Full Text Available Frente al desafío de avanzar hacia un modelo de desarrollo sustentado en la innovación, el conocimiento y el aprendizaje por interacción se han transformado en los pilares fundamentales del crecimiento. Bajo este argumento, se acepta que los mecanismos que promueven la asociación entre quienes producen el conocimiento y quienes se benefician con su utilización, constituyen uno de los mejores pactos para vincular los procesos y dinámicas de aprendizaje con el desarrollo económico y social. En Argentina, la Ley 23.877 del año 1990 dispuso la creación de las Unidades de Vinculación Tecnológica (UVT, definiéndolas como estructuras de interfase entre el sector productivo y el sistema científico técnico y universitario. Sin embargo, los diagnósticos vigentes señalan que la actividad de transferencia tecnológica encomendada a las UVTs sigue siendo una asignatura pendiente. La propuesta de este trabajo es analizar en profundidad estos diagnósticos disponibles y ofrecer una serie de argumentos a partir de los cuales es posible afirmar que las UVTs no han logrado aún una dinámica de interacción adecuada entre el Sector Científico Tecnológico y el sector productivo, que contribuya a la promoción de niveles sistémicos óptimos para la modernización y actualización tecnológica de la estructura productiva.

A scaling at pilot plant level was performanced for the treatment of wastes are stored in significant quantities at the Instituto Tecnologico de Costa Rica (ITCR). These wastes are aqueous of heavy metals from laboratories and of the nitriding process slag. Dr. Katsuhiro Harada, Japanese aid worker, suggested a treatment methodology that was tested and adapted to the characteristics of hazardous wastes generated in the ITCR. In addition, an operating procedure was suggested to centralize the treatment of waste produced in different labs but they have similar chemical characteristics; therefore can be treated with the same chemical method. For these cases it is easier and cheaper to concentrate the treatment in one place, and in the case of extremely hazardous waste, whose treatment and disposal are somewhat complicated to implement, it is advisable to establish a specialized laboratory with trained personnel for management. A hazardous waste laboratory equipped with a reactor, sludge filter and laboratory equipment for analysis. The methods tested in the pilot plant for the treatment of aqueous wastes of heavy metals and cyanide slag were effective. (author) [es

Magnetostatic modes in ferromagnetic samples with inhomogeneous internal fields

Science.gov (United States)

Arias, Rodrigo

2015-03-01

Magnetostatic modes in ferromagnetic samples are very well characterized and understood in samples with uniform internal magnetic fields. More recently interest has shifted to the study of magnetization modes in ferromagnetic samples with inhomogeneous internal fields. The present work shows that under the magnetostatic approximation and for samples of arbitrary shape and/or arbitrary inhomogeneous internal magnetic fields the modes can be classified as elliptic or hyperbolic, and their associated frequency spectrum can be delimited. This results from the analysis of the character of the second order partial differential equation for the magnetostatic potential under these general conditions. In general, a sample with an inhomogeneous internal field and at a given frequency, may have regions of elliptic and hyperbolic character separated by a boundary. In the elliptic regions the magnetostatic modes have a smooth monotonic character (generally decaying form the surfaces (a ``tunneling'' behavior)) and in hyperbolic regions an oscillatory wave-like character. A simple local criterion distinguishes hyperbolic from elliptic regions: the sign of a susceptibility parameter. This study shows that one may control to some extent magnetostatic modes via external fields or geometry.

This research proposes a conceptual model for Knowledge Services Structure applicable to Science and Technology Parks (STP) and targeted to micro, small and medium enterprises, in order to improve the business - university - research centers relationship. The idea emerged from exploratory studies on STP and the observation of a knowledge gap on this subject: academic studies that have proposed support services structures to link companies - university - research centers in STP were not available. The study methodology is composed by: exploratory studies complemented by action research. Five aspects of analysis (knowledge services, business development, ordinary/ S and T infrastructure services, expansion of area, and image / visibility) were chosen; a questionnaire based on the these aspects were elaborated and applied by e-mail (e-survey), using as data-base the IASP associated members for the selection of potential respondents. The questionnaire was answered by STP managers from different countries (Spain, Italy, Portugal, Germany, United Kingdom, China, Brazil, Turkey and Uruguay) and, for a deeper and better answers understanding, presential interviews were conducted in certain European STP. After presentation, analysis and discussion of the results, a conceptual model of knowledge service structure for STP has been made, using as basis the Technology Park of Sao Paulo structure. During the formulation of the conceptual model stage, a brief discussion on the importance of knowing and meet the customer needs meant on the inclusion of a customer-interface in the final model.

Biomonitoring of atmospheric pollution (with emphasis on trace elements) - BioMAP. Proceedings of an international workshop

International Nuclear Information System (INIS)

2000-06-01

Some organisms accumulate atmospheric contaminants over certain periods of time and concentrate them, thus allowing reliable analytical measurements if the organisms are suitably chosen. Measurements of contaminants accumulated by such organisms (biomonitors) provide information on the integrated exposure over an extended period of time. They may also be present in remote areas, and no expensive technical equipment is involved in collecting them. Therefore, biomonitoring can be an effective tool for pollutant mapping and trend monitoring by real time and retrospective analysis. The IAEA is making concerted efforts to promote the practical use of nuclear and related analytical techniques in studies of non-radioactive environmental pollutants that may impact human health, and one of the main emphases is on studying air contaminants. The idea of organizing a workshop on biomonitoring atmospheric pollution arose during an IAEA Technical Co-operation Project on Monitoring of Trace Element Air Pollution, carried out at the Instituto Tecnologico e Nuclear (ITN), Portugal, with substantial technical support by the Interfaculty Reactor Institute (IRI) of the Delft University of Technology (TUDelft), Netherlands. The International Workshop on Biomonitoring of Atmospheric Pollution (With Emphasis on Trace Elements) - BioMAP, was held in Lisbon, Portugal, from 21 to 24 September 1997.

The TTPIXE technique was used for the determination of the concentrations of major, minor and trace elements in phosphate rock and phosphogypsum samples. All the samples came from a fertilizer industry site in Huelva (SW of Spain). The analyses were done using proton beams from the 3 MV Van de Graaff accelerator of the 'Instituto Tecnologico e Nuclear' (ITN), Sacavem (Portugal). The aim was to obtain data about the distribution of the different elements in the process of P 2 O 5 production in the factory. The information obtained allowed evaluation of the effectiveness of the chemical treatment employed, and gave a detailed information about the elemental composition of phosphogypsum, the main by-product of phosphate fertilizer production. These data can be useful to define the phosphogypsum management and to evaluate its environmental impact

UMA PROSPOSTA DEDUTIVISTA PARA PRINCÍPIOS CONTÁBEIS

Directory of Open Access Journals (Sweden)

Paulo Schmidt

2009-09-01

Full Text Available A proposta deste estudo a apresentar um breve relato sobre a evolução do pensamento cientifico ocorrida na física com a substituição dos princípios contábeis e filosófico, desde a Antiguidade grega ate os dias de hoje, como forma de fundamentar o posicionamento contrario ao raciocínio indutivo para o estabelecimento de uma estrutura conceitual para a contabilidade e para o desenvolvimento dos princípios contábeis. Apos essa incursão pelo campo filosófico, será aduzido um dos trabalhos de D. R. Scott, ex-professor da Universidade de Michigan, que já na década de 1930 defendia o processo de raciocínio dedutivo e a necessidade de coerência e unidade para o estabelecimento dos princípios contábeis. Este estudo justifica-se, principalmente, porque ainda existem pesquisadores da área contábil que defendem o método indutivo com único procedimento cientifico capaz de levar a certeza, Como defendia Descartes. Alem disso, mesmo apos a revolução cientifica princípios teóricos de Newton, pelos princípios da teoria da relatividade de Einstein, alguns pesquisadores defendem a imutabilidade dos princípios contábeis, como sendo verdades indubitáveis, não aceitando o permanente desenvolvimento da teoria contábil e sua continua adaptabilidade a nova realidade ambiental. A contabilidade, assim como toda disciplina do conhecimento humano que postula um patamar cientifico, deve estruturar-se com base em um conjunto de princípios racionalmente dispostos. Diante desse panorama, faz-se mister inquirir se os princípios contábeis podem ser oniscientes e impassíveis as mudanças do mundo?

Full Text Available The abstracts of nursing theses and dissertations written in Brazil from 1963 to 1979 and included in "Information on Nursing Research and Researchers" were analyzed and classified. After epistemologic discussion of the subject, the method inductive or deductive used by the author to elaborate his/her thesis was classified on the basis of the summary, and an attempt was made to determine the phase of the method attained in the investigation. It was concluded that the inductive method is the privileged one, even trough it is not used in all its phases, the same occuring with the deductive method, a fact that led the authors to suggest that this factor may be blocking the onset of new problems and the formulation of new theories.

Buildings use a large amount of energy to operate and are one of the main sources of contaminating emissions. A building is a complex system and all of their components contribute to the total energy demand. The technology to construct zero-energy buildings is already available, but obstacles exist such as the lack of information and technical training of architects and engineers to design highly energy efficient buildings. The present article describes the progress to-date and the future prospects for the design and construction of zero-energy buildings, as well as the problems involved in its implementation. [Spanish] Los edificios usan una gran cantidad de energia para operar y son una de las principales fuentes de emisiones contaminantes. Un edificio es un sistema complejo y todos sus componentes contribuyen a la demanda total de energia.

of specific technological solutions. [Italian] Questo articolo si prefigge di valutare l'impatto del cambiamento tecnologico (a valle del contatore) nell'industria energetica a rete (elettricita' e gas naturale). Le prestazioni degli impianti di generazione elettrica di piccola taglia e delle pompe di calore elettriche sono significamente migliorate negli ultimi dieci anni, rendendo possibile (o maggiormente conveniente) due traiettorie tecnologiche alternative: il sistema basato esclusivamente sull'utilizzo del gas naturale, possibile grazie all'utilizzo di piccoli impianti di cogenerazione che prefigurerebbe una forte decentrazione dell'offerta energetica; il sistema basato esclusivamente (o quasi) sull'utilizzo dell'elettricita', che invece, grazie all'utilizzo della pompa di calore reversibile, accentuerebbe le caratteristiche di centralizzazione dell'offerta. L'articolo confronta le due alternative sulla base dei corrispondenti costi sociali, somma dei costi interni (privati) e dei costi esterni (di natura prevalentemente ambientale), e conclude che, in termini paradigmatici, il sistema totalmente elettrico risulta preferibile ad una forte decentralizzazione basata sulla diffusione della cosiddetta decentrazione distribuita. Il lavoro tiene opportunamente conto della forte incertezza in merito alle stime dei costi esterni (ed in particolare del costo marginale delle emissioni di gas-serra) e suggerisce che l'attuale grande interesse nello sviluppo della generazione distribuita potrebbe essere attribuibile alla presenza di distorsioni di mercato.

For the last 35 years, the average temperature of the planet has been steadily increasing- Are the greenhouse gases emitted by human beings the cause? What will the consequences be? What can we do? The fourth report of the intergovernmental Panel on Climate change tries to answer these questions. There are clear signs of thawing that primary affect Greenland and the Antarctic, but there are still many doubts what the consequences will be throughout the century. In any case, it seems obvious that, if greenhouse gas emissions are not substantially reduced very soon, the rising temperature trend and its associated consequences will persist beyond the 21st century.

Se encuadra dentro de la tradiccion de la estadistica aplicada y la sociologia del conocimiento. Atiende especialmente a dos conjuntos de temas de interes, por una parte, las caracteristicas principales que determinan el nivel y tipo de produccion academica producida por las unidades de investigacion y por los propios investigadores; por otra, la utilizacion que se hace de los metodos y tecnicas de investigacion puesto que de ello tambien depende el modo de produccion cientifica. Los puntos novedosos de esta tesis son: la medicion cuantitativa del objeto de estudio, la suma de los productos y las condiciones externas a la produccion del conocimiento mas otros elementos internos como las caracteristicas de los investigadores y la metodologia utilizada para desarrollar sus trabajos; y, finalmente, el uso de las nuevas tecnologias. El aprovechamiento de los recursos estadisticos y las fuentes de informacion secundarias se complementan con el diseno propio de una encuesta donde se implementa las caracteristicas descritas en un capitulo anterior sobre los metodos cientificos mas idoneos descritos en los principales manuales y articulos cientificos desde distintas disciplinas de conocimiento. Dicha encuesta ha sido desarrollada como un programa propio y en base a los mas innovadores usos de la tecnologia en la metodologia de encuestas.

The Direccion General de Desarrollo Tecnologico of the Secretaria de Planeacion y Desarrollo (main directorate of technological development of the secretariat of planning and technological development) of the Secretaria de Energia (Sener), with the support of the World Bank performed a study, coordinated by Pablo Mulas del Pozo to analyze the possible penetration of the renewable energy sources in Mexico between today and year 2030. In this project are included as small renewable sources the small hydroelectric plants (mini, micro and smaller than 20 MW), the geothermal, the solar energy, the wind energy and the biomass. As part of this study three large lines of reflection are contemplated: (1) a bibliographical revision of the possible futures of the renewable energies, including some projections over the future evolution of the national power sector, and over the technological status of the same ones; (2) Projections on the possible future evolution of the national power sector and the possible penetration of the renewable sources of energy in it, using a simulation model (LEAP model); and (3) Groups of approach to consult experts on different aspects related to the possible future penetration of the renewable sources of energy in Mexico (especially, on present and future obstacles that face the renewable sources in our country, the possible carrying events of future which could modify the rate of penetration of these energies, and possible policy guidelines that could benefit the penetration of the same ones as of today).

Robots, more than any other machine, come close to human abilities of acting and interacting. Robots are created by human intelligence, they are perceived however through the collective imagery of post-humanistic culture. To reflect on the relation between robot and man means to investigate whether robots are a reflection of mankind, or if technologic ideology has slowly molded the subject: the man of the present is a robot.

Full Text Available This research aims to determine information regarding the level of job satisfaction of the Mexican Institutes of Technology (TecNM. in northeastern México with a structural equation model. The methodology designed to explain job satisfaction level consisted of a survey questioner with 37 questions applied to a sample of 485 professors and administrators from the National Institutes of Technology located in Tamaulipas Mexico (Cd. Victoria, Matamoros, Nuevo Laredo, Nuevo León (Linares City and Coahuila (Saltillo. The sample was random, stratified, and structured with questions mostly using a Likert scale. Six fundamental hypotheses were formulated for testing a structural equation model with job satisfaction as dependent variable. A database of cross section data was created with the sample, and processed with a statistical data analysis software called SmartPLS V. 2.0 (M3. The results of the structural model show that two of the five constructs are highly relevant and statistically significant on their impact on job satisfaction and they refer to the benefits received by employees and the working environment we live in institutions. It is concluded generally that the perception we have in relation to variables that influence job satisfaction are not significant as we think.

The aim of the present document is to supply general information concerning fossil fuels that represent, today and for the near future, the main energy source of our planet. New fossil fuel technologies are in continual development with two principal goals: to decrease environmental impact and increase transformation process efficiency. Examples of this effort are: (1) gas-steam combined cycles integrated with coal gasification plants, or with pressurized-fluidized-bed combustors; (2) new cycles with humid air or coal direct fired turbine, now under development. In the first part of this document the international and national energy situations and trends are shown. After some brief notes on environment problems and alternative fuels, such as biomasses and municipal wastes, technological aspects, mainly relevant to increasing fossil-fueled power plant performances, are examined in greater depth. Finally the research and technological development activities of ENEA (National Agency for New technologies, Energy and the Environment) Engineering Branch in order to improve fossil fuels energy and environmental use are presented.

Within the context of the nascent e-Science infrastructure in Venezuela, we describe several webbased scientific applications developed at the Centro Nacional de Calculo Cientifico Universidad de Los Andes (CECALCULA), Merida, and at the Instituto Venezolano de Investigaciones Cientificas (IVIC), Caracas. The different strategies that have been followed for implementing quantum chemistry and atomic physics applications are presented. We also briefly discuss a damage portal based on dynamic, nonlinear, finite elements of lumped damage mechanics and a biomedical portal developed within the framework of the E-Infrastructure shared between Europe and Latin America (EELA) initiative for searching common sequences and inferring their functions in parasitic diseases such as leishmaniasis, chagas and malaria.

Pedagogia artistica: la conceptualizacion y la creatividad en estudiantes de ciencias de sexto grado

Science.gov (United States)

Ortiz Colon, Edwin A.

Se realizo un estudio fenomenologico sobre la conceptualizacion, la creatividad y el valor del dibujo en propiciar un contexto creativo para el aprendizaje de ciencias de sexto grado. La conceptualizacion se interpreto como un proceso que ocurre en las relaciones que los estudiantes establecen entre los temas de estudio y las ideas principales, las experiencias previas, las creencias personales, el tiempo y el valor de la conservacion ambiental. La esencia de la creatividad se definio en funcion de la imaginacion, las destrezas, la intencion, la libertad de pensamiento y expresion y el contexto. El dibujo propicio un ambiente creativo de aprendizaje en las ciencias al facilitar el uso del pensamiento cientifico profundo, el inquirir artistico y la expresion libre.

