediators. The focus is on both subjective and objective measures related to the level of consumer awareness and action in a fast-growing competition, potentiated by the digital economy. In order to investigate the relations between the aforementioned concepts, a questionnaire-based survey was conducted, using a sample of 257 students from three top Romanian universities. Based upon the theoretical directions presented in the literature review, a conceptual model was elaborated and tested by employing a partial least squares structural equation modeling technique. As the examination of the structural model indicated, online purchasing decision-making is indirectly influenced by the high competition in the digital economy, by means of consumer protection awareness and consumer protection behavior. At this level, the analyzed factors, namely the competition in the digital economy, the consumer protection awareness and the consumer behavior with respect to the consumer protection policies, explain over 16% in the variance of the online purchasing decision-making.

A mini-max principle for drift waves and mesoscale fluctuations

International Nuclear Information System (INIS)

Itoh, S-I; Itoh, K

2011-01-01

A mini-max principle for the system of the drift waves and mesoscale fluctuations (e.g. zonal flows, etc) is studied. For the system of model equations a Lyapunov function is constructed, which takes the minimum when the stationary state is realized. The dynamical evolution describes the access to the state that is realized. The competition between different mesoscale fluctuations is explained. The origins of irreversibility that cause an approach to the stationary state are discussed. A selection rule among fluctuations is derived, and conditions, under which different kinds of mesocale fluctuations coexist, are investigated. An analogy of this minimum principle to the principle of 'minimum Helmholtz free energy' in thermal equilibrium is shown.

Is Nocturnal Foraging in a Tropical Bee an Escape From Interference Competition?

Smith, Adam R; Kitchen, Shannon M; Toney, Ryan M; Ziegler, Christian

2017-01-01

Temporal niche partitioning may result from interference competition if animals shift their activity patterns to avoid aggressive competitors. If doing so also shifts food sources, it is difficult to distinguish the effects of interference and consumptive competition in selecting for temporal niche shift. Bees compete for pollen and nectar from flowers through both interference and consumptive competition, and some species of bees have evolved nocturnality. Here, we use tropical forest canopy towers to observe bees (the night-flying sweat bees Megalopta genalis and M. centralis [Halictidae], honey bees, and stingless bees [Apidae]) visiting flowers of the balsa tree (Ochroma pyramalidae, Malvaceae). Because Ochroma flowers are open in the late afternoon through the night we can test the relative influence of each competition type on temporal nice. Niche shift due to consumptive competition predicts that Megalopta forage when resources are available: from afternoon into the night. Niche shift due to interference competition predicts that Megalopta forage only in the absence of diurnal bees. We found no overlap between diurnal bees and Megalopta in the evening, and only one instance of overlap in the morning, despite the abundance of pollen and nectar in the late afternoon and evening. This supports the hypothesis that Megalopta are avoiding interference competition, but not the hypothesis that they are limited by consumptive competition. We propose that the release from interference competition enables Megalopta to provision cells quickly, and spend most of their time investing in nest defense. Thus, increases in foraging efficiency directly resulting from temporal shifts to escape interference competition may indirectly lead to reduced predation and parasitism. © The Authors 2017.

Development of an indirect counterbalanced pendulum optical-lever thrust balance for micro- to millinewton thrust measurement

International Nuclear Information System (INIS)

Grubišić, A N; Gabriel, S B

2010-01-01

This paper describes the design and testing of an indirect hanging pendulum thrust balance using a laser-optical-lever principle to provide micro- to millinewton thrust measurement for the development of electric propulsion systems. The design philosophy allows the selection of the total thrust range in order to maximize resolution through a counterbalanced pendulum principle, as well as passive magnetic damping in order to allow relatively rapid transient thrust measurement. The balance was designed for the purpose of hollow cathode microthruster characterization, but could be applied to other electric propulsion devices in the thrust range of micro- to millinewtons. An initial thrust characterization of the T5 hollow cathode is presented

Competition as a source of constraint on life history evolution in natural populations.

Science.gov (United States)

Wilson, A J

2014-01-01

Competition among individuals is central to our understanding of ecology and population dynamics. However, it could also have major implications for the evolution of resource-dependent life history traits (for example, growth, fecundity) that are important determinants of fitness in natural populations. This is because when competition occurs, the phenotype of each individual will be causally influenced by the phenotypes, and so the genotypes, of competitors. Theory tells us that indirect genetic effects arising from competitive interactions will give rise to the phenomenon of 'evolutionary environmental deterioration', and act as a source of evolutionary constraint on resource-dependent traits under natural selection. However, just how important this constraint is remains an unanswered question. This article seeks to stimulate empirical research in this area, first highlighting some patterns emerging from life history studies that are consistent with a competition-based model of evolutionary constraint, before describing several quantitative modelling strategies that could be usefully applied. A recurrent theme is that rigorous quantification of a competition's impact on life history evolution will require an understanding of the causal pathways and behavioural processes by which genetic (co)variance structures arise. Knowledge of the G-matrix among life history traits is not, in and of itself, sufficient to identify the constraints caused by competition.

Municipal Competition for Inhabitants under Population Decrease. Zusammenfassung: Kommunale Konkurrenz um Einwohner bei Bevölkerungsrückgang

Directory of Open Access Journals (Sweden)

Peter Friedrich

2014-12-01

Full Text Available The shrinking population during the break-down, adaptation and recovery phase in Estonian social and political development enforces municipal competition among the municipalities. Competition for inhabitants is embedded in regional competition showing horizontal and vertical competition relations. Inhabitants’ competition prevails indirectly through municipal business promotion competition and directly through competition for inhabitants. The competition shows three phases. A phase concerns zoning and long-term planning; a second one refers to negotiations with settlement firms and short-term actions to attract inhabitants followed by a phase of revisions of zoning and measures. The oligopolistic industrial zoning model of business promotion policy points to the consequences of horizontal municipal competition also on population. Vertical influences on business promotion policy demonstrate a game-theoretic example of intergovernmental intervention from higher government on zoning. The negotiation phase in business promotion policy is modelled by a bilateral monopoly model between a municipality and a settlement firm. Horizontal regional competition highlights the implications on inhabitants’ competition. An oligopoly model of direct inhabitant competition concerns the zoning in particular for housing. Furthermore, a model of public enterprise service and fee formation and of horizontal public firm competition shows inhabitants’ competition in the second phase. Forms of inhabitant competition concerning suburbanisation and using public debt, revenues such as taxes, fees and expenditures are mentioned. Finally, follows a discussion of possible instruments to regulate inhabitant competition.

The Impact of Groupement des Cartes Bancaires on Competition Law Enforcement

Directory of Open Access Journals (Sweden)

Piero Fattori

2015-10-01

Full Text Available The Groupement des Cartes bancaires represents a key judgment for competition enforcement, as it provides helpful clarification on the notion of “restriction by object” and on the judicial standard of review of Commission decisions. As of the first aspect, the ruling limited the restrictions by object to those which by their very nature and on the basis of the experience reveal a sufficient degree of harm to competition. On the standard required to the Court in reviewing competition decisions, the ECJ underlines the necessity of carrying out a full review, specifying that the presence of economic issues should not dispense the Court with an in-depth review of the law and the facts. The principles expressed in the judgment could have a great impact also at national level, where it could provide useful guidance both to Italian competition authority and to the Administrative Courts.

Underground friends or enemies: model plants help to unravel direct and indirect effects of arbuscular mycorrhizal fungi on plant competition.

Facelli, Evelina; Smith, Sally E; Facelli, José M; Christophersen, Helle M; Andrew Smith, F

2010-03-01

*We studied the effects of two arbuscular mycorrhizal (AM) fungi, singly or together, on the outcome of competition between a host (tomato cultivar, wild-type (WT)) and a surrogate nonhost (rmc, a mycorrhiza-defective mutant of WT) as influenced by the contributions of the direct and AM phosphorus (P) uptake pathways to plant P. *We grew plants singly or in pairs of the same or different genotypes (inoculated or not) in pots containing a small compartment with (32)P-labelled soil accessible to AM fungal hyphae and determined expression of orthophosphate (P(i)) transporter genes involved in both AM and direct P uptake. *Gigaspora margarita increased WT competitive effects on rmc. WT and rmc inoculated with Glomus intraradices both showed growth depressions, which were mitigated when G. margarita was present. Orthophosphate transporter gene expression and (32)P transfer showed that the AM pathway operated in single inoculated WT, but not in rmc. *Effects of AM fungi on plant competition depended on the relative contributions of AM and direct pathways of P uptake. Glomus intraradices reduced the efficiency of direct uptake in both WT and rmc. The two-fungus combination showed that interactions between fungi are important in determining outcomes of plant competition.

How malleable is categorization by race? Evidence for competitive category use in social categorization.

Klauer, Karl Christoph; Hölzenbein, Fabian; Calanchini, Jimmy; Sherman, Jeffrey W

2014-07-01

We contrast 3 theoretical viewpoints concerning the factors affecting social categorization by race: (a) the classical theory of social categorization highlighting the role of a priori accessibility and situational factors, (b) the classical theory augmented by a principle of competitive category use, and (c) competition between race (but not gender) and coalition with race (but not gender) encoded only as a proxy to coalition. Study 1 documents a confound that renders important portions of previous research difficult to interpret. In Studies 2 and 3, race categorization was stronger than categorization by more weakly accessible categories when situational support in terms of topic relevance was comparable across categories. A situational focus on race further increased race categorization. Race categorization was reduced in the presence of strongly cued cross-cutting coalitions. Race categorization also was depressed when situational factors promoted comparative processing of cross-cutting categories while cues to potential coalitional divisions were held constant (Study 4). Accessibility, topic relevance, and cuing cross-cutting coalitions had the same effects on gender categorization as found for race categorization (Study 5). Taken together, the results suggest that classical theories of social categorization have to be augmented by a principle of competitive category use that is not limited to a competition between race and coalition.

Competitive outcome of Daphnia-Simocephalus experimental microcosms: salinity versus priority effects.

Directory of Open Access Journals (Sweden)

Cláudia Loureiro

Full Text Available Competition is a major driving force in freshwaters, especially given the cyclic nature and dynamics of pelagic food webs. Competition is especially important in the initial species assortment during colonization and re-colonization events, which depends strongly on the environmental context. Subtle changes, such as saline intrusion, may disrupt competitive relationships and, thus, influence community composition. Bearing this in mind, our objective was to assess whether low salinity levels (using NaCl as a proxy alter the competitive outcome (measured as the rate of population biomass increase of Daphnia-Simocephalus experimental microcosms, taking into account interactions with priority effects (sequential species arrival order. With this approach, we aimed to experimentally demonstrate a putative mechanism of differential species sorting in brackish environments or in freshwaters facing secondary salinization. Experiments considered three salinity levels, regarding NaCl added (0.00, 0.75 and 1.50 g L(-1, crossed with three competition scenarios (no priority, priority of Daphnia over Simocephalus, and vice-versa. At lower NaCl concentrations (0.00 and 0.75 g L(-1, Daphnia was a significantly superior competitor, irrespective of the species inoculation order, suggesting negligible priority effects. However, the strong decrease in Daphnia population growth at 1.50 g L(-1 alleviated the competitive pressure on Simocephalus, causing an inversion of the competitive outcome in favour of Simocephalus. The intensity of this inversion depended on the competition scenario. This salinity-mediated disruption of the competitive outcome demonstrates that subtle environmental changes produce indirect effects in key ecological mechanisms, thus altering community composition, which may lead to serious implications in terms of ecosystem functioning (e.g. lake regime shifts due to reduced grazing and biodiversity.

Koehn, Stefan

2013-01-01

Confidence and anxiety are important variables that underlie the experience of flow in sport. Specifically, research has indicated that confidence displays a positive relationship and anxiety a negative relationship with flow. The aim of this study was to assess potential direct and indirect effects of confidence and anxiety dimensions on flow state in tennis competition. A sample of 59 junior tennis players completed measures of Competitive State Anxiety Inventory-2d and Flow State Scale-2. Following predictive analysis, results showed significant positive correlations between confidence (intensity and direction) and anxiety symptoms (only directional perceptions) with flow state. Standard multiple regression analysis indicated confidence as the only significant predictor of flow. The results confirmed a protective function of confidence against debilitating anxiety interpretations, but there were no significant interaction effects between confidence and anxiety on flow state.

The Ground Rules for Effective OBAs: Principles for Addressing Carbon-Pricing Competitiveness Concerns through the Use of Output-Based Allocations

Directory of Open Access Journals (Sweden)

Sarah Dobson

2017-06-01

Full Text Available The federal government’s decision to impose a minimum national price on carbon emissions has the potential to make certain businesses in the country less competitive. Specifically, there are emissions-intensive and trade-exposed industries across Canada that compete against producers from other jurisdictions where governments do not put a price on carbon. For these industries, the obligation to pay a carbon price creates a competitive disadvantage. Specifically, these businesses will face higher costs and may encounter a loss of market share to international competitors from jurisdictions that lack the same emission-control measures. That not only hurts Canadian businesses, it could also negate any emissions reductions that carbon pricing in Canada achieves on a global scale. The federal government has opted to protect such emissions-intensive, tradeexposed businesses using subsidies called output-based allocations (OBAs. This is the same system that Alberta is introducing through its forthcoming Carbon Competiveness Regulation. It also shares certain similarities with cap-and-trade programs, such as those in Ontario and Quebec, which provide free allocations of emissions permits to certain firms. OBAs are a desirable complementary policy to a carbon price as they maintain the incentive for producers to invest in production methods and facilities that are less emissions intensive. So while producers are still, nevertheless, subsidized to offset the tax burden of the carbon price, they will, under an OBA system, see greater benefits the more they work to reduce their emissions intensity. Still, to function most effectively and most efficiently, an OBA policy should follow certain key principles. The most critical principle in the design of an OBA policy is ensuring that OBAs are allocated to facilities independent of their individual emission levels, and allocated equally (on a per unit basis to facilities producing the same product. One of the

Competition and dental services.

Science.gov (United States)

Grytten, J; Sørensen, R

2000-07-01

Dental services for adults are different from all other Norwegian health services in that they are provided by private producers (dentists) who have full freedom to establish a practice. They have had this freedom since the end of World War II. A further liberalization of the market for dental services occurred in November 1995, when the so-called normal tariff was repealed. The system changed from a fixed fee system to a deregulated fee system. In principle, the market for dental services for adults operates as a free competitive market, in which dentists must compete for a market share. The aim of this study was to study the short-term effects of competition. A comprehensive set of data on fees, practice characteristics, treatment profiles and factors that dentists take into account when determining fees was analysed. The main finding was that competition has a weak effect. No support was found for the theory that the level of fees is the result of monopolistic competition or monopoly. The results also provided some evidence against the inducement hypothesis. At this stage, it is interesting to notice that dentists do not seem to exploit the power they have to control the market. One explanation, which is consistent with the more recent literature, is that physicians' behaviour to a large extent is influenced by professional norms and caring concerns about their patients. Financial incentives are important, but these incentives are constrained by norms other than self-interest. The interpretation of the results should also take into account that the deregulation has operated for a short time and that dentists and patients may not yet have adjusted to changes in the characteristics of the market.

Indirect three-dimensional printing of synthetic polymer scaffold based on thermal molding process

International Nuclear Information System (INIS)

Park, Jeong Hun; Jung, Jin Woo; Cho, Dong-Woo; Kang, Hyun-Wook

2014-01-01

One of the major issues in tissue engineering has been the development of three-dimensional (3D) scaffolds, which serve as a structural template for cell growth and extracellular matrix formation. In scaffold-based tissue engineering, 3D printing (3DP) technology has been successfully applied for the fabrication of complex 3D scaffolds by using both direct and indirect techniques. In principle, direct 3DP techniques rely on the straightforward utilization of the final scaffold materials during the actual scaffold fabrication process. In contrast, indirect 3DP techniques use a negative mold based on a scaffold design, to which the desired biomaterial is cast and then sacrificed to obtain the final scaffold. Such indirect 3DP techniques generally impose a solvent-based process for scaffold fabrication, resulting in a considerable increase in the fabrication time and poor mechanical properties. In addition, the internal architecture of the resulting scaffold is affected by the properties of the biomaterial solution. In this study, we propose an advanced indirect 3DP technique using projection-based micro-stereolithography and an injection molding system (IMS) in order to address these challenges. The scaffold was fabricated by a thermal molding process using IMS to overcome the limitation of the solvent-based molding process in indirect 3DP techniques. The results indicate that the thermal molding process using an IMS has achieved a substantial reduction in scaffold fabrication time and has also provided the scaffold with higher mechanical modulus and strength. In addition, cell adhesion and proliferation studies have indicated no significant difference in cell activity between the scaffolds prepared by solvent-based and thermal molding processes. (paper)

Full Text Available In a financial economic scenario in which the corporate survival of small and medium enterprises (SMEs is more conditioned than ever by competitive performance, this paper aims to show that the strategic incorporation of socially responsible actions, more concerned and engaged with stakeholders, contributes to improve the competitiveness of these organizations. Thus, the existence of a direct or mediated relationship between the development of Corporate Social Responsibility (CSR practices and competitive performance has been analyzed from a multi-stakeholder perspective. To accomplish this task, data were collected from a sample of 481 Spanish SMEs and the technique of partial least squares (PLS was used. Outcomes show that the development of CSR practices contributes to increase the competitive performance both directly and indirectly, through the ability of these organizations to manage their stakeholders. This study, therefore, supports the social impact hypothesis and offers evidence about some intangibles such as the relational capacity mediate the causal effect between CSR and competitive performance.

Competition Law and the Nuclear Sector: An EU Outlook

International Nuclear Information System (INIS)

Sousa Ferro, M.

2010-01-01

Competition law essentially aims at preventing harmful distortions of competition in the market which may be caused by agreements between companies, by the abusive behaviour of dominant companies, by structural changes in the market due to mergers or by state aid.1 However, often such practices and measures are actually necessary to render certain services viable, to obtain new or better products, to pursue other policies for the greater benefit of the collective, etc. Occasionally, this raises interesting issues in the nuclear sector. This paper aims to provide European competition law practitioners with a summary of the leading legal issues and precedents in this domain, alerting them to relevant specifics. It also aims to introduce nuclear lawyers to the reality and potential of antitrust enforcement in this sector. For the purposes of this paper, the 'nuclear sector' shall be broadly defined so as to include any activity which, given its link to nuclear energy or to ionizing radiation, is (at least partially) subject to special regulation under nuclear law. While many nuclear-related activities will not, in principle, require a special analysis beyond the usual parameters of competition law enforcement, others present distinct challenges to practitioners. Some of these challenges are specific to the European legal order and justify the restriction of the scope of this analysis to the European Union. That being said, the extensive harmonization of the national competition law of member states, as well as the fact that national competition authorities are required to enforce EU competition law, makes it advisable to look simultaneously at European-wide and national antitrust enforcement. The relationship between EU competition law and the nuclear sector remains somewhat shrouded in mystery - perhaps excessively so. The issue has been tackled to some extent in general works on competition law and energy law. As one would expect, research developed in the framework

Recently, searching large-bulk band gap topological insulator (TI) is under intensive study. Through k?P theory and first-principles calculations analysis on antimonene, we find that ?-phase antimonene can be tuned to a 2D TI under an in-plane anisotropic strain and the magnitude of direct bulk band gap (SOC gap) depends on the strength of spin-orbit coupling (SOC) which is strain-dependent. As the band inversion of this TI accompanies with an indirect band gap, the TI bulk band gap is the in...

CURRENT TRENDS IN TAX HARMONIZATION AND COMPETITION WITHIN THE EUROPEAN UNION

Directory of Open Access Journals (Sweden)

Gherman Adela-Teodora

2010-12-01

Full Text Available This article treats on the fiscal harmonization process within the European Union being indispensable for assuring loyalty in the competition on its single market, given the fact that different system of taxation had direct and powerful impact on the prices level and on chosing the location for production and distribution activities. Both direct and indirect taxation distort the four fundamental freedoms of the single market. Most of the European Unions regulations regarding fiscal harmonization resemble to the Directive regarding especially the indirect taxes: VAT, Excises. The fiscal reforms from the member states have to be conceived in such a manner that they take into account the necessity of fiscal harmonization on EU level, creating a reasonable compromise between each country's sovereignty and the desideratum of removing fiscal barriers from the normal functioning of the single market.

Direct and Indirect Influence of Non-Native Neighbours on Pollination and Fruit Production of a Native Plant.

Ana Montero-Castaño

Full Text Available Entomophilous non-native plants can directly affect the pollination and reproductive success of native plant species and also indirectly, by altering the composition and abundance of floral resources in the invaded community. Separating direct from indirect effects is critical for understanding the mechanisms underlying the impacts of non-native species on recipient communities.Our aims are: (a to explore both the direct effect of the non-native Hedysarum coronarium and its indirect effect, mediated by the alteration of floral diversity, on the pollinator visitation rate and fructification of the native Leopoldia comosa and (b to distinguish whether the effects of the non-native species were due to its floral display or to its vegetative interactions.We conducted field observations within a flower removal experimental setup (i.e. non-native species present, absent and with its inflorescences removed at the neighbourhood scale.Our study illustrates the complexity of mechanisms involved in the impacts of non-native species on native species. Overall, Hedysarum increased pollinator visitation rates to Leopoldia target plants as a result of direct and indirect effects acting in the same direction. Due to its floral display, Hedysarum exerted a direct magnet effect attracting visits to native target plants, especially those made by the honeybee. Indirectly, Hedysarum also increased the visitation rate of native target plants. Due to the competition for resources mediated by its vegetative parts, it decreased floral diversity in the neighbourhoods, which was negatively related to the visitation rate to native target plants. Hedysarum overall also increased the fructification of Leopoldia target plants, even though such an increase was the result of other indirect effects compensating for the observed negative indirect effect mediated by the decrease of floral diversity.

Impact of Interference Competition on Exploration and Food Exploitation in the Ant Lasius niger

Directory of Open Access Journals (Sweden)

Vincent Fourcassié

2012-01-01

Full Text Available Competition acts as a major force in shaping spatially and/or temporally the foraging activity of ant colonies. Interference competition between colonies in particular is widespread in ants where it can prevent the physical access of competitors to a resource, either directly by fighting or indirectly, by segregating the colony foraging areas. Although the consequences of interference competition on ant distribution have been well studied in the literature, the behavioral mechanisms underlying interference competition have been less explored. Little is known on how ants modify their exploration patterns or the choice of a feeding place after experiencing aggressive encounters. In this paper, we show that, at the individual level, the aphid-tending ant Lasius niger reacts to the presence of an alien conspecific through direct aggressive behavior and local recruitment in the vicinity of fights. At the colony level, however, no defensive recruitment is triggered and the “risky” area where aggressive encounters occur is not specifically avoided during further exploration or food exploitation. We discuss how between-species differences in sensitivity to interference competition could be related to the spatial and temporal predictability of food resources at stake.

Full Text Available This paper studies the information and communication technology (ICT in a small hotel sector at a point in time when the transition towards a full market economy is coming to the end and competitiveness and ICT implementation is gaining on importance. Its main purpose is to study a business potential of this new competitive advantage resource and its productivity paradox. A competitive advantage factor model (CAF model has been proposed and the structural modelling (SEM has been performed on the case of a small transitional Slovenian hotel sector. The study contributes to knowledge on ICT competiveness and ICT productivity paradox in hotel sector. Further, its results hold practical implications for the strategy for hotels operating in small-sized hotel industries in transitional or ICT developing environments. In more concrete terms, research findings indicate that such hotel sectors need to speed the ICT implementation. ICT as such doesn’t directly increase the firm’s profitability, yet there is an indirect positive impact of factor ICT on a firm’s financial performance that emerges through other competitiveness factors, such as differentiation, quality or image, which helps firms to stay competitive on the tourism markets.

Principle of minimum distance in space of states as new principle in quantum physics

The mathematician Leonhard Euler (1707-1783) appears to have been a philosophical optimist having written: 'Since the fabric of universe is the most perfect and is the work of the most wise Creator, nothing whatsoever take place in this universe in which some relation of maximum or minimum does not appear. Wherefore, there is absolutely no doubt that every effect in universe can be explained as satisfactory from final causes themselves the aid of the method of Maxima and Minima, as can from the effective causes'. Having in mind this kind of optimism in the papers mentioned in this work we introduced and investigated the possibility to construct a predictive analytic theory of the elementary particle interaction based on the principle of minimum distance in the space of quantum states (PMD-SQS). So, choosing the partial transition amplitudes as the system variational variables and the distance in the space of the quantum states as a measure of the system effectiveness, we obtained the results presented in this paper. These results proved that the principle of minimum distance in space of quantum states (PMD-SQS) can be chosen as variational principle by which we can find the analytic expressions of the partial transition amplitudes. In this paper we present a description of hadron-hadron scattering via principle of minimum distance PMD-SQS when the distance in space of states is minimized with two directional constraints: dσ/dΩ(±1) = fixed. Then by using the available experimental (pion-nucleon and kaon-nucleon) phase shifts we obtained not only consistent experimental tests of the PMD-SQS optimality, but also strong experimental evidences for new principles in hadronic physics such as: Principle of nonextensivity conjugation via the Riesz-Thorin relation (1/2p + 1/2q = 1) and a new Principle of limited uncertainty in nonextensive quantum physics. The strong experimental evidence obtained here for the nonextensive statistical behavior of the [J, �

The majority of research on the link between video games and aggression has focused on the violent content in games. In contrast, recent experimental research suggests that it is video game competition, not violence, that has the greatest effect on aggression in the short-term. However, no researchers have examined the long-term relationship between video game competition and aggression. In addition, if competition in video games is a significant reason for the link between video game play and aggression, then other competitive activities, such as competitive gambling, also may predict aggression over time. In the current study, we directly assessed the socialization (competitive video game play and competitive gambling predicts aggression over time) versus selection hypotheses (aggression predicts competitive video game play and competitive gambling over time). Adolescents (N = 1,492, 50.8 % female) were surveyed annually from Grade 9 to Grade 12 about their video game play, gambling, and aggressive behaviors. Greater competitive video game play and competitive gambling predicted higher levels of aggression over time, after controlling for previous levels of aggression, supporting the socialization hypothesis. The selection hypothesis also was supported, as aggression predicted greater competitive video game play and competitive gambling over time, after controlling for previous competitive video game play and competitive gambling. Our findings, taken together with the fact that millions of adolescents play competitive video games every day and that competitive gambling may increase as adolescents transition into adulthood, highlight the need for a greater understanding of the relationship between competition and aggression.

