  5. Market oriented approach by public utilities

    Energy Technology Data Exchange (ETDEWEB)

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

    1989-08-01

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

    2003-01-01

    The healthcare environment has been impacted tremendously by higher patient acuity, cost-cutting measures, an increase in litigation, and increased expectations by an educated generation of healthcare consumers. This has led to the need to continually measure, assess, and improve quality. These activities must consider not only patient clinical outcomes, but also customer service ratings and financial outcomes. Quality improvement requires a collaborative approach to succeed, and the need to build a cohesive and effective multidisciplinary team is critical for positive outcomes. Strategies to build a culture of teamwork include incorporating total quality management principles into every level of the organization, seeking participation from every discipline and level of the organization, and recognizing employees for their efforts. Infusion nurses have an excellent opportunity to contribute their expertise to any multidisciplinary team that impacts the outcomes of infusion patients. In addition, team-building and quality improvement may prove to be excellent career moves for infusion nurses looking to further specialize their practice. PMID:12544365

  11. Leadership and management principles for outcomes-oriented organizations.

    Science.gov (United States)

    Goonan, Kathleen Jennison; Stoltz, Patricia K

    2004-04-01

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

    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.

    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.

  3. APPROACHES TO STUDY EDUCATIONAL AND OCCUPATIONAL TRAJECTORIES AND OUTCOMES

    Directory of Open Access Journals (Sweden)

    Tovar-García, Edgar Demetrio

    2012-04-01

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

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

    CERN Document Server

    Humphrey, Parris Taylor

    2014-01-01

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

    2010-07-01

    Full Text Available Aspects are a natural evolution of the object-oriented paradigm. They provide a solution to some difficulties you may have encountered with modularizing your object-oriented code: sometimes functionality just doesn't fit! You've probably found yourself repeating the same lines of code in lots of different object-oriented classes because those classes each need that functionality, and so you can't easily wrap it up in a single place. Good examples of this kind of code are audit trails, transaction handling, concurrency management, and so on. You can now modularize such code with aspects. Aspect-Oriented Software Development (AOSD. Provides unique and advanced program structuring and modularization techniques. The implementation of software applications using AOSD techniques results in a better implementation structure which has an impact on many important software qualities such as enhanced reusability and reduced complexity. In turn, these software qualities lead to an improved software development lifecycle and, hence, to better software.

    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.

    CERN Document Server

    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.

    Full Text Available Requirements and their quality are very important for the success and on time delivery of a project. However, Requirement Elicitation is not an easy and small task to begin with. Conflicts arise in various ways such as way of looking at things and analyzing them, differences in expectation, mental model and many more. In many cases, clients and users are not completely sure about their actual needs in the beginning. Hence the actual solution for all such problems and conflicts is a step by step process called Requirements Engineering (RE. RE aids us in identifying, analyzing and documenting system requirements. This is an important task because it helps to eradicate mistakes and conflicts, if any, in the very early stage of development. In any approach of Software Development, RE is a very important step. Aspect Oriented Software Development is not an exception to this. Aspect Oriented Requirements Engineering (AORE helps in providing better solution by offering new methods and approaches for separation of requirements. Several AORE approaches have emerged over the years. In this paper, we try to summarise the various approaches of AORE with a brief explanation to each ofthese approaches.

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.

    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.

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

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

    Directory of Open Access Journals (Sweden)

    Seyyed Ayatollah Razmjoo

    2015-06-01

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

  2. Mediman: Object oriented programming approach for medical image analysis

    International Nuclear Information System (INIS)

