We introduce a discrete multiplicative process as a generic model of competition. Players with different abilities successively join the game and compete for finite resources. Emergence of dominant players and evolutionary development occur as a phase transition. The competitive dynamics underlying this transition is understood from a formal analogy to statistical mechanics. The theory is applicable to bacterial competition, predicting novel population dynamics near criticality

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.

Full Text Available The modern consumer market is characterized by a complex of immanent tendencies of development, the competitive relations reflecting specifics inherent in it. These tendencies of development of the competitive environment of the consumer market are in many respects caused by a state and extent of use of competitive capacity of the organizations functioning in this market. This obvious circumstance causes the necessity of complex scientific research of competitive capacity of trade organizations, including its structures, for definition of prospects of its sustainable strategic development. Immanent properties of competitive capacity of trade organization allowed to study in detail its structure, by means of the substantial review of the existing options of its representation and their systematization on specific, element and system signs. In development of specific structure of competitive potential its addition commercial, technological, communication, consumer and image the potentials reflecting functional and branch specifics of activity of trade organization is offered. The system of elements of competitive capacity of trade organization is given by its structure-forming types. It is proved that these elements aren't characterized by strict distribution by types of potentials, and separate from elements are universal, accepted for simultaneous use when forming all types of potential. Allocation of a system sign of structurization of competitive potential was based on situation that "systemacity" has to be provided not so much with hierarchy of hierarchy of types and elements of potential, their interrelations, how many possibility of the accounting of various classification signs allowing to typify competitive potential as system integrity, regardless of its separate types. Those signs were the stage of a demand and level of use in economic activity, economic feasibility of existence of unrealized potential, the origin nature.

Multiple helix ecosystems for sustainable competitiveness
Ferreira, João; Farinha, Luís; Fernandes, Nuno
2016-01-01
This book discusses the main issues, challenges, opportunities, and trends involving the interactions between academia, industry, government and society. Specifically, it aims to explore how these interactions enhance the ways in which companies deliver products and services in order to achieve sustainable competitiveness in the marketplace. Sustainable competitiveness has been widely discussed by academics and practitioners, considering the importance of protecting the environment while sustaining the economic goals of organizations. The Quintuple Helix innovation model is a framework for facilitating knowledge, innovation and sustainable competitive advantage. It embeds the Triple and the Quadruple Helix models by adding a fifth helix, the “natural environment.” The Triple Helix model focuses on the university-industry-government triad, while the Quadruple adds civil society (the media- and culture-driven public) as a fourth helix. The Quintuple Helix model facilitates research, public policy, and pract...
Competitive market for multiple firms and economic crisis
Tao, Yong
2010-09-01
The origin of economic crises is a key problem for economics. We present a model of long-run competitive markets to show that the multiplicity of behaviors in an economic system, over a long time scale, emerge as statistical regularities (perfectly competitive markets obey Bose-Einstein statistics and purely monopolistic-competitive markets obey Boltzmann statistics) and that how interaction among firms influences the evolutionary of competitive markets. It has been widely accepted that perfect competition is most efficient. Our study shows that the perfectly competitive system, as an extreme case of competitive markets, is most efficient but not stable, and gives rise to economic crises as society reaches full employment. In the economic crisis revealed by our model, many firms condense (collapse) into the lowest supply level (zero supply, namely, bankruptcy status), in analogy to Bose-Einstein condensation. This curious phenomenon arises because perfect competition (homogeneous competitions) equals symmetric (indistinguishable) investment direction, a fact abhorred by nature. Therefore, we urge the promotion of monopolistic competition (heterogeneous competitions) rather than perfect competition. To provide early warning of economic crises, we introduce a resolving index of investment, which approaches zero in the run-up to an economic crisis. On the other hand, our model discloses, as a profound conclusion, that the technological level for a long-run social or economic system is proportional to the freedom (disorder) of this system; in other words, technology equals the entropy of system. As an application of this concept, we give a possible answer to the Needham question: “Why was it that despite the immense achievements of traditional China it had been in Europe and not in China that the scientific and industrial revolutions occurred?”

Competitive Stem Cell Recruitment by Multiple Cytotactic Cues
Mendelson, Avital; Cheung, Yukkee; Paluch, Kamila; Chen, Mo; Kong, Kimi; Tan, Jiali; Dong, Ziming; Sia, Samuel K.; Mao, Jeremy J.
2014-01-01
A multitude of cytotactic cues direct cell migration in development, cancer metastasis and wound healing. However, our understanding of cell motility remains fragmented partially because current migration devices only allow the study of independent factors. We developed a cell motility assay that allows competitive recruitment of a given cell population simultaneously by gradients of multiple cytotactic cues, observable under real-time imaging. Well-defined uniform gradients of cytotactic cues can be independently generated and sustained in each channel. As a case study, bone marrow mesenchymal stem/stromal cells (MSCs) were exposed to 15 cytokines that are commonly present in arthritis. Cytokines that induced robust recruitment of MSCs in multiple groups were selected to ‘compete’ in a final round to yield the most chemotactic factor(s) based on cell migration numbers, distances, migration indices and motility over time. The potency of a given cytokine in competition frequently differed from its individual action, substantiating the need to test multiple cytokines concurrently due to synergistic or antagonistic effects. This new device has the rare capacity to screen molecules that induce cell migration in cancer therapy, drug development and tissue regeneration. PMID:23364311
Sustainable competitive advantage for accountable care organizations.
Macfarlane, Michael Alex
2014-01-01
In the current period of health industry reform, accountable care organizations (ACOs) have emerged as a new model for the delivery of high-quality and cost-effective healthcare. However, few ACOs operate in direct competition with one another, and the accountable care business model has yet to present a means of continually developing new marginal value for patients and network partners. With value-based purchasing and patient consumerism strengthening as market forces, ACOs must build organizational sustainability and competitive advantage to meet the value demands set by customers and competitors. This essay proposes a strategy, adapted from the disciplines of agile software development and Lean product development, through which ACOs can engage internal and external customers in the development of new products that will provide sustainability and competitive advantage to the organization by decreasing waste in development, promoting specialized knowledge, and closely targeting customer value.
A Competitive Market in Human Organs

Danny Frederick
2010-11-01
Full Text Available I offer consequentialist and deontological arguments for a competitive market in human organs, from live as well as dead donors. I consider the objections that a market in organs will frustrate altruism, coerce the desperate, expose under-informed agents to unacceptable risks, exacerbate inequality, degrade those who participate in it, involve a kind of slavery, impose invidious costs, and impair third-party choice sets. I show that each of these objections is without merit and that, in consequence, the opposition to markets in organs is an untenable endorsement of death, suffering and the suppression of freedom.

Full Text Available The mechanism of the organizational competitiveness increase, which is employed to enhance the organizational structure, has been performed in the research. The principles ensuring the product competitiveness have been pointed out. The involvement of the strategic marketing service organizational structure which aims to optimize the information flows for the development of the managerial decisions has been proved. The generalized structure of strategic marketing services focused on medium-sized and large enterprises has been proposed. The proposed strategic marketing service develops strategic standards for all production parameters on the first stage of organizational product life cycle. Employing the innovation management methods, it prepares the exclusive values for all production parameters to turn them into an organizational competitiveness according to the following scheme: exclusive value, competitive advantages of products, competitiveness of products and organization competitiveness. Strategic Marketing Service together with top managers performs: the strategic vision and organization mission development, the tree of long-term objectives development, the strategy of the organization competitiveness improvement development, projects formation, control, and implementation. The Strategic Marketing Service Management is based on the strategic management functions implementation while performing the strategy of organizational competitiveness increase. The mechanism structure of the strategy of organizational competitiveness increase that will effectively perform the strategic management decisions and convert the exclusive values into the organizational competitiveness has been proposed.

2017-11-01
The influences of intra- and inter-species competition on ecosystems are poorly understood. Lemna aequinoctialis and Spirodela polyrhiza were used to assess the effects of exposure to different concentrations of multiple heavy metals (copper-cadmium-zinc), when the plants were grown in mixed- or mono-culture. Parameters assessed included relative growth rate (RGR), content of chlorophyll, glutathione (GSH), malondialdehyde (MDA), as well as the activity of catalase (CAT), superoxide dismutase (SOD) and peroxidase (POD). Inter-specific competition was affected by metal concentration, with results indicating that inter-specific competition significantly affected duckweed growth and metal uptake in different heavy metal exposure conditions. Inter-specific competition increased growth rate of duckweed under high metal concentrations, although when compared with intra-specific competition, it caused no obvious differences under low metal concentrations. The growth of L. aequinoctialis was further increased in mixed culture when exposed to high metal concentrations, with inter-specific competition increasing the content of cadmium and zinc, while decreasing copper content of L. aequinoctialis compared with under intra-specific conditions. Conversely, inter-specific competition increased the content of copper and cadmium of S. polyrhiza, without causing obvious differences in zinc accumulation under high ambient concentrations. Under high metal conditions, inter-specific competition increased antioxidant enzyme activities in duckweed species, increasing resistance to heavy metals. Results show that inter-specific competition makes duckweed develop mechanisms to increase fitness and survival, such as enhancement of antioxidant enzyme activities, rather than limiting metal uptake when exposed to high concentrations of multiple metals.

Some Consideration On Knowledge Management Implication On Organization's Competitiveness
Draghici, Anca; Ciortan, Marius Areta; Florea, Claudia
2015-07-01
The research described in this paper has been focused on two objectives: to debate the knowledge management's active role for organizations competitive advantage and to describe information technology's capabilities in leveraging the knowledge worker's competencies. For the purposes of this article, competitive advantage is perceived as a strength that provides a market advantage relative to a competitor. Often competitive advantage is related to the core competencies of the organisation, which are frequently based on implicit know-how or tacit knowledge. This intangible, unstructured knowledge is difficult to manage; consequently management has ignored it when designing business strategy. However, the increased competitive pressures of the post-industrial global economy and the exponential advances in computing power have increased management's interest in knowledge as a sustainable source of competitive advantage.

It is demonstrated that a Kolmogorov-type competition model featuring species allocation and gain functions can possess multiple coexistence statesE Two examples are constructed: one in which the two competing species possess rectangular allocation functions but distinct gain functions, and the other in which one species has a rectangular allocation function, the second species has a bi-rectangular allocation function, and the two species share a common gain function. In both examples, it is shown that the species nullclines may intersect multiple times within the interior of the first quadrant, thus creating both locally stable and unstable equilibrium points. These results have important applications in the study of plant competition for sunlight, in which the allocation functions describe the vertical placement of leaves for two competing species, and the gain functions represent rates of photosynthesis performed by leaves at different heights when shaded by overlying leaves belonging to either species.
How can natural gas markets be competitively organized

In this paper it will be discussed how to most effectively give room to competitive forces in natural gas markets, given the traditional merchant pipeline as point of departure. Alternative models of organizing the market will be reviewed: we first consider decreasing barriers to entry and then analyze advantages and drawbacks of a third party access system. In this context different forms of implementing a competitive market for transportation capacity and coordinating it with gas trade are discussed, among them a simultaneous auction of gas and transmission capacity. Finally a hub system of point markets in conjunction with third party access will be suggested to allow for competitive markets for gas and transportation service. 33 refs

"Managed competition" for Ireland? The single versus multiple payer debate.
LENUS (Irish Health Repository)
Mikkers, Misja
2014-09-01
A persistent feature of international health policy debate is whether a single-payer or multiple-payer system can offer superior performance. In Ireland, a major reform proposal is the introduction of \\'managed competition\\' based on the recent reforms in the Netherlands, which would replace many functions of Ireland\\'s public payer with a system of competing health insurers from 2016. This article debates whether Ireland meets the preconditions for effective managed competition, and whether the government should implement the reform according to its stated timeline. We support our arguments by discussing the functioning of the Dutch and Irish systems.

Full Text Available The contribution is aimed at the assessment of recommended crop management practices of chosen cereals for organic farming. To increase competitiveness, these practices are modified depending on soil and climatic conditions, and on a way of production use. Furthermore, impacts of the recommended crop management practices on economics of growing chosen cereals are evaluated and compared with economic results obtained under conventional farming. It is assumed that achieved results will contribute to the increase in proportion of arable crops in the Czech Republic where organic production offer does not meet current demands.When evaluating results of growing individual cereal species in a selective set of organic farms, triticale, spelt and spring barley (in this ranking can be considered as profitable crops. Moreover, triticale and spelt have even higher gross margin under organic farming than under conventional farming (by 62 % in triticale. Oat brings losses, however, it is important for livestock production. Winter wheat seems to be also unprofitable since less grain is produced at lower imputs per hectare and only part of it is produced in quality “bio”, i.e. marketed for higher prices. Rye also brings losses under organic farming, particularly due to lower yields, similarly to the other mentioned cereals. Special cereal species that are still neglected in organic farming systems are of potential use. Durum wheat has vitreous kernels with a high content of quality gluten which is used for pasta production. It can be grown in the maize production area on fertile soils only.
A specter of coexistence: Is centrifugal community organization haunted by the ghost of competition?
Wasserberg, Gideon; Kotler, B.P.; Morris, D.W.; Abramsky, Z.
2006-01-01
In a centrifugally organized community species prefer the same habitat (called "core") but differ in their secondary habitat preferences. The first model of centrifugal community organization (CCO) predicted that optimally foraging, symmetrically competing species would share use of the core habitat at all density combinations. But one might also assume that the competition in the core habitat is asymmetrical, that is, that one of the species (the dominant) has a behavioral advantage therein. In this study, we asked how should habitat use evolve in a centrifugally organized community if its species compete asymmetrically in the core habitat? To address this question we developed an "isoleg model". The model predicts that in a centrifugally organized community, asymmetric competition promotes the use of the core habitat exclusively by the dominant species at most points in the state space. The separation of the core habitat use by the species ("the ghost of competition past") may be either complete or partial ("partial ghost"), and behavior at the stable competitive equilibrium between the species could determine whether coexistence should occur at the "complete-" or the "partial ghost" regions. This version of CCO should be a common feature of competitive systems.

Full Text Available The purpose of this research was to establish the level of importance attached to competitive intelligence (CI at a mass import retail organization in South Africa. The rationale of CI is to alert an organization about the current situation as it relates to its business environment and competitors, and how these aspects affect the competitive situation. In this article, the value and significance that CI presents to organizations upon implementation are discussed by focusing upon the need for a competitive strategy, the significance of institutionalizing CI, various organizational structure options and the establishment of a CI culture. A survey was conducted at a mass import retail organization to determine the level of importance attached to CI. A total of 107 employees were randomly selected to participate in the completion of a questionnaire. Based on the results, it was found that this organization practised CI, albeit in an informal manner, and it was concluded that there was a relatively high level of importance attached to CI within this organization. However, areas for improvement were identified and a recommendation was made of implementing a formal CI function within the organization.

Full Text Available Abstract Background The foodborne, gram-positive pathogen, Listeria monocytogenes, is capable of causing lethal infections in compromised individuals. In the post genomic era of L. monocytogenes research, techniques are required to identify and validate genes involved in the pathogenicity and environmental biology of the organism. The aim here was to develop a widely applicable method to tag L. monocytogenes strains, with a particular emphasis on the development of multiple strain competitive index assays. Results We have constructed a new site-specific integrative vector, pIMC, based on pPL2, for the selection of L. monocytogenes from complex samples. The pIMC vector was further modified through the incorporation of IPTG inducible markers (antibiotic and phenotypic to produce a suite of four vectors which allowed the discrimination of multiple strains from a single sample. We were able to perform murine infection studies with up to four EGDe isolates within a single mouse and showed that the tags did not impact upon growth rate or virulence. The system also allowed the identification of subtle differences in virulence between strains of L. monocytogenes commonly used in laboratory studies. Conclusion This study has developed a competitive index assay that can be broadly applied to all L. monocytogenes strains. Improved statistical robustness of the data was observed, resulting in fewer mice being required for virulence assays. The competitive index assays provide a powerful method to analyse the virulence or fitness of L. monocytogenes in complex biological samples.

Strategies for Revitalizing Organizations: Regaining the Competitive Edge
Nysmith, C. Robert
1987-01-01
During the last decade, the United States has lost competitive stature in the world. Challenged daily by a technically sophisticated and vitalized global economy, industry and Government are examining quality and productivity initiatives with which to meet the foreign competitive challenge. At stake are our quality of life and our standard of living for the remainder of this century and beyond. Being competitive is an ongoing process, tuned to an awareness and understanding of the dynamics of the world marketplace and to the changing nature of the work environment. Solutions to America's quality and productivity problems do not exist independently within any organization or industry or at any given level of society. Success depends on commitment, partnership, meshing of goals and responsibilities, mutual respect and understanding, and a desire to be first. A change in organizational management culture is required. Traditional authoritarian management practices must give way to enlightened leadership initiatives that stress employee involvement and participation. There must be a lessening of adversarial relationships between management and labor and between industry and Government. Quality and productivity are understood to be the end result of an integrated process which begins with vigorous, committed leadership and ends with a satisfied customer. The essential elements in the revitalization process are organized in this report into seven strategies which represent the major findings of the Second NASA Symposium on Quality and Productivity. Each strategy is then broken down into its principal themes which are presented as recommendations. No one strategy can stand apart from any other; all are interrelated and work together.

Young men who have sex with men (YMSM) have the highest rates of human immunodeficiency virus (HIV) infection in the United States. Decades into the HIV epidemic, the relationships that YMSM-serving health and social organizations have with one another has not been studied in depth. The aim of this study was to examine the competition, collaboration, and funding source structures of multiplex organization networks and the mechanisms that promote fruitful relationships among these organizations. The study data collection method was a survey of health and social organizations from 2013-2014 in 2 cities, Chicago, IL and Houston, TX. Study participants were representatives from 138 health and social organizations. Responses to survey questions were used to reconstruct competition, collaboration, and combined competition-collaboration networks. While taking into consideration the collaborative relationships among organizations, we provide statistical evidence that organizations of similar type, similar social media use patterns, comparable patterns of funding, and similar network contexts tended to compete with one another. This competition was less likely to be accompanied by any sort of collaboration if the organizations shared common funding sources. Competition that excludes potential collaboration may be detrimental to mobilizing the collective efforts that serve local YMSM communities. System-level interventions may provide promising approaches to scaling-up HIV prevention and treatment efforts so as to encourage organizations to form partnerships with otherwise competing providers.

Research Design The study data collection method was a survey of health and social organizations from 2013–2014 in two cities, Chicago IL, and Houston TX. Subjects Study participants were representatives from 138 health and social organizations. Measures Responses to survey questions were used to reconstruct competition, collaboration and combined competition-collaboration networks. Results While taking into consideration the collaborative relationships among organizations, we provide solid statistical evidence that organizations of similar type, similar social media use patterns, comparable patterns of funding, and similar network contexts tended to compete with one another. This competition was less likely to be accompanied by any sort of collaboration if the organizations shared common funding sources. Conclusions Competition that excludes potential collaboration may be detrimental to mobilizing the collective efforts that serve local YMSM communities. System-level interventions may provide promising approaches to scaling-up HIV prevention and treatment efforts so as to encourage organizations to form partnerships with otherwise competing providers.

Scaffolded DNA origami are a robust tool for building discrete nanoscale objects at high yield. This strategy ensures, in the design process, that the desired nanostructure is the minimum free energy state for the designed set of DNA sequences. Despite aiming for the minimum free energy structure, the folding process which leads to that conformation is difficult to characterize, although it has been the subject of much research. In order to shed light on the molecular folding pathways, this study intentionally frustrates the folding process of these systems by simultaneously annealing the staple pools for multiple target or parent origami structures, forcing competition. A surprising result of these competitive, simultaneous anneals is the formation of chimeric DNA origami which inherit structural regions from both parent origami. By comparing the regions inherited from the parent origami, relative stability of substructures were compared. This allowed examination of the folding process with typical characterization techniques and materials. Anneal curves were then used as a means to rapidly generate a phase diagram of anticipated behavior as a function of staple excess and parent staple ratio. This initial study shows that competitive anneals provide an exciting way to create diverse new nanostructures and may be used to examine the relative stability of various structural motifs. (paper)

Price competition and equilibrium analysis in multiple hybrid channel supply chain
Kuang, Guihua; Wang, Aihu; Sha, Jin
2017-06-01
The amazing boom of Internet and logistics industry prompts more and more enterprises to sell commodity through multiple channels. Such market conditions make the participants of multiple hybrid channel supply chain compete each other in traditional and direct channel at the same time. This paper builds a two-echelon supply chain model with a single manufacturer and a single retailer who both can choose different channel or channel combination for their own sales, then, discusses the price competition and calculates the equilibrium price under different sales channel selection combinations. Our analysis shows that no matter the manufacturer and retailer choose same or different channel price to compete, the equilibrium price does not necessarily exist the equilibrium price in the multiple hybrid channel supply chain and wholesale price change is not always able to coordinate supply chain completely. We also present the sufficient and necessary conditions for the existence of equilibrium price and coordination wholesale price.
Physician Competition in the Era of Accountable Care Organizations.
Richards, Michael R; Smith, Catherine T; Graves, Amy J; Buntin, Melinda B; Resnick, Matthew J
2018-04-01
To calculate physician concentration levels for all U.S. markets using detailed data on integration and accountable care organization (ACO) participation. 2015 SK&A office-based physician survey linked to all commercial and public payer ACOs. We construct three separate Herfindahl-Hirschman Index (HHI) measures and plot their distributions. We then investigate how prevailing levels of concentration change when incorporating more detailed organizational features into the HHI measure. Horizontal and vertical integration strongly influences measures of physician concentration; however, ACOs have limited impact overall. ACOs are often present in competitive markets, and only in a minority of these markets do ACOs substantively increase physician concentration. Monitoring ACO effects on physician competition will likely have to proceed on a case-by-case basis. © Health Research and Educational Trust.

Accountable Care Organizations and Antitrust Enforcement: Promoting Competition and Innovation.
Feinstein, Deborah L; Kuhlmann, Patrick; Mucchetti, Peter J
2015-08-01
The antitrust laws stand to protect consumers of health care services from conduct that would raise prices, lower quality, and decrease innovation by lessening competition. Importantly, though, vigorous antitrust enforcement does not impede accountable care organizations (ACOs) and similar collaborations that advance these same goals of better and more efficient care; in fact, by fostering competitive markets, the antitrust laws encourage such initiatives. This article summarizes the legal framework that the federal antitrust agencies - the Federal Trade Commission and the Antitrust Division of the US Department of Justice - use to analyze ACOs and other collaborations among health care providers. It outlines the guidance provided by the federal antitrust agencies concerning when ACOs and other provider collaborations likely would harm competition and consumers. In addition, it reviews common antitrust issues that can arise with ACOs and provides examples of enforcement actions that have prevented health care providers from taking or continuing anticompetitive actions.

Full Text Available The article deals with the organization management based on the strategy of social responsibility implementation that supplies the conditions for a company's competitiveness development. The theoretical statements by the leading foreign researchers about the key role of social factors in an organization success and the main conditions of competitiveness such as human resources, staff competences, customers' pleasure, an organization's reputation, organizational and managing capacity, etc. The author discusses the idea of the new aim of the management paradigm is "social business" development in the economy. Despite the fact that entrepreneurship is still based on getting the economical benefit, the competitive area, the methods and the relationship between the profit and the competitiveness have changed in the post-industrial era. The change of the consuming society structure and the complication of the competitive area make us look for other sources of competitiveness, such as investments into the human resources. Such an approach to competitiveness is more and more spread among the foreign and national companies and allows to include social aspects management into the development strategy of a company. It is stated that a socially responsible company includes social goals in the production process, thus ensuring a competitive advantage in business. An important conclusion of the research is that socially responsible organizations create better conditions for the territories’ development where they provide the society with a generally higher welfare level.

Sudden multiple fractures in a patient with sarcoidosis in multiple organs.
Sada, Mitsuru; Saraya, Takeshi; Ishii, Haruyuki; Goto, Hajime
2014-04-07
A 30-year-old man who incidentally fractured his right olecranon and other multiple phalanges was admitted to our hospital. He had a 2-year history of uveitis and bilateral hilar lymphadenopathy (BHL), and pulmonary sarcoidosis was diagnosed from transbronchial lung biopsy. Right elbow arthrodesis was performed, and biopsied specimens showed non-caseating epithelioid cell granuloma, suggesting osseous sarcoidosis. He was discharged uneventfully without further treatment, but BHL had progressed with the appearance of lung parenchymal lesions 3 months later. At that time, involvement of other organs was also noted on Gallium-67 scintigraphy, showing accumulations in BHL, axillary and inguinal lymph nodes, enlarged liver and spleen and subcutaneous areas. After initiation of steroid therapy, multiple organ involvement improved, and no further bone involvement has been recognised to date. Osseous sarcoidosis complicated by bone fracture is an extremely rare presentation, but should be considered in patients with sarcoidosis, especially when multiple organs are involved.
Competitive STDP Learning of Overlapping Spatial Patterns.
Krunglevicius, Dalius
2015-08-01
Spike-timing-dependent plasticity (STDP) is a set of Hebbian learning rules firmly based on biological evidence. It has been demonstrated that one of the STDP learning rules is suited for learning spatiotemporal patterns. When multiple neurons are organized in a simple competitive spiking neural network, this network is capable of learning multiple distinct patterns. If patterns overlap significantly (i.e., patterns are mutually inclusive), however, competition would not preclude trained neuron's responding to a new pattern and adjusting synaptic weights accordingly. This letter presents a simple neural network that combines vertical inhibition and Euclidean distance-dependent synaptic strength factor. This approach helps to solve the problem of pattern size-dependent parameter optimality and significantly reduces the probability of a neuron's forgetting an already learned pattern. For demonstration purposes, the network was trained for the first ten letters of the Braille alphabet.
Competitive advantage for multiple-memory strategies in an artificial market
Mitman, Kurt E.; Choe, Sehyo C.; Johnson, Neil F.
2005-05-01
We consider a simple binary market model containing N competitive agents. The novel feature of our model is that it incorporates the tendency shown by traders to look for patterns in past price movements over multiple time scales, i.e. multiple memory-lengths. In the regime where these memory-lengths are all small, the average winnings per agent exceed those obtained for either (1) a pure population where all agents have equal memory-length, or (2) a mixed population comprising sub-populations of equal-memory agents with each sub-population having a different memory-length. Agents who consistently play strategies of a given memory-length, are found to win more on average -- switching between strategies with different memory lengths incurs an effective penalty, while switching between strategies of equal memory does not. Agents employing short-memory strategies can outperform agents using long-memory strategies, even in the regime where an equal-memory system would have favored the use of long-memory strategies. Using the many-body 'Crowd-Anticrowd' theory, we obtain analytic expressions which are in good agreement with the observed numerical results. In the context of financial markets, our results suggest that multiple-memory agents have a better chance of identifying price patterns of unknown length and hence will typically have higher winnings.

While the European Union has put a lot of emphasis on cluster development due to their inherent advantages such as lower transaction costs, technological transfer and regional development, little is known about how clusters emerge and what can facilitate their competitiveness. This paper aims to study the impact of public-private cooperation between universities and organizations on cluster development and competitiveness. A literature review is employed to develop the model while 4 qualitative case studies provide the initial test of its validity. The analysis suggests that cooperating with research institutions impacts cluster development first through education of industrial staff, but also by developing innovation processes through the facilitation of the appearance of innovative ideas and also of knowledge sharing among organizations. The research has several implications both for organizations and for government officials. First of all, R&D and top management should actively seek to cooperate with research institutions both for training of their staff but also in seeking new ideas and as a way of collaborating with other organizations within the field without fear of losing competitive advantage. Second, government officials should try to create more incentives both for organizations (through for example tax returns) and for universities (extra funding or salary incentives) that can increase collaboration between these actors. This paper is the first one to asses empirically how cooperation with research institutions affect cluster competitiveness and development, especially within the developing region of Eastern Europe, Romania.
Optimal Service Capacities in a Competitive Multiple-Server Queueing Environment
Ching, Wai-Ki; Choi, Sin-Man; Huang, Min
The study of economic behavior of service providers in a competition environment is an important and interesting research issue. A two-server queueing model has been proposed in Kalai et al. [11] for this purpose. Their model aims at studying the role and impact of service capacity in capturing larger market share so as to maximize the long-run expected profit. They formulate the problem as a two-person strategic game and analyze the equilibrium solutions. The main aim of this paper is to extend the results of the two-server queueing model in [11] to the case of multiple servers. We will only focus on the case when the queueing system is stable.

Full Text Available Purpose: The purpose of this paper is to devise an innovative feasible, replicable and comprehensive assessment framework of a learning organization's competitive positioning. Design/methodology/approach: The three characteristics listed above are approached as follows. Feasible refers to being easy and not in need of much resources (time, personnel,.... This is done through early elimination of non-important variables. Replicable is having a well structured methodology based on scientific proven methods. Following this methodology would result in good results that can be explained if needed and replicated if deemed necessary. Comprehensive translates into a holistic set of indices that measure performance as well as organizational learning. Findings and Originality/value: The three attributes (feasible, replicable and comprehensive have become crucial for ensuring any kind of added value for such a methodology that hopes to tackle the modern dynamic business environment and gaining a sustainable competitive advantage. Research limitations/implications: Such a methodology would require several full contextual applications to be able to set its final design. It entails thorough internal revision of a company's structure. Therefore a great deal of transparency and self-transcendence from the individual involved is a pre-requisite for any chance of success. Originality/value: It offers a systematic way to assess a company's performance/competitive positioning while accounting for the crucial attribute of organizational learning in its makeup.

Full Text Available All marketers tend to position their company and its products and/or services in the market the best they could. In this context, they must develop and implement in practice a complete marketing strategy, which is undoubtedly based on three concepts: segmentation, targeting and positioning. If marketers want to successfully separate the image of their company and its brand in the minds of potential customers and users in business market it is necessary to obtain and analyze a sufficient number of accurate and relevant information from the environment. Although pieces of information about customers, suppliers and other participants in the marketing channel are significant, latterly information about competition are more important. Without a thorough and continuous research and monitoring of competition, marketers could not provide management of the company with relevant information about competing organizations, which would result in an absolutely negative impact on the quality of future management decisions. In this context, the subject of this paper is theoretical analysis of competition, and the aim of the research is to assess the real attitudes of managers in the Serbian market of styrofoam and styrodur, about the most relevant characteristics of the competition - which have a strong impact on organization's operations.

Full Text Available The interest in the conceptual delimitation of the competitiveness of cultural organizations, as well as in identifying the sources of its growth, has increased in recent years due to the need to diversify the funding sources of this type of organization, urban development and the willingness to adapt to the requirements of customers who are more numerous and have diverse expectations. Practice shows that cultural organizations that have adopted a competitive economy vision and have applied specific management tools for increasing the organizational competitiveness, have achieved a good performance, becoming, this way, an example of managerial success story in the field. The experience of Prado Museum, one of the emblems of Madrid, falls in this direction. The substantial increase in the number of tourists, the decrease in state funding combined with the increase of proprietary financing resources, the enhancement of the national and international reputation, are just some of the positive results that prove the quality of used management. This paper presents and analysis these effects and the causes that have generated them, thus providing some possible suggestions for action for Romanian cultural organizations in order to increase their competitiveness.

The paper considers the phenomena of competition in multiplex network whose structure evolves corresponding to dynamics of it's elements, forming closed loop of self-learning with the aim to reach the optimal topology. Numerical analysis of proposed model shows that it is possible to obtain scale-invariant structures for corresponding parameters as well as the structures with homogeneous distribution of connections in the layers. Revealed phenomena emerges as the consequence of the self-organization processes related to structure-dynamical selflearning based on homeostasis and homophily, as well as the result of the competition between the network's layers for optimal topology. It was shown that in the mode of partial and cluster synchronization the network reaches scale-free topology of complex nature that is different from layer to layer. However, in the mode of global synchronization the homogeneous topologies on all layer of the network are observed. This phenomenon is tightly connected with the competitive processes that represent themselves as the natural mechanism of reaching the optimal topology of the links in variety of real-world systems.

