G.W. Leibniz, interrelations between mathematics and philosophy

CERN Document Server

Goethe, Norma B; Rabouin, David

2015-01-01

Up to now there have been scarcely any publications on Leibniz dedicated to investigating the interrelations between philosophy and mathematics in his thought. In part this is due to the previously restricted textual basis of editions such as those produced by Gerhardt. Through recent volumes of the scientific letters and mathematical papers series of the Academy Edition scholars have obtained a much richer textual basis on which to conduct their studies - material which allows readers to see interconnections between his philosophical and mathematical ideas which have not previously been manifested. The present book draws extensively from this recently published material. The contributors are among the best in their fields. Their commissioned papers cover thematically salient aspects of the various ways in which philosophy and mathematics informed each other in Leibniz's thought.

Leibniz's theory of bodies: monadic aggregates, phenomena, or both?

Directory of Open Access Journals (Sweden)

Christina Schneider

2001-12-01

Full Text Available Leibniz's conception of bodies seems to be a puzzling theory. Bodies are seen as aggregates of monads and as wellfounded phenomena. This has initiated controversy and unending discussions. The paper attempts to resolve the apparent inconsistencies by a new and formally spirited reconstruction of Leibniz's theory of monads and perception, on the one hand, and a (re-formulation and precisation of his concept of preestablished harmony, on the other hand. Preestablished harmony is modelled basically as a covariation between the monadic and the ideal realm.A concepção leibniziana dos corpos parece ser uma teoria enigmática. Corpos são vistos como agregados de mônadas e como fenômenos bem fundados. Isso deu origem a controvérsias e a discussões intermináveis. Este artigo tenta resolver as aparentes inconsistências por meio de uma reconstrução nova e formalmente inspirada da teoria da Leibniz das mônadas e da percepção, por um lado, e uma (reformulação mais precisa de seu conceito de harmonia pré-estabelecida, por outro lado. A harmonia pré-estabelecida é modelada basicamente como uma covariação entre o reino monádico e ideal.

The Leibniz principle in quantum logic

Giuntini, R.; Mittelstaedt, P.

The principle of the identity of indiscernibles (Leibniz Principle) is investigated within the framework of the formal language of quantum physics, which is given by an orthomodular lattice. The authors show that the validity of this principle is based on very strong preconditions (concerning the existence of convenient predicates) which are given in the language of classical physics but which cannot be fulfilled in orthomodular quantum logic

Theoretical construction in physics - The role of Leibniz for Weyl's 'Philosophie der Mathematik und Naturwissenschaft'

Science.gov (United States)

Sieroka, Norman

2018-02-01

This paper aims at closing a gap in recent Weyl research by investigating the role played by Leibniz for the development and consolidation of Weyl's notion of theoretical (symbolic) construction. For Weyl, just as for Leibniz, mathematics was not simply an accompanying tool when doing physics-for him it meant the ability to engage in well-guided speculations about a general framework of reality and experience. The paper first introduces some of the background of Weyl's notion of theoretical construction and then discusses particular Leibnizian inheritances in Weyl's 'Philosophie der Mathematik und Naturwissenschaft', such as the general appreciation of the principles of sufficient reason and of continuity. Afterwards the paper focuses on three themes: first, Leibniz's primary quality phenomenalism, which according to Weyl marked the decisive step in realizing that physical qualities are never apprehended directly; second, the conceptual relation between continuity and freedom; and third, Leibniz's notion of 'expression', which allows for a certain type of (surrogative) reasoning by structural analogy and which gave rise to Weyl's optimism regarding the scope of theoretical construction.

Epistemology as Information Theory: From Leibniz to Omega

Chaitin, G. J.

2005-01-01

In 1686 in his Discours de Metaphysique, Leibniz points out that if an arbitrarily complex theory is permitted then the notion of "theory" becomes vacuous because there is always a theory. This idea is developed in the modern theory of algorithmic information, which deals with the size of computer programs and provides a new view of Godel's work on incompleteness and Turing's work on uncomputability. Of particular interest is the halting probability Omega, whose bits are irreducible, i.e., ma...

Maupertuis, Leibniz, Least Action and Design

Simmons, James K.

2006-12-01

In current controversies regarding Intelligent Design (ID), critics of ID often claim that naturalisitc science (i.e., science that attempts to explain natural phenomena in terms of strictly non-supernatural processes) has such a good track record that there is no need to introduce supernatural design hypotheses into our thinking. Since ID is not a new idea, we can search through the history of science and look also at ID's track record. In this talk, we focus on the ID thinking of Maupertuis and Leibniz when the former developed the Principle of Least Action and when both of them applied the principle to Snell's law of refraction. In this case, we find that ID did no harm and made no lasting contribution.

Heisenberg's pioneering work ''Ueber quantentheoretische Umdeutung kinematischer und mechanischer Beziehungen'' (1925) illustrates corner points of Leibniz's theory of knowledge. It succeeds to distill kinematics of circles with velocity from an analysis of the Larmor model for the Zeeman effect. Aim of this novel kinematics is Heisenberg's time-free quantum algebra. The circle kinematica are strictly relational, and they can serve as fundament of a prototheory of quantum physics just to be developed. The kinematics of the circles implicates finally a staged term of illustrativeness. [de

Leibniz y el concepto de analogía

Directory of Open Access Journals (Sweden)

Oscar Miguel Esquisabel

2008-11-01

Full Text Available In this paper an analysis of the leibnizian applications of conceptof analogy as well as the analogical reasoning is approached. Thus, the analysis tries to show that the leibnizian concept of analogy is based on the idea of structural similarity. As a consequence of such consideration,two basic ways in which Leibniz applies analogical reasoning are examined. The first way has a conjectural character and is rather heuristic, whereas the second constitutes, at least in intention, a kind of demonstrative analogicalreasoning, since it tries to prove its conclusions for a determined theoreticaldomain by applying a transfer principle, which is itself founded on the identity of structural properties.This procedure is exemplified by outlining the leibnizian view on contingent truths. In this way, the paper concludesby pointing out the theoretical relevance of the concept of similarity in theleibnizian thought.

The Architect as Producer: Hannes Meyer and the Proletarianisation of the Western Architect

Directory of Open Access Journals (Sweden)

Amir Djalali

2015-12-01

Full Text Available With the foundation of the Bauhaus, Walter Gropius advocated an end to the division between arts and crafts. Contrary to the idea of architecture as art, the programme of the school aimed to assimilate architecture with industry in order to satisfy collective social needs. Yet, despite this programmatic declaration, such a project was realised only after Gropius’ departure from the Bauhaus, under the controversial directorship (1927–1930 of the Swiss architect Hannes Meyer. Meyer achieved unprecedented success both in terms of academic production and financial performance. Yet his realisations were paralleled by the leftist radicalisation of the school’s politics: Meyer transformed the workshops into factory production units and the students into industrial workers. Eventually, the politicisation of the school cost Meyer his office and a negative reputation in historical records that still holds today. This article posits that Meyer achieved his success at the Bauhaus not despite his radical allegiance, but precisely because of it. The realism of Meyer’s strategy is evaluated through his capacity to anticipate many developments in the organisation of architectural production. In particular, his critique of intellectual labour in architecture is confronted with the contemporary proletarisation of architects in the Western world.

2017-06-01

The current-voltage characteristics of the C70 solid with hexagonal closed-packed structures were measured in the temperature range of 250-450 K. The current-voltage characteristics can be described as a temporary expedient by a cubic polynomial of the voltage, i = a v 3 + b v 2 + c v + d . Moreover, the Meyer-Neldel temperature of the C70 solid was confirmed to be 310 K, at which a linear relationship between the current and voltage was observed. Also, at temperatures below the Meyer-Neldel temperature, the current increases with increasing voltage. On the other hand, at temperatures above the Meyer-Neldel temperature a negative differential conductivity effect was observed at high voltage side. The negative differential conductivity was related to the electric field and temperature effects on the mobility of charge carrier, which involve two variations in the carrier concentration and the activation energy for carrier hopping transport.

'Tipping the Balance': Karl Friedrich Meyer, Latent Infections, and the Birth of Modern Ideas of Disease Ecology.

Science.gov (United States)

Honigsbaum, Mark

2016-04-01

The Swiss-born medical researcher Karl Friedrich Meyer (1884-1974) is best known as a 'microbe hunter' who pioneered investigations into diseases at the intersection of animal and human health in California in the 1920s and 1930s. In particular, historians have singled out Meyer's 1931 Ludwig Hektoen Lecture in which he described the animal kingdom as a 'reservoir of disease' as a forerunner of 'one medicine' approaches to emerging zoonoses. In so doing, however, historians risk overlooking Meyer's other intellectual contributions. Developed in a series of papers from the mid-1930s onwards, these were ordered around the concept of latent infections and sought to link microbial behavior to broader bio-ecological, environmental, and social factors that impact hostpathogen interactions. In this respect Meyer-like the comparative pathologist Theobald Smith and the immunologist Frank Macfarlane Burnet-can be seen as a pioneer of modern ideas of disease ecology. However, while Burnet's and Smith's contributions to this scientific field have been widely acknowledged, Meyer's have been largely ignored. Drawing on Meyer's published writings and private correspondence, this paper aims to correct that lacuna while contributing to a reorientation of the historiography of bacteriological epidemiology. In particular I trace Meyer's intellectual exchanges with Smith, Burnet and the animal ecologist Charles Elton, over brucellosis, psittacosis and plague-exchanges that not only showed how environmental and ecological conditions could 'tip the balance' in favor of parasites but which transformed Meyer thinking about resistance to infection and disease.

A variação no volume de conflitos esteve também associada a variáveis econômicas (especialmente a inflação, mas de forma secundária. Nos últimos 30 anos, a inclusão de diversos segmentos sociais no âmbito da esfera política, em sentido lato, redesenhou o mapa dos "incluídos". Esse processo começou com a liberalização política em meados dos anos de 1970, foi reforçado pelas primeiras greves no ABC paulista em 1978 e teve continuidade pelas mais diversas formas de transformação do Estado nos vários governos subsequentes, de Sarney a Lula.The article analyzes the beginning, peak and decline of a cycle of strikes in Brazil which can be considered as the most important one in the country's history due to its characteristics and intensity, reaching one of the highest levels compared to other western countries between 1985 and 1992.