Meeting the near-term demand for hydrogen using nuclear energy in competitive power markets

International Nuclear Information System (INIS)

Miller, A.I.; Duffey, R.B.

2004-01-01

Hydrogen is becoming the reference fuel for future transportation and the timetable for its adoption is shortening. However, to deploy its full potential, hydrogen production either directly or indirectly needs to satisfy three criteria: no associated emissions, including CO 2 ; wide availability; and affordability. This creates a window of great opportunity within the next 15 years for nuclear energy to provide the backbone of hydrogen-based energy systems. But nuclear must establish its hydrogen generating role long before the widespread deployment of Gen IV high-temperature reactors, with their possibility of producing hydrogen directly by heat rather than electricity. For Gen IV the major factors will be efficiency and economic cost, particularly if centralized storage is needed and/or credits for avoided emissions and/or oxygen sales. In the interim, despite its apparently lower overall efficiency, water electrolysis is the only available technology today able to meet the first and second criteria. The third criterion includes costs of electrolysis and electricity. The primary requirements for affordable electrolysis are low capital cost and high utilisation. Consequently, the electricity supply must enable high utilisation as well as being itself low-cost and emissions-free. Evolved Gen III+ nuclear technologies can produce electricity on large scales and at rates competitive with today's CO 2 -emitting, fossil-fuelled technologies. As an example of electrolytic hydrogen's potential, we show competitive deployment in a typical competitive power market. Among the attractions of this approach are reactors supplying a base-loaded market - though permitting occasional, opportunistic diversion of electricity during price spikes on the power grid - and easy delivery of hydrogen to widely distributed users. Gen IV systems with multiple product streams and higher efficiency (e.g., the SCWR) can also be envisaged which can use competitive energy markets to advantage

Total, direct, and indirect effects of paan on oral cancer.

2015-03-01

Paan (betel leaf and betel nut quid) used with or without tobacco has been positively associated with oral cancer. Oral submucous fibrosis (OSMF), a precancerous condition caused by paan, lies on the causal pathway between paan use and oral cancer. The purpose of this analysis was to estimate the effect of paan consumption on oral cancer risk when it is mediated by OSMF. We used mediation methods proposed by VanderWeele, which are based on causal inference principles, to characterize the total, direct, and indirect effects of paan, consumed with and without tobacco, on oral cancer mediated by OSMF. We reanalyzed case-control data collected from three hospitals in Karachi, Pakistan, between July 1996 and March 1998. For paan without tobacco, the total effect on oral cancer was OR 7.39, 95 % CI 1.01, 38.11, the natural indirect effect (due to OSMF among paan users) was OR 2.48, 95 % CI 0.99, 10.44, and the natural direct effect (due to paan with OSMF absent) was OR 3.32, 95 % CI 0.68, 10.07. For paan with tobacco, the total direct effect was OR 15.68, 95 % CI 3.00, 54.90, the natural indirect effect was OR 2.18, 95 % CI 0.82, 5.52, and the natural direct effect was OR 7.27, 95 % CI 2.15, 20.43. Paan, whether or not it contained tobacco, raised oral cancer risk irrespective of OSMF. Oral cancer risk was higher among those who used paan with tobacco.

Alterations to multisensory and unisensory integration by stimulus competition.

Pluta, Scott R; Rowland, Benjamin A; Stanford, Terrence R; Stein, Barry E

In environments containing sensory events at competing locations, selecting a target for orienting requires prioritization of stimulus values. Although the superior colliculus (SC) is causally linked to the stimulus selection process, the manner in which SC multisensory integration operates in a competitive stimulus environment is unknown. Here we examined how the activity of visual-auditory SC neurons is affected by placement of a competing target in the opposite hemifield, a stimulus configuration that would, in principle, promote interhemispheric competition for access to downstream motor circuitry. Competitive interactions between the targets were evident in how they altered unisensory and multisensory responses of individual neurons. Responses elicited by a cross-modal stimulus (multisensory responses) proved to be substantially more resistant to competitor-induced depression than were unisensory responses (evoked by the component modality-specific stimuli). Similarly, when a cross-modal stimulus served as the competitor, it exerted considerably more depression than did its individual component stimuli, in some cases producing more depression than predicted by their linear sum. These findings suggest that multisensory integration can help resolve competition among multiple targets by enhancing orientation to the location of cross-modal events while simultaneously suppressing orientation to events at alternate locations.

Indirect Self-Destructiveness and Emotional Intelligence.

Tsirigotis, Konstantinos

2016-06-01

While emotional intelligence may have a favourable influence on the life and psychological and social functioning of the individual, indirect self-destructiveness exerts a rather negative influence. The aim of this study has been to explore possible relations between indirect self-destructiveness and emotional intelligence. A population of 260 individuals (130 females and 130 males) aged 20-30 (mean age of 24.5) was studied by using the Polish version of the chronic self-destructiveness scale and INTE, i.e., the Polish version of the assessing emotions scale. Indirect self-destructiveness has significant correlations with all variables of INTE (overall score, factor I, factor II), and these correlations are negative. The intensity of indirect self-destructiveness differentiates significantly the height of the emotional intelligence and vice versa: the height of the emotional intelligence differentiates significantly the intensity of indirect self-destructiveness. Indirect self-destructiveness has negative correlations with emotional intelligence as well as its components: the ability to recognize emotions and the ability to utilize emotions. The height of emotional intelligence differentiates the intensity of indirect self-destructiveness, and vice versa: the intensity of indirect self-destructiveness differentiates the height of emotional intelligence. It seems advisable to use emotional intelligence in the prophylactic and therapeutic work with persons with various types of disorders, especially with the syndrome of indirect self-destructiveness.

Full Text Available This study examined instantaneous and cumulative effects of competitive interactions on impulsiveness in the inter-temporal choices in domestic chicks. Chicks were trained to peck colored beads to gain delayed food rewards (1 or 6 grains of millet delivered after a delay ranging between 0–4.5 s, and were tested in binary choices between a small-short delay option (SS and a large-long delay alternative (LL. To examine whether competitive foraging instantaneously changes impulsiveness, we intraindividually compared choices between two consecutive tests in different contexts, one with competitors and another without. We found that (1 the number of the choice of LL was not influenced by competition in the tests, but (2 the operant peck latency was shortened by competition, suggesting a socially enhanced incentive for food. To further examine the lasting changes, two groups of chicks were consecutively trained and tested daily for 2 weeks according to a behavioral titration procedure, one with competitors and another without. Inter-group comparisons of the choices revealed that (3 choice impulsiveness gradually decreased along development, while (4 the chicks trained in competition maintained a higher level of impulsiveness. These results suggest that competitive foraging causes impulsive choices not by direct/contextual modification. Causal link between the instantaneous enhancement of incentive and the gradual effects on impulsivity remains to be examined. Some (yet unspecified factors may be indirectly involved.

The paper defines and classifies essential issues that relate the need for electric power system coordination with the increasing development of competition. Principles are formulated and a coordination model and a market structure are proposed, emphasizing the need for economic dispatch in the wholesale market. A detailed comparison is made of the market and pooling implementations developed in Argentina and Chile, countries that have pioneered the creation of competitive markets in the electric energy sector. An evaluation of strengths and weaknesses of those two implementations is included

Bacterial stigmergy: an organising principle of multicellular collective behaviours of bacteria.

Science.gov (United States)

Gloag, Erin S; Turnbull, Lynne; Whitchurch, Cynthia B

2015-01-01

The self-organisation of collective behaviours often manifests as dramatic patterns of emergent large-scale order. This is true for relatively "simple" entities such as microbial communities and robot "swarms," through to more complex self-organised systems such as those displayed by social insects, migrating herds, and many human activities. The principle of stigmergy describes those self-organised phenomena that emerge as a consequence of indirect communication between individuals of the group through the generation of persistent cues in the environment. Interestingly, despite numerous examples of multicellular behaviours of bacteria, the principle of stigmergy has yet to become an accepted theoretical framework that describes how bacterial collectives self-organise. Here we review some examples of multicellular bacterial behaviours in the context of stigmergy with the aim of bringing this powerful and elegant self-organisation principle to the attention of the microbial research community.

Ntoumanis, N; Biddle, S

1998-06-01

The purpose of this study was to examine the relationships of achievement goal orientations and perceived motivational climate to perceptions of the intensity and direction of competitive state anxiety in a sample of university athletes representing various team sports. Although some studies have demonstrated that task orientation and mastery climate are associated with adaptive emotional patterns and ego orientation and performance climate are linked to less adaptive emotions, others have not verified these findings. In the present study, structural equation modeling was used to test these links. The results showed that perceptions of a performance climate were associated with ego orientation, whereas perceptions of a mastery climate were linked to task orientation. Furthermore, no significant links were found between task orientation and direction of competitive anxiety, while it was shown that the impact of ego orientation on the intensity and direction of cognitive and somatic anxiety was exerted through self-confidence. No significant direct links were found between motivational climates and competitive anxiety, thus implying that motivational climates may have an indirect impact on affective responses through the different goal orientations. The findings of the present study are discussed along with suggestions for examining situational and individual difference variables that may explain the relationships between intensity and direction of competitive anxiety and achievement goals and motivational climates.

In principle, district heating systems come in the application area of paragraph 19 sect. 4 no. 4 GWB (law against competitive restrictions). However, this regulation has to be interpreted with respect to the legislation of the Court of Justice of the European Union (Luxemburg) to 'essential facilities'. According to this, the claim for antitrust access can be affirmed only in exceptional circumstances. Within the application of this regulation, property rights, competition protection, investment competition, innovation competition as well as energy political evaluations of the energy law under special consideration of ecologic and climate political targets are considered. This has to occur within the testing of the reasonability with respect to paragraph 19 sect. 4 no. 2 GWB. The particularities of the district heating.

Grossberg established a remarkable convergence theorem for a class of competitive systems without knowing and using Lyapunov function for the systems. We present the parallel investigations for the discrete-time version of the Grossberg's model. Through developing an extended component-competing analysis for the coupled system, without knowing a Lyapunov function and applying the LaSalle's invariance principle, the global pattern formation or the so-called global consensus for the system can be achieved. A numerical simulation is performed to illustrate the present theory.

FISCAL COMPETITION AND DIRECT FOREIGN INVESTMENTS: ROMANIA VERSUS POLAND

Directory of Open Access Journals (Sweden)

2012-12-01

Full Text Available The European Economic Community treaty defines indirect taxation common rules taking into consideration their impact upon free merchandise’s circulation and upon international commercial exchanges. Once the Roma treaty has been signed (1957 the established scope was creating a common market. But, how is it possible to create a common market without any monetary and fiscal instruments? Thus, these instruments have had to be created in order to achieve such an objective. If from the monetary point of view introducing euro as a common currency was a big step ahead, from the fiscal point of view things haven’t evolved in such an easy manner. Fiscal objectives are achieved only if the national market is running normally and correctly. Indirect taxation is harmonized base upon article 113 from the European Union Treaty, while regarding direct taxation legal recommendations and regulations approval we can’t talk about harmonization but about fiscal competition. We are stating this because there are 27 states in the European Union and each one is sustaining its own direct taxation system. Furthermore, the taxation system (fiscal system is influencing member states economical performances through economies, investments and human capital formation by affecting the revenue’s distribution, research and development expenses level and type and by fiscal competition – an effect more and more profound. In this context we aim at analyzing the way fiscal competition had had a positive impact upon attracting foreign direct investments in Romania and Poland. We also aim at underlining positive and negative points for fiscal competition taking into consideration that not only a decrease in micro or macro-economic fiscal burden will have a positive impact upon investments in-flows and there are other factors to be taken into consideration, like: infrastructure, labor expenses

The Principle of Social Scaling

Directory of Open Access Journals (Sweden)

Paulo L. dos Santos

2017-01-01

Full Text Available This paper identifies a general class of economic processes capable of generating the first-moment constraints implicit in the observed cross-sectional distributions of a number of economic variables: processes of social scaling. Across a variety of settings, the outcomes of economic competition reflect the normalization of individual values of certain economic quantities by average or social measures of themselves. The resulting socioreferential processes establish systematic interdependences among individual values of important economic variables, which under certain conditions take the form of emergent first-moment constraints on their distributions. The paper postulates a principle describing this systemic regulation of socially scaled variables and illustrates its empirical purchase by showing how capital- and labor-market competition can give rise to patterns of social scaling that help account for the observed distributions of Tobin’s q and wage income. The paper’s discussion embodies a distinctive approach to understanding and investigating empirically the relationship between individual agency and structural determinations in complex economic systems and motivates the development of observational foundations for aggregative, macrolevel economic analysis.

Current rules and state of readiness of the competitive market

Campbell, B.

2001-01-01

The focus of this presentation was on the governance, operation and regulation of the Independent Market Operator (IMO) in a competitive electricity market in Ontario. The presentation also included an update on the progress toward market readiness and discussed the principles guiding government decision making, recognizing that it is government that holds the decision on the market opening date. The IMO has been running Ontario's bulk electric system for more than 50 years, overseeing its safe and reliable operation while balancing demand and supply. IMOs are also leading the drive to a competitive, deregulated wholesale electricity marketplace in Ontario. When open, IMOs will run the electricity spot market, collecting offers from suppliers and bids from purchasers to determine a spot market price for electricity which will reflect demand across the province. Rules and processes are being developed to ensure the Ontario marketplace will operate to benefit both consumers and producers. The four principles guiding governments in the opening of electricity markets are to protect consumers and offer more choice, ensure a strong business climate with a reliable supply of electricity, to protect the environment, and to support alternative sources of power

Assessing the Effectiveness of Competition Law Enforcement Policy in Relation to Cartels

Priit Mändmaa

2014-11-01

Full Text Available Despite the high fines for cartel infringements it is claimed that the current competition law enforcement lacks deterrent effect for the avoidance of cartel infringements and is procedurally fragile. This article analyses the current competition law enforcement policy in relation to cartels. More specifically, the article assesses the effectiveness of the policy in deterring the formation of cartels and pursuing the goals of competition law by analysing the theory of deterrence, case law, procedural norms, imposed fines and academic literature. The main conclusions are that wrong targets are aimed at under the deterrence principle, the proceedings are of a criminal law nature and require a separation of powers, and that the current level of fines does not pose a threat on the economy and continually fail to deter price-fixing.

Strategic Adjustment Capacity, Sustained Competitive Advantage, and Firm Performance: An Evolutionary Perspective on Bird Flocking and Firm Competition

Directory of Open Access Journals (Sweden)

Shou Chen

2017-01-01

Full Text Available Imitating the positioning rules in the bird flocking system, the strategic adjustment capacity is decomposed into three aspects, which are the organizational learning capacity from the top firms, the extent to which firms maintain or rely on the best operational capacity vector in history, and the ability to overcome the disadvantage while maintaining the advantage of the operational capacity vector from the previous years, respectively. Financial vectors are constructed to represent the results of corporate strategic adjustment and listed firms in the China A stock are chosen as the samples. As empirical analysis reveals, there is a positive correlation between the organizational learning capacity from the top firms and the firm performance and a U-shaped relation between the learning capability from the previous best operational capacity vector and the firm performance. However, no significant correlation between the inertia control ability of the current operational capacity vector of the firms and their performance improvement can be observed. This study verifies that the issue of corporate competitiveness and performance can be investigated by utilizing the principles of competition in nature. Moreover, a firm can obtain a sustainable competitive advantage by improving its ability to learn from top firms in the industry.

EdF, the historical operator, and GdF Suez the French number two of hydropower generation are going to face the strong competition of the big European energy groups. France will open 20% of its hydroelectric potential to competition in order to be in agreement with the opening of energy markets imposed by the European Union, and to increase by 10% the hydroelectric power as requested by the French government policy. The candidates will have to fulfill 3 criteria: investing to increase production, reducing the environmental impacts, and accepting the principle of paying fees. However, some of the French dams suffer from serious pathologies and the health of thousands of small dams remains unknown because of the lack of available data. (J.S.)

We present here the principle of soft magnetic tweezers which improve the traditional magnetic tweezers allowing the simultaneous application and measurement of an arbitrary torque to a deoxyribonucleic acid (DNA) molecule. They take advantage of a nonlinear coupling regime that appears when a fast rotating magnetic field is applied to a superparamagnetic bead immersed in a viscous fluid. In this work, we present the development of the technique and we compare it with other techniques capable of measuring the torque applied to the DNA molecule. In this proof of principle, we use standard electromagnets to achieve our experiments. Despite technical difficulties related to the present implementation of these electromagnets, the agreement of measurements with previous experiments is remarkable. Finally, we propose a simple way to modify the experimental design of electromagnets that should bring the performances of the device to a competitive level.

The logic of indirect speech

When people speak, they often insinuate their intent indirectly rather than stating it as a bald proposition. Examples include sexual come-ons, veiled threats, polite requests, and concealed bribes. We propose a three-part theory of indirect speech, based on the idea that human communication involves a mixture of cooperation and conflict. First, indirect requests allow for plausible deniability, in which a cooperative listener can accept the request, but an uncooperative one cannot react adversarially to it. This intuition is supported by a game-theoretic model that predicts the costs and benefits to a speaker of direct and indirect requests. Second, language has two functions: to convey information and to negotiate the type of relationship holding between speaker and hearer (in particular, dominance, communality, or reciprocity). The emotional costs of a mismatch in the assumed relationship type can create a need for plausible deniability and, thereby, select for indirectness even when there are no tangible costs. Third, people perceive language as a digital medium, which allows a sentence to generate common knowledge, to propagate a message with high fidelity, and to serve as a reference point in coordination games. This feature makes an indirect request qualitatively different from a direct one even when the speaker and listener can infer each other's intentions with high confidence. PMID:18199841

Sudan dyes are banned to be used in food additives because of the carcinogenicity of their metabolites. A rapid and sensitive indirect competitive enzyme-linked immunosorbent assay (ELISA) was developed to detect the residues of Sudan dyes. Novel immunogen and coating antigen were synthesized via glutaraldehyde linking. The hapten-bovine serum albumin (BSA) was applied as immunogen and the hapten-ovalbumin (OVA) was served as coating antigen. The monoclonal antibody obtained showed high sensitivity to Sudan I with an IC(50) value of 1.7 μg L(-1) in buffer and was suitable to detect the residues of Sudan red in food products. The specificity of the assay was studied by measuring cross-reactivity of the antibody with the structurally related compounds of Sudan II (red (120%). Chilli jam and chilli oil samples spiked with Sudan dyes were analyzed by the method. The detection limit (LOD) of the ELISA method applied in chilli jam and chilli oil was 9.0 μg L(-1) and 19.6 μg L(-1), respectively. The recovery rates of Sudan-I in chilli oil and chilli jam were in the range of 80%-110% with coefficients of variation <25%. The intra-assay variation and inter-assay variation in buffer were both <9%.

Cell Competition is an interaction between cells for existence in heterogeneous cell populations of multicellular organisms. This phenomenon is involved in initiation and progression of cancer where heterogeneous cell populations compete directly or indirectly for the survival of the fittest based on differential gene expression. In Drosophila, cells having lower dMyc expression are eliminated by cell competition through apoptosis when present in the milieu of cells having higher dMyc expression. Thus, we designed a study to develop c-Myc (human homolog) dependent in vitro cell competition model of human cancer cells. Cells with higher c-Myc were transfected with c-myc shRNA to prepare cells with lower c-Myc and then co-cultured with the same type of cells having a higher c-Myc in equal ratio. Cells with lower c-Myc showed a significant decrease in numbers when compared with higher c-Myc cells, suggesting "loser" and "winner" status of cells, respectively. During microscopy, engulfment of loser cells by winner cells was observed with higher expression of JNK in loser cells. Furthermore, elimination of loser cells was prevented significantly, when co-cultured cells were treated with the JNK (apoptosis) inhibitor. Above results indicate elimination of loser cells in the presence of winner cells by c-Myc-dependent mechanisms of cell competition in human cancer cells. This could be an important mechanism in human tumors where normal cells are eliminated by c-Myc-overexpressed tumor cells. J. Cell.

Sum of energy released by the wave force in shock tube is a pre-condition for operation of the new detonator, and measurement of wave force is the first step in determining the sum of energy. The sum of energy is measured indirectly, based on two principles: movement sensors and strain.

Modelling the co-evolution of indirect genetic effects and inherited variability.

When individuals interact, their phenotypes may be affected not only by their own genes but also by genes in their social partners. This phenomenon is known as Indirect Genetic Effects (IGEs). In aquaculture species and some plants, however, competition not only affects trait levels of individuals, but also inflates variability of trait values among individuals. In the field of quantitative genetics, the variability of trait values has been studied as a quantitative trait in itself, and is often referred to as inherited variability. Such studies, however, consider only the genetic effect of the focal individual on trait variability and do not make a connection to competition. Although the observed phenotypic relationship between competition and variability suggests an underlying genetic relationship, the current quantitative genetic models of IGE and inherited variability do not allow for such a relationship. The lack of quantitative genetic models that connect IGEs to inherited variability limits our understanding of the potential of variability to respond to selection, both in nature and agriculture. Models of trait levels, for example, show that IGEs may considerably change heritable variation in trait values. Currently, we lack the tools to investigate whether this result extends to variability of trait values. Here we present a model that integrates IGEs and inherited variability. In this model, the target phenotype, say growth rate, is a function of the genetic and environmental effects of the focal individual and of the difference in trait value between the social partner and the focal individual, multiplied by a regression coefficient. The regression coefficient is a genetic trait, which is a measure of cooperation; a negative value indicates competition, a positive value cooperation, and an increasing value due to selection indicates the evolution of cooperation. In contrast to the existing quantitative genetic models, our model allows for co-evolution of

Full Text Available In this work we focused on summarizing the principles of green marketing and the concepts related to it. The aim of this contribution was to prove the relationship between the implementation of green marketing principles and sustainable competitive company position on the market. In order to prove the relationship between the implementation of green marketing principles and the competitive market position of companies, we used a multiple regression method to reveal the relationship, despite many variables. This was preceded by a factor analysis that helped us to select the main factors of influence. In order to meet this goal, we have drawn from the surveys conducted by PwC (Bratislava, Slovakia, the Automobile Industry Association and the Slovak Automobile Institute to identify key factors and future expected development in the auto industry supplier segment and our marketing research, conducted from December 2015 to February 2016. Based on the results of marketing surveys, research responses and the study of available resources, we concluded that there is no comprehensive green marketing implementation model linking environmental consumer behavior with a link to the company’s marketing strategy. The contribution could help the Automotive Industry Union to present requirements to the government and help create incentives for the alternative vehicle market, and our findings could be incorporated into the creation of companies’ strategy.

1. Physics competitions: aims and realizations One aim of physics competitions is to increase the interest of young students, primarily at upper secondary level, to physics and natural sciences in general. A competition has motivational aspects known usually from sports events or games—comparing one's own ability with others, of course with the desire to be better and to win. If competitions reach nationwide and even international levels, additional stimulation is created. Competitions provide greatest attraction to possible winners, to the group of gifted people in a particular field. This implies that science contests are excellent tools for the promotion of talented students. Traditional teaching has been shown to have problems in supporting this group of students. Very often teachers are overstretched with the demands of teaching both low- and high-level students. Extracurricular activities are therefore a good chance to relieve the teacher, and to give talented students the opportunity for appropriate training and challenge. The competitions, however, have a broader impact and address more young people than one might guess from the statements above. Training courses and selection at school level give a larger group of students extra and, to some extent, complimentary education in physics. The degree of complexity of the tasks corresponds very often to the standards of the next level of education in the school system. Interestingly, many physics competitions have their origin in countries beyond the former Iron Curtain. They started as regional and national tournaments, were joined by neighbouring countries and have grown, in some cases, to events with participants from more than 80 countries. Although the features mentioned above are common to the different competitions, there are distinct differences between them [1]. The International Physics Olympiad (IPhO) is the oldest international physics competition for students at upper secondary level [2]. It dates

Full Text Available With the advent of lingual orthodontics, indirect bonding technique has become an integral part of practice. It involves placement of brackets initially on the models and then their transfer to teeth with the help of transfer trays. Problems encountered with current indirect bonding techniques used are (1 the possibility of adhesive flash remaining around the base of the brackets which requires removal (2 longer time required for the adhesive to gain enough bond strength for secure tray removal. The new simplified indirect bonding technique presented here overcomes both these problems.

Personal competitiveness and competitive orientations – priority quality of future expert for successful future professional experience.The aim of the present research is to study factors of competitive orientations formation and criteria for evaluation of competitiveness of student’s youth in the Russian society.Methodology and research methods. Results of theoretical researches of Russian and foreign researchers are generalized; secondary analysis of data based on results of sociological researches and analysis of official statistical data are carried out. The results of the sociological survey undertaken in 2017 on the basis of statistical methods were processed and studied by the instrumentality of IBM SPSS Statistics 23 program; 1196 students of institutions of higher and secondary vocational education of the Tyumen region took part.Results and scientific novelty. It is stated that senior students feel themselves more competitive. It is revealed that a quarter of students who took part in the survey, generally men, count themselves competitive. A continuous distance of goal-setting is recorded among these respondents; in every third case they have plans of professional growth for five and more years that allows them to build attractive competitive strategy.The level of the competitiveness is directly connected with such indicators as “social stratum”, “overall life satisfaction”, “self-esteem of health”, “tendency to lead a healthy lifestyle” and “the level of trust in the surrounding people”. Mostly the students oriented on competition look into the future with confidence and optimism.Respondents focused on the competitiveness were more tend to demonstrate their abilities and cause admiration, have a creative approach towards work, be ready for surprises

Co-evolution of the brand effect and competitiveness in evolving networks

The principle that ‘the brand effect is attractive’ underlies the preferential attachment. Here we show that the brand effect is just one dimension of attractiveness. Another dimension is competitiveness. We firstly introduce a general framework that allows us to investigate the competitive aspect of real networks, instead of simply preferring popular nodes. Our model accurately describes the evolution of social and technological networks. The phenomenon that more competitive nodes become richer can help us to understand the evolution of many competitive systems in nature and society. In general, the paper provides an explicit analytical expression of degree distributions of the network. In particular, the model yields a nontrivial time evolution of nodes' properties and the scale-free behavior with exponents depending on the microscopic parameters characterizing the competition rules. Secondly, through theoretical analyses and numerical simulations, we reveal that our model has not only the universality for the homogeneous weighted network, but also the character for the heterogeneous weighted network. Thirdly, we also develop a model based on the profit-driven mechanism. It can better describe the observed phenomenon in enterprise cooperation networks. We show that the standard preferential attachment, the growing random graph, the initial attractiveness model, the fitness model, and weighted networks can all be seen as degenerate cases of our model.

