  1. THE RELEVANT TEMPORAL MARKET DEFINITION IN ANTITRUST ANALYSIS

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available The purpose of the paper is to compare various theoretical approaches to the relevant temporal market definition, collecting the arguments for their implementation under the different kinds of antitrust cases. It is vital for the markets with peak demand (transport, electricity, markets of intergenerational products or discreet supply (agriculture. Methodology. The survey is based on the theoretical and graphical modelling of product space perception by consumers. It investigates changes of the latter under different marketing strategies of a seller. Statistical methods are used to analyse trends of demand and prices for iPhones’ changes, as well as dynamics of electricity consumption. Results. The paper reveals two facing approaches to the definition of relevant temporal market: 1 the discrete one that provides a short-run analysis of products’ substitutability and combines only those time periods that are characterized by a stable balance of demand and supply, as well as stable market equilibrium; 2 the coherent one that provides a long-run analysis of cyclical variation of the market. This cycling is based on the awareness of consumers and producers of intertemporal substitutability of products. The authors use the model of intertemporal competition to explain principles of these approaches and apply it to the iPhone market analysis. They conclude that the coherent approach must be applied to the temporal market definition for the products with elastic demand. Inelastic demand brings the necessity to apply the discrete approach to the temporal market definition. These conclusions cannot be applied to regulated markets. The system of government regulation is the main determinant of the temporal boundaries of such markets. Practical implications. The results of this research can be used by competition agencies in antitrust cases to define the relevant temporal market, where the violations of antitrust legislation can occur. The correct

  2. How Federal Antitrust Principles Would Impact the Insurance Ratemaking Function

    OpenAIRE

    Youssef I. Kouatly; Iskander S. Hamwi

    1992-01-01

    This study focuses on basic federal antitrust principles and their potential impact on property and liability insurance ratemaking. The authors believe that, in view of the growing debate around the issue of repeal or amendment of the McCarran Act, it has become necessary to focus more fully on the impact of such a potential change in the antitrust exemption accorded the business of insurance under the Act. In addition to ratemaking technicalities, state legislatures and regulators should be ...

    This report updates and augments an earlier report that cataloged antitrust license conditions resulting from the Nuclear Regulatory Commission's (NRC's) antitrust review process mandated by the 1970 antitrust amendments from December 1970 to April 1976. An overview of the NRC's antitrust review process relevant to applications for construction permits and operating licenses is presented. Information on the antitrust reviews completed from May 1976 to February 1978 is also given. This information includes the identity of applicants, utility system and unit sizes, the geographic location of the applicant, and a summary of any antitrust license conditions

  6. Determination of the relevant market as a criterion of assessment of concentration effects in the practice of antitrust authorities

    Directory of Open Access Journals (Sweden)

    Daria Kostecka-Jurczyk

    2012-12-01

    Full Text Available Determining the relevant market is the first and the most important step in antimonopoly proceedings due to the fact that the market position of an enterprise is always determined from the relevant market perspective. In respect of mergers, establishing the relevant market is essential in analysing whether the aim of the concentration is to distort and limit competition on the market. The author of the article focuses on describing methods for determining the relevant market applied by antimonopoly authorities.

  7. Recent Trends in Antitrust Enforcement

    Directory of Open Access Journals (Sweden)

    Mario Siragusa

    2015-10-01

    Full Text Available This article intends to discuss a selection of the most relevant features of the most recent trends in antitrust enforcement. Firstly, anticompetitive signalling will be addressed: its assessment depends on the kind of information provided. Where such information is of public knowledge or is very well known by the market participants, signalling should not be deemed as anticompetitive. Secondly, the Power Cable case has raised for the first time various problematic issues, such as the possibility to impose parental liability on a purely financial investor, even where the presumed direct infringer would have been able to pay the fine. This appears to be irreconcilable with the objectives for which the case law on parental liability has been elaborated. Thirdly, as to the concept of restriction of competition by object, it is argued that the Intel case does not disavow the principles established in Cartes Bancaires. Indeed, the finding of a violation and the different methodology applied in the first case are only due to its specific factual circumstances. Finally, the nouvelle vague of the case law on the anticompetitive abuse of rights has led to two opposite approaches, one at the EU and the other at the Italian level. The first one, based on the finding of objective circumstances, is perfectly consistent with existing EU case law, while the second, exclusively focused on the exclusionary intent, seems to be in sharp contrast with it. The hope is that the Court of Justice will intervene to resolve this contradiction.

  8. Ecological principles relevant to nuclear war

    International Nuclear Information System (INIS)

    Hutchinson, T.C.; Cropper, W.P. Jr.; Grover, H.D.

    1985-01-01

    The ecological principles outlined are very basic ones; the authors anticipate a readership trained in a broad range of disciplines, including those unfamiliar with the academic discipline of ecology. The authors include substantial discussion on ecophysiology (i.e., the responses of organisms to their environment) because this is relevant to the new understanding of the potential climatic consequences of nuclear war. In particular, the physiological sensitivity of organisms to reduced levels of light and temperature are a key part of the analysis of the potential ecological effects and agricultural effects of nuclear war. Much of the ecological analysis has been organized around major biological units called biomes. The authors describe the biome concept and discuss some of the environmental-climatic factors that are believed to control biome distribution. Emphasis is given to plants because of their controlling influence on ecosystem functions through their role as primary producers. Future reports are needed to address more fully the potential effects on animals. Much more research needs to be done on both plant and animal responses to the types of perturbations possible for the aftermath of a nuclear war. Another important element for analysis of the potential ecological consequences of nuclear war concerns recovery processes. As the post-nuclear war environmental extremes ameliorate, ecological communities in devastated regions would begin to reorganize. It is not possible to predict the course of such a succession precisely, but some principles concerning post-perturbation replacement (such as seed banks and germination), relevant successional patterns, and organism strategies are discussed

    Competition law - or antitrust law, as it is called in the United States - is a field of law to which economic concepts, such as "restriction of competition" and "anti-competitive effect", are of central importance. This thesis analyses a number of such concepts, both from an economic and a legal

  10. Stricter antitrust legislation?

    International Nuclear Information System (INIS)

    Heller, W.

    2007-01-01

    In November 2006, the German Federal Ministry of Economics sent a ministerial draft bill on combating price abuses in the energy supply and food trade sectors to the trade associations for comment. The bill must be seen as part of a set of measures of the federal government seeking to improve conditions for more competition in the energy sector. An omnibus law is to add a new Section 29 to the Act against Restrictions on Competition (Antitrust Act). The addition is to bear the heading of 'Power Economy' and has been designed to prevent a utility (vendor of electricity, gas, and district heat) from abusing its position on a market which it dominates either alone or together with other utility companies. Depending on the interests involved, comments on the draft bills differ. On the whole, this tightening up of antitrust legislation is preceived more as a repair job. Stricter antitrust provisions absolutely must also be seen in their European dimension. European firms not falling under this stricter antitrust law enjoy advantages over German firms. (orig.)

    Neuroethics applies cognitive neuroscience for prescribing alterations to conceptions of self and society, and for prescriptively judging the ethical applications of neurotechnologies. Plentiful normative premises are available to ground such prescriptivity, however prescriptive neuroethics may remain fragmented by social conventions, cultural ideologies, and ethical theories. Herein we offer that an objectively principled neuroethics for international relevance requires a new meta-ethics: understanding how morality works, and how humans manage and improve morality, as objectively based on the brain and social sciences. This new meta-ethics will simultaneously equip neuroethics for evaluating and revising older cultural ideologies and ethical theories, and direct neuroethics towards scientifically valid views of encultured humans intelligently managing moralities. Bypassing absolutism, cultural essentialisms, and unrealistic ethical philosophies, neuroethics arrives at a small set of principles about proper human flourishing that are more culturally inclusive and cosmopolitan in spirit. This cosmopolitanism in turn suggests augmentations to traditional medical ethics in the form of four principled guidelines for international consideration: empowerment, non-obsolescence, self-creativity, and citizenship.

  18. Antitrust rules and Intellectual Property Rights in the EU and the US – Towards convergence?

    Directory of Open Access Journals (Sweden)

    Mario Todino

    2014-07-01

    Full Text Available In light of the exponential increase of the number of investigations raising the issue of how to reconcile competition rules and Intellectual Property Rights (IPRs, it is now clear that the area of Antitrust/IP intersection is becoming the battleground of antitrust enforcers around the Globe. In some areas inherently prone to market power accumulation, antitrust rules tend to clash with IPRs and prevail over the latter, for the intensity in the application of competition rules increasingly depends on the strength of the IPRs at stake, as well as on the sector involved. Information Communication Technology and Pharmaceuticals are the sectors most affected by this trend, as they both display specific market features calling for intensive antitrust scrutiny. Surprisingly enough, in these areas the EU and the US agencies are heading towards convergence, in light of the decisions taken in cases such as the judicial injunctions sought by FRAND-pledged SEPs holders and the reverse settlements in the Pharma sector. The purpose of this article is to show that in those areas more exposed to tension between antitrust and IP rules, there is an increasing level of convergence between the US and the EU. In particular, it is submitted that, like in the EU, the US is departing from the traditional symmetry principle under which antitrust rules are applied to IPRs exactly the same way as other property rights. In this new framework, inconsistency is more likely to come from the enforcement activity of NCAs across Europe.

  5. Relevance of Spiritual Principles for Resolving Social Problems

    Directory of Open Access Journals (Sweden)

    Ashok Natarajan

    2016-05-01

    Full Text Available Society unknowingly follows the course of spiritual evolution. Spirituality is the quest for self-existent order and harmonious perfection. The evolution of society is driven by an irrepressible aspiration for the values that are the translation and embodiment of that order. The history of civilization is a record of its progressive emergence. Spirituality is the quest for a unifying reality that transcends all limitations, distinctions and differences; an inner oneness that unites rather than divides us; a faith in and quest for perfection in all its myriad forms; and a power accessible to human beings to overcome impossible obstacles and achieve the inconceivable. It is founded on the principles of absolute freedom, equality and unity. In the modern era, faith in spirit is embodied in the realization of the intrinsic value, extraordinary endowments and unmanifest potentials of the human being. We find expressions of it in the idealism and power released by revolutionary social change. We revere its power in great individuals. The aspiration for perfection in any form or field of endeavor is spiritual. So also we recognize expressions of spirit in the movements of the masses. Spirituality is not confined to pursuit of the otherworldly or unattainable. It is a living power for the transformation of human consciousness and the solution to the compelling challenges confronting humanity.

  6. The principle of equivalence reconsidered: assessing the relevance of the principle of equivalence in prison medicine.

    Science.gov (United States)

    Jotterand, Fabrice; Wangmo, Tenzin

    2014-01-01

    In this article we critically examine the principle of equivalence of care in prison medicine. First, we provide an overview of how the principle of equivalence is utilized in various national and international guidelines on health care provision to prisoners. Second, we outline some of the problems associated with its applications, and argue that the principle of equivalence should go beyond equivalence to access and include equivalence of outcomes. However, because of the particular context of the prison environment, third, we contend that the concept of "health" in equivalence of health outcomes needs conceptual clarity; otherwise, it fails to provide a threshold for healthy states among inmates. We accomplish this by examining common understandings of the concepts of health and disease. We conclude our article by showing why the conceptualization of diseases as clinical problems provides a helpful approach in the delivery of health care in prison.

    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.

    The WHO Global Code of Practice on the International Recruitment of Health Personnel provides for guidance in health workforce management and cooperation in the international context. This article aims to examine whether the principles of the voluntary WHO Global Code of Practice can be applied to trigger health policy decisions within the EU zone of free movement of persons. In the framework of the Joint Action on European Health Workforce Planning and Forecasting project (Grant Agreement: JA EUHWF 20122201 (see healthworkforce.eu)), focus group discussions were organised with over 30 experts representing ministries, universities and professional and international organisations. Ideas were collected about the applicability of the principles and with the aim to find EU law compatible, relevant solutions using a qualitative approach based on a standardised, semi-structured interview guide and pre-defined statements. Based on implementation practices summarised, focus group experts concluded that positive effects of adhering to the Code can be identified and useful ideas-compatible with EU law-exist to manage intra-EU mobility. The most relevant areas for intervention include bilateral cooperations, better use of EU financial resources, improved retention and integration policies and better data flow and monitoring. Improving retention is of key importance; however, ethical considerations should also apply within the EU. Compensation of source countries can be a solution to further elaborate on when developing EU financial mechanisms. Intra-EU circular mobility might be feasible and made more transparent if directed by tailor-made, institutional-level bilateral cooperations adjusted to different groups and profiles of health professionals. Integration policies should be improved as discrimination still exists when offering jobs despite the legal environment facilitating the recognition of professional qualifications.

    A key point in the examination of the legality of antitrust practices is the delimitation of the relevant markets where the economic relations object of the analysis take place. This is the basis for the evaluation of the market power of the agents involved and the possible harm to competition they may cause. This work offers a study of the criteria for the determination of the relevant market in the scope of the natural gas industry in Brazil. It aims at identifying the performance of the agencies taking part in the Brazilian Antitrust System (SBDC) with regards to the examination of the related antitrust practices. These agencies work in connection with the National Petroleum, Natural Gas and Biofuels Regulatory Agency (ANP), which is responsible for issuing technical reports on the subjects related to its area of competence. The analysis presented here has the main goal of verifying if the most important technical, operational and legal aspects are being adequately considered by the SBDC and ANP in the definition of the relevant markets as a basis for the judgment of the antitrust practices, and if they are coherent with the principles for fostering economic competition. The results points out that, despite the successful cooperation between the SBDC and the ANP, there are the used definition of the relevant markets for the natural gas industry still needs refinement.

    A retrospective survey of the prevalence of TORCH infections among pregnant women was performed in the perinatal center, M. A. Tverye Military Sanitary Unit Nine (Perm), in June 2010 to December 2013. The survey covered 2060 women: they were all examined for cytomegalovirus, herpes simplex virus, and Toxoplasma. Antibodies to Toxoplasma gondii were detected in 28.68% (591/2060); 98.62% were found to have antibodies to herpes simplex; antibodies to cytomegalovirus were identified in 87.13% (1795/2060). Acute maternal toxoplasmosis was diagnosed by seroconversion or determination of IgM anti-Toxoplasma gondii antibodies, in the presence of a low avidity index and a four-fold increase in antibody titers, by simultaneously studying paired serum samples obtained at a 2-week interval. To confirm fetal infection, amniotic fluid PCR examination should be performed after 18 weeks' gestation. No consensus of opinion as to the principles of treatment for toxoplasmosis in pregnant women makes relevant the long-term results of antibacterial and antiprotozoal treatment cycles varying in duration and intensity. The prevention of acute toxoplasmosis in pregnant women ensures the principle of a mother's personal responsibility for infection safety of a newborn infant, which is informationally provided in health and safety fundamentals course and pregravid preparation schools.

  6. Sharing, samples, and generics: an antitrust framework.

    Science.gov (United States)

    Carrier, Michael A

    Rising drug prices are in the news. By increasing price, drug companies have placed vital, even life-saving, medicines out of the reach of consumers. In a recent development, brand firms have prevented generics even from entering the market. The ruse for this strategy involves risk-management programs known as Risk Evaluation and Mitigation Strategies ("REMS"). Pursuant to legislation enacted in 2007, the FDA requires REMS when a drug's risks (such as death or injury) outweigh its rewards. Brands have used this regime, intended to bring drugs to the market, to block generic competition. Regulations such as the federal Hatch-Waxman Act and state substitution laws foster widespread generic competition. But these regimes can only be effectuated through generic entry. And that entry can take place only if a generic can use a brand's sample to show that its product is equivalent. More than 100 generic firms have complained that they have not been able to access needed samples. One study of 40 drugs subject to restricted access programs found that generics' inability to enter cost more than $5 billion a year. Brand firms have contended that antitrust law does not compel them to deal with their competitors and have highlighted concerns related to safety and product liability in justifying their refusals. This Article rebuts these claims. It highlights the importance of samples in the regulatory regime and the FDA's inability to address the issue. It shows how a sharing requirement in this setting is consistent with Supreme Court caselaw. And it demonstrates that the brands' behavior fails the defendant-friendly "no economic sense" test because the conduct literally makes no sense other than by harming generics. Brands' denial of samples offers a textbook case of monopolization. In the universe of pharmaceutical antitrust behavior, other conduct--such as "pay for delay" settlements between brands and generics and "product hopping" from one drug to a slightly modified

  8. Competition policy in patent cases and antitrust.

    Science.gov (United States)

    Sobel, Gerald

    2003-01-01

    The article that follows examines the competition policy reflected in the decisions of the Court of Appeals for the Federal Circuit in its patent cases. The court's views on this subject have been manifested most plainly in decisions that have transformed the law concerning infringement under the doctrine of equivalents and claim construction. In both categories, the court narrowed patent scope by reason of its desire to protect competitors. The article argues that the court's premise in prescribing narrower claim scope reflected an incomplete view of competition policy. The court's analysis overlooked the benefits to competition provided by patents, which stimulate inventions and their development. The article traces the development of antitrust jurisprudence and demonstrates how respect for the contribution of patents to competition and skepticism of free-riding has evolved, particularly beginning in the 1970s. The article draws a parallel between the Court's reasoning about competition policy, on the one hand, and the rejected views of Justices Hugo Black and William O. Douglas and abandoned patent-antitrust jurisprudence, on the other. The Federal Circuit's decision in Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., Ltd., 234 F.3d 558 (Fed. Cir. 2000), on the subject of equivalents is considered in the paper. In that decision, the majority adopted a new rule that completely barred infringement under the doctrine of equivalents of any claim limitation where, in prosecution, there had been a narrowing amendment relating to patentability. In the past, prosecution estoppel foreclosing equivalents had been subject to a "flexible bar," which, in some circumstances, allowed for equivalence notwithstanding such an amendment. The article points out that because almost all patents are amended during prosecution, the effect would be to allow widespread copying of patented inventions by trivial modifications of any narrowed claim limitation.

    In this chapter, we begin our discussion of antitrust economics by considering what many consider its most central element: its ban on "price fixing" - that is, agreements among competitors over the prices they will charge or the outputs they will produce. Indeed, the prohibition on price fixing is one area of antitrust law that even those generally skeptical of governmental compe- tition policy typically regard approvingly. Nevertheless, despite its current uncontroversial status, we shall s...

  12. Incorporating sustainable development principles in the governance of Dutch domestic tourism. The relevance of boundary judgments

    Energy Technology Data Exchange (ETDEWEB)

    Bressers, H.; Dinica, V.

    2008-08-14

    survey revealed that among such 'insiders' the support for sustainable tourism governance and policies was generally much larger than the positions their organizations take in practice until now. Large majorities prove in favor of some form of national coordination and of the application of national policy instruments to guide subnational policy and planning, though most prefer rather weak instruments. We investigate what backgrounds explain to what extent such opinions are held. On the one hand we discern the growth and protection orientations. These are linked to the concern for environmental and nature impacts of tourism and the desire to capture a share of international tourism growth. These orientations have a clear link with the nature of the organizations the respondents are part of. On the other hand we investigate the relation with the perception of the domain of 'sustainable tourism'. What policy subfields are regarded as relevant for 'sustainable tourism'? Interpretation of what sustainable tourism is all about is an aspect of problem perception that in principle can frame a lot of other relevant perceptions and opinions. On the issue of these so-called 'boundary judgments' we see substantial differences among the respondents too. Divergent boundary judgments can impede any attempt to develop more coordinated governance and more coherent policies. The two most important dimensions (or 'factors') among the boundary judgments are again one that loads predominantly on growth related aspects and one that loads predominantly on protection related aspects. While there are correlations between the boundary judgments and the orientations, they are far from identical. Both orientations and boundary judgments seem to contribute to the explanation of opinions on governance of the tourism sector and instruments for sustainable tourism. This provides an interesting extra opportunity to influence the debate. While there is a

  13. Competitive bidding might create antitrust problems

    International Nuclear Information System (INIS)

    Smith, D.J.

    1991-01-01

    With the increased use and complexity of competitive bidding systems for new generating capacity there is the possibility that federal antitrust laws may be violated. Anyone violating Section 1 of the Sherman Act could face stiff penalties. Falling into this category of violations are agreements among competitors, price fixing, and elimination of competitors through the allocations of customers and/or territories. It does not have to be in writing for someone to be charged with bid rigging. In fact, it is stated that bid rigging is typically proved from the testimony of one of the persons involved. According to this paper, a charge of rigging the bids can come from: One or more bidders offering to provide power at a higher price than another bidder. Two or more bidders offering to supply power at the same price. One or more potential bidders not submitting a bid or intentionally bidding high. One bidder and not the others offering a more favorable construction schedule or an alternative proposal. One firm offering to renegotiate if its bid is rejected while the other bidders refuse. These are just some of the agreements that are illegal. The penalties for such violations of the Sherman Act are severe: fines of up to $100,000 and up to three years in jail for individuals; up to $1 million in fines for corporations

    In order to face the challenges in healthcare this century, it is essential that surgeons understand modern leadership principles. One of the greatest leaders in history was Dr. Martin Luther King, Jr., who provides a shining example of level-5 leadership for us to study. The study of leadership principles of great leaders can provide us with practical methods of conflict resolution as well as inspiration to keep us engaged and focused. As leaders of the medical community, we face numerous challenges, including discovering and implementing new treatments for disease, providing care for the indigent, overcoming educational challenges such as incorporating the ACGME Core Competencies into our surgical training and promoting diversity in education. Achieving these goals is often hindered by the environment in which we labor-nearly 50 million are uninsured, the rising cost of medical care is currently at 16% of the GNP, and reimbursement rates are falling-which makes the practice of surgery a significant challenge. Effective leadership will be paramount in achieving these goals. In this editorial, which summarizes a presentation given to the Surgical Section of the annual National Medical Association meeting, five important leadership principles that are important for surgeons have been selected and related to the outstanding leadership of Dr. Martin Luther King, Jr.

