  1. The Relevance of Causal Social Construction

    2017-02-01

    Full Text Available Social constructionist claims are surprising and interesting when they entail that presumably natural kinds are in fact socially constructed. The claims are interesting because of their theoretical and political importance. Authors like Díaz-León argue that constitutive social construction is more relevant for achieving social justice than causal social construction. This paper challenges this claim. Assuming there are socially salient groups that are discriminated against, the paper presents a dilemma: if there were no constitutively constructed social kinds, the causes of the discrimination of existing social groups would have to be addressed, and understanding causal social construction would be relevant to achieve social justice. On the other hand, not all possible constitutively socially constructed kinds are actual social kinds. If an existing social group is constitutively constructed as a social kind K, the fact that it actually exists as a K has social causes. Again, causal social construction is relevant. The paper argues that (i for any actual social kind X, if X is constitutively socially constructed as K, then it is also causally socially constructed; and (ii causal social construction is at least as relevant as constitutive social construction for concerns of social justice. For illustration, I draw upon two phenomena that are presumed to contribute towards the discrimination of women: (i the poor performance effects of stereotype threat, and (ii the silencing effects of gendered language use.

    Full Text Available This research integrates systemic and participatory techniques to model the Russian Federation construction innovation system. Understanding this complex construction innovation system and determining the best levers for enhancing it require the dynamic modelling of a number of factors, such as flows of resources and activities, policies, uncertainty and time. To build the foundations for such a dynamic model, the employed study method utilised an integrated stakeholder-based participatory approach coupled with structural analysis (MICMAC—Matrice d'Impacts Croisés Multiplication Appliquée à un Classement Cross-Impact Matrix. This method identified the key factors of the Russian Federation construction innovation system, their causal relationship (i.e., influence/dependence map and, ultimately, a causal loop diagram. The generated model reveals pathways to improving construction innovation in the Russian Federation and underpins the future development of an operationalised system dynamics model.

    Full Text Available This study empirically investigates the causal relationship between construction production and GDP for Turkey during 2005Q1-2013Q4 period. Because it is found that, there is no cointegration which means there is no long run relationship between variables, VAR Granger Causality Method is used to test the causality in short run. The findings reveal that, the causality runs from GDP to Building Production and Building Production to Non-Building Production (i.e. bidirectional relationship. Findings of this paper suggest that, because there is no long run relationship between Construction Production (Building and Non-Building and GDP and also in short run the causality runs from GDP to Construction Production, the growth strategy based on mainly Construction Sector growth is not a good idea for Turkey.

    2009-01-01

    Full Text Available Russian psychology has brought into the world science at least two great ideas: the conditioned reflex (Pavlov and the zone of proximal development (Vygotsky. These concepts were formulated before “iron curtain” fell. Since then Russian science dropped out from the view of western colleagues for decades. Now it is challenged to re-join international mainstream. Are we in a position to contribute?A key concept for Russian psychology is personality impact on psycho-physiological functions and causal approach to self-determination. The concept of selfdetermination appeared in Western theories in 1980-es and since then it has been developed in the context of teleological humanitarian approach. In Russian science the concept of self-determination dates back to 1934, when it was defined by Rubinstein as “sub’ekt”. Self-determination of ontogenesis of psycho physiological functions resulting from confluence of ontogenesis and social development was explicated by Russian scientists whose theoretical reasoning and empirical results are compared to Western counterparts.

  6. Causality in Psychiatry: A Hybrid Symptom Network Construct Model

    Directory of Open Access Journals (Sweden)

    Gerald eYoung

    2015-11-01

    Full Text Available Causality or etiology in psychiatry is marked by standard biomedical, reductionistic models (symptoms reflect the construct involved that inform approaches to nosology, or classification, such as in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; American Psychiatric Association, 2013. However, network approaches to symptom interaction (i.e., symptoms are formative of the construct; e.g., McNally, Robinaugh, Wu, Wang, Deserno, & Borsboom, 2014, for PTSD (posttraumatic stress disorder are being developed that speak to bottom-up processes in mental disorder, in contrast to the typical top-down psychological construct approach. The present article presents a hybrid top-down, bottom-up model of the relationship between symptoms and mental disorder, viewing symptom expression and their causal complex as a reciprocally dynamic system with multiple levels, from lower-order symptoms in interaction to higher-order constructs affecting them. The hybrid model hinges on good understanding of systems theory in which it is embedded, so that the article reviews in depth nonlinear dynamical systems theory (NLDST. The article applies the concept of emergent circular causality (Young, 2011 to symptom development, as well. Conclusions consider that symptoms vary over several dimensions, including: subjectivity; objectivity; conscious motivation effort; and unconscious influences, and the degree to which individual (e.g., meaning and universal (e.g., causal processes are involved. The opposition between science and skepticism is a complex one that the article addresses in final comments.

  8. Construction of the migration flows forecasting into Russian regions

    Directory of Open Access Journals (Sweden)

    Aleksandr Aleksandrovich Tarasyev

    2013-06-01

    Full Text Available This paper presents a dynamic model that can predict the dynamics of migration flows between source countries and host regions, as well as the dynamics of wage levels there. The model is constructed within the framework of neoclassical economics and human capital theory in continuous time. Thanks to liberalization of migration policy in Russia in 2007, the model could be successfully employed to Russian regions and the Commonwealth of Independent States (CIS, which have visa-free entry regulations with the Russian Federation. Employing the model on statistical data, we forecast the number and origin composition of foreign labor force from the CIS into Russian regions for 2010-2016. The purpose of our further research is to classify migrants by skills

    The development of efficient and strategic anti-corruption measures can be better achieved if a deeper understanding and identification of the causes of corruption are established. Over the past years, many studies have been devoted to the research of corruption in construction management (CM). This has resulted in a significant increase in the body of knowledge on the subject matter, including the causative factors triggering these corrupt practices. However, an apropos systematic assessment of both past and current studies on the subject matter which is needful for the future endeavor is lacking. Moreover, there is an absence of unified view of the causative factors of corruption identified in construction project management (CPM). This paper, therefore, presents a comprehensive review of the causes of corruption from selected articles in recognized construction management journals to address the mentioned gaps. A total number of 44 causes of corruption were identified from 37 publications and analyzed in terms of existing causal factors of corruption, annual trend of publications and the thematic categorization of the identified variables. The most identifiable causes were over close relationships, poor professional ethical standards, negative industrial and working conditions, negative role models and inadequate sanctions. A conceptual framework of causes of corruption was established, after categorizing the 44 variables into five unique categories. In descending order, the five constructs are Psychosocial-Specific Causes, Organizational-Specific Causes, Regulatory-Specific Causes, Project-Specific Causes and Statutory-Specific Causes. This study extends the current literature of corruption research in construction management and contributes to a deepened understanding of the causal instigators of corruption identified in CPM. The findings from this study provide valuable information and extended knowledge to industry practitioners and policymakers as well as

  10. Investigating the multi-causal and complex nature of the accident causal influence of construction project features.

    Manu, Patrick A; Ankrah, Nii A; Proverbs, David G; Suresh, Subashini

    2012-09-01

    Construction project features (CPFs) are organisational, physical and operational attributes that characterise construction projects. Although previous studies have examined the accident causal influence of CPFs, the multi-causal attribute of this causal phenomenon still remain elusive and thus requires further investigation. Aiming to shed light on this facet of the accident causal phenomenon of CPFs, this study examines relevant literature and crystallises the attained insight of the multi-causal attribute by a graphical model which is subsequently operationalised by a derived mathematical risk expression that offers a systematic approach for evaluating the potential of CPFs to cause harm and consequently their health and safety (H&S) risk implications. The graphical model and the risk expression put forth by the study thus advance current understanding of the accident causal phenomenon of CPFs and they present an opportunity for project participants to manage the H&S risk associated with CPFs from the early stages of project procurement.

  11. Causality

    Science.gov (United States)

    Pearl, Judea

    2000-03-01

    Written by one of the pre-eminent researchers in the field, this book provides a comprehensive exposition of modern analysis of causation. It shows how causality has grown from a nebulous concept into a mathematical theory with significant applications in the fields of statistics, artificial intelligence, philosophy, cognitive science, and the health and social sciences. Pearl presents a unified account of the probabilistic, manipulative, counterfactual and structural approaches to causation, and devises simple mathematical tools for analyzing the relationships between causal connections, statistical associations, actions and observations. The book will open the way for including causal analysis in the standard curriculum of statistics, artifical intelligence, business, epidemiology, social science and economics. Students in these areas will find natural models, simple identification procedures, and precise mathematical definitions of causal concepts that traditional texts have tended to evade or make unduly complicated. This book will be of interest to professionals and students in a wide variety of fields. Anyone who wishes to elucidate meaningful relationships from data, predict effects of actions and policies, assess explanations of reported events, or form theories of causal understanding and causal speech will find this book stimulating and invaluable.

  13. Accident Causal Factors on the Building Construction Sites: A Review

    Directory of Open Access Journals (Sweden)

    Opeyemi Samuel Williams

    2018-01-01

    Full Text Available The concerns for cost, quality and timely delivery of projects have been in existence from time immemorial, whereas the passion for these should be extended to safe execution of site works by the construction participants, as safety of life is very paramount. However, high level of commitment that is essential for the safe execution of site works has become a taboo. Hence, a plethora of accidents takes place on the site ranging from falls from height, contact with working tools, vehicle-related, slip and trip, collapse, exposure to harmful substances, to lifting and handling object accidents. It is pertinent to know that, responsibility for accidents on site cuts across all project participants (clients, consultants, contractors, workers, as well as the construction site environment. Recognition of the construction participants and site environmental factors as agents of accident is the focus of this research. Through extensive review of literature, a copious number of factors were identified and subsequently grouped under five factors as client-related, consultant-related, contractor-related, construction workers-related, and construction site-related. However, there has been a dearth of research in the grouping of accident contributing factors. The identification and understanding of these factors will go a long way in mitigating construction accidents, coupled with proven measures taken in positively addressing them. Efforts to prevent these causative factors include inter alia elimination of hazards from design, effective safety management, adequate planning of activities and employment of seasoned professionals by the client. The contractors are to embark on staff safety auditing, set up safety committees, conduct regular training for staff, use innovative technology, uphold housekeeping and report accident occurrence, while strict adherence to safety regulations must be adopted by all construction operatives.

    2013-03-01

    Full Text Available Stepladders are frequently utilized on construction projects as a means of access to elevation. Stepladder heights commonly range from 4 feet (1.2 m to 14 feet (4.3 m. Since these heights are not extreme, there is a common misperception that stepladder use presents a low risk. On the contrary, extreme care must be exercised to ensure that work on stepladders is performed safely, as described in the conspicuously located recommendations and brightly-colored warnings that adorn virtually all newly-purchased equipment. Despite this, accidents involving stepladders occur on a regular basis.  This study was conducted to better understand the underlying causes of these accidents. The narrative descriptions of 180 stepladder-related fatalities were obtained from the U.S. Occupational Safety and Health Administration and were analyzed to identify the at-risk behaviors that preceded the fatality incidents. The results showed that most of the incidents should have been anticipated and could have been avoided. Unsafe practices such as improper lockout-tagout of electrical equipment, loss of balance, working on a folded stepladder, over-reaching, straddling the ladder, “walking” the ladder, poor footing, and unstable/shifting ladders, among others were identified. Virtually all of these fatalities could have been avoided by adhering to the guidelines posted on the stepladders and by complying with basic safe construction practices.

    2018-03-01

    The article considers the economic aspects of constructing high-rise buildings in the world and in Russia. Data on the number of high-rise buildings in Russian cities with a million population are presented. It is proved that interest in high-rise construction in Russia has been formed only in Moscow and partly in St. Petersburg and Yekaterinburg. The analysis showed that the reason for this is the expensiveness of high-rise construction. According to the enlarged macro-calculation, the cost of building 1 m2 of the area of the Federation Towers complex (Moscow City) is about 2710 /m2. Practically a possibility of return on investments in the foreseeable time interval exists only in Moscow. For the regions of Russia this task is rather complicated. Population density in regional Russian cities is quite low, business entities do not have the necessary financial resources for investing in high-rise construction, and investments from abroad absent.

    Full Text Available In this paper we estimate changes of Russian higher education, aimed to incorporate In this paper we estimate changes of Russian higher education, aimed to incorporate the latter in the Bologna process. The analysis of the reforms is given in terms of need in training specialists of the construction industry. The article analyzes the conclusions reached on the issue by some teachers of Russian universities of civil engineering. Among the reasons for concern from the part of the Russian education community, it is called the low level of knowledge about the tasks of re-forms and lack of information regarding measures to improve the educa-tion system. The investigation, in particular, points out that today the main issue of reforming is seen in creation of a single European intellectual space. At the same time, the questionnaire showed that the achievement of the stated purpose is prevented by the following factors: low level of stu-dent-builders in foreign languages and insufficient income. These circums-tances make education abroad almost impossible for most students from Russia and reduce the competitiveness of graduates from Russian universi-ties in labor market of the countries that joined to the Bologna system. The authors of the article pay special attention to the needs of executives of construction firms in qualified specialists. Most of the experts note the iso-lation of universities from solving problems of building practice, a notice-able lag of the national educational system from the western ones in train-ing specialists in construction logistics and organization of construction sites.

    The article describes the concept and types of administrative barriers encountered in various areas of the enterprise. The particularities of the Russian high-rise construction industry are described and a comparative analysis of administrative barriers in this sector is performed. The main stages and administrative procedures when the developers implement investment and construction projects in the field of high-rise construction are determined. The regulatory and legal framework for the implementation of investment and project activities in the high-rise construction industry has been studied and conclusions have been drawn on its low level of precision in the issue of the formation of competitive and efficient high-rise construction markets. The average number of administrative procedures for the implementation of the investment and construction project in the field of high-rise construction is determined. The factors preventing the reduction of administrative barriers in the high-rise construction industry are revealed.

    While there is general agreement regarding poor performance of children with Specific Language Impairment (SLI) on microstructure measures of narrative production, findings on macrostructure are inconsistent. The present study analyzed narrative abilities of Russian-Hebrew bilingual preschool children with and without SLI, with a particular focus on story grammar (SG) elements and causal relations, in order to identify macrostructure features which distinguish bilingual children with SLI from those with typical development. Narratives were collected from 35 typically developing bilinguals (BiTD) and 14 bilinguals with SLI (BiSLI) in both Russian/L1 and Hebrew/L2 using a retelling procedure (LITMUS-Multilingual Assessment Instrument for Narratives) (Gagarina, Klop, Kunnari, Tantele, Välimaa, Balčiūnienė, Bohnacker, & Walters, 2012). Each story contained three episodes, and each episode introduced a different protagonist with explicitly stated Goals (G), Attempts (A) and Outcomes (O). Causal relations assessed included Enabling, Physical, Motivational, and Psychological relations, following Trabasso & Nickels (1992). Each Goal-Attempt-Outcome (GAO) episode was examined for the use of SG elements and causal relations. Group differences emerged for both aspects of macrostructure. For causal relations, narratives of BiSLI children contained fewer Enabling and Physical relations, and differed qualitatively from those of BiTD children. For SG elements, BiSLI children referred to fewer SG elements than BiTD children in the first episode, but performed like BiTD children in the second and the third episodes. Story grammar elements in specific episodes along with Enabling and Physical causal relations distinguish the narratives of children with BiSLI from those with BiTD, which stresses the importance of examining wider array of macrostructure features in narratives.

    The propose of academic affairs is discovery the principal areas of concern high-rise construction in Russia. Examples of modern Russian and foreign high-rise construction are considered in the work. The most important problems and their solutions for Russia are identified on their basis. The everyone area of concern is considered separately. Ecology problems and influence of high-rise construction for the healthy and psychological effect of people are considered special. High-rise constructions influence negative and positive for urban environment in Moscow and Samara cities. The experience lack, defects in requirements document, which don't include all high-rise constructions specific, system problem of construction and often non-availability of proper control at the existing requirements document result for complexity of designing, construction and operation. At this moment, high-rise constructions temp is increasing in Moscow. Feasibility of high-rise buildings come up in regions of Russia. The reasons include high material inputs, irregularities of requirements network and utility lines and maintenance problems. The researching follow up of conclusions and recommendations for high-rise constructions development in Russia. The reasons of high-rise buildings are urbanization of people and necessary of concentration labor supply. The important tasks for organization are creating compact urban environment, decrease urban area for development, using an innovative technology for construction and properly maintenance. The balance between the preference of high-rise construction, inputs for construction and influence for ecology are resolve for this task.

    Full Text Available Focusing on discourses by the ruling elite, this article examines the construction of ‘geopolitical spaces’ in Russian foreign policy. Based on a critical geopolitical analysis, suggesting that territory, space and geographies are being actively (reformulated by those in power, this article analyzes how policy-makers define and articulate the importance of a particular geographical region for their foreign policy. It analyzes how the three ‘geopolitical spaces’ – Eurasia, the Euro-Atlantic and the Asia-Pacific – are defined by Russia's political leaders and how each space fulfils a particular function for the pursuit of Russian interests abroad. In a second part, this article takes into account the events in and around Ukraine starting in late 2013 and analyzes how Russia's discourse toward the traditional ‘geopolitical spaces’ changed as a result. It is argued, that while Russia previously strived for membership in each of the three ‘geopolitical spaces’, the Ukraine crisis and its impact on Moscow's relation with the West led to a reorientation of Russia's geopolitical vision toward the East and most importantly toward Eurasia. The establishment of the Eurasian Economic Union was instrumental for the promotion of a new vision of wider Eurasian integration.

The issues of adequate treatment of these entities in natural language processing tasks are discussed. The main difficulty here is reliable identification of these entities which could distinguish them from cases where the constituent elements of the idioms appear in the text independently of one another. A case study of one polysemantic syntactic idioms is presented - tol’ko čto ‘just; only’ in contradistinction to the polyseomous particle tol’ko ‘just’.

  9. Causes in the construction of causal law: A psycho-ecological model.

    Young, Gerald

    2010-01-01

    The article presents an integrated psycho-ecological model of the construction of law, with implications for practice in law and mental health. The model is based on a series of concentric circles, each representing a layer of influence on the construction of law. The circle furthest removed from the center represents the influence of culture, society and industry, in particular, and the circle at the center of the circle represents the case at hand, for example, about individual complainant or mass action. The article begins by arguing that basic terms in relation to cause need clarification and also work is needed to disambiguate the concepts involved. After dealing with these issues, the article examines science and mental health. Is the scientific evidence presented by the expert sufficiently reliable and valid to meet admissibility standards of good compared to poor or junk science? Is the research undertaken for court or presented to court biased, with factors hidden, such as links to industry. Are individual evaluations conducted with biased science serving to justify partial conclusions?

    The growth in the building industry, particularly in residential high-rise construction, is having considerable influence on the country's economic development. The scientific hypothesis of the research is that the execution of town-planning programs of high-rise construction depends to a large extent on the management of the provision of material resources for the construction of a millionth city, while the balance model is the most important tool for establishing and determining the ratio between supply and demand for material resources. In order to improve the efficiency of high-rise building management, it is proposed to develop a methodology for managing the provision of construction of large cities with material resources.

    The issues of constructing high-rise, primarily residential, buildings have a great social significance. Not every plot of land, acquired in the Russian Federation is suitable for high-rise construction. Therefore, every construction company that plans to erect a multi-apartment building, a high-rise office building, or a skyscraper must take into account not only technical norms but as well sanitary legislation regulations that set obligatory requirements about insolation of apartments. The article includes a short study of several norms in the Russian legislation regarding insolation of dwellings; analises the problems of judicial interpretation of the statutory limitations. In this aspect it researches the debatable questions arising in practice of state arbitration courts dealing with the lawsuits on allocation of land-plots by the local administration. The analysis of the judicial practice is followed by description of the difficulties facing the developers of land-plots, concerning the project and territorial planning documentation.

    2015-06-01

    Full Text Available The article aims at examining how the main character Snowman’s image is constructed by applying an abundant number of deictic expressions in the Lithuanian, Russian and English versions of the cartoon Snow Postman. The research was based on M. Consten’s conception of direct and indirect reference and the model of visual-verbal cohesion proposed by N. Baumgarten. The study has revealed that in both, Russian and Lithuanian versions of the cartoon, the main character’s dialogues are loaded with deictic expressions which mark the same referents. In this way, the main character is shaped as a dull, forgetful being, unable to store and process a huge amount of information in his head. In the English version, deictic instances are sparsely used, thus the character image is quite different here: the snowman is less absent-minded and fuzzy.

    Full Text Available The author studies the specifics of Russian architect’s work on the example of the activity of prominent architect of Art Nouveau period A.L. Lishnevsky (1868–1942. The special attention is paid to the architect’s relations with the authorities, contractors and workers, as well as with customers and colleagues. The author shows the opinion of citizens about the activities of an architect as a builder and businessman, reveals the main socio-economic problems which the architect faced from the moment of inception and approval of the project prior to its actual implementation. The author attempts to trace the mechanism of professional networking in the architecture environment of that time, and to reveal the peculiarities of private architectural bureaus (“offices”. The attention is paid to the assessment by the architect of their own professional activity. A.L. Lishnevsky’s activity is a good example of architect’s work in the construction business. A native of the city of Kherson, he received the metropolitan education at the Art Academy, then for over six years (1895–1901 he worked as a municipal architect in Elisavetgrad (Kirovograd, since 2016 – Kropivnytsky during the period of rapid economic and cultural growth of the town. After 1901 and up to 1917 he was actively engaged in municipal and private construction in the capital of the Russian Empire, Saint Petersburg. The relevance of the topic is determined by the fact that the Art Nouveau period architect worked in capitalism construction market, and was forced to deal with issues similar to those that the architects of our time solve. The study is based on materials from Russian archives and periodicals of late 19th – early 20th century.

    In the Russian Federation (RF), management of radioactive wastes will be carried out within the framework of the Federal Target Program for management of radioactive wastes and used nuclear materials for the period 1996-2005. The agency within the RF responsible for this program is the Ministry of Russian Federation on Atomic Energy. Current radioactive waste disposal activities are focused on creating regional repositories for wastes generated by radiochemical production, nuclear reactors, science centers, and from other sources outside of the nuclear-fuel cycle (the latter wastes are managed by Scientific and Industrial Association, 'RADON'). Wastes of these types are in temporary storage, with the exception of non-fuel cycle wastes which are in long term storage managed by SAI 'RADON'. The criteria for segregating between underground or near-surface disposal of radioactive waste are based on the radiation fields and radionuclide composition of the wastes. The most progress in creating regional repositories has been made in the Northwest region of Russia. However, development of a detailed design has begun for a test facility in the Northeast for disposal of radioactive wastes generated in Murmansk and Arkhangelsk provinces. The feasibility study for construction of this facility is being evaluated by state monitoring organizations, the heads of administrations of the Arkhangelsk and Murmansk provinces, and Minatom of Russia

    The idea that events are equipped with a partial causal order is central to our understanding of physics in the tested regimes: given two pointlike events A and B, either A is in the causal past of B, B is in the causal past of A, or A and B are space-like separated. Operationally, the meaning of these order relations corresponds to constraints on the possible correlations between experiments performed in the vicinities of the respective events: if A is in the causal past of B, an experimenter at A could signal to an experimenter at B but not the other way around, while if A and B are space-like separated, no signaling is possible in either direction. In the context of a concrete physical theory, the correlations compatible with a given causal configuration may obey further constraints. For instance, space-like correlations in quantum mechanics arise from local measurements on joint quantum states, while time-like correlations are established via quantum channels. Similarly to other variables, however, the causal order of a set of events could be random, and little is understood about the constraints that causality implies in this case. A main difficulty concerns the fact that the order of events can now generally depend on the operations performed at the locations of these events, since, for instance, an operation at A could influence the order in which B and C occur in A’s future. So far, no formal theory of causality compatible with such dynamical causal order has been developed. Apart from being of fundamental interest in the context of inferring causal relations, such a theory is imperative for understanding recent suggestions that the causal order of events in quantum mechanics can be indefinite. Here, we develop such a theory in the general multipartite case. Starting from a background-independent definition of causality, we derive an iteratively formulated canonical decomposition of multipartite causal correlations. For a fixed number of settings and

    A bacterial artificial chromosome library of the causal agent of the Black Sigatoka leaf spot disease of banana and plantain, Mycosphaerella fijiensis, has been constructed using a non-sphaeroplasting technique and characterized using both homologous and heterologous probes. After first and a second size selection of PFGE-fractionated DNA, a ligation was obtained using a 1:4 molar ratio (insert:vector). One hundred random clones were analyzed, and the mean insert size was estimated to be 90 kb. The range of the insert sizes was between 40 and 160 kb. The highest percentage of inserts belonged to the range between 80 and 100 kb; 32% of the inserts had 2 or 3 internal NotI sites. This library consists of 1920 clones, if the genomic size is at least 35 Mb, then this represents 4.9 x genome equivalents, which was supported by hybridization results with homologous and heterologous probes.

  5. Epidemiological causality.

    2005-01-01

    Epidemiological methods, which combine population thinking and group comparisons, can primarily identify causes of disease in populations. There is therefore a tension between our intuitive notion of a cause, which we want to be deterministic and invariant at the individual level, and the epidemiological notion of causes, which are invariant only at the population level. Epidemiologists have given heretofore a pragmatic solution to this tension. Causal inference in epidemiology consists in checking the logical coherence of a causality statement and determining whether what has been found grossly contradicts what we think we already know: how strong is the association? Is there a dose-response relationship? Does the cause precede the effect? Is the effect biologically plausible? Etc. This approach to causal inference can be traced back to the English philosophers David Hume and John Stuart Mill. On the other hand, the mode of establishing causality, devised by Jakob Henle and Robert Koch, which has been fruitful in bacteriology, requires that in every instance the effect invariably follows the cause (e.g., inoculation of Koch bacillus and tuberculosis). This is incompatible with epidemiological causality which has to deal with probabilistic effects (e.g., smoking and lung cancer), and is therefore invariant only for the population.

  6. Causal boundary for stably causal space-times

    The usual boundary constructions for space-times often yield an unsatisfactory boundary set. This problem is reviewed and a new solution is proposed. An explicit identification rule is given on the set of the ideal points of the space-time. This construction leads to a satisfactory boundary point set structure for stably causal space-times. The topological properties of the resulting causal boundary construction are examined. For the stably causal space-times each causal curve has a unique endpoint on the boundary set according to the extended Alexandrov topology. The extension of the space-time through the boundary is discussed. To describe the singularities the defined boundary sets have to be separated into two disjoint sets. (D.Gy.) 8 refs

  7. Multivariate Granger causality between CO2 emissions, energy consumption, FDI (foreign direct investment) and GDP (gross domestic product): Evidence from a panel of BRIC (Brazil, Russian Federation, India, and China) countries

    2011-01-01

    This paper addresses the impact of both economic growth and financial development on environmental degradation using a panel cointegration technique for the period between 1980 and 2007, except for Russia (1992-2007). In long-run equilibrium, CO 2 emissions appear to be energy consumption elastic and FDI inelastic, and the results seem to support the Environmental Kuznets Curve (EKC) hypothesis. The causality results indicate that there exists strong bidirectional causality between emissions and FDI and unidirectional strong causality running from output to FDI. The evidence seems to support the pollution haven and both the halo and scale effects. Therefore, in attracting FDI, developing countries should strictly examine the qualifications for foreign investment or to promote environmental protection through the coordinated know-how and technological transfer with foreign companies to avoid environmental damage. Additionally, there exists strong output-emissions and output-energy consumption bidirectional causality, while there is unidirectional strong causality running from energy consumption to emissions. Overall, the method of managing both energy demand and FDI and increasing both investment in the energy supply and energy efficiency to reduce CO 2 emissions and without compromising the country's competitiveness can be adopted by energy-dependent BRIC countries.

    The authors outline a cognitive and computational account of causal learning in children. They propose that children use specialized cognitive systems that allow them to recover an accurate "causal map" of the world: an abstract, coherent, learned representation of the causal relations among events. This kind of knowledge can be perspicuously understood in terms of the formalism of directed graphical causal models, or Bayes nets. Children's causal learning and inference may involve computations similar to those for learning causal Bayes nets and for predicting with them. Experimental results suggest that 2- to 4-year-old children construct new causal maps and that their learning is consistent with the Bayes net formalism.

In the present paper we complete our identification by incorporating TIP-TIP and TIF-TIF gluings as well. An asymptotic causality condition is found which, for physically important cases, ensures the uniqueness of the endpoints of the non-spacelike curves in the completed spacetime. (author)

    2018-01-01

    It was recently suggested that causal structures are both dynamical, because of general relativity, and indefinite, because of quantum theory. The process matrix formalism furnishes a framework for quantum mechanics on indefinite causal structures, where the order between operations of local laboratories is not definite (e.g., one cannot say whether operation in laboratory A occurs before or after operation in laboratory B ). Here, we develop a framework for "dynamics of causal structures," i.e., for transformations of process matrices into process matrices. We show that, under continuous and reversible transformations, the causal order between operations is always preserved. However, the causal order between a subset of operations can be changed under continuous yet nonreversible transformations. An explicit example is that of the quantum switch, where a party in the past affects the causal order of operations of future parties, leading to a transition from a channel from A to B , via superposition of causal orders, to a channel from B to A . We generalize our framework to construct a hierarchy of quantum maps based on transformations of process matrices and transformations thereof.

    A tightening of the electric power balance in the Nordic countries and increased focus on the supply reliability have made the power import from Russia increasingly more important. The two most important players in the Russian power market are the state-owned companies RAO UES and RosEnergoAtom. RAO UES has already begun to strengthen its presence in the Nordic market. There are indications that there are limits to the growth of power import from Russia, and the Nordic power market cannot be based on it in the future

    2016-01-01

    A recent framework of quantum theory with no global causal order predicts the existence of ‘causally nonseparable’ processes. Some of these processes produce correlations incompatible with any causal order (they violate so-called ‘causal inequalities’ analogous to Bell inequalities ) while others do not (they admit a ‘causal model’ analogous to a local model ). Here we show for the first time that bipartite causally nonseparable processes with a causal model exist, and give evidence that they have no clear physical interpretation. We also provide an algorithm to generate processes of this kind and show that they have nonzero measure in the set of all processes. We demonstrate the existence of processes which stop violating causal inequalities but are still causally nonseparable when mixed with a certain amount of ‘white noise’. This is reminiscent of the behavior of Werner states in the context of entanglement and nonlocality. Finally, we provide numerical evidence for the existence of causally nonseparable processes which have a causal model even when extended with an entangled state shared among the parties. (paper)

    2014-12-01

    Full Text Available In August 2012, pro-Kremlin media in Russia reported widely about an alleged attempt to replay the Pussy Riot stunt at an Orthodox cathedral in Finland. According to the reports, also reproduced by the Russian Foreign Ministry, a Finnish professor was facing several years’ prison sentence in Finnish courts for having attacked the cathedral, carried urine containers, spread homosexual propaganda and committed various acts of blasphemy. Even if the Finnish media, eyewitnesses and state authorities repeatedly denied the claims, the story became a useful way for pro-Kremlin forces to normalise the Pussy Riot trial in Russia. The episode was an example of the recent politicisation of religion, gender and sexuality in the Russian public sphere.