Recent research on the rate limiting steps in soil nitrogen (N) availability have shifted in focus from mineralization to soil organic matter (SOM) depolymerization. To that end, Schimel and Bennett (2004) argued that together with enzymatic breakdown of polymers to monomers, microsite processes and plant-microbial competition collectively drive N cycling. Here we present new conceptual models arguing that while depolymerization is a critical first step, mineral-organic associations may ultimately regulate the provisioning of bioavailable organic N, especially in the rhizosphere. Mineral-associated organic matter (MAOM) is a rich reservoir for N in soils and often holds 5-7x more N than particulate or labile fractions. However, MAOM is considered largely unavailable to plants as a source of N due to the physicochemical forces on mineral surfaces that stabilize organic matter. We argue that in rhizosphere hotspots, MAOM is in fact a potentially mineralizable and important source of nitrogen for plants. Several biochemical strategies enable plants and microbes to compete with mineral-organic interactions and effectively access MAOM. In particular, root-deposited low molecular weight compounds in the form of root exudates facilitate the biotic and abiotic destabilization and subsequent bioavailability of MAOM. We believe that the competitive balance between the potential fates of assimilable organic N — bound to mineral surfaces or dissolved and available for assimilation — depends on the specific interaction between and properties of the clay, soil solution, mineral-bound organic matter, and microbial community. For this reason, the plant-soil-MAOM interplay is enhanced in rhizosphere hotspots relative to non-rhizosphere environments, and likely strongly regulates plant-microbe competition for N. If these hypotheses are true, we need to reconsider potential soil N cycle responses to changes in climate and land use intensity, focusing on the processes by which
An explorative study of municipal developer competitions in Helsinki

Full Text Available This paper discusses the central features of so-called ‘site allocation competitions’, as organized by the City of Helsinki Real Estate Department (Kiinteistövirasto in Finnish. Site allocation competitions are developer competitions where the municipality sells or leases plots of land to developers or contractors, but where the ‘bidding’ is based on competing on the basis of architectural and urban quality factors. The focus in this paper is on the Finnish context, but as its legal framework is constituted by European competition law. In these competitions the proprietor expects the contractor or developer to create a design team and in turn the proprietor receives multiple proposals for a site without really paying for them. It seems important to examine this rather new type of architectural competition, as it is often an integral part of important large projects in terms of both financial investments and architectural design. It also constitutes a new tool in the practices of urban planning. The present study is explorative, based mainly on a close study and analysis of written material, such as reports, as well as three interviews with experienced organizers. The aim of the paper is to clarify the concept of developer competition, and discuss its possible benefits and problems. The core issue in the study is how architectural quality is produced within the legal framework, as well as to discuss the relation of the developer competition to the aims of urban planning and professional agents.

back to 1967, when the first Olympiad was organized in Warsaw, Poland. Today this Olympiad is a worldwide enterprise, and in the 2008 competition in Hanoi, Vietnam, students from 82 countries took part. An overview of the problems and a summary of the results of this Olympiad are given in the first paper, prepared by the organizers of the competition [3]. The students work on four or five different problems, three theoretical ones on one day, and one or two experimental tasks on another. On each day, they have five hours to accomplish their tasks. The problems are prepared by the local organizer, usually a team of physicists from universities in the home country. The level is set by an international syllabus, and the content and wording of the problems have to be agreed by a majority of the supervisors (one from each participating country) in an initial meeting. Afterwards the tasks are translated into the various languages of the competitors; the students also write their results in their own language. The number of awards (gold, silver and bronze, as well as honorable mentions) varies from competition to competition, since it depends on the number of participants. A team consists of at most five students, but they do not act as a team—they work independantly. The selection process in individual countries varies, but is usually executed in several steps, starting from school competitions and going on to regional and national ones. Training courses are often organized on the same levels. Big differences can be seen in training courses at the highest level, the duration ranging from one week to several months. The International Young Physicists Tournament (IYPT) is completely different in spirit [4]. Whereas the students work individually in the Olympiad, IYPT is a competition between teams. In addition, the 17 tasks are known almost a year in advance. The problems are very open, allow for different approaches and include experimental as well as theoretical work. The

The article describes the model construction of self-organizing competition artificial neural network, its principle and automatic recognition process of borehole lithology in detail, and then proves the efficiency of the neural network model for automatically recognizing the borehole lithology with some cases. The self-organizing competition artificial neural network has the ability of self- organization, self-adjustment and high permitting errors. Compared with the BP algorithm, it takes less calculation quantity and more rapidly converges. Furthermore, it can automatically confirm the category without the known sample information. Trial results based on contrasting the identification results of the borehole lithology with geological documentations, indicate that self-organizing artificial neural network can be well applied to automatically performing the category of borehole lithology, during the logging data explanation of sandstone-hosted uranium deposits.

Full Text Available Both competitive rivalry and internal communication play a crucial role for a business to position itself in a favourable manner in order to succeed particularly in a hostile environment. While numerous studies present the importance of competitive rivalry and of communication, even internal communication separately, little is known about the specific linkage of how competitive rivalry affects communication in the literature. Within the framework of internal communication, this study focuses on the notion that competitive rivalry is related to the path and style of communication as well as to the usage of internal communication tools but not to quality of communication. Thus, our research presents the linkage and the interaction between competitive rivalry and internal communication, of which the results indicate that, overall, competitive rivalry has a significant direct positive influence on internal communication dimensions in terms of path, style and quality of communication, as well as usage of communication tools in healthcare organizations.

We aimed to describe the pattern of solid organ injuries (SOIs) and analyze the characteristics, management and outcomes based on the multiplicity of SOIs. A retrospective study in a Level 1 trauma center was conducted and included patients admitted with blunt abdominal trauma between 2011 and 2014. Data were analyzed and compared for patients with single versus multiple SOIs. A total of 504 patients with SOIs were identified with a mean age of 28 ± 13 years. The most frequently injured organ was liver (45%) followed by spleen (30%) and kidney (18%). One-fifth of patients had multiple SOIs, of that 87% had two injured organs. Patients with multiple SOIs had higher frequency of head injury and injury severity scores (p hepatic injuries (13%) than the other SOIs. SOIs represent one-tenth of trauma admissions in Qatar. Although liver was the most frequently injured organ, the rate of mortality was higher in pancreatic injury. Patients with multiple SOIs had higher morbidity which required frequent operative management. Further prospective studies are needed to develop management algorithm based on the multiplicity of SOIs.

Colonization of the light-emitting organ of the Hawaiian squid Euprymna scolopes is initiated when the nascent organ of a newly hatched squid becomes inoculated with Vibrio fischeri cells present in the ambient seawater. Although they are induced for luminescence in the light organ, these symbiotic strains are characteristically non-visibly luminous (NVL) when grown in laboratory culture. The more typical visibly luminous (VL) type of V. fischeri co-occurs in Hawaiian seawater with these NVL strains; thus, two phenotypically distinct groups of this species potentially have access to the symbiotic niche, yet only the NVL ones are found there. In laboratory inoculation experiments, VL strains, when presented in pure culture, showed the same capability for colonizing the light organ as NVL strains. However, in experiments with mixed cultures composed of both VL and NVL strains, the VL ones were unable to compete with the NVL ones and did not persist within the light organ as the symbiosis became established. In addition, NVL strains entered light organs that had already been colonized by VL strains and displaced them. The mechanism underlying the symbiotic competitiveness exhibited by NVL strains remains unknown; however, it does not appear to be due to a higher potential for siderophore activity. While a difference in luminescence phenotype between VL and NVL strains in culture is not likely to be significant in the symbiosis, it has helped identify two distinct groups of V. fischeri that express different colonization capabilities in the squid light organ. This competitive difference provides a useful indication of important traits in light organ colonization.

Full Text Available Currently, the development of any sector involves respecting the principles of sustainability, which means economic, social and environmental development. Moreover, organic farming is a very important field for ensuring sustainable development. Romania has great potential for the development of organic agriculture, especially due to the large number of available farmland and reduced use of fertilizers and other chemicals. However, the development of organic farming in Romania is in an early stage, due to the numerous problems that Romanian agriculture is still facing. Concern for the environment should be reflected at the level of production processes and consumption. As market demand influences and stimulates production, we can ask the question to what extent stimulating the consumption of organic products through green marketing can boost organic agriculture development and competitiveness of Romanian farms. Using several methods of research, such as analysis, synthesis, comparison, statistical methods and by calling on studies, reports and data series on organic farming in the EU and Romania, this paper highlights Romania's position in terms of the level of development of organic agriculture and recommends several ways to improve the outcomes obtained by Romania in the field. Moreover, based on regression equations, the trend of convergence of Romanian organic agriculture development in relation to the EU countries is analysed. The paper demonstrates that one of the measures that can be taken by Romanian farms is green marketing strategy development that can stimulate both consumption and production of organic products. Therefore, with increasing interest in the development of organic agriculture in Romania, green marketing can play an increasingly important role in promoting the benefits of consuming organic products, thus contributing to business development of organic products as well as to the development of Romanian agriculture

The impact of HMO competition on private health insurance premiums, 1985-1992.
Wickizer, T M; Feldstein, P J
1995-01-01
A critical unresolved health policy question is whether competition stimulated by managed care organizations can slow the rate of growth in health care expenditures. We analyzed the competitive effects of health maintenance organizations (HMOs) on the growth in fee-for-service indemnity insurance premiums over the period 1985-1992 using premium data on 95 groups that had policies with a single, large, private insurance carrier. We used multiple regressions to estimate the effect of HMO market penetration on insurance premium growth rates. HMO penetration had a statistically significant (p market whose HMO penetration rate increased by 25% (e.g., from 10% to 12.5%), the real rate of growth in premiums would be approximately 5.9% instead of 7.0%. Our findings indicate that competitive strategies, relying on managed care, have significant potential to reduce health insurance premium growth rates, thereby resulting in substantial cost savings over time.

Full Text Available Many organizations in the world realize that to maintain the stability of an organization within a lot of turnover in human resources, Knowledge Management (KM is a matter that cannot be forgotten. Since by storing the knowledge, organizations can continue to distribute the knowledge to people and to develop it into a practice of learning, problem solving, and then at the end it becomes a “Best Practice”. Sharing knowledge becomes the main reference in KM in large and small organizations. By multiplying the activities of knowledge sharing among employees in an organization, it can improve the competitiveness of the organization. All activities in knowledge sharing will be easier if it is formed in a Community of Practice (CoP. CoP can be regarded as a best method. In addition there are many benefits that can be spawned by it, such as in the development, dissemination of knowledge to the development of culture in an organization. The method in this paper uses literature study by describing best practices and case studies in a private bank in Indonesia. By forming the CoP, it is expected to motivate employees to share knowledge for the improvement of organizational performance.Keywords: organization, knowledge management, community of practice

To examine market competition and facility characteristics that can be related to technical efficiency in the production of multiple dialysis outputs from the perspective of the industrial organization model. Freestanding dialysis facilities that operated in 1997 submitted cost report fonns to the Health Care Financing Administration (HCFA), and offered all three outputs--outpatient dialysis, dialysis training, and home program dialysis. The Independent Renal Facility Cost Report Data file (IRFCRD) from HCFA was utilized to obtain information on output and input variables and market and facility features for 791 multiple-output facilities. Information regarding population characteristics was obtained from the Area Resources File. Cross-sectional data for the year 1997 were utilized to obtain facility-specific technical efficiency scores estimated through Data Envelopment Analysis (DEA). A binary variable of efficiency status was then regressed against its market and facility characteristics and control factors in a multivariate logistic regression analysis. The majority of the facilities in the sample are functioning technically inefficiently. Neither the intensity of market competition nor a policy of dialyzer reuse has a significant effect on the facilities' efficiency. Technical efficiency is significantly associated, however, with type of ownership, with the interaction between the market concentration of for-profits and ownership type, and with affiliations with chains of different sizes. Nonprofit and government-owned Facilities are more likely than their for-profit counterparts to become inefficient producers of renal dialysis outputs. On the other hand, that relationship between ownership form and efficiency is reversed as the market concentration of for-profits in a given market increases. Facilities that are members of large chains are more likely to be technically inefficient. Facilities do not appear to benefit from joint production of a variety of

Lotka-Volterra competition models for sessile organisms.
Spencer, Matthew; Tanner, Jason E
2008-04-01
Markov models are widely used to describe the dynamics of communities of sessile organisms, because they are easily fitted to field data and provide a rich set of analytical tools. In typical ecological applications, at any point in time, each point in space is in one of a finite set of states (e.g., species, empty space). The models aim to describe the probabilities of transitions between states. In most Markov models for communities, these transition probabilities are assumed to be independent of state abundances. This assumption is often suspected to be false and is rarely justified explicitly. Here, we start with simple assumptions about the interactions among sessile organisms and derive a model in which transition probabilities depend on the abundance of destination states. This model is formulated in continuous time and is equivalent to a Lotka-Volterra competition model. We fit this model and a variety of alternatives in which transition probabilities do not depend on state abundances to a long-term coral reef data set. The Lotka-Volterra model describes the data much better than all models we consider other than a saturated model (a model with a separate parameter for each transition at each time interval, which by definition fits the data perfectly). Our approach provides a basis for further development of stochastic models of sessile communities, and many of the methods we use are relevant to other types of community. We discuss possible extensions to spatially explicit models.
Multiple meanings of "gift" and its value for organ donation.
Shaw, Rhonda M; Webb, Robert
2015-05-01
The "gift of life" metaphor is used to promote organ donation where commercialization is prohibited. In this article, we explore how multiple parties involved in organ transfer procedures think of gift terminology by drawing on interview data with transplantation specialists, organ transplant recipients, living directed donors and living nondirected donors. The interviews took place across New Zealand between October 2008 and May 2012, in participants' homes and hospital workplaces. The interviews were transcribed verbatim, coded manually, and thematically analyzed. Although gift language is often viewed as clear-cut, the gift trope has multiple meanings for different constituent and cultural groups, ranging from positive descriptors to obscuring and romanticizing the complexities of transplantation processes. To account for these multiple perspectives, we suggest new ethical models to capture the nuanced phenomenon of organ transfer in ways that recognize the full range of donation and reception experiences. © The Author(s) 2014.

Full Text Available Man's interest in knowing and transform his reality, has led to a continuous and incessant development of science and the production of knowledge inherent in them. This cyclical and systemic process has become itself abundance of knowledge that is daily creating and disseminating, surpassing even the physical spaces where it can be stored and beyond assimilation, use and transfer. The complex and changing knowledge in the activities of oil organizations undoubtedly demands designing strategies that transform and create new experiences, knowledge and skills, in order to innovate traditional management processes, information technology and communication, the intellectual capital and organizational culture. This paper aims to highlight the importance of Knowledge Management (KM when the enthusiasm and ability to learn intangible capital of an organization is involved to generate knowledge to make intelligent decisions. As argue Argyris and Schön (1978 Nonaka (1991 Kogut and Zander (1992 "knowledge is one of the most critical variables to achieve sustainable success in any organization." In addition to highlighting the success of organizations and the economy of the country depend on its ability to produce, assimilate, to use and transmit knowledge, to transform it into a competitive advantage.

Competitive bidding in Medicare: who benefits from competition?
Song, Zirui; Landrum, Mary Beth; Chernew, Michael E
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.
Competition between multiple words for a referent in cross-situational word learning
Benitez, Viridiana L.; Yurovsky, Daniel; Smith, Linda B.
2016-01-01
Three experiments investigated competition between word-object pairings in a cross-situational word-learning paradigm. Adults were presented with One-Word pairings, where a single word labeled a single object, and Two-Word pairings, where two words labeled a single object. In addition to measuring learning of these two pairing types, we measured competition between words that refer to the same object. When the word-object co-occurrences were presented intermixed in training (Experiment 1), we found evidence for direct competition between words that label the same referent. Separating the two words for an object in time eliminated any evidence for this competition (Experiment 2). Experiment 3 demonstrated that adding a linguistic cue to the second label for a referent led to different competition effects between adults who self-reported different language learning histories, suggesting both distinctiveness and language learning history affect competition. Finally, in all experiments, competition effects were unrelated to participants’ explicit judgments of learning, suggesting that competition reflects the operating characteristics of implicit learning processes. Together, these results demonstrate that the role of competition between overlapping associations in statistical word-referent learning depends on time, the distinctiveness of word-object pairings, and language learning history.

Competitiveness is important characteristics of each business organization (firm, company, corporation etc). It is of great significance for the organization existence and defines evaluation criteria of business success at microeconomical level. Each criterium comprises set of indicators with specific weight coefficients. In the work an ontology-based model of firm competitiveness is presented as a set of several mutually connected ontologies. It would be useful for knowledge structuring, standardization and sharing among experts and software engineers who develop application in the domain. Then the assessment of the competitiveness of various business organizations could be generated more effectively.

Highlights: → Native and protonated macroalga S. muticum are good materials for mercury removal. → Fast kinetic process and high mercury uptakes have been found for those materials. → Diffusion control is the rate limiting step of the process. → Competition effects by organic compounds, inorganic salts and divalent cations were analyzed. → Continuous flow experiments allowed identification of mercury reduction during metal removal. - Abstract: Biosorption processes constitute an effective technique for mercury elimination. Sorption properties of native and acid-treated Sargassum muticum have been studied. Effect of pH, initial mercury concentration and contact time studies provided fundamental information about the sorption process. This information was used as the reference values to analyse mercury sorption under competition conditions. Saline effect has shown little influence in sorption, when only electrostatic modifications took place upon salt addition. On the contrary, if mercury speciation dramatically changed owing to the addition of an electrolyte, such as in the case of chloride salt, very large modifications in mercury sorption were observed. Competition with other divalent cations or organic compounds has shown little or none effect on mercury, indicating that a different mechanism is taking place during the removal of these pollutants. Finally, continuous flow experiments have clearly shown that a reduction process is also taking place during mercury removal. This fact is not obvious to elucidate under batch sorption experiments. Scanning Electron Microscopy analysis of the surface of the materials show deposits of mercury(I) and metallic mercury which is indicative of the reduction process proposed.

This is the Fourth Annual Meeting of the Society for Gastrointestinal Intervention, a multi-disciplinary group of practitioners committed to a minimally invasive approach to both the diagnosis and treatment of digestive disorders. The key concepts are minimally invasive and multi-disciplinary which can be construed as practicing in parallel with occasional lines of procedural and clinical interaction or inter-disciplinary in which patients are acutely cared for by a team, with treatments tailored to the patient and not the discipline that touches the patient first. In reality, many of us exist in both worlds. Most universities and large clinics are structured in departments along traditional training lines. As such, Interventional Radiology is housed in the Radiology Department, Laparoscopic Surgery (and potentially NOTES), as a component of the General Surgery Division, and Therapeutic Endoscopy usually resides within a gastroenterology structural framework. These divisions have historically been kept separate by multiple forces: salaries and budgets usually reside in a larger division. As a group, the amount of practice devoted to GI disorders is variable (for instance, minimally invasive surgeons may approach the adrenal glands or lung lesions in some institutions and interventional radiologists often sample tissue in multiple areas outside the GI tract, and by virtue of access to the vascular tree, can stent, embolize, or TPA almost any area of the body), as well as inherent differences in our individual abilities to access organs. I have already mentioned that angiographic capabilities allow the interventional radiologist access to virtually every GI organ and those capabilities allow therapeutic options for bleeding, tumor embolization, stenting of stenotic lesions, and formation of intravascular shunts. As such, there is very limited interdisciplinary competition here although capsule endoscopy as well as double and single balloon enteroscopy have improved

Full Text Available One of the most important conditions of the existence of every organization, every enterprise is to insure the long-term sustainable development, one of the conditions of which is the increase of an organizational competitiveness. In modern economic conditions, social aspects of competitiveness are now in the foreground of interest, because just the strategy of social responsibility (SSR of modern enterprises can assure some commercial benefits, in responding, at the same time, to the social demands and in creating its well-being. Such an approach is in the basis of the notion of competitiveness. Along with «rigid parameters», such as price characteristics, the capability to deal with competitors, effective financial and production policies, «flexible factors» of competitiveness are of a big importance: a personnel potential, individual and collective competencies, organizational and managerial capabilities. As a result, we have formulated a research hypothesis: the organizational competitiveness is defined by individual and collective competencies of an organization, is based on socially responsible actions, confirms the demand for the object and insures its sustainable long-term development. Any organization should base all its actions aimed to increase its competitiveness on its intellectual potential, or on the management of individual and collective competencies that assure the sustainable development and the goal achievement. For every organizational strategic action, an effective combination of these competencies exists. So, we suggest a new definition of competitiveness: it is a social and economic category of understanding of the social responsibility, having as a central element individual and collective competencies, based on socially responsible actions of an enterprise, insuring its long-term sustainable development.

The liberalization of the electricity and gas sectors, as triggered by the European Community right, has generated deep juridical mutations. These mutations are, first, linked with market organization. In front of the diversity of the national organizations in both sectors, the European Community right could not impose a unique model of liberalization. It has established a set of common rules and principles to the different member states with the aim of ensuring the development of a competitive market. The introduction of competition gives access to the different activities of these sectors to the newcomers. However, because of their characteristics, competition cannot apply uniformly to the overall activities in concern. Two logics, one of natural monopoly, and the other of competition, will thus cohabit together. Moreover, the introduction of competition is managed. This management is characterized by the search for a new equilibrium between competition and general interest imperatives and by the creation of a new regulation authority at the institutional level. These mutations are also linked with market operation. Liberalization leads to a multiplication and an increase of the complexity of the contractual relations between the operators, the control of which is fundamental to ensure a good market operation. This mutation of operations is followed by a mutation of operators. Those are submitted to a dissociation trend of their activities in order to prevent discriminations and to fight against cross subventions. On the other hand, the operators' mutation shows a huge recombination movement which is characterized by a multiplication of concentration operations, leading to a remodeling of the market structure.

Full Text Available In this paper, the level of conceptual understanding of chemical contents among seventh grade students who participated in the municipal Chemistry competition in Novi Sad, Serbia, in 2013 have been examined. Tests for the municipal chemistry competition were used as a measuring instrument, wherein only multiple choice tasks were considered and analyzed. Determination of the level of conceptual understanding of the tested chemical contents was based on the calculation of the frequency of choosing the correct answers. Thereby, identification of areas of satisfactory conceptual understanding, areas of roughly adequate performance, areas of inadequate performance, and areas of quite inadequate performance have been conducted. On the other hand, the analysis of misconceptions was based on the analysis of distractors. The results showed that satisfactory level of conceptual understanding and roughly adequate performance characterize majority of contents, which was expected since only the best students who took part in the contest were surveyed. However, this analysis identified a large number of misunderstandings, as well. In most of the cases, these misconceptions were related to the inability to distinguish elements, compounds, homogeneous and heterogeneous mixtures. Besides, it is shown that students are not familiar with crystal structure of the diamond, and with metric prefixes. The obtained results indicate insufficient visualization of the submicroscopic level in school textbooks, the imprecise use of chemical language by teachers and imprecise use of language in chemistry textbooks.
Circulating Extracellular Histones Are Clinically Relevant Mediators of Multiple Organ Injury.

Extracellular histones are a damage-associated molecular pattern (DAMP) involved in the pathogenesis of various diseases. The mechanisms of histone-mediated injury in certain organs have been extensively studied, but an understanding of the pathophysiological role of histone-mediated injury in multiple organ injury remains elusive. To elucidate this role, we systemically subjected C57BL/6 mice to various doses of histones and performed a chronological evaluation of the morphological and functional changes in the lungs, liver, and kidneys. Notably, histone administration ultimately led to death after a dose-dependent aggravation of multiple organ injury. In chronological studies, pulmonary and hepatic injuries occurred within 15 minutes, whereas renal injuries presented at a later phase, suggesting that susceptibility to extracellular histones varies among organs. Histones bound to pulmonary and hepatic endothelial cells immediately after administration, leading to endothelial damage, which could be ameliorated by pretreatment with heparin. Furthermore, release of another DAMP, high-mobility group protein box 1, followed the histone-induced tissue damage, and an antibody against the molecule ameliorated hepatic and renal failure in a late phase. These findings indicate that extracellular histones induce multiple organ injury in two progressive stages-direct injury to endothelial cells and the subsequent release of other DAMPs-and that combination therapies against extracellular histones and high-mobility group protein box 1 may be a promising strategy for treating multiple organ injury.

Full Text Available The highly porous nature of metal-organic frameworks (MOFs offers great potential for the delivery of therapeutic agents. Here, we show that highly porous metal-organic frameworks can be used to deliver multiple therapeutic agents—a biologically active gas, an antibiotic drug molecule, and an active metal ion—simultaneously but at different rates. The possibilities offered by delivery of multiple agents with different mechanisms of action and, in particular, variable timescales may allow new therapy approaches. Here, we show that the loaded MOFs are highly active against various strains of bacteria.

Full Text Available The concurrent presentation of multiple stimuli in the visual field may trigger mutually suppressive interactions throughout the ventral visual stream. While several studies have been performed on sensory competition effects among non-face stimuli relatively little is known about the interactions in the human brain for multiple face stimuli. In the present study we analyzed the neuronal basis of sensory competition in an event-related functional magnetic resonance imaging (fMRI study using multiple face stimuli. We varied the ratio of faces and phase-noise images within a composite display with a constant number of peripheral stimuli, thereby manipulating the competitive interactions between faces. For contralaterally presented stimuli we observed strong competition effects in the fusiform face area (FFA bilaterally and in the right lateral occipital area (LOC, but not in the occipital face area (OFA, suggesting their different roles in sensory competition. When we increased the spatial distance among pairs of faces the magnitude of suppressive interactions was reduced in the FFA. Surprisingly, the magnitude of competition depended on the visual hemifield of the stimuli: ipsilateral stimulation reduced the competition effects somewhat in the right LOC while it increased them in the left LOC. This suggests a left hemifield dominance of sensory competition. Our results support the sensory competition theory in the processing of multiple faces and suggests that sensory competition occurs in several cortical areas in both cerebral hemispheres.

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.

Full Text Available Development of the competitive advantage involves a considerable effort from any organization. In particular, those organizations involved in a strong competitive market require the development of strategies to allocate long-term strategic marketing resources, efficiently and with easily quantifiable results. Faced with a multitude of phenomena and processes sometimes contradictory on different markets of consumption, contemporarily marketing has the mission to develop as creative as possible the business strategy of the organizations, their capacity of interacting with customers and other categories of audience. Such concepts as strategic positioning, relational marketing, management of the relationship with the consumer, marketing integrated research, a.s.o. are only a few of the tools with the help of which the marketing managers will implement successful operational strategies. All these developments are creating a real new paradigm of Marketing aimed to better explain the new types of complex market relationship in which the 21st Century organization is .

Picking battles wisely: plant behaviour under competition.
Novoplansky, Ariel
2009-06-01
Plants are limited in their ability to choose their neighbours, but they are able to orchestrate a wide spectrum of rational competitive behaviours that increase their prospects to prevail under various ecological settings. Through the perception of neighbours, plants are able to anticipate probable competitive interactions and modify their competitive behaviours to maximize their long-term gains. Specifically, plants can minimize competitive encounters by avoiding their neighbours; maximize their competitive effects by aggressively confronting their neighbours; or tolerate the competitive effects of their neighbours. However, the adaptive values of these non-mutually exclusive options are expected to depend strongly on the plants' evolutionary background and to change dynamically according to their past development, and relative sizes and vigour. Additionally, the magnitude of competitive responsiveness is expected to be positively correlated with the reliability of the environmental information regarding the expected competitive interactions and the expected time left for further plastic modifications. Concurrent competition over external and internal resources and morphogenetic signals may enable some plants to increase their efficiency and external competitive performance by discriminately allocating limited resources to their more promising organs at the expense of failing or less successful organs.

Full Text Available The aim of this paper is to identify to what extent the notions of organizational and regional competitiveness are similar, in order to be targeted by a comprehensive set of public policy measures. In this respect, we discuss the notions of organizations’ and regional competitiveness and find common factors of influence, namely innovation, networks and regulation. Based on these factors, we search for empirical evidences as regards the mutual impact between the competitiveness of organizations and competitiveness of regions. We present the results using the example of foreign direct investment companies, as their location decision making process is based on assessing both the competitiveness of organizations and the advantages of locations that point to the competitiveness of a location and, extended, to that of a region. While the dissonance is expressed in the differences of interpretation for the two notions, there is a consonant policy that can be employed for supporting both organizational and regional competitiveness: the cluster policy.

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.

1999-11-01
This technical publication on competitive strategies for nuclear power plants (NPPs) is part of an ongoing project on management of NPP operations in a competitive environment. The overall objective of this project is to assist the management of operating organizations and NPPs in identifying and implementing appropriate measures to remain competitive in a rapidly changing business environment. Other documents that have been written on this topic have focused on how the environment in which NPPs operate is changing. This report instead focuses on strategies and techniques that operating organization and NPP managers can use to succeed in this environment. Of particular note is ongoing OECD/NEA work to describe the environment for nuclear power in competitive electricity markets. The main objective of the OECD/NEA study is to review the impacts of increasing market competition on the nuclear power sectors in OECD Member countries. The OECD/NEA study is identifying various nuclear aspects which have to be considered in relation to the regulatory reform of the electricity sector in OECD Member States. The OECD/NEA work was co-ordinated with the development of this IAEA report; staff members from the two organizations participated in the development and review of the associated documents. Thus, the strategies and techniques identified in this report are consistent with the impacts of increasing market competition identified in the OECD/NEA study

Recent studies particularly emphasise the growing importance of soft factors, such as reputation in the development of competitive advantage. Concept of reputation is strongly connected with stakeholder theory, which stresses the importance of corporate communications for competitive advantage of firms. The paper focuses on competitive advantage and the link among strategy, reputation and corporate communications.
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)

Interactive processes link the multiple symptoms of fatigue in sport competition.

kinematic components. Longer sport events involve pacing strategies, central and peripheral fatigue contributions and elevated RPE. During match play, the work rate can decline late in a match (or tournament) and/or transiently after intense exercise bursts. Repeated sprint ability, agility and leg strength become slightly impaired. Technique outcomes, such as velocity and accuracy for throwing, passing, hitting and kicking, can deteriorate. Physical and subjective changes are both less severe in real rather than simulated sport activities. Little objective evidence exists to support exercise-induced mental lapses during sport. A model depicting mind-body interactions during sport competition shows that the RPE centre-motor cortex-working muscle sequence drives overall performance levels and, hence, fatigue symptoms. The sporting outputs from this sequence can be modulated by interactions with muscle afferent and circulatory feedback, psychological and decision-making inputs. Importantly, compensatory processes exist at many levels to protect against performance decrements. Small changes of putative fatigue factors can also be protective. We show that individual fatigue factors including diminished carbohydrate availability, elevated serotonin, hypoxia, acidosis, hyperkalaemia, hyperthermia, dehydration and reactive oxygen species, each contribute to several fatigue symptoms. Thus, multiple symptoms of fatigue can occur simultaneously and the underlying mechanisms overlap and interact. Based on this understanding, we reinforce the proposal that fatigue is best described globally as an exercise-induced decline of performance as this is inclusive of all viewpoints. © 2011 Adis Data Information BV.

Full Text Available Modern organization theory considers emotional intelligence as the index of competencies that help organizations to develop a vision for competitiveness. It also allows organizational leaders to enthusiastically commit to the vision, and energize organizational members to achieve the vision. To maximize competiveness organizations use models to simplify and clarify thinking, to identify important aspects, to suggest explanations and to predict consequences, and explore other performance areas that would otherwise be hidden in an excess of words. The survey research design was used to explore the relationship between emotional intelligence and organizational competitiveness. The study found that emotional intelligence has strong positive relationship with organizational competitiveness
CREATING COMPETITIVE ORGANIZATIONAL STRATEGY USING THE FUNNEL METHOD

Full Text Available In the highly competitive environment of the 21st century, organizations must be able to effectively change through the application of effective strategies, quickly and in a way that the competitors will be unable to imitate. Therefore, the essential question in any organization is how to achieve and maintain competitive advantage. In this regard, strategic leaders should first logically consider what will bring a substantial advantage to the organization in a long-term, and then start with the process of creating the strategy. To achieve this, researchers in the field of managerial issues offer a concept of continuous process that begins by looking at the customers pattern, through defining the competitive environment and the place of business in it and finally categorizing several strategic business conditions, as a precondition for election and creation of a competitive strategy. This process can be presented as the “funnel for selection of competitive strategy”, in whose widest part we can put the customer matrix, in the middle part we can place definitions of the business outlook of the business and the position of the organization in those perspectives. In order to implement the "Funnel method" of strategic planning teams we need accurate, timely and relevant information based on which we can bring appropriate organizational strategy. The subject of this paper is displaying the Funnel method for selection of the competitive strategy, and presentation of the situation in some of the organizations in the Pelagonija region, related to the way and the information used to create organizational strategies through the Funnel method.

Influence of export control policy on the competitiveness of machine tool producing organizations
Ahrstrom, Jeffrey D.
The possible influence of export control policies on producers of export controlled machine tools is examined in this quantitative study. International market competitiveness theories hold that market controlling policies such as export control regulations may influence an organization's ability to compete (Burris, 2010). Differences in domestic application of export control policy on machine tool exports may impose throttling effects on the competitiveness of participating firms (Freedenberg, 2010). Commodity shipments from Japan, Germany, and the United States to the Russian market will be examined using descriptive statistics; gravity modeling of these specific markets provides a foundation for comparison to actual shipment data; and industry participant responses to a user developed survey will provide additional data for analysis using a Kruskal-Wallis one-way analysis of variance. There is scarce academic research data on the topic of export control effects within the machine tool industry. Research results may be of interest to industry leadership in market participation decisions, advocacy arguments, and strategic planning. Industry advocates and export policy decision makers could find data of interest in supporting positions for or against modifications of export control policies.