Full Text Available O homem originou-se no Nordeste da África e expandiu-se por todo o planeta nestes últimos 2.500.000 anos. A descrição das características do espaço terrestre tem sido registrada desde os Gregos, porém a Geografia somente tornou-se um conhecimento cientifico no século XIX. A conquista do espaço expandiu-se para além dos limites do planeta e atingiu Marte, porém a descrição das novas áreas tem sido feitas conforme os princípios "geo''gráficos. Neste contexto questiona-se: deveria a analise geográfica manter-se presa à Geo?

Full Text Available O ecologísmo tem colocado em cheque as leis capitalistas de mercado, principalmente na sua fase globalizada, devido à apropriação e exploração inconsequente dos recursos naturais. Ao mesmo tempo tem apontado que o meio ambiente não se reduz ao tratamento somente cientifico da natureza. O presente artigo ressalta aspectos importantes do ecologísmo como a participação das mulheres, o marxismo, o neo-narodnismo, etc. e é rico em exemplos de problemas ambientais decorrentes das relações de produção. O ecologísmo dos pobres é apontado como uma perspectiva necessária às lutas ambientais no Terceiro Mundo.

As piroxenas sao um vasto grupo de silicatos minerais encontrados em muitas rochas igneas e metamorficas. Na sua forma mais simples, estes silicatos sao constituidas por cadeias de SiO3 ligando grupos tetrahedricos de SiO4. A formula quimica geral das piroxenas e M2M1T2O6, onde M2 se refere a catioes geralmente em uma coordenacao octaedrica distorcida (Mg2+, Fe2+, Mn2+, Li+, Ca2+, Na+), M1 refere-se a catioes numa coordenacao octaedrica regular (Al3+, Fe3+, Ti4+, Cr3+, V3+, Ti3+, Zr4+, Sc3+, Zn2+, Mg2+, Fe2+, Mn2+), e T a catioes em coordenacao tetrahedrica (Si4+, Al3+, Fe3+). As piroxenas com estrutura monoclinica sao designadas de clinopiroxenes. A estabilidade das clinopyroxenes num espectro de composicoes quimicas amplo, em conjugacao com a possibilidade de ajustar as suas propriedades fisicas e quimicas e a durabilidade quimica, tem gerado um interesse mundial devido a suas aplicacoes em ciencia e tecnologia de materiais. Este trabalho trata do desenvolvimento de vidros e de vitro-cerâmicos baseadas de clinopiroxenas para aplicacoes funcionais. O estudo teve objectivos cientificos e tecnologicos; nomeadamente, adquirir conhecimentos fundamentais sobre a formacao de fases cristalinas e solucoes solidas em determinados sistemas vitro-cerâmicos, e avaliar a viabilidade de aplicacao dos novos materiais em diferentes areas tecnologicas, com especial enfase sobre a selagem em celulas de combustivel de oxido solido (SOFC). Com este intuito, prepararam-se varios vidros e materiais vitro-cerâmicos ao longo das juntas Enstatite (MgSiO3) - diopsidio (CaMgSi2O6) e diopsidio (CaMgSi2O6) - Ca - Tschermak (CaAlSi2O6), os quais foram caracterizados atraves de um vasto leque de tecnicas.

Daniele Portela de Oliveira

2014-02-01

Full Text Available Estimates of genetic parameters are important to study characteristics that are to be included in a breeding program of a genetic group. The information of 594 weights from 211 lambs of a genetic group of naturalized Sul-mato-grossenses sheep belonging to Manoel de Barros Foundation and breeding at Centro Tecnologico de Ovinos from Anhanguera-Uniderp University was used. The estimation of variance components in unicaracter and bicaracter analysis were carried out through Bayesian inference. Estimates of heritability ranged from unicaracter analyses (0.22 to 0.47 and the bicaracter analyses (0.13 to 0.78. The maternal environmental permanent effect was higher in birth weight and average daily gain from birth to 50 days in 24.2% and 19.5%, respectively, in the observed variation. Estimates of heritability, maternal environmental permanent effect participation, phenotypic and genetic correlations indicate that selection for average daily gain from birth to 90 days would imply increases in weight at 50 days, weight at 90 days and average daily gain from 50 to 90 days of lambs with no significant increase in birth weight and average daily gain birth at 50 days.

Development and implementation of computational geometric model for simulation of plate type fuel fabrication process with microspheres dispersed in metallic matrix

International Nuclear Information System (INIS)

Lage, Aldo M.F.; Reis, Sergio C.; Braga, Daniel M.; Santos, Armindo; Ferraz, Wilmar B.

2005-01-01

In this report it is presented the development of a geometric model to simulate the plate type fuel fabrication process with fuels microspheres dispersed in metallic matrix, as well as its software implementation. The developed geometric model encloses the steps of pellets pressing and sintering, as well as the plate rolling passes. The model permits the simulation of structures, where the values of the various variables of the fabrication processes can be studied and modified. The following variables were analyzed: microspheres diameters, density of the powder/microspheres mixing, microspheres density, fuel volume fraction, sintering densification, and rolling passes number. In the model implementation, which was codified in DELPHI programming language, systems of structured analysis techniques were utilized. The structures simulated were visualized utilizing the AutoCAD applicative, what permitted to obtain planes sections in diverse directions. The objective of this model is to enable the analysis of the simulated structures and supply information that can help in the improvement of the dispersion microspheres fuel plates fabrication process, now in development at CDTN (Centro de Desenvolvimento da Tecnologia Nuclear) in cooperation with the CTMSP (Centro Tecnologico da Marinha em Sao Paulo).

The thesis shows the design and implementation of loss of field (40) and overcurrent (50/51) relays, minimum excitation limiter (MEL), over excitation limiter (OEL) and Voltage / Frequency limiter (V/Hz). It is also shown the development of a synchronous machine mathematical model for representing the conditions of open circuit, three phase short-circuit at stator terminals and short/open circuit at the field winding. Finally, a study about the magnetic saturation effect on the protection against loss of excitation is shown. It is studied the effects on the relay settings by using the X{sub d} saturated reactance. All the tests were applied for a salient-pole synchronous machine of 7 kVA, 220 V and 1800 rpm. The machine is at the Propulsion Laboratory of the Instituto Tecnologico de La Laguna.

A review of current technologies used to control gaseous emissions produced by combustion processes is given. Fly ash and particulates are successfully removed (99,9%) by using electromagnetic filters and fabric filters. Desulfurization is achieved by adding limestone into the furnace or using scrubbers where gases are mixed with a water solution plus mentalizing agents. Denitrification is performed by three ways: better conditions of the burner, by injecting chemical products into the furnace and using catalysts.

The viability of the association of the methods of concentration in resins - developed by the 'Fundacao Centro Tecnologico de Minas Gerais' - CETEC - with neutron activation is studied. Besides the study of the resin behaviour under neutron irradiation, studies on the variation of the retention rate in function of ph and of the duration of contact of the solution with the resin are carried on. The element to which greater emphasis in given is mercury, whose analysis presents generally serious difficulties. To support the analyses, two automatic methods for gamma spectra analysis, now in operation, were studied and established. In the experimental conditions employed, the detection limits were: 0.5 ppb for cobalt and 1 ppb for mercury. (I.C.R.) [pt

SICTI is a software tool for registering health records in critical medicine environments. Version 1.0 has been in use since 2003. The Biomedical Engineering Group (Nucleo de Ingenieria Biomedica), with support from the Technological Development Programme (Programa de Desarrollo Tecnologico), decided to develop a new version, to provide an aid for more critical medicine processes, based on a framework which would make the application domain change oriented. The team analyzed three alternatives: to develop an original product based on new research, to base the development on OpenEHR framework, or to use HL7 RIM as the reference model for SICTI. The team opted for OpenEHR. This work describes the use of OpenEHR, its strong and weak points, and states future work perspectives

In July of 1991 Argentina and Brazil assume the commitment exclusively for the pacific use of the nuclear energy and of their respective nuclear programs through a Bilateral agreement. This Agreement also believes the ABACC, for monitoring the execution of the assumed commitments. From their beginnings, the Agency was involved in the application of safeguards in plants of ultra-centrifugation being this a so much topic of relevance for ABACC like for the IAEA. To preserve technological secrets, for demand of the operator, the cascades of centrifuges find hidden behind of panels. ABACC understanding this necessity, it has explored alternatives that allow to reconcile the interests of all the involved parts. A focus of safeguards based on the control of the perimeter one has come using in the plants of small installed capacity and in the first two cascades of a commercial plant in construction. In the work the efficiency of this focus is discussed as increases the capacity of the plant and with it concludes that it will be necessary to begin a dialogue on the future implementation of methods more standardized of control in the commercial plant, giving time so that the designs are adapted to the new reality.

2004-01-01

This book is conceived as an introductory text into the theory of syntactic and semantic information, and information flow. Syntactic information theory is concerned with the information contained in the very fact that some signal has a non-random structure. Semantic information theory is concerned with the meaning or information content of messages and the like. The theory of information flow is concerned with deriving some piece of information from another. The main part will take us to situation semantics as a foundation of modern approaches in information theory. We give a brief overview o

Information adaptation the interplay between Shannon information and semantic information in cognition

CERN Document Server

Haken, Hermann

2015-01-01

This monograph demonstrates the interplay between Shannon information and semantic information in cognition. It shows that Shannon’s information acts as driving force for the formation of semantic information; and vice versa, namely, that semantic information participates in the formation of Shannonian information. The authors show that in cognition, Shannonian and semantic information are interrelated as two aspects of a cognitive process termed as information adaptation. In the latter the mind/brain adapts to the environment by the deflating and/or inflating of the information conveyed by the environment. In the process of information adaptation, quantitative variations in Shannon’s information entail different meanings while different meanings affect the quantity of information. The book illustrates the above conceptually and mathematically by reference to three cognitive processes: pattern recognition, face learning and the recognition of a moving object.

Electromagnetic model of a three phase induction motor using finite elements; Modelo electromagnetico de un motor de induccion trifasico usando elementos finitos

Energy Technology Data Exchange (ETDEWEB)

Ruvalcaba Marquez, Carlos

2003-02-15

This thesis shows a non-linear electromagnetic analysis of a three-phase induction machine using the two-dimensional finite element method (2D FEM). It is necessary to solve the diffusion equation to obtain the average magnetic vector potential of the FE machine model. The solution of this equation gives the induced eddy currents locally or globally inside the FE machine model. The induction machine is rated at 2.2 kw, 220 V, 60 Hz, and it can handle two different speeds, 1750/1150 rpm with a current consumption of 9.6/11.0 A, respectively. This machine is at the Laboratorio de Propulsion of the Instituto Tecnologico de la Laguna. The eddy currents induced in the conducting material appear because the FE model of the machine model is supplied by a sinusoidal current; finally, the depth penetration factor is considered on the FE mesh to achieve a better skin effect representation. [Spanish] En este trabajo de tesis se realiza un analisis electromagnetico no lineal de un motor de induccion trifasico empleando el metodo del elemento finito en dos dimensiones. De manera especifica, se calcula el potencial magnetico vectorial promedio del modelo de elemento finito del motor mediante la solucion de la ecuacion de difusion. Al resolver la ecuacion de difusion se obtiene la densidad de corrientes de eddy que se inducen ya sea en sentido local o global en el modelo del motor. El motor de induccion analizado esta disenado para operar a dos velocidades, 1750/1150 rpm, tiene una capacidad de 2.2 kW, 220 V, 9.6/11.0 A, 60 Hz, y se encuentra instalado en el Laboratorio de Propulsion del Instituto Tecnologico de la Laguna. Debido a que el modelo electromagnetico del motor de induccion es alimentado por una fuente de corriente senoidal, se tiene una induccion de corrientes de eddy en el material conductor. En el diseno de la malla se considero el factor de penetracion para lograr una mejor representacion del efecto piel.

Information,Informal finance,and SME financing

Informal finance exists extensively and has been playing an important role in small-and medium-sized enterprise (SME) financing in developing economies,This paper tries to rationalize the extensiveness of informal finance.SME financing suffers more serious information asymmetry to the extent that most SMEs are more opaque and can only provide less collateral.Informal lenders have an advantage over formal financial institutions in collecting "soft information" about SME borrowers.This paper establishes a model including formal and informal lenders and high-and low-risk borrowers with or without sufficient collateral and shows that the credit market in which informal finance is eliminated will allocate funds in some inefficient way,and the efficiency of allocating credit funds can be improved once informal finance is allowed to coexist with formal finance.

Informed consent: information or knowledge?

Berger, Ken

A fiduciary relationship should be nurtured between patient and physician. This requires effective communication throughout all aspects of care - especially pertaining to treatment decisions. In the context of illness as experienced by the patient a unique set of circumstances is presented. However, communication in an illness context is fraught with problems. The patient is vulnerable and the situation may be overwhelming. Voluminous amounts of information are available to patients from a host of health care providers, family members, support groups, advocacy centers, books, journals, and the internet. Often conflicting and confusion, frequently complex, this information may be of greater burden than benefit. Some information is of high validity and reliability while other information is of dubious reliability. The emotional freight of bad news may further inhibit understanding. An overload of information may pose an obstacle in decision-making. To facilitate the transformation of information into knowledge, the health care provider must act on some occasions as a filter, on other occasions as a conduit, and on still other occasions simply as a reservoir. The evolution of patient rights to receive or refuse treatment, the right to know or not to know calls for a change in processing of overwhelming information in our modem era. In this paper we will discuss the difference between information and knowledge. How can health care providers ensure they have given their patients all necessary and sufficient information to make an autonomous decision? How can they facilitate the transformation of information into knowledge? The effect of knowledge to consent allows a more focused, relevant and modern approach to choice in health care.

The use of the trnH-psbA plastid spacer and the matK coding sequence were evaluated as possible markers for the molecular characterization of two accessions quince (C. oblonga) from Argentina and Costa Rica. The research was carried out by the Centro de Investigacion en Biotecnologia del Instituto Tecnologico de Costa Rica (ITCR), during the year 2014. The amplified products were analyzed with MEGA v6.0 software to calculate the genetic distances using the Tamura-Nei model . The matK sequence presented the highest percentage of variable sites and intraspecific distance, indicating the presence of polymorphisms between the accessions. The use of the trnH-psbA spacer for quince had little capacity for discrimination because at the intra-specific level this locus presented less divergence. (author) [es

Gran parte de la investigacion acerca de la ensenanza de las ciencias se dedica a estudiar la forma o manera en que los estudiantes visualizan los conceptos cientificos. Para Driver (1983) esas ideas o concepciones se conocen como concepciones alternativas; las cuales pueden ocasionar dificultad para comprender los conceptos de las diferentes areas del conocimiento. El proposito de este estudio fue: (a) indagar como las distintas etapas del ABP permiten explorar las concepciones alternativas que poseen los estudiantes de nivel elemental acerca de los estados de agregacion de la materia y, (b) explorar en que medida el ABP permite identificar e incorporar las concepciones alternativas que poseen los estudiantes de nivel elemental con relacion al concepto de estados de agregacion de la materia para facilitar su aprendizaje. Con el fin de explorar las concepciones alternativas en el tema de los estados agregados de la materia se implanto la estrategia de Aprendizaje Basado en Problemas (ABP) con estudiantes de quinto grado de nivel elemental. Se utilizo la metodologia mixta con varias estrategias de recopilacion de datos, como una pre y pos prueba para elucidar el conocimiento previo y al mismo tiempo las concepciones alternativas sobre el tema bajo estudio y luego verificar el aprendizaje en los estudiantes. Asimismo, el uso de mapas conceptuales para determinar la profundidad del tema estudiado y el entrelazamiento de los conceptos Una tercera estrategia fue el grupo focal para tomar en cuenta la impresion de los estudiantes acerca del proyecto ABP. El aspecto colaborativo y cooperativo fue un factor fundamental, ya que el aprendizaje ocurrio en ese contexto educativo. Para los hallazgos de esta investigacion fue tan importante el conocimiento previo como los procesos que se generaban para que la adquisicion del mismo fuera de forma significativa y funcional (Escribano & Del Valle, 2010). La estrategia de ABP constituyo en este estudio una forma para indagar las

Information asymmetries, information externalities, oil companies strategies and oil exploration information efficiency

International Nuclear Information System (INIS)

Nyouki, E.

