    2008-01-01

    SimDialog is a visual editor for dialog in computer games. This paper presents the design of SimDialog, illustrating how script writers and non-programmers can easily create dialog for video games with complex branching structures and dynamic response characteristics. The system creates dialog as a directed graph. This allows for play using the dialog with a state-based cause and effect system that controls selection of non-player character responses and can provide a basic scoring mechanism ...

    Full Text Available  The paper deals with one of the fast developing modern educational approaches – the pedagogy of dialog, based on the philosophical works and concepts of the well-known thinkers of the 20-th century: M. Buber, F. Ebner, O. Rosenshtok-Hussy, M. Bakhtin, etc. Two main directions of dialogic pedagogy are outlined – the instrumental and ontological. Within the framework of the first direction, the dialog is considered to be the main means or instrument of effective teaching used for communication skills development. According to the ontological version, the dialog is not only the instrument, but rather the dominating goal of education: it facilitates meaning- ful assimilation of skills and knowledge, including the learning ability; promotes cooperation and communal life skills; provides favorable conditions for versatile creative self-development. The supporters of this approach regard the real people, as well as the art works, nature, culture, alter ego etc, as the dialog subjects. The paper observes the main characteristics or prerequisites of dialogic interaction: dialogic attitude (emotionally ethical precondition; antinomian thinking (intellectual precondition; open outlook and creativity (precondition of personal meaning creation in the course of dialog. The comparative analysis of dialogism and non-dialogism of schoolchildren from Riga and Moscow are given regarding their behavior in conflicting situations; attitude to extremism; and reactions to bulling situations. The author is convinced that studying students’ dialogism in different age groups should be continued to improve the educational process effectiveness. Shearing the positive experience in dialogic education by Latvian and Russian colleagues can be very useful.

  6. Values in dialogic pedagogy

    2015-02-01

    Full Text Available In November 2014 on the Dialogic Pedagogy Journal Facebook page, there was an interesting discussion of the issue of values in dialogic pedagogy[1]. The main issue can be characterized as the following. Should dialogic pedagogy teach values? Should it avoid teaching values? Is there some kind of a third approach? The participants of the Facebook discussions were focusing on teaching values in dialogic pedagogy and not about teaching aboutvalues. On the one hand, it seems to be impossible to avoid teaching values. However, on the other hand, shaping students in some preset molding is apparently non-dialogic and uncritical (Matusov, 2009. In the former case, successful teaching is defined by how well and deeply the students accept and commit to the taught values. In the latter case, successful dialogic teaching may be defined by students’ critical examination of their own values against alternative values in a critical dialogue. Below, Eugene Matusov and Jay Lemke, active participants of this Facebook dialogue, provide their reflection on this important issue and encourage readers to join their reflective dialogue.[1] See in a public Facebook domain: https://www.facebook.com/DialogicPedagogyJournal/posts/894734337204533, https://www.facebook.com/DialogicPedagogyJournal/posts/896916850319615

    In Monitoring Adaptive Spoken Dialog Systems, authors Alexander Schmitt and Wolfgang Minker investigate statistical approaches that allow for recognition of negative dialog patterns in Spoken Dialog Systems (SDS). The presented stochastic methods allow a flexible, portable and  accurate use.  Beginning with the foundations of machine learning and pattern recognition, this monograph examines how frequently users show negative emotions in spoken dialog systems and develop novel approaches to speech-based emotion recognition using hybrid approach to model emotions. The authors make use of statistical methods based on acoustic, linguistic and contextual features to examine the relationship between the interaction flow and the occurrence of emotions using non-acted  recordings several thousand real users from commercial and non-commercial SDS. Additionally, the authors present novel statistical methods that spot problems within a dialog based on interaction patterns. The approaches enable future SDS to offer m...

  11. Mathematical investigation of one-way transform matrix options

    International Nuclear Information System (INIS)

    Cooper, James Arlin

    2006-01-01

    One-way transforms have been used in weapon systems processors since the mid- to late-1970s in order to help recognize insertion of correct pre-arm information while maintaining abnormal-environment safety. Level-One, Level-Two, and Level-Three transforms have been designed. The Level-One and Level-Two transforms have been implemented in weapon systems, and both of these transforms are equivalent to matrix multiplication applied to the inserted information. The Level-Two transform, utilizing a 6 x 6 matrix, provided the basis for the ''System 2'' interface definition for Unique-Signal digital communication between aircraft and attached weapons. The investigation described in this report was carried out to find out if there were other size matrices that would be equivalent to the 6 x 6 Level-Two matrix. One reason for the investigation was to find out whether or not other dimensions were possible, and if so, to derive implementation options. Another important reason was to more fully explore the potential for inadvertent inversion. The results were that additional implementation methods were discovered, but no inversion weaknesses were revealed

  13. THE DIALOGICAL SELF IN PSYCHOANALYSIS.

    Science.gov (United States)

    Muller, Felipe

    2016-10-01

    This paper describes the shift that appears to be taking place in contemporary psychoanalysis, as reflected among intersubjective approaches, from a monological conception of the self to a dialogical one. The monological self emphasizes the separation between mind, body, and external world, focusing on the representational and descriptive/referential function of language. In contrast, the dialogical self emphasizes practices, the permeable nature of relationships between subjects, and the constitutive function of language. This paper attempts to explain the growing emphasis on the dialogical self, understood from a theoretical, metatheoretical, and technical point of view, using contemporary intersubjective approaches to illustrate this shift. © 2016 The Psychoanalytic Quarterly, Inc.

  16. A proposal to manage multi-task dialogs in conversational interfaces

    Directory of Open Access Journals (Sweden)

    David GRIOL

    2016-11-01

    Full Text Available The emergence of smart devices and recent advances in spoken language technology are currently extending the use of conversational interfaces and spoken interaction to perform many tasks. The dialog management task of a conversational interface consists of selecting the next system response considering the user's actions, the dialog history, and the results of accessing the data repositories. In this paper we describe a dialog management technique adapted to multi-task conversational systems. In our proposal, specialized dialog models are used to deal with each specific subtask of dialog objective for which the dialog system has been designed. The practical application of the proposed technique to develop a dialog system acting as a customer support service shows that the use of these specialized dialog models increases the quality and number of successful interactions with the system in comparison with developing a single dialog model.

    Full Text Available It has almost passed one century from the emergence of the idea of the inter-religious dialog. The idea, being based on the assumption that no religion has the absolute truth, believes that there is the possibility of the dialog between all the existent religions in the social world. The dialog could make the coexistence and peace between the religions possible. The importance of this issue is increasingly growing and different ideas have been presented in the different religion departments worldwide. After the Iranian Islamic Revolution, a new image of Islam was offered to the world. An image whose true exposure made the use of the inter-religious dialog unavoidable. This also caused appearance of different views between the Muslim scholars. This article seeks to provide a presentation of three different approaches to the inter-religious dialog by exploring the works of three eminent scholars in the field; Mohaghegh Damad, Abolhassan Navab and Mohammad Masjed Jamei. These three approaches are:   · Inter-religious dialog as an interaction-oriented action    · Inter-religious dialog as a necessity-oriented action    · Inter-religious dialog as a backgroubd-oriented action    The necessity-oriented action is the approach taken by Mohaghegh Damad. He emphasizes on the acceptance of other religions. The active action referring to this acceptance is the foundation of this approach. This approach, accepting the developmental discourse in the meaning of inter-religious dialog, believes that this kind of dialog has been evolved from defensive and opposing to a new meaning. Hence, the inter-religious dialog in its new meaning possesses three conditions; the existence of common rights, emphasis on mutual respect and the effort for the two sides for religious exchange. This approach­ assumes that we must first establish a pattern from the current experiences of inter-religious dialogs in order to have an ideal cooperation and to fortify it. Then

  19. Estimating Spoken Dialog System Quality with User Models

    CERN Document Server

    Engelbrecht, Klaus-Peter

    2013-01-01

    Spoken dialog systems have the potential to offer highly intuitive user interfaces, as they allow systems to be controlled using natural language. However, the complexity inherent in natural language dialogs means that careful testing of the system must be carried out from the very beginning of the design process.   This book examines how user models can be used to support such early evaluations in two ways:  by running simulations of dialogs, and by estimating the quality judgments of users. First, a design environment supporting the creation of dialog flows, the simulation of dialogs, and the analysis of the simulated data is proposed.  How the quality of user simulations may be quantified with respect to their suitability for both formative and summative evaluation is then discussed. The remainder of the book is dedicated to the problem of predicting quality judgments of users based on interaction data. New modeling approaches are presented, which process the dialogs as sequences, and which allow knowl...

  20. Reinterpreting individualism and collectivism. Their religious roots and monologic versus dialogic person-other relationship.

    Sampson, E E

    2000-12-01

    Examining the religious roots of individualism and collectivism and seeing them as defining alternative conceptions of the person-other relationship reveal a close link between Christianity and the former and between rabbinic Judaism and the latter. Comparisons between these 2 religious formations in the Western world expose a relationship between Christian individualism and an instrumental and monologic understanding of the person-other relationship and a contrasting rabbinic view that offers a formative and dialogic understanding of that relationship. Because the Christian view has been dominant, its understandings have framed the debates on individualism-collectivism and defined the options available for the person-other relationship, providing a somewhat distorted picture of the possibilities for humankind. The dialogic and formative perspective of the rabbinic tradition introduces an alternative portrait of human nature.

    Belackova, Vendula; Shanahan, Marian; Ritter, Alison

    2017-05-30

    Objective The aim of the present study was to develop a framework for assessing regulatory options for medicinal cannabis in Australia. Methods International regulatory regimes for medicinal cannabis were reviewed with a qualitative policy analysis approach and key policy features were synthesised, leading to a conceptual framework that facilitates decision making across multiple dimensions. Results Two central organising dimensions of medicinal cannabis regulation were identified: cannabis supply and patient authorisation (including patient access). A number of the different supply options can be matched with a number of different patient authorisation options, leading to a matrix of possible regulatory regimes. Conclusions The regulatory options, as used internationally, involve different forms of cannabis (synthetic and plant-based pharmaceutical preparations or herbal cannabis) and the varying extent to which patient authorisation policies and procedures are stringently or more loosely defined. The optimal combination of supply and patient authorisation options in any jurisdiction that chooses to make medicinal cannabis accessible will depend on policy goals. What is known about the topic? Internationally, regulation of medicinal cannabis has developed idiosyncratically, depending on formulations that were made available and local context. There has been no attempt to date in the scientific literature to systematically document the variety of regulatory possibilities for medicinal cannabis. What does this paper add? This paper presents a new conceptual schema for considering options for the regulation of medicinal cannabis, across both supply and patient authorisation aspects. What are the implications for practitioners? The design of regulatory systems in Australia, whether for pharmaceutical or herbal products, is a vital issue for policy makers right now as federal and state and territory governments grapple with the complexities of medicinal cannabis

  6. Dialogism in Advertising Persuasion

    Directory of Open Access Journals (Sweden)

    Maria Helena Cruz Pistori

    2014-06-01

    Full Text Available This article analyzes two advertisements from the same brand, but produced in different local media: France and Brazil. It aims to pursue the interrelation and nexus needed between the verbal, visual and extraverbal dimensions to produce and understand the effects of persuasive sense. Concepts from ancient and modern Rhetoric, as well as dialogic discourse analysis notions and categories, inspired in the works of Bakhtin and the Circle, are the article’s theoretical-methodological basis. In the chosen advertisements, we observe the tense way they reflect and refract reality and how this is expressed in concrete utterances, constructed according to genre coercions. By analyzing the produced meaning effects, we especially highlight the presence of persuasion in different dialogic relationships allowed by the texts, audience importance in effect construction of text persuasive meaning, and proximity between advertisement and epidictic genre in ancient rhetoric. Persuasive dialogic relationships express broad and different spheres of human activity, in connection with the organization of social life, space and time; in fact, they are not aimed at product purchase, but at access to a way of life, which is linked to ideological values of privilege.

    Full Text Available This review hopes to present an alternative model to confessional religious education and the kind of role religion can have in teaching and education. It is framed by the conceptualization of education as simultaneously being and becoming (van Manen 1991, 67. This dichotomous description underlines the challenging tension of balancing present realities with future anticipations, a tension which is perhaps the defining feature of education. In theoretical terms this review draws on sociocultural and dialogic educational research, particularly Rupert Wegerif’s notion of “dialogic space” (Wegerif 2007, 4, and a “Global Education: World Religions” -course recently run as part of the Summer School for Human Sciences at the University of Jyväskylä. The review opens by introducing the pedagogic orientation for the course and a simple cultural model developed within the course. Following this, the guidelines for the development of “dialogic space” are introduced with possible implications for Religious Education concluding the paper.

  9. Bakhtin and Buber: Problems of Dialogic Imagination

    Directory of Open Access Journals (Sweden)

    Nina Perlina

    1984-09-01

    Full Text Available Recent publications of biographical materials on Mikhail Bakhtin demonstrate that he was familiar with the writings of Martin Buber. The philosophical and aesthetic verbal expression of Buber's ideas within the time-spatial universe of Bakhtin's own awareness allows us to discuss this obvious biographical evidence in a wider cultural context. The central opposition of Buber's and Bakhtin's systems is the dialogic dichotomous pair: "Ich und Du" (I and Thou, or "myself and another." Bakhtin's dialogic imagination is rooted in the binaries of the subject-object relations which he initially formulated as "responsibility" and "addressivity," that is to say, as individual awareness and its responsiveness of life. The basic words of Bakhtin's philosophical aesthetics can be understood as the "relation to the other," and their semantics and terminological meaning are directly related to Martin Buber (his work, Ich und Du , 1923. In the 1930s-60s Bakhtin developed the concepts of responsibility and addressivity into his universal dialogic theory of speech-genres. His hierarchy of speech-genres was built in order to establish relations between different sub-genres of the novel (various types of poetic utterances and different species of individual discourse. However, the entire edifice of this dialogic system remained unfinished, and several types of dialogic relations between individual pronouncements of the characters and individual novelistic genres were not discussed by him. Buber's ideas on the dialogue can be used as a clue to one possible interpretation of the function of authoritative and internally persuasive discourses in different sub-genres of the novel (the novel of confession, the Bildungsroman , the autobiographical novel. In this article, Buber's philosophical cycle is used as an aid in reconstructing the integral whole of Bakhtin's "dialogic imagination," as this dialogic mode of thinking goes through his unfinished works: "Author and

    Full Text Available The present paper aims to introduce the Nucleus of Investigation and Social and Educational Action (NIASE, which is an academic nucleus in Brazil whose practices are based on the concept of dialogic learning as well as on the communicative action theory by Jürgen Habermas and on the concept of dialogicity by Paulo Freire. Dialogic learning is the result of dialogue directed to the overcoming of social and educational challenges which can be achieved through seven articulated principles: egalitarian dialogue, cultural intelligence, transformation, instrumental dimension, creation of meaning, sympathy and equality of differences. NIASE, which was founded in Brazil in 2002 with the purpose of working with education, research and extension, has found in dialogic learning the support for the democratic organization of schooling and on schooling educational environments, whose participants decide on seeking learning qualification and the social respect from the involved groups. As a result of such actions, the concept of dialogic learning has made an impact on education and academic production in Brazil, therefore contributing to consolidate the social commitment and the dialogue between the scientific community and the broader context in which it is involved.

  11. A Network Model of Interpersonal Alignment in Dialog

    Directory of Open Access Journals (Sweden)

    Alexander Mehler

    2010-06-01

    Full Text Available In dyadic communication, both interlocutors adapt to each other linguistically, that is, they align interpersonally. In this article, we develop a framework for modeling interpersonal alignment in terms of the structural similarity of the interlocutors’ dialog lexica. This is done by means of so-called two-layer time-aligned network series, that is, a time-adjusted graph model. The graph model is partitioned into two layers, so that the interlocutors’ lexica are captured as subgraphs of an encompassing dialog graph. Each constituent network of the series is updated utterance-wise. Thus, both the inherent bipartition of dyadic conversations and their gradual development are modeled. The notion of alignment is then operationalized within a quantitative model of structure formation based on the mutual information of the subgraphs that represent the interlocutor’s dialog lexica. By adapting and further developing several models of complex network theory, we show that dialog lexica evolve as a novel class of graphs that have not been considered before in the area of complex (linguistic networks. Additionally, we show that our framework allows for classifying dialogs according to their alignment status. To the best of our knowledge, this is the first approach to measuring alignment in communication that explores the similarities of graph-like cognitive representations.

  12. Priorities of Dialogic Speech Teaching Methodology at Higher Non-Linguistic School

    Directory of Open Access Journals (Sweden)

    Vida Asanavičienė

    2011-04-01

    Full Text Available The article deals with a number of relevant methodological issues. First of all, the author analyses psychological peculiarities of dialogic speech and states that the dialogue is the product of at least two persons. Therefore, in this view, dialogic speech, unlike monologic speech, happens impromptu and is not prepared in advance. Dialogic speech is mainly of situational character. The linguistic nature of dialogic speech, in the author’s opinion, lies in the process of exchanging replications, which are coherent in structural and functional character. The author classifies dialogue groups by the number of replications and communicative parameters. The basic goal of dialogic speech teaching is developing the abilities and skills which enable to exchange replications. The author distinguishes two basic stages of dialogic speech teaching: 1. Training of abilities to exchange replications during communicative exercises. 2. Development of skills by training the capability to perform exercises of creative nature during a group dialogue, conversation or debate.

    Mariani, Beatriz Zaki Porcelli; Guarinello, Ana Cristina; Massi, Giselle; Tonocchi, Rita; Berberian, Ana Paula

    this study aims to discuss the use of Brazilian sign language as the first language for a deaf individual going to a bilingual dialogic clinic from dialogic activities. This is a longitudinal study, including one deaf individual, called N, interacting with his family and speech therapists. During the therapeutic process developed inside the bilingual dialogical clinic, N participated in interactive contexts and could constitute himself as author of his sign language texts. In addition, he started to act dialogically and use verbal and nonverbal signs. Through interactive and dialogical situations developed inside the speech language therapy clinic, this deaf participant got control of his sign language, and started to get interest in and control of the Portuguese language, especially in the written form.

    Clinical data access involves complex but opaque communication between medical researchers and query analysts. Understanding such communication is indispensable for designing intelligent human-machine dialog systems that automate query formulation. This study investigates email communication and proposes a novel scheme for classifying dialog acts in clinical research query mediation. We analyzed 315 email messages exchanged in the communication for 20 data requests obtained from three institutions. The messages were segmented into 1333 utterance units. Through a rigorous process, we developed a classification scheme and applied it for dialog act annotation of the extracted utterances. Evaluation results with high inter-annotator agreement demonstrate the reliability of this scheme. This dataset is used to contribute preliminary understanding of dialog acts distribution and conversation flow in this dialog space. Copyright © 2015 Elsevier Inc. All rights reserved.

    2018-05-01

    Full Text Available In recent times, with the increasing interest in conversational agents for smart homes, task-oriented dialog systems are being actively researched. However, most of these studies are focused on the individual modules of such a system, and there is an evident lack of research on a dialog framework that can integrate and manage the entire dialog system. Therefore, in this study, we propose a framework that enables the user to effectively develop an intelligent dialog system. The proposed framework ontologically expresses the knowledge required for the task-oriented dialog system’s process and can build a dialog system by editing the dialog knowledge. In addition, the framework provides a module router that can indirectly run externally developed modules. Further, it enables a more intelligent conversation by providing a hierarchical argument structure (HAS to manage the various argument representations included in natural language sentences. To verify the practicality of the framework, an experiment was conducted in which developers without any previous experience in developing a dialog system developed task-oriented dialog systems using the proposed framework. The experimental results show that even beginner dialog system developers can develop a high-level task-oriented dialog system.

    2016-05-01

    Full Text Available In this paper, we assess the applicability of user simulation techniques to generate dialogs which are similar to real human-machine spoken interactions.To do so, we present the results of the comparison between three corpora acquired by means of different techniques. The first corpus was acquired with real users.A statistical user simulation technique has been applied to the same task to acquire the second corpus. In this technique, the next user answer is selected by means of a classification process that takes into account the previous dialog history, the lexical information in the clause, and the subtask of the dialog to which it contributes. Finally, a dialog simulation technique has been developed for the acquisition of the third corpus. This technique uses a random selection of the user and system turns, defining stop conditions for automatically deciding if the simulated dialog is successful or not. We use several evaluation measures proposed in previous research to compare between our three acquired corpora, and then discuss the similarities and differences with regard to these measures.

    Full Text Available This study introduces a system design in a form of cognitive dialog game (DiaCog to support pedagogical factors and student learning model ideas. The purpose of the study is to describe how such a design achieves tracking and adapting students’ knowledge and mastery learning levels as a cognitive assistant. Also, this study shows alternative ways for supporting intelligent personal learning, tutoring systems, and MOOCS. This paper explains method called DiaCog that uses structure for students` thinking in an online dialog by tracking student`s level of learning/knowledge status. The methodology of computing is the semantic that match between students` interactions in a dialog. By this way it informs DiaCog’s learner model to inform the pedagogical model. Semantic fingerprint matching method of DiaCog allows making comparisons with expert knowledge to detect students` mastery levels in learning. The paper concludes with the DiaCog tool and methodologies that used for intelligent cognitive assistant design to implement pedagogical and learner model to track and adapt students’ learning. Finally, this paper discusses future improvements and planned experimental set up to advance the techniques introduced in DiaCog design.

    Augmented reality, augmented television and second screen are cutting edge technologies that provide end users extra and enhanced information related to certain events in real time. This enriched information helps users better understand such events, at the same time providing a more satisfactory experience. In the present paper, we apply this main idea to human–robot interaction (HRI), to how users and robots interchange information. The ultimate goal of this paper is to improve the quality of HRI, developing a new dialog manager system that incorporates enriched information from the semantic web. This work presents the augmented robotic dialog system (ARDS), which uses natural language understanding mechanisms to provide two features: (i) a non-grammar multimodal input (verbal and/or written) text; and (ii) a contextualization of the information conveyed in the interaction. This contextualization is achieved by information enrichment techniques that link the extracted information from the dialog with extra information about the world available in semantic knowledge bases. This enriched or contextualized information (information enrichment, semantic enhancement or contextualized information are used interchangeably in the rest of this paper) offers many possibilities in terms of HRI. For instance, it can enhance the robot's pro-activeness during a human–robot dialog (the enriched information can be used to propose new topics during the dialog, while ensuring a coherent interaction). Another possibility is to display additional multimedia content related to the enriched information on a visual device. This paper describes the ARDS and shows a proof of concept of its applications.

The seven principles of dialogic learningare discussed, along with other reproductionist theories and practices from the educationalfield, demonstrating how the former both surpass the latter. The article also reflectsopen dialogue with the critical theories of education which the dialogic learningtheory is based on. These basic theories are, on the one hand, by authors who are distantin time but very close in their educational approach, such as Ferrer i Guàrdia, Vygotsky,or Paulo Freire, and, on the other hand, by other contemporary authors in critical pedagogy.Each of the seven principles presented are provided along with a critical examinationof a specific educational practice. The consequences of the implementation of dialogiclearning are underlined here through an analysis of innovative and critical educationalprojects which are academically successful.

  18. INNER DIALOGICITY OF MEDICAL SCIENTIFIC TEXTS

    Directory of Open Access Journals (Sweden)

    Efremova Nataliya Vladimirovna

    2015-06-01

    Full Text Available The author studies inner dialogicity as an integral property of a scientist's thinking activity, a way of a scientific idea development, one of the cognitive and discursive mechanisms of new knowledge formation, its crystallization and dementalisation in a text, as a way of search for truth. Such approach to dialogicity in the study of a scientific text makes it possible to analyze the cogitative processes proceeding in human consciousness and cognitive activity, allows to fully understand the stated scientific concept, to define pragmatic strategies of the author, to plunge into his reflexive world. On the material of medical scientific texts of N.M. Amosov and F. G. Uglov, famous scientists in the field of cardio surgery, it is established that traces of internal dialogicity manifestation in the textual space of scientists actualize the origin of new knowledge, the change of author's semantic positions, his ability to reflect, compare, analyze his own thoughts and actions, to estimate oneself and the features of thinking process which are realized in logic of a statement of the scientific concept, an explanation of concepts, terms at judgment of the points of view of contemporaries and predecessors, adherents and scientist's opponents, and also orientation to the addressee's presupposition, activization of his cogitative activity. Linguistic, discursive, verbal analysis singles out the impact on the addressee, his mental activity.

  3. An optioneering and concept design study for the Astrid sodium-gas heat exchanger matrix

    International Nuclear Information System (INIS)

    Hattrell, T.; Lopez-Ramirez, S.; Pilatis, N.

    2014-01-01

    The ASTRID generation IV sodium cooled fast reactor design being developed by the CEA requires a component to transfer heat from the core to the power cycle. One of the ASTRID configurations currently being developed by the CEA uses a sodium to gas heat exchanger (SGHE) to fulfil this function. The design of the SGHE is challenging because of the high temperature of the sodium coolant and the significant pressure differential between the sodium and gas sides of the heat exchanger. This paper presents a study of the options examined for the ASTRID SGHE. A compact, superplastic formed diffusion bonded (SPF-DB) heat exchanger matrix (e.g. SGHE core) is proposed, based on the aerospace technology used by Rolls-Royce to manufacture light and strong wide chord fan blades for gas turbines. The in-house code CHESS is used to examine a number of feasible configurations for the matrix of the heat exchanger component and an optimisation study to maximise the thermal and mechanical performance of the most promising configurations is reported. The optimal matrix geometry identified by the study has a power density for the heat transfer region 157%1 greater than the baseline geometry (authors)

    We present a custom integrated circuit, named DIALOG, which is a fundamental building block in the front-end architecture of the LHCb Muon detector. DIALOG is realized in IBM 0.25 um technology, using radiation hardening layout techniques. DIALOG integrates important tools for detector time alignment procedures and time alignment monitoring on the front- end system. In particular, it integrates 16 programmable delays, which can be regulated in steps of 1 ns. Many other features, necessary for the Muon trigger operation and for a safe front-end monitoring are integrated: DIALOG generates the information used by the trigger as a combination of its 16 inputs from the Amplifier-Shaper-Discriminator (ASD) chips, it generates the thresholds of the ASD, it monitors the rate of all its input channels. We describe the circuit architecture, its internal blocks and its main modes of operation.