With the increasing number of emerging contaminants that are cationic at environmentally relevant pH values, there is a need for robust predictive models of organic cation sorption coefficients (K d ). Current predictive models fail to account for the differences in the identity, abundance, and affinity of surface-associated inorganic exchange ions naturally present at negatively charged receptor sites on environmental solids. To better understand how organic cation sorption is influenced by surface-associated inorganic exchange ions, sorption coefficients of 10 organic cations (including eight pharmaceuticals and two simple probe organic amines) were determined for six homoionic forms of the aluminosilicate mineral, montmorillonite. Organic cation sorption coefficients exhibited consistent trends for all compounds across the various homoionic clays with sorption coefficients (K d ) decreasing as follows: K d Na + > K d NH 4 + ≥ K d K + > K d Ca 2+ ≥ K d Mg 2+ > K d Al 3+ . This trend for competition between organic cations and exchangeable inorganic cations is consistent with the inorganic cation selectivity sequence, determined for exchange between inorganic ions. Such consistent trends in competition between organic and inorganic cations suggested that a simple probe cation, such as phenyltrimethylammonium or benzylamine, could capture soil-to-soil variations in native inorganic cation identity and abundance for the prediction of organic cation sorption to soils and soil minerals. Indeed, sorption of two pharmaceutical compounds to 30 soils was better described by phenyltrimethylammonium sorption than by measures of benzylamine sorption, effective cation exchange capacity alone, or a model from the literature (Droge, S., and Goss, K. Environ. Sci. Technol. 2013, 47, 14224). A hybrid approach integrating structural scaling factors derived from this literature model of organic cation sorption, along with phenyltrimethylammonium K d values, allowed for

A widely agreed-upon feature of spoken word recognition is that multiple lexical candidates in memory are simultaneously activated in parallel when a listener hears a word, and that those candidates compete for recognition (Luce, Goldinger, Auer, & Vitevitch, Perception 62:615-625, 2000; Luce & Pisoni, Ear and Hearing 19:1-36, 1998; McClelland & Elman, Cognitive Psychology 18:1-86, 1986). Because the presence of those competitors influences word recognition, much research has sought to quantify the processes of lexical competition. Metrics that quantify lexical competition continuously are more effective predictors of auditory and visual (lipread) spoken word recognition than are the categorical metrics traditionally used (Feld & Sommers, Speech Communication 53:220-228, 2011; Strand & Sommers, Journal of the Acoustical Society of America 130:1663-1672, 2011). A limitation of the continuous metrics is that they are somewhat computationally cumbersome and require access to existing speech databases. This article describes the Phi-square Lexical Competition Database (Phi-Lex): an online, searchable database that provides access to multiple metrics of auditory and visual (lipread) lexical competition for English words, available at www.juliastrand.com/phi-lex .

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) was used to analyze a series of synthetic organic ions bearing fixed multiple charges. Despite the multiple intrinsic charges, only singly charged ions were recorded in each case. In addition to the pseudo-molecular ions formed by counterion adduction, deprotonation and electron capture, a number of fragment ions were also observed. Charge splitting by fragmentation was found to be a viable route for charge reduction leading to the formation of the observed singly charged fragment ions. Unlike multivalent metal ions, organic ions can rearrange and/or fragment during charge reduction. This fragmentation process will evidently complicate the interpretation of the MALDI MS spectrum. Because MALDI MS is usually considered as a soft ionization technique, the fragment ion peaks can easily be erroneously interpreted as impurities. Therefore, the awareness and understanding of the underlying MALDI-induced fragmentation pathways is essential for a proper interpretation of the corresponding mass spectra. Due to the fragment ions generated during charge reduction, special care should be taken in the MALDI MS analysis of multiply charged ions. In this work, the possible mechanisms by which the organic ions bearing fixed multiple charges fragment are investigated. With an improved understanding of the fragmentation mechanisms, MALDI TOF MS should still be a useful technique for the characterization of organic ions with fixed multiple charges.

Fluorescent organic dyes are currently the standard signal-generating labels used in microarray quantification. However, new labeling strategies are needed to meet the demand for high sensitivity in the detection of low-abundance proteins and small molecules. In this report, a long-chain DNA/dye conjugate was used to attach multiple fluorescence labels on antibodies to improve signal intensity and immunoassay sensitivity. Compared with the 30 base-pair (bp) oligonucleotide used in our previous work [Q. Zhang, L.-H. Guo, Bioconjugate Chem. 18 (2007) 1668-1672], conjugation of a 219 bp DNA in solution with a fluorescent DNA binder SYBR Green I resulted in more than sixfold increase in signal intensity, consistent with the increase in bp number. In a direct immunoassay for the detection of goat anti-mouse IgG in a mouse IgG-coated 96-well plate, the long DNA conjugate label also produced higher fluorescence than the short one, accompanied by about 15-fold improvement in the detection limit. To demonstrate its advantage in real applications, the DNA/dye conjugate was employed in the competitive immunoassay of 17beta-estradiol, a clinically and environmentally important analyte. The biotin-terminated DNA was attached to biotinylated anti-estradiol antibody through the biotin/streptavidin/biotin bridge after the immuno-reaction was completed, followed by conjugation with SYBR Green I. The limit of detection for 17beta-estradiol is 1.9 pg mL(-1), which is 200-fold lower than the assay using fluorescein-labeled antibodies. The new multiple labeling strategy uses readily available reagents, and is also compatible with current biochip platform. It has great potential in the sensitive detection of protein and antibody microarrays.

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

Performance Management in Healthcare Organizations: Concept and Practicum.
Dimitropoulos, Panagiotis E
2017-01-01
Organizational performance can create and sustain competitive advantages for corporations and even improve their sustainability and future prospects. Health care organizations present a sector where performance management is structured by multiple dimensions. The scope of this study is to analyze the issue of performance management in healthcare organizations and specifically the implementation of the Balanced Scorecard (BSC) methodology on organizations providing health services. The study provides a discussion on the BSC development process, the steps that management has to take in order to prepare the implementation of the BSC and finally discusses a practical example of a scorecard with specific strategic goals and performance indicators. Managers of healthcare organizations and specifically those providing services to the elderly and the general population could use the propositions of the study as a roadmap for processing, analyzing, evaluating and implementing the balanced scorecard approach in their organizations' daily operations. BSC methodology can give an advantage in terms of enhanced stakeholder management and preservation within a highly volatile and competitive economic environment.
Competitiveness: new economic paradigm?

Full Text Available Nowadays competitiveness is made up of “the new” paradigm that allows to prevail in the global World. Thus, it is inevitable to ask, was it required to be competitive to be successful in the international trade arena? Recognizing the discussion about it and its theoretical-conceptual density, the present paper studies this old notion whose meaning, in essence, is always the same one. This applies even though new realities in the present world-wide atmosphere confer to it a distinguishing character and new and old players are forced to organize actions and bring efforts together to obtain the competitive supremacy.

To investigate the short-term consequences of direct competition between beech and sycamore maple on root N uptake and N composition, mycorrhizal seedlings of both tree species were incubated for 4 days (i.e. beech only, sycamore maple only or both together) in an artificial nutrient solution with low N availability. On the fourth day, N uptake experiments were conducted to study the effects of competition on inorganic and organic N uptake. For this purpose, multiple N sources were applied with a single label. Furthermore, fine roots were sampled and analysed for total amino acids, soluble protein, total nitrogen, nitrate and ammonium content. Our results clearly show that both tree species were able to use inorganic and organic N sources. Uptake of inorganic and organic N by beech roots was negatively affected in the presence of the competing tree species. In contrast, the presence of beech stimulated inorganic N uptake by sycamore maple roots. Both the negative effect of sycamore maple on N uptake of beech and the positive effect of beech on N uptake of sycamore maple led to an increase in root soluble protein in beech, despite an overall decrease in total N concentration. Thus, beech compensated for the negative effects of the tree competitor on N uptake by incorporating less N into structural N components, but otherwise exhibited the same strategy as the competitor, namely, enhancing soluble protein levels in roots when grown under competition. It is speculated that enhanced enzyme activities of so far unknown nature are required in beech as a defence response to inter-specific competition.
Managing the market. Focusing on a select group of customers can keep an organization competitive.
MacStravic, R S
1989-05-01
The real challenge in healthcare marketing today is managing markets, focusing on selected groups of customers rather than on the organization or its services. Market management includes three distinct but related levels: Strategic market management assesses current and potential markets and chooses those the organization can serve best; segment management focuses on the needs and wants of subsets of chosen customers; and customer management reinforces long-term commitments to the organization. The patient care experience can be broken down into specific contacts with each staff member. The key to managing the experience is to identify and achieve standards of performance for each contact by examining what each event means to the patients and how patients judge each staff member, as well as the overall care experience. Regular feedback helps. An unavoidable risk in market management is that a given segment may decline in size, in need for services, or in cohesiveness as a segment. Yet those organizations which can identify the right segments and "manage" them effectively will have an advantage in a competitive market.

Full Text Available The study aims to analyze the factors related to organizational culture that assist in knowledge management processes, helping to generate competitive advantage in the companies of metal-mechanic sector. Therefore, a quantitative survey data collection strategy was performed by applying a structured questionnaire in a sample of 63 employees from 13 companies in the metal-mechanic sector. The results were analyzed using multiple regression and indicate that the studied segment, learning and trust are positive and significant predictors of knowledge management. Thus, it can be inferred that the companies that stimulate its employees to learn and invest in maintaining confidence among members of the organization may achieve better performance in knowledge management. Finally, the results also expose that the knowledge management directly influences the performance and organizational effectiveness, demonstrating that the use and sharing of tacit and explicit knowledge are generating competitive advantage to competitors.

Richard Hu
2015-02-01
Full Text Available This study injects sustainability into competitiveness to inform policy making and planning for contemporary urban development. This is built upon the recent advancement in the scholarship on urban competitiveness that demonstrates a clear deviation from an economic-centric approach to incorporate multiple dimensions of a city’s progress. This study has an explicit concern for environmental sustainability and its relationship with urban competitiveness and their conceptual and methodological articulations. Empirically, this study measures the sustainability and competitiveness in Australian cities and reveals that Australia’s urban progress is clearly associated with an environmental cost. The findings are useful to inform policy making and planning for building sustainable and competitive cities. Apart from the conventional solutions that focus on urban form change and transport infrastructure improvement, this study suggests a need to explore the opportunities deriving from the emerging smart city planning and practice.
Advances in Biodegradation of Multiple Volatile Organic Compounds
Zhang, M.; Yoshikawa, M.
2017-12-01
Bioremediation of soil and groundwater containing multiple contaminants remains a challenge in environmental science and engineering because complete biodegradation of all components is necessary but very difficult to accomplish in practice. This presentation provides a brief overview on advances in biodegradation of multiple volatile organic compounds (VOCs) including chlorinated ethylenes, benzene, toluene and dichloromethane (DCM). Case studies on aerobic biodegradation of benzene, toluene and DCM, and integrated anaerobic-aerobic biodegradation of 7 contaminants, specifically, tetrachloroethylene (PCE), trichloroethylene (TCE), cis-dichloroethylene (cis-DCE), vinyl chloride (VC), DCM, benzene and toluene will be provided. Recent findings based on systematic laboratory experiments indicated that aerobic toluene degradation can be enhanced by co-existence of benzene. Propioniferax, not a known benzene, toluene and DCM degrader can be a key microorganism that involves in biodegradation when the three contaminants co-exist. Integrated anaerobic-aerobic biodegradation is capable of completely degrading the seven VOCs with initial concentrations less than 30 mg/L. Dehalococcoides sp., generally considered sensitive to oxygen, can survive aerobic conditions for at least 28 days, and can be activated during the subsequent anaerobic biodegradation. This presentation may provide a systematic information about biodegradation of multiple VOCs, and a scientific basis for the complete bioremediation of multiple contaminants in situ.

Full Text Available Competition has become a current and difficult problem for any organization. This raises the need for the companies to obtain competitive advantages. One way to do this is making use of appropriate information technology, which is the task of information systems for top management. Computer technology and data communication technology alter the parameters within which competition unfolds in all fields. Whereas in the past information technology was oriented to data storage, in the modern world it must provide a dynamic vision on the organization, facilitating adaptation to changes in business environment and thus ensuring competitiveness. In this way, information technology becomes a competitive weapon which is extremely effective in achieving the objectives of the organization. In addition, it is applicable in any field of activity regardless of the organization’s size.

This article examines a model of competition between two types of health insurer: Health Maintenance Organizations (HMOs) and nonintegrated insurers. HMOs vertically integrate health care providers and pay them at a competitive price, while nonintegrated health insurers work as indemnity plans and pay the health care providers freely chosen by policyholders at a wholesale price. Such difference is referred to as an input price effect which, at first glance, favors HMOs. Moreover, we assume that policyholders place a positive value on the provider diversity supplied by their health insurance plan and that this value increases with the probability of disease. Due to the restricted choice of health care providers in HMOs a risk segmentation occurs: policyholders who choose nonintegrated health insurers are characterized by higher risk, which also tends to favor HMOs. Our equilibrium analysis reveals that the equilibrium allocation only depends on the number of HMOs in the case of exclusivity contracts between HMOs and providers. Surprisingly, our model shows that the interplay between risk segmentation and input price effects may generate ambiguous results. More precisely, we reveal that vertical integration in health insurance markets may decrease health insurers' premiums.
THE MULTIPLE CHOICE PROBLEM WITH INTERACTIONS BETWEEN CRITERIA

Luiz Flavio Autran Monteiro Gomes
2015-12-01
Full Text Available ABSTRACT An important problem in Multi-Criteria Decision Analysis arises when one must select at least two alternatives at the same time. This can be denoted as a multiple choice problem. In other words, instead of evaluating each of the alternatives separately, they must be combined into groups of n alternatives, where n = 2. When the multiple choice problem must be solved under multiple criteria, the result is a multi-criteria, multiple choice problem. In this paper, it is shown through examples how this problemcan be tackled on a bipolar scale. The Choquet integral is used in this paper to take care of interactions between criteria. A numerical application example is conducted using data from SEBRAE-RJ, a non-profit private organization that has the mission of promoting competitiveness, sustainable developmentand entrepreneurship in the state of Rio de Janeiro, Brazil. The paper closes with suggestions for future research.

Simulations at multiple levels were performed to investigate the aqueous adsorption of phthalate esters (PAEs) on carbon nanoparticles and to find the competitive effect of a low molecular weight natural organic acid (benzoic acid) on the adsorption process. Six PAEs of varying alkyl side chain lengths and three carbon-based nanomaterials including a single-walled carbon nanotube (SWNT), double-walled carbon nanotube (DWNT), and graphene (G) were studied. Results showed that the adsorption energies calculated using density functional theory increase with increasing length of the PAE alkyl chain. G exhibits higher adsorption capacity for the PAEs than SWNT and DWNT. The absolute adsorption energies of these systems also display a positive linear correlation with the hydrophobicity of the PAE molecules. Molecular dynamics simulations indicate that the presence of neutral/anionic benzoic acid in water alleviates the PAE adsorption. Furthermore, anionic benzoic acid exerts more impact on the PAE adsorption than the neutral form.
CORPORATE CULTURE AND COMPETITION

ROGOJANU Angela
2009-12-01
Full Text Available Culture is one of those terms that are difficult to express distinctly, but everyone knows it when they sense it. Many articles have been written in recent years about corporate culture, which can be looked at as a system. Inputs include feedback from society, professions, laws, stories, heroes, values on competition or service, etc. Outputs are organizational behaviors, technologies, strategies, image, products, services, appearance, etc. Most organizations don't consciously try to create a certain culture, as it is typically created unconsciously, based on the values of the top management or the founders of an organization. In this paper we try to see whether corporate culture has any influence on competition and if it has, whether it is a positive one or a negative one.
Electricity market competition and nuclear power
International Nuclear Information System (INIS)
Varley, C.; Paffenbarger, J.
1999-01-01
Throughout the world, the Organization for Economic Cooperation and Development (OECD) member countries' governments are promoting competitive electricity markets. In particular, there is a move away from administrative price-setting by government institutions to market price-setting through the introduction of competition. Today this is often focused on competition in generation. However, competition among final electricity suppliers and distributors to provide effective consumer choice is a further step that governments are likely to pursue as experience with market reform grows. This competitive environment will undoubtedly impact upon the nuclear generation industry. Competition will provide an opportunity to reinvigorate nuclear power; it will improve the transparency of energy policy-making and the policy framework for nuclear power; it will spur innovation in existing plants and help prospects for new plant build; and provide a strong impetus for cost reduction and innovation. This paper discusses these issues in detail. It looks at the potential benefits and challenges to the nuclear generation industry arising from an increasingly competitive market. (author)
Cell Competition: Roles and Importance as a Central Phenomenon.
Patel, Manish; Antala, Bhavesh; Shrivastava, Neeta
2015-01-01
Cell competition is a type of short-range cell-cell interaction first observed in Drosophila melanogaster. In two heterogeneous cell populations, cells that have a higher fitness level would have a competitive advantage and grow at the cost of neighbor cells that have comparatively lower fitness. This interaction is due to differences in expression levels of a specific protein in the two cell populations, and it is known as cell competition. In this review, we have studied recent findings of cell competition in different biological processes in Drosophila as well as mammalian systems. The purpose of this review is to collate important studies of competitive cell interactions, and to understand its roles and importance as a central phenomenon. This review provides evidence of the relevance of cell competition in various physiological and pathological conditions, such as size control in organ development, stem cell maintenance, tissue repair, organ regeneration, aging, formation of memory, and cancer.
Organic vs. Non-Organic Food Products: Credence and Price Competition

2017-04-01
Full Text Available We analyze the organic and non-organic production choices of two firms by considering customers’ trust in organic food products. In the context of customers’ possible willingness to pay a premium price and their mistrust in organic food products, two firms first make choices on offering organic and non-organic food products. If offering organic products, a firm can further invest in the credence system to increase customers’ trust in their organic products. At the final stage, two firms determine prices. We provide serval insights. First, we characterize the market conditions in which only one firm, both firms or neither firm will choose to offer organic food products. We find that the higher the production costs or credence investment costs for organic food products are, the more likely firms are to choose to produce non-organic food products. Second, if it is expensive enough to invest in organic credence, offering organic food products may still be uncompetitive, even if organic production cost appears to have no disadvantage compared to non-organic food products. Third, we highlight how the prices of organic food products in equilibrium are affected by market parameters. We show that when only one firm offers organic food products, this firm tends to offer a relatively low price if organic credence investment is expensive. Fourth, we highlight how one firm’s credence investment decision in equilibrium can be affected by the product type choice of the other firm. We find that the investment in organic credence is lower when both firms offer organic food products compared with the case when only one firm offers organic food products.

Micronutrient metal speciation is driven by competitive organic chelation in grassland soils.
Boiteau, R.; Shaw, J. B.; Paša-Tolić, L.; Koppenaal, D.; Jansson, J.
2017-12-01
Many elements are scarcely soluble in aqueous conditions found in high pH environments, such as calcareous grassland soils, unless complexed to strong binding organic ligands. To overcome this limitation, some plants and microbes produce chelators that solubilize micronutrient metals such as Fe, Ni, Cu, and Zn from mineral phases. These complexes are taken up by organisms via specific membrane receptors, thereby differentially impacting the bioavailability of these metals to the plant and microbial community. Although the importance of these chelation strategies for individual organisms has been well established, little is known about which pathways coexist within rhizosphere microbiomes or how they interact and compete for metal binding. Identifying these metallo-organic species within natural ecosystems has remained a formidable analytical challenge due to the vast diversity of compounds and poorly defined metabolic processes in complex soil matrix. Herein, we employed recently developed liquid chromatography (LC) mass spectrometry (MS) methods to characterize the speciation of water-soluble dissolved trace elements (Fe, Ni, Cu, and Zn) from Kansas Prairie soil. Both plant and fungal chelators were identified, revealing compound-specific patterns of chelation to biologically essential metals. Numerous metabolites typically implicated in plant iron acquisition and homeostasis, including mugineic acids, deoxymugineic acid, nicotianamine, and hydroxynicotianamine, dominated the speciation of divalent metals such as Ni, Cu, and Zn (2-57 pmol / g soil). In contrast, the fungal siderophore ferricrocine bound comparatively more trivalent Fe (9pmol / g soil). These results define biochemical pathways that underpin the regulation of metals in the grassland rhizosphere. They also raise new questions about the competition of these compounds for metal binding and their bioavailability to different members of the rhizosphere population.

We hypothesized that the change in donor profile over the years influenced the percentage of transplantations. We reviewed medical records for all multiple-organ donors (MODs) within our network. The percentage of transplanted organs was compared between 1991-1992 (A) and 2006-2007 (B). In period A, 156 potential MODs were identified compared with 278 in period B. Fifteen potential donors (10%) in period A and 114 (41%) in period B were rejected because they were medically not suitable (40% vs 75%) or there was no family consent (60% vs 25%). Of the remaining effective MODs (141 in period A and 164 in period B), mean (standard deviation = SD) age was 34 (5) years vs 49 (17) years (P organs transplanted in periods A vs B was kidneys, 97% vs 79%; livers, 64% vs 85%; hearts, 60% vs 26%; lungs, 7% vs 35%; and pancreas, 6% vs 13% (P organs (17%), mainly because of medical contraindications. The MOD profile changed to older age, fewer traumatic brain deaths, and longer ventilation time. We transplanted more livers, lungs, and pancreases but fewer kidneys and hearts.

We propose an approach for the simultaneous bounding box estimation of multiple organs in volumetric CT images. Local eigen-organ spaces are constructed for different types of training organs, and a global eigen-space, which describes the spatial relationships between the organs, is also constructed. Each volume of interest in the abdominal CT image is projected into the local eigen-organ spaces, and several candidate locations are determined. The final selection of the organ locations is made by projecting the set of candidate locations into the global eigen-space. A probabilistic atlas of organs is used to eliminate locations with low probability and to guide the selection of candidate locations. Evaluation by the leave-one-out method using 10 volumetric abdominal CT images showed that the proposed method provided an average accuracy of 80.38% for 11 different organ types. (author)

As most of the supply chains in practice are decentralized, a key issue in supply chain management is to study the coordination of supply chain. The interactions among players are typically of two types, viz. vertical competition and horizontal competition. We use a game theoretic framework to analyze a two-stage supply chain. The supply chain is modeled as a Stackelberg game with a manufacturer as leader and multiple retailers as followers. We consider multiple retailers competing on quantit...

Full Text Available Purpose: The purpose of this paper is to analyze the characteristics that make information systems useful in gathering and processing information with the aim of organizational learning and subsequent structural adaptation for better fitting to market requirements. Design/methodology/approach: Adaptation is a must when turning to foster the competitiveness and sustainability of the organization. Findings and Originality/value: It is clear that information systems can really create a difference in the way an organization acquires information from its environment and from itself in order to achieve a high-quality decision taking process. Research limitations/implications: Organizations have to look inside themselves in order to ensure the comprehension of their core competencies and the way they carry them out. Practical implications: Organizational learning is one of the means employed by organizations to get adapted to their surrounding environment. Social implications: Systems engineering techniques can be applied in order to leverage these core competencies and make organizations adaptable to the organizational environment requirements through the use of information systems. Originality/value: To obtain competitive advantages in the market. Keywords: competitive advantage, information systems, knowledge management, & the learning organization.
Seeking the competitive advantage: it's more than cost reduction.
South, S F
1999-01-01
Most organizations focus considerable time and energy on reducing operating costs as a way to attain marketplace advantage. This strategy was not inappropriate in the past. To be competitive in the future, however, focus must be placed on other issues, not just cost reduction. The near future will be dominated by service industries, knowledge management, and virtual partnerships, with production optimization and flexibility, innovation, and strong partnerships defining those organizations that attain competitive advantage. Competitive advantage will reside in clarifying the vision and strategic plan, reviewing and redesigning work processes to optimize resources and value-added work, and creating change-ready environments and empowered workforces.

2015-01-01
Recently, we proposed that Brainets, i.e. networks formed by multiple animal brains, cooperating and exchanging information in real time through direct brain-to-brain interfaces, could provide the core of a new type of computing device: an organic computer. Here, we describe the first experimental demonstration of such a Brainet, built by interconnecting four adult rat brains. Brainets worked by concurrently recording the extracellular electrical activity generated by populations of cortical ...
Optimizing multiple-choice tests as tools for learning.
Little, Jeri L; Bjork, Elizabeth Ligon
2015-01-01
Answering multiple-choice questions with competitive alternatives can enhance performance on a later test, not only on questions about the information previously tested, but also on questions about related information not previously tested-in particular, on questions about information pertaining to the previously incorrect alternatives. In the present research, we assessed a possible explanation for this pattern: When multiple-choice questions contain competitive incorrect alternatives, test-takers are led to retrieve previously studied information pertaining to all of the alternatives in order to discriminate among them and select an answer, with such processing strengthening later access to information associated with both the correct and incorrect alternatives. Supporting this hypothesis, we found enhanced performance on a later cued-recall test for previously nontested questions when their answers had previously appeared as competitive incorrect alternatives in the initial multiple-choice test, but not when they had previously appeared as noncompetitive alternatives. Importantly, however, competitive alternatives were not more likely than noncompetitive alternatives to be intruded as incorrect responses, indicating that a general increased accessibility for previously presented incorrect alternatives could not be the explanation for these results. The present findings, replicated across two experiments (one in which corrective feedback was provided during the initial multiple-choice testing, and one in which it was not), thus strongly suggest that competitive multiple-choice questions can trigger beneficial retrieval processes for both tested and related information, and the results have implications for the effective use of multiple-choice tests as tools for learning.
Capitalist collective action: competition, cooperation and conflict in the coal industry
Energy Technology Data Exchange (ETDEWEB)

2006-11-15
This volume presents a theory of capitalist collective action and a case study of the pre-World War II American coal industry to which the theory is applied. The author examines the irony of capitalist firms that do not want to compete with each other, but often cannot avoid doing so. He then explains under what conditions businesses would be able to organize their competition and identifies the economic and political factors that facilitate or inhibit this organization. The case study not only illustrates the theory, but demonstrates how the competitive relations of capitalist firms are critically important determinants of their political behavior. The author argues that the traditional Marxist concern with conflict between workers and capitalists should be supplemented with a concern for the competitive conflicts among capitalists. Contents are: 1: 1. Economic competition and market organization: the logic of capitalist collective action; 2. Forms of capitalist collective action; Part II: 3. Price and wage games in the bituminous coal industry; 4. Workers organize capitalists: collective bargaining and market organization, 1880-1914; 5. The coal industry on the defensive, 1916-1922; 6. Labor-capital conflict and the disorganization of the coal market, 1921-1928; 7. From free competition to state intervention; Part III: 8. Capitalists, workers, and the state; Bibliography; Indexes. This text was originally published in 1989 in hardback (ISBN 0-521-36265-2).

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
Imaging cell competition in Drosophila imaginal discs.

Cell competition is a process in which cells with higher fitness ("winners") survive and proliferate at the expense of less fit neighbors ("losers"). It has been suggested that cell competition is involved in a variety of biological processes such as organ size control, tissue homeostasis, cancer progression, and the maintenance of stem cell population. By advent of a genetic mosaic technique, which enables to generate fluorescently marked somatic clones in Drosophila imaginal discs, recent studies have presented some aspects of molecular mechanisms underlying cell competition. Now, with a live-imaging technique using ex vivo-cultured imaginal discs, we can dissect the spatiotemporal nature of competitive cell behaviors within multicellular communities. Here, we describe procedures and tips for live imaging of cell competition in Drosophila imaginal discs. Copyright © 2012 Elsevier Inc. All rights reserved.

Human immunodeficiency virus type 1 (HIV-1) replication efficiency or fitness, as measured in cell culture, has been postulated to correlate with clinical outcome of HIV infection, although this is still controversial. One limitation is the lack of high-throughput assays that can measure replication efficiency over multiple rounds of replication. We have developed a multiple-cycle growth competition assay to measure HIV-1 replication efficiency that uses flow cytometry to determine the relative proportions of test and reference viruses, each of which expresses a different reporter gene in place of nef. The reporter genes are expressed on the surface of infected cells and are detected by commercially available fluorescence-labeled antibodies. This method is less labor-intensive than those that require isolation and amplification of nucleic acids. The two reporter gene products are detected with similar specificity and sensitivity, and the proportion of infected cells in culture correlates with the amount of viral p24 antigen produced in the culture supernatant. HIV replication efficiencies of six different drug-resistant site-directed mutants were reproducibly quantified and were similar to those obtained with a growth competition assay in which the relative proportion of each variant was measured by sequence analysis, indicating that recombination between the pol and reporter genes was negligible. This assay also reproducibly quantified the relative fitness conferred by protease and reverse transcriptase sequences containing multiple drug resistance mutations, amplified from patient plasma. This flow cytometry-based growth competition assay offers advantages over current assays for HIV replication efficiency and should prove useful for the evaluation of patient samples in clinical trials.
Sourcing strategies to keep up with competition: the case of SAP
Directory of Open Access Journals (Sweden)
Michelle Antero
2014-01-01
Full Text Available This paper applies the Red Queen theory to explain how organizations utilize various sourcing arrangements in order to compete in an evolutionary arms race where only the strongest competitors will survive. The case study incorporates competition, and views sourcing strategies as a means to improve the firm’s viability to survive competition in the marketplace. The study begins by positioning the Red Queen theory within the sourcing literature. It subsequently applies the framework to a case study of SAP AG to illustrate how sourcing strategies have changed over time in response to the logic of competition. The case study reveals that (a organizations are adaptive systems and capable of learning to make strategic changes pertaining to sourcing arrangements; (b organizations select the terms on which they want to compete by developing certain capabilities within the firm; (c organizations are reflexive and over time develop competitive hysteresis which allows them to become stronger competitors. In the case of SAP AG, various sourcing arrangements were selected over its 40-year history to respond to technological and market changes.

Interspecific competition influences the organization of a diverse sessile insect community
Cornelissen, Tatiana; de Carvalho Guimarães, Carla Daniele; Rodrigues Viana, João Paulo; Silva, Bárbara
2013-10-01
Interspecific competition has played a major role in determining the effects of species interactions in terrestrial communities and the perception of its role on shaping population dynamics and community structure has changed throughout the years. In this study, we evaluated the existence of interspecific competition in the herbivore community of the dioecious plant Baccharis pseudomyriocephala (Asteraceae), which holds a diverse community of gall-forming insects. Sixty plants were studied and gall richness and abundance among plants were evaluated. To address whether a plant already occupied by a gall species is preferred or avoided by another gall species, null models were used for all 60 plants combined and for male and female plants separately. Our results have shown that the 11 species of gall-formers found on B. pseudomyriocephala co-occur less than expected by chance alone, indicating that interspecific competition might be an important force structuring the insect community in this tropical host plant, regardless of plant gender.

Occasionally systemic complications with high risk of death, such as multiple organ dysfunction syndrome (MODS), can occur following multiple bee stings. This case study reports a patient who presented with MODS, i.e., acute kidney injury, hepatic and cardiac dysfunction, after multiple bee stings. The standard clinical findings were then correlated with magnetic resonance imaging (MRI) findings, which demonstrates that MRI may be utilized as a simpler tool to use than other multiple diagnostics.
COMPETITIVENESS - KEY ISSUES OF THE ROMANIAN ECONOMY
Directory of Open Access Journals (Sweden)
Gabriela-Liliana, CIOBAN
2014-11-01
Full Text Available Based on the theory that competitiveness plays an increasingly powerful role in creating prosperity, wealth, a large number of economists, researchers, scientists, highlight a number of approaches aimed, on the one hand, on the analysis of competitiveness at national or regional level, and on the other hand, on the ability of local firms to achieve competitive products and to commercialize them in the extern markets. In this context we aim to analyze and develop strategies and methods to help identify competitive areas at a national level. This is necessary because in our opinion the competitiveness of a company and / or country is more than wealth itself; it means a systematic process of wealth creation, plus a social system in which most citizens have access to material wealth. We consider in this respect that a country cannot automatically be considered competitive only if it is rich in natural resources. In our view, a competitive country creates wealth through labor, talent and organization and thus it manages to have a productive and creative potential making it independent of material resources.

Full Text Available A competitive structure of a national economy is influenced by the competitiveness of each of the actors made the national economy. In other words, to achieve competitive economic structure shall contribute all sectors of the national economy and hence all branches of the national economy, all organizations within each branch. Thus, the productive sectors of the economy contribute by increasing their competitiveness, GDP growth, added value, while other branches making a contribution through activity, increased quality of life (health, culture, social in training skilled labor (education to ensure effective functioning of the judiciary, protection of private property and citizen safety, lower crime rate (police, reducing the risk of political instability, increasing social cohesion, social disparities (richness and extreme poverty, and discrimination against women and minority groups. Human resources are probably the most important factor determining the competitiveness of an area. The ability of a country to move up the value chain is closely related to human resource capability. In understanding the competitive evaluation is important to assess not only in terms of education, improvement, skills and work experience, but also in terms of other attributes, more difficult to measure, as entrepreneurial relationships, creativity and risk tolerance. Secondly, we must accept that individual productivity is determined by external factors. Latent potential of the individual can develop when the person moves to another environment that provides better and more opportunities. Currently structural changes to remain competitive obtaining essential parameters of the Romanian economy to cope with competitive pressures of the single European market.
Market responses to HMOs: price competition or rivalry?
McLaughlin, C G
1988-01-01
Although competition for consumers is increasing in the health care sector, there is disagreement about whether it is resulting in cost containment, as its supporters have argued it would. In part this stems from a confusion between price competition, which under ideal circumstances leads to the production of services at the lowest possible cost, and nonprice competition--or rivalry--which under many circumstances will lead to increased costs. In this paper, I examine the evidence about the competitive response to the growing presence of health maintenance organizations in the health care marketplace. The available evidence suggests that providers are responding not with classical cost-containing price competition but, instead, with cost-increasing rivalry, characterized by increased expenditures to promote actual or perceived product differentiation.
Explaining gender differences in competitiveness: Gender-task stereotypes
Große, Niels Daniel; Riener, Gerhard

Gender-specific patterns of self-selection into competitive and cooperative environments may have multiple reasons. One of the most prominent explanations to this point is, that there are inherent differences between men and women when it comes to preferences regarding competition. We take a different point of view and claim that gender-task stereotypes are able to explain a large part of the under-representation of women in tournament like environments. We conduct an experiment with a quanti...