    Mediman is a new image analysis package which has been developed to analyze quantitatively Positron Emission Tomography (PET) data. It is object-oriented, written in C++ and its user interface is based on InterViews on top of which new classes have been added. Mediman accesses data using external data representation or import/export mechanism which avoids data duplication. Multimodality studies are organized in a simple database which includes images, headers, color tables, lists and objects of interest (OOI's) and history files. Stored color table parameters allow to focus directly on the interesting portion of the dynamic range. Lists allow to organize the study according to modality, acquisition protocol, time and spatial properties. OOI's (points, lines and regions) are stored in absolute 3-D coordinates allowing correlation with other co-registered imaging modalities such as MRI or SPECT. OOI's have visualization properties and are organized into groups. Quantitative ROI analysis of anatomic images consists of position, distance, volume calculation on selected OOI's. An image calculator is connected to mediman. Quantitation of metabolic images is performed via profiles, sectorization, time activity curves and kinetic modeling. Mediman is menu and mouse driven, macro-commands can be registered and replayed. Its interface is customizable through a configuration file. The benefit of the object-oriented approach are discussed from a development point of view from a development point of view

It is likely that EFL (English as a foreign language students encounter various predicaments, of e.g. grasping main ideas of the dialogues in contexts, and in turn suffer from learning anxiety. The issue of how to assist the students in improving their listening competency is worth attention. This article is, therefore, intended for illustrating a test-orientated approach to teaching listening comprehension skills to EFL students through an analysis of sample questions about listening comprehension (i.e. Choosing the Right Picture, Short Questions, and Short Conversations on GEPT tests at the elementary level and through provision of tips (i.e. Skim, Scan, Listen, Guess/Infer, Choose & Write and Check on how to answer the questions effectively. Implications for teaching listening comprehension are also made at the end of the paper.

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

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

    2015-01-01

    An oriented hypergraph is a hypergraph where each vertex-edge incidence is given a label of $+1$ or $-1$. We define the adjacency, incidence and Laplacian matrices of an oriented hypergraph and study each of them. We extend several matrix results known for graphs and signed graphs to oriented hypergraphs. New matrix results that are not direct generalizations are also presented. Finally, we study a new family of matrices that contains walk information.

  7. RF control at SSCL - an object oriented design approach

    International Nuclear Information System (INIS)

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

  8. Systematic mechanism-orientated approach to chronic pancreatitis pain

    Bouwense, Stefan A.W.; de Vries, Marjan

    2015-01-01

    Pain in chronic pancreatitis (CP) shows similarities with other visceral pain syndromes (i.e., inflammatory bowel disease and esophagitis), which should thus be managed in a similar fashion. Typical causes of CP pain include increased intrapancreatic pressure, pancreatic inflammation and pancreatic/extrapancreatic complications. Unfortunately, CP pain continues to be a major clinical challenge. It is recognized that ongoing pain may induce altered central pain processing, e.g., central sensitization or pro-nociceptive pain modulation. When this is present conventional pain treatment targeting the nociceptive focus, e.g., opioid analgesia or surgical/endoscopic intervention, often fails even if technically successful. If central nervous system pain processing is altered, specific treatment targeting these changes should be instituted (e.g., gabapentinoids, ketamine or tricyclic antidepressants). Suitable tools are now available to make altered central processing visible, including quantitative sensory testing,electroencephalograpy and (functional) magnetic resonance imaging. These techniques are potentially clinically useful diagnostic tools to analyze central pain processing and thus define optimum management approaches for pain in CP and other visceral pain syndromes. The present review proposes a systematic mechanism-orientated approach to pain management in CP based on a holistic view of the mechanisms involved. Future research should address the circumstances under which central nervous system pain processing changes in CP, and how this is influenced by ongoing nociceptive input and therapies. Thus we hope to predict which patients are at risk for developing chronic pain or not responding to therapy, leading to improved treatment of chronic pain in CP and other visceral pain disorders.

