With one exception, these papers are original and fully refereed research articles on various applications of Category Theory to Algebraic Topology, Logic and Computer Science. The exception is an outstanding and lengthy survey paper by Joyal/Street (80 pp) on a growing subject: it gives an account of classical Tannaka duality in such a way as to be accessible to the general mathematical reader, and to provide a key for entry to more recent developments and quantum groups. No expertise in either representation theory or category theory is assumed. Topics such as the Fourier cotransform, Tannaka duality for homogeneous spaces, braided tensor categories, Yang-Baxter operators, Knot invariants and quantum groups are introduced and studies.

Measures in the context of Category Theory lead to various relations, even differential relations, of categories that are independent of the mathematical structure forming objects of a category. Such relations, which are independent of the mathematical structure that we may represent a physical body or a system of reference with, are, precisely, demanded to be the Laws of Physics by the General Principle of Relativity.

Fusion categories and homotopy theory
Etingof, Pavel; Ostrik, Victor
2009-01-01
We apply the yoga of classical homotopy theory to classification problems of G-extensions of fusion and braided fusion categories, where G is a finite group. Namely, we reduce such problems to classification (up to homotopy) of maps from BG to classifiying spaces of certain higher groupoids. In particular, to every fusion category C we attach the 3-groupoid BrPic(C) of invertible C-bimodule categories, called the Brauer-Picard groupoid of C, such that equivalence classes of G-extensions of C are in bijection with homotopy classes of maps from BG to the classifying space of BrPic(C). This gives rise to an explicit description of both the obstructions to existence of extensions and the data parametrizing them; we work these out both topologically and algebraically. One of the central results of the paper is that the 2-truncation of BrPic(C) is canonically the 2-groupoid of braided autoequivalences of the Drinfeld center Z(C) of C. In particular, this implies that the Brauer-Picard group BrPic(C) (i.e., the grou...

Requirement volatility is an issue in software engineering in general, and in Web-based clinical applications in particular, which often originates from an incomplete knowledge of the domain of interest. With advances in the health science, many features and functionalities need to be added to, or removed from, existing software applications in the biomedical domain. At the same time, the increasing complexity of biomedical systems makes them more difficult to understand, and consequently it is more difficult to define their requirements, which contributes considerably to their volatility. In this paper, we present a novel agent-based approach for analyzing and managing volatile and dynamic requirements in an ontology-driven laboratory information management system (LIMS) designed for Web-based case reporting in medical mycology. The proposed framework is empowered with ontologies and formalized using category theory to provide a deep and common understanding of the functional and nonfunctional requirement hi...
Comparing operadic theories of $n$-categories
Cheng, Eugenia
2008-01-01
We give a framework for comparing on the one hand theories of n-categories that are weakly enriched operadically, and on the other hand n-categories given as algebras for a contractible globular operad. Examples of the former are the definition by Trimble and variants (Cheng-Gurski) and examples of the latter are the definition by Batanin and variants (Leinster). We will show how to take a theory of n-categories of the former kind and produce a globular operad whose algebras are the n-categories we started with. We first provide a generalisation of Trimble's original theory that allows for the use of other parametrising operads in a very general way, via the notion of categories weakly enriched in V where the weakness is parametrised by an operad P in the category V. We define weak n-categories by iterating the weak enrichment construction using a series of parametrising operads P_i. We then show how to construct from such a theory an n-dimensional globular operad for each $n \\geq 0$ whose algebras are precis...
Algebraic Theories and (Infinity,1)-Categories
Cranch, James
2010-11-01
We adapt the classical framework of algebraic theories to work in the setting of (infinity,1)-categories developed by Joyal and Lurie. This gives a suitable approach for describing highly structured objects from homotopy theory. A central example, treated at length, is the theory of E_infinity spaces: this has a tidy combinatorial description in terms of span diagrams of finite sets. We introduce a theory of distributive laws, allowing us to describe objects with two distributing E_infinity stuctures. From this we produce a theory of E_infinity ring spaces. We also study grouplike objects, and produce theories modelling infinite loop spaces (or connective spectra), and infinite loop spaces with coherent multiplicative structure (or connective ring spectra). We use this to construct the units of a grouplike E_infinity ring space in a natural manner. Lastly we provide a speculative pleasant description of the K-theory of monoidal quasicategories and quasicategories with ring-like structures.
Morita homotopy theory of C*-categories
Dell'Ambrogio, Ivo
2011-01-01
In this article we establish the foundations of the Morita homotopy theory of C*-categories. Concretely, we construct a cofibrantly generated simplicial symmetric monoidal Quillen model structure M_Mor on the category C*cat1 of small unital C*-categories. The weak equivalences are the Morita equivalences and the cofibrations are the *-functors which are injective on objects. As an application, we obtain an elegant description of the Brown-Green-Rieffel Picard group in the associated Morita homotopy category Ho(M_Mor). We then prove that the Morita homotopy category is semi-additive. By group completing the induced abelian monoid structure at each Hom-set we obtain an additive category Ho(M_Mor)^{-1} and a canonical functor C*cat1 {\\to} Ho(M_Mor)^{-1} which is characterized by two simple properties: inversion of Morita equivalences and preservation of all finite products. Finally, we prove that the classical Grothendieck group functor becomes co-represented in Ho(M_Mor)^{-1} by the tensor unit object.
Nel's category theory based differential and integral Calculus, or did Newton know category theory ?
Rosinger, Elemer Elad
2005-01-01
In a series of publications in the early 1990s, L D Nel set up a study of non-normable topological vector spaces based on methods in category theory. One of the important results showed that the classical operations of derivative and integral in Calculus can in fact be obtained by a rather simple construction in categories. Here we present this result in a concise form. It is important to note that the respective differentiation does not lead to any so called generalized derivatives, for inst...
Conciliating neuroscience and phenomenology via category theory.
Ehresmann, Andrée C; Gomez-Ramirez, Jaime
2015-12-01
The paper discusses how neural and mental processes correlate for developing cognitive abilities like memory or spatial representation and allowing the emergence of higher cognitive processes up to embodied cognition, consciousness and creativity. It is done via the presentation of MENS (for Memory Evolutive Neural System), a mathematical methodology, based on category theory, which encompasses the neural and mental systems and analyzes their dynamics in the process of 'becoming'. Using the categorical notion of a colimit, it describes the generation of mental objects through the iterative binding of distributed synchronous assemblies of neurons, and presents a new rationale of spatial representation in the hippocampus (Gómez-Ramirez and Sanz, 2011). An important result is that the degeneracy of the neural code (Edelman, 1989) is the property allowing for the formation of mental objects and cognitive processes of increasing complexity order, with multiple neuronal realizabilities; it is essential "to explain certain empirical phenomena like productivity and systematicity of thought and thinking (Aydede 2010)". Rather than restricting the discourse to linguistics or philosophy of mind, the formal methods used in MENS lead to precise notions of Compositionality, Productivity and Systematicity, which overcome the dichotomic debate of classicism vs. connectionism and their multiple facets. It also allows developing the naturalized phenomenology approach asked for by Varela (1996) which "seeks articulations by mutual constraints between phenomena present in experience and the correlative field of phenomena established by the cognitive sciences", while avoiding their pitfalls.

Multitensor lifting and strictly unital higher category theory
Batanin, Michael; Cisinski, Denis-Charles; Weber, Mark
2013-01-01
In this article we extend the theory of lax monoidal structures, also known as multitensors, and the monads on categories of enriched graphs that they give rise to. Our first principal result -- the lifting theorem for multitensors -- enables us to see the Gray tensor product of 2-categories and the Crans tensor product of Gray categories as part of this framework. We define weak n-categories with strict units by means of a notion of reduced higher operad, using the theory of algebraic weak f...
Non-connective K-theory of relative exact categories
Mochizuki, Satoshi
2013-01-01
The main objective of this paper is to propose a definition of non-connective K-theory for a wide class of relative exact categories which, in general, do not satisfy the factorization axiom and confirm that it agrees with the non-connective K-theory for exact categories and complicial exact categories with weak equivalences. The main application is to study the topological filtrations of non-connective K-theory of a noetherian commutative ring with unit in terms of Koszul cubes.
On Self-Predicative Universals in Category Theory
Ellerman, David
2014-01-01
1. This paper shows how the universals of category theory in mathematics provide a model (in the Platonic Heaven of mathematics) for the self-predicative strand of Plato's Theory of Forms as well as for the idea of a "concrete universal" in Hegel and similar ideas of paradigmatic exemplars in ordinary thought. 2. The paper also shows how the always-self-predicative universals of category theory provide the "opposite bookend" to the never-self-predicative universals of iterative set theory and...

Variation of geometric invariant theory quotients and derived categories
Ballard, Matthew; Katzarkov, Ludmil
2012-01-01
We develop a framework for studying the relationship between bounded derived categories of coherent sheaves on smooth global quotient stacks related by variations of the linearization in geometric invariant theory. We extend this framework to cover derived categories of coherent (matrix) factorizations when the stacks are equipped with potentials. Under assumptions on the variation, we provide simple numerical conditions for the derived categories to be related by semi-orthogonal decompositions. We also describe the complementary components in these semi-orthogonal decompositions. The results are applied to obtain a simple inductive description of derived categories of coherent sheaves on smooth and projective toric Deligne-Mumford stacks. We also show how the semi-orthogonal decompositions for derived categories of coherent factorizations fully generalize the commutative case of Orlov's $\\sigma$-model/Landau-Ginzburg theorem. In addition, we present examples to show close ties with Homological Projective Dua...
A KIF Formalization for the IFF Category Theory Ontology
Kent, Robert E
2011-01-01
This paper begins the discussion of how the Information Flow Framework can be used to provide a principled foundation for the metalevel (or structural level) of the Standard Upper Ontology (SUO). This SUO structural level can be used as a logical framework for manipulating collections of ontologies in the object level of the SUO or other middle level or domain ontologies. From the Information Flow perspective, the SUO structural level resolves into several metalevel ontologies. This paper discusses a KIF formalization for one of those metalevel categories, the Category Theory Ontology. In particular, it discusses its category and colimit sub-namespaces.
Categorial compositionality: a category theory explanation for the systematicity of human cognition.
Phillips, Steven; Wilson, William H
2010-01-01
Classical and Connectionist theories of cognitive architecture seek to explain systematicity (i.e., the property of human cognition whereby cognitive capacity comes in groups of related behaviours) as a consequence of syntactically and functionally compositional representations, respectively. However, both theories depend on ad hoc assumptions to exclude specific instances of these forms of compositionality (e.g. grammars, networks) that do not account for systematicity. By analogy with the Ptolemaic (i.e. geocentric) theory of planetary motion, although either theory can be made to be consistent with the data, both nonetheless fail to fully explain it. Category theory, a branch of mathematics, provides an alternative explanation based on the formal concept of adjunction, which relates a pair of structure-preserving maps, called functors. A functor generalizes the notion of a map between representational states to include a map between state transformations (or processes). In a formal sense, systematicity is a necessary consequence of a higher-order theory of cognitive architecture, in contrast to the first-order theories derived from Classicism or Connectionism. Category theory offers a re-conceptualization for cognitive science, analogous to the one that Copernicus provided for astronomy, where representational states are no longer the center of the cognitive universe--replaced by the relationships between the maps that transform them.

Understanding visualization: a formal approach using category theory and semiotics.
Vickers, Paul; Faith, Joe; Rossiter, Nick
2013-06-01
This paper combines the vocabulary of semiotics and category theory to provide a formal analysis of visualization. It shows how familiar processes of visualization fit the semiotic frameworks of both Saussure and Peirce, and extends these structures using the tools of category theory to provide a general framework for understanding visualization in practice, including: Relationships between systems, data collected from those systems, renderings of those data in the form of representations, the reading of those representations to create visualizations, and the use of those visualizations to create knowledge and understanding of the system under inspection. The resulting framework is validated by demonstrating how familiar information visualization concepts (such as literalness, sensitivity, redundancy, ambiguity, generalizability, and chart junk) arise naturally from it and can be defined formally and precisely. This paper generalizes previous work on the formal characterization of visualization by, inter alia, Ziemkiewicz and Kosara and allows us to formally distinguish properties of the visualization process that previous work does not.

Deformation theory of objects in homotopy and derived categories I: general theory
Efimov, Alexander I.; Lunts, Valery A.; Orlov, Dmitri O.
2007-01-01
This is the first paper in a series. We develop a general deformation theory of objects in homotopy and derived categories of DG categories. Namely, for a DG module $E$ over a DG category we define four deformation functors $\\Def ^{\\h}(E)$, $\\coDef ^{\\h}(E)$, $\\Def (E)$, $\\coDef (E)$. The first two functors describe the deformations (and co-deformations) of $E$ in the homotopy category, and the last two - in the derived category. We study their properties and relations. These functors are def...
The cobordism category and Waldhausen's K-theory
DEFF Research Database (Denmark)
Bökstedt, M.; Madsen, Ib
This paper examines the category C^k_{d,n} whose morphisms are d-dimensional smooth manifolds that are properly embedded in the product of a k-dimensional cube with an (d+n-k)-dimensional Euclidean space. There are k directions to compose k-dimensional cubes, so C^k_{d,n} is a (strict) k......-tuple category. The geometric realization of the k-dimensional multi-nerve is the classifying space BC^k_{d,n}. At the end of the paper we construct an infinite loop map to Waldhausens K-theory. \\Omega BC^1_{d,n}-> A(BO(d)), We believe that the map factors through \\Omega^\\infty\\Sigma^\\infty(BO(d)_+) and that the...
A model theoretic Baire category theorem for simple theories
Shami, Ziv
2009-01-01
We define the class of $\\tilde\\tau_{low}^f$-sets. This is a class of type-definable sets defined in terms of forking by low formulas. We prove a model theoretic Baire category theorem for $\\tilde\\tau_{low}^f$-sets in a countable simple theory in which the extension property is first-order and show some of its applications. A typical application is the following. Let $T$ be a countable theory with the wnfcp (weak nonfinite cover property) and assume for every non-algebraic $a$ there exists a non-algebraic $a'\\acl(a)$ such that $SU(a')<\\omega$. Then there exists a weakly-minimal formula with parameters.
Internalization theory: an unfinished agenda
Casson, Mark; Porter, Lynda; Wadeson, Nigel
2016-01-01
Internalization theory is usually applied at the firm level to analyse FDI, licensing and subcontracting, but this paper extends it to the industry level. It synthesises internalisation theory and oligopoly theory. It analyses a global industry where firms innovate competitively, and freely enter and exit the industry. It presents a formal model which highlights the inter-dependencies between rival firms. Each firm responds to its rivals by jointly optimising production and innovation through...
Limits of generalization between categories and implications for theories of category specificity.
Bukach, Cindy M; Phillips, W Stewart; Gauthier, Isabel
2010-10-01
Both domain-specific and expertise accounts of category specialization assume that generalization occurs within a domain but not between domains. Yet it is often difficult to define the boundaries and critical features of object domains. Differences in how categories are defined make it difficult to adjudicate between accounts of category specificity and may lead to contradictory results. For example, evidence for whether car experts recruit the fusiform face area is mixed, and this inconsistency may be due to the inclusion of antique cars in one of those previous studies (e.g., Grill-Spector, Knouf, & Kanwisher, 2004). The present study tested the generalization of expertise from modern to antique cars and found that modern-car experts showed expert discrimination and holistic processing of modern cars but not of antique cars. These findings suggest that the neural specialization underlying perceptual expertise is highly specific and may not generalize to distinct subclasses, even when they share some degree of perceptual and conceptual features.

Drinfeld Center and Representation Theory for Monoidal Categories
Neshveyev, Sergey; Yamashita, Makoto
2016-07-01
Motivated by the relation between the Drinfeld double and central property (T) for quantum groups, given a rigid C*-tensor category {{C}} and a unitary half-braiding on an ind-object, we construct a *-representation of the fusion algebra of {{C}}. This allows us to present an alternative approach to recent results of Popa and Vaes, who defined C*-algebras of monoidal categories and introduced property (T) for them. As an example we analyze categories {{C}} of Hilbert bimodules over a II1-factor. We show that in this case the Drinfeld center is monoidally equivalent to a category of Hilbert bimodules over another II1-factor obtained by the Longo-Rehren construction. As an application, we obtain an alternative proof of the result of Popa and Vaes stating that property (T) for the category defined by an extremal finite index subfactor {N subset M} is equivalent to Popa's property (T) for the corresponding SE-inclusion of II1-factors. In the last part of the paper we study Müger's notion of weakly monoidally Morita equivalent categories and analyze the behavior of our constructions under the equivalence of the corresponding Drinfeld centers established by Schauenburg. In particular, we prove that property (T) is invariant under weak monoidal Morita equivalence.

Equivariant Homotopy Theory and K-Theory of Exact Categories with Duality
DEFF Research Database (Denmark)
Moi, Kristian Jonsson
This thesis has two main parts. The first part, which consists of two papers, is concerned with the role of equivariant loop spaces in the K-theory of exact categories with duality. We prove a group completion-type result for topological monoids with anti-involution. The methods in this proof also...... apply in the context of K-theory and we obtain a similar result there. We go on to prove equivairant delooping results for Hesselholt and Madsen's Real algebraic K-theory. From these we obtain an equivalence of the fixed points of Real algebraic K-theory with Schlichting's Grothendieck-Witt space. This...... equivalence implies a group completion result for Grothendieck-Witt-theory, and for Real algebraic K-theory it implies that the analogs of the Conalty and Devissage theorems hold.The second part of the thesis, which consists of one paper, is about the equivariant homotopy theory of so-called G-diagrams.

The Role of Internal Reference Points in the Category Purchase Decision.
Bell, David R.; Randolph E. Bucklin
1999-01-01
The authors study the role that reference effects play in the category purchase decision for consumer nondurable products. Category purchase behavior is represented by a nested logit model that is estimated on purchase records of shoppers in two Universal Product Code (UPC) scanner panels. A series of hypotheses are developed, modeled, and tested regarding the effects that internal reference points for product category attractiveness are likely to have on the decision to buy in a product cate...

Logarithmic conformal field theory, log-modular tensor categories and modular forms
Creutzig, Thomas
2016-01-01
The two pillars of rational conformal field theory and rational vertex operator algebras are modularity of characters on the one hand and its interpretation of modules as objects in a modular tensor category on the other one. Overarching these pillars is the Verlinde formula. In this paper we consider the more general class of logarithmic conformal field theories and $C_2$-cofinite vertex operator algebras. We suggest that their modular pillar are trace functions with insertions corresponding to intertwiners of the projective cover of the vacuum, and that the categorical pillar are finite tensor categories $\\mathcal C$ which are ribbon and whose double is isomorphic to the Deligne product $\\mathcal C\\otimes \\mathcal C^{opp}$. Overarching these pillars is then a logarithmic variant of Verlinde's formula. Numerical data realizing this are the modular $S$-matrix and modified traces of open Hopf links. The representation categories of $C_2$-cofinite and logarithmic conformal field theories that are fairly well un...
Toward a Theory of International New ventures
Benjamin M. Oviatt; Patricia Phillips McDougall
1994-01-01
Organizations that are international from inception – international new ventures – form an increasingly important phenomenon that is incongruent with traditionally expected characteristics of multinational enterprises. A framework is presented that explains the phenomenon by integrating international business, entrepreneurship, and strategic management theory. That framework describes four necessary and sufficient elements for the existence of international new ventures: (1) organizational fo...
Wittgenstein's category of use as a starting point for the theory of language
Derra, Aleksandra
2010-01-01
The author concentrates on the methodological aspects of a theory of language in which one could explain all basic problems related to natural language, especially such as the phenomenon of meaning, language acquisition, knowledge of language, the relation between natural language and the language of thought etc. She believes we should develop Wittgensteinian approach where the category of use plays the central role in explaining meaning. We should also reject double aspect theories of meanin...

With a view to providing contextual background for the Special Issue, this opening article analyses several dimensions of ‘The end of International Relations theory?’ It opens with a consideration of the status of different types of theory. Thereafter, we look at the proliferation of theories...... to the alternatives currently being practised: integrative pluralism. The article ends on a cautiously optimistic note: given the disciplinary competition that now exists in relation to explaining and understanding global social forces, International Relations may find resilience because it has become theory...
Some proposals for the set-theoretic foundations of category theory
Lorenzo Malatesta
2011-01-01
The problem of finding proper set-theoretic foundations forcategory theory has challenged mathematician since the very beginning. In this paper we give an analysis of some of the standard approaches that havebeen proposed in the past 70 years. By means of the central notions of class and universe we suggest a possible conceptual recasting of these proposals. We focus on the intended semantics for the (problematic) notion of large category in each proposed foundation. Following Feferman (2006)...

It draws on the Theory of Clubs (Buchanan, 1965) and builds a model that aims to explain governments' optimal choices when joining international organizations. The results of the model show that governmental willingness to enlarge international organizations and to increase their degree of commitment are decreasing functions of both, the size of the organization, and the country's degree of com...
Some proposals for the set-theoretic foundations of category theory

2011-11-01
Full Text Available The problem of finding proper set-theoretic foundations forcategory theory has challenged mathematician since the very beginning. In this paper we give an analysis of some of the standard approaches that havebeen proposed in the past 70 years. By means of the central notions of class and universe we suggest a possible conceptual recasting of these proposals. We focus on the intended semantics for the (problematic notion of large category in each proposed foundation. Following Feferman (2006 we give a comparison and evaluation of their expressive power.
Pragmatism in International Relations Theory and Research.
Ralston, Shane J
2011-01-01
The goal of this paper is examine the recent literature on the intersection between philosophical pragmatism and International Relations (IR), including IR theory and IR research methodology. One of the obstacles to motivating pragmatist IR theories and research methodologies, I contend, is the difficulty of defining pragmatism, particularly whether there is a need for a more generic definition of pragmatism or one narrowly tailored to the goals of IR theorists and researchers. Even though ph...
Complexity theory, systems thinking and international relations
Bousquet, Antoine; Curtis, S
2011-01-01
The concepts, language and methods of complexity theory have been slowly making their way into international relations (IR), as scholars explore their potential for extending our understanding of the dynamics of international politics. In this article we examine the progress made so far and map the existing debates within IR that are liable to being significantly reconfigured by the conceptual resources of complexity. We consider the various ontological, epistemological and methodological que...

As it is known the labor law presents one of the fundamental rights of the human being, thus such rights (right to work, freedom of work are constitutional category and protected in whole legal systems of the present time. The efforts to install such positive spirit were not easy. Genuinely is known that bearers of progressive developments in this field (end of XIX century were organized groups of workers (unions, then initiatives from various statesmen and later to be materialized from the governments of present time followed by the addressing and protecting of these rights in international aspect. Practice has proved that creation, purpose and activity of International Labor Organization has provided its benefits in achieving the primary principles of work, such rights proclaimed by the majority of world states and embedded in their highest legal act (Constitution of the organization in question (ILO. We consider that bearers of government politics of Kosovo, responsible sectors of this field respectively, shall regard these rules set and implemented by this international body and at the same time make maximal efforts towards advancing the current legislation in this field as well as to utilize all necessary resources in order to achieve the vital goal which is the adherence in ILO. This would certainly have an impact on minimizing the occurrence of eventual discontent from the organized groups (Unions as well as other classes and naturally the progress and positive effects in this field would be visible and useful for the society.
5th International Conference on Operator Theory
Douglas, R; Nagy, B; Voiculescu, D; Arsene, Gr
1981-01-01
The first of the annual Operator Theory conferences in Ti mi~oara held four years ago was a meeting of operator theory spe cialists from the National Institute for Scientific and Techni cal Creation in Bucharest and from the University of Timi~oara. Since then, the participation to these conferences has greatly increased, by being attended first by operator theorists from allover the country and (since 1978) by an increasing number of foreign mathematicians. Thus the 1980 Conference can be regarded as a truly international Operator Theory meeting, fifteen coun tries being represented at it. These conferences are conceived as a means to promote the cooperation between specialists in all areas of Operator Theory. Among the main topics in 1980 were: dilation theory, invariant subspaces, connections with the theory of cX-algebras, subnormal operators, multidimensional functional calculus etc. Though not included in this volume, we would like to mention that in 1980 some special sessions concerning other f...

