    Here, we report a new and diversity-oriented approach to macrocyclic cyclophanes by a Grignard reaction, followed by Fischer indolization and ring-closing metathesis (RCM) as key steps. The configuration of the double bond formed during the RCM depends upon the order of synthetic sequence used. Fischer indolization followed by RCM delivers the cis isomer, whereas RCM followed by Fischer indolization gives the trans isomer. PMID:26317873

    A study was conducted to examine the influence of a risk-oriented future self on self-reported marijuana use among college students. Drawing on theoretical work on possible selves, it was hypothesized that the extent to which a future self is viewed as risk-oriented will be associated with reported marijuana use and that effects of a risk-oriented future self on use would be partially mediated by risk-oriented attitudes and perceived attractiveness of users. Analysis of data from an online survey of college students supported hypotheses, with the additional finding that the effect of user attractiveness on use is mediated by attitudes.

    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.

    2011-04-01

    Stressors and demands related to changes in work environment may result in impairments of employees' health and ability to work. In the context of the German statutory pension insurance's inpatient medical rehabilitation, these aspects are increasingly taken into account within the concept of vocationally oriented medical rehabilitation (VOMR). Nonetheless, a comprehensive implementation of diagnostic and therapeutic concepts in rehabilitative practice has not yet been realized. In this article, a profile of requirements for VOMR which has been developed by the German pension insurance is introduced that shall contribute to aligning rehabilitative measures for patients with work-related problems with occupational demands. Moreover, approaches for implementing vocationally oriented measures in diagnostics (e.g., screenings) and therapy (e.g., job training) as well as good practice examples are presented. In addition, user-oriented media (handbook, homepage) which enable researchers and clinicians to learn about the current state of research in this area are highlighted. Starting points for further development of vocational orientation in rehabilitation are discussed. PMID:21465399

  12. Approach for Improving the Integrated Sensor Orientation

    2016-06-01

    The direct determination of exterior orientation parameters (EOP) of aerial images via integration of the Inertial Measurement Unit (IMU) and GPS is often used in photogrammetric mapping nowadays. The accuracies of the EOP depend on the accurate parameters related to sensors mounting when the job is performed (offsets of the IMU relative to the projection centre and the angles of boresigth misalignment between the IMU and the photogrammetric coordinate system). In principle, when the EOP values do not achieve the required accuracies for the photogrammetric application, the approach, known as Integrated Sensor Orientation (ISO), is used to refine the direct EOP. ISO approach requires accurate Interior Orientation Parameters (IOP) and standard deviation of the EOP under flight condition. This paper investigates the feasibility of use the in situ camera calibration to obtain these requirements. The camera calibration uses a small sub block of images, extracted from the entire block. A digital Vexcel UltraCam XP camera connected to APPLANIX POS AVTM system was used to get two small blocks of images that were use in this study. The blocks have different flight heights and opposite flight directions. The proposed methodology improved significantly the vertical and horizontal accuracies of the 3D point intersection. Using a minimum set of control points, the horizontal and vertical accuracies achieved nearly one image pixel of resolution on the ground (GSD). The experimental results are shown and discussed.

    2016-06-01

    It is important to understand the change processes involved in psychotherapies for patients with personality disorders (PDs). One patient process that promises to be useful in relation to the outcome of psychotherapy is emotional processing. In the present process-outcome analysis, we examine this question by using a sequential model of emotional processing and by additionally taking into account a therapist's appropriate responsiveness to a patient's presentation in clarification-oriented psychotherapy (COP), a humanistic-experiential form of therapy. The present study involved 39 patients with a range of PDs undergoing COP. Session 25 was assessed as part of the working phase of each therapy by external raters in terms of emotional processing using the Classification of Affective-Meaning States (CAMS) and in terms of the overall quality of therapist-patient interaction using the Process-Content-Relationship Scale (BIBS). Treatment outcome was assessed pre- and post-therapy using the Global Severity Index (GSI) of the SCL-90-R and the BDI. Results indicate that the good outcome cases showed more self-compassion, more rejecting anger, and a higher quality of therapist-patient interaction compared to poorer outcome cases. For good outcome cases, emotional processing predicted 18% of symptom change at the end of treatment, which was not found for poor outcome cases. These results are discussed within the framework of an integrative understanding of emotional processing as an underlying mechanism of change in COP, and perhaps in other effective therapy approaches for PDs.

    Actions are performed via utterance, and speech acts apply to speakers' communicative intention to produce an utterance, The simplest purpose of language learning is to communicate with others. Second language learners can have high-level of general language proficiency, when it comes to communicate they might encounter kinds of problems. This paper will discuss a point that it' s whether or not for language learners to speak fluently and sensitively a pragmatic-oriented approach more effective than traditional method. Pragmatic use of language is definitely different from syntactic use of language, Pragmatic training is that essential in teaching environment, for it' s absolute not just to tell learners how to design an idea and organize a sentence, but to instruct learners to say which utterance being proper and appropriate for a certain condition.

    Full Text Available Several Agent Oriented Software Engineering (AOSE methodologies were proposed to build open, heterogeneous and complex internet based systems. AOSE methodologies offer different conceptual frameworks, notations and techniques, thereby provide a platform to make the system abstract, generalize, dynamic and autonomous. Lifecycle coverage is one of the important criteria for evaluating an AOSE methodology. Most of the existing AOSE methodologies focuses only on analysis, design, implementation and disregarded testing, stating that the testing can be done by extending the existing objectoriented testing techniques. Though objects and agents have some similarities, they both differ widely. Role is an important attribute of an agent that has a huge scope and support for the analysis, design and implementation of Multi-Agent System (MAS. The main objective of the paper is to extend the scope and support of role towards testing, thereby the vacancy for software testing perception in the AOSE series will be filled up. This paper presents an overview of role based testing based on the V-Model in order to add the next new component as of AgentOriented Software testing in the agent oriented development life cycle.

  19. Marketing-oriented organizations: an integrated approach.

    Science.gov (United States)

    Stensrud, R; Arrington, B

    1988-03-01

    Organizations can be oriented toward marketing from a production, product, sales, or marketing perspective. Strategies, structures, and cultures, which reflect a company's basic orientation, must be integrated to ensure that marketing efforts communicate a clear corporate position. In a study of 31 hospitals, the Center for Health Services Education Research, St. Louis University, found that no hospital's organization fit neatly into a single category. For example, a hospital may have some service lines that were marketing oriented while other lines were production oriented. The majority of hospitals, however, were product oriented, focusing on productivity and financial performance rather than on market factors. The most effective sales orientation was observed in the for-profits. Their selling efforts, however, tended to be internally focused, with product development activities divorced from the planning and marketing functions. Only the for-profit hospitals showed the beginning of a marketing orientation. Developing a marketing orientation, especially in line divisions, requires a careful, well-orchestrated effort and the presence of several key factors: Access to capital and an emphasis on long-range planning and strategic spending The availability of hospital-specific market research. Key distribution channels. Talented middle managers. Up-to-date systems and structures equipped to serve new values and strategies. Leaders capable of communicating to the organization a vision of its role in the community. PMID:10302251

    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.

  4. Risk evaluation: A cost-oriented approach

    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

  7. A Roles-based Approach To Variable-oriented Programming

    Directory of Open Access Journals (Sweden)

    Juha Sorva

    2008-01-01

    Full Text Available Delocalized variable plans pose problems for novice programmers trying to read and write programs. Variable-oriented programming is a programming paradigm that emphasizes the importance of variable-related plans, and localizes actions pertaining to each variable together in one place in the program code. This paper revisits the idea of variable-oriented programming and shows how it can be founded on roles of variables: stereotypes of variable use suitable for teaching to novices. The paper sketches out how variable-oriented, roles-based programming could be implemented using either a new programming language or a framework built on an existing language. The possible applications, merits, and problems of a roles-based approach, and variable-oriented programming in general, are discussed. This paper points toward possible research directions for the future and provides a basis for further discussions of variable-oriented, roles-based programming.

    Outcomes and effectiveness research has provided a wealth of information about interventions that can improve patient experience and outcomes. The challenges facing healthcare leaders today highlight the need for new research on how leadership and management principles can enable healthcare providers and systems to deploy this knowledge swiftly and effectively. The Baldrige National Quality Program (BNQP) is an education and award program established by the U.S. Congress in 1987 that supports American businesses seeking to improve product and service quality, customer and workforce satisfaction, efficiency, financial results, and overall capacity to perform and respond to changing circumstances. Award recipients show a constellation of strengths that suggest that certain basic leadership and management practices are correlated with a fundamental ability to achieve desired results. This article describes characteristics of highly effective organizations based on a review of Baldrige Award recipients, focuses on the application of these characteristics to healthcare settings, illustrates their application with best practices from SSM Health Care, the first-ever healthcare recipient in 2002, and presents several priorities for outcomes and effectiveness research to inform healthcare leadership and administration.

    The attractive feature of Service Oriented Architecture (SOA) is that pieces of software conceived and developed by independent organizations can be dynamically composed to provide richer functionality. The same reasons that enable flexible compositions, however, also prevent the application of some traditional testing approaches, making SOA validation challenging and costly. Web services usually expose just an interface, enough to invoke them and develop some general (black-box) tests, but i...

    1996-01-01

    In Data-Oriented Parsing (DOP), an annotated language corpus is used as a stochastic grammar. The most probable analysis of a new input sentence is constructed by combining sub-analyses from the corpus in the most probable way. This approach has been succesfully used for syntactic analysis, using corpora with syntactic annotations such as the Penn Treebank. If a corpus with semantically annotated sentences is used, the same approach can also generate the most probable semantic interpretation of an input sentence. The present paper explains this semantic interpretation method, and summarizes the results of a preliminary experiment. Semantic annotations were added to the syntactic annotations of most of the sentences of the ATIS corpus. A data-oriented semantic interpretation algorithm was succesfully tested on this semantically enriched corpus.

    Full Text Available In this era of fast paced technological advancements, security issues and risks related to it have become a key concern for all organizations. Enterprise Governance, Risk management and Compliance(GRC is the popular approach to handle enterprise risks and reduce its impact. This paper focuses on the risk management, especially the risk assessment approaches and proposes an aspect oriented approach to risk management. In this approach, the risk management processes are designed separately from the core business processes and are weaved to the flow of business process steps wherever necessary.This brings the advantage of separation of concerns of risk management from the business process. The design of business processes then need not look into the design of risk assessment related to it. This will enable handling of risk and its assessment by expert risk advisories, those who are specialized in it.

  10. Modeling Water Shortage Management Using an Object-Oriented Approach

    As a result of the increasing global population and the resulting urbanization, water shortage issues have received increased attention throughout the world . Water supply has not been able to keep up with increased demand for water, especially during times of drought. The use of an object-oriented (OO) approach coupled with efficient mathematical models is an effective tool in addressing discrepancies between water supply and demand. Object-oriented modeling has been proven powerful and efficient in simulating natural behavior. This research presents a way to model water shortage management using the OO approach. Three groups of conceptual components using the OO approach are designed for the management model. The first group encompasses evaluation of natural behaviors and possible related management options. This evaluation includes assessing any discrepancy that might exist between water demand and supply. The second group is for decision making which includes the determination of water use cutback amount and duration using established criteria. The third group is for implementation of the management options which are restrictions of water usage at a local or regional scale. The loop is closed through a feedback mechanism where continuity in the time domain is established. Like many other regions, drought management is very important in south Florida. The Regional Simulation Model (RSM) is a finite volume, fully integrated hydrologic model used by the South Florida Water Management District to evaluate regional response to various planning alternatives including drought management. A trigger module was developed for RSM that encapsulates the OO approach to water shortage management. Rigorous testing of the module was performed using historical south Florida conditions.

  11. Process-outcome interrelationship and standard setting in medical education: the need for a comprehensive approach.

    Christensen, Leif; Karle, Hans; Nystrup, Jørgen

    2007-09-01

    An outcome-based approach to medical education compared to a process/content orientation is currently being discussed intensively. In this article, the process and outcome interrelationship in medical education is discussed, with specific emphasis on the relation to the definition of standards in basic medical education. Perceptions of outcome have always been an integrated element of curricular planning. The present debate underlines the need for stronger focus on learning objectives and outcome assessment in many medical schools around the world. The need to maintain an integrated approach of process/content and outcome is underlined in this paper. A worry is expressed about the taxonomy of learning in pure outcome-based medical education, in which student assessment can be a major determinant for the learning process, leaving the control of the medical curriculum to medical examiners. Moreover, curricula which favour reductionism by stating everything in terms of instrumental outcomes or competences, do face a risk of lowering quality and do become a prey for political interference. Standards based on outcome alone rise unclarified problems in relationship to licensure requirements of medical doctors. It is argued that the alleged dichotomy between process/content and outcome seems artificial, and that formulation of standards in medical education must follow a comprehensive line in curricular planning.

The authors of this proposal will learn the key issues of this approach:~~OO analysis and design. Several methodologies will be studied to select the most appropriate for the High Energy Physics case. Some Computer Aided Software Engineering tools and implementation languages will be evaluated. These studies will be carried out with various well-defined prototypes, some of which have been defined in a preceding study and some of which will be defined in the course of this R\\&D project. We propose to also study in this project how the OO approach enhances a different, and hopefully better, project management. Management tools will be tried and professional training will be organized.

    2013-08-01

    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.

    Full Text Available Introduction. The evaluation of community action is an advisable practice in community work, that can help to properly manage resources and to improve social and educational interventions. Participation-oriented evaluation approaches are an opportunity to evaluate community action relying involving all stakeholders, not just those with technical background and skills. With the basis provided by the information of international literature on the subject, in this paper we make a theoretical analysis of participation-oriented evaluation approaches, with three goals: to justify its relevance in the evaluation of community actions; to present the specific characteristics of the most cited participatory approaches in that literature, and to clarify their shared characteristics. Method. We carried out a systematic review and analysis of articles published in international journals on evaluation and community development since 2000. Results. The results present the specific features of four approaches used in the field of evaluation of community actions: (1 Collaborative evaluation; (2 Practical-Participatory Evaluation; (3 Transformative-Participatory evaluation; and (4 Empowerment Evaluation; and the characteristics shared by these four methods, besides other approaches referenced in the bibliography attached, which are focused on the participation of people.Conclusions. From our point of view, the models that best fit the socio-educational approaches to community action are the Transformative-Participatory Evaluation and the Empowerment Evaluation. The Participatory Evaluation in which we frame our actions is the one that allows us to change and to acquire in this process, new powers that allow us to transform the reality we are living in.

  15. A ROle-Oriented Filtering (ROOF) approach for collaborative recommendation

    Science.gov (United States)

    Ghani, Imran; Ryul Jeong, Seung

    2016-09-01

    In collaborative filtering (CF) recommender systems, existing techniques frequently focus on determining similarities among users' historical interests. This generally refers to situations in which each user normally plays a single role and his/her taste remains consistent over the long term. However, we note that existing techniques have not been significantly employed in a role-oriented context. This is especially so in situations where users may change their roles over time or play multiple roles simultaneously, while still expecting to access relevant information resources accordingly. Such systems include enterprise architecture management systems, e-commerce sites or journal management systems. In scenarios involving existing techniques, each user needs to build up very different profiles (preferences and interests) based on multiple roles which change over time. Should this not occur to a satisfactory degree, their previous information will either be lost or not utilised at all. To limit the occurrence of such issues, we propose a ROle-Oriented Filtering (ROOF) approach focusing on the manner in which multiple user profiles are obtained and maintained over time. We conducted a number of experiments using an enterprise architecture management scenario. In so doing, we observed that the ROOF approach performs better in comparison with other existing collaborative filtering-based techniques.

    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.

  19. A Formal Approach to Domain-Oriented Software Design Environments

    Lowry, Michael; Philpot, Andrew; Pressburger, Thomas; Underwood, Ian; Lum, Henry, Jr. (Technical Monitor)

    1994-01-01

    This paper describes a formal approach to domain-oriented software design environments, based on declarative domain theories, formal specifications, and deductive program synthesis. A declarative domain theory defines the semantics of a domain-oriented specification language and its relationship to implementation-level subroutines. Formal specification development and reuse is made accessible to end-users through an intuitive graphical interface that guides them in creating diagrams denoting formal specifications. The diagrams also serve to document the specifications. Deductive program synthesis ensures that end-user specifications are correctly implemented. AMPHION has been applied to the domain of solar system kinematics through the development of a declarative domain theory, which includes an axiomatization of JPL's SPICELIB subroutine library. Testing over six months with planetary scientists indicates that AMPHION's interactive specification acquisition paradigm enables users to develop, modify, and reuse specifications at least an order of magnitude more rapidly than manual program development. Furthermore, AMPHION synthesizes one to two page programs consisting of calls to SPICELIB subroutines from these specifications in just a few minutes. Test results obtained by metering AMPHION's deductive program synthesis component are examined. AMPHION has been installed at JPL and is currently undergoing further refinement in preparation for distribution to hundreds of SPICELIB users worldwide. Current work to support end-user customization of AMPHION's specification acquisition subsystem is briefly discussed, as well as future work to enable domain-expert creation of new AMPHION applications through development of suitable domain theories.

    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.

  4. Mutation Analysis Approach to Develop Reliable Object-Oriented Software

    Monalisa Sarma

    2014-01-01

    Full Text Available In general, modern programs are large and complex and it is essential that they should be highly reliable in applications. In order to develop highly reliable software, Java programming language developer provides a rich set of exceptions and exception handling mechanisms. Exception handling mechanisms are intended to help developers build robust programs. Given a program with exception handling constructs, for an effective testing, we are to detect whether all possible exceptions are raised and caught or not. However, complex exception handling constructs make it tedious to trace which exceptions are handled and where and which exceptions are passed on. In this paper, we address this problem and propose a mutation analysis approach to develop reliable object-oriented programs. We have applied a number of mutation operators to create a large set of mutant programs with different type of faults. We then generate test cases and test data to uncover exception related faults. The test suite so obtained is applied to the mutant programs measuring the mutation score and hence verifying whether mutant programs are effective or not. We have tested our approach with a number of case studies to substantiate the efficacy of the proposed mutation analysis technique.

    Liao, Hui; Rupp, Deborah E

    2005-03-01

    In this article, which takes a person-situation approach, the authors propose and test a cross-level multifoci model of workplace justice. They crossed 3 types of justice (procedural, informational, and interpersonal) with 2 foci (organization and supervisor) and aggregated to the group level to create 6 distinct justice climate variables. They then tested for the effects of these variables on either organization-directed or supervisor-directed commitment, satisfaction, and citizenship behavior. The authors also tested justice orientation as a moderator of these relationships. The results, based on 231 employees constituting 44 work groups representing multiple organizations and occupations, revealed that 4 forms of justice climate (organization-focused procedural and informational justice climate and supervisor-focused procedural and interpersonal justice climate) were significantly related to various work outcomes after controlling for corresponding individual-level justice perceptions. In addition, some moderation effects were found. Implications for organizations and future research are discussed. PMID:15769235

    Full Text Available This article analyzes the main approaches to study educational and occupational outcomes and trajectories. Young people have to decide when and what to study, later on, where to work. Their life levels will depend on those decisions, but the different ways that in both areas they are able to take and their outcomes in education and in the labor market depend on various factors. Among explications it is possible to identify six large approaches: human capital from economics, cultural and social capital from sociology, the socioeconomic status or familiar background approach and the educational and psychological approaches. These approaches are not contrary necessarily, they can be complementary, and their explanatory power depends on place and time, however, the literature does not have an effort to present together their contributions, methodologies and empirical results. This work seeks to remedy that situation and to point out some methodological and empirical weakness.