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

    DEFF Research Database (Denmark)

    Bang, Anne Louise

    2011-01-01

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

  18. An object-oriented approach to evaluating multiple spectral models

    International Nuclear Information System (INIS)

    A versatile, spectroscopy analysis engine has been developed by using object-oriented design and analysis techniques coupled with an object-oriented language, C++. This engine provides the spectroscopist with the choice of several different peak shape models that are tailored to the type of spectroscopy being performed. It also allows ease of development in adapting the engine to other analytical methods requiring more complex peak fitting in the future. This results in a program that can currently be used across a wide range of spectroscopy applications and anticipates inclusion of future advances in the field. (author) 6 refs.; 1 fig

    International Nuclear Information System (INIS)

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

    2011-04-01

    An overview is given on recent progress on computing triple differential cross sections for electron-impact ionization of the hydrogen molecule using a time-dependent close-coupling approach. Our calculations, when averaged over all molecular orientations, are generally in very good agreement with (e,2e) measurements made on H2, where the molecular orientation is unknown, for a range of incident energies and outgoing electron angles and energies. In this paper, we present TDCS for ionization of H2 at specific molecular orientations. It is hoped that this study will help stimulate future measurements of TDCS from oriented H2 at medium impact energies.

    2014-08-01

    Full Text Available With growing awareness of environmental issues and firm social responsibilities, outsourcing firms increasinglyrecognize the need to be sustainability-oriented as they pursue competitiveness in the global market. However,firms are not doing this purely for altruist reasons as they still have to make a profit and account to shareholders.Therefore thispaper investigates the antecedents that push firms that adopt outsourcing initiatives to besustainability-oriented. The authors develop a model that identifies the antecedents, goals, practices, andoutcomes associated with the sustainability-outsourcing linkage. The model starts by identifying fourantecedents (regulations, supply chain demand, firm reputation, and marketplace requirements that cause ofsustainability orientation in a firm. Then, internal (i.e., product design and external (i.e., supplier managementpractices thatfirms may adopt in order to cope with their sustainability goals are introduced. Finally, the modelevaluates the impact of these practices on their outsourcing performance from the triple bottom line perspective.So this is a conceptual paper that sheds light on the role of sustainability orientation in outsourcing firms’performance, and calls for more research attention on sustainable outsourcing.

  7. The communication orientation model: explaining the diverse effects of sight, sound, and synchronicity on negotiation and group decision-making outcomes.

    Swaab, Roderick I; Galinsky, Adam D; Medvec, Victoria; Diermeier, Daniel A

    2012-02-01

    Two quantitative meta-analyses examined how the presence of visual channels, vocal channels, and synchronicity influences the quality of outcomes in negotiations and group decision making. A qualitative review of the literature found that the effects of communication channels vary widely and that existing theories do not sufficiently account for these contradictory findings. To parsimoniously encompass the full range of existing data, the authors created the communication orientation model, which proposes that the impact of communication channels is shaped by communicators' orientations to cooperate or not. Two meta-analyses-conducted separately for negotiations and decision making-provide strong support for this model. Overall, the presence of communication channels (a) increased the achievement of high-quality outcomes for communicators with a neutral orientation, (b) did not affect the outcomes for communicators with a cooperative orientation, but (c) hurt communicators' outcomes with a noncooperative orientation. Tests of cross-cultural differences in each meta-analysis further supported the model: for those with a neutral orientation, the beneficial effects of communication channels were weaker within East Asian cultures (i.e., Interdependent and therefore more predisposed towards cooperation) than within Western cultures (i.e., Independent).

    2007-01-01

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

    Outcomes assessments in clinical trials involving cognition and behavior rely upon IQ and neuropsychological assessments. These procedures provide limited evaluations of everyday functions. Some participants cannot perform cognitive tasks because they are low functioning or may represent missing data because of inability to travel. Interview-based assessments of adaptive behavior yield results that reflect everyday functions and can be done by telephone regardless of level of cognitive functioning. The design of the neurobehavioral component of the follow-up study for the management of myelomeningocele fetal surgery trial is as an example of a clinical trial that incorporates these alternatives.

    2006-07-01

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

  17. From Business Models to Service-Oriented Design: A Reference Catalog Approach

    Science.gov (United States)

    Lo, Amy; Yu, Eric

    Service-oriented architecture (SOA) is rapidly becoming the dominant paradigm for next generation information systems. It has been recognized, however, that the full benefits of SOA would not be realized unless its capabilities are exploited at the business level. In the business arena, innovations in e-business have led to the identification and classification of business models and analysis of their properties. To ease the transition from business design to service-oriented system design, we propose a reference catalog approach. Recurring business designs are collected, pre-analyzed, and documented as a set of reference business models, following a standardized template. Each reference business model is realized through a set of service-oriented design patterns. The i* framework is the basis for modeling and analysis at both the business and service design level, taking advantage of its agent orientation for modeling service relationships, and its goal orientation to facilitate adaptation from generic patterns to specific needs.