    Full Text Available Political campaign on 2004 was marked by monologue campaigns in the form of mass rally and mass gathering. Information dissemination for the mass was carried out by placing signpost, banners, and pamphlets depicting party’s symbol.  This kind of campaign belonged to one way communication. Both political party and political leaders were failed to gain feedback from the mass, whereas feedback reflected public’s needs and wishes.  As consequences, monologue campaigns provide us with low quality campaign oriented toward figures, not their programs.  Considering this, a dialogues form of campaign is offered for repairing ineffective political communication between party and people. Dialogical campaigns establish a two-way-communication between party and public, provide ways to clearly communicate problems surrounding the whole situation packaged with party’s point of view and its solutions. By conducting dialogical campaign which reflected a-two-way- communication, campaigners and policymakers would benefit from the exchange of public aspirations along the process.

  9. Reorganization of personal identity in the context of motivational dynamics and internal dialogical activity.

    Science.gov (United States)

    Batory, Anna

    2014-08-01

    Identity is constantly constructed and reconstructed. It may be assumed that there are six fundamental motivational goals according to which it is organized: self-esteem, self-efficacy, continuity, distinctiveness, belonging, and meaning (Vignoles, 2011). Moreover, identity is shaped by its dialogical nature (Hermans, 2003; van Halen & Janssen, 2004). The longitudinal study was conducted to examine both the motivational and the dialogical basis of identity structure dynamics. The results showed that the more the identity element was connected with a sense of continuity and the more dialogical it was, the greater the perceived centrality of this element was after two months. Furthermore, the more the identity element satisfied the self-esteem and belonging motives, the more positive was the affect ascribed to it. In the behavioral domain of identity, participants more strongly manifested those identity aspects that were earlier rated as more dialogical and satisfying the motive of belonging. The results showed that the motivational underpinnings of identity along with its dialogical nature explain changes in identity structure. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  10. Learning Task Knowledge from Dialog and Web Access

    Directory of Open Access Journals (Sweden)

    Vittorio Perera

    2015-06-01

    Full Text Available We present KnoWDiaL, an approach for Learning and using task-relevant Knowledge from human-robot Dialog and access to the Web. KnoWDiaL assumes that there is an autonomous agent that performs tasks, as requested by humans through speech. The agent needs to “understand” the request, (i.e., to fully ground the task until it can proceed to plan for and execute it. KnoWDiaL contributes such understanding by using and updating a Knowledge Base, by dialoguing with the user, and by accessing the web. We believe that KnoWDiaL, as we present it, can be applied to general autonomous agents. However, we focus on our work with our autonomous collaborative robot, CoBot, which executes service tasks in a building, moving around and transporting objects between locations. Hence, the knowledge acquired and accessed consists of groundings of language to robot actions, and building locations, persons, and objects. KnoWDiaL handles the interpretation of voice commands, is robust regarding speech recognition errors, and is able to learn commands involving referring expressions in an open domain, (i.e., without requiring a lexicon. We present in detail the multiple components of KnoWDiaL, namely a frame-semantic parser, a probabilistic grounding model, a web-based predicate evaluator, a dialog manager, and the weighted predicate-based Knowledge Base. We illustrate the knowledge access and updates from the dialog and Web access, through detailed and complete examples. We further evaluate the correctness of the predicate instances learned into the Knowledge Base, and show the increase in dialog efficiency as a function of the number of interactions. We have extensively and successfully used KnoWDiaL in CoBot dialoguing and accessing the Web, and extract a few corresponding example sequences from captured videos.

    Dialogic pedagogy is being promoted in science teacher education but the literature on dialogic pedagogy tends to focus on explicit voices, and so runs the risk of overlooking the important role that material objects often play in science education. In this paper we use the findings of a teacher survey and classroom case study to argue that there…

    This article explores the relationship between ontological assumptions and studies of educational dialogue through a focus on Bakhtin's "dialogic". The term dialogic is frequently appropriated to a modernist framework of assumptions, in particular the neo-Vygotskian or sociocultural tradition. However, Vygotsky's theory of education is dialectic,…

    2004-11-14

    A total of 447 dissertation abstracts were received for the DIALOG V Program, with 146 individuals applying for the DIALOG V Symposium; 47 were invited and 45 have accepted. This represents a significant increase compared to the DIALOG IV Program in which 221 abstracts were registered and 124 applied for the symposium. The importance of the dissertation registration service is indicated by the increasing number of individuals who take time to register their dissertation even when they are not interested in applying to the symposium. The number of visits to the webpage has also increased significantly over the years. This also reflects graduate interest in being part of the on-line Dissertation Registry and receiving the weekly electronic DIALOG Newsletter. See http://aslo.org/phd.html for details. The DIALOG symposium reaches approximately 40 new PI's at a pivotal point in their research careers. Based on their comments, the symposium changes the way participants think, communicate, and approach their research. The science community and the general population will benefit from the perspectives these new PI's bring back to their home institutions and share with their students and colleagues. This group should act as a catalyst to move the entire field in exciting new, interdisciplinary directions. To reach more graduates, plans are underway to establish the symposium on an annual basis. By facilitating the development of close collegial ties, symposium participants come away with a network of colleagues from around the globe with interests in aquatic science research and education. Past participants are collaborating on research proposals, and all have noted that participation has enabled them to develop a more interdisciplinary view of their field, influencing the way they interpret, communicate, and approacli their research. The dissertation registry provides a unique introduction to the work of this most recent generation of aquatic scientists. Each

    We present a novel training framework for neural sequence models, particularly for grounded dialog generation. The standard training paradigm for these models is maximum likelihood estimation (MLE), or minimizing the cross-entropy of the human responses. Across a variety of domains, a recurring problem with MLE trained generative neural dialog models (G) is that they tend to produce 'safe' and generic responses ("I don't know", "I can't tell"). In contrast, discriminative dialog models (D) th...

    In this trial, we compared the relative efficacy of dialogical exposure group treatment using Gestalt empty-chair method with a supportive group in the treatment of symptoms stemming from traumatic loss in a post-war society. One-hundred and nineteen women whose husbands were either killed or registered as missing during the war in Bosnia and Herzegovina were quasi-randomized to seven sessions of group treatment with dialogical exposure or to an active control condition. Both interventions resulted in significant improvement from baseline to post-treatment for both kinds of loss, in terms of post-traumatic symptoms, general mental health and grief reactions, with the exception of depression and traumatic grief in the control condition. Regarding mean effect sizes (Cohen's d), pre-treatment to post-treatment improvements were moderate (d = 0.56) for the dialogical exposure group and small (d = 0.34) for the supportive group. Treatment gains were maintained at least until the 1-year follow-up. In controlled comparisons, dialogical exposure was superior concerning traumatic grief (Cohen's d = 0.37) and post-traumatic avoidance (d = 0.73) at post-treatment. Results show that short-term dialogical exposure group treatment was moderately effective in treating traumatically bereaved women. Research attests to high levels of symptoms among post-war civil populations, in particular, when a loved one was killed, which can lead not only to trauma reactions but also to severe separation distress. Grieving the loss of a loved one is hampered if the death remains unconfirmed. Unconfirmed loss could be conceptualized as unfinished business in terms of Gestalt therapy, which offers empty-chair dialogue for resolving unfinished business and grief. Dialogical exposure therapy (DET) supports the client in gaining awareness of and expressing his or her inner dialogues concerning the traumatic event, using Gestalt empty-chair method. Short-term DET was effective in

  1. Producing or reproducing reasoning? Socratic dialog is very effective, but only for a few.

    Goldin, Andrea Paula; Pedroncini, Olivia; Sigman, Mariano

    2017-01-01

    Successful communication between a teacher and a student is at the core of pedagogy. A well known example of a pedagogical dialog is 'Meno', a socratic lesson of geometry in which a student learns (or 'discovers') how to double the area of a given square 'in essence, a demonstration of Pythagoras' theorem. In previous studies we found that after engaging in the dialog participants can be divided in two kinds: those who can only apply a rule to solve the problem presented in the dialog and those who can go beyond and generalize that knowledge to solve any square problems. Here we study the effectiveness of this socratic dialog in an experimental and a control high-school classrooms, and we explore the boundaries of what is learnt by testing subjects with a set of 9 problems of varying degrees of difficulty. We found that half of the adolescents did not learn anything from the dialog. The other half not only learned to solve the problem, but could abstract something more: the geometric notion that the diagonal can be used to solve diverse area problems. Conceptual knowledge is critical for achievement in geometry, and it is not clear whether geometric concepts emerge spontaneously on the basis of universal experience with space, or reflect intrinsic properties of the human mind. We show that, for half of the learners, an exampled-based Socratic dialog in lecture form can give rise to formal geometric knowledge that can be applied to new, different problems.

    Full Text Available This article aims to provide an overview of the online interaction of the ‘Debating Europe’ platform using the theoretical framework of dialogic communication. A brief historical approach of the notion “Web 2.0” further informs about the functions of the ‘Debating Europe’ platform and its mission statement. Related work opens an interrogation on the ‘Debating Europe’ platform as a virtual space meant to connect European citizens and politicians in online debates concerning EU matters. The empirical study regards the use of dialogic principles on the ‘Debating Europe’ platform, focusing on a cross comparison of its three Internet channels: the website, the Facebook page and the Twitter account. The results indicate the website as the main dialogic channel, while Facebook and Twitter fulfill mainly information dissemination purposes.

    2015-01-01

    How to succeed in facilitating for empowering processes within social work practice is a central topic in both theoretical discussions and regarding its principles in practice. With a particular focus on how dialogical communication can play a part in order to practice empowering social work, through this text the author frames HUSK as a project facilitating the underpinning humanistic approaches in social work. Dialogical communication and its philosophical base is presented and recognized as a means to achieve empowering social work as well as highlighting the importance of the humanistic approach. The author also underscores how HUSK projects in themselves were enabled because of the required collaboration between service users, professionals, and researchers that signified HUSK. This is pinpointed as having potential for a future research agenda as well as pointing at how the outcomes of the projects may impact future social work practice when the goal is to conduct empowering social work.

  9. Dialogic Consensus In Clinical Decision-Making.

    Science.gov (United States)

    Walker, Paul; Lovat, Terry

    2016-12-01

    This paper is predicated on the understanding that clinical encounters between clinicians and patients should be seen primarily as inter-relations among persons and, as such, are necessarily moral encounters. It aims to relocate the discussion to be had in challenging medical decision-making situations, including, for example, as the end of life comes into view, onto a more robust moral philosophical footing than is currently commonplace. In our contemporary era, those making moral decisions must be cognizant of the existence of perspectives other than their own, and be attuned to the demands of inter-subjectivity. Applicable to clinical practice, we propose and justify a Habermasian approach as one useful means of achieving what can be described as dialogic consensus. The Habermasian approach builds around, first, his discourse theory of morality as universalizable to all and, second, communicative action as a cooperative search for truth. It is a concrete way to ground the discourse which must be held in complex medical decision-making situations, in its actual reality. Considerations about the theoretical underpinnings of the application of dialogic consensus to clinical practice, and potential difficulties, are explored.

    Directory of Open Access Journals (Sweden)

    Elie Cheniaux

    2014-12-01

    Full Text Available Objective: To briefly review how the main monist and dualist currents of philosophy of mind approach the mind-body problem and to describe their association with arguments for and against a closer dialog between psychoanalysis and neuroscience.Methods: The literature was reviewed for studies in the fields of psychology, psychoanalysis, neuroscience, and philosophy of mind.Results: Some currents are incompatible with a closer dialog between psychoanalysis and neurosciences: interactionism and psychophysical parallelism, because they do not account for current knowledge about the brain; epiphenomenalism, which claims that the mind is a mere byproduct of the brain; and analytical behaviorism, eliminative materialism, reductive materialism and functionalism, because they ignore subjective experiences. In contrast, emergentism claims that mental states are dependent on brain states, but have properties that go beyond the field of neurobiology.Conclusions: Only emergentism is compatible with a closer dialog between psychoanalysis and neuroscience.

    2014-02-01

    Full Text Available This email dialogue that we record and report here between Eugene Matusov and Rupert Wegerif, exemplifies Internet mediated dialogic education. When Eugene emailed Rupert with his initial (misunderstanding of Rupert's position about dialogic pedagogy Rupert felt really motivated to reply. Rupert was not simply motivated to refute Eugene and assert his correctness, although Rupert is sure such elements enter into every dialogue, but also to explore and to try to resolve the issues ignited by the talk in New Zealand. Through this extended dialogue Rupert's and Eugene's positions become more nuanced and focussed. Rupert brings out his concern with the long-term and collective nature of some dialogues claiming that the – "dialogue of humanity that education serves is bigger than the interests of particular students and particular teachers.…" – and so he argues that it is often reasonable to induct students into the dialogue so far so that they can participate fully. On the other hand, Eugene's view of dialogue seems more focussed on personal responsibility, particular individual desires, interests and positions, individual agency and answering the final ethical "damned questions" without an alibi-in-being.  Rupert claims that dialogic education is education FOR dialogue and Eugene claims that dialogic education is education AS dialogue. Both believe in education THROUGH dialogue but education through dialogue is not in itself dialogic education. For Rupert dialogic education can include ‘scaffolding’ for full participation in dialogue as long as dialogue is the aim. For Eugene dialogic education has to be a genuine dialogue and this means that a curriculum goal cannot be specified in advance because learning in a dialogue is always emergent and unpredictable. Our dialogue-disagreement is a relational and discursive experiment to develop a new genre of academic critical dialogue. The dialogue itself called to us and motivated us and flowed

    Historically the low and moderate income (LMI) market has been underserved by solar photovoltaics (PV), in part due to the unique barriers LMI residents face to participation in the PV market. The intent of this report is to identify the most promising strategies state policymakers might consider to finance PV for LMI customers across three housing types: single family, multi-family, and manufactured housing. The result is a financing matrix that documents the first and second tier financing options states may consider for each housing type. The first tier options were selected based upon their potential impact on LMI PV deployment. Second tier financing approaches could also be used to achieve state policy goals, but may not have as much effect on the relevant LMI market segment. Nevertheless, each financing option comes with tradeoffs that state policymakers may wish to consider when they make decisions about which financing approaches are best suited to achieve their LMI PV deployment goals.

  18. Dialogical argumentation in elementary science classrooms

    Science.gov (United States)

    Kim, Mijung; Roth, Wolff-Michael

    2018-02-01

    To understand students' argumentation abilities, there have been practices that focus on counting and analyzing argumentation schemes such as claim, evidence, warrant, backing, and rebuttal. This analytic approach does not address the dynamics of epistemic criteria of children's reasoning and decision-making in dialogical situations. The common approach also does not address the practice of argumentation in lower elementary grades (K-3) because these children do not master the structure of argumentation and, therefore, are considered not ready for processing argumentative discourse. There is thus little research focusing on lower elementary school students' argumentation in school science. This study, drawing on the societal-historical approach by L. S. Vygotsky, explored children's argumentation as social relations by investigating the genesis of evidence-related practices (especially burden of proof) in second- and third-grade children. The findings show (a) students' capacity for connecting claim and evidence/responding to the burden of proof and critical move varies and (b) that teachers play a significant role to emphasize the importance of evidence but experience difficulties removing children's favored ideas during the turn taking of argumentative dialogue. The findings on the nature of dialogical reasoning and teacher's role provide further insights about discussions on pedagogical approaches to children's reasoning and argumentation.

    Ibnu Mujib Mujib

    2013-12-01

    Full Text Available This paper highlights the perspective of dialog in the negotiation of Aceh identity. If observed, the context of the tsunami followed by the development of Aceh is not without impact at all on the Acehnese entity, but in fact it has triggered a strong clash especially between local identities and influences of global construction. Among the important things offered in this paper is an attempt to reproduce and create “public space” as a productive social capital, that is, a space that is expected to build an atmosphere of openness, egalitarianism, inclusivism of many diverse groups. Therefore, in responding to the wider variety of cultural plurality which penetrates through ethnic clusters, religions, political parties, and all forms of interests, it can be managed through the deliberations of dialog. Therefore, the “public space” that can serve to discuss, hold dialog, and even negotiate the clash of the Acehnese identity forms the modus operandi of the discussion of this article, especially in the context of the development of Aceh that is currently taking place. Keywords: Islam, locality, globality, public space, dialog, negotiation of identity, diversity of Islamic groups, the other.

    Full Text Available The study aimed to explore the dialog and knowledge of sexuality expressed by fathers or mothers of adolescents. A qualitative methodology with narrative design was used, with focus groups used for data collection. The results de-monstrate that the parents or mothers learn about sexuality from their own experiences, so this aspect is present in communication with their children. The most discussed topic was pregnancy, excluding sexually transmitted infections (STI, pornography and sexual diversity. The study concludes that dialogs with these participants about sexuality contain multiples discourses; intervention strategies oriented to promoting training spaces and communication skills regarding sexuality are required.

  8. Parent-specific reciprocity from infancy to adolescence shapes children's social competence and dialogical skills.

    Feldman, Ruth; Bamberger, Esther; Kanat-Maymon, Yaniv

    2013-01-01

    Reciprocity - the capacity to engage in social exchange that integrates inputs from multiple partners into a unified social event - is a cornerstone of adaptive social life that is learned within dyad-specific attachments during an early period of neuroplasticity. Yet, very little research traced the expression of children's reciprocity with their mother and father in relation to long-term outcomes. Guided by evolutionary models, we followed mothers, fathers, and their firstborn child longitudinally and observed mother-child and father-child reciprocity in infancy, preschool, and adolescence. In preschool, children's social competence, aggression, and prosocial behavior were observed at kindergarten. In adolescence, children's dialogical skills were assessed during positive and conflict interactions with same-sex best friends. Father-child and mother-child reciprocity were individually stable, inter-related at each stage, and consisted of distinct behavioral components. Structural equation modeling indicated that early maternal and paternal reciprocity were each uniquely predictive of social competence and lower aggression in preschool, which, in turn, shaped dialogical skills in adolescence. Father-adolescent reciprocity contributed to the dialogical negotiation of conflict, whereas mother-adolescent reciprocity predicted adolescents' dialogical skills during positive exchanges. Results highlight the role of parent-child reciprocity in shaping children's social collaboration and intimate relationships with non-kin members of their social world.

This is a qualitative study based on the dialogic-Kishu Kimkelay Ta Che research approach, with a design of two case studies derived from documentary sources. The procedure to collect and construct knowledge is the interpretation of the dialogic speech; as a data analysis, it focuses on pedagogical definitions from the perspective of transformative, excluding and conservative dimensions, in order to compare-interpret and reflect on educational inputs in relation to reading in a course of language and communication. As a result, it is observed the incongruity from the State in communicative curriculum design and its operational proposal, and in the regionalized construction the dialogic pedagogy “Enlazando Mundos” (Bridging Worlds is carrying out.

  11. Religion as dialogical resource: a socio-cultural approach.

    2013-06-01

    William James proposed a psychological study of religion examining people's religious experiences, and to see in what sense these were good for them. The recent developments of psychology of religion moved far from that initial proposition. In this paper, we propose a sociocultural perspective to religion that renews with that initial stance. After recalling Vygtotsky's core ideas, we suggest that religion, as cultural and symbolic system, participates to the orchestration of human activities and sense-making. Such orchestration works both from within the person, through internalized values and ideas, and from without, through the person's interactions with others, discourses, cultural objects etc. This leads us to consider religions as supporting various forms of dialogical dynamics-intra-psychological dialogues, interpersonal with present, absent or imaginary others, as well as inter-group dialogues-which we illustrate with empirical vignettes. The example of religious tensions in the Balkans in the 90's highlights how much the historical-cultural embeddedness of these dynamics can also lead to the end of dialogicality, and therefore, sense-making.

  12. "Socratic Circles are a Luxury": Exploring the Conceptualization of a Dialogic Tool in Three Science Classrooms

    Copelin, Michelle Renee

    Research has shown that dialogic instruction promotes learning in students. Secondary science has traditionally been taught from an authoritative stance, reinforced in recent years by testing policies requiring coverage. Socratic Circles are a framework for student-led dialogic discourse, which have been successfully used in English language arts and social studies classrooms. The purpose of this research was to explore the implementation process of Socratic Circles in secondary science classes where they have been perceived to be more difficult. Focusing on two physical science classes and one chemistry class, this study described the nature and characteristics of Socratic Circles, teachers' dispositions toward dialogic instruction, the nature and characteristics of student discussion, and student motivation. Socratic Circles were found to be a dialogic support that influenced classroom climate, social skills, content connections, and student participation. Teachers experienced conflict between using traditional test driven scripted teaching, and exploring innovation through dialogic instruction. Students experienced opportunities for peer interaction, participation, and deeper discussions in a framework designed to improve dialogic skills. Students in two of the classrooms showed evidence of motivation for engaging in peer-led discussion, and students in one class did not. The class that did not show evidence of motivation had not been given the same scaffolding as the other two classes. Two physical science teachers and one chemistry teacher found that Socratic Circles required more scaffolding than was indicated by their peers in other disciplines such as English and social studies. The teachers felt that student's general lack of background knowledge for any given topic in physical science or chemistry necessitated the building of a knowledge platform before work on a discussion could begin. All three of the teachers indicated that Socratic Circles were a

    2017-09-01

    Full Text Available Introduction: a distinctive feature of modern psychological knowledge is an extreme degree of disintegration manifested in an infinite array of publications describing local fragments of the studied reality outside the context of integrity. Simultaneously, development of knowledge without its metatheoretical interpretation gives it a sporadic character and, consequently, restricts the optimal solutions. The author’s attempt to solve this urgent problem is presented in the framework of sociocultural-interdeterminist dialogical metatheory of integration of psychological knowledge. Methodological foundations with substantial characterisation of metatheory are described. A research objective is to present innovative and heuristic potential of the meta-approach demonstration illustrated through the teacher’s psychological anti-deforming model. Materials and Methods: the methodological basis of research is presented by the sociocultural interdeterminist dialogical approach to education phenomenology analysis which innovative potential is illustrated by the example of teacher’s personality deformation. System analysis, comparative method, systematisation and conceptualisation of scientific ideas, classification and typifications, research object and subject modeling were used during the study. Results: the foundations and innovative potential of the sociocultural-interdeterminist dialogical meta-approach to social phenomenology analysis are given a thorough account. The teacher’s personality professional deformation main criteria are given (authoritativeness, rigidity, self-perception non-criticality, role expansionism and pedagogical indifference, the personality deformation operational definition is formulated. The concept of psychological interdeterminants of professional deformation is introduced, the process of interdetermination of personality’s deformation phenomenon is revealed, that is: interdependence of per¬sonal, environmental

    Argentine tango is a complex phenomenon, involving music, dancing and lifestyle, today practiced by hundreds of thousands of people worldwide. This is already a good reason for psychology to make it an object of study. Besides, studying tango could also help to develop a dialogical way of theorizing and a dialogical methodology, taking into account both the genetic historical and eso-systemic dimensions and the individual experiencing. As any other product of human psyche, tango creates an universal and abstract representation of life starting from very situated and individual acts. Such institutionalized representation, which is at the same time epistemological, ethical and aesthetical, becomes a tradition -that is the framework distanced from the individual immediate experience- within which the meaning of the experiences to be make sense in return. To illustrate this epistemological and methodological stance, a history of the development of tango as dialogical social object first is sketched. Then, an ethnographic study about the Self actuation in a community of Italian tango dancers is presented. Results show how participants construct and actuate their identities in a dialogue between their I-positions inside and outside tango community.

    Full Text Available Purpose: the notion of dialogic learning is on the basis of educational practices (Successful Educational Actions and projects (Schools as Learning Communities that are currently improving coexistence and promoting school success in more and more schools around the world. Physical Education has to find its place within this context and to define how to contribute to these aims from its specificity, as it is a subject in which the body and the movement have leading roles for learning and it is increasingly emphasizing the promotion of healthy habits. Due to all that, this article pretends to offer orientations to professionals and schools for building a more dialogic Physical Education. Design/methodology: a review of scientific literature on Physical Education and dialogic learning has been done starting from the results of the Juega Dialoga y Resuelve [Play, Dialogue and Solve] project (Spanish RTD National Plan and from the results obtained in the search for the topics “dialogic learning” and ”successful educational actions” in the ISI Web of Science. Findings: the results of the literature review show that the principles of dialogic learning and their practical development can be transferred to Physical Education and school sport in order to contribute to school success and to improve students’ and their communities’ health. Practical implications: orientations for professionals and schools to organize the practice of Physical Education and school sport in accordance with the principles of dialogic learning derive from the analysis. Social implications: the orientations promote school success for students and social cohesion and health for them and their communities. Originality/value: the article presents innovative elements for the organization of Physical Education and school sport that can be useful for teachers and other professionals.

    Full Text Available Abstract Background The online segmentation of spoken single sentences has repeatedly been associated with a particular event-related brain potential. The brain response could be attributed to the perception of major prosodic boundaries, and was termed Closure Positive Shift (CPS. However, verbal exchange between humans is mostly realized in the form of cooperative dialogs instead of loose strings of single sentences. The present study investigated whether listeners use prosodic cues for structuring larger contextually embedded utterances (i.e. dialogs like in single sentence processing. Methods ERPs were recorded from listeners (n = 22 when presented with question-answer dialogs in German. The prosody of the answer (target sentence either matched the context provided by a question or did not match the context question. Results CPS responses to the processing of the target sentences are elicited, first, when listeners encounter information comprising 'novelties', i.e. information not mentioned in the preceding question but facts corrected between context and target. Thereby it is irrelevant whether the actual prosody of the target sentence is in congruence with the informative status or not. Second, when listeners encounter target sentences which do not convey any novelties but only previously 'given' already known information, the structuring of the speech input is driven by prosody again. The CPS is then elicited when listeners perceive major prosodic boundaries similar as for the processing of context-free single sentences. Conclusion The study establishes a link between the on-line structuring of context-free (single sentences and context-embedded utterances (dialogs as measured by ERPs. Moreover, the impact of prosodic phrasing and accentuation on the perception of spoken utterances on and beyond sentence level is discussed.