    The Superconducting Super Collider (SSC) in Texas, the construction of which was stopped in 1994, would have represented a major challenge in accelerator research and development. This paper addresses the issues encountered in the parallel design and construction of the control systems for the RF equipment for the five accelerators comprising the SSC. An extensive analysis of the components of the RF control systems has been undertaken, based upon the Schlaer-Mellor object-oriented analysis and design (OOA/OOD) methodology. The RF subsystem components such as amplifiers, tubes, power supplies, PID loops, etc. were analyzed to produce OOA information, behavior and process models. Using these models, OOD was iteratively applied to develop a generic RF control system design. This paper describes the results of this analysis and the development of bridges' between the analysis objects, and the EPICS-based software and underlying VME-based hardware architectures. The application of this approach to several of the SSCL RF control systems is discussed. ((orig.))

    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

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.

  11. 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

  12. A Distributed Trajectory-Oriented Approach to Managing Traffic Complexity

    2007-01-01

    In order to handle the expected increase in air traffic volume, the next generation air transportation system is moving towards a distributed control architecture, in which ground-based service providers such as controllers and traffic managers and air-based users such as pilots share responsibility for aircraft trajectory generation and management. While its architecture becomes more distributed, the goal of the Air Traffic Management (ATM) system remains to achieve objectives such as maintaining safety and efficiency. It is, therefore, critical to design appropriate control elements to ensure that aircraft and groundbased actions result in achieving these objectives without unduly restricting user-preferred trajectories. This paper presents a trajectory-oriented approach containing two such elements. One is a trajectory flexibility preservation function, by which aircraft plan their trajectories to preserve flexibility to accommodate unforeseen events. And the other is a trajectory constraint minimization function by which ground-based agents, in collaboration with air-based agents, impose just-enough restrictions on trajectories to achieve ATM objectives, such as separation assurance and flow management. The underlying hypothesis is that preserving trajectory flexibility of each individual aircraft naturally achieves the aggregate objective of avoiding excessive traffic complexity, and that trajectory flexibility is increased by minimizing constraints without jeopardizing the intended ATM objectives. The paper presents conceptually how the two functions operate in a distributed control architecture that includes self separation. The paper illustrates the concept through hypothetical scenarios involving conflict resolution and flow management. It presents a functional analysis of the interaction and information flow between the functions. It also presents an analytical framework for defining metrics and developing methods to preserve trajectory flexibility and

    Circular orientation cages have been used for several decades to record the migratory orientation of passerine migrants, and have been central to the investigation of the functional characteristics of the biological compasses used for orientation. The use of these cages offers unique possibilities to study the migratory behaviour of songbirds, but suffers from statistical limitations in evaluating the directions of the activity recorded in the cages. The migratory activity has been reported to vary, including complex multimodal orientation of migratory passerines tested in orientation cages irrespective of species studied. The currently applied circular statistical methods fail to describe orientation responses differing from unimodal and axial distributions. We propose for the first time a modelling procedure enabling the analysis of multimodal distributions at either an individual or a group level. In this paper we compare the results of conventional methods and the recommended modelling approach. Migratory routes may be more complex than a simple migratory direction, and multimodal behaviour in migratory species at the individual and population levels can be advantageous. Individuals may select the expected migratory direction, but may also return to safer sites en route, i.e. sites already known, which provide food and/or shelter in reverse directions. In individual birds, several directions may be expressed in the same test hour. At the species level, multimodal orientation may give an opportunity to expand the range or may refer to differential migration route preferences in different populations of birds. A conflicting experimental situation may also result in a different preferential orientation. In this paper we suggest a statistical solution to deal with these types of variations in orientation preference.

    Full Text Available In this study, the pixel-based and object-oriented image classification approaches were used for identifying different land use types in Karnal district. Imagery from Landsat-7 ETM with 6 spectral bands was used to perform the image classification.Ground truth data were collected from the available maps, personal knowledge and communication with the local people. In order to prepare land use map different approaches: Artificial Neural Network(ANN and Support Vector Machine (SVM were used. For performing object oriented classification eCognition software was used. During the object oriented classification, in first step several differentsets of parameters were used for image segmentation and in second step nearest neighbor classifier was used for classification. Outcome from the classification works show that the object-oriented approach gave more accurate results (including higher producer’s and user’s accuracy for most of the land cover classes than those achieved by pixelbased classification algorithms. It is also observed that ANN performed better as compared to SVM classification approach.

  17. Verification of Object-Oriented Programs: a Transformational Approach

    CERN Document Server

    Apt, Krzysztof R; Olderog, Ernst-Ruediger

    2010-01-01

    We show that verification of object-oriented programs by means of the assertional method can be achieved in a simple way by exploiting a syntax-directed transformation from object-oriented programs to recursive programs. This transformation suggests natural proofs rules and its correctness helps us to establish soundness and relative completeness of the proposed proof system. One of the difficulties is how to properly deal in the assertion language with the instance variables and aliasing. The discussed programming language supports arrays, instance variables, failures and recursive methods with parameters.

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

    Directory of Open Access Journals (Sweden)

    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.

    2010-06-01

    This article describes a holistic approach to designing an introductory, object-oriented programming course. The design is grounded in constructivism and pedagogy of phenomenography. We use constructive alignment as the framework to align assessments, learning, and teaching with planned learning outcomes. We plan learning and teaching activities, and media with an understanding of variation theory and the ways in which students learn to program. We outline the implementation of the course, and discuss the findings from the first cycle of an action research study with a small sample of undergraduate students. An investigation of the preferred (deep/surface) learning approaches of the students led us to believe that these approaches can be influenced through course design. Personal constructs of the students, elicited through the repertory grid technique, revealed that rich inventories of learning resources are highly valued. We comment on the transformational processes of the experience of the participants, and identify areas for further refinement and investigation in the next action research cycle.

    Full Text Available Service Orientation Architecture is playing a vital role in the middleware and enterprise organizations through its key design principles and there are many benefits of it as well. Loose Coupling between services is one of its design principles that help system or architecture to maintain its efficiency because services are less dependent on each other. Stopping of one service could not affect other service and system but there is a fact that services have less knowledge of other services that’s why services cannot be able to properly communicate with each other and Service Oriented Architecture is totally based on communicative messages between services in order to perform their functionality. This paper provides a basic solution to control the messaging criteria between services. This paper holds the brief description of messaging criteria of services in service oriented architecture by defining the process of message that fulfills the guaranteed delivery of message to its other end while communicating or asking for a service.

    Multivariate random effects meta-analysis (MRMA) is an appropriate way for synthesizing data from studies reporting multiple correlated outcomes. In a Bayesian framework, it has great potential for integrating evidence from a variety of sources. In this paper, we propose a Bayesian model for MRMA of mixed outcomes, which extends previously developed bivariate models to the trivariate case and also allows for combination of multiple outcomes that are both continuous and binary. We have constructed informative prior distributions for the correlations by using external evidence. Prior distributions for the within-study correlations were constructed by employing external individual patent data and using a double bootstrap method to obtain the correlations between mixed outcomes. The between-study model of MRMA was parameterized in the form of a product of a series of univariate conditional normal distributions. This allowed us to place explicit prior distributions on the between-study correlations, which were constructed using external summary data. Traditionally, independent 'vague' prior distributions are placed on all parameters of the model. In contrast to this approach, we constructed prior distributions for the between-study model parameters in a way that takes into account the inter-relationship between them. This is a flexible method that can be extended to incorporate mixed outcomes other than continuous and binary and beyond the trivariate case. We have applied this model to a motivating example in rheumatoid arthritis with the aim of incorporating all available evidence in the synthesis and potentially reducing uncertainty around the estimate of interest.

  9. Action versus result-oriented schemes in a grassland agroecosystem: a dynamic modelling approach.

    Directory of Open Access Journals (Sweden)

    Rodolphe Sabatier

    Full Text Available Effects of agri-environment schemes (AES on biodiversity remain controversial. While most AES are action-oriented, result-oriented and habitat-oriented schemes have recently been proposed as a solution to improve AES efficiency. The objective of this study was to compare action-oriented, habitat-oriented and result-oriented schemes in terms of ecological and productive performance as well as in terms of management flexibility. We developed a dynamic modelling approach based on the viable control framework to carry out a long term assessment of the three schemes in a grassland agroecosystem. The model explicitly links grazed grassland dynamics to bird population dynamics. It is applied to lapwing conservation in wet grasslands in France. We ran the model to assess the three AES scenarios. The model revealed the grazing strategies respecting ecological and productive constraints specific to each scheme. Grazing strategies were assessed by both their ecological and productive performance. The viable control approach made it possible to obtain the whole set of viable grazing strategies and therefore to quantify the management flexibility of the grassland agroecosystem. Our results showed that habitat and result-oriented scenarios led to much higher ecological performance than the action-oriented one. Differences in both ecological and productive performance between the habitat and result-oriented scenarios were limited. Flexibility of the grassland agroecosystem in the result-oriented scenario was much higher than in that of habitat-oriented scenario. Our model confirms the higher flexibility as well as the better ecological and productive performance of result-oriented schemes. A larger use of result-oriented schemes in conservation may also allow farmers to adapt their management to local conditions and to climatic variations.

    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

  18. The impact of outcome orientation and justice concerns on tax compliance: the role of taxpayers' identity.

    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.

    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.

  1. 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.

    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.

    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.

  9. 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

Robust watermarks must be able to survive a range of geometrical “attacks,” such as image resizing, cropping, translation, rotation, scaling, smoothing, filtering, and simplification. In the current paper we extend existing approaches that are based partially on image invariant features; by introducing new image invariant features and exclusively using them. The proposed watermarking method is based on a combination of image processing techniques, theory of geometry, multiple image invariant features, and public key encryption. Experimental results show that the use of such combination of techniques allowed for securing the embedded watermark and for success in image watermark's recovery, if images were exposed to several geometrical attacks.

  11. 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.

    A flood risk assessment for coastal energy infrastructure in the UK with respect to long-term sea-level rise and extreme water levels has been conducted using a combination of numerical modelling approaches (LISFLOOD-FP, SWAB, XBeach-G, POLCOMS). Model outputs have been incorporated into a decision-support tool that enables users from a wide spectrum of coastal stakeholders (e.g. nuclear energy, utility providers, local government, environmental regulators, communities) to explore the potential impacts of flooding on both operational (events to 10 years) and strategic (10 to 50 years) timescales. Examples illustrate the physical and economic impacts of flooding from combined extreme water levels, wave overtopping and high river flow for Fleetwood, NW England; changes in the extent of likely flooding arising from an extreme event due to sea-level rise for Oldbury, SW England; and the relative vulnerability to overtopping and breaching of sea defences for Dungeness, SE England. The impacts of a potential large-scale beach recharge scheme to mitigate coastal erosion and flood risk along the southern shoreline of Dungeness are also examined using a combination of coastal evolution and particle-tracking modelling. The research goal is to provide an evidence base for resource allocation, investment in interventions, and communication and dialogue in relation to sea-level rise to 2500 AD.

    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.

    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

  17. The DPSIR Framework and a Pressure-Oriented Water Quality Monitoring Approach to Ecological River Restoration

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Without monitoring anthropogenic pressures on the water environment, it is difficult to set realistic river restoration targets in relation to water quality. Therefore a more holistic approach is needed to systematically explore the links between socio-economic drivers and observed water quality-related impacts on river ecosystems. Using the DPSIR (Drivers-Pressures-State of the Environment-Impacts-Responses framework, this study linked ecological river restoration with the socio-economic sector, with the focus on promoting a pressure-oriented water quality monitoring system. Based on the European Water Framework Directive (WFD and relevant literature, it was found that most water quality-related indicators employed today are state/impacts-oriented, while very few are pressure-oriented. As a response, we call for more attention to a DPR (Drivers-Pressures-Responses framework in developing an industrial ecology-based pressure-oriented water quality monitoring system for aiding ecological river restoration planning. This approach is characterized in general by accounting for material-related flows throughout the socio-economic sector in relation to river ecosystem degradation. Then the obtained information would help decision makers take appropriate measures to alleviate various significant human-induced wastes and emissions at their sources. We believe that such a pressure-oriented monitoring system will substantially complement traditional state/impacts-oriented environmental and ecological monitoring and help develop more proactive planning and decision-making processes for specific river restoration projects and general water quality management.

  19. 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.

    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-...

  2. Sharks modulate their escape behavior in response to predator size, speed and approach orientation.

    Science.gov (United States)

    Seamone, Scott; Blaine, Tristan; Higham, Timothy E

    2014-12-01

    Escape responses are often critical for surviving predator-prey interactions. Nevertheless, little is known about how predator size, speed and approach orientation impact escape performance, especially in larger prey that are primarily viewed as predators. We used realistic shark models to examine how altering predatory behavior and morphology (size, speed and approach orientation) influences escape behavior and performance in Squalus acanthias, a shark that is preyed upon by apex marine predators. Predator models induced C-start escape responses, and increasing the size and speed of the models triggered a more intense response (increased escape turning rate and acceleration). In addition, increased predator size resulted in greater responsiveness from the sharks. Among the responses, predator approach orientation had the most significant impact on escapes, such that the head-on approach, as compared to the tail-on approach, induced greater reaction distances and increased escape turning rate, speed and acceleration. Thus, the anterior binocular vision in sharks renders them less effective at detecting predators approaching from behind. However, it appears that sharks compensate by performing high-intensity escapes, likely induced by the lateral line system, or by a sudden visual flash of the predator entering their field of view. Our study reveals key aspects of escape behavior in sharks, highlighting the modulation of performance in response to predator approach. PMID:25041843

    2002-01-01

    The need to improve software productivity and software quality has put for-ward the research on software metrics technology and the development of software metrics toolto support related activities. To support object-oriented software metrics practice effectively,a model-based approach to object-oriented software metrics is proposed in this paper. Thisapproach guides the metrics users to adopt the quality metrics model to measure the object-oriented software products. The development of the model can be achieved by using a top-downapproach. This approach explicitly proposes the conception of absolute normalization computa-tion and relative normalization computation for a metrics model. Moreover, a generic softwaremetrics tool - Jade Bird Object-Oriented Metrics Tool (JBOOMT) is designed to implementthis approach. The parser-based approach adopted by the tool makes the information of thesource program accurate and complete for measurement. It supports various customizablehierarchical metrics models and provides a flexible user interface for users to manipulate themodels. It also supports absolute and relative normalization mechanisms in different situations.

    2016-09-01

    With the availability of advanced hydrologic data in public domain such as remote sensed and climate change scenario data, there is a need for a modeling framework that is capable of using these data to simulate and extend hydrologic processes with multidisciplinary approaches for sustainable water resources management. To address this need, a storage-release based distributed hydrologic model (STORE DHM) is developed based on an object-oriented approach. The model is tested for demonstrating model flexibility and extensibility to know how to well integrate object-oriented approach to further hydrologic research issues, e.g., reconstructing missing precipitation in this study, without changing its main frame. Moreover, the STORE DHM is applied to simulate hydrological processes with multiple classes in the Nanticoke watershed. This study also describes a conceptual and structural framework of object-oriented inheritance and aggregation characteristics under the STORE DHM. In addition, NearestMP (missing value estimation based on nearest neighborhood regression) and KernelMP (missing value estimation based on Kernel Function) are proposed for evaluating STORE DHM flexibility. And then, STORE DHM runoff hydrographs compared with NearestMP and KernelMP runoff hydrographs. Overall results from these comparisons show promising hydrograph outputs generated by the proposed two classes. Consequently, this study suggests that STORE DHM with an object-oriented approach will be a comprehensive water resources modeling tools by adding additional classes for toward developing through its flexibility and extensibility.

  18. The layer-oriented approach to declarative languages for biological modeling.

    Directory of Open Access Journals (Sweden)

    Ivan Raikov

    Full Text Available We present a new approach to modeling languages for computational biology, which we call the layer-oriented approach. The approach stems from the observation that many diverse biological phenomena are described using a small set of mathematical formalisms (e.g. differential equations, while at the same time different domains and subdomains of computational biology require that models are structured according to the accepted terminology and classification of that domain. Our approach uses distinct semantic layers to represent the domain-specific biological concepts and the underlying mathematical formalisms. Additional functionality can be transparently added to the language by adding more layers. This approach is specifically concerned with declarative languages, and throughout the paper we note some of the limitations inherent to declarative approaches. The layer-oriented approach is a way to specify explicitly how high-level biological modeling concepts are mapped to a computational representation, while abstracting away details of particular programming languages and simulation environments. To illustrate this process, we define an example language for describing models of ionic currents, and use a general mathematical notation for semantic transformations to show how to generate model simulation code for various simulation environments. We use the example language to describe a Purkinje neuron model and demonstrate how the layer-oriented approach can be used for solving several practical issues of computational neuroscience model development. We discuss the advantages and limitations of the approach in comparison with other modeling language efforts in the domain of computational biology and outline some principles for extensible, flexible modeling language design. We conclude by describing in detail the semantic transformations defined for our language.

  19. A Multidimensional Environmental Value Orientation Approach to Forest Recreation Area Tourism Market Segmentation

    Directory of Open Access Journals (Sweden)

    Cheng-Ping Wang

    2016-04-01

    Full Text Available This paper uses multidimensional environmental value orientations as the segmentation bases for analyzing a natural destination tourism market of the National Forest Recreation Areas in Taiwan. Cluster analyses identify two segments, Acceptance and Conditionality, within 1870 usable observations. Independent sample t test and crosstab analyses are applied to examine these segments’ forest value orientations, sociodemographic features, and service demands. The Acceptance group tends to be potential ecotourists, while still recognizing the commercial value of the natural resources. The Conditionality group may not possess a strong sense of ecotourism, given that its favored services can affect the environment. Overall, this article confirms the use of multidimensional environmental value orientation approaches can generate a comprehensive natural tourist segment comparison that benefits practical management decision making.

  20. Comparing different approach and avoidance models of learning and personality in the prediction of work, university, and leadership outcomes.

    Science.gov (United States)

    Jackson, Chris J; Hobman, Elizabeth V; Jimmieson, Nerina L; Martin, Robin

    2009-05-01

    Jackson (2005) developed a hybrid model of personality and learning, known as the learning styles profiler (LSP) which was designed to span biological, socio-cognitive, and experiential research foci of personality and learning research. The hybrid model argues that functional and dysfunctional learning outcomes can be best understood in terms of how cognitions and experiences control, discipline, and re-express the biologically based scale of sensation-seeking. In two studies with part-time workers undertaking tertiary education (N = 137 and 58), established models of approach and avoidance from each of the three different research foci were compared with Jackson's hybrid model in their predictiveness of leadership, work, and university outcomes using self-report and supervisor ratings. Results showed that the hybrid model was generally optimal and, as hypothesized, that goal orientation was a mediator of sensation-seeking on outcomes (work performance, university performance, leader behaviours, and counterproductive work behaviour). Our studies suggest that the hybrid model has considerable promise as a predictor of work and educational outcomes as well as dysfunctional outcomes.

  1. A Petri net-based approach for supporting aspect-oriented modeling

    Lianwei GUAN; Xingyu LI; Hao HU; Jian LU

    2008-01-01

    The concept of aspect-orientation allows for modularizing crosscutting concerns as aspect modules. Aspect-orientation originally emerged at the program-ming level, and has stretched over other development phases now. Among them aspect-oriented modeling (AOM) is a hot topic, and there are many approaches supporting it. Petri net is a good formalism which can provide the foundations for modeling software and simulating its execution, but fails to resolve the prob-lem of crosscutting concerns to support AOM. So, this paper presents an approach which extends the Petri net so as to support the AOM. In this paper, the basic functions of the system are modeled as base net by Petri net, and the crosscutting concerns are modeled as aspect nets. In order to analyze the whole system, woven mechanism is proposed to compose the aspect nets and base net together. The problems about aspect-aspect conflict and conflict relations may exist among the aspect nets matching the shared join point, thus this paper propose solutions to resolve them. The Object Petri net which is an extension of traditional Petri net is also extended so as to support aspect-oriented mod-eling here.