Full Text Available A importância da trajetória de Philip Meyer para os estudos de jornalismo é o ponto principal desta entrevista. Ele é o criador do Jornalismo de Precisão, conceito que aproxima o jornalismo da ciência por meio de métodos científicos sociais, e que, também, dá nome a um de seus livros, publicado pela primeira vez em 1973. Ainda que o Jornalismo de Precisão não demande, necessariamente, o uso de computadores, Meyer começou a trabalhar com as máquinas antes de sua popularização, nos protestos de Detroit, em 1967, depois de passar nove meses na Universidade de Harvard. Utilizando amostra na narrativa jornalística, Meyer e a equipe do jornal Detroit Free Press receberam um Prêmio Pulitzer um ano depois. O Jornalismo de Precisão ainda é um conceito utilizado, mas hoje mais associado ao jornalismo de dados. Nessa entrevista, respondida por email, Meyer não só relembra aspectos de sua carreira e fala sobre a prática jornalística, como o uso de dados, transparência e hipótese, bem como revela suas percepções sobre o futuro do jornalismo.

Full Text Available Resumo: os ciclos de greves dos professores da rede pública de ensino doEstado do Paraná, que culminaram no trágico episódio repressivo de 29 de abril de 2015, foram atravessados por uma intensa disputa pela condução e pelo controle dos signos que se plasmariam na opinião pública. O governo estadual procurava alterar os significados sociais dos três eixos que, ao se confundirem ao infinito, compunham o potencial coletivo das greves dos professores do Estado: sua política, sua subjetividade e sua resistência. É ao redor desses três eixos, e de suas hibridações práticas, que se pretende analisar a conjuntura política dos ciclos das greves de 2015, descrevendo suas conexões inaparentes com as novas dinâmicas de manifestações populares, que encontram seu marco nos levantes que se iniciaram em junho de 2013, os processos de subjetivação envolvidos e as ramificações locais das lutas do público e do comum contra medidas de austeridade. Para tanto, o texto se vale do método de análise da conjuntura política que envolve o episódio de 29 de abril, fundada teoricamente em categorias filiadas pós-estruturalismo contemporâneo – sobretudo à obra de Michael Hardt e Antonio Negri – e empiricamente na análise de crítica de artigos de jornais, periódicos e sites a respeito do objeto de estudo. Palavras-Chave: Greves. Estado do Paraná. Movimentos Sociais. Contemporâneos. Análise de conjuntura.Abstract: The educational strikes in Paraná, which resulted in the tragic repressive episode of April 29th 2015, were crossed by an intense dispute to conduct and control the signs from which public opinion would later emerge. The State government tried to modify the social meaning of three political axes consisting in the collective potential of those strikes: their politics, subjectivity and forms of resistance. Concerning these three axes, and their processes and practices of hybridation, this essay aims to analyse the political

Full Text Available Hannes Meyer arrived in Mexico in 1938 to take part in the XVIth International Housing and Town Planning Congress. One year later he founded the Institute for Urban Development and Planning and stayed in Mexico for the next ten years undertaking various urban projects such as the Lomas de Becerra Apartment Block, the Corpus Christi block, and the Agua Hedionda beach resort. Each one of these is the result of a dialectic process with his previous phases of work in which it is possible to see elements such as his Swiss-German and Soviet ideas. Over this article his emphasis on science will be highlighted.

Aneignung und Interpretation der monadologischen Metaphysik von Leibniz durch die Metaphysik des Daseins

Directory of Open Access Journals (Sweden)

Hardy Neumann

2014-06-01

Full Text Available The research of H.-G. Gadamer and F. Volpi have showed the intimate connection between Sein und Zeit and the philosophy of Aristotle, specially the Nicomachean Ethics. The influence of other thinkers on the hermeneutical phenomenology has received less attention. Amongst the thinkers, whose contributions have not been sufficiently highlighted figures Leibniz. In this context, some relations between Leibniz’s monadological thinking and the metaphysics of Heidegger’s Dasein are considered and interpreted in this paper. It is argued that, to certain extent, an appropriation of Monadology’s metaphysics takes place in Dasein’s metaphysics.

Leibniz's relationalism and the crisis of Anschauung in quantum mechanics; Der Relationalismus von Leibniz und die Krise der Anschauung in der Quantenmechanik

Herbig, Ralf

2009-05-07

Heisenberg's pioneering work ''Ueber quantentheoretische Umdeutung kinematischer und mechanischer Beziehungen'' (1925) illustrates corner points of Leibniz's theory of knowledge. It succeeds to distill kinematics of circles with velocity from an analysis of the Larmor model for the Zeeman effect. Aim of this novel kinematics is Heisenberg's time-free quantum algebra. The circle kinematica are strictly relational, and they can serve as fundament of a prototheory of quantum physics just to be developed. The kinematics of the circles implicates finally a staged term of illustrativeness. [German] Heisenbergs Pionierarbeit ''Ueber quantentheoretische Umdeutung kinematischer und mechanischer Beziehungen'' (1925) illustriert Eckpunkte der Leibnizschen Erkenntnistheorie. Es gelingt, eine Kinematik von Kreisen mit Geschwindigkeit aus einer Analyse des Larmor-Modells fuer den Zeeman-Effekt herauszudestillieren. Zielrichtung dieser neuartigen Kinematik ist Heisenbergs zeitfreie Quantenalgebra. Die Kreiskinematik ist strikt relational, und sie kann als Fundament einer erst noch zu entwickelnden Prototheorie der Quantenphysik dienen. Die Kinematik der Kreise mit Geschwindigkeit impliziert schliesslich einen gestuften Begriff von Anschaulichkeit. (orig.)

Interpretation and consequences of Meyer-Neldel rule for conductivity of phase change alloys

Measurements of conductivity as a function of temperature were performed on a large number of memory cells of a GeSbTe phase change memory alloy, in both the set and reset states. Conductivity obeys the Meyer-Neldel rule in both states, with the same Meyer-Neldel, or isokinetic, temperature, but with conductivity prefactors about six orders of magnitude larger in the set than in the reset state. These observations are interpreted in terms of the multiexcitation entropy model, and conduction mechanisms are suggested. Their effect on the expected behavior of memories is considered.

The reflective look of Pedro Meyer: photography as the photography mediation problematic O olhar reflexivo de Pedro Meyer: a fotografia como problematizadora da própria mediação fotográfica

Ana Carolina Lima Santos

2011-08-01

Full Text Available This paper discusses Pedro Meyer’s photographs with special attention to the way that they are arranged as a kind of reflection about the language of photography and its capacity of mediation. In that, the pictures made by Meyer seem to have a symbolic dimension, which request a conscious activity of the spectator – contradicting the idea of image as a form of alienation proposed by Guy Debord. O presente artigo propõe uma discussão acerca do trabalho do fotógrafo Pedro Meyer a partir do entendimento de que suas imagens, ao explicitar e esgarçar limites de noções caras à natureza do fotográfico, funcionam como reflexão sobre a linguagem fotográfica e o seu poder de mediação. Discute-se, assim, como as imagens de Meyer assumem uma dimensão simbólica que solicitam do espectador uma prática de ativa – opondo-se à noção debordiana de imagens alienantes.

Impact of implementing the Meyer-Neldel behavior of carrier emission pre-factors in solar cell and optical detector modeling

The Meyer-Neldel behavior reported for the emission probabilities of electrons and holes was included in our code, replacing the gap state capture cross sections of the Shockley-Read-Hall formalisms with capture cross sections containing an exponential function of the trap energy depth. The Meyer-Neldel energies for electrons and holes are the slopes of these exponentials. Our results indicate that emission probabilities of neutral states no deeper than approximately 0.45 eV and 0.37 eV from the conduction and valence band edges, respectively, can show a Meyer-Neldel behavior only, while on the other hand, its implementation in deeper gap states makes the replication of experimental J-V curves of p-i-n solar cells and detectors impossible. The Meyer-Neldel behavior can be included in all neutral capture cross sections of acceptor-like tail states without affecting the J-V characteristics, while it cannot be included in all capture cross sections of neutral donor-like tail states and/or defect states without predicting device performances below the experimental figures, that become even lower when it is also included in charged capture cross sections. The implementation of the anti Meyer-Neldel behavior at tail states gives rise to slightly better and reasonable device performances.

Application of a generalized Leibniz rule for calculating electromagnetic fields within continuous source regions

International Nuclear Information System (INIS)

Silberstein, M.

1991-01-01

In deriving the electric and magnetic fields in a continuous source region by differentiating the vector potential, Yaghjian (1985) explains that the central obstacle is the dependence of the integration limits on the differentiation variable. Since it is not mathematically rigorous to assume the curl and integral signs are interchangeable, he uses an integration variable substitution to circumvent this problematic dependence. Here, an alternative derivation is presented, which evaluates the curl of the vector potential volume integral directly, retaining the dependence of the limits of integration on the differentiation variable. It involves deriving a three-dimensional version of Leibniz' rule for differentiating an integral with variable limits of integration, and using the generalized rule to find the Maxwellian and cavity fields in the source region. 7 refs

This paper is mainly connected with the approximation properties of Meyer-Koenig and Zeller (MKZ) type operators. We first introduce a general sequence of MKZ operators based on q-integers and then obtain a Korovkin-type approximation theorem for these operators. We also compute their rates of convergence by means of modulus of continuity and the elements of Lipschitz class functionals. Furthermore, we give an rth order generalization of our operators in order to get some explicit approximation results.

