    Mortensen, Niels Henrik

    1999-01-01

    The majority of resources, like time and costs, consumed in industrial product development can be related to detailed design, i.e. the materialisation of machine parts (German Maschinenteile). Existing design theories based on a systems approach, e.g. Haberfellner [5] all have function, i.......e. transformation from input to output or ability to deliver purposeful effects as the core concept. The units in a product which posses functions are the organs (German: Funktionsträgern). Because individual parts do not posses functions, one could argue that the design theories based on a systems approach...... to be identification of a purposeful behaviour concept, i.e. function for a machine part. The contribution is based on the theory of technical systems, Hubka and the domain theory, Andreasen....

    2017-03-01

    This paper proposes a methodology to derive architectures and operational concepts for future earth-to-orbit and sub-orbital transportation systems. In particular, at first, it describes the activity flow, methods, and tools leading to the generation of a wide range of alternative solutions to meet the established goal. Subsequently, the methodology allows selecting a small number of feasible options among which the optimal solution can be found. For the sake of clarity, the first part of the paper describes the methodology from a theoretical point of view, while the second part proposes the selection of mission concepts and of a proper transportation system aimed at sub-orbital parabolic flights. Starting from a detailed analysis of the stakeholders and their needs, the major objectives of the mission have been derived. Then, following a system engineering approach, functional analysis tools as well as concept of operations techniques allowed generating a very high number of possible ways to accomplish the envisaged goals. After a preliminary pruning activity, aimed at defining the feasibility of these concepts, more detailed analyses have been carried out. Going on through the procedure, the designer should move from qualitative to quantitative evaluations, and for this reason, to support the trade-off analysis, an ad-hoc built-in mission simulation software has been exploited. This support tool aims at estimating major mission drivers (mass, heat loads, manoeuverability, earth visibility, and volumetric efficiency) as well as proving the feasibility of the concepts. Other crucial and multi-domain mission drivers, such as complexity, innovation level, and safety have been evaluated through the other appropriate analyses. Eventually, one single mission concept has been selected and detailed in terms of layout, systems, and sub-systems, highlighting also logistic, safety, and maintainability aspects.

    Full Text Available Lean production has been applied by organizations around the world as part of strategy to reduce waste in their value stream intending to improve performance. Despite the use of lean production concepts and tools have continually been introduced in different companies, the literature shows the most of application is identified in large companies than in Small-and  Medium-sized Enterprises (SMEs. The reason can be the lack of financial and human resources available to the lean initiatives in these enterprises. However, a wide range of concepts and techniques of lean production can be applied without considerable financial investments. This paper aims to study the opportunities and difficulties of lean production applicability in SMEs. Case research was developed in three SMEs of industrial cluster of Jaú/SP and the results suggest that these companies face similar difficulties. Nevertheless, the study confirms that there are several opportunities to implement lean production concepts and techniques which can lead to improve performance in these companies.

  7. Petri nets - part 1: concepts and application areas

    International Nuclear Information System (INIS)

    Sivertsen, Terje

    2004-03-01

    There exist a number of models, languages, methods, and tools that support the specification and analysis of system requirements. One important class comprises graphical methods based on the concept of Petri nets. Due to the wide variety of applications, these methods are relevant also in research and applications outside the digital systems safety domain. The present report constitutes the first of three parts of a unified exposition of graphical methods based on the concept of Petri nets. The report provides an introduction to basic concepts of Petri nets and an overview of a wide variety of application areas. The second part of the trilogy will present a number of techniques and tools. The third part will focus on analysis. Petri nets have been proposed for a wide variety of applications, and new areas are considered as new challenges emerge from scientific, technological, and social developments. The wide variety of application areas reflects a broad interest in Petri nets, coming from diverse directions. Empirically, as well as theoretically, there are good reasons to claim that Petri nets are applicable for many different kinds of problems. What is common to the different applications and problems addressed is the need for a formalism that allows adequate representation of important system characteristics like concurrency, asyncronicity, distribution, parallelism, and non-determinism. Several of the references in the report discuss NPP-related applications, or applications with great potentials for technology transfer from other areas to the nuclear domain. (Author)

    2015-05-01

    Part-time work concepts are requested for different reasons from an increasing number of employees. Despite this fact there are no systematic part-time work concepts published in the German literature, especially for physicians working in hospitals. This article describes background and circumstances of a part-time work concept which was established two years ago in a department of anaesthesiology at a university hospital in Germany. This concept considers needs of young families as well as older employees. We are convinced that a transparent part-time work concept is a good argument for job-seeking physicians when deciding for an employer. The benefit for the already employed colleagues has at least the same value. © Georg Thieme Verlag Stuttgart · New York.

  12. Investigation of novel propulsion systems – the exoskeletal engine concept. Part I

    Directory of Open Access Journals (Sweden)

    Iulian JUHASZ

    2010-09-01

    Full Text Available The exoskeletal engine represents a relatively new concept in the world of propulsion systems. It is a drum-rotor engine concept in which conventionally heavy shafts and discs are eliminated and replaced by rotating casings that support the blades in span wise compression. Thus the rotating blades are in compression rather than in tension. The resulting open channel at the engine centreline has an immense potential for the jet noise reduction and can also accommodate an inner combined-cycle thruster such as a ramjet. This is the first part of an article constituted out of two parts.

  13. Concepts of occlusion in prosthodontics: A literature review, part I

    Directory of Open Access Journals (Sweden)

    V Rangarajan

    2015-01-01

    Full Text Available Occlusion and its relationship to the function of the stomatognathic system have been widely studied in dentistry since many decades. This series of articles describe about occlusion in the complete denture, fixed partial denture, and implants. Part I and II of this articles series describe concepts and philosophies of occlusion in complete denture. So far, available research has not concluded a superior tooth form or occlusal scheme to satisfy the requirements of completely edentulous patients with respect to comfort, mastication, phonetics, and esthetics. Since then, several balanced and nonbalanced articulation concepts were proposed in the literature. A balanced articulation appears to be most appropriate because of tooth contacts observed during nonfunctional activities of patients. This article discusses about evolution of different concepts of occlusion and occlusal schemes in complete denture occlusion.

    Farassat, Fereidoun; Myers, Michael K.

    2011-01-01

    This paper is the first part of a three part tutorial on multidimensional generalized functions (GFs) and their applications in aeroacoustics and fluid mechanics. The subject is highly fascinating and essential in many areas of science and, in particular, wave propagation problems. In this tutorial, we strive to present rigorously and clearly the basic concepts and the tools that are needed to use GFs in applications effectively and with ease. We give many examples to help the readers in understanding the mathematical ideas presented here. The first part of the tutorial is on the basic concepts of GFs. Here we define GFs, their properties and some common operations on them. We define the important concept of generalized differentiation and then give some interesting elementary and advanced examples on Green's functions and wave propagation problems. Here, the analytic power of GFs in applications is demonstrated with ease and elegance. Part 2 of this tutorial is on the diverse applications of generalized derivatives (GDs). Part 3 is on generalized Fourier transformations and some more advanced topics. One goal of writing this tutorial is to convince readers that, because of their powerful operational properties, GFs are absolutely essential and useful in engineering and physics, particularly in aeroacoustics and fluid mechanics.

    Tanaka, Daisuke

    2010-03-01

    Fragment-Based Drug Discovery (FBDD) has been recognized as a newly emerging lead discovery methodology that involves biophysical fragment screening and chemistry-driven fragment-to-lead stages. Although fragments, defined as structurally simple and small compounds (typically FBDD primarily turns our attention to weakly but specifically binding fragments (hit fragments) as the starting point of medicinal chemistry. Hit fragments are then promoted to more potent lead compounds through linking or merging with another hit fragment and/or attaching functional groups. Another positive aspect of FBDD is ligand efficiency. Ligand efficiency is a useful guide in screening hit selection and hit-to-lead phases to achieve lead-likeness. Owing to these features, a number of successful applications of FBDD to "undruggable targets" (where HTS and other lead identification methods failed to identify useful lead compounds) have been reported. As a result, FBDD is now expected to complement more conventional methodologies. This review, as an introduction of the following articles, will summarize the fundamental concepts of FBDD and will discuss its advantages over other conventional drug discovery approaches.

    The concept of integrated services delivery, although dating from the 1990s, has only recently appeared in the French public health policy. To clarify the concept and its adaptation to the reality of the French systems of healthcare and social services, the French Society of Geriatrics and Gerontology established an interdisciplinary working group. This article reports the group's findings according to three axes: the definition of integration, the objectives of this organizational approach and the means needed to achieve them. Analysis of the literature indicated that integration is a process that aims to overcome the fragmentation of services for vulnerable people. This process requires a multilevel approach, particularly concerning how to modify public policies and financing systems. Notably, all relevant levels need to develop shared processes, tools, resources, finance, interventions and feed-back on the latter. Indeed, this sharing is the ultimate proof of evolution towards integration. In this first part of the position paper, its authors analyzed integrated care definitions used in international literature in view of designing the most important components of integrated care. The examination of this concept must be articulated with the idea of "coordination" which has been the cornerstone of the majority of public policies applied to the field of geriatrics and gerontology since the 1960s in France. The components of integrated care highlight that it is an ambitious process leading to real systemic modification. The authors also have proposed to open up a dialogue between citizens' aspirations and integrated care objectives with the aim to verify that the latter respond to the needs as expressed by the targeted group.

    2012-01-01

    Full Text Available Enterprise competitiveness in the era of knowledge economy is most directly connected to human and other intellectual resources. Managers and other employees become vital resource in the 21st century, and their knowledge is the key of creating and delivering superior value to the customers. Nowadays, they are one of the most important segments of assets without which enterprise cannot exist. Crucial question for management is how to enlarge other knowledge resources based on human resources knowledge, that is, their economically- relevant form - intellectual capital. Initial hypothesis of this paper is that, internal marketing, which has enterprise's employees in the focus, can create adequate basis for specializing and enlarging knowledge resources - intellectual resources or intellectual capital as a key factor of competitiveness in the era of knowledge economy. Knowledge management is observed as a segment of intellectual capital management process within an enterprise, with aim to direct the efficient usage of all kinds of knowledge (individual, group-team, organizational in order to create new business opportunities and successful commercialisations of products/services. The aim of this paper is to indicate that complementary application of the concept of internal marketing and the concept of knowledge management may result in synergetic effect of enlargement and specialisation of the knowledge resources - intellectual capital. In the paper we use methods of scientific observation, testing and connecting, as well as methods of analysis and synthesis. The purpose of obtained results application and conclusions from this research is to show to the enterprise management the importance of simultaneous effective application of internal marketing concept and knowledge transfer through processes and practices of knowledge management.

    those that did not, we were able to develop an ex post theory of what is needed for an organization or community to successfully pursue the Triple Aim. Drawing on our 7 years of experience, we describe the 3 major principles that guided the organizations and communities working on the Triple Aim: creating the right foundation for population management, managing services at scale for the population, and establishing a learning system to drive and sustain the work over time. The concept of the Triple Aim is now widely used, because of IHI's work with many organizations and also because of the adoption of the Triple Aim as part of the national strategy for US health care, developed during the implementation of the Patient Protection and Affordable Care Act of 2010. Even those organizations working on the Triple Aim before IHI coined the term found our concept to be useful because it helped them think about all 3 dimensions at once and organize their work around them. © 2015 Milbank Memorial Fund.

    2001-01-01

    A main impediment to optimization of the plant maintenance is the fact that we can not predict when and how troubles are introduced in a plant. Having regard to the point, the authors propose a 'virtual system' concept for prevention and prediction of accidents in plants. The virtual system is a system constructed in computers and it evaluates responses to various loads of the object system. The authors introduce the resistance to loads and the testing availability as key parameters characterizing object sub-systems and place their evaluation as the first step of construction of the virtual system.

  8. A joint spare part and maintenance inspection optimisation model using the Delay-Time concept

    International Nuclear Information System (INIS)

    Wang Wenbin

    2011-01-01

    Spare parts and maintenance are closely related logistics activities where maintenance generates the need for spare parts. When preventive maintenance is present, it may need more spare parts at one time because of the planned preventive maintenance activities. This paper considers the joint optimisation of three decision variables, e.g., the ordering quantity, ordering interval and inspection interval. The model is constructed using the well-known Delay-Time concept where the failure process is divided into a two-stage process. The objective function is the long run expected cost per unit time in terms of the three decision variables to be optimised. Here we use a block-based inspection policy where all components are inspected at the same time regardless of the ages of the components. This creates a situation that the time to failure since the immediate previous inspection is random and has to be modelled by a distribution. This time is called the forward time and a limiting but closed form of such distribution is obtained. We develop an algorithm for the optimal solution of the decision process using a combination of analytical and enumeration approaches. The model is demonstrated by a numerical example. - Highlights: → Joint optimisation of maintenance and spare part inventory. → The use of the Delay-Time concept. → Block-based inspection. → Fixed order interval but variable order quantity.

    2014-01-01

    Aim The aim of this study was to describe, explore and explain the concept of sustainability in nursing. Background Although researchers in nursing and medicine have emphasised the issue of sustainability and health, the concept of sustainability in nursing is undefined and poorly researched. A need exists for theoretical and empirical studies of sustainability in nursing. Design Concept analysis as developed by Walker and Avant. Method Data were derived from dictionaries, international healthcare organisations and literature searches in the CINAHL and MEDLINE databases. Inclusive years for the search ranged from 1990 to 2012. A total of fourteen articles were found that referred to sustainability in nursing. Results Sustainability in nursing involves six defining attributes: ecology, environment, future, globalism, holism and maintenance. Antecedents of sustainability require climate change, environmental impact and awareness, confidence in the future, responsibility and a willingness to change. Consequences of sustainability in nursing include education in the areas of ecology, environment and sustainable development as well as sustainability as a part of nursing academic programs and in the description of the academic subject of nursing. Sustainability should also be part of national and international healthcare organisations. The concept was clarified herein by giving it a definition. Conclusion Sustainability in nursing was explored and found to contribute to sustainable development, with the ultimate goal of maintaining an environment that does not harm current and future generations′ opportunities for good health. This concept analysis provides recommendations for the healthcare sector to incorporate sustainability and provides recommendations for future research. PMID:24602178

  10. New HTGR plant concept with inherently safe features aimed at small energy users needs

    International Nuclear Information System (INIS)

    McDonald, C.F.; Silady, F.S.; Shenoy, A.S.

    1982-01-01

    A small high-temperature gas-cooled reactor (HTGR) concept is proposed which could provide the energy needs for certain sectors of industrialized nations and the developing countries. The key to the economic success for small reactors, which have potential benefits for special markets, lies in altering the traditional scaling laws. Toward this goal, a small HTGR concept embodying passive decay heat removal features is currently being evaluated. This paper emphasizes the safety-related aspects of a small HTGR. The proposed small reactor concept is new and still in the design development stage, and a significant effort must be expended to establish a design which is technically and economically feasible and will meet the increasingly demanding safety and licensing goals for reactors of the future

    False concessive failure of students is students construction failure in achieving goals, where the process is false, the results obtained is true. This failure occurs because the schemes are not connected to each other, so it cannot form a new scheme. This research is a qualitative research that aim to describe the characteristics of students' false concessive failure on fractional concepts. This fractional concept is a fraction of the same part of the whole. To be able to solve the concept of this fraction, students must possess the concept of partition, the concept of addition and the concept of multiplication of the fraction.

    The aim of this article is apply of Formal Concept Analysis on concept of world. Formal concept analysis (FCA) as a methodology of data analysis, information management and knowledge representation has potential to be applied to a verity of linguistic problems. FCA is mathematical theory for concepts and concept hierarchies that reflects an understanding of concept. Formal concept analysis explicitly formalizes extension and intension of a concept, their mutual relationships. A distinguishing feature of FCA is an inherent integration of three components of conceptual processing of data and knowledge, namely, the discovery and reasoning with concepts in data, discovery and reasoning with dependencies in data, and visualization of data, concepts, and dependencies with folding/unfolding capabilities.

  13. Heritage building as a Concept and as a part of Technology Education Conceptions of, structuredness of conceptions of, and conceptual change in students in teacher training during a study module on heritage building

    Directory of Open Access Journals (Sweden)

    Jani Kaasinen

    2017-12-01

    Full Text Available As a concept, heritage building is young and previously undefined in Finnish scientific literature. Earlier studies about the very notions of heritage building are also nonexistent in Finland. The purpose of the present study was to investigate the conceptions of students in teacher training about heritage building before and after a study module on heritage building, which constitutes a part of their subject studies in didactics of crafts. The lack of previous studies about conceptions of heritage building in Finland led to the selection of these conceptions as a research target. The study uses two different approaches for achieving its purpose. In order to find answers to the research problem, the students' common conceptions about heritage building were examined first. Secondly, it was considered how structured these conceptions were. Therefore, the research process included a conceptual review of heritage building to provide a baseline for comparing the student's conceptions and their structuredness.The research results indicate that even though students in didactics of handicrafts have conceptions about heritage building that are parallel with the definition formulated for the purposes of the study, they are superficial on average. The review of structuredness of conceptions supported the results achieved in the phenomenographical analysis of conceptions. It was observed that completing the study module had an impact on the structuredness of conceptions. Furthermore, the students' personal background was found to have some implications on how structured their conceptions of heritage building were, which was evidenced by notable differences in structuredness of conceptions on an individual level. This article is based on the writer’s doctoral dissertation.Keywords: Heritage building, conceptions, conceptual change, level of structuredness, phenomenography, technology education

  14. The "spare parts person"? Conceptions of the human body and their implications for public attitudes towards organ donation and organ sale

    Schweda, Mark; Schicktanz, Silke

    2009-01-01

    Background The increasing debate on financial incentives for organ donation raises concerns about a "commodification of the human body". Philosophical-ethical stances on this development depend on assumptions concerning the body and how people think about it. In our qualitative empirical study we analyze public attitudes towards organ donation in their specific relation to conceptions of the human body in four European countries (Cyprus, Germany, the Netherlands and Sweden). This approach aims at a more context-sensitive picture of what "commodification of the body" can mean in concrete clinical decisions concerning organ donation. Results We find that moral intuitions concerning organ donation are rooted in various conceptions of the human body and its relation to the self: a) the body as a mechanical object owned by the self, b) the body as a part of a higher order embodying the self, and c) the body as a hierarchy of organs constitutive of the self. Conclusion The language of commodification is much too simple to capture what is at stake in everyday life intuitions about organ donation and organ sale. We discuss how the plurality of underlying body-self conceptions can be taken into account in the ethical debate, pointing out consequences for an anthropologically informed approach and for a liberal perspective.

    Reflexology is basically a study of how one part of the human body relates to another part of the body. Reflexology practitioners rely on the reflexes map of the feet and hands to all the internal organs and other human body parts. They believe that by applying the appropriate pressure and massage certain spots on the feet and hands, all other body parts could be energized and rejuvenated. This review aimed to revisit the concept of reflexology and examine its effectiveness, practices, and th...

  16. On the concepts of inwardness and subjectivity in Shakespeare's work

    2016-12-01

    Full Text Available This essay aims at discussing the concepts of subjectivity and inwardness in Early Renaissance. The issue discussed in this research is to take into account that both concepts are interchangeable, since they represent distinct notions of the similar phenomenon: the inner space of sensations, emotions, feelings, and identity. The concept of identity was associated to the perception of an inner space of the subject in the 16th and 17th centuries. It was always compared and defined parting from the notion of physical and gestural appearances, whose discursive forms were always based on the perceptive movement from the outward to the inward space of the subject. On the other hand, subjectivity is a modern concept which emerges from the 19th onward whose discursive forms part form the inner space of the subject, without taking into consideration the physical and gestural appearances. This research is bibliographic and uses some examples from the dramaturg William Shakespeare. As it was observed, the concepts of subjectivity and inwardness are not synonyms, once they part from distinct philosophic and psychologic perspectives, besides that they are still perceive until our times.

    2016-05-01

    Full Text Available Aim: The aim of this literature review was to search for qualitative studies focusing on the concept of caring in nursing, to analyse them and to synthesize knowledge that concerns the definition of the concept of caring in nursing from the point of view of nurses and patients. Design: Review. Methods: Qualitative studies were searched for systematically in the electronic databases Academic Search Complete (EBSCO, CINAHL, Medline, Science Direct, and the Wiley Library Online, according to set criteria and defined key words for the period 1970-2015. Seven selected articles were analysed after selection of documents with the aid of a sorting chart. Results: Nurses understand caring in nursing as a relationship with patients which is characterised on the nurses' part by an individual and empathetic approach, attentiveness, experience and sensitivity. Through caring, active communication takes place, providing information which reduces anxiety and leads to the breaking down of barriers. This relationship helps protect patients' autonomy, dignity and comfort. It requires experience on the part of nurses, and it is influenced by the environment. The nurses' personal qualities (what professional knowledge, attitudes and skills they have and their availability, reliability, and emotional and physical support are important to patients. Conclusion: The concept of caring is a content specific interpersonal process which is characterized by the professional knowledge, skills, personal maturity, and interpersonal sensitivity of nurses, which result in the protection, emotional support, and the meeting of bio-psycho-social needs of patients. The results of the overview study could contribute to an explanation and understanding of the nature of caring as a fundamental feature of the discipline of nursing.

    This classic text, aimed at senior undergraduates and beginning graduate students in physics and astronomy, presents a wide range of astrophysical concepts in sufficient depth to give the reader a quantitative understanding of the subject. Emphasizing physical concepts, the book outlines cosmic events but does not portray them in detail: it provides a series of astrophysical sketches. For this fourth edition, nearly every part of the text has been reconsidered and rewritten, new sections have been added to cover recent developments, and others have been extensively revised and brought up to date. The book begins with an outline of the scope of modern astrophysics and enumerates some of the outstanding problems faced in the field today. The basic physics needed to tackle these questions are developed in the next few chapters using specific astronomical processes as examples. The second half of the book enlarges on these topics and shows how we can obtain quantitative insight into the structure and evolution of...

    This paper presents an overview of a new concept for DCSs developed within the KBRTCS (Knowledge-Based Real-Time Control Systems) project performed between 1988 and 1991 as a part of the Swedish IT4 programme. The partners of the project have been the Department of Automatic Control at Lund University, Asea Brown Boveri, and during parts of the project, SattControl, and TeleLogic. The aim of the project has been to develop a concept for future generations of DCSs based on a plant database containing a description of the plant together with the control system. The database is object-based and supports multiple views of an objects. A demonstrator is presented where a DCS system of this type is emulated. The demonstrator contains a number of control, monitoring, and diagnosis applications that execute in real time against a simulations of Steritherm sterilization process. (25 refs.)

  1. A systematic concept of assuring structural integrity of components and parts for applying to highly ductile materials through brittle material

    International Nuclear Information System (INIS)

    Suzuki, Kazuhiko

    2007-09-01

    Concepts of assuring structural integrity of plant components have been developed under limited conditions of either highly ductile or brittle materials. There are some cases where operation in more and more severe conditions causes a significant reduction in ductility for materials with a high ductility before service. Use of high strength steels with relatively reduced ductility is increasing as industry applications. Current concepts of structural integrity assurance under the limited conditions of material properties or on the requirement of no significant changes in material properties even after long service will fail to incorporate expected technological innovations. A systematic concept of assuring the structural integrity should be developed for applying to highly ductile materials through brittle materials. Objectives of the on-going research are to propose a detail of the systematic concept by considering how we can develop the concept without restricting materials and for systematic considerations on a broad range of material properties from highly ductile materials through brittle materials. First, background of concepts of existing structural codes for components of highly ductile materials or for structural parts of brittle materials are discussed. Next, issues of existing code for parts of brittle materials are identified, and then resolutions to the issues are proposed. Based on the above-mentioned discussions and proposals, a systematic concept is proposed for application to components with reduced ductility materials and for applying to components of materials with significantly changing material properties due to long service.

    2017-01-01

    The advancements in nanotechnology especially in medicine and in developing new materials offer interesting possibilities for our society. It is not only scientists and engineers who need a better understanding of these new technologies but it is also important to prepare the young people and the general public on impact of nanotechnology on their life. Knowledge from this field likewise provides the opportunities to engage and motivate high school students for the study of science. Although, the concepts of nanoscience and nanotechnology are not a part of Czech high school physics curriculum they can be successfully integrated into regular curriculum in appropriate places. Because it is an interdisciplinary field, it also provides an opportunity for the interdisciplinary connections of physics, chemistry and biology. Many concepts for understanding the nanoworld can be shown by the simple activities and experiments and it is not a problem to demonstrate these experiments in each classroom. This paper presents the proposal for integration of the concepts of nanoscience and nanotechnologies into the high school physics curriculum, and the involvement of some of these concepts into the instructional program for middle and high school students which was realized in interactive science museum Fort Science in Olomouc. As a part of the program there was a quantitative questionnaire and its goal was to determine the effectiveness of the program and how students are satisfied with it.

    The aim of this study was to describe the content knowledge especially the concept of fraction of prospective elementary school teacher. The purpose of this study is to describe the content knowledge, especially the concept of fraction of prospective elementary school teacher. The subject of the study was one of prospective elementary school teacher of Pattimura University. This research is qualitative research. Data were collected through the provision of tests to explore the knowledge content of primary school teacher candidates about fractional concepts. Then continued with qualitative data analysis. The results of this study are as follows: that the prospective primary school teacher defines fractions as part of the whole if an object is divided into equal parts, so that the part that has been divided is part of the whole. Furthermore, the prospective elementary school teacher understood the fractions as division shown in two ways, namely the prospective elementary school teacher understood the fraction as a division operation, the primary school teacher candidate interpreted the fraction as a division when an object is divided be part of the same. Meanwhile, the fraction as a ratio is interpreted as the relationship between a pair of numbers. Then, the denominations are interpreted as a ratio between the numerator and the denominator of the same value. The prospective elementary school teacher also understands fractions of value when simplifying fractions. Primary school teacher candidates understand the concept of fractional operations.

    The concept of integrated services delivery, although dating from the 1990s, has only recently appeared in French public health policy. To clarify the concept and its adaptation to the reality of the French systems of healthcare and social services, the French Society of Geriatrics and Gerontology established an interdisciplinary working group. This article reports that group's findings according to three axes: the definition of integration, the objectives of this organizational approach and the means needed to achieve them. Analysis of the literature indicated that integration is a process that aims to overcome the fragmentation of services for vulnerable people. This process requires a multilevel approach, particularly concerning how to modify public policies and financing systems. Notably, all relevant levels need to develop shared processes, tools, resources, finance, interventions and returns on the latter. Indeed, this sharing is the ultimate proof of evolution towards integration. In the second part of the position paper, its authors have developed arguments that could lead professionals and non-professional caregivers to adopt integrated care as an answer to their aspirations. Policy-maker perspectives and politicians are also analyzed. Bearing in mind that integrated care necessarily will always involve a human component which may find expression during individual case-management; relations between integration and case managements are clarified. Finally, lessons learned from national and international experiments are examined. Results suggest that integrated care must to be accompanied by a local pilot. Results of recent experiments have shown that it is possible to initiate a dynamic towards integrated care in France and hence join the international movement towards adapting our healthcare systems to new challenges.

    Full Text Available We present a reflection regarding operations with fractional numbers focusing on the part-all conception through some activities that can contribute to teaching practices at the elementary school level. A brief characterization of the all-part conception is provided along with descriptions of activities involving the four basic operations based on the use of flat figures, although other conceptions may emerge during the solution. We limit our considerations to this conception because it is the most frequent, in textbooks as well as teacher practice, although it is not used to justify operational rules of fractional numbers. Key-words: Fractions. Fractional Numbers. Operations.Neste artigo, apresentamos uma reflexão a respeito das operações com números fracionários focalizando a concepção parte-todo por meio de algumas atividades que possam contribuir para a prática docente na escola básica. O estudo explicita uma breve caracterização da concepção parte-todo e atividades envolvendo as quatro operações fundamentais tratadas em figuras planas, embora outras concepções possam ser mobilizadas durante a solução. Restringimos nossas considerações a essa concepção visto ser a mais freqüente, tanto em livros didáticos, quanto na prática do professor, embora não seja utilizada para justificar as regras operatórias dos números fracionários.

    To inform reproductive and other health care providers about pre-conception evaluation, including considerations for reproductive planning, lifestyle modification, immunization status and attitudes, and psychosocial issues. This counselling information can be used for patient education and planning and possible pre-conception and/or prenatal testing. This information may allow for improved risk assessment when pre-conception counselling for individual patients and their families is used. CONSIDERATIONS FOR PRE-CONCEPTION CARE (PART 2) REGARDING PRE-CONCEPTION REPRODUCTIVE PLANNING, LIFESTYLE, IMMUNIZATIONS, AND PSYCHOSOCIAL ISSUES: CONSIDERATION FOR CARE STATEMENTS: For this review article, the Consideration for Care Statements use the Grading of Recommendations, Assessment, Development and Evaluations strength and quality principles because they are comparable for the clinician and the patient/public user. For example, "Strong" for clinicians is defined as "the recommendation would apply to most individuals. Formal discussion aids are not likely to be needed to help individuals make decisions consistent with their values and preferences." For patients/the public, "Strong" is defined as, "we believe most people in this situation would want the recommended course of actions and only a small number would not." Quality of evidence (High, Moderate, Low) is based on the confidence that the true effect lies close to that of the estimate of the effect. In addition, the Canadian Task Force on Preventive Health Care key to evidence statements and grading of recommendations are included. PubMed, Medline, and the Cochrane Database were searched until May 2017, using appropriate key words (i.e., preconception, reproductive planning, lifestyle modification, immunization risks and benefits, psychosocial pregnancy factors/issues). Grey (unpublished) literature was identified through searching websites of health technology assessment and health technology assessment

  10. Development of numerical concepts

    2013-06-01

    Full Text Available The development of numerical concepts is described from infancy to preschool age. Infants a few days old exhibit an early sensitivity for numerosities. In the course of development, nonverbal mental models allow for the exact representation of small quantities as well as changes in these quantities. Subitising, as the accurate recognition of small numerosities (without counting, plays an important role. It can be assumed that numerical concepts and procedures start with insights about small numerosities. Protoquantitative schemata comprise fundamental knowledge about quantities. One-to-one-correspondence connects elements and numbers, and, for this reason, both quantitative and numerical knowledge. If children understand that they can determine the numerosity of a collection of elements by enumerating the elements, they have acquired the concept of cardinality. Protoquantitative knowledge becomes quantitative if it can be applied to numerosities and sequential numbers. The concepts of cardinality and part-part-whole are key to numerical development. Developmentally appropriate learning and teaching should focus on cardinality and part-part-whole concepts.

    The 'technological conception' examines how a project can be concretized or how it is possible to 'conceive', i.e. to produce operative ideas that can be directly use. The first part of this book, called 'concepts and methods', analyzes the logics of conceiving and its philosophy in the construction of its objects and in the management of its programs or projects. The second part is devoted to some exemplary technologies: roads, tunnels, bridges, dams, nuclear power plants, aerospace constructions, and analyzes different concrete logics of technological conception. Finally, the author shows how todays conception faces the risks and complexity increase of systems and considers the possibility of an entirely automated manufacturing shop in the future. (J.S.)

    2012-01-01

    Full Text Available This article presents results of an investigation developed as part of a Master's Thesis (Bortolai, 2010 that aimed to report on the resignification of the concept of transformation by first-year students of a governmental high school located in the city of São Paulo (São Paulo State, Brazil. The activities selected for analyzing the reframing of this concept were, at first, performed individually by the students. Afterwards, a discussion was held among the students, together with the school teacher, to prepare a collective synthesis, pointing to more specific features of the systems before and after the transformation process. Then, two other activities were proposed that aimed to probe the redefinition, by the students, of the concept under study. This provided the data for verifying the stages of thought processes for concept formation in adolescents, along the lines of Vygotsky’s proposals (2005. It was observed that some of the students require further discussions to change their ideas in order to achieve the stage of conceptual thought, through the mobilization of their superior mental functions.

    The author maintains that the de minimis concept does not have the same legal connotations as a license exemption or a general license, nor is it the same concept as ALARA (as low as reasonably achievable), and to equate this concept with any of the three is erroneous. He discusses the concept with regard to the revision of 10 CFR Part 20 regulations and concludes that incorporating de minimis into Part 20 is preferable to including it in other parts, that legal precedents for doing so exist, and that coordinating with the Environmental Protection Agency is expected in formulating the concept for inclusion in Part 20

  15. Ontological Analysis of the Project Risk Management Concept ‘Risk’

    Directory of Open Access Journals (Sweden)

    Uzulāns Juris

    2018-02-01

    Full Text Available The aim of the current research series is to examine the definitions of the concept ‘risk’ and analyze the concepts used in the definitions of ‘risk’ in the sources of these definitions in order to perform the ontological analysis of the concept of ‘risk’. Ontological and epistemological analysis of the concepts in the definition of the concept ‘risk’ was used to answer the question what ‘risk’ means in project management. This investigation represents a part of the research series where the ontological, epistemological and methodological analysis of project risk is performed with the aim to improve risk registers and risk management as a whole. In the previous studies the author analyzed the concept of ‘event’ that defines the content of the concept ‘risk’. The use of ‘event’ was analyzed in different sources to find out how the concept should be used. The ontological, epistemological and methodological analysis of the definitions of the concept ‘risk’ is the theoretical foundation for risk register creation because it is possible to create complete and understandable register for the participants of the project risk management process. The author believes that the conducted research helps establish confidence that ontological analysis is the method that together with the epistemological and methodological analysis provides opportunity to perform analysis of risk management sources aimed at improving risk management. The results of the study cannot be considered sufficient for deriving valid conclusions about project risk management and developing recommendations for improving risk management with regard to the content of the risk register. For valid conclusions and recommendations, a deeper research is needed which, first of all, would analyze a larger number of sources.