To validate the proposed model, we apply on some feature basis from the University of Carolina, Irvine Machine Learning Database.

  2. Small Firm Internet Adoption: a market oriented approach

    Directory of Open Access Journals (Sweden)

    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.

    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.

  6. Framing design research for service orientation through PSS approaches

    DEFF Research Database (Denmark)

    Sakao, Tomohiko; Sandström, Gunilla Ölundh

    2009-01-01

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

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

    International Nuclear Information System (INIS)

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

The role played by the labelling of ecologically-produced power is discussed and the economical advantages for the City of Zurich itself are examined

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

    Directory of Open Access Journals (Sweden)

    Ahmed Sharaf Eldin

    2014-08-01

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

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

    Directory of Open Access Journals (Sweden)

    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.

  12. Electron-impact ionization of oriented molecules using the time-dependent close-coupling approach

    2011-04-01

    An overview is given on recent progress on computing triple differential cross sections for electron-impact ionization of the hydrogen molecule using a time-dependent close-coupling approach. Our calculations, when averaged over all molecular orientations, are generally in very good agreement with (e,2e) measurements made on H{sub 2}, where the molecular orientation is unknown, for a range of incident energies and outgoing electron angles and energies. In this paper, we present TDCS for ionization of H{sub 2} at specific molecular orientations. It is hoped that this study will help stimulate future measurements of TDCS from oriented H{sub 2} at medium impact energies.

  13. Neurodevelopmental Outcomes Following Two Different Treatment Approaches (Early Ligation versus Selective Ligation) for Patent Ductus Arteriosus

    2012-01-01

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

  14. A Task-oriented Approach for Hydrogeological Site Characterization

    Science.gov (United States)

    Rubin, Y.; Nowak, W.; de Barros, F.

    2010-12-01

    Hydrogeological site characterization is a challenging task from several reasons: (1) the large spatial variability and scarcity of prior information render the outcome of any planned sampling campaign uncertain; (2) there are no simple tools for comparing between the many alternative measurement techniques and data acquisition strategies, and (3) physical and budgetary constraints associated with data acquisition. This paper presents several ideas on how to plan sampling campaigns in a rational manner while addressing these challenges. The first idea is to recognize that different sites and different problems require different characterization strategies. Hence the idea is to plan data acquisition according to its capability for meeting site-specific goals. For example, the characterization needs at a “research problem” site (e.g., a site intended to investigate the transport of uranium in the subsurface such as in Hanford) are different from those of a “problem” site (e.g., contaminated site associated with a health risk to human such as Camp Lejeune, or determining the safe yield of an aquifer). This distinction requires planners to define the characterization goal(s) in a quantitative manner. The second idea is to define metrics that could link specific data types and data acquisition strategies with the site-specific goals in a way that would allow planners to compare between strongly different, alternatives strategies at the design stage (even prior to data acquisition) and to modify the strategies as more data become available. To meet this goal, we developed the concept of the (comparative) information yield curve. Finally, we propose to look at site characterization from the perspective of statistical hypothesis testing, whereby data acquisition strategies could be evaluated in terms of their ability to support or refute various hypotheses made with regard to the characterization goals, and the strategies could be modified once the test is completed. Accept/reject regions for hypothesis testing can be determined based on goals determined by regulations or by agreement between the stakeholders. Hypothesis-driven design could help in minimizing the chances of making wrong decision (false positives or false negatives) with regard to the site-specific goals.