    Full Text Available The purpose of this theoretical article is to highlight the role that dialogic pedagogy can play in critical multicultural education for pre-service teachers. The article starts by discussing the problematic that critical multicultural education poses in a democratic society that claims freedom of speech and freedom of expression as a basic tenet of democracy. Through investigating research findings in the field of critical multicultural education in higher education, the author argues that many of the educational approaches-including the ones that claim dialogue to be their main instructional tool- could be described as undemocratic, and thus have done more harm than good for the multicultural objectives. On the other hand, the author argues that dialogic pedagogy could be a better approach for critical multicultural education as it promises many opportunities for learning that do not violate the students’ rights of freedom of expression and freedom of association. Throughout this paper, the author tries to clarify the difference between dialogic pedagogy and other conceptualizations of dialogue in critical multicultural education arguing for the better suitability of dialogic pedagogy for providing a safer learning environment that encompasses differing and at times conflicting voices.

    and estimation of parameters of interest. VACTIV can run on any standard modern laptop. Reasons for the new version: At the time of its creation (1999) VACTIV was seemingly the first attempt to apply the newest programming languages and styles to systems of spectrum analysis. Its goal was to both get a convenient and efficient technique for data processing, and to elaborate the formalism of spectrum analysis in terms of classes, their properties, their methods and events of an object-oriented programming language. Summary of revisions: Compared with ACTIV, VACTIV preserves all the mathematical algorithms, but provides the user with all the benefits of an interface, based on a graphical dialog. It allows him to make a quick intervention in the work of the program; in particular, to carry out the on-line control of the fitting process: depending on the intermediate results and using the visual form of data representation, to change the conditions for the fitting and so achieve the optimum performance, selecting the optimum strategy. To find the best conditions for the fitting one can compress the spectrum, delete the blunders from it, smooth it using a high-frequency spline filter and build the background using a low-frequency spline filter; use not only automatic methods for the blunder deletion, the peak search, the peak model forming and the calibration, but also use manual mouse clicking on the spectrum graph. Restrictions: To enhance the reliability and portability of the program the majority of the most important arrays have a static allocation; all the arrays are allocated with a surplus, and the total pool of the program is restricted only by the size of the computer virtual memory. A spectrum has the static size of 32 K real words. The maximum size of the least-square matrix is 314 (the maximum number of fitted parameters per one analyzed spectrum interval, not for the whole spectrum), from which it follows that the maximum number of peaks in one spectrum

The goal of the paper is not to describe and analyze the dialogue approach rather explain what inner developments in the pragmatics paradigm have made it necessary to move in a dialogic direction, specifically emphasizing the importance of evaluating speaker meaning from the perspective of the speaker rather than from the perspective of the hearer and the double role of the interlocutor (speaker-hearer.

    Science.gov (United States)

    Hermans, Hubert J M

    2012-01-01

    Dialogical Self Theory is a recent development in the social sciences, based on a conception of the self as a society of mind. In this conception, the self is considered as extended to significant others in the environment, who populate the self as a dynamic multiplicity of I-positions between which dialogical or monological relationships may emerge. While from a spatial perspective the self is engaged in a process of positioning and counterpositioning in a globalizing society, from a temporal point of view the self is part of a process of positioning and repositioning in collective history and personal development. Some phenomena that are necessary for the understanding of the dialogical self are discussed: dominance and social power, the processes of globalization and localization, the experience of uncertainty and possible reactions to uncertainty in a globalizing world. Finally, the different contributions of this special issue are placed in the context of the presented conceptual framework. Copyright © 2012 Wiley Periodicals, Inc., A Wiley Company.

  4. Racial quotas in letters from readers of the “Caros Amigos” magazine: a dialogic perspective

    Full Text Available In this article we intend to demonstrate some results obtained in our dissertation, which was presented in the second semester of 2011. In the research, we analyzed texts from printed media inserted in a discursive chain of conflicts and clashes, a real platform for polemicconcerning the system of quotas in Brazil. Our purpose is to analyze the way in which the dialogic interactions are generated among the participants of the discursive event: how the author dialogues with the object of discourse and with the addressee, having as the basis for our work the Bakhtin Circle’s dialogical theory of discourse. The results highlight the fact that the positioning assumed by the interlocutors is built from the value attributed to its construction by the other; the clash among the interlocutors is constitutive of the utterances; and the dialogic analysis of the media utterances contributes to a better understanding of the social nature of discourse and of the themes which are relevant to society, in this case, the quotas.

  5. The Embodied Attunement of Therapists and a Couple within Dialogical Psychotherapy: An Introduction to the Relational Mind Research Project.

    In dialogical practice, therapists seek to respond to the utterances of clients by including in their own response what the client said. No research so far exists on how, in dialogs, therapists and clients attune themselves to each other with their entire bodies. The research program The Relational Mind is the first to look at dialog in terms of both the outer and the inner dialogs of participants (clients and therapists), observed in parallel with autonomic nervous system (ANS) measurements. In the ANS, the response occurs immediately, even before conscious thought, making it possible to follow how participants in a multiactor dialog synchronize their reactions and attune themselves to each other. The couple therapy case presented in this article demonstrates how attunement is often not a simple "all at the same time" phenomenon, but rather a complex, dyadic or triadic phenomenon which changes over time. In the case presented, there was strong synchrony between one therapist and one client in terms of their arousal level throughout the therapy session. It was also observed that high stress could occur when someone else was talking about something related to the participant, or if that person mirrored the participant's words. Overall, it seems that in evaluating the rhythmic attunement between therapists and clients it is not enough to look at single variables; instead, integrated information from several channels is needed when one is seeking to make sense of the embodiment. © 2015 Family Process Institute.

    Large numbers of patients with psychosis have regular meetings with key clinicians in the community. There is little evidence on how these meetings should be conducted to be therapeutically effective. DIALOG, a computer mediated procedure, was shown to improve outcomes in a European multi-centre trial. DIALOG structures the patient-clinician communication and makes it patient-centred, but does not guide clinicians as to how to respond to patients' concerns. DIALOG has been further developed into DIALOG+, which uses advanced software and, additionally, provides a four step approach--based on a solution focused model--for addressing patients' concerns. We designed a cluster randomised controlled trial to test the effectiveness of DIALOG+ in improving treatment outcomes of patients with psychosis in the community. Key workers are recruited from community mental health teams in East London and randomly allocated to either the intervention or control group. Out of their case loads, we identify patients with schizophrenia (F 20-29) and a moderate or lower level of subjective quality of life (MANSA score workers. Key workers in the intervention group are trained in using DIALOG+ and use it with each patient over a six-month period. Control patients rate their satisfaction with life and treatment on a tablet to control for the effect of regular ratings and the use of modern technology. We are recruiting up to 42 key workers to reach a total sample size of 180 patients. Clinical and social outcomes including costs are assessed after 3, 6 and 12 months. Primary outcome is subjective quality-of-life at 6 months. The trial aims to evaluate the effectiveness of a novel intervention (DIALOG+) which uses modern technology to support routine patient-clinician meetings in community care, makes the communication patient centred and guides patients and clinicians to address concerns. DIALOG+ is a generic and widely applicable intervention. If shown as effective, it can be used to

  14. A Software for the Analysis of Scripted Dialogs Based on Surface Markers

    Directory of Open Access Journals (Sweden)

    2003-04-01

    Full Text Available Most information systems that deal with natural language texts do not tolerate much deviation from their idealized and simplified model of language. Spoken dialog is notoriously ungrammatical however. Because the MAREDI project focuses in particular on the automatic analysis of scripted dialogs, we needed to develop a robust capacity to analyze transcribed spoken language. This paper presents the main elements of our approach, which is based on exploiting surface markers as the best route to the semantics of the conversation modelled. We highlight the foundations of our particular conversational model and give an overview of the MAREDI system. The latter consists of three key modules, which are 1 a connectionist network to recognise speech acts, 2 a robust syntactic parser, and 3 a semantic analyzer. These three modules are fully implemented in Prolog and C++ and have been packaged into an integrated software.

  18. Dentin matrix degradation by host Matrix Metalloproteinases: inhibition and clinical perspectives towards regeneration.

    Directory of Open Access Journals (Sweden)

    Catherine eChaussain

    2013-11-01

    Full Text Available Bacterial enzymes have long been considered solely accountable for the degradation of the dentin matrix during the carious process. However, the emerging literature suggests that host-derived enzymes, and in particular the matrix metalloproteinases (MMPs contained in dentin and saliva can play a major role in this process by their ability to degrade the dentin matrix from within. These findings are important since they open new therapeutic options for caries prevention and treatment. The possibility of using MMP inhibitors to interfere with dentin caries progression is discussed. Furthermore, the potential release of bioactive peptides by the enzymatic cleavage of dentin matrix proteins by MMPs during the carious process is discussed. These peptides, once identified, may constitute promising therapeutical tools for tooth and bone regeneration.

    This chapter builds on Dialogical Self Theory to investigate the identity development of adolescents growing up in multicultural societies. Their cultural identity is not only compounded by the rapid cultural changes associated with globalization, but also by the paradoxical revival of cultural traditions which the large-scale compression of time and space has incited at local levels of society. Dialogical Self Theory, which is based on the metaphor of the self as a "society of mind," helps to understand the dilemmas of tradition and postmodernity, of localization and globalization, within the self of individual youngsters.

    Directory of Open Access Journals (Sweden)

    V. A. Bulanov

    2014-01-01

    Full Text Available Rapidly developing data transmission technologies result in making the network equipment modernization inevitable. There are various options to upgrade the SDH networks, for example, by increasing the capacity of network overloaded sites, the entire network capacity by replacement of the equipment or by creation of a parallel network, by changing the network structure with the organization of multilevel hierarchy of a network, etc. All options vary in a diversity of parameters starting with the solution cost and ending with the labor intensiveness of their realization. Thus, there are no certain standard approaches to the rules to choose an option for the network development. The article offers the technique for choosing the SHD network upgrade based on method of expert evaluations using as a tool the software complex that allows us to have quickly the quantitative characteristics of proposed network option. The technique is as follows:1. Forming a perspective matrix of services inclination to the SDH networks.2. Developing the several possible options for a network modernization.3. Formation of the list of criteria and a definition of indicators to characterize them by two groups, namely costs of the option implementation and arising losses; positive effect from the option introduction.4. Criteria weight coefficients purpose.5. Indicators value assessment within each criterion for each option by each expert. Rationing of the obtained values of indicators in relation to the maximum value of an indicator among all options.6. Calculating the integrated indicators of for each option by criteria groups.7. Creating a set of Pareto by drawing two criteria groups of points, which correspond to all options in the system of coordinates on the plane. Option choice.In implementation of point 2 the indicators derivation owing to software complex plays a key role.

    Directory of Open Access Journals (Sweden)

    Miriam Bauab Puzzo

    2013-06-01

    Full Text Available This article presents a reading of the poem “Chorinho”, that integrates the work Vaga Música (1942 by Cecilia Meireles,in the perspective of dialogical discursive analysis of Bakhtin’s Circle. We take as reference the concepts of responsiveness and accountability that underlie Bakhtin’s reflections in his essay “Hacia uma filosofia del acto ético” (1997 about art, pointing dialogical relations established between the poetic text and social context, pointing as first reference the lyrical poem and Cecilia Meireles’s poetic proposal. After, from the musical leitmotif of the title and the suggestive poetic images we can see the conflict of self-lyrical, that demonstrates the dialogue between the liric self and the socio-historical context marked by the military dictatorship of Vargas and the Second World War. Contrary to current thinking that Cecilia Meireles distanced herself from the problems of her time, the analysis demonstrates that the subtlety of the poetic images, guided by the proximity of the popular musical universe, brings tension and existential suffering marked by adverse social context. Thus, the poem represents the author’s responsive and responsible attitude, in the bakhtinian perspective,fulfilling an aesthetic artistic proposal.

    Directory of Open Access Journals (Sweden)

    Fotini EGGLEZOU

    2016-01-01

    Full Text Available According to Bakhtin’s theory, an argumentative text encompasses qualities such as heteroglossia, polyphony and dialogism that enable the students’ transition from monologic to dialogic cognition of others’ ideas. Such a knowledge may conduce to the dialogic formation of argumentative writing and raise the students’ awareness on the argumentative genre. Influenced by Bakhtin’s theory, the following paper presents an intervention case-study in teaching argumentation conducted in a group of twenty four 12-year old students of a Greek primary school. Data has been gathered from class recordings of role playing games, dialogic interactions as well as from written argumentative texts. Results showed that the aforementioned activities conduced, first, to the introduction of counter-arguments and rebuttals in the students’ texts and, second, to the empowerment of their individual persuasive speech.

Data generation methods are SITE: Field work focuses on the development of the educational program "Care is in your hands" that takes place in two villages (Primary Care. Comarca Araba). Through a theoretical sampling involved people who are in a "mature-adult" life stage and three nurses with extensive experience in development health education programs. Participant observation where health education sessions are recorded in video and group reflection on action. To triangulate the data, have been made in-depth interviews with 4 participants. Carried out a content and discourse analysis. Participant and nurses' Previous Frameworks, and these last ones' discourses as well, reveal a current technical rationality (unidirectional, informative,.) yet in practice that perpetuates the role of passive recipient of care. Educational keys constructed from a viewpoint of Dialogic Learning emerge as elements that facilitate overcoming these previous frames limitations. Finally, Reflective Learning launched, has provided advance in professional knowledge and improve health education. Dialogical learning emerges as key to the training and empowerment, where we have seen how practical-reflexive, and not technical, rationality is meanly useful confronting ambiguous and complex situations of self-care practice and education.

    Branigan, Holly P; Pickering, Martin J; Pearson, Jamie; McLean, Janet F; Brown, Ash

    2011-10-01

    Five experiments examined the extent to which speakers' alignment (i.e., convergence) on words in dialog is mediated by beliefs about their interlocutor. To do this, we told participants that they were interacting with another person or a computer in a task in which they alternated between selecting pictures that matched their 'partner's' descriptions and naming pictures themselves (though in reality all responses were scripted). In both text- and speech-based dialog, participants tended to repeat their partner's choice of referring expression. However, they showed a stronger tendency to align with 'computer' than with 'human' partners, and with computers that were presented as less capable than with computers that were presented as more capable. The tendency to align therefore appears to be mediated by beliefs, with the relevant beliefs relating to an interlocutor's perceived communicative capacity. Copyright © 2011 Elsevier B.V.

  1. MAPPING CHILDREN'S POLITICS: SPATIAL STORIES, DIALOGIC RELATIONS AND POLITICAL FORMATION.

    Science.gov (United States)

    Elwood, Sarah; Mitchell, Katharyne

    2012-03-01

    This article confronts a persistent challenge in research on children's geographies and politics: the difficulty of recognizing forms of political agency and practice that by definition fall outside of existing political theory. Children are effectively "always already" positioned outside most of the structures and ideals of modernist democratic theory, such as the public sphere and abstracted notions of communicative action or "rational" speech. Recent emphases on embodied tactics of everyday life have offered important ways to recognize children's political agency and practice. However, we argue here that a focus on spatial practices and critical knowledge alone cannot capture the full range of children's politics, and show how representational and dialogic practices remain a critical element of their politics in everyday life. Drawing on de Certeau's notion of spatial stories, and Bakhtin's concept of dialogic relations, we argue that children's representations and dialogues comprise a significant space of their political agency and formation, in which they can make and negotiate social meanings, subjectivities, and relationships. We develop these arguments with evidence from an after-school activity programme we conducted with 10-13 year olds in Seattle, Washington, in which participants explored, mapped, wrote and spoke about the spaces and experiences of their everyday lives. Within these practices, children negotiate autonomy and self-determination, and forward ideas, representations, and expressions of agreement or disagreement that are critical to their formation as political actors.

    An improved nanophosphor scintillator liquid comprises nanophosphor particles in a liquid matrix. The nanophosphor particles are optionally surface modified with an organic ligand. The surface modified nanophosphor particle is essentially surface charge neutral, thereby preventing agglomeration of the nanophosphor particles during dispersion in a liquid scintillator matrix. The improved nanophosphor scintillator liquid may be used in any conventional liquid scintillator application, including in a radiation detector.

  5. The Mechanics of Embodiment: A Dialog on Embodiment and Computational Modeling

    Pezzulo, Giovanni; Barsalou, Lawrence W.; Cangelosi, Angelo; Fischer, Martin H.; McRae, Ken; Spivey, Michael J.

    Embodied theories are increasingly challenging traditional views of cognition by arguing that conceptual representations that constitute our knowledge are grounded in sensory and motor experiences, and processed at this sensorimotor level, rather than being represented and processed abstractly in an amodal conceptual system. Given the established empirical foundation, and the relatively underspecified theories to date, many researchers are extremely interested in embodied cognition but are clamoring for more mechanistic implementations. What is needed at this stage is a push toward explicit computational models that implement sensorimotor grounding as intrinsic to cognitive processes. In this article, six authors from varying backgrounds and approaches address issues concerning the construction of embodied computational models, and illustrate what they view as the critical current and next steps toward mechanistic theories of embodiment. The first part has the form of a dialog between two fictional characters: Ernest, the “experimenter,” and Mary, the “computational modeler.” The dialog consists of an interactive sequence of questions, requests for clarification, challenges, and (tentative) answers, and touches the most important aspects of grounded theories that should inform computational modeling and, conversely, the impact that computational modeling could have on embodied theories. The second part of the article discusses the most important open challenges for embodied computational modeling. PMID:21713184

  8. Modifying Dialogical Strategy in Asynchronous Critical Discussions for Cross-Strait Chinese Learners

    Directory of Open Access Journals (Sweden)

    Jean Yiching Chiu

    2014-09-01

    Full Text Available In this global era, critical thinking has become crucial for educators and learners. The purpose of this research was to explore how modifying a dialogical strategy in asynchronous online discussion forums impacted Chinese learners’ critical thinking. Due to the Chinese cultural impact of social harmony, the majority of learners tend to maintain silent and avoid critical discussions in instructional settings. The author deployed an affectively supportive model in a modified dialogical strategy to structure Chinese EFL learners’ asynchronous critical postings by probing and questioning while requiring labeling of each cross-referencing posting as Agree/Disagree/Challenge/New Perspective. The participants were two cohorts of similar cultural background but under different political systems in China and Taiwan, here engaged together in cultural interactions. This study employed two research methods: standardized critical thinking tests, and focus groups. Findings reveal that learners in both cohorts indicated some improvement in their critical thinking skills. Nevertheless, there remain affective and cultural issues. Future studies are thus recommended to further investigate the potential of an adaptive model to engage critical discussions with English native speakers and optimize critical thinking for Chinese learners in an EFL environment.

    Calls for embracing the potential and responsibility of occupational therapy to address socio-political conditions that perpetuate occupational injustices have materialized in the literature. However, to reach beyond traditional frameworks informing practices, this social agenda requires the incorporation of diverse epistemological and methodological approaches to support action commensurate with social transformative goals. Our intent is to present a methodological approach that can help extend the ways of thinking or frameworks used in occupational therapy and science to support the ongoing development of practices with and for individuals and collectives affected by marginalizing conditions. We describe the epistemological and theoretical underpinnings of a methodological approach drawing on Freire and Bakhtin's work. Integrating our shared experience taking part in an example study, we discuss the unique advantages of co-generating data using two methods aligned with this approach; dialogical interviews and critical reflexivity. Key considerations when employing this approach are presented, based on its proposed epistemological and theoretical stance and our shared experiences engaging in it. A critical dialogical approach offers one way forward in expanding occupational therapy and science scholarship by promoting collaborative knowledge generation and examination of taken-for-granted understandings that shape individuals assumptions and actions.

  10. Beyond equality and inequality in education: Bakhtinian dialogic ethics approach of human uniqueness to educational justice

    Directory of Open Access Journals (Sweden)

    Eugene Matusov

    2018-01-01

    Full Text Available In our essay, we challenge the hegemonic Kantian discourse of defining justice as equality (in a broader sense and injustice as inequality in education (and elsewhere. We argue that this discourse is based on the underlining assumption of replaceability and measurement of people and of educational practice itself. In contrast, we argue that people and their education are unique. Thus, it is necessary to develop an alternative notion of justice based on uniqueness and immeasurability of people and their education. We found that Bakhtin’s dialogic ethics framework is helpful for developing such an alternative approach. According to the Bakhtinian dialogic ethics, people are engaged in self-contradictory deeds, charged with ethical tensions. These ethically problematic deeds must be challenged by others and the self in critical dialogue and must demand responses by the authors of the deeds striving to achieve justice. Taking responsibility is not merely a discursive process of answering – it is not “answerability” – but rather another ethic deed of defining ethically good or bad, defining quality and values, accepting blame, standing grounds, committing to fixing negative consequences, emotional sympathy, and so on. The process of challenging people’s deeds in critical dialogue and their taking (or not taking responsibility defines (injustice of people’s deeds. We examine two cases of educational injustice based on the Bakhtinian dialogic ethics framework of uniquness. We try to show that education and its justice are essentially authorial and, thus, unique processes. Even when justice involves measurable things like money, it is still about unique people with unique educational goals, interests, and needs in unique circumstances that these measurable resources afford. We consider a case of allocation of measurable resources as a compromise between the Kantian formulistic and the Bakhtinian dialogic ethics approaches. We conclude our

    2009-06-01

    The researchers involved in this study work at Exeter Health library and at the Complementary Medicine Unit, Peninsula School of Medicine and Dentistry (PCMD). Within this collaborative environment it is possible to access the electronic resources of three institutions. This includes access to AMED and other databases using different interfaces. The aim of this study was to investigate whether searching different interfaces to the AMED allied health and complementary medicine database produced the same results when using identical search terms. The following Internet-based AMED interfaces were searched: DIALOG DataStar; EBSCOhost and OVID SP_UI01.00.02. Search results from all three databases were saved in an endnote database to facilitate analysis. A checklist was also compiled comparing interface features. In our initial search, DIALOG returned 29 hits, OVID 14 and Ebsco 8. If we assume that DIALOG returned 100% of potential hits, OVID initially returned only 48% of hits and EBSCOhost only 28%. In our search, a researcher using the Ebsco interface to carry out a simple search on AMED would miss over 70% of possible search hits. Subsequent EBSCOhost searches on different subjects failed to find between 21 and 86% of the hits retrieved using the same keywords via DIALOG DataStar. In two cases, the simple EBSCOhost search failed to find any of the results found via DIALOG DataStar. Depending on the interface, the number of hits retrieved from the same database with the same simple search can vary dramatically. Some simple searches fail to retrieve a substantial percentage of citations. This may result in an uninformed literature review, research funding application or treatment intervention. In addition to ensuring that keywords, spelling and medical subject headings (MeSH) accurately reflect the nature of the search, database users should include wildcards and truncation and adapt their search strategy substantially to retrieve the maximum number of appropriate

    2013-10-01

    Full Text Available This essay reconstructs two “Sicilian chapters” of great success from the Dialogi by Gregorius Magnus which were enjoyed in the medieval era. These are the legend of Placido (Placido is a Benedict's young disciple mentioned in the Dialogi, which has Sicily as a background, as recounted by Pietro, Deacon of Montecassino between the XI and the XII centuries, and the Sicilian vulgarization of the work, carried out by Giovanni Campolo in the first half of the XIV century. The literary voyage of Placido and the work of Campolo are two excellent examples of the circulation and the fruition of an exemplary and authoritative text. Each highlights the complex intricacy of religion, culture and politics in the various systems of power and in the various historical settings that the medieval age explored.

    In an attempt to resolve the controversial issue of tectonic and hydrologic stability of the Yucca Mountain region, the National Academy of Sciences established a Panel on Coupled Hydrologic/Tectonic/HydrothermaI Systems. The Panel has recently released it's findings in a report entitled Ground Water at Yucca Mountain: How High Can It Rise? The representation of data and the scientific validity of this report was the subject of comprehensive evaluations and reviews which has led to correspondence between Dr. Charles Archarnbeau and Dr. Frank Press, the President of the National Academy of Sciences. All such correspondence prior to April 9, 1993 is covered by TRAC Special Report No. 5, open-quotes Dialogs on the Yucca Mountain Controversy.close quotes The present report represents a continuation of the dialog between Dr. Archambeau and Dr. Press; specifically the letter from Dr. Press to Dr. Archambeau dated April 9, 1993 and Archambeau's response to Press, dated August 19, 1993. In addition to the correspondence between Press and Archambeau, a series of recent reports by other investigators, referred to in the correspondence from Archambeau, are included in this report and document new data and inferences of importance for resolution of the question of suitability of the Yucca Mountain site as a high level nuclear waste repository. These reports also demonstrate that other scientists, not previously associated with the government's program at Yucca Mountain or the National Academy review of an aspect of that program, have arrived at conclusions that are different than those stated by the Academy review and DOE program scientists

    Dominguez Lara, Sergio Alexis

    2014-04-01

    Full Text Available The use of product-moment correlation of Pearson is common in most studies in factor analysis in psychology, but it is known that this statistic is only applicable when the variables related are in interval scale and normally distributed, and when are used in ordinal data may to produce a distorted correlation matrix . Thus is a suitable option using polychoric/tetrachoric matrices in item-level factor analysis when the items are in level measurement nominal or ordinal. The aim of this study was to show the differences in the KMO, Bartlett`s Test and Determinant of the Matrix, percentage of variance explained and factor loadings in depression trait scale of Depression Inventory Trait - State and the Neuroticism dimension of the short form of the Eysenck Personality Questionnaire -Revised, regarding the use of matrices polychoric/tetrachoric matrices and Pearson. These instruments was analyzed with different extraction methods (Maximum Likelihood, Minimum Rank Factor Analysis, Unweighted Least Squares and Principal Components, keeping constant the rotation method Promin were analyzed. Were observed differences regarding sample adequacy measures, as well as with respect to the explained variance and the factor loadings, for solutions having as polychoric/tetrachoric matrix. So it can be concluded that the polychoric / tetrachoric matrix give better results than Pearson matrices when it comes to item-level factor analysis using different methods.