14th International Conference on Operator Theory
Timotin, D; Vasilescu, F-H
1993-01-01
Since 1976 the Institute of Mathematics of the Romanian Academy (formerly the Department of Mathematics of INCREST) and the Faculty of Mathematics (formerly the Faculty of Sciences) of the University ofTimi~oara have organized several Con ferences on Operator Theory. These Conferences were held yearly in Timi~oara (or in Timi~oara and Herculane) and beginning with 1985 they were held in Bucharest (1985,1986), in Timi~oara (1988) and in Predeal (1990). At the beginning, these Conferences answered the need of a part of the Romanian Mathematical Community ofexploring other forms of survival, after the dissolution of the Institute of Mathematics in 1975. Soon, these meetings evolved to International Conferences with a broad participation and where important results in Operator Theory and Operator Algebras and their interplay with Complex Function Theory, Differential Equations, Mathematical Physics, System Theory, etc. were presented. The 14th Conference on Operator Theory was held between June 1st and June 5th...

This paper begins with a brief description of the theoretical framework for prototype categorization,in which there lie two axes of words attributions,a vertical axis and a horizontal one.Verticaly,words differ in that we have the superordinate level categories,subordinate categories and the basic level categories.Horizontaly,we have the prototypes and the non-prototypes in reality.Elaborated with the varying data from neurolinguistics,this paper analyzes the reasons that drive nominal aphasias’ impairment in non-prototypes and non-basic level categories.Cognitive perception is the main drive,and besides,frequency of exposure,principle of economy and position in mental lexicon are also the causalities of the patients’ impairment in word recognition.

After giving a short description, in terms of action of categories, of some of the structures associated with sl(2) and sl(3) boundary conformal field theories on a torus, we provide tables of dimensions describing the semisimple and cosemisimple blocks of the corresponding weak bialgebras (quantum groupoids), tables of quantum dimensions and orders, and tables describing induction-restriction. For reasons of size, the sl(3) tables of induction are only given for theories with self-fusion (existence of a monoidal structure)

We develop a theory of enriched categories over a (higher) category M equipped with a class W of morphisms called homotopy equivalences. We call them Segal M_W -categories. Our motivation was to generalize the notion of "up-to-homotopy monoids" in a monoidal category M, introduced by Leinster. The formalism adopted generalizes the classical Segal categories and extends the theory of enriched category over a bicategory. In particular we have a linear version of Segal categories which did not exist so far. Our goal in this paper is to present the theory and provide some examples. Applications are reserved for the future.

We review some of our recent results (with collaborators) on information processing in an ordered linear spaces framework for probabilistic theories. These include demonstrations that many "inherently quantum" phenomena are in reality quite general characteristics of non-classical theories, quantum or otherwise. As an example, a set of states in such a theory is broadcastable if, and only if, it is contained in a simplex whose vertices are cloneable, and therefore distinguishable by a single measurement. As another example, information that can be obtained about a system in this framework without causing disturbance to the system state, must be inherently classical. We also review results on teleportation protocols in the framework, and the fact that any non-classical theory without entanglement allows exponentially secure bit commitment in this framework. Finally, we sketch some ways of formulating our framework in terms of categories, and in this light consider the relation of our work to that of Abramsky, ...
International Exchange: A Foundation for Theory Building in International Business

There does not appear to be consensus concerning what is the conceptual domain of international business. This paper argues that this is due in part to an emphasis on the firm as the unit of analysis. It is further argued that a comprehensive, generative and theoretically integrative definition of international business could be established if exchange were made the unit of analysis. By using the political economy paradigm and the various concepts of exchange adopted by the social sciences, n...

1986-01-01
The annual Operator Theory conferences, organized by the Department of Mathematics of INC REST and the University of Timi?oara, are intended to promote cooperation and exchange of information between specialists in all areas of operator theory. This volume consists of papers contributed by the participants of the 1984 Conference. They reflect a great variety of topics, dealt with by the modern operator theory, including very recent advances in the invariant subspace problem, subalgebras of operator algebras, hyponormal, Hankel and other special classes of operators, spectral decompositions, aspects of dilation theory and so on. The research contracts of the Department of Mathematics of INCREST with the National Council for Science and Technology of Romania provided the means for developing the research activity in mathematics; they represent the generous framework of these meetings, too. It is our pleasure to acknowledge the financial support of UNESCO which also contibuted to the success of this meeting. We ...
Introduction:Bourdieu and International Relations theory

This book rethinks the key concepts of International Relations by drawing on the work of Pierre Bourdieu.The last few years have seen a genuine wave of publications promoting sociology in international relations. Scholars have suggested that Bourdieu’s vocabulary can be applied to study security, diplomacy, migration and global environmental politics. Yet we still lack a systematic and accessible analysis of what Bourdieu-inspired IR might look like. This book provides the answer. It offers a...
Rethinking social identity theory in international encounters:

In a globalized business environment, interaction across linguistic boundaries is becoming a normal part of everyday life. In these encounters language differences may affect the formation of social identities among organization members. While studies based on Social Identity Theory perceive the...... link between identity and language to be linear, this article takes a different approach. By drawing on anthropological theories on ethnic identity it is argued that the relation between language and social identity is negotiated in interaction. In the empirical analysis the article focuses on the...

On the unity of International Law Theory
Directory of Open Access Journals (Sweden)
Pablo J. Martín Rodríguez
2011-01-01
Full Text Available It has become a truism that international lawyers are, nowadays, facing a sharp disagreement regarding the main methodological foundations of the discipline. The issue cannot be whether or not there is such a division in the IL school of thought, but which its specific features are. In the present paper, it is submitted here that the current situation is not due to the various methodologies at our disposal, but an actual paradigmatic schism with deep repercussions on the main research agenda. This paradigmatic split steers our attention to the incommensurability of the different paradigms at stake, and consequently the mere possibility of a meaningful communicative interaction between them is dismissed. This picture, though, may be not fully convincing. This multi-paradigmatic state and its ongoing reissue could be seen in a different way, once we accept that neither perfect communication ever obtains nor absolute lack of contradiction is such an epistemological premise. Then, the admittedly existing cross-references, links and overlaps between different approaches can be interpreted not as a paradigmatic mistake (a sort of an internally dysfunctional approach, but as an acknowledgement by each paradigm of its inability to fully explain International Law reality and its openness to alterity, i.e., a recognition of other paradigms as legitimate interlocutors. This interparadigmatic dialogue, that is also noticeable in the main debates on IL structure, shows the most appropriate direction for international lawyers to follow, even if a final paradigmatic converging horizon is not conceivable or even possible.

We describe a 2-dimensional analogue of track categories, called two-track categories, and show that it can be used to model categories enriched in 2-type mapping spaces. We also define a Baues-Wirsching type cohomology theory for track categories, and explain how it can be used to classify two-track extensions of a track category D by a module over D.

In this paper, the implicit and explicit conceptualizations of international organizations found in the three major theories of international relations are outlined and compared. It turns out that in a neorealist framework, international organizations can be explained; however, they exhibit no autonomy and cannot therefore be conceptualized as a corporate actor. Principally, the same applies to rational choice institutionalism, although limited autonomy is conceivable. Both theories are reduc...

The present volume consist of papers contributed by the partici pants of the 1981 Conference. Since many of these papers contain results on the invariant subspace problem or are related to the role of invariant subspaces in the study of operators or operator systems, we thought it appropiate to mention this in the title of the volume, though the "other topics" have a wide range. As in past years, special sessions concerning other fields of Functio nal Analysis were organized at the 1981 Conference, but contri butions to these sessions are not included in the present volume.

JET internal transport barriers: experiment vs theory
International Nuclear Information System (INIS)
A large variety of JET discharges with internal transport barriers (ITBs) has been analysed in order to determine the main features which characterize turbulence stabilization at the barrier. It is found that the location of barriers is well correlated with regions where the ExB flow shearing rate exceeds the linear growth rate of the ion temperature gradient mode instability (γηi). A key point is the dependence of γηi on the magnetic shear: in the discharges of this database the reduction of γηi associated to very low or null magnetic shear favours the formation of an ITB. After the ITB formation a positive feedback occurs in which the ExB flow shear mechanism has the leading role and the position of the barrier may be no longer linked to the low shear region

The „Collateral Estoppel” Theory in International Law
Directory of Open Access Journals (Sweden)
Claudia ANDRIŢOI
2011-08-01
Full Text Available The objectives of the article are represented by the fact that the interdependence of the two legal orders, internal and international, refers to the fact that, international law without internal law signifies federalization, which the contrary situation signifies the impossibility of establishing an international community. The rules of international law are applied to national court according to national constitutions and for domestic purposed. According to the theory of the act of state, even if it would seem that, at least internal acts of implementation of international rules are subjected to internal jurisdictions, the resolutions implemented often touch the problem of security and public order that escapes the judicial competencies. But, sometimes, the refuse of controlling the resolutions of the SC has been justified according to the UN Charta supremacy. In this case, national courts have been in the position of interpreting the CS resolutions. In conclusion it results that international law will efficiency the application of positive law being at least, an instrument of interpreting, and, on the other side, national law represents an exclusive means of transposing international regulation on a state plan.
Differentiation: a sociological approach to international relations theory
Barry BUZAN; Albert, Mathias
2010-01-01
This article sets out an analytical framework of differentiation derived from sociology and anthropology and argues that it can and should be applied to international relations (IR) theory. Differentiation is about how to distinguish and analyse the components that make up any social whole: are all the components essentially the same, or are they distinguishable by status or function? We argue that this approach provides a framing for IR theory that is more general and integrative than narrow...
Endowment Versus Finance; A Wooden Barrel Theory of International Trade

This paper develops a theory of international trade in which financial development and factor endowments jointly determine comparative advantage. We apply the financial contract model of Holmstrom and Tirole (1998) to the Heckscher-Ohlin-Samuelson (HOS) model in which firms' dependence on external finance is endogenous, and the demand for external finance is constrained by financial development. The theory nests HOS model as a special case. A key result that emerges is what we call the law of...
The Concept of Security in International Relations Theory
Directory of Open Access Journals (Sweden)
Gabriel Orozco
2006-01-01
Full Text Available The end of the Cold War and the emergence of globalisation have transformed the reality of International Relations, which has meant a change in the theories which this reality had assumed. The concept of security reveals itself as an organisational idea on the different phenomena of globalisation, carrying out a programme of research that goes beyond the realistic presumptions of military power or of the idealistic principles of research for peace. This article explores the new meanings of security for International Relations theory and discusses the theoretical models that influence policy design and that aim to confront the problems and challenges of security in globalisation.

International Trade and Net Investment: Theory and Evidence
Lucas Bretschger; Simone Valente
2011-01-01
The theory of welfare accounting shows that comprehensive measures of net investment can be used to test whether an economy is following unsustainable paths of consumption. However, the notion of net investment used in most applied studies rules out technological progress and terms-of-trade gains from international trade. This paper considers an augmented expression of net investment derived from a dynamic growth model featuring international trade in different types of resource inputs, exoge...

The rules promulgated by these institutions as the central pillars of global economic governance are both indeterminate and susceptible to external influences, leading to unpredictable outcomes in the longer ter...
Development theory and changes in the international system
Directory of Open Access Journals (Sweden)
José Antonio Alonso
2012-12-01
Full Text Available Development theory has undergone several changes over the last two decades. However, the international reality has changed more profoundly. The increased heterogeneity of the developing world, the diverse experience of economic success among some developing countries, the new geography of global poverty, the increased multipolarity of the international system and the wider spheres of international public assets are just some of these changes. Thus, it is necessary to think again about the development process and the strategies that are required to promote economic and social change. This article represents an attempt to contribute to that reflection.

MOTIVATION INTERNALIZATION AND SIMPLEX STRUCTURE IN SELF-DETERMINATION THEORY.
Ünlü, Ali; Dettweiler, Ulrich
2015-12-01
Self-determination theory, as proposed by Deci and Ryan, postulated different types of motivation regulation. As to the introjected and identified regulation of extrinsic motivation, their internalizations were described as "somewhat external" and "somewhat internal" and remained undetermined in the theory. This paper introduces a constrained regression analysis that allows these vaguely expressed motivations to be estimated in an "optimal" manner, in any given empirical context. The approach was even generalized and applied for simplex structure analysis in self-determination theory. The technique was exemplified with an empirical study comparing science teaching in a classical school class versus an expeditionary outdoor program. Based on a sample of 84 German pupils (43 girls, 41 boys, 10 to 12 years old), data were collected using the German version of the Academic Self-Regulation Questionnaire. The science-teaching format was seen to not influence the pupils' internalization of identified regulation. The internalization of introjected regulation differed and shifted more toward the external pole in the outdoor teaching format. The quantification approach supported the simplex structure of self-determination theory, whereas correlations may disconfirm the simplex structure. PMID:26595290
Democracy of internal symmetries in supersymmetrical quantum field theory
International Nuclear Information System (INIS)
The freedom of choice of some discrete and internal symmetries in the supersymmetric, massive, interacting quantum field theory is discussed. It is shown that the discrete symmetry consisting of changing the sign of some (not all) scalar fields is incompatible with the supersymmetric structure of the theory. It is further demonstrated that an internal symmetry which transforms only some of the fields of fixed spin leaving the other fields invariant and which acts nontrivially on the supercharges can not be admitted as a symmetry; although it can be a good internal symmetry in absence of supersymmetric covariance. Moreover, in case of a model consisting of scalar, spinor and vector fields even a symmetry which transforms all of the scalar (vector) fields leaving spinor and vector (scalar) fields unaffected is ruled out provided it acts nontrivially on some of the supercharges

Theories of International Relations and the Explanation of Foreign Aid
Directory of Open Access Journals (Sweden)
PAUSELLI, Gino
2013-06-01
Full Text Available 50 years after the publication of the first and influential article in international relations (IR analyzing foreign aid motivations, A theory of foreign aid, by Hans Morgenthau, IR scholarship has not yet accomplished a consistent theoretical body explaining international development cooperation. Most of the empirical studies on foreign aid have been contributions from other disciplines, especially economics. Research from the field of international relations has been mostly descriptive or poorly connected with IR paradigms.This article proposes to analyze motivations of foreign aid allocations decisions of donors. These motivations will be examined from the theoretical perspective of the international relations scholarship. In this way, it is sought to contribute, from the discipline of IR, to the explanation of the process in which developed countries make transfers of resources to developing countries.
At the limit: on realism, materialism and international theory
Davenport, Andrew
2012-01-01
Central to Realism’s framing of the international are its conception of the inside/outside structure of political form and the idea of a state of nature. This thesis provides a materialist critique of these conceptions. Its starting point is that the Marxist criticism of Realism has fallen short because Marxism in IR has constructed no theory of the political and as a result it has been unable to answer Realism’s perception of the ‘tragic’ and unchanging nature of international...

The paper will review the theoretical implications and empirical properties of the widely-used Armington specification,...
Beyond constructivism: expanding the boundaries of international relations theory
Nicole V.T. Lugosi
2012-01-01
One of the key research areas of Political Science is the field of International Relations (IR). Many scholars who speak of IR in terms of its Great Debates understand constructivism as the critical turn in theory. The main appeal of constructivism is the application of identity to IR problems. Interrogating the social construction of world order and considering identity as a factor enables scholars to offer better, deeper explanations. However, other scholars insist the constructivist turn i...

Global Opinion Theory and the English School of International Relations
Rusciano Frank L.
2010-01-01
It is generally accepted that the English School of international relations theory, associated with the London School of Economics, approaches its subject from a different perspective than its American variants. This perception has endured into the post-Cold War era. Despite their countries special relationship, the American and English approaches are assumed to be separated by a common language, opposing assumptions, and divergent global interests.The following article challenges this percep...

This paper presents Ramsey theory in category-theoretic terms as a message from a non-expert author to a non-expert reader. Everything is explained starting from the level zero, and an attempt is made to be as self-explanatory in the terminology and notation as possible. For the sake of references, the paper also reproduces traditional terminology, with concepts and theorems often named after (presumed) discoverers who are largely unknown to outsiders to the field. The sources are referred to in a manner so as to make them easy to find on the web; only exceptionally are non-freely accessible items referred to. Certain questions are formulated as 'conjectures', not out of a deep belief in their validity but because they sound better stated explicitly. There are no new results in this article, no deepening of particular aspects of Ramsey theory, no attempts to be comprehensive. But, in the spirit of the ideas of Anatoly Vershik, an attempt is made to move transversally across common directions of research, to see interrelations between them and to formulate questions. In fact, the article reproduces a chapter from the author's as yet unfinished manuscript "A number of questions". Bibliography: 65 titles.

The second volume of Condensed Matter Theories contains the proceedings of the 10th International Workshop held at Argonne National Laboratory, Argonne, IL, U.S.A. during the week of July 21, 1986. The workshop was attended by high-energy, nuclear and condensed-matter physicists as well as materials scientists. This diverse blend of participants was in keeping with the flavor of the previous workshops. This annual series of international workshops was"started in 1977 in Sao Paulo, Brazil. Subsequent'workshops were held in Trieste (Italy), Buenos Aires (Argentina), Caracas (Venezuela), Altenberg (West Germany), Granada (Spain), and San Francisco (U.S.A.). What began as a meeting of the physicists from the Western Hemisphere has expanded in the last three years into an international conference of scientists with diverse interests and backgrounds. This diversity has promoted a healthy exchange of ideas from different branches of physics and also fruitful interactions among the participants. The present volume is...

Many theories of category learning assume that learning is driven by a need to minimize classification error. When there is no classification error, therefore, learning of individual features should be negligible. We tested this hypothesis by conducting three category learning experiments adapted from an associative learning blocking paradigm. Contrary to an error-driven account of learning, participants learned a wide range of information when they learned about categories, and blocking effe...
International Summer School on Mathematical Systems Theory and Economics
Szegö, G
1969-01-01
The International Summer School on Mathematical Systems Theory and Economics was held at the Villa Monastero in Varenna, Italy, from June 1 through June 12, 1967. The objective of this Summer School was to review the state of the art and the prospects for the application of the mathematical theory of systems to the study and the solution of economic problems. Particular emphasis was given to the use of the mathematical theory of control for the solution of problems in economics. It was felt that the publication of a volume collecting most of the lectures given at the school would show the current status of the application of these methods. The papers are organized into four sections arranged into two volumes: basic theories and optimal control of economic systems which appear in the first volume, and special mathematical problems and special applications which are contained in the second volume. Within each section the papers follow in alphabetical order by author. The seven papers on basic theories are a rat...

Competition in electricity spot markets. Economic theory and international experience
Energy Technology Data Exchange (ETDEWEB)
Fehr, Nils-Henrik von der; Harbord, David
1998-09-01
This publication gives a survey of economic theory and international experience connected to electricity spot markets. The main purpose is to consider the attempts that have been made to apply economic theory and empirical methods to the analysis of electricity markets, and to evaluate them in light of theoretical considerations and empirical evidence. The publication describes in simple terms the basic pool pricing mechanism, and experience with pools in a number of countries. It is worth emphasizing that it is not the purpose to treat in extensive detail the structure of electricity pools around the world. Key factors of the markets in England and Wales, Norway and Australia are described in order to allow for a comparison of design issues and evaluation of competitive performance. 80 refs., 14 figs., 15 tabs.

8th International Conference on Hyperbolic Problems : Theory, Numerics, Applications
Warnecke, Gerald
2001-01-01
The Eighth International Conference on Hyperbolic Problems - Theory, Nu merics, Applications, was held in Magdeburg, Germany, from February 27 to March 3, 2000. It was attended by over 220 participants from many European countries as well as Brazil, Canada, China, Georgia, India, Israel, Japan, Taiwan, und the USA. There were 12 plenary lectures, 22 further invited talks, and around 150 con tributed talks in parallel sessions as well as posters. The speakers in the parallel sessions were invited to provide a poster in order to enhance the dissemination of information. Hyperbolic partial differential equations describe phenomena of material or wave transport in physics, biology and engineering, especially in the field of fluid mechanics. Despite considerable progress, the mathematical theory is still strug gling with fundamental open problems concerning systems of such equations in multiple space dimensions. For various applications the development of accurate and efficient numerical schemes for computat...

Reconstruction of boundary conditions from internal conditions using viability theory
Hofleitner, Aude
2012-06-01
This article presents a method for reconstructing downstream boundary conditions to a HamiltonJacobi partial differential equation for which initial and upstream boundary conditions are prescribed as piecewise affine functions and an internal condition is prescribed as an affine function. Based on viability theory, we reconstruct the downstream boundary condition such that the solution of the Hamilton-Jacobi equation with the prescribed initial and upstream conditions and reconstructed downstream boundary condition satisfies the internal value condition. This work has important applications for estimation in flow networks with unknown capacity reductions. It is applied to urban traffic, to reconstruct signal timings and temporary capacity reductions at intersections, using Lagrangian sensing such as GPS devices onboard vehicles.

International Nuclear Information System (INIS)
The International Centre for Theoretical Physics has maintained an interdisciplinary character in its research and training program so far as different branches of theoretical physics are concerned. In pursuance of this aim the Centre has organized extended research courses with a comprehensive and synoptic coverage in varying disciplines. The first of these — on Plasma Physics — was held in 1964; the second in 1965 was concerned with the physics of particles; the third in 1966 covered nuclear theory; the fourth in 1967 dealt with condensed matter. The proceedings of all these courses were published by the International Atomic Energy Agency. The present volume records the proceedings of the fifth course, held from 7 January to 31 March 1969, which was concerned with the study of microscopic nuclear structure and the many-body approaches to nuclear theory

Relationalism or why diplomats find international relations theory strange

In this conclusion, which reflects critically on the relational approach to diplomacy and its wider consequences, I argue that diplomats are estranged from IR theory and vice versa - because International Relations scholars generally subscribe to substantialism, whereas diplomats tend to think...... in terms of relations. In fact, a deeper understanding of these relations is a key theoretical take-away point of this book. More specifically, I argue that relationalism - as a meta-theoretical approach - not only helps us understand the diplomatic production of world politics, relationalism also reflects...... unarticulated sense, that world politics is deeply relational. Their job is to make those relations "work," and they are convinced that important knowledge can be gained by consulting and meeting with foreign powers, that is, "the other." As such, they subscribe to a relational thinking (shared to some extent...

1988-01-01
This book is the third volume in an approximately annual series which comprises the proceedings of the International Workshops on Condensed Matter Theories. The first of these meetings took place in 1977 in Sao Paulo, Brazil, and successive workshops have been held in Trieste, Italy (1978), Buenos Aires, Argentina (1979), Caracas, Venezuela (1980), Mexico City, Mexico (1981), St. Louis, USA (1982), Altenberg, Federal Republic of Germany (1983), Granada, Spain (1984), San Francisco, USA (1985), and Argonne, USA (1986). The present volume contains the proceedings of the Eleventh Workshop which took place in Qulu, Finland during the period 27 July - 1 August, 1987. The original motivation and the historical evolution of the series of Workshops have been amply described in the preface to the first volume in the present series. An important objective throughout has been to work against the ever-present trend for physics to fragment into increasingly narrow fields of specialisation, between which communication is d...

In this paper I develop a non-structuralist interpretation of categorical mathematics and show its consequences for history...

The first two chapters of this book offer a modern, self-contained exposition of the elementary theory of triangulated categories and their quotients. The simple, elegant presentation of these known results makes these chapters eminently suitable as a text for graduate students. The remainder of the book is devoted to new research, providing, among other material, some remarkable improvements on Brown''s classical representability theorem. In addition, the author introduces a class of triangulated categories""--the ""well generated triangulated categories""--and studies their properties. This

A Convenient Category of Domains
Battenfeld, Ingo; Schröder, Matthias; Simpson, Alexander
2007-01-01
We motivate and define a category of topological domains, whose objects are certain topological spaces, generalising the usual ω-continuous dcppos of domain theory. Our category supports all the standard constructions of domain theory, including the solution of recursive domain equations. It also supports the construction of free algebras for (in)equational theories, can be used as the basis for a theory of computability, and provides a model of parametric polymorphism.