    Directory of Open Access Journals (Sweden)

    Mikula, Maja

    2013-06-01

    Full Text Available The Orthodox island monastery of Valaam in Russian Karelia is today a popular destination for Finnish tourists visiting Russia’s western borderlands. Many of these tourists are descendants of the Karelians who had evacuated the area following World War II. The monastery’s institutionally sanctioned genealogies construct it as the civilizing force, which had brought Christian enlightenment to the local heathen population. This discursive template is played out in the way the place is presented to visitors, with each highlight telling a carefully constructed story that promotes the monastery’s significance for the Russian religious and national identity. Yet, drawing on lived experience, as well as on popular culture, family lore and meanings from collective memory, the Finnish visitors break the monolithic official discourse and produce a complex “thirdspace” in their own measure. This paper is based on participant observation and semi-structured interviews conducted during a homeland visit to Ladogan Karelia in June 2010.

  17. Causal relationship: a new tool for the causal characterization of Lorentzian manifolds

    International Nuclear Information System (INIS)

    Garcia-Parrado, Alfonso; Senovilla, Jose M M

    2003-01-01

    We define and study a new kind of relation between two diffeomorphic Lorentzian manifolds called a causal relation, which is any diffeomorphism characterized by mapping every causal vector of the first manifold onto a causal vector of the second. We perform a thorough study of the mathematical properties of causal relations and prove in particular that two given Lorentzian manifolds (say V and W) may be causally related only in one direction (say from V to W, but not from W to V). This leads us to the concept of causally equivalent (or isocausal in short) Lorentzian manifolds as those mutually causally related and to a definition of causal structure over a differentiable manifold as the equivalence class formed by isocausal Lorentzian metrics upon it. Isocausality is a more general concept than the conformal relationship, because we prove the remarkable result that a conformal relation φ is characterized by the fact of being a causal relation of the particular kind in which both φ and φ -1 are causal relations. Isocausal Lorentzian manifolds are mutually causally compatible, they share some important causal properties, and there are one-to-one correspondences, which are sometimes non-trivial, between several classes of their respective future (and past) objects. A more important feature is that they satisfy the same standard causality constraints. We also introduce a partial order for the equivalence classes of isocausal Lorentzian manifolds providing a classification of all the causal structures that a given fixed manifold can have. By introducing the concept of causal extension we put forward a new definition of causal boundary for Lorentzian manifolds based on the concept of isocausality, and thereby we generalize the traditional Penrose constructions of conformal infinity, diagrams and embeddings. In particular, the concept of causal diagram is given. Many explicit clarifying examples are presented throughout the paper

    This paper reports that American oil workers discouraged by bleak employment opportunities in the U.S. petroleum industry face increasing competition abroad from Russians seeking a living wage. Moscow's Zagrantrud (Foreign Labor) firm believes millions of Russian skilled and unskilled workers in many occupations will try to find jobs in other countries. The Russian enterprise says it is selecting a group of construction workers to build a refinery in Columbia. Kuwait also wants Russian construction personnel. Russia is especially eager to find overseas work for petroleum industry workers who have lost their jobs in Viet Nam and Cuba. The number of specialists from the former U.S.S.R. in Cuba, many of them engaged in oil exploration and production or pipeline and refinery construction, has fallen from several thousand 2 years ago to 250 at present as Moscow's relations with Havana cooled

  20. Causal reasoning in physics

    Frisch, Mathias

    2014-01-01

    Much has been written on the role of causal notions and causal reasoning in the so-called 'special sciences' and in common sense. But does causal reasoning also play a role in physics? Mathias Frisch argues that, contrary to what influential philosophical arguments purport to show, the answer is yes. Time-asymmetric causal structures are as integral a part of the representational toolkit of physics as a theory's dynamical equations. Frisch develops his argument partly through a critique of anti-causal arguments and partly through a detailed examination of actual examples of causal notions in physics, including causal principles invoked in linear response theory and in representations of radiation phenomena. Offering a new perspective on the nature of scientific theories and causal reasoning, this book will be of interest to professional philosophers, graduate students, and anyone interested in the role of causal thinking in science.

  1. Theories of Causality

    2010-03-01

    There are a wide range of views on causality. To some (e.g. Karl Popper) causality is superfluous. Bertrand Russell said ``In advanced science the word cause never occurs. Causality is a relic of a bygone age.'' At the other extreme Rafael Sorkin and L. Bombelli suggest that space and time do not exist but are only an approximation to a reality that is simply a discrete ordered set, a ``causal set.'' For them causality IS reality. Others, like Judea Pearl and Nancy Cartwright are seaking to build a complex fundamental theory of causality (Causality, Cambridge Univ. Press, 2000) Or perhaps a theory of causality is simply the theory of functions. This is more or less my take on causality.

    Full Text Available Causality is a fundamental notion in every field of science. Since the times of Aristotle, causal relationships have been a matter of study as a way to generate knowledge and provide for explanations. In this paper I review the notion of causality through different scientific areas such as physics, biology, engineering, etc. In the scientific area, causality is usually seen as a precise relation: the same cause provokes always the same effect. But in the everyday world, the links between cause and effect are frequently imprecise or imperfect in nature. Fuzzy logic offers an adequate framework for dealing with imperfect causality, so a few notions of fuzzy causality are introduced.

  3. RUSSIAN INDUSTRY INVESTMENT SITUATION

    Full Text Available The actual deficiency of investment into Russian industry innovative development increases its technological drag from industries of countries with developed markets. Although the rate of investment into real sectors of Russian economics mid 2000 was higher compared to the previous period, annual investment amounts were much lower than in 1990. At present, highest investment amounts are directed to industry extractive branches and to the commerce. Amounts invested to various economy branches do not correspond to their contribution to the country’sGross Added Product; particularly underinvested are manufacturing industry branches. At present, foreign share in the country economy total investment makes 15–18%. Recently, most interesting for foreigners was investment to machine-building branches with overwhelming part (for example, 90% in 2007–2008 of foreign investment into the machine-building industry being directed to creation of new automobile plants. Today, first place in the list of foreign investors’ preferences in Russia is taken by the machine-tool construction sector.

  6. The philosophical implications of Russian conceptualism

    Conceptualism identifies itself as a predominantly Russian-Soviet mode of thinking. In the West, the correlation between ideological signs and observable reality has been persistently validated through scientific and economic practice; while in Russia, traditionally, reality itself has been constructed from ideological signs generated by its ruling minds as a kind of hyper-reality. Thus, Russian Conceptualism sees itself not as a mere replica of Western postmodernism, but as a reflection of the underlying structures of Russian history, where the signs of reality have always been subject to ideological manipulation.

  8. Causal imprinting in causal structure learning.

    Science.gov (United States)

    Taylor, Eric G; Ahn, Woo-Kyoung

    2012-11-01

    Suppose one observes a correlation between two events, B and C, and infers that B causes C. Later one discovers that event A explains away the correlation between B and C. Normatively, one should now dismiss or weaken the belief that B causes C. Nonetheless, participants in the current study who observed a positive contingency between B and C followed by evidence that B and C were independent given A, persisted in believing that B causes C. The authors term this difficulty in revising initially learned causal structures "causal imprinting." Throughout four experiments, causal imprinting was obtained using multiple dependent measures and control conditions. A Bayesian analysis showed that causal imprinting may be normative under some conditions, but causal imprinting also occurred in the current study when it was clearly non-normative. It is suggested that causal imprinting occurs due to the influence of prior knowledge on how reasoners interpret later evidence. Consistent with this view, when participants first viewed the evidence showing that B and C are independent given A, later evidence with only B and C did not lead to the belief that B causes C.

  9. Management of Russian military plutonium

    1996-01-01

    The objective of this paper is to propose and discuss a solution which enables storing as quickly as possible all weapons-grade plutonium from Russian military program in a way which would prevent diversion. Two main conditions apply to this solution. First, it should be achieved in a manner acceptable to Russian government, notably by preserving plutonium for possible future energy production, and second, the economics of the total system should be good enough to ensure no charge or limited charge for the storage of plutonium. A proposal is made to store plutonium in a specially designed fast reactor or specially designed reactor core. This solution could be favorable in comparison to other solutions applying the above mentioned goal and conditions. Additionally the proposed solution would have the following side advantages: utilizing available personnel and installations of the Russian nuclear complex; providing possible basis for decommissioning of older and less safe Russian reactors; giving experience of construction and operation of a series of sodium-cooled fast reactors. The major problem however is the need for large capital investment with the risk of getting no adequate return on investment due to difficult political and economic situation in Russia

    Many of our decisions refer to actions that have a causal impact on the external environment. Such actions may not only allow for the mere learning of expected values or utilities but also for acquiring knowledge about the causal structure of our world. We used a repeated decision-making paradigm to examine what kind of knowledge people acquire in such situations and how they use their knowledge to adapt to changes in the decision context. Our studies show that decision makers' behavior is strongly contingent on their causal beliefs and that people exploit their causal knowledge to assess the consequences of changes in the decision problem. A high consistency between hypotheses about causal structure, causally expected values, and actual choices was observed. The experiments show that (a) existing causal hypotheses guide the interpretation of decision feedback, (b) consequences of decisions are used to revise existing causal beliefs, and (c) decision makers use the experienced feedback to induce a causal model of the choice situation even when they have no initial causal hypotheses, which (d) enables them to adapt their choices to changes of the decision problem.

  11. Causal localizations in relativistic quantum mechanics

    Castrigiano, Domenico P. L.; Leiseifer, Andreas D.

    2015-07-01

    Causal localizations describe the position of quantum systems moving not faster than light. They are constructed for the systems with finite spinor dimension. At the center of interest are the massive relativistic systems. For every positive mass, there is the sequence of Dirac tensor-localizations, which provides a complete set of inequivalent irreducible causal localizations. They obey the principle of special relativity and are fully Poincaré covariant. The boosters are determined by the causal position operator and the other Poincaré generators. The localization with minimal spinor dimension is the Dirac localization. Thus, the Dirac equation is derived here as a mere consequence of the principle of causality. Moreover, the higher tensor-localizations, not known so far, follow from Dirac's localization by a simple construction. The probability of localization for positive energy states results to be described by causal positive operator valued (PO-) localizations, which are the traces of the causal localizations on the subspaces of positive energy. These causal Poincaré covariant PO-localizations for every irreducible massive relativistic system were, all the more, not known before. They are shown to be separated. Hence, the positive energy systems can be localized within every open region by a suitable preparation as accurately as desired. Finally, the attempt is made to provide an interpretation of the PO-localization operators within the frame of conventional quantum mechanics attributing an important role to the negative energy states.

    The program of constructing the S-matrix by means of causality in quantum field theory goes back to Stueckelberg and Bogoliubov. Epstein and Glaser proposed an axiomatic construct where ultraviolet divergences do not appear, leading directly to the renormalized perturbation series. They have shown that in the causal theory the UV problem is a consequence of incorrect distribution splitting. This paper studies the causal theory in (2+1)D Qed

    Full Text Available The research concerns the computational analyses of local strength of the umbilical mast (UM, which is designed for the prelaunch preparation and launch security of the space rocket (SR "SOYUZ-2" of 1B stage.Based on the finite elements method, modeling and calculation of local strength for the most loaded UM elements are conducted using Russian program complex «APM WINMACHINE». The paper gives a justification for choosing the program complex «APM WINMACHINE, as a program calculation device.In calculating the principles of a local analysis are used. Physical models of the UM particular constructive units are formed to observe them under certain boundary conditions: forces and movements. Parameters of boundary conditions are determined in terms of stress-strain condition of UM simplified model as a whole.As the research results, the paper presents the finite element models of two UM constructive units, namely a joint of the mast farm branches with strengthening of the mast rotating part and an element in the UM bottom rotating part (“the spine”. Besides, there are also the calculated results of the local strength of abovementioned UM rotating part units: a general pattern of the stress distribution with stress values exceeding the allowable ones.The research results allow us to draw conclusions that the units under consideration have performance capability and require their constructive strengthening.The UM developers have taken in consideration recommendations, based on the UM rotating part local strength calculation, making appropriate correction in the project documentation. The experience gained in using the «APM WINMACHINE» allowed us to support the conclusion that it is efficient to solve the tasks of defining stress-strain condition of complicated spatial constructions.

    We argue that the degrees of freedom in a d-dimensional CFT can be reorganized in an insightful way by studying observables on the moduli space of causal diamonds (or equivalently, the space of pairs of timelike separated points). This 2 d-dimensional space naturally captures some of the fundamental nonlocality and causal structure inherent in the entanglement of CFT states. For any primary CFT operator, we construct an observable on this space, which is defined by smearing the associated one-point function over causal diamonds. Known examples of such quantities are the entanglement entropy of vacuum excitations and its higher spin generalizations. We show that in holographic CFTs, these observables are given by suitably defined integrals of dual bulk fields over the corresponding Ryu-Takayanagi minimal surfaces. Furthermore, we explain connections to the operator product expansion and the first law of entanglemententropy from this unifying point of view. We demonstrate that for small perturbations of the vacuum, our observables obey linear two-derivative equations of motion on the space of causal diamonds. In two dimensions, the latter is given by a product of two copies of a two-dimensional de Sitter space. For a class of universal states, we show that the entanglement entropy and its spin-three generalization obey nonlinear equations of motion with local interactions on this moduli space, which can be identified with Liouville and Toda equations, respectively. This suggests the possibility of extending the definition of our new observables beyond the linear level more generally and in such a way that they give rise to new dynamically interacting theories on the moduli space of causal diamonds. Various challenges one has to face in order to implement this idea are discussed.

    Full Text Available Rasch’s unidimensional models for measurement show how to connect object measures (e.g., reader abilities, measurement mechanisms (e.g., machine-generated cloze reading items, and observational outcomes (e.g., counts correct on reading instruments. Substantive theory shows what interventions or manipulations to the measurement mechanism can be traded off against a change to the object measure to hold the observed outcome constant. A Rasch model integrated with a substantive theory dictates the form and substance of permissible interventions. Rasch analysis, absent construct theory and an associated specification equation, is a black box in which understanding may be more illusory than not. Finally, the quantitative hypothesis can be tested by comparing theory-based trade-off relations with observed trade-off relations. Only quantitative variables (as measured support such trade-offs. Note that to test the quantitative hypothesis requires more than manipulation of the algebraic equivalencies in the Rasch model or descriptively fitting data to the model. A causal Rasch model involves experimental intervention/manipulation on either reader ability or text complexity or a conjoint intervention on both simultaneously to yield a successful prediction of the resultant observed outcome (count correct. We conjecture that when this type of manipulation is introduced for individual reader text encounters and model predictions are consistent with observations, the quantitative hypothesis is sustained.

In this paper, which is based on evidence...... from corpus data, weight is demonstrated to have a very significant influence on word order in Russian. Specifically, four constructions are tested: Postverbal PPs, the double object construction, adversity impersonals and the order of S, V and O. In all cases the same pattern emerges: The heavier...

  3. Causal Analysis After Haavelmo

    Heckman, James; Pinto, Rodrigo

    2014-01-01

    Haavelmo's seminal 1943 and 1944 papers are the first rigorous treatment of causality. In them, he distinguished the definition of causal parameters from their identification. He showed that causal parameters are defined using hypothetical models that assign variation to some of the inputs determining outcomes while holding all other inputs fixed. He thus formalized and made operational Marshall's (1890) ceteris paribus analysis. We embed Haavelmo's framework into the recursive framework of Directed Acyclic Graphs (DAGs) used in one influential recent approach to causality (Pearl, 2000) and in the related literature on Bayesian nets (Lauritzen, 1996). We compare the simplicity of an analysis of causality based on Haavelmo's methodology with the complex and nonintuitive approach used in the causal literature of DAGs—the “do-calculus” of Pearl (2009). We discuss the severe limitations of DAGs and in particular of the do-calculus of Pearl in securing identification of economic models. We extend our framework to consider models for simultaneous causality, a central contribution of Haavelmo. In general cases, DAGs cannot be used to analyze models for simultaneous causality, but Haavelmo's approach naturally generalizes to cover them. PMID:25729123

  6. Agency, time and causality

    Thomas eWidlok

    2014-11-01

    Full Text Available Cognitive Scientists interested in causal cognition increasingly search for evidence from non-WEIRD people but find only very few cross-cultural studies that specifically target causal cognition. This article suggests how information about causality can be retrieved from ethnographic monographs, specifically from ethnographies that discuss agency and concepts of time. Many apparent cultural differences with regard to causal cognition dissolve when cultural extensions of agency and personhood to non-humans are taken into account. At the same time considerable variability remains when we include notions of time, linearity and sequence. The article focuses on ethnographic case studies from Africa but provides a more general perspective on the role of ethnography in research on the diversity and universality of causal cognition.

    Full Text Available Computation models such as circuits describe sequences of computation steps that are carried out one after the other. In other words, algorithm design is traditionally subject to the restriction imposed by a fixed causal order. We address a novel computing paradigm beyond quantum computing, replacing this assumption by mere logical consistency: We study non-causal circuits, where a fixed time structure within a gate is locally assumed whilst the global causal structure between the gates is dropped. We present examples of logically consistent non-causal circuits outperforming all causal ones; they imply that suppressing loops entirely is more restrictive than just avoiding the contradictions they can give rise to. That fact is already known for correlations as well as for communication, and we here extend it to computation.

  8. The Russian gas industry

    The Russian Federation holds the world's largest proven natural gas reserves, and produces more natural gas than any other nation. Russian exports of gas to Europe and the other nations of the Commonwealth of Independent States (CIS) have a significant impact on natural gas markets throughout Europe and Asia. The aim of this three part study is to inform the international energy and investment community about the current status of the Russian gas industry and the prospects for its future development through 2010. It is also intended to provide an opportunity for the appropriate authorities in the Russian Federation to assess the needs of the industry and to consider areas for possible collaboration with the international investment community and international organizations in a rapidly changing economic and business environment. The study was prepared by the Energy Branch of the United Nations Department for Development Support and Management Services (UN/DDSMS). It was financed by the United Nations Development Programme (UNDP). Part I describes Russian gas reserves and potential resources, and overviews the country's gas producing, pipeline and distribution industries. Additionally, it summarizes the markets for Russian natural gas including domestic and external markets. It discusses the primary economics and potential factors that currently impact the Russian gas industry during the Federation's transition toward a market economy. Part II highlights possible directions for the development of the Russian gas resource base, including upstream gas production and downstream marketing in five-, ten- and fifteen-year time frames. It projects export opportunities for Russian Federation gas and evaluates the options for shaping regional and international markets. Part III addresses the legal and regulatory framework and fiscal regime of the Russian gas industry. It also reviews the major investment requirements and the equipment and training needs of the Russian gas

    Objective The objective of this study was to explore the conditions necessary to assign causal status to headache triggers. Background The term “headache trigger” is commonly used to label any stimulus that is assumed to cause headaches. However, the assumptions required for determining if a given stimulus in fact has a causal-type relationship in eliciting headaches have not been explicated. Methods A synthesis and application of Rubin’s Causal Model is applied to the context of headache causes. From this application the conditions necessary to infer that one event (trigger) causes another (headache) are outlined using basic assumptions and examples from relevant literature. Results Although many conditions must be satisfied for a causal attribution, three basic assumptions are identified for determining causality in headache triggers: 1) constancy of the sufferer; 2) constancy of the trigger effect; and 3) constancy of the trigger presentation. A valid evaluation of a potential trigger’s effect can only be undertaken once these three basic assumptions are satisfied during formal or informal studies of headache triggers. Conclusions Evaluating these assumptions is extremely difficult or infeasible in clinical practice, and satisfying them during natural experimentation is unlikely. Researchers, practitioners, and headache sufferers are encouraged to avoid natural experimentation to determine the causal effects of headache triggers. Instead, formal experimental designs or retrospective diary studies using advanced statistical modeling techniques provide the best approaches to satisfy the required assumptions and inform causal statements about headache triggers.

  10. Causality re-established.

    Science.gov (United States)

    D'Ariano, Giacomo Mauro

    2018-07-13

    Causality has never gained the status of a 'law' or 'principle' in physics. Some recent literature has even popularized the false idea that causality is a notion that should be banned from theory. Such misconception relies on an alleged universality of the reversibility of the laws of physics, based either on the determinism of classical theory, or on the multiverse interpretation of quantum theory, in both cases motivated by mere interpretational requirements for realism of the theory. Here, I will show that a properly defined unambiguous notion of causality is a theorem of quantum theory, which is also a falsifiable proposition of the theory. Such a notion of causality appeared in the literature within the framework of operational probabilistic theories. It is a genuinely theoretical notion, corresponding to establishing a definite partial order among events, in the same way as we do by using the future causal cone on Minkowski space. The notion of causality is logically completely independent of the misidentified concept of 'determinism', and, being a consequence of quantum theory, is ubiquitous in physics. In addition, as classical theory can be regarded as a restriction of quantum theory, causality holds also in the classical case, although the determinism of the theory trivializes it. I then conclude by arguing that causality naturally establishes an arrow of time. This implies that the scenario of the 'block Universe' and the connected 'past hypothesis' are incompatible with causality, and thus with quantum theory: they are both doomed to remain mere interpretations and, as such, are not falsifiable, similar to the hypothesis of 'super-determinism'.This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'. © 2018 The Author(s).

  15. The Russian oil

    International Nuclear Information System (INIS)

    Rucker, Laurent

    2003-01-01

    This article proposes a brief discussion of various assessments of Russian oil reserves, of the evolutions of Russian oil production (Russia is the second world producer after Saudi Arabia), of the distribution of Russian oil exports among various regions, and of the decrease of Russian oil consumption between 1992 and 2002. It describes the evolution of the actor system as the oil sector has been largely privatised since 1992, and indicates the main companies which should control the Russia market on a medium term. It also discusses the obstacles for the development of Production Sharing Agreements (PSA) between these companies. It addresses the issue of modernisation of the oil transport system as its status and its condition are often an obstacle to oil export for Russian companies. The article finally discusses the price issue, the relationship between Russia and other OPEC countries, and the need for huge investments

  16. Tachyons and causal paradoxes

    International Nuclear Information System (INIS)

    Maund, J.B.

    1979-01-01

    Although the existence of tachyons is not ruled out by special relativity, it appears that causal paradoxes will arise if there are tachyons. The usual solutions to these paradoxes employ some form of the reinterpretation principle. In this paper it is argued first that, the principle is incoherent, second, that even if it is not, some causal paradoxes remain, and third, the most plausible ''solution,'' which appeals to boundary conditions of the universe, will conflict with special relativity

    The physical meaning and the geometrical interpretation of causality implementation in classical field theories are discussed. Causality in field theory are kinematical constraints dynamically implemented via solutions of the field equation, but in a limit of zero-distance from the field sources part of these constraints carries a dynamical content that explains old problems of classical electrodynamics away with deep implications to the nature of physicals interactions.

  19. Spatial hypersurfaces in causal set cosmology

    International Nuclear Information System (INIS)

    Major, Seth A; Rideout, David; Surya, Sumati

    2006-01-01

    Within the causal set approach to quantum gravity, a discrete analogue of a spacelike region is a set of unrelated elements, or an antichain. In the continuum approximation of the theory, a moment-of-time hypersurface is well represented by an inextendible antichain. We construct a richer structure corresponding to a thickening of this antichain containing non-trivial geometric and topological information. We find that covariant observables can be associated with such thickened antichains and transitions between them, in classical sequential growth models of causal sets. This construction highlights the difference between the covariant measure on causal set cosmology and the standard sum-over-histories approach: the measure is assigned to completed histories rather than to histories on a restricted spacetime region. The resulting re-phrasing of the sum-over-histories may be fruitful in other approaches to quantum gravity

  1. Causality violation, gravitational shockwaves and UV completion

    2016-03-18

    The effective actions describing the low-energy dynamics of QFTs involving gravity generically exhibit causality violations. These may take the form of superluminal propagation or Shapiro time advances and allow the construction of “time machines”, i.e. spacetimes admitting closed non-spacelike curves. Here, we discuss critically whether such causality violations may be used as a criterion to identify unphysical effective actions or whether, and how, causality problems may be resolved by embedding the action in a fundamental, UV complete QFT. We study in detail the case of photon scattering in an Aichelburg-Sexl gravitational shockwave background and calculate the phase shifts in QED for all energies, demonstrating their smooth interpolation from the causality-violating effective action values at low-energy to their manifestly causal high-energy limits. At low energies, these phase shifts may be interpreted as backwards-in-time coordinate jumps as the photon encounters the shock wavefront, and we illustrate how the resulting causality problems emerge and are resolved in a two-shockwave time machine scenario. The implications of our results for ultra-high (Planck) energy scattering, in which graviton exchange is modelled by the shockwave background, are highlighted.

    2015-01-01

    Cochrane collaboration has made a huge contribution to the development of evidence-based medicine; Cochrane work is the international gold standard of independent, credible and reliable high-quality information in medicine. Over the past 20 years the Cochrane Collaboration helped transforming decision-making in health and reforming it significantly, saving lives and contributing to longevity [1]. Until recently, Cochrane evidence were available only in English, which represents a significant barrier to their wider use in non-English speaking countries. To provide access to evidence, obtained from Cochrane Reviews, for health professionals and general public (from non-English-speaking countries), bypassing language barriers, Cochrane collaboration in 2014 initiated an international project of translating Plain language summaries of Cochrane Reviews into other languages [2, 3]. Russian translations of Plain language summaries were started in May 2014 by the team from Kazan Federal University (Department of Basic and Clinical Pharmacology; 2014-2015 as an Affiliated Centre in Tatarstan of the Nordic Cochrane Centre, since August 2015 as Cochrane Russia, a Russian branch of Cochrane Nordic, Head - Liliya Eugenevna Ziganshina) on a voluntary basis. To assess the quality of Russian translations of Cochrane Plain Language Summaries (PLS) and their potential impact on the Russian speaking community through user feedback with the overarching aim of furthering the translations project. We conducted the continuous online survey via Google Docs. We invited respondents through the electronic Russian language discussion forum on Essential Medicines (E-lek), links to survey on the Russian Cochrane.org website, invitations to Cochrane contributors registered in Archie from potential Russian-speaking countries. We set up the survey in Russian and English. The respondents were asked to respond to the questionnaire regarding the relevance and potential impact of the Cochrane Russian

    Causality is the fabric of our dynamic world. We all make frequent attempts to reason causation relationships of everyday events (e.g., what was the cause of my headache, or what has upset Alice?). We attempt to manage causality all the time through planning and scheduling. The greatest scientific discoveries are usually about causality (e.g., Newton found the cause for an apple to fall, and Darwin discovered natural selection). Meanwhile, we continue to seek a comprehensive understanding about the causes of numerous complex phenomena, such as social divisions, economic crisis, global warming, home-grown terrorism, etc. Humans analyse and reason causality based on observation, experimentation and acquired a priori knowledge. Today's technologies enable us to make observations and carry out experiments in an unprecedented scale that has created data mountains everywhere. Whereas there are exciting opportunities to discover new causation relationships, there are also unparalleled challenges to benefit from such data mountains. In this article, we present a case for developing a new piece of ICT, called Causality Discovery Technology. We reason about the necessity, feasibility and potential impact of such a technology.

    A small contract signed in FY92 with the Khlopin Radium Institute marked the beginning of the Russian Separations program. Under this contract the Khlopin Radium Institute performed laboratory and dynamic hot-cell testing using cobalt dicarbollide technology on simulated radioactive wastes similar to those found at DOE sites in the United States. The current scope of investigation has been extended to identify prospective technologies for application to other United States needs. The Khlopin Radium Institute project served as a model for three other pilot scale technology development projects. The premise of the pilot scale projects is to enable Russian scientists to demonstrate their technology in the context of DOE needs, using Russian technical expertise has proven to be a cost-effective means of screening Russian technologies

  7. A quantum causal discovery algorithm

    Giarmatzi, Christina; Costa, Fabio

    2018-03-01

    Finding a causal model for a set of classical variables is now a well-established task—but what about the quantum equivalent? Even the notion of a quantum causal model is controversial. Here, we present a causal discovery algorithm for quantum systems. The input to the algorithm is a process matrix describing correlations between quantum events. Its output consists of different levels of information about the underlying causal model. Our algorithm determines whether the process is causally ordered by grouping the events into causally ordered non-signaling sets. It detects if all relevant common causes are included in the process, which we label Markovian, or alternatively if some causal relations are mediated through some external memory. For a Markovian process, it outputs a causal model, namely the causal relations and the corresponding mechanisms, represented as quantum states and channels. Our algorithm opens the route to more general quantum causal discovery methods.

  12. Causal inference in econometrics

    CERN Document Server

    Kreinovich, Vladik; Sriboonchitta, Songsak

    2016-01-01

    This book is devoted to the analysis of causal inference which is one of the most difficult tasks in data analysis: when two phenomena are observed to be related, it is often difficult to decide whether one of them causally influences the other one, or whether these two phenomena have a common cause. This analysis is the main focus of this volume. To get a good understanding of the causal inference, it is important to have models of economic phenomena which are as accurate as possible. Because of this need, this volume also contains papers that use non-traditional economic models, such as fuzzy models and models obtained by using neural networks and data mining techniques. It also contains papers that apply different econometric models to analyze real-life economic dependencies.

    Quantum mechanics, in principle, allows for processes with indefinite causal order. However, most of these causal anomalies have not yet been detected experimentally. We show that every such process can be simulated experimentally by means of non-Markovian dynamics with a measurement on additional degrees of freedom. In detail, we provide an explicit construction to implement arbitrary a causal processes. Furthermore, we give necessary and sufficient conditions for open system dynamics with measurement to yield processes that respect causality locally, and find that tripartite entanglement and nonlocal unitary transformations are crucial requirements for the simulation of causally indefinite processes. These results show a direct connection between three counter-intuitive concepts: entanglement, non-Markovianity, and causal non-separability.

