  3. Experts' Views Regarding the Conceptualization of Narcissism. (United States)

    Ackerman, Robert A; Hands, Aaron J; Donnellan, M Brent; Hopwood, Christopher J; Witt, Edward A


    There is debate over the definition of narcissism across social/personality and clinical psychology. The current article aims to quantify the level of disagreement by measuring experts' opinions concerning the attributes most central to narcissism. Accordingly, we developed a comprehensive list of attributes associated with narcissism and had 49 self-identified experts (among them 17 women, 23 psychologists from clinical psychology and 22 from social/personality psychology) rate these characteristics and provide their opinions on several issues related to the conceptualization of narcissism. Experts generally believe that the grandiose features of narcissism are more central than the vulnerable features. However, differences between clinical and social/personality psychologists were evident, especially regarding the relevance of self-esteem. Given the results, we suggest that researchers specify the kind of narcissism being assessed in a given study and consider using assessments of the full range of narcissistic features in future research to provide a more comprehensive perspective on the construct.

    Many governments believe that investing in human capital should increase citizens' employability, which is why it is often presented as a solution to the problems of knowledge-based economies and societies, rising unemployment rates and economic competiveness. The aim of this study is to understand employers' views regarding the employability of…

  6. A narrow view: The conceptualization of sexual problems in human sexuality textbooks. (United States)

    Stelzl, Monika; Stairs, Brittany; Anstey, Hannah


    This study examined the ways in which the meaning of 'sexual problems' is constructed and defined in undergraduate human sexuality textbooks. Drawing on feminist and critical discourse frameworks, the dominant as well as the absent/marginalized discourses were identified using critical discourse analysis. Sexual difficulties were largely framed by the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. Thus, medical discourse was privileged. Alternative conceptualizations and frameworks, such as the New View of Women's Sexual Problems, were included marginally and peripherally. We argue that current constructions of sexuality knowledge reinforce, rather than challenge, existing hegemonic discourses of sexuality.

  8. Toward a richer view of the scientific method. The role of conceptual analysis. (United States)

    Machado, Armando; Silva, Francisco J


    Within the complex set of activities that comprise the scientific method, three clusters of activities can be recognized: experimentation, mathematization, and conceptual analysis. In psychology, the first two of these clusters are well-known and valued, but the third seems less known and valued. The authors show the value of these three clusters of scientific method activities in the works of the quintessential scientist Galileo Galilei. They then illustrate how conceptual analysis can be used in psychology to clarify the grammar and meaning of concepts, expose conceptual problems in models, reveal unacknowledged assumptions and steps in arguments, and evaluate the consistency of theoretical accounts. The article concludes with a discussion of three criticisms of conceptual analysis. Copyright 2007 APA, all rights reserved.

  12. Figures of speech, signs of knowing: Towards a semiotic view of science conceptualization (United States)

    Wizinowich, Janice Ingrid

    Models for science education, rather than paralleling the process of scientific discovery, have traditionally involved the dissemination of information through texts and controlled lab experiences. These have had limited effect in the development of science concepts. Therefore, the focus of this study was to investigate alternative avenues, such as the use of narrative, for science conceptualization. Despite the potential for narrative as an avenue for science conceptualization, for the most part studies involving literature have not explored this relationship. The purpose of this study was to investigate the process of science conceptualization, with a specific focus on narrative. This was done through a fifth grade classroom based study where learning experiences were created, focused on the concept of interdependence in relationship to water. These experiences included open-ended, hands-on science experiences, literature discussion groups, self-selected research projects and the creation of narrative pieces based on those research projects. Data sources included: (a) audio and videotaped literature discussion group sessions; (b) audio and videotaped study group interviews and curricular sessions; (c) individual interviews; (d) learning log entries and reflections; and (e) student narratives. Data analysis was conducted within a semiotic theoretical framework and involved the process of retroduction. Retroduction entails a kind of spiraling dialectic between theoretical considerations and data incidences, from which are generated possible explanations. These possible explanations or abductions, provide direction for further forays into the data. The process of retroduction lends itself to the creation of data analysis chapters that highlight theoretical issues in relationship to the data or "theoretical memos". Three theoretical memos emerged from this process. Theoretical memo one explores the role of experience in conceptualization; theoretical memo two focuses

  13. Factors affecting employee turnover and sound retention strategies in business organization: a conceptual view

    Directory of Open Access Journals (Sweden)

    Chowdhury Abdullah Al Mamun


    Full Text Available “Employee turnover” as an expression is broadly used in business organization. Despite the fact that several studies have been performed on this topic, little research has been conducted on examining the causes and leading factors of turnover as well, as advising some feasible approaches, which can be applied by bosses to ensure that employees will continue in their respective organizations to enhance organizational effectiveness and productivity. The main purpose of this study is to determine the reasons and key factors in the perspectives of the relevant literature and identify to the intention of employee turnover. This conceptual paper also suggests various possible strategies on how to minimize the turnover and retain employees in the organizations. Hence, the paper has proposed a conceptual framework that shows the major variables in explaining the phenomenon of employee turnover and addressing sound retention strategies to handle these issues.

  14. Conceptual or procedural mathematics for engineering students - views of two qualified engineers from two countries (United States)

    Bergsten, Christer; Engelbrecht, Johann; Kågesten, Owe


    This study forms part of a collaboration project between universities in South Africa and Sweden in which we investigate whether the emphasis in undergraduate mathematics courses for engineering students would benefit from being more conceptually oriented than a traditional more procedurally oriented way of teaching. In this paper, we report in some detail from two interviews with professional engineers, selected to represent two different 'poles' of engineering work. The aim was to explore different kinds of arguments regarding the role of mathematics in engineering work, as well as some common across contexts. Both interviewees feel that conceptual mathematics is more important for engineering work, although the role of the procedural aspect was seen by one of the interviewees also to be important, but in a very intricate way.

  15. Virtual Learning Environments: A View from the Theory of Conceptual Fields

    Directory of Open Access Journals (Sweden)

    Iralí Araque


    Full Text Available The inclusion of communication and information technologies for formative purposes has given way to virtual learning environments, which, backed by constructivist theories, provide a theoretical and methodological framework, thus contributing to the cognitive development of students at university level, evidenced in the development of their learning schemes. The theory of conceptual fields offers an analysis of the elements of schemas and the process of knowledge construction. In this sense, the present work had as objective to raise some elements, such as teaching methodology, didactic strategies, materials and resources for learning, teacher and student roles, which should be considered in the design of virtual learning environments, in the light of the theory of conceptual fields, so as to enhance the construction of knowledge and where the emphasis of the educational process lies on learning rather than teaching. The methodology used is a documentary study, type descriptive, based on the review and bibliographical analysis of constructivist theories, as well as researchers related to the design and construction of virtual learning environments. The results show that conceptual fields theory is an excellent option to consider, as a constructivist theory, in order to consolidate the process of knowledge construction, from the individual to the collective.

  16. Gender Congruency From a Neutral Point of View: The Roles of Gender Classes and Conceptual Connotations. (United States)

    Bender, Andrea; Beller, Sieghard; Klauer, Karl Christoph


    The question of whether language affects thought is long-standing, with grammatical gender being one of the most contended instances. Empirical evidence focuses on the gender congruency effect, according to which referents of masculine nouns are conceptualized more strongly as male and those of feminine nouns more strongly as female. While some recent studies suggest that this effect is driven by conceptual connotations rather than grammatical properties, research remains theoretically inconclusive because of the confounding of grammatical gender and conceptual connotations in gendered (masculine or feminine) nouns. Taking advantage of the fact that German also includes a neuter gender, the current study attempted to disentangle the relative contributions of grammatical properties and connotations to the emergence of the gender congruency effect. In three pairs of experiments, neuter and gendered nouns were compared in an Extrinsic Affective Simon Task based on gender associations, controlled for a possible role of gender-indicating articles. A congruency effect emerged equally strongly for neuter and gendered nouns, but disappeared when including connotations as covariate, thereby effectively excluding grammatical gender as the (only) driving force for this effect. Based on a critical discussion of these findings, we propose a possible mechanism for the emergence of the effect that also has the potential to accommodate conflicting patterns of findings from previous research.

  17. Comparison of the Conceptualization of Wisdom in Ancient Indian Literature with Modern Views (United States)

    Jeste, Dilip V.; Vahia, Ipsit V.


    The study of wisdom has recently become a subject of growing scientific interest, although the concept of wisdom is ancient. This article focuses on conceptualization of wisdom in the Bhagavad Gita, arguably the most influential of all ancient Hindu philosophical/religious texts. Our review, using mixed qualitative/quantitative methodology with the help of Textalyser and NVivo software, found the following components to be associated with the concept of wisdom in the Gita: Knowledge of life, Emotional Regulation, Control over Desires, Decisiveness, Love of God, Duty and Work, Self-Contentedness, Compassion/Sacrifice, Insight/Humility, and Yoga (Integration of personality). A comparison of the conceptualization of wisdom in the Gita with that in modern scientific literature shows several similarities, such as rich knowledge about life, emotional regulation, insight, and a focus on common good (compassion). Apparent differences include an emphasis in the Gita on control over desires and renunciation of materialistic pleasures. Importantly, the Gita suggests that at least certain components of wisdom can be taught and learned. We believe that the concepts of wisdom in the Gita are relevant to modern psychiatry in helping develop psychotherapeutic interventions that could be more individualistic and more holistic than those commonly practiced today, and aimed at improving personal well-being rather than just psychiatric symptoms.

  18. Re-conceptualizing stress: Shifting views on the consequences of stress and its effects on stress reactivity (United States)

    Liu, Jenny J. W.


    Background The consequences of stress are typically regarded from a deficit-oriented approach, conceptualizing stress to be entirely negative in its outcomes. This approach is unbalanced, and may further hinder individuals from engaging in adaptive coping. In the current study, we explored whether negative views and beliefs regarding stress interacted with a stress framing manipulation (positive, neutral and negative) on measures of stress reactivity for both psychosocial and physiological stressors. Method Ninety participants were randomized into one of three framing conditions that conceptualized the experience of stress in balanced, unbalanced-negative or unbalanced-positive ways. After watching a video on stress, participants underwent a psychosocial (Trier Social Stress Test), or a physiological (CO2 challenge) method of stress-induction. Subjective and objective markers of stress were assessed. Results Most of the sampled population regarded stress as negative prior to framing. Further, subjective and objective reactivity were greater to the TSST compared to the CO2 challenge. Additionally, significant cubic trends were observed in the interactions of stress framing and stress-induction methodologies on heart rate and blood pressure. Balanced framing conditions in the TSST group had a significantly larger decrease in heart rate and diastolic blood pressure following stress compared to the positive and negative framing conditions. Conclusion Findings confirmed a deficit-orientation of stress within the sampled population. In addition, results highlighted the relative efficacy of the TSST compared to CO2 as a method of stress provocation. Finally, individuals in framing conditions that posited stress outcomes in unbalanced manners responded to stressors less efficiently. This suggests that unbalanced framing of stress may have set forth unrealistic expectations regarding stress that later hindered individuals from adaptive responses to stress. Potential

  19. Conceptualizing the curse: two views on our responsibility for the ‘resource curse’

    Directory of Open Access Journals (Sweden)

    Shmuel Nili


    Full Text Available This essay critically engages proposals by Thomas Pogge and Leif Wenar meant to combat ‘the resource curse.’ Pogge and Wenar call for boycotts against stealing oppressors, sharing the expectation that the boycotts will significantly contribute to economic and political reform in the target countries. In contrast, I argue that liberal democracies should indeed stop trading with dictators and civil warriors, but for inward rather than outward looking reasons. We, the citizens of liberal democracies through our elected governments, ought to boycott severely oppressive regimes for the sake of our own moral integrity—simply in order to stop being complicit in what is effectively massive scale armed robbery. This inward looking thesis is distinctive in three ways. First, it contrasts with the dominant assumption that global reform must be grounded in the achievement of better political and economic outcomes for others. Second, the inward look manages to avoid the profound empirical uncertainty associated with any attempt to predict the direct effects of global rule changes on domestic institutions. Third, by isolating each democracy's responsibility for each case of illicit trade, the inward looking strategy deals more adequately than the outward view with collective action problems, and therefore has a greater chance of grounding actual reforms, with whatever prospects for better outcomes they may entail.

  20. [Meanings and conceptualizations of nursing: the point of view of students from the nursing degree program at the Universidad Nacional de Lanús, 2008-2010]. (United States)

    Arakaki, Jorge


    This work looks into the meanings of nursing from the point of view of the students in an undergraduate nursing degree program. The research took place at the Universidad Nacional de Lanús using semistructured interviews - eleven individual and seven group interviews - carried out between 2008 and 2010. A content analysis was then undertaken and the most relevant meanings in relation to four themes were selected: reasons for studying nursing, what nursing is, nursing as a profession, and working in nursing. Multiple and diverse ways of defining nursing were uncovered. Utilizing some conceptual developments from the sociology of the professions, the meanings were organized into four conceptualizations that represent ways of understanding nursing: as a vocation, as a profession, with a utilitarian perspective and with a community perspective. The conclusions reached indicate the need to broaden the debate regarding the types of nurses that are being trained.

Second, we address the…

  2. Use of item response curves of the Force and Motion Conceptual Evaluation to compare Japanese and American students' views on force and motion (United States)

    Ishimoto, Michi; Davenport, Glen; Wittmann, Michael C.


    Student views of force and motion reflect the personal experiences and physics education of the student. With a different language, culture, and educational system, we expect that Japanese students' views on force and motion might be different from those of American students. The Force and Motion Conceptual Evaluation (FMCE) is an instrument used to probe student views on force and motion. It was designed using research on American students, and, as such, the items might function differently for Japanese students. Preliminary results from a translated version indicated that Japanese students had similar misconceptions as those of American students. In this study, we used item response curves (IRCs) to make more detailed item-by-item comparisons. IRCs show the functioning of individual items across all levels of performance by plotting the proportion of each response as a function of the total score. Most of the IRCs showed very similar patterns on both correct and incorrect responses; however, a few of the plots indicate differences between the populations. The similar patterns indicate that students tend to interact with FMCE items similarly, despite differences in culture, language, and education. We speculate about the possible causes for the differences in some of the IRCs. This report is intended to show how IRCs can be used as a part of the validation process when making comparisons across languages and nationalities. Differences in IRCs can help to pinpoint artifacts of translation, contextual effects because of differences in culture, and perhaps intrinsic differences in student understanding of Newtonian motion.

  3. Foreign Loans and Development in the Twentieth Century India: An Over View of Conceptual Issues and Implications


    OMPRASAD, Gadde


    Abstract. The flow of foreign loans occupies a critical position in the economic development of the developing and under developed countries. Some writers view it in terms of the “dependency theory”, which states that foreign economic assistance is a tool through which the “center” exploits the “periphery” and so, the latter continues to remain undeveloped. Here, the center is donor and the periphery is the capital-receiving country. Less income levels, resources, inherited poverty, lack of g...

  8. Transition to parenthood in the neonatal care unit: a qualitative study and conceptual model designed to illuminate parent and professional views of the impact of webcam technology. (United States)

    Kerr, Susan; King, Caroline; Hogg, Rhona; McPherson, Kerri; Hanley, Janet; Brierton, Maggie; Ainsworth, Sean


    Complications during pregnancy, childbirth and/or the postnatal period may result in the admission of a baby to a neonatal unit (NNU). While the survival and long-term prospects of high-risk infants are enhanced by admission, the enforced separation of the parent and child may have psychological consequences for both. There is a need to develop and evaluate interventions to help parents 'feel closer' to their infants in circumstances where they are physically separated from them. In this paper we present findings from an in-depth, theoretically-driven, evaluation of a technological innovation designed to address this need. The study sought to explore parent and professional views of the impact of the technology, which transmits real-time images of the baby via a webcam from the NNU to the mother's bedside in the post-natal care environment. A qualitative approach was adopted, guided by a critical realist perspective. Participants were recruited purposively from a NNU located in East-central Scotland. Thirty-three parents and 18 professionals were recruited. Data were collected during individual, paired and small group interviews and were analysed thematically. Following the initial analysis process, abductive inference was used to consider contextual factors and mechanisms of action appearing to account for reported outcomes. Views on the technology were overwhelmingly positive. It was perceived as a much needed and important advancement in care delivery. Benefits centred on: enhanced feelings of closeness and responsiveness; emotional wellbeing; physical recovery; and the involvement of family/friends. These benefits appeared to function as important mechanisms in supporting the early bonding process and wider transition to parenthood. However, for a small number of the parents, use of the technology had not enhanced their experience and it is important, as with any intervention, that professionals monitor the parents' response and act accordingly. With a current

    CERN Document Server

    Sully, Anthony


    Maximizing reader insights into interior design as a conceptual way of thinking, which is about ideas and how they are formulated. The major themes of this book are the seven concepts of planning, circulation, 3D, construction, materials, colour and lighting, which covers the entire spectrum of a designer’s activity. Analysing design concepts from the view of the range of possibilities that the designer can examine and eventually decide by choice and conclusive belief the appropriate course of action to take in forming that particular concept, the formation and implementation of these concepts is taken in this book to aid the designer in his/her professional task of completing a design proposal to the client. The purpose of this book is to prepare designers to focus on each concept independently as much as possible, whilst acknowledging relative connections without unwarranted influences unfairly dictating a conceptual bias, and is about that part of the design process called conceptual analysis. It is assu...

  6. Conceptualizing Pharmaceutical Plants

    DEFF Research Database (Denmark)

    Larsen, Bent Dalgaard; Jensen, Klaes Ladeby; Gjøl, Mikkel


    In the conceptual design phase of pharmaceutical plants as much as 80%-90% of the total cost of a project is committed. It is therefore essential that the chosen concept is viable. In this design process configuration and 3D models can help validate the decisions made. Designing 3D models...... is a complex task and requires skilled users. We demonstrate that a simple 2D/3D configuration tool can support conceptualizing of pharmaceutical plants. Present paper reports on preliminary results from a full scale implementation project at a Danish engineering company....

  7. Transgressions and boundaries of the page as conceptual art

    Directory of Open Access Journals (Sweden)

    Rita M.C. Swanepoel


    Full Text Available This article offers a philosophical overview of conceptual art. I argue that, since the project Transgressions and boundaries of the page transgresses and conceptually extends the boundaries of the concept of the book, it can be viewed in its entirety as a language-based installation art, consisting of various components, viz. artists’ books. Due to its interdisciplinary nature, this conceptual art installation challenges the boundaries of conceptual art. The project and exhibitions confirm that artists’ books constitute an ideal medium to involve artists from divergent disciplines in the play with and discovery of the possibilities of the book. The project as a whole can be categorised as conceptual art, as it reconsiders, reinvents and theorises the concept book.

  17. Is Neurolaw Conceptually Confused? (United States)

    Levy, Neil


    In Minds, Brains, and Law, Michael Pardo and Dennis Patterson argue that current attempts to use neuroscience to inform the theory and practice of law founder because they are built on confused conceptual foundations. Proponents of neurolaw attribute to the brain or to its parts psychological properties that belong only to people; this mistake vitiates many of the claims they make. Once neurolaw is placed on a sounder conceptual footing, Pardo and Patterson claim, we will see that its more dramatic claims are false or meaningless, though it might be able to provide inductive evidence for particular less dramatic claims (that a defendant may be lying, or lacks control over their behavior, for instance). In response, I argue that the central conceptual confusions identified by Pardo and Patterson are not confusions at all. Though some of the claims made by its proponents are hasty and sometimes they are confused, there are no conceptual barriers to attributing psychological properties to brain states. Neuroscience can play a role in producing evidence that is more reliable than subjective report or behavior; it therefore holds out the possibility of dramatically altering our self-conception as agents and thereby the law.

  19. Participation in Information Markets Research: A New Conceptualization and Measurement

    Directory of Open Access Journals (Sweden)

    Khalid N. Alhayyan


    Full Text Available Participation is a fundamental concept in information systems research. It has been viewed to be a promising factor for the success of any IT system. However, its complex nature with respect to its conceptualization and measurement reported mix findings to the literature. In this paper, a literature review is conducted across many research disciplines to find a solid ground for proposing definition and new measures for assessing computer-recorded (e.g. online participation. Specifically, this paper redefines traditional views on IS-related participation into a new conceptualization, and proposes methods for its operationalization to appropriately fit within recent technological contexts such as information markets.

  20. Conceptual querying through ontologies

    DEFF Research Database (Denmark)

    Andreasen, Troels; Bulskov, Henrik


    We present here ail approach to conceptual querying where the aim is, given a collection of textual database objects or documents, to target an abstraction of the entire database content in terms of the concepts appearing in documents, rather than the documents in the collection. The approach...... is motivated by an obvious need for users to survey huge volumes of objects in query answers. An ontology formalism and a special notion of-instantiated ontology" are introduced. The latter is a structure reflecting the content in the document collection in that; it is a restriction of a general world...... knowledge ontology to the concepts instantiated in the collection. The notion of ontology-based similarity is briefly described, language constructs for direct navigation and retrieval of concepts in the ontology are discussed and approaches to conceptual summarization are presented....

    In this paper, we explore the potential of using visual representations to support people in managing, organizing, and understanding relations between multiple visualization views. Multiple views can help people understand different facets of data and data processing, and are a crucial part of data...... analysis particularly when it is done collaboratively. Both the growing use of multiple views and the increasing display sizes have amplified the need to explore how to better help people to understand the relations between many views. To improve our understanding of how to visualize view relations, we...... invited visualization and interaction designers to critique and sketch representations of view relations. The participants provided design critiques, and sketched their own relation representations. Our findings expand the range and palette of ways of visually linking visualization views and suggest new...

  2. Neural Adaptation Effects in Conceptual Processing

    Directory of Open Access Journals (Sweden)

    Barbara F. M. Marino


    Full Text Available We investigated the conceptual processing of nouns referring to objects characterized by a highly typical color and orientation. We used a go/no-go task in which we asked participants to categorize each noun as referring or not to natural entities (e.g., animals after a selective adaptation of color-edge neurons in the posterior LV4 region of the visual cortex was induced by means of a McCollough effect procedure. This manipulation affected categorization: the green-vertical adaptation led to slower responses than the green-horizontal adaptation, regardless of the specific color and orientation of the to-be-categorized noun. This result suggests that the conceptual processing of natural entities may entail the activation of modality-specific neural channels with weights proportional to the reliability of the signals produced by these channels during actual perception. This finding is discussed with reference to the debate about the grounded cognition view.

    This book is a second completely revised edition of ""An Informal Introduction to Turbulence"". The main emphasis is on conceptual and problematic aspects, physical phenomena, observations, misconceptions and unresolved issues rather than on conventional formalistic aspects, models, etc. Apart from the obvious fundamental importance of turbulent flows such an emphasis is a consequence of the view that without corresponding progress in fundamental aspects there is little chance for progress in any applications such as drag reduction, mixing, control and modeling of turbulence.

  17. Collective memory: conceptual foundations and theoretical approaches. (United States)

    Wertsch, James V; Roediger, Henry L


    In order to outline the conceptual landscape that frames discussions of collective memory, three oppositions are proposed: collective memory versus collective remembering; history versus collective memory; and individual memory versus collective remembering. From this perspective collective remembering is viewed as an active process that often involves contention and contestation among people rather than a static body of knowledge that they possess. Collective remembering is also viewed as privileging identity formation and contestation over the sort of objective representation of the past that is the aspiration of formal historical analysis. And finally, while collective remembering involves individual minds, it also suggests something more in the form of socially situated individuals, a claim that can usefully be formulated in terms of how members of a groups share a common set of cultural tools (e.g., narrative forms) and similar content.

  18. Food web conceptual model (United States)

    Hartman, Rosemary; Brown, Larry R.; Hobbs, Jim


    This chapter describes a general model of food webs within tidal wetlands and represents how physical features of the wetland affect the structure and function of the food web. This conceptual model focuses on how the food web provides support for (or may reduce support for) threatened fish species. This model is part of a suite of conceptual models designed to guide monitoring of restoration sites throughout the San Francisco Estuary (SFE), but particularly within the Sacramento-San Joaquin Delta (Delta) and Suisun Marsh. The conceptual models have been developed based on the Delta Regional Ecosystem Restoration Implementation Plan (DRERIP) models, and are designed to aid in the identification and evaluation of monitoring metrics for tidal wetland restoration projects. Many tidal restoration sites in the Delta are being constructed to comply with environmental regulatory requirements associated with the operation of the Central Valley Project and State Water Project. These include the Biological Opinions for Delta Smelt (Hypomesus transpacificus) and salmonids (U.S. Fish and Wildlife Service 2008; National Marine Fisheries Service 2009), and the Incidental Take Permit for Longfin Smelt (Spirinchus thaleichthyes) (California Department of Fish and Wildlife 2009). These regulatory requirements are based on the hypothesis that the decline of listed fish species is due in part to a decline in productivity of the food web (phytoplankton and zooplankton in particular) or alterations in the food web such that production is consumed by other species in the Estuary (Sommer et al. 2007; Baxter et al. 2010; Brown et al. 2016a). Intertidal wetlands and shallow subtidal habitat can be highly productive, so restoring areas of tidal wetlands may result in a net increase in productivity that will provide food web support for these fish species. However, other factors such as invasive bivalves that reduce phytoplankton and zooplankton biomass and invasive predatory fishes that may

  20. Conceptual Combination During Sentence Comprehension (United States)

    Swinney, David; Love, Tracy; Walenski, Matthew; Smith, Edward E.


    This experiment examined the time course of integration of modifier-noun (conceptual) combinations during auditory sentence comprehension using cross-modal lexical priming. The study revealed that during ongoing comprehension, there is initial activation of features of the noun prior to activation of (emergent) features of the entire conceptual combination. These results support compositionality in conceptual combination; that is, they indicate that features of the individual words constituting a conceptual combination are activated prior to combination of the words into a new concept.

  3. Shuttle freezer conceptual design (United States)

    Proctor, B. W.; Russell, D. J.


    A conceptual design for a kit freezer for operation onboard shuttle was developed. The freezer features a self-contained unit which can be mounted in the orbiter crew compartment and is capable of storing food at launch and returning with medical samples. Packaging schemes were investigated to provide the optimum storage capacity with a minimum weight and volume penalty. Several types of refrigeration systems were evaluated to select one which would offer the most efficient performance and lowest hazard of safety to the crew. Detailed performance data on the selected, Stirling cycle principled refrigeration unit were developed to validate the feasibility of its application to this freezer. Thermal analyses were performed to determine the adequacy of the thermal insulation to maintain the desired storage temperature with the design cooling capacity. Stress analyses were made to insure the design structure integrity could be maintained over the shuttle flight regime. A proposed prototype freezer development plan is presented.