All social organisms experience dilemmas between cooperators performing group-beneficial actions and cheats selfishly exploiting these actions. Although bacteria have become model organisms to study social dilemmas in laboratory systems, we know little about their relevance in natural communities. Here, we show that social interactions mediated by a single shareable compound necessary for growth (the iron-scavenging pyoverdine) have important consequences for competitive dynamics in soil and pond communities of Pseudomonas bacteria. We find that pyoverdine non- and low-producers co-occur in many natural communities. While non-producers have genes coding for multiple pyoverdine receptors and are able to exploit compatible heterologous pyoverdines from other community members, producers differ in the pyoverdine types they secrete, offering protection against exploitation from non-producers with incompatible receptors. Our findings indicate that there is both selection for cheating and cheating resistance, which could drive antagonistic co-evolution and diversification in natural bacterial communities.Lab strains of Pseudomonas are model systems for the evolution of cooperation over public goods (iron-scavenging siderophores). Here, Butaitė et al. add ecological and evolutionary insight into this system by showing that cheating and resistance to cheating both shape competition for iron in natural Pseudomonas communities.
CEO perceptions of competition--and strategic response in hospital markets.
Alexander, J A; Burns, L R; Morrisey, M A; Johnson, V
2001-06-01
Physician-organization integration (POI) has emerged as a key issue for hospitals and health systems seeking to improve the quality and cost-effectiveness of care. Although competition and managed care are often cited as primary market drivers of the adoption of POI strategies, prior research has shown only weak associations between these market attributes and POI. This article argues that the role of key organizational decision makers has not been adequately accounted for in explaining strategic change. The study examines the role of hospital CEO perceptions of competition in predicting the adoption of five different approaches to POI. CEO perceptions of general market competition are explained by a combination of market and organizational attributes. Furthermore, when controlling for objective characteristics of the environment and organization, CEO perceptions of competition have consistent, statistically significant associations with four of five measures of POI examined.
Competitive sorption of persistent organic pollutants onto microplastics in the marine environment

Bakir, Adil; Rowland, Steven J.; Thompson, Richard C.
2012-01-01
Highlights: ► Organic pollutants are present as complex mixtures in the marine environment. ► The competitive sorption of phenanthrene and DDT in a bi-solute system was investigated onto PVC and PE. ► DDT outcompeted phenanthrene for sorption onto plastic. ► DDT also appeared to have a negative effect on the sorption of phenanthrene onto plastic when added at high concentration. - Abstract: Plastics are known to sorb persistent organic pollutants from seawater. However, studies to quantify sorption rates have only considered the affinity of chemicals in isolation, unlike the conditions in the environment where contaminants are present as complex mixtures. Here we examine whether phenanthrene and 4,4′-DDT, in a mixture, compete for sorption sites onto PVC with no added additives (unplasticised PVC or uPVC) and Ultra-High Molecular Weight polyethylene. Interactions were investigated by exposing particles of uPVC and UHMW PE to mixtures of 3H and 14C radiolabelled Phe and DDT. Changes in sorption capacity were modelled by applying a Freundlich binding sorption isotherms. An Extended Langmuir Model and an Interaction Factor Model were also applied to predict equilibrium concentrations of pollutants onto plastic. This study showed that in a bi-solute system, DDT exhibited no significantly different sorption behaviour than in single solute systems. However, DDT did appear to interfere with the sorption of Phe onto plastic, indicating an antagonistic effect.

Experimental evolution of sperm competitiveness in a mammal

Full Text Available Abstract Background When females mate with multiple partners, sperm from rival males compete to fertilise the ova. Studies of experimental evolution have proven the selective action of sperm competition on male reproductive traits. However, while reproductive traits may evolve in response to sperm competition, this does not necessarily provide evidence that sperm competitive ability responds to selection. Indeed, a study of Drosophila failed to observe divergence in sperm competitive ability of males in lines selected for enhanced sperm offence and defence. Results Adopting the naturally polygamous house mouse (Mus domesticus as our vertebrate model, we performed an experimental evolution study and observed genetic divergence in sperm quality; males from the polygamous selection lines produced ejaculates with increased sperm numbers and greater sperm motility compared to males from the monogamous lines. Here, after 12 generations of experimental evolution, we conducted competitive matings between males from lineages evolving under sperm competition and males from lineages subject to relaxed selection. We reduced variation in paternity arising from embryo mortality by genotyping embryos in utero at 14 days gestation. Our microsatellite data revealed a significant paternity bias toward males that evolved under the selective regime of sperm competition. Conclusion We provide evidence that the sperm competitiveness phenotype can respond to selection, and show that improved sperm quality translates to greater competitive fertilisation success in house mice.

The effect of competition of Cu(II) and Ni(II) on the kinetic stability of Cr(III) complexed with natural organic matter (NOM) was characterized using EDTA exchange with single-stage tangential-flow ultrafiltration. For a water sample from Serra de Itabaiana, 3% of spiked Cr(III) was exchanged, while for a sample from the Itapanhaú River, 7, 10, 10, and 21% was exchanged in experiments using Cr(III) alone and in combination with Cu(II), Ni(II), or Cu(II) + Ni(II), respectively. Times required to reach exchange equilibrium with EDTA were less than 360 min. The influence of competition from Ni(II) and Cu(II) on the availability of complexed Cr(III) was low, demonstrating preference of the ligand sites for Cr(III). This was correlated with sample humification, as confirmed by EPR and (13)C NMR analyses. Exchange efficiency was in the order Cu > Ni > Cr, and the process could be readily described by first order kinetics, with average rate constants of 0.35-0.37 h(-1). Copyright © 2015 Elsevier Ltd.

The invasive species Spartina alterniflora and native species Phragmites australis display a significant co-occurrence zonation pattern and this co-exist region exerts most competitive situations between these two species, competing for the limited space, directly influencing the co-exist distribution in the future. However, these two species have different growth ratios in this area, which increase the difficulty to detect the distribution situation directly by remote sensing. As chlorophyll content is a key indicator of plant growth and physiological status, the objective of this study was to reduce the effect of interspecies competition when estimating Cab content; we evaluated 79 published representative indices to determine the optimal indices for estimating the chlorophyll a and b (Cab) content. After performing a sensitivity analysis for all 79 spectral indices, five spectral indices were selected and integrated using an artificial neural network (ANN) to estimate the Cab content of different competition ratios: the Gitelson ratio green index, the transformed chlorophyll absorption ratio index/optimized soil-adjusted vegetation index, the modified normalized difference vegetation index, the chlorophyll fluorescence index, and the Vogelmann chlorophyll index. The ANN method yielded better results (R 2 = 0.7110 and RMSE = 8.3829 μg cm -2 ) on average than the best single spectral index (R 2 = 0.6319 and RMSE = 9.3535 μg cm -2 ), representing an increase of 10.78% in R 2 and a decrease of 10.38% in RMSE. Our results indicated that integrating multiple vegetation indices with an ANN can alleviate the impact of interspecies competition and achieve higher estimation accuracy than the traditional approach using a single index.

By using two donor materials, poly(3-hexylthiosphene) (P3HT) and titanyl phthalocyanine (TiOPc), as well as two acceptor materials, [6,6]-phenyl C61 butyric acid methyl ester (PCBM) and C60, the cascade multiple heterojunctions of P3HT:PCBM/TiOPc:C60/C60 have been constructed. Applying the optimized inverted configuration of FTO/Zinc Tin Oxide (ZTO)/C60 (30 nm)/TiOPc:C60 (1:1.5, 25 nm)/P3HT:PCBM (1:0.8, 100 nm)/MoO3 (4 nm)/Ag, the considerably enhanced open circuit voltage (VOC) and short circuit current (JSC) can be harvested together, and the power conversion efficiency (PCE) is three times higher than that of the control cell with conventional structure. The significant improvements of the inverted cell are mostly due to the broadened spectral absorption and high efficient multi-interface exciton dissociation in the cascade multiple heterojunctions, indicating that the optimized cascade heterojunctions match the inverted structure well.

Full Text Available This paper offers an ethnomusicological perspective on competitions of guslars (players of a single-stringed musical instrument gusle predominantly used to accompany the voice of a singer reciting epic poetry, here interpreted as a specific form of public music performance. First competitions were organized between World Wars (1924-1933, afterwards being established in 1971 and since then organized (with a short interruption in Serbia, Montenegro and the Republic of Srpska. Apart from gusle players and the audience participating in this interaction, these competitions introduced into the focus the very organizers as well. The importance of collectivity as an idea interwoven into epic ethos has become a powerful means of manipulation used by authorities. Their interests have been put forward primarily through the poetic content of new songs. Ideology, though, is not only reflected in the competition repertoire. It is also felt in other forms of public gusle playing practice (such as performances with miscellaneous programme, concerts etc.. The sense of competitiveness, as a type of communicational situation, is far strongly felt in the music dimension. Limited in duration, the performance was reduced to only fragments of songs, which, on the other side, caused a change in gusle playing. The traditional style implied economizing with player’s energy and dramatization tailored to suit the context of long-lasting songs, whereas per-forming of fragments resulted in a more grandiose style aimed at making momentary impression: intensive, vigorous singing in the upper vocal register, using a wide range of expressive devices within short time etc. After studying the competition rules, key formal regulations, and the organization of competitions so far, I discerned that those epic poems have been dominantly regarded as poetry. One of crucial reasons for this is wider communicability of verbal to music discourse, but also more straightforward conveyance

As an emerging halogenated organic contaminant, Dechlorane Plus (DP) was scarcely reported in marine environments, especially in China. In this work, 35 surface sediments and a sediment core were collected across the Southern Yellow Sea (SYS) to comprehensively explore the spatio-temporal distribution and possible migration pathway of DP. DP concentrations ranged from 14.3 to 245.5 pg/g dry weight in the surface sediments, displaying a seaward increasing trend with the high levels in the central mud zone. This spatial distribution pattern was ascribed to that fine particles with the elevated DP levels were preferentially transported to the central mud zone under hydrodynamic forcing and/or via long-range atmospheric transportation and deposition. DP concentrations in sediment core gradually increased from the mid-1950s to present, which corresponded well with the historical production and usage of DP, as well as the economic development in China. Significantly positive correlation between DP and total organic carbon (TOC) in both surface sediments and sediment core indicated TOC-dependent natural deposition of DP in the SYS. We used multiple biomarkers, for the first time, to explore the potential effects of terrestrial and marine organic matters (TOM and MOM) on DP deposition. The results showed that competition may occur between TOM and MOM for DP adsorption, and MOM was the predominant contributor in controlling DP deposition in the marine sediments from the SYS. - Highlights: • Effects of TOM and MOM on DP deposition were first explored by multi-biomarkers. • Hydrodynamic forcing and atmospheric deposition were responsible for DP in the SYS. • MOM was the predominant contributor in controlling DP deposition to sediments in the SYS. • Competition may occur between TOM and MOM for DP adsorption. - This study was the first attempt to comprehensively explore the effects of TOM and MOM on DP deposition in marine sediments from the SYS.
Fitness costs of intrinsic competition in two egg parasitoids of a true bug.
Cusumano, Antonino; Peri, Ezio; Boivin, Guy; Colazza, Stefano
2015-10-01
Intrinsic competition in insect parasitoids occurs when supernumerary larvae develop in the same host as consequence of multiple ovipositions by females of the same species (intra-specific competition) or by females of different species (inter-specific competition). Studies on intrinsic competition have mainly focused on understanding the factors that play a role in the outcome of competition, while fitness-related effects for the parasitoid surviving the competition have been poorly investigated, especially in egg parasitoids. Interestingly, even the winning parasitoid can experience fitness costs due to larval development in a host in which multiple factors have been injected by the ovipositing females or released by their larvae. In this paper we studied fitness-related traits associated with intra- and inter-specific competition between Trissolcus basalis (Wollaston) and Ooencyrtus telenomicida (Vassiliev), the main egg parasitoids associated with the southern green stink bug Nezara viridula (L.) in Italy. We investigated the impact of intrinsic competition for the surviving parasitoid in terms of body size, developmental time, number and size of oocytes. Our results indicated that T. basalis adults did not experience fitness-related costs when surviving intra-specific competition; however, adults were smaller, took longer to develop and females produced fewer oocytes after surviving inter-specific competition. A different outcome was found for O. telenomicida where the emerging females were smaller, produced fewer and smaller oocytes when suffering intra-specific competition whereas no fitness costs were found when adults survived inter-specific competition. These results support the hypothesis that the impact of intrinsic competition in egg parasitoids depends on the severity of the competitive interaction, as fitness costs were more pronounced when the surviving parasitoid interacted with the most detrimental competitor.

As a syndrome, multiple organ dysfunction (MODS) is defined as an altered organ function in the setting of sepsis, septic shock or systemic inflammatory response syndrome (SIRS) and is the most common cause of death in intensive care units. Endotoxin, a constituent of cell walls of Gram-negative bacteria, plays an important role in the initiation and development of MODS. The cytokines, especially tumor necrosis factor alpha (TNF-alpha), are early regulators of the immune response and can induce the release of secondary cytokines. To remove endotoxin and TNF-alpha from patients with MODS, the adsorption method has proven to be most effective. In this review, we provide various methods of removal of endotoxins and TNF-alpha using different adsorbents. (topical review)

Establishment of a knowledge management in organization will ensure sustainable competitive advantage because the intellectual capital has become the primary bases of core competencies and the key to superior performance. The transition from industrial to knowledge society, effective use of knowledge is one of the deciding factors in the struggle for competitiveness because it will ensure the rationality, efficiency and flexibility in operations, and only through the realization of those graphics company can gain a competitive advantage on the market.
Using the Web for Competitive Intelligence (CI) Gathering
Rocker, JoAnne; Roncaglia, George

Businesses use the Internet as a way to communicate company information as a way of engaging their customers. As the use of the Web for business transactions and advertising grows, so too, does the amount of useful information for practitioners of competitive intelligence (CI). CI is the legal and ethical practice of information gathering about competitors and the marketplace. Information sources like company webpages, online newspapers and news organizations, electronic journal articles and reports, and Internet search engines allow CI practitioners analyze company strengths and weaknesses for their customers. More company and marketplace information than ever is available on the Internet and a lot of it is free. Companies should view the Web not only as a business tool but also as a source of competitive intelligence. In a highly competitive marketplace can any organization afford to ignore information about the other players and customers in that same marketplace?

Full Text Available Hydatid disease is the most common parasitic infection in the world, and is caused by the parasite Echinococcus granulosus. The most common site of this disease is the liver (75%, followed by the lungs, kidney, bones, and brain. Multiple abdominal organ and peritoneal involvement can also be seen in some cases. The dissemination of hydatid cyst disease can develop spontaneously or secondary to trauma or surgery. Here, we present the case of a 69-year-old man with multiple cyst hydatidosis, who underwent surgery for acute appendicitis approximately 20 years previously. Computed tomography of the abdomen shows the multiple active and inactive cystic lesions in the liver, spleen, right kidney, and mesentery. This patient required surgery several times, as well as medical treatment, after the rupture of a mesenteric hydatid cyst during the appendectomy. Combined anthelmintic treatment was recommended to the patient who refused further surgical treatment.

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.
Does competition improve health care quality?

To identify the effect of competition on health maintenance organizations' (HMOs) quality measures. Longitudinal analysis of a 5-year panel of the Healthcare Effectiveness Data and Information Set (HEDIS) and Consumer Assessment of Health Plans Survey(R) (CAHPS) data (calendar years 1998-2002). All plans submitting data to the National Committee for Quality Assurance (NCQA) were included regardless of their decision to allow NCQA to disclose their results publicly. NCQA, Interstudy, the Area Resource File, and the Bureau of Labor Statistics. Fixed-effects models were estimated that relate HMO competition to HMO quality controlling for an unmeasured, time-invariant plan, and market traits. Results are compared with estimates from models reliant on cross-sectional variation. Estimates suggest that plan quality does not improve with increased levels of HMO competition (as measured by either the Herfindahl index or the number of HMOs). Similarly, increased HMO penetration is generally not associated with improved quality. Cross-sectional models tend to suggest an inverse relationship between competition and quality. The strategies that promote competition among HMOs in the current market setting may not lead to improved HMO quality. It is possible that price competition dominates, with purchasers and consumers preferring lower premiums at the expense of improved quality, as measured by HEDIS and CAHPS. It is also possible that the fragmentation associated with competition hinders quality improvement.

A key issue is how networks in the brain learn to perform path integration, that is update a represented position using a velocity signal. Using head direction cells as an example, we show that a competitive network could self-organize to learn to respond to combinations of head direction and angular head rotation velocity. These combination cells can then be used to drive a continuous attractor network to the next head direction based on the incoming rotation signal. An associative synaptic modification rule with a short term memory trace enables preceding combination cell activity during training to be associated with the next position in the continuous attractor network. The network accounts for the presence of neurons found in the brain that respond to combinations of head direction and angular head rotation velocity. Analogous networks in the hippocampal system could self-organize to perform path integration of place and spatial view representations.

Biochemical and genetic aspects of the metabolism of the amino sugars N-acetylglucosamine (GlcNAc) and glucosamine (GlcN) by commensal oral streptococci and the effects of these sugars on interspecies competition with the dental caries pathogen Streptococcus mutans were explored. Multiple S. mutans wild-type isolates displayed long lag phases when transferred from glucose-containing medium to medium with GlcNAc as the primary carbohydrate source, but commensal streptococci did not. Competition in liquid coculture or dual-species biofilms between S. mutans and Streptococcus gordonii showed that S. gordonii was particularly dominant when the primary carbohydrate was GlcN or GlcNAc. Transcriptional and enzymatic assays showed that the catabolic pathway for GlcNAc was less highly induced in S. mutans than in S. gordonii Exposure to H2O2, which is produced by S. gordonii and antagonizes the growth of S. mutans, led to reduced mRNA levels of nagA and nagB in S. mutans When the gene for the transcriptional regulatory NagR was deleted in S. gordonii, the strain produced constitutively high levels of nagA (GlcNAc-6-P deacetylase), nagB (GlcN-6-P deaminase), and glmS (GlcN-6-P synthase) mRNA. Similar to NagR of S. mutans (NagRSm), the S. gordonii NagR protein (NagRSg) could bind to consensus binding sites (dre) in the nagA, nagB, and glmS promoter regions of S. gordonii Notably, NagRSg binding was inhibited by GlcN-6-P, but G-6-P had no effect, unlike for NagRSm This study expands the understanding of amino sugar metabolism and NagR-dependent gene regulation in streptococci and highlights the potential for therapeutic applications of amino sugars to prevent dental caries. Amino sugars are abundant in the biosphere, so the relative efficiency of particular bacteria in a given microbiota to metabolize these sources of carbon and nitrogen might have a profound impact on the ecology of the community. Our investigation reveals that several oral commensal bacteria have a much

To protect brittle layers in organic photovoltaic devices, the mechanical neutral plane strategy can be adopted through placing the brittle functional materials close to the neutral plane where stress and strain are zero during bending. However, previous research has been significantly limited in the location and number of materials to protect through using a single neutral plane. In this study, multiple neutral planes are generated using low elastic modulus adhesives and are controlled through quantitative analyses in order to protect the multiple brittle materials at various locations. Moreover, the protection of multiple brittle layers at various locations under both concave and convex bending directions is demonstrated. Multilayer structures that have soft adhesives are further analyzed using the finite element method analysis in order to propose guidelines for structural design when employing multiple neutral planes.

The concept of continuity of care by intensivists as an element of quality control in the medical care of Intensive Care Unit (ICU) patients surviving multiple organ dysfunction syndrome has led to a rethinking of the ICU model in recent years. We discuss the rationale to design and implement a hospital-based, prospective, randomized, multicenter Intervention/Control study in order to estimate the impact of an interdisciplinary intervention during the post-ICU recovery phase on medium-term medical outcomes in ICU patients with multiple organ dysfunction.

We developed a supportive care team for hopelessly ill patients in an urban emergency/trauma hospital. The team includes a clinical nurse specialist and a faculty physician as well as a chaplain and social worker. The supportive care team provides an alternative to intensive care or conventional ward management of hopelessly ill patients and concentrates on the physical and psychosocial comfort needs of patients and their families. We describe our experience with 20 hopelessly ill patients with multiple organ failure vs a similar group treated before the development of the supportive care team. Although there was no difference in mortality (100 percent), the length of stay in the medical ICU for patients with multiple organ failure decreased by 12 days to 6 days. Additionally, there were 50 percent fewer therapeutic interventions provided by the supportive care team vs intensive care or conventional ward treatment of multiple organ failure patients. We describe the methods that the supportive care team uses in an attempt to meet the physical and psychosocial comfort needs of hopelessly ill multiple organ failure patients and their families. This multidisciplinary approach to the care of the hopelessly ill may have applications in other institutions facing the ethical, medical, and administrative challenges raised by these patients.

Full Text Available The transportation infrastructure always plays an important role in the development of the local tourism. A system dynamics method incorporated with a destination choice model is proposed in this paper to analyze the dynamic impacts of transportation infrastructure on the tourism development, where multiple tourism destinations share a common market. Tourists’ destination choice behaviors are characterized by a multinomial logit choice model based on the utility of destinations, which depends heavily on the accessibility of destinations that the local administration has strong willingness to improve. The system dynamics method is used to model dynamic interactions among destinations and to simulate the dynamic evolution of the competition on the tourism market. A case study of the World Cultural Heritage Sites, Xidi and Hongcun villages, shows the competition for road infrastructure investment can produce a win-win situation and bring the cooperation on investment due to the positive externality of transport infrastructure and two villages show a tendency to merge into one bigger destination. Finally, the tourism development strategies for two villages are discussed based on the scenario analysis.

Why should organisms incur a cost in order to inflict a (usually greater) cost on others? Such costly harming behavior may be favored when competition for resources occurs locally, because it increases individuals' fitness relative to close competitors. However, there is no explicit experimental...... evidence supporting the prediction that people are more willing to harm others under local versus global competition. We illustrate this prediction with a game theoretic model, and then test it in a series of economic games. In these experiments, players could spend money to make others lose more. We...... manipulated the scale of competition by awarding cash prizes to the players with the highest payoffs per set of social partners (local competition) or in all the participants in a session (global competition). We found that, as predicted, people were more harmful to others when competition was local (study 1...
Antagonistic interactions between plant competition and insect herbivory.
Schädler, Martin; Brandl, Roland; Haase, Josephine
2007-06-01
Interspecific competition between plants and herbivory by specialized insects can have synergistic effects on the growth and performance of the attacked host plant. We tested the hypothesis that competition between plants may also negatively affect the performance of herbivores as well as their top-down effect on the host plant. In such a case, the combined effects of competition and herbivory may be less than expected from a simple multiplicative response. In other words, competition and herbivory may interact antagonistically. In a greenhouse experiment, Poa annua was grown in the presence or absence of a competitor (either Plantago lanceolata or Trifolium repens), as well as with or without a Poa-specialist aphid herbivore. Both competition and herbivory negatively affected Poa growth. Competition also reduced aphid density on Poa. This effect could in part be explained by changes in the biomass and the nitrogen content of Poa shoots. In treatments with competitors, reduced aphid densities alleviated the negative effect of herbivory on above- and belowground Poa biomass. Hence, we were able to demonstrate an antagonistic interaction between plant-plant interspecific competition and herbivory. However, response indices suggested that antagonistic interactions between competition and herbivory were contingent on the identity of the competitor. We found the antagonistic effect only in treatments with T. repens as the competitor. We conclude that both competitor identity and the herbivore's ability to respond with changes in its density or activity to plant competition affect the magnitude and direction (synergistic vs. antagonistic) of the interaction between competition and herbivory on plant growth.

A search engine to identify pathway genes from expression data on multiple organisms

Zambon Alexander C
2007-05-01
Full Text Available Abstract Background The completion of several genome projects showed that most genes have not yet been characterized, especially in multicellular organisms. Although most genes have unknown functions, a large collection of data is available describing their transcriptional activities under many different experimental conditions. In many cases, the coregulatation of a set of genes across a set of conditions can be used to infer roles for genes of unknown function. Results We developed a search engine, the Multiple-Species Gene Recommender (MSGR, which scans gene expression datasets from multiple organisms to identify genes that participate in a genetic pathway. The MSGR takes a query consisting of a list of genes that function together in a genetic pathway from one of six organisms: Homo sapiens, Drosophila melanogaster, Caenorhabditis elegans, Saccharomyces cerevisiae, Arabidopsis thaliana, and Helicobacter pylori. Using a probabilistic method to merge searches, the MSGR identifies genes that are significantly coregulated with the query genes in one or more of those organisms. The MSGR achieves its highest accuracy for many human pathways when searches are combined across species. We describe specific examples in which new genes were identified to be involved in a neuromuscular signaling pathway and a cell-adhesion pathway. Conclusion The search engine can scan large collections of gene expression data for new genes that are significantly coregulated with a pathway of interest. By integrating searches across organisms, the MSGR can identify pathway members whose coregulation is either ancient or newly evolved.

Full Text Available Due to the high similarity in their requirements for space and food, close bacterial relatives may be each other's strongest competitors. Close bacterial relatives often form visible boundaries to separate their swarming colonies, a phenomenon termed colony-merger incompatibility. While bacterial species are known to have many incompatible strains, it is largely unclear which traits lead to multiple incompatibilities and the interactions between multiple incompatible siblings. To investigate the competitive interactions of closely related incompatible strains, we mutated Myxococcus xanthus DK1622, a predatory bacterium with complex social behavior. From 3392 random transposon mutations, we obtained 11 self-identification (SI deficient mutants that formed unmerged colony boundaries with the ancestral strain. The mutations were at nine loci with unknown functions and formed nine independent SI mutants. Compared with their ancestral strain, most of the SI mutants showed reduced growth, swarming and development abilities, but some remained unchanged from their monocultures. When pairwise mixed with their ancestral strain for co-cultivation, these mutants exhibited improved, reduced or unchanged competitive abilities compared with the ancestral strain. The sporulation efficiencies were affected by the DK1622 partner, ranging from almost complete inhibition to 360% stimulation. The differences in competitive growth between the SI mutants and DK1622 were highly correlated with the differences in their sporulation efficiencies. However, the competitive efficiencies of the mutants in mixture were inconsistent with their growth or sporulation abilities in monocultures. We propose that the colony-merger incompatibility in M. xanthus is associated with multiple independent genetic loci, and the incompatible strains hold competitive interaction abilities, which probably determine the complex relationships between multiple incompatible M. xanthus strains and

Competition and rural primary care programs.
Ricketts, T C
1990-04-01
Rural primary care programs were established in areas where there was thought to be no competition for patients. However, evidence from site visits and surveys of a national sample of subsidized programs revealed a pattern of competitive responses by the clinics. In this study of 193 rural primary care programs, mail and telephone surveys produced uniform data on the organization, operation, finances, and utilization of a representative sample of clinics. The programs were found to compete in terms of: (1) price, (2) service mix, (3) staff availability, (4) structural accessibility, (5) outreach, and (6) targeting a segment of the market. The competitive strategies employed by the clinics had consequences that affected their productivity and financial stability. The strategies were related to the perceived missions of the programs, and depended heavily upon the degree of isolation of the program and the targeting of the services. The competitive strategy chosen by a particular program could not be predicted based on service area population and apparent competitors in the service area. The goals and objectives of the programs had more to do with their competitive responses than with market characteristics. Moreover, the chosen strategies may not meet the demands of those markets.

Full Text Available Evolution of cooperation and competition can appear when multiple adaptive agents share a biological, social, or technological niche. In the present work we study how cooperation and competition emerge between autonomous agents that learn by reinforcement while using only their raw visual input as the state representation. In particular, we extend the Deep Q-Learning framework to multiagent environments to investigate the interaction between two learning agents in the well-known video game Pong. By manipulating the classical rewarding scheme of Pong we show how competitive and collaborative behaviors emerge. We also describe the progression from competitive to collaborative behavior when the incentive to cooperate is increased. Finally we show how learning by playing against another adaptive agent, instead of against a hard-wired algorithm, results in more robust strategies. The present work shows that Deep Q-Networks can become a useful tool for studying decentralized learning of multiagent systems coping with high-dimensional environments.

Terms of economic theory terms, it is necessary to build a strategy that will produce super profits, ie. strategy that will enable the efficient exploitation of knowledge companies to win competitive advantage. It is assumed that knowledge in its explicit or implicit manifestations can be managed. The question is how to develop a knowledge management strategy that would exploit this valuable resource and protect its value. Possibility of knowledge management is becoming increasingly important in today's so-called. knowledge economy (knowledge economy. The creation and dissemination of knowledge within modern organizations is becoming increasingly crucial factor in achieving and maintaining its competitive advantage. In fact, the only sustainable competitive advantage of modern organizations derives from what the company knows, how efficiently used what you know and how quickly acquire and use new knowledge.

Full Text Available The economic conditions of recent times require a structural changing and, mainly, behavioral ones of Brazilian business. The scenario created by big economic powers shows the difference between Brazilian industries and service sectors when it is compared business issues, for example, competitiveness, productivity and innovation, with others countries. The technological innovation consists in a critical factor for competitiveness and for the global economic development; moreover, it can be found in industrial sectors (responsible for materialization and organization of operational system of production process and in service sectors (which make planning of the contracted activity. Innovation should not be included only in these two economic sectors; however, it has to be included in the economic thought of countries. It has to be highlighted the fact that innovation is not the unique factor of competitiveness, but, productivity and knowledge make the same impact in competitiveness as innovation does. Besides, external and internal demands predict trends in terms of searching products, process an strategies, which can promote a better interaction between market and productivity control. In a global context, Brazil, specially, has a lot of techniques to learn in terms of how to use its resources in a adequate way, independently if they are natural or not. That is why studies about critical factors for competitiveness are determined for the Brazil's sustainable growth.

A model tested among 136 Norwegian Olympic-level athletes yielded two paths related to performance. The first path indicated that self-confidence, modeled as an antecedent of competitive anxiety, is negatively correlated with anxiety. Competitive anxiety in turn is negatively correlated with performance. The second path indicated that group cohesion is positively correlated with group goal-clarity, which in turn is positively correlated with performance. Competitive anxiety mediates the relation between self-confidence and performance, whereas group goal-clarity mediates the relation between group cohesion and performance. Results from multiple regression analyses supported the model in the total sample and among individual sport athletes organized in training groups (n = 100). Among team sport athletes (n = 36), personality and group measures are more strongly intercorrelated than among individual sport athletes, and the relation with performance is more complex for the former group. The interaction of self-confidence and competitive anxiety is related to performance among team sport athletes.

Full Text Available A choice prediction competition is organized that focuses on decisions from experience in market entry games (http://sites.google.com/site/gpredcomp/ and http://www.mdpi.com/si/games/predict-behavior/. The competition is based on two experiments: An estimation experiment, and a competition experiment. The two experiments use the same methods and subject pool, and examine games randomly selected from the same distribution. The current introductory paper presents the results of the estimation experiment, and clarifies the descriptive value of several baseline models. The experimental results reveal the robustness of eight behavioral tendencies that were documented in previous studies of market entry games and individual decisions from experience. The best baseline model (I-SAW assumes reliance on small samples of experiences, and strong inertia when the recent results are not surprising. The competition experiment will be run in May 2010 (after the completion of this introduction, but they will not be revealed until September. To participate in the competition, researchers are asked to E-mail the organizers models (implemented in computer programs that read the incentive structure as input, and derive the predicted behavior as an output. The submitted models will be ranked based on their prediction error. The winners of the competition will be invited to publish a paper that describes their model.
Organizational Structure and Product Market Competition

We analyze an interaction between a firm’s choice of organizational structure and competition in the product-market. Two organizational structures are considered, namely a centralized-organization, whereby formal authority is retained by a principal, and a decentralized-organization, whereby formal authority is delegated to an agent. We show that the choice of organizational structure hinges on a trade-off between operating-profit and managerial effort. The principal may prefer to choose an o...
Sperm competition selects for sperm quantity and quality in the Australian Maluridae.
Rowe, Melissah; Pruett-Jones, Stephen
2011-01-25
When ejaculates from rival males compete for fertilization, there is strong selection for sperm traits that enhance fertilization success. Sperm quantity is one such trait, and numerous studies have demonstrated a positive association between sperm competition and both testes size and the number of sperm available for copulations. Sperm competition is also thought to favor increases in sperm quality and changes in testicular morphology that lead to increased sperm production. However, in contrast to sperm quantity, these hypotheses have received considerably less empirical support and remain somewhat controversial. In a comparative study using the Australian Maluridae (fairy-wrens, emu-wrens, grasswrens), we tested whether increasing levels of sperm competition were associated with increases in both sperm quantity and quality, as well as an increase in the relative amount of seminiferous tubule tissue contained within the testes. After controlling for phylogeny, we found positive associations between sperm competition and sperm numbers, both in sperm reserves and in ejaculate samples. Additionally, as sperm competition level increased, the proportion of testicular spermatogenic tissue also increased, suggesting that sperm competition selects for greater sperm production per unit of testicular tissue. Finally, we also found that sperm competition level was positively associated with multiple sperm quality traits, including the proportion of motile sperm in ejaculates and the proportion of both viable and morphologically normal sperm in sperm reserves. These results suggest multiple ejaculate traits, as well as aspects of testicular morphology, have evolved in response to sperm competition in the Australian Maluridae. Furthermore, our findings emphasize the importance of post-copulatory sexual selection as an evolutionary force shaping macroevolutionary differences in sperm phenotype.