    2016-01-01

    Rosatom is the world leader for the export of nuclear technologies. 34 reactors of Russian technology are being built or planned worldwide. Most reactors proposed by Rosatom are third generation VVER-1200 units with an electric power output of 1200 MWe. Although the nuclear island is always built by Rosatom, the remain of the plant can be subcontracted to other enterprises and European companies are sought because they would bring a european quality touch to Russian works. One of the main assets of Rosatom is to propose an integrated offer from supplying nuclear fuel to managing nuclear waste via the turnkey building of nuclear power plants. Another important asset is the financial assistance of the Russian state through state credit or the support from Russian national banks that appears to be a decisive advantage in the international competition to win markets. We have to temper the Russian export perspectives by noting that most projects are set in countries that are prone to instabilities and that the economic crisis affecting Russia has a negative impact on its financial means.

    We show that pulse solutions of the wave equation can be expressed as time Fourier superpositions of scalar monochromatic beam wave functions (solutions of the Helmholtz equation). This formulation is shown to be equivalent to Bateman's integral expression for solutions of the wave equation, for axially symmetric solutions. A closed-form one-parameter solution of the wave equation, containing no backward-propagating parts, is constructed from a beam which is the tight-focus limit of two families of beams. Application is made to transverse electric and transverse magnetic pulses, with evaluation of the energy, momentum and angular momentum for a pulse based on the general localized and causal form. Such pulses can be represented as superpositions of photons. Explicit total energy and total momentum values are given for the one-parameter closed-form pulse.

  1. Optimal causal inference: estimating stored information and approximating causal architecture.

    Science.gov (United States)

    Still, Susanne; Crutchfield, James P; Ellison, Christopher J

    2010-09-01

    We introduce an approach to inferring the causal architecture of stochastic dynamical systems that extends rate-distortion theory to use causal shielding--a natural principle of learning. We study two distinct cases of causal inference: optimal causal filtering and optimal causal estimation. Filtering corresponds to the ideal case in which the probability distribution of measurement sequences is known, giving a principled method to approximate a system's causal structure at a desired level of representation. We show that in the limit in which a model-complexity constraint is relaxed, filtering finds the exact causal architecture of a stochastic dynamical system, known as the causal-state partition. From this, one can estimate the amount of historical information the process stores. More generally, causal filtering finds a graded model-complexity hierarchy of approximations to the causal architecture. Abrupt changes in the hierarchy, as a function of approximation, capture distinct scales of structural organization. For nonideal cases with finite data, we show how the correct number of the underlying causal states can be found by optimal causal estimation. A previously derived model-complexity control term allows us to correct for the effect of statistical fluctuations in probability estimates and thereby avoid overfitting.

MÉTODOS: O processo investigativo utilizou métodos de abordagem sócio-antropológica tendo como base o desenvolvimento de um modelo de causalidade construído por meio da realização de grupos focais com representantes da comunidade. RESULTADOS: Os resultados do estudo demonstraram que a utilização de abordagens participativas estimula a auto-estima da comunidade e o empoderamento sobre os fatores que determinam seus problemas. O modelo causal construído revela que a insegurança alimentar e nutricional, para as comunidades, estabelece que fatores históricos relacionados à posse da terra e ao seu uso atual baseado em práticas predatórias, são os aspectos fundamentais na compreensão da rede de determinação causal da insegurança alimentar e nutricional. CONCLUSÃO: O racismo e suas nuances sociais têm contribuído para a invisibilidade social dessas comunidades nas políticas públicas brasileiras. As comunidades quilombolas se consideram em insegurança alimentar e nutricional e indicam que a abertura da Rodovia BR-163 pode ser uma ameaça ao etno-desenvolvimento sustentável na região. E referem que o desenvolvimento econômico esperado com a abertura desta rodovia, se não for realizado com base na participação da comunidade, pode aumentar a fome, a miséria e o racismo.OBJECTIVE: This work describes results based on the participative and encompassing development of a model of causal determination done in six quilombola communities of Santarém, Pará State, regarding the causality of food and nutrition insecurity with the construction of the BR-163 highway.

    2006-01-01

    The departure of Mikhail Khodorkovsky has brought an end to the idyllic times of supplies of Russian oil to the MOL-Slovnaft group. The group used to purchase oil directly from Yukos. But now brokers have again entered the Central European oil business. And their aim is to take control over all of the oil business. The Russians demonstrated the changed situation to Slovakia last autumn: you will either accept the new model, or there will be problems with oil deliveries. Consumers got the message. The main brokers of Russian oil in Central Europe are the Swiss companies Glencore and Fisotra. Little information is available regarding these commodity brokers. But the information available is sufficient to indicate that these are not small companies. Glencore undertakes 3% of all international oil trades. With an annual turnover of 72 billions USD, it was the biggest Swiss company by turnover in 2004. Fisotra also has an extensive product portfolio. It offers financial and commercial services and does not hide its good relations with Russian oil companies. Between 1994 and 1998, it managed their financial operations with major western companies such as BP, Cargill, Elf, Exxon, Shell, Total, and Mutsubishi and also with Glencore. Fisotra states that some of its clients achieved an annual turnover of 1.5 billions USD. At present, the Swiss brokers receive a fee of 1 to 1.5 USD per barrel. The Russian political elite must be aware of these brokerage services as the oil transport through the transit system is closely monitored by the state owned company Transneft. (authors)

  9. Researching Informal Labour Migration: Russian Realities

    Directory of Open Access Journals (Sweden)

    Lev Perepelkin

    2006-09-01

    Full Text Available Modern Russian society is affected by “non-resident informal employment”: a regular productive activity that is not firmly and officially registered in accordance with Russian foreign labour regulations. A specific characteristic of this phenomenon in Russia is that the multimillion flow of CIS working age citizens enters Russia absolutely legally, but with the intention of working in the so-called shadow or semi-legal economy. The authors’ main aim is to present a complex and balanced evaluation of the situation. On one hand they argue that this labour migration was of some use to Russia, i.e. in the early 1990’s large groups of “informal” foreign workers filled an economic niche, unpopular among local labour force (construction and repair, small sized retail trade etc. and thus enabled to solve the deficit in many services and satisfy needs for basic products. On the other hand, a negative reflection of such shadow employment exceeded all of its conjuncture benefits from post-soviet “gastarbeiter” labour.. The permanency of these migration contingents undermines the Russian labour market, not only from the point of wages and working conditions. It provides and maintains not only unfair labour practices, but also the deterioration of common morals and ethics: the devaluation of positive values, the predominance of cynic pragmatism in Russian people and legislative nihilism.

    1969-12-01

    Full Text Available In Russia defensive works were not less important than in Western Europe. Russian chronicles are full of reports of the building of towns, of their siege and defence. In Ancient Russian the word town meant not a town in the modern sense, but only a fortified settlement as distinct from an unfortified one. Thus the concept town applied to medieval towns proper and to citadels, feudal castles and even fortified villages. Every population centre with a wall round it was called a town. Moreover, until the 17th century this word was frequently applied to mean the fortifications themselves.

  12. Causal events enter awareness faster than non-causal events

    Full Text Available Philosophers have long argued that causality cannot be directly observed but requires a conscious inference (Hume, 1967. Albert Michotte however developed numerous visual phenomena in which people seemed to perceive causality akin to primary visual properties like colour or motion (Michotte, 1946. Michotte claimed that the perception of causality did not require a conscious, deliberate inference but, working over 70 years ago, he did not have access to the experimental methods to test this claim. Here we employ Continuous Flash Suppression (CFS—an interocular suppression technique to render stimuli invisible (Tsuchiya & Koch, 2005—to test whether causal events enter awareness faster than non-causal events. We presented observers with ‘causal’ and ‘non-causal’ events, and found consistent evidence that participants become aware of causal events more rapidly than non-causal events. Our results suggest that, whilst causality must be inferred from sensory evidence, this inference might be computed at low levels of perceptual processing, and does not depend on a deliberative conscious evaluation of the stimulus. This work therefore supports Michotte’s contention that, like colour or motion, causality is an immediate property of our perception of the world.

  16. Causal inference based on counterfactuals

    Directory of Open Access Journals (Sweden)

    Höfler M

    2005-09-01

    Full Text Available Abstract Background The counterfactual or potential outcome model has become increasingly standard for causal inference in epidemiological and medical studies. Discussion This paper provides an overview on the counterfactual and related approaches. A variety of conceptual as well as practical issues when estimating causal effects are reviewed. These include causal interactions, imperfect experiments, adjustment for confounding, time-varying exposures, competing risks and the probability of causation. It is argued that the counterfactual model of causal effects captures the main aspects of causality in health sciences and relates to many statistical procedures. Summary Counterfactuals are the basis of causal inference in medicine and epidemiology. Nevertheless, the estimation of counterfactual differences pose several difficulties, primarily in observational studies. These problems, however, reflect fundamental barriers only when learning from observations, and this does not invalidate the counterfactual concept.

  17. Causal inference in public health.

    Science.gov (United States)

    Glass, Thomas A; Goodman, Steven N; Hernán, Miguel A; Samet, Jonathan M

    2013-01-01

    Causal inference has a central role in public health; the determination that an association is causal indicates the possibility for intervention. We review and comment on the long-used guidelines for interpreting evidence as supporting a causal association and contrast them with the potential outcomes framework that encourages thinking in terms of causes that are interventions. We argue that in public health this framework is more suitable, providing an estimate of an action's consequences rather than the less precise notion of a risk factor's causal effect. A variety of modern statistical methods adopt this approach. When an intervention cannot be specified, causal relations can still exist, but how to intervene to change the outcome will be unclear. In application, the often-complex structure of causal processes needs to be acknowledged and appropriate data collected to study them. These newer approaches need to be brought to bear on the increasingly complex public health challenges of our globalized world.

If so the diagrams can be queried to produce mathematical expressions for causal effects in ter...

    Shoham, Efrat

    2010-12-01

    The unique nature of Israeli society as an immigrant society has also affected the prison population in Israel. This article focuses on a social and cultural phenomenon that particularly characterizes the prisoners of Russian origin, the phenomenon of tattoos. Using postmodernist theories, the article examines the function of the tattoo among Russian prisoners and the role it plays in constructing the criminal self-identity of these inmates in Israeli prisons. The tattoos observed during 2005-2006 among the Russian prisoners in four major Israeli prisons reflect the values of the Russian criminal subculture from which they evolved and were imported. This subculture is characterized by a hierarchical class structure and manifestations of machismo, domination, defiance, rebellion, and open antagonism against the Establishment and its representatives.

    2017-05-01

    Full Text Available The population of the Russian desman in all historical areas is currently no more than 8000–10,000 individuals. The estimated population size of the Russian desman is based on direct surveys during 2010–2016. We observed over 266 km of the coastline in eight regions where the desman lives. Since the early 20th century the number of specimens has been steadily declining. In addition to the previously described factors that determine the reduction of the population size, such as land reclamation, the construction of hydroelectric stations and the flourishing of poaching at the end of the last century, the status of the Russian desman population is adversely affected by periodic droughts and the absence of floods. Currently Protected Areas remain as the only passive measure to protect the Russian desman in the absence of a programme to species protection nor state support.

  2. Causal electromagnetic interaction equations

    International Nuclear Information System (INIS)

    Zinoviev, Yury M.

    2011-01-01

    For the electromagnetic interaction of two particles the relativistic causal quantum mechanics equations are proposed. These equations are solved for the case when the second particle moves freely. The initial wave functions are supposed to be smooth and rapidly decreasing at the infinity. This condition is important for the convergence of the integrals similar to the integrals of quantum electrodynamics. We also consider the singular initial wave functions in the particular case when the second particle mass is equal to zero. The discrete energy spectrum of the first particle wave function is defined by the initial wave function of the free-moving second particle. Choosing the initial wave functions of the free-moving second particle it is possible to obtain a practically arbitrary discrete energy spectrum.

  3. Ethnic Russian Minority in Estonia

    2016-12-01

    Full Text Available The article examines the position of Russians in Estonia and their relation with ethnic Estonians. The author analyzes models of the society integration introduced by Tallinn after 1991. The results raise questions regarding language education in Estonia, the proficiency level of Estonian is getting widely known by Russians, but on the other hand, there is still a significant part of the population that cannot communicate in Estonian. Those who have a good command of Estonian tend to be better integrated and to coexist with both Estonians and Russians. Russians living in Estonia are supposed to be equally involved in social and political life of the state. The potential of all residents has to be effectively and considerably used, especially when the number of population is decreasing. The position of Russians in Estonia is a major domestic and bilateral issue in the relations with the Russian Federation.

    The changes in the Russian metallurgy, in particular, electric furnace steelmaking, having occurred in the recent years are analyzed. The main increase in the steelmaking output is due to putting into operation of new electric furnaces in new miniworks and enterprises equipped earlier with open-hearth furnaces. Reaching the rated capacity of a furnace in Russia substantially lags behind foreign enterprises. Only 30-35% of the Russian market of corrosion-resistant steel are provided by Russian metal.

    2013-03-01

    Granger causality is a standard tool for the description of directed interaction of network components and is popular in many scientific fields including econometrics, neuroscience and climate science. For time series that can be modeled as bivariate auto-regressive processes we analytically derive an expression for spectrally decomposed Granger Causality (SDGC) and show that this quantity depends only on two out of four groups of model parameters. Then we present examples of such processes whose SDGC expose paradoxical behavior in the sense that causality is high for frequency ranges with low spectral power. For avoiding misinterpretations of Granger causality analysis we propose to complement it by partial spectral analysis. Our findings are illustrated by an example from brain electrophysiology. Finally, we draw implications for the conventional definition of Granger causality. Bernstein Center for Computational Neuroscience Goettingen

  11. On causality of extreme events

    Directory of Open Access Journals (Sweden)

    Massimiliano Zanin

    2016-06-01

    Full Text Available Multiple metrics have been developed to detect causality relations between data describing the elements constituting complex systems, all of them considering their evolution through time. Here we propose a metric able to detect causality within static data sets, by analysing how extreme events in one element correspond to the appearance of extreme events in a second one. The metric is able to detect non-linear causalities; to analyse both cross-sectional and longitudinal data sets; and to discriminate between real causalities and correlations caused by confounding factors. We validate the metric through synthetic data, dynamical and chaotic systems, and data representing the human brain activity in a cognitive task. We further show how the proposed metric is able to outperform classical causality metrics, provided non-linear relationships are present and large enough data sets are available.

  13. Neural Correlates of Causal Power Judgments

    Directory of Open Access Journals (Sweden)

    Denise Dellarosa Cummins

    2014-12-01

    Full Text Available Causal inference is a fundamental component of cognition and perception. Probabilistic theories of causal judgment (most notably causal Bayes networks derive causal judgments using metrics that integrate contingency information. But human estimates typically diverge from these normative predictions. This is because human causal power judgments are typically strongly influenced by beliefs concerning underlying causal mechanisms, and because of the way knowledge is retrieved from human memory during the judgment process. Neuroimaging studies indicate that the brain distinguishes causal events from mere covariation, and between perceived and inferred causality. Areas involved in error prediction are also activated, implying automatic activation of possible exception cases during causal decision-making.

    2003-12-01

    Experiment confirms that information cannot be transmitted faster than the speed of light. Ever since Einstein stated that nothing can travel faster than light, physicists have delighted in finding exceptions. One after another, observations of such 'superluminal' propagation have been made. However, while some image or pattern- such as the motion of a spotlight projected on a distant wall - might have appeared to travel faster than light, it seemed that there was no way to use the superluminal effect to transmit energy or information. In recent years, the superluminal propagation of light pulses through certain media has led to renewed controversy. In 1995, for example, Guenther Nimtz of the University of Cologne encoded Mozart's 40th Symphony on a microwave beam, which he claimed to have transmitted at a speed faster than light. Others maintain that such a violation of Einstein's speed limit would wreak havoc on our most fundamental ideas about causality, allowing an effect to precede its cause. Relativity teaches us that sending a signal faster than light would be equivalent to sending it backwards in time. (U.K.)

  15. Causal aspects of diffraction

    International Nuclear Information System (INIS)

    Crawford, G.N.

    1981-01-01

    The analysis is directed at a causal description of photon diffraction, which is explained in terms of a wave exerting real forces and providing actual guidance to each quantum of energy. An undulatory PSI wave is associated with each photon, and this wave is assumed to imply more than an informative probability function, so that it actually carries real energy, in much the same way as does an electro-magnetic wave. Whether or not it may be in some way related to the electromagnetic wave is left as a matter of on-going concern. A novel application of the concept of a minimum energy configuration is utilized; that is, a system of energy quanta seeks out relative positions and orientations of least mutual energy, much as an electron seeks its Bohr radius as a position of least mutual energy. Thus the concept implies more a guiding interaction of the PSI waves than an interfering cancellation of these waves. Similar concepts have been suggested by L. de Broglie and D. Bohm

  16. ["Karoshi" and causal relationships].

    Science.gov (United States)

    Hamajima, N

    1992-08-01

    This paper aims to introduce a measure for use by physicians for stating the degree of probable causal relationship for "Karoshi", ie, a sudden death from cerebrovascular diseases or ischemic heart diseases under occupational stresses, as well as to give a brief description for legal procedures associated with worker's compensation and civil trial in Japan. It is a well-used measure in epidemiology, "attributable risk percent (AR%)", which can be applied to describe the extent of contribution to "Karoshi" of the excess occupational burdens the deceased worker was forced to bear. Although several standards such as average occupational burdens for the worker, average occupational burdens for an ordinary worker, burdens in a nonoccupational life, and a complete rest, might be considered for the AR% estimation, the average occupational burdens for an ordinary worker should normally be utilized as a standard for worker's compensation. The adoption of AR% could be helpful for courts to make a consistent judgement whether "Karoshi" cases are compensatable or not.

  18. Russian gas in 1993

    International Nuclear Information System (INIS)

    Wilson, D.C.

    1994-01-01

    Natural gas output in Russia fell by 3.5% in 1993. This followed decades of rapid growth in production reaching a peak in 1991 and a minor fall in 1993. Gas consumption also peaked in 1991 and fell by 5% over the two following years. The major cause of the decline in consumption is the fall in electricity demand which has accompanied the economic recession. Gas has accounted for about 60% of the reduction in fuel consumption by power stations. Gas consumption by industrial and municipal boilers has also dropped steeply although household and other municipal consumption has increased. The fall in demand does not wholely account for the fall in production, however. Apart from Yamburg, all operational gas fields have now reached the stage of declining production. Government officials are talking tentatively of 1997 as the turning point for the Russian economy and following this, the demand for gas will rise again. It is not certain, however, that the industry will be able to meet the increased demand which is anticipated. Most of the increased production will have to come from new fields in the Yamal Peninsular the development of which is proceeding much more slowly than planned. In the longer term, possibly in the early years of the next century, the Shtokmanovsk gasfield in the Barents Sea may be developed. Other aspects of the Russian gas industry briefly covered are reserves, financing of exploratory drilling, investment, intra-CIS trade and exports and privatisation of the state owned company Garyprom.

  20. Russian JV workovers proliferating

    Energy Technology Data Exchange (ETDEWEB)

    1992-11-09

    Well remediation is gathering momentum in Russia as more companies apply western technology to idle wells. Western petroleum technology is being widely hailed as the best way to halt the decline in crude oil production in Russia and other members of the former Soviet Union. More than 20,000 Russian wells are estimated idle, many of which observers say could be returned to service with western know-how. Progress has been outlined on two significant projects in the Komi and Chechen autonomous republics of Russia: KomiQuest Ltd., a joint venture of an international group of companies and Komi republic agencies, has used a Russian rig and crew to work over four wells and started producing oil in one of four Vozey area oil fields in the Komi republic. A Chechen republic delegation led by President Dzhahar Jusyavitch Dudaev last month in Houston let a 2 year contract worth about $100 million to Enforce Energy Corp., San Antonio, covering workover, drilling, and other services in two oil fields north of the Chechen capital of Grozny.

    The present position and future potential of the Russian oil company Tatneft are assessed. Tatneft, the eighteenth largest oil company in the world, has 85 oil fields and over 20,700 production wells. In 1995, it increased its production by 6% to 504,000bpd and its crude oil exports outside Russia were 213,000bpd. The company forms the basis of the oil industry in the semi-autonomous republic of Tatarstan. Tafneft became a joint stock company in May 1994 with the government of Tatarstan as the largest shareholder with a 46% stake. Although Tafneft produces far more crude than Conoco or YPF, its market capitalisation per barrel of production is only 5% of these companies. Its long-term future lies in successfully increasing production and enhancing financial performance. The former is being addressed through enhanced oil recovery methods and various joint ventures are being entered into with western partners in order to tap foreign expertise and to finance modern equipment. The achievement of the latter requires an improvement towards world prices of the price for Russian domestic crude and a reduction in the tax burden away from revenue towards a profits basis. (UK)

    .69-4.17. Adjustment for other variables reduced the size of these odds ratios, but they remained strikingly large for circulatory disease (adjusted OR=3.54, 95% CI 1.76-7.13 and considerable for external causes (adjusted OR 1.75, 95% CI 1.02-3.00. These may be underestimates of the true effects as nearly all of them increased when employment status (which can in part at least be seen as being on the causal pathway was excluded from the final model. In summary, however, our key finding is that a history of heavy drinking in the recent past is strongly associated with risk of death from circulatory disease. This provides the first individual-level evidence in support of the hypothesis that episodic heavy drinking is key to explaining the heavy burden of circulatory disease mortality among Russian men of working age.

  3. QED representation for the net of causal loops

    Science.gov (United States)

    Ciolli, Fabio; Ruzzi, Giuseppe; Vasselli, Ezio

    2015-06-01

    The present work tackles the existence of local gauge symmetries in the setting of Algebraic Quantum Field Theory (AQFT). The net of causal loops, previously introduced by the authors, is a model independent construction of a covariant net of local C*-algebras on any 4-dimensional globally hyperbolic space-time, aimed to capture structural properties of any reasonable quantum gauge theory. Representations of this net can be described by causal and covariant connection systems, and local gauge transformations arise as maps between equivalent connection systems. The present paper completes these abstract results, realizing QED as a representation of the net of causal loops in Minkowski space-time. More precisely, we map the quantum electromagnetic field Fμν, not free in general, into a representation of the net of causal loops and show that the corresponding connection system and the local gauge transformations find a counterpart in terms of Fμν.

  4. Principal stratification in causal inference.

    Science.gov (United States)

    Frangakis, Constantine E; Rubin, Donald B

    2002-03-01

    Many scientific problems require that treatment comparisons be adjusted for posttreatment variables, but the estimands underlying standard methods are not causal effects. To address this deficiency, we propose a general framework for comparing treatments adjusting for posttreatment variables that yields principal effects based on principal stratification. Principal stratification with respect to a posttreatment variable is a cross-classification of subjects defined by the joint potential values of that posttreatment variable tinder each of the treatments being compared. Principal effects are causal effects within a principal stratum. The key property of principal strata is that they are not affected by treatment assignment and therefore can be used just as any pretreatment covariate. such as age category. As a result, the central property of our principal effects is that they are always causal effects and do not suffer from the complications of standard posttreatment-adjusted estimands. We discuss briefly that such principal causal effects are the link between three recent applications with adjustment for posttreatment variables: (i) treatment noncompliance, (ii) missing outcomes (dropout) following treatment noncompliance. and (iii) censoring by death. We then attack the problem of surrogate or biomarker endpoints, where we show, using principal causal effects, that all current definitions of surrogacy, even when perfectly true, do not generally have the desired interpretation as causal effects of treatment on outcome. We go on to forrmulate estimands based on principal stratification and principal causal effects and show their superiority.

  5. Discrete causal theory emergent spacetime and the causal metric hypothesis

    CERN Document Server

    Dribus, Benjamin F

    2017-01-01

    This book evaluates and suggests potentially critical improvements to causal set theory, one of the best-motivated approaches to the outstanding problems of fundamental physics. Spacetime structure is of central importance to physics beyond general relativity and the standard model. The causal metric hypothesis treats causal relations as the basis of this structure. The book develops the consequences of this hypothesis under the assumption of a fundamental scale, with smooth spacetime geometry viewed as emergent. This approach resembles causal set theory, but differs in important ways; for example, the relative viewpoint, emphasizing relations between pairs of events, and relationships between pairs of histories, is central. The book culminates in a dynamical law for quantum spacetime, derived via generalized path summation.

A causal implicature is a type of Gricean relation implicature, a highly context dependent form of inference. As we shall see, causal implicatures are important...... to generate clarification requests"; as a result we can model task-oriented dialogue as an interactive process locally structured by negotiation of the underlying task. We give several examples of Frolog-human dialog, discuss the limitations imposed by the classical planning paradigm, and indicate...

The basic theory of functional equations includes functional differential equations with causal operators. Functional Equations with Causal Operators explains the connection between equations with causal operators and the classical types of functional equations encountered by mathematicians and engineers. It details the fundamentals of linear equations and stability theory and provides several applications and examples.

  9. Causal inference in nonlinear systems: Granger causality versus time-delayed mutual information

    The Granger causality (GC) analysis has been extensively applied to infer causal interactions in dynamical systems arising from economy and finance, physics, bioinformatics, neuroscience, social science, and many other fields. In the presence of potential nonlinearity in these systems, the validity of the GC analysis in general is questionable. To illustrate this, here we first construct minimal nonlinear systems and show that the GC analysis fails to infer causal relations in these systems—it gives rise to all types of incorrect causal directions. In contrast, we show that the time-delayed mutual information (TDMI) analysis is able to successfully identify the direction of interactions underlying these nonlinear systems. We then apply both methods to neuroscience data collected from experiments and demonstrate that the TDMI analysis but not the GC analysis can identify the direction of interactions among neuronal signals. Our work exemplifies inference hazards in the GC analysis in nonlinear systems and suggests that the TDMI analysis can be an appropriate tool in such a case.

  12. Ukrainian-Russian Mixed Speech “Suržyk” within the System of Ukrainian and Russian Interaction

    Full Text Available The question of different forms of real and/or presumed mixed speech, a consequence of the interaction between Ukrainian and Russian and widely known as “Suržyk,” remains central in much of contemporary Ukrainian and, more widely, East Slavic sociolinguistic and language contact research. This article pursues a twofold aim: first, I intend to reaffirm my personal hypothesis on the formation process of this mixed speech, which has at times been cited without attribution in the scholarly literature. Second, the paper aims to examine the functioning of Ukrainian-Russian Suržyk within a broader sociolinguistic framework that takes into account other forms of language interaction. Ukrainian-Russian mixed speech in fact has to be assessed and separated from other factors, such as the Ukrainian variety of Russian, dialects, etc. This approach has rarely been applied in previous studies on the topic. The role played by current language ideology is a further essential aspect in establishing which language elements should be attributed to Ukrainian-Russian Suržik. This undoubtedly affects the average speaker’s judgment about the degree of authenticity of Ukrainian forms. One can note a tendency to restrict the synonymic potential of Ukrainian in favor of lexemes and constructions that are dissimilar to Russian. This situation tends to alter the language consciousness of younger generations of Ukrainian speakers, who are likely to perceive as Russian (and therefore part of the Ukrainian-Russian mix elements that are in fact authentic Ukrainian speech elements. These and other related aspects will be the object of my discussion.

    Full Text Available The article analyzes the development of Russian-Saudi political interaction after the restoration (at that time of Soviet-Saudi relations of bilateral relations in September 1990. The article focuses on the role of the Russian Muslim community in shaping the Russian politics towards Riyadh in the 1990-2000s. The authors state there are both periods of “crises” and detente in the development of Russian-Saudi political interaction that were marked by events in Chechnya and former Yugoslavia in 1994-2000, “Arab Spring” 2011, the post-September 2015 era, the Russian anti-terrorist campaign in Syria. The alternation of these periods is the constant of Russian-Saudi political contacts, despite the similarity in the approaches of both sides to the ways and methods of solving crisis situations in the Middle East region, as well as the Saudi’s pro-Russian position regarding the change in the status of the Crimea and the situation in the east of Ukraine. The general attitude of both sides towards ISIS and Jabha al-Nusra as a source of terrorism, regional instability and the challenge of international security does not remove the two main contradictions that divide Moscow and Riyadh – attitude toward the official Syrian regime and the Iran’s regional policy. The study comes to the conclusion that Russia and Saudi Arabia are interested (albeit for various reasons in diversifying their foreign policy and foreign economic relations.

  18. Overview of the Russian nuclear industry

    International Nuclear Information System (INIS)

    2008-02-01

    In 2004, President Poutine decided to replace the atomic energy ministry (Minatom) by the federal atomic energy agency (Rosatom). Several projects were launched during the next two years which aimed at bringing back Russia to the fore front of the world leaders of nuclear energy use and nuclear technology export. In 2007, Rosatom agency was changed to a public holding company and a new company, named Atomenergoprom, was created which gathers all civil nuclear companies (AtomEnergoMash for the exploitation of power plants, Technabsexport (Tenex) specialized in enrichment or Atomstryexport in charge of export activities). Thus, Rosatom is at the head of all civilian and military nuclear companies, of all research centers, and of all nuclear and radiological safety facilities. In 2006, Russian nuclear power plants supplied 15.8% of the whole power consumption. Russia wishes to develop its nuclear program with the construction of new reactors in order to reach a nuclear electricity share of 25% from now to 2020. This paper presents first the 2007 institutional reform of the Russian atomic sector, and the three sectorial federal programmes: 1 - development of the nuclear energy industrial complex for the 2007-2010 era and up to 2015 (future power plants, nuclear fuel centers and reactor prototypes), 2 - nuclear safety and radioprotection for the 2008-2015 era (waste management, remedial actions, radiation protection), 3 - military program (confidential). Then, the paper presents: the international actions (export of Russian technology, cooperation agreements, non-proliferation), the situation of the existing nuclear park (reactors in operation, stopped, under construction and in project), the fuel cycle activities (production of natural uranium, enrichment, fuel fabrication, spent fuel storage, reprocessing, waste management), the nuclear R and D in Russia, and the nuclear safety authority.