  4. Conceptualizing Embedded Configuration

    Installing and servicing complex electromechanical systems is more tedious than is necessary. By putting the product knowledge into the product itself, which then would allow automation in constructing the product from modules, could solve that. It would support personnel in aftersales installation...... and services. The general idea can be named embedded configuration. In this article we intend to conceptualize embedded configuration, what it is and is not. The difference between embedded configuration, sales configuration and embedded software is explained. We will look at what is needed to make embedded...... configuration systems. That will include requirements to product modelling techniques. An example with consumer electronics will illuminate the elements of embedded configuration in settings that most can relate to. The question of where embedded configuration would be relevant is discussed, and the current...

  5. Learner factors associated with radical conceptual change among undergraduates (United States)

    Olson, Joanne Kay

    Students frequently enter learning situations with knowledge inconsistent with scientific views. One goal of science instruction is to enable students to construct scientifically accepted ideas while rejecting inaccurate constructs. This process is called conceptual change. This study examined factors associated with students at three levels of conceptual change to elucidate possible influences on the conceptual change process. Factors studied included motivation (including utility value, interest, attainment value, mood, self efficacy, and task difficulty), prior experiences with science, perceptions of the nature of science, connections to objects or events outside the classroom, and specific activities that helped students learn. Four science classes for undergraduate preservice elementary teachers participated in the study, conducted during a three week unit on electricity. Data sources included concept maps, drawings, reflective journal entries, quizzes, a science autobiography assignment, and interviews. Concept maps, drawings, and quizzes were analyzed, and students were placed into high, moderate, and low conceptual change groups. Of the ninety-eight students in the study, fifty-seven were interviewed. Perhaps the most important finding of this study relates to the assessment of conceptual change. Interviews were conducted two months after the unit, and many items on the concept maps had decayed from students' memories. This indicates that time is an important factor. In addition, interview-derived data demonstrated conceptual change levels; concept maps were insufficient to indicate the depth of students' understanding. Factors associated with conceptual change include self efficacy and interest in topic. In addition, moderate conceptual change students cited specific activities as having helped them learn. Low and high students focused on the method of instruction rather than specific activities. Factors not found to be associated with conceptual change

    Full Text Available CONCEPTUAL DELIMITATIONS OF CONTROLLING Nedelcu Serban Universitatea ,,Babes-Bolyai`` Facultatea de Stiinte Economice si Gestiunea Afacerilor 'Controlling' represents a new concept in the Romanian economic environement, being implemented successfully in very few companies. Unlike the German space where controlling is very well represented both at a practical level and in the academia, in Romania controlling can only be found at a practical level, and the specialized literature is restraint, almost absent. Since the practicians of controlling in Romania only know the toolkit they use and not the theoretical elements as well, what is needed in this case is a conceptual delimitation so that controlling would be better implemented, and improved with various elements of the economic environment. In practice, inside various linguistic areas different problems of communication may occur very often in regards to the use of different concepts that may be missunderstood. Therefore in the Romanian research area it becomes imperative to try and clarify the existing issues and to intensify the reasearch in this field. Studying the evolution of the concept we observe that the need for its implementation is primarily experienced at the practical level of the companies, to be then followed by a debate in the specialized literature. The internationalization and the fierce competition that the Romanian companies are confronting on the ecenomic market represent the decissive factor in adopting the concept of controlling.This article is part of the research conducted for my doctoral thesis, 'Controlling in hetergenous economic envirnoments', under the coordination and supervision of Prof.Dr.Dumitru Matis.

    define conceptual designing as a constructive framing and re-framing activity, which is mediated by and targeted at the creation of new design concepts. Conceptual designing as an approach is valuable for addressing the fuzziness and ambiguity typical of research that explores novel areas with new...... partners, methods and resources. It is by no means a new phenomenon, and the main contribution of the article is the clarification of conceptual designing as a particular approach to designing and researching. The approach embraces openness, resource-construction and collaboration. We conclude...... that conceptual designing can be especially useful in research and design projects that bring different kinds of people, organizations, technologies and domains together into the forming of new well-founded proposals for development.

    Kueh Hua Ng


    Full Text Available This study aims to enhance our current understanding of the transfer of training by proposing a conceptual model that supports the mediating role of motivation to improve work through learning about the relationship between social support and the transfer of training. The examination of motivation to improve work through motivation to improve work through a learning construct offers a holistic view pertaining to a learner's profile in a workplace setting, which emphasizes learning for the improvement of work performance. The proposed conceptual model is expected to benefit human resource development theory building, as well as field practitioners by emphasizing the motivational aspects crucial for successful transfer of training.

    Energy Technology Data Exchange (ETDEWEB)



    Brookhaven National Laboratory has prepared a conceptual design for a world class user facility for scientific research using synchrotron radiation. This facility, called the ''National Synchrotron Light Source II'' (NSLS-II), will provide ultra high brightness and flux and exceptional beam stability. It will also provide advanced insertion devices, optics, detectors, and robotics, and a suite of scientific instruments designed to maximize the scientific output of the facility. Together these will enable the study of material properties and functions with a spatial resolution of {approx}1 nm, an energy resolution of {approx}0.1 meV, and the ultra high sensitivity required to perform spectroscopy on a single atom. The overall objective of the NSLS-II project is to deliver a research facility to advance fundamental science and have the capability to characterize and understand physical properties at the nanoscale, the processes by which nanomaterials can be manipulated and assembled into more complex hierarchical structures, and the new phenomena resulting from such assemblages. It will also be a user facility made available to researchers engaged in a broad spectrum of disciplines from universities, industries, and other laboratories.

  15. PHENIX Conceptual Design Report

    Energy Technology Data Exchange (ETDEWEB)

    Nagamiya, Shoji; Aronson, Samuel H.; Young, Glenn R.; Paffrath, Leo


    The PHENIX Conceptual Design Report (CDR) describes the detector design of the PHENIX experiment for Day-1 operation at the Relativistic Heavy Ion Collider (RHIC). The CDR presents the physics capabilities, technical details, cost estimate, construction schedule, funding profile, management structure, and possible upgrade paths of the PHENIX experiment. The primary goals of the PHENIX experiment are to detect the quark-gluon plasma (QGP) and to measure its properties. Many of the potential signatures for the QGP are measured as a function of a well-defined common variable to see if any or all of these signatures show a simultaneous anomaly due to the formation of the QGP. In addition, basic quantum chromodynamics phenomena, collision dynamics, and thermodynamic features of the initial states of the collision are studied. To achieve these goals, the PHENIX experiment measures lepton pairs (dielectrons and dimuons) to study various properties of vector mesons, such as the mass, the width, and the degree of yield suppression due to the formation of the QGP. The effect of thermal radiation on the continuum is studied in different regions of rapidity and mass. The e[mu] coincidence is measured to study charm production, and aids in understanding the shape of the continuum dilepton spectrum. Photons are measured to study direct emission of single photons and to study [pi][sup 0] and [eta] production. Charged hadrons are identified to study the spectrum shape, production of antinuclei, the [phi] meson (via K[sup +]K[sup [minus

    Abstract Controversies over race conceptualizations have been ongoing for centuries and have been shaped, in part, by anthropologists. Objective To assess anthropologists' views on race, genetics, and ancestry. Methods In 2012 a broad national survey of anthropologists examined prevailing views on race, ancestry, and genetics. Results Results demonstrate consensus that there are no human biological races and recognition that race exists as lived social experiences that can have important effe...

  17. Conceptual apraxia from lateralized lesions. (United States)

    Heilman, K M; Maher, L M; Greenwald, M L; Rothi, L J


    Models of praxis have posited two major components, production and conceptual. Conceptual praxis disorders may occur in two domains: associative knowledge (tool-action associations such as hammer pound; tool-object associations such as hammer nail) and mechanical knowledge such as knowing the advantage that tools afford. Patients with Alzheimer's disease not only have conceptual apraxia (CA) but can dissociate CA from language deficits and from praxis production deficits (ideomotor apraxia). These findings suggests that knowledge about tools (action semantics) is independent of verbal semantics as well as movement representations. To learn if conceptual praxis knowledge is stored in one hemisphere (right or left) and if associative and mechanical conceptual praxis knowledge can be dissociated, we studied 29 right-handed subjects with unilateral strokes. Ten had left-hemisphere damage with no ideomotor apraxia. Eleven had left-hemisphere damage with ideomotor apraxia. There were eight right-hemisphere-damaged controls and 10 normal controls. These subjects were given tests for conceptual apraxia. There was a significant difference between groups, the left-hemisphere group with ideomotor apraxia being most impaired on both the associative and mechanical CA tests. There was a trend for associative and mechanical knowledge to be dissociated. Although conceptual praxis representations are stored in the left hemisphere, analysis of lesion sites did not reveal where in the left hemisphere they may be stored.

  18. The Conceptual Framework of Thematic Mapping in Case Conceptualization. (United States)

    Ridley, Charles R; Jeffrey, Christina E


    This article, the 3rd in a series of 5, introduces the conceptual framework for thematic mapping, a novel approach to case conceptualization. The framework is transtheoretical in that it is not constrained by the tenets or concepts of any one therapeutic orientation and transdiagnostic in that it conceptualizes clients outside the constraints of diagnostic criteria. Thematic mapping comprises 4 components: a definition, foundational principles, defining features, and core concepts. These components of the framework, deemed building blocks, are explained in this article. Like the foundation of any structure, the heuristic value of the method requires that the building blocks have integrity, coherence, and sound anchoring. We assert that the conceptual framework provides a solid foundation, making thematic mapping a potential asset in mental health treatment. © 2017 Wiley Periodicals, Inc.

  3. Conceptual competence as a component of second language fluency. (United States)

    Andreou, Georgia; Galantomos, Ioannis


    In this article we argue that conceptual competence should be seen as a component of second language (L2) communicative competence. Abstract concepts are highly expressed by means of metaphors, metonymies, idioms and other types of figurative language. In literature it is suggested that knowledge and appropriate use of these lexical segments are closely related to L2 mastery and therefore conceptual instruction is expected to facilitate L2 learning. To test the relationship between conceptual and L2 competence we conducted an experiment in which Modern Greek learners were encouraged to express their views on the concept of happiness. The results showed their weak performance in conveying their ideas in a coherent and acceptable manner.

  4. Conceptual Integration using Wrapped Applications


    Gassner, Christian; Österle, Hubert; Hotaka, Ryosuke


    This paper describes how object-oriented concepts can be used throughout system development for integration purposes. Based on the distinction of physical and conceptual integration the concept of object wrapping is discussed for the integration of non-object-oriented systems. By regarding applications as high-level objects, i.e. wrapped applications, integration is achieved by modelling so-called integration relationships between these wrapped applications. While in conceptual integration re...

    mercury conceptual model and its four submodels (1. Methylation, 2. Bioaccumulation, 3. Human Health Effects, and 4. Wildlife Heath Effects) can be used to understand the general relationships among drivers and outcomes associated with mercury cycling in the Delta. Several linkages between important drivers and outcomes have been identified as important but highly uncertain (i.e. poorly understood). For example, there may be significant wildlife health effect of mercury on mammals and reptiles in the Delta, but there is currently very little or no information about it. The characteristics of such linkages are important when prioritizing and funding restoration projects and associated monitoring in the Delta and its tributaries.

    Full Text Available Hoy, gracias a los sistemas de posicionamiento global y dispositivos móviles equipados con sensores de rastreo, se puede recopilar una gran cantidad de datos sobre objetos móviles, es decir, datos espacio-temporales relacionados con el movimiento seguido por esos objetos. Por otro lado, las bodegas de datos, usualmente modeladas mediante una vista multidimensional de los datos, son bases de datos especializadas para soportar la toma de decisiones. Desafortunadamente, las bodegas de datos convencionales están principalmente orientadas al manejo de datos alfanuméricos. En este artículo, se incorporan elementos temporales a un modelo multidimensional conceptual espacial dando origen a un modelo multidimensional conceptual espacio-temporal. La propuesta se ilustra con un caso de estudio relacionado con la migración de animalesToday, thanks to global positioning systems technologies and mobile devices equipped with tracking sensors, and a lot of data about moving objects can be collected, e.g., spatio-temporal data related to the movement followed by objects. On the other hand, data warehouses, usually modeled using a multidimensional view of data, are specialized databases to support the decision-making process. Unfortunately, conventional data warehouses are mainly oriented to manage alphanumeric data. In this article, we incorporate temporal elements to a conceptual spatial multidimensional model resulting in a spatio-temporal multidimensional model. We illustrate our proposal with a case study related to animal migration.

  7. Conceptual structure within and between modalities

    Directory of Open Access Journals (Sweden)

    Katia eDilkina


    Full Text Available Current views of semantic memory share the assumption that conceptual representations are based on multi-modal experience, which activates distinct modality-specific brain regions. This proposition is widely accepted, yet little is known about how each modality contributes to conceptual knowledge and how the structure of this contribution varies across these multiple information sources. We used verbal feature lists, features from drawings and verbal co-occurrence statistics from latent semantic analysis to examine the informational structure in four domains of knowledge: perceptual, functional, encyclopedic and verbal. The goals of the analysis were three-fold: (1 to assess the structure within individual modalities; (2 to compare structures between modalities; and (3 to assess the degree to which concepts organize categorically or randomly.Our results indicated significant and unique structure in all four modalities: perceptually, concepts organize based on prominent features such as shape, size, color and parts; functionally, they group based on use and interaction; encyclopedically, they arrange based on commonality in location or behavior; and verbally, they group associatively or relationally. Visual/perceptual knowledge gives rise to the strongest hierarchical organization and is closest to classic taxonomic structure. Information is organized somewhat similarly in the perceptual and encyclopedic domains, which differs significantly from the structure in the functional and verbal domains. Notably, the verbal modality has the most unique organization, which is not at all categorical but also not random. The idiosyncrasy and complexity of conceptual structure across modalities begs the question of how all of these modality-specific experiences are fused together into coherent, multi-faceted yet unified concepts. Accordingly, both methodological and theoretical implications of the present findings are discussed.

  8. Conceptualizing innovation capabilities: A contingency perspective

    Directory of Open Access Journals (Sweden)

    Tor Helge Aas


    Full Text Available Empirical research has confirmed that a positive relationship exists between the implementation of innovation activities and the future performance of organizations. Firms utilize resources and capabilities to develop innovations in the form of new products, services or processes. Some firms prove to be better at reproducing innovation success than others, and the capacity to do so is referred to as innovation capability. However, the term innovation capability is ambiguously treated in extant literature. There are several different definitions of the concept and the distinction between innovation capabilities and other types of capabilities, such as dynamic capabilities, is neither explicitly stated, nor is the relationship between the concept and other resource- and capability-based concepts within strategy theory established. Although innovation is increasingly identified as crucial for a firm’s sustainable competitiveness in contemporary volatile and complex markets, the strategy-innovation link is underdeveloped in extant research. To overcome this challenge this paper raises the following research question: What type of innovation capabilities are required to innovate successfully? Due to the status of the extant research, we chose a conceptual research design to answer our research question and the paper contributes with a conceptual framework to discuss what innovation capabilities firms need to reproduce innovation success. Based on careful examination of current literature on innovation capability specifically, and the strategy-innovation link in general, we suggest that innovation capability must be viewed along two dimensions – innovation novelty and market characteristics. This framework enables the identification of four different contexts for innovation capabilities in a two-bytwo matrix. We discuss the types of innovation capabilities necessary within the four different contexts. This novel framework contributes to the

    Niinikoski, T O


    The conceptual design of an evaporative two-phase flow cooling system for the ATLAS SCT detector is described, using perfluorinated propane (C3F8) as a coolant. Comparison with perfluorinated butane (C4F10) is made, although the detailed design is presented only for C3F8. The two-phase pressure drop and heat transfer coefficient are calculated in order to determine the dimensions of the cooling pipes and module contacts for the Barrel SCT. The region in which the flow is homogeneous is determined. The cooling cycle, pipework, compressor, heat exchangers and other main elements of the system are calculated in order to be able to discuss the system control, safety and reliability. Evaporative cooling appears to be substantially better than the binary ice system from the point of view of safety, reliability, detector thickness, heat transfer coefficient, cost and simplicity.

    is analysed in the context of the artefact production process. The analysis is conducted in such a way as to keep the assumptions on which it is based explicit, plausible, and acceptable to common sense. The ‘obvious’ view of design representations as descriptions of possible or future things is rejected......Drawing on methods and literature from the field of philosophy, an account is given of the general nature of the artefact production process in order to provide a conceptual platform for design research. Designing itself is defined as the production of design representations; and the latter notion......, and so the major philosophical difficulty is to propose a reasonably precise definition of ‘design representation’ without implying the existence of such non-existent things. To overcome that difficulty, a definition is developed in terms of human agents, their actions and ideas (including intentions...

  11. On the possibility of intermittence during fixations: a conceptual assessment. (United States)

    Talasli, U


    A prevalent tacit assumption of the continuity of visual representation during fixations is challenged and shown to be logically tenuous. Relying upon three lines of suggestive evidence, it is then argued that representation must be in the form of static snapshots which alternate with very short dark periods wherein the image is omitted from vision. In view of the difficulties of a direct experimental verification of such a high-frequency intermittence, a conceptual approach to the question is defended.

  14. Irony comprehension: social conceptual knowledge and emotional response. (United States)

    Akimoto, Yoritaka; Sugiura, Motoaki; Yomogida, Yukihito; Miyauchi, Carlos Makoto; Miyazawa, Shiho; Kawashima, Ryuta


    Verbal irony conveys various emotional messages, from criticism to humor, that differ from the meaning of the actual words. To understand irony, we need conceptual knowledge of irony in addition to an understanding of context. We investigated the neural mechanism of irony comprehension, focusing on two overlooked issues: conceptual knowledge and emotional response. We studied 35 healthy subjects who underwent functional MRI. During the scan, the subject examined first-person-view stories describing verbal interactions, some of which included irony directed toward the subject. After MRI, the subject viewed the stories again and rated the degree of irony, humor, and negative emotion evoked by the statements. We identified several key findings about irony comprehension: (1) the right anterior superior temporal gyrus may be responsible for representing social conceptual knowledge of irony, (2) activation in the medial prefrontal cortex and the right anterior inferior temporal gyrus might underlie the understanding of context, (3) modulation of activity in the right amygdala, hippocampus, and parahippocampal gyrus is associated with the degree of irony perceived, and (4) modulation of activity in the right dorsolateral prefrontal cortex varies with the degree of humor perceived. Our results clarified the differential contributions of the neural loci of irony comprehension, enriching our understanding of pragmatic language communication from a social behavior point of view.

  16. Zograscopic Viewing

    Directory of Open Access Journals (Sweden)

    Jan Koenderink


    Full Text Available The “zograscope” is a “visual aid” (commonly known as “optical machine” in the 18th century invented in the mid-18th century, and in general use until the early 20th century. It was intended to view single pictures (thus not stereographic pairs with both eyes. The optics approximately eliminates the physiological cues (binocular disparity, vergence, accommodation, movement parallax, and image blur that might indicate the flatness of the picture surface. The spatial structure of pictorial space is due to the remaining pictorial cues. As a consequence, many (or perhaps most observers are aware of a heightened “plasticity” of the pictorial content for zograscopic as compared with natural viewing. We discuss the optics of the zograscope in some detail. Such an analysis is not available in the literature, whereas common “explanations” of the apparatus are evidently nonsensical. We constructed a zograscope, using modern parts, and present psychophysical data on its performance.

    Full Text Available Introduction. Most studies of psychologists and teachers in the phenomenon of conceptual thinking and ways of its formation are considered to be rather controversial and questionable. However, the research results were limited to the phenomenon of conceptual thinking and are therefore not representative for its implementation during the process of vocational training at the higher school. There is still considerable uncertainty with regard to the approaches to the problem of conceptual thinking in the humanities, including pedagogics and psychology. Furthermore, previous studies have not dealt with the objectives of conceptual thinking formation.The aims of the article are: to justify the use of the term “professional conceptualization of thinking” (PCT in theory and practice; to describe the prospects of the development of PCT in the training process.Methodology and research methods. The methodological base of the research involves the Russian psychological and pedagogical science approaches to the consideration of conceptual thinking as a higher mental function, a systematized and summarized form of cognitive reflection of notions and relations of reality. The experimental work was carried out using the method of observation, interviews, and tests. Quantitative and qualitative analysis of the data was conducted. The process of formation of PCT is described through the theory of stage-by-stage systematic development of mental acts.Results and scientific novelty. The concept “professional conceptualization of thinking” (PCT, a new one for psychological-pedagogical science, is suggested. The PCT levels are identified: ordinary, formal, substantial, system, and holistic. The objectives proposed for the development of the PCT levels in the process of professional education consist in the organization of consecutive transition from conscious mastering of a terminological framework to its use in the performance of educational tasks; from

  3. Conceptual Dynamics in Clinical Interviews (United States)

    Sherin, Bruce; Lee, Victor R.; Krakowski, Moshe


    One of the main tools that we have for the study of student science conceptions is the clinical interview. Research on student understanding of natural phenomena has tended to understand interviews as tools for reading out a student's knowledge. In this paper, we argue for a shift in how we think about and analyze interview data. In particular, we argue that we must be aware that the interview itself is a dynamic process during which a sort of conceptual change occurs. We refer to these short time-scale changes that occur over a few minutes in an interview as conceptual dynamics. Our goal is to devise new frameworks and techniques for capturing the conceptual dynamics. To this end, we have devised a simple and neutral cognitive framework. In this paper, we describe this framework, and we show how it can be applied to understand interview data. We hope to show that the conceptual dynamics of interviews are complex, but that it nonetheless feasible to make them a focus of study.

  9. Population theory-A long view. (United States)

    Kreager, Philip


    Any attempt to take a long view of population research, its findings, and applications is bound to raise questions about the state of population theory. Recent research on the history of population thought enables us to include a much more complete account of classical and early modern sources, and of parallel and complementary developments in population biology. This paper considers four major shifts in the conceptual and empirical ambitions of population inquiry over the long term. In general, major conceptual developments in ideas about population reflect major shifts in political and biological theory. The nature of population in European science and society was substantially established before demography emerged as a twentieth-century academic discipline focused chiefly on fertility and mortality. A long view suggests that demography is currently in the course of a shift that constructively re-integrates it with the wider field of scientific and historical population thinking.

    In an attempt to ensure more consistent casting results and remove some schedule variance associated with casting, an improved casting furnace concept has been developed. The improved furnace uses the existing arc melter hardware and glovebox utilities. The furnace concept was designed around physical and operational requirements such as; a charge sized of less than 30 grams, high heating rates and minimal additional footprint. The conceptual model is shown in the report as well as a summary of how the requirements were met.

  19. Conceptual Models for Search Engines (United States)

    Hendry, D. G.; Efthimiadis, E. N.

    Search engines have entered popular culture. They touch people in diverse private and public settings and thus heighten the importance of such important social matters as information privacy and control, censorship, and equitable access. To fully benefit from search engines and to participate in debate about their merits, people necessarily appeal to their understandings for how they function. In this chapter we examine the conceptual understandings that people have of search engines by performing a content analysis on the sketches that 200 undergraduate and graduate students drew when asked to draw a sketch of how a search engine works. Analysis of the sketches reveals a diverse range of conceptual approaches, metaphors, representations, and misconceptions. On the whole, the conceptual models articulated by these students are simplistic. However, students with higher levels of academic achievement sketched more complete models. This research calls attention to the importance of improving students' technical knowledge of how search engines work so they can be better equipped to develop and advocate policies for how search engines should be embedded in, and restricted from, various private and public information settings.

  20. Social responsibility: conceptualization and embodiment in a school of nursing. (United States)

    Kelley, Maureen A; Connor, Ann; Kun, Karen E; Salmon, Marla E


    This paper describes how a school of nursing has conceptualized and embodied social responsibility in its core values, curricular design, admission standards, clinical practice, and service learning opportunities. The school's engagement in the process of practicing social responsibility and clarifying its meaning and application has made apparent the natural linkage between social responsibility and professionalism and the deep and complex relationship between social responsibility and nursing itself. It has also revealed how a commitment to social responsibility impacts and determines for whom nurses care. Claiming social responsibility as a core value and working to refine its meaning and place has increased the school's commitment to it, concomitantly impacting education, practice, and recruitment and evaluation of faculty and students. The school views the conceptualization of social responsibility as a deepening and unfolding evolution, rather than as a formulaic understanding, and expects that its ongoing work of claiming social responsibility as a core value will continue to be enriching.

  1. Distributed and Conditional Documents: Conceptualizing Bibliographical Alterities

    Directory of Open Access Journals (Sweden)

    Johanna Drucker


    Full Text Available To conceptualize a future history of the book we have to recognize that our understanding of the bibliographical object of the past is challenged by the ontologically unbound, distributed, digital, and networked conditions of the present. As we draw on rich intellectual traditions, we must keep in view the need to let go of the object-centered approach that is at the heart of book history. My argument begins, therefore, with a few assertions. First, that we have much to learn from the scholarship on Old and New World contact that touches on bibliography, document studies, and book history for formulating a non-object centered conception of what a book is. Second, that the insights from these studies can be usefully combined with a theory of the “conditional” document to develop the model of the kinds of distributed artifacts we encounter on a daily basis in the networked conditions of current practices. Finally, I would suggest that this model provides a different conception of artifacts (books, documents, works of textual or graphic art, one in which reception is production and therefore all materiality is subject to performative engagement within varied, and specific, conditions of encounter.

  2. Similarities and differences in conceptualizing critical thinking

    Directory of Open Access Journals (Sweden)

    Pešić Jelena


    Full Text Available In this paper we explore the core similarities and differences in conceptualizing critical thinking. The framework of analysis refers to conceptions of leading critical thinking theorists: Ennis, Siegel, Paul, McPeck and Lipman. Two key questions are in the focus of consideration: which are the defining characteristics of critical thinking, distinguishing it from other types of thinking, and what are its constituents. The nature of identified differences has lead to a dilemma whether critical thinking skills are generalized or domain specific, as well as to the question regarding the role of noncognitive critical thinking dispositions. We also discuss the relation between the dominant approach founded in informal logic and epistemological conceptions that expanded the meaning of critical thinking by elaborating its reflective, dialectical and dialogical dimensions. The prevailing view that emphasizes the pragmatic purpose of critical thinking is contrasted with the competing Endeavour to base and justify its purpose in the concept of emancipatory rationality. The analysis outcomes suggest that, in spite of the lack of a consistent theoretical framework, competing conceptions do share some core principles, especially with respect to the distinctive features of critical thinking. However, there are deep and intrinsic differences regarding the nature of critical thinking standards and constituents, which can probably be attributed to complex and multidiscoursive nature of the concept itself. .