1998-07-01

Both for economics (in general) and energy economics matters, it is important to reach oil exploration efficiency. To achieve this aim, a pragmatic approach is to use the concept of information efficiency which means that the different tracts have to be drilled in the decreasing order of estimated profitabilities, estimations being made on the basis of the best (in the sense of reliability) available information. What does 'best available information' mean? It corresponds either to the information held by the most experienced oil companies (due to the existence of information asymmetries to the profit of these companies), or to information revealed by the drilling and which allows to revise probabilities of success on neighboring tracts with similar geological features (due to the existence of information externalities). In consideration of these information asymmetries and externalities, we will say that exploration is information efficient when. -- on the one hand, initial exploration choices are directed by the most experienced companies, - and, on the other hand, during the drilling phase, in the face of the information externality, companies adopt a sequential drilling, i.e. excluding both over-investment and strategic under-investment. The topic we deal with in this thesis is then to know if oil companies, when they are put in normal competition conditions, are likely to make emerge a state of information efficiency in exploration, the analysis being conducted theoretically and empirically.

The purpose of this work was to verify the 25 Gy dose using the ISO standard ISO/TR 13409 for the production of bone grafts from the Tissue Bank ORTOP of the Complejo Cientifico Ortopedico Internacional Frank Pais. We performed two principal microbiological activities: bioburden estimate, pre-sterilization count plus a compensation for the efficiency of the recovery method, by ISO 11737-1 and test of sterility by ISO 11737-2. The techniques for Bioburden estimation could be direct or indirect. Choice of direct vs. indirect depends on number of contaminating micro-organisms, product configuration, ability to remove microbial contamination, effect of removal method on microbial viability, types and location of micro-organisms, nature of product and culture conditions. For a test of sterility, he product unit or SIP putted direct immersion in educated culture medium and incubate. Keep precaution to minimize level to the false positives is necessary

Information in organisations: directions for information management

Directory of Open Access Journals (Sweden)

Joyce Kirk

1999-01-01

Full Text Available The work of managers in small and medium-sized enterprises is very information-intensive and the environment in which it is done is very information rich. But are managers able to exploit the wealth of information which surrounds them? And how can information be managed in organisations so that its potential for improving business performance and enhancing the competitiveness of these enterprises can be realised? Answers to these questions lie in clarifying the context of the practice of information management by exploring aspects of organisations and managerial work and in exploring the nature of information at the level of the organisation and the individual manager. From these answers it is possible to suggest some guidelines for managing the integration of business strategy and information, the adoption of a broadly-based definition of information and the development of information capabilities.

Informal information for web-based engineering catalogues

Science.gov (United States)

Allen, Richard D.; Culley, Stephen J.; Hicks, Ben J.

2001-10-01

Success is highly dependent on the ability of a company to efficiently produce optimal designs. In order to achieve this companies must minimize time to market and possess the ability to make fully informed decisions at the early phase of the design process. Such decisions may include the choice of component and suppliers, as well as cost and maintenance considerations. Computer modeling and electronic catalogues are becoming the preferred medium for the selection and design of mechanical components. In utilizing these techniques, the designer demands the capability to identify, evaluate and select mechanical components both quantitatively and qualitatively. Quantitative decisions generally encompass performance data included in the formal catalogue representation. It is in the area of qualitative decisions that the use of what the authors call 'Informal Information' is of crucial importance. Thus, 'Informal Information' must often be incorporated into the selection process and selection systems. This would enable more informed decisions to be made quicker, without the need for information retrieval via discussion with colleagues in the design environment. This paper provides an overview of the use of electronic information in the design of mechanical systems, including a discussion of limitations of current technology. The importance of Informal Information is discussed and the requirements for association with web based electronic catalogues are developed. This system is based on a flexible XML schema and enables the storage, classification and recall of Informal Information packets. Furthermore, a strategy for the inclusion of Informal Information is proposed, and an example case is used to illustrate the benefits.

deficiency on cerebrovascular development cannot be separated. However, as PGF was strongly expressed in the developing brain at all timepoints, we suggest that local PGF has a more important role than distant maternal or placental sources. Full PGF loss is not expected in PE pregnancies, predicting that the effects of PGF deficiency identified in this model will be more severe than any effects in PE-offspring. These studies provoke the question of whether PGF expression is decreased and cerebral vascular maldevelopment occurs in fetuses who experience a preeclamptic gestation. These individuals have already been reported to have elevated risk for stroke and cognitive impairments. N/A.

Bapat, Shweta S; Patel, Harshali K; Sansgiry, Sujit S

2017-10-16

In this study, we evaluate the role of information anxiety and information load on the intention to read information from prescription drug information leaflets (PILs). These PILs were developed based on the principals of information load and consumer information processing. This was an experimental prospective repeated measures study conducted in the United States where 360 (62% response rate) university students (>18 years old) participated. Participants were presented with a scenario followed by exposure to the three drug product information sources used to operationalize information load. The three sources were: (i) current practice; (ii) pre-existing one-page text only; and (iii) interventional one-page prototype PILs designed for the study. Information anxiety was measured as anxiety experienced by the individual when encountering information. The outcome variable of intention to read PILs was defined as the likelihood that the patient will read the information provided in the leaflets. A survey questionnaire was used to capture the data and the objectives were analyzed by performing a repeated measures MANOVA using SAS version 9.3. When compared to current practice and one-page text only leaflets, one-page PILs had significantly lower scores on information anxiety ( p information load ( p Information anxiety and information load significantly impacted intention to read ( p < 0.001). Newly developed PILs increased patient's intention to read and can help in improving the counseling services provided by pharmacists.

One of the features of contemporaneityis the global spread of ICT, combined with poor governance and other difficulties in the construction of innovation infrastructures that are based on them in some countries. This leads to the reproduction of threats, primarily related to the ability to use ICT for purposes that are inconsistent with the objectives of maintaining international peace and security, compliance with the principles of non-use of force, non-interference in the internal affairs of states, etc. In this regard, include such terms as "a threat of information warfare", "information terrorism" and so forth. Information warfare, which stay in the policy declared the struggle for existence, and relationships are defined in terms of "friend-enemy", "ours-foreign". Superiority over the opponent or "capture of its territory" is the aim of political activity. And information security, serving activities similar process of political control, including a set of components, is a technology until their humanitarian. From the context and the decision itself is the ratio of the achieved results of information and political influence to the target - a positive image of Russia. Bringing its policy in line with the demands of a healthy public opinion provides conductivity of theauthorities initiatives in the country and increases the legitimacy of the Russian Federation actions in the world.

Design and safety analyses are presented for conversion of the Portuguese Research Reactor (RPI) from the use of HEU fuel to the use of LEU fuel. The analyses were performed jointly by the RERTR Program at the Argonne National Laboratory (ANL) and the Instituto Tecnologico e Nuclear (ITN). The LEU fuel assembly design uses U 3 Si 2 -Al dispersion fuel with 4.8 g U/cm 3 and is very similar to the HEU fuel design. The results of neutronic studies, steady-state thermal-hydraulic analyses, accident analyses, and revisions to the Operating Limits and Conditions demonstrate that the RPI reactor can be operated safely with the new LEU fuel assemblies. Delivery of the LEU fuel is expected around the end of 2006, with conversion in early 2007. The HEU fuel is planned to be returned to the US in 2008.

The concept of work meant as a set of coordinated activities according to the latest organization theories optimizes the enterprise`s information and knowledge sharing, the only durable resources of a modern organization. The information technologies and methodologies that qualify the cooperative and the group work are called Computer Supported Cooperative Work o Groupware. They allow and support collaboration, coordination and communication between members of work groups in a asynchronous way and regardless of the work place. This paper shows the innovative character and the involvement of the cooperative work. A scenario for the use and the introduction of such technologies in complex organizations is defined and a methodology for planning and development of groupware systems is presented, with the consequent estimate of the technological-organizational impact and return of investments. The case study concerns the utilization of such methodology for the development of a pilot system within Management Information System Department of ENEA. The project has two main objectives: a) planning and realization of an enterprise`s basic modular infrastructure for communication management and work group support, b) the development of a support system for the processing of the deliberation proposal concerning acts connected to the activities of the Agency (Deliberation System).

Inform: Efficient Information-Theoretic Analysis of Collective Behaviors

Directory of Open Access Journals (Sweden)

Douglas G. Moore

2018-06-01

Full Text Available The study of collective behavior has traditionally relied on a variety of different methodological tools ranging from more theoretical methods such as population or game-theoretic models to empirical ones like Monte Carlo or multi-agent simulations. An approach that is increasingly being explored is the use of information theory as a methodological framework to study the flow of information and the statistical properties of collectives of interacting agents. While a few general purpose toolkits exist, most of the existing software for information theoretic analysis of collective systems is limited in scope. We introduce Inform, an open-source framework for efficient information theoretic analysis that exploits the computational power of a C library while simplifying its use through a variety of wrappers for common higher-level scripting languages. We focus on two such wrappers here: PyInform (Python and rinform (R. Inform and its wrappers are cross-platform and general-purpose. They include classical information-theoretic measures, measures of information dynamics and information-based methods to study the statistical behavior of collective systems, and expose a lower-level API that allow users to construct measures of their own. We describe the architecture of the Inform framework, study its computational efficiency and use it to analyze three different case studies of collective behavior: biochemical information storage in regenerating planaria, nest-site selection in the ant Temnothorax rugatulus, and collective decision making in multi-agent simulations.

Information barriers for the protection of sensitive information

International Nuclear Information System (INIS)

Dougan, A.D.; Dunn, J.; Seager, K.; Smith, M.; Beach, D.; Clinton, J.; Vanier, P.

2013-01-01

An Information Barrier is a combination of technology and procedures that prevent the release of a host country's sensitive information to a monitoring party during an inspection of a sensitive item, while enabling assurance of an accurate assessment of host country declarations regarding the item. Information barriers, as a concept, arose from the need to balance two competing requirements - specifically, certification of information protection by a host country and authentication of measurement and information accuracy by a monitoring party. The U.S. Department of Energy's National Nuclear Security Administration, in conjunction with several U.S. National Laboratories, has explored information barrier development in detail, and has continued the evolution of essential work done by the U.S. Information Barrier Working Group beginning in the late 1990's, and other international efforts, including the U.S.-Russia-IAEA Trilateral Initiative. This paper explains the rationale for information barriers, and explores the development and application of information barrier concepts for potential future arms control initiatives, including recent work and advances in capabilities. It also considers applications of information barrier concepts applied in other fields.The paper is followed by the slides of the presentation. (authors)

The 2002 Pan-American Advanced Studies Institute School on Quantum Gravity was held at the Centro de Estudios Cientificos (CECS),Valdivia, Chile, January 4-14, 2002. The school featured lectures by ten speakers, and was attended by nearly 70 students from over 14 countries. A primary goal was to foster interaction and communication between participants from different cultures, both in the layman’s sense of the term and in terms of approaches to quantum gravity. We hope that the links formed by students and the school will persist throughout their professional lives, continuing to promote interaction and the essential exchange of ideas that drives research forward. This volume contains improved and updated versions of the lectures given at the School. It has been prepared both as a reminder for the participants, and so that these pedagogical introductions can be made available to others who were unable to attend. We expect them to serve students of all ages well.

The information activity of rail passenger information staff: a foundation for information system requirements

Directory of Open Access Journals (Sweden)

Martin Rose

2006-01-01

Full Text Available Introduction. This paper examines the goal-directed information activity of passenger information staff, working in the dynamic environment of rail network control. The explicit aim is to define a meaningful set of information system requirements. The report shows how dynamic situations may lead us to question a number of established theories of information science. Method. Passenger information officers (PIOs were observed on duty within the rail command and control headquarters. Observation sessions totally eight hours involved the manual recording of sequential information flows and the associated activity of PIOs. A semi-structured management interview was also conducted to provide further insight into the organizational context. Analysis. A viewpoint-oriented analysis technique was used to analyse sequential data captured during observation sessions. Event sequences that represent and explain the viewpoints were identified and elaborated into detailed scenario descriptions. Results. The analysis both supports and contests a number of established theories from information science. Additionally, a range of 'mandatory' and 'desirable' system requirements are derived from the scenario and viewpoint analyses. Conclusion. Dynamic situations have a significant impact on information behaviour which is not always predicted by current theories of information science.

Biological information systems: Evolution as cognition-based information management.

Science.gov (United States)

Miller, William B

2018-05-01

An alternative biological synthesis is presented that conceptualizes evolutionary biology as an epiphenomenon of integrated self-referential information management. Since all biological information has inherent ambiguity, the systematic assessment of information is required by living organisms to maintain self-identity and homeostatic equipoise in confrontation with environmental challenges. Through their self-referential attachment to information space, cells are the cornerstone of biological action. That individualized assessment of information space permits self-referential, self-organizing niche construction. That deployment of information and its subsequent selection enacted the dominant stable unicellular informational architectures whose biological expressions are the prokaryotic, archaeal, and eukaryotic unicellular forms. Multicellularity represents the collective appraisal of equivocal environmental information through a shared information space. This concerted action can be viewed as systematized information management to improve information quality for the maintenance of preferred homeostatic boundaries among the varied participants. When reiterated in successive scales, this same collaborative exchange of information yields macroscopic organisms as obligatory multicellular holobionts. Cognition-Based Evolution (CBE) upholds that assessment of information precedes biological action, and the deployment of information through integrative self-referential niche construction and natural cellular engineering antecedes selection. Therefore, evolutionary biology can be framed as a complex reciprocating interactome that consists of the assessment, communication, deployment and management of information by self-referential organisms at multiple scales in continuous confrontation with environmental stresses.

Full Text Available This study analyzed college students’ reactions toward the issues of personal information. Students’ needs and seeking behaviors for personal information were assessed. Relevant literature was reviewed for framing the research questions and designing the questionnaire items for survey. Survey subjects were students from an university at northern Taiwan. A set of questionnaire items were used to collect research data. Statistical analysis from 252 valid data reveals some items were highly rated: Students reflected highly for their need of knowledge under the security threat of personal information (M = 4.29. They reacted strongly on acquiring knowledge and resources through the Internet (M = 4.24. They preferred the use of resources clear and easy to be understood (M = 4.04. However, most students had low level faith toward either government or non-governmental organizations in securing their personal information (M < 3.0 for most items. More effort among education and government should be emphasized in the future to improve personal use and reduce uncertainty in the use of personal information.

Full Text Available Introduction. The article is devoted to the problem of interaction between schoolchildren and possible informational risks transmitted on the Internet. Considering the lack of external filters on the way of harmful information streams, it is actually necessary to develop information culture of schoolchildren, their abilities to sensibly and critically interpret the information on the Internet, and choice of adequate behaviour models surfing the Web. The aim of the present research is to analyze the state of informational safety of schoolchildren while using the Internet; gaining an understanding of the role of external restrictions and opportunities of intrapersonal filtration of the harmful Internet content depending on children age. Methodology and research methods. The methodology of the research is based on modern methods aimed to consider the problem of personal socialization in modern information society. Thus, the Internet Initiatives Development Fund (IIDF questionnaire let the authors define the level of awareness of recipients on the problem under consideration. Results and scientific novelty. The theoretical analysis helped the authors predict the correlation of basic methods in order to guarantee personal safety of schoolchildren taking into account the process of maturity as well as the decrease of external filters that may stop harmful content. Empirical part of the research has enabled to reveal decrease in external control of staying of a child in network in the process of growing up against the background of restrictive attitudes prevalence among teachers and parents. Therefore, the research supposed to improve information culture of schoolchildren from the earliest ages encouraging them to sensibly and correctly interpret the information on the Internet. Practical significance. The practical recommendations to parents and teachers in order to improve informational personal safety of schoolchildren are proposed. The relevancy

Social information

Directory of Open Access Journals (Sweden)

Luiz Fernando de Barros Campos

Full Text Available Based on Erving Goffman's work, the article aims to discuss a definition of information centered on the type conveyed by individuals in a multimodal way, encompassing language and body in situations of co-presence, where face-to-face interaction occurs, and influencing inter-subjective formation of the self. Six types of information are highlighted: material information, expressive information, ritualized information, meta-information, strategic information, and information displays. It is argued that the construction of this empirical object tends to dissolve the tension among material, cognitive and pragmatic aspects, constituting an example of the necessary integration among them. Some vulnerable characteristics of the theory are critically mentioned and it is suggested that the concept of information displays could provide a platform to approach the question of the interaction order in its relations with the institutional and social orders, and consequently, to reassess the scope of the notion of social information analyzed.

Communicating stereotype-relevant information: is factual information subject to the same communication biases as fictional information?

Science.gov (United States)

Goodman, Ruth L; Webb, Thomas L; Stewart, Andrew J

2009-07-01

Factual information is more frequently read and discussed than fictional information. However, research on the role of communication in shaping stereotypes has focused almost exclusively on fictional narratives. In Experiments 1 and 2 a newspaper article containing information about heroin users was communicated along chains of 4 people. No stereotype-consistency bias was observed. Instead, a greater proportion of stereotype-inconsistent information was communicated than was stereotype-consistent or -neutral information. Three further experiments investigated explanations for the difference between the communication of fictional and factual information. Experiment 3 ruled out the possibility that participants' beliefs about the validity of the information could influence the way that it is communicated. Experiments 4 and 5 divided information into concrete (a specific event or fact) or abstract (opinion). A stereotype-consistency bias emerged only for abstract information. In summary, linguistic abstraction moderates whether stereotype-consistency biases emerge in the communication of stereotype-relevant factual information.