  19. The Russian Orthodox Church and atheism

    Directory of Open Access Journals (Sweden)

    Teuvo Laitila

    2012-06-01

    Full Text Available After the collapse of the Soviet Union in 1991, the religious tide in Russia has been quick to rise. During the Soviet era, religion – particularly Orthodox Christianity and Islam – was considered to be one of the ‘enemies of the people’. Since the late 1990s however, Russian politicians at all levels of the power structure have associated themselves either with the Orthodox, or on some occasions with the Muslim, clergy. The present state of affairs in the relations between religion and the state are well illustrated by the cordial liaison of the late Patriarch Aleksii II with President Vladimir Putin and the equally warm involvement of President Dmitry Medvedev, and his wife Svetlana Medvedeva, with the new Patriarch Kirill, who was elected in January 2009. Some have even argued that ‘today’ (in 2004 the Church and state are so extensively intertwined that one can no longer consider Russia to be a secular state. Polls seem to support the claim. While in 1990 only 24 per cent of Russians identified themselves as Orthodox, in the sense that they felt themselves to be Russians as well, in 2008 the number was 73 per cent. However, less than 10 per cent, and in Moscow perhaps only 2 per cent do actually live out their religiosity.Why did Russia turn towards religion? Is religion chosen in an attempt to legitimise power, or in order to consolidate political rule after atheist-communist failure? My guess is that the answer to both is affirmative. Moreover, whatever the personal convictions of individual Russians, including politicians, religious, mainly Orthodox Christian, rhetoric and rituals are used to make a definitive break with the communist past and to create, or re-create, a Greater Russia (see Simons 2009. In such an ideological climate, atheism has little chance of thriving, whereas there is a sort of ‘social demand’ for its critique.I therefore focus on what the Russian Orthodox Church (ROC has had to say about atheism and

    Paper deals with the building of new gas line between Russia and the Ukraine. In September 2003 Gazprom and Naftohaz Ukraine signed protocol about conditions of Russian gas transit through Ukrainian area for 2004. There is guaranteed quantity of transported gas on the level of 127,8 billions cubic meters by Russian side, 110 billions of it should next lead to Europe. Treaty refills long-term contract between Naftohaz and Gazprom about gas transit through Ukraine for period 2003-2013. Both countries and its companies plan to accept particular capital decision about building of new gas line Novopskov-Uzgorod till end of this year, which will be parallel with gas line Soyuz. It will allow to enlarge transportation system capacity by 28 billion cubic meters. Construction of about 1600 km long ducting system will require 1.6 billion USD by annual capacity about 15 billion cubic meters. If capacity would be doubled by construction of another compressor stations, capital expenses rise to 2.2 billions USD. It can be completely built in 7 years. Its linear part with one compressor can be already built in 3 years. Slovensky Plynarensky Podnik (SPP) would certainly have advantages from possible realisation of new gas line and from consequential transit increase. (Author)

  3. Putting a cap on causality violations in causal dynamical triangulations

    Ambjoern, Jan; Loll, Renate; Westra, Willem; Zohren, Stefan

    2007-01-01

    The formalism of causal dynamical triangulations (CDT) provides us with a non-perturbatively defined model of quantum gravity, where the sum over histories includes only causal space-time histories. Path integrals of CDT and their continuum limits have been studied in two, three and four dimensions. Here we investigate a generalization of the two-dimensional CDT model, where the causality constraint is partially lifted by introducing branching points with a weight g s , and demonstrate that the system can be solved analytically in the genus-zero sector. The solution is analytic in a neighborhood around weight g s = 0 and cannot be analytically continued to g s = ∞, where the branching is entirely geometric and where one would formally recover standard Euclidean two-dimensional quantum gravity defined via dynamical triangulations or Liouville theory

    Татьяна Сергеевна Семичевская

    2016-12-01

    Full Text Available This article deals with the process of establishment and development the Russian revival style in Russian Empire’s architecture of the 19th - early 20th centuries. During this period Russian society experienced intense changes that included innovations in technology, engineering and the art of building. Taking its origin from “Russian-byzantine” style in orthodox church building, the Russian revival style developed as a mixture of tradition and innovation. This eclectic style was inspired by the romantic revival movement of Western Europe and based on the interest in the historic monuments of the nation, especially in examples of pre-Peterine Russian architecture of the 17th century. The historicism of Russian Revival style resonated with the popular nationalism and pan-Slavism of the period. New style became a manifestation of the Russian national idea depicting in stone the specialty and uniqueness of our history and culture. Today the increasing interest to national cultural heritage actualizes the investigations of this extraordinary period of creativity represented by works of such famous architects as V. Stasov, K. Thon, V. Sherwood, I. Ropet and others. The appealing to “Russian-byzantine” style in modern church construction shows the power and vitality of its creative impulse.

  8. Bayesian networks improve causal environmental ...

    Science.gov (United States)

    Rule-based weight of evidence approaches to ecological risk assessment may not account for uncertainties and generally lack probabilistic integration of lines of evidence. Bayesian networks allow causal inferences to be made from evidence by including causal knowledge about the problem, using this knowledge with probabilistic calculus to combine multiple lines of evidence, and minimizing biases in predicting or diagnosing causal relationships. Too often, sources of uncertainty in conventional weight of evidence approaches are ignored that can be accounted for with Bayesian networks. Specifying and propagating uncertainties improve the ability of models to incorporate strength of the evidence in the risk management phase of an assessment. Probabilistic inference from a Bayesian network allows evaluation of changes in uncertainty for variables from the evidence. The network structure and probabilistic framework of a Bayesian approach provide advantages over qualitative approaches in weight of evidence for capturing the impacts of multiple sources of quantifiable uncertainty on predictions of ecological risk. Bayesian networks can facilitate the development of evidence-based policy under conditions of uncertainty by incorporating analytical inaccuracies or the implications of imperfect information, structuring and communicating causal issues through qualitative directed graph formulations, and quantitatively comparing the causal power of multiple stressors on value

  10. Hierarchical organisation of causal graphs

    Dziopa, P.

    1993-01-01

    This paper deals with the design of a supervision system using a hierarchy of models formed by graphs, in which the variables are the nodes and the causal relations between the variables of the arcs. To obtain a representation of the variables evolutions which contains only the relevant features of their real evolutions, the causal relations are completed with qualitative transfer functions (QTFs) which produce roughly the behaviour of the classical transfer functions. Major improvements have been made in the building of the hierarchical organization. First, the basic variables of the uppermost level and the causal relations between them are chosen. The next graph is built by adding intermediary variables to the upper graph. When the undermost graph has been built, the transfer functions parameters corresponding to its causal relations are identified. The second task consists in the upwelling of the information from the undermost graph to the uppermost one. A fusion procedure of the causal relations has been designed to compute the QFTs relevant for each level. This procedure aims to reduce the number of parameters needed to represent an evolution at a high level of abstraction. These techniques have been applied to the hierarchical modelling of nuclear process. (authors). 8 refs., 12 figs

  11. Entropy for theories with indefinite causal structure

    Markes, Sonia; Hardy, Lucien

    2011-01-01

    Any theory with definite causal structure has a defined past and future, be it defined by light cones or an absolute time scale. Entropy is a concept that has traditionally been reliant on a definite notion of causality. However, without a definite notion of causality, the concept of entropy is not all lost. Indefinite causal structure results from combining probabilistic predictions and dynamical space-time. The causaloid framework lays the mathematical groundwork to be able to treat indefinite causal structure. In this paper, we build on the causaloid mathematics and define a causally-unbiased entropy for an indefinite causal structure. In defining a causally-unbiased entropy, there comes about an emergent idea of causality in the form of a measure of causal connectedness, termed the Q factor.

    2009-08-01

    Full Text Available This work presents a causal conception of metaphysical modality in which a state of affairs is metaphysically possible if and only if it can be caused (in the past, the present or the future by current entities. The conception is contrasted with what is called the “combinatorial” conception of modality, in which everything can co-exist with anything else. This work explains how the notion of ‘causality’ should be construed in the causal theory, what difference exists between modalities thus defined from nomological modality, how accessibility relations between possible worlds should be interpreted, and what is the relation between the causal conception and the necessity of origin.

    Full Text Available One of the more challenging issues in epidemiological research is being able to provide an unbiased estimate of the causal exposure-disease effect, to assess the possible etiological mechanisms and the implication for public health. A major source of bias is confounding, which can spuriously create or mask the causal relationship. In the last ten years, methodological research has been developed to better de_ne the concept of causation in epidemiology and some important achievements have resulted in new statistical models. In this review, we aim to show how a technique the well known by statisticians, i.e. standardization, can be seen as a method to estimate causal e_ects, equivalent under certain conditions to the inverse probability treatment weight procedure.

It postulates that the core meanings of causal assertions are deterministic and refer to temporally-ordered sets of possibilities: A causes B to occur means that given A, B occurs, whereas A enables B to occur means that given A, it is possible for B to occur. The paper shows how mental models represent such assertions, and how these models underlie deductive, inductive, and abductive reasoning yielding explanations. It reviews evidence both to corroborate the theory and to account for phenomena sometimes taken to be incompatible with it.

    Full Text Available The article analyses the image of a scientist represented in recent Russian movies. The article discusses two groups of questions: (1 nature and role of popular science in the life of society; (2 national features of scientific cultures. The article agues that popular science should not be conceived as a week copy of the real science. On the contrary, modern models of science communication assume that popular science have its own value and is able to influence scientific practices. Simultaneously we assume, that since popular science is less integrated with international scientific norms, it can easer reveal national traditions of scientific life. As a result, the analyze of recent Russian movies shows that the tradition established in Peter I times for Russian scientists to work out their self-identity in concern with Russian state still exists (scientist- state supporter/scientist- oppositionist. Actually the modern interpretation of dilemma between state patriotism and liberalism given by modern movies shows that Russian scientist don't have real choice, because they loose anyway whereas the state always wins. So owing to recent movies this representation of hopeless destiny of a scientist is becoming widespread in Russian public culture.

    Dumas, O; Siroux, V; Le Moual, N; Varraso, R

    2014-02-01

    Epidemiological research is mostly based on observational studies. Whether such studies can provide evidence of causation remains discussed. Several causal analysis methods have been developed in epidemiology. This paper aims at presenting an overview of these methods: graphical models, path analysis and its extensions, and models based on the counterfactual approach, with a special emphasis on marginal structural models. Graphical approaches have been developed to allow synthetic representations of supposed causal relationships in a given problem. They serve as qualitative support in the study of causal relationships. The sufficient-component cause model has been developed to deal with the issue of multicausality raised by the emergence of chronic multifactorial diseases. Directed acyclic graphs are mostly used as a visual tool to identify possible confounding sources in a study. Structural equations models, the main extension of path analysis, combine a system of equations and a path diagram, representing a set of possible causal relationships. They allow quantifying direct and indirect effects in a general model in which several relationships can be tested simultaneously. Dynamic path analysis further takes into account the role of time. The counterfactual approach defines causality by comparing the observed event and the counterfactual event (the event that would have been observed if, contrary to the fact, the subject had received a different exposure than the one he actually received). This theoretical approach has shown limits of traditional methods to address some causality questions. In particular, in longitudinal studies, when there is time-varying confounding, classical methods (regressions) may be biased. Marginal structural models have been developed to address this issue. In conclusion, "causal models", though they were developed partly independently, are based on equivalent logical foundations. A crucial step in the application of these models is the

  2. Emergent Geometry from Entropy and Causality

    Science.gov (United States)

    Engelhardt, Netta

    In this thesis, we investigate the connections between the geometry of spacetime and aspects of quantum field theory such as entanglement entropy and causality. This work is motivated by the idea that spacetime geometry is an emergent phenomenon in quantum gravity, and that the physics responsible for this emergence is fundamental to quantum field theory. Part I of this thesis is focused on the interplay between spacetime and entropy, with a special emphasis on entropy due to entanglement. In general spacetimes, there exist locally-defined surfaces sensitive to the geometry that may act as local black hole boundaries or cosmological horizons; these surfaces, known as holographic screens, are argued to have a connection with the second law of thermodynamics. Holographic screens obey an area law, suggestive of an association with entropy; they are also distinguished surfaces from the perspective of the covariant entropy bound, a bound on the total entropy of a slice of the spacetime. This construction is shown to be quite general, and is formulated in both classical and perturbatively quantum theories of gravity. The remainder of Part I uses the Anti-de Sitter/ Conformal Field Theory (AdS/CFT) correspondence to both expand and constrain the connection between entanglement entropy and geometry. The AdS/CFT correspondence posits an equivalence between string theory in the "bulk" with AdS boundary conditions and certain quantum field theories. In the limit where the string theory is simply classical General Relativity, the Ryu-Takayanagi and more generally, the Hubeny-Rangamani-Takayanagi (HRT) formulae provide a way of relating the geometry of surfaces to entanglement entropy. A first-order bulk quantum correction to HRT was derived by Faulkner, Lewkowycz and Maldacena. This formula is generalized to include perturbative quantum corrections in the bulk at any (finite) order. Hurdles to spacetime emergence from entanglement entropy as described by HRT and its quantum

    We propose a Bayesian nonparametric approach (BNP) for causal inference on quantiles in the presence of many confounders. In particular, we define relevant causal quantities and specify BNP models to avoid bias from restrictive parametric assumptions. We first use Bayesian additive regression trees (BART) to model the propensity score and then construct the distribution of potential outcomes given the propensity score using a Dirichlet process mixture (DPM) of normals model. We thoroughly evaluate the operating characteristics of our approach and compare it to Bayesian and frequentist competitors. We use our approach to answer an important clinical question involving acute kidney injury using electronic health records. © 2018, The International Biometric Society.

  4. Russian LNG: The Long Road to Export

    On December 1, 2013 a law on liquefied natural gas (LNG) export liberalization came into legal force in Russia. The law grants two categories of companies other than Russia's state gas giant Gazprom and its subsidiary companies the right to export LNG: (1) users of mineral resources that have a license to construct an LNG plant or to send their gas production for liquefaction, and (2) companies that are more than 50% owned by the Russian government, for gas produced from Russian offshore fields or under production-sharing agreements. This is-without exaggeration-a historic decision for the Russian gas industry, the path to which was certainly not easy. Recent years have seen a radical change in the global economic climate, which has changed the dynamics of the European gas market (gas demand decline and Russian gas import reduction, changing pricing mechanism for a much higher share of spot indexing, European Commission anti-trust investigations against Gazprom, etc) and is increasingly pushing Russia to diversify its gas exports. However, diversifying exports through the development of LNG has proven to be not so simple. Over the past 20 years, with the exception of the Sakhalin-2 project, structured under a project-sharing agreement (PSA) rather than in the framework of national legislation, all other projects failed to come close to completion. The Kharasavey and Baltic LNG projects were abandoned in the early stages of project evaluation, while the Shtokman project progressed to the point of the operating company being created, but in the end was postponed indefinitely. The first stage of LNG development in Russia ended in failure. However, the Russian government considers the development of LNG exports to be a priority, which can be evidenced in all official policy papers. It is believed that LNG will help in achieving a set of objectives, namely: increasing the absolute volume of exports, allowing the country to enter into previously inaccessible markets

    2014-10-01

    This article looks at the way people determine the antecedent of a pronoun in sentence pairs, such as: Albert invited Ron to dinner. He spent hours cleaning the house. The experiment reported here is motivated by the idea that such judgments depend on reasoning about identity (e.g., the identity of the he who cleaned the house). Because the identity of an individual over time depends on the causal-historical path connecting the stages of the individual, the correct antecedent will also depend on causal connections. The experiment varied how likely it is that the event of the first sentence (e.g., the invitation) would cause the event of the second (the house cleaning) for each of the two individuals (the likelihood that if Albert invited Ron to dinner, this would cause Albert to clean the house, versus cause Ron to clean the house). Decisions about the antecedent followed causal likelihood. A mathematical model of causal identity accounted for most of the key aspects of the data from the individual sentence pairs.

  8. Diagnostic reasoning using qualitative causal models

    The application of expert systems to reasoning problems involving real-time data from plant measurements has been a topic of much research, but few practical systems have been deployed. One obstacle to wider use of expert systems in applications involving real-time data is the lack of adequate knowledge representation methodologies for dynamic processes. Knowledge bases composed mainly of rules have disadvantages when applied to dynamic processes and real-time data. This paper describes a methodology for the development of qualitative causal models that can be used as knowledge bases for reasoning about process dynamic behavior. These models provide a systematic method for knowledge base construction, considerably reducing the engineering effort required. They also offer much better opportunities for verification and validation of the knowledge base, thus increasing the possibility of the application of expert systems to reasoning about mission critical systems. Starting with the Signed Directed Graph (SDG) method that has been successfully applied to describe the behavior of diverse dynamic processes, the paper shows how certain non-physical behaviors that result from abstraction may be eliminated by applying causal constraint to the models. The resulting Extended Signed Directed Graph (ESDG) may then be compiled to produce a model for use in process fault diagnosis. This model based reasoning methodology is used in the MOBIAS system being developed by Duke Power Company under EPRI sponsorship. 15 refs., 4 figs

    The perceptual upright is thought to be constructed by the central nervous system (CNS) as a vector sum; by combining estimates on the upright provided by the visual system and the body's inertial sensors with prior knowledge that upright is usually above the head. Recent findings furthermore show that the weighting of the respective sensory signals is proportional to their reliability, consistent with a Bayesian interpretation of a vector sum (Forced Fusion, FF). However, violations of FF have also been reported, suggesting that the CNS may rely on a single sensory system (Cue Capture, CC), or choose to process sensory signals based on inferred signal causality (Causal Inference, CI). We developed a novel alternative-reality system to manipulate visual and physical tilt independently. We tasked participants (n = 36) to indicate the perceived upright for various (in-)congruent combinations of visual-inertial stimuli, and compared models based on their agreement with the data. The results favor the CI model over FF, although this effect became unambiguous only for large discrepancies (±60°). We conclude that the notion of a vector sum does not provide a comprehensive explanation of the perception of the upright, and that CI offers a better alternative.

    In AdS/CFT, the fine grained entropy of a boundary region is dual to the area of an extremal surface X in the bulk. It has been proposed that the area of a certain ‘causal surface’ C — i.e. the ‘causal holographic information’ (CHI) — corresponds to some coarse-grained entropy in the boundary theory. We construct two kinds of counterexamples that rule out various possible duals, using (1) vacuum rigidity and (2) thermal quenches. This includes the ‘one-point entropy’ proposed by Kelly and Wall, and a large class of related procedures. Also, any coarse-graining that fixes the geometry of the bulk ‘causal wedge’ bounded by C, fails to reproduce CHI. This is in sharp contrast to the holographic entanglement entropy, where the area of the extremal surface X measures the same information that is found in the ‘entanglement wedge’ bounded by X.

  13. The discourse of causal explanations in school science

    Slater, Tammy Jayne Anne

    Researchers and educators working from a systemic functional linguistic perspective have provided a body of work on science discourse which offers an excellent starting point for examining the linguistic aspects of the development of causal discourse in school science, discourse which Derewianka (1995) claimed is critical to success in secondary school. No work has yet described the development of causal language by identifying the linguistic features present in oral discourse or by comparing the causal discourse of native and non-native (ESL) speakers of English. The current research responds to this gap by examining the oral discourse collected from ESL and non-ESL students at the primary and high school grades. Specifically, it asks the following questions: (1) How do the teachers and students in these four contexts develop causal explanations and their relevant taxonomies through classroom interactions? (2) What are the causal discourse features being used by the students in these four contexts to construct oral causal explanations? The findings of the social practice analysis showed that the teachers in the four contexts differed in their approaches to teaching, with the primary school mainstream teacher focusing largely on the hands-on practice , the primary school ESL teacher moving from practice to theory, the high school mainstream teacher moving from theory to practice, and the high school ESL teacher relying primarily on theory. The findings from the quantitative, small corpus approach suggest that the developmental path of cause which has been identified in the writing of experts shows up not only in written texts but also in the oral texts which learners construct. Moreover, this move appears when the discourse of high school ESL and non-ESL students is compared, suggesting a developmental progression in the acquisition of these features by these students. The findings also reveal that the knowledge constructed, as shown by the concept maps created

    Full Text Available The article focuses on the symbolic meaning of Russian ringing of bell in the Russian discourse. According to Lotman’s definition of symbol, it has dual nature: an invariant essence and its modification in relation to the cultural context. The article introduces informative and linguistic modifications of the bell topic in the Russian poetic discourse of the 19th, the 20th and the beginning of the 21st century. The author of the article provides the detailed analysis of such discursive descriptions of bell ringing as the ringing of church bells and alarm . The author arrives at the conlusion that the alarm topic prevails in contemporary poetry and this indicates the state of public dissatisfaction. In the 19th and the 20th centuries lexemes the ringing of church bells and alarm were used literally, but in the 21st century lexeme alarm acquires metaphorical meaning of call for blood.

  17. Disease causality extraction based on lexical semantics and document-clause frequency from biomedical literature.

    Lee, Dong-Gi; Shin, Hyunjung

    2017-05-18

    Recently, research on human disease network has succeeded and has become an aid in figuring out the relationship between various diseases. In most disease networks, however, the relationship between diseases has been simply represented as an association. This representation results in the difficulty of identifying prior diseases and their influence on posterior diseases. In this paper, we propose a causal disease network that implements disease causality through text mining on biomedical literature. To identify the causality between diseases, the proposed method includes two schemes: the first is the lexicon-based causality term strength, which provides the causal strength on a variety of causality terms based on lexicon analysis. The second is the frequency-based causality strength, which determines the direction and strength of causality based on document and clause frequencies in the literature. We applied the proposed method to 6,617,833 PubMed literature, and chose 195 diseases to construct a causal disease network. From all possible pairs of disease nodes in the network, 1011 causal pairs of 149 diseases were extracted. The resulting network was compared with that of a previous study. In terms of both coverage and quality, the proposed method showed outperforming results; it determined 2.7 times more causalities and showed higher correlation with associated diseases than the existing method. This research has novelty in which the proposed method circumvents the limitations of time and cost in applying all possible causalities in biological experiments and it is a more advanced text mining technique by defining the concepts of causality term strength.

    2017-12-01

    Full Text Available One of the distinctive features of Russia’s confrontation with the West over the 2014-2016 period is the intensification of Russian propaganda both in foreign countries and within the state. Lithuania, whose relations with a major neighbour were not normalized, and which openly supported Ukraine’s position, attracted the additional attention of Russian mass media in which an incitement to anti- Lithuanian moods was bolstered. In this case, it is endeavoured to generally describe how the mass media (television and newspapers played a role in contriving a social construct and ascertain the Lithuanian quantitative characteristics which are presented in Russian mass media. Referring to the analysis, one can distinguish three prevailing negative images of Lithuania - that is, Russophobic and anti-Russian; a falsifier of history; and a failing and non-influential state. These images, being consistently and purposefully exploited in Russian information space, almost with no alternative sources, turned into undeniable truth for the majority of Russian citizens. This provides the Kremlin with vast possibilities of manipulation in constructing the tactics and strategy of geopolitical instability. On the other hand, one should not forget that such a negative picture of Lithuania serves as a way in which Russian society justifies Putin’s political system and demonstrates its superiority over the values of the Western world.

  1. Spectral dimension in causal set quantum gravity

    Eichhorn, Astrid; Mizera, Sebastian

    2014-01-01

    We evaluate the spectral dimension in causal set quantum gravity by simulating random walks on causal sets. In contrast to other approaches to quantum gravity, we find an increasing spectral dimension at small scales. This observation can be connected to the nonlocality of causal set theory that is deeply rooted in its fundamentally Lorentzian nature. Based on its large-scale behaviour, we conjecture that the spectral dimension can serve as a tool to distinguish causal sets that approximate manifolds from those that do not. As a new tool to probe quantum spacetime in different quantum gravity approaches, we introduce a novel dimensional estimator, the causal spectral dimension, based on the meeting probability of two random walkers, which respect the causal structure of the quantum spacetime. We discuss a causal-set example, where the spectral dimension and the causal spectral dimension differ, due to the existence of a preferred foliation. (paper)

    1984-01-01

    The differential-difference (DD) motion equations of the causal nonrelativistic classical electrodynamics developed by the author in 1975 are shown to possess only nonrunaway, causal solutions with no discontinuities in particle velocity or position. As an example, the DD equation solution for the problem of an electromagnetic shock incident on an initially stationary charged particle is contrasted with the standard Abraham-Lorentz equation solution. The general Cauchy problem for these DD motion equations is discussed. In general, in order to uniquely determine a solution, the initial data must be more detailed than the standard Cauchy data of initial position and velocity. Conditions are given under which the standard Cauchy data will determine the DD equation solutions to sufficient practical accuracy

    In quantum mechanics, the state is prepared by a measurement on a space-like surface sigma. What is that determines the surface sigma on which the measurement prepares the state It is considered either a mechanism proper to the measuring process (apparatus) or a universal property of space-time. In the former case, problems arise, concerning causality or conservation of probability due to that the velocity of reduction of wave-packet is considered to exceed the light velocity. The theory of finite degree of freedom proposed previously belongs to the latter case. In this theory, the surface sigma is restricted to the hyper-plane perpendicular to a universal time-like vector governing causal relations. We propose an experiment to discriminate between the above-mentioned two cases and to test the existence of the universal time-like vector. (auth.)

    Full Text Available The article is devoted to the research of Russian initiatives concerning its participation in international system of Internet governance. In the research, conceptual and theoretic basis for participation of state governments in Internet governance is given, academic discourse of this issue is assessed, the review of main Russian initiatives made from 2005 (since the second stage of the World Summit on Information Society till the present day is carried out. The conclusion is made that the most successful Internet governance initiative of Russia is the implementation of cyrillic top level domains. Much less successful are Russian attempts to reconstruct existing organizational structure of Internet governance. Russian policy is assessed as a policy of preferring loud statements and PR rather than real influence on development of Internet technologies. Russia consideres Internet as political resource and tries to increase its influence on decision making process on a political, not operational level of Internet governance. The author states that federal government of the United States of America has fully lost the control on the domain name systems. These functions are going to be given to the private sector, while ICANN, which was established according to the Memorandum of Understanding/Joint Project Agreement with U.S. Department of Commerce, is becoming a truly independent international organization. Considering this, the author comes to the conclusion that political transformations for the sake of Russia are already made. He also forecast that next initiatives of Russia will be directed to the segmentation of the Internet.

When a metamaterial is built and illuminated with a coherent extraordinary laser beam, the stationary pattern of light propagation inside the metamaterial may be treated as a collection of particle world lines, which represents a complete ‘history’ of this 2 + 1-dimensional space–time. While this model may be used to build interesting space–time analogs, such as metamaterial ‘black holes’ and a metamaterial ‘big bang’, it lacks causality: since light inside the metamaterial may propagate back and forth along the ‘timelike’ spatial coordinate, events in the ‘future’ may affect events in the ‘past’. Here we demonstrate that a more sophisticated metamaterial model may fix this deficiency via breaking the mirror and temporal (PT) symmetries of the original model and producing one-way propagation along the ‘timelike’ spatial coordinate. The resulting 2 + 1-dimensional Minkowski space–time appears to be causal. This scenario may be considered as a metamaterial model of the Wheeler–Feynman absorber theory of causality. (paper)

  19. THE CAUSAL ANALYSIS / DIAGNOSIS DECISION ...

    Science.gov (United States)

    CADDIS is an on-line decision support system that helps investigators in the regions, states and tribes find, access, organize, use and share information to produce causal evaluations in aquatic systems. It is based on the US EPA's Stressor Identification process which is a formal method for identifying causes of impairments in aquatic systems. CADDIS 2007 increases access to relevant information useful for causal analysis and provides methods and tools that practitioners can use to analyze their own data. The new Candidate Cause section provides overviews of commonly encountered causes of impairments to aquatic systems: metals, sediments, nutrients, flow alteration, temperature, ionic strength, and low dissolved oxygen. CADDIS includes new Conceptual Models that illustrate the relationships from sources to stressors to biological effects. An Interactive Conceptual Model for phosphorus links the diagram with supporting literature citations. The new Analyzing Data section helps practitioners analyze their data sets and interpret and use those results as evidence within the USEPA causal assessment process. Downloadable tools include a graphical user interface statistical package (CADStat), and programs for use with the freeware R statistical package, and a Microsoft Excel template. These tools can be used to quantify associations between causes and biological impairments using innovative methods such as species-sensitivity distributions, biological inferenc

  20. Causal structure of analogue spacetimes

    The so-called 'analogue models of general relativity' provide a number of specific physical systems, well outside the traditional realm of general relativity, that nevertheless are well-described by the differential geometry of curved spacetime. Specifically, the propagation of perturbations in these condensed matter systems is described by 'effective metrics' that carry with them notions of 'causal structure' as determined by an exchange of quasi-particles. These quasi-particle-induced causal structures serve as specific examples of what can be done in the presence of a Lorentzian metric without having recourse to the Einstein equations of general relativity. (After all, the underlying analogue model is governed by its own specific physics, not necessarily by the Einstein equations.) In this paper we take a careful look at what can be said about the causal structure of analogue spacetimes, focusing on those containing quasi-particle horizons, both with a view to seeing what is different from standard general relativity, and what the similarities might be. For definiteness, and because the physics is particularly simple to understand, we will phrase much of the discussion in terms of acoustic disturbances in moving fluids, where the underlying physics is ordinary fluid mechanics, governed by the equations of traditional hydrodynamics, and the relevant quasi-particles are the phonons. It must however be emphasized that this choice of example is only for the sake of pedagogical simplicity and that our considerations apply generically to wide classes of analogue spacetimes

  1. Obesity and infection: reciprocal causality.

    Associations between different infectious agents and obesity have been reported in humans for over thirty years. In many cases, as in nosocomial infections, this relationship reflects the greater susceptibility of obese individuals to infection due to impaired immunity. In such cases, the infection is not related to obesity as a causal factor but represents a complication of obesity. In contrast, several infections have been suggested as potential causal factors in human obesity. However, evidence of a causal linkage to human obesity has only been provided for adenovirus 36 (Adv36). This virus activates lipogenic and proinflammatory pathways in adipose tissue, improves insulin sensitivity, lipid profile and hepatic steatosis. The E4orf1 gene of Adv36 exerts insulin senzitizing effects, but is devoid of its pro-inflammatory modalities. The development of a vaccine to prevent Adv36-induced obesity or the use of E4orf1 as a ligand for novel antidiabetic drugs could open new horizons in the prophylaxis and treatment of obesity and diabetes. More experimental and clinical studies are needed to elucidate the mutual relations between infection and obesity, identify additional infectious agents causing human obesity, as well as define the conditions that predispose obese individuals to specific infections.

    This is an elementary introduction to causal inference in economics written for readers familiar with machine learning methods. The critical step in any causal analysis is estimating the counterfactual-a prediction of what would have happened in the absence of the treatment. The powerful techniques used in machine learning may be useful for developing better estimates of the counterfactual, potentially improving causal inference.