Full Text Available Keeping a company in the top performing players in the relevant market depends not only on its ability to develop continually, sustainably and balanced, to the standards set by the customer and competition, but also on the ability to protect its strategic information and to know in advance the strategic information of the competition. In addition, given that economic markets, regardless of their profile, enable interconnection not only among domestic companies, but also between domestic companies and foreign companies, the issue of economic competition moves from the national economies to the field of interest of regional and international economic organizations. The stakes for each economic player is to keep ahead of the competition and to be always prepared to face market challenges. Therefore, it needs to know as early as possible, how to react to others’ strategy in terms of research, production and sales. If a competitor is planning to produce more and cheaper, then it must be prepared to counteract quickly this movement. Competitive intelligence helps to evaluate the capabilities of competitors in the market, legally and ethically, and to develop response strategies. One of the main goals of the competitive intelligence is to acknowledge the role of early warning and prevention of surprises that could have a major impact on the market share, reputation, turnover and profitability in the medium and long term of a company. This paper presents some aspects of competitive intelligence, mainly in terms of information analysis and intelligence generation. Presentation is theoretical and addresses a structured method of information analysis - scenarios method – in a version that combines several types of analysis in order to reveal some interconnecting aspects of the factors governing the activity of a company.

Research has returned mixed results concerning the relationship between prosocial motivation and citizenship behavior. Building from research suggesting that mixed motives might explain these equivocal findings, we conducted two field studies examining the interaction between prosocial and competitive motives and two types of citizenship behavior. Prosocial motivation, but not competitive motivation, was positively related to citizenship behavior directed at others, though this relationship was weakened when prosocial motives were accompanied by competitive motives. Prosocial motives compensated for weak competitive motives to predict citizenship behavior directed toward the organization. Our studies expand research on prosocial and competitive motivation, mixed-motives, and citizenship behavior. Further, they carry personnel implications given that many organizations seek to hire employees high on both competitive and prosocial motivation.
Contemporary Patterns of Multiple Organ Dysfunction in Trauma.
Shepherd, Joanna M; Cole, Elaine; Brohi, Karim
2017-04-01
Multiple organ dysfunction syndrome (MODS) is associated with poor outcomes for trauma patients. Different forms of MODS may exist and have different consequences. The ability to distinguish them clinically may have implications for prognosis and treatment. We wished to study whether prolonged MODS (PRMODS) could be observed as a distinct clinical entity to early resolving MODS (ERMODS) in critically injured patients. Adult major trauma patients recruited to a prospective observational study at a single major trauma center were eligible for inclusion. MODS was defined as Sequential Organ Failure Assessment (SOFA) score >5; and PRMODS as lasting >7 days. Time to recovery (TTR) was calculated as the number of days before the SOFA fell below the MODS threshold (≤5). Five hundred ninety-five patients were enrolled of whom 285 developed ERMODS (48%) and 184 (31%) PRMODS. Organ dysfunction was more severe and protracted in PRMODS, especially in patients without brain injury (mean SOFA 11 vs. 6, Day 2, P < 0.001; TTR 17 vs. 3 days, P < 0.001). PRMODS exhibited higher rates of hepatic and renal dysfunction (84% vs. 56%; and 78% vs. 47%, P≤0.001). Patterns of recovery were distinct in hepatic, renal, and neurological systems (TTR 15 vs. 4; 20 vs. 3; and 28 vs. 7 days, P < 0.01). PRMODS was associated with higher infection and mortality rates (91% vs. 41%; and 22% vs. 7%, P < 0.001). PRMODS appears common, a distinct clinical entity, and associated with worse patient outcomes. PRMODS may represent an important endpoint for studies evaluating outcomes following trauma.

Full Text Available In the process of globalization of world economic processes, the role of individual national economies increases, comparative advantages of the development of a country are formed, and their competitiveness is ensured. That is why it is worth emphasizing the importance of increasing the competitiveness of each individual country, based on its internal capacity. In a broad aspect, the competitiveness of the national economy is perceived as the ability of the country to ensure the balance of its external proportions and to avoid those constraints imposed by the foreign economic sphere, to self-organizing the improvement of their world economic ties. The competitiveness of the economy at the macro level is associated with the duration of the cycle of reproduction of the main productive assets and, accordingly, the jobs, productive forces of society and determined by the overall economic efficiency of investment. The criteria of competitiveness of the national economy are the growth of social productivity of labor, increase of social and economic efficiency of production and standard of living of the population. The competitiveness of the national economy determines sustainable socio-economic development of the country, as well as sustainable development predetermines the competitiveness of not only the country, but also all its levels. Scientific results are obtained using special methods of research of economic objects and phenomena, that is, based on the correlation and regressive, comparative analysis (establishing the relationship between the indicator factor, as well as economic modeling. Findings. Generalizing analysis and the importance of the macroeconomic aspect of competitiveness were used in the research paper, which will allow to better respond to the economic situation, in accordance with the trends of the “green” transformation of the economy; which in turn will solve important problems of the development and implementation of its
No arousal-biased competition in focused visuospatial attention.
Ásgeirsson, Árni Gunnar; Nieuwenhuis, Sander
2017-11-01
Arousal sometimes enhances and sometimes impairs perception and memory. A recent theory attempts to reconcile these findings by proposing that arousal amplifies the competition between stimulus representations, strengthening already strong representations and weakening already weak representations. Here, we report a stringent test of this arousal-biased competition theory in the context of focused visuospatial attention. Participants were required to identify a briefly presented target in the context of multiple distractors, which varied in the degree to which they competed for representation with the target, as revealed by psychophysics. We manipulated arousal using emotionally arousing pictures (Experiment 1), alerting tones (Experiment 2) and white-noise stimulation (Experiment 3), and validated these manipulations with electroencephalography and pupillometry. In none of the experiments did we find evidence that arousal modulated the effect of distractor competition on the accuracy of target identification. Bayesian statistics revealed moderate to strong evidence against arousal-biased competition. Modeling of the psychophysical data based on Bundesen's (1990) theory of visual attention corroborated the conclusion that arousal does not bias competition in focused visuospatial attention.

Competition among Turkish hospitals and its effect on hospital efficiency and service quality.
Torun, Nazan; Celik, Yusuf; Younis, Mustafa Z
2013-01-01
The level of competition among hospitals in Turkey was analyzed for the years 1990 through 2006 using the Herfindahl-Hirschman Index (HHI). Multiple and simple regression analyses were run to observe the development of competition among hospitals over this period of time, to examine likely determinants of competition, and to calculate the effects of competition on efficiency and quality in individual hospitals. This study found that the level of competition among hospitals in Turkey has increased throughout the years. Also, competition has had a positive effect on the efficiency of hospitals; however, it did not have a significant positive effect on their quality. Moreover, there are important differences in the level of competition among hospitals that vary according to the geographical region, the type of ownership, and the type of hospital. This study is one of the first to evaluate the effects of health policies on competition as well as the effects of increasing competition on hospital quality and efficiency in Turkey.

Full Text Available Competitive environment of today’s organizations, more than ever, is extensive, and the major concern for managers is to preserve and promote the sustainable competitive advantage. Companies have an obligation to improve their product quality and have extensive and close cooperation with other companies involved in the supply chain of products. Supply chain quality management (SCQM is a systematic approach to improve the performance that integrates supply chain partners and uses the opportunity in the best way, establish linkages between upstream and downstream flows, and investigate on creating value and satisfaction of intermediaries and final customers. Furthermore, achieving competitive advantages enables an organization to create a remarkable position in market and differentiate itself from competitors. This paper aims to understand the relationships between SCQM and competitive advantage. Sixty-eight experts of 25 companies in Sahami Alyaf (SA supply chain has been participated in this research. The research method used for this article is descriptive correlation. To assess the relationships between the criteria, canonical correlation analysis was used. The result shows that the SCQM and competitive advantages have a meaningful relationship. It also shows that most important variable in the linear combination of SCQM and competitive advantages are “customer focus and quality,” respectively.
Pervasive competition between threat and reward in the brain.
Choi, Jong Moon; Padmala, Srikanth; Spechler, Philip; Pessoa, Luiz
2014-06-01
In the current functional MRI study, we investigated interactions between reward and threat processing. Visual cues at the start of each trial informed participants about the chance of winning monetary reward and/or receiving a mild aversive shock. We tested two competing hypothesis: according to the 'salience hypothesis', in the condition involving both reward and threat, enhanced activation would be observed because of increased salience; according to the 'competition hypothesis', the processing of reward and threat would trade-off against each other, leading to reduced activation. Analysis of skin conductance data during a delay phase revealed an interaction between reward and threat processing, such that the effect of reward was reduced during threat and the effect of threat was reduced during reward. Analysis of imaging data during the same task phase revealed interactions between reward and threat processing in several regions, including the midbrain/ventral tegmental area, caudate, putamen, bed nucleus of the stria terminalis, anterior insula, middle frontal gyrus and dorsal anterior cingulate cortex. Taken together, our findings reveal conditions during which reward and threat trade-off against each other across multiple sites. Such interactions are suggestive of competitive processes and may reflect the organization of opponent systems in the brain. © The Author (2013). Published by Oxford University Press.

Competition and habitat selection in a forest-floor small mammal fauna
Energy Technology Data Exchange (ETDEWEB)
Dueser, R D [Univ. of Virginia, Charlottesville; Hallett, J G
1980-01-01
In a study of habitat exploitation in a forest-floor small mammal community, we have collected habitat and population data for Peromyscus leucopus, Ochrotomys nuttalli, and Tamias striatus. Using multiple regression analysis, researchers estimate the effects of habitat selection and competition on the local distributions of these species during three seasons. Each of the partial regression coefficients relating the density of an independent species to the density of the dependent species is negative. This result indicates that competition is pervasive among these species. Competitive ability and habitat selectivity both increase in the order Peromyscus-Tamias-Ochrotomys. Peromyscus is a poorly competitive habitat generalist, Ochrotomys is a strongly competitive habitat specialist, and Tamias is intermediate in both respects. The competitive hierarchy is stable between seasons. These results both confirm the conclusions reached in previous studies of this small mammal community and suggest the design of experiments to further clarify the mode and consequences of interaction between these species.
Competition and disclosure incentives: an empirical study of HMOs.
Jin, Ginger Zhe
2005-01-01
I examine Health Maintenance Organizations' (HMOs) voluntary disclosure of product quality, which is not as complete as unraveling theories predict. After controlling for cost and demand factors, I find that HMOs use voluntary disclosure to differentiate from competitors, with lower disclosure rates in highly competitive markets. These findings are consistent with product differentiation, but challenge the intuition that competition should lead to more provision of quality information.
Achieving competitive advantage through strategic human resource management.
Fottler, M D; Phillips, R L; Blair, J D; Duran, C A
1990-01-01
The framework presented here challenges health care executives to manage human resources strategically as an integral part of the strategic planning process. Health care executives should consciously formulate human resource strategies and practices that are linked to and reinforce the broader strategic posture of the organization. This article provides a framework for (1) determining and focusing on desired strategic outcomes, (2) identifying and implementing essential human resource management actions, and (3) maintaining or enhancing competitive advantage. The strategic approach to human resource management includes assessing the organization's environment and mission; formulating the organization's business strategy; assessing the human resources requirements based on the intended strategy; comparing the current inventory of human resources in terms of numbers, characteristics, and human resource management practices with respect to the strategic requirements of the organization and its services or product lines; formulating the human resource strategy based on the differences between the assessed requirements and the current inventory; and implementing the appropriate human resource practices to reinforce the strategy and attain competitive advantage.
Radionuclide sorption in soils and sediments: oxide-organic matter competition
International Nuclear Information System (INIS)
Maes, A.; Cremers, A.
1986-01-01
This paper deals with the speciation of europium in the solid phase and liquid phase extracts of Boom Clay under in situ conditions. Using a new method for measuring the europium-humic acid complex stability constant at high pH, it is shown that carbonate complexation is poorly competitive with humic acid, europium being quantitatively present as humic acid complex, its stability constant being of the order of 10 12 -10 13 . It is furthermore shown that partial oxidation of the sediment, which is strongly reducing under in situ conditions, leads to a significant increase in Ksub(D) values, whatever the liquid/solid ratio used. This effect is ascribed to the involvement of ferric oxides which are generated in the solid phase and which lead to a displacement of the metal from the humic acid sink. Some examples are presented which demonstrate that at high pH, around 9, ferric oxides may be competitive with humic acids for metal sorption and that this effect increases with pH. (author)

Full Text Available One of the most severe events occurring in critically ill patients admitted to a neonatal intensive care unit (NICU center is represented by the multiple organ failure (MOF, a systemic inflammatory response leading to a progressive organ dysfunction and mortality in newborns. MOF may occur in newborns primarily affected by multiple single organ diseases, including respiratory distress syndrome neonatal sepsis with acute kidney injury, post-asphyxial hypoxic-ischemic encephalopathy and pandemic influenza A (H1N1 infection. In a previous article from our group, based on the histological examination of all organs at autopsy of newborns affected by MOF, all organs studied did not escape to be damaged, including thymus and pancreas normally not mentioned in the literature of MOF. The aim of this article is to review the most important pathological changes pathologists should look for in every case of MOF occurring in the perinatal period, with particular attention to systemic endothelial changes occurring in blood vessels in all organs and sytems. On the basis of our experience, matching data during the last phases of the clinicopathological diagnosis represents a useful method, much more productive as compared to the method based on giving pathological answers to the clinical questions prospected before autopsy. As for the pathological features observed in neonatal MOF, one of them deserves a particular attention: the vascular lesions, and in particular the multiple changes occurring during MOF development in endothelial cells, ending with the loss of the endothelial barrier, probably the most relevant histological lesion followed by the insurgence of interstitial edema and disseminated intravascular coagulation. Small vessels should be observed at high power, with particular attention to the size and shape of endothelial nuclei, in order to evidence endothelial swelling, probably the initial modification of the endothelial cells leading to their

Full Text Available Introduction. Education of a competitive student is a strategically significant problem of the system of higher education in modern social and economic conditions. 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

Mathematics and engineering in real life through mathematical competitions
More, M.
2018-02-01
We bring out an experience of organizing mathematical competitions that can be used as a medium to motivate the student and teacher minds in new directions of thinking. This can contribute to fostering research, innovation and provide a hands-on experience of mathematical concepts with the real world. Mathematical competitions can be used to build curiosity and give an understanding of mathematical applications in real life. Participation in the competition has been classified under four broad categories. Student can showcase their findings in various forms of expression like model, poster, soft presentation, animation, live performance, art and poetry. The basic focus of the competition is on using open source computation tools and modern technology, to emphasize the relationship of mathematical concepts with engineering applications in real life.
Competition for trophies triggers male generosity.
Directory of Open Access Journals (Sweden)
Xiaofei Sophia Pan
Full Text Available BACKGROUND: Cooperation is indispensable in human societies, and much progress has been made towards understanding human pro-social decisions. Formal incentives, such as punishment, are suggested as potential effective approaches despite the fact that punishment can crowd out intrinsic motives for cooperation and detrimentally impact efficiency. At the same time, evolutionary biologists have long recognized that cooperation, especially food sharing, is typically efficiently organized in groups living on wild foods, even absent formal economic incentives. Despite its evident importance, the source of this voluntary compliance remains largely uninformed. Drawing on costly signaling theory, and in light of the widely established competitive nature of males, we hypothesize that unique and displayable rewards (trophies out of competition may trigger male generosity in competitive social environments. PRINCIPAL FINDINGS: Here, we use a controlled laboratory experiment to show that cooperation is sustained in a generosity competition with trophy rewards, but breaks down in the same environment with equally valuable but non-unique and non-displayable rewards. Further, we find that males' competition for trophies is the driving force behind treatment differences. In contrast, it appears that female competitiveness is not modulated by trophy rewards. SIGNIFICANCE: Our results suggest new approaches to promoting cooperation in human groups that, unlike punishment mechanisms, do not sacrifice efficiency. This could have important implications in any domain where voluntary compliance matters--including relations between spouses, employers and employees, market transactions, and conformity to legal standards.

Full Text Available The paper uses New Empirical Industrial Organization approach, especially Panzar-Rosse model to estimates the level of competition of the banking industry in the Czech Republic during the period 2001–2009. We apply Panzar-Rosse model to estimate H statistic for a panel of 15 banks, which represent almost 90 % of the market. This paper also measures and compares the degree of banking competition in two sub-periods, 2001–2005 and 2005–2009, in order to investigate development of the competitive structure of the Czech banking industry. We found that the market was in equilibrium during most of the estimation period, which is a necessary condition for sound evaluation of the competition level. While the market can be described as perfectly competitive in 2001–2005, the intensity of competition decreased after joining the EU in 2004 and the market can be characterized as one of monopolistic competition in 2005–2009. The monopolistic competition in the Czech banking market was also revealed if the full sample 2001–2009 is considered.

Complex Dynamics in a Triopoly Game with Multiple Delays in the Competition of Green Product Level
Si, Fengshan; Ma, Junhai
Research on the output game behavior of oligopoly has greatly advanced in recent years. But many unknowns remain, particularly the influence of consumers’ willingness to buy green products on the oligopoly output game. This paper constructs a triopoly output game model with multiple delays in the competition of green products. The influence of the parameters on the stability and complexity of the system is studied by analyzing the existence and local asymptotic stability of the equilibrium point. It is found that the system loses stability and increases complexity if delay parameters exceed a certain range. In the unstable or chaotic game market, the decisions of oligopoly will be counterproductive. It is also observed that the influence of weight and output adjustment speed on the firm itself is obviously stronger than the influence of other firms. In addition, it is important that weight and output adjustment speed cannot increase indefinitely, otherwise it will bring unnecessary losses to the firm. Finally, chaos control is realized by using the variable feedback control method. The research results of this paper can provide a reference for decision-making for the output of the game of oligopoly.

COMPETITION FOR THE MARKET AND LIBERALIZATION: THE FRENCH EXPERIENCE
Directory of Open Access Journals (Sweden)
Bruno Lassere
2014-12-01
Full Text Available Progressing from a state controlled economy to a fully liberalized market economy takes considerable efforts. Depending on the specificities of the markets and the sectors regulated, the opening of markets to competition can take different forms. Competition on the market is considered to be the traditional form of competition. Certain economic sectors, however, are not prone to this traditional form of competition, specifically in situations where natural monopolies seem to be the only viable solutions. This is where competition for the market can be a good substitute.Competition for the market implies that a bidding process is organized to select the operator, which will be allowed to serve demand on a given market for a given time. Going through this bidding process is meant to introduce market mechanisms or, in other words, ex ante competition. As such, competition for the market contributes to put competitive pressure on monopolists, which is beneficial to consumers and users not only in terms of price and service quality, but also in terms of adjustment between supply and demand and access to information.Experience has shown, however, that several factors can hinder the expected benefits derived from competition for the market. In light of these difficulties, the French Competition Authority de la concurrence has developed solutions to unleash the full potential of competition for the market.Naturally, once markets are liberalized, comes the time for regulation through enforcement actions as well as continued advocacy efforts toward government, incumbent operators and new market players.

Knowledge management performance methodology regarding manufacturing organizations
Istrate, C.; Herghiligiu, I. V.
2016-08-01
The current business situation is extremely complicated. Business must adapt to the changes in order (a) to survive on the increasingly dynamic markets, (b) to meet customers’ new request for complex, customized and innovative products. In modern manufacturing organizations it can be seen a substantial improvement regarding the management of knowledge. This occurs due to the fact that organizations realized that knowledge and an efficient management of knowledge generates the highest value. Even it could be said that the manufacturing organizations were and are the biggest beneficiary of KM science. Knowledge management performance (KMP) evaluation in manufacturing organizations can be considered as extremely important because without measuring it, they are unable to properly assess (a) what goals, targets and activities must have continuity, (b) what must be improved and (c) what must be completed. Therefore a proper KM will generate multiple competitive advantages for organizations. This paper presents a developed methodological framework regarding the KMP importance regarding manufacturing organizations. This methodological framework was developed using as research methods: bibliographical research and a panel of specialists. The purpose of this paper is to improve the evaluation process of KMP and to provide a viable tool for manufacturing organizations managers.

Competition, salinity, and clonal growth in native and introduced irises.
Mopper, Susan; Wiens, Karen C; Goranova, Greta A
2016-09-01
Iris pseudacorus spread rapidly into North America after introduction from Europe in the 1800s and now co-occurs with native I. hexagona in freshwater Louisiana wetlands. Native irises support and interact with multiple trophic levels, whereas I. pseudacorus is classified an invasive pest because it grows aggressively, reduces biodiversity, and displaces native vegetation. Salinity levels are increasing in coastal wetlands worldwide. We examined how salt-stress affects competitive interactions between these conspecifics. We established a three-way full-factorial common-garden experiment that included species (I. pseudacorus, I. hexagona), competition (no competition, intraspecific competition, and interspecific competition), and salinity (0, 4, 8 parts per thousand NaCl), with six replicates per treatment. After 18 mo, Iris pseudacorus produced much more biomass than the native species did (F1, 92 = 71.5, P Interspecific competition did not affect the introduced iris, but biomass of the native was strongly reduced (competition × species interaction: F2, 95 = 76.7, P = 0.002). Salinity significantly reduced biomass of both species (F2, 92 = 21.8, P competitive advantage over the native, regardless of environmental salinity levels. Based on patterns in clonal reproduction, the introduced iris could potentially threaten native iris populations. We are currently investigating seed production and mortality during competition and stress because both clonal and sexual reproduction must be considered when predicting long-term population dynamics. © 2016 Botanical Society of America.
Debiasing egocentrism and optimism biases in repeated competitions

Full Text Available When judging their likelihood of success in competitive tasks, people tend to be overoptimistic for easy tasks and overpessimistic for hard tasks (the shared circumstance effect; SCE. Previous research has shown that feedback and experience from repeated-play competitions has a limited impact on SCEs. However, in this paper, we suggest that competitive situations, in which the shared difficulty or easiness of the task is more transparent, will be more amenable to debiasing via repeated play. Pairs of participants competed in, made predictions about, and received feedback on, multiple rounds of a throwing task involving both easy- and hard-to-aim objects. Participants initially showed robust SCEs, but they also showed a significant reduction in bias after only one round of feedback. These and other results support a more positive view (than suggested from past research on the potential for SCEs to be debiased through outcome feedback.

Full Text Available Involvement of European Union plays an important role in the areas of education and training equally. The member states are responsible for organizing and operating their education and training systems themselves. And, EU policy is aimed at supporting the efforts of member states and trying to find solutions for the common challenges which appear. In order to make our future sustainable maximally; the key to it lies in education. The highly qualified workforce is the key to development, advancement and innovation of the world. Nowadays, the competitiveness of higher education institutions has become more and more appreciated in the national economy. In recent years, the frameworks of operation of higher education systems have gone through a total transformation. The number of applying students is continuously decreasing in some European countries therefore only those institutions can “survive” this shortfall, which are able to minimize the loss of the number of students. In this process, the factors forming the competitiveness of these budgetary institutions play an important role from the point of view of survival. The more competitive a higher education institution is, the greater the chance is that the students would like to continue their studies there and thus this institution will have a greater chance for the survival in the future, compared to ones lagging behind in the competition. Aim of our treatise prepared is to present the current situation and main data of the EU higher education and we examine the performance of higher education: to what extent it fulfils the strategy for smart, sustainable and inclusive growth which is worded in the framework of Europe 2020 programme. The treatise is based on analysis of statistical data.

Full Text Available The objective of this paper is to analyze the association between marketing resources and corporate competitiveness. Empirical data were collected by a survey of 300 domestic organizations and the results were compared to the ones of a similar research conducted five years before. We have found that all the marketing resources investigated have a significant effect on marketing performance. Among them the most marketing-related resource dimension, called market management, excels regarding the strength of the association with competitiveness. Clusters of companies were formulated and analyzed. A small group of the companies investigated (12% managed to advance in the development and possession of marketing resources whilst maintaining competitive product supply and price. The proportion of successful companies among them is highly significant.

Full Text Available This paper is purely theoretical, having as starting points both existing information in the literature and their correlations. The text does not have a generalized, but represent personal opinions and conclusions. Critically analyzing the definitions given in the literature the term "strategic human resource management ", we found that most of them referred to the involvement he has it in obtaining competitive advantage of an organization. Also, starting from the study of different approaches to strategic management of human resources, we can see that besides the role that obtain competitive advantage, it supports innovative activity of a company. So we can talk about a link between strategic management of human resources, innovation and achieving competitive advantage. By presenting how strategic human resource management can be implemented in an organization, its high performance practices for human resources, it demonstrates that they support employee creativity through free expression of ideas, involvement in decision making, resulting in the way to innovation and thus to obtain competitive advantage. This work, theoretical, was completed by a presentation that show the interdependencies that exist between the three think elements: strategic human resources management, innovation, competitive advantage.

Histones are intracellular proteins that are structural elements of nuclear chromatin and regulate gene transcription. However, the extracellular histones released in response to bacterial challenges have been identified as mediators contributing to endothelial dysfunction, organ failure, and death during sepsis. In the present study, the adsorption of histones as well as plasma proteins (α1-acid glycoprotein (AGP), albumin, and γ-globulin) on alginic acid, pectin, dextran, and chitosan was examined in order to evaluate the potential of natural polysaccharides as therapeutic agents for multiple organ failure in sepsis. Alginic acid and pectin strongly adsorbed histones, whereas the adsorption abilities of dextran and chitosan toward histones were very low or negligible. Among the natural polysaccharides examined, only alginic acid did not adsorb any of the plasma proteins. These results demonstrated that alginic acid strongly adsorbed histones, but not plasma proteins; therefore, it has potential as a candidate drug for the treatment of multiple organ failure in sepsis.

Environmental structure and competitive scoring advantages in team competitions
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.

Full Text Available Contemporary organizations operate in dynamic, complex markets. One of the directions of their development is the increase of competitiveness level. This level must be based on factors for building competitive advantage, clear for the given organization, or, in a broader sense, based on general conditions for the increase of competitiveness. One of these directions could be innovation, which would lead to development and the gaining of new markets. Being innovative depends on the ideas and their implementation. This in turn depends on knowledge, primarily tacit knowledge, which is associated with the employees. To identify it, and next lead to its diffusion and application, the organization must learn the dependencies in which employees function, and match to them certain actions that would result in the increase of innovation potential. The learning of the actual relations is possible with the application of the organizational network analysis. This paper presents an example of applying organizational networks in an enterprise, on the basis of a conducted study. The results suggest that such tools are useful and that the organization, after the interventions it launched, achieves in the analyzed area a level of competitiveness higher than in other areas.

Microcystins are the most commonly occurring cyanotoxins, and have been extensively studied across the globe. In the present study, a strongly basic anion exchange resin was employed to investigate the removal of Microcystin-LR (MCLR), one of the most toxic microcystin variants. Factors influencing the uptake behavior included the MCLR and resin concentrations, resin dosage, and natural organic matter (NOM) characteristics, specifically, the charge density and molecular weight distribution of source water NOM. Equivalent background concentration (EBC) was employed to evaluate the competitive uptake between NOM and MCLR. The experimental data were compared with different mathematical and physical models and pore diffusion was determined as the rate-limiting step. The resin dose/solute concentration ratio played a key role in the MCLR uptake process and MCLR removal was attributed primarily to electrostatic attractions. Charge density and molecular weight distribution of the background NOM fractions played a major role in MCLR removal at lower resin dosages (200 mg/L ∼ 1 mL/L and below), where a competitive uptake was observed due to the limited exchange sites. Further, evidences of pore blockage and site reduction were also observed in the presence of humics and larger molecular weight organic fractions, where a four-fold reduction in the MCLR uptake was observed. Comparable results were obtained for laboratory studies on synthetic laboratory water and surface water under similar conditions. Given their excellent performance and low cost, anion exchange resins are expected to present promising potentials for applications involving the removal of removal of algal toxins and NOM from surface waters.

Many of my family, friends, and colleagues would describe me as competitive and that at times I overuse this skill with a win-at-all-costs attitude. I would tend to agree. I love to win. Yet for me winning is not about me, it is as our coaches suggest, about others. I was recently asked by a new clinical leader if I missed taking care of patients. Without thinking, my response was that I take part in the care (add value) of every patient as a leader. Every decision we make as leaders (coaches) impacts many others regardless of the magnitude of our decision and, at times, our direct involvement. Operational excellence, in any field, is about winning. We all have different definitions of winning, defined by the strategic vision for our organizations. An organization's managers, supervisors, and employees all play an important role in the team to achieve the vision of the organization. As some elite coaches have suggested, winning starts with each of us being our best. Today's environment requires consistent change. Yet many in the radiology field change the wrong things for the wrong reasons. Many organizations and individuals look for instant gratification, specifically in this new era of competitiveness. Many evaluate what their competitors are doing in the market, what cars their neighbors are buying, or become jealous over a friend's success. Focusing on others and not improving yourself takes your focus away from what is important-you and the team you lead. Keeping your focus on your operations and what you can control may very well help you coach a winning team.
AN IT CONTEST ENVIRONMENT FOR ACTIVE LEARNING THROUGH COMPETITIONS

Full Text Available Because of constantly evolving developments in computing, students often feel that they need to study a great deal of materials passively. One way of developing a natural interest in computing is to organize group-based competitions. This paper describes the design and implementation of an online system for a “Millionaire”-type competition that was adopted for a computer literacy course. The students competed with each other in groups to win the game. Each group was required to discuss the answers, contributing to better learning. The project provided students with an environment of mutual respect and open communication. Students consequently evaluated the competition regarding enhancement of knowledge and learning through team efforts, providing positive feedback.
Interspecific competition in plants: how well do current methods answer fundamental questions?
Connolly, J; Wayne, P; Bazzaz, F A
2001-02-01
Accurately quantifying and interpreting the processes and outcomes of competition among plants is essential for evaluating theories of plant community organization and evolution. We argue that many current experimental approaches to quantifying competitive interactions introduce size bias, which may significantly impact the quantitative and qualitative conclusions drawn from studies. Size bias generally arises when estimates of competitive ability are erroneously influenced by the initial size of competing individuals. We employ a series of quantitative thought experiments to demonstrate the potential for size bias in analysis of four traditional experimental designs (pairwise, replacement series, additive series, and response surfaces) either when only final measurements are available or when both initial and final measurements are collected. We distinguish three questions relevant to describing competitive interactions: Which species dominates? Which species gains? and How do species affect each other? The choice of experimental design and measurements greatly influences the scope of inference permitted. Conditions under which the latter two questions can give biased information are tabulated. We outline a new approach to characterizing competition that avoids size bias and that improves the concordance between research question and experimental design. The implications of the choice of size metrics used to quantify both the initial state and the responses of elements in interspecific mixtures are discussed. The relevance of size bias in competition studies with organisms other than plants is also discussed.

Many methods in freshwater biomonitoring tend to be restricted to a few levels of biological organization, limiting the potential spectrum of measurable of cause-effect responses to different anthropogenic impacts. We combined distinct organisational levels, covering biological biomarkers (histopathological and biochemical reactions in liver and fish gills), community based bioindicators (fish guilds, invertebrate metrics/traits and chironomid pupal exuviae) and ecosystem functional indicators (decomposition rates) to assess ecological status at designated Water Framework Directive monitoring sites, covering a gradient of human impact across several rivers in northern Portugal. We used Random Forest to rank the variables that contributed more significantly to successfully predict the different classes of ecological status and also to provide specific cut levels to discriminate each WFD class based on reference condition. A total of 59 Biological Quality Elements and functional indicators were determined using this procedure and subsequently applied to develop the integrated Multiple Ecological Level Index (MELI Index), a potentially powerful bioassessment tool.

Encounter competition is interference competition in which animals directly contend for resources. Ecological theory predicts the trait that determines the resource holding potential (RHP), and hence the winner of encounter competition, is most often body size or mass. The difficulties of observing encounter competition in complex organisms in natural environments, however, has limited opportunities to test this theory across diverse species. We studied the outcome of encounter competition contests among mesocarnivores at deer carcasses in California to determine the most important variables for winning these contests. We found some support for current theory in that body mass is important in determining the winner of encounter competition, but we found that other factors including hunger and species-specific traits were also important. In particular, our top models were "strength and hunger" and "size and hunger," with models emphasizing the complexity of variables influencing outcomes of encounter competition. In addition, our wins above predicted (WAP) statistic suggests that an important aspect that determines the winner of encounter competition is species-specific advantages that increase their RHP, as bobcats (Lynx rufus) and spotted skunks (Spilogale gracilis) won more often than predicted based on mass. In complex organisms, such as mesocarnivores, species-specific adaptations, including strategic behaviors, aggressiveness, and weapons, contribute to competitive advantages and may allow certain species to take control or defend resources better than others. Our results help explain how interspecific competition shapes the occurrence patterns of species in ecological communities. © 2016 by the Ecological Society of America.

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

Full Text Available Photovoltaic (PV power generation is embedded in a globally competitive environment. This characteristic forces PV power plants to perform most processes relevant for their competitiveness with maximum efficiency. From managers’ point of view, the evaluation of solar energy performance from installed plants is justified to indicate their level of organizational competitiveness, which supports the decision-making process. This manuscript purposes a computational tool that graphically presents the level of competitiveness of PV power plants units based on performance indicators. This tool was developed by using the Key Performance Indicators (KPIs concept, which represents a set of measures focusing on the most critical aspects for the success of the organizations. The KPIs encompass four Fundamental Viewpoints (FV: Strategic Alliances, Solar Energy Monitoring, Management and Strategic Processes, and Power Generation Innovations. These four FVs were deployed on 26 Critical Success Factors (CSFs and 39 KPIs. Sequentially, the tool was applied in four solar generation plants, where three presented an organizational competitiveness global level “potentially competitive”. The proposed computational tool allows managers to assess the degree of organization competitiveness as well as aid in prospecting of future scenarios and decision-making.