Leibniz on the parallel postulate and the foundations of geometry the unpublished manuscripts

CERN Document Server

De Risi, Vincenzo

2016-01-01

This book offers a general introduction to the geometrical studies of Gottfried Wilhelm Leibniz (1646-1716) and his mathematical epistemology. In particular, it focuses on his theory of parallel lines and his attempts to prove the famous Parallel Postulate. Furthermore it explains the role that Leibniz’s work played in the development of non-Euclidean geometry. The first part is an overview of his epistemology of geometry and a few of his geometrical findings, which puts them in the context of the seventeenth-century studies on the foundations of geometry. It also provides a detailed mathematical and philosophical commentary on his writings on the theory of parallels, and discusses how they were received in the eighteenth century as well as their relevance for the non-Euclidean revolution in mathematics. The second part offers a collection of Leibniz’s essays on the theory of parallels and an English translation of them. While a few of these papers have already been published (in Latin) in the standard Le...

Full Text Available RESUMEN Hannes Meyer fue uno de los arquitectos más comprometidos con las ideas del ala radical del racionalismo, que él mismo y otros grandes arquitectos, como Mart Stam, Hans Wittwer, Karel Teige, Ludwig Hilberseimer o Ernst May, desarrollaron durante la década de los años veinte. Su voluntad de desvincular la arquitectura del “high–art” burgués y de todo simbolismo propio del pasado, de producir construcciones de carácter objetivo y social, quedó patente en proyectos y obras firmadas por todos ellos: en el caso de Meyer, probablemente, la construcción que mejor expresa tales postulados y aquel nuevo modo de hacer arquitectura sea la Escuela Federal ADGB; construida en Bernau entre 1928 y 1930. El presente artículo estudia la citada obra, a la luz del ideario arquitectónico y social de arquitecto suizo, y trata de exponer la estrategia que se encuentra detrás de su formalización: la serie. En efecto, a partir de este mecanismo de proyecto, basado en la repetición o reproducción casi infinita de sistemas constructivos o de unidades del programa–o de ambas al mismo tiempo–aquellos arquitectos descubrieron un nuevo modo de generar la forma arquitectónica, moderno y muy poco explorado hasta entonces. Una vía donde valores como la horizontalidad, la ausencia de centro o jerarquía, la igualdad y la objetividad se erigían como el nuevo relato de la arquitectura. SUMMARY Hannes Meyer was one of the most committed architects to the ideas of the radical wing of rationalism, which he himself and other great architects, such as Mart Stam, Hans Wittwer, Karel Teige, Ludwig Hilberseimer and Ernst May, developed during the twenties. Their desire to unshackle architecture from bourgeois “high art” and from all symbolism from the past, to produce constructions of an objective and social nature, was made patent in the designs and works signed by all of them. With regard to Meyer, the construction which best expresses these

It is shown that the models recently proposed by Meyer, Kent, and Clifton (MKC) exhibit a novel kind of contextuality, which we term existential contextuality. In this phenomenon it is not simply the pre-existing value but the actual existence of an observable which is context dependent. This result confirms the point made elsewhere, that the MKC models do not, as the authors claim, 'nullify' the Kochen-Specker theorem. It may also be of some independent interest

Increased demand for applied behavior analysis (ABA) services has increased the need for additional masters-level practitioners and doctoral-level academicians and clinical directors. Based on these needs, the University of Nebraska Medical Center's (UNMC) Munroe-Meyer Institute has developed a PhD program. The academic structure at UNMC allowed us to create our PhD program in a relatively quick and efficient manner. Our PhD program has many unique features, including (a) close integration of didactic instruction with clinical and research training provided by leading experts in ABA in which students immediately apply concepts introduced in the classroom during coordinated clinical and research practica; (b) structured grant writing training in which students learn to write and submit an NIH-level grant; (c) financial support in the form of a stipend of $23,400 per year, free health benefits, and a full-tuition waiver for up to 12 credits per semester for UNMC courses (a benefits package worth approximately $50,000 per year for an out-of-state student); and (d) encouragement and financial support to present papers at local, regional, and national behavior analysis conferences.

The nature of barriers for atomic transport in In{sub 2}S{sub 3} layers has been varied by addition of chlorine. Diffusion of Cu(I) from a removable CuSCN source was used to probe the variation of the barriers. The Meyer-Neldel (compensation) rule was observed with a Meyer-Neldel energy (E{sub MN}) and a proportionality prefactor (D{sub 00}) amounting to 40 meV and 5 × 10{sup −14} cm{sup 2}/s, respectively. D{sub 00} shows that the elementary excitation step is independent of the specific mechanism and nature of the barrier including different densities of Cl in In{sub 2}S{sub 3}. The value of E{sub MN} implies that coupling of the diffusing species to an optical-phonon bath is the source of the multiple excitations supplying the energy to overcome the diffusion barriers.

14C-AMS at the Leibniz-Labor: radiometric dating and isotope research

International Nuclear Information System (INIS)

Grootes, Pieter M.; Nadeau, Marie-Josee; Rieck, Anke

2004-01-01

The Leibniz-Labor was founded to provide radiometric dating services using AMS and measured over 15 000 samples and 26 800 targets up to September 2002. Research and development have primarily been directed at improving the efficiency and reliability of AMS measurements, optimising existing sample preparation procedures for AMS and developing new ones. The standard chemical pre-treatment of organic radiocarbon samples produces often two fractions: one from which contaminants have been removed, and one in which they have been enriched. Dating both fractions reveals the degree of sample contamination. This provides a useful indication of the reliability of the sample age obtained and of the environmental conditions where the sample was taken. Upgrades to reduce maintenance include replacing four cryo- by turbo pumps, installing a deionizer loop, which keeps conductivity between 100 and 150 μS/cm to control corrosion, in the closed cooling water circuit, and developing a new sample wheel, which holds target holders with a groove and spring clip. Long term stability is demonstrated by the results obtained for IAEA reference materials, measured routinely and regularly over the years. Tests made as part of the FIRI project demonstrate that reliable measurements down to <0.1 mg C can be made

2015-01-01

Full Text Available The target of this paper is to establish the bid-ask pricing framework for the American contingent claims against risky assets with G-asset price systems on the financial market under Knightian uncertainty. First, we prove G-Dooby-Meyer decomposition for G-supermartingale. Furthermore, we consider bid-ask pricing American contingent claims under Knightian uncertainty, by using G-Dooby-Meyer decomposition; we construct dynamic superhedge strategies for the optimal stopping problem and prove that the value functions of the optimal stopping problems are the bid and ask prices of the American contingent claims under Knightian uncertainty. Finally, we consider a free boundary problem, prove the strong solution existence of the free boundary problem, and derive that the value function of the optimal stopping problem is equivalent to the strong solution to the free boundary problem.

One Hundred Years of Psychiatry at Johns Hopkins: A Story of Meyer to McHugh.

Science.gov (United States)

DePaulo, J Raymond

2017-04-01

This article describes a history of clinical methods and constructs that guide Psychiatry at Johns Hopkins Phipps Clinic today. The contributions of Adolf Meyer and Paul McHugh are central and closely connected. Both emphasize the clinical examination as the central practice of psychiatry as a specialty within medicine. Meyer's comprehensive examination of the patient became the centerpiece of his approach and was the standard for psychiatrists in the English-speaking world. McHugh, with Phillip Slavney, developed a pluralistic and practical framework for interpreting that history and examination. Both argued against the uncritical use of the modern disease construct. McHugh argues that the disease construct, although fundamental, is but one of four useful "perspectives of psychiatry" and is, thus, an insufficient basis for psychiatric practice. The perspectives could be used as an organizing framework by all physicians who seek a practical and truly personalized approach to the care of patients.

The history of the priority di∫pute between Newton and Leibniz mathematics in history and culture

CERN Document Server

Sonar, Thomas

2018-01-01

This book provides a thrilling history of the famous priority dispute between Gottfried Wilhelm Leibniz and Isaac Newton, presenting the episode for the first time in the context of cultural history. It introduces readers to the background of the dispute, details its escalation, and discusses the aftermath of the big divide, which extended well into recent times. One of the unique features of the book is that the mathematics behind the story is very intelligibly explained – an approach that offers general readers interested in the history of sciences and mathematics a window into the world of these two giants in their field. From the epilogue to the German edition by Eberhard Knobloch: Thomas Sonar has traced the emergence and the escalation of this conflict, which was heightened by Leibniz’s rejection of Newton’s gravitation theory, in a grandiose, excitingly written monograph. With absolute competence, he also explains the mathematical context so that non-mathematicians will also profit from the book....

Using an overall sample of 278 individuals who had taken the Minnesota Multiphasic Personality Inventory-Second Edition (MMPI-2) and who had clear diagnostic information available in their medical records, the Meyers Index (MI) for the MMPI-2 (Meyers, Millis, & Volkert, 2002 ) was calculated for each individual, and a new version of the MI created for the MMPI-2 Restructured Form (MMPI-2-RF) was calculated. The MI is a method of combining multiple MMPI-2 validity scales into a single weighted index to assess exaggerated self-report on the MMPI-2. The new index is intended to provide the same type of global assessment of validity but for the MMPI-2-RF (MI-r). The MI and the MI-r were compared at both individual and group levels and were found to correlate well (r = .87). Diagnostic groups of litigants and nonlitigants of traumatic brain injury, chronic pain, and posttraumatic stress disorder were also examined; and the performance of the MI and the MI-r were similar. Similarly, the pass and fail agreement rate for the two scales was 93%. The results indicate that the MI and MI-r perform very similarly and are good methods of assessing overall validity of MMPI-2 and MMPI-2-RF test performance.

Thought Experiments in Historiographic Function: Max Weber on Eduard Meyer and the Question of Counterfactuality. Max Weber's remarks on his colleague Eduard Meyer regarding counterfactual reasoning in history reflects a significant shift during the Methodenstreit around 1900. The question of attributing historical change strictly to either individual causes or abstract general laws has been tackled in a new way: By counterfactual reasoning a historian should be able to detect the most significant (and therefore meaningful) cause, event, or action for a certain historical outcome. Following Fritz Ringer, this paper argues that given the predominating methods of the natural sciences, scholars of the humanities conducted historical research by counterfactual thought experiments. This way, Weber pried open contemporary narratives (e.g. historicism), and by employing a unique historical causal analysis he made way for refined concepts to offer a model of interpretation that gave hope for a more feasible, practice-oriented approach to historical research than the epistemological discussions had hitherto offered. © 2015 WILEY-VCH Verlag GmbH & Co.