Using categorical techniques we obtain some results on localization and colocalization theory in Grothendieck categories with a set of small projective generators. In particular,we give a sufficient condition for such category to be semiartinian. For semiartinian Grothendieck categories where every simple object has a projective cover,we obtain that every localizing subcategory is a TTF-class. In addition,some applications to semiperfect categories are obtained.

Quantization problems suggest that the category of symplectic manifolds and symplectomorphisms be augmented by the inclusion of canonical relations as morphisms. These relations compose well when a transversality condition is satisfied, but the failure of the most general compositions to be smooth manifolds means that the canonical relations do not comprise the morphisms of a category. We discuss several existing and potential remedies to the nontransversality problem. Some of these involve restriction to classes of lagrangian submanifolds for which the transversality property automatically holds. Others involve allowing lagrangian "objects" more general than submanifolds.

Full Text Available It is argued that both the traditional clerical paradigm of an ecclesial approach and the phenomenological paradigm of an empirical approach are not sufficient enough to describe and maintain a theological methodology in practical theology. This has led to the introduction of a theopaschitic paradigm in theory formation. It is argued that the normative task of practical theology implies a philosophical-hermeneutical dimension, that is, to interpret under girding paradigms as related to meaning and being. It also implies a theological dimension; to reflect theologically on the praxis of God as an influential factor within human actions (inhabitational theology. With reference to ‘the pneumatological praxis of God’, a practical theology of the intestines is proposed. Bowel categories reveal a divine intentionality (teleology and describe a modus of God’s praxis, the how of God within the vulnerability and suffering of human beings. This divine ontological mode should operate as a practical theological paradigm determining being qualities (ontic status within human actions and processes of communication. The under girding theological presupposition is that ta splanchna [strong feeling of mercy and compassion expressed by the intestines] denotes a compassionate praxis of co-suffering (the passio Dei. Passion in practical theology emanates in parrhesia and instills a vivid hope: fides quaerens spem [faith in search of hope].
Hyperfine coupling constants from internally contracted multireference perturbation theory
Shiozaki, Toru
2016-01-01
We present an accurate method for calculating hyperfine coupling constants (HFCCs) based on the complete active space second-order perturbation theory (CASPT2) with full internal contraction. The HFCCs are computed as a first-order property using the relaxed CASPT2 spin-density matrix that takes into account orbital and configurational relaxation due to dynamical electron correlation. The first-order unrelaxed spin-density matrix is calculated from one- and two-body spin-free counterparts that are readily available in the CASPT2 nuclear gradient program [M. K. MacLeod and T. Shiozaki, J. Chem. Phys. 142, 051103 (2015)], whereas the second-order part is computed directly using the newly extended automatic code generator. The relaxation contribution is then calculated from the so-called Z-vectors that are available in the CASPT2 nuclear gradient program. Numerical results are presented for the CN and AlO radicals, for which the CASPT2 values are comparable (or, even superior in some cases) to the ones computed ...

2008-09-01
A compilation of the available experimental internal conversion coefficients (ICCs), αT, αK, αL, and ratios K/L and K/LM of high multipole ( L > 2) transitions for a number of elements in the range 21 ⩽ Z ⩽ 94 is presented. Our listing of experimental data includes 194 data sets on 110 E3 transitions, 10 data sets on 6 E4 transitions, 11 data sets on 7 E5 transitions, 38 data sets on 21 M3 transitions, and 132 data sets on 68 M4 transitions. Data with less than 10% experimental uncertainty have been selected for comparison with the theoretical values of Hager and Seltzer [R.S. Hager, E.C. Seltzer, Nucl. Data Tables A 4 (1968) 1], Rosel et al. [F. Rösel, H.M. Fries, K. Alder, H.C. Pauli, At. Data Nucl. Data Tables 21 (1978) 91], and BRICC. The relative percentage deviations (%Δ) have been calculated for each of the above theories and the averages (%Δ¯) are estimated. The Band et al. [I.M. Band, M.B. Trzhaskovskaya, C.W. Nestor Jr., P.O. Tikkanen, S. Raman, At. Data Nucl. Data Tables 81 (2002) 1] tables, using the BRICC interpolation code, are seen to give theoretical ICCs closest to experimental values.

International Nuclear Information System (INIS)
The International Centre for Theoretical Physics, since its inception, has striven to maintain an interdisciplinary character in its research and training programme as far as different branches of theoretical physics are concerned. in pursuance of this aim the Centre has followed a policy of organizing extended research seminars with a comprehensive and synoptic coverage on varying disciplines. The first of these — lasting over a month — was held in 1964 on fluids of ionized particles and plasma physics; the second, lasting for two months, was concerned with physics of elementary particles and high-energy physics; the third, of three months’ duration, October — December 1966, covered nuclear theory; the fourth, bringing the series through a complete cycle, was a course on condensed matter held from 3 October to 16 December 1967. The present volume records the proceedings of this research seminar. The publication is divided into four parts containing 29 papers. Part I — General Courses, Part II - Dynamical lattice properties; Part III — Liquids and molecules; Part IV — Electronic properties

Lattice 2012, the 30th International Symposium on Lattice Field Theory was held in Cairns, Australia from Sunday the 24th of June to Friday the 29th June 2012. It was held at the Cairns Convention Centre, providing world-class facilities in a beautiful location. Fine weather and easy access to world heritage attractions including the Great Barrier Reef and the Wet Tropics Rainforests made for an extraordinary experience. The conference was organised by the Special Research Centre for the Subatomic Structure of Matter (CSSM) in the School of Chemistry & Physics at the University of Adelaide. More than 285 participants from around the world attended the symposium. The scientific program contained 22 plenary talks and 248 parallel contributions including posters. Most of these are recorded in this proceedings. For 30 years, the Lattice meeting has provided researchers from around the world with an annual forum at which to disseminate and discuss ideas, developments and opportunities in the study of relativistic quantum fields regulated on a spacetime lattice. It fosters the exchange of ideas, networking, and builds relationships between researchers that are essential in facilitating rapid progress and the creation of new knowledge. The program included plenary talks, parallel talks and poster presentations on Algorithms and machines, Applications beyond QCD, Chiral symmetry, Hadron spectroscopy and interactions, Hadron structure, Nonzero temperature and density, Standard model parameters and renormalization, Theoretical developments, Vacuum structure and confinement and Weak decays and matrix elements. The International Advisory Committee provided excellent guidance in planning the scientific program of the conference and we thank the Committee for their important contributions. Thanks also to our presenters for the time and effort they put into preparing their talks and their proceedings. Many thanks to our Conference Secretariat, Sharon Johnson, Silvana Santucci

Full Text Available To define structural and functional changes of skin in women of different age groups with an additional internal pathology in this work intraoperative biopsy material of skin of 105 women at the age from 20 to 75 years, that was taken during standard surgery instrumentations for different defects of face skin correction, was investigated. Skin material of cheek face region was morphologically processed. To define parameters of microvessels, serial sections was investigated with the help of morphometry. It was determined, that involution dynamic of microvessel condition in papillary layer of derma coincides with grade reduction of relative volume of microvessels bed. There is growth of relative microvessels volume in reticular layer of derma in women of older age groups. Microcirculation age changes include structural disorders of intrapapillary capillary loops, disorganization of arterioles in papillary and reticular layers of derma, disorders of venules because of the changes in microenvironmental fibrillar network. It is typical at the patients with nicotinic dependence, ischemic heart disease, hypertonic disease, a diabetes, and also adiposity of a different degree essential infringement of microvessels bed structure of a skin that gives the basis for allocation of the given contingent of patients as group high intraoperative and postoperative risk at carrying out of operative interventions for correction of face skin involutive changes.
Research on adsorption mechanism of wall climbing robots based on internally balanced theory
Institute of Scientific and Technical Information of China (English)
FAN Ji-zhuang; ZHU Yan-he; ZHAO Jie; CAI He-gao
2007-01-01
The internally balanced theory proposed by the Japanese researchers, solved the contradiction between adsorption ability and moving capability of the permanent magnetic adsorption mechanism. However, it still has some problems when applied to wall climbing robots. This paper analyzes and improves this theory, and the improved internally balanced theory satisfies the requirements of the adsorption mechanism significantly. Finally, a practical prototype is proposed based on this method, and both the analysis using ANSYS and the experiment results justify the design validity.

In this paper we give a new foundational categorical formulation for operations and relations and objects parameterizing them. This generalizes operads and all their cousins including but not limited to PROPs, modular operads, twisted (modular) operads as well as algebras over operads and an abundance of other related structures, such as FI--algebras. The usefulness of this approach is that it allows us to handle all the classical as well as more esoteric structures under a common framework and we can treat all the situations simultaneously. Many of the known constructions simply become Kan extensions. In this common framework, we also derive universal operations, such as those underlying Deligne's conjecture, construct Hopf algebras as well as perform resolutions, (co)bar transforms and Feynman transforms which are related to master equations. For these applications, we construct the relevant model category structures.

A new interpretation of internal-variable theory in finite thermo-viscoelasticity
Huang, ZhuPing; Dui, GuanSuo; Yang, ShengYou
2013-03-01
Based on the non-equilibrium thermodynamics, an internal- variable theory in thermo-viscoelasticity at finite deformation was proposed by Huang in 1999. In this theory, a modified stretch of the molecular chain was introduced, and hence the molecular network model in rubber elasticity was extended to take into account the viscous and thermal effects of the material. The viscous dissipation of the material can then be described by means of these internal variables, which appear in the expression of the modified stretch. In order to give a clearer explanation on the physical implication of the internal variables, a connection between the internal-variable theory and theoretical formulation based on the multiplicative decomposition of the deformation gradient in existing literature is presented in this paper, which allows the above internal-variable theory to be more systematic.

A problem of finding the linear theory satisfaction limits in propagation of the internal gravity waves is considered. It is evident that internal gravity waves excitation, propagation in actual practice is highly nonlinear phenomenon. However with some reasonable assumptions it is possible to linearize equations of internal waves generation and propagation. It is shown that in interesting for us wavelength range we can use linear approximation during study of internal gravity waves dynamics....

Theory and practice of internalization of external costs
International Nuclear Information System (INIS)
External costs are those parts of total costs which bypass the market. To internalize them means to confront economic agents with the true costs and benefits of their economic activities. The concept of internalization does not really meet the requirements of preserving ecological equilibrium. Defining ecological constraints fits the needs much better. Implicit in ecological constraints are shadow prices. To let them emerge, markets for tradable emission permits would be appropriate. Carbon dioxide is used as an example. (author) 7 refs
Integrating integration theory: neo-functionalism and international regimes
Gehring, Thomas
1996-01-01
"It is common to juxtapose inter-governmentalism and neo-functionalism as the two most important, and seemingly mutually exclusive, frameworks to interpret the phenomenon of 'European integration' and its institutional dimension, the European Community. Inter-governmentalism promises to offer a broadly applicable concept for the analysis of international cooperative institutions. It recognises that the Community emerged from the self-help based international system and emphasis...

Full Text Available The paper presents a modern theory of emotional development - the Holodynski and Friedlmeyer's theory, as well as the criticism pointed at this theory. The author presents the key tenets of the theory: that emotional expressions of an infant are nonfocused, that the caregiver interprets and mirrors infant expressions, that an infant then imitates the expressions mirrored in such a way, that before speech occurs the expressions are transformed into signs, that those signs become internalized around the age of six, that auto-regulation later originates from social regulation of emotions. The author points out to similarities of this theory to the L. S. Vygotsky's theory of cognitive development. The critical commentary of the theory focuses on some of its shortcomings. First, the theory does not offer sufficient evidence in favor of the claim about the internalization of expressive signs. Second, some research findings contradict the assumption of caregiver's mirroring of infant's emotional expressions. Third, the internalization assumption implies that the (internalized sign does not only refer to, but even creates emotional feelings. Finally, the paper points out the various inconsistencies present in Holodynski and Friedlmeyer's text. The advantageous aspects of this theory are reflected in encompassing the whole life span and carrying important educational implications.

Possessive individualism and the domestic liberal roots of international political theory
Storms, Daniel Stuart
2004-01-01
Criticisms of realism and liberalism, traditionally the two dominant perspectives within international relations (IR) and international political economy (IPE) theory, have been widespread for the past two decades. What unites these critical theorists is their claim that IWIPE theory is both ahistorical and decontextualised. What is missing from this critical account is a sustained historical examination of liberal ontology at the domestic level and how it relates to current mainstream IRIIPE...
Categories for the working mathematician
MacLane, Saunders
1971-01-01
Category Theory has developed rapidly. This book aims to present those ideas and methods which can now be effectively used by Mathe maticians working in a variety of other fields of Mathematical research. This occurs at several levels. On the first level, categories provide a convenient conceptual language, based on the notions of category, functor, natural transformation, contravariance, and functor category. These notions are presented, with appropriate examples, in Chapters I and II. Next comes the fundamental idea of an adjoint pair of functors. This appears in many substantially equivalent forms: That of universal construction, that of direct and inverse limit, and that of pairs offunctors with a natural isomorphism between corresponding sets of arrows. All these forms, with their interrelations, are examined in Chapters III to V. The slogan is "Adjoint functors arise everywhere". Alternatively, the fundamental notion of category theory is that of a monoid -a set with a binary operation of multiplicati...

Field theory of the spinning electron: I - Internal motions
International Nuclear Information System (INIS)
One of the most satisfactory picture of spinning particles is the Barut-Zanghi (BZ) classical theory for the relativistic electron, that relates the electron spin with the so-called Zitterbewegung (zbw). The BZ theory has been recently studied in the Lagrangian and Hamiltonian symplectic formulations, both in flat and in curved space-time. The BZ motion equations constituted the starting point for two recent works about spin and electron structure, co-authored by us, which adopted the Clifford algebra formalism. In this letter, by employing on the contrary the ordinary tensorial language, we first write down a meaningful (real) equation of motion, describing particle classical paths, quite different from the corresponding (complex) equation of the standard Dirac theory. As a consequence, we succeed in regarding the electron as an extended-type object with a classically intelligible structure (thus overcoming some long-standing, well-known problems). Second, we make explicit the kinematical properties of the 4-velocity field vμ, which also result to be quite different from the ordinary ones, valid for scalar particles. At last, we analyze the inner zbw motions, both time-like and light-like, as functions of the initial conditions (in particular, for the case of classical uniform motions, the z component of spin s is shown to be quantized). In so doing, we make explicit the strict correlation existing between electron polarization and zbw kinematics. (author). 9 refs

We apply the Dwyer-Kan theory of homotopy function complexes in model categories to the study of mapping spaces in quasi-categories. Using this, together with our work on rigidification from [DS1], we give a streamlined proof of the Quillen equivalence between quasi-categories and simplicial categories. Some useful material about relative mapping spaces in quasi-categories is developed along the way.

The paper analyses kinematics and dynamics of internal rotations with spin and their effects on the constitutive relations for uniaxial (nematic) liquids and for weakly elastic nematic solids. It is shown that neglecting the internal rotational inertia terms and effects of director gradient made the stress symmetric. This not only highly simplifies the theories but also allows calculating all the kinematic variables of internal rotations without any additional constants, other than those pres...

Quotients of cluster categories
Jorgensen, Peter
2007-01-01
Higher cluster categories were recently introduced as a generalization of cluster categories. This paper shows that in Dynkin types A and D, half of all higher cluster categories are actually just quotients of cluster categories. The other half can be obtained as quotients of 2-cluster categories, the "lowest" type of higher cluster categories. Hence, in Dynkin types A and D, all higher cluster phenomena are implicit in cluster categories and 2-cluster categories. In contrast, the same is not...

Fibred type-theoretic fibration categories give categorical foundation of logical relation for identity types.
Subject categories and scope descriptions
International Nuclear Information System (INIS)
This document is one in a series of publications known as the ETDE/INIS Joint Reference Series. It defines the subject categories and provides the scope descriptions to be used for categorization of the nuclear literature for the preparation of INIS and ETDE input by national and regional centres. Together with the other volumes of the INIS Reference Series it defines the rules, standards and practices and provides the authorities to be used in the International Nuclear Information System and ETDE. A complete list of the volumes published in the INIS Reference Series may be found on the inside front cover of this publication. This INIS/ETDE Reference Series document is intended to serve two purposes: to define the subject scope of the International Nuclear Information System (INIS) and the Energy Technology Data Exchange (ETDE) and to define the subject classification scheme of INIS and ETDE. It is thus the guide to the inputting centres in determining which items of literature should be reported, and in determining where the full bibliographic entry and abstract of each item should be included in INIS or ETDE database. Each category is identified by a category code consisting of three alphanumeric characters. A scope description is given for each subject category. The scope of INIS is the sum of the scopes of all the categories. With most categories cross references are provided to other categories where appropriate. Cross references should be of assistance in finding the appropriate category; in fact, by indicating topics that are excluded from the category in question, the cross references help to clarify and define the scope of the category to which they are appended. A Subject Index is included as an aid to subject classifiers, but it is only an aid and not a means for subject classification. It facilitates the use of this document, but is no substitute for the description of the scope of the subject categories
Proceedings of the Kyoto international symposium : the jubilee of the meson theory
International Nuclear Information System (INIS)
Kyoto international symposium: The Jubilee of the Meson Theory was held at Kyoto International Conference Hall from August 15 to 17, 1985, under the auspices of the Research Institute for Fundamental Physics, the Faculty of Science and the College of Liberal Arts of Kyoto University, in cooperation with many organizations concerned. Meson theory was proposed by Hideki Yukawa in 1935, only a decade after the birth of quantum mechanics. At that time, much confusion prevailed about the applicability of quantum theory. Yukawa's meson theory indicated the right direction for developing particle physics, and established that quantum field theory is the correct theory even inside a nucleus. Thus it may be said that particle physics began with Yukawa's meson theory. The purpose of this symposium was to celebrate the 50th anniversary of Yukawa's meson theory, to review the development of particle physics during these 50 years and the application of meson physics to various fields, and to discuss current topics in particle physics in order to obtain some insight into its future progress in the fundamental theory of space-time and matter. 88 foreign physicists from 18 countries and 172 Japanese scientists participated, and 32 interesting talks were given.

The theory of belief functions, also known as evidence theory or Dempster-Shafer theory, was first introduced by Arthur P. Dempster in the context of statistical inference, and was later developed by Glenn Shafer as a general framework for modeling epistemic uncertainty. These early contributions have been the starting points of many important developments, including the Transferable Belief Model and the Theory of Hints. The theory of belief functions is now well established as a general framework for reasoning with uncertainty, and has well understood connections to other frameworks such as probability, possibility and imprecise probability theories. This volume contains the proceedings of the 2nd International Conference on Belief Functions that was held in Compiègne, France on 9-11 May 2012. It gathers 51 contributions describing recent developments both on theoretical issues (including approximation methods, combination rules, continuous belief functions, graphical models and independence concepts) an...
Some recent developments in the endochronic theory of plasticity - the concept of internal barriers
International Nuclear Information System (INIS)
In this paper the author introduces to the field of irreversible thermodynamics the concept of internal barriers. The concept is usually associated with physical events at the atomic level. The introduction of barriers at the phenomenological level lends another element of commonality between internal variables and molecular processes. Application to plasticity shows rewarding results, in terms of a realistic analytical representation of the mechanical response of metals to repeated loading-unloading histories. These results have been accomplished by assigning to each internal variable an intrinsic time scale which is exclusively defined in terms of the changes of the internal variable alone. Thus each internal variable is 'autonomous'. The author has named this version of the endochronic theory AUTOCHRONIC. It is shown that yield can be encompassed by the endochronic theory, in a fashion which is more akin, yet basically and fundamentally different, to Mroz's concept of multiple yield surfaces, whose mode of motion must be specified. Moreover, a single yield event is replaced by a sequence of yield events, where such a sequence may be made continuous, in a limiting sense, if so desired. In this paper the analytical representation of successive yielding events is accomplished by the introduction of the concept of INTERNAL BARRIERS. These ensure that an internal variable qsub(r) will not become activated until a barrier of magnitude μ has been overcome. The resulting theory is shown to describe with remarkable accuracy loading, unloading and cross behaviour of common metals. (Auth.)
Rigidification of quasi-categories
Dugger, Daniel
2009-01-01
We give a new construction for rigidifying a quasi-category into a simplicial category, and prove that it is weakly equivalent to the rigidification given by Lurie. Our construction comes from the use of necklaces, which are simplicial sets obtained by stringing simplices together. As an application of these methods, we use our model to reprove some basic facts from Lurie's "Higher Topos Theory" regarding the rigidification process.

It is hypothesized that gender and national identity have a significant effect on selective exposure to entertainment series when being salient. Two international quasi-experimental studies have been condu...
Approximation in quantale-enriched categories
Hofmann, Dirk
2010-01-01
Our work is a fundamental study of the notion of approximation in V-categories and in (U,V)-categories, for a quantale V and the ultrafilter monad U. We introduce auxiliary, approximating and Scott-continuous distributors, the way-below distributor, and continuity of V- and (U,V)-categories. We fully characterize continuous V-categories (resp. (U,V)-categories) among all cocomplete V-categories (resp. (U,V)-categories) in the same ways as continuous domains are characterized among all dcpos. By varying the choice of the quantale V and the notion of ideals, and by further allowing the ultrafilter monad to act on the quantale, we obtain a flexible theory of continuity that applies to partial orders and to metric and topological spaces. We demonstrate on examples that our theory unifies some major approaches to quantitative domain theory.
Coarse categories I: foundations
Luu, Viêt-Trung
2007-01-01
Following Roe and others (see, e.g., [MR1451755]), we (re)develop coarse geometry from the foundations, taking a categorical point of view. In this paper, we concentrate on the discrete case in which topology plays no role. Our theory is particularly suited to the development of the Roe (C*-)algebras C*(X) and their K-theory on the analytic side; we also hope that it will be of use in the strictly geometric/algebraic setting of controlled topology and algebra. We leave these topics to future papers. Crucial to our approach are nonunital coarse spaces, for which we introduce locally proper maps. Our coarse category Crs generalizes the usual one: its objects are nonunital coarse spaces and its morphisms (locally proper) coarse maps modulo closeness. Crs is much richer than the usual unital coarse category. As such, it has all nonzero limits and all colimits. We examine various other categorical issues. E.g., Crs does not have a terminal object, so we substitute a termination functor which will be important in t...
Abelian crossed modules and strict Picard categories
Quang, Nguyen Tien; Phung, Che Thi Kim; Tung, Ngo Sy
2013-01-01
In this paper, we state the notion of morphisms in the category of abelian crossed modules and prove that this category is equivalent to the category of strict Picard categories and regular symmetric monoidal functors. The theory of obstructions for symmetric monoidal functors and symmetric cohomology groups are applied to show a treatment of the group extension problem of the type of an abelian crossed module.
Compact generators in categories of matrix factorizations
Dyckerhoff, Tobias
2009-01-01
We study the category of matrix factorizations associated to the germ of an isolated hypersurface singularity. This category is shown to admit a compact generator which is given by the stabilization of the residue field. We deduce a quasi-equivalence between the category of matrix factorizations and the differential graded (dg) derived category of an explicitly computable dg algebra. Building on this result, we employ a variant of Toën's derived Morita theory to identify continuous functors b...
Dynamical analysis of mesoscale eddy-induced ocean internal waves using linear theories

This study aims to explore generation mechanisms of the ocean internal wave using the dynamical analysis methods based on linear theories. Historical cruise measurements and recent synthetic aperture radar (SAR) observations of mesoscale eddies with diame-ter of several tens of kilometers to hundreds of kilometers show that the internal wave packets with wavelength of hundreds of me-ters to kilometer exist inside the mesoscale eddies. This coexistence phenomenon and inherent links between the two different scale processes are revealed in the solutions of governing equations and boundary conditions for the internal wave disturbance with a horizontally slowly variable amplitude in a cylindrical coordinate system. The theoretical solutions indicate that the instability of eddy current field provides the dynamical mechanism to internal wave generation. The derived dispersion relation indicates that the internal wave propagation is modified by the eddy current field structure. The energy equation of the internal waves clearly shows the internal wave energy increment comes from the eddy. The theoretical models are used to explain the observation of the mesoscale ed-dy-induced internal waves off the Norwegian coast. The two-dimensional waveform solution of the anticyclonic eddy-induced internal wave packet appears as ring-shaped curves, which contains the typical features of eddy stream lines. The comparison of theoretical solutions to the structure of the internal wave packets on SAR image shows a good agreement on the major features.

