  1. On the relations among work value orientations, psychological need satisfaction and job outcomes: A self-determination theory approach

    Vansteenkiste, Maarten; Neyrinck, Bart; Niemiec, Christopher P; Soenens, Bart; De Witte, Hans; Van den Broeck, Anja

    2007-01-01

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

    Full Text Available Justin Chew, Mei-Sian Chong, Yoke-Leng Fong, Laura Tay Department of Geriatric Medicine, Institute of Geriatrics and Active Ageing, Tan Tock Seng Hospital, Singapore, Singapore Background: Nonpharmacological interventions such as exercise and cognitive rehabilitation programs have shown promise in reducing the impact of dementia on the individual and the caregiver. In this study, we examine the effect of a multimodal cognitive and physical rehabilitation program for persons with mild dementia and their caregivers using conventional measures of cognition, behavior, quality of life (QoL, and caregiver burden together with goal attainment scaling (GAS, an individualized outcome measure.Methods: Goals were set at baseline, and GAS score was calculated at the end of the program. Participants were also assessed with the Chinese Mini-Mental State Examination, functional and behavioral scales (Barthel Index, Instrumental Activities of Daily Living, Neuropsychiatric Inventory Questionnaire, QoL, and caregiver burden using EuroQol-five dimension questionnaire and Zarit Burden Interview (ZBI. Differences in median scores postintervention were obtained. Further analysis of caregiver burden was undertaken utilizing the multidimensional classification of burden on the ZBI.Results: Thirty-four (61.8% patients were assessed to have met their goals (GAS score ≥50. Mean (standard deviation GAS score was 48.6 (6.5. Cognition goals were set in only 20.6%, followed by goals to improve engagement and socialization; reduce caregiver stress; and improve physical function, behavior, and mood. Median scores in the cognitive, functional, and QoL measures did not differ significantly pre- and postintervention. The intervention had a positive impact on role strain, a unique dimension of caregiver burden.Conclusion: This study provides evidence that a multimodal approach combining physical exercise and cognitive rehabilitation improves goal attainment and caregiver burden in individuals and caregivers of persons with mild dementia. Keywords: dementia, rehabilitation, goal attainment scaling

    Leung, Grace Suk Man; Leung, Timothy Yuk Ki; Ng, Monica Lai Tuen

    2013-01-01

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

  6. Market oriented approach by public utilities

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

    1989-08-01

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

  7. Safety objective oriented approach for RWE NPPs

    Even with respect to the management of beyond design incidents the safety objective oriented approach for the management of accidents is more universal than the event oriented approach. The potential propagation of an accident can be avoided or the effects of an accident can be limited through the application of the two elements of the safety objective concept. Regardless of the triggering event, the recurrent monitoring of safety objectives by means of safety variables allows the detection of whether the condition of the plant is still safely in the permissible range or whether there is a risk of a critical condition in safety engineering terms. With the measures compiled in the emergency manual the safety reserves can be fully utilized in actual practice using all the available plant technology. As a result, the residual risk still currently featured in the safety studies is further reduced. In order to contribute additional expert knowledge in the event of the hypothetical accidents examined in the paper, the shift personnel will be supported by the management for non-anticipated event sequences. The safety objective concept described has so far been only partly put into practice in the individual RWE (Rheinisch-Westfaelisches Elektrizitaetswerk AG) nuclear power stations. The full implementation of the concept is currently under way. The required documents are currently being drawn up and are being simulator tested to the extent possible. (author). 2 figs

    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.

    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.

  14. 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

    Blevins, Claire E; Banes, Kelsey E; Walker, Denise D; Stephens, Robert S; Roffman, Roger A

    2016-02-01

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

  6. A Data-Oriented Approach to Semantic Interpretation

    Bod, R; Scha, R; Bod, Rens; Bonnema, Remko; Scha, Remko

    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.

    2013-06-01

    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.

    Yannis Dimitriadis

    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.

  16. 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.

    I analyze observed choice between lotteries from an outcome-oriented point of view in the framework of choice between random variables. I characterize a choice maker, who faces a choice situation between lotteries, by (1) a surmising process that associates, with a pair of lotteries, a set of well-defined choice situations between random variables, and (2) a choice set that is a collection of well-defined choice situations. I give a partial axiomatic foundation of the theory. The theory is ap...

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

    Humphrey, Parris Taylor

    2014-01-01

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

  20. Game Portability Using a Service-Oriented Approach

    Steve Maddock

    2008-04-01

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

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

    Isak Taksa

    2008-01-01

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

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

  6. A service oriented approach for guidelines-based clinical decision support using BPMN.

    Rodriguez-Loya, Salvador; Aziz, Ayesha; Chatwin, Chris

    2014-01-01

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

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

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

    Seyyed Ayatollah Razmjoo

    2015-06-01

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

  13. Employee customer orientation in context: how the environment moderates the influence of customer orientation on performance outcomes.

    Grizzle, Jerry W; Zablah, Alex R; Brown, Tom J; Mowen, John C; Lee, James M

    2009-09-01

    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.

The experimental results show that our methods are effective and efficient.

  15. Recent advances in the compound-oriented and pattern-oriented approaches to the quality control of herbal medicines

    Wei Shuiyin

    2008-08-01

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

  19. Making The Most of Medical orientation; A New Approach.

    Dr Jonathan Taitz

    2004-02-01

    Full Text Available Orientating new junior medical staff can be a complex and time consuming task. Traditional models have typically involved a day or longer of lectures. This involves a large number of senior staff being available on the first day of term. It also means that junior staff not present on the first day had any access to an orientation program at all. Evaluation of our program confirmed the belief that the day was dull and that there was simply too much information for new staff to absorb. As a result of this feedback we extensively updated our orientation program. Pre-reading of the junior staff manual became compulsory. We departed from the traditional lecture style program and devised a new ten- station scenario based interactive program. The stations were designed to cover aspects of the hospital’s mandatory education and key educational requirements in order to function effectively on our campus. Station leaders were selected and trained in the goals of the new process. Several of our secondment sites were engaged in the development of the project topics. We hoped that our secondment sites would be relieved of some orientation responsibility if core material was delivered centrally. The strength of the new orientation is that it is portable, reproducible and uniform. It is also available via video conferencing. A single person can educate new staff in three hours if the need arises. Most importantly all new staff will have access to the program within a week of starting a term at our hospital.

  20. A new approach to the orientation of random hypergraphs

    Lelarge, Marc

    2012-01-01

    A h-uniform hypergraph H=(V,E) is called (l,k)-orientable if there exists an assignment of each hyperedge e to exactly l of its vertices such that no vertex is assigned more than k hyperedges. Let H_{n,m,h} be a hypergraph, drawn uniformly at random from the set of all h-uniform hypergraphs with n vertices and m edges. In this paper, we determine the threshold of the existence of a (l,k)-orientation of H_{n,m,h} for k>=1 and h>l>=1, extending recent results motivated by applications such as cuckoo hashing or load balancing with guaranteed maximum load. Our proof combines the local weak convergence of sparse graphs and a careful analysis of a Gibbs measure on spanning subgraphs with degree constraints. It allows us to deal with a much broader class than the uniform hypergraphs.

  14. How the behavioral approach system predicts everyday life outcomes.

    Izadikhah, Zahra; Jackson, Chris J

    2010-01-01

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

  15. A Framework for Assessing the Software Reusability using Fuzzy Logic Approach for Aspect Oriented Software

    Pradeep Kumar Singh

    2015-01-01

    Full Text Available Software reusability is very important and crucial attribute to evaluate the system software. Due to incremental growth of software development, the software reusability comes under attention of many researcher and practitioner. It is pretty easier to reuse the software than developing the new software. Software reusability reduces the development time, cost and effort of software product. Software reusability define the depth to which a module can be reused again with very little or no modification. However the prediction of this quality attribute is cumbersome process. Aspect oriented software development is new approach that introduce the concerns to overcome the issues with modular programming and object oriented programming. However many researcher worked on accessing the software reusability on object oriented system but the software reusability of aspect oriented system is not completely explored. This paper explores the various metric that affects the reusability of aspect oriented software and estimate it using fuzzy logic approach.

  16. Small Firm Internet Adoption: a market oriented approach

    Colin Jones

    2002-11-01

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

  17. VLTI auxiliary telescopes: a full object-oriented approach

    Chiozzi, Gianluca; Duhoux, Philippe; Karban, Robert

    2000-06-01

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

  18. VIMOS Instrument Control Software Design: an Object Oriented Approach

    Brau-Nogu, Sylvie; Lucuix, Christian

    2002-12-01

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

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

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

  20. Client Oriented Approach for Assisting Business Improvement Decision Making

    Diana Pitic

    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.

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

    Marinkovic, Stevan; Popovici, Emanuel

    2012-01-01

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

    Full Text Available In recent years there is growing pressure on the medical sector to reduce costs while maintaining or even improving the quality of care. A potential solution to this problem is real time and/or remote patient monitoring by using mobile devices.

  4. Typing linear algebra: A biproduct-oriented approach

    Macedo, Hugo,; Oliveira, José

    2013-01-01

    Interested in formalizing the generation of fast running code for linear algebra applications, the authors show how an index-free, calculational approach to matrix algebra can be developed by regarding matrices as morphisms of a category with biproducts. This shifts the traditional view of matrices as indexed structures to a type-level perspective analogous to that of the pointfree algebra of programming. The derivation of fusion, cancellation and abide laws from the biproduct equations makes...

  5. Multiple Triangulation Analysis: another approach to determine the orientation of magnetic flux ropes

    X.-Z. Zhou

    2006-07-01

    Full Text Available Another approach (Multiple Triangulation Analysis, MTA is presented to determine the orientation of magnetic flux rope, based on 4-point measurements. A 2-D flux rope model is used to examine the accuracy of the MTA technique in a theoretical way. It is found that the precision of the estimated orientation is dependent on both the spacecraft separation and the constellation path relative to the flux rope structure. However, the MTA error range can be shown to be smaller than that of the traditional MVA technique. As an application to real Cluster data, several flux rope events on 26January 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.

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

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

  8. THE ADOPTION OF MARKET ORIENTATION IN HIGHER EDUCATION INSTITUTIONS: APPROACHES, ANTECEDENTS AND CONSEQUENCES

    Amalia DUTU

    2014-06-01

    Full Text Available During the last few years, the entire business environment has changed, being characterized by volatility and discontinuities. Change has become so intense that companies have lost, on a large extent, their visibility and the strategic planning capacity. In order to operate in such a dynamic environment, companies should be flexible in the strategical, organizational and operational points of view. The higher education institutions are not an exception. Universities have to cope with this change. In this context, the adoption of market orientation approach and principles, which is a business’s concept and practice, may lead to a sustainable development and a higher adaptation capacity to change. Thus, the purpose of this study is to emphasise the approach of market orientation concept in the particular context of higher education institutions and to display some general factors that can intensify or inhibit the market orientation adoption, labelled as antecedents, but also the consequences of market orientation implementation.

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

    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

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

    Jonathan P. San Diego

    2008-12-01

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

Structural issues about basis are discussed first, then the Object Oriented Programming (OOP is aplied to modeling the main elements in this context. The model implementation is then discussed using C++ as programing language. To validate the proposed model, we apply on some feature basis from the University of Carolina, Irvine Machine Learning Database.

  14. A Main Object-oriented Projective Invariant Image Watermarking Approach

    Malik F. Alamaireh

    2007-01-01

    Full Text Available Digital Watermarking is a technology that enables to protect distributed digital content from unauthorized reuse. 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.

  15. PROPOSED MODEL FOR RESOURCE MANAGEMENT USING AUCTION ORIENTED APPROACH

    2012-09-01

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

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

    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.

Student groups are developing their projects in an interactive and collaborative manner.

  18. Evaluating nursing outcomes: a mixed-methods approach.

    Lane-Tillerson, Crystal; Davis, Bertha L; Killion, Cheryl M; Baker, Spencer

    2005-12-01

    Being overweight is regarded as the most common nutritional disorder of children and adolescents in the United States. The escalating problem of being overweight or being obese in our society indicates the need for treatment strategies that encompass an all-inclusive approach. Moreover, these strategies need to be comprehensively evaluated for their effectiveness. Nurses are in an excellent position to ensure that this occurs. The purpose of this study was to determine whether using a mixed-methods approach was an efficacious way to provide a comprehensive evaluation of the behavior modification benefits of a weight loss/weight management nursing intervention in African-American adolescent girls (13-17 years of age). The overall effectiveness of the intervention was evaluated by analyzing pre- and post-program measures of weight, body mass index, cholesterol, blood pressure, self-esteem, depression, and body image (quantitative data); conducting focus groups with mothers of the participants; and administering open-ended, written questionnaires to the participants (qualitative data). Findings from the quantitative data indicated favorable outcomes in weight, blood pressure, cholesterol, body mass index, self-esteem, and body image, indicating that progress had been made over the course of the program. Furthermore, qualitative data indicated that mothers of the participants observed positive behavioral changes related to eating and exercise patterns and participants demonstrated perception of these changes as well.

  19. A Workflow-Oriented Approach To Propagation Models In Heliophysics

    Gabriele Pierantoni

    2014-01-01

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

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

    Mechala Scott

    1992-03-01

    Full Text Available Within the classroom context, albeit school or university, intrinsic motivation can effectively be described and changed if a process-oriented approach is employed. The question is posed whether a process-oriented approach to motivation is acceptable to Christian education. To answer this question, intrinsic motivation and the process-oriented approach to motivation are described. A Christian view of self-knowledge and control, which are the main components of a process-oricnted approach to motivation, is subsequently given and the process-oriented approach to motivation is subjected to a Christian evaluation. The conclusions are drawn that this approach can fruitfully be used in Christian education, given that self-knowledge and control arc interpreted within the context of the concept of the student as Gods 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.