    Full Text Available In order for the concept of the market to play a significant and non-contradictory role in economic (and antitrust analysis, two conditions must be fulfilled. First, the characteristics of demand must be such as to demarcate a market unequivocally. Second, the competition in a specific market must have limited interaction with the rest of the economy. In general, these conditions cannot be met. First, the non-constancy of the elasticity of the demand function means that the size of the market depends on its structure and on the behaviour of its agents. Second, given differentiated products, the competitive relations between them will be heterogeneous, giving rise to as many market segments as there are individual products. Third, supply-side substitutability, i.e. the possibility of using a given technique to produce several products (not all in the same market ensures that intra-industry economic dynamics prevail over intra-market ones. Finally, multi-market contacts between firms generate overall strategic conduct, making analysis of any particular market irrelevant.  JEL Codes: K21, L40

    Meeks, J.E.

    1996-04-01

    Direct regulation of public utility activity and behavior has been the predominant approach to protect the public interest in this country. Changes in technology, as well as new thinking about the optimum role of regulation, have created a changing atmosphere in all of the traditional public utility industries. Competitive markets for many of the products and services in these industries have been developing. While monopoly power will continue to exist in certain parts of these industries and require direct regulation, in many areas a growing reliance upon competition as the best method of serving the public interest is developing. With this shift in emphasis from regulation to free markets, the antitrust laws take on new importance for these industries. In the absence of direct regulator control, those laws are society's primary method of insuring the markets necessary to make competition an effective device for protecting the public interest. This study provides an overview of the antitrust laws, briefly describes the applicable theoretical underpinnings, and then turns to areas where public utility activity may pose special problems or conflicts with prevailing antitrust policy

  11. Incorporating health care quality into health antitrust law

    Science.gov (United States)

    2008-01-01

    Background Antitrust authorities treat price as a proxy for hospital quality since health care quality is difficult to observe. As the ability to measure quality improved, more research became necessary to investigate the relationship between hospital market power and patient outcomes. This paper examines the impact of hospital competition on the quality of care as measured by the risk-adjusted mortality rates with the hospital as the unit of analysis. The study separately examines the effect of competition on non-profit hospitals. Methods We use California Office of Statewide Health Planning and Development (OSHPD) data from 1997 through 2002. Empirical model is a cross-sectional study of 373 hospitals. Regression analysis is used to estimate the relationship between Coronary Artery Bypass Graft (CABG) risk-adjusted mortality rates and hospital competition. Results Regression results show lower risk-adjusted mortality rates in the presence of a more competitive environment. This result holds for all alternative hospital market definitions. Non-profit hospitals do not have better patient outcomes than investor-owned hospitals. However, they tend to provide better quality in less competitive environments. CABG volume did not have a significant effect on patient outcomes. Conclusion Quality should be incorporated into the antitrust analysis. When mergers lead to higher prices and lower quality, thus lower social welfare, the antitrust challenge of hospital mergers is warranted. The impact of lower hospital competition on quality of care delivered by non-profit hospitals is ambiguous. PMID:18430219

  12. Addressing Pricing Power in Integrated Delivery: The Limits of Antitrust.

    Science.gov (United States)

    Berenson, Robert

    2015-08-01

    Prices are the major driver of why the United States spends so much more on health care than other countries do. The pricing power that hospitals have garnered recently has resulted from consolidated delivery systems and concentrated markets, leading to enhanced negotiating leverage. But consolidation may be the wrong frame for viewing the problem of high and highly variable prices; many "must-have" hospitals achieve their pricing power from sources other than consolidation, for example, reputation. Further, the frame of consolidation leads to unrealistic expectations for what antitrust's role in addressing pricing power should be, especially because in the wake of two periods of merger "manias" and "frenzies" many markets already lack effective competition. It is particularly challenging for antitrust to address extant monopolies lawfully attained. New payment and delivery models being pioneered in Medicare, especially those built around accountable care organizations (ACOs), offer an opportunity to reduce pricing power, but only if they are implemented with a clear eye on the impact on prices in commercial insurance markets. This article proposes approaches that public and private payers should consider to complement the role of antitrust to assure that ACOs will actually help control costs in commercial markets as well as in Medicare and Medicaid.

    Full Text Available In light of the slow modernization of the Italian large-scale food distribution sector, of the fragmentation at national level, of the significant roles of the cooperatives at local level and of the alliances between food retail chains, the ICA during the recent years has developed a strong interest in this sector.After having analyzed the peculiarities of the Italian large-scale food distribution sector, this article shows the recent approach taken by the ICA toward the main antitrust issues in this sector.In the analysis of such issues, mainly the contractual relations between the GDO retailers and their suppliers, the introduction of Article 62 of Law no. 27 dated 24th March 2012 is crucial, because, by facilitating and encouraging complaints by the interested parties, it should allow the developing of normal competitive dynamics within the food distribution sector, where companies should be free to enter the market using the tools at their disposal, without undue restrictions.

  7. Analysis of antitrust activity in the coal industry: 1964-1974

    Energy Technology Data Exchange (ETDEWEB)

    Hinson, W.R.

    1975-01-01

    Antitrust activity in the coal industry from 1964 to 1974 is studied for two major areas: 1) acquisitions and mergers, which involve the structure of the industry; and 2) price fixing, bid rigging, and customer allocations, which deal with the behavior of the industry. The government is criticized for the lack of antitrust activity during this time period. Offences of the antitrust laws by suppliers of fuel could have a chain-reaction effect on all commodity prices, because artificially high fuel prices could force other industries to increase their prices. Several recommendations are made: 1) a special section in both the Justice Department and the Federal Trade Commission should be established to handle violations of the antitrust laws occurring in the ''energy market''; 2) nolo contendere pleas and other forms of a consent settlement should be denied as an option for any energy concern accused of transgressing the antitrust laws; 3) all known coal reserves in the U.S. should be rationalized and placed under the supervision of the Federal Energy Administration; 4) a National reporting system for the ownership of coal reserves should be established; and 5) public regulatory commissions should be encouraged to order electric utilities to file private suits when anti-competitive conduct is suspected by coal suppliers.

  10. Principle of an operational complexity index for the characterization of the human factor relevance of future reactors concepts

    International Nuclear Information System (INIS)

    Papin, Bernard

    2004-01-01

    With the increasing reliability of the modern technological systems, the human contribution to the global risk in the operation of industrial systems is becoming more and more significant : in the nuclear reactor operation for example, a recent PSA estimation of this contribution is about 25% of the risk of core melting, all situations considered. This urges the designers of future nuclear reactors to consider the minimisation of this Human Factor (HF) contribution, at the very early stage of their design : the experience feedback shows that this is indeed at this stage that the fundamental design options, impacting the most the human reliability in operation, are fixed. The problem is that at these early design stages, it is also quite impossible to apply formal human reliability methods to support this HF optimisation, while the precise operating conditions of the reactor are not yet known in enough details. In this paper, another approach of the HF evaluation during the design, based on the functional and operational complexity assessment, is proposed. As an illustration, this approach is used to compare various concepts of Pressurized Water Reactors from the point of view of the Human Factor relevance. (Author)

  11. Chirality as a tool in nucleic acid recognition: principles and relevance in biotechnology and in medicinal chemistry.

    Science.gov (United States)

    Corradini, Roberto; Sforza, Stefano; Tedeschi, Tullia; Marchelli, Rosangela

    2007-05-05

    The understanding of the interaction of chiral species with DNA or RNA is very important for the development of new tools in biology and of new drugs. Several cases in which chirality is a crucial point in determining the DNA binding mode are reviewed and discussed, with the aim of illustrating how chirality can be considered as a tool for improving the understanding of mechanisms and the effectiveness of nucleic acid recognition. The review is divided into two parts: the former describes examples of chiral species interacting with DNA: intercalators, metal complexes, and groove binders; the latter part is dedicated to chirality in DNA analogs, with discussion of phosphate stereochemistry and chirality of ribose substitutes, in particular of peptide nucleic acids (PNAs) for which a number of works have been published recently dealing with the effect of chirality in DNA recognition. The discussion is intended to show how enantiomeric recognition originates at the molecular level, by exploiting the enormous progresses recently achieved in the field of structural characterization of complexes formed by nucleic acid with their ligands by crystallographic and spectroscopic methods. Examples of application of the DNA binding molecules described and the role of chirality in DNA recognition relevant for biotechnology or medicinal chemistry are reported. (c) 2007 Wiley-Liss, Inc.

  12. An analysis of physician antitrust exemption legislation: adjusting the balance of power.

    Science.gov (United States)

    Hellinger, F J; Young, G J

    2001-07-04

    Current antitrust law restricts physicians from joining together to collectively negotiate. However, such activities may be approved by state laws under the so-called state action immunity doctrine and by federal legislation under an explicit antitrust exemption. In 1999, Texas became the first state to pass physician antitrust exemption legislation allowing physicians, under certain defined circumstances, to collectively negotiate fees with health plans. Last year, similar legislation was introduced in the US Congress, in 18 state legislatures, and in the District of Columbia. This legislation was passed only in the District of Columbia where its implementation was blocked by the city's financial control board. Nonetheless, legislation permitting physicians to collectively negotiate fees with managed care plans has been introduced in 10 state legislatures this year, and there is continued interest in introducing similar legislation in the US Congress. This analysis examines the basic features of this legislation and its potential impact on the balance of power between physicians and managed care plans.

  13. Antitrust implications of utility participation in the market for remote photovoltaic systems

    International Nuclear Information System (INIS)

    Starrs, T.J.

    1994-01-01

    Remote photovoltaic systems are an important niche market in the development of a viable photovoltaics industry. Electric utilities in the US have started offering remote photovoltaic service. Utilities have the potential to use their monopoly power in regulated markets to unfair competitive advantage in competitive markets. Therefore, utility participation in remote photovoltaic markets raises potentially significant issues of antitrust law and policy. This paper describes some of the legal and factual criteria that US courts and regulatory agencies are likely to use in assessing the antitrust implications of utility participation in the market for remote photovoltaic systems

    To determine and compare the relevance of Piaget's cognitive principles among 4- to 7-year-old parented and orphan children in Belagavi City, Karnataka, India. This study was conducted on 240 children between the ages of 4 to 7 years who were equally divided into two groups of 120 parented and 120 orphan children. These were subdivided into four groups of 30 children each. Various characteristics like egocentrism, concept of cardinal numbers based on centration, lack of conservation, and reversibility were assessed, using experiments and comparison of their prevalence between two groups was carried out. There is a statistically significant difference in the cognitive development among parented and orphan children age 4 to 7 years. There is a significantly better cognitive development among parented children as compared with orphan children in Belagavi city. A child is not a miniature adult but rather can think and perceive the world differently from an adult. Understanding a child's intellectual level can enable a pedodontist to deliver improved quality care to children. According to Jean Piaget, in the preoperational period, children think symbolically and their reasoning is based more on appearance rather than logic. It is often rightly said that a child's behavior is a reflection of his parents. However, Piaget did not consider the effect of social setting and culture on the cognitive development. This study was carried out as there is not much literature available to describe the cognitive development of children in the Indian scenario and the influence of parental presence on the same.

  2. The roles of antitrust law and regulatory oversight in the restructured electricity industry

    Energy Technology Data Exchange (ETDEWEB)

    Glazer, C.A.; Little, M.B.

    1999-05-01

    The introduction of retail wheeling is changing the roles of regulators and the courts. When states unbundle the vertically integrated investor-owned utility (IOU) into generation companies, transmission companies, and distribution companies, antitrust enforcement and policy setting by the state public utility/service commissions (PUCs) will be paramount. As was seen in the deregulation of the airline industry, vigorous enforcement of antitrust laws by the courts and proper policy setting by the regulators are the keys to a successful competitive market. Many of the problems raised in the airline deregulation movement came about due to laxity in correcting clear antitrust violations and anti-competitive conditions before they caused damage to the market. As retail wheeling rolls out, it is critical for state PUCs to become attuned to these issues and, most of all, to have staff trained in these disciplines. The advent of retail wheeling changes the application of the State Action Doctrine and, in turn, may dramatically alter the role of the state PUC--meaning antitrust law and regulatory oversight must step in to protect competitors and consumers from monopolistic abuse.

  3. The U.S. Nuclear Regulatory Commission's antitrust review of nuclear power plants: the conditioning of licenses

    International Nuclear Information System (INIS)

    Penn, D.W.; Delaney, J.B.; Honeycutt, T.C.

    1976-04-01

    The 1970 amendments to Section 105 of the Atomic Energy Act require the Nuclear Regulatory Commission to conduct a prelicensing antitrust review of applications for licenses to construct and operate nuclear power plants. The Commission must make a finding as to whether the granting of a license 'would create or maintain a situation inconsistent with the antitrust laws,' and it has the authority to issue or continue a license, to refuse to issue a license, to rescind or amend a license, and to issue a license with conditions that it deems appropriate. This report provides information about the antitrust license conditions that have resulted from the NRC's antitrust review process. The process itself is described and a catalog of the applications requiring antitrust license conditions is presented. For each application, the license conditions are put into the general categories of unit access, transmission services, coordination, and contractual provisions. For completeness, the report also catalogs applications requiring no antitrust license conditions, and lists applications that were exempted from the 1970 amendments, are the subject of litigation, or have been withdrawn

  9. ECONOMIC AND LEGAL ASPECTS OF THE PLANNED DAMAGES ACTIONS FOR THE BREACHES OF EC ANTITRUST LAW

    Directory of Open Access Journals (Sweden)

    Elena Isac

    2010-09-01

    Full Text Available This paper investigates the planned damages actions for breaches of EC antitrust law in order to assess their impact on consumer welfare. It first examines the current legal situation and concurs that the European Union needs to regulate damages actions for breaches of EC antitrust law so that a higher number of consumers could be compensated for their losses. This paper then discusses the main legal provisions proposed by the Commission in the Green and in the White paper on damages actions for breaches of EC antitrust law. The analysis of these proposed legal provisions is done using arguments specific to the economic analysis of law. It is demonstrated that most of these proposed legal provisions will enhance consumer welfare but that there are also proposed legal provisions which will damage consumer welfare. The paper concludes that the planned damages actions for breaches of the EC law will be an improvement compared to the current situation. However, the Commission should amend some of the proposed legal provisions in order to help consumers further.

  10. Analysis of antitrust activity in the coal industry: 1964--1974

    Energy Technology Data Exchange (ETDEWEB)

    Hinson, W.R.

    1974-01-01

    During this period antitrust activity by the government in the coal industry was of a token nature and did not prevent (1) large investments in coal and uranium by large oil companies, nor (2) concentration with industry by large companies buying out small companies. A major result was the buying up of coal reserves, which were thus unavailable to small companies and hindered them from competing. Neither the government nor public utility companies did much to deter these developments and the results of the few court suits that were brought were not effective in discouraging the process. In fact, the widespread acceptance of nolo contendere pleas by the judicial system could make it profitable for a coal company to violate the antitrust laws. Several recommendations are made: (1) for more vigorous antitrust activity (with nonacceptance of nolo contendere pleas); (2) nationalisation of coal reserves (with bidding for reserves to be mined by competing companies); (3) a reporting system for ownership of coal reserves; and (4) encouragement of electric utilities to file private suit when anticompetitive behavior is suspected.

    Byrd, Gary D; Winkelstein, Peter

    2014-10-01

    Based on the authors' shared interest in the interprofessional challenges surrounding health information management, this study explores the degree to which librarians, informatics professionals, and core health professionals in medicine, nursing, and public health share common ethical behavior norms grounded in moral principles. Using the "Principlism" framework from a widely cited textbook of biomedical ethics, the authors analyze the statements in the ethical codes for associations of librarians (Medical Library Association [MLA], American Library Association, and Special Libraries Association), informatics professionals (American Medical Informatics Association [AMIA] and American Health Information Management Association), and core health professionals (American Medical Association, American Nurses Association, and American Public Health Association). This analysis focuses on whether and how the statements in these eight codes specify core moral norms (Autonomy, Beneficence, Non-Maleficence, and Justice), core behavioral norms (Veracity, Privacy, Confidentiality, and Fidelity), and other norms that are empirically derived from the code statements. These eight ethical codes share a large number of common behavioral norms based most frequently on the principle of Beneficence, then on Autonomy and Justice, but rarely on Non-Maleficence. The MLA and AMIA codes share the largest number of common behavioral norms, and these two associations also share many norms with the other six associations. The shared core of behavioral norms among these professions, all grounded in core moral principles, point to many opportunities for building effective interprofessional communication and collaboration regarding the development, management, and use of health information resources and technologies.

  12. Recent developments in national antitrust practice and case law: January 2012 – May 2013

    Directory of Open Access Journals (Sweden)

    Mario Siragusa

    2014-03-01

    Full Text Available In the period under review, the Italian Competition Authority and administrative courts analyzed many important cases in different economic sectors. Some of the these cases raised extremely complex legal and economic issues. The analysis of decision practice and case law highlights some critical aspects of recent antitrust enforcement, namely: (i the need to strengthen the fight against cartels; (ii the need to refine the tools used in merger analysis, also through the use of modern econometric methods; (iii the need to enhance the role of economic analysis in the assessment of unilateral exclusionary conduct, in line with the Commission’s Guidance on Article 102 TFEU; and (iv the need to find a better balance between competition rules and sector-specific regulation, so as to avoid overlapping and inconsistencies. A further critical issue is the need to reinforce the protection of the rights of defense. In order to improve the current administrative enforcement system, it is necessary to enhance the procedural guarantees and to remove the limits on judicial review of antitrust decisions, thus enabling administrative courts to review fully, in fact and in law, any aspect of the ICA’s finding of infringement, and to pronounce also on the merits of the case.

  13. Beyond Antitrust: Health Care And Health Insurance Market Trends And The Future Of Competition.

    Science.gov (United States)

    Glied, Sherry A; Altman, Stuart H

    2017-09-01

    The United States relies on competition to balance costs and quality in the health care system. But concentration is increasing throughout the hospital, physician, and insurer markets. Midsize community hospitals face declining demand and growing competition from both larger hospitals and smaller freestanding diagnostic and surgical centers, leaving the midsize hospitals vulnerable to closure or merger with other facilities. Competition among insurers has been limited by the development of hospital systems that extend the bargaining power of "must-have" hospitals (those perceived to provide the best care for complex and less common conditions) across local health care markets. Government antitrust enforcement could play an important role in maintaining competition in both the hospital and insurer markets, but in many markets, the impact of that enforcement has been limited to date. Policy makers should consider supplementing antitrust activities with strategies that combine competition and regulation-for example, by regulating selected prices and structuring competition to cover entire insurance markets.

  14. Impact of the antitrust laws on the commercialization of solar heating and cooling

    Energy Technology Data Exchange (ETDEWEB)

    Gross, J.

    1979-06-01

    Many energy industry observers and solar equipment producers view the commercialization of solar technologies as an opportunity to undermine the dominance now enjoyed by energy companies and electric utilities. Whether their hopes will be realized depends on Congress' posture towards interenergy diversification (which is currently permissive), DOE's spending practices (which have, in the past, been relatively insensitive to competitive consequences), and ultimately, the Supreme Court's willingness to aggressively enforce the antitrust laws (which is not unlikely, given recent holdings). Notwithstanding the legislative and administrative branches' tacit compliance with entrenched firms' involvement in the various solar energy submarkets, injured business persons and consumers (as well as the Department of Justice and the Federal Trade Commission) have the opportunity to force the controversy onto the judiciary by bringing suit under the antitrust laws against companies allegedly displaying anti-competitive market practices. The interchangeability between end uses of renewable and nonrenewable energy resources creates opportunities and motives for market manipulation. Consequently, the potential of energy firms for facilitating solar technology development (due to technological knowledge, managerial expertise and capital resources) must be weighed against the possibility that their involvement will, in the long run, retard development. 356 references.

    Full Text Available In the context of globalisation and EU member states’ efforts to overcome the difficulties of the economic crisis, realising the full potential of the Single Market is the main component of a credible plan for higher and sustainable growth in the EU. Competition policy is the central pillar of the Single Market. A strong antitrust enforcement, especially fighting cartels and preventing the creation of new ones, is at the core of open and fair pan-European markets, higher productivity and growth across Europe. This article summarizes the activities of the European Commission for the investigation and sanctioning of companies involved in cartels, focusing on the effectiveness of preventive policy of the Commission in antitrust enforcement, reflected in particular by the evolution of the fines imposed in cartel cases. The analysis outlines how antitrust policy contributes to strengthening the single market and the EU economic growth and examines the challenges for the implementation of antitrust policy caused by the changes in the dynamics and complexity of the economic environment, at the national and international level.