  4. The intersection of disability and healthcare disparities: a conceptual framework. (United States)

    Meade, Michelle A; Mahmoudi, Elham; Lee, Shoou-Yih


    This article provides a conceptual framework for understanding healthcare disparities experienced by individuals with disabilities. While health disparities are the result of factors deeply rooted in culture, life style, socioeconomic status, and accessibility of resources, healthcare disparities are a subset of health disparities that reflect differences in access to and quality of healthcare and can be viewed as the inability of the healthcare system to adequately address the needs of specific population groups. This article uses a narrative method to identify and critique the main conceptual frameworks that have been used in analyzing disparities in healthcare access and quality, and evaluating those frameworks in the context of healthcare for individuals with disabilities. Specific models that are examined include the Aday and Anderson Model, the Grossman Utility Model, the Institute of Medicine (IOM)'s models of Access to Healthcare Services and Healthcare Disparities, and the Cultural Competency model. While existing frameworks advance understandings of disparities in healthcare access and quality, they fall short when applied to individuals with disabilities. Specific deficits include a lack of attention to cultural and contextual factors (Aday and Andersen framework), unrealistic assumptions regarding equal access to resources (Grossman's utility model), lack of recognition or inclusion of concepts of structural accessibility (IOM model of Healthcare Disparities) and exclusive emphasis on supply side of the healthcare equation to improve healthcare disparities (Cultural Competency model). In response to identified gaps in the literature and short-comings of current conceptualizations, an integrated model of disability and healthcare disparities is put forth. We analyzed models of access to care and disparities in healthcare to be able to have an integrated and cohesive conceptual framework that could potentially address issues related to access to

  5. Students’ conceptual difficulties in hydrodynamics

    Alvaro Suarez


    Full Text Available We describe a study on the conceptual difficulties faced by college students in understanding hydrodynamics of ideal fluids. This study was based on responses obtained in hundreds of written exams complemented with several oral interviews, which were held with first-year engineering and science university students. Their responses allowed us to identify a series of misconceptions unreported in the literature so far. The study findings demonstrate that the most critical difficulties arise from the students’ inability to establish a link between the kinematics and dynamics of moving fluids, and from a lack of understanding regarding how different regions of a system interact.

    Full Text Available This article reports on the fndings of a qualitative study in which the construction of integrity of some business leaders was explored. Data were gathered through ten in-depth interviews with six South African business leaders commended to be champions of integrity. A grounded-theory approach to the data analysis elicited fve themes. These themes and their interrelatedness are discussed in this article and a conceptual framework of integrity is proposed. Integrity is conceptualised as a multifaceted and dynamic construct based on a moral foundation and inner drive that is managed by cognitive and affective processes manifesting various integrity-related behaviours.

  18. Planets, pluralism, and conceptual lineage (United States)

    Brusse, Carl


    Conceptual change can occur for a variety of reasons; some more scientifically significant than others. The 2006 definition of 'planet', which saw Pluto reclassified as a dwarf planet, is an example toward the more mundane end of the scale. I argue however that this case serves as a useful example of a related phenomenon, whereby what appears to be a single kind term conceals two or more distinct concepts with independent scientific utility. I examine the historical background to this case, as a template for developing additional evidence for pluralist approaches to conceptual disputes within science and elsewhere. "I would like to note that the two speakers who have spoken so far have both done the same extremely insulting gaffe," he said. "They have used the expression 'a physical definition of a planet' - by implication, suggesting that a dynamical definition is not physics!" He said he felt he had to teach the panel "something you should know": that dynamics was indeed physics, and in fact was addressed before solid-state physics in every textbook ever written."

  19. ADOxx Modelling Method Conceptualization Environment

    Directory of Open Access Journals (Sweden)

    Nesat Efendioglu


    Full Text Available The importance of Modelling Methods Engineering is equally rising with the importance of domain specific languages (DSL and individual modelling approaches. In order to capture the relevant semantic primitives for a particular domain, it is necessary to involve both, (a domain experts, who identify relevant concepts as well as (b method engineers who compose a valid and applicable modelling approach. This process consists of a conceptual design of formal or semi-formal of modelling method as well as a reliable, migratable, maintainable and user friendly software development of the resulting modelling tool. Modelling Method Engineering cycle is often under-estimated as both the conceptual architecture requires formal verification and the tool implementation requires practical usability, hence we propose a guideline and corresponding tools to support actors with different background along this complex engineering process. Based on practical experience in business, more than twenty research projects within the EU frame programmes and a number of bilateral research initiatives, this paper introduces the phases, corresponding a toolbox and lessons learned with the aim to support the engineering of a modelling method. ”The proposed approach is illustrated and validated within use cases from three different EU-funded research projects in the fields of (1 Industry 4.0, (2 e-learning and (3 cloud computing. The paper discusses the approach, the evaluation results and derived outlooks.

  1. Evolution beyond neo-Darwinism: a new conceptual framework. (United States)

    Noble, Denis


    Experimental results in epigenetics and related fields of biological research show that the Modern Synthesis (neo-Darwinist) theory of evolution requires either extension or replacement. This article examines the conceptual framework of neo-Darwinism, including the concepts of 'gene', 'selfish', 'code', 'program', 'blueprint', 'book of life', 'replicator' and 'vehicle'. This form of representation is a barrier to extending or replacing existing theory as it confuses conceptual and empirical matters. These need to be clearly distinguished. In the case of the central concept of 'gene', the definition has moved all the way from describing a necessary cause (defined in terms of the inheritable phenotype itself) to an empirically testable hypothesis (in terms of causation by DNA sequences). Neo-Darwinism also privileges 'genes' in causation, whereas in multi-way networks of interactions there can be no privileged cause. An alternative conceptual framework is proposed that avoids these problems, and which is more favourable to an integrated systems view of evolution. © 2015.

    Full Text Available Project-based learning (PBL consisting projects that integrate science, technology, society, history, mathematics, politics and even arts serves a productive discussion opportunity for students, fosters a student-directed inquiry of real world problems, gives them the excitement of learning and seen to be an effective teaching strategy. Therefore, examination of PBL from the practitioners’ point of view, interpretation of the conceptualizations and experiences of them would yield valuable indicators for future PBL processes in classes both for instructors and students. This study focused on the prospective science teachers’ conceptualizations about project-based learning as practitioners in this research but also as instructors of future. A group of 75 prospective science teachers took place in research for a period of ten weeks and conduct projects in groups of four to five based on science-technology-society issues. Multiple data sources were used consisted a questionnaire with open ended questions, project portfolios and presentation notes. Data collected analyzed qualitatively and some assertions generated with the help of conceptual constructs derived. Assertions generated indicated that prospective science teachers developed some varying understandings based on their experiences about conducting projects in the context of PBL.

  11. Conceptualizing functional cognition in stroke. (United States)

    Donovan, Neila J; Kendall, Diane L; Heaton, Shelley C; Kwon, Sooyeon; Velozo, Craig A; Duncan, Pamela W


    Up to 65% of individuals demonstrate poststroke cognitive impairments, which may increase hospital stay and caregiver burden. Randomized stroke clinical trials have emphasized physical recovery over cognition. Neuropsychological assessments have had limited utility in randomized clinical trials. These issues accentuate the need for a measure of functional cognition (the ability to accomplish everyday activities that rely on cognitive abilities, such as locating keys, conveying information, or planning activities). The aim of the study was to present the process used to establish domains of functional cognition for development of computer adaptive measure of functional cognition for stroke. Functional cognitive domains involved in identifying relevant neuropsychological constructs from the literature were conceptualized and finalized after advisory panel feedback from experts in neurology, neuropsychology, aphasiology, clinical trials, and epidemiology. The following 17 domains were proposed: receptive aphasia, expressive aphasia, agraphia, alexia, calculation, visuospatial, visuoperceptual, visuoconstruction, attention, language usage, executive functions, orientation, processing speed, memory, working memory, mood, awareness and abstract reasoning. The advisory panel recommended retaining the first 12 domains. Recommended changes included: to address only encoding and retrieval of recent information in the memory domain; to add domains for limb apraxia and poststroke depression; and to keep orientation as a separate domain or reclassify it under memory or attention. The final 10 domains included: language, reading and writing, numeric/calculation, limb praxis, visuospatial function, social use of language, emotional function, attention, executive function, and memory. Conceptualizing domains of functional cognition is the first step in developing a computer adaptive measure of functional cognition for stroke. Additional steps include developing, refining, and

    Hanuscin, Deborah; Lipsitz, Kelsey; Cisterna-Alburquerque, Dante; Arnone, Kathryn A.; van Garderen, Delinda; de Araujo, Zandra; Lee, Eun Ju


    The `conceptual storyline' of a lesson refers to the flow and sequencing of learning activities such that science concepts align and progress in ways that are instructionally meaningful to student learning of the concepts. Research demonstrates that when teachers apply lesson design strategies to create a coherent science content storyline, student learning is positively impacted (Roth et al., 2011). Because the conceptual storyline is often implicit within a lesson, and teachers often have difficulty articulating this aspect of lesson design (Lo et al., 2014), our professional development program engages elementary teachers in analyzing and developing graphic representations of a lesson's conceptual storyline to make that element explicit. In this exploratory study, we present typologies that represent two primary challenges teachers faced in developing coherent conceptual storylines in their lesson design, and examine the extent to which professional development enhanced their capacity to develop a coherent conceptual storyline.

  20. Government conceptual estimating for contracting and management (United States)

    Brown, J. A.


    The use of the Aerospace Price Book, a cost index, and conceptual cost estimating for cost-effective design and construction of space facilities is discussed. The price book consists of over 200 commonly used conceptual elements and 100 systems summaries of projects such as launch pads, processing facilities, and air locks. The cost index is composed of three divisions: (1) bid summaries of major Shuttle projects, (2) budget cost data sheets, and (3) cost management summaries; each of these divisions is described. Conceptual estimates of facilities and ground support equipment are required to provide the most probable project cost for budget, funding, and project approval purposes. Similar buildings, systems, and elements already designed are located in the cost index in order to make the best rough order of magnitude conceptual estimates for development of Space Shuttle facilities. An example displaying the applicability of the conceptual cost estimating procedure for the development of the KSC facilities is presented.

  1. The effect of visual deprivation on the organization of conceptual knowledge: testing the grounded cognition hypothesis. (United States)

    Marques, J Frederico


    The present paper evaluates the effect of visual deprivation on the organization and retrieval of conceptual knowledge. The experimental study used the release from proactive interference (PI-release) paradigm. Early onset blind (EOB) and sighted (S) subjects were tested with this task and additional visual and nonvisual property retrieval cues. PI-release results showed that the visual cue was less effective for EOB individuals than for S individuals, whereas the nonvisual cue was similarly effective for EOB individuals and S individuals. Results support a grounded view of cognition where the organization of conceptual knowledge depends on the role that sensory and motor channels play in its acquisition.

  2. Conceptual mediation: A new perspective on conceptual exchange (United States)

    Dawson, Chris; Lyndon, Harry


    For the last two decades science education researchers have had a major interest in identifying students’ intuitive understanding of a wide range of scientific topics and in reducing the difficulties involved when an attempt is made to replace these views by scientific understanding. Different approaches to this latter problem have been adopted by researchers, with strategies ranging from the pragmatic and atheoretical to those with a stronger theoretical foundation, usually based on some form of constructivism. In this paper we report on a novel theoretical perspective which takes as its foundation the psychological research of about three decades ago which investigated “forgetting,” and the important effects of previous knowledge in this process. In particular this new perspective demonstrates that, under normal teaching conditions, and through the process of proactive inhibition, the student’s prior knowledge can accelerate the forgetting of the newly taught scientific ideas. The paper first develops the theoretical position and then shows that a change in teaching approach can take advantage of the differences between the students’ prior understanding and the scientific view to ensure more efficient replacement. Following this an overview of the new methodology, as it is currently being used on a trial basis by science teachers in South Australia, is briefly introduced.

  3. The picture superiority effect in conceptual implicit memory: a conceptual distinctiveness hypothesis. (United States)

    Hamilton, Maryellen; Geraci, Lisa


    According to leading theories, the picture superiority effect is driven by conceptual processing, yet this effect has been difficult to obtain using conceptual implicit memory tests. We hypothesized that the picture superiority effect results from conceptual processing of a picture's distinctive features rather than a picture's semantic features. To test this hypothesis, we used 2 conceptual implicit general knowledge tests; one cued conceptually distinctive features (e.g., "What animal has large eyes?") and the other cued semantic features (e.g., "What animal is the figurehead of Tootsie Roll?"). Results showed a picture superiority effect only on the conceptual test using distinctive cues, supporting our hypothesis that this effect is mediated by conceptual processing of a picture's distinctive features.

    Patrick Nathan Lawlor

    Full Text Available Cancer and healthy cells have distinct distributions of molecular properties and thus respond differently to drugs. Cancer drugs ideally kill cancer cells while limiting harm to healthy cells. However, the inherent variance among cells in both cancer and healthy cell populations increases the difficulty of selective drug action. Here we formalize a classification framework based on the idea that an ideal cancer drug should maximally discriminate between cancer and healthy cells. More specifically, this discrimination should be performed on the basis of measurable cell markers. We divide the problem into three parts which we explore with examples. First, molecular markers should discriminate cancer cells from healthy cells at the single-cell level. Second, the effects of drugs should be statistically predicted by these molecular markers. Third, drugs should be optimized for classification performance. We find that expression levels of a handful of genes suffice to discriminate well between individual cells in cancer and healthy tissue. We also find that gene expression predicts the efficacy of some cancer drugs, suggesting that these cancer drugs act as suboptimal classifiers using gene profiles. Finally, we formulate a framework that defines an optimal drug, and predicts drug cocktails that may target cancer more accurately than the individual drugs alone. Conceptualizing cancer drugs as solving a discrimination problem in the high-dimensional space of molecular markers promises to inform the design of new cancer drugs and drug cocktails.

  5. Waste Handeling Building Conceptual Study

    Energy Technology Data Exchange (ETDEWEB)

    G.W. Rowe


    The objective of the ''Waste Handling Building Conceptual Study'' is to develop proposed design requirements for the repository Waste Handling System in sufficient detail to allow the surface facility design to proceed to the License Application effort if the proposed requirements are approved by DOE. Proposed requirements were developed to further refine waste handling facility performance characteristics and design constraints with an emphasis on supporting modular construction, minimizing fuel inventory, and optimizing facility maintainability and dry handling operations. To meet this objective, this study attempts to provide an alternative design to the Site Recommendation design that is flexible, simple, reliable, and can be constructed in phases. The design concept will be input to the ''Modular Design/Construction and Operation Options Report'', which will address the overall program objectives and direction, including options and issues associated with transportation, the subsurface facility, and Total System Life Cycle Cost. This study (herein) is limited to the Waste Handling System and associated fuel staging system.

  7. Paralinguistic correlates of conceptual structure. (United States)

    Barr, Dale J


    How is conceptual knowledge transmitted during conversation? When a speaker refers to an object, the name that the speaker chooses conveys information about category identity. In addition, I propose that a speaker's confidence in a classification can convey information about category structure. Because atypical instances of a category are more difficult to classify than typical instances, when speakers refer to these instances their lack of confidence will manifest itself "paralinguistically"--that is, in the form of hesitations, filled pauses, or rising prosody. These features can help listeners learn by enabling them to differentiate good from bad examples of a category. So that this hypothesis could be evaluated, in a category learning experiment participants learned a set of novel colors from a speaker. When the speaker's paralinguistically expressed confidence was consistent with the underlying category structure, learners acquired the categories more rapidly and showed better category differentiation from the earliest moments of learning. These findings have important implications for theories of conversational coordination and language learning.

  8. On (scientific) integrity: conceptual clarification. (United States)

    Patrão Neves, Maria do Céu


    The notion of "integrity" is currently quite common and broadly recognized as complex, mostly due to its recurring and diverse application in various distinct domains such as the physical, psychic or moral, the personal or professional, that of the human being or of the totality of beings. Nevertheless, its adjectivation imprints a specific meaning, as happens in the case of "scientific integrity". This concept has been defined mostly by via negativa, by pointing out what goes against integrity, that is, through the identification of its infringements, which has also not facilitated the elaboration of an overarching and consensual code of scientific integrity. In this context, it is deemed necessary to clarify the notion of "integrity", first etymologically, recovering the original meaning of the term, and then in a specifically conceptual way, through the identification of the various meanings with which the term can be legitimately used, particularly in the domain of scientific research and innovation. These two steps are fundamental and indispensable for a forthcoming attempt at systematizing the requirements of "scientific integrity".

  9. What is conceptual research in psychoanalysis? (United States)

    Leuzinger-Bohleber, Marianne; Fischmann, Tamara


    The development of psychoanalysis as a science and clinical practice has always relied heavily on various forms of conceptual research. Thus, conceptual research has clarified, formulated and reformulated psychoanalytic concepts permitting to better shape the findings emerging in the clinical setting. By enhancing clarity and explicitness in concept usage it has facilitated the integration of existing psychoanalytic thinking as well as the development of new ways of looking at clinical and extraclinical data. Moreover, it has offered conceptual bridges to neighbouring disciplines particularly interested in psychoanalysis, e.g. philosophy, sociology, aesthetics, history of art and literature, and more recently cognitive science/neuroscience. In the present phase of psychoanalytic pluralism, of worldwide scientific communication among psychoanalysts irrespective of language differences and furthermore of an intensifying dialogue with other disciplines, the relevance of conceptual research is steadily increasing. Yet, it still often seems insufficiently clear how conceptual research can be differentiated from clinical and empirical research in psychoanalysis. Therefore, the Subcommittee for Conceptual Research of the IPA presents some of its considerations on the similarities and the differences between various forms of clinical and extraclinical research, their specific aims, quality criteria and thus their specific chances as well as their specific limitations in this paper. Examples taken from six issues of the International Journal of Psychoanalysis in 2002-3 serve as illustrations for seven different subtypes of conceptual research.

  10. Fuzzy tool for conceptual modeling under uncertainty (United States)

    Walek, Bogdan; Klimes, Cyril


    This paper deals with the design of fuzzy tool for creating conceptual model under uncertainty. The paper identifies a problem in current approach of creating conceptual model of information system and suggests new methodics and tool for creating conceptual model, which can processes uncertain user requirements. The proposed tool uses a general model of the decision support system, that works with the vague input values and IF-THEN fuzzy rules, and creates a list of appropriate and acceptable solutions, and then allows to choose the best solution. In the proposed tool entities, attributes and relations between entitites in the resulting conceptual model are selected via a decision support system. In the paper we present six main parts of proposed tool, that generates suitable entities, attributes and relations between entities, then generates them to XML format and finally visualizes the resulting conceptual model. The created conceptual model illustrates the analysis of information system requirements. The proposed tool is shown on creating conceptual model of the hotel information system.

    Full Text Available Both organizations and institutions are social structures. On the basis of the institutions arethe formal rules and at the basis of the organizations are the interactions between peoples withcommon aims. The evolution of the institutions is explained by the institutionalism with its twoorientations: the new institutionalism and the old institutionalism. The last one was preoccupied bythe transformation of the economy and by the evolution of the technology and the newinstitutionalism explains the existence of the institutions from the individual’s point of view.Organizations were and are studied in present days from different point of views: organizationalstructure and culture, organizational change and development. The organization was classifiedaccording to several factors: aim, size, legal form, or their operational domain. Thecharacterization of the organization through metaphors such as machines, culture, brain, ororganism proves their complexity and diversity. Regarding to the relations between institution andorganization, the relationship could be characterised as interdependence because the organizationscan determine instituional changes, by offering a framework for the application of the rules.

  14. Personalizing knowledge delivery services: a conceptual framework (United States)

    Majchrzak, Ann; Chelleppa, Ramnath K.; Cooper, Lynne P.; Hars, Alexander


    Consistent with the call of the Minnesota Symposium for new theory in knowledge management, we offer a new conceptualization of Knowledge Management Systems (KMS) as a portfolio of personalized knowledge delivery services. Borrowing from research on online consumer behavior, we describe the challenges imposed by personalized knowledge delivery services, and suggest design parameters that can help to overcome these challenges. We develop our design constructs through a set of hypotheses and discuss the research implications of our new conceptualization. Finally, we describe practical implications suggested by our conceptualization - practical suggestions that we hope to gain some experience with as part of an ongoing action research project at our partner organization.

  15. Structural Analysis in a Conceptual Design Framework (United States)

    Padula, Sharon L.; Robinson, Jay H.; Eldred, Lloyd B.


    Supersonic aircraft designers must shape the outer mold line of the aircraft to improve multiple objectives, such as mission performance, cruise efficiency, and sonic-boom signatures. Conceptual designers have demonstrated an ability to assess these objectives for a large number of candidate designs. Other critical objectives and constraints, such as weight, fuel volume, aeroelastic effects, and structural soundness, are more difficult to address during the conceptual design process. The present research adds both static structural analysis and sizing to an existing conceptual design framework. The ultimate goal is to include structural analysis in the multidisciplinary optimization of a supersonic aircraft. Progress towards that goal is discussed and demonstrated.

    People make use of software applications in their activities, applying them as tools in carrying out tasks. That this use should be good for people--easy, effective, efficient, and enjoyable--is a principal goal of design. In this book, we present the notion of Conceptual Models, and argue that Conceptual Models are core to achieving good design. From years of helping companies create software applications, we have come to believe that building applications without Conceptual Models is just asking for designs that will be confusing and difficult to learn, remember, and use. We show how Concept

    Full Text Available Sustainable development is a model for resource use meant to satisfy human needs, without polluting the environment, so that these needs can be satisfied not only in the present, but in the future as well. It is a concept of nowadays with no generally accepted definition, placing environment first and foremost, aiming at implementing the environmental policies in all structures and at all economic levels. Within the present study we have aimed at creating a conceptual delimitation on sustainable development, sustainability and socialresponsibility, concepts of present interest, that tend to become a mystery for the academic community and practitioners by their variety and complexity of approaches. During our scientific endeavor we believe that social responsibility is the foundation of sustainable development. Sustainable development is a concept used especially at macro-economic level, while social responsibility is used at entity level and incorporates the economic, environmental and social dimension, which has a voluntary character and tries to respond to the information needs of the society and other stakeholders. Sustainability at the entity\\'s level is the goal or final objective of sustainable development – satisfaction of present needs without compromising the possibility for future generations to satisfy their own needs, while social responsibility is an intermediate phase of sustainability wherein entities try to balance the economic, social and environmental dimension. Thus, we can state we include ourselves within social corporatism, slightly close to social institutionalism, which is characteristic to developed countries, giving a particular importance to social contract and relations between entity and society. We believe that in Romania, a POSDRU funded project should be regarded as a legal person with social values, which must be based on sustainable development and to promote, besides legal liability of automatically deriving

    Students? academic experiences can influence their conceptualization of science. In contrast experts hold particular beliefs, perceptions, opinions, and attitudes about science that are often absent in first-year undergraduate students. Shifts toward more expert-like attitudes and views have been linked to improved student engagement, critical-thinking ability, conceptual understanding, and academic performance. In this study, we investigate shifts in attitudes and views toward science by stu...

  2. Quality Teaching in Science: an Emergent Conceptual Framework (United States)

    Jordens, J. Zoe; Zepke, Nick


    Achieving quality in higher education is a complex task involving the interrelationship of many factors. The influence of the teacher is well established and has led to some general principles of good teaching. However, less is known about the extent that specific disciplines influence quality teaching. The purposes of the paper are to investigate how quality teaching is perceived in the sciences and from these perceptions to develop for discussion a framework for teaching practice in the sciences. A New Zealand study explored the views of national teaching excellence award winners in science on quality teaching in undergraduate science. To capture all possible views from this expert panel, a dissensus-recognising Delphi method was used together with sensitising concepts based on complexity and wickedity. The emergent conceptual framework for quality teaching in undergraduate science highlighted areas of consensus and areas where there were a variety of views. About the purposes of science and its knowledge base, there was relative consensus, but there was more variable support for values underpinning science teaching. This highlighted the complex nature of quality teaching in science. The findings suggest that, in addition to general and discipline-specific influences, individual teacher values contribute to an understanding of quality in undergraduate science teaching.

    Directory of Open Access Journals (Sweden)



    Full Text Available After noting the importance of linguistic turn in the field of historiography, the two leading currents in the field of conceptual history are identi- fied, the Cambridge school and Reinhart Koselleck’s Begriffsgeschichte. The paper focuses on the analysis of the latter trend in conceptual history, linked to the phi- losophical (Heidegger, Gadamer, political (Schmitt and historical (Dilthey tradi- tion within the German academic community. The paper then reviews the origin and nature of the History of Pedagogy, which arose as part of the classic History of Ideas and later gave rise, after the Second World War, to a Social History of Education. Finally, a conceptual History of Education is proposed that, in addi- tion to addressing the various conceptual strata included in the different terms, also takes into account the intellectual and cultural aspects through a return to discourses and pedadogic narratives.

  10. Student initiative: A conceptual analysis

    Directory of Open Access Journals (Sweden)

    Polovina Nada


    Full Text Available In the description and scientific consideration of the attitude of children and youth towards their education and development, the concept of student initiative has been gaining ground lately, and it is hence the subject of analysis in this paper. The analysis is important because of the discrepancy between the increased efforts of the key educational policy holders to promote the idea about the importance of the development of student initiative and rare acceptance of this idea among theoreticians, researchers and practitioners dealing with the education and development of children and youth. By concretising the features of initiative student behaviour, our aim was, on the one hand, to observe the structural determinants and scientific status of the very concept of an initiative student, and, on the other, to contribute to the understanding of the initiative behaviour in practice. In the first part of the paper we deal with different notions and concretisations of the features of initiative behaviour of children and youth, which includes the consideration of: basic student initiative, academic student initiative, individual student initiative, the capacity for initiative and personal development initiative. In the second part of the paper, we discuss the relations of the concept of student initiative with the similar general concepts (activity/passivity, proactivity, agency and the concepts immediately related to school environment (student involvement, student participation. The results of our analysis indicate that the concept of student initiative has: particular features that differentiate it from similar concepts; the potential to reach the status of a scientific concept, bearing in mind the initial empirical specifications and general empirical verifiability of the yet unverified determinants of the concept. In the concluding part of the paper, we discuss the implications of the conceptual analysis for further research, as well as for

  11. Epistemological perspectives on conceptual change: Implications for educational practice (United States)

    Duschl, Richard A.; Gitomer, Drew H.

