    2007-01-01

    Using self-determination theory, two studies found that holding an extrinsic, relative to an intrinsic, work value orientation was associated with less positive outcomes (i.e. less satisfaction with, dedication to and vitality while on the job) and more negative outcomes (i.e. higher emotional exhaustion, short-lived satisfaction after successful goal-attainment, and turn-over intention). These relations were not limited to job outcomes, but also emerged using indicators of employees' general...

    Compared to other intervention modalities, there are relatively few outcome studies of gestalt therapy. This study aimed to address this gap by evaluating the therapeutic effects of four gestalt-oriented group workshops designed to enhance well-being in professionals trained as social workers, counselors, and psychologists. The results of this preliminary, uncontrolled study indicated that the 55 participants had better emotional well-being and experienced a heightened sense of hope following the workshops. The factors leading to these positive outcomes are discussed. PMID:23252818

  7. SOFTWARE REUSE AND OBJECT ORIENTED APPROACH

    Directory of Open Access Journals (Sweden)

    1995-02-01

    Full Text Available Software reuse is defined as the reuse of information and products of a previously developed software system in the development process of a new software system. The purpose of software reuse is to reduce the development cost and the time, while increasing the software quality. Constructing a library of software components and using them in developing complex software systems was first proposed by Dough McIlroy in 1968. Since then programming languages, tools and techniques have changed a lot, but component oriented software reuse is still accepted as an important solution to solve the software crisis. Object oriented approach encourages component reuse, by inheritance and encapsulation. But in order to accomplish a succesful reuse program in an organization, a well-planned and coordinated managenment is essential. In this paper, an object oriented software development process is introduced and in order to instituionalize software reuse a strategy is proposed.

    Our understanding of short-term recognition memory can be enhanced by careful choice and control of test materials. Theory-driven manipulation of memory test stimuli, including visual textures, human faces, and complex sounds, minimize individual differences and make it possible to predict recognition performance for specific combinations of stimulus items. This stimulus-oriented approach to memory reveals that stimulus similarity plays two different important roles in recognition memory. By ...

  9. Market oriented approach by public utilities

    Energy Technology Data Exchange (ETDEWEB)

    Mantel, J.J.; Verkuil, J.M.

    1989-08-01

    Public utilities, especially the larger ones, have an image of being inefficient, technocratic and bureaucratic institutions, unresponsive to modern lifestyles, growing consumerism, differentiated customer needs and changing social values. Improving this image and increasing customer satisfaction requires the adoption of a systematic market oriented approach, based on an appropriate segmentation of the client and general public. This article gives the broad outline of such an approach followed by some generally applicable practical recommendations. Finally it stresses the importance of human aspects of organizational behaviour and, consequently, the crucial part of corporate culture. 2 figs., 1 tab.

  10. Agent oriented approach to handling medical data.

    Science.gov (United States)

    Druzovec, Marjan; Welzer, Tatjana; Brumen, Bostjan

    2005-02-01

    Medical treatment of a patient could be represented as a circle of the following actions: examination, diagnostics, and therapy. The aims of the actions are to find out the patient's state of health and consequently to conclude about possible diseases and finally to choose a suitable therapy. In long term, the circle of actions repeat as long as the patient is not healthy. Efficiency of this treatment depends on the knowledge and the experiences of the physicians involved. Information technology offers many possibilities to help the physicians increase the efficiency and the quality of this work. In the article, we present an agent-oriented computer-based health care service, which uses information from different data sources that are physically distributed across several sites. Such a decentralized approach mirrors the organizational structure of a health service and it is very similar to an agent-oriented view of the world. PMID:15839331

    Full Text Available This paper describes techniques for designing both front & back end of a data warehouse in such a way that companies can continue to progress their warehouse and query tools as their business changes,customer demands changes, instead of continuously having to estructure and rewrite their existing tools. Object –Oriented approach are driving the current development of ODBMS that will handle complex objects, inheritance and other features that enable direct implementation technology that is being extended to combine data management capabilities with application of logical rules to provide more refined information to management. Object-oriented approach is used in different areas i.e Software Engg, Database Management System and Latest Approach is used in Data warehouse. Object-Oriented envelopment involves more than learning a program, it includes capability for development. A purely Object –Oriented tool like Java, Smalltalk , or the object –oriented use of C++ requires that problem domains be conceptualized in terms of the paradigm inherent in object technology. Most research in Object-oriented programming (OOP including object –oriented database Management systems (OODBMS, is concerned with supporting users which are not served well by more conventional technology. Our research has been from a different point of view – our primary motivating factor is toshow how existing applications can be enhanced using object –oriented Technology.

  15. Risk evaluation: A cost-oriented approach

    Rogers, B.H.

    1998-02-03

    This method provides a structured and cost-oriented way to determine risks associated with loss and destruction of industrial security interests consisting of material assets and human resources. Loss and destruction are assumed to be adversary perpetrated, high-impact events in which the health and safety of people or high-value property is at risk. This concept provides a process for: (1) assessing effectiveness of all integrated protection system, which includes facility operations, safety, emergency and security systems, and (2) a qualitative prioritization scheme to determine the level of consequence relative to cost and subsequent risk. The method allows managers the flexibility to establish asset protection appropriate to programmatic requirements and priorities and to decide if funding is appropriate. The evaluation objectives are to: (1) provide for a systematic, qualitative tabletop process to estimate the potential for an undesirable event and its impact; and (2) identify ineffective protection and cost-effective solutions.

  17. The bright side of brooding: State orientation increases positive emotions about positive outcomes.

    Science.gov (United States)

    van Putten, Marijke

    2015-12-01

    Research has by and large shown the negative effects of state orientation, that brooding over past events (i.e., state orientation) leads to more negative emotions and less well-being than quickly getting over past events (i.e., action orientation). However, this past research has primarily focused on how people cope with negative events and bad outcomes. The present research focuses on how people cope with positive events with good outcomes. Study 1 found that state-oriented people felt better after a windfall than action-oriented people. Study 2 found that state-oriented people felt not only worse when things turned out bad but also better when things turned out well than action-oriented people. Study 3 replicated the positive effect of state orientation on positive emotions with an experimental induction of action vs. state orientation. These results show that in positive situations state orientation can have emotional benefits - in other words, they show the bright side of brooding. PMID:25434289

    General causality orientations are motivational styles that are indicative of a person's belief about personal change and their motivation to change. The purpose of the current study was to investigate whether causality orientations were associated with marijuana treatment outcomes in a sample of marijuana-dependent individuals. A total of 74 participants (66% male) were recruited from the Seattle, Washington area and randomly assigned to receive a combination of motivational enhancement and cognitive behavioral therapy or the combination treatment plus additional "check-up" sessions. Follow-up assessments evaluated frequency of use, use-related problems, and marijuana use disorder symptoms through 9months. Causality orientations were relatively stable over time. Posttreatment Autonomy orientations were associated with lower frequency of use and Controlled orientations were associated with a reduction in use, problems, and marijuana use disorder symptoms. Autonomy and Controlled orientations were associated with readiness to change. Results suggest that both autonomous and controlled orientations have implications for response to treatment; perhaps for different reasons. Causality orientations may be a promising avenue of research to predict treatment response and outcome. PMID:26562679

  7. Nuclear quality assurance operating philosophy: A quality-oriented approach

    International Nuclear Information System (INIS)

    Quality assurance programs have been part of the nuclear utility management process since the publication of the draft of 10CFR50 Appendix B in the late 1960s. The unwritten operational philosophy of nuclear quality assurance organizations focused on compliance with federal regulations. Adverse experiences, including operational events and extended shutdowns, prompted the gradual adoption of isolated practices extending beyond compliance orientation. These practices have an orientation that accommodates a definition of quality, a perspective of the role of nuclear quality assurance organizations in the overall concept of defense-in-depth, a definition of the segments of the nuclear quality assurance mission, and recent advances in the understanding of self-assessment. Observation of these practices at various nuclear utilities resulted in a syntheses of practices and approaches into a coherent quality-oriented nuclear quality assurance operating philosophy that is not totally adopted at any one utility

    Full Text Available This paper concerns sustainable approaches to design for learning, emphasising the need for designs to be able to thrive outside of the protective niches of project-based innovation. It builds on the “in medias res” framework and more specifically on a forward-oriented approach to design for learning: one that takes a pro-active design stance with respect to each of the phases of an extended lifecycle. We draw on fieldwork notes and interview data to describe two cases that illustrate some of the key features of the approach. Recommendations for further R&D in the area of design for learning are provided, derived from the theoretical framework, and illustrated in this paper.

  15. A Service Oriented Approach to Modeling Interdisciplinary Environmental Systems

    Science.gov (United States)

    Castronova, A. M.; Goodall, J. L.

    2011-12-01

    Interdisciplinary research often requires the use of multiple data sources, models, and analysis routines coupled together in a workflow to answer a single research question. Coupling these computational resources into a workflow can be accomplished using various tools, but each of these tools requires the developer to follow a specific interface protocol to ensure that all components within the system remain compliant. Unfortunately, not all of the resources required for an analysis can be easily "wrapped" into a compliant form due to platform dependencies, computer architecture requirements, or programming language incompatibilities. Therefore, a more generic, service-oriented approach is needed that enables individual models to operate as intended and interact with other models through web service calls. This work presents a method for coupling independent models using web services to meditate communication. It consists of both client and server-side software. The client-side software extends a loosely integrated modeling environment for coupling data and models into configurations. The server-side software consists of software required for exposing datasets and models as web services. We build from the Open Modeling Interface (OpenMI) version 2.0 standard and demonstrate how it can be used to perform service-oriented simulations. We describe the design and implementation of both server and client-side software, the application of the software as part of an urban flood warning system, and offer suggestions for future work needed to advance service-oriented modeling of interdisciplinary environmental systems.

    Full Text Available Problem statement: Object and component technologies, rapidly maturing branches of information technology, have been becoming pervasive elements of systems development, especially the recently popular Internet applications and thus leading to increased complexity and at the same time broader range of applications. Approach: This needs to be understood in order to maximize its benefits and applications with consistent results. However, mainstream Object Oriented Systems Development (OOSD, consisting of Object Oriented Analysis and Design (OOAD and Object- Oriented Programming (OOP, has a history of difficulties and is still struggling to gain prevalent acceptance. Results: There have been number of studies and experiments conducted by experts and researchers in the past which provides a solid base to take up this study and look into various intricacies present. There have been several studies and focused efforts in this direction which laid down the basis for a segment of people to form the opinion as ?technology adoption is mostly the result of marketing forces, not scientific evidence? whereas there have been another segment that believes that object technology is ?still long on hype and short on results ...?. The gurus of OOSD continue to tout its vast superiority over conventional systems development, even to the extent of developing a unified software development process. Conclusion: The advocates of OOSD claim many advantages including easier modeling, increased code reuse, higher system quality and easier maintenance. It is well understood that analysis and design are extremely critical aspects of successful systems development especially in the case of OOSD. As the development of any successful information system must begin with a well-conceived and implemented analysis and design, this study will focus on the most recent empirical evidence on the pros and cons of OOAD.

  18. Outcome orientation - a misconception of probability that harms medical research and practice

    CERN Document Server

    Humphrey, Parris Taylor

    2014-01-01

    Uncertainty is an everyday experience in medical research and practice, but theory and methods for reasoning clearly about uncertainty were developed only recently. Confirmation bias, selective memory, and many misleading heuristics are known enemies of the insightful clinician, researcher, or citizen; but other snares worth exposing lurk in how we reason about uncertainty in our everyday lives. Here we draw attention to a cognitive bias described by Konold as the "outcome orientation" - little known or possibly unknown to those outside the field of probability pedagogy - and point out how this form of reasoning creates hazards for medical research and practice.

    2008-04-01

    Full Text Available Game assets are portable between games. The games themselves are, however, dependent on the game engine they were developed on. Middleware has attempted to address this by, for instance, separating out the AI from the core game engine. Our work takes this further by separating the game from the game engine, and making it portable between game engines. The game elements that we make portable are the game logic, the object model, and the game state, which represent the game's brain, and which we collectively refer to as the game factor, or G-factor. We achieve this using an architecture based around a service-oriented approach. We present an overview of this architecture and its use in developing games. The evaluation demonstrates that the architecture does not affect performance unduly, adds little development overhead, is scaleable, and supports modifiability.

  2. A Task-oriented Approach to Search Engine Usability Studies

    Full Text Available Usability is a multi-dimensional characteristic of a computer system. This paper focuses on usability as a measurement of interaction between the user and the system. The research employs a task-oriented approach to evaluate the usability of a meta search engine. This engine encourages and accepts queries of unlimited size expressed in natural language. A variety of conventional metrics developed by academic and industrial research, including ISO standards, are applied to the information retrieval process consisting of sequential tasks. Tasks range from formulating (long queries to interpreting and retaining search results. Results of the evaluation and analysis of the operation log indicate that obtaining advanced search engine results can be accomplished simultaneously with enhancing the usability of the interactive process. In conclusion, we discuss implications for interactive information retrieval system design and directions for future usability research.

  3. New approach to thermally orient nuclei in antiferromagnetic insulators

    International Nuclear Information System (INIS)

    Full text: We present a new method for obtaining substantial zero field thermal equilibrium nuclear orientation of the magnetically dominant species in antiferromagnetic insulators, through manipulation of the dominant nuclear spin lattice relaxation (NSLR) processes in these recalcitrant hosts. Antiferromagnets(AF) provide comparable internal hyperfine fields to ferromagnets(F), are more prevalent, and provide much narrower NMR line widths due to the absence of distributions of demagnetising fields compared with the ubiquitous metallic F hosts (e.g. Fe, Co and Ni) which have dominated NMRON studies. The failure, in general, to obtain substantial nuclear orientation in the 3D AF's has hitherto severely limited the application of NMRON, including pulsed NMRON nuclear spin relaxation and multi-quantum studies. The best studied being MnCl2.4H2O, through its singular 'magnon cooling' attribute at the spin flop field. (For a recent review of nuclear orientation and NMRON in the study of magnetic insulators see). ur approach is to recognise that multi-magnon (electron) NSLR processes in AF's may be re-invoked to a considerable extent by broad-banding a major contributor to the magnon scattering process through heterogeneous mixing of the halide ligands. In AF MnCl2.4HO conventional zero field CWNMR demonstrates that the static internal fields generated at the low symmetry halide sites are comparable with those generated at the proton sites from the single magnetic Mn ion residing in the centre of any one of the four distorted octahedra of the four sublattice magnetic unit cell. By reciprocity it follows that there are substantial static fields, through transferred hyperfine interaction, acting on the Mn from the halide sites. Fluctuations of these fields with the appropriate spectral distribution in the transverse plane at the Mn site is a potential NSLR mechanism. By replacing ?40% of the chlorine atoms with bromide atoms, we have been able to obtain up to 40% zero field gamma anisotropy in (54Mn)Mn(Cl0.6Br0.4)2.4H2O on initial cool down, which may be compared with 5% and 14% in the terminal compounds, (54Mn)MnCl2.4H2O and (54Mn)MnBr2.4H2O, respectively. Moreover, we have been able to discern with NMRON precision that the mixed halide AF compound provides a unique spin down site

    Purpose This present study tests the proposition that an economic strengthening intervention for families caring for AIDS-orphaned adolescents would positively affect adolescent future orientation and psychosocial outcomes through increased asset-accumulation (in this case, by increasing family savings). Methods Using longitudinal data from the cluster-randomized experiment we ran generalized estimating equation (GEE) models with robust standard errors clustering on individual observations. To examine whether family savings mediate the effect of the intervention on adolescents’ future orientation and psychosocial outcomes, analyses were conducted in three steps: (1) testing the effect of intervention on mediator; (2) testing the effect of mediator on outcomes, controlling for the intervention; and (3) testing the significance of mediating effect using Sobel-Goodman method. Asymmetric confidence intervals for mediated effect were obtained through bootstrapping—to address the assumption of normal distribution. Results Results indicate that participation in a matched Child Savings Account program improved adolescents’ future orientation and psychosocial outcomes by reducing hopelessness, enhancing self-concept, and improving adolescents’ confidence about their educational plans. However, the positive intervention effect on adolescent future orientation and psychosocial outcomes was not transmitted through saving. In other words, participation in the matched Child Savings Account program improved adolescent future orientation and psychosocial outcomes regardless of its impact on reported savings. Conclusions Further research is necessary to understand exactly how participation in economic strengthening interventions, for example, those that employ matched Child Savings Accounts, shape adolescent future orientation and psychosocial outcomes: what, if not savings, transmits the treatment effect and how?

    2014-01-01

    Evidence-based medical practice requires that clinical guidelines need to be documented in such a way that they represent a clinical workflow in its most accessible form. In order to optimize clinical processes to improve clinical outcomes, we propose a Service Oriented Architecture (SOA) based approach for implementing clinical guidelines that can be accessed from an Electronic Health Record (EHR) application with a Web Services enabled communication mechanism with the Enterprise Service Bus. We have used Business Process Modelling Notation (BPMN) for modelling and presenting the clinical pathway in the form of a workflow. The aim of this study is to produce spontaneous alerts in the healthcare workflow in the diagnosis of Chronic Obstructive Pulmonary Disease (COPD). The use of BPMN as a tool to automate clinical guidelines has not been previously employed for providing Clinical Decision Support (CDS). PMID:25160142

    Full Text Available Abstract Background Patient-centered medicine is developing alongside the concepts of personalized medicine and tailored therapeutics. The main objective of patient-centered medicine is to improve health outcomes of individual patients in everyday clinical practice, taking into account the patient’s objectives, preferences, values as well as the available economic resources. Discussion Patient-centered medicine implies a paradigm shift in the relationship between doctors and patients, but also requires the development of patient-oriented research. Patient-oriented research should not be based on the evaluation of medical interventions in the average patient, but on the identification of the best intervention for every individual patient, the study of heterogeneity and the assignment of greater value to observations and exceptions. The development of information-based technologies can help to close the gap between clinical research and clinical practice, a fundamental step for any advance in this field. Summary Evidence-based medicine and patient centered medicine are not contradictory but complementary movements. It is not possible to practice patient-centered medicine that is not based on evidence, nor is it possible to practice evidence-based medicine at a distance from the individual patient.

  10. Behavior-oriented approaches to reducing youth gun violence.

    Science.gov (United States)

    Hardy, Marjorie S

    2002-01-01

    Advocacy groups on both sides of the guns issue frequently point to changing personal behavior--of both parents and children--as a key element in reducing gun violence among youth. Efforts to bring about these changes range from community-based campaigns, to laws and programs that encourage parents to store their guns safely, to educational initiatives that focus on keeping young children away from guns and encouraging youth to resolve disputes without violence. Unfortunately, these behavior-oriented programs have not shown great success in reducing youth gun violence. This article reviews the research surrounding behavioral approaches to gun violence prevention and highlights obstacles that hamper the effectiveness of these programs. Supportive communities can play a key role in protecting youth from violence in general, but the few community-based violence prevention programs that focus on youth have not been shown to decrease youth access to or use of guns. By and large, behavioral programs and legal interventions aimed at parents have not been proven to reduce youth gun violence. This may be due in part to parental misperceptions about children's risk of injury and ability to protect themselves. Children and youth are particularly difficult targets for behavioral change programs. Cognitive immaturity among younger children and perceptions of invulnerability among adolescents may be part of the reason. Most programs that seek to persuade youth to stay away from guns have not been proven effective. The author concludes that, although behavioral programs could be improved, overall they hold only limited promise for reducing youth gun violence. PMID:12194605

    Full Text Available Abstract Background The objective of this study was to examine the extent of surgical procedures, pathological findings, complications and outcome of patients treated in the last 12 years for gallbladder cancer. Methods The impact of a standardized more aggressive approach compared with historical controls of our center with an individual approach was examined. Of 53 patients, 21 underwent resection for cure and 32 for palliation. Results Overall hospital mortality was 9% and procedure related mortality was 4%. The standardized approach in UICC stage IIa, IIb and III led to a significantly improved outcome compared to patients with an individual approach (Median survival: 14 vs. 7 months, mean+/-SEM: 26+/-7 vs. 17+/-5 months, p = 0.014. The main differences between the standardized and the individual approach were anatomical vs. atypical liver resection, performance of systematic lymph dissection of the hepaticoduodenal ligament and the resection of the common bile duct. Conclusion Anatomical liver resection, proof for bile duct infiltration and, in case of tumor invasion, radical resection and lymph dissection of the hepaticoduodenal ligament are essential to improve outcome of locally advanced gallbladder cancer.

  14. On the relationship between justice judgments, outcomes and identity orientations among Iranian EFL learners: A structural equation model

    Directory of Open Access Journals (Sweden)

    Seyyed Ayatollah Razmjoo

    2015-06-01

    Full Text Available One problem which can be observed in the field of EFL/ESL learning is that a number of English major BA and MA students are not highly committed to their major and decide not to continue their graduate studies. Sometimes even graduate students from English majors prefer to extend their education or work in an unrelated field. This might be attributed to the extent to which they perceive evaluation procedures and outcomes as fair. Considering this, the present study investigates first the relationships between justice judgments, outcomes and identity orientations. The study, then, uses structural equation modeling in order to examine whether identity orientation has any mediating effect on the relationship between justice judgment and outcomes. Participants were74 students in Department of Foreign Languages and Linguistics, Shiraz University selected based on convenience sampling. They filled out three questionnaires on distributive and procedural justice judgments, rule compliance and outcome satisfaction, and personal and social identity orientations. The collected data was then analyzed using descriptive statistics, correlation, and structural equation modeling. Based on the obtained findings, procedural justice had significant positive correlation with rule compliance and distributive justice was significantly correlated with outcome satisfaction. The generated structural equation model also indicated that justice judgments only directly affected outcomes and identity had no mediating effect on the causal relationship between the two.

    This empirical study evaluated the moderating effects of unit customer orientation (CO) climate and climate strength on the relationship between service workers' level of CO and their performance of customer-oriented behaviors (COBs). In addition, the study examined whether aggregate COB performance influences unit profitability. Building on multisource, multilevel data, the study's results suggest that the influence of employee CO on employee COB performance is positive when the unit's CO climate is relatively high and that the constructs are unrelated when unit CO climate is relatively low. In addition, the data reveal that unit COB performance influences unit profitability by enhancing revenues without a concomitant increase in costs. The study's results underscore the theoretical importance of considering cross-level influencers of employee-level relationships and suggest that managers should focus on creating a climate that is supportive of COBs if their units are to profit from the recruitment, hiring, and retention of customer-oriented employees.

    2015-12-01

    In meta-analysis, dependent effect sizes are very common. An example is where in one or more studies the effect of an intervention is evaluated on multiple outcome variables for the same sample of participants. In this paper, we evaluate a three-level meta-analytic model to account for this kind of dependence, extending the simulation results of Van den Noortgate, López-López, Marín-Martínez, and Sánchez-Meca Behavior Research Methods, 45, 576-594 (2013) by allowing for a variation in the number of effect sizes per study, in the between-study variance, in the correlations between pairs of outcomes, and in the sample size of the studies. At the same time, we explore the performance of the approach if the outcomes used in a study can be regarded as a random sample from a population of outcomes. We conclude that although this approach is relatively simple and does not require prior estimates of the sampling covariances between effect sizes, it gives appropriate mean effect size estimates, standard error estimates, and confidence interval coverage proportions in a variety of realistic situations.

  19. An intelligent dynamic simulation environment: An object-oriented approach

    International Nuclear Information System (INIS)

    This paper presents a prototype simulation environment for nuclear power plants which illustrates the application of object-oriented programming to process simulation. Systems are modeled using this technique as a collection of objects which communicate via message passing. The environment allows users to build simulation models by selecting iconic representations of plant components from a menu and connecting them with the aid of a mouse. Models can be modified graphically at any time, even as the simulation is running, and the results observed immediately via real-time graphics. This prototype illustrates the use of object-oriented programming to create a highly interactive and automated simulation environment. 9 refs., 4 figs

    2008-08-01

    Full Text Available Abstract The current approaches to the quality control of herbal medicines are either compound-oriented or pattern-oriented, the former targeting specific components with some known chemical properties and the latter targeting all detectable components. The marker approach uses specific chemical compounds with known molecular structures, while the multi-compound approach uses both chemical compounds with known structures and those with partial chemical information e.g. retention times, mass spectra and ultraviolet spectra. Apart from chromatographic techniques, new techniques such as oscillating and electrochemistry fingerprints have been developed for quality control. Chemometric resolution methods are widely used for component deconvolution and data comparison. Pattern recognition techniques are used for authentication of herbal medicines.

  4. Emotional Value of Applied Textiles : Dialogue-oriented and participatory approaches to textile design

    DEFF Research Database (Denmark)

    Bang, Anne Louise

    2011-01-01

    The present PhD thesis is conducted as an Industrial PhD project in collaboration with the Danish company Gabriel A/S (Gabriel), which designs and produces furniture textiles and ‘related products’ for manufacturers of furniture. A ‘related textile product’ is e.g. processing of piece goods, upholstery, mounting etc. This PhD project addresses the challenges of the textile industry, where the global knowledge economy increasingly forces companies to include user-participation and value innovation in their product development. My project revolves around the challenges which the textile designers at Gabriel face while trying to implement an innovative and process-oriented business strategy. The focal point has been the section of the strategy which aims at developing Blue Ocean products, which have a functional and an emotional value for the user. The thesis examines and explores emotional value of applied textiles. The objective is to operationalise the strategic term ‘emotional value’ as it relates to applied textiles. The procedure includes the development of user- and stakeholder-centred approaches, which are valuable for the textile designer in the design process. The research approach is application-oriented and practical. In chapter two, I explain the ‘programmatic approach’ to design research, in which design experiments are the core of the project. The research programme is dynamic; it is developing in the course of the project and in tandem with the knowledge generated. The outcome of the research is ‘exemplary’ and the research contributions are presented as ‘exemplars’, ‘frameworks’, ‘tools’ and ‘structures’, which are relevant for the design process or can be the subject of critique and further investigation by other researchers. The project is a contribution to the broad and multifaceted field of design research with a particular focus on textile design including the discourse and methodology used in the field of design. In addition the project relates to the Participatory Design approach and to the design research fields which focus on emotional aspects of design. Based on my experiences with the programmatic approach I propose a distinction between ’overall challenges’ and ’research questions’. I view this thesis as a research contribution which facilitates a programmatic approach to a project such as this one. The ‘overall challenges’ (challenges within the field of textile design) is a constant variable against which the programme (challenges which Gabriel’s textile designers face) can be benchmarked. Thus the ‘research questions’ (emotional value and user and stakeholder involvement) are ‘shapable’ and situation-specific, and they constantly interact with the experiments (procedures of user and stakeholder involvement). In the course of the thesis I explain and elaborate on four themes each of which contributes to the outcome of the project. 1) Creating a frame of reference for the textile design process and a systematic approach to applied textiles. In chapter three I compare a textile design process with Donald Schön’s definition of design as ‘a conversation with the materials of a situation’. Subsequently, through design experiments involving several participants, I develop the ‘Tripod Approach’– a structured and systematic approach to design and research of applied textiles. 2) Understanding and exploring emotional value related to design of applied textiles. In chapter four I argue – based on Jesse Prinz’s and Antonio Damasio’s emotion research – for a perception of emotional value of applied textiles which acknowledges bodily feedback as a core concept in the process which leads to ‘emotion’. This approach is used when exploring and adjusting Patrick Jordan’s framework of ‘the four pleasures’ to the study of emotional value of applied textiles as presented in this thesis. My experiments lead to the creation of a framework of four adjusted categories of ‘pleasure’ based on which a group of stakeholders can e

    Science.gov (United States)

    Wenzel, Michael

    2002-08-01

    Previous research has yielded inconsistent evidence for the impact of justice perceptions on tax compliance. This article suggests a more differentiated view on the basis of 2 congenial theories of procedural and distributive justice. The group-value model and a categorization approach argue that taxpayers are more concerned about justice and less about personal outcomes when they identify strongly with the inclusive category within which procedures and distributions apply. Regression analyses of survey data from 2,040 Australian citizens showed that 2 forms of tax compliance (pay-income reporting and tax minimization) were determined by self-interest variables. For 2 other forms (nonpay income and deductions), inclusive identification had an additional effect and moderated the effects of self-interest and justice variables as predicted. PMID:12184568

    Web services should be dependable, because businesses rely on them. For that purpose the Service Oriented Architecture has standardized specifications at a syntactical level. In this paper, we demonstrate how such specifications are used to derive semantic models in the form of (timed) automata. These can be used to model check functional and behavioural properties of a given service. Since there might be several specifications dealing with different aspects, one must also check that these automata are consistent, where we propose to set up a suitable simulation relation. The proposed techniques are illustrated with a small case study

    There appears to be a lack of evidence concerning the effect of rehabilitation programmes for the long-term sick. More focus in this area would supplement an approach that has been directed toward process evaluation of rehabilitation programmes. It was the purpose of this study to shed light on individual factors and health care and social welfare-related factors, which play a role for the outcome of rehabilitation programmes.

    Janoff-Bulman, Ronnie; Sheikh, Sana; Baldacci, Kate

    2008-01-01

    Recent critiques of moral psychology and the contemporary culture wars highlight the need for a better understanding of diverse moral perspectives. A model of moral motives is proposed. The fundamental approach-avoidance distinction in motivation is crossed with self-other focus to create four moral motives: Self-Restraint (avoidance-self), Social Order (avoidance-other), Self-Reliance (approach-self), and Social Justice (approach-other). Three studies explored these motives in the context of...

    2010-01-01

    This study tested crucial components of Gray's reinforcement sensitivity theory that have generally been overlooked in the literature. We tested whether the perceived amount of reward moderates the behavioral approach system (BAS) and the importance of reward mediates BAS in the prediction of job satisfaction and organizational commitment. Results from 514 participants employed in part-time and full-time jobs provided support for our model, such that the indirect effect of BAS through the importance of reward was strongest when reward was provided. This model advances our understanding of reinforcement sensitivity theory and offers a solid foundation for predicting outcomes in everyday life. PMID:20923087

    This article presents the progressive implementation of the state-oriented approach (APE) for centralized control procedures in French nuclear power plants. The implementation began in the years 1982-83 and it concerned only the circuits involved in engineered safeguard systems such IS (safety injection), EAS (containment spray system) and GMPP (reactor coolant pump set). In 2003 the last PWR unit switched from the event oriented approach to APE for post-accidental situations.

  2. Small Firm Internet Adoption: a market oriented approach

    Directory of Open Access Journals (Sweden)

    Colin Jones

    2002-11-01

    Full Text Available Fundamental to the development of new customer value offerings via web-based commerce is a small firm’s ability to strategically acquire and exploit knowledge. The focus of this paper is the empirical testing of a normative web-based commerce adoption model developed from a review of the extant literature related to electronic marketing, the Internet and the diffusion of new innovations. A preliminary test of the model’s theoretical contentions lent support to its overall focus, but found that the firm’s existing learning capabilities were diminished during the adoption of web-based commerce. Consequently, sub-optimal adoption outcomes were associated with insufficient knowledge development.

  3. Client Oriented Approach for Assisting Business Improvement Decision Making

    2014-02-01

    Full Text Available An important aspect of the corporate responsibility towards the customers is to ensure the correct value transfer, through the quality and price of the product/service. By using customer satisfaction in order to measure value and the quality provided to customers, this paper proposes a methodology of assisting management decisions in improving business processes. The proposed techniques and tools, specific to quality management, are used for determining the processes which need to be improved or innovated in order to increase customer satisfaction. Thus, the methodology contributes to the creation of a decision-making framework for an efficient orientation of the resources for maximising the generated value and minimising the costs. In order to illustrate its application, we present a study based on the responses regarding satisfaction elements of 679 companies, the customers of a distribution chain in the field of interior fittings. The research highlights the practical method of determining the priority processes for increasing customer satisfaction, taking into account the satisfaction targets and the nature of the necessary actions in order to maximize the created value and to minimize the costs of these processes.

  4. Framing design research for service orientation through PSS approaches

    DEFF Research Database (Denmark)

    Sakao, Tomohiko; Sandström, Gunilla Ölundh

    2009-01-01

    In order to respond to the industrial trend towards service design and delivery, design research must address a vast area partially related to value creation, marketing and network theories. However, compared to the space to be explored, there is little insight available. Thus, this paper, as a first step, proposes a way to frame such design research. First, an extensive literature review is performed of over 100 articles on not only PSS-design research but also on related research in fields as PSS in general, service design, innovation, and business models in a broad view. Based on the literature analysis, the authors present three crucial dimensions for service oriented design research, i.e. an offer dimension representing products and services, a provider dimension, and a customer/user dimension. In addition, three research targets are proposed; PSS-offer modelling, PSS development, and PSS potential. Furthermore, several promising future research directions are identified. These include evaluating economic consequences or environmental benefits, establishing terminology, organizational issues, and developing methods and tools to support designers. The boundaries to other research fields are getting blurry and many aspects of other professionalisms must be taken into account. Thus, there is especially need in future research to open towards other research areas.