Full Text Available Our present knowledge in the field of dynamical systems, information theory, probability theory and other similar domains indicates that the human brain is a complex dynamical system working in a strong chaotic regime in which random processes play important roles. In this environment our mental life develops. To choose a logically ordered sequence from a random or almost random stream of thoughts is a difficult and energy consuming task. The only domain in which we are able to do this with a full success is mathematics. Leibniz’s life ambition was to extend this success, with the help of what he called characteristica universalis, to other areas of human activity. The belief that this is possible lies at the basis of Leibniz’s rationalist system. Reasoning within his system, Leibniz claimed that also fundamental laws of physics can be deduced from the “first principles”. Just as linguistic or conceptual units are at the basis of the charactersistica universalis, his monads are responsible for physical activity of material bodies. When this rationalistic strategy is applied to the philosophy of space and time, it leads to their radically relational conception. Leibniz’s rationalistic approach to philosophy and science arouses out sympathy but it was Newton’s mathematical-empirical method that turned out to be effective in human endeavour to understand the functioning of the physical world. Successes of the Newtonian method compel us to revise our concept of rationality.

Full Text Available How knowledge is negotiated between the makers of encyclopedias and their audiences remains an ongoing question in research on encyclopedias. A comparative content analysis of the published answers of letters to the editor of the German Meyers Konversationslexikon (Korrespondenzblatt from 1885 and the discussion pages of the article potato of the German Wikipedia (2013 reveals continuities as well as changes in the communication between encyclopedia producers and their audiences. The main reasons why readers and editors communicate are the need for updated factual information, an exchange on editorial principles and the intellectual exchange of ideas on ideological and philosophical questions in relation to the encyclopedic content. Editors and readers attach a lot of importance to the process of verifying information through bibliographical references. Whereas, for the editors of Meyers Konversationslexikon the leading role of experts remains undisputed, Wikipedians work in a contradictory situation. They are on the one hand exposing knowledge production to a permanent process of negotiation, thereby challenging the role of experts, on the other hand relying strongly on bibliographical authorities. Whilst the reasons for the communication between readers and editors of Meyers Konversationslexikon and among Wikipedia contributors coincide, the understanding of the roles of readers and editors differ. The editors of the Korrespondenzblatt keep up a lecturing attitude. As opposed to this, administrators in Wikipedia want to encourage participation and strive to develop expertise among the participating contributors. Albeit power relations between administrators, regular authors, occasional authors and readers continue to exist they are comparatively flat and transient. Regardless of these differences, the comparison between Meyers Konversationslexikon and Wikipedia indicates that the sine qua non for activating an upwards spiral of quality

The Unifying Strands: Formalism and Gestalt Theory in the Musical Philosophies of Aristoxenus, Descartes, and Meyer

Full Text Available In every age, philosophers deal with inquiries concerning musical meaning and the effect of music on the listener. Instead of answering the formidable question of musical meaning, this essay demonstrates the parallel aspects of three musical theories from ancient, Enlightenment, and modern times. Using the two criteria of musical formalism and Gestalt Theory, this essay systematically connects the philosophies of Aristoxenus of Tarentum, René Descartes, and Leonard Meyer. Musical formalism holds that music’s nature is innate, self-evident, able to be systematically deduced, and rational. According to formalism, musical meaning is defined by things objectively ‘there’ in the music, musical experience relies on cognition, and music is less a matter of sense than of mind. Gestalt Theory asserts that music is a unified totality—the whole gives meaning to the parts. This project demonstrates that three seemingly dissimilar musical philosophies include and prefigure the same foundational principles, although the theories reach different conclusions about musical meaning. In the research process, this essay utilizes documentary evidence. This essay concludes that the philosophies of Aristoxenus, Descartes, and Meyer are united by tendencies toward musical formalism and strands of the Gestalt view of music.

De mónadas y sustantividades o Leibniz y Zubiri

Full Text Available The risk of understanding authors incorrectly is proportional to their innovative nature. The context of reading and understanding innovative texts cannot be other than the traditional context previous to the innovation, in which the technical language of the discipline was coined. This language is also used by the innovator, filling the old words with new meanings. Consequently, the most natural way to understand innovative texts is to interpret them in the framework of the traditional received categories, losing all of their originality. This is apparent in the case of Zubiri’s philosophy, which has been frequently interpreted according to the categories common to the rationalistic tradition of Western philosophy. This article attempts to clarify this point, comparing the pure reason of Leibniz with the sentient or impure intelligence of Zubiri. These are two different ways of understanding thought and reality and, therefore, philosophy.Los autores resultan tanto más difíciles de entender cuanto más originales son sus planteamientos. El contexto de lectura de las obras de un innovador no puede ser otro que el previo a la innovación, aquel en que se acuñaron los términos que por necesidad él tendrá que utilizar, bien que dotándoles de nuevo sentido. Lo normal es que este nuevo sentido pase inadvertido para el lector, que tenderá a interpretar esos términos en su sentido tradicional. Esto es por demás evidente en el caso de la filosofía de Zubiri, al que con frecuencia se le ha interpretado con categorías racionalistas completamente extrañas a su pensamiento. En este artículo se intenta aclarar ese punto, confrontando la razón pura leibniziana con la inteligencia impura o sentiente de Zubiri. Son dos modos distintos de entender el pensamiento y la realidad, que generan a su vez dos teorías filosóficas divergentes.

Full Text Available Stroke is one of the major causes of morbidity and mortality. Sequels deriving from this event may lead to motor disability and from mild to severe deficits. In order to better classify sensory-motor dysfunction, balance and ability to perform activities of daily living, quantitative and qualitative evaluation scales have been used. OBJECTIVE: To correlate the scales Fugl-Meyer assessment scale, Berg balance scale and Barthel index. Twenty subjects with sequel after a single, unilateral stroke in chronic phase (>6 months post ictus were evaluated for about one hour. RESULTS: Barthel scale was statistically related to the total motor score of Fugl-Meyer assessment (r=0.597, p=0.005. The lower limb section at Fugl-Meyer had positive correlation with Berg scale (r=0.653, p=0.002 and with the balance section of Fugl-Meyer own scale (r=0.449, p=0.047. Both balance scales were correlated one with other (r=0.555, p=0.011. Statistical divergence appeared when Barthel's Index was correlated with Berg's Scale (r=0.425, p=0.062, and it is not statistically significant. CONCLUSION: The use of both quantitative and qualitative scales was shown to be a good measuring instrument for the classification of the general clinical performance of the patient, especially when positively related joint evaluations are applied.O acidente vascular cerebral (AVC é reconhecido como uma das maiores causas de morbidade e mortalidade.

Full Text Available RESUMO: A presente investigação questiona a essência teo-lógica dos futuros contingentes. Para o efeito, analisa-se, primeiramente, a argumentação segundo a qual, sob certas condições lógicas, teológicas, ontológicas e cosmológicas antinecessitantes, detetadas por G. W. Leibniz (conciliando a posição de St. Agostinho com a de L. Molina e W. Ockham, a abertura contingente do futuro parece ser compatível com o regime das "verdades contingentes pré-determinadas", regime enquadrado teologicamente pelo princípio do "futuro melhor" ou do "único futuro verdadeiro". No entanto, os futuros contingentes incitam, com e contra Aristóteles, ao desenvolvimento de uma lógica temporal e plurivalente, ao modo de J. Łukasiewicz ou A. Prior. Essa lógica garante a abertura do futuro sem o oneroso custo metafísico da adesão a uma teo-lógica omnideterminante. A crítica do determinismo lógico, daí resultante, afigura-se mais coadunável com as condições pós-metafísicas inerentes à episteme agnósticacontemporânea, mas, nesse caso, a abertura do futuro implicaria uma profunda redefinição das próprias ideias e funções de "Deus", "matéria", "história" e "verdade".

Wagner, Edwin E

2008-07-01

I present a formal system that accounts for the misleading distinction between tests formerly termed objective and projective, duly noted by Meyer and Kurtz (2006). Three principles of Response Rightness, Response Latitude and Stimulus Ambiguity are shown to govern, in combination, the formal operating characteristics of tests, producing inevitable overlap between "objective" and "projective" tests and creating at least three "types" of tests historically regarded as being projective in nature. The system resolves many past issues regarding test classification and can be generalized to include all psychological tests.

The aim of the present study was to assess the drying kinetic of tucum fruits (epicarp and mesocarp) Astrocaryum aculeatum Meyer at three different temperatures (50, 60, and 70 °C). The physicochemical characterization, water activity, moisture content, including β-carotene and vitamin C content in - natura and dried fruits were analyzed. The fruit fractions presented high β-carotene, protein and lipid levels. Fatty acid profile showed oleic acid as the major fatty acid. Different mathematical models were computed to assess the drying process. The Page model was observed to be the best to describe the drying kinetic with the highest correlation coefficient ( R 2 ) 0.99 and the least Chi squared ( χ 2 ) close to 10 5 at the studied temperatures. The drying process reduced water activity to desirable levels in all trials and β-carotene retentions after drying remained at satisfactory levels, fact that resulted in minimum value of 63% and approximately 94% in some cases. Vitamin C retention was comparatively more around 20-40% compared to control.