    2002-12-01

    Current understanding of how muscles coordinate walking in humans is derived from analyses of body motion, ground reaction force and EMG measurements. This is Part I of a two-part review that emphasizes how muscle-driven dynamics-based simulations assist in the understanding of individual muscle function in walking, especially the causal relationships between muscle force generation and walking kinematics and kinetics. Part I reviews the strengths and limitations of Newton-Euler inverse dynamics and dynamical simulations, including the ability of each to find the contributions of individual muscles to the acceleration/deceleration of the body segments. We caution against using the concept of biarticular muscles transferring power from one joint to another to infer muscle coordination principles because energy flow among segments, even the adjacent segments associated with the joints, cannot be inferred from computation of joint powers and segmental angular velocities alone. Rather, we encourage the use of dynamical simulations to perform muscle-induced segmental acceleration and power analyses. Such analyses have shown that the exchange of segmental energy caused by the forces or accelerations induced by a muscle can be fundamentally invariant to whether the muscle is shortening, lengthening, or neither. How simulation analyses lead to understanding the coordination of seated pedaling, rather than walking, is discussed in this first part because the dynamics of pedaling are much simpler, allowing important concepts to be revealed. We elucidate how energy produced by muscles is delivered to the crank through the synergistic action of other non-energy producing muscles; specifically, that a major function performed by a muscle arises from the instantaneous segmental accelerations and redistribution of segmental energy throughout the body caused by its force generation. Part II reviews how dynamical simulations provide insight into muscle coordination of walking.

    2014-06-01

    The aim of this study was to describe, explore and explain the concept of sustainability in nursing. Although researchers in nursing and medicine have emphasised the issue of sustainability and health, the concept of sustainability in nursing is undefined and poorly researched. A need exists for theoretical and empirical studies of sustainability in nursing. Concept analysis as developed by Walker and Avant. Data were derived from dictionaries, international healthcare organisations and literature searches in the CINAHL and MEDLINE databases. Inclusive years for the search ranged from 1990 to 2012. A total of fourteen articles were found that referred to sustainability in nursing. Sustainability in nursing involves six defining attributes: ecology, environment, future, globalism, holism and maintenance. Antecedents of sustainability require climate change, environmental impact and awareness, confidence in the future, responsibility and a willingness to change. Consequences of sustainability in nursing include education in the areas of ecology, environment and sustainable development as well as sustainability as a part of nursing academic programs and in the description of the academic subject of nursing. Sustainability should also be part of national and international healthcare organisations. The concept was clarified herein by giving it a definition. Sustainability in nursing was explored and found to contribute to sustainable development, with the ultimate goal of maintaining an environment that does not harm current and future generations' opportunities for good health. This concept analysis provides recommendations for the healthcare sector to incorporate sustainability and provides recommendations for future research. © 2014 The Authors.

  20. Application of artificial intelligence (AI) concepts to the development of space flight parts approval model

    Science.gov (United States)

    Krishnan, Govindarajapuram Subramaniam

    1997-12-01

    The National Aeronautics & Space Administration (NASA), the European Space Agency (ESA), and the Canadian Space Agency (CSA) missions involve the performance of scientific experiments in Space. Instruments used in such experiments are fabricated using electronic parts such as microcircuits, inductors, capacitors, diodes, transistors, etc. For instruments to perform reliably the selection of commercial parts must be monitored and strictly controlled. The process used to achieve this goal is by a manual review and approval of every part used to build the instrument. The present system to select and approve parts for space applications is manual, inefficient, inconsistent, slow and tedious, and very costly. In this dissertation a computer based decision support model is developed for implementing this process using artificial intelligence concepts based on the current information (expert sources). Such a model would result in a greater consistency, accuracy, and timeliness of evaluation. This study presents the methodology of development and features of the model, and the analysis of the data pertaining to the performance of the model in the field. The model was evaluated for three different part types by experts from three different space agencies. The results show that the model was more consistent than the manual evaluation for all part types considered. The study concludes with the cost and benefits analysis of implementing the models and shows that implementation of the model will result in significant cost savings. Other implementation details are highlighted.

    The concept of professional commitment is being widely studied at present. However, although it is considered an indicator for the most human part of nursing care, there is no clear definition for it, and different descriptors are being used indiscriminately to reference it. The aim of this study is to clarify the concept of professional commitment in nursing through the Rodgers' evolutionary concept analysis process. Systematic search using English and Spanish descriptors and concept analysis. Studies published between 2009 and June 2015, front-to-back analysis of the Nursing Ethics journal and manual check of articles cited in studies related to the Nijmegen Professionalism Scale. The procedure of concept analysis developed by Rodgers was used. Ethical considerations: Although the topic was not labeled as sensitive and subject to ethical approval, its realization was approved by the Ethical Committee of Clinical Research of Aragon (CEICA) approved the study on 18 March 2015 and also careful procedures have been followed according to ethics expressed in the Declaration of Helsinki. A total of 17 published studies. A clear definition of the concept was made, and surrogate terms, concept dimension, differential factors related to the concept, sociocultural variations and consequences for nursing practice were identified. There is a need for continuous advancement in the development of the concept, specific actions to encourage this and the improvement of evaluation methods for its study.

  4. Fluency: an aim in teaching and a criterion in assessment

    Directory of Open Access Journals (Sweden)

    2010-05-01

    Full Text Available This article investigates the concept ‘fluency’ from different perspectives. When fluency is an aim in teaching, a thorough comprehension of the concept among teachers is a prerequisite for appropriate planning of instruction, including the choice of appropriate classroom activities. When fluency is an assessment criterion, it is even more important that examiners have a shared perception of the concept. The present article starts by presenting common perceptions of the concept and goes on to explore some of the current research. Next, it provides a historical overview of the place of fluency in teaching theory and explains some of the preconditions for the inclusion of this concept among teaching objectives and assessment criteria. It will also, as an illustration, give an outline of the position of the concept over time in the Norwegian school system on the basis of an analysis of the relevant syllabuses. Finally, the article explicates the notion of language use as a complex cognitive skill and explores current method¬ological ideas about teaching towards fluency.

    The Nuclear Materials Storage Facility (NMSF) at the Los Alamos National Laboratory (LANL) was a Fiscal Year (FY) 1984 line-item project completed in 1987 that has never been operated because of major design and construction deficiencies. This renovation project, which will correct those deficiencies and allow operation of the facility, is proposed as an FY 97 line item. The mission of the project is to provide centralized intermediate and long-term storage of special nuclear materials (SNM) associated with defined LANL programmatic missions and to establish a centralized SNM shipping and receiving location for Technical Area (TA)-55 at LANL. Based on current projections, existing storage space for SNM at other locations at LANL will be loaded to capacity by approximately 2002. This will adversely affect LANUs ability to meet its mission requirements in the future. The affected missions include LANL's weapons research, development, and testing (WRD ampersand T) program; special materials recovery; stockpile survelliance/evaluation; advanced fuels and heat sources development and production; and safe, secure storage of existing nuclear materials inventories. The problem is further exacerbated by LANL's inability to ship any materials offsite because of the lack of receiver sites for mate rial and regulatory issues. Correction of the current deficiencies and enhancement of the facility will provide centralized storage close to a nuclear materials processing facility. The project will enable long-term, cost-effective storage in a secure environment with reduced radiation exposure to workers, and eliminate potential exposures to the public. This document provides Part I - Design Concept which describes the selected solution, and Part II - Project Management which describes the management system organization, the elements that make up the system, and the control and reporting system

    1996-01-01

    Purpose/Objective: One of the barriers to understanding modern molecular biology is the lack of a clear understanding of the relevant terminology, techniques, and concepts. This refresher course is intended to address these deficiencies starting from a basic level. The lecture will cover many of the common uses of recombinant DNA, including gene cloning and manipulation. The goal is to enable the nonspecialist to increase his or her understanding of molecular biology in order to more fully enjoy reading current publications and/or listening seminars. Radiation biologists trying to understand a little more molecular biology should also benefit. The following concepts will be among those explained and illustrated: restriction endonucleases, gel electrophoresis, gene cloning, use of vectors such as plasmids, bacteriophage, cosmids and viruses, cDNA and genomic libraries, Southern, Northern, and Western blotting, fluorescent in situ hybridization, polymerase chain reaction (PCR), gel retardation, and reporter gene assays

    The world wide web opens up new opportunities to interconnect electronic and classroom teaching and to promote active student participation. In this project article we describe the use of internet discussion forums as part of a student-centred teaching concept of pharmacology and discuss its advantages and disadvantages based on evaluation data and current literature. Final year medical students at the Technische Universität München (Munich, Germany) with the elective pharmacology moderated an internet forum that allowed all students to discuss pharmacology-related questions. Evaluation results of forum participants and elective students demonstrated a learning benefit of internet forums in pharmacology teaching. Internet discussion forums offer an easy-to-implement and effective way to actively engage students and increase the learning benefit of electronic and classroom teaching in pharmacology.

    Public awareness-raising campaigns targeting alcohol use during pregnancy are an important part of preventing prenatal alcohol exposure and Fetal Alcohol Spectrum Disorder. Despite this, there is little evidence on what specific elements contribute to campaign message effectiveness. This research evaluated three different advertising concepts addressing alcohol and pregnancy: a threat appeal, a positive appeal promoting a self-efficacy message, and a concept that combined the two appeals. The primary aim was to determine the effectiveness of these concepts in increasing women's intentions to abstain from alcohol during pregnancy. Women of childbearing age and pregnant women residing in Perth, Western Australia participated in a computer-based questionnaire where they viewed either a control or one of the three experimental concepts. Following exposure, participants' intentions to abstain from and reduce alcohol intake during pregnancy were measured. Other measures assessed included perceived main message, message diagnostics, and potential to promote defensive responses or unintended consequences. The concepts containing a threat appeal were significantly more effective at increasing women's intentions to abstain from alcohol during pregnancy than the self-efficacy message and the control. The concept that combined threat and self-efficacy is recommended for development as part of a mass-media campaign as it has good persuasive potential, provides a balance of positive and negative emotional responses, and is unlikely to result in defensive or unintended consequences. This study provides important insights into the components that enhance the persuasiveness and effectiveness of messages aimed at preventing prenatal alcohol exposure. The recommended concept has good potential for use in a future campaign aimed at promoting women's intentions to abstain from alcohol during pregnancy.

    Psychotherapy is an activity which takes many forms and which has many aims. The present paper argues that it can be viewed as a form of moral suasion. Kant's concepts of free will and ethics are described and these are then applied to the processes and outcome of psychotherapy. It is argued that his ideas, by linking rationality, free will and ethics into a single philosophical system, offer a valuable theoretical framework for thinking about aims and ethical issues in psychotherapy.

    Re-usable and sharable, and therefore language-independent concept models are of increasing importance in the medical domain. The GALEN project (Generalized Architecture for Languages Encyclopedias and Nomenclatures in Medicine) aims at developing language-independent concept representation systems as the foundations for the next generation of multilingual coding systems. For use within clinical applications, the content of the model has to be mapped to natural language. A so-called Multilingual Information Module (MM) establishes the link between the language-independent concept model and different natural languages. This text generation software must be versatile enough to cope at the same time with different languages and with different parts of a compositional model. It has to meet, on the one hand, the properties of the language as used in the medical domain and, on the other hand, the specific characteristics of the underlying model and its representation formalism. We propose a semantic-oriented approach to natural language generation that is based on linguistic annotations to a concept model. This approach is realized as an integral part of a Terminology Server, built around the concept model and offering different terminological services for clinical applications.

    2010-01-01

    Aims: This study explores radiation therapists' understanding and interpretations of the concept of caring within their profession. Background: Health professions' concepts of care have been explored in disciplines such as nursing and medicine. However, there has been little previous attempt to describe what caring means to radiation therapists. Methods: A qualitative phenomenological approach was used and 27 radiation therapists were interviewed in four focus groups. Discussions were transcribed and analysis was performed to identify themes from the data. Results: Three overarching themes emerged from the data: human connection established between radiation therapists and patients, technical care as the use of technology and procedures in treatment planning and delivery, and the therapist's unique identity as compared to other professions. Conclusions: The concept of care was seen by radiation therapists primarily as a supportive relationship with the patient but they were unable to agree if the technical aspects and procedures were considered a part of caring. Further research is needed to further examine the connection between technology and care.

    The current defence-in-depth (DiD) concept has been established by the Reactor Harmonization Working Group (RHWG) of Western European Nuclear Regulators Association (WENRA). Principally the DiD concept was already part of the very early power reactor designs. However, additional considerations have been done in order to take plant conditions into account which are beyond the original design basis. The most recent advancements have been done based on major lessons learned from the Fukushima Dai-Ichi accident. Especially for new nuclear reactors it has to be demonstrated that DiD aspects have been considered in their design. Currently Toshiba is adapting its Advanced Boiling Water Reactor (ABWR) for the European market, at first in Finland. This presentation aims to describe how the new DiD concept has been applied to achieve the safety goals for a modern reactor type and to ensure a design that can be licensed in Western Europe.

    The relative merits of various LWR UO 2 fuel concepts with the potential for improved power-ramping capability were qualitatively assessed. In the evaluation, it was determined that of the various concepts being considered, those that presently possess an adequately developed experience base include annular pellets, cladding coated with graphite on the inner surface, and packed-particle fuel. Therefore, these were selected for initial evaluation as part of the Fuel Performance Improvement Program. For this program, graphite-coated cladding is being used in conjunction with annular pellet fuel as one of the concepts with the anticipation of gaining the advantage of the combined improvements. The report discusses the following: the criteria used to evaluate the candidate fuel concepts; a comparison of the concepts selected for irradiation with the criteria, including a general description of their experience bases; and a general discussion of other candidate concepts, including identifying those which may be considered for out-of-reactor evaluation as part of this program, those for which the results of other programs will be monitored, and those which have been deleted from further consideration at this time

  19. In defence of andragogy. Part 2: An educational process consistent with modern nursing's aims.

    Science.gov (United States)

    Milligan, F

    1997-12-01

    In 1987 the English National Board (1987) made it clear that it supported a move towards an andragogical approach to nurse education. Recently such moves have been questioned as has the validity of andragogy (Darbyshire 1993). In response to such challenges this paper extends some of the arguments made in the article 'In defence of andragogy' (Milligan 1995). It is argued that andragogy provides a framework within which care and other crucial aspects of the nurse-patient/client relationship can be mirrored and thereby facilitated in future practitioners. In the socialization processes inherent in nurse education, care is surely difficult to teach or facilitate unless the philosophy and methods are consistent with such ends. Furthermore, it is frequently argued that as educationalists we need to be consistent in our approach to students with that which we hope to see in their future practice (Bevis & Murray 1990). Andragogy offers a medium through which this can be facilitated. It is essentially a humanistic educational process that values the individual. The power relationship between the educator and student is much more horizontal than is found in the historically common hierarchical educational relationship. An educational process based upon andragogy therefore mirrors important parts of the nurse-patient/client relationship. It offers a theory of education consistent with the aims of modern day nursing practice. We should seek to improve our understanding of andragogy and no longer conceptualize it as one end of a false dichotomy with pedagogy.

    2018-04-01

    This is the second paper of an essay in two parts. The first paper (Part I) is a critical discussion of Mark Risjord's conception of nursing knowledge where I argued against the conception of nursing knowledge as a kind of nursing science. The aim of the present paper (Part II) is to explicate and substantiate the thesis of nursing as a kind of concrete philosophy. My strategy is to elaborate upon certain themes from Wittgenstein's Tractatus in order to canvass a general scheme of philosophy based on a distinction between reality and the world. This distinction will be employed in the appropriation of certain significant features of nursing and nursing knowledge. By elaborating on the contrast between the abstract and the concrete, I will suggest that nursing may be seen as a kind of concrete philosophy, being primarily concerned with reality (and secondarily with the world). This thesis, I will argue, implies that philosophy is the kind of theory that is essential to nursing (which is not so much a theory than a certain kind of activity). © 2017 John Wiley & Sons Ltd.

    Full Text Available Reading act is performed by connected physiological, psychological and cognitive processes. The operations taking place in these processes are expected to continue for life by being developed with certain strategies. A lot of information is gained with reading skill in education life. Therefore, basic concepts that constitute reading education in teaching and improving reading are important for teachers. The aim of this study is to submit information compiled from the literature about reading education process and which basic concepts are used in reading education. While teaching reading from part to whole, from whole to part and interactional approaches are used. From part to whole approach is at the forefront. Then with interactional approach strategies, both code solving and making sense is improved. Teachers should know the characteristics of bouncing, stopping, turning back, and scanning movements of the eye both in code solving and making sense. The teacher should configure the teaching for the students to gain fluid reading elements by making use of reading out and reading silently. After reading act is acquired; good reader characteristics should be gained by improving asking questions, guessing, summarizing, interpretation skills in integrated readings. Reading skill is improved by studies on the text. Therefore, the students should come across texts that are suitable to their levels, textuality and readability criteria. The vocabulary of children should be improved in a planned way with text-based word and meaning studies. Fluid reading, making sense and interpretation skills of children should be pursued with different evaluation types. In the long term, work should be done to make reading a habit for them.

    1992-09-01

    This study is part of the Project on Alternative Systems Study, PASS, with the overall aim to perform a technical/economical ranking of alternative repository concepts and canisters for the final storage of spent nuclear fuel. The comparison should in the first stage separately assess technology in construction and operation, long-term performance and safety, and costs. Three of the repository concepts are assumed to be located at a depth of approximately 500 m in the host rock, KBS-3, Very Long Holes (VLH) and Medium Long Holes (MLH). In the KBS-3 concept the canisters are deposited in vertical deposition holes in a system of parallel storage tunnels. In the VLH concept larger canisters are deposited in long horizontal tunnels. The MLH concept, is an evolution of the two other concepts, with KBS-3 type canisters deposited in horizontal tunnels. Smaller canisters are to be deposited in deep bore holes at a depth between 2000 to 4000 m in the Very Deep Holes (VDH) concept. In all concepts the canisters will be surrounded by a bentonite buffer. The aim of the present study is to analyze and compare the performance and long-term safety of the repository concepts. Only a qualitative comparison of the concepts is made as no calculations of radionuclide releases or dose to man have been performed. The ranking of the repository concepts was carried out by comparing the VDH, VLH and MLH concept with the KBS-3 concept. The performance and long-term safety of the repositories located at 500 m level will be based on a multiple barrier system and the predictions for the concepts will involve similar uncertainties.

  10. In vivo tissue engineering: Part I. Concept genesis and guidelines for its realization.

    Science.gov (United States)

    Zdrahala, R J; Zdrahala, I J

    1999-10-01

    A loss of function of an organ often represents a life-threatening situation. Transplantations are successful, but "replacement" availability, its compatibility with the host, and subsequent healing often pose serious questions. Tissue engineering, where a carefully prepared scaffold is populated, in vitro, by cells to form an artificial organ, addresses some of the problems mentioned above. Trauma associated with the implant introduction to the host often complicates the process. The novel concept of in vivo tissue engineering which is designed to mediate the healing and tissue regeneration process by providing an in vitro formed porous, microcellular scaffold is proposed. The scaffold (part or entire organ) is then populated by cells either spontaneously (the surrounding cells will spread and populate to inhabit the scaffold) or by cellular augmentation (encapsulated cells are delivered to this in statu nascendi scaffold). Minimally traumatic arthroscopic surgery combined with a unique polymer delivery system is envisioned for the introduction of this implant to a site to be repaired. Such an approach will require the formation of polymer in-situ, in a reasonable time. The scaffold-forming polymers will be, in principle, biodegradable. We propose to utilize biodegradable polyurethane systems for in vivo tissue engineering. Diversity of their structure/property relationships, relative "ease" of their preparation, and excellent biocompatibility predetermine polyurethanes to be the materials of choice. This paper describes the genesis of this concept and potentials for its realization. It is intended to initiate and stimulate discussion among the related scientific disciplines to form a basis for this field. The synthesis, application, and biodegradation of selected polyurethanes and variety of its medical utilization will be discussed in upcoming papers.

  11. Enhancing Collaborative and Meaningful Language Learning Through Concept Mapping

    Marriott, Rita De Cássia Veiga; Torres, Patrícia Lupion

    This chapter aims to investigate new ways of foreign-language teaching/learning via a study of how concept mapping can help develop a student's reading, writing and oral skills as part of a blended methodology for language teaching known as LAPLI (Laboratorio de Aprendizagem de LInguas: The Language Learning Lab). LAPLI is a student-centred and collaborative methodology which encourages students to challenge their limitations and expand their current knowledge whilst developing their linguistic and interpersonal skills. We explore the theories that underpin LAPLI and detail the 12 activities comprising its programme with specify reference to the use of "concept mapping". An innovative table enabling a formative and summative assessment of the concept maps is formulated. Also presented are some of the qualitative and quantitative results achieved when this methodology was first implemented with a group of pre-service students studying for a degree in English and Portuguese languages at the Catholic University of Parana (PUCPR) in Brazil. The contribution of concept mapping and LAPLI to an under standing of language learning along with a consideration of the difficulties encountered in its implementation with student groups is discussed and suggestions made for future research.

    In response to a transformational movement in nursing education, faculty across the country are considering changes to curricula and approaches to teaching. As a result, an emerging trend in many nursing programs is the adoption of a concept-based curriculum. As part of the curriculum development process, the selection of concepts, competencies, and exemplars on which to build courses and base content is needed. This article presents a benchmark approach used to validate and finalize concept selection among educators developing a concept-based curriculum for a statewide nursing consortium. These findings are intended to inform other nurse educators who are currently involved with or are considering this curriculum approach. Copyright 2012, SLACK Incorporated.

  13. Everyday life and health concepts among blue-collar female workers in Denmark: implications for health promotion aiming at reducing health inequalities.

    Science.gov (United States)

    Jensen, Jeanette Magne

    2013-06-01

    This article introduces a perspective on the health of women with low levels of education in terms of organisation of their everyday life. The aim is to demonstrate the ways in which the women's concept of health is contingent on the conditions encountered in everyday life. A qualitative study based on interviews with the women forms the basis for the discussion. The analysis shows that the women find it difficult to adopt the official discourse on health and its foundation in a biomedical tradition. The article argues that it is necessary to move away from the educational approach focusing on risk and lifestyle with the goal of regulating individual behaviour. Instead, an approach is suggested which can provide the women with the opportunity to gain control of the everyday health determinants which are normally beyond their immediate reach. This is based on the argument that it is necessary to work with a health promotion and education strategy capable of operating within the various interactive patterns between 'environment' and 'individual' which form the foundation for health.

  14. Determination of the Concepts "Profession" and "Role" in Relation to "Nurse Educator".

    Pennbrant, Sandra

    The aim of this study was to clarify the meanings and dimensions of the concepts "profession" and "role." The results from the concept determination were discussed in relation to the profession "nurse educator." This study is based on Koort's semantic analysis methods, using select parts of Eriksson's approach for concept determination, using dictionaries published between the years 1948 and 2015. The findings underline the complexity of the professional role of nurse educators. The nurse educator profession is based on society's trust and requires integration of ability, attitudes, norms, reflection, and theoretical knowledge, along with individual, organizational, and social conditions. Nurse educators must achieve a sufficient degree of pedagogical competence, subject competence, social competence and organizational competence in order to develop their professional role. When nurse educators define their function, a professional role takes form. Copyright © 2016 Elsevier Inc. All rights reserved.

    Simulation test, hardware test and behavioral comparison test are proposed to experimentally verify whether a technical control concept for limb movements is logically precise, physically sound, and biologically relevant. Thereby, robot test-beds may play an integral part by mimicking functional limb movements. The procedure is exemplarily demonstrated for human aiming movements with the forearm: when comparing competitive control concepts, these movements are described best by a spring-like operating muscular-skeletal device which is assisted by feedforward control through an inverse internal model of the limb--without regress to a forward model of the limb. In a perspective on hopping, the concept of exploitive control is addressed, and its comparison to concepts derived from classical control theory advised.

    Full Text Available The way one conceives disabled people seems to influence the actions directed toward them. Occupational therapists constitute a part of health professionals that direct their actions based on a comprehensive view of disability. The aim of this study was to identify and analyze the conception of disability from the standpoint of occupational therapists. Fifteen university teachers of Occupational Therapy undergraduate courses participated in this study: seven from public universities and eight from private institutions, located in mid-sized municipalities in the state of São Paulo. The data were collected by means of a scale denominated “Escala de Avaliação da Concepção de Deficiência” (Rating Scale for Conception of Disability. The results show that the subjects tend to follow interactional, social conceptions of disability. This study yields contributions to understand the conception of disability held by teachers of Occupational Therapy. This conception certainly guides their teaching performance and affects the training of future professionals.

    Full Text Available Background: Clinical reasoning plays an important role in the ability of physicians to make diagnoses and decisions. It is considered the physician’s most critical competence, but it is an ambiguous conceptin medicine that needs a clear analysis and definition. Our aim was to clarify the concept of clinical reasoning in medicine by identifying its components and to differentiate it from other similar concepts.It is necessary to have an operational definition of clinical reasoning, and its components must be precisely defined in order to design successful interventions and use it easily in future research.Methods: McKenna’s nine-step model was applied to facilitate the clarification of the concept of clinical reasoning. The literature for this concept analysis was retrieved from several databases, including Scopus, Elsevier, PubMed, ISI, ISC, Medline, and Google Scholar, for the years 1995– 2016 (until September 2016. An extensive search of the literature was conducted using the electronic database. Accordingly, 17 articles and one book were selected for the review. We applied McKenna’s method of concept analysis in studying clinical reasoning, so that definitional attributes, antecedents, and consequences of this concept were extracted.Results: Clinical reasoning has nine major attributes in medicine. These attributes include: (1 clinical reasoning as a cognitive process; (2 knowledge acquisition and application of different types of knowledge; (3 thinking as a part of the clinical reasoning process; (4 patient inputs; (5 contextdependent and domain-specific processes; (6 iterative and complex processes; (7 multi-modal cognitive processes; (8 professional principles; and (9 health system mandates. These attributes are influenced by the antecedents of workplace context, practice frames of reference, practice models of the practitioner, and clinical skills. The consequences of clinical reasoning are the metacognitive improvement of

Adopts from the concept of the most serious crime in Rome Statute and adjusted with the Indonesian legal system. Then it developed wider and introduced into terrorism, corruption, drug abuse offenses, and child sexual abuse in legislations and Constitutional Court verdicts. The implementation of this concept generated some consequences in drafting and formulating the legislation as part of penal policy. This leads to two legal problems; first, what was the categorization of the concept of extraordinary crime? and second, what were the consequences of the concept extraordinary crime in accordance with penal policy?. Normative law research with literature study method, This was a conducted as the response of both legal problems. Using secondary data from legislation, Constitutional Court verdicts, book and journal, this research concludes that; the concept of extraordinary crime parts of criminal policy does not have any standard for the categorization. Then, as consequences of the implementation of the concept of extraordinary crime in several penal efforts are formulating in legislations. The penalty effort is not limited to criminalization and sentencing aspects but wider and shall be in line with the strategy of crime eradication and welfare protection purposes. To reach the effectiveness of the criminal policy of the concept of extraordinary crime, the penalty effort shall be in line with criminal law principles and human right basic principles.

  4. Current and future competitiveness of bioenergy - Conceptions about competitiveness

    Ling, E.; Lundgren, K.; Maartensson, Kjell

    1998-01-01

    It is important to visualize the conceptions that guide the behaviour of the actors within the energy system to be able to, in an efficient manner, increase the share of renewable energy in the energy mix. A major issue is to elucidate explicit and implicit presumptions within judgements on the competitiveness of bioenergy. This study focuses on how conceptions of bioenergy in the form of patterns of thinking, influence whether bioenergy can become competitive. The aim of the study is to develop a framework that will enable an increased understanding of the competitiveness of bioenergy today and in the future. The conceptions that the actors of the energy system uphold are studied and analysed. The conceptions of the actors are seen as key factors for the understanding of the function of the energy system and accordingly also for the understanding of the competitiveness of bioenergy. The over-all method perspective in the study is an actor approach. The actors' conceptions have been identified from interviews with 30 significant actors within the energy system. The material from the interviews has been synthesised into nine ideal types of actors. These nine 'model actors' are seen as representing the whole material and form the basis for the further analysis of the competitiveness of bioenergy as depending on patterns of thinking called logics. Three idealized logics are developed. The three logics developed in the study are production logic, market logic and socio-economic logic. (Upholders of the logics rank energy sources after production cost, profitability, and socio-economic legitimacy, respectively.) The logics co-exist within the different parts of the energy system. A single person can even uphold more than one logic. The three logics have however different weight in different organisations and in different parts of the energy system. Finally, the study proposes an enlarged description of the competitiveness of bioenergy in three dimensions: price

  6. Current concepts and controversies on adolescent idiopathic scoliosis: Part I

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Adolescent idiopathic scoliosis is the most common spinal deformity encountered by General Orthopaedic Surgeons. Etiology remains unclear and current research focuses on genetic factors that may influence scoliosis development and risk of progression. Delayed diagnosis can result in severe deformities which affect the coronal and sagittal planes, as well as the rib cage, waistline symmetry, and shoulder balance. Patient′s dissatisfaction in terms of physical appearance and mechanical back pain, as well as the risk for curve deterioration are usually the reasons for treatment. Conservative management involves mainly bracing with the aim to stop or slow down scoliosis progression during growth and if possible prevent the need for surgical treatment. This is mainly indicated in young compliant patients with a large amount of remaining growth and progressive curvatures. Scoliosis correction is indicated for severe or progressive curves which produce significant cosmetic deformity, muscular pain, and patient discontent. Posterior spinal arthrodesis with Harrington instrumentation and bone grafting was the first attempt to correct the coronal deformity and replace in situ fusion. This was associated with high pseudarthrosis rates, need for postoperative immobilization, and flattening of sagittal spinal contour. Segmental correction techniques were introduced along with the Luque rods, Harri-Luque, and Wisconsin systems. Correction in both coronal and sagittal planes was not satisfactory and high rates of nonunion persisted until Cotrel and Dubousset introduced the concept of global spinal derotation. Development of pedicle screws provided a powerful tool to correct three-dimensional vertebral deformity and opened a new era in the treatment of scoliosis.

    The concept 'environment' is of considerable importance in present-day engineering thermodynamics. Introduction of this concept in operation brings not only simplification of the methods of solving classical thermodynamic problems, but also gives the exergy method which forms the major new part of thermodynamics, including some parts of biology, economics and other fields of science. But practice shows that it is necessary to define the concept 'environment' more precisely in some cases

  10. Sexual Orientation as Interpretation? Sexual Desires, Concepts, and Choice

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available Are sexual orientations freely chosen? The idea that someone’s sexual orientation is not a choice is very influential in the mainstream LGBT political movement. But do we have good reasons to believe it is not a choice? Going against the orthodoxy, William Wilkerson has recently argued that sexual orientation is partly constituted by our interpretations of our own sexual desires, and we choose these interpretations, so sexual orientation is partly constituted by choice. In this paper I aim to examine the question of whether our interpretations of our own sexual desires are constitutive of our sexual orientations. I will argue that whereas Wilkerson’s argument for the claim that sexual orientations are in part constituted by our chosen interpretations of our sexual desires is not sound, there are good reasons for endorsing a weaker claim, namely, that there are different but equally apt descriptions of the same sexual desires, depending on which concepts we have.

    Full Text Available This first part of the study introduces an elementary concept of information. Our interest for newness, our curiosity in the new, will be considered as a main building block of information, and of reality itself. A typical definition of information (the reduction of uncertainty needs to be fundamentally inverted: Information is a compositional activity, including the inconsistent, the paradox, the contradiction and the incoherent meaning. This study expands on the analysis of the composition of new structure (new macrophysical laws, and the analysis of the causality and causal state of such structures (“causally active symbols”. The classical, scientific-objective, passive understanding of information gives meaning to the fact that modern information technology does not by itself lead to an increase of human values. However, our social and moral stance is an informational one, and our informational, active conscious process holds the power to mediate and to enforce this process towards an enriched life. The indicator for such enrichment is given to us by information, and the knowledge about this process will feed us with energy to move towards an active spirit of ethics, and towards the information society. Part I of this study expands on the fundament basis and on our intrinsic responsibility to release the forces that are based on the active dimension of information. Those forces are required in order to reveal the so-called information society from its metaphorical character (Part II.

    2018-02-01

    In recent years, multilabel classification has attracted significant attention in multimedia annotation. However, most of the multilabel classification methods focus only on the inherent correlations existing among multiple labels and concepts and ignore the relevance between features and the target concepts. To obtain more robust multilabel classification results, we propose a new multilabel classification method aiming to capture the correlations among multiple concepts by leveraging hypergraph that is proved to be beneficial for relational learning. Moreover, we consider mining feature-concept relevance, which is often overlooked by many multilabel learning algorithms. To better show the feature-concept relevance, we impose a sparsity constraint on the proposed method. We compare the proposed method with several other multilabel classification methods and evaluate the classification performance by mean average precision on several data sets. The experimental results show that the proposed method outperforms the state-of-the-art methods.

    This paper reviews research results obtained from Einsteinian physics programs run by different instructors with Years 6, 9, 10 and 11 students using the models and analogies described in parts 1 and 2. The research aimed to determine whether it is possible to teach Einsteinian physics and to measure the changes in student attitudes to physics engendered by introducing the modern concepts that underpin technology today. Results showed that students easily coped with the concepts of Einsteinian physics, and considered that they were not too young for the material presented. Importantly, in all groups, girls improved their attitude to physics considerably more than the boys, generally achieving near parity with the boys.