  2. From the ephemeral to the enduring: how approach-oriented mindsets lead to greater status.

    Science.gov (United States)

    Kilduff, Gavin J; Galinsky, Adam D

    2013-11-01

    We propose that the psychological states individuals bring into newly formed groups can produce meaningful differences in status attainment. Three experiments explored whether experimentally created approach-oriented mindsets affected status attainment in groups, both immediately and over time. We predicted that approach-oriented states would lead to greater status attainment by increasing proactive behavior. Furthermore, we hypothesized that these status gains would persist longitudinally, days after the original mindsets had dissipated, due to the self-reinforcing behavioral cycles the approach-oriented states initiated. In Experiment 1, individuals primed with a promotion focus achieved higher status in their newly formed groups, and this was mediated by proactive behavior as rated by themselves and their teammates. Experiment 2 was a longitudinal experiment and revealed that individuals primed with power achieved higher status, both immediately following the prime and when the groups were reassembled 2 days later to work on new tasks. These effects were mediated by independent coders' ratings of proactive behavior during the first few minutes of group interaction. Experiment 3 was another longitudinal experiment and revealed that priming happiness led to greater status as well as greater acquisition of material resources. Importantly, these immediate and longitudinal effects were independent of the effects of a number of stable dispositional traits. Our results establish that approach-oriented psychological states affect status attainment, over and above the more stable characteristics emphasized in prior research, and provide the most direct test yet of the self-reinforcing nature of status hierarchies. These findings depict a dynamic view of status organization in which the same group may organize itself differently depending on members' incoming psychological states. PMID:23895266

  4. A service-oriented approach for flexible process support within enterprises: application on PLM systems

    Hachani, Safa; Gzara, Lilia; Verjus, Hervé

    2013-02-01

    Manufacturing industries collaborating to develop new products need to implement an effective management of their design processes (DPs) and product information. Unfortunately, product lifecycle management (PLM) systems which are dedicated to support design activities are not efficient as it might be expected. Indeed, DPs are changing, emergent and non deterministic, due to the business environment under which they are carried out. PLM systems are currently based on workflow technology which does not support process agility. So, needs in terms of process support flexibility are necessary to facilitate the coupling with the environment reality. Furthermore, service-oriented approaches (SOA) enhances flexibility and adaptability of composed solutions. Systems based on SOA have the ability to inherently being evolvable. So, we can say that SOA can promote a support of flexible DPs. The aim of this work is to propose an alternative approach for flexible process support within PLM systems. The objective is to specify, design and implement business processes (BPs) in a very flexible way so that business changes can rapidly be considered in PLM solutions. Unlike existing approaches, the proposed one deal with a service-oriented perspectives rather than an activity-oriented one.

  5. 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

    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.

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

    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.

    An absolute prerequisite for the management of large investigating methods to build high-level monitoring computer networks is the ability to measure their systems that are built on top of existing monitoring performance. 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. Third, we try to map the former with the latter. APIs offered by the HP OpenView system.

    2013-03-01

    Full Text Available Rule-based methods have traditionally been applied to develop knowledge-based systems that replicate expert performance on a deep but narrow problem domain. 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.

    Siefert, Caleb J

    2012-12-01

    As part of their overall care, patients with borderline personality disorder may require inpatient hospitalization for containment and stabilization in the context of severe distress, increased risk for self-harm, or after self-harming acts. Though data suggests that such patients are frequently hospitalized, the benefits of brief hospitalizations can sometimes be questionable. In some cases, the hospitalization environment may increase patient distress. Additionally, frequent serial hospitalizations can disrupt or sidetrack longer-term outpatient treatments. The present paper presents a Goal-Oriented Limited-Duration Borderline Personality Disorder Inpatient Treatment approach. The approach integrates elements from many other expert-based approaches for working in brief hospital settings and centers on the creation of a preadmission treatment agreement with a planned discharge date. This agreement involves clear goals for treatment and specifies how staff will be involved. Establishing a discharge date early in treatment allows staff to immediately begin working with feelings of rejection or abandonment. At discharge, recommendations are made and criteria for future admissions are set forth. This paper provides a description of the approach, information to consider in determining appropriateness, discussion of methods for clarifying goals, review of the discharge planning approach, and several examples of clinician-patient exchanges. This paper concludes with a case example in which the approach was used and discussions of future directions and potential benefits and limitations of the approach. PMID:22181025

    Amaral, R; Alegre, H; Matos, J S

    2016-01-01

    Many national and regional administrations are currently facing challenges to ensure long-term sustainability of urban water services, as infrastructures continue to accumulate alarming levels of deferred maintenance and rehabilitation. The infrastructure value index (IVI) has proven to be an effective tool to support long-term planning, in particular by facilitating the ability to communicate and to create awareness. It is given by the ratio between current value of an infrastructure and its replacement cost. Current value is commonly estimated according to an asset-oriented approach, which is based on the concept of useful life of individual components. The standard values assumed for the useful lives can vary significantly, which leads to valuations that are just as different. Furthermore, with water companies increasingly focused on the customer, effective service-centric asset management is essential now more than ever. This paper shows results of on-going research work, which aims to explore a service-oriented approach for assessing the IVI. The paper presents the fundamentals underlying this approach, discusses and compares results obtained from both perspectives and points to challenges that still need to be addressed. PMID:27438261

    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.

    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.

    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.

    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.

  14. Estimating Orientation Using Magnetic and Inertial Sensors and Different Sensor Fusion Approaches: Accuracy Assessment in Manual and Locomotion Tasks

    Elena Bergamini

    2014-10-01

    Full Text Available 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.

  19. 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.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    This paper proposes and illustrates an AI embedded object-oriented methodology to formulate the computable general equilibrium (CGE) models.In this framework,a CGE model is viewed as a collection of objects embedded AI or namely agents in computer world,corresponding to economic agents and entities in real world,such as government,households,markets and so on.A frame representation of major objects in CGE model is used for trade and environment.Embedded AI object-oriented approach(or software agent)is used in the CGE model representation can able to narrow the gap among the semantic representation,formal CGE (mathematical) representation and computer and algorithm representation,and to improve CGE in understanding and maintenance etc.In such a system,constructing a CGE model to appear an intuitive process rather than an abstract process.This intuitive process needs more understanding of the substance of economics and the logic underlying the problem rather than mathematical notation.

    Increasing the understanding of a proteome and how its protein composition is affected by for example different diseases, such as cancer, has the potential to improve strategies for early diagnosis and therapeutics. The Global Proteome Survey or GPS is a method that combines mass spectrometry and affinity enrichment with the use of antibodies. The technology enables profiling of complex proteomes in a species independent manner. The sensitivity of GPS, and other methods relying on affinity enrichment, is largely affected by the activity of the exploited affinity reagent. We here present an improvement of the GPS platform by utilizing an antibody immobilization approach which ensures a controlled immobilization process of the antibody to the magnetic bead support. More specifically, we make use of an antibody format that enables site-directed biotinylation and use this in combination with streptavidin coated magnetic beads. The performance of the expanded GPS platform was evaluated by profiling yeast proteome samples. We demonstrate that the oriented antibody immobilization strategy increases the ability of the GPS platform and results in larger fraction of functional antibodies. Additionally, we show that this new antibody format enabled in-solution capture, i.e. immobilization of the antibodies after sample incubation. A workflow has been established that permit the use of an oriented immobilization strategy for the GPS platform. PMID:26703809

    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.

    We have been witnessing a gradual and steady transformation from a pre dominantly rural society to an urban society in India and by 2030, it will have more people living in urban than rural areas. Slums formed an integral part of Indian urbanisation as most of the Indian cities lack in basic needs of an acceptable life. Many efforts are being taken to improve their conditions. To carry out slum renewal programs and monitor its implementation, slum settlements should be recorded to obtain an adequate spatial data base. This can be only achieved through the analysis of remote sensing data with very high spatial resolution. Regarding the occurrences of settlement areas in the remote sensing data pixel-based approach on a high resolution image is unable to represent the heterogeneity of complex urban environments. Hence there is a need for sophisticated method and data for slum analysis. An attempt has been made to detect and discriminate the slums of Pune city by describing typical characteristics of these settlements, by using eCognition software from quick bird data on the basis of object oriented approach. Based on multi resolution segmentation, initial objects were created and further depend on texture, geometry and contextual characteristics of the image objects, they were classified into slums and non-slums. The developed rule base allowed the description of knowledge about phenomena clearly and easily using fuzzy membership functions and the described knowledge stored in the classification rule base led to the best classification with more than 80% accuracy.

    For the last decades, GIS software technologies have made tremendous development and applied to many special fields when their targets are relevant to geographical locations. But the basis of cartographic mapping of GIS is a restriction for more development in GIS data modelling, storage and manipulation. Recently, much attention is being paid on ORDBMS(Object Relational Database Management System) to represent and manage GIS Data. New approaches have earned acceptance in many research communities and several proposals have emerged in commercial software for solving the management and manipulation on GIS vector data. Though the storage and management of field-based model data(e.g. raster, DEM, TIN) have got less achievement and people still use files and procedural ways to manipulation field-based GIS data in common applications. In this paper a new structure model using ORDBMS technology for field-based data's storage and management was proposed on the basis of full discussion on several GIS data management technologies, then a problem-oriented approach for DEM data management and manipulation was designed and implemented through open source software systems PostgreSQL and Python language. Experimental examples of different DEM data souces were stored, managed and used by using the extended spatial database system. The experiments illustrated that this solution would be a useful supplement to spatial database and it provided an effective way to DEM data management and analysis, and support the interoperability between vector data and field data.

    2010-05-01

    Melanocytic lesions show great morphological diversity in their architecture and the cytomorphological appearance of their composite cells. Whereas functional melanocytes show a dendritic cytomorphology and territorial isolation, lesional nevomelanocytes and melanoma cells typically show epithelioid, spindled or mixed cytomorphologies, and a range of architectural arrangements. Spindling is common to melanocytic lesions, and may either be a characteristic feature or a divergent appearance. The presence of spindle cells may mask the melanocytic nature of a lesion, and is often disconcerting, either due to its infrequent appearance in a particular lesion or its interpretation as a dedifferentiated phenotype. Spindle cell melanocytic lesions follow the full spectrum of potential biological outcomes, and difficulty may be experienced judging the nature of a lesion due to a lack of consistently reliable features to predict biological behaviour. Over time, recognition of numerous histomorphological features that may portend a more aggressive lesion have been identified; however, the translation of these features into a diagnostic entity requires a gestalt approach. Although most spindle cell melanocytic lesions may reliably be resolved through this standard approach, problem areas do exist for the surgical pathologist or dermatopathologist. With this review (part II of II), we complete our discussion of spindle cell melanocytic lesions, in order to: (1) model a systematic approach to such lesions; and (2) provide familiarity with those melanocytic lesions which either typically or occasionally display a spindled cytomorphology.

  15. Applicability of New Approaches of Sensor Orientation to Micro Aerial Vehicles

    Rehak, M.; Skaloud, J.

    2016-06-01

    This study highlights the benefits of precise aerial position and attitude control in the context of mapping with Micro Aerial Vehicles (MAVs). Accurate mapping with MAVs is gaining importance in applications such as corridor mapping, road and pipeline inspections or mapping of large areas with homogeneous surface structure, e.g. forests or agricultural fields. There, accurate aerial control plays a major role in successful terrain reconstruction and artifact-free ortophoto generation. The presented experiments focus on new approaches of aerial control. We confirm practically that the relative aerial position and attitude control can improve accuracy in difficult mapping scenarios. Indeed, the relative orientation method represents an attractive alternative in the context of MAVs for two reasons. First, the procedure is somewhat simplified, e.g. the angular misalignment, so called boresight, between the camera and the inertial measurement unit (IMU) does not have to be determined and, second, the effect of possible systematic errors in satellite positioning (e.g. due to multipath and/or incorrect recovery of differential carrier-phase ambiguities) is mitigated. First, we present a typical mapping project over an agricultural field and second, we perform a corridor road mapping. We evaluate the proposed methods in scenarios with and without automated image observations. We investigate a recently proposed concept where adjustment is performed using image observations limited to ground control and check points, so called fast aerial triangulation (Fast AT). In this context we show that accurate aerial control (absolute or relative) together with a few image observations can deliver accurate results comparable to classical aerial triangulation with thousands of image measurements. This procedure in turns reduces the demands on processing time and the requirements on the existence of surface texture. Finally, we compare the above mentioned procedures with direct sensor

  16. Automated detection of lunar craters based on object-oriented approach

    2008-01-01

    The object-oriented approach is a powerful method in making classification. With the segmentation of images to objects, many features can be calculated based on the objects so that the targets can be distinguished. However, this method has not been applied to lunar study. In this paper we attempt to apply this method to detecting lunar craters with promising results. Craters are the most obvious features on the moon and they are important for lunar geologic study. One of the important questions in lunar research is to estimate lunar surface ages by examination of crater density per unit area. Hence,proper detection of lunar craters is necessary. Manual crater identification is inefficient, and a more efficient and effective method is needed. This paper describes an object-oriented method to detect lunar craters using lunar reflectance images. In the method, many objects were first segmented from the image based on size, shape, color, and the weights to every layer. Then the feature of "contrast to neighbor objects" was selected to identify craters from the lunar image. In the next step, by merging the adjacent objects belonging to the same class, almost every crater can be taken as an independent object except several very big craters in the study area. To remove the crater rays diagnosed as craters,the feature of "length/width" was further used with suitable parameters to finish recognizing craters.Finally, the result was exported to ArcGIS for manual modification to those big craters and the number of craters was acquired.

    As noted previously, prior to permanently instituting an outcomes approach, we compared the effects of such a model to a nonoutcomes-managed approach. The positive trend noted during the study interval has been sustained 2 years later, and the variables of cost, LOS, and ventilator duration (median = 9 days for DRG 475, 483 combined) for these patients continue to be favorably affected (see Figure 2). In addition, the outcomes-management model has been well accepted by all members of the health care team. The outcomes manager is a respected and valued member of the team and is central to the ongoing success of the approach. Although the clinical pathway is an essential tool for focusing and delineating multidisciplinary best-practice, the pathway (and processes of care contained within) must be continually evaluated and changed as needed. The pathway cannot be static if care is to be progressive. Essential to the process is a method of collecting and processing data in a timely way. Further, it is important that data collection, while important, not be the focus of the role of outcomes manager. Instead, the focus is the delivery of timely and effective care. Our current outcomes model applies to management of patients beyond the boundaries of the MICU or pulmonary suite. In other words, once weaned and transferred to a regular floor the outcomes manager no longer manages the patients (although she does track selected outcomes). Management of patients throughout hospitalization is a future goal, but we are convinced that this cannot be accomplished by a single outcomes manager. Although we are aware that other outcomes models do follow patients throughout the continuum of hospitalization and beyond, our highly clinically interactive model precludes that possibility. We are currently considering other similar unit-based positions to provide the desired continuity following discharge from the MICU or pulmonary suite. Despite our enthusiasm for the outcomes

    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.

    2016-01-15

    To estimate causal effects of vaccine on post-infection outcomes, Hudgens and Halloran (2006) defined a post-infection causal vaccine efficacy estimand VEI based on the principal stratification framework. They also derived closed forms for the maximum likelihood estimators of the causal estimand under some assumptions. Extending their research, we propose a Bayesian approach to estimating the causal vaccine effects on binary post-infection outcomes. The identifiability of the causal vaccine effect VEI is discussed under different assumptions on selection bias. The performance of the proposed Bayesian method is compared with the maximum likelihood method through simulation studies and two case studies - a clinical trial of a rotavirus vaccine candidate and a field study of pertussis vaccination. For both case studies, the Bayesian approach provided similar inference as the frequentist analysis. However, simulation studies with small sample sizes suggest that the Bayesian approach provides smaller bias and shorter confidence interval length.

    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.

    Himberg, Henry; Motai, Yuichi; Bradley, Arthur

    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.

    Biro, Khalid; Sulieman, Hussein; Pradhan, Biswajeet; Buchroithner, Manfred

    Recently, object-oriented classification techniques based on image segmentation approaches are being actively studied in the high-resolution image processing tools to extract a variety of thematic information. Land use patterns in the semi-arid Sahel zone of Africa in Sudan is characterized by complex vegetation covers with scattered distribution of small and large agricultural fields. Therefore, image segmentation approach might not suitable due to the presence of these land cover variations. In this study, land use types in the African Sahel dry-lands were analysed using the object-oriented classification approach. TerraSAR-X data (X-band in HH and HV polarisation) with 3.0 m of spatial resolution was used for the land cover classification. Using a feature space optimization tool based on nearest neighbour classifier, the attributes of the TerraSAR-X image were optimized to obtain the best separability among the classes for the land use mapping. The results highlighted the importance of both TerraSAR-X and object-oriented classification approaches as a useful source of information and technique for land use analyses over drylands of African Sahel in Sudan.

    Full Text Available This work presents an architecture to help designing and deploying smart mobility applications. The proposed solution builds on the experience already matured by the authors in different fields: crowdsourcing and sensing done by users to gather data related to urban barriers and facilities, computation of personalized paths for users with special needs, and integration of open data provided by bus companies to identify the actual accessibility features and estimate the real arrival time of vehicles at stops. In terms of functionality, the first “monolithic” prototype fulfilled the goal of composing the aforementioned pieces of information to support citizens with reduced mobility (users with disabilities and/or elderly people in their urban movements. In this paper, we describe a service-oriented architecture that exploits the microservices orchestration paradigm to enable the creation of new services and to make the management of the various data sources easier and more effective. The proposed platform exposes standardized interfaces to access data, implements common services to manage metadata associated with them, such as trustworthiness and provenance, and provides an orchestration language to create complex services, naturally mapping their internal workflow to code. The manuscript demonstrates the effectiveness of the approach by means of some case studies.

    Clinical decision support (CDS) systems can support vaccine forecasting and immunization reminders; however, immunization decision-making requires data from fragmented, independent systems. Interoperability and accurate data exchange between immunization information systems (IIS) is an essential factor to utilize Immunization CDS systems. Service oriented architecture (SOA) and Health Level 7 (HL7) are dominant standards for web-based exchange of clinical information. We implemented a system based on SOA and HL7 v3 to support immunization CDS in Iran. We evaluated system performance by exchanging 1500 immunization records for roughly 400 infants between two IISs. System turnaround time is less than a minute for synchronous operation calls and the retrieved immunization history of infants were always identical in different systems. CDS generated reports were accordant to immunization guidelines and the calculations for next visit times were accurate. Interoperability is rare or nonexistent between IIS. Since inter-state data exchange is rare in United States, this approach could be a good prototype to achieve interoperability of immunization information. PMID:25954452

    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.

    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.

    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.

    Full Text Available To investigate, identify and specify environmental factors influencing sustainable and competitive development of industrial enterprises which are the driver of growth of national economies. External and internal environmental factors are considered in the context of innovation potentialities of companies-and innovations are the key factors which provide sustainable development of business structures. World practice of sustainable development in regard to industrial enterprises and modern theoretical and empirical concepts are investigated which tie-up sustainable development of industrial enterprises to their innovation activity. The result of this study is limited practice-oriented concept of complex character which allows to conclude that the level of innovation activity of an industrial enterprise directly depends on the level of its functioning and development. Practical use of the concept of interrelation of the level of development of industrial enterprises with due regard to above-mentioned restrictions is perspective in terms of formation of new tools considered as optimal limited alternative to current managerial approaches which mainly are response to external environmental changes, while modern business conditions demand pro-activity.

    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.

    Recent advancements in technology has led to the development of sophisticated software tools revitalizing growth in different domains. Taking advantage of this trend, urban energy domain have developed several compute intensive physical and data driven models. These models are used in various distinct simulation softwares to simulate the whole life-cycle of energy flow in cities from supply, distribution, conversion, storage and consumption. Since some simulation software target a specific energy system, it is necessary to integrate them to predict present and future urban energy needs. However, a key drawback is that, these tools are not compatible with each other as they use custom or propriety formats. Furthermore, they are designed as desktop applications and cannot be easily integrated with third-party tools (open source or commercial). Thereby, missing out on potential model functionalities which are required for sustainable urban energy management. In this paper, we propose a solution based on Service Oriented Architecture (SOA). Our approach relies on open interfaces to offer flexible integration of modelling and computational functionality as loosely coupled distributed services.