2008-01-01

It has been more than 25 years since Brazilian Navy started applying resources and staff in a nuclear power program in which the main objective is the necessary technology for project and construction of a nuclear power reactor and nuclear fuel production for naval propulsion. A long period project tends to be susceptible to loss of essential parcels of knowledge. The objective of the present research is to identify actions and initiatives that may improve learning and dissemination of knowledge in an organization that develops complexes projects during a long period of time. The revision of the literature about Knowledge Management allowed the researcher to select a reference that indicates how people involved in a project gets the necessary information and knowledge for developing their activities and uses them to add value and to learn how to contribute for the organization, in order to prevent nature difficulties. The adopted methodology was a case study on the implantation of the U nidade de Hexafluoreto de Uranio , which is being developed by the Centro Tecnologico da Marinha in Sao Paulo. With the application of structured and opened interviews, it was possible to identify some factors related with the attainment and dissemination of knowledge that can be developed. The result of this work was a proposal of action and initiatives that will improve the attainment of the knowledge, its structure and maintenance by the organization and the contribution by the people, of the knowledge acquired.

User acceptance of information technology has been a significant area of research for more than two decades in the field of information technology. This study assessed the acceptance of information technology in the context of Health Information Management (HIM) by utilizing Technology Acceptance Model (TAM) which was modified and applied to assess user acceptance of health information technology as well as viability of TAM as a research construct in the context of HIM. This was a descriptive- analytical study in which a sample of 187 personnel from a population of 363 personnel, working in medical records departments of hospitals affiliated to Tehran University of Medical Sciences, was selected. Users' perception of applying information technology was studied by a researcher-developed questionnaire. Collected data were analyzed by SPSS software (version16) using descriptive statistics and regression analysis. The results suggest that TAM is a useful construct to assess user acceptance of information technology in the context of HIM. The findings also evidenced the perceived ease of use (PEOU) and perceived usefulness (PE) were positively associated with favorable users' attitudes towards HIM. PU was relatively more associated (r= 0.22, p = 0.05) than PEOU (r = 0.014, p = 0.05) with favorable user attitudes towards HIM. Users' perception of usefulness and ease of use are important determinants providing the incentive for users to accept information technologies when the application of a successful HIM system is attempted. The findings of the present study suggest that user acceptance is a key element and should subsequently be the major concern of health organizations and health policy makers.

2015-10-01

Full Text Available Contemporary and future cities are often labeled as "smart cities," "ubiquitous cities," "knowledge cities" and "creative cities." Informational urbanism includes all aspects of information and knowledge with regard to urban regions. "Informational city" is an umbrella term uniting the divergent trends of information-related city research. Informational urbanism is an interdisciplinary endeavor incorporating on the one side computer science and information science and on the other side urbanism, architecture, (city economics, and (city sociology. In our research project on informational cities, we visited more than 40 metropolises and smaller towns all over the world. In this paper, we sketch the theoretical background on a journey from Max Weber to the Internet of Things, introduce our research methods, and describe main results on characteristics of informational cities as prototypical cities of the emerging knowledge society.

This paper analyzes both the carbon fiber-based development for uranium centrifuges and the research project that supports its development effort over time. The carbon fibre-based engineering properties make it a valuable supply for high technological products, such as uranium ultracentrifuge. There is no production of such fibers in Brazil. Its trade is subject to international market restrictions due to carbon fibers' dual applications. The Centro Tecnologico da Marinha em Sao Paulo (CTMSP), the Universidade de Campinas (UNICAMP), the Universidade de Sao Paulo (USP), the RADICIFIBRAS Company, and the Financiadora de Estudos e Projetos (FINEP), which is responsible for the project financial support, established a partnership aiming the development of a domestic polyacrylonitrile (Pan)-based carbon fiber industry. Such alliances or technological partnerships are best known in developed countries, such as USA and Japan, as Cooperative Research or Research Joint Ventures (RJV). (author)

Language as information system: transfer and saving of the information

Directory of Open Access Journals (Sweden)

Irina Mikhaylovna Nekipelova

2015-11-01

Full Text Available The paper is devoted to research of the language system as an information system. The language is not the information itself. It contains information minimum and has information restrictions. Under the information should be understood texts and speech, created by using a language. Modern forms of existence of living natural language are distributed databases with multiple accesses, because bearers of language constantly and concurrently use it. Language and speech always exchange information, creating a unified information environment, where a human is. At any stage of information exchange the change of self-descriptiveness takes place one way or the other. When a human try to reflect world around him, some part of reflected information is lost due to conversion into language and saving into it in formalized form. These processes of storing information are related to the fact that in the production and perception of the statements optimization mechanisms of human thinking are made. When we perceive information its preservation can happen without information loss and with the loss of information.

Technology Learning Ratios in Global Energy Models; Ratios de Aprendizaje Tecnologico en Modelos Energeticos Globales

Energy Technology Data Exchange (ETDEWEB)

Varela, M.

2001-07-01

The process of introduction of a new technology supposes that while its production and utilisation increases, also its operation improves and its investment costs and production decreases. The accumulation of experience and learning of a new technology increase in parallel with the increase of its market share. This process is represented by the technological learning curves and the energy sector is not detached from this process of substitution of old technologies by new ones. The present paper carries out a brief revision of the main energy models that include the technology dynamics (learning). The energy scenarios, developed by global energy models, assume that the characteristics of the technologies are variables with time. But this tend is incorporated in a exogenous way in these energy models, that is to say, it is only a time function. This practice is applied to the cost indicators of the technology such as the specific investment costs or to the efficiency of the energy technologies. In the last years, the new concept of endogenous technological learning has been integrated within these global energy models. This paper examines the concept of technological learning in global energy models. It also analyses the technological dynamics of the energy systems including the endogenous modelling of the process of technological progress. Finally, it makes a comparison of several of the most used global energy models (MARKAL, MESSAGE and ERIS) and, more concretely, about the use these models make of the concept of technological learning.

Alzougool, Basil; Chang, Shanton; Gray, Kathleen

2017-09-01

There has been little research that provides a comprehensive account of the nature and aspects of information needs of informal carers. The authors have previously developed and validated a framework that accounts for major underlying states of information need. This paper aims to apply this framework to explore whether there are common demographic and socioeconomic characteristics that affect the information needs states of carers. A questionnaire about the information needs states was completed by 198 carers above 18 years old. We use statistical methods to look for similarities and differences in respondents' information needs states, in terms of the demographic and socioeconomic variables. At least one information needs state varies among carers, in terms of seven demographic and socioeconomic variables: the age of the patient(s) that they are caring for; the condition(s) of the patient(s) that they are caring for; the number of patients that they are caring for; their length of time as a carer; their gender; the country that they live in; and the population of the area that they live in. The findings demonstrate the utility of the information needs state framework. We outline some practical implications of the framework.

An Evaluation of Information Consistency in Grid Information Systems

CERN Document Server

Field, Laurence

2017-01-01

A Grid information system resolves queries that may need to consider all information sources (Grid services), which are widely distributed geographically, in order to enable efficient Grid functions that may utilise multiple cooperating services. Fundamentally this can be achieved by either moving the query to the data (query shipping) or moving the data to the query (data shipping). Existing Grid information system implementations have adopted one of the two approaches. This paper explores the two approaches in further detail by evaluating them to the best possible extent with respect to Grid information system benchmarking metrics. A Grid information system that follows the data shipping approach based on the replication of information that aims to improve the currency for highly-mutable information is presented. An implementation of this, based on an Enterprise Messaging System, is evaluated using the benchmarking method and the consequence of the results for the design of Grid information systems is discu...

Information behaviour of migrant Hispanic farm workers and their families in the Pacific Northwest Information grounds, Information behaviour, Behavior, Washington, Immigrants, Information habits

Directory of Open Access Journals (Sweden)

Karen E. Fisher

2004-01-01

Full Text Available Immigrants are generally perceived to be information poor, meaning they face major challenges with finding and using greatly needed everyday information. However, little research exists from an information behaviour perspective as differences in language, culture, and other factors such as access make immigrants a difficult population to study. We explored the everyday information behaviour and information grounds of migrant Hispanic farm workers through field observation and interviews with users, non-users, and staff of community technology centres in a major agricultural area. Findings suggest that personal networks having various levels of credibility were used more readily than any other type of information source. Credibility and use of various sources seemed to relate to personal status as well as interest in information.

Collecting Information for Rating Global Assessment of Functioning (GAF): Sources of Information and Methods for Information Collection.

Science.gov (United States)

I H, Monrad Aas

2014-11-01

Global Assessment of Functioning (GAF) is an assessment instrument that is known worldwide. It is widely used for rating the severity of illness. Results from evaluations in psychiatry should characterize the patients. Rating of GAF is based on collected information. The aim of the study is to identify the factors involved in collecting information that is relevant for rating GAF, and gaps in knowledge where it is likely that further development would play a role for improved scoring. A literature search was conducted with a combination of thorough hand search and search in the bibliographic databases PubMed, PsycINFO, Google Scholar, and Campbell Collaboration Library of Systematic Reviews. Collection of information for rating GAF depends on two fundamental factors: the sources of information and the methods for information collection. Sources of information are patients, informants, health personnel, medical records, letters of referral and police records about violence and substance abuse. Methods for information collection include the many different types of interview - unstructured, semi-structured, structured, interviews for Axis I and II disorders, semistructured interviews for rating GAF, and interviews of informants - as well as instruments for rating symptoms and functioning, and observation. The different sources of information, and methods for collection, frequently result in inconsistencies in the information collected. The variation in collected information, and lack of a generally accepted algorithm for combining collected information, is likely to be important for rated GAF values, but there is a fundamental lack of knowledge about the degree of importance. Research to improve GAF has not reached a high level. Rated GAF values are likely to be influenced by both the sources of information used and the methods employed for information collection, but the lack of research-based information about these influences is fundamental. Further development of

Olken, Benjamin A; Singhal, Monica

2011-10-01

Informal payments are a frequently overlooked source of local public finance in developing countries. We use microdata from ten countries to establish stylized facts on the magnitude, form, and distributional implications of this "informal taxation." Informal taxation is widespread, particularly in rural areas, with substantial in-kind labor payments. The wealthy pay more, but pay less in percentage terms, and informal taxes are more regressive than formal taxes. Failing to include informal taxation underestimates household tax burdens and revenue decentralization in developing countries. We discuss various explanations for and implications of these observed stylized facts.

Creativity, information, and consciousness: The information dynamics of thinking.

Science.gov (United States)

Wiggins, Geraint A

2018-05-07

This paper presents a theory of the basic operation of mind, Information Dynamics of Thinking, which is intended for computational implementation and thence empirical testing. It is based on the information theory of Shannon, and treats the mind/brain as an information processing organ that aims to be information-efficient, in that it predicts its world, so as to use information efficiently, and regularly re-represents it, so as to store information efficiently. The theory is presented in context of a background review of various research areas that impinge upon its development. Consequences of the theory and testable hypotheses arising from it are discussed. Copyright © 2018. Published by Elsevier B.V.

Full Text Available In the information society, the production, distribution and use of information are freely and widely available for all issues of life. Proper and appropriate use of reliable information is especially important in health care. The present study introduces the concepts and benefits of health literacy and information literacy and its role in improving health literacy. This study was a review based on the concepts of information society, information literacy and information education to present importance of promoting information literacy on health literacy in the information society. The information society is presented by providing a platform of information technology and computer systems to attempt to exchange and develop information among people in the community. Currently, electronic and web-based health information in the mass form is available. Information as a fundamental base of the information society is a phenomenon that our decisions are affected in relation to various issues such as safety and health issues. It is important to avoid the mass of invalid, incorrect and inappropriate information which is available on the internet. This requires information literacy skills such as identifying, accessing and evaluating information. In general, it can be said that the promotion of health literacy in communities requires learning different skills in the form of information literacy.Data obtained from this study can be used in developing the long term health programs to prevention of non-communicable diseases in our country

Radiation information and informed consent for clinical trials

Energy Technology Data Exchange (ETDEWEB)

Caon, Martin [School of Nursing and Midwifery, Flinders University, Adelaide (Australia)], E-mail: martin.caon@flinders.edu.au

2008-09-01

Examples of the statements about the radiation from medical imaging in the information for participants provided to the Human Research Ethics Committee (HREC) for approval are presented and discussed. There is considerable scope for improvement in the information about radiation that is presented to potential participants in clinical trials. Many radiation statements seem only intended to allay fear and anxiety about radiation rather than providing accurate information. This situation cannot be said to be conducive to allowing the participant to give informed consent to their involvement in a clinical trial in which ionising radiation is used. As many clinical trials are international and conducted at many sites (sometimes over 100), we would expect the same statements to have been seen by members of HRECs in many countries. Few HRECs include a member who is an expert in radiation. Hence, to ensure that the information is sound, those sections of the participant information that refer to radiation should be written or reviewed by a specialist in radiation protection such as a medical physicist, a health physicist or a radiation safety officer.

Information Diffusion in Facebook-Like Social Networks Under Information Overload

Science.gov (United States)

Li, Pei; Xing, Kai; Wang, Dapeng; Zhang, Xin; Wang, Hui

2013-07-01

Research on social networks has received remarkable attention, since many people use social networks to broadcast information and stay connected with their friends. However, due to the information overload in social networks, it becomes increasingly difficult for users to find useful information. This paper takes Facebook-like social networks into account, and models the process of information diffusion under information overload. The term view scope is introduced to model the user information-processing capability under information overload, and the average number of times a message appears in view scopes after it is generated is proposed to characterize the information diffusion efficiency. Through theoretical analysis, we find that factors such as network structure and view scope number have no impact on the information diffusion efficiency, which is a surprising result. To verify the results, we conduct simulations and provide the simulation results, which are consistent with the theoretical analysis results perfectly.

INFORMATION ASSURANCE - INTELLIGENCE - INFORMATION SUPERIORITY RELATIONSHIP WITHIN NATO OPERATIONS

Directory of Open Access Journals (Sweden)

Gheorghe BOARU, Ioan-Mihai ILIEŞ

2011-01-01

Full Text Available There is a tight relationship between information assurance, the intelligence cycle and information superiority within NATO operations. The intelligence cycle has a discrete architecture and provides on-time and relevant intelligence products to the joint force commanders and to other authorized users in a specifi c joint area of operations. The intelligence cycle must follow the evolution of the operation. A permanent intelligence estimate will be performed during the military decision making process and operations execution. Information superiority is one of the most powerful intelligence cycle achievements. and decisively infuences the success of NATO joint operations. Information superiority must be preserved and enhanced through information assurance. Information assurance is an information operation that must be planned by the military in charge of operation security or by non-military experts, executed by all personnel during the entire intelligence cycle life time and employed during the planning and execution of NATO joint operations.

FINANCIAL INFORMATION, EFFECTS OF FINANCIAL INFORMATION ON ECONOMIC DECISION

TAK ISA

2010-12-01

Full Text Available Financial information has, indisputably, an important effect in economics. To form an effective capital market, financial information must be reliable and accurate. Misleading financial information always has a negative impact on economic decision taken by users. It is known that financial information as the cornerstone of financial markets, can improve economic performance in several ways. Nowadays we are facing economic crisis due to irregularities of presentation of financial statements to users. Misunderstandings cause economic recession. Detection of fraudulent financial information, is an important issue facing the auditing profession. Currently, bankruptcy of companies around the world, leaves millions of people without jobs, this is caused by financial information which is manipulated by companies. The purpose of this paper is to analyze the effects of errors and manipulation committed in the financial information sector on the real economy. Also one of the purposes of this paper is to analyze error and fraud in financial statements how it effects the real economy and the reasons for committing fraud in financial statements. Also, several suggestions are included in this study about actions that can be taken to prevent errors and manipulation in financial information.

Relationship between stakeholders' information value perception and information security behaviour

Science.gov (United States)

Tajuddin, Sharul; Olphert, Wendy; Doherty, Neil

2015-02-01

The study, reported in this paper, aims to explore the relationship between the stakeholders' perceptions about the value of information and their resultant information security behaviours. Moreover, this study seeks to explore the role of national and organisational culture in facilitating information value assignment. Information Security is a concept that formed from the recognition that information is valuable and that there is a need to protect it. The ISO 27002 defines information as an asset, which, like other important business assets, is essential to an organisation's business and consequently needs to be appropriately protected. By definition, an asset has a value to the organisation hence it requires protection. Information protection is typically accomplished through the implementation of countermeasures against the threats and vulnerabilities of information security, for example, implementation of technological processes and mechanisms such as firewall and authorization and authentication systems, set-up of deterrence procedures such as password control and enforcement of organisational policy on information handling procedures. However, evidence routinely shows that despite such measures, information security breaches and incidents are on the rise. These breaches lead to loss of information, personal records, or other data, with consequent implications for the value of the information asset. A number of studies have suggested that such problems are not related primarily to technology problems or procedural deficiencies, but rather to stakeholders' poor compliance with the security measures that are in place. Research indicates that compliance behaviour is affected by many variables including perceived costs and benefits, national and organisational culture and norms. However, there has been little research to understand the concept of information value from the perspective of those who interact with the data, and the consequences for information

HEALTH INFORMATION TECHNOLOGY IN EXCHANGE OF HEALTH INFORMATION

Directory of Open Access Journals (Sweden)

Jordan Deliversky

2016-06-01

Full Text Available Health information technology involves the exchange of health information in an electronic environment. Data protection is comprised of many elements, including where the data resides, how it is used, and who has access to it. Individually identifiable health information should be protected with reasonable administrative, technical, and physical safeguards to ensure its confidentiality, integrity, and availability and to prevent unauthorized access, use, or disclosure. Health records are among the most sensitive records available containing information concerning an individual. The unauthorized disclosure of a medical condition or diagnosis could negatively impact an individual’s personal and professional life.