    Feature-centric comprehension of software is a prerequisite to incorporating modifications requested by users during software evolution and maintenance. However, feature-centric understanding of large object-oriented programs is difficult to achieve due to size, complexity and implicit cha......-racter of mappings between features and source code. In this paper, we address these issues through our unified approach to feature-centric analysis of object-oriented software. Our approach supports discovery of feature-code traceability links and their analysis from three perspectives and at three levels...

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

    Björn Frostell

    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.

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

    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.

  7. Compilation and synthesis for embedded reconfigurable systems an aspect-oriented approach

    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-...

  15. Socioeconomic status, parenting, and externalizing problems in African American single-mother homes: A person-oriented approach.

    Anton, Margaret T; Jones, Deborah J; Youngstrom, Eric A

    2015-06-01

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

  17. Research on the Rapid and Accurate Positioning and Orientation Approach for Land Missile-Launching Vehicle

    Kui Li

    2015-10-01

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

  18. A Systematic Knowledge Management Approach Using Object-Oriented Theory in Customer Complaint Management

    Wusheng Zhang

    2010-12-01

    Full Text Available Research into the effectiveness of customer complaint management has attracted researchers, yet there has been little discussion on customer complaint management in the context of systematic knowledge management approach particularly in the domain of hotel industry. This paper aims to address such gap through the application of object-oriented theory for which the notation of unified modelling language has been adopted for the representation of the concepts, objects, relationships and vocabularies in the domain. The paper used data from forty seven hotel management staff and academics in hospitalitymanagement to investigate lessons learned and best practices in customer complaint management and knowledge management. By providing insights into the potential of a knowledge management approach using object oriented theory, this study advances our understanding on how a knowledge management approach can systematically support the management of hotel customer complaints.

    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. A dynamic object-oriented architecture approach to ecosystem modeling and simulation.

    Dolph, J. E.; Majerus, K. A.; Sydelko, P. J.; Taxon, T. N.

    1999-04-09

    Modeling and simulation in support of adaptive ecosystem management can be better accomplished through a dynamic, integrated, and flexible approach that incorporates scientific and technological components into a comprehensive ecosystem-modeling framework. The Integrated Dynamic Landscape Analysis and Modeling System (IDLAMS) integrates ecological models and decision support techniques, through a geographic information system (GIS)-based framework. The Strategic Environmental Research and Development Program (SERDP) sponsored the development of IDLAMS. Initially built upon a GIS framework, IDLAMS is migrating to an object-oriented (OO) architectural framework. An object-oriented architecture is more flexible and modular. It allows disparate applications and dynamic models to be integrated in a manner that minimizes (or eliminates) the need to rework or recreate the system as new models are added to the suite. In addition, an object-oriented design makes it easier to provide run-time feedback among models, thereby making it a more dynamic tool for exploring and providing insight into the interactions among ecosystem processes. Finally, an object-oriented design encourages the reuse of existing technology because OO-IDLAMS is able to integrate disparate models, databases, or applications executed in their native languages. Reuse is also accomplished through a structured approach to building a consistent and reusable object library. This reusability can substantially reduce the time and effort needed to develop future integrated ecosystem simulations.

  1. Urban ninth-grade girls interactions with and outcomes from a design-oriented physics project

    Higginbotham, Thomas Eric Miksad

    Past literature has documented a shrinking but persistent gap in physics and engineering for females, both in school and in the workforce. A commonly recommended strategy to invite girls into science at the school level is to have students work on design-projects in groups, which has been shown to increase all students' learning outcomes and attitudes towards science. Students (n=28) in a ninth-grade inner-city physics class participated in such a project, in which they built remotely operated underwater vehicles (ROV's) over the course of one month. Students (n=23) in a comparison classroom learned the same content using the Active Physics curriculum during the same time frame. Mixed methods were used to study the ROV classroom. Students in both classes were given pre- and post-physics content tests. Qualitative data collected during the project included field notes, video, and teacher interviews. Macro-level data analysis was done, which informed further micro-analysis. Macro-analysis revealed significantly higher learning outcomes for the ROV class than for the non-ROV class. Within the ROV class, girls, and in particular, girls in female-majority groups had increased learning outcomes and high levels of interest and engagement with the project, while girls in mixed-sex and male-majority groups did not. Qualitative macro-analysis revealed that in all of the female-majority groups, females took leadership roles within the groups, while in all of the non female-majority groups, males took leadership roles. The only groups in which girls completely disengaged from the project were mixed-sex or male majority groups. Case studies and cross case analysis suggested that girls foregrounded group process over product, and used the level of group unity as a metric of the groups' success. Groups led by girls were more cooperative and exhibited distributed leadership and participation. These findings were interpreted through lenses of expectation states theory and social interdependence theory. This study suggests that the commonly recommended non-sexist strategy of using hands-on group work can be positive, but should be undertaken with conscious attention to group dynamics.

  2. A Pattern-Oriented Approach to a Methodical Evaluation of Modeling Methods

    Michael Amberg

    1996-11-01

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

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

    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

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

    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

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

    Kleanthis C. THRAMBOULIDIS

    2003-04-01

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

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

    Ramnarain, Umesh; Schuster, David

    2014-08-01

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

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

    2000-01-01

    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.

  6. Reliability Analysis of Electric Power Systems Using an Object-oriented Hybrid Modeling Approach

    Schläpfer, Markus; Kröger, Wolfgang

    2012-01-01

    The ongoing evolution of the electric power systems brings about the need to cope with increasingly complex interactions of technical components and relevant actors. In order to integrate a more comprehensive spectrum of different aspects into a probabilistic reliability assessment and to include time-dependent effects, this paper proposes an object-oriented hybrid approach combining agent-based modeling techniques with classical methods such as Monte Carlo simulation. Objects represent both technical components such as generators and transmission lines and non-technical components such as grid operators. The approach allows the calculation of conventional reliability indices and the estimation of blackout frequencies. Furthermore, the influence of the time needed to remove line overloads on the overall system reliability can be assessed. The applicability of the approach is demonstrated by performing simulations on the IEEE Reliability Test System 1996 and on a model of the Swiss high-voltage grid.

  7. A Knowledge-Based System Approach for Extracting Abstractions from Service Oriented Architecture Artifacts

    George Goehring

    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.

    2014-02-01

    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.

    Ehrich, Hans-Dieter

    1994-12-01

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

    1985-01-01

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

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

    Xie, Ning; Hachiya, Hirotaka; Sugiyama, Masashi

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

    2012-07-01

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

    2002-01-01

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

  1. An object-oriented approach for agrivultural land classification using rapideye imagery

    Sang, H.; Zhai, L.; Zhang, J.; An, F.

    2015-06-01

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

  2. A class hierarchical, object-oriented approach to virtual memory management in multiprocessor operating systems

    Campbell, R.; Russo, V.; Johnston, G. (Illinois Univ., Urbana, IL (USA). Dept. of Computer Science)

    1988-01-01

    The Choices family of operating systems exploits class hierarchies and object-oriented programming to facilitate the construction of customized operating systems for shared memory and networked multiprocessors. The software is being used in the Tapestry laboratory of interconnected multimaxes and hypercubes to study the performance of algorithms, mechanisms, and policies for parallel systems. This paper describes the architectural design and class hierarchy of the Choices virtual memory management system. The software and hardware mechanisms and policies of a virtual memory system implement a memory hierarchy that exploits the trade-off between response times and storage capacities. In Choices, the notion of a memory hierarchy is captured by abstract classes. Concrete subclasses of those abstractions implement a virtual address space, segmentation, paging, physical memory management, secondary storage, and remote (that is, networked) storage. Captured in the notion of a memory hierarchy are classes that represent memory objects. These classes provide a storage mechanism that contains encapsulated data and have methods to read or write the memory object. Each of these classes provide specializations to represent the memory hierarchy. They may be cached in physical memory. This paper describes the motivation for an object-oriented, class-hierarchical approach to virtual memory system design, and describes the overall architecture of such an approach, as it has been applied to Choices.

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

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

    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.

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

    Vandana Gupta

    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.

  10. An equation oriented approach to steady state flowsheeting of methanol synthesis loop

    An equation-oriented approach was developed for steady state flowsheeting of a commercial methanol plant. The loop consists of fixed bed reactor, flash separator, preheater, coolers, and compressor. For steady sate flowsheeting of the plant mathematical model of reactor and other units are needed. Reactor used in loop is a Lurgi type and its configuration is rather complex. Previously reactor and flash separator are modeled as two important units of plant. The model is based on mass and energy balances in each equipment and utilizing some auxiliary equations such as rate of reaction and thermodynamics model for activity coefficients of liquid. In order to validate the mathematical model for the synthesis loop, some simulation data were performed using operating conditions and characteristics of the commercial plant. The good agreement between the steady state simulation results and the plant data shows the validity of the model

  13. Assessing ecosystem services for informing land-use decisions: a problem-oriented approach

    Johannes Förster

    2015-09-01

    Full Text Available Assessments of ecosystem services (ES, that aim at informing decisions on land management, are increasing in number around the globe. Despite selected success stories, evidence for ES information being used in decision making is weak, partly because ES assessments are found to fall short in targeting information needs by decision makers. To improve their applicability in practice, we compared existing concepts of ES assessments with focus on informing land use decisions and identified opportunities for enhancing the relevance of ES assessments for decision making. In a process of codesign, building on experience of four projects in Brazil, China, Madagascar, and Vietnam, we developed a step-wise approach for better targeting ES assessments toward information needs in land use decisions. Our problem-oriented approach aims at (1 structuring ES information according to land use problems identified by stakeholders, (2 targeting context-specific ES information needs by decision makers, and (3 assessing relevant management options. We demonstrate how our approach contributes to making ES assessments more policy relevant and enhances the application of ES assessments as a tool for decision support.

  14. a New Approach to LAGEOS Spin Orientation and its Role in General Relativity Measurements

    Currie, Douglas; Dell'Agnello, Simone; Monache, Giovanni Dell; Tauraso, Roberto

    2008-06-01

    The two LAGEOS Satellites have addressed a variety of issues in Geophysics (GP) and General Relativity (GR). The extreme accuracy of laser ranging (currently approaching millimeter accuracy) now means that very small error sources act upon LAGEOS and have become important, affecting the study of GP (e.g., the tides) and GR (e.g., Lenses-Thirring Effect). Initial measurements and analysis of the spin orientation were first performed at the in the early 1990s at the University of Maryland. However, the spin rate of LAGEOS has slowed to the point that this method is no longer effective. A new observing approach (the "Pocket Modulation Effect") to determine the spin axis has been proposed by the first author. Data that addresses this method has been collected at various sites and is being analyzed at LNF/INFI. We will report on the physics involved in the PME and describe the laboratory data and simulations performed to validate the proposed approach, the LAGEOS data obtained at sites, the new analysis procedures and then address the impact of this new information.

  15. An applications-oriented approach to the development of virtual environments

    Crowe, Michael X.

    1994-01-01

    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.

  20. Object-oriented programming approach to CCD data acquisition and image processing

    Naidu, B. Nagaraja; Srinivasan, R.; Shankar, S. Murali

    1997-10-01

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

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

    Roman, Carolina

    2010-05-01

    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.

  3. The feasibility of an outcome approach to quality assurance--a report from one HMO.

    Schroeder, S A; Donaldson, M S

    1976-01-01

    Recent federal legislation has contained the stipulation that participating health maintenance organizations (HMOs) include a quality assurance program which stresses health outcomes. This provision was ostensibly directed at correcting alleged abuses in HMOs serving the urban poor. One version of the outcome method was employed for an 18-month period at an urban HMO caring for 2,000 Medicaid subscribers. The program involved comparing diagnostic accuracy and therapeutic outcomes for clinical conditions relevant to the study population with ideal standards established by the HMO. Three conditions were selected: contraception, depression, and hypertension. The results revealed widespread underdiagnosis (44-74%) in each condition and unacceptable therapeutic outcomes in two. Data collection was hampered by shifts in geography and financial eligibility among the denominator population and low response rates (38-63%) to telephone and mail surveys. Applying the general project guidelines to specific conditions proved considerably more difficult than anticipated. Further refinement of this approach to quality assessment must occur before its widespread use is feasible. Its effectiveness in improving quality remains to be seen. This experience raises doubts regarding the wisdom of legislating a specific outcome approach to quality assessment before feasibility and effectiveness have been demonstrated in organized health settings.

  7. A Multiple Model Approach to Track Head Orientation With Delta Quaternions.

    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. PMID:22692926

  8. The Adolescent Mentalization-based Integrative Treatment (AMBIT) approach to outcome evaluation and manualization: adopting a learning organization approach.

    Fuggle, Peter; Bevington, Dickon; Cracknell, Liz; Hanley, James; Hare, Suzanne; Lincoln, John; Richardson, Garry; Stevens, Nina; Tovey, Heather; Zlotowitz, Sally

    2015-07-01

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

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.

    2012-06-01

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

  11. System Level Power Management for Embedded Rtos: An Object Oriented Approach

    Ankur Agarwal

    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 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.