Evidence of tutoring in the development of subsong in newly-fledged Meyer's Parrots Poicephalus meyeri

Full Text Available Subsongs are vocal trials uttered by young birds to practice songs. Among songbirds, subsongs are displayed by individuals in their first year of life. Studies on Zebra Finches Poephila guttata suggest that the juveniles learn their songs from a vocal tutor, their father. In this study we examine the subsongs in six captive-born Meyer's Parrots Poicephalus meyeri, from fledging time to weaning. Recordings of songs from chicks and fathers were analyzed for similarities in frequency and time parameters. With age, the subsongs of the chicks became more similar to the vocalizations of the fathers with 20% similarity rating in the first week after fledging to 100% at weaning time. Moreover, fledged chicks were exposed to a wide range of stimuli from several species of parrots breeding pairs caged nearby but chicks exclusively learned their fathers' songs. Our data support the hypothesis that Meyer's Parrots are vocal learners and use their father as their tutor.Os ''subsongs'' são ensaios vocais emitidos pelas aves jovens para exercitar suas vozes. Nos pássaros canoros, ''subsongs'' são exibidos por indivíduos em seu primeiro ano de vida. Estudos com Poephila guttata sugerem que os jovens aprendem seus cantos de um tutor vocal, seu pai. Neste trabalho examinamos os ''subsongs'' em seis papagaios Poicephalus meyeri nascidos em cativeiro, desde a saída do ninho até a emancipação. Gravações dos cantos dos filhotes e dos pais foram analisadas para medir as similaridades nos parâmetros de freqüência e tempo. Com a idade, os ''subsongs'' dos filhotes viraram mais semelhantes às vocalizações dos pais, com 20% de similaridade na primeira semana após a saída do ninho até 100% na hora da emancipação. Ademais, os filhotes foram expostos a uma grande variedade de estímulos de várias outras espécies de papagaios nidificando em gaiolas vizinhas, mas eles aprenderam somente os cantos de seus pais.

Welfare Professions in Transition

Directory of Open Access Journals (Sweden)

2016-03-01

Full Text Available Welfare professions constitute one of the backbones in the development of the Nordic welfare states. Working in the public sector was for decades associated with high status; public sector employees were trusted employees. Through their work, they had important responsibilities for the welfare state and its citizens. To provide job security—through employment as officials—was a part of ensuring the stability of the state (Åkerstrøm, 2001, and we saw the establishment of what could be called a public ethos, a special morality aimed at serving the needs of the citizens and the state (Hoggett, 2005. The term welfare professions is widely used, referring to public sector employees in the field of, for example, health, education, care, and social work. So this term covers professionals who work directly in contact with patients, citizens, clients, students, etc. (Brante, 1990; Järvinen & Mik-Meyer, 2012. Along with the development and modernization of the welfare state, a number of new welfare professions, such as pedagogues, social works, physiotherapists, social care assistants, and auxiliary nurses have joined the existing ones like nurses, teachers, psychologists, and physicians. At the same time, however, the public sector has undergone dramatic changes as part of a neoliberal transformation of the welfare state. With the New Public Management (NPM wave from 1980s and onwards efforts to restructure public institutions and introduce market-like relationships between them, to outsource and privatize public services and to transform citizens to customers in a market have prevailed (Busch, 2005; Christensen & Lægreid, 2007; Greve, 2008. Within this reform strategy, welfare professionals are perceived as part of the problem that NPM is created to solve, namely an uncontrollable and wildly growing bureaucracy (Clarke & Newman, 1997 (...

2015-08-01

Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) is one of the most serious agricultural pests, feeding on a wide range of cultivated plants, including cotton, cereals and vegetables in the north of China. This insect can frequently switch between habitats and host plants over seasons and prefer plants in bloom. A. lucorum relies heavily on olfaction to locate its host plants finely discriminating different plant volatiles in the environment. Despite its economical importance, research on the olfactory system of this species has been so far very limited. In this study, we have identified and characterized an olfactory receptor which is sensitively tuned to (Z)-3-Hexenyl acetate and several flowering compounds. Besides being present in the bouquet of some flowers, these compounds are produced by plants that have suffered attacks and are supposed to act as chemical messengers between plants. This OR may play an important role in the selection of host plants. Copyright © 2015 Elsevier Ltd. All rights reserved.

Fugl-Meyer Assessment (FMA) is the most widely used and recommended clinical scale for evaluation of sensorimotor impairment post stroke, but an official Spanish version is not available today. This study aimed to establish methodological structure for translation and cultural adaptation process and perform a transcultural validation of the upper and lower extremity FMA to Colombian Spanish. Procedures included forward and backward translation, step-wise reviewing by bilingual and professional experts to ensure conceptual and semantic equivalence. Validation included a pilot evaluation of item-level agreement on 10 individuals with stroke at the Central Military Hospital of Colombia. Comprehensive step-wise procedure for transcultural validation was established. Low agreement (less than 70%) was detected for items assessing arm movements within synergies and for coordination/speed subscale. All points of disagreement were systematically reviewed and agreed upon when drafting the final version of the Spanish FMA. Use of FMA will allow unified description of stroke severity and motor recovery in Spanish speaking countries. This will open up possibility to compare stroke and rehabilitation outcomes with other countries and regions world-wide. Comprehensive methodological procedures provided can facilitate introduction of well-established clinical scales in other languages. Implications for Rehabilitation The Fugl-Meyer Assessment (FMA) of upper and lower extremity is the most used and recommended clinical scale for evaluation of sensorimotor impairment after stroke. The Spanish version of FMA, validated in this study, is now first time available for use in research and clinical practice. Use of FMA will allow unified description of stroke severity and motor recovery in Spanish speaking countries, which in turn opens up possibility to compare stroke and rehabilitation outcomes with other countries and regions world-wide.

To assess the therapeutic effect of Jin's "Sanzhen" therapy combined with rehabilitation training on limb-motor function of stroke patients by using Fugl-Meyer scale. A total of 254 hemiplegic stroke outpatients and inpatients from 7 hospitals were randomly divided into Jin's "Sanzhen" (JSZ) group (n = 83), rehabilitation group (n = 84) and combination group (n = 87). Acupuncture was applied to acupoints of Jin's "Sanzhen" including Quchi (LI 11), Waiguan (SJ 5) and Hegu (LI 4); Futu (ST 32). Zusanli (ST 36) and Sanyinjiao (SP 6); etc. The acupuncture needles were retained for 30 min after "Deqi". Rehabilitation training included passive joint movement, standing-sitting training, tapping-pressing stimulation, walking training, etc. The treatment was conducted once daily, 5 sessions a week and for 4 weeks. Fugl-Meyer scale composed of 100-point motor domain of the upper- and lower-extremity sections was used to assess the patients' motor function. On day 28 after the treatment, of the 83.84 and 87 hemiplegic stroke patients in the JSZ, rehabilitation and combination groups, 48 (57.8%), 31 (36.9%) and 50 (57.5%) experienced marked improvement in their clinical symptoms and signs, 26 (31.3%), 44 (52.4%) and 31(35.6%) had an improvement, and 9 (10.8%), 9 (10.7%) and 6 (6.9%) failed in the treatment, with the total effective rates being 89.2%, 89.3% and 93.1%, respectively. The neurological deficit score (NDS) of the combination group was significantly lower than that of the rehabilitation group (P rehabilitation groups (P rehabilitation groups in both NDS and FMAS (P > 0.05). Jin's "Sanzhen" therapy combined with rehabilitation training can significantly improve the limb motor function of hemiplegic stroke patients, and has a good synergistic effect.

Working in the Public Sector. Introduction to the Thematic Issue

Directory of Open Access Journals (Sweden)

Annette Kamp

2013-05-01

Full Text Available Work in the public sector has been changing dramatically in recent decades. Reforms aimed at increasing the efficiency of public services have been extensive in the Nordic countries and elsewhere since the 1980s. The reforms and changes have to a large extent been associated with so-called New Public Management (NPM principles, emphasizing the market as a central coordination mechanism. Consequently, public institutions have been restructured, their services are standardized and commodified, and market-like relationships between them have been created. In order to create markets and transform citizens into customers on a market, outsourcing and privatization have been stimulated (Blomqvist & Rothstein 2000, Busch et al 2005, Christensen & Lægreid 2007, Greve 2003. At the same time, traditional Weberian bureaucratic principles are still viable and even enhanced within the sector, for instance, as a consequence of the use of contracts as a means of managing public organizations (Greve 2008. Lately, large reforms aimed at centralized coordination of different service providers, such as the integration of the Norwegian welfare administration, have been labeled post-NPM reforms by some researchers. The implication of all these parallel tendencies is that the institutional and organizational landscape surrounding the work situations of employees in the public sector have become increasingly complex, some call them hybrid,  putting a variety of conflicting pressures on the performance of work within the sector (Christensen & Lægreid 2011, Hasselbladh et al. 2008. In this special issue, we explore some of the consequences of these structural and normative changes on the work of public sector employees in different sectors and contexts (...

Meyer-Overton reforged: The origins of alcohol and anesthetic potency in membranes as determined by a new NMR partitioning probe, benzyl alcohol

Energy Technology Data Exchange (ETDEWEB)

Janes, N.; Ma, L.; Hsu, J.W.; Rubin, E.; Taraschi, T.F. (Thomas Jefferson Univ., Philadelphia, PA (United States))

1992-01-01

The Meyer-Overton hypothesis--that anesthesia arises from the nonspecific action of solutes on membrane lipids--is reformulated using colligative thermodynamics. Configurational entropy, the randomness imparted by the solute through the partitioning process, is implicated as the energetic driving force that pertubs cooperative membrane equilibria. A proton NMR partitioning approach based on the anesthetic benzyl alcohol is developed to assess the reformulation. Ring resonances from the partitioned drug are shielded by 0.2 ppm and resolved from the free, aqueous drug. Free alcohol is quantitated in dilute lipid dispersions using an acetate internal standard. Cooperative equilibria in model dipalmitoyl lecithin membranes are examined with changes in temperature and alcohol concentration. The L[sub [beta][prime

Full Text Available Öz Toplu iş uyuşmazlıklarında önemli bir mücadele aracı olan grev hakkı sendika özgürlüğünün ayrılmaz bir parçasıdır ve bu hakkın kullanımı hukukumuzda sıkı usul kurallarına bağlanmıştır. Bu sıkı kurallar yanında grev hakkını sınırlandıran bir başka unsur, idari kararla grevi erteleme yetkisinin idareye tanınmış olmasıdır. Türk hukukunda bu yetki Bakanlar Kuruluna aittir. Bakanlar Kurulu kendi takdiri çerçevesinde karar alınmış ya da başlanmış olan bir grevin genel sağlık ve/veya milli güvenlik üzerinde tehdit oluşturduğu gerekçesiyle ertelenmesine karar verebilir. Erteleme kavramının anlamı gereği bu idari kararın grevi geçici bir süre ile durduracağı düşünülebilir. Aslında tam tersine altmış günlük erteleme süresi sonunda taraflar arasında bir anlaşmaya varılamamışsa grev hakkı kalıcı bir sınırlama ile karşı karşıya kalmaktadır. İdarenin uygulamada somut olayın özelliklerini dikkate almadan sıklıkla başvurduğu bu yöntem nedeniyle, grev hakkının özüne dokunacak şekilde hukuka aykırı müdahaleler gerçekleşmektedir. Abstract The right to strike, which is a substantial instrument to help struggling in collective labour conflicts, is an integral part of the freedom of association and the exercise of this right has been bound to strict rules of procedure in our law system. In addition to these strict rules, the power of the administration to postpone strikes by an administrative decision is an another restrictive factor on the right to strike. This authority belongs to the Council of Ministers in Turkish law. According to his appreciation, the Council of Ministers can decide to postpone a legal strike which has been called or commenced on the grounds that the strike is threatening public health or national security. Due to the notion of postponement, it is likely to suppose that this administrative decision will suspend strike actions temporarily. Actually in contrast, the right to strike is confronted with a permanent limitation if there is not an agreement between the parties at the end of the sixty-day suspension period. Because of the fact that the administration has frequently invoked this procedure in practice without taking into consideration the circumstances of the present case, interferences often occur in such a way that the core of the right is breached.