Smart use of data, information and communication: the INFORM-ed Best Local Practice Project--Grafton Base Hospital.

Science.gov (United States)

Lloyd, Sheree; Collie, Jean; McInnes, Alastair; King, Kevin; Lollback, Alison; Garland, Angie

This paper describes current progress for an information management project in a medium-sized rural hospital after the first four months of the one-year project. In particular, the article examines some of the project outcomes to date as these relate to the National Hospitals and Health Reform recommendations for the smart use of data, information and communication. The paper identifies a number of important challenges and issues that have been addressed by the project and proposes that the project findings may be used to inform similar projects in other settings. These findings relate to clinician requirements for reports, investment in human resources, development, and time for information management activities. An understanding of data collected, information systems, and presentation of clinician data are also important. The benefits of information sharing in assisting quality improvement activities are particularly relevant but, more importantly, they can engage and involve clinicians in the use of information. The importance of local data, information, and knowledge is described. Finally, issues for the health information management profession, such as working collegially and sharing knowledge and expertise, are outlined.

Information logistics: A production-line approach to information services

Science.gov (United States)

Adams, Dennis; Lee, Chee-Seng

1991-01-01

Logistics can be defined as the process of strategically managing the acquisition, movement, and storage of materials, parts, and finished inventory (and the related information flow) through the organization and its marketing channels in a cost effective manner. It is concerned with delivering the right product to the right customer in the right place at the right time. The logistics function is composed of inventory management, facilities management, communications unitization, transportation, materials management, and production scheduling. The relationship between logistics and information systems is clear. Systems such as Electronic Data Interchange (EDI), Point of Sale (POS) systems, and Just in Time (JIT) inventory management systems are important elements in the management of product development and delivery. With improved access to market demand figures, logisticians can decrease inventory sizes and better service customer demand. However, without accurate, timely information, little, if any, of this would be feasible in today's global markets. Information systems specialists can learn from logisticians. In a manner similar to logistics management, information logistics is concerned with the delivery of the right data, to the ring customer, at the right time. As such, information systems are integral components of the information logistics system charged with providing customers with accurate, timely, cost-effective, and useful information. Information logistics is a management style and is composed of elements similar to those associated with the traditional logistics activity: inventory management (data resource management), facilities management (distributed, centralized and decentralized information systems), communications (participative design and joint application development methodologies), unitization (input/output system design, i.e., packaging or formatting of the information), transportations (voice, data, image, and video communication systems

Information Security Service Branding – beyond information security awareness

Directory of Open Access Journals (Sweden)

Rahul Rastogi

2012-12-01

Full Text Available End-users play a critical role in the effective implementation and running of an information security program in any organization. The success of such a program depends primarily on the effective implementation and execution of associated information security policies and controls and the resultant behavior and actions of end-users. However, end-users often have negative perception of information security in the organization and exhibit non-compliance. In order to improve compliance levels, it is vital to improve the image of information security in the minds of end-users. This paper borrows the concepts of brands and branding from the domain of marketing to achieve this objective and applies these concepts to information security. The paper also describes a process for creating the information security service brand in the organization.

Core information sets for informed consent to surgical interventions: baseline information of importance to patients and clinicians.

Main, Barry G; McNair, Angus G K; Huxtable, Richard; Donovan, Jenny L; Thomas, Steven J; Kinnersley, Paul; Blazeby, Jane M

2017-04-26

Consent remains a crucial, yet challenging, cornerstone of clinical practice. The ethical, legal and professional understandings of this construct have evolved away from a doctor-centred act to a patient-centred process that encompasses the patient's values, beliefs and goals. This alignment of consent with the philosophy of shared decision-making was affirmed in a recent high-profile Supreme Court ruling in England. The communication of information is central to this model of health care delivery but it can be difficult for doctors to gauge the information needs of the individual patient. The aim of this paper is to describe 'core information sets' which are defined as a minimum set of consensus-derived information about a given procedure to be discussed with all patients. Importantly, they are intended to catalyse discussion of subjective importance to individuals. The model described in this paper applies health services research and Delphi consensus-building methods to an idea orginally proposed 30 years ago. The hypothesis is that, first, large amounts of potentially-important information are distilled down to discrete information domains. These are then, secondly, rated by key stakeholders in multiple iterations, so that core information of agreed importance can be defined. We argue that this scientific approach is key to identifying information important to all stakeholders, which may otherwise be communicated poorly or omitted from discussions entirely. Our methods apply systematic review, qualitative, survey and consensus-building techniques to define this 'core information'. We propose that such information addresses the 'reasonable patient' standard for information disclosure but, more importantly, can serve as a spring board for high-value discussion of importance to the individual patient. The application of established research methods can define information of core importance to informed consent. Further work will establish how best to incorporate

2016-02-01

Full Text Available One of the important factors that contribute to agricultural development is information. As such agricultural extension workers that link agricultural agencies to the farmers must have adequate and up-to-date information about agricultural practices before they could inform, educate and train the farmers in method and techniques of farming. This study aims to determine the types of information needed by agricultural extension workers; to determine the sources of information used by the agricultural extension workers; and to determine the comparison between types of information with information sources used by agricultural extension workers. The present study was a descriptive study using a survey design and conducted at Daerah Istimewa Yogyakarta (DIY Province. The populations of the study consists 181 agricultural extension workers divisible in the district level, namely Sleman, Kulon Progo, Gunung Kidul dan Bantul. Sampling procedure in this study used cluster sampling. The method for gathering data from the respondents is based on a structured questionnaire. Descriptive statistics was to describe the characteristics of the respondents and the dependent variables of the study. As a result, most of agricultural extension workers strongly needed the innovation information in seeking information followed by extension service information and extension role information. The result of information sources used by agricultural extension worker for extension service information, innovation information and extension role information indicates that agricultural extension workers used interpersonal source. Most of them never sought information use Internet, they use radio more frequently than television and video, agricultural extension worker also used mass media as information source.

How social information affects information search and choice in probabilistic inferences.

Science.gov (United States)

Puskaric, Marin; von Helversen, Bettina; Rieskamp, Jörg

2018-01-01

When making decisions, people are often exposed to relevant information stemming from qualitatively different sources. For instance, when making a choice between two alternatives people can rely on the advice of other people (i.e., social information) or search for factual information about the alternatives (i.e., non-social information). Prior research in categorization has shown that social information is given special attention when both social and non-social information is available, even when the social information has no additional informational value. The goal of the current work is to investigate whether framing information as social or non-social also influences information search and choice in probabilistic inferences. In a first study, we found that framing cues (i.e., the information used to make a decision) with medium validity as social increased the probability that they were searched for compared to a task where the same cues were framed as non-social information, but did not change the strategy people relied on. A second and a third study showed that framing a cue with high validity as social information facilitated learning to rely on a non-compensatory decision strategy. Overall, the results suggest that social in comparison to non-social information is given more attention and is learned faster than non-social information. Copyright © 2017 Elsevier B.V.

Towards Information Lasers

Full Text Available Recently, the methods of quantum theory (QT, especially quantum information and probability, started to be widely applied outside of physics: in cognitive, social and political sciences, psychology, economics, finances, decision making, molecular biology and genetics. Such models can be called quantum-like, in contrast to real quantum physical cognitive and biological models. Quantum-like means that only the information and probability structures of QT are explored. This approach matches the information interpretation of QT well (e.g., Zeilinger and Brukner, Fuchs and Mermin, D’Ariano, as well as the informational viewpoint on physics in general (e.g., Wheeler’s “it from bit” paradigm. In this paper, we propose a quantum-like model of an information laser by precessing the assumptions on the structure of state spaces of information processors, “information atoms” (i-atoms and information fields. The basic assumption is the discrete structure of state spaces related to quantization of an information analog of energy. To analyze a possible structure of the state space of i-atoms leading to the possibility to create information lasers, we have to develop a purely information version of quantum thermodynamics. We did this by placing the main attention on the derivation of the conditions for the equilibrium of information exchange between i-atoms and a quantized information field.

2000-01-01

Current information technology is centered on the internet and changes our daily working pattern, particularly with multimedia information. Rapid development of information processing hardware and software has enabled us to deploy multimedia information management system of low hit counts and small amount of information volume on the desktop computer and publish multimedia information directly to the workgroup intranet with no particular additional hardware and software. Success of the timely development of the information system depends on the adoption of the proper direction and scale of information technology. The nuclear control mainly consists of safeguards, physical protection and export/import control. This paper provides an investigation on the application of openly available multiple media information to the nuclear control information management system. Information system with spatial map, image data including satellite imagery, audio, and video makes users easy to understand the current status and communicate each other easily. The Digital Terrain Elevation Data (DTED) Level 0 of the U.S. NIMA (National Imagery and Mapping Agency) is used as a base map. The multimedia information system is mainly built with Microsoft PowerPoint 2000 and Office Web component. A database with the second normal form was applied to the Office Web component. The importance of the information security was stressed

Full Text Available Quattro anni fa Paul Virilio scriveva "Città panico" definendo la città contemporanea come “la più grande catastrofe del ventesimo secolo”. La sua analisi fa riferimento alle conseguenze sia politiche che spaziali di una velocità del progresso tecnologico e scientifico che aveva raggiunto ritmi così elevati da vanificare il senso stesso di quella sovranità territoriale che dava consistenza e materia allo stato di diritto. Lo stato sarebbe ora sospeso in una sorta di alla massa e all’energia – della materia. In un processo di continua dematerializzazione della “assenza di gravità”cinematica dominata dall’informazione, quale terza dimensione – oltre sostanza urbana sotto l’effetto dei nuovi media, sostiene Virilio, la prevalenza della natura effimera dell’informazione sconvolge i nostri stessi parametri di percezione del mondo, presentato, piuttosto che rappresentato, attraverso le interfacce che accessoriano le nostre vite, secondo riferimenti alterati da una vera e propria guerra al reale ad opera della comunicazione audiovisiva.

Major projection studies by international organizations and senior analysts have been compared with reference to individual key parameters (population, energy demand/supply, resources, technology, emissions and global warming) to understand trends and implications of the different scenarios. Then, looking at the long term (i.e., 2050 and beyond), parameters and trends have been compared together to understand and quantify whether and when possible crisis or market turbulence might occur due to shortage of resources or environmental problems. [Italian] Viene presentato un confronto degli scenari energetici di lungo termine formulati dalle agenzie internazionali e dai maggiori analisti del settore con particolare riferimento alla evoluzione di specifici parametri quali sviluppo demografico, domanda e offerta di energia, risorse energetiche, sviluppo tecnologico, emissioni e relativi cambiamenti climatici. L'evoluzione e l'interdipendenza dei singoli aspetti vengono analizzate al fine di individuare la possibile evenienza di crisi o turbolenze dei mercati energetici indotte da carenza di risorse o da problemi ambientali.

The Generalization of Mutual Information as the Information between a Set of Variables: The Information Correlation Function Hierarchy and the Information Structure of Multi-Agent Systems

Science.gov (United States)

Wolf, David R.

2004-01-01

The topic of this paper is a hierarchy of information-like functions, here named the information correlation functions, where each function of the hierarchy may be thought of as the information between the variables it depends upon. The information correlation functions are particularly suited to the description of the emergence of complex behaviors due to many- body or many-agent processes. They are particularly well suited to the quantification of the decomposition of the information carried among a set of variables or agents, and its subsets. In more graphical language, they provide the information theoretic basis for understanding the synergistic and non-synergistic components of a system, and as such should serve as a forceful toolkit for the analysis of the complexity structure of complex many agent systems. The information correlation functions are the natural generalization to an arbitrary number of sets of variables of the sequence starting with the entropy function (one set of variables) and the mutual information function (two sets). We start by describing the traditional measures of information (entropy) and mutual information.

Nuclear Information Democratization

International Nuclear Information System (INIS)

Savić, Dobrica

2013-01-01

Nuclear information (Nl) interests people for many reasons, with energy supply, safety, and security being at the top of the list. Democratizing nuclear information has its roots in the growth of a knowledge-based economy, the knowledge worker as a user of nuclear information, developments in information and communication technologies (ICT), and the impact of internet growth. Results of democratization are apparent in the process of information creation, in how nuclear information is distributed and accessed, and in the conditions for using the information found. The International Nuclear Information System (INIS) both reflects and contributes to these trends. Nuclear information falls under the overall umbrella of scientific and technical information (STI). It is highly specialized, but it follows general principles and trends of STI. The world of STI has its own culture and its own long-established rules of use and existence. These have brought us many inventions and improvements, introduced important technological changes, and made our lives and work much easier and more pleasurable. However, the world is constantly changing, and the traditional closed STI environment, including the world of nuclear information, is not keeping up with today’s changes. (author)

Looking out an office window or exploring a community park, one can easily see the tremendous challenges that biological information presents the computer science community. Biological information varies in format and content depending whether or not it is information pertaining to a particular species (i.e. Brown Tree Snake), or a specific ecosystem, which often includes multiple species, land use characteristics, and geospatially referenced information. The complexity and uniqueness of each individual species or ecosystem do not easily lend themselves to today's computer science tools and applications. To address the challenges that the biological enterprise presents the National Biological Information Infrastructure (NBII) (http://www.nbii.gov) was established in 1993. The NBII is designed to address these issues on a National scale within the United States, and through international partnerships abroad. This paper discusses current computer science efforts within the National Biological Information Infrastructure Program and future computer science research endeavors that are needed to address the ever-growing issues related to our Nation's biological concerns.

Full Text Available The information presented through visualization help the Information Retrieval System (IRS to reach its main goal: to retrieve relevant information that meets the informational needs of its users. The objective of this article is to describe and analyze techniques proposed by the Information Visualization area and interface models discussed in Information Science Literature, which applied to graphical interface construction would facilitate the appropriation of information by the users of IRS and would help them to search, browse and retrieve information. The methodology consists of a literature review focusing on the potential contribution of the visual representation of information in the development of user-friendly interfaces to IRS, as well as identification and analyses of visualizations used as interfaces by IRS. The use of visualizations is of great importance in the communication between SRI and users, because the information presented through visual representation are better understood by user and allow the discovery of new knowledge.

Spacetime information

International Nuclear Information System (INIS)

Hartle, J.B.

1995-01-01

In usual quantum theory, the information available about a quantum system is defined in terms of the density matrix describing it on a spacelike surface. This definition must be generalized for extensions of quantum theory which neither require, nor always permit, a notion of state on a spacelike surface. In particular, it must be generalized for the generalized quantum theories appropriate when spacetime geometry fluctuates quantum mechanically or when geometry is fixed but not foliable by spacelike surfaces. This paper introduces a four-dimensional notion of the information available about a quantum system's boundary conditions in the various sets of decohering, coarse-grained histories it may display. This spacetime notion of information coincides with the familiar one when quantum theory is formulable in terms of states on spacelike surfaces but generalizes this notion when it cannot be so formulated. The idea of spacetime information is applied in several contexts: When spacetime geometry is fixed the information available through alternatives restricted to a fixed spacetime region is defined. The information available through histories of alternatives of general operators is compared to that obtained from the more limited coarse grainings of sum-over-histories quantum mechanics that refer only to coordinates. The definition of information is considered in generalized quantum theories. We consider as specific examples time-neutral quantum mechanics with initial and final conditions, quantum theories with nonunitary evolution, and the generalized quantum frameworks appropriate for quantum spacetime. In such theories complete information about a quantum system is not necessarily available on any spacelike surface but must be searched for throughout spacetime. The information loss commonly associated with the ''evolution of pure states into mixed states'' in black hole evaporation is thus not in conflict with the principles of generalized quantum mechanics

Information barriers

Fuller, J.L.; Wolford, J.