    Frameworks that seek to understand how knowledge restructuring occurs and how to build a learning environment that facilitates this restructuring raise important philosophical, psychological and pedagogical questions and issues about how conceptual change occurs and what characteristics of knowledge growth ought to be a part of curricula and learning environments. Implicit in emphasizing the how is a shift in science educations' perspective from one that embraces scientists' ways of knowing as the dominant objective towards one that favors positioning the learner for the next step. This change in perspective and approach represents a radical and complex departure from common practice. This article advances a piecemeal model of the character and mechanism of restructuring and then describes a model of educational practice designed to facilitate this form of restructuring. We argue that a piecemeal developmental perspective of conceptual change would offer quite different criteria for deciding what to teach and how to teach. The adoption of conceptual change teaching models implies teacher empowerment of a kind we have yet to fully understand. Empowering teachers with appropriate philosophical and psychological models for the selection and the sequencing of instructional tasks would aid in their describing and prescribing effective or meaningful learning strategies. Central to this educational model is a broadened and integrated view of assessment and instruction that we are calling a portfolio culture. The essential characteristic of this culture is that it creates opportunities for teachers and students to confront and develop their scientific understanding and to equip students with the tools necessary to take increased responsibility for their own restructuring, to assess for themselves what might be the next steps.

  12. Life cycle cost modeling of conceptual space vehicles (United States)

    Ebeling, Charles


    This paper documents progress to date by the University of Dayton on the development of a life cycle cost model for use during the conceptual design of new launch vehicles and spacecraft. This research is being conducted under NASA Research Grant NAG-1-1327. This research effort changes the focus from that of the first two years in which a reliability and maintainability model was developed to the initial development of a life cycle cost model. Cost categories are initially patterned after NASA's three axis work breakdown structure consisting of a configuration axis (vehicle), a function axis, and a cost axis. The focus will be on operations and maintenance costs and other recurring costs. Secondary tasks performed concurrent with the development of the life cycle costing model include continual support and upgrade of the R&M model. The primary result of the completed research will be a methodology and a computer implementation of the methodology to provide for timely cost analysis in support of the conceptual design activities. The major objectives of this research are: to obtain and to develop improved methods for estimating manpower, spares, software and hardware costs, facilities costs, and other cost categories as identified by NASA personnel; to construct a life cycle cost model of a space transportation system for budget exercises and performance-cost trade-off analysis during the conceptual and development stages; to continue to support modifications and enhancements to the R&M model; and to continue to assist in the development of a simulation model to provide an integrated view of the operations and support of the proposed system.

  13. Conceptual size representation in ventral visual cortex. (United States)

    Gabay, Shai; Kalanthroff, Eyal; Henik, Avishai; Gronau, Nurit


    Recent findings suggest that visual objects may be mapped along the ventral occipitotemporal cortex according to their real-world size (Konkle and Oliva, 2012). It has been argued that such mapping does not reflect an abstract, conceptual size representation, but rather the visual or functional properties associated with small versus big real-world objects. To determine whether a more abstract conceptual size representation may affect visual cortical activation we used meaningless geometrical shapes, devoid of semantic or functional associations, which were associated with specific size representations by virtue of extensive training. Following training, participants underwent functional magnetic resonance imaging (fMRI) scanning while performing a conceptual size comparison task on the geometrical shapes. In addition, a size comparison task was conducted for numeral digits denoting small and big numbers. A region-of-interest analysis revealed larger blood oxygenation level dependent (BOLD) responses for conceptually 'big' than for conceptually 'small' shapes, as well as for big versus small numbers, within medial (parahippocampal place area, PPA) and lateral (occipital place area, OPA) place-selective regions. Processing of the 'big' visual shapes further elicited enhanced activation in early visual cortex, possibly reflecting top-down projections from PPA. By using arbitrary shapes and numbers we minimized visual, categorical, or functional influences on fMRI measurement, providing evidence for a possible neural mechanism underlying the representation of abstract conceptual size within the ventral visual stream.

  14. Alternate conceptual model of ground water flow at Yucca Mountain

    Energy Technology Data Exchange (ETDEWEB)



    Attempts to predict the performance of a high-level nuclear waste repository in the United States have lead to the development of alternative conceptual models of the ground watre flow field in which the repository will be located. This step has come about because of the lage uncertainties involved in predicting the movement of water and radionuclides through an unsaturated fractured rock. Further, one of the standards to which we are comparing performance is probabilistic, so we are forced to try to conceive of all credible scenarios by which ground water may intersect the repository horizon and perhaps transport radionuclides to a given compliance boundary. To simplify this task, the DOE set about identifying alternative conceptual models of ground water flow which are consistent with existing data. Modeling these concepts necessitates the use of simplifying assumptions. Among the modeling assumptions commonly utilized by analysts of the Yucca Mountain site are those of uniformly distributed, small volumes of recharge and matrix or porous media flow. Most scientists would agree that recharge at Yucca Mountain does not occur in this ideal and simplified fashion, yet modeling endeavors continue to commonly utilize this approach. In this paper, we examine the potential effects of focused recharge on the flow field at Yucca Mountain in concert with a fractured matrix and non-equilibrium view of ground water flow.

  15. Low-Income Women’s Conceptualizations of Emotional- and Stress-Eating (United States)

    Hayman, Lenwood W.; Lee, Hannah J.; Miller, Alison L.; Lumeng, Julie C.


    Emotional- and stress-eating have been proposed as risk factors for obesity. However, the way that individuals conceptualize these behaviors is not well understood and no studies have employed a qualitative approach. We sought to understand how women conceptualize emotional- and stress-eating. Sixty-one low-income women from South-central Michigan with young children (ages 2–5 years) participated in either a focus group or individual semi-structured interview during which they were asked about their conceptualizations of eating behaviors among adults and children. Responses were transcribed and the constant comparative method was used to identify themes. Identified themes included that emotional- and stress-eating are viewed as uncommon, severe, pitiable behaviors that reflect a lack of self-control and are highly stigmatized; that when these behaviors occurred among children, the behaviors resulted from neglect or even abuse; and that bored-eating is viewed as distinct from emotional- or stress-eating and is a common and humorous behavior with which participants readily self-identified. Future research and interventions should seek to develop more detailed conceptualizations of these behaviors to improve measurement, destigmatize emotional- and stress-eating and potentially capitalize on the strong identification with bored-eating by targeting this behavior for interventions.

  17. The conceptualization of perceived insufficient milk among Mexican mothers. (United States)

    Sacco, Lisa M; Caulfield, Laura E; Gittelsohn, Joel; Martínez, Homero


    This study sought to provide a comprehensive picture of maternal conceptualization of Perceived Insufficient Milk (PIM) using qualitative methods (semistructured interviews, free lists, and rankings) in Mexico. Two hundred and seven first-time mothers of infants younger than 6 months and mothers-to-be who were (or intended to be) breastfeeding were interviewed in waiting areas at a hospital and a health clinic in Mexico City, Mexico, from September 2000 to January 2001. Pattern searching and triangulation of the 3 qualitative methods indicated that women viewed crying as the chief symptom of PIM. Maternal diet and liquid intake were cited as both the most salient causes and treatments for PIM. The main coping strategy in the event of PIM was formula feeding. These findings highlight the need for addressing maternal concerns in relation to PIM, especially regarding the role of crying as the initiator of the PIM cycle.

  18. Why older persons seek nursing care: towards a conceptual model. (United States)

    Boggatz, Thomas; Dassen, Theo


    Despite similar health problems, older persons show different care seeking behaviours for a variety of reasons. The aim of this study was to identify motives underlying the attitudes of older persons to seek nursing care and to develop a theoretical rationale which allows viewing their mutual interaction. Theory development according to Walker and Avant was used as a method to derive a model from the reviewed literature. Six categories were identified that may influence seeking of nursing care: perceived threat, disposition, external options & barriers, current coping abilities, influence of significant others, and outcome value. Findings do not allow determination of factors that may predict care seeking attitude but provide a loosely structured conceptual model for culture specific investigations. Qualitative studies guided by the model should be conducted in order to develop testable theories of care seeking for different cultures and settings. © 2011 Blackwell Publishing Ltd.

  19. Conceptual Design of the ITER ECE Diagnostic - An Update (United States)

    Austin, M. E.; Pandya, H. K. B.; Beno, J.; Bryant, A. D.; Danani, S.; Ellis, R. F.; Feder, R.; Hubbard, A. E.; Kumar, S.; Ouroua, A.; Phillips, P. E.; Rowan, W. L.


    The ITER ECE diagnostic has recently been through a conceptual design review for the entire system including front end optics, transmission line, and back-end instruments. The basic design of two viewing lines, each with a single ellipsoidal mirror focussing into the plasma near the midplane of the typical operating scenarios is agreed upon. The location and design of the hot calibration source and the design of the shutter that directs its radiation to the transmission line are issues that need further investigation. In light of recent measurements and discussion, the design of the broadband transmission line is being revisited and new options contemplated. For the instruments, current systems for millimeter wave radiometers and broad-band spectrometers will be adequate for ITER, but the option for employing new state-of-the-art techniques will be left open.

  20. Relational humility: conceptualizing and measuring humility as a personality judgment. (United States)

    Davis, Don E; Hook, Joshua N; Worthington, Everett L; Van Tongeren, Daryl R; Gartner, Aubrey L; Jennings, David J; Emmons, Robert A


    The study of humility has progressed slowly due to measurement problems. We describe a model of relational humility that conceptualizes humility as a personality judgment. In this set of 5 studies, we developed the 16-item Relational Humility Scale (RHS) and offered initial evidence for the theoretical model. In Study 1 (N = 300), we developed the RHS and its subscales--Global Humility, Superiority, and Accurate View of Self. In Study 2, we confirmed the factor structure of the scale in an independent sample (N = 196). In Study 3, we provided initial evidence supporting construct validity using an experimental design (N = 200). In Study 4 (N = 150), we provided additional evidence of construct validity by examining the relationships between humility and empathy, forgiveness, and other virtues. In Study 5 (N = 163), we adduced evidence of discriminant and incremental validity of the RHS compared with the Honesty-Humility subscale of the HEXACO-PI (Lee & Ashton, 2004).

  1. Spiritually Integrated Treatment of Depression: A Conceptual Framework

    Directory of Open Access Journals (Sweden)

    John R. Peteet


    Full Text Available Many studies have found an inverse correlation between religious/spiritual involvement and depression. Yet several obstacles impede spiritually integrated treatment of depressed individuals. These include specialization and fragmentation of care, inexperience of clinicians and spiritual care providers, ideological bias, boundary and ethical concerns, and the lack of an accepted conceptual framework for integrated treatment. Here I suggest a framework for approaching these obstacles, constructed from a unified view of human experience (having emotional, existential, and spiritual dimensions; spirituality seen as a response to existential concerns (in domains such as identity, hope, meaning/purpose, morality, and autonomy in relation to authority, which are frequently distorted and amplified in depression; a rationale for locating spiritually oriented approaches within a clinician's assessment, formulation, and treatment plan; and recognition of the challenges and potential pitfalls of integrated treatment.

  2. Conceptual Design of the ITER ECE Diagnostic – An Update

    Directory of Open Access Journals (Sweden)

    Ouroua A.


    Full Text Available The ITER ECE diagnostic has recently been through a conceptual design review for the entire system including front end optics, transmission line, and back-end instruments. The basic design of two viewing lines, each with a single ellipsoidal mirror focussing into the plasma near the midplane of the typical operating scenarios is agreed upon. The location and design of the hot calibration source and the design of the shutter that directs its radiation to the transmission line are issues that need further investigation. In light of recent measurements and discussion, the design of the broadband transmission line is being revisited and new options contemplated. For the instruments, current systems for millimeter wave radiometers and broad-band spectrometers will be adequate for ITER, but the option for employing new state-of-the-art techniques will be left open.

  3. "Origin," "creation," and "origin of life" some conceptual considerations. (United States)

    Charpa, Ulrich


    This paper opens by drawing attention to the fact that there is some conceptual confusion with regard to "origin" and "creation." This has its historical roots in the beginnings of modern science and undoubtedly affects our positioning towards the evolutionism/creationism-debate. This article argues that there are relevant ontological, epistemological, thematic, methodological, and logical differences between "origin" and "creation." As a result, the analysis suggests keeping the usage of both concepts strictly quite separate. Creation is not simply another word for origin nor does it stand for an (from a rigid scientific point of view) awkward example of an origin. Irrespective of the apparent similarities as explanatory factors, origin and creation belong to fundamentally different types of concepts. Consequently, "origin of life" and those scientific projects connected to it present themselves as something distinct that neither competes nor meshes with thinking about creation.

  5. Social network approaches to leadership: an integrative conceptual review. (United States)

    Carter, Dorothy R; DeChurch, Leslie A; Braun, Michael T; Contractor, Noshir S


    Contemporary definitions of leadership advance a view of the phenomenon as relational, situated in specific social contexts, involving patterned emergent processes, and encompassing both formal and informal influence. Paralleling these views is a growing interest in leveraging social network approaches to study leadership. Social network approaches provide a set of theories and methods with which to articulate and investigate, with greater precision and rigor, the wide variety of relational perspectives implied by contemporary leadership theories. Our goal is to advance this domain through an integrative conceptual review. We begin by answering the question of why-Why adopt a network approach to study leadership? Then, we offer a framework for organizing prior research. Our review reveals 3 areas of research, which we term: (a) leadership in networks, (b) leadership as networks, and (c) leadership in and as networks. By clarifying the conceptual underpinnings, key findings, and themes within each area, this review serves as a foundation for future inquiry that capitalizes on, and programmatically builds upon, the insights of prior work. Our final contribution is to advance an agenda for future research that harnesses the confluent ideas at the intersection of leadership in and as networks. Leadership in and as networks represents a paradigm shift in leadership research-from an emphasis on the static traits and behaviors of formal leaders whose actions are contingent upon situational constraints, toward an emphasis on the complex and patterned relational processes that interact with the embedding social context to jointly constitute leadership emergence and effectiveness.

  6. Conceptual and visual features contribute to visual memory for natural images.

    Directory of Open Access Journals (Sweden)

    Gesche M Huebner

    Full Text Available We examined the role of conceptual and visual similarity in a memory task for natural images. The important novelty of our approach was that visual similarity was determined using an algorithm [1] instead of being judged subjectively. This similarity index takes colours and spatial frequencies into account. For each target, four distractors were selected that were (1 conceptually and visually similar, (2 only conceptually similar, (3 only visually similar, or (4 neither conceptually nor visually similar to the target image. Participants viewed 219 images with the instruction to memorize them. Memory for a subset of these images was tested subsequently. In Experiment 1, participants performed a two-alternative forced choice recognition task and in Experiment 2, a yes/no-recognition task. In Experiment 3, testing occurred after a delay of one week. We analyzed the distribution of errors depending on distractor type. Performance was lowest when the distractor image was conceptually and visually similar to the target image, indicating that both factors matter in such a memory task. After delayed testing, these differences disappeared. Overall performance was high, indicating a large-capacity, detailed visual long-term memory.

  7. Metaphorical conceptualization of success in American success books, aphorisms and quotes

    Directory of Open Access Journals (Sweden)

    Łącka-Badura Jolanta


    Full Text Available The paper seeks to investigate how SUCCESS is conceptualized metaphorically in popular American success books, aphorisms and quotes. The study is based on an analysis of a corpus comprising over 600 utterances in which the lexical entry SUCCESS is regarded as constituting part of a metaphorical expression. The utterances have been extracted from the initial corpus of 10 success guide books, as well as 150 success aphorisms and quotes by famous Americans. The study investigates two aspects of this conceptualization. In the first instance, it examines which metaphorical source domains, as understood within the framework of Conceptual Metaphor Theory, prove to be most productive in the corpus. Secondly, in line with the frequently expressed views that the significance of conceptual metaphor as an explanatory construct is sometimes overstated in cognitive linguistic research, the paper attempts to analyze examples of linguistic metaphors which appear to be motivated in ways that are, at least in part, independent of well-established conceptual mappings, with particular emphasis on the resemblance-based and image metaphors associated with the predicate nominative forms ‘X is a Y’.

  8. The accommodation of science pedagogical knowledge: The application of conceptual change constructs to teacher education (United States)

    Stofflett, René T.

    The purposes of this study were to (a) determine whether the conditions of the accommodation of a science conception (IPDF) could be applied to pedagogical conceptions of science, and (b) using this application, determine whether a group of elementary teacher candidates in a conceptual change methods course accommodated their didactic preconceptions of science teaching. This research was based on the assumption that, for teachers to learn to teach for conceptual change, they must undergo a process of pedagogical conceptual change themselves. The teacher candidates in this study were interviewed and observed teaching. Their lesson plans and reflective papers were analyzed. The course was also videotaped to provide contextual descriptions. The teacher candidates, as expected, held primarily didactic pedagogical conceptions and were resistant to the conceptual change strategies. However, at posttest they found the new strategies to be intelligible, plausible, and fruitful. They also expressed implicit dissatisfaction with their preexisting views. Cooperating teachers had significant influence in the development of both plausibility and fruitfulness. Recommendations for improving the use of the conceptual change constructs in future teacher education research are made.Received: 22 June 1993; Revised: 19 April 1994;

  10. Learning in Earth and space science: a review of conceptual change instructional approaches (United States)

    Mills, Reece; Tomas, Louisa; Lewthwaite, Brian


    In response to calls for research into effective instruction in the Earth and space sciences, and to identify directions for future research, this systematic review of the literature explores research into instructional approaches designed to facilitate conceptual change. In total, 52 studies were identified and analyzed. Analysis focused on the general characteristics of the research, the conceptual change instructional approaches that were used, and the methods employed to evaluate the effectiveness of these approaches. The findings of this review support four assertions about the existing research: (1) astronomical phenomena have received greater attention than geological phenomena; (2) most studies have viewed conceptual change from a cognitive perspective only; (3) data about conceptual change were generated pre- and post-intervention only; and (4) the interventions reviewed presented limited opportunities to involve students in the construction and manipulation of multiple representations of the phenomenon being investigated. Based upon these assertions, the authors recommend that new research in the Earth and space science disciplines challenges traditional notions of conceptual change by exploring the role of affective variables on learning, focuses on the learning of geological phenomena through the construction of multiple representations, and employs qualitative data collection throughout the implementation of an instructional approach.

    This paper discusses the critical determinants of pressure ulcer development and proposes a new pressure ulcer conceptual framework. Recent work to develop and validate a new evidence-based pressure ulcer risk assessment framework was undertaken. This formed part of a Pressure UlceR Programme Of reSEarch (RP-PG-0407-10056), funded by the National Institute for Health Research. The foundation for the risk assessment component incorporated a systematic review and a consensus study that highlighted the need to propose a new conceptual framework. Discussion Paper. The new conceptual framework links evidence from biomechanical, physiological and epidemiological evidence, through use of data from a systematic review (search conducted March 2010), a consensus study (conducted December 2010-2011) and an international expert group meeting (conducted December 2011). A new pressure ulcer conceptual framework incorporating key physiological and biomechanical components and their impact on internal strains, stresses and damage thresholds is proposed. Direct and key indirect causal factors suggested in a theoretical causal pathway are mapped to the physiological and biomechanical components of the framework. The new proposed conceptual framework provides the basis for understanding the critical determinants of pressure ulcer development and has the potential to influence risk assessment guidance and practice. It could also be used to underpin future research to explore the role of individual risk factors conceptually and operationally. By integrating existing knowledge from epidemiological, physiological and biomechanical evidence, a theoretical causal pathway and new conceptual framework are proposed with potential implications for practice and research. © 2014 The Authors.

  1. Using resource graphs to represent conceptual change

    Directory of Open Access Journals (Sweden)

    Michael C. Wittmann


    Full Text Available We introduce resource graphs, a representation of linked ideas used when reasoning about specific contexts in physics. Our model is consistent with previous descriptions of coordination classes and resources. It represents mesoscopic scales that are neither knowledge-in-pieces nor large-scale concepts. We use resource graphs to describe several forms of conceptual change: incremental, cascade, wholesale, and dual construction. For each, we give evidence from the physics education research literature to show examples of each form of conceptual change. Where possible, we compare our representation to models used by other researchers. Building on our representation, we analyze another form of conceptual change, differentiation, and suggest several experimental studies that would help understand the differences between reform-based curricula.

  2. How Physicists Communicate Conceptual Meaning with Math (United States)

    Franklin, Scott


    Physics embeds conceptual meaning within a complex mathematical formalism. In this talk, I present a discourse analysis of faculty teaching with mathematical derivations, rearranging and simplifying equations to illuminate physical principles. Observations are interpreted through the lens of symbolic forms, conceptual and contextual meanings that are embedded in the equation. As an equation is manipulated, different forms are emphasized, subtly changing the physical interpretation. The symbolic forms framework can make explicit the motivations behind the mathematical ``moves'' in a derivation. Some manipulations change the dominant context from physics to mathematics. Other thematic manipulations -- e.g. grouping terms of a common variable -- reveal important conceptual points. While direct observational evidence supports the inference of these motivations, the reasoning is often hidden from the students. The study of mathematical discourse represents a new direction in which physics education researchers can study and inform the classroom.

  3. Being Moved: Linguistic Representation and Conceptual Structure

    Directory of Open Access Journals (Sweden)

    Milena eKuehnast


    Full Text Available This study explored the organisation of the semantic field and the conceptual structure of moving experiences by investigating German-language expressions referring to the emotional state of being moved. We used present and past participles of eight psychological verbs as primes in a free word-association task, as these grammatical forms place their conceptual focus on the eliciting situation and on the felt emotional state, respectively. By applying a taxonomy of basic knowledge types and computing the Cognitive Salience Index, we identified joy and sadness as key emotional ingredients of being moved, and significant life events and art experiences as main elicitors of this emotional state. Metric multidimensional scaling analyses of the semantic field revealed that the core terms designate a cluster of emotional states characterised by low degrees of arousal and slightly positive valence, the latter due to a nearly balanced representation of positive and negative elements in the conceptual structure of being moved.

  7. Conceptualizing violence for health and medical geography. (United States)

    DeVerteuil, Geoffrey


    Despite the fact that violence is a major threat to public health, the term itself is rarely considered as a phenomenon unto itself, and rarely figures explicitly in work by health and medical geographers. In response, I propose a definitionally and conceptually more robust approach to violence using a tripartite frame (interpersonal violence, structural violence, mass intentional violence) and suggest critical interventions through which to apply this more explicit and conceptually more robust approach: violence and embodiment via substance abuse in health geography, and structural violence via mental illness in medical geography.

  8. The philosophical implications of Russian conceptualism

    Directory of Open Access Journals (Sweden)

    Mikhail Epstein


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

    The potential public safety impacts from accidents in conceptual fusion power plants were investigated. Fusion was found to have some potential for accidents, as does any energy generating system. Functions of fusion power plants were identified that possess sufficient potential for an accidental release of toxic materials to the environment. An assessment was made of the impact of the potential accidents and recommendations are included for R and D that will allow incorporation of safety concerns in fusion power plant design. This work was based on a review of information available in conceptual design documents of fusion reactor systems.

  13. Triadic conceptual structure of the maximum entropy approach to evolution. (United States)

    Herrmann-Pillath, Carsten; Salthe, Stanley N


    Many problems in evolutionary theory are cast in dyadic terms, such as the polar oppositions of organism and environment. We argue that a triadic conceptual structure offers an alternative perspective under which the information generating role of evolution as a physical process can be analyzed, and propose a new diagrammatic approach. Peirce's natural philosophy was deeply influenced by his reception of both Darwin's theory and thermodynamics. Thus, we elaborate on a new synthesis which puts together his theory of signs and modern Maximum Entropy approaches to evolution in a process discourse. Following recent contributions to the naturalization of Peircean semiosis, pointing towards 'physiosemiosis' or 'pansemiosis', we show that triadic structures involve the conjunction of three different kinds of causality, efficient, formal and final. In this, we accommodate the state-centered thermodynamic framework to a process approach. We apply this on Ulanowicz's analysis of autocatalytic cycles as primordial patterns of life. This paves the way for a semiotic view of thermodynamics which is built on the idea that Peircean interpretants are systems of physical inference devices evolving under natural selection. In this view, the principles of Maximum Entropy, Maximum Power, and Maximum Entropy Production work together to drive the emergence of information carrying structures, which at the same time maximize information capacity as well as the gradients of energy flows, such that ultimately, contrary to Schrödinger's seminal contribution, the evolutionary process is seen to be a physical expression of the Second Law.

  14. The religion-in-the-science-classroom issue: Seeking graduate student conceptual change (United States)

    Loving, Cathleen C.; Foster, Andrea


    This study examines the extent to which science education graduate students enjoy a well-articulated position on the compatibility of science and religion and, as a result, are comfortable with their espoused views and plans for the role of religion in science classroom discussions. We were particularly interested in examining changes in student mental states as a legitimate form of conceptual change after a course intervention. This might be evidenced by the depth of understanding, level of reasoning, and degree of comfort with classroom application. The intervention first asked students to write a talk back to the author paper shortly after reading a provocative essay on the topic. This was followed by reading and discussing a variety of alternative views after which they wrote a more formal position paper on the science-religion topic. We first conducted a content analysis of both papers, developing separate concept maps of the overall class response in the first and second papers, noting changes in emphases. Adapting a current multidimensional model of conceptual change, we then developed an individual evaluation form based on categories that emerged in the class analysis, which were strikingly similar to the categories in the multidimensional model. These included ontological, epistemological, and social/affective dimensions of conceptual change. Both papers were scored in these three areas. The conceptual change for each student from talk-back to position paper was subsequently reported using individual graphs and citing text examples. Results showed conceptual change or improved mental state in all three categories for most students.

  15. The relevance of the philosophical 'mind-body problem' for the status of psychosomatic medicine: a conceptual analysis of the biopsychosocial model. (United States)

    Van Oudenhove, Lukas; Cuypers, Stefaan


    Psychosomatic medicine, with its prevailing biopsychosocial model, aims to integrate human and exact sciences with their divergent conceptual models. Therefore, its own conceptual foundations, which often remain implicit and unknown, may be critically relevant. We defend the thesis that choosing between different metaphysical views on the 'mind-body problem' may have important implications for the conceptual foundations of psychosomatic medicine, and therefore potentially also for its methods, scientific status and relationship with the scientific disciplines it aims to integrate: biomedical sciences (including neuroscience), psychology and social sciences. To make this point, we introduce three key positions in the philosophical 'mind-body' debate (emergentism, reductionism, and supervenience physicalism) and investigate their consequences for the conceptual basis of the biopsychosocial model in general and its 'psycho-biological' part ('mental causation') in particular. Despite the clinical merits of the biopsychosocial model, we submit that it is conceptually underdeveloped or even flawed, which may hamper its use as a proper scientific model.