    2011-01-01

    Full Text Available The publication is devoted to the history of one of the greatest concepts of tectonics of Asia, that has been widely accepted and yet obliterated with time, while the splendors of this concept are doubtful. Numerous citations in the Russian papers to «The Face of the Earth» by Edward Suess and the fact that he was elected a Corresponding Member of the Imperial Saint Petersburg Academy of Sciences clearly demonstrate how highly Suess’s contribution to studies of the structure and geological evolution of Asia was valued by the Russian geological community. Suess’s letters to Vladimir A. Obruchev give evidence how close and productive the relationship between Edward Suess and the Russian researchers was in the late 19th and the early 20th centuries and also illustrate how the great tectonic concept of Asia [Suess, 1908] was born and developed. The idea of centrifugal propagation of tectonic waves of the Altaids from a continental node located somewhere in Siberia was mainly inspired by Suess’s profound scientific intuition. The idea matured after Edward Suess got acquainted with Ivan D. Chersky’s paper [Черский, 1886] that greatly facilitated in shaping and improving this idea. It was mailed to Suess by Vladimir A. Obruchev who translated the paper, attached his own map and provided explanations to Chersky’s ideas. The available historical documents suggest that Vladimir A. Obruchev facilitated communication between the Russian geologists, on the one side, and Edward Suess and other Austrian geologists who conducted geological studies in Asia, on the other side. Being actively involved in exchange of publications and cooperation in field data processing, Edward Suess was aware of all the details of the Russian geological studies.In addition to the concept of tectonic arcs of the Altaids and descriptions of main geological structures located in Northern Asia and China, Edward Suess adopted a concept of disjunctive dislocations

    2016-12-01

    Full Text Available This paper empirically analyses the determinants of foreign direct investment inflows into the Russian regions. This problem has become highly relevant for the necessary modernization of the Russian economy after the recent economic slowdown and sharp decrease in budget revenues. The authors model foreign direct investment flows with the use of the gravity approach according to which investment flows are positively correlated with the size of the investor’s country as well as the size of the recipient region and are negatively correlated with the distance between investor and recipient. The empirical analysis is based on a constructed database consisting of the foreign direct investment flows from 179 investor countries into 78 Russian regions for the period 2006–2013. The authors apply the Poisson Pseudo Maximum Likelihood method and identify the following factors determining foreign direct investment inflows into the Russian economy: the gross domestic product of the investor’s country, the gross domestic product per capita in the recipient region, the distance from the investor to Moscow, the openness of the region, the economic situation in the region, the innovative capacity of the region and the foreign direct investment of the previous period. Interestingly, the distance from the recipient region to Moscow matters for the regions in the western part of Russia (relatively close to Moscow but is not significant for the regions in the eastern part (remote regions.

    2010-01-01

    In this article, I argue that norms and customs, despite frequently being described as being causes of behavior in the social sciences and ordinary conversation, cannot really cause behavior. Terms like "norms" and the like seem to refer to philosophically disreputable disjunctive properties. More problematically, even if they do not, or even if there can be disjunctive properties after all, I argue that norms and customs still cannot cause behavior. The social sciences would be better off without referring to properties like norms and customs as if they could be causal.

    2017-12-01

    Full Text Available This article examines the commodification of Russian in Finland, where recent decades have seen a sharp rise in the size of the Russian-speaking population and the number of tourists from Russia. We particularly consider the use of Russian in the fields of traditional and medical tourism, education, and culture - all of them areas where Russian tourists show a strong preference for services in their native language. The need to provide a variety of services in Russian means that proficiency in Russian is a sig-nificant asset on the job market, both for immigrants and for the relatively small number of Finns who can speak the language. We also note that there is considerable demand among Russian-speaking parents in Fin-land for educational services to supplement their children’s school education.

    The authors outline a cognitive and computational account of causal learning in children. They propose that children use specialized cognitive systems that allow them to recover an accurate "causal map" of the world: an abstract, coherent, learned representation of the causal relations among events. This kind of knowledge can be perspicuously understood in terms of the formalism of directed graphical causal models, or Bayes nets.

Works on the dictionary are based on Gramatyka konfrontatywna bułgarsko-polska (Bulgarian-Polish confrontative grammar and the proposed there semantic-oriented interlanguage. Two types of classifiers have been introduced into the dictionary: classic and semantic. The trilingual dictionary will present a consistent and homogeneous set of facts of grammar and semantics. The Authors point out that in a traditional dictionary it is not clear for example whether aspect should be understood as imperfective / perfective form of a verb or as its meaning. Therefore in the dictionary forms and meaning are separated in a regular way. Imperfective verb form has two meanings: state and configuration of states and events culminating in state. Also perfective verb form has two meanings: event and configuration of states and events culminating in event. These meanings are described by the semantic classifiers, respectively, state and event, state1 and event1. The way of describing language units, mentioned in the article, gives a possibility to present language material (Polish, Bulgarian, Russian in any required order, hence the article’s title.

  15. Causal mediation analysis with multiple causally non-ordered mediators.

    Taguri, Masataka; Featherstone, John; Cheng, Jing

    In many health studies, researchers are interested in estimating the treatment effects on the outcome around and through an intermediate variable. Such causal mediation analyses aim to understand the mechanisms that explain the treatment effect. Although multiple mediators are often involved in real studies, most of the literature considered mediation analyses with one mediator at a time. In this article, we consider mediation analyses when there are causally non-ordered multiple mediators. Even if the mediators do not affect each other, the sum of two indirect effects through the two mediators considered separately may diverge from the joint natural indirect effect when there are additive interactions between the effects of the two mediators on the outcome. Therefore, we derive an equation for the joint natural indirect effect based on the individual mediation effects and their interactive effect, which helps us understand how the mediation effect works through the two mediators and relative contributions of the mediators and their interaction. We also discuss an extension for three mediators. The proposed method is illustrated using data from a randomized trial on the prevention of dental caries.

    2011-02-01

    Full Text Available This study explores English and Russian speech verbs with phone prepositional phrases (PPs. It investigates two hypotheses: 1 A phone PP produces an independent construction and 2 A phone PP can be freely added to any speech verb. Two constructions in English and two constructions in Russian are used as the material for the analysis. In both languages I explore a neutral phone construction and compare it with a construction meaning ‘speak into the phone’. I present a new method – statistical profiling, that explores which words occur in a slot of a construction most frequently and how that frequency list for a slot is changed if another slot is filled. This paper shows that English on the phone phrase can freely be added to any speech and sound verb, while other phone PPs produce different phone constructions.

    The paper describes the Soviet experience preserved in Russia and related to the strategy of nuclear knowledge preservation in period of fast nuclear energy deployment. It's also discusses the problems of 80-90ies: 'gap' between generations, loss of the experimental base, ageing of scientific teams, weakened governmental support, etc. Obviously resumed positive development of the Russian nuclear energy in the last years, as well as expectation of the 'Second Nuclear Era' of large-scale nuclear energy use in the country, has made the elimination of NKM defects and the development of human resources one of the most important and vital prerequisites of the further nuclear development. The paper considers the measures taken in this regard by the Russian nuclear industry, including international cooperation

    Results on rigorous construction of quantum fields on the hypercubic lattice Z 4 considered as a lattice in the Minkowski space R 4 are presented. Two associated fields are constructed: The first one having on the lattice points of Z 4 is causal and Poincare invariant in the discrete sense. The second one is an interpolating field over R 4 which is pointlike, translationally covariant and spectral in such a manner that the 'real' lattices field is the restriction of the interpolating field to Z 4 . Furthermore, results on a rigorous perturbation theory of such fields are mentioned

    This document concerns the systems, design, and operations of the graphite-moderated, boiling, water-cooled, channel-type (RBMK) reactors located in the former Soviet Union (FSU). The Russian Academy of Sciences Nuclear Safety Institute (NSI) in Moscow, Russia, researched specific technical questions that were formulated by the Pacific Northwest Laboratory (PNL) and provided detailed technical answers to those questions. The Russian response was prepared in English by NSI in a question-and-answer format. This report presents the results of that technical exchange in the context they were received from the NSI organization. Pacific Northwest Laboratory is generating this document to support the US Department of Energy (DOE) community in responding to requests from FSU states, which are seeking Western technological and financial assistance to improve the safety systems of the Russian-designed reactors. This report expands upon information that was previously available to the United States through bilateral information exchanges, international nuclear society meetings, International Atomic Energy Agency (IAEA) reactor safety programs, and Research and Development Institute of Power Engineering (RDIPE) reports. The response to the PNL questions have not been edited or reviewed for technical consistency or accuracy by PNL staff or other US organizations, but are provided for use by the DOE community in the form they were received

  3. The Functions of Danish Causal Conjunctions

    Directory of Open Access Journals (Sweden)

    Rita Therkelsen

    2004-01-01

    Full Text Available In the article I propose an analysis of the Danish causal conjunctions fordi, siden and for based on the framework of Danish Functional Grammar. As conjunctions they relate two clauses, and their semantics have in common that it indicates a causal relationship between the clauses. The causal conjunctions are different as far as their distribution is concerned; siden conjoins a subordinate clause and a main clause, for conjoins two main clauses, and fordi is able to do both. Methodologically I have based my analysis on these distributional properties comparing siden and fordi conjoining a subordinate and a main clause, and comparing for and fordi conjoining two main clauses, following the thesis that they would establish a causal relationship between different kinds of content. My main findings are that fordi establishes a causal relationship between the events referred to by the two clauses, and the whole utterance functions as a statement of this causal relationship. Siden presupposes such a general causal relationship between the two events and puts forward the causing event as a reason for assuming or wishing or ordering the caused event, siden thus establishes a causal relationship between an event and a speech act. For equally presupposes a general causal relationship between two events and it establishes a causal relationship between speech acts, and fordi conjoining two main clauses is able to do this too, but in this position it also maintains its event-relating ability, the interpretation depending on contextual factors.

  4. Space and time in perceptual causality

    Directory of Open Access Journals (Sweden)

    Benjamin Straube

    2010-04-01

    Full Text Available Inferring causality is a fundamental feature of human cognition that allows us to theorize about and predict future states of the world. Michotte suggested that humans automatically perceive causality based on certain perceptual features of events. However, individual differences in judgments of perceptual causality cast doubt on Michotte’s view. To gain insights in the neural basis of individual difference in the perception of causality, our participants judged causal relationships in animations of a blue ball colliding with a red ball (a launching event while fMRI-data were acquired. Spatial continuity and temporal contiguity were varied parametrically in these stimuli. We did not find consistent brain activation differences between trials judged as caused and those judged as non-caused, making it unlikely that humans have universal instantiation of perceptual causality in the brain. However, participants were slower to respond to and showed greater neural activity for violations of causality, suggesting that humans are biased to expect causal relationships when moving objects appear to interact. Our participants demonstrated considerable individual differences in their sensitivity to spatial and temporal characteristics in perceiving causality. These qualitative differences in sensitivity to time or space in perceiving causality were instantiated in individual differences in activation of the left basal ganglia or right parietal lobe, respectively. Thus, the perception that the movement of one object causes the movement of another is triggered by elemental spatial and temporal sensitivities, which themselves are instantiated in specific distinct neural networks.

    Full Text Available The article deals the issue of the positions of Russian capital in Latvian market. The paper aims to estimate the volume and dynamics of Russian capital inflows into Latvia in compliance with Russian economic interests; to identify key sectors of Latvian economy that Russian capital is interested to invest in; to systemize information concerning Russian firms investing in Latvia; to assess the role of Russian capital in Latvian economy in comparison with other foreign investors; to propose author’s view on challenges and perspectives of Latvian-Russian investment cooperation in the situation of economic sanctions and geo-political conflict in east Ukraine. The author underlines that at the end of 2013, investments of Russian business to Latvia constituted about 5.0% of the total FDI stock and by that time Russia was the 7th largest investor with 0.5 bln euro of capital invested. The main sectors of Russian interests in Latvia are - gas supply, transport communications (transit corridors, banking and real estate. The article concludes that though the future of Russian-Latvian economic relations in the short-run is on a substantial pressure of geopolitical factors, the economic interests in mutual investment relations will prevail in the long-run perspectives.

  6. Confounding factors in determining causal soil moisture-precipitation feedback

    Science.gov (United States)

    Tuttle, Samuel E.; Salvucci, Guido D.

    2017-07-01

    Identification of causal links in the land-atmosphere system is important for construction and testing of land surface and general circulation models. However, the land and atmosphere are highly coupled and linked by a vast number of complex, interdependent processes. Statistical methods, such as Granger causality, can help to identify feedbacks from observational data, independent of the different parameterizations of physical processes and spatiotemporal resolution effects that influence feedbacks in models. However, statistical causal identification methods can easily be misapplied, leading to erroneous conclusions about feedback strength and sign. Here, we discuss three factors that must be accounted for in determination of causal soil moisture-precipitation feedback in observations and model output: seasonal and interannual variability, precipitation persistence, and endogeneity. The effect of neglecting these factors is demonstrated in simulated and observational data. The results show that long-timescale variability and precipitation persistence can have a substantial effect on detected soil moisture-precipitation feedback strength, while endogeneity has a smaller effect that is often masked by measurement error and thus is more likely to be an issue when analyzing model data or highly accurate observational data.

  7. Causal diagrams in systems epidemiology

    Directory of Open Access Journals (Sweden)

    Joffe Michael

    2012-03-01

    Full Text Available Abstract Methods of diagrammatic modelling have been greatly developed in the past two decades. Outside the context of infectious diseases, systematic use of diagrams in epidemiology has been mainly confined to the analysis of a single link: that between a disease outcome and its proximal determinant(s. Transmitted causes ("causes of causes" tend not to be systematically analysed. The infectious disease epidemiology modelling tradition models the human population in its environment, typically with the exposure-health relationship and the determinants of exposure being considered at individual and group/ecological levels, respectively. Some properties of the resulting systems are quite general, and are seen in unrelated contexts such as biochemical pathways. Confining analysis to a single link misses the opportunity to discover such properties. The structure of a causal diagram is derived from knowledge about how the world works, as well as from statistical evidence. A single diagram can be used to characterise a whole research area, not just a single analysis - although this depends on the degree of consistency of the causal relationships between different populations - and can therefore be used to integrate multiple datasets. Additional advantages of system-wide models include: the use of instrumental variables - now emerging as an important technique in epidemiology in the context of mendelian randomisation, but under-used in the exploitation of "natural experiments"; the explicit use of change models, which have advantages with respect to inferring causation; and in the detection and elucidation of feedback.

  9. Probabilistic causality and radiogenic cancers

    International Nuclear Information System (INIS)

    Groeer, P.G.

    1986-01-01

    A review and scrutiny of the literature on probability and probabilistic causality shows that it is possible under certain assumptions to estimate the probability that a certain type of cancer diagnosed in an individual exposed to radiation prior to diagnosis was caused by this exposure. Diagnosis of this causal relationship like diagnosis of any disease - malignant or not - requires always some subjective judgments by the diagnostician. It is, therefore, illusory to believe that tables based on actuarial data can provide objective estimates of the chance that a cancer diagnosed in an individual is radiogenic. It is argued that such tables can only provide a base from which the diagnostician(s) deviate in one direction or the other according to his (their) individual (consensual) judgment. Acceptance of a physician's diagnostic judgment by patients is commonplace. Similar widespread acceptance of expert judgment by claimants in radiation compensation cases does presently not exist. Judicious use of the present radioepidemiological tables prepared by the Working Group of the National Institutes of Health or of updated future versions of similar tables may improve the situation. 20 references

    2006-01-01

    In this paper we tackle the issue of causality in quantum gravity, in the context of 3d spin foam models. We identify the correct procedure for implementing the causality/orientation dependence restriction that reduces the path integral for BF theory to that of quantum gravity in first order form. We construct explicitly the resulting causal spin foam model. We then add matter degrees of freedom to it and construct a causal spin foam model for 3d quantum gravity coupled to matter fields. Finally, we show that the corresponding spin foam amplitudes admit a natural approximation as the Feynman amplitudes of a noncommutative quantum field theory, with the appropriate Feynman propagators weighting the lines of propagation, and that this effective field theory reduces to the usual quantum field theory in flat space in the no-gravity limit

    Full text of publication follows: On September 1, 2000, the United States and Russia signed a historic agreement to each dispose of 34 tons of excess weapons plutonium by 2025, or sooner if possible. The agreement was conditional on international financing of the Russian program. The parties are now attempting to establish a specific program for disposition of the Russian plutonium and to secure commitments for international financing of the Russian program. In the United States, efforts are moving forward to design, license, and construct the necessary facilities for its disposition program. With the assistance of France and Germany, efforts are moving forward in Russia to plan and design appropriate reactor modifications as well as the needed facilities for plutonium conversion and mixed-oxide fabrication. Japan and Canada are also participants in the Russian disposition program. This panel session will review the status of actions taken to bring this agreement to fruition. (authors)

    Emphasizing causation as a functional relationship between variables that describe objects, Linear Causal Modeling with Structural Equations integrates a general philosophical theory of causation with structural equation modeling (SEM) that concerns the special case of linear causal relations. In addition to describing how the functional relation concept may be generalized to treat probabilistic causation, the book reviews historical treatments of causation and explores recent developments in experimental psychology on studies of the perception of causation. It looks at how to perceive causal

    Full Text Available On December 25, 2014 it would be twenty-one year since the Constitution of the Russian Federation was adopted on the national referendum on December 12, 1993. During this time, almost all constitutional provisions are implemented. The key point of course was the judicial reform in Russia, launched simultaneously with the adoption of Constitution of the Russian Federation. Adopted the new Civil Procedural Code, Criminal Procedural Code, Arbitration Procedural Code of the Russian Federation, Federal Constitutional Law "On the Constitutional Court of the Russian Federation", Federal Constitutional Law "On the courts of general jurisdiction in Russia", Federal Constitutional Law "On the Supreme Court of the Russian Federation". However, during twenty-one year of Russian Constitution work, the question on establishment of administrative courts in our country has not been resolved. Merger of the Supreme Court and the Supreme Arbitration Court of the Russian Federation, which happened in the year 2014, also shown the need to resolve the status of administrative courts in Russia. Previously submitted to the State Duma of the Federal Assembly of the Russian Federation the draft of the Federal Constitutional Law "On the Federal Administrative Courts in the Russian Federation" and is on the revision, which does not correspond to changes in the judicial system of the Russian Federation. Despite the failure of the Federal Constitutional Law "On the Federal Administrative Courts in the Russian Federation", in the opinion of the author, and it should be called that way, it Russia has already developed an own model of the Russian administrative justice, which is very specific.

    Bombelli, L.; Lee, J.; Meyer, D.; Sorkin, R.D.

    1987-01-01

    We propose that space-time at the smallest scales is in reality a causal set: a locally finite set of elements endowed with a partial order corresponding to the macroscopic relation that defines past and future. We explore how a Lorentzian manifold can approximate a causal set, noting in particular that the thereby defined effective dimensionality of a given causal set can vary with length scale. Finally, we speculate briefly on the quantum dynamics of causal sets, indicating why an appropriate choice of action can reproduce general relativity in the classical limit

    2011-01-01

    In addition to identifying individual objects in the world, the visual system must also characterize the relationships between objects, for instance when objects occlude one another or cause one another to move. Here we explored the relationship between perceived causality and occlusion. Can one perceive causality in an occluded location? In several experiments, observers judged whether a centrally presented event involved a single object passing behind an occluder, or one object causally launching another (out of view and behind the occluder). With no additional context, the centrally presented event was typically judged as a non-causal pass, even when the occluding and disoccluding objects were different colors--an illusion known as the 'tunnel effect' that results from spatiotemporal continuity. However, when a synchronized context event involved an unambiguous causal launch, participants perceived a causal launch behind the occluder. This percept of an occluded causal interaction could also be driven by grouping and synchrony cues in the absence of any explicitly causal interaction. These results reinforce the hypothesis that causality is an aspect of perception. It is among the interpretations of the world that are independently available to vision when resolving ambiguity, and that the visual system can 'fill in' amodally.

  20. Quantum retrodiction and causality principle

    International Nuclear Information System (INIS)

    Shirokov, M.I.

    1994-01-01

    Quantum mechanics is factually a predictive science. But quantum retrodiction may also be needed, e.g., for the experimental verification of the validity of the Schroedinger equation for the wave function in the past if the present state is given. It is shown that in the retrodictive analog of the prediction the measurement must be replaced by another physical process called the retromeasurement. In this process, the reduction of a state vector into eigenvectors of a measured observable must proceed in the opposite direction of time as compared to the usual reduction. Examples of such processes are unknown. Moreover, they are shown to be forbidden by the causality principle stating that the later event cannot influence the earlier one. So quantum retrodiction seems to be unrealizable. It is demonstrated that the approach to the retrodiction given by S.Watanabe and F.Belinfante must be considered as an unsatisfactory ersatz of retrodicting. 20 refs., 3 figs

    A fixed highest criterial velocity (of light) in STR (special theory of relativity) is a convention for a layer of physical inquiry. QM (Quantum Mechanics) avoids action-at-a-distance using this concept, but accepts non-causality and action-at-a-distance in EPR (Einstein-Podolsky-Rosen-Paradox) entanglement experiments. Even in such allegedly [non-causal] processes, something exists processually in extension-motion, between the causal and the [non-causal]. If STR theoretically allows real-valued superluminal communication between EPR entangled particles, quantum processes become fully causal. That is, the QM world is sub-luminally, luminally and superluminally local-causal throughout, and the Law of Causality is ubiquitous in the micro-world. Thus, ''probabilistic causality'' is a merely epistemic term.

  3. The causal perturbation expansion revisited: Rescaling the interacting Dirac sea

    Finster, Felix; Grotz, Andreas

    2010-01-01

    The causal perturbation expansion defines the Dirac sea in the presence of a time-dependent external field. It yields an operator whose image generalizes the vacuum solutions of negative energy and thus gives a canonical splitting of the solution space into two subspaces. After giving a self-contained introduction to the ideas and techniques, we show that this operator is, in general, not idempotent. We modify the standard construction by a rescaling procedure giving a projector on the generalized negative-energy subspace. The resulting rescaled causal perturbation expansion uniquely defines the fermionic projector in terms of a series of distributional solutions of the Dirac equation. The technical core of the paper is to work out the combinatorics of the expansion in detail. It is also shown that the fermionic projector with interaction can be obtained from the free projector by a unitary transformation. We finally analyze the consequences of the rescaling procedure on the light-cone expansion.

    Full Text Available Sustainable development of administrative-territorial units (ATU refers to the main directions of Russian Federation state policy to ensure the security of the national economy to meet the vital needs of people and the preservation of such a possibility for the future generations. The article describes and analyzes the factors that have the most significant impact on the level of ATE development. The dynamics of the gross output of agriculture in Russia and its critical evaluation are presents. It was revealed that the development of the region is the basis of the national economy security. At present, the concept of “sustainable development” in Russia is relevant and the role of regions in the sustainable development of the Russian Federation is constantly increasing. Stability of self-financing of the regional economy is achieved through conducting effective fiscal, financial, credit, tax and price policy, establishment of equal inter-budgetary relations with the federal center, the development of the securities market, increasing the volume of exports. Conducted research allowed: to identify the main factors influencing the sustainable development of Russia regions. The reasons for the backlog of economy of the Smolensk region of the nationwide growth rate and direction of their elimination are examined. Formation of the forecast of domestic agriculture development in the period up to 2020 should be based on the priority position of the industry in the agricultural sector, which is determined by its decisive role in meeting the population’s needs for basic food products. Prospective volumes of production of major agricultural products are based on the need to meet the challenges provided by the Russian Federation Government Decree.

    Full text: Union, the issue of generation and accumulation of nuclear knowledge and human resources for realizing this knowledge in practice, have received strong governmental support, and were subject to strict control of the state. This policy, despite the well-known Russian difficulties related to the lag of computational base and complicated scientific and technical exchange with the West ('Iron Curtain'), in the 50-70's has made it possible both to solve the required defence tasks and ensure development of peaceful nuclear energy applications in the Soviet Union. The report briefly summarizes the main achievements in the field of nuclear knowledge management strategy in the period of fast nuclear energy deployment, which include: - establishment, on the base of the 'Uranium Project' founder institutions, of a series of nuclear science and engineering centers (Arzamas, Dimitrovgrad, Dubna, etc.), both within the nuclear branch and in the USSR and Soviet Republics' Academies of Science; - formation of scientific schools headed by eminent scientists, on the base of major nuclear energy issues, gathering creative teams with 'natural' nuclear knowledge transfer; - harmonious nuclear education system, including a large network of higher professional education institutions, which had a principal achievement - close relationship with the leading nuclear research centers; - creation of a regional centers' network intended for regular retraining of nuclear specialists; - creation and development of national centers for collecting, processing and evaluation of nuclear and other data (materials, thermal physics, etc.) necessary for nuclear engineering, as well as for development of algorithms and codes. Russian nuclear program as a whole, and KNM system in particular, received three severe crises in a short time period: - Chernobyl accident (1986); - restructuring of the political system (end of 80's - beginning of 90's); - collapse of the Soviet Union (1991).

  8. In defense of causal-formative indicators: A minority report.

    Bollen, Kenneth A; Diamantopoulos, Adamantios

    2017-09-01

    Causal-formative indicators directly affect their corresponding latent variable. They run counter to the predominant view that indicators depend on latent variables and are thus often controversial. If present, such indicators have serious implications for factor analysis, reliability theory, item response theory, structural equation models, and most measurement approaches that are based on reflective or effect indicators. Psychological Methods has published a number of influential articles on causal and formative indicators as well as launching the first major backlash against them. This article examines 7 common criticisms of these indicators distilled from the literature: (a) A construct measured with "formative" indicators does not exist independently of its indicators; (b) Such indicators are causes rather than measures; (c) They imply multiple dimensions to a construct and this is a liability; (d) They are assumed to be error-free, which is unrealistic; (e) They are inherently subject to interpretational confounding; (f) They fail proportionality constraints; and (g) Their coefficients should be set in advance and not estimated. We summarize each of these criticisms and point out the flaws in the logic and evidence marshaled in their support. The most common problems are not distinguishing between what we call causal-formative and composite-formative indicators, tautological fallacies, and highlighting issues that are common to all indicators, but presenting them as special problems of causal-formative indicators. We conclude that measurement theory needs (a) to incorporate these types of indicators, and (b) to better understand their similarities to and differences from traditional indicators.

    2005-01-01

    Recently (Garcia-Parrado and Senovilla 2003 Class. Quantum Grav. 20 625-64) the concept of causal mapping between spacetimes, essentially equivalent in this context to the chronological map defined in abstract chronological spaces, and the related notion of causal structure, have been introduced as new tools to study causality in Lorentzian geometry. In the present paper, these tools are further developed in several directions such as (i) causal mappings-and, thus, abstract chronological ones-do not preserve two levels of the standard hierarchy of causality conditions (however, they preserve the remaining levels as shown in the above reference), (ii) even though global hyperbolicity is a stable property (in the set of all time-oriented Lorentzian metrics on a fixed manifold), the causal structure of a globally hyperbolic spacetime can be unstable against perturbations; in fact, we show that the causal structures of Minkowski and Einstein static spacetimes remain stable, whereas that of de Sitter becomes unstable, (iii) general criteria allow us to discriminate different causal structures in some general spacetimes (e.g. globally hyperbolic, stationary standard); in particular, there are infinitely many different globally hyperbolic causal structures (and thus, different conformal ones) on R 2 (iv) plane waves with the same number of positive eigenvalues in the frequency matrix share the same causal structure and, thus, they have equal causal extensions and causal boundaries

    2014-09-01

    Full Text Available In this paper, we describe the R package mediation for conducting causal mediation analysis in applied empirical research. In many scientific disciplines, the goal of researchers is not only estimating causal effects of a treatment but also understanding the process in which the treatment causally affects the outcome. Causal mediation analysis is frequently used to assess potential causal mechanisms. The mediation package implements a comprehensive suite of statistical tools for conducting such an analysis. The package is organized into two distinct approaches. Using the model-based approach, researchers can estimate causal mediation effects and conduct sensitivity analysis under the standard research design. Furthermore, the design-based approach provides several analysis tools that are applicable under different experimental designs. This approach requires weaker assumptions than the model-based approach. We also implement a statistical method for dealing with multiple (causally dependent mediators, which are often encountered in practice. Finally, the package also offers a methodology for assessing causal mediation in the presence of treatment noncompliance, a common problem in randomized trials.

    This paper aims to show that a counterfactual approach to causation is not sufficient to provide a solution to the causal exclusion problem in the form of systematic overdetermination. Taking into account the truthmakers of causal counterfactuals provides a strong argument in favour of the identity of causes in situations of translevel, causation.

  20. Values and education: Russian perspective

    Directory of Open Access Journals (Sweden)

    Borytko Nikolai M.

    2005-01-01

    Full Text Available This article is about some lessons of the multi-cultural analysis of a joint Russian-British educational project. The analysis, based on the achievements of Russian pedagogical science, about the achievement of the most effective cross-cultural communication, can be listed among the outcomes of the project, along with the applied results, which consists in developing an educational management training program. The growth of innovation process and international contacts in education testifies to the fact that education culture is evolving toward a new quality. In the evolution/process, the basic needs of schools, teachers and education managers are identified and conceptualized. Sharing achievements and discoveries in professional growth should be kept in mind and that fulfilling the needs can only take place within the context of the cultural-pedagogic position inherent to an individual teacher, a group of teachers, or a school. From the point of view of cross-cultural analysis, the specifics lie in the inherent values and the level at which the activity is typically performed. This analysis equips the researcher with the criteria necessary for identifying the culture type dealt with. This latter can be used then as a tool for analyzing and designing innovations.

  1. Factors fragmenting the Russian Federation

    Energy Technology Data Exchange (ETDEWEB)

    Brown, E.

    1993-10-06

    This paper examines the factors that threaten the future of the Russian Federation (RF). The observations are based on a study that focused on eight republics: Mordova, Udmurtia, Tatarstan, Mari El, Bashkortostan, Kabardino-Balkaria, Buryatia, and Altay Republic. These republics were selected for their geographic and economic significance to the RF. Tatarstan, Bashkortostan, Udmurtia, and Mari El are located on important supply routes, such as the Volga River and the trans-Siberian railroad. Some of these republics are relatively wealthy, with natural resources such as oil (e.g., Tatarstan and Bashkortostan), and all eight republics play significant roles in the military-industrial complex. The importance of these republics to the RF contrasts to the relative insignificance of the independence-minded Northern Caucasus area. The author chose not to examine the Northern Caucasus region (except Kabardino-Balkaria) because these republics may have only a minor impact on the rest of the RF if they secede. Their impact would be minimized because they lie on the frontiers of the RF. Many Russians believe that {open_quotes}it might be best to let such a troublesome area secede.{close_quotes}

    2017-01-01

    Full Text Available The article revises an established view of Russian Revolution as two separate events - February Revolution and October Revolution. The author supports the concept of the «Great Russian Revolution», which unites these two events in a single process of revolutionary development. The author draws attention to the following advantages of the concept under consideration. First, it conceptualizes the revolution as a process contingent of a local and global historical context. In this sense, the revolution is presented as the transition of society to the modern stage of development, meaning the transition to modernity. Second, revolutionary events in Russia are considered from the point of view of the evolution of the spatial and socioeconomic distribution and rearrangement of key social groups: peasantry, elites, national and ethnic minorities. Third, it takes into account the personal factor in the revolutionary events, the influence of individual personalities on escalation or the reduction of socio-political tensions. Fourth, it draws attention to the fact that revolutions imply the use of various forms of political violence. Each revolution is characterized by a unique correlation of forms and intensity of political violence. Finally, it gives a normative assessment of the Revolution, encouraging a national discussion on the results and consequences of this great event.