    Full Text Available Microsoft’s case has led to heated debates, both in Europe and the United States of America, on the abuse of the dominant position and on the prohibition of tying. This discussion, both in Europe and the United States, is not finished. In this article the author presents legal implications of tying products in Europe and Poland and confronts them with the American approach to tying. In Poland, a country with a fast developing economy, with the growing level of foreign investments, discussion on monopolist practices under the conditions of a fast technological development1 has not really commenced yet. The problems of innovation and development of New Economy undertakings has gained new impetus following Poland’s accession to the European Union. It is a matter of time when the anti-trust law begins to show interest in them. There are some indications that this has already taken place. In the first part of this article the author briefly presents the discussion related to Microsoft III case in the United States insofar as it pertains to New Economy issues. The second and third parts address legal and political aspects of the Microsoft case in the European Union. In the fourth part legal aspects related to tying practices in Poland are presented. The article aims to show that instrumental and mechanical treatment of tying practices used by firms having the market power under conditions of technological progress is not proper. The problem of antitrust analysis of such practices is universal, as universal as these practices are. However, the problem is solved differently in the United States and in Europe and the reasons for such a different approach are rooted in the legal system and policy enforcement. Microsoft antitrust is global. After US and European cases, Korean competition authority has found Microsoft guilty of tying practices2. Regarding Microsoft problems with tying it is necessary to ask the question whether tying practices are

    From time to time, groups of physicians in an area may determine that they would benefit from "integrating" their practices into an IPA, PHO, or other joint venture. The anticipated benefits may include economies of scale, the ability to coordinate care between primary care physicians and specialists, providing disease management services for patients with certain conditions, or a myriad of other reasons. A key characteristic of these proposed integrated models is the ability for the group as a whole to negotiate with insurance companies and self-funded health care plans. When a group reaches the point of negotiating collectively for the fees that a pay- or is going to pay for various services throughout the plan, possible antitrust implications arise.

  1. Health Care Efficiencies: Consolidation and Alternative Models vs. Health Care and Antitrust Regulation - Irreconcilable Differences?

    Science.gov (United States)

    King, Michael W

    2017-11-01

    Despite the U.S. substantially outspending peer high income nations with almost 18% of GDP dedicated to health care, on any number of statistical measurements from life expectancy to birth rates to chronic disease, 1 the U.S. achieves inferior health outcomes. In short, Americans receive a very disappointing return on investment on their health care dollars, causing economic and social strain. 2 Accordingly, the debates rage on: what is the top driver of health care spending? Among the culprits: poor communication and coordination among disparate providers, paperwork required by payors and regulations, well-intentioned physicians overprescribing treatments, drugs and devices, outright fraud and abuse, and medical malpractice litigation. Fundamentally, what is the best way to reduce U.S. health care spending, while improving the patient experience of care in terms of quality and satisfaction, and driving better patient health outcomes? Mergers, partnerships, and consolidation in the health care industry, new care delivery models like Accountable Care Organizations and integrated care systems, bundled payments, information technology, innovation through new drugs and new medical devices, or some combination of the foregoing? More importantly, recent ambitious reform efforts fall short of a cohesive approach, leaving fundamental internal inconsistencies across divergent arms of the federal government, raising the issue of whether the U.S. health care system can drive sufficient efficiencies within the current health care and antitrust regulatory environments. While debate rages on Capitol Hill over "repeal and replace," only limited attention has been directed toward reforming the current "fee-for-service" model pursuant to which providers are paid for volume of care rather than quality or outcomes. Indeed, both the Patient Protection and Affordable Care Act ("ACA") 3 and proposals for its replacement focus primarily on the reach and cost of providing coverage for

    Gustavo Ghidini

    2015-10-01

    Full Text Available Recent decisions of the European Court of Justice (Astrazeneca and Italian Antitrust Authority (Pfizer suggest that even the mere acquisition – as distinguished from the exercise – of a patent (as any other IPR may amount to a misuse if the achievement thereof runs in contrast with the rules governing its entitlement; and, if the patent owner enjoys a dominant position, such patent misuse may translate into an abuse of said position under art. 102 TFEU. Cases of this type must be clearly distinguished from those where the patent has been legitimately/regularly obtained, and its holder exercises the ‘institutionally excluding’ related power against unauthorized third parties. In such cases, antitrust law comes in not to enforce a properly ‘abusive’ conduct, but to correct an objective market situation which has grown ‘excessively’ foreclosing competition – and this, thanks to the very success of the patent. A situation, and a legal solution, which bears a strong analogy of rationale with the one envisaged by art. 2597 of Italian civil code. Thus, that of ‘abuse’ is a general normative tool that is used both to adjudicate anti-competitive torts (as in the first case and to regulate an objective ‘close to monopoly’ situation occurred without any wrongdoing by the patent holder.The distinction is confirmed by the consequences. On one side, as in Astrazeneca and Pfizer, the patent holders are sanctioned (and their patent or CCP is subject to annulment; no compensation whatever of the patentee is thinkable. On the other side, in the case of the regular acquisition and intrinsically legitimate exercise of the IPR competition law imposes a duty to license it on FRAND terms: i.e., with compensation of the patent holder, fully retains his entitlement. Here, self-evidently, the patent holder has behaved lawfully -otherwise a compensation would be unthinkable! The ‘abuse’ may properly occur ex post, i.e. only if the holder

    2009-01-01

    The purpose of this study is to define regulatory intervention as a part of a global monitoring procedure allowing the definition and adaptation of market structures and rules, given the observed behavior of market participants. Nevertheless, the possible inefficiency in its (decisional) coordination with competition authorities implies further analysis. We thus adopt a comparative methodology based on the studying PJM and NETA wholesale markets. This analysis enables us to stress two possible 'models' in the distribution and coordination of monitoring powers. The first one privileges a strong 'informational coordination' between the sectoral regulator and the Transmission System Operator. By contrast, the second model is characterized by a constrained informational coordination, leading to a greater 'decisional convergence' between regulatory intervention and antitrust policy. Lastly, we put these conclusions into perspective with the specific issue of the achievement of an efficient and integrated European market for electricity. In particular, we stress the need for a single regulatory agency, which should be given autonomous decisional powers in the adoption of regional markets reform initiatives (author)

    Access of third parties to power transmission systems which up to now is governed in Germany by ownership rights will not run smoothly in future, although the general policy decision ended the dispute about the if, however leaving open aspects of the how. The problems arising in designing the how are currently displayed to the public by the disputes about conditions and model solutions reported from the telecommunications area, where deregulation is ahead of the developments in the energy sector. Obviously, the contention point is not technical feasibility of third party access, but the economic aspects and the conditions offered to competing suppliers depending on access to a transmission network. Hence it can be expected that there will be conflicts of interest that will have to be decided. The legal basis for conflict management is outlined in the recent amendment to the EnWG (German energy industry act), and jurisdiction will primarily rely on paragraph 6 of the act, referring to antitrust review. The contribution here gives an outline of the legal framework conditions governing enforcement of third party access to transmission systems in the future deregulated energy market.

As firmas capitalistas convencionais objetivam a maximização dos lucros, enquanto que as firmas cooperadas objetivam a estabilidade do emprego e do produto. A política antitruste tem replicado o mesmo tratamento despendido às firmas capitalistas convencionais para os casos envolvendo as firmas cooperadas. Tal decisão pode aumentar a probabilidade de ocorrências de erros do tipo I e do tipo II. Esse problema se torna menor quando os casos envolvem "falsas cooperativas". Em termos de política pública, a conclusão do presente artigo é de que uma concentração ou coordenação entre cooperados de fato ou profissionais não é, per se, condição necessária e suficiente para causar dano concorrencial. As especificidades destes tipos de organizações demandam análise específica e a aplicação da regra da razão. Finalmente, o artigo fornece uma proposta de filtro para distinção entre firmas cooperadas de fato e de cartéis disfarçados de cooperativas.

    Directory of Open Access Journals (Sweden)

    César Mattos

    2012-06-01

    Full Text Available In 2010, the Brazilian Antitrust Authority -CADE- concluded an agreeement with Globo and the "Club of 13" on a three-year deal for the exclusive broadcasting rights to all Brazilian Football League (BFL games spanning the five principal media platforms: free-to-air TV, pay TV, Pay per View, Internet and Mobile. The deal eliminates competition in broadcasting of Brazilian League games (primarily other networks, including Record, SBT, ESPN, etc., reducing "competition in the market." However, it is plausible to assume that exclusivity can bring efficiencies to the market by ensuring a return on investments. In addition, the sale of broadcasting rights accounts for nearly 40% of the revenues of Brazilian clubs. Banning exclusivity will likely reduce revenues and dampen sector efficiency. However, the contract included a preference clause for Globo that adversely affected "competition for the market." Globo abandoned the preference clause under the agreement. Another important provision of the agreement was the requirement that the Club of 13 auction the five media platforms separately. This article examines the economic rationale of the agreement and provides a brief analysis of the main lessons arising from the fragmentation of negotiations in 2011.

    The Cosmological Principle states: the universe looks the same to all observers regardless of where they are located. To most astronomers today the Cosmological Principle means the universe looks the same to all observers because density of the galaxies is the same in all places. A new Cosmological Principle is proposed. It is called the Dimensional Cosmological Principle. It uses the properties of matter in the universe: density (rho), pressure (p), and mass (m) within some region of space of length (l). The laws of physics require incorporation of constants for gravity (G) and the speed of light (C). After combining the six parameters into dimensionless numbers, the best choices are: 8πGl 2 rho/c 2 , 8πGl 2 rho/c 4 , and 2 Gm/c 2 l (the Schwarzchild factor). The Dimensional Cosmological Principal came about because old ideas conflicted with the rapidly-growing body of observational evidence indicating that galaxies in the universe have a clumpy rather than uniform distribution

An important aspect of the fuel cycle concerns the possibility of ''closing the back end'' i.e. reprocessing the waste or unused fuel in order to re-use it in reactors of various kinds. The alternative, the ''oncethrough'' cycle, discards the discharged fuel completely. An interim measure involves the prolonged storage of highly radioactive waste fuel. (UK)

Dentre os sete princípios por ela recomendados para a América Latina, este trabalho tem como foco apenas o quinto princípio, que trata das "Responsabilidades do Conselho de Administração", mais especificadamente das recomendações com respeito à "Integridade dos Conselhos e Autonomia dos Conselheiros". O principal objetivo é de verificar o posicionamento das empresas em relação às responsabilidades e a supervisão dos administradores como forma de garantir o controle e os resultados esperados pelos acionistas. Para atingir esse objetivo, formulou-se um questionário que expressa as principais recomendações de governança da OCDE para a América Latina e confrontou-se com as legislações desses quatro países e com as práticas societárias das empresas da amostra, de modo a identificar procedimentos adicionais em relação aos exigidos pela legislação. Os resultados evidenciam que o México é o país com maior índice de atendimento às recomendações da OCDE, seguido do Brasil, Argentina e Chile. Os principais pontos fracos, de modo geral, são a ausência de comitês específicos, compostos, no mínimo, por maioria de conselheiros independentes, e proibições de práticas como reuniões prévias ou instruções de voto dadas por acionistas controladores a conselheiros.Boards of directors are characterized as important elements for good corporate governance.

    One of the common features in all promising candidates of quantum gravity is the existence of a minimal length scale, which naturally emerges with a generalized uncertainty principle, or equivalently a modified commutation relation. Schwinger's quantum action principle was modified to incorporate this modification, and was applied to the calculation of the kernel of a free particle, partly recovering the result previously studied using path integral.

    The dimensional cosmological principles proposed by Wesson require that the density, pressure, and mass of cosmological models be functions of the dimensionless variables which are themselves combinations of the gravitational constant, the speed of light, and the spacetime coordinates. The space coordinate is not the comoving coordinate. In this paper, the dimensional cosmological principle and the dimensional perfect cosmological principle are reformulated by using the comoving coordinate. The dimensional perfect cosmological principle is further modified to allow the possibility that mass creation may occur. Self-similar spacetimes are found to be models obeying the new dimensional cosmological principle

  9. The principle of proportionality revisited: interpretations and applications.

    Science.gov (United States)

    Hermerén, Göran

    2012-11-01

    The principle of proportionality is used in many different contexts. Some of these uses and contexts are first briefly indicated. This paper focusses on the use of this principle as a moral principle. I argue that under certain conditions the principle of proportionality is helpful as a guide in decision-making. But it needs to be clarified and to be used with some flexibility as a context-dependent principle. Several interpretations of the principle are distinguished, using three conditions as a starting point: importance of objective, relevance of means, and most favourable option. The principle is then tested against an example, which suggests that a fourth condition, focusing on non-excessiveness, needs to be added. I will distinguish between three main interpretations of the principle, some primarily with uses in research ethics, others with uses in other areas of bioethics, for instance in comparisons of therapeutic means and ends. The relations between the principle of proportionality and the precautionary principle are explored in the following section. It is concluded that the principles are different and may even clash. In the next section the principle of proportionality is applied to some medical examples drawn from research ethics and bioethics. In concluding, the status of the principle of proportionality as a moral principle is discussed. What has been achieved so far and what remains to be done is finally summarized.

  11. A cyclic symmetry principle in physics

    International Nuclear Information System (INIS)

    Green, H.S.; Adelaide Univ., SA

    1994-01-01

    Many areas of modern physics are illuminated by the application of a symmetry principle, requiring the invariance of the relevant laws of physics under a group of transformations. This paper examines the implications and some of the applications of the principle of cyclic symmetry, especially in the areas of statistical mechanics and quantum mechanics, including quantized field theory. This principle requires invariance under the transformations of a finite group, which may be a Sylow π-group, a group of Lie type, or a symmetric group. The utility of the principle of cyclic invariance is demonstrated in finding solutions of the Yang-Baxter equation that include and generalize known solutions. It is shown that the Sylow π-groups have other uses, in providing a basis for a type of generalized quantum statistics, and in parametrising a new generalization of Lie groups, with associated algebras that include quantized algebras. 31 refs

  14. PRINCIPLES AND PROCEDURES ON FISCAL

    Directory of Open Access Journals (Sweden)

    Morar Ioan Dan

    2011-07-01

    Full Text Available Fiscal science advertise in most analytical situations, while the principles reiterated by specialists in the field in various specialized works The two components of taxation, the tax system relating to the theoretical and the practical procedures relating to tax are marked by frequent references and invocations of the underlying principles to tax. This paper attempts a return on equity fiscal general vision as a principle often invoked and used to justify tax policies, but so often violated the laws fiscality . Also want to emphasize the importance of devising procedures to ensure fiscal equitable treatment of taxpayers. Specific approach of this paper is based on the notion that tax equity is based on equality before tax and social policies of the executive that would be more effective than using the other tax instruments. I want to emphasize that if the scientific approach to justify the unequal treatment of the tax law is based on the various social problems of the taxpayers, then deviates from the issue of tax fairness justification explaining the need to promote social policies usually more attractive to taxpayers. Modern tax techniques are believed to be promoted especially in order to ensure an increasing level of high efficiency at the expense of the taxpayers obligations to ensure equality before the law tax. On the other hand, tax inequities reaction generates multiple recipients from the first budget plan, but finalities unfair measures can not quantify and no timeline for the reaction, usually not known. But while statistics show fluctuations in budgetary revenues and often find in literature reviews and analysis relevant to a connection between changes in government policies, budget execution and outcome. The effects of inequality on tax on tax procedures and budgetary revenues are difficult to quantify and is among others to this work. Providing tax equity without combining it with the principles of discrimination and neutrality

  15. The genetic difference principle.

    Science.gov (United States)

    Farrelly, Colin

    2004-01-01

    In the newly emerging debates about genetics and justice three distinct principles have begun to emerge concerning what the distributive aim of genetic interventions should be. These principles are: genetic equality, a genetic decent minimum, and the genetic difference principle. In this paper, I examine the rationale of each of these principles and argue that genetic equality and a genetic decent minimum are ill-equipped to tackle what I call the currency problem and the problem of weight. The genetic difference principle is the most promising of the three principles and I develop this principle so that it takes seriously the concerns of just health care and distributive justice in general. Given the strains on public funds for other important social programmes, the costs of pursuing genetic interventions and the nature of genetic interventions, I conclude that a more lax interpretation of the genetic difference principle is appropriate. This interpretation stipulates that genetic inequalities should be arranged so that they are to the greatest reasonable benefit of the least advantaged. Such a proposal is consistent with prioritarianism and provides some practical guidance for non-ideal societies--that is, societies that do not have the endless amount of resources needed to satisfy every requirement of justice.

    A premium principle is derived, in which the loading for a risk is the reinsurance loading for an excess-of-loss cover. It is shown that the principle is well-behaved in the sense that it results in larger premiums for risks that are larger in stop-loss order or in stochastic dominance.

  20. Mach's holographic principle

    International Nuclear Information System (INIS)

    Khoury, Justin; Parikh, Maulik

    2009-01-01

    Mach's principle is the proposition that inertial frames are determined by matter. We put forth and implement a precise correspondence between matter and geometry that realizes Mach's principle. Einstein's equations are not modified and no selection principle is applied to their solutions; Mach's principle is realized wholly within Einstein's general theory of relativity. The key insight is the observation that, in addition to bulk matter, one can also add boundary matter. Given a space-time, and thus the inertial frames, we can read off both boundary and bulk stress tensors, thereby relating matter and geometry. We consider some global conditions that are necessary for the space-time to be reconstructible, in principle, from bulk and boundary matter. Our framework is similar to that of the black hole membrane paradigm and, in asymptotically anti-de Sitter space-times, is consistent with holographic duality.

  1. Variational principles in physics

    CERN Document Server

    Basdevant, Jean-Louis

    2007-01-01

    Optimization under constraints is an essential part of everyday life. Indeed, we routinely solve problems by striking a balance between contradictory interests, individual desires and material contingencies. This notion of equilibrium was dear to thinkers of the enlightenment, as illustrated by Montesquieu’s famous formulation: "In all magistracies, the greatness of the power must be compensated by the brevity of the duration." Astonishingly, natural laws are guided by a similar principle. Variational principles have proven to be surprisingly fertile. For example, Fermat used variational methods to demonstrate that light follows the fastest route from one point to another, an idea which came to be known as Fermat’s principle, a cornerstone of geometrical optics. Variational Principles in Physics explains variational principles and charts their use throughout modern physics. The heart of the book is devoted to the analytical mechanics of Lagrange and Hamilton, the basic tools of any physicist. Prof. Basdev...

  2. The Limits to Relevance

    Science.gov (United States)

    Averill, M.; Briggle, A.

    2006-12-01

    Science policy and knowledge production lately have taken a pragmatic turn. Funding agencies increasingly are requiring scientists to explain the relevance of their work to society. This stems in part from mounting critiques of the "linear model" of knowledge production in which scientists operating according to their own interests or disciplinary standards are presumed to automatically produce knowledge that is of relevance outside of their narrow communities. Many contend that funded scientific research should be linked more directly to societal goals, which implies a shift in the kind of research that will be funded. While both authors support the concept of useful science, we question the exact meaning of "relevance" and the wisdom of allowing it to control research agendas. We hope to contribute to the conversation by thinking more critically about the meaning and limits of the term "relevance" and the trade-offs implicit in a narrow utilitarian approach. The paper will consider which interests tend to be privileged by an emphasis on relevance and address issues such as whose goals ought to be pursued and why, and who gets to decide. We will consider how relevance, narrowly construed, may actually limit the ultimate utility of scientific research. The paper also will reflect on the worthiness of research goals themselves and their relationship to a broader view of what it means to be human and to live in society. Just as there is more to being human than the pragmatic demands of daily life, there is more at issue with knowledge production than finding the most efficient ways to satisfy consumer preferences or fix near-term policy problems. We will conclude by calling for a balanced approach to funding research that addresses society's most pressing needs but also supports innovative research with less immediately apparent application.

  3. Relevant Subspace Clustering

    DEFF Research Database (Denmark)

    Müller, Emmanuel; Assent, Ira; Günnemann, Stephan

    2009-01-01

    Subspace clustering aims at detecting clusters in any subspace projection of a high dimensional space. As the number of possible subspace projections is exponential in the number of dimensions, the result is often tremendously large. Recent approaches fail to reduce results to relevant subspace...... clusters. Their results are typically highly redundant, i.e. many clusters are detected multiple times in several projections. In this work, we propose a novel model for relevant subspace clustering (RESCU). We present a global optimization which detects the most interesting non-redundant subspace clusters...... achieves top clustering quality while competing approaches show greatly varying performance....

  4. Limitations of Boltzmann's principle

    International Nuclear Information System (INIS)

    Lavenda, B.H.