Learnability theory is an attempt to illuminate the concept of learnability using a mathematical model of learning. Two models of learning of categorial grammars are examined here: the standard model, in which sentences presented to the learner are flat strings of words, and one in which sentences are presented in the form of functor-argument…

Internally contracted multireference coupled-cluster theory in a multistate framework
Aoto, Yuri Alexandre; Köhn, Andreas
2016-02-01
The internally contracted multireference coupled cluster (icMRCC) theory is reexamined in a multistate framework. The new derivation starts from the Bloch equations employing a wave operator similar to the one originally employed by Jeziorski and Monkhorst [Phys. Rev. A 24, 1668 (1981)], but allows for a multideterminantal model-space basis. The resulting working equations are a generalization of state-universal multireference coupled-cluster (SU-MRCC) theory. In the case of truncated cluster operators, energies and wave functions depend on the choice of the model-space basis. It is shown that the state-specific solutions of the original icMRCC theory exactly diagonalize the effective Hamiltonian of the multistate theory and thus decouple the multistate equations. While this in principle means that icMRCC is a multistate theory, we find that truncated icMRCC theory still shows minor artifacts close to avoided crossings, which can be removed by considering a true multistate ansatz. The results also shed new light on the orbital variance of the original SU-MRCC theory.

The concept of category from mathematics happens to be useful to computer programmers in many ways. Unfortunately, all "good" explanations of categories so far have been designed by mathematicians, or at least theoreticians with a strong background in mathematics, and this makes categories especially inscrutable to external audiences. More specifically, the common explanatory route to approach categories is usually: "here is a formal specification of what a category is; then look at these kno...
Transnational theories of order and change: heterodoxy in international relations scholarship
Palan, Ronen
2007-01-01
In this article I argue that the very meaning of ‘inter-national relations’ is emerging as a focus of debate in International Relations, particularly among the critical traditions in the discipline. No longer seen as a mere study of peace and war, IR is viewed as a component of general pan-disciplinary theories or order and change. The international sphere is perceived, accordingly, no longer as a system in its own right, but rather as a gigantic transmission belt, and a huge communication de...

An unorthodox unified theory is developed to describe external and internal attributes and symmetries of fundamental fermions, quarks and leptons. Basic ingredients of the theory are an algebra which consists of all the triple-direct-products of Dirac {gamma}-matrices and a triple-spinor-field, called a triplet field, defined on the algebra. The algebra possesses three commutative subalgebras which describe, respectively, the external spacetime symmetry, the family structure and the internal color symmetry of quarks and leptons. The triplet field includes threefold (fourfold) repetitional modes of spin 1/2 component fields with SU(3) (SU(4)) color symmetry. It is possible to qualify the Yukawa interaction and to make a new interpretation of its coupling constants naturally in an intrinsic mechanism of the triplet field formalism. The Dirac mass matrices with quasi-democratic structure are derived as an illustration.

The International Centre for Theoretical Physics has maintained an interdisciplinary character in its research and training program so far as different branches of theoretical physics are concerned. In pursuance of this aim the Centre has organized extended research courses with a comprehensive and synoptic coverage in varying disciplines. The first of these - on Plasma Physics — was held in 1964; the second, in 1965, was concerned with the physics of particles; the third, in 1966, covered nuclear theory; the fourth, in 1967, dealt with condensed matter; the fifth, in 1969, was a course on nuclear structure. The proceedings of all these courses were published by the International Atomic Energy Agency. The present volume records the proceedings of the sixth course, held from 12 January to 10 April 1970, which was concerned with the study of the theory of imperfect crystalline solids

One of the cornerstones of the modern welfare approach to international trade theory is the compensation principle due to Samuelson. The difficulty with the compensation principle is that it pays scant attention to the way in which the equilibrium of the system changes when compensation is actually paid. This paper is concerned with the efficient location of the set of the utility-compensated equilibria; that is, the set of equilibria that satisfies the condition that compensation be paid suc...
Home-Biased Demand and International Specialisation: A Test of Trade Theories
Marius BRÜLHART; Federico TRIONFETTI
2000-01-01
We develop and apply a discriminating criterion to distinguish the two principal paradigms of international trade theory: constant-returns perfectly competitive models on the one hand, and increasing-returns monopolistically competitive models on the other. Our criterion rests on the existence of home-biased demand. It predicts a positive relationship between countries' relative output and their relative home bias in increasing-returns sectors, and no relationship in constant-returns sectors....

Equality in Global Commerce: Towards a Political Theory of International Economic Law

Notwithstanding International Economic Law’s (IEL’s) inevitable distributional effects, IEL scholarship has had limited engagement with theoretical work on global distributive justice and fairness. In part this reflects the failure of global justice theorists to derive principles that can be readily applied to the concrete problems of IEL. This article bridges this gap, drawing on existing coercion-based accounts of global justice in political theory to propose a novel account of global distr...

International Workshop on Electronic Density Functional Theory : Recent Progress and New Directions
Vignale, Giovanni; Das, Mukunda
1998-01-01
This book is an outcome of the International Workshop on Electronic Density Functional Theory, held at Griffith University in Brisbane, Australia, in July 1996. Density functional theory, standing as it does at the boundary between the disciplines of physics, chemistry, and materials science, is a great mixer. Invited experts from North America, Europe, and Australia mingled with students from several disciplines, rapidly taking up the informal style for which Australia is famous. A list of participants is given at the end of the book. Density functional theory (DFT) is a subtle approach to the very difficult problem of predicting the behavior of many interacting particles. A major application is the study of many-electron systems. This was the workshop theme, embracing inter alia computational chemistry and condensed matter physics. DFT circumvents the more conceptually straightforward (but more computationally intensive) approach in which one solves the many-body Schrodinger equation. It relies instead on r...

There were many categories of near-synonymy and also many categories of antonym in ancient Chinese literary theory. The former categories were coupled with nearly synonymous popular sayings while the latter categories were coupled with antonymous popular sayings. Ancient people preferred to use these categories of sayings to define and discuss literature, just because they kept such cultural psychology and cognitive habits of thinking carefully and respecting tradition that they were reluctant to create new words and expressions to be criticized for submerging the origin of things and acting rashly, and also because they wanted to ensure that their argumentation was eloquent and profound, so that these categories could fully display the innermost essences of literary creating, and show the law of the universe that all things act mutually and perform reciprocally. This reveals the humanity root of Chinese literature, and forms one of the important characteristics of Chinese traditional literary theory.%中国古代文论中有许多近义范畴，又有许多对待范畴，前者由意义邻近的名言耦合而成，后者则由意义对待的名言耦合而成。古人好用此类名言界定与论说文学，既是出于慎终追远的文化心理和认知习惯，不愿别作新词，以冲冒被人指为汩没本源、鲁莽率意的考虑，也是为了保证立论的周洽与深刻，从而最大程度地开显文学创造的内里机理，并有以体现天地万物相偶相成的运化规律。它在在体现了中国文学的人文根性，也是构成传统文论的重要特点之一。

Full Text Available The international recruitment of health personnel appears to be lately an usual practice for some countries to cover their needs in health care. That is possible due to income differences between countries that motivate physicians to migrate. Now this is an unavoidable fact, but the resulting ethical problems cannot be ignored, like the unbalance in the developing countries healthcare systems by losing physicians. The whole practice became morally questionable with international ongoing efforts to solve it one as the recruitments codes. We will to discuss the WHO Global Code of Practice on the International Recruitment of Health Personnel from an original perspective inspired from Rawls theory of justice. The rawlsian principles we will focus on are: a. the veil of ignorance, b. the maximin strategy. With this, we offer a better look inside the code and the practice it tries to regulate.

Picard groups of tensor categories play an important role in rational conformal field theory. The Picard group of the representation category C of a rational vertex algebra can be used to construct examples of (symmetric special) Frobenius algebras in C. Such an algebra A encodes all data needed to ensure the existence of correlators of a local conformal field theory. The Picard group of the category of A-bimodules has a physical interpretation, too: it describes internal symmetries of the co...

Full Text Available Este artigo tem por objetivo apresentar a tradição da teoria crítica em Relações Internacionais. Entende-se que haja uma lacuna nos debates teóricos com a reduzida atenção dedicada a essa tradição no Brasil. O revigoramento dos debates teóricos contribui para o enfraquecimento das tradições teóricas convencionais. O papel da teoria crítica nessa tendência é primordial. A teoria crítica da Escola de Frankfurt é examinada como precursora filosófica e metateórica da teoria crítica em Relações Internacionais. Em seguida, as bases epistemológicas dos desafios da teoria crítica às teorias convencionais são apresentadas, com ênfase especial dedicada ao trabalho de Robert W. Cox. O pensamento neogramsciano é inspecionado à luz da busca pela transformação social nas relações internacionais. A vertente da teoria crítica internacional é vista como fonte de inspiração para muitos autores que trabalham com a emancipação. Examina-se a produção de Andrew Linklater por representar a busca por transformação das comunidades políticas por meio da expansão de suas fronteiras morais. Em seguida, busca-se uma avaliação crítica dos impactos trazidos pela teoria crítica ao campo de estudos das Relações Internacionais. Conclui-se que a teoria crítica tem méritos na guinada das discussões teóricas em direção a questionamentos ontológicos e epistemológicos, debate esse que tem caracterizado esse campo de estudo nas últimas décadas, por meio da exposição das limitações conseqüentes do domínio das teorias convencionais. Não obstante, a associação da teoria crítica ao pós-positivismo epistemológico constitui atitude premeditada.This article aims to present Critical Theory in International Relations.

PREFACE: 17th International Conference on Recent Progress in Many-Body Theories (MBT17)
Reinholz, Heidi; Boronat, Jordi
2014-08-01
These are the proceedings of the XVII International Conference on Recent Progress in Many-Body Theories, which was held from 8-13 September 2013 in Rostock, Germany. The conference continued the triennial series initiated in Trieste in 1978 and was devoted to new developments in the field of many-body theories. The conference series encourages the exchange of ideas between physicists working in such diverse areas as nuclear physics, quantum chemistry, lattice Hamiltonians or quantum uids. Many-body theories are an integral part in different fields of theoretical physics such as condensed matter, nuclear matter and field theory. Phase transitions and macroscopic quantum effects such as magnetism, Bose-Einstein condensation, super uidity or superconductivity have been investigated within ultra-cold gases, finite systems or various nanomaterials. The conference series on Recent Progress in Many-Body Theories is devoted to foster the interaction and to cross-fertilize between different fields and to discuss future lines of research. The topics of the 17th meeting were Cluster Physics Cold Gases High Energy Density Matter and Intense Lasers Magnetism New Developments in Many-Body Techniques Nuclear Many-Body and Relativistic Theories Quantum Fluids and Solids Quantum Phase Transitions Topological Insulators and Low Dimensional Systems. 109 participants from 20 countries participated. 44 talks and 61 posters werde presented. As a particular highlight of the conference, The Eugene Feenberg Memorial Medal for outstanding results in the field of many-body theory and The Hermann Kümmel Early Achievement Award in Many-Body Physics for young scientists in that field were awarded. The Feenberg Medal went jointly to Patrick Lee (MIT, USA) for his fundamental contributions to condensed-matter theory, especially in regard to the quantum Hall effect, to universal conductance uctuations, and to the Kondo effect in quantum dots, and Douglas Scalapino (UC Santa Barbara, USA) for his
The Role of Theory and Modeling in the International Living with a Star Program
Hesse, M.
2004-01-01
Today, theory and modeling play a critical role in our quest to understand the connection between solar eruptive phenomena, and their impacts in interplanetary space and in the near-Earth space environment. This new role is based on two developments, one related to the goal of basic physical understanding, and the other to space weather-related applications. When targeting physical our focus is shifting away from investigations aiming at basic discoveries, to missions and studies that address our basic understanding of processes we know to be important. For these studies, theory and models provide physical explanations that need to be verified or falsified by empirical evidence. Within this paradigm, a much more tight integration between theory modeling, and space flight mission design and execution is not only beneficial, but essential. One of the prime objectives of space weather research, on the other hand, is the prediction of space environmental conditions for the benefit of humans and their assets in near-Earth space and on the ground, as well as on solar system bodies like Mars that are of interest to exploration by humans. By its very nature, prediction requires modeling, which, in turn, requires understanding. We will present an overview of the role of theory and modeling within the International Living With a Star program. Specifically, we will focus on an assessment of present-day and future capabilities, as well as on strategies for tight integration of theory and modeling in space science investigations.

An International Summer School on Selected Topics in Nuclear Theory was held during the period 20 August to 9 September 1962 in the Low Tatra Mountains, Czechoslovakia, under the auspices of the Nuclear Research Institute of the Czechoslovak Academy of Sciences, with financial support from the International Atomic Energy Agency. In view of the wide interest of the seven topics considered there and of the speed with which the field of theoretical physics is developing, the Agency decided to make available its facilities for rapid publication and to publish the lectures under its own imprint; however, all editorial and composition work has been performed under the supervision of the general editor. Dr. F. Janouch of the Nuclear Research Institute of the Czechoslovak Academy of Sciences. The problem of keeping in touch with the rapidly changing but fundamental field of theoretical physics is a difficult one, particularly for scientists in the developing countries. It is hoped that such publications as the present one and the companion volume containing the lectures presented at the Agency's Seminar on Theoretical Physics at Trieste w ill help, at least in a modest fashion, to overcome these difficulties.

We describe a method for obtaining analytical solutions and numerical results for three-dimensional one-speed neutron transport problems in a half-space containing a variety of source shapes which emit neutrons mono-directionally in the direction away from the surface. Thus this paper is a supplement to Williams [Williams, M.M.R., 2009, Three-dimensional transport theory: an analytical solution for the internal beam searchlight problem I. Annals of Nuclear Energy 36, 767-783]. For example, we consider a point source, a ring source and a disk source, and calculate the surface scalar flux as a function of the radial co-ordinate when the source is at a fixed distance from the surface. The results are in full agreement with the work of Ganapol and Kornreich [Ganapol, B.D., Kornreich, D.E., this issue. Three-dimensional transport theory: an analytical solution for the internal beam searchlight problem II. Annals of Nuclear Energy]. Diffusion theory results are also included.

A theory of international bioethics: the negotiable and the non-negotiable.
Baker, Robert
1998-09-01
The preceding article in this issue of the Kennedy Institute of Ethics Journal presents the argument that "moral fundamentalism," the position that international bioethics rests on "basic" or "fundamental" moral prinicples that are universally accepted in all eras and cultures, collapses under a variety of multicultural and postmodern critiques. The present article looks to the contractarian tradition of Hobbes and Locke -- as reinterpreted by David Gauthier, Robert Nozick, and John Rawls -- for an alternative justification for international bioethics. Drawing on the central themes of this tradition, it is argued that international bioethics can be rationally reconstructed as a negotiated moral order that respects culturally and individually defined areas of nonnegotiability. Further, the theory of a negotiated moral order is consistent with traditional ideals about human rights, is flexible enough to absorb the genuine insights of multiculturalism and postmodernism, and yet is strong enough to justify transcultural and transtemporal moral judgments, including the condemnation of the Nazi doctors at Nuremberg. This theory also is consistent with the history of the ethics of human subjects experimentation and offers insights into current controversies such as the controversy over changing the consent rule for experiments in emergency medicine and the controversy over exempting certain clinical trials of inexpensive treatments for preventing the perinatal transmission of AIDS from the ethical standards of the sponsoring country.

A generalized continuum theory with internal corner and surface contact interactions
Fosdick, Roger
2016-03-01
We consider a classical derivation of a continuum theory, based on the fundamental balance laws of mass and momenta, for a body with internal corner and surface contact interactions. The balances of mass and linear and angular momentum are applied to the arbitrary parts of a continuum which supports non-classical internal corner and surface contact interactions. The form of the specific corner contact interaction force measured per unit length of the corner is derived. A generalized form of Cauchy's stress theorem is obtained, which shows that the surface traction on an oriented surface depends in a specific way on both the oriented unit normal as well as the curvature of the surface. An explicit form of the surface-couple traction which acts on every oriented surface is obtained. Two fields in the continuum, which are denoted as stress and hyperstress fields, are shown to exist, and their role in representing the surface traction and the surface-couple traction is identified. Finally, the field equations for this theory are determined, and a fundamental power theorem is derived. In the absence of internal corner and surface-couple traction interactions, the equations of classical continuum mechanics are recovered. There is no appeal to any `principle of virtual power' in this work.

A policy capturing questionnaire was used to elicit responses from consumers using a convenience sampling technique. A total of 7500 responses were obtained from 150 participating respondent in 50 different scenario cases. Data is analyzed using Multi-Group Structural Equation Modeling. The study finds that the Theory of Planned Behavior (TPB is not completely valid to explain both the behavioral intention of Muslim consumers in Indonesia to seek information about the Halal certification of a product and to cancel their purchase if the product did not have Halal certification. Differences in magnitude and significance of causal relationships exist between different product categories.
Virtue Ethics: The Misleading Category
Martha Nussbaum
1998-01-01
Virtue ethics is frequently considered to be a single category of ethical theory, and a rival to Kantianismand Utilitarianism. I argue that this approach is a mistake, because both Kantians and Utilitarians can, and do, have an interest in the virtues and the forrnation of character. But even if we focus on the group of ethical theorists who are most commonly called "virtue theorists" because they reject the guidance of both Kantianism and Utilitarianism, and derive inspiration from ancient G...

In Japan, 'All Japan' strategy for nuclear power exports, which arranges engineering companies and electric utilities to sell nuclear power plants providing engineering, procurement, construction and operation abroad, with governmental support of expanded trade insurance, is strongly promoted today as a part of Japan's national growth strategy. However, 'All Japan' strategy generates some problems because the strategy does not consider difference of business strategies concerning international development of each enterprise. This report identifies problems of 'All Japan' strategy based on environmental scanning of major three categories of businesses, which are big nuclear technology companies, vendors and electric utilities constituting nuclear power industry. And this report proposes the way to improve the strategy as follows to resolve those problems. 1) It is necessary to assess the risk of the project that is to be undertaken by 'All Japan' approach carefully. 2) Governmental support for vendors is also needed because the vendors are source of strength of international development of the nuclear industry in Japan. 3) Where the cooperation among the electric utilities is necessary, imposing the risk burden on the utilities should be avoided. 4) It is necessary for government to take measures about 'Weakness' and 'Threat' that each category of business commonly faces.

Critical social theory, including the work of Jurgen Habermas, provides a valuable lens for viewing phenomena within their sociopolitical contexts. According to Habermas, the lives and experiences of individuals, groups, and societies in the western world are strongly influenced by the forces of economics and power. These influences may interfere with communication and, therefore, the transmission and regeneration of culture and its meaning. This article describes the experience of initiating an international exchange program at a university school of nursing in the eastern United States. Examined through the lens of Habermas' theory, constraints and obstacles encountered in this process are revealed. Specifically, the inhibiting influence that politics and economics may have on active communication and the potential benefits of shared meaning and understanding achieved by interaction and discourse are examined.

We present two efficient and intruder-free methods for treating dynamic correlation on top of general multi-configuration reference wave functions---including such as obtained by the density matrix renormalization group (DMRG) with large active spaces. The new methods are the second order variant of the recently proposed multi-reference linearized coupled cluster method (MRLCC) [S. Sharma, A. Alavi, J. Chem. Phys. 143, 102815 (2015)], and of N-electron valence perturbation theory (NEVPT2), with expected accuracies similar to MRCI+Q and (at least) CASPT2, respectively. Great efficiency gains are realized by representing the first-order wave function with a combination of internal contraction (IC) and matrix product state perturbation theory (MPSPT). With this combination, only third order reduced density matrices (RDMs) are required. Thus, we obviate the need for calculating (or estimating) RDMs of fourth or higher order; these had so far posed a severe bottleneck for dynamic correlation treatments involving t...

Analytical nuclear gradients for fully internally contracted complete active space second-order perturbation theory (CASPT2) are reported. This implementation has been realized by an automated code generator that can handle spin-free formulas for the CASPT2 energy and its derivatives with respect to variations of molecular orbitals and reference coefficients. The underlying complete active space self-consistent field and the so-called Z-vector equations are solved using density fitting. With full internal contraction the size of first-order wave functions scales polynomially with the number of active orbitals. The CASPT2 gradient program and the code generator are both publicly available. This work enables the CASPT2 geometry optimization of molecules as complex as those investigated by respective single-point calculations.

The results of investigations in parastatistical theories and in their applications to the internal symmetries of elementary particles are present. The paraquantization and the 'generalized paraquantization' (of Levine and Tomozawa) of the relativistic Schroedinger wave equations for non-zero mass and arbitrary spin (s), involving locally covariant wave functions, Ψo,s+ Ψs,o are executed, and the restrictions resulting from the criterion of microscopic causality and the manner of establishment of the connection between spin and statistics in these quantizations are explicitly demonstrated.

British International Relations Theory (IRT) is distinguished by a concern with institutions and norms, and by an emphasis on history, philosophy and law rather than the formal methods of the social sciences. In both respects, but especially the latter, it differs from American IRT. The origins of British IRT are traced and the importance of the ‘English School’ is stressed partly because of the work it stimulates but also because of its role as a brand, which helps to establish the independe...
Stable Postnikov data of Picard 2-categories
Gurski, Nick; Johnson, Niles; Osorno, Angélica M.; Stephan, Marc
2016-01-01
Picard 2-categories are symmetric monoidal 2-categories with invertible 0-, 1-, and 2-cells. The classifying space of a Picard 2-category $\\mathcal{D}$ is an infinite loop space, the zeroth space of the $K$-theory spectrum $K\\mathcal{D}$. This spectrum has stable homotopy groups concentrated in levels 0, 1, and 2. In this paper, we describe part of the Postnikov data of $K\\mathcal{D}$ in terms of categorical structure. We use this to show that there is no strict skeletal Picard 2-category who...
Internal pressure buckling of very thin torispherical shells. A comparison of experiment and theory
International Nuclear Information System (INIS)
The bottom head of the primary vessel of some LMFBR's is a thin torispherical shell. The internal pressure loading on the head consists of the weight of the sodium contents plus any superimposed gas pressure. Depending on the design of the bottom head, it can fail by (i) elastic or elastic-plastic circumferential buckling or (ii) the development of yield 'hinges' and gross deformation of the shell. At the present time, there is no generally-accepted theory of asymmetric elastic-plastic shell buckling due to internal pressure. However, the experimental-theoretical correlation for external pressure buckling looks promising-as evidenced by the recent paper by Bushnell and Galletly. In this paper a review is given of previous work on internal pressure buckling of torispheres-some of it of very recent origin. The author's experiments on a limited number of machined, stress-relieved, cylinder-torisphere combinations which were subjected to increasing internal pressure are then described. (Auth.)
A Higher-Order Calculus for Categories

Cáccamo, Mario José; Winskel, Glynn

A calculus for a fragment of category theory is presented. The types in the language denote categories and the expressions functors. The judgements of the calculus systematise categorical arguments such as: an expression is functorial in its free variables; two expressions are naturally isomorphic...... in their free variables. There are special binders for limits and more general ends. The rules for limits and ends support an algebraic manipulation of universal constructions as opposed to a more traditional diagrammatic approach. Duality within the calculus and applications in proving continuity...... are discussed with examples. The calculus gives a basis for mechanising a theory of categories in a generic theorem prover like Isabelle....
Valuation, categories and attributes.
Directory of Open Access Journals (Sweden)
Inna Galperin
Full Text Available Existing research on categories has only examined indirectly the value associated with being a member of a category relative to the value of the set of attributes that determine membership in that category. This study uses survey data to analyze consumers' preferences for the "organic" label versus for the attributes underlying that label. We found that consumers generally preferred products with the category label to those with the attributes required for the organic label but without the label. We also found that the value accorded to the organic label increased with the number of attributes that an individual associated with the category. Category membership nevertheless still had greater value than even that of the sum of the attributes associated with it.