    2015-01-01

    The role of education in the process of socioeconomic attainment is a topic of long standing interest to sociologists and economists. Recently there has been growing interest not only in estimating the average causal effect of education on outcomes such as earnings, but also in estimating how...... causal effects might vary over individuals or groups. In this paper we point out one of the under-appreciated hazards of seeking to estimate heterogeneous causal effects: conventional selection bias (that is, selection on baseline differences) can easily be mistaken for heterogeneity of causal effects....... This might lead us to find heterogeneous effects when the true effect is homogenous, or to wrongly estimate not only the magnitude but also the sign of heterogeneous effects. We apply a test for the robustness of heterogeneous causal effects in the face of varying degrees and patterns of selection bias...

  4. Repair of Partly Misspecified Causal Diagrams.

    2017-07-01

    Errors in causal diagrams elicited from experts can lead to the omission of important confounding variables from adjustment sets and render causal inferences invalid. In this report, a novel method is presented that repairs a misspecified causal diagram through the addition of edges. These edges are determined using a data-driven approach designed to provide improved statistical efficiency relative to de novo structure learning methods. Our main assumption is that the expert is "directionally informed," meaning that "false" edges provided by the expert would not create cycles if added to the "true" causal diagram. The overall procedure is cast as a preprocessing technique that is agnostic to subsequent causal inferences. Results based on simulated data and data derived from an observational cohort illustrate the potential for data-assisted elicitation in epidemiologic applications.

    We study the causality constraints on the structure of the Lorentz-antisymmetric component of the commutator of two conserved isovector currents between fermion states of equal momenta. We discuss the sum rules that follow from causality and scaling, using the recently introduced refined infinite-momentum technique. The complete set of sum rules is found to include the spin-dependent fixed-mass sum rules obtained from light-cone commutators. The causality and scaling restrictions on the structure of the electromagnetic equal-time commutators are discussed, and it is found, in particular, that causality requires the spin-dependent part of the matrix element for the time-space electromagnetic equal-time commutator to vanish identically. It is also shown, in comparison with the electromagnetic case, that the corresponding matrix element for the time-space isovector current equal-time commutator is required, by causality, to have isospin-antisymmetric tensor and scalar operator Schwinger terms

    The first nuclear power project in the Slovak Republic was launched in 1958 through close cooperation with the Russian nuclear industry. Since then the Slovak and Russian nuclear branches were never separated. Technical and economic performances of the NPP units constructed with participation of Russian specialists were and continue being one of the best globally. The culture of business and competence of ASE is based on about 40 years of experience in construction of 29 NPP power units abroad with 20 GW total capacity. ASE strives to present to the Customers line of NPP designs ready for implementation and well-developed network of the multi-functional alliances and JVs. Currently, large-scale NPP projects involve public-private partnership (PPP) more and more. ASE development vision is to flexibly conform to Customers' requirements and needs and to diversify in related segments of EPC-business, namely designing, manufacturing, electric power trade, etc. Systematical approach to the fostering of mutual relations under the new economic conditions and nuclear renaissance, the Slovak-Russian cooperation in NPP engineering, manufacturing and construction are once again promising and long-term oriented.

    A fixed highest criterial velocity (of light) in STR (special theory of relativity) is a convention for a layer of physical inquiry. QM (Quantum Mechanics) avoids action-at-a-distance using this concept, but accepts non-causality and action-at-a-distance in EPR (Einstein-Podolsky-Rosen-Paradox) entanglement experiments. Even in such allegedly non-causal processes, something exists processually in extension-motion, between the causal and the non-causal. If STR theoretically allows real-valued superluminal communication between EPR entangled particles, quantum processes become fully causal. That

    2002-01-01

    Treatment of spent Russian fuel using a Melt-Dilute (MD) process is proposed to consolidate fuel assemblies into a form that is proliferation resistant and provides critically safety under storage and disposal configurations. Russian fuel elements contain a variety of fuel meat and cladding materials. The Melt-Dilute treatment process was initially developed for aluminum-based fuels so additional development is needed for several cladding and fuel meat combinations in the Russian fuel inventory (e.g. zirconium-clad, uranium-zirconium alloy fuel). A Mobile Melt-Dilute facility (MMD) is being proposed for treatment of spent fuels at reactor site storage locations in Russia; thereby, avoiding the costs of building separate treatment facilities at each site and avoiding shipment of enriched fuel assemblies over the road. The MMD facility concept is based on laboratory tests conducted at the Savannah River Technology Center (SRTC), and modular pilot-scale facilities constructed at the Savannah River Site for treatment of US spent fuel. SRTC laboratory tests have shown the feasibility of operating a Melt-Dilute treatment process with either a closed system or a filtered off-gas system. The proposed Mobile Melt-Dilute process is presented in this paper

    Full Text Available A probability of the harmonization of the Chinese sub-global strategy ‘One Belt, One Road’, proposed in 2013, and Russian integration project for the Eurasia economic cooperation are reviewed as well as the influence of this potential synchronized project on the Far Eastern segment of the Russian spatial strategy. It is noted that the problems of spatial heterogeneity gave push to the ‘One Belt, One Road’ project when China approached the point in economic development where different regional economic zones demand new infrastructural solutions for maintaining economic dynamics. The article shows that the declared co-development of countries involved is based on the rigid pragmatic financial-credit and infrastructural expansion of Central Asian model: mandatory provision of significant share in property (controlling stake, if possible, mandatory financing with construction contract and guaranteed future export of services for operating the facilities, ensuring the rights on full (or no less than 50% export of raw materials for further processing to China, employing Chinese labor in Russian-Chinese enterprises, and using Chinese machinery and equipment

    Higher-derivative gravity theories, such as Lovelock theories, generalize Einstein's general relativity (GR). Modifications to GR are expected when curvatures are near Planckian and appear in string theory or supergravity. But can such theories describe gravity on length scales much larger than the Planck cutoff length scale? Here we find causality constraints on Lovelock theories that arise from the requirement that the equations of motion (EOM) of perturbations be hyperbolic. We find a general expression for the "effective metric" in field space when Lovelock theories are perturbed around some symmetric background solution. In particular, we calculate explicitly the effective metric for a general Lovelock theory perturbed around cosmological Friedman-Robertson-Walker backgrounds and for some specific cases when perturbed around Schwarzschild-like solutions. For the EOM to be hyperbolic, the effective metric needs to be Lorentzian. We find that, unlike for GR, the effective metric is generically not Lorentzian when the Lovelock modifications are significant. So, we conclude that Lovelock theories can only be considered as perturbative extensions of GR and not as truly modified theories of gravity. We compare our results to those in the literature and find that they agree with and reproduce the results of previous studies.

    In this paper, we apply the multifractal detrended fluctuation analysis (MFDFA) to the Russian stock price returns. To the best of our knowledge, this paper is the first to reveal the multifractal structures for the Russian stock market by financial crises. The contributions of the paper are twofold. (i) Finding the multifractal structures for the Russian stock market. The generalized Hurst exponents estimated become highly-nonlinear to the order of the fluctuation functions. (ii) Computing the multifractality degree according to Zunino et al. (2008). We find that the multifractality degree of the Russian stock market can be categorized within emerging markets, however, the Russian 1998 crisis and the global financial crisis dampen the degree when we consider the order of the polynomial trends in the MFDFA.

    Full Text Available Recently, Russian olive trees showing witches’-broom and little leaf symptoms have been widely observed in northwestern and central Iran. Polymerase chain reaction (PCR and nested PCR assays using phytoplasma universal primer pairs confirmed phytoplasma symptomatic infection of trees. Sequence analyses showed that ‘Candidatus Phytoplasma asteris’ was the causal agent of the disease in these regions. However, RFLP results using restriction enzymes HpaII, EcoRI, HinfI and AluI indicated that the collected isolates in these regions are genetically different. In addition, leafhopper Macropsis infuscata was recognized as a possible insect vector of the disease for the first time.

  4. Causal inference, probability theory, and graphical insights.

    2013-11-10

    Causal inference from observational studies is a fundamental topic in biostatistics. The causal graph literature typically views probability theory as insufficient to express causal concepts in observational studies. In contrast, the view here is that probability theory is a desirable and sufficient basis for many topics in causal inference for the following two reasons. First, probability theory is generally more flexible than causal graphs: Besides explaining such causal graph topics as M-bias (adjusting for a collider) and bias amplification and attenuation (when adjusting for instrumental variable), probability theory is also the foundation of the paired availability design for historical controls, which does not fit into a causal graph framework. Second, probability theory is the basis for insightful graphical displays including the BK-Plot for understanding Simpson's paradox with a binary confounder, the BK2-Plot for understanding bias amplification and attenuation in the presence of an unobserved binary confounder, and the PAD-Plot for understanding the principal stratification component of the paired availability design.

  5. Is Transition in the Russian Economy Complete?

    2015-09-01

    Full Text Available A quarter of a century passed since the beginning of market transformation (transition in Russia; nevertheless, there are serious doubts about whether the transition is complete. The effective transition to a new type of economy should ideally be a period of transformation, modernization and the formation of a national economic model. Only in this case can it be qualified as full, adequate, and constructive. Such combination has not taken place in Russia; it seems as if the market transformations were taking place independently, and this is the root of Russia’s many contemporary problems. The current crisis in the Russian economy primarily reflects the pendency of these tasks that were necessary to be solved from the very beginning of transformation. This crisis is first of all a focused expression and continuation of the transformation and reproduction crises in the national economy, the crisis of the current defective economic models and the then pursued economic policy. External factors only facilitated the exacerbation of Russia’s internal problems. In order to respond effectively to such a large-scale crisis it is necessary to consider all its aspects and underlying causes originating in the challenges of the transition period. Only the implementation of economic modernization and the formation of an effective national economic model is able to bring the Russian economy to a new level of development and thus to bring the transformation, which is lagging behind due to historical reasons, in line with these processes. In this case there will be good reason to conclude that the final border of the transition period is overcome. A new model of Russia’s economy must be adequate to the entire set of national-specific factors and strategic and vital development goals that Russia has. The core of modernization must be new industrialization, which is characterized by the transition to automation, computerization, greening of industrial

    Full Text Available This article focuses on a number of reasons, redemption of private railways in the Russian Empire during the reign of Alexander III. Preconditions for this step. After the defeat in the Crimean War, the state began to consider two basic ways construction of railways: the expense of the treasury at the expense of private capital, including foreign ones. Attempts to organize joint capital of private foreign and domestic on the example of the main Russian Railway Company ended sadly. Foreign capital is mainly interested in speculation on the Russian stock exchange, as a result the majority of the company's shares went to the Russian capital. To support the private Russian capital the government has gone the way of the guarantee capital, in certain cases, as a joint stock or bond or one of the types of capital. When distribution concessions were not crucial economic factors, and the proximity to the elite or the corruption component. Often concession won by those who offered the lowest price, which affects the quality of railway construction in the country. As a result of the concession is not got the most professionally trained people who are almost entirely the burden shifted to the state, and profits for the most part getting any private owners. As a result, such practice is ruinous for the Treasury forced the government to buy back a significant portion of private railways on acceptable terms. As a result, initially malpractice and corruption safeguards prevent a real manifestation of self-employment initiatives

    2017-09-01

    Connectivity analysis is performed on a long financial record of 21 international stock indices employing a linear and a nonlinear causality measure, the conditional Granger causality index (CGCI) and the partial mutual information on mixed embedding (PMIME), respectively. Both measures aim to specify the direction of the interrelationships among the international stock indexes and portray the links of the resulting networks, by the presence of direct couplings between variables exploiting all available information. However, their differences are assessed due to the presence of nonlinearity. The weighted networks formed with respect to the causality measures are transformed to binary ones using a significance test. The financial networks are formed on sliding windows in order to examine the network characteristics and trace changes in the connectivity structure. Subsequently, two statistical network quantities are calculated; the average degree and the average shortest path length. The empirical findings reveal interesting time-varying properties of the constructed network, which are clearly dependent on the nature of the financial cycle.

    Jaundice is a common and complex clinical symptom potentially occurring in hepatology, general surgery, pediatrics, infectious diseases, gynecology, and obstetrics, and it is fairly difficult to distinguish the cause of jaundice in clinical practice, especially for general practitioners in less developed regions. With collaboration between physicians and artificial intelligence engineers, a comprehensive knowledge base relevant to jaundice was created based on demographic information, symptoms, physical signs, laboratory tests, imaging diagnosis, medical histories, and risk factors. Then a diagnostic modeling and reasoning system using the dynamic uncertain causality graph was proposed. A modularized modeling scheme was presented to reduce the complexity of model construction, providing multiple perspectives and arbitrary granularity for disease causality representations. A “chaining” inference algorithm and weighted logic operation mechanism were employed to guarantee the exactness and efficiency of diagnostic reasoning under situations of incomplete and uncertain information. Moreover, the causal interactions among diseases and symptoms intuitively demonstrated the reasoning process in a graphical manner. Verification was performed using 203 randomly pooled clinical cases, and the accuracy was 99.01% and 84.73%, respectively, with or without laboratory tests in the model. The solutions were more explicable and convincing than common methods such as Bayesian Networks, further increasing the objectivity of clinical decision-making. The promising results indicated that our model could be potentially used in intelligent diagnosis and help decrease public health expenditure. PMID:28471111

    Full Text Available During the crisis it is especially important to choose a correct employment strategy. Every employee uses an employment strategy, as he/she selects the direction of long-term employment consciously or intuitively. The choice of strategy is determined by a number of factors shaping the person’s attitudes: health, character, upbringing, education, social environment, institutional environment. The employment strategies of the young people newly entering the labor market differ from lab our strategies of workers. Young people do not have such experience and can plan their life “from scratch”. The Soviet specialists, people who started their career in the planned economy, have their own features of employment strategies. The article describes employment strategies of the Russians

    In this paper, we propose a new approach to characterize time series with noise perturbations in both the time and frequency domains by combining Granger causality and complex networks. We construct directed and weighted complex networks from time series and use representative network measures to describe their physical and topological properties. Through analyzing the typical dynamical behaviors of some physical models and the MIT-BIH human electrocardiogram data sets, we show that the proposed approach is able to capture and characterize various dynamics and has much potential for analyzing real-world time series of rather short length.

    2017-04-01

    The role of randomness, environment and genetics in cancer development is debated. We approach the discussion by using the potential outcomes framework for causal inference. By briefly considering the underlying assumptions, we suggest that the antagonising views arise due to estimation of substantially different causal effects. These effects may be hard to interpret, and the results cannot be immediately compared. Indeed, it is not clear whether it is possible to define a causal effect of chance at all.

    Ernst Mayr's concept of dual causality in biology with the two forms of causes (proximate and ultimate) continues to provide an essential foundation for the philosophy of biology. They are equivalent to functional (=proximate) and evolutionary (=ultimate) causes with both required for full biological explanations. The natural sciences can be classified into nomological, historical nomological and historical dual causality, the last including only biology. Because evolutionary causality is unique to biology and must be included for all complete biological explanations, biology is autonomous from the physical sciences.

    The present work is the first systematic attempt at answering the following fundamental question: what mathematical structures does Einstein-Weyl causality impose on a point-set that has no other previous structure defined on it? The authors propose an axiomatization of Einstein-Weyl causality (inspired by physics), and investigate the topological and uniform structures that it implies. Their final result is that a causal space is densely embedded in one that is locally a differentiable manifold. The mathematical level required of the reader is that of the graduate student in mathematical physics. (orig.)

The Ministry of Health and Social Development and its associated federal services are the principal Russian institutions subserving the Russian Federation. Funding for the health system goes through 2 channels: the general revenue budget managed by federal, regional, and local health authorities, and the Mandatory Health Insurance Fund. Although the Soviet Union was the first country in the world to guarantee free medical care as a constitutional right to all its citizens, quality and accessibility are in question.

This analysis examines Russian price and tax policies as well as production costs in 1993, and their effect on supply and demand in the oil, coal, gas and electricity sectors. The study underscores the broad consensus among both Western and Russian experts that primary energy prices should be lifted to world levels. It offers a framework for addressing the great question about how fast this should be done in a country undergoing a tremendous social and political transformation

    2018-06-01

    The availability of intensive longitudinal data obtained by means of ambulatory assessment opens up new prospects for prevention research in that it allows the derivation of subject-specific dynamic networks of interacting variables by means of vector autoregressive (VAR) modeling. The dynamic networks thus obtained can be subjected to Granger causality testing in order to identify causal relations among the observed time-dependent variables. VARs have two equivalent representations: standard and structural. Results obtained with Granger causality testing depend upon which representation is chosen, yet no criteria exist on which this important choice can be based. A new equivalent representation is introduced called hybrid VARs with which the best representation can be chosen in a data-driven way. Partial directed coherence, a frequency-domain statistic for Granger causality testing, is shown to perform optimally when based on hybrid VARs. An application to real data is provided.

    Full Text Available Population is concentrated in urban areas can cause the external diseconomies on environment if it exceeds the carrying capacity of the space and the urban economy. Otherwise the quality of the environment is getting better, led to the concentration of population in urban areas are increasingly high. This study aims to analyze the relationship of causality between the urban concentration and environmental quality in urban agglomeration areas. The data used in the study of secondary data obtained from the Central Bureau of statistics and the City Government from 2000 to 2013. The analytical method used is the Granger causality and descriptive. Granger causality study results showed no pattern of reciprocal causality, between urban concentration and the quality of the environment, but there unidirectional relationship between the urban concentration and environmental quality. This means that increasing urban concentration led to decreased environmental quality.

  4. Selecting appropriate cases when tracing causal mechanisms

    The last decade has witnessed resurgence in the interest in studying the causal mechanisms linking causes and outcomes in the social sciences. This article explores the overlooked implications for case selection when tracing mechanisms using in-depth case studies. Our argument is that existing case...... selection guidelines are appropriate for research aimed at making cross-case claims about causal relationships, where case selection is primarily used to control for other causes. However, existing guidelines are not in alignment with case-based research that aims to trace mechanisms, where the goal...... is to unpack the causal mechanism between X and Y, enabling causal inferences to be made because empirical evidence is provided for how the mechanism actually operated in a particular case. The in-depth, within-case tracing of how mechanisms operate in particular cases produces what can be termed mechanistic...

  5. Rate-Agnostic (Causal) Structure Learning.

    Causal structure learning from time series data is a major scientific challenge. Extant algorithms assume that measurements occur sufficiently quickly; more precisely, they assume approximately equal system and measurement timescales. In many domains, however, measurements occur at a significantly slower rate than the underlying system changes, but the size of the timescale mismatch is often unknown. This paper develops three causal structure learning algorithms, each of which discovers all dynamic causal graphs that explain the observed measurement data, perhaps given undersampling. That is, these algorithms all learn causal structure in a "rate-agnostic" manner: they do not assume any particular relation between the measurement and system timescales. We apply these algorithms to data from simulations to gain insight into the challenge of undersampling.

  6. K-causality and degenerate spacetimes

    The causal relation K+ was introduced by Sorkin and Woolgar to extend the standard causal analysis of C2 spacetimes to those that are only C0. Most of their results also hold true in the case of metrics with degeneracies which are C0 but vanish at isolated points. In this paper we seek to examine K+ explicitly in the case of topology-changing `Morse histories' which contain degeneracies. We first demonstrate some interesting features of this relation in globally Lorentzian spacetimes. In particular, we show that K+ is robust and the Hawking and Sachs characterization of causal continuity translates into a natural condition in terms of K+. We then examine K+ in topology-changing Morse spacetimes with the degenerate points excised and then for the Morse histories in which the degenerate points are reinstated. We find further characterizations of causal continuity in these cases.

    An essential goal of program evaluation and scientific research is the investigation of causal mechanisms. Over the past several decades, causal mediation analysis has been used in medical and social sciences to decompose the treatment effect into the natural direct and indirect effects. However, all of the existing mediation analysis methods rely on parametric modeling assumptions in one way or another, typically requiring researchers to specify multiple regression models involving the treat...

    We investigate the extrinsic geometry of causal sets in $(1+1)$-dimensional Minkowski spacetime. The properties of boundaries in an embedding space can be used not only to measure observables, but also to supplement the discrete action in the partition function via discretized Gibbons-Hawking-York boundary terms. We define several ways to represent a causal set using overlapping subsets, which then allows us to distinguish between null and non-null bounding hypersurfaces in an embedding space...

    2008-02-15

    In 2004, President Poutine decided to replace the atomic energy ministry (Minatom) by the federal atomic energy agency (Rosatom). Several projects were launched during the next two years which aimed at bringing back Russia to the fore front of the world leaders of nuclear energy use and nuclear technology export. In 2007, Rosatom agency was changed to a public holding company and a new company, named Atomenergoprom, was created which gathers all civil nuclear companies (AtomEnergoMash for the exploitation of power plants, Technabsexport (Tenex) specialized in enrichment or Atomstryexport in charge of export activities). Thus, Rosatom is at the head of all civilian and military nuclear companies, of all research centers, and of all nuclear and radiological safety facilities. In 2006, Russian nuclear power plants supplied 15.8% of the whole power consumption. Russia wishes to develop its nuclear program with the construction of new reactors in order to reach a nuclear electricity share of 25% from now to 2020. This paper presents first the 2007 institutional reform of the Russian atomic sector, and the three sectorial federal programmes: 1 - development of the nuclear energy industrial complex for the 2007-2010 era and up to 2015 (future power plants, nuclear fuel centers and reactor prototypes), 2 - nuclear safety and radioprotection for the 2008-2015 era (waste management, remedial actions, radiation protection), 3 - military program (confidential). Then, the paper presents: the international actions (export of Russian technology, cooperation agreements, non-proliferation), the situation of the existing nuclear park (reactors in operation, stopped, under construction and in project), the fuel cycle activities (production of natural uranium, enrichment, fuel fabrication, spent fuel storage, reprocessing, waste management), the nuclear R and D in Russia, and the nuclear safety authority.

    1997-01-01

    The April 1996, G7 Moscow Summit on nuclear matters provided a political framework for one of the most current significant challenges: ensuring a consistent answer to the weapons grade fissile material disposition issue resulting from the disarmament effort engaged by both the USA and Russia. International technical assessments have showed that the transformation of Weapons grade Plutonium in MOX fuel is a very efficient, safe, non proliferant and economically effective solution. In this regard, COGEMA and SIEMENS, have set up a consistent technical program properly addressing incineration of weapons grade plutonium in MOX fuels. The leading point of this program would be the construction of a Weapons grade Plutonium dedicated MOX fabrication plant in Russia. Such a plant would be based on the COGEMA-SIEMENS industrial capabilities and experience. This facility would be operated by MINATOM which is the partner for COGEMA-SIEMENS. MINATOM is in charge of coordination of the activity of the Russian research and construction institutes. The project take in account international standards for non-proliferation, safety and waste management. France and Germany officials reasserted this position during their last bilateral summits held in Fribourg in February and in Dijon in June 1996. MINATOM and the whole Russian nuclear community have already expressed their interest to cooperate with COGEMA-SIEMENS in the MOX field. This follows governmental-level agreements signed in 1992 by French, German and Russian officials. For years, Russia has been dealing with research and development on MOX fabrication and utilization. So, the COGEMA-SIEMENS MOX proposal gives a realistic answer to the management of weapons grade plutonium with regard to the technical, industrial, cost and schedule factors. (author)

    One of the main problems of nutrition of children and adolescents is to assess chemical contamination of baby food products and the establishment of the relation with the health of the child population. With the entering different chemical compounds in the body of the child there can be observed disorders of the nervous, urinary, cardiovascular system, gastrointestinal tract, as well as metabolic deteriorations, degenerative processes in parenchymal organs and bone destruction. The aim of the study was to analyze data on chemical contamination of baby food products in the Russian Federation for 2012-2014. The analysis was executed on the data of Federal Information Fund of social and hygienic monitoring of the Russian Federation. There were identified priority pollutants (toxic elements, nitrites, nitrates, nitrosamines, pesticides, hydroxymethylfurfural, mycotoxins) and risk areas (the Lipetsk region, the Krasnodar Territory, the Republic of Adygea, city of Moscow, Tatarstan, the Kabardino-Balkar Republic, the Ryazan region). There are detected contamination levels not exceeding MAC (in the dynamics of the three years offollow up, on average 22%), requiring their hygienic assessment. There were determined the baby food products containing most common occurred chemical contaminants: fruits and vegetables products, canned products, canned meat, cereals, dairy products, liquid and adapted and partially adapted milk formalas. Identified data indicate to a need for further studies of chemical substances in products for children’s nutrition in order to establish the causal relationships with a various diseases and the substantiation of methodological approaches to the risk assessment of combined exposure to chemical contaminants in concentrations up to the MPC on health of children, including infants.

    Full Text Available This article analyzes a diverse range of the enterprise’s export potential growth factors in emerging pharmaceutical clusters of Central European Russia. Classification and comparative analysis were used to identify export potential attributes (production, finance, labor and marketing, which have allowed to reveal the strong connection of cluster and regional factor groups with the results of export performance. The purpose of the study is to provide exports-seeking pharmaceutical companies with a set of tools to enhance their export potential. The hypothesis that the cumulative impact of the specified attributes leads to the strengthening of pharmaceutical cluster export potential and promotes an effective integration of the region in the world economic space, is developed and tested. The methodology combines the geo-economy-based theory with the theory of clusters competitive advantages. The impacts of export potential growth factors are estimated by using an econometric model based on math statistics. Thus, five Russian regional pharmaceutical clusters (Belgorod, Kaluga, Moscow, Oryol, Yaroslavl are shown. Findings identify an objective causal link between enterprise export potential growth and competitiveness factors of cluster origin (network business chains, production functions interconnectedness and flexibility, production localization. An action plan for the purpose of the maximum use of competitive advantages of the cluster organization for export activities of the entities of the pharmaceutical industry is developed. Conclusions and recommendations of the study are intended to enterprises in pharmaceutical industry and regions’ public authorities, implementing cluster development strategies. It is thus essential to improve marketing and organizational innovations, reduction of commercial expenses under the cluster environment, development of drugs production and delivery chains from R&D to end-users in order to enjoy greater

  14. Causal strength induction from time series data.

    Soo, Kevin W; Rottman, Benjamin M

    2018-04-01

    One challenge when inferring the strength of cause-effect relations from time series data is that the cause and/or effect can exhibit temporal trends. If temporal trends are not accounted for, a learner could infer that a causal relation exists when it does not, or even infer that there is a positive causal relation when the relation is negative, or vice versa. We propose that learners use a simple heuristic to control for temporal trends-that they focus not on the states of the cause and effect at a given instant, but on how the cause and effect change from one observation to the next, which we call transitions. Six experiments were conducted to understand how people infer causal strength from time series data. We found that participants indeed use transitions in addition to states, which helps them to reach more accurate causal judgments (Experiments 1A and 1B). Participants use transitions more when the stimuli are presented in a naturalistic visual format than a numerical format (Experiment 2), and the effect of transitions is not driven by primacy or recency effects (Experiment 3). Finally, we found that participants primarily use the direction in which variables change rather than the magnitude of the change for estimating causal strength (Experiments 4 and 5). Collectively, these studies provide evidence that people often use a simple yet effective heuristic for inferring causal strength from time series data.

  15. Kant on causal laws and powers.

    Science.gov (United States)

    Henschen, Tobias

    2014-12-01

    The aim of the paper is threefold. Its first aim is to defend Eric Watkins's claim that for Kant, a cause is not an event but a causal power: a power that is borne by a substance, and that, when active, brings about its effect, i.e. a change of the states of another substance, by generating a continuous flow of intermediate states of that substance. The second aim of the paper is to argue against Watkins that the Kantian concept of causal power is not the pre-critical concept of real ground but the category of causality, and that Kant holds with Hume that causal laws cannot be inferred non-inductively (that he accordingly has no intention to show in the Second analogy or elsewhere that events fall under causal laws). The third aim of the paper is to compare the Kantian position on causality with central tenets of contemporary powers ontology: it argues that unlike the variants endorsed by contemporary powers theorists, the Kantian variants of these tenets are resistant to objections that neo-Humeans raise to these tenets.

    Automated and semiautomated Twitter accounts, bots, have recently gained significant public attention due to their potential interference in the political realm. In this study, we develop a methodology for detecting bots on Twitter using an ensemble of classifiers and apply it to study bot activity within political discussions in the Russian Twittersphere. We focus on the interval from February 2014 to December 2015, an especially consequential period in Russian politics. Among accounts actively Tweeting about Russian politics, we find that on the majority of days, the proportion of Tweets produced by bots exceeds 50%. We reveal bot characteristics that distinguish them from humans in this corpus, and find that the software platform used for Tweeting is among the best predictors of bots. Finally, we find suggestive evidence that one prominent activity that bots were involved in on Russian political Twitter is the spread of news stories and promotion of media who produce them.

The main bioethical principles were established during the formation of the Russian clinical school and neurosciences. It is most distinctly seen in the development of bioethics in neurology and epileptology. In the author's opinion, the Russian scientist V.M. Bekhterev had played a prominent role in the field. In the time when the term "bioethics" was not coined and its principles were not formulated, V.M. Bekhterev had created the Russian league against epilepsy and established the foundations of the International League Against Epilepsy (ILAE) as the organizations working on the problems of medical and social care to patients with epilepsy. In Russia, the Russian society of neurologists has been doing a great work in the field.

    Full Text Available Central Asian nations faced a challenge of state-building objectives after the collapse of the USSR. However, it was a complicated task, because those nations were parts of the Russian and, lately, the Soviet state. State-building objectives include the creation of new historical narrative. Central Asia is now experiencing the process that is called "national novel" in the Western European historiography. Central Asian national variants of historical narratives serve as a conceptual basis for the writing of school and university textbooks. The introduction of ideological constructs through the education system is carried out everywhere. However, it is important to note that inevitable ideological indoctrination should not undermine scientific essence of textbooks. Politics of nation formation and the preservation of its identity is implemented and fostered by states carefully as well as clumsy. There is no doubt that there is an inevitable and practical need for constructing "national novel" in the new states. But historical politics should not ignore some of the methodological and at the same time mental traps that exist in the field of studying the history of the peoples of Central Asia in the period of the Russian Empire.