  5. Ultra low power signal oriented approach for wireless health monitoring.

    Marinkovic, Stevan; Popovici, Emanuel

    2012-01-01

    In recent years there is growing pressure on the medical sector to reduce costs while maintaining or even improving the quality of care. A potential solution to this problem is real time and/or remote patient monitoring by using mobile devices. To achieve this, medical sensors with wireless communication, computational and energy harvesting capabilities are networked on, or in, the human body forming what is commonly called a Wireless Body Area Network (WBAN). We present the implementation of a novel Wake Up Receiver (WUR) in the context of standardised wireless protocols, in a signal-oriented WBAN environment and present a novel protocol intended for wireless health monitoring (WhMAC). WhMAC is a TDMA-based protocol with very low power consumption. It utilises WBAN-specific features and a novel ultra low power wake up receiver technology, to achieve flexible and at the same time very low power wireless data transfer of physiological signals. As the main application is in the medical domain, or personal health monitoring, the protocol caters for different types of medical sensors. We define four sensor modes, in which the sensors can transmit data, depending on the sensor type and emergency level. A full power dissipation model is provided for the protocol, with individual hardware and application parameters. Finally, an example application shows the reduction in the power consumption for different data monitoring scenarios. PMID:22969379

  6. Recent developments and object-oriented approach in FTU database

    International Nuclear Information System (INIS)

    During the last two years, the experimental database of Frascati Tokamak Upgrade (FTU) has been changed from several points of view, particularly: (i) the data and the analysis codes have been moved from the IBM main frame to Unix platforms making enabling the users to take advantage of the large quantities of commercial and free software available under Unix (Matlab, IDL, etc); (ii) AFS (Andrew File System) has been chosen as the distributed file system making the data available on all the nodes and distributing the workload; (iii) 'One measure/one file' philosophy (vs. the previous 'one pulse/one file') has been adopted increasing the number of files into the database but, at the same time, allowing the most important data to be available just after the plasma discharge. The client-server architecture has been tested using the signal viewer client jScope. Moreover, an object oriented data model (OODM) of FTU experimental data has been tried: a generalized model in tokamak experimental data has been developed with typical concepts such as abstraction, encapsulation, inheritance, and polymorphism. The model has been integrated with data coming from different databases, building an Object Warehouse to extract, with data mining techniques, meaningful trends and patterns from huge amounts of data

    2000-06-01

    The Very Large Telescope (VLT) Telescope Control Software (TCS) is a portable system. It is now in use or will be used in a whole family of ESO telescopes VLT Unit Telescopes, VLTI Auxiliary Telescopes, NTT, La Silla 3.6, VLT Survey Telescope and Astronomical Site Monitors in Paranal and La Silla). Although it has been developed making extensive usage of Object Oriented (OO) methodologies, the overall development process chosen at the beginning of the project used traditional methods. In order to warranty a longer lifetime to the system (improving documentation and maintainability) and to prepare for future projects, we have introduced a full OO process. We have taken as a basis the United Software Development Process with the Unified Modeling Language (UML) and we have adapted the process to our specific needs. This paper describes how the process has been applied to the VLTI Auxiliary Telescopes Control Software (ATCS). The ATCS is based on the portable VLT TCS, but some subsystems are new or have specific characteristics. The complete process has been applied to the new subsystems, while reused code has been integrated in the UML models. We have used the ATCS on one side to tune the process and train the team members and on the other side to provide a UML and WWW based documentation for the portable VLT TCS.

    The Franco-Italian VIMOS instrument is a VIsible imaging Multi-Object Spectrograph with outstanding multiplex capabilities, allowing to take spectra of more than 800 objects simultaneously, or integral field spectroscopy mode in a 54x54 arcsec area. VIMOS is being installed at the Nasmyth focus of the third Unit Telescope of the European Southern Observatory Very Large Telescope (VLT) at Mount Paranal in Chile. This paper will describe the analysis, the design and the implementation of the VIMOS Instrument Control System, using UML notation. Our Control group followed an Object Oriented software process while keeping in mind the ESO VLT standard control concepts. At ESO VLT a complete software library is available. Rather than applying waterfall lifecycle, ICS project used iterative development, a lifecycle consisting of several iterations. Each iteration consisted in : capture and evaluate the requirements, visual modeling for analysis and design, implementation, test, and deployment. Depending of the project phases, iterations focused more or less on specific activity. The result is an object model (the design model), including use-case realizations. An implementation view and a deployment view complement this product. An extract of VIMOS ICS UML model will be presented and some implementation, integration and test issues will be discussed.

    2006-07-01

    Full Text Available Another approach (Multiple Triangulation Analysis, MTA is presented to determine the orientation of magnetic flux rope, based on 4-point measurements. A 2-D flux rope model is used to examine the accuracy of the MTA technique in a theoretical way. It is found that the precision of the estimated orientation is dependent on both the spacecraft separation and the constellation path relative to the flux rope structure. However, the MTA error range can be shown to be smaller than that of the traditional MVA technique. As an application to real Cluster data, several flux rope events on 26 January 2001 are analyzed using MTA, to obtain their orientations. The results are compared with the ones obtained by several other methods which also yield flux rope orientation. The estimated axis orientations are shown to be fairly close, suggesting the reliability of the MTA method.

  13. Effective-mass approach for n-type semiconductor nanowire MOSFETs arbitrarily oriented

    International Nuclear Information System (INIS)

    A method which calculates the effective masses in arbitrarily oriented semiconductor nanowires is presented. In order to avoid the full three-dimensional (3D) resolution of the Schroedinger equation, the method decouples within a Cartesian system the transport direction from the cross section. Results give the new effective mass expressions for each valley and channel orientation. As a direct application, transport in [100]-oriented Ge nanowire metal-oxide-semiconductor field-effect transistors (MOSFETs) is then studied by using a self-consistent 'mode-space' approach expressed in the nonequilibrium Green's function formalism. Along this wire orientation, we show that the effective masses resulting from our approach are very close to the one obtained using a sp3 tight-binding band-structure calculation for nanowires as thin as 4 nm

    1998-01-01

    An approach. based upon the use of a Kalman filter. that is currently employed at the Jet Propulsion Laboratory (JPL) for combining independent measurements of the Earth's orientation, is presented. Since changes in the Earth's orientation can be described is a randomly excited stochastic process, the uncertainty in our knowledge of the Earth's orientation grows rapidly in the absence of measurements. The Kalman-filter methodology allows for an objective accounting of this uncertainty growth, thereby facilitating the intercomparison of measurements taken at different epochs (not necessarily uniformly spaced in time) and with different precision. As an example of this approach to combining Earth-orientation series, a description is given of a combination, SPACE95, that has been generated recently at JPL.

  15. An object-oriented approach to site characterization decision support

    International Nuclear Information System (INIS)

    Effective decision support for site characterization is key to determining the nature and extent of contamination and the associated human and environmental risks. Site characterization data, however, present particular problems to technical analysts and decision-makers. Such data are four dimensional, incorporating temporal and spatial components. Their sheer volume can be daunting -- sites with hundreds of monitoring wells and thousands of samples sent for laboratory analyses are not uncommon. Data are derived from a variety of sources including laboratory analyses, non-intrusive geophysical surveys, historical information, bore logs, in-field estimates of key physical parameters such as aquifer transmissivity, soil moisture content, depth-to-water table, etc. Ultimately, decisions have to be made based on data that are always incomplete, often confusing, inaccurate, or inappropriate, and occasionally wrong. In response to this challenge, two approaches to environmental decision support have arisen, Data Quality Objectives (DQOS) and the Observational Approach (OA). DQOs establish criteria for data collection by clearly defining the decisions that need to be made, the uncertainty that can be tolerated, and the type and amount of data that needs to be collected to satisfy the uncertainty requirements. In practice, DQOs are typically based on statistical measures. The OA accepts the fact that the process of characterizing and remediating contaminated sites is always uncertain. Decision-making with the OA is based on what is known about a site, with contingencies developed for potential future deviations from the original assumptions about contamination nature, extent, and risks posed

  16. Towards a user-oriented analytical approach to learning design

    2008-12-01

    Full Text Available The London Pedagogy Planner (LPP is a prototype for a collaborative online planning and design tool that supports lecturers in developing, analysing and sharing learning designs. The tool is based on a developing model of the components involved in learning design and the critical relationships between them. As a decision tool it makes the pedagogical design explicit as an output from the process, capturing it for testing, redesign, reuse and adaptation by the originator, or by others. The aim is to test the extent to which we can engage lecturers in reflecting on learning design, and make them part of the educational community that discovers how best to use technology-enhanced learning. This paper describes the development of LPP, presents pedagogical benefits of visual representations of learning designs and proposes an analytical approach to learning design based on these visual representations. The analytical approach is illustrated based on an initial evaluation with a small group of lecturers from two partner institutions.

  19. Information-related complexity: a problem-oriented approach

    CERN Document Server

    Perevalov, Eugene

    2013-01-01

    A general notion of information-related complexity applicable to both natural and man-made systems is proposed. The overall approach is to explicitly consider a rational agent performing a certain task with a quantifiable degree of success. The complexity is defined as the minimum (quasi-)quantity of information that's necessary to complete the task to the given extent -- measured by the corresponding loss. The complexity so defined is shown to generalize the existing notion of statistical complexity when the system in question can be described by a discrete-time stochastic process. The proposed definition also applies, in particular, to optimization and decision making problems under uncertainty in which case it gives the agent a useful measure of the problem's "susceptibility" to additional information and allows for an estimation of the potential value of the latter.

    Full Text Available Grids are emerging as the infrastructure for next generationcomputing. In Grid environments, the resources areheterogeneous and geographically distributed with varyingavailability and a variety of usage and cost policies fordiverse users at different times and, priorities as well asgoals that vary with time. The management of resources insuch a large and distributed environment is a complex task.In this paper a model has been proposed using auctionoriented approach. This auction model allows bidders to bidon various attributes beyond the price. The auctioneerselects winners based on the price as well as on otherattributes. Thus, the overall utility of a deal for the buyermust consider not only the price of the auctioning item, butalso a combination of the different attributes. This model hasalso been implemented.

  1. A collaborative learning approach for service-oriented introductory physics

    Science.gov (United States)

    Smith, Michael R.

    1997-03-01

    I have taught algebra-based introductory physics for six years to liberal arts students. It was primarily a service course for students majoring in Athletic Training, Physical Therapy, Geology, Biology, and Pre-Med. The typical student was characterized by having a minimal math and problem-solving proficiency. There also was a pattern of students being predisposed to memorizing facts and formulas, and attempting to solve problems by finding the correct formula and "plugging in" numbers to get an answer. The students seemed to have a minimal ability in deductive reasoning and problem solving, starting from basic principles. It is no wonder that they entered the introductory physics service course with extreme trepidation, based upon a strongly perceived physics phobia. A standard lecture format was used for the class size of approximately 25-30 students; and an attempt was always made to engage the students through the Socratic approach, by asking leading questions during the course of the lecture. The students were relatively unprepared and couldn't participate in the class, and often responded antagonistically. They indicated they didn't want to be asked to think about an issue, but would rather just be told the facts so they could take specific notes for subsequent memorization. It was clear from the results of the open book exams given during the semester that the majority of students could not approach problem solving using deductive reasoning based on basic principles, but relied on attempting to force-fit the problem into a worked example in the text (often out of context, with illogical results). The absentee rate in the classroom was usually around 30-40%. The academic administration of my liberal arts university has the policy of formal course evaluations by the students at the end of each semester. The evaluation questionnaire appears to be primarily a measurement of the stress level of the student during the course, and the evaluation score I received for the service physics course was typically on the order of 3 out of a possible 5; a score considered unsatisfactory by the administration.

    Teret, Stephen P; Culross, Patti L

    2002-01-01

    Injury prevention experts have suggested that gun manufacturers could reduce youth violence by changing the design of guns. Product safety features could make guns more difficult for children to fire unintentionally and more difficult to use if stolen or obtained illegally. This article gives a brief history of efforts to make safer, smarter guns and assesses the potential of the product safety approach for reducing youth gun violence. Among the article's key findings: Research from the injury prevention field suggests that changing product design may be more effective in preventing injuries than trying to change personal behaviors; Existing product safety technologies for guns could reduce unintentional gun injuries, especially to young children. In addition, emerging technologies will enable gun manufacturers to "personalize" guns, which could prevent unauthorized users of any age from firing the weapons. Personalization could decrease access to guns by adolescents; Gun manufacturers have been slow to incorporate safety features into their products; but legislative, regulatory, and litigation efforts are under way to mandate safer guns. The authors envision a future when the law requires product safety features--including personalization--on all new firearms. These product safety features have the potential to reduce both intentional and unintentional firearm injury and death. PMID:12194606

Its scope covers the processes, models, technologies, people, and knowledge that have the capability to contribute to developing such systems. The paper also relates to contributions of some of Harlan D. Mills award recipients for software engineering achievement, to address the needs to: i improve the engineering education in an academic setting, and ii develop real-life software and system projects. Hybrid educational methods are applied for student learning that combine class room approach of teaching fundamental theoretical concepts and practice via real world complex projects embedding intelligence in software and systems products. System thinking demanded by modern design philosophies is applied to interlink prod-ucts, software, and people. Student groups are developing their projects in an interactive and collaborative manner.

    2014-01-01

    Full Text Available The Sun is responsible for the eruption of billions of tons of plasma andthe generation of near light-speed particles that propagate throughout the solarsystem and beyond. If directed towards Earth, these events can be damaging toour tecnological infrastructure. Hence there is an effort to understand the causeof the eruptive events and how they propagate from Sun to Earth. However, thephysics governing their propagation is not well understood, so there is a need todevelop a theoretical description of their propagation, known as a PropagationModel, in order to predict when they may impact Earth. It is often difficultto define a single propagation model that correctly describes the physics ofsolar eruptive events, and even more difficult to implement models capable ofcatering for all these complexities and to validate them using real observational data.In this paper, we envisage that workflows offer both a theoretical andpractical framerwork for a novel approach to propagation models. We definea mathematical framework that aims at encompassing the different modalitieswith which workflows can be used, and provide a set of generic building blockswritten in the TAVERNA workflow language that users can use to build theirown propagation models. Finally we test both the theoretical model and thecomposite building blocks of the workflow with a real Science Use Case that wasdiscussed during the 4th CDAW (Coordinated Data Analysis Workshop eventheld by the HELIO project. We show that generic workflow building blocks canbe used to construct a propagation model that succesfully describes the transitof solar eruptive events toward Earth and predict a correct Earth-impact time

  5. A Christian educational perspective on the process oriented approach to intrinsic motivation

    Mechaéla Scott

    1992-03-01

    Full Text Available Within the classroom context, albeit school or university, intrinsic motivation can effectively be described and changed if a process-oriented approach is employed. The question is posed whether a process-oriented approach to motivation is acceptable to Christian education. To answer this question, intrinsic motivation and the process-oriented approach to motivation are described. A Christian view of self-knowledge and control, which are the main components of a process-oricnted approach to motivation, is subsequently given and the process-oriented approach to motivation is subjected to a Christian evaluation. The conclusions are drawn that this approach can fruitfully be used in Christian education, given that self-knowledge and control arc interpreted within the context of the concept of the student as God’s representative on earth and the fact that God equipped him adequately with cognitive, affective and conative abilities to respond to His call to discover, develop and rule the earth actively.

  8. Crosscutting Specification Interference Detection at Aspect Oriented UML-Based Models: A Database Approach

    Directory of Open Access Journals (Sweden)

    Ahmed Sharaf Eldin

    2014-08-01

    Full Text Available In aspect oriented development, obliviousness is one of its pillars as it helps developers to implement crosscutting concerns via aspects, which increases the overall software modularity. Despite of its merits, obliviousness brings the problem of interferences among aspects as several aspects pointcuts may address the same joinpoint for the same advice. Existing approaches deals with conflicts at design level use graphs structures, which increase in size as project size increases. In this work, a relational database model is used to map aspect oriented design models and then conflicts are extracted by an algorithm runs over this database. This approach is simpler than other approaches and enables large project sizes while the other approaches get complicated due to increment in graph size. The proposed approach can be extended to the distributed team development, dependent on the database engine used.

    Pimenta, Fernando; Tirapicos, Luís; Smith, Andrew

    2009-12-01

    In this work we have conducted a study on the orientations in the landscape of twelve megalithic enclosures in the Alentejo region of southern Portugal. Some of these sites date back to the sixth or fifth millennium B.C. and are among the oldest stone enclosures in Europe. The results of the survey show a pattern toward eastern rising orientations. We used dedicated GIS software from one of the authors to produce horizon profiles and applied a statistical Bayesian approach in an attempt to check how the data would fit to different models. In particular, we tested our results for a possible ritual interest in the Autumn or Harvest Full Moon and discuss previous studies by Michael Hoskin and colleges on the orientations of seven stone dolmens of this area that have shown the existence of a possible custom for an orientation toward the sunrise.

    Diniz, Pedro; Coutinho, José; Petrov, Zlatko

    2013-01-01

    This book provides techniques to tackle the design challenges raised by the increasing diversity and complexity of emerging, heterogeneous architectures for embedded systems. It describes an approach based on techniques from software engineering called aspect-oriented programming, which allow designers to control today’s sophisticated design tool chains, while maintaining a single application source code.  Readers are introduced to the basic concepts of an aspect-oriented, domain specific language that enables control of a wide range of compilation and synthesis tools in the partitioning and mapping of an application to a heterogeneous (and possibly multi-core) target architecture.  Several examples are presented that illustrate the benefits of the approach developed for applications from avionics and digital signal processing. Using the aspect-oriented programming techniques presented in this book, developers can reuse extensive sections of their designs, while preserving the original application source-...

    2015-06-01

    African American youth, particularly those from single-mother homes, are overrepresented in statistics on externalizing problems. The family is a central context in which to understand externalizing problems; however, reliance on variable-oriented approaches to the study of parenting, which originate from work with intact, middle-income, European American families, may obscure important information regarding variability in parenting styles among African American single mothers, and in turn, variability in youth outcomes as well. The current study demonstrated that within African American single-mother families: (a) a person-, rather than variable-, oriented approach to measuring parenting style may further elucidate variability; (b) socioeconomic status may provide 1 context within which to understanding variability in parenting style; and (c) 1 marker of socioeconomic status, income, and parenting style may each explain variability in youth externalizing problems; however, the interaction between income and parenting style was not significant. Findings have potential implications for better understanding the specific contexts in which externalizing problems may be most likely to occur within this at-risk and underserved group.

    2015-01-01

    Getting a land vehicle's accurate position, azimuth and attitude rapidly is significant for vehicle based weapons' combat effectiveness. In this paper, a new approach to acquire vehicle's accurate position and orientation is proposed. It uses biaxial optical detection platform (BODP) to aim at and lock in no less than three pre-set cooperative targets, whose accurate positions are measured beforehand. Then, it calculates the vehicle's accurate position, azimuth and attitudes by the rough position and orientation provided by vehicle based navigation systems and no less than three couples of azimuth and pitch angles measured by BODP. The proposed approach does not depend on Global Navigation Satellite System (GNSS), thus it is autonomous and difficult to interfere. Meanwhile, it only needs a rough position and orientation as algorithm's iterative initial value, consequently, it does not have high performance requirement for Inertial Navigation System (INS), odometer and other vehicle based navigation systems, even in high precise applications. This paper described the system's working procedure, presented theoretical deviation of the algorithm, and then verified its effectiveness through simulation and vehicle experiments. The simulation and experimental results indicate that the proposed approach can achieve positioning and orientation accuracy of 0.2 m and 20? respectively in less than 3 min. PMID:26492249

    1996-11-01

    Full Text Available The paper describes a pattern-oriented approach to evaluate modeling methods and to compare various methods with each other from a methodical viewpoint. A specific set of principles (the patterns is defined by investigating the notations and the documentation of comparable modeling methods. Each principle helps to examine some parts of the methods from a specific point of view. All principles together lead to an overall picture of the method under examination. First the core ("method neutral" meaning of each principle is described. Then the methods are examined regarding the principle. Afterwards the method specific interpretations are compared with each other and with the core meaning of the principle. By this procedure, the strengths and weaknesses of modeling methods regarding methodical aspects are identified. The principles are described uniformly using a principle description template according to descriptions of object oriented design patterns. The approach is demonstrated by evaluating a business process modeling method.

  6. A new approach to texture measurements: Orientation distribution function (ODF) determination by Rietveld refinement

    Energy Technology Data Exchange (ETDEWEB)

    Vondreele, R.; Larson, A.; Lawson, A.; Sheldon, R.; Wright, S.

    1996-09-01

    The preferred orientation of crystal grains within a manufactured part is described most fully by its orientation distribution function (ODF), which is a mapping of the probability of each of the possible grain orientations with respect to the exterior dimensions. Traditionally, an ODF is determined from pole figures for a relatively small number of reflections. These pole figures are measured with x-rays or neutrons using short detector scans over the center of an individual diffraction peak for a large number of different sample orientations. This is efficient if the selected diffraction peaks are reasonably strong (relative to background) and well separated, such as in pure fcc and bcc metals. It is also appropriate for constant wavelength sources where collection of individual diffraction peak intensities is a reasonably efficient use of the source. However, the traditional method is not very efficient for neutron diffraction at a spallation source such as LANSCE where the entire diffraction pattern is accessible for each sample setting. Moreover, a different approach is necessary for complicated diffraction patterns, such as from composite materials, intermetallic compounds, high {Tc} ceramics, polyphasic minerals and polymers where there is expected to be heavy overlap of adjacent diffraction peaks. In addition, the large number of settings normally collected for an individual pole figure may not be necessary, since the entire pattern is obtained at each setting. Thus, a new method of ODF analysis needs to be developed to handle the more complex diffraction patterns obtained from modern technological materials as well as take advantage of the particular characteristics of spallation neutron sources. This project sought to develop the experimental procedures and the mathematical treatment needed to produce an orientation distribution function (ODF) directly from full diffraction patterns from a sample in a limited number of orientations.

  9. Combined object-oriented approach for development of process control systems

    International Nuclear Information System (INIS)

    Full text: The traditional approaches for development of software control system in automation an information technology based on a directly code creation are no longer effective and successful enough. The response to these challenges is the Model Driven Engineering (MDE) or its counter part in the field of architectures Model Driven Architecture (MDA). One of the most promising approach supporting MDE and MDA is UML. It does not specify a methodology for software or system design but aims to provide an integrated modeling framework for structural, functional and behavior descriptions. The success of UML in many object-oriented approaches led to an idea of applying UML to design of multi agent systems. The approach proposed in this paper applies modified Harmony methodology and is based on the combined use of UML profile for system engineering, IEC61499 standard and FIPA standard protocols. The benefits of object-oriented paradigm and the models of IEC61499 standard are extended with UML/SysML and FIPA notations. The development phases are illustrated with the UML models of a simple process control system. The main benefits of using the proposed approach can be summarized as: it provides consistency in the syntax and underlying semantics; increases the potential and likelihood of reuse; supports the whole software development life cycle in the field of process control. Including the SysML features, based on extended activity and parametric diagrams, flow ports and items to the proposed approach opens the possibilities for modeling of continuous system and support the development in field of process control. Another advantage, connected to the UML/MARTE profile is the possibility for analysis of the designed system and detailed design of the hardware and software platform of the modeled application. Key words: object-oriented modeling, control system, UML, SysML, IEC 61499

  11. A Sequence of Assignments to Teach Object-Oriented Programming: a Constructivism Design-First Approach

    Directory of Open Access Journals (Sweden)

    Kleanthis C. THRAMBOULIDIS

    2003-04-01

    Full Text Available A constructivism-based approach to teach the object-oriented (OO programming paradigm in introductory computer courses was developed and used for several years. A multi-entity system from every-day life was adopted, to exploit the novice programmer's existing knowledge and build on it the OO conceptual framework. A sequence of assignments has been designed and developed to allow students exposed to this approach to experiment with Java programming and see how the OO conceptual framework is implemented. In this paper, this sequence of assignments is presented, discussed and evaluated in the context of the defined approach. The set of assignments that is based on a software-engineering-centered view and more precisely on a design-first approach, comes with the description of the strategy and graded hints that lead students to the final solution. Although it was first implemented as supplementary material, it quickly became the core component of the course.

    2014-03-01

    Civil applications for small size unmanned aerial vehicles (UAV) have become quite important in recent years and so have accurate orientation and navigation of these devices in unknown terrain. In this work we focus on on-line compatible positioning in facade observation based on monocular low resolution still images acquired by a camera mounted on a UAV. Also, a 3D point cloud of the facade is generated. This allows further processing steps, e.g. navigation assistance, collision avoidance or the evaluation of the point cloud density, verifying completeness of the data. To be able to deal with the increasing amount of observations and unknown parameters we implement an incremental bundle adjustment based on automatically determined tie points and sliding image triplets. The tripletwise orientation allows for an efficient double cross-check of the detected feature points and hence guarantees reliable initial values for the nonlinear bundle adjustment. The initial values are estimated within a convex formulation delivering a sound basis for the incremental adjustment. Our algorithm is evaluated by means of imagery we took of the facade of the Welfenschloss in Hannover, captured from a manually flown Microdrones md4-200 micro-UAV.We compare the orientation results of our approach with an approach in which initial values for the unknown object coordinates are computed algebraically.

  16. The Pedagogical Orientations of South African Physical Sciences Teachers Towards Inquiry or Direct Instructional Approaches

    Science.gov (United States)

    Ramnarain, Umesh; Schuster, David

    2014-08-01

    In recent years, inquiry-based science instruction has become widely advocated in science education standards in many countries and, hence, in teacher preparation programmes. Nevertheless, in practice, one finds a wide variety of science instructional approaches. In South Africa, as in many countries, there is also a great disparity in school demographic situations, which can also affect teaching practices. This study investigated the pedagogical orientations of in-service physical sciences teachers at a diversity of schools in South Africa. Assessment items in a Pedagogy of Science Teaching Test (POSTT) were used to identify teachers' science teaching orientations, and reasons for pedagogical choices were probed in interviews. The findings reveal remarkable differences between the orientations of teachers at disadvantaged township schools and teachers at more privileged suburban schools. We found that teachers at township schools have a strong `active direct' teaching orientation overall, involving direct exposition of the science followed by confirmatory practical work, while teachers at suburban schools exhibit a guided inquiry orientation, with concepts being developed via a guided exploration phase. The study identified contextual factors such as class size, availability of resources, teacher competence and confidence, time constraints, student ability, school culture and parents' expectations as influencing the methods adopted by teachers. In view of the recent imperative for inquiry-based learning in the new South African curriculum, this study affirms the context specificity of curriculum implementation (Bybee 1993) and suggests situational factors beyond the curriculum mandate that need to be addressed to achieve successful inquiry-based classroom instruction in science.

    Full Text Available Object oriented design is becoming more popular in software development and object oriented design metrics which is an essential part of software environment. The main goal in this paper is to predict factors of MOOD method for OO using a statistical approach. Therefore, linear regression model is used to find the relationship between factors of MOOD method and their influences on OO software measurements. Fortunately, through this process a prediction could be made for the line of code (LOC, number of classes (NOC, number of methods (NOM, and number of attributes (NOA. These measurements permit designers to access the software early in process, making changes that will reduce complexity and improve the continuing capability of the design.

Unless we monitor a system, we cannot tools. Due to the heterogeneous nature of the hope to manage and control its performance. In this underlying systems at NASA Langley Research Center, paper, we describe a network monitoring system that we use an object-oriented approach for the design, we are currently designing and implementing. Keeping, first, we use UML (Unified Modeling Language) to in mind the complexity of the task and the required model users' requirements. Second, we identify the flexibility for future changes, we use an object-oriented existing capabilities of the underlying monitoring design methodology. The system is built using the system.

Knowledge engineers capture expert knowledge and encode it as a set of rules for automating the expert’s reasoning process to solve problems in a variety of domains. We describe the development of a knowledge-based system approach to enhance program comprehension of Service Oriented Architecture (SOA software. Our approach uses rule-based methods to automate the analysis of the set of artifacts involved in building and deploying a SOA composite application. The rules codify expert knowledge to abstract information from these artifacts to facilitate program comprehension and thus assist Software Engineers as they perform system maintenance activities. A main advantage of the knowledge-based approach is its adaptability to the heterogeneous and dynamically evolving nature of SOA environments.

    Empirical evidence supporting frame-of-reference (FOR) training as an effective intervention for calibrating raters is convincing. Yet very little is known about who does better or worse in FOR training. We conducted a field study of how motivational factors influence affective, cognitive, and behavioral learning outcomes, as well as near transfer indexed by achieving professional certification. Relying on goal orientation theory, we hypothesized effects for 3 goal orientations: learning, prove performance, and avoid performance. Results were generally supportive across learning outcomes and transfer. Findings further supported a hypothesized interaction between learning self-efficacy and avoid performance goal orientation, such that higher levels of learning self-efficacy mitigated the negative effects of higher performance avoid tendencies.

    Full Text Available To communicate is the primary goal of most foreign language learning (EFL. As an important component of the four macro skills (listening, speaking, reading and writing, reading should also serve this purpose. However, traditional methodology still dominates extensive reading teaching in most of the universities. To promote a communicative extensive reading class, we may start by designing various tasks and activities. This paper introduces a task-oriented approach in English extensive reading class. According to Nunan, task-oriented teaching involves learners in the classroom to comprehend, manipulate, produce or interact in the target language, but the focus is on the meaning rather than the form. In light of psycholinguistic model and schema theory model, the methodology covers information-gap activity, opinion-gap activity and reasoning-gap activity which can be run in the class. The task-approaches make the interaction between teacher and students, students and students more active and meaningful. Skills of reading to solve communicative problems are always treated consciously. This approach may hopefully result in some improvement on the teaching of English reading.

  8. Artist Agent: A Reinforcement Learning Approach to Automatic Stroke Generation in Oriental Ink Painting

    Science.gov (United States)

    Xie, Ning; Hachiya, Hirotaka; Sugiyama, Masashi

    Oriental ink painting, called Sumi-e, is one of the most appealing painting styles that has attracted artists around the world. Major challenges in computer-based Sumi-e simulation are to abstract complex scene information and draw smooth and natural brush strokes. To automatically find such strokes, we propose to model the brush as a reinforcement learning agent, and learn desired brush-trajectories by maximizing the sum of rewards in the policy search framework. We also provide elaborate design of actions, states, and rewards tailored for a Sumi-e agent. The effectiveness of our proposed approach is demonstrated through simulated Sumi-e experiments.

    Science.gov (United States)

    Ehrich, Hans-Dieter

    1994-12-01

    A survey of concepts for an information system specification is given, based on the viewpoint that an information system is a community of interacting objects. Objects are self-contained units of structure and behavior capable of operating independently and cooperating concurrently. The approach integrates concepts from semantic data modeling and concurrent processes, adopting structuring principles partly developed in the framework of object-orientation and partly in that of abstract data types. The languages OBLOG and TROLL are based on these concepts and their use is illustrated by examples.

    1985-01-01

    This paper presents a conceptual approach for leading various types of groups of chronically mentally ill patients. Although these groups may have a concrete, task-oriented purpose, with skillful leadership they also function as psychotherapy groups. The developmental deficits in ego functions, object relations, and social skills that severely impair such groups can be compensated by non-interpretative actions of the therapists. The group leader must actively work to provide for the structure, stability, and safety of the group when group members are unable to provide these for themselves. PMID:4049917

  15. An Evaluation of Maintainability of Aspect-Oriented Systems: a Practical Approach

    Directory of Open Access Journals (Sweden)

    2007-06-01

    Full Text Available Maintenance of software systems is becoming major concern for software developers and users. In software projects/products, where software changes/updates are frequently required to improve software quality, maintainability is an important characteristic of ISO 9126 quality standard to evaluate. Analyzability, changeability, stability, and testability are sub attributes/characteristics of maintainability in ISO 9126. In this paper, changeability is measured by making changes at code level of an Aspect- Oriented (AO system. The approach taken to evaluate the changeability of an AO system is to compute the impact of changes made to modules of the system. Some projects1 in aspect-oriented programming (AOP language, AspectJ, have been taken for testing. The results suggest that the AO system can easily absorb changes and AO design metrics can be used as indicators of changeability as well as of maintainability. The results also suggest that a code level change in AO systems not always cause less change impact to other modules than a code level change in Object-Oriented (OO systems.

    No single or combinatorial therapeutic approach has proven effective in decreasing morbidity or engendering a cure of metastatic cancer. In principle, conditionally replication-competent adenoviruses that induce tumor oncolysis through cancer-specific replication hold promise for cancer therapy. However, a single-agent approach may not be adequate to completely eradicate cancer in a patient because most cancers arise from abnormalities in multiple genetic and signal transduction pathways and targeting disseminated metastases is difficult to achieve. Based on these considerations, a novel class of cancer destroying adenoviruses have been produced, cancer terminator viruses (CTVs), in which cancer-specific replication is controlled by the progression-elevated gene-3 promoter and replicating viruses produce a second transgene encoding an apoptosis-inducing and immunomodulatory cytokine, either melanoma differentiation-associated gene-7/interleukin-24 (mda-7/IL-24) or interferon-?. This review focuses on these viruses and ways to improve their delivery systemically and enhance their therapeutic efficacy. PMID:23021240

    2012-07-01

    Full Text Available Nowadays, with the emergence and the evolution of new technologies, such as e-business, a large number of companies are connected to Internet, and have proposed web services to trade. Web services as presented, are conceptually limited components to relatively simple functionalities. Generally, a single service does not satisfy the users needs that are more and more complex. Therefore, services must be made able to be composed to offer added value services. In this paper, a web services composition approach, modelled by Objects-Oriented Petri nets, is presented. In his context, an expressive algebra, which successfully solves the web services complex composition problem, is proposed. A java tool that allows automating this approach; based on a definite algebra and a G-nets meta-model, proposed by us, is developed.