Full Text Available commerce. The commercial activity is, from a legal perspective, a correct exercise of the ownership and free initiative by the legal person in the commercial activities, the business conduct being necessary to circumscribe the legal rules that govern the commercial market. This article has as starting point on the one hand the need for legal provisions ensuring a real protection to the Romanian consumers exposed to unfair trade practices, and on the other hand of some comprehensive legal stipulations on tradesmen’s contravention and criminal liability that show an unfair competitive conduct. The general regulatory framework regarding the unfair competition consists of the Law no. 11/1991 on combating the unfair competition, the legal stipulations which relate to the European provisions on the matter, namely the Directive 2005/29/EC of the European Parliament and of the Council from May 11th 2005 concerning unfair commercial practices of enterprises in the internal market to consumers and amending the Directive 84/450/EEC of the Council, of the Directives 97/7/EC, 98/27/EC and 2002/65/EC of the European Parliament and of the Council and Regulation (EC no. 2006/2004 of the European Parliament and of the Council. The European legislation includes the stipulations regarding the unfair commercial practices prohibited in the E.U. space, as well as the stipulations relating to the economic interests of consumers who enter into transactions with tradesmen. In this respect, the European regulations deem unfair trade practices those acts or actions that violate the principles of professional diligence and which may influence the commercial decisions of consumers, being categorized as misleading practices and aggressive commercial practices. In accordance with the provisions of the Law no. 11/1991 on combating the unfair competition, with the ulterior amendments and supplements, unfair competition represents the commercial practices of the enterprise

Vaillancourt, Tracy; Sharma, Aanchal

Intrasexual competition among males of different species, including humans, is well documented. Among females, far less is known. Recent nonexperimental studies suggest that women are intolerant of attractive females and use indirect aggression to derogate potential rivals. In Study 1, an experimental design was used to test the evolutionary-based hypothesis that women would be intolerant of sexy women and would censure those who seem to make sex too readily available. Results provide strong empirical support for intrasexual competition among women. Using independent raters, blind to condition, we found that almost all women were rated as reacting negatively ("bitchy") to an attractive female confederate when she was dressed in a sexually provocative manner. In contrast, when she was dressed conservatively, the same confederate was barely noticed by the participants. In Study 2, an experimental design was used to assess whether the sexy female confederate from Study 1 was viewed as a sexual rival by women. Results indicated that as hypothesized, women did not want to introduce her to their boyfriend, allow him to spend time alone with her, or be friends with her. Findings from both studies are discussed in terms of evolutionary theory. © 2011 Wiley Periodicals, Inc.

One principle that the electricity sector must fulfil is to simultaneously guarantee generation free entrance, new and old demand supply and a harmonic network development. This development is contained in the grid planning, a process assumed by a neutral institution apart from the grid or the interests of the market agents: In the case of Spain the ministry. The development of such planning, the investment to be built, are limited by the physical network and formal structure and by how the retribution is designed. In this article there is an evaluation of the problems related to develop the network planning in a competitive environment and also some proposals are suggested. (Author)

Fundamental uncertainty limit of optical flow velocimetry according to Heisenberg's uncertainty principle.

Science.gov (United States)

Fischer, Andreas

2016-11-01

Optical flow velocity measurements are important for understanding the complex behavior of flows. Although a huge variety of methods exist, they are either based on a Doppler or a time-of-flight measurement principle. Doppler velocimetry evaluates the velocity-dependent frequency shift of light scattered at a moving particle, whereas time-of-flight velocimetry evaluates the traveled distance of a scattering particle per time interval. Regarding the aim of achieving a minimal measurement uncertainty, it is unclear if one principle allows to achieve lower uncertainties or if both principles can achieve equal uncertainties. For this reason, the natural, fundamental uncertainty limit according to Heisenberg's uncertainty principle is derived for Doppler and time-of-flight measurement principles, respectively. The obtained limits of the velocity uncertainty are qualitatively identical showing, e.g., a direct proportionality for the absolute value of the velocity to the power of 32 and an indirect proportionality to the square root of the scattered light power. Hence, both measurement principles have identical potentials regarding the fundamental uncertainty limit due to the quantum mechanical behavior of photons. This fundamental limit can be attained (at least asymptotically) in reality either with Doppler or time-of-flight methods, because the respective Cramér-Rao bounds for dominating photon shot noise, which is modeled as white Poissonian noise, are identical with the conclusions from Heisenberg's uncertainty principle.

The seminal importance of detecting ions and molecules for point-of-care tests has driven the search for more sensitive, specific, and robust sensors. Electronic detection holds promise for future miniaturized in-situ applications and can be integrated into existing electronic manufacturing processes and technology. The resulting small devices will be inherently well suited for multiplexed and parallel detection. In this review, different field-effect transistor (FET) structures and detection principles are discussed, including label-free and indirect detection mechanisms. The fundamental detection principle governing every potentiometric sensor is introduced, and different state-of-the-art FET sensor structures are reviewed. This is followed by an analysis of electrolyte interfaces and their influence on sensor operation. Finally, the fundamentals of different detection mechanisms are reviewed and some detection schemes are discussed. In the conclusion, current commercial efforts are briefly considered.

Indirect fluorometric detection techniques on thin layer chromatography and effect of ultrasound on gel electrophoresis

Energy Technology Data Exchange (ETDEWEB)

Yinfa, Ma.

1990-12-10

Thin-layer chromatography (TLC) is a broadly applicable separation technique. It offers many advantages over high performance liquid chromatography (HPLC), such as easily adapted for two-dimensional separation, for whole-column'' detection and for handling multiple samples, etc. However, due to its draggy development of detection techniques comparing with HPLC, TLC has not received the attention it deserves. Therefore, exploring new detection techniques is very important to the development of TLC. It is the principal of this dissertation to present a new detection method for TLC -- indirect fluorometric detection method. This detection technique is universal sensitive, nondestructive, and simple. This will be described in detail from Sections 1 through Section 5. Section 1 and 3 describe the indirect fluorometric detection of anions and nonelectrolytes in TLC. In Section 2, a detection method for cations based on fluorescence quenching of ethidium bromide is presented. In Section 4, a simple and interesting TLC experiment is designed, three different fluorescence detection principles are used for the determination of caffeine, saccharin and sodium benzoate in beverages. A laser-based indirect fluorometric detection technique in TLC is developed in Section 5. Section 6 is totally different from Sections 1 through 5. An ultrasonic effect on the separation of DNA fragments in agarose gel electrophoresis is investigated. 262 refs.

Indirect Reciprocity; A Field Experiment.

Indirect reciprocity involves cooperative acts towards strangers, either in response to their kindness to third parties (downstream) or after receiving kindness from others oneself (upstream). It is considered to be important for the evolution of cooperative behavior amongst humans. Though it has been widely studied theoretically, the empirical evidence of indirect reciprocity has thus far been limited and based solely on behavior in laboratory experiments. We provide evidence from an online environment where members can repeatedly ask and offer services to each other, free of charge. For the purpose of this study we created several new member profiles, which differ only in terms of their serving history. We then sent out a large number of service requests to different members from all over the world. We observe that a service request is more likely to be rewarded for those with a profile history of offering the service (to third parties) in the past. This provides clear evidence of (downstream) indirect reciprocity. We find no support for upstream indirect reciprocity (in this case, rewarding the service request after having previously received the service from third parties), however. Our evidence of downstream indirect reciprocity cannot be attributed to reputational effects concerning one's trustworthiness as a service user.

Pedal indirect lymphangiography

Recently, indirect lymphangiography has been developed as a relatively good and noninvasive imaging modality of the lymphatic system at extremities. But the disadvantage of the indirect lymphangiography is a low contrast ratio between the surrounding tissues and the contrast media in lymphatic vessels, because dimeric nonionic contrast media is water soluble and diluted in the proximal leg lymphatic vessels. We could have relatively better image than previously published images for the leg lymphatic system, when we injected contrast media with adequate high pressure in intradermal space of the interdigital areas at the foot dorsum. So, we would like to report the results. We could study all 9 lymphedemas(primary: 6, secondary: 3) from April 1990 to May 1993 on outpatient base. They were diagnosed as lymphedema clinically and radiologically. Ten ml of dimeric nonionic aget, iotrolan(Isovist 300) was injected into intradermal space with five 30-gauge needles. The injection speed was more than 0.2 ml/min. We have done one side pedal lymphangiogram in 30 minutes. The evaluation of the anterior superficial lymphatics was according to the criteria of the Weissleder. The results were as follows: 1. All lymphatic vessels from foot to inguinal area could be visualized. 2. Two or three inferior inguinal lymph nodes could be visualized about 42%. 3. The most common abnormal finding of the lymphedma was the neovascularization of the lymphatics on indirect pedal lymphangiogram. If we use adequate technique relatively high pressure injection, correct intradermal needle insertion, adequate soft tissue exposure technique indirect lymphangiography is considered to be a safe and noninvasive imaging modality for the evaluation of the lymphedema of lower extremity lymphatics including inferior inguinal lymph nodes

Seeing Cooperation or Competition: Ecological Interactions in Cultural Perspectives.

Do cultural models facilitate particular ways of perceiving interactions in nature? We explore variability in folkecological principles of reasoning about interspecies interactions (specifically, competitive or cooperative). In two studies, Indigenous Panamanian Ngöbe and U.S. participants interpreted an illustrated, wordless nonfiction book about the hunting relationship between a coyote and badger. Across both studies, the majority of Ngöbe interpreted the hunting relationship as cooperative and the majority of U.S. participants as competitive. Study 2 showed that this pattern may reflect different beliefs about, and perhaps different awareness of, plausible interspecies interactions. Further probes suggest that these models of ecological interaction correlate with recognition of social agency (e.g., communication, morality) in nonhuman animals. We interpret our results in terms of cultural models of nature and nonhuman agency. Copyright © 2015 Cognitive Science Society, Inc.

It is concluded that the chemical industry is one of the EU’s most successful spheres, boasting €527 billion in sales in 2013, making it the second-largest global manufacture. Methodology. To explain the competitiveness of the EU chemical branch in the global market, it is proposed the constant-market share methodology to chemical exports coupled with econometric analysis. Results. The constant market share (CMS approach to assessing competitiveness, developed in the 1970 s for analysis of trade, is based on the principle that changes in the geographic and product structures of exports will affect a country’s export growth relative to that of the world, and that is way its global export market share. There were analyzed the EU biggest exporters (Germany, France, Italy, UK, Spain, Netherlands, Belgium, Poland, the USA, Japan; China, India, Saudi Arabia, Brazil. Practical implication. The analysis presents the results of competitiveness assessment in a different way, showing the average annual growth rate of EU and world chemical exports in the top section and then decomposing the gap between the two into that thanks to growth dynamics (structure effect and competitive effect. It is defined a lot of factors that are important to industrial competitiveness. On the cost side, in many industries labor is a large enough share of overall production costs that international differences in salaries can have a large bearing on competitiveness. Costs are also affected by a variety of government policies. It is also defined that innovation is one of the most important factors, which opens up new opportunities both in terms of new products and more efficient processes for manufacturing existing products.

*Here, we analysed the role of direct and indirect plant interactions in the invasion process of Acer negundo along a natural successional gradient in the Middle Rhone floodplain (France). We addressed two questions: What are the responses of the invasive Acer seedlings to native communities' effects along the successional gradient? What are the effects of the invasive Acer adult trees on the native communities? *In the three communities (Salix, Acer and Fraxinus stands) we transplanted juveniles of the invasive and juveniles of the natives within the forest and in experimental gaps, and with and without the herb layer. We also quantified changes in understory functional composition, light, nitrogen and moisture among treatments. *Acer seedlings were directly facilitated for survival in the Salix and Acer communities and indirectly facilitated for growth by adult Acer through the reduction of the abundance of highly competitive herbaceous competitors. *We conclude that direct facilitation by the tree canopy of the native pioneer Salix is very likely the main biotic process that induced colonization of the invasive Acer in the floodplain and that indirect facilitation by adult conspecifics contributed to population establishment.

Characteristic Features of Publications on Architectural Competition Practice in Latvia, 1859–2013

Full Text Available The competition practice has been rather extensively published, as publications on architectural competitions are inseparable from the competition process itself. They are a significant part of representation that explicitly promotes understanding of the design, realization and implementation process, and are a way to communicate the project to the client, jury, community and authorities. Yet, there have always been insufficient consistent critical discussions on the architecture and planning discourse in Latvia, neither on competitions, nor on the related publications. The purpose of the paper is to distinguish features that characterize publications on architectural competitions in Latvia. Methodological principles and systematization of the materials have been carried out according to the historical and logical approach method based on studies of the collected examples and sources of over 1,000 publications on 960 competitions of the past 160 years. The paper systematizes publications on competition practice over the several time periods in Latvia (Russian Empire 1859–1918, Independence 1918–34, Authoritarian Regime 1934–40, Soviet Period 1940–90 and the Second Independence 1991–2013 according to their topics, the author’s professional profiles, type and content and, eventually their characteristic style. Insights into the development of local competition practice through related publications help to explain the formation of a significant part of the local architectural and urban discourse, as its understanding is partially determined by the plurality of representations and interpretations.

Supersymmetric dark matter: Indirect detection

International Nuclear Information System (INIS)

Bergstroem, L.

2000-01-01

Dark matter detection experiments are improving to the point where they can detect or restrict the primary particle physics candidates for non baryonic dark matter. The methods for detection are usually categorized as direct, i.e., searching for signals caused by passage of dark matter particles in terrestrial detectors, or indirect. Indirect detection methods include searching for antimatter and gamma rays, in particular gamma ray lines, in cosmic rays and high-energy neutrinos from the centre of the Earth or Sun caused by accretion and annihilation of dark matter particles. A review is given of recent progress in indirect detection, both on the theoretical and experimental side

INDIRECT LABOR COSTS AND IMPLICATIONS FOR OVERHEAD ALLOCATION

OpenAIRE

Bea Chiang

2013-01-01

Cost accounting typically allocates indirect labor cost to cost object based on direct labor hours. The allocation process implicitly assumes that indirect labor costs vary proportionally with direct labor hours. The assumption of a linear relationship between indirect and direct labor is particularly suspicious at low production volume levels because there tends to be a fixed component in indirect labor. The linearity assumption is also challenged by recent increasing complexity of indirect ...

Full Text Available This research is conducted to examine the influence of market attractiveness and dynamic capability on strategic competitive response through overall logistics strategies of logistics service providers LSPs. Involving 266 LSPs SEM-LISREL is applied to test the hypotheses. The findings reveal that the market attractiveness and the dynamic capability positively affect the overall logistics strategy. Additionally the market attractiveness and the dynamic capability positively affect the strategic competitive response. Indirectly the market attractiveness and the dynamic capability positively affect the performance through strategic competitive response of LSPs. Obviously overall logistics strategy strengthen the influence of both market attractiveness and dynamic capability on strategic competitive response. There are five alternatives to optimize the overall logistics strategy of LSPs market intensification integration focus collaboration and strengthening value proposition. The involvement of overall logistics strategy as mediating variable is new paradigm in the strategic management discourses especially in logistics industry. Further research needs to be performed by involving the size of business as control variable and LSPs perception on Governments policies.

The purpose of this thesis is to discuss both phenomenological and experimental aspects of Dark Matter, related to its indirect detection with gamma-ray astronomy. In the MSSM framework, neutralinos arise as natural candidates to non-baryonic and Cold Dark Matter, whose gravitational effects manifest in the Universe at different scales. As they are Majorana particles, they may in principle annihilate in high density regions, as the centres of galaxies, and produce gamma rays. Nevertheless, the expected fluxes are basically low compared to experimental sensitivities. After estimating gamma fluxes from M31 and Draco galaxies in the MSSM scheme, we first generalize the MSSM couplings by studying an effective Lagrangian. We show that the only constraint of imposing a relic abundance compatible with recent measurements obviously deplete significantly the gamma ray production, but also that predictions in this effective approach are more optimistic for indirect detection than the MSSM. In a second part, we present the indirect searches for Dark Matter performed with the CELESTE Cherenkov telescope towards the galaxy M31. We propose a statistical method to reconstruct spectra, mandatory to discriminate classical and exotic spectra. The M31 data analysis enables the extraction of an upper limit on the gamma ray flux, which is the first worldwide for a galaxy in the energy range 50-500 GeV, and whose astrophysical interest goes beyond indirect searches for Dark Matter.

Science.gov (United States)

Gao, Xiang; Li, Chao; Fang, Guangyou

2013-06-01

In this paper, an indirect holographic image reconstruction algorithm was studied for terahertz imaging with a quasi-optics receiver. Based on the combination of the reciprocity principle and modified quasi-optics theory, analytical expressions of the received spatial power distribution and its spectrum are obtained for the interference pattern of target wave and reference wave. These results clearly give the quantitative relationship between imaging quality and the parameters of a Gaussian beam, which provides a good criterion for terahertz quasi-optics transceivers design in terahertz off-axis holographic imagers. To validate the effectiveness of the proposed analysis method, some imaging results with a 0.3 THz prototype system are shown based on electromagnetic simulation.

Common region wins the competition between extrinsic grouping cues: Evidence from a task without explicit attention to grouping.

The competition between perceptual grouping factors is a relatively ignored topic, especially in the case of extrinsic grouping cues (e.g., common region or connectedness). Recent studies have examined the integration of extrinsic cues using tasks that induce selective attention to groups based on different grouping cues. However, this procedure could generate alternative strategies for task performance, which are non-related to the perceptual grouping operations. In the current work, we used an indirect task, i.e. repetition discrimination task, without explicit attention to grouping cues to further examine the rules that govern dominance between competing extrinsic grouping factors. This procedure allowed us to obtain an unbiased measure of the competition between common region and connectedness cues acting within the same display. The results corroborate previous data showing that grouping by common region dominated the perceived organization of the display, even though the phenomenological strength of the grouping cues was equated for each participant by means of a preliminary scaling task. Our results highlight the relevance of using indirect tasks as an essential tool for the systematic study of the integration of extrinsic grouping cues.

Co-evolution of the brand effect and competitiveness in evolving networks

International Nuclear Information System (INIS)

Guo Jin-Li

2014-01-01

The principle that ‘the brand effect is attractive’ underlies the preferential attachment. Here we show that the brand effect is just one dimension of attractiveness. Another dimension is competitiveness. We firstly introduce a general framework that allows us to investigate the competitive aspect of real networks, instead of simply preferring popular nodes. Our model accurately describes the evolution of social and technological networks. The phenomenon that more competitive nodes become richer can help us to understand the evolution of many competitive systems in nature and society. In general, the paper provides an explicit analytical expression of degree distributions of the network. In particular, the model yields a nontrivial time evolution of nodes' properties and the scale-free behavior with exponents depending on the microscopic parameters characterizing the competition rules. Secondly, through theoretical analyses and numerical simulations, we reveal that our model has not only the universality for the homogeneous weighted network, but also the character for the heterogeneous weighted network. Thirdly, we also develop a model based on the profit-driven mechanism. It can better describe the observed phenomenon in enterprise cooperation networks. We show that the standard preferential attachment, the growing random graph, the initial attractiveness model, the fitness model, and weighted networks can all be seen as degenerate cases of our model.

Khodyakova Olga V.

2014-01-01

Full Text Available The goal of the article is analysis of the structure and dynamics of indirect taxes for the previous five years and also the influence of indirect taxation upon formation of income of the State Budget of Ukraine. The article analyses the modern state of indirect taxation in Ukraine. Specific weight of the value added tax, excise tax and customs duty are considered in the structure of tax receipts of the consolidated budget of Ukraine as indirect taxes. The article shows that receipts of the State Budget of Ukraine are mostly provided by indirect taxes. The Ukrainian taxation system is mostly a factor of reduction of the level of economic growth and investment activity in the country and the existing system of administering is not completely capable of excluding the possibility of tax evasion. The prospect of further studies in this direction is improvement of organisation of tax control in Ukraine and differentiation of the value added tax rates depending on the level of consumption of goods and level of income of consumers.

Benign vocal fold nodules affect 12% to 22% of the pediatric population, and 95% of otolaryngologists recommend voice therapy as treatment. However, no randomized clinical trials that we are aware of have shown its benefits. To determine the impact of voice therapy in children with vocal fold nodules according to pretherapy and posttherapy scores on the Pediatric Voice-Related Quality of Life (PVRQOL) survey; secondary objectives included changes in phonatory parameters. For this multicenter randomized clinical trial, 114 children ages 6 to 10 years with vocal fold nodules, PVRQOL scores less than 87.5, and dysphonia for longer than 12 weeks were recruited from outpatient voice and speech clinics. This age range was identified because these patients have not experienced pubertal changes of the larynx, tolerate stroboscopy, and cooperate with voice therapy. Participants were blinded to treatment arm. Participants received either indirect or direct therapy for 8 to 12 weeks. Indirect therapy focused on education and discussion of voice principles, while direct treatment used the stimulus, response, antecedent paradigm. The primary outcome measure was PVRQOL score change before and after treatment. Secondary phonatory measures were also compared. Overall, 114 children were recruited for study (mean [SD] age, 8 [1.4] years; 83 males [73%]); with 57 randomized to receive either indirect or direct therapy. Both direct and indirect therapy approaches showed significant differences in PVRQOL scores pretherapy to posttherapy. The mean increase in PVRQOL score for direct therapy was 19.2, and 14.7 for indirect therapy (difference, 4.5; 95.3% CI, -10.8 to 19.8). Of 44 participants in the direct therapy group, 27 (61%) achieved a clinically meaningful PVRQOL improvement, compared with 26 of 49 (53%) for indirect therapy (difference, 8%; 95% CI, -12 to 28). Post hoc stratification showed robust effects in the direct therapy group for older children (Cohen d = 0.50) and the

A new hammer to crack an old nut: interspecific competitive resource capture by plants is regulated by nutrient supply, not climate.

2012-01-01

Although rarely acknowledged, our understanding of how competition is modulated by environmental drivers is severely hampered by our dependence on indirect measurements of outcomes, rather than the process of competition. To overcome this, we made direct measurements of plant competition for soil nitrogen (N). Using isotope pool-dilution, we examined the interactive effects of soil resource limitation and climatic severity between two common grassland species. Pool-dilution estimates the uptake of total N over a defined time period, rather than simply the uptake of ¹⁵N label, as used in most other tracer experiments. Competitive uptake of N was determined by its available form (NO₃⁻ or NH₄⁺). Soil N availability had a greater effect than the climatic conditions (location) under which plants grew. The results did not entirely support either of the main current theories relating the role of competition to environmental conditions. We found no evidence for Tilman's theory that competition for soil nutrients is stronger at low, compared with high nutrient levels and partial support for Grime's theory that competition for soil nutrients is greater under potentially more productive conditions. These results provide novel insights by demonstrating the dynamic nature of plant resource competition.

Indirect Reciprocity under Incomplete Observation

Nakamura, Mitsuhiro; Masuda, Naoki

2011-01-01

Indirect reciprocity, in which individuals help others with a good reputation but not those with a bad reputation, is a mechanism for cooperation in social dilemma situations when individuals do not repeatedly interact with the same partners. In a relatively large society where indirect reciprocity is relevant, individuals may not know each other's reputation even indirectly. Previous studies investigated the situations where individuals playing the game have to determine the action possibly without knowing others' reputations. Nevertheless, the possibility that observers of the game, who generate the reputation of the interacting players, assign reputations without complete information about them has been neglected. Because an individual acts as an interacting player and as an observer on different occasions if indirect reciprocity is endogenously sustained in a society, the incompleteness of information may affect either role. We examine the game of indirect reciprocity when the reputations of players are not necessarily known to observers and to interacting players. We find that the trustful discriminator, which cooperates with good and unknown players and defects against bad players, realizes cooperative societies under seven social norms. Among the seven social norms, three of the four suspicious norms under which cooperation (defection) to unknown players leads to a good (bad) reputation enable cooperation down to a relatively small observation probability. In contrast, the three trustful norms under which both cooperation and defection to unknown players lead to a good reputation are relatively efficient. PMID:21829335

Direct and Indirect Effects of Climate Change on Amphibian Populations

Directory of Open Access Journals (Sweden)

Stephanie S. Gervasi

2010-02-01

Full Text Available As part of an overall decline in biodiversity, populations of many organisms are declining and species are being lost at unprecedented rates around the world. This includes many populations and species of amphibians. Although numerous factors are affecting amphibian populations, we show potential direct and indirect effects of climate change on amphibians at the individual, population and community level. Shifts in amphibian ranges are predicted. Changes in climate may affect survival, growth, reproduction and dispersal capabilities. Moreover, climate change can alter amphibian habitats including vegetation, soil, and hydrology. Climate change can influence food availability, predator-prey relationships and competitive interactions which can alter community structure. Climate change can also alter pathogen-host dynamics and greatly influence how diseases are manifested. Changes in climate can interact with other stressors such as UV-B radiation and contaminants. The interactions among all these factors are complex and are probably driving some amphibian population declines and extinctions.