  15. Computer-oriented approach to fault-tree construction

    International Nuclear Information System (INIS)

    A methodology for systematically constructing fault trees for general complex systems is developed and applied, via the Computer Automated Tree (CAT) program, to several systems. A means of representing component behavior by decision tables is presented. The method developed allows the modeling of components with various combinations of electrical, fluid and mechanical inputs and outputs. Each component can have multiple internal failure mechanisms which combine with the states of the inputs to produce the appropriate output states. The generality of this approach allows not only the modeling of hardware, but human actions and interactions as well. A procedure for constructing and editing fault trees, either manually or by computer, is described. The techniques employed result in a complete fault tree, in standard form, suitable for analysis by current computer codes. Methods of describing the system, defining boundary conditions and specifying complex TOP events are developed in order to set up the initial configuration for which the fault tree is to be constructed. The approach used allows rapid modifications of the decision tables and systems to facilitate the analysis and comparison of various refinements and changes in the system configuration and component modeling

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

    International Nuclear Information System (INIS)

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

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

    2008-12-01

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

    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.

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

    Science.gov (United States)

    Smith, Michael R.

    1997-03-01

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

  8. Using VCL as an Aspect-Oriented Approach to Requirements Modelling

    Science.gov (United States)

    Amálio, Nuno; Kelsen, Pierre; Ma, Qin; Glodt, Christian

    Software systems are becoming larger and more complex. By tackling the modularisation of crosscutting concerns, aspect orientation draws attention to modularity as a means to address the problems of scalability, complexity and evolution in software systems development. Aspect-oriented modelling (AOM) applies aspect-orientation to the construction of models. Most existing AOM approaches are designed without a formal semantics, and use multi-view partial descriptions of behaviour. This paper presents an AOM approach based on the Visual Contract Language (VCL): a visual language for abstract and precise modelling, designed with a formal semantics, and comprising a novel approach to visual behavioural modelling based on design by contract where behavioural descriptions are total. By applying VCL to a large case study of a car-crash crisis management system, the paper demonstrates how modularity of VCL's constructs, at different levels of granularity, help to tackle complexity. In particular, it shows how VCL's package construct and its associated composition mechanisms are key in supporting separation of concerns, coarse-grained problem decomposition and aspect-orientation. The case study's modelling solution has a clear and well-defined modular structure; the backbone of this structure is a collection of packages encapsulating local solutions to concerns.

  9. A unified approach to feature-centric analysis of object-oriented software

    DEFF Research Database (Denmark)

    Olszak, Andrzej; JØrgensen, Bo NØrregaard

    2010-01-01

    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 of abstraction. We further improve scalability of analysis by partitioning features into canonical groups. To demonstrate feasibility our approach, we use our NetBeans-integrated tool Featureous for conducting a case study of feature-centric analysis of the JHotDraw project. Lastly, we discuss how Featureous supports program comprehension by means of concrete cognitive design elements.

  10. Outcome of Open Transcortical Approach in the Management of Intraventricular Lesions

    International Nuclear Information System (INIS)

    Objective: To evaluate the outcome of management of intraventricular lesions operated by an open transcortical (nonendoscopic) approach. Study Design: Case series. Place and Duration of Study: Department of Neurosurgery, Dow University of Health Sciences and Civil Hospital, Karachi, from January 2009 to December 2011, with six months follow-up. Methodology: All cases with lesions in the lateral ventricle and anterior third ventricle operated by open transcortical approach, were included after informed consent. Total excision of the lesion was attempted in all cases. Patients were analyzed for outcome in terms of establishment of diagnosis, completeness of resection, morbidity and mortality. Results: A total of 33 patients were operated. Twenty three were males and 10 were females. Colloid cyst was diagnosed in 14 patients (42%), giant cell astrocytoma and choroid plexus papilloma in 4 cases each and subependymoma and central neurocytoma in 2 cases each, epidermoid, choroid plexus carcinoma, oligodendroglioma, metastasis, meningioma, ependymoma and cavernous hemangioma in one patient each. The overall outcome could be labeled as good in 24 out of 33 cases (73%) and in 8 cases (24%) it was fair. One patient died due to ventriculitis and was categorized as poor outcome (3%). Postoperative complications included meningitis, seizures, intraventicular haemorrhage, subdural collection and transient hemiparesis. Nine patients had persistent hydrocephalus requiring ventriculoperitoneal shunt. Conclusion: Conventional open transcortical approach is still effective in getting conclusive biopsy or near total excision of the lesion with minimum morbidity. (author)