Stworzenie świata według Leibniza

Directory of Open Access Journals (Sweden)

Michał Heller

2008-06-01

Full Text Available Leibniz's idea of creation is best epitomized by a note written by him on the margin of his work entitled 'Dialogus'. The note reads:'When God thinks things through and calculates, the world is made'. Simple calculations are almost mechanical. The true mathematical thinking begins when one is confronted with a problem that has to be solved, when starting from the known mathematical structure one has to construct a new structure, to comprehend its intricacies, the ways of its functioning, and its connections with other mathematical structures. And when one successfully applies the new mathematical structure to a physical theory, the new world is made. This was Leibniz's experience when he was discovering calculus and tried to apply it to mechanical problems. Leibniz's doctrine that our world is the best of all possible words is often ridiculed, but this attitude is the result of a very superficial reading of Leibniz's texts. In fact, God's calculations to choose the best possible world are similar to solving the variational problem in mathematics. Leibniz claims that in mathematical reasoning if there is neither 'maximum' nor 'minimum' nothing can happen. Similarly, if there were no world better that other possible worlds, God's wisdom would have not been able to create anything. Some consequences of this doctrine, concerning the nature of space, time and causality, are also considered.

Preference of a polyphagous mirid bug, Apolygus lucorum (Meyer-Dür for flowering host plants.

Directory of Open Access Journals (Sweden)

Hongsheng Pan

Full Text Available Apolygus lucorum (Meyer-Dür (Hemiptera: Miridae is one of the most important herbivores in a broad range of cultivated plants, including cotton, cereals, vegetables, and fruit crops in China. In this manuscript, we report on a 6-year long study in which (adult A. lucorum abundance was recorded on 174 plant species from 39 families from early July to mid-September. Through the study period per year, the proportion of flowering plants exploited by adult A. lucorum was significantly greater than that of non-flowering plants. For a given plant species, A. lucorum adults reached peak abundance at the flowering stage, when the plant had the greatest attraction to the adults. More specifically, mean adult abundance on 26 species of major host plants and their relative standard attraction were 10.3-28.9 times and 9.3-19.5 times higher at flowering stage than during non-flowering periods, respectively. Among all the tested species, A. lucorum adults switched food plants according to the succession of flowering plant species. In early July, A. lucorum adults preferred some plant species in bloom, such as Vigna radiata, Gossypium hirsutum, Helianthus annuus and Chrysanthemum coronarium; since late July, adults dispersed into other flowering hosts (e.g. Ricinus communis, Impatiens balsamina, Humulus scandens, Ocimum basilicum, Agastache rugosus and Coriandrum sativum; in early September, they largely migrated to flowering Artemisia spp. (e.g. A. argyi, A. lavandulaefolia, A. annua and A. scoparia. Our findings underscore the important role of flowering plays in the population dynamics and inter-plant migration of this mirid bug. Also, our work helps understand evolutionary aspects of host plant use in polyphagous insects such as A. lucorum, and provides baseline information for the development of sustainable management strategies of this key agricultural pest.

Recently, the reliability of the Brazilian version of the Fugl-Meyer Assessment (FMA) was assessed through the scoring given according to observations made by a single evaluator who applied the test. When different raters apply the scale, the reliability may depend on the interpretation given to the assessment sheet. In such cases, a clear administration manual is essential for ensuring homogeneity of application. To translate and adapt the French Canadian version of the FMA administration manual into Brazilian Portuguese and to evaluate the inter-rater reliability when different evaluators apply the FMA on the basis of the information contained in the manual. Eighteen adults (59±10 years) with chronic hemiparesis (38±35 months after a stroke) took part in this study. Eight patients participated in the first part of the study and 10 in the second part. Based on analyzing the results from part 1, an adapted version was developed, in which information and photos were added to illustrate the positions of the patient and evaluator. The inter-rater reliability was assessed using the intraclass correlation coefficient (ICC). The reliability of the FMA based on the adapted version of the manual was excellent for the total motor scores for the upper limbs (ICC=0.98) and lower limbs (ICC=0.90), as well as for movement sense (ICC=0.98) and upper and lower-limb passive range of motion (ICC=0.84 and 0.90, respectively). The reliability was moderate for tactile sensitivity (0.75). The joint pain assessment presented low reliability. The results showed that, except for pain assessment, application of the FMA based on the adapted version of the application manual for Brazilian Portuguese presented adequate inter-rater reliability.

LITOS – a new balloon-borne instrument for fine-scale turbulence soundings in the stratosphere

2011-01-01

Full Text Available We have developed a new compact balloon payload called LITOS (Leibniz-Institute Turbulence Observations in the Stratosphere for high resolution wind turbulence soundings in the stratosphere up to 35 km altitude. The wind measurements are performed using a constant temperature anemometer (CTA with a vertical resolution of ~2.5 mm, i.e. 2 kHz sampling rate at 5 m/s ascent speed. Thereby, for the first time, it is possible to study the entire turbulence spectrum down to the viscous subrange in the stratosphere. Including telemetry, housekeeping, batteries and recovery unit, the payload weighs less than 5 kg and can be launched from any radiosonde station. Since autumn 2007, LITOS has been successfully launched several times from the Leibniz-Institute of Atmospheric Physics (IAP in Kühlungsborn, Germany (54° N, 12° E. Two additional soundings were carried out in 2008 and 2009 in Kiruna, Sweden (67° N, 21° E as part of the BEXUS program (Balloon-borne EXperiments for University Students. We describe here the basic principle of CTA measurements and prove the validity of this method in the stratosphere. A first case study allows a clear distinction between non-turbulent regions and a turbulent layer with a thickness of some tens of meters. Since our measurements cover the transition between the inertial and viscous subrange, energy dissipation rates can be calculated with high reliability.

Due to stricter efficiency legislation for electrical machines, it becomes increasingly important to predict a motor's performance with regard to start and operational behaviour correctly. In consequence of the higher efficiency required for electrical machines, permanent magnet synchronous machines become an interesting alternative also for motors with direct on-line starting.

As one of the eight large research museums in the Federal Republic of Germany and as a member of the Leibniz Society (Bonn, Federal Republic of Germany), the German mining industry museum Bochum understands its special exhibitions as a result of a large-scale research project. Contrary to other institutions for science, the research museums use the chance to publish their research results in the sense of 'Public Understanding of Science' to the broad public. To this extent, research museums have an important educational function for our modern society.

Full Text Available The green plant bug (Apolygus lucorum Meyer-Dür is a key pest of Bt cotton in China. Along with biological control, chemical control is one of the most important strategies in A. lucorum Integrated Pest Management (IPM. The goal of this study was to evaluate the toxicity of eight conventional insecticides to A. lucorum and to assess the susceptibility of two generalist predators Chrysopa sinica (Jieder and Propylaea japonica (Thunbery to insecticides that are commonly used in A. lucorum management. Via glass-vial and leaf-dip bioassay, toxicity tests with selected insecticides at two different life-stages of A. lucorum indicated significant differences between the LD50 or LC50 values for these compounds within different insecticidal classes. Phenylpyrazole fipronil had the highest toxicity to 4th-instar nymphs and adults of A. lucorum, whereas neonicotinoid imidacloprid had the lowest toxicity among the insecticides. Females were more tolerant to insecticides than were males, as shown by the higher LD50 values for females. Furthermore, laboratory tests showed that endosulfan had the highest selectivity to C. sinica and P. japonica: the selective toxicity ratios (STRs were superior to other tested insecticides, particularly imidacloprid, and were 5.396 and 4.749-fold higher than baseline STRs, respectively. From this study, we conclude that fipronil can potentially be used to efficiently control A. lucorum. An alternative control agent worth consideration is endosulfan, owing to its relative safety to non-targeted natural enemies.

Los Nuevos Ensayos. Ensayo de un diálogo pretendido

2009-11-01

Full Text Available La lectura de los Nuevos Ensayos sobre el Entendimiento Humano de Leibniz supone el encuentro con una obra de madurez, redactada entre el verano de 1703 y enero de 1704. A estas alturas de su vida, Leibniz tiene plenamente desarrollado su sistema, y, sin embargo, sorprende que esta obra no sea una exposición sistemática de su pensamiento. La sorpresa procede, en primer lugar, de su estructura y articulación, y, en segundo lugar, de la finalidad de su escritura. Los Nuevos Ensayos no transcriben el sistema de Leibniz en su orden estructural, sino siguiendo el orden expositivo del Ensayo sobre el Entendimieto Humano de Locke. Así pues, los Nuevos Ensayos, siguiendo la obra de Locke, además del Prefacio, está dividida en cuatro libros, dedicados respectivamente al estudio del problema de lo innato, las ideas, el lenguaje y el conocimiento. La propia estructura delata claramente lo que en el Prefacio confiesa Leibniz: beneficiarse del trabajo ajeno, y no sólo para disminuir el propio, sino sobre todo para aportar algo a lo ya escrito por aquél, lo cual siempre es más fácil que empezar desde el principio, además de beneficiarse de su reputación; era, según Leibniz, una buena ocasión para publicar algo bajo el título de Nuevos Ensayos sobre el Entendimiento Humano, consiguiendo así una acogida favorable para sus pensamientos, el ponerlos en tan buena compañía.