    2002-01-01

    Full Text Available For the rapid progress of Internet technologies in recent years, Electronic Commerce (EC has gained attention as a major theme for enterprises to keep their competitiveness. From the perspective of effective resources utilization, it becomes now an important group for an enterprise to promote its performance and competitiveness through integrating itself and relevant suppliers and consumer as a virtual goal to achieve the so-called Business-to- Business EC. In this paper, we propose an object-oriented modeling approach that addresses the management of collaboration on the Internet between enterprises. The approach divides those required mechanisms for collaboration management into three layers: commitment, role, and activity ones. With this architecture, two enterprises may collaborate via the establishment and maintenance of commitment, the collaboration and coordination between roles and the interaction and coordination between activities. For specification, an object-oriented model is presented for each layer that describes the working details of that layer. To illustrate, these models are applied in a simplified supply chain management among various enterprises.

    With the improvement of remote sensing technology, the spatial, structural and texture information of land covers are present clearly in high resolution imagery, which enhances the ability of crop mapping. Since the satellite RapidEye was launched in 2009, high resolution multispectral imagery together with wide red edge band has been utilized in vegetation monitoring. Broad red edge band related vegetation indices improved land use classification and vegetation studies. RapidEye high resolution imagery acquired on May 29 and August 9th of 2012 was used in this study to evaluate the potential of red edge band in agricultural land cover/use mapping using an objected-oriented classification approach. A new object-oriented decision tree classifier was introduced in this study to map agricultural lands in the study area. Besides the five bands of RapidEye image, the vegetation indexes derived from spectral bands and the structural and texture features are utilized as inputs for agricultural land cover/use mapping in the study. The optimization of input features for classification by reducing redundant information improves the mapping precision over 9% for AdaTree. WL, and 5% for SVM, the accuracy is over 90% for both approaches. Time phase characteristic is much important in different agricultural lands, and it improves the classification accuracy 7% for AdaTree.WL and 6% for SVM.

    Regarding the shortage and deficiency of traditional lake pollution control engineering techniques, a new lake pollution control engineering approach was proposed in this study, based on object-oriented intelligent design (OOID) from the perspective of intelligence. It can provide a new methodology and framework for effectively controlling lake pollution and improving water quality. The differences between the traditional engineering techniques and the OOID approach were compared. The key points for OOID were described as object perspective, cause and effect foundation, set points into surface, and temporal and spatial optimization. The blue algae control in lake was taken as an example in this study. The effect of algae control and water quality improvement were analyzed in details from the perspective of object-oriented intelligent design based on two engineering techniques (vertical hydrodynamic mixer and pumping algaecide recharge). The modeling results showed that the traditional engineering design paradigm cannot provide scientific and effective guidance for engineering design and decision-making regarding lake pollution. Intelligent design approach is based on the object perspective and quantitative causal analysis in this case. This approach identified that the efficiency of mixers was much higher than pumps in achieving the goal of low to moderate water quality improvement. However, when the objective of water quality exceeded a certain value (such as the control objective of peak Chla concentration exceeded 100 microg x L(-1) in this experimental water), the mixer cannot achieve this goal. The pump technique can achieve the goal but with higher cost. The efficiency of combining the two techniques was higher than using one of the two techniques alone. Moreover, the quantitative scale control of the two engineering techniques has a significant impact on the actual project benefits and costs. PMID:23745391

  4. Goal-oriented failure analysis - a systems analysis approach to hazard identification

    International Nuclear Information System (INIS)

    Goal-Oriented Failure Analysis, GOFA, is a methodology which is being developed to identify and analyse the potential failure modes of a hazardous plant or process. The technique will adopt a structured top-down approach, with a particular failure goal being systematically analysed. A systems analysis approach is used, with the analysis being organised around a systems diagram of the plant or process under study. GOFA will also use checklists to supplement the analysis -these checklists will be prepared in advance of a group session and will help to guide the analysis and avoid unnecessary time being spent on identifying obvious failure modes or failing to identify certain hazards or failures. GOFA is being developed with the aim of providing a hazard identification methodology which is more efficient and stimulating than the conventional approach to HAZOP. The top-down approach should ensure that the analysis is more focused and the use of a systems diagram will help to pull the analysis together at an early stage whilst also helping to structure the sessions in a more stimulating way than the conventional techniques. GOFA will be, essentially, an extension of the HAZOP methodology. GOFA is currently being computerised using a knowledge-based systems approach for implementation. The Goldworks II expert systems development tool is being used. (author)

    Magnetic and inertial measurement units are an emerging technology to obtain 3D orientation of body segments in human movement analysis. In this respect, sensor fusion is used to limit the drift errors resulting from the gyroscope data integration by exploiting accelerometer and magnetic aiding sensors. The present study aims at investigating the effectiveness of sensor fusion methods under different experimental conditions. Manual and locomotion tasks, differing in time duration, measurement volume, presence/absence of static phases, and out-of-plane movements, were performed by six subjects, and recorded by one unit located on the forearm or the lower trunk, respectively. Two sensor fusion methods, representative of the stochastic (Extended Kalman Filter) and complementary (Non-linear observer) filtering, were selected, and their accuracy was assessed in terms of attitude (pitch and roll angles) and heading (yaw angle) errors using stereophotogrammetric data as a reference. The sensor fusion approaches provided significantly more accurate results than gyroscope data integration. Accuracy improved mostly for heading and when the movement exhibited stationary phases, evenly distributed 3D rotations, it occurred in a small volume, and its duration was greater than approximately 20 s. These results were independent from the specific sensor fusion method used. Practice guidelines for improving the outcome accuracy are provided. PMID:25302810

  8. A Fuzzy Approach for Integrated Measure of Object-Oriented Software Testability

    2005-01-01

    Full Text Available For large software systems, testing phase seems to have profound effect on the overall acceptability and quality of the final product. The success of this activity can be judged by measuring the testability of the software. A good measure for testability can better manage the testing effort and time. Different Object Oriented Metrics are used in measurement of object-oriented testability but none of them is alone sufficient to give an overall reflection of software testability. Thus an integrated measure considering the effect of all these measures is required to well define the testability. The paper combines OO software metric values into a single overall value (called Testability Index that can be used to calculate the testability of a class. The approach uses fuzzy techniques and concepts (fuzzification of crisp metric values, inference and aggregation, defuzzification of fuzzy output. We include empirical data of testing time of 25 different Java classes, which proves that individual metric values are not sufficient to arrive at the testability of a class and validates the testability index as a good integrated measure for arriving at the testability of the class.

  11. Development of novel control strategies for single-stage autotrophic nitrogen removal: A process oriented approach

    DEFF Research Database (Denmark)

    Vangsgaard, Anna Katrine; Mauricio Iglesias, Miguel

    2014-01-01

    The autotrophic nitrogen removing granular sludge process is a novel and intensified process. However, its stable operation and control remain a challenging issue. In this contribution, a process oriented approach was used to develop, evaluate and benchmark novel control strategies to ensure stable operation and rejection of disturbances. Three novel control strategies were developed, evaluated, and benchmarked against each other: a feedforward control (control structure 1 – CS#1), a rule-based feedback control (CS#2), and a feedforward–feedback controller, in which the feedback loop updates the set point of the feedforward loop (CS#3). The CS#1 gave the best performance against disturbances in the ammonium concentration, whereas the CS#2 provided the best performance against disturbances in the organic carbon concentration and dynamic influent conditions. The CS#3 rejected both disturbances satisfactorily. Thus, the appropriate design will depend on the specific disturbances in the influent generated in the upstream units of the wastewater treatment plant.

    Full Text Available With human capital being critical to corporate success, aligning individual training with business priorities, emerges as a key challenge. Business process oriented learning unites corporate training and business process management. This entails integrating learning into daily working tasks and putting in place mechanisms for the effective management of business processes, organisational roles, competencies and learning processes, to reduce the time to fill competency gaps and to build proficiency according to evolving business needs. In this paper we outline the main characteristics of the PROLIX approach for business-driven training and provide a practical example of how this concept can help a typical vehicle manufacturer effectively resolve competency related business problems stemming from changes in supply chain management.

    Objective To examine whether a change in the approach to management of persistent patent ductus arteriosus (PDA), from “early ligation” to “selective ligation,” is associated with an increased risk of abnormal neurodevelopmental outcome. Study design In 2005, we changed our PDA treatment protocol (in infants ?27 6/7 weeks gestation) from an “early ligation” approach, with PDA ligation quickly if they failed to close after indomethacin (Period 1: 1/99–12/04), to a “selective ligation” approach, with PDA ligation only if specific criteria were met (Period 2: 1/05–5/09). All infants in both periods received prophylactic indomethacin. Multivariate analysis was used to compare the odds of a composite Abnormal Neurodevelopmental Outcome (Bayley MDI or Cognitive score <70, cerebral palsy, blindness, and/or deafness) associated with each treatment approach at 18–36 months (n=224). Results During Period 1, 23% of the infants in follow-up failed indomethacin treatment, and all were ligated; during Period 2, 30% of infants failed indomethacin, and 66% were ligated after meeting pre-specified criteria. Infants treated with the “selective ligation” strategy had fewer Abnormal Outcomes than infants treated with the “early ligation” approach (OR=0.07, p=0.046). Infants ligated before 10 days of age had an increased incidence of Abnormal Neurodevelopmental Outcome. The significant difference in outcomes between the two PDA treatment strategies could be accounted for, in part, by the earlier age of ligation during Period 1. Conclusions A “selective ligation” approach for PDAs that fail to close with indomethacin does not worsen neurodevelopmental outcome at 18–36 months. PMID:22795222

    This study presents a fuzzy multi-criteria decision making (FMCDM) approach for analyzing the influential factors affecting the outcome/success of global software development (GSD) projects. The main aim of this study is to demonstrate the potential of proposed methodology based on FMCDM which is used to measure the offshore/onsite teams' partnership quality dimensions and underlying the influential factors towards the outcome of GSD projects. The uncertainty and subjective vagueness within the decision making process are dealing with fuzzy linguistic terms quantified in an interval scale [0,1]. The proposed FMDCM framework is used to determine the priority weights of partnership quality factors and rating the GSD project outcome/success from the service provider perspective into three dimensions: service quality, schedule and cost improvement. The predicted GSD project outcome values are obtained to facilitate organization and to determine the impact of offshore/on-site teams' partnership quality towards success of GSD project outcome otherwise initiate actions to improve the GSD project outcome. This study established survey research method that involves thirty-eight critical influential factors evaluated by twenty software professionals for their assessment of GSD projects outcome in India.

    The field of Virtual Reality (VR) is diverse, ranging in scope from research into fundamental enabling technologies to the building of full-scale entertainment facilities. However, the concept of virtual reality means many things to many people. Ideally, a definition of VR should derive from how it can provide solutions to existing challenges in building advanced human computer interfaces. The measure of success for VR lies in its ability to enhance the assimilation of complex information, whether to aid in difficult decision making processes, or to recreate real experiences in a compelling way. This philosophy is described using an example from a VR-based advertising project. The common and unique elements of this example are explained, though the fundamental development process is the same for all virtual environments that support information transfer. In short, this development approach is an applications oriented approach that begins by establishing and prioritizing user requirements and seeks to add value to the information transfer process through the appropriate use of VR technology.

    2005-01-01

    There appears to be a lack of evidence concerning the effect of rehabilitation programmes for the long-term sick. More focus in this area would supplement an approach that has been directed toward process evaluation of rehabilitation programmes. It was the purpose of this study to shed light on individual factors and health care and social welfare-related factors, which play a role for the outcome of rehabilitation programmes. In connection with a participatory, action-oriented outpatient rehabilitation program, a questionnaire survey was performed among the programmes participants ("clients"). Questionnaires were completed before the rehabilitation programme's start, at the end of the 8-week programme, and at the 9-months follow-up. Among 389 clients, 271 (69.7%) participated in the study at baseline as well at the 9-months follow-up. The majority of 212 participants were on sick leave--6.6% for more than 1 year. The remainder had been transferred to receiving social benefits after having exceeded the time limit for being sick-listed. A plan of action for active rehabilitation, which was made at the end of the 8-week rehabilitation programme, was only poorly fulfilled after 9 months, 48% were still on sick leave or social benefits at this time. Individual background variables, as well as psychological well-being, mental health, pain level, and pain coping, seemed to have little effect on the outcome of rehabilitation, whilst clients' own evaluations of competence and ability of the involved health care professionals were found important for a positive outcome of the programme. Especially stable relations to a single General Practitioner (GP), who took good care of the patient in the form of giving good information about health and social possibilities, and an empathic attitude toward these hard-pressed clients, were important factors. The odds ratio for a nonbeneficial outcome of the rehabilitation programme, among those who had changed GP and reported poor case treatment by the GP, was 3.9 (95% CI; 1.3-11.9). Additional findings were an association between a desire to go on early retirement pension, higher age, and self-estimated poorer health at baseline, and actual status as pensioner 9 months after the programme. Predictors of a beneficial outcome from the 8-week rehabilitation programme included good and comprehensive care-taking in particular by the clients' GP. The presence of a high level of symptoms and complaints of pain and stress had no effect on the outcome of rehabilitation in this cohort.

    In the recent past both the CCD camera controller hardware and software have witnessed a dynamic change to keep pace with the astronomer's imaging requirements. Conventional data acquisition software is based on menu driven programs developed using structured high level languages in non-window environment. An application under windows offers several advantages to the users, over the non-window approach, like multitasking, accessing large memory and inter-application communication. Windows also provides many programming facilities to the developers such as device-independent graphics, support to wide range of input/output devices, menus, icons, bitmaps. However, programming for windows environment under structured programming demands an in-depth knowledge of events, formats, handles and inner workings. Object-oriented approach simplifies the task of programming for windows by using object windows which manage the message- processing behavior and insulate the developer from the details of inner workings of windows. As a result, a window application can be developed in much less time and effort compared to conventional approaches. We have designed and developed an easy-to-use CCD data acquisition and processing software under Microsoft Windows 3.1 operating environment using object-Pascal for windows. The acquisition software exploits the advantages of the objects to provide custom specific tool boxes to implement different functions of CCD data accusation and image processing. In this paper the hierarchy of the software structure and various application functions are presented. The flexibility of the software to handle different CCDs and also mosaic arrangement is illustrated.

  4. A problem-oriented approach to understanding adaptation: lessons learnt from Alpine Shire, Victoria Australia.

    Climate change is gaining attention as a significant strategic issue for localities that rely on their business sectors for economic viability. For businesses in the tourism sector, considerable research effort has sought to characterise the vulnerability to the likely impacts of future climate change through scenarios or ‘end-point' approaches (Kelly & Adger, 2000). Whilst useful, there are few demonstrable case studies that complement such work with a ‘start-point' approach that seeks to explore contextual vulnerability (O'Brien et al., 2007). This broader approach is inclusive of climate change as a process operating within a biophysical system and allows recognition of the complex interactions that occur in the coupled human-environmental system. A problem-oriented and interdisciplinary approach was employed at Alpine Shire, in northeast Victoria Australia, to explore the concept of contextual vulnerability and adaptability to stressors that include, but are not limited to climatic change. Using a policy sciences approach, the objective was to identify factors that influence existing vulnerabilities and that might consequently act as barriers to effective adaptation for the Shire's business community involved in the tourism sector. Analyses of results suggest that many threats, including the effects climate change, compete for the resources, strategy and direction of local tourism management bodies. Further analysis of conditioning factors revealed that many complex and interacting factors define the vulnerability and adaptive capacity of the Shire's tourism sector to the challenges of global change, which collectively have more immediate implications for policy and planning than long-term future climate change scenarios. An approximation of the common interest, i.e. enhancing capacity in business acumen amongst tourism operators, would facilitate adaptability and sustainability through the enhancement of social capital in this business community.

    AMBIT (Adolescent Mentalization-Based Integrative Treatment) is a developing team approach to working with hard-to-reach adolescents. The approach applies the principle of mentalization to relationships with clients, team relationships and working across agencies. It places a high priority on the need for locally developed evidence-based practice, and proposes that outcome evaluation needs to be explicitly linked with processes of team learning using a learning organization framework. A number of innovative methods of team learning are incorporated into the AMBIT approach, particularly a system of web-based wiki-formatted AMBIT manuals individualized for each participating team. The paper describes early development work of the model and illustrates ways of establishing explicit links between outcome evaluation, team learning and manualization by describing these methods as applied to two AMBIT-trained teams; one team working with young people on the edge of care (AMASS - the Adolescent Multi-Agency Support Service) and another working with substance use (CASUS - Child and Adolescent Substance Use Service in Cambridgeshire). Measurement of the primary outcomes for each team (which were generally very positive) facilitated team learning and adaptations of methods of practice that were consolidated through manualization.

    Predictions of patient outcomes after a given therapy are fundamental to medical practice. We employ a machine learning approach towards predicting the outcomes after stereotactic radiosurgery for cerebral arteriovenous malformations (AVMs). Using three prospective databases, a machine learning approach of feature engineering and model optimization was implemented to create the most accurate predictor of AVM outcomes. Existing prognostic systems were scored for purposes of comparison. The final predictor was secondarily validated on an independent site's dataset not utilized for initial construction. Out of 1,810 patients, 1,674 to 1,291 patients depending upon time threshold, with 23 features were included for analysis and divided into training and validation sets. The best predictor had an average area under the curve (AUC) of 0.71 compared to existing clinical systems of 0.63 across all time points. On the heldout dataset, the predictor had an accuracy of around 0.74 at across all time thresholds with a specificity and sensitivity of 62% and 85% respectively. This machine learning approach was able to provide the best possible predictions of AVM radiosurgery outcomes of any method to date, identify a novel radiobiological feature (3D surface dose), and demonstrate a paradigm for further development of prognostic tools in medical care.

    2013-02-01

    Virtual reality and augmented reality environments using helmet-mounted displays create a sense of immersion by closely coupling user head motion to display content. Delays in the presentation of visual information can destroy the sense of presence in the simulation environment when it causes a lag in the display response to user head motion. The effect of display lag can be minimized by predicting head orientation, allowing the system to have sufficient time to counteract the delay. In this paper, anew head orientation prediction technique is proposed that uses a multiple delta quaternion (DQ) extended Kalman filter to track angular head velocity and angular head acceleration. This method is independent of the device used for orientation measurement, relying on quaternion orientation as the only measurement data. A new orientation prediction algorithm is proposed that estimates future head orientation as a function of the current orientation measurement and a predicted change in orientation, using the velocity and acceleration estimates. Extensive experimentation shows that the new method improves head orientation prediction when compared to single filter DQ prediction. PMID:22692926

    Full Text Available Consistent with the global demand for palm oil, the intensified upstream harvesting activities of oil palms’ fresh fruit bunches, despite the harvesters evidences of various ergonomics risk factors leading to musculoskeletal disorders should be a cause for concern. Thus, this study describes the effectiveness of a modified and locally adapted Participatory Action-Oriented Training intervention program in improving the working environment of the harvesters. A training program modified and customized to the harvesters’ working in oil palm plantation consist of 3 primary instrument (awareness video, interactive lecture and action checklist with 3 reinforcing activities (to increase knowledge, enhance understanding and practical application. Based on the result of post-intervention assessment, the self-reported prevalence of MSD and KAP score among Intervention Group (IG did not significantly differ from Control Group (CG. Instead of decreasing, the prevalence of MSD in the past 12 months and 7 days increased within IG. Qualitative findings in this research show that the negative psychosocial and organizational climate has severely affected the implementation of PAOT rendering the effect of the intervention approach. The interventions were ineffective on the IG as this study suffers from various situational barriers as obstacles to benefit the full extent of PAOT advantages.

    2009-11-01

    Full Text Available Power management systems for embedded devices can be developed in real-time operating system (RTOS or in applications. If power management policies are applied in operating system (OS, then designers and developers will not have to worry about complex power management algorithms and techniques. They can rather concentrate on application development. The OS contains specific and accurate information about the various tasks being executed. An RTOS further has a comprehensive set of power management application programming interfaces (APIs for both device drivers and applications within a power management component. Therefore, it is logical to place policies and algorithms in the OS that can place components not being used into lower power states. This can significantly reduce the system energy consumption. We present here an abstract model of a system power manager (PM, device power managers, and application power managers. We present relationship and interactions of these managers with each other using Unified Modeling Language (UML class diagrams, sequence diagrams and state charts. We recommend that the PM must be implemented at the OS level in any embedded device. We also recommend the interfaces for interactions between PM and the devices power manager, as well as PM and application power manager. Device driver and application developers can easily use this object oriented approach to make the embedded system more power efficient, easy to maintain, and faster to develop.

    Martínez, R.; de Ipiña, K. López; Irigoyen, E.; Asla, N.

    People with intellectual disabilities and elderly need physical and intellectual support to ensuring independent living. This is one of the main issues in applying Information and Communication Technology (ICT) into Assistive Technology field. In this sense the development of appropriated Intelligent Systems (ISs) offers new perspectives to this community. In our project a new IS system (LAGUNTXO) which adds user affective information oriented to people with intellectual disabilities has been developed. The system integrates a Human Emotion Analysis System (HEAS) which attempts to solve critical situations for this community as block stages. In the development of the HEAS one of the critical issues was to create appropriated databases to train the system due to the difficulty to simulate pre-block stages in laboratory. Finally a films and real sequences based emotion elicitation database was created. The elicitation material was categorized with more actual features based on discrete emotions and dimensional terms (pleasant, unpleasant). Classically the evaluation is carried out by a specialist (psychologist). In this work we present a hybrid approach for Automatic Evaluation of Emotion Elicitation databases based on Machine Learning classifiers and K-means clustering. The new categorization and the automatic evaluation show a high level of accuracy with respect to others methodologies presented in the literature.

    2012-06-01

    Full Text Available Conventionally, user authentication and access control mechanisms would be almost enough, to handle security for stand-alone computers and small networks. Ad hoc networks are illustrated by multi-hop wireless connectivity and recurrently changing network topology which have made them infrastructure less. Adding trust to the existing security infrastructures would improvise the security of these environments. Describing trust relations and their sub-components using ontologies, creates a methodology and mechanism in order to efficiently design and engineer trust networks. This is going tobe used as a service for providing trust for ad hoc network at any level i.e. routing, authentication or access control. A trust oriented security framework for adhoc network using ontological engineering approach is proposed by modeling ad hoc network, the OLSR (Optimized Link State Routing protocol and trust model as OWL (Ontology Web language ontologies, which are integrated using Jena. In this model, a trustor can calculate its trust about trustee and use the calculated trust values to make decisions depending on the context of the application or interaction about granting or rejecting it. A number ofexperiments with a possible implementation of suggested framework are performed to make out the characteristics of the trust model and its effect on the ad hoc network operations.

    Claudia T. Pereira

    2012-07-01

    Full Text Available Modernization of legacy systems requires the existence of technical frameworks for information integration and tool interoperability that allow managing new platform technologies, design techniques and processes. MDA (Model Driven Architecture, adopted by the OMG (Object Management Group, is aligned with this requirement. Reverse engineering techniques play a crucial role in system modernization. In light of these issues, this article describes a framework to reverse engineering MDA models from object oriented code. This framework distinguishes three different abstraction levels linked to models, metamodels and formal specifications. At model level, transformations are based on static and dynamic analysis. At metamodel level, transformations are specified as OCL (Object Constraint Language contracts between MOF (Meta Object Facility metamodels which control the consistency of these transformations. The level of formal specification includes algebraic specifications of MOF metamodels and metamodel-based transformations. This article shows how to reverse engineering use case diagrams from Java code in the MDA context focusing on transformations at model and metamodel levels. We validate our approach by using Eclipse Modeling Framework, Ecore metamodels and ATL (Atlas Transformation Language.

  16. An object-oriented software approach for a distributed human tracking motion system

    Micucci, Daniela L.

    2003-06-01

    Tracking is a composite job involving the co-operation of autonomous activities which exploit a complex information model and rely on a distributed architecture. Both information and activities must be classified and related in several dimensions: abstraction levels (what is modelled and how information is processed); topology (where the modelled entities are); time (when entities exist); strategy (why something happens); responsibilities (who is in charge of processing the information). A proper Object-Oriented analysis and design approach leads to a modular architecture where information about conceptual entities is modelled at each abstraction level via classes and intra-level associations, whereas inter-level associations between classes model the abstraction process. Both information and computation are partitioned according to level-specific topological models. They are also placed in a temporal framework modelled by suitable abstractions. Domain-specific strategies control the execution of the computations. Computational components perform both intra-level processing and intra-level information conversion. The paper overviews the phases of the analysis and design process, presents major concepts at each abstraction level, and shows how the resulting design turns into a modular, flexible and adaptive architecture. Finally, the paper sketches how the conceptual architecture can be deployed into a concrete distribute architecture by relying on an experimental framework.

    2010-06-01

    Satellite sensor technology endorsed better discrimination of various landscape objects. Image segmentation approaches to extracting conceptual objects and patterns hence have been explored and a wide variety of such algorithms abound. To this end, in order to effectively utilize edge and topological information in high resolution remote sensing imagery, an object-oriented algorithm combining edge detection and region merging is proposed. Susan edge filter is firstly applied to the panchromatic band of Quickbird imagery with spatial resolution of 0.61 m to obtain the edge map. Thanks to the resulting edge map, a two-phrase region-based segmentation method operates on the fusion image from panchromatic and multispectral Quickbird images to get the final partition result. In the first phase, a quad tree grid consisting of squares with sides parallel to the image left and top borders agglomerates the square subsets recursively where the uniform measure is satisfied to derive image object primitives. Before the merger of the second phrase, the contextual and spatial information, (e. g., neighbor relationship, boundary coding) of the resulting squares are retrieved efficiently by means of the quad tree structure. Then a region merging operation is performed with those primitives, during which the criterion for region merging integrates edge map and region-based features. This approach has been tested on the QuickBird images of some site in Sanxia area and the result is compared with those of ENVI Zoom Definiens. In addition, quantitative evaluation of the quality of segmentation results is also presented. Experiment results demonstrate stable convergence and efficiency. PMID:20707163

    This paper deals with the development of a model for the nuclear research reactor TRIGA Mark II operating at University of Pavia. The purpose of the modeling is to reproduce the dynamic behavior of the reactor on the entire operative power range, i.e. 0-250 kW, using the object oriented approach, implemented by the Modelica language. The main advantage is the a-causal formulation of the model, based on equations instead of statement assignment. Equations do not specify which variables are inputs and which are outputs, thus the causality in the model is unspecified and is fixed only when the corresponding equation system is solved. In this way, equations can be solved according to the data flow context in which the solution is computed. The model describes the entire plant, including the heat removal system. The component representing the reactor core contains a series of sub-components linked together through rigorously defined interfaces: in this way, it is possible to consider the interactions between the different physical aspects of the system. Equations governing natural circulation have been implemented in a component which defines the mass flow rate through the core, according to the temperature difference at the ends of the channels. Secondary and tertiary cooling loops are modeled using a simplified heat exchangers configuration: concentric tube version is adopted, which allows recreating the heat exchange dynamics without a great modeling effort. The developed a-causal model has been validated through the comparison with experimental data collected on the site, concerning three different power transients at 100 kW, 50 kW and 1 kW. A corresponding causal model has been referenced as concerns fuel and coolant temperatures evolution during the transients. The predictions of the two main approaches to dynamic modeling have been compared. A very satisfying accordance is found as discrepancies observed on the coolant temperature are comprised between 0.5% and 1% for the three transients. (author)

The main advantage is the a-causal formulation of the model, based on equations instead of statement assignment. Equations do not specify which variables are inputs and which are outputs, thus the causality in the model is unspecified and is fixed only when the corresponding equation system is solved. In this way, equations can be solved according to the data flow context in which the solution is computed. The model describes the entire plant, including the heat removal system. The component representing the reactor core contains a series of sub-components linked together through rigorously defined interfaces: in this way, it is possible to consider the interactions between the different physical aspects of the system. Equations governing natural circulation have been implemented in a component which defines the mass flow rate through the core, according to the temperature difference at the ends of the channels. Secondary and tertiary cooling loops are modeled using a simplified heat exchangers configuration: concentric tube version is adopted, which allows recreating the heat exchange dynamics without a great modeling effort. The developed a-causal model has been validated through the comparison with experimental data collected on the site, concerning three different power transients at 100 kW, 50 kW and 1 kW. A corresponding causal model has been referenced as concerns fuel and coolant temperatures evolution during the transients. The predictions of the two main approaches to dynamic modeling have been compared. A very satisfying accordance is found as discrepancies observed on the coolant temperature are comprised between 0.5% and 1% for the three transients. (author)

    Landslides are considered one of the most important natural hazards. Mapping landslides and producing landslide inventory maps have received special attention from a wide range of specialists. The main objective of this study was to produce landslide inventory maps using advanced pixel-based (ANN and SVM) and object-oriented approaches. The most important challenge in this case is to determine the optimum structure of classification methods. The Taguchi method was to perform optimization of the structure of ANN and SVM and segmentation process in the object-oriented classification method. Results showed that the Taguchi method can be effectively used to cope with this problem. It significantly reduces the number of classification tests. We also showed that there were no significant differences existed between ANN and SVM approaches (χ2 value of 3.33). However, we demonstrated that object-oriented approaches significantly outperformed the pixel-based classification methods (Z value of 5.70) in producing a landslide inventory map. The accurate map produced using an object-oriented approach (overall accuracy of 0.90) effectively determines the shape of landslides and also efficiently shows the intensifying effects of land use changes in the occurrence of landslides.

  4. Aspect-Oriented Development Method for Non-Functional Characteristics of Cyber Physical Systems Based on MDA Approach

    2012-03-01

    Full Text Available Cyber physical systems have many non-functional requirements, which always crosscut the whole system modules. That may cause the code tangle and scatter, make the systems hard to design, reuse and maintain, and affect performance of systems badly. AOP is a new software development paradigm, which could attain a higher level of separation of concerns in both functional and non-functional matters by introducing aspect, for the implementation of crosscutting concerns. Different aspects can be designed separately, and woven into systems. In this paper, we propose an aspect-oriented MDA approach for non-functional properties to develop cyber physical systems. An aspect-oriented UML profile is built to develop cyber physical systems. Aspect-oriented UML models are designed as Platform Independent Models (PIM for target-platform implementation, which deal with non-functional properties. OCL formal language is used to restrict the model in every stages of MDA, and the real-time extension of OCL formal language is made to describe the timing constraints of cyber physical systems. Finally, the model- based development and aspect-oriented approach, the formal methods and the cyber physical system are integrated effectively. A case study illustrates the aspect oriented MDA development of cyber physical systems.

    The federation of databases is not a new endeavor. Great strides have been made e.g. in the health and astrophysics communities. Reviews of those successes indicate that they have been able to leverage off key cross-community core concepts. In its simplest implementation, a federation of databases with identical base schemas that can be extended to address individual efforts, is relatively easy to accomplish. Efforts of groups like the Open Geospatial Consortium have shown methods to geospatially relate data between different sources. We present here a summary of CHRONOS's (http://www.chronos.org) experience with highly heterogeneous data. Our experience with the federation of very diverse databases shows that the wide variety of encoding options for items like locality, time scale, taxon ID, and other key parameters makes it difficult to effectively join data across them. However, the response to this is not to develop one large, monolithic database, which will suffer growth pains due to social, national, and operational issues, but rather to systematically develop the architecture that will enable cross-resource (database, repository, tool, interface) interaction. CHRONOS has accomplished the major hurdle of federating small IT database efforts with service-oriented and XML-based approaches. The application of easy-to-use procedures that allow groups of all sizes to implement and experiment with searches across various databases and to use externally created tools is vital. We are sharing with the geoinformatics community the difficulties with application frameworks, user authentication, standards compliance, and data storage encountered in setting up web sites and portals for various science initiatives (e.g., ANDRILL, EARTHTIME). The ability to incorporate CHRONOS data, services, and tools into the existing framework of a group is crucial to the development of a model that supports and extends the vitality of the small- to medium-sized research effort that is essential for a vibrant scientific community. This presentation will directly address issues of portal development related to JSR-168 and other portal API's as well as issues related to both federated and local directory-based authentication. The application of service-oriented architecture in connection with ReST-based approaches is vital to facilitate service use by experienced and less experienced information technology groups. Application of these services with XML- based schemas allows for the connection to third party tools such a GIS-based tools and software designed to perform a specific scientific analysis. The connection of all these capabilities into a combined framework based on the standard XHTML Document object model and CSS 2.0 standards used in traditional web development will be demonstrated. CHRONOS also utilizes newer client techniques such as AJAX and cross- domain scripting along with traditional server-side database, application, and web servers. The combination of the various components of this architecture creates an environment based on open and free standards that allows for the discovery, retrieval, and integration of tools and data.

    Without intervention, classic galactosemia is a potentially fatal disorder in infancy. With the benefit of early diagnosis and dietary restriction of galactose, the acute sequelae of classic galactosemia can be prevented or reversed. However, despite early and lifelong dietary treatment, many galactosemic patients go on to experience serious long-term complications including cognitive disability, speech problems, neurological and/or movement disorders and, in girls and women, ovarian dysfunction. Further, there remains uncertainty surrounding what constitutes a 'best practice' for treating this disorder. To explore the extent and implications of this uncertainty, we conducted a small but global survey of healthcare providers who follow patients with classic galactosemia, seeking to compare established protocols for diagnosis, intervention, and follow-up, as well as the outcomes and outcome frequencies seen in the patient populations cared for by these providers. We received 13 survey responses representing five continents and 11 countries. Respondents underscored disparities in approaches to diagnosis, management and follow-up care. Notably, we saw no clear relationship between differing approaches to care and long-term outcomes in the populations studied. Negative outcomes occurred in the majority of cases regardless of when treatment was initiated, how tightly galactose intake was restricted, or how closely patients were monitored. We document here what is, to our knowledge, the first global comparison of healthcare approaches to classic galactosemia. These data reinforce the idea that there is currently no one best practice for treating patients with classic galactosemia, and underscore the need for more extensive and statistically powerful comparative studies to reveal potential positive or negative impacts of differing approaches.