    2014-12-01

    Full Text Available The article deals with the experience of the Russian empire of the 19 th century in creating the conditions for social activities of the Russian Orthodox Church. The author describes such types of the Russian Orthodox Church activities aimed at helping those in need as helping the poor, coordinating the work of poor-houses, collecting donations, supporting parochial schools, poor houses, orphanages, hospitals, construction and reconstruction of churches. The author analyzes the role of the parochial patronages in the charity and social service activities, as well as in the moral and spiritual education of the population. The work of the well-known members of the clergy which forms a part of the Russian Orthodox Church and Russian history in general is given as an example of the above mentioned activities. The article extensively covers the responsibilities of parish priests, the difficulties which they come across, and highlights the reasons for the negative attitude towards the clergy in the late 19 th - early 20 th centuries. The author summarizes the historical lessons of the social activity of the Russian Orthodox Church. The article provides grounds for the opinion that the social activities of the Church should not interfere with its main religious functions, and the partnership of the state and the Russian Orthodox Church in the social projects should contribute to the improvement of people’s life and their moral and spiritual growth.

    Full Text Available Abstract Background People hold a wide variety of beliefs concerning the causes of illness. Such beliefs vary across cultures and, among immigrants, may be influenced by many factors, including level of acculturation, gender, level of education, and experience of illness and treatment. This study examines illness causal beliefs in Turkish-immigrants in Australia. Methods Causal beliefs about somatic and mental illness were examined in a sample of 444 members of the Turkish population of Melbourne. The socio-demographic characteristics of the sample were broadly similar to those of the Melbourne Turkish community. Five issues were examined: the structure of causal beliefs; the relative frequency of natural, supernatural and metaphysical beliefs; ascription of somatic, mental, or both somatic and mental conditions to the various causes; the correlations of belief types with socio-demographic, modernizing and acculturation variables; and the relationship between causal beliefs and current illness. Results Principal components analysis revealed two broad factors, accounting for 58 percent of the variation in scores on illness belief scales, distinctly interpretable as natural and supernatural beliefs. Second, beliefs in natural causes were more frequent than beliefs in supernatural causes. Third, some causal beliefs were commonly linked to both somatic and mental conditions while others were regarded as more specific to either somatic or mental disorders. Last, there was a range of correlations between endorsement of belief types and factors defining heterogeneity within the community, including with demographic factors, indicators of modernizing and acculturative processes, and the current presence of illness. Conclusion Results supported the classification of causal beliefs proposed by Murdock, Wilson & Frederick, with a division into natural and supernatural causes.

    A genetic stock certification assay was developed to distinguish Russian honey bees from other European (Apis mellifera L.) stocks that are commercially produced in the United States. In total, 11 microsatellite and five single-nucleotide polymorphism loci were used. Loci were selected for relatively high levels of homogeneity within each group and for differences in allele frequencies between groups. A baseline sample consisted of the 18 lines of Russian honey bees released to the Russian Bee Breeders Association and bees from 34 queen breeders representing commercially produced European honey bee stocks. Suitability tests of the baseline sample pool showed high levels of accuracy. The probability of correct assignment was 94.2% for non-Russian bees and 93.3% for Russian bees. A neighbor-joining phenogram representing genetic distance data showed clear distinction of Russian and non-Russian honey bee stocks. Furthermore, a test of appropriate sample size showed a sample of eight bees per colony maximizes accuracy and consistency of the results. An additional 34 samples were tested as blind samples (origin unknown to those collecting data) to determine accuracy of individual assignment tests. Only one of these samples was incorrectly assigned. The 18 current breeding lines were represented among the 2009 blind sampling, demonstrating temporal stability of the genetic stock identification assay. The certification assay will be used through services provided by a service laboratory, by the Russian Bee Breeders Association to genetically certify their stock. The genetic certification will be used in conjunction with continued selection for favorable traits, such as honey production and varroa and tracheal mite resistance.

    Full Text Available Branding literature suggests that consumer-based brand equity (CBBE is a multidimensional construct. Starting from this approach and developing a conceptual multidimensional model, this study finds that CBBE can be best modelled with a two-dimensional structure and claims that it achieves this result by choosing the theoretically based causal specification. On the contrary, with reflective specification, one will be able to fit almost any valid construct because of the halo effect and common method bias. In the final model, Trust (in quality and Advantage are causing the second-order Brand Equity. The two-dimensional brand equity is an intuitive model easy to interpret and easy to measure, which thus may be a much more attractive means for the management as well.

  15. Term Croatian considered in russian context

    Full Text Available Term Croatian is considered in Russian context, i. e. context of Russian scientific material (which is comparable to the unwritten situation in universities. Russian scientific texts connect term Croatian, almost without an exception, with the term Serbian in words such as Serbo-Croatian. This point of view is politically approved in the period untill 1990’s, but it exists in the 21st century’s scientific material. The nature of the problem lays, at the same time, in politics, language and society; thus, the question is: what is the reason of such a context in which Croatian language is placed now? There are no arguments for it, especially if it is for Slovak language politically based and language approved to be an entity – in comparison to the Czech language; for Ukrainian (once Littlerussian – at least in principle, in comparison to the Russian, or, more convincable, Belorussian to Russian (the standard Belorussian language exists from 1905. The term Croatian is independently, even in new books, connected with terms of soil, state, nation, but not language. And though today, because of political reasons, exists an awareness of Croatian language without its Serbian mirror reflexion, the term Serbo-Croatian stays. Thus, this paper looks through the history concerning Croatian language in 19, 20 and 21st century’s Russian philology, including Juraj Križanić and Vatroslav Jagić – innovators of the Croatian word in Russia.

  16. Russian Language in the Central Asia Region

    Full Text Available He article is devoted to the role of the Russian language in Central Asia and its development perspectives in the context of the Eurasian integration processes. Russian language has a long historical tradition in Central Asia and hasn't lost its importance even at the background of two waves of "derussification" that took place after 1991. Notwithstanding the decrease of the status, it keeps substantial public significance. During last two decades only in Turkmenistan we are witnessing the decrease in spreading of the Russian language among title population of the Central Asia region. Its positions as an active communication channel is secured not only by the social tradition, but also by the competitiveness of the Russian language education, advantages of the bilingual business, requirements of the labor migrants, HR interests and by some other pragmatic thoughts, which role within the context of Eurasian economic integration will increase. Despite the difficulties, it is too early to speak about the decrease of the Russian language in the Central Asia region. It is more likely that the institutes itself that maintain it and promoting it are at the low ebb. New scales and forms of practical work that is interested not only for Russia, but also Central Asia countries are required. Pressure on the resources of the Russian language increases the possibility of ethnic conflicts and strengthens the positions of political radicalism in Central Asia region.

  18. The causal approach in quantum field theory

    Grigore, D. R.

    2003-01-01

    The mathematical formulation of perturbative renormalization theory starts from Bogoliubov axioms imposed on the S-matrix (or equivalently on the chronological products). The S-matrix is a formal series of operator valued distributions: these distributions are denoted by T(x 1 , ... , x n ) and one supposes that they act in the Fock space of some collection of free fields. These operator-valued distributions are called chronological products. The expression T(x) is called the interaction Lagrangian. It is convenient to construct more general objects namely, the operator-valued distributions T(W 1 (x 1 ), ... ,W n (x n )), where W j are arbitrary Wick monomials. These objects verify some properties (following from Bogolyubov axioms) and express the following properties: the initial condition, skew-symmetry in all arguments, Poincare invariance, causality and unitarity. The existence of solutions follows from the analysis of Epstein and Glaser as a recursive procedure using in an essential way the causality axiom. Sometimes it is possible to supplement these axioms by other invariance properties with respect to space-time symmetries (inversions and/or scale invariance), charge conjugation, global symmetry with respect to some internal symmetry group, supersymmetric invariance, etc. if they are valid for the interaction Lagrangian. In the literature, the invariance properties of the chronological products with respect to scale invariance was analyzed in detail. The scale invariance operators U λ are transforming field operators corresponding to particles of masses m j in fields corresponding to scaled masses λ -1 m j . One can prove that if all masses are positive the chronological products can be normalized such that they are scale invariant. On the contrary, if all masses of the model are zero then the scale invariance of the chronological products can be implemented only up to some logarithmic terms in λ. For models describing higher spin particles unphysical

    2003-01-01

    My particular view about Russian nuclear energetics perspectives is presented. The nearest and the further perspectives are considered. The arguments are adduced that the most probable scenario of nuclear energetic development is its stabilization in the near future. Fur further development the arguments of supporters and opponents of nuclear energetics are analyzed. Three points of view are considered. The first point of view that there is not alternative for nuclear energetics. My notes are the following ones. a) I express a skeptic opinion about a statement of quick exhaustion of fossil organic fuel recourses and corresponding estimations are presented. b) It is expressed skeptic opinion about the statement that nuclear energetics can have a visual influence on ''steam effect''. c) I agree that nuclear energetics is the most ecological technology for normal work but however we can't disregard possibilities of catastrophic accidents. The second point of view that the use of nuclear energetics can't have the justification. I adduce the arguments contrary to this statement. The third point of view that nuclear energetics is a usual technology and the only criteria for discussions about what dimension and where one ought develop it is total cost of its unit. Expressed an opinion that the deceived for the choose of a way the skill of the estimate correctly and optimized so named the external parts of the unit energy costs for different energy technologies.

    After three years of evaluating prospects and negotiating with government and industry representatives, Gulf Canada established its first joint venture in the Russian Federation with Komineft, a production association from the Komi autonomous republic. Komineft has a 50% share of the venture, and the rest is shared equally between Gulf and British Gas. The operating area is at the Vozey and Upper Vozey fields in the Timan-Pechora Basin, some 1,500 km northeast of Moscow just inside the Arctic Circle. An attractive feature of the Upper Vozey project is low development costs of ca $2/bbl. In the Vozey field, the venture will set up an enhanced oil recovery demonstration project to test techniques perfected in Alberta. About 60 Canadians are involved on the project, and headquarters are in Usinsk, ca 100 km south of the oil fields. In the first half of 1992, oil production in the first phase of the venture averaged around 10,000 bbl/d and continues to increase

    Here, we report first results of the large-scale ongoing bioelectrical impedance body composition study in Russians. By the end of 2012, 216 out of 800 Russian Health Centres submitted raw bioimpedance data on 844,221 adults and children aged 5-80 years, representing nearly 0.6% of the Russian population, who were accessed cross-sectionally using the same type of bioimpedance meter, ABC-01 Medas. Estimates of overweight, obesity, and normal weight obesity prevalence in the general population, as well as characteristics of diagnostic sensitivity and specificity of the conventional WHO BMI-based criteria of obesity depending on age are obtained. The smoothed reference centile curves for percentage fat mass are constructed, and localized cut-offs for fatness and thinness are provided that can be used both at the individual and epidemiological levels.

  7. Entanglement entropy in causal set theory

    Science.gov (United States)

    Sorkin, Rafael D.; Yazdi, Yasaman K.

    2018-04-01

    Entanglement entropy is now widely accepted as having deep connections with quantum gravity. It is therefore desirable to understand it in the context of causal sets, especially since they provide in a natural manner the UV cutoff needed to render entanglement entropy finite. Formulating a notion of entanglement entropy in a causal set is not straightforward because the type of canonical hypersurface-data on which its definition typically relies is not available. Instead, we appeal to the more global expression given in Sorkin (2012 (arXiv:1205.2953)) which, for a Gaussian scalar field, expresses the entropy of a spacetime region in terms of the field’s correlation function within that region (its ‘Wightman function’ W(x, x') ). Carrying this formula over to the causal set, one obtains an entropy which is both finite and of a Lorentz invariant nature. We evaluate this global entropy-expression numerically for certain regions (primarily order-intervals or ‘causal diamonds’) within causal sets of 1  +  1 dimensions. For the causal-set counterpart of the entanglement entropy, we obtain, in the first instance, a result that follows a (spacetime) volume law instead of the expected (spatial) area law. We find, however, that one obtains an area law if one truncates the commutator function (‘Pauli–Jordan operator’) and the Wightman function by projecting out the eigenmodes of the Pauli–Jordan operator whose eigenvalues are too close to zero according to a geometrical criterion which we describe more fully below. In connection with these results and the questions they raise, we also study the ‘entropy of coarse-graining’ generated by thinning out the causal set, and we compare it with what one obtains by similarly thinning out a chain of harmonic oscillators, finding the same, ‘universal’ behaviour in both cases.

  8. Causal relations among events and states in dynamic geographical phenomena

    2007-06-01

    There is only a static state of the real world to be recorded in conventional geographical information systems. However, there is not only static information but also dynamic information in geographical phenomena. So that how to record the dynamic information and reveal the relations among dynamic information is an important issue in a spatio-temporal information system. From an ontological perspective, we can initially divide the spatio-temporal entities in the world into continuants and occurrents. Continuant entities endure through some extended (although possibly very short) interval of time (e.g., houses, roads, cities, and real-estate). Occurrent entities happen and are then gone (e.g., a house repair job, road construction project, urban expansion, real-estate transition). From an information system perspective, continuants and occurrents that have a unique identity in the system are referred to as objects and events, respectively. And the change is represented implicitly by static snapshots in current spatial temporal information systems. In the previous models, the objects can be considered as the fundamental components of the system, and the change is modeled by considering time-varying attributes of these objects. In the spatio-temporal database, the temporal information that is either interval or instant is involved and the underlying data structures and indexes for temporal are considerable investigated. However, there is the absence of explicit ways of considering events, which affect the attributes of objects or the state. So the research issue of this paper focuses on how to model events in conceptual models of dynamic geographical phenomena and how to represent the causal relations among events and the objects or states. Firstly, the paper reviews the conceptual modeling in a temporal GIS by researchers. Secondly, this paper discusses the spatio-temporal entities: objects and events. Thirdly, this paper investigates the causal relations amongst

  10. Preschoolers prefer to learn causal information

    2015-02-01

    Full Text Available Young children, in general, appear to have a strong drive to explore the environment in ways that reveal its underlying causal structure. But are they really attuned specifically to casual information in this quest for understanding, or do they show equal interest in other types of non-obvious information about the world? To answer this question, we introduced 20 three-year-old children to two puppets who were anxious to tell the child about a set of novel artifacts and animals. One puppet consistently described causal properties of the items while the other puppet consistently described carefully matched non-causal properties of the same items. After a familiarization period in which children learned which type of information to expect from each informant, children were given the opportunity to choose which they wanted to hear describe each of eight pictured test items. On average, children chose to hear from the informant that provided causal descriptions on 72% of the trials. This preference for causal information has important implications for explaining the role of conceptual information in supporting early learning and may suggest means for maximizing interest and motivation in young children.

  11. Gravity and matter in causal set theory

    International Nuclear Information System (INIS)

    Sverdlov, Roman; Bombelli, Luca

    2009-01-01

    The goal of this paper is to propose an approach to the formulation of dynamics for causal sets and coupled matter fields. We start from the continuum version of the action for a Klein-Gordon field coupled to gravity, and rewrite it first using quantities that have a direct correspondent in the case of a causal set, namely volumes, causal relations and timelike lengths, as variables to describe the geometry. In this step, the local Lagrangian density L(f;x) for a set of fields f is recast into a quasilocal expression L 0 (f;p,q) that depends on pairs of causally related points pprq and is a function of the values of f in the Alexandrov set defined by those points, and whose limit as p and q approach a common point x is L(f;x). We then describe how to discretize L 0 (f;p,q) and use it to define a causal-set-based action.

    Full Text Available The article examines concept of family in Russian society, changes in interpretation of family, connected with modern tendencies and processes in different sociocultural spheres.   The article is structured and has accurate limits of introduction, main part and conclusion. The relevance of the research is caused by present-day crisis tendencies connected with suicide actions, atomization and hedonization of society, value depreciation of family.  The object of the research is to analyze the conception of family and its transformation in condition of modern Russian society. The tasks are to determine the term family, to analyze approaches to understanding of the family and its genesis, detect some peculiarities of modern Russian society, research the transformation of interpretation of family in modern society; the matter of investigation is modern Russian society, the subject is the transformation of family structures; the following methods of research are used: historical and cultural approach, typological method, existential method, common logic procedures. The research contains author’s definition of the term family, historical and cultural analysis and typological explication of the approaches to interpretation of the problem, classification of family structures - which have been formed in Russian society- on the base of statistic and sociological data.   Some interweaving of concept family with the most important existential values (love, freedom, responsibility were investigated and some tendencies for further development of family relationship in Russian society were revealed, its problems and prospect were emphasized. The results of the investigation testify that modern types of matrimonial relationship differ in limitation of functionality, mutual responsibility, thereby it is possible to state that interpretation of family in modern Russian society has transformed.

    Full Text Available Communist rule did not end suddenly in 1989, or in 1991. And for many, at least in Russia, there was no radical break but a complex evolution in which many of the former ruling group, and many of the values of the Soviet period, remained intact. According to the evidence of national representative surveys, levels of support for the principle of a union state have consistently been very high. In 2008 survey, more than half (57% largely or entirely agreed that the demise of the USSR had been a ‘disaster’, and nearly two-thirds (64% thought the former Soviet republics that had established a Commonwealth of Independent States should reconstitute a single state or at least cooperate more closely. Across the three Slavic republics, Russia, Ukraine and Belarus, it was guaranteed employment that was seen as the most positive feature of the old regime, and economic stagnation as its most serious shortcoming. Comparing the present and the Soviet period as they recalled it, ordinary Russians thought they had more opportunity to practise a religion, and to express their opinions. But ordinary people had (in their own view no more influence over the making of public policy than in the communist period, and they thought they were less likely to be treated fairly and equally by government. Age and living standards were the most powerful predictors of Soviet nostalgia when other variables were held constant. Nostalgics were much more likely to support parties of the left, or at least those that favoured public ownership, a Soviet or ‘more democratic Soviet’ system of government, and a closer association among the former Soviet republics; they were much less likely to support the parties that favoured the dissolution of the CIS, a wholly market economy, or Western-style democracy.

  19. Economics of Russian oil production

    International Nuclear Information System (INIS)

    Gubenko, I.

    1993-01-01

    The main technical indicators of oil production in Russia are presented from the year 1988, when the current decline in oil production started. In 1992, only 9 new oil deposits were put into production, and average well productivity dropped to 12.4 tonnes/d. The number of idle wells reached 31,934 as compared to 8,714 in 1988. The share of low productivity deposits in 1993 was 49.7%. In the first five months of 1993, the number of new wells put into operation failed to offset the shutdown of old wells. Although the number of workovers grew by 32%, this work was insufficient to stabilize oil production. The decline in production is due to the general state of economic stability and endless reorganizations in the economy, and to the lack of sufficient investment in the industry. Oil-producing enterprises have lacked funds due to systematic and growing indebtedness of buyers of crude. This overdue indebtedness reached 393 billion rubles by the beginning of 1993. Although domestic oil prices increased sharply in 1991-92, the volume of production in real terms has dropped by nearly a third. Oil is sold at different prices to different categories of buyers. Prices include expenses, profit from which a 32% profits tax is paid, excise taxes, and payments to a centralized price-regulation fund. From the industry point of view, certain reforms are necessary to reconstruct and develop the industry. These include ensuring payments to oil producers, gradual transfer of Russian prices to world levels, lowering taxes, and adoption and refinement of a law on oil. 1 fig., 7 tabs

  20. Causal inheritance in plane wave quotients

    2003-01-01

    We investigate the appearance of closed timelike curves in quotients of plane waves along spacelike isometries. First we formulate a necessary and sufficient condition for a quotient of a general spacetime to preserve stable causality. We explicitly show that the plane waves are stably causal; in passing, we observe that some pp-waves are not even distinguishing. We then consider the classification of all quotients of the maximally supersymmetric ten-dimensional plane wave under a spacelike isometry, and show that the quotient will lead to closed timelike curves iff the isometry involves a translation along the u direction. The appearance of these closed timelike curves is thus connected to the special properties of the light cones in plane wave spacetimes. We show that all other quotients preserve stable causality

  1. Inference of boundaries in causal sets

    Cunningham, William J.

    2018-05-01

    We investigate the extrinsic geometry of causal sets in (1+1) -dimensional Minkowski spacetime. The properties of boundaries in an embedding space can be used not only to measure observables, but also to supplement the discrete action in the partition function via discretized Gibbons–Hawking–York boundary terms. We define several ways to represent a causal set using overlapping subsets, which then allows us to distinguish between null and non-null bounding hypersurfaces in an embedding space. We discuss algorithms to differentiate between different types of regions, consider when these distinctions are possible, and then apply the algorithms to several spacetime regions. Numerical results indicate the volumes of timelike boundaries can be measured to within 0.5% accuracy for flat boundaries and within 10% accuracy for highly curved boundaries for medium-sized causal sets with N  =  214 spacetime elements.

  2. Normalizing the causality between time series

    Liang, X. San

    2015-08-01

    Recently, a rigorous yet concise formula was derived to evaluate information flow, and hence the causality in a quantitative sense, between time series. To assess the importance of a resulting causality, it needs to be normalized. The normalization is achieved through distinguishing a Lyapunov exponent-like, one-dimensional phase-space stretching rate and a noise-to-signal ratio from the rate of information flow in the balance of the marginal entropy evolution of the flow recipient. It is verified with autoregressive models and applied to a real financial analysis problem. An unusually strong one-way causality is identified from IBM (International Business Machines Corporation) to GE (General Electric Company) in their early era, revealing to us an old story, which has almost faded into oblivion, about "Seven Dwarfs" competing with a giant for the mainframe computer market.

    2017-04-01

    Theories of reference are a crucial research topic in analytic philosophy. Since the publication of Kripke's Naming and Necessity, most philosophers have endorsed the causal/historical theory of reference. The goal of this paper is twofold: (i) to discuss a method for testing experimentally the causal theory of reference for proper names by investigating linguistic usage and (ii) to present the results from two experiments conducted with that method. Data collected in our experiments confirm the causal theory of reference for people proper names and for geographical proper names. A secondary but interesting result is that the semantic domain affects reference assignment: while with people proper names speakers tend to assign the semantic reference, with geographical proper names they are prompted to assign the speaker's reference.

  4. Bulk viscous cosmology with causal transport theory

    International Nuclear Information System (INIS)

    Piattella, Oliver F.; Fabris, Júlio C.; Zimdahl, Winfried

    2011-01-01

    We consider cosmological scenarios originating from a single imperfect fluid with bulk viscosity and apply Eckart's and both the full and the truncated Müller-Israel-Stewart's theories as descriptions of the non-equilibrium processes. Our principal objective is to investigate if the dynamical properties of Dark Matter and Dark Energy can be described by a single viscous fluid and how such description changes when a causal theory (Müller-Israel-Stewart's, both in its full and truncated forms) is taken into account instead of Eckart's non-causal one. To this purpose, we find numerical solutions for the gravitational potential and compare its behaviour with the corresponding ΛCDM case. Eckart's and the full causal theory seem to be disfavoured, whereas the truncated theory leads to results similar to those of the ΛCDM model for a bulk viscous speed in the interval 10 −11 || cb 2 ∼ −8

    We investigate the appearance of closed timelike curves in quotients of plane waves along spacelike isometries. First we formulate a necessary and sufficient condition for a quotient of a general space-time to preserve stable causality. We explicitly show that the plane waves are stably causal; in passing, we observe that some pp waves are not even distinguishing. We then consider the classification of all quotients of the maximally supersymmetric ten-dimensional plane wave under a spacelike isometry, and show that the quotient will lead to closed timelike curves iff the isometry involves a translation along the u direction. The appearance of these closed timelike curves is thus connected to the special properties of the light cones in plane wave space-times. We show that all other quotients preserve stable causality.

    Causality provides a natural structure for organizing our experience and language. Causal reasoning during speech production is a distinct aspect of verbal communication, whose related brain processes are yet unknown. The aim of the current study was to investigate the neural mechanisms underlying the continuous generation of cause-and-effect coherences during overt word production. During fMRI data acquisition participants performed three verbal fluency tasks on identical cue words: A novel causal verbal fluency task (CVF), requiring the production of multiple reasons to a given cue word (e.g. reasons for heat are fire, sun etc.), a semantic (free association, FA, e.g. associations with heat are sweat, shower etc.) and a phonological control task (phonological verbal fluency, PVF, e.g. rhymes with heat are meat, wheat etc.). We found that, in contrast to PVF, both CVF and FA activated a left lateralized network encompassing inferior frontal, inferior parietal and angular regions, with further bilateral activation in middle and inferior as well as superior temporal gyri and the cerebellum. For CVF contrasted against FA, we found greater bold responses only in the left middle frontal cortex. Large overlaps in the neural activations during free association and causal verbal fluency indicate that the access to causal relationships between verbal concepts is at least partly based on the semantic neural network. The selective activation in the left middle frontal cortex for causal verbal fluency suggests that distinct neural processes related to cause-and-effect-relations are associated with the recruitment of middle frontal brain areas.

  7. BOLD Granger causality reflects vascular anatomy.

    Directory of Open Access Journals (Sweden)

    J Taylor Webb

    Full Text Available A number of studies have tried to exploit subtle phase differences in BOLD time series to resolve the order of sequential activation of brain regions, or more generally the ability of signal in one region to predict subsequent signal in another region. More recently, such lag-based measures have been applied to investigate directed functional connectivity, although this application has been controversial. We attempted to use large publicly available datasets (FCON 1000, ADHD 200, Human Connectome Project to determine whether consistent spatial patterns of Granger Causality are observed in typical fMRI data. For BOLD datasets from 1,240 typically developing subjects ages 7-40, we measured Granger causality between time series for every pair of 7,266 spherical ROIs covering the gray matter and 264 seed ROIs at hubs of the brain's functional network architecture. Granger causality estimates were strongly reproducible for connections in a test and replication sample (n=620 subjects for each group, as well as in data from a single subject scanned repeatedly, both during resting and passive video viewing. The same effect was even stronger in high temporal resolution fMRI data from the Human Connectome Project, and was observed independently in data collected during performance of 7 task paradigms. The spatial distribution of Granger causality reflected vascular anatomy with a progression from Granger causality sources, in Circle of Willis arterial inflow distributions, to sinks, near large venous vascular structures such as dural venous sinuses and at the periphery of the brain. Attempts to resolve BOLD phase differences with Granger causality should consider the possibility of reproducible vascular confounds, a problem that is independent of the known regional variability of the hemodynamic response.

  8. Russian energy in the EU market: Bolstered institutionsand their effects

    International Nuclear Information System (INIS)

    2014-01-01

    The article examines institutional changes in EU–Russian energy relations since 2000. The article explores the ability of transformed institutions to limit the politicisation of energy and to reconcile the EU competitive-market approach with Russian state capitalism. More specifically, the article focuses on changes in intergovernmental, transgovernmental and transnational interactions. The article demonstrates that the gradual strengthening of transgovernmental and transnational institutions has inhibited the politicisation of energy relations and facilitated regulative cooperation between the EU and Russia. However, the potential of shared institutions is constrained by internal institutions on both sides. In Russia, these obstacles are insufficient top-down delegation of responsibilities in the government and its great power aspirations. In the EU, key barriers include inter-institutional rivalries, the EU’s propensity to impose its legislation on external partners and the integration of energy policy with foreign policy. The article presents several policy implications. First, it is futile to institutionally impose the regulative paradigm of one partner on the other; rather, mutual dialogue is needed. Thus, institutions should be structured appropriately. Second, current depoliticisation will require the involvement of not only the EU and Russia but also transit countries, such as Ukraine. Third, transgovernmental and transnational cooperation should be nurtured because this is a useful channel for both information exchange and a regulative convergence of policy implementing mechanisms. Finally, this incremental regulative convergence is the only option available today for the EU and Russia; this is also a way to further depoliticise energy relations. - Highlights: • EU and Russia developed transgovernmental and transnational energy institutions. • It allowed them to face energy challenges: depoliticisation and market construction. • Internal EU and

    We give a causal interpretation of stochastic differential equations (SDEs) by defining the postintervention SDE resulting from an intervention in an SDE. We show that under Lipschitz conditions, the solution to the postintervention SDE is equal to a uniform limit in probability of postintervention...... structural equation models based on the Euler scheme of the original SDE, thus relating our definition to mainstream causal concepts. We prove that when the driving noise in the SDE is a Lévy process, the postintervention distribution is identifiable from the generator of the SDE....

    1976-01-01

    It is shown that the set of timelike curves in a globally hyperbolic space-time manifold can be given the structure of a Hilbert manifold under a suitable definition of 'timelike.' The causal curves are the topological closure of this manifold. The Lorentzian energy (corresponding to Milnor's energy, except that the Lorentzian inner product is used) is shown to be a Morse function for the space of causal curves. A fixed end point index theorem is obtained in which a lower bound for the index of the Hessian of the Lorentzian energy is given in terms of the sum of the orders of the conjugate points between the end points.

    Convergent Cross-Mapping (CCM) has shown high potential to perform causal inference in the absence of models. We assess the strengths and weaknesses of the method by varying coupling strength and noise levels in coupled logistic maps. We find that CCM fails to infer accurate coupling strength...... and even causality direction in synchronized time-series and in the presence of intermediate coupling. We find that the presence of noise deterministically reduces the level of cross-mapping fidelity, while the convergence rate exhibits higher levels of robustness. Finally, we propose that controlled noise...

    Full Text Available The author assesses the impact of the Yuan exchange rate volatility on the indicators of the Russian-Chinese trade (the analysis is made on the ground of the statistical database CEIC. Quantitative estimates of changes in Russian-Chinese merchandise trade by commodity groups (in the HS classification due to the revaluation of the CNY against the USD were obtained via the regression analysis. In the case of the revaluation of the Yuan to the US dollar the value of Russian exports may increase for such commodity groups as mineral products, chemical industry products, base metals, precious stones and metals, and vehicles. This article shows that the value of Chinese imports will decrease for such merchandise groups as transport vehicles, machinery and equipment, leather industry products, non-precious metals and products from them; in this case, the import of the food industry products, mineral products and optical instruments will decrease insignificantly. The author concludes that the revaluation of the Yuan, contributing to the growth of Russian exports and the reduction in Chinese imports, will not cause a radical change in structure of the Russian-Chinese trade

  15. Russian oil prices: courting the world market

    1995-01-01

    The export and oil pricing of Russian crude was discussed. Russian crude and oil product exports are not yet wholly competitive with world oil markets. It was suggested that to do so, would be neither desirable nor actually possible at present. The reason for this is related to Russia's export duties regime and Russia's trade with its neighbouring countries which include the former Soviet republics. In the first half of 1995, the average border price of crude destined for those countries was US$75.04/tonne as opposed to US$114.77/tonne for crude exported to 'far-abroad', hard-currency markets. A breakdown of Russia's export duties for liquid fuels and a typical breakdown of export and domestic prices for Russian oil was provided. Russian crude is considerably under-priced mainly because of the poor state of the national refining industry which is in need of radical modernization. It was suggested that instead of globalization, it would be more appropriate to redirect the priorities of Russian energy policy towards defining optimal use of Russia's available energy potential, and rationalizing its domestic price structure first, which is the root cause of the national price problem. 5 refs., 5 tabs., 2 figs

    Full Text Available This study explored why and how Russian speaking parents in an Irish context maintained the Russian language in their school-age children. Using a self-administered unstandardised questionnaire, the opinions of 16 Russian-speaking parents, reporting on 24 children, were surveyed. Of this sample, five parents were then interviewed using focus group methodology. The main findings revealed that Russian-speaking parents living in Ireland strongly supported Russian language maintenance in their families and wanted their children to be as fluent as possible in the Russian language. The reasons for the support of Russian language were: cultural preservation, general knowledge of languages in addition to English, and communication with the homeland. Methods employed to maintain the Russian language included conversing with children through Russian, reading and watching Russian TV/DVD. Although most parents spoke only Russian to their children, just three children were considered by their parents to have sufficient language skills to interact through Russian in Russian speaking countries. Interestingly, 15 children were thought to have adequate skills in Russian to speak with those outside their immediate family when in Ireland. Congruent with other studies of bilingualism, development of English, or the secondary, majority language, was also important to parents, as they lived in a dominant English-speaking society.