  16. Exact and conceptual repetition dissociate conceptual memory tests: problems for transfer appropriate processing theory. (United States)

    McDermott, K B; Roediger, H L


    Three experiments examined whether a conceptual implicit memory test (specifically, category instance generation) would exhibit repetition effects similar to those found in free recall. The transfer appropriate processing account of dissociations among memory tests led us to predict that the tests would show parallel effects; this prediction was based upon the theory's assumption that conceptual tests will behave similarly as a function of various independent variables. In Experiment 1, conceptual repetition (i.e., following a target word [e.g., puzzles] with an associate [e.g., jigsaw]) did not enhance priming on the instance generation test relative to the condition of simply presenting the target word once, although this manipulation did affect free recall. In Experiment 2, conceptual repetition was achieved by following a picture with its corresponding word (or vice versa). In this case, there was an effect of conceptual repetition on free recall but no reliable effect on category instance generation or category cued recall. In addition, we obtained a picture superiority effect in free recall but not in category instance generation. In the third experiment, when the same study sequence was used as in Experiment 1, but with instructions that encouraged relational processing, priming on the category instance generation task was enhanced by conceptual repetition. Results demonstrate that conceptual memory tests can be dissociated and present problems for Roediger's (1990) transfer appropriate processing account of dissociations between explicit and implicit tests.

  17. Examining the influence of formative assessment on conceptual accumulation and conceptual change (United States)

    Tomita, Miki K.

    This study explored the effect of formative assessment on student achievement in science. Research in science education has shown that students enter science classrooms with previously formed explanatory models of the natural world; these naive "mental models" have a substantial influence on their learning of scientific conceptions. In general, conceptual change describes the pathway from pre-instructional or prior conceptions to a post-instructional or desired conception. Conceptual change involves a fundamental restructuring of a network of concepts rather than fitting new concepts into an existing conceptual network or structure. Research has shown that conceptual change is difficult to promote; for example, students may accumulate multiple conceptions over the course of instruction, including both new misconceptions and more scientifically-sound conceptions. Hellden and Solomon (2004) found that although students tended to evoke the same, less-scientific conceptions over time, they could produce more scientifically-sound conceptions during interviews with appropriate prompting; thus, students undergo conceptual accumulation rather than conceptual change. Students can recall scientifically-sound conceptions they have learned and may use them to reason, but they do so in partnership or hybridization with their less-scientific prior conceptions. Formative assessment, which focuses on providing immediate feedback by acting upon student understanding during the course of instruction, and conceptual change have both been linked to increased student achievement. Formative assessment is an instructional strategy that helps teachers to assess students' current understanding, identify the gap between current understanding and expected understanding, and provide immediate and useful feedback to students on how to close the gap. Formative assessment ranges from formal (e.g. embedded, planned-for interactions between teacher and entire class) to informal (e.g. on

  7. Conceptual modelling of human resource evaluation process

    Directory of Open Access Journals (Sweden)

    Negoiţă Doina Olivia


    Full Text Available Taking into account the highly diverse tasks which employees have to fulfil due to complex requirements of nowadays consumers, the human resource within an enterprise has become a strategic element for developing and exploiting products which meet the market expectations. Therefore, organizations encounter difficulties when approaching the human resource evaluation process. Hence, the aim of the current paper is to design a conceptual model of the aforementioned process, which allows the enterprises to develop a specific methodology. In order to design the conceptual model, Business Process Modelling instruments were employed - Adonis Community Edition Business Process Management Toolkit using the ADONIS BPMS Notation. The conceptual model was developed based on an in-depth secondary research regarding the human resource evaluation process. The proposed conceptual model represents a generic workflow (sequential and/ or simultaneously activities, which can be extended considering the enterprise’s needs regarding their requirements when conducting a human resource evaluation process. Enterprises can benefit from using software instruments for business process modelling as they enable process analysis and evaluation (predefined / specific queries and also model optimization (simulations.

    Rafael Feyh Jappur


    Full Text Available Introduction: It presents the development of a proposed conceptual model for digital educational games in the context of the classroom in which the analysis focused on learning for sustainable habits production and consumption in the residential environment. The existing conceptual models are more linked to the creation and recently with evaluation of the games. In the context of the implementation, most models focus more on the description of the games validation processes than in mediating the pedagogical practice itself. Therefore, the research question is about how to create, implement and evaluate digital educational games for teaching and learning process in the classroom, with the focus on learning the culture of sustainability in the residential environment. Methodology: As far as the methodological characterization is concerned, the investigation was supported by bibliographical and field research for data collection. It was emphasized the use of Design Science Research Methodology as methodological procedure for the development of the conceptual model. Results: The system has been tested in a pilot study in two groups of Young Apprentice Program at SENAC/SC to check its consistency. Conclusions: It was concluded based on the results produced by the application of the pilot that the proposed conceptual model contributes to the process of teaching and learning in the classroom.

  15. Human kinship, from conceptual structure to grammar. (United States)

    Jones, Doug


    Research in anthropology has shown that kin terminologies have a complex combinatorial structure and vary systematically across cultures. This article argues that universals and variation in kin terminology result from the interaction of (1) an innate conceptual structure of kinship, homologous with conceptual structure in other domains, and (2) principles of optimal, "grammatical" communication active in language in general. Kin terms from two languages, English and Seneca, show how terminologies that look very different on the surface may result from variation in the rankings of a universal set of constraints. Constraints on kin terms form a system: some are concerned with absolute features of kin (sex), others with the position (distance and direction) of kin in "kinship space", others with groups and group boundaries (matrilines, patrilines, generations, etc.). Also, kin terms sometimes extend indefinitely via recursion, and recursion in kin terminology has parallels with recursion in other areas of language. Thus the study of kinship sheds light on two areas of cognition, and their phylogeny. The conceptual structure of kinship seems to borrow its organization from the conceptual structure of space, while being specialized for representing genealogy. And the grammar of kinship looks like the product of an evolved grammar faculty, opportunistically active across traditional domains of semantics, syntax, and phonology. Grammar is best understood as an offshoot of a uniquely human capacity for playing coordination games.

  17. Conceptual metaphor and comprehension in business writing

    Directory of Open Access Journals (Sweden)

    Talita C Smit


    Full Text Available Recent research studies in cognitive linguistics (Gibbs, 1999; Kővecses, 2005; Lakoff, 1987; Lakoff & Johnson, 1980; Lakoff & Johnson, 1999 have demonstrated that metaphor is not merely a figure of speech. The findings of these studies have shown that metaphor influences a good deal of how people think as it comprises a specific mental, cross-domain mapping in the conceptual system (Balaban, 1999; Ibarretxe-Antuňanu, 1999; Lakoff, 2006; Lakoff & Johnson, 1980. This article looks at whether employing different conceptual metaphors in different versions of the same business report will have an effect on reader comprehension. A small-scale research study was conducted with a group of second-year university students, in which they were given one of two texts concerning the recovery of the economy. Both texts were adapted from a newspaper report and seeded with metaphors and metaphoric expressions. The multiple-choice questions that followed aimed to determine to what extent the readers’ comprehension and interpretation of the report were influenced by the different conceptual metaphors used. The findings indicate that language that served to introduce the sources or targets directly into the content did not necessarily have an effect on the processing of subsequent metaphors involving these concepts; however, it appeared that the surface patterns of metaphorical discourse did affect the inferences drawn about the different conceptual metaphors. It can thus be concluded that a specific metaphoric framework in written discourse does influence the interpretation of the content.

  3. The conceptualization model problem—surprise (United States)

    Bredehoeft, John


    The foundation of model analysis is the conceptual model. Surprise is defined as new data that renders the prevailing conceptual model invalid; as defined here it represents a paradigm shift. Limited empirical data indicate that surprises occur in 20-30% of model analyses. These data suggest that groundwater analysts have difficulty selecting the appropriate conceptual model. There is no ready remedy to the conceptual model problem other than (1) to collect as much data as is feasible, using all applicable methods—a complementary data collection methodology can lead to new information that changes the prevailing conceptual model, and (2) for the analyst to remain open to the fact that the conceptual model can change dramatically as more information is collected. In the final analysis, the hydrogeologist makes a subjective decision on the appropriate conceptual model. The conceptualization problem does not render models unusable. The problem introduces an uncertainty that often is not widely recognized. Conceptual model uncertainty is exacerbated in making long-term predictions of system performance. C'est le modèle conceptuel qui se trouve à base d'une analyse sur un modèle. On considère comme une surprise lorsque le modèle est invalidé par des données nouvelles; dans les termes définis ici la surprise est équivalente à un change de paradigme. Des données empiriques limitées indiquent que les surprises apparaissent dans 20 à 30% des analyses effectuées sur les modèles. Ces données suggèrent que l'analyse des eaux souterraines présente des difficultés lorsqu'il s'agit de choisir le modèle conceptuel approprié. Il n'existe pas un autre remède au problème du modèle conceptuel que: (1) rassembler autant des données que possible en utilisant toutes les méthodes applicables—la méthode des données complémentaires peut conduire aux nouvelles informations qui vont changer le modèle conceptuel, et (2) l'analyste doit rester ouvert au fait

  10. Aircraft Conceptual Design Using Vehicle Sketch Pad (United States)

    Fredericks, William J.; Antcliff, Kevin R.; Costa, Guillermo; Deshpande, Nachiket; Moore, Mark D.; Miguel, Edric A. San; Snyder, Alison N.


    Vehicle Sketch Pad (VSP) is a parametric geometry modeling tool that is intended for use in the conceptual design of aircraft. The intent of this software is to rapidly model aircraft configurations without expending the expertise and time that is typically required for modeling with traditional Computer Aided Design (CAD) packages. VSP accomplishes this by using parametrically defined components, such as a wing that is defined by span, area, sweep, taper ratio, thickness to cord, and so on. During this phase of frequent design builds, changes to the model can be rapidly visualized along with the internal volumetric layout. Using this geometry-based approach, parameters such as wetted areas and cord lengths can be easily extracted for rapid external performance analyses, such as a parasite drag buildup. At the completion of the conceptual design phase, VSP can export its geometry to higher fidelity tools. This geometry tool was developed by NASA and is freely available to U.S. companies and universities. It has become integral to conceptual design in the Aeronautics Systems Analysis Branch (ASAB) here at NASA Langley Research Center and is currently being used at over 100 universities, aerospace companies, and other government agencies. This paper focuses on the use of VSP in recent NASA conceptual design studies to facilitate geometry-centered design methodology. Such a process is shown to promote greater levels of creativity, more rapid assessment of critical design issues, and improved ability to quickly interact with higher order analyses. A number of VSP vehicle model examples are compared to CAD-based conceptual design, from a designer perspective; comparisons are also made of the time and expertise required to build the geometry representations as well.

  11. A conceptual model of suicide in rural areas. (United States)

    Stark, C R; Riordan, V; O'Connor, R


    Suicide is an important public health issue among rural communities although there is no single pattern of suicide in rural areas. Despite this, there are common themes in much of the research evidence on suicide in rural areas. From the published research in the area, a conceptual model of rural suicide has been developed which can be used by clinical and public health services when considering possible routes of intervention. A conceptual model can be defined as 'a type of diagram which shows a set of relationships between factors that are believed to impact or lead to a target condition'. The model presented here uses the 'Cry of pain/ Entrapment' model of suicide risk to build a framework of factors which are associated with suicide in rural areas. Cross-setting factors associated with suicide rates include gender, poverty, mental illness, substance use, biological factors including apparent genetic risk, coping skills and media coverage of suicide. There are, however, other factors that appear to have particular importance in rural areas. These include rural stressors, such as isolation and political and social exclusion; factors affecting support, including social support, cultural norms on help-seeking, stigma associated with mental illness service availability; factors affecting the decision to self-harm, including modelling and cultural views on self-harm, and issues affecting the likelihood of self-harm resulting in death, including method availability, norms on methods of self-harm and treatment availability after harm occurs. Identifying which of these areas are the greatest local priorities helps to target activity. This model provides a way of considering suicide in rural areas. Local staff can use it to consider which issues are most relevant to their area. It allows classification of existing interventions, and deciding which other areas of work might be of local value. For researchers and service planners, it provides a way of classifying

  12. A conceptual framework for evaluating data suitability for observational studies. (United States)

    Shang, Ning; Weng, Chunhua; Hripcsak, George


    To contribute a conceptual framework for evaluating data suitability to satisfy the research needs of observational studies. Suitability considerations were derived from a systematic literature review on researchers' common data needs in observational studies and a scoping review on frequent clinical database design considerations, and were harmonized to construct a suitability conceptual framework using a bottom-up approach. The relationships among the suitability categories are explored from the perspective of 4 facets of data: intrinsic, contextual, representational, and accessible. A web-based national survey of domain experts was conducted to validate the framework. Data suitability for observational studies hinges on the following key categories: Explicitness of Policy and Data Governance, Relevance, Availability of Descriptive Metadata and Provenance Documentation, Usability, and Quality. We describe 16 measures and 33 sub-measures. The survey uncovered the relevance of all categories, with a 5-point Likert importance score of 3.9 ± 1.0 for Explicitness of Policy and Data Governance, 4.1 ± 1.0 for Relevance, 3.9 ± 0.9 for Availability of Descriptive Metadata and Provenance Documentation, 4.2 ± 1.0 for Usability, and 4.0 ± 0.9 for Quality. The suitability framework evaluates a clinical data source's fitness for research use. Its construction reflects both researchers' points of view and data custodians' design features. The feedback from domain experts rated Usability, Relevance, and Quality categories as the most important considerations.

  13. Factors affecting employee turnover and sound retention strategies in business organization: a conceptual view


    Chowdhury Abdullah Al Mamun; Md. Nazmul Hasan


    “Employee turnover” as an expression is broadly used in business organization. Despite the fact that several studies have been performed on this topic, little research has been conducted on examining the causes and leading factors of turnover as well, as advising some feasible approaches, which can be applied by bosses to ensure that employees will continue in their respective organizations to enhance organizational effectiveness and productivity. The main purpose of this study is to determin...

  15. Pain Catastrophizing as Repetitive Negative Thinking: A Development of the Conceptualization (United States)

    Flink, Ida Landström; Boersma, Katja; Linton, Steven J.


    Pain catastrophizing is a well-known concept in the pain literature and has been recognized as one of the most powerful psychological determinants of negative outcomes for pain problems. However, relatively little effort has been put into developing its theoretical underpinnings. More specifically, the intrinsic function of catastrophizing is not explicitly dealt with in contemporary theoretical models. The aim of this article is to add to existing models by proposing a development of the conceptualization of catastrophizing that stresses its function as an emotion regulator. We argue that catastrophizing can be conceptualized as a form of negative repetitive thinking, which is abstract, intrusive, and difficult to disengage from. It has been argued that repetitive negative thinking is a form of ineffective problem solving that functions to downregulate negative affect and that it can be regarded as an avoidant coping strategy because it impedes processing of emotional and somatic responses. Thus, in our conceptualization, catastrophizing is proposed to be a form of problem-solving behavior that functions to reduce negative emotion triggered by pain, and other related stimuli. Furthermore, we argue that catastrophizing is preferably regarded as a process where cognitions, emotions, and overt behavior are intertwined and not viewed as separate entities. To underscore the latter, we suggest the term catastrophic worry. Our intention with this development of the conceptualization is to give rise to new ideas for research and clinical practice and to revitalize discussions about the theoretical framework around pain-related catastrophizing.

  16. Dissociation of rapid response learning and facilitation in perceptual and conceptual networks of person recognition. (United States)

    Valt, Christian; Klein, Christoph; Boehm, Stephan G


    Repetition priming is a prominent example of non-declarative memory, and it increases the accuracy and speed of responses to repeatedly processed stimuli. Major long-hold memory theories posit that repetition priming results from facilitation within perceptual and conceptual networks for stimulus recognition and categorization. Stimuli can also be bound to particular responses, and it has recently been suggested that this rapid response learning, not network facilitation, provides a sound theory of priming of object recognition. Here, we addressed the relevance of network facilitation and rapid response learning for priming of person recognition with a view to advance general theories of priming. In four experiments, participants performed conceptual decisions like occupation or nationality judgments for famous faces. The magnitude of rapid response learning varied across experiments, and rapid response learning co-occurred and interacted with facilitation in perceptual and conceptual networks. These findings indicate that rapid response learning and facilitation in perceptual and conceptual networks are complementary rather than competing theories of priming. Thus, future memory theories need to incorporate both rapid response learning and network facilitation as individual facets of priming. © 2014 The British Psychological Society.

  20. Formalizing Linguistic Conventions for Conceptual Models (United States)

    Becker, Jörg; Delfmann, Patrick; Herwig, Sebastian; Lis, Łukasz; Stein, Armin

    A precondition for the appropriate analysis of conceptual models is not only their syntactic correctness but also their semantic comparability. Assuring comparability is challenging especially when models are developed by different persons. Empirical studies show that such models can vary heavily, especially in model element naming, even if they express the same issue. In contrast to most ontology-driven approaches proposing the resolution of these differences ex-post, we introduce an approach that avoids naming differences in conceptual models already during modeling. Therefore we formalize naming conventions combining domain thesauri and phrase structures based on a lin-guistic grammar. This allows for guiding modelers automatically during the modeling process using standardized labels for model elements. Our approach is generic, making it applicable for any modeling language.

    Viktor Zhivov (†


    Full Text Available V. M. Zhivov’s introduction to Studies in Historical Semantics of the Russian Language in the Early Modern Period (2009, translated here for the first time, offers a critical survey of the historiography on Begriffsgeschichte, the German school of conceptual history associated with the work of Reinhart Koselleck, as well as of its application to the study of Russian culture.  By situating Begriffsgeschichte in the context of late-nineteenth and early twentieth-century European philosophy, particularly hermeneutics and phenomenology, the author points out the important, and as yet unacknowledged, role that Russian linguists have played in the development of a native school of conceptual history.  In the process of outlining this alternative history of the discipline, Zhivov provides some specific examples of the way in which the study of “historical semantics” can be used to analyze the development of Russian modernity.

    Gyuró Monika


    Full Text Available The intention of this article is to demonstrate, within the framework of cognitive linguistics (Lakoff and Johnson, 1980a, how slang words associated with substance abuse are conceptualized via metaphors. This study analyses recreational drug slang terms found in the Drug Slang Dictionary in order to reveal categories of metaphors involved in drug users’ language. The results of the data analysis effectively reveal that, within a thematic approach, classes of metaphor are coded to enable connections between metaphorical concepts and drug addicts’ physiological experiences in order to present their personal meanings and cognitive processes. The study also involves drug addicts’ narratives to identify conceptual metaphors in their experiences. Notably, it is argued within this research that figurative language use is also connected to the cultural background of users to a great extent.

  3. The conceptual framework of quantum field theory

    CERN Document Server

    Duncan, Anthony


    The book attempts to provide an introduction to quantum field theory emphasizing conceptual issues frequently neglected in more "utilitarian" treatments of the subject. The book is divided into four parts, entitled respectively "Origins", "Dynamics", "Symmetries", and "Scales". The emphasis is conceptual - the aim is to build the theory up systematically from some clearly stated foundational concepts - and therefore to a large extent anti-historical, but two historical Chapters ("Origins") are included to situate quantum field theory in the larger context of modern physical theories. The three remaining sections of the book follow a step by step reconstruction of this framework beginning with just a few basic assumptions: relativistic invariance, the basic principles of quantum mechanics, and the prohibition of physical action at a distance embodied in the clustering principle. The "Dynamics" section of the book lays out the basic structure of quantum field theory arising from the sequential insertion of quan...

    Directory of Open Access Journals (Sweden)

    Aurore eAvargues-Weber


    Full Text Available The ability to process visual information using relational rules allows for decisions independent of the specific physical attributes of individual stimuli. Until recently, the manipulation of relational concepts was considered as a prerogative of large mammalian brains. Here we show that individual free flying honeybees can learn to use size relationship rules to choose either the larger or smaller stimulus as the correct solution in a given context, and subsequently apply the learnt rule to novel colors and shapes providing that there is sufficient input to the long wavelength (green photoreceptor channel. Our results add a novel, size-based conceptual rule to the set of relational concepts that honeybees have been shown to master and underline the value of bees as an animal model for studying the emergence of conceptualization abilities.

  6. Conceptualization, Cognitive Process between Image and Word

    Directory of Open Access Journals (Sweden)

    Aurel Ion Clinciu


    Full Text Available The study explores the process of constituting and organizing the system of concepts. After a comparative analysis of image and concept, conceptualization is reconsidered through raising for discussion the relations of concept with image in general and with self-image mirrored in body schema in particular. Taking into consideration the notion of mental space, there is developed an articulated perspective on conceptualization which has the images of mental space at one pole and the categories of language and operations of thinking at the other pole. There are explored the explicative possibilities of the notion of Tversky’s diagrammatic space as an element which is necessary to understand the genesis of graphic behaviour and to define a new construct, graphic intelligence.

  7. Conceptual Model of User Adaptive Enterprise Application

    Directory of Open Access Journals (Sweden)

    Inese Šūpulniece


    Full Text Available The user adaptive enterprise application is a software system, which adapts its behavior to an individual user on the basis of nontrivial inferences from information about the user. The objective of this paper is to elaborate a conceptual model of the user adaptive enterprise applications. In order to conceptualize the user adaptive enterprise applications, their main characteristics are analyzed, the meta-model defining the key concepts relevant to these applications is developed, and the user adaptive enterprise application and its components are defined in terms of the meta-model. Modeling of the user adaptive enterprise application incorporates aspects of enterprise modeling, application modeling, and design of adaptive characteristics of the application. The end-user and her expectations are identified as two concepts of major importance not sufficiently explored in the existing research. Understanding these roles improves the adaptation result in the user adaptive applications.

  8. Conceptual Design of an APT Reusable Spaceplane (United States)

    Corpino, S.; Viola, N.

    This paper concerns the conceptual design of an Aerial Propellant Transfer reusable spaceplane carried out during our PhD course under the supervision of prof. Chiesa. The new conceptual design methodology employed in order to develop the APT concept and the main characteristics of the spaceplane itself will be presented and discussed. The methodology for conceptual design has been worked out during the last three years. It was originally thought for atmospheric vehicle design but, thanks to its modular structure which makes it very flexible, it has been possible to convert it to space transportation systems design by adding and/or modifying a few modules. One of the major improvements has been for example the conception and development of the mission simulation and trajectory optimisation module. The methodology includes as main characteristics and innovations the latest techniques of geometric modelling and logistic, operational and cost aspects since the first stages of the project. Computer aided design techniques are used to obtain a better definition of the product at the end of the conceptual design phase and virtual reality concepts are employed to visualise three-dimensional installation and operational aspects, at least in part replacing full-scale mock- ups. The introduction of parametric three-dimensional CAD software integrated into the conceptual design methodology represents a great improvement because it allows to carry out different layouts and to assess them immediately. It is also possible to link the CAD system to a digital prototyping software which combines 3D visualisation and assembly analysis, useful to define the so-called Digital Mock-Up at Conceptual Level (DMUCL) which studies the integration between the on board systems, sized with simulation algorithms, and the airframe. DMUCL represents a very good means to integrate the conceptual design with a methodology turned towards dealing with Reliability, Availability, Maintainability and

  10. A Preliminary study on the seismic conceptual design (United States)

    Zhao, Zhen; Xie, Lili


    The seismic conceptual design is an essential part of seismic design codes. It points out that the term "seismic conceptual design" should imply three aspects, i.e., the given concept itself, the specific provisions related to the given concept and the designing following the provisions. Seismic conceptual design can be classified into two categories: the strict or traditional seismic conceptual design and the generalized seismic conceptual design. The authors are trying to define for both conceptual designs their connotations and study their characteristics, in particular, the differences between them. Authors emphasize that both conceptual designs sound very close, however, their differences are apparent. The strict conceptual designs are usually worked out directly from engineering practice and/or lessons learnt from earthquake damage, while the generalized conceptual designs are resulted in a series of visions aiming to realize the general objectives of the seismic codes. The strict conceptual designs, (traditional conceptual designs) are indispensable elements of seismic codes in assuring designed structures safer and the generalized conceptual designs are playing key roles in directing to a more advanced and effective seismic codes.

    Directory of Open Access Journals (Sweden)

    Francisco Ângelo Coutinho


    Full Text Available This paper reports the building of a conceptual profile of ‘life’. We took as a starting point the hypothesis that the concept of life is polysemous, showing several possible meanings, and, thus, admitting a conceptual profile. We attempted to demarcate the zones that constitute this conceptual profile through a dialogic interplay between theoretical and empirical studies, involving at least three genetic domains: the sociocultural domain, by means of a review about the concept of life and its history; the ontogenetic, through a compilation of studies about students’ alternative conceptions about life; and the microgenetic, by gathering empirical data through questionnaires, answered by Biology majors, and interviews based on problem-situations, with graduate students in the fields of Ecology and Genetics. Taking into account epistemological and ontological aspects, we identified three zones, representing three levels of understanding of the life concept: “internalist”, including conceptions in which life is understood as a set of inherent processes or properties of living beings; “externalist”, amounting to an understanding of life as something external to and apart from living beings, often seen as something that comes from outside or tends to a goal that is beyond the living being; and “relational”, in which life is conceived as a relationship between entities and/or systems, and the definition itself is given in terms of relations.

  7. The Conceptualization of Digitally Networked Participation

    Directory of Open Access Journals (Sweden)

    Yannis Theocharis


    Full Text Available The conceptualization and measurement of political participation has been an issue vibrantly debated for more than 50 years. The arrival of digital media came to add important parameters to the debate complicating matters further. Digital media have added inexhaustive creative and nonpolitical ways to engage in social and political life that not only often appear to form the basis of political participation but also, in a plethora of everyday contexts, seem to become embedded into what eventually evolves to become a politically meaningful act. This article argues that digitally networked participation—and its manifestations—is a form of political participation and should be conceptualized, identified, and measured as one. Relying on recent conceptual and empirical work, it shows how various common manifestations of digitally networked participation conform to minimalist, targeted, and motivational definitions of political participation. Finally, tackling common misconceptions about the value of such acts, this article argues that nonpolitical forms of digitally networked participation can occasionally be far more impactful than forms of participation commonly accepted as political. This article concludes by recommending the systematic development of measures for digitally networked participation and its formal integration in the study of political participation.

  8. Validating Avionics Conceptual Architectures with Executable Specifications

    Directory of Open Access Journals (Sweden)

    Nils Fischer


    Full Text Available Current avionics systems specifications, developed after conceptual design, have a high degree of uncertainty. Since specifications are not sufficiently validated in the early development process and no executable specification exists at aircraft level, system designers cannot evaluate the impact of their design decisions at aircraft or aircraft application level. At the end of the development process of complex systems, e. g. aircraft, an average of about 65 per cent of all specifications have to be changed because they are incorrect, incomplete or too vaguely described. In this paper, a model-based design methodology together with a virtual test environment is described that makes complex high level system specifications executable and testable during the very early levels of system design. An aircraft communication system and its system context is developed to demonstrate the proposed early validation methodology. Executable specifications for early conceptual system architectures enable system designers to couple functions, architecture elements, resources and performance parameters, often called non-functional parameters. An integrated executable specification at Early Conceptual Architecture Level is developed and used to determine the impact of different system architecture decisions on system behavior and overall performance.