    1995-01-01

    The usual form of Boltzmann's principle assures that maximum entropy, or entropy reduction, occurs with maximum probability, implying a unimodal distribution. Boltzmann's principle cannot be applied to nonunimodal distributions, like the arcsine law, because the entropy may be concave only over a limited portion of the interval. The method of subordination shows that the arcsine distribution corresponds to a process with a single degree of freedom, thereby confirming the invalidation of Boltzmann's principle. The fractalization of time leads to a new distribution in which arcsine and Cauchy distributions can coexist simultaneously for nonintegral degrees of freedom between √2 and 2

    Bioethics emerges about the tecnological problems of acting in human life. Emerges also the problem of the moral limits determination, because they seem exterior of this practice. The Bioethics of Principles, take his rationality of the teleological thinking, and the autonomism. These divergence manifest the epistemological fragility and the great difficulty of hmoralñ thinking. This is evident in the determination of autonomy's principle, it has not the ethical content of Kant's propose.

    I find that students have difficulty with Hamilton's principle, at least the first time they come into contact with it, and therefore it is worth designing some examples to help students grasp its complex meaning. This paper supplies the simplest example to consolidate the learning of the quoted principle: that of a free particle moving along a line. Next, students are challenged to add gravity to reinforce the argument and, finally, a two-dimensional motion in a vertical plane is considered. Furthermore these examples force us to be very clear about such an abstract principle

  13. On the invariance principle

    Energy Technology Data Exchange (ETDEWEB)

    Moller-Nielsen, Thomas [University of Oxford (United Kingdom)

    2014-07-01

    Physicists and philosophers have long claimed that the symmetries of our physical theories - roughly speaking, those transformations which map solutions of the theory into solutions - can provide us with genuine insight into what the world is really like. According to this 'Invariance Principle', only those quantities which are invariant under a theory's symmetries should be taken to be physically real, while those quantities which vary under its symmetries should not. Physicists and philosophers, however, are generally divided (or, indeed, silent) when it comes to explaining how such a principle is to be justified. In this paper, I spell out some of the problems inherent in other theorists' attempts to justify this principle, and sketch my own proposed general schema for explaining how - and when - the Invariance Principle can indeed be used as a legitimate tool of metaphysical inference.

    Science.gov (United States)

    Gordon, John-Stewart

    2011-09-01

    This article examines the special relation between common morality and particular moralities in the four-principles approach and its use for global ethics. It is argued that the special dialectical relation between common morality and particular moralities is the key to bridging the gap between ethical universalism and relativism. The four-principles approach is a good model for a global bioethics by virtue of its ability to mediate successfully between universal demands and cultural diversity. The principle of autonomy (i.e., the idea of individual informed consent), however, does need to be revised so as to make it compatible with alternatives such as family- or community-informed consent. The upshot is that the contribution of the four-principles approach to global ethics lies in the so-called dialectical process and its power to deal with cross-cultural issues against the background of universal demands by joining them together.

  1. Remark on Heisenberg's principle

    International Nuclear Information System (INIS)

    Noguez, G.

    1988-01-01

    Application of Heisenberg's principle to inertial frame transformations allows a distinction between three commutative groups of reciprocal transformations along one direction: Galilean transformations, dual transformations, and Lorentz transformations. These are three conjugate groups and for a given direction, the related commutators are all proportional to one single conjugation transformation which compensates for uniform and rectilinear motions. The three transformation groups correspond to three complementary ways of measuring space-time as a whole. Heisenberg's Principle then gets another explanation [fr

    To present insights to aid decision-making about novel veterinary treatments from regulations concerning animal experimentation and human clinical medical trials. EU Directive 2010/63/EU on the protection of animals used for scientific purposes and EU Regulation 536/2014 on clinical trials on medicinal products for human use were analysed, evaluated and "translated" into relevant principles for veterinary surgeons. A number of principles are relevant, relating to treatment expectations, thresholds and objectives; client consent; minimising harms; personnel; review committees; assessment and publication. These principles should assist veterinary surgeons to make good ethical decisions about novel treatments. © 2015 British Small Animal Veterinary Association.

  3. First principles of Hamiltonian medicine.

    Science.gov (United States)

    Crespi, Bernard; Foster, Kevin; Úbeda, Francisco

    2014-05-19

    We introduce the field of Hamiltonian medicine, which centres on the roles of genetic relatedness in human health and disease. Hamiltonian medicine represents the application of basic social-evolution theory, for interactions involving kinship, to core issues in medicine such as pathogens, cancer, optimal growth and mental illness. It encompasses three domains, which involve conflict and cooperation between: (i) microbes or cancer cells, within humans, (ii) genes expressed in humans, (iii) human individuals. A set of six core principles, based on these domains and their interfaces, serves to conceptually organize the field, and contextualize illustrative examples. The primary usefulness of Hamiltonian medicine is that, like Darwinian medicine more generally, it provides novel insights into what data will be productive to collect, to address important clinical and public health problems. Our synthesis of this nascent field is intended predominantly for evolutionary and behavioural biologists who aspire to address questions directly relevant to human health and disease.

  4. Indeterminacy and the principle of need.

    Science.gov (United States)

    Herlitz, Anders

    2017-02-01

    The principle of need-the idea that resources should be allocated according to need-is often invoked in priority setting in the health care sector. In this article, I argue that a reasonable principle of need must be indeterminate, and examine three different ways that this can be dealt with: appendicizing the principle with further principles, imposing determinacy, or empowering decision makers. I argue that need must be conceptualized as a composite property composed of at least two factors: health shortfall and capacity to benefit. When one examines how the different factors relate to each other, one discovers that this is sometimes indeterminate. I illustrate this indeterminacy in this article by applying the small improvement argument. If the relation between the factors are always determinate, the comparative relation changes by a small adjustment. Yet, if two needs are dissimilar but of seemingly equal magnitude, the comparative relation does not change by a small adjustment of one of the factors. I then outline arguments in favor of each of the three strategies for dealing with indeterminacy, but also point out that all strategies have significant shortcomings. More research is needed concerning how to deal with this indeterminacy, and the most promising path seems to be to scrutinize the position of the principle of need among a plurality of relevant principles for priority setting in the health care sector.

  5. Clinical Relevance of Adipokines

    2012-10-01

    Full Text Available The incidence of obesity has increased dramatically during recent decades. Obesity increases the risk for metabolic and cardiovascular diseases and may therefore contribute to premature death. With increasing fat mass, secretion of adipose tissue derived bioactive molecules (adipokines changes towards a pro-inflammatory, diabetogenic and atherogenic pattern. Adipokines are involved in the regulation of appetite and satiety, energy expenditure, activity, endothelial function, hemostasis, blood pressure, insulin sensitivity, energy metabolism in insulin sensitive tissues, adipogenesis, fat distribution and insulin secretion in pancreatic β-cells. Therefore, adipokines are clinically relevant as biomarkers for fat distribution, adipose tissue function, liver fat content, insulin sensitivity, chronic inflammation and have the potential for future pharmacological treatment strategies for obesity and its related diseases. This review focuses on the clinical relevance of selected adipokines as markers or predictors of obesity related diseases and as potential therapeutic tools or targets in metabolic and cardiovascular diseases.

  7. The nullum crimen sine iure principle in contemporary International Law

    Directory of Open Access Journals (Sweden)

    Hector Olásolo Alonso

    2014-03-01

    Full Text Available This paper deals with the evolution and current content of the nullum crimen sine iure principle in international law. It analyses the development of the nullum crimen principle from its definition as a principle of justice at the end of Second World War, to its current definition as an individual right imposing a limitation upon States’ sovereignty. The article also explains that, nowadays, the nullum cri- men principle requires for the relevant conduct to be a crime at the time of its com- mission, according to any of the sources of criminal law in the relevant national or international legal system. No written law is necessarily required. As a result, accessibility and foreseability are the main elements of the nullum crimen principle in current international law.

  8. A Principle of Intentionality.

    Science.gov (United States)

    Turner, Charles K

    2017-01-01

    The mainstream theories and models of the physical sciences, including neuroscience, are all consistent with the principle of causality. Wholly causal explanations make sense of how things go, but are inherently value-neutral, providing no objective basis for true beliefs being better than false beliefs, nor for it being better to intend wisely than foolishly. Dennett (1987) makes a related point in calling the brain a syntactic (procedure-based) engine. He says that you cannot get to a semantic (meaning-based) engine from there. He suggests that folk psychology revolves around an intentional stance that is independent of the causal theories of the brain, and accounts for constructs such as meanings, agency, true belief, and wise desire. Dennett proposes that the intentional stance is so powerful that it can be developed into a valid intentional theory. This article expands Dennett's model into a principle of intentionality that revolves around the construct of objective wisdom. This principle provides a structure that can account for all mental processes, and for the scientific understanding of objective value. It is suggested that science can develop a far more complete worldview with a combination of the principles of causality and intentionality than would be possible with scientific theories that are consistent with the principle of causality alone.

  9. General principles of radiotherapy

    Easson, E.C.

    1985-01-01

    The daily practice of any established branch of medicine should be based on some acceptable principles. This chapter is concerned with the general principles on which the radiotherapy of the Manchester school is based. Though many radiotherapists in other centres would doubtless accept these principles, there are sufficiently wide differences in practice throughout the world to suggest that some therapists adhere to a fundamentally different philosophy. The authors believe it is important, especially for those beginning their formal training in radiotherapy, to subscribe to an internally consistent school of thought, employing methods of treatment for each type of lesion in each anatomical site that are based on accepted principles and subjected to continuous rigorous scrutiny to test their effectiveness. Not only must each therapeutic technique be evaluated, but the underlying principles too must be questioned if and when this seems indicated. It is a feature of this hospital that similar lesions are all treated by the same technique, so long as statistical evidence justifies such a policy. All members of the staff adhere to the accepted policy until or unless reliable reasons are adduced to change this policy

  10. The traveltime holographic principle

    Science.gov (United States)

    Huang, Yunsong; Schuster, Gerard T.

    2015-01-01

    Fermat's interferometric principle is used to compute interior transmission traveltimes τpq from exterior transmission traveltimes τsp and τsq. Here, the exterior traveltimes are computed for sources s on a boundary B that encloses a volume V of interior points p and q. Once the exterior traveltimes are computed, no further ray tracing is needed to calculate the interior times τpq. Therefore this interferometric approach can be more efficient than explicitly computing interior traveltimes τpq by ray tracing. Moreover, the memory requirement of the traveltimes is reduced by one dimension, because the boundary B is of one fewer dimension than the volume V. An application of this approach is demonstrated with interbed multiple (IM) elimination. Here, the IMs in the observed data are predicted from the migration image and are subsequently removed by adaptive subtraction. This prediction is enabled by the knowledge of interior transmission traveltimes τpq computed according to Fermat's interferometric principle. We denote this principle as the `traveltime holographic principle', by analogy with the holographic principle in cosmology where information in a volume is encoded on the region's boundary.

    Science.gov (United States)

    Schultz, R C

    1993-01-01

    Ethical theory about what is right and good in human conduct lies behind the issues practitioners face and the codes they turn to for guidance; it also provides guidance for actions, practices, and policies. Principles of obligation, such as egoism, utilitarianism, and deontology, offer general answers to the question, "Which acts/practices are morally right?" A re-emerging alternative to using such principles to assess individual conduct is to center normative theory on personal virtues. For structuring society's institutions, principles of social justice offer alternative answers to the question, "How should social benefits and burdens be distributed?" But human concerns about right and good call for more than just theoretical responses. Some critics (eg, the postmodernists and the feminists) charge that normative ethical theorizing is a misguided enterprise. However, that charge should be taken as a caution and not as a refutation of normative ethical theorizing.

    Principles of Musical Acoustics focuses on the basic principles in the science and technology of music. Musical examples and specific musical instruments demonstrate the principles. The book begins with a study of vibrations and waves, in that order. These topics constitute the basic physical properties of sound, one of two pillars supporting the science of musical acoustics. The second pillar is the human element, the physiological and psychological aspects of acoustical science. The perceptual topics include loudness, pitch, tone color, and localization of sound. With these two pillars in place, it is possible to go in a variety of directions. The book treats in turn, the topics of room acoustics, audio both analog and digital, broadcasting, and speech. It ends with chapters on the traditional musical instruments, organized by family. The mathematical level of this book assumes that the reader is familiar with elementary algebra. Trigonometric functions, logarithms and powers also appear in the book, but co...

    2016-01-01

    Like pain, itch is a challenging condition that needs to be managed. Within this setting, the first principle of itch management is to get an appropriate diagnosis to perform an etiology-oriented therapy. In several cases it is not possible to treat the cause, the etiology is undetermined, there are several causes, or the etiological treatment is not effective enough to alleviate itch completely. This is also why there is need for symptomatic treatment. In all patients, psychological support and associated pragmatic measures might be helpful. General principles and guidelines are required, yet patient-centered individual care remains fundamental. © 2016 S. Karger AG, Basel.

    Diarrhea remains the third leading cause of death in children under five years, despite recent advances in the management and prevention of this disease. It is caused by multiple pathogens, however, the prevalence of each varies by age group, geographical area and the scenario where cases (community vs hospital) are recorded. The most relevant pathogens in public health are those associated with the highest burden of disease, severity, complications and mortality. In our country, norovirus, Campylobacter and diarrheagenic E. coli are the most prevalent pathogens at the community level in children. In this paper we review the local epidemiology and potential areas of development in five selected pathogens: rotavirus, norovirus, Shiga toxin-producing E. coli (STEC), Shigella and Salmonella. Of these, rotavirus is the most important in the pediatric population and the main agent responsible for child mortality from diarrhea. The introduction of rotavirus vaccination in Peru will have a significant impact on disease burden and mortality from diarrhea. However, surveillance studies are needed to determine the impact of vaccination and changes in the epidemiology of diarrhea in Peru following the introduction of new vaccines, as well as antibiotic resistance surveillance of clinical relevant bacteria.

    This work presents a summary of the IAEA Safety Standards Series publication No. SF-1 entitled F UDAMENTAL Safety PRINCIPLES p ublished on 2006. This publication states the fundamental safety objective and ten associated safety principles, and briefly describes their intent and purposes. Safety measures and security measures have in common the aim of protecting human life and health and the environment. These safety principles are: 1) Responsibility for safety, 2) Role of the government, 3) Leadership and management for safety, 4) Justification of facilities and activities, 5) Optimization of protection, 6) Limitation of risks to individuals, 7) Protection of present and future generations, 8) Prevention of accidents, 9)Emergency preparedness and response and 10) Protective action to reduce existing or unregulated radiation risks. The safety principles concern the security of facilities and activities to the extent that they apply to measures that contribute to both safety and security. Safety measures and security measures must be designed and implemented in an integrated manner so that security measures do not compromise safety and safety measures do not compromise security.

    Callréus, Torbjörn

    2005-01-01

    Although it is often vigorously contested and has several different formulations, the precautionary principle has in recent decades guided environmental policy making in the face of scientific uncertainty. Originating from a criticism of traditional risk assessment, the key element of the precautionary principle is the justification for acting in the face of uncertain knowledge about risks. In the light of its growing invocation in various areas that are related to public health and recently in relation to drug safety issues, this article presents an introductory review of the main elements of the precautionary principle and some arguments conveyed by its advocates and opponents. A comparison of the characteristics of pharmaceutical risk management and environmental policy making (i.e. the setting within which the precautionary principle evolved), indicates that several important differences exist. If believed to be of relevance, in order to avoid arbitrary and unpredictable decision making, both the interpretation and possible application of the precautionary principle need to be adapted to the conditions of pharmaceutical risk management.

Prigogine's principle of minimum rate of entropy production has a physical interpretation when it applies, but is not strictly valid except for a very special case

    2016-02-01

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

  3. Principles of geodynamics

    CERN Document Server

    Scheidegger, Adrian E

    1982-01-01

    Geodynamics is commonly thought to be one of the subjects which provide the basis for understanding the origin of the visible surface features of the Earth: the latter are usually assumed as having been built up by geodynamic forces originating inside the Earth ("endogenetic" processes) and then as having been degrad­ ed by geomorphological agents originating in the atmosphere and ocean ("exogenetic" agents). The modem view holds that the sequence of events is not as neat as it was once thought to be, and that, in effect, both geodynamic and geomorphological processes act simultaneously ("Principle of Antagonism"); however, the division of theoretical geology into the principles of geodynamics and those of theoretical geomorphology seems to be useful for didactic purposes. It has therefore been maintained in the present writer's works. This present treatise on geodynamics is the first part of the author's treatment of theoretical geology, the treatise on Theoretical Geomorphology (also published by the Sprin...

  4. Principles of systems science

    CERN Document Server

    Mobus, George E

    2015-01-01

    This pioneering text provides a comprehensive introduction to systems structure, function, and modeling as applied in all fields of science and engineering. Systems understanding is increasingly recognized as a key to a more holistic education and greater problem solving skills, and is also reflected in the trend toward interdisciplinary approaches to research on complex phenomena. The subject of systems science, as a basis for understanding the components and drivers of phenomena at all scales, should be viewed with the same importance as a traditional liberal arts education. Principles of Systems Science contains many graphs, illustrations, side bars, examples, and problems to enhance understanding. From basic principles of organization, complexity, abstract representations, and behavior (dynamics) to deeper aspects such as the relations between information, knowledge, computation, and system control, to higher order aspects such as auto-organization, emergence and evolution, the book provides an integrated...

    Judgment on rightness and wrongness of beliefs and behaviors is a main issue in bioethics. Over centuries, big philosophers and ethicists have been discussing the suitable tools to determine which act is morally sound and which one is not. Emerging the contemporary bioethics in the West has resulted in a misconception that absolute westernized principles would be appropriate tools for ethical decision making in different cultures. We will discuss this issue by introducing a clinical case. Considering various cultural beliefs around the world, though it is not logical to consider all of them ethically acceptable, we can gather on some general fundamental principles instead of going to the extremes of relativism and absolutism. Islamic teachings, according to the presented evidence in this paper, fall in with this idea.

    2004-01-01

    Science and engineering students depend heavily on concepts of mathematical modeling. In an age where almost everything is done on a computer, author Clive Dym believes that students need to understand and "own" the underlying mathematics that computers are doing on their behalf. His goal for Principles of Mathematical Modeling, Second Edition, is to engage the student reader in developing a foundational understanding of the subject that will serve them well into their careers. The first half of the book begins with a clearly defined set of modeling principles, and then introduces a set of foundational tools including dimensional analysis, scaling techniques, and approximation and validation techniques. The second half demonstrates the latest applications for these tools to a broad variety of subjects, including exponential growth and decay in fields ranging from biology to economics, traffic flow, free and forced vibration of mechanical and other systems, and optimization problems in biology, structures, an...

    Howell, Kenneth B

    2001-01-01

    Fourier analysis is one of the most useful and widely employed sets of tools for the engineer, the scientist, and the applied mathematician. As such, students and practitioners in these disciplines need a practical and mathematically solid introduction to its principles. They need straightforward verifications of its results and formulas, and they need clear indications of the limitations of those results and formulas.Principles of Fourier Analysis furnishes all this and more. It provides a comprehensive overview of the mathematical theory of Fourier analysis, including the development of Fourier series, "classical" Fourier transforms, generalized Fourier transforms and analysis, and the discrete theory. Much of the author''s development is strikingly different from typical presentations. His approach to defining the classical Fourier transform results in a much cleaner, more coherent theory that leads naturally to a starting point for the generalized theory. He also introduces a new generalized theory based ...

    Lang, Kyle M; Little, Todd D

    2018-04-01

    We review a number of issues regarding missing data treatments for intervention and prevention researchers. Many of the common missing data practices in prevention research are still, unfortunately, ill-advised (e.g., use of listwise and pairwise deletion, insufficient use of auxiliary variables). Our goal is to promote better practice in the handling of missing data. We review the current state of missing data methodology and recent missing data reporting in prevention research. We describe antiquated, ad hoc missing data treatments and discuss their limitations. We discuss two modern, principled missing data treatments: multiple imputation and full information maximum likelihood, and we offer practical tips on how to best employ these methods in prevention research. The principled missing data treatments that we discuss are couched in terms of how they improve causal and statistical inference in the prevention sciences. Our recommendations are firmly grounded in missing data theory and well-validated statistical principles for handling the missing data issues that are ubiquitous in biosocial and prevention research. We augment our broad survey of missing data analysis with references to more exhaustive resources.

  7. Sustainable development and the nature of environmental legal principles

    Directory of Open Access Journals (Sweden)

    J Verschuuren

    2006-05-01

    . Principles can become rules over time, when directly applicable in concrete cases. The nine functions are following: 1. principles can enhance the normative power of statutory rules; 2. principles can help to fill in open or unclear statutory rules; 3. principles can increase legal certainty and enhance the legitimacy of decision-making; 4. principles form the basis for new statutory rules; 5. principles give guidance to self-regulation; 6. principles create flexibility in the law; 7. principles help to implement international obligations; 8. principles stimulate the integration of environmental considerations into other policy fields; 9. principles are necessary to pursue an ideal. Principles thus influence the meaning of a rule but, at the same time, the application of a rule in a concrete case gives the relevant principle a clearer meaning than the principle has on its own. This goes for rules in various legal documents, such as acts and regulations, as well as transnational regulations, and self regulatory rules. Principles thus are dynamic beacons in a wild ocean of ever changing concrete environmental rules. Although the underlying ideal of sustainable development has a rather anthropocentric character, the danger of influencing environmental legal principles (and through principles legal rules and policies as well in a highly anthropocentric way is small. Firstly, because man is an inseparable part of nature and is very much dependent on balanced and intact ecosystems, especially when future generations are considered as well. Secondly, there is a moral relationship between man and nature. Natural objects have an inherent value: not destroying these objects contributes to the virtue of man. The ecological aspects of the ideal of sustainable development can be sufficiently advanced in decision-making processes by governmental authorities and courts, because most principles that rule environmental decision-making processes create enough room to take into account the

  8. Principles of Sociology in Systems Engineering

    Science.gov (United States)

    Watson, Michael D.; Andrews, James G.; Larsen, Jordan A.