    Full Text Available The International Atomic Energy Agency (IAEA launched a Coordinated Research Program in 10 developing countries including Pakistan involving small scale market oriented dairy farmers to identify and prioritize the constraints and opportunities in the selected dairy farms, develop intervention strategies and assess the economic impact of the intervention. The interventions in animal health (control of mastitis at sub-clinical stage and reduction in calf mortality, nutrition (balanced feed reproduction (mineral supplementation, and general management (training of farmers were identified and implemented in a participatory approach at the selected dairy farms. The calf mortality was reduced from 35 to 13 percent up to the age of 3 months. Use of Alfa Deval post milking teat dips reduced the incidence of sub-clinical mastitis from 34 to 5% showing economical benefits of the interventions. Partial budget technique was used to analyze its impact in the registered herds. The farmers recorded monthly quantities of different feed ingredients and seasonal green fodder offered to the animals. From this data set total metabolizeable energy requirements and availability from feed were computed which revealed that animals were deficient in metabolizeable energy in all locations. This was also confirmed by seasonal variation in body condition scoring. At some selected farms the mineral mixture supplement was introduced which exhibited increased milk yield by 5 % in addition to shorten service period by 30 days. Three sessions of training were arranged to train the farmers to care new born calves, daily farm management and detect the animals in heat efficiently to enhance the over all income of the farmers. The overall income of the farm was increased by 40%.

    Full Text Available Several studies have attempted to characterize morphological brain changes due to chronic pain. Although it has repeatedly been suggested that longstanding pain induces gray matter modifications, there is still some controversy surrounding the direction of the change (increase or decrease in gray matter and the role of psychological and psychiatric comorbidities. In this study, we propose a novel, network-oriented, meta-analytic approach to characterize morphological changes in chronic pain. We used network decomposition to investigate whether different kinds of chronic pain are associated with a common or specific set of altered networks. Representational similarity techniques, network decomposition and model-based clustering were employed: i to verify the presence of a core set of brain areas commonly modified by chronic pain; ii to investigate the involvement of these areas in a large-scale network perspective; iii to study the relationship between altered networks and; iv to find out whether chronic pain targets clusters of areas. Our results showed that chronic pain causes both core and pathology-specific gray matter alterations in large-scale networks. Common alterations were observed in the prefrontal regions, in the anterior insula, cingulate cortex, basal ganglia, thalamus, periaqueductal gray, post- and pre-central gyri and inferior parietal lobule. We observed that the salience and attentional networks were targeted in a very similar way by different chronic pain pathologies. Conversely, alterations in the sensorimotor and attention circuits were differentially targeted by chronic pain pathologies. Moreover, model-based clustering revealed that chronic pain, in line with some neurodegenerative diseases, selectively targets some large-scale brain networks. Altogether these findings indicate that chronic pain can be better conceived and studied in a network perspective.

    Full Text Available According to application a database is designed to be object-oriented model or relational model but the important point is distribution and heterogeneity. So a model should be provided which work with different types of database and also be able to work disruption, and heterogeneity So one of the great challenges in the use of distributed database technologies is integrating object-oriented databases with relational databases because the platform-independent technologies have an object-oriented approach But today databases are usualy designed and implemented base on relational model. Hence this paper tries to offer a model that could bring further coordination and integration between these two exsisting database models

    2015-10-01

    Full Text Available Evidence points to the fact that frequent resignation of project engineers from construction companies is primarily the result of dissatisfaction with the factors that shape the salary scale. This research aims to identify the major influencing factors in merit based salary calculation systems for knowledge-oriented engineers so as to more accurately reflect their contribution to construction projects. Results from a questionnaire sent to managers, engineers and HR professionals throughout the Iranian construction industry revealed that while there was overall agreement on principles to a merit-based approach, engineers in particular identified ‘professional skills’, ‘experience’ and ‘creativity’. Management-oriented parties should take into account engineer perspectives in order to more accurately value the knowledge-oriented contribution of these workers to construction projects. This research provides a basis for understanding the key factors in the merit based salary scale formulation through the construction industry.

    Full Text Available The study aims to investigate the effects of entrepreneurial orientation on firm performance. Entrepreneurial orientation has emerged as an important construct within the strategic management and entrepreneurship literatures over the past two decades. In recent times, especially with the growth of globalization and other such factors, the performance measurement standards and parameters have changed. This has also led to a significant change in the factors that are now used within the operational sphere of an organization in order to affect the firm performance. Empirical studies on the determinants of firm performance have identified that the entrepreneurial orientation of the firms senior management has a significant positive influence. However, the study suggests that the performance implications of entrepreneurial orientation might vary depending on the firms circumstances.

    2014-10-01

    An analysis and some generalizations of approaches to risk assessments are presented. Interconnection between different interpretations of the "risk" notion is shown, and the possibility of applying the fuzzy set theory to risk assessments is demonstrated. A generalized formulation of the risk assessment notion is proposed in applying risk-oriented approaches to the problem of enhancing reliability and safety in nuclear power engineering. The solution of problems using the developed risk-oriented approaches aimed at achieving more reliable and safe operation of NPPs is described. The results of studies aimed at determining the need (advisability) to modernize/replace NPP elements and systems are presented together with the results obtained from elaborating the methodical principles of introducing the repair concept based on the equipment technical state. The possibility of reducing the scope of tests and altering the NPP systems maintenance strategy is substantiated using the risk-oriented approach. A probabilistic model for estimating the validity of boric acid concentration measurements is developed.

  5. Magnetic orientation of the Common Toad: establishing an arena approach for adult anurans

    Gollmann Günter

    2011-03-01

    Full Text Available Abstract Background Magnetic orientation is a taxonomically widespread phenomenon in the animal kingdom, but has been little studied in anuran amphibians. We collected Common Toads (Bufo bufo during their migration towards their spawning pond and tested them shortly after displacement for possible magnetic orientation in arena experiments. Animals were tested in two different set-ups, in the geomagnetic field and in a reversed magnetic field. To the best of our knowledge, this is the first study testing orientation of adult anurans with a controlled magnetic field of a known strength and alignment. Results After displacement, toads oriented themselves unimodally under the geomagnetic field, following their former migration direction (d-axis. When the magnetic field was reversed, the distribution of bearings changed from a unimodal to a bimodal pattern, but still along the d-axis. The clustering of bearings was only significant after the toads reached the outer circle, 60.5 cm from their starting point. At a virtual inner circle (diameter 39 cm and at the start of the experiment, orientation of toads did not show any significant pattern. Conclusions The experimental set-up used in our study is suitable to test orientation behaviour of the Common Toad. We speculate that toads had not enough time to relocate their position on an internal map. Hence, they followed their former migration direction. Bimodality in orientation when exposed to the reversed magnetic field could be the result of a cue conflict, between magnetic and possibly celestial cues. For maintaining their migration direction toads use, at least partly, the geomagnetic field as a reference system.

  7. Impact of Different Treatment Approaches on Pregnancy Outcomes in 99 Women Treated for Hodgkin Lymphoma

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to evaluate the pregnancy outcomes in women with Hodgkin lymphoma (HL) diagnosis, treated between 1972 and 1999 at Department of Radiotherapy and Hematology of University “Sapienza” of Roma. Methods and Materials: We retrospectively studied 99 female patients that conceived after treatment for HL. Fifty-nine (59%) were treated with chemotherapy and radiotherapy, 32 (32%) with radiotherapy alone as supradiaphragmatic or as infradiaphragmatic and 8 (8%) patients with chemotherapy alone. Results: Ninety-nine patients reported 145 pregnancies. We observed 132 deliveries (2 of them twin births) after a median of 55 months (range, 14–278 months) from the end of therapy. Twelve women (12%) experienced 13 miscarriages after a median of 50 months (range, 13–120) from the end of therapy. We recorded 9/132 (7%) premature births and 3/134 babies (2%) were underweight at the time of birth. We recorded 2 cases of congenital malformations. No statistical differences were recorded when adverse pregnancy outcomes were analyzed with respect to chemotherapy alone, radiotherapy alone, or combined therapy. Conclusions: No significant associations between pregnancy outcomes and therapeutic approaches were found. In particular, the infradiaphragmatic radiotherapy showed no statistical association with miscarriages, premature birth, and low birth weight at term when compared with other therapeutic approaches.

    Public transportation has declined because policymakers and outdated regulations have restricted the evolution of transportation systems which more closely reflect the mobility and lifestyles of today. Public policy needs to take a consumer-oriented approach to public transportation by recognizing that all consumers do not have the same transportation needs and that one or two modes of transportation cannot satisfy these needs. This report argues that if public transportation is to become an efficient method of satisfying the transportation needs of a community, a brokerage or consumer-oriented approach should be adopted. The transportation broker will match specific individual needs with a broad array of transportation services, and overcome institutional, legal, and operational barriers to the development of new forms of transportation service. 51 references or footnotes.

    Full Text Available It is commonly held that pseudo-oriental letters used anOriental mask to comment on contemporary European society andmanners; Eastern contexts, proverbs, customs and culture were thoughtto be supplementary to the central theme. Therefore, the representationof the Ottoman Orient in the letters was taken as of mostly illustrative(Conant, 157-61. However, it is not illuminating to argue that pseudoorientalletters were mainly concerned with the discussion ofcontemporary social and political issues. We can find more thanillusion in the letters in terms of the representation of the OttomanOrient. We will survey the historical process can disclose theinteraction between Europe and the Orient and unravel the consistentspirit which reinforced the negotiation between East and West. Thecritical perspectives in the Turkish Spy and Persian Letters blended thepositive and negative aspects of the two worlds; the pseudo-orientalletters amalgamated the familiar and unfamiliar, ridiculous and seriousfacets of the Eastern and Western cultures. The use of Orientalnarrators worked as a metaphor for the intellectual and culturaltransformation of Eastern and Western perceptions of each other. Thistransformation created a critical narrative tradition where Eastern andWestern values had contact, clashed, and found a way to get rid ofreligious prejudice. Using Bakhtin’s concept of dialogy, the presentpaper aims to discuss how the two continents interanimated each otherby disclosing the serious and absurd aspects of the two cultures.

    Structural geologists typically invoke the Mohr-Coulomb failure criterion to explain the orientations of shear fractures. Nevertheless, there have been recent attempts to explain shear fracture orientation in terms of finite strain or strain increment. In these models, spatial variations in shear fracture orientation are explained by spatial variations in the orientations of lines of no finite elongation (LNFE), and/or zero extension directions. We test these models by analysing the orientations of conjugate cataclastic deformation bands that cut unconsolidated sand and gravel at McKinleyville, California, and dip shallowly towards the north-northeast and south-southwest. The acute dihedral angle between the two sets of deformation bands is 47° and is bisected by the sub-horizontal, north-northeast directed incremental and finite shortening directions. Trishear models of fault propagation folding above the McKinleyville fault predict two sets of LNFE that plunge steeply and shallowly to the south and north. These predictions are inconsistent with deformation band orientations and suggest that deformation bands did not form parallel to these LNFE. During plane strain, zero extension directions with acute dihedral angles of 47° develop when the dilatancy rate is 4.3. Experimental dilatancy rates for Vosges sandstone (cohesion > 0) and unconsolidated Hostun sand suggest the deformation bands either developed parallel to zero extension directions or in accordance with the Mohr-Coulomb criterion, assuming initial porosities of 22% and 39%, respectively. However, an empirical relationship between dilatancy rate, relative density and mean stress suggests that dilatancy rates for Vosges sandstone overestimate the dilatancy rate at McKinleyville. Deformation bands at McKinleyville likely developed either in a Mohr-Coulomb orientation, or an intermediate orientation bounded by the Mohr-Coulomb and Roscoe angles. These results suggest that approaches based on strain or strain increment (i.e. kinematic models) should be used with caution when predicting shear fracture orientations, and should not be used to populate discrete fracture network (DFN) models without careful consideration of their validity.

    Miao, Yongwu; Hermans, Henry

    This chapter presents a process-oriented approach to support assessment in learning networks. Assessment in its broadest sense can be conceived as the ‘systematic gathering of information and evidence about a person’s properties (qualifications), based on a process, a product or the progress of a person, for the purposes of certification, placement or diagnoses in formative and summative contexts’ (Joosten-ten Brinke et al. 2007). This definition includes classical assessment and complex assessment.

    Full Text Available The main potential benefit of Service-oriented architecture (SOA is applying across multiple solution environments based on the request and reply paradigm. Service-oriented architecture integrates both enterprise and application architectures. When the services and size of the workflow increases, the SOA orchestration reaches the scalability limits and same effected on the data transmission between services, a standard orchestration desires to transport all the data through a workflow engine when communicate on the web service without any third party data transfer, which results redundant data transfer and engine to become a bottleneck to execution of a workflow. As a solution, we present Promulgate, an alternative service-oriented architecture. Promulgate proposed an orchestration model as central control in grouping with a choreography model of optimized distributed data transport. We are using Data caching techniques by using dynamic proxy deployment and SOAP compression techniques by using zipped SOAP for this hybrid architecture to optimize the data transfer in SOA.

  14. A bootstrap approach for assessing the uncertainty of outcome probabilities when using a scoring system

    Full Text Available Abstract Background Scoring systems are a very attractive family of clinical predictive models, because the patient score can be calculated without using any data processing system. Their weakness lies in the difficulty of associating a reliable prognostic probability with each score. In this study a bootstrap approach for estimating confidence intervals of outcome probabilities is described and applied to design and optimize the performance of a scoring system for morbidity in intensive care units after heart surgery. Methods The bias-corrected and accelerated bootstrap method was used to estimate the 95% confidence intervals of outcome probabilities associated with a scoring system. These confidence intervals were calculated for each score and each step of the scoring-system design by means of one thousand bootstrapped samples. 1090 consecutive adult patients who underwent coronary artery bypass graft were assigned at random to two groups of equal size, so as to define random training and testing sets with equal percentage morbidities. A collection of 78 preoperative, intraoperative and postoperative variables were considered as likely morbidity predictors. Results Several competing scoring systems were compared on the basis of discrimination, generalization and uncertainty associated with the prognostic probabilities. The results showed that confidence intervals corresponding to different scores often overlapped, making it convenient to unite and thus reduce the score classes. After uniting two adjacent classes, a model with six score groups not only gave a satisfactory trade-off between discrimination and generalization, but also enabled patients to be allocated to classes, most of which were characterized by well separated confidence intervals of prognostic probabilities. Conclusions Scoring systems are often designed solely on the basis of discrimination and generalization characteristics, to the detriment of prediction of a trustworthy outcome probability. The present example demonstrates that using a bootstrap method for the estimation of outcome-probability confidence intervals provides useful additional information about score-class statistics, guiding physicians towards the most convenient model for predicting morbidity outcomes in their clinical context.

    Full Text Available Introduction. Risk stratification is nowadays crucial when estimating the patient’s prognosis in terms of treatment outcome and it also helps in clinical decision making. Several risk assessment models have been developed to predict short-term outcomes in patients with acute coronary syndrome. This study was aimed at developing an outcome prediction model for patients with acute coronary syndrome submitted to percutaneus coronary intervention using data mining approach. Material and Methods. A total of 2030 patients hospitalized for acute coronary syndrome and treated with percutaneous coronary intervention from December 2008 to December 2011 were assigned to a derivation cohort. Demographic and anamnestic data, clinical characteristics on admission, biochemical analysis of blood parameters on admission, and left ventricular ejection fraction formed the basis of the study. A number of machine learning algorithms available within Waikato Environment for Knowledge Discovery had been evaluated and the most successful was chosen. The predictive model was subsequently validated in a different population of 931 patients (validation cohort, hospitalized during 2012. Results. The best prediction results were achieved using Alternating Decision Tree classifier, which was able to predict in-hospital mortality with 89% accuracy, and preserved good performance on validation cohort with 87% accuracy. Alternating Decision Tree classifier identified a subset of 6 attributes most relevant to mortality prediction: systolic and diastolic blood pressure, heart rate, left ventricular ejection fraction, age, and troponin value. Conclusion. Data mining approach enabled the authors to develop a model capable of predicting the in-hospital outcome following percutaneous coronary intervention. The model showed excellent sensitivity and specificity during internal validation.

  18. Consolation as a unique outcome within a pastoral-narrative approach to grief

    2009-09-01

    Full Text Available Abstract Consolation as a unique outcome within a pastoral-narrative approach to grief The pastoral counselling of those who grieve, poses new challenges to pastoral care. Because of the shift away from a modernist paradigm, the grief process is now seen as an open-ended process rather than a closed process which focuses on the mastering of the so-called tasks of mourning and the avoidance of grief pathology. Recent grief theory suggests that the grief process cannot reach a point of closure. Grief counselling should therefore rather embark on a process of generating new meaning to the problem-saturated discourses surrounding death and loss. Narrative therapy is suggested as a means of grief counselling as it makes use of the story analogy which supports the notion of an open end to the grief process. In this study the narrative is explored within the framework of practical theology. Both the master Story of God and the grief-saturated stories of people are combined in a pastoral approach which envisages consolation as the unique outcome of the therapeutic process. Consolation is regarded as one of the secondary narratives in the greater narrative of God as well as the reformed theological vocabulary. It is suggested that a pastoral-narrative approach to grief will generate the consolation needed by the grief-stricken on their life-long journey of coming to terms with their loss.

    Aim: A retroperitoneal approach for abdominal aortic aneurysm repair has demonstrated similar short-term postoperative outcomes compared with the transperitoneal approach. However, there is no long-term survival data utilizing exclusively open repair via retroperitoneal approach. Methods: We have conducted a retrospective analysis to evaluate the long-term survival of 142 patients with infrarenal aortic aneurysm undergoing elective open surgical repair via a retroperitoneal approach. Results: Our cohort of patients consisted of 82% males, 59% whites, and a mean age of 72.6±7.7 years. The 30-day mortality rate was 3.5% for open repair via retroperitoneal approach. Post-operative complications were low, with renal failure (9.9%), pulmonary complication (9.9%), and limb ischemia (6.3%) being the most prevalent. Five years after surgery, the cumulative survival rate was 70.1%. Conclusion: The elective management of infrarenal aortic aneurysms with open repair via a retroperitoneal approach offers a good prognosis demonstrated with up to 5 year follow up. PMID:24104586

    One of the most important challenges in the injection molding process of the short-glass fiber/thermoplastic composite parts is being able to predict the fiber orientation, since it controls the mechanical and the physical properties of the final parts. Folgar and Tucker included into the Jeffery equation a diffusive type of term, which introduces a phenomenological coefficient for modeling the randomizing effect of the mechanical interactions between the fibers, to predict the fiber orientation in concentrated suspensions. Their experiments indicated that this coefficient depends on the fiber volume fraction and aspect ratio. However, a definition of the fiber interaction coefficient, which is very necessary in the fiber orientation simulations, hasn't still been proven yet. Consequently, this study proposed a developed fiber interaction model that has been introduced a fiber dynamics simulation in order to obtain a global fiber interaction coefficient. This supposed that the coefficient is a sum function of the fiber concentration, aspect ratio, and angular velocity. The proposed model was incorporated into a computer aided engineering simulation package C-Mold. Short-glass fiber/polyamide-6 composites were produced in the injection molding with the fiber weight concentration of 30 wt.%, 50 wt.%, and 70 wt.%. The physical properties of these composites were examined, and their fiber orientation distributions were measured by micro-computed-tomography equipment ?-CT. The simulation results showed a good agreement with experiment results.

    Full Text Available An optimal logical topology of a wireless sensor ne twork (WSN facilitates the deployed sensor nodes t o communicate with each other with little overheads, lowers energy consumption, lengthens lifetime of th e network, provides scalability, increases reliabilit y, and reduces latency. Designing an optimal logica l topology for a WSN thus needs to consider numerous factors. Chain oriented topologies have been found to offer a number of improvements in energy consump tions, lifetime, and load balancing than other topologies of WSNs. However, they usually suffer fr om latency, scalability, reliability and interferen ce problems. In this paper, we present a chain oriente d logical topology, which offers solutions to those problems. The proposed topology is designed such th at it retains the advantages of the chain oriented topologies, and at the same time, overcomes the pro blems of the chain oriented topology such as latenc y, scalability, and data reliability. The proposed top ology provides a communication abstraction, which c an be easily used to devise a range of application pro tocols. Moreover, the logical topology offers node management, resource management, and other services . The performance of the proposed topology is compared with other topologies in respect to total energy consumption and lifetime of the network

  11. Structuring requirements as necessary premise for customer-oriented development of complex products: A generic approach

    Directory of Open Access Journals (Sweden)

    Sandra Klute

    2011-10-01

    Full Text Available Purpose: Complex products like for example intra-logistical facilities make high demands on developers and producers and involve high investment and operating costs. When planning and developing and also making buying decisions the facility utilization and the thus ensuing requirements on the facility and its components are inadequately considered to date. Nevertheless, with regard to customer-directed product design, these requirements must all be taken into account – especially as they can contribute to possible savings. In this context, it is necessary to survey and systematically regard requirements from a large number of areas like for example the operator, the facility producer and also requirements of external parties such as the law and to implement into adequate product characteristics to produce customer-oriented products. This is, however, a difficult task because of the diversity of stakeholders involved and their numerous and often divergent requirements. Therefore, it is essential to structure the requirements, so that planners and developers are able to manage the large amount of information. Structure models can be used in this context to cluster requirements. Within the German Collaborative Research Centre 696 a 10-dimensional model has been developed. This model allows structuring of all requirements on intra-logistical facilities or respectively complex products in general. In the context of dealing with hundreds of data records, structuring requirements is mandatory to achieve accuracy, clarity and consequently satisfactory results when transforming requirements into product characteristics which fit customer needs. In the paper an excerpt of this model is presented. Design/methodology/approach: In literature a multitude of methods which deal with the topic of structuring exist. The methods have been analysed regarding their purpose and their level of specification, i.e. the number of differentiated categories, to check if they could be applied in the regarded area of intra-logistics. Also potential stakeholders have been identified to ensure that the surveying of requirements is not incomplete. Based on these analyses an own model has been developed which combines, adepts and enlarges the existing methods. Findings: A 10-dimensional model has been developed for structuring requirements on intra-logistical facilities. This model is holistic, because additionally it allows capturing the stakeholders’ feedback to the requirements’ fulfilment. The dimensions of the model can be divided into four groups. The first one serves to structure the requirements regarding their content. These are the dimensions obligations, surroundings, information, qualification, technical-functional requirements and qualification. The second group serves to structure the reference object to which the requirements refer and includes the dimension product. Weighted level of performance and customer satisfaction are part of the third group, which encompasses the evaluation of the requirements’ fulfilment. The fourth group is for the temporal structuring of requirements and includes the dimension time. For applying the model it has been implemented for data processing as component of a large data processing system. The developed model is presented in this paper. Research limitations/implications: A 10-idimensional model for structuring requirements is presented in this paper. Thereby, a sub-division of the dimensions into categories and sub-categories has been made to ensure a topical classification of the requirements and additionally a structuring according to their level of specification. Considering individual dimensions and/or selected categories of dimensions allow a thematic focus to be placed on certain groups of requirements. This is particularly important, not only for the implementation of requirements into solutions but also for focusing on the needs of individual stakeholders, if e.g. requirements on maintenance have to be observed. Using the model, working with lots of requ

    Full Text Available Enzymes are powerful biocatalysts, however, so far there is still a large gap between the number of enzyme-based practical applications and that of naturally occurring enzymes. Multiple experimental approaches have been applied to generate nearly all possible mutations of target enzymes, allowing the identification of desirable variants with improved properties to meet the practical needs. Meanwhile, an increasing number of computational methods have been developed to assist in the modification of enzymes during the past few decades. With the development of bioinformatic algorithms, computational approaches are now able to provide more precise guidance for enzyme engineering and make it more efficient and less laborious. In this review, we summarize the recent advances of method development with significant biological outcomes to provide important insights into successful computational protein designs. We also discuss the limitations and challenges of existing methods and the future directions that should improve them.

    2009-10-01

    In this paper, we propose a novel scheme towards the recognition of multi-oriented and multi-sized isolated characters of printed script. For recognition, at first, distances of the outer contour points from the centroid of the individual characters are calculated and these contour distances are then arranged in a particular order to get size and rotation invariant feature. Next, based on the arranged contour distances, the features are derived from different class of characters. Finally, we use these derived features of the characters to statistically compare the features of the input character for recognition. We have tested our scheme on printed Bangla and Devnagari multi-oriented characters and we obtained encouraging results.

    2013-02-01

    Full Text Available Software developers develop their software with some standard specification, but important issue is how to measure the quality of software modularization. In this paper advanced set of metrics are proposed which measure quality of modularization of an Object-Oriented Software (OOS System. Metrics are designed with universal standard principles to measure the quality of Object-Oriented software which has been developed. Proposed metrics are coupling based structural metrics, these metrics measures the function-call traffic through the API’s of the modules in relation to the overall function-call traffic. It is universally accepted that quality of the software modularization is improved when interaction between modules of system is through published APIs only. The metrics can be validated from the results obtained on human-modularized versions of the software.

    2012-01-01

    Oriental ink painting, called Sumi-e, is one of the most appealing painting styles that has attracted artists around the world. Major challenges in computer-based Sumi-e simulation are to abstract complex scene information and draw smooth and natural brush strokes. To automatically find such strokes, we propose to model the brush as a reinforcement learning agent, and learn desired brush-trajectories by maximizing the sum of rewards in the policy search framework. We also provide elaborate de...

    Inference of model parameters is one step in an engineering process often ending in predictions that support decision in the form of design or control. Incorporation of end goals into the inference process leads to more efficient goal-oriented algorithms that automatically target the most relevant parameters for prediction. In the linear setting the control-theoretic concepts underlying balanced truncation model reduction can be exploited in inference through a dimensionally optimal subspace ...

    A new method using a double-sensor difference based algorithm for analyzing human segment rotational angles in two directions for segmental orientation analysis in the three-dimensional (3D) space was presented. A wearable sensor system based only on triaxial accelerometers was developed to obtain the pitch and yaw angles of thigh segment with an accelerometer approximating translational acceleration of the hip joint and two accelerometers measuring the actual accelerations on the thigh. To evaluate the method, the system was first tested on a 2 degrees of freedom mechanical arm assembled out of rigid segments and encoders. Then, to estimate the human segmental orientation, the wearable sensor system was tested on the thighs of eight volunteer subjects, who walked in a straight forward line in the work space of an optical motion analysis system at three self-selected speeds: slow, normal and fast. In the experiment, the subject was assumed to walk in a straight forward way with very little trunk sway, skin artifacts and no significant internal/external rotation of the leg. The root mean square (RMS) errors of the thigh segment orientation measurement were between 2.4 degrees and 4.9 degrees during normal gait that had a 45 degrees flexion/extension range of motion. Measurement error was observed to increase with increasing walking speed probably because of the result of increased trunk sway, axial rotation and skin artifacts. The results show that, without integration and switching between different sensors, using only one kind of sensor, the wearable sensor system is suitable for ambulatory analysis of normal gait orientation of thigh and shank in two directions of the segment-fixed local coordinate system in 3D space. It can then be applied to assess spatio-temporal gait parameters and monitoring the gait function of patients in clinical settings. PMID:19748624

    2015-11-01

    Today, industries ensure the quality of their manufactured products through computer vision techniques and nonconventional imaging. Three-dimensional (3-D) scanners and nondestructive testing (NDT) systems are commonly used independently for such applications. Furthermore, these approaches combined constitute hybrid systems, providing a 3-D reconstruction and NDT analysis. These systems, however, suffer from drawbacks such as errors during the data fusion and higher cost for manufacturers. In an attempt to solve these problems, a single active thermography system based on scanning-from-heating is proposed in this paper. In addition to 3-D digitization of the object, our contributions are twofold: (1) the nonthrough defect detection for a homogeneous metallic object and (2) fiber orientation assessment for a long fiber composite material. The experiments on steel and aluminum plates show that our method achieves the detection of nonthrough defects. Additionally, the estimation of the fiber orientation is evaluated on carbon-fiber composite material.

  9. [Process orientation as a tool of strategic approaches to corporate governance and integrated management systems].

    2010-01-01

    The concept of general process orientation as an instrument of organisation development is the core principle of quality management philosophy, i.e. the learning organisation. Accordingly, prestigious quality awards and certification systems focus on process configuration and continual improvement. In German health care organisations, particularly in hospitals, this general process orientation has not been widely implemented yet - despite enormous change dynamics and the requirements of both quality and economic efficiency of health care processes. But based on a consistent process architecture that considers key processes as well as management and support processes, the strategy of excellent health service provision including quality, safety and transparency can be realised in daily operative work. The core elements of quality (e.g., evidence-based medicine), patient safety and risk management, environmental management, health and safety at work can be embedded in daily health care processes as an integrated management system (the "all in one system" principle). Sustainable advantages and benefits for patients, staff, and the organisation will result: stable, high-quality, efficient, and indicator-based health care processes. Hospitals with their broad variety of complex health care procedures should now exploit the full potential of total process orientation. PMID:20951952

    Chemical regulation is challenged by the large number of chemicals requiring assessment for potential human health and environmental impacts. Current approaches are too resource intensive in terms of time, money and animal use to evaluate all chemicals under development or already on the market. The need for timely and robust decision making demands that regulatory toxicity testing becomes more cost-effective and efficient. One way to realize this goal is by being more strategic in directing testing resources; focusing on chemicals of highest concern, limiting testing to the most probable hazards, or targeting the most vulnerable species. Hypothesis driven Integrated Approaches to Testing and Assessment (IATA) have been proposed as practical solutions to such strategic testing. In parallel, the development of the Adverse Outcome Pathway (AOP) framework, which provides information on the causal links between a molecular initiating event (MIE), intermediate key events (KEs) and an adverse outcome (AO) of regulatory concern, offers the biological context to facilitate development of IATA for regulatory decision making. This manuscript summarizes discussions at the Workshop entitled "Advancing AOPs for Integrated Toxicology and Regulatory Applications" with particular focus on the role AOPs play in informing the development of IATA for different regulatory purposes.

    1997-01-01

    This paper presents a state-of-art review of empirical research on object-oriented (OO) design. Many claims about the cognitive benefits of the OO paradigm have been made by its advocates. These claims concern the ease of designing and reusing software at the individual level as well as the benefits of this paradigm at the team level. Since these claims are cognitive in nature, its seems important to assess them empirically. After a brief presentation of the main concepts of the OO paradigm, the claims about the superiority of OO design are outlined. The core of this paper consists of a review of empirical studies of OOD. We first discuss results concerning OOD by individuals. On the basis of empirical work, we (1) analyse the design activity of novice OO designers, (2) compare OO design with procedural design and, (3) discuss a typology of problems relevant for the OO approach. Then we assess the claims about naturalness and ease of OO design. The next part discusses results on OO software reuse. On the basi...

  13. Education Standards and Competence-oriented Curricula - The Austrian Technical Colleges Take a New Approach to Excellence

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available In Austria, Technical Colleges are those educational institutions that train and educate the skilled technical staff required by the Austrian labour market and the universities. These colleges have contributed a lot to Austria’s economic success and every year about 8,000 young engineers leave the technical schools to form a powerful work and study force. Therefore, it is particularly important that the education they receive meets the requirements of prospective employers and that innovative developments are anticipated. As a consequence, the Austrian Technical Colleges have developed curricula that rely on learning outcomes and competence-based results. This new orientation towards skills, knowledge and competences shall be achieved through learning objectives that precisely describe the education chosen. How these standards have been designed, matched with the curricula, and implemented at the Colleges will be described in this paper.

  14. Economic approaches to improving access to evidence-based and recovery-oriented services for people with severe mental illness.

    2011-09-01

    During the past 3 decades, research has identified several psychosocial evidence-based practices (EBPs) for people with severe mental illness (SMI). Starting from a different origin, the recovery movement has influenced perceptions of how EBPs and other services should be delivered, and also emphasized the value of peer supports. We now know much more than 30 years ago about the kinds of services that help people with SMI live satisfying lives in the community. Evidence-based and recovery-oriented services require additional resources but use them sparingly: they are highly individualized, often result in reductions in costs of other mental health services, such as hospitalizations, and favour reliance on and integration into community settings rather than mental health services. Nevertheless, access to such services remains very limited. During the same period, the place of medications in the services system has become a source of growing concern, and there are several reasons to believe that current spending on medications is excessive. Inadequate housing and community supports that increase lengths of stay unnecessarily and spending on ineffective, nonrecovery-oriented vocational services are only 2 additional forms of misallocation of resources. Devolving control over medication budgets to regional or local health authorities, introducing program budgeting and marginal analysis, and implementing individual budgets to give more control to service users (in addition to promoting shared decision making) merit further investigation as potential strategies to improve outcomes for people with SMI in Canada in the context of limited budgets.