    Lund, Mikkel N.; Reese, Daniel R.

    The goal of aims (Asteroseismic Inference on a Massive Scale) is to estimate stellar parameters and credible intervals/error bars in a Bayesian manner from a set of asteroseismic frequency data and so-called classical constraints. To achieve reliable parameter estimates and computational efficiency, it searches through a grid of pre-computed models using an MCMC algorithm—interpolation within the grid of models is performed by first tessellating the grid using a Delaunay triangulation and then doing a linear barycentric interpolation on matching simplexes. Inputs for the modelling consist of individual frequencies from peak-bagging, which can be complemented with classical spectroscopic constraints. aims is mostly written in Python with a modular structure to facilitate contributions from the community. Only a few computationally intensive parts have been rewritten in Fortran in order to speed up calculations.

  18. 'Who Thinks Abstractly?': Quantum Theory and the Architecture of Physical Concepts

    International Nuclear Information System (INIS)

    Plotnitsky, Arkady

    2011-01-01

    Beginning with its introduction by W. Heisenberg, quantum mechanics was often seen as an overly abstract theory, mathematically and physically, vis-a-vis classical physics or relativity. This perception was amplified by the fact that, while the quantum-mechanical formalism provided effective predictive algorithms for the probabilistic predictions concerning quantum experiments, it appeared unable to describe, even by way idealization, quantum processes themselves in space and time, in the way classical mechanics or relativity did. The aim of the present paper is to reconsider the nature of mathematical and physical abstraction in modern physics by offering an analysis of the concept of ''physical fact'' and of the concept of 'physical concept', in part by following G. W. F. Hegel's and G. Deleuze's arguments concerning the nature of conceptual thinking. In classical physics, relativity, and quantum physics alike, I argue, physical concepts are defined by the following main features - 1) their multi-component multiplicity; 2) their essential relations to problems; 3) and the interactions between physical, mathematical, and philosophical components within each concept. It is the particular character of these interactions in quantum mechanics, as defined by its essentially predictive (rather than descriptive) nature, that distinguishes it from classical physics and relativity.

  19. Defining the Bobath concept using the Delphi technique.

    Science.gov (United States)

    Raine, Sue

    2006-03-01

    The Bobath concept, based on the work of Berta and Karel Bobath, offers therapists working in the field of neurological rehabilitation a framework for their clinical interventions. It is the most commonly used approach in the UK. Although they recognize that over the last half-century the concept has undergone considerable developments, proponents of the Bobath concept have been criticized for not publishing these changes. The aim of the present study was to use the Delphi technique to enable experts in the field to define the current Bobath concept. A four-round Delphi study design was used. The sample included all members of the British Bobath Tutor's Association, who are considered experts in the field. Initial statements were identified from the literature, with respondents generating additional statements during the study. The level of agreement was determined using a five-point Likert scale. The respondents were then provided with feedback on group opinions and given an opportunity to re-rate each statement. The level of group consensus was set at 80%. Fifteen experts took part. The response rate was 85% in the first round, and 93% in each subsequent round. Ten statements from the literature were rated with a further 12 generated by the experts. Thirteen statements achieved consensus for agreement and seven for disagreement. The Delphi study was an effective research tool, maintaining anonymity of responses and exploring expert opinions on the Bobath concept. The experts stated that Bobath's work has been misunderstood if it is considered as the inhibition of spasticity and the facilitation of normal movement, as described in some literature. They agreed that the Bobath concept was developed by the Bobaths as a living concept, understanding that as therapists' knowledge base grows their view of treatment broadens.

    2015-11-01

    Full Text Available Being sensitive to the challenges placed before us in a globalizing world, it is obviously that the ethical benchmark became one of the priorities in our individual and communitarian life. An in-depth knowledge of both the axiological and normative dimensions of ethics can open an important way for an adequate approach of today’s problems. By rethinking the foundations, we may reach accuracy as regards what does really matter in life. So, a call to revive some value-laden concepts coming from the ancient Greek moral philosophy represents the aim of this paper, to emphasize the support given us by healthy roots for reflection and understanding, in part at least, our present problematic situation in the world.

  9. Concepts for reducing nuclear utility inventory carrying costs

    International Nuclear Information System (INIS)

    Graybill, R.E.; DiCola, F.E.; Solanas, C.H.

    1985-01-01

    Nuclear utilities are under pressure to reduce their operating and maintenance expenses such that the total cost of generating electricity through nuclear power remains an economically attractive option. One area in which expenses may be reduced is total inventory carrying cost. The total inventory carrying cost consists of financing an inventory, managing the inventory, assuring quality, engineering of acceptable parts specifications, and procuring initial and replenishment stock. Concepts and methodology must be developed to reduce the remaining expenses of a utility's total inventory carrying cost. Currently, two concepts exist: pooled inventory management system (PIMS), originally established by General Electric Company and a group of boiling water reactor owners, and Nuclear Parts Associates' (NUPA) shared inventory management program (SIMP). Both concepts share or pool parts and components among utilities. The SIMP program objectives and technical activities are summarized

    2018-05-01

    This research is aimed to analyse students’ conceptions on several electricity concept. This is a descriptive research with the subjects of new students of Sebelas Maret University. The numbers of the subject were 279 students that consisted of several departments such as science education, physics education, chemistry education, biology education and mathematics education in the academic year of 2017/2018. The instrument used in this research was the multiple-choice test with arguments. Based on the result of the research and analysis, it can be concluded that most of the students still find misconceptions and do not understand electricity concept on sub-topics such as electric current characteristic in the series and parallel arrangement, the value of capacitor capacitance, the influence of the capacitor charge and discharge towards the loads, and the amount of capacitor series arrangement. For the future research, it is suggested to improve students’ conceptual understanding with appropriate learning method and assessment instrument because electricity is one of physics material that closely related with students’ daily life.

    2016-01-01

    The purpose of this study was to examine what kinds of conceptions of entrepreneurial learning engineering students expressed in an entrepreneurship course integrated in their study programme. The data were collected during an entrepreneurship course in Estonia that was organised for fourth-year engineering students, using video-recorded group interviews (N = 48) and individual in-depth interviews (N = 16). As a result of the phenomenographic analysis, four qualitatively distinctive conceptions of entrepreneurial learning were discerned. Entrepreneurial learning was seen to involve (1) applying entrepreneurial ideas to engineering, (2) understanding entrepreneurial issues in a new way, (3) action-oriented personal development, and (4) self-realising through collective effort. These qualitatively distinct categories differed from each other in four dimensions of variation: nature of learning, response to pedagogy, relation to teamwork, and learning outcomes.

    Reflexology is basically a study of how one part of the human body relates to another part of the body. Reflexology practitioners rely on the reflexes map of the feet and hands to all the internal organs and other human body parts. They believe that by applying the appropriate pressure and massage certain spots on the feet and hands, all other body parts could be energized and rejuvenated. This review aimed to revisit the concept of reflexology and examine its effectiveness, practices, and the training for reflexology practitioners. PubMed, SCOPUS, Google Scholar, and SpringerLink databases were utilized to search the following medical subject headings or keywords: foot massage, reflexology, foot reflexotherapy, reflexological treatment, and zone therapy. The articles published for the last 10 years were included. Previous systematic reviews failed to show concrete evidence for any specific effect of reflexology in any conditions. Due to its non-invasive, non-pharmacological complementary nature, reflexology is widely accepted and anecdotal evidence of positive effect reflexology in a variety of health conditions are available. Adequate training for practitioners is necessary to ensure the consistency of service provided.

    Full Text Available Mediatization has become increasingly a key concept, fundamental, essential to describe the present and the history of media and communicative change taking place. Thus, it became part of a whole, one can not see them as a separate sphere. In this perspective, the media coverage is used as a concept to describe the process of expansion of the different technical means and consider the interrelationships between the communicative change, means and sociocultural change. However, although many researchers use the concept of mediatization, each gives you the meaning that best suits your needs. Thus, the concept of media coverage is treated with multiple voices. This paper discusses this problem and present a preliminary pre-position on the matter.

    the concept of 'advanced midwifery practice' is explored to a limited extent in the international literature. However, a clear conception of advanced midwifery practice is vital to advance the discipline and to achieve both internal and external legitimacy. This concept analysis aims to clarify advanced midwifery practice and identify its components. a review of the literature was executed using Rodgers' evolutionary method of concept analysis to analyze the attributes, references, related terms, antecedents and consequences of advanced midwifery practice. an international consensus definition of advanced midwifery practice is currently lacking. Four major attributes of advanced midwife practitioners (AMPs) are identified: autonomy in practice, leadership, expertise, and research skills. A consensus was found on the need of preparation at master's level for AMPs. Such midwives have a broad and internationally varied scope of practice, fulfilling different roles such as clinicians, clinical and professional leaders, educators, consultants, managers, change agents, researchers, and auditors. Evidence illustrating the important part AMPs play on a clinical and strategic level is mounting. the findings of this concept analysis support a wide variety in the emergence, titles, roles, and scope of practice of AMPs. Research on clinical and strategic outcomes of care provided by AMPs supports further implementation of these roles. As the indistinctness of AMPs' titles and roles is one of the barriers for implementation, a clear conceptualization of advanced midwifery practice seems essential for successful implementation. an international debate and consensus on the defining elements of advanced midwifery practice could enhance the further development of midwifery as a profession and is a prerequisite for its successful implementation. Due to rising numbers of AMPs, extension of practice and elevated quality requirements in healthcare, more outcomes research exclusively

    1996-01-01

    There are principle drawbacks of any kind of solid nuclear fuel listed and analyzed in the first part of the paper. One of the primary results of the analyses performed shows that the solid fuel concept, which was to certain degree advantageous in the first periods of a nuclear reactor development and operation, has guided this branch of a utilization of atomic nucleus energy to a death end. On the background of this, the liquid fuel concept and its benefits are introduced and briefly described in the first part of the paper, too. As one of the first realistic attempts to utilize the advantages of liquid fuels, the reactor/blanket system with molten fluoride salts in the role of fuel and coolant simultaneously, as incorporated in the accelerator-driven transmutation technology (ADTT) being proposed and currently having been under development in the Los Alamos National Laboratory, will be studied both theoretically and experimentally. There is a preliminary design concept of an experimental assembly LA-O briefly introduced in the paper which is under preparation in the Czech Republic for such a project. Finally, there will be another very promising concept of a small low power ADTT system introduced which is characterized by a high level of safety and economical efficiency. In the conclusion, the overall survey of principal benefits which may be expected by introducing liquid nuclear fuel in nuclear power and research reactor systems is given and critically analyzed. 7 refs, 4 figs

    Purpose: This paper presents an overview of multisource inverse-geometry computed tomography (IGCT) as well as the development of a gantry-based research prototype system. The development of the distributed x-ray source is covered in a companion paper [V. B. Neculaes et al., “Multisource inverse-geometry CT. Part II. X-ray source design and prototype,” Med. Phys. 43, 4617–4627 (2016)]. While progress updates of this development have been presented at conferences and in journal papers, this paper is the first comprehensive overview of the multisource inverse-geometry CT concept and prototype. The authors also provide a review of all previous IGCT related publications. Methods: The authors designed and implemented a gantry-based 32-source IGCT scanner with 22 cm field-of-view, 16 cm z-coverage, 1 s rotation time, 1.09 × 1.024 mm detector cell size, as low as 0.4 × 0.8 mm focal spot size and 80–140 kVp x-ray source voltage. The system is built using commercially available CT components and a custom made distributed x-ray source. The authors developed dedicated controls, calibrations, and reconstruction algorithms and evaluated the system performance using phantoms and small animals. Results: The authors performed IGCT system experiments and demonstrated tube current up to 125 mA with up to 32 focal spots. The authors measured a spatial resolution of 13 lp/cm at 5% cutoff. The scatter-to-primary ratio is estimated 62% for a 32 cm water phantom at 140 kVp. The authors scanned several phantoms and small animals. The initial images have relatively high noise due to the low x-ray flux levels but minimal artifacts. Conclusions: IGCT has unique benefits in terms of dose-efficiency and cone-beam artifacts, but comes with challenges in terms of scattered radiation and x-ray flux limits. To the authors’ knowledge, their prototype is the first gantry-based IGCT scanner. The authors summarized the design and implementation of the scanner and the authors presented

    Full Text Available The kinematics concept test (KCT is a multiple-choice test designed to evaluate students’ conceptual understanding of kinematics at the high school level. The test comprises 49 multiple-choice items about velocity and acceleration, which are based on seven kinematic concepts and which make use of three different representations. In the first part of this article we describe the development and the validation process of the KCT. We applied the KCT to 338 Swiss high school students who attended traditional teaching in kinematics. We analyzed the response data to provide the psychometric properties of the test. In the second part we present the results of a structural analysis of the test. An exploratory factor analysis of 664 student answers finally uncovered the seven kinematics concepts as factors. However, the analysis revealed a hierarchical structure of concepts. At the higher level, mathematical concepts group together, and then split up into physics concepts at the lower level. Furthermore, students who seem to understand a concept in one representation have difficulties transferring the concept to similar problems in another representation. Both results have implications for teaching kinematics. First, teaching mathematical concepts beforehand might be beneficial for learning kinematics. Second, instructions have to be designed to teach students the change between different representations.

    To describe ecological farmers' conceptions of healthy eating. Study with a qualitative approach. In January and February 2007, supported by a guide, in-depth interviews were conducted with 11 women and one man who were living in an agricultural community in Rio Branco do Sul, Southern Brazil. The interviewees were selected randomly from among the 20 ecological farming families in this municipality. Three analysis categories were identified: "awareness of healthy eating"; "purchasing power" and "healthy land". The significance of healthy eating for the female farmers involved the idea that foods should be natural, without agricultural pesticides or manufactured chemical products. The daily routine should include abundant consumption of fruits, greens and other vegetables, in addition to the basic rice, beans and meat, and the composition of dishes should aim towards prevention of obesity and chronic-degenerative diseases. Care regarding natural resources in order to ensure production of healthy foods, food safety, environmental sustainability and the future of life on the planet form part of the concept of healthy eating. Knowledge, self-criticism and discernment accompanied the conceptions of healthy eating.

  13. Academic Self-Concept: Modeling and Measuring for Science

    Science.gov (United States)

    Hardy, Graham

    2014-08-01

    In this study, the author developed a model to describe academic self-concept (ASC) in science and validated an instrument for its measurement. Unlike previous models of science ASC, which envisage science as a homogenous single global construct, this model took a multidimensional view by conceiving science self-concept as possessing distinctive facets including conceptual and procedural elements. In the first part of the study, data were collected from 1,483 students attending eight secondary schools in England, through the use of a newly devised Secondary Self-Concept Science Instrument, and structural equation modeling was employed to test and validate a model. In the second part of the study, the data were analysed within the new self-concept framework to examine learners' ASC profiles across the domains of science, with particular attention paid to age- and gender-related differences. The study found that the proposed science self-concept model exhibited robust measures of fit and construct validity, which were shown to be invariant across gender and age subgroups. The self-concept profiles were heterogeneous in nature with the component relating to self-concept in physics, being surprisingly positive in comparison to other aspects of science. This outcome is in stark contrast to data reported elsewhere and raises important issues about the nature of young learners' self-conceptions about science. The paper concludes with an analysis of the potential utility of the self-concept measurement instrument as a pedagogical device for science educators and learners of science.

  14. Aims and theoretical frameworks in nursing students' Bachelor's theses in Sweden: A descriptive study.

    2016-02-01

    Nursing students' independent projects in Sweden not only provide an opportunity to receive a professional qualification as a nurse but also gain a Bachelor's degree in nursing. The aim of these projects is to demonstrate knowledge and understanding within the major field of the education. This study aimed to describe and analyze the topics as well as theoretical frameworks and concepts in nursing students' independent projects, which lead to a Bachelor's degree, in a Swedish context. A total of 491 independent projects, written by nursing students in Sweden, were included in the study. Topics together with theoretical frameworks and concepts in the projects were identified. Similar topics and theoretical frameworks and concepts, respectively, were grouped into subcategories, and similar subcategories were then merged into a main category. The number of entries in each category was counted for descriptive statistics in order to allow for the demonstration of magnitude. The most common topics concerned experiences and managing when having an illness, experiences of care and of being a caregiver, and healthcare staff's care and knowledge. The nursing theories/models that were most often used were Eriksson's Theory of Caritative Caring, Travelbee's Human-to-Human Relationship Model, and Orem's Self-care Theory. Among the non-nursing theories/models, perspectives and concepts lifeworld, ethical values and principles, existential concepts and quality of life/health-related quality of life, were most often used by these students. There may be some difficulty in finding a topic for the project that is relevant for both a professional qualification as a nurse, as well as for achieving the requirements of a Bachelor's degree in nursing. The study indicates that there is a need to widen the student's understanding of different nursing theories/perspectives/models/concepts during nursing education so that students are familiar with a broad range of these when conducting their

    The National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC) is investigating current and anticipated wireless communications concepts and technologies that the National Airspace System (NAS) may need in the next 50 years. NASA has awarded three NASA Research Announcements (NAR) studies with the objective to determine the most promising candidate technologies for air-to-air and air-to-ground data exchange and analyze their suitability in a post-NextGen NAS environment. This paper will present progress made in the studies and describe the communications challenges and opportunities that have been identified as part of the study. NASA's NextGen Concepts and Technology Development (CTD) Project integrates solutions for a safe, efficient and high-capacity airspace system through joint research efforts and partnerships with other government agencies. The CTD Project is one of two within NASA's Airspace Systems Program and is managed by the NASA Ames Research Center. Research within the CTD Project is in support the 2011 NASA Strategic Plan Sub-Goal 4.1: Develop innovative solutions and advanced technologies, through a balanced research portfolio, to improve current and future air transportation. The focus of CTD is on developing capabilities in traffic flow management, dynamic airspace configuration, separation assurance, super density operations and airport surface operations. Important to its research is the development of human/automation information requirements and decisionmaking guidelines for human-human and human-machine airportal decision-making. Airborne separation, oceanic intrail climb/descent and interval management applications depend on location and intent information of surrounding aircraft. ADS-B has been proposed to provide the information exchange, but other candidates such as satellite-based receivers, broadband or airborne internet, and cellular communications are possible candidate's.

    Bjørnskov, Christian; Sønderskov, Kim Mannemar

    The aim of this paper is to explore whether the concept of social capital as popularized by Robert Putnam is a good social science concept. Taken Gerring’s and Adcock and Collier’s work on concept formation and measurement validity as the starting point, the paper first discusses necessary...... conditions for concepts to be good in a strict sense. Afterwards, an empirical section explores the validity of the unidimensionality assumption of most definitions of social capital. This assumption is rejected in four separate tests at both the micro and macro level. A final section therefore discusses...

  18. Spatial Modernist Architectural Artistic Concepts

    Gudkova, T. V.; Gudkov, A. A.

    2017-11-01

    The development of a single spatial modernist conception had continued until the middle of the twentieth century. The first authors who proposed the new conceptual solutions of an architectural space that had the greatest impact on the further development of architecture were Le Corbusier, Frank Lloyd Wright, Mies van der Rohein. They embodied different approaches within the common modernist spatial concept using the language of morphological, symbolic and phenomenological descriptions of space. The concept was based on the simplification of functional links, integration of internal architectural space with the environment due to the vanishing of boundaries between them and expansion of their interrelation. Le Corbusier proposed a spatio-temporal concept based on the movement and tempo-rhythmics of the space “from inside to outside.” Frank Lloyd Wright proposed the concept of integral space where inner and outer spaces were the parts of a whole. Mies van der Rohein was the author of the universal space concept in which the idea of the “dissolution” of the inner space in the outer space was embodied.

  1. Restoration handbook for sagebrush steppe ecosystems with emphasis on greater sage-grouse habitat—Part 1. Concepts for understanding and applying restoration

    Sagebrush steppe ecosystems in the United States currently occur on only about one-half of their historical land area because of changes in land use, urban growth, and degradation of land, including invasions of non-native plants. The existence of many animal species depends on the existence of sagebrush steppe habitat. The greater sage-grouse (Centrocercus urophasianus) is a landscape-dependent bird that requires intact habitat and combinations of sagebrush and perennial grasses to exist. In addition, other sagebrush-obligate animals also have similar requirements and restoration of landscapes for greater sage-grouse also will benefit these animals. Once sagebrush lands are degraded, they may require restoration actions to make those lands viable habitat for supporting sagebrushobligate animals. This restoration handbook is the first in a three-part series on restoration of sagebrush ecosystems. In Part 1, we discuss concepts surrounding landscape and restoration ecology of sagebrush ecosystems and greater sage-grouse that habitat managers and restoration practitioners need to know to make informed decisions regarding where and how to restore specific areas. We will describe the plant dynamics of sagebrush steppe ecosystems and their responses to major disturbances, fire, and defoliation. We will introduce the concepts of ecosystem resilience to disturbances and resistance to invasions of annual grasses within sagebrush steppe. An introduction to soils and ecological site information will provide insights into the specific plants that can be restored in a location. Soil temperature and moisture regimes are described as a tool for determining resilience and resistance and the potential for various restoration actions. Greater sage-grouse are considered landscape birds that require large areas of intact sagebrush steppe; therefore, we describe concepts of landscape ecology that aid our decisions regarding habitat restoration. We provide a brief overview of

    Medical concepts and strategies are permanently changing. Due to the emergency response in a mass casualty incident everyone who is involved has to work together with different organisations and public authorities, which are not part of the regular emergency medical service. Within the last 25 years throughout the whole country of Germany the role of a "chief emergency physician" has been implemented and in preparation for the FIFA World Cup 2006 mobile treatment units were set up. In 2007, special units of the "Medical Task Force" - funded by the german state - were introduced and have been established by now. They will be a permanent part of regional plannings for mass casualty incidents. This article highlights current concepts and developments in different parts of Germany. © Georg Thieme Verlag Stuttgart · New York.

Basic understanding of Biostatistics plays an important role during the entire Evidence-Based Dentistry (EBD) process. This report describes Biostatistics fundamentals in order to introduce the basic concepts used in statistics, such as summary measures, estimation, hypothesis testing, effect size, level of significance, p value, confidence intervals, etc., which are available to Pediatric Dentists interested in reading or designing original clinical or epidemiological studies.

  5. Modern Confucianism and the Concept of “Asian Values”

    2016-02-01

    Full Text Available Through contrastive analysis, the present paper aims to introduce the connections between the now fashionable notion of Asian values and the Modern Confucian discourses. Even though this has often been closely identified with Confucian axiology, this article shows how and why this notion has almost nothing to do with the contemporary stream of the so-called Modern Confucians or their philosophy. However, precisely because of this false identification, and in order to clarify any misunderstandings as to the supposed Confucian roots of this idea, it must be examined in greater detail, and placed in its historical, ideological, and sociological context. Hence, the present paper aims to introduce the difference between Modern Confucian philosophy and the discourse on Asian values, which is often mistakenly comprehended as forming part of Modern Confucianism. Given the prevalence of this confusion, it is important to explain why and in what ways Modern Confucians are, instead, generally critical of the concept of “Asian values”.

    Safety pharmacology (SP) is an essential part of the drug development process that aims to identify and predict adverse effects prior to clinical trials. SP studies are described in the International Conference on Harmonisation (ICH) S7A and S7B guidelines. The core battery and supplemental SP studies evaluate effects of a new chemical entity (NCE) at both anticipated therapeutic and supra-therapeutic exposures on major organ systems, including cardiovascular, central nervous, respiratory, renal and gastrointestinal. This review outlines the current practices and emerging concepts in SP studies including frontloading, parallel assessment of core battery studies, use of non-standard species, biomarkers, and combining toxicology and SP assessments. Integration of the newer approaches to routine SP studies may significantly enhance the scope of SP by refining and providing mechanistic insight to potential adverse effects associated with test compounds.

    2016-09-01

    Full Text Available Despite the urgency and growing interest in a subject, there is no unifying definition of terrorism. A large number of studies could be seen as integral part of ‘counter-terrorism’ strategies- as set of practices to prevent and defeat terrorism. Lisa Stampnitzky’s research looked into the discourse of terrorism experts and argued that the concept of terrorism is a social construct, thus revealing further structure that facilitated it. Aim of this paper is to compare the concept of terrorism as media discourse- a form of legitimate expert interpretation, with conspiracy theory as a form of illegitimate, para-institutional form of interpretation. Noting the commonplaces of the two: defined as an afterthought, both being designated and not self-described notions, featuring a plot that precedes the event- this paper will look at these discourses, the way they relate to (and intersect each other, and try to trace their manifestations.

    2018-05-01

    Full Text Available In the modern era of internationalization, interconnection and rapid technological changes the obligation of the public sector to provide the best possible services to citizens have become challenging tasks. The incorporation of Total Quality Management principles and tools in public services can prove to be decisive given that they contribute to the improvement of the services provided, offer better customer service, help in understanding how the agency is organised and operates, as well as contribute in changing the attitude of employees towards the adoption of a quality culture. Since the mid-00’s, several programmes have been implemented in Greece in order to improve the quality of public services which was, up to that point, dictated only by the need to consolidate relative EU financial resources. This paper is the first part of a study about the application of principal management concepts in Greek public sector since year 2004 when Law 3230/2004 was introduced. In particular it tries to record and assess the experience of the implementation of the “Common Assessment Framework” in Greek public services. Towards this end, the views and opinions of experts from the public sector are analysed with the use of interviews and questionnaires.

  10. Self-care Concept Analysis in Cancer Patients: An Evolutionary Concept Analysis

    Hasanpour-Dehkordi, Ali

    2016-01-01

    Background: Self-care is a frequently used concept in both the theory and the clinical practice of nursing and is considered an element of nursing theory by Orem. The aim of this paper is to identify the core attributes of the self-care concept in cancer patients. Materials and Methods: We used Rodgers’ evolutionary method of concept analysis. The articles published in English language from 1980 to 2015 on nursing and non-nursing disciplines were analyzed. Finally, 85 articles, an MSc thesis, and a PhD thesis were selected, examined, and analyzed in-depth. Two experts checked the process of analysis and monitored and reviewed the articles. Results: The analysis showed that self-care concept is determined by four attributes of education, interaction, self-control, and self-reliance. Three types of antecedents in the present study were client-related (self-efficacy, self-esteem), system-related (adequate sources, social networks, and cultural factors), and healthcare professionals-related (participation). Conclusion: The self-care concept has considerably evolved among patients with chronic diseases, particularly cancer, over the past 35 years, and nurses have managed to enhance their knowledge about self-care remarkably for the clients so that the nurses in healthcare teams have become highly efficient and able to assume the responsibility for self-care teams.

    2013-01-01

    Since Fukushima, there has been intensive work on earthquake safety in all nuclear power plants. A large part of these efforts aim at the earthquake safety of safety-relevant pipeline systems. The problem with earthquake safety here is not the pipeline system itself but rather its mountings and connections to components. This is precisely the topic that the KAE dealt with in years of research and development work. It has developed an algorithm that determines the optimal mounting concept with a few iteration steps depending on arbitrary combinations of loading conditions whilst maintaining compliance with relevant regulations for any pipeline systems. With this tool at hand, we are now in a position to plan and realise remedial measures accurately with minimum time and hardware expenditure, and so distinctly improve the earthquake safety of safety-relevant systems.

    Self-esteem is an inner attitude at the base of the construction of personality and psychic balance in addition to be responsible of adaptive processes over the course of life. The concept of self-esteem is commonly used in several disciplines however, it seems that the consensus on its conceptualization and its operationalization is not yet reached. In this context, the concept analysis allows to address a phenomenon and to understand its use and its evolution from a unique disciplinary perspective. The aim of this article is therefore to analyze the concept of self esteem from a nursing perspective to identify : definitions of the term and related terms, attributes, model and limit cases proposed here within the community of mental health nurses, antecedents and consequents as well as the empirical references using the Walker and Avant method. The attributes identified allowing a deeper understanding of the concept are : the self-value, the self-acceptance, the self-efficacy, attitude towards oneself and finally, self-respect.

  15. The generative basis of natural number concepts.

    Science.gov (United States)

    Leslie, Alan M; Gelman, Rochel; Gallistel, C R

    2008-06-01

    Number concepts must support arithmetic inference. Using this principle, it can be argued that the integer concept of exactly ONE is a necessary part of the psychological foundations of number, as is the notion of the exact equality - that is, perfect substitutability. The inability to support reasoning involving exact equality is a shortcoming in current theories about the development of numerical reasoning. A simple innate basis for the natural number concepts can be proposed that embodies the arithmetic principle, supports exact equality and also enables computational compatibility with real- or rational-valued mental magnitudes.

    The aim of this article is to analyze the concept of respite care in the context of caring for a child with special healthcare needs. Respite care has often been identified as an important resource for caregivers of children with special healthcare needs. It can help provide a break from the constant demands of caregiving. A concept analysis was conducted using an evolutionary approach. The data source for the concept analysis was a review of literature addressing respite care for caregivers of children with special healthcare needs. A review of the literature was conducted and a concept model was developed using an evolutionary approach. A theoretical definition of respite care is provided and the defining attributes, related concepts, antecedents, and consequences of respite care are shown in a diagram of the concept of respite care. The conceptual model provides a framework to help nurses better understand the concept of respite care in order to educate caregivers, provide appropriate referrals, serve as providers of respite care, and advocate for policy changes related to the provision of respite care services for caregivers of children with special healthcare needs. © 2016 Wiley Periodicals, Inc.

    AIM The aim of this article was to analyze the concept of caregiver stress in the context of caring for a person with Alzheimer’s disease and related dementias. BACKGROUND Currently, there are more than 15 million unpaid care-givers for persons suffering from Alzheimer’s disease and related dementias. This unpaid care can be stressful for caregivers due to the chronic nature of the disease process, as well as other factors. METHOD The paper incorporates the modified method of Wilson’s concept analysis procedure to analyze the concept of caregiver stress. DATA SOURCES A review of the literature was undertaken using the Cumulative Index to Nursing and Allied Health Literature, Google Scholar, and PubMed. RESULTS A theoretical definition of caregiver stress is provided, and the defining attributes, related concepts, antecedents, and consequences of caregiver stress are proposed, and case studies are presented. CONCLUSIONS The analysis demonstrates that caregiver stress is the unequal exchange of assistance among people who stand in close relationship to one another, which results in emotional and physical stress on the caregiver. Implications for future nursing research and practice conclude the paper. PMID:24787468

    2018-01-01

    The aim of this article is to provide clarity of the concept of health habit. Using Walker and Avant's (1983; 2010) method for conducting a concept analysis, the authors identify the attributes and characteristics of health habit, its theoretical and practical application to nursing, and sample cases to further illustrate the concept. Empirical and conceptual literature was used to inform this concept analysis. Articles and one book from 1977 to 2014 were reviewed from PsycINFO, Medline, Cumulative Index to Nursing Health Literature (CINAHL), Science Direct, EBSCOhost and Web of Science. Offering a clear definition and conceptual model of health habit provide the foundation to identify/develop appropriate measures of the concept and guide further investigation of understanding the development and sustainability of healthy habits. Additional research is needed to test the conceptual relationships between health habits and outcome variables as they apply to different groups across the age continuum. © 2017 Wiley Periodicals, Inc.

    In quadruple isotropic (QUADRISO) coated particles, a burnable absorber layer surrounds the fuel kernel; consequently, during irradiation, the poison depletion allows more neutrons to stream into the kernel and to produce more fission reactions that attenuate the reactivity loss due to fuel depletion. In our previous studies, we have proposed for the first time the novel concept of QUADRISO particles for managing the long term excess of reactivity and we have shown in details how the new concept flattens the reactivity curve as function of time compared to traditional designs of burnable absorbers. In the present study, we apply the new concept of QUADRISO particles for transmuting Light Water Reactors waste in a prismatic high temperature reactor. We simulated two irradiation periods of 500 and 200 days that allow to transmute over 95% and 52% of {sup 239}Pu and actinides, respectively, without any reprocessing of the irradiated fuel in-between. During the first irradiation period the high initial excess of reactivity is managed by the QUADRISO particles; during the second irradiation period, there is no need of QUADRISO particles because of the small initial fissile inventory in the core.

    In quadruple isotropic (QUADRISO) coated particles, a burnable absorber layer surrounds the fuel kernel; consequently, during irradiation, the poison depletion allows more neutrons to stream into the kernel and to produce more fission reactions that attenuate the reactivity loss due to fuel depletion. In our previous studies, we have proposed for the first time the novel concept of QUADRISO particles for managing the long term excess of reactivity and we have shown in details how the new concept flattens the reactivity curve as function of time compared to traditional designs of burnable absorbers. In the present study, we apply the new concept of QUADRISO particles for transmuting Light Water Reactors waste in a prismatic high temperature reactor. We simulated two irradiation periods of 500 and 200 days that allow to transmute over 95% and 52% of 239 Pu and actinides, respectively, without any reprocessing of the irradiated fuel in-between. During the first irradiation period the high initial excess of reactivity is managed by the QUADRISO particles; during the second irradiation period, there is no need of QUADRISO particles because of the small initial fissile inventory in the core

    The Dual Fluid Reactor is a molten salt fast reactor developed by IFK in Berlin based on the Gen-IV Molten-Salt Reactor concept and the Liquid-Metal Cooled Reactor. The design aims to combine these two concepts to improve these two concepts. The Dissertation focuses on the concept and performs diverse calculations and estimations on the subjects of neutron physics, depletion and thermal-hydraulic behaviors to validate the new features of the concept. Based on the results it is concluded that this concept is feasible to its desired purpose and with great potential.