    Clinical decision support (CDS) systems can support vaccine forecasting and immunization reminders; however, immunization decision-making requires data from fragmented, independent systems. Interoperability and accurate data exchange between immunization information systems (IIS) is an essential factor to utilize Immunization CDS systems. Service oriented architecture (SOA) and Health Level 7 (HL7) are dominant standards for web-based exchange of clinical information. We implemented a system based on SOA and HL7 v3 to support immunization CDS in Iran. We evaluated system performance by exchanging 1500 immunization records for roughly 400 infants between two IISs. System turnaround time is less than a minute for synchronous operation calls and the retrieved immunization history of infants were always identical in different systems. CDS generated reports were accordant to immunization guidelines and the calculations for next visit times were accurate. Interoperability is rare or nonexistent between IIS. Since inter-state data exchange is rare in United States, this approach could be a good prototype to achieve interoperability of immunization information. PMID:25954452

    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.

  16. On Goal-Oriented, Hydrogeological Site Investigation: A Holistic Approach (Henry Darcy Medal Lecture)

    2016-04-01

    UQ (for Uncertainty Quantification) is a critical element of groundwater management and by extension, of hydrological site investigation. While it is clear that UQ is an important goal, there is ambiguity as to what the target of the UQ should be, and how to make UQ relevant in the context of public policy. Planning for UQ (meaning what measurements to take, where, how many, what frequency, etc.), one could consider environmental performance parameters (EPMs, such as concentrations or travel time) as the targets of site investigation. But there is a need to go beyond EPMs, and to consider the uncertainty related to impacts such as enhanced cancer-risk due to groundwater contamination or, more generally, to decisions facing regulators. In any case, UQ requires site investigation, and decision-makers, who end up paying for it, are not really interested in EPMs: they care about making operational decisions that are defensible legally and justified from the perspective of public good. The key to UQ, whether considering EPMS or operational decisions concerning the public good, is defining a suitable strategy for site investigation. There is a body of published works on relating site investigations with EPMs, but much less is known on how to support operational decisions with strategies for site characterization. In this lecture, I will address this issue and I will outline a comprehensive approach for addressing it using a statistical formalism that couples hypothesis testing with Bayesian statistics. I refer to this approach as goal-oriented site investigation. I will show how site investigation strategies, with specifics such as which measurements to take and where, could be related to goals lined with operational decisions. This includes (1) defining the relevant goals; (2) formulating hypotheses; (3) defining alternative strategies for site investigation and (4) evaluating them in terms of probabilities for making errors in accepting or rejecting the hypotheses.

  17. An Object Oriented Approach to Simulation of TRIGA Mark II Dynamic Response

    International Nuclear Information System (INIS)

    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

    Background The choice for the surgical approach of interdigital neuroma in the foot is controversial.Plantar approach can leave a painful scar on weight bearing area; hence, some prefer dorsal approach.The aim of the current study was to measure the outcome of interdigital (Morton's) neurectomy performed by a single surgeon using dorsal and plantar approaches.Methods A retrospective review of the patient records of one orthopaedic foot and ankle surgeon identified thirty-six patients (42 feet) who had been treated operatively for a primary, persistently painful interdigital neuroma.The mean follow-up was 18 months.Pain, weight bearing, wound problems and rehabilitation period were studied.Results The duration to full weight bearing, return to work, driving and recreational activities were at least one week shorter in the dorsal group.The overall satisfaction for surgery was rated as excellent or good in 85% of the thirty six patients.Scar problems were more troublesome and common in the plantar group.There was residual numbness noticed in twenty feet, the pattern of numbness was quite variable and it was bothersome in only seven feet.There was one recurrence in the plantar group.Conclusions Resection of a symptomatic interdigital neuroma through a dorsal or a plantar approach can result in a good outcome.Dorsal approach, however, is associated with better rehabilitation and less scar problems.

  20. Improving vascular access outcomes: a systems approach to eliminating structural barriers.

    Sands, Jeffrey J; Perry, Michael A

    2003-01-01

    Maximizing AV fistula creation, regular access monitoring, prompt outpatient interventions and minimizing catheter use are well-accepted approaches for vascular access management. Systemic barriers impede the application of these strategies. A misaligned reimbursement system coupled with educational deficits and a lack of accountability has contributed to the institutionalization of substandard vascular access care. The hallmark of performance management is to create systems in which incentives are aligned to produce desired behaviors. Realigning reimbursement through a combination of pre-ESRD funding, enhancements to the composite rate to reward outcomes and cover vascular access monitoring and updated reimbursement for outpatient vascular access procedures would improve care and decrease unnecessary hospitalizations. This should be coupled with clearly defined outcome standards and accountability incorporated into hospital accreditation and credentialing. Capitation may provide alternative solutions. A two-phased approach including reimbursement reform while exploring capitation represents a prudent course with the best likelihood of success. PMID:12596756

    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

    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%.

    The growing importance of oil spill detection as part of a rapid response system to oil pollution requires the ongoing development of algorithms. The aim of this study was to create a methodology for improving manual classification at the scale of entire water bodies, focusing on its repeatability. This paper took an object-oriented approach to radar image analysis and put particular emphasis on adaptation to the specificity of seas like the Baltic. Pre-processing using optimised filters enhanced the capability of a multilevel hierarchical segmentation, in order to detect spills of different sizes, forms and homogeneity, which occur as a result of shipping activities. Confirmed spills detected in ENVISAT/ASAR images were used to create a decision-tree procedure that classifies every distinct dark object visible in SAR images into one out of four categories, which reflect growing probability of the oil spill presence: look-alikes, dubious spots, blurred spots and potential oil spills. Our objective was to properly mark known spills on ASAR scenes and to reduce the number of false-positives by eliminating (classifying as background or look-alike) as many objects as possible from the vast initial number of objects appearing on full-scale images. A number of aspects were taken into account in the classification process. The method's performance was tested on a group of 26 oil spills recorded by HELCOM: 96.15% of them were successfully identified. The final target group was narrowed down to about 4% of dark objects extracted from ASAR images. Although a specialist is still needed to supervise the whole process of oil spill detection, this method gives an initial view, substantial for further evaluation of the scenes and risk estimation. It may significantly accelerate the pace of manual image analysis and enhance the objectivity of assessments, which are key aspects in operational monitoring systems.

  5. Valuing the contribution of knowledge-oriented workers to projects: a merit based approach in the construction industry

    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.

    There is general consensus in the research literature that market orientation is related to organizational performance. This study examines this relationship in the hospital industry. One unique feature of this study is that both market orientation and performance are conceptualized as being multi-dimensional constructs. Hence the technique of Structural Equations Modeling (SEM) is used to examine the relationship. Analyses were based on market orientation and performance data obtained from 175 hospitals in a five-state region of the United States. The SEM results confirm the multi-dimensional nature of both market orientation and performance, and the strong relationship between the constructs. Interestingly, this relationship is found to be much stronger for smaller hospitals than for larger hospitals. Implications for the hospital industry are discussed. PMID:10907326

Instead, several studies provide clear evidence in favor of the motivational orientation account that seems to operate independently of evaluative coding mechanisms. Implications for theoretical developments and future research designs are discussed.

  15. 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.

    Epilepsy surgery is effective in reducing both the number and frequency of seizures, particularly in temporal lobe epilepsy (TLE). Nevertheless, a significant proportion of these patients continue suffering seizures after surgery. Here we used a machine learning approach to predict the outcome of epilepsy surgery based on supervised classification data mining taking into account not only the common clinical variables, but also pathological and neuropsychological evaluations. We have generated models capable of predicting whether a patient with TLE secondary to hippocampal sclerosis will fully recover from epilepsy or not. The machine learning analysis revealed that outcome could be predicted with an estimated accuracy of almost 90% using some clinical and neuropsychological features. Importantly, not all the features were needed to perform the prediction; some of them proved to be irrelevant to the prognosis. Personality style was found to be one of the key features to predict the outcome. Although we examined relatively few cases, findings were verified across all data, showing that the machine learning approach described in the present study may be a powerful method. Since neuropsychological assessment of epileptic patients is a standard protocol in the pre-surgical evaluation, we propose to include these specific psychological tests and machine learning tools to improve the selection of candidates for epilepsy surgery.

    In cardiovascular (CV) diabetology a "one-size fitsall"approach needs caution as vasculopathy and CVmanifestations in patients with type 2 diabetes (T2D)with short disease duration are different as comparedto those with longer duration. This is of relevance wheninterpreting results of CV outcome trials as responsesto any intervention aimed to reduce CV risk might bedifferent in patients with established vasculopathy ascompared to those without, where also the durationof the intervention may play a role. Additionally, themode-of-action of the intervention and its assumedtime to peak CV risk modulation need to be takeninto account an intervention with possibly immediateeffects, like on blood pressure or other direct functionaldynamic parameters such as endothelial function orrenal hemodynamics, could likely provide a meaningfulimpact on CV outcomes over a shorter time span thaninterventions that primarily target pathways that workon atherosclerotic processes, organ-remodelling, orvessel integrity. We are now faced with CV outcomeresults to interpret from a plethora of outcomes trials inT2D, some of which are testing the CV risk modulationpredominantly beyond glucose lowering, e.g. , as isthe case for several trials testing the newer therapyclasses di-peptidyl peptidase-4 inhibitors, glucagonlikeprotein-1 receptor analogues and sodium glucoseco-transporter-2 inhibitors, and this paper reviews thedata that support a call for a multiaxial approach tointerpret these results.

    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.

    Full Text Available Background: The poor outcome for patients with Wilms′ tumour (WT in developing countries has been predicated on late presentation, poverty and low rate of chemotherapeutic access. This study aims to evaluate the effects of an institutionalised approach to improving outcome for patients managed in a tertiary hospital in Nigeria. Materials and Methods: Oncology records of children diagnosed with WT between 2009 and 2013 were analysed for therapy completion and other prognostic parameters. Ensuing data were then compared with those from other centres in Africa. Results: Compared with results from some local and African studies, the therapy completion rate was higher (60% with a survival rate among this group being between 1 and 4 years. No patient was lost to follow-up because of unavailability or unaffordability of cytotoxic agents. Conclusion: This study shows that an institutionalised approach can help to improve access to anti-cancer drugs, reduce the rate of loss to follow-up and thus improve outcome. There is however need to improve on patient-doctor communication, form support groups and establish a WT registry.

  20. Machine learning approach for the outcome prediction of temporal lobe epilepsy surgery.

    Directory of Open Access Journals (Sweden)

    Rubén Armañanzas

    Full Text Available Epilepsy surgery is effective in reducing both the number and frequency of seizures, particularly in temporal lobe epilepsy (TLE. Nevertheless, a significant proportion of these patients continue suffering seizures after surgery. Here we used a machine learning approach to predict the outcome of epilepsy surgery based on supervised classification data mining taking into account not only the common clinical variables, but also pathological and neuropsychological evaluations. We have generated models capable of predicting whether a patient with TLE secondary to hippocampal sclerosis will fully recover from epilepsy or not. The machine learning analysis revealed that outcome could be predicted with an estimated accuracy of almost 90% using some clinical and neuropsychological features. Importantly, not all the features were needed to perform the prediction; some of them proved to be irrelevant to the prognosis. Personality style was found to be one of the key features to predict the outcome. Although we examined relatively few cases, findings were verified across all data, showing that the machine learning approach described in the present study may be a powerful method. Since neuropsychological assessment of epileptic patients is a standard protocol in the pre-surgical evaluation, we propose to include these specific psychological tests and machine learning tools to improve the selection of candidates for epilepsy surgery.

    Numerous studies have demonstrated how temperature can affect perceptual, cognitive and psychomotor performance (e.g. Hancock, P.A., Ross, J., and Szalma, J., 2007. A meta-analysis of performance response under thermal stressors. Human Factors: The Journal of the Human Factors and Ergonomics Society, 49 (5), 851-877). We extend this research to interpersonal aspects of performance, namely service employees' and salespeople's customer orientation. We combine ergonomics with recent research on social cognition linking physical with interpersonal warmth/coldness. In Experiment 1, a scenario study in the lab, we demonstrate that student participants in rooms with a low temperature showed more customer-oriented behaviour and gave higher customer discounts than participants in rooms with a high temperature - even in zones of thermal comfort. In Experiment 2, we show the existence of alternative possibilities to evoke positive temperature effects on customer orientation in a sample of 126 service and sales employees using a semantic priming procedure. Overall, our results confirm the existence of temperature effects on customer orientation. Furthermore, important implications for services, retail and other settings of interpersonal interactions are discussed. Practitioner Summary: Temperature effects on performance have emerged as a vital research topic. Owing to services' increasing economic importance, we transferred this research to the construct of customer orientation, focusing on performance in service and retail settings. The demonstrated temperature effects are transferable to services, retail and other settings of interpersonal interactions. PMID:22455315

    Melaka Manipal Medical College (Manipal Campus; Manipal, Karnataka, India) conducts the Bachelor of Medicine and Bachelor of Surgery program, for which the admission intakes are during the months of March and September. The present study was undertaken to study the differences in learning approaches to physiology of undergraduate medical students in a partially problem-based learning (PBL)- and non-PBL-oriented curriculum. PBL was introduced as a curricular reform for the September 2006 batch of students (partially PBL group), whereas it was not incorporated for the March 2006 batch of students (non-PBL group). Learning approaches to physiology of both groups of students were compared using the short inventory of approaches to learning. Mean scores for deep and strategic approaches were found to be significantly higher for the partially PBL group compared with the non-PBL group. The results of the present study support the earlier observation that PBL promotes a deep approach to learning. PMID:18334566

    Managing scientific data is probably one the most challenging issue in modern science. The question is made even more sensitive with the need of preserving and managing high value fragile geological sam-ples: cores. Large international scientific programs, such as IODP or ICDP are leading an intense effort to solve this problem and propose detailed high standard work- and dataflows thorough core handling and curating. However most results derived from rather small-scale research programs in which data and sample management is generally managed only locally - when it is … The national excellence equipment program (Equipex) CLIMCOR aims at developing French facilities for coring and drilling investigations. It concerns indiscriminately ice, marine and continental samples. As part of this initiative, we initiated a reflexion about core curating and associated coring-data management. The aim of the project is to conserve all metadata from fieldwork in an integrated cyber-environment which will evolve toward laboratory-acquired data storage in a near future. In that aim, our demarche was conducted through an close relationship with field operators as well laboratory core curators in order to propose user-oriented solutions. The national core curating initiative currently proposes a single web portal in which all scientifics teams can store their field data. For legacy samples, this will requires the establishment of a dedicated core lists with associated metadata. For forthcoming samples, we propose a mobile application, under Android environment to capture technical and scientific metadata on the field. This application is linked with a unique coring tools library and is adapted to most coring devices (gravity, drilling, percussion, etc...) including multiple sections and holes coring operations. Those field data can be uploaded automatically to the national portal, but also referenced through international standards or persistent identifiers (IGSN, ORCID and INSPIRE

  9. Current status and perspectives of neurobehavioral approaches in guideline—oriented animal testing

    2002-01-01

    This presentation aims to overview the current status and perspective of behavioral approaches used in guideline-oriented toxicological studies for agricultural chemicals.Guidelines revised recently (MAFF,OECD,EPA) require sytematic observation of non-learning behavior using defined scales.The observational endpoints are organized into a battery (e.g.functional observational battery,FOB) and inculde home-cage and open-field observation of behavior reactivity to various stimuli(e.g.auditory,tactile,visual),grip strength,and motor activity under a novel environment.The outline of FOB will be illustrated and discussed in the first half of the presentation.One social concern in neurotoxicology is the impact of chemical exposure on cnognitive functions such as learning and memory as well as non-learning behavior.Guidelines describe the necessity of learning and memory tests when other data suggest potential effects on brain function,even though little information regarding cognitive status other than brain pathology can be obtained with FOB.This discrepancy arises from the lack of a simple method compatible with regular studies.One candidate method is fear-induced freezing of rats conditioned to context and auditory cue(Kim & Fanselow,1992).In order to evaluate this paradigm as a screening method,the effects of trimethyltin chloride (TMT) have been studied.Prior to the study,it has been characterized that oral administration of TMT to rats produces excitatory clinical signs and massive neural cell death in the hippocampal CA1 and CA3 regions at lethal dose(8mg·kg-1),but not any abnormalities at sub-lethal doses (4mg·kg-1 or less).Oral administration of TMT at a sub-lethal dose produced a significant decrease in freezing time to the context (hippocampal-dependent measure),but not to the auditory cue.Administration of TMT at a sublethal dose significantly inhibited long-term potentiation in the CA1,but not in the dentate gyrus.These results suggest that the model can be

    2016-01-01

    Developmental theory and research have often focused on a single social identity category, for example, race or sexual orientation, and examined the consequences of that category on life outcomes. Yet intersectional models of social disadvantage (eg, Cole, 2009; Crenshaw, 1995; King, 1988) suggest that social categories combine to shape the experiences and life outcomes of individuals across life domains. In this chapter, we review empirical research that offers insight into the intersectionality of social identities across three critical developmental periods, namely, middle childhood, adolescence, and emerging adulthood. We also consider the consequences of intersecting identities across several life domains, including intergroup relations and political and civic engagement. Recognizing that the body of work on social identities is expansive, we focus our review on race/ethnicity, gender, sexual orientation, and immigrant status. In each developmental stage, we discuss what we know, drawing from the limited empirical literature, and offer suggestions on where we need to go moving forward. We conclude that research that focuses on as a single category and ignores the specific domain of development provides an incomplete and inaccurate picture that will hinder efforts to develop culturally appropriate and clinically effective prevention and intervention programs to meet the needs of our diverse children and youth living in the United States.

    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.

  14. An Approach to Assess Relative Degradation in Dissimilar Forests: Toward a Comparative Assessment of Institutional Outcomes

    Directory of Open Access Journals (Sweden)

    Krister P. Andersson

    2008-06-01

    Full Text Available A significant challenge in the assessment of forest management outcomes is the limited ability to compare forest conditions quantitatively across ecological zones. We propose an approach for comparing different forest types through the use of reference forests. We tested our idea by drawing a sample of 42 forests from the Midwest USA, Mexico, Guatemala, Honduras, Brazil, Bolivia, Uganda, and Nepal. We grouped these forests by shared characteristics and selected a reference forest to serve as a baseline for each forest type. We developed an index of disturbances using ratios of several forest measurements to assess differences between each study forest and its reference forest. None of the study forests was known to have been impacted by major natural disturbances during the past 50 years. Therefore, the disturbances in these forests appear to be largely related to human activities. The forests most similar to their reference forests have had limited human interventions. Our results indicate the potential of this approach to compare different forest conditions across biomes. We argue that development of this approach could facilitate analyses of forest management institutions, promote reliable indicators to compare management outcomes, and contribute to improved policies for conservation.

    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.

  18. Numerical approach of the injection molding process of fiber-reinforced composite with considering fiber orientation

    International Nuclear Information System (INIS)

    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 μ-CT. The simulation results showed a good agreement with experiment results

    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 μ-CT. The simulation results showed a good agreement with experiment results.