    Full Text Available Bakunin’s Son, a short novel by Sergio Atzeni, is the perfect embodiment of Bakhtin’s theory of the dialogic novel. The author sets his stories and characters - mostly humble outcast defeated people - in his own homeland, Sardinia. The accurately planned structure as an interview to thirty-two people reflects a multifarious reality with its complex rules and mentality expressed through different points of view, languages and ideologies. The protagonist’s story may result contradictory according to the different opinions of people who met him. Also the choice of a hybrid language contributes to create a highly connoted cultural context. In Bakunin’s Son, in fact, the Italian and the Sardinian overlap in a manner that cannot be distinguished or graphically marked, since form and meaning are fused together.Key words: dialogic novel, hybrid language.O filho de Bakunin, um romance polifónico de Sergio AtzeniO romance breve de Sergio Atzeni, O filho de Bakunin, è a perfeita exemplificação da teoria bachtininana do romance polifónico. O autor insere as histórias e as persona gens, geralmente abatidas, pessoas humildes e marginalizadas, na sua terra natal, a Sardenha. A história è estruturada na forma de entrevista a trinta e duas persona gens que com os seus pontos de vista criam una realidade multi-facetada e subjectiva. A vida de Tullio Saba, o protagonista, está narrada às vezes em modo contraditório e, por isso, os factos podem ser divergentes nas opiniões de quem esteve mais ou menos em contacto directo com ele. O uso característico de um instrumento linguístico híbrido, a meio caminho entre o italiano e o sardo, conota não somente o léxico mas também a estruturação inteira do discurso que atinge o efeito final pretendido pelo autor de descrever uma diversa ealidade antropológico-cultural.Palavras chave: romance polifónico, instrumento linguístico híbrido

  9. MAPPING CHILDREN’S POLITICS: SPATIAL STORIES, DIALOGIC RELATIONS AND POLITICAL FORMATION

    Science.gov (United States)

    Elwood, Sarah; Mitchell, Katharyne

    2015-01-01

    This article confronts a persistent challenge in research on children’s geographies and politics: the difficulty of recognizing forms of political agency and practice that by definition fall outside of existing political theory. Children are effectively “always already” positioned outside most of the structures and ideals of modernist democratic theory, such as the public sphere and abstracted notions of communicative action or “rational” speech. Recent emphases on embodied tactics of everyday life have offered important ways to recognize children’s political agency and practice. However, we argue here that a focus on spatial practices and critical knowledge alone cannot capture the full range of children’s politics, and show how representational and dialogic practices remain a critical element of their politics in everyday life. Drawing on de Certeau’s notion of spatial stories, and Bakhtin’s concept of dialogic relations, we argue that children’s representations and dialogues comprise a significant space of their political agency and formation, in which they can make and negotiate social meanings, subjectivities, and relationships. We develop these arguments with evidence from an after-school activity programme we conducted with 10–13 year olds in Seattle, Washington, in which participants explored, mapped, wrote and spoke about the spaces and experiences of their everyday lives. Within these practices, children negotiate autonomy and self-determination, and forward ideas, representations, and expressions of agreement or disagreement that are critical to their formation as political actors.

    2014-03-01

    There is little information in the literature describing how students learn qualitative research. This article describes an approach to learning that is based on the pedagogical approach of Dinkins' Socratic-Hermeneutic Shared Inquiry. This approach integrates shared dialog as an essential aspect of learning. The qualitative pedagogy described in this article focused on three questions: What is knowing in qualitative research? How do we come to know qualitative research? What can we do with qualitative research? Students learned the basics of qualitative research within a context that fostered interpretive inquiry. In this way, the course framework mirrored the combination of interviewing, storytelling, and journeying toward understanding that constitute qualitative research. © 2013.

  13. OLS Dialog: An open-source front end to the Ontology Lookup Service

    Directory of Open Access Journals (Sweden)

    Eidhammer Ingvar

    2010-01-01

    Full Text Available Abstract Background With the growing amount of biomedical data available in public databases it has become increasingly important to annotate data in a consistent way in order to allow easy access to this rich source of information. Annotating the data using controlled vocabulary terms and ontologies makes it much easier to compare and analyze data from different sources. However, finding the correct controlled vocabulary terms can sometimes be a difficult task for the end user annotating these data. Results In order to facilitate the location of the correct term in the correct controlled vocabulary or ontology, the Ontology Lookup Service was created. However, using the Ontology Lookup Service as a web service is not always feasible, especially for researchers without bioinformatics support. We have therefore created a Java front end to the Ontology Lookup Service, called the OLS Dialog, which can be plugged into any application requiring the annotation of data using controlled vocabulary terms, making it possible to find and use controlled vocabulary terms without requiring any additional knowledge about web services or ontology formats. Conclusions As a user-friendly open source front end to the Ontology Lookup Service, the OLS Dialog makes it straightforward to include controlled vocabulary support in third-party tools, which ultimately makes the data even more valuable to the biomedical community.

  15. Expansion of Parents' Undetermined Experience in Socioeducational Programs: Extending the Dialogical Self Theory.

    Science.gov (United States)

    Boulanger, Dany

    2017-12-01

    The Dialogic Self Theory (DST-Hermans et al. Integrative Psychology and Behavioral Sciences, 51(4), 1-31, 2017) is extended here in its dynamic aspects through focusing on the notions of indeterminacy, emptiness and movement. Linking with Husserl, I propose moving the dialogical self (DS) from a clear position in the "repertory of the Self" to an undetermined horizon. This makes it possible to introduce "holes" (emptiness) into the schematic representation of the "repertory of the Self". Yet Husserl's concept of horizon seems to focus too much on making the indeterminable determinate. To overcome this limit, I incorporate Bergson's concept of empty form into the DST. This enables conceptualising the extension and emergence of horizon. Extending Bergson's concept of organisation, it is possible to see how the expansion of the horizon in a movement of globalisation does not necessarily entail the disorganisation of the DS but rather to its further organisation. Extending the system of DS by Hermans et al. Integrative Psychology and Behavioral Sciences, 51(4), 1-31, (2017), I open by suggesting that movements are both horizontal (between people) and vertical (between the person, the institutions and the norms) connectors.

    Directory of Open Access Journals (Sweden)

    Arthur W. Frank

    2002-03-01

    Full Text Available Narrative analysis is presented as continuous with personal storytelling in the work of remoralizing what Weber identified as disenchanted modernity. Critics of contemporary storytelling seem to misunderstand what kind of authenticity of self is expressed in stories. Against those whom Charles Taylor calls “knockers” of the idea of personal authenticity, this article affirms authenticity, but in terms that are dialogical: authenticity is created in the process of storytelling, it is not a precondition of the telling, and authenticity remains in process. This authenticity is shown to have an affinity with democratic politics, in contrast to the neo-liberal affinity of the knocker position.

  17. Therapeutic change, innovative moments and the reconceptualization of the self : a dialogical account

    OpenAIRE

    Gonçalves, Miguel M.; Ribeiro, António P.

    2012-01-01

    Innovative moments (IMs) are exceptions toward the problematic self-narrative that brought the client to therapy, which emerge in the therapeutic conversation. Dialogically, an IM might be conceived as an expression of an alternative I-position which challenges the dominance of problematic voices, thus having the potential to transform the self-narrative as they are expanded and elaborated. Reconceptualization is a particular type of IM which usually emerges in the middle of th...

    Seedorf, Jan; Beckers, Kristian; Huici, Felipe

    The Session Initiation Protocol (SIP) is widely used for signaling in multimedia communications. However, many SIP implementations are still in their infancy and vulnerable to malicious messages. We investigate flaws in the SIP implementations of eight phones, showing that the deficient verification of SIP dialogs further aggravates the problem by making it easier for attacks to succeed. Our results show that the majority of the phones we tested are susceptible to these attacks.

  5. Family Involvement as a Priority Element for an Educational Action Based on Dialogic Learning

    Science.gov (United States)

    Valls, Mercè Pañellas; de Nicolás, Montserrat Alguacil; Torremorell, Maria Carme Boqué

    In our society, there is a need for a critical reflection on education and the tasks to be developed by every agent. The family and school are the two main socializing settings of children and adolescents and, therefore, their joint responsibility in their education is a commitment that should be established in an atmosphere of confidence and harmony in order to tend towards a learning community model based on dialogic learning.

  6. Collective stories and well-being: using a dialogical narrative approach to understand peer relationships among combat veterans experiencing post-traumatic stress disorder.

    Caddick, Nick; Phoenix, Cassandra; Smith, Brett

    2015-03-01

    Using a dialogical narrative approach, this original research explored how combat veterans experiencing post-traumatic stress disorder made sense of peer relationships with other veterans and what effects these relationships had on their well-being. Interviews and participant observations were conducted with 15 male combat veterans (aged 27-60 years) and one member of the civilian emergency services, the majority of whom were diagnosed with post-traumatic stress disorder following traumatic exposure in a range of armed conflicts. All participants were part of a surfing charity for veterans experiencing post-traumatic stress disorder. Data were rigorously analysed using a dialogical narrative analysis (DNA). Findings revealed the collective story that veterans used to make sense of peer relationships within the group. This collective story worked for the veterans to shape their experiences of well-being by fostering camaraderie, stimulating deeper connections and countering the negative effects of post-traumatic stress disorder. Potential therapeutic effects of the collective story were also identified. This article extends previous knowledge on combat veterans and social relationships and advances the field of narrative health psychology through the empirical application of a sophisticated dialogical narrative approach. © The Author(s) 2015.

    Full Text Available Managing customer loyalty becomes an important activity in marketing management. One of the reasons is that loyal consumers tend to make good financial performances to producer. Unfortunately, gaining a loyal customer is not a trivial activity since there are gaps to understand consumer experience comprehensively. To fulfill the gaps, this article explores imaginative experience of the community who adores its idol in the light of cultural perspective. The members of the community who adores its idol experience the imaginative experience. The author argues that those phenomena are cultural perspective, because they are meaningful to the members. Through narrative-dialogic ethnography, the author builds the concept of imaginative experience that through the imaginative media, the members do narrative-dialogic between “the realm of areal” and “the realm of afotik” then activate the imaginative relations in “the realm of aktinik”. Every member constructs its imaginative relations into imaginative constructions formed in a personal story. Managing imaginative experience could benefit the company. It can be the “Imaginative Experience Management” (IEM that accommodates imaginative consumers’ experiences with the company’s products deeply and sustainably through managing the story of its consumers’ imaginative experiences. It can also be linked to the customer loyalty programs. In this matter, IEM should be integrated with brand management.

  8. Oscillatory Brain Responses Reflect Anticipation during Comprehension of Speech Acts in Spoken Dialog

    Directory of Open Access Journals (Sweden)

    Rosa S. Gisladottir

    2018-02-01

    Full Text Available Everyday conversation requires listeners to quickly recognize verbal actions, so-called speech acts, from the underspecified linguistic code and prepare a relevant response within the tight time constraints of turn-taking. The goal of this study was to determine the time-course of speech act recognition by investigating oscillatory EEG activity during comprehension of spoken dialog. Participants listened to short, spoken dialogs with target utterances that delivered three distinct speech acts (Answers, Declinations, Pre-offers. The targets were identical across conditions at lexico-syntactic and phonetic/prosodic levels but differed in the pragmatic interpretation of the speech act performed. Speech act comprehension was associated with reduced power in the alpha/beta bands just prior to Declination speech acts, relative to Answers and Pre-offers. In addition, we observed reduced power in the theta band during the beginning of Declinations, relative to Answers. Based on the role of alpha and beta desynchronization in anticipatory processes, the results are taken to indicate that anticipation plays a role in speech act recognition. Anticipation of speech acts could be critical for efficient turn-taking, allowing interactants to quickly recognize speech acts and respond within the tight time frame characteristic of conversation. The results show that anticipatory processes can be triggered by the characteristics of the interaction, including the speech act type.

  9. Voices of dialogue and directivity in family therapy with refugees: evolving ideas about dialogical refugee care.

    Science.gov (United States)

    De Haene, Lucia; Rober, Peter; Adriaenssens, Peter; Verschueren, Karine

    2012-09-01

    In this article, we reflect on our evolving ideas regarding a dialogical approach to refugee care. Broadening the predominant phased trauma care model and its engaging of directive expertise in symptom reduction, meaning making, and rebuilding connectedness, these developing dialogical notions involve the negotiation of silencing and disclosure, meaning and absurdity, hope and hopelessness in a therapeutic dialogue that accepts its encounter of cultural and social difference. In locating therapeutic practice within these divergent approaches, we argue an orientation on collaborative dialogue may operate together with notions from the phased trauma care model as heuristic background in engaging a polyphonic understanding of coping with individual and family sequelae of forced displacement. This locating of therapeutic practice, as informed by each perspective, invites us to remain present to fragments of therapeutic positioning that resonate power imbalance or appropriation in a therapeutic encounter imbued with a social context that silences refugees' suffering. In a clinical case analysis, we further explore these relational complexities of negotiating directive expertise and collaborative dialogue in the therapeutic encounter with refugee clients. © FPI, Inc.

  10. Monological versus dialogical consciousness: two epistemological views on the use of theory in clinical ethical practice.

    Science.gov (United States)

    Ohnsorge, Kathrin; Widdershoven, Guy

    2011-09-01

    In this article, we argue that a critical examination of epistemological and anthropological presuppositions might lead to a more fruitful use of theory in clinical-ethical practice. We differentiate between two views of conceptualizing ethics, referring to Charles Taylors' two epistemological models: 'monological' versus 'dialogical consciousness'. We show that the conception of ethics in the model of 'dialogical consciousness' is radically different from the classical understanding of ethics in the model of 'monological consciousness'. To reach accountable moral judgments, ethics cannot be conceptualized as an individual enterprise, but has to be seen as a practical endeavor embedded in social interactions within which moral understandings are being negotiated. This view has specific implications for the nature and the role of ethical theory. Theory is not created in the individual mind of the ethicist; the use of theory is part of a joint learning process and embedded in a cultural context and social history. Theory is based upon practice, and serves practical purposes. Thus, clinical ethics support is both practical and theoretical. © 2011 Blackwell Publishing Ltd.

  11. Explicating Positionality: A Journey of Dialogical and Reflexive Storytelling

    Directory of Open Access Journals (Sweden)

    Celina Carter MN

    2014-02-01

    Full Text Available Qualitative researchers must be aware of and explicit about their social background as well as political and ideological assumptions. To facilitate this awareness, we believe that researchers need to begin with their own story as they seek to understand the stories of others. Taking into account the vulnerable act of storytelling, it is salient to consider how to share personal narratives in an authentic way within academic settings. In this article, we share our process and reflections of engaging in reflexive and dialogical storytelling. The focus of the article is the re-storying of one researcher's experience as she and her research team explore her emotions and positionality prior to conducting research on First Nations men's narratives of identity. We integrate a series of methodological lessons concerning reflexivity throughout the re-storying.

  12. Three approaches in the research field of ethnomodeling: emic (local, etic (global, and dialogical (glocal

    Daniel C. Orey

    2015-07-01

    Full Text Available The acquisition of both emic (local and etic (global knowledge is an alternative goal for the implementation of ethnomodeling research. Emic knowledge is essential for an intuitive and empathic understanding of mathematical ideas, procedures, and practices developed by the members of distinct cultural groups. It is essential for conducting effective ethnographic fieldwork. Furthermore, emic knowledge is a valuable source of inspiration for etic hypotheses. Etic knowledge is essential for cross-cultural comparisons, which are based on the components of ethnology. In this regard, such comparisons demand standard units and categories to facilitate communication. Dialogical (glocal is a third approach for ethnomodeling research that makes use of both emic and etic knowledge traditions through processes of dialogue and interaction. Ethnomodeling is defined as the study of mathematical phenomena within a culture because it is a social construct and is culturally bound. Finally, the objective of this article is to show how we have come to use a combination of emic, etic and dialogical (glocal approaches in our work in the area of ethnomodeling, which contributes to the acquisition of a more complete understanding of mathematical practices developed by the members of distinct cultural groups.

    2004-01-01

    In this paper a study on the sustainability of the main electricity generation options is presented. The study is based on a matrix of sustainability indicators developed in Switzerland. A revision of some sustainability studies performed in countries with certain energy diversity and with experience in nuclear power plants operation, is done. Studies, in general, are performed for the power plant life cycle, taking into account economic aspects, fuel prices impact on electricity generation costs, fuel reserves indicators and material consumption. Air emission, waste production and human health impact data are also presented. All the results lead to confirm that nuclear energy has a high degree of sustainability vis a vis other options based on fossil fuels and renewable. Finally some comments are presented in order to highlight the importance that nuclear energy might have in the sustainable development of Mexico. (Author)

  19. [Dialogy of Laughter: a new concept introducing joy for health promotion based on dialogue, laughter, joy and the art of the clown].

    Science.gov (United States)

    Matraca, Marcus Vinicius Campos; Wimmer, Gert; Araújo-Jorge, Tania Cremonini de

    2011-10-01

    The Dialogy of Laughter - a concept based upon the praxis of general health education performed with joy - is presented and discussed. Health is seen as a resource for life rather than a goal in life and promotion of health is a positive reaction leading to a broader, integrated and complex perception linking the environment, education, people, quality and style of life. Laughter can then be incorporated as a tool in health promotion as defended here. Considerations on dialogue, laughter, joy and the clown giving rise to the Dialogy of Laughter concept are presented. Dialogue, namely an exchange between two or more persons for the comprehension and transfer of ideas, is a methodology for joint thinking to produce new ideas and to share meaning, which is the essence of communication. Laughter is a universal phenomenon linked to aspects of culture, philosophy, history and health. It is dialogic, since through humor the comedy and the wit contained in each laugh, which is a communication code inherent to human nature, are revealed. Joy as a strategy for health promotion is highlighted and the art of the clown, using this art as an educational tool that can be integrated as a social technology, are adopted.

    2017-12-01

    In this article, we announce the development of a new version of the Java Superposition T-matrix App (JaSTA-2), to study the light scattering properties of porous aggregate particles. It has been developed using Netbeans 7.1.2, which is a java integrated development environment (IDE). The JaSTA uses double precision superposition T-matrix codes for multi-sphere clusters in random orientation, developed by Mackowski and Mischenko (1996). The new version consists of two options as part of the input parameters: (i) single wavelength and (ii) multiple wavelengths. The first option (which retains the applicability of older version of JaSTA) calculates the light scattering properties of aggregates of spheres for a single wavelength at a given instant of time whereas the second option can execute the code for a multiple numbers of wavelengths in a single run. JaSTA-2 provides convenient and quicker data analysis which can be used in diverse fields like Planetary Science, Atmospheric Physics, Nanoscience, etc. This version of the software is developed for Linux platform only, and it can be operated over all the cores of a processor using the multi-threading option.

  1. Advances in biomimetic regeneration of elastic matrix structures

    Science.gov (United States)

    Sivaraman, Balakrishnan; Bashur, Chris A.

    2012-01-01

    Elastin is a vital component of the extracellular matrix, providing soft connective tissues with the property of elastic recoil following deformation and regulating the cellular response via biomechanical transduction to maintain tissue homeostasis. The limited ability of most adult cells to synthesize elastin precursors and assemble them into mature crosslinked structures has hindered the development of functional tissue-engineered constructs that exhibit the structure and biomechanics of normal native elastic tissues in the body. In diseased tissues, the chronic overexpression of proteolytic enzymes can cause significant matrix degradation, to further limit the accumulation and quality (e.g., fiber formation) of newly deposited elastic matrix. This review provides an overview of the role and importance of elastin and elastic matrix in soft tissues, the challenges to elastic matrix generation in vitro and to regenerative elastic matrix repair in vivo, current biomolecular strategies to enhance elastin deposition and matrix assembly, and the need to concurrently inhibit proteolytic matrix disruption for improving the quantity and quality of elastogenesis. The review further presents biomaterial-based options using scaffolds and nanocarriers for spatio-temporal control over the presentation and release of these biomolecules, to enable biomimetic assembly of clinically relevant native elastic matrix-like superstructures. Finally, this review provides an overview of recent advances and prospects for the application of these strategies to regenerating tissue-type specific elastic matrix structures and superstructures.

    2017-10-01

    The availability of user-friendly software to annotate biological datasets and experimental details is becoming essential in data management practices, both in local storage systems and in public databases. The Ontology Lookup Service (OLS, http://www.ebi.ac.uk/ols) is a popular centralized service to query, browse and navigate biomedical ontologies and controlled vocabularies. Recently, the OLS framework has been completely redeveloped (version 3.0), including enhancements in the data model, like the added support for Web Ontology Language based ontologies, among many other improvements. However, the new OLS is not backwards compatible and new software tools are needed to enable access to this widely used framework now that the previous version is no longer available. We here present the OLS Client as a free, open-source Java library to retrieve information from the new version of the OLS. It enables rapid tool creation by providing a robust, pluggable programming interface and common data model to programmatically access the OLS. The library has already been integrated and is routinely used by several bioinformatics resources and related data annotation tools. Secondly, we also introduce an updated version of the OLS Dialog (version 2.0), a Java graphical user interface that can be easily plugged into Java desktop applications to access the OLS. The software and related documentation are freely available at https://github.com/PRIDE-Utilities/ols-client and https://github.com/PRIDE-Toolsuite/ols-dialog. © 2017 WILEY-VCH Verlag GmbH & Co.

    1999-01-01

    The end of the Cold War has created a legacy of surplus fissile materials (plutonium and highly enriched uranium) in the United States (U.S.) and the former Soviet Union. These materials pose a danger to national and international security. During the past few years, the U.S. and Russia have engaged in an ongoing dialog concerning the safe storage and disposition of surplus fissile material stockpiles. In January 1997, the Department of Energy (DOE) announced the U. S. would pursue a dual track approach to rendering approximately 50 metric tons of plutonium inaccessible for use in nuclear weapons. One track involves immobilizing the plutonium by combining it with high-level radioactive waste in glass or ceramic ''logs''. The other method, referred to as reactor-based disposition, converts plutonium into mixed oxide (MOX) fuel for nuclear reactors. The U.S. and Russia are moving ahead rapidly to develop and demonstrate the technology required to implement the MOX option in their respective countries. U.S. MOX fuel research and development activities were started in the 1950s, with irradiation of MOX fuel rods in commercial light water reactors (LWR) from the 1960s--1980s. In all, a few thousand MOX fuel rods were successfully irradiated. Though much of this work was performed with weapons-grade or ''near'' weapons-grade plutonium--and favorable fuel performance was observed--the applicability of this data for licensing and use of weapons-grade MOX fuel manufactured with modern fuel fabrication processes is somewhat limited. The U.S. and Russia are currently engaged in an intensive research, development, and demonstration program to support implementation of the MOX option in our two countries. This paper focuses on work performed in the U.S. and provides a brief summary of joint U.S./Russian work currently underway

  6. Peace talks: A “dialogical ethics” model of faculty–student collaboration in the undergraduate classroom

    Directory of Open Access Journals (Sweden)

    Jeffrey W. Murray

    2016-12-01

    Full Text Available At the 2015 CIDER conference on Higher Education Pedagogy, professors Abelson and Nelson discussed their intense and inspiring level of instructor–student collaboration, describing how they collaborate with their first-year students in the design of particular assignments and even overall course design at the unit level. This essay seeks to contribute to both our understanding and appreciation of such collaborative learning-centered strategies by applying a “dialogical ethics” model. The essay begins with an extended investigation of the ways in which the dramatistic philosophy of Kenneth Burke illuminates the grammatical, rhetorical, and dialogical mechanisms by which instructor–student collaboration fosters enhanced levels of student engagement in the process of education—including investment, ownership, and empowerment. In doing so, this essay explores how the notions of (i disparate grammars and recalcitrance, (ii consubstantiality and irony, and (iii dialogue of motives and peace treaty can elucidate the dynamics of instructor–student collaborative learning. Applying the ethical philosophy of Emmanuel Levinas, this essay then argues that instructor–student collaboration is an inherently ethical pedagogy. Finally, consistent with the general topic of collaboration and theoretical framework of dialogue, this essay concludes with a response from those who inspired it, Abelson and Nelson.

    2017-06-01

    Full Text Available The success of robotic agents in close proximity of humans depends on their capacity to engage in social interactions and maintain these interactions over periods of time that are suitable for learning. A critical requirement is the ability to modify the behavior of the robot contingently to the attentional and social cues signaled by the human. A benchmark challenge for an engaging social robot is that of storytelling. In this paper, we present an exploratory study to investigate dialogic storytelling—storytelling with contingent responses—using a child-friendly robot. The aim of the study was to develop an engaging storytelling robot and to develop metrics for evaluating engagement. Ten children listened to an illustrated story told by a social robot during a science fair. The responses of the robot were adapted during the interaction based on the children’s engagement and touches of the pictures displayed by the robot on a tablet embedded in its torso. During the interaction the robot responded contingently to the child, but only when the robot invited the child to interact. We describe the robot architecture used to implement dialogic storytelling and evaluate the quality of human–robot interaction based on temporal (patterns of touch, touch duration and spatial (motions in the space surrounding the robot metrics. We introduce a novel visualization that emphasizes the temporal dynamics of the interaction and analyze the motions of the children in the space surrounding the robot. The study demonstrates that the interaction through invited contingent responses succeeded in engaging children, although the robot missed some opportunities for contingent interaction and the children had to adapt to the task. We conclude that (i the consideration of both temporal and spatial attributes is fundamental for establishing metrics to estimate levels of engagement in real-time, (ii metrics for engagement are sensitive to both the group and

  9. Osteogenic Matrix Cell Sheets Facilitate Osteogenesis in Irradiated Rat Bone

    Full Text Available Reconstruction of large bone defects after resection of malignant musculoskeletal tumors is a significant challenge in orthopedic surgery. Extracorporeal autogenous irradiated bone grafting is a treatment option for bone reconstruction. However, nonunion often occurs because the osteogenic capacity is lost by irradiation. In the present study, we established an autogenous irradiated bone graft model in the rat femur to assess whether osteogenic matrix cell sheets improve osteogenesis of the irradiated bone. Osteogenic matrix cell sheets were prepared from bone marrow-derived stromal cells and co-transplanted with irradiated bone. X-ray images at 4 weeks after transplantation showed bridging callus formation around the irradiated bone. Micro-computed tomography images at 12 weeks postoperatively showed abundant callus formation in the whole circumference of the irradiated bone. Histology showed bone union between the irradiated bone and host femur. Mechanical testing showed that the failure force at the irradiated bone site was significantly higher than in the control group. Our study indicates that osteogenic matrix cell sheet transplantation might be a powerful method to facilitate osteogenesis in irradiated bones, which may become a treatment option for reconstruction of bone defects after resection of malignant musculoskeletal tumors.