  3. CONCEPT OF "TRUTH" IN THE NOVEL OF MIKHAIL BULGAKOV'S MASTER AND MARGARITA

    Full Text Available The subject of our study was the concept of "truth" in Bulgakov's novel Master and Margarita. S. Stepanov gave the defi nition of a concept. The concept is like a clot of culture in human consciousness; that is the manner, in which culture becomes a part of the mental world of a man. And, on the other hand, the concept is a way for a man as an ordinary, normal person, not a "creator of cultural values" to be included in the culture, and in some cases, to affects it. In the analysis of the concept of "truth" we start from its cultural-and-etymological understanding of the word "truth". The aim of the study was to conduct a comparative analysis of the three editions of the novel and to fi nd out what semantic meanings Bulgakov deals with in a particular case and how it aff ects the transformation of the idea of the novel from edition to edition.Three editions of the novel were the material for the research: the first is "Engineer Hoof " (1930–1932, the second is Grand Chancellor (1932–1934 and the fi nal version of "The Master and Margarita." In these three editions Yeshua involves everyone who he is talking to in the dialogue. In the editions Engineer Hoof and Grand Chancellor M. A. Bulgakov uses the concept of "truth" in scientific- philosophical and sacred meanings (plans. In the final text Yeshua appears as a philosopher who is in search of the truth.

    High-resolution magnetic resonance imaging (MRI) is recommended for the evaluation of metastatic risk factors in children with retinoblastoma according to recent guidelines. The aim of this study was to compare diagnostic accuracy of a new imaging concept with two orbit surface coils to that of an old imaging concept with one orbit surface coil. One hundred forty-three patients (148 eyes, 64 girls, 79 boys) underwent high-resolution MRI on 1.5 T scanners using orbit surface coils. The old imaging concept (one orbit surface coil focusing on the (most) effected eye additionally to the standard head coil) was used in 100 patients/103 eye; the new imaging concept (two orbit surface coils (each focusing on one eye) additionally to the standard head coil) in 43 patients/45 eyes. Image analysis was performed by two neuroradiologists in consensus. Histopathology served as gold standard. Detection rate for choroidal invasion was higher for the new compared to that for the old imaging concept (sensitivity/specificity 87.5/94.6 % vs. 57.1/96.1 % for choroidal invasion and 100/97.5 % vs. 58.3/97.7 % for massive choroidal invasion, respectively). Sensitivity and specificity for the detection of postlaminar optic nerve infiltration, peribulbar fat, and scleral invasion were comparable in both imaging concepts; however positive predictive value was higher in the new imaging concept (new vs. old imaging concept: 60 vs. 31.6 % for postlaminar and deep postlaminar optic nerve infiltration, respectively, and 100 vs. 66.7 % for scleral invasion). The new imaging concept shows a trend towards improving the accuracy of detecting metastatic risk factors in children with retinoblastoma and is therefore recommended for pretherapeutic imaging and follow-up.

  8. Long-term solar activity and terrestrial connections. Part I: theory

    1998-05-01

    Full Text Available The research task described herein aims at the structuring of an analytical tool that traces the time course of geophysical phenomena, regional or global, and compares it to the course of long-term solar conditions, long-term meaning decades or a few centuries. The model is based on the premise that since in a last analysis the preponderance of atmospheric, hydrospheric, and, possibly, some aspects of geospheric phenomena are, or have been, powered by energy issuing from the sun – either now or in the past, the long-term behavior of such phenomena is ultimately "connected" to long-term changes occurring in the sun itself. Accordingly, the proposed research firstly derives and models a stable surrogate pattern for the long-term solar activity, secondly introduces a transfer-function algorithm for modeling the connection between the surrogate and terrestrial phenomena viewed as partners in the connection, and thirdly probes the connection outcome for episodic or unanticipated effects that may arise due to the fact that in the present context, the connection, should it exist, is very likely nonlinear. Part I of the study presents the theory of the concept, while Part II demonstrates the concept's pertinence to a number of terrestrial phenomena.Key words. Solar activity · Kolmogorov algorithm

  9. Nursing as concrete philosophy, Part I: Risjord on nursing knowledge.

    Theodoridis, Kyriakos

    2018-04-01

    This essay addresses the problem of the essentiality of nursing knowledge and what kind of theory, if any, is essential to nursing practice. The overarching aim of the essay was to argue for the thesis that nursing may be described as a kind of philosophical activity, and, consequently, that philosophy is the kind of "theory" that is essential to nursing practice and to the nursing discipline at large. The essay consists of two papers. The present paper, Part I, is a critical examination of Mark Risjord's discussion of the problem of the theory-practice gap in his Nursing Knowledge: Practice, Science, Philosophy, from 2010. According to Risjord, the cause of the theory-practice gap originates in an erroneous conception of science (logical positivism) which had a decisive influence upon the way nursing scholars appropriated theoretical frameworks for the nursing discipline. This philosophical influence is considered in effect to have generated the theory-practice gap. In order to bridge the gap, Risjord suggests, the nursing discipline needs to adopt a standpoint epistemology conjoined with a postpositivist conception of scientific theory. In this way, a legitimate brand of nursing science may be developed and the theory-practice gap overcome. I will argue that neither Risjord's diagnosis of the problem, nor his recommended cure, may succeed in rescuing the nursing discipline from the theory-practice gap. Rather, the real cause of the theory-practice gap, I will claim, derives from an erroneous conception of nursing (not of science), namely the conception of nursing as a kind of science (roughly speaking). On my view, to overcome the gap, the nursing discipline needs to make salient the inherently philosophical character of nursing. In the second paper (Part II), I will continue the discussion of nursing knowledge and delineate the thesis of nursing as a kind of concrete philosophy. © 2017 John Wiley & Sons Ltd.

    The aims of psychoanalysis are reviewed in terms of theories of mental function and structure. The theory of mental conflict remains the central theory of classical psychoanalysis but has been deepened and supplemented by newer theories. In particular the theory of projective identification has radically altered our view of mental structure and function and has allowed us to reformulate the aims of psychoanalysis in terms of the re-acquisition and re-integration of projected parts of the self. The central role of mourning in this process is discussed, and some of the obstacles to progress are reviewed. It is suggested that oedipal resentments may play a central role in the creation of impasse.

    Ontologies are knowledge structures that lend support to many health-information systems. A study is carried out to assess the quality of ontological concepts based on a measure of their complexity. The results show a relation between complexity of concepts and error rates of concepts. A measure of lateral complexity defined as the number of exhibited role types is used to distinguish between more complex and simpler concepts. Using a framework called an area taxonomy, a kind of abstraction network that summarizes the structural organization of an ontology, concepts are divided into two groups along these lines. Various concepts from each group are then subjected to a two-phase QA analysis to uncover and verify errors and inconsistencies in their modeling. A hierarchy of the National Cancer Institute thesaurus (NCIt) is used as our test-bed. A hypothesis pertaining to the expected error rates of the complex and simple concepts is tested. Our study was done on the NCIt's Biological Process hierarchy. Various errors, including missing roles, incorrect role targets, and incorrectly assigned roles, were discovered and verified in the two phases of our QA analysis. The overall findings confirmed our hypothesis by showing a statistically significant difference between the amounts of errors exhibited by more laterally complex concepts vis-à-vis simpler concepts. QA is an essential part of any ontology's maintenance regimen. In this paper, we reported on the results of a QA study targeting two groups of ontology concepts distinguished by their level of complexity, defined in terms of the number of exhibited role types. The study was carried out on a major component of an important ontology, the NCIt. The findings suggest that more complex concepts tend to have a higher error rate than simpler concepts. These findings can be utilized to guide ongoing efforts in ontology QA.

    Experiencing a major natural disaster is a stressful event that challenges survival and sense of self. Adolescents are undergoing rapid developmental change in self-concept, and their sense of self is particularly susceptible to such stressful events. Although many studies have investigated adolescent self-concept, few have examined self-concept in relation to experiencing a natural disaster. Following the Great Wenchuan Earthquake in Sichuan Province, China, in 2008, this study aimed to (a) describe disaster experiences; (b) describe social support, coping, and self-support; and (c) identify disaster experiences, social support, and coping factors associated with self-concept of adolescent survivors 3 months after the earthquake. This was a large-scale cross-sectional study. A total of 1,976 adolescents living where the earthquake caused the most severe damage took part. The Tennessee Self-Concept Scale; Coping Styles Scale; and Internality, Powerful Others, and Chance Scales were used to assess self-concept, coping strategy, and locus of control, respectively. Sociodemographic characteristics, earthquake experiences, and social support were also obtained by self-report. Three months after the disaster, adolescent self-concept was generally positive. Locus of control centered on powerful others was the strongest predictor of total self-concept. The negative coping strategy, "abreacting," was a positive predictor of negative self-concept (self-criticism). Close attention to adolescents who use negative coping strategies and who tend to lack a sense of control is needed after major disaster events. Studies that examine long-term relationships between earthquake and other major disaster experiences and self-concept of adolescent survivors are needed.

    2015-01-01

    The second part of this article series presents an evidence-based update of clinical protocols and procedures for cavity preparation and restoration selection for bonded inlays and onlays. More than ever, tissue conservation dictates preparation concepts, even though some minimal dimensions still have to be considered for all restorative materials. In cases of severe bruxism or tooth fragilization, CAD/CAM composite resins or pressed CAD/CAM lithium disilicate glass ceramics are often recommended, although this choice relies mainly on scarce in vitro research as there is still a lack of medium- to long-term clinical evidence. The decision about whether or not to cover a cusp can only be made after a multifactorial analysis, which includes cavity dimensions and the resulting tooth biomechanical status, as well as occlusal and esthetic factors. The clinical impact of the modern treatment concepts that were outlined in the previous article - Dual Bonding (DB)/Immediate Dentin Sealing (IDS), Cavity Design Optimization (CDO), and Cervical Margins Relocation (CMR) - are described in detail in this article and discussed in light of existing clinical and scientific evidence for simpler, more predictable, and more durable results. Despite the wide choice of restorative materials (composite resin or ceramic) and techniques (classical or CAD/CAM), the cavity for an indirect restoration should meet five objective criteria before the impression.

    The purpose of this study was to explore the differences in satisfaction with body image depending on whether the subject practices organized sport or not, as well as the gender of the children. In addition, the study aims to examine the role of body image and the practice of organized sport on the process of building the academic, social, emotional, family and physical dimensions of self-concept in childhood. To do so, a sample of 944 pupils was used. These children were attending primary school in different centers of the Autonomous Community of Extremadura (Spain) and were between 9 and 12 years of age. The main results of the study show that three out of every four children participating in this study were not satisfied with their figure and one out of every five was very dissatisfied. The satisfaction or dissatisfaction with the figure was similar in boys and girls, although it could be appreciated that the ideal body image is partly conditioned by gender stereotypes. The children most satisfied with their body image had a greater academic and physical self-concept. The children that practiced organized sports had a greater physical and emotional self-concept. The children most dissatisfied with their body image and practiced organized sports had a lower family self-concept. All these findings are discussed with reference to previous research literature.

    Exploring the concept of ethical competence in the context of healthcare is essential as it pertains to better quality of care. The concept still lacks a comprehensive definition covering the aspects of ethical expertise, ethical knowledge and action of a health professional. This article aims to report an analysis of the concept of ethical competence. A modified strategy suggested by Walker and Avant was used to analyse the concept. As a result, the concept of ethical competence can be defined in terms of character strength, ethical awareness, moral judgement skills and willingness to do good. Virtuous professional, experience of a professional, human communication, ethical knowledge and supporting surroundings in the organisation can be seen as prerequisites for ethical competence. Ethical competence results in the best possible solutions for the patient, reduced moral distress at work and development and democratisation of society. The results of the analysis establish a basis for an instrument to evaluate health professionals' ethical competence. It will guide educators, as well as managers in healthcare, to support the development of ethical conduct in healthcare. © The Author(s) 2015.

    In this book, the authors describe the findings derived from interaction and cooperation between scientific actors employing diverse practices. They reflect on distinct prototyping concepts and examine the transformation of development culture in their fusion to hybrid approaches and solutions. The products of tomorrow are going to be multifunctional, interactive systems – and already are to some degree today. Collaboration across multiple disciplines is the only way to grasp their complexity in design concepts. This underscores the importance of reconsidering the prototyping process for the development of these systems, particularly in transdisciplinary research teams. “Rethinking Prototyping – new hybrid concepts for prototyping” was a transdisciplinary project that took up this challenge. The aim of this programmatic rethinking was to come up with a general concept of prototyping by combining innovative prototyping concepts, which had been researched and developed in three sub-projects: “Hybrid P...

    2010-05-01

    Keywords: 3D-Metrology, Engineering Geodesy, Digital Image Processing Initialized in 2009, the Institute for Spatial Information and Surveying Technology i3mainz, Mainz University of Applied Sciences, forces research towards modular concepts for imaging total stations. On the one hand, this research is driven by the successful setup of high precision imaging motor theodolites in the near past, on the other hand it is pushed by the actual introduction of integrated imaging total stations to the positioning market by the manufacturers Topcon and Trimble. Modular concepts for imaging total stations are manufacturer independent to a large extent and consist of a particular combination of accessory hardware, software and algorithmic procedures. The hardware part consists mainly of an interchangeable eyepiece adapter offering opportunities for digital imaging and motorized focus control. An easy assembly and disassembly in the field is possible allowing the user to switch between the classical and the imaging use of a robotic total station. The software part primarily has to ensure hardware control, but several level of algorithmic support might be added and have to be distinguished. Algorithmic procedures allow to reach several levels of calibration concerning the geometry of the external digital camera and the total station. We deliver insight in our recent developments and quality characteristics. Both the modular and the integrated approach seem to have its individual strengths and weaknesses. Therefore we expect that both approaches might point at different target applications. Our aim is a better understanding of appropriate applications for robotic imaging total stations. First results are presented.

    To conduct a concept analysis of clinical practice contexts (work environments) that facilitate or militate against the uptake of research evidence by healthcare professionals in clinical practice. This will involve developing a clear definition of context by describing its features, domains and defining characteristics. The context where clinical care is delivered influences that care. While research shows that context is important to knowledge translation (implementation), we lack conceptual clarity on what is context, which contextual factors probably modify the effect of knowledge translation interventions (and hence should be considered when designing interventions) and which contextual factors themselves could be targeted as part of a knowledge translation intervention (context modification). Concept analysis. The Walker and Avant concept analysis method, comprised of eight systematic steps, will be used: (1) concept selection; (2) determination of aims; (3) identification of uses of context; (4) determination of defining attributes of context; (5) identification/construction of a model case of context; (6) identification/construction of additional cases of context; (7) identification/construction of antecedents and consequences of context; and (8) definition of empirical referents of context. This study is funded by the Canadian Institutes of Health Research (January 2014). This study will result in a much needed framework of context for knowledge translation, which identifies specific elements that, if assessed and used to tailor knowledge translation activities, will result in increased research use by nurses and other healthcare professionals in clinical practice, ultimately leading to better patient care. © 2014 John Wiley & Sons Ltd.

    Different alternatives are presented for a reactor aimed to produce radioisotopes with a low enrichment fuel element geometrically equal to those of low enrichment. Different alternatives are presented which essentially differ in the core's configuration, fuel management and 'meat' fuel material: U3O8, U3Si or U3Si2 in aluminium matrix. Fluxes at different irradiation positions and power full peak factors are described for each case. The main aspects to be taken into account for cobalt irradiation and the method to be followed to measure the reactor as a function of a required production are presented. (Author) [es

    The yaw system is the subsystem on a wind turbine which ensures that the rotor plane of the turbine always is facing the wind direction. Studies from [1] show that a soft yaw system may be utilized to dampen the loads in the wind turbine structure. The soft yaw system operates much like...... investigation. Loads and yaw demands are based on the IEC 61400-1 standard for wind turbine design, and the loads for this examination are extrapolated from the HAWC2 aeroelastic design code. The concepts are based on a 5 MW off-shore turbine....... a suspension system on a car, leading the loads away from the turbine structure. However, to realize a soft hydraulic yaw system a new design concept must be found. As a part of the development of the new concept a preliminary concept evaluation has been conducted, evaluating seven different hydraulic yaw...

    Full Text Available By following the example proposed by Corrêa (2011 in the investigation of texts produced by undergraduate and pre-undergraduate students in two different assessment, this work aims to approach “hidden” aspects in the teaching of writing at the university (Street, 2009, to reflections produced in the language field, in particular the ones referred as “socially assumed”, proposed by Voloshinov/Bakhtin (s/d: 1926. It is particularly important to investigate the conception of text in digital context, by means of the study of updated semiotic resources in the production of undergraduate students using a computer with internet access in the process of semi-present Distance Learning (DL. The collected material comprises 29 (twenty nine texts which were produced by students of the semi-present Pedagogy Course from Univesp (Universidade Virtual do Estado de São Paulo – Virtual University from the state of São Paulo, who were studying “Education and Language”, in 2010. This qualitative analysis aims to show that regarding the institution there is a prevalence of structural and procedural aspects for the accomplishment of the proposed activity and, regarding the undergraduate student it is noticed that the production is characterized by a traditional conception of text, mainly recognized by written verbal text, although the proposal prioritized the relation between verbal and non verbal language. Regarding discursive-linguistic studies, it is important to reflect about a text conception that privileges the integration of multiple semiosis by taking into account the socio-historical interlocution character established within utterances of others.

  15. A generative model for scientific concept hierarchies.

    2018-01-01

    In many scientific disciplines, each new 'product' of research (method, finding, artifact, etc.) is often built upon previous findings-leading to extension and branching of scientific concepts over time. We aim to understand the evolution of scientific concepts by placing them in phylogenetic hierarchies where scientific keyphrases from a large, longitudinal academic corpora are used as a proxy of scientific concepts. These hierarchies exhibit various important properties, including power-law degree distribution, power-law component size distribution, existence of a giant component and less probability of extending an older concept. We present a generative model based on preferential attachment to simulate the graphical and temporal properties of these hierarchies which helps us understand the underlying process behind scientific concept evolution and may be useful in simulating and predicting scientific evolution.

  17. Concept of innovative water reactor for flexible fuel cycle (FLWR)

    Iwamura, T.; Uchikawa, S.; Okubo, T.; Kugo, T.; Akie, H.; Nakatsuka, T.

    2005-01-01

    In order to ensure sustainable energy supply in the future based on the matured Light Water Reactor (LWR) and coming LWR-Mixed Oxide (MOX) technologies, a concept of Innovative Water Reactor for Flexible Fuel Cycle (FLWR) has been investigated in Japan Atomic Energy Research Institute (JAERI). The concept consists of two parts in the chronological sequence. The first part realizes a high conversion type core concept, which is basically intended to keep the smooth technical continuity from current LWR and coming LWR-MOX technologies without significant gaps in technical point of view. The second part represents the Reduced-Moderation Water Reactor (RMWR) core concept, which realizes a high conversion ratio over 1.0 being useful for the long-term sustainable energy supply through plutonium multiple recycling based on the well-experienced LWR technologies. The key point is that the two core concepts utilize the compatible and the same size fuel assemblies, and hence, the former concept can proceed to the latter in the same reactor system, based flexibly on the fuel cycle circumstances during the reactor operation period around 60 years. At present, since the fuel cycle for the plutonium multiple recycling with MOX fuel reprocessing has not been realized yet, reprocessed plutonium from the LWR spent fuel is to be utilized in LWR-MOX. After this stage, the first part of FLWR, i.e. the high conversion type, can be introduced as a replacement of LWR or LWR-MOX. Since the plutonium inventory of FLWR is much larger, the number of the reactor with MOX fuel will be significantly reduced compared to the LWR-MOX utilization. The size of the fuel assembly for the first part is the same as in the RMWR concept, i.e. the hexagonal fuel assembly with the inner face-to-face distance of about 200 mm. Fuel rods are arranged in the triangular lattice with a relatively wide gap size around 3 mm between rods, and the effective MOX length is less than 1.5 m without using the blanket. When

    2013-12-01

    Full Text Available This article investigates the relationship between landscape and heritage and brings a brief critical analysis of the United Nations Educational, Scientific and Cultural Organization (UNESCO practice since the institutionalization of cultural landscape category, created on the World Heritage list in 1992, until 2012. The text is structured in three parts. The first presents a brief historical approach about the concept of Western landscape. The second presents recent formulations on the cultural landscape based on international conventions, such as the Council of Europe (1995 and the Landscape European Convention (2000. The third part focuses on the analysis of the World Heritage Committee work, comprising the main characteristics and values of cultural landscapes listed. Finally, the study reveals how the employment of this new concept is still reflecting old conceptions of landscape and preservation, although points towards perspective in the heritage policies, especially as regards the own expansion of the heritage concept and the approximation between the natural and cultural, material and immaterial dimensions.

    The Earth, Wind and Fire concept transforms a building into a 'climate machine' which is powered by the natural forces and energy of the sun, wind, the mass of the earth and gravity. This concept consists of a Climate Cascade, a solar chimney and a Ventec roof, which have been tested in physical mock-ups. Simulation models have been validated on the basis of real measurements. This work has resulted in the creation of reliable tools for design practice [Dutch] Het Earth, Wind en Fire-concept voor natuurlijke airconditioning biedt meer zekerheid voor het realiseren van energieneutrale kantoorgebouwen dan mogelijk zou zijn door verbetering van bestaande technieken. Het concept maakt gebruik van de omgevingsenergie van aardmassa, wind en zon. Enerzijds wordt deze energie passief gebruikt voor het realiseren van een natuurlijke airconditioning, waarbij de gewenste luchtstromingen tot stand komen onder invloed van thermisch gedreven drukverschillen. Anderzijds worden zon en wind benut voor actieve energieopwekking, waardoor een gebouw in principe energieneutraal kan worden. Een dergelijk gebouw kan worden beschouwd als 'klimaatmachine', geactiveerd door zwaartekracht, wind en zon.

  2. Basic concepts from magnetic resonance imaging

    The use of magnetic resonance imaging (MRI) has grown exponentially, due in part to excellent anatomic and pathologic detail provided by the modality, as recent technological advances that have led to more rapid acquisition times. Radiology residents in different parts of the world now receive training in MR images from their first year of residence, included the pulse sequences training spin-echo, gradient-echo, inversion-recovery, echo-planar image and MR angiographic sequences, commonly used in medical imaging. However, to optimize the use of this type of study, it has been necessary to understand the basic concepts of physics, included the concepts of recovery T1, degradation T2* and T2, repetition time, echo time, and the effects of chemical shift. Additionally, it has been important to understand the contrast weighting for better representation of specific tissues and thus perform an appropriate differential diagnosis of various pathological processes.

    1996-04-01

    In many ways, the Advanced Industrial Materials (AIM) Program underwent a major transformation in Fiscal Year 1995 and these changes have continued to the present. When the Program was established in 1990 as the Advanced Industrial Concepts (AIC) Materials Program, the mission was to conduct applied research and development to bring materials and processing technologies from the knowledge derived from basic research to the maturity required for the end use sectors for commercialization. In 1995, the Office of Industrial Technologies (OIT) made radical changes in structure and procedures. All technology development was directed toward the seven ``Vision Industries`` that use about 80% of industrial energy and generated about 90% of industrial wastes. The mission of AIM has, therefore, changed to ``Support development and commercialization of new or improved materials to improve productivity, product quality, and energy efficiency in the major process industries.`` Though AIM remains essentially a National Laboratory Program, it is essential that each project have industrial partners, including suppliers to, and customers of, the seven industries. Now, well into FY 1996, the transition is nearly complete and the AIM Program remains reasonably healthy and productive, thanks to the superb investigators and Laboratory Program Managers. This Annual Report for FY 1995 contains the technical details of some very remarkable work by the best materials scientists and engineers in the world. Areas covered here are: advanced metals and composites; advanced ceramics and composites; polymers and biobased materials; and new materials and processes.

  5. Feasibility of tailoring of press formed thermoplastic composite parts

    Sinke, J.

    2018-05-01

    The Tailor Made Blank concept is widely accepted in the production of sheet metal parts. By joining, adding and subtracting materials, and sometimes even applying different alloys, parts can be produced more efficiently by cost and/or weight, and new design options have been discovered. This paper is about the manufacture of press formed parts of Fibre Reinforced Thermoplastics and the evaluation whether the Tailoring concept, though adapted to the material behavior of FRTP, can be applied to these composites as well. From research, the first results and ideas are presented. One of the ideas is the multistep forming process, creating parts with thickness variations and combinations of fibre orientations that are usually not feasible using common press forming strategies. Another idea is the blending of different prepreg materials in one component. This might be useful in case of specific details, like for areas of mechanical fastening or to avoid carbon/metal contact, otherwise resulting in severe corrosion. In a brief overview, future perspectives of the potential of the Tailoring concept are presented.

    International Nuclear Information System (INIS)

    Matzke, H.

    2000-01-01

    Part I of this contribution on innovative nuclear fuels gives a summary of current developments and problems of today's fuels, i.e. enriched UO 2 and UO 2 with a few % of PUO 2 (MOX fuel) or Gd 2 O 3 (as burnable neutron poison). The problems and property changes caused by high burnups (e.g. degradation of the thermal conductivity, polygonization or formation of the rim-structure) are discussed. Subsequently, the concepts for new fuels to burn excess Pu and to achieve an effective transmutation of the minor actinides Np, Am and Cm are treated. The criteria for the choice of suitable fuels and different fuel types (high Pu-content fuels, nitrides, U-free fuels, inert matrix supported fuels, cercers, cermets, etc.) are discussed. Part II of this contribution on innovative nuclear fuels deals with the properties of relevance of the different materials suggested to be used in innovative fuels which range from pure actinide fuel such as PuN and AmO 2 to spinel MgAl 2 O 4 and zircon ZrSiO 4 for inert matrix-based fuels, etc. The available knowledge on materials research aspects is summarized with emphasis on the physics of radiation damage. It is shown that significant gaps in the present knowledge exist, e.g. for the minor actinide compounds, and suggestions are made to fill these gaps in order to achieve a sufficient data base to design and operate suitable innovative fuels in a near future.

  13. Comfort measures: a concept analysis.

    Science.gov (United States)

    Oliveira, Irene

    2013-01-01

    Reference to the concept of comfort measures is growing in the nursing and medical literature; however, the concept of comfort measures is rarely defined. For the comfort work of nurses to be recognized, nurses must be able to identify and delineate the key attributes of comfort measures. A concept analysis using Rodgers' evolutionary method (2000) was undertaken with the goal of identifying the core attributes of comfort measures and thereby clarifying this concept. Health care literature was accessed from the CINAHL and PubMed databases. No restrictions were placed on publication dates. Four main themes of attributes for comfort measures were identified during the analysis. Comfort measures involve an active, strategic process including elements of "stepping in" and "stepping back," are both simple and complex, move from a physical to a holistic perspective and are a part of supportive care. The antecedents to comfort measures are comfort needs and the most common consequence of comfort measures is enhanced comfort. Although the concept of comfort measures is often associated with end-of-life care, this analysis suggests that comfort measures are appropriate for nursing care in all settings and should be increasingly considered in the clinical management of patients who are living with multiple, chronic comorbidities.

  14. Long-term solar activity and terrestrial connections. Part I: theory

    Directory of Open Access Journals (Sweden)

    N. D. Diamantides

    Full Text Available The research task described herein aims at the structuring of an analytical tool that traces the time course of geophysical phenomena, regional or global, and compares it to the course of long-term solar conditions, long-term meaning decades or a few centuries. The model is based on the premise that since in a last analysis the preponderance of atmospheric, hydrospheric, and, possibly, some aspects of geospheric phenomena are, or have been, powered by energy issuing from the sun – either now or in the past, the long-term behavior of such phenomena is ultimately "connected" to long-term changes occurring in the sun itself. Accordingly, the proposed research firstly derives and models a stable surrogate pattern for the long-term solar activity, secondly introduces a transfer-function algorithm for modeling the connection between the surrogate and terrestrial phenomena viewed as partners in the connection, and thirdly probes the connection outcome for episodic or unanticipated effects that may arise due to the fact that in the present context, the connection, should it exist, is very likely nonlinear. Part I of the study presents the theory of the concept, while Part II demonstrates the concept's pertinence to a number of terrestrial phenomena.

  15. Narrative and epistemology: Georges Canguilhem's concept of scientific ideology.

    Science.gov (United States)

    Chimisso, Cristina

    2015-12-01

    In the late 1960s, Georges Canguilhem introduced the concept of 'scientific ideology'. This concept had not played any role in his previous work, so why introduce it at all? This is the central question of my paper. Although it may seem a rather modest question, its answer in fact uncovers hidden tensions in the tradition of historical epistemology, in particular between its normative and descriptive aspects. The term ideology suggests the influence of Althusser's and Foucault's philosophies. However, I show the differences between Canguilhem's concept of scientific ideology and Althusser's and Foucault's respective concepts of ideology. I argue that Canguilhem was in fact attempting to solve long-standing problems in the tradition of historical epistemology, rather than following the lead of his younger colleagues. I argue that Canguilhem's 'refurbishment without rejection' of Bachelard's epistemology, which the concept of scientific ideology was aimed to implement, was necessary to justify the historical narratives that Canguilhem had constructed in his own work as a historian of concepts. A strict acceptance of Bachelard's epistemology would have made it impossible to justify them. Canguilhem's concept of scientific ideology therefore served as a theoretical justification of his practice as a historian. I maintain that the concept of scientific ideology was needed to reconcile Bachelard's normative epistemology with Canguilhem's view of the history of science and its aims, which differed from Bachelard's more than it is generally acknowledged.

  17. Calling to Nursing: Concept Analysis.

    Science.gov (United States)

    Emerson, Christie

    The aims of this article are (a) to analyze the concept of a calling as it relates nursing and (b) to develop a definition of calling to nursing with the detail and clarity needed to guide reliable and valid research. The classic steps described by Walker and Avant are used for the analysis. Literature from several disciplines is reviewed including vocational psychology, Christian career counseling, sociology, organizational management, and nursing. The analysis provides an operational definition of a calling to nursing and establishes 3 defining attributes of the concept: (a) a passionate intrinsic motivation or desire (perhaps with a religious component), (b) an aspiration to engage in nursing practice, as a means of fulfilling one's purpose in life, and (c) the desire to help others as one's purpose in life. Antecedents to the concept are personal introspection and cognitive awareness. Positive consequences to the concept are improved work meaningfulness, work engagement, career commitment, personal well-being, and satisfaction. Negative consequences of having a calling might include willingness to sacrifice well-being for work and problems with work-life balance. Following the concept analysis, philosophical assumptions, contextual factors, interdisciplinary work, research opportunities, and practice implications are discussed.

  18. Reforming Science Education: Part II. Utilizing Kieran Egan's Educational Metatheory

    Science.gov (United States)

    Schulz, Roland M.

    2009-04-01

    This paper is the second of two parts and continues the conversation which had called for a shift in the conceptual focus of science education towards philosophy of education, with the requirement to develop a discipline-specific “philosophy” of science education. In Part I, conflicting conceptions of science literacy were identified with disparate “visions” tied to competing research programs as well as school-based curricular paradigms. The impasse in the goals of science education and thereto, the contending views of science literacy, were themselves associated with three underlying fundamental aims of education (knowledge-itself; personal development; socialization) which, it was argued, usually undercut the potential of each other. During periods of “crisis-talk” and throughout science educational history these three aims have repeatedly attempted to assert themselves. The inability of science education research to affect long-term change in classrooms was correlated not only to the failure to reach a consensus on the aims (due to competing programs and to the educational ideologies of their social groups), but especially to the failure of developing true educational theories (largely neglected since Hirst). Such theories, especially metatheories, could serve to reinforce science education’s growing sense of academic autonomy and independence from socio-economic demands. In Part II, I offer as a suggestion Egan’s cultural-linguistic theory as a metatheory to help resolve the impasse. I hope to make reformers familiar with his important ideas in general, and more specifically, to show how they can complement HPS rationales and reinforce the work of those researchers who have emphasized the value of narrative in learning science.

  19. [Education in our time: competency or aptitude? The case for medicine. Part II].

    Science.gov (United States)

    Viniegra-Velázquez, Leonardo

    Part II is focused on participatory education (PE), a distinctive way to understand and practice education in contrast to passive education. The core of PE is to develop everyone's own cognitive potentialities frequently mutilated, neglected or ignored. Epistemological and experiential basis of PE are defined: the concept of incisive and creative criticism, the idea of knowledge as each person's own construct and life experience as the main focus of reflection and cognition. The PE aims towards individuals with unprecedented cognitive and creative faculties, capable of approaching a more inclusive and hospitable world. The last part criticizes the fact that medical education has remained among the passive education paradigm. The key role of cognitive aptitudes, both methodological and practical (clinical aptitude), in the progress of medical education and practice is emphasized. As a conclusion, the knowhow of education is discussed, aiming towards a better world away from human and planetary degradation. Copyright © 2017 Hospital Infantil de México Federico Gómez.

    International Nuclear Information System (INIS)

    Mittendorfer, J.