  14. Recovering Use Case Diagrams from Object Oriented Code: an MDA-based Approach

    Claudia T. Pereira

    2012-07-01

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

    2014-01-01

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

    2011-07-01

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

    Background Robotic surgery has been recently used as a novel tool for remote access thyroid surgery. We performed a meta-analysis of the current literature to examine the safety and oncological efficacy of robotic surgery compared to endoscopic and conventional approaches for different thyroid procedures. Methods A systematic search of the online data bases was done using the following (MeSH) terms "robotic surgery," "robotic thyroidectomy," "robot-assisted thyroidectomy," and "robot-assisted thyroid surgery." Outcomes measured included total operative time, length of hospital stay, postoperative thyroglobulin levels, and postoperative complications. Statistical differences were analyzed between groups through the standard means and/or relative risk by using STATA analytical software. Results In this study, 144 articles were identified; of which 18 of them met our inclusion criteria, totaling 4878 patients. Robotic approach was associated with longer total operative time (mean difference of 43.5 minutes) when compared to the conventional cervical approach (95% CI = 20.9-66.2; P Robotic approach was also found to have a similar risk of total postoperative complications when compared to the conventional and endoscopic approaches. Conclusion Robotic thyroid surgery is as safe, feasible and provides similar periperative complications and oncological outcomes when compared to both, conventional cervical and endoscopic approaches. However, robotic thyroid surgery is associated with longer operative time when compared to the conventional open approach. PMID:26525401

    2010-02-01

    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%.

  4. Gray matter alterations in chronic pain: A network-oriented meta-analytic approach

    Franco Cauda

    2014-01-01

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

  5. Changes in need satisfaction and motivation orientation as predictors of psychological and behavioural outcomes in exercise referral.

    Rahman, Rachel Jane; Thogersen-Ntoumani, Cecilie; Thatcher, Joanne; Doust, Jonathan

    2011-11-01

    Employing Self-Determination Theory (Deci & Ryan, 1985) as a theoretical framework, this study examined psychological need satisfaction and motivational regulations as predictors of psychological and behavioural outcomes in exercise referral (ER). ER patients (N = 293; mean age 54.49) completed the measures of motivational regulations, psychological need satisfaction, health-related quality of life, life satisfaction, anxiety, depression and physical activity at entry, exit and 6 months following the end of a supervised exercise programme. Change in (Δ) intrinsic motivation during the scheme significantly predicted adherence and Δ habitual physical activity. Δ psychological need satisfaction from entry to exit significantly predicted Δ habitual physical activity from exit to 6-month follow-up. Δ psychological need satisfaction significantly predicted Δ motivational regulation and Δ psychological outcomes. Contrary to expectations, Δ self-determined regulation did not significantly predict Δ psychological outcomes during the structured part of the scheme, however, it did significantly predict Δ in psychological outcomes from exit to 6-month follow-up. These findings expand on cross-sectional research to demonstrate that psychological need satisfaction during supervised ER longitudinally predicts motivational regulation and psychological outcomes up to 6 months after a structured programme.

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

    Kuo-Hsiung Chen

    2011-01-01

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

  13. Estimating fracture orientation from elastic-wave propagation: An ultrasonic experimental approach

    de Figueiredo, J. J. S.; Schleicher, J.; Stewart, R. R.; Dyaur, N.

    2012-08-01

    Elastic-wave propagation in fractured and cracked media depends on the dominant spatial orientation of the discontinuities. Consequently, compressional and shear-wave velocities can give valuable information about the orientation of the cracks. The main goal of this work is to estimate the preferential fracture orientation based on an analysis of cross-correlated S-wave seismograms and Thomsen parameters. For this purpose, we analyzed ultrasonic measurements of elastic (P and S) waves in a physical-modeling experiment with an artificially anisotropic cracked model. The solid matrix of the model consisted of epoxy-resin; small rubber strips simulate cracks with a compliant fill. The anisotropic cracked model consists of three regions, each with a different fracture orientation. We used the rotation of the S-wave polarizations for a cross-correlation analysis of the orientations, and P- and S-wave measurements to evaluate the weak anisotropic parameters γ and ɛ. The shear and compressional wave sources had dominant frequencies of 90 kHz and 120 kHz. These frequencies correspond to long wavelengths compared to the spacing between layers, indicating a nearly effective-media behavior. Integrating the results from cross-correlation with anisotropic parameter analysis, we were able to estimate the fracture orientation in our anisotropic cracked physical model. The γ parameter showed good agreement with the cross-correlation analysis and, beyond that, provided additional information about the crack orientation that cross-correlation alone did not fully resolve. Moreover, our results show that the shear waves are much more strongly influenced by, and can thus contain more information about, crack orientation than compressional waves.

    With object-oriented programming, classes and inheritance have sometimes been considered as a definitive answer to the need for modularity and reusability in programming languages. However, this view of object-oriented languages is often considered as too limited and many authors have claimed that classes do not make appropriate modules. On the one hand, separate concerns are generally distributed on a set of closely related classes, while on the other, a class implements several unrelated co...

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

    Gollmann Günter

    2011-03-01

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

  17. FAO/IAEA consultants' meeting on integrated approach for improving small scale market oriented dairy systems. Report

    A Consultants' Meeting was held at IAEA, Vienna from 21-24 August 2000 to discuss the need for, and to develop an FAO/IAEA Co-ordinated Research Project (CRP) to demonstrate increases in the productivity of small scale market oriented dairy systems using an integrated approach to improving nutrition, reproductive management and disease control. The meeting was attended by five consultants with expertise in specific aspects of research and development in dairy production, three external resource persons who were funded from their own institutes, a staff member of FAO's Animal Production Service, a representative of the IAEA's Department of Technical Co-operation and staff members of the Joint FAO/IAEA Division's Subprogramme on Animal Production and Health. The list of participants is given. The specific objectives of the meeting were to: Review the current research thrusts that are relevant to the objectives of the project, recommend areas that should be included and determine the most appropriate modalities for supporting these activities; Define the scientific scope of the project and recommend appropriate technologies and methods that should be applied in field and laboratory studies for obtaining the necessary information; Review the background document which has been prepared and make appropriate improvements and modifications; and Develop work plans, time scales, schedule of Research Co-ordination Meetings (RCMs) and the project framework matrix. The meeting was formally opened by Dr Martyn Jeggo, Head of the Animal Production and Health Section, who outlined the Sub-programme's mandate, medium-term strategy and how the planned CRP fits into this strategy. Dr Oswin Perera, the Scientific Secretary of the meeting, outlined the previous activities of the Sub-programme in animal nutrition and reproduction, discussed the background to the proposed project, and presented the objectives and expected outcomes of the meeting. The consultants and resource persons presented reviews on aspects of relevance to the proposed CRP. Subsequently, discussions were held in plenary sessions and in small groups to develop, modify and/or improve specific aspects of the draft project document. Finally, conclusions and recommendations were drafted, discussed and adopted

  18. Solving public passenger transportation problems: a need for policy reorientation. [Brokerage or consumer-oriented approach needed

    Davis, F.W. Jr.; Oen, K.

    1977-01-01

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

  19. Can kinematic approaches be used to predict shear fracture orientations for use in discrete fracture network models?

    Imber, Jonathan; Jones, Richard; Perry, Tom; Wightman, Ruth

    2013-04-01

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

  20. The effects of temperature on service employees' customer orientation: an experimental approach.

    Kolb, Peter; Gockel, Christine; Werth, Lioba

    2012-01-01

    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

  1. A DIALOGIC ENLIGHTENMENT PERSPECTIVE; APPROACH TO THE OTTOMAN AND EUROPEAN RELATIONS IN PSEUDO-ORIENTAL LETTERS

    Dr. Hasan BAKTIR

    2008-09-01

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

    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.

    Miao, Yongwu; Hermans, Henry

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

  5. Promulgate: an approach to Optimize the data transfer in Service Oriented Architecture

    B. Chandra Mouli , Prof. C. Rajendra

    2012-06-01

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

    2015-01-01

    Full Text Available Introduction. Risk stratification is nowadays crucial when estimating the patients 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.

  9. An Aspect-Oriented Programming-based approach to software development for fault detection in measurement systems

    Arpaia, P; Inglese, Vitaliano; Bernardi, Mario Luca; Di Lucca, Giuseppe; Spiezia, Giovanni

    2010-01-01

    An Aspect-Oriented Programming-based approach to the development of software components for fault detection in automatic measurement systems is proposed. Faults are handled by means of specific software units, the ``aspects{''}, in order to better modularize issues transversal to several components. As a case study, this approach was applied to the design of the fault detection software inside a flexible framework for magnetic measurements, developed at the European Organization for Nuclear Research (CERN). Experimental results of software modularity and performance measurements for comparing aspect- and objectoriented solutions in rotating coils tests on superconducting magnets are reported.

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

  13. Designing Logical Topology for Wireless Sensor Networks: A Multi-Chain Oriented Approach

    Quazi Mamun

    2013-02-01

    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.

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

    Alfred R. Brunsdon

    2009-09-01

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

    Buendia, M A; Santana, O; Conde, C A; Pineda, A M; Zamora, C; Lamas, G A; Sivina, M

    2013-10-01

    Aim: A retroperitoneal approach for abdominal aortic aneurysm repair has demonstrated similar short-term postoperative outcomes compared with the transperitoneal approach. However, there is no long-term survival data utilizing exclusively open repair via retroperitoneal approach. Methods: We have conducted a retrospective analysis to evaluate the long-term survival of 142 patients with infrarenal aortic aneurysm undergoing elective open surgical repair via a retroperitoneal approach. Results: Our cohort of patients consisted of 82% males, 59% whites, and a mean age of 72.67.7 years. The 30-day mortality rate was 3.5% for open repair via retroperitoneal approach. Post-operative complications were low, with renal failure (9.9%), pulmonary complication (9.9%), and limb ischemia (6.3%) being the most prevalent. Five years after surgery, the cumulative survival rate was 70.1%. Conclusion: The elective management of infrarenal aortic aneurysms with open repair via a retroperitoneal approach offers a good prognosis demonstrated with up to 5 year follow up. PMID:24104586

  1. A contour distance-based approach for multi-oriented and multi-sized character recognition

    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.

  2. Maintainability Prediction of Object Oriented Software System by Using Artificial Neural Network Approach

    Yajnaseni Dash

    2012-05-01

    Full Text Available Maintainability is an imperative attribute of software quality. However the prediction of this attribute is a cumbersome process. Therefore various methodologies are proposed so far to estimate the maintainability of software. Among them Artificial Neural Network is one of the sophisticated techniques which have immense prediction capability and this paper explores its application to evaluate maintainability of the object-oriented software. In this study maintenance effort was chosen as the dependent variable and principal components of object-oriented metrics as the independent variables. Prediction of maintainability is performed by Multi Layer Perceptron (MLP neural network model. The results obtained from the current study are also compared with other models and it is revealed that the presented model is more useful than the previous one.

  3. Identifying the Quality of Object Oriented Software System using Modularization Approach

    Ms. Pragati D. Chowhan, Prof. S. S. Dhande

    2013-02-01

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

  4. Nondestructive testing based on scanning-from-heating approach: application to nonthrough defect detection and fiber orientation assessment

    Belkacemi, Mohamed; Stolz, Christophe; Mathieu, Alexandre; Lemaitre, Guillaume; Massich, Joan; Aubreton, Olivier

    2015-11-01

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

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

    2009-01-01

    Full Text Available In today's rapidly changing environment the industries areinterested in executing business functions that has scope inmultiple applications. 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.

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

    Sens, Brigitte

    2010-01-01

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

  20. Computational protein design approaches with significant biological outcomes: progress and challenges

    Xiaoman Li

    2012-09-01

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

    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.

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

    Latimer, Eric A; Bond, Gary R; Drake, Robert E

    2011-09-01

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

    2012-09-01

    Full Text Available The authors discuss the experience of treating eating disorders at a psychoanalytically oriented therapeutic community in Italy. Teamwork and group activities are the bases of the treatment, at least to the point that the experience of the collectivity does not hinder the individual subjective expression of each patient. The treatment includes several different steps in the process of the admittance and release of patients and the subjectivation involved in the process is considered very important. A clinical vignette is presented at the end of the article.

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

    Sandra Klute

    2011-10-01

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

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

    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.

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

    Sanjay Misra; Ibrahim Akman; Murat Koyuncu

    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.

  12. The axis of orientation of the synlophe in the Heligmosomoidea (Nematoda, Trichostrongylina: a new approach

    Durette-Desset M.C.

    2005-09-01

    Full Text Available The definition of the axis of orientation of the synlophe is modified for the Heligmosomoidea so that one or two axes may be recognized. When two axes are present, their inclinations to the sagittal axis are different on the right and left sides, and we propose to name them right axis and left axis, respectively. During the course of evolution, starting from a single oblique axis (plesiomorphic state, an independent rotation of this axis on the right and left sides may bring about a double-axis state with a different inclination on both sides (derived state. When the rotation reaches 90° for both sides, the axis becomes simple once again and is superimposed to the frontal axis (most derived state.

    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.

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

    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.

  16. The Object Oriented Approach to Machine Physics Calculations with Java Technology

    Kadunc, M; Plesko, M; Tkacik, G

    2001-01-01

    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...

    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. .

    Carter, Thomas P; Spitalny, Kenneth C; Marsh, Naomi R; Eaton, Newell; Herrick, Sally A; H Riser, Marta

    2006-11-01

    Best practice research indicates a need for a policy shift toward positive youth development (YD) principles and strategies. The New York State Youth Development Team (YDT) is a public-private partnership of leading agencies whose holistic vision, "families, schools and communities partner to support the development of healthy, capable and caring youth," requires key stakeholders at all levels to address adverse youth health outcomes through effective partnerships. To transform the YDT vision into statewide practice requires committed actions (policy, funding, and training) at the state and community levels. Key lessons learned and experience-based recommendations that guide YD efforts in New York State can help state and local agencies move more to a positive YD approach that helps young people become healthy, caring, competent, and contributing adults, fully prepared to be parents, workers, leaders, entrepreneurs, and citizens of the future.