Comparison of monomeric and polymeric horseradish peroxidase as labels in competitive ELISA for small molecule detection

Li, Dongyang; Ying, Yibin; Wu, Jian; Niessner, Reinhard; Knopp, Dietmar

2013-01-01

We have developed a simple and sensitive competitive enzyme-linked immunosorbent assay (ELISA) to determine aflatoxin B1 (as a model small analyte) and using streptavidin-polymeric horseradish peroxidase complex (SApolyHRP) as a label for signal amplification. The performance of the assay was evaluated by comparing it with the classical indirect competitive ELISA using HRP labeled anti-mouse IgG as the tracer antibody. The results indicate that the SApolyHRP-based competitive ELISA exhibits a typically 2.4-fold steeper slope of the linear working range of the calibration curve compared to the monomeric HRP based classical ELISA, i.e., the sensitivity was increased. The SApolyHRP conjugate causes a typically 19-fold stronger signal generation in comparison to the traditional HRP labeled anti-mouse IgG at the same concentration (25 ng mL −1 ). Moreover, the SApolyHRP-based assay has a much wider linear range and a 3.8-fold better signal-to-noise ratio. Considering its simplicity, sensitivity and ease of operation, this competitive ELISA is considered to be a promising tool for small molecule immuno detection. (author)

The Antidiscrimination Principle and the Determination of Disadvantage

MARÍA JOSÉ AÑÓN

2014-06-01

Full Text Available This paper examines some of the limits of antidiscrimination law in its present form, focusing on the major trends that underlie it from the perspective of legislation and case law. It reflects on the traditional principles of interpretation and the impediments to incorporating standards offering both justification and explanation in the test of equality; standards that might detect the patterns or social structures of discrimination and identify individuals with greater accuracy. To this end, it proposes to further develop the debate on indirect discrimination and material equality through additional interpretative criteria that originate in categories such as structural discrimination and the intersectionality of discrimination.

Human Capital - A Quality Factor For The Competitiveness Of IT Companies

Directory of Open Access Journals (Sweden)

Elisei Crăciun

2015-05-01

Full Text Available This paper treats quality, human capital and competitiveness concepts in order to determine in which measure the Human Capital quality influences the competitiveness of a firm. The human capital theory is a relatively new approach, the first valuable approach being that of Garry Becker which, subsequent of the modern management theoretical views, puts human capital into scientific frame. This present paper relates deeply on this theoretical frame as it is considered that, besides financial or tangible resources that allows and generate long term benefits for an enterprise, there is also another source that consists in an intangible form: the human capital. This resource is based on education and health, indirectly generating additional benefits for the individual as for the organization and is calculated as instruction, education and health insurances costs. That implies that this capital is an asset for the worker itself and that the worker cannot be distinguished from the knowledges, capacities, his health or his values. From this perspective, the worker is actively present in any activity a firm operates: from defining and executing process, operational planning, monitoring and control, research and development, human resources, etc. The hypothesis of this present paper will be explored with the examples of Jeff Bezos ( Amazon or Steve Jobs ( Apple as human capital is considered to be the most important component for the competitive advantage of IT enterprises. The quality level of the human capital represents the main source for long term sustainability of this competitive advantage and, given the best case practices, it’s impact on firm’s effect indicators is obvious. The paper will also emphasize the role of values and health as they are also the main issues on an IT enterprise. The article is structured in two parts. One is the theoretical frame that encompass the influence of the human capital on the competitiveness of the firm. The

An Indirect Route for Ethanol Production

Energy Technology Data Exchange (ETDEWEB)

Eggeman, T.; Verser, D.; Weber, E.

2005-04-29

The ZeaChem indirect method is a radically new approach to producing fuel ethanol from renewable resources. Sugar and syngas processing platforms are combined in a novel way that allows all fractions of biomass feedstocks (e.g. carbohydrates, lignins, etc.) to contribute their energy directly into the ethanol product via fermentation and hydrogen based chemical process technologies. The goals of this project were: (1) Collect engineering data necessary for scale-up of the indirect route for ethanol production, and (2) Produce process and economic models to guide the development effort. Both goals were successfully accomplished. The projected economics of the Base Case developed in this work are comparable to today's corn based ethanol technology. Sensitivity analysis shows that significant improvements in economics for the indirect route would result if a biomass feedstock rather that starch hydrolyzate were used as the carbohydrate source. The energy ratio, defined as the ratio of green energy produced divided by the amount of fossil energy consumed, is projected to be 3.11 to 12.32 for the indirect route depending upon the details of implementation. Conventional technology has an energy ratio of 1.34, thus the indirect route will have a significant environmental advantage over today's technology. Energy savings of 7.48 trillion Btu/yr will result when 100 MMgal/yr (neat) of ethanol capacity via the indirect route is placed on-line by the year 2010.

Alexander Maune

2014-06-01

Full Text Available The purpose of this article is to provide an overview, from literature, about how competitive intelligence can be an enabler towards a firm’s competitiveness. This overview is done under the background of intense global competition that firms are currently experiencing. This paper used a qualitative content analysis as a data collection methodology on all identified journal articles on competitive intelligence and firm competitiveness. To identify relevant literature, academic databases and search engines were used. Moreover, a review of references in related studies led to more relevant sources, the references of which were further reviewed and analysed. To ensure reliability and trustworthiness, peer-reviewed journal articles and triangulation were used. The paper found that competitive intelligence is an important enabler of firm competitiveness. The findings from this paper will assist business managers to understand and improve their outlook of competitive intelligence as an enabler of firm competitiveness and will be of great academic value.

Rubinstein, F.; Morse, O.; Clark, T.

1993-01-01

The performance of a retrofitted indirect lighting system was compared to the performance of a typical de-lamped direct lighting system in a partitioned office space. Power, illuminance and luminance measurements were made for the de-lamped direct lighting system and after installation of the indirect lighting system with various lamp and ballast combinations. Using the same lamps and ballasts, average workplace illuminance was slightly higher with indirect lighting than with direct lighting. With indirect lighting, workplace lumen efficacy was 4.5% lower due to the higher power draw of the lamps in the more open and cooler indirect fixtures. Indirect lighting with 36 watt T-8 lamps and electronic ballasts achieved an initial average workplace illuminance of 45 foot-candles in the partitioned office space at only 1.1 w/ft 2

Full Text Available The article is devoted to the problems of using fiscal levers to regulate the national economy competitiveness. What kind of tax levers should be used in order to increase the competitiveness of the national economy is justified. Taxes are the main source of fiscal revenue of the country, which depends on the inherent principles of optimizing the tax system, determined Ukraine's withdrawal from the crisis and raising the country's competitiveness. It is proposed differentiation in income tax rates, depending on whether the company is engaged in innovation and investment activity or not. Changing the rate of value added tax in a downward will reduce the revenue of the country. For enterprises that are not exporting products to decrease the amount of working capital for a certain period Fiscal policy that promotes the removal of the country's financial and economic crisis and the increasing competitiveness of the state, should be challenging. In order to implement incentive effects of taxes set forth in the tax code, we propose a linear programming model of the budget (revenue and expenditure . Building the economic and mathematical optimization model with possible actions challenging the tax factors of individual taxes and the possibilities of using the proceeds of certain taxes on certain items of expenditure budget.

Full Text Available With accelerating urbanization, urban competitiveness has become a worldwide academic focus. Previous studies always focused on economic factors but ignored social elements when measuring urban competitiveness. In this paper, a city was considered as a whole containing different units such as departments, individuals and economic activities, which interact with each other and affect its economic operation. Moreover, a city’s development was compared to an object’s movement, and the components were compared to different forces acting upon the object. With the analysis of the principle of object movement, this study has established a more scientific evaluation index system that involves 4 subsystems, 12 elements and 58 indexes. By using the TOPSIS method, the study has worked out the urban competitiveness of 141 cities from 28 Chinese urban clusters in 2009. According to the calculation results, these cities were divided into four levels: A, B, C, D. Furthermore, in order to analyze the competitiveness of cities and urban clusters, cities and urban clusters have been divided into four groups according to their distributive characteristics: the southeast, the northeast and Bohai Rim, the central region and the west. Suggestions and recommendations for each group are provided based on careful analysis.

Homogeneous non-competitive bioaffinity assay based on fluorescence resonance energy transfer

Kokko, Tiina; Kokko, Leena; Soukka, Tero; Loevgren, Timo

2007-01-01

A homogeneous non-competitive assay principle for measurement of small analytes based on quenching of fluorescence is described. Fluorescence resonance energy transfer (FRET) occurs between the donor, intrinsically fluorescent europium(III)-chelate conjugated to streptavidin, and the acceptor, quencher dye conjugated to biotin derivative when the biotin-quencher is bound to Eu-streptavidin. Fluorescence can be measured only from those streptavidins that are bound to biotin of the sample, while the fluorescence of the streptavidins that are not occupied by biotin are quenched by quencher-biotin conjugates. The quenching efficiencies of the non-fluorescent quencher dyes were over 95% and one dye molecule was able to quench the fluorescence of more than one europium(III)-chelate. This, however, together with the quadrovalent nature of streptavidin limited the measurable range of the assay to 0.2-2 nmol L -1 . In this study we demonstrated that FRET could be used to design a non-competitive homogeneous assay for a small analyte resulting in equal performance with competitive heterogeneous assay

Ballistic fractures: indirect fracture to bone.

Science.gov (United States)

Dougherty, Paul J; Sherman, Don; Dau, Nathan; Bir, Cynthia

2011-11-01

Two mechanisms of injury, the temporary cavity and the sonic wave, have been proposed to produce indirect fractures as a projectile passes nearby in tissue. The purpose of this study is to evaluate the temporal relationship of pressure waves using strain gauge technology and high-speed video to elucidate whether the sonic wave, the temporary cavity, or both are responsible for the formation of indirect fractures. Twenty-eight fresh frozen cadaveric diaphyseal tibia (2) and femurs (26) were implanted into ordnance gelatin blocks. Shots were fired using 9- and 5.56-mm bullets traversing through the gelatin only, passing close to the edge of the bone, but not touching, to produce an indirect fracture. High-speed video of the impact event was collected at 20,000 frames/s. Acquisition of the strain data were synchronized with the video at 20,000 Hz. The exact time of fracture was determined by analyzing and comparing the strain gauge output and video. Twenty-eight shots were fired, 2 with 9-mm bullets and 26 with 5.56-mm bullets. Eight indirect fractures that occurred were of a simple (oblique or wedge) pattern. Comparison of the average distance of the projectile from the bone was 9.68 mm (range, 3-20 mm) for fractured specimens and 15.15 mm (range, 7-28 mm) for nonfractured specimens (Student's t test, p = 0.036). In this study, indirect fractures were produced after passage of the projectile. Thus, the temporary cavity, not the sonic wave, was responsible for the indirect fractures.

Indirect effects in dual radiation action

International Nuclear Information System (INIS)

Zaider, M.; Rossi, H.H.

1988-01-01

The basic aim in this paper is to establish the link between indirect effects of radiation action and the spatial distribution of radicals at the time of energy deposition as well as throughout subsequent diffusion and interaction. The fact that radicals diffuse for a finite distance before damaging a biomolecule has dramatic effects on their subsequent probability to result in lesions. Thus at very low DMSO concentrations, where p = 0.5, one expects - all other things being equal - some 75% of the lesions to result from indirect or semidirect lesions. The number calculated here is lower (15%), a direct result of the fact that such lesions involve proximity functions modulated by diffusion. At higher DMSO concentrations this percentage becomes progressively smaller, as expected. It appears thus that for low-LET radiation, the relative amount of indirect damage in single tracks (also termed intratrack or single events) action is very small. By contrast, intertrack (or two-event) contributions will have the ratio between direct and (indirect + semidirect) contributions given by p 2 /(1-p 2 ). The reason for this is that sublesions from different tracks are uniformly distributed throughout the cell nucleus; their probability of interaction should not depend on any previous diffusional processes. For the example given above (p = 0.5) they do expect 65% of intertrack (two-hit) lesions to have resulted from indirect or semidirect mechanisms. This contrast between the almost exclusively direct character of intratrack lesions and the dominant role of indirect action in intertrack lesions produced by low-LET radiation is an important conclusion of this study

Indirect estimators in US federal programs

CERN Document Server

1996-01-01

In 1991, a subcommittee of the Federal Committee on Statistical Methodology met to document the use of indirect estimators - that is, estimators which use data drawn from a domain or time different from the domain or time for which an estimate is required. This volume comprises the eight reports which describe the use of indirect estimators and they are based on case studies from a variety of federal programs. As a result, many researchers will find this book provides a valuable survey of how indirect estimators are used in practice and which addresses some of the pitfalls of these methods.

TOXOCARIASIS: SEROLOGICAL DIAGNOSIS BY INDIRECT ANTIBODY COMPETITION ELISA Diagnóstico sorológico da toxocaríase através do método de ELISA indireto de competição

Directory of Open Access Journals (Sweden)

1999-03-01

Full Text Available Toxocariasis is caused by infection of man by Toxocara canis and Toxocara cati larvae, the common roundworm of dogs and cats. Because larvae are difficult to detect in tissues, diagnosis is mostly based on serology. Non specific reactions are observed mainly due to cross-reactivity with Ascaris sp antigens. This investigation aimed at developing and evaluating an indirect antibody competition ELISA (IACE employing a specific rabbit IgG anti-Toxocara canis excretory-secretory antigens as the competition antibody, in order to improve indirect ELISA specificity performed for toxocariasis diagnosis. For that, the rabbit IgG was previously absorbed by Ascaris suum adult antigens. Sensitivity and specificity of IACE were first evaluated in 28 serum samples of mice experimentally infected with T. canis embryonated eggs. Adopting cut-off value established in this population before infection, sensitivity and specificity were 100% after 20 days post-inoculation. For human population IACE was evaluated using sera from 440 patients with clinical signs of toxocariasis and the cut-off value was established with 60 serum samples from apparently healthy individuals. Using as reference test the indirect ELISA performed by Adolfo Lutz Institute, sensitivity was 60.2%, specificity was 98% and concordance was 77.3%. Repeatability of IACE was evaluated by the inter-reactions variation coefficient (2.4%.A toxocaríase, uma emergente zoonose, é uma síndrome clínica decorrente da infecção humana por larvas de Toxocara canis e Toxocara cati, parasitas intestinais de cães e gatos, respectivamente.

Beyond compliance using environmental, health and safety management information systems (EMISs) to provide quantified competitive advantages

Energy Technology Data Exchange (ETDEWEB)

Schroeder, J.V.; Mayer, G.

1999-07-01

In the last 20 years, federal, state and local regulations have provided regulatory incentives for industry to better manage environmental, health and safety (EHS) practices. In order for voluntary EHS management practices to move beyond compliance and continue improving, specific, quantifiable benefits must result. That is, companies must achieve some competitive advantage from implementing EHS improvements that are considered voluntary. Recently, many private companies and public agencies have been giving significant consideration toward the implementation of an EHS management information system (EMIS). Currently considered voluntary, the automation of EHS data collection, storage, retrieval and reporting is subject to the same benefit expectations that other EHS improvements are subject to. The benefits resulting from an EMIS typically result from a reduction in either direct or indirect costs. Direct costs, consisting primarily of labor hours, permit fees, disposal costs, etc., are definable and easily to quantify. Indirect costs, which are comprised of reduced risks and liabilities, are less easily quantifiable. In fact, many have abandoned hope of ever quantifying expected benefits from indirect costs, and simply lump all indirect benefits into a qualitative, catch-all category called intangible benefits. However, by statistically analyzing individual risk events over an expected project life, anticipated benefits can be objectively and accurately quantified. Through the use of a case study, this paper will describe the process of quantifying direct and indirect benefits resulting from the implementation of an EMIS. The paper will describe the application of a statistical model to estimate indirect benefits and will demonstrate how the results of the benefit quantification can be used to make sound, business based decisions based on a required rate of return/return on investment.

Indirect reciprocity with optional interactions.

Science.gov (United States)

Ghang, Whan; Nowak, Martin A

2015-01-21

Indirect reciprocity is a mechanism for the evolution of cooperation that is relevant for prosocial behavior among humans. Indirect reciprocity means that my behavior towards you also depends on what you have done to others. Indirect reciprocity is associated with the evolution of social intelligence and human language. Most approaches to indirect reciprocity assume obligatory interactions, but here we explore optional interactions. In any one round a game between two players is offered. A cooperator accepts a game unless the reputation of the other player indicates a defector. For a game to take place, both players must accept. In a game between a cooperator and a defector, the reputation of the defector is revealed to all players with probability Q. After a sufficiently large number of rounds the identity of all defectors is known and cooperators are no longer exploited. The crucial condition for evolution of cooperation can be written as hQB>1, where h is the average number of rounds per person and B=(b/c)-1 specifies the benefit-to-cost ratio. We analyze both stochastic and deterministic evolutionary game dynamics. We study two extensions that deal with uncertainty: hesitation and malicious gossip. Copyright © 2014 Elsevier Ltd.

The National Clinical Skills Competition has been held in China for 5 consecutive years since 2010 to promote undergraduate education reform and improve the teaching quality. The effects of the simulation-based competition will be analyzed in this study. Participation in the competitions and the compilation of the questions used in the competition finals are summarized, and the influence and guidance quality are further analyzed. Through the nationwide distribution of questionnaires in medical colleges, the effects of the simulation-based competition on promoting undergraduate medical education reform were evaluated. The results show that approximately 450 students from more than 110 colleges (accounting for 81% of colleges providing undergraduate clinical medical education in China) participated in the competition each year. The knowledge, skills, and attitudes were comprehensively evaluated by simulation-based assessment. Eight hundred and eighty copies of the questionnaires were distributed to 110 participating medical schools in 2015. In total, 752 valid responses were received across 95 schools. The majority of the interviewees agreed or strongly agreed that competition promoted the adoption of advanced educational principles (76.8%), updated the curriculum model and instructional methods (79.8%), strengthened faculty development (84.0%), improved educational resources (82.1%), and benefited all students (53.4%). The National Clinical Skills Competition is widely accepted in China. It has effectively promoted the reform and development of undergraduate medical education in China.

This editorial opens the second special section on physics competitions in European Journal of Physics. In the first section last year, we asked for feedback on the idea of such a section and on the content of the articles. We received no answer whatsoever, which can be interpreted in two ways: the section is not interesting enough to raise motivation for feedback, or the reader is satisfied. Having no indication which scenario is the correct one, we are optimistic and favour the second. The section at hand contains three articles. Again, as last year, the organizer of the annual Olympiad reports on tasks and outcomes of this competition. The Olympiad took place in Merida, Mexico, and was by far the largest event with 316 contestants from 68 countries. Again, the predominance of Asian/Chinese students was manifest, showing how serious the training is taken by both their authorities and students. Unfortunately, the winners of the last International Young Physicists' Tournament (IYPT), the team from Korea, did not accept the offer to report on their prize-winning contribution. We are thankful that two students from Austria, who achieved second place with their team, took over and reported on the task which they presented in the finals of the competition. It connects the fields of sport and physics and explains a special move in skateboarding. The third contribution introduces a different competition, 'International Conference of Young Scientists'. On one hand, as in the Olympiad, it addresses individuals, not teams. On the other, as in the IYPT, students have several months to prepare and also the quality of the presentation is an important element of the judgment. In fact, this competition comes closer to real scientific research compared to the other events. Finally and again, we hope that this section will serve several purposes: To show the competitions as a very important tool in the support of gifted students. To raise awareness amongst university teachers, and

Indirect Comorbidity in Childhood and Adolescence

Directory of Open Access Journals (Sweden)

William eCopeland

2013-11-01

Full Text Available Objective: Comorbidity between psychiatric disorders is common, but pairwise associations between two disorders may be explained by the presence of other diagnoses that are associated with both disorders or indirect comorbidity. Method: Comorbidities of common childhood psychiatric disorders were tested in three community samples of children ages 6 to 17 (8931 observations of 2965 subjects. Psychiatric disorder status in all three samples was assessed with the Child and Adolescent Psychiatric Assessment. Indirect comorbidity was defined as A-B associations that decreased from significance to nonsignificance after adjusting for other disorders. Results: All tested childhood psychiatric disorders were positively associated in bivariate analyses. After adjusting for comorbidities, many ssociations involving a behavioral disorder and an emotional disorder were attenuated suggesting indirect comorbidity. Generalized anxiety and depressive disorders displayed a very high level of overlap (adjusted OR=37.9. All analyses were rerun with depressive disorders grouped with generalized anxiety disorder in a single distress disorders category. In these revised models, all associations between and emotional disorder and a behavior disorder met our criteria for indirect comorbidity except for the association of oppositional defiant disorder with distress disorders (OR=11.3. Follow-up analyses suggested that the indirect associations were primarily accounted for by oppositional defiant disorder and the distress disorder category. There was little evidence of either sex differences or differences by developmental period Conclusions: After accounting for the overlap between depressive disorders with generalized anxiety disorder, direct comorbidity between emotional and behavioral disorders was uncommon. When there was evidence of indirect comorbidity, ODD and distress disorders were the key intermediary diagnoses accounting for the apparent associations.

The Politics of Global Indicators in Designing, Promoting and Legitimating the Competition State

Directory of Open Access Journals (Sweden)

Diego Giannone

2017-10-01

Full Text Available Global indicators of state's performance have grown exponentially over the last three dec-ades. Issues such as economic freedom, competitiveness, property rights, business environment, credit-worthiness, democracy, governance, transparency and media freedom have become central topics of several global benchmarks focused on the evaluation of the state. The objective of this paper is to analyze the reasons behind this phenomenon, investigating the role of those global indicators in world politics and the shaping of an "ideal state". In the first section, the study emphasizes that the global diffusion of rankings and ratings is primarily linked to the rise of neoliberalism. Drawing on Michel Foucault's work on governmentality, global indicators are conceived as specific apparatuses of neoliberal rationality that help to conform states' polities and policies to the twin neoliberal principles of competitiveness and en-trepreneurship. The second section describes the often contradictory construction of the neoliberal com-petition state. Then the study analyzes how the neoliberal state is forged by global indicators. Specifically, the paper focuses on the Global Competitiveness Index by the World Economic Forum. The article ends with some concluding remarks on the power of global indicators and some suggestion for future research.

2016-08-01

A job shop has an arrangement where similar machines (Direct consumables) are grouped together and use indirect consumables to produce a product. The indirect consumables include hack saw blades, emery paper, painting brush etc. The job shop is serving various orders at a particular time for the optimal operation of job shop. Forecasting is required to predict the demand of direct and indirect consumables in a job shop. Forecasting is also needed to manage lead time, optimize inventory cost and stock outs. The objective of this research is to obtain the forecast for indirect consumables. The paper shows how job shop can manage their indirect consumables more accurately by establishing a new technique of forecasting. This results in profitable use of job shop by multiple users.

Interaction of nitroaromatic radiosensitizers with irradiated polyadenylic acid as measured by an indirect immunochemical assay with specificity for the 8,5'-cycloadenosine moiety

Energy Technology Data Exchange (ETDEWEB)

Fuciarelli, A F; Mele, F G; Raleigh, J A

1987-04-01

The relative reactivity of a series of nitroaromatic radiosensitizers toward the C(5') radical intermediate leading to 8,5'-cycloadenosine formation in deoxygenated solutions of irradiated polyadenylic acid (poly A) was assessed using standard competition kinetic analysis. Formation of 8,5'-cycloadenosine was assayed by an indirect, competitive, enzyme-linked immunosorbent assay (ELISA) described in an earlier report. In the absence of oxygen, the nitroaromatics inhibit 8,5'-cyclonucleoside formation in a way which generally increases with radiosensitizer electron affinity. Although hydroxyl radical scavenging by the nitroaromatics may account for a relatively small decrease in 8,5'cyclonucleoside formation, the data suggest that oxidation of the C(5') radical intermediate is the more plausible explanation for the decreased yield of the 8,5'-cyclonucleoside with increasing nitroaromatic electron affinity.

Bateman's principle is reversed in a cooperatively breeding bird.

Apakupakul, Kathleen; Rubenstein, Dustin R

2015-04-01

Bateman's principle is not only used to explain sex differences in mating behaviour, but also to determine which sex has the greater opportunity for sexual selection. It predicts that the relationship between the number of mates and the number of offspring produced should be stronger for males than for females. Yet, it is unclear whether Bateman's principle holds in cooperatively breeding systems where the strength of selection on traits used in intrasexual competition is high in both sexes. We tested Bateman's principle in the cooperatively breeding superb starling (Lamprotornis superbus), finding that only females showed a significant, positive Bateman gradient. We also found that the opportunity for selection was on average higher in females, but that its strength and direction oscillated through time. These data are consistent with the hypothesis that sexual selection underlies the female trait elaboration observed in superb starlings and other cooperative breeders. Even though the Bateman gradient was steeper for females than for males, the year-to-year oscillation in the strength and direction of the opportunity for selection likely explains why cooperative breeders do not exhibit sexual role reversal. Thus, Bateman's principle may not hold in cooperative breeders where both sexes appear to be under mutually strong sexual selection. © 2015 The Author(s) Published by the Royal Society.

Competitive protein binding assay

International Nuclear Information System (INIS)

Kaneko, Toshio; Oka, Hiroshi

1975-01-01

The measurement of cyclic GMP (cGMP) by competitive protein binding assay was described and discussed. The principle of binding assay was represented briefly. Procedures of our method by binding protein consisted of preparation of cGMP binding protein, selection of 3 H-cyclic GMP on market, and measurement procedures. In our method, binding protein was isolated from the chrysalis of silk worm. This method was discussed from the points of incubation medium, specificity of binding protein, the separation of bound cGMP from free cGMP, and treatment of tissue from which cGMP was extracted. cGMP existing in the tissue was only one tenth or one scores of cGMP, and in addition, cGMP competed with cGMP in binding with binding protein. Therefore, Murad's technique was applied to the isolation of cGMP. This method provided the measurement with sufficient accuracy; the contamination by cAMP was within several per cent. (Kanao, N.)

Unstable gravitino dark matter prospects for indirect and direct detection

International Nuclear Information System (INIS)

Grefe, Michael

2011-11-01

We confront the signals expected from unstable gravitino dark matter with observations of indirect dark matter detection experiments in all possible cosmic-ray channels. For this purpose we calculate in detail the gravitino decay widths in theories with bilinear violation of R parity, particularly focusing on decay channels with three particles in the final state. Based on these calculations we predict the fluxes of gamma rays, charged cosmic rays and neutrinos expected from decays of gravitino dark matter. Although the predicted spectra could in principal explain the anomalies observed in the cosmic ray positron and electron fluxes as measured by PAMELA and Fermi LAT, we find that this possibility is ruled out by strong constraints from gamma-ray and antiproton observations. Therefore, we employ current data of indirect detection experiments to place strong constraints on the gravitino lifetime and the strength of R-parity violation. In addition, we discuss the prospects of forthcoming searches for a gravitino signal in the spectrum of cosmic-ray antideuterons, finding that they are in particular sensitive to rather low gravitino masses. Finally, we discuss in detail the prospects for detecting a neutrino signal from gravitino dark matter decays, finding that the sensitivity of neutrino telescopes like IceCube is competitive to observations in other cosmic ray channels, especially for rather heavy gravitinos. Moreover, we discuss the prospects for a direct detection of gravitino dark matter via R-parity violating inelastic scatterings off nucleons. We find that, although the scattering cross section is considerably enhanced compared to the case of elastic gravitino scattering, the expected signal is many orders of magnitude too small in order to hope for a detection in underground detectors.