  11. Improving clinical outcomes with continuous passive motion: an interactive education approach.

    Horse, Jennifer Spotted

    2010-01-01

    Orthopaedic nursing often involves the use of equipment, and nurses may learn about the use of equipment on the job in informal ways. Staff may have difficulty attending in-services, may be off during quick informal in-services, or may not use equipment for a period of time after an in-service. Due to lack of knowledge, inconsistency in the implementation of ordered therapies resulting in poor outcomes, including pressure wounds and patient dissatisfaction, frequently occurs. Using continuous passive motion therapy as an example, an interactive educational approach to equipment training is presented. Such an approach helps formalize equipment training, provides a standard approach to implementing ordered therapy, provides references for staff after in-services, and improves patient outcomes.

    Head orientation in face-to-face interactions between mothers and infants is an important component of their communicative processes. Manual coding, however, is laborious. Obtaining inter-observer reliability is difficult, with disagreements mostly being related to the on- and offsets of a limited number of orientation categories. We used a motion capture system and developed an automated method for the quantitative measurement of infant head orientation in mother--infant face-to-face-interactions. Automated motion capture systems have the potential to objectively document not only the on- and offset of behaviors, but also continuous changes. Infants wore a cap with three reflecting markers, and eight infrared cameras captured the positions of the markers. Analytic algorithms generated continuous three-dimensional descriptions of the infants' head movements. We report here on an initial feasibility study of four infants. To evaluate the effectiveness of the automated approach, we compared it to standard manual categorical coding of six infant head orientations. We found that the central reliability issue was disagreement at the boundaries of the coding categories identified by continuous automated coding versus manual coding. The automated method was both more feasible and more precise in capturing continuous small changes. The study provides evidence for the usefulness of automated measurement of infant head orientation when infants interact in relational space. PMID:24903694

  13. A Bayesian approach for instrumental variable analysis with censored time-to-event outcome.

    Li, Gang; Lu, Xuyang

    2015-02-20

    Instrumental variable (IV) analysis has been widely used in economics, epidemiology, and other fields to estimate the causal effects of covariates on outcomes, in the presence of unobserved confounders and/or measurement errors in covariates. However, IV methods for time-to-event outcome with censored data remain underdeveloped. This paper proposes a Bayesian approach for IV analysis with censored time-to-event outcome by using a two-stage linear model. A Markov chain Monte Carlo sampling method is developed for parameter estimation for both normal and non-normal linear models with elliptically contoured error distributions. The performance of our method is examined by simulation studies. Our method largely reduces bias and greatly improves coverage probability of the estimated causal effect, compared with the method that ignores the unobserved confounders and measurement errors. We illustrate our method on the Women's Health Initiative Observational Study and the Atherosclerosis Risk in Communities Study. PMID:25393617

    People are often influenced by how persuasive appeals are framed. While decisions and preferences seem dependent on the effects of a fit between one's regulatory focus and the motivational orientation of a message, specific cognitive mechanisms involved are not yet clear. This study investigated how perceptual processing styles (global vs local) linked with the scope of attention (broad vs narrow) influence decisions depending on motivation-dependent framing (approach vs avoidance). We found that a global processing style fits approach-oriented message appeals and fosters monetary allocation toward charities framed in eager motivational terms. We discuss implications of the findings on processing styles in relation to affective versus deliberate modes of processing and the need to address in detail the role of attentional scope-dependent processing styles in decision making.

    A method is proposed for calculating alignment and orientation for open shell atoms after photoionization of an inner shell by relating the open shell dipole matrix elements to those independent of the outer open shell configuration. Thus, an extended and usually non-trivial numerical open shell approach is avoided. Our method can be applied to different configuration potentials which is illustrated by Hartree-Fock calculations of alignment and orientation which have been performed for the L{sub 3} photoionization of K, Au, Sc and Mn, and for the M{sub 5} and N{sub 7} photoionization of In and Tl, applying different numerical approaches. Dramatic effects have been found for Mn. The alignment of Au is compared to the experiment.