    Amartya Sen's multidimensional capability approach focuses on the importance of freedoms to be or do things people have reason to value. It is an alternative to standard utilitarian welfarism, the theoretical approach to quality-adjusted life years (QALYs) and cost-utility analyses. Despite the limitations of the utility approach in capturing non-health benefits and broader welfare inequalities, there have been very limited applications of the capability approach in the mental health context where these issues are imperative. We report the development and application of a multidimensional instrument, the OxCAP-MH, which aims to operationalise the capability approach for outcome measurement in mental health research. The study was carried out as part of an ongoing programme on community coercion experienced by service users with severe and enduring mental illness being treated using Community Treatment Orders. Capabilities data were collected at baseline in the OCTET RCT for 333 'revolving door' mental health service users who were in involuntary hospital treatment at the time of recruitment in England (2008-2011). The research focused on the identification of capabilities domains most affected by mental illness and their association with socio-demographic and clinical factors and other measures of well-being such as the EQ-5D and Global Assessment of Functioning (GAF) scales. The OxCAP-MH item response rate was 90%-68%. There were significant correlations between service users' overall capability scores and the GAF, EQ-5D VAS and EQ-5D-3L utilities (corr = 0.249, 0.514, 0.415, respectively). The most affected capability domains were: 'Daily activities', 'Influencing local decisions', 'Enjoying recreation', 'Planning one's life' and 'Discrimination'. Age had a mixed effect, while female service users and those with a primary diagnosis of schizophrenia or longer illness duration reported significantly lower capability scores. The results support the feasibility and validity of directly measuring human capabilities for the mentally ill and the potential for applying the approach to outcome measurement. PMID:24331898

    Full Text Available Two problems can be identified which counteract the need for further training: On the one hand the clientele of skilled workers is not necessarily keen on further training. On the other hand the time and cost pressure within the sector does not offer any room for time-consuming further training measures far away from the workplace. This is why the project “Virtual Learning on the building site – (Vila-b” was realized in cooperation with the project partners of the University of Bremen (Working group »Digital Media« of the Centre for Information Technology as well as from the economy (Arbeitskreis ökologischer Holzbau e. V. and Claus Holm, pm|c. The project team has tested a concept which facilitated learning adapted to the occupational reality and supported by the advantages of digital media. The central didactical elements for the development of this further training course are the contextual and methodological orientation to real work processes as well as the use of digital mobile media which facilitate learning directly at the workplace. The present article starts with a description of the theoretical basics for learning within the work process and discusses the didactical elements which are necessary for work process oriented learning with digital and mobile media.

  19. Adolescent Maternal Lifecourse Outcomes: Implications from an Integrated Mental Health Services Approach

    Directory of Open Access Journals (Sweden)

    Beth S. Russell

    2014-06-01

    Full Text Available Family intervention literature on adolescent parenting describes the pathways between outcomes for adolescent mothers and their children and the contexts of the pregnancy itself (e.g., poverty, low or no prenatal care, lower educational attainment. The aim of these descriptions is often to inform intervention designs that promote adaptive functioning for the child, the mother, and the dyad. Mental health services are an important component of many of these interventions; these services may be delivered by a clinician within the organization providing the intervention, or the organization may connect mothers with external mental health services in their communities. Using in-house clinicians rather than external providers may be beneficial by decreasing the high attrition rates common to this population. Although this service delivery approach is theoretically appealing, it has not been subject to rigorous empirical evaluation. In the current randomized study, we examine outcomes for teenage mothers based on two service delivery methods: Integrated Mental Health Services (IMHS and the Standard of Care (SoC which outsources clients’ mental health needs through community referrals. Information about the effectiveness of service delivery strategies can help program providers make decisions about how best to allocate limited funds to provide effective services.

  20. Three pedagogical approaches to introductory physics labs and their effects on student learning outcomes

    Science.gov (United States)

    Chambers, Timothy

    This dissertation presents the results of an experiment that measured the learning outcomes associated with three different pedagogical approaches to introductory physics labs. These three pedagogical approaches presented students with the same apparatus and covered the same physics content, but used different lab manuals to guide students through distinct cognitive processes in conducting their laboratory investigations. We administered post-tests containing multiple-choice conceptual questions and free-response quantitative problems one week after students completed these laboratory investigations. In addition, we collected data from the laboratory practical exam taken by students at the end of the semester. Using these data sets, we compared the learning outcomes for the three curricula in three dimensions of ability: conceptual understanding, quantitative problem-solving skill, and laboratory skills. Our three pedagogical approaches are as follows. Guided labs lead students through their investigations via a combination of Socratic-style questioning and direct instruction, while students record their data and answers to written questions in the manual during the experiment. Traditional labs provide detailed written instructions, which students follow to complete the lab objectives. Open labs provide students with a set of apparatus and a question to be answered, and leave students to devise and execute an experiment to answer the question. In general, we find that students performing Guided labs perform better on some conceptual assessment items, and that students performing Open labs perform significantly better on experimental tasks. Combining a classical test theory analysis of post-test results with in-lab classroom observations allows us to identify individual components of the laboratory manuals and investigations that are likely to have influenced the observed differences in learning outcomes associated with the different pedagogical approaches. Due to the novel nature of this research and the large number of item-level results we produced, we recommend additional research to determine the reproducibility of our results. Analyzing the data with item response theory yields additional information about the performance of our students on both conceptual questions and quantitative problems. We find that performing lab activities on a topic does lead to better-than-expected performance on some conceptual questions regardless of pedagogical approach, but that this acquired conceptual understanding is strongly context-dependent. The results also suggest that a single "Newtonian reasoning ability" is inadequate to explain student response patterns to items from the Force Concept Inventory. We develop a framework for applying polytomous item response theory to the analysis of quantitative free-response problems and for analyzing how features of student solutions are influenced by problem-solving ability. Patterns in how students at different abilities approach our post-test problems are revealed, and we find hints as to how features of a free-response problem influence its item parameters. The item-response theory framework we develop provides a foundation for future development of quantitative free-response research instruments. Chapter 1 of the dissertation presents a brief history of physics education research and motivates the present study. Chapter 2 describes our experimental methodology and discusses the treatments applied to students and the instruments used to measure their learning. Chapter 3 provides an introduction to the statistical and analytical methods used in our data analysis. Chapter 4 presents the full data set, analyzed using both classical test theory and item response theory. Chapter 5 contains a discussion of the implications of our results and a data-driven analysis of our experimental methods. Chapter 6 describes the importance of this work to the field and discusses the relevance of our research to curriculum development and to future work in physics education research.

    2015-01-01

    This book presents a computer-aided approach to the design of mechatronic systems. Its subject is an integrated modeling and simulation in a visual computer environment. Since the first edition, the simulation software changed enormously, became more user-friendly and easier to use. Therefore, a second edition became necessary taking these improvements into account. The modeling is based on system top-down and bottom-up approach. The mathematical models are generated in a form of differential-algebraic equations and solved using numerical and symbolic algebra methods. The integrated approach developed is applied to mechanical, electrical and control systems, multibody dynamics, and continuous systems. .

    At least as much time is spent solving problems addressed by application support as with actual interaction with the control system, if it is not factored into separate libraries but is coded by each programmer time and time again. Our Java libraries, called Abeans, address these issues in a communication platform independent way. Abeans perform connection management, error and timeout handling, logging, reporting, authentication, resource initialization and destruction, policy and configuration management, etc. Abeans also hide the communication details from the programmer and combine with CosyBeans, our GUI Java components, to form SCADA-like control panels. They are successfully used in such different environments such as a synchrotron light source (ANKA, Germany), an e-p collider complex (DESY, Germany), proton cyclotron (Riken, Japan) and a radio telescope (ESO, Germany). The Java library DataBush has a similar function for machine physics programs. The object oriented design of the library gives program...

    Full Text Available EntrepreneurialOrientation (EO and Strategic Decision Making (SDM have been studied in awide variety of settings. However, there is not enough research available thatcombines both topics and studies the ways in which entrepreneurs make strategicdecisions in early stages of organizational life cycle. The purpose of thisresearch was therefore to examine the effects of the factors associated withthe decision maker influencing EO and performance for two categories of firms.The results were achieved by using empirical data from two independent samplesof firms in different stages of organizational life cycle: start-up stage (n=133 and growth stage (n=173. The results show that SDM andcontrol variables have different effects in the two samples; however, for bothsamples there is significant relation between EO and performance. The paperconcludes with a discussion about the results and suggestions for futureresearch.

  4. Orientation to Value in Substantiation of Price Strategy - A New Approach of the Modern Enterprise

    Directory of Open Access Journals (Sweden)

    Cristian - Marian Barbu

    2015-06-01

    Full Text Available Price can be considered a source of messages, set up in clues relating to the characteristics of the product it targets. How these messages are received, coded and interpreted by consumers should be a major preoccupation for decision-makers. If it knows the perception of the price, the enterprise can harness its psychological potential. In justification of the decisions, the enterprise should adopt a proactive vision enabling anticipation of competition or customers at the prices charged by it. Strategic marketing planning must act in such a way to effectively manage the uncertainty that governs decisions concerning the price. The provider should focus on the value offered to consumers, the concept around which should gravitate the marketing strategy of the enterprise. Priority orientation towards costs at the expense of focus on the market does not allow for proactive price management. In this context, the need to consider the concept of value before anything else.

  5. An inheritance complexity metric for object-oriented code: A cognitive approach

    2011-06-01

    Software metrics should be used in order to improve the productivity and quality of software, because they provide critical information about reliability and maintainability of the system. In this paper, we propose a cognitive complexity metric for evaluating design of object-oriented (OO) code. The proposed metric is based on an important feature of the OO systems: Inheritance. It calculates the complexity at method level considering internal structure of methods, and also considers inheritance to calculate the complexity of class hierarchies. The proposed metric is validated both theoretically and empirically. For theoretical validation, principles of measurement theory are applied since the measurement theory has been proposed and extensively used in the literature as a means to evaluate the software engineering metrics. We applied our metric on a real project for empirical validation and compared it with Chidamber and Kemerer (CK) metrics suite. The theoretical, practical and empirical validations and the comparative study prove the robustness of the measure.

    Full Text Available Abstract Background It is well-known that health care workers in today’s general hospitals have to deal with high levels of job demands, which could have negative effects on their health, well-being, and job performance. A way to reduce job-related stress reactions and to optimize positive work-related outcomes is to raise the level of specific job resources and opportunities to recover from work. However, the question remains how to translate the optimization of the balance between job demands, job resources, and recovery opportunities into effective workplace interventions. The aim of the DISCovery project is to develop and implement tailored work-oriented interventions to improve health, well-being, and performance of health care personnel. Methods/Design A quasi-experimental field study with a non-equivalent control group pretest-posttest design will be conducted in a top general hospital. Four existing organizational departments will provide both an intervention and a comparison group. Two types of research methods are used: (1 a longitudinal web-based survey study, and (2 a longitudinal daily diary study. After base-line measures of both methods, existing and yet to be developed interventions will be implemented within the experimental groups. Follow-up measurements will be taken one and two years after the base-line measures to analyze short-term and long-term effects of the interventions. Additionally, a process evaluation and a cost-effectiveness analysis will be carried out. Discussion The DISCovery project fulfills a strong need for theory-driven and scientifically well-performed research on job stress and performance interventions. It will provide insight into (1 how a balance between job demands, job resources, and recovery from work can be optimized, (2 the short-term and long-term effects of tailored work-oriented effects, and (3 indicators for successful or unsuccessful implementation of interventions.

    Background. The purpose of this study of preterm infants was to test the effect of four approaches to the time of transition from gavage to full oral feedings, time to discharge, and weight gain during the transition. Methods. A randomized experimental design was used with four intervention groups: early start (32 weeks' postmenstrual age)/slow progressing experience (gradually increasing oral feedings offered per day); early start/maximum experience (oral feedings offered at every feeding opportunity); late start (34 weeks' postmenstrual age)/slow progressing experience; and late start/maximum experience. Results. The analysis included 86 preterm infants. Once oral feedings were initiated, infants in the late start/maximum experience group achieved full oral feeding and were discharged to home significantly sooner than infants in either early start group. Although not significantly different, these infants also achieved these outcomes sooner than infants in the late start/slow progressing experience group. There were no differences in weight gain across groups. Conclusions. Results suggest starting oral feedings later in preterm infants may result in more rapid transition to full oral feedings and discharge although not at early postnatal ages. Provision of a more consistent approach to oral feeding may support infant neurodevelopment and reduce length of hospitalization. PMID:26000176

    Full Text Available Psilocybin is a substance of natural origin, occurring in hallucinogenic mushrooms (most common in the Psilocybe family. After its synthesis in 1958 research began on its psychoactive properties, particularly strong effects on visual perception and spatial orientation. Due to the very broad spectrum of psilocybin effects research began on the different ranges of its actions – including the effect on physiological processes (such as eye saccada movements. Neuro-imaging and neurophysiological research (positron emission tomography - PET and electroencephalography - EEG, indicate a change in the rate of metabolism of the brain and desync cerebral hemispheres. Experimental studies show the changes in visual perception and distortion from psilocybin in the handwriting style of patients examined. There are widely described subjective experiences reported by the subjects. There are also efforts to apply testing via questionnaire on people under the influence of psilocybin, in the context of the similarity of psilocybin-induced state to the initial stages of schizophrenia, as well as research aimed at creating an ‘artificial’ model of the disease.

    2006-04-01

    Full Text Available Abstract Background Recent studies on representative samples of psychiatric services have shown that low proportions of cases received effective rehabilitation interventions. The following are likely to be the most important causes: the scarcity of mental health workers trained in social and work skills strategies and the absence of a structured framework to formulate rehabilitation practices. The aim of this study was to assess if a specific structured planning and evaluation manual, called VADO (Valutazione delle Abilità e Definizione degli Obiettivi – in english: Skills Assessment and Definition of Goals, is more effective than routine interventions in reducing disability in patients with schizophrenia. Method Each of 10 mental health services were invited to recruit 10 patients with a schizophrenic disorder. Altogether 98 patients were recruited. Of these, 62 patients were randomly allocated to the intervention/experimental or a control group. The remaining group of 36 patients was not randomised and it was considered as a parallel effectiveness study. Assessment measures at the beginning of the study and at the one-year follow-up included the FPS scale of social functioning and the BPRS 4.0. Between group (VADO vs. Routine and time effects were examined with ANOVA, Chi-square or Fisher exact. Clinical "improvement" was defined as an increase of at least ten points on the FPS or a decrease of at least 20% on BPRS scores. Results 31 of the 62 randomized patients received the experimental interventions, while 31 followed the routine ones. At follow-up, the experimental group showed statistically and clinically greater improvements in psychopathology and social functioning. Better outcomes of both social functioning and symptom severity were observed in non randomised patients (parallel effectiveness study. Conclusion The results suggest that setting personalised and measurable objectives, as recommended by the manual, can improve the outcome of rehabilitation of severe mental disorders. Better outcomes in the parallel effectiveness study could be attributed to the greater confidence and enthusiasm of staff in centres where the VADO approach originated.

    Diencephalic syndrome (DS) is a clinical disorder of metabolism associated with poor outcome in children with low-grade gliomas (LGGs). Since survival has been primarily reported with aggressive therapy, we report outcome data for these patients using a current, contrasting chemotherapy-driven approach. We performed a population-based review of DS patients treated with chemotherapy from 1997-2012. Metabolic rate was assessed in selected cases using open-circuit calorimetry to generate resting energy expenditure (REE) data. Tumor tissue was analyzed for BRAF alterations. Survival was compared with an age-related, radiotherapy naïve cohort of non-DS children with location-matched LGGs. Nine children (1.7% of 520 LGG diagnoses) fulfilled DS criteria. The median diagnostic age was 1.49 years (0.55-2.69 years), although neurofibromatosis Type-I patients were older (p = 0.005). All tumors analyzed exhibited either NF1 mutation or BRAF fusion. Seven tumors were histologically confirmed as low grade astrocytomas, one demonstrated neurocytic features, and one NF1 case was diagnosed using imaging and clinical criteria. All patients received chemotherapy, with seven cases also receiving initial nutritional supplementation. All nine gained weight after only 6 months of treatment. Two DS patients had serial REE measurements, revealing a hypermetabolic state (over 200% of predicted REE) at diagnosis which reduced to normal range with therapy. First-line chemotherapy treatment resulted in one minor response, stable disease in four cases, with progression in the remaining four patients. Although DS patients demonstrated inferior initial progression-free survival when compared to non-DS counterparts (5 years: 22 versus 60%, p = 0.015), all DS children remain alive at a median follow up of 5.3 years (1.2-14.9 years) with none requiring radiotherapy. Long-term sequelae included pituitary and visual dysfunction, learning difficulties and paradoxical, inappropriate weight gain. DS can be managed with non-aggressive chemotherapeutic, radiation-sparing strategies supplemented by temporary nutritional support. Multiple lines of therapy may be required to overcome disease progression but excellent survival and metabolic outcomes can be achieved. Continued surveillance is mandatory to prevent significant weight gain and support affected children with clinical sequelae. PMID:24218181

    2012-12-01

    Full Text Available Today, Business Process Management (BPM has established itself as an important cross-functional task in companies. The primary goal of BPM is to optimize the business process design and henceforth the actual execution of business processes. However, since optimizing processes on paper is not sufficient to really boost a company’s performance, it is indispensable to optimize the process execution which defines how business processes are actually performed at the end of the day. Yet before employees are able to carry out processes, they need a given up-front learning time. Hence, to research how business process learning can be realized on-the-job is promising in order to reduce up-front learning time; thus, being able to work efficiently on processes already from the very beginning. In this paper we present a tool-supported approach towards business process learning on-the-job using the concepts of task guidance and process guidance. After introducing the approach and its prototypical implementation, the paper presents an empirical study of this prototype showing that the general approach is useful to optimize workplace learning.

Although the latter condition may be referred to surgery, drug therapy is usually the first approach to control pain. This study compared the clinical outcome and direct costs of (1 a traditional treatment (carbamazepine [CBZ] in monotherapy [CBZ protocol], (2 the association of gabapentin (GBP and analgesic block of trigger-points with ropivacaine (ROP (GBP+ROP protocol, and (3 a common TN surgery, microvascular decompression of the trigeminal nerve (MVD protocol. Sixty-two TN patients were randomly treated during 4 weeks (CBZ [n = 23] and GBP+ROP [n = 17] protocols from cases of idiopathic TN, or selected for MVD surgery (n = 22 due to intractable pain. Direct medical cost estimates were determined by the price of drugs in 2008 and the hospital costs. Pain was evaluated using the Numerical Rating Scale (NRS and number of pain crises; the Hospital Anxiety and Depression Scale, Sickness Impact Profile, and satisfaction with treatment and hospital team were evaluated. Assessments were performed at day 0 and 6 months after the beginning of treatment. All protocols showed a clinical improvement of pain control at month 6. The GBP+ROP protocol was the least expensive treatment, whereas surgery was the most expensive. With time, however, GBP+ROP tended to be the most and MVD the least expensive. No sequelae resulted in any patient after drug therapies, while after MDV surgery several patients showed important side effects. Data reinforce that, (1 TN patients should be carefully evaluated before choosing therapy for pain control, (2 different pharmacological approaches are available to initiate pain control at low costs, and (3 criteria for surgical interventions should be clearly defined due to important side effects, with the initial higher costs being strongly reduced with time.Keywords: trigeminal neuralgia, carbamazepine, gabapentin associated with ropivacaine, microvascular decompression, clinical outcomes, direct costs 

  6. Content-oriented Approach to Organization of Theories and Its Utilization

    Science.gov (United States)

    Hayashi, Yusuke; Bourdeau, Jacqueline; Mizoguch, Riichiro

    In spite of the fact that the relation between theory and practice is a foundation of scientific and technological development, the trend of increasing the gap between theory and practice accelerates in these years. The gap embraces a risk of distrust of science and technology. Ontological engineering as the content-oriented research is expected to contribute to the resolution of the gap. This paper presents the feasibility of organization of theoretical knowledge on ontological engineering and new-generation intelligent systems based on it through an application of ontological engineering in the area of learning/instruction support. This area also has the problem of the gap between theory and practice, and its resolution is strongly required. So far we proposed OMNIBUS ontology, which is a comprehensive ontology that covers different learning/instructional theories and paradigms, and SMARTIES, which is a theory-aware and standard-compliant authoring system for making learning/instructional scenarios based on OMNIBUS ontology. We believe the theory-awareness and standard-compliance bridge the gap between theory and practice because it links theories to practical use of standard technologies and enables practitioners to easily enjoy theoretical support while using standard technologies in practice. The following goals are set in order to achieve it; computers (1) understand a variety of learning/instructional theories based on the organization of them, (2) utilize the understanding for helping authors' learning/instructional scenario making and (3) make such theoretically sound scenarios interoperable within the framework of standard technologies. This paper suggests an ontological engineering solution to the achievement of these three goals. Although the evaluation is far from complete in terms of practical use, we believe that the results of this study address high-level technical challenges from the viewpoint of the current state of the art in the research area of artificial intelligence not only in education but also in general, and therefore we hope that constitute a substantial contribution for organization of theoretical knowledge in many other areas.

  7. Resignation, goal orientation and cultural essentialism in practitioners’ approaches to childhood overweight

    DEFF Research Database (Denmark)

    Ditlevsen, Kia; Nielsen, Annemette Ljungdalh

    Childhood obesity has been an increasing problem in the Western world during the second half of the 20th Century and poses a great public health challenge with no signs of reversal. The highest rates of overweight are to be found among groups with low socio-economic status and among immigrant populations from non-Western countries. Most research on interventions to counter early overweight has focused on parents’ role, and little knowledge exists on how health care professionals approach the problem and the families involved. The purpose of this study is to explore these perspectives and analyze how approaches might affect treatment, especially of underprivileged, high-risk groups among pre-school children. This study is based on qualitative research interviews with 20 Danish health care professionals, working with interventions targeted overweight pre-school children. Field work was exploratory and a grounded theory approach was adopted. Interviews were recorded and transcribed verbatim. Audio and transcripts has been compared to ensure the quality. The first phase of the data analysis was exploratory as well and topics appearing in interviews structured a preliminary analysis. Afterwards all interviews were coded in NVivo by nodes defined by the initial results to secure validity and reliability. The findings suggest that professionals’ understandings of early overweight are shaped by a shared discourse on appropriate parenting (echoing the scientific model of parenting styles): Parents to overweight pre-school children are seen as incapable to act demanding. Parental incapability was perceived to be greatest among ethnic minorities and the discourse of parenting was entangled with a cultural essentialism. Culture was seen as a barrier for change, and this created a reluctance to start interventions. Cultural essentialism was for some professionals combined with a Sociological resignation: A strong sense of the hardships related to migration and underprivileged status, seemed to create a sense of powerlessness among professionals.

    This preliminary study evaluated the relationship between therapy process variables (mechanistic processes and interpersonal processes), and treatment outcome (i.e., retention and cocaine abstinence) among 16 cocaine-dependent pregnant or postpartum women treated with the Community Reinforcement Approach (CRA). Two new rating scales were developed for this purpose. The Mechanisms of Action Rating Scale (MARS) assesses five CRA mechanistic domains (Big Picture goals, functional analyses of behavior, nondrug-related activities, skills training, and homework). The Interpersonal Variables Rating Scale (IVRS) measures three nonspecific or interpersonal dimensions of psychotherapy (i.e., empathy, response to resistance, and therapeutic alliance). These rating scales were used to rate one, early treatment, videotaped CRA session for each subject. Results indicated that: 1) sessions with patients who achieved three or more consecutive weeks of cocaine abstinence were rated significantly higher on therapist empathy and positive responses to resistance, and total IVRS scores (all of which indicate positive interpersonal processes); and 2) Big Picture goals, positive therapeutic alliance, and total IVRS scores were significantly and positively correlated with number of consecutive weeks of cocaine-negative urine toxicology tests. Only MARS homework scores were significantly and positively associated with number of study weeks completed. Finally, the pattern of interrelationships among the MARS subdomains suggests the coherence of the multifaceted CRA treatment. The findings of this preliminary study suggest the importance of monitoring both mechanistic and interpersonal processes during CRA treatment of cocaine dependence. PMID:15230080

    Full Text Available À partir d’une thèse qui affirme l’irréductibilité du sujet de la parole aux figures du soi-même que fomente le récit autobiographique, l’auteur montre comment la mise en récit produit cet effet de subjectivation. Parce que le sujet de l’acte de dire ne peut qu’être exclu des énoncés qu’il articule, lui est ouvert l’horizon des possibles constitutifs de son projet d’exister. C’est sur la base de tels principes que peuvent se déduire les traits significatifs des dispositifs de formation et de recherche que nous promouvons dans le champ des pratiques autobiographiques. Les outils d’analyse et d’interpré­tation que nous proposons permettent de développer une véritable clinique textuelle. “Approche clinique” ne signifie cependant pas que la méthode du récit autobiographique relève nécessairement des pratiques thérapeutiques. Ses domaines d’application sont pluriels et les passages de frontières méritent d’être bien repérés. Le mouvement de la réflexion s’achève par une mise en cause sévère de certains usages de la notion d’identité pour rendre compte des effets de transformation repérables en formation, en thérapie ou en psychanalyse. Nous soutenons que c’est en raison de la non-identité de soi à soi que le sujet opère les changements qui pourront le rapprocher de sa quête. Pour ne pas conclure, nous terminons le récit de notre itinéraire dans le monde du récit autobiographique en proposant deux axes de recherches.Based on a thesis affirming the irreducibility of the subject of speech to the figures of oneself the autobiographical narrative foments, the author shows how the setting in narrative produces the effect of subjectification. Since the subject of the act of speaking cannot but be excluded from the statements he makes, the horizon of possibilities constitutive of his project of existing opens out to him. The significant features of the training and research techniques we promote in the field of autobiographical practices can be deduced on the basis of such principles. The analytical and interpretational tools we propose facilitate the development of a veritable textual clinic. However, a “clinical approach” does not mean that the method of autobiographical narrative necessarily involves therapeutic practices. Its areas of application are plural and the border crossings deserve to be delineated. This reflective process is brought to a close with a severe challenge against certain uses of the notion of identity to account for transformational effects noted in training, therapy or psychoanalysis. We contend that it is because of the non-identity of self to self that the subject brings to bear the chan­ges capable of bringing him nearer to his goal. In order not to conclude, we close the narrative of our journey into the world of autobiographical narrative in proposing two research orientations.

    2015-11-01

    The Research Domain Criteria Project suggests to base the classification of mental disorders on dimensions of observable behavior and neurobiological measures of these functions rather than on symptom-based descriptive categorical diagnoses. We suggest a mechanistic approach that focuses on the role of learning as a core mechanism that can be studied in animals and humans. We review human studies on neurobiological, psychophysiological, and behavioral correlates of Pavlovian associative learning and delineate commonalities and differences across disorders. In addition to the hedonic value, the learning phase (i.e. habituation, acquisition, extinction, extinction recall), the role of stimulus properties (i.e., cue and context), and event timing (e.g. delay and trace conditioning) were considered. We address how core behavioral and psychophysiological indicators of conditioning, such as contingency ratings and skin conductance responses or startle modulation, respectively, are altered. We also discuss plastic changes in core brain regions and the interaction of brain regions in inhibitory and excitatory circuits. We also address the translation of findings pertaining to classical conditioning and its affiliated processes into the development of new behavioral and pharmacological treatments for mental disorders, and discuss productive avenues for future studies.

    Process chains in manufacturing consist of multiple connected processes in terms of dynamic systems. The properties of a product passing through such a process chain are influenced by the transformation of each single process. There exist various methods for the control of individual processes, such as classical state controllers from cybernetics or function mapping approaches realized by statistical learning. These controllers ensure that a desired state is obtained at process end despite of variations in the input and disturbances. The interactions between the single processes are thereby neglected, but play an important role in the optimization of the entire process chain. We divide the overall optimization into two phases: (1) the solution of the optimization problem by Dynamic Programming to find the optimal control variable values for each process for any encountered end state of its predecessor and (2) the application of the optimal control variables at runtime for the detected initial process state. The optimization problem is solved by selecting adequate control variables for each process in the chain backwards based on predefined quality requirements for the final product. For the demonstration of the proposed concept, we have chosen a process chain from sheet metal manufacturing with simplified transformation functions.

    Full Text Available Magnetic Resonance Imaging (MRI has brought in several benefits to the study of Multiple Sclerosis (MS. It provides accurate measurement of disease activity, facilitates precise diagnosis, and aid in the assessment of newer therapies. The imaging guidelines for MS are broadly divided in to approaches for imaging patients with suspected MS or clinically isolated syndromes (CIS or for monitoring patients with established MS. In this review, the technical aspects of MR imaging for MS are briefly discussed. The imaging process need to capture the twin aspects of acute MS viz. the autoimmune acute inflammatory process and the neurodegenerative process. Gadolinium enhanced MRI can identify acute inflammatory lesions precisely. The commonly applied MRI marker of disease progression is brain atrophy. Whole brain magnetization Transfer Ratio (MTR and Magnetic Resonance Spectroscopy (MRS are two other techniques use to monitor disease progression. A variety of imaging techniques such as Double Inversion Recovery (DIR, Spoiled Gradient Recalled (SPGR acquisition, and Fluid Attenuated Inversion Recovery (FLAIR have been utilized to study the cortical changes in MS. MRI is now extensively used in the Phase I, II and III clinical trials of new therapies. As the technical aspects of MRI advance rapidly, and higher field strengths become available, it is hoped that the impact of MRI on our understanding of MS will be even more profound in the next decade.

    Full Text Available In the paper there are presented system approaches, applied in Slovak transformed production enterprises, which solve questions of closing the so called industrial cycle from the side of the wastes' producers. The production quality is connected not only with the technological chain itself and with outputs from it - the utility product, but also with the load of the life environment.The presented possibilities of the liquidation of solid energetic waste – fly ashes – represent a an overview of forms and methods of its utilization. By combusting one kind of coal in various boilers, fly ashes with different physical, chemical, and mineralogical properties originate, with the combustion temperature as a dominant factor. The fly ashes are directly (without influencing its composition applied in civil engineering, mining, metallurgy, waste water cleaning, etc. Their utilization after a separation removal of unwanted components is an economically difficult process. Such a unvaluable component is coal combustion residue, evaluated by the annealing loss (carbon-in-ash loss in fly ashes used for special procedures in civil enginering, e.g. in mortars (maximally 4% of c.a.s. loss or in the porous concrete (4-7% of c.a.s. loss. The building industry processes about 20% of solid energetic waste.

  18. Constraints on the retreat from a welfare-orientated approach to public health care in Malaysia.

    1999-04-01

    Both in its articulation of values and through incremental changes, the Malaysian government has signalled a change in attitude towards the welfare approach which had hitherto characterized public health care policy. This change envisions an end to reliance upon the state for the provision and financing of health services and the fostering of a system of family-based welfare. In the future citizens should finance their own health care through savings, insurance or as part of their terms of employment. While the state will still accept a degree of responsibility for those unable to pay for their health care, it wishes to share this burden with the corporate sector and non-government organizations as part of a national policy of the 'Caring Society'. In this article the retreat from a commitment to a welfare model of public health care is documented and some of the serious obstacles to such a policy are discussed. It is concluded that the government's aspirations for reforming the welfare model will need to be tempered by both practical and political considerations. Moreover, the socio-economic consequences of the Asian currency crisis of 1997 are likely to increase the need for government welfare action. PMID:10387810

    Water quality management and load reduction are subject to inherent uncertainties in watershed systems and competing decision objectives. Therefore, optimal decision-making modeling in watershed load reduction is suffering due to the following challenges: (a) it is difficult to obtain absolutely "optimal" solutions, and (b) decision schemes may be vulnerable to failure. The probability that solutions are feasible under uncertainties is defined as reliability. A reliability-oriented multi-objective (ROMO) decision-making approach was proposed in this study for optimal decision making with stochastic parameters and multiple decision reliability objectives. Lake Dianchi, one of the three most eutrophic lakes in China, was examined as a case study for optimal watershed nutrient load reduction to restore lake water quality. This study aimed to maximize reliability levels from considerations of cost and load reductions. The Pareto solutions of the ROMO optimization model were generated with the multi-objective evolutionary algorithm, demonstrating schemes representing different biases towards reliability. The Pareto fronts of six maximum allowable emission (MAE) scenarios were obtained, which indicated that decisions may be unreliable under unpractical load reduction requirements. A decision scheme identification process was conducted using the back propagation neural network (BPNN) method to provide a shortcut for identifying schemes at specific reliability levels for decision makers. The model results indicated that the ROMO approach can offer decision makers great insights into reliability tradeoffs and can thus help them to avoid ineffective decisions. PMID:25688523

  20. A set cover approach to fast beam orientation optimization in intensity modulated radiation therapy for total marrow irradiation

    International Nuclear Information System (INIS)

    The beam orientation optimization (BOO) problem in intensity modulated radiation therapy (IMRT) treatment planning is a nonlinear problem, and existing methods to obtain solutions to the BOO problem are time consuming due to the complex nature of the objective function and size of the solution space. These issues become even more difficult in total marrow irradiation (TMI), where many more beams must be used to cover a vastly larger treatment area than typical site-specific treatments (e.g., head-and-neck, prostate, etc). These complications result in excessively long computation times to develop IMRT treatment plans for TMI, so we attempt to develop methods that drastically reduce treatment planning time. We transform the BOO problem into the classical set cover problem (SCP) and use existing methods to solve SCP to obtain beam solutions. Although SCP is NP-Hard, our methods obtain beam solutions that result in quality treatments in minutes. We compare our approach to an integer programming solver for the SCP to illustrate the speed advantage of our approach.