    2016-07-01

    Despite evidence-based psychotherapeutic treatment approaches such as cognitive behavioral therapy and psychodynamic therapy eating disorders still pose a challenge to therapists and patients alike. Eating disorders are associated with a high comorbid prevalence of personality disorders and other psychological axis-I-disorders, show highdrop-out rates and relapse rates and anorexia nervosa has the highest mortality rate compared to all psychiatric disorders. Even self-motivated patients frequently fail to achieve the treatment goals like developing a normal eating behavior, gaining weight, and changing the underlying dysfunctional behavioral patterns and cognitions. We will present a schematherapeutic approach with experiential methods, integrated in evidence-based CBT, with the intention to improve motivation and therapeutic outcome. PMID:27388869

    2015-01-01

    This case series presents clinical outcomes on reentry using regenerative submerged and nonsubmerged approaches in peri-implant defects; pre- and posttreatment assessments of nine implants in six patients are presented. A mean bone fill value of 91.3% with a 4.88-mm mean bone gain was obtained. Neither approach led to additional bone loss or required additional bone augmentation procedures. Strict methods of implant surface decontamination and detoxification were used on all patients, regardless of implant surface characteristics. The regenerative procedure was effective in the treatment of moderate to advanced peri-implantitis lesions without compromising the previous fixed implant-supported prostheses. These preliminary results are reasonably encouraging in that all cases showed bone gains. Nevertheless, caution must be exercised when determining reosseointegration, because it is not possible to ascertain it in clinical practice.

    A cell is the smallest functional unit of life. All forms of life rely on cellular processes to maintain normal functions, and changes in cell function induced by metabolic disturbances, physicochemical damage, infection, or abnormal gene expression may cause disease. To understand basic biology and to develop therapeutics for diseases, researchers need to study live cells. Along with advances in fluorescence microscopy and in vitro cell culture, live-cell imaging has become an essential tool in modern biology for the study of molecular and cellular events. Although researchers have often used fluorescent proteins to visualize cell-type-specific markers, this method requires genetic manipulations, which may not be appropriate in nontransgenic cells. Immunodetection of cellular markers requires the use of xenogenic antibodies, which may not detect intracellular markers in live cells. One option for overcoming these problems is the use of fluorescent small molecules targeted to specific cell types, which can enter live cells and interact with molecules of interest. We have used combinatorial chemistry to develop a large number of fluorescent small molecules as new imaging probes even without prior information about the probes' binding targets and mechanism, a strategy that we call the diversity oriented fluorescence library approach (DOFLA). We have used DOFLA to produce novel sensors and probes that detect a variety of biological and chemical molecules in vivo as well as in vitro. In this Account, we describe a series of fluorescent small molecules developed using DOFLA that bind specifically to particular cell types. These molecules provide new ways to detect and isolate these cells. The fluorescent probes CDy1, CDg4, and CDb8 tag embryonic stem cells and induced pluripotent stem cells but not fibroblasts or germ-line cells. CDr3 binds to an intracellular neural stem cell marker, fatty acid binding protein 7, which allows researchers to separate neural stem cells

    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.

Murphy Division, San Antonio, TX, USA Abstract: Chronic obstructive pulmonary disease (COPD is associated with significant morbidity, places substantial time and cost burden on the health care system, and is now the third leading cause of death in the US. Many interventions are available to appropriately manage patients with COPD; however, fully implementing these strategies to help improve outcomes may be difficult. Collaboration between an interprofessional team of health care professionals (which includes physicians, nurses, respiratory therapists, physical therapists, dietitians, pharmacists, and many others and COPD patients and caregivers is necessary to optimally manage these patients and to truly impact outcomes in this devastating disease. Prescribing evidence-based non-pharmacological and pharmacological therapies is an important start, but a true team-based approach is critical to successfully implement comprehensive care in patients with COPD. The goal of this review is to employ a case-based approach to provide practical information regarding the roles of the interprofessional team in implementing strategies to optimally manage COPD patients.

    U Pal; N Tripathy

    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.

    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

Business dynamics and technologicalinnovations have felt organizations to comply with adisparate mix of operating systems, applications anddatabases. This makes it difficult, time-consuming and costlyfor IT departments to deliver new applications that integrateheterogeneous technologies. It demands high interoperabilityand more flexible and adaptive business processmanagement. The inclination is to have systems assembled,from a loosely coupled collection of Web services, which areuniversal and integrated. This technical area appears tohave scope where the Agent Technology can be exploitedwith significant advantages. With Service OrientedArchitecture a decomposable architecture, and associatedset of development and IT management disciplines,composed of loosely coupled services communicating viapre-established protocols, these services can be assembledad-hoc to form customized applications that address a widevariety of business requirements.In the present paper, we propose a conceptual frameworkfor agent-based Service Oriented Architecture (SOA. Inwhich we try to integrate Service Oriented Architecture withthe agent technology & other tactical technologies like webservices, business workflow services, Business meta-rules,search optimization of services and semantic Webtechnology for business service mappings.

    Patient education is a central component of patient-oriented medical rehabilitation. The aim of patient education is to provide patients with the fundamentals of acting as competent partners in the rehabilitation process. Thus, the goals of educational group programmes are compliance, self-management, and empowerment, which are aspired by means of providing information, training skills, and modifying attitudes. According to expert opinions, such programmes should comply with certain minimum criteria regarding aims, methods, and frameworks, which can then be complemented by additional quality criteria. Furthermore, educational programmes should meet all the substantial requirements and standards of the respective medical area and exhibit proven effectiveness. A nationwide survey of rehabilitation institutions has shown that the implementation of patient education does not meet the quality requirements in all cases, particularly regarding patient-oriented didactics, standardisation, manual-use and evaluation. An additional quality feature is marked by the skills and qualifications of the educators. Instructors should be competent in leading and moderating groups and using various methods and media in order to fulfill the standards of modern educational concepts. As ample evidence has shown, patient participation and improved self-efficacy are indispensable when trying to promote healthy lifestyles in patients. Additional opportunities for enhancing patient orientation and optimizing patient education are provided by measures of behavioural planning and after-care as attempts to convey the behavioural changes in the patients' everyday lives.

Instructors should be competent in leading and moderating groups and using various methods and media in order to fulfill the standards of modern educational concepts. As ample evidence has shown, patient participation and improved self-efficacy are indispensable when trying to promote healthy lifestyles in patients. Additional opportunities for enhancing patient orientation and optimizing patient education are provided by measures of behavioural planning and after-care as attempts to convey the behavioural changes in the patients' everyday lives.

    Two experiments investigated the conditions under which majority and minority sources instigate systematic processing of their messages. Both experiments crossed source status (majority vs. minority) with message quality (strong vs. weak arguments). In each experiment, message elaboration was manipulated by varying either motivational (outcome relevance, Experiment 1) or cognitive (orientating tasks, Experiment 2) factors. The results showed that when either motivational or cognitive factors encouraged low message elaboration, there was heuristic acceptance of the majority position without detailed message processing. When the level of message elaboration was intermediate, there was message processing only for the minority source. Finally, when message elaboration was high, there was message processing for both source conditions. These results show that majority and minority influence is sensitive to motivational and cognitive factors that constrain or enhance message elaboration and that both sources can lead to systematic processing under specific circumstances.

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

    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.

  18. Operationalising the capability approach for outcome measurement in mental health research.

    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

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

    Directory of Open Access Journals (Sweden)

    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

    2011-01-01

    Purpose To test the hypothesis that posterior approach ptosis surgery, with or without blepharoplasty, can improve the cosmetic appearance of the eyelid. Methods In a retrospective, observational, consecutive case cohort study, 261 patients who had posterior approach upper eyelid ptosis surgery with or without concurrent blepharoplasty performed by one surgeon, between 1997 and 2009, were reviewed. Patients were included if they had symmetric eyelid position within 1.5 mm at 3 months after surgery. Outcome measures were subjective grading of eyelid margin contour, millimeters of tarsal platform show (TPS), and millimeters of eyebrow fat span (BFS). Paired preoperative and postoperative standardized photographs were viewed in masked fashion by three experts. Results One hundred and forty patients (55 men, 85 women, mean age 70 years, range 20–93) who underwent 233 posterior approach procedures for correction of upper eyelid ptosis had postoperative eyelid symmetry within 1.5 mm. Concurrent blepharoplasty was performed in 67 cases. Eyelid contour scores were significantly improved following surgery (P=.009). Ptosis surgery, without blepharoplasty, decreased the TPS, from 6.1±2.5 mm to 4.8±2.0 mm (P<.001). Patients who underwent concurrent blepharoplasty had a statistically insignificant increase of TPS from 4.0±3.5 mm to 4.3±3.6 mm, had a decrease of BFS from 20.8±6.3 mm to 17.7±6.4 mm (P=.001), and showed similar BFS symmetry postoperatively, compared to patients who had ptosis surgery only. Conclusions Posterior approach surgery alone was often successful in controlling TPS: it shortened the TPS. Blepharoplasty combined with posterior approach ptosis surgery tended to lengthen the TPS and shorten the BFS. PMID:22253486

    Biaxially oriented polypropylene (BOPP) film is one of the most popularly used materials for the gravure printing process in flexible packaging industry. The skin layers of BOPP film were associated with 3-6 weight % of propylene-ethylene copolymer. These films were completely biaxial-oriented by sequential stretching process after which the film surfaces were subjected to corona treatment integrated in the production line. The FT-IR results exhibited that polar functional groups as carbonyl molecules were established on the corona-treated BOPP film. The contact angles of these BOPP films were measured; the surface free energies (SFE) were then calculated. AFM topographical images also agreed well with the SFE which increased as the contents of propylene-ethylene copolymer increased. An approximated 20% increased SFE was obtained for the BOPP film that was associated with 6% propylene-ethylene copolymer. The printing quality on BOPP films was tested by light microscope which confirmed that the chromatic resolution of the printed images improved down to even more smaller groove sizes, 10 or 5 dot%. This improvement was also examined and found to correspond well with the interfacial tensions and work of adhesion between the inks and the modified BOPP films.

  2. 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.

  4. 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.

    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.

  9. Hybrid Approach for Language Identification Oriented to Multilingual Speech Recognition in the Basque Context

    Science.gov (United States)

    Barroso, N.; de Ipiña, K. López; Ezeiza, A.; Barroso, O.; Susperregi, U.

    The development of Multilingual Large Vocabulary Continuous Speech Recognition systems involves issues as: Language Identification, Acoustic-Phonetic Decoding, Language Modelling or the development of appropriated Language Resources. The interest on Multilingual Systems arouses because there are three official languages in the Basque Country (Basque, Spanish, and French), and there is much linguistic interaction among them, even if Basque has very different roots than the other two languages. This paper describes the development of a Language Identification (LID) system oriented to robust Multilingual Speech Recognition for the Basque context. The work presents hybrid strategies for LID, based on the selection of system elements by Support Vector Machines and Multilayer Perceptron classifiers and stochastic methods for speech recognition tasks (Hidden Markov Models and n-grams).

  10. 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.

  11. 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.

    1999-04-01

    Results of qualitative biographical research on Christian fundamentalist converts and de-converts, and on occultist adolescents are presented and documented using case studies. Research focused on life themes and on biographical processes and transformations. Contrastive comparison of the cases resulted in typologies of Christian fundamentalist biographies and of "ways of dis-enchantment". These indicate that obligation to a tradition is no longer the model for religious socialization. Its competitors are biographical trajectories which can have the following characteristics: heresy is taken for granted, religious search is like an open life-style preference (accumulative heretic); ritual coping with life themes is predominant; and religious search follows the motive of sensation-seeking. A typology of religious styles is applied as an interpretive framework for (a) explaining the formation of fundamentalist orientations and (b) understanding development and transformation in religious biographies.

    Full Text Available This retrospective study compared the functional outcomes among stroke patients who had received rehabilitation based on different physiotherapy treatment approaches. The participants were divided into three groups according to the physiotherapist in charge of their treatment. The primary treatment approaches applied in Group A, Group B, and Group C were the functional approach, the Bobath approach, and the motor learning approach, respectively. For each participant, the Berg's Balance Scale score, the Modified Barthel Index, and the Modified Rivermead Mobility Index were compared among these three groups prior to and after the stroke rehabilitation programme. Within-group analysis showed that Group A, Group B, and Group C participants had a statistically significant improvement in their Modified Barthel Index (p  0.05. In summary, this study showed that different combinations of treatment approaches may induce similar improvement in functional outcomes after stroke rehabilitation.

    Background Older adults experiencing multiple chronic illnesses are at high risk of hospitalization and health decline if they are unable to manage the significant challenges posed by their health conditions. Goal-oriented care approaches can provide better care for these complex patients, but clinicians find the process of ascertaining goals “too complex and too-time consuming,” and goals are often not agreed upon between complex patients and their providers. The electronic patient reported outcomes (ePRO) mobile app and portal offers an innovative approach to creating and monitoring goal-oriented patient-care plans to improve patient self-management and shared decision-making between patients and health care providers. The ePRO tool also supports proactive patient monitoring by the patient, caregiver(s), and health care provider. It was developed with and for older adults with complex care needs as a means to improve their quality of life. Objective Our proposed project will evaluate the use, effectiveness, and value for money of the ePRO tool in a 12-month multicenter, randomized controlled trial in Ontario; targeting individuals 65 or over with two or more chronic conditions that require frequent health care visits to manage their health conditions. Methods Intervention groups using the ePRO tool will be compared with control groups on measures of quality of life, patient experience, and cost-effectiveness. We will also evaluate the implementation of the tool. Results The proposed project presented in this paper will be funded through the Canadian Institute for Health Research (CIHR) eHealth Innovation Partnerships Program (eHIPP) program (CIHR–348362). The expected completion date of the study is November, 2019. Conclusions We anticipate our program of work will support improved quality of life and patient self-management, improved patient-centered primary care delivery, and will encourage the adoption of goal-oriented care approaches across primary

    We investigated the benefits of strategy-adaptation training for promoting transfer effects. This learner-oriented approach--which directly encourages the learner to generalize strategic behavior to new tasks--helps older adults appraise new tasks and adapt trained strategies to them. In Experiment 1, older adults in a strategy-adaptation training group used 2 strategies (imagery and sentence generation) while practicing 2 tasks (list and associative learning); they were then instructed on how to do a simple task analysis to help them adapt the trained strategies for 2 different unpracticed tasks (place learning and text learning) that were discussed during training. Two additional criterion tasks (name-face associative learning and grocery-list learning) were never mentioned during training. Two other groups were included: A strategy training group (who received strategy training and transfer instructions but not strategy-adaptation training) and a waiting-list control group. Both training procedures enhanced older adults' performance on the trained tasks and those tasks that were discussed during training, but transfer was greatest after strategy-adaptation training. Experiment 2 found that strategy-adaptation training conducted via a manual that older adults used at home also promoted transfer. These findings demonstrate the importance of adopting a learner-oriented approach to promote transfer of strategy training.

    2008-01-01

    Function performance specification (FPS) is one of the value management (VM) techniques de- veloped for the explicit statement of optimum product definition. This technique is widely used in software engineering and manufacturing industry, and proved to be successful to perform product defining tasks. This paper describes an FPS-odented approach for construction briefing, which is critical to the successful deliv- ery of construction projects. Three techniques, i.e., function analysis system technique, shared space, and computer-aided toolkit, are incorporated into the proposed approach. A computer-aided toolkit is developed to facilitate the implementation of FPS in the briefing processes. This approach can facilitate systematic, ef- ficient identification, clarification, and representation of client requirements in trail running. The limitations of the approach and future research work are also discussed at the end of the paper.

    2015-01-01

    Full Text Available 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.

    Full Text Available Perfectionism can influence how one approaches challenges and deals with setbacks, and, consequently, can inhibit or facilitate achievement. The present study (1 explored the relationship between Frost’s six dimensions of perfectionism and five types of coping strategies; (2 examined how dimensions of perfectionism predict coping in response to academic stress; and (3 investigated differences between gifted underachievers and other gifted students on perfectionism and coping among 130 American gifted students in grades 6–8. Results of stepwise regression models revealed approach coping was predicted by adaptive perfectionism (Positive Strivings-notably Organization, whereas avoidance coping (Internalizing, Externalizing, and Distancing was predicted by various combined models. Gifted underachievers displayed lower Positive Strivings perfectionism scores and lower positive coping when compared to achievers. This information is helpful when considering ways to guide gifted students to high levels of academic achievement while utilizing adaptive approaches.

    Full Text Available The transition from the classroom to clinical practice is stressful for many students. In the current situation in South Africawith the shortages of clinicians’ posts in hospitals, this transition is evenmore difficult given the reduced time that clinicians have for supervisingundergraduate students. The University of Stellenbosch initiated structured peer-led introduction to clinical education (SPLICE, duringwhich senior physiotherapy students orientate second year students toclinical practice.The aim of this study was to investigate the perceptions of all of thesecond, third and fourth year students who took part in these SPLICEsessions. This information was captured using a questionnaire with open and closed questions. The response of all of the students was extremely positive. Common to all cohorts of students was the opinion of themotivational benefits of the sessions as well as the opinion that their confidence increased. Students in the variousyears of study differed in the ways in which they felt more confident. Closely linked were those comments referring to a sense of increased preparedness for clinical practice and a positive learning environment. A positive change inattitude towards clinical practice was also noted in many second year students.Further research is needed into the effect that SPLICE might have had on the second year students when they enterclinical practice as third year students. The role and opinions of patients during these sessions, and indeed during anyclinical education sessions, including clinical examinations, needs further investigation.

    This article tested a contingency-oriented perspective to examine the dynamic relationships between in-the-moment borderline personality disorder (BPD) symptom events and in-the-moment triggers. An experience sampling study with 282 adults, including 77 participants with BPD, obtained reports of situational triggers and BPD symptom events five times daily for two weeks. Triggers included being rejected, betrayed, abandoned, offended, disappointed, having one’s self-concept threatened, being in a boring situation, and being alone. BPD was associated with increased situational triggers. Multilevel models revealed significant within-person associations between situational triggers and BPD symptoms for the average participant in the study, with significant individual variance in the strength and direction of trigger-symptom contingencies. Most trigger-symptom contingencies were stronger for individuals with higher borderline symptomatology, suggesting that triggers are meaningfully related to BPD. These findings highlight possible proximal mechanisms that maintain BPD and help explain the course of a disorder often described as chaotic and unpredictable. PMID:26200848

    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.

    Previous classification systems of chronic osteomyelitis have failed to provide objective and pragmatic guidelines for selection of the appropriate treatment strategy. In this study, we assessed the short-term treatment outcome in adult patients with long-bone chronic osteomyelitis prospectively where a modified host classification system was integrated with treatment strategy selection through a novel management algorithm. Twenty-six of the 28 enrolled patients were available for follow-up at a minimum of 12 months. The median patient age of was 36.5 years (range 18-72 years). Fourteen patients (54 %) were managed palliatively, and 11 patients (42 %) were managed through the implementation of a curative treatment strategy. One patient required alternative treatment in the form of an amputation. The overall success rate was 96.2 % (95 % CI 80.4-99.9 %) at a minimum of 12-months follow-up. Remission was achieved in all [11/11] patients treated curatively (one-sided 95 % CI 73.5-100.0 %). Palliative treatment was successful in 92.9 % [13/14] of cases (95 % CI 66.1-99.9 %).