    Dialogic book-sharing is an interactive form of shared reading. It has been shown in high income countries (HICs) to be of significant benefit to child cognitive development. Evidence for such benefit in low and middle income countries (LMICs) is scarce, although a feasibility study of our own produced encouraging findings. Accordingly, we aimed to establish the impact on child language and attention of providing training in dialogic booksharing to carers of infants in an impoverished South African community. We conducted a randomized controlled trial in Khayelitsha, an informal settlement in South Africa. Mothers of infants aged between 14 and 16 months were recruited and randomized to either 8 weeks of manualized training in dialogic book-sharing or a no-intervention control group. Independent assessments were made of infant language and attention at baseline and following training. The trial was registered (ISRCTN39953901). Ninety one carer-infant dyads were recruited and randomized to the intervention group (n = 49) or the control group (n = 42), 82 (90%) of whom were available for follow-up assessments. On a standardized carer report of infant vocabulary, compared to those in the control group, carers who received the intervention reported a significantly greater increase in the number of words understood by their infants as well as a larger increase in the number of words that their infant understood and could vocalize. Intervention group children also showed substantially greater gains on a measure of sustained attention. In line with evidence from HICs, a dialogic book-sharing programme delivered to an impoverished South African sample was shown to be of considerable benefit to the development of child language and focussed attention. The training programme, which is simple and inexpensive to deliver, has the potential to benefit child cognitive development in LMIC contexts where such development is commonly compromised. © 2014 Association for Child

    This chapter focuses on energy options as a means of managing exposure to energy prices. An intuitive approach to energy options is presented, and traditional definitions of call and put options are given. The relationship between options and swaps, option value and option exercises, commodity options, and option pricing are described. An end-user's guide to energy option strategy is outlined, and straight options, collars, participating swaps and collars, bull and bear spreads, and swaption are examined. Panels explaining the defining of basis risk, and discussing option pricing and the Greeks, delta hedging, managing oil options using the Black-Scholes model, caps, floors and collars, and guidelines on hedging versus speculation with options are included in the paper

  2. Fluoride-Salt-Cooled High-Temperature Reactor (FHR) with Silicon-Carbide-Matrix Coated-Particle Fuel

    International Nuclear Information System (INIS)

    Forsberg, C. W.; Snead, Lance Lewis; Katoh, Yutai

    2012-01-01

    The FHR is a new reactor concept that uses coated-particle fuel and a low-pressure liquid-salt coolant. Its neutronics are similar to a high-temperature gas-cooled reactor (HTGR). The power density is 5 to 10 times higher because of the superior cooling properties of liquids versus gases. The leading candidate coolant salt is a mixture of 7 LiF and BeF 2 (FLiBe) possessing a boiling point above 1300 C and the figure of merit ρC p (volumetric heat capacity) for the salt slightly superior to water. Studies are underway to define a near-term base-line concept while understanding longer-term options. Near-term options use graphite-matrix coated-particle fuel where the graphite is both a structural component and the primary neutron moderator. It is the same basic fuel used in HTGRs. The fuel can take several geometric forms with a pebble bed being the leading contender. Recent work on silicon-carbide-matrix (SiCm) coated-particle fuel may create a second longer-term fuel option. SiCm coated-particle fuels are currently being investigated for use in light-water reactors. The replacement of the graphite matrix with a SiCm creates a new family of fuels. The first motivation behind the effort is to take advantage of the superior radiation resistance of SiC compared to graphite in order to provide a stable matrix for hosting coated fuel particles. The second motivation is a much more rugged fuel under accident, repository, and other conditions.

  3. Matrix-directed differentiation of human adipose-derived mesenchymal stem cells to dermal-like fibroblasts that produce extracellular matrix.

    Commercially available skin substitutes lack essential non-immune cells for adequate tissue regeneration of non-healing wounds. A tissue-engineered, patient-specific, dermal substitute could be an attractive option for regenerating chronic wounds, for which adipose-derived mesenchymal stem cells (ADMSCs) could become an autologous source. However, ADMSCs are multipotent in nature and may differentiate into adipocytes, osteocytes and chondrocytes in vitro, and may develop into undesirable tissues upon transplantation. Therefore, ADMSCs committed to the fibroblast lineage could be a better option for in vitro or in vivo skin tissue engineering. The objective of this study was to standardize in vitro culture conditions for ADMSCs differentiation into dermal-like fibroblasts which can synthesize extracellular matrix (ECM) proteins. Biomimetic matrix composite, deposited on tissue culture polystyrene (TCPS), and differentiation medium (DM), supplemented with fibroblast-conditioned medium and growth factors, were used as a fibroblast-specific niche (FSN) for cell culture. For controls, ADMSCs were cultured on bare TCPS with either DM or basal medium (BM). Culture of ADMSCs on FSN upregulated the expression of differentiation markers such as fibroblast-specific protein-1 (FSP-1) and a panel of ECM molecules specific to the dermis, such as fibrillin-1, collagen I, collagen IV and elastin. Immunostaining showed the deposition of dermal-specific ECM, which was significantly higher in FSN compared to control. Fibroblasts derived from ADMSCs can synthesize elastin, which is an added advantage for successful skin tissue engineering as compared to fibroblasts from skin biopsy. To obtain rapid differentiation of ADMSCs to dermal-like fibroblasts for regenerative medicine, a matrix-directed differentiation strategy may be employed. Copyright © 2014 John Wiley & Sons, Ltd.

  6. Nonviolent communication: a dialogical retrieval of the ethic of authenticity.

    Science.gov (United States)

    Nosek, Marcianna

    2012-11-01

    Charles Taylor called for a retrieval of the ethic of authenticity that has been distorted in modern notions of autonomy and self-fulfillment. Via exchanges with others who matter to us, he proposed that human identities develop through the use of rich language draped in shared horizons of significance. The fostering of these dialogical ties beyond purely instrumental purposes, along with the recognition of the human dignity in all, may avert the fallen ideal of authenticity. Nonviolent communication affords the skillful dialogue with others cradled in a shared sense of significance and supports the development of a meaningful identity-one that is formed through the realization of what exists beyond the self. The purpose of this article is to argue that nonviolent communication facilitates the retrieval of the ethic of authenticity. Narratives from nursing students' journals on the use of nonviolent communication skills will be used to support the argument.

    Non-verbal communication has important implications for inter-individual relationships and negotiation success. However, to what extent humans can spontaneously use rhythm and prosody as a sole communication tool is largely unknown. We analysed human ability to resolve a conflict without verbal dialogs, independently of semantics. We invited pairs of subjects to communicate non-verbally using whistle sounds. Along with the production of more whistles, participants unwittingly used a subtle prosodic feature to compete over a resource (ice-cream scoops). Winners can be identified by their propensity to accentuate the first whistles blown when replying to their partner, compared to the following whistles. Naive listeners correctly identified this prosodic feature as a key determinant of which whistler won the interaction. These results suggest that in the absence of other communication channels, individuals spontaneously use a subtle variation of sound accentuation (prosody), instead of merely producing exuberant sounds, to impose themselves in a conflict of interest. We discuss the biological and cultural bases of this ability and their link with verbal communication. Our results highlight the human ability to use non-verbal communication in a negotiation process.

    Full Text Available This article focuses on an experience of in-service training carried out by a group of educators in literacy. The novelty of the undertaking lies in the methodological proposal analysed: using “chatting gatherings” as a methodological strategy, which supports critical reflection and the construction of knowledge, both in in-service training of professionals and in basic adult education. This experience reveals the nature of learning achieved through dialogical educational processes. Further, it allows us to observe the impact that they may have on the improvement of the professionals’ educational practices.

    The same chemical reaction may be different in terms of its position of the equilibrium (i.e., thermodynamics) and its kinetics when studied in different foods. The diversity in the chemical composition of food and in its structural organization at macro-, meso-, and microscopic levels, that is, the food matrix, is responsible for this difference. In this viewpoint paper, the multiple, and interconnected ways the food matrix can affect chemical reactivity are summarized. Moreover, mechanistic and empirical approaches to explain and predict the effect of food matrix on chemical reactivity are described. Mechanistic models aim to quantify the effect of food matrix based on a detailed understanding of the chemical and physical phenomena occurring in food. Their applicability is limited at the moment to very simple food systems. Empirical modeling based on machine learning combined with data-mining techniques may represent an alternative, useful option to predict the effect of the food matrix on chemical reactivity and to identify chemical and physical properties to be further tested. In such a way the mechanistic understanding of the effect of the food matrix on chemical reactions can be improved.

    Maffulli, Nicola; Longo, Umile Giuseppe; Loppini, Mattia; Spiezia, Filippo; Denaro, Vincenzo

    2010-01-01

    Tendon injuries can be acute or chronic, and caused by intrinsic or extrinsic factors, either alone or in combination. Tendinopathies are a common cause of disability in occupational medicine and account for a substantial proportion of overuse injuries in sports. Tendinopathy is essentially a failed healing response, with haphazard proliferation of tenocytes, abnormalities in tenocytes, with disruption of collagen fibres and subsequent increase in noncollagenous matrix. The scientific evidence base for managing tendinopathies is limited. What may appear clinically as an “acute tendinopathy” is actually a well advanced failure of a chronic healing response in which there is neither histologic nor biochemical evidence of inflammation. In this review we report the new options for the management of tendinopathy, including eccentric exercises, extracorporeal shockwave therapy, injections (intratendinous injections of corticosteroids, aprotinin, polidocanol platelet-rich plasma, autologous blood injection, high-volume injections) and surgery. Open surgery aims to excise fibrotic adhesions, remove areas of failed healing and make multiple longitudinal incisions in the tendon to detect intratendinous lesions, and to restore vascularity and possibly stimulate the remaining viable cells to initiate cell matrix response and healing. New surgical techniques aim to disrupt the abnormal neoinnervation to interfere with the pain sensation caused by tendinopathy. These procedures are intrinsically different from the classical ones in present use, because they do not attempt to address directly the pathologic lesion, but act only to denervate them. They include endoscopy, electrocoagulation, and minimally invasive stripping. Further randomized controlled trials are necessary to clarify better the best therapeutic options for the management of tendinopathy. PMID:24198540

    1990-06-01

    Full Text Available In light of discourse theory influenced by Bakhtin's concept of dialogism, the notion of voice has changed significantly so that we are invited to read discourse in a way that represents a departure from Bakhtin. The theories of François Flahault, Michel Pêchetut, and John Frow, who inquire into the importance of conditions of production of language, are used to explore the vain search for a subject-centered voice in Jorge Semprun's Le Grand voyage . The narrating subject Gerard experiences "homelessness" in discourse because he fails to find a voice of his own. His relationship to music and literature depends on an other; in invasion of self by the other occurs so that Gerard speaks only through alien voices that confront him throughout the narrative. In discourse a decentering occurs that is not present at the thematic level: the protagonist arrives at a destination, but discourse does not.

  15. Updated users' guide for SAMMY: multilevel R-matrix fits to neutron data using Bayes' equations. Revision 1

    International Nuclear Information System (INIS)

    Larson, N.M.

    1985-04-01

    In 1980 the multilevel multichannel R-matrix code SAMMY was released for use in analysis of neutron data at the Oak Ridge Electron Linear Accelerator. Since that time, SAMMY has undergone significant modifications: (1) User-friendly options have been incorporated to streamline common operations and to protect a run from common user errors. (2) The Reich-Moore formalism has been extended to include an optional logarithmic parameterization of the external R-matrix, for which any or all parameters may be varied. (3) The ability to vary sample thickness, effective temperature, matching radius, and/or resolution-broadening parameters has been incorporated. (4) To avoid loss of information (i.e., computer round-off errors) between runs, the ''covariance file'' now includes precise values for all variables. (5) Unused but correlated variables may be included in the analysis. Because of these and earlier changes, the 1980 SAMMY manual is now obsolete. This report is intended to be complete documentation for the current version of SAMMY. In August of 1984 the users' guide for version P of the multilevel multichannel R-matrix code SAMMY was published. Recently, major changes within SAMMY have led to the creation of version O, which is documented in this report. Among these changes are: (1) an alternative matrix-manipulation method for use in certain special cases; (2) division of theoretical cross-section generation and broadening operations into separate segments of the code; (3) an option to use the multilevel Breit-Wigner approximation to generate theoretical cross sections; (4) new input options; (5) renaming all temporary files as SAM...DAT; (6) more sophisticated use of temporary files to maximize the number of data points that may be analyzed in a single run; and (7) significant internal restructing of the code in preparation for changes described here and for planned future changes

    Full Text Available Starting from the critical review of various motivational frameworks of change that have been applied to the study of eating disorders, the present paper provides an alternative conceptualization of the change in psychotherapy presenting a single case study. We analysed six psychotherapeutic conversations with a bulimic patient and found out narratives for and against change. We read them in terms of tension between dominance and exchange in I-positions, as described by Hermans. These results indicate that the dialogical analysis of clinical discourse may be a useful method to investigate change from the beginning to the end of therapy.

  20. ReplacementMatrix: a web server for maximum-likelihood estimation of amino acid replacement rate matrices.

    Dang, Cuong Cao; Lefort, Vincent; Le, Vinh Sy; Le, Quang Si; Gascuel, Olivier

    2011-10-01

    Amino acid replacement rate matrices are an essential basis of protein studies (e.g. in phylogenetics and alignment). A number of general purpose matrices have been proposed (e.g. JTT, WAG, LG) since the seminal work of Margaret Dayhoff and co-workers. However, it has been shown that matrices specific to certain protein groups (e.g. mitochondrial) or life domains (e.g. viruses) differ significantly from general average matrices, and thus perform better when applied to the data to which they are dedicated. This Web server implements the maximum-likelihood estimation procedure that was used to estimate LG, and provides a number of tools and facilities. Users upload a set of multiple protein alignments from their domain of interest and receive the resulting matrix by email, along with statistics and comparisons with other matrices. A non-parametric bootstrap is performed optionally to assess the variability of replacement rate estimates. Maximum-likelihood trees, inferred using the estimated rate matrix, are also computed optionally for each input alignment. Finely tuned procedures and up-to-date ML software (PhyML 3.0, XRATE) are combined to perform all these heavy calculations on our clusters. http://www.atgc-montpellier.fr/ReplacementMatrix/ olivier.gascuel@lirmm.fr Supplementary data are available at http://www.atgc-montpellier.fr/ReplacementMatrix/

    A fast and efficient numerical method is proposed and analyzed for the valuation of American lookback options. American lookback option pricing problem is essentially a two-dimensional unbounded nonlinear parabolic problem. We reformulate it into a two-dimensional parabolic linear complementary problem (LCP) on an unbounded domain. The numeraire transformation and domain truncation technique are employed to convert the two-dimensional unbounded LCP into a one-dimensional bounded one. Furthermore, the variational inequality (VI) form corresponding to the one-dimensional bounded LCP is obtained skillfully by some discussions. The resulting bounded VI is discretized by a finite element method. Meanwhile, the stability of the semi-discrete solution and the symmetric positive definiteness of the full-discrete matrix are established for the bounded VI. The discretized VI related to options is solved by a projection and contraction method. Numerical experiments are conducted to test the performance of the proposed method.

    Americium is a strong contributor to the long term radiotoxicity of high activity nuclear waste. Transmutation by irradiation in nuclear reactors or Accelerator Driven System (ADS, subcritical reactors dedicated to transmutation) of long-lived nuclides like {sup 241}Am is therefore an option for the reduction of radiotoxicity of waste packages to be stored in a repository. In order to safely burn americium in a fast reactor or ADS, it must be incorporated in a matrix that could be metallic (CerMet target) or ceramic (CerCer target). One of the most promising matrix to incorporate Am is molybdenum. In order to address the issues (swelling, stability under irradiation, gas retention and release) of using Mo as matrix to transmute Am, two irradiation experiments have been conducted recently at the High Flux Reactor (HFR) in Petten (The Netherland) namely HELIOS and BODEX. The BODEX experiment is a separate effect test, where the molybdenum behaviour is studied without the presence of fission products using {sup 10}B to “produce” helium, the HELIOS experiment included a more representative fuel target with the presence of Am and fission product. This paper covers the results of Post Irradiation Examination (PIE) of the two irradiation experiments mentioned above where molybdenum behaviour has been deeply investigated as possible matrix to transmute americium (CerMet fuel target). The behaviour of molybdenum looks satisfying at operating temperature but at high temperature (above 1000 °C) more investigation should be performed.

  6. Analysis of Options Contract, Option Pricing in Agricultural Products

    Full Text Available Introduction: Risk is an essential component in the production and sale of agricultural products. Due to the nature of agricultural products, the people who act in this area including farmers and businesspersons encounter unpredictable fluctuations of prices. On the other hand, the firms that process agricultural products also face fluctuation of price of agricultural inputs. Given that the Canola is considered as one of the inputs of product processing factories, control of unpredictable fluctuations of the price of this product would increase the possibility of correct decision making for farmers and managers of food processing industries. The best available tool for control and management of the price risk is the use of future markets and options. It is evident that the pricing is the main pillar in every trade. Therefore, offering a fair price for the options will be very important. In fact, options trading in the options market create cost insurance stopped. In this way, which can reduce the risks of deflation created in the future, if the person entitled to the benefits of the price increase occurs in the future. Unlike the futures, market where the seller had to deliver the product on time, in the options market, there is no such compulsion. In addition, this is one of the strengths of this option contract, because if there is not enough product for delivery to the futures market as result of chilling, in due course, the farmers suffer, but in the options market there will be a loss. In this study, the setup options of rape, as a product, as well as inputs has been paid for industry. Materials and Methods: In this section. The selection criteria of the disposal of asset base for valuation of European put options and call option is been introduced. That for obtain this purpose, some characteristics of the goods must considered: 1-Unpredictable fluctuations price of underlying asset 2 -large underlying asset cash market 3- The possibility

  7. Mechanoregulatory tumor-stroma crosstalk in pancreatic cancer: Measurements of the effects of extracellular matrix mechanics on tumor growth behavior, and vice-versa, to inform therapeutics

    Celli, Jonathan; Jones, Dustin; El-Hamidi, Hamid; Cramer, Gwendolyn; Hanna, William; Caide, Andrew; Jafari, Seyedehrojin

    The rheological properties of the extracellular matrix (ECM) have been shown to play key roles in regulating tumor growth behavior through mechanotranduction pathways. The role of the mechanical microenvironment may be particularly important tumors of the pancreas, noted for an abundance of rigid fibrotic stroma, implicated in therapeutic resistance. At the same time, cancer cells and their stromal partners (e.g. tumor associated fibroblasts) continually alter the mechanical microenvironment in response to extracellular physical and biochemical cues as part of a two-way mechanoregulatory dialog. Here, we describe experimental studies using 3D pancreatic cell cultures with customized mechanical properties, combined with optical microrheology to provide insight into tumor-driven matrix remodeling. Quantitative microscopy provides measurements of phenotypic changes accompanying systematic variation of ECM composition in collagen and laminin-rich basement membrane admixtures, while analysis of the trajectories of passive tracer particles embedded in ECM report dynamic changes in heterogeneity, microstructure and local shear modulus accompanying both ECM stiffening (fibrosis) processes, and ECM degradation near invading cells.

    Full Text Available This study investigates the impact of implementing collaborative learning from a social and dialogical perspective on seventh graders’ interaction in an English as a foreign language classroom at a public school in Bogotá, Colombia. Thirty students participated in this action research where field notes, questionnaires, semi-structured interviews, and artifacts of students’ work were used to collect data during a complete academic year. Results show that taking a critical approach to language education and understanding collaborative learning as a social construction of knowledge can ignite opportunities for changing traditional teaching and learning practices where both the teacher and students take different roles, thus balancing classroom relations and interaction among participants and also promoting students’ empowerment.

    Full Text Available Long lasting conflict occurs in the absence of common ground which oversees the dynamics of the conflict. conflicts are representative of the interests of each group involved in taking the form of, one of which, opinion friction lead to anarchy. Such premises, specifically, occur in the conflict between Merigi Sakti people and PT. CBS pertaining mining system which, then, give its impact on other issues. The conflict requires dialogue as an instrument for transforming these interests in order to reconcile the conflicting groups to find  an agreement. Based on the background this article will elucidate how dialogue takes roles in conflict reconciliation process. The study in condition by using case study method—not only shows the friction that occurs but also the dialogic efforts which are important parts of communication in the conflict. Based on the data obtained, it can be seen that the dialogue moves from bottom to top, in the sense that Merigi Sakti people can manage their communities to unite against the mining system and deliver it structurally to the parties concerned.

    The general problem of effectively using interactive engagement in non-introductory physics courses remains open. We present a three-year study comparing different approaches to lecturing in an intermediate mechanics course at the Colorado School of Mines. In the first year, the lectures were fairly traditional. In the second year the lectures were modified to include Socratic dialogs between the instructor and students. In the third year, the instructor used a personal response system and Peer Instruction-like pedagogy. All other course materials were nearly identical to an established traditional lecture course. We present results from a new instructor-constructed conceptual survey, exams, and course evaluations. We observe little change in student exam performance as lecture techniques varied, though students consistently stated clickers were "the best part of the course" from which they "learned the most." Indeed, when using clickers in this course, students were considerably more likely to become engaged than students in CSM introductory courses using the same methods.

    Most of the academic teachers use four or five options per item of multiple choice question (MCQ) test as formative and summative assessment. Optimal number of options in MCQ item is a matter of considerable debate among academic teachers of various educational fields. There is a scarcity of the published literature regarding the optimum number of option in each item of MCQ in the field of medical education. To compare three options, four options, and five options MCQs test for the quality parameters - reliability, validity, item analysis, distracter analysis, and time analysis. Participants were 3 rd semester M.B.B.S. students. Students were divided randomly into three groups. Each group was given one set of MCQ test out of three options, four options, and five option randomly. Following the marking of the multiple choice tests, the participants' option selections were analyzed and comparisons were conducted of the mean marks, mean time, validity, reliability and facility value, discrimination index, point biserial value, distracter analysis of three different option formats. Students score more ( P = 0.000) and took less time ( P = 0.009) for the completion of three options as compared to four options and five options groups. Facility value was more ( P = 0.004) in three options group as compared to four and five options groups. There was no significant difference between three groups for the validity, reliability, and item discrimination. Nonfunctioning distracters were more in the four and five options group as compared to three option group. Assessment based on three option MCQs is can be preferred over four option and five option MCQs.

    Full Text Available Dialogic learning and interactive groups have proved to be a useful educational methodological approach in lifelong learning with adults. The principles of this approach stress the importance of dialogue and equal participation in every stage of the learning process – including the design of the training activities. This paper adopts these principles as the basis for a configurable template that can be integrated in runtime systems. The template is formulated as a meta-UoL which can be interpreted by IMS Learning Design players. This template serves as a guide to flexibly select and edit the activities at runtime (on the fly. The meta-UoL has been used successfully by two significant practitioners so as to create a real-life example, with positive and encouraging results.

    This report presents the performance characteristics of two ''two-stage'' fast spectrum fuel cycle options proposed to enhance uranium resource utilization and to reduce nuclear waste generation. One is a two-stage fast spectrum fuel cycle option of continuous recycle of plutonium (Pu) in a fast reactor (FR) and subsequent burning of minor actinides (MAs) in an accelerator-driven system (ADS). The first stage is a sodium-cooled FR fuel cycle starting with low-enriched uranium (LEU) fuel; at the equilibrium cycle, the FR is operated using the recovered Pu and natural uranium without supporting LEU. Pu and uranium (U) are co-extracted from the discharged fuel and recycled in the first stage, and the recovered MAs are sent to the second stage. The second stage is a sodium-cooled ADS in which MAs are burned in an inert matrix fuel form. The discharged fuel of ADS is reprocessed, and all the recovered heavy metals (HMs) are recycled into the ADS. The other is a two-stage FR/ADS fuel cycle option with MA targets loaded in the FR. The recovered MAs are not directly sent to ADS, but partially incinerated in the FR in order to reduce the amount of MAs to be sent to the ADS. This is a heterogeneous recycling option of transuranic (TRU) elements

    2002-01-01

    The program VACTIV - Visual ACTIV - has been developed for the analysis of gamma-ray spectra and is a standard graphical dialog based Windows XX application, driven by a menu, mouse and keyboard. On the one hand, it is a conversion of an existing Fortran program ACTIV to the DELPHI-5 language; on the other hand, it is a transformation of the sequential syntax of Fortran programming to a new object-oriented style, based on the organization of event interaction. Since VACTIV is seemingly the first attempt of applying the newest programming languages and styles to systems of spectrum analysis, the goal of its creation was both getting a convenient and efficient technique for data processing, their methods and events. Now the program is widely used for the processing of gamma-ray spectra in experiments on activation analysis

  20. Meaning Emergence in the Ecology of Dialogical Systems

    Directory of Open Access Journals (Sweden)

    Trasmundi Sarah Bro

    2016-12-01

    Full Text Available This article is an empirically based theoretical contribution to the investigation of meaningmaking in the ecology of human interaction and interactivity. It presents an ecological perspective on meaning-making that pivots on how agents pick up information directly in their organism-environment-system; i.e. as an activity that does not presuppose inner cognitive operations. We pursue this line of thought by presenting an analysis of how a doctor and a nurse make a decision about a specific medical procedure (catheterisation based on meaning-making activity. As we do not see meaning as a linguistic (symbolic or a cognitive (representational phenomenon external to an agent/user, but as emergent in coordinated interaction, we zoom in on how the practitioners recalibrate the organism-environmentsystem by shift ing between a multi-agentive mode and an individual mode. We use Cognitive Event Analysis to investigate how the agents oscillate between being a multi-agent-system with shared, tightly coordinated agency and a loosely coupled dialogical system where the individuals bring forth an understanding based on their professional backgrounds and expertise. On this view, an ecological approach to meaning-making takes a starting point in how local interaction is constrained by previous events, emergent affordances in the environment, and real-time inter-bodily dynamics. Accordingly, meaning-making is seen as a joint activity emerging from the system’s coordinative actions rather than as a result of individual interpretation of symbolic content.