Upper Extremity Functional Evaluation by Fugl-Meyer Assessment Scoring Using Depth-Sensing Camera in Hemiplegic Stroke Patients.

Directory of Open Access Journals (Sweden)

Won-Seok Kim

Full Text Available Virtual home-based rehabilitation is an emerging area in stroke rehabilitation. Functional assessment tools are essential to monitor recovery and provide current function-based rehabilitation. We developed the Fugl-Meyer Assessment (FMA tool using Kinect (Microsoft, USA and validated it for hemiplegic stroke patients. Forty-one patients with hemiplegic stroke were enrolled. Thirteen of 33 items were selected for upper extremity motor FMA. One occupational therapist assessed the motor FMA while recording upper extremity motion with Kinect. FMA score was calculated using principal component analysis and artificial neural network learning from the saved motion data. The degree of jerky motion was also transformed to jerky scores. Prediction accuracy for each of the 13 items and correlations between real FMA scores and scores using Kinect were analyzed. Prediction accuracies ranged from 65% to 87% in each item and exceeded 70% for 9 items. Correlations were high for the summed score for the 13 items between real FMA scores and scores obtained using Kinect (Pearson's correlation coefficient = 0.873, P<0.0001 and those between total upper extremity scores (66 in full score and scores using Kinect (26 in full score (Pearson's correlation coefficient = 0.799, P<0.0001. Log transformed jerky scores were significantly higher in the hemiplegic side (1.81 ± 0.76 compared to non-hemiplegic side (1.21 ± 0.43 and showed significant negative correlations with Brunnstrom stage (3 to 6; Spearman correlation coefficient = -0.387, P = 0.046. FMA using Kinect is a valid way to assess upper extremity function and can provide additional results for movement quality in stroke patients. This may be useful in the setting of unsupervised home-based rehabilitation.

The frequencies of {gamma}-ray-induced micronuclei (MN) in Cytokinesis-Blocked (CB) lymphocytes at several doses were measured in three donors of human and C57BL/6 mice. Measurements performed after irradiation showed a dose-related increases in MN frequency in each of the donors studied. The relative sensitivity of mouse in Spleen Lymphocytes (SLs) compared with human Peripheral Blood Lymphocytes (PBLs) was estimated by best fitting linear-quadratic model based on the radiation-induced MN data over the range from 0 cGy to 400 cGy. In the case of MN frequency with 0.2 per CB cell, the relative sensitivity of mouse SLs was 1.67. Compared with the radiation-induced MN formation in the PBLs of human, the SLs of mouse were more radiosensitive. Using this MN assay with human PBLs and mouse SLs, studies were performed to determine whether the water fraction of ginseng (Panax ginseng C.A.Meyer)against radiation-induced MN in human PBLs after in vitro irradiation (3Gy) and in SLs of C57BL/6 mice after in vivo irradiation (3Gy). The frequency of MN in human PBLs was reduced by water fraction of ginseng (0.5mg/ml of medium) both pre-and post treatment (p<0.01) in vitro. In addition, the frequency of MN in mouse SLs was also reduced by pretreatment of ginseng (2mg/ml of drinking water for 7 days) in vivo.

There are many places in Germany where deep geothermal energy is available as an environmentally friendly alternative to fossil fuels as a source of power and heat. When it comes to utilising this energy, drilling is the most expensive part. Power and heat generation is only cost-effective if sufficiently high water temperatures and flow rates are found. Via GeotIS, an online information system, planners can now gain fast access to geological and geophysical data for Germany. (orig.)

Treatment of the N-thiophosphorylated iminophosphorane ligands (PTA)═NP(═S)(OR)2 [PTA = 1,3,5-triaza-7-phosphaadamantane, 3a and 3b] and (DAPTA)═NP(═S)(OR)2 [DAPTA = 3,7-diacetyl-1,3,7-triaza-5-bicyclo[3.3.1]nonane, 4a and 4b] with an equimolecular amount of AgSbF6 leads to high-yield formation of the new one-dimensional coordination polymers [Ag{μ(2)-N,S-(PTA)═NP(═S)(OR)2}]x[SbF6]x (5a and 5b) and [Ag{μ(2)-O,S-(DAPTA)═NP(═S)(OR)2}]x[SbF6]x (6a and 6b), respectively. These new (iminophosphorane)silver(I) coordination polymers are efficient catalyst precursors for the Meyer-Schuster isomerization of both terminal and internal alkynols. Reactions proceeded in water, under aerobic conditions and using microwave irradiation as heating source, to afford the corresponding α,β-unsaturated carbonyl compounds in excellent yields, without the addition of any cocatalyst. Remarkably, it should be noted that this catalytic system can be recycled up to 10 consecutive runs (1st cycle 45 min, 99%; 10th cycle 6 h, 97%). ESI-MS analysis of 5a in water has been carried out providing valuable insight into the monomeric active species responsible for catalytic activity in water.

Evolution, functional differentiation, and co-expression of the RLK gene family revealed in Jilin ginseng, Panax ginseng C.A. Meyer.

Most genes in a genome exist in the form of a gene family; therefore, it is necessary to have knowledge of how a gene family functions to comprehensively understand organismal biology. The receptor-like kinase (RLK)-encoding gene family is one of the most important gene families in plants. It plays important roles in biotic and abiotic stress tolerances, and growth and development. However, little is known about the functional differentiation and relationships among the gene members within a gene family in plants. This study has isolated 563 RLK genes (designated as PgRLK genes) expressed in Jilin ginseng (Panax ginseng C.A. Meyer), investigated their evolution, and deciphered their functional diversification and relationships. The PgRLK gene family is highly diverged and formed into eight types. The LRR type is the earliest and most prevalent, while only the Lec type originated after P. ginseng evolved. Furthermore, although the members of the PgRLK gene family all encode receptor-like protein kinases and share conservative domains, they are functionally very diverse, participating in numerous biological processes. The expressions of different members of the PgRLK gene family are extremely variable within a tissue, at a developmental stage and in the same cultivar, but most of the genes tend to express correlatively, forming a co-expression network. These results not only provide a deeper and comprehensive understanding of the evolution, functional differentiation and correlation of a gene family in plants, but also an RLK genic resource useful for enhanced ginseng genetic improvement.

This paper gives an update on the design and developments of the new scanning Doppler iron temperature lidar. Continuous temperature profiles in the altitude range from 50 to 105 km are derived by using the iron resonance and Rayleigh backscatter signal of this lidar. We show a common volume measurement with the well established potassium and Rayleigh-Mie-Raman (RMR) lidar at the Leibniz-Institute of Atmospheric Physics (IAP) in Kühlungsborn (Germany, 54°N). The iron lidar temperatures match quite well and have an uncertainty of 0.4K at the top of the iron layer. Improvements for daylight capability are under development and will be pointed out.

Approaches to Identification of Institutions in Institutional Economics

Directory of Open Access Journals (Sweden)

Igor M. Shiriaev

2017-03-01

Full Text Available The paper deals with the methodology for identification of institutions from institutional economics perspective. The differences between the perspectives provided by old and new institutional economics are highlighted. These differences are interpreted in the context of compared pragmatist and postpositivist methodologies. This paper applies to the post-positivist approach to the identification of institutions. One example of institution is provided by power-property institution. Identification of this institution in the historical and economic research is based on several theoretical generalizations and supported by array of historical facts. Another example is provided by identification of institution and institutional change in higher education based on discourse analysis and interviews with the main actors. In this paper, the regulatory institutions of higher education are analyzed as well. The concept of power-property institution is extended to the higher education by proposing hypotheses on the functioning of state governing-regulating institution in this sphere. This institution prescribes the actors to behave in accordance with the objectives of public policy, which can only be implemented in the form of bureaucratization of higher education. The paper describes the behavioral regularity generated by an identified institution. Functioning of the governing-regulating institution in higher education is illustrated by examples of behavioral regularities emerging from activities in accordance with this institution. The paper also shows the possibility of falsification of proposed hypothesis.

Psychometrics of the wrist stability and hand mobility subscales of the Fugl-Meyer assessment in moderately impaired stroke.

Page, Stephen J; Hade, Erinn; Persch, Andrew

2015-01-01

There remains a need for a quickly administered, stroke-specific, bedside measure of active wrist and finger movement for the expanding stroke population. The wrist stability and hand mobility scales of the upper extremity Fugl-Meyer Assessment (w/h UE FM) constitute a valid, reliable measure of paretic UE impairment in patients with active wrist and finger movement. The aim of this study was to determine performance on the w/h UE FM in a stable cohort of survivors of stroke with only palpable movement in their paretic wrist flexors. A single-center cohort study was conducted. Thirty-two individuals exhibiting stable, moderate upper extremity hemiparesis (15 male, 17 female; mean age=56.6 years, SD=10.1; mean time since stroke=4.6 years, SD=5.8) participated in the study, which was conducted at an outpatient rehabilitation clinic in the midwestern United States. The w/h UE FM and Action Research Arm Test (ARAT) were administered twice. Intraclass correlation coefficients (ICCs), Cronbach alpha, and ordinal alpha were computed to determine reliability, and Spearman rank correlation coefficients and Bland-Altman plots were computed to establish validity. Intraclass correlation coefficients for the w/h UE FM and ARAT were .95 and .99, respectively. The w/h UE FM intrarater reliability and internal consistency were greater than .80, and concurrent validity was greater than .70. This also was the first stroke rehabilitative study to apply ordinal alpha to examine internal consistency values, revealing w/h UE FM levels greater than .85. Concurrent validity findings were corroborated by Bland-Altman plots. It appears that the w/h UE FM is a promising tool to measure distal upper extremity movement in patients with little active paretic wrist and finger movement. This finding widens the segment of patients on whom the w/h UE FM can be effectively used and addresses a gap, as commonly used measures necessitate active distal upper extremity movement. © 2015 American

Electrical double-layer capacitors, also known as supercapacitors (SC) are devices for electrical energy storage used for fast acceleration of hybrid cars or for the energy recovery during breaking operations. In contrast, lithium-ion batteries (LIB) are used as energy storage devices to provide an extended travel distance for plug-in hybrid cars and electric vehicles. Current research aims to overcome the major limitations of both technologies (SC: low energy density/LIB: slow recharge and limited service life) and hybrid cells are considered a promising solution. The goal is to improve the performance and energy density of storage devices which can be achieved, as shown by the Leibniz-Institute for New Materials (INM), with the use of nanotechnology. (orig.)