  8. An integrative data mining approach to identifying adverse outcome pathway signatures.

    The Adverse Outcome Pathway (AOP) framework is a tool for making biological connections and summarizing key information across different levels of biological organization to connect biological perturbations at the molecular level to adverse outcomes for an individual or population. Computational approaches to explore and determine these connections can accelerate the assembly of AOPs. By leveraging the wealth of publicly available data covering chemical effects on biological systems, computationally-predicted AOPs (cpAOPs) were assembled via data mining of high-throughput screening (HTS) in vitro data, in vivo data and other disease phenotype information. Frequent Itemset Mining (FIM) was used to find associations between the gene targets of ToxCast HTS assays and disease data from Comparative Toxicogenomics Database (CTD) by using the chemicals as the common aggregators between datasets. The method was also used to map gene expression data to disease data from CTD. A cpAOP network was defined by considering genes and diseases as nodes and FIM associations as edges. This network contained 18,283 gene to disease associations for the ToxCast data and 110,253 for CTD gene expression. Two case studies show the value of the cpAOP network by extracting subnetworks focused either on fatty liver disease or the Aryl Hydrocarbon Receptor (AHR). The subnetwork surrounding fatty liver disease included many genes known to play a role in this disease. When querying the cpAOP network with the AHR gene, an interesting subnetwork including glaucoma was identified. While substantial literature exists to support the potential for AHR ligands to elicit glaucoma, it was not explicitly captured in the public annotation information in CTD. The subnetwork from this analysis suggests a cpAOP that includes changes in CYP1B1 expression, which has been previously established in the literature as a primary cause of glaucoma. These case studies highlight the value in integrating multiple data

    When conducting a meta-analysis of studies with bivariate binary outcomes, challenges arise when the within-study correlation and between-study heterogeneity should be taken into account. In this paper, we propose a marginal beta-binomial model for the meta-analysis of studies with binary outcomes. This model is based on the composite likelihood approach and has several attractive features compared with the existing models such as bivariate generalized linear mixed model (Chu and Cole, 2006) and Sarmanov beta-binomial model (Chen et al., 2012). The advantages of the proposed marginal model include modeling the probabilities in the original scale, not requiring any transformation of probabilities or any link function, having closed-form expression of likelihood function, and no constraints on the correlation parameter. More importantly, because the marginal beta-binomial model is only based on the marginal distributions, it does not suffer from potential misspecification of the joint distribution of bivariate study-specific probabilities. Such misspecification is difficult to detect and can lead to biased inference using currents methods. We compare the performance of the marginal beta-binomial model with the bivariate generalized linear mixed model and the Sarmanov beta-binomial model by simulation studies. Interestingly, the results show that the marginal beta-binomial model performs better than the Sarmanov beta-binomial model, whether or not the true model is Sarmanov beta-binomial, and the marginal beta-binomial model is more robust than the bivariate generalized linear mixed model under model misspecifications. Two meta-analyses of diagnostic accuracy studies and a meta-analysis of case-control studies are conducted for illustration.

    Impacted craters are commonly found on the surface of planets,satellites,asteroids and other solar system bodies.In order to speed up the rate of constructing the database of craters,it is important to develop crater detection algorithms.This paper presents a novel approach to automatically detect craters on planetary surfaces.The approach contains two parts:crater candidate region selection and crater detection.In the first part,crater candidate region selection is achieved by Kanade-Lucas-Tomasi (KLT) detector.Matrix-pattern-oriented least squares support vector machine (MatLSSVM),as the matrixization version of least square support vector machine (SVM),inherits the advantages of least squares support vector machine (LSSVM),reduces storage space greatly and reserves spatial redundancies within each image matrix compared with general LSSVM.The second part of the approach employs MatLSSVM to design classifier for crater detection.Experimental results on the dataset which comprises 160 preprocessed image patches from Google Mars demonstrate that the accuracy rate of crater detection can be up to 88%.In addition,the outstanding feature of the approach introduced in this paper is that it takes resized crater candidate region as input pattern directly to finish crater detection.The results of the last experiment demonstrate that MatLSSVM-based classifier can detect crater regions effectively on the basis of KLT-based crater candidate region selection.

    Full Text Available linguistic education means new opportunities for life and career: intercultural communication, writing scientific articles, taking part in conferences, reading special literature. However, adult learners getting additional linguistic education face some psychological and language barriers. The language difficulties are explained by the specific nature of the foreign language as a subject for learning. It is characterized by “limitlessness”, i.e. its volume has no limits, and it doesn’t give any specific information about the reality. The authors suggest some methods to remove the above mentioned barriers. One of such methods is selection of teaching materials based on student-centered approach to education. Student-centered approach means that students discuss their everyday life problems in social, professional, socio-cultural spheres. Such approach is especially important in teaching adults. For teaching materials in student-centered approach the authors use short stories that serve as a good “tool” for mastering a foreign language and bring an additional emotional component to the process of learning. Creating a friendly atmosphere at the lessons is also of particular importance.

    2015-12-01

    Extreme precipitation events cause natural disasters that impact many parts of the world. Understanding how these events vary in space and time is a key goal in climatology research. The recently developed CHRS CONNECT (Center for Hydrometeorology & Remote Sensing CONNected precipitation objECT) system is a global extreme precipitation event database derived from CHRS's satellite precipitation data products, including PERSIANN (Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks) and PERSIANN-CDR (Climate Data Record). Precipitation data from PERSIANN is hourly, 0.25ox0.25o grid, 60oS - 60oN, from 2000 to 2015, and data from PERSIANN-CDR is daily, 0.25ox0.25o grid, 60oS - 60oN, from 1983 to 2015. We used an advanced method in computer science which represents a data point on a three dimensional grid (longitude, latitude and time) called volumetric pixel or voxel. An object segmentation algorithm was developed to derive precipitation events as objects. In each object, voxels are connected to each other through the 26 connectivity faces (a voxel is connected to a neighboring voxel if they share a common face). The object-oriented algorithm was designed to provide a unique means in which extreme precipitation events and their attributes can be stored in a searchable database. This database is accessible through a user-friendly interface (connect.eng.uci.edu), allowing the user to retrieve events that fit specific criteria of interest such as spatiotemporal domain, maximum intensity, minimum duration and climatology indices. The interface includes several modes for visualization such as total precipitation, event tracking, and event evolution animation. The CHRS CONNECT tool is designed to be used for climatology research related to extreme precipitation events as well as for water resources management applications.

    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.

  4. 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

    Screening programs for congenital hypothyroidism (CH) dramatically improved the neuropsychological prognosis in affected children. However, mild impairments in cognitive performances, poorer motor skills, defective language abilities, and learning problems have been reported in some studies of early-treated CH children. The occurrence of these defects makes neuropsychological follow-up mandatory. The aim of the present study was to identify those neuropsychological functions that are more frequently affected in early-treated CH children and that might require prompt rehabilitation treatment to prevent permanent defects. The study group involved 24 CH children. Levothyroxine (LT4) treatment (initial dose 8-10 microg/kg per day) was started at mean age of 28 days (range 15-45) and was then adjusted with the goal to keep thyrotropin (TSH) and free thyroid hormone levels in the normal range. Cognitive evaluation was performed at 3, 5, and 7 years of age and did not significantly differ from that of controls. Mean neurological scores were lower in children 5 years of age than in controls. Children with severe neonatal hypothyroidism (serum thyroxine [T4] children and normal controls. The most affected functions were balance, extremity coordination, fine motricity, quality of movements, associated movements, and head movements. Language disorders were observed in half of CH children at 3 and 5 years of age, but moderately severe defects were restricted to those with severe neonatal hypothyroidism. In conclusion, a problem-oriented, simplified neuropsychological follow-up of early-treated children with CH should not systematically include the frequent repetition of time-consuming and expensive psychometric tests because individual IQ scores are in the normal range of tests in almost all CH children and can be differentiated from those of normal controls only on a population-statistic basis. Selected tests of motor proficiency are indicated at 3 and 5 years of age to

    2009-01-01

    One of the challenging problems in the multidatabase systems is to find the most viable solution to the problem of interoperability of distributed heterogeneous autonomous local component databases. This has resulted in the creation of a global schema over set of these local component database schemas to provide a uniform representation of local schemas. The aim of this paper is to use object oriented approach to integrate schemas of distributed heterogeneous autonomous local component database schemas into a global schema. The resulting global schema provides a uniform interface and high level of location transparency for retrieval of data from the local component databases. A set of integration operators are defined to integrate local schemas based on the semantic relevance of their classes and to provide a model independent representation of virtual classes of the global schema. The schematic representation and heterogeneity is also taken into account in the integration process. Justifications about Object...

    The Clinical Decision Support Consortium has completed two demonstration trials involving a web service for the execution of clinical decision support (CDS) rules in one or more electronic health record (EHR) systems. The initial trial ran in a local EHR at Partners HealthCare. A second EHR site, associated with Wishard Memorial Hospital, Indianapolis, IN, was added in the second trial. Data were gathered during each 6 month period and analyzed to assess performance, reliability, and response time in the form of means and standard deviations for all technical components of the service, including assembling and preparation of input data. The mean service call time for each period was just over 2 seconds. In this paper we report on the findings and analysis to date while describing the areas for further analysis and optimization as we continue to expand our use of a Services Oriented Architecture approach for CDS across multiple institutions.

    Evidence-based pharmacotherapy is a central aspect of optimal patient care for many chronic conditions. However, medication non-adherence frequently inhibits the attainment of optimal pharmacotherapy regimens. In this study, we designed, developed, and implemented a multifaceted clinical decision support (CDS) intervention that supports evidence-based pharmacotherapy and enhanced medication adherence through the use of a scalable, claims-driven, and service-oriented approach. The intervention includes a medication management report and a low adherence alert based on thirteen evidence-based pharmacotherapy rules for seven chronic conditions. Reports and alerts are delivered to primary care clinics and care managers that participate in a healthcare information exchange in North Carolina. The resulting system architecture may enable this CDS intervention to be widely disseminated to healthcare networks through an open-source model. PMID:21346956

    The growth and development of universities, just as other organizations, depend on their abilities to strategically plan and implement development blueprints which are in line with their vision and mission statements. The actualizations of these statements, which are often designed into goals and sub-goals and linked to their respective actors are better measured by defining key performance indicators (KPIs) of the university. The proposes ReGADaK, which is an extended the GRAnD approach highlights the facts, dimensions, attributes, measures and KPIs of the organization. The measures from the goal analysis of this unit serve as the basis of developing the related university's KPIs. The proposed data warehouse schema is evaluated through expert review, prototyping and usability evaluation. The findings from the evaluation processes suggest that the proposed data warehouse schema is suitable for monitoring the University's KPIs.

    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.

    Nees, Frauke; Heinrich, Angela; Flor, Herta

    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.

    2008-01-01

    In recent years,peer-to-peer (P2P) technologies are used for flexible and scalable information exchange in the Internet,but there exist problems to be solved for reliable information exchange.It is important to trace how data circulates between peers and how data modifications are performed during the circulation before reaching the destination for enhancing the reliability of exchanged information.However,such lineage tracing is not easy in current P2P networks,since data replications and modifications are performed independently by autonomous peers--this creates a lack of reliability among the records exchanged.In this paper,we propose a framework for traceable record exchange in a P2P network.By managing historical information in distributed peers,we make the modification and exchange histories of records traceable.One of the features of our work is that the database technologies are utilized for realizing the framework.Histories are maintained in a relational database in each peer,and tracing queries are written in the datalog query language and executed in a P2P network by cooperating peers.This paper describes the concept of the framework and overviews the approach to query processing.

    Full Text Available Software engineering requires modification of code during development and maintenance phase. During modification, a difficult task is to understand rationale of changed code. Present Integrated Development Environments (IDEs attempt to help this by providing features integrated with different types of repositories. However, these features still consume developer's time as he has to switch from editor to another window for this purpose. Moreover, these features focus on elements available in present version of code, thus increasing the difficulty of finding rationale of an element removed or modified earlier. Leveraging different sources for providing information through code completion menus has been shown to be valuable, even when compared to standalone counterparts offering similar functionalities in literature. Literature also shows that it is one of the most used features for consuming information within IDE. Based on that, we prepare an Eclipse plug-in and a framework that allows providing reason of code change, at method granularity, across versions through a new code completion menu in IDE. These allow a software engineer to gain insight about rationale of removed or modified methods which are otherwise not available in present version of code. Professional software engineers participated in our empirical evaluation process and we observed that more than 80% participants considered this to be a useful approach for saving time and effort to understand rationale of method change. Later, based on their feedback, the plug-in and framework is modified to incorporate chronological factors. We perform quasi experimental evaluation with professional software engineers. It is found that time required to find rationale of method change is reduced to at least half compared to usual amount of time required for all the software engineers who participated in the quantitative evaluation.

    2014-08-01

    Full Text Available The objectives of this research are to develop the variables which moderate the relationship between commitment and transportation services and to analyze the moderating effects of the variables. The conceptual and operational definitions of the variables were ascertained from prior research. The reliability and validity of collected data were tested by various methods and hypotheses are tested by a moderated regression analysis. The results are as follows. First, the moderating variables on the relationship between commitment and transportation services are identified as internal orientation and market orientation. The former has three sub-dimensions such as collaboration between departments, work standardization and process improving and the latter has three sub-dimensions such as intelligence generation, intelligence dissemination, and responsiveness. Second, work standardization is ascertained to enhance the relationship between commitment and trust. Third, process improving is verified as enhancing the relationship between commitment and trust. Fourth, work standardization is ascertained to enhance the relationship between commitment and flexibility. Fifth, intelligence generation is identified as enhancing the relationship between commitment and trust. Sixth, intelligence generation is verified as enhancing the relationship between commitment and flexibility. Therefore, forwarders can supply superior transportation services for customers when they achieve commitment and orientation such as work standardization, improvement of their service processes, and activities concerned with intelligence generation.

    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

  5. 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 routine use of genomic sequencing in clinical medicine has the potential to dramatically alter patient care and medical outcomes. To fully understand the psychosocial and behavioral impact of sequencing integration into clinical practice, it is imperative that we identify the factors that influence sequencing-related decision making and patient outcomes. In an effort to develop a collaborative and conceptually grounded approach to studying sequencing adoption, members of the National Human Genome Research Institute's Clinical Sequencing Exploratory Research Consortium formed the Outcomes and Measures Working Group. Here we highlight the priority areas of investigation and psychosocial and behavioral outcomes identified by the Working Group. We also review some of the anticipated challenges to measurement in social and behavioral research related to genomic sequencing; opportunities for instrument development; and the importance of qualitative, quantitative, and mixed-method approaches. This work represents the early, shared efforts of multiple research teams as we strive to understand individuals' experiences with genomic sequencing. The resulting body of knowledge will guide recommendations for the optimal use of sequencing in clinical practice.

  12. Sink-oriented Dynamic Location Service Protocol for Mobile Sinks with an Energy Efficient Grid-Based Approach

    Directory of Open Access Journals (Sweden)

    Hyunseung Choo

    2009-03-01

    Full Text Available Sensor nodes transmit the sensed information to the sink through wireless sensor networks (WSNs. They have limited power, computational capacities and memory. Portable wireless devices are increasing in popularity. Mechanisms that allow information to be efficiently obtained through mobile WSNs are of significant interest. However, a mobile sink introduces many challenges to data dissemination in large WSNs. For example, it is important to efficiently identify the locations of mobile sinks and disseminate information from multi-source nodes to the multi-mobile sinks. In particular, a stationary dissemination path may no longer be effective in mobile sink applications, due to sink mobility. In this paper, we propose a Sink-oriented Dynamic Location Service (SDLS approach to handle sink mobility. In SDLS, we propose an Eight-Direction Anchor (EDA system that acts as a location service server. EDA prevents intensive energy consumption at the border sensor nodes and thus provides energy balancing to all the sensor nodes. Then we propose a Location-based Shortest Relay (LSR that efficiently forwards (or relays data from a source node to a sink with minimal delay path. Our results demonstrate that SDLS not only provides an efficient and scalable location service, but also reduces the average data communication overhead in scenarios with multiple and moving sinks and sources.

  13. A Service-Oriented Approach for Dynamic Chaining of Virtual Network Functions over Multi-Provider Software-Defined Networks

    Directory of Open Access Journals (Sweden)

    Barbara Martini

    2016-06-01

    Full Text Available Emerging technologies such as Software-Defined Networks (SDN and Network Function Virtualization (NFV promise to address cost reduction and flexibility in network operation while enabling innovative network service delivery models. However, operational network service delivery solutions still need to be developed that actually exploit these technologies, especially at the multi-provider level. Indeed, the implementation of network functions as software running over a virtualized infrastructure and provisioned on a service basis let one envisage an ecosystem of network services that are dynamically and flexibly assembled by orchestrating Virtual Network Functions even across different provider domains, thereby coping with changeable user and service requirements and context conditions. In this paper we propose an approach that adopts Service-Oriented Architecture (SOA technology-agnostic architectural guidelines in the design of a solution for orchestrating and dynamically chaining Virtual Network Functions. We discuss how SOA, NFV, and SDN may complement each other in realizing dynamic network function chaining through service composition specification, service selection, service delivery, and placement tasks. Then, we describe the architecture of a SOA-inspired NFV orchestrator, which leverages SDN-based network control capabilities to address an effective delivery of elastic chains of Virtual Network Functions. Preliminary results of prototype implementation and testing activities are also presented. The benefits for Network Service Providers are also described that derive from the adaptive network service provisioning in a multi-provider environment through the orchestration of computing and networking services to provide end users with an enhanced service experience.

    Directory of Open Access Journals (Sweden)

    Jeffrey A Van Detta

    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.

    Thousands of refugees from around the world resettle in the United States every year. Many refugees suffer from mental health disorders as a result of experiences living in or escaping from their turbulent homelands, and many also experience mental health issues as they settle in their new host countries. As such, it is important to intervene during the early stages of refugee resettlement to help prevent or mitigate mental illness symptoms. However, because of several access and utilization barriers, such as stigma, refugees are not apt to receive needed mental health services. Moreover, the traditional Western model of treatment can be culturally incongruent with refugee practices. Alternative, culturally sensitive, community-based approaches must be considered. This article presents a community-oriented prevention and early intervention model that can be used with newly arrived refugees with limited English proficiency. Goals of the model are to increase knowledge of mental health and mental health service options to refugees, as well as support the process of adjusting to life in the United States. The New Refugee Services Project, developed by the Center for Survivors of Torture department of Asian Americans for Community Involvement (AACI) in San Santa Clara County, California is presented as an example case study. The structure outlined in this article aims to support the development, implementation, and assessment of future preventative interventions for refugee populations.

  16. A Customer-Oriented Approach to Satisfaction with Public Service Providers. Empirical Findings from a Market Undergoing Liberalization

    Directory of Open Access Journals (Sweden)

    Dan Cristian DABIJA

    2013-12-01

    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.

    Zhou, Yongjin; Zheng, Yong-Ping

    2011-04-01

    In this study, to complement our previously proposed method for estimating muscle fiber orientation, the Gabor filter bank (GF) technique was applied to sonograms of the biceps and forearm muscles to longitudinally enhance the coherently oriented and hyperechoic perimysiums regions. The method involved three steps: orientation field estimation, frequency map computation and Gabor filtering. The method was evaluated using a simulated image distorted with multiplicative speckle noises where the "muscles" were arranged in a bipennate fashion with an "aponeurosis" located in the middle. After enhancement using the GF approach, most of the original hyperechoic bands in the simulated image could be recovered. The proposed method was also tested using a group of biceps and forearm muscle sonograms collected from healthy adult subjects. Compared with the sonograms without enhancement, the enhanced images led to the detection of more linear patterns including muscle fascicles and smaller angle differences compared with the mean of manual results from two operators, therefore, were better prepared for the automatic estimation of muscle fiber orientation. The proposed method has the potential of assisting in the visualization of strongly oriented patterns in skeletal muscle sonograms as well as in the semi-automatic estimation of muscle fiber orientations.

    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.

      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

    "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.

  6. Learner differences and learning outcomes in an introductory biochemistry class: attitude toward images, visual cognitive skills, and learning approach.

    Milner, Rachel E

    2014-01-01

    The practice of using images in teaching is widespread, and in science education images are used so extensively that some have argued they are now the "main vehicle of communication" (C. Ferreira, A. Arroio Problems Educ. 21st Century 2009, 16, 48-53). Although this phenomenon is especially notable in the field of biochemistry, we know little about the role and importance of images in communicating concepts to students in the classroom. This study reports the development of a scale to assess students' attitude toward biochemical images, particularly their willingness and ability to use the images to support their learning. In addition, because it is argued that images are central in the communication of biochemical concepts, we investigated three "learner differences" which might impact learning outcomes in this kind of classroom environment: attitude toward images, visual cognitive skills, and learning approach. Overall, the students reported a positive attitude toward the images, the majority agreeing that they liked images and considered them useful. However, the participants also reported that verbal explanations were more important than images in helping them to understand the concepts. In keeping with this we found that there was no relationship between learning outcomes and the students' self-reported attitude toward images or visual cognitive skills. In contrast, learning outcomes were significantly correlated with the students' self-reported approach to learning. These findings suggest that images are not necessarily the main vehicle of communication in a biochemistry classroom and that verbal explanations and encouragement of a deep learning approach are important considerations in improving our pedagogical approach.