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

    Chambers, Timothy

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

    Web designers usually ignore how to model real user expectations and goals, mainly due to the large and heterogeneous audience of the Web. This fact leads to websites which are difficult to comprehend by visitors and complex to maintain by designers. In order to ameliorate this scenario, an approach for using the i* modeling framework in Web engineering has been developed in this paper. Furthermore, due to the fact that most of the existing Web engineering approaches do not consider how to de...

  3. Reliability-oriented multi-objective optimal decision-making approach for uncertainty-based watershed load reduction

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

  5. Design of the DISCovery project: tailored work-oriented interventions to improve employee health, well-being, and performance-related outcomes in hospital care

    Niks Irene MW

    2013-02-01

    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.

  9. A Contingency-Oriented Approach to Understanding Borderline Personality Disorder: Situational Triggers and Symptoms

    Miskewicz, Kelly; Fleeson, William; Arnold, Elizabeth Mayfield; Law, Mary Kate; Mneimne, Malek; Furr, R. Michael

    2015-01-01

    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

  10. Restructuring of burnup sensitivity analysis code system by using an object-oriented design approach

    A new burnup sensitivity analysis code system was developed with help from the object-oriented technique and written in Python language. It was confirmed that they are powerful to support complex numerical calculation procedure such as reactor burnup sensitivity analysis. The new burnup sensitivity analysis code system PSAGEP was restructured from a complicated old code system and reborn as a user-friendly code system which can calculate the sensitivity coefficients of the nuclear characteristics considering multicycle burnup effect based on the generalized perturbation theory (GPT). A new encapsulation framework for conventional codes written in Fortran was developed. This framework supported to restructure the software architecture of the old code system by hiding implementation details and allowed users of the new code system to easily calculate the burnup sensitivity coefficients. The framework can be applied to the other development projects since it is carefully designed to be independent from PSAGEP. Numerical results of the burnup sensitivity coefficient of a typical fast breeder reactor were given with components based on GPT and the multicycle burnup effects on the sensitivity coefficient were discussed.

  11. A class Hierarchical, object-oriented approach to virtual memory management

    Russo, Vincent F.; Campbell, Roy H.; Johnston, Gary M.

    1989-01-01

    The Choices family of operating systems exploits class hierarchies and object-oriented programming to facilitate the construction of customized operating systems for shared memory and networked multiprocessors. The software is being used in the Tapestry laboratory to study the performance of algorithms, mechanisms, and policies for parallel systems. Described here are the architectural design and class hierarchy of the Choices virtual memory management system. The software and hardware mechanisms and policies of a virtual memory system implement a memory hierarchy that exploits the trade-off between response times and storage capacities. In Choices, the notion of a memory hierarchy is captured by abstract classes. Concrete subclasses of those abstractions implement a virtual address space, segmentation, paging, physical memory management, secondary storage, and remote (that is, networked) storage. Captured in the notion of a memory hierarchy are classes that represent memory objects. These classes provide a storage mechanism that contains encapsulated data and have methods to read or write the memory object. Each of these classes provides specializations to represent the memory hierarchy.

  17. SELECTING LEXICAL MATERIAL WHILE TEACHING A FOREIGH LANGUAGE TO ADULTS – STUDENT-ORIENTED APPROACH

    Lyudmila Alexandrovna Kozubovskaya

    2015-08-01

    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.

  20. Effect of four approaches to oral feeding progression on clinical outcomes in preterm infants.

    Pickler, Rita H; Reyna, Barbara A; Wetzel, Paul A; Lewis, Mary

    2015-01-01

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

  1. Automatic Case-Based Reasoning Approach for Landslide Detection: Integration of Object-Oriented Image Analysis and a Genetic Algorithm

    Jie Dou

    2015-04-01

    Full Text Available This paper proposes an automatic method for detecting landslides by using an integrated approach comprising object-oriented image analysis (OOIA, a genetic algorithm (GA, and a case-based reasoning (CBR technique. It consists of three main phases: (1 image processing and multi-image segmentation; (2 feature optimization; and (3 detecting landslides. The proposed approach was employed in a fast-growing urban region, the Pearl River Delta in South China. The results of detection were validated with the help of field surveys. The experimental results indicated that the proposed OOIA-GA-CBR (0.87 demonstrates higher classification performance than the stand-alone OOIA (0.75 method for detecting landslides. The area under curve (AUC value was also higher than that of the simple OOIA, indicating the high efficiency of the proposed landslide detection approach. The case library created using the integrated model can be reused for time-independent analysis, thus rendering our approach superior in comparison to other traditional methods, such as the maximum likelihood classifier. The results of this study thus facilitate fast generation of accurate landslide inventory maps, which will eventually extend our understanding of the evolution of landscapes shaped by landslide processes.

    2004-01-01

    CERN's (European Organization for Nuclear Research) WISDOM project uses XML for the replication of data between different data repositories in a heterogeneous operating system environment. For exchanging data from Web-resident databases, the data needs to be transformed into XML and back to the database format. Many different approaches are employed to do this transformation. This paper addresses issues that make this job more efficient and robust than existing approaches. It incorporates the World Wide Web Consortium (W3C) XML Schema specification in the database-XML relationship. Incorporation of the XML Schema exhibits significant improvements in XML content usage and reduces the limitations of DTD-based database XML services. Secondly the paper explores the possibility of database independent transformation of data between XML and different databases. It proposes a standard XML format that every serialized object should follow. This makes it possible to use objects of heterogeneous database seamlessly usi...

  3. Long-term vestibulocochlear functional outcome following retro-sigmoid approach to resection of vestibular schwannoma.

    Abboud, Tammam; Regelsberger, Jan; Matschke, Jakob; Jowett, Nathan; Westphal, Manfred; Dalchow, Carsten

    2016-03-01

    The objective of this study was to evaluate long-term vestibulocochlear functional outcomes of patients operated for unilateral vestibular schwannoma via the retro-sigmoid approach. Patients who underwent vestibular schwannoma resection via retro-sigmoid approach between 2004 and 2008 at our institution, without prior surgical or radio-surgical therapy were considered to be eligible for this study. Preoperative auditory and vestibular symptoms were assessed retrospectively. Postoperative symptoms were prospectively assessed using a standardised questionnaire, pure tone audiometry, video-oculography, and rotary chair testing. Out of a total of 203 patients, 120 were eligible for this study, of whom 64 responded to follow-up requests and could be enrolled. Serviceable hearing was reported in 42 patients (66 %) preoperatively and was maintained in 18 (43 %) postoperatively. While no significant change in rate of tinnitus and balance impairment between pre- and postoperative periods was detected, vertigo decreased significantly (40 to 28 %, p < 0.001). Postoperative video-oculography demonstrated vestibular paresis in 80 %. Rotary chair testing demonstrated normal or central compensation in 84 %. Absence of central compensation was associated with postoperative balance disturbance (p = 0.035). Increasing tumour size and patient age, also decreasing quality of preoperative hearing were independent factors predictive of a postoperative non-serviceable hearing (p = 0.020, p = 0.039 and p = 0.002, respectively). Resection of vestibular schwannoma via the retro-sigmoid approach is associated with improvement in postoperative vertiginous symptoms. Absence of central compensation leads to increased postoperative balance disturbances. Preservation of serviceable postoperative hearing is associated with good preoperative hearing status, younger age, and smaller tumours. PMID:25700833

  7. Outcome assessment of the VADO approach in psychiatric rehabilitation: a partially randomised multicentric trial

    Mirabella Fiorino

    2006-04-01

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

  8. Favorable survival and metabolic outcome for children with diencephalic syndrome using a radiation-sparing approach.

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

Direct medical cost estimates were determined by the price of drugs in 2008 and the hospital costs. Pain was evaluated using the Numerical Rating Scale (NRS and number of pain crises; the Hospital Anxiety and Depression Scale, Sickness Impact Profile, and satisfaction with treatment and hospital team were evaluated. Assessments were performed at day 0 and 6 months after the beginning of treatment. All protocols showed a clinical improvement of pain control at month 6. The GBP+ROP protocol was the least expensive treatment, whereas surgery was the most expensive. With time, however, GBP+ROP tended to be the most and MVD the least expensive. No sequelae resulted in any patient after drug therapies, while after MDV surgery several patients showed important side effects. Data reinforce that, (1 TN patients should be carefully evaluated before choosing therapy for pain control, (2 different pharmacological approaches are available to initiate pain control at low costs, and (3 criteria for surgical interventions should be clearly defined due to important side effects, with the initial higher costs being strongly reduced with time.Keywords: trigeminal neuralgia, carbamazepine, gabapentin associated with ropivacaine, microvascular decompression, clinical outcomes, direct costs 

  10. A Decision-Oriented Approach for Detecting and Modeling Non-Stationary Flood Frequency

    Hecht, J. S.; Vogel, R. M.

    2014-12-01

    Changes in the frequency of extreme floods have been observed and anticipated in many hydrologic settings in response to numerous drivers of environmental change, including climate, land cover, and infrastructure. To help decision-makers design flood control infrastructure in settings with non-stationary hydrologic regimes, a parsimonious approach for detecting and modeling trends in extreme floods is needed. An approach using ordinary least squares (OLS) regression can accommodate nonstationarity in both the mean and variance of flood series while simultaneously offering a means of (i) analytically evaluating type I and type II trend detection errors, (ii) analytically generating expressions of uncertainty, such as confidence and prediction intervals, (iii) providing updated estimates of the frequency of floods exceeding the flood of record, (iv) accommodating a wide range of non-linear functions through ladder of powers transformations, and (v) communicating hydrologic changes in a single graphical image. Previous research has shown that the two-parameter lognormal distribution can adequately model the annual maximum flood distribution of both stationary and non-stationary hydrologic regimes in many regions of the United States. A simple logarithmic transformation of annual maximum flood series makes an OLS regression modeling approach especially suitable for creating a non-stationary flood frequency distribution with parameters that are conditional upon time or a physically meaningful covariate. While the heteroscedasticity of some OLS models may be viewed as an impediment, it also presents an opportunity for characterizing both the conditional mean and variance of annual maximum floods. Through a case study of an urbanizing watershed, we demonstrate that accounting for trends in both the mean and variance can yield substantially different estimates of time-dependent extreme flood quantiles than only considering trends in the mean. When applied to risk-based optimization, including trends in the variance strongly influences the flood magnitude for which flood control infrastructure should be designed over a given planning horizon. This approach can easily be extended to multivariate regression equations that take physically meaningful covariates into account.

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

    Barraclough, S

    1999-04-01

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

    2001-12-01

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

  16. Examination of the role of magnetic resonance imaging in multiple sclerosis: A problem-orientated approach

    McFarland Henry

    2009-01-01

    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.

  17. A mechanism-oriented approach to psychopathology: The role of Pavlovian conditioning.

    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.

  19. Reliability-oriented multi-objective optimal decision-making approach for uncertainty-based watershed load reduction.

    Dong, Feifei; Liu, Yong; Su, Han; Zou, Rui; Guo, Huaicheng

    2015-05-15

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

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

    Fuller, Richard L; Goldfield, Norbert

    2016-01-01

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

  3. A theory of change for positive developmental approaches to improving outcomes among emerging adults with serious mental health conditions.

    Walker, Janet S

    2015-04-01

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

  4. Pharmacokinetically guided dose adjustment of 5-fluorouracil: a rational approach to improving therapeutic outcomes.

    Saif, M Wasif; Choma, Adrienne; Salamone, Salvatore J; Chu, Edward

    2009-11-18

    Chemotherapy dosing of the fluoropyrimidine 5-fluorouracil (5-FU) is currently based on body surface area. However, body surface area-based dosing has been associated with clinically significant pharmacokinetic variability, and as such, dosing based on body surface area may be of limited use. The clinical activity of 5-FU is modest at standard doses, and in general, dosing is limited by the safety profile, with myelosuppression and gastrointestinal toxicity being the most commonly observed side effects. Various strategies have been developed to enhance the clinical activity of 5-FU, such as biochemical modulation, alterations in scheduling of administration, and the use of oral chemotherapy. Studies that have shown an association between plasma concentration with toxicity and clinical efficacy have shown that pharmacokinetically guided dose adjustments can substantially improve the therapeutic index of 5-FU treatment. These studies have shown that only 20%-30% of patients treated with a 5-FU-based regimen have 5-FU levels that are in the appropriate therapeutic range--approximately 40%-60% of patients are underdosed and 10%-20% of patients are overdosed. To date, 5-FU drug testing has not been widely used because of the lack of a simple, fast, and inexpensive method. Recent advances in testing based on liquid chromatography-mass spectroscopy and a nanoparticle antibody-based immunoassay for 5-FU may now allow for routine monitoring of 5-FU in clinical practice. We review the data on pharmacokinetically guided dose adjustment of 5-FU and discuss the potential of this approach to advance therapeutic outcomes. PMID:19841331

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

    Johann Engelbrecht

    2009-09-01

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

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

    Alfred R. Brunsdon

    2015-02-01

    Full Text Available From a South African perspective, pastoral care is typically concerned with the solving orresolving of critical issues such as marital crises or depression. It represents an approach thatis based on a medical or disease model, addressing deficits rather than strengths in the livesof counselees. Therapeutic developments in the fields of the narrative approach and positivepsychology have shifted the attention to the therapeutic nurturing of liberating stories andthe strengthening of virtues. Thus, the quality of the human experience by capitalising onwhat is healthy and intact is enhanced. This article will explore the notion that the pastoralprocess should aim at understanding and nurturing emotional and spiritual strengths withwisdom as the outcome, rather than trying to unravel spiritual deficits as strategy for healing.Such a positive approach relies on wisdom as a foundational virtue. By cultivating wisdom,counselees become fit for a well-lived life. In light of this, the necessity for widening ourtraditional pastoral horizons is discussed. Scripture and positive psychology are consideredas sources to inform the pastoral process on wisdom and the narrative is discussed as a meansto uncover and cultivate wisdom in the lives of counselees. Markers for a positive pastoralnarrative approach, aimed at the cultivation of wisdom, are suggested. This article endeavoursto contribute to the enrichment of pastoral practitioners frame of reference by drawing onthe insights of neighbouring helping-disciplines, like the narrative and positive psychologyemployed within a practical theological paradigm, hence contributing to the ongoing call(semper reformanda to always renew our theological endeavours.Wysheid as uitkoms van die pastorale proses: Nadenke oor n positiewe pastoraal-narratiewe benadering.