2001-01-01

Full text: An information barrier (IB) consists of procedures and technology that prevent the release of sensitive information during a joint inspection of a sensitive nuclear item, and provides confidence that the measurement system into which it has been integrated functions exactly as designed and constructed. Work in the U.S. on radiation detection system information barriers dates back at least to 1990, even though the terminology is more recent. In January 1999 the Joint DoD-DOE Information Barrier Working Group was formed in the United States to help coordinate technical efforts related to information barrier R and D. This paper presents an overview of the efforts of this group, by its Chairs, as well as recommendations for further information barrier R and D. Progress on the demonstration of monitoring systems containing IBs is also provided. From the U.S. perspective, the basic, top-level functional requirements for the information barrier portion of an integrated radiation signature-information barrier inspection system are twofold: The host must be assured that his classified information is protected from disclosure to the inspecting party; and The inspecting party must be confident that the integrated inspection system measures, processes, and presents the radiation-signature-based measurement conclusion in an accurate and reproducible manner. It is the position of the United States that in the absence of any agreement to share classified nuclear weapons design information in the conduct of an inspection regime, the requirement to protect host country classified warhead design information is paramount and admits no tradeoff versus the confidence provided to the inspecting party in the accuracy and reproducibility of the measurements. The U.S. has reached an internal consensus on several critical design elements that define a general standard for radiation signature information barrier design. These criteria have stood the test of time under intense

Delaying information search

Full Text Available In three studies, we examined factors that may temporarily attenuate information search. People are generally curious and dislike uncertainty, which typically encourages them to look for relevant information. Despite these strong forces that promote information search, people sometimes deliberately delay obtaining valuable information. We find they may do so when they are concerned that the information might interfere with future pleasurable activities. Interestingly, the decision to search or to postpone searching for information is influenced not only by the value and importance of the information itself but also by well-being maintenance goals related to possible detrimental effects that negative knowledge may have on unrelated future plans.

To assess heath literacy, health information seeking, and trust in health-related information among Haitian immigrants seen in primary care. Health literacy was measured by the Brief Health Literacy Screen (BHLS); items on health information use were from the 2007 Health Information National Trends Survey. BHLS scores differed according to age, education, and survey language. Participants with lower levels of health literacy tended to be more likely to place "a lot" or "some" trust in family and friends and religious organizations and leaders as sources of information about health or medical topics. Constructing a culturally-tailored and appropriate intervention regarding health promotion requires understanding how the population accesses and conveys health information.

Multitasking information behavior, information task switching and anxiety: An exploratory study

International Nuclear Information System (INIS)

Alexopoulou, Peggy; Kotsopoulou, Anastasia

2015-01-01

Multitasking information behavior involves multiple forms of information searching such as library and Web search. Few researchers, however, have explored multitasking information behavior and information task switching in libraries in conjunction with psychological variables. This study explored this behavior in terms of anxiety under time pressure. This was an exploratory case study. Participant searched information for three unrelated everyday life information topics during a library visit, in a timeframe of one hour. The data collection tools used were: diary, observation, interview, and the State-Trait Anxiety Inventory test. Participant took the Trait-anxiety test before the library visit to measure anxiety level as a personal characteristic. She also took State-anxiety test before, during and after the library visit to measure anxiety levels regarding the information seeking behavior. The results suggested that participant had high levels of anxiety at the beginning of the multitasking information behavior. The reason for that was the concern about the performance as well as the identification of the right resources. During the multitasking information behavior, participant still had anxiety to find the right information. The levels of anxiety, however, were less due to library’s good organized structure. At the end of the information seeking process, the levels of anxiety dropped significant and therefore calm and safety returned. Finally, participant searched information for topics that were more important and for which she had prior knowledge When people, under time pressure, have access to well organized information, the levels of anxiety might decrease

The data collection tools used were: diary, observation, interview, and the State-Trait Anxiety Inventory test. Participant took the Trait-anxiety test before the library visit to measure anxiety level as a personal characteristic. She also took State-anxiety test before, during and after the library visit to measure anxiety levels regarding the information seeking behavior. The results suggested that participant had high levels of anxiety at the beginning of the multitasking information behavior. The reason for that was the concern about the performance as well as the identification of the right resources. During the multitasking information behavior, participant still had anxiety to find the right information. The levels of anxiety, however, were less due to library’s good organized structure. At the end of the information seeking process, the levels of anxiety dropped significant and therefore calm and safety returned. Finally, participant searched information for topics that were more important and for which she had prior knowledge When people, under time pressure, have access to well organized information, the levels of anxiety might decrease.

Information and knowledge: an evolutionary framework for information science

Directory of Open Access Journals (Sweden)

Marcia J. Bates

2005-01-01

Full Text Available Background. Many definitions of information, knowledge, and data have been suggested throughout the history of information science. In this article, the objective is to provide definitions that are usable for the physical, biological, and social meanings of the terms, covering the various senses important to our field. Argument. Information 1 is defined as the pattern of organization of matter and energy. Information 2 is defined as some pattern of organization of matter and energy that has been given meaning by a living being. Knowledge is defined as information given meaning and integrated with other contents of understanding. Elaboration. The approach is rooted in an evolutionary framework; that is, modes of information perception, processing, transmission, and storage are seen to have developed as a part of the general evolution of members of the animal kingdom. Brains are expensive for animals to support; consequently, efficient storage, including, particularly, storage at emergent levels-for example, storing the concept of chair, rather than specific memories of all chairs ever seen, is powerful and effective for animals. Conclusion. Thus, rather than being reductionist, the approach taken demonstrates the fundamentally emergent nature of most of what higher animals and human beings, in particular, experience as information.

Types of Lexicographical Information Needs and their Relevance for Information Science

Directory of Open Access Journals (Sweden)

Bergenholtz, Henning

2017-09-01

Full Text Available In some situations, you need information in order to solve a problem that has occurred. In information science, user needs are often described through very specific examples rather than through a classification of situation types in which information needs occur. Furthermore, information science often describes general human needs, typically with a reference to Maslow's classification of needs (1954, instead of actual information needs. Lexicography has also focused on information needs, but has developed a more abstract classification of types of information needs, though (until more recent research into lexicographical functions with a particular interest in linguistic uncertainties and the lack of knowledge and skills in relation to one or several languages. In this article, we suggest a classification of information needs in which a tripartition has been made according to the different types of situations: communicative needs, cognitive needs, and operative needs. This is a classification that is relevant and useful in general in our modern information society and therefore also relevant for information science, including lexicography.

2010-04-01

The need for effective communication and handling of secondary care information in general practices is paramount. To explore practice processes on receiving secondary care correspondence in a way that integrates the information needs and perceptions of practice staff both clinical and administrative. Qualitative study using semi-structured interviews with a wide range of practice staff (n = 36) in nine practices in the Northwest of England. Analysis was based on the framework approach using N-Vivo software and involved transcription, familiarization, coding, charting, mapping and interpretation. The 'information processing model' was developed to describe the six stages involved in practice processing of secondary care information. These included the amendment or updating of practice records whilst simultaneously or separately actioning secondary care recommendations, using either a 'one-step' or 'two-step' approach, respectively. Many factors were found to influence each stage and impact on the continuum of patient care. The primary purpose of processing secondary care information is to support patient care; this study raises the profile of information flow and usage within practices as an issue requiring further consideration.

Disclosure of information and informed consent: ethical and practical considerations.

Science.gov (United States)

Steinberg, Avraham

2009-12-01

Disclosure of information and informed consent are relatively new concepts in the patient-physician relationship. They are based primarily on the principle of autonomy and they have many favorable practical advantages. However, the practical implementation of these requirements is fraught with difficulties, some of which can cause harm to the patient or be obstacles in fulfilling the moral obligation of beneficence. This is particularly true when disclosure of information and informed consent are done by physicians in a defensive way for fear of malpractice suits. The most ethically defensible approach is to tailor and navigate the information according to the needs and desires of each individual patient in a sensitive and empathic manner. The informed consent should be a process of mutually shared responsibility by the patient and the physician, ensuring adequate and relevant information that is well comprehended by the individual patient, and is used correctly for his or her decision making.

Information retrieval pathways for health information exchange in multiple care settings.

Kierkegaard, Patrick; Kaushal, Rainu; Vest, Joshua R

2014-11-01

To determine which health information exchange (HIE) technologies and information retrieval pathways healthcare professionals relied on to meet their information needs in the context of laboratory test results, radiological images and reports, and medication histories. Primary data was collected over a 2-month period across 3 emergency departments, 7 primary care practices, and 2 public health clinics in New York state. Qualitative research methods were used to collect and analyze data from semi-structured interviews and participant observation. The study reveals that healthcare professionals used a complex combination of information retrieval pathways for HIE to obtain clinical information from external organizations. The choice for each approach was setting- and information-specific, but was also highly dynamic across users and their information needs. Our findings about the complex nature of information sharing in healthcare provide insights for informatics professionals about the usage of information; indicate the need for managerial support within each organization; and suggest approaches to improve systems for organizations and agencies working to expand HIE adoption.

Identification of energy information needs and existing information sources for Pennsylvania

Energy Technology Data Exchange (ETDEWEB)

Wisch, A.; Kunzier, J.; Limaye, D.; Orlando, J.

1976-01-01

Through use of a comprehensive interviewing schedule designed to elicit information needs from state policymakers, this study has shown a statewide need for a workable energy information network. As a counterpoint to this needs survey, it was also demonstrated that many of the components of such an information base already are available at the state and Federal levels. In order to assure that Pennsylvania's decision makers have access to this required information in a current and useful format at a minimal cost, this study has suggested a three-pronged action program: (1) In order to construct a workable energy information network for use by the Commonwealth, a liaison should be established with the Governor's Energy Council and the various national and regional energy information sources as cited in this report. (2) An information directory on State, Federal and private sources should be maintained and distributed on a continuing basis. An assessment of each source should be included with information on ease of access and relevance of the source to Pennsylvania. (3) After an information need is unable to be met through use of (1) the state energy information network and/or (2) the state energy information directory, effort should be initiated to satisfy that specific requirement.

Defining information need in health - assimilating complex theories derived from information science.

Science.gov (United States)

Ormandy, Paula

2011-03-01

Key policy drivers worldwide include optimizing patients' roles in managing their care; focusing services around patients' needs and preferences; and providing information to support patients' contributions and choices. The term information need penetrates many policy documents. Information need is espoused as the foundation from which to develop patient-centred or patient-led services. Yet there is no clear definition as to what the term means or how patients' information needs inform and shape information provision and patient care. The assimilation of complex theories originating from information science has much to offer considerations of patient information need within the context of health care. Health-related research often focuses on the content of information patients prefer, not why they need information. This paper extends and applies knowledge of information behaviour to considerations of information need in health, exposing a working definition for patient information need that reiterates the importance of considering the patient's goals and understanding the patient's context/situation. A patient information need is defined as 'recognition that their knowledge is inadequate to satisfy a goal, within the context/situation that they find themselves at a specific point in the time'. This typifies the key concepts of national/international health policy, the centrality and importance of the patient. The proposed definition of patient information need provides a conceptual framework to guide health-care practitioners on what to consider and why when meeting the information needs of patients in practice. This creates a solid foundation from which to inform future research. © 2010 The Author. Health Expectations © 2010 Blackwell Publishing Ltd.

The present paper begins by giving a theoretical treatment for the nuclear reactor period. The conventional method of measuring the period is analysed and some previously developed digital methods are described. The paper criticises the latter, pointing out some deficiencies which the proposed process is able to eliminate. All errors connected with this process are also analysed. The paper presents suitable solutions to reduce them to a minimum. The total error is found to he less than the error presented by the other methods described. A digital period meter is designed with memory resources and an automatic scaler changer. Integrated circuits specifications are used in it. Real time experiments with nuclear reactors were made in order to check te validity of the method. The data acquired were applied to a simulated digital period meter implemented in a general purpose computer. The nuclear part of the work was developed at the 'Comissao Nacional de Energia Nuclear' and the simulation work was dane at the 'Departamento de Calculo Cientifico' of COPPE, which also advised the author in the completion of this thesis.

Digital Information and Value

Directory of Open Access Journals (Sweden)

Paul Walton

2015-11-01

Full Text Available Digital information changes the ways in which people and organisations interact. This paper examines the nature of this change in the context of the author’s Model for Information (MfI. It investigates the relationship between outcomes and value, selection processes and some attributes of information and explores how this relationship changes in the move from analogue to digital information. Selection processes shape the evolution of information ecosystems in which conventions are established for the ways in which information is used. The conventions determine norms for information friction and information quality as well as the sources of information and channels used. Digital information reduces information friction, often dramatically, and changes information quality. The increasing use of analytics in business increasingly delivers predictive or prescriptive digital information. These changes are happening faster than information ecosystem conventions can change. The relationships established in the paper enable an analysis of, and guide changes to, these conventions enabling a more effective use of digital information.

Information carriers and (reading them through) information theory in quantum chemistry.

Science.gov (United States)

Geerlings, Paul; Borgoo, Alex

2011-01-21

This Perspective discusses the reduction of the electronic wave function via the second-order reduced density matrix to the electron density ρ(r), which is the key ingredient in density functional theory (DFT) as a basic carrier of information. Simplifying further, the 1-normalized density function turns out to contain essentially the same information as ρ(r) and is even of preferred use as an information carrier when discussing the periodic properties along Mendeleev's table where essentially the valence electrons are at stake. The Kullback-Leibler information deficiency turns out to be the most interesting choice to obtain information on the differences in ρ(r) or σ(r) between two systems. To put it otherwise: when looking for the construction of a functional F(AB) = F[ζ(A)(r),ζ(B)(r)] for extracting differences in information from an information carrier ζ(r) (i.e. ρ(r), σ(r)) for two systems A and B the Kullback-Leibler information measure ΔS is a particularly adequate choice. Examples are given, varying from atoms, to molecules and molecular interactions. Quantum similarity of atoms indicates that the shape function based KL information deficiency is the most appropriate tool to retrieve periodicity in the Periodic Table. The dissimilarity of enantiomers for which different information measures are presented at global and local (i.e. molecular and atomic) level leads to an extension of Mezey's holographic density theorem and shows numerical evidence that in a chiral molecule the whole molecule is pervaded by chirality. Finally Kullback-Leibler information profiles are discussed for intra- and intermolecular proton transfer reactions and a simple S(N)2 reaction indicating that the theoretical information profile can be used as a companion to the energy based Hammond postulate to discuss the early or late transition state character of a reaction. All in all this Perspective's answer is positive to the question of whether an even simpler carrier of

Information-preserving structures: A general framework for quantum zero-error information

International Nuclear Information System (INIS)

Blume-Kohout, Robin; Ng, Hui Khoon; Poulin, David; Viola, Lorenza

2010-01-01

Quantum systems carry information. Quantum theory supports at least two distinct kinds of information (classical and quantum), and a variety of different ways to encode and preserve information in physical systems. A system's ability to carry information is constrained and defined by the noise in its dynamics. This paper introduces an operational framework, using information-preserving structures, to classify all the kinds of information that can be perfectly (i.e., with zero error) preserved by quantum dynamics. We prove that every perfectly preserved code has the same structure as a matrix algebra, and that preserved information can always be corrected. We also classify distinct operational criteria for preservation (e.g., 'noiseless','unitarily correctible', etc.) and introduce two natural criteria for measurement-stabilized and unconditionally preserved codes. Finally, for several of these operational criteria, we present efficient (polynomial in the state-space dimension) algorithms to find all of a channel's information-preserving structures.

Public information strategies

Waldahl, R.

1995-01-01

The Chernobyl accident in 1986 uncovered serious information problems in many Western countries, and started a debate on crisis communication and information strategies in relation to radiation danger in society. The information problem focuses on four main perspectives. The first is related to information as a persuasion process in which an efficient strategy would influence both the public's knowledge of radiation danger, their attitude towards it and their behaviour. The second perspective calls attention to the importance of the different elements of the information process. How important are different characteristics of the information source; the message itself, and the receiver? The third perspective concentrates on different types of information. What is this issue all about, why is the situation as it is, and how should people behave to protect themselves? The fourth perspective points to the various phases of a crisis. The information needed is obviously not the same in the period before a crisis emerges when no one knows what is going to happen, in the warning period when one knows that something may happen, and during the crisis itself.

Teaching information seeking

2006-01-01

Full Text Available Introduction. The article argues for a closer association between information seeking research and the practices of teaching information seeking. Findings are presented from a research project on information seeking, didactics and learning (IDOL investigating librarians' and teachers' experiences of teaching information seeking. Method. Thirteen teachers and five librarians, teaching 12-19 year-old students in three schools, participated. Forty-five interviews were conducted over a period of three years. Analysis. The IDOL project adopted a phenomenographic approach with the purpose of describing patterns of variation in experiences. The findings were also analysed by way of relating them to four competing approaches to the mediation of information literacy. Results. A gap was identified between experiences of teaching content that focused on sources and order, and experiences of assessment criteria applied to students' work that focused on the importance of correct facts and the analysis of information. These findings indicate a highly restricted range of teaching contents when compared with the four theoretical approaches to the mediation of information literacy. Conclusion. Teaching information seeking might be enhanced by a wider repertoire of contents reflecting more varied theoretical understanding developed in information seeking research, particularly as regards the importance of content and context related to user perspectives.