  7. Short-term outcomes of robotic radical esophagectomy for esophageal cancer by a nontransthoracic approach compared with conventional transthoracic surgery.

    Transthoracic esophagectomy (TTE) is believed to have advantages for mediastinal lymphadenectomy in the treatment of resectable esophageal cancer despite its association with a greater incidence of pulmonary complications and postoperative mortality. Transhiatal esophagectomy is regarded as less invasive, though insufficient in terms of lymph node dissection. With the aim of achieving lymph dissection equivalent to that of TTE, we have developed a nontransthoracic esophagectomy (NTTE) procedure combining a video-assisted cervical approach for the upper mediastinum and a robot-assisted transhiatal approach for the middle and lower mediastinum. We prospectively studied 22 accumulated cases of NTTE and verified feasibility by analyzing perioperative and histopathological outcomes. We compared this group's short-term outcomes with outcomes of 139 equivalent esophageal cancer cases operated on at our institution by conventional TTE (TTE group). In the NTTE group, there were no procedure-related events and no midway conversions to the conventional surgery; the mean operation time was longer (median, 524 vs. 428 minutes); estimated blood loss did not differ significantly between the two groups (median, 385 mL vs. 490 mL); in the NTTE group, the postoperative hospital stay was shorter (median, 18 days vs. 24 days). No postoperative pneumonia occurred in the NTTE group. The frequencies of other major postoperative complications did not differ significantly, nor were there differences in the numbers of harvested mediastinal lymph nodes (median, 30 vs. 29) or in other histopathology findings. NTTE offers a new radical procedure for resection of esophageal cancer combining a cervical video-assisted approach and a transhiatal robotic approach. Although further accumulation of surgical cases is needed to corroborate these results, NTTE promises better prevention of pulmonary complications in the management of esophageal cancer.

  10. Neurocognitive and Social Cognitive Approaches for Improving Functional Outcome in Early Psychosis: Theoretical Considerations and Current State of Evidence

    Cali F. Bartholomeusz

    2012-01-01

    Full Text Available Improving functional outcome, in addition to alleviating psychotic symptoms, is now a major treatment objective in schizophrenia research. Given the large body of evidence suggesting pharmacological treatments generally have minimal effects on indices of functioning, research has turned to psychosocial rehabilitation programs. Among these, neurocognitive and social cognitive interventions are at the forefront of this field and are argued to target core deficits inherent to the schizophrenia illness. However, to date, research trials have primarily focused on chronic schizophrenia populations, neglecting the early psychosis groups who are often as severely impaired in social and occupational functioning. This theoretical paper will outline the rationale for investigating adjunctive cognitive-based interventions in the early phases of psychotic illness, critically examine the current approach strategies used in these interventions, and assess the evidence supporting certain training programs for improving functional outcome in early psychosis. Potential pathways for future research will be discussed.

  12. Operative treatment via anterior approaches for cervicothoracic vertebrae tumors: surgical techniques and primary outcome

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Objective: To sum up 7 patients with cervicothoracic vertebrae tumors (C7 to T3) from March 1999 and May 2002, who underwent operative treatment via anterior approaches. Methods :The anterior approaches included low anterior cervical approach and high transthoracic approach. In 5 cases of segments of T1 and above involved, the low anterior cervical approaches were adopted, otherwise the high transthoracic approaches were used(2 cases). Excision of tumor was carried out according to demands of the Weinstein-Boriani-Biagini (WBB) staging system. Spine stability was reconstructed by bone autografting and instrumentation. There were 4 cases of primary tumor and 3 of metastases. Their mean age was 45.1 years (23 to 66). The mean follow up was 18.9 months (3 to 45). Results were evaluated by occurrence of complications, improvement of symptoms, local recurrence and mortality. Results: All patients stood surgery well. No significant complications occurred during and after operation. Local pain was significantly alleviated and neurological deficit was improved at least one Frankel grade. Three patients died.Local tumor control was obtained in 6 patients (85.7 %) until the end of follow-up. Conclusion:Our experience showed that via low anterior cervical approach and high transthoracic approach, the cervicothoracic vertebrae tumor could be excised safely and adequately. Moreover, excision of tumor according to the WBB surgical staging system and reconstruction of spine stability have made great contribution to local tumor control and the neurological function improvement.

  13. A win ratio approach to comparing continuous non-normal outcomes in clinical trials.

    2016-05-01

    Clinical trials are often designed to compare continuous non-normal outcomes. The conventional statistical method for such a comparison is a non-parametric Mann-Whitney test, which provides a P-value for testing the hypothesis that the distributions of both treatment groups are identical, but does not provide a simple and straightforward estimate of treatment effect. For that, Hodges and Lehmann proposed estimating the shift parameter between two populations and its confidence interval (CI). However, such a shift parameter does not have a straightforward interpretation, and its CI contains zero in some cases when Mann-Whitney test produces a significant result. To overcome the aforementioned problems, we introduce the use of the win ratio for analysing such data. Patients in the new and control treatment are formed into all possible pairs. For each pair, the new treatment patient is labelled a 'winner' or a 'loser' if it is known who had the more favourable outcome. The win ratio is the total number of winners divided by the total numbers of losers. A 95% CI for the win ratio can be obtained using the bootstrap method. Statistical properties of the win ratio statistic are investigated using two real trial data sets and six simulation studies. Results show that the win ratio method has about the same power as the Mann-Whitney method. We recommend the use of the win ratio method for estimating the treatment effect (and CI) and the Mann-Whitney method for calculating the P-value for comparing continuous non-Normal outcomes when the amount of tied pairs is small.

    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.

    Despite powerful evidence that informal social support contributes to survivors' safety and well-being, mainstream domestic violence (DV) programs have not developed comprehensive models for helping isolated survivors re-engage with these networks. Although many advocates use network-oriented strategies informally, they often do so without resources, funding, or training. This qualitative focus group study explored advocates' use and perceptions of network-oriented strategies. Advocates working in a range of DV programs across one state described the importance of network-oriented work and articulated its five dimensions, including helping survivors build their capacity to form healthy relationships, identify helpful and harmful network members, re-engage with existing networks, develop new relationships, and respond more effectively to network members.

    Gianotti, Simon; Hume, Patria A

    2007-12-01

    In New Zealand (NZ), the Accident Compensation Corporation (ACC) has developed a pre and post-implementation cost-outcome formulae for sport injury prevention to provide information regarding the success of a prevention programme. The ACC provides for the cost of all personal injuries in NZ and invests in prevention programmes to offset 1.6 million annual claims that cost $NZD 1.9 billion. The ACC invests in nine national community sport injury prevention programmes that represent 40% of sport claims and costs. Pre-implementation is used to determine the decision whether to invest in implementation and to determine the level of such investment for the injury prevention programme. Post-implementation is calculated two ways: unadjusted, assuming ceteris paribus; and adjusted assuming no prevention programme was in place. Post-implementation formulae provide a return on investment (ROI) for each dollar invested in the programme and cost-savings. The cost-outcome formulae approach allows ACC to manage expectations of the prevention programme as well as when it will provide a ROI, allowing it to take a long-term view for investment in sport injury prevention. Originally developed for its sport injury prevention programmes, the cost-outcome formulae have now been applied to the other prevention programmes ACC invests in such as home, road and workplace injury prevention.

    Full Text Available 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.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.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.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

    Ion-beam therapy provides advances in cancer treatment, offering the possibility of excellent dose localization and thus maximising cell-killing within the tumour. The full potential of such therapy can only be realised if the fundamental mechanisms leading to lethal cell damage under ion irradiation are well understood. The key question is whether it is possible to quantitatively predict macroscopic biological effects caused by ion radiation on the basis of physical and chemical effects related to the ion-medium interactions on a nanometre scale. We demonstrate that the phenomenon-based MultiScale Approach to the assessment of radiation damage with ions gives a positive answer to this question. We apply this approach to numerous experiments where survival curves were obtained for different cell lines and conditions. Contrary to other, in essence empirical methods for evaluation of macroscopic effects of ionising radiation, the MultiScale Approach predicts the biodamage based on the physical effects related to ionisation of the medium, transport of secondary particles, chemical interactions, thermo-mechanical pathways of biodamage, and heuristic biological criteria for cell survival. We anticipate this method to give great impetus to the practical improvement of ion-beam cancer therapy and the development of more efficient treatment protocols.

    One hundred thirty-seven total hip arthroplasty patients had a follow-up evaluation consisting of an orthopaedic physical evaluation, isokinetic strength testing, and collection of demographic and surgical information from medical records. The intraoperative variables of surgical time and blood loss and the functional outcome status of the subjects, as demonstrated by D'Aubigne--Postel ratings and isokinetic strength tests, were compared for various trochanteric management techniques: no osteotomy; complete Charnley-type osteotomy; sharp abductor release; and a wafer technique, in which a wafer of bone was osteotomized from the trochanter to release the abductors. A comparison of the mean values for the variables indicated that the wafer and sharp techniques were superior to the complete and no osteotomy techniques. The wafer technique resulted in statistically significant superior isokinetic strength measured in adduction, flexion, and extension. Surgical time was significantly greater in the complete osteotomy cases and blood loss was least in the wafer cases, although these differences were not significant. PMID:3183682

    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

    be the most promising method for mass production of low cost high temperature coated conductors. In order to reduce the decomposition time and improve the properties of YBCO films, copper propionate was used as the precursor and certain Lewis-bases were introduced into the precursor solution. The fluorine content of the solution was significantly reduced. High quality oriented YBCO films were prepared on LAO substrates with this low fluorine TFA-MOD approach. The effects of the sintering temperature on the oriented growth and properties of YBCO films were investigated. The preliminary results yielded the critical current density (Jc of 2 MA/cm2 and critical current (Ic of 120 A/cm width at 77 K and self-field.

    Introduction Non-communicable chronic diseases (NCCDs) represent a burden for public health. Alongside the established cardiometabolic risk factors such as high blood pressure and disorders of glucose and lipid metabolism, living habits and nutritional status at different stages of life are seen as contributors to this scenario. Gut microbiota composition and subclinical inflammation have been pointed out as underlying mechanisms of NCCDs. Studies involving health professionals have brought relevant contributions to the knowledge about risk factors. Technological advances facilitate data collection and analysis for big samples. A web-based survey addressed to collect data from a cohort study, which is able to identify NCCDs risk factors, is highly desirable. The objective of the Brazilian Nutritionists’ Health Study (NutriHS) is to gather online information on early life events, daily habits, emergent cardiometabolic risk factors and health outcomes of a specific subset of the Brazilian population. Methods and analysis NutriHS, developed at the School of Public Health—University of Sao Paulo, Brazil, is a research initiative that enrols undergraduates of nutrition courses from Brazilian universities and graduated volunteers. A web-based self-administered system was designed to collect health-related data. After fulfilling online questionnaires (socioeconomic, early life events and lifestyle data), participants are invited to a clinical visit for physical examination and laboratory procedures (blood sampling, faeces collection and body composition). At a 3-year interval, they will be invited to repeat similar procedures. Ethics and dissemination The NutriHS research protocol was approved by the Institutional Ethics Committee and is providing promising data which contribute to the understanding of pathophysiological links between early life events, body composition, gut microbiota, and inflammatory and metabolic risk profile.

    Background Diagnosis and treatment of diverticulitis in immunosuppressed patients are more challenging than in immunocompetent patients, as maintenance immunosuppressive therapies may mask symptoms or impair the patient’s ability to counteract the local and systemic infective sequelae of diverticulitis. The purpose of this study was to compare the in-hospital mortality and morbidity due to diverticulitis in immunosuppressed and immunocompetent patients and identify risk factors for lethal outcomes. Methods This retrospective study included consecutive in-patients who received treatment for colonic diverticulitis at our institution between April 2008 and April 2014. Patients were divided into immunocompetent and immunosuppressed groups. Primary end points were mortality and morbidity during treatment. Risk factors for death were evaluated. Results Of the 227 patients included, 15 (6.6%) were on immunosuppressive therapy for solid organ transplantation, autoimmune disease, or cerebral metastasis. Thirteen of them experienced colonic perforation and showed higher morbidity (p = 0.039). Immunosuppressed patients showed longer stays in hospital (27.6 v. 14.5 d, p = 0.016) and in the intensive care unit (9.8 v. 1.1 d, p 20 mg/dL, and immunosuppressive therapy were significant predictors of death. Age (hazard ratio [HR] 2.57, p = 0.008) and emergency operation (HR 3.03, p = 0.003) remained significant after multivariate analysis. Conclusion Morbidity and mortality due to sigmoid diverticulitis is significantly higher in immunosuppressed patients. Early diagnosis and treatment considering elective sigmoid resection for patients with former episodes of diverticulitis who are wait-listed for transplant is crucial to prevent death. PMID:27240131

    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

    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

  6. Acoustic metafluid with anisotropic mass density and tunable sound speed: An approach based on suspensions of orientable anisotropic particles

    Seitel, Mark; Tse, Stephen; Shan, Jerry

    2011-11-01

    We investigate liquid suspensions of micron-scale, anisotropic particles as potential acoustic metafluids having anisotropic and actively controllable acoustic properties. The effective mass density (and hence the sound propagation speed) of these metafluids can vary because the added mass of an anisotropic particle suspended in the fluid changes with the particle's orientation relative to the direction of the wave propagation. A suspension with disc-like particles oriented broadside to the direction of wave propagation is thus expected to have higher effective inertia and lower sound speed than a suspension with particles with end-on alignment. To test these predictions, sound speed is measured with a time-of-flight method in suspensions of micron-size nickel flakes suspended in oil, with and without magnetic-field-induced alignment of the particles. The sound speed, relative to the unaligned case, is found to decrease for particles oriented broadside to the sound wave, and increase for edgewise alignment. We also investigate the frequency dependence of the effective sound speed, since the added mass effect is expected to diminish as the flow becomes steady at low frequencies. The experimental results are compared to the predictions of a model proposed by Ahuja & Hardee (J. Acoust. Soc. Am 1978) for the acoustic properties of aligned oblate-spheroid suspensions.

    2009-12-15

    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

    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

    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.

  12. 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

    Appropriate management of patients with mechanical prosthetic valves on warfarin during dental procedures is crucial. If the patients continue warfarin, they might develop bleeding, while interruption of therapy can cause thromboembolic events. Bridging therapy (mostly heparin) is used in some patients, while others stop medications. There is no unifying protocol. Information on management of patients on warfarin undergoing dental procedures in Saudi Arabia is lacking. Therefore, the current study aimed to provide more insight into various approaches utilized by clinicians to deal with such patients at a large teaching hospital in Riyadh, and to evaluate the frequency and severity of bleeding and thromboembolic complications during different types of dental procedures in this population. This was a cohort study. Patient records were used to collect data on peri-procedural management of patients on warfarin, continuation or interruption of warfarin therapy, as well as bleeding and thromboembolic complications. Fifty medical records were reviewed from March to October 2012. Regarding management, 10% had no proper documentation, 74% underwent bridging therapy, 12% discontinued warfarin therapy, and 4% continued warfarin. Of the patients, 31% had minor bleeding (15% in patients on bridging therapy and 16% in patients continuing warfarin). Thromboembolic complications were documented in 4%, (2% in those on bridging therapy and 2% in those discontinuing warfarin). Patients on bridging therapy (heparin) were admitted to the hospital for a mean of five days, and none of the other patients were admitted. Adopting the protocol to continue warfarin caused bleeding tendency that was controlled with the usual measures, with more cost effectiveness, and no thromboembolic risks.

    The goal of every effort and actions/interventions in almost all healthcare settings throughout the world's health systems -primary care, inpatient, outpatient encounters, diagnostic and therapeutic interventions, peri-operative settings- is and has been to achieve a well defined outcome (a kind of improvement in health status of the patient under consideration, an observable and significant change(s) in selected set(s) of clinical parameters confirmed by laboratory results and pathology findings, improvements in clinical outcomes). Clinical inefficiencies, in this context, should be addressed very systematically and scientifically. This is achieved through a continuously monitoring approach to adverse drug events based on information repositories and evidence-based rule sets. For monitoring drug-related outcomes and clinical outcomes in general, the concept of DDD (Defined Daily Dose) compliance is explained in this article to eliminate and avoid adverse clinical outcomes.

    The research question addressed in this study was whether an increase in criminal thought process predicted elevated risk for recidivism in a community sample of offenders. Using a 1-year change on the General Criminal Thinking (GCT) score of the Psychological Inventory of Criminal Thinking Styles (PICTS) as the independent variable, time until first arrest following a second administration of the GCT as the dependent variable, and age, criminal history, race, and ethnicity as control variables, the effect of an elevated GCT score on subsequent recidivism was tested in 35,147 male and 5,254 female federal probationers and supervised releases. Separate analyses were conducted on male and female participants. The results revealed that a rise in GCT was an incrementally valid predictor of time until first arrest in both men and women after controlling for age, criminal history, and race/ethnicity (variable-oriented analysis) and predicted the presence of a subsequent arrest during a 1-year follow-up in men regardless of initial GCT score and in women with a low initial GCT score (person-oriented analysis). Although the effect sizes were, for the most part, small, they nonetheless demonstrated both clinical and statistical significance, thereby supporting the supposition that criminal thought process, as measured by the PICTS GCT score, is a dynamic risk factor.

    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. Convex Image Orientation from Relative Orientations

    Reich, M.; Heipke, C.

    2016-06-01

    In this paper we propose a novel workflow for the estimation of global image orientations given relative orientations between pairs of overlapping images. Our approach is convex and independent on initial values. First, global rotations are estimated in a relaxed semidefinite program (SDP) and refined in an iterative least squares adjustment in the tangent space of SO(3). A critical aspect is the handling of outliers in the relative orientations. We present a novel heuristic graph based approach for filtering the relative rotations that outperforms state-of-the-art robust rotation averaging algorithms. In a second part we make use of point-observations, tracked over a set of overlapping images and formulate a linear homogeneous system of equations to transfer the scale information between triplets of images, using estimated global rotations and relative translation directions. The final step consists of refining the orientation parameters in a robust bundle adjustment. The proposed approach handles outliers in the homologous points and relative orientations in every step of the processing chain. We demonstrate the robustness of the procedure on synthetic data. Moreover, the performance of our approach is illustrated on real world benchmark data.

    2016-02-01

    There is a need for research to understand and improve health systems for rare diseases in order to ensure that new, efficacious therapies developed through basic and early translational science lead to real benefits for patients. Such research must (i) focus on appropriate patient-oriented outcomes, (ii) include robust study designs that can accommodate real-world decision priorities, and (iii) involve effective stakeholder-engagement strategies. For transformative therapies, study outcomes will need to shift toward longer-term goals in recognition of success in preventing catastrophic outcomes. For incremental therapies, outcomes should be selected in recognition of the impact of care on quality of life for patients and families. To generate new evidence, we suggest that hybrid study designs integrating elements of practice-based observational research and pragmatic trials hold the most promise for addressing priorities such as minimizing bias, accounting for cointerventions, identifying long-term impacts, and considering clinical heterogeneity. To effectively engage with stakeholders, a knowledge exchange infrastructure is needed to foster collaboration among patients with rare diseases and their families, health-care providers, researchers, and policy decision makers. A key priority for these groups must be collaboration toward a shared understanding of the outcomes that are of most relevance to the facilitation of patient-centered care.