  1. Exotic Options: a Chooser Option and its Pricing

    Directory of Open Access Journals (Sweden)

    Raimonda Martinkutė-Kaulienė

    2012-12-01

    Full Text Available Financial instruments traded in the markets and investors’ situation in such markets are getting more and more complex. This leads to more complex derivative structures used for hedging that are harder to analyze and which risk is harder managed. Because of the complexity of these instruments, the basic characteristics of many exotic options may sometimes be not clearly understood. Most scientific studies have been focused on developing models for pricing various types of exotic options, but it is important to study their unique characteristics and to understand them correctly in order to use them in proper market situations. The paper examines main aspects of options, emphasizing the variety of exotic options and their place in financial markets and risk management process. As the exact valuation of exotic options is quite difficult, the article deals with the theoretical and practical aspects of pricing of chooser options that suggest a broad range of usage and application in different market conditions. The calculations made in the article showed that the price of the chooser is closely correlated with the choice time and low correlated with its strike price. So the first mentioned factor should be taken into consideration when making appropriate hedging and investing decisions.

    European Union maintains an individual dialog with Russia about cooperation in energy sphere since joint summit in Paris in October 2000. Both sides agreed there to create four export groups: for energy strategy, investments, infrastructure and technologies, efficiency and ecology. European Union expects that Russia will unequivocally take over the obligations by creation of suitable climate for investors. European Union considers as key preconditions the restructuring of the largest national monopoles. These conditions are also the important component of asking strategy of EU by the discussions about integration of Russia to WTO. One of the most important requests of Brussels is the restructuring of Gazprom concern, what means its division to mining and transport part. Russian part refuses all steps in this sphere. Author analyses the strategic interests of Russian government and of president Putin by planning and mining of oil and gas as like as by investments to the pipelines and gas lines. International Energetic Agency (IEA) assumes that the investments to oil and gas mining in Russia will be around 330 million USD till 2030. The similar situation is also in oil sector. More than half of huge oil deposits with the highest output are already mined. The oil mining in Russia reached 421 million tons in 2003. According to pessimistic estimations the gas mining will reach from 550 to 560 billion m 3 in the following decades, according to optimistic scenario it can reach up to 730 billion m 3 per year. In this case the netto export of oil from Russia could rise from present around 175 billion m 3 to 280 billion m 3 in 2030. IEA warns that these plans should be fulfilled only if massive foreign investments enter this sector. IEA also warns before concerns of investors about Russian legislation, property protection, cooperative regulation and transparentness of undertaking. Proposed pipelines among Russia, Near East, Africa and European Union are shown

    In this paper a study on the sustainability of the main electricity generation options is presented. The study is based on a matrix of sustainability indicators developed in Switzerland. A revision of some sustainability studies performed in countries with certain energy diversity and with experience in nuclear power plants operation, is done. Studies, in general, are performed for the power plant life cycle, taking into account economic aspects, fuel prices impact on electricity generation costs, fuel reserves indicators and material consumption. Air emission, waste production and human health impact data are also presented. All the results lead to confirm that nuclear energy has a high degree of sustainability vis a vis other options based on fossil fuels and renewable. Finally some comments are presented in order to highlight the importance that nuclear energy might have in the sustainable development of Mexico. (Author)

    We study European options on the ratio of the stock price to its average and viceversa. Some of these options are traded in the Australian Stock Exchange since 1992, thus we call them Australian Asian options. For geometric averages, we obtain closed-form expressions for option prices. For arithmetic means, we use different approximations that produce very similar results.

    Full Text Available ABSTRACT: Psychoanalysis (theory and practice is alive and well in some parts of the world like France, Brazil, and Argentina, but in countries like Canada and the United States it struggles to surviveas it competes with other kinds of therapies. Psychoanalysts in these latter countries have been seeking to understand why psychoanalysis is "under siege" and to invent new, more relevant clinical and theoretical approaches. "What kind of psychoanalysis contributes best to the creation of a democratic mind?" is a (political question asked by some contemporary relational psychoanalysts. The objective of my article is to suggest some answers to this kind of question byexploring the lessons we might learn from the work of a few key thinkers: the members of the Bakhtin Circle, Freud, Derrida, and some relational psychoanalysts of today. Two underlying assumptions of my article are: 1 an agreement with Stephen Mitchell that the practice and theory of psychoanalysis should provide a better understanding of "the relational matrix that makes our individual consciousness possible"; 2 that the dialogic principle (as developed by Bakhtin, Tzvetan Todorov, and others can help achieve this goal. RESUMO: A Psicanálise (teoria e prática está viva e bem em algumas partes do mundo como, por exemplo, na França, Brasil e Argentina, mas em países tais como o Canadá e os Estados Unidos ela tem lutado para sobreviver uma vez que compete com outros tipos de terapias. Psicanalistas nesses últimos países têm procurado entender o porquê de a psicanálise encontrar-se 'sitiada' enquanto buscam formas novas e mais relevantes de abordagens clínicas e teóricas. "Que tipo de psicanálise contribui melhor para a criação de uma mente democrática?" é uma questão(política indagada por alguns psicanalistas relacionais contemporâneos.

    Full Text Available Traditional discounted cash-flows method for assessing projects assumes that investment decision is an irreversible one, which is not correct. Managers can and must reconsider their initial decision as the new information arises during the project life. This is managerial flexibility and it creates strategic value for a project, only if management takes advantage of the opportunities associated with an analyzed project. Real options represent a new approach in capital budgeting, using the theory of pricing financial options for investments in real assets. In this paper, we emphasize the characteristics and valuation methodologies of real options. The objective in the last section is pricing the option to delay and the option to abandon a project in construction materials field.

The methodology consisted the description of the videos, the selection of comments and further analysis based on the notion of dialogic language of Mikhail Bakhtin and the types of decoding Stuart Hall. We concluded that there was a large range of bodily practices and meanings related to them in the videos. Reception/interaction Internet provides a critical dialogue, congratulation, and suggestive questioning on the videos.

  11. The Decision Support Matrix (DSM) Approach to Reducing Risk of Flooding and Water Pollution in Farmed Landscapes

    2014-05-01

    Intense farming plays a key role in contributing to problems such as increased flood risk, soil erosion and poor water quality. This means that there is great potential for agricultural practitioners to play a major part in reducing multiple risks through better land-use management. Greater understanding by farmers, land managers, practitioners and policy-makers of the ways in which farmed landscapes contribute to risks and the ways in which those risks might be mitigated can be an essential component in improving practice. The Decision Support Matrix (DSM) approach involves the development of a range of visualization and communication tools to help compare the risks associated with different farming practices and explore options to manage runoff. DSMs are simple decision support systems intended for use by the non-expert which combine expert hydrological evidence with local knowledge of runoff patterns. They are developed through direct engagement with stakeholders, ensuring that the examples and language used makes sense to end-users. A key element of the tools is that they show the current conditions of the land and describe extremes of land-use management within a hydrological and agricultural land-management context. The tools include conceptual models of a series of pre-determined runoff scenarios, providing the end-user with a variety of potential land management practices and runoff management options. Visual examples of different farming practices are used to illustrate the impact of good and bad practice on specific problems such as nutrient export or risk of flooding. These show both how current conditions cause problems downstream and how systems are vulnerable to changes in climate and land-use intensification. The level of risk associated with a particular land management option is represented by a mapping on a two- or three-dimensional matrix. Interactive spreadsheet-based tools are developed in which multiple questions allow the user to explore

Tendinopathies are a common cause of disability in occupational medicine and account for a substantial proportion of overuse injuries in sports. Tendinopathy is essentially a failed healing response, with haphazard proliferation of tenocytes, abnormalities in tenocytes, with disruption of collagen fibres and subsequent increase in noncollagenous matrix. The scientific evidence base for managing tendinopathies is limited. What may appear clinically as an “acute tendinopathy” is actually a well advanced failure of a chronic healing response in which there is neither histologic nor biochemical evidence of inflammation. In this review we report the new options for the management of tendinopathy, including eccentric exercises, extracorporeal shockwave therapy, injections (intratendinous injections of corticosteroids, aprotinin, polidocanol platelet-rich plasma, autologous blood injection, high-volume injections and surgery. Open surgery aims to excise fibrotic adhesions, remove areas of failed healing and make multiple longitudinal incisions in the tendon to detect intratendinous lesions, and to restore vascularity and possibly stimulate the remaining viable cells to initiate cell matrix response and healing. New surgical techniques aim to disrupt the abnormal neoinnervation to interfere with the pain sensation caused by tendinopathy. These procedures are intrinsically different from the classical ones in present use, because they do not attempt to address directly the pathologic

    Although there have been enormous investments into English education all around the world, not many differences have been made to change the English instruction style. Considering the shortcomings for the current teaching-learning methodology, we have been investigating advanced computer-assisted language learning (CALL) systems. This paper aims at summarizing a set of POSTECH approaches including theories, technologies, systems, and field studies and providing relevant pointers. On top of the state-of-the-art technologies of spoken dialog system, a variety of adaptations have been applied to overcome some problems caused by numerous errors and variations naturally produced by non-native speakers. Furthermore, a number of methods have been developed for generating educational feedback that help learners develop to be proficient. Integrating these efforts resulted in intelligent educational robots — Mero and Engkey — and virtual 3D language learning games, Pomy. To verify the effects of our approaches on students' communicative abilities, we have conducted a field study at an elementary school in Korea. The results showed that our CALL approaches can be enjoyable and fruitful activities for students. Although the results of this study bring us a step closer to understanding computer-based education, more studies are needed to consolidate the findings.

  14. Matrix completion by deep matrix factorization.

    Fan, Jicong; Cheng, Jieyu

    2018-02-01

    Conventional methods of matrix completion are linear methods that are not effective in handling data of nonlinear structures. Recently a few researchers attempted to incorporate nonlinear techniques into matrix completion but there still exists considerable limitations. In this paper, a novel method called deep matrix factorization (DMF) is proposed for nonlinear matrix completion. Different from conventional matrix completion methods that are based on linear latent variable models, DMF is on the basis of a nonlinear latent variable model. DMF is formulated as a deep-structure neural network, in which the inputs are the low-dimensional unknown latent variables and the outputs are the partially observed variables. In DMF, the inputs and the parameters of the multilayer neural network are simultaneously optimized to minimize the reconstruction errors for the observed entries. Then the missing entries can be readily recovered by propagating the latent variables to the output layer. DMF is compared with state-of-the-art methods of linear and nonlinear matrix completion in the tasks of toy matrix completion, image inpainting and collaborative filtering. The experimental results verify that DMF is able to provide higher matrix completion accuracy than existing methods do and DMF is applicable to large matrices. Copyright © 2017 Elsevier Ltd.

    Baer, Paul; Kammen, Daniel M.

    2009-06-01

    This is not the usual Editor-in-Chief letter, namely one that focuses on the accomplishments of the journal—and for ERL they have been numerous this year—but a recognition of the critical time that we are now in when it comes to addressing not only global climate change, but also the dialog between science and politics. In recognition of the many 'tipping points' that we now confront—ideally some of them positive social moments—as well as the clear scientific conclusion that environmental tipping points are points of long-lasting disruption, this paper takes a different form than I might have otherwise written. While the scientific body of knowledge around global environmental change mounts, so too, do the hopeful signs that change can happen. The election of Barack Obama is unquestionably one such sign, witnessed by the exceptional interest that his story has brought not only to US politics, but also to global views of the potential of the United States, as well as to the potential role of science and investigation in addressing pressing issues. In light of these inter-related issues, reproduced here—largely due to the efforts of Paul Baer to transcribe a remarkable conversation—is a dialog not only on the science of global warming and the potential set of means to address this issue, but also on the interaction between research, science and the political process. The dialog itself is sufficiently important that I will dispense with the usual discussion of the exciting recognition that ERL has received with an ISI rating (a factor rapidly increasing), the high levels of downloads of our papers (for some articles over 5000 and counting), and the many news and scientific publications picking up ERL articles (in recent days alone Science, Environmental Science and Technology, and The Economist). This conversation was the concluding plenary session of the 10-12 March International Association of Research Universities (IARU) Conference on Climate Change

    2017-07-01

    Understanding that conditions of health are dependent on more general nationwide factors relating to the level of development means admitting that 'sectorization' of health service is something that tends to limit the formation of knowledge. It also points to the importance of investigating the relationship between health and development, including issues about the processes that feed the persistence of the polarization between modernization and exclusion which has been a history of Brazil's contemporary development. This paper, based on a review of the literature, aims to look more deeply at the structural conditioning factors of the relationship between health and development, and their reproduction in the formation of contemporary knowledge, based on a dialog with the ideas of Celso Furtado. It concludes that a 'virtuous' articulation between health and development calls for policies that are able to reconcile the antagonistic factors represented by the interests of capitalism, and the interests of social wellbeing, in a harmonious co-existence. In Furtado's conception, this would be possible, if the process of social homogenization is correlated with an efficient production system that has a degree of technological autonomy.

    The purpose of this articl is to explore nursing students' experiences of dialogic group oral exams used in the assessment of a medical nursing course. We discuss a small-group, educator-facilitated exam (dialogue exam). The data were gathered in April 2015 via an online survey including open questions. The participants were nursing students (n = 58) at a University of Applied Sciences. The data were subjected to inductive content analysis. The results suggest that students' experiences of the dialogue exam can be represented by four themes: context bound dynamics, new shared understanding, verified competences and holistic nursing care. The students liked the dialogue exam format, preferring it to the traditional individual written exam. The prerequisite for successful use of the dialogue exam format is that candidates perceived the exam situation as safe. Students need to be given information about the schedule and assessment criteria beforehand and should have some experience of the format. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Mother's milk is the primary source of nourishment in early infancy. When this source is unavailable, secondary sources may be used, such as human milk banks. The first milk bank in Brazil was created in 1943, and they have been used ever since. A national model was developed through a number of phases, culminating in the Brazilian Network of Human Milk Banks. This gave rise to a number of international cooperation projects, with the Brazilian model particularly relevant for developing nations. The main objective of this analysis is to understand what drives Brazil to promote milk banks internationally. To do this we tried to understand the relationship between health and foreign policy, expressed here as soft power, as here the two areas dialog with one another. The results include gains in both areas and the affirmation of health as a central goal of the national interest cluster of the case.

  2. The Amnesiac Lookback Option: Selectively Monitored Lookback Options and Cryptocurrencies

    Directory of Open Access Journals (Sweden)

    Ho-Chun Herbert Chang

    2018-05-01

    Full Text Available This study proposes a strategy to make the lookback option cheaper and more practical, and suggests the use of its properties to reduce risk exposure in cryptocurrency markets through blockchain enforced smart contracts and correct for informational inefficiencies surrounding prices and volatility. This paper generalizes partial, discretely-monitored lookback options that dilute premiums by selecting a subset of specified periods to determine payoff, which we call amnesiac lookback options. Prior literature on discretely-monitored lookback options considers the number of periods and assumes equidistant lookback periods in pricing partial lookback options. This study by contrast considers random sampling of lookback periods and compares resulting payoff of the call, put and spread options under floating and fixed strikes. Amnesiac lookbacks are priced with Monte Carlo simulations of Gaussian random walks under equidistant and random periods. Results are compared to analytic and binomial pricing models for the same derivatives. Simulations show diminishing marginal increases to the fair price as the number of selected periods is increased. The returns correspond to a Hill curve whose parameters are set by interest rate and volatility. We demonstrate over-pricing under equidistant monitoring assumptions with error increasing as the lookback periods decrease. An example of a direct implication for event trading is when shock is forecasted but its timing uncertain, equidistant sampling produces a lower error on the true maximum than random choice. We conclude that the instrument provides an ideal space for investors to balance their risk, and as a prime candidate to hedge extreme volatility. We discuss the application of the amnesiac lookback option and path-dependent options to cryptocurrencies and blockchain commodities in the context of smart contracts.

    The present leading option for plutonium disposition, either civilian or weapons Pu, is to burn it in LWRs after having converted it to MOX fuel. However, among the possible types of fuel which can be envisaged to burn plutonium in LWRs, innovative U-free fuels such as inert matrix and thoria fuel are novel concept in view of a more effective and ultimate solution from both security and safety standpoint. Inert matrix fuel is an non-fertile oxide fuel consisting of PuO 2 , either weapon-grade or reactor-grade, diluted in inert oxides such as for ex. stabilized ZrO 2 or MgAl 2 O 4 , its primary advantage consisting in no-production of new plutonium during irradiation, because it does not contain uranium (U-free fuel) whose U-238 isotope is the departure nuclide for breeding Pu-239. Some thoria addition in the matrix (thoria-doped fuel) may be required for coping with reactivity feedback needs. The full thoria-plutonia fuel though still a U-free variant cannot be defined non-fertile any more because the U-233 generation. The advantage of such a fuel option consisting basically on a remarkable already existing technological background and a potential acceleration in getting rid of the Pu stocks. All U-free fuels are envisaged to be operated under a once-through cycle scheme being the spent fuel outlooked to be sent directly to the final disposal in deep geological formations without requiring any further reprocessing treatment, thanks to the quality-poor residual Pu and a very high chemical stability under the current fuel reprocessing techniques. Besides, inert matrix-thoria fuel technology is suitable for in-reactor MAs transmutation. An additional interest in Th containing fuel refers to applicability in ADS, the innovative accelerated driven subcritical systems, specifically aimed at plutonium, minor actnides and long lived fission products transmutation in a Th-fuel cycle scheme which enables to avoid generations of new TRUs.

    Full Text Available Reducing the risk is and always will be one of the main concerns for the management of a company. One way of reducing the risk can be diversification strategy. This concept is used very commonly in almost all areas of expertise. In terms of small companies, business diversification implies development of new products and services through their own efforts, expanding the area of action, as well as the formation of strategic alliances and licensing technologies. The article is based on a theoretical approach of the Ansoff matrix, which is one of the most important tools in strategic planning in order to diversify risks. The strategic options on which the Ansoff matrix is based are: the sale of existing products on existing markets, the development and renewal of existing products on new markets, the development and renewal of new products on existing markets, the development of new products on new markets. The purpose of this article is to present and describe the Ansoff matrix as a means to reduce the risks in the development of new products on emerging markets. This strategy of diversification has into consideration linking with the capacity the company achieve realistic goals. The results that will result from this research will facilitate the analysis and the assimilaton of the information related to the Ansoff matrix, and through the general methods of scientific investigation, namely the observation, synthesis, qualitative analysis and exemplification, I will try to offer an extension of the theoretical and practical knowledge on the Ansoff Matrix.

    Full Text Available Mobile phones and related gadgets in networks are omnipresent at our students, advertising itself as the platform for mobile, pervasive learning. Currently, these devices rapidly open and enhance, being soon able to serve as a major platform for rich, open multimedia applications and communication. In this report we introduce a video conferencing software, which seamlessly integrates mobile with stationary users into fully distributed multi-party conversations. Following the paradigm of flexible, user-initiated group communication, we present an integrated solution, which scales well for medium-size conferences and accounts for the heterogeneous nature of mobile and stationary participants. This approach allows for a spontaneous, location independent establishment of video dialogs, which is of particular importance in interactive learning scenarios. The work is based on a highly optimized realization of a H.264 codec.

    Full Text Available We address the numerical solution of Lyapunov, algebraic and differential Riccati equations, via the matrix sign function, on platforms equipped with general-purpose multicore processors and, optionally, one or more graphics processing units (GPUs. In particular, we review the solvers for these equations, as well as the underlying methods, analyze their concurrency and scalability and provide details on their parallel implementation. Our experimental results show that this class of hardware provides sufficient computational power to tackle large-scale problems, which only a few years ago would have required a cluster of computers.

  7. The option to expand a project: its assessment with the binomial options pricing model

    Directory of Open Access Journals (Sweden)

    Salvador Cruz Rambaud

    Full Text Available Traditional methods of investment appraisal, like the Net Present Value, are not able to include the value of the operational flexibility of the project. In this paper, real options, and more specifically the option to expand, are assumed to be included in the project information in addition to the expected cash flows. Thus, to calculate the total value of the project, we are going to apply the methodology of the Net Present Value to the different scenarios derived from the existence of the real option to expand. Taking into account the analogy between real and financial options, the value of including an option to expand is explored by using the binomial options pricing model. In this way, estimating the value of the option to expand is a tool which facilitates the control of the uncertainty element implicit in the project.

    Smaldino, Paul E; Richerson, Peter J

    2012-01-01

    Most research on decision making has focused on how human or animal decision makers choose between two or more options, posed in advance by the researchers. The mechanisms by which options are generated for most decisions, however, are not well understood. Models of sequential search have examined the trade-off between continued exploration and choosing one's current best option, but still cannot explain the processes by which new options are generated. We argue that understanding the origins of options is a crucial but untapped area for decision making research. We explore a number of factors which influence the generation of options, which fall broadly into two categories: psycho-biological and socio-cultural. The former category includes factors such as perceptual biases and associative memory networks. The latter category relies on the incredible human capacity for culture and social learning, which doubtless shape not only our choices but the options available for choice. Our intention is to start a discussion that brings us closer toward understanding the origins of options.

    Full Text Available In this article, I explore pathways towards critical reflexivity as a way of understanding the interaction between personal and professional development. How much do we, and can we, put our personal lives into our work? Reflexivity can be developed through various methods but is explored herein through life stories and dialogical poetry as ways of deepening the connection between personal discourses and professional lives. A heuristic inquiry framework developed by Clark MOUSTAKAS is used together with poetry and dialogue to map a personal exploration of reflexivity through life story work. The journey follows six phases: initial engagement, immersion, incubation, illumination, explication, and culmination in a creative synthesis. Acknowledging that reflexivity is viewed as occurring in context, a narrative lens is used to integrate the importance of working with lived experience while recognizing how we are influenced by our past and present social interaction with others. In this way, as researchers and professionals, we are better able to position ourselves, to better understand the context in which we work, and to develop a more ethical lens through which we view our reality. The scope for personal agency and the creation of voice is explored through these interactions. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs170192

  14. Communicative action: the Habermasian and Freirean dialogical approach to participatory communication for social change in a post-1994 South Africa

    Directory of Open Access Journals (Sweden)

    2009-07-01

    Full Text Available Despite its almost four decade mainstay, the field of parti-cipatory communication for social change still experiences a definitional and pragmatic problem regarding what exactly participation is (cf. Jacobson & Storey, 2004; Chambers, 1994; Melkote & Steeves, 2001; Rogers, 1976; Lerner, 1964; Schramm, 1964; Servaes, 1995. What remains is a vastly under-theorised field of participatory communication for social change. This article examines the possibility of participatory communication approaching the Habermasian “ideal speech situation” in which people, as communicators, are seen as having a value in their own right and not simply regarded as a means to an end (cf. Habermas, 1984; 1987; 1989. Consistent with the Freirean “liberal pedagogy”, the praxis of dialogical communication or intersubjective communication is seen as putting right the “participative” quality of participatory com-munication (cf. Freire, 1970. For both theorists, transformative action can only occur if reflective and collective learning occurs in linguistically constructed settings where the normative dimensions of truth (logos, rightfulness (ethos and truthfulness (pathos are raised and met in the developmental conversation. This is especially significant in a globalised world and fragmented, post-bourgeois public sphere where debate among developmental stakeholders is becoming more marginal, in-strumentalist, and less public. Based on available analyses of development communication literature, this article proposes that the chosen dialogical approaches share a type of communi-cative behaviour (i.e. action theoretic, rather than representing a particular paradigm or school of thought. This could offer further definitional clarification of proper participatory communi-cation for social change in a post-1994 South Africa.

    This paper is discussing the role of conceptualization in political psychology and the limits that the notion of culture imposes: is it possible to construct "useful" theoretical models that offer new perspectives? What is their scope and possibility for generalization? I suggest a dialogical model of lay thinking that is grounded on a longitudinal study (from 2000 to 2010) regarding the social representation of Greek Youth for democracy (Magioglou 2008; 2013).

    Full Text Available In this short paper, we study the asymptotics for the price of call options for very large strikes and put options for very small strikes. The stock price is assumed to follow the Black–Scholes models. We analyze European, Asian, American, Parisian and perpetual options and conclude that the tail asymptotics for these option types fall into four scenarios.

  17. Feasibility and outcome of dialogical exposure therapy for posttraumatic stress disorder: a pilot study with 25 outpatients.

    2014-01-01

    The research on psychotherapy for posttraumatic stress disorder (PTSD) stems predominantly from a cognitive-behavioral orientation while other approaches are underrepresented. We evaluated dialogical exposure in trauma therapy (DET), a treatment for PTSD combining cognitive-behavioral elements with an interpersonal, gestalt-based framework. In this uncontrolled pilot trial, 25 PTSD patients were treated with DET in an outpatient setting and 21 completed therapy. There was a significant reduction in self-rated PTSD symptoms from pre- to posttreatment. Effect sizes were large in the completer sample and moderate to large in the intent-to-treat sample. General psychopathology also decreased significantly. The dropout rate was rather low at 16%. These results show that further research on DET as a treatment for PTSD is warranted.

  18. Heston Model Calibration in the Brazilian Foreign Exchange (FX Options Market

    Directory of Open Access Journals (Sweden)

    Joe Akira Yoshino

    2004-06-01

    Full Text Available Despite the relatively recent advance in the derivative industry, the European FX option market uses simple models such as Black (1976 or Garman and Kohlhagen (1983. This widespread practice hides very important quantitative effects that could be better explored by using alternative pricing models such as the one that incorporates the stochastic volatility features. Understanding and calibrating this type of pricing model represents a challenge in the current state of art in financial engineering, specially in emerging markets that are characterized by strong volatilities, periodic changing regimes and in most case suffering of liquidity, specially during the crisis. In this sense, this paper shows how to implement the Hestons Model for the Brazilian FX option market. This approach uses the volatility matrix provided by a pool of domestic market players. Although the Hestons Model presents a formal analytical solution it does not require simulation-, the closed form solutions show a mathematical complexity. Thus, the main objective of this work is to implement this model in the Brazilian FX market.