    2006-01-01

    This paper provides a systematic survey of systems and concepts used in the industrial irradiation of polymers. It consists basically of three parts: in the first part, different types of applications like wires and cables, pipes and engineering plastics are discussed and the associated irradiation systems analyzed and highlighted according their basics modules. These are identified as the radiation source, the product handling system, process control and facility/shielding layout. In the second part, the irradiation process design is reviewed in detail. The discussion starts with the requirement analysis, e.g. the desired polymer parameters and effects, continues with a process development roadmap and concludes with process verification and validation. Special attention is drawn to process control, which plays an important role in industrial irradiation technology. The use of mathematical modeling to facilitate and support process and system design is discussed as well and several examples are given which demonstrate their capabilities. In the third part, the design of a electron beam facility for the irradiation of small plastic parts for the automotive industry is worked out in detail. Besides system and product handling considerations, throughput and economical estimates are provided. The paper concludes with a summary of the design and concept bullets which proved to be important in history and can facilitate new developments which will enhance the potential of industrial polymer irradiation

    Full Text Available The paper aims to achieve a definition of the concept of sustainability and of sustainable system from a logical perspective. In this respect, it introduces and defines (through the sufficiency predicates the concept of logically vivid system and, on this basis, are discussed a logical concept of sustainability, respectively of a sustainable system in general are discussed and built up. Sustainability is considered in light of identity preservation of the systems, as a static anchor, on one hand, and of the concept of automatic stabilizers as a dynamic anchor on the other side. Finally, the two sufficiency conditions for a logically vivid system be sustainable are identified: the presence of hyper-cycles, respectively the absence of positive feed-back.

    2007-01-01

    The spatial, energy, and time resolutions of 10 cm long polished YAP:Ce and LYSO:Ce crystals have been measured. The work is part of the novel HPD-PET concept, based on a full three-dimensional, free of parallax errors, reconstruction of the γ-ray interaction point in 10–15 cm long scintillators. The effective light attenuation length, a key parameter of the HPD-PET concept, and the resolutions have been measured for various wrappings and coatings of the crystal lateral surfaces. Even if the final HPD-PET prototype could use scintillators and/or wrappings different from those tested, the results here presented prove the feasibility of the concept and provide hints on its potential capabilities.

  6. Advanced composite structural concepts and material technologies for primary aircraft structures

    Science.gov (United States)

    Jackson, Anthony

    1991-01-01

    Structural weight savings using advanced composites have been demonstrated for many years. Most military aircraft today use these materials extensively and Europe has taken the lead in their use in commercial aircraft primary structures. A major inhibiter to the use of advanced composites in the United States is cost. Material costs are high and will remain high relative to aluminum. The key therefore lies in the significant reduction in fabrication and assembly costs. The largest cost in most structures today is assembly. As part of the NASA Advanced Composite Technology Program, Lockheed Aeronautical Systems Company has a contract to explore and develop advanced structural and manufacturing concepts using advanced composites for transport aircraft. Wing and fuselage concepts and related trade studies are discussed. These concepts are intended to lower cost and weight through the use of innovative material forms, processes, structural configurations and minimization of parts. The approach to the trade studies and the downselect to the primary wing and fuselage concepts is detailed. The expectations for the development of these concepts is reviewed.

  7. Suicide Lethality: A Concept Analysis.

    Science.gov (United States)

    DeBastiani, Summer; De Santis, Joseph P

    2018-02-01

    Suicide is a significant health problem internationally. Those who complete suicide may have different behaviors and risk factors than those who attempt a non-fatal suicide. The purpose of this article is to analyze the concept of suicide lethality and propose a clear definition of the concept through the identification of antecedents, attributes, and consequences. A literature search for articles published in the English language between 1970 and 2016 was conducted using MEDLINE, the Cochrane Library, Pubmed, Psychlit, Ovid, PsycINFO, and Proquest. The bibliographies of all included studies were also reviewed to identify additional relevant citations. A concept analysis was conducted on the literature findings using six stages of Walker and Avant's method. The concept analysis differentiated between suicide, lethality, suicidal behavior, and suicide lethality. Presence of a suicide plan or a written suicide note was not found to be associated with the majority of completed suicides included in the definition of suicide lethality. There are a few scales that measure the lethality of a suicide attempt, but none that attempt to measure the concept of suicide lethality as described in this analysis. Clarifying the concept of suicide lethality encourages awareness of the possibility of different suicidal behaviors associated with different suicide outcomes and will inform the development of future nursing interventions. A clearer definition of the concept of suicide lethality will guide clinical practice, research, and policy development aimed at suicide prevention.

    1997-04-01

    The Advanced Industrial Materials (AIM) Program underwent a major transformation in Fiscal Year 1995 and these changes have continued to the present. When the Program was established in 1990 as the Advanced Industrial Concepts (AIC) Materials Program, the mission was to conduct applied research and development to bring materials and processing technologies from the knowledge derived from basic research to the maturity required for the end use sectors for commercialization. In 1995, the Office of Industrial Technologies (OIT) made radical changes in structure and procedures. All technology development was directed toward the seven `Vision Industries` that use about 80% of industrial energy and generated about 90% of industrial wastes. These are: aluminium; chemical; forest products; glass; metal casting; refineries; and steel. OIT is working with these industries, through appropriate organizations, to develop Visions of the desired condition of each industry some 20 or 25 years in the future and then to prepare Road Maps and Implementation Plans to enable them to reach their goals. The mission of AIM has, therefore, changed to `Support development and commercialization of new or improved materials to improve productivity, product quality, and energy efficiency in the major process industries.` Though AIM remains essentially a National Laboratory Program, it is necessary that each project have industrial partners, including suppliers to, and customers of, the seven industries. Now, well into FY 1996, the transition is nearly complete and the AIM Program remains healthy and productive, thanks to the superb investigators and Laboratory Program Managers. Separate abstracts have been indexed into the energy database for articles from this report.

    International Nuclear Information System (INIS)

    Wright, T. de

    2007-01-01

    This paper seeks to analyse the incentive concept, initially adopted in the C.N.S. (convention on nuclear safety) and later developed in the Joint Convention, as the innovation credited with encouraging both participation in , and compliance with, the nuclear safety conventions. It then seeks to examine the possibilities for the introduction of that concept into other sectors of international law. In the first part of the paper, the essential features of the concept and the mechanisms used in the conventions to bring it into effect will be discussed. the second part of the paper will focus on the different aspects of the conventions which have been described as integral to the concept. The third part of the paper will identify certain apprehensions regarding the effectiveness of such 'soft' treaty provisions and explain why the ' incentive' concept may be particularly well suited to certain specific situations. The final part of the paper will address the potential application of the concept and related treaty provisions to other fields of law, particularly to international environmental law. in addition, some suggestions will be made as to how provisions implementing the incentive concept into a treaty may be slightly modified to increase their effectiveness.

    Mongkolwat, Pattanasak; Kleper, Vladimir; Talbot, Skip; Rubin, Daniel

    2014-12-01

    Knowledge contained within in vivo imaging annotated by human experts or computer programs is typically stored as unstructured text and separated from other associated information. The National Cancer Informatics Program (NCIP) Annotation and Image Markup (AIM) Foundation information model is an evolution of the National Institute of Health's (NIH) National Cancer Institute's (NCI) Cancer Bioinformatics Grid (caBIG®) AIM model. The model applies to various image types created by various techniques and disciplines. It has evolved in response to the feedback and changing demands from the imaging community at NCI. The foundation model serves as a base for other imaging disciplines that want to extend the type of information the model collects. The model captures physical entities and their characteristics, imaging observation entities and their characteristics, markups (two- and three-dimensional), AIM statements, calculations, image source, inferences, annotation role, task context or workflow, audit trail, AIM creator details, equipment used to create AIM instances, subject demographics, and adjudication observations. An AIM instance can be stored as a Digital Imaging and Communications in Medicine (DICOM) structured reporting (SR) object or Extensible Markup Language (XML) document for further processing and analysis. An AIM instance consists of one or more annotations and associated markups of a single finding along with other ancillary information in the AIM model. An annotation describes information about the meaning of pixel data in an image. A markup is a graphical drawing placed on the image that depicts a region of interest. This paper describes fundamental AIM concepts and how to use and extend AIM for various imaging disciplines.

  14. Concept Analysis: Alzheimer's Caregiver Stress.

    Science.gov (United States)

    Llanque, Sarah; Savage, Lynette; Rosenburg, Neal; Caserta, Michael

    2016-01-01

    The aim of this article was to analyze the concept of caregiver stress in the context of caring for a person with Alzheimer's disease and related dementias. Currently, there are more than 15 million unpaid caregivers for persons suffering from Alzheimer's disease and related dementias. This unpaid care can be stressful for caregivers due to the chronic nature of the disease process, as well as other factors. The paper incorporates the modified method of Wilson's concept analysis procedure to analyze the concept of caregiver stress. A review of the literature was undertaken using the Cumulative Index to Nursing and Allied Health Literature, Google Scholar, and PubMed. A theoretical definition of caregiver stress is provided, and the defining attributes, related concepts, antecedents, and consequences of caregiver stress are proposed, and case studies are presented. The analysis demonstrates that caregiver stress is the unequal exchange of assistance among people who stand in close relationship to one another, which results in emotional and physical stress on the caregiver. Implications for future nursing research and practice conclude the paper. © 2014 Wiley Periodicals, Inc.

    Breiter, R.; Ihle, T.; Rode, W.; Wendler, J.; Rühlich, I.; Haiml, M.; Ziegler, J.

    2008-04-01

    In all recent missions our forces are faced with various types of asymmetric threads like snipers, IEDs, RPGs or MANPADS. 2 nd and 3 rd Gen IR technology is a backbone of modern force protection by providing situational awareness and accurate target engagement at day/night. 3 rd Gen sensors are developed for thread warning capabilities by use of spectral or spatial information. The progress on a dual-color IR module is discussed in a separate paper [1]. A 1024x256 SWIR array with flexure bearing compressor and pulse tube cold finger provides > 50,000h lifetime for space or airborne hyperspectral imaging in pushbroom geometry with 256 spectral channels for improved change detection and remote sensing of IEDs or chemical agents. Similar concepts are pursued in the LWIR with either spectroscopic imaging or a system of LWIR FPA combined with a cooled tunable Laser to do spectroscopy with stimulated absorption of specific wavelengths. AIM introduced the RangIR sight to match the requirements of sniper teams, AGLs and weapon stations, extending the outstanding optronic performance of the fielded HuntIR with position data of a target by a laser range finder (LRF), a 3 axis digital magnetic compass (DMC) and a ballistic computer for accurate engagement of remote targets. A version with flexure bearing cooler with >30,000h life time is being developed for continuous operation in e.g. gunfire detection systems. This paper gives an overview of AIM's technologies for enhanced force protection.

    Full Text Available The aim of this article is twofold. On the one hand, I will outline the diverse usages that the concept of history has taken on throughout Western history. These different usages may be grouped together in three semantic fields (history as a way of knowing, as a way of being and as a way of doing, which correspond to three ways of understanding the Philosophy of History: as Epistemology of History, as Ontology of historicity and as ethical-political Critique of the present. On the other hand, I will show that these three concepts of history (and, accordingly, the three ways of understanding the Philosophy of History refer mutually to each other and, thus, are inseparable from each other.

    Scheydt, Stefan; Müller Staub, Maria; Frauenfelder, Fritz; Nielsen, Gunnar H; Behrens, Johann; Needham, Ian

    2017-04-01

    In the context of mental disorders sensory overload is a widely described phenomenon used in conjunction with psychiatric interventions such as removal from stimuli. However, the theoretical foundation of sensory overload as addressed in the literature can be described as insufficient and fragmentary. To date, the concept of sensory overload has not yet been sufficiently specified or analyzed. The aim of the study was to analyze the concept of sensory overload in mental health care. A literature search was undertaken using specific electronic databases, specific journals and websites, hand searches, specific library catalogues, and electronic publishing databases. Walker and Avant's method of concept analysis was used to analyze the sources included in the analysis. All aspects of the method of Walker and Avant were covered in this concept analysis. The conceptual understanding has become more focused, the defining attributes, influencing factors and consequences are described and empirical referents identified. The concept analysis is a first step in the development of a middle-range descriptive theory of sensory overload based on social scientific and stress-theoretical approaches. This specification may serve as a fundament for further research, for the development of a nursing diagnosis or for guidelines. © 2017 Australian College of Mental Health Nurses Inc.

    Full Text Available The aim of the study was to identify initial meanings of the concept of the gene among 50 students from the career training of teachers of biology at the University Pedagogical Experimental Libertador (UPEL, Pedagogical Institute of Caracas, who enrolled in Cell Biology (BC and General Genetics (GG, as well as those built from a didactic intervention that formed part of Participatory Action Research (PAR. The work is based on the Theory of Meaningful Learning of Ausubel, on the principles of critical meaningful learning facilitators of Moreira, and on elements of the educational act of Novak. To investigate the evolution of meaning of this concept were used: questionnaires, interviews, maps and graphic representations of concepts developed by students. The data analysis provides a differentiated evolution of the meaning of the gene in the students, which corresponds to the didactic intervention and teachers, actions in both courses. It shows the importance of organizing the teaching in a potentially meaningful way to reflect on the content and learning, so that abstract concepts such as gene, must be presented with a critical and reflexive epistemology.

    Weathers, Elizabeth; McCarthy, Geraldine; Coffey, Alice

    2016-04-01

    The aim of this article is to clarify the concept of spirituality for future nursing research. Previous concept analyses of spirituality have mostly reviewed the conceptual literature with little consideration of the empirical literature. The literature reviewed in prior concept analyses extends from 1972 to 2005, with no analysis conducted in the past 9 years. Rodgers' evolutionary framework was used to review both the theoretical and empirical literature pertaining to spirituality. Evolutionary concept analysis is a formal method of philosophical inquiry, in which papers are analyzed to identify attributes, antecedents, and consequences of the concept. Empirical and conceptual literature. Three defining attributes of spirituality were identified: connectedness, transcendence, and meaning in life. A conceptual definition of spirituality was proposed based on the findings. Also, four antecedents and five primary consequences of spirituality were identified. Spirituality is a complex concept. This concept analysis adds some clarification by proposing a definition of spirituality that is underpinned by both conceptual and empirical research. Furthermore, exemplars of spirituality, based on prior qualitative research, are presented to support the findings. Hence, the findings of this analysis could guide future nursing research on spirituality. © 2015 Wiley Periodicals, Inc.

    2013-06-01

    Full Text Available Farm animals are reared for production to meet up the demand for animal protein in human. Various modern medicines are extensively used for production as well as treatment and prevention of diseases of animals, which can ultimately reach us through food chain. Herbs are now considered as an important source of alternative medicines. The Ayurvedic medicines prepared by manufacturers contain processed plant parts and added with preservative and other chemicals in many cases. The present way of research on herbal medicine follows the path of identification of active principles from the extracts of preserved parts of medicinal plants after testing of their efficacy in laboratory. This concept of research have the limitation of loss of many aromatic and other phytochemicals present in the living plant, which may have very important role when used together. Animals maintained in modern farm may be given relief from modern medicines in minor and moderate ailments, cure of problems related with their production with the validated fresh plant medicine available from the plants cultivated adjacent to the farm area. Consulting the reports of ethno-botanical study, a preliminary list of medicinal plant is prepared which are having antipyretic, analgesic, wound healing, immunostimulant, hepato-protective, fertility enhancing, pregnancy assisting, lactation assisting, anthelmintic, astringent, expectorant, purgative and anti-flatulent, nutriceutical, antiseptic, anti-dermatitis, anti-dysenteric and anti-enteric, hematenic, stomachic, diuretic and kidney stone removing effects and insecticidal or insect repelling effects. This list may be enriched further and plants may be selected for a farm from these groups according to the agro-climatic condition of the area, disease prevalence, problems encountered during farming practice and other requirements of the farm. Validation of reported effects of the plants is to be performed in fresh condition, so that parts

    Since work ability is manifested in working life and ``bought'' by employers, employers perceptions of the concept are important to understand. Studies have shown that people with health problems want to take part in the labour market, but experience difficulties in gaining access. Additionally, studies have demonstrated the doubt felt by employers when they consider hiring a person with a disability. The aim was to identify and characterise employers' conceptions of work ability. The study design was qualitative with a phenomenographic approach. Six male and six female employers from various workplaces and geographical areas in Sweden were interviewed. Three domains were identified: employees' contributions to work ability, employers' contributions to work ability and circumstances with limited work ability. Work ability was regarded as a tool in production and its output, production, was the main issue. The employees' commitment and interest could bridge other shortcomings. The employers highlighted their own contributions in shaping work ability in order to fit with work circumstances. Health problems were not the only limiting issues; other circumstances, such as individual characteristics and contextual factors, could limit work ability too. Knowing the importance of commitment and interest is valuable in work rehabilitation.

    To demonstrate that antiquity's concepts of shame and guilt developed in their meaning over the centuries and can still have practical applicability in psychological therapies these days. To review shame and guilt in philosophy, history, ethics and psychiatry contexts. Within limitations, a narrative is presented, starting with Oedipus in antiquity, visiting several important philosophical theories and ending in the present time with, for example, Dan Hughes' PACE model for therapy. The first part expands on selected ideas presented in Melvyn Bragg's 2007 BBC radio programme entitled 'Guilt'; the second part adds selected therapeutic models where concepts of shame and guilt play a role. Shame and guilt are archaic but quintessential concepts that already occupied thinkers in antiquity. Shame and guilt are concepts that preoccupied science and art over the millennia and continue as useful concepts to the present day. Moreover, shame and guilt, as concepts, continue to play a salient role in recent and contemporary psychiatry. © The Royal Australian and New Zealand College of Psychiatrists 2015.

  19. Lay Worker Health Literacy: A Concept Analysis and Operational Definition.

    Cadman, Kathleen Paco

    2017-10-01

    The concept of lay worker health literacy is created by concurrently analyzing and synthesizing two intersecting concepts, lay workers and health literacy. Articulation of this unique intersection is the result of implementing a simplified Wilson's Concept Analysis Procedure. This process incorporates the following components: a) selecting a concept, b) determining the aims/purposes of analysis, c) identifying all uses of the concept, d) determining defining attributes, e) identifying a model case, f) identifying borderline, related, contrary, and illegitimate cases, g) identifying antecedents and consequences, and h) defining empirical referents. Furthermore, as current literature provides no operational definition for lay worker health literacy, one is created to contribute cohesion to the concept. © 2017 Wiley Periodicals, Inc.

    Full Text Available Background and aims. Different factors affect children’s behavior during dental treatment, including psychological and behavioral characteristics. The aim of this study was to evaluate the correlation of self-concept on child’s anxiety and be-havior during dental treatment in 4 to 6-year-old children. Materials and methods. A total of 235 preschoolers aged 4 to 6 years were included in this descriptive analytic study. Total self-concept score for each child was assessed according to Primary Self-concept Scale before dental treatment. Child’s anxiety and child’s behavior were assessed, during the restoration of mandibular primary molar, using clinical anxi-ety rating scale and Frankl Scale, respectively. Spearman’s correlation coefficient was used to evaluate the correlation be-tween the total self-concept score with the results of clinical anxiety rating scale and Frankl Scale. Results. There was a moderate inverse correlation between the self-concept and clinical anxiety rating scale scores (r = −0.545, P < 0.001, and a moderate correlation between the self-concept and child’s behavior scores (r = 0.491, P < 0.001. A strong inverse relation was also found between the anxiety and behavior scores (r = −0.91, P < 0.001. Conclusion. Children with higher self-concept had lower anxiety level and better behavioral feedback during dental treat-ment.

  4. The Environmental Kuznets Curve (EKC) theory—Part A: Concept, causes and the CO2 emissions case

    Kaika, Dimitra; Zervas, Efthimios

    2013-01-01

    The main purpose of this study is to capture the main features of the Environmental Kuznets Curve (EKC)-concept. According to the EKC-theory, the process of economic growth is expected eventually to limit the environmental degradation created in the early stages of development. The EKC concept leads many researchers from the early 1990s to assume that each economy should focus on its growth, and any environmental problems will be eventually eliminated by the process of economic growth. Several studies attempt to test empirically the EKC-hypothesis using data on many countries and examining various types of environmental degradation, while other studies examine the underlying factors that may drive such a relationship. This article reviews the evolution of the EKC-concept and the possible causes of an EKC-pattern, like the distribution of income, the international trade (pollution haven hypothesis), structural changes, technical progress and improvements in energy efficiency, institutions and governance and consumer preferences. As CO 2 emissions are a pollutant with global effects, several studies deal with the possible EKC-pattern for CO 2 emissions and these studies are discussed separately. The various critiques on the EKC-concept are reviewed in the second article of this work. - Highlights: • The evolution to the EKC-concept and the EKC-speculation is presented. • The possible factors—other than income—that may lead to an EKC-relationship are analyzed. • The EKC literature is quite large, and results are at best mixed. No clear conclusion can be drawn. • The relationship between income and CO 2 emissions comes up to be positive due to energy consumption

  5. Molten salt reactor concept

    Sood, D.D.

    1980-01-01

    Molten salt reactor is an advanced breeder concept which is suited for the utilization of thorium for nuclear power production. This reactor is based on the use of solutions of uranium or plutonium fluorides in LiF-BeF 2 -ThF 4 as fuel. Unlike the conventional reactors, no external coolant is used in the reactor core and the fuel salt itself is circulated through heat exchangers to transfer the fission produced heat to a secondary salt (NaF-NaBF 4 ) for steam generation. A part of the fuel stream is continuously processed to isolate 233 Pa, so that it can decay to fissile 233 U without getting converted to 234 Pa, and for the removal of neutron absorbing fission products. This on-line processing scheme makes this reactor concept to achieve a breeding ratio of 1.07 which is the highest for any thermal breeder reactor. Experimental studies at the Bhabha Atomic Research Centre, Bombay, have established the use of plutonium as fuel for this reactor. This molten salt reactor concept is described and the work conducted at the Bhabha Atomic Research Centre is summarised. (auth.)

    Arafah, Y.; Winarso, H.

    2017-06-01

    The smart city concept originally aimed at dealing with various urban problems, in particular, those related to the urban environment and infrastructure, such as modeling transport flow in a city. As it developed, the concept is now widely used to accelerate the process of urban management by using IT technology and by the availability of big data. However, the smart city discourses are still debated. There is a number of critical literature on the discourses; some are more concerned with the use and development of information communication technology (ICT). ICT and modern technology are considered the key aspect of the smart city concept. Meanwhile, others emphasize the importance of the people who operate the technology. Very few, if any, literature emphasizes the importance of resilience in the smart city discourse. The city as a complex system should have the ability to be resilient, especially when technology fails either due to technical/man-made or natural disasters. This paper aims to redefine the smart city concept in urban planning through a literature study in the context of planning using a resilience approach. This paper describes and defines what the smart city concept is, what it means, as well as explains the relation and linkage of the importance of using resilience approach in defining the smart city. Factors of resilience will lead to a soft infrastructure approach, such as enhancement in many aspects, e.g. community capacity, social and human capital, knowledge inclusion, participation, social innovation, and social equity. Discussion and analysis are conducted through a deep literature study using systematic literature review methodology.

    Full Text Available Customers play a crucial role in innovation processes. Their importance is proved by numerous theories and innovation models which put users and clients in the heart of innovation processes. One of the newest concept, popular in Scandinavian countries, picking up this thread is the User–Driven Innovation (UDI. To increase probability of innovation success consumers must be involved in the firm’s business model / innovation strategy, becoming a part of the innovation processes and all other stakeholders should be aware of the significance and character of the linkage between customer and company. As a result, building, implementing and monitoring of the customer–oriented innovation strategy should take place. The Balanced Scorecard (BSC may turn out to be very helpful in achieving the above. The aim of this paper is to show that BSC may be a device of implementing the User–Driven Innovation concept, helping to understand UDI assumptions and the role of customers in creating value. Examples of strategic goals and performance indicators presented in this paper may be used by enterprises, which intend to build UDI-based BSC.

    2008-11-01

    The aim of this paper is to report a concept analysis of maternal sensitivity. Maternal sensitivity is a broad concept encompassing a variety of interrelated affective and behavioural caregiving attributes. It is used interchangeably with the terms maternal responsiveness or maternal competency, with no consistency of use. There is a need to clarify the concept of maternal sensitivity for research and practice. A search was performed on the CINAHL and Ovid MEDLINE databases using 'maternal sensitivity', 'maternal responsiveness' and 'sensitive mothering' as key words. The searches yielded 54 records for the years 1981-2007. Rodgers' method of evolutionary concept analysis was used to analyse the material. Four critical attributes of maternal sensitivity were identified: (a) dynamic process involving maternal abilities; (b) reciprocal give-and-take with the infant; (c) contingency on the infant's behaviour and (d) quality of maternal behaviours. Maternal identity and infant's needs and cues are antecedents for these attributes. The consequences are infant's comfort, mother-infant attachment and infant development. In addition, three positive affecting factors (social support, maternal-foetal attachment and high self-esteem) and three negative affecting factors (maternal depression, maternal stress and maternal anxiety) were identified. A clear understanding of the concept of maternal sensitivity could be useful for developing ways to enhance maternal sensitivity and to maximize the developmental potential of infants. Knowledge of the attributes of maternal sensitivity identified in this concept analysis may be helpful for constructing measuring items or dimensions.

  13. From Perceptual Categories to Concepts: What Develops?

    2010-01-01

    People are remarkably smart: they use language, possess complex motor skills, make non-trivial inferences, develop and use scientific theories, make laws, and adapt to complex dynamic environments. Much of this knowledge requires concepts and this paper focuses on how people acquire concepts. It is argued that conceptual development progresses from simple perceptual grouping to highly abstract scientific concepts. This proposal of conceptual development has four parts. First, it is argued that categories in the world have different structure. Second, there might be different learning systems (sub-served by different brain mechanisms) that evolved to learn categories of differing structures. Third, these systems exhibit differential maturational course, which affects how categories of different structures are learned in the course of development. And finally, an interaction of these components may result in the developmental transition from perceptual groupings to more abstract concepts. This paper reviews a large body of empirical evidence supporting this proposal. PMID:21116483

    We present an update on the Sun Radio Interferometer Space Experiment (SunRISE) mission concept, which was selected for a Step 2 study as part of the Small Explorer (SMEX) Mission of Opportunity (MoO) call. SunRISE is space-based sparse array, composed of six 6U CubeSats, designed to localize the radio emission associated with coronal mass ejections (CMEs) from the Sun. Radio emission from CMEs is a direct tracer of the particle acceleration in the inner heliosphere and potential magnetic connections from the lower solar corona to the larger heliosphere. Furthermore, CME radio emission is quite strong such that only a relatively small number of antennas is required, and a small mission would make a fundamental advancement. Indeed, the state-of-the-art for tracking CME radio emission is defined by single antennas (Wind/WAVES, Stereo/SWAVES) in which the tracking is accomplished by assuming a frequency-to-density mapping. This type of Heliophysics mission would be inherently cost prohibitive in a traditional spacecraft paradigm. However, the use of CubeSats, accompanied by the miniaturization of subsystem components, enables the development of this concept at lower cost than ever before. We present the most recent updates on this mission concept, starting from the concept's performance as compared to the required science and driving technical requirements. We then focus on the SunRISE mission concept of operations, which consists of six 6U CubeSats placed in a GEO graveyard orbit for 6 months to achieve the aforementioned science goals. The spacecraft fly in a passive formation, which allows them to form an interferometer while minimizing the impact on operations complexity. We also present details of the engineering design and the key trades being performed as part of the Step 2 concept study.

  2. Basic concepts for designing renewable electricity support aiming at a full-scale transition by 2050

    International Nuclear Information System (INIS)

    Verbruggen, Aviel; Lauber, Volkmar

    2009-01-01

    Renewable electricity supply is a crucial factor in the realization of a low-carbon energy economy. The understanding is growing that a full turn-over of the electricity sectors by 2050 is an elementary condition for avoiding global average temperature increase beyond 2 C. This article adopts such full transition as Europe's target when designing renewable energy policy. An immediate corollary is that phasing-in unprecedented energy efficiency and renewable generation must be paralleled by phasing-out non-sustainable fossil fuel and nuclear power technologies. The double phasing programme assigns novel meaning to nearby target settings for renewable power as share of total power consumption. It requires organizing in the medium term EU-wide markets for green power, a highly demanding task in the present context of poorly functional markets in brown power. The EU Commission's 2007/2008 proposals of expanding tradable certificates markets were not based on solid analysis of past experiences and future necessities. The keystone of sound policies on renewable electricity development is a detailed scientific differentiation and qualification of renewable electricity sources and technologies, for measuring the huge diversity in the field. We provide but structuring concepts about such qualification, because implementation requires extensive research resources. Support for renewable electricity development is organized via feed-in prices or premiums, and via quota obligations connected to tradable green certificates. Green certificates are dependent on physical generated renewable power, but separable and no joint products. Contrary to conventional wisdom we argue their separation in cost analysis but firm linking during trade. A few graphs illustrate the importance of assigning qualities to different renewable power sources/technologies. Feed-in systems based on an acceptable qualification perform generally better than certificate markets imposing uniform approaches on a

    An important part of the Department of Energy (DOE) Weapons Complex Reconfiguration (WCR) Program is the development of facilities for long-term storage of plutonium. The WCR design goals are to provide storage for metals, oxides, pits, and fuel-grade plutonium, including material being held as part of the Strategic Reserve and excess material. Major activities associated with plutonium storage are sorting the plutonium inventory, material handling and storage support, shipping and receiving, and surveillance of material in storage for both safety evaluations and safeguards and security. A variety of methods for plutonium storage have been used, both within the DOE weapons complex and by external organizations. This paper discusses the advantages and disadvantages of proposed storage concepts based upon functional criteria. The concepts discussed include floor wells, vertical and horizontal sleeves, warehouse storage on vertical racks, and modular storage units. Issues/factors considered in determining a preferred design include operational efficiency, maintenance and repair, environmental impact, radiation and criticality safety, safeguards and security, heat removal, waste minimization, international inspection requirements, and construction and operational costs

As part of this project EnerSys-ABSL has explored five novel deployable structure concepts. This paper presents the top level definition of these concepts together with the requirements considered in the design and selection of the preferred candidate. These new concepts are described and then compared through a trade-off analysis to identify the most suitable concept that EnerSys-ABSL would like to consider for the breadboard demonstrator. Finally, the kinematics of the chosen concept is described in more detail and future steps in the development process are highlighted.

    The concepts of liquid metals, due to their large spectrum, show important possibility of sustainable development: two concepts of liquid metal (Sodium and Lead) were engaged in the frame of the IV generation. The reactors with sodium benefit from considerable background of experience and of important work on projects to aim at the price diminution and the increase of safety (EFR, JSFR). The commitment of Japan as a leader of this concept and the support by France allow to contemplate an industrial deployment from 2015. The lead reactors offer some advantages in the domain of safety but otherwise require a highly important research and development binded to the control of the corrosion, the perspective of deployment of this concept are more hypothetical

    2018-01-01

    In 2015, the National Aeronautics and Space Administration (NASA) formed a multi-center, interdisciplinary team of engineers from three different aeronautics research centers who were tasked with improving NASA autonomy research capabilities. This group was subsequently named the Aeronautics Autonomy Testbed Capability (AATC) team. To aid in confronting the autonomy research directive, NASA contracted IDEO, a design firm, to provide consultants and guides to educate NASA engineers through the practice of design thinking, which is an unconventional method for aerospace design processes. The team then began learning about autonomy research challenges by conducting interviews with a diverse group of researchers and pilots, military personnel and civilians, experts and amateurs. Part of this design thinking process involved developing ideas for products or programs known as concepts that could enable real world fulfillment of the most important latent needs identified through analysis of the interviews. The concepts are intended to be sacrificial, intermediate steps in the design thinking process and are presented in this report to record the efforts of the AATC group. Descriptions are provided in present tense to allow for further ideation and imagining the concept as reality as was attempted during the teams discussions and interviews. This does not indicate that the concepts are actually in practice within NASA though there may be similar existing programs independent of AATC. These concepts were primarily created at two distinct stages during the design thinking process. After the initial interviews, there was a workshop for concept development and the resulting ideas are shown in this work as from the First Round. As part of succeeding interviews, the team members presented the First Round concepts to refine the understanding of existing research needs. This knowledge was then used to generate an additional set of concepts denoted as the Second Round. Some

    The issue of cross-subsidies and cost allocation practices concerns a large part of debates facing the deregulation of electric public utilities. The first aim of this paper is to deal with the regulation of an electric multi-product monopoly in association with equity and efficiency dimensions. To this end, we develop a concept and measure of improved equity. From a practical point of view, we also try to compute improved equity measurement considering the case of EDF tariff for domestic customers. (author)

  12. A New Virtual Point Detector Concept for a HPGe detector

    Byun, Jong In; Yun, Ju Yong

    2009-01-01

    For last several decades, the radiation measurement and radioactivity analysis techniques using gamma detectors have been well established. Especially , the study about the detection efficiency has been done as an important part of gamma spectrometry. The detection efficiency depends strongly on source-to-detector distance. The detection efficiency with source-to-detector distance can be expressed by a complex function of geometry and physical characteristics of gamma detectors. In order to simplify the relation, a virtual point detector concept was introduced by Notea. Recently, further studies concerning the virtual point detector have been performed. In previous other works the virtual point detector has been considered as a fictitious point existing behind the detector end cap. However the virtual point detector position for the front and side of voluminous detectors might be different due to different effective central axis of them. In order to more accurately define the relation, therefore, we should consider the virtual point detector for the front as well as side and off-center of the detector. The aim of this study is to accurately define the relation between the detection efficiency and source-to-detector distance with the virtual point detector. This paper demonstrates the method to situate the virtual point detectors for a HPGe detector. The new virtual point detector concept was introduced for three area of the detector and its characteristics also were demonstrated by using Monte Carlo Simulation method. We found that the detector has three virtual point detectors except for its rear area. This shows that we should consider the virtual point detectors for each area when applying the concept to radiation measurement. This concept can be applied to the accurate geometric simplification for the detector and radioactive sources.