    2017-01-01

    Systems engineering involves both the integration of the system and the integration of the disciplines which develop and operate the system. Integrating the disciplines is a sociological effort to bring together different groups, often with different terminology, to achieve a common goal, the system. The focus for the systems engineer is information flow through the organization, between the disciplines, to ensure the system is developed and operated with all relevant information informing system decisions. Robert K. Merton studied the sociological principles of the sciences and the sociological principles he developed apply to systems engineering. Concepts such as specification of ignorance, common terminology, opportunity structures, role-sets, and the reclama (reconsideration) process are all important sociological approaches that should be employed by the systems engineer. In bringing the disciplines together, the systems engineer must also be wary of social ambivalence, social anomie, social dysfunction, insider-outsider behavior, unintended consequences, and the self-fulfilling prophecy. These sociological principles provide the systems engineer with key approaches to manage the information flow through the organization as the disciplines are integrated and share their information. This also helps identify key sociological barriers to information flow through the organization. This paper will discuss this theoretical basis for the application of sociological principles to systems engineering.

  11. The Principle-Based Method of Practical Ethics.

    Science.gov (United States)

    Spielthenner, Georg

    2017-09-01

    This paper is about the methodology of doing practical ethics. There is a variety of methods employed in ethics. One of them is the principle-based approach, which has an established place in ethical reasoning. In everyday life, we often judge the rightness and wrongness of actions by their conformity to principles, and the appeal to principles plays a significant role in practical ethics, too. In this paper, I try to provide a better understanding of the nature of principle-based reasoning. To accomplish this, I show in the first section that these principles can be applied to cases in a meaningful and sufficiently precise way. The second section discusses the question how relevant applying principles is to the resolution of ethical issues. This depends on their nature. I argue that the principles under consideration in this paper should be interpreted as presumptive principles and I conclude that although they cannot be expected to bear the weight of definitely resolving ethical problems, these principles can nevertheless play a considerable role in ethical research.

    Quantum mechanics and classical mechanics are distinctly different theories, but the correspondence principle states that quantum particles behave classically in the limit of high quantum number. In recent years much research has been done on extending both quantum and classical mechanics into the complex domain. These complex extensions continue to exhibit a correspondence, and this correspondence becomes more pronounced in the complex domain. The association between complex quantum mechanics and complex classical mechanics is subtle and demonstrating this relationship requires the use of asymptotics beyond all orders.

    The establishment of a sector-specific network access regulation significantly contributes to the development of vigorous competition in telecommunications services. Even in the sectors of electricity and natural gas hopes are placed on a regulation. Recognising this, in early 2010, a contract for a legal opinion concluded on behalf of the Energieeffizienzverband fuer Waerme, Kaelte und KWK e.V. (Frankfurt/Main, Federal Republic of Germany). This legal opinion should examine the following questions: (1) To what extent can the effect of the substitution ban also be used for the enforcement of access requirements?; (2) Is the heat supply system a key organization in line with paragraph 19 Sect. 4 No 4 GWB (GWB = Restriction of Competition)? (3) May the network access be denied on economic grounds in the way of objective justification? (4) How far may in particular environmental and beyond considerations of economic standing aspects be used? Based on these particular issues, especially, grid access requirements are traced. The author of the contribution under consideration investigates the following issues: (a) To what extent can claims on supply with or acceptance of district heating be derived from anti-trust standards?; (b) What are the impacts of the specialties of district heating on the application of the antitrust law? (d) To what extent does the antitrust law interact with the regulations of energy law and its objectives?.

    We propose the principle, the law of statistical balance for basic physical observables, which specifies quantum statistical theory among all other statistical theories of measurements. It seems that this principle might play in quantum theory the role that is similar to the role of Einstein's relativity principle.

    Mechanical excavation of rock today includes several methods such as tunnel boring, raiseboring, roadheading and various continuous mining systems. Of these raiseboring is one potential technique for excavating shafts in the repository for spent nuclear fuel and dry blind boring is promising technique for excavation of deposition holes, as demonstrated in the Research Tunnel at Olkiluoto. In addition, there is potential for use of other mechanical excavation techniques in different parts of the repository. One of the main objectives of this study was to analyze the factors which affect the feasibility of mechanical rock excavation in hard rock conditions and to enhance the understanding of factors which affect rock cutting so as to provide an improved basis for excavator performance prediction modeling. The study included the following four main topics: (a) phenomenological model based on similarity analysis for roller disk cutting, (b) rock mass properties which affect rock cuttability and tool life, (c) principles for linear and field cutting tests and performance prediction modeling and (d) cutter head lacing design procedures and principles. As a conclusion of this study, a test rig was constructed, field tests were planned and started up. The results of the study can be used to improve the performance prediction models used to assess the feasibility of different mechanical excavation techniques at various repository investigation sites.

Life in the society means more than a simple coexistence of human beings, it actually means living together, collaborating and cooperating; that is why I always have to relate to other people and to be aware that only by limiting my freedom of action, the others freedom is feasible. Neminem laedere should be a principle of life for each of us. The individual is a responsible being. But responsibility exceeds legal prescriptions. Romanian Constitution underlines that I have to exercise my rights and freedoms in good faith, without infringing the rights and freedoms of others. The legal norm, developer of the constitutional principles, is endowed with sanction, which grants it exigibility. But I wonder: If I choose to obey the law, is my decision essentially determined only due of the fear of punishment? Is it not because I am a rational being, who developed during its life a conscience towards values, and thus I understand that I have to respect the law and I choose to comply with it?

  11. A survey of variational principles

    Lewins, J.D.

    1993-01-01

    In this article survey of variational principles has been given. Variational principles play a significant role in mathematical theory with emphasis on the physical aspects. There are two principals used i.e. to represent the equation of the system in a succinct way and to enable a particular computation in the system to be carried out with greater accuracy. The survey of variational principles has ranged widely from its starting point in the Lagrange multiplier to optimisation principles. In an age of digital computation, these classic methods can be adapted to improve such calculations. We emphasize particularly the advantage of basic finite element methods on variational principles.

    It is shown that the Bianchi 9 model universe satisfies the Mach principle. These closed rotating universes were previously thought to be counter-examples to the principle. The Mach principle is satisfied because the angular momentum of the rotating matter is compensated by the effective angular momentum of gravitational waves. A new formulation of the Mach principle is given that is based on the field theory interpretation of general relativity. Every closed universe with 3-sphere topology is shown to satisfy this formulation of the Mach principle. It is shown that the total angular momentum of the matter and gravitational waves in a closed 3-sphere topology universe is zero

    The survey of variational principles has ranged widely from its starting point in the Lagrange multiplier to optimisation principles. In an age of digital computation, these classic methods can be adapted to improve such calculations. We emphasize particularly the advantage of basing finite element methods on variational principles, especially if, as maximum and minimum principles, these can provide bounds and hence estimates of accuracy. The non-symmetric (and hence stationary rather than extremum principles) are seen however to play a significant role in optimisation theory. (Orig./A.B.)

  14. The base rate principle and the fairness principle in social judgment.

    Meet Jonathan and Elizabeth. One person is a doctor and the other is a nurse. Who is the doctor? When nothing else is known, the base rate principle favors Jonathan to be the doctor and the fairness principle favors both individuals equally. However, when individuating facts reveal who is actually the doctor, base rates and fairness become irrelevant, as the facts make the correct answer clear. In three experiments, explicit and implicit beliefs were measured before and after individuating facts were learned. These facts were either stereotypic (e.g., Jonathan is the doctor, Elizabeth is the nurse) or counterstereotypic (e.g., Elizabeth is the doctor, Jonathan is the nurse). Results showed that before individuating facts were learned, explicit beliefs followed the fairness principle, whereas implicit beliefs followed the base rate principle. After individuating facts were learned, explicit beliefs correctly aligned with stereotypic and counterstereotypic facts. Implicit beliefs, however, were immune to counterstereotypic facts and continued to follow the base rate principle. Having established the robustness and generality of these results, a fourth experiment verified that gender stereotypes played a causal role: when both individuals were male, explicit and implicit beliefs alike correctly converged with individuating facts. Taken together, these experiments demonstrate that explicit beliefs uphold fairness and incorporate obvious and relevant facts, but implicit beliefs uphold base rates and appear relatively impervious to counterstereotypic facts.

    Full Text Available The problem premises and the objectives followed: the idea of inserting the equality principle between the freedom and the justice principles is manifested in positive law in two stages, as a general idea of all judicial norms and as requirement of the owner of a subjective right of the applicants of an objective law. Equality in face of the law and of public authorities can not involve the idea of standardization, of uniformity, of enlisting of all citizens under the mark of the same judicial regime, regardless of their natural or socio-professional situation. Through the Beijing Platform and the position documents of the European Commission we have defined the integrative approach of equality as representing an active and visible integration of the gender perspective in all sectors and at all levels. The research methods used are: the conceptualist method, the logical method and the intuitive method necessary as means of reasoning in order to argue our demonstration. We have to underline the fact that the system analysis of the research methods of the judicial phenomenon doesn’t agree with “value ranking”, because one value cannot be generalized in rapport to another. At the same time, we must fight against a methodological extremism. The final purpose of this study is represented by the reaching of the perfecting/excellence stage by all individuals through the promotion of equality and freedom. This supposes the fact that the existence of a non-discrimination favourable frame (fairness represents a means and a condition of self-determination, and the state of perfection/excellency is a result of this self-determination, the condition necessary for the obtaining of this nondiscrimination frame for all of us and in conditions of freedom for all individuals, represents the same condition that promotes the state of perfection/excellency. In conclusion we may state the fact that the equality principle represents a true catalyst of the

    A paramount topic in quantum foundations, rooted in the study of the Einstein-Podolsky-Rosen (EPR) paradox and Bell inequalities, is that of characterizing quantum theory in terms of the spacelike correlations it allows. Here, we show that to focus only on spacelike correlations is not enough: we explicitly construct a toy model theory that, while not contradicting classical and quantum theories at the level of spacelike correlations, still displays an anomalous behavior in its timelike correlations. We call this anomaly, quantified in terms of a specific communication game, the "hypersignaling" phenomena. We hence conclude that the "principle of quantumness," if it exists, cannot be found in spacelike correlations alone: nontrivial constraints need to be imposed also on timelike correlations, in order to exclude hypersignaling theories.

    Positron emission tomography (PET) is a procedure in nuclear medicine, which is applied predominantly in oncological diagnostics. In the form of modern hybrid machines, such as PET computed tomography (PET/CT) and PET magnetic resonance imaging (PET/MRI) it has found wide acceptance and availability. The PET procedure is more than just another imaging technique, but a functional method with the capability for quantification in addition to the distribution pattern of the radiopharmaceutical, the results of which are used for therapeutic decisions. A profound knowledge of the principles of PET including the correct indications, patient preparation, and possible artifacts is mandatory for the correct interpretation of PET results.

    The world is chiral. Most of the molecules in it are chiral, and asymmetric synthesis is an important means by which enantiopure chiral molecules may be obtained for study and sale. Using examples from the literature of asymmetric synthesis, this book presents a detailed analysis of the factors that govern stereoselectivity in organic reactions. After an explanation of the basic physical-organic principles governing stereoselective reactions, the authors provide a detailed, annotated glossary of stereochemical terms. A chapter on "Practical Aspects of Asymmetric Synthesis" provides a critical overview of the most common methods for the preparation of enantiomerically pure compounds, techniques for analysis of stereoisomers using chromatographic, spectroscopic, and chiroptical methods. The authors then present an overview of the most important methods in contemporary asymmetric synthesis organized by reaction type. Thus, there are four chapters on carbon-carbon bond forming reactions, one chapter on reductions...

    2007-01-01

    Emulsions are generally made out of two immiscible fluids like oil and water, one being dispersed in the second in the presence of surface-active compounds.They are used as intermediate or end products in a huge range of areas including the food, chemical, cosmetic, pharmaceutical, paint, and coating industries. Besides the broad domain of technological interest, emulsions are raising a variety of fundamental questions at the frontier between physics and chemistry. This book aims to give an overview of the most recent advances in emulsion science. The basic principles, covering aspects of emulsions from their preparation to their destruction, are presented in close relation to both the fundamental physics and the applications of these materials. The book is intended to help scientists and engineers in formulating new materials by giving them the basics of emulsion science.

    2013-01-01

    Principles of Bioenergetics summarizes one of the quickly growing branches of modern biochemistry. Bioenergetics concerns energy transductions occurring in living systems and this book pays special attention to molecular mechanisms of these processes. The main subject of the book is the "energy coupling membrane" which refers to inner membranes of intracellular organelles, for example, mitochondria and chloroplasts. Cellular cytoplasmic membranes where respiratory and photosynthetic energy transducers, as well as ion-transporting ATP-synthases (ATPases) are also part of this membrane. Significant attention is paid to the alternative function of mitochondria as generators of reactive oxygen species (ROS) that mediate programmed death of cells (apoptosis and necrosis) and organisms (phenoptosis). The latter process is considered as a key mechanism of aging which may be suppressed by mitochondria-targeted antioxidants.

    A variational principle for mechanical systems and fields subject to nonholonomic constraints is found, providing Chetaev-reduced equations as equations for extremals. Investigating nonholonomic variations of the Chetaev type and their properties, we develop foundations of the calculus of variations on constraint manifolds, modelled as fibred submanifolds in jet bundles. This setting is appropriate to study general first-order 'nonlinear nonitegrable constraints' that locally are given by a system of first-order ordinary or partial differential equations. We obtain an invariant constrained first variation formula and constrained Euler-Lagrange equations both in intrinsic and coordinate forms, and show that the equations are the same as Chetaev equations 'without Lagrange multipliers', introduced recently by other methods. We pay attention to two possible settings: first, when the constrained system arises from an unconstrained Lagrangian system defined in a neighbourhood of the constraint, and second, more generally, when an 'internal' constrained system on the constraint manifold is given. In the latter case a corresponding unconstrained system need not be a Lagrangian, nor even exist. We also study in detail an important particular case: nonholonomic constraints that can be alternatively modelled by means of (co)distributions in the total space of the fibred manifold; in nonholonomic mechanics this happens whenever constraints affine in velocities are considered. It becomes clear that (and why) if the distribution is completely integrable (= the constraints are semiholonomic), the principle of virtual displacements holds and can be used to obtain the constrained first variational formula by a more or less standard procedure, traditionally used when unconstrained or holonomic systems are concerned. If, however, the constraint is nonintegrable, no significant simplifications are available. Among others, some properties of nonholonomic

    Dynamical modeling of neural systems and brain functions has a history of success over the last half century. This includes, for example, the explanation and prediction of some features of neural rhythmic behaviors. Many interesting dynamical models of learning and memory based on physiological experiments have been suggested over the last two decades. Dynamical models even of consciousness now exist. Usually these models and results are based on traditional approaches and paradigms of nonlinear dynamics including dynamical chaos. Neural systems are, however, an unusual subject for nonlinear dynamics for several reasons: (i) Even the simplest neural network, with only a few neurons and synaptic connections, has an enormous number of variables and control parameters. These make neural systems adaptive and flexible, and are critical to their biological function. (ii) In contrast to traditional physical systems described by well-known basic principles, first principles governing the dynamics of neural systems are unknown. (iii) Many different neural systems exhibit similar dynamics despite having different architectures and different levels of complexity. (iv) The network architecture and connection strengths are usually not known in detail and therefore the dynamical analysis must, in some sense, be probabilistic. (v) Since nervous systems are able to organize behavior based on sensory inputs, the dynamical modeling of these systems has to explain the transformation of temporal information into combinatorial or combinatorial-temporal codes, and vice versa, for memory and recognition. In this review these problems are discussed in the context of addressing the stimulating questions: What can neuroscience learn from nonlinear dynamics, and what can nonlinear dynamics learn from neuroscience?

  7. Fault Management Guiding Principles

    2011-01-01

    Regardless of the mission type: deep space or low Earth orbit, robotic or human spaceflight, Fault Management (FM) is a critical aspect of NASA space missions. As the complexity of space missions grows, the complexity of supporting FM systems increase in turn. Data on recent NASA missions show that development of FM capabilities is a common driver for significant cost overruns late in the project development cycle. Efforts to understand the drivers behind these cost overruns, spearheaded by NASA's Science Mission Directorate (SMD), indicate that they are primarily caused by the growing complexity of FM systems and the lack of maturity of FM as an engineering discipline. NASA can and does develop FM systems that effectively protect mission functionality and assets. The cost growth results from a lack of FM planning and emphasis by project management, as well the maturity of FM as an engineering discipline, which lags behind the maturity of other engineering disciplines. As a step towards controlling the cost growth associated with FM development, SMD has commissioned a multi-institution team to develop a practitioner's handbook representing best practices for the end-to-end processes involved in engineering FM systems. While currently concentrating primarily on FM for science missions, the expectation is that this handbook will grow into a NASA-wide handbook, serving as a companion to the NASA Systems Engineering Handbook. This paper presents a snapshot of the principles that have been identified to guide FM development from cradle to grave. The principles range from considerations for integrating FM into the project and SE organizational structure, the relationship between FM designs and mission risk, and the use of the various tools of FM (e.g., redundancy) to meet the FM goal of protecting mission functionality and assets.

    2009-01-01

    One of the most exciting events in neurosciences over the past few years has been the discovery of a mechanism that unifies action perception and action execution. The essence of this 'mirror' mechanism is as follows: whenever individuals observe an action being done by someone else, a set of neurons that code for that action is activated in the observers' motor system. Since the observers are aware of the outcome of their motor acts, they also understand what the other individual is doing without the need for intermediate cognitive mediation. In this Review, after discussing the most pertinent data concerning the mirror mechanism, we examine the clinical relevance of this mechanism. We first discuss the relationship between mirror mechanism impairment and some core symptoms of autism. We then outline the theoretical principles of neurorehabilitation strategies based on the mirror mechanism. We conclude by examining the relationship between the mirror mechanism and some features of the environmental dependency syndromes.

    2018-01-01

    Abstract Background and objectives Evolutionary medicine is a rapidly growing field that uses the principles of evolutionary biology to better understand, prevent and treat disease, and that uses studies of disease to advance basic knowledge in evolutionary biology. Over-arching principles of evolutionary medicine have been described in publications, but our study is the first to systematically elicit core principles from a diverse panel of experts in evolutionary medicine. These principles should be useful to advance recent recommendations made by The Association of American Medical Colleges and the Howard Hughes Medical Institute to make evolutionary thinking a core competency for pre-medical education. Methodology The Delphi method was used to elicit and validate a list of core principles for evolutionary medicine. The study included four surveys administered in sequence to 56 expert panelists. The initial open-ended survey created a list of possible core principles; the three subsequent surveys winnowed the list and assessed the accuracy and importance of each principle. Results Fourteen core principles elicited at least 80% of the panelists to agree or strongly agree that they were important core principles for evolutionary medicine. These principles over-lapped with concepts discussed in other articles discussing key concepts in evolutionary medicine. Conclusions and implications This set of core principles will be helpful for researchers and instructors in evolutionary medicine. We recommend that evolutionary medicine instructors use the list of core principles to construct learning goals. Evolutionary medicine is a young field, so this list of core principles will likely change as the field develops further. PMID:29493660

    Guiding principles are arguably central to the development of any health service. The aim of this article is to report on the outcomes of a youth mental health (YMH) community of practice (CoP), which identified a range of guiding principles that provide a clear point of comparison for the only other set of principles for YMH service delivery proposed to date. A YMH CoP was established in 2010 as part of the Victorian State Government approach to improving YMH care. An initial literature search was undertaken to locate articles on YMH service delivery. A number of common themes were identified, which the YMH community of practice (YMHCoP) members then elaborated upon by drawing from their collective experience of the YMH sector. The resultant themes were then refined through subsequent group discussions to derive a definitive set of guiding principles. These principles were then augmented by a second literature search conducted in July 2015. Fifteen key themes were derived from the initial literature search and YMH CoP discussions. These were refined by the YMH CoP to produce 10 guiding principles for YMH service development. These are discussed through reference to the relevant literature, using the only other article on principles of YMH service delivery as a notable point of comparison. The 10 principles identified may be useful for quality improvement and are likely to have international relevance. We suggest the timely pursuit of an international consensus on guiding principles for service delivery under the auspices of a peak body for YMH. © 2017 John Wiley & Sons Australia, Ltd.

    innovation, highly restrictive administrative procedures, and a waste of funds on the search for the utopian goal of zero risk. Other drawbacks are more insidious. The precautionary principle could contribute to a general feeling of anxiety and unease in the population. It could be used by campaigns to manipulate public opinion in favor of a particular commercial interest or ideology. Furthermore, practitioners and public policy makers could be led to make choices not dictated by a search for the optimal solution but rather a solution that would protect them from future accusations (the so-called umbrella phenomenon). On the international level, the precautionary principle must not be used to mask protectionism. Nevertheless, a clear advantage of the precautionary principle is that it requires decision-makers to explain the rationale behind their decisions, to quantify the risks, and to provide objective information. However, the physician must not be tempted to make patients sign documents certifying that they have been given all relevant information on his or her diagnosis and treatment. This example underlines the role of legal texts and jurisprudence in the application of the precautionary principle. Finally, the precautionary principle implies new obligations for the State. In the field of health and healthcare, the State must undertake actions based on fully open and undisguised decision-making and provide complete information to the public. A pplication of the precautionary principle requires much discernment because the final outcome can be beneficial or harmful, depending on the way it is implemented. The precautionary principle, and its applications, must be precise and detailed within a well-defined framework.