    1989-06-01

    In 1980 the multilevel multichannel R-matrix code SAMMY was released for use in analysis of neutron data at the Oak Ridge Electron Linear Accelerator. Since that time, SAMMY has undergone significant modifications: user-friendly options have been incorporated to streamline common operations and to protect a run from common user errors; the Reich-Moore formalism has been extended to include an optional logarithmic parameterization of the external R-matrix, for which any or all parameters may be varied; the ability to vary sample thickness, effective temperature, matching radius, and/or resolution-broadening parameters has been incorporated; to avoid loss of information (i.e., computer round-off errors) between runs, the ''covariance file'' now includes precise values for all variables; and unused but correlated variables may be included in the analysis. Because of these and earlier changes, the 1980 SAMMY manual is now hopelessly obsolete. This report is intended to be complete documentation for the current version of SAMMY. Its publication in looseleaf form will permit updates to the manual to be made concurrently with updates to the code itself, thus eliminating most of the time lag between update and documentation. 28 refs., 54 tabs

  1. Documentation for the “XT3D” option in the Node Property Flow (NPF) Package of MODFLOW 6

    Science.gov (United States)

    Provost, Alden M.; Langevin, Christian D.; Hughes, Joseph D.

    2017-08-10

    This report describes the “XT3D” option in the Node Property Flow (NPF) Package of MODFLOW 6. The XT3D option extends the capabilities of MODFLOW by enabling simulation of fully three-dimensional anisotropy on regular or irregular grids in a way that properly takes into account the full, three-dimensional conductivity tensor. It can also improve the accuracy of groundwater-flow simulations in cases in which the model grid violates certain geometric requirements. Three example problems demonstrate the use of the XT3D option to simulate groundwater flow on irregular grids and through three-dimensional porous media with anisotropic hydraulic conductivity.Conceptually, the XT3D method of estimating flow between two MODFLOW 6 model cells can be viewed in terms of three main mathematical steps: construction of head-gradient estimates by interpolation; construction of fluid-flux estimates by application of the full, three-dimensional form of Darcy’s Law, in which the conductivity tensor can be heterogeneous and anisotropic; and construction of the flow expression by enforcement of continuity of flow across the cell interface. The resulting XT3D flow expression, which relates the flow across the cell interface to the values of heads computed at neighboring nodes, is the sum of terms in which conductance-like coefficients multiply head differences, as in the conductance-based flow expression the NPF Package uses by default. However, the XT3D flow expression contains terms that involve “neighbors of neighbors” of the two cells for which the flow is being calculated. These additional terms have no analog in the conductance-based formulation. When assembled into matrix form, the XT3D formulation results in a larger stencil than the conductance-based formulation; that is, each row of the coefficient matrix generally contains more nonzero elements. The “RHS” suboption can be used to avoid expanding the stencil by placing the additional terms on the right-hand side

  3. Polish Toxic Currency Options

    Directory of Open Access Journals (Sweden)

    Waldemar Gontarski

    2009-06-01

    Full Text Available Toxic currency options are defined on the basis of the opposition to the nature (essence of an option contract, which is justified in terms of norms founded on the general law clause of characteristics (nature of a relation (which represents an independent premise for imposing restrictions on the freedom of contracts. So-understood toxic currency options are unlawful. Indeed they contravene iuris cogentis regulations. These include for instance option contracts, which are concluded with a bank, if the bank has not informed about option risk before concluding the contract; or the barrier options, which focus only on the protection of bank’s interests. Therefore, such options may appear to be invalid. Therefore, performing contracts for toxic currency options may be qualified as a criminal mismanagement. For the sake of security, the manager should then take into consideration filing a claim for stating invalidity (which can be made in a court verdict. At the same time, if the supervisory board member in a commercial company, who can also be a subject to mismanagement offences, commits an omission involving lack of reaction (for example, if he/she fails to notify of the suspected offence committed by the management board members acting to the company’s detriment when the management board makes the company conclude option contracts which are charged with absolute invalidity the supervisory board member so acting may be considered to act to the company’s detriment. In the most recent Polish jurisprudence and judicature the standard of a “good host” is treated to be the last resort for determining whether the manager’s powers resulting from criminal regulations were performed. The manager of the exporter should not, as a rule, issue any options. Issuing options always means assuming an obligation. In the case of currency put options it is an absolute obligation to purchase a given amount in euro at exchange rate set in advance. On the

  4. Extending the range of real time density matrix renormalization group simulations

    Science.gov (United States)

    Kennes, D. M.; Karrasch, C.

    2016-03-01

    We discuss a few simple modifications to time-dependent density matrix renormalization group (DMRG) algorithms which allow to access larger time scales. We specifically aim at beginners and present practical aspects of how to implement these modifications within any standard matrix product state (MPS) based formulation of the method. Most importantly, we show how to 'combine' the Schrödinger and Heisenberg time evolutions of arbitrary pure states | ψ 〉 and operators A in the evaluation of 〈A〉ψ(t) = 〈 ψ | A(t) | ψ 〉 . This includes quantum quenches. The generalization to (non-)thermal mixed state dynamics 〈A〉ρ(t) =Tr [ ρA(t) ] induced by an initial density matrix ρ is straightforward. In the context of linear response (ground state or finite temperature T > 0) correlation functions, one can extend the simulation time by a factor of two by 'exploiting time translation invariance', which is efficiently implementable within MPS DMRG. We present a simple analytic argument for why a recently-introduced disentangler succeeds in reducing the effort of time-dependent simulations at T > 0. Finally, we advocate the python programming language as an elegant option for beginners to set up a DMRG code.

    2007-05-15

    This thesis considers uncertainty on the long term generation expansion planning in the Brazilian Electric System, under a Real Options Approach . First, Real Options Theory is used to demonstrate the importance of thermo power plants insertion in Brazil, through a flexibility valuation on hydrothermal system. This is the first objective of this thesis. In the second part a Real Options Model is proposed to support long term expansion studies, based in a levelized costs analysis. The adequacy of proposed models to real problem is illustrated by a case study of the Brazilian Power System. The results show the importance of the energetic matrix diversification on the Long Term Planning. In the expansion model proposed, results are in favor of higher participation of biomass, nuclear power and coal in Brazilian electricity generation matrix. (author)

  6. Surgical options for lumbosacral fusion: biomechanical stability, advantage, disadvantage and affecting factors in selecting options.

    Science.gov (United States)

    Yoshihara, Hiroyuki

    2014-07-01

    Numerous surgical procedures and instrumentation techniques for lumbosacral fusion (LSF) have been developed. This is probably because of its high mechanical demand and unique anatomy. Surgical options include anterior column support (ACS) and posterior stabilization procedures. Biomechanical studies have been performed to verify the stability of those options. The options have their own advantage but also disadvantage aspects. This review article reports the surgical options for lumbosacral fusion, their biomechanical stability, advantages/disadvantages, and affecting factors in option selection. Review of literature. LSF has lots of options both for ACS and posterior stabilization procedures. Combination of posterior stabilization procedures is an option. Furthermore, combinations of ACS and posterior stabilization procedures are other options. It is difficult to make a recommendation or treatment algorithm of LSF from the current literature. However, it is important to know all aspects of the options and decision-making of surgical options for LSF needs to be tailored for each patient, considering factors such as biomechanical stress and osteoporosis.

    2009-01-01

    Since this report was originally issued in 2001, several options proposed for increasing double-shell tank (DST) storage space were implemented or are in the process of implementation. Changes to the single-shell tank (SST) waste retrieval schedule, completion of DST space saving options, and the DST space saving options in progress have delayed the projected shortfall of DST storage space from the 2007-2011 to the 2018-2025 timeframe (ORP-11242, River Protection Project System Plan). This report reevaluates options from Rev. 0 and includes evaluations of new options for alleviating projected restrictions on SST waste retrieval beginning in 2018 because of the lack of DST storage space.

    2016-07-01

    Current descriptions of the ab initio density matrix renormalization group (DMRG) algorithm use two superficially different languages: an older language of the renormalization group and renormalized operators, and a more recent language of matrix product states and matrix product operators. The same algorithm can appear dramatically different when written in the two different vocabularies. In this work, we carefully describe the translation between the two languages in several contexts. First, we describe how to efficiently implement the ab initio DMRG sweep using a matrix product operator based code, and the equivalence to the original renormalized operator implementation. Next we describe how to implement the general matrix product operator/matrix product state algebra within a pure renormalized operator-based DMRG code. Finally, we discuss two improvements of the ab initio DMRG sweep algorithm motivated by matrix product operator language: Hamiltonian compression, and a sum over operators representation that allows for perfect computational parallelism. The connections and correspondences described here serve to link the future developments with the past and are important in the efficient implementation of continuing advances in ab initio DMRG and related algorithms.

    Salvador Cruz Rambaud

    2016-01-01

    Full Text Available Usually, traditional methods for investment project appraisal such as the net present value (hereinafter NPV do not incorporate in their values the operational flexibility offered by including a real option included in the project. In this paper, real options, and more specifically the option to abandon, are analysed as a complement to cash flow sequence which quantifies the project. In this way, by considering the existing analogy with financial options, a mathematical expression is derived by using the binomial options pricing model. This methodology provides the value of the option to abandon the project within one, two, and in general n periods. Therefore, this paper aims to be a useful tool in determining the value of the option to abandon according to its residual value, thus making easier the control of the uncertainty element within the project.

    This chapter surveys the methods available for extracting information from option prices that can be used in forecasting. We consider option-implied volatilities, skewness, kurtosis, and densities. More generally, we discuss how any forecasting object that is a twice differentiable function...... of the future realization of the underlying risky asset price can utilize option-implied information in a well-defined manner. Going beyond the univariate option-implied density, we also consider results on option-implied covariance, correlation and beta forecasting, as well as the use of option......-implied information in cross-sectional forecasting of equity returns. We discuss how option-implied information can be adjusted for risk premia to remove biases in forecasting regressions....

  12. Option price and market instability

    Science.gov (United States)

    Baaquie, Belal E.; Yu, Miao

    2017-04-01

    An option pricing formula, for which the price of an option depends on both the value of the underlying security as well as the velocity of the security, has been proposed in Baaquie and Yang (2014). The FX (foreign exchange) options price was empirically studied in Baaquie et al., (2014), and it was found that the model in general provides an excellent fit for all strike prices with a fixed model parameters-unlike the Black-Scholes option price Hull and White (1987) that requires the empirically determined implied volatility surface to fit the option data. The option price proposed in Baaquie and Cao Yang (2014) did not fit the data during the crisis of 2007-2008. We make a hypothesis that the failure of the option price to fit data is an indication of the market's large deviation from its near equilibrium behavior due to the market's instability. Furthermore, our indicator of market's instability is shown to be more accurate than the option's observed volatility. The market prices of the FX option for various currencies are studied in the light of our hypothesis.

    The Options Study has been conducted for the purpose of evaluating the potential of alternative integrated nuclear fuel cycle options to favorably address the issues associated with a continuing or expanding use of nuclear power in the United States. The study produced information that can be used to inform decisions identifying potential directions for research and development on such fuel cycle options. An integrated nuclear fuel cycle option is defined in this study as including all aspects of the entire nuclear fuel cycle, from obtaining natural resources for fuel to the ultimate disposal of used nuclear fuel (UNF) or radioactive wastes. Issues such as nuclear waste management, especially the increasing inventory of used nuclear fuel, the current uncertainty about used fuel disposal, and the risk of nuclear weapons proliferation have contributed to the reluctance to expand the use of nuclear power, even though it is recognized that nuclear power is a safe and reliable method of producing electricity. In this Options Study, current, evolutionary, and revolutionary nuclear energy options were all considered, including the use of uranium and thorium, and both once-through and recycle approaches. Available information has been collected and reviewed in order to evaluate the ability of an option to clearly address the challenges associated with the current implementation and potential expansion of commercial nuclear power in the United States. This Options Study is a comprehensive consideration and review of fuel cycle and technology options, including those for disposal, and is not constrained by any limitations that may be imposed by economics, technical maturity, past policy, or speculated future conditions. This Phase II report is intended to be used in conjunction with the Phase I report, and much information in that report is not repeated here, although some information has been updated to reflect recent developments. The focus in this Options Study was to

    This work will approach the bio diesel development as renewable source fuel in the Brazilian energetic matrix. Essentially, the utilization flexibility will be considered between the traditional petroleum origin Diesel and the vegetable origin Biodiesel. So, our target is the evaluation of the flexibility existent between those two fuels. A consideration will be made via real options, where the fuel choice for supplying is modelled as a an european options sequence. Those switch input real options attributes a value to the project and minimizes the risks associated to the energy offer shortage which is another recurrent problem inside our reality. At least, some comments will be made on the potential gain on the aggregate value for the Brazil, as a consequence of Diesel dependent road transportation.

  15. Efficient Trajectory Options Allocation for the Collaborative Trajectory Options Program

    Rodionova, Olga; Arneson, Heather; Sridhar, Banavar; Evans, Antony

    2017-01-01

    The Collaborative Trajectory Options Program (CTOP) is a Traffic Management Initiative (TMI) intended to control the air traffic flow rates at multiple specified Flow Constrained Areas (FCAs), where demand exceeds capacity. CTOP allows flight operators to submit the desired Trajectory Options Set (TOS) for each affected flight with associated Relative Trajectory Cost (RTC) for each option. CTOP then creates a feasible schedule that complies with capacity constraints by assigning affected flights with routes and departure delays in such a way as to minimize the total cost while maintaining equity across flight operators. The current version of CTOP implements a Ration-by-Schedule (RBS) scheme, which assigns the best available options to flights based on a First-Scheduled-First-Served heuristic. In the present study, an alternative flight scheduling approach is developed based on linear optimization. Results suggest that such an approach can significantly reduce flight delays, in the deterministic case, while maintaining equity as defined using a Max-Min fairness scheme.

    2010-09-01

    Full Text Available The importance of galleries as go-betweens for artists and art buyers is acknowl-edged in art world research. Using a Bakhtinian dialogic approach, this article examines social encounters of three artists, two art buyers and one gallery sales executive in Singapore. Specifically, it looks into the social interactional dynam-ics of artists and art buyers when they trade directly. Situational ambiguities and emotional ambivalence arise during such meetings from the different expectations and demands that are imposed, which have the effect of placing the parties in-volved in conflicting social contexts. For instance, when art connoisseurs and art-ists discuss aesthetics, monetary value is not of primary concern, nonetheless when they want to trade, commercial concerns become central; this can lead to discomfort between the parties. Similarly, art buyers may want to go behind the scenes to know more about the artist and the art practice; getting away from the glitter of the commercial gallery and into the modest art studio for an authentic experience may reveal too much for visitors; such experiences may break their illusion of the glamorous artist. This article looks at the microscopic interaction between artists and art buyers and shows how the ambiguities and ambivalence that can be generated by their encounters become constraining factors in encour-aging artists and art buyers to trade directly, by-passing commercial art galleries and dealers.

    There is a distance between the power that whole class dialogic discussions (WCDD) may offer to the science class and their use in practice. Teachers' attitudes toward WCDD are part of the problem. The aims of this study were twofold: (a) to examine Taiwanese physics teachers' attitudes toward WCDD by considering cultural perspectives and describe how these attitudes changed as a result of a special workshop designed for this purpose, and (b) to report on how these attitudes should be taken into account in designing such workshops in the future. Nine experienced physics teachers participated in the WCDD workshop. The workshop was based on the WCDD model developed by Eshach (2010). Inductive analyses were performed on interviews with the teachers and their students, which were composed of 36 questions and developed specially for the purpose of this study, yielded the following categories: (1) In-school reasons for opposing WCDD—reasons belonging to school ways/tradition of teaching that may cause barriers to WCDD implementation; (2) External Factors—cultural reasons relating to Taiwanese views concerning education in general, which cause barriers to WCDD implementation; and (3) Cognitive aspect—refers to what teachers know about WCDD. The paper concludes with a discussion on what should be done in order to successfully bring WCDD to the Taiwanese physics class.

    This study performs a cost and schedule analysis of three Nevada Transportation options that support waste receipt at the repository. Based on the U.S. Department of Energy preference for rail transportation in Nevada (given in the Final Environmental Impact Statement), it has been assumed that a branch rail line would be constructed to support waste receipt at the repository. However, due to potential funding constraints, it is uncertain when rail will be available. The three Nevada Transportation options have been developed to meet a varying degree of requirements for transportation and to provide cost variations used in meeting the funding constraints given in the Technical Direction Letter guidelines for this study. The options include combinations of legal-weight truck, heavy-haul truck, and rail. Option 1 uses a branch rail line that would support initial waste receipt at the repository in 2010. Rail transportation would be the primary mode, supplemented by legal weight trucks. This option provides the highest level of confidence in cost and schedule, lowest public visibility, greatest public acceptability, lowest public dose, and is the recommended option for support of waste receipt. The completion of rail by 2010 will require spending approximately $800 million prior to 2010. Option 2 uses a phased rail approach to address a constrained funding scenario. To meet funding constraints, Option 2 uses a phased approach to delay high cost activities (final design and construction) until after initial waste receipt in 2010. By doing this, approximately 95 percent of the cost associated with completion of a branch rail line is deferred until after 2010. To support waste receipt until a branch rail line is constructed in Nevada, additional legal-weight truck shipments and heavy-haul truck shipments (on a limited basis for naval spent nuclear fuel) would be used to meet the same initial waste receipt rates as in Option 1. Use of heavy-haul shipments in the absence

    The use of stock options for executive compensation has become a lightning rod for public anger, and it's easy to see why. Many top executives grew hugely rich on the back of the gains they made on their options, profits they've been able to keep even as the value they were supposed to create disappeared. The supposed scam works like this: Current accounting regulations let companies ignore the cost of option grants on their income statements, so they can award valuable option packages without affecting reported earnings. Not charging the cost of the grants supposedly leads to overstated earnings, which purportedly translate into unrealistically high share prices, permitting top executives to realize big gains when they exercise their options. If an accounting anomaly is the problem, then the solution seems obvious: Write off executive share options against the current year's revenues. The trouble is, Sahlman writes, expensing option grants won't give us a more accurate view of earnings, won't add any information not already included in the financial statements, and won't even lead to equal treatment of different forms of executive pay. Far worse, expensing evades the real issue, which is whether compensation (options and other-wise) does what it's supposed to do--namely, help a company recruit, retain, and provide the right people with appropriate performance incentives. Any performance-based compensation system has the potential to encourage cheating. Only ethical management, sensible governance, adequate internal control systems, and comprehensive disclosure will save the investor from disaster. If, Sahlman warns, we pass laws that require the expensing of options, thinking that's fixed the fundamental flaws in corporate America's accounting, we will have missed a golden opportunity to focus on the much more extensive defects in the present system.

  2. NDMA formation from amine-based pharmaceuticals--impact from prechlorination and water matrix.

    Science.gov (United States)

    Shen, Ruqiao; Andrews, Susan A

    2013-05-01

    The presence of N-nitrosodimethylamine (NDMA) in drinking water is most commonly associated with the chloramination of amine-based precursors. One option to control the NDMA formation is to remove the precursors via pre-oxidation, and prechlorination is among the most effective options in reducing NDMA formation. However, most of the findings to-date are based on single-precursor scenarios using the model precursor dimethylamine (DMA) and natural organic matter (NOM), while few studies have considered the potential interactions between water matrix components and the target precursors when investigating the prechlorination impact. Specifically, little is known for the behaviour of amine-based pharmaceuticals which have recently been reported to contribute to NDMA formation upon chloramination. This work demonstrates that prechlorination can affect both the ultimate NDMA conversion and the reaction kinetics from selected pharmaceuticals, and the nature and extent of the impact was compound-specific and matrix-specific. In the absence of NOM, the NDMA formation from most pharmaceuticals was reduced upon prechlorination, except for sumatriptan which showed a consistent increase in NDMA formation with increasing free chlorine contact time. In the presence of NOM, prechlorination was shown to enhance initial reactions by reducing the binding between NOM and pharmaceuticals, but prolonged prechlorination broke down NOM into smaller products which could then form new bonds with pharmaceuticals and thus inhibit their further conversion into NDMA.

  3. An SPSSR -Menu for Ordinal Factor Analysis

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Exploratory factor analysis is a widely used statistical technique in the social sciences. It attempts to identify underlying factors that explain the pattern of correlations within a set of observed variables. A statistical software package is needed to perform the calculations. However, there are some limitations with popular statistical software packages, like SPSS. The R programming language is a free software package for statistical and graphical computing. It offers many packages written by contributors from all over the world and programming resources that allow it to overcome the dialog limitations of SPSS. This paper offers an SPSS dialog written in theR programming language with the help of some packages, so that researchers with little or no knowledge in programming, or those who are accustomed to making their calculations based on statistical dialogs, have more options when applying factor analysis to their data and hence can adopt a better approach when dealing with ordinal, Likert-type data.

  4. Understanding community and solidarity tourism: a dialog with experiences in Marraquech and Latin America

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available Discussion on community tourism and solidarity tourism reflects on others such as: cultural tourism, ethnic tourism, ecotourism and rural tourism, many times expropriated by darwinean logics and capitalist dynamics which limit tourist experiences potentialities to the conservation of traditional ways of life. This article intends to dialog with commercial exchange ceremonies experienced in Marraquech in Dezember 2008 to understand community and solidarity tourism in Latin America. Tourism in Marraquech is divided through a wall. Inside it, at the Medina, socio cultural beriberi and Arabian culture is predominant, under the only commercial ceremonial: you never know if you are doing big deal. Outside, west prone socio-cultural circuit is predominant, with hotel chains, restaurants and international shops known as the more expensive, the best! Reflection is made about the way ceremonies, turned into ways of life are similar or not. No doubt real wall is not as big as the symbolic wall between villages: western and communitarian, and between tourisms, conventional and solidarity local based one.

  8. 2005 resource options report

    International Nuclear Information System (INIS)

    Morris, T.

    2005-01-01

    This resource options report (ROR) fulfils regulatory requirements in British Columbia's two-year resource planning process. It identifies a wide range of resources and technologies that could be used to meet BC Hydro's future electricity demand. As such, it facilitates a transparent public review of resource options which include both supply-side and demand-side options. The resource options that will be used in the 2005 integrated electricity plan (IEP) were characterized. This ROR also documents where there is a general agreement or disagreement on the resource type characterization, based on the First Nations and Stakeholder engagement. BC Hydro used current information to provide realistic ranges on volume and cost to characterize environmental and social attributes. The BC Hydro system was modelled to assess the benefit and cost of various resource options. The information resulting from this ROR and IEP will help in making decisions on how to structure competitive acquisition calls and to determine the level of transmission services needed to advance certain BC Hydro projects. The IEP forecasts the nature and quantity of domestic resources required over the next 20 years. A strategic direction on how those needs will be met has been created to guide the management of BC Hydro's energy resources. Supply-side options include near-commercial technologies such as energy storage, ocean waves, tidal, fuel cells and integrated coal gasification combined cycle technology. Supply-side options also include natural gas, coal, biomass, geothermal, wind, and hydro. 120 refs., 39 tabs., 21 figs., 6 appendices

  10. Dopamine Modulates Option Generation for Behavior.

    2018-05-21

    Animals make innumerable decisions every day, each of which involves evaluating potential options for action. But how are options generated? Although much is now known about decision making when a fixed set of potential options is provided, surprisingly little progress has been made on self-generated options. Some researchers have proposed that such abilities might be modulated by dopamine. Here, we used a new measure of option generation that is quantitative, objective, and culture fair to investigate how humans generate different behavioral options. Participants were asked to draw as many different paths (options) as they could between two points within a fixed time. Healthy individuals (n = 96) exhibited a trade-off between uniqueness (how individually different their options were) and fluency (number of options), generating either many similar or few unique options. To assess influence of dopamine, we first examined patients with Parkinson's disease (n = 35) ON and OFF their dopaminergic medication and compared them to elderly healthy controls (n = 34). Then we conducted a double-blind, placebo-controlled crossover study of the D2 agonist cabergoline in healthy older people (n = 29). Across both studies, dopamine increased fluency but diminished overall uniqueness of options generated, due to the effect of fluency trading off with uniqueness. Crucially, however, when this trade-off was corrected for, dopamine was found to increase uniqueness for any given fluency. Three carefully designed control studies showed that performance on our option-generation task was not related to executing movements, planning actions, or selecting between generated options. These findings show that dopamine plays an important role in modulating option generation. Copyright © 2018 The Author(s). Published by Elsevier Ltd.. All rights reserved.

  15. COGEMA gives communication a new impetus: transparency to conduct a new dialog

    International Nuclear Information System (INIS)

    Graffin, K.

    2000-01-01

    COGEMA launched in November 1999 a mass public communication campaign and created an Internet site equipped with cameras (web-cams) to make everyone familiar with the COGEMA plant at La Hague. This system is designed to serve as a communication policy that is resolutely open and attentive to French public concerns. The campaign includes TV commercials and press ads. The underlying principle is to work on issues that have made the news. The televised system includes two films shot at La Hague. The first, lasting 90 seconds, consists of interviews and testimonies of employees who represent the professional and human diversity of the plant. The second, in 45-second format, presents the questions to which public opinion wants answers. To ensure that everyone obtains all the answers to their questions, the TV spots and press ads refer to the web-site: www.cogemalahague.fr. Cybemauts can witness live, by means of a dozen web-cams, what actually happens in different places at COGEMA La Hague: general view of the site, spent fuel unloading installations, storage ponds, Valognes rail terminal, etc. The gist of this first step in the new dialog that COGEMA wants to establish with public opinion is to get beyond irrational fears through transparency, and to show that COGEMA's men and women are fully responsible and determined to contribute actively to the information of the public at large.

  20. SAMMY, Multilevel R-Matrix Fits to Neutron and Charged-Particle Cross-Section Data Using Bayes' Equations

    International Nuclear Information System (INIS)

    Larson, Nancy M.