In this paper we give a construction of phantom categories, i.e. admissible triangulated subcategories in bounded derived categories of coherent sheaves on smooth projective varieties that have trivial Hochschild homology and trivial Grothendieck group. We also prove that these phantom categories are phantoms in a stronger sense, namely, they have trivial K-motives and, hence, all their higher K-groups are trivial too.

We report the development of the theory and computer program for analytical nuclear energy gradients for (extended) multi-state complete active space perturbation theory (CASPT2) with full internal contraction. The vertical shifts are also considered in this work. This is an extension of the fully internally contracted CASPT2 nuclear gradient program, recently developed for a state-specific variant by us [MacLeod and Shiozaki, J. Chem. Phys. 142, 051103 (2015)]; in this extension, the so-called {\\lambda} equation is solved to account for the variation of the multi-state CASPT2 energies with respect to the change in the amplitudes obtained in the preceding state-specific CASPT2 calculations, and the Z-vector equations are modified accordingly. The program is parallelized using the MPI3 remote memory access protocol that allows us to perform efficient one-sided communication. The optimized geometries of the ground and excited states of a copper corrole and benzophenone are presented as numerical examples. The c...

In many real-world problems, rare categories (minority classes) play essential roles despite their extreme scarcity. The discovery, characterization and prediction of rare categories of rare examples may protect us from fraudulent or malicious behavior, aid scientific discovery, and even save lives. This book focuses on rare category analysis, where the majority classes have smooth distributions, and the minority classes exhibit the compactness property. Furthermore, it focuses on the challenging cases where the support regions of the majority and minority classes overlap. The author has devel
Internal stucture of clusters in $^{112-122}$Ba nuclei within relativistic mean field theory
Bhuyan, M; Arumugam, P; Gupta, Raj K
2009-01-01
We study the clustering structure and the internal or sub-structure of clusters in $^{112-122}$Ba nuclei within the framework of relativistic mean field theory in an axially deformed cylindrical co-ordinate. We calculate the total density distribution, and the individual neutrons and protons density distributions. From the analysis of the clustering confugurations of the density distributions of various shapes, we find different sub-structures inside the Ba nuclei considered here. The important step, carried out for the first time, is the counting of number of protons and neutrons present in the clustering region(s). $^{12}$C is shown to consitute the cluster configuration of Ba nuclei in most cases, with $^{2,3}$H and $^4$He constituting the neck between two fissioning symmetrical fragments.

As a particular type of communicative act and a special mode of inter -cultural activity , interpretation is characteristic of a variety of unique features , among which promptitude claims that the interpreter should transfer the source message into the target within the time required , which in turn brings about many difficulties for the interpreter . To facilitate the interpreter (s ) conveying the lexical information to the receptive party as a whole as quickly and accurately as possible , this paper , based on the prototypical - categorial theory , thus is outlined to specifically propose the strategies for wording equivalence in interpretation , say , “expand the semantic category and enlarge the correspondence range and margin” , so as to achieve the shortcut of transference from the source language to the target one .

The present volume contains the texts of the invited talks delivered at the Fifth International Conference on Recent Progress in Many-Body Theories held in Oulu, Finland during the period 3-8 August 1987. The general format and style of the meeting followed closely those which had evolved from the earlier conferences in the series: Trieste 1978, Oaxtepec 1981, Altenberg 1983 and San Francisco 1985. Thus, the conferences in this series are in tended, as far as is practicable, to cover in a broad and balanced fashion both the entire spectrum of theoretical tools developed to tackle the quan tum many-body problem, and their major fields of· application. One of the major aims of the series is to foster the exchange of ideas and techniques among physicists working in such diverse areas of application of many-body theories as nucleon-nucleon interactions, nuclear physics, astronomy, atomic and molecular physics, quantum chemistry, quantum fluids and plasmas, and solid-state and condensed matter physics.

The ability to categorize objects and events in the world around us is a fundamental and critical aspect of human learning. We trained healthy adults on a probabilistic category-learning task in two different training modes. The aim of this study was to see whether either form of probabilistic category learning (feedback or observational) undergoes subsequent enhancement during sleep. Our results suggest that after training, a good night of sleep can lead to improved performance the following...
Higher-order weakly nonlinear theory for internal waves in three-layer fluid
Kurkina, O. E.; Kurkin, A. A.; Rouvinskaya, E. A.
2012-04-01
Three-layer stratifications are proved to be a proper approximation of sea water density profile in some basins in the World Ocean with specific hydrological conditions. Some shallow basins such as the Baltic Sea and some river estuaries have more or less continuous three-layer vertical structure caused by the interplay of fresh water discharge to the surface and salt water intrusion in the bottom layers. In order to describe the basic features of the internal wave field in such environments it is necessary to introduce a three-layer model. Such models are considerably more complex than the most popular two-layer systems; however, they represent new dynamical effects and allow for much more analytical progress in their studies compared to the fully stratified situation. In the present study two modes of long internal gravity waves in a three-layer fluid are investigated in the framework of higher-order nonlinear evolutionary equations derived with the use of asymptotic procedure from the governing Euler equations for inviscid incompressible layered medium with "rigid lid" and horizontal impermeable bottom. The equations are written upto the fifth order of the perturbation theory for both interfaces for the waves of both modes: first (fast mode) and second (slow mode, so-called double-humped or varicose). For each equation the coefficients of nonlinearity, dispersion and nonlinear dispersion are expressed explicitly in terms of parameters of this fluid configuration. The behavior and signs of the coefficients are analyzed. The necessary order of the equations is discussed and determined for each case. A few nonlinear asymptotic transformations are proposed to reduce higher-order equations to simpler lower-order or well-known integrable equations (Korteweg - de Vries, Gardner equations). Special attention is paid to the situations when the nonlinear terms of lower orders of perturbation theory can vanish. For such situations particular rescaling is performed in order
Modelling the acquisition of syntactic categories

This research represents an attempt to model the child’s acquisition of syntactic categories. A computational model, based on the EPAM theory of perception and learning, is developed. The basic assumptions are that (1) syntactic categories are actively constructed by the child using distributional learning abilities; and (2) cognitive constraints in learning rate and memory capacity limit these learning abilities. We present simulations of the syntax acquisition of a single subject, where t...

, directly generating radiations. The observed diagram of the heat radiation, the relation “mass-luminosity-radius”, cannot be explained by standard physical laws. Stars exist in just those conditions where classical laws are broken, and a special mechanism for the generation of energy becomes possible. Those conditions are determined by the main direction on the diagram and the main point located in the direction. Physical coordinates of the main point have been found using observational data. The constants (physical coordinates should be included in the theory of the internal constitution of stars which pretend to adequately account for observational data. There in detail manifests the inconsistency of the explanations of stellar energy as given by nuclear reactions, and also calculations as to the percentage of hydrogen and helium in stars. Also considered are peculiarities of some sequences in the Russell-Hertzsprung diagram, which are interesting from the theoretical viewpoint.

Benchmarking of electricity networks has a key role in sharing the benefits of efficiency improvements with consumers and ensuring regulated companies earn a fair return on their investments. This paper analyses and contrasts the theory and practice of international benchmarking of electricity transmission by regulators. We examine the literature relevant to electricity transmission benchmarking and discuss the results of a survey of 25 national electricity regulators. While new panel data techniques aimed at dealing with unobserved heterogeneity and the validity of the comparator group look intellectually promising, our survey suggests that they are in their infancy for regulatory purposes. In electricity transmission, relative to electricity distribution, choosing variables is particularly difficult, because of the large number of potential variables to choose from. Failure to apply benchmarking appropriately may negatively affect investors’ willingness to invest in the future. While few of our surveyed regulators acknowledge that regulatory risk is currently an issue in transmission benchmarking, many more concede it might be. In the meantime new regulatory approaches – such as those based on tendering, negotiated settlements, a wider range of outputs or longer term grid planning – are emerging and will necessarily involve a reduced role for benchmarking. -- Highlights: •We discuss how to benchmark electricity transmission. •We report survey results from 25 national energy regulators. •Electricity transmission benchmarking is more challenging than benchmarking distribution. •Many regulators concede benchmarking may raise capital costs. •Many regulators are considering new regulatory approaches

This book presents a selection of papers presented to the Second Inter national Symposium on Semi-Markov Models: Theory and Applications held in Compiegne (France) in December 1998. This international meeting had the same aim as the first one held in Brussels in 1984 : to make, fourteen years later, the state of the art in the field of semi-Markov processes and their applications, bring together researchers in this field and also to stimulate fruitful discussions. The set of the subjects of the papers presented in Compiegne has a lot of similarities with the preceding Symposium; this shows that the main fields of semi-Markov processes are now well established particularly for basic applications in Reliability and Maintenance, Biomedicine, Queue ing, Control processes and production. A growing field is the one of insurance and finance but this is not really a surprising fact as the problem of pricing derivative products represents now a crucial problem in economics and finance. For example, stochastic mode...

If a prime goal of energy policy is to achieve energy security, why is there a controversy over the proposed Keystone XL pipeline, designed to deliver new supplies of oil from within North America? This Viewpoint seeks answers in the debate over the underlying purposes of energy policy: how does one answers the question “what do we want from energy policy?” Perceptions of feasible answers and policy options change over time, as witnessed in the 1970s. Analogous shifts in opinion are changing today's policy debates and widening the contradictions in policy purposes. Attention to the existence of these contradictions, without illusions, is necessary to meet the policy challenges of the future effectively. - Highlights: • We apply international relations theory to explain the persistence of the Keystone controversy. • Key question relates to policy purposes: “what do we want from energy policy?” • Alternative purposes: maximizing economic growth or ensuring environmental sustainability. • 1970s US cases show how perceptions of each purpose's relative feasibility shift. • Different purposes generate different attitudes to policies that result in higher oil prices

PREFACE: The 5th International Symposium on Quantum Theory and Symmetries (QTS5)
Gadella, M.; Izquierdo, J. M.; Kuru, S.; Negro, J.; del Olmo, M. A.
2008-08-01
This special issue of Journal of Physics A: Mathematical and Theoretical appears on the occasion of the 5th International Symposium on Quantum Theory and Symmetries (QTS5), held in Valladolid, Spain, from 22-28 July 2007. This is the fith in a series of conferences previously held in Goslar (Germany) 1999, QTS1; Cracow (Poland) 2001, QTS2; Cincinnati (USA) 2003, QTS3; and Varna (Bulgaria) 2005, QTS4. The QTS5 symposium gathered 181 participants from 39 countries working in different fields of theoretical physics. The spirit of the QTS conference series is to join researchers in a wide variety of topics in theoretical physics, as a way of making accessible recent results and the new lines of different fields. This is based on the feeling that it is good for a physicist to have a general overview as well as expertise in his/her own field. There are many other conferences devoted to specific topics, which are of interest to gain deeper insight in many technical aspects and that are quite suitable for discussions due to their small size. However, we believe that general conferences like this are interesting and worth keeping. We like the talks, in both plenary and parallel sessions, which are devoted to specific topics, to be prepared so as to be accessible to any researcher in any branch of theoretical physics. We think that this objective is compatible with rigour and high standards. As is well known, similar methods and techniques can be useful for many problems in different fields. We hope that this has been appreciated during the sessions of the QTS5 conference. The QTS5 conference offered the following list of topics: 1. Symmetries in string theory, quantum gravity and related topics 2. Symmetries in quantum field theories, conformal and related field theories, lattice and noncommutative theories, gauge theories 3.Quantum computing, information and control 4. Foundations of quantum theory 5. Quantum optics, coherent states, Wigner functions 6. Dynamical and

A closed form analytical solution is obtained for a three-dimensional transport theory problem, namely that of a line source in a half-space in one-speed transport theory with an internally reflecting surface. The theory is developed by using Fourier transforms in the transverse directions and a Laplace transform in the axial direction, together with the Wiener-Hopf technique. Both specular and diffuse internal reflection are considered and it is shown that a closed form solution is not available for the specular case but is available for the diffuse case. The surface particle scalar intensity and current are obtained and their sensitivity to absorption and the reflection coefficient are assessed. We also obtain a number of analytic asymptotic estimates for the intensity valid at large distances from the source. Diffusion theory is also employed and compared numerically with the transport solution. In general, diffusion theory gives very satisfactory results within its regions of limitation. We also offer this paper as an exercise in analytical transport theory; an aspect of reactor physics which is not often seen in recent times

Purchasing power parity theory in a model without international trade of goods
Läufer, Nikolaus K. A.
1980-01-01
In recent discussions it frequently occurs that the Purchasing Power Parity Theory is identified with Jevons law of one price. By pointing to real world obstacles working against perfect goods arbitrage it is then erroneously concluded that the Purchasing Power Parity Theory cannot be valid while a dinstiction between an absolute version and a relative version of the Purchasing Power Parity Theory is neglected. In the present paper it is shown that the Purchasing Power Parity Theory in the re...
Algebras of higher operads as enriched categories II
Batanin, Michael; Weber, Mark
2009-01-01
One of the open problems in higher category theory is the systematic construction of the higher dimensional analogues of the Gray tensor product. In this paper we continue the work of [7] to adapt the machinery of globular operads [4] to this task. The resulting theory includes the Gray tensor product of 2-categories and the Crans tensor product [12] of Gray categories. Moreover much of the previous work on the globular approach to higher category theory is simplified by our new foundations, and we illustrate this by giving an expedited account of many aspects of Cheng's analysis [11] of Trimble's definition of weak n-category. By way of application we obtain an "Ekmann-Hilton" result for braided monoidal 2-categories, and give the construction of a tensor product of A-infinity algebras.
Visual memory needs categories
Olsson, Henrik; Poom, Leo
2005-01-01
Capacity limitations in the way humans store and process information in working memory have been extensively studied, and several memory systems have been distinguished. In line with previous capacity estimates for verbal memory and memory for spatial information, recent studies suggest that it is possible to retain up to four objects in visual working memory. The objects used have typically been categorically different colors and shapes. Because knowledge about categories is stored in long-t...

Distributed word representations have been demonstrated to be effective in capturing semantic and syntactic regularities. Unsupervised representation learning from large unlabeled corpora can learn similar representations for those words that present similar co-occurrence statistics. Besides local occurrence statistics, global topical information is also important knowledge that may help discriminate a word from another. In this paper, we incorporate category information of documents in the l...

Dissociative Recombination is one of the outcomes of collisions between electrons and molecular ions. This reaction dominates many plasmas, dense as well as dilute. Therefore, knowledge about this reaction is highly relevant for astrophysics, atmospheric sciences, (non-)reactive plasmas, and fusion plasmas. A theoretical description of this process requires intensive ab initio quantum chemistry calculations as well as a detailed description of the electron collision process. The high density of states near the ionization energy of molecules renders calculations extremely difficult and complex. In experiments, both discharge and flowing afterglow experiments and fast beam and ion storage ring experiments, a steady development can be seen towards more detailed studies often at the quantum state resolved level including product internal state identification and very recently detailed vector properties such as fragment angular distributions. Thanks to an efficient interplay between experiment and theory dissociative recombination has progressed significantly over the last few years. The Seventh International Conference on Dissociative Recombination: Theory, Experiments, and Applications (DR2007) was organized by the Institute of Molecules and Materials at the Radboud University Nijmegen, The Netherlands and was held on the Wadden Island of Ameland. Earlier conferences in this series were held at Lake Louise, Alberta, Canada (1988), Saint Jacut, Bretagne, France (1992), Ein Gedi, Israel (1995), Nässlingen, Stockholm Archipelago, Sweden (1999), Chicago, USA, as part of the American Chemical Society meeting (2001), and in Mosbach, Germany (2004). Ameland and the Resort d'Amelander Kaap was chosen in the spirit of previous dissociative recombination conferences. It turned out to be a venue where discussions about dissociative recombination could take place around the clock both inside and outside while walking through dunes and on the beach. The conference was made
Virtue Ethics: The Misleading Category
Directory of Open Access Journals (Sweden)
Martha Nussbaum
1998-12-01
Full Text Available Virtue ethics is frequently considered to be a single category of ethical theory, and a rival to Kantianismand Utilitarianism. I argue that this approach is a mistake, because both Kantians and Utilitarians can, and do, have an interest in the virtues and the forrnation of character. But even if we focus on the group of ethical theorists who are most commonly called "virtue theorists" because they reject the guidance of both Kantianism and Utilitarianism, and derive inspiration from ancient Greek ethics, there is little unity to this group. Although there is a thin common ground that links all the group's members - a focus on the formation of character, on the nature of the passions, and on choice over the whole course of life - there are also crucial differences among them.

Category Variability Effect in Category Learning with Auditory Stimuli
Directory of Open Access Journals (Sweden)
Lee-Xieng eYang
2014-10-01
Full Text Available The category variability effect refers to that people tend to classify the midpoint item between two categories as the category more variable. This effect is regarded as evidence against the exemplar model, such as GCM (Generalized Context Model and favoring the rule model, such as GRT (i.e., the decision bound model. Although this effect has been found in conceptual category learning, it is not often observed in perceptual category learning. To figure out why the category variability effect is seldom reported in the past studies, we propose two hypotheses. First, due to sequence effect, the midpoint item would be classified as different categories, when following different items. When we combine these inconsistent responses for the midpoint item, no category variability effect occurs. Second, instead of the combination of sequence effect in different categorization conditions, the combination of different categorization strategies conceals the category variability effect. One experiment is conducted with single tones of different frequencies as stimuli. The collected data reveal sequence effect. However, the modeling results with the MAC model and the decision bound model support that the existence of individual differences is the reason for why no category variability effect occurs. Three groups are identified by their categorization strategy. Group 1 is rule user, placing the category boundary close to the low-variability category, hence inducing category variability effect. Group 2 takes the MAC strategy and classifies the midpoint item as different categories, depending on its preceding item. Group 3 classifies the midpoint item as the low-variability category, which is consistent with the prediction of the decision bound model as well as GCM. Nonetheless, our conclusion is that category variability effect can be found in perceptual category learning, but might be concealed by the averaged data.

Nonassociative geometry in quasi-Hopf representation categories II: Connections and curvature
Barnes, Gwendolyn E.; Schenkel, Alexander; Szabo, Richard J.
2016-08-01
We continue our systematic development of noncommutative and nonassociative differential geometry internal to the representation category of a quasitriangular quasi-Hopf algebra. We describe derivations, differential operators, differential calculi and connections using universal categorical constructions to capture algebraic properties such as Leibniz rules. Our main result is the construction of morphisms which provide prescriptions for lifting connections to tensor products and to internal homomorphisms. We describe the curvatures of connections within our formalism, and also the formulation of Einstein-Cartan geometry as a putative framework for a nonassociative theory of gravity.

The first of its kind, this book presents a widely accessible exposition of topos theory, aimed at the philosopher-logician as well as the mathematician. It is suitable for individual study or use in class at the graduate level (it includes 500 exercises). It begins with a fully motivated introduction to category theory itself, moving always from the particular example to the abstract concept. It then introduces the notion of elementary topos, with a wide range of examples and goes on to develop its theory in depth, and to elicit in detail its relationship to Kripke's intuitionistic semantics,
Dewey, Peirce, and the Categories of Learning
Wojcikiewicz, Steven K
2010-01-01
John Dewey proposes the “educative” experience as the goal of instruction. Yet, in focusing on the educative experience, Dewey may discount other sorts of learning which occur in school, and indeed in life. This piece proposes a recapitulation of Dewey’s theory through Peirce’s categorical system of experience, leading to three categories of learning. The three proposed categories, “accepting,” “analytical,” and “evaluative,” correspond roughly to learning “what”, learning “how”, and learning...

Category vs. Object Knowledge in Category-based Induction
Murphy, Gregory L.; Ross, Brian H.
2010-01-01
In one form of category-based induction, people make predictions about unknown properties of objects. There is a tension between predictions made based on the object’s specific features (e.g., objects above a certain size tend not to fly) and those made by reference to category-level knowledge (e.g., birds fly). Seven experiments with artificial categories investigated these two sources of induction by looking at whether people used information about correlated features within categories, sug...

Shushu is a Turkish Cypriot drag performance artist and the article begins with a discussion of a short film about him by a Greek Cypriot playwright, film maker, and gay activist. The film is interesting in its own right as a documentary about a complex personality, but it is also relevant to wider discussion of sexual and gender identity and categorization in a country divided by history, religion, politics, and military occupation. Shushu rejects easy identification as gay or transgender, or anything else. He is his own self. But refusing a recognized and recognizable identity brings problems, and I detected a pervasive mood of melancholy in his portrayal. The article builds from this starting point to explore the problematic nature of identities and categorizations in the contemporary world. The analysis opens with the power of words and language in defining and classifying sexuality. The early sexologists set in motion a whole catalogue of categories which continue to shape sexual thinking, believing that they were providing a scientific basis for a more humane treatment of sexual variations. This logic continues in DSM-5. The historical effect, however, has been more complex. Categorizations have often fixed individuals into a narrow band of definitions and identities that marginalize and pathologize. The emergence of radical sexual-social movements from the late 1960s offered new forms of grassroots knowledge in opposition to the sexological tradition, but at first these movements worked to affirm rather than challenge the significance of identity categories. Increasingly, however, identities have been problematized and challenged for limiting sexual and gender possibilities, leading to the apparently paradoxical situation where sexual identities are seen as both necessary and impossible. There are emotional costs both in affirming a fixed identity and in rejecting one. Shushu is caught in this dilemma, leading to the pervasive sense of loss that shapes the

class="ArticleText">Compared to the discipline of international law, scholars of physics are blessed. While the principles of classical mechanics were theorized several centuries ago, quantum theory and the theory of relativity offer supplementary ways for describing how material objects and energy interact where classical mechanics does not provide an explanation. Thus, even in the absence of an all-comprising “world theory”, physicists have a wide array of workable theories at their service. By contrast, the “classical mechanics” of international law, i.e. the explanation of the most basic causal relationships between international legal norms and the behaviour of states as the main subjects of international law, are still subject to deep theoretical controversies. International legal doctrine presupposes that international law does have an impact and does not aim at questioning or further explaining this assumption. Traditional legal theories that see the essence of legal normativity in the possibility to trigger mechanisms of physical constraint often come to the conclusion that international law, in the absence of central enforcement mechanisms, is at best a primitive form of law. More recent enquiries into international legal theory from very different theoretical angles come to even less uplifting conclusions. Some argue that international legal norms are either entirely devoid of content because of their inherent indeterminacy and therefore prone to be captured by special interests. Others consider international law to be merely epiphenomenal because rational states would only consent to legal norms if, and as long as, they describe a behaviour they would choose anyway because it promises higher payoffs. In particular the latter critique put forward so forcefully by Jack Goldsmith and Eric Posner sent considerable shock waves through the invisible college of international lawyers. This is the background that needs to be kept
Semidirect Products of Monoidal Categories

2015-01-01
We introduce semidirect products of monoidal categories as a categorification of semidirect products of monoids (or, perhaps more familiarly, of groups). We also introduce a weakened version of this construction, resulting in some examples of skew monoidal categories. We discuss how this construction interacts with autonomous and closed monoidal categories, and end by producing some examples of monoidal categories which are closed on only one side.

The dynamics of internal gravity waves in the ocean: theory and applications
Bulatov, Vitaly V
2013-01-01
In this paper we consider fundamental processes of the disturbance and propagation of internal gravity waves in the ocean modeled as a vertically stratified, horizontally non-uniform, and non-stationary medium. We develop asymptotic methods for describing the wave dynamics by generalizing the spatiotemporal ray-tracing method (a geometrical optics method). We present analytical and numerical algorithms for calculating the internal gravity wave fields using actual ocean parameters such as physical characteristics of the sea water, topography of its floor, etc. We demonstrate that our mathematical models can realistically describe the internal gravity wave dynamics in the ocean. Our numerical and analytical results show that the internal gravity waves have a significant impact on underwater objects in the ocean.