Film competitions can be a helpful method to understand issues of quality in health films. In this paper, we describe the development and use of explicit quality criteria to identify the 'best' films for the first ever international public health film competition. A film selection committee encompassing a range of stakeholders was compiled. The committee drew up 10 explicit quality criteria to judge films drawing upon other film festival's selection criteria. These criteria were then applied to a broad range of health-related films entered into a film competition to select the 'best' film to screen. Eighty-four films from 20 different countries were submitted to the public health film competition. The originality of the subject covered by the film, the public health importance of the issue and story-telling approach in the film were found to be the most discriminatory criteria to select films. Selection of health films for festivals can be undertaken using explicit quality criteria. There are a number of advantages to such an approach; however, explicit selection involves a large commitment of resources from film festival organizers and there is further research required to test the validity of the quality criteria applied to health-related films.

Full Text Available The idea of European unity dates back to antiquity, the time when the Roman Empire alsopursued such a goal. Attempts to unify European countries have appeared constantly in history, but theirsuccessful culmination crystallized only after the Second World War.Basically, the two wars have led to the downfall of Europe and the loss of its centenary political andmilitary position. The experience of these wars has led the states to initiate a defense mechanism of peace,security and international cooperation - resulted in creating an organization of universal jurisdiction -TheLeague of Nations. However, the successor of this organization, The United Nations - was one thatmanaged thorough its collective security system represented by the Security Council, to ensure andmaintain universal / global peace until now (Stelian Scăunaş, 2005.The creation of the European Union is based on four founding treaties: The Treaty establishingThe European Coal and Steel Community (ECSC - adopted in Paris on April 18, 1951, entered into forcein 1952 - treaty concluded for a period of 50 years and that has terminated in 2002, The Treatyestablishing the European Economic Community (EEC, The Treaty establishing the European AtomicEnergy Community (EAEC or EURATOM, both signed in Rome on March 25, 1947 and entered into forcein 1958 as the Treaties of Rome, and The Treaty on the European Union, which was adopted at Maastrichton 7th of February 1992 and entered into force in 1993.

Full Text Available Research Question: The existence of organizations in competitive markets depends on their ability to stay competitive. Quality departments play a key role in organizing and ensuring quality. Purpose: The survey tries to determine the correlation between the existence of quality departments and organization of quality in organizations; our hypothesis is that the correlation is very strong. Method: A survey was performed in 484 large and medium-sized organizations in Slovenia to examine the situation in this area. Pearson's χ2-test was used for data processing and results presented in a contingency table. Results: Organizations with quality departments more frequently also have certificate ISO 9001 in comparison with organizations without quality departments. Also these organizations more frequently have supplier-relations teams, monitoring system of suppliers' progress and excellence centers. In short, the quality in these organizations is organized on a higher level than in organizations without quality departments. Organization: The role of quality department is important for organizations. The findings of the research are important for decision making in organizations. Society: Each organization contributes to efficiency and effectiveness of a nation. The organizational level of the nation can be measured by number of certificates per capita. Originality: The research is unique because of the research model and method applied. Limitations/Future Research: The research is limited to large and medium-sized organizations in Slovenia.

Common mycelial networks impact competition in an invasive grass.
Workman, Rachael E; Cruzan, Mitchell B
2016-06-01
Mycorrhizal hyphal complexes can connect multiple host plants to form common mycelial networks (CMNs) that may affect plant competitive outcomes and community composition through differential resource allocation. The impacts of CMN interactions on invasive plants are not well understood and could be crucial to the understanding of invasive plant establishment and success. We grew the invasive grass Brachypodium sylvaticum in intra- and interspecific pairings with native grass Bromus vulgaris in a greenhouse and controlled for the effects of CMN and root interactions by manipulating the belowground separation between competitors. Comparison of plant growth in pots that allowed CMN interactions and excluded root competition and vice versa, or both, allowed us to delineate the effects of network formation and root competition on invasive plant establishment and performance. Brachypodium sylvaticum grown in pots allowing for only hyphal interactions, but no root competition, displayed superior growth compared with conspecifics in other treatments. Invasive performance was poorest when pairs were not separated by a barrier. Shoot nitrogen content in B. sylvaticum was higher in mycorrhizal plants only when connections were allowed between competitors. Our results indicate that the presence of CMN networks can have positive effects on B. sylvaticum establishment and nutrient status, which may affect plant competition and invasion success. © 2016 Botanical Society of America.

Full Text Available A competition is a contest between individuals or groups. The gain is often an award or recognition, which serves as a catalyst to motivate individuals to put forth their very best. Such events for recognition and success are part of many International Society for Computational Biology (ISCB Student Council Regional Student Groups (RSGs activities. These include a popular science article contest, a Wikipedia article competition, travel grants, poster and oral presentation awards during conferences, and quizzes at social events. Organizing competitions is no different than any other event; they require a lot of hard work to be successful. Each event gives remarkable organizational and social experience for students running it, while at the same time the participants of the competitions are rewarded by prizes and recognition. It gives everybody involved an opportunity to demonstrate their extraordinary talents and skills. Competitions are unique because they bring out both the best and worst in people.

Multiple infections of the same host by different strains of the same microparasite species are believed to play a crucial role during the evolution of parasite virulence. We investigated the role of specificity, relative virulence and relative dose in determining the competitive outcome of multiple infections in the Daphnia magna-Pasteuria ramosa host-parasite system. We found that infections by P. ramosa clones (single genotype) were less virulent and produced more spores than infections by P. ramosa isolates (possibly containing multiple genotypes). We also found that two similarly virulent isolates of P. ramosa differed considerably in their within-host competitiveness and their effects on host offspring production when faced with coinfecting P. ramosa isolates and clones. Although the relative virulence of a P. ramosa isolate/clone appears to be a good indicator of its competitiveness during multiple infections, the relative dose may alter the competitive outcome. Moreover, spore counts on day 20 post-infection indicate that the competitive outcome is largely decided early in the parasite's growth phase, possibly mediated by direct interference or apparent competition. Our results emphasize the importance of epidemiology as well as of various parasite traits in determining the outcome of within-host competition. Incorporating realistic epidemiological and ecological conditions when testing theoretical models of multiple infections, as well as using a wider range of host and parasite genotypes, will enable us to better understand the course of virulence evolution.

Perception of coaching behaviors, coping, and achievement in a sport competition.
Nicolas, Michel; Gaudreau, Patrick; Franche, Veronique
2011-06-01
This study examined the relationship between perceived coaching behaviors, coping strategies during a sport competition, and sport achievement. A prospective design was used in which 80 athletes from individual sports completed measures of perceived coaching behaviors two days before a competition (Time 1) and measures of coping and sport achievement within three hours after a sport competition (Time 2). As expected, results of multiple regressions indicated that supportive coaching was a positive predictor of task-oriented coping and sport achievement whereas unsupportive coaching was a positive predictor of disengagement-oriented coping. Both types of coping were significantly associated with sport achievement. Task-oriented coping was a significant partial mediator in the relation between supportive coaching and sport achievement. This study, which contributes to both the coaching and coping literatures, highlights the role of supportive coaching behaviors in the initiation of effective stress management during sport competitions.

Full Text Available Abstract Background Sequestration of parasitized red blood cells in the microvasculature of major organs involves a sequence of events that is believed to contribute to the pathogenesis of severe falciparum malaria. Plasmodium falciparum infections are commonly composed of multiple subpopulations of parasites with varied adhesive properties. A key question is: do these subpopulations compete for adhesion to endothelium? This study investigated whether, in a laboratory model of cytoadherence, there is competition in binding to endothelium between pRBC infected with P. falciparum of variant adhesive phenotypes, particularly under flow conditions. Methods Four different P. falciparum isolates, of known adherence phenotypes, were matched in pairs, mixed in different proportions and allowed to bind to cultured human endothelium. Using in vitro competitive static and flow-based adhesion assays, that allow simultaneous testing of the adhesive properties of two different parasite lines, adherence levels of paired P. falciparum isolates were quantified and analysed using either non-parametric Wilcoxon's paired signed rank test or Student paired test. Results Study findings show that P. falciparum parasite lines show marked differences in the efficiency of adhesion to endothelium. Conclusion Plasmodium falciparum variants will compete for adhesion to endothelia and variants can be ranked by their efficiency of binding. These findings suggest that variants from a mixed infection will not show uniform cytoadherence and so may vary in their ability to cause disease.

Full Text Available Nowadays, social marketing practices represent an important part of people’s lives. Consumers’ understanding of the need for change has become the top priority for social organizations worldwide. As a result, the number of social marketing programs has increased, making people reflect more on their behaviors and on the need to take action. Competition in social marketing can bring many benefits. The more programs initiated, the more people will start to involve in society’s problems, hereby contributing to beneficial causes. However, social organizations are in the search for competitive advantages to differentiate them on the market. This paper aims to present the role of online communication in driving competitive advantage for social organizations. Using the structural equation model, the paper describes the relations between four characteristics of the online communication: credibility, attractiveness, persuasion and promotion and then presents the correlations between these variables and website competitiveness. The resulting model shows that owning a competitive advantage in social marketing can bring many advantages to both the non-profit organization and the consumer. Therefore, the online environment can be considered a good solution for better serving consumers’ social needs. Its contribution is significant especially in programs for children and adolescents, since teenagers spend more time on the Internet than adults and are more open to using the online channels of communication. In conclusion, this article opens new opportunities for social marketers to address society’s problems and supports the integration of the online communication tools in the competition strategy.
The relation between proactive environmental strategies and competitive advantage
Butnariu, A.; Avasilcăi, S.
2015-11-01
There are two distinct orientations of the environmental management that companies may adopt: the model of compliance and the strategic model. The strategic model treats environmental expenses as investments that will lead to competitive advantage for the company. Nevertheless, there are few scientific works that prove the relation between corporate environmental investments and competitive advantage. Thereby, in order to bring clarifications about the profound implications of environmental investments, in the first stage of our research we have proposed the hypothesis that the environmental investments would probably lead to competitive advantage by creating capabilities that are mediators of this relation. In the second stage we have tested this hypothesis, using the research method of survey. A questionnaire was sent to managers in textile Romanian industry, and 109 answers were received. The data was analysed using the linear multiple regression method and the results confirm our hypothesis.

To ensure the highest technical performance, speed, safety, excellent control and to improve competitive performance, a successful regulation of competitive anxiety is necessary. Therefore, it seems crucial to identify factors influencing competitive anxiety of adolescent athletes. Research suggests that people reporting high quality of life are more capable to cope with stressful and challenging situations than others. The aim of this study was to investigate the impact of quality of life, the involvement of parents in sports career and coach's leadership behaviour on competitive anxiety in Winter Youth Olympic Games participants. During the first Winter Youth Olympic Games 2012 in Innsbruck/Austria, 662 (316 women) participants completed questionnaires and single items to assess quality of life, coach's leadership behaviour, parental involvement in sports career and competitive anxiety. Multiple regression analysis revealed positive influences of high quality of life and useful coach instruction on competitive anxiety. The relationship between quality of life, coach behaviour and competitive anxiety in young elite athletes competing at the first Winter Youth Olympic Games should be considered in long-term programmes for reducing competitive stress.

We describe a novel instrument which is capable of measuring the uptake of radioligand in human organs in vivo with the administration of very small doses of positron-emitting radioligands. This technique readily detects the displacement or reduced uptake of radioligand when a competitive agonist or antagonist is administered. This system provides no tomographic information, but the small radioactive doses involved mean that investigations can be repeated at regular intervals and that female volunteers can also participate. We administered [(11) C]flumazenil, [(11)C]diprenorphine, [(11)C]meta -hydroxyephedrine (MHED) and [(11)C]RTI 55 to healthy male volunteers and performed control, pre-loading and displacement experiments. These demonstrate the feasibility of using this technique to investigate benzodiazepine and opiate receptor occupancy, as well as occupancy at dopamine, noradrenaline and serotonin (5-HT) re-uptake sites. This method is likely to be useful in pharmacokinetic/pharmacodynamic experiments, in drug development and discovery and in the development of novel imaging radioligands.

Full Text Available After the globalization of market the micro, small and medium enterprises (MSMEs got numerous opportunities to work in integration with large-scale organizations. Competitive advantage plays a significant role in deciding how organizations can exploit theses opportunities. So, the aim of this paper is to measure the competitive advantage of MSMEs based upon the Porter's diamond model framework. A welldesigned questionnaire is used to collect data about the various determinants of the model. Based upon the frequency of responses, percent point score (PPS of each casual variable was calculated. By reviewing the result of this study, it is observed that competitiveness among MSME's sectors is mostly affected by market value. As is indicated by maximum PPS score e.g. 68%, followed by highly educated personnel, production and process technology (62%, further study results indicate that there is a need to increase clusters i.e. related and supported industries as depicted by low score (PPS=49%.

Multiple-Transportable Carbohydrate Effect on Long-Distance Triathlon Performance.
Rowlands, David S; Houltham, Stuart D
2017-08-01
The ingestion of multiple (2:1 glucose-fructose) transportable carbohydrate in beverages at high rates (>78 g·h) during endurance exercise enhances exogenous carbohydrate oxidation, fluid absorption, gut comfort, and performance relative to glucose alone. However, during long-distance endurance competition, athletes prefer a solid-gel-drink format, and the effect size of multiple-transportable carbohydrate is unknown. This study aimed to determine the effect of multiple-transportable carbohydrate on triathlon competition performance when ingested within bars, gels, and drinks. A double-blind randomized controlled trial was conducted within two national-body sanctioned half-ironman triathlon races held 3 wk apart in 74 well-trained male triathletes (18-60 yr; >2 yr competition experience). Carbohydrate comprising glucose/maltodextrin-fructose (2:1 ratio) or standard isocaloric carbohydrate (glucose/maltodextrin only) was ingested before (94 g) and during the cycle (2.5 g·km) and run (7.8 g·km) sections, averaging 78.6 ± 6.6 g·h, partitioned to bars (25%), gels (35%), and drink (40%). Postrace, 0- to 10-unit Likert-type scales were completed to assess gut comfort and energy. The trial returned low dropout rate (9%), high compliance, and sensitivity (typical error 2.2%). The effect of multiple-transportable carbohydrate on performance time was -0.53% (95% confidence interval = -1.30% to 0.24%; small benefit threshold = -0.54%), with likelihood-based risk analysis supporting adoption (benefit-harm ratio = 48.9%:0.3%; odds ratio = 285:1). Covariate adjustments for preexercise body weight and heat stress had negligible impact performance. Multiple-transportable carbohydrate possibly lowered nausea during the swim and bike; otherwise, effects on gut comfort and perceived energy were negligible. Multiple-transportable (2:1 maltodextrin/glucose-fructose) compared with single-transportable carbohydrate ingested in differing format provided a small benefit to long
Dakwah, competition for authority, and development

Full Text Available Da`wah – usually spelt dakwah in Indonesian – has been an important aspect of Islam from its very birth. Since the late nineteenth century, however, as a result of political and social transformations it has taken new forms. In one form or others, da`wah has been practised by a large variety of Islamic movements and organizations. Although complementary to each other in certain cases, in others their relations have rather been characterized by competition for authority and power, not only between various da`wah organizations, but also, through these organizations, between regimes, categories of religious and social leaders, and social categories of Muslims. For this reason, da`wah has had important dimensions beyond the domain of religion proper. Moreover, da`wah has been connected to political and social causes such as the struggle against communism and Christianity – sometimes emulating them in certain respects – and community development. Quite a few da`wah initiatives, state-sponsored or non-governmental, have taken transnational scopes. Indonesian dakwah has shared most of the above features. This article, analyzing dakwah in Indonesia, confirms their existence and adds to their understanding. It substantiates theories on the objectification of Islam in modern societies: the spread of mass education has led to the fragmentation of religious understanding, which has stimulated a fierce competition for religious authority and the control of religious institutions and organizations. Just as in many other Muslim-majority countries, in Indonesia the state has played a prominent role in the development of mass education, the ensuing competition for religious authority, as well as the functionalization of religion. As was the case elsewhere, in Indonesia dakwah has had important dimensions beyond the religious domain. On the other hand, Indonesian dakwah has shown a number of particularities. In order to illustrate the combination of
Self-esteem and injury in competitive field hockey players.
Kolt, G S; Roberts, P D
1998-08-01
A volunteer sample of 50 competitive field hockey players completed the Coopersmith Self-esteem Inventory at pre- and postseason and prospectively collected injury data over a 20-wk. season. Multiple regression analysis showed no relationship between scores on Self-esteem and the number of injuries, the participation time affected due to injury, and sex of players. Further multiple regression analysis showed that frequency of the more severe injuries significantly predicted scores on Self-esteem. This finding can be interpreted as evidence of the relationship between low self-esteem and injury in sport.
The Resilient Economy: Integrating Competitiveness and Security

Globalization, technological complexity, interdependence, terrorism, climate and energy volatility, and pandemic potential are increasing the level of risk that societies and organizations now face. Risks also are increasingly interrelated; disruptions in one area can cascade in multiple directions. The ability to manage emerging risks, anticipate the interactions between different types of risk, and bounce back from disruption will be a competitive differentiator for companies and countries alike in the 21st century. What Policymakers Should Know The national objective is not just homeland protection, but economic resilience: the ability to mitigate and recover quickly from disruption. Businesses must root the case for investment in resilience strategies to manage a spectrum of risks, not just catastrophic ones. Making a business case for investment in defenses against low-probability events (even those with high impact) is difficult. However, making a business case for investments that assure business continuity and shareholder value is not a heavy lift. There are an infinite number of disruption scenarios, but only a finite number of outcomes. Leading organizations do not manage specific scenarios, rather they create the agility and flexibility to cope with turbulent situations. The investments and contingency plans these leading companies make to manage a spectrum of risk create a capability to respond to high-impact disasters as well. Government regulations tend to stovepipe different types of risk, which impedes companies abilities to manage risk in an integrated way. Policies to strengthen risk management capabilities would serve both security and competitiveness goals. What CEOs and Boards Should Know Operational risks are growing rapidly and outpacing many companies abilities to manage them. Corporate leadership has historically viewed operational risk management as a back office control function. But managing operational risks increasingly affects real
Impurity Induced Phase Competition and Supersolidity
Karmakar, Madhuparna; Ganesh, R.
2017-12-01
Several material families show competition between superconductivity and other orders. When such competition is driven by doping, it invariably involves spatial inhomogeneities which can seed competing orders. We study impurity-induced charge order in the attractive Hubbard model, a prototypical model for competition between superconductivity and charge density wave order. We show that a single impurity induces a charge-ordered texture over a length scale set by the energy cost of the competing phase. Our results are consistent with a strong-coupling field theory proposed earlier in which superconducting and charge order parameters form components of an SO(3) vector field. To discuss the effects of multiple impurities, we focus on two cases: correlated and random distributions. In the correlated case, the CDW puddles around each impurity overlap coherently leading to a "supersolid" phase with coexisting pairing and charge order. In contrast, a random distribution of impurities does not lead to coherent CDW formation. We argue that the energy lowering from coherent ordering can have a feedback effect, driving correlations between impurities. This can be understood as arising from an RKKY-like interaction, mediated by impurity textures. We discuss implications for charge order in the cuprates and doped CDW materials such as NbSe2.

ALF patients/animals also have high levels of circulating histones, which might be the major mediators of systemic inflammation in patients with ALF. Extracellular histones kill endothelial cells and elicit immunostimulatory effect to induce multiple organ injuries. Neutralization of histones can attenuate acute liver, lung, and brain injuries. In conclusion, HMGB1 and histones play a significant role in inducing systemic inflammation and MOF in ALF.

1997-11-01
With particular reference to the recently deregulated and market-based electricity industries in Norway, the UK and elsewhere the report analyses oligopoly entry and capacity investment decisions as a non-cooperative game in a decentralized electricity market. A two-stage game is considered, with multiple capacity types and uncertain demand, in which capacity decisions are made prior to spot-market, or price competition. Equilibrium outcomes for different pricing mechanisms or regulatory regimes are analysed. The following questions are dealt with in particular: Will industry capacity be sufficient to ensure adequate supply security? Does imperfect competition in the spot-market lead to an inefficient mix of base-load and peak-load technologies? How do different regulatory policies affect the market outcomes? 24 refs., 2 figs., 1 tab.

Gut BT plays a critical role in triggering/inducing systemic inflammation/sepsis in critical illness, and profound systemic inflammatory response syndrome (SIRS can lead to multiple organ dysfunction syndrome (MODS during SAP, and systemic inflammation with multiorgan dysfunction is the cause of death in experimental SAP. Therefore, HMGB1 is an important factor that links gut BT and systemic inflammation. Furthermore, HMGB1 significantly contributes to multiple organ injuries. The SAP patients also have significantly increased circulating histones and cell-free DNAs levels, which can reflect the disease severity and contribute to multiple organ injuries in SAP. Hepatic Kupffer cells (KCs are the predominant source of circulating inflammatory cytokines in SAP, and new evidence indicates that hepatocyte is another important source of circulating HMGB1 in SAP; therefore, treating the liver injury is important in SAP.

Full Text Available The adoption of Information and Communication Technologies (ICT in organizations favors business competitiveness. This article presents teleworking as a hiring mechanism through the use of ICT and the need to define the competencies related to a teleworker’s activities. The research was carried out with 114 entrepreneurs of the footwear sector in Bucaramanga, Colombia to ascertain their perceptions on the adoption of this work modality. The results reflect that hiring teleworkers will require establishing trust and developing skills that go beyond their computer knowledge. Entrepreneurs present evidence that teleworkers must be responsible, creative, innovative, compliant with their duty, and develop the competencies related to communication, time management, and literacy to improve business competitiveness.

Alterations to multisensory and unisensory integration by stimulus competition.
Pluta, Scott R; Rowland, Benjamin A; Stanford, Terrence R; Stein, Barry E
2011-12-01
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.

The formation of stars by gravitational collapse rather than competitive accretion
Krumholz, Mark R.; McKee, Christopher F.; Klein, Richard I.
2005-11-01
There are two dominant models of how stars form. Under gravitational collapse, star-forming molecular clumps, of typically hundreds to thousands of solar masses (Msolar), fragment into gaseous cores that subsequently collapse to make individual stars or small multiple systems. In contrast, competitive accretion theory suggests that at birth all stars are much smaller than the typical stellar mass (~0.5Msolar), and that final stellar masses are determined by the subsequent accretion of unbound gas from the clump. Competitive accretion models interpret brown dwarfs and free-floating planets as protostars ejected from star-forming clumps before they have accreted much mass; key predictions of this model are that such objects should lack disks, have high velocity dispersions, form more frequently in denser clumps, and that the mean stellar mass should vary within the Galaxy. Here we derive the rate of competitive accretion as a function of the star-forming environment, based partly on simulation, and determine in what types of environments competitive accretion can occur. We show that no observed star-forming region can undergo significant competitive accretion, and that the simulations that show competitive accretion do so because the assumed properties differ from those determined by observation. Our result shows that stars form by gravitational collapse, and explains why observations have failed to confirm predictions of the competitive accretion model.
Unbundled infrastructure firms: Competition and continuing regulation
Hogendorn, Christiaan Paul
Unbundled infrastructure firms provide conduits for electricity transmission, residential communications, etc. but are vertically disintegrated from "content" functions such as electricity generation or world-wide-web pages. These conduits are being deregulated, and this dissertation examines whether the deregulated conduits will behave in an efficient and competitive manner. The dissertation presents three essays, each of which develops a theoretical model of the behavior of conduit firms in a market environment. The first essay considers the prospects for competition between multiple conduits in the emerging market for broadband (high-speed) residential Internet access. It finds that such competition is likely to emerge as demand for these services increase. The second essay shows how a monopoly electricity or natural gas transmission conduit can facilitate collusion between suppliers of the good. It shows that this is an inefficient effect of standard price-cap regulation. The third essay considers the supply chain of residential Internet access and evaluates proposed "open access" regulation that would allow more than one firm to serve customers over the same physical infrastructure. It shows that the amount of content available to consumers does not necessarily increase under open access.

The Aggressive Competitiveness Influence on the Retailer Company Performance

Antonio Benedito Oliveira Junior
2015-08-01
Full Text Available The aggressive competitiveness refers to the company tendency to challenge direct and intensively its competitors when entering into a market or to enhance its position outperforming its rivals. An approach about aggressive competitiveness shares the traditional view of "strength-weakness-opportunity-threat", another view consistent with the hyper-competitiveness model, and the third view follows the dynamic competitiveness line. However, researches have not yet focused either on the motivations or on the strategic guidelines before the attack or on the direct relationship between Aggressive Competitiveness (AC and Retailer Company Performance (CP through a qualitative and quantitative study. Within this context, the objective of this research was to analyze: i the impact of the AC in the retail CP; and ii the effect of company size factor (medium/large versus micro/small in this relationship. It was carried out a mixed survey in two stages. In the first it was used a qualitative approach, through multiple case study with eight companies. Then, in the second phase it was held a survey with 64 companies. The results indicate a positive and significant impact of the AC on the CP, but this impact is not different between medium and large sized enterprises versus micro/small sized companies. This research contributes theoretical and empirically to the literature about AC of retail companies, generating subsidies for managers to adopt a more aggressive attitude in the competitive dynamics of the retail market. The practical cases studied here corroborate the influence of AC on the CP. Specifically it demonstrates the AC importance for the survival and growth of the company in increasingly dynamic, turbulent and competitive markets.

2005-01-01
To investigate prospectively the type and rate of injuries sustained during amateur Muay Thai competition. Prospective cohort study collection of data following clinical examination. Amateur Muay Thai competitions in the United Kingdom organized by the International Amateur Muay Thai Federation. Amateur Muay Thai boxers. Both sexes. Lightweight to super heavyweight. There were 92 participants, 12 females and 82 males. The average age was 17.3 years, and the average previous number of bouts was 3.9. A total of 588.5 minutes of competition time was assessed during a total of 10 events. Injury rates were 1.3 injuries per 100 minutes of competition in the lightweight category, 2.25 per 100 minutes of competition in the middleweight category, 30 per 100 minutes of competition in the heavyweight category, and 2.54 per 100 minutes of competition in the super heavyweight category. Compared with other reported martial arts, the injury rates are higher in Muay Thai. The head was shown to be the most common site of injury in amateur fighters, but there was an almost complete absence of lower limb injuries, which again is at variance with reported figures for other martial arts.
Long-term in vivo imaging of multiple organs at the single cell level.

Benny J Chen
Full Text Available Two-photon microscopy has enabled the study of individual cell behavior in live animals. Many organs and tissues cannot be studied, especially longitudinally, because they are located too deep, behind bony structures or too close to the lung and heart. Here we report a novel mouse model that allows long-term single cell imaging of many organs. A wide variety of live tissues were successfully engrafted in the pinna of the mouse ear. Many of these engrafted tissues maintained the normal tissue histology. Using the heart and thymus as models, we further demonstrated that the engrafted tissues functioned as would be expected. Combining two-photon microscopy with fluorescent tracers, we successfully visualized the engrafted tissues at the single cell level in live mice over several months. Four dimensional (three-dimensional (3D plus time information of individual cells was obtained from this imaging. This model makes long-term high resolution 4D imaging of multiple organs possible.
Unusual fatal multiple-organ dysfunction and pancreatitis induced by a single wasp sting

Full Text Available Acute onset of multiple organ dysfunction syndrome (MODS is a well-known complication following multiple wasp stings. However, MODS after a single wasp sting has been rarely reported in children and acute pancreatitis have probably never been observed before. Herein we describe the case of a 12-year-old boy who had urticaria and abdominal pain after a single wasp sting. The child gradually developed MODS while his abdominal complaints were worsening. Despite aggressive supportive management, the child did not survive. Afterward, the cause of the acute abdomen was finally diagnosed as acute pancreatitis. Both MODS and pancreatitis following a single wasp sting are very unusual. Thus, although pancreatitis is rarely manifested, it should be suspected after a wasp sting if there are predominant abdominal symptoms.

Accumulation of heavy metals at elevated concentration and potential of considerable amount of the accumulated heavy metals to reach the soil system was observed from earlier studies in soakaways sediments within an infiltration facility in Tokyo, Japan. In order to understand the competitive adsorption behaviour of heavy metals Zn, Ni and Cu in soil, competitive batch adsorption experiments were carried out using single metal and binary metal combinations on soil samples representative of underlying soil and surface soil at the site. Speciation analysis of the adsorbed metals was carried out through BCR sequential extraction method. Among the metals, Cu was not affected by competition while Zn and Ni were affected by competition of coexisting metals. The parameters of fitted 'Freundlich' and 'Langmuir' isotherms indicated more intense competition in underlying soil compared to surface soil for adsorption of Zn and Ni. The speciation of adsorbed metals revealed less selectivity of Zn and Ni to soil organic matter, while dominance of organic bound fraction was observed for Cu, especially in organic rich surface soil. Compared to underlying soil, the surface soil is expected to provide greater adsorption to heavy metals as well as provide greater stability to adsorbed metals, especially for Cu.

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...

Competition improves robustness against loss of information

Full Text Available A substantial number of works aimed at modeling the receptive field properties of the primary visual cortex (V1. Their evaluation criterion is usually the similarity of the model response properties to the recorded responses from biological organisms. However, as several algorithms were able to demonstrate some degree of similarity to biological data based on the existing criteria, we focus on the robustness against loss of information in the form of occlusions as an additional constraint for better understanding the algorithmic level of early vision in the brain. We try to investigate the influence of competition mechanisms on the robustness. Therefore, we compared four methods employing different competition mechanisms, namely, independent component analysis, non-negative matrix factorization with sparseness constraint, predictive coding/biased competition, and a Hebbian neural network with lateral inhibitory connections. Each of those methods is known to be capable of developing receptive fields comparable to those of V1 simple-cells. Since measuring the robustness of methods having simple-cell like receptive fields against occlusion is difficult, we measure the robustness using the classification accuracy on the MNIST hand written digit dataset. For this we trained all methods on the training set of the MNIST hand written digits dataset and tested them on a MNIST test set with different levels of occlusions. We observe that methods which employ competitive mechanisms have higher robustness against loss of information. Also the kind of the competition mechanisms plays an important role in robustness. Global feedback inhibition as employed in predictive coding/biased competition has an advantage compared to local lateral inhibition learned by an anti-Hebb rule.
The perception of injury risk and safety in triathlon competition: an exploratory focus group study.
Gosling, Cameron McR; Donaldson, Alex; Forbes, Andrew B; Gabbe, Belinda J
2013-01-01
To explore stakeholder perceptions of triathlon competition safety and injury risk. Qualitative focus group study. Triathlon stakeholders from Melbourne, Australia. Competition organizers, coaches, and competitors of various skill levels, age, gender, and experience (n = 18). Focus groups were conducted, recorded, and transcribed for analysis. Key themes were identified using content analysis. The perceived risk of serious injury was highest for cycling. Running was most commonly linked to minor injuries. Physical and environmental factors, including course turning points, funneling of competitors into narrow sections, and the weather, were perceived as contributing to injury. Experience, skill level, feelings of vulnerability, personal awareness, club culture, and gender issues were perceived as the competitor-related factors potentially contributing to injury. The cycling mount/dismount area, cycling, and swim legs were the race sections perceived as the riskiest for competitors. Competition organizers were considered to generally have the competitors' best interest as a priority. Triathlons were acknowledged as risky activities and individual competitors accepted this risk. This study has highlighted the main risks and concerns perceived by triathlon competitors, coaches, and competition organizers, which will help identify potential, context-relevant intervention strategies to reduce injury risk.

Full Text Available Clusters, as a form of self-organization of enterprises and associated institutions, help increase levels of competitiveness of its members by inspiring competition and cooperation. The question of increasing the popularity of clusters is especially important at the present moment when creators of economical politics are focused on finding the leading multinational companies, who's involvement on Serbia's market and starting of production, with a possibility to export it, would create opportunities to take over some of their suppliers by Serbia's SMEs. The analysis of selected European clusters has shown that joining of SMEs into clusters increases their productivity, competitiveness and export capability. Dynamic development of SMEs in Serbia will not be possible without intensified efforts in overcoming the main limitations and impediments, perhaps most importantly insufficient competitiveness and quality of products, poor organization on territorial and branch levels and prolonged amounting of unpaid bills. That is why the government has a defining role to play in creating a healthy competitive ambient, because of all the factors involved on the market, often non-economical factors, as well, and often many elements and institutions, and if the government does not take proper measures it'll create a bad business ambient in which SMEs can't use their full potential.

There are many non-mutually exclusive mechanisms for exotic invasions but few studies have concurrently tested more than one hypothesis for the same species. Here, we tested the evolution of increased competitive ability (EICA) hypothesis in two common garden experiments in which Chromolaena odorata plants originating from native and nonnative ranges were grown in competition with natives from each range, and the novel weapons hypothesis in laboratory experiments with leachates from C. odorata. Compared with conspecifics originating from the native range, C. odorata plants from the nonnative range were stronger competitors at high nutrient concentrations in the nonnative range in China and experienced far more herbivore damage in the native range in Mexico. In both China and Mexico, C. odorata was more suppressed by species native to Mexico than by species native to China. Species native to China were much more inhibited by leaf extracts from C. odorata than species from Mexico, and this difference in allelopathic effects may provide a possible explanation for the biogeographic differences in competitive ability. Our results indicate that EICA, innate competitive advantages, and novel biochemical weapons may act in concert to promote invasion by C. odorata, and emphasize the importance of exploring multiple, non-mutually exclusive mechanisms for invasions. © 2012 The Authors.