    2007-01-01

    1 - Description of problem or function: The purpose of the code is to analyze time-of-flight cross section data in the resolved and unresolved resonance regions, where the incident particle is either a neutron or a charged particle (p, alpha, d,...). Energy-differential cross sections and angular-distribution data are treated, as are certain forms of energy-integrated data. In the resolved resonance region (RRR), theoretical cross sections are generated using the Reich-Moore approximation to R-matrix theory (and extensions thereof). Sophisticated models are used to describe the experimental situation: Data-reduction parameters (e.g. normalization, background, sample thickness) are included. Several options are available for both resolution and Doppler broadening, including a crystal-lattice model for Doppler broadening. Self-shielding and multiple-scattering correction options are available for analysis of capture cross sections. Multiple isotopes and impurities within a sample are handled accurately. Cross sections in the unresolved resonance region (URR) can also be analyzed using SAMMY. The capability was borrowed from Froehner's FITACS code; SAMMY modifications for the URR include more exact calculation of partial derivatives, normalization options for the experimental data, increased flexibility for input of experimental data, introduction of user-friendly input options. In both energy regions, values for resonance parameters and for data-related parameters (such as normalization, sample thickness, effective temperature, resolution parameters) are determined via fits to the experimental data using Bayes' method (see below). Final results may be reported in ENDF format for inclusion in the evaluated nuclear data files. The manner in which SAMMY 7 (released in 2006) differs from the previous version (SAMMY-M6) is itemized in Section I.A of the SAMMY users' manual. Details of the 7.0.1 update are documented in an errata SAMMY 7.0.1 Errata (http

  3. M(atrix) theory: matrix quantum mechanics as a fundamental theory

    International Nuclear Information System (INIS)

    Taylor, Washington

    2001-01-01

    This article reviews the matrix model of M theory. M theory is an 11-dimensional quantum theory of gravity that is believed to underlie all superstring theories. M theory is currently the most plausible candidate for a theory of fundamental physics which reconciles gravity and quantum field theory in a realistic fashion. Evidence for M theory is still only circumstantial -- no complete background-independent formulation of the theory exists as yet. Matrix theory was first developed as a regularized theory of a supersymmetric quantum membrane. More recently, it has appeared in a different guise as the discrete light-cone quantization of M theory in flat space. These two approaches to matrix theory are described in detail and compared. It is shown that matrix theory is a well-defined quantum theory that reduces to a supersymmetric theory of gravity at low energies. Although its fundamental degrees of freedom are essentially pointlike, higher-dimensional fluctuating objects (branes) arise through the non-Abelian structure of the matrix degrees of freedom. The problem of formulating matrix theory in a general space-time background is discussed, and the connections between matrix theory and other related models are reviewed

We start from methods used for basket options and Asian options. First, we use the general approach for deriving upper and lower bounds for stop-loss premia of sums of non-independent random variables as in Kaas et al. [Upper and lower bounds for sums of random variables, Insurance Math. Econom. 27 (2000) 151-168] or Dhaene et al. [The concept of comonotonicity in actuarial science and finance: theory, Insurance Math. Econom. 31(1) (2002) 3-33]. We generalize the methods in Deelstra et al. [Pricing of arithmetic basket options by conditioning, Insurance Math. Econom. 34 (2004) 55-57] and Vanmaele et al. [Bounds for the price of discrete sampled arithmetic Asian options, J. Comput. Appl. Math. 185(1) (2006) 51-90]. Afterwards we show how to derive an analytical closed-form expression for a lower bound in the non-comonotonic case. Finally, we derive upper bounds for Asian basket options by applying techniques as in Thompson [Fast narrow bounds on the value of Asian options, Working Paper, University of Cambridge, 1999] and Lord [Partially exact and bounded approximations for arithmetic Asian options, J. Comput. Finance 10 (2) (2006) 1-52]. Numerical results are included and on the basis of our numerical tests, we explain which method we recommend depending on moneyness and time-to-maturity.

  11. OPTION(5) versus OPTION(12) instruments to appreciate the extent to which healthcare providers involve patients in decision-making.

    Science.gov (United States)

    Stubenrouch, Fabienne E; Pieterse, Arwen H; Falkenberg, Rijan; Santema, T Katrien B; Stiggelbout, Anne M; van der Weijden, Trudy; Aarts, J Annemijn W M; Ubbink, Dirk T

    2016-06-01

    The 12-item "observing patient involvement" (OPTION(12))-instrument is commonly used to assess the extent to which healthcare providers involve patients in health-related decision-making. The five-item version (OPTION(5)) claims to be a more efficient measure. In this study we compared the Dutch versions of the OPTION-instruments in terms of inter-rater agreement and correlation in outpatient doctor-patient consultations in various settings, to learn if we can safely switch to the shorter OPTION(5)-instrument. Two raters coded 60 audiotaped vascular surgery and oncology patient consultations using OPTION(12) and OPTION(5). Unweighted Cohen's kappa was used to compute inter-rater agreement on item-level. The association between the total scores of the two OPTION-instruments was investigated using Pearson's correlation coefficient (r) and a Bland & Altman plot. After fine-tuning the OPTION-manuals, inter-rater agreement for OPTION(12) and OPTION(5) was good to excellent (kappa range 0.69-0.85 and 0.63-0.72, respectively). Mean total scores were 23.7 (OPTION(12); SD=7.8) and 39.3 (OPTION(5); SD=12.7). Correlation between the total scores was high (r=0.71; p=0.01). OPTION(5) scored systematically higher with a wider range than OPTION(12). Both OPTION-instruments had a good inter-rater agreement and correlated well. OPTION(5) seems to differentiate better between various levels of patient involvement. The OPTION(5)-instrument is recommended for clinical application. Copyright © 2015 Elsevier Ireland Ltd.

  15. FTR-option formulation and pricing

    International Nuclear Information System (INIS)

    Parmeshwaran, Vijay; Muthuraman, Kumar

    2009-01-01

    Recent changes in electricity markets have advocated the use of Local Marginal Prices (LMP) for congestion management and pricing. From the perspective of market participants, the LMPs pose a risk since they are not known before a transaction on the grid is made. Financial transmission rights (FTR) are instruments that help market participants hedge this risk and are issuable in two flavors - obligations and options. While pricing obligations are much easier, pricing FTR options pose a significant challenge. In this paper we develop a computational method for pricing FTR options. We also discuss the problem of designing financial instrument sets that assure revenue adequacy for the issuer. We point out the difficulty in assuring revenue adequacy when FTR options are present and propose a scheme for overcoming the difficulty. The proposed pricing method can be used to compute prices of options and obligations in the primary market or as a reliable pricing tool to compute option prices in the secondary market. Finally using a test network we present and discuss numerical results. (author)

  16. Platelet-rich plasma and chronic wounds: remaining fibronectin may influence matrix remodeling and regeneration success.

    Science.gov (United States)

    Moroz, Andrei; Deffune, Elenice

    2013-11-01

    Platelet-rich plasma has been largely used as a therapeutic option for the treatment of chronic wounds of different etiologies. The enhanced regeneration observed after the use of platelet-rich plasma has been systematically attributed to the growth factors that are present inside platelets' granules. We hypothesize that the remaining plasma and platelet-bound fibronectin may act as a further bioactive protein in platelet-rich plasma preparations. Recent reports were analyzed and presented as direct evidences of this hypotheses. Fibronectin may directly influence the extracellular matrix remodeling during wound repair. This effect is probably through matrix metalloproteinase expression, thus exerting an extra effect on chronic wound regeneration. Physicians should be well aware of the possible fibronectin-induced effects in their future endeavors with PRP in chronic wound treatment. Copyright © 2013 International Society for Cellular Therapy.

  18. Floating matrix tablets based on low density foam powder: effects of formulation and processing parameters on drug release.

    Science.gov (United States)

    Streubel, A; Siepmann, J; Bodmeier, R

    2003-01-01

    The aim of this study was to develop and physicochemically characterize single unit, floating controlled drug delivery systems consisting of (i). polypropylene foam powder, (ii). matrix-forming polymer(s), (iii). drug, and (iv). filler (optional). The highly porous foam powder provided low density and, thus, excellent in vitro floating behavior of the tablets. All foam powder-containing tablets remained floating for at least 8 h in 0.1 N HCl at 37 degrees C. Different types of matrix-forming polymers were studied: hydroxypropyl methylcellulose (HPMC), polyacrylates, sodium alginate, corn starch, carrageenan, gum guar and gum arabic. The tablets eroded upon contact with the release medium, and the relative importance of drug diffusion, polymer swelling and tablet erosion for the resulting release patterns varied significantly with the type of matrix former. The release rate could effectively be modified by varying the "matrix-forming polymer/foam powder" ratio, the initial drug loading, the tablet geometry (radius and height), the type of matrix-forming polymer, the use of polymer blends and the addition of water-soluble or water-insoluble fillers (such as lactose or microcrystalline cellulose). The floating behavior of the low density drug delivery systems could successfully be combined with accurate control of the drug release patterns.

  5. Fuzzy vulnerability matrix

    International Nuclear Information System (INIS)

    Baron, Jorge H.; Rivera, S.S.

    2000-01-01

    The so-called vulnerability matrix is used in the evaluation part of the probabilistic safety assessment for a nuclear power plant, during the containment event trees calculations. This matrix is established from what is knows as Numerical Categories for Engineering Judgement. This matrix is usually established with numerical values obtained with traditional arithmetic using the set theory. The representation of this matrix with fuzzy numbers is much more adequate, due to the fact that the Numerical Categories for Engineering Judgement are better represented with linguistic variables, such as 'highly probable', 'probable', 'impossible', etc. In the present paper a methodology to obtain a Fuzzy Vulnerability Matrix is presented, starting from the recommendations on the Numerical Categories for Engineering Judgement.

    A systematic construction of the Green's matrix for a second-order self-adjoint matrix differential operator from the linearly independent solutions of the corresponding homogeneous differential equation set is carried out. We follow the general approach of extracting the Green's matrix from the Green's matrix of the corresponding first-order system. This construction is required in the cases where the differential equation set cannot be turned to an algebraic equation set via transform techniques.

    Binding to the extracellular matrix, one of the most abundant human protein complexes, significantly affects drug disposition. Specifically, the interactions with extracellular matrix determine the free concentrations of small molecules acting in tissues, including signaling peptides, inhibitors of tissue remodeling enzymes such as matrix metalloproteinases, and other drug candidates. The nature of extracellular matrix binding was elucidated for 63 matrix metalloproteinase inhibitors, for which the association constants to an extracellular matrix mimic were reported here. The data did not correlate with lipophilicity as a common determinant of structure-nonspecific, orientation-averaged binding. A hypothetical structure of the binding site of the solidified extracellular matrix surrogate was analyzed using the Comparative Molecular Field Analysis, which needed to be applied in our multi-mode variant. This fact indicates that the compounds bind to extracellular matrix in multiple modes, which cannot be considered as completely orientation-averaged and exhibit structural dependence. The novel comparative molecular field analysis models, exhibiting satisfactory descriptive and predictive abilities, are suitable for prediction of the extracellular matrix binding for the untested chemicals, which are within applicability domains. The results contribute to a better prediction of the pharmacokinetic parameters such as the distribution volume and the tissue-blood partition coefficients, in addition to a more imminent benefit for the development of more effective matrix metalloproteinase inhibitors.

    Vaginal microbicides for the prevention of HIV transmission may be an important option for protecting women from infection. Incorporation of dapivirine, a lead candidate nonnucleoside reverse transcriptase inhibitor, into intravaginal rings (IVRs) for sustained mucosal delivery may increase microbicide product adherence and efficacy compared with conventional vaginal formulations. Twenty-four healthy HIV-negative women 18-35 years of age were randomly assigned (1:1:1) to dapivirine matrix IVR, dapivirine reservoir IVR, or placebo IVR. Dapivirine concentrations were measured in plasma and vaginal fluid samples collected at sequential time points over the 33-day study period (28 days of IVR use, 5 days of follow-up). Safety was assessed by pelvic/colposcopic examinations, clinical laboratory tests, and adverse events. Both IVR types were safe and well tolerated with similar adverse events observed in the placebo and dapivirine groups. Dapivirine from both IVR types was successfully distributed throughout the lower genital tract at concentrations over 4 logs greater than the EC50 against wild-type HIV-1 (LAI) in MT4 cells. Maximum concentration (Cmax) and area under the concentration-time curve (AUC) values were significantly higher with the matrix than reservoir IVR. Mean plasma concentrations of dapivirine were <2 ng/mL. These findings suggest that IVR delivery of microbicides is a viable option meriting further study.

  9. Option Derivatives in Electricity Hedging

    2010-01-01

    Full Text Available Despite the high volatility of electricity prices, there is still little demand for electricity power options, and the liquidity on the power exchanges of these power derivatives is quite low. One of the reasons is the uncertainty about how to evaluate these electricity options and about finding the right fair value of this product. Hedging of electricity is associated mainly with products such as futures and forwards. However, due to new trends in electricity trading and hedging, it is also useful to think more about options and the principles for working with them in hedging various portfolio positions and counterparties. We can quite often encounter a situation when we need to have a perfect hedge for our customer’s (end user consuming electricity portfolio, or we have to evaluate the volumetric risk (inability of a customer to predict consumption, which is very similar to selling options. Now comes the moment to compare the effects of using options or futures to hedge these open positions. From a practical viewpoint, the Black-Scholes prices appear to be the best available and the simplest method for evaluating option premiums, but there are some limitations that we have to consider.

  12. Neutrino mass matrix

    International Nuclear Information System (INIS)

    Strobel, E.L.

    1985-01-01

    Given the many conflicting experimental results, examination is made of the neutrino mass matrix in order to determine possible masses and mixings. It is assumed that the Dirac mass matrix for the electron, muon, and tau neutrinos is similar in form to those of the quarks and charged leptons, and that the smallness of the observed neutrino masses results from the Gell-Mann-Ramond-Slansky mechanism. Analysis of masses and mixings for the neutrinos is performed using general structures for the Majorana mass matrix. It is shown that if certain tentative experimental results concerning the neutrino masses and mixing angles are confirmed, significant limitations may be placed on the Majorana mass matrix. The most satisfactory simple assumption concerning the Majorana mass matrix is that it is approximately proportional to the Dirac mass matrix. A very recent experimental neutrino mass result and its implications are discussed. Some general properties of matrices with structure similar to the Dirac mass matrices are discussed

    Chang, Bo-Young; Christoffersen, Peter; Vainberg, Gregory

    2012-01-01

    Equity risk measured by beta is of great interest to both academics and practitioners. Existing estimates of beta use historical returns. Many studies have found option-implied volatility to be a strong predictor of future realized volatility. We find that option-implied volatility and skewness...... are also good predictors of future realized beta. Motivated by this finding, we establish a set of assumptions needed to construct a beta estimate from option-implied return moments using equity and index options. This beta can be computed using only option data on a single day. It is therefore potentially...

The interaction of mutual relationships is believed to produce energy, and thereby promote structural evolution and subject emancipation. This initiated relationship and interaction is represents the concept of dialogic action proposed in Freire’s theory.

    2009-01-01

    Electrochemical method with salt as electrolyte has been studied to disintegrate the graphite matrix from the simulative high temperature gas-cooled reactor fuel elements. Ammonium nitrate was experimentally chosen as the appropriate electrolyte. The volume average diameter of disintegrated graphite fragments is about 100 μm and the maximal value is less than 900 μm. After disintegration, the weight of graphite is found to increase by about 20% without the release of a large amount of CO 2 probably owing to the partial oxidation to graphite in electrochemical process. The present work indicates that the improved electrochemical method has the potential to reduce the secondary nuclear waste and is a promising option to disintegrate graphite matrix from high temperature gas-cooled reactor spent fuel elements in the head-end of reprocessing.

  20. Comparing future options for human space flight

    Sherwood, Brent

    2011-09-01

    The paper analyzes the "value proposition" for government-funded human space flight, a vexing question that persistently dogs efforts to justify its $10 10/year expense in the US. The original Mercury/Gemini/Apollo value proposition is not valid today. Neither was it the value proposition actually promoted by von Braun, which the post-Apollo 80% of human space flight history has persistently attempted to fulfill. Divergent potential objectives for human space flight are captured in four strategic options— Explore Mars; accelerate Space Passenger Travel; enable Space Power for Earth; and Settle the Moon—which are then analyzed for their purpose, societal myth, legacy benefits, core needs, and result as measured by the number and type of humans they would fly in space. This simple framework is proposed as a way to support productive dialog with public and other stakeholders, to determine a sustainable value proposition for human space flight.

    2018-01-01

    Full Text Available Early into his career as one of the most successful printerpublishers of the Dutch Republic, Elie Luzac (1721-1796 played a pivotal role in disseminating the materialist ideas of La Mettrie’s Homme machine (1747. This paper focuses on the dialogic voice (Bakhtine in a publication by Luzac himself, which oscillates between asserting and refuting La Mettrie’s views. Descended from Huguenot refugees, Luzac condemns what he publishes and publishes what he condemns. This discursive ambiguity emerges in Luzac’s L’homme plus que machine (1748, a work which cites La Mettrie’s theses in order to contest them. Building on the succès de scandale of the English version of L’homme machine (Man a Machine, 1749, the English translation of L’homme plus que machine, Man more than a Machine, appeared in 1752. The present contribution examines how the translator’s Voice, which is defined as an enarrative voice, effaces the concealed claims of the original text and replaces them with a discourse whose explicit anti-materialist tenor contrasts with the vehement rhetoric of Man a Machine.

    International Nuclear Information System (INIS)

    Markowski, Adam S.; Mannan, M. Sam

    2008-01-01

    A risk matrix is a mechanism to characterize and rank process risks that are typically identified through one or more multifunctional reviews (e.g., process hazard analysis, audits, or incident investigation). This paper describes a procedure for developing a fuzzy risk matrix that may be used for emerging fuzzy logic applications in different safety analyses (e.g., LOPA). The fuzzification of frequency and severity of the consequences of the incident scenario are described which are basic inputs for fuzzy risk matrix. Subsequently using different design of risk matrix, fuzzy rules are established enabling the development of fuzzy risk matrices. Three types of fuzzy risk matrix have been developed (low-cost, standard, and high-cost), and using a distillation column case study, the effect of the design on final defuzzified risk index is demonstrated

    Science.gov (United States)

    Jones, Jenny; Strube, Petra; Mitchell, Marion; Henderson, Amanda

    2017-01-01

    Compassion, understood as empathy for another who is experiencing physical, mental, emotional and/or spiritual suffering, is an essential element of our shared understandings of nursing and the constitution of the professional nurse. Theoretical foundation: Charles Taylor account of ethics which concerns 'what or who is it good to be' rather than the predominant analytical moral philosophy approach which concentrates on 'what ought one to do' is the core concern of this discussion. An ontological appreciation of our shared human condition is the premise upon which the discussion is based. This article proposes that concept by opening a dialogical space, nurses can engage in reflection and sense making wherein they explore individually and collectively the conflicts and confusions encountered in their day-to-day work. Through their dialogues, nurses - individually and collectively - orient and reorient themselves and each other towards what they see as meaningful and purposeful in their lives and in doing so they are well positioned to reaffirm their commitment to compassion as a value which both anchors and orients their day-to-day work. The provision of opportunities in the workplace, in the form of dialogue, to articulate often unspoken assumptions and frameworks in which nursing work is carried out can not only initiate the building of pathways of support but also assist nurses reaffirm their compassion - arguably the essence of their nursing practice.

  10. Molecular dynamics simulations of matrix assisted laser desorption ionization: Matrix-analyte interactions

    International Nuclear Information System (INIS)

    Nangia, Shivangi; Garrison, Barbara J.

    2011-01-01

    There is synergy between matrix assisted laser desorption ionization (MALDI) experiments and molecular dynamics (MD) simulations. To understand analyte ejection from the matrix, MD simulations have been employed. Prior calculations show that the ejected analyte molecules remain solvated by the matrix molecules in the ablated plume. In contrast, the experimental data show free analyte ions. The main idea of this work is that analyte molecule ejection may depend on the microscopic details of analyte interaction with the matrix. Intermolecular matrix-analyte interactions have been studied by focusing on 2,5-dihydroxybenzoic acid (DHB; matrix) and amino acids (AA; analyte) using Chemistry at HARvard Molecular Mechanics (CHARMM) force field. A series of AA molecules have been studied to analyze the DHB-AA interaction. A relative scale of AA molecule affinity towards DHB has been developed.

  15. Trauma, dream, and psychic change in psychoanalyses: a dialog between psychoanalysis and the neurosciences

    2013-01-01

    To many psychoanalysts dreams are a central source of knowledge of the unconscious—the specific research object of psychoanalysis. The dialog with the neurosciences, devoted to the testing of hypotheses on human behavior and neurophysiology with objective methods, has added to psychoanalytic conceptualizations on emotion, memory, sleep and dreams, conflict and trauma. To psychoanalysts as well as neuroscientists, the neurological basis of psychic functioning, particularly concerning trauma, is of special interest. In this article, an attempt is made to bridge the gap between psychoanalytic findings and neuroscientific findings on trauma. We then attempt to merge both approaches in one experimental study devoted to the investigation of the neurophysiological changes (fMRI) associated with psychoanalytic treatment in chronically depressed patients. We also report on an attempt to quantify psychoanalysis-induced transformation in the manifest content of dreams. To do so, we used two independent methods. First, dreams reported during the cure of chronic depressed analysands were assessed by the treating psychoanalyst. Second, dreams reported in an experimental context were analyzed by an independent evaluator using a standardized method to quantify changes in dream content (Moser method). Single cases are presented. Preliminary results suggest that psychoanalysis-induced transformation can be assessed in an objective way. PMID:24381554

  20. American option pricing with stochastic volatility processes

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available In order to solve the problem of option pricing more perfectly, the option pricing problem with Heston stochastic volatility model is considered. The optimal implementation boundary of American option and the conditions for its early execution are analyzed and discussed. In view of the fact that there is no analytical American option pricing formula, through the space discretization parameters, the stochastic partial differential equation satisfied by American options with Heston stochastic volatility is transformed into the corresponding differential equations, and then using high order compact finite difference method, numerical solutions are obtained for the option price. The numerical experiments are carried out to verify the theoretical results and simulation. The two kinds of optimal exercise boundaries under the conditions of the constant volatility and the stochastic volatility are compared, and the results show that the optimal exercise boundary also has stochastic volatility. Under the setting of parameters, the behavior and the nature of volatility are analyzed, the volatility curve is simulated, the calculation results of high order compact difference method are compared, and the numerical option solution is obtained, so that the method is verified. The research result provides reference for solving the problems of option pricing under stochastic volatility such as multiple underlying asset option pricing and barrier option pricing.

    Highlights: ► Proton transfer and adduction reaction of matrix in MALDI were studied. ► Hydroxyl group forming intramolecular hydrogen bond was related to the ionization. ► Intramolecular proton transfer in the electronic excited state was the initial step. ► Non-volatile analytes stabilized protonated matrix in the ground state. ► A possible mechanism, “analyte support mechanism”, has been proposed. - Abstract: Proton transfer and adduction reaction of matrix molecules in matrix-assisted laser desorption ionization were studied. By using 2,4,6-trihydroxyacetophenone (THAP), 2,5-dihydroxybenzoic acid (DHBA), and their related compounds in which the position of a hydroxyl group is different, it was clarified that a hydroxyl group forming an intramolecular hydrogen bond is related to the ionization of matrix molecules. Intramolecular proton transfer in the electronic excited state of the matrix and subsequent proton adduction from a surrounding solvent to the charge-separated matrix are the initial steps for the ionization of matrix molecules. Nanosecond pump–probe NIR–UV mass spectrometry confirmed that the existence of analyte molecules having large dipole moment in their structures is necessary for the stabilization of [matrix + H]{sup +} in the electronic ground state.

    A risk-based priority for the retrieval of Hanford Site waste from the 149 single-shell tanks (SSTs) has been adopted as a result of changes to the Hanford Federal Facility Agreement and Consent Order (HFFACO) (Ecology et al. 1997) negotiated in 2000. Retrieval of the first three tanks in the retrieval sequence fills available capacity in the double-shell tanks (DSTs) by 2007. As a result, the HFFACO change established a milestone (M-45-12-TO1) requiring the determination of options that could increase waste storage capacity for single-shell tank waste retrieval. The information will be considered in future negotiations. This document fulfills the milestone requirement. This study presents options that were reviewed for the purpose of increasing waste storage capacity. Eight options are identified that have the potential for increasing capacity from 5 to 10 million gallons, thus allowing uninterrupted single-shell tank retrieval until the planned Waste Treatment Plant begins processing substantial volumes of waste from the double-shell tanks in 2009. The cost of implementing these options is estimated to range from less than $1 per gallon to more than $14 per gallon. Construction of new double-shell tanks is estimated to cost about $63 per gallon. Providing 5 to 10 million gallons of available double-shell tank space could enable early retrieval of 5 to 9 high-risk single-shell tanks beyond those identified for retrieval by 2007. These tanks are A-101, AX-101, AX-103, BY-102, C-107, S-105, S-106, S-108, and S-109 (Garfield et al. 2000). This represents a potential to retrieve approximately 14 million total curies, including 3,200 curies of long-lived mobile radionuclides. The results of the study reflect qualitative analyses conducted to identify promising options. The estimated costs are rough-order-of magnitude and, therefore, subject to change. Implementing some of the options would represent a departure from the current baseline and may adversely impact the

    Sparse Matrix-Matrix multiplication is a key kernel that has applications in several domains such as scienti c computing and graph analysis. Several algorithms have been studied in the past for this foundational kernel. In this paper, we develop parallel algorithms for sparse matrix-matrix multiplication with a focus on performance portability across different high performance computing architectures. The performance of these algorithms depend on the data structures used in them. We compare different types of accumulators in these algorithms and demonstrate the performance difference between these data structures. Furthermore, we develop a meta-algorithm, kkSpGEMM, to choose the right algorithm and data structure based on the characteristics of the problem. We show performance comparisons on three architectures and demonstrate the need for the community to develop two phase sparse matrix-matrix multiplication implementations for efficient reuse of the data structures involved.