Type theories, logical frameworks and meta-languages form a common foundation for designing, implementing, and reasoning about formal languages and their semantics. They are central to the design of modern programming languages, certified software, and domain specific logics. More generally, they continue to influence applications in many areas in mathematics, logic and computer science. The Logical Frameworks and Meta-languages: Theory and Practice workshop aims to bring together designers, implementers, and practitioners working on these areas, and in particular about: the automation and implementation of the meta-theory of programming languages and related calculi; the design of proof assistants, automated theorem provers, and formal digital libraries building upon logical framework technology; theoretical and practical issues concerning the encoding of variable binding and fresh name generation, especially the representation of, and reasoning about, datatypes defined from binding signatures; case studies ...

Suitable tools for assessing the severity of chronic obstructive pulmonary disease (COPD) include multi-component indices and the global initiative for chronic obstructive lung disease (GOLD) categories. The aim of this study was to evaluate the dyspnoea, obstruction, smoking, exacerbation (DOSE) and the age, dyspnoea, obstruction (ADO) indices and GOLD categories as measures of current health status and future outcomes in COPD patients. This was an observational cohort study comprising 5,114 primary care COPD patients across three databases from UK, Sweden and Holland. The associations of DOSE and ADO indices with (i) health status using the Clinical COPD Questionnaire (CCQ) and St George’s Respiratory Questionnaire (SGRQ) and COPD Assessment test (CAT) and with (ii) current and future exacerbations, admissions and mortality were assessed in GOLD categories and DOSE and ADO indices. DOSE and ADO indices were significant predictors of future exacerbations: incident rate ratio was 1.52 (95% confidence intervals 1.46–1.57) for DOSE, 1.16 (1.12–1.20) for ADO index and 1.50 (1.33–1.68) and 1.23 (1.10–1.39), respectively, for hospitalisations. Negative binomial regression showed that the DOSE index was a better predictor of future admissions than were its component items. The hazard ratios for mortality were generally higher for ADO index groups than for DOSE index groups. The GOLD categories produced widely differing assessments for future exacerbation risk or for hospitalisation depending on the methods used to calculate them. None of the assessment systems were excellent at predicting future risk in COPD; the DOSE index appears better than the ADO index for predicting many outcomes, but not mortality. The GOLD categories predict future risk inconsistently. The DOSE index and the GOLD categories using exacerbation frequency may be used to identify those at high risk for exacerbations and admissions. PMID:27053297

The occurrence of alternating damage zones surrounding underground openings (commonly known as zonal disintegration) is treated as a "far from thermodynamic equilibrium" dynamical process or a nonlinear continuous phase transition phenomenon. The approach of internal variable gradient theory with diffusive transport, which may be viewed as a subclass of Landau's phase transition theory, is adopted. The order parameter is identified with an irreversible strain quantity, the gradient of which enters into the expression for the free energy of the rock system. The gradient term stabilizes the material behavior in the post-softening regime, where zonal disintegration occurs. The results of a simplified linearized analysis are confirmed by the numerical solution of the nonlinear problem.

2015 is the International Year of Light and Light-based Technologies (IYL), while the physics and chemistry Nobel Prizes 2014 are both about light. The work leading to the two prizes share the same basic theoretical foundation: when an electron jumps from a higher energy level to a lower energy level, the energy difference is transformed into a photon. This basic way of light generation is a key part of the Old Quantum Theory. Interestingly, the date of announcing the 2014 Nobel Prize for physics coincided with the birthdays of Niels Bohr and, especially, of Planck's blackbody radiation formula. In connection with the two 2014 Nobel Prizes, we recall the development of the Old Quantum Theory by Planck, Einstein and Bohr.
The Friedmann Universe and Compact Internal Spaces in Higher-Dimensional Gravity Theories

We consider gravity theories in $4+N$ dimensions which are governed by the Lagrangian written as an extended Gauss-Bonnet density. We can find a naturally generalized Einstein gravity where the maximal symmetric compactification leads to vanishing four-dimensional cosmological constant in the static limit. A later stage in the generalized Kaluza-Klein cosmology is also examined.

The equilibrium theory of inhomogeneous polymers (international series of monographs on physics)
Fredrickson, Glenn
2013-01-01
The Equilibrium Theory of Inhomogeneous Polymers provides an introduction to the field-theoretic methods and computer simulation techniques that are used in the design of structured polymeric fluids. By such methods, the principles that dictate equilibrium self-assembly in systems ranging from block and graft copolymers, to polyelectrolytes, liquid crystalline polymers, and polymer nanocomposites can be established. Building on an introductory discussion of single-polymer statistical mechanics, the book provides a detailed treatment of analytical and numerical techniques for addressing the conformational properties of polymers subjected to spatially-varying potential fields. This problem is shown to be central to the field-theoretic description of interacting polymeric fluids, and models for a number of important polymer systems are elaborated. Chapter 5 serves to unify and expound the topic of self-consistent field theory, which is a collection of analytical and numerical techniques for obtaining solutions o...

Peer relations constitute a main developmental context for adolescents. Peers offer an instance for identity definition and set the norms of acceptable and valued characteristics, behaviors, and attitudes, representing a societal model that allows and restrains avenues for adolescents' socioemotional development. The present article departs from these considerations to review research on adolescents' peer relations in Latin America from a socioemotional perspective. First, approaches to adolescence are discussed, with a main focus on attachment and identity theories, based on a bioecological framework. Then, a review of research in Latin America on friendships, school climate, and intergroup relations is presented. The discussion addresses the tension between theories and evidence generated in developed societies and highlights the particularities of Latin American youth, stressing the need for collecting local data.

In his paper "Th\\'eories homotopiques des 2-cat\\'egories", Jonathan Chiche studies homotopy theories on 2-Cat, the category of small strict 2-categories, given by classes of weak equivalences which he calls basic localizers of 2-Cat. These basic localizers of 2-Cat are a 2-categorical generalization of the notion of a basic localizer introduced by Grothendieck in "Pursuing stacks". In this paper, we deduce from the results of Jonathan Chiche and results we have obtained with Georges Maltsinio...
Gravity as an internal Yang-Mills gauge field theory of the Poincaré group.
Hennig, Jörg; Nitsch, Jürgen
1981-10-01
In the framework of affine bundles we present gravity as an “internal” gauge field theory of the Poincaré group. The resulting geometry is a Riemann-Cartan space-time carrying torsion and curvature. In order to admit a nontrivial action of the translation group we formally extend the matter Lagrangian to affine field variables. Finally, we establish the relation of our approach with the formalism of Hehl et al.
Socio-cultural viability of international peacebuilding : An inquiry based on cultural theory
Sahovic, Dzenan
2007-01-01
A socio-anthropological theoretical framework of the so-called Grid-Group Cultural Theory provides a typological model for understanding and mapping of cultural biases (shared values and beliefs), corresponding social relations and strategic behaviours. The starting argument of this paper is that this model can be used to illuminate and investigate the socio-cultural differences in peacebuilding approaches as the four theoretical ideal-types of individualism, egalitarianism, hierarchy and fat...

This paper attempts to test the theory developed by Gray [1988] linking accounting values and systems with Hofstede’s [1980] cultural constructs. Based on data from twenty-nine countries, it finds that while Gray's [1988] model has statistically significant explanatory power, it is best at explaining actual financial reporting practices and is relatively weak in explaining extant professional and regulatory structures from a cultural base. This paper further finds that both the development of...
Functional categories in comparative linguistics
DEFF Research Database (Denmark)
Rijkhoff, Jan
Functional categories in comparative linguistics Even after many decades of typological research, the biggest methodological problem still concerns the fundamental question: how can we be sure that we identify and compare the same linguistic form, structure, meaning etc. across languages? Very few...... linguistic categories, if any, appear to be ‘universal’ in the sense that they are attested in each and every language (Evans and Levinson 2009). The language-specific nature of form-based (structural, morphosyntactic) categories is well known, which is why typologists usually resort to ‘Greenbergian......’, meaning-based categories. The use of meaning-based or semantic categories, however, does not necessarily result in the identification of cross-linguistically comparable data either, as was already shown by Greenberg (1966: 88) himself. Whereas formal categories are too narrow in that they do not cover all...
PREFACE: 6th International Conference on Inverse Problems in Engineering: Theory and Practice
Bonnet, Marc
2008-07-01
The 6th International Conference on Inverse Problems in Engineering: Theory and Practice (ICIPE 2008) belongs to a successful series of conferences held up to now following a three-year cycle. Previous conferences took place in Palm Coast, Florida, USA (1993), Le Croisic, France (1996), Port Ludlow, Washington, USA (1999), Angra dos Reis, Brazil (2002), and Cambridge, UK (2005). The conference has its roots on the informal seminars organized by Professor J V Beck at Michigan State University, which were initiated in 1987. The organization of this Conference, which took place in Dourdan (Paris) France, 15-19 June 2008, was made possible through a joint effort by four research departments from four different universities: LEMTA (Laboratoire de Mécanique Théorique et Appliquée, Nancy-Université) LMS (Laboratoire de Mécanique des Solides, Ecole Polytechnique, Paris) LMAC (Laboratoire de Mathématiques Appliquées, UTC Compiègne) LTN (Laboratoire de Thermocinétique, Université de Nantes) It received support from three organizations: SFT (Société Française de Thermique: French Heat Transfer Association) ACSM (Association Calcul de Structures et Simulation : Computational Structural Mechanics Association) GdR Ondes - CNRS (`Waves' Network, French National Center for Scientific Research) The objective of the conference was to provide the opportunity for interaction and cross-fertilization between designers of inverse methods and practitioners. The delegates came from very different fields, such as applied mathematics, heat transfer, solid mechanics, tomography.... Consequently the sessions were organised along mostly methodological topics in order to facilitate interaction among participants who might not meet otherwise. The present proceedings, published in the Journal of Physics: Conference Series, gathers the four plenary invited lectures and the full-length versions of 103 presentations. The latter have been reviewed by the scientific committee (see

The seamless transition from student to intern: from theory to practice.
Costello, J; Livett, M; Stride, P J O; West, M; Premaratne, M; Thacker, D
2010-10-01
Many publications have highlighted a lack of practical competencies in recently qualified interns. Consultation between the University of Queensland and the Medical Education Unit at Redcliffe Hospital identified key areas where intervention could lead to greater work readiness, and the development of a complementary programme of practical workshops to remedy those deficiencies. A variety of content experts introduced the Graduate Medical Course 3 and 4 students to a range of practical skills during a dedicated lunch time one hour workshop each week over a period of 30 weeks. Several sessions were audited by the trainers though the majority of sessions used self-evaluation by the participants. There was an overall self-reported increase in the ability to perform the tasks from 25% before the session to 90% afterwards. Seven of the participants are returning to the hospital as interns, and a follow-up survey will be performed to judge the usefulness of the programme. PMID:21038540

Further Test of Internal-conversion Theory with a Measurement in 119Sn
Nica, N.; Hardy, J. C.; Iacob, V. E.
2014-06-01
Precise measurements are being used to test theoretical K-shell internal conversion coefficients (ICCs): in particular, our program has focused on examining whether the atomic K-vacancy formed during the conversion process must be incorporated into the calculations. We report here a measurement on the 65.66-keV, M4 isomeric transition in 119Sn. Our preliminary result is αK = 1610 (27), which confirms the importance of including the vacancy in the ICC calculations.

In this paper, we develop a two-country model of monopolistic competition with quality differentiation by extending the model of Melitz and Ottaviano (2008) and examine the relationship between the bilateral trade structure and international technology spillovers. We show that bilateral trade patterns and the extent of technology spillovers will change, depending on the technology gap between two countries. We then test predictions of the model by using bilateral trade data among 44 countries...

Internal pressure buckling of very thin torispherical shells. A comparison of experiment and theory
International Nuclear Information System (INIS)
The bottom head of the primary vessel of some LMFBR's is a thin torispherical shell. The internal pressure loading on the head consists of the weight of the sodium contents plus any superimposed gas pressure. Depending on the design of the bottom head, it can fail by elastic or elastic-plastic circumferential buckling or the development of yield 'hinges' and gross deformation of the shell. A review is given of previous work on internal pressure buckling of torispheres - some of it of very recent origin. Experiments on a limited number of machined, stress-relieved, cylinder-torisphere combinations which were subjected to increasing internal pressure are described. The diameter-thickness ratios of the models were approximately 500 and 1000. It was also considered important to vary the ratio of the yield stress to the modulus of elasticity of the model material. This was accomplished by using both mild steel and an aluminium alloy for nominally identical models. The experimental buckling pressures are compared with the best available theoretical predictions

Theory of frustrated total internal reflection: Superluminal singularities of optical waveguides
International Nuclear Information System (INIS)
Classical approach to frustrated total internal reflection (FTIR) does not describe its temporal properties, that are additionally considered and their superluminal singularity is shown. The transition to quantum electrodynamics shows that momenta of photons are reduced at FTIR relative to energy, i.e. it is the tunnel process, the nonlocal manifestation of near field. The tunneling consists in the instantaneous jump of excitations (virtual photons) onto definite distance, and can be described by equation having certain instanton features. Thus, the possibility of signal transfer with superluminal group velocity via optical fibers is substantiated that conforms to certain supervisions. Such properties of FTIR near field may explain, in principle, some other observed phenomena

Full Text Available This paper attempts to contribute to ways by which confluence, referring to a meeting point for the different agents to cooperate and communicate on education policy processes, can be understood. Pertinent national education policies in countries receiving aid, in particular, are formed and implemented in a complex nexus. Cultural and context sensitivity can be stimulated through a thorough understanding of this confluence, which subsequently can enable the different policy agents, which function at this meeting point, collaborate to alleviate some of the educational challenges. Comparative and international education, in this respect, has a significant role to play.

Into the deep blue sea: Commons theory and international governance of Atlantic Bluefin Tuna
Directory of Open Access Journals (Sweden)
Graham Epstein
2014-08-01
Full Text Available The need to understand how to sustainably govern oceanic fisheries has become increasingly urgent as their contribution to global food security and livelihoods are threatened by declining stocks. Atlantic Bluefin Tuna (ABFT is a prominent example of the complexities associated with widely distributed oceanic resources, extending in this case to include much of the North-Atlantic and Mediterranean Sea. This distribution has led to limited attention from commons theorists that tend to focus on small-scale social ecological systems. Therefore in order to explore the fit between theories of the commons developed in small-scale systems, we apply the Social-Ecological Systems Meta-Analysis Database (SESMAD to systematically analyze ABFT governance over a 22 year period. The results, which focus on the effects of resource characteristics, broadly correspond to the expectations of commons theory. Interestingly, however, the addition of resource storage in the form of ABFT ranches appears to be contributing to unsustainable harvests. This stands in contrast to previous findings in the commons literature that storage tends to enhance prospects for sustainable governance. Therefore several alternative hypotheses are developed by comparing and contrasting attributes of ABFT and canal irrigation storage. These hypotheses may be used in future research to evaluate the conditions in which storage enhances prospects for sustainable governance.

An envelope in a category is a construction generalizing operations of "exterior completion", like completion of a locally convex space. Dually, an imprint generalizes operations of "interior enrichment", like saturation of a locally convex space. We give abstract definition for envelopes and imprints, prove existence of these objects in the categories of stereotype spaces and of stereotype algebras, and give some examples.

1996, Evans 2009). Furthermore certain ‘ontological categories’ are language-specific (Malt 1995).

In this talk I will discuss...... or construction in the process of verbal communication (in the tradition of the Prague School). I will argue that (a) functional categorization is methodologically prior to formal and semantic categorization (functional categories include semantic and formal categories) and (b) functional categories...... give better cross-linguistic ‘coverage’ then formal or semantic categories. Finally it will be shown that functional categories have their own distinct grammatical properties (Rijkhoff 2008, 2009b, forthcoming). References Bulmer, Ralph. 1967.

The neurobiology of category learning.
Ashby, F Gregory; Spiering, Brian J
2004-06-01
Many recent studies have examined the neural basis of category learning. Behavioral neuroscience results suggest that both the prefrontal cortex and the basal ganglia play important category-learning roles; neurons that develop category-specific firing properties are found in both regions, and lesions to both areas cause category-learning deficits. Similar studies indicate that the inferotemporal cortex does not mediate the learning of new categories. The cognitive neuroscience literature on category learning appears contradictory until the results are partitioned according to the type of category-learning task that was used. Three major tasks can be identified: rule based, information-integration, and prototype-distortion. Recent results are consistent with the hypotheses that (a) learning in rule-based tasks requires working memory and executive attention and is mediated by frontal-striatal circuits, (b) learning in information-integration tasks requires procedural memory and is mediated primarily within the basal ganglia, and (c) learning in prototype-distortion tasks depends on multiple memory systems, including the perceptual representation system.

Talker-specific influences on phonetic category structure.
Theodore, Rachel M; Myers, Emily B; Lomibao, Janice A
2015-08-01
A primary goal for models of speech perception is to describe how listeners achieve reliable comprehension given a lack of invariance between the acoustic signal and individual speech sounds. For example, individual talkers differ in how they implement phonetic properties of speech. Research suggests that listeners attain perceptual constancy by processing acoustic variation categorically while maintaining graded internal category structure. Moreover, listeners will use lexical information to modify category boundaries to learn to interpret a talker's ambiguous productions. The current work examines perceptual learning for talker differences that signal well-defined, unambiguous category members. Speech synthesis techniques were used to differentially manipulate talkers' characteristic productions of the stop voicing contrast for two groups of listeners. Following exposure to the talkers, internal category structure and category boundary were examined. The results showed that listeners dynamically adjusted internal category structure to be centered on experience with the talker's voice, but the category boundary remained fixed. These patterns were observed for words presented during training as well as novel lexical items. These findings point to input-driven constraints on functional plasticity within the language architecture, which may help to explain how listeners maintain stability of linguistic knowledge while simultaneously demonstrating flexibility for phonetic representations.

Category learning in the context of co-presented items.
Andrews, Janet K; Livingston, Kenneth R; Kurtz, Kenneth J
2011-05-01
A series of four studies explore how the presentation of multiple items on each trial of a categorization task affects the course of category learning. In a three-category supervised classification task involving multi-dimensionally varying artificial organism-like stimuli, learners are shown a target plus two context items on every trial, with the context items' category membership explicitly identified. These triads vary in whether one, two, or all three categories are represented. This presentation context can support within-category comparison and/or between-category contrast. The most successful learning occurs when all categories are represented in each trial. This pattern occurs across two different underlying category structures and across variations in learners' prior knowledge of the relationship between the target and context items. These results appear to contrast with some other recent findings and make clear the potential importance of context-based inter-item evaluation in human category learning, which has implications for psychological theory and for real-world learning environments.

The vacuum ultraviolet (VUV) photoionization and dissociative photoionization of three hydroxy-substituted [2.2]paracyclophane derivatives were studied yielding adiabatic ionization energies and dissociative photoionization energies (appearance energies). The simplest dissociation pathway is the breaking of both CH(2)-CH(2) bridge units and fragmenting the molecular ion in half to yield xylylene neutral and cationic fragments. The experimental data show that this process is outcompeted by a faster, higher energy channel, possibly yielding cyclooctatetraene derivatives. The role of the reaction coordinate, the effect of large amplitude motions on the density of states function at low and high energies and the temperature dependent 'population gap' in the internal energy distribution in large molecules are discussed in the context of applying statistical models to the dissociation. Computational approaches to the binding energy of paracyclophanes are marred with pitfalls. Noncovalent interactions play a major role in keeping paracyclophanes bound by some 200 kJ mol(-1) with respect to the two xylylene motifs, and the covalent CH(2)-CH(2) bonds are mostly counteracted by the geometric strain. The stabilizing effects are twofold: first, paracyclophanes are aromatic compounds, whereas xylylenes are not. Thus, the aromaticity of the molecule is induced by dimerization. Second, dispersive π-π interactions also stabilize the molecule. We evaluated 23 different computational chemistry approaches, and found that very few of the favorably scaling ones give an adequate description of this system. Among the DFT functionals tested, only PBE-D3 and perhaps M06-2X yielded consistently accurate results, comparable with MP3 and CCSD, or the G4 and CBS-QB3 composite methods. MP2 results in general suffer from significant overbonding. PMID:22847148

Full Text Available Abdulrahman Saud Al-rasheed Department of Psychology, King Saud University, Riyadh, Kingdom of Saudi Arabia Abstract: Despite a plethora of behavioral research exploring the phenomenon of color categorical perception (CP known as "better discrimination between pair of colors stimuli from different categories and pair of colors stimuli from the same category even when the stimulus differences between the pairs of stimuli are equal", most of the evidence for the CP of color was derived from Roman or top-to-down script readers and very rarely from right-to-left script readers in primary category. To date, no studies of color CP have been conducted on right-to-left script readers in secondary category boundary to support this theory. Three experiments have been conducted: Experiments 1 and 2 established the Arabic blue–purple secondary category boundary, and Experiment 3 tested the CP of color in the blue–purple category boundary. Sixty participants (30 men and 30 women took part in this study. All spoke Arabic as their first language, and all were undergraduate or postgraduate students at King Saud University. Their ages ranged from 18–35 years with a mean age of 21.9 years (SD =5.2. The result indicated that for Experiments 1 and 2, it appeared that the Arabic blue–purple category boundary was approximately 10PB and it is in the same location as for English. For Experiment 3, reaction times in the between-categories condition were significantly faster than those in the within-category condition; this suggested that CP of color was shown in the Arabic's blue–purple secondary category boundary. Keywords: categorical perception, CP of color, categorization, blue–purple category boundary, secondary category boundary
'Protestantism' as a historical category.
Ryrie, Alec
2016-01-01
The term ‘Protestant’ itself is a historical accident, but the category of western Christians who have separated from Rome since 1517 remains a useful one. The confessionalisation thesis, which has dominated recent Reformation historiography, instead posits the two major Protestant confessions and Tridentine Catholicism as its categories, but this can produce a false parallelism in which the nature of relationship between the confessions is oversimplified. Instead, this paper proposes we thin...

This study used an electrophysiological marker of visual detection to investigate adults' processing of colour difference. Event-related potentials were collected from the identical colour (green: G0) presented as the frequent or infrequent stimulus within different colour contexts. Critically, we compared differences within the same colour category (G0 vs. green: G1) to differences between colour categories (G0 vs. blue and G0 vs. red). All differences showed a change-related positivity with...
Cluster categories and cluster-tilted algebras
Torkildsen, Hermund Andre
2006-01-01
We have given an introduction to the theory of cluster categories and cluster-tilted algebras, and this was one of our main objectives in this thesis. We have seen that cluster-tilted algebras are relation-extension algebras, and this gave us a way of constructing the quiver of a cluster-tilted algebra from a tilted algebra. A cluster-tilted algebra of finite representation type is determined by its quiver, and this raised questions about the generality of this result. We defined a new class...

Instead of studying anyon condensation in various concrete models, we take a bootstrap approach by considering an abstract situation, in which an anyon condensation happens in a 2-d topological phase with anyonic excitations given by a modular tensor category C; and the anyons in the condensed phase are given by another modular tensor category D. By a bootstrap analysis, we derive a relation between anyons in D-phase and anyons in C-phase from natural physical requirements. It turns out that the vacuum (or the tensor unit) A in D-phase is necessary to be a connected commutative separable algebra in C, and the category D is equivalent to the category of local A-modules as modular tensor categories. This condensation also produces a gapped domain wall with wall excitations given by the category of A-modules in C. A more general situation is also studied in this paper. We will also show how to determine such algebra A from the initial and final data. Multi-condensations and 1-d condensations will also be briefly discussed. Examples will be given in the toric code model, Kitaev quantum double models, Levin–Wen types of lattice models and some chiral topological phases.