    The value of collaborative concept mapping in assisting students to develop an understanding of complex concepts across a broad range of basic and applied science subjects is well documented. Less is known about students' learning processes that occur during the construction of a concept map, especially in the context of clinical cases in veterinary medicine. This study investigated the unfolding collaborative learning processes that took place in real-time concept mapping of a clinical case by veterinary medical students and explored students' and their teacher's reflections on the value of this activity. This study had two parts. The first part investigated the cognitive and metacognitive learning processes of two groups of students who displayed divergent learning outcomes in a concept mapping task. Meaningful group differences were found in their level of learning engagement in terms of the extent to which they spent time understanding and co-constructing knowledge along with completing the task at hand. The second part explored students' and their teacher's views on the value of concept mapping as a learning and teaching tool. The students' and their teacher's perceptions revealed congruent and contrasting notions about the usefulness of concept mapping. The relevance of concept mapping to clinical case-based learning in veterinary medicine is discussed, along with directions for future research.

  18. Proposal of a weight factor for alpha radiation aiming biota radioprotection

    International Nuclear Information System (INIS)

    Pereira, Wagner de S.; Py Junior, Delcy de A.; Kelecom, Alphonse; Goncalves, Simone

    2009-01-01

    Several proposals based on the environmental radioprotection of calculating the absorbed dose in biota have been suggested. The absorbed dose expresses the deposition of energy per mass unit. The differences in biological effects of the absorbed dose can be quantified by applying a correction factor to the absorbed dose. The correction factor for radiation is easier to establish, because radiations exist in smaller number (alpha, beta, neutrons and photons) and can be set for groups of organisms. This work aims to propose a correction factor for radiation, in order to adequate the concept of absorbed dose currently used to the concept of equivalent dose. A survey of the literature on correction factors proposed for alpha radiation was carried out and, when possible, the biological endpoint was identified, as well as the radionuclide and the biological target. A variation of the weight factor for alpha radiation from 1 to 377 was observed and a number of biological endpoints, biological target and alpha emitter radionuclide were identified. Finally we propose a weight value for alpha radiation of 40, and we propose also the name of correction factor for radiation alpha as being ecological radiation weighting factor (WRE) the name 'equivalent dose for flora and fauna' (HTFF) to name of the new dose.

  19. Against compassion: in defence of a "hybrid" concept of empathy.

    Science.gov (United States)

    Morgan, Alastair

    2017-07-01

    In this article, I argue that the recent emphasis on compassion in healthcare practice lacks conceptual richness and clarity. In particular, I argue that it would be helpful to focus on a larger concept of empathy rather than compassion alone and that compassion should be thought of as a component of this larger concept of empathy. The first part of the article outlines a critique of the current discourse of compassion on three grounds. This discourse naturalizes, individualizes, and reifies compassion leading to a decontextualized and simplified understanding of failures in healthcare practice. The second part uses resources from phenomenology and contemporary moral philosophy to construct a "hybrid" concept of empathy that includes both pre-reflective/intuitive and cognitive/imaginative components. This "hybrid" concept of empathy leads to a more complex understanding of the multiple responses to others' distress. I conclude that there are no straightforward normative naturalistic responses to others' distress. Rather than conceptualizing compassion as a naturalistic impulse or a character-based trait, we need to consider the complexity of our empathic recognition of vulnerable others. © 2016 John Wiley & Sons Ltd.

    The European Union has been engaged since 1989 in a programme to develop tritium breeding blankets for application in a fusion power reactor. There are four concepts under development, namely two of the solid breeder type and two of the liquid breeder type. At the Forschungszentrum Karlsruhe one blanket concept of each line has been pursued so far with the so-called dual coolant type representing the liquid breeder line. In the dual coolant concept the breeder material (Pb-17Li) is circulated to external heat exchangers to carry away the bulk of the generated heat and to extract the tritium. Additionally, the heavily loaded first wall is cooled by high pressure helium gas. The safety and environmental impact of the dual coolant blanket concept has been assessed as part of the blanket concept selection excercise, a European concerted action, aiming at selecting the two most promising concepts for futher development. The topics investigated are: (a) Blanket materials and toxic materials inventory, (b) energy sources for mobilisation, (c) fault tolerance, (d) tritium and activation products release, and (e) waste generation and management. No insurmountable safety problems have been identified for the dual coolant blanket. The results of the assessment are described in this report. The information collected is also intended to serve as input to the EU 'Safety and Environmental Assessment of Fusion longterm Programme' (SEAL). The unresolved issues pertaining to the dual coolant blanket which would need further investigations in future programmes are outlined herein. (orig.) [de

    2009-01-01

    Future development in neurorehabilitation depends upon bringing together the endeavors of basic science and clinical practice. The Bobath concept is widely utilized in rehabilitation following stroke and other neurological conditions. This concept was first developed in the 1950s, based on the neuroscience knowledge of those times. The theoretical basis of the Bobath concept is redefined based on contemporary neuroscience and rehabilitation science. The framework utilized in the Bobath concept for the analysis of movement and movement dysfunction is described. This framework focuses on postural control for task performance, the ability to move selectively, the ability to produce coordinated sequences of movement and vary movement patterns to fit a task, and the role of sensory input in motor behaviour and learning. The article describes aspects of clinical practice that differentiate this approach from other models of practice. Contemporary practice in the Bobath concept utilizes a problem-solving approach to the individual's clinical presentation and personal goals. Treatment is focused toward remediation, where possible, and guiding the individual towards efficient movement strategies for task performance. The aim of this article is to provide a theoretical framework on which future research into the Bobath concept can be based.

    Full Text Available In this study, we aim to investigate how students build interaction between concepts and figure in geometry. For this purpose we developed two type data collection tool. First one called shapely is formed eight open ended question which has concepts and figure. Second one called shapeless is formed eight open ended question which has only concepts. To prepare this data collection tools’ difficulty level we took two math teachers’ opinions. Developed data collection tools were applied 120 students at 9th grade and 11th grade in Trabzon Gazi Anatolian High School. First of all we applied shapeless questions. One month later we applied shapely questions. We investigated students’ answer and the data showed that students more succeed in shapely questions than shapeless questions. We concluded that the difficulty of solving shapeless question result from students didn’t manage to draw figure representing concept knowledge or draw wrong figure, figure drawn by students can’t fulfıl generalizability condition and students who have little knowledge of concept in geometry is under the influence of prototype figure.Key Words:    Figural concepts theory, geometrical reasoning, geometry teaching

    Cognitive models suggest that the self-concept of persons with psychosis can be fundamentally affected. Self-concepts were found to be related to different symptom domains when measured concurrently. Longitudinal investigations to disentangle the possible causal associations are rare. We examined a sample of 160 people with a diagnosis of schizophrenia who took part in a psychotherapy study. All participants had the DSM-IV diagnosis of a schizophrenia and pronounced negative symptoms. Neurocognition, symptoms, and self-concepts were assessed at two time points 12 months apart. Structural equation modeling was used to test whether symptoms influence self-concepts (scar-model) or self-concepts affect symptoms (vulnerability model). Negative symptoms correlated concurrently with self-concepts. Neurocognitive deficits are associated with more negative self-concepts 12 months later. Interpersonal self-concepts were found to be relevant for paranoia. The findings implicate that if deficits in neurocognition are present, fostering a positive self-concept should be an issue in therapy. Negative interpersonal self-concept indicates an increased risk for paranoid delusions in the course of 1 year. New aspects for cognitive models in schizophrenia and clinical implications are discussed.

    2017-12-01

    Full Text Available Restoration of the anatomy of the hip joint and biomechanics across it, carry the immense importance to prevent future osteoarthritis of the joint. The aim of this review is to provide the brief concept of the methods to preserve the hip, especially in young adults. Attempts to preserve the hips start with the intense preoperative planning of the corrective procedure. Different parameters regarding the femur and acetabulum in all 3 dimensions need to be assessed. Especially, measurement of the anteversion of the femur and acetabulum is a significant step to avoid osteoarthritis. In addition, the suprapelvic and infrapelvic (spine and lower limb lengths alignment needs to be considered in the planning. Correction of the femoral side of the hip needs the understanding of the blood supply of the proximal femur which carries the risk of avascular necrosis more so with intracapsular osteotomies. Acetabular reorientation, to re-distribute the forces over the weight bearing part, can be carried out with re-directional osteotomy such as periacetabular osteotomy. It needs the understanding of the acetabular anatomy and the force distribution in it. To conclude, correction of both femoral and acetabular side parameters need to be considered in decision making depending on the alterations due to various etiologies causing the hip disorders.

Namely, in the light of the cognitive linguistics, meaning is considered to be not only a linguistic phenomenon, but a conceptual phenomenon as well. Such vantage point enables a lexico-semantic interpretation of linguistic units from a conceptual perspective, which includes the forming of correspondences between two concepts, with one concept being understood in terms of the other. The analysis includes 24 Business English idioms which stem from the conceptual domain of GAME/SPORT and is aimed at establishing the conceptual mapping (primarily via a cognitive mechanism known as the conceptual metaphor between the above stated source and the target domains, which prove a potential understanding of the concept of BUSINESS on the basis of the concepts of SPORT and GAME.

    The investigation is divided in 7 chapters and aims to argue for the realizability of a new conception of 'fundamental time asymmetries' in physics. After an introduction (chapter 1) in the field of interest, the investigation continues by developing a conception of fundamentality for time asymmetries in chapter 2. Chapter 3 shows that this conception is realized in classical cosmology and chapter 4 demonstrates, by taking in to account the result from chapter 3, that classical electrodynamics is understandable as a time asymmetric theory. Chapter 5 focuses on time asymmetries in quantum cosmology as well as quantum thermodynamics and demonstrates - as in the classical case - that a fundamental time asymmetry is imbedded in those fields. The considerations, contained in chapter 6, are focused on non relativistic quantum mechanics (NRQM). Here the main aim is to demonstrate that NRQM can be understood as a time asymmetric theory - even without using the measurement-process for that purpose. Chapter 7 summarized the main arguments and conclusions.

    Full Text Available Malgré la popularité du concept d’assimilation en sciences sociales, on connaît finalement peu de chose sur son origine intellectuelle. Cet article vise à faire la généalogie de ce concept dans une perspective franco-britannique. Sa traduction du latin vers le français et l’anglais conserve la signification de « similitude » mais le concept se sécularise, d’une part, à travers le langage des sciences naturelles dont l’influence favorise une réappropriation pour décrire les relations humaines et, d’autre part, le discours historique anglais et le discours politique colonial français. Dans le contexte britannique, l’assimilation devient une qualité collective attribuée à tout un peuple, puis utilisée en naturalisant les différences entre les peuples pour les rendre irréductibles et enfin s’enrichit d’une acception administrative. En France, la politisation du concept d’assimilation dans les discours et réglementations coloniaux provoque un bouleversement sémantique qui l’associe au concept d’égalité.

    Full Text Available The relationship between self-concept and societal settings has been widely investigated in several Western and Asian countries, with respect to the academic self-concept in an educational environment. Although the musical self-concept is highly relevant to musical development and performance, there is a lack of research exploring how the musical self-concept evolves in different cultural settings and societies. In particular, there have been no enquiries yet in the Chinese music education environment. This study’s goal was the characterization of musical self-concept types among music students at a University in Beijing, China. The Musical Self-Concept Inquiry (MUSCI—including ability, emotional, physical, cognitive, and social facets—was used to assess the students’ musical self-concepts (N=97. The data analysis led to three significantly distinct clusters and corresponding musical self-concept types.

    The relationship between self-concept and societal settings has been widely investigated in several Western and Asian countries, with respect to the academic self-concept in an educational environment. Although the musical self-concept is highly relevant to musical development and performance, there is a lack of research exploring how the musical self-concept evolves in different cultural settings and societies. In particular, there have been no enquiries yet in the Chinese music education environment. This study's goal was the characterization of musical self-concept types among music students at a University in Beijing, China.

  3. Feasibility Criteria for Interval Management Operations as Part of Arrival Management Operations

    Levitt, Ian M.; Weitz, Lesley A.; Barmore, Bryan E.; Castle, Michael W.

    2014-01-01

    Interval Management (IM) is a future airborne spacing concept that aims to provide more precise inter-aircraft spacing to yield throughput improvements and greater use of fuel efficient trajectories for arrival and approach operations. To participate in an IM operation, an aircraft must be equipped with avionics that provide speeds to achieve and maintain an assigned spacing interval relative to another aircraft. It is not expected that all aircraft will be equipped with the necessary avionics, but rather that IM fits into a larger arrival management concept developed to support the broader mixed-equipage environment. Arrival management concepts are comprised of three parts: a ground-based sequencing and scheduling function to develop an overall arrival strategy, ground-based tools to support the management of aircraft to that schedule, and the IM tools necessary for the IM operation (i.e., ground-based set-up, initiation, and monitoring, and the flight-deck tools to conduct the IM operation). The Federal Aviation Administration is deploying a near-term ground-automation system to support metering operations in the National Airspace System, which falls within the first two components of the arrival management concept. This paper develops a methodology for determining the required delivery precision at controlled meter points for aircraft that are being managed to a schedule and aircraft being managed to a relative spacing interval in order to achieve desired flow rates and adequate separation at the meter points.

    The aim of this poster is to present a proposal of how concept maps may be described, annotated and exposed on the Web of Data, also frequently known as the Semantic Web or Web 3.0. In doing so, the poster will first introduce the concept ofconcept maps 3.0 – that is, concept maps which utilize......, and are enriched by, Web 3.0 technologies and resources. While conceptmaps 1.0 and 2.0 may be said to reflect earlier generations of the Web, the web of documents and the social web, the utilization ofWeb 3.0 technologies allows concept maps 3.0 to become machine-interpretable semantic web resources, and perhaps...... even semantic learning resources. This has several implications. One is that concept map discoverability can undoubtedly be improved through metadata annotation and the use of search engine interpretable vocabularies such as hts://schema.org/. Also, a key featureof Web 3.0 is that it supports...

    The Healthy Start-Départ Santé intervention was developed to promote physical activity, gross motor skills and healthy eating among preschoolers attending childcare centers. This process evaluation aimed to report the reach, effectiveness, adoption, implementation and maintenance of the Healthy Start-Départ Santé intervention. The RE-AIM framework was used to guide this process evaluation. Data were collected across 140 childcare centers who received the Healthy Start-Départ Santé intervention in the provinces of Saskatchewan and New Brunswick, Canada. Quantitative data were collected through director questionnaires at 10 months and 2 years after the initial training and analyzed using descriptive statistics. Qualitative data were collected throughout the intervention. The intervention was successful in reaching a large number of childcare centres and engaging both rural and urban communities across Saskatchewan and New Brunswick. Centres reported increasing opportunities for physical activity and healthy eating, which were generally low-cost, easy and quick to implement. However, these changes were rarely transformed into formal written policies. A total of 87% of centers reported using the physical activity resource and 68% using the nutrition resource on a weekly basis. Implementation fidelity of the initial training was high. Of those centers who received the initial training, 75% participated in the mid-point booster session training. Two year post-implementation questionnaires indicated that 47% of centers were still using the Active Play Equipment kit, while 42% were still using the physical activity resource and 37% were still using the nutrition resource. Key challenges to implementation and sustainability identified during the evaluation were consistent among all of the REAIM elements. These challenges included lack of time, lack of support from childcare staff and low parental engagement. Findings from this study suggest the implementation of

    Keller, John Michael

    This work presents two research efforts, one involving planetary science education research and a second involving the surface composition of Mars. In the former, student beliefs and reasoning difficulties associated with the greenhouse effect were elicited through student interviews and written survey responses from >900 US undergraduate non-science majors. This guided the development of the Greenhouse Effect Concept Inventory (GECI), an educational research tool designed to assess pre- and post-instruction conceptual understanding of the greenhouse effect. Three versions of this multiple-choice instrument were administered to >2,500 undergraduates as part of the development and validation process. In contrast to previous research efforts regarding causes, consequences, and solutions to the enhanced greenhouse effect, the GECI focuses primarily on the physics of energy flow through Earth's atmosphere. The GECI is offered to the science education community as a research tool for assessing instructional strategies on this topic. It was confirmed that the study population subscribes to several previously identified beliefs. These include correct understandings that carbon dioxide is an important greenhouse gas and the greenhouse effect increases planetary surface temperatures. Students also commonly associate the greenhouse effect with increased penetration of sunlight into and trapping of solar energy in the atmosphere. Students intermix concepts associated with the greenhouse effect, global warming, and ozone depletion. Reinforcing the latter concept, a majority believe that the Sun radiates most of its energy as ultraviolet light. Students also describe inaccurate and incomplete trapping models, which include permanent trapping, trapping through reflection, and trapping of gases and pollution. Another reasoning difficulty involves the idea that Earth's surface radiates energy primarily during the nighttime. The second research effort describes the distribution of

    2018-01-01

    The aim of this concept analysis is to clarify the meaning of professional nursing values. In a time of increasing ethical dilemmas, it is essential that nurses internalize professional values to develop and maintain a professional identity. However, nursing organizations and researchers provide different conceptions of professional nursing values, leading to a lack of clarity as to the meaning and attributes of this construct. Walker and Avant's (2011) method was used to guide an analysis of this concept. Resources published from 1973 to 2016 were identified via electronic databases and hand-searching of reference lists. A review of the literature was completed and the data were analyzed to identify uses of the concept; the defining attributes of the concept; borderline, related, contrary, and illegitimate examples; antecedents and consequences; and empirical referents. Professional nursing values were defined as important professional nursing principles of human dignity, integrity, altruism, and justice that serve as a framework for standards, professional practice, and evaluation. Further research is needed in the development and testing of professional nursing values theory, and the reassessment of values instruments. Core professional values that are articulated may help unify the profession and demonstrate the value of nursing to the public. © 2017 Wiley Periodicals, Inc.

  10. Concepts of magnetospheric convection

    1975-01-01

    Magnetospheric physics, which grew out of attempts to understand the space environment of the Earth, is becoming increasingly applicable to other systems in the Universe. Among the planets, in addition to the Earth, Jupiter, Mercury, Mars and (in a somewhat different way) Venus are now known to have magnetospheres. The magnetospheres of pulsars have been regarded as an essential part of the pulsar phenomenon. Other astrophysical systems, such as supernova remnant shells or magnetic stars and binary star systems, may be describable as magnetospheres. The major concepts of magnetospheric physics thus need to be formulated in a general way not restricted to the geophysical context in which they may have originated. Magnetospheric convection has been one of the most important and fruitful concepts in the study of the Earth's magnetosphere. This paper describes the basic theoretical notions of convection in a manner applicable to magnetospheres generally and discusses the relative importance of convective corotational motions, with particular reference to the comparison of the Earth and Jupiter.

    Mehmet Cagrı Gundogdu

    2012-01-01

    Full Text Available This paper aims to show an understanding of the vague issues on the relations among the concepts of entrepreneurship, intrapreneurship and innovation. Some of the greatest intellectual challenges of our time are emerging from the huge study of business management and organization. Through these issues; creating and applying smart ideas that form the practice of business and management, namely entrepreneurial activities, have been noticeably stepping forward for more than three decades. An updated entrepreneurial view in business and management is crucial for reaching the aim of innovation; besides, as it’s mentioned above, this perspective deserves to be scrutinized deeply in order to obtain a full understanding of the key concepts of entrepreneurship, intrapreneurship, and innovation also to provide a lean conclusion, which is mainly based on the dual and multi-relations of the related terms. The approach taken in the literature, generally construes entrepreneurship as the main concept regarding entrepreneurial thought; intrapreneurship as its sub-concept; and considers innovation as redundant to include in some of the entrepreneurial definitions; though it’s not totally been ignored. However, the new economical framework has proven that a fresh insight is required from now on, in order to explain how to survive in this rapidly changing environment.  From this perspective, the main questions of this paper are: Can the concepts of entrepreneurship, intrapreneurship and innovation be appraised in an integrative approach, contemporarily? In other words, can these concepts be united under the umbrella of a valid single term different from these? If yes, how should the new concept be discussed and what are the attributes of the new character emerging from this concept?

    The ALICE Detector Control System (DCS) is in charge of control and operation of one of the large high energy physics experiments at CERN in Geneva. The DCS design which started in 2000 was partly inspired by the control systems of the previous generation of HEP experiments at the LEP accelerator at CERN. However, the scale of the LHC experiments and the use of modern, "intelligent" hardware and the harsh operational environment led to an innovative system design. The overall architecture has been largely based on commercial products like PVSS SCADA system and OPC servers extended by frameworks. Windows has been chosen as the operating system platform for the core systems and Linux for the front-end devices. The concept of finite state machines has been deeply integrated into the system design and the design principles have been optimized and adapted to the expected operational needs. The ALICE DCS was designed, prototyped, and developed at a time when no experience with systems of similar s...

  14. H12: Examination of safety assessment aims, procedures and results from a wider perspective

    Neall, F.B; Smith, P.A.

    2004-04-01

    Safety assessment (SA) are a familiar tool for the evaluation of disposal concepts for radioactive waste. There is, however, often confusion in the wider community about the aims, methods and results used in SA. This report aims to present the H12 SA in a way that makes the assessment process clearer and the implications of the results more meaningful both to workers within the SA field and to a wider technical audience. The reasonableness of the assessment results, the quality of the models and databases and redundancy within the natural and engineered barrier system have been considered. A number of recent and somewhat older SAs that address a range of different waste types, host rocks and disposal concepts have been considered, and comparisons made to H12. A further aim is to put both doses and timescales in a more meaningful context. It has been necessary to: consider ways of demonstrating the meaningfulness of calculations that give results for many thousands of years in the future; provide a framework timescale as a context for SA results over long times; demonstrate the smallness of the risk associated with the doses by comparison with other radiological and non-radiological risks. The perception of risk, which is a critical issue for public acceptance of radioactive waste disposal and must be considered when seeking to present safety assessment results 'in perspective' to a wider audience, is also discussed. It is concluded that H12 is comparable in many ways to assessments carried out internationally. Some assumptions are somewhat arbitrary reflecting the generic stage of the Japanese programme, and are likely to become better founded in future exercises. Nevertheless, H12 provides a clear and well-founded message that it is feasible to site and construct a safe repository from HLW in Japan. (author)

    2015-01-01

    This study aimed to describe the meaning of the concept 'workplace incivility' and promote consistency in its application in nursing research and practice. The methodology introduced by Walker and Avant was used to analyze this concept. A total number of 50 studies that had essentially addressed the concept of incivility in employees' work environment was selected. Ambiguous intent, violation of mutual respect, low intensity and lack of physical assault were identified as the defining attributes of workplace incivility. The necessary antecedent of workplace incivility consisted of the presence of two or more people, with one or more as the source of the incivility, and another or others as its target in the workplace. Moreover, certain individual and organisational factors were the potential antecedents of workplace incivility. Possible negative outcomes for victims, witnesses, organisations, society and perpetrators of such behaviours, such as increased cost for the organisation, reduced citizenship performance, psychological distress and anxiety were identified as outcomes of workplace incivility. Results of the current concept analysis can guide nurse managers to design interventions so that the occurrence of workplace incivility can be reduced. Further studies can focus on testing the psychometric properties of the existing workplace incivility scales, especially uncivil behaviours experienced by nurses across different societies or cultures.

  17. A minimum-size tokamak concept for conditions near ignition

    International Nuclear Information System (INIS)

    Lehnert, B.

    1983-01-01

    Based on a combination of Alcator scaling and a recent theory on the Murakami density limit, a minimum-size tokamak concept (Minitor) is proposed. Even if this concept does not aim at alpha particle containment, it has the important goal of reaching plasma core temperatures and Lawson parameter values required for ignition, by ohmic heating alone and under macroscopically stable conditions. The minimized size, and the associated enhancement of the plasma current density, are found to favour high plasma temperatues, average densities, and beta values. The goal of this concept appears to be realizable by relatively modest technical means. (author)

  18. AN ADAPTIVE ACO-DRIVEN SCHEME FOR LEARNING AIM ORIENTED PERSONALIZED E-LEARNING

    Directory of Open Access Journals (Sweden)

    Sushma Hans

    2014-10-01

    Full Text Available The e-learning paradigm is now a well-established vehicle of modern education. It caters to a wide spectrum of students with diverse backgrounds who enroll with their own learning aims. A core challenge under this scenario is to generate personalized learning paths so that each student can achieve her learning aim most effectively. Prior works used static attributes such as prior knowledge level, learning ability, browsing preferences, learning style etc. to generate personalized learning paths. In this paper, we take an entirely new route by taking into account the continuous improvement of a learner in the light of her own learning aim, to redefine her learning path at each level of the course. We introduce the concept of personalized examination system that systematically evaluates the dynamic learning ability of every student according to her pre-set goals. The proposed intelligent e-learning system uses Ant Colony Optimization to iteratively optimize the forward learning paths. Experimental results reveal that the system is able to tap a student’s improved learning ability to choose more difficult paths that contribute highly towards her own aims. We demonstrate that the overall learning success of weaker students doubles as compared to statically generated paths while there is considerable improvement of 50% in the learning success for average students as well. This clearly indicates that our approach gives realistic benefits to initially weak students who gradually evolve as the course progresses.

    2014-05-01

    The aim of this paper is to evaluate and compare the durability, life expectancy and maintenance needs of traditional Norwegian waterproofing concepts to the generally more rigid waterproofing concepts seen in other European countries. The focus will be on solutions for future Norwegian tunnel boring machine railway tunnels. Experiences from operation of newer and older tunnels with different waterproofing concepts have been gathered and analyzed. In the light of functional requirements for Norwegian rail tunnels, some preliminary conclusions about suitable concepts are drawn. Norwegian concepts such as polyethylene panels and lightweight concrete segments with membrane are ruled out. European concepts involving double shell draining systems (inner shell of cast concrete with membrane) and single shell undrained systems (waterproof concrete segments) are generally evaluated as favorable. Sprayable membranes and waterproof/insulating shotcrete are welcomed innovations, but more research is needed to verify their reliability and cost effectiveness compared to the typical European concepts. Increasing traffic and reliance on public transport systems in Norway result in high demand for durable and cost effective solutions.

    Despite an overwhelming increase in the number of concept analyses published since the early 1970s, there are significant limitations to the impact of this work in promoting progress in nursing science. We conducted an extensive review of concept analyses published between 1972 and 2017 to identify patterns in analysis and followed this with exploration of an exemplar related to the concept of normalization to demonstrate the capabilities of analysis for promoting concept development and progress. Scoping review of peer-reviewed literature published in the Cumulative Index to Nursing and Allied Health Literature (CINAHL) in which the terms "concept analysis," "concept clarification," and "concept derivation" appeared in any part of the reference. The original search returned 3,489 articles. This initial pool was refined to a final sample of 958 articles published in 223 journals and addressing 604 concepts. A review of citations of the original analysis of the concept of normalization resulted in 75 articles selected for closer examination of the process of concept development. Review showed a clear pattern of repetition of analysis of the same concept, growth in number of published analyses, preponderance of first authors with master's degrees, and 43 distinct descriptions of methods. Review of the 75 citations to the normalization analysis identified multiple ways concept analysis can inform subsequent research and theory development. Conceptual work needs to move beyond the level of "concept analysis" involving clear linkage to the resolution of problems in the discipline. Conceptual work is an important component of progress in the knowledge base of a discipline, and more effective use of concept development activities are needed to maximize the potential of this important work. It is important to the discipline that we facilitate progress in nursing science on a theoretical and conceptual level as a part of cohesive and systematic development of the discipline

    Given the wide disagreement over the definition of critical thinking in different disciplines, defining and standardizing the concept according to the discipline of nursing is essential. Moreover, there is limited scientific evidence regarding critical thinking in the context of nursing in Iran. The aim of this study was to analyze and clarify the concept of critical thinking in nursing education in Iran. We employed the hybrid model to define the concept of critical thinking. The hybrid model has three interconnected phases--the theoretical phase, the fieldwork phase, and the final analytic phase. In the theoretical phase, we searched the online scientific databases (such as Elsevier, Wiley, CINAHL, Proquest, Ovid, and Springer as well as Iranian databases such as SID, Magiran, and Iranmedex). In the fieldwork phase, a purposive sample of 17 nursing faculties, PhD students, clinical instructors, and clinical nurses was recruited. Participants were interviewed by using an interview guide. In the analytical phase we compared the data from the theoretical and the fieldwork phases. The concept of critical thinking had many different antecedents, attributes, and consequences. Antecedents, attributes, and consequences of critical thinking concept identified in the theoretical phase were in some ways different and in some way similar to antecedents, attributes, and consequences identified in the fieldwork phase. Finally critical thinking in nursing education in Iran was clarified. Critical thinking is a logical, situational, purposive, and outcome-oriented thinking process. It is an acquired and evolving ability which develops individually. Such thinking process could lead to the professional accountability, personal development, God's consent, conscience appeasement, and personality development. Copyright © 2014.

    Analyses the risks of nuclear power stations. Discusses the security concept of reactors. Analyzes possible crash of air planes on a reactor containment. Presents measures against the spread of radioactivity after a severe accident. Written in engaging style for professionals and policy makers. The book analyses the risks of nuclear power stations. The security concept of reactors is explained. Measures against the spread of radioactivity after a severe accident, accidents of core melting and a possible crash of an air plane on a reactor containment are discussed. The book covers three scientific subjects of the safety concepts of Light Water Reactors: - A first part describes the basic safety design concepts of operating German Pressurized Water Reactors and Boiling Water Reactors including accident management measures introduced after the reactor accidents of Three Mile Island and Chernobyl. These safety concepts are also compared with the experiences of the Fukushima accidents. In addition, the safety design concepts of the future modern European Pressurized Water Reactor (EPR) and of the future modern Boiling Water Reactor SWR-1000 (KERENA) are presented. These are based on new safety research results of the past decades. - In a second, part the possible crash of military or heavy commercial air planes on a reactor containment is analyzed. It is shown that reactor containments can be designed to resist to such an airplane crash. - In a third part, an online decision system is presented. It allows to analyze the distribution of radioactivity in the atmosphere and to the environment after a severe reactor accident. It provides data for decisions to be taken by authorities for the minimization of radiobiological effects to the population. This book appeals to readers who have an interest in save living conditions and some understanding for physics or engineering.

    2017-01-01

    Over the last decade, ‘Energy Justice’ is a concept that has emerged in research across many disciplines. This research explores the role and value of the energy justice concept across the disciplines. It provides the first critical account of the emergence of the energy justice concept in both research and practice. A diagrammatical image for examining the energy justice concepts is presented and this is a tool for interdisciplinary engagement with the concept. In this context, restorative justice is introduced and how it results in energy justice applying in practice is detailed. Energy research scholarship at universities is assessed and it is clear that through universities there is a platform for energy justice scholarship to build on the interdisciplinary energy scholarship at universities. Further, the role of education is vital to policy-making, and the understanding and development of the energy justice concept. Finally, in analysing how the energy justice concept can impact on policy-making, there is a critical examination of the energy justice and its relationship with economics, and how it can transfer directly into practice by assisting in balancing the competing aims of the energy trilemma. - Highlights: • Presents the value of the energy justice concept itself. • Introduces restorative justice as having a key role across the energy justice concept. • Expresses the need to develop a ‘common approach’ for the energy justice concept Advances the conceptual framework for energy justice – from theory to practice.

    The Advanced Industrial Materials (AIM) Program is a part of the Office of Industrial Technologies (OIT), Energy Efficiency and Renewable Energy, US Department of Energy (DOE). The mission of AIM is to support development and commercialization of new or improved materials to improve energy efficiency, productivity, product quality, and reduced waste in the major process industries. OIT has embarked on a fundamentally new way of working with industries--the Industries of the Future (IOF) strategy--concentrating on the major process industries that consume about 90% of the energy and generate about 90% of the waste in the industrial sector. These are the aluminum, chemical, forest products, glass, metalcasting, and steel industries. OIT has encouraged and assisted these industries in developing visions of what they will be like 20 or 30 years into the future, defining the drivers, technology needs, and barriers to realization of their visions. These visions provide a framework for development of technology roadmaps and implementation plans, some of which have been completed. The AIM Program supports IOF by conducting research and development on materials to solve problems identified in the roadmaps. This is done by National Laboratory/industry/university teams with the facilities and expertise needed to develop new and improved materials. Each project in the AIM Program has active industrial participation and support.

    Airport congestion and the associated delays are severe in today's airspace system and are expected to increase. NASA and the FAA is investigating various methods of alleviating this problem through new technology and operational procedures. One concept for improving airspace productivity is time-based control of aircraft. Research to date has focused primarily on the development of time-based flight management systems and Air Traffic Control operational procedures. Flight operations may, however, require special onboard guidance in order to satisfy the Air Traffic Control imposed time constraints. The results are presented of a simulation study aimed at evaluating several time-based guidance concepts in terms of tracking performance, pilot workload, and subjective preference. The guidance concepts tested varied in complexity from simple digital time-error feedback to an advanced time-referenced-energy guidance scheme.

    Full Text Available City logistics is a field that attracts increasing attention of professionals and scientific community and international organizations. Research on problems of urban areas' logistics gives different results and practical solutions. City logistics flows are characterized by partiality, spatial dispersion of generators, diversity in terms of the logistics chains structure, frequency of a large number of smaller shipments, dynamism, stochasticity etc. Problems and the complexity of logistics in urban areas as well as significant decline in the quality of life in modern cities have caused the development of initiatives and concepts of city logistics which should allow the sustainable development of urban areas. The first part of this paper presents the problems of city logistics and impact of logistics activities on urban areas in terms of economic, environmental and social sustainability. The second part presents city logistics initiatives that involve the change of urban area context, in order to improve its sustainability.