Therefore, we employ current data of indirect detection experiments to place strong constraints on the gravitino lifetime and the strength of R-parity violation. In addition, we discuss the prospects of forthcoming searches for a gravitino signal in the spectrum of cosmic-ray antideuterons, finding that they are in particular sensitive to rather low gravitino masses. Finally, we discuss in detail the prospects for detecting a neutrino signal from gravitino dark matter decays, finding that the sensitivity of neutrino telescopes like IceCube is competitive to observations in other cosmic ray channels, especially for rather heavy gravitinos. Moreover, we discuss the prospects for a direct detection of gravitino dark matter via R-parity violating inelastic scatterings off nucleons. We find that, although the scattering cross section is considerably enhanced compared to the case of elastic gravitino scattering, the expected signal is many orders of magnitude too small in order to hope for a detection in underground detectors.

2016-12-01

Full Text Available Tourist destinations are now faced with increased competition at the market and holders of tourist policy and offers have realized that understanding the factors that contribute to a better positioning in the market place, and therefore the competitiveness, is of crucial importance for further development. The aim of this paper is to determine how much Vojvodina is competitive as a rural tourism destination, and to assess the current state of all the factors that affect/could affect the competitiveness of rural tourism destinations in Vojvodina Province (Northern Serbia. The total of 136 tourism experts were interviewed, and we concluded that the key resources and attraction of rural areas in Vojvodina are rated better than the macro and industry-related factors. This suggests that a rural development strategy should have a special bond with resources and attractions of the destination, that priority should be given to maintaining all aspects of safety and security, continuous improvement of services, diversity of culinary products, as well as the application of the principles of sustainability in environmental management. The work of national and provincial institutions should have the aim to ensure that the destination has a clear idea of where it is going and what it takes to become successful in the long term.

Competition in Japan

This article examines competition in Japan and its link to postwar economic prosperity. While Japan's industrial structure and competition policy seem to indicate that competition in Japan has been less intense, the empirical evidence does not support this conclusion. The sectors in which competition was restricted prove to be those where Japan was not internationally successful. In the internationally successful sectors, internal competition in Japan was invariably fierce. While the level of...

Competitive bidding in Medicare: who benefits from competition?

2012-09-01

To conduct the first empirical study of competitive bidding in Medicare. We analyzed 2006-2010 Medicare Advantage data from the Centers for Medicare and Medicaid Services using longitudinal models adjusted for market and plan characteristics. A $1 increase in Medicare's payment to health maintenance organization (HMO) plans led to a $0.49 (P service plans included, higher Medicare payments increased bids less ($0.33 per dollar), suggesting more competition among these latter plans. As a market-based alternative to cost control through administrative pricing, competitive bidding relies on private insurance plans proposing prices they are willing to accept for insuring a beneficiary. However, competition is imperfect in the Medicare bidding market. As much as half of every dollar in increased plan payment went to higher bids rather than to beneficiaries. While having more insurers in a market lowered bids, the design of any bidding system for Medicare should recognize this shortcoming of competition.

Data-Foraging-Oriented Reconnaissance Based on Bio-Inspired Indirect Communication for Aerial Vehicles

Directory of Open Access Journals (Sweden)

Josué Castañeda Cisneros

2017-07-01

Full Text Available In recent years, aerial vehicles have allowed exploring scenarios with harsh conditions. These can conduct reconnaissance tasks in areas that change periodically and have a high spatial and temporal resolution. The objective of a reconnaissance task is to survey an area and retrieve strategic information. The aerial vehicles, however, have inherent constraints in terms of energy and transmission range due to their mobility. Despite these constraints, the Data Foraging problem requires the aerial vehicles to exchange information about profitable data sources. In Data Foraging, establishing a single path is not viable because of dynamic conditions of the environment. Thus, reconnaissance must be focused on periodically searching profitable environmental data sources, as some animals perform foraging. In this work, a data-foraging-oriented reconnaissance algorithm based on bio-inspired indirect communication for aerial vehicles is presented. The approach establishes several paths that overlap to identify valuable data sources. Inspired by the stigmergy principle, the aerial vehicles indirectly communicate through artificial pheromones. The aerial vehicles traverse the environment using a heuristic algorithm that uses the artificial pheromones as feedback. The solution is formally defined and mathematically evaluated. In addition, we show the viability of the algorithm by simulations which have been tested through various statistical hypothesis.

Direct and indirect punishment among strangers in the field.

Balafoutas, Loukas; Nikiforakis, Nikos; Rockenbach, Bettina

2014-11-11

Many interactions in modern human societies are among strangers. Explaining cooperation in such interactions is challenging. The two most prominent explanations critically depend on individuals' willingness to punish defectors: In models of direct punishment, individuals punish antisocial behavior at a personal cost, whereas in models of indirect reciprocity, they punish indirectly by withholding rewards. We investigate these competing explanations in a field experiment with real-life interactions among strangers. We find clear evidence of both direct and indirect punishment. Direct punishment is not rewarded by strangers and, in line with models of indirect reciprocity, is crowded out by indirect punishment opportunities. The existence of direct and indirect punishment in daily life indicates the importance of both means for understanding the evolution of cooperation.

Description of a nanobody-based competitive immunoassay to detect tsetse fly exposure.

2015-02-01

Full Text Available Tsetse flies are the main vectors of human and animal African trypanosomes. The Tsal proteins in tsetse fly saliva were previously identified as suitable biomarkers of bite exposure. A new competitive assay was conceived based on nanobody (Nb technology to ameliorate the detection of anti-Tsal antibodies in mammalian hosts.A camelid-derived Nb library was generated against the Glossina morsitans morsitans sialome and exploited to select Tsal specific Nbs. One of the three identified Nb families (family III, TsalNb-05 and TsalNb-11 was found suitable for anti-Tsal antibody detection in a competitive ELISA format. The competitive ELISA was able to detect exposure to a broad range of tsetse species (G. morsitans morsitans, G. pallidipes, G. palpalis gambiensis and G. fuscipes and did not cross-react with the other hematophagous insects (Stomoxys calcitrans and Tabanus yao. Using a collection of plasmas from tsetse-exposed pigs, the new test characteristics were compared with those of the previously described G. m. moristans and rTsal1 indirect ELISAs, revealing equally good specificities (> 95% and positive predictive values (> 98% but higher negative predictive values and hence increased sensitivity (> 95% and accuracy (> 95%.We have developed a highly accurate Nb-based competitive immunoassay to detect specific anti-Tsal antibodies induced by various tsetse fly species in a range of hosts. We propose that this competitive assay provides a simple serological indicator of tsetse fly presence without the requirement of test adaptation to the vertebrate host species. In addition, the use of monoclonal Nbs for antibody detection is innovative and could be applied to other tsetse fly salivary biomarkers in order to achieve a multi-target immunoprofiling of hosts. In addition, this approach could be broadened to other pathogenic organisms for which accurate serological diagnosis remains a bottleneck.

The role of socio-technical principles in leveraging meaningful benefits from IT investments.

Doherty, Neil F

2014-03-01

In recent years there has been a great deal of academic and practitioner interest in the role of 'benefits realisation management' [BRM] approaches, as a means of proactively leveraging value from IT investments. This growing body of work owes a very considerable, but as yet unacknowledged, debt to the work of Ken Eason, and other early socio-technical theorists. Consequently, the aim of this paper is to demonstrate, using the literature, how many of the principles, practices and techniques of BRM have evolved either directly or indirectly from socio-technical approaches to systems design. In so doing, this article makes a further important contribution to the literature by explicitly identifying the underlying principles and key practices of benefits realisation management.

Martinez, D A; Smalyuk, V A; Kane, J O; Casner, A; Liberatore, S; Masse, L P

2015-05-29

We investigate on the National Ignition Facility the ablative Rayleigh-Taylor instability in the transition from weakly nonlinear to highly nonlinear regimes. A planar plastic package with preimposed two-dimensional broadband modulations is accelerated for up to 12 ns by the x-ray drive of a gas-filled Au radiation cavity with a radiative temperature plateau at 175 eV. This extended tailored drive allows a distance traveled in excess of 1 mm for a 130  μm thick foil. Measurements of the modulation optical density performed by x-ray radiography show that a bubble-merger regime for the Rayleigh-Taylor instability at an ablation front is achieved for the first time in indirect drive. The mutimode modulation amplitudes are in the nonlinear regime, grow beyond the Haan multimode saturation level, evolve toward the longer wavelengths, and show insensitivity to the initial conditions.

Modelling the competition of planktonic and sessile aerobic heterotrophs for complementary nutrients in biofilm reactor.

Lu, T; Saikaly, P E; Oerther, D B

2007-01-01

A comprehensive, simplified microbial biofilm model was developed to evaluate the impact of bioreactor operating parameters on changes in microbial population abundance. Biofilm simulations were conducted using three special cases: fully penetrated, internal mass transfer resistance and external mass transfer resistance. The results of model simulations showed that for certain operating conditions, competition for growth limiting nutrients generated oscillations in the abundance of planktonic and sessile microbial populations. These oscillations resulted in the violation of the competitive exclusion principle where the number of microbial populations was greater than the number of growth limiting nutrients. However, the operating conditions which impacted microbial community diversity were different for the three special cases. Comparing the results of model simulations for dispersed-growth, biofilms and bioflocs showed that oscillations and microbial community diversity were a function of competition as well as other key features of the ecosystem. The significance of the current study is that it is the first to examine competition as a mechanism for controlling microbial community diversity in biofilm reactors.

Full Text Available With globalization, the rapid development of information technologies and the rapid changes in the economic structure, the country’s borders at a time increasingly depreciate and the importance of city competitiveness reveals. Although it is an ongoing debate around the world whether cities compete with each other, city competitiveness is a new form of competitiveness. Cities compete with each other to increase their competitiveness. City competitiveness is defined as having better values compared to other cities. In this study, a new form of competitiveness called city competitiveness is examined.

Competition with and without priority control: linking rivalry to attention through winner-take-all networks with memory.

Competition is ubiquitous in perception. For example, items in the visual field compete for processing resources, and attention controls their priority (biased competition). The inevitable ambiguity in the interpretation of sensory signals yields another form of competition: distinct perceptual interpretations compete for access to awareness. Rivalry, where two equally likely percepts compete for dominance, explicates the latter form of competition. Building upon the similarity between attention and rivalry, we propose to model rivalry by a generic competitive circuit that is widely used in the attention literature-a winner-take-all (WTA) network. Specifically, we show that a network of two coupled WTA circuits replicates three common hallmarks of rivalry: the distribution of dominance durations, their dependence on input strength ("Levelt's propositions"), and the effects of stimulus removal (blanking). This model introduces a form of memory by forming discrete states and explains experimental data better than competitive models of rivalry without memory. This result supports the crucial role of memory in rivalry specifically and in competitive processes in general. Our approach unifies the seemingly distinct phenomena of rivalry, memory, and attention in a single model with competition as the common underlying principle. © 2015 The Authors.

An effective model for fermion dark matter. Indirect detection of supersymmetric dark matter in astronomy with the CELESTE Telescope

International Nuclear Information System (INIS)

Lavalle, Julien

2004-01-01

The purpose of this thesis is to discuss both phenomenological and experimental aspects of Dark Matter, related to its indirect detection with gamma-ray astronomy. In the MSSM framework, neutralinos arise as natural candidates to non-baryonic and Cold Dark Matter, whose gravitational effects manifest in the Universe at different scales. As they are Majorana particles, they may in principle annihilate in high density regions, as the centres of galaxies, and produce gamma rays. Nevertheless, the expected fluxes are basically low compared to experimental sensitivities. After estimating gamma fluxes from M31 and Draco galaxies in the MSSM scheme, we first generalize the MSSM couplings by studying an effective Lagrangian. We show that the only constraint of imposing a relic abundance compatible with recent measurements obviously deplete significantly the gamma ray production, but also that predictions in this effective approach are more optimistic for indirect detection than the MSSM. In a second part, we present the indirect searches for Dark Matter performed with the CELESTE Cherenkov telescope towards the galaxy M31. We propose a statistical method to reconstruct spectra, mandatory to discriminate classical and exotic spectra. The M31 data analysis enables the extraction of an upper limit on the gamma ray flux, which is the first worldwide for a galaxy in the energy range 50-500 GeV, and whose astrophysical interest goes beyond indirect searches for Dark Matter.

Full Text Available Background: The National Clinical Skills Competition has been held in China for 5 consecutive years since 2010 to promote undergraduate education reform and improve the teaching quality. The effects of the simulation-based competition will be analyzed in this study. Methods: Participation in the competitions and the compilation of the questions used in the competition finals are summarized, and the influence and guidance quality are further analyzed. Through the nationwide distribution of questionnaires in medical colleges, the effects of the simulation-based competition on promoting undergraduate medical education reform were evaluated. Results: The results show that approximately 450 students from more than 110 colleges (accounting for 81% of colleges providing undergraduate clinical medical education in China participated in the competition each year. The knowledge, skills, and attitudes were comprehensively evaluated by simulation-based assessment. Eight hundred and eighty copies of the questionnaires were distributed to 110 participating medical schools in 2015. In total, 752 valid responses were received across 95 schools. The majority of the interviewees agreed or strongly agreed that competition promoted the adoption of advanced educational principles (76.8%, updated the curriculum model and instructional methods (79.8%, strengthened faculty development (84.0%, improved educational resources (82.1%, and benefited all students (53.4%. Conclusions: The National Clinical Skills Competition is widely accepted in China. It has effectively promoted the reform and development of undergraduate medical education in China.

INDIRECT COSTS ALLOCATION AND DECISION MAKING IN AGRICULTURAL PRODUCTION

2001-06-01

Full Text Available The paper introduces a research on the changes occurred inside the accounting system of agricultural organisations in the transitional period. Changes of structure and accounting information system being results of privatisation processes were analysed. The introduction of modern methods in the preparation of relevant management information represents one of the preconditions for development of the privatised agricultural organisation during the transition period. Information prepared by the accounting, especially adapted to management requirements, is essential for rational decision making. Modern management system of reporting is fundamental task of management and a precondition for securing competitive production in agricultural industry. For this reason, it is necessary to define areas of responsibility and to enable application of a modern techniques for calculating expenses. The purpose of this paper is to emphasise the specialised use of accounting information by managers and to develop methods of management reporting in agricultural organisations. We propose an emphasis upon the application of modern management accounting techniques rather than financial accounting reporting approach. We support the contention that the need for high-quality management accounting is not debatable and tend to explain how and why accounting information is developed for the individual parts of a business entity, that is for each department or enterprise of an agricultural organisation. The responsibility accounting system should be introduced in agricultural business entities within our conditions, especially in larger organisations, as a measure of securing competitive production. We emphasise the importance of distinguishing between direct and indirect expenses and of using appropriate methods to allocate expenses among departments or enterprises. The research is based on information directly received from the largest agricultural companies in the area of

Context-dependent competition in a model gut bacterial community.

Directory of Open Access Journals (Sweden)

Eric J de Muinck

Full Text Available Understanding the ecological processes that generate complex community structures may provide insight into the establishment and maintenance of a normal microbial community in the human gastrointestinal tract, yet very little is known about how biotic interactions influence community dynamics in this system. Here, we use natural strains of Escherichia coli and a simplified model microbiota to demonstrate that the colonization process on the strain level can be context dependent, in the sense that the outcome of intra-specific competition may be determined by the composition of the background community. These results are consistent with previous models for competition between organisms where one competitor has adapted to low resource environments whereas the other is optimized for rapid reproduction when resources are abundant. The genomic profiles of E. coli strains representing these differing ecological strategies provide clues for deciphering the genetic underpinnings of niche adaptation within a single species. Our findings extend the role of ecological theory in understanding microbial systems and the conceptual toolbox for describing microbial community dynamics. There are few, if any, concrete examples of context-dependent competition on a single trophic level. However, this phenomenon can have potentially dramatic effects on which bacteria will successfully establish and persist in the gastrointestinal system, and the principle should be equally applicable to other microbial ecosystems.

Manifestation of Aerosol Indirect Effects in Arctic Clouds

Lubin, D.; Vogelmann, A. M.

2009-12-01

The first aerosol indirect effect has traditionally been conceived as an enhancement of shortwave cloud reflectance in response to decreased effective droplet size at fixed liquid water path, as cloud nucleating aerosol becomes entrained in the cloud. The high Arctic, with its pervasive low-level stratiform cloud cover and frequent episodes of anthropogenic aerosol (Artic "haze"), has in recent years served as a natural laboratory for research on actual manifestations of aerosol indirect effects. This paper will review the surprising set of developments: (1) the detection of the indirect effect as a source of surface warming, rather than cooling, throughout early spring, (2) a transition to a cooling effect in late spring, corresponding to the beginning of the sea ice melt season, and (3) detection of an indirect effect during summer, outside of the "Arctic haze" season. This paper will also discuss measurements of spectral shortwave irradiance (350-2200 nm) made at Barrow, Alaska, during the U.S. Department of Energy's Indirect and Semi-Direct Aerosol Campaign (ISDAC), which reveal complications in our conception of the indirect effect related to the ice phase in Arctic stratiform clouds.

This study quantified differences in indirect costs due to decreased work productivity between current and former smokers. Former smokers were further categorized by number of years since quitting to assess corresponding differences. Data on employed individuals were obtained from the 2013 US National Health and Wellness Survey (NHWS; N = 75,000). Indirect costs were calculated for current smokers and former smokers from weekly wages based on age and sex. The annual total indirect costs for current smokers were $1327.53, $1560.18, and $1839.87 higher than for those who quit 0 to 4 years, 5 to 10 years, and more than or equal to 11 years prior, respectively. There were no significant differences in mean total indirect costs between the former smoker groups. Current smokers showed significantly higher total annual indirect costs compared with former smokers, independently of the number of years since quitting smoking.

Phase competition by design in R0.5Ba0.5MnO3

Science.gov (United States)

Nowadnick, Elizabeth; He, Jiangang; Fennie, Craig

Phase competition between distinct ground states can arise from interactions on similar energy scales between the spin, charge, lattice, and orbital degrees of freedom. This competition can result in large responses to external perturbations. For example, the colossal magnetoresistance effect in the rare-earth manganites R1-xAxMnO3 arises out of competing ferromagnetic metallic and charge/orbital-ordered antiferromagnetic insulating states. Phase competition between polar and magnetic ground states is a promising strategy to realize polarization (magnetization) control with a magnetic (electric) field, which is major goal in multiferroics research. In this regard, the half-doped A-site ordered manganite Sm0.5Ba0.5MnO3 is of particular interest, because the charge/orbital-ordered antiferromagnetic insulating state in this material is polar. We use a combination of group theoretic methods and first-principles calculations to elucidate the origin of this polar state, and show that epitaxial strain can tune the material to a regime where there is a strong competition between the polar insulating state and the ferromagnetic metallic state. We then explore how to achieve electric and magnetic field control of the order parameters in this system.

Plant species within communities may overlap in pollinators' use and influence visitation patterns of shared pollinators, potentially engaging in indirect interactions (e.g., facilitation or competition). While several studies have explored the mechanisms regulating insect-pollination networks, there is a lack of studies on bird-pollination systems, particularly in species-rich tropical areas. Here, we evaluated if phenotypic similarity, resource availability (floral abundance), evolutionary relatedness and flowering phenology affect the potential for indirect effects via shared pollinators in hummingbird-pollinated plant species within four communities in the Brazilian Atlantic forest. Among the evaluated factors, phenotypic similarity (corolla length and anther height) was the most important variable, while resource availability (floral abundance) had a secondary importance. On the other hand, evolutionary relatedness and flowering phenology were less important, which altogether highlights the relevance of convergent evolution and that the contribution of a plant to the diet of the pollinators of another plant is independent of the level of temporal overlap in flowering in this tropical system. Interestingly, our findings contrast with results from multiple insect-pollinated plant communities, mostly from temperate regions, in which floral abundance was the most important driver, followed by evolutionary relatedness and phenotypic similarity. We propose that these contrasting results are due to high level of specialization inherent to tropical hummingbird-pollination systems. Moreover, our results demonstrated that factors defining linkage rules of plant-hummingbird networks also determinate plant-plant potential indirect effects. Future studies are needed to test if these findings can be generalized to other highly specialized systems. Overall, our results have important implications for the understanding of ecological processes due resource sharing in

Various global competitive rankings measurements have indicated over a number of years the areas in which competitiveness is lacking. Moreover, these rankings have indicated that South Africa has failed to improve its position year on year. The fact that the world is becoming increasingly competitive for South African entities is undisputed. Coupled with a fluctuating exchange rate and the country’s geographical proximity, this poses unique challenges facing South African managers who have to deal with various regulations and legislative matters. In order to create and sustain an effective knowledge economy and to enhance global competitiveness, South Africa however has to put appropriate strategies/measures in place to stimulate, encourage and grow knowledge practices. Competitive Intelligence (CI as a means of making more sense of the competitive business environment and to identify opportunities and risks in time to act upon can be effectively used as a means to enhance competitiveness. Valuable lessons from successful CI practices in the business sector and government can be learnt from elsewhere in the world. CI should be investigated and adapted for South Africa’s business environment. It is therefore the aim of this article to first attempt to describe the role of CI in enhancing competitiveness, specifically in South Africa and secondly, to stimulate thought on how to secure momentum in enhancing CI as an academic field by developing relevant CI courses as well as demonstrating the value of CI to companies in South Africa through research and collaboration between academics and the private and public sectors.

A sensitive and selective indirect determination of iodide by inductively coupled plasma emission spectrometry (ICP-AES) based on the principle of tandem on-line continuous separations as an alternative means of introducing samples into plasmas is proposed. Iodide is continuously extracted as an ion-pair into xylene by mixing the sample with Hg(II) and dipyridil solutions. The organic phase (containing the analyte in [Hg(Dipy) 2 ]I 2 form) is on-line continuously mixed with NaBH 4 (in DMF) and acetic acid solutions. Mercury vapour continuously generated from this organic phase is separated in a classical U-type gas-liquid separation device. The system has been optimized for the continuous extraction of KI, for the direct generation of cold mercury vapour from xylene and for the final ICP-AES determination of mercury. The optimised method has been applied to the determination of iodide (detection limit 20 ng/ml of iodide) in table salt and in synthetic samples. Very good agreement between found and certified results was observed. The usefulness and convenience of such alternative sample chemical pretreatment/presentation to the ICP is thus demonstrated for indirect determinations to be carried out by atomic spectroscopy methods.

Full Text Available We present results from first principle, local density approximation (LDA calculations of electronic, transport, and bulk properties of iron pyrite (FeS2. Our non-relativistic computations employed the Ceperley and Alder LDA potential and the linear combination of atomic orbitals (LCAO formalism. The implementation of the LCAO formalism followed the Bagayoko, Zhao, and Williams (BZW method, as enhanced by Ekuma and Franklin (BZW-EF. We discuss the electronic energy bands, total and partial densities of states, electron effective masses, and the bulk modulus. Our calculated indirect band gap of 0.959 eV (0.96, using an experimental lattice constant of 5.4166 Å, at room temperature, is in agreement with the measured indirect values, for bulk samples, ranging from 0.84 eV to 1.03 ± 0.05 eV. Our calculated bulk modulus of 147 GPa is practically in agreement with the experimental value of 145 GPa. The calculated, partial densities of states reproduced the splitting of the Fe d bands to constitute the dominant upper most valence and lower most conduction bands, separated by the generally accepted, indirect, experimental band gap of 0.95 eV.

Opposing effects of floral visitors and soil conditions on the determinants of competitive outcomes maintain species diversity in heterogeneous landscapes.

Lanuza, Jose B; Bartomeus, Ignasi; Godoy, Oscar

2018-06-01

Theory argues that both soil conditions and aboveground trophic interactions have equivalent potential to limit or promote plant diversity. However, it remains unexplored how they jointly modify the niche differences stabilising species coexistence and the average fitness differences driving competitive dominance. We conducted a field study in Mediterranean annual grasslands to parameterise population models of six competing plant species. Spatially explicit floral visitor assemblages and soil salinity variation were characterised for each species. Both floral visitors and soil salinity modified species population dynamics via direct changes in seed production and indirect changes in competitive responses. Although the magnitude and sign of these changes were species-specific, floral visitors promoted coexistence at neighbourhood scales, while soil salinity did so over larger scales by changing the superior competitors' identity. Our results show how below and aboveground interactions maintain diversity in heterogeneous landscapes through their opposing effects on the determinants of competitive outcomes. © 2018 John Wiley & Sons Ltd/CNRS.

Full Text Available The article is aimed at defining the conceptual-strategic principles of ensuring the international competitiveness of tourism enterprise. As result of research the essence and value of management of competitiveness of tourism enterprise in the conditions of globalization were considered. Factors of formation of competitive advantages, and also the reasons determining competitiveness of a tourism product have been determined. The main aspects of formation of quality of services provision have been identified. On the basis of the carried out research, the concept of integrated marketing communications has been formed, which is a combination of traditional ways of communication activity with the only synchronized communication, oriented towards establishing the multichannel relationships with different target audiences, with choosing an own marketing model for each audience. Application of the given concept would allow to optimally choose means of communication and to provide more effective realization of a tourism product at the international market of tourism services that will promote companies’ overgrowing their local status and gaining their self-importance on a global scale.

Competitive release and outbreaks of non-target pests associated with transgenic Bt cotton.