  1. [Usability first. Model-based approach for the use-oriented risk analysis of medical devices].

    2014-12-01

    Due to increasing automation, the number and complexity of technical components have increased in the medical context (e.g., in the clinic or in the home care sector) in recent years. Besides new effective and efficient therapeutic and diagnostic options, these devices entail a wide range of functions and very complex (often computer-based) user interfaces that may lead to human-induced risk potential. A systematic and early human risk analysis and a usability evaluation allow medical device manufacturers to identify and control risks within the human-machine interaction very efficiently. At the Department of Medical Engineering in the Helmholtz Institute for Biomedical Engineering at the RWTH Aachen University, a formal-analytical methodology and a corresponding software tool for prospective human-risk analysis and model-based usability evaluation has been developed. Based on a twofold approach, user interactive process sequences and their potential impacts on the overall process are identified and the resulting use-related risks are assessed. For this, the tasks are categorized (in system and user tasks) and modeled and temporally related within the framework of a high-level task analysis. Within a subsequent cognitive low-level task analysis, potentially critical parallel process sequences are then tested in order to detect a potential resource overload of the user. The subsequent corresponding human-risk analysis is developed according to a knowledge base (checklist) of taxonomies related to human error. The HiFEM (human-function effect modeling) methodology is universally applicable and can be used for the evaluation of human-computer interfaces as well as for the analysis of purely mechanical control interfaces and simple hand-held instruments (such as a scalpel and implant). In a comparative study, the HiFEM method clearly outperforms the classic FMEA (failure modes and effects analysis) process with regard to effectiveness, efficiency, learnability, and user satisfaction. Especially small and medium-sized enterprises that constitute the medical device industry can be supported by the new methodology in the context of risk management according to ISO 14971 as well as usability engineering in accordance with IEC 62366 and IEC 60601-1-6 as well as EN ISO 9241.

  2. The prediction of breast cancer biopsy outcomes using two CAD approaches that both emphasize an intelligible decision process

    International Nuclear Information System (INIS)

    Mammography is the most effective method for breast cancer screening available today. However, the low positive predictive value of breast biopsy resulting from mammogram interpretation leads to approximately 70% unnecessary biopsies with benign outcomes. To reduce the high number of unnecessary breast biopsies, several computer-aided diagnosis (CAD) systems have been proposed in the last several years. These systems help physicians in their decision to perform a breast biopsy on a suspicious lesion seen in a mammogram or to perform a short term follow-up examination instead. We present two novel CAD approaches that both emphasize an intelligible decision process to predict breast biopsy outcomes from BI-RADS findings. An intelligible reasoning process is an important requirement for the acceptance of CAD systems by physicians. The first approach induces a global model based on decison-tree learning. The second approach is based on case-based reasoning and applies an entropic similarity measure. We have evaluated the performance of both CAD approaches on two large publicly available mammography reference databases using receiver operating characteristic (ROC) analysis, bootstrap sampling, and the ANOVA statistical significance test. Both approaches outperform the diagnosis decisions of the physicians. Hence, both systems have the potential to reduce the number of unnecessary breast biopsies in clinical practice. A comparison of the performance of the proposed decision tree and CBR approaches with a state of the art approach based on artificial neural networks (ANN) shows that the CBR approach performs slightly better than the ANN approach, which in turn results in slightly better performance than the decision-tree approach. The differences are statistically significant (p value <0.001). On 2100 masses extracted from the DDSM database, the CRB approach for example resulted in an area under the ROC curve of A(z)=0.89±0.01, the decision-tree approach in A(z)=0.87±0.01, and the ANN approach in A(z)=0.88±0.01

  6. Paying for On-Patent Pharmaceuticals: Limit Prices and the Emerging Role of a Pay for Outcomes Approach.

    Science.gov (United States)

    Fuller, Richard L; Goldfield, Norbert

    2016-01-01

    In this article we propose a new approach to pricing for patent-protected (on-patent) pharmaceuticals. We describe and define limit pricing as a method for drug companies to maximize revenue for their investment by offering budget-neutral pricing to encourage early adoption by payers. Under this approach, payers are incentivized to adopt innovative but expensive drugs more quickly if drug companies provide detailed analyses of the net impact of the new pharmaceutical upon total health budgets. For payers to adopt use of a new pharmaceutical, they would require objective third-party evaluation and pharmaceutical manufacturer accountability for projected outcomes efficacy of their treatments on population health. The pay for outcomes underpinning of this approach falls within the wider aspirations of health reform. PMID:26945298

    2015-04-01

    Recent evidence attests to the shortcomings of typical services for improving outcomes among emerging adults with serious mental health conditions (SMHCs). Researchers and providers have responded by developing new programs and interventions for meeting the unique needs of these young people. A significant number of these programs and interventions can be described as taking a positive developmental approach, which is informed by a combination of theoretical sources, including theories of positive development, self-determination, ecological systems, and social capital. To date, however, there has been no comprehensive theoretical statement describing how or why positive change should occur as a result of using a positive developmental approach when intervening with this population. The goal of this article is to propose a general model that "backfills" a theory behind what appears to be an effective and increasingly popular approach to improving outcomes among emerging adults with SMHCs.

    A sustained first inflation (SI) at birth may aid lung liquid clearance and aeration, but the impact of SI duration relative to the volume-response of the lung is poorly understood. We compared three SI strategies: 1) variable duration defined by attaining volume equilibrium using real-time electrical impedance tomography (EIT; SIplat); 2) 30 s beyond equilibrium (SIlong); 3) short 30-s SI (SI30); and 4) positive pressure ventilation without SI (no-SI) on spatiotemporal aeration and ventilation (EIT), gas exchange, lung mechanics, and regional early markers of injury in preterm lambs. Fifty-nine fetal-instrumented lambs were ventilated for 60 min after applying the allocated first inflation strategy. At study completion molecular and histological markers of lung injury were analyzed. The time to SI volume equilibrium, and resultant volume, were highly variable; mean (SD) 55 (34) s, coefficient of variability 59%. SIplat and SIlong resulted in better lung mechanics, gas exchange and lower ventilator settings than both no-SI and SI30. At 60 min, alveolar-arterial difference in oxygen was a mean (95% confidence interval) 130 (13, 249) higher in SI30 vs. SIlong group (two-way ANOVA). These differences were due to better spatiotemporal aeration and tidal ventilation, although all groups showed redistribution of aeration towards the nondependent lung by 60 min. Histological lung injury scores mirrored spatiotemporal change in aeration and were greatest in SI30 group (P < 0.01, Kruskal-Wallis test). An individualized volume-response approach to SI was effective in optimizing aeration, homogeneous tidal ventilation, and respiratory outcomes, while an inadequate SI duration had no benefit over positive pressure ventilation alone.

  9. Are students who have been educated in an outcomes-based approach prepared for university mathematics?

    Full Text Available Following the political changes of 1994 in South Africa, the decision was taken to replace the traditional skills-based education system at primary and secondary school level (Grades 1 - 12 with an outcomes-based education system (OBE. The OBE approach, referred to as Curriculum 2005, was introduced into schools in 1998. The implementation of the OBE system did not occur without problems, giving rise to revised initiatives and a fair amount of criticism. The 2009 intake of students at universities is the first group of students that had been subjected to the OBE approach for their entire school career. This is also the first group of students for whom some form of mathematics was compulsory up to Grade 12 level in the form of mathematics or mathematical literacy. These students were characterised by the fact that their mathematics marks for Grade 12 were exceptionally high and that many more students qualified for university entrance. This article reports on the impact of this new education system on the mathematics prepared-ness of students entering university. The study involves an empirical analysis of the students in the first-year mathematics course for engineering students at the University of Pretoria as well as an analysis of a questionnaire completed by experienced lecturers at this university. The question addressed in this article is how the 2009 intake of students cope with mathematics at university level with regard to Performance General attributes Mathematical attributes Content-related attributesResults indicate a decrease in mathematics performance of these students at university level and that the inflated matric marks result in unjustified expectations. However, it is not unusual for marks to decrease from school to university and there is still too little evidence for serious concern. The study also indicates that these students seem to be better equipped with regard to personal attributes such as self-confidence and the will to work. However, in many instances, their general mathematical attributes such as algebraic manipulation skills and their general mastery of mathematical writing are worse than those of students in the past. There are also areas where their content knowledge is either lacking or unexpectedly shallow. It therefore appears that these students have improved personal attributes but not necessarily the knowledge and mathematical skills to back them up. Some recommendations are made with regard to handling the situation. It is clear that the new school system necessitates changes at school level with a view to university level in order to ensure a transition that is surmountable.

  10. Wisdom as outcome of the pastoral process: Reflections on a positive pastoral narrative approach

    Directory of Open Access Journals (Sweden)

    Alfred R. Brunsdon

    2015-02-01

    Full Text Available From a South African perspective, pastoral care is typically concerned with the solving or resolving of critical issues such as marital crises or depression. It represents an approach that is based on a medical or disease model, addressing deficits rather than strengths in the lives of counselees. Therapeutic developments in the fields of the narrative approach and positive psychology have shifted the attention to the therapeutic nurturing of liberating stories and the strengthening of virtues. Thus, the quality of the human experience by capitalising on what is healthy and intact is enhanced. This article will explore the notion that the pastoral process should aim at understanding and nurturing emotional and spiritual strengths with wisdom as the outcome, rather than trying to unravel spiritual deficits as strategy for healing. Such a positive approach relies on wisdom as a foundational virtue. By cultivating wisdom, counselees become fit for a well-lived life. In light of this, the necessity for widening our traditional pastoral horizons is discussed. Scripture and positive psychology are considered as sources to inform the pastoral process on wisdom and the narrative is discussed as a means to uncover and cultivate wisdom in the lives of counselees. Markers for a positive pastoral narrative approach, aimed at the cultivation of wisdom, are suggested. This article endeavours to contribute to the enrichment of pastoral practitioners’ frame of reference by drawing on the insights of neighbouring helping-disciplines, like the narrative and positive psychology employed within a practical theological paradigm, hence contributing to the ongoing call (semper reformanda to always renew our theological endeavours.Wysheid as uitkoms van die pastorale proses: Nadenke oor ’n positiewe pastoraal-narratiewe benadering. Vanuit ’n Suid Afrikaanse perspektief is pastorale sorg tipies op die oplossing van probleme soos huwelikskonflik of depressie gerig. As sodanig verteenwoordig dit ’n benadering wat op ’n mediese of siektemodel gegrond is en op gebreke eerder as deugde van persone gerig is. Terapeutiese ontwikkelings op die terreine van die narratief en positiewe sielkunde het egter die aandag op die gebruik van bevrydende verhale en die versterking van deugde gevestig. Sodoende word die kwaliteit van die menslike bestaan verbeter deur voort te bou op dít wat gesond en ongeskonde in mense se lewens is. In hierdie artikel word die opvatting ondersoek dat die pastorale proses op die verstaan en kweek van geestelike en emosionele deugde gerig moet wees eerder as op die verstaan en ontknoping van probleme as strategie vir genesing – spesifiek met die deug van wysheid in gedagte. Só ’n benadering berus op die aanname dat wysheid ’n deug is wat persone vir die lewe bemagtig. Die versterking van wysheid rus mense vir ’n vervulde lewe toe. In die lig hiervan word die noodsaaklikheid om bestaande pastorale verwysingsraamwerke te verbreed, bespreek. Die Skrif en die positiewe sielkunde word as bronne van kennis oor wysheid oorweeg en die narratief as ’n metode om wysheid in die lewens van die beradenes bloot te lê en verder te ontwikkel. Aanwysings vir ’n positiewe pastoraal-narratiewe benadering wat op die ontwikkeling van wysheid gemik is, word gegee.

  12. Conceptual model for assessing criteria air pollutants in a multipollutant context: A modified adverse outcome pathway approach.

    Buckley, Barbara; Farraj, Aimen

    2015-09-01

    Air pollution consists of a complex mixture of particulate and gaseous components. Individual criteria and other hazardous air pollutants have been linked to adverse respiratory and cardiovascular health outcomes. However, assessing risk of air pollutant mixtures is difficult since components are present in different combinations and concentrations in ambient air. Recent mechanistic studies have limited utility because of the inability to link measured changes to adverse outcomes that are relevant to risk assessment. New approaches are needed to address this challenge. The purpose of this manuscript is to describe a conceptual model, based on the adverse outcome pathway approach, which connects initiating events at the cellular and molecular level to population-wide impacts. This may facilitate hazard assessment of air pollution mixtures. In the case reports presented here, airway hyperresponsiveness and endothelial dysfunction are measurable endpoints that serve to integrate the effects of individual criteria air pollutants found in inhaled mixtures. This approach incorporates information from experimental and observational studies into a sequential series of higher order effects. The proposed model has the potential to facilitate multipollutant risk assessment by providing a framework that can be used to converge the effects of air pollutants in light of common underlying mechanisms. This approach may provide a ready-to-use tool to facilitate evaluation of health effects resulting from exposure to air pollution mixtures. PMID:26196529

    The assessment of medical outcomes is important in the effort to contain costs, streamline patient management, and codify medical practices. As such, it is necessary to develop predictive models that will make accurate predictions of these outcomes. The neural network methodology has often been shown to perform as well, if not better, than the logistic regression methodology in terms of sample predictive performance. However, the logistic regression method is capable of providing an explanati...

    2011-08-01

    Full Text Available The principle of separation of concerns is a basis element in the software engineering and allows for the division of properties, becoming smaller each time, so as to master their complexity, from the design phase to achievement phase. This paper proposes the probabilistic assessment of critical fault-tolerant programmed systems to improve reliability and availability of an embedded system. In addition, to improve their response time, we use separation of concerns approach, functional (behavior and non-functional (control. This phase will be achieved by developing a simulator based on aspect-oriented programming (AspectJ. The main objective is to show the impact of this separation on the response time when a hardware architecture of a processor executes instructions and routines of a software application correctly. The probabilistic assessment is based on the failure rate of software instructions executed on hardware architecture of a stack processor whose choice will be justified. The failures considered in this work are the basis of a study of decomposition and refinement carried out by the NFR Framework. As a result, this work has treated the issue of hardware / software interaction in programmed critical systems and the improvement of execution time.

    2014-02-01

    Full Text Available Multi-national enterprises (MNEs have provided substantial sponsorship for the Sochi Winter Olympic Games despite a host-country government that has recently enacted stunningly harsh legislation aimed at the Lesbian, Gay, Bisexual, Transgender, and Intersex (LGBTI communities within Russia. This is a Corporate Social Responsibility (CSR problem. Should Europe address it through voluntary corporate compliance, Europe’s historically preferred mode of promoting CSR? Or should Europe reconsider whether it can more effectively promote CSR compliance legislatively – and if so, by what kind of legislation? To honor the explicit and increased protections of human rights against sexual orientation discrimination in the Treaty of Amsterdam and the Charter of Fundamental Human Rights, more than voluntary, good intentions are needed. Particularly since the United States has effectively bowed out of enforcing CSR through the American federal courts, there now exists a regulatory lacuna that the European Commission is best situated to fill through the precision offered by judicious rulemaking. The article ultimately proposes an approach that combines the public-pressure engine that fuels voluntary CSR with public disclosures mandated by law to optimize the information and mobilization of public opinion and pressure – factors particularly noteworthy given the powerful “branding” benefits that MNEs seek through Olympic sponsorship.

    Full Text Available Unlike the open competition economic sectors where tens, hundreds or even thousands of companies ‘struggle’ to provide consumers not only with services but also with special utility, the regulated markets (power supply, public transportation, public safety etc. are dominated by a limited number of service providers. Sometimes the situation is pushed to the point where a few companies ‘control’ the market and set the prices. Although the power and gas supply is still ‘dictated’ by the Romanian authorities, the directives of the European Union coerce the government to deregulate the utility sector and liberalize prices. For the companies concerned, this entails a better customer orientation and an adaptation of their services to the customers’ expectations and preferences. From this point forward, the utility suppliers will have to better cope with the public’s various forms of dissatisfaction with prices, performance or communication etc. The authors of the current paper attempt to analyze how some characteristics of the marketing mix of utility providers may contribute to a proper understanding and building satisfaction with two surveyed regional providers. The findings reveal significant management implications which help utility providers better channel their efforts into the proper knowledge of markets and particularly the target segments that they approach.

    The treatment of torture survivors from diverse cultures has been a difficult task involving issues of loss, massive trauma, cultural style, and adjusting to a new country. Research on treatment outcomes has shown inconsistent results. This report presents a prospective one year treatment outcome of 22 severely tortured patients from Ethiopia, Somalia, Iran and Afghanistan. Treatment was provided by psychiatrists and counselors with interpreters from each culture involved. The specific treatment included psychiatric evaluation, medicine, education, supportive psychotherapy and assisting some social needs. All 22 were diagnosed with depression and 17 of these also had posttraumatic stress disorder (PTSD). Twenty of 22 patients showed marked significant improvement on all of the scales for depression, PTSD, disability, and quality of life. Medicine was particularly useful in treating depression and the symptoms of flashbacks, nightmares and irritability. Standard psychiatric treatment with evaluation, diagnosis, appropriate medicine, supportive psychotherapy and counseling by ethnic counselors provided good outcomes. PMID:23086001

  5. Implementing Optimal Outcomes in Social Computing: A Game-Theoretic Approach

    CERN Document Server

    2012-01-01

    In many social computing applications such as online Q&A forums, the best contribution for each task receives some high reward, while all remaining contributions receive an identical, lower reward irrespective of their actual qualities. Suppose a mechanism designer (site owner) wishes to optimize an objective that is some function of the number and qualities of received contributions. When potential contributors are strategic agents, who decide whether to contribute or not to selfishly maximize their own utilities, is such a "best contribution" mechanism, M_B, adequate to implement an outcome that is optimal for the mechanism designer? We first show that in settings where a contribution's value is determined primarily by an agent's expertise, and agents only strategically choose whether to contribute or not, contests can implement optimal outcomes: for any reasonable objective, the rewards for the best and remaining contributions in M_B can always be chosen so that the outcome in the unique symmetric equi...

      A revised core curriculum model for pharmaceutical education, developed on the basis of the principles of outcome-based education, will be introduced in 2015. Inevitably, appropriate assessments of students' academic achievements will be required. Although evaluations of the cognitive domain can be carried out by paper tests, evaluation methods for the attitude domain and problem-solving abilities need to be established. From the viewpoint of quality assurance for graduates, pharmaceutical education reforms have become vital to evaluation as well as learning strategies. To evaluate student academic achievements on problem-solving abilities, authentic assessment is required. Authentic assessment is the evaluation that mimics the context tried in work and life. Specifically, direct evaluation of performances, demonstration or the learners' own work with integrated variety knowledge and skills, is required. To clarify the process of graduate research, we obtained qualitative data through focus group interviews with six teachers and analyzed the data using the modified grounded theory approach. Based on the results, we clarify the performance students should show in graduate research and create a rubric for evaluation of performance in graduate research. PMID:25743905

    Understanding the complex relationship among determinants of real-world functioning in schizophrenia patients in remission is important in planning recovery-oriented interventions. We explored two path-analytical models of functioning in schizophrenia. 170 Schizophrenia patients remitted from positive symptoms underwent fairly comprehensive assessments of cognition - neurocognition (NC) and social cognition (SC), residual symptoms - insight, motivation and other negative symptoms, and socio-occupational functioning. We explored (a) a cascading model, where NC predicted functional outcome through its effects on other determinants and (b) a combined model, incorporating additional direct paths from each of the determinants. The combined model, and not the cascading model demonstrated a good fit. Post-hoc trimming of the combined model by elimination of non-significant paths maintained the goodness-of-fit and was retained as the final model. In addition to the direct paths, this final model demonstrated that (a) NC influenced functioning through SC and insight and (b) SC influenced functioning through motivation and negative symptoms. This suggests that NC and SC may influence functional outcome directly, as well as indirectly, via specific impact on insight, and motivation and negative symptoms respectively. PMID:26208988

    "Community Partners in Care (CPIC): Video Summary of Rationale, Study Approach / Implementation, and Client 6-month Outcomes" is a 2 minute, 46 second video summarizing the study rationale, study approach, and the 6-month outcomes. The video was produced by four agencies: Healthy African American Families II, a health advocacy organization in South Los Angeles; Behavioral Health Services, the largest substance/alcohol abuse service provider in LA County; UCLA; and RAND Health; contract filmmakers Eileen Cabiling and Joe Mango handled cinematography, editing, and video support. The individuals appearing in the video are key CPIC community and academic partners. The celebratory tone of the video is consistent with a Community Partnered Participatory Research approach, a local variant of participatory action research, where study findings are celebrated by the partners, and dissemination efforts include approaches intended for general audiences, especially from low-income, low-literacy, minority communities, in addition to traditional academic products like peer-reviewed scientific manuscripts. The CPIC video offers a community perspective on the study results to our partners, the general public, other scientists and policy makers. We designed the video to teach community and healthcare partners how to adapt and implement the CPIC depression care model and to offer other community -academic partnerships an example of a non-traditional product developed for dissemination from an NIH-funded research study.

    2012-04-01

    Patient-reported outcomes (PRO) are used as primary endpoints in medical research and their statistical analysis is an important methodological issue. Theoretical assumptions of the selected methodology and interpretation of its results are issues to take into account when selecting an appropriate statistical technique to analyse data. We present eight methods of analysis of a popular PRO tool under different assumptions that lead to different interpretations of the results. All methods were applied to responses obtained from two of the health dimensions of the SF-36 Health Survey. The proposed methods are: multiple linear regression (MLR), with least square and bootstrap estimations, tobit regression, ordinal logistic and probit regressions, beta-binomial regression (BBR), binomial-logit-normal regression (BLNR) and coarsening. Selection of an appropriate model depends not only on its distributional assumptions but also on the continuous or ordinal features of the response and the fact that they are constrained to a bounded interval. The BBR approach renders satisfactory results in a broad number of situations. MLR is not recommended, especially with skewed outcomes. Ordinal methods are only appropriate for outcomes with a few number of categories. Tobit regression is an acceptable option under normality assumptions and in the presence of moderate ceiling or floor effect. The BLNR and coarsening proposals are also acceptable, but only under certain distributional assumptions that are difficult to test a priori. Interpretation of the results is more convenient when using the BBR, BLNR and ordinal logistic regression approaches. PMID:20858689

    Background Blood pressure (BP) control may have different effects on cardiovascular (CV) and renal outcomes in diabetes. We examined the impact of systolic BP (SBP) on renal and CV outcomes in a post hoc analysis in the Olmesartan Reducing Incidence of Endstage Renal Disease in Diabetic Nephropathy Trial. Methods We stratified mean follow-up SBP into three categories (?130, 131–140 and >140 mmHg) and used a Cox regression model to estimate the hazard ratio (HR, 95% confidence interval) for the outcomes. The composite renal outcome was doubling of serum creatinine, end-stage renal disease and all-cause death. The composite CV outcome included CV death, nonfatal stroke, nonfatal myocardial infarction, hospitalization for unstable angina or heart failure, revascularization and lower extremity amputation. We also compared the slope of estimated glomerular filtration rate (eGFR) in all three groups. Results After a mean follow-up period of 3.2 years, the follow-up SBP was linearly associated with risk of renal outcomes in all 566 patients. In patients with heavy proteinuria (?1 g/gCr), a follow-up SBP > 130 mmHg was associated with an HR of 2.33 (1.62–3.36) for renal outcomes with referent to SBP ? 130 mmHg. In patients without history of CV disease, a follow-up SBP > 140 mmHg was associated with an HR of 2.04 (1.23–3.40) for CV outcomes with referent to SBP 140 mmHg, respectively (P = 0.008 between ?130 and 131–140, P 140 mmHg). Conclusion In Asian type 2 diabetic patients with chronic kidney disease and heavy proteinuria, reduction of SBP ? 130 mmHg was associated with greater renoprotection than cardioprotection. However, our results emphasize the need to individualize BP targets in type 2 diabetes. PMID:26152402

    Accurate and reliable information on the spatial distribution of mangrove species is needed for a wide variety of applications, including sustainable management of mangrove forests, conservation and reserve planning, ecological and biogeographical studies, and invasive species management. Remotely sensed data have been used for such purposes with mixed results. Our study employed an object-oriented approach with the use of a lacunarity technique to identify different mangrove species and their surrounding land use and land cover classes in a tsunami-affected area of Thailand using Landsat satellite data. Our results showed that the object-oriented approach with lacunarity-transformed bands is more accurate (over-all accuracy 94.2%; kappa coefficient = 0.91) than traditional per-pixel classifiers (overall accuracy 62.8%; and kappa coefficient = 0.57).

    Health counseling is an essential part of health promotion and there is a need for new, family-oriented health counseling methods. The objective of this study was to describe the differences in physical activity conversations from the perspective of family-oriented care between child health visits using the Weighty Matter Toolkit and those using normal protocol. In total, 35 health visits were analyzed. The results indicate that the Weighty Matter Toolkit offers the child, and other family members, a better opportunity to participate to conversations, and the focus of the conversation is more diverse and based on the family's perception regarding physical activity compared to the normal protocol. Thus, the Weighty Matter Toolkit is a promising method for family-oriented health counseling. PMID:24788047

    Introduction Although psychotherapies for depression produce equivalent outcomes, individual patients respond differently to different therapies. Predictors of outcome have been identified in the context of randomized trials, but this information has not been used to predict which treatment works best for the depressed individual. In this paper, we aim to replicate a recently developed treatment selection method, using data from an RCT comparing the effects of cognitive therapy (CT) and interpersonal psychotherapy (IPT). Methods 134 depressed patients completed the pre- and post-treatment BDI-II assessment. First, we identified baseline predictors and moderators. Second, individual treatment recommendations were generated by combining the identified predictors and moderators in an algorithm that produces the Personalized Advantage Index (PAI), a measure of the predicted advantage in one therapy compared to the other, using standard regression analyses and the leave-one-out cross-validation approach. Results We found five predictors (gender, employment status, anxiety, personality disorder and quality of life) and six moderators (somatic complaints, cognitive problems, paranoid symptoms, interpersonal self-sacrificing, attributional style and number of life events) of treatment outcome. The mean average PAI value was 8.9 BDI points, and 63% of the sample was predicted to have a clinically meaningful advantage in one of the therapies. Those who were randomized to their predicted optimal treatment (either CT or IPT) had an observed mean end-BDI of 11.8, while those who received their predicted non-optimal treatment had an end-BDI of 17.8 (effect size for the difference = 0.51). Discussion Depressed patients who were randomized to their predicted optimal treatment fared much better than those randomized to their predicted non-optimal treatment. The PAI provides a great opportunity for formal decision-making to improve individual patient outcomes in depression. Although the utility of the PAI approach will need to be evaluated in prospective research, this study promotes the development of a treatment selection approach that can be used in regular mental health care, advancing the goals of personalized medicine.

  7. Motivational mechanisms and outcome expectancies underlying the approach bias towards addictive substances

    Directory of Open Access Journals (Sweden)

    2012-10-01

    Full Text Available Human behavior can be paradoxical, in that actions can be initiated that are seemingly incongruent with an individual’s explicit desires. This is most commonly observed in drug addiction, where maladaptive behavior (i.e. drug seeking appears to be compulsive, continuing at great personal cost. Approach biases towards addictive substances have been correlated with actual drug-use in a number of studies, suggesting that this measure can, in some cases, index everyday maladaptive tendencies. At present it is unclear whether this bias to drug cues is a Pavlovian conditioned approach response, a habitual response, the result of a Pavlovian-instrumental transfer process or a goal-directed action in the sense that expectancy of the rewarding effects of drugs controls approach. We consider this question by combining the theoretical framework of associative learning with the available evidence from approach bias research. Although research investigating the relative contributions of these mechanisms to the approach bias is to date relatively limited, we review existing studies and also outline avenues for future research.

    Hawkley, Louise C; Capitanio, John P

    2015-05-26

    Sociality permeates each of the fundamental motives of human existence and plays a critical role in evolutionary fitness across the lifespan. Evidence for this thesis draws from research linking deficits in social relationship--as indexed by perceived social isolation (i.e. loneliness)--with adverse health and fitness consequences at each developmental stage of life. Outcomes include depression, poor sleep quality, impaired executive function, accelerated cognitive decline, unfavourable cardiovascular function, impaired immunity, altered hypothalamic pituitary-adrenocortical activity, a pro-inflammatory gene expression profile and earlier mortality. Gaps in this research are summarized with suggestions for future research. In addition, we argue that a better understanding of naturally occurring variation in loneliness, and its physiological and psychological underpinnings, in non-human species may be a valuable direction to better understand the persistence of a 'lonely' phenotype in social species, and its consequences for health and fitness.

    The Quality in Acute Stroke Care (QASC) was a cluster randomised control trial (CRCT) which evaluated the effectiveness of evidence-based clinical treatment protocols for the management of fever, hyperglycaemia and swallowing, in conjunction with multidisciplinary team building workshops, and a standardised interactive staff education program (collectively known as the Fever, Sugar, Swallowing (FeSS) intervention) to improve patient outcomes 90-days. We found that patients cared for in stroke units who received our intervention were 15·7% more likely to be alive and independent 90 days following their stroke. They also had significantly: fewer episodes of fever, lower mean temperatures, lower mean blood glucose levels, and better screening for swallowing difficulties. PMID:22405277

    Full Text Available Longitudinal data with binary repeated responses are now widespread among clinical studies and standard statistical analysis methods have become inadequate in the answering of clinical hypotheses. Instead of such conventional approaches, statisticians have started proposing better techniques, such as the Generalized Estimating Equations (GEE approach and Generalized Linear Mixed Models (GLMM technique. In this research, we undertook a comparative study of modeling binary repeated responses using an anesthesiology dataset which has 375 patient data with clinical variables. We modeled the relationship between hypotension and age, gender, surgical department, positions of patients during surgery, diastolic blood pressure, pulse, electrocardiography and doses of Marcain-heavy, chirocaine, fentanyl, and midazolam. Moreover, parameter estimates between the GEE and the GLMM were compared. The parameter estimates, except time-after, Marcain-Heavy, and Fentanyl from the GLMM, are larger than those from GEE. The standard errors from the GLMM are larger than those from GEE. GLMM appears to be more suitable approach than the GEE approach for the analysis hypotension during spinal anesthesia.

    Minimally invasive thymectomy procedures have been proposed for nonthymomatous myasthenia gravis. However, few reports stressed that the lower invasiveness or cosmetic benefits also evaluated the rationale of a thymectomy, which is performed to remove as much thymic tissue as possible. We retrospectively reviewed 30 consecutive patients who underwent a bilateral video-assisted thoracoscopic extended thymectomy (VATET) and compared the results with those of 26 patients who underwent a transsternal extended thymectomy (TSET) to determine the amount of removed thymic tissue and clinical prognosis. The amount of blood loss during the operation for VATET (median 60 mL; range nearly 0 to 940 mL) was significantly lower as compared with that of TSET. The median weight of removed thymic tissue (37.0 g; 18.3 to 100.0 g) and remission rates (1 y: 12.5%; 3 y: 30.8%; 4 y: 44.4%) of VATET were comparable with those of TSET. The VATET group had a similar amount of thymo-fatty tissue removed and feasible clinical outcomes as compared with the TSET group, indicating that VATET provides a proper balance between less invasiveness and radical capability.

  14. Improving health and education outcomes for children in remote communities: A cross-sector and developmental evaluation approach

    Full Text Available Early childhood is one of the most influential developmental life stages. Attainments at this stage will have implications for the quality of life children experience as they transition to adulthood. Children residing in remote Australia are exposed to socioeconomic disadvantage that can contribute to developmental delays and resultant poorer education and health outcomes. Complex contributing factors in far west New South Wales have resulted in children with speech and fine motor skill delays experiencing no to limited access to allied health services for a number of decades. More recently, growing awareness that no single policy, government agency, or program could effectively respond to these complexities or ensure appropriate allied health service access for children in these communities has led to the development of the Allied Health in Outback Schools Program, which has been operational since 2009. The program is underpinned by cross-sector partnerships and a shared aspirational aim to improve the developmental outcomes of children to enhance their later life opportunities. It was identified early that the initiative had the potential to deliver mutually beneficial outcomes for communities and participating partner organisations. Over the last five years the program has been the catalyst for partnership consolidation, expansion and diversification. The developmental evaluation approach to continuous program adaptation and refinement has provided valuable insights that have informed health and education policy and enabled the program to be responsive to changing community needs, emerging policy and funding reforms. This article explores the evolution of the program partnerships, their contribution to program success and longevity, and their capacity to respond to an emergent and dynamic environment. The authors propose that a community-centred and developmental approach to program innovation and implementation in remote locations is required. This is based on the premise that contemporary linear, logic-based policy development and funding allocations, with predetermined program deliverables and outcomes, are no longer capable of responding appropriately to the complexities experienced by remote communities.