    2016-06-01

    Full Text Available This paper aims at discussing the advantages of a methodology design grounded on a concept-based approach to Terminology applied to the most prominent scenario of current Higher Education: blended learning. Terminology is a discipline that aims at representing, describing and defining specialized knowledge through language, putting order into our universe (Nuopponen, 2011. Concepts, as elements of the structure of knowledge (Sager, 1990 emerge as a complex research object. Can they be found in language? A concept-based approach to Terminology implies a clear-cut view of the role of language in terminological work: though language is postulated as being a fundamental tool to grasp, describe and organize knowledge, an isomorphic relationship between language and knowledge cannot be taken for granted. In other words, the foundational premise of a concept-based approach is that there is no one-to-one correspondence between atomic elements of knowledge and atomic elements of linguistic expression. This is why a methodological approach to Terminology merely based upon specialized text research is regarded as biased (Costa, 2013. As a consequence, we argue that interactional strategies between terminologist and domain expert deserve particular research attention. To our mind, the key to concept-based terminological work is to carry out a concept analysis of data gathered from a specialised text corpora combined with an elicitation process of the tacit knowledge and concept-oriented discursive negotiation. Following such view, we put forward a methodology to answer the question: how is blended learning defined in the Post-Bologna scenario? Even though there are numerous high-quality models and practical descriptions for its implementation (similarly to other concepts related to distance learning, the need to understand, demarcate and harmonize the concept of blended learning against the current Higher Education background results from the premise that

    To analyze the relationship between self-concept, aerobic capacity and weight status in schoolchildren. Relational descriptive design in which was assessed the weight status and aerobic capacity of 256 schoolchildren among 8-11 years. Aerobic capacity (low vs high) and the body mass index (normal-weight vs overweight-obesity) were categorized using standard criteria. The self-concept was assessed through the Piers Harris self-concept scale for children. Schoolchildren with normal-weight and high fitness level showed better levels of conductual self-concept (P=.030), physical (Pself-concept (P=.002). The schoolchildren with normal-weight show higher levels of conductual self-concpt (P=.016), intellectual (P=.050), physical (Pself-concept (P=.001). The schoolchildren with a higher fitness level showed better conductual self-concept (P=.024), physical (P=.004), lack of anxiety (P=.011), social (P=.024), and global (P=.003). The results of the study strengthen the importance to transmit to the educative community the knowledge of the relationship between the variables analyzed aiming to improve the schoolchildren self-concept.

    1998-05-01

    Full Text Available The research task described herein aims at the structuring of an analytical tool that traces the time course of geophysical phenomena, regional or global, and compares it to the course of long-term solar conditions, long-term meaning decades or a few centuries. The model is based on the premise that since in a last analysis the preponderance of atmospheric, hydrospheric, and, possibly, some aspects of geospheric phenomena are, or have been, powered by energy issuing from the sun - either now or in the past - the long-term behavior of such phenomena is ultimately "connected" to long-term changes occurring in the sun itself. Accordingly, the proposed research firstly derives and models a stable surrogate pattern for the long-term solar activity, secondly introduces a transfer-function algorithm for modeling the connection between the surrogate and terrestrial phenomena viewed as partners in the connection, and thirdly probes the connection outcome for episodic or unanticipated effects that may arise due to the fact that in the present context, the connection, should it exist, is very likely nonlinear. Part I of the study presents the theory of the concept, while Part II demonstrates the concept's pertinence to a number of terrestrial phenomena.Key words. Solar activity · Kolmogorov algorithm

Analysed the contribution to the development of research hegemony in international relations, which has made the school world-system analysis. According to its founder F. Braudel, the hegemony of the world is a manifestation of inequality, the latter reveals the structural realities that are approved very slowly, very slowly disappear. The concept of a follower of Fernand Braudel, Emmanuel Wallerstein, according to which the hegemony reflects the ability of a particular state to make one part of the international system to its customers, and the second - to drive into a defensive position. The development of the «modern world-system» is defined by Wallerstein changes hegemony. Wallerstein argues that the State has the ability to create a stable geopolitical system of unequal social division of powers, which are part of the normal functioning of the capitalist world-economy. It is also noted that the pattern of ups and downs of world leaders - hegemony - are considered in the research of many scientists, including George Modelski. He develops a theory about hundred-year cycle of global leadership, using the term «selection» to describe the process of competition and the adoption of this role. Among the concepts of hegemony also highlighted the Charles Krauthammer’s conception of monopolarity, on which the present geopolitical structure of the world after the «cold war» - one pole of world power , consisting of the United States as the top of the industrial West. Analyzed the  Piter Taylor’s conception of global hegemony, which distinguishes the competitive and non-competitive era, successive, and the Nail Ferguson’s conception of imperialism. The paper shows that the problem of hegemony in the 70-th years passed from the purely theoretical plane into practical politics

    Body weight status has been linked to other health parameters. The aim of this study was to evaluate the relationship between body weight status and self-concept in a sample of 216 students (9.26 ± 1.26 years) from schools of the Southeast of Spain. BMI (Body-mass index) was used to evaluate the body weight status. Subjects were classified into normal weight, overweight and obesity according to international standards. The six dimensions of self-concept (intellectual, behavioral, physical, lack of anxiety, social and life satisfaction) were assessed using the Piers-Harris Self-Concept Scale. The results showed significant associations between BMI and intellectual self-concept, life satisfaction, global self-concept and physical self. Subjects categorized as overweight or obese were those who showed lower scores on the self-concept scale. Interventions focused on improving the body weight status are needed in order to achieve better self-concept levels and health among young people. Copyright AULA MEDICA EDICIONES 2014.

    The GALEN representation and integration language (GRAIL) has been developed to support effective clinical user interfaces and extensible re-usable models of medical terminology. It has been used successfully to develop the prototype GALEN common reference (CORE) model for medical terminology and for a series of projects in clinical user interfaces within the GALEN and PEN&PAD projects. GRAIL is a description logic or frame language with novel features to support part-whole and other transitive relations and to support the GALEN modelling style aimed at re-use and application independence. GRAIL began as an experimental language. However, it has clarified many requirements for an effective knowledge representation language for clinical concepts. It still has numerous limitations despite its practical successes. The GRAIL experience is expected to form the basis for future languages which meet the same requirements but have greater expressiveness and more soundly based semantics. This paper provides a description and motivation for the GRAIL language and gives examples of the modelling paradigm which it supports.

    The space program is aiming towards the permanent use of space; to build and establish an orbital space station, a Moon base and depart to Mars and beyond. We must look after the total independency from the Earth's natural resources and work in the design of a modular space base in which each module is capable of duplicating one natural process, and that all these modules in combination take us to conceive a space base capable of sustaining life. Every area of human knowledge must be involved. This modular concept will let us see other space goals as extensions of the primary project. The basic technology has to be defined, then relatively minor adjustments will let us reach new objectives such as a first approach for a lunar base and for a Mars manned mission. This concept aims towards an open technology in which standards and recommendations will be created to assemble huge space bases and spaceships from specific modules that perform certain functions, that in combination will let us reach the status of permanent use and exploration of space.

    The importance of content validity in developing patient reported outcomes (PRO) instruments is stressed by both the US Food and Drug Administration and the European Medicines Agency. Content validity is the extent to which an instrument measures the important aspects of concepts that developers or users purport it to assess. A PRO instrument measures the concepts most significant and relevant to a patient's condition and its treatment. For PRO instruments, items and domains as reflected in the scores of an instrument should be important to the target population and comprehensive with respect to patient concerns. Documentation of target population input in item generation, as well as evaluation of patient understanding through cognitive interviewing, can provide the evidence for content validity. Developing content for, and assessing respondent understanding of, newly developed PRO instruments for medical product evaluation will be discussed in this two-part ISPOR PRO Good Research Practices Task Force Report. Topics include the methods for generating items, documenting item development, coding of qualitative data from item generation, cognitive interviewing, and tracking item development through the various stages of research and preparing this tracking for submission to regulatory agencies. Part 1 covers elicitation of key concepts using qualitative focus groups and/or interviews to inform content and structure of a new PRO instrument. Part 2 covers the instrument development process, the assessment of patient understanding of the draft instrument using cognitive interviews and steps for instrument revision. The two parts are meant to be read together. They are intended to offer suggestions for good practices in planning, executing, and documenting qualitative studies that are used to support the content validity of PRO instruments to be used in medical product evaluation.

    Evidence suggests that physical self-concept is associated with physical activity in children and adolescents, but no systematic review of this literature has been conducted. The primary aim of this systematic review and meta-analysis was to determine the strength of associations between physical activity and physical self-concept (general and sub-domains) in children and adolescents. The secondary aim was to examine potential moderators of the association between physical activity and physical self-concept. A systematic search of six electronic databases (MEDLINE, CINAHL, SPORTDiscus, ERIC, Web of Science and Scopus) with no date restrictions was conducted. Random effects meta-analyses with correction for measurement were employed. The associations between physical activity and general physical self-concept and sub-domains were explored. A risk of bias assessment was conducted by two reviewers. The search identified 64 studies to be included in the meta-analysis. Thirty-three studies addressed multiple outcomes of general physical self-concept: 28 studies examined general physical self-concept, 59 examined perceived competence, 25 examined perceived fitness, and 55 examined perceived appearance. Perceived competence was most strongly associated with physical activity (r = 0.30, 95% CI 0.24-0.35, p self-concept (r = 0.25, 95% CI 0.16-0.34, p self-concept (p self-concept and its various sub-domains in children and adolescents. Age and sex are key moderators of the association between physical activity and physical self-concept.

    This article is a report of an analysis of the concept of dying with dignity. Dignity is an important component of providing care for dying patients and their families. Nevertheless, given that this concept is poorly defined, concept analysis is one of the best ways to define and clarify the concept of death with dignity with the aim to enhance its application in clinical practice, research and education. A search of multiple nursing and social sciences databases was undertaken, including Academic Search Complete, Science Direct, ProQuest, Scopus, Medline, PubMed, EBSCO, Ovid, Noormage, Cinahl, Magiran, PsycINFO and SID. After an extensive review of the literature from 1998-2014, about 14 related articles were included in the study. Based on these articles, the applications, attributes and experimental results of and references to death with dignity were recorded. Based on this analysis, the most important attributes of this concept included respect for privacy, respect, spiritual peace and hope. The antecedents of this concept included consideration of moral values during caregiving, preservation of human dignity as a patient right and professional ethics, and belief in the dignity of self and others, consideration of culture in providing end-of-life care. The consequences of this concept included a sense of peace in the patient and their family, peaceful death and provision of patient privacy and comfort. The concept of patient dignity has been referred to in many contexts. However, considering the dignity of dying patients commensurate with their culture is the most important component of care provided by nurses to facilitate a peaceful death. Respecting the dignity of the patient results in the reduction of her/his suffering and prepares her/him for a comfortable death. © 2016 John Wiley & Sons Ltd.

    Full Text Available The active publics issue and the question of the construction of publics are relatively recent in communication studies. After an initial period, when mass communication was seen as aiming at a holistic public, massified and passive and, thus, supposedly influenced via "targeted" messages, now the views on what "publics" mean is becoming diversified and nuanced under the influence of literary theories, cultural studies and what was later called "reception studies". Thus, from the "mass public" we got to the concept of "publics". However, in some recent studies, the mere existence of these publics is being questioned.In this paper, we detail the history of theories on the "public" - from the perspective of the public-as-spectator which later became public-as-audience and public-as-actor - and we set ourselves to show how, from theories on the re-active publics, we arrived, through the transformation of television and the emergence of the new IT&C, to the concept of publics as pro-active as a result of media efforts to build this activism.

    2017-01-31

    This is the final technical report for the AIMES project. Many important advances in science and engineering are due to large-scale distributed computing. Notwithstanding this reliance, we are still learning how to design and deploy large-scale production Distributed Computing Infrastructures (DCI). This is evidenced by missing design principles for DCI, and an absence of generally acceptable and usable distributed computing abstractions. The AIMES project was conceived against this backdrop, following on the heels of a comprehensive survey of scientific distributed applications. AIMES laid the foundations to address the tripartite challenge of dynamic resource management, integrating information, and portable and interoperable distributed applications. Four abstractions were defined and implemented: skeleton, resource bundle, pilot, and execution strategy. The four abstractions were implemented into software modules and then aggregated into the AIMES middleware. This middleware successfully integrates information across the application layer (skeletons) and resource layer (Bundles), derives a suitable execution strategy for the given skeleton and enacts its execution by means of pilots on one or more resources, depending on the application requirements, and resource availabilities and capabilities.

    There is evidence that poor readers are at increased risk for various types of low self-concept-particularly academic self-concept. However, this evidence ignores the heterogeneous nature of poor readers, and hence the likelihood that not all poor readers have low self-concept. The aim of this study was to better understand which types of poor readers have low self-concept. We tested 77 children with poor reading for their age for four types of self-concept, four types of reading, three types of spoken language, and two types of attention. We found that poor readers with poor attention had low academic self-concept, while poor readers with poor spoken language had low general self-concept in addition to low academic self-concept. In contrast, poor readers with typical spoken language and attention did not have low self-concept of any type. We also discovered that academic self-concept was reliably associated with reading and receptive spoken vocabulary, and that general self-concept was reliably associated with spoken vocabulary. These outcomes suggest that poor readers with multiple impairments in reading, language, and attention are at higher risk for low academic and general self-concept, and hence need to be assessed for self-concept in clinical practice. Our results also highlight the need for further investigation into the heterogeneous nature of self-concept in poor readers.

    Asteroid mining as such is not a new concept, as it has been described in science fiction for more than a century and some of its aspects have been studied by academia for more than 30 years. Recently, there is a renewed interest in this subject due the more and more concrete plans for long-duration space missions and the need for resources to support industrial activity in space. The use of locally available resources would greatly improve the economics and sustainability of such missions. Due to its economy in material, use of additive manufacturing (AM) provides an interesting route to valorize these resources for the production of spare parts, tools and large-scale structures optimized for their local microgravity environment. Proof of concept has already been provided for AM of moon regolith. In this paper the concept of In-Situ Resource Utilization is extended towards the production of metallic objects using powdered iron meteorite as raw material. The meteorite-based powder was used to produce a structural part but further research is needed to obtain a high density part without microcracks.

    Full Text Available Various theories have attempted to explain the mechanisms of learning, for its part, cognitivism have integrated mental structures in these mechanisms. Recent didactic research has revealed the role of conceptions of cultural background can "promote" or "oppose" the acquisition and ownership of new knowledge by the learner. Today and in the multitude of information sources and mode of disciplinary learning and compartmentalized knowledge acquisition has become complex. The teaching learning process is facing a major problem: how a teacher can be taken into account conceptions of learners in teaching practices? How to help learners to "overcome" their conceptions? Within which limits it is itself influenced by his conceptions in educational choices? What teaching strategy can cope with the complexity of learning in our society today? The analysis of the conceptions of teachers about the complexity of the ecosystem and pedagogical choices can bring out the modes of reasoning underlying the notion of complexity.

    2018-06-01

    Full Text Available The pollution generated by cemeteries and their overload are increasingly worrisome issues in current society, and yet there are few studies seeking to discuss and generate solutions in this field to provide better lives to the population. Thus, this research has aimed to develop a new concept of a cremation service called “Mobile Crematorium”, aiming at innovation and an alternative for reducing impacts caused by cemeteries. Hence, a new model of service development was used, jointly with bibliographic research, semi-structured interviews with entrepreneurs and questionnaires answered by the population to collect essential information. Thus, requirements, needs and specifications of the clients and the service were developed, jointly with an analysis, simulation and selection of alternative solutions generated that allowed the creation of the new concept. Finally, the service process was modelled on the “Service Blueprint”, allowing visualization and identification of possible process failures and improvements thereon.

    Full Text Available The library is an effort to maintain and improve the efficiency and effectiveness of the learning process. Various means have been used to enhance the library's role in community development. One way is to develop a concept and a different orientation in the management system or the library. The concept in question is gamification. Gamification is a process with the aim of changing jobs or activities that usually go tedious and less enjoyable to be more interesting and fun to do. One approach taken is to reward both virtual and non-virtual that can increase people's motivation to do something, in this case, is to visit and take advantage of the functions and library facilities. This research resulted in a model that features a library application with the concept of gamification. The model can be implemented into an application that will increase visits and activities at the library. Thus the function and the main purpose of the library be met..

    2000-12-01

    The aims of the study were to examine differences between boys and girls in global self-esteem and in specific domains of self-concept. Several measures of global self-esteem and multidimensional self-concept were administered to 61 boys and 64 girls. Analysis showed that boys reported higher scores than girls on global self-esteem, measured on the Coopersmith Self-esteem Inventory and the Feelings of Inadequacy Scale by Janis-Field, but this result was not reproduced when self-esteem was measured on the Rosenberg Self-esteem Scale. No differences have been found in domain-specific self-concepts, except for the ethical-moral self-concept, on which girls reported higher scores than boys.

    The charge to Panel 3 was to look at the idea of concept improvements in the context of US DOE management of the magnetic fusion program. The panel suggested that if DOE were commited to the idea of concept improvement, it needed to overcome the existing impression it was not receptive to new ideas. In part the long time scale for development of fusion energy, coupled with the rate of change of scientific programs and research based on emerging knowledge, means that in general the program will be much different ten to twenty years in the future. To be able to meet this changing direction, the US program must maintain an openness to look at promising alternative ideas, spend money on developing the ideas, and consider funding some to intermediate development levels. Stellerator research was offered as one alternative to consider in light of present international work. The panel urged supporting the development of new concepts and ideas, as well as continued support for plasma physics basic research

  2. Space Elevator Concept Considered a Reality

    Science.gov (United States)

    2000-01-01

    The `once upon a time' science fiction concept of a space elevator has been envisioned and studied as a real mass transportation system in the latter part of the 21st century. David Smitherman of NASA's Marshall Space Flight Center's Advanced Projects Office has compiled plans for such an elevator. The space elevator concept is a structure extending from the surface of the Earth to geostationary Earth orbit (GEO) at 35,786 km in altitude. The tower would be approximately 50 km tall with a cable tethered to the top. Its center mass would be at GEO such that the entire structure orbits the Earth in sync with the Earth's rotation maintaining a stationary position over its base attachment at the equator. Electromagnetic vehicles traveling along the cable could serve as a mass transportation system for transporting people, payloads, and power between space and Earth. This illustration by artist Pat Rawling shows the concept of a space elevator as viewed from the geostationary transfer station looking down the length of the elevator towards the Earth.

    2001-01-01

    In the CANDU - advanced passive moderator (APM) concept, the positive void reactivity is eliminated by reducing the density of the moderator. The simple model for the CANDU APM concept consists of the calandria, heat exchanger, pump, and a stabilizing tank, along with connecting piping. The calandria is divided into two parts, one part simulates the down area, while the other simulates up flow area. To demonstrate the thermalhydraulic behavior of the APM concept, Canadian algorithm for thermalhydraulic network analysis (CATHENA) code is used. The simulation for a pressure boundary condition of 300, 330 and 360 kPa and for water coolant mass flow rate boundary conditions of 2000 and 3000 kg/s respectively have been studied. Preliminary results show that there is boiling in the core, with vapor condensing in the heat exchanger. It is important to note, that the solution had not reached steady state when the boiling occurred

    Professional self-concept is a critical driver of job satisfaction. In Australia, as international nursing enrolments rise, nursing is increasingly characterised by a professional body of international nurses who may differ from domestic Australian nurses in their nursing self-concept. At present, little is known about the extent to which domestic and international students nurses' self-concepts may differ. The present study aimed to elucidate and contrast domestic and international nursing students' self-concepts from one large Australian university. A total of 253 domestic (n=218) and international (n=35) undergraduate nursing students from a large public university in Sydney, Australia completed the Nurses' Self-Concept Instrument (NSCI). Multiple-Indicator-Multiple-Indicator-Cause (MIMIC) modelling was used to assess the effects of student group (domestic and international) on the latent self-concept factors of the NSCI. Domestic and international students' professional self-concepts were similarly high. MIMIC modelling demonstrated that domestic students had a higher patient care self-concept in comparison to international students. Results imply that it may be useful for Australian universities to foster strategies that enhance specific domains of self-concepts (e.g., care) which may be underdeveloped for at least some cultural groups within the international nursing student population compared with domestic nursing students.

    Castles, Anne; Kohnen, Saskia; Banales, Erin

    2016-01-01

    There is evidence that poor readers are at increased risk for various types of low self-concept—particularly academic self-concept. However, this evidence ignores the heterogeneous nature of poor readers, and hence the likelihood that not all poor readers have low self-concept. The aim of this study was to better understand which types of poor readers have low self-concept. We tested 77 children with poor reading for their age for four types of self-concept, four types of reading, three types of spoken language, and two types of attention. We found that poor readers with poor attention had low academic self-concept, while poor readers with poor spoken language had low general self-concept in addition to low academic self-concept. In contrast, poor readers with typical spoken language and attention did not have low self-concept of any type. We also discovered that academic self-concept was reliably associated with reading and receptive spoken vocabulary, and that general self-concept was reliably associated with spoken vocabulary. These outcomes suggest that poor readers with multiple impairments in reading, language, and attention are at higher risk for low academic and general self-concept, and hence need to be assessed for self-concept in clinical practice. Our results also highlight the need for further investigation into the heterogeneous nature of self-concept in poor readers. PMID:27867764

    Full Text Available It is generally considered that knowing one language is not enough in this era. People need to learn a second language in addition to their mother tongue to meet the demand of today’s life as many of them are becoming a part of multilingual society as well as to face the globalisation. This paper aims to demonstrate the reasons of people learning a second by looking at the several goals they want to achieve in current situation and link it to the second language learning in education context. Subsequently, it also provides some criticism against the majority of English language teachings that set native speaker’s competence as the ultimate goal and highlights the concept of L2 user as a new paradigm and its implication to second language learning.

  10. [The concept of health and disease].

    Ruíz, R H

    1976-12-01

    1. The author reviews some current concepts concerning the definitions and uses of the concepts of health and illness. Starting from the definitions in Psychiatry, "normality" is considered from the statistic, the normative and the clinical standpoints, and as a part of a continuum stretching from health to illness. Several approaches are analyzed, among which Wittaker's, who sets forth the following indicators of normality: a) self-knowledge; b) self-esteem; c) self-security; d) capacity for giving and receiving affection; e) satisfaction of corporal needs; f) productivity and capacity for happiness; g) lack of tensions and of hipersensitivity. 2. The concept of illness as an operative concept is also analyzed, leading to the following statements: a) it is inexistent in non-biological sciences; b) it appears in social sciences only through extrapolation; c) in medicine it means the breacking of homeosthasis; d) in psychology and dynamic psychiatry it means the abnormal stressing of normal mechanisms, common to all persons. 3. The concept of health as equilibrium is also analyzed, with the following precisions: a) equilibrium is defined within a system as affecting the whole of it, and implying transformation and self-regulation; b) homeosthasis is a case of equilibrium for steady complex systems; c) adaptation is the maintenance of equilibrium when there are exchanges with the evironment. 4. Finally, those concepts are applied to mental illness and its limits, and the following criteria are set forth: a) amount of anguish; b) depression related to its motives, intensity, persistence and frequency; c) regression to previous development stages; d) use of defense mechanisms in an inadequate or stereotyped way.

    The paper presents the concept of a complex system, aimed to assure the traceability of 222 Rn measurements, from the absolute (primary) standardization to the preparation and delivery of secondary standards, gas vials. The system will contain a solid 226 Ra source, a gas radon circuit, connections with a liquid scintillator vial and with glass vials. The absolute standardization of the 222 Rn, in equilibrium with all the short half life daughters, will be performed by the method of the Liquid Scintillation Counting (LSC). The system, and method, will allow our laboratory to take part in future international 222 Rn comparisons. The transfer of activity unit from the primary to the secondary standardization will be performed by the preparation of vials with 222 Rn gas, comparative measurements by LSC and a GeHP gamma-ray spectrometry system, or a well type NaI(Tl) crystal, and their link. The secondary standards will be used for the calibration of measurement instruments, for assurance of controlled radon atmosphere in 'radon chambers', and for the validation of some calculation models for various detectors efficiency. The range of activities for secondary standards is in agreement with the national measurement necessities. (author)

    Safety pharmacology (SP) is an essential part of the drug development process that aims to identify and predict adverse effects prior to clinical trials. SP studies are described in the International Conference on Harmonisation (ICH) S7A and S7B guidelines. The core battery and supplemental SP studies evaluate effects of a new chemical entity (NCE) at both anticipated therapeutic and supra-therapeutic exposures on major organ systems, including cardiovascular, central nervous, respiratory, renal and gastrointestinal. This review outlines the current practices and emerging concepts in SP studies including frontloading, parallel assessment of core battery studies, use of non-standard species, biomarkers, and combining toxicology and SP assessments. Integration of the newer approaches to routine SP studies may significantly enhance the scope of SP by refining and providing mechanistic insight to potential adverse effects associated with test compounds. - Highlights: • SP — mandatory non-clinical risk assessments performed during drug development. • SP organ system studies ensure the safety of clinical participants in FiH trials. • Frontloading in SP facilitates lead candidate drug selection. • Emerging trends: integrating SP-Toxicological endpoints; combined core battery tests

  15. Space Mission Concept Development Using Concept Maturity Levels

    Science.gov (United States)

    Wessen, Randii R.; Borden, Chester; Ziemer, John; Kwok, Johnny

    2013-01-01

    Over the past five years, pre-project formulation experts at the Jet Propulsion Laboratory (JPL) has developed and implemented a method for measuring and communicating the maturity of space mission concepts. Mission concept development teams use this method, and associated tools, prior to concepts entering their Formulation Phases (Phase A/B). The organizing structure is Concept Maturity Level (CML), which is a classification system for characterizing the various levels of a concept's maturity. The key strength of CMLs is the ability to evolve mission concepts guided by an incremental set of assessment needs. The CML definitions have been expanded into a matrix form to identify the breadth and depth of analysis needed for a concept to reach a specific level of maturity. This matrix enables improved assessment and communication by addressing the fundamental dimensions (e.g., science objectives, mission design, technical risk, project organization, cost, export compliance, etc.) associated with mission concept evolution. JPL's collaborative engineering, dedicated concept development, and proposal teams all use these and other CML-appropriate design tools to advance their mission concept designs. This paper focuses on mission concept's early Pre-Phase A represented by CMLs 1- 4. The scope was limited due to the fact that CMLs 5 and 6 are already well defined based on the requirements documented in specific Announcement of Opportunities (AO) and Concept Study Report (CSR) guidelines, respectively, for competitive missions; and by NASA's Procedural Requirements NPR 7120.5E document for Projects in their Formulation Phase.

  16. Alternative fusion concepts: engineering and utility considerations

    Gough, W.C.; Amherd, N.A.

    1978-01-01

    Alternative systems are described to be an integral part of the total fusion effort, making use of many developments of the mainline efforts but also contributing on a broad scale to improved understanding of fusion plasmas, technology and engineering. We hypothesize that the rationale for supporting alternative concepts will shift from physics related justifications to the perceived benefits for commercial use. Three principal factors are used to describe the commercialization potential of energy systems: technological risk, perceived benefit, and capital requirements. R and D can reduce the risk of a technology option, but perceived benefit and capital availability are largely governed by non-R and D elements. Hence, power station decision criteria as determined by electric-utility executives are presented, and a balance among the three commercialization factors described. An outline of past and on-going alternative concept reactor study endeavors is given and a suggestion for rapidly developing the physics base of the concepts is described

    Although knowledge translation is one of the most widely used concepts in health and medical literature, there is a sense of ambiguity and confusion over its definition. The aim of this paper is to clarify the characteristics of KT. This will assist the theoretical development of it and shape its implementation into the health care system Methods: Walker and Avant's framework was used to analyze the concept and the related literature published between 2000 and 2010 was reviewed. A total of 112 papers were analyzed. Review of the literature showed that "KT is a process" and "implementing refined knowledge into a participatory context through a set of challenging activities" are the characteristics of KT. Moreover, to occur successfully, KT needs some necessary antecedents like an integrated source of knowledge, a receptive context, and preparedness. The main consequence of successful process is a change in four fields of healthcare, i.e. quality of patient care, professional practice, health system, and community. In addition, this study revealed some empirical referents which are helpful to evaluate the process. By aiming to portray a clear picture of KT, we highlighted its attributes, antecedents, consequences and empirical referents. Identifying the characteristics of this concept may resolve the existing ambiguities in its definition and boundaries thereby facilitate distinction from similar concepts. In addition, these findings can be used as a knowledge infrastructure for developing the KT-related models, theories, or tools.

    2017-04-01

    Although the concept of 'Transforming care' is promising for improving health care, there is no consensus in the field as to its definition. The aim of this concept analysis is to develop a deeper understanding of the term 'Transforming care' within the nursing discipline, in order to facilitate its comprehension, implementation, and evaluation. We performed a comprehensive literature review on electronic databases such as Medline (PubMed), Cinahl (Ebsco), Cochrane Library, PsycINFO (Ovid), Web of Science, Wiley-Blackwell, ScienceDirect, and SpringerLink and used Walker and Avant's approach to analyse the concept. From the 20 studies selected for this analysis, 3 main attributes of 'Transforming care' were identified: patient-centredness, evidence-based change, and transformational leadership driven. We suggest an operational definition to facilitate the implementation of the concept in practice. Furthermore, we propose that implementation is guided by the following key ideas: (1) fostering a culture of continuous improvement; (2) encouraging bottom-up initiatives; (3) promoting patient-centred care; and (4) using transformational leadership. Lastly, the evaluation of 'Transforming care' initiatives should assess care processes and professionals' and patients' outcomes.

  4. The Concept of Love in Dostoyevsky's White Nights

    2015-07-01

    Full Text Available Love is a phenomenon we are involved with in our life. The concept of love has been immensely discussed and challenged by philosophers and psychologists all throughout the history because of its salient and effective role in our individual and social lives. Self-love and altruistic love, two main types of love, have been repeatedly reflected in psychologists' works; self-love refers to a kind of love which is based on psychological egoism; on the other hand, altruistic love is conceived of as a sort of love which is principally based on selflessness, caring, respect, and sacrifice. “White Nights” is a short story by Fyodor Dostoyevsky which seemingly has an altruistic view toward love; it sounds that Dostoyevsky has made a purposeful attempt to praise such altruistic love in the story. Thus, it has been tried to delve into the concept of love manifested in White Nights. This paper is divided into two parts; in the first part, a theoretical framework entailing definitions of love and its types is depicted; in the second part, an account of how love is emerged in the story will be explained. At last, this paper substantiates that altruistic love is represented and admired in this story and is preferred to the other types of love.

    A higher degree of ecological safety in ship traffic depends on onboard measures as well as reception facilities on shore, treatment of ship generated wastes and preparedness for combating emergency oil spills. The problem is particularly acute in the North Sea Route (NSR) due to high vulnerability of the Arctic ecosystems, low rates of natural degradation of oil, absence of forward coastal infrastructure, low efficiency of oil combating means in ice conditions and severe climatic conditions. Oil spills in the NSR are likely to occur as the offshore production and transportation of oil increase. Therefore a regional Oil Spill Contingency Plan (OSCP) is being constructed and developed on 3 levels: 1) Development of concept, definition of response organisations and their technical ability (Part I). 2) Collection and analysis of information, development of scenarios of probable oil spills, clearing of the funding mechanism and basis for additional outside co-operation from other Russian regions and circumpolar countries (part II). 3) Development of NSR OSCP (part III). The present report (part I) provides the plan concept, rescue organisations and data on types and amounts of the oil spill combating technical means and of the floating facilities available in the NSR or it`s vicinity. The concept takes into account subdivision of the Route, interaction and links between responsible organisations, realities of the Russian Arctic such as transport, communications, energy, labour resources etc. and requirements of the IMO and of the International Convention OPRC 90. According to Russian legislation implementation of combating operations at sea is the responsibility of the Maritime Pollution Control and Salvage Administration that consists of a Central Administration and basin emergency divisions situated in Murmansk and Nahodka. The body is responsible for carrying out cleaning operations at sea from installations and may be assisted by resources and means of the co

    To explore the concept of home and its' expressed spatialities in current palliative care research. Home is a central environment for living, caring, and dying. However, pure investigations of the sets of ideas linked to the concept seemed missing. Although identified as an important location, spatial perspectives expressed through the concept of home appeared unexplored. Rodgers' evolutionary concept analysis. Scientific articles published between January 2009 and September 2015. Rodgers' evolutionary concept analysis. Resulting attributes were explored from two geographically informed spatial perspectives. As main results, six attributes were identified and explored: Home as actor-capable of acting; emotional environment-something people have feelings for; place-a part of personal identity and a location; space-complex and relational spatial connections and a site for care; setting-passive background and absolute space; becoming-a fluid spatiality constantly folded. Examples of attributes and suggestions for further concept development were identified. The concept reflects various sets of ideas as well as expressing both relational and absolute perspectives of space. The most challenging for nursing research and practice seems to be investigation, operationalization, and testing the implementation of sets of ideas reflecting a relational thinking of space. © 2018 Wiley Periodicals, Inc.