Science.gov (United States)

Zeilinger, Adam R; Olson, Dawn M; Andow, David A

2016-06-01

The adoption of transgenic Bt cotton has, in some cases, led to environmental and economic benefits through reduced insecticide use. However, the distribution of these benefits and associated risks among cotton growers and cotton-growing regions has been uneven due in part to outbreaks of non-target or secondary pests, thereby requiring the continued use of synthetic insecticides. In the southeastern USA, Bt cotton adoption has resulted in increased abundance of and damage from stink bug pests, Euschistus servus and Nezara viridula (Heteroptera: Pentatomidae). While the impact of increased stink bug abundance has been well-documented, the causes have remained unclear. We hypothesize that release from competition with Bt-susceptible target pests may drive stink bug outbreaks in Bt cotton. We first examined the evidence for competitive release of stink bugs through meta-analysis of previous studies. We then experimentally tested if herbivory by Bt-susceptible Helicoverpa zea increases stink bug leaving rates and deters oviposition on non-Bt cotton. Consistent with previous studies, we found differences in leaving rates only for E servus, but we found that both species strongly avoided ovipositing on H. zea-damaged plants. Considering all available evidence, competitive release of stink bug populations in Bt cotton likely contributes to outbreaks, though the relative importance of competitive release remains an open question. Ecological risk assessments of Bt crops and other transgenic insecticidal crops would benefit from greater understanding of the ecological mechanisms underlying non-target pest outbreaks and greater attention to indirect ecological effects more broadly.

Biofuels in Spain: Market penetration analysis and competitiveness in the automotive fuel market

Sobrino, Fernando Hernandez; Monroy, Carlos Rodriguez; Perez, Jose Luis Hernandez

2010-01-01

For several years the European Union (E.U.) has been promoting the use of biofuels due to their potential benefits such as the reduction of dependence on foreign energy imports (the raw materials can be produced within the E.U.), the more stable fossil fuel prices (they can replace fossil fuels on the market), the greenhouse gas (GHG) reduction (biofuels' raw materials fix CO 2 from the atmosphere) and the fact that they can represent an additional source of income for the primary sector (biofuels' raw materials are vegetables that can be grown and harvested). Despite the public aids (direct and indirect), biofuels are not competitive with fossil fuels at present, but it is possible that in the future the environment conditions change and biofuels might become competitive. It is difficult to assess whether this will happen or not, but it is possible to make an assessment of a future situation. This article presents two analyses with one objective: to determine if biofuels might become competitive in the future. The first analysis examines the dependencies of two quotations which have a strong relationship with fuels: the crude oil quotation and the CO 2 bond quotation. The analysis of these relationships may help to forecast the future competitiveness of biofuels. For instance, biofuels' future competitiveness will be higher if their raw material costs are not related to crude oil quotations or if they are related in a negative way (the higher the crude oil quotations the lower the raw material biofuels' cost). The second analysis focuses on the market penetration of biofuels in the Spanish market. There are data related to biofuels monthly consumption in Spain since 2007 and it is possible to know if biofuels are gaining market quota since then. (author)

Technical and economic analyses of hydrogen production via indirectly heated gasification and pyrolysis

Energy Technology Data Exchange (ETDEWEB)

Mann, M.K. [National Renewable Energy Laboratory, Golden, CO (United States)

1995-09-01

Technoeconomic analyses have been conducted on two processes to produce hydrogen from biomass: indirectly-heated gasification of biomass followed by steam reforming of the syngas, and biomass pyrolysis followed by steam reforming of the pyrolysis oil. The analysis of the gasification-based process was highly detailed, including a process flowsheet, material and energy balances calculated with a process simulation program, equipment cost estimation, and the determination of the necessary selling price of hydrogen. The pyrolysis-based process analysis was of a less detailed nature, as all necessary experimental data have not been obtained; this analysis is a follow-up to the preliminary economic analysis presented at the 1994 Hydrogen Program Review. A coproduct option in which pyrolysis oil is used to produce hydrogen and a commercial adhesive was also studied for economic viability. Based on feedstock availability estimates, three plant sizes were studied: 907 T/day, 272 T/day, and 27 T/day. The necessary selling price of hydrogen produced by steam reforming syngas from the Battelle Columbus Laboratories indirectly heated biomass gasifier falls within current market values for the large and medium size plants within a wide range of feedstock costs. Results show that the small scale plant does not produce hydrogen at economically competitive prices, indicating that if gasification is used as the upstream process to produce hydrogen, local refueling stations similar to current gasoline stations, would probably not be feasible.

Aggregation and competitive exclusion: explaining the coexistence of human Papillomavirus types and the effectiveness of limited vaccine conferred cross-immunity.

Science.gov (United States)

Waters, E K

2012-12-01

Human Papillomavirus (HPV) types are sexually transmitted infections that cause a number of human cancers. According to the competitive exclusion principle in ecology, HPV types that have lower transmission probabilities and shorter durations of infection should be outcompeted by more virulent types. This, however, is not the case, as numerous HPV types co-exist, some which are less transmissible and more easily cleared than others. This paper examines whether this exception to the competitive exclusion principle can be explained by the aggregation of infection with HPV types, which results in patchy spatial distributions of infection, and what implications this has for the effect of vaccination on multiple HPV types. A deterministic transmission model is presented that models the patchy distribution of infected individuals using Lloyd's mean crowding. It is first shown that higher aggregation can result in a reduced capacity for onward transmission and reduce the required efficacy of vaccination. It is shown that greater patchiness in the distribution of lower prevalence HPV types permits co-existence. This affirms the hypothesis that the aggregation of HPV types provides an explanation for the violation of the competitive exclusion principle. Greater aggregation of lower prevalence types has important implications where type-specific HPV vaccines also offer cross-protection against non-target types. It is demonstrated that the degree of cross-protection can be less than the degree of vaccine protection conferred against directly targeted types and still result in the elimination of non-target types when these non-target types are patchily distributed.

Climate-driven Sympatry does not Lead to Foraging Competition Between Adélie and Gentoo Penguins

2016-02-01

Climate-driven sympatry may lead to competition for food resources between species, population shifts and changes in ecosystem structure. Rapid warming in the West Antarctic Peninsula (WAP) is coincident with increasing gentoo penguin and decreasing Adélie penguin populations, suggesting that competition for food may exacerbate the Adélie penguin decline. At Palmer Station, we tested for foraging competition between these species by comparing their prey, Antarctic krill, distributions and penguin foraging behaviors on fine scales. To study these predator-prey dynamics, we simultaneously deployed penguin satellite transmitters, and a REMUS autonomous underwater vehicle that acoustically detected krill aggregations and measured physical and biological properties of the water column. We detected krill aggregations within the horizontal and vertical foraging ranges of Adélie and gentoo penguin. In the upper 100 m of the water column, the distribution of krill aggregations were mainly associated with CHL and light, suggesting that krill selected for habitats that balance the need to consume food and avoid predation. Adélie and gentoo penguins mainly had spatially segregated foraging areas but in areas of overlap, gentoo penguins switched foraging behavior by foraging at deeper depths, a strategy which limits competition with Adélie penguins. This suggests that climate-driven sympatry does not necessarily result in competitive exclusion. Contrary to a recent theory, which suggests that increased competition for krill is the major driver of Adélie penguin population declines, we suggest that declines in Adélie penguins along the WAP are more likely due to direct and indirect climate impacts on their life histories.

Indirect measurements of X-ray spectra; Mediciones indirectas de espectros de rayos X

To the effects of measuring the spectral distribution of the radiation emitted by the x-ray tubes and electron accelerators, numerous procedures that are grouped in two big categories exist at the present time: direct and indirect methods. The first ones use high resolution detectors that should be positioned, together with the appropriate collimator, in the direction of the x ray beam. The user should be an expert in the use and correction of the obtained data by the different effects that affect the detector operation such as efficiency and resolution in terms of the energy of the detected radiation. The indirect procedures, although its are more simple to use, its also require a considerable space along the beam to position the ionization chamber and the necessary absorbents to construct by this way the denominated attenuation curve. We will analyze the operation principle of the indirect methods and a new proposal in which such important novelties are introduced as the beam dispersion to avoid to measure along the main beam and that of determination of the attenuation curve in simultaneous form. By this way, with a single shot of the tube, the attenuation curve is measured, being necessary at most a shot of additional calibration to know the relative response of the detectors used in the experimental array. The physical processes involved in the obtaining of an attenuation curve are very well well-known and this it finishes it can be theoretically calculated if the analytic form of the spectrum is supposed well-known. Finally, we will see a spectra reconstruction example with the Kramers parametric form and comparisons with numeric simulations carried out with broadly validated programs as well as the possibility of the use of solid state dosemeters in the obtention of the attenuation curve.

A conceptual framework of game-informed principles for health professions education.

Science.gov (United States)

Ellaway, Rachel H

2016-01-01

Games have been used for training purposes for many years, but their use remains somewhat underdeveloped and under-theorized in health professional education. This paper considers the basis for using serious games (games that have an explicit educational purpose) in health professional education in terms of their underlying concepts and design principles. These principles can be understood as a series of game facets: competition and conflict, chance and luck, experience and performance, simulation and make-believe, tactics and strategies, media, symbols and actions, and complexity and difficulty. Games are distinct and bound in ways that other health professional education activities are not. The differences between games and simulation can be understood in terms of the interconnected concepts of isomorphism (convergence with real-world practice) and anisomorphism (divergence from real-world practice). Gaming facets can extend the instructional design repertoire in health professional education.

Winnerless competition principle and prediction of the transient dynamics in a Lotka-Volterra model

Science.gov (United States)

Afraimovich, Valentin; Tristan, Irma; Huerta, Ramon; Rabinovich, Mikhail I.

2008-12-01

Predicting the evolution of multispecies ecological systems is an intriguing problem. A sufficiently complex model with the necessary predicting power requires solutions that are structurally stable. Small variations of the system parameters should not qualitatively perturb its solutions. When one is interested in just asymptotic results of evolution (as time goes to infinity), then the problem has a straightforward mathematical image involving simple attractors (fixed points or limit cycles) of a dynamical system. However, for an accurate prediction of evolution, the analysis of transient solutions is critical. In this paper, in the framework of the traditional Lotka-Volterra model (generalized in some sense), we show that the transient solution representing multispecies sequential competition can be reproducible and predictable with high probability.

Novel in situ radiotracer methods for the direct and indirect study of chromate adsorption on alumina

International Nuclear Information System (INIS)

Gancs, L.; Nemeth, Z.; Horanyi, G.

2002-01-01

Radiotracer methods, particularly the radiotracer thin foil method, provide unique possibility of in situ monitoring of chromate adsorption on powdered adsorbents. Two different versions of the thin foil method can be distinguished. In the direct method, the species to be studied is labelled and the radiation measured gives direct information on the adsorption of this species. In the indirect method, a different labelled indicator species is added to the system and the adsorption of this species is followed and the adsorption of the species to be studied is determined based on analysis of the competitive adsorption processes. Both methods were used in the present study. In the in situ methods, the radiation measured consists of two main parts, one coming from the solution background, the other originating from the adsorption layer. In the case of the thin foil method using isotopes emitting soft β - radiation or low energy X-ray the solution background is governed and minimised by self-absorption of the radiation. In the direct study we applied an experimental methodology based on the energy selective measurement of the characteristic K α,β X-radiation emitted by the 51 Cr-labelled chromate species, whereas 35 S-labelled sulphate ions were used as the indicator species in the indirect study.

International tests on competences, such as TIMSS or PISA, and knowledge of young students have revealed low average scores in many countries, often unexpectedly. One effective measure to increase the average standard of a population is to bring the last third of the group to a higher level. Therefore, many nations put some effort into this activity. This brings the danger that not enough attention is paid to students at the other end, those who are talented. Indeed, it is a very difficult task for a teacher to support the less able and at the same time challenge the gifted students, to lead them to the limits of their abilities and provide for a smooth transition to university study. Physics competitions have been proven to fulfil these last demands to a large degree, and therefore are an important additional and, to some extent, complementary tool for the promotion of talented students. This third special section on physics competitions in European Journal of Physics contains three papers, each dealing with a different form of science contest. The first continues the series of presentations of tasks performed at the International Young Physicists' Tournament, which was held in Vienna in 2011. First place went to the team from Singapore, and they have put their investigation on vertical oscillations of coupled magnets into written form (not required by the tournament, where an oral presentation and a defence and discussion are the central aspects). Their paper shows how rich in physics this problem is, and what level of solutions high-school students can already achieve. Sadly, those responsible for the organization of last year's International Physics Olympiad did not provide us with a report on this competition. This is unfortunate, since the Olympiad in Zagreb was very successful and, in particular, the experimental tasks were creative and demanding. Very similar to the aims and the execution of the Physics Olympiad is the International Olympiad on Astronomy

Literature suggests that resource acquisition compels competition in young children. However, little is still known about the development of preschool children's competitiveness. In this preliminary study, 166 children (aged 2-4 and 5-6 years) engaged in a dyadic competition which resulted in a winning and a losing group (in a control/non-competition group, participants engaged in a similar task which did not lead to winning/losing outcome), and then experimenters tracked their decisions to compete again with a rival (i.e., an individual they interacted in the previous competition task) and a non-rival competitor (i.e., an anonymous classmate they did not interact in the previous competition task) for a reward, respectively. As expected, results showed an age-related decreasing trend in the percentage of choices to compete with a competitor. However, this age difference was only significant in the control group when participants played with the partner with whom they interacted in the previous game and in the losing group when participants competed with a non-rival competitor. This study contributes to our knowledge of how competitiveness develop in preschool childhood, and calls for further research on the roles of motivation and cognitive control in children's competitiveness.

Full Text Available ABSTRACT Young swimmers are particularly susceptible to the onset of oral diseases. Objective To evaluate the oral health status in young competitive and non-competitive swimmers, involving an assessment of salivary cariogenic bacteria and secretory IgA (S-IgA concentration. Material and Methods Before training sessions (T1, 54 competitive and 69 non-competitive swimmers had the following parameters assessed: decayed, missing, and filled teeth (DMFT, Plaque Index (PlI, and Gingival Index (GI. At T1 and after training sessions (T2, stimulated saliva was collected and microbiological and immunological analyses were performed. Results Competitive swimmers trained 2.02±0.09 hours 5 times a week, while non-competitive swimmers trained 2.03±0.18 hours a week. A total of 14.7% of competitive swimmers suffered dental trauma related to sports. Only 11.76% of the competitive swimmers took a daily dose of fluoride, against 32.65% of non-competitive swimmers (p=0.029. Neither group followed an established diet or presented statistically significant differences in terms of nutritional supplement drink and chocolate intake. There were statistically significant differences in terms of oral hygiene. No significant difference in clinical indexes (DMFT, PlI, and GI was present. S. mutans was harbored by 18.6% of competitive and the 32.2% of non-competitive swimmers. S. sobrinus was detected in 22.03% of competitive and 91.6% of non-competitive swimmers (p<0.05. S. sanguinis was found only in the saliva of competitive swimmers. The average S-IgA of competitive swimmers decreased significantly at T2 (p<0.05. The pool water had a daily average pH of 7.22. Conclusions Microbial markers, immune status and sporting characteristics are important for establishing guidelines for management of training load in order to minimize physical stress and the risk of oral infection.

Full Text Available Since the outburst of the financial crisis, FDI flows into Korea have dramatically increased, causing great concern regarding the rapid penetration of FDI and its concentrating effects on the economy. The study explores the issue of how FDI impacts on market structure and competition in Korea. The preliminary conclusions are that FDI seems to have an upward influence on concentration while at the same time, concentration leads to higher price cost margin, and through this channel, FDI would indirectly contribute to increasing price cost margin. The direct impact of FDI on price cost margin is not conclusive, but seems to suggest that multinationals are attracted to markets where profits are stable (and probably high, but compete profit away as they enter these markets.

Energy levy and competitiveness

International Nuclear Information System (INIS)

Berdowski, P.A.M.

1991-01-01

The principle of regulating levies is that the consumption of products that have negative effects on the environment will be reduced. The income of the levies can be reimbursed to the civilians and companies via tax reduction. One of the impacts of the implementation of energy levies is the negative effect on the competitive position of the Dutch industry and businesses. In this report attention is paid to the micro-economic consequences of energy levies. The flows of fifteen production processes and the position of these processes in the market have been analyzed systematically. The impacts of energy levies on these product flows are investigated. The sectors that have been analyzed are the services sector (mainly determined by households), the agricultural food sector, the transportation sector, and the basic industry (mostly energy-intensive industries). In order to determine the sensitivity of the height of the energy levy three variants were investigated: 25%, 50% and 100% surcharge on the present energy costs. The variants are combined with three geographic levy ranges: national, European and global. 21 figs., 9 tabs

The abundance of exotic plants is thought to be limited by competition with resident species (including plants and generalist herbivores). In contrast, observations in semiarid Chile suggest that a native generalist rodent, the degu (Octodon degus), may be facilitating the expansion of exotic annual plants. We tested this hypothesis with a 20-year data set from a World Biosphere Reserve in mediterranean Chile. In this semiarid environment, rainfall varies annually and dramatically influences cover by both native and exotic annual plants; degu population density affects the composition and cover of exotic and native annual plants. In low-rainfall years, cover of both native and exotic herbs is extremely low. Higher levels of precipitation result in proportional increases in cover of all annual plants (exotic and native species), leading in turn to increases in degu population densities, at which point they impact native herbs in proportion to their greater cover, indirectly favoring the expansion of exotic plants. We propose that bottom-up control of consumers at our site results in top-down indirect facilitation of invasive annual herbs, and that this pattern may be general to other semiarid ecosystems.

Competition-colonization trade-offs, competitive uncertainty, and the evolutionary assembly of species.

Directory of Open Access Journals (Sweden)

Pradeep Pillai

Full Text Available We utilize a standard competition-colonization metapopulation model in order to study the evolutionary assembly of species. Based on earlier work showing how models assuming strict competitive hierarchies will likely lead to runaway evolution and self-extinction for all species, we adopt a continuous competition function that allows for levels of uncertainty in the outcome of competition. We then, by extending the standard patch-dynamic metapopulation model in order to include evolutionary dynamics, allow for the coevolution of species into stable communities composed of species with distinct limiting similarities. Runaway evolution towards stochastic extinction then becomes a limiting case controlled by the level of competitive uncertainty. We demonstrate how intermediate competitive uncertainty maximizes the equilibrium species richness as well as maximizes the adaptive radiation and self-assembly of species under adaptive dynamics with mutations of non-negligible size. By reconciling competition-colonization tradeoff theory with co-evolutionary dynamics, our results reveal the importance of intermediate levels of competitive uncertainty for the evolutionary assembly of species.

A biased competition account of attention and memory in Alzheimer's disease.

2013-10-19

The common view of Alzheimer's disease (AD) is that of an age-related memory disorder, i.e. declarative memory deficits are the first signs of the disease and associated with progressive brain changes in the medial temporal lobes and the default mode network. However, two findings challenge this view. First, new model-based tools of attention research have revealed that impaired selective attention accompanies memory deficits from early pre-dementia AD stages on. Second, very early distributed lesions of lateral parietal networks may cause these attention deficits by disrupting brain mechanisms underlying attentional biased competition. We suggest that memory and attention impairments might indicate disturbances of a common underlying neurocognitive mechanism. We propose a unifying account of impaired neural interactions within and across brain networks involved in attention and memory inspired by the biased competition principle. We specify this account at two levels of analysis: at the computational level, the selective competition of representations during both perception and memory is biased by AD-induced lesions; at the large-scale brain level, integration within and across intrinsic brain networks, which overlap in parietal and temporal lobes, is disrupted. This account integrates a large amount of previously unrelated findings of changed behaviour and brain networks and favours a brain mechanism-centred view on AD.

Romania's Competitiveness and Competitive Position in Global Context

Full Text Available Competitiveness increase has become a primordial framework of the social and economic development strategies of most world countries (mainly the most developed ones over the last decades. The vigorous boost of the contemporary phenomenon of globalization, which has widened the global area of economies, sectors and firms confrontation, has laid an emphasis on their competitiveness importance for their favorable position in the international competition and has therefore force the status to take proper, broad and concerted measures to stimulate the determining factors of action and to take better advantage of their effects. The purpose of the paper is to determine whether an increase in competitiveness could reduce the disparities between regions. The E.U. Member States and regions need significant financial help to solve various structural problems and to achieve their potential of growth. Romania is no exception, one of the main problems being the low rate in attracting European funds.

Diversifying evolution of competitiveness.

Baldauf, Sebastian A; Engqvist, Leif; Weissing, Franz J

2014-10-29

In many species, individuals express phenotypic characteristics that enhance their competitiveness, that is, the ability to acquire resources in competition with others. Moreover, the degree of competitiveness varies considerably across individuals and in time. By means of an evolutionary model, we provide an explanation for this finding. We make the assumption that investment into competitiveness enhances the probability to acquire a high-quality resource, but at the same time reduces the ability of exploiting acquired resources with maximal efficiency. The model reveals that under a broad range of conditions competitiveness either converges to a polymorphic state, where individuals differing in competitive ability stably coexist, or is subject to perpetual transitions between periods of high and low competitiveness. The dynamics becomes even more complex if females can evolve preferences for (or against) competitive males. In extreme cases, such preferences can even drive the population to extinction.

Managing Multiple Sources of Competitive Advantage in a Complex Competitive Environment

Directory of Open Access Journals (Sweden)

Alexandre Howard Henry Lapersonne

2013-12-01

Full Text Available The aim of this article is to review the literature on the topic of sustained and temporary competitive advantage creation, specifically in dynamic markets, and to propose further research possibilities. After having analyzed the main trends and scholars’ works on the subject, it was concluded that a firm which has been experiencing erosion of its core sources of economic rent generation, should have diversified its strategy portfolio in a search for new sources of competitive advantage, ones that could compensate for the decline of profits provoked by intensive competitive environments. This review concludes with the hypothesis that firms, who have decided to enter and manage multiple competitive environments, should have developed a multiple strategies framework approach. The management of this source of competitive advantage portfolio should have allowed persistence of a firm’s superior economic performance through the management of diverse temporary advantages lifecycle and through a resilient effect, where a very successful source of competitive advantage compensates the ones that have been eroded. Additionally, the review indicates that economies of emerging countries, such as the ones from the BRIC block, should present a more complex competitive environment due to their historical nature of cultural diversity, social contrasts and frequent economic disruption, and also because of recent institutional normalization that has turned the market into hypercompetition. Consequently, the study of complex competition should be appropriate in such environments.

Emergence of structural patterns out of synchronization in networks with competitive interactions

Synchronization is a collective phenomenon occurring in systems of interacting units, and is ubiquitous in nature, society and technology. Recent studies have enlightened the important role played by the interaction topology on the emergence of synchronized states. However, most of these studies neglect that real world systems change their interaction patterns in time. Here, we analyze synchronization features in networks in which structural and dynamical features co-evolve. The feedback of the node dynamics on the interaction pattern is ruled by the competition of two mechanisms: homophily (reinforcing those interactions with other correlated units in the graph) and homeostasis (preserving the value of the input strength received by each unit). The competition between these two adaptive principles leads to the emergence of key structural properties observed in real world networks, such as modular and scale-free structures, together with a striking enhancement of local synchronization in systems with no global order.

Synthetic biology has developed rapidly in the 21st century. It covers a range of scientific disciplines that incorporate principles from engineering to take advantage of and improve biological systems, often applied to specific problems. Methods important in this subject area include the systematic design and testing of biological systems and, here, we describe how synthetic biology projects frequently develop microbiology skills and education. Synthetic biology research has huge potential in biotechnology and medicine, which brings important ethical and moral issues to address, offering learning opportunities about the wider impact of microbiological research. Synthetic biology projects have developed into wide-ranging training and educational experiences through iGEM, the International Genetically Engineered Machines competition. Elements of the competition are judged against specific criteria and teams can win medals and prizes across several categories. Collaboration is an important element of iGEM, and all DNA constructs synthesized by iGEM teams are made available to all researchers through the Registry for Standard Biological Parts. An overview of microbiological developments in the iGEM competition is provided. This review is targeted at educators that focus on microbiology and synthetic biology, but will also be of value to undergraduate and postgraduate students with an interest in this exciting subject area. © FEMS 2015.

It is very difficult or often impossible to measure in the lab conditions nuclear cross sections at astrophysically relevant energies. That is why different indirect techniques are used to extract astrophysical information. In this talk different experimental possibilities to get astrophysical information using radioactive and stable beams will be addressed. 1. The asymptotic normalization coefficient (ANC) method. 2. Radiative neutron captures are determined by the spectroscopic factors (SP). A new experimental technique to determine the neutron SPs will be addressed. 3. 'Trojan Horse' is another unique indirect method, which allows one to extract the astrophysical factors for direct and resonant nuclear reactions at astrophysically relevant energies. (author)

Enhanced Indirect Photochemical Transformation of Histidine and Histamine through Association with Chromophoric Dissolved Organic Matter.

Photochemical transformations greatly affect the stability and fate of amino acids (AAs) in sunlit aquatic ecosystems. Whereas the direct phototransformation of dissolved AAs is well investigated, their indirect photolysis in the presence of chromophoric dissolved organic matter (CDOM) is poorly understood. In aquatic systems, CDOM may act both as sorbent for AAs and as photosensitizer, creating microenvironments with high concentrations of photochemically produced reactive intermediates, such as singlet oxygen (1O2). This study provides a systematic investigation of the indirect photochemical transformation of histidine (His) and histamine by 1O2 in solutions containing CDOM as a function of solution pH. Both His and histamine showed pH-dependent enhanced phototransformation in the CDOM systems as compared to systems in which model, low-molecular-weight 1O2 sensitizers were used. Enhanced reactivity resulted from sorption of His and histamine to CDOM and thus exposure to elevated 1O2 concentrations in the CDOM microenvironment. The extent of reactivity enhancement depended on solution pH via its effects on the protonation state of His, histamine, and CDOM. Sorption-enhanced reactivity was independently supported by depressed rate enhancements in the presence of a cosorbate that competitively displaced His and histamine from CDOM. Incorporating sorption and photochemical transformation processes into a reaction rate prediction model improved the description of the abiotic photochemical transformation rates of His in the presence of CDOM.

Against proportional shortfall as a priority-setting principle.