    Full Text Available Russia was a regular participant of the World Expos and an organizer of several international exhibitions in Moscow, St.Petersburg and other Russian cities. The value of the Russia’s contribution into the history of the World Expos is substantial and versatile. Russia’s participation in the Universal Expositions produced a strong impact on the development of the exhibition economy, architecture, construction machinery, engineering, and urban development. In its turn, urbanization produced its impact on the development of Expos. Major Russian architects, sculptors and designers created exceptional and original works in a variety of styles; they employed versatile construction methods and techniques. Trade fairs served as the venues for experimental buildings constructed in furtherance of the most advanced designs and technology-related inventions. Russia’s participation in the construction of pavilions at the World Exhibitions gave way to a unique architectural trend, whereby three-dimensional solutions, the architecture of pavilions, landscape products, landscapes and even music got together in the organic unity. This artificial artistic medium represents a new type of the architectural ensemble.Отражено участие России во всемирных выставках, показана история строительства российских павильонов, раскрыты их архитектурные особенности в различные исторические периоды с XIX по XXI вв.

    2015-04-01

    After a period of extensive growth in the 2000's, the Russian gas industry is now facing numerous challenges. Mounting competition by independent producers and the development of new production by Gazprom, combined with stagnating domestic demand and weakening export markets, have created a situation of overproduction, made worse by western sanctions and low oil and gas prices. Expansion to the East thanks to the recent China deal is not expected to provide much relief before 2024. The coming decade will be critical for the industry and its outcome will largely depend on the government's pricing and institutional policies but the role of the state should remain essential. This document presents the key findings of the New CEDIGAZ report 'Russian Gas Market: Entering New Era'. The report analyses the ongoing changes in the Russian industry and the challenges to be met

    Full Text Available One of peculiar features of the military criminal justice system in Russia is that in some cases military defendants may apply for trial by jury. Unlike the existing U.S. court-martial jury and the Russian military jury of the early 1900s (World War I period which were comprised of the members of the armed forces, in modern Russia jurors trying military defendants are civilians. This article aims to provide a brief history of military jury in Russia and identify issues of independence and impartiality in Russian military courts with participation of lay decision-makers. In particular, the article will analyze two high-profile cases which resulted in acquittals of Russian officers accused of killing several Chechen civilians during counter-terrorist operations in Chechnya.

    2009-01-01

    This article intends to explain and evaluate the interactions between the three developments which have structured the Russian oil industry since the beginning of V. Putin's second presidential term of office: the slowing down in production growth as well as the absolute decline of the latter observed in 2008, the reorganization of this industry marked by the increasing role of public oil companies and, finally, the adjustments made to the contractual arrangements surrounding the activities of the upstream oil sector. It has shown, on one hand, that the decline in current production is the result of the exhaustion of short term strategies by private Russian companies, and on the other hand, that the contract adjustments are insufficient to allow the Russian companies to adjust to more long term strategies. From this perspective, the increased role played by public oil companies can be analysed as an organisational response to this institutional dead-end. (author)

    Full Text Available The paper gauges export demand elasticities for Russia using an Error Correction technique within a cointegration framework. An extended version of the Imperfect Substitutes Model has been implemented to estimate the sensitivity of Russian exports without oil components to price and to Russian and world income. Our results suggest a robust and negative long run cointegration relationship between the real effective exchange rate, defined as the weighted average of the rouble’s exchange rates versus a basket of the three currencies with the largest share in the trade turnover adjusted to incorporate inflation rate differences (the ratio of the domestic price indices to the foreign price indices, and Russian exports. An increase in exports by 24% is caused by a real depreciation by 10%. Furthermore, a 10% growth in world income leads to a 33% rise in exports. Finally, exports drop by 14% whenever a 10% increase in domestic income occurs

    Bonnefon, Jean-François; Sloman, Steven A

    2013-01-01

    The psychology of reasoning is increasingly considering agents' values and preferences, achieving greater integration with judgment and decision making, social cognition, and moral reasoning. Some of this research investigates utility conditionals, ''if p then q'' statements where the realization of p or q or both is valued by some agents. Various approaches to utility conditionals share the assumption that reasoners make inferences from utility conditionals based on the comparison between the utility of p and the expected utility of q. This article introduces a new parameter in this analysis, the underlying causal structure of the conditional. Four experiments showed that causal structure moderated utility-informed conditional reasoning. These inferences were strongly invited when the underlying structure of the conditional was causal, and significantly less so when the underlying structure of the conditional was diagnostic. This asymmetry was only observed for conditionals in which the utility of q was clear, and disappeared when the utility of q was unclear. Thus, an adequate account of utility-informed inferences conditional reasoning requires three components: utility, probability, and causal structure. Copyright © 2012 Cognitive Science Society, Inc.

    Different intuitive theories constrain and guide inferences in different contexts. Formalizing simple intuitive theories as probabilistic processes operating over structured representations, we present a new computational model of category-based induction about causally transmitted properties. A first experiment demonstrates undergraduates' context-sensitive use of taxonomic and food web knowledge to guide reasoning about causal transmission and shows good qualitative agreement between model predictions and human inferences. A second experiment demonstrates strong quantitative and qualitative fits to inferences about a more complex artificial food web. A third experiment investigates human reasoning about complex novel food webs where species have known taxonomic relations. Results demonstrate a double-dissociation between the predictions of our causal model and a related taxonomic model [Kemp, C., & Tenenbaum, J. B. (2003). Learning domain structures. In Proceedings of the 25th annual conference of the cognitive science society]: the causal model predicts human inferences about diseases but not genes, while the taxonomic model predicts human inferences about genes but not diseases. We contrast our framework with previous models of category-based induction and previous formal instantiations of intuitive theories, and outline challenges in developing a complete model of context-sensitive reasoning.

  14. A quantum probability model of causal reasoning

    Directory of Open Access Journals (Sweden)

    Jennifer S Trueblood

    2012-05-01

    Full Text Available People can often outperform statistical methods and machine learning algorithms in situations that involve making inferences about the relationship between causes and effects. While people are remarkably good at causal reasoning in many situations, there are several instances where they deviate from expected responses. This paper examines three situations where judgments related to causal inference problems produce unexpected results and describes a quantum inference model based on the axiomatic principles of quantum probability theory that can explain these effects. Two of the three phenomena arise from the comparison of predictive judgments (i.e., the conditional probability of an effect given a cause with diagnostic judgments (i.e., the conditional probability of a cause given an effect. The third phenomenon is a new finding examining order effects in predictive causal judgments. The quantum inference model uses the notion of incompatibility among different causes to account for all three phenomena. Psychologically, the model assumes that individuals adopt different points of view when thinking about different causes. The model provides good fits to the data and offers a coherent account for all three causal reasoning effects thus proving to be a viable new candidate for modeling human judgment.

    Schiefeneder, Daniela

    2011-01-01

    Causal variational principles are a class of nonlinear minimization problems which arise in a formulation of relativistic quantum theory referred to as the fermionic projector approach. This thesis is devoted to a numerical and analytic study of the minimizers of a general class of causal variational principles. We begin with a numerical investigation of variational principles for the fermionic projector in discrete space-time. It is shown that for sufficiently many space-time points, the minimizing fermionic projector induces non-trivial causal relations on the space-time points. We then generalize the setting by introducing a class of causal variational principles for measures on a compact manifold. In our main result we prove under general assumptions that the support of a minimizing measure is either completely timelike, or it is singular in the sense that its interior is empty. In the examples of the circle, the sphere and certain flag manifolds, the general results are supplemented by a more detailed analysis of the minimizers. (orig.)

  5. Scalar field Green functions on causal sets

    2017-01-01

    We examine the validity and scope of Johnston’s models for scalar field retarded Green functions on causal sets in 2 and 4 dimensions. As in the continuum, the massive Green function can be obtained from the massless one, and hence the key task in causal set theory is to first identify the massless Green function. We propose that the 2d model provides a Green function for the massive scalar field on causal sets approximated by any topologically trivial 2-dimensional spacetime. We explicitly demonstrate that this is indeed the case in a Riemann normal neighbourhood. In 4d the model can again be used to provide a Green function for the massive scalar field in a Riemann normal neighbourhood which we compare to Bunch and Parker’s continuum Green function. We find that the same prescription can also be used for de Sitter spacetime and the conformally flat patch of anti-de Sitter spacetime. Our analysis then allows us to suggest a generalisation of Johnston’s model for the Green function for a causal set approximated by 3-dimensional flat spacetime. (paper)

    2003-11-01

    Early adolescents may lack the cognitive and metacognitive skills necessary for effective inquiry learning. In particular, they are likely to have a nonnormative mental model of multivariable causality in which effects of individual variables are neither additive nor consistent. Described here is a software-based intervention designed to facilitate students' metalevel and performance-level inquiry skills by enhancing their understanding of multivariable causality. Relative to an exploration-only group, sixth graders who practiced predicting an outcome (earthquake risk) based on multiple factors demonstrated increased attention to evidence, improved metalevel appreciation of effective strategies, and a trend toward consistent use of a controlled comparison strategy. Sixth graders who also received explicit instruction in making predictions based on multiple factors showed additional improvement in their ability to compare multiple instances as a basis for inferences and constructed the most accurate knowledge of the system. Gains were maintained in transfer tasks. The cognitive skills and metalevel understanding examined here are essential to inquiry learning.

    2006-01-01

    Full Text Available Nike Corporation is one of leading global players in sports apparel and footwear market. Strategic development of Nike Co has always been based on superior marketing and engagement of world-class sportspersons in its advertising campaigns. When USSR collapsed, Nike immediately started with penetration on Russian market. By relying on its outstanding innovativeness in product development and marketing, Nike has become one of three biggest players in the market. As its distributor for Russian market, Nike has chosen Serbia-based company, Delta Sport. The strategy of penetration on Russian market is based on four major pillars: sport marketing, public relations retail marketing and advertising. The most relevant competitors on Russian market are Reebok and Adidas. Trying to increase its market share in the Russian Federation, Nike has used following competitive advantages: global brand, retail discounts and cost decrease. Regarding further development of the company's activities on Russian market, long-term objectives are as follows: maintaining the leading position, unfurling production on whole RF and CIS territories, new contracts and improvement of contracts with existing partners, expanding of retail network, establishment of own production on RF and CIS markets, and orientation of marketing department toward "Sport Marketing". Delta Sport, as an agent of Nike Co, has certain freedom in creating business policy but it still has to comply with basic principles adopted for the whole corporation. The most important factors considered when selecting a strategy are: positive sides of firm, its goals and interests top management relationships, financial resources, personnel qualifications influence of external environment, and time factor. Delta Sport has entirely adopted these principles and also developed internal ones, which are complementary with Nike's.

  10. Reducing Children’s Behavior Problems through Social Capital: A Causal Assessment

    2016-01-01

    Behavior problems among young children have serious detrimental effects on short and long-term educational outcomes. An especially promising prevention strategy may be one that focuses on strengthening the relationships among families in schools, or social capital. However, empirical research on social capital has been constrained by conceptual and causal ambiguity. This study attempts to construct a more focused conceptualization of social capital and aims to determine the causal effects of social capital on children’s behavior. Using data from a cluster randomized trial of 52 elementary schools, we apply several multilevel models to assess the causal relationship, including intent to treat and treatment on the treated analyses. Taken together, these analyses provide stronger evidence than previous studies that social capital improves children’s behavioral outcomes and that these improvements are not simply a result of selection into social relations but result from the social relations themselves.

    Full Text Available A study of employees’ loyalty to organization is usually associated with the analysis of the organizational culture, its norms, values, rules, which create a peculiar relationships the staff and the organization. In modern Russia there is an interesting symbiosis of the different epochs cultures, determining the personnel loyalty to organizations. The article represents the results of the researches received in the last decade by well-known Western and Russian sociological centers, as well as by some separate Russian sociologists. A significant feature of these studies is that they were conducted solely with the use of quantitative methods and in the format of Western corporate values and Western evaluation tools. The author research demonstrates that the corporate culture of Russian organizations, as well as the personnel loyalty, does not meet many inherent in international practice, evaluation criteria. Russian business culture is usually regarded as being in the process of becoming, to some extent, “underdeveloped” in comparison with the culture that exists in countries with strong capitalist traditions. This is not true. Over 25 years in Russia of market economy development have formed a certain system of values, incorporating values of pre-revolutionary business, ideological orientations of the Soviet era and the values that have been formed in recent years. Low degree of personnel’s loyalty towards the organizations, in this respect, is not a symptom of the cultural underdevelopment, it is a specific cultural trait of the domestic business, which has a quite rational basis and is not a subject to exclusively negative interpretation. This conclusion is based on the results of qualitative and quantitative research, conducted using methods of biographical analysis and content analysis of contemporary business periodicals. These qualitative and quantitative research methods in the analysis of the Russian corporate values determine a

  20. Nuclear energy and politics in Russian ATWS conditions

    1998-01-01

    Relations between politics and nuclear power in the countries of sustainable development has been many times discussed during the short history of nuclear energy, and regularly arising new events, even very important (in Sweden, USA, etc.), just add to the formed understanding of the problem. Russia for 10 years lives in conditions of a transition period, which seems similar to ATWS-type accidents at nuclear power plants. In these conditions the effect of politics on nuclear power and vice versa are seen very clearly, and, more important, change swiftly, which may present interest for the countries with smoother public processes. The role of political processes in nuclear power is obvious and may be reduced to three main factors: change of political system and transition to market economy have placed nuclear power, though still within state sector, in an absolutely new economic condition, which determine its today's situation as 'Survival'; new possibilities of political influence and opposition to nuclear power (mainly struggle against construction of new nuclear fuel cycle objects) on a levels of authority (local, regional, federal); impact of the USSR collapse on the situation in Russian nuclear power was due sooner to temporary weakening of control and regulatory structures, than to the fact, that some fuel cycle elements have found themselves abroad (the factor of uranium resources' loss is unimportant at present). Nuclear safety was chosen to be the subject of Moscow 1996 Summit, initiated with the purpose of Russia coming closer to G7. The Summit has confirmed the thesis on the possibility of nuclear power o play an important role in the world energy demand in accordance with sustainable development goals. successful activities of Russia-USA Commission for economic and technological cooperation, known as 'Gore-Chernomyrdin' Commission, is to a large extent determined by positive nuclear decisions.

    International Nuclear Information System (INIS)

    2009-11-01

    The primary goal of the Russian Research Reactor Fuel Return (RRRFR) programme is to advance nuclear non-proliferation objectives by eliminating stockpiles of Russian-origin highly enriched uranium (HEU). The RRRFR programme was first conceived during trilateral discussions among the USA, the Russian Federation and the IAEA, initiated in 1999, when participants identified more than 20 research reactors in 17 countries having Russian/Soviet supplied fuel. In 2000, the Director General of the IAEA sent a letter to 15 countries asking for their willingness to return HEU spent fuel to the Russian Federation. Fourteen countries responded positively to the Director General's letter. In 2004, the Russian Federation and the USA signed a Government-to-Government Agreement concerning cooperation to return the Russian produced research reactor nuclear fuel to the Russian Federation. This agreement established the legal framework necessary for the cooperation between the Russian Federation and the USA for the return of Russian supplied research reactor fuel from eligible countries. Under the Bratislava agreements concluded by Presidents George W. Bush and Vladimir Putin in February 2005, both countries committed to completing all shipments of Russian-origin HEU spent fuel currently stored outside research reactors by the end of 2010. Up to the time of writing (May 2009) the programme has completed 19 shipments totalling over 838 kg of Russian-origin HEU spent and fresh fuel which has been returned from Bulgaria, the Czech Republic, Germany, Kazakhstan, Latvia, the Libyan Arab Jamahiriya, Poland, Romania, Serbia, Uzbekistan and Vietnam. During this time, the programme successfully removed all HEU from two countries, Latvia and Bulgaria. HEU spent fuel shipments have been the most complex shipments under the RRRFR programme, which will be the focus of this publication. The first shipment of HEU spent fuel from Uzbekistan was completed in January 2006, followed by HEU spent fuel

  2. Pairwise measures of causal direction in the epidemiology of sleep problems and depression.

    Directory of Open Access Journals (Sweden)

    Tom Rosenström

    Full Text Available Depressive mood is often preceded by sleep problems, suggesting that they increase the risk of depression. Sleep problems can also reflect prodromal symptom of depression, thus temporal precedence alone is insufficient to confirm causality. The authors applied recently introduced statistical causal-discovery algorithms that can estimate causality from cross-sectional samples in order to infer the direction of causality between the two sets of symptoms from a novel perspective. Two common-population samples were used; one from the Young Finns study (690 men and 997 women, average age 37.7 years, range 30-45, and another from the Wisconsin Longitudinal study (3101 men and 3539 women, average age 53.1 years, range 52-55. These included three depression questionnaires (two in Young Finns data and two sleep problem questionnaires. Three different causality estimates were constructed for each data set, tested in a benchmark data with a (practically known causality, and tested for assumption violations using simulated data. Causality algorithms performed well in the benchmark data and simulations, and a prediction was drawn for future empirical studies to confirm: for minor depression/dysphoria, sleep problems cause significantly more dysphoria than dysphoria causes sleep problems. The situation may change as depression becomes more severe, or more severe levels of symptoms are evaluated; also, artefacts due to severe depression being less well presented in the population data than minor depression may intervene the estimation for depression scales that emphasize severe symptoms. The findings are consistent with other emerging epidemiological and biological evidence.

    Gagarinski, A.Yu.

    2003-01-01

    After the nuclear criticality had been reached on a uranium-graphite assembly for the first time in the Soviet Union on December 25, 1946, by I.V. Kurchatov and his team (1), the critical conditions in a great variety of multiplying media have been realized only in the Kurchatov Institute for at least several thousand times. Even the first Russian critical experiments carried out by Igor Kurchatov confirmed the unique merits of zero-power reactors: the most practically convenient range of parameters of kinetic response for variation of critical conditions, as well as invariability, over a wide range of the most important functions of neutron flux to reactor power. Neutron physics experiments have become a necessary stage in creation and improvement of nuclear reactors. Most critical experiments were performed mainly as a necessary stage of reactor design in the 60ies and 70ies, which has been the reactor 'golden age', when most of the total of over thousand nuclear reactors of various type and destination have been created worldwide. Though the ways of conducting critical measurements were very diversified, there are two main types of experiments. The first is so-called mock-up or prototype experiments when an exact (to the extent possible) simulation of the core is constructed to minimize the error in forecasting the operating reactor characteristics. Such experiments, which often represent the quality control of the core manufacturing and adjustment of core parameters to the design requirements, were carried out in Russia on critical assemblies of several plants, in design institutions (OKBM, Nizhni Novgorod; Electrostal and others), as well as in research centers (RRC 'Kurchatov Institute', etc.). Their results, which prevail today in the criticality database, even taking into account the capabilities provided by present-day calculation codes, are not well suited for new applications. It is hard to expect that the error resulting from inevitable idealization of

    The vast majority of the work on culture and cognition has focused on cross-cultural comparisons, largely ignoring the dynamic aspects of culture. In this article, we provide a diachronic analysis of causal cognition over time. We hypothesized that the increased role of education, science, and technology in Western societies should be accompanied by greater attention to causal connections. To test this hypothesis, we compared word frequencies in English texts from different time periods and found an increase in the use of causal language of about 40% over the past two centuries. The observed increase was not attributable to general language effects or to changing semantics of causal words. We also found that there was a consistent difference between the 19th and the 20th centuries, and that the increase happened mainly in the 20th century. © The Author(s) 2016.

    This study was conducted to investigate the relation between hopelessness and causal attribution in Japanese school-aged children. In Study 1, the Japanese edition of hopelessness scale for children developed by Kazdin, French, Unis, Esveldt-Dawsan, and Sherick (1983) was constructed. Seventeen original items were translated into Japanese and they were administrated to 405 fifth- and sixth-graders. All of the items could be included to the Japanese edition of hopelessness scale. The reliability and validity was examined. In Study 2, the relation between hopelessness and causal attribution in children were investigated. The causal attribution questionnaire developed by Higuchi, Kambare, and Otsuka (1983) and the hopelessness scale developed by Study 1 were administered to 188 sixth-graders. Children with high scores in hopelessness scale significantly attributed negative events to much more effort factor than children with low scores. It supports neither the reformulated learned helplessness model nor the causal attribution theory of achievement motivation. It was explained mainly from points of self-serving attribution, cultural difference, and social desirability. Some questions were discussed for developing studies on depression and causal attribution in Japan.

  9. Best Practices for Gauging Evidence of Causality in Air Pollution Epidemiology.

    Science.gov (United States)

    Dominici, Francesca; Zigler, Corwin

    2017-12-15

    The contentious political climate surrounding air pollution regulations has brought some researchers and policy-makers to argue that evidence of causality is necessary before implementing more stringent regulations. Recently, investigators in an increasing number of air pollution studies have purported to have used "causal analysis," generating the impression that studies not explicitly labeled as such are merely "associational" and therefore less rigorous. Using 3 prominent air pollution studies as examples, we review good practices for how to critically evaluate the extent to which an air pollution study provides evidence of causality. We argue that evidence of causality should be gauged by a critical evaluation of design decisions such as 1) what actions or exposure levels are being compared, 2) whether an adequate comparison group was constructed, and 3) how closely these design decisions approximate an idealized randomized study. We argue that air pollution studies that are more scientifically rigorous in terms of the decisions made to approximate a randomized experiment are more likely to provide evidence of causality and should be prioritized among the body of evidence for regulatory review accordingly. Our considerations, although presented in the context of air pollution epidemiology, can be broadly applied to other fields of epidemiology. © The Author(s) 2017.

  11. Empirical reality, empirical causality, and the measurement problem

    International Nuclear Information System (INIS)

    d'Espagnat, B.

    1987-01-01

    Does physics describe anything that can meaningfully be called independent reality, or is it merely operational? Most physicists implicitly favor an intermediate standpoint, which takes quantum physics into account, but which nevertheless strongly holds fast to quite strictly realistic ideas about apparently obvious facts concerning the macro-objects. Part 1 of this article, which is a survey of recent measurement theories, shows that, when made explicit, the standpoint in question cannot be upheld. Part 2 brings forward a proposal for making minimal changes to this standpoint in such a way as to remove such objections. The empirical reality thus constructed is a notion that, to some extent, does ultimately refer to the human means of apprehension and of data processing. It nevertheless cannot be said that it reduces to a mere name just labelling a set of recipes that never fail. It is shown that their usual notion of macroscopic causality must be endowed with similar features

The methodology used in the research of peer effect relies on the theory of predicting error, the signal which measures changes in anticipation of the net present value which generates new information. Cognitive neuroscience shows that the prediction error is measured in a certain part of the brain known as the ventral striatum. Measuring the potential value gives insights to economists on which factors affecting the subjective utility. Testing is constructed with 48 patients who were given $ 100 of experimental money and they were given the opportunity to invest in two separate assets in over two hundred experiments. The experiment showed that subjects converted their final portfolio from experimental currency to real dollars using the exchange rate of 5: 1. In addition to profits from the experiment, subjects were paid a fixed "show-up" fee of $ 20. There are two difficulties in identifying causal peer effect in economic behavior (Minsk, 1993. Correlated behavior between two representatives may potentially be the engine by common shocks of the peer group or endogenous election in the peer group. In addition to the prediction that deals with causal peer effect, there have been further developed predictions that generate different mechanisms of peer effects using neural database. Focus on neural prediction is the neural activity that generates the moment when peers allocation investment is published

Children (5-, 8-, and 12-year-olds) and adults were given trials in which they decided whether a property known to be possessed by members of one category was also possessed by members of (a) a taxonomically related category or (b) a causally related category. The direction of the causal link was either predictive (prey→predator) or diagnostic (predator→prey), and the property that participants reasoned about established either a taxonomic or causal context. There was a causal asymmetry effect across all age groups, with more causal choices when the causal link was predictive than when it was diagnostic. Furthermore, context-sensitive causal reasoning showed a curvilinear development, with causal choices being most frequent for 8-year-olds regardless of context. Causal inductions decreased thereafter because 12-year-olds and adults made more taxonomic choices when reasoning in the taxonomic context. These findings suggest that simple causal relations may often be the default knowledge structure in young children's inductive reasoning, that sensitivity to causal direction is present early on, and that children over-generalize their causal knowledge when reasoning.

    In this paper we empirically investigate the causal link between energy consumption and economic growth employing a Markov switching Granger causality analysis. We carry out our investigation using annual U.S. real GDP, total final energy consumption and total primary energy consumption data which cover the period between 1968 and 2010. We find that there are significant changes in the causal relation between energy consumption and economic growth over the sample period under investigation. Our results show that total final energy consumption and total primary energy consumption have significant predictive content for real economic activity in the U.S. economy. Furthermore, the causality running from energy consumption to output growth seems to be strongly apparent particularly during the periods of economic downturn and energy crisis. We also document that output growth has predictive power in explaining total energy consumption. Furthermore, the power of output growth in predicting total energy consumption is found to diminish after the mid of 1980s. - Highlights: • Total energy consumption has predictive content for real economic activity. • The causality from energy to output growth is apparent in the periods of recession. • The causality from energy to output growth is strong in the periods of energy crisis. • Output growth has predictive power in explaining total energy consumption. • The power of output growth in explaining energy diminishes after the mid of 1980s

    Sagen, Eirik Lund; Tsygankova, Marina

    2008-01-01

    In this paper we use both theoretical and numerical tools to study potential effects on Russian gas exports from different Russian domestic gas prices and production capacities in 2015. We also investigate whether a fully competitive European gas market may provide incentives for Gazprom, the dominant Russian gas company, to change its export behaviour. Our main findings suggest that both increased domestic gas prices and sufficient production capacities are vital to maintain Gazprom's market share in Europe over the next decade. In fact, Russia may struggle to carry out its current long-term export commitments if domestic prices are sufficiently low. At the same time, if Russian prices approach European net-back levels, Gazprom may reduce exports in favour of a relatively more profitable domestic market

  2. Nuclear energy and society: Russian dimension

    International Nuclear Information System (INIS)

    Gagarinski, A.Y.

    2010-01-01

    Nuclear weapons and crisis of confidence resulting from severe accidents have both formed the attitude towards nuclear issues in the Russian minds. The current status of relations between nuclear energy and the public is still close to this politicization of nuclear energy and to the constant irrational fear of radiations. The 3 basic antinuclear arguments usually mentioned are proliferation risk, wastes and accidents. For proliferation risk it is easy to understand that a complete nuclear power phase-out would not prevent the spreading of nuclear weapons because uranium and centrifuges would still exist. For the Russian society, the issue of radioactive wastes is popular these days because the Russian parliament is considering a bill about it. The issue of radioactive wastes seems to be economically and technically solvable. The main problem is nuclear accidents. In Russia this issue is very touchy: we still remember zero-radiation events, which, when happened not very long ago, have aroused panics in whole regions. It is hard to change the idea, well spread in Russian minds that the authorities are always trying to understate the scale of negative events. Nevertheless, some recent polls show that the positive trend in the attitude towards nuclear energy is obvious as it is in most part of the world. (A.C.)

    Full Text Available The use of antiepileptic drugs (AEDs during pregnancy is associated with an increased risk of congenital malformations (CMF. Information on the teratogenicity of AEDs is contradictory. The potential negative effects of new-generation AEDs are less well known. Many physicians and patients face difficulties in establishing a balance between the risk of seizures during pregnancy and that of teratogenicity in the use of AEDs. In most foreign countries, there are national and international pregnancy and epilepsy registries that make possible to centralize and systematize information on the safety of AEDs and to also give a true picture of the state of the problem.The Russian pregnancy and epilepsy register (RPER has been launched since 2017. RPER is a Russian national prospective and retrospective observational study, without interfering with the antiepileptic therapy prescribed by an attending physician to childbearing-aged patients living in the subjects of the Russian Federation. RPER is an independent research initiative and is implemented by neurologists and psychiatrists who provide assistance to women with epilepsy. The main goal of the RPER is to compare the risk of serious CMFs following the maternal intake of various AEDs and their combinations in different regions of the Russian Federation and to develop strategies for preventing CMFs.

    Full Text Available Objective basing on the research of formation and development of the administrative prejudgment in the Russian criminal law and comparativelegal analysis of this institution as well as the longterm experience in crime investigation to trace the problems and trends of administrative prejudgment and prove the necessity to introduce or to be more precise legalize the administrative prejudgment in the Russian criminal law. Methods the research is based on the general dialectic method of cognition comparative historical formaljuridical methods as well as special and privatelegal methods of research. Results analysis of the main problems and collisions of administrative prejudgment in the Russian criminal law the doctrine and the practice of implementation of this institution can become the basis for legalization of the administrative prejudgment in the Russian criminal law and implementing it for the crimes stipulated in the Special part of the Russian Criminal Code if they are of low or middle gravity and committed intentionally those most often occurred. The article studies the institution of the administrative prejudgment in the Russian criminal law since 1922 until present. Various researchersrsquo opinions are given for and against returning of this institution. Taking into account the criminological indicators the authors express their own opinion on legalization of the administrative prejudgment. Scientific novelty having abandoned the formal approach to the institution of the administrative prejudgment both in the Russian criminal law and in the foreign laws the authors believe that the criminal personality should be the central factor of the administrative prejudgment legalization. In this context the authors state the direct connection between the personal features of a criminal including their inclination to immoral and illegal behavior and the crime committed by them. Practical value the theoretical conclusions formulated in the research

    The technology of a monolithic construction is a well-established practice among most Russian real estate developers. The strong points of the technology are low cost of materials and lower demand for qualified workers. The monolithic construction uses various types of reinforced slabs and foamed concrete, since they are easy to use and highly durable; they also need practically no additional treatment.