In this paper, we describe a Mackey type decomposition for group actions on abelian categories. This allows us to define new Mackey functors which associates to any subgroup the K-theory of the corresponding equivariantized abelian category. In the case of an action by tensor autoequivalences, the Mackey functor at the level of Grothendieck rings has a Green functor structure. As an application we give a description of the Grothendieck rings of equivariantized fusion categories under group actions by tensor autoequivalences on graded fusion categories. In this settings, a new formula for the tensor product of any two simple objects of an equivariantized fusion category is given, simplifying the fusion formula from Burciu and Natale [J. Math. Phys. 54, 013511 (2013)].

We study the ring homomorphism HH^*(kC) ---> H^*(|C|,k) and prove it is split surjective, using the factorization category of Quillen and certain techniques from functor cohomology theory. This generalizes the well-known theorems for groups and posets. Based on this result, we construct a seven-dimensional cate...

In this article we construct a category ζ(R) whose objects are real functions with any domain in ζ (category of sets) and whose morphisms are the set functions in ζ which satisfy a certain condition. We study some properties of ζ(R) with the help of a functor K:ζ(R)→ζ and obtain that it is complete and co-complete in the finite sense. The notation and basic concepts of category theory used in this article are all well known. 5 refs

Incremental Interpretation of Categorial Grammar
Milward, D
1995-01-01
The paper describes a parser for Categorial Grammar which provides fully word by word incremental interpretation. The parser does not require fragments of sentences to form constituents, and thereby avoids problems of spurious ambiguity. The paper includes a brief discussion of the relationship between basic Categorial Grammar and other formalisms such as HPSG, Dependency Grammar and the Lambek Calculus. It also includes a discussion of some of the issues which arise when parsing lexicalised grammars, and the possibilities for using statistical techniques for tuning to particular languages.

In this paper, the multiconfigurational time-dependent Hartree for bosons (MCTDHB) method is derived for the case of N identical bosons with internal degrees of freedom. The theory for bosons with internal degrees of freedom constitutes a generalization of the MCTDHB method that substantially enriches the many-body physics that can be described. We demonstrate that the numerically exact solution of the time-dependent many-body Schrödinger equation for interacting bosonic particles with internal degrees of freedom is now feasible. We report on the MCTDHB equations of motion for bosons with internal degrees of freedom and their implementation for a general many-body Hamiltonian with one-body and two-body terms, both of which may depend on the internal states of the considered particles and time. To demonstrate the capabilities of the theory and its software implementation integrated in the mctdh-x software, we apply MCTDHB to the emergence of fragmentation of parabolically trapped bosons with two internal states: we study the ground state of N =100 bosons as a function of the separation between the state-dependent minima of the two parabolic potentials. To quantify the coherence of the system, we compute its normalized first-order correlation function. We find that the coherence within each internal state of the atoms is maintained, while it is lost between the different internal states. This is a hallmark of a kind of fragmentation absent in bosons without internal structure. We term the emergent phenomenon "composite fragmentation."
A Bayesian model of category-specific emotional brain responses.

2015-04-01
Understanding emotion is critical for a science of healthy and disordered brain function, but the neurophysiological basis of emotional experience is still poorly understood. We analyzed human brain activity patterns from 148 studies of emotion categories (2159 total participants) using a novel hierarchical Bayesian model. The model allowed us to classify which of five categories--fear, anger, disgust, sadness, or happiness--is engaged by a study with 66% accuracy (43-86% across categories). Analyses of the activity patterns encoded in the model revealed that each emotion category is associated with unique, prototypical patterns of activity across multiple brain systems including the cortex, thalamus, amygdala, and other structures. The results indicate that emotion categories are not contained within any one region or system, but are represented as configurations across multiple brain networks. The model provides a precise summary of the prototypical patterns for each emotion category, and demonstrates that a sufficient characterization of emotion categories relies on (a) differential patterns of involvement in neocortical systems that differ between humans and other species, and (b) distinctive patterns of cortical-subcortical interactions. Thus, these findings are incompatible with several contemporary theories of emotion, including those that emphasize emotion-dedicated brain systems and those that propose emotion is localized primarily in subcortical activity. They are consistent with componential and constructionist views, which propose that emotions are differentiated by a combination of perceptual, mnemonic, prospective, and motivational elements. Such brain-based models of emotion provide a foundation for new translational and clinical approaches. PMID:25853490

Fukaya categories of the torus and Dehn surgery

2011-01-01
This paper is a companion to the authors' forthcoming work extending Heegaard Floer theory from closed 3-manifolds to compact 3-manifolds with two boundary components via quilted Floer cohomology. We describe the first interesting case of this theory: the invariants of 3-manifolds bounding S^2 union T^2, regarded as modules over the Fukaya category of the punctured 2-torus. We extract a short proof of exactness of the Dehn surgery triangle in Heegaard Floer homology. We show that A_\\infty-structures on the graded algebra A formed by the cohomology of two basic objects in the Fukaya category of the punctured 2-torus are governed by just two parameters (m^6,m^8), extracted from the Hochschild cohomology of A. For the Fukaya category itself, m^6 is nonzero.

Cluster algebras and derived categories
Keller, Bernhard
2012-01-01
This is an introductory survey on cluster algebras and their (additive) categorification using derived categories of Ginzburg algebras. After a gentle introduction to cluster combinatorics, we review important examples of coordinate rings admitting a cluster algebra structure. We then present the general definition of a cluster algebra and describe the interplay between cluster variables, coefficients, c-vectors and g-vectors. We show how c-vectors appear in the study of quantum cluster algebras and their links to the quantum dilogarithm. We then present the framework of additive categorification of cluster algebras based on the notion of quiver with potential and on the derived category of the associated Ginzburg algebra. We show how the combinatorics introduced previously lift to the categorical level and how this leads to proofs, for cluster algebras associated with quivers, of some of Fomin-Zelevinsky's fundamental conjectures.

International entrepreneurship, a burgeoning social science, is receiving more and more scholars＇ attention and interest. The complexity of the research object and the diversity of methodology make it gradually evolved into a comprehensive and cross discipline. The development of the theory of international entrepreneurship can be classified into three stages： the dominant of international business, the intersection of the theory of international business and entrepreneurship and the muhidisciplinary stage. Furthermore, three representative international entrepreneurship models outline a more clearly development path of international entrepreneurship. There are also some defects of the development of international entrepreneurship. The empirical studies in general for small business, the theory of international business and entrepreneurship failed to combine well and the unscientific methods of empirical research. Finally, the effectuation logic theory provides a new perspective for international entrepreneurship.%国际创业作为一门新兴社会科学理论，受到越来越多学者的关注和研究，其研究对象的复杂性以及研究方法的多样性使其逐渐演变成一门综合性交叉性学科。国际创业理论经历了国际商务理论主导阶段、国际商务和创业理论交汇阶段和多学科交叉阶段。国际创业模型演进中主要出现了四个具有代表性的模型。当前国际企业研究还存在实证研究普遍以小企业为研究对象、国际商务和创业理论未能有机交汇、实证研究方法不科学等缺陷。效果逻辑理论为国际创业研究提供了新视角。

Completeness of †-categories and the complex numbers
International Nuclear Information System (INIS)
The complex numbers are an important part of quantum theory, but are difficult to motivate from a theoretical perspective. We describe a simple formal framework for theories of physics, and show that if a theory of physics presented in this manner satisfies certain completeness properties, then it necessarily includes the complex numbers as a mathematical ingredient. Central to our approach are the techniques of category theory, and we introduce a new category-theoretical tool, called the †-limit, which governs the way in which systems can be combined to form larger systems. These †-limits can be used to characterize the properties of the †-functor on the category of finite-dimensional Hilbert spaces, and so can be used as an equivalent definition of the inner product. One of our main results is that in a nontrivial monoidal †-category with finite †-limits and a simple tensor unit, the semiring of scalars embeds into an involutive field of characteristic 0 and orderable fixed field.

A Category Theoretic Model of RDF Ontology
Directory of Open Access Journals (Sweden)
S. Aliyu
2015-07-01
Full Text Available Ontology languages are used in modelling the semantics of concepts within a particular domain and the relationships between those concepts. The Semantic Web standard provides a number of modelling languages that differ in their level of expressivity and are organized in a Semantic Web Stack in such a way that each language level builds on the expressivity of the other. There are several problems when one attempts to use independently developed ontologies. When existing ontologies are adapted for new purposes it requires that certain operations are performed on them. These operations are currently performed in a semi-automated manner. This paper seeks to model categorically the syntax and semantics of RDF ontology as a step towards the formalization of ontological operations using category theory.
Regular Functors and Relative Realizability Categories
Stekelenburg, Wouter Pieter
2011-01-01
Relative realizability toposes satisfy a universal property that involves regular functors to other categories. We use this universal property to define what relative realizability categories are, when based on other categories than of the topos of sets. This paper explains the property and gives a construction for relative realizability categories that works for arbitrary base Heyting categories. The universal property shows us some new geometric morphisms to relative realizability toposes too.

National policymakers are currently considering a dilemma of critical importance to the continued security of the United States: how can U.S. nuclear weapons policies be leveraged to benefit U.S. nuclear nonproliferation goals in the near-term, without sacrificing U.S. national security?

National policymakers are currently considering a dilemma of critical importance to the continued security of the United States: how can U.S. nuclear weapons policies be leveraged to benefit U.S. nuclear nonproliferation goals in the near-term, without sacrificing U.S. national security? In its role supporting U.S. nuclear weapons policy, Sandia National Laboratories has a responsibility to provide objective technical advice to support policy deliberations on this question. However, to best fulfill this duty Sandia must have a broader understanding of the context of the problem. To help develop this understanding, this paper analyzes the two predominant analytical perspectives of international relations theory to explore their prescriptions for how nuclear weapons and nonproliferation policies interact.

Pattern-Induced Covert Category Learning in Songbirds.
Comins, Jordan A; Gentner, Timothy Q
2015-07-20
Language is uniquely human, but its acquisition may involve cognitive capacities shared with other species. During development, language experience alters speech sound (phoneme) categorization. Newborn infants distinguish the phonemes in all languages but by 10 months show adult-like greater sensitivity to native language phonemic contrasts than non-native contrasts. Distributional theories account for phonetic learning by positing that infants infer category boundaries from modal distributions of speech sounds along acoustic continua. For example, tokens of the sounds /b/ and /p/ cluster around different mean voice onset times. To disambiguate overlapping distributions, contextual theories propose that phonetic category learning is informed by higher-level patterns (e.g., words) in which phonemes normally occur. For example, the vowel sounds /Ι/ and /e/ can occupy similar perceptual spaces but can be distinguished in the context of "with" and "well." Both distributional and contextual cues appear to function in speech acquisition. Non-human species also benefit from distributional cues for category learning, but whether category learning benefits from contextual information in non-human animals is unknown. The use of higher-level patterns to guide lower-level category learning may reflect uniquely human capacities tied to language acquisition or more general learning abilities reflecting shared neurobiological mechanisms. Using songbirds, European starlings, we show that higher-level pattern learning covertly enhances categorization of the natural communication sounds. This observation mirrors the support for contextual theories of phonemic category learning in humans and demonstrates a general form of learning not unique to humans or language. PMID:26119748

Full Text Available The article argues that internal colonization should be analyzed from a transnational perspective, as a shared repertoire of ideas and practices that can be observed in the interwar period. First, it critically discusses the use of ‘internal colonization’ and ‘internal colonialism’ as historical and analytical concepts. It then links these to recent debates in historiography about the ‘colonial’ nature of continental empires and the distinct place and importance ascribed to internal colonization within these debates. The last part presents the variety of rationales underpinning resettlement schemes and shows how these were articulated in the various programmes and practices of internal colonization analyzed in this theme issue.
Lexically guided retuning of visual phonetic categories.
van der Zande, Patrick; Jesse, Alexandra; Cutler, Anne
2013-07-01
Listeners retune the boundaries between phonetic categories to adjust to individual speakers' productions. Lexical information, for example, indicates what an unusual sound is supposed to be, and boundary retuning then enables the speaker's sound to be included in the appropriate auditory phonetic category. In this study, it was investigated whether lexical knowledge that is known to guide the retuning of auditory phonetic categories, can also retune visual phonetic categories. In Experiment 1, exposure to a visual idiosyncrasy in ambiguous audiovisually presented target words in a lexical decision task indeed resulted in retuning of the visual category boundary based on the disambiguating lexical context. In Experiment 2 it was tested whether lexical information retunes visual categories directly, or indirectly through the generalization from retuned auditory phonetic categories. Here, participants were exposed to auditory-only versions of the same ambiguous target words as in Experiment 1. Auditory phonetic categories were retuned by lexical knowledge, but no shifts were observed for the visual phonetic categories. Lexical knowledge can therefore guide retuning of visual phonetic categories, but lexically guided retuning of auditory phonetic categories is not generalized to visual categories. Rather, listeners adjust auditory and visual phonetic categories to talker idiosyncrasies separately. PMID:23862831
Seismic Category I Structures Program
International Nuclear Information System (INIS)
With the use of different size scale models, the Seismic Category I Structures Program has demonstrated consistent results for measured values of stiffness at working loads. Furthermore, the values are well below the theoretical stiffnesses calculated from an uncracked strength-of-materials approach. The scale model structures, which are also models of each other, have demonstrated scalability between models. The current effort is to demonstrate that the use of microconcrete and other modeling effects do not introduce significant distortions that could drastically change conclusions regarding prototype behavior for these very stiff, shear-dominated structures. Working closely with the technical review group (TRG) for this program, structures have been designed and tests have been planned that will help to resolve issues surrounding the use of microconcrete scale models
Standardization of radioactive waste categories
International Nuclear Information System (INIS)
A large amount of information about most aspects of radioactive waste management has been accumulated and made available to interested nations in recent years. The efficiency of this service has been somewhat hampered because the terminology used to describe the different types of radioactive waste has varied from country to country and indeed from installation to installation within a given country. This publication is the outcome of a panel meeting on Standardization of Radioactive Waste Categories. It presents a simple standard to be used as a common language between people working in the field of waste management at nuclear installations. The purpose of the standard is only to act as a practical tool for increasing efficiency in communicating, collecting and assessing technical and economical information in the common interest of all nations and the developing countries in particular. 20 refs, 1 fig., 3 tabs

This monograph on the homotopy theory of topologized diagrams of spaces and spectra gives an expert account of a subject at the foundation of motivic homotopy theory and the theory of topological modular forms in stable homotopy theory. Beginning with an introduction to the homotopy theory of simplicial sets and topos theory, the book covers core topics such as the unstable homotopy theory of simplicial presheaves and sheaves, localized theories, cocycles, descent theory, non-abelian cohomology, stacks, and local stable homotopy theory. A detailed treatment of the formalism of the subject is interwoven with explanations of the motivation, development, and nuances of ideas and results. The coherence of the abstract theory is elucidated through the use of widely applicable tools, such as Barr's theorem on Boolean localization, model structures on the category of simplicial presheaves on a site, and cocycle categories. A wealth of concrete examples convey the vitality and importance of the subject in topology, n...
Locally finitely presented categories and functor rings

By using the correspondence between locally finitely presented additive categories and rings with enough idempotents, we study several properties of such rings in terms of the associated categories, and conversely. In particular, it is shown that a ring $R$ (with enough idempotents) is right perfect and the categories of finitely presented right and left $R$-modules are dual to each other if and only if the categories of projective and of injective right $R$-modules are equi...

A Compositional Treatment of Polysemous Arguments in Categorial Grammar
Mineur, A M; Mineur, Anne-Marie; Buitelaar, Paul
1995-01-01
We discuss an extension of the standard logical rules (functional application and abstraction) in Categorial Grammar (CG), in order to deal with some specific cases of polysemy. We borrow from Generative Lexicon theory which proposes the mechanism of {\\em coercion}, next to a rich nominal lexical semantic structure called {\\em qualia structure}. In a previous paper we introduced coercion into the framework of {\\em sign-based} Categorial Grammar and investigated its impact on traditional Fregean compositionality. In this paper we will elaborate on this idea, mostly working towards the introduction of a new semantic dimension. Where in current versions of sign-based Categorial Grammar only two representations are derived: a prosodic one (form) and a logical one (modelling), here we introduce also a more detaled representation of the lexical semantics. This extra knowledge will serve to account for linguistic phenomena like {\\em metonymy\\/}.

Precise values for internal conversion coefficients (ICCs) are important in the study of nuclear decay schemes; they are also useful for detector efficiency calibration. A recent survey revealed that few measured ICCs are known to a high precision (˜ 1%); in addition, there is some theoretical uncertainty over how to deal with the atomic vacancy left by the departing electron during the internal conversion process. Texas A&M has previously precisely measured the ICCs for ^193Ir, ^137Ba, and ^134Cs as a test of internal conversion theory; we now consider the ICC for ^197Pt^m as a further test. The ^197Pt^m was produced by thermal neutron activation of separated ^196Pt (97.43% pure). Two separate sources were produced; x-ray and gamma-ray emissions from each source were recorded by a High Purity Germanium Detector (+/- 0.20% absolute efficiency uncertainty). After impurity subtraction and attenuation correction, preliminary results for the αk value for the two sources have now been obtained. The αk from source one is 4.24 (13); the αk from source two is 4.26 (8). While these values are still tentative, the results show agreement with the theory that considers the atomic vacancy.
The balanced tensor product of module categories

The balanced tensor product M (x)_A N of two modules over an algebra A is the vector space corepresenting A-balanced bilinear maps out of the product M x N. The balanced tensor product M [x]_C N of two module categories over a monoidal linear category C is the linear category corepresenting C-balanced right-exact bilinear functors out of the product category M x N. We show that the balanced tensor product can be realized as a category of bimodule objects in C, provided the monoidal linear cat...

Full Text Available Previously we found that Parkinson's disease (PD patients are impaired in procedural-based category learning when category membership is defined by a nonlinear relationship between stimulus dimensions, but these same patients are normal when the rule is defined by a linear relationship (Filoteo et al., 2005; Maddox & Filoteo, 2001. We suggested that PD patients' impairment was due to a deficit in recruiting ‘striatal units' to represent complex nonlinear rules. In the present study, we further examined the nature of PD patients' procedural-based deficit in two experiments designed to examine the impact of (1 the number of categories, and (2 category discontinuity on learning. Results indicated that PD patients were impaired only under discontinuous category conditions but were normal when the number of categories was increased from two to four. The lack of impairment in the four-category condition suggests normal integrity of striatal medium spiny cells involved in procedural-based category learning. In contrast, and consistent with our previous observation of a nonlinear deficit, the finding that PD patients were impaired in the discontinuous condition suggests that these patients are impaired when they have to associate perceptually distinct exemplars with the same category. Theoretically, this deficit might be related to dysfunctional communication among medium spiny neurons within the striatum, particularly given that these are cholinergic neurons and a cholinergic deficiency could underlie some of PD patients’ cognitive impairment.

Generalizing the O(N)-field theory to N-colored manifolds of arbitrary internal dimension D
International Nuclear Information System (INIS)
We introduce a geometric generalization of the O(N)-field theory that describes N-colored membranes with arbitrary dimension D. As the O(N)-model reduces in the limit N→0 to self-avoiding polymers, the N-colored manifold model leads to self-avoiding tethered membranes. In the other limit, for inner dimension D→1, the manifold model reduces to the O(N)-field theory. We analyze the scaling properties of the model at criticality by a one-loop perturbative renormalization group analysis around an upper critical line. The freedom to optimize with respect to the expansion point on this line allows us to obtain the exponent ν of standard field theory to much better precision that the usual 1-loop calculations. Some other field theoretical techniques, such as the large N limit and Hartree approximation, can also be applied to this model. By comparison of low- and high-temperature expansions, we arrive at a conjecture for the nature of droplets dominating the 3d Ising model at criticality, which is satisfied by our numerical results. We can also construct an appropriate generalization that describes cubic anisotropy, by adding an interaction between manifolds of the same color. The two parameter space includes a variety of new phases and fixed points, some with Ising criticality, enabling us to extract a remarkably precise value of 0.6315 for the exponent ν in d=3. A particular limit of the model with cubic anisotropy corresponds to the random bond Ising problem; unlike the field theory formulation, we find a fixed point describing this system at 1-loop order.

We evaluate two competing accounts of the relationship between beauty and category structure. According to the similarity-based view, beauty arises from category structure such that central items are favored due to their increased fluency. In contrast, the theory-based view holds that people's theories of beauty shape their perceptions of categories. In the present study, subjects learned to categorize abstract paintings into meaningfully labeled categories and rated the paintings' beauty, value, and typicality. Inconsistent with the similarity-based view, beauty ratings were highly correlated across conditions despite differences in fluency and assigned category structure. Consistent with the theory-based view, beautiful paintings were treated as central members for categories expected to contain beautiful paintings (e.g., art museum pieces), but not in others (e.g., student show pieces). These results suggest that the beauty of complex, real-world stimuli is not determined by fluency within category structure but, instead, interacts with people's prior knowledge to structure categories.

1999-01-01
Although price promotions have increased in both commercial use and quantity of academic research over the last decade, most of the attention has been focused on their effects on brand choice and brand sales. By contrast, little is known about the conditions under which price promotions expand short-run and long-run category demand, even though the benefits of category expansion can be substantial to manufacturers and retailers alike. This paper studies the category-demand effects of consumer...

Design Theory in Information Systems
Shirley Gregor
2002-01-01
The aim of this paper is to explore an important category of information systems knowledge that is termed “design theory”. This knowledge is distinguished as the fifth of five types of theory: (i) theory for analysing and describing, (ii) theory for understanding, (iii) theory for predicting, (iv) theory for explaining and predicting, and (v) theory for design and action. Examples of design theory in information systems are provided, with associated research methods. The limited understanding...

Full Text Available In the present paper we will apply the Predictive And Reactive Control Systems (PARCS theory as a framework that integrates competing theories of neural substrates of awareness by describing the default mode network (DMN and anterior insula (AI as parts of two different behavioral and homeostatic control systems. The DMN, a network that becomes active at rest when there is no external stimulation or task to perform, has been implicated in self-reflective awareness and prospection. By contrast, the AI is associated with awareness and task-related attention. This has led to competing theories stressing the role of the DMN in self-awareness versus the role of interoceptive and emotional information integration in the AI in awareness of the emotional moment. In PARCS, the respective functions of the DMN and AI in a specific control system explains their association with different qualities of awareness, and how mental states can shift from one state (e.g., prospective self-reflection to the other (e.g., awareness of the emotional moment depending on the relative dominance of control systems. These shifts between reactive and predictive control are part of processes that enable the intake of novel information, integration of this novel information within existing knowledge structures, and the creation of a continuous personal context in which novel information can be integrated and understood. As such, PARCS can explain key characteristics of mental states, such as their temporal and spatial focus (e.g., a focus on the here and now vs. the future; a 1st person vs. a 3rd person perspective. PARCS further relates mental states to brain states and functions, such as activation of the DMN or hemispheric asymmetry in frontal cortical functions. Together, PARCS deepens the understanding of a broad range of mental states, including mindfulness, mind wandering, rumination, autobiographical memory, imagery, and the experience of self.

That ‘constructivist turn’ characterized International Relations theory in the 1990s was due to, on the one hand, the resurgence in international politics of such ideational and societal factors as identity, culture, and norms with the end of the Cold War and their incresing importance in the study of international relations, and on the other hand, the opening up space in the discipline in which new approaches can be entertained thanks to profound critics against mainstream approaches.

Rob Goldston (PPPL) kicked off the Sherwood meeting with his review talk, “Understanding and innovation in magnetic fusion”. He covered a history of results from tokamak experiments in the areas of core confinement, stability, sustainment – tying the paradigms for understanding all three to the plasma edge, where outstanding questions remain. Two other review talks were given by Russel Caflisch (UCLA) on “Accelerated simulation of coulomb collisions in plasmas”, and Dan Barnes (Tri Alpha) on “Plasma theory as private enterprise”. Altogether, there were 15 invited talks spanning the field of fusion theory on topics such as nonlinear gyrokinetic simulations of the tokamak edge, plasma-wall modelling, toroidal rotation, zonal flows, magnetic field-line reconnection, coulomb collisions, and intrinsic momentum transport. Author-provided summaries of several of the invited talks are included on pages 7 to 14 of this document. There was a very strong showing by graduate students, postdocs, and young scientists at the meeting. More than 25 students from around the world presented papers.