    We examine the roles of the outcome and process dimensions of environmental performance in determining financial performance as measured by Tobin’s q. Outcomes refer to the impacts of the firm on the natural environment, while processes are the firm’s actions to reduce these outcomes. We focus on a specific outcome—carbon emissions—and suggest that it affects Tobin’s q non-linearly. We find that firms achieve the highest financial performance when their carbon performance is neither low nor h...

  11. Sexual Orientation, Human Rights, and Corporate Sponsorship of the Sochi Olympic Games: Rethinking the Voluntary Approach to Corporate Social Responsibility

    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.

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

    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.

Overview of Literature Tuberculous spondylodiscitis in the elderly is increasing due to longer survival rates. It presents with varied clinical manifestations needing surgical management. Management in tuberculous spondylodiscitis has been scarcely reported in the elderly, with a paucity of data on the choice of implants and approach. Methods Sixteen patients (five males, 11 females) older than 70-years-of-age culture and/or histopathology proven tuberculous spondylodiscitis were included in the study. All patients were operated using a single posterior approach. Pedicle screw with rods (PS/rods) or spinal loop with sublaminar wires (SL/SLW) were used for fixation. Clinical and surgical details were recorded. Sagittal correction achieved postoperatively and loss of correction at follow-up were noted. Results The mean age was 73.6 years (range, 70 to 80 years). The mean follow up was 44.5 months (range, 24 to 84 months). The mean immediate postoperative correction of sagittal deformity was 11.3 degrees; this correction was lost by a mean of 3.1 degrees at last follow-up. All 10 patients with deficit showed neurological recovery and all but one of the seven non-walkers were capable of independent ambulation at follow-up. Patients with SL/SLW and PS/rods had similar radiological outcome at final follow up. Conclusions Operative management gives satisfactory results in elderly patients with tuberculous spondylodiscitis. The posterior approach provides adequate exposure for decompression and rigid fixation, providing satisfactory clinical and radiological outcomes. SSL/SLW and pedicle screw rod construct both give similar radiological results if used appropriately in patients.

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

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

    Ghosh, Arpita

    2012-01-01

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

  1. [Concept extraction of graduate research by modified grounded theory approach and creating of rubric oriented to performance evaluation].

    2015-01-01

      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

  4. Breastfeeding and the child cognitive outcomes: a propensity score matching approach.

    Jiang, Miao; Foster, E Michael; Gibson-Davis, Christina M

    2011-11-01

    To estimate the effect of breastfeeding initiation and duration on child development outcomes. 3,271 children and their mothers participating in the Child Development Supplement of the Panel Study of Income Dynamics provide data for these analyses. Main outcomes include Woodcock Johnson Psycho-Educational Battery-Revised (WJ-R) test score (letter word, passage comprehension, applied problem, and broad reading), and Wechsler Intelligence Scale for Children-Revised (WISC-R) test score at the 2002 survey. Controlled variables include family, maternal, and child characteristics, many of which can be traced back to the year the child was born. The analytic technique is propensity score matching with multiple imputations. After using propensity scores to adjust for confounding factors, breastfeeding initiation showed statistically significant effects but the practical scale remains small. Breastfeeding duration showed a non-linear effect on those outcomes and most of the effects are not significant. The effects of breastfeeding on child's cognitive outcomes are modest in practical terms. The non-linear effects suggest that selection into breastfeeding may account for the increased score of children who are breastfed. PMID:20848171

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

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

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

    Ozlem Demirtas Bagdonas

    2016-02-01

    Full Text Available The recent changes in Turkey's Cyprus policy have spurred a new debate as to whether Turkey's foreign policy has been Europeanized, now that the previous sources of tension have seemingly been abated. Focusing on how this policy has been defined in the official discourse in relation to Turkey's European orientation, hence taking European orientation as a domestically constructed discourse, this study seeks to show that it would be problematic to view the government's tendency to refrain from framing the issue as a security issue as an intractable process of according with the EU's stance on the issue. By the same token, if 'Europeanness' is liberated from the preset values and situated in its domestic context, it would be equally misleading to interpret Turkey's security-centered approach to Cyprus as a non-European feature of Turkish foreign policy, and to view the recurrent Cyprus crises as a deviation from Turkey's European orientation.

  12. Human reliability assessment in surgery--a new approach for improving surgical performance and clinical outcome.

    Cuschieri, A.

    2000-01-01

    Surgical operative performance is currently assessed by audit of morbidity, mortality and, especially in patients with cancer, in terms of long-term outcome. Its chief merit is the identification of problems and sub-optimal results by individual surgeons/centres. There is one aspect of audit that constitutes its intrinsic weakness, the verdict on performance it gives is always retrospective--the problem is identified because of the bad results thrown up by analysis of the data. As a result, t...

    2016-01-01

    Background Blood pressure (BP) control may have different effects on cardiovascular (CV) and renal outcomes in diabetes. We examined the impact of systolic BP (SBP) on renal and CV outcomes in a post hoc analysis in the Olmesartan Reducing Incidence of Endstage Renal Disease in Diabetic Nephropathy Trial. Methods We stratified mean follow-up SBP into three categories (?130, 131140 and >140 mmHg) and used a Cox regression model to estimate the hazard ratio (HR, 95% confidence interval) for the outcomes. The composite renal outcome was doubling of serum creatinine, end-stage renal disease and all-cause death. The composite CV outcome included CV death, nonfatal stroke, nonfatal myocardial infarction, hospitalization for unstable angina or heart failure, revascularization and lower extremity amputation. We also compared the slope of estimated glomerular filtration rate (eGFR) in all three groups. Results After a mean follow-up period of 3.2 years, the follow-up SBP was linearly associated with risk of renal outcomes in all 566 patients. In patients with heavy proteinuria (?1 g/gCr), a follow-up SBP > 130 mmHg was associated with an HR of 2.33 (1.623.36) for renal outcomes with referent to SBP ? 130 mmHg. In patients without history of CV disease, a follow-up SBP > 140 mmHg was associated with an HR of 2.04 (1.233.40) for CV outcomes with referent to SBP 140 mmHg, respectively (P = 0.008 between ?130 and 131140, P 140 mmHg). Conclusion In Asian type 2 diabetic patients with chronic kidney disease and heavy proteinuria, reduction of SBP ? 130 mmHg was associated with greater renoprotection than cardioprotection. However, our results emphasize the need to individualize BP targets in type 2 diabetes. PMID:26152402

    2008-01-01

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

  17. A new modelling approach of a multizone building to assess the influence of building orientation in Saharan climate

    Hamdani Maamar

    2015-01-01

    Full Text Available Orientation of building is a very important factor which is directly connected to the standards of thermal comfort within building. It is guided by natural elements like sunlight and its intensity, direction of the wind, seasons of the year and temperature variations. The orientation effect of a non-air-conditioned building on its thermal performance has been analyzed in terms of direct solar gain and temperature index for hot-dry climates. This paper aims at introducing an improved methodology for the dynamic modeling of buildings by the thermal nodal method. The evaluation is derived from a series of computer simulations. As a result, the influence of orientation changing depends on the floors and exterior walls constructing materials, the insulation levels and application of the inseparable rules of the bioclimatic design.

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

  2. Rethinking The Role of Media in the Outcome of 21. Century Conflicts: A Media-Policy Interaction Approach

    Muhammed Kürşad Özekin

    2014-02-01

    Full Text Available The primary objective of this article is to explore the role of media in the outcome of 21st-century conflicts in the light of two cases: the War on Terror and the 2008-2009 Gaza War.  In line with this objective, this study first critically evaluates two main theoretical approaches to media-politics relations in international conflicts: CNN effect and Manufacturing Consent media theory. Then, it offers an insight into media-policy interaction model both as a solution to the theoretical deadlock between these theories and as a conceptual framework for understanding the role of media in determining the outcome of 21st-century conflicts. Lastly, the question of ‘To what extent do the media determine the outcome of 21st-century conflicts?’ is answered by analyzing media coverage of the War on Terror and the 2008-2009 Gaza War in the light of media-policy interaction model.

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

    BernhardHommel

    2012-10-01

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

  5. Perceived social isolation, evolutionary fitness and health outcomes: a lifespan approach.

    Hawkley, Louise C; Capitanio, John P

    2015-05-26

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

  6. An outcomes approach to stroke care: the importance of teamwork and evidence-based nursing care.

    Middleton, Sandy

    2012-04-01

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

  7. The Quadrella: A novel approach to analyzing optimal outcomes after permanent seed prostate brachytherapy

    Background and purpose: To study a four-point combined analysis (Quadrella) of optimal outcome among patients treated with exclusive permanent seed prostate brachytherapy (PB), as defined by the likelihood of achieving disease control and preserving normal urinary, gastro-intestinal (GI) and sexual function. Materials and methods: 384 patients with localized prostate cancer underwent PB at our institution with 125I at a dose level of 144 Gy. Subjects with erectile dysfunction who did not respond to medication were excluded. 281 patients with minimum 3-year follow-up were evaluated. Patients with concurrent biochemical progression-free survival (bPFS), absent urinary and GI toxicities (grade 0 toxicities according to CTCAE v 3.0) and preserved sexual potency (with our without medication) were classified as the Quadrella group. Results: Among the 281 patients analyzed, the Quadrella was achieved in 49.1%, 48.0%, 50.4%, 41.7% and 65.2% in years 3–7, respectively. bPFS rates were 82.6–96.1%, corresponding potency rates were 63.6–82.3%, and normal urinary and GI function rates were 64.8–82.6% and 95–100%, respectively. By multivariate analysis, significant predictors of Quadrella were age (p = 0.015), baseline IPSS (p = 0.03) and time since PB (p = 0.02). Conclusion: Urinary and sexual toxicity remained the most common reasons for excluding patients from a perfect outcome (Quadrella), defined by strict criteria. This analysis can be useful for subsequent comparison between treatment modalities

  8. Ideological Challenges to Changing Strategic Orientation in Commodity Agriculture

    2014-01-01

    Why do some firms not change their strategic orientation despite economic incentives to do so? Most current literature on changing strategic orientations focuses on an antecedents and outcomes approach to business orientations. Intimated, but rarely addressed is, first, the idea that strategic...... changes. In assessing the transition to organic production and marketing in a commodity agriculture context we find that contending ideologies restrict its adoption. In addition, we suggest that strategic orientations are not adopted or contested solely within firms but also among them. We find that...... ideological contestation among firms in this context takes the form of a marketplace drama between a chemical, productonist and an organic orientation in which several forms of legitimacy are mobilized by protagonists....

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...

  13. Supporting Enactment of Aspect Oriented Business Process Models : an approach to separate cross-cutting concerns in action

    Jalali, Amin

    2013-01-01

    Coping with complexity in Information Systems and Software Engineering is an important issue in both research and industry. One strategy to deal with this complexity is through a separation of concerns, which can result in reducing the complexity, improving the re-usability, and simplifying the evolution.Separation of concerns can be addressed through the Aspect Oriented paradigm. Although this paradigm has been well researched in the field of programming, it is still in a preliminary stage i...

  14. Facilitating innovation: an action-oriented approach and participatory methodology to improve innovative social practice in agriculture.

    Engel, P.G.H.

    1995-01-01

    This study focuses upon the social organization of innovation. It makes use of insights from knowledge and information systems research, development sociology, management science and applied philosophy and seeks answers to the following questions: What do social actors, individuals and/or organizations, actually do to innovate their practices? How do they organize themselves? Can this be managed or facilitated, and if so, how? The research is exploratory rather than conclusion-oriented and sy...

  15. Comparison of outcomes after extended thymectomy for myasthenia gravis: bilateral thoracoscopic approach versus sternotomy.

    Shiono, Hiroyuki; Kadota, Yoshihisa; Hayashi, Akio; Okumura, Meinoshin

    2009-12-01

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

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

    Debra Maria Jones

    2015-09-01

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

  18. Configurational explanation of marketing outcomes : a fuzzy-set qualitative comparative analysis approach

    Vassinen, Antti

    2012-01-01

    As marketing, as a function and a process, is required to explain itself with more transparency, new tools and comprehensive analysis processes must be created and adopted, so that marketing performance and its determinants can systematically be understood and developed. In this dissertation, I present fuzzy-set qualitative comparative analysis (‘FS/QCA’; Ragin, 2000; Fiss, 2008; Rihoux and Ragin, 2009; and others) as a novel approach to assessing marketing performance. My key argument i...