Science.gov (United States)

Altmann, Samuel

2018-05-01

As the demand for healthcare rises, so does the need for priority setting in healthcare. In this paper, I consider a prominent priority-setting principle: proportional shortfall. My purpose is to argue that proportional shortfall, as a principle, should not be adopted. My key criticism is that proportional shortfall fails to consider past health.Proportional shortfall is justified as it supposedly balances concern for prospective health while still accounting for lifetime health, even though past health is deemed irrelevant. Accounting for this lifetime perspective means that the principle may indirectly consider past health by accounting for how far an individual is from achieving a complete, healthy life. I argue that proportional shortfall does not account for this lifetime perspective as it fails to incorporate the fair innings argument as originally claimed, undermining its purported justification.I go on to demonstrate that the case for ignoring past health is weak, and argue that past health is at least sometimes relevant for priority-setting decisions. Specifically, when an individual's past health has a direct impact on current or future health, and when one individual has enjoyed significantly more healthy life years than another.Finally, I demonstrate that by ignoring past illnesses, even those entirely unrelated to their current illness, proportional shortfall can lead to instances of double jeopardy, a highly problematic implication. These arguments give us reason to reject proportional shortfall. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

Variations in the patterns of diversity of symbionts have been described worldwide on Mimosa pudica, a pan-tropical invasive species that interacts with both α and β-rhizobia. In this study, we investigated if symbiont competitiveness can explain these variations and the apparent prevalence of β- over α-rhizobia. We developed an indirect method to measure the proportion of nodulation against a GFP reference strain and tested its reproducibility and efficiency. We estimated the competitiveness of 54 strains belonging to four species of β-rhizobia and four of α-rhizobia, and the influence of the host genotype on their competitiveness. Our results were compared with biogeographical patterns of symbionts and host varieties. We found: (i) a strong strain effect on competitiveness largely explained by the rhizobial species, with Burkholderia phymatum being the most competitive species, followed by B. tuberum, whereas all other species shared similar and reduced levels of competitiveness; (ii) plant genotype can increase the competitiveness of Cupriavidus taiwanensis. The latter data support the likelihood of the strong adaptation of C. taiwanensis with the M. pudica var. unijuga and help explain its prevalence as a symbiont of this variety over Burkholderia species in some environments, most notably in Taiwan. © 2013 Society for Applied Microbiology and John Wiley & Sons Ltd.

Cooperation is a hallmark of human society. Humans often cooperate with strangers even if they will not meet each other again. This so-called indirect reciprocity enables large-scale cooperation among nonkin and can occur based on a reputation mechanism or as a succession of pay-it-forward behavior. Here, we provide the functional and anatomical neural evidence for two distinct mechanisms governing the two types of indirect reciprocity. Cooperation occurring as reputation-based reciprocity specifically recruited the precuneus, a region associated with self-centered cognition. During such cooperative behavior, the precuneus was functionally connected with the caudate, a region linking rewards to behavior. Furthermore, the precuneus of a cooperative subject had a strong resting-state functional connectivity (rsFC) with the caudate and a large gray matter volume. In contrast, pay-it-forward reciprocity recruited the anterior insula (AI), a brain region associated with affective empathy. The AI was functionally connected with the caudate during cooperation occurring as pay-it-forward reciprocity, and its gray matter volume and rsFC with the caudate predicted the tendency of such cooperation. The revealed difference is consistent with the existing results of evolutionary game theory: although reputation-based indirect reciprocity robustly evolves as a self-interested behavior in theory, pay-it-forward indirect reciprocity does not on its own. The present study provides neural mechanisms underlying indirect reciprocity and suggests that pay-it-forward reciprocity may not occur as myopic profit maximization but elicit emotional rewards.

The diversity of indirect interactions that can occur within communities is large. Recent research on indirect interactions is scattered in the literature under numerous labels. The definition of indirect effects is an important aspect of their study, and clarifies some of the subtle differences among indirect effects found in natural communities. Choosing which species to study, how to manipulate species and for what duration, which attributes to measure and, finally, which analytical techniques to use are all problems facing the community ecologist. Ultimately, we are striving for the best means of determining the relative importance of direct and indirect effects in structuring communities. Copyright © 1991. Published by Elsevier Ltd.

Preschool children's behavioral tendency toward social indirect reciprocity.

Directory of Open Access Journals (Sweden)

Mayuko Kato-Shimizu

Full Text Available Social indirect reciprocity seems to be crucial in enabling large-scale cooperative networks among genetically unrelated individuals in humans. However, there are relatively few studies on social indirect reciprocity in children compared to adults. Investigating whether young children have a behavioral tendency toward social indirect reciprocity will help us understand how and when the fundamental ability to form cooperative relationships among adults is acquired. Using naturalistic observation at a nursery school, this study examined whether 5- to 6-year-olds show a behavioral tendency to engage in social indirect reciprocity in response to their peers' prosocial behavior toward a third party. The results revealed that bystander children tended to display prosocial behavior toward their peers more frequently after observing these peers' prosocial behavior toward third-party peers, compared with control situations; this suggests that 5- to 6-year-olds may have an essential behavioral tendency to establish social indirect reciprocity when interacting with peers in their daily lives. In addition, bystanders tended to display affiliative behavior after observing focal children's prosocial behavior. In other words, observing peers' prosocial behavior toward third-party peers evoked bystanders' positive emotions toward the helpers. Considering both the present results and previous findings, we speculate that in preschoolers, such positive emotions might mediate the increase in the bystander's prosocial behavior toward the helper. In addition, an intuitional emotional process plays an important role in the preschooler's behavioral tendency toward social indirect reciprocity in natural interactions with peers.

Separating astrophysical sources from indirect dark matter signals

2015-01-01

Indirect searches for products of dark matter annihilation and decay face the challenge of identifying an uncertain and subdominant signal in the presence of uncertain backgrounds. Two valuable approaches to this problem are (i) using analysis methods which take advantage of different features in the energy spectrum and angular distribution of the signal and backgrounds and (ii) more accurately characterizing backgrounds, which allows for more robust identification of possible signals. These two approaches are complementary and can be significantly strengthened when used together. I review the status of indirect searches with gamma rays using two promising targets, the Inner Galaxy and the isotropic gamma-ray background. For both targets, uncertainties in the properties of backgrounds are a major limitation to the sensitivity of indirect searches. I then highlight approaches which can enhance the sensitivity of indirect searches using these targets. PMID:25304638

The leading aim of a seismic design is, besides protection against seismic impacts, not to enhance the overall risk in the absence of seismic vibrations and, secondly, to avoid competition between operational needs and a seismic structural design. This approach is supported by avoiding overconservatism in the assumption of seismic loads and in the calculation of the structural response. Accordingly the seismic principles are stated as follows: restriction to German or equivalent low seismicity sites with intensities (SSE) lower VIII at frequency lower than 10 -4 /year; best estimate of seismic input-data without further conservatism; no consideration of OBE. The structural design principles are: 1. The secondary character of the seismic excitation is explicitly accounted for; 2. Energy absorption is allowed for by ductility of materials and construction. Accordingly strain criteria are used for failure predictions instead of stress criteria. (author). 1 fig

Indirect Tire Monitoring System - Machine Learning Approach

The heavy vehicle industry has today no requirement to provide a tire pressure monitoring system by law. This has created issues surrounding unknown tire pressure and thread depth during active service. There is also no standardization for these kind of systems which means that different manufacturers and third party solutions work after their own principles and it can be hard to know what works for a given vehicle type. The objective is to create an indirect tire monitoring system that can generalize a method that detect both incorrect tire pressure and thread depth for different type of vehicles within a fleet without the need for additional physical sensors or vehicle specific parameters. The existing sensors that are connected communicate through CAN and are interpreted by the Drivec Bridge hardware that exist in the fleet. By using supervised machine learning a classifier was created for each axle where the main focus was the front axle which had the most issues. The classifier will classify the vehicles tires condition and will be implemented in Drivecs cloud service where it will receive its data. The resulting classifier is a random forest implemented in Python. The result from the front axle with a data set consisting of 9767 samples of buses with correct tire condition and 1909 samples of buses with incorrect tire condition it has an accuracy of 90.54% (0.96%). The data sets are created from 34 unique measurements from buses between January and May 2017. This classifier has been exported and is used inside a Node.js module created for Drivecs cloud service which is the result of the whole implementation. The developed solution is called Indirect Tire Monitoring System (ITMS) and is seen as a process. This process will predict bad classes in the cloud which will lead to warnings. The warnings are defined as incidents. They contain only the information needed and the bandwidth of the incidents are also controlled so incidents are created within an

Approximate kernel competitive learning.

Kernel competitive learning has been successfully used to achieve robust clustering. However, kernel competitive learning (KCL) is not scalable for large scale data processing, because (1) it has to calculate and store the full kernel matrix that is too large to be calculated and kept in the memory and (2) it cannot be computed in parallel. In this paper we develop a framework of approximate kernel competitive learning for processing large scale dataset. The proposed framework consists of two parts. First, it derives an approximate kernel competitive learning (AKCL), which learns kernel competitive learning in a subspace via sampling. We provide solid theoretical analysis on why the proposed approximation modelling would work for kernel competitive learning, and furthermore, we show that the computational complexity of AKCL is largely reduced. Second, we propose a pseudo-parallelled approximate kernel competitive learning (PAKCL) based on a set-based kernel competitive learning strategy, which overcomes the obstacle of using parallel programming in kernel competitive learning and significantly accelerates the approximate kernel competitive learning for large scale clustering. The empirical evaluation on publicly available datasets shows that the proposed AKCL and PAKCL can perform comparably as KCL, with a large reduction on computational cost. Also, the proposed methods achieve more effective clustering performance in terms of clustering precision against related approximate clustering approaches. Copyright © 2014 Elsevier Ltd.

Narrow bandgap and its tuning are important aspects of materials for their technological applications. In this context group IV-VI semiconductors are one of the interesting candidates. In this paper, we explore the possibility of bandgap tuning in one of the family member of this family GeSe by using isoelectronic Pb doping. Our study is first-principles based electronic structure calculations of Ge1-xPbxSe. This study reveals that the Ge-p and Se-p states are strongly hybridized in GeSe and shows a gap in the DOS at Ef in GeSe. This gap reduces systematically with simultaneous enhancement of the states in the near Ef region as a function of Pb doping. This leads tuning of the indirect bandgap in GeSe via Pb doping. The results of the indirect bandgap decrement are consistent with the experimental findings. We propose a mechanism where the electrostatic effect of dopant Pb cation could be responsible for these changes in the electronic structure of GeSe.

Coal competitiveness?

International Nuclear Information System (INIS)

Rogeaux, B.

2006-01-01

Will coal electrical plants be more competitive in the coming years? Answering this one cannot be limited to merely comparing estimates based on reference electricity production costs. The competitiveness of coal will indeed depend on the final product marketed, as the MWhs are not equal: is the purpose to produce base, half-base MWh? Does the electrical equipment structure require flexible MWh (for instance in the event of significant intermittent renewable energy amounts), and therefore plants able to adjust their power rapidly? But the competitiveness of coal will also depend on many factors that will correct reference cost estimates: uncertainties, risks, externalities. These factors will need to be appreciated on a case by case basis. We introduce some of the reasoning used to better appreciate the future competitiveness of coal, and the main factors conditioning it in three contrasting regions of the world: Europe, USA, china.

Full Text Available Analyzing products and services around us it is clear that most of them are the result of production factors, labor and capital becoming more international and increasingly less and less national. We are witnessing the globalization of markets and production, to a large global integration and interdependence, increase personalization of production and services as a result of new communication systems interaction and flexible production processes. Markets will continue to homogenize and diversify at the same time, so it is important that as a global marketer one addresses a market segment defined by income, age, and consumption habits and not by membership of a nation. The most visible and polarized is the premium segment fighting for high income clients where brand value plays an important role. Instead identification of large segments of customers offers the advantages of scale economy in production and marketing for global enterprises. Consumer profile is the dominant global consumer requesting and accepting global products and services easily. In fact, what can force an economic alignment to achieve the best performance, rather than the global consumer. The research methodology used includes literature review, comparative analysis, synthesis of data based on bibliographic resources and official documents.The aim of the paper is to highlight current models that underlie the competitive advantage of nations and assess the competitive advantage of Romania in the context of the global market. A case study is used to offer an overview of competitive advantage of Antibiotice Iasi SA, a competitive player, in a global pharmaceutical market with strong global competition. Countries moderate companies’ achievements of global efficiency objectives due to the countries’ rivalry. Romania has to understand that it is in competition with other countries in order to fulfill economic, political and social objectives. The scope in the end is the well

Full Text Available Abstract—Matrix Converter (MC is a modern direct AC/AC electrical power converter without dc-link capacitor. MC is operated in four quadrant, assuring a control of the output voltage, amplitude and frequency. The matrix converter has recently attracted significant attention among researchers and it has become increasing attractive for applications of wind energy conversion, military power supplies, induction motor drives, etc. Recently, different MC topologies have been proposed and developed which have their own advantages and disadvantages. Matrix converter can be classified as direct and indirect structures. The direct one has been elaborated in previous work. In this paper the indirect MCs are reviewed. Different characteristics of the indirect MC topologies are mentioned to show the strengths and weaknesses of such converter topologies.

Studies of facilitative interactions as drivers of plant richness along environmental gradients often assume the existence of an overarching stress gradient equally affecting the performance of all the species in a given community. However, co-existing species differ in their ecophysiological adaptations, and do not experience the same stress level under particular environmental conditions. Moreover, these studies assume a unimodal richness-biomass curve, which is not as general as previously thought. We ignored these assumptions to assess changes in plant-plant interactions, and their effect on local species richness, across environmental gradients in semi-arid areas of Spain and Australia. We aimed to understand the relative importance of direct (microhabitat amelioration) and indirect (changes in the competitive relationships among the understorey species: niche segregation, competitive exclusion or intransitivity) mechanisms that might underlie the effects of nurse plants on local species richness. By jointly studying these direct and indirect mechanisms using a unifying framework, we were able to see how our nurse plants (trees, shrubs and tussock grasses) not only increased local richness by expanding the niche of neighbouring species, but also by increasing niche segregation among them, though the latter was not important in all cases. The outcome of the competition-facilitation continuum changed depending on the study area, likely because the different types of stress gradient considered. When driven by both rainfall and temperature, or rainfall alone, the community-wide importance of nurse plants remained constant (Spanish sites), or showed a unimodal relationship along the gradient (Australian sites). This study expands our understanding of the relative roles of plant-plant interactions and environmental conditions as drivers of local species richness in semi-arid environments. These results can also be used to refine predictions about the response of

As expected, results showed an age-related decreasing trend in the percentage of choices to compete with a competitor. However, this age difference was only significant in the control group when participants played with the partner with whom they interacted in the previous game and in the losing group when participants competed with a non-rival competitor. This study contributes to our knowledge of how competitiveness develop in preschool childhood, and calls for further research on the roles of motivation and cognitive control in children’s competitiveness.

On Russian/Nordic Investment Competition in the Baltic States

Olenchenko Vladimir

2015-06-01

Full Text Available The researchers often overlook the relationships between Russian and Nordic investment capital; and even less attention is paid to studying the competition between the two. Yet this subject can be of particular relevance to the areas that are geographically, historically and culturally close to both Russia and the Nordic countries. Thus, the aim of this article is to understand how the competition between Russian and Nordic capital investment is played out in the Baltic States. The study discusses the principles of Russian and Nordic investment in the Baltic, and suggests ways to regulate these relations. To this end, we compare the investment conditions created in the Baltic States for both Russian and Nordic investors. The analysis shows that most of the Baltic market is controlled by the Nordic capital, which blocks the arrival of Russian investment to the Baltic States. With a nod to a number of previous studies, the authors of this article suggest some adjustments to the theory of foreign direct investment. The study will be also of practical interest to those Russian investors who are seeking entry points to the Baltic markets.

The Influence of Direct and Indirect Speech on Source Memory

Anita Eerland

2018-02-01

Full Text Available People perceive the same situation described in direct speech (e.g., John said, “I like the food at this restaurant” as more vivid and perceptually engaging than described in indirect speech (e.g., John said that he likes the food at the restaurant. So, if direct speech enhances the perception of vividness relative to indirect speech, what are the effects of using indirect speech? In four experiments, we examined whether the use of direct and indirect speech influences the comprehender’s memory for the identity of the speaker. Participants read a direct or an indirect speech version of a story and then addressed statements to one of the four protagonists of the story in a memory task. We found better source memory at the level of protagonist gender after indirect than direct speech (Exp. 1–3. When the story was rewritten to make the protagonists more distinctive, we also found an effect of speech type on source memory at the level of the individual, with better memory after indirect than direct speech (Exp. 3–4. Memory for the content of the story, however, was not influenced by speech type (Exp. 4. While previous research showed that direct speech may enhance memory for how something was said, we conclude that indirect speech enhances memory for who said what.

Indirect reciprocity and the evolution of "moral signals"

Science.gov (United States)

Smead, Rory

2010-01-01

Signals regarding the behavior of others are an essential element of human moral systems and there are important evolutionary connections between language and large-scale cooperation. In particular, social communication may be required for the reputation tracking needed to stabilize indirect reciprocity. Additionally, scholars have suggested that the benefits of indirect reciprocity may have been important for the evolution of language and that social signals may have coevolved with large-scale cooperation. This paper investigates the possibility of such a coevolution. Using the tools of evolutionary game theory, we present a model that incorporates primitive "moral signaling" into a simple setting of indirect reciprocity. This model reveals some potential difficulties for the evolution of "moral signals." We find that it is possible for "moral signals" to evolve alongside indirect reciprocity, but without some external pressure aiding the evolution of a signaling system, such a coevolution is unlikely.

Full Text Available Objective: To explore the indirect self-destructiveness syndrome in patients with schizophrenia. Methods: Two hundred individuals with paranoid schizophrenia (117 men and 83 women, mean age 37.15 years, all in remission, were examined using the Polish version of the Chronic Self-Destructiveness Scale. Two hundred well-matched healthy individuals served as a control group. Results: The intensity of indirect self-destructiveness was greater in the schizophrenia group than in controls. The intensity of each manifestation was as follows (in decreasing order: helplessness and passiveness in the face of difficulties (A5, personal and social neglects (A3, lack of planfulness (A4, poor health maintenance (A2, transgression and risk (A1. Conclusion: Patients with schizophrenia displayed more behaviors that were indirectly self-destructive than healthy controls; they scored better than healthy controls only on caring for their own health. The patients showed the lowest intensity of behaviors connected with the active form of indirect self-destructiveness, and the highest intensity of behaviors connected with the passive form. These findings may enable delivery of more effective forms of pharmacological and psychosocial help to patients with schizophrenia.

Epidemic spreading through direct and indirect interactions.

Ganguly, Niloy; Krueger, Tyll; Mukherjee, Animesh; Saha, Sudipta

2014-09-01

In this paper we study the susceptible-infected-susceptible epidemic dynamics, considering a specialized setting where popular places (termed passive entities) are visited by agents (termed active entities). We consider two types of spreading dynamics: direct spreading, where the active entities infect each other while visiting the passive entities, and indirect spreading, where the passive entities act as carriers and the infection is spread via them. We investigate in particular the effect of selection strategy, i.e., the way passive entities are chosen, in the spread of epidemics. We introduce a mathematical framework to study the effect of an arbitrary selection strategy and derive formulas for prevalence, extinction probabilities, and epidemic thresholds for both indirect and direct spreading. We also obtain a very simple relationship between the extinction probability and the prevalence. We pay special attention to preferential selection and derive exact formulas. The analysis reveals that an increase in the diversity in the selection process lowers the epidemic thresholds. Comparing the direct and indirect spreading, we identify regions in the parameter space where the prevalence of the indirect spreading is higher than the direct one.

An indecent proposal: the dual functions of indirect speech.

Chakroff, Aleksandr; Thomas, Kyle A; Haque, Omar S; Young, Liane

2015-01-01

People often use indirect speech, for example, when trying to bribe a police officer by asking whether there might be "a way to take care of things without all the paperwork." Recent game theoretic accounts suggest that a speaker uses indirect speech to reduce public accountability for socially risky behaviors. The present studies examine a secondary function of indirect speech use: increasing the perceived moral permissibility of an action. Participants report that indirect speech is associated with reduced accountability for unethical behavior, as well as increased moral permissibility and increased likelihood of unethical behavior. Importantly, moral permissibility was a stronger mediator of the effect of indirect speech on likelihood of action, for judgments of one's own versus others' unethical action. In sum, the motorist who bribes the police officer with winks and nudges may not only avoid public punishment but also maintain the sense that his actions are morally permissible.

2013-01-01

In the context of National Ignition Facility Basic Science program we propose to study on the NIF ablative Rayleigh-Taylor (RT) instability in transition from weakly nonlinear to highly nonlinear regimes. Based on the analogy between flame front and ablation front, highly nonlinear RT instability measurements at the ablation front can provide important insights into the initial deflagration stage of thermonuclear supernovae of type Ia. NIF provides a unique platform to study the rich physics of nonlinear and turbulent mixing flows in High Energy Density plasmas because it can accelerate targets over much larger distances and longer time periods than previously achieved on the NOVA and OMEGA lasers. In one shot, growth of RT modulations can be measured from the weakly nonlinear stage near nonlinear saturation levels to the highly nonlinear bubble-competition, bubble-merger regimes and perhaps into a turbulent-like regime. The role of ablation on highly-nonlinear RT instability evolution will be comprehensively studied by varying ablation velocity using indirect and direct-drive platforms. We present a detailed hydro-code design of the indirect-drive platform and discuss the implementation plan for these experiments which only use NIF diagnostics already qualified. (authors)

The current business environment is characterized by increased competition and highly innovative approach, in order to create products and services to better respond to the costumers’ needs and expectations. In this specific context, the research approaches need to be more flexible and business oriented and so, throughout the paper we have used a research method that combines design research and action research, named Action Design Research which is a research method used for generating prescriptive design knowledge through building and evaluating IT artifacts in an organizational setting [1]. Following the Action Design Research stages and principles: problem identification, building, intervention and evaluation, reflection and learning and formalization of learning, the research team has developed an online instrument used to actively involve the consumer in the product development process, in order to generate a better consumers insight regarding their needs and desires and to design and/or adjust the product accordingly. The customer engagement IT tool created and tested by using Action Design Research, E-PICUS, has been developed within the framework of the research project „E-solutions for innovation through customer pro-active involvement in value creation to increase organisational competitiveness (E-PICUS)”, PN- II-PT-PCCA-2013-4-1811, currently undergoing.

Predatory fishes affect trophic cascades and apparent competition in temperate reefs.

We provide evidence for a trophic cascade involving apex predators and mesopredators of marine temperate reefs, lingcod and rockfish, respectively. We measured spatio-temporal variation in the relative abundance of lingcod, subadult rockfish and two shrimp groups eaten by rockfish (Pandalus sp. and three smaller-bodied genera aggregated). Lingcod had an indirect positive effect on shrimps, as mediated by the direct negative effects of lingcod on rockfish and of rockfish on shrimps. These top-down effects on shrimps, however, were stronger for Pandalus than for small-bodied shrimps. Further, abundances of Pandalus and small-bodied shrimps were negatively correlated and the latter had a stronger positive effect on rockfish, suggesting that rockfish mediated asymmetrical apparent competition between shrimps. Our results indicate mechanisms by which predatory fishes may influence the structure of marine communities.

Competition policy and environmental protection, obstacles to competition in the waste sector

This study deals with the legal rules that affect the conditions of competition in the waste sector at both the EU level and national level in Finland. This study describes further, on a more general level, the relation between the EC's internal market rules and competition rules and the actions involving environmental protection taken by public authorities (EG, Member States) and enterprises. Hazardous waste is not studied in this report. The study comprises two parts: The first part deals with the free movement of waste, EG rules on the transportation of waste between Member States, and the specific EG rules and Finnish laws and regulations on waste. The aim of this study has been, on the one hand, to discuss cases where restrictions of competition in the waste sector are a direct consequence of EG rules on waste and, on the other hand, situations where EG rules or the large margin of manoeuvre left with the Member States create problems with a view to a well functioning competition at the national level. Part two deals with the application of EG rules and Finnish competition rules to companies' agreements on actions involving environmental protection and especially waste management, and to their operations in general and, in certain cases, also to the measures taken by Member States. The EG rules on waste do not pay enough attention to competition aspects. The different requirements set by Member States result in distortion of competition while the rules governing the shipments of waste are not effective enough. From the internal market point of view, more binding and detailed rules are motivated. Competition rules are fully applicable to enterprises' measures aimed at environmental protection that restrict competition. Environmental protection aspects in connection with a case-to-case consideration of interests is, however, gaining importance. Those restrictions of competition in the waste sector that EC has dealt with have without exception concerned the

Migratory herds of wildebeests and zebras indirectly affect calf survival of giraffes.

In long-distance migratory systems, local fluctuations in the predator-prey ratio can exhibit extreme variability within a single year depending upon the seasonal location of migratory species. Such systems offer an opportunity to empirically investigate cyclic population density effects on short-term food web interactions by taking advantage of the large seasonal shifts in migratory prey biomass.We utilized a large-mammal predator-prey savanna food web to evaluate support for hypotheses relating to the indirect effects of "apparent competition" and "apparent mutualism" from migratory ungulate herds on survival of resident megaherbivore calves, mediated by their shared predator. African lions ( Panthera leo ) are generalist predators whose primary, preferred prey are wildebeests ( Connochaetes taurinus ) and zebras ( Equus quagga ), while lion predation on secondary prey such as giraffes ( Giraffa camelopardalis ) may change according to the relative abundance of the primary prey species.We used demographic data from five subpopulations of giraffes in the Tarangire Ecosystem of Tanzania, East Africa, to test hypotheses relating to direct predation and indirect effects of large migratory herds on calf survival of a resident megaherbivore. We examined neonatal survival via apparent reproduction of 860 adult females, and calf survival of 449 giraffe calves, during three precipitation seasons over 3 years, seeking evidence of some effect on neonate and calf survival as a consequence of the movements of large herds of migratory ungulates.We found that local lion predation pressure (lion density divided by primary prey density) was significantly negatively correlated with giraffe neonatal and calf survival probabilities. This supports the apparent mutualism hypothesis that the presence of migratory ungulates reduces lion predation on giraffe calves.Natural predation had a significant effect on giraffe calf and neonate survival, and could significantly affect giraffe

Full Text Available Background: The current study estimated (a the indirect costs associated with non-fatal disability and premature death across a wide range of diseases and health conditions in Africa in 2015 and (b the potential savings that could be accrued if countries were to meet the 3 health targets of the substainable development goal (SDG compared to the costs under the status quo. Methods: This study used the lost output or human capital approach to quantify the gross domestic product (GDP losses associated with the disability-adjusted-life-years (DALYs lost due to all causes by age group as well as by country economic classification (Group 1: 10 high/upper-middle income countries; Group 2: 17 lower-middle income countries; and Group 3: 27 low income countries. Results: The expected indirect cost of the 704,765,879 DALYs lost in Africa in 2015 was Int$ 2,983,187,560,197. Of this amount, 25.17%, 57.84% and 16.99% were incurred by the economies of the countries comprising Group 1, Group 2 and Group 3, respectively. Of the total continental indirect cost, 36.9%, 10.5%, 13.7%, 17.0%, 7.6%, 6.8% and 7.5% were associated with people aged 0-4, 5-14, 15-29, 30-49, 50-59, 60-69 and 70 years or older, respectively. Most of the total indirect cost (56.61% was attributable to maternal conditions, AIDS, tuberculosis (TB, malaria, neglected tropicald diseases (NTDs, non-communicable diseases and traffic injuries. Approximately half (47% of this cost could be avoided (or saved every year if the 3 (health targets of the SDG were fully met. Conclusion: The study estimated the total indirect cost of illness due to all causes by age group and country economic classification. The annual indirect cost is substantial. The findings contained in this paper suggest that health system strengthening should focus on both rich and poor countries, people of all ages and specific disease categories.