    2012-12-01

    The Pine Integrated Network: Education, Mitigation and Adaptation Project ("PINEMAP") was funded by National Institute of Food and Agriculture to produce outcomes of enhanced climate change mitigation and adaptation in planted southern pine ecosystems. The PINEMAP project leverages a strong group of existing networks to produce synergy and cooperation on applied forestry research in the region. Over the last 50 years, cooperative research on planted southern pine management among southeastern U.S. universities, government agencies, and corporate forest landowners has developed and facilitated the widespread implementation of improved genetic and silvicultural technology. The impact of these regional research cooperatives is difficult to overstate, with current members managing 55% of the privately owned planted pine forestland, and producing 95% of the pine seedlings planted each year. The PINEMAP team includes the eight major forestry cooperative research programs, scientists from eleven land grant institutions, the US Forest Service, and climate modeling and adaptation specialists associated with the multi-state SE Climate Consortium and state climate offices. Our goal is to create and disseminate the knowledge that enables landowners to: harness planted pine forest productivity to mitigate atmospheric CO2; more efficiently use nitrogen and other fertilizer inputs; and adapt their forest management to increase resilience in the face of changing climate. We integrate our team's infrastructure and expertise to: 1) develop breeding, genetic deployment and innovative management systems to increase C sequestration and resilience to changing climate of planted southern pine forests ; 2) understand interactive effects of policy, biology, and climate change on sustainable management; 3) transfer new management and genetic technologies to private industrial and non-industrial landowners; and 4) educate a diverse cross-section of the public about the relevance of forests, forest management, and climate change. These efforts will enable our stakeholders to enhance the productivity of southern pine forests, while maintaining social, economic, and ecological sustainability.

  6. Machine Learning Approaches for Predicting Radiation Therapy Outcomes: A Clinician's Perspective.

    2015-12-01

    Radiation oncology has always been deeply rooted in modeling, from the early days of isoeffect curves to the contemporary Quantitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC) initiative. In recent years, medical modeling for both prognostic and therapeutic purposes has exploded thanks to increasing availability of electronic data and genomics. One promising direction that medical modeling is moving toward is adopting the same machine learning methods used by companies such as Google and Facebook to combat disease. Broadly defined, machine learning is a branch of computer science that deals with making predictions from complex data through statistical models. These methods serve to uncover patterns in data and are actively used in areas such as speech recognition, handwriting recognition, face recognition, "spam" filtering (junk email), and targeted advertising. Although multiple radiation oncology research groups have shown the value of applied machine learning (ML), clinical adoption has been slow due to the high barrier to understanding these complex models by clinicians. Here, we present a review of the use of ML to predict radiation therapy outcomes from the clinician's point of view with the hope that it lowers the "barrier to entry" for those without formal training in ML. We begin by describing 7 principles that one should consider when evaluating (or creating) an ML model in radiation oncology. We next introduce 3 popular ML methods--logistic regression (LR), support vector machine (SVM), and artificial neural network (ANN)--and critique 3 seminal papers in the context of these principles. Although current studies are in exploratory stages, the overall methodology has progressively matured, and the field is ready for larger-scale further investigation. PMID:26581149

Materials and methods: The study employed a prospective, randomized, controlled trial design. The 4-month intervention consisted of self-guided HAPA-based workbooks in addition to two telephone calls to assist participants with the program implementation, and was compared to “treatment as usual”. Participants (n=87 completed health measures (diet, body mass index [BMI], waist circumference, blood pressure, blood glucose levels, lipid levels, and diabetes distress and HAPA measures prior to the intervention and again upon completion 4 months later. Results: The overall HAPA model predicted BMI, although only risk awareness and recovery self-efficacy were significant independent contributors. Risk awareness, intentions, and self-efficacy were also independent predictors of health outcomes; however, the HAPA did not predict healthy eating. No significant time × condition interaction effects were found for diet or any HAPA outcome measures. Conclusion: Despite the success of HAPA in predicting health outcomes for those with type 2 diabetes mellitus, the intervention was unsuccessful in changing healthy eating or any of the other measured variables, and alternative low-cost health interventions for those with type 2 diabetes mellitus should be explored.

  8. Central venous infusion port inserted via high versus low jugular venous approaches: Retrospective comparison of outcome and complications

    International Nuclear Information System (INIS)

    Purpose: To retrospectively compare immediate and long-term outcome of central venous infusion port inserted via right high versus low jugular vein approaches. Materials and methods: The study included 163 patients (125 women patients, 38 men patients; age range, 18-79 years; mean age, 53 years); 142 patients underwent port insertion with low jugular vein approach and 21 patients with high jugular vein approach. The causes of high jugular vein puncture were metastatic lymphadenopathy (n = 7), operation scar (n = 6), radiation scar (n = 5), failure of low jugular vein puncture (n = 2), and abnormal course of right subclavian artery (n = 1). Medical records and radiologic studies were reviewed retrospectively to determine and compare the outcome and the occurrence of complication related to port. Results: The procedure-related complications were all minor (n = 14, 8.6%) in both groups; hematoma (n = 4, 2.8% in low jugular puncture group and n = 1, 4.8% in high jugular puncture group, p = 0.6295), air embolism (n = 2, 1.4% in low jugular puncture group and n = 0 in high jugular puncture group, p = 0.5842) and minor bleeding (n = 5, 3.5% in low jugular vein puncture group and n = 2, 9.5% in high jugular vein puncture group, p = 0.2054). The average length of follow-up was 431 days for low jugular vein puncture group and 284 days for high jugular vein puncture group. The difference between two groups was significant (p = 0.0349). The reasons for catheter removal were patients' death (59 in low jugular puncture group and 14 in high jugular puncture group, p = 0.0465), suspected infection (11 in low jugular vein puncture group and 2 in high jugular vein puncture group, p = 0.8242), catheter occlusion (four in low jugular vein puncture group and one in high jugular vein puncture group, p = 0.6583). The catheter tip migrated upward an average of 1.86 cm (range, -0.5 to 5.0 cm) in low jugular vein puncture group and 1.56 cm (range, 0-3.6 cm) in high jugular vein puncture group and there was no significant difference (p = 0.4232). Conclusions: Right high jugular vein approach can be a feasible alternative to right low jugular vein approach.

    2016-02-01

    Little substance use disorder (SUD) treatment research with emerging adults ages 18-25 has been done in community settings, and it is well-known that peers influence emerging adult substance use. The purpose of this study was to develop and test the feasibility of a peer-enhanced behavioral treatment for emerging adults with substance use problems. Emerging adults (n=35) received a peer-enhanced version of the Community Reinforcement Approach (Peer-CRA), in which their peers (n=34) were trained to provide alcohol-specific social support. Both identified clients and peers were interviewed at treatment intake, and again three and six months later. Six month outcomes included days of abstinence adjusted for controlled environment days, social costs due to substance use, and binge drinking days in the past 90days. Treatments were delivered with high fidelity, and a high proportion of participants were retained in treatment and follow-up assessments. Growth curve analyses revealed that emerging adults and their peers significantly increased their days of abstinence and reduced their binge drinking over time. Larger randomized trials should a) test whether peer-enhanced treatments are efficacious relative to treatment as usual, b) investigate whether secondary benefits exist for non-treatment seeking peers supporting another's treatment, and c) examine whether proposed mechanisms of change (i.e., peer support and peer reductions in substance use) account for any differences in outcomes.

    2014-12-01

    Attention-deficit/hyperactivity disorder (ADHD) is a prevalent and chronic mental health condition that often results in substantial impairments throughout life. Although evidence-based pharmacological and psychosocial treatments exist for ADHD, effects of these treatments are acute, do not typically generalize into non-treated settings, rarely sustain over time, and insufficiently affect key areas of functional impairment (i.e., family, social, and academic functioning) and executive functioning. The limitations of current evidence-based treatments may be due to the inability of these treatments to address underlying neurocognitive deficits that are related to the symptoms of ADHD and associated areas of functional impairment. Although efforts have been made to directly target the underlying neurocognitive deficits of ADHD, extant neurocognitive interventions have shown limited efficacy, possibly due to misspecification of training targets and inadequate potency. We argue herein that despite these limitations, next-generation neurocognitive training programs that more precisely and potently target neurocognitive deficits may lead to optimal outcomes when used in combination with specific skill-based psychosocial treatments for ADHD. We discuss the rationale for such a combined treatment approach, prominent examples of this combined treatment approach for other mental health disorders, and potential combined treatment approaches for pediatric ADHD. Finally, we conclude with directions for future research necessary to develop a combined neurocognitive + skill-based treatment for youth with ADHD. PMID:25120200

    This research paper presents the outcomes of Work Package 5 (socio-economical vulnerability assessment and community-based disaster risk reduction) of the MIAVITA (MItigate and Assess risk from Volcanic Impact on Terrain and human Activities) research programme conducted on Fogo Volcano, Cape Verde. The study lasted for almost 3 years (May 2010 to January 2012), of which most of the time was spent in the village of Chã das Caldeiras, situated within the 9 km wide caldera of the volcano inside Fogo Natural Park. The objectives of the programme included assessment of the vulnerability of the community at risk in terms of livelihoods, access to resources, and power relations between the local people and the different public and private institutions. These are important factors that need to be investigated in order to understand the root causes of vulnerability of the local people. This case study shows that the voluntary exposure of people to volcanic threats is linked to daily access to sources of livelihood, especially agriculture and tourism. This is despite the perception of people of the risk to their lives and properties. In order to counter the factors of vulnerability, the study also aimed to identify and enhance local capacities. To achieve such an objective, a participatory three-dimensional mapping (P3DM) activity was conducted to facilitate the dialogue between the local people and the different stakeholders as well as to prepare plans and measures to reduce volcanic risk. The P3DM was a half success considering that it has not yet led to an operational plan which takes into account the local capacities. The main reasons included (1) the non-participatory aspect of the project at the beginning which should have identified priorities for people and let them lead the project to ensure the sustainability of (2) deep conflicts within the community which complicated the focus group discussions around the 3-D map, and the difficulties in involving more marginalised people like women and the youth, and (3) the fact that volcanic risk is not a priority for the people, who are more concerned with daily difficulties due to unsustainable livelihoods, a lack of access to water, land tenure, and the restrictions by the Fogo Natural Park administration and the municipal officials. Still, the study was successful in creating a space for dialogue between the local people and the outside stakeholders such as the Natural Park Administration, the Civil Protection, and the Municipality of Santa Catarina, who have all participated actively during the course of the project.

  12. A conservative approach to pediatric mandibular fracture management: Outcome and advantages

    Full Text Available Pediatric mandibular fractures are rare and their treatment remains controversial. Management is extremely complicated in mixed dentition as it is inherently dynamic and unstable. Treatment options include soft diet, intermaxillary fixation with eyelet wires, arch bars, circummandibular wiring, or stents. Alternative options include open reduction and internal fixation through either an intraoral or extraoral approach. This case report describes and evaluates the conservative technique of acrylic splint in the treatment of pediatric mandible fracture in a 12-year-old female child. The patient with isolated mandibular fracture was treated with acrylic splint and interdental wiring followed by evaluation of clinical and radiographic healing as well as the somatosensory status. Patient demonstrated clinical union to her pre-injury occlusion by three to four weeks. Panoramic finding supported the finding of clinical examination throughout the study. High osteogenic potential of the pediatric mandible allowed conservative management to be successful in this case.

    Traumatic brain injury (TBI) warranting neurosurgical intervention in the pregnant population is a rarity. We describe a case of a 27-year-old woman who at 13 weeks of gestation presented with multiple traumas having been involved in a near fatal road traffic accident. Glasgow Coma Scale was 6\\/15. CT brain showed extensive haemorrhagic contusions, diffuse brain swelling and multiple skull and facial fractures. Decompressive craniectomy was performed to control her intracranial pressure during her management in the intensive care. A viable intrauterine pregnancy was confirmed and progressed as maternal stabilisation and rehabilitation continued. At 35+3 weeks a 2770 g male child was delivered via emergency caesarean section after spontaneous onset of labour. The child had no detectable abnormalities and is clinically well. Eight months post-TBI the patient continues to make gradual improvements but is left with severe cognitive impairment and currently undergoing rehabilitation. A multidisciplinary approach was adopted in the management of this patient.

  15. Cybernetic approach to the problem of prognosis of the radiation injury outcome in animals

    International Nuclear Information System (INIS)

    The cybernetic approach to the problem in question lies in revealing the differences in the quality of control systems of animal physiological functions. For this purpose the ''perturbation'' effect (hypoxic load) is used and with the help of computers the characteristics of transition processes in the systems are analyzed for two classes of animals compared (irradiation survivors and non-survivors). For the irradiation retrieval the forecast error was 9.7 per cent. The experiments were conducted on the white nonlinear mice. Each animal was placed into hermetic chamber and subjected to anoxic hypoxia for 5 min at 10 per cent oxygen content in the inhaled Mixture. Then the mixture was replaced by common air for 2 min and during the subsequent 5 min the aftereffect reaction was recorded after 1.5-2 week examination the animals were gamma irradiated at the dose of 750 R and the dose rate of 355 R/min and the survival was determined by the 30th day

    Full Text Available Abstract Background The CQ Index for the elderly, a quality-of-care questionnaire administered by conducting interviews, is used to assess clients' experiences in Dutch nursing homes and homes for the elderly. This article describes whether inter-interviewer differences influence the perceived quality of healthcare services reported by residents, the size of this interviewer effect and the influence of the interviewer characteristics on CQ Index dimensions for public reporting. Methods Data from 4345 questionnaires was used. Correlations were calculated, reliability analyses were performed, and a multilevel analysis was used to calculate the degree of correlation between two interviewers within one health care institution. Five models were constructed and the Intra Class Correlation (ICC was calculated. Healthcare institutions were given 1-5 stars on every quality dimensions (1 = worst and 5 = best, adjusted for resident and interviewer characteristics. The effect of these characteristics on the assignment of the stars was investigated. Results In a multilevel approach, the ICC showed a significant amount of variance on five quality dimensions. Of the interviewer characteristics, only previous interviewing experience, the reason of interviewing and general knowledge of health care had a significant effect on the quality dimensions. Adjusting for interviewer characteristics did not affect the overall star assignment to the institutions regarding 7 of 12 quality dimensions. For the other five dimensions (Shared decision-making, Meals, Professional competency, Autonomy, and Availability of personnel a minor effect was found. Conclusions We have shown that training, the use of experienced interviewers, written instructions, supervision and educational meetings do not automatically prevent interviewer effects. While the results of this study can be used to improve the quality of services provided by these institutions, several CQ index dimensions should be interpreted with caution for external purposes (accountability and transparency.

    Purpose To determine the efficacy and safety of repeated intravitreal and subconjunctival administrations of sirolimus in patients with noninfectious uveitis at 1 year in the Sirolimus as a Therapeutic Approach UVEitis (SAVE) Study. Methods Open-label, prospective, and randomized interventional clinical trial in which 30 patients with noninfectious intermediate, posterior, or panuveitis were randomized 1:1 to receive sirolimus 352-?g intravitreal or 1320-?g subconjunctival. Sirolimus was administered at days 0, 60, and 120. At month 6, all subjects were allowed to receive sirolimus at intervals greater than or equal to 2 months and until month 12. Changes in vitreous haze (VH), visual acuity (VA), and retinal thickness at month 12 were compared with baseline. Results Of patients with active uveitis at baseline (n = 20), 70% showed greater than or equal to 2 steps reduction of VH at month 12 (P < 0.05), 88% (n = 7) of patients with inactive uveitis at baseline showed either no change or reduction of VH to no haze, 36% (n = 10) of all patients (n = 28) gained greater than or equal to one line of VA, 21% (n = 6) lost greater than or equal to 1 line, and 43% (n = 12) showed no change. At the end of 1 year, no statistical differences in efficacy were found between intravitreal and subconjunctival groups. No serious adverse events were determined to be secondary to sirolimus. Conclusions Repeated subconjunctival/intravitreal injections of sirolimus appear to be tolerated by patients with noninfectious uveitis over 12 months. Results from the index study suggest that sirolimus may provide benefits to patients with uveitis. Both intravitreal and subconjunctival routes demonstrate similar bioactivity/efficacy. The intravitreal route, however, was better tolerated. Translational Relevance The SAVE Study illustrates for the first time the application of local formulations of sirolimus in non-infectious intermediate, posterior, and pan-uveitis. Subconjunctival/Intravitreal sirolimus may help to control inflammation while offering better tolerability/safety profiles than systemic therapies, including immunosuppressants and corticosteroids.

  20. Three-dimensional time-dependent Hartree-Fock approach for arbitrarily oriented molecular hydrogen in strong electromagnetic fields

    International Nuclear Information System (INIS)

    We present a theoretical framework for the electronic dynamics of arbitrarily oriented molecular hydrogen in strong and short electromagnetic fields. The ground state of H2 is obtained by propagating the time-dependent Schroedinger equation in imaginary time by assuming the Hartree-Fock ansatz for the interaction between the electrons. The interaction of H2 with the radiation field is considered in the single-active-electron approximation, with the continuum electron subject to Hartree-Fock radial potentials. We propagate the wave function by a split-operator scheme projected on a spherical harmonics basis. Alignment-dependent yields and angular distributions for one- and two-photon ionization induced by an external femtosecond light source are presented and compared with available theoretical results

  1. Linking the actors and policies throughout the disaster management cycle by "Agreement on Objectives" – a new output-oriented management approach

    Full Text Available Current management of disaster risks is often fragmented due to a lack of coordination between involved actors, i.e. civil protection and spatial planning – a phenomenon which is known as the "problem of interplay". This paper presents an output-oriented risk management approach ("parametric governance". Here, the modality of the achievement of objectives remains in the hands of the given addressees. This implies a shift from a top-down to a more collaborative, process-oriented form of decision-making. The approach has been successfully applied in two hazard cases and three administrative contexts: (a the City of Dortmund (Germany facing flash floods, (b East Attica region (Greece facing forest fires, and (c Lazio Region (Italy also facing forest fires. As proved by the applications of the concept, a dialogue among experts, stakeholders, and decision-makers is indispensable in order to guarantee inclusion of all diverse and competing values, opinions, and claims. Moreover, a structured communication path is needed to meet the requirements of a risk governance process. Finally, a win-win-situation among the involved actors has to be created to reach an agreement on common goals and actions to achieve them in due time.

    In many clinical settings, there is a high comorbidity between substance use disorders, psychiatric disorders, and traumatic stress. Novel therapies are needed to address these co-occurring issues efficiently. The aim of the present study was to conduct a pragmatic randomized controlled trial comparing Mindfulness-Oriented Recovery Enhancement (MORE) to group Cognitive-Behavioral Therapy (CBT) and treatment-as-usual (TAU) for previously homeless men residing in a therapeutic community. Men with co-occurring substance use and psychiatric disorders, as well as extensive trauma histories, were randomly assigned to 10 weeks of group treatment with MORE (n = 64), CBT (n = 64), or TAU (n = 52). Study findings indicated that from pre-to post-treatment MORE was associated with modest yet significantly greater improvements in substance craving, post-traumatic stress, and negative affect than CBT, and greater improvements in post-traumatic stress and positive affect than TAU. A significant indirect effect of MORE on decreasing craving and post-traumatic stress by increasing dispositional mindfulness was observed, suggesting that MORE may target these issues via enhancing mindful awareness in everyday life. This pragmatic trial represents the first head-to-head comparison of MORE against an empirically-supported treatment for co-occurring disorders. Results suggest that MORE, as an integrative therapy designed to bolster self-regulatory capacity, may hold promise as a treatment for intersecting clinical conditions. PMID:26701171

    There is growing interest in operationalising the capability approach to measure quality of life. This paper reports the results of a research project undertaken in 2007 that sought to reduce and refine a longer survey in order to provide a summary measure of wellbeing and capability in the realm of public health. The reduction and refinement of the questionnaire took place across a number of stages, using both qualitative (five focus group discussions and 17 in-depth interviews) and quantitative (secondary data analysis, N = 1048 and primary data collection using postal surveys and interviews, N = 45) approaches. The questionnaire was reduced from its original 60+ questions to 24 questions (including demographic questions). Each of Nussbaum's ten Central Human Capabilities are measured using one (or more) of the 18 specific capability items which are included in the questionnaire (referred to as the OCAP-18). Analysis of the questionnaire responses (N = 198) found that respondents differed with respect to the levels of capabilities they reported, and that these capabilities appear to be sensitive to one's gender, age, income and deprivation decile. An index of capability, estimated by assuming equal weight for each capability question, found that the average level of capability amongst respondents was 12.44 (range 3-17.75). This index was found to be highly correlated with a measure of health (EQ-5D) and wellbeing (global QoL), although some differences were apparent. This project operationalised the capability approach to produce an instrument to measure the effectiveness (and cost effectiveness) of public health interventions; the resulting OCAP-18 appears to be responsive and measure something supplementary to health and wellbeing, thus offers a promising addition to the current suite of outcome measures that are available.

    For lesbian, gay, bisexual, and transgender (LGBT) youth, coming out (i.e., disclosure of LGBT identity to others) can be a key developmental milestone, one that is associated with better psychological well-being. However, this greater visibility may come with increased risk of peer victimization. Being out, therefore, may reflect resilience and may unfold differently depending on ecological context as some spaces may be more or less supportive of LGBT youth than others. This article explores a model of risk and resilience for outness among LGBT youth, including whether it varies by community context. We tested our hypothesized model with a national dataset of 7,816 LGBT secondary school students using multi-group structural equation modeling. Consistent with our hypotheses, outness was related to higher victimization but also to higher self-esteem and lower depression. Greater victimization was related to negative academic outcomes directly and indirectly via diminished well-being. The increases in victimization associated with outness were larger for rural youth, and benefits to well-being partly compensated for their lower well-being overall. This article suggests that being out reflects resilience in the face of higher risk of victimization, in addition to promoting well-being in other ways. Nonetheless, contextual factors influence how this model operates among LGBT youth. PMID:24691967

    We present a new numerical method for reconstruction of instantaneous density volume from 3D background-oriented schlieren (3DBOS) measurements, with a validation on a dedicated flexible experimental BOS bench. In contrast to previous works, we use a direct formulation where density is estimated from measured deviation fields without the intermediate step of density gradient reconstruction. Regularization techniques are implemented to deal with the ill-posed problem encountered. The resulting high-dimensional optimization is conducted by conjugate gradient techniques. A parallel algorithm, implemented on graphics processing unit, helps to speed up the calculation. The resulting software is validated on synthetic BOS images of a 3D density field issued from a numerical simulation. Then, we describe a dedicated 3DBOS experimental facility which has been built to study various BOS settings and to assess the performance of the proposed numerical reconstruction process. Results on various datasets illustrate the potential of the method for flow characterization and measurement in real-world conditions.

    Full Text Available The aim of this paper is to further the study of the factors that influence the international competitive position of international new ventures and, consequently, their international performance. Specifically, we analyze the role of entrepreneurial and market orientations in the international competitive position of such firms. Data were collected at Spanish and Belgian international new ventures. The structural equations model approach was used to test our hypotheses. Both the Spanish and the Belgian sample revealed a positive and significant relationship between entrepreneurial orientation and market orientation. Furthermore, both orientations have a positive and significant effect on the international competitive position of such firms. Finally, any firm’s international competitive position is positively and significantly related to its international performance. The study therefore appears to indicate that, when it comes to international new ventures, the conjunction of these two orientations is a key factor to attaining a superior competitive position and a positive performance in international markets.

  10. A Multimodal Approach Including Craniospinal Irradiation Improves the Treatment Outcome of High-risk Intracranial Nongerminomatous Germ Cell Tumors

    International Nuclear Information System (INIS)

    Purpose: To evaluate whether a multimodal approach including craniospinal irradiation (CSI) improves treatment outcome in nongerminomatous germ cell tumor (NGGCT) patients. Methods and Materials: We reviewed the records of 32 patients with NGGCTs. Fourteen patients belonged to the intermediate prognosis group (immature teratoma, teratoma with malignant transformation, and mixed tumors mainly composed of germinoma or teratoma), and 18 patients belonged to the poor prognosis group (other highly malignant tumors). Patients with pure germinoma or mature teratoma were excluded from this study. Nineteen patients were treated with a combination of surgery, chemotherapy, and radiotherapy (RT); 9 patients received chemotherapy plus RT; 3 patients received surgery plus RT; and 1 patient received RT alone. Twenty-seven patients received CSI with a median of 36 Gy (range, 20–41 Gy) plus focal boost of 18–30.6 Gy, and 5 patients received whole-brain RT (WBRT) (20–36 Gy) or focal RT (50.4–54 Gy). The rate of total and subtotal resection was 71.9%. The median follow-up for surviving patients was 121 months. Results: Treatment failed in 7 patients. Three of the 5 patients who received focal RT or WBRT had local failure. Four cerebrospinal fluid (CSF) failures occurred after CSI. No failure occurred in the intermediate prognosis group. Ten-year recurrence-free survival (RFS) and overall survival (OS) for all patients were 77.6% and 74.6%, respectively. Ten-year RFS for the intermediate and poor prognosis groups were 100% and 61.1%, respectively (p = 0.012). OS for the two groups were 85.1% and 66.7%, respectively (p = 0.215). Tumor histology and CSI were significant prognostic factors for RFS, and CSI was significantly associated with OS. Conclusions: A multimodal approach was effective for treating NGGCTs. CSI should be considered for patients with poor prognostic histology.

    Full Text Available Roy Fox1, Tara Sampalli1, Jonathan Fox11Nova Scotia Environmental Health Centre, Fall River, NS, CanadaAbstract: The Nova Scotia Environmental Health Centre is a treatment facility for individuals with chronic environmental conditions such as multiple chemical sensitivity, chronic fatigue syndrome, fibromyalgia, chronic respiratory conditions and in some cases chronic pain. The premise of care is to provide a patient-centred multidisciplinary care approach leading to self-management strategies. In order to measure the outcome of the treatment in these complex problems, with overlapping diagnoses, symptoms in many body systems and suspected environmental triggers, a detailed symptoms questionnaire was developed specifically for this patient population and validated. Results from a pilot study in which an abbreviated symptoms questionnaire based on the top reported symptoms captured in previous research was used to measure the efficacy of a multidisciplinary care approach in individuals with multiple chemical sensitivity are presented in this paper. The purpose of this study was to examine the extent, type and patterns of changes over time in the top reported symptoms with treatment measured using the abbreviated symptoms questionnaire. A total of 183 active and 109 discharged patients participated in the study where the health status was measured at different time periods of follow up since the commencement of treatment at the Centre. The findings from this study were successful in generating an initial picture of the nature and type of changes in these symptoms. For instance, symptoms such as difficulty concentrating, sinus conditions and tiredness showed early improvement, within the first 6 months of being in treatment, while others, such as fatigue, hoarseness or loss of voice, took longer while others showed inconsistent changes warranting further enquiry. A controlled longitudinal study is planned to confirm the findings of the pilot study.Keywords: multiple chemical sensitivity, multidisciplinary, chronic conditions

  13. Development of the negative gravity anomaly of the 85°E Ridge, northeastern Indian Ocean – A process oriented modelling approach

    The 85°E Ridge extends from the Mahanadi Basin, off northeastern margin of India to the Afanasy Nikitin Seamount in the Central Indian Basin. The ridge is associated with two contrasting gravity anomalies: negative anomaly over the north part (up to 5°N latitude), where the ridge structure is buried under thick Bengal Fan sediments and positive anomaly over the south part, where the structure is intermittently exposed above the seafloor. Ship-borne gravity and seismic reflection data are modelled using process oriented method and this suggest that the 85°E Ridge was emplaced on approximately 10–15 km thick elastic plate (Te) and in an off-ridge tectonic setting. We simulated gravity anomalies for different crust-sediment structural configurations of the ridge that were existing at three geological ages, such as Late Cretaceous, Early Miocene and Present. The study shows that the gravity anomaly of the ridge in the north has changed through time from its inception to present. During the Late Cretaceous the ridge was associated with a significant positive anomaly with a compensation generated by a broad flexure of the Moho boundary. By Early Miocene the ridge was approximately covered by the postcollision sediments and led to alteration of the initial gravity anomaly to a small positive anomaly. At present, the ridge is buried by approximately 3 km thick Bengal Fan sediments on its crestal region and about 8 km thick pre- and post-collision sediments on the flanks. This geological setting had changed physical properties of the sediments and led to alter the minor positive gravity anomaly of Early Miocene to the distinct negative gravity anomaly.

    This paper addresses the impact of innovative developments in Russian policy-making discourse during the Putin presidency on the transformation of conflict issues in EU-Russian relations. The increasing recourse of Russian policy-makers in the border regions to the so-called ‘projectoriented approach’, which has an affinity to the modality of policy-making espoused by the EU programmes in Russia, has important consequences for conflictual dispositions in EU-Russian trans-border relations.

  17. Transcriptome walking: a laboratory-oriented GUI-based approach to mRNA identification from deep-sequenced data

    Directory of Open Access Journals (Sweden)

    French Andrew S

    2012-12-01

    Full Text Available Abstract Background Deep sequencing technology provides efficient and economical production of large numbers of randomly positioned, relatively short, estimates of base identities in DNA molecules. Application of this technology to mRNA samples allows rapid examination of the molecular genetic environment in individual cells or tissues, the transcriptome. However, assembly of such short sequences into complete mRNA creates a challenge that limits the usefulness of the technology, particularly when no, or limited, genomic data is available. Several approaches to this problem have been developed, but there is still no general method to rapidly obtain an mRNA sequence from deep sequence data when a specific molecule, or family of molecules, are of interest. A frequent requirement is to identify specific mRNA molecules from tissues that are being investigated by methods such as electrophysiology, immunocytology and pharmacology. To be widely useful, any approach must be relatively simple to use in the laboratory by operators without extensive statistical or bioinformatics knowledge, and with readily available hardware. Findings An approach was developed that allows de novo assembly of individual mRNA sequences in two linked stages: sequence discovery and sequence completion. Both stages rely on computer assisted, Graphical User Interface (GUI-guided, user interaction with the data, but proceed relatively efficiently once discovery is complete. The method grows a discovered sequence by repeated passes through the complete raw data in a series of steps, and is hence termed ‘transcriptome walking’. All of the operations required for transcriptome analysis are combined in one program that presents a relatively simple user interface and runs on a standard desktop, or laptop computer, but takes advantage of multi-core processors, when available. Complete mRNA sequence identifications usually require less than 24 hours. This approach has already identified previously unknown mRNA sequences in two animal species that currently lack any significant genome or transcriptome data. Conclusions As deep sequencing data becomes more widely available, accessible methods for extracting useful sequence information in the biological or medical laboratory will be of increasing importance. The approach described here does not rely on detailed knowledge of bioinformatic algorithms, and allows users with basic knowledge of molecular biology and standard laboratory computing equipment, but limited software or bioinformatics experience, to extract complete gene sequences from deep-sequencing data.

    1995-01-01

    Estimates of staff orientation costs can range from $20,000-50,000 per person. The Director of Finance and the Director of Nursing Education and Research developed a system to track the orientation process to determine the actual costs. Head nurses and educators approached the orientation process differently; therefore, there was no consistency as to the time allotted for orientation. Although competency-based orientation tools were used for all new orientees, the average amount of time for new orientees to become productive ranged from 3-9 months. By creating the orientation matrix, a unique pay class (code 50) was assigned for all new orientees, and a computer program was developed to track costs. The overtime hours for orientees dropped to 159 from 941, resulting in an 83% reduction in overtime hours. The matrix ensured a more cost effective approach to orientation. PMID:7562073

  20. Numerically oriented static response approach based on state-specific multi-reference coupled electron-pair approximation (SS-MRCEPA) like methods

    International Nuclear Information System (INIS)

    In this paper, we have exploited the recently developed state-specific multi-reference coupled electron-pair approximation (SS-MRCEPA) like methods for computing the electrostatic response properties. The SS-MRCEPA methods are formulated on complete active space reference functions and the required energies are computed via the diagonalization of an effective operator within this space. The SS-MRCEPA theories are size-consistent and size-extensive. They are very efficient for treating quasidegeneracy of varying extent and for bypassing the intruder problem. The efficacy of the methods is illustrated via the computation of the static dipole moment and polarizability of the ground state and the corresponding first excited state of the trapezoidal H4 model (H4) as well as the lowest two singlet states of the CH2 system using perturbed orbitals generated via the finite-field strategy, a numerically oriented static response approach

  1. Application of the microcrack growth law-oriented approach for assessing anisotropy in the low-cycle fatigue strength of thick forged A 533 B steel plates

    International Nuclear Information System (INIS)

    The microcrack growth law-oriented approach developed in a previous paper is applied to examine the fatigue strength and mechanism of 200 mm and 100 mm thick forged steel plates. Low-cycle fatigue tests are conducted on specimens sliced in the transverse (T) and thickness (S) directions of the plates. Through continual observation of the fatigue process, the effect of elongated inclusions on microcrack initiation and propagation behaviors is elucidated. The fatigue life is shorter in the S than in the T direction. The fatigue lives in both directions are evaluated on the basis of the microcrack propagation law. The elongated inclusions hardly affect the fatigue process in the T direction, while they show a strong influence in the S direction. The fatigue process is dominated by a monotonous growth of a leading crack in the T direction. On the contrary, the leading crack growth in the S direction is governed by a joining of subcracks.