    2000-01-01

    The German EnWG (energy industry law) for deregulation of the energy sector and implementation of the Internal Energy Market Directive of the EU contains an obligation to contract and make rules for establishing a legally binding system for access to and use of third parties of transmission and distribution networks in the competitive electricity market. The design of such contracts under private law as well as the grid code for network operation primarily being a matter of the contracting parties, the legal basis and opportunities for governmental supervisory functions are embodied in various laws. The legal analysis of this contribution examines the current situation and asks whether the existing provisions of the German BGB (Civil Code), antitrust law and the EnWG offer practicable means in case of need for governmental supervisory action in order to ensure evolution and adherence to a legal framework that will ensure the objectives of the politically willed deregulation of the energy sector and foster development of an open market serving the public welfare.

    Lakes Superior, Huron, Michigan, Ontario, and Erie together form North America's Great Lakes, a region that contains 20% of the world's fresh surface water and is home to roughly one quarter of the U.S. population (Figure 1). Supporting a $4 billion sport fishing industry, plus $16 billion annually in boating, 1.5 million U.S. jobs, and $62 billion in annual wages directly, the Great Lakes form the backbone of a regional economy that is vital to the United States as a whole (see http://www.miseagrant.umich.edu/downloads/economy/11-708-Great-Lakes-Jobs.pdf). Yet the grandeur and importance of this freshwater resource are little understood, not only by people in the rest of the country but also by many in the region itself. To help address this lack of knowledge, the Centers for Ocean Sciences Education Excellence (COSEE) Great Lakes, supported by the U.S. National Science Foundation and the National Oceanic and Atmospheric Administration, developed literacy principles for the Great Lakes to serve as a guide for education of students and the public. These “Great Lakes Literacy Principles” represent an understanding of the Great Lakes' influences on society and society's influences on the Great Lakes.

  20. Advertisement without Ethical Principles?

    2007-10-01

    Full Text Available The article replies to the question, whether the advertisement can exist without ethical principles or ethics should be the basis of the advertisement. One can say that the ethical opinion of the advertisement does not depend on content and the form of advertising content exclusively, but also on recipients consciousness. The advertisement appeals to the emotions more than to the intellect, thus restricting the area of conscious and based on rational premises choice, so it is morally bad. It is not that the moral evil immanently underlines the advertisement, but it concerns the mechanisms which cause that the advertisement turns out to be effective. The only admissible form of the advertisement would be the reliable full information about the advantages and flaws of the concrete advertised product. The only admissible form of the advertisement would be the reliable full information about the advantages and defects of the concrete advertised product. The most serious difficulty connected with the ethical opinion of the advertisement is the fact that the advertisement is the indispensable link of the present economy, and everyone who accepts the free market and perceives the positives of the economic growth, should also accept the advertisement. The advertisement constitutes the element of the economic activity, so in consequence the responsibility first of all lies with enterprises for its far-reaching results.

  1. Principles of Bioremediation Assessment

    Madsen, E. L.

    2001-12-01

    Although microorganisms have successfully and spontaneously maintained the biosphere since its inception, industrialized societies now produce undesirable chemical compounds at rates that outpace naturally occurring microbial detoxification processes. This presentation provides an overview of both the complexities of contaminated sites and methodological limitations in environmental microbiology that impede the documentation of biodegradation processes in the field. An essential step toward attaining reliable bioremediation technologies is the development of criteria which prove that microorganisms in contaminated field sites are truly active in metabolizing contaminants of interest. These criteria, which rely upon genetic, biochemical, physiological, and ecological principles and apply to both in situ and ex situ bioremediation strategies include: (i) internal conservative tracers; (ii) added conservative tracers; (iii) added radioactive tracers; (iv) added isotopic tracers; (v) stable isotopic fractionation patterns; (vi) detection of intermediary metabolites; (vii) replicated field plots; (viii) microbial metabolic adaptation; (ix) molecular biological indicators; (x) gradients of coreactants and/or products; (xi) in situ rates of respiration; (xii) mass balances of contaminants, coreactants, and products; and (xiii) computer modeling that incorporates transport and reactive stoichiometries of electron donors and acceptors. The ideal goal is achieving a quantitative understanding of the geochemistry, hydrogeology, and physiology of complex real-world systems.

    The Iceberg Principles connect spirituality and science in a way that proves that the energy, which is the substance of the Universe, really is Love - not sweet, syrupy, candy-and-roses kind of love but the most powerful force in the Universe. Love without expression is meaningless. This is why the Big Bang was the only logical outcome. Love had to become reflected in dimensionality. With the Big Bang a 4:96 ratio was created between the dimensional and non-dimensional realms. This ratio between visibility and invisibility the ratio of an iceberg also applies to human beings. Only four percent of who we are is visible. Our physical DNA describes us but it does not define us. What defines us are our characteristics, our gifts, and talents - the spiritual DNA. This is invisible but makes up ninety-six percent of who we are. Our talents are not accidental; our life purpose is to express them. Just as the Universe emerges into dimensionality, constantly creating galaxies at millions of miles a minute, we are al...

    Surveys of taxonomic groups of animals have shown that contrary to the opinion of most gerontologists aging is not a genuine trait. The process of aging is not universal and its mechanisms have not been widely conserved among species. All life forms are subject to extrinsic and intrinsic destructive forces. Destructive effects of stochastic events are visible only when allowed by the specific life program of an organism. Effective life programs of immortality and high longevity eliminate the impact of unavoidable damage. Organisms that are capable of agametic reproduction are biologically immortal. Mortality of an organism is clearly associated with terminal specialisation in sexual reproduction. The longevity phenotype that is not accompanied by symptoms of senescence has been observed in those groups of animals that continue to increase their body size after reaching sexual maturity. This is the result of enormous regeneration abilities of both of the above-mentioned groups. Senescence is observed when: (i) an organism by principle switches off the expression of existing growth and regeneration programs, as in the case of imago formation in insect development; (ii) particular programs of growth and regeneration of progenitors are irreversibly lost, either partially or in their entirety, in mammals and birds. “We can't solve problems by using the same kind of thinking we used when we created them.” (Ascribed to Albert Einstein) PMID:27017907

    Hinman, Jason D; Rost, Natalia S; Leung, Thomas W; Montaner, Joan; Muir, Keith W; Brown, Scott; Arenillas, Juan F; Feldmann, Edward; Liebeskind, David S

    The era of precision medicine has arrived and conveys tremendous potential, particularly for stroke neurology. The diagnosis of stroke, its underlying aetiology, theranostic strategies, recurrence risk and path to recovery are populated by a series of highly individualised questions. Moreover, the phenotypic complexity of a clinical diagnosis of stroke makes a simple genetic risk assessment only partially informative on an individual basis. The guiding principles of precision medicine in stroke underscore the need to identify, value, organise and analyse the multitude of variables obtained from each individual to generate a precise approach to optimise cerebrovascular health. Existing data may be leveraged with novel technologies, informatics and practical clinical paradigms to apply these principles in stroke and realise the promise of precision medicine. Importantly, precision medicine in stroke will only be realised once efforts to collect, value and synthesise the wealth of data collected in clinical trials and routine care starts. Stroke theranostics, the ultimate vision of synchronising tailored therapeutic strategies based on specific diagnostic data, demand cerebrovascular expertise on big data approaches to clinically relevant paradigms. This review considers such challenges and delineates the principles on a roadmap for rational application of precision medicine to stroke and cerebrovascular health.

  6. Energy principle with included boundary conditions

    International Nuclear Information System (INIS)

    Lehnert, B.

    1994-01-01

    Earlier comments by the author on the limitations of the classical form of the extended energy principle are supported by a complementary analysis on the potential energy change arising from free-boundary displacements of a magnetically confined plasma. In the final formulation of the extended principle, restricted displacements, satisfying pressure continuity by means of plasma volume currents in a thin boundary layer, are replaced by unrestricted (arbitrary) displacements which can give rise to induced surface currents. It is found that these currents contribute to the change in potential energy, and that their contribution is not taken into account by such a formulation. A general expression is further given for surface currents induced by arbitrary displacements. The expression is used to reformulate the energy principle for the class of displacements which satisfy all necessary boundary conditions, including that of the pressure balance. This makes a minimization procedure of the potential energy possible, for the class of all physically relevant test functions which include the constraints imposed by the boundary conditions. Such a procedure is also consistent with a corresponding variational calculus. (Author)

  7. Basic principles of radiation protection in Canada

    International Nuclear Information System (INIS)

    1990-03-01

    The major goal of radiation protection in Canada is to ensure that individuals are adequately protected against the harm that might arise from unwarranted exposure to ionizing radiation. This report deals with the basic principles and organizations involved in protection against ionizing radiation. Three basic principles of radiation protection are: 1) that no practice shall be adopted unless its introduction produces a positive net benefit for society, 2) that all exposures shall be kept as low as reasonably achievable, relevant economic and social factors being taken into account, and 3) that doses to individuals should not exceed specified annual limits. The limit for radiation workers is currently 50 mSv per year, and exposures of the general public should not exceed a small fraction of that of radiation workers. Other specific areas in radiation protection which have received considerable attention in Canada include limitations on collective dose (the sum of the individual doses for all exposed individuals), exemption rules for extremely small radiation doses or amounts of radioactive materials, occupational hazards in uranium mining, and special rules for protection of the foetus in pregnant female radiation workers. Implementation of radiation protection principles in Canada devolves upon the Atomic Energy Control Board, the Department of National Health and Welfare, provincial authorities, licensees and radiation workers. A brief description is given of the roles of each of these groups

  9. The Principle of General Tovariance

    Science.gov (United States)

    Heunen, C.; Landsman, N. P.; Spitters, B.

    2008-06-01

    We tentatively propose two guiding principles for the construction of theories of physics, which should be satisfied by a possible future theory of quantum gravity. These principles are inspired by those that led Einstein to his theory of general relativity, viz. his principle of general covariance and his equivalence principle, as well as by the two mysterious dogmas of Bohr's interpretation of quantum mechanics, i.e. his doctrine of classical concepts and his principle of complementarity. An appropriate mathematical language for combining these ideas is topos theory, a framework earlier proposed for physics by Isham and collaborators. Our principle of general tovariance states that any mathematical structure appearing in the laws of physics must be definable in an arbitrary topos (with natural numbers object) and must be preserved under so-called geometric morphisms. This principle identifies geometric logic as the mathematical language of physics and restricts the constructions and theorems to those valid in intuitionism: neither Aristotle's principle of the excluded third nor Zermelo's Axiom of Choice may be invoked. Subsequently, our equivalence principle states that any algebra of observables (initially defined in the topos Sets) is empirically equivalent to a commutative one in some other topos.

    1980-01-01

    After introducing general versions of three fundamental quantum postulates - the superposition principle, the uncertainty principle and the complementarity principle - the question of whether the three principles are sufficiently strong to restrict the general Mackey description of quantum systems to the standard Hilbert-space quantum theory is discussed. An example which shows that the answer must be negative is constructed. An abstract version of the projection postulate is introduced and it is demonstrated that it could serve as the missing physical link between the general Mackey description and the standard quantum theory.

  13. The inconstant "principle of constancy".

    Science.gov (United States)

    Kanzer, M

    1983-01-01

    A review of the principle of constancy, as it appeared in Freud's writings, shows that it was inspired by his clinical observations, first with Breuer in the field of cathartic therapy and then through experiences in the early usage of psychoanalysis. The recognition that memories repressed in the unconscious created increasing tension, and that this was relieved with dischargelike phenomena when the unconscious was made conscious, was the basis for his claim to originality in this area. The two principles of "neuronic inertia" Freud expounded in the Project (1895), are found to offer the key to the ambiguous definition of the principle of constancy he was to offer in later years. The "original" principle, which sought the complete discharge of energy (or elimination of stimuli), became the forerunner of the death drive; the "extended" principle achieved balances that were relatively constant, but succumbed in the end to complete discharge. This was the predecessor of the life drives. The relation between the constancy and pleasure-unpleasure principles was maintained for twenty-five years largely on an empirical basis which invoked the concept of psychophysical parallelism between "quantity" and "quality." As the links between the two principles were weakened by clinical experiences attendant upon the growth of ego psychology, a revision of the principle of constancy was suggested, and it was renamed the Nirvana principle. Actually it was shifted from alignment with the "extended" principle of inertia to the original, so that "constancy" was incongruously identified with self-extinction. The former basis for the constancy principle, the extended principle of inertia, became identified with Eros. Only a few commentators seem aware of this radical transformation, which has been overlooked in the Standard Edition of Freud's writings. Physiological biases in the history and conception of the principle of constancy are noted in the Standard Edition. The historical

  14. Principles of animal extrapolation

    Energy Technology Data Exchange (ETDEWEB)

    Calabrese, E.J.

    1991-01-01

    Animal Extrapolation presents a comprehensive examination of the scientific issues involved in extrapolating results of animal experiments to human response. This text attempts to present a comprehensive synthesis and analysis of the host of biomedical and toxicological studies of interspecies extrapolation. Calabrese's work presents not only the conceptual basis of interspecies extrapolation, but also illustrates how these principles may be better used in selection of animal experimentation models and in the interpretation of animal experimental results. The book's theme centers around four types of extrapolation: (1) from average animal model to the average human; (2) from small animals to large ones; (3) from high-risk animal to the high risk human; and (4) from high doses of exposure to lower, more realistic, doses. Calabrese attacks the issues of interspecies extrapolation by dealing individually with the factors which contribute to interspecies variability: differences in absorption, intestinal flora, tissue distribution, metabolism, repair mechanisms, and excretion. From this foundation, Calabrese then discusses the heterogeneticity of these same factors in the human population in an attempt to evaluate the representativeness of various animal models in light of interindividual variations. In addition to discussing the question of suitable animal models for specific high-risk groups and specific toxicological endpoints, the author also examines extrapolation questions related to the use of short-term tests to predict long-term human carcinogenicity and birth defects. The book is comprehensive in scope and specific in detail; for those environmental health professions seeking to understand the toxicological models which underlay health risk assessments, Animal Extrapolation is a valuable information source.

  15. The equivalence principle

    International Nuclear Information System (INIS)

    Smorodinskij, Ya.A.

    1980-01-01

    The prerelativistic history of the equivalence principle (EP) is presented briefly. Its role in history of the general relativity theory (G.R.T.) discovery is elucidated. A modern idea states that the ratio of inert and gravitational masses does not differ from 1 at least up to the 12 sign after comma. Attention is paid to the difference of the gravitational field from electromagnetic one. The difference is as follows, the energy of the gravitational field distributed in space is the source of the field. These fields always interact at superposition. Electromagnetic fields from different sources are put together. On the basis of EP it is established the Sun field interact with the Earth gravitational energy in the same way as with any other one. The latter proves the existence of gravitation of the very gravitational field to a heavy body. A problem on gyroscope movement in the Earth gravitational field is presented as a paradox. The calculation has shown that gyroscope at satellite makes a positive precession, and its axis turns in an angle equal to α during a turn of the satellite round the Earth, but because of the space curvature - into the angle two times larger than α. A resulting turn is equal to 3α. It is shown on the EP basis that the polarization plane in any coordinate system does not turn when the ray of light passes in the gravitational field. Together with the historical value of EP noted is the necessity to take into account the requirements claimed by the EP at description of the physical world

  16. Relevance theory: pragmatics and cognition.

    Science.gov (United States)

    Wearing, Catherine J

    2015-01-01

    Relevance Theory is a cognitively oriented theory of pragmatics, i.e., a theory of language use. It builds on the seminal work of H.P. Grice(1) to develop a pragmatic theory which is at once philosophically sensitive and empirically plausible (in both psychological and evolutionary terms). This entry reviews the central commitments and chief contributions of Relevance Theory, including its Gricean commitment to the centrality of intention-reading and inference in communication; the cognitively grounded notion of relevance which provides the mechanism for explaining pragmatic interpretation as an intention-driven, inferential process; and several key applications of the theory (lexical pragmatics, metaphor and irony, procedural meaning). Relevance Theory is an important contribution to our understanding of the pragmatics of communication. © 2014 John Wiley & Sons, Ltd.

    Quantitative relationships illustrate Einstein's equivalence principle, relating it to Newton's ''fictitious'' forces arising from the use of noninertial frames, and to the form of the relativistic time dilatation in local Lorentz frames. The equivalence principle can be interpreted as the equivalence of general covariance to local Lorentz covariance, in a manner which is characteristic of Riemannian and pseudo-Riemannian geometries

  5. Two conceptions of legal principles

    Directory of Open Access Journals (Sweden)

    Spaić Bojan

    2017-01-01

    Full Text Available The paper discusses the classical understanding of legal principles as the most general norms of a legal order, confronting it with Dworkin's and Alexy's understanding of legal principles as prima facie, unconditional commands. The analysis shows that the common, classical conception brings into question the status of legal principles as norms, by disreguarding their usefulness in judicial reasoning, while, conversely, the latterhas significant import forlegal practice and consequently for legal dogmatics. It is argued that the heuristic fruitfulness of understanding principles as optimization commands thusbecomesapparent. When we understand the relation of priciples to the idea of proportionality, as thespecific mode of their application, which is different from the supsumtive mode of applying rules, the theory of legal principles advanced by Dworkin and Alexy appears therefore to be descriptively better than others, but not without its flaws.

  6. Quantum principles in field interactions

    International Nuclear Information System (INIS)

    Shirkov, D.V.

    1986-01-01

    The concept of quantum principle is intruduced as a principle whosee formulation is based on specific quantum ideas and notions. We consider three such principles, viz. those of quantizability, local gauge symmetry, and supersymmetry, and their role in the development of the quantum field theory (QFT). Concerning the first of these, we analyze the formal aspects and physical contents of the renormalization procedure in QFT and its relation to ultraviolet divergences and the renorm group. The quantizability principle is formulated as an existence condition of a self-consistent quantum version with a given mechanism of the field interaction. It is shown that the consecutive (from a historial point of view) use of these quantum principles puts still larger limitations on possible forms of field interactions

On internal control and comprehensive set of reasonable response to the organization and classification of internal control is absent. This leads to continue the search key components of the organization's internal control. The above basic concepts in publications on the organization of internal control were used in the formation of a set of principles of control. According to the requirements of the OECD field of internal control includes risk management, cost control, change in control, complete information to guarantee the effectiveness of internal control systems, providing the ability to make decisions and so on. COSO model contains an exhaustive list of five components. The results of the questionnaire trainees have provided compelling arguments for classifying and establishing relevant principles of organization and internal controls were rejected.