A hierarchy of complexity exists in plant characteristics. The efficiency of indirect selection for a complex characteristic by a sub-trait depends on the heritability of the complex characteristic (hsub(c)), the heritability of the sub-trait (hsub(s)), and the genotypic correlation between sub-trait and complex characteristic (rsub(s.c)). In 1961 hsub(s)Xrsub(s.c)>hsub(c) was postulated, when indirect selection becomes more efficient than direct selection. Numerical examples for this relationship are given and a table for indirect selection for yield in wheat is elaborated. Efficiency ranking of sub-traits in indirect selection may change with climate, conditions of cultivation, the level of other sub-traits, the level of the complex characteristic already reached by breeding, and the breeding material. An example shows that regression analysis for different sub-traits on the same complex characteristic, and an estimation of the differences of the within - and the between - variety slopes, may help to select the more efficient sub-trait. In another example, where simultaneous selection was made for two polygenic characteristics, one directly and the other indirectly by two sub-traits, less than half the F 5 -lines had to be continued, when using the more efficient sub-trait.

Directionality Theory and the Entropic Principle of Natural Selection

Directory of Open Access Journals (Sweden)

Full Text Available Darwinian fitness describes the capacity of an organism to appropriate resources from the environment and to convert these resources into net-offspring production. Studies of competition between related types indicate that fitness is analytically described by entropy, a statistical measure which is positively correlated with population stability, and describes the number of accessible pathways of energy flow between the individuals in the population. Directionality theory is a mathematical model of the evolutionary process based on the concept evolutionary entropy as the measure of fitness. The theory predicts that the changes which occur as a population evolves from one non-equilibrium steady state to another are described by the following directionality principle–fundamental theorem of evolution: (a an increase in evolutionary entropy when resource composition is diverse, and resource abundance constant; (b a decrease in evolutionary entropy when resource composition is singular, and resource abundance variable. Evolutionary entropy characterizes the dynamics of energy flow between the individual elements in various classes of biological networks: (a where the units are individuals parameterized by age, and their age-specific fecundity and mortality; where the units are metabolites, and the transitions are the biochemical reactions that convert substrates to products; (c where the units are social groups, and the forces are the cooperative and competitive interactions between the individual groups. % This article reviews the analytical basis of the evolutionary entropic principle, and describes applications of directionality theory to the study of evolutionary dynamics in two biological systems; (i social networks–the evolution of cooperation; (ii metabolic networks–the evolution of body size. Statistical thermodynamics is a mathematical model of macroscopic behavior in inanimate matter based on entropy, a statistical measure which

On surveys that assess sensitive personal attributes, indirect questioning aims at increasing respondents' willingness to answer truthfully by protecting confidentiality. However, the assumption that subjects understand questioning procedures fully and trust them to protect their privacy is rarely tested. In a scenario-based design, we compared four indirect questioning procedures in terms of their comprehensibility and perceived privacy protection. All indirect questioning techniques were found to be less comprehensible by respondents than a conventional direct question used for comparison. Less-educated respondents experienced more difficulties when confronted with any indirect questioning technique. Regardless of education, the crosswise model was found to be the most comprehensible among the four indirect methods. Indirect questioning in general was perceived to increase privacy protection in comparison to a direct question. Unexpectedly, comprehension and perceived privacy protection did not correlate. We recommend assessing these factors separately in future evaluations of indirect questioning.

Enzyme-linked immunosorbent assays (ELISAs) are investigated in this work for the detection of bisphenol-A (BPA), a plastic monomer and a critical contaminant in food and environment. A series of polyclonal antibodies generated in vivo using BPA-butyrate-protein conjugate and BPA-valerate-protein conjugate were evaluated on direct and indirect competitive assay formats with five competing haptens (BPA-butyrate, BPA-valerate, BPA-crotonate, BPA-acetate, and BPA-2-valerate). Two indirect ELISAs and one direct ELISA exhibiting high sensitivity and specificity for BPA were developed. The 50 % inhibition of antibody binding (IC(50)) values were 0.78 ± 0.01-1.20 ± 0.26 μg L(-1), and the limits of detection as measured by the IC(20) values were 0.10 ± 0.03-0.20 ± 0.04 μg L(-1). The assays were highly specific to BPA, only displaying low cross-reactivity (3-8 % for the indirect assays and 26 % for the direct assay) for 4-cumylphenol (4-CP), at pH 7.2. The degree of cross-reaction of 4-CP was influenced by the antibody/hapten conjugate combination, assay conditions, and the assay format. The assays were optimized for the analysis of BPA in canned vegetables, bottled water and carbonated drinks. The limits of quantification for these three evaluated sample types, based on the spike and recovery data, were 0.5, 2.5, and 100 μg L(-1), respectively.

This paper develops a framework for measuring “tipping”—the increase in a firm's market share dominance caused by indirect network effects. Our measure compares the expected concentration in a market to the hypothetical expected concentration that would arise in the absence of indirect network effects. In practice, this measure requires a model that can predict the counterfactual market concentration under different parameter values capturing the strength of indirect network effects. We build...

The purpose of the study was to examine the association between belief types and the magnitude of indirect traumatization. Specific types of beliefs were defined in terms of the cognitive orientation theory, which is a cognitive-motivational approach to the understanding, predicting, and changing of behaviors. Belief types that were analyzed included beliefs about self, general beliefs, beliefs about norms, and goal beliefs as they relate to personal growth. Study participants included 38 rescuers (body handlers), 37 nurses, and 31 rehabilitation workers who treated injured civilians that had been exposed to politically motivated violence. The Cognitive Orientation for Posttraumatic Growth Scale was used to assess beliefs about personal growth. The Revised Posttraumatic Stress Disorder Inventory was administered to evaluate indirect traumatization. The results indicate that three of the four belief types related to personal growth were associated with the level of indirect traumatization. Optimistic and positive beliefs about self and general beliefs were associated with a lower level of indirect traumatization symptomatology, suggesting that these types of beliefs may counteract indirect traumatization. On the other hand, stronger goal beliefs were associated with greater indirect traumatization. The negative association between positive goal beliefs and indirect trauma may be related to the gap the individual perceives between the hoped-for ideals and the trauma-stricken reality. These results indicate the importance of cognitive beliefs and their possible role in determining the response to indirect traumatization.

Direct versus indirect detection of supersymmetric dark matter

International Nuclear Information System (INIS)

2003-01-01

This document gathers the slides that were presented during the workshop 'direct versus indirect detection of supersymmetric dark matter'(about 30 contributions). This workshop intended to bring together people from the particle theory community, astrophysicists and cosmologists, as well as experimentalists involved in the detection of dark matter. The aim is to generate a discussion about current and future strategies for detection of SUSY dark matter (with focus, but not exclusively, on neutralinos). Complementarities between accelerator, direct and indirect searches as well as a comparison between the uncertainties in direct and indirect searches of dark matter, are supposed to be discussed. Among the issues which will be addressed are: -) the crucial questions related to the structure of galaxies (local dark matter density, clumping, anomalous velocity distributions, etc.) ; -) the possibilities offered by the present and future experimental facilities for direct and indirect (photon, neutrino) searches; -) the potential for the discovery of SUSY at LHC and beyond; and -) the parameterization of the SUSY breaking models beyond the minimal versions

Who is responsible for the team’s results? Media framing of sports actors’ responsibility in major sports competitions

Full Text Available Media are no longer just a witness to sports events, facilitating our access to them, but have become the most powerful judging platform for sports competitions, serving as a guide for their interpretation and evaluation. The present study focuses on media framing of sports actors’ responsibility when it comes to major sports competitions. Who is responsible for the team’s performance and results? In analysing media discourse, framing effects of sports events coverage will be examined from two inter-correlated dimensions, textually and visually. Based on an event-related corpus of on-line press articles from four national newspapers, this case study covers two major sports events: 2010 European Women’s Handball Championship and 2011 World Women’s Handball Championship. The discursive analysis of the press articles shows that, if winning competitive settings favour the emergence of a personification effect, building up sports heroes on both textual and visual dimensions, the responsibility of failure is rather diffused towards a collective referent. However, the visual component of press articles, along with the indirect strategy of addressing the responsibility issue throughout reported speech techniques, works as an alternative to the personification effect.

Full Text Available In today’s dynamic business environment, a key challenge for all companies is to make adaptive adjustments to their manufacturing strategy. This study demonstrates the competitive priorities of manufacturing strategy in hydro-power case company to evaluate the level of sustainable competitive advantage and also to further analyze how business strategies are aligned with manufacturing strategies. This research is based on new holistic analytical evaluation of manufacturing strategy index, sense and respond, and sustainable competitive advantage models. These models help to describe, evaluate, and optimize resource allocation to meet the performance requirements in dynamic decision making. Furthermore, these models evaluate operational competitiveness for manufacturing strategies according to the multi-criteria priority. The results show that the adjustments of competitive priorities in manufacturing strategies by implementing the proposed holistic analytical models are helpful in strategically managing business operations. The discussion derives the most critical attributes in business operations while alignment of resource allocation with competitive priorities help to strategically focus those attributes. In conclusion, we argue that resource allocation and manufacturing strategies have become the most important capabilities in a business environment where companies focus to get a sustainable competitive advantage.

2010-12-15

An indirect evaporative chiller is a device used to produce chilled water at a temperature between the wet bulb temperature and dew point of the outdoor air, which can be used in building HVAC systems. This article presents a theoretical analysis and practical performance of an innovative indirect evaporative chiller. First, the process of the indirect evaporative chiller is introduced; then, the matching characteristics of the process are presented and analyzed. It can be shown that the process that produces cold water by using dry air is a nearly-reversible process, so the ideal produced chilled water temperature of the indirect evaporative chiller can be set close to the dew point temperature of the chiller's inlet air. After the indirect evaporative chiller was designed, simulations were done to analyze the output water temperature, the cooling efficiency relative to the inlet dew point temperature, and the COP that the chiller can performance. The first installation of the indirect evaporative chiller of this kind has been run for 5 years in a building in the city of Shihezi. The tested output water temperature of the chiller is around 14-20 C, which is just in between of the outdoor wet bulb temperature and dew point. The tested COP{sub r,s} of the developed indirect evaporative chiller reaches 9.1. Compared with ordinary air conditioning systems, the indirect evaporative chiller can save more than 40% in energy consumption due to the fact that the only energy consumed is from pumps and fans. An added bonus is that the indirect evaporative chiller uses no CFCs that pollute to the aerosphere. The tested internal parameters, such as the water-air flow rate ratio and heat transfer area for each heat transfer process inside the chiller, were analyzed and compared with designed values. The tested indoor air conditions, with a room temperature of 23-27 C and relative humidity of 50-70%, proved that the developed practical indirect evaporative chiller

Competitive differentiation through brand extensions in the era of hyper competition

2015-03-01

Full Text Available In the era of hyper competition, competitive differentiation has become increasingly important. Brand extensions are used by companies across various industries for competitive differentiation. But in the era of hyper competition, a successful differentiation strategy requires that a brand emphasizes on uniqueness rather than commoditization. In this article, we make a case for creating a meaningful differentiation strategy. We emphasize the role of brand extensions for competitive differentiation and highlight the main perils of using brand extensions as a primary differentiation strategy. By using qualitative research, we identify primary objectives for brand extensions in practice. This investigation uses in-depth interviews with 14 senior brand managers across various industries to highlight brand portfolio strategies in relation to the brand differentiation strategy. Findings reveal that for business at the base of the pyramid, in markets such as Romania, brand managers are using brand extensions to increase sales or to boost short-term revenue rather than to implement a coherent differentiation strategy. We conclude with multiple recommendations for improving brand extension usage as a strategic instrument for creating meaningful differentiation in the era of hyper competition.

Indirect Consequences of Recreational Fishing in Freshwater Ecosystems: An Exploration from an Australian Perspective

Directory of Open Access Journals (Sweden)

Shelley Burgin

2017-02-01

Full Text Available Recreational fishing in freshwater ecosystems is a popular pastime in Australia. Although most native fish are endemic, the fauna is depauperate compared to any landmass of similar size. With commercial fishing no longer a major industry in the country’s freshwaters, the future sustainability of these ecosystems will depend heavily on the actions of recreational fishers. However, there has been limited focus on the consequences of recreational fishing in freshwaters. There is particularly a dearth of information on the indirect consequences of fishers on the waterbodies they depend on for their sport. After outlining the respective trends in commercial and recreational fishing in Australia as a basis for placing the sport in context, the indirect impacts of fishers on water quality, movement (walking, off-road vehicles, the introduction/translocation of fauna (particularly fish, the dispersal of flora and the transmission of fish disease and pathogens are reviewed. It is concluded that with the decline of commercial fishing, the competition between commercial fin-fishing and recreational fishing is negligible, at least throughout most of the country. It is also concluded that each of the issues addressed has the potential to be detrimental to the long-term sustainability of the freshwater ecosystems that the fishers depend on for their recreation. However, information on these issues is scant. This is despite the current and predicted popularity of freshwater recreational fishing continuing to increase in Australia. Indeed, there has been insufficient quantitative assessment of the impacts to even determine what is required to ensure a comprehensive, adequate and representative protection of these freshwater ecosystems. To underpin the sustainability of inland recreational fishing in the country, it was concluded that research is required to underpin the development and implementation of appropriate policies. The alternative is that the

Indirect detection allows one to monitor species that normally do not give a response. It has grown from an intellectual curiosity to become an extremely useful tool. For volume displacement, polarimetry gives the best results. For charge displacement, ion chromatography and capillary zone electrophoresis are ideal situations for applying indirect fluorescence detection. LOD surpasses all but the most specialized detection schemes. Future developments in systems specially designed for indirect detection should make these schemes even more powerful

Rethinking Teaching of Basic Principles of Economics from a Sustainability Perspective

Namrata Chindarkar

2018-05-01

Full Text Available In this paper, we posit that sustainability warrants explicit recognition in the teaching of basic principles of economics. The conventional exposition of conceptual and analytic frameworks in basic principles in almost all standard economics textbooks overlooks at least two basic flaws. The first of these concerns the collection of residual externalities that exist without being internalized in market transactions and hence fall outside the calculus of national income accounting. For example, not all energy resource prices capture the entirety of the damages inflicted on natural ecosystems. The cumulus of residual externalities threatens the feasibility of sustainability. The second flaw is the absence of sustainability as a necessary condition in the fundamental benchmark of perfect competition (PC. Sustainability, when explicitly introduced in the PC benchmark, results in significant changes to conceptual premises in economics. The most significant of such changes concerns the axiomatic differentiation between “goods” and “bads”.

The existence and it's manifestation is justified, because the operation of any company involves costs that must be covered by sufficient resources. Since ancient times, each state has adopted its own tax system, more or less perfected, as the state has experienced a greater or lesser economic and military power At the base of this work stays the fact that tax systems are a key factor influencing the overall efficiency of the economy. They determine the size tendency to save, invest and work, influencing the increase in production and employment, which is essential sights integral economic strategy, making tax reform an important component of economic reform. This paper aims to analyze the indirect taxes and their contribution to the public revenues in Romania, the purpose paper contains an analysis based on statistical series as indirect taxation is where tax harmonization was possible. Through analyzes, the paper aims to provide answers to the problem of the contradiction between the growing need for budgetary revenues, which entails a continuous amplification and diversification of taxation, on the one hand, and the need to stimulate economic development, on the other hand. The harmonization of indirect taxation had been achieved since this touches the free movement of goods and the freedom to supply services, not being able to say the same thing about direct taxation, which is why the European Community Treaty does not specify expressly the alignment of direct taxation, considering that direct taxation is a matter of Internal Policies that, for a country free option.

Competition in energy

With changes occurring within both the gas and electricity industries and both sectors undergoing simultaneous reforms at the State and national levels it is timely to look at some major aspects of the energy-reform processes in Australia and to attempt to offer some perspectives from the viewpoint of an industry user of energy. From an industry user's viewpoint there is quantifiable evidence that competition in the energy sector will deliver major economic benefits to industry and the nation. The reform process currently in train will increase Australia's international competitiveness. Commonwealth-State collaboration is useful on economic issues which require a national consistent approach. Many significant and complex arrangement apply to the gas and electricity sectors which add to the complexity of the respective reform processes. More competitive arrangements are therefore required more quickly at several stages of the gas-sector reform process, such as in the commercialization of government utilities, resolving the issue of third-party transmission pricing, and the removal of State governments' impediments to competitive trading. The Hilmer Report on National Competition Policy will help deal with some difficult structural and transitional issues, e.g. third-party access, competitive structures, regulatory regimes, and a consistent national approach.(author). 1 fig., 1 photo

Bao, Wulijibilige; Cui, Xin; Wang, Zhi-Ping

2015-01-01

In this study, the diffuse pattern and path of hydrogen in transition metal rhodium are investigated by the first-principles calculations. Density functional theory is used to calculate the system energies of hydrogen atom occupying different positions in rhodium crystal lattice. The results indicate that the most stable position of hydrogen atom in rhodium crystal lattice locates at the octahedral interstice, and the tetrahedral interstice is the second stable site. The activation barrier energy for the diffusion of atomic hydrogen in transition metal rhodium is quantified by determining the most favorable path, i.e., the minimum-energy pathway for diffusion, that is the indirect octahedral-tetrahedral-octahedral (O-T-O) pathway, and the activation energy is 0.8345eV

The importance of assembly processes in shaping biological communities is poorly understood, especially for microbes. Here we report on the forces that structure soil bacterial communities along a 2000 m elevational gradient. We characterized the relative importance of habitat filtering and competition on phylogenetic structure and turnover in bacterial communities. Bacterial communities exhibited a phylogenetically clustered pattern and were more clustered with increasing elevation. Biotic factors (i.e. relative abundance of dominant bacterial lineages) appeared to be most important to the degree of clustering, evidencing the role of the competitive ability of entire clades in shaping the communities. Phylogenetic turnover showed the greatest correlation to elevation. After controlling for elevation, biotic factors showed greater correlation to phylogenetic turnover than all the habitat variables (i.e. climate, soil and vegetation). Structural equation modelling also identified that elevation and soil organic matter exerted indirect effects on phylogenetic diversity and turnover by determining the dominance of microbial competitors. Our results suggest that competition among bacterial taxa induced by soil carbon contributes to the phylogenetic pattern across elevational gradient in the Tibetan Plateau. This highlights the importance of considering not only abiotic filtering but also biotic interactions in soil bacterial communities across stressful elevational gradients.

The relative importance of seed competition, resource competition and perturbations on community structure

2011-05-01

Full Text Available While the regional climate is the primary selection pressure for whether a plant strategy can survive, however, competitive interactions strongly affect the relative abundances of plant strategies within communities. Here, we investigate the relative importance of competition and perturbations on the development of vegetation community structure. To do so, we develop DIVE (Dynamics and Interactions of VEgetation, a simple general model that links plant strategies to their competitive dynamics, using growth and reproduction characteristics that emerge from climatic constraints. The model calculates population dynamics based on establishment, mortality, invasion and exclusion in the presence of different strengths of perturbations, seed and resource competition. The highest levels of diversity were found in simulations without competition as long as mortality is not too high. However, reasonable successional dynamics were only achieved when resource competition is considered. Under high levels of competition, intermediate levels of perturbations were required to obtain coexistence. Since succession and coexistence are observed in plant communities, we conclude that the DIVE model with competition and intermediate levels of perturbation represents an adequate way to model population dynamics. Because of the simplicity and generality of DIVE, it could be used to understand vegetation structure and functioning at the global scale and the response of vegetation to global change.

The liberalization of the electricity market in Austria aspects of competition and deregulation

The subject of the thesis is the deregulation of the Austrian electricity market. It starts with an introduction in the historical background of the legal basis, which until 1998 had been determined exclusively by national law. The main fields of interest in this chapter lay within the federal nature of Austrian electricity law. The next chapter deals with electricity in European Community law, it focuses on the fundamental freedoms of the Treaty on one hand and the Directive 96/92 on Common Provisions for the Electricity Markets on the other. On the basis of this introduction, the Austrian National Electricity Law (e.g. the 'Elektrizitaewirtschafts- und -organisationsgesetz 1998' and the 'Energieliberalisierungsgesetz 2000') has to be assessed. It can be shown that the transformation of Community Law has only partly been successful. Only on the basis of this national and European regulatory framework, an evaluation of the current situation is made according to the principles of competition law (e.g. horizontal agreements, abuse of market power, merger control, state aid). Either national and Community competition law is being discussed, as Community competition law also applies to competition restrictions that are caused by state action. The Austrian way of furthering renewable energies can be named as an example for an insufficient transformation. The last chapter focuses on various aspects of contract law in the deregulated market. Finally, a short summary presents the academic results of the thesis. (author)

Can competition reduce quality?

OpenAIRE

Brekke, Kurt; Siciliani, Luigi; Straume, Odd Rune

2017-01-01

In a spatial competition setting there is usually a non-negative relationship between competition and quality. In this paper we offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key assumptions, namely that the providers are motivated and risk-averse. We show that the negative relationship between competition and quality is robust to any given number of firms in the market and whether quality and price decisions are simultaneous or sequential. We...

Competition Policy in Malaysia

OpenAIRE

Lee, Cassey

2004-01-01

Malaysia does not have a national competition law. Competition is regulated at the sectoral level in the country. Two economic sectors have legal provisions for competition law but these have been relatively ineffectively enforced. The benefits of Malaysia's industrial policy as well as the policy reforms in regulation and trade have been compromised by the lack of a formal institution to address competition related issues. Hence, the future priority and direction of regulatory reform is obvi...

Full Text Available Originally developed to improve the quality and production efficiency, Lean Six Sigma is now widely adopted in other non-manufacturing sectors such as financial, trade, services, etc. The methodology known as Lean Six Sigma combines the Six Sigma techniques, ‒ which allow companies to reduce manufacturing defects ‒ and the Lean Manufacturing principles, ‒ which help companies benefit from faster processing for lower costs and with superior quality. As a result of the research, the authors observed that, despite growing popularity and impressive outcomes obtained by some companies, the Lean Six Sigma model does not always offer the expected results. However, the research has shown that the analysed company, operating in the field of courier services has managed to boost productivity and competitiveness by implementing measures that generated added value.

An Evaluation of the Self-Regulation of Promotional Competitions in South Africa

Directory of Open Access Journals (Sweden)

2016-06-01

Full Text Available Promotional competitions are competitions in which prizes are awarded by lot or chance in order to promote goods or services. In order to protect participants and consumers against abuse, these competitions are usually regulated by gambling or consumer protection legislation. However, the relevant legislation is often complemented by self-regulation, which is the focus of this contribution. Self-regulation entails the regulation or governing of an industry by the role players in that industry. This article commences by explaining the relevant terminology and exploring self-regulation in general, including the various forms of self-regulation and the binding force thereof. The nature of self-regulation is discussed together with the advantages and challenges associated with this form of regulation. This is followed by some examples of self-regulation on a global level in order to provide a comparative perspective on the topic. The provisions of the International Chamber of Commerce's Consolidated Code of Advertising and Marketing Communications Practice are summarised and the European Advertising Standards Alliance's role in self-regulation is considered. Attention is also given to the relevant industry codes in the United Kingdom in view of the comprehensive way in which promotional competitions are covered by self-regulation in that country. The main part of the article centres on the self-regulatory position in South Africa. A brief overview of the role and function of the Advertising Standards Authority of South Africa (ASASA is provided. The provisions of the ASASA's Code of Advertising Practice are then examined and some ASASA rulings are discussed in order to illustrate the relevant principles. Thereafter, the focus shifts to the Code of Conduct of the Wireless Application Service Providers' Association, which contains detailed provisions relating to promotional competitions. Some relevant rulings are also considered. In conclusion

Direct versus indirect detection of supersymmetric dark matter

Energy Technology Data Exchange (ETDEWEB)

NONE

2003-07-01

This document gathers the slides that were presented during the workshop 'direct versus indirect detection of supersymmetric dark matter'(about 30 contributions). This workshop intended to bring together people from the particle theory community, astrophysicists and cosmologists, as well as experimentalists involved in the detection of dark matter. The aim is to generate a discussion about current and future strategies for detection of SUSY dark matter (with focus, but not exclusively, on neutralinos). Complementarities between accelerator, direct and indirect searches as well as a comparison between the uncertainties in direct and indirect searches of dark matter, are supposed to be discussed. Among the issues which will be addressed are: -) the crucial questions related to the structure of galaxies (local dark matter density, clumping, anomalous velocity distributions, etc.) ; -) the possibilities offered by the present and future experimental facilities for direct and indirect (photon, neutrino) searches; -) the potential for the discovery of SUSY at LHC and beyond; and -) the parameterization of the SUSY breaking models beyond the minimal versions.