Full Text Available A company’s core competitiveness depends on the strategic allocation of its human resources in alignment with employee capabilities. Competency models can identify the range of capabilities at a company’s disposal, and this information can be used to develop internal or external education training policies for sustainable development. Such models can ensure the importation of a strategic orientation reflecting the growth of its employee competence set and enhancing human resource sustainably. This approach ensures that the most appropriate people are assigned to the most appropriate positions. In this study, we proposed a new hybrid multiple attributed decision-making model by using the Decision-making trial and Evaluation Laboratory Technique (DEMATEL to construct an influential network relation map (INRM and determined the influential weights by using the basic concept of the analytic network process (called DEMATEL-based ANP, DANP; the influential weights were then adopted with a modified Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR method. A simple forecasting technique as an iteration function was also proposed. The proposed model was effective. We expect that the proposed model can facilitate making timely revisions, reflecting the growth of employee competence sets, reducing the performance gap toward the aspiration level, and ensuring the sustainability of a company.
Long-term energy supply contracts in European competition policy: Fuzzy not crazy
International Nuclear Information System (INIS)
Hauteclocque, Adrien de; Glachant, Jean-Michel
2009-01-01
Long-term supply contracts often have ambiguous effects on the competitive structure, investment and consumer welfare in the long term. In the new market context, these effects are likely to be worsened and thus even harder to assess. Since liberalization and especially since the release of the Energy Sector Inquiry in early 2007, the portfolio of long-term supply contracts of the former incumbents have become a priority for review by the European Commission and the national competition authorities. It is widely believed that European Competition authorities take a dogmatic view on these contracts and systemically emphasize the risk of foreclosure over their positive effects on investment and operation. This paper depicts the methodology that has emerged in the recent line of cases and argues that this interpretation is largely misguided. It shows that a multiple-step approach is used to reduce regulation costs and balance anti-competitive effects with potential efficiency gains. However, if an economic approach is now clearly implemented, competition policy is constrained by the procedural aspect of the legal process and the remedies imposed remain open for discussion.

Immunoglobulin-binding protein (BiP) is a molecular chaperone of the heat shock protein 70 (Hsp70) family. BiP is localized in the endoplasmic reticulum (ER) and plays key roles in protein translocation, protein folding and quality control in the ER. The genomes of flowering plants contain multiple BiP genes. Arabidopsis thaliana has three BiP genes. BIP1 and BIP2 are ubiquitously expressed. BIP3 encodes a less well conserved BiP paralog, and it is expressed only under ER stress conditions in the majority of organs. Here, we report that all BiP genes are expressed and functional in pollen and pollen tubes. Although the bip1 bip2 double mutation does not affect pollen viability, the bip1 bip2 bip3 triple mutation is lethal in pollen. This result indicates that lethality of the bip1 bip2 double mutation is rescued by BiP3 expression. A decrease in the copy number of the ubiquitously expressed BiP genes correlates well with a decrease in pollen tube growth, which leads to reduced fitness of mutant pollen during fertilization. Because an increased protein secretion activity is expected to increase the protein folding demand in the ER, the multiple BiP genes probably cooperate with each other to ensure ER homeostasis in cells with active secretion such as rapidly growing pollen tubes.

Competition among pollen grains from a single donor is expected to increase the quality of the offspring produced because of the recessive deleterious alleles expressed during pollen-tube growth. However, evidence for such an effect is inconclusive; a large number of studies suffer from confounding variation in pollen competition with variation in pollen load. In this study, we tested the effect of pollen competition on offspring performance independently of pollen-load variation. We compared seed mass and early seedling performance in Dalechampia scandens (Euphorbiaceae) between crosses in which variation in pollen competition was achieved, without variation in pollen load, by manipulating the dispersion of pollen grains on the stigmas. Despite a large sample size (211 crosses on 20 maternal plants), we failed to find an effect of pollen competition on seed characteristics or early seedling performance. Paternal effects were always limited, and pollen competition never reduced the within-father (residual) variance. These results suggest that limited within-donor variation in genetic quality of pollen grains reduces the potential benefits of pollen competition in the study population. The lack of paternal effects on early sporophyte performance further suggests that benefits of pollen competition among pollen from multiple donors should be limited as well, and it raises questions about the significance of pollen competition as a mechanism of sexual selection. © 2016 Botanical Society of America.

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 purpose of the present study was to characterize the genetic damage induced by paradoxical sleep deprivation (PSD) in combination with cocaine or ecstasy (3,4-methylenedioxymethamphetamine; MDMA) in multiple organs of male mice using the single cell gel (comet) assay. C57BL/6J mice were submitted to PSD by the platform technique for 72 hours, followed by drug administration and evaluation of DNA damage in peripheral blood, liver and brain tissues. Cocaine was able to induce genetic damage in the blood, brain and liver cells of sleep-deprived mice at the majority of the doses evaluated. Ecstasy also induced increased DNA migration in peripheral blood cells for all concentrations tested. Analysis of damaged cells by the tail moment data suggests that ecstasy is a genotoxic chemical at the highest concentrations tested, inducing damage in liver or brain cells after sleep deprivation in mice. Taken together, our results suggest that cocaine and ecstasy/MDMA act as potent genotoxins in multiple organs of mice when associated with sleep loss.

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.

Full Text Available The case for Competitive Intelligence (CI as an instrument that can enhance the competitiveness of South African companies and South Africa as a country is strong. 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.

Making progress basically, a fundamental issue for the construction companies to get by in a highly competitive industry. From time to time, industry players are facing stiff and tough competition due to large number of players, whether existing or new players involved from various background and track record. Furthermore, the large numbers of component deciding the competitiveness of contractors, whose organization structures and governance have turned out to be more muddled. Different construction companies have their own unique criteria which may differ from one to another. The enormous amount of issues needs to bring down to manageable numbers so that measures can be identified and scrutinized to enhance competitiveness. This paper discusses the result from the critical investigation from past studies in the Asian countries, namely China, India, Thailand, Singapore and Malaysia. Several fundamental factors have been identified as CSFs in construction companies in respective country. Also highlighted a critical survey based upon various literatures written on this subject where critical success factors (CSFs) as a yardstick to gauge the relationship among CSFs in various construction companies in the Asian region. Far reaching estimation of an organization's performance and resulting input to its supervision is crucial for business change. Estimation additionally empowers organizations to be contrasted from one another on the premise of institutionalized data, permitting best practices to be distinguished and connected more widely. Different countries have their own set of critical success factors (CSFs) which may differ in term of priority and at the same time share common elements of success factor in accomplishment as a construction companies. The study, which is exploratory in nature, embraced the content investigation and inductive technique to accomplish its objectives.

Full Text Available The aim of the study was to determine, how young sports climbers evaluate reasons for participating in climbing competitions. For this purpose we interviewed 125 competitors of both genders, year of birth 2002 and younger. Children were participating in the competitions for East and West League in the youngest category. Data were collected with a close-ended questionnaire. The acquired data were processed with SPSS software programme; frequencies were carried out. Mean age was 8.9 years. Most young athletes, 42.4%, attend competitions with the purpose of gaining new experience, followed by those whose main goal is good climbing. These are 40.8%. 14.4% attend competitions to achieve good result and 2.4% for reason of socializing. 19.2% of children don't care if they don't reach the top of the climbing route, but 80.8% are slightly to quite dissatisfied. The study shows that internal motivation is dominant in young climbers. Mostly they attend competitions to gain new experience and to show good climbing. If they don't reach the top of the climbing route, they leave competition unsatisfied. It would be reasonable to consider the study results in the organization of competitions for youngest categories.

Using resource-based view of the firm as a theoretical perspective, this paper aims to analyze how strategic resources can contribute to the competitive priorities of an organization that operates in the logistic sector. The research method used was the case study using as the main technique of data collection semi-structured and structured interviews; and, systematic observations. The resources that contribute effectively to competitive priorities that need improvement are sales control, loyal customer base, partners experience and agile feedback to customers. However, only the experience of the partners provides to the company sustainable competitive advantage. Others resources identified in the field research provide only a competitive parity, despite this, support important competitive priorities.

The biggest contributing sector to this expansion is the industry. This sector contributed the most with 2,3% to this growth. The importance of the industry in a country’s development not only the Romania`s case, but for other economies too. More and more authors emphasise the importance of Industrial parks, they act as pull factors. The effects of the industrial placements like the industrial parks are multiple regarding a region’s development and competitiveness. The most of these benefits are well known already, but the competitiveness of the industrial parks is not a frequent theme, tough this will contribute to the competitiveness of the region. What are the basic and decisive factors that influence the final decision of the companies to choose a particular industrial park? While analysing the competitiveness factors of industrial parks I intend to emphasize the reasons and factors that influences companies in their decision to appear in the industrial parks that they are resident in. The purpose of this paper is to present all the important factors in the same place that make an industrial park competitive. First I want to present the factors that were identified by now based on theoretical, and practical experiences starting from some second hand information. The caracteristics of the successful parks will br presented with the well-kown examples, and also with caese not known to everybody. Some of the reasons why industrial companies chooses a park are well kown, for example the placement, the good accesibility, for which is essential a good infrastructure. Another decisive factor is the suport of the state and the local autorities, the most important factors are tax and other costs relief. There are more things that influance companies in choosing their sites.
An agent-based model for emotion contagion and competition in online social media
Fan, Rui; Xu, Ke; Zhao, Jichang
2018-04-01
Recent studies suggest that human emotions diffuse in not only real-world communities but also online social media. However, a comprehensive model that considers up-to-date findings and multiple online social media mechanisms is still missing. To bridge this vital gap, an agent-based model, which concurrently considers emotion influence and tie strength preferences, is presented to simulate the emotion contagion and competition. Our model well reproduces patterns observed in the empirical data, like anger's preference on weak ties, anger-dominated users' high vitalities and angry tweets' short retweet intervals, and anger's competitiveness in negative events. The comparison with a previously presented baseline model further demonstrates its effectiveness in modeling online emotion contagion. It is also surprisingly revealed by our model that as the ratio of anger approaches joy with a gap less than 12%, anger will eventually dominate the online social media and arrives the collective outrage in the cyber space. The critical gap disclosed here can be indeed warning signals at early stages for outrage control. Our model would shed lights on the study of multiple issues regarding emotion contagion and competition in terms of computer simulations.
Natal Host Plants Can Alter Herbivore Competition.

2016-01-01
Interspecific competition between herbivores is widely recognized as an important determinant of community structure. Although researchers have identified a number of factors capable of altering competitive interactions, few studies have addressed the influence of neighboring plant species. If adaptation to/ epigenetic effects of an herbivore's natal host plant alter its performance on other host plants, then interspecific herbivore interactions may play out differently in heterogeneous and homogenous plant communities. We tested wether the natal host plant of a whitefly population affected interactions between the Middle-east Asia Minor 1 (MEAM1) and Mediterranean (MED) cryptic species of the whitefly Bemisia tabaci by rearing the offspring of a cabbage-derived MEAM1 population and a poinsettia-derived MED population together on three different host plants: cotton, poinsettia, and cabbage. We found that MED dominated on poinsettia and that MEAM1 dominated on cabbage, results consistent with previous research. MED also dominated when reared with MEAM1 on cotton, however, a result at odds with multiple otherwise-similar studies that reared both species on the same natal plant. Our work provides evidence that natal plants affect competitive interactions on another plant species, and highlights the potential importance of neighboring plant species on herbivore community composition in agricultral systems.

Full Text Available Competition for nitrogen (N, particularly in resource-limited habitats, might be avoided by different N acquisition strategies of plants. In our study, we investigated whether slow-growing European beech and fast-growing sycamore maple seedlings avoid competition for growth-limiting N by different N uptake patterns and the potential alteration by soil N availability in a microcosm experiment. We quantified growth and biomass indices, 15N uptake capacity and N pools in the fine roots. Overall, growth indices, N acquisition and N pools in the fine roots were influenced by species-specific competition depending on soil N availability. With interspecific competition, growth of sycamore maple reduced regardless of soil N supply, whereas beech only showed reduced growth when N was limited. Both species responded to interspecific competition by alteration of N pools in the fine roots; however, sycamore maple showed a stronger response compared to beech for almost all N pools in roots, except for structural N at low soil N availability. Beech generally preferred organic N acquisition while sycamore maple took up more inorganic N. Furthermore, with interspecific competition, beech had an enhanced organic N uptake capacity, while in sycamore maple inorganic N uptake capacity was impaired by the presence of beech. Although sycamore maple could tolerate the suboptimal conditions at the cost of reduced growth, our study indicates its reduced competitive ability for N compared to beech.

Full Text Available Knowledge management is one of the most popular themes of modern scientific literature. However, in spite of all the published research on the importance of knowledge management, there is little said about knowledge as a direct source of a firm’s competitive advantage. In the past decades, three main hypotheses on the sources of a firm’s competitive advantage were developed; namely, the industrial organization, the resource-based and the capability-based hypotheses. In this paper, we argue that the knowledge-based hypothesis can and should be considered as the fourth tantamount hypothesis on how the sources of the competitive advantage of a firm can be explained.
Competition and quality in a physiotherapy market with fixed prices.
Pekola, Piia; Linnosmaa, Ismo; Mikkola, Hennamari
2017-01-01
Our study focuses on competition and quality in physiotherapy organized and regulated by the Social Insurance Institution of Finland (Kela). We first derive a hypothesis with a theoretical model and then perform empirical analyses of the data. Within the physiotherapy market, prices are regulated by Kela, and after registration eligible firms are accepted to join a pool of firms from which patients choose service providers based on their individual preferences. By using 2SLS estimation techniques, we analyzed the relationship among quality, competition and regulated price. According to the results, competition has a statistically significant (yet weak) negative effect (p = 0.019) on quality. The outcome for quality is likely caused by imperfect information. It seems that Kela has provided too little information for patients about the quality of the service.

Patients who have undergone pelvic irradiation are reported to be at an increased risk of subsequently developing malignancies of the pelvic organs. We report a case of multiple cancers in the pelvic organs after radiation therapy for uterine cancer. The patient was a 76-year-old woman who had undergone a hysterectomy with radiation therapy for uterine cancer in 1960. Thereafter, she had undergone a total cystectomy for bladder cancer in 1989; an abdominoperineal resection for rectal cancer with radiation proctitis in February 1991; and a right hemicolectomy for cecum cancer in 1995. Then, in 2005, she was found to have early cancer of the sigmoid colon at the stoma, so that the colon was dissected from the periphery of the stoma, the sigmoid colon was removed, and an artificial anus was reconstructed again. The histopathological diagnosis was early well-differentiated adenocarcinoma. She had undergone three operations for multiple cancers of the large intestine in the pelvis at different times during 16 years since 1989 when the bladder cancer was detected and surgically treated. And she has been alive and well. Long-term follow-up would be mandatory for such patients undergone pelvic irradiation who might be able to survive for a long time with appropriate therapies like this patient. (author)

Full Text Available Purpose. In this paper it is necessary to analyze the types of competition in the transport market in order to find ways to improve the competitiveness of railway transport and to determine the ensuring equal conditions for all market participants by eliminating discrimination in competition. Methodology. Analysis of recent research and publications on the subject was held by the authors. The question of the development of competition, increased competitiveness in railway transport was investigated. Attention is drawn to the fact that due to the decline in traffic volumes on all modes of transport competition may significantly change the usual sphere the effective use of different modes of transport. Every mode of transport occupies a particular segment of the transport market, taking into account its technical and economic features, weakly competing, and in some cases do not compete with each other (except the road transport. However, it is entirely possible competition inside these segments.Findings. The problems of management of competitiveness, including the transport market, which required extensive analysis and serious scientific study, were identified. Originality. As a result of this work the features of transport and production of transport in modern conditions were structured. The dependences of passenger turnover and freight turnover by mode of transport over the past decade were shown. The question of additional profits by providing the cargo owners a range of service was examined. The optimal combination of cost and quality of such services at each transportation company promotes increasing its competitive status. Practical value. Competition between enterprises of the industry put the aim of improving the competitiveness of not only railway subsystems directly involved in technology movement of cargoes and the movement of passengers, but also the organization of infrastructure in the first place – subsystems to expand services
Multiple mechanisms enable invasive species to suppress native species.
Bennett, Alison E; Thomsen, Meredith; Strauss, Sharon Y
2011-07-01
Invasive plants represent a significant threat to ecosystem biodiversity. To decrease the impacts of invasive species, a major scientific undertaking of the last few decades has been aimed at understanding the mechanisms that drive invasive plant success. Most studies and theories have focused on a single mechanism for predicting the success of invasive plants and therefore cannot provide insight as to the relative importance of multiple interactions in predicting invasive species' success. We examine four mechanisms that potentially contribute to the success of invasive velvetgrass Holcus lanatus: direct competition, indirect competition mediated by mammalian herbivores, interference competition via allelopathy, and indirect competition mediated by changes in the soil community. Using a combination of field and greenhouse approaches, we focus on the effects of H. lanatus on a common species in California coastal prairies, Erigeron glaucus, where the invasion is most intense. We found that H. lanatus had the strongest effects on E. glaucus via direct competition, but it also influenced the soil community in ways that feed back to negatively influence E. glaucus and other native species after H. lanatus removal. This approach provided evidence for multiple mechanisms contributing to negative effects of invasive species, and it identified when particular strategies were most likely to be important. These mechanisms can be applied to eradication of H. lanatus and conservation of California coastal prairie systems, and they illustrate the utility of an integrated set of experiments for determining the potential mechanisms of invasive species' success.
Wake up and smell the conflict: odour signals in female competition
Stockley, Paula; Bottell, Lisa; Hurst, Jane L.
2013-01-01
Odour signals used in competitive and aggressive interactions between males are well studied in the context of sexual selection. By contrast, relatively little is known about comparable signals used by females, despite current interest in the evolution of female ornaments and weaponry. Available evidence suggests that odour signals are important in competitive interactions between female mammals, with reductions or reversals of male-biased sexual dimorphism in signalling where female competition is intense. Scent marking is often associated with conflict between females over access to resources or reproductive opportunities. Female scent marks may therefore provide reliable signals of competitive ability that could be used both by competitors and potential mates. Consistent with this hypothesis, we report that aggressive behaviour of female house mice is correlated with the amount of major urinary protein (MUP) excreted in their urine, a polymorphic set of proteins that are used in scent mark signalling. Under semi-natural conditions, females with high MUP output are more likely to produce offspring sired by males that have high reproductive success, and less likely to produce offspring by multiple different sires, suggesting that females with strong MUP signals are monopolized by males of particularly high quality. We conclude that odour signals are worthy of more detailed investigation as mediators of female competition. PMID:24167312
Sperm competition in humans: mate guarding behavior negatively correlates with ejaculate quality.
Leivers, Samantha; Rhodes, Gillian; Simmons, Leigh W
2014-01-01
In species where females mate with multiple males, the sperm from these males must compete to fertilise available ova. Sexual selection from sperm competition is expected to favor opposing adaptations in males that function either in the avoidance of sperm competition (by guarding females from rival males) or in the engagement in sperm competition (by increased expenditure on the ejaculate). The extent to which males may adjust the relative use of these opposing tactics has been relatively neglected. Where males can successfully avoid sperm competition from rivals, one might expect a decrease in their expenditure on tactics for the engagement in sperm competition and vice versa. In this study, we examine the relationship between mate guarding and ejaculate quality using humans as an empirical model. We found that men who performed fewer mate guarding behaviors produced higher quality ejaculates, having a greater concentration of sperm, a higher percentage of motile sperm and sperm that swam faster and less erratically. These effects were found independent of lifestyle factors or factors related to male quality. Our findings suggest that male expenditure on mate guarding and on the ejaculate may represent alternative routes to paternity assurance in humans.

Full Text Available Doing business in modern days is characterized by a large number of suppliers of products and / or services that can meet our needs in the same or similar manner. For this reason, each organization has to constantly monitor the competitiveness of the market, to innovate in order to maintain the existing place on the market or possibly reach new markets. The purpose of conducted research was to assess the factors which are important for achieving a competitive advantage, increasing innovative activities and to identify factors which are crucial for the entry and penetration into new markets, as well as to determine the correlation of these factors with different characteristics of organization (size, level and duration of business. The results have shown that marketing is recognized as the most important factor for achieving a competitive advantage. Innovative activities are usually of imitative character, while consumers and their needs and requirements are largely ignored.

Hu, Yu; Zhu, Yi
2018-01-01
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.
Competitive positioning of power generation plants in a deregulated market

Stephens, J.
1998-01-01
As industrialized countries deregulate their electric power industries, there is a fundamental shift from guaranteed cost recovery to open market competition on a deregulated grid. Utilities generally competitively bid into a power exchange where the lowest cost power providers are dispatched first. Therefore, the competitiveness of utilities determines their profitability. This commercial structure compels power generators to seek out ways of improving their equipment and plant performance. The inevitability of this trend is demonstrated by a look at the installed base in the US where the move toward deregulation is gaining momentum. More than half of the generating plants in the US are over 20 years old. The average thermal efficiency nation-wide is 33%. In contrast, contemporary coal-and gas-fired plants can operate at efficiency levels up to 45 percent and 55 to 60%, respectfully. With new facilities coming on-line, existing plants will need to make improvements to be dispatched. When deregulation fully envelopes the US market, utilities will not all fit into one pattern; their strategies and actions will depend on a multiple set of factors. Their success will be based on their ability to change landscapes from guaranteed cost recovery to competitive bidding. This paper discussers technical and commercial options available to power producers to improve their competitive positions in a deregulated market as well as software for determining the competitiveness of specific power plants and the location-based market prices of electricity. Examples of the application of alternatives will be cited along with expected payback and impact on cents per kilowatt-hour production costs

Full Text Available The objective of this research is to determine the competitiveness level of the manufacturing small and medium-sized enterprises (SMEs of Baja California and to identify which areas within them affect this competitiveness. The methodology used is descriptive, correlational, and cross-sectional; the systemic competitiveness model is developed at the micro level, and a measurement instrument with 64 questions is used on 195 companies in the state; in addition, traditional multiple linear regressions are performed to test the hypotheses. One of the findings is that the SMEs in the state have a medium-low competitiveness level and do not show any relationship between the size of the companies and their competitiveness; however, the production-operations area prove to be more important for their competitiveness level. Although the measurement instrument that is used has no proportionality at the municipality and subsector level, it does allow us to approach the internal operation of the SMEs.

Interhospital competition has been shown to influence the adoption of surgical techniques and approaches, clinical patient outcomes, and health care resource use for select surgical procedures. However, little is known regarding these dynamics as they relate to spine surgery. This investigation sought to examine the relationship between interhospital competitive intensity and perioperative outcomes following lumbar spinal fusion. This study used the Nationwide Inpatient Sample dataset, years 2003, 2006, and 2009. Patients were included based on the presence of the International Classification of Disease, Ninth Edition, Clinical Modification (ICD-9-CM) codes corresponding to lumbar spinal fusion, as well as on the presence of data on the Herfindahl-Hirschman Index (HHI). The outcome measures are perioperative complications, defined using an ICD-9-CM coding algorithm. The HHI, a validated measure of competition within a market, was used to assess hospital market competitiveness. The HHI was calculated based on the hospital cachement area. Multiple regression was performed to adjust for confounding variables including patient age, gender, primary payer, severity of illness score, primary versus revision fusion, anterior versus posterior approach, national region, hospital bed size, location or teaching status, ownership, and year. Perioperative clinical outcomes were assessed based on ICD-9-CM codes with modifications. In total, 417,520 weighted patients (87,999 unweighted records) were analyzed. The mean cachement area HHI was 0.31 (range 0.099-0.724). The average patient age was 55.4 years (standard error=0.194), and the majority of patients were female (55.8%, n=232,727). The majority of procedures were primary spinal fusions (92.7%, n=386,998) and fusions with a posterior-only technique (81.5%, n=340,271). Most procedures occurred in the South (42.5%, n=177,509) or the Midwest (27.0%, n=112,758) regions. In the multiple regression analysis, increased hospital

Full Text Available When the vehicle-treated, sham-operated mice underwent heat stress, the fraction survival and core temperature at +4 h of body heating were found to be 5 of 15 and 34.4∘C±0.3∘C, respectively. Castration 2 weeks before the start of heat stress decreased the plasma levels of testosterone almost to zero, protected the mice from heat-induced death (fraction survival, 13/15 and reduced the hypothermia (core temperature, 37.3∘C. The beneficial effects of castration in ameliorating lethality and hypothermia can be significantly reduced by testosterone replacement. Heat-induced apoptosis, as indicated by terminal deoxynucleotidyl- transferase- mediatedαUDP-biotin nick end-labeling staining, were significantly prevented by castration. In addition, heat-induced neuronal damage, as indicated by cell shrinkage and pyknosis of nucleus, to the hypothalamus was also castration-prevented. Again, the beneficial effects of castration in reducing neuronal damage to the hypothalamus as well as apoptosis in multiple organs during heatstroke, were significantly reversed by testosterone replacement. The data indicate that testosterone depletion by castration may protect mice from heatstroke-induced multiple organ damage and lethality.

Full Text Available The fundamental and applied research, the technologic transfer and more particularly, the innovation work – as a component part of the said research activity – stand for aspects to which economies have, lately, started to grant increased importance. The rapid changes in the characteristics of external markets, as well as those in the technologic field are challenges for more frequent and more rapid innovations, with the end result in new products, processes and technologies. Innovation is the leading force of competitiveness, of growth, of profitability, as well as of the creation of durable values since it is well known that the competitive advantage, so much wished-for by any organization which operates in a highly competitive environment, is volatile, hard to obtain.

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.

Tackling Energy Loss for High-Efficiency Organic Solar Cells with Integrated Multiple Strategies.
Zuo, Lijian; Shi, Xueliang; Jo, Sae Byeok; Liu, Yun; Lin, Fracis; Jen, Alex K-Y
2018-04-01
Limited by the various inherent energy losses from multiple channels, organic solar cells show inferior device performance compared to traditional inorganic photovoltaic techniques, such as silicon and CuInGaSe. To alleviate these fundamental limitations, an integrated multiple strategy is implemented including molecular design, interfacial engineering, optical manipulation, and tandem device construction into one cell. Considering the close correlation among these loss channels, a sophisticated quantification of energy-loss reduction is tracked along with each strategy in a perspective to reach rational overall optimum. A novel nonfullerene acceptor, 6TBA, is synthesized to resolve the thermalization and V OC loss, and another small bandgap nonfullerene acceptor, 4TIC, is used in the back sub-cell to alleviate transmission loss. Tandem architecture design significantly reduces the light absorption loss, and compensates carrier dynamics and thermalization loss. Interfacial engineering further reduces energy loss from carrier dynamics in the tandem architecture. As a result of this concerted effort, a very high power conversion efficiency (13.20%) is obtained. A detailed quantitative analysis on the energy losses confirms that the improved device performance stems from these multiple strategies. The results provide a rational way to explore the ultimate device performance through molecular design and device engineering. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Project safety as a sustainable competitive advantage.
Rechenthin, David
2004-01-01
To be consistently profitable, a construction company must complete projects in scope, on schedule, and on budget. At the same time, the nature of the often high-risk work performed by construction companies can result in high accident rates. Clients and other stakeholders are placing increasing pressure on companies to decrease those accident rates. Clients routinely demand copies of safety plans and evidence of past results at the "pre-qualification" or "request for proposal" stages of the procurement process. Are high accident rates and the associated costs just a part of business? Companies that deliver on scope, schedule, and budget have a competitive advantage. Is it possible for projects with low accident rates to use it as a competitive advantage? Is the value added by safety just a temporary or parity issue, or does a successful safety program offer significant advantage to the company and the client? This article concludes that in the case of a high-risk industry, such as the construction industry, an organization with a successful safety program can promote safety performance as a sustainable competitive advantage. It is a choice the company can make.

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.

Given the costs of multiple mating, why has female polyandry evolved? Utetheisa ornatrix moths are well suited for studying multiple mating in females because females are highly polyandrous over their life span, with each male mate transferring a substantial spermatophore with both genetic and nongenetic material. The accumulation of resources might explain the prevalence of polyandry in this species, but another, not mutually exclusive, possibility is that females mate multiply to increase the probability that their sons will inherit more-competitive sperm. This latter "sexy-sperm" hypothesis posits that female multiple mating and male sperm competitiveness coevolve via a Fisherian runaway process. We tested the sexy-sperm hypothesis by using competitive double matings to compare the sperm competition success of sons of polyandrous versus monandrous females. In accordance with sexy-sperm theory, we found that in 511 offspring across 17 families, the male whose polyandrous mother mated once with each of three different males sired significantly more of all total offspring (81%) than did the male whose monandrous mother was mated thrice to a single male. Interestingly, sons of polyandrous mothers had a significantly biased sex ratio of their brood toward sons, also in support of the hypothesis. © 2015 The Author(s).

Clustering Multiple Sclerosis Subgroups with Multifractal Methods and Self-Organizing Map Algorithm
Karaca, Yeliz; Cattani, Carlo
Magnetic resonance imaging (MRI) is the most sensitive method to detect chronic nervous system diseases such as multiple sclerosis (MS). In this paper, Brownian motion Hölder regularity functions (polynomial, periodic (sine), exponential) for 2D image, such as multifractal methods were applied to MR brain images, aiming to easily identify distressed regions, in MS patients. With these regions, we have proposed an MS classification based on the multifractal method by using the Self-Organizing Map (SOM) algorithm. Thus, we obtained a cluster analysis by identifying pixels from distressed regions in MR images through multifractal methods and by diagnosing subgroups of MS patients through artificial neural networks.
Biased Competition in Visual Processing Hierarchies: A Learning Approach Using Multiple Cues.

In this contribution, we present a large-scale hierarchical system for object detection fusing bottom-up (signal-driven) processing results with top-down (model or task-driven) attentional modulation. Specifically, we focus on the question of how the autonomous learning of invariant models can be embedded into a performing system and how such models can be used to define object-specific attentional modulation signals. Our system implements bi-directional data flow in a processing hierarchy. The bottom-up data flow proceeds from a preprocessing level to the hypothesis level where object hypotheses created by exhaustive object detection algorithms are represented in a roughly retinotopic way. A competitive selection mechanism is used to determine the most confident hypotheses, which are used on the system level to train multimodal models that link object identity to invariant hypothesis properties. The top-down data flow originates at the system level, where the trained multimodal models are used to obtain space- and feature-based attentional modulation signals, providing biases for the competitive selection process at the hypothesis level. This results in object-specific hypothesis facilitation/suppression in certain image regions which we show to be applicable to different object detection mechanisms. In order to demonstrate the benefits of this approach, we apply the system to the detection of cars in a variety of challenging traffic videos. Evaluating our approach on a publicly available dataset containing approximately 3,500 annotated video images from more than 1 h of driving, we can show strong increases in performance and generalization when compared to object detection in isolation. Furthermore, we compare our results to a late hypothesis rejection approach, showing that early coupling of top-down and bottom-up information is a favorable approach especially when processing resources are constrained.

Competition between roots and microorganisms for nitrogen: mechanisms and ecological relevance
Kuzyakov, Yakov; Xu, Xingliang
2014-05-01
Demand of all living organisms on the same nutrients forms the basis for interspecific competition between plants and microorganisms in soils. This competition is especially strong in the rhizosphere. To evaluate competitive and mutualistic interactions between plants and microorganisms and to analyse ecological consequences of these interactions, we analysed 424 data pairs from 41 15N-labelling studies that investigated 15N redistribution between roots and microorganisms. Calculated Michaelis-Menten kinetics based on Km (Michaelis constant) and Vmax (maximum uptake capacity) values from 77 studies on the uptake of nitrate, ammonia, and amino acids by roots and microorganisms clearly showed that, shortly after nitrogen (N) mobilization from soil organic matter and litter, microorganisms take up most N. Lower Km values of microorganisms suggest that they are especially efficient at low N concentrations, but can also acquire more N at higher N concentrations (Vmax) compared with roots. Because of the unidirectional flow of nutrients from soil to roots, plants are the winners for N acquisition in the long run. Therefore, despite strong competition between roots and microorganisms for N, a temporal niche differentiation reflecting their generation times leads to mutualistic relationships in the rhizosphere. This temporal niche differentiation is highly relevant ecologically because it: protects ecosystems from N losses by leaching during periods of slow or no root uptake; continuously provides roots with available N according to plant demand; and contributes to the evolutionary development of mutualistic interactions between roots and microorganisms.

Full Text Available Understanding everyday behavior relies heavily upon understanding our ability to improvise, how we are able to continuously anticipate and adapt in order to coordinate with our environment and others. Here we consider the ability of musicians to improvise, where they must spontaneously coordinate their actions with co-performers in order to produce novel musical expressions. Investigations of this behavior have traditionally focused on describing the organization of cognitive structures. The focus, here, however, is on the ability of the time-evolving patterns of inter-musician movement coordination as revealed by the mathematical tools of complex dynamical systems to provide a new understanding of what potentiates the novelty of spontaneous musical action. We demonstrate this approach through the application of cross wavelet spectral analysis, which isolates the strength and patterning of the behavioral coordination that occurs between improvising musicians across a range of nested time-scales. Revealing the sophistication of the previously unexplored dynamics of movement coordination between improvising musicians is an important step towards understanding how creative musical expressions emerge from the spontaneous coordination of multiple musical bodies.

Succession planning has been defined as the process by which one or more successors are identified for key positions, development activities are planned for identified successors, or both. Limited research exists pertaining to the relationship between hospital succession planning and financial performance, particularly in the context of market competition. We used the resource-based view framework to analyze the differential effect of succession planning on hospitals' financial performance based on market competition. According to RBV, organizations can achieve higher performance by using their superior resources and capabilities. We used a panel design consisting of a national sample of hospitals in the United States for 2006-2010. We analyzed data using multivariate linear regression with facility random effects and year and state fixed effects. The sample included 22,717 hospital-year observations; more than one half of the hospitals (55.4%) had a succession planning program. The study found a positive relationship between the presence of succession planning and financial performance (β = 1.41, p planning programs on the basis of competition in their market.