  12. Principles and guidelines for radioactive waste disposal facilities

    International Nuclear Information System (INIS)

    1988-06-01

    Four basic principles relevant to radioactive waste disposal identified. These principles cover the justification of the activity giving rise to the waste, the consideration of risk to present and future generations, the minimization of the need for intervention in the future, and the financial obligations of the licensee. The use of risk limits as opposed to dose limits associated with disposal is discussed, as are the concepts of critical group, de minimis, and ALARA, in the context of a waste disposal facility. Guidance is given on the selection of the preferred waste disposal concept from among several alternatives, and for judging proposed design improvements to the chosen concept

    1988-01-01

    Because of Shippingport's low electrical power rating (72 MWe), there has been some misunderstanding on the relevancy of the Shippingport Station Decommissioning Project (SSDP) to a modern 1175 MWe commercial pressurized water reactor (PWR) power station. This paper provides a comparison of the major components of the reactor plant of the 72 MWe Shippingport Atomic Power Station and an 1175 MWe nuclear plant and the relevancy of the Shippingport decommissioning as a demonstration project for the nuclear industry. For the purpose of this comparison, Portland General Electric Company's 1175 MWe Trojan Nuclear Plant at Rainier, Oregon, has been used as the reference nuclear power plant. 2 refs., 2 figs., 1 tab

    In 1968, Wilson and Jungner published 10 principles of screening that often represent the de facto starting point for screening decisions today; 50 years on, are these principles still the right ones? Our objectives were to review published work that presents principles for population-based screening decisions since Wilson and Jungner's seminal publication, and to conduct a Delphi consensus process to assess the review results. We conducted a systematic review and modified Delphi consensus process. We searched multiple databases for articles published in English in 1968 or later that were intended to guide population-based screening decisions, described development and modification of principles, and presented principles as a set or list. Identified sets were compared for basic characteristics (e.g., number, categorization), a citation analysis was conducted, and principles were iteratively synthesized and consolidated into categories to assess evolution. Participants in the consensus process assessed the level of agreement with the importance and interpretability of the consolidated screening principles. We identified 41 sets and 367 unique principles. Each unique principle was coded to 12 consolidated decision principles that were further categorized as disease/condition, test/intervention or program/system principles. Program or system issues were the focus of 3 of Wilson and Jungner's 10 principles, but comprised almost half of all unique principles identified in the review. The 12 consolidated principles were assessed through 2 rounds of the consensus process, leading to specific refinements to improve their relevance and interpretability. No gaps or missing principles were identified. Wilson and Jungner's principles are remarkably enduring, but increasingly reflect a truncated version of contemporary thinking on screening that does not fully capture subsequent focus on program or system principles. Ultimately, this review and consensus process provides a

    BACKGROUND: In 1968, Wilson and Jungner published 10 principles of screening that often represent the de facto starting point for screening decisions today; 50 years on, are these principles still the right ones? Our objectives were to review published work that presents principles for population-based screening decisions since Wilson and Jungner’s seminal publication, and to conduct a Delphi consensus process to assess the review results. METHODS: We conducted a systematic review and modified Delphi consensus process. We searched multiple databases for articles published in English in 1968 or later that were intended to guide population-based screening decisions, described development and modification of principles, and presented principles as a set or list. Identified sets were compared for basic characteristics (e.g., number, categorization), a citation analysis was conducted, and principles were iteratively synthesized and consolidated into categories to assess evolution. Participants in the consensus process assessed the level of agreement with the importance and interpretability of the consolidated screening principles. RESULTS: We identified 41 sets and 367 unique principles. Each unique principle was coded to 12 consolidated decision principles that were further categorized as disease/condition, test/intervention or program/system principles. Program or system issues were the focus of 3 of Wilson and Jungner’s 10 principles, but comprised almost half of all unique principles identified in the review. The 12 consolidated principles were assessed through 2 rounds of the consensus process, leading to specific refinements to improve their relevance and interpretability. No gaps or missing principles were identified. INTERPRETATION: Wilson and Jungner’s principles are remarkably enduring, but increasingly reflect a truncated version of contemporary thinking on screening that does not fully capture subsequent focus on program or system principles

  1. VARIATIONAL PRINCIPLE FOR PLANETARY INTERIORS

    International Nuclear Information System (INIS)

    Zeng, Li; Jacobsen, Stein B.

    2016-01-01

    In the past few years, the number of confirmed planets has grown above 2000. It is clear that they represent a diversity of structures not seen in our own solar system. In addition to very detailed interior modeling, it is valuable to have a simple analytical framework for describing planetary structures. The variational principle is a fundamental principle in physics, entailing that a physical system follows the trajectory, which minimizes its action. It is alternative to the differential equation formulation of a physical system. Applying the variational principle to the planetary interior can beautifully summarize the set of differential equations into one, which provides us some insight into the problem. From this principle, a universal mass–radius relation, an estimate of the error propagation from the equation of state to the mass–radius relation, and a form of the virial theorem applicable to planetary interiors are derived.

  6. The normative basis of the Precautionary Principle

    Energy Technology Data Exchange (ETDEWEB)

    Schomberg, Rene von [European Commission, Directorate General for Research, Brussels (Belgium)

    2006-09-15

    Precautionary measures are provisional measures by nature, and need to be regularly reviewed when scientific information either calls for relaxation or strengthening of those measures. Within the EU context, these provisional measures do not have a prefixed 'expiry' date: one can only lift precautionary measures if scientific knowledge has progressed to a point that one would be able to translate (former) uncertainties in terms of risk and adverse effects in terms of defined, consensual levels of harm/damage. Precautionary frameworks facilitate in particular deliberation at the science/policy/society interfaces to which risk management is fully connected. Applying the precautionary principle is to be seen as a normative risk management exercise which builds upon scientific risk assessments. An ongoing scientific and normative deliberation at the science/policy interface involves a shift in science centred debates on the probability of risks towards a science informed debate on uncertainties and plausible adverse effects: this means that decisions should not only be based on available data but on a broad scientific knowledge base including a variety of scientific disciplines. The invocation, implementation and application of the precautionary principle follows a progressive line of different levels of deliberations (which obviously can be interconnected to each other but are distinguished here for analytical purposes). I have listed these levels of deliberation in a table. The table provides a model for guiding all the relevant normative levels of deliberation which are all needed in order to eventually make the legitimate conclusions on the acceptability of products or processes. The table provides a progressive line of those levels of deliberations from the initial invocation of the precautionary principle at the political level down to level of risk management decisions but at the same time show their inter relatedness.

It is shown that the theory predicts both the geodetic and motional precession of general relativity to within factors of order 1. The significance of the gyro experiment is discussed from the point of view of metric theories of gravity and this is contrasted with its significance from the point of view of Mach's principle.

First, in teaching microeconomics, the tools of welfare economics should play a larger role than they have in the past. Second, in teaching macroeconomics, classical ideas should play a larger role than they have in the past. Third, in teaching all parts of the course, we instructors should be sure to stress the important principles and be careful not to overwhelm students with an excess of details.

    The aim of radiation protection is to avoid or to reduce the risks linked to ionizing radiation. In order to reduce these risks, the radiation protection uses three great principles: justification, optimization and limitation of radiation doses. to apply these principles, the radiation protection has regulatory and technical means adapted to three different categories of people: public, patients and workers. The nuclear safety authority elaborates the regulation, and carries out monitoring of the reliable application of radiation protection system. (N.C.)

    While still at school, most of us are deeply impressed by the underlying principles that so beautifully explain why the chemical elements are ordered as they are in the periodic table, and may wonder, with the theoretician Brian Goodwin, "whether there might be equally powerful principles that account for the awe-inspiring diversity of body forms in the living realm". We have considered the arguments for developmental principles, conclude that they do exist and have specifically identified features that may generate principles associated with Hox patterning of the main body axis in bilaterian metazoa in general and in the vertebrates in particular. We wonder whether this exercise serves any purpose. The features we discuss were already known to us as parts of developmental mechanisms and defining developmental principles (how, and at which level?) adds no insight. We also see little profit in the proposal by Goodwin that there are principles outside the emerging genetic mechanisms that need to be taken into account. The emerging developmental genetic hierarchies already reveal a wealth of interesting phenomena, whatever we choose to call them.

We show the practicality of the language by implementation of a reversible fast Fourier transform. Our results indicate that the reversible programming paradigm has fundamental properties that are relevant to many different areas of computer science....... features of the language include explicit post-condition assertions, direct access to an inverse semantics and the possibility of clean (i.e., garbage-free) computation of injective functions. We suggest the clean simulation of reversible Turing machines as a criterion for computing strength of reversible...

  19. Goals and Principles of Environmental Policy

    International Nuclear Information System (INIS)

    Zylicz, T.

    2010-01-01

    This paper looks at how contemporary environmental (including climate) policy problems are phrased in terms of effectiveness, efficiency, and equity. The latter three concepts have served as foci of theoretical discussions among economists who analyse these issues and identify criteria that determine relevant regulations and programmes adopted by governments. The paper starts with a discussion of Pigouvian taxation as model instrument used in order to solve policy problems. It analyses to what extent and under what circumstances alternative instruments - such as marketable pollution permits - can achieve environmental and climate goals while serving other purposes too. Coase theorem is used as a reference for discussing what government interventions are indeed indispensable to achieve both explicit and tacit policy goals. Popular principles and practically applied 'rules of thumb' - such as the Polluter Pays Principle - are then reviewed. The next part is devoted to examining market structures as they influence environmental outcomes of economic activities. This is followed by a discussion of Environmental Tax Reforms which seems to inspire much of the economic thinking about contemporary policies. An outlook for the 21st century concludes the paper.

    The concept of sparse Bayesian learning has received much attention in the machine learning literature as a means of achieving parsimonious representations of features used in regression and classification. It is an important family of algorithms for sparse signal recovery and compressed sensing....... Hence in its current form it is reminiscent of a greedy forward feature selection algorithm.

    Carvalho, Joaquim Francisco de; Mercedes, Sonia Seger P.; Sauer, Ildo L.

    2010-01-01

    In this paper the precautionary principle is reviewed alongside the process of international implementation. Adoption of the precautionary principle is advocated to deal with energy choices as a mechanism to account for potential climate change impacts, notwithstanding the debate on scientific uncertainty on the links between solar activity, greenhouse gas concentration and climate. However, it is also recognized that the widespread application of the precautionary principle to energy choices does not seem to be taking place in the real world. Relevant concrete barriers are identified stemming from the intrinsic logic governing the hegemonic economic system, driving the energy choices by economic surplus and rent generation potential, the existence of social asymmetries inside and among societies as well as by the absence of democratic global governance mechanisms, capable of dealing with climate change issues. Such perception seems to have been reinforced by the outcome of the United Nations Climate Change Conference, held in Copenhagen in December 2009.

This principle is based on cognitive IR perspective (Ingwersen & Järvelin, 2005) and implies that each retrieval model is regarded...... that only the inner disjoint overlap documents between fused models are ranked. The second set of experiments was based on traditional data fusion methods. The experiments involved the 30 TREC 5 topics that contain more than 44 relevant documents. In all tests, the Borda and CombSUM scoring methods were...... the individual models at DCV100. At DCV15, however, the results of polyrepresentative fusion were less predictable.The traditional fusion method based on polyrepresentation principles demonstrates a clear picture of performance at both DCV levels and verifies the polyrepresentation predictions for data fusion...

    1976-01-01

    The treatment of ideal experiments connected with the uncertainty principle is continued. The author analyzes successively measurements of momentum and position, and discusses the common reason why the results in all cases differ from the conventional ones. A similar difference exists for the measurement of field strengths. The interpretation given by Weizsaecker, who tried to interpret Bohr's complementarity principle by introducing a multi-valued logic is analyzed. The treatment of the uncertainty principle ΔE Δt is deferred to a later paper as is the interpretation of the method of variation of constants. Every ideal experiment discussed shows various lower limits for the value of the uncertainty product which limits depend on the experimental arrangement and are always (considerably) larger than h.

    2015-01-01

    The aim of this book is to analyze the all important implications of Heisenberg's Uncertainty Principle for a finite universe with very large mass-energy content such as ours. The earlier and main contributors to the formulation of Quantum Mechanics are briefly reviewed regarding the formulation of Heisenberg's Principle. After discussing “indeterminacy” versus ”uncertainty”, the universal constants of physics are reviewed and Planck's units are given. Next, a novel set of units, Heisenberg–Lemaitre units, are defined in terms of the large finite mass of the universe. With the help of Heisenberg's principle, the time evolution of the finite zero-point energy for the universe is investigated quantitatively. Next, taking advantage of the rigorous solutions of Einstein's cosmological equation for a flat, open and mixed universe of finite mass, the most recent and accurate data on the “age” (to) and the expansion rate (Ho) of the universe and their implications are reconsidered.

    2016-01-01

    In this fundamental book the authors devise a framework that describes the working of the brain as a whole. It presents a comprehensive introduction to the principles of Neural Information Processing as well as recent and authoritative research. The books´ guiding principles are the main purpose of neural activity, namely, to organize behavior to ensure survival, as well as the understanding of the evolutionary genesis of the brain. Among the developed principles and strategies belong self-organization of neural systems, flexibility, the active interpretation of the world by means of construction and prediction as well as their embedding into the world, all of which form the framework of the presented description. Since, in brains, their partial self-organization, the lifelong adaptation and their use of various methods of processing incoming information are all interconnected, the authors have chosen not only neurobiology and evolution theory as a basis for the elaboration of such a framework, but also syst...

    This paper will discuss the importance in recognizing the unique aspects of nuclear power generation in an industry facing deregulation, competitiveness, and commercialization. While exciting times of opportunity are again ahead for the nuclear industry, the excitement has to consider that there are differences between general nuclear and general commerce. These differences are driven by some fundamental principles that impact nuclear reactor operation and examples are given of how these principles must be protected to ensure that nuclear generation can be of continued benefit to the public.

    1995-09-01

    Principles that provide general normative frameworks in bioethics have been criticized since the late 1980s, when several different methods and types of moral philosophy began to be proposed as alternatives or substitutes. Several accounts have emerged in recent years, including: (1) Impartial Rule Theory (supported in this issue by K. Danner Clouser), (2) Casuistry (supported in this issue by Albert Jonsen), and (3) Virtue Ethics (supported in this issue by Edmund D. Pellegrino). Although often presented as rival methods or theories, these approaches are consistent with and should not be considered adversaries of a principle-based account.

    2010-01-01

    Full Text Available The use of microdose pharmacokinetic studies as an essential tool in drug development is still to catch on. While this approach promises potential cost savings and a quantum leap in efficiencies of the drug development process, major hurdles still need to be overcome before the technique becomes commonplace and part of routine practice. Clear regulations in Europe and the USA have had an enabling effect. The lack of enabling provisions for microdosing studies in Indian regulation, despite low risk and manifest relevance for the local drug development industry, is inconsistent with the country′s aspirations to be among the leaders in pharmaceutical research.

    Full Text Available Accounting principles are rules that help producers of financial information to recognize, evaluate, classify and present information. At the same time, they are very general rules, which can be implemented in several ways, generating more accounting treatments. Although the foreign literature presents numerous classifications of the principles in terms of the given research, we will continue to deal with the terms that have the value of accounting principles, their evolution in the Republic of Moldova, but also the influence on keeping the accounting and financial reporting. In the research, we used the method of comparison, analysis, deduction, but also the historical method. The results of the research on accounting principles will contribute to the development of their applicability both for those studying and researching the field of accounting, as well as for those who apply in practice the keeping of accounting in all stages of work: elaboration of accounting policies, recognition, evaluation and accounting for economic transactions and preparing the financial statements of the entity.

  5. Time-advance algorithms based on Hamilton's principle

    International Nuclear Information System (INIS)

    Lewis, H.R.; Kostelec, P.J.

    1993-01-01

    Time-advance algorithms based on Hamilton's variational principle are being developed for application to problems in plasma physics and other areas. Hamilton's principle was applied previously to derive a system of ordinary differential equations in time whose solution provides an approximation to the evolution of a plasma described by the Vlasov-Maxwell equations. However, the variational principle was not used to obtain an algorithm for solving the ordinary differential equations numerically. The present research addresses the numerical solution of systems of ordinary differential equations via Hamilton's principle. The basic idea is first to choose a class of functions for approximating the solution of the ordinary differential equations over a specific time interval. Then the parameters in the approximating function are determined by applying Hamilton's principle exactly within the class of approximating functions. For example, if an approximate solution is desired between time t and time t + Δ t, the class of approximating functions could be polynomials in time up to some degree. The issue of how to choose time-advance algorithms is very important for achieving efficient, physically meaningful computer simulations. The objective is to reliably simulate those characteristics of an evolving system that are scientifically most relevant. Preliminary numerical results are presented, including comparisons with other computational methods

  6. Quantum Mechanics and the Principle of Least Radix Economy

    Science.gov (United States)

    Garcia-Morales, Vladimir

    2015-03-01

    A new variational method, the principle of least radix economy, is formulated. The mathematical and physical relevance of the radix economy, also called digit capacity, is established, showing how physical laws can be derived from this concept in a unified way. The principle reinterprets and generalizes the principle of least action yielding two classes of physical solutions: least action paths and quantum wavefunctions. A new physical foundation of the Hilbert space of quantum mechanics is then accomplished and it is used to derive the Schrödinger and Dirac equations and the breaking of the commutativity of spacetime geometry. The formulation provides an explanation of how determinism and random statistical behavior coexist in spacetime and a framework is developed that allows dynamical processes to be formulated in terms of chains of digits. These methods lead to a new (pre-geometrical) foundation for Lorentz transformations and special relativity. The Parker-Rhodes combinatorial hierarchy is encompassed within our approach and this leads to an estimate of the interaction strength of the electromagnetic and gravitational forces that agrees with the experimental values to an error of less than one thousandth. Finally, it is shown how the principle of least-radix economy naturally gives rise to Boltzmann's principle of classical statistical thermodynamics. A new expression for a general (path-dependent) nonequilibrium entropy is proposed satisfying the Second Law of Thermodynamics.

  14. The Principle of Energetic Consistency

    Science.gov (United States)

    Cohn, Stephen E.

    2009-01-01

    A basic result in estimation theory is that the minimum variance estimate of the dynamical state, given the observations, is the conditional mean estimate. This result holds independently of the specifics of any dynamical or observation nonlinearity or stochasticity, requiring only that the probability density function of the state, conditioned on the observations, has two moments. For nonlinear dynamics that conserve a total energy, this general result implies the principle of energetic consistency: if the dynamical variables are taken to be the natural energy variables, then the sum of the total energy of the conditional mean and the trace of the conditional covariance matrix (the total variance) is constant between observations. Ensemble Kalman filtering methods are designed to approximate the evolution of the conditional mean and covariance matrix. For them the principle of energetic consistency holds independently of ensemble size, even with covariance localization. However, full Kalman filter experiments with advection dynamics have shown that a small amount of numerical dissipation can cause a large, state-dependent loss of total variance, to the detriment of filter performance. The principle of energetic consistency offers a simple way to test whether this spurious loss of variance limits ensemble filter performance in full-blown applications. The classical second-moment closure (third-moment discard) equations also satisfy the principle of energetic consistency, independently of the rank of the conditional covariance matrix. Low-rank approximation of these equations offers an energetically consistent, computationally viable alternative to ensemble filtering. Current formulations of long-window, weak-constraint, four-dimensional variational methods are designed to approximate the conditional mode rather than the conditional mean. Thus they neglect the nonlinear bias term in the second-moment closure equation for the conditional mean. The principle of

    Science.gov (United States)

    Egorova, Ksenia; Antranikian, Garabed

    2005-12-01

    The dramatic increase of newly isolated extremophilic microorganisms, analysis of their genomes and investigations of their enzymes by academic and industrial laboratories demonstrate the great potential of extremophiles in industrial (white) biotechnology. Enzymes derived from extremophiles (extremozymes) are superior to the traditional catalysts because they can perform industrial processes even under harsh conditions, under which conventional proteins are completely denatured. In particular, enzymes from thermophilic and hyperthermophilic Archaea have industrial relevance. Despite intensive investigations, our knowledge of the structure-function relationships of their enzymes is still limited. Information concerning the molecular properties of their enzymes and genes has to be obtained to be able to understand the mechanisms that are responsible for catalytic activity and stability at the boiling point of water.

  19. Study of the reactor relevance of the NET design concept

    International Nuclear Information System (INIS)

    Reynolds, P.; Worraker, W.J.

    1987-08-01

    The objective of the study was to explore the reactor relevance of NET, i.e. whether the technologies and design principles proposed for NET can be directly extrapolated to a demonstration power reactor (DEMO). The main areas of study were those near to the plasma, namely the divertor, first wall and tritium breeding blanket. Other aspects which were investigated were tritium permeation and recovery, reactor maintenance, afterheat and effects of disruptions. The principal results of the study are briefly presented; the details of the work are given in fourteen appendices. These appendices were selected for INIS and indexed separately. The overall conclusion of the study is that the NET design is only partly relevant to the design requirements of a DEMO reactor. (U.K.)

  20. Useful Principles in Plant Excellence Promotion

    International Nuclear Information System (INIS)

    Kavsek, D.; Bozin, B.

    2002-01-01

    This presentation offers a discussion of some principles identified from a review of significant industry events that affected the safety or reliability of a large number of nuclear power plants worldwide. Over the years of operation, a number of events have occurred in nuclear power plants that have involved problems in human performance. A review of these and other significant events has identified recurring weaknesses in plant safety culture and policy and procedure weaknesses. Focusing attention on strengthening relevant processes can help plants avoid similar significant events. Events continue to occur because the lessons learned from industry and plant operating experience are ineffectively used. In some cases, industry events have been communicated to the personnel of the plant in question, but without a thorough explanation of the lessons learned and applicability to the plant. The corrective actions identified have sometimes been limited in scope and have not fully addressed generic issues. The review and implementation of corrective actions for in-house events have sometimes been inadequate to prevent recurrences. An effective operating experience program can significantly reduce the potential for recurring events. The value of learning and applying the knowledge gained from operating experience should be an integral part of plant culture and promoted as an expectation. When operating experience is reviewed, generic issues and causal factors should be explored, rather than focusing on the unique problems that led to a specific event. Lessons learned and applicability to the plant must be clearly identified, corrective action taken, and changes thoroughly communicated to the plant personnel. Their understanding of the changes and the reasons for them should then be confirmed. The following principles will be discussed in this presentation: recognizing conditions during evolutions, promoting teamwork, recognizing fundamental knowledge weaknesses

    2000-01-01

    Pneumatic, hydraulic and allied instrumentation schemes have given way to electronic schemes in recent years thanks to the rapid strides in electronics and allied areas. Principles, design and applications of such state-of-the-art instrumentation schemes form the subject matter of this book. Through representative examples, the basic building blocks of instrumentation schemes are identified and each of these building blocks discussed in terms of its design and interface characteristics. The common generic schemes synthesized with such building blocks are dealt with subsequently. This forms the scope of Part I. The focus in Part II is on application. Displacement and allied instrumentation, force and allied instrumentation and process instrumentation in terms of temperature, flow, pressure level and other common process variables are dealt with separately and exhaustively. Despite the diversity in the sensor principles and characteristics and the variety in the applications and their environments, it is possib...