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

    Kang, John; Schwartz, Russell; Flickinger, John; Beriwal, Sushil

    2015-12-01

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

  2. An interdisciplinary, outcome-based approach to astmospheric CO2 mitigation with planted southern pine forests

    Martin, T.; Fox, T.; Peter, G.; Monroe, M.

    2012-12-01

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

  3. Using the health action process approach to predict and improve health outcomes in individuals with type 2 diabetes mellitus

    Full Text Available Mariana MacPhail,1 Barbara Mullan,2 Louise Sharpe,1 Carolyn MacCann,1 Jemma Todd1 1School of Psychology, University of Sydney, Sydney, NSW, Australia; 2School of Psychology and Speech Pathology, Curtin University, Bentley, WA, Australia Background: The purpose of this study was to explore the predictive utility of the Health Action Process Approach (HAPA and test a HAPA-based healthy eating intervention, in adults with type 2 diabetes mellitus. Materials and methods: The study employed a prospective, randomized, controlled trial design. The 4-month intervention consisted of self-guided HAPA-based workbooks in addition to two telephone calls to assist participants with the program implementation, and was compared to “treatment as usual”. Participants (n=87 completed health measures (diet, body mass index [BMI], waist circumference, blood pressure, blood glucose levels, lipid levels, and diabetes distress and HAPA measures prior to the intervention and again upon completion 4 months later. Results: The overall HAPA model predicted BMI, although only risk awareness and recovery self-efficacy were significant independent contributors. Risk awareness, intentions, and self-efficacy were also independent predictors of health outcomes; however, the HAPA did not predict healthy eating. No significant time × condition interaction effects were found for diet or any HAPA outcome measures. Conclusion: Despite the success of HAPA in predicting health outcomes for those with type 2 diabetes mellitus, the intervention was unsuccessful in changing healthy eating or any of the other measured variables, and alternative low-cost health interventions for those with type 2 diabetes mellitus should be explored. Keywords: intervention, healthy eating, theory, risk awareness, self-efficacy

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

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

  5. The laparoscopic transperitoneal approach for irreducible inguinal hernias: Perioperative outcome in four patients

    Jagad Rajan

    2009-01-01

    Full Text Available Background : Incarceration and strangulation are the most feared complications of inguinal hernia. Till date, incarcerated hernias have traditionally been treated by conventional open repair. Reports are now available for the feasibility of laparoscopic repair of incarcerated inguinal hernia. Here, we described our experience with the transperitoneal approach for incarcerated hernias. Materials and Methods : Between January 2008 and May 2008, four patients were presented with a history of irreducible hernia, abdominal distention and vomiting. All the patients had right-sided inguinal hernia. Reductions of the hernia contents were not possible in any patient. The patients were treated on emergency basis with laparoscopic transabdominal preperitoneal hernia repair. Retrospective analyses of all the patients were done. Results: Reduction of the bowel was achieved in all but one patient, who required the division of the internal ring on lateral side. Transperitoneal mesh repair was performed. No major complications were encountered. One patient developed seroma formation that was treated conservatively. Conclusion: Laparoscopic transperitoneal approach has the advantage of observation of the hernia content for a longer period of time. The division of the internal ring can be done under direct vision. Other intra-abdominal pathology and opposite side hernia can be diagnosed and treated at the same time.

  6. Six Month Outcomes of a Peer-Enhanced Community Reinforcement Approach for Emerging Adults with Substance Misuse: A Preliminary Study.

    Smith, Douglas C; Davis, Jordan P; Ureche, Daniel J; Dumas, Tara M

    2016-02-01

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

  7. Improving outcomes for youth with ADHD: a conceptual framework for combined neurocognitive and skill-based treatment approaches.

    Chacko, Anil; Kofler, Michael; Jarrett, Matthew

    2014-12-01

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

  8. Reducing volcanic risk on Fogo Volcano, Cape Verde, through a participatory approach: which outcome?

    Texier-Teixeira, P.; Chouraqui, F.; Perrillat-Collomb, A.; Lavigne, F.; Cadag, J. R.; Grancher, D.

    2014-09-01

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

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

    Amit Khatri

    2011-01-01

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

  10. 'Miracle baby': an outcome of multidisciplinary approach to neurotrauma in pregnancy.

    Neville, Grace

    2012-01-01

    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.

  11. System-oriented approach for the modeling and thermodynamic analysis of new energy concepts; Systemtechnische Vorgehensweise zur Modellierung und thermodynamischen Analyse neuer Energiekonzepte

    2008-07-01

    New energetic technologies are built up more and more frequently. Their internal structure can be compared with the internal structure of process engineering systems. In comparison to the infinitely large number of comparison processes (cycles) in chemical process engineering, the number of thermodynamic comparison processes is very limited. Under this aspect, the authors of the contribution under consideration report on a system-oriented approach for modelling and for the thermodynamic analysis of new energy concepts. The modelling of complicated energy concepts must consider thermodynamic aspects. Apparatus capacities have to be included.

  12. Reconsidering the Incompatibility Between European Orientation and Cyprus Policy: Westphalian and Post-Westphalian Approaches to Turkey’s Cyprus Policy and the EC/EU

    Özlem Demirtas Bagdonas

    2010-10-01

    Full Text Available The recent changes in Turkey’s Cyprus policy have spurred a new debate as to whether Turkey’s foreign policy has been Europeanized, now that the previous sources of tension have seemingly been abated. Focusing on how this policy has been defined in the official discourse in relation to Turkey’s European orientation, hence taking European orientation as a domestically constructed discourse, this study seeks to show that it would be problematic to view the government’s tendency to refrain from framing the issue as a security issue as an intractable process of according with the EU’s stance on the issue. By the same token, if 'Europeanness' is liberated from the preset values and situated in its domestic context, it would be equally misleading to interpret Turkey’s security-centered approach to Cyprus as a non-European feature of Turkish foreign policy, and to view the recurrent Cyprus crises as a deviation from Turkey's European orientation.

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

    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

  17. Determining the interviewer effect on CQ Index outcomes: a multilevel approach

    Winters Sjenny

    2010-08-01

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

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

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

  19. A multi-institutional approach to implement fruit fly low prevalence and free areas in Central America: Outcomes and constraints

    Full text: For the purpose of boosting the fruit and vegetable exports of the Central American countries through fruit fly suppression/eradication actions, new approaches are used: - A multilateral alliance instead of isolated efforts. Thus, four international organisations, two donors Government institutions and the region's seven countries joined their efforts, coordinated by the IAEA; - A strategy of incremental enlargement of isolated low prevalence or free areas, instead of the old approach of attempting to eradicate the pest from the entire region; and - The use of pilot experimental areas, on which all elements that play a key role in a pest-free production-exports system are applied, instead of focusing only on some technologies in the field. Outcomes include the implementation of medfly-free areas in Honduras, Nicaragua and Costa Rica, and Panama is also in the process of doing so. Guatemala is presently negotiating with the Mexican Government the export of peach from its fruit fly-free zone in the Department of Quetzaltenango. Major constraints encountered are: - Weak alliances among the international organisations, - Troublesome coordination between Governments and the producers-exporters, - Insufficient trained civil servants in the Government and, - Insufficient funding to transfer the actions to bigger areas.

    2012-04-01

    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.

  1. Mindfulness-Oriented Recovery Enhancement versus CBT for co-occurring substance dependence, traumatic stress, and psychiatric disorders: Proximal outcomes from a pragmatic randomized trial.

    2016-02-01

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

    Full Text Available El Oriente Medio ha sido siempre centro de atención debido a sus problemas e importancia económica para el mundo. Es además fuente de una considerable cantidad de petróleo y gas para el mundo, así como el lugar donde puede ser obtenido más barato. Este artículo asume un enfoque sistémico para entender el Oriente Medio y ubicarlo dentro de la política mundial. En el Oriente Medio hay varias instituciones que conectan la región al mundo y que, por tanto, tienen un cierto grado de influencia en la conformación de la política regional. Esta estructura institucional es importante en la localización del Oriente Medio en la política mundial, porque cada una de ellas tiene una agenda, una inclinación, y unas prioridades diferentes. Al entender la diversidad de las organizaciones regionales también se evidencia que el Oriente Medio no es una unidad, sino que tiene varios centros de poder.The Middle East has always been center of attention for its problems and economic importance to the world. The Middle East is the source of a considerable amount of the world’s oil and gas and is the place where it can be most cheaply obtained. This article takes a systemic approach to understand the Middle East and locate it within the global politics. In the Middle East there are various institutions that connect the region to the world. These institutions have a certain degree of influence in shaping regional politics. This institutional structure is important in locating the Middle East in global politics because each of them has different agenda, inclination and priories. Understanding the diversity of regional organizations will also show that the Middle East is not a single unity, rather it has various power centers.

  5. Reflecting resiliency: openness about sexual orientation and/or gender identity and its relationship to well-being and educational outcomes for LGBT students.

    Kosciw, Joseph G; Palmer, Neal A; Kull, Ryan M

    2015-03-01

    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

  6. Segmentation and Recognition of Handwritten Kannada Text Using Relevance Feedback and Histogram of Oriented Gradients – A Novel Approach

    2016-01-01

    Full Text Available India is a multilingual country with 22 official languages and more than 1600 languages in existence. Kannada is one of the official languages and widely used in the state of Karnataka whose population is over 65 million. Kannada is one of the south Indian languages and it stands in the 33rd position among the list of widely spoken languages across the world. However, the survey reveals that much more effort is required to develop a complete Optical Character Recognition (OCR system. In this direction the present research work throws light on the development of suitable methodology to achieve the goal of developing an OCR. It is noted that the overall accuracy of the OCR system largely depends on the accuracy of the segmentation phase. So it is desirable to have a robust and efficient segmentation method. In this paper, a method has been proposed for proper segmentation of the text to improve the performance of OCR at the later stages. In the proposed method, the segmentation has been done using horizontal projection profile and windowing. The result obtained is passed to the recognition module. The Histogram of Oriented Gradient (HoG is used for the recognition in combination with the support vector machine (SVM. The result is taken as the feedback and fed to the segmentation module to improve the accuracy. The experimentation is delivered promising results.

  7. A direct approach for instantaneous 3D density field reconstruction from background-oriented schlieren (BOS) measurements

    Nicolas, F.; Todoroff, V.; Plyer, A.; Le Besnerais, G.; Donjat, D.; Micheli, F.; Champagnat, F.; Cornic, P.; Le Sant, Y.

    2016-01-01

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

  8. Competitiveness through strategic orientation

    Diego Monferrer

    2012-12-01

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

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

    K M Sreejith; M Radhakrishna; K S Krishna; T J Majumdar

    2011-08-01

    The 85E Ridge extends from the Mahanadi Basin, off northeastern margin of India to the Afanasy Nikitin Seamount in the Central Indian Basin. The ridge is associated with two contrasting gravity anomalies: negative anomaly over the north part (up to 5N latitude), where the ridge structure is buried under thick Bengal Fan sediments and positive anomaly over the south part, where the structure is intermittently exposed above the seafloor. Ship-borne gravity and seismic reflection data are modelled using process oriented method and this suggest that the 85E Ridge was emplaced on approximately 1015 km thick elastic plate (Te) and in an off-ridge tectonic setting. We simulated gravity anomalies for different crust-sediment structural configurations of the ridge that were existing at three geological ages, such as Late Cretaceous, Early Miocene and Present. The study shows that the gravity anomaly of the ridge in the north has changed through time from its inception to present. During the Late Cretaceous the ridge was associated with a significant positive anomaly with a compensation generated by a broad flexure of the Moho boundary. By Early Miocene the ridge was approximately covered by the postcollision sediments and led to alteration of the initial gravity anomaly to a small positive anomaly. At present, the ridge is buried by approximately 3 km thick Bengal Fan sediments on its crestal region and about 8 km thick pre- and post-collision sediments on the flanks. This geological setting had changed physical properties of the sediments and led to alter the minor positive gravity anomaly of Early Miocene to the distinct negative gravity anomaly.

    2008-12-01

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

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

    Purpose: To evaluate whether a multimodal approach including craniospinal irradiation (CSI) improves treatment outcome in nongerminomatous germ cell tumor (NGGCT) patients. Methods and Materials: We reviewed the records of 32 patients with NGGCTs. Fourteen patients belonged to the intermediate prognosis group (immature teratoma, teratoma with malignant transformation, and mixed tumors mainly composed of germinoma or teratoma), and 18 patients belonged to the poor prognosis group (other highly malignant tumors). Patients with pure germinoma or mature teratoma were excluded from this study. Nineteen patients were treated with a combination of surgery, chemotherapy, and radiotherapy (RT); 9 patients received chemotherapy plus RT; 3 patients received surgery plus RT; and 1 patient received RT alone. Twenty-seven patients received CSI with a median of 36 Gy (range, 2041 Gy) plus focal boost of 1830.6 Gy, and 5 patients received whole-brain RT (WBRT) (2036 Gy) or focal RT (50.454 Gy). The rate of total and subtotal resection was 71.9%. The median follow-up for surviving patients was 121 months. Results: Treatment failed in 7 patients. Three of the 5 patients who received focal RT or WBRT had local failure. Four cerebrospinal fluid (CSF) failures occurred after CSI. No failure occurred in the intermediate prognosis group. Ten-year recurrence-free survival (RFS) and overall survival (OS) for all patients were 77.6% and 74.6%, respectively. Ten-year RFS for the intermediate and poor prognosis groups were 100% and 61.1%, respectively (p = 0.012). OS for the two groups were 85.1% and 66.7%, respectively (p = 0.215). Tumor histology and CSI were significant prognostic factors for RFS, and CSI was significantly associated with OS. Conclusions: A multimodal approach was effective for treating NGGCTs. CSI should be considered for patients with poor prognostic histology.