Pemetrexed, a multitargeted antifolate, is eliminated by tubular secretion via human organic anion transporter 3 (hOAT3). Although proton pump inhibitors (PPIs) are frequently used in cancer patients, the drug interaction between PPIs and pemetrexed remains to be clarified. In this study, we examined the drug interaction between pemetrexed and PPIs in hOAT3-expressing cultured cells, and retrospectively analyzed the impact of PPIs on the development of hematologic toxicity in 108 patients who received pemetrexed and carboplatin treatment of nonsquamous non-small cell lung cancer for the first time between January 2011 and June 2015. We established that pemetrexed was transported via hOAT3 (Km = 68.3 ± 11.1 µM). Lansoprazole, rabeprazole, pantoprazole, esomeprazole, omeprazole, and vonoprazan inhibited hOAT3-mediated uptake of pemetrexed in a concentration-dependent manner. The inhibitory effect of lansoprazole was much greater than those of other PPIs and the apparent IC50 value of lansoprazole against pemetrexed transport via hOAT3 was 0.57 ± 0.17 µM. The inhibitory type of lansoprazole was competitive. In a retrospective study, multivariate analysis revealed that coadministration of lansoprazole, but not other PPIs, with pemetrexed and carboplatin was an independent risk factor significantly contributing to the development of hematologic toxicity (odds ratio: 10.004, P = 0.005). These findings demonstrated that coadministration of lansoprazole could exacerbate the hematologic toxicity associated with pemetrexed, at least in part, by competitive inhibition of hOAT3. Our results would aid clinicians to make decisions of coadministration drugs to avoid drug interaction-induced side effects for achievement of safe and appropriate chemotherapy with pemetrexed.

Infrastructure is an important component in building competitiveness of a region. Present global scenario of economic slowdown that is led by slump in demand of goods and services and decreasing capacity of government institutions in investing public infrastructure. Strategy of augmenting competitiveness of a region can be built around improving efficient distribution of public infrastructure in the region. This efficiency in the distribution of infrastructure will reduce the burden of government institution and improve the relative output of the region in relative lesser investment. A rigorous literature study followed by an expert opinion survey (RIDIT scores) reveals that Railway, Road, ICTs and Electricity infrastructure is very crucial for better competitiveness of a region. Discussion with Experts in ICTs, Railways and Electricity sectors were conducted to find the issues, hurdles and possible solution for the development of these sectors. In an underdeveloped country like India, there is a large constrain of financial resources, for investment in infrastructure sector. Judicious planning for allocation of resources for infrastructure provisions becomes very important for efficient and sustainable development. Data Envelopment Analysis (DEA) is the mathematical programming optimization tool that measure technical efficiency of the multiple-input and/or multiple-output case by constructing a relative technical efficiency score. This paper tries to utilize DEA to identify the efficiency at which present level of selected components of Infrastructure (Railway, Road, ICTs and Electricity) is utilized in order to build competitiveness of the region. This paper tries to identify a spatial pattern of efficiency of Infrastructure with the help of spatial auto-correlation and Hot-spot analysis in Arc GIS. This analysis leads to policy implications for efficient allocation of financial resources for the provision of infrastructure in the region and building a
Head to head: The role of academic competition in undergraduate anatomical education.
Van Nuland, Sonya E; Roach, Victoria A; Wilson, Timothy D; Belliveau, Daniel J
2015-01-01
Competition is a key element in many educational games and is often adopted by educators in an effort to motivate and excite their students. Yet, the use of academic competition in educational institutions remains the subject of much debate. Opponents argue that academic competition causes an increase in student anxiety and divides their attention. However, if the contexts of academic competition are defined, could the inclusion of a game-like competition in a university course be a viable and beneficial method of engaging students? Students (n = 67) were recruited from an undergraduate human anatomy course at Western University. Using a crossover design, students were exposed to a competitive tournament either at the time of their first term test or second term test. The anatomical knowledge of participating students was assessed prior to the start of the study using a baseline anatomy test. Following treatment with an online competitive anatomy tournament, student's term test grades and final course grades were analyzed. Both the second term test scores (F(2,64) = 3.743, P = 0.029) and overall course grades (F(2,64) = 3.356, P = 0.041) were found to be significantly different (P < 0.05) for individuals in the competitive group when compared to their non-competing peers. As suggested by the literature where organized competition in the classroom correlates to improved academic performance, this study uncovered significant results pertaining to increased academic performance resulting from participating in tournament-based competition. In light of these positive results, further exploration of the effects of academic competition on student performance across age brackets and disciplines is warranted. © 2014 American Association of Anatomists.
Anti- versus Pro-Competitive Mergers

In a framework where mergers are mutually excluding, I show that firms pursue anti- rather than (alternative) pro-competitive mergers. Potential outsiders to anti-competitive mergers refrain from pursuing pro-competitive mergers if the positive externalities from anti-competitive mergers are strong enough. Potential outsiders to pro-competitive mergers pursue anti-competitive mergers if the negative externalities from the pro-competitive mergers are strong enough. Potential participants in an...

The incidence of sudden cardiac arrest during participation in sports activities remains unknown. Preparticipation screening programs aimed at preventing sudden cardiac arrest during sports activities are thought to be able to identify at-risk athletes; however, the efficacy of these programs remains controversial. We sought to identify all sudden cardiac arrests that occurred during participation in sports activities within a specific region of Canada and to determine their causes. In this retrospective study, we used the Rescu Epistry cardiac arrest database (which contains records of every cardiac arrest attended by paramedics in the network region) to identify all out-of-hospital cardiac arrests that occurred from 2009 through 2014 in persons 12 to 45 years of age during participation in a sport. Cases were adjudicated as sudden cardiac arrest (i.e., having a cardiac cause) or as an event resulting from a noncardiac cause, on the basis of records from multiple sources, including ambulance call reports, autopsy reports, in-hospital data, and records of direct interviews with patients or family members. Over the course of 18.5 million person-years of observation, 74 sudden cardiac arrests occurred during participation in a sport; of these, 16 occurred during competitive sports and 58 occurred during noncompetitive sports. The incidence of sudden cardiac arrest during competitive sports was 0.76 cases per 100,000 athlete-years, with 43.8% of the athletes surviving until they were discharged from the hospital. Among the competitive athletes, two deaths were attributed to hypertrophic cardiomyopathy and none to arrhythmogenic right ventricular cardiomyopathy. Three cases of sudden cardiac arrest that occurred during participation in competitive sports were determined to have been potentially identifiable if the athletes had undergone preparticipation screening. In our study involving persons who had out-of-hospital cardiac arrest, the incidence of sudden cardiac

This presentation includes a brief overview of the corporate structure of Veridian Corporation and discusses the concept of customer choice and competition regarding the electric power industry in Ontario. Pricing and price stability was also discussed with reference to the outlook of electricity retailing. The Veridian holding company employs a total of 149 employees within its corporate structure which includes Veridian Energy Inc., Veridian Connections Inc. (a local electric distribution company), and Firstsource Inc. (an energy retailing business). Veridian operates in the Ontario cities of Pickering, Ajax, Clarington, and Belleville. The author notes that true customer choice occurs when customers have accurate price information before they buy a product, or when they have choice regarding who they buy the product from. Likewise, true competition occurs when there are multiple suppliers, when there is sufficient supply, and when prices are determined by demand. Although the electricity market in Ontario was opened to competition on May 1, 2002, customers do not really have a choice, nor does true competition exist. The author suggests that the Pickering generating station must be brought back on-line, as well as an investment climate that will attract new investors in power generation to Ontario. It was noted that government intervention is not helpful in stimulating investment in the power system. Pricing and price stability was discussed with reference to current trends in the import/export balance. The volatility in prices is expected to get worse in the near future, which is particularly detrimental to large power users who are seeking the assurance of a fixed price so that they could predict their production costs. 2 tabs., 4 figs.

Trauma is a leading cause of death worldwide with 5.8 million deaths occurring yearly. Almost 40% of trauma deaths are due to bleeding and occur in the first few hours after injury. Of the remaining severely injured patients up to 25% develop a dysregulated immune response leading to multiple organ dysfunction syndrome (MODS). Despite improvements in trauma care, the morbidity and mortality of this condition remains very high. Massive traumatic injury can overwhelm endogenous homeostatic mechanisms even with prompt treatment. The underlying mechanisms driving MODS are also not fully elucidated. As a result, successful therapies for trauma-related MODS are lacking. Trauma causes tissue damage that releases a large number of endogenous damage-associated molecular patterns (DAMPs). Mitochondrial DAMPs released in trauma, such as mitochondrial DNA (mtDNA), could help to explain part of the immune response in trauma given the structural similarities between mitochondria and bacteria. MtDNA, like bacterial DNA, contains an abundance of highly stimulatory unmethylated CpG DNA motifs that signal through toll-like receptor-9 to produce inflammation. MtDNA has been shown to be highly damaging when injected into healthy animals causing acute organ injury to develop. Elevated circulating levels of mtDNA have been reported in trauma patients but an association with clinically meaningful outcomes has not been established in a large cohort. We aimed to determine whether mtDNA released after clinical trauma hemorrhage is sufficient for the development of MODS. Secondly, we aimed to determine the extent of mtDNA release with varying degrees of tissue injury and hemorrhagic shock in a clinically relevant rodent model. Our final aim was to determine whether neutralizing mtDNA with the nucleic acid scavenging polymer, hexadimethrine bromide (HDMBr), at a clinically relevant time point in vivo would reduce the severity of organ injury in this model.

The aim of this study was to analyze the relationship between competitive anxiety and heart rate variability (HRV) in swimming athletes. A total of 66 volunteers (41 male and 27 female) who swam the 400-m freestyle in the Brazilian Swimming Championships participated. Thirty minutes before the 400-m freestyle event, the athletes answered the Competitive Anxiety Inventory (CSAI-2R) questionnaire, then underwent anthropometric (body weight, height, and skinfold thickness) and HRV measurements. Then, at a second meeting, held 3 h after the 400-m freestyle event, the athletes returned to the evaluation room for HRV measurement (Polar ® RS800cx, Kempele, Finland). Multiple linear regression was used to evaluate the relationship between competitive anxiety and HRV. The multiple linear regression was performed in three blocks (block 1: cognitive anxiety, block 2: somatic anxiety, and block 3: self-confidence), adopting the forward model. The results indicated a significant association between cognitive anxiety (p = 0.001) and HRV. An increased magnitude of the association was observed when somatic anxiety was inserted in the model (p = 0.001). In contrast, self-confidence showed, which was inserted in block 3, no relationship with HRV (p = 0.27). It was concluded that cognitive and somatic anxieties were associated with the HRV of swimmers. Athletes with a high magnitude of cognitive and/or somatic anxiety demonstrated more significant autonomic nervous system disturbance. Practically, psychological interventions are needed to improve anxiety states that are specific to perform well, and to improve HRV.

Full Text Available The aim of the paper is to analyze the competitiveness of the European textile and clothing industry under the influence of globalization and recent economic crisis. The textile and clothing industry is an important part of the European manufacturing industry, playing a vital role in the economy and social welfare in many regions of Europe. The European textile and clothing industry has undergone significant changes in recent decades due to the technological advances, developments in production costs, the emergence major international competitors and the elimination import quotas after 2005. In response to the competitive challenges, this sector of activity has undertaken a lengthy process of restructuring and modernization. Globalization and technological progress have led to rethinking the strategy of the companies in the industry. In a competitive global market, European organizations producing textiles and garments have as main competitive advantage research and continuous innovation. Using methods of qualitative research, this paper analyses the evolution of the main financial indicators concerning this sector of activity in the period 2007 – 2013, including domestic consumption, turnover, number of employees, number of companies, imports and exports. The globalization of markets, international outsourcing and development of the Internet had a major impact on the structure and dynamics of the textile and clothing industry in Europe, and in particular on small and medium enterprises. Also, relocation, subcontracting and outsourcing of large brands in this domain have contributed significantly to the increase of imports from low-cost countries. A growing number of apparel retailers have emerged on the market, organizing supply chains globally. At the same time, producers have transferred part of their activities to low-cost countries in order to maintain market competitiveness. This was determined by the major differences in salaries across

As the healthcare marketplace, characterized by declining revenues and heavy price competition, continues to evolve toward managed care, teaching hospitals are being forced to act more like traditional industrial organizations. Profit-oriented behavior, including emphases on market strategies and competitive advantage, is now a necessity if these hospitals are going to survive the transition to managed care. To help teaching hospitals evaluate strategic options that maximize financial effectiveness, this study examined the financial and operating data for 100 major U.S. teaching hospitals to determine relationships among competitive strategy, market environment, and financial return on invested capital. Results should help major hospitals formulate more effective strategies to combat environmental turbulence.
Approximate kernel competitive learning.
Wu, Jian-Sheng; Zheng, Wei-Shi; Lai, Jian-Huang
2015-03-01
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.

Full Text Available Starting from the major impact the organizational culture exerts over long-term performance of organizations and on the competitive advantage, in the theory and practice of management the concerns for understanding its multiple facets have intensified worldwide. This is highlighted by the numerous intercultural studies that emphasize the "invisible force" of each nation's culture and each organization's culture, which constitutes irrefutable arguments for enhancing the knowledge in this area. In this context, this study highlights how the cultural dimension "individualism-collectivism" influences the behavior of employees, in general, but especially that of managers from South-West Oltenia Region. The study results are based on the responses of 1086 respondents from 70 organizations in various fields of economic activity, whose opinions were investigated in two perspectives: current practice and desired practice. This paper presents some of the findings resulted from the research COMOR- Managerial Behavior in the Organizations in Romania, initiated and carried out throughout the country since 2009 by the Management Scientific Society of Romania (SSMAR in collaboration with the Association of Faculties of Economics in Romania (AFER.

Wholesale political, economic, and social change is pressuring health-care organizations to reinvent themselves as they enter a new arena of managed competition. Survival is at stake. Will belt-tightening efforts, combined with structural changes and strategic alliances, achieve the necessary improvements in efficiency and help to secure an adequate patient base? It seems reasonable to expect that health-care institutions can realize the major gains in quality, productivity, efficiency, and competitive edge that organizations in the manufacturing and service industries have enjoyed for the past several years. It seems like a logical next step for health-care organizations to deploy proven methods--such as work redesign, team-based structures, and empowered workforces--that have helped to restore competitiveness to many industrial and service firms. This article describes how to organize teams at all levels and accelerate their development to achieve important organizational objectives--such as improving quality, productivity, and efficiency--while increasing employee satisfaction. Pioneering workplace innovations are reviewed to demonstrate how high-involvement teams integrating strategic planning, research, and health-care delivery processes are not only possible but highly desirable. Enhanced quality, improved productivity, greater efficiency, and employee satisfaction all translate to an undeniable competitive advantage.
Predators and prey: a new ecology of competition.
Moore, J F
1993-01-01
Much has been written about networks, strategic alliances, and virtual organizations. Yet these currently popular frameworks provide little systematic assistance when it comes to out-innovating the competition. That's because most managers still view the problem in the old way: companies go head-to-head in an industry, battling for market share. James Moore sets up a new metaphor for competition drawn from the study of biology and social systems. He suggests that a company be viewed not as a member of a single industry but as a part of a business ecosystem that crosses a variety of industries. In a business ecosystem, companies "co-evolve" around a new innovation, working cooperatively and competitively to support new products and satisfy customer needs. Apple Computer, for example, leads an ecosystem that covers personal computers, consumer electronics, information, and communications. In any larger business environment, several ecosystems may vie for survival and dominance, such as the IBM and Apple ecosystems in personal computers or Wal-Mart and K mart in discount retailing. In fact, it's largely competition among business ecosystems, not individual companies, that's fueling today's industrial transformation. Managers can't afford to ignore the birth of new ecosystems or the competition among those that already exist. Whether that means investing in the right new technology, signing on suppliers to expand a growing business, developing crucial elements of value to maintain leadership, or incorporating new innovations to fend off obsolescence, executives must understand the evolutionary stages all business ecosystems go through and, more important, how to direct those changes.

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.

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.

We study how competition in the mutual fund industry affects stock market liquidity. We argue that mutual fund families operate as multi-product firms, jointly choosing fees, performance and number of funds and sharing common research facilities. The family-based organization generates economies of scale in information that induce a trade off between performance and number of funds. The presence of more and relatively less-informed funds impacts the market, increasing stock liquidity. This in...

In 2013, the level of tourism competitiveness presented by APEC, ranged between 6 and 82 position globally and only 53% of the 19 APEC economies that were evaluated by the World Economic Forum (WEF, improved their level of competitiveness. In relation to the regulatory framework linked to tourism, nations like Peru, Brunei and Russia reached the lowest ratings of the block thus have enormous work to do to improve your score in this category. In business environment and infrastructure, highlighted America. While in human and cultural resources, proved to be the issue in which APEC economies outperformed. Finally, results for APEC economies, evidence that critical areas are those concerning regulation and policies; and particularly sustainability issue, which can become a bottleneck in terms of competitiveness in the area of APEC therefore must strengthen and design better strategies for joint efforts in relation to such matters.
Open energy management systems as a tool for competition

Energy Management Systems (EMSs) have been called the nerve center for an electric utility. These systems have the capacity to monitor the electrical grid by retrieving tens of thousands of MW/MVar flows, voltages and breaker/switch positions every few seconds. With data interchange agreements utilities can also monitor performance of neighboring systems. System dispatchers need to access more and more information sources and their job is becoming more complicated. Other departments need to access EMS related data and work more closely with system dispatch. To date, the role of Energy Management Systems has not been affected significantly by the prospect of competition. With the clean air act, emission allowance trading, open transmission access, and potential for customer choice it is likely that Energy Management Systems will play a more strategic business role in the future. In particular, Open Energy Management Systems that allow the utility the freedom to select applications from multiple vendors will have special advantages. This paper will address potential areas, where an Open Energy Management System can be used to obtain a competitive edge. It will also outline how competition is likely to affect Energy Management System architectures and procurement practices

Full Text Available Renal cell carcinoma (RCC occupies one of the leading places in the world for morbidity among malignant neoplasms of the genitourinary system. The frequency of occurrence of bilateral RCC according to different authors is 2–6% of the total population of patients with RCC. Currently, the only effective method of treatment of bilateral RCC is surgical treatment. Patients with bilateral RCC are at high risk of dev eloping of local recurrence or progression of the disease after organ-preserving surgeries, which is why the surgeon is faced with a choice between a high risk of developing renal failure or relapse and/or progression of the disease, depending on the extent of the surgical intervention. According to the literature, in patients with bilateral RCC there was an increase in the incidence of papillary variant of RCC up to 19% and the presence of multifocal lesion. Surgical treatment of bilateral RCC is the only effective method to achieve satisfactory oncological results at a low incidence of complications. The m ost justified option for the treatment of bilateral RCC is the implementation of bilateral organ-preserving treatment, which allows achieving the optimal functional results. This article presents a clinical case of successful surgical treatment of a patient with bilateral RCC with multiple tumors.

Full Text Available In light of the recent macroeconomic instability in global markets, we examine the evolution of competitive dynamics and firm profitability when industries are subject to recessions. Although ordinary intuition leads most to view recessions as harmful, we highlight conditions under which they enhance the relative value of industry-level supply-side isolating mechanisms, thereby affording early movers significant and sustainable profit advantages vis-à-vis laggards. We observe that the distribution of firm size within the industry switches from a bi-modal distribution (i.e., one dominated by both small and large firms to a right-skewed one (i.e., dominated mostly by large firms in these contexts, thereby signaling the rise of important opportunities in the form of less rivalrous competitive contexts for survivors of recessions. We derive our results from formal modeling and multiple simulation runs.

The elements of competitive environment are derived from “traditional” market structure characteristics, developed by the scholars of classical economics and modern microeconomics, with additional factors coming from industrial organization, theoretical oligopoly models, M. Porter’s five competitive forces and diamond. The developed set of the elements of competitive environment is applied for the comparative analysis of three Lithuanian oligopolic markets. The results obtained confirm the potential for practical application of the developed classification for similar analysis.Article in Lithuanian

The so-called 'TRIPS flexibilities' restated in 2001 by the World Trade Organization's Doha Declaration on TRIPS and Public Health offer a variety of policy avenues for promoting global price-based competition for essential medicines, and thus for improving access to affordable medicines in the developing world. In recent years, developing countries and international organisations alike have begun to explore the potentialities of global generic markets and competition generally, and also of using compulsory licensing to remedy anti-competitive practices (e.g. excessive pricing) through TRIPS-compatible antitrust enforcement. These and other 'pro-competitive' TRIPS flexibilities currently available provide the critical leverage and policy space necessary to improve access to affordable medicines in the developing world.

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

Wild hosts are commonly co-infected with complex, genetically diverse, pathogen communities. Competition is expected between genetically or ecologically similar pathogen strains which may influence patterns of coexistence. However, there is little data on how specific strains of these diverse pathogen species interact within the host and how this impacts pathogen persistence in nature. Ticks are the most common disease vector in temperate regions with Borrelia burgdorferi, the causative agent of Lyme disease, being the most common vector-borne pathogen in North America. Borrelia burgdorferi is a pathogen of high public health concern and there is significant variation in infection phenotype between strains, which influences predictions of pathogen dynamics and spread. In a laboratory experiment, we investigated whether two closely-related strains of B. burgdorferi (sensu stricto) showed similar transmission phenotypes, how the transmission of these strains changed when a host was infected with one strain, re-infected with the same strain, or co-infected with two strains. Ixodes scapularis, the black-legged tick, nymphs were used to sequentially infect laboratory-bred Peromyscus leucopus, white-footed mice, with one strain only, homologous infection with the same stain, or heterologous infection with both strains. We used the results of this laboratory experiment to simulate long-term persistence and maintenance of each strain in a simple simulation model. Strain LG734 was more competitive than BL206, showing no difference in transmission between the heterologous infection groups and single-infection controls, while strain BL206 transmission was significantly reduced when strain LG734 infected first. The results of the model show that this asymmetry in competition could lead to extinction of strain BL206 unless there was a tick-to-host transmission advantage to this less competitive strain. This asymmetric competitive interaction suggests that strain identity and

The aim of this study was to model the sorption and retention of Cd, Cu, Ni, Pb and Zn in soils. To that extent, the sorption and retention of these metals were studied and the soil characterization was performed separately. Multiple stepwise regression was used to produce multivariate models with linear techniques and with support vector machines, all of which included 15 explanatory variables characterizing soils. When the R-squared values are represented, two different groups are noticed. Cr, Cu and Pb sorption and retention show a higher R-squared; the most explanatory variables being humified organic matter, Al oxides and, in some cases, cation-exchange capacity (CEC). The other group of metals (Cd, Ni and Zn) shows a lower R-squared, and clays are the most explanatory variables, including a percentage of vermiculite and slime. In some cases, quartz, plagioclase or hematite percentages also show some explanatory capacity. Support Vector Machine (SVM) regression shows that the different models are not as regular as in multiple regression in terms of number of variables, the regression for nickel adsorption being the one with the highest number of variables in its optimal model. On the other hand, there are cases where the most explanatory variables are the same for two metals, as it happens with Cd and Cr adsorption. A similar adsorption mechanism is thus postulated. These patterns of the introduction of variables in the model allow us to create explainability sequences. Those which are the most similar to the selectivity sequences obtained by Covelo (2005) are Mn oxides in multiple regression and change capacity in SVM. Among all the variables, the only one that is explanatory for all the metals after applying the maximum parsimony principle is the percentage of sand in the retention process. In the competitive model arising from the aforementioned sequences, the most intense competitiveness for the adsorption and retention of different metals appears between

Full Text Available In a more transparent and dynamic world, in which consumers trust other consumers more for advice and recommendations on products and services, the continuity of organizations appears to be associated with socialization, the sharing of interests and the interaction with the audience. This is associated with the incorporation of digital technologies to business, specifically the use of social media. Consequently, it is timely and interesting to explore the phenomenon of virtual socialization, although it is a little-studied field and what is needed is an innovative and theoretical approach based upon theories of marketing and communication. Expertise in these areas is present in all organizations and their performance is important for appropriate development of them. This work is a qualitative analysis about the behavior, reactions and attitudes of individuals to organizations, in order to understand the social factors that contribute to sustainable competitive advantages of organizations which can support strategic and future actions. We conclude that relevant factors associated with the tacit knowledge of the organization, specifically to learning and social interaction of the organization and their knowledge of virtual communities. The higher the coexistence of factors, the more difficult is the replication and greater will be the hypothesis of sustainable competitive advantage.

The primary goal of the field concerned with organic semiconductors is to produce devices with performance approaching that of silicon electronics, but with the deformability—flexibility and stretchability—of conventional plastics. However, an inherent competition between deformability and charge transport has long been observed in these materials, and achieving the extreme (or even moderate) deformability implied by the word “plastic” concurrently with high charge transport may be elusive. This competition arises because the properties needed for high carrier mobilities—e.g., rigid chains in π-conjugated polymers and high degrees of crystallinity in the solid state—are antithetical to deformability. On the device scale, this competition can lead to low-performance yet mechanically robust devices, or high-performance devices that fail catastrophically (e.g., cracking, cohesive failure, and delamination) under strain. There are, however, some observations that contradict the notion of the mutual exclusivity of electronic and mechanical performances. These observations suggest that this problem may not be a fundamental trade-off, but rather an inconvenience that may be negotiated by a logical selection of materials and processing conditions. For example, the selection of the poly(3-alkylthiophene) with a critical side-chain length—poly(3-heptylthiophene) (n = 7)—marries the high deformability of poly(3-octylthiophene) (n = 8) with the high electronic performance (as manifested in photovoltaic efficiency) of poly(3-hexylthiophene) (n = 6). This review explores the relationship between deformability and charge transport in organic semiconductors. The principal conclusions are that reducing the competition between these two parameters is in fact possible, with two demonstrated routes being: (1) incorporation of softer, insulating material into a stiffer, semiconducting material and (2) increasing disorder in a highly ordered film, but not

The plants and their functional ingredients hold potential to cure various maladies and number of plants hold therapeutic potential. The present research was designed study the health promoting potential of black cumin (Nigella sativa) fixed oil (BCFO) and essential oil (BCEO) against oxidative stress with special reference to multiple organ toxicity. For the purpose, thirty rats (Strain: Sprague Dawley) were procured and divided into three groups (10 rats/group). The groups were fed on their respective diets i.e. D1 (control), D2 (BCFO @ 4.0%) and D3 (BCEO @ 0.30%) for a period of 56 days. Mild oxidative stress was induced with the help of potassium bromate injection @ 45 mg/Kg body weight. Furthermore, the levels of cardiac and liver enzymes were assayed. The results indicated that oxidative stress increased the activities of cardiac and liver enzymes. However, supplementation of BCFO and BCEO was effective in reducing the abnormal values of enzymes. Elevated levels of lactate dehydrogenase (LDH), CPK and CPK-MB were reduced from 456 to 231, 176 to 122 and 45 to 36mg/dL, respectively. Similarly, liver enzymes were also reduced. However, the results revealed that BCEO supplementation @ 0.30% is more effectual in ameliorating the multiple organ toxicity in oxidative stressed animal modelling. In the nutshell, it can be assumed that black cumin essential oil is more effective in reducing the extent of potassium bromate induced multiple organ toxicity (cardiac and liver enzymes imbalance) that will ultimately helpful in reducing the extent of myocardial and liver necrosis.
Improve global competitiveness with supply-chain management

Over the past 10 to 15 years, petrochemical companies have aggressively cut costs due to increased international competition. Unfortunately, these conditions will remain part of the future business environment. To remain international as players, leading chemical companies must develop new methods to keep a competitive edge. One option is to use global supply-chain management. With this strategy, organizations can optimize costs in an integrated fashion along the entire manufacturing and delivery system worldwide. This is a sharp contrast to previously used compartmentalized cost cutting by departments such as transportation, manufacturing, etc. Rethinking the supply-chain management requires devising a new order on how all manufacturing process costs contribute to the total product costs. Manufacturers can no longer look at operation segments as separate puzzle pieces. They must devise a framework that integrates all functions of production and distribution to be the lowest-cost manufacturer in that market
Competition between roots and microorganisms for nitrogen: mechanisms and ecological relevance.
Kuzyakov, Yakov; Xu, Xingliang
2013-05-01
Demand of all living organisms on the same nutrients forms the basis for interspecific competition between plants and microorganisms in soils. This competition is especially strong in the rhizosphere. To evaluate competitive and mutualistic interactions between plants and microorganisms and to analyse ecological consequences of these interactions, we analysed 424 data pairs from 41 (15)N-labelling studies that investigated (15)N redistribution between roots and microorganisms. Calculated Michaelis-Menten kinetics based on K(m) (Michaelis constant) and V(max) (maximum uptake capacity) values from 77 studies on the uptake of nitrate, ammonia, and amino acids by roots and microorganisms clearly showed that, shortly after nitrogen (N) mobilization from soil organic matter and litter, microorganisms take up most N. Lower K(m) values of microorganisms suggest that they are especially efficient at low N concentrations, but can also acquire more N at higher N concentrations (V(max)) compared with roots. Because of the unidirectional flow of nutrients from soil to roots, plants are the winners for N acquisition in the long run. Therefore, despite strong competition between roots and microorganisms for N, a temporal niche differentiation reflecting their generation times leads to mutualistic relationships in the rhizosphere. This temporal niche differentiation is highly relevant ecologically because it: protects ecosystems from N losses by leaching during periods of slow or no root uptake; continuously provides roots with available N according to plant demand; and contributes to the evolutionary development of mutualistic interactions between roots and microorganisms. © 2013 The Authors.

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.

The type VI secretion system (T6SS) is widespread in Gram-negative bacteria and can deliver toxic effector proteins into eukaryotic cells or competitor bacteria. Antibacterial T6SSs are increasingly recognized as key mediators of interbacterial competition and may contribute to the outcome of many polymicrobial infections. Multiple antibacterial effectors can be delivered by these systems, with diverse activities against target cells and distinct modes of secretion. Polymorphic toxins containing Rhs repeat domains represent a recently identified and as-yet poorly characterized class of T6SS-dependent effectors. Previous work had revealed that the potent antibacterial T6SS of the opportunistic pathogen Serratia marcescens promotes intraspecies as well as interspecies competition (S. L. Murdoch, K. Trunk, G. English, M. J. Fritsch, E. Pourkarimi, and S. J. Coulthurst, J Bacteriol 193:6057-6069, 2011, http://dx.doi.org/10.1128/JB.05671-11). In this study, two new Rhs family antibacterial effectors delivered by this T6SS have been identified. One of these was shown to act as a DNase toxin, while the other contains a novel, cytoplasmic-acting toxin domain. Importantly, using S. marcescens, it has been demonstrated for the first time that Rhs proteins, rather than other T6SS-secreted effectors, can be the primary determinant of intraspecies competition. Furthermore, a new family of accessory proteins associated with T6SS effectors has been identified, exemplified by S. marcescens EagR1, which is specifically required for deployment of its associated Rhs effector. Together, these findings provide new insight into how bacteria can use the T6SS to deploy Rhs-family effectors and mediate different types of interbacterial interactions. Infectious diseases caused by bacterial pathogens represent a continuing threat to health and economic prosperity. To counter this threat, we must understand how such organisms survive and prosper. The type VI secretion system is a weapon that

The presumed advantages of genetic recombinations are difficult to demonstrate directly. To investigate the effects of recombination and background heterozygosity on competitive ability, we have performed serial-transfer competition experiments between isogenic sexual and asexual strains of the yeast Saccharomyces cerevisiae. The members of these diploid pairs of strains differed only in being heterozygous (sexual) or homozygous (asexual) at the mating type or MAT locus. Competing pairs had either a completely homozygous or a heterozygous genetic background, the latter being heterozygous at many different loci throughout the genome. A round of meiotic recombination (automixis) conferred a large and statistically significant enhancement of competitive ability on sexual strains with a heterozygous genetic background. By contrast, in homozygous background competitions, meiosis decreased the sexual strains' initial relative competitive ability. In all cases, however, the sexual strains outcompeted their isogenic asexual counterparts, whether meiotic recombination had occurred or not. In some genetic backgrounds, this was due in part to an overdominance effect on competitive advantage of heterozygosity at the MAT locus. The advantage of the sexual strains also increased significantly during the course of the homozygous background competitions, particularly when meiosis had occurred. This latter effect either did not occur or was very weak in heterozygous background competitions. Overall, sexual strains with heterozygous genetic backgrounds had a significantly higher initial relative competitive ability than those with homozygous backgrounds. The advantage of mating type heterozygosity in this organism extends far beyond the ability to recombine meiotically. PMID:8570658

Full Text Available The World Trade Organization (WTO established a Working Group on the interaction between trade and competition policy in 1996. By the Doha Ministerial Declaration, it recognized the case for international competition policy framework and agreed that the relevant negotiations take place after the Fifth Session of the Ministerial Conference. The Working Group is meant to focus on the clarification of: core principles, including transparency, non-discrimination and procedural fairness among others in the period until the Fifth Session. This article attempts to clarify the implications of the core (WTO principles to the would-be international competition laws and practices. It further tries to get lessons from competition law and practices of the European Community. Protection of fundamental rights, proportionality, non-discrimination, transparency, supremacy, subsidiarity and direct effect are the general principles of the European Community law to be discussed in relation to the competition law and policy. It concludes that the general principles of the WTO and EC laws provide guiding principles for the future international competition norms, and makes some preliminary assessment of the present Korean competition law and policy in the light of those principles.