    2017-01-01

    This book reflects the latest advances in nonlinear optics. Besides the simple, strict mathematical deduction, it also discusses the experimental verification and possible future applications, such as the all-optical switches. It consistently uses the practical unit system throughout. It employs simple physical images, such as "light waves" and "photons" to systematically explain the main principles of nonlinear optical effects. It uses the first-order nonlinear wave equation in frequency domain under the condition of “slowly varying amplitude approximation" and the classical model of the interaction between the light and electric dipole. At the same time, it also uses the rate equations based on the energy-level transition of particle systems excited by photons and the energy and momentum conservation principles to explain the nonlinear optical phenomenon. The book is intended for researchers, engineers and graduate students in the field of the optics, optoelectronics, fiber communication, information tech...

  3. Track formation. Principles and applications

    Monnin, M.

    1978-01-01

    The principles and technical aspects of track formation in insulating solids are first described. The characteristics of dialectic track detection are discussed from the technical point of view: the nature of the detectors, the chemical treatment, the sensitivity and the environmental conditions of use. The applications are reviewed. The principle of each type of applied research is described and then the applications are listed. When used as a detector, nuclear tracks can provide valuable information in a number of fields: element content determination and wrapping, imaging, radiation dosimetry, environmental studies, technological uses and miscellaneous other applications. The track-formation process can also be used for making well-defined holes; this method allows other applications which are also described. Finally, some possible future applications are mentioned.

  4. On a generalized bootstrap principle

    Corrigan, E.; Sasaki, R.; Dorey, P.E.

    1993-01-01

    The S-matrices for non-simply-laced affine Toda field theories are considered in the context of a generalized bootstrap principle. The S-matrices, and in particular their poles, depend on a parameter whose range lies between the Coxeter numbers of dual pairs of the corresponding non-simply-laced algebras. It is proposed that only odd order poles in the physical strip with positive coefficients throughout this range should participate in the bootstrap. All other singularities have an explanation in principle in terms of a generalized Coleman-Thun mechanism. Besides the S-matrices introduced by Delius, Grisaru and Zanon, the missing case (F 4 (1) , e 6 (2) ), is also considered and provides many interesting examples of pole generation. (author)

    Thaller, L. H.

    1986-01-01

    The higher power and higher voltage levels anticipated for future space missions have required a careful review of the techniques currently in use to preclude battery problems that are related to the dispersion characteristics of the individual cells. Not only are the out-of-balance problems accentuated in these larger systems, but the thermal management considerations also require a greater degree of accurate design. Newer concepts which employ active cooling techniques are being developed which permit higher rates of discharge and tighter packing densities for the electrochemical components. This paper will put forward six semi-independent principles relating to battery systems. These principles will progressively address cell, battery and finally system related aspects of large electrochemical storage systems.

  6. Ultima Ratio as a Constitutional Principle

    Directory of Open Access Journals (Sweden)

    Kaarlo Tuori

    2013-01-01

    Full Text Available The paper argues the criminal law notion of ultima ratio is an instance of a broader constitutional law principle of proportionality. However, ultima ratio is not the only principle relevant in a constitutional assessment of criminalization. The role of ultima ratio is to impose limitations on criminalization. But constitutional doctrines also exist which call for criminalization and might even be seen as establishing a criminalization obligation. The paper examines three constitutional counter weights to ultima ratio. The first of these is discussed in the context of state constitutions. This is the cluster of the interrelated constitutional doctrines of the horizontal effect of fundamental rights and the protective duty of the state, as well as the understanding of collective security as a basic right. These doctrines are analysed in the light of the praxis of the German Constitutional Court and the Finnish Constitutional Law Committee. The two other constitutional counterweights are discussed at the level of the transnational, European constitution. These are the principles of precaution and effectiveness. Este artículo defiende que el concepto de ultima ratio es una instancia más amplia del principio de proporcionalidad dentro del derecho constitucional. Sin embargo, el ultima ratio no es el único principio relevante en la valoración constitucional de la criminalización. El papel del ultima ratio es imponer límites a la criminalización. Pero también existen doctrinas constitucionales que exigen la criminalización e incluso dan pie a entender que obligan a establecer una pena. El documento examina tres contrapesos constitucionales al ultima ratio. En primer lugar, se analiza en el contexto de las constituciones estatales. Este es el conjunto de las doctrinas constitucionales interrelacionadas entre el efecto horizontal de los derechos fundamentales y el deber de protección del Estado, así como la asunción de la seguridad colectiva

  18. Cognitive Principles in Metonymic Headlines

    Directory of Open Access Journals (Sweden)

    Elena S. Milkevich

    2017-06-01

    Full Text Available The article focuses on metonymy as a linguistic device. Traditionally metonymy is considered within the domain of stylistics. However, methods of cognitive linguistics help to penetrate into the essence of language phenomena and explain their nature as part f more general process of human cognition. Cognitive linguistics puts forward the hypothesis that the use of metonymy is governed by cognitive principles. They are based on our experience, perception and culture. The article presents a study of metonymy in political headlines and analyses the application of cognitive principles to metonymy. We analyse the cases of metonymy presented by proper nouns geographical names such as names of countries, capital, continents. We come to the conclusion that the concept «COUNTRY» is the metonymic vehicle in three types of models: most frequent types of metonymy are: «COUNTRY FOR ITS GOVERNMENT», «COUNTRY FOR EVENT» and «COUNTRY FOR ACTION». The concept «COUNTRY» can also be the target in metonymy types «CAPITAL FOR COUNTRY» and «CONTINENT FOR COUNTRIES». The leading cognitive principles in such types of metonymic relationships are: based on human experience «CONCRETE OVER ABSTRACT», «INERACTIONAL OVER NON-INTERACTIONAL»; based on perceptual selectivity «DOMINANT OVER LESS DOMINANT», «MORE OVER LESS»; based on cultural preference «CENTRAL OVER PERIPHERAL», «MORE IMPORTANT OVER LESS IMPORTANT».

  19. The balance principle in scientific research.

    Hu, Liang-ping; Bao, Xiao-lei; Wang, Qi

    2012-05-01

    The principles of balance, randomization, control and repetition, which are closely related, constitute the four principles of scientific research. The balance principle is the kernel of the four principles which runs through the other three. However, in scientific research, the balance principle is always overlooked. If the balance principle is not well performed, the research conclusion is easy to be denied, which may lead to the failure of the whole research. Therefore, it is essential to have a good command of the balance principle in scientific research. This article stresses the definition and function of the balance principle, the strategies and detailed measures to improve balance in scientific research, and the analysis of the common mistakes involving the use of the balance principle in scientific research.

  20. Vygotsky's Crisis: Argument, context, relevance.

    Hyman, Ludmila

    2012-06-01

    Vygotsky's The Historical Significance of the Crisis in Psychology (1926-1927) is an important text in the history and philosophy of psychology that has only become available to scholars in 1982 in Russian, and in 1997 in English. The goal of this paper is to introduce Vygotsky's conception of psychology to a wider audience. I argue that Vygotsky's argument about the "crisis" in psychology and its resolution can be fully understood only in the context of his social and political thinking. Vygotsky shared the enthusiasm, widespread among Russian leftist intelligentsia in the 1920s, that Soviet society had launched an unprecedented social experiment: The socialist revolution opened the way for establishing social conditions that would let the individual flourish. For Vygotsky, this meant that "a new man" of the future would become "the first and only species in biology that would create itself." He envisioned psychology as a science that would serve this humanist teleology. I propose that The Crisis is relevant today insofar as it helps us define a fundamental problem: How can we systematically account for the development of knowledge in psychology? I evaluate how Vygotsky addresses this problem as a historian of the crisis. Copyright © 2011 Elsevier Ltd. All rights reserved.

  1. Relevance of equilibrium in multifragmentation

    International Nuclear Information System (INIS)

    Furuta, Takuya; Ono, Akira

    2009-01-01

    The relevance of equilibrium in a multifragmentation reaction of very central 40 Ca + 40 Ca collisions at 35 MeV/nucleon is investigated by using simulations of antisymmetrized molecular dynamics (AMD). Two types of ensembles are compared. One is the reaction ensemble of the states at each reaction time t in collision events simulated by AMD, and the other is the equilibrium ensemble prepared by solving the AMD equation of motion for a many-nucleon system confined in a container for a long time. The comparison of the ensembles is performed for the fragment charge distribution and the excitation energies. Our calculations show that there exists an equilibrium ensemble that well reproduces the reaction ensemble at each reaction time t for the investigated period 80≤t≤300 fm/c. However, there are some other observables that show discrepancies between the reaction and equilibrium ensembles. These may be interpreted as dynamical effects in the reaction. The usual static equilibrium at each instant is not realized since any equilibrium ensemble with the same volume as that of the reaction system cannot reproduce the fragment observables

  3. Principles of parametric estimation in modeling language competition.

    Science.gov (United States)

    Zhang, Menghan; Gong, Tao

    2013-06-11

    It is generally difficult to define reasonable parameters and interpret their values in mathematical models of social phenomena. Rather than directly fitting abstract parameters against empirical data, we should define some concrete parameters to denote the sociocultural factors relevant for particular phenomena, and compute the values of these parameters based upon the corresponding empirical data. Taking the example of modeling studies of language competition, we propose a language diffusion principle and two language inheritance principles to compute two critical parameters, namely the impacts and inheritance rates of competing languages, in our language competition model derived from the Lotka-Volterra competition model in evolutionary biology. These principles assign explicit sociolinguistic meanings to those parameters and calculate their values from the relevant data of population censuses and language surveys. Using four examples of language competition, we illustrate that our language competition model with thus-estimated parameter values can reliably replicate and predict the dynamics of language competition, and it is especially useful in cases lacking direct competition data.

    2017-04-01

    In March this year, the American Statistical Association (ASA) posted a statement on the correct use of P-values, in response to a growing concern that the P-value is commonly misused and misinterpreted. We aim to translate these warnings given by the ASA into a language more easily understood by clinicians and researchers without a deep background in statistics. Moreover, we intend to illustrate the limitations of P-values, even when used and interpreted correctly, and bring more attention to the clinical relevance of study findings using two recently reported studies as examples. We argue that P-values are often misinterpreted. A common mistake is saying that P < 0.05 means that the null hypothesis is false, and P ≥0.05 means that the null hypothesis is true. The correct interpretation of a P-value of 0.05 is that if the null hypothesis were indeed true, a similar or more extreme result would occur 5% of the times upon repeating the study in a similar sample. In other words, the P-value informs about the likelihood of the data given the null hypothesis and not the other way around. A possible alternative related to the P-value is the confidence interval (CI). It provides more information on the magnitude of an effect and the imprecision with which that effect was estimated. However, there is no magic bullet to replace P-values and stop erroneous interpretation of scientific results. Scientists and readers alike should make themselves familiar with the correct, nuanced interpretation of statistical tests, P-values and CIs. © The Author 2017.

    2012-02-01

    In order to understand the consequences of radiation a thorough understanding of the radiobiological mechanisms of the molecular up to the clinical level is of importance. Radiobiology therefore combines the basic principles of physics as well as biology and medicine and is concerned with the action of radiation from the subcellular level up to the living organism. Topics of interest and relevance are covered in much more broadness as is possible in the short following article in the literature to which the interested reader is referred to. Classical books in this field were written by Steel et al. (1989) as well as by Hall (1994). Topics usually covered by radiobiological reviews are the classification of different types of radiation, cell cycle dependency of radiation effects, types of radiation damage and cell death, dose response curves, measurement of radiation damage, the oxygen effect, relative biological effectiveness, the influence of dose rate, and several other important research areas. This short overview will concentrate on a subset of radiobiological topics of high importance and relative novelty.

    2014-01-01

    Obesity, is a chronic, biological, preventable, and treatable disease. The accumulation of fat mass causes physical changes (adiposity), metabolic and hormonal changes due to adipose tissue dysfunction (adiposopathy), and psychological changes. Bariatric endocrinology was conceived from the need to address the neuro-endocrinological derangements that are associated with adiposopathy, and from the need to broaden the scope of the management of its complications. In addition to the well-established metabolic complications of overweight and obesity, adiposopathy leads to hyperinsulinemia, hyperleptinemia, hypoadiponectinemia, dysregulation of gut peptides including GLP-1 and ghrelin, the development of an inflammatory milieu, and the strong risk of vascular disease. Therapy for adiposopathy hinges on effectively lowering the ratio of orexigenic to anorexigenic signals reaching the the hypothalamus and other relevant brain regions, favoring a lower caloric intake. Adiposopathy, overweight and obesity should be treated indefinitely with the specific aims to reduce fat mass for the adiposity complications, and to normalize adipose tissue function for the adiposopathic complications. This paper defines the principles of medical practice in bariatric endocrinology—the treatment of overweight and obesity as means to treat adiposopathy and its accompanying metabolic and hormonal derangements.

  11. The principle of finiteness – a guideline for physical laws

    International Nuclear Information System (INIS)

    Sternlieb, Abraham

    2013-01-01

    I propose a new principle in physics-the principle of finiteness (FP). It stems from the definition of physics as a science that deals with measurable dimensional physical quantities. Since measurement results including their errors, are always finite, FP postulates that the mathematical formulation of legitimate laws in physics should prevent exactly zero or infinite solutions. I propose finiteness as a postulate, as opposed to a statement whose validity has to be corroborated by, or derived theoretically or experimentally from other facts, theories or principles. Some consequences of FP are discussed, first in general, and then more specifically in the fields of special relativity, quantum mechanics, and quantum gravity. The corrected Lorentz transformations include an additional translation term depending on the minimum length epsilon. The relativistic gamma is replaced by a corrected gamma, that is finite for v=c. To comply with FP, physical laws should include the relevant extremum finite values in their mathematical formulation. An important prediction of FP is that there is a maximum attainable relativistic mass/energy which is the same for all subatomic particles, meaning that there is a maximum theoretical value for cosmic rays energy. The Generalized Uncertainty Principle required by Quantum Gravity is actually a necessary consequence of FP at Planck's scale. Therefore, FP may possibly contribute to the axiomatic foundation of Quantum Gravity.

The original Maupertuis (Euler-Lagrange) principle constrains the energy at every point along the trajectory. The generalized Maupertuis principle is equivalent to Hamilton's principle. Reciprocal principles are also derived for both the generalized Maupertuis and the Hamilton principles. The reciprocal Maupertuis principle is the classical limit of Schroedinger's variational principle of wave mechanics and is also very useful to solve practical problems in both classical and semiclassical mechanics, in complete analogy with the quantum Rayleigh-Ritz method. Classical, semiclassical and quantum variational calculations are carried out for a number of systems, and the results are compared. Pedagogical as well as research problems are used as examples, which include nonconservative as well as relativistic systems. '... the most beautiful and important discovery of Mechanics.'

    The four principles of Beauchamp and Childress--autonomy, non-maleficence, beneficence and justice--have been extremely influential in the field of medical ethics, and are fundamental for understanding the current approach to ethical assessment in health care. This study tests whether these principles can be quantitatively measured on an individual level, and then subsequently if they are used in the decision making process when individuals are faced with ethical dilemmas. The Analytic Hierarchy Process was used as a tool for the measurement of the principles. Four scenarios, which involved conflicts between the medical ethical principles, were presented to participants who then made judgments about the ethicality of the action in the scenario, and their intentions to act in the same manner if they were in the situation. Individual preferences for these medical ethical principles can be measured using the Analytic Hierarchy Process. This technique provides a useful tool in which to highlight individual medical ethical values. On average, individuals have a significant preference for non-maleficence over the other principles, however, and perhaps counter-intuitively, this preference does not seem to relate to applied ethical judgements in specific ethical dilemmas. People state they value these medical ethical principles but they do not actually seem to use them directly in the decision making process. The reasons for this are explained through the lack of a behavioural model to account for the relevant situational factors not captured by the principles. The limitations of the principles in predicting ethical decision making are discussed.

  17. Rotating detectors and Mach's principle

    2000-08-01

    In this work we consider a quantum version of Newton s bucket experiment in a fl;at spacetime: we take an Unruh-DeWitt detector in interaction with a real massless scalar field. We calculate the detector's excitation rate when it is uniformly rotating around some fixed point and the field is prepared in the Minkowski vacuum and also when the detector is inertial and the field is in the Trocheries-Takeno vacuum state. These results are compared and the relations with Mach's principle are discussed. (author)

    Ethnography is a methodology that is gaining popularity in nursing and healthcare research. It is concerned with studying people in their cultural context and how their behaviour, either as individuals or as part of a group, is influenced by this cultural context. Ethnography is a form of social research and has much in common with other forms of qualitative enquiry. While classical ethnography was characteristically concerned with describing 'other' cultures, contemporary ethnography has focused on settings nearer to home. This article outlines some of the underlying principles and practice of ethnography, and its potential for nursing and healthcare practice.

    This article analyses the decision-making process underlying the adoption of common EU flexicurity principles. Supporters of the initiative succeeded in convincing the sceptics one by one; the change of government in France and the last-minute support of the European social partner organizations...... were instrumental in this regard. However, the critics succeeded in weakening the initially strong focus on the transition from job security to employment security and the divisions between insiders and outsiders in the labour market. In contrast to some decision-making on the European Employment...

  8. Variational principle in quantum mechanics

    International Nuclear Information System (INIS)

    Popiez, L.

    1986-01-01

    The variational principle in a standard, path integral formulation of quantum mechanics (as proposed by Dirac and Feynman) appears only in the context of a classical limit n to 0 and manifests itself through the method of abstract stationary phase. Symbolically it means that a probability amplitude averaged over trajectories denotes a classical evolution operator for points in a configuration space. There exists, however, the formulation of quantum dynamics in which variational priniple is one of basic postulates. It is explained that the translation between stochastic and quantum mechanics in this case can be understood as in Nelson's stochastic mechanics

  10. Principle of accelerator mass spectrometry

    International Nuclear Information System (INIS)

    Matsuzaki, Hiroyuki

    2007-01-01

    The principle of accelerator mass spectrometry (AMS) is described mainly on technical aspects: hardware construction of AMS, measurement of isotope ratio, sensitivity of measurement (measuring limit), measuring accuracy, and application of data. The content may be summarized as follows: rare isotope (often long-lived radioactive isotope) can be detected by various use of the ion energy obtained by the acceleration of ions, a measurable isotope ratio is one of rare isotope to abundant isotopes, and a measured value of isotope ratio is uncertainty to true one. Such a fact must be kept in mind on the use of AMS data to application research. (M.H.)

    Science.gov (United States)

    Chan, Heidi P; Zhai, Hongbo; Hui, Xiaoying; Maibach, Howard I

    2013-11-01

    Skin decontamination is the primary intervention needed in chemical, biological and radiological exposures, involving immediate removal of the contaminant from the skin performed in the most efficient way. The most readily available decontamination system on a practical basis is washing with soap and water or water only. Timely use of flushing with copious amounts of water may physically remove the contaminant. However, this traditional method may not be completely effective, and contaminants left on the skin after traditional washing procedures can have toxic consequences. This article focuses on the principles and practices of skin decontamination.

  13. Reciprocity principle in duct acoustics

    Science.gov (United States)

    Cho, Y.-C.

    1979-01-01

    Various reciprocity relations in duct acoustics have been derived on the basis of the spatial reciprocity principle implied in Green's functions for linear waves. The derivation includes the reciprocity relations between mode conversion coefficients for reflection and transmission in nonuniform ducts, and the relation between the radiation of a mode from an arbitrarily terminated duct and the absorption of an externally incident plane wave by the duct. Such relations are well defined as long as the systems remain linear, regardless of acoustic properties of duct nonuniformities which cause the mode conversions.

    2007-01-01

    A major objective of this book is to fill the gap between traditional logic design principles and logic design/optimization techniques used in practice. Over the last two decades several techniques for computer-aided design and optimization of logic circuits have been developed. However, underlying theories of these techniques are inadequately covered or not covered at all in undergraduate text books. This book covers not only the ""classical"" material found in current text books but also selected materials that modern logic designers need to be familiar with.

    Up to the amendment of the Energy Economy Law (EnWG) 2005 the legislator permitted parallel applicability of the Energy Economy law as well as the Restriction of Competition (GWB) to energy situations. Based on the GWB, especially in procedures by competition authorities key decisions on the reliable behaviour of operators of power distribution systems and natural gas distribution systems were disposed. This approach was restricted by the amendment of the EnWG 2005 with the introduction of paragraph 111 EnWG. In compliance with this, this restriction was implemented in paragraph 130 sect. 3 GWB. From now on, paragraph 111 Sect. 1 and 2 EnWG exclude the antitrust control of abuse according to the paragraphs 19, 20 and 29 GWB. With this, the competence of the cartel authorities are excluded in favour of the regulatory legal prescriptions of the EnWG.