Twisted supersymmetry: Twisted symmetry versus renormalizability

International Nuclear Information System (INIS)

Dimitrijevic, Marija; Nikolic, Biljana; Radovanovic, Voja

2011-01-01

We discuss a deformation of superspace based on a Hermitian twist. The twist implies a *-product that is noncommutative, Hermitian and finite when expanded in a power series of the deformation parameter. The Leibniz rule for the twisted supersymmetry transformations is deformed. A minimal deformation of the Wess-Zumino action is proposed and its renormalizability properties are discussed. There is no tadpole contribution, but the two-point function diverges. We speculate that the deformed Leibniz rule, or more generally the twisted symmetry, interferes with renormalizability properties of the model. We discuss different possibilities to render a renormalizable model.

Full Text Available The medicinal plants Panax ginseng C. A. Meyer (Araliaceae and Heteropterys tomentosa A. Juss (Malpighiaceae are widely and separately used by the Brazilian population as phytotherapeutics for the same medicinal purposes as tonics and to improve cognition. A chemical analysis was carried out on hydroethanolic extracts of powdered roots from P. ginseng and H. tomentosa using HPLC-DAD-ESI-MS/MS (High Performance Liquid Chromatography coupled to Diode-Array Detector and Electrospray Ionization - Mass Spectrum/Mass Spectrum. The ginsenosides Rg1, Rf, mRg and mRf were the main constituents in a hydroethanolic extract from P. ginseng, while in the hydroethanolic extract from H. tomentosa, caffeoylquinic acid derivatives and astilbin isomers were the main constituents. Concentration-time-effect curves were generated in cultures of astrocytes that were incubated with hydroethanolic extracts of these species to elucidate their toxicities. The P. ginseng extract was nontoxic at all of the tested times and concentrations. The hydroethanolic extract from H. tomentosa demonstrated toxicity at a concentration of 1000 µg/mL. P. ginseng extract had no protective effect against staurosporine. Many studies have demonstrated the neuroprotective effect of ginsenosides, caffeoylquinic derivatives and flavonoids.

Evolutionary institutionalism.

Science.gov (United States)

Fürstenberg, Dr Kai

Institutions are hard to define and hard to study. Long prominent in political science have been two theories: Rational Choice Institutionalism (RCI) and Historical Institutionalism (HI). Arising from the life sciences is now a third: Evolutionary Institutionalism (EI). Comparative strengths and weaknesses of these three theories warrant review, and the value-to-be-added by expanding the third beyond Darwinian evolutionary theory deserves consideration. Should evolutionary institutionalism expand to accommodate new understanding in ecology, such as might apply to the emergence of stability, and in genetics, such as might apply to political behavior? Core arguments are reviewed for each theory with more detailed exposition of the third, EI. Particular attention is paid to EI's gene-institution analogy; to variation, selection, and retention of institutional traits; to endogeneity and exogeneity; to agency and structure; and to ecosystem effects, institutional stability, and empirical limitations in behavioral genetics. RCI, HI, and EI are distinct but complementary. Institutional change, while amenable to rational-choice analysis and, retrospectively, to criticaljuncture and path-dependency analysis, is also, and importantly, ecological. Stability, like change, is an emergent property of institutions, which tend to stabilize after change in a manner analogous to allopatric speciation. EI is more than metaphorically biological in that institutional behaviors are driven by human behaviors whose evolution long preceded the appearance of institutions themselves.

Institutional entrepreneurship pays specific attention to the process and outcomes of agents who are willing and capable of changing institutions. It has some common ground with the political entrepreneur, a concept that proposes change in norms and institutions because of commitment and activities...... of agents or organisations in the policy arena. The present chapter understands institutional entrepreneurship as the process of changing institutionalised practices. Based on a literature review, it describes the triggers, activities and potential effects of institutional entrepreneurs.

Background The study of phenolic compounds profiles and antioxidative activity in ginseng fruit, leaves, and roots with respect to cultivation years, and has been little reported to date. Hence, this study examined the phenolic compounds profiles and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free-radical-scavenging activities in the fruit, leaves, and roots of Korean ginseng (Panax ginseng Meyer) as a function of cultivation year. Methods Profiling of 23 phenolic compounds in ginseng fruit, leaves, and roots was investigated using ultra-high performance liquid chromatography with the external calibration method. Antioxidative activity of ginseng fruit, leaves, and roots were evaluated using the method of DPPH free-radical-scavenging activity. Results The total phenol content in ginseng fruit and leaves was higher than in ginseng roots (p phenol content in the ginseng samples was significantly correlated to the DPPH free-radical-scavenging activity (r = 0.928****). In particular, p-coumaric acid (r = 0.847****) and ferulic acid (r = 0.742****) greatly affected the DPPH activity. Among the 23 phenolic compounds studied, phenolic acids were more abundant in ginseng fruit, leaves, and roots than the flavonoids and other compounds (p phenolic compounds in 3–6-yr-old ginseng fruit, leaves, and roots. Conclusion This study provides basic information about the antioxidative activity and phenolic compounds profiles in fruit, leaves, and roots of Korean ginseng with cultivation years. This information is potentially useful to ginseng growers and industries involved in the production of high-quality and nutritional ginseng products. PMID:26843824

The Leibniz Institute for Applied Geosciences (GGA-Institut) is setting up an internet based information system on geothermal resources in close collaboration with partners. For a start, the geothermal information system will contain data about hydrogeothermal resources only. The project aims at an improvement of quality in the planning of geothermal plants and at a minimization of exploration risks. The key parameters for this purpose are production rate (Q) and temperature (T). The basis for the estimation of subsurface hydraulic properties comes from the information system on hydrocarbons. This information system provides permeability and porosity values derived from the analyses of drilling cores. The IT targets will be realised by a relational database providing all data relevant to the project. A 3D model of the ground provides the basis for visualisation and calculation of geothermal resources. As a prototype, a data-recall facility of geothermal sites in Germany is available online.

This thesis under the titel Experimental Determination of the Electronic Properties of Application-relevant Interfaces of Organic Semiconductors by means of Photoelectron Spectroscopy was drawn up at the Leibniz Institute for Solid-State and Materials Research (IFW) Dresden at the Institute for Solid-State Research (IFF) under the maintenance of Prof. Dr. B. Buechner. To the scientific study hereby came two types of application-relevant interfaces. On the one hand the influence of the electrode preparation under normal conditions by means of ex-situ purification procedures in comparison to in-situ prepared contacts on the electronic behaviour of the organic semiconductor sexithiophene on interfaces to metallic substrates was studied. As substrate materials hereby the metals silver, palladium, gold, and platinum came to application. In a second study the interfaces of the organic semiconductors sexithiophene and copper(II)-phthalocyanine in contact to thin films of the transition-metal oxide La{sub 0.7}Sr{sub 0.3}MnO{sub 3} were studied. Also here a comparing study for ex-situ and in-situ purificated La{sub 0.7}Sr{sub 0.3}MnO{sub 3} contacts was performed. The films applied for this were fabricated in the IWF Dresden at the Institute for Metallic Materials (IMW). Also in the framework of these studies the influence of oxygen on the electronic and chemical behaviour on the interfaces held the spotlight.

Profilicollis chasmagnathi Holcman-Spector, Mañé-Garzón & Dei-Cas, 1977 (Acanthocephala: Polymorphidae) has been reported to parasitise different grapsid species as intermediate hosts along the South Atlantic shores, i.e. Cyrtograpsus angulatus (Dana) and Neohelice granulata (Dana) in Uruguay and Cyrtograpsus altimanus (Rathbun) in Argentina. Larvae of a similar acanthocephalan described as Profilicollis antarcticus Zdzitowiecki, 1985 were recorded in the crab Hemigrapsus crenulatus (Milne-Edwards) from an estuarine habitat on the Southeast Pacific shore in Chile. Earlier studies have questioned the specific assignation of the Chilean estuarine populations of Profilicollis Meyer, 1931. The aim of this study was to re-examine the identification of these acanthocephalans by means of morphological and molecular analyses of cystacanths of Profilicollis spp. gathered from C. angulatus, N. granulata, C. altimanus and H. crenulatus. Our analyses showed that a single species of Profilicollis, P. chasmagnathi, parasitises these four crab species. The assessment of specimens from the South Shetlands Islands, the type-locality of P. antarcticus, is needed before formally proposing that P. antarcticus is a junior subjective synonym of P. chasmagnathi.

Informal institutions and radical ideologies under institutional transformation

Irina Starodubrovskaya

2015-06-01

Full Text Available This article questions one of the central postulates of institutional economic theory, i.e., that of the sustainability and purely evolutionary changes of informal institutions. To study the phenomenon of the destruction of informal institutions and its consequences, we use the tools of sociological theory, which acknowledge that a period of intensive urbanization is characterized by anomie, i.e., a lack of norms, in which traditional institutions are destroyed, while new urban institutions have not yet taken shape. We reviewed the possible reactions of communities and individuals to the conditions of anomie, including the compensatory mechanisms of ideologies. In the case of the Dagestan Republic, we show how the proliferation of fundamentalist Islamic ideology is associated with the state of anomie and the consequences to which it could lead from an institutional point of view. The analysis of the situation in Dagestan is based on long-term field research conducted in the region.