  10. Deep Borehole Field Test Conceptual Design Report

    Energy Technology Data Exchange (ETDEWEB)

    Hardin, Ernest L. [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)


    This report documents conceptual design development for the Deep Borehole Field Test (DBFT), including test packages (simulated waste packages, not containing waste) and a system for demonstrating emplacement and retrieval of those packages in the planned Field Test Borehole (FTB). For the DBFT to have demonstration value, it must be based on conceptualization of a deep borehole disposal (DBD) system. This document therefore identifies key options for a DBD system, describes an updated reference DBD concept, and derives a recommended concept for the DBFT demonstration. The objective of the DBFT is to confirm the safety and feasibility of the DBD concept for long-term isolation of radioactive waste. The conceptual design described in this report will demonstrate equipment and operations for safe waste handling and downhole emplacement of test packages, while contributing to an evaluation of the overall safety and practicality of the DBD concept. The DBFT also includes drilling and downhole characterization investigations that are described elsewhere (see Section 1). Importantly, no radioactive waste will be used in the DBFT, nor will the DBFT site be used for disposal of any type of waste. The foremost performance objective for conduct of the DBFT is to demonstrate safe operations in all aspects of the test.

  12. Scaffolding software: How does it influence student conceptual understanding and motivation? (United States)

    Butler, Kyle A.

    The purpose of this study was to determine the influence of scaffolding software on student conceptual understanding and motivation. This study also provides insight on how students use the scaffolding features found in Artemis and the extent to which features show a relationship to student conceptual understanding and motivation. A Randomized Solomon Four Group Design was used in this study. As students worked through a project based unit over photosynthesis, the students performed information seeking activities that were based on their own inquiry. For this purpose, the students in the experimental group used an example of scaffolding software called Artemis, while the students in the control group used a search engine of their choice. To measure conceptual understanding, the researcher analyzed student generated concept maps on photosynthesis using three different methods (quantitative, qualitative, hierarchical). To measure motivation, the researcher used a survey that measured motivation on five different indicators: intrinsic goal orientation, extrinsic goal orientation, task value, control of learning beliefs, self-efficacy for learning and performance. Finally, the researcher looked at the relationship and influence of the scaffolding features on two student performance scores at the end of the unit. This created a total of ten dependent variables in relationship to the treatment. Overall, the students used the collaborative features 25% of the time, the maintenance features 0.84% of the time, the organizational features 16% of the time, the saving/viewing features 7% of the time and the searching features 51% of the time. There were significant correlations between the saving/viewing features hits and the students' task value (r = .499, p learning and performance (r = .553, p r = .519, p r = .576, p < .01). Finally, the results indicated that the scaffolding features in Artemis did not influence student conceptual understanding and motivation.

    The following two themes form the foundation of Mikhail Gorbachev's world view: (1) nuclear arms have reached a new complexity in technical development and numbers, and in ability to control the weapons; and (2) a new trend in international relations is moving away from competition and rivalry and towards "interdependence" and…

  18. Conceptualizing Telehealth in Nursing Practice: Advancing a Conceptual Model to Fill a Virtual Gap. (United States)

    Nagel, Daniel A; Penner, Jamie L


    Increasingly nurses use various telehealth technologies to deliver health care services; however, there has been a lag in research and generation of empirical knowledge to support nursing practice in this expanding field. One challenge to generating knowledge is a gap in development of a comprehensive conceptual model or theoretical framework to illustrate relationships of concepts and phenomena inherent to adoption of a broad range of telehealth technologies to holistic nursing practice. A review of the literature revealed eight published conceptual models, theoretical frameworks, or similar entities applicable to nursing practice. Many of these models focus exclusively on use of telephones and four were generated from qualitative studies, but none comprehensively reflect complexities of bridging nursing process and elements of nursing practice into use of telehealth. The purpose of this article is to present a review of existing conceptual models and frameworks, discuss predominant themes and features of these models, and present a comprehensive conceptual model for telehealth nursing practice synthesized from this literature for consideration and further development. This conceptual model illustrates characteristics of, and relationships between, dimensions of telehealth practice to guide research and knowledge development in provision of holistic person-centered care delivery to individuals by nurses through telehealth technologies. © The Author(s) 2015.

  19. Influence of Learning Styles on Conceptual Learning of Physics (United States)

    Marin-Suarez, Teresita; Alarcon, Hugo


    Several studies have shown the influence of scientific reasoning on the conceptual learning of students in courses developed with methodologies that promote active learning. Given that learning styles may also influence conceptual learning of physics, a correlacional study was conducted which used two different approaches of learning styles: the Honey-Alonso and Felder-Silverman models. This quantitative study was performed in two groups of students using modeling instruction in a college course of introductory mechanics. The Force and Motion Conceptual Evaluation test (FMCE) was used to assess conceptual learning. The results of this work suggest the dependence of the conceptual learning of physics on the learning styles.

    Schneider, Marguerite; Lieb, Pamela


    The industrial organization economics (IOE) and resource-based view (RBV) schools contribute uniquely to the strategic management curriculum. However, presentation of the RBV is often inadequate or ineffective, in part due to faculty habit, students' conceptualization of knowledge as objective and readily transferable, and course pedagogy. We…

  4. Orchestrating student discourse opportunities and listening for conceptual understandings in high school science classrooms (United States)

    Kinard, Melissa Grass

    Scientific communities have established social mechanisms for proposing explanations, questioning evidence, and validating claims. Opportunities like these are often not a given in science classrooms (Vellom, Anderson, & Palincsar, 1993) even though the National Science Education Standards (NSES, 1996) state that a scientifically literate person should be able to "engage intelligently in public discourse and debate about important issues in science and technology" (National Research Council [NRC], 1996). Research further documents that students' science conceptions undergo little modification with the traditional teaching experienced in many high school science classrooms (Duit, 2003, Dykstra, 2005). This case study is an examination of the discourse that occurred as four high school physics students collaborated on solutions to three physics lab problems during which the students made predictions and experimentally generated data to support their predictions. The discourse patterns were initially examined for instances of concept negotiations. Selected instances were further examined using Toulmin's (2003) pattern for characterizing argumentation in order to understand the students' scientific reasoning strategies and to document the role of collaboration in facilitating conceptual modifications and changes. Audio recordings of the students' conversations during the labs, written problems turned in to the teacher, interviews of the students, and observations and field notes taken during student collaboration were used to document and describe the students' challenges and successes encountered during their collaborative work. The findings of the study indicate that collaboration engaged the students and generated two types of productive science discourse: concept negotiations and procedure negotiations. Further analysis of the conceptual and procedure negotiations revealed that the students viewed science as sensible and plausible but not as a tool they could

  6. Towards to An Explanation for Conceptual Change: A Mechanistic Alternative (United States)

    Rusanen, Anna-Mari


    Conceptual change is one of the most studied fields in science education and psychology of learning. However, there are still some foundational issues in conceptual change research on which no clear consensus has emerged. Firstly, there is no agreement on what changes in belief and concept systems constitute conceptual change and what changes do not. Secondly, there is no consensus on what the specific mechanisms of conceptual change are. Thirdly, there is no common explanatory framework of how to explain conceptual change. In this paper a sketch for explanations of conceptual change is outlined. According to this account, the explanation for conceptual change requires (1) a description for the information processing task and (2) a sufficiently accurate and detailed description of the cognitive mechanisms responsible for the task. The scope and limits of this type of explanation are discussed.

  7. How Much is Much?: a Conceptual Study of Web Traffic

    Directory of Open Access Journals (Sweden)

    Tord Høivik


    Full Text Available Valid and relevant statistics are required for library planning and advocacy. As libraries and their users turn to the web, library statistics must follow. In this paper we explore the use of three common traffic indicators to measure the impact of web resources from national libraries. We present and discuss the use of data on on page views, virtual visits and unique users, with examples from national, academic and public libraries. These indicators are in an early stage of development and need some conceptual and much empirical work to become good tools for strategic planning. But we note four findings: (1 the ratios between the three indicators are very unstable, so we must measure and interpret all three; (2 we find substantial differences between countries, with Denmark in a leading position; (3 in academic and national libraries the number of virtual visits is likely to overshadow the number of physical visits; (4 analysis of web traffic must be based on an understanding of J-shaped distributions (‘power laws’ rather than concepts drawn from ordinary well-behaved bell curves (‘normal distributions’.

  8. [Active ageing and success: A brief history of conceptual models]. (United States)

    Petretto, Donatella Rita; Pili, Roberto; Gaviano, Luca; Matos López, Cristina; Zuddas, Carlo


    The aim of this paper is to analyse and describe different conceptual models of successful ageing, active and healthy ageing developed in Europe and in America in the 20° century, starting from Rowe and Kahn's original model (1987, 1997). A narrative review was conducted on the literature on successful ageing. Our review included definition of successful ageing from European and American scholars. Models were found that aimed to describe indexes of active and healthy ageing, models devoted to describe processes involved in successful ageing, and additional views that emphasise subjective and objective perception of successful ageing. A description is also given of critiques on previous models and remedies according to Martin et al. (2014) and strategies for successful ageing according to Jeste and Depp (2014). The need is discussed for the enhancement of Rowe and Kahn's model and other models with a more inclusive, universal description of ageing, incorporating scientific evidence regarding active ageing.

  9. Adaptive multimodal interaction in mobile augmented reality: A conceptual framework (United States)

    Abidin, Rimaniza Zainal; Arshad, Haslina; Shukri, Saidatul A'isyah Ahmad


    Recently, Augmented Reality (AR) is an emerging technology in many mobile applications. Mobile AR was defined as a medium for displaying information merged with the real world environment mapped with augmented reality surrounding in a single view. There are four main types of mobile augmented reality interfaces and one of them are multimodal interfaces. Multimodal interface processes two or more combined user input modes (such as speech, pen, touch, manual gesture, gaze, and head and body movements) in a coordinated manner with multimedia system output. In multimodal interface, many frameworks have been proposed to guide the designer to develop a multimodal applications including in augmented reality environment but there has been little work reviewing the framework of adaptive multimodal interface in mobile augmented reality. The main goal of this study is to propose a conceptual framework to illustrate the adaptive multimodal interface in mobile augmented reality. We reviewed several frameworks that have been proposed in the field of multimodal interfaces, adaptive interface and augmented reality. We analyzed the components in the previous frameworks and measure which can be applied in mobile devices. Our framework can be used as a guide for designers and developer to develop a mobile AR application with an adaptive multimodal interfaces.

  10. Climate Change Conceptual Change: Scientific Information Can Transform Attitudes. (United States)

    Ranney, Michael Andrew; Clark, Dav


    Of this article's seven experiments, the first five demonstrate that virtually no Americans know the basic global warming mechanism. Fortunately, Experiments 2-5 found that 2-45 min of physical-chemical climate instruction durably increased such understandings. This mechanistic learning, or merely receiving seven highly germane statistical facts (Experiment 6), also increased climate-change acceptance-across the liberal-conservative spectrum. However, Experiment 7's misleading statistics decreased such acceptance (and dramatically, knowledge-confidence). These readily available attitudinal and conceptual changes through scientific information disconfirm what we term "stasis theory"--which some researchers and many laypeople varyingly maintain. Stasis theory subsumes the claim that informing people (particularly Americans) about climate science may be largely futile or even counterproductive--a view that appears historically naïve, suffers from range restrictions (e.g., near-zero mechanistic knowledge), and/or misinterprets some polarization and (noncausal) correlational data. Our studies evidenced no polarizations. Finally, we introduce website designed to directly enhance public "climate-change cognition." Copyright © 2016 Cognitive Science Society, Inc.

  11. "Family matters": a conceptual framework for genetic testing in children. (United States)

    McConkie-Rosell, Allyn; Spiridigliozzi, Gail A


    Genetic testing in minor children presents a complex ethical and social problem. Current guidelines state that genetic testing of children is recommended only under circumstances where a clear medical or psychosocial benefit to the child can be demonstrated. Because of the difficulty in determining a psychosocial benefit, the discussion about genetic testing of minors ultimately tends to focus on who has the right to make the decision and whose right to autonomy is jeopardized, the parent's or the child's, when there is no identified medical benefit. Historically, a western bioethics paradigm, Principlism, has been used to guide genetic counseling sessions and genetic-testing guidelines for minors. This bioethics paradigm is guided by the principles: respect for autonomy, beneficence, nonmaleficence, and justice. Genetic testing in children, when viewed through a traditional bioethics filter is limited by its focus on the individual because children are not only individuals, they are also integral parts of a larger social context, that of their family. Because this bioethics paradigm places a strong emphasis on individual autonomy, the family's beliefs and values and the parents' concern for their children may be overshadowed by the medical community's attempt to preserve the child's "right" to an autonomous decision about genetic testing. The purpose of this paper is to first discuss the circumstances in which genetic testing of minors occurs and then present a theoretical and ethics-based conceptual framework that may be useful in the development of genetic counseling interventions.

  12. Impact of Animation on Assessment of Conceptual Understanding in Physics (United States)

    Dancy, Melissa H.


    This study investigates the effect of computer animation on assessment and the conditions under which animation may improve or hinder assessment of conceptual understanding in physics. An instrument was developed by replacing static pictures and descriptions of motion with computer animations on the Force Concept Inventory, a commonly used pencil and paper test. Both quantitative and qualitative data were collected. The animated and static versions of the test were given to students and the results were statistically analyzed. Think-aloud interviews were also conducted to provide additional insight into the statistical findings. We found that good verbal skills tended to increase performance on the static version but not on the animated version of the test. In general, students had a better understanding of the intent of the question when viewing an animation and gave an answer that was more indicative of their actual understanding, as reflected in separate interviews. In some situations this led students to the correct answer and in others it did not. Overall, we found that animation can improve assessment under some conditions by increasing the validity of the instrument.

  13. A Conceptual Model for Stream Restoration in Western New York: A Developing Case Study in the Elton Creek Watershed (United States)

    Rabideau, A.; Blersch, S. S.


    The practice of ecosystem restoration is still often viewed as an "art" versus a science. This view is further fueled by the manner in which many restoration projects are identified and implemented- on a case by case basis with little documentation on the drivers of the ecosystems in question or the establishment of success criteria once the project is complete. While monitoring data may exist to quantify the existing conditions of a stream (biological, chemical, and physical), these data are not always easily translated into design criteria for restoration. Rather, most restoration designs rely upon best professional judgment by highly experienced practitioners. Various agencies in Western New York have completed numerous stream restoration projects in the region to improve in-stream habitat and address impaired streams. In order to capture these successful restoration practices in a manner that can be translated to other streams in the region and inform future restoration designs, a conceptual framework is proposed for the Western New York region. The conceptual framework will identify the ecosystem drivers in the stream riparian corridors and discuss trajectories of these ecosystems. A project site on Elton Creek near Delevan, New York has been selected as a test case for applying this conceptual framework. The focus of this paper will be on determining the drivers of the stream ecosystem through the use of rapid geomorphic assessments. The results of two rapid geomorphic assessment methods be presented and contrasted in the context of the conceptual framework.

  14. Defining disease beyond conceptual analysis: an analysis of conceptual analysis in philosophy of medicine. (United States)

    Lemoine, Maël


    Conceptual analysis of health and disease is portrayed as consisting in the confrontation of a set of criteria--a "definition"--with a set of cases, called instances of either "health" or "disease." Apart from logical counter-arguments, there is no other way to refute an opponent's definition than by providing counter-cases. As resorting to intensional stipulation (stipulation of meaning) is not forbidden, several contenders can therefore be deemed to have succeeded. This implies that conceptual analysis alone is not likely to decide between naturalism and normativism. An alternative to this approach would be to examine whether the concept of disease can be naturalized.

    Analyses were performed to evaluate the performance of the low enriched uranium (LEU) conceptual design fuel for the conversion of the Transient Reactor Test Facility (TREAT) from its current highly enriched uranium (HEU) fuel. TREAT is an experimental nuclear reactor designed to produce high neutron flux transients for the testing of reactor fuels and other materials. TREAT is currently in non-operational standby, but is being restarted under the U.S. Department of Energy’s Resumption of Transient Testing Program. The conversion of TREAT is being pursued in keeping with the mission of the Department of Energy National Nuclear Security Administration’s Material Management and Minimization (M3) Reactor Conversion Program. The focus of this study was to demonstrate that the converted LEU core is capable of maintaining the performance of the existing HEU core, while continuing to operate safely. Neutronic and thermal hydraulic simulations have been performed to evaluate the performance of the LEU conceptual-design core under both steady-state and transient conditions, for both normal operation and reactivity insertion accident scenarios. In addition, ancillary safety analyses which were performed for previous LEU design concepts have been reviewed and updated as-needed, in order to evaluate if the converted LEU core will function safely with all existing facility systems. Simulations were also performed to evaluate the detailed behavior of the UO2-graphite fuel, to support future fuel manufacturing decisions regarding particle size specifications. The results of these analyses will be used in conjunction with work being performed at Idaho National Laboratory and Los Alamos National Laboratory, in order to develop the Conceptual Design Report project deliverable.

  16. A multidisciplinary conceptualization of conservation opportunity. (United States)

    Moon, Katie; Adams, Vanessa M; Januchowski-Hartley, Stephanie R; Polyakov, Maksym; Mills, Morena; Biggs, Duan; Knight, Andrew T; Game, Edward T; Raymond, Christopher M


    An opportunity represents an advantageous combination of circumstances that allows goals to be achieved. We reviewed the nature of opportunity and how it manifests in different subsystems (e.g., biophysical, social, political, economic) as conceptualized in other bodies of literature, including behavior, adoption, entrepreneur, public policy, and resilience literature. We then developed a multidisciplinary conceptualization of conservation opportunity. We identified 3 types of conservation opportunity: potential, actors remove barriers to problem solving by identifying the capabilities within the system that can be manipulated to create support for conservation action; traction, actors identify windows of opportunity that arise from exogenous shocks, events, or changes that remove barriers to solving problems; and existing, everything is in place for conservation action (i.e., no barriers exist) and an actor takes advantage of the existing circumstances to solve problems. Different leverage points characterize each type of opportunity. Thus, unique stages of opportunity identification or creation and exploitation exist: characterizing the system and defining problems; identifying potential solutions; assessing the feasibility of solutions; identifying or creating opportunities; and taking advantage of opportunities. These stages can be undertaken independently or as part of a situational analysis and typically comprise the first stage, but they can also be conducted iteratively throughout a conservation planning process. Four types of entrepreneur can be identified (business, policy, social, and conservation), each possessing attributes that enable them to identify or create opportunities and take advantage of them. We examined how different types of conservation opportunity manifest in a social-ecological system (the Great Barrier Reef) and how they can be taken advantage of. Our multidisciplinary conceptualization of conservation opportunity strengthens and

  17. Towards a conceptual framework for identifying student difficulties with solving Real-World Problems in Physics

    DEFF Research Database (Denmark)

    Niss, Martin


    This paper develops a conceptual framework for identifying the challenges and obstacles university students encounter when solving real-world problems involving Physics. The framework is based on viewing problem solving as a modelling process. In order to solve a real-world problem, the problem...... solver has to go through the steps and do the tasks of such a process. The paper presents a theoretical analysis of what it takes to solve three real-world problems, demonstrating how the framework presented captures the essential aspects of solving them. Moreover, it is argued that three steps critical...... solving in Physics is placed within the framework....

    We describe a framework affording computation of conceptual pathways between a pair of terms presented as a query to a text database. In this framework, information is extracted from text sentences and becomes represented in natural logic, which is a form of logic coming much closer to natural...... language than predicate logic. Natural logic accommodates a variety of scientific parlance, ontologies and domain models. It also supports a semantic net or graph view of the knowledge base. This admits computation of relationships between concepts simultaneously through pathfinding in the knowledge base...

  19. Studio with a view (United States)

    Hoover, Anthony K.


    Berklee College of Music (in Boston) needed a new studio in which to teach stereo mixing and critical listening. A small synthesis lab (adjacent to the main lobby, directly over the cafeteria kitchen, penetrated by exhaust ducts, and next to a bathroom) was chosen for renovation. The primary requirements were for maximum visibility to assure hopeful future engineers a full view of all the cool gear, and comfortable seating for fifteen students. The challenges, to be discussed, included isolation with a view, quiet HVAC, and great sound, in a space that was acoustically too small and in the wrong place. The best verification of success is its popularity, which has prevented the author from booking time for listening or testing.

  20. Stereoscopic optical viewing system (United States)

    Tallman, C.S.


    An improved optical system which provides the operator with a stereoscopic viewing field and depth of vision, particularly suitable for use in various machines such as electron or laser beam welding and drilling machines. The system features two separate but independently controlled optical viewing assemblies from the eyepiece to a spot directly above the working surface. Each optical assembly comprises a combination of eye pieces, turning prisms, telephoto lenses for providing magnification, achromatic imaging relay lenses and final stage pentagonal turning prisms. Adjustment for variations in distance from the turning prisms to the workpiece, necessitated by varying part sizes and configurations and by the operator's visual accuity, is provided separately for each optical assembly by means of separate manual controls at the operator console or within easy reach of the operator.

  1. Concert Viewing Headphones

    Directory of Open Access Journals (Sweden)

    Kazuya Atsuta


    Full Text Available An audiovisual interface equipped with a projector, an inclina-tion sensor, and a distance sensor for zoom control has been developed that enables a user to selectively view and listen to specific performers in a video-taped group performance. Dubbed Concert Viewing Headphones, it has both image and sound processing functions. The image processing extracts the portion of the image indicated by the user and projects it free of distortion on the front and side walls. The sound processing creates imaginary microphones for those performers without one so that the user can hear the sound from any performer. Testing using images and sounds captured using a fisheye-lens camera and 37 lavalier microphones showed that sound locali-zation was fastest when an inverse square function was used for the sound mixing and that the zoom function was useful for locating the desired sound performance.

  2. Conceptualizing transformations in child and adult psychoanalysis. (United States)

    Olesker, Wendy; Lament, Claudia


    A study group on Conceptualizing Transformation in Child and Adult Analysis focused on a particular kind of change in analysis, that of transformational change, a change in organization that could not be predicted from what came before. We found that, based on careful presentations of four analytic cases, transformational or pre-transformational change did take place. A central intervening variable was the patient's development of a sense of agency. We tried to articulate the nature of the interventions leading to agency and ultimately to transformation. We added other new dimensions: an emphasis on construction in addition to reconstruction and a focus on the future.

  3. A conceptual model of political market orientation

    DEFF Research Database (Denmark)

    Ormrod, Robert P.


    This article proposes eight constructs of a conceptual model of political market orientation, taking inspiration from the business and political marketing literature. Four of the constructs are 'behavioural' in that they aim to describe the process of how information flows through the organisation....... The remaining four constructs are attitudinal, designed to capture the awareness of members to the activities and importance of stakeholder groups in society, both internal and external to the organisation. The model not only allows the level of a party's political market orientation to be assessed, but also...

  4. Uncertainty and the Conceptual Site Model (United States)

    Price, V.; Nicholson, T. J.


    Our focus is on uncertainties in the underlying conceptual framework upon which all subsequent steps in numerical and/or analytical modeling efforts depend. Experienced environmental modelers recognize the value of selecting an optimal conceptual model from several competing site models, but usually do not formally explore possible alternative models, in part due to incomplete or missing site data, as well as relevant regional data for establishing boundary conditions. The value in and approach for developing alternative conceptual site models (CSM) is demonstrated by analysis of case histories. These studies are based on reported flow or transport modeling in which alternative site models are formulated using data that were not available to, or not used by, the original modelers. An important concept inherent to model abstraction of these alternative conceptual models is that it is "Far better an approximate answer to the right question, which is often vague, than the exact answer to the wrong question, which can always be made precise." (Tukey, 1962) The case histories discussed here illustrate the value of formulating alternative models and evaluating them using site-specific data: (1) Charleston Naval Site where seismic characterization data allowed significant revision of the CSM and subsequent contaminant transport modeling; (2) Hanford 300-Area where surface- and ground-water interactions affecting the unsaturated zone suggested an alternative component to the site model; (3) Savannah River C-Area where a characterization report for a waste site within the modeled area was not available to the modelers, but provided significant new information requiring changes to the underlying geologic and hydrogeologic CSM's used; (4) Amargosa Desert Research Site (ADRS) where re-interpretation of resistivity sounding data and water-level data suggested an alternative geologic model. Simple 2-D spreadsheet modeling of the ADRS with the revised CSM provided an improved

  9. A conceptual model of referee efficacy

    Directory of Open Access Journals (Sweden)

    Félix eGuillén


    Full Text Available This paper presents a conceptual model of referee efficacy, defines the concept, proposes sources of referee specific efficacy information, and suggests consequences of having high or low referee efficacy. Referee efficacy is defined as the extent to which referees believe they have the capacity to perform successfully in their job. Referee efficacy beliefs are hypothesized to be influenced by mastery experiences, referee knowledge/education, support from significant others, physical/mental preparedness, environmental comfort, and perceived anxiety. In turn, referee efficacy beliefs are hypothesized to influence referee performance, referee stress, athlete rule violations, athlete satisfaction, and co-referee satisfaction.

X-rays produced by bremsstrahlung are absorbed by a three element copper plate-foam x-ray absorber. Cooling between bursts of electron pulses is provided by pressurized helium.

  11. A conceptual framework for noise reduction

    CERN Document Server

    Benesty, Jacob


    Though noise reduction and speech enhancement problems have been studied for at least five decades, advances in our understanding and the development of reliable algorithms are more important than ever, as they support the design of tailored solutions for clearly defined applications. In this work, the authors propose a conceptual framework that can be applied to the many different aspects of noise reduction, offering a uniform approach to monaural and binaural noise reduction problems, in the time domain and in the frequency domain, and involving a single or multiple microphones. Moreover, the derivation of optimal filters is simplified, as are the performance measures used for their evaluation.

  12. Modalities for an Allegorical Conceptual Data Model

    Directory of Open Access Journals (Sweden)

    Bartosz Zieliński


    Full Text Available Allegories are enriched categories generalizing a category of sets and binary relations. In this paper, we extend a new, recently-introduced conceptual data model based on allegories by adding support for modal operators and developing a modal interpretation of the model in any allegory satisfying certain additional (but natural axioms. The possibility of using different allegories allows us to transparently use alternative logical frameworks, such as fuzzy relations. Mathematically, our work demonstrates how to enrich with modal operators and to give a many world semantics to an abstract algebraic logic framework. We also give some examples of applications of the modal extension.