INFORMATION SOCIETY: the instrumental logic of access to information and knowledge

Full Text Available The idea of an information society cannot dissociate from the socio-productive structure. In contemporary capitalism, the immaterial is a preponderant factor in the productive model. Due to the informational field becomes essential in the productive-economic, scientific and cultural process. Information and knowledge characterize as intrinsic factors to the productive reconfiguration to capitalism, in which the rationalization and appropriation is shaped: Science and Technology, innovation and appropriation of cooperation and social relations. For this reason, their proper operation and instrumentality are very important for the creation of surplus value. This article presents a brief critical analysis of the term information society and highlights the historicalideological plan from which it elaborated. We introduces the concepts of "Knowledge Economy" and "Information Regime". The methodology used is of bibliographic-exploratory nature. As a conclusion, it reflects on the importance of the dissemination of information and knowledge as a process of democratization. The operationalization of scientific information and control methods that seek to capture information and knowledge, and thus generate surplus value, information technologies and citizenship have put in the horizon possible actions and capacities of transformation, even if impartial and unstable.

Unlike physics, however, information science has yet to develop a unified theory that unites the contradictory conceptions of its essential theoretical object.

Information density converges in dialogue: Towards an information-theoretic model.

Science.gov (United States)

Xu, Yang; Reitter, David

2018-01-01

The principle of entropy rate constancy (ERC) states that language users distribute information such that words tend to be equally predictable given previous contexts. We examine the applicability of this principle to spoken dialogue, as previous findings primarily rest on written text. The study takes into account the joint-activity nature of dialogue and the topic shift mechanisms that are different from monologue. It examines how the information contributions from the two dialogue partners interactively evolve as the discourse develops. The increase of local sentence-level information density (predicted by ERC) is shown to apply to dialogue overall. However, when the different roles of interlocutors in introducing new topics are identified, their contribution in information content displays a new converging pattern. We draw explanations to this pattern from multiple perspectives: Casting dialogue as an information exchange system would mean that the pattern is the result of two interlocutors maintaining their own context rather than sharing one. Second, we present some empirical evidence that a model of Interactive Alignment may include information density to explain the effect. Third, we argue that building common ground is a process analogous to information convergence. Thus, we put forward an information-theoretic view of dialogue, under which some existing theories of human dialogue may eventually be unified. Copyright © 2017 Elsevier B.V. All rights reserved.

Information Infrastructure, Information Environments, and Long-Term Collaboration

Science.gov (United States)

Baker, K. S.; Pennington, D. D.

2009-12-01

Information infrastructure that supports collaborative science is a complex system of people, organizational arrangements, and tools that require co-management. Contemporary studies are exploring how to establish and characterize effective collaborative information environments. Collaboration depends on the flow of information across the human and technical system components through mechanisms that create linkages, both conceptual and technical. This transcends the need for requirements solicitation and usability studies, highlighting synergistic interactions between humans and technology that can lead to emergence of group level cognitive properties. We consider the ramifications of placing priority on establishing new metaphors and new types of learning environments located near-to-data-origin for the field sciences. In addition to changes in terms of participant engagement, there are implications in terms of innovative contributions to the design of information systems and data exchange. While data integration occurs in the minds of individual participants, it may be facilitated by collaborative thinking and community infrastructure. Existing learning frameworks - from Maslow’s hierarchy of needs to organizational learning - require modification and extension if effective approaches to decentralized information management and systems design are to emerge. Case studies relating to data integration include ecological community projects: development of cross-disciplinary conceptual maps and of a community unit registry.

Full Text Available As information literacy has become a necessity for active involvement in the life of 21st century, it has been set as one of the aims of reformed grammar school. The schoollibrary, through its programme of library information ski1ls, can cosiderably influence students' independence at searching, working with or learning from information sources. The programme of Iibrary & information skilIs has been designed on current knowledge of the developing information literacy, implemented with the assistance of teachers and integrated into the teaching process.The pre-test, the experiment and the post-test of the experimental group (EG and the control group (CG, support the hypothesis that an implemented library information ski1ls programe has a major effect on the independence of the students. The Hest has shown that the knowledge of the students in the EG after the experiment and after practical dealing with problems has changed. The t-test has also proved that the difference in the knowledge of the students in the EG is statistically significant, whi1e the knowledge of the students in the CG, who have not carried out the programme, has also changed, but the difference in the knowledge is not statistically significant.

Personal anticipated information need

H. Bruce

2005-01-01

Full Text Available Background. The role of personal information collections is a well known feature of personal information management. The World Wide Web has introduced to such collections ideas such as filing Web pages or noting their existence in 'Bookmarks' and 'Favourites'. Argument. It is suggested that personal information collections are created in anticipation of some future need for that information-personal, anticipated information need, which also underlies the design of formal information systems. Elaboration. Examination of the literature of information needs and information seeking behaviour leads to the formulation of five propositions that elaborate the concept of personal, anticipated information need. These propositions draw upon concepts such as uncertainty, predictability, sensitivity and the valuation of information sources. Conclusion. An individual's understanding of personal, anticipated information need and how this understanding guides the acquisition and management of personal information will determine the effectiveness of that collection.

Paul Walton

2014-09-01

Full Text Available This paper uses an approach drawn from the ideas of computer systems modelling to produce a model for information itself. The model integrates evolutionary, static and dynamic views of information and highlights the relationship between symbolic content and the physical world. The model includes what information technology practitioners call “non-functional” attributes, which, for information, include information quality and information friction. The concepts developed in the model enable a richer understanding of Floridi’s questions “what is information?” and “the informational circle: how can information be assessed?” (which he numbers P1 and P12.

The Internet information infrastructure: Terrorist tool or architecture for information defense?

Energy Technology Data Exchange (ETDEWEB)

Kadner, S.; Turpen, E. [Aquila Technologies Group, Albuquerque, NM (United States); Rees, B. [Los Alamos National Lab., NM (United States)

1998-12-01

The Internet is a culmination of information age technologies and an agent of change. As with any infrastructure, dependency upon the so-called global information infrastructure creates vulnerabilities. Moreover, unlike physical infrastructures, the Internet is a multi-use technology. While information technologies, such as the Internet, can be utilized as a tool of terror, these same technologies can facilitate the implementation of solutions to mitigate the threat. In this vein, this paper analyzes the multifaceted nature of the Internet information infrastructure and argues that policymakers should concentrate on the solutions it provides rather than the vulnerabilities it creates. Minimizing risks and realizing possibilities in the information age will require institutional activities that translate, exploit and convert information technologies into positive solutions. What follows is a discussion of the Internet information infrastructure as it relates to increasing vulnerabilities and positive potential. The following four applications of the Internet will be addressed: as the infrastructure for information competence; as a terrorist tool; as the terrorist`s target; and as an architecture for rapid response.

To assess the quality of the information that patients receive in the informed consent document signed prior to surgery. Cross-sectional study of a sample of cancer patients admitted for surgery at the University Hospital San Cecilio of Granada in 2011. After checking the inclusion criteria and obtaining their consent, demographic data were collected and procedure data, and a questionnaire «ad hoc» to assess the quality and comprehensiveness of the information provided in the informed consent. 150 patients were studied. The majority (109 over 150) said they had received sufficient information, in appropriate language, and had the opportunity to ask questions, but only 44.7% correctly answered three or more issues related to anesthesia. University education level, knowledge of the intervention, information about the anesthesia problems and appropriate language were associated. Although systematic informed consent was performed, half of the patients did not comprehend the anesthesia risks. Variables primarily related to the information received were associated with the quality of the response, but not with patient characteristics. Copyright © 2013 AEC. Published by Elsevier Espana.

Electromagnetic modeling of the rings of the squirrel cage of an induction motor; Modelado electromagnetico de los anillos de la jaula de ardilla de un motor de induccion

Energy Technology Data Exchange (ETDEWEB)

Limones Montoya, Juan Carlos

2004-03-15

An electromagnetic lineal model of a three-phase induction motor was developed in this thesis. The Finite element method in two dimensions was used. The model formulation takes into account the coupling with the stator wires and solid conductors of the rotor. In other words, the stator phases and squirrel-cage end-rings are considered in the model. The resulting set of electric-circuit and magnetic-field equations are solved simultaneously with the Incomplete Cholesky Bi-Conjugate Gradient Method using a matrix storage technique known as symmetric coordinate storage. The model was programmed in the C programming language. The magnetic field model is represented by the diffusion equation, which allows to compute the induced Eddy currents in the conducting material due to the sinusoidal stator excitation. The modelled induction motor has a rated power of 2.2 kW, 220 V, 9.6/11.0 A, 60 Hz and it can be operated at the speeds of 1750/1150 rpm. It is located in the Laboratorio de Propulsion at the Instituto Tecnologico de la Laguna. [Spanish] En este trabajo de tesis se desarrollo un modelo electromagnetico lineal de un motor de induccion trifasico utilizando el Metodo de Elemento Finito en dos dimensiones, en el cual se incluye la formulacion de sistemas acoplados para los conductores delgados y gruesos presentes en el estator y rotor respectivamente. Es decir, se incluyen en el modelo las fases de alimentacion y los anillos de cortocircuito del rotor de jaula de ardilla.

Antonio Florio

2009-11-01

Full Text Available After a concise introduction on the analysis of truth and meaning in philosophy of language two notions of information are grasped by the analysis of Situation Semantics and Situation Theory. The first is that of correlation, the second that of constraint; the latter is reducible to the former. More than that, the phenomenon of ";alethic nature of information"; is highlighted and the notion of ";being informative"; is pointed out. The difference between a meaning-oriented and an informational-oriented perspective of language is marked. Messages are recognized as being the atomic constituents of the informational perspective of language; the architecture of language is shown; and a praxiological-information perspective on the study of language is outlined.

The necessary information to distinguish a local inhomogeneous mass density field from its spatial average on a compact domain of the universe can be measured by relative information entropy. The Kullback–Leibler (KL) formula arises very naturally in this context, however, it provides a very complicated way to compute the mutual information between spatially separated but causally connected regions of the universe in a realistic, inhomogeneous model. To circumvent this issue, by considering a parametric extension of the KL measure, we develop a simple model to describe the mutual information which is entangled via the gravitational field equations. We show that the Tsallis relative entropy can be a good approximation in the case of small inhomogeneities, and for measuring the independent relative information inside the domain, we propose the Rényi relative entropy formula.

Informational analysis involving application of complex information system

The aim of the present research is performing an informal analysis for internal audit involving the application of complex information system based on fuzzy logic. The same has been applied in internal audit involving the integration of the accounting field into the information systems field. The technological advancements can provide improvements to the work performed by the internal audit. Thus we aim to find, in the complex information systems, priorities for the work of internal audit of a high importance Private Institution of Higher Education. The applied method is quali-quantitative, as from the definition of strategic linguistic variables it was possible to transform them into quantitative with the matrix intersection. By means of a case study, where data were collected via interview with the Administrative Pro-Rector, who takes part at the elaboration of the strategic planning of the institution, it was possible to infer analysis concerning points which must be prioritized at the internal audit work. We emphasize that the priorities were identified when processed in a system (of academic use). From the study we can conclude that, starting from these information systems, audit can identify priorities on its work program. Along with plans and strategic objectives of the enterprise, the internal auditor can define operational procedures to work in favor of the attainment of the objectives of the organization.

This document is the second of a planned four-volume work that comprehensively discusses the security classification of information. The main focus of Volume 2 is on the principles for classification of information. Included herein are descriptions of the two major types of information that governments classify for national security reasons (subjective and objective information), guidance to use when determining whether information under consideration for classification is controlled by the government (a necessary requirement for classification to be effective), information disclosure risks and benefits (the benefits and costs of classification), standards to use when balancing information disclosure risks and benefits, guidance for assigning classification levels (Top Secret, Secret, or Confidential) to classified information, guidance for determining how long information should be classified (classification duration), classification of associations of information, classification of compilations of information, and principles for declassifying and downgrading information. Rules or principles of certain areas of our legal system (e.g., trade secret law) are sometimes mentioned to .provide added support to some of those classification principles.

Full Text Available A unified definition of the phenomenon information is not possible at present, because of the enormous number of different views. The situation is increased by the 'Capurro‘s trilemma' which postulates the logical impossibility of a unified concept of information. There are two approaches in the literature, which aim to solve the trilemma. The first approach avoids collision with the trilemma through the introduction of a generalized parameter to form rules of language for information systems. The second approach is understood as a draft of a generalized understanding of information within a yet to be developed unified information science. This article presents the approach of understanding information as an instantaneous process, which effects changes in systems. These changes must be captured and reproduced by the organization of the system, otherwise they get lost by fluctuations. Information in this reductionist conception is possible in each system, under the assumption, that it has several stable states, which alternatively may be assumed by the system . The 'Capurro‘s trilemma' is negated.

Full Text Available This article briefly discusses various definitions and concepts of the so-called information society. The term information society has been proposed to refer to the post-industrial society in which information plays a pivotal role. The definitions that have been proposed over the years highlight five underlying characterisations of an information society: technological, economic, sociological, spatial, and cultural. This article discusses those characteristics. While the emergence of an information society may be just a figment of one’s imagination, the concept could be a good organising principle to describe and analyse the changes of the past 50 years and of the future in the 21st century.

During the reception of a piece of information, we are never passive. Depending on its origin and content, from our personal beliefs and convictions, we bestow upon this piece of information, spontaneously or after reflection, a certain amount of confidence. Too much confidence shows a degree of naivety, whereas an absolute lack of it condemns us as being paranoid. These two attitudes are symmetrically detrimental, not only to the proper perception of this information but also to its use. Beyond these two extremes, each person generally adopts an intermediate position when faced with the recep

In recent years we extended Shannon static statistical information theory to dynamic processes and established a Shannon dynamic statistical information theory, whose core is the evolution law of dynamic entropy and dynamic information. We also proposed a corresponding Boltzmman dynamic statistical information theory. Based on the fact that the state variable evolution equation of respective dynamic systems, i.e. Fokker-Planck equation and Liouville diffusion equation can be regarded as their information symbol evolution equation, we derived the nonlinear evolution equations of Shannon dynamic entropy density and dynamic information density and the nonlinear evolution equations of Boltzmann dynamic entropy density and dynamic information density, that describe respectively the evolution law of dynamic entropy and dynamic information. The evolution equations of these two kinds of dynamic entropies and dynamic informations show in unison that the time rate of change of dynamic entropy densities is caused by their drift, diffusion and production in state variable space inside the systems and coordinate space in the transmission processes; and that the time rate of change of dynamic information densities originates from their drift, diffusion and dissipation in state variable space inside the systems and coordinate space in the transmission processes. Entropy and information have been combined with the state and its law of motion of the systems. Furthermore we presented the formulas of two kinds of entropy production rates and information dissipation rates, the expressions of two kinds of drift information flows and diffusion information flows. We proved that two kinds of information dissipation rates (or the decrease rates of the total information) were equal to their corresponding entropy production rates (or the increase rates of the total entropy) in the same dynamic system. We obtained the formulas of two kinds of dynamic mutual informations and dynamic channel

Pregnant women should be provided with relevant and useful information to manage this specific period of their lives. Assessing information needs of this group is a prerequisite for providing this information. The aim of this study was to assess the information needs of pregnant women during their pregnancy and childbirth. This descriptive study was conducted on the pregnant women who attended antenatal clinics and obstetricians/gynaecologists' offices in Kerman, Iran, in 2015. Data were collected using a self-administered, valid and reliable questionnaire. A total of 400 women participated in the study. Most pregnant women needed information about care of the foetus (n = 344, 86%), physical and psychological complications after delivery (n = 333, 83%), development and growth of the foetus (n = 330, 82.5%), pregnancy nutrition (n = 327, 82%) and special tests during pregnancy (n = 326, 81.5%). They mostly (n = 195, 49%) looked for information when they were suffering from a disease or pregnancy complications. As pregnant women need extensive information to be able to take care of themselves and their babies, their information needs should be identified and taken into consideration when planning educational programmes for this group of women. © 2017 Health Libraries Group.

Successful application of adaptive management to rebuilding the Columbia Basin`s anadromous fish resources requires that available information and experience be organized and shared between numerous organizations and individuals. Much of this knowledge exists only in unpublished form in agency and individual files. Even that information which is published in the form of technical and contract reports receives only limited distribution and is often out of print and unavailable after a few years. Only a small fraction of the basin`s collective knowledge is captured in permanent and readily available databases and recognized journals. State, tribal, and federal fishery managers have recognize these information management problems and have committed to a program, the Coordinated Information System Project, to capture and share more easily the core data and other information upon which management decisions are based. That project is now completing the process of scoping and identification of information needs. Construction of prototype systems will begin in 1992. This report is one in a series of seven describing the results of the Coordinated Information on System scoping and needs identification phase.