    Full Text Available 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.

  15. A hidden Markov model approach to analyze longitudinal ternary outcomes when some observed states are possibly misclassified.

    Benoit, Julia S; Chan, Wenyaw; Luo, Sheng; Yeh, Hung-Wen; Doody, Rachelle

    2016-04-30

    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.

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

    French Andrew S

    2012-12-01

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

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

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

    2016-01-01

    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.

  2. Diversity-oriented approaches to unusual ?-amino acids and peptides: step economy, atom economy, redox economy, and beyond.

    Kotha, Sambasivarao; Goyal, Deepti; Chavan, Arjun S

    2013-12-20

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

    A five-year Coordinated Research Project (CRP) entitled 'Integrated approach for improving small scale market oriented dairy systems' is currently being implemented by the Food and Agriculture Organization and the International Atomic Energy Agency, through their Joint Programme on 'Nuclear Techniques in Food and Agriculture'. The objectives are to (a) identify and prioritize the constraints and opportunities in the selected dairy farms; (b) determine the most important limiting factors; (c) develop intervention strategies; (c) assess the economic impact of the interventions; (d) develop methodologies for recording and demonstrating the economic impact; and (e) promote the adoption and dissemination of proven strategies and methodologies. Fifteen institutes in developing as well as developed countries are participating in the project, through ten research contracts (Bangladesh, Cameroon, Pakistan, Paraguay, Peru, South Africa, Sri Lanka, Tanzania, Tunisia and Venezuela), one technical contract (Peru) and four research agreements (Malaysia, U.K., U.S.A. and Uruguay). The initial phase of the project, which focused on the conduct of Participatory Rural Appraisals and Economic Opportunity Surveys in the countries of the research contract holders, has now been completed. This paper describes the background to the CRP approach and the procedures used for developing, initiating and implementing this project. PMID:18265863

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

    2014-01-01

    BACKGROUND: Total hip replacement provides pain relief and improves physical function and quality of life in patients with end-stage hip osteoarthritis. The incidence of hip replacement operations is expected to increase due to the growing elderly population. Overall, the posterior approach and...... lateral approach are the two most commonly used approaches for hip replacement operations. The posterior approach is associated with an increased risk of revision due to dislocations, and some studies have shown that the lateral approach is associated with reduced patient-reported outcomes, including...... a prospective, double blinded, parallel-group controlled trial with balanced randomisation [1: 1]. Patients with hip osteoarthritis scheduled for hip replacement surgery, aged 45-70 years, will be consecutively recruited and randomised into two groups.

  8. Orientations and Outcome of Interdisciplinary Research

    Valentin, Finn; Norn, Maria Theresa; Alkærsig, Lars

    2016-01-01

    The importance of interdisciplinary research in accelerating the progress and commercialization of science is widely recognized, yet little is known about how academic research self-organizes towards interdisciplinarity. In this paper, we therefore explore the micro-level behavior of researchers as...... they venture into a promising space for interdisciplinary research, namely translational research—a bridge between basic and applied biomedical research. More specifically, we ask (1) whether the researchers who choose to engage in translational research have a strong scientific record, (2) how...... highly cited research, while in others it is not, and look for explanations for this difference. Our results show that translational research draws higher citations when it involves university researchers from the most basic end of the disciplinary spectrum, and when its issues are directed at basic...

  9. An Approach to Acquiring, Normalizing, and Managing EHR Data From a Clinical Data Repository for Studying Pressure Ulcer Outcomes.

    Padula, William V; Blackshaw, Leon; Brindle, C Tod; Volchenboum, Samuel L

    2016-01-01

    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.

    Full Text Available According to recent analyses, many strategic projects are part of a “New Urban Policy” favouring private developments and enhancing gentrification and social exclusion. Alternative projects should be more transformative, integrated and emancipatory. In order to test these claims for the Flemish region, I use Moulaert and Nussbaumer’s model (2005a on the concept of social innovation to evaluate the socio-spatial innovation capacity of two Flemish strategic projects. The analysis suggests that social innovation is possible but that Flemish strategic projects are strongly affected by market, property and management oriented approaches.Volgens recente analyses zijn vele strategische projecten onderdeel van een “Nieuw Stedelijk Beleid”, dat private ontwikkeling, sociale verdringing en exclusie bevordert. Alternatieve projecten zouden meer transformatief, geïntegreerd en emancipatorisch (moeten zijn. Om deze uitspraken te testen voor de Vlaamse situatie, gebruikt dit artikel een model van Moulaert en Nussbaumer’s (2005a concept van sociale innovatie en evalueert daarmee de sociaal-ruimtelijke innovatiecapaciteit van twee Vlaamse strategische projecten. De analyse suggereert dat sociale innovatie mogelijk is, maar dat Vlaamse strategische projecten sterk beïnvloed worden door markt-, eigendoms- en managementgerichte benaderingen.

  13. The use of health-related quality of life (HRQOL in children and adolescents as an outcome criterion to evaluate family oriented support for young carers in Germany: an integrative review of the literature

    Schnepp Wilfried

    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 problems most accurate. Conclusion The KIDSCREEN questionnaires seems adequate to evaluate the intervention as their items cover young carer's needs and problems most accurate.

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

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

    2012-04-01

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

    2011-01-01

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

    2007-02-01

    A review of evidence on the benefits and challenges of student orientation is used in this article alongside experiences of orientation days on a children's ward to consider ways in which such programmes could be improved. Orientation to clinical placements can enhance learning by helping students to feel they fit in, reduce anxiety and increase motivation to learn through early identification of learning outcomes. However, there are challenges in the practical implementation of orientation including timing of students' starting dates, staff time, consistency and level of information and teaching. Increased involvement of individual mentors could improve orientation and optimise students' learning experiences. PMID:17326556

  3. Dynamic patient data bases: the foundation of an integrated approach to outcome measures for the healthcare professionals.

    Kwok, H K; Stevens, N

    1995-01-01

    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 answers to the 5 W's (who, what, where, when, and why) together with intervention and service result reports. A dynamic common patient database is the center of the system and is accessible to all with proper authorization. Common data elements are collected from routine work flow without extra data entry and this information is subsequently shared. Data collection is a continuous process. We believe that every process is the outcome of another sub-process or event. The design of the dynamic patient database incorporates patient-specific costing and outcome evaluation, user-defined flexible data entry forms, user-defined access control, outcome evaluation rules and information semantic rules. Such a patient database would provide the flexibility needed to accommodate diverse methodologies to evaluate outcomes whether it they be medical, cost, access and/or other combination of measures. The system was developed on a PC-based Network technology, using FOXPRO (XBase) as the database development tool incorporating advanced technology such as distributed processing and fault tolerant computing. We chose PC-based technology because it is economical, having relatively low maintenance costs and requires no major dependency on vendors. The developed system produces patient-specific reports with many dimensions. The reports are user-defined. The system reports general data, CMG, RGN, LOS, Expected LOS, and other user-defined demographic data. Resource utilization, financial costs, and result reportings are produced together with rule-based outcome assessments of any type of measures, including, but not limited to, pre-set functional/health goals, user satisfaction, clinicianUs text or codified comments etc. It provides the framework for continually capturing data at a practical, work-flow level. The incorporation of a dynamic patient database as the driving forece of an integrated, rule-based administration, financial and patient data system will provdie the tools for healthcar PMID:8591238

    In epidemiology, researchers try to answer questions about exposures and their effects (associations) on a variety of outcomes of interest. Most times, the collected data comes from observational studies, meaning that the researcher did not control the exposure to which each subject under study was exposed, like it is done in clinical trials. Additionally, researches collect information on other variables which could act as potential confounders of exposure. Estimation of adjusted association...

  8. A grading matrix assessment approach to align student performance to Threshold Learning Outcomes (TLOs in a large first year biology class

    Lesley Lluka

    2015-03-01

    Full Text Available In our large first year biology course, we aim to provide students with clear links between the course delivery framework and assessment. In the first semester of offering in 2008, we determined grades using the traditional weighted average of marks for the assessment tasks. However, of the 99% of students who passed with an aggregate of at least 50%, the lowest performing student obtained only 21% for the examination. Since Semester 2 2008, we have graded the course using a grading matrix approach with specified standards for all the individual assessment components. Analysis of results from this approach showed that 85-89% of students obtained a passing grade, for which a minimum score of 45% for the examination was required. The grading matrix approach provides a measure of each student’s higher order learning of concepts and skills that can be mapped to threshold learning outcomes for the students’ programs of study.

Main Outcomes Measured. The percentage of women achieving HbA1c values <5.8%, normal vaginal delivery and having a large for-gestational-age newborn were evaluated. Results. Despite a significant reduction in outpatient clinic visits in the experimental group, particularly in insulin-treated women (2.4 versus 4.6 hours per insulin-treated woman resp.; P<.001, no significant differences were found between the experimental and traditional groups regarding HbA1c levels (all women had HbA1c <5.8% during pregnancy, normal vaginal delivery (40.8% versus 54.2%, resp.; P>.05 and large-for-gestational-age newborns (6.1% versus 8.3%, resp.; P>.05. Conclusions. The system significantly reduces the need for outpatient clinic visits and achieves similar pregnancy, delivery, and newborn outcomes.

  11. A New Approach to Modeling Drop-Pair Collisions: Predicting the Outcome through a Fluidic-Mechanical System Analogy

    van Noordt, Paul; Hidrovo, Carlos

    2009-11-01

    The study of microfluidics has proven to be of great value in many engineering and scientific applications. Because of the small scales involved, microfluidics requires only small sample sizes, which can result in shorter reaction and analysis times, relatively cheap costs, and little waste. In this study, we investigate the process of two drops colliding head-on in order to gain a better understanding of the mechanisms that govern the outcome of the collision. The relationship between kinetic and surface energy of the colliding drops is considered, as is the viscosity of the intervening gaseous medium, as factors that govern the outcome. The collision process is modeled by a squeeze-flow problem involving both planar and non-planar geometry, with attention given to the deformation of the interacting surfaces. Based on the nature of the collision process, an analogy is made between the fluidic systems of colliding liquid bodies and a mechanical mass-spring-damper system. Examination of the analogous mechanical system yields the derivation of an effective damping ratio, ζ^*, which is used to predict the outcome of the drop-drop collision. Predictions made by utilizing the effective damping ratio are then compared to numerical results and experimental data found in the literature.

  13. Student performance and their perception of a patient-oriented problem-solving approach with audiovisual aids in teaching pathology: a comparison with traditional lectures

    Arjun Singh

    2010-12-01

    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

  18. Measuring and recording outcome.

    Murphy, P J

    2012-07-01

    Achieving good health outcomes for patients is the fundamental purpose of healthcare. What really matters to patients is the outcome of an intervention and the effect it will have on their wellbeing and life expectancy. After media coverage, and public enquiry into high mortality rates for paediatric cardiac surgery at the Bristol Royal Infirmary during the early 1990s, mortality rates for paediatric cardiac surgical procedures decreased dramatically both in Bristol and nationally. There can be little doubt that one of the prime 'drivers for change' was the placement of outcome data into the public domain. After events in Bristol, the Society for Cardiothoracic Surgery in Britain and Ireland (SCTS) has taken the lead in measuring and publishing clinical outcome data. It has also discussed how outcome data could be used to assess an individual's clinical performance and how, in the future, this might be linked to continuing professional development, appraisal, and revalidation. Measuring quality and outcome in healthcare is complex. Ideal outcome measures should be specific, sensitive, reliable, responsive, validated, timely, and easy to measure. Monitoring of outcomes can be 'process' orientated or 'clinically' orientated. The 2010 National Health Service (NHS) White Paper aimed for an NHS which 'moves away from centrally driven process targets and focuses on delivering outcomes which matter to people'. Measuring outcome in anaesthesia is problematic. There are issues around clinical coding, risk adjustment, the influence of clinical teamworking, and environmental factors. The National Institute of Academic Anaesthesia (NIAA) has identified that the description of clinical practice in anaesthesia and perioperative medicine is currently limited by a lack of valid, reliable quality measures. The NIAA suggests that there is a requirement for further research into identifying the anaesthetic outcome indicators which are most relevant to patients, and then benchmarking the performance of anaesthetic departments and anaesthetists.

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

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

  3. Oriental Africa

    Hester, du Plessis.

    2008-01-01

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

  12. Learning Outcomes in Two Different Teaching Approach in Nursing Education in Iran: E-Learning versus Lecture

    Neda Mehrdad

    2011-05-01

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

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

    Cassandra Kenning

    2014-08-01

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

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

    Emmett, B.; Anthony, S.; Chadwick, D.; Cross, P.; Swetnam, R.; Jackson, B. M.; Smart, S.; Skates, J.