    The article describes the process of incorporating a set of learning outcomes into a geotechnical engineering course. The outcomes were developed using Bloom's taxonomy and define the knowledge, skills, and abilities the students are expected to achieve upon completion of the course. Each outcome begins with an action-oriented verb corresponding to one of six levels of achievement in the cognitive domain (remember, understand, apply, analyse, evaluate, and create). The article includes a listing of outcomes articulated for several course topics. The article also summarises how the outcomes were linked to lesson plans and assignments. Example formative and summative assessment methods and results are presented with the results of teaching evaluations, which indicate that students value this approach to course design. The article concludes with a discussion of how the above approach has been implemented in upper-division courses. Outcomes are presented for a course on earth retention systems.

    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.

A historic vilage is essentialy a setlement as wel as a kind of valuable cultural heritage. The literature review shows threats to these vilages are reflected in two aspects: the phenomenon of holowing vilages and the accelerated destruction from rural tourism development. The concept of heritage revitalization provides an access to solving these problems. This article put forward approach to revitalizing historic vilages oriented by tourism. Considering the background of tourism development in China, this paper put forward three characteristics of tourism-oriented revitalization of historic vilages, by introducing not only the concept but also some theories of heritage revitalization that is community-dominance, culture-growth and sustainability. To achieve the goal of tourism-oriented revitalization of historic vilages, the authors propose that boasting community pride, revitalizing tangible cultural heritage and revitalizing intangible cultural heritage are three components of it. Based on the literature review and analysis, we found commonalities between the philosophies of ecomuseum and tourism-oriented revitalization of historic vilages. Though possible problems remain to be solved, ecomuseum is an eficient path to take the theory of tourism-oriented revitalization of historic vilages into practice.

    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.

    Understanding the dynamic disease process is vital in early detection, diagnosis, and measuring progression. Continuous-time Markov chain (CTMC) methods have been used to estimate state-change intensities but challenges arise when stages are potentially misclassified. We present an analytical likelihood approach where the hidden state is modeled as a three-state CTMC model allowing for some observed states to be possibly misclassified. Covariate effects of the hidden process and misclassification probabilities of the hidden state are estimated without information from a 'gold standard' as comparison. Parameter estimates are obtained using a modified expectation-maximization (EM) algorithm, and identifiability of CTMC estimation is addressed. Simulation studies and an application studying Alzheimer's disease caregiver stress-levels are presented. The method was highly sensitive to detecting true misclassification and did not falsely identify error in the absence of misclassification. In conclusion, we have developed a robust longitudinal method for analyzing categorical outcome data when classification of disease severity stage is uncertain and the purpose is to study the process' transition behavior without a gold standard.

    2015-01-01

    Full Text Available Background: Posterior cervical decompression is an accepted treatment for multilevel cervical spondylotic myelopathy (CSM. Each posterior technique has its own advantages and disadvantages. In the present study, we compared the functional and radiological outcomes of expansive hemilaminectomy and laminoplasty with mini titanium plate in the treatment of multilevel CSM. Methods: Forty-four patients with multilevel CSM treated with posterior cervical surgery in Department of Orthopedic Surgery, Beijing Army General Hospital from March 2011 to June 2012 were enrolled in this retrospective study. Patients were divided into two groups by surgical procedure: Laminoplasty (Group L and hemilaminectomy (Group H. Perioperative parameters including age, sex, duration of symptoms, operative duration, and intraoperative blood loss were recorded and compared. Spinal canal area, calculated using AutoCAD ® software(Autodesk Inc., San Rafael, CA, USA, and neurological improvement, evaluated with Japanese Orthopedic Association score, were also compared. Results: Neurological improvement did not differ significantly between groups. Group H had a significantly shorter operative duration and significantly less blood loss. Mean expansion ratio was significantly greater in Group L (77.83 ± 6.41% than in Group H (62.72 ± 3.86% (P < 0.01. Conclusions: Both surgical approaches are safe and effective in treating multilevel CSM. Laminoplasty provides a greater degree of enlargement of the spinal canal, whereas expansive hemilaminectomy has the advantages of shorter operative duration and less intraoperative blood loss.

    This letter introduces an alternative approach to modeling the cardiovascular system with a short-term control mechanism published in Computers in Biology and Medicine, Vol. 47 (2014), pp. 104-112. We recommend using abstract components on a distinct physical level, separating the model into hydraulic components, subsystems of the cardiovascular system and individual subsystems of the control mechanism and scenario. We recommend utilizing an acausal modeling feature of Modelica language, which allows model variables to be expressed declaratively. Furthermore, the Modelica tool identifies which are the dependent and independent variables upon compilation. An example of our approach is introduced on several elementary components representing the hydraulic resistance to fluid flow and the elastic response of the vessel, among others. The introduced model implementation can be more reusable and understandable for the general scientific community.

    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

    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

    The so-called problem-oriented methods for organizing and recording clinical information offer many potential benefits to users in psychiatric institutions. Beyond the mechanical aspects of implementation, incorporating a problem-oriented approach into the practices of clinical teams entails conceptual and practical readjustments of considerable magnitude. Based on an 18-month study of eight psychiatric teams with diverse characteristics, the paper discusses rationales and priorities, as well as administrative and educational considerations in the conversion process. Such a process must be studied and understood in setting objectives and channeling resources, if outcomes are to match the expectations. PMID:1085344

    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.

    2013-01-01

    In the present discussion of sustainability centralised water infrastructures are exposed to new challenges, which may cause a conceptual alteration in urban water management. If technologies for closing urban water and nutrient cycles are to at least partially replace existing systems, then intensive reconstruction work becomes essential. The paper presents the development and implementation of a mathematical approach to minimise environmental impact and economic costs on the way to more source-controlled future states in urban water management. To find an optimal transformation strategy, a simultaneous project scheduling and network flow problem was defined as a bi-criteria mixed-integer program. An optimal solution is found by minimising two objective functions concurrently - the economic costs and 'ecologic costs' for the period of consideration. This paper discusses the influence of the weighting of these two costs on optimal transformation strategies for a real catchment in Germany. The results show that the approach can very well support decision makers when showing all impacts of transformation processes in detail. All in all, the developed model can be seen as a first step in strategy-finding for transformations in existing urban water systems.

    2016-08-01

    The continuous green T intersection is characterized by a channelized left-turn movement from the minor street approach onto the major street, along with a continuous through movement on the major street. The continuous flow through movement is not controlled by the three-phase traffic signal that is used to separate all other movements at the intersection. Rather, the continuous through movement typically has a green through arrow indicator to inform drivers that they do not have to stop. Past research has consistently shown that there are operational and environmental benefits to implementing this intersection form at three-leg locations, when compared to a conventional signalized intersection. These benefits include reduced delay, fuel consumption, and emissions. The safety effects of the conventional green T intersection are less clear. Past research has been limited to small sample sizes, or utilized only statistical comparisons reported crashes to evaluate the safety performance relative to similar intersection types. The present study overcomes past safety research evaluations by using a propensity scores-potential outcomes framework, with genetic matching, to compare the safety performance of the continuous green T to conventional signalized intersections, using treatment and comparison site data from Florida and South Carolina. The results show that the expected total, fatal and injury, and target crash (rear-end, angle, and sideswipe) frequencies are lower at the continuous green T intersection relative to the conventional signalized intersection (CMFs of 0.958 [95% CI=0.772-1.189], 0.846 [95% CI=0.651-1.099], and 0.920 [95% CI=0.714-1.185], respectively).

    Full Text Available We report on the design and implementation of ecological monitoring for an Australian biodiversity conservation incentive scheme - the Environmental Stewardship Program. The Program uses competitive auctions to contract individual land managers for up to 15 years to conserve matters of National Environmental Significance (with an initial priority on nationally threatened ecological communities. The ecological monitoring was explicitly aligned with the Program's policy objective and desired outcomes and was applied to the Program's initial Project which targeted the critically endangered White Box-Yellow Box-Blakely's Red Gum Grassy Woodland and Derived Native Grassland ecological community in south eastern Australia. These woodlands have been reduced to <3% of their original extent and persist mostly as small remnants of variable condition on private farmland. We established monitoring sites on 153 farms located over 172,232 sq km. On each farm we established a monitoring site within the woodland patch funded for management and, wherever possible, a matched control site. The monitoring has entailed gathering data on vegetation condition, reptiles and birds. We also gathered data on the costs of experimental design, site establishment, field survey, and data analysis. The costs of monitoring are approximately 8.5% of the Program's investment in the first four years and hence are in broad accord with the general rule of thumb that 5-10% of a program's funding should be invested in monitoring. Once initial monitoring and site benchmarking are completed we propose to implement a novel rotating sampling approach that will maintain scientific integrity while achieving an annual cost-efficiency of up to 23%. We discuss useful lessons relevant to other monitoring programs where there is a need to provide managers with reliable early evidence of program effectiveness and to demonstrate opportunities for cost-efficiencies.

  10. 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.

  13. Electronic structure, molecular orientation, charge transfer dynamics and solar cells performance in donor/acceptor copolymers and fullerene: Experimental and theoretical approaches

    International Nuclear Information System (INIS)

    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/cm2 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 π* 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.

    2016-02-01

    There is clear evidence across the globe that the clinical complexity of patients presenting to hospital with the syndrome of heart failure is increasing - not only in terms of the presence of concurrent disease states, but with additional socio-demographic risk factors that complicate treatment. Management strategies that treat heart failure as the main determinant of health outcomes ignores the multiple and complex issues that will inevitably erode the efficacy and efficiency of current heart failure management programmes. This complex problem (or conundrum) requires a different way of thinking around the complex interactions that underpin poor outcomes in heart failure. In this context, we present the COordinated NUrse-led inteNsified Disease management for continuity of caRe for mUltiMorbidity in Heart Failure (CONUNDRUM-HF) matrix that may well inform future research and models of care to achieve better health outcomes in this rapidly increasing patient population.

    Full Text Available Background and objective Video-assisted thoracoscopic surgery (VATS theoretically offers advantages over open thymectomy for clinically early-stage (Masaoka-Koga stage I and II thymic malignancies. However, longterm outcomes have not been well studied. We compared the postoperative outcomes and survival from a cohort study based on the database of the Chinese Alliance for Research in Thymomas (ChART. Methods Between 1994 and 2012, data of 1,117 patients having surgery for clinically early-stage (Masaoka-Koga stage I and II tumors were enrolled for the study. Among them, 241 cases underwent VATS thymectomy (VATS group, while 876 cases underwent open thymectomy (Open group. Univariate analyses were used to compare the clinical character and perioperative outcomes between the two groups. And multivariate analysis was performed to determine the independent predictive factors for long-term survival. Results Compared with the Open group, the VATS group had higher percentage of total thymectomy (80.5% vs 73.9%, P=0.028, resection rate (98.8% vs 88.7%, P<0.001 and less recurrence (2.9% vs 16.0%, P<0.001. Five-year overall survival was 92% after VATS and 92% after open thymectomy, with no significant difference between the two groups (P=0.15. However, 5-year disease free survival were 92% in VATS group and 83% in Open group (P=0.011. Cox proportional hazards model revealed that WHO classification, Masaoka-Koga stage and adjuvant therapy were independent predictive factors for overall survival, while surgical approach had no significant impact on long-term outcome. Conclusion This study suggests that VATS thymectomy is an effective approach for clinically early-stage thymic malignancies. And it may offer better perioperative outcomes, as well as equal oncological survival.

  6. Variations in the Quality of Care at Large Public Hospitals in Beijing, China: A Condition-Based Outcome Approach.

    Directory of Open Access Journals (Sweden)

    Ye Xu

    Full Text Available Public hospitals deliver over ninety percent of all outpatient and inpatient services in China. Their quality is graded into three levels (A, B, and C largely based on structural resources, but empirical evidence on the quality of process and outcome of care is extremely scarce. As expectations for quality care rise with higher living standards and cost of care, such evidence is urgently needed and vital to improve care and to inform future health reforms.We compiled and analyzed a multicenter database of over 4 million inpatient discharge summary records to provide a comprehensive assessment of the level and variations in clinical outcomes of hospitalization at 39 tertiary hospitals in Beijing. We assessed six outcome measures of clinical quality: in-hospital mortality rates (RSMR for AMI, stroke, pneumonia and CABG, post-procedural complication rate (RS-CR, and failure-to-rescue rate (RS-FTR. The measures were adjusted for pre-admission patient case-mix using indirect standardization method with hierarchical linear mixed models.We found good overall quality with large variations by hospital and condition (mean/range, in %: RSMR-AMI: 6.23 (2.37-14.48, RSMR-stroke: 4.18 (3.58-4.44, RSMR-pneumonia: 7.78 (7.20-8.59, RSMR-CABG: 1.93 (1.55-2.23, RS-CR: 11.38 (9.9-12.88, and RS-FTR: 6.41 (5.17-7.58. Hospital grade was not significantly associated with any risk-adjusted outcome measures.Going to a higher grade public hospital does not always lead to better patient outcome because hospital grade only contains information about hospital structural resources. A hospital report card with some outcome measures of quality would provide valuable information to patients in choosing providers, and for regulators to identify gaps in health care quality. Reducing the variations in clinical practice and patient outcome should be a focus for policy makers in the next round of health sector reforms in China.

    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

    2008-12-01

    Full Text Available Abstract Background Young people below the age of 18, whose lives are affected by looking after a relative with a disability or long-term illness, are called young carers. Evidence based family oriented support for young carers and their families in Germany is currently being developed. To allow for scientific evaluation, an outcome criterion needs to be chosen. Until today, there are no assessment instruments available, which focus on young carer's specific demands and needs. As HRQOL seems to be an adequate alternative outcome criterion, an integrative review of the literature was carried out to verify this assumption. Methods The aim of the integrative review was to get information about a the concept and the common definition of HRQOL in children, b preferable HRQOL assessment techniques in children, and c the relevance of HRQOL measures for the population of young carers. An additional aim of the review was to give advice on which instrument fits best to assess young carer's HRQOL in Germany. Searches were conducted in PubMed in order to obtain papers reporting about a the development or psychometric assessment of instruments measuring HRQOL in children and adolescents up to the age of 18, and b on the conceptual framework of HRQOL in children. Results HRQOL is a multidimensional construct covering physical, emotional, mental, social, and behavioural components of well-being and functioning as subjective perceived by a person depending on the cultural context and value system one is living in. Young carer's problems and needs are well covered by these common domains of HRQOL. Since no specific HRQOL-measures are available to address young carers, a generic one has to be chosen which a has been created for use in children, b allows self- and proxy-report, and c has good psychometric testing results. Comparing four generic measures with currently best published psychometric testing results, items of the KIDSCREEN cover young carer's specific

    In recent years there has been a tremendous need among healthcare professionals to assess the effectiveness, efficiency, and appropriateness of the patient care services being provided through criteria-based outcome and program evaluation. Although the need for a tool which could evaluate the effectiveness of patient care is widely recognized, such an undertaking has been severely limited due to the lack of any automated means to collect and analyze patient data on a routine, continuous basis within a clinical setting. We have developed and implemented at Mineral Springs Hospital, Banff, Alberta an integrated and automated hospital information system that not only continuously collects administrative, financial, and patient data, but also contains an intelligent component for automated outcome measure and program evaluation. The system collects various non-duplicated data elements from each routine work process within the facility on a continuous basis. Through the creation of a dynamic patient database, data is transformed into information--a powerful decision support tool. The system provides flexible user-defined reports in patient-specific resource utilization, direct and/or indirect specific financial costs, result reporting of each intervention, service provided and user-defined criteria-based outcome, and program evaluation. The system design incorporates expert rules, dynamic data entry forms, quantitative models, and user-defined access control. Using information derived from the dynamic common database, managers and front-line clinicians can easily evaluate and modify management decisions or careplans on a macro or micro level. An external review is planned to evaluate whether the system has helped the assessment of effectiveness, efficiency and appropriateness of healthcare services being provided at the hospital. The fundamental concept behind the system design is that the patient is the center of activity for data collection. The system provides the

    Community-Based Participatory Research is a research paradigm that encourages community participation in designing and implementing evaluation research, though the actual outcome measures usually reflect the "external" academic researchers' view of program effect and the policy-makers' needs for decision-making. This paper describes a replicable process by which existing standardized psychometric scales commonly used in youth-related intervention programs were modified to measure indicators of program success defined by community partners. This study utilizes a secondary analysis of data gathered in the context of a community-based youth violence prevention program. Data were retooled into new measures developed using items from the Alabama Parenting Questionnaire, the Hare Area Specific Self-Esteem Scale, and the Youth Asset Survey. These measures evaluated two community-defined outcome indicators, "More Parental Involvement" and "Showing Kids Love." Results showed that existing scale items can be re-organized to create measures of community-defined outcomes that are psychometrically reliable and valid. Results also show that the community definitions of parent or parenting caregivers exemplified by the two indicators are similar to how these constructs have been defined in previous research, but they are not synonymous. There are nuanced differences that are important and worthy of better understanding, in part through better measurement. PMID:23846829

    Purpose Obesity is associated with a number of medical comorbidities and is considered a risk factor for surgical complications. The purpose of this study was to analyze the influence of body habitus including obesity on the surgical outcomes of the Bilateral axillo-breast approach (BABA) robotic thyroidectomy (RoT) in papillary thyroid carcinoma (PTC) patients. Methods The medical records of 456 PTC patients who underwent BABA RoT between January 2011 and December 2012 were reviewed, and 310 women PTC patients who had undergone BABA robotic total thyroidectomy with central lymph node dissection were examined. Body habitus were evaluated by measuring body mass index (BMI), body surface area, and neck circumference. We divided the patients into BMI < 25 kg/m2 and BMI ≥ 25 kg/m2 groups. Clinicopathological data, surgical outcomes, and postoperative complications were evaluated. Results Clinicopathological characteristics did not differ between the 2 BMI groups. The creation of working space time (P = 0.210) and other surgical outcomes showed no significant differences between the groups. There were no statistically significant differences between body habitus indexes and postoperative length of hospital stay, number of retrieved central lymph nodes, postoperative thyroglobulin levels, occurrence of hypoparathyoidism, recurrent laryngeal nerve injury and wound complication. Conclusion Patient with large body habitus undergoing BABA RoT were not at an increased risk of surgical complications and showed good surgical outcomes. BABA RoT may be a good alternative operative method for PTC patients for whom cosmetic outcome is an important consideration.

    Full Text Available Arjun SinghDepartment of Pathology, Sri Venkateshwara Medical College Hospital and Research Centre, Pondicherry, IndiaPurpose: We use different methods to train our undergraduates. The patient-oriented problem-solving (POPS system is an innovative teaching–learning method that imparts knowledge, enhances intrinsic motivation, promotes self learning, encourages clinical reasoning, and develops long-lasting memory. The aim of this study was to develop POPS in teaching pathology, assess its effectiveness, and assess students’ preference for POPS over didactic lectures.Method: One hundred fifty second-year MBBS students were divided into two groups: A and B. Group A was taught by POPS while group B was taught by traditional lectures. Pre- and post-test numerical scores of both groups were evaluated and compared. Students then completed a self-structured feedback questionnaire for analysis.Results: The mean (SD difference in pre- and post-test scores of groups A and B was 15.98 (3.18 and 7.79 (2.52, respectively. The significance of the difference between scores of group A and group B teaching methods was 16.62 (P < 0.0001, as determined by the z-test. Improvement in post-test performance of group A was significantly greater than of group B, demonstrating the effectiveness of POPS. Students responded that POPS facilitates self-learning, helps in understanding topics, creates interest, and is a scientific approach to teaching. Feedback response on POPS was strong in 57.52% of students, moderate in 35.67%, and negative in only 6.81%, showing that 93.19% students favored POPS over simple lectures.Conclusion: It is not feasible to enforce the PBL method of teaching throughout the entire curriculum; However, POPS can be incorporated along with audiovisual aids to break the monotony of dialectic lectures and as alternative to PBL.Keywords: medical education, problem-solving exercise, problem-based learning

    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.