    2006-01-01

    SKB and Posiva are performing an R and D programme over the period of 2002-2007 with the overall aim to find out whether the KBS-3H concept can be regarded as an alternative to the KBS-3V concept for disposal of spent nuclear fuel. A feasibility study of the KBS-3H concept was carried out in 2002, followed by the setting up of basic design in 2003, and since 2004 the demonstration phase is ongoing, ending with the evaluation of the potencial of the concept in 2007. In order to find out whether the concept can be regarded as a viable alternative to the KBS-3V concept demonstration and design work involve development of excavation technology of the drift, detailed studies on the function of the buffer bentonite, deposition equipment and methods for construction of low-pH shotcrete plugs. The investigations related to long-term safety are based on difference analyses between KBS-3V and KBS-3H and focus on KBS-3H specific processes. By the end of 2007 the KBS-3H concept will be reported including a preliminary safety case of the concept with Olkiluoto in Finland as a reference site. (author)

    Brite, Roberta; Nunes, Francisco; Souza, Danielle

    2015-01-01

    This study aims to analyze the managers' conceptions involved in the process of labor inclusion in 18 supermarkets with 5,000 employees, 300 of whom with disabilities. A group of 90 managers working with people with disability completed a Conceptions of Disability Inventory (CDI) about their conceptions of people with disabilities. Their responses were categorized as follows: (a) disability as a spiritual manifestation; b) disability as a deviation from normality; (c) disability based on assumptions of inclusion; (d) disability assessed from performance criteria; (e) disability assessed from the connection established with the work organization; (f) disability conceived by contracting benefits, and (g) disability based on the perception of the need for training. Based on the outcomes of the Pearson Correlation Matrix, significant linear correlations were found in seven managers' conceptions of disability. The results also indicate that the managers' conceptions contributed to differentiated inclusionist actions based on their perceptions related to people with disabilities. This study data contributes to identifying the best practices in labor inclusion. The outcomes of the present study could lead to development of a public policy aimed towards humanizing job alternatives for people with disability.

    This paper is the first part of the study on the development of a smart active layer (SAL) sensor, which consists of two parts. In this first part, the theory and concept of the SAL sensor is investigated, which is designed for the detection of elastic waves caused by internal cracks and damages in structures. For the development SAL sensor, (i) the basic theory of elastic waves was studied, (ii) the feasible study of the SAL as an elastic waves detection sensor using the finite element analysis (FEA) with respect to a piezoceramic disc was performed. (iii) the comparison of performances between some piezoceramic sensors and a commercial acoustic emission (AE) sensor was accomplished to ensure the applicability by the experimental means, such as a pencil lead break test. Also, the conceptional study for the SAL sensor, which can be utilized for the effective detection and locating of defects by the arrangement of regularly distributed sensors, was discussed

  17. Reflections on the value concept in accounting

    Directory of Open Access Journals (Sweden)

    P. Buys

    2009-07-01

    Full Text Available The recent meltdown in global finances and the reasons for it may make people doubtful about the stewardship function of accounting. In the global financial markets, there is a great fascination with the reality that accounting values intend to reflect. However, what many people considered valuable is now suddenly of no value. The question can therefore be asked what is meant by the value concept as a foundation to modern-day accountancy. “Value” is a concept that is open to different interpretations, based on the needs, perspectives and personal values of the interpreter. This article aims to reflect on the value concept from an accounting perspective in analysing the fundamental quali-tative perspectives and how these perspectives might affect the quantitative value measurements, as reported in the financial statements. From a quantitative perspective, accounttancy aims to measure and report the monetary values of items. However, there is a move towards a mixed valuation model with many financial statements, including both historical cost and value-based accounting information. The article concludes that this questionable development opens up many additional and subjective interpretations of accounting value measurement and reporting. Both valuation measurement methods have merit when considered in the overall purpose of accounting information. However, subjective value-based mea-surements may cast a shadow of doubt on the reliability and comparability requirements of accounting value information.

  18. Exploring international gender differences in mathematics self-concept

    Goldman, Amy D.; Penner, Andrew M.

    2013-01-01

    This study provides an international perspective on mathematics by examnnng mathematics self-concept, achievement, and the desire to enter a career involving mathematics among eighth graders in 49 countries. Using data from the Trends in International Mathematics and Science Study, this study shows that self-concept in mathematics is more closely related to the desire to enter a career using mathematics than achievement is. Further, while gender differences in mathematics self-concept are smaller in more egalitarian countries, both girls and boys have lower mathematics self-concepts and less interest in mathematics careers in these countries. These findings reveal a policy paradox: policies aimed at training the next generation of STEM professionals often highlight the need to close the gender gap, but countries with smaller gender gaps have fewer boys and girls interested in mathematics-intensive careers. We conclude by highlighting the importance of disentangling instrumental and expressive aspects of gender inequality in STEM fields. PMID:27840545

  3. An ontology-based exploration of the concepts and relationships in the activities and participation component of the international classification of functioning, disability and health.

    2012-02-28

    The International Classification of Functioning, Disability and Health (ICF) is a classification of health and health-related issues, aimed at describing and measuring health and disability at both individual and population levels. Here we discuss a preliminary qualitative and quantitative analysis of the relationships used in the Activities and Participation component of ICF, and a preliminary mapping to SUMO (Suggested Upper Merged Ontology) concepts. The aim of the analysis is to identify potential logical problems within this component of ICF, and to understand whether activities and participation might be defined more formally than in the current version of ICF. In the relationship analysis, we used four predicates among those available in SUMO for processes (Patient, Instrument, Agent, and subProcess). While at the top level subsumption was used in most cases (90%), at the lower levels the percentage of other relationships rose to 41%. Chapters were heterogeneous in the relationships used and some of the leaves of the tree seemed to represent properties or parts of the parent concept rather than subclasses. Mapping of ICF to SUMO proved partially feasible, with the activity concepts being mapped mostly (but not totally) under the IntentionalProcess concept in SUMO. On the other hand, the participation concept has not been mapped to any upper level concept. Our analysis of the relationships within ICF revealed issues related to confusion between classes and their properties, incorrect classifications, and overemphasis on subsumption, confirming what already observed by other researchers. However, it also suggested some properties for Activities that could be included in a more formal model: number of agents involved, the instrument used to carry out the activity, the object of the activity, complexity of the task, and an enumeration of relevant subtasks.

    2010-12-01

    data to groundwater models but these models are only aimed at solving one specific part of the earth’s system, e.g. the flow of groundwater to an abstraction borehole or the availability of water for irrigation. Particular problems arise when model data from two or more disciplines are incompatible in terms of data formats, scientific concepts or language. Other barriers include the cultural segregation within and between science disciplines as well as impediments to data exchange due to ownership and copyright restrictions. OpenMI and GeoSciML are initiatives that are trying to overcome these barriers by building international communities that share vocabularies and data formats. This paper gives examples of the successful merging of geological and hydrological models from the UK and will introduce the vision of an open Environmental Modelling Platform which aims to link data, knowledge and concepts seamlessly to numerical process models. Last but not least there is an urgent need to create a Subsurface Information System akin to a Geographic Information System in which all results of subsurface modelling can be visualised and analysed in an integrated manner and thereby become useful for decision makers.

    2013-08-01

    To present the operationalization of concepts in the nursing intellectual capital theory and the results of a methodological study aimed at empirically validating the concepts. The nursing intellectual capital theory proposes that the stocks of nursing knowledge in an organization are embedded in two concepts, nursing human capital and nursing structural capital. The theory also proposes that two concepts in the work environment, nurse staffing and employer support for nursing continuing professional development, influence nursing human capital. A cross-sectional design. A systematic three-step process was used to operationalize the concepts of the theory. In 2008, data were collected for 147 inpatient units from administrative departments and unit managers in 6 Canadian hospitals. Exploratory factor analyses were conducted to determine if the indicator variables accurately reflect their respective concepts. The proposed indicator variables collectively measured the nurse staffing concept. Three indicators were retained to construct nursing human capital: clinical expertise and experience concept. The nursing structural capital and employer support for nursing continuing professional development concepts were not validated empirically. The nurse staffing and the nursing human capital: clinical expertise and experience concepts will be brought forward for further model testing. Refinement for some of the indicator variables of the concepts is indicated. Additional research is required with different sources of data to confirm the findings. © 2012 Blackwell Publishing Ltd.

    Taylor, Tonya N; Mantell, Joanne E; Nywagi, Ntobeko; Cishe, Nomazizi; Cooper, Diane

    2013-01-01

    This paper explores notions of fatherhood and their linkages to fertility desires and intentions among a treatment-naïve cohort of Xhosa-speaking male key informants living with HIV, aged 20-53 in Cape Town, South Africa. Analysis is based on an initial 27, and 20 follow-up, interviews with men who were part of a study that assessed the acceptability of safer conception and alternative parenting strategies among men and women newly diagnosed with HIV to inform an intervention. Grounded theory analysis revealed themes related to the cultural imperative of biologically-connected fatherhood. Certain safer-conception strategies aimed at minimising the risk of HIV transmission were perceived as threats to paternity. These findings suggest that understanding of social and cultural beliefs related to notions of paternity and fatherhood may inform the implementation of acceptable safer-conception options for HIV-positive men and their infected and uninfected female partners in a high-HIV prevalence, low-resource setting.

    Over the past several years, numerous design concepts have been developed to enhance the ability of containments to withstand severe reactor accidents. As part of the AIF sponsored IDCOR program, a study has been completed to survey and evaluate these alternate containment design concepts. The study defines the minimum as well as optimum functional and design criteria which any such system must meet. Six concepts which satisfy these criteria are then evaluated based upon factors such as: risk reduction potential, cost, constructability and the potential detrimental effects. Based upon the results of these evaluations, a ranking of the design concepts is developed. The purpose of this paper is to present the results of the IDCOR sponsored study

  16. 'SIMPLE' - a novel concept of an imaging camera for space applications

    International Nuclear Information System (INIS)

    Ferenc, Daniel

    2003-01-01

    A novel concept of a large camera for space applications is proposed. It comprises extremely light and inexpensive construction, and very high photon detection efficiency. The essential point of the concept is the evasion of any vacuum-sealing constructional elements, and the exploitation of vacuum in space. This concept was developed particularly for the next-generation experiments aimed to detect extensive air showers in the atmosphere, initiated by extreme energy cosmic rays (like the EUSO experiment). The SIMPLE camera, as well as its launch, should be much less expensive than the previously considered options

  17. On the concept of individual in ecology and evolution.

    Science.gov (United States)

    Metz, J A J

    2013-03-01

    Part of the art of theory building is to construct effective basic concepts, with a large reach and yet powerful as tools for getting at conclusions. The most basic concept of population biology is that of individual. An appropriately reengineered form of this concept has become the basis for the theories of structured populations and adaptive dynamics. By appropriately delimiting individuals, followed by defining their states as well as their environment, it become possible to construct the general population equations that were introduced and studied by Odo Diekmann and his collaborators. In this essay I argue for taking the properties that led to these successes as the defining characteristics of the concept of individual, delegating the properties classically invoked by philosophers to the secondary role of possible empirical indicators for the presence of those characteristics. The essay starts with putting in place as rule for effective concept engineering that one should go for relations that can be used as basis for deductive structure building rather than for perceived ontological essence. By analysing how we want to use it in the mathematical arguments I then build up a concept of individual, first for use in population dynamical considerations and then for use in evolutionary ones. These two concepts do not coincide, and neither do they on all occasions agree with common intuition-based usage.

  4. Adolescent self-concept among Han, Mongolian, and Korean Chinese.

    Sharpes, D K; Wang, X

    1997-01-01

    Studies of self-concept have suffered from a lack of both a solid theoretical base and a clear definition of the term. It is not clear whether self-concept is a construct from the cognitive sciences, an active part of personality or of the ego and unconscious, or a physiological process as indicated from neurological research. Nor is it clear whether the psychological construct of self is related to other concepts, such as personal identity, self-esteem, and the ego, as sometimes these refer to the whole person or a structure or element within a person. What is evident is that the majority of researchers continue to assume that self-concept, however defined in theory, is primarily governed by environmental determinants despite abundant evidence from the neurosciences of the strong influence of its genetic heritability. This study assumed a genetic hypothesis, that self-concept is developmental and that adolescent perception of personal, relational, and academic self-identity occurs uniformly across cultures and environmental circumstances. Data were collected using a validated survey instrument, translated into Chinese, from majority and minority adolescents in the People's Republic of China. High similarity was found between the majority and minority adolescents, suggesting developmental propensities in the formation of self-concept.

    Thye, Johannes; Straede, Matthias-Christopher; Liebe, Jan-David; Hübner, Ursula

    2014-01-01

    Due to the emerging evidence of health IT as opportunity and risk for clinical workflows, health IT must undergo a continuous measurement of its efficacy and efficiency. IT-benchmarks are a proven means for providing this information. The aim of this study was to enhance the methodology of an existing benchmarking procedure by including, in particular, new indicators of clinical workflows and by proposing new types of visualisation. Drawing on the concept of information logistics, we propose four workflow descriptors that were applied to four clinical processes. General and specific indicators were derived from these descriptors and processes. 199 chief information officers (CIOs) took part in the benchmarking. These hospitals were assigned to reference groups of a similar size and ownership from a total of 259 hospitals. Stepwise and comprehensive feedback was given to the CIOs. Most participants who evaluated the benchmark rated the procedure as very good, good, or rather good (98.4%). Benchmark information was used by CIOs for getting a general overview, advancing IT, preparing negotiations with board members, and arguing for a new IT project.

  6. SCWR Concept in Korea

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2014-08-15

    One of the major difficulties in the design of an SCWR is the additional neutron moderation in order to compensate the low coolant density in the later stage of coolant heat-up. The water rod concept was introduced as a simple method to provide additional moderation, however it may result in an inevitable complexity in the design of the reactor upper part. A solid moderator concept was introduced in the Korean SCWR to avoid this difficulty. A conceptual design of a 1400 MWe SCWR core with a cruciform type of U/ZrH{sub 2} solid moderator has been studied. The design features include a solid moderator design, an axial zoning of the burnable poison and fuel rod, a flow rate control by adjusting the orifice design, and a control rod design for an excess reactivity control. The maximum power peaking is 2.48 and the maximum coolant temperature is 577°C. Reactivity coefficients such as the moderator temperature coefficient and fuel temperature coefficient are negative for the whole burn-up period. At a cold zero power condition, the minimum shutdown margin is 1.16%Δρ at the beginning of a cycle, which satisfies the required shutdown margin limit. The concept described here should not be considered as a complete one, but a preliminary idea. It is solely based on information frozen at the time, and is subject to further improvement.

  8. Interdisciplinary Approaches at Institutions of Higher Education: Teaching Information Systems Concepts to Students of Non-Computer Science Programs

    Directory of Open Access Journals (Sweden)

    Roland Schwald

    2011-07-01

    Full Text Available The aim of this paper is to present a curriculum development concept for teaching information systems content to students enrolled in non-computer science programs by presenting examples from the Business Administration programs at Albstadt-Sigmaringen University, a state university located in Southern Germany. The main focus of this paper therefore is to describe this curriculum development concept. Since this concept involves two disciplines, i.e. business administration and computer science, the author argues that it is necessary to define the roles of one discipline for the other and gives an example on how this could be done. The paper acknowledges that the starting point for the development of a curriculum such as one for a business administration program will be the requirements of the potential employers of the graduates. The paper continues to recommend the assignment of categorized skills and qualifications, such as knowledge, social, methodological, and decision making skills to the different parts of the curricula in question for the development of such a curriculum concept. After the mapping of skills and courses the paper describes how specific information systems can be used in courses, especially those with a specific focus on methodological skills. Two examples from Albstadt-Sigma-ringen University are being given. At the end of the paper the author explains the implications and limitations of such a concept, especially for programs that build on each other, as is the case for some Bachelor and Master programs. The paper concludes that though some elements of this concept are transferable, it is still necessary that every institution of higher education has to take into consideration its own situation to develop curricula concepts. It provides recommendations what issues every institution should solve for itself.

    This research aims to describe the profile of the students’ conception and perception on the simple electrical circuit. The results of this research suppose to be used as a reference by teachers to use learning models or strategies to improve understanding the physics concept. The research method used is descriptive qualitative. Research subjects are the students of physics education program, Universitas Sebelas Maret, Surakarta, Indonesia (49 students). The results showed that students have alternative conceptions. Their conceptions are (1) a high-voltage wire has an electric current and can cause electric shock, (2) the potential difference and the value of resistance used in a circuit is influenced by electric current, (3) the value of resistance of a lamp is proportional to the filament thickness, (4) the amount of electric current that coming out from the positive pole battery is the same for all type of circuit, in series or parallel (battery is constant current sources), (5) the current at any resistor in the series circuit is influenced by the resistor used, (6) the resistor consume the current through it. This incorrect conception can cause misconceptions.

  12. CONSIDERATIONS REGARDING THE 21st CENTURY’s HIGH QUALITY SECURITY CONCEPT

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available The present paper is devoted to qualitative security which today has to become a topic issue of world security. The opinions regarding the 21st century’s security concept are contradictory since people have different understandings and perceptions of security, respectively insecurity, and do not agree to analyze the security concept as a function of the system. Our take is that implementation of some new security concepts should aim an analysis and understanding of security in an integrating view, in order to make the most comprehensive security environment possible. Therefore, we do believe that it is necessary to define the concept of high quality security, which is translated in our current paper.

    2017-01-01

    Background and aim Therapeutic communication, the fundamental component of nursing, is a complex concept. Furthermore, the poor encounters between nursing student and patient demonstrate the necessity of instruction regarding therapeutic communication. The aim of this study was to define and clarify this important concept for including this subject in the nursing curriculum with more emphasis. Methods A literature search was conducted using keywords such as “nursing student”, “patient” and “therapeutic communication” and Persian-equivalent words in Persian databases (including Magiran and Medlib) and English databases (including PubMed, ScienceDirect, Scopus and ProQuest) without time limitation. After extracting concept definitions and determining characteristic features, therapeutic communication in nursing students was defined. Then, sample cases, antecedents, consequences and empirical referents of concept were determined. Results After assessing 30 articles, therapeutic communication defining attributes were as follows: “an important means in building interpersonal relationships”, “a process of information transmission”, “an important clinical competency”, “a structure with two different sections” and “a significant tool in patient centered care”. Furthermore, theoretical and clinical education and receiving educators’ feedback regarding therapeutic communication were considered as antecedents of the concept. Improving physical and psychological health status of patient as well as professional development of nursing students were identified as consequences of the concept. Conclusion Nursing instructors can use these results in order to teach and evaluate therapeutic communication in nursing students and train qualified nurses. Also, nursing students may apply the results to improve the quality of their interactions with patients, perform their various duties and meet patients’ diverse needs. PMID:28979730

  14. Long-term solar activity and terrestrial connections. Part II: at the beckon of the sun?

    Directory of Open Access Journals (Sweden)

    N. D. Diamantides

    Full Text Available The research task described herein aims at the structuring of an analytical tool that traces the time course of geophysical phenomena, regional or global, and compares it to the course of long-term solar conditions, long-term meaning decades or a few centuries. The model is based on the premise that since in a last analysis the preponderance of atmospheric, hydrospheric, and, possibly, some aspects of geospheric phenomena are, or have been, powered by energy issuing from the sun - either now or in the past - the long-term behavior of such phenomena is ultimately "connected" to long-term changes occurring in the sun itself. Accordingly, the proposed research firstly derives and models a stable surrogate pattern for the long-term solar activity, secondly introduces a transfer-function algorithm for modeling the connection between the surrogate and terrestrial phenomena viewed as partners in the connection, and thirdly probes the connection outcome for episodic or unanticipated effects that may arise due to the fact that in the present context, the connection, should it exist, is very likely nonlinear. Part I of the study presents the theory of the concept, while Part II demonstrates the concept's pertinence to a number of terrestrial phenomena.

  15. The diverse aims of science.

    Potochnik, Angela

    2015-10-01

    There is increasing attention to the centrality of idealization in science. One common view is that models and other idealized representations are important to science, but that they fall short in one or more ways. On this view, there must be an intermediary step between idealized representation and the traditional aims of science, including truth, explanation, and prediction. Here I develop an alternative interpretation of the relationship between idealized representation and the aims of science. I suggest that continuing, widespread idealization calls into question the idea that science aims for truth. If instead science aims to produce understanding, this would enable idealizations to directly contribute to science's epistemic success. I also use the fact of widespread idealization to motivate the idea that science's wide variety aims, epistemic and non-epistemic, are best served by different kinds of scientific products. Finally, I show how these diverse aims—most rather distant from truth—result in the expanded influence of social values on science. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Rykova, O.V.

    2017-09-01

    Full Text Available The topicality of the research in modern linguistics is defined by the importance of studying the problem of the dynamic nature of the concept content, the need to define the connection type between the concept and discourse as well as to reveal the dependence of the concept content and verbalization means from the type of discourse. The subject of the research is dynamic properties of the verbalization of a socially marked concept in American mass media discourse. The aim is to define the dynamics of structuring and explicating the knowledge about terrorism in mass media discourse. To reach the aim the following tasks are set: to determine the corpus of linguistic units which serve as verbalizers of the concept of terrorism in American mass media discourse; to define the dynamics of the verbal representation of the concept of terrorism in American mass media discourse as exemplified by metaphoric modelling. The practical applicability of the research consists in the possibility of using its main points and results in such academic courses as general linguistics, stylistics, cultural linguistics, special courses in cognitive linguistics, theory of conceptual metaphor, discourse study and in lexicographic practice.

    Full Text Available The aim of this article is to define the concepts of playing, working, gaming, and labouring, through a literature study, and to construct a typology. This typology will be used to create a field model that is structured by the horizontal parameters of qualitative-quantitative (characteristics and the vertical parameters of activity-result (in focus. It is shown how this model can be used to visualise different theoretical positions in empirical material, which connects to the concepts and their relations. Working and labouring are distinguished into a trans-historical and a historical, capitalist, category, and likewise playing and gaming, where the former is the trans-historical category and the latter the historical one. The main focus of the article, since working and labouring is well covered within the critical Marxist tradition, is on playing and its relation to working, with the aim of understanding and criticising the concept of playbour.

    2013-08-01

    Full Text Available Through this study we aim at performing an analysis of the concept of local interest, having as prerequisites the doctrinal debates regarding the general interest. The examination of this concept occurs in relation with the new trends, as concerns the exercise of competences at local level, respectively with the elements that define the interest of the community and its means of application within the life of the local community. Our research aims to establish theoretically the notion of local interest, an approach that we carry out within a difficult environment, whereas the notion of interest is fluctuating, being constantly modified under the pressure of the evolutions of social and economic needs. The results and the essential contribution of the material consist in the establishment of a framework that would offer to local authorities the practical possibilities for identifying the landmarks that surround this concept and that has to be harmonised with the values of modernity in order to respond better to the needs that are expressed.

    2017-02-01

    About 25 years ago, concept mapping was introduced in the Netherlands and applied in different fields. A collection of concept mapping projects conducted in the Netherlands was identified, in part in the archive of the Netherlands Institute of Mental Health and Addiction (Trimbos Institute). Some of the 90 identified projects are internationally published. The 90 concept mapping projects reflect the changes in mental health care and can be grouped into 5-year periods and into five typologies. The studies range from conceptualizing the problems of the homeless to the specification of quality indicators for treatment programs for patients with cystic fibrosis. The number of concept mapping projects has varied over time. Growth has been considerable in the last 5 years compared to the previous 5 years. Three case studies are described in detail with 12 characteristics and graphical representations. Concept mapping aligns well with the typical Dutch approach of the "Poldermodel." A broad introduction of concept mapping in European countries in cooperation with other countries, such as the United States and Canada, would strengthen the empirical basis for applying this approach in health care policy, quality, and clinical work.

  2. Midline body actions and leftward spatial Aiming in patients with spatial neglect

    Directory of Open Access Journals (Sweden)

    Amit eChaudhari

    2015-07-01

    Full Text Available Spatial motor-intentional Aiming bias is a dysfunction in initiation/execution of motor intentional behavior, resulting in hypokinetic and hypometric leftward movements. Aiming bias may contribute to posture, balance and movement problems and uniquely account for disability in post-stroke spatial neglect. Body movement may modify and even worsen Aiming errors, but therapy techniques such as visual scanning training do not take this into account. Here, we evaluated 1 whether instructing neglect patients to move midline body parts improves their ability to explore left space, and 2 whether this has a different impact on different patients. A 68-year-old woman with spatial neglect after a right basal ganglia infarct had difficulty orienting to and identifying left-sided objects. She was prompted with four instructions: look to the left, point with your nose to the left, point with your [right] hand to the left, and stick out your tongue and point it to the left. She oriented leftward dramatically better when pointing with the tongue/nose, than she did when pointing with the hand. We then tested 9 more consecutive patients with spatial neglect using the same instructions. Only four of them made any orienting errors. Only one patient made >50% errors when pointing with the hand, and she did not benefit from pointing with the tongue/nose. We observed that pointing with the tongue could facilitate left-sided orientation in a stroke survivor with spatial neglect. If midline structures are represented more bilaterally, they may be less affected by Aiming bias. Alternatively, moving the body midline may be more permissive for leftward orienting than moving right body parts. We were not able to replicate this effect in another patient; we suspect that the magnitude of this effect may depend upon the degree to which patients have directional akinesia, spatial Where deficits, or cerebellar/frontal cortical lesions. Future research could examine these

    Doré, Isabelle; Caron, Jean

    Objectives This article aims to situate the concept of mental health in a historical perspective. This article presents the most commonly used measurement tools in Canada and elsewhere in the world to assess specific and multiple dimensions of mental health; when available, psychometric properties are discussed. Finally, research findings on quality of life and mental health determinants are presented.Methods A literature review of concepts, measurement and determinants of mental health is presented in this paper. The selection of measurement scales presented is based on the findings of the research reports conducted by the second author, an expert on mental health measures, for Health Canada and Statistics Canada.Results Mental health is more than the absence of mental illness; rather it is a state of complete well-being, which refers to our ability to enjoy life and deal with the challenges we face. Accordingly, mental health and mental illness are not extremes of the same continuum, but distinct yet correlated concepts. The traditional conceptualization suggesting that mental health represents simply the absence of mental illness has been replaced, in the last few decades, by a more holistic characterization, which directly concerns public health. The components of mental health include emotional well-being/quality of life (QOL) and psychological and social well-being. Mental health influences the personal and social functioning of individuals, justifying the importance of intervening upstream to promote mental health. Specific scales are relevant for obtaining a detailed measure of one aspect of well-being in particular (emotional/quality of life, psychological or social well-being); however, to account for the global mental health status, measurement tools that integrate all three forms of well-being (emotional, psychological and social) should be privileged. A diversity of determinants at the individual, social and neighbourhood levels influence quality of

    Delays in construction sites occur due to systematic additions of time waste in various activities that are part of the construction process. Work-time waste is non-adding value activity which used to differentiate between physical construction waste found on site and other waste which occurs during the construction process. The aim of this study is identification using the concept of Value Stream Mapping (VSM) to reduce of work-time waste as applied the smart construction management.VSM analysis is a method of business process improvement. The application of VSM began in the manufacturing community. The research method base on theoretically informed case study and literature review. The data have collected using questionnaire through personal interviews from 383 respondents on construction project in Indonesia. The results show that concept of VSM can identify causes of work-time waste. Base on result of questioners and quantitative approach analysis was obtained 29 variables that influence of work-time waste or non-value-adding activities. Base on three cases of construction project founded that average 14.88% of working time was classified as waste. Finally, the concept of VSM can recommend to identification of systematic for reveal current practices and opportunities for improvement towards global challenges. The concept of value stream mapping can help optimize to reduce work-time waste and improve quality standard of construction management. The concept is also can help manager to make a decision to reduce work-time waste so as to obtain of result in more efficient for performance and sustainable construction project.

    The Environmentally Responsible Aviation Project aimed to develop aircraft technologies enabling significant fuel burn and community noise reductions. Small incremental changes to the conventional metallic alloy-based 'tube and wing' configuration were not sufficient to achieve the desired metrics. One airframe concept identified by the project as having the potential to dramatically improve aircraft performance was a composite-based hybrid wing body configuration. Such a concept, however, presented inherent challenges stemming from, among other factors, the necessity to transfer wing loads through the entire center fuselage section which accommodates a pressurized cabin confined by flat or nearly flat panels. This paper discusses a finite element analysis and the testing of a large-scale hybrid wing body center section structure developed and constructed to demonstrate that the Pultruded Rod Stitched Efficient Unitized Structure concept can meet these challenging demands of the next generation airframes. Part II of the paper considers the final test to failure of the test article in the presence of an intentionally inflicted severe discrete source damage under the wing up-bending loading condition. Finite element analysis results are compared with measurements acquired during the test and demonstrate that the hybrid wing body test article was able to redistribute and support the required design loads in a severely damaged condition.

    This paper explores notions of fatherhood and their linkages to fertility desires and intentions among a treatment-naïve cohort of Xhosa-speaking male key informants living with HIV aged 20-53 in Cape Town, South Africa. Analysis is based on an initial 27 and 20 follow up interviews with men who were part of a study that assessed the acceptability of safer conception and alternative parenting strategies among men and women newly diagnosed with HIV to inform an intervention. Grounded theory analysis revealed themes related to the cultural imperative of biologically-connected fatherhood. Certain safer conception strategies aimed at minimising the risk of HIV transmission were perceived as threats to paternity. These findings suggest that understanding of social and cultural beliefs related to notions of paternity and fatherhood may inform the implementation of acceptable safer conception options for HIV-positive men and their infected and uninfected female partners in a high HIV prevalence, low-resource setting.

    Over the years, the concept technology has modified, especially from the viewpoint of the development of scientific knowledge as well as the philosophical and artistic aspects. However, the concept of technology in nursing are still poorly understood. Only small qualitative studies, especially in Iran, have investigated this phenomenon and they just are about information technology. The aim of this study is to gain a better understanding of the concept of technology in the view of Iranian nurses. This study was qualitative explorative study which was done with a purposeful sampling of 23 nurses (staffs, supervisors and chief nurse managers) working in Isfahan hospitals. Unstructured interviews were including 13 individual interviews and 2 focused-group interviews. In addition to this, filed notes and memos were used in data collection. After this data transcribing was done and then conventional content analysis was used for data coding and classification. The results showed that there are various definitions for technology among nurses. In the view of nurses, technology means using new equipment, computers, information technology, etc). Data analysis revealed that nurses understand technology up to three main concepts: Change, Equipment and Knowledge. In deep overview on categories, we found that the most important concept about technology in nursing perspective is equipment. Therefore, it is necessary to develop deep understanding about the possible concepts technology among nurses. We suppose that technology concepts must be defined separately in all disciplines.

    Quantum Theory is one of the pillars of modern science developed over the last hundred years. In this review we introduce, step by step, the quantum theory understood as a mathematical model describing quantum experiments. We start with splitting the experiment into two parts: a preparation process and a measurement process leading to a registration of a particular outcome. These two ingredients of the experiment are represented by states and effects, respectively. Further, the whole picture of quantum measurement will be developed and concepts of observables, instruments and measurement models representing the three different descriptions on experiments will be introduced. In the second stage, we enrich the model of the experiment by introducing the concept of quantum channel describing the system changes between preparations and measurements. At the very end we review the elementary properties of quantum entanglement. The text contains many examples and exercise covering also many topics from quantum information theory and quantum measurement theory. The goal is to give a mathematically clear and self-containing explanation of the main concepts of the modern language of quantum theory (Authors)

    The paper will present the progress in developing the Integral Inherently Safe Light Water Reactor (12S-LWR) concept. This new concept aims to combine the competitive economics of a large nuclear power plant, with enhanced safety achieved by the integral primary circuit configuration (previously considered only for PWRs with power levels not exceeding several hundred MWc), and with enhanced accident tolerance (to address concerns after the Fukushima Dai-lchi accidents). Several new technologies are being developed to enable this concept, including novel silicide fuel and micro-channel primary heat exchangers. This project is performed by a multi-disciplinary multi-organization team led by Georgia Tech, including academia, a national laboratory, nuclear industry, and a power utility, wit expected participation of the University of Zagreb.

    Full Text Available Long-term studies of shear zones have included collection of data on fractures showing no indication of displacement which are termed as 'blank' fractures. A method aimed at mapping fault structures and stress fields has been developed on the basis of results of paragenetic analysis of measurements of abundant fractures. The method is termed as 'specialized mapping', firstly, due to its specific structural goal so that to distinguish it from the conventional geological mapping of regions in nature, and, secondly, because of the specific procedure applied to refer to fractures as references to decipher fault-block patterns of natural regions. In Part 1, basic theoretical concepts and principles of specialized mapping are described. Part 2 is being prepared for publication in one of the next issues of the journal; it will cover stages of the proposed method and describe some of the cases of its application.In terms of general organizational principles, specialized mapping is similar to other methods based on structural paragenetic analysis and differs from such methods in types of paragenesises viewed as references to reveal crustal fault zones. Such paragenesises result from stage-by-stage faulting (Fig 2 and Fig. 7 during which stress fields of the 2nd order are regularly changeable within the shear zone. According to combined experimental and natural data, a complete paragenesis of fractures in the shear zone includes a major (1st order fault plane and fractures of other seven types, R, R’, n, n’, t, t’ and T (2nd order (Fig. 4 and Fig 8. At the fracture level, each of them corresponds to a paragenesis including three nearly perpendicular systems of early ruptures (Fig. 1, which are based on two classical patterns of conjugated fractures, one of which is consistent with the position of the fault plane (Fig. 3. Taking into account that strike-slip, reverse and normal faults are similar in terms of mechanics (i.e. they are formed due to

    [EN] The concept of “ineffable space” unquestionably occupies a central place in Le Corbusier's architectural theory after 1945. Far from being a portmanteau or a signifier devoid of meaning, the concept of ineffable space is aimed at conceiving the height of aesthetic and spiritual experience rendered possible by architecture. This is as much to realise plastic emotion felt in front of masterpiece from the past as to describe the experiential quality that the architect seeks to p...