    2014-12-01

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

    2013-04-01

    The food choices in childhood have high a probability of being carried through into their adulthood life, which then contributes to the risk of many non-communicable diseases. Therefore, there is a need to gather some information about children's views on foods which may influence their food choices for planning a related dietary intervention or programme. This paper aimed to explore the views of children on foods and the types of foods which are usually consumed by children under four food groups (snacks, fast foods, cereals and cereal products; and milk and dairy products) by using focus group discussions. A total of 33 school children aged 7-9 years old from Selangor and Kuala Lumpur participated in the focus groups. Focus groups were audio-taped, transcribed and analyzed according to the listed themes. The outcomes show that the children usually consumed snacks such as white bread with spread or as a sandwich, local cakes, fruits such as papaya, mango and watermelon, biscuits or cookies, tea, chocolate drink and instant noodles. Their choices of fast foods included pizza, burgers, French fries and fried chicken. For cereal products, they usually consumed rice, bread and ready-to-eat cereals. Finally, their choices of dairy products included milk, cheese and yogurt. The reasons for the food liking were taste, nutritional value and the characteristics of food. The outcome of this study may provide additional information on the food choices among Malaysian children, especially in urban areas with regard to the food groups which have shown to have a relationship with the risk of childhood obesity.

    To describe the details of the foraminoplastic superior vertebral notch approach (FSVNA) with reamers in percutaneous endoscopic lumbar discectomy (PELD) and to demonstrate the clinical outcomes in limited indications of PELD. Retrospective data were collected from 64 patients who underwent PELD with FSVNA from August 2012 to April 2014. Inclusion criteria were high grade migrated disc, high canal compromised disc, and disc protrusion combined with foraminal stenosis. The clinical outcomes were assessed using by the visual analogue scale (VAS), Oswestry Disability Index (ODI) and modified MacNab criteria. Complications related to the surgery were reviewed. The procedure used a unique approach, using the superior vertebral notch as the target and performing foraminoplasty with only reamers under C-arm control. The mean age of the 55 female and 32 male patients was 52.73 years. The mean F/U period was 12.24.2 months. Preoperative VAS (8.241.25) and ODI (67.815.4) score improved significantly at the last follow-up (VAS, 1.931.78; ODI, 17.1415.7). Based on the modified MacNab criteria, excellent or good results were obtained in 95.3% of the patients. Postoperative transient dysthesia (n=2) and reoperation (n=1) due to recurred disc were reported. PELD with FSVNA could be a good method for treating lumbar disc herniation. This procedure may offer safe and efficacious results, especially in the relatively limited indications for PELD.

    Introduction Transcatheter aortic valve replacement has been developed as an alternative option for surgical high-risk or inoperable patients with severe symptomatic aortic stenosis. Aim of the study Aim of the study was to evaluate the outcomes of patients undergoing transapical aortic valve replacement as a single-strategy option by a single-center multidisciplinary heart team. Material and methods Between June 2009 and December 2014, 41 patients underwent transapical transcatheter aortic valve implantation (TA-TAVI) at our institution. All patients received Edwards SAPIEN balloon expandable pericardial valves (Edwards Lifesciences, Irvine, CA, USA). Our center followed a “clear transapical strategy” for all patients. Results The mean age of the patients was 79.6 years, and the mean logistic EuroSCORE was 21.06 ± 12.82%. Fifteen patients (36.6%) underwent redo operations. Complications included stroke (n = 1), re-exploration for bleeding or cardiac tamponade (n = 4), renal failure requiring temporary hemodialysis (n = 4) and permanent pacemaker implantation (n = 3). There were no myocardial infarctions or coronary obstruction. The total 30-day mortality rate was 17.1% (7 patients). Postoperative intensive care unit stay was 4.6 ± 5.7 days, and mean hospitalization was 11.6 ± 7.2 days. Conclusions The TA-TAVI approach provides good results in terms of early and midterm outcomes. This approach is feasible and safe for patients who have high surgical risk. PMID:26336490

    Boris Petrovitch Zakharchenya (1928-2005) This issue is dedicated to the memory of Boris Petrovich Zakharchenya, who died at the age of 77 in April 2005. He was an eminent scientist and a remarkable man. After studying physics at Leningrad University he joined the Physico-Technical Institute (now the A F Ioffe Institute) in 1952 and became the co-worker of Evgeny Feodorovich Gross, shortly after the exciton was discovered in his laboratory. The experiments on cuprous oxide crystals in the visible spectral range showed a hydrogen-like spectrum, which was interpreted as excitonic absorption. The concept of the exciton had been conceived some years earlier by Jacov Frenkel at the Physico-Technical Institute. Immediately after joining Gross, Zakharchenya succeeded in producing spectra of unprecedented quality. Subsequently the heavy and the light hole series were found. Also, Landau splitting was discovered when a magnetic field was applied. The interpretation of the discovery was thrown into doubt by Russian colleagues and it took some time, before the correct interpretation prevailed. Shortly before his death, Boris wrote the history of the discovery of the exciton, which has recently been published in Russian in a book celebrating the 80th anniversary of his birth [1]. The book also contains essays by Boris on various themes, not only on physics, but also on literature. Boris was a man of unusually wide interests, he was not only fascinated by physics, but also loved literature, art and music. This can be seen in the first article of this issue The Play of Light in Crystals which is an abbreviated version of his more complete history of the discovery of the exciton. It also gives a good impression of the personality of Boris. One of us (GL) had the privilege to become closely acquainted with him, while he was a guest professor at the University of Würzburg. During that time we had many discussions, and I recall his continuing rage on the wrong attribution of the priority of the discovery in the literature, which was partly caused by the existence of the Iron Curtain. I had already enjoyed contact with Boris in the 1980s when the two volumes of Landau Level Spectroscopy were being prepared [2]. He was one of the pioneers of magneto-optics in semiconductors. In the 1950s the band structure of germanium and silicon was investigated by magneto-optical methods, mainly in the United States. No excitonic effects were observed and the band structure parameters were determined without taking account of excitons. However, working with cuprous oxide, which is a direct semiconductor with a relative large energy gap, Zakharchenya and his co-worker Seysan showed that in order to obtain correct band structure parameters, it is necessary to take excitons into account [3]. About 1970 Boris started work on optical orientation. Early work by Hanle in Germany in the 1920s on the depolarization of luminescence in mercury vapour by a transverse magnetic field was not appreciated for a long time. Only in the late 1940s did Kastler and co-workers in Paris begin a systematic study of optical pumping, which led to the award of a Nobel prize. The ideas of optical pumping were first applied by Georges Lampel to solid state physics in 1968. He demonstrated optical orientation of free carriers in silicon. The detection method was nuclear magnetic resonance; optically oriented free electrons dynamically polarized the 29Si nuclei of the host lattice. The first optical detection of spin orientation was demonstrated by with the III-V semiconductor GaSb by Parsons. Due to the various interaction mechanisms of spins with their environment, the effects occurring in semiconductors are naturally more complex than those in atoms. Optical detection is now the preferred method to detect spin alignment in semiconductors. The orientation of spins in crystals pumped with circularly polarized light is deduced from the degree of circular polarization of the recombination radiation. The major results of the systematic work on optical orientation, both experimental and theoretical, at the Ioffe Institute and the Ecole Normale Supérieure in Paris are documented in the book Optical Orientation, edited by F Meier and B P Zakharchenya in the series Modern Problems in Condensed Matter Sciences [4], in which the foundations of optical orientation are comprehensively presented by renowned authors. This book is still the unsurpassed standard work in the field. If one asks what has become new since that publication in 1984 it is obviously the arrival of low-dimensional structures, two-dimensional heterostructures and zero-dimensional quantum dots. It has turned out that the quantum confinement can significantly modify the spin lifetime and the spin relaxation. The experimental work on spin alignment was done by a relative small number of researchers. However, the situation has substantially changed during the last decade. Research on spin-related phenomena has become very popular and the word 'spintronics' was coined. Spin research is no longer considered to be somewhat esoteric, since the replacement of silicon microelectronics based on the electron charge by spin-based electronics is being discussed. Whether these proposals can be realized remains to be seen. But one consequence has been a worldwide increase of high level basic research in spin phenomena. Another line of current research which has contributed to the popularity of spin-related research is quantum computing, based on spin-qubits. To be useful, solid state systems require long spin relaxation times and weak interaction with the environment. This is indispensable for low error rates. The difficulties in achieving these goals have been extensively discussed in the literature. Nowadays, because of the volume and diversity of spin-related work worldwide, a book on optical orientation like that edited by Meyer and Zakharchenya does not seem possible, so in this special issue of Semiconductor Science and Technology we try, with examples, to give an impression of that current state of research. The articles will not be discussed individually but their titles reveal that most deal with low-dimensional systems. The study of spin relaxation plays a major role. Interface effects at the ferromagnet/semiconductor boundary are subtle and important for spin injection from a ferromagnet. Each of the contributions is a combination of review and recent results and stands by itself. The affiliations of the authors reveal that the majority come from St Petersburg, clearly indicating that the heritage of Boris Zakharchenya is alive and thriving. We would like to thank all authors for their cooperation, especially for delivering their manuscripts in a reasonable time. Claire Bedrock and Adam Day of the IOP Publishing deserve thanks for their support in the publication process. We are much indebted to Ruslana Zakharchenya for making the manuscript on the discovery of the exciton available and especially to Nina Nikolaevna Vasil'eva for her translation.

    Real estate marketing is still focused on McCarthy's 4-P or marketing-mix approach. In today's volatile markets the 4-P approach will no longer lead to satisfying results. It neglects an inherent strategic approach, lacks a process-oriented view and is rather focussed on the product than the customer and the customer's needs. Therefore, the author presents an integrative process oriented real estate marketing approach. Firstly, this approach is aligned with the property's position in its life...

    This paper discusses the results of a Small Business Innovation Research (SBIR) project. The initial application involved decomposition of a large database across multiple processors to improve the speed of processing compound queries. The commercial outcome was a tourist information system with a point-to-point driving direction program called MAPPER. A distributed, object-oriented approach was used for the general design, while a spatial decomposition was used to divide the database into computationally manageable pieces. The resulting system is highly flexible with respect to both modifications and reuse.

    Objectives. To assess the validity, reliability, and responsiveness to change of a patient self-reported questionnaire combining the Widespread Pain Index and the Symptom Severity Score as well as construct outcome measures and comorbidities assessment in fibromyalgia patients. Methods. The PROMs-FM was conceptualized based on frameworks used by the WHO Quality of Life tool and the PROMIS. Initially, cognitive interviews were conducted to identify item pool of questions. Item selection and reduction were achieved based on patients as well as an interdisciplinary group of specialists. Rasch and internal consistency reliability analyses were implemented. The questionnaire included the modified ACR criteria main items (Symptom Severity Score and Widespread Pain Index), in addition to assessment of functional disability, quality of life (QoL), review of the systems, and comorbidities. Every patient completed HAQ and EQ-5D questionnaires. Results. A total of 146 fibromyalgia patients completed the questionnaire. The PROMs-FM questionnaire was reliable as demonstrated by a high standardized alpha (0.886–0.982). Content construct assessment of the functional disability and QoL revealed significant correlation (p management.

  10. Percutaneous and minimally invasive approaches to mitral valve repair for severe mitral regurgitation-new devices and emerging outcomes.

    Shamoun, Fadi E; Craner, Ryan C; Seggern, Rita Von; Makar, Gerges; Ramakrishna, Harish

    2015-01-01

    Mitral valve disease is common in the United States and around the world, and if left untreated, increases cardiovascular morbidity and mortality. Mitral valve repair is technically more demanding than mitral valve replacement. Mitral valve repair should be considered the first line of treatment for mitral regurgitation in younger patients, mitral valve prolapse, annular dilatation, and with structural damage to the valve. Several minimally invasive percutaneous treatment options for mitral valve repair are available that are not restricted to conventional surgical approaches, and may be better received by patients. A useful classification system of these approaches proposed by Chiam and Ruiz is based on anatomic targets and device action upon the leaflets, annulus, chordae, and left ventricle. Future directions of minimally invasive techniques will include improving the safety profile through patient selection and risk stratification, improvement of current imaging and techniques, and multidisciplinary education.

  12. Analytical approaches to image orientation and stereo digitization applied in the Budnlab software. (Polish Title: Rozwiazania analityczne zwiazane z obsluga procesu orientacji zdjec oraz wykonywaniem opracowan wektorowych w programie Bundlab)

    Kolecki, J.

    2015-12-01

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

    Presented is a retrospective outcome study of a 15-year single institutional experience with a contemporary cohort of patients with hypoplastic left heart syndrome and complex that underwent a "Giessen Hybrid" stage I as initial palliation. Hybrid approach consisting of surgical bilateral pulmonary artery banding and percutaneous duct stenting with or without atrial septum manipulation was developed from a rescue approach to a first-line procedure. Comprehensive Aristotle score defined pre-operative condition. Fifteen-year follow-up mortality is reported as occurring within the staged univentricular palliation or before and after biventricular repair. Hybrid stage I was performed in 154 patients; 107 should be treated by single ventricle palliation, 33 by biventricular repair (BVR), 7 received heart transplantation, and 7 were treated by comfort care, respectively. Overall 34 children died. The Aristotle score (mean value 18.2 ± 3) classified for univentricular circulations in newborns did not have statistical impact on the outcome. Two patients died during stage I (1.2%), and the interstage I mortality was 6.7%, and stage II mortality 9%, respectively. Stage III was up to now performed in 57 patients without mortality. At 1 year, the overall unadjusted survival of HLHS and variants was 84% and following BVR 89%, respectively. The Fifteen-year survival rate for HLHS and variants was 77%, with no significant impact of birth weight of less than 2.5 kg. In conclusion, Hybrid stage I fulfilled the criteria of life-saving approach. In our institution, Hybrid procedure replaced Norwood-staged palliation with a considerable mid- and long-term survival rate. Considering interstage mortality close surveillance is mandatory.