The Identity of Information: How Deterministic Dependencies Constrain Information Synergy and Redundancy

Directory of Open Access Journals (Sweden)

Daniel Chicharro

2018-03-01

Full Text Available Understanding how different information sources together transmit information is crucial in many domains. For example, understanding the neural code requires characterizing how different neurons contribute unique, redundant, or synergistic pieces of information about sensory or behavioral variables. Williams and Beer (2010 proposed a partial information decomposition (PID that separates the mutual information that a set of sources contains about a set of targets into nonnegative terms interpretable as these pieces. Quantifying redundancy requires assigning an identity to different information pieces, to assess when information is common across sources. Harder et al. (2013 proposed an identity axiom that imposes necessary conditions to quantify qualitatively common information. However, Bertschinger et al. (2012 showed that, in a counterexample with deterministic target-source dependencies, the identity axiom is incompatible with ensuring PID nonnegativity. Here, we study systematically the consequences of information identity criteria that assign identity based on associations between target and source variables resulting from deterministic dependencies. We show how these criteria are related to the identity axiom and to previously proposed redundancy measures, and we characterize how they lead to negative PID terms. This constitutes a further step to more explicitly address the role of information identity in the quantification of redundancy. The implications for studying neural coding are discussed.

International cooperative information systems

Developing countries need mechanisms by which the information they generate themselves and development information from the rest of the world can be retrieved. The international cooperative information system is such a mechanism. Delegates to the Seminar on International Cooperative Information Systems were informed about various existing systems (INIS, AGRIS, INFOTERRA, TCDC/INRES, POPIN, DEVSIS, and INPADROC), some specialized information systems and services (CDS/ISIS and the Cassava Information Centre), and computer programs for information processing (INIS/AGRIS, CDS/ISIS, and MINISIS). The participants suggested some changes that should be made on both the national and the international levels to ensure that these systems meet the needs of developing countries more effectively.

Hu, Fengpei; Hu, Huan; Xu, Lian; Qin, Jungang

2013-02-01

Recognition of the gender of a face is important in social interactions. In the current study, the distribution of informative facial information was systematically examined during gender judgment using two methods, Bubbles and Focus windows techniques. Two experiments found that the most informative information was around the eyes, followed by the mouth and nose. Other parts of the face contributed to the gender recognition but were less important. The left side of the face was used more during gender recognition in two experiments. These results show mainly areas around the eyes are used for gender judgment and demonstrate perceptual asymmetry with a normal (non-chimeric) face.

Online Cancer Information Seeking: Applying and Extending the Comprehensive Model of Information Seeking.

Science.gov (United States)

Van Stee, Stephanie K; Yang, Qinghua

2017-10-30

This study applied the comprehensive model of information seeking (CMIS) to online cancer information and extended the model by incorporating an exogenous variable: interest in online health information exchange with health providers. A nationally representative sample from the Health Information National Trends Survey 4 Cycle 4 was analyzed to examine the extended CMIS in predicting online cancer information seeking. Findings from a structural equation model supported most of the hypotheses derived from the CMIS, as well as the extension of the model related to interest in online health information exchange. In particular, socioeconomic status, beliefs, and interest in online health information exchange predicted utility. Utility, in turn, predicted online cancer information seeking, as did information-carrier characteristics. An unexpected but important finding from the study was the significant, direct relationship between cancer worry and online cancer information seeking. Theoretical and practical implications are discussed.

An information theory-based approach to modeling the information processing of NPP operators

International Nuclear Information System (INIS)

Kim, Jong Hyun; Seong, Poong Hyun

2002-01-01

This paper proposes a quantitative approach to modeling the information processing of NPP operators. The aim of this work is to derive the amount of the information processed during a certain control task. The focus will be on i) developing a model for information processing of NPP operators and ii) quantifying the model. To resolve the problems of the previous approaches based on the information theory, i.e. the problems of single channel approaches, we primarily develop the information processing model having multiple stages, which contains information flows. Then the uncertainty of the information is quantified using the Conant's model, a kind of information theory

HEALTH RECORDS AND INFORMATION TECHNOLOGY IN SUPPORT OF EXCHANGE OF HEALTH INFORMATION

Directory of Open Access Journals (Sweden)

Jordan Deliversky

2017-05-01

Full Text Available The exchange of health information in conditions directly related to electronic environment is referred as health information technology. Usually the protection of personal health related data is comprised of various elements such as ways of information usage and access to sensitive health information. The protection of individually identifiable health information is possible with combination of measures. Protective measures include administrative, technical and physical elements. Through such protective measures is possible to ensure confidentiality, integrity and availability of the information, while at the same time could be guaranteed the prevention of unauthorized access. Sensitive records usually contain personal health information. Personal medical data requires high level of protection, as its content includes medical condition or diagnosis, where unauthorized access could have negative impact on one’s personal and professional life.

Local versus nonlocal information in quantum-information theory: Formalism and phenomena

International Nuclear Information System (INIS)

Horodecki, Michal; Horodecki, Ryszard; Synak-Radtke, Barbara; Horodecki, Pawel; Oppenheim, Jonathan; Sen, Aditi; Sen, Ujjwal

2005-01-01

In spite of many results in quantum information theory, the complex nature of compound systems is far from clear. In general the information is a mixture of local and nonlocal ('quantum') information. It is important from both pragmatic and theoretical points of view to know the relationships between the two components. To make this point more clear, we develop and investigate the quantum-information processing paradigm in which parties sharing a multipartite state distill local information. The amount of information which is lost because the parties must use a classical communication channel is the deficit. This scheme can be viewed as complementary to the notion of distilling entanglement. After reviewing the paradigm in detail, we show that the upper bound for the deficit is given by the relative entropy distance to so-called pseudoclassically correlated states; the lower bound is the relative entropy of entanglement. This implies, in particular, that any entangled state is informationally nonlocal - i.e., has nonzero deficit. We also apply the paradigm to defining the thermodynamical cost of erasing entanglement. We show the cost is bounded from below by relative entropy of entanglement. We demonstrate the existence of several other nonlocal phenomena which can be found using the paradigm of local information. For example, we prove the existence of a form of nonlocality without entanglement and with distinguishability. We analyze the deficit for several classes of multipartite pure states and obtain that in contrast to the GHZ state, the Aharonov state is extremely nonlocal. We also show that there do not exist states for which the deficit is strictly equal to the whole informational content (bound local information). We discuss the relation of the paradigm with measures of classical correlations introduced earlier. It is also proved that in the one-way scenario, the deficit is additive for Bell diagonal states. We then discuss complementary features of

Harnessing information technology to improve women's health information: evidence from Pakistan.

Science.gov (United States)

Zakar, Rubeena; Zakar, Muhammad Z; Qureshi, Shazia; Fischer, Florian

2014-09-04

More than half of Pakistani women are illiterate, marginalized, and experience myriad health problems. These women are also disadvantaged in terms of their restricted mobility and limited access to public space. Nonetheless, user-friendly information and communication technologies (ICTs) have opened up new opportunities to provide them with information that is essential for their health and well-being. We established an Information and Communication Centre (ICC) in a village in Sialkot (Pakistan) on a pilot basis in 2009. The basic philosophy of the ICC was to provide women with health-related information by exposing them to modern sources of information on their doorstep. By design, the ICC was a community-based and community-managed institution where women could access information through online (e.g., internet, mobile phone etc.) and offline (e.g., CDs, TV etc.) resources. The ICC was managed by a group of local volunteer women who had the capacity and skills to use the devices and tools of modern ICTs. We noted an overwhelming participation and interest from local women in the activities of the ICC. The women wanted to receive information on a wide range of issues, from family planning, antenatal care, and childcare to garbage disposal and prevention of domestic violence. Overall, the ICC was successful in initiating a meaningful "information dialogue" at community level, where much-needed information was retrieved, negotiated, mediated, and disseminated through intimate and trusted relations. We conclude that ICTs have the capacity to cross the barriers of illiteracy and can reach out to disadvantaged women living under a conservative patriarchal regime.

Full Text Available Information literacy is a complex phenomenon that requires a multifaceted interdisciplinary approach as it is related to verbal communication, literacy, functional literacy and academic literacy, including issues of plagiarism. It also includes text authoring in a full range of genres, among others abstracts. Abstracting is a well-known act of verbal communication, and abstracts are a genre of written communication. The essence of abstracting is summarizing information making use of critical reading. Abstracting thus can be regarded as one of the instances of exercising information literacy on a higher level. Both information literacy and abstracting are of prime professional interest for linguists (among others in the field of ESP and information professionals.

Racial and Ethnic Differences in Tobacco Information Seeking and Information Sources: Findings From the 2015 Health Information National Trends Survey.

Nguyen, Anh B; Robinson, Joelle; O'Brien, Erin Keely; Zhao, Xiaoquan

2017-09-01

This article describes sources of health information, types of tobacco information sought, and trust in sources of tobacco information among U.S. racial/ethnic groups (Whites, Blacks, Hispanics, Asian and Pacific Islanders, and Other). Cross-sectional data (N = 3,788) from a nationally representative survey, HINTS-FDA 2015, were analyzed to examine unadjusted and adjusted associations between race/ethnicity and (a) first source of health information, (b) tobacco information seeking, and (c) trust in sources of tobacco information. Adjusted associations controlled for current tobacco product use and sociodemographic variables. Findings indicated that the Internet was the most common first source of health information while health care providers were the second most common source for all racial/ethnic groups. Tobacco-related health information seeking was more prevalent than other tobacco product information seeking. Unadjusted analyses indicated that a higher proportion of Whites sought other tobacco product information compared to Asians and Pacific Islanders. Trust was rated highest for doctors while trust for health organizations was rated second highest. Asians and Pacific Islanders had higher trust in the government compared to all other groups. Blacks had higher trust in religious organizations compared to all other groups besides Hispanics. Blacks had higher trust for tobacco companies compared to Whites and Other. Many of these differences were attenuated in adjusted analyses. This research has implications for tobacco control practice and policymaking by identifying potential dissemination strategies.

For a civilization of the post-industrial society which is defined as 'informational civilization,' the heightened interest to new technological expedients of any interaction with the information is characteristic. Now concept 'information' is defined as an independent category. The organization, storage, transmission and displaying of information, in essence, is one of the ways of its self- organization for a civilization of such type. Therefore branches bound with generating and support of information highways, are in the center of attention those who tries to capture strategic favorable positions in world community. The reasons of the geopolitical and economic strategy in this case are direct, 'easy-to-see' mechanisms of creation of the structures in investigation activity and industry, 'Easy-to- see,' analyzable, even predictable -- but not defining. The modern science knows the physical laws of composite system's self-organization, and, as clear now, the unclosed nonequilibrium system, which one is a World Net, is subject to the laws of such system's self-organization. Nowadays the fractal nature of all Webs' infrastructures as super complex self-organizing transport-information system is established. Besides, in a row of its performances we observe an openness, coherence, nonlinearly, that together with other aspects allows to identify it as physical fractal structure living on the laws of self-organization. The interest to this phenomenon is quite clear. We have to know the laws of behavior of a Web because it is one of the sides of appearance of Noosphere, and we must adequately interact with it. There are numerous important problems, bound with a Web, and attempts to resolve them are the first task of human community, as nevertheless the human person creates the Web (or nature by hand of the person?) It's very interesting to analyze the previous history of occurrence of such phenomenon, as a Web, and to do the attempts of the prognoses on the future. For

METHODS FOR ASSESSING SECURITY THREATS CONFIDENTIAL INFORMATION FOR THE INFORMATION AND TELECOMMUNICATIONS SYSTEMS

Full Text Available The article discusses the different approaches to assessing the safety of confidential information-term for information and telecommunication systems of various pre-appreciable destination in the presence of internal and external threats to its integrity and availability. The difficulty of ensuring the security of confidential information from exposure to information and telecommunication systems of external and internal threats at the present time, is of particular relevance. This problem is confirmed by the analysis of available statistical information on the impact of threats on the security circulating in the information and telecommunications system. Leak confidential information, intellectual property, information, know-how is the result of significant material and moral damage caused to the owner of the restricted information. The paper presents the structure of the indicators and criteria shows that the most promising are analytical criteria. However, their use to assess the level of security of confidential information is difficult due to the lack of appropriate mathematical models. The complexity of the problem is that existing traditional mathematical models are not always appropriate for the stated objectives. Therefore, it is necessary to develop mathematical models designed to assess the security of confidential information and its impact on information and telecommunication system threats.

Combining physics and philosophy, this is a uniquely interdisciplinary examination of quantum information science which provides an up-to-date examination of developments in this field. The authors provide coherent definitions and theories of information, taking clearly defined approaches to considering information in connection with quantum mechanics, probability, and correlations. Concepts addressed include entanglement of quantum states, the relation of quantum correlations to quantum information, and the meaning of the informational approach for the foundations of quantum mechanics. Furthermore, the mathematical concept of information in the communicational context, and the notion of pragmatic information are considered. Suitable as both a discussion of the conceptual and philosophical problems of this field and a comprehensive stand-alone introduction, this book will benefit both experienced and new researchers in quantum information and the philosophy of physics.

Informed choice requires information about both benefits and harms

women is seriously biased in favour of participation. Women are not informed about the major harms of screening, and the decision to attend has already been made for them by a public authority. This short-circuits informed decision-making and the legislation on informed consent, and violates...... the autonomy of the women. Screening invitations must present both benefits and harms in a balanced fashion, and should offer, not encourage, participation. It should be stated clearly that the choice not to participate is as sensible as the choice to do so. To allow this to happen, the responsibility...

Quality of Information

Christensen, Leif

Accounting and auditing is closely related to the quality of data. Two important elements supporting the quality of information are internal controls and materiality. Inspired by Simons (1994), these elements can be considered “basic building blocks”. Internal controls are perhaps the most...... important element, as they ensure that information used for management purposes has the required quality (Kinney, 2000). This information can be used as a basis for preparing the external financial reporting (COSO, 2013) and as a prerequisite for establishing information-based management control systems...... (MCS) (Simons, 1994). When regarding management controls as a package, internal controls are part of the administrative controls and often formalised in policies and procedures (Malmi and Brown, 2008). The level of controls should be guided by the need for reliable information. These considerations...

Information, Overconfidence and Trading: Do the Sources of Information Matter?

OpenAIRE

Margarida Abreu; Victor Mendes

2011-01-01

We investigate how the strength of the positive association between frequency of trading and information acquisition is dependent on investors’ self‐confidence and on the sources of information used by investors. Our results confirm that the more frequently individual investors invest in information, the more they trade in financial products. Our results also confirm previous findings that overconfident investors, who show a better than average bias, trade more frequently. In this paper, we a...

Information Asymmetry in Federations

Directory of Open Access Journals (Sweden)

Alexander Mikhailovich Libman

2014-12-01

Full Text Available The paper investigates the problems of information transmission between levels of government in a federal state. The central government in a federation typically faces serious difficulties while collecting information on economic and political situation in the regions. There are two types of problems: lack of incentives for the regions to accurately collect information and strategic manipulation of information, which are discussed in the paper along with possible solutions. In particular, overcoming information asymmetry would require the development of national parties or informal coalitions of bureaucrats and politicians of the center and of the regions, creating incentives for regional politicians to back the successful functioning of the federal level. Furthermore, the paper discusses the issue of «informal decentralization», which emerges as a result of information asymmetry, and its consequences for the functioning of a federal state, including both advantages and disadvantages. We conclude that under information asymmetry the organization of the federation will inevitably turn into an issue of permanent negotiations and bargaining between the center and the regions, which functions as the information acquisition tool for optimal allocation of authorities in a federation

During the tenth five-year plan, along with the digitization of information, and the development of information transmission network, the co-construction and sharing of China's nuclear industry information is facing a new development opportunities and challenges. This paper is based on the analysis of the nuclear library status and characteristics, combined of the development process of nuclear information resources over the past 20 years. For the characteristic of information sharing and services in the net environment, the problem in the current co-construction and sharing of nuclear information, and the needs of the future nuclear research and development of nuclear production, this paper forecast the work trends of nuclear information, and gives some countermeasure to strength the development of the co-construction and sharing of nuclear information.

Library Learning: Undergraduate Students’ Informal, Self-directed, and Information Sharing Strategies

Directory of Open Access Journals (Sweden)

Jo Ann Murphy

2014-04-01

Full Text Available A focus group study of fourteen University of Saskatchewan second to fourth year humanities and social science undergraduate students was conducted in the fall of 2011. The purpose of the research was to determine how students learn about library resources and services. Findings indicate that the participants often use a variety of informal, self-directed and information sharing strategies. Seeking help from professors, peers, friends, and family members is a common practice. Convenience, familiarity, and perceived knowledge are key factors that determine who and how these students learn about the library. Formal instruction and seeking assistance from librarians did not resonate for participants as a typical approach for learning about the library. The author suggests that undergraduate students engage in informal learning and information sharing as many ‘adult learners’ do, similar to an employment setting. The library, within the formal educational structure, lends itself to a more informal learning context. The study concludes that libraries must continue to develop resources, services, and innovative programs that support students’ informal learning styles, while also providing formal instruction as part of the undergraduate curriculum ensuring students are exposed early on to core foundational skills that contribute to their success as informal and self-directed learners.