  13. Conceptual design of a Disk Chopper Spectrometer

    Energy Technology Data Exchange (ETDEWEB)

    Copley, J.R.D. [National Institute of Standards and Technology, Gaithersburg, MD (United States)


    We describe methods that we have used for the conceptual design of the Disk Chopper Spectrometer at the Cold Neutron Research Facility, National Institute of Standards and Technology. Most of the discussion concerns the multiple chopper system. No single design method is best in every situation. We believe that an analytical approach is preferable, whenever possible. Graphical methods of expressing problems have been very instructive. We have also found it useful, and occasionally invaluable, to cross-check results obtained using different methods, such as analytical integration and ray-tracing.

  14. Team building: conceptual, methodological, and applied considerations. (United States)

    Beauchamp, Mark R; McEwan, Desmond; Waldhauser, Katrina J


    Team building has been identified as an important method of improving the psychological climate in which teams operate, as well as overall team functioning. Within the context of sports, team building interventions have consistently been found to result in improvements in team effectiveness. In this paper we review the extant literature on team building in sport, and address a range of conceptual, methodological, and applied considerations that have the potential to advance theory, research, and applied intervention initiatives within the field. This involves expanding the scope of team building strategies that have, to date, primarily focused on developing group cohesion. Copyright © 2017 Elsevier Ltd. All rights reserved.

  15. Caribou co-management: Realizing conceptual differences

    Directory of Open Access Journals (Sweden)

    Anne Kendrick


    Full Text Available The conditions allowing innovative collective learning of the unpredictable dynamics of caribou populations may be particularly apparent in co-management settings, especially those settings that foster diverse understandings of caribou ecology. This paper examines co-management, specifically caribou co-management in arctic and subarctic North America, for evidence of diverse conceptual constructs among co-management participants. It is suggested that the learning occurring in cross-cultural co-management settings may lead to the development of the humility necessary for the expression and adaptation of diverse understandings of caribou ecology.

  17. Topology of the conceptual network of language (United States)

    Motter, Adilson E.; de Moura, Alessandro P.; Lai, Ying-Cheng; Dasgupta, Partha


    We define two words in a language to be connected if they express similar concepts. The network of connections among the many thousands of words that make up a language is important not only for the study of the structure and evolution of languages, but also for cognitive science. We study this issue quantitatively, by mapping out the conceptual network of the English language, with the connections being defined by the entries in a Thesaurus dictionary. We find that this network presents a small-world structure, with an amazingly small average shortest path, and appears to exhibit an asymptotic scale-free feature with algebraic connectivity distribution.

  18. Conceptual foundations and issues in cosmology (United States)

    Sokołowski, Leszek M.


    In these lectures I discuss some fundamental conceptual problems of cosmology, which are usually omitted in the standard courses, though they significantly influence our understanding of the Universe. These include the very notion of the Universe and consequences of its uniqueness, applicability of physical quantities such as distance and velocity in cosmology, the issue of various fine tunings and consequences of that the Universe had its origin in the initial Big Bang singularity. The fundamental features of the Universe were determined soon after the Big Bang and this epoch is hidden under the physics horizon and practically inaccessible to us. Cosmology is disparate from other physical sciences.

  20. Transregionalism: Problems of Terminology and Conceptualization

    Directory of Open Access Journals (Sweden)

    D. A. Kuznetsov


    Full Text Available Today’s world is witnessing the remarkable development of transregional ties between distinct regions and powers within the international system evolving towards multipolarity. However, the essence of transregionalism remains understudied to the extent that there is no clear consensus for which terminology should be used to define this phenomenon. The article compares existing approaches to transregionalism conceptualization, analyzes the differences in the use of terms, and discusses the global impact of transregional relations on world politics and economy. The author advocates a term transregionalism (instead of interregionalism, crossregionalism, macroregionalization etc. and suggests its definition.

  3. The emergence of logistics cities: Conceptual model

    Directory of Open Access Journals (Sweden)

    C. Sengpiehl


    Full Text Available This paper describes the emergence of logistics cities, which are geographical concentrations of related industries situated around one or more international trade gateways adjacent to a metropolitan area. Broadly, a logistics city comprises logistics activities and related assets combined with an integrated mix of manufacturing and assembly companies, business services, retail outlets, research and education centres, and associated government services and administration sections. This concept is currently being promoted and developed globally by several regions, and examples of these logistics cities are described in this paper. Drawing from these examples and the limited available literature, a preliminary conceptual map of the logistics cities concept has been developed which incorporates a theoretical foundation of economic development and the principles of competitiveness in the notion of trade clusters. This map has provided the basis for our further investigations and the continued development of a more detailed conceptual model that will provide a systematic knowledge base for those engaged in the development of further logistics cities. The beneficiaries of this model will be public authorities, property developers and industrial concerns, and will be used when making decisions for future logistics infrastructure, services, supporting services and related social elements.

  4. Conceptual design of inherently safe integral reactor

    Energy Technology Data Exchange (ETDEWEB)

    Kim, J. I.; Chang, M. H.; Lee, D. J. and others


    The design concept of a 300 MWt inherently safe integral reactor(ISIR) for the propulsion of extra large and superhigh speed container ship was developed in this report. The scope and contents of this report are as follows : 1. The state of the art of the technology for ship-mounted reactor 2. Design requirements for ISIR 3. Fuel and core design 4. Conceptual design of fluid system 5. Conceptual design of reactor vessel assembly and primary components 6. Performance analyses and safety analyses. Installation of two ISIRs with total thermal power of 600MWt and efficiency of 21% is capable of generating shaft power of 126,000kW which is sufficient to power a container ship of 8,000TEU with 30knot cruise speed. Larger and speedier ship can be considered by installing 4 ISIRs. Even though the ISIR was developed for ship propulsion, it can be used also for a multi-purpose nuclear power plant for electricity generation, local heating, or seawater desalination by mounting on a movable floating barge.

  5. An Intelligent Tutoring System for Conceptual Physics (United States)

    Franceschetti, Donald R.


    AutoTutor is an intelligent tutoring system (ITS) in which students can learn a variety of subjects through conversation in natural language with a software agent. The agent appears as a face on the screen, with a synthesized voice, and responds to typed input from the student. Student understanding is modeled from student responses, which are matched to high quality essay responses and known misconceptions and bad answers using one of several computational linguistic techniques. With ONR and NSF support a version of AutoTutor covering Newtonian dynamics at the level of Hewitt's Conceptual Physics has been developed and extensively tested. As a byproduct of this work, several thousand student responses to a small number of conceptual physics questions have been collated and mined for misconceptions. Recent work has allowed a comparison of latent semantic analysis and inverse word frequency measures of text match with expert answers. Some results from this process will be presented along with a demonstration of AutoTutor-Physics at work.

  6. Extending Conceptual Schemas with Business Process Information

    Directory of Open Access Journals (Sweden)

    Marco Brambilla


    Full Text Available The specification of business processes is becoming a more and more critical aspect for organizations. Such processes are specified as workflow models expressing the logical precedence among the different business activities (i.e., the units of work. Typically, workflow models are managed through specific subsystems, called workflow management systems, to ensure a consistent behavior of the applications with respect to the organization business process. However, for small organizations and/or simple business processes, the complexity and capabilities of these dedicated workflow engines may be overwhelming. In this paper, we therefore, advocate for a different and lightweight approach, consisting in the integration of the business process specification within the system conceptual schema. We show how a workflow-extended conceptual schema can be automatically obtained, which serves both to enforce the organization business process and to manage all its relevant domain data in a unified way. This extended model can be directly processed with current CASE tools, for instance, to generate an implementation of the system (including its business process in any technological platform.

  7. Conceptual framework for leadership in public service

    Directory of Open Access Journals (Sweden)

    P. O. Haitov


    Full Text Available The article analyzes the conceptual foundations of leadership in the public service. The author comes from the fact that the concept of leadership is a theoretical construct that includes strategy, main directions, objectives and goals of improving public service personnel, to enhance the efficiency of state institutions due to indirect effects of leadership on organizational performance management. According to the author, the concept of leadership in the public service should be a system of coordinated actions which aim not only organizational improvement, but above all to optimize the role of the state, which has not only assist in the implementation of the interests of the population, but also actively participate the formation of civil society. The purpose of the formation and leadership development in the public service is to achieve a new quality vnutryorhanizatsiynoyi interaction that facilitates optimization of power structures as the subject of management and their interaction with the citizens as the object of control. Concept development based on scientific principles, consistency, complexity, individualization, availability. The functional HR service load state body in the direction of leadership. The main provisions defining the conceptual foundations of leadership in the public service, the author highlights: the educational component, regulated by different procedures to change learning within the application of modern methods of active influence on the personality of students to prepare for practice the last management activities; transformation of HR services of state bodies aimed at active inclusion in the formative activities to improve the quality of management interaction subject and object management.

  8. Conceptual Framework To Extend Life Cycle Assessment ... (United States)

    Life Cycle Assessment (LCA) is a decision-making tool that accounts for multiple impacts across the life cycle of a product or service. This paper presents a conceptual framework to integrate human health impact assessment with risk screening approaches to extend LCA to include near-field chemical sources (e.g., those originating from consumer products and building materials) that have traditionally been excluded from LCA. A new generation of rapid human exposure modeling and high-throughput toxicity testing is transforming chemical risk prioritization and provides an opportunity for integration of screening-level risk assessment (RA) with LCA. The combined LCA and RA approach considers environmental impacts of products alongside risks to human health, which is consistent with regulatory frameworks addressing RA within a sustainability mindset. A case study is presented to juxtapose LCA and risk screening approaches for a chemical used in a consumer product. The case study demonstrates how these new risk screening tools can be used to inform toxicity impact estimates in LCA and highlights needs for future research. The framework provides a basis for developing tools and methods to support decision making on the use of chemicals in products. This paper presents a conceptual framework for including near-field exposures into Life Cycle Assessment using advanced human exposure modeling and high-throughput tools

  9. Harmonising Nursing Terminologies Using a Conceptual Framework. (United States)

    Jansen, Kay; Kim, Tae Youn; Coenen, Amy; Saba, Virginia; Hardiker, Nicholas


    The International Classification for Nursing Practice (ICNP®) and the Clinical Care Classification (CCC) System are standardised nursing terminologies that identify discrete elements of nursing practice, including nursing diagnoses, interventions, and outcomes. While CCC uses a conceptual framework or model with 21 Care Components to classify these elements, ICNP, built on a formal Web Ontology Language (OWL) description logic foundation, uses a logical hierarchical framework that is useful for computing and maintenance of ICNP. Since the logical framework of ICNP may not always align with the needs of nursing practice, an informal framework may be a more useful organisational tool to represent nursing content. The purpose of this study was to classify ICNP nursing diagnoses using the 21 Care Components of the CCC as a conceptual framework to facilitate usability and inter-operability of nursing diagnoses in electronic health records. Findings resulted in all 521 ICNP diagnoses being assigned to one of the 21 CCC Care Components. Further research is needed to validate the resulting product of this study with practitioners and develop recommendations for improvement of both terminologies.

  10. Metáfora y estructura conceptual

    Directory of Open Access Journals (Sweden)

    Emilia Castaño


    Full Text Available La lingüística cognitiva siempre ha argumentado que la metáfora no pertenece exclusivamente al lenguaje, sino que es una competencia que se basa en la habilidad humana de concebir un dominio de experiencia en términos de otro. Entendida así, la metáfora no puede ser otra cosa que un fenómeno conceptual. No obstante, pocos adeptos de la lingüística cognitiva han concentrados sus esfuerzos en catalogar manifestaciones metafóricas en ámbitos no lingüísticos. En este trabajo, sugerimos que es factible encontrar pruebas de que la metáfora es un proceso conceptual y, como tal, se manifiesta en esferas que no son estrictamente lingüísticas. Para ello, aportamos un seguido de evidencias muy diversas, como por ejemplo su papel en el razonamiento lógico-matemático de los niños en la fase preoperacional del desarrollo cognitivo, la programación de interfaces para aplicaciones informáticas y los resultados de tres estudios empíricos realizados recientemente en el campo  de la psicología cognitiva que analizan los efectos whorfianos en la conceptualización del tiempo y los efectos del espacio en la memoria emocional.

  11. Historical trauma: politics of a conceptual framework. (United States)

    Prussing, Erica


    The concept of historical trauma (HT) is compelling: Colonialism has set forth cumulative cycles of adversity that promote morbidity and mortality at personal and collective levels, with especially strong mental health impacts. Yet as ongoing community-based as well as scholarly discussions attest, lingering questions continue to surround HT as a framework for understanding the relationships between colonialism and indigenous mental health. Through an overview of 30 recent peer-reviewed publications that aim to clarify, define, measure, and interpret how HT impacts American Indian and Alaska Native (AIAN) mental health, this paper examines how the conceptual framework of HT has circulated in ways shaped by interactions among three prominent research approaches: evidence-based, culturally relevant, and decolonizing. All define current approaches to AIAN mental health research, but each sets forth different conceptualizations of the connections between colonialism and psychological distress. The unfolding trajectory of research about HT reflects persistent tensions in how these frameworks interact, but also possibilities for better integrating them. These considerations aim to advance conversations about the politics of producing knowledge about AIAN mental health, and support ongoing calls for greater political pluralism in mental health research. © The Author(s) 2014 Reprints and permissions:

  12. Conceptual problem solving in high school physics

    Directory of Open Access Journals (Sweden)

    Jennifer L. Docktor


    Full Text Available Problem solving is a critical element of learning physics. However, traditional instruction often emphasizes the quantitative aspects of problem solving such as equations and mathematical procedures rather than qualitative analysis for selecting appropriate concepts and principles. This study describes the development and evaluation of an instructional approach called Conceptual Problem Solving (CPS which guides students to identify principles, justify their use, and plan their solution in writing before solving a problem. The CPS approach was implemented by high school physics teachers at three schools for major theorems and conservation laws in mechanics and CPS-taught classes were compared to control classes taught using traditional problem solving methods. Information about the teachers’ implementation of the approach was gathered from classroom observations and interviews, and the effectiveness of the approach was evaluated from a series of written assessments. Results indicated that teachers found CPS easy to integrate into their curricula, students engaged in classroom discussions and produced problem solutions of a higher quality than before, and students scored higher on conceptual and problem solving measures.

  13. Conceptual Model of Dynamic Geographic Environment

    Directory of Open Access Journals (Sweden)

    Martínez-Rosales Miguel Alejandro


    Full Text Available In geographic environments, there are many and different types of geographic entities such as automobiles, trees, persons, buildings, storms, hurricanes, etc. These entities can be classified into two groups: geographic objects and geographic phenomena. By its nature, a geographic environment is dynamic, thus, it’s static modeling is not sufficient. Considering the dynamics of geographic environment, a new type of geographic entity called event is introduced. The primary target is a modeling of geographic environment as an event sequence, because in this case the semantic relations are much richer than in the case of static modeling. In this work, the conceptualization of this model is proposed. It is based on the idea to process each entity apart instead of processing the environment as a whole. After that, the so called history of each entity and its spatial relations to other entities are defined to describe the whole environment. The main goal is to model systems at a conceptual level that make use of spatial and temporal information, so that later it can serve as the semantic engine for such systems.

  14. Cognitive neuropsychiatry: conceptual, methodological and philosophical perspectives. (United States)

    Hohwy, Jakob; Rosenberg, Raben


    Cognitive neuropsychiatry attempts to understand psychiatric disorders as disturbances to the normal function of human cognitive organisation, and it attempts to link this functional framework to relevant brain structures and their pathology. This recent scientific discipline is the natural extension of cognitive neuroscience into the domain of psychiatry. We present two examples of recent research in cognitive neuropsychiatry: delusions of control in schizophrenia, and affective disorders. The examples demonstrate how the cognitive approach is a fruitful and necessary supplement to the otherwise successful biological psychiatry paradigm, which tend to bypass the cognitive level. Philosophy concerns some of the core concepts involved in psychiatric illness, particularly concerning rationality, thought and action, reality testing, and the self. We present concrete examples that illustrate how philosophical conceptual tools can be particularly important for the construction and interpretation of the cognitive models relevant to the understanding of psychiatric illness. We conclude that cognitive neuropsychiatry is a fruitful and necessary supplement to biological psychiatry. Furthermore, cognitive neuropsychiatry itself may benefit significantly from employing philosophical conceptual tools in the interpretation and construction of its cognitive models. The cognitive and philosophical approaches may thus be further steps towards a scientific psychopathology.

  20. Conceptual fluency increases recollection: behavioral and electrophysiological evidence. (United States)

    Wang, Wei; Li, Bingbing; Gao, Chuanji; Xu, Huifang; Guo, Chunyan


    It is widely established that fluency can contribute to recognition memory. Previous studies have found that enhanced fluency increases familiarity, but not recollection. The present study was motivated by a previous finding that conceptual priming affected recollection. We used event-related potentials to investigate the electrophysiological correlates of these effects with conceptually related two-character Chinese words. We found that previous conceptual priming effects on conceptual fluency only increased the incidence of recollection responses. We also found that enhanced conceptual fluency was associated with N400 attenuation, which was also correlated with the behavioral indicator of recollection. These results suggest that the N400 effect might be related to the impact of conceptual fluency on recollection recognition. These study findings provide further evidence for the relationship between fluency and recollection.

    In view of the ITER conceptual design review, the design of the ancillary systems of the European test blanket systems presented in [1] has been updated and made consistent with the ITER requirements for the present design phase. Europe is developing two concepts of TBM, the helium cooled lithium lead (HCLL) and the helium cooled pebble bed (HCPB) one, having in common the cooling media, pressurized helium at 8 MPa [2]. TBS, namely helium cooling system (HCS), coolant purification system (CPS), lead lithium loop and tritium extraction/removal system (TES–TRS) have the purpose to cool down the TBM and to remove tritium to be driven to TEP from breeder and coolant. These systems are placed in port cell 16 (PC#16), chemical and volume control system (CVCS) area and tritium building. Starting from the pre-conceptual design developed in the past, more mature technical interfaces with the ITER facility have been consolidated and iterative design activities were performed to comply with design requirements/specifications requested by IO to conclude the conceptual design phase. In this paper the present status of design of the TBS is presented together with the preliminary integration in ITER areas.

  3. Using a shoe as a plant pot: neural correlates of passive conceptual expansion. (United States)

    Kröger, Sören; Rutter, Barbara; Stark, Rudolf; Windmann, Sabine; Hermann, Christiane; Abraham, Anna


    Conceptual expansion is a key process that underlies our ability to think creatively. In the present event-related fMRI study, a modified Alternate Uses Task was used to identify brain regions involved during passive conceptual expansion and thereby separately assess the effects of the two defining elements of creative output: Originality (unusualness) and Relevance (appropriateness). Participants viewed word pairs consisting of an object and a use and indicated whether the given use was unusual and/or appropriate for the given object. Trials with object-use combinations judged as unusual and appropriate (HUHA) were contrasted against trials judged as just unusual but inappropriate (HULA) or just appropriate but not unusual (LUHA). As hypothesized, conceptual expansion related activation (HUHA) was found in the bilateral inferior frontal gyrus (BA 45, 47), left temporal pole (BA 38) and left frontopolar cortex (BA 10). We discuss the specific contributions of these regions with reference to semantic cognition. Copyright © 2011 Elsevier B.V. All rights reserved.

  4. Optimal combinations of specialized conceptual hydrological models (United States)

    Kayastha, Nagendra; Lal Shrestha, Durga; Solomatine, Dimitri


    In hydrological modelling it is a usual practice to use a single lumped conceptual model for hydrological simulations at all regimes. However often the simplicity of the modelling paradigm leads to errors in represent all the complexity of the physical processes in the catchment. A solution could be to model various hydrological processes separately by differently parameterized models, and to combine them. Different hydrological models have varying performance in reproducing catchment response. Generally it cannot be represented precisely in different segments of the hydrograph: some models performed well in simulating the peak flows, while others do well in capturing the low flows. Better performance can be achieved if a model being applied to the catchment using different model parameters that are calibrated using criteria favoring high or low flows. In this work we use a modular approach to simulate hydrology of a catchment, wherein multiple models are applied to replicate the catchment responses and each "specialist" model is calibrated according to a specific objective function which is chosen in a way that forces the model to capture certain aspects of the hydrograph, and outputs of models are combined using so-called "fuzzy committee". Such multi-model approach has been already previously implemented in the development of data driven and conceptual models (Fenicia et al., 2007), but its perfomance was considered only during the calibration period. In this study we tested an application to conceptual models in both calibration and verification period. In addition, we tested the sensitivity of the result to the use of different weightings used in the objective functions formulations, and memberbship functions used in the committee. The study was carried out for Bagamati catchment in Nepal and Brue catchment in United Kingdoms with the MATLAB-based implementation of HBV model. Multi-objective evolutionary optimization genetic algorithm (Deb, 2001) was used to

  5. Structural analysis at aircraft conceptual design stage (United States)

    Mansouri, Reza

    . Considering the strength and limitations of both methodologies, the question to be answered in this thesis is: How valuable and compatible are the classical analytical methods in today's conceptual design environment? And can these methods complement each other? To answer these questions, this thesis investigates the pros and cons of classical analytical structural analysis methods during the conceptual design stage through the following objectives: Illustrate structural design methodology of these methods within the framework of Aerospace Vehicle Design (AVD) lab's design lifecycle. Demonstrate the effectiveness of moment distribution method through four case studies. This will be done by considering and evaluating the strength and limitation of these methods. In order to objectively quantify the limitation and capabilities of the analytical method at the conceptual design stage, each case study becomes more complex than the one before.

  9. Conceptual similarity promotes generalization of higher order fear learning (United States)

    Dunsmoor, Joseph E.; White, Allison J.; LaBar, Kevin S.


    We tested the hypothesis that conceptual similarity promotes generalization of conditioned fear. Using a sensory preconditioning procedure, three groups of subjects learned an association between two cues that were conceptually similar, unrelated, or mismatched. Next, one of the cues was paired with a shock. The other cue was then reintroduced to test for fear generalization, as measured by the skin conductance response. Results showed enhanced fear generalization that correlated with trait anxiety levels in the group that learned an association between conceptually similar stimuli. These findings suggest that conceptual representations of conditional stimuli influence human fear learning processes. PMID:21330378

  14. Conceptual Fuselage Design with Direct CAD Modeling (United States)

    Anderson, Benjamin K.

    In today's day and age, the use of automated technology is becoming increasingly prevalent. Throughout the aerospace industry, we see the use of automated systems in manufacturing, testing, and, progressively, in design. This thesis focuses on the idea of automated structural design that can be directly coupled with parametric Computer-Aided Drafting (CAD) and used to support aircraft conceptual design. This idea has been around for many years; however, with the advancement of CAD technology, it is becoming more realistic. Having the ability to input design parameters, analyze the structure, and produce a basic CAD model not only saves time in the design process but provides an excellent platform to communicate ideas. The user has the ability to change parameters and quickly determine the effect on the structure. Coupling this idea with automated parametric CAD provides visual verification and a platform to export into Finite Element Analysis (FEA) for further verification.

  15. Conceptual assessment tool for advanced undergraduate electrodynamics (United States)

    Baily, Charles; Ryan, Qing X.; Astolfi, Cecilia; Pollock, Steven J.


    As part of ongoing investigations into student learning in advanced undergraduate courses, we have developed a conceptual assessment tool for upper-division electrodynamics (E&M II): the Colorado UppeR-division ElectrodyNamics Test (CURrENT). This is a free response, postinstruction diagnostic with 6 multipart questions, an optional 3-question preinstruction test, and accompanying grading rubrics. The instrument's development was guided by faculty-consensus learning goals and research into common student difficulties. It can be used to gauge the effectiveness of transformed pedagogy, and to gain insights into student thinking in the covered topic areas. We present baseline data representing 500 students across 9 institutions, along with validity, reliability, and discrimination measures of the instrument and scoring rubric.

  16. Conceptual Aspects of Gauge/Gravity Duality (United States)

    De Haro, Sebastian; Mayerson, Daniel R.; Butterfield, Jeremy N.


    We give an introductory review of gauge/gravity duality, and associated ideas of holography, emphasising the conceptual aspects. The opening sections gather the ingredients, viz. anti-de Sitter spacetime, conformal field theory and string theory, that we need for presenting, in Sect. 5, the central and original example: Maldacena's AdS/CFT correspondence. Sections 6 and 7 develop the ideas of this example, also in applications to condensed matter systems, QCD, and hydrodynamics. Sections 8 and 9 discuss the possible extensions of holographic ideas to de Sitter spacetime and to black holes. Section 10 discusses the bearing of gauge/gravity duality on two philosophical topics: the equivalence of physical theories, and the idea that spacetime, or some features of it, are emergent.

  17. A Conceptual Framework for Integrated Pest Management. (United States)

    Stenberg, Johan A


    The concept of integrated pest management (IPM) has been accepted and incorporated in public policies and regulations in the European Union and elsewhere, but a holistic science of IPM has not yet been developed. Hence, current IPM programs may often be considerably less efficient than the sum of separately applied individual crop protection actions. Thus, there is a clear need to formulate general principles for synergistically combining traditional and novel IPM actions to improve efforts to optimize plant protection solutions. This paper addresses this need by presenting a conceptual framework for a modern science of IPM. The framework may assist attempts to realize the full potential of IPM and reduce risks of deficiencies in the implementation of new policies and regulations. Copyright © 2017 The Author(s).

  19. Conceptual design of a spaceborne lightning sensor (United States)

    Wolfe, W. L.; Nagler, M.


    A conceptual design of a broad-area optical lightning telescope sensor (BOLTS) designed to provide full-time (day/night) coverage of the continental United States from a geosynchronous orbit is described. Variations are discussed that could cover the whole globe from four to five geosynchronous satellites or cover only smaller areas with a high (2.5 km) resolution. The design is based on research results of the initial phase of a NASA-sponsored program. The ground resolution will be 8 x 8 km. The focal plane is an 800 x 800 pixel CCD array, electronically subdivided to allow for the high data rates (1000 frames per sec) imposed by the characteristics of lightning flashes. It will detect lightning strokes whose optical power is greater than 10 million watts, with a probability of detection of 0.9, and a false alarm rate of 0.1.

  20. Geographical conceptualization of quality of life

    Directory of Open Access Journals (Sweden)

    Murgaš František


    Full Text Available The conceptualization of quality of life in terms of geography is based on two assumptions. The first assumption is that the quality of life consists of two dimensions: subjective and objective. The subjective is known as ‘well-being’, while the objective is the proposed term ‘quality of place’. The second assumption is based on the recognition that quality of life is always a spatial dimension. The concept of quality of life is closely linked with the concept of a good life; geographers enriched this concept by using the term ‘good place’ as a place in which the conditions are created for a good life. The quality of life for individuals in terms of a good place overlaps with the quality of life in society, namely the societal quality of life. The geographical conceptualisation of quality of life is applied to settlements within the city of Liberec.