Monoidal category of operad of graphs
Rodriguez, Maria Ernestina Chavez
2011-01-01
Usually a name of the category is inherited from the name of objects. However more relevant for a category of objects and morphisms is an algebra of morphisms. Therefore we prefer to say a category of graphs if every morphism is a graph. In a monoidal category every morphism can be seen as a graph, and a partial algebra of morphisms possesses a structure of an operad, operad of graphs. We consider a monoidal category of operad of graphs with underlying graphical calculus. If, in particular, there is a single generating objects, then each morphism is a bi-arity graph. The graphical calculus, multi-grafting of morphisms, is developed ab ovo. We interpret algebraic logic and predicate calculus within a monoidal category of operad of graphs, and this leads to the graphical logic. A logic based on a braided monoidal category is said to be the braided logic. We consider a braided monoidal category generated by one object. We are demonstrating how the braided logic is related to implicative algebra and to the Heytin...

Diagnostic Categories in Autobiographical Accounts of Illness.
Kelly, Michael P
2015-01-01
Working within frameworks drawn from the writings of Immanuel Kant, Alfred Schutz, and Kenneth Burke, this article examines the role that diagnostic categories play in autobiographical accounts of illness, with a special focus on chronic disease. Four lay diagnostic categories, each with different connections to formal medical diagnostic categories, serve as typifications to make sense of the way the lifeworld changes over the course of chronic illness. These diagnostic categories are used in conjunction with another set of typifications: lay epidemiologies, lay etiologies, lay prognostics, and lay therapeutics. Together these serve to construct and reconstruct the self at the center of the lifeworld. Embedded within the lay diagnostic categories are narratives of progression, regression, or stability, forms of typification derived from literary and storytelling genres. These narratives are developed by the self in autobiographical accounts of illness. PMID:26657684

Categories by Heart: Shortcut Reasoning in a Cardiology Clinic
Directory of Open Access Journals (Sweden)
Katarina Jacobsson
2014-09-01
Full Text Available This article examines the practice of doctors and nurses to invoke the categories of age, sex, class, ethnicity, and/or lifestyle factors when discussing individual patients and patient groups. In what situations are such references explicitly made, and what does this practice accomplish? The material consists of field notes from a cardiology clinic in Sweden, and a theory of descriptive practice guided the analysis. When professionals describe patients, discuss decisions, or explain why a patient is ill, age, sex, class, ethnicity, and/or lifestyle serve as contextualization cues, often including widespread results from epidemiological research about groups of patients at higher or lower risk for cardiac disease. These categories work as shortcut reasoning to nudge interpretations in a certain direction, legitimize decisions, and strengthen arguments. In general, studying the descriptions of patients/clients/students provides an entrance to professional methods of reasoning, including their implicit moral assumptions.

In this study, nonlinear vibration and stability of a fluid-conveying nanotube (FCNT), elastically coupled to a smart piezoelectric polymeric beam (PPB) is investigated based on nonlocal elasticity theory, Euler–Bernoulli beam model and energy approach. In order to obtain an active instability control of FCNT, the PPB is longitudinally polarized as an actuator while in the absence of an imposed electric field it is also possible to be used as an alarm biosensor. Simulating the above smart coupled nanobeam system alike the double nanobeam systems (which are relatively developed by other authors) leads to obtain nonlinear differential equations of motion. The linear natural and damping frequencies are achieved by ignoring all the system nonlinearities which are then considered to obtain nonlinear frequencies using an iterative method. The effects of geometric nonlinearity, small scale parameter, coupled medium constants, Knudsen number, temperature change, aspect ratio and external applied voltage on critical flow velocity are studied in details. It is concluded that applying an electric voltage on PPB will increase the stability of FCNT. It is hoped that this research will provide a new approach to smart instability control of FCNTs which is no yet reported

TRIPS 與羅爾斯的國際正義理論初探 The TRIPS Agreement and John Rawls’s Theory of International Justice

Full Text Available 本文探討政治哲學家約翰〃羅爾斯（John Rawls）於1990 年代後期發展的國際正義理論如何適用於對「與貿易有關的智財權協定」（TRIPS）的訂定背景的分析，目的是在建立一個對於TRIPS 加以批判的觀點。羅爾斯的國際正義理論主要發展於他的「人民間法」（The Law of Peoples）一書，但與羅爾斯以前的著作，包括「正義論」（A Theory of Justice）與「政治自由主義」（Political Liberalism）有脈絡上密不可分的關係。本文詴圖應用在這些著作中提出的概念，包括第二（國際）原始立場、無知面紗、暫時狀態與重疊共識的區別等。在另一面，TRIPS 的訂立過程呈現的問題，如貿易與智財權的連結、對於國際智財權體制的功能的基本不合意、對開發中國家的不帄衡負擔等，都是「政治自由主義」所要解釋的問題，也就是基於暫時協定的體制，如何能克服穩定性上的困難，而達成重疊共識的目標。本文係針對此問題所提出的初步的看法。 The topic of this article is how the theory of international justice developed by political philosopher John Rawls in the mid-1990s can be applied to analyzing TRIPS, the Agreement on Trade-Related Aspects of Intellectual Property Rights, and its drafting process. The purpose here is to construct a point of view for the critique of TRIPS. Rawls’s theory of international justice was primarily developed in his The Law of Peoples but also bore imprints from the previous works, including A Theory of Justice and Political Liberalism. The author of this article has intended to apply several concepts proposed by Rawls in these works, including the second stage of the original position, the veil of ignorance, modus vivendi, and overlapping consensus. Many issues relating to TRIPS’ drafting process are in effect the questions that Political Liberalism has intended to answer; these

2012-01-01
We determine the fusion rules of the equivariantization of a fusion category $\\mathcal{C}$ under the action of a finite group $G$ in terms of the fusion rules of $\\mathcal{C}$ and group-theoretical data associated to the group action. As an application we obtain a formula for the fusion rules in an equivariantization of a pointed fusion category in terms of group-theoretical data. This entails a description of the fusion rules in any braided group-theoretical fusion category.

The first part develops a theory of distortions of competition among competing firms, induced by differences in the method and/or stringency of national allocation of greenhouse gas emission permits in an international emissions trading system. By applying neoclassical theory on output optimisation, price setting and other factors such as R and D expenditures, five potentially distorting effects are identified for perfect and imperfect markets,. The second part develops economic indicators and a two tier approach, which can be applied empirically, in order to test whether an industry is vulnerable to the potential effects found before. The third part applies the two tier approach empirically to four sectors of the energy intensive industry in the EU: steel making, cement, oil refining and electricity generation. The steel industry is the most vulnerable industry, followed by oil refining, whereas cement and electricity are not vulnerable. At a permit price of 20 euros/ton CO2, and with national allocations that differ more than 40% in terms of allowed emissions per ton product output, this thesis predicts that some steel makers would be forced out of the market.

For a finite-dimensional simple Lie algebra {{g}}, we use the vertex tensor category theory of Huang and Lepowsky to identify the category of standard modules for the affine Lie algebra {{widehat{{g}}}} at a fixed level {ℓin{N}} with a certain tensor category of finite-dimensional {{g}}-modules. More precisely, the category of level ℓ standard {{widehat{{g}}}}-modules is the module category for the simple vertex operator algebra {L_{widehat{{g}}}(ℓ, 0)}, and as is well known, this category is equivalent as an abelian category to {{D}({g},ℓ)}, the category of finite-dimensional modules for the Zhu's algebra {A{(L_{widehat{{g}}}(ℓ, 0))}}, which is a quotient of {U({g})}. Our main result is a direct construction using Knizhnik-Zamolodchikov equations of the associativity isomorphisms in {{D}({g},ℓ)} induced from the associativity isomorphisms constructed by Huang and Lepowsky in {{L_{widehat{{g}}}(ℓ, 0) - {mod}}}. This construction shows that {{D}({g},ℓ)} is closely related to the Drinfeld category of {U({g})}[[h

In this series, the n-body reduced density matrix (n-RDM) approach for nonorthogonal orbitals and their applications to ab initio valence bond (VB) methods are presented. As the first paper of this series, Hamiltonian matrix elements between internally contracted VB wave functions are explicitly provided by means of nonorthogonal orbital based RDM approach. To this end, a more generalized Wick's theorem, called enhanced Wick's theorem, is presented both in arithmetical and in graphical forms, by which the deduction of expressions for the matrix elements between internally contracted VB wave functions is dramatically simplified, and the matrix elements are finally expressed in terms of tensor contractions of electronic integrals and n-RDMs of the reference VB self-consistent field wave function. A string-based algorithm is developed for the purpose of evaluating n-RDMs in an efficient way. Using the techniques presented in this paper, one is able to develop new methods and efficient algorithms for nonorthogonal orbital based many-electron theory much easier than by use of the first quantized formulism.

This article introduces a generative model of category representation that uses computer vision methods to extract category-consistent features (CCFs) directly from images of category exemplars. The model was trained on 4,800 images of common objects, and CCFs were obtained for 68 categories spanning subordinate, basic, and superordinate levels in a category hierarchy. When participants searched for these same categories, targets cued at the subordinate level were preferentially fixated, but fixated targets were verified faster when they followed a basic-level cue. The subordinate-level advantage in guidance is explained by the number of target-category CCFs, a measure of category specificity that decreases with movement up the category hierarchy. The basic-level advantage in verification is explained by multiplying the number of CCFs by sibling distance, a measure of category distinctiveness. With this model, the visual representations of real-world object categories, each learned from the vast numbers of image exemplars accumulated throughout everyday experience, can finally be studied.

Disordered eating behaviors and intentional pre-competition rapid weight loss are commonly seen in this population, attributed to weight categorization. We examined if height categories can be used as an alternative to weight categories for competition, in order to protect the health of athletes. Height and weight of 169 child and adolescent competitive karate athletes were measured. Participants were divided into eleven hypothetical weight categories of 5 kg increments, and eleven hypothetical height categories of 5 cm increments. We calculated the coefficient of variation of height and weight by each division method. We also calculated how many participants fit into corresponding categories of both height and weight, and how many would shift a category if divided by height. There was a high correlation between height and weight (r = 0.91, peating disorders in combat sports should be further examined. PMID:26557193

Compactly accessible categories and quantum key distribution
Heunen, Chris
2008-01-01
Compact categories have lately seen renewed interest via applications to quantum physics. Being essentially finite-dimensional, they cannot accomodate (co)limit-based constructions. For example, they cannot capture protocols such as quantum key distribution, that rely on the law of large numbers. To overcome this limitation, we introduce the notion of a compactly accessible category, relying on the extra structure of a factorisation system. This notion allows for infinite dimension while retaining key properties of compact categories: the main technical result is that the choice-of-duals functor on the compact part extends canonically to the whole compactly accessible category. As an example, we model a quantum key distribution protocol and prove its correctness categorically.
Infinite Index Subfactors and the GICAR Categories
Jones, Vaughan F. R.; Penneys, David
2015-10-01
Given a II1-subfactor of arbitrary index, we show that the rectangular GICAR category, also called the rectangular planar rook category, faithfully embeds as A - A bimodule maps among the bimodules . As a corollary, we get a lower bound on the dimension of the centralizer algebras for infinite index subfactors, and we also get that is nonabelian for , where is the Jones tower for . We also show that the annular GICAR/planar rook category acts as maps amongst the A-central vectors in , although this action may be degenerate. We prove these results in more generality using bimodules. The embedding of the GICAR category builds on work of Connes and Evans, who originally found GICAR algebras inside Temperley-Lieb algebras with finite modulus.

Neural responses to category ambiguous words
Conwell, Erin
2015-01-01
Category ambiguous words (like hug and swing) have the potential to complicate both learning and processing of language. However, uses of such words may be disambiguated by acoustic differences that depend on the category of use. This article uses an event-related potential (ERP) technique to ask whether adult native speakers of English show neural sensitivity to those differences. The results indicate that noun and verb tokens of ambiguous words produce differences in the amplitude of the ER...

On the flexibility of phonetic categories
Francis, Alexander L.; Nusbaum, Howard C.
2002-05-01
Research on phonetic category acquisition suggests that over the course of development children shift the relative weight given to various acoustic cues to particular phonetic categories [S. Nittrouer, J. Phon. 20, 1-32 (1992)]. Adults also show flexibility in acquiring second language categories and learning to recognize synthetic speech. In both cases listeners must shift attention among some acoustic cues and change the weighting and mapping of others. Recent research demonstrated that category-level feedback can induce adult listeners to shift attention between conflicting cues to native stop-consonant categories. Subsequent research showed that adult listeners also reorganize the distribution of their attention to acoustic cues in learning to better understand synthetic speech. Moreover, research on learning foreign phonetic contrasts suggests that listeners can learn to direct attention to unfamiliar acoustic cues. These results suggest that phonetic categories are flexible in terms of the nature and quality of the acoustic cues that define them. We argue that this flexibility is a consequence of the basic nature of the general mechanism that mediates speech perception: In order to resolve the problem of context-conditioned variability, listeners must dynamically modify attention to the acoustic signal in a context-dependent manner.

Moreover, in the case of finite dimensional, we will show that this category coincides with the corepresentation of a certain coquasitriangular Turaev group algebra that we construct. Finally we apply our theory to the case of group algebra.

Audience segmentation is a useful tool for designing effective campaigns. Further, the efficiency promised in diffusion science rests to some degree on the existence of adopter categories that can be identified and used to strategically disseminate prevention innovations. This study investigates the potential to identify adopter categories in potential recipients (n = 127) of an innovation to prevent food shortages in Mozambique. A 5-class model was found using latent class analysis, but it showed important differences from existing descriptions of adopter categories. Implications for theory and practice are discussed.

Full Text Available Previous research suggests that high functioning children with Autism Spectrum Disorder (ASD sometimes have problems learning categories, but often appear to perform normally in categorization tasks. The deficits that individuals with ASD show when learning categories have been attributed to executive dysfunction, general deficits in implicit learning, atypical cognitive strategies, or abnormal perceptual biases and abilities. Several of these psychological explanations for category learning deficits have been associated with neural abnormalities such as cortical underconnectivity. The present study evaluated how well existing neurally-based theories account for atypical perceptual category learning shown by high functioning children with ASD across multiple category learning tasks involving novel, abstract shapes. Consistent with earlier results, children’s performances revealed two distinct patterns of learning and generalization associated with ASD: one was indistinguishable from performance in typically developing children; the other revealed dramatic impairments. These two patterns were evident regardless of training regimen or stimulus set. Surprisingly, some children with ASD showed both patterns. Simulations of perceptual category learning could account for the two observed patterns in terms of differences in neural plasticity. However, no current psychological or neural theory adequately explains why a child with ASD might show such large fluctuations in category learning ability across training conditions or stimulus sets.

Kenneth N. Waltz's 1979 book, Theory of International Politics, is the most influential in the history of the discipline. It worked its effects to a large extent through raising the bar for what counted as theoretical work, in effect reshaping not only realism but rivals like liberalism and......-empiricism and anti-positivism of his position. Followers and critics alike have treated Waltzian neorealism as if it was at bottom a formal proposition about cause-effect relations. The extreme case of Waltz being so victorious in the discipline, and yet being consistently mis-interpreted on the question of...
Editorial: International Entrepreneurial Orientation
Krzysztof Wach
2015-01-01
In recent decades, both the theory of internationalisation of the firm and/or the theory of international business have developed. Recent developments in international business studies prove that entrepreneurial orientation (EO) emerges as one of the important potential factors contributing to the intensification of the processes of internationalisation of the firm (Etemad, 2015; Gupta & Gupta, 2015). It seems that international entrepreneurship (IE) has been flourishing. The general theory o...

Today’s categories for responding to targeted violence are motive-based and tend to drive policies, practices, training, media coverage, and research. These categories are based on the assumption that there are significant differences between ideological and non-ideological actors and between domestic and international actors. We question the reliance on these categories and offer an alternative way to frame the response to multiple forms of targeted violence. We propose adopting a community-based multidisciplinary approach to assess risk and provide interventions that are focused on the pre-criminal space. We describe four capabilities that should be implemented locally by establishing and maintaining multidisciplinary response teams that combine community and law-enforcement components: (1) community members are educated, making them better able to identify and report patterns associated with elevated risk for violence; (2) community-based professionals are trained to assess the risks for violent behavior posed by individuals; (3) community-based professionals learn to implement strategies that directly intervene in causal factors for those individuals who are at elevated risk; and (4) community-based professionals learn to monitor and assess an individual’s risk for violent behaviors on an ongoing basis. Community-based multidisciplinary response teams have the potential to identify and help persons in the pre-criminal space and to reduce barriers that have traditionally impeded community/law-enforcement collaboration.

In most combat sports and martial arts, athletes compete within weight categories. Disordered eating behaviors and intentional pre-competition rapid weight loss are commonly seen in this population, attributed to weight categorization. We examined if height categories can be used as an alternative to weight categories for competition, in order to protect the health of athletes. Height and weight of 169 child and adolescent competitive karate athletes were measured. Participants were divided i...
Category theoretic analysis of hierarchical protein materials and social networks
Spivak, David I; Buehler, Markus J
2011-01-01
Materials in biology span all the scales from Angstroms to meters and typically consist of complex hierarchical assemblies of simple building blocks. Here we review an application of category theory to describe structural and resulting functional properties of biological protein materials by developing so-called ologs. An olog is like a "concept web" or "semantic network" except that it follows a rigorous mathematical formulation based on category theory. This key difference ensures that an olog is unambiguous, highly adaptable to evolution and change, and suitable for sharing concepts with other ologs. We consider a simple example of an alpha-helical and an amyloid-like protein filament subjected to axial extension and develop an olog representation of their structural and resulting mechanical properties. We also construct a representation of a social network in which people send text-messages to their nearest neighbors and act as a team to perform a task. We show that the olog for the protein and the olog f...

A Probabilistic Account of Exemplar and Category Generation
Jern, Alan; Kemp, Charles
2013-01-01
People are capable of imagining and generating new category exemplars and categories. This ability has not been addressed by previous models of categorization, most of which focus on classifying category exemplars rather than generating them. We develop a formal account of exemplar and category generation which proposes that category knowledge is…
Symmetric centres of braided monoidal categories

This paper introduces the concept of‘symmetric centres' of braided monoidal categories. Let H be a Hopf algebra with bijective antipode over a field k. We address the symmetric centre of the Yetter-Drinfel'd module category HH(yD) and show that a left Yetter-Drinfel'd module M belongs to the symmetric centre of HH(yD) if and only if M is trivial. We also study the symmetric centres of categories of representations of quasitriangular Hopf algebras and give a sufficient and necessary condition for the braid of H(M) to induce the braid of (H(H)(A),(○)A,A,φ,l,r), or equivalently, the braid of (A#H(H),(○)A,A,φ,l,r), where A is a quantum commutative H-module algebra.
Category analysis: from biochemical mechanics to astrophysics
International Nuclear Information System (INIS)
Full text: One of the main goals of this report is to bridge the gap between computer modelling and group analysis of nonlinear partial differential equations. But we can work with a category of groups rather than a Lie group. In view of the experience of the past development of the relation between mathematics, mechanics and physics, the categorical extension may be justified that one day categoric structures will be as important as groups are today. Also our aim is the application of the same category-theoretic methods in biochemical mechanics and astrophysics. As examples we consider the category analysis of material models for concrete, wood and reinforcing or prestressing steel, on the one hand, and process of the linear and circular polarization of the cosmic microwave background radiation due to the quantum effects of electromagnetic field in anisotropic Bianchi-type cosmological models, on the other hand.

We present an extended implementation of the multireference configuration interaction (MRCI) method combined with the quantum-chemical density matrix renormalization group (DMRG). In the previous study, we introduced the combined theory, referred to as DMRGMRCI, as a method to calculate high-level dynamic electron correlation on top of the DMRG wave function that accounts for active-space (or strong) correlation using a large number of active orbitals. The DMRG-MRCI method is built on the full internal-contraction scheme for the compact reference treatment and on the cumulant approximation for the treatment of the four-particle rank reduced density matrix (4-RDM). The previous implementation achieved the MRCI calculations with the active space (24e,24o), which are deemed the record largest, whereas the inherent Nact 8 × N complexity of computation was found a hindrance to using further large active space. In this study, an extended optimization of the tensor contractions is developed by explicitly incorporating the rank reduction of the decomposed form of the cumulant-approximated 4-RDM into the factorization. It reduces the computational scaling (to Nact7 × N) as well as the cache-miss penalty associated with direct evaluation of complex cumulant reconstruction. The present scheme, however, faces the increased complexity of factorization patterns for optimally implementing the tensor contraction terms involving the decomposed 4-RDM objects. We address this complexity using the enhanced symbolic manipulation computer program for deriving and coding programmable equations. The new DMRG-MRCI implementation is applied to the determination of the stability of the iron(IV)-oxo porphyrin relative to the iron(V) electronic isomer (electromer) using the active space (29e,29o) (including four second d-shell orbitals of iron) with triple-ζ-quality atomic orbital basis sets. The DMRG-cu(4)-MRCI+Q model is shown to favor the triradicaloid iron(IV)-oxo state as the lowest
Compactly Generated Domain Theory

We propose compactly generated monotone convergence spaces as a well-behaved topological generalisation of directed-complete partial orders (dcpos). The category of such spaces enjoys the usual properties of categories of 'predomains' in denotational semantics. Moreover, such properties are retained if one restricts to spaces with a countable pseudobase in the sense of E. Michael, a fact that permits connections to be made with computability theory, realizability semantics and recent work on ...
Joins of DGA modules and sectional category
Fernández Suárez, Lucía; Ghienne, Pierre; Kahl, Thomas; Vandembroucq, Lucile
2009-01-01
We construct an explicit semifree model for the fiber join of two fibrations p: E --> B and p': E' --> B from semifree models of p and p'. Using this model, we introduce a lower bound of the sectional category of a fibration p which can be calculated from any Sullivan model of p and which is closer to the sectional category of p than the classical cohomological lower bound given by the nilpotency of the kernel of p^*: H^*(B;Q) --> H^*(E;Q). In the special case of the evaluation fibration X^I ...

The current study examines narratives elicited using a wordless picture book, focusing on language used to describe the characters' thoughts and emotions (i.e., internal state language, ISL). The sample includes 21 children with Autism Spectrum Disorder (ASD) and 24 typically developing controls, matched on children's gender, IQ, as well as receptive and expressive vocabulary. This research had three major findings. First, despite equivalent performance on standardized language assessments, the volume of children's narratives (i.e., the number of utterances and words, the range of unique verbs and adjectives) was lower in children with ASD than in typically developing controls. Second, after controlling for narrative volume, the narratives of children with ASD were less likely to reference the characters' emotions than was the case for typically developing controls. Finally, our results revealed a specific association between children's use of emotion terms and their performance on a battery of experimental tasks evaluating children's Theory of Mind abilities. Implications for our understanding of narrative deficits in ASD as well as interventions that use narrative as a context for improving social comprehension are discussed. PMID:24748899

Full Text Available No presente artigo se propõe as "relações em eixo" como um novo conceito paradigmático da Teoria das Relações Internacionais. Paradigma que, alcançado através da análise das relações bilaterais franco-alemãs e argentino-brasileiras, de 1870 aos nossos dias, permite analisar a formação, a condução e a consolidação de processos regionais de integração que têm por objectivo ultrapassar o quadro estritamente economicista das formas elementares de integração.The present article proposes the axis-relations as a new paradigmatical concept of the International Relations Theory. A paradigm which was reached through the analysis of the franco-german and the argentino-brazilien bilateral relations from 1870 to the present. It allows us to analyse the creation, conduction and consolidation of regional integration processes which have, as main goal, to surpass the economical step of the most elementary forms of regional integration.