    We estimated inflow rates of perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) to Tokyo Bay, Japan, between February 2004 and February 2011 by a receptor-oriented approach based on quarterly samplings of the bay water. Temporal trends in these inflow rates are an important basis for evaluating changes in PFOS and PFOA emissions in the Tokyo Bay catchment basin. A mixing model estimated the average concentrations of these compounds in the freshwater inflow to the bay, which were then multiplied by estimated freshwater inflow rates to obtain the inflow rates of these compounds. The receptor-oriented approach enabled us to comprehensively cover inflow to the bay, including inflow via direct discharge to the bay. On a logarithmic basis, the rate of inflow for PFOS decreased gradually, particularly after 2006, whereas that for PFOA exhibited a marked stepwise decrease from 2006 to 2007. The rate of inflow for PFOS decreased from 730kg/y during 2004-2006 to 160kg/y in 2010, whereas that for PFOA decreased from 2000kg/y during 2004-2006 to 290kg/y in 2010. These reductions probably reflected reductions in the use and emission of these compounds and their precursors in the Tokyo Bay catchment basin. Our estimated per-person inflow rates (i.e., inflow rates divided by the estimated population in the basin) for PFOS were generally comparable to previously reported per-person waterborne emission rates in Japan and other countries, whereas those for PFOA were generally higher than previously reported per-person waterborne emission rates. A comparison with previous estimates of household emission rates of these compounds suggested that our inflow estimates included a considerable contribution from point industrial sources.

    Here we describe several useful strategies to a variety of unusual ?-amino acid derivatives and peptides based on "building block" approach. These building blocks are suitable for modification at an amino acid as well as at a peptide level. Moreover, these methods have embedded several points for diversification and are capable of producing a library of modified amino acids and peptides. We have employed highly atom-economic processes such as the Diels-Alder reaction, [2 + 2 + 2] cycloaddition, Suzuki-Miyaura cross-coupling, and olefin metathesis as key steps to assemble various unnatural amino acid derivatives and peptides. In some instances, we have used rongalite to generate Diels-Alder precursors. PMID:24219241

  5. Coupling low and high trophic levels models: Towards a pathways-orientated approach for end-to-end models

    Science.gov (United States)

    2010-01-01

    Existing models of marine ecosystems address specific issues related to the bottom-up forcing of production or to the top-down effects of fishing on a limited range of the trophic spectrum. Very few existing models explicitly incorporate the dynamics from one end of the ecosystem to the other and thus allowing the exploration of interplay between exploitation and climate effects. The shift to an ecosystem approach to fisheries and concerns about the ecological effects of climate change require the assemblage of knowledge assembled from the respective marine disciplines with the view to build end-to-end models of marine ecosystems. Here, with a focus on plankton and fish models, we present some issues and recommendations for the integration of models between trophic levels (vertical integration) and within functional groups (horizontal integration within trophic levels). At present, vertical coupling of plankton and fish models is mainly realized through predation processes, generally represented as a functional response. In the absence of empirical evidence and quantification, the choice of the functional response term is often made by default, and is reduced to a parameterization problem. A strategy is proposed to overcome this arbitrary choice. In addition to the vertical coupling of trophic models, the structure of end-to-end models incorporates biodiversity via horizontal integration of trophic levels. For guiding the selection of key components to be included in end-to-end models, the idea that marine food webs are structured as alternative trophic pathways is highlighted and related to observed dynamics. We suggest that an important early step in model development is the identification of major trophic pathways and bottlenecks in an ecosystem using a historical perspective.

    By combining experimental and theoretical approaches, the electronic structure, molecular orientation, charge transfer dynamics and solar cell performance in donor/acceptor copolymer poly[2,7-(9,9-bis(2-ethylhexyl)-dibenzosilole)-alt-4,7-bis(thiophen-2-yl) benzo-2,1,3-thiadiazole] (PSiF-DBT) films and blended with 6,6.-phenyl-C 61-butyric acid methyl ester (PSiF-DBT:PCBM) were investigated. Good agreement between experimental and theoretical PSiF-DBT UV-Vis absorption spectrum is observed and the main molecular orbitals contributing to the spectrum were determined using DFT single point calculations. Non-coplanar configuration was determined by geometric optimization calculation in isolated PSiF-DBT pentamer and corroborated by angular variation of the sulphur 1s near-edge X-ray absorption fine structure (NEXAFS) spectra. Edge-on and plane-on molecular orientations were obtained for thiophene and benzothiadiazole units, respectively. A power conversion efficiency up to 1.58%, open circuit voltage of 0.51 V, short circuit current of 8.71 mA/cm{sup 2} and a fill factor of 35% was obtained using blended PSiF-DBT:PCBM as active layer in a bulk heterojunction solar cell. Ultrafast electron dynamics in the low-femtosecond regime was evaluated by resonant Auger spectroscopy using the core-hole clock methodology around sulphur 1s absorption edge. Electron delocalization times for PSiF-DBT and PSiF-DBT:PCBM polymeric films were derived for selected excitation energies corresponding to the main transitions in the sulphur 1s NEXAFS spectra. The mixture of PSiF-DBT with PCBM improves the charge transfer process involving the ?* molecular orbital of the thiophene units.

    Full Text Available Abstract Background We have reported promising outcomes using a staged approach, in which bortezomib/thalidomide/dexamethasone was used only in 14 patients with suboptimal response to VAD (vincristine/adriamycin/dexamethasone before autologous stem cell transplantation (ASCT. Here we compared the outcomes of the staged approach with frontline PAD (bortezomib/doxorubicin/dexamethasone or VTD (bortezomib/thalidomide/dexamethasone induction, and analysed prognostic factors for outcome. Patients and methods Ninety-one transplant-eligible Chinese patients received three induction regimens prior to ASCT [staged approach (N?=?25, PAD (N?=?31, VTD (N?=?35]. and received thalidomide maintenance for 2?years post-ASCT. Results 43 (47.3% patients had International Staging System (ISS III disease. By an intention-to-treat analysis, the overall CR/nCR rate were 37.4% post-induction, and 62.6% post-ASCT. Five-year overall (OS and event-free (EFS survivals were 66% and 45.1%. There was no difference of the post-induction CR/nCR rate, EFS or OS between patients induced by these three regimens. Moreover, ISS III disease did not affect CR/nCR rates. Multivariate analysis showed that ISS and post-ASCT CR/nCR impacted OS while ISS and post-induction CR/nCR impacted EFS. Conclusions These three induction regimens produced comparable and favorable outcomes in myeloma. The unfavorable outcome of ISS stage III persisted despite upfront/early use of bortezomib. CR/nCR predicted favorable survivals.

    Changes in the methods that individual facilities follow to collect and store data related to hospital-acquired pressure ulcer (HAPU) occurrences are essential for improving patient outcomes and advancing our understanding the science behind this clinically relevant issue. Using an established electronic health record system at a large, urban, tertiary-care academic medical center, we investigated the process required for taking raw data of HAPU outcomes and submitting these data to a normalization process. We extracted data from 1.5 million patient shifts and filtered observations to those with a Braden score and linked tables in the electronic health record, including (1) Braden scale scores, (2) laboratory outcomes data, (3) surgical time, (4) provider orders, (5) medications, and (6) discharge diagnoses. Braden scores are important measures specific to HAPUs since these scores clarify the daily risk of a hospitalized patient for developing a pressure ulcer. The other more common measures that may be associated with HAPU outcomes are important to organize in a single data frame with Braden scores according to each patient. Primary keys were assigned to each table, and the data were processed through 3 normalization steps and 1 denormalization step. These processes created 8 tables that can be stored efficiently in a clinical database of HAPU outcomes. As hospitals focus on organizing data for review of HAPUs and other types of hospital-acquired conditions, the normalization process we describe in this article offers directions for collaboration between providers and informatics teams using a common language and structure.

    Learning outcomes are typically developed using standard group-based consensus methods. Two main constraints with standard techniques such as the Delphi method or expert working group processes are: (1) the ability to generate a comprehensive set of outcomes and (2) the capacity to reach agreement on them. We describe the first application of Group Concept Mapping (GCM) to the development of learning outcomes for an interdisciplinary module in medicine and engineering. The biomedical design module facilitates undergraduate participation in clinician-mentored team-based projects that prepare students for a multidisciplinary work environment. GCM attempts to mitigate the weaknesses of other consensus methods by excluding pre-determined classification schemes and inter-coder discussion, and by requiring just one round of data structuring. Academic members from medicine and engineering schools at three EU higher education institutions participated in this study. Data analysis, which included multidimensional scaling and hierarchical cluster analysis, identified two main categories of outcomes: technical skills (new advancement in design process with special attention to users, commercialization and standardization) and transversal skills such as working effectively in teams and creative problem solving. The study emphasizes the need to address the highest order of learning taxonomy (analysis, synthesis, problem solving, creativity) when defining learning outcomes. PMID:24323801

  17. Technology Education Using a Novel Approach in e-Learning-Towards Optimizing the Quality of Learning Outcomes

    Science.gov (United States)

    Malkawi, M. I.; Hawarey, M. M.

    2012-04-01

    Ever since the advent of the new era in presenting taught material in Electronic Form, international bodies, academic institutions, public sectors, as well as specialized entities in the private sector, globally, have all persevered to exploit the power of Distance Learning and e-Learning to disseminate the knowledge in Science and Art using the ubiquitous World Wide Web and its supporting Internet and Internetworking. Many Science & Education-sponsoring bodies, like UNESCO, the European Community, and the World Bank have been keen at funding multinational Distance Learning projects, many of which were directed at an educated audience in certain technical areas. Many countries around the Middle East have found a number of interested European partners to launch funding requests, and were generally successful in their solicitation efforts for the needed funds from these funding bodies. Albeit their intricacies in generating a wealth of knowledge in electronic form, many of the e-Learning schemas developed thus far, have only pursued their goals in the most conventional of ways; In essence, there had been little innovation introduced to gain anything, if any, above traditional classroom lecturing, other than, of course, the gained advantage of the simultaneous online testing and evaluation of the learned material by the examinees. In a sincere effort to change the way in which people look at the merits of e-Learning, and seek the most out of it, we shall propose a novel approach aimed at optimizing the learning outcomes of presented materials. In this paper we propose what shall henceforth be called as Iterative e-Learning. In Iterative e-Learning, as the name implies, a student uses some form of electronic media to access course material in a specific subject. At the end of each phase (Section, Chapter, Session, etc.) on a specific topic, the student is assessed online of how much he/she would have achieved before he/she would move on. If the student fails, due to some delinquency on a particular topic, the online process of e-Learning would take the student at some more detailed and deeper level on the subject matter where he/she had failed; once the student bridges the gap, to this end, then the ongoing e-Learning process would carry him/her further up the next level of the subject matter he/she is pursuing. This process is carried on at all levels of learning: section, chapter, and course level. A student may not progress to the next course level before he/she would pass the entire course at 80% or more. If in the process of repeating some section, chapter, or a whole course, then the student shall be required to score a higher percentage than the mere 80% he was required to attain the first time around; say 5% more per iteration he/she makes. Here, students going through Iterative e-Learning shall be allowed to move on to the next level of learning sooner than others if the time that takes them to learn a particular topic is shorter than would normally require an average student to expend, provided, of course, they make it through all the required assessment phases. Unlike the traditional ways of classroom or online lecturing, a student going through Iterative e-Learning is expected to achieve a quality of learning never before achieved via standard pedagogical methodologies. With Iterative e-Learning, it is expected that poorly accredited academic institutions will be able, for the first time, to produce the quality of graduates who are more capable of competing for highly paying jobs globally, and to be of the quality of contributing in more industry-supported economies.

    2011-01-01

    Full Text Available Object-oriented design is a process of identifying relevant objects, factoring them into classes, organizing hierarchically, and establishing dynamic collaborations among the objects. It is a difficult process especially for novice designers. In order to guide the novices, software engineers used some hints, guidelines and tips to communicate design experience from the expert. Design heuristic is common solution to design problems that developers encounter during software development. Heuristic is defined as the use of general knowledge gained by experience. Design heuristics are design experience from object-oriented developers. It is small and simpledesign expertise. This knowledge from the experienced designers is used to guide the novices. The purpose of this paper is to document design heuristics of object-oriented approach from literature study.

    Full Text Available With the rapid increase in the technology internet plays a major role in the society with the existence of the cloud based scenario. Where it is very much useful in the technology based on information related to the software oriented approach. It is mainly concerned about the utilities of the system which is the primary goal. It play a key role in the transmission of the data with a high definition oriented security based analysis respectively. Therefore whenever the user in the form of the company based software got the requirement of the cloud oriented scenario then he demands the service provider regarding the particular requirement and buys for a rent or a leased scenario and meets the necessary requirement of the company. When ever in this real time environment an investor used to invest a lot of amount for the purpose of infrastructure with high storage and rapid speed. For this reason there is a cost effective phenomena takes place. But suddenly there is an great improvement in the system that itself provides the resources with high quality and storage with security oriented scenario that is on the basis of lease or rent. Therefore the total amount is got remained as it is whatever has to be invested on the resource allocation. Therefore user may start his work with less investment. Now a days it has become very popular and essential tool for the purpose of any advanced oriented research respectively.

  16. A simplified approach for evaluating multiple test outcomes and multiple disease states in relation to the exercise thallium-201 stress test in suspected coronary artery disease

    International Nuclear Information System (INIS)

    This study describes a simplified approach for the interpretation of electrocardiographic and thallium-201 imaging data derived from the same patient during exercise. The 383 patients in this study had also undergone selective coronary arteriography within 3 months of the exercise test. This matrix approach allows for multiple test outcomes (both tests positive, both negative, 1 test positive and 1 negative) and multiple disease states (no coronary artery disease vs 1-vessel vs multivessel coronary artery disease). Because this approach analyzes the results of 2 test outcomes simultaneously rather than serially, it also negates the lack of test independence, if such an effect is present. It is also demonstrated that ST-segment depression on the electrocardiogram and defects on initial thallium-201 images provide conditionally independent information regarding the presence of coronary artery disease in patients without prior myocardial infarction. In contrast, ST-segment depression on the electrocardiogram and redistribution on the delayed thallium-201 images may not provide totally independent information regarding the presence of exercise-induced ischemia in patients with or without myocardial infarction

    Full Text Available Traditional teaching methods used in medical education couldn't meet the need for keeping pace with up to date information. Present study has conducted in order to compare the effect of lecture and e-learning methods on nursing students' learning outcomes in the context of Iran. A cross-over design was applied. Study sample was consisted of 32 students which were in third semester of nursing bachelor program and were passing Maternal Child nursing course. The first part of the course was taught using lecture method during first four weeks; an e-learning method was the technique used to educate the remained part of the course during the second four weeks. Students' learning outcomes in each method, opinion toward and participation with both educational methods was assessed. No significant difference was found between students exam scores in both methods. Considering students' opinion toward educational methods, no significant difference was found between two methods in general but students reported better "capability" and "independency" in e-learning method while lecture was obtained higher scores in "effectiveness on learning" and "motivation" characteristics. E-learning can be used in teaching some nursing courses. It is recommended to use e-learning method with appropriate interactive strategies and attractive virtual environments to motivate students

  20. Self-management interventions in patients with long-term conditions: a structured review of approaches to reporting inclusion, assessment, and outcomes in multimorbidity

    Directory of Open Access Journals (Sweden)

    Cassandra Kenning

    2014-08-01

    Full Text Available Background: Multimorbidity has many potential implications for healthcare delivery, but a particularly important impact concerns the validity of trial evidence underpinning clinical guidelines for individual conditions. Objective: To review how authors of published trials of self-management interventions reported inclusion criteria, sample descriptions, and consideration of the impact of multimorbidity on trial outcomes. Methods: We restricted our analysis to a small number of exemplar long-term conditions: type 2 diabetes mellitus, coronary heart disease, and chronic obstructive pulmonary disease. We focussed our search on published Cochrane reviews. Data were extracted from the trials on inclusion/exclusion, sample description, and impact on outcomes. Results: Eleven reviews consisting of 164 unique trials were identified. Sixty percent of trials reported excluding patients with forms of multimorbidity. Reasons for exclusion were poorly described or defined. Reporting of multimorbidity within the trials was poor, with only 35% of trials reporting on multimorbidity in their patient samples. Secondary analyses, exploring the impact of multimorbidity, were very rare. Conclusions: The importance of multimorbidity in trials is only going to become more important over time, but trials often exclude patients with multimorbidity, and reporting of multimorbidity in trials including such patients is generally poor. This limits judgements about the external validity of the results for clinical populations. A consistent approach to the conduct and reporting of secondary analyses of the effects of multimorbidity on outcomes, using current best-practice guidance, could lead to a rapid development of the evidence base.

  3. Oriental Africa

    Hester, du Plessis.

    2008-01-01

    Full Text Available Arab culture and the religion of Islam permeated the traditions and customs of the African sub-Sahara for centuries. When the early colonizers from Europe arrived in Africa they encountered these influences and spontaneously perceived the African cultures to be ideologically hybridized and more comp [...] atible with Islam than with the ideologies of the west. This difference progressively endorsed a perception of Africa and the east being "exotic" and was as such depicted in early paintings and writings. This depiction contributed to a cultural misunderstanding of Africa and facilitated colonialism. This article briefly explores some of the facets of these early texts and paintings. In the first place the scripts by early Muslim scholars, who critically analyzed early western perceptions, were discussed against the textual interpretation of east-west perceptions such as the construction of "the other". Secondly, the travel writers and painters between 1860 and 1 930, who created a visual embodiment of the exotic, were discussed against the politics behind the French Realist movement that developed in France during that same period. This included the construction of a perception of exoticness as represented by literature descriptions and visual art depictions of the women of the Orient. These perceptions rendered Africa as oriental with African subjects depicted as "exotic others".

  6. A Combined Monitoring and Modelling Approach to Maximise Environmental, Social and Economic Outcomes from Agri-environment Subsidies at a National Scale

    2014-12-01

    Planning, delivery and monitoring of integrated environmental, social and economic outcomes from agri-environmental payments to land owners has rarely been attempted at a national scale. Wales has launched one of the most ambitious projects ever within the EU to frame both delivery of payments and ongoing integrated assessment of outcomes within an ecosystem framework. Payment and evaluation activities are running simultaneously, which when combined with scenario analysis from a suite of biophysical and landscape quality models, allows for adaptive management as the scheme progresses. Social and economic benefits and constraints to uptake of scheme measures and desired outcomes are embedded within the project to ensure benefits to the wider population are realised. Initial modelling results in the first year of the monitoring and evaluation programme quantified potential benefits from a range of management options offered under the subsidy scheme. At a national scale these ranged from: 1 to 9% improvement in flood mitigation; 5 to 10% reduction in greenhouse gas emissions; increased accessible land for 'generic' broadleaf focal species by 3 to 12%, increased national carbon storage by ca. 0.4%, and reduced eroded soil and phosphorus delivery by up to 15% due to reduced connectivity of erodible land to rivers and lakes. Results at local / farm scales could be as high as 80% in some locations. A 75% improvement in habitat for selected 21 indicator plant species was also projected. The inter-dependency between outcomes is being explored through a major integrated rolling monitoring programme taking co-located measurements of soil, vegetation, landuse, soils, water, birds and pollinators, GHG fluxes, landscape and historic features and farmer / landowner surveys using a stratified sampling approach across the country. In addition to scenario analysis, modelling is being used to upscale and integrate findings and to explore the extent of co-benefits and trade-offs between outcomes e.g. using the LUCI model. The integrated monitoring and modelling approach will be presented together with an introduction to the model ensemble. Outputs from the initial scenario runs plus initial findings from the wider social and economic assessments and trade-off analysis will also be discussed.

    AIMS: To investigate the relevance of enuresis subtyping for selection of treatment modality and for long-term outcome in a large consecutive patient cohort. MATERIALS AND METHODS: We included all patients referred for urinary incontinence during a 5-year period but excluding recurrent urinary tract infections (UTI). Type and severity of incontinence, prior history, results of examinations performed, number of visits, and effect of all treatments provided, were included in a clinical database. RESULTS: Seven hundred twenty children aged 4-16 years (mean 8.5?±?2.2?years, 239 girls) were included in the analysis (42% with monosymptomatic (MNE), 55% with non-MNE, and 3% with isolated daytime incontinence). Initial evaluation revealed only few underlying causes (one neurological and eight anatomical). Investigations showed significant differences between MNE and non-MNE patients as both maximal voided volume and nocturnal urine volume was lower in non-MNE patients (P?

    To describe the details of the foraminoplastic superior vertebral notch approach (FSVNA) with reamers in percutaneous endoscopic lumbar discectomy (PELD) and to demonstrate the clinical outcomes in limited indications of PELD. Retrospective data were collected from 64 patients who underwent PELD with FSVNA from August 2012 to April 2014. Inclusion criteria were high grade migrated disc, high canal compromised disc, and disc protrusion combined with foraminal stenosis. The clinical outcomes were assessed using by the visual analogue scale (VAS), Oswestry Disability Index (ODI) and modified MacNab criteria. Complications related to the surgery were reviewed. The procedure used a unique approach, using the superior vertebral notch as the target and performing foraminoplasty with only reamers under C-arm control. The mean age of the 55 female and 32 male patients was 52.73 years. The mean F/U period was 12.2±4.2 months. Preoperative VAS (8.24±1.25) and ODI (67.8±15.4) score improved significantly at the last follow-up (VAS, 1.93±1.78; ODI, 17.14±15.7). Based on the modified MacNab criteria, excellent or good results were obtained in 95.3% of the patients. Postoperative transient dysthesia (n=2) and reoperation (n=1) due to recurred disc were reported. PELD with FSVNA could be a good method for treating lumbar disc herniation. This procedure may offer safe and efficacious results, especially in the relatively limited indications for PELD.

  2. The effect of posterior and lateral approach on patient-reported outcome measures and physical function in patients with osteoarthritis, undergoing total hip replacement : a randomised controlled trial protocol

    Rosenlund, Signe; Broeng, Leif

    2014-01-01

    BACKGROUND: Total hip replacement provides pain relief and improves physical function and quality of life in patients with end-stage hip osteoarthritis. The incidence of hip replacement operations is expected to increase due to the growing elderly population. Overall, the posterior approach and lateral approach are the two most commonly used approaches for hip replacement operations. The posterior approach is associated with an increased risk of revision due to dislocations, and some studies have shown that the lateral approach is associated with reduced patient-reported outcomes, including physical function and pain; however, this has not been investigated in a randomised controlled trial with a twelve-month follow-up. We hypothesized that the lateral approach has an inferior outcome in patient-reported outcome compared with the posterior approach after one year. METHODS/DESIGN: The trial is a prospective, double blinded, parallel-group controlled trial with balanced randomisation [1: 1]. Patients with hip osteoarthritis scheduled for hip replacement surgery, aged 45-70 years, will be consecutively recruited and randomised into two groups. Group A will receive hip replacement using the posterior approach, and Group B will receive hip replacement using the lateral approach. The primary end-point for assessing the outcome of the two interventions will be twelve months after surgery. Follow-up will also be performed after three and six months. The primary outcome is Hip Disability and Osteoarthritis Outcome Score, subscale of "Physical function Short form" (HOOS-PS) Secondary outcome measures include two other subscales of HOOS ("Pain" and "Hip related Quality of Life"), physical activity level (UCLA activity score), limping (HHS) and general health status (EQ-5D-3L). Explorative outcomes include physical function test, 3D-gait-analysis and muscle strength. DISCUSSION: To our knowledge, this is the first randomised controlled trial comparing the posterior approach with the lateral approach with patient reported outcome as the primary outcome and with a twelve-month follow-up.

    Most commercial visualization tools support an easy and quick creation of conventional time-oriented visualizations such as line charts, but customization is limited. In contrast, some academic visualization tools and programming languages support the creation of some customizable time-oriented visualizations but it is time consuming and hard. To combine efficiency, the effort required to develop a visualization, and customizability, the ability to tailor a visualization, we developed time-oriented building blocks that address the specifics of time (e.g. linear vs. cyclic or point-based vs. interval-based) and consist of inner customizable parts (e.g. ticks). A combination of the time-oriented and other primitive graphical building blocks allowed the creation of several customizable advanced time-oriented visualizations. The appearance and behavior of the blocks are specified using spreadsheet-like formulas. We compared our approach with other popular visualization tools. Evaluation showed that our approachrates well in customizability.

  5. An investigation of nursing competence and the competency outcomes performance assessment curricular approach: senior students' self-reported perceptions.

    Klein, Colleen J; Fowles, Eileen R

    2009-01-01

    This study was designed to measure the construct of competence as perceived by nursing students in different programs of study. An exploration of a competence-based curricular model was undertaken to determine if there are distinguishing differences between schools that have formally adopted Dr. Carrie Lenburg's Competency Outcomes Performance Assessment (COPA) model as a curricular guide and those who have do not have a formal competence model guiding the curriculum. The Six-Dimension Scale of Nursing Performance (6-D Scale) was used to evaluate nursing competence. Using a purposive sample, senior nursing students (N = 391) from three different types of nursing programs (baccalaureate, associate [ADN], and diploma) were surveyed. Students completed a two-part questionnaire that included the 6-D Scale, demographic questions, and a researcher-generated questionnaire designed to measure competency-based learning and evaluation. Faculty (n = 101) from these same programs were also surveyed. The results revealed that students from COPA and non-COPA schools reported slightly lower scores in three subscales: teaching/collaboration, critical care, and leadership. Significant curricular differences as defined by the Klein Scales were found between COPA and non-COPA senior students, with 17% to 30% of the variance explained for the COPA students. The findings reflect that baccalaureate students reported significantly lower 6-D Scale scores in multiple areas when compared to diploma and ADN students. Enhancement of student learning and curricular revisions designed to improve leadership and technical expertise are suggested by the findings of this study. PMID:19306834

    The Bundlab software has been developed mainly for academic and research application. This work can be treated as a kind of a report describing the current state of the development of this computer program, focusing especially on the analytical solutions. Firstly, the overall characteristics of the software are provided. Then the description of the image orientation procedure starting from the relative orientation is addressed. The applied solution is based on the coplanarity equation parametrized with the essential matrix. The problem is reformulated in order to solve it using methods of algebraic geometry. The solution is followed by the optimization involving the least square criterion. The formation of the image block from the oriented models as well as the absolute orientation procedure were implemented using the Horn approach as a base algorithm. The second part of the paper is devoted to the tools and methods applied in the stereo digitization module. The solutions that support the user and improve the accuracy are given. Within the paper a few exemplary applications and products are mentioned. The work finishes with the concepts of development and improvements of existing functions.

    Boris Petrovitch Zakharchenya (1928-2005) This issue is dedicated to the memory of Boris Petrovich Zakharchenya, who died at the age of 77 in April 2005. He was an eminent scientist and a remarkable man. After studying physics at Leningrad University he joined the Physico-Technical Institute (now the A F Ioffe Institute) in 1952 and became the co-worker of Evgeny Feodorovich Gross, shortly after the exciton was discovered in his laboratory. The experiments on cuprous oxide crystals in the visible spectral range showed a hydrogen-like spectrum, which was interpreted as excitonic absorption. The concept of the exciton had been conceived some years earlier by Jacov Frenkel at the Physico-Technical Institute. Immediately after joining Gross, Zakharchenya succeeded in producing spectra of unprecedented quality. Subsequently the heavy and the light hole series were found. Also, Landau splitting was discovered when a magnetic field was applied. The interpretation of the discovery was thrown into doubt by Russian colleagues and it took some time, before the correct interpretation prevailed. Shortly before his death, Boris wrote the history of the discovery of the exciton, which has recently been published in Russian in a book celebrating the 80th anniversary of his birth [1]. The book also contains essays by Boris on various themes, not only on physics, but also on literature. Boris was a man of unusually wide interests, he was not only fascinated by physics, but also loved literature, art and music. This can be seen in the first article of this issue The Play of Light in Crystals which is an abbreviated version of his more complete history of the discovery of the exciton. It also gives a good impression of the personality of Boris. One of us (GL) had the privilege to become closely acquainted with him, while he was a guest professor at the University of Würzburg. During that time we had many discussions, and I recall his continuing rage on the wrong attribution of the priority of the discovery in the literature, which was partly caused by the existence of the Iron Curtain. I had already enjoyed contact with Boris in the 1980s when the two volumes of Landau Level Spectroscopy were being prepared [2]. He was one of the pioneers of magneto-optics in semiconductors. In the 1950s the band structure of germanium and silicon was investigated by magneto-optical methods, mainly in the United States. No excitonic effects were observed and the band structure parameters were determined without taking account of excitons. However, working with cuprous oxide, which is a direct semiconductor with a relative large energy gap, Zakharchenya and his co-worker Seysan showed that in order to obtain correct band structure parameters, it is necessary to take excitons into account [3]. About 1970 Boris started work on optical orientation. Early work by Hanle in Germany in the 1920s on the depolarization of luminescence in mercury vapour by a transverse magnetic field was not appreciated for a long time. Only in the late 1940s did Kastler and co-workers in Paris begin a systematic study of optical pumping, which led to the award of a Nobel prize. The ideas of optical pumping were first applied by Georges Lampel to solid state physics in 1968. He demonstrated optical orientation of free carriers in silicon. The detection method was nuclear magnetic resonance; optically oriented free electrons dynamically polarized the 29Si nuclei of the host lattice. The first optical detection of spin orientation was demonstrated by with the III-V semiconductor GaSb by Parsons. Due to the various interaction mechanisms of spins with their environment, the effects occurring in semiconductors are naturally more complex than those in atoms. Optical detection is now the preferred method to detect spin alignment in semiconductors. The orientation of spins in crystals pumped with circularly polarized light is deduced from the degree of circular polarization of the recombination radiation. The major results of the systematic work on optical orientation, both experimental and

    This study compared costs and clinical outcomes of invasive versus non-invasive diagnostic evaluations for patients with suspected in-stent restenosis (ISR) after percutaneous coronary intervention. We developed a decision model to compare 2 year diagnosis-related costs for patients who presented with suspected ISR and were evaluated by: (1) invasive coronary angiography (ICA); (2) non-invasive stress testing strategy of myocardial perfusion imaging (MPI) with referral to ICA based on MPI; (3) coronary CT angiography-based testing strategy with referral to ICA based on CCTA. Costs were modeled from the payer's perspective using 2014 Medicare rates. 56 % of patients underwent follow-up diagnostic testing over 2 years. Compared to ICA, MPI (98.6 %) and CCTA (98.1 %) exhibited lower rates of correct diagnoses. Non-invasive strategies were associated with reduced referrals to ICA and costs compared to an ICA-based strategy, with diagnostic costs lower for CCTA than MPI. Overall 2-year costs were highest for ICA for both metallic as well as BVS stents ($1656 and $1656, respectively) when compared to MPI ($1444 and $1411) and CCTA. CCTA costs differed based upon stent size and type, and were highest for metallic stents >3.0 mm followed by metallic stents  3.0 mm ($1466 vs. $1242 vs. $855 vs. $490, respectively). MPI for suspected ISR results in lower costs and rates of complications than invasive strategies using ICA while maintaining high diagnostic performance. Depending upon stent size and type, CCTA results in lower costs than MPI. PMID:26335370

    2015-11-01

    The introduction of next-generation sequencing in everyday clinical genetics practise is increasing the number of genetic disorders that can be confirmed at DNA-level, and consequently increases the possibilities for cascade screening. This leads to a greater need for genetic counselling, whereas the number of professionals available to provide this is limited. We therefore piloted group genetic counselling for symptomatic cardiomyopathy patients at regional hospitals, to assess whether this could be an acceptable alternative to individual counselling. We performed a cohort study with pre- and post-counselling patient measurements using questionnaires, supplemented with evaluations of the group counselling format by the professionals involved. Patients from eight regional hospitals in the northern part of the Netherlands were included. Questionnaires comprised patient characteristics, psychological measures (personal perceived control (PPC), state and trait anxiety inventory (STAI)), and satisfaction with counsellors, counselling content and design. In total, 82 patients (mean age 57.5 year) attended one of 13 group sessions. Median PPC and STAI scores showed significantly higher control and lower anxiety after the counselling. Patients reported they were satisfied with the counsellors, and almost 75% of patients were satisfied with the group counselling. Regional professionals were also, overall, satisfied with the group sessions. The genetics professionals were less satisfied, mainly because of their perceived large time investment and less-than-expected group interaction. Hence, a group approach to cardiogenetic counselling is feasible, accessible, and psychologically effective, and could be one possible approach to counselling the increasing patient numbers in cardiogenetics.

  19. A log-linear modelling approach to assessing the consistency of ego reports of dyadic outcomes with applications to fertility and sexual partnerships

    Admiraal, Ryan; Handcock, Mark S.

    2015-01-01

    Summary We propose a log-linear model to assess the consistency of ego reports of dyadic outcomes. We do so specifically in the context where males and females report on shared events, and we demonstrate how inconsistencies can be assessed by using a log-linear model that estimates separate mixing totals for each set of reports. This modelling approach immediately allows us to determine where inconsistencies in reports occur. To demonstrate how our method can be easily implemented for survey data, we apply it to both the 1992 National Health and Social Life Survey and the 2002 National Survey of Family Growth. Our analysis identifies inconsistencies in male and female reports of concurrent partnerships and the number of biological children.

  20. Measuring social value orientation

    2011-12-01

    Full Text Available Narrow self-interest is often used as a simplifying assumption when studying people making decisions in social contexts. Nonetheless, people exhibit a wide range of different motivations when choosing unilaterally among interdependent outcomes. Measuring the magnitude of the concern people have for others, sometimes called Social Value Orientation (SVO, has been an interest of many social scientists for decades and several different measurement methods have been developed so far. Here we introduce a new measure of SVO that has several advantages over existent methods. A detailed description of the new measurement method is presented, along with norming data that provide evidence of its solid psychometric properties. We conclude with a brief discussion of the research streams that would benefit from a more sensitive and higher resolution measure of SVO, and extend an invitation to others to use this new measure which is freely available.