  2. Evaluation of Students' Conceptual Understanding of Malaria (United States)

    Poh-Ai Cheong, Irene; Treagust, David; Kyeleve, Iorhemen J.; Oh, Peck-Yoke


    In this study, a two-tier diagnostic test for understanding malaria was developed and administered to 314 Bruneian students in Year 12 and in a nursing diploma course. The validity, reliability, difficulty level, discriminant indices, and reading ability of the test were examined and found to be acceptable in terms of measuring students' understanding and identifying alternative conceptions with respect to malaria. Results showed that students' understanding of malaria was high for content, low for reasons, and limited and superficial for both content and reasons. The instrument revealed several common alternative conceptual understandings students' hold about malaria. The MalariaTT2 instrument developed could be used in classroom lessons for challenging alternative conceptions and enhancing conceptions of malaria.

  7. Global Journalism Ethics: Widening the Conceptual Base

    Directory of Open Access Journals (Sweden)

    Stephen J. A. Ward


    Full Text Available For most of its history, journalism ethics has been highly practical in aim, in theorizing, and in application. Inquiry analyzed what was occurring inside newsrooms and its scope was parochial. Starting from the premise that a parochial approach no longer serves journalism, the study of journalism, or the public of journalism, in this paper it is argued that a major task of journalism ethics is to construct a more non-parochial ethics—a global journalism ethics informed by critical work from various disciplines and cultures. The discussion presented charts the trajectory of journalism ethics over several centuries to explain the role of parochialism and the limits of theorizing in journalism ethics. This historical perspective also serves as a foundation for outlining what a future journalism ethics might look like, if we widen the conceptual base by incorporating new knowledge of media from outside journalism ethics, and by redefining journalism ethics as a global enterprise.

  8. On the conceptual foundations of psychological measurement (United States)

    Maul, Andrew; Wilson, Mark; Torres Irribarra, David


    Measurement has long been an important element of epistemology in the physical sciences and natural philosophy. More recently, the psychological sciences have developed a variety of techniques that purport to be instances of measurement as well. However, it is not clear how the understanding of measurement invoked in psychological science applications accords with the understanding of measurement found in other scientific disciplines. A sharper focus on conceptual clarity and coherence across the psychological and physical sciences has the potential to add a great deal to efforts to improve such practices. In this paper, we argue that it is possible to formulate a philosophically coherent account of how measurement works in both the physical and the human sciences.

    Full Text Available The literature review indicates that the benefit of screencast as an instructional media has not clearly proved effective for all categories of students. This is due to the individual differences in processing the information. Inadequate screencast design will cause strain to students’ cognitive process which might impede learning. This shortcoming can be reduced by imposing principles of reducing the external processing in screencast design. However, the exact design effectiveness of screencast also depends on the cognitive style and learning style of the students. The cognitive style will ultimately affect how information is processed in the students’ memory structure. Students will also easily process the given information, if it is performed in accordance with their dominant learning style. Taken together, this article discusses the conceptual framework design of screencasts for instructional purpose.

  10. Towards a conceptualization of the translator's legacy

    Directory of Open Access Journals (Sweden)

    Guzmán María Constanza


    Full Text Available This article investigates ways of theorizing the figure of the translator and its legacy within translation studies. It focuses on contemporary theoretical approaches, largely drawn from poststructuralist perspectives, which find the question of the translating subject to be a crucial one for translation and literary studies and propose important ways to approach it. It interrogates notions such as the idea of the sacralized original, the relationship between authorship and property, the ideal of transparent meaning, and the tension between translation and original writing. Particular attention is given to the importance of historicizing the translator's practice, recognizing the translator as a visible agent, and conceptualizing translation as a form of writing that unfolds within complex interactions and negotiations.

  11. Conceptual design of rotary magnetostrictive energy harvester (United States)

    Park, Young-Woo; Kang, Han-Sam; Wereley, Norman M.


    This paper presents the conceptual design of a rotary magnetostrictive energy harvester (RMEH), which consists of one coil-wound Galfenol cantilever, with two PMs adhered onto the each end, and one permanent magnet (PM) array sandwiched between two wheels. Modeling and simulation are used to validate the concept. The proof-of-concept RMEH is fabricated by using the simulation results, and subjected to the experimental characterization. The experimental setup for the simulated characterization uses the motor-driven PM array to induce a forced vibration. It can be concluded that the theoretical prediction on the induced voltage agrees well with the experimental results and that induced voltage increases with rpm and with number of PMs. Future work includes optimization of RMEH performance via PM array configuration and development of prototype.

  12. Electrometric sensors for neutron radiation: conceptual study (United States)

    Bogolubov, E.; Koshelev, A.; Mikerov, V.; Sviridov, A.


    The paper considers main issues related to the conceptual development of neutron electrometric sensors based on charge uploading. The performance capabilities of sensors such as the detection threshold, dynamic range and sensitivity to gamma radiation were estimated for theoretically feasible designs. The designs do not contain radioactive materials, have no limitations on the fluence and the neutron flux density, can measure the time dependence of the neutron yield, can be low-sensitive to electromagnetic noise. They have a simple structure and some designs do not require the external power supply. Such sensors can be used in the control systems of nuclear reactors and subcritical assemblies, in measurements of the neutron yield of pulsed sources and in scientific investigations.

  14. Supernatural beliefs, natural kinds, and conceptual structure. (United States)

    Walker, S J


    This article presents cross-cultural evidence in support of the notion that adults' natural kind concepts are theory based but may be informed by knowledge/belief systems other than the biological. Three groups of subjects from western Nigeria--rural, urban, and elite--participated in the study. Subjects heard stories describing alterations of appearance; that is, one natural kind was made to resemble another in both ritual and nonritual contexts. Subjects then were required to judge the identity of the altered item and to give an explanation for the category judgment. It was predicted that subjects would make more nonpreservation-of-identity category judgments supported by supernatural explanations in the ritual contexts and that subjects' use of supernatural explanations would reflect the extent of their engagement with the supernatural. The first prediction was borne out; the second prediction was only partially supported. Discussion of the results emphasizes the importance of exploring the role of sociocultural factors in conceptual structure.

  15. A Conceptual Framework for Circular Design

    Directory of Open Access Journals (Sweden)

    Mariale Moreno


    Full Text Available Design has been recognised in the literature as a catalyst to move away from the traditional model of take-make-dispose to achieve a more restorative, regenerative and circular economy. As such, for a circular economy to thrive, products need to be designed for closed loops, as well as be adapted to generate revenues. This should not only be at the point of purchase, but also during use, and be supported by low-cost return chains and reprocessing structures, as well as effective policy and regulation. To date, most academic and grey literature on the circular economy has focused primarily on the development of new business models, with some of the latter studies addressing design strategies for a circular economy, specifically in the area of resource cycles and design for product life extension. However, these studies primarily consider a limited spectrum of the technical and biological cycles where materials are recovered and restored and nutrients (e.g., materials, energy, water are regenerated. This provides little guidance or clarity for designers wishing to design for new circular business models in practice. As such, this paper aims to address this gap by systematically analysing previous literature on Design for Sustainability (DfX (e.g., design for resource conservation, design for slowing resource loops and whole systems design and links these approaches to the current literature on circular business models. A conceptual framework is developed for circular economy design strategies. From this conceptual framework, recommendations are made to enable designers to fully consider the holistic implications for design within a circular economy.

  16. The conceptual model of DFD-technology

    Georgiy N. Kalyanov


    Full Text Available The presence of large number of models and methods for structural modeling of business processes and systems has made urgent the development of standardized language for structural analysis and design, suitable for modeling as organizational management, and software systems (similar to UML for the object-oriented systems’ design.The paper proposes a draft of such a language based on data flow diagrams (DFD diagrams as the most frequently used in functional structural modeling.As part of the work in this direction a conceptual model language is proposed, named DFD-technology, integrating structural models for different purposes based on DFD-diagrams, and reflecting functional, informational and behavioral aspects of the modeled object.The article also analyzes the syntax, semantic and pragmatic aspects of the introduced unified modeling language.For a formal description of the syntax, it is proposed to use the apparatus of the mixed grammars, a combination of graph and regular grammars. The article gives a grammar description to generate a simple dialect of DFD technology, informally described semantic aspects of language, particularly the semantics of relations between objects of the language.Thus, the paper proposed a solution of unification and standardization problem of structural modeling languages, based on the integrated DFD-technology. The conceptual model of the technology is prepared, the syntax of the standardized language, using the technique of the mixed grammar and the semantic aspects of the language are described in detail.It should be noted that the proposed methods in the article and models occupy the central place in modern business processes theory.

  17. Conceptual design report for site drainage control

    Energy Technology Data Exchange (ETDEWEB)

    Hunter, M.R.


    The Mound Plant (Mound), located in Miamisburg, Ohio, is a Department of Energy (DOE) development and production facility performing support work for DOE`s weapons and energy-related programs. EG&G Mound Applied Technologies, Inc. (EG&G) is the Operating Contractor (OC) for this Government-Owned, Contractor-Operated (GOCO) facility. The work performed at Mound emphasizes nuclear energy and explosives technology. Mound is currently implementing an Environmental, Safety & Health (ES&H) Upgrades Program designed to protect its employees, the public, and the environment from adverse effects caused by facility activities. The first project of this multiphase program is now in the final stages of construction, and the second project is currently under design. Four additional projects, one of which is presented in this report, are in the conceptual design stage. At Mound, 22 soil zones have become contaminated with radioactive material. These zones cover approximately 20 percent of the total area of developed property at the site. During a storm event, the rainwater washes contaminated soil from these zones into the storm sewer system. These radioactive contaminants may then be discharged along with the stormwater into the Great Miami River via the Miami Erie Canal. This conceptual design report (CDR), Site Drainage Control, the fourth project in the ES&H program, describes a project that will provide improvements and much needed repairs to inadequate and deteriorating portions of the storm drainage system on the developed property. The project also will provide a stormwater retention facility capable of storing the stormwater runoff, from the developed property, resulting from a 100-year storm event. These improvements will permit the effective control and monitoring of stormwater to prevent the spread of radioactive contaminants from contaminated soil zones and will provide a means to collect and contain accidental spills of hazardous substances.

    Full Text Available This article presents a literature review on problem solving in Physics based on the scientific articles published in periodicals of the related field of study. The articles considered for this study were published in the period between the end of the 70`s until 1999. A categorization of the publications , according to the issue investigated, the theoretical background used, the research method adopted, the results and conclusions are considered as a starting point in order to present a research profile of the field of study. Next, this profile is discussed and analyzed , pointing out the convergent aspects that characterize the field. Taking this analysis into account, the following thesis (based on Fávero`s proposal, 2000 is defended: in order to generate tools for the teaching practice of Physics through the study of problem solving, a method that substitutes the idea of knowledge transmission in the communication processes that takes place in the classroom should be developed. This method should comprise the idea of interlocution (Vion, 2000 which focuses on social interaction as a means to reveal metacognitive regulations of the subjects, pariticipants in the process, and their development of awareness in relation to a conceptual field (Vergnaud, 1990 – Physics, in this case. The analysis of these processes considers the verbal exchanges among the subjects (Bromberg & Chabrol, 1999 developed in the situation of interaction. This thesis is supported by the articulation of concepts in Psychology, including its interface with linguistics, such as conceptual field, development of awareness and acts of speech, which are reconsidered in this study.

  19. Conceptual Learning: Enhancing Student Understanding of Physiology (United States)

    Waltz, Micah J.

    Students are leaving undergraduate science programs without the knowledge and skills they are expected to have. This is apparent in professional programs, such as medical and veterinary school, where students do not possess the critical thinking skills necessary to be successful. Physiology is a required discipline for these professional programs and often before, as a pre-requisite. Physiology classrooms are an excellent place to teach critical thinking skills because the content consists of integrated processes. Therefore, in one study, it was investigated whether focusing on physiological concepts improved student understanding of physiology in both a non-physiological science course, Invertebrate Zoology, and in an undergraduate physiology course. An educational intervention was used in Invertebrate Zoology, where students were exposed to human physiology concepts that were similar to comparative physiology concepts they had learned during the semester. A pre-/post-test was used to assess learning gains. In a second study, the use of multimedia file usage was correlated to student exam scores in a physiology course. This was done to see if providing additional study materials that focused on specific concepts improved student understanding, as assessed using exam scores. Overall these studies indicate that encouraging assimilation of new concepts that expand upon material from lecture may help students gain a more complete understanding of a concept. The integration of these concepts into pre-existing conceptual frameworks may serve to teach students valuable critical thinking skills such as evaluation of new ideas within their current understanding and synthesizing the new content with the existing information. Focusing on this type of conceptual learning may enable students to apply content knowledge and think through problems. Additionally, focusing on concepts may enable students to improve their understanding of material without being overwhelmed by

  20. Consumers' conceptualization of ultra-processed foods. (United States)

    Ares, Gastón; Vidal, Leticia; Allegue, Gimena; Giménez, Ana; Bandeira, Elisa; Moratorio, Ximena; Molina, Verónika; Curutchet, María Rosa


    Consumption of ultra-processed foods has been associated with low diet quality, obesity and other non-communicable diseases. This situation makes it necessary to develop educational campaigns to discourage consumers from substituting meals based on unprocessed or minimally processed foods by ultra-processed foods. In this context, the aim of the present work was to investigate how consumers conceptualize the term ultra-processed foods and to evaluate if the foods they perceive as ultra-processed are in concordance with the products included in the NOVA classification system. An online study was carried out with 2381 participants. They were asked to explain what they understood by ultra-processed foods and to list foods that can be considered ultra-processed. Responses were analysed using inductive coding. The great majority of the participants was able to provide an explanation of what ultra-processed foods are, which was similar to the definition described in the literature. Most of the participants described ultra-processed foods as highly processed products that usually contain additives and other artificial ingredients, stressing that they have low nutritional quality and are unhealthful. The most relevant products for consumers' conceptualization of the term were in agreement with the NOVA classification system and included processed meats, soft drinks, snacks, burgers, powdered and packaged soups and noodles. However, some of the participants perceived processed foods, culinary ingredients and even some minimally processed foods as ultra-processed. This suggests that in order to accurately convey their message, educational campaigns aimed at discouraging consumers from consuming ultra-processed foods should include a clear definition of the term and describe some of their specific characteristics, such as the type of ingredients included in their formulation and their nutritional composition.

  1. Development of a conceptual framework of health-related quality of life in pressure ulcers: a patient-focused approach. (United States)

    Gorecki, Claudia; Lamping, Donna L; Brown, Julia M; Madill, Anna; Firth, Jill; Nixon, Jane


    Evaluating outcomes such as health-related quality of life is particularly important and relevant in skin conditions such as pressure ulcers where the condition and associated interventions pose substantial burden to patients. Measures to evaluate such outcomes need to be developed by utilising patient-perspective to ensure that content and conceptualisation is relevant to patients. Our aim was to develop a conceptual framework of health-related quality of life in pressure ulcers, based on patients' views about the impact of pressure ulcers and interventions on health-related quality of life to inform the development of a new patient-reported outcome measure. SETTING, PARTICIPANTS AND METHODS: We developed a working conceptual framework based on a previous review of the literature, then used semi-structured qualitative interviews with 30 adults with pressure ulcers (22-94 years) purposively sampled from hospital, community and rehabilitation care settings in England and Northern Ireland to obtain patients' views, and thematic content analysis and review by a multidisciplinary expert group to develop the final conceptual framework. Our conceptual model includes four health-related quality of life domains (symptoms, physical functioning, psychological well-being, social functioning), divided into 13 sub-domains and defined by specific descriptive components. We have identified health-related quality of life outcomes that are important to people with pressure ulcers and developed a conceptual framework using robust and systematic methods, which provides the basis for the development of a new pressure ulcer-specific measure of health-related quality of life.

  2. Patient-centred care is a way of doing things: How healthcare employees conceptualize patient-centred care. (United States)

    Fix, Gemmae M; VanDeusen Lukas, Carol; Bolton, Rendelle E; Hill, Jennifer N; Mueller, Nora; LaVela, Sherri L; Bokhour, Barbara G


    Patient-centred care is now ubiquitous in health services research, and healthcare systems are moving ahead with patient-centred care implementation. Yet, little is known about how healthcare employees, charged with implementing patient-centred care, conceptualize what they are implementing. To examine how hospital employees conceptualize patient-centred care. We conducted qualitative interviews about patient-centred care during site four visits, from January to April 2013. We interviewed 107 employees, including leadership, middle managers, front line providers and staff at four US Veteran Health Administration (VHA) medical centres leading VHA's patient-centred care transformation. Data were analysed using grounded thematic analysis. Findings were then mapped to established patient-centred care constructs identified in the literature: taking a biopsychosocial perspective; viewing the patient-as-person; sharing power and responsibility; establishing a therapeutic alliance; and viewing the doctor-as-person. We identified three distinct conceptualizations: (i) those that were well aligned with established patient-centred care constructs surrounding the clinical encounter; (ii) others that extended conceptualizations of patient-centred care into the organizational culture, encompassing the entire patient-experience; and (iii) still others that were poorly aligned with patient-centred care constructs, reflecting more traditional patient care practices. Patient-centred care ideals have permeated into healthcare systems. Additionally, patient-centred care has been expanded to encompass a cultural shift in care delivery, beginning with patients' experiences entering a facility. However, some healthcare employees, namely leadership, see patient-centred care so broadly, it encompasses on-going hospital initiatives, while others consider patient-centred care as inherent to specific positions. These latter conceptualizations risk undermining patient-centred care

  3. Social systems in terms of coherent individual neurodynamics: conceptual premises, experimental and simulation scope (United States)

    Plikynas, Darius; Basinskas, Gytis; Kumar, Pravin; Masteika, Saulius; Kezys, Darius; Laukaitis, Algirdas


    After reviewing numerous theories and experiments, our research adopted the field-theoretical deductive approach to shed new light on complex social systems as coherent neurodynamic processes taking place in individual minds. In this interdisciplinary study, we have outlined some general fundamental design principles of the field-theoretical view of the oscillating agent as well as of coherent social systems. From the systems point of view, ordered social systems by their own intrinsic nature are interpreted as coherent activations via the mind-field medium of social agents. Consequently, this study not only provides the major conceptual assumptions of the proposed (Oscillation-Based Multi-Agent System [OSIMAS]) paradigm but also presents an electroencephalography-based inductive experimental validation framework and some empirical results to validate major OSIMAS assumptions. Based on the conceptual and experimental findings, we constructed modelling framework and presented oscillations-based micro (coupled oscillator energy exchange model) and macro (MEPSM1) simulation models. We also systemized some other studies and applications, which are most relevant to the work presented here.

  4. Conceptual development as rising from the abstract to the concrete: from thought energy to experienced energy

    Directory of Open Access Journals (Sweden)

    Rodrigo dos Santos Crepalde


    Full Text Available The development of scientific concepts is usually described as a pathway from the realm of concrete life to the abstract principles of science, in a higher level of generalisation. In this paper, we argue that the appropriation of scientific concepts occurs in the return to concrete in a higher level of conceptual development, which means a transition from the given concrete to a thoughtful and recreated concrete. In the first part of the paper we ground this point of view based on the intellectual routes of Lev Vigotski and on the Philosophy of Language of Michail Bakhtin. From Vigotski, we discuss the dialectic method of research, the concept of semiotic mediation and its implications to conceptual development, the relationship between everyday and scientific concepts and the role of concrete and abstract realms in conceptual development. From Bakhtin, we understand conceptual development as sense making in the dialogue between voices in different spheres of social life. In the second part of this paper we present empirical evidence to support this thesis. This will be done by analysing the meanings evoked by rural teacher students to the concept of energy in narratives produced by them at the end of a module of study on this subject. We seek to examine how the subjects of this experience populate with new meanings, dialectically and dialogically, the concept of energy. The main result of this study is the presence of a hybridisation of scientific and everyday life discourses in the efforts of subjects to confer relevant meanings (in both personal and social aspects to the abstract statements of science. We conclude with some implications of this thesis to science education research and practice.

  5. Power. Conflicting views. (United States)

    Heineken, J


    This study on power is the first of its kind reported in the nursing literature. We now know that the term "power" has significantly different meanings for nurses. The basic differences found between nurse executives and head and charge nurses with respect to their views on power is a timely finding. Before generalizations and interventions can be definitively suggested, more studies must be done. Nurses interested in participating in this effort should contact the author. The issue of unification of nurses is important. More exploration in the area of power will bring us closer to mobilizing our potential and strength. Nurse executives will be more successful in accomplishing their organizational goals with a united personnel group. The discrepancy in power beliefs identified in this article will create the stimulus for further discussion and reflection.

  6. A New Conceptualization of Human Visual Sensory-Memory (United States)

    Öğmen, Haluk; Herzog, Michael H.


    Memory is an essential component of cognition and disorders of memory have significant individual and societal costs. The Atkinson–Shiffrin “modal model” forms the foundation of our understanding of human memory. It consists of three stores: Sensory Memory (SM), whose visual component is called iconic memory, Short-Term Memory (STM; also called working memory, WM), and Long-Term Memory (LTM). Since its inception, shortcomings of all three components of the modal model have been identified. While the theories of STM and LTM underwent significant modifications to address these shortcomings, models of the iconic memory remained largely unchanged: A high capacity but rapidly decaying store whose contents are encoded in retinotopic coordinates, i.e., according to how the stimulus is projected on the retina. The fundamental shortcoming of iconic memory models is that, because contents are encoded in retinotopic coordinates, the iconic memory cannot hold any useful information under normal viewing conditions when objects or the subject are in motion. Hence, half-century after its formulation, it remains an unresolved problem whether and how the first stage of the modal model serves any useful function and how subsequent stages of the modal model receive inputs from the environment. Here, we propose a new conceptualization of human visual sensory memory by introducing an additional component whose reference-frame consists of motion-grouping based coordinates rather than retinotopic coordinates. We review data supporting this new model and discuss how it offers solutions to the paradoxes of the traditional model of sensory memory. PMID:27375519

  7. Hyper Suprime-Cam: conceptual design to introduce spectroscopic mode (United States)

    Komiyama, Yutaka; Tanaka, Yoko; Miyazaki, Satoshi; Kawanomoto, Satoshi; Kamata, Yukiko; Nakaya, Hidehiko; Obuchi, Yoshiyuki; Uraguchi, Fumihiro; Utsumi, Yousuke


    Hyper Suprime-Cam (HSC) is the wide-field CCD camera which is attached to the prime focus of Subaru Telescope. It covers the field of view of 1.5 degree in diameter by 116 2k x 4k fully-depleted CCDs. In this paper, we present the conceptual design of optics and mechanics how to introduce spectroscopic mode to this simple imager HSC. The design is based on the idea that the optical elements such as collimeter, grisms and camera lenses are integrated as a 'filter' of HSC. The incident light is folded by pickup mirror at filter layer and introduced to the filter space. After passing the slit, the incident light is collimated by the collimeter lens and divided into three wavelength ranges by dichroic mirrors. The collimated beam in each wavelength range is fed to the grism and dispersed. The dispersed beam is converged by the camera lens and folded by 45 degree mirror to the direction parallel to the optical axis. The resultant spectra are imaged on the main CCDs on the focal plane. The space allowed for filters is 600 mm in diameter and 42 mm thick, which is very tight but we are able to design spectroscopic optics with some difficulties. The spectral resolution is designed to be more than 1000 and the wavelength coverage is targeted to be 370-1050 nm to realize medium-resolution spectroscopy for various type of objects. We show the optical design of collimeter, grism and camera lenses together with the mechanical layout of the spectroscopic optics.

  8. Desarrollo Conceptual: Perspectivas Actuales en la Adquisición Temprana de Conceptos Conceptual Development: Current Approaches to Children's Early Concept Acquisition

    Directory of Open Access Journals (Sweden)

    Andrea Sabina Taverna


    Full Text Available Se examinan cuatro propuestas teóricas actuales acerca de la formación y desarrollo temprano de conceptos: aproximaciones innatistas, enfoques asociacionistas, teorías del conocimiento nuclear y perspectivas socio-culturales. Las propuestas concuerdan en que los conceptos cumplen un rol importante en el desarrollo cognitivo, pero difieren marcadamente en el modo de explicar su adquisición y desarrollo temprano. Estas divergencias reeditan debates filosóficos clásicos acerca del lugar de la naturaleza, la experiencia, la razón y la cultura en el desarrollo del conocimiento. Se discute la necesidad de reconsiderar el desarrollo conceptual a la luz de modelos teóricos más inclusivos, si se pretende avanzar críticamente en una aproximación teórica general acerca de la formación y desarrollo de conceptos en la infancia.Four current theoretical proposals about early conceptual acquisition and development are examined: nativist perspectives, associationist views, core-knowledge theories, and socio-cultural approaches. The proposals agree that concepts play an important role in children's cognitive development, but they differ in their explanation as to how these are acquired and their early development. These differences date back to classical philosophical debates about the role of nature, experience, reason, and culture in the development of knowledge. The need to revisit conceptual development with a more inclusive theoretical approach is discussed, if critical advancement towards a general theoretical approach for understanding the formation and development of concepts in early childhood is to be achieved.

  9. Investigating and Promoting Trainee Science Teachers' Conceptual Change of the Nature of Science with Digital Dialogue Games `InterLoc' (United States)

    Mansour, Nasser; Wegerif, Rupert; Skinner, Nigel; Postlethwaite, Keith; Hetherington, Lindsay


    The purpose of this study is to explore how an online-structured dialogue environment supported (OSDE) collaborative learning about the nature of science among a group of trainee science teachers in the UK. The software used (InterLoc) is a linear text-based tool, designed to support structured argumentation with openers and `dialogue moves'. A design-based research approach was used to investigate multiple sessions using InterLoc with 65 trainee science teachers. Five participants who showed differential conceptual change in terms of their Nature of Science (NOS) views were purposively selected and closely followed throughout the study by using key event recall interviews. Initially, the majority of participants held naïve views of NOS. Substantial and favourable changes in these views were evident as a result of the OSDE. An examination of the development of the five participants' NOS views indicated that the effectiveness of the InterLoc discussions was mediated by cultural, cognitive, and experiential factors. The findings suggest that InterLoc can be effective in promoting reflection and conceptual change.

    Collins, L.; Collins, D


    As a comparatively recent development, the adventure-sports coach struggles for a clear and distinct identity. The generic term ‘instructor’ no longer characterizes the role and function of this subgroup of outdoor professionals. Indeed, although the fields of adventure/outdoor education and leadership are comparatively well researched, the arrival of this ‘new kid on the block’ appears to challenge both the adventure-sports old guard and traditional views of sports coaching.