    Several studies found that renal transplant recipients with chronic kidney disease have untreated complications and do not attain recommended clinical targets. Using a before/after design with propensity score-matched controls, we evaluated whether an advanced practice nurse-led interprofessional collaborative chronic care approach could improve clinical outcomes for CKD transplant patients compared with a traditional physician-led model. The intervention included strategies for disease self-management, shared decision making, and healthcare system reorganization. The primary outcome was the proportion of patients attaining at least seven of nine targets as per published guidelines. A greater proportion of intervention patients achieved the outcome (68% vs. 10%; p = 0.0001) and had discussions about end-stage treatment options (88% vs. 13%; p = 0.0001) compared with controls. The intervention patients had significantly fewer emergency room visits (incidence rate ratio [IRR] 0.53; 95% CI 0.29-0.91; p = 0.02) and hospital admissions (IRR 0.34; 95% CI 0.16-0.68; p = 0.001) compared with the control patients. There were no significant differences found between the groups in systolic/diastolic blood pressure, carbon dioxide, hemoglobin, or phosphate parameters. An advanced practice nurse-led approach, based on the chronic care model, has the potential to improve clinical outcomes for renal transplant recipients and needs to be tested in a multicenter randomized controlled trial.

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

    International Nuclear Information System (INIS)

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

    2009-01-01

    This paper presents an agent-oriented approach to build a decision support system aimed at helping emergency managers to detect and to manage risks. We stress the flexibility and the adaptivity characteristics that are crucial to build a robust and efficient system, able to resolve complex problems. The system should be independent as much as possible from the subject of study. Thereby, an original approach based on a mechanism of perception, representation, characterisation and assessment is proposed. The work described here is applied on the RoboCupRescue application. Experimentations and results are provided.

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

    Directory of Open Access Journals (Sweden)

    Kleanthis C. THRAMBOULIDIS

    2003-04-01

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

  7. 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 The massive and timely delivery of media is gradually integrating itself with the dynamic composition of media-oriented services so that new types of customized media services can be created according to the diverse de- mand of end users. The resulting effective and differentiated networking support will become one of the most important requirements of the network infrastructure in the future. In this survey paper, we first present the emerging trend on the interaction of media-oriented service composition and overlay-based networks by introducing related technical issues. Then, we describe the top-down and the bottom- up approaches that coordinate service mapping using the service overlay networks (SONs and provisioning resources for them, respectively. Finally, we examine latest research on futuristic overlay networks for service realization.

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

    International Nuclear Information System (INIS)

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

  12. A Simple Regression-based Approach to Account for Survival Bias in Birth Outcomes Research.

    Science.gov (United States)

    Tchetgen Tchetgen, Eric J; Phiri, Kelesitse; Shapiro, Roger

    2015-07-01

    In perinatal epidemiology, birth outcomes such as small for gestational age (SGA) may not be observed for a pregnancy ending with a stillbirth. It is then said that SGA is truncated by stillbirth, which may give rise to survival bias when evaluating the effects on SGA of an exposure known also to influence the risk of a stillbirth. In this article, we consider the causal effects of maternal infection with human immunodeficiency virus (HIV) on the risk of SGA, in a sample of pregnant women in Botswana. We hypothesize that previously estimated effects of HIV on SGA may be understated because they fail to appropriately account for the over-representation of live births among HIV negative mothers, relative to HIV positive mothers. A simple yet novel regression-based approach is proposed to adjust effect estimates for survival bias for an outcome that is either continuous or binary. Under certain straightforward assumptions, the approach produces an estimate that may be interpreted as the survivor average causal effect of maternal HIV, which is, the average effect of maternal HIV on SGA among births that would be live irrespective of maternal HIV status. The approach is particularly appealing, because it recovers an exposure effect which is robust to survival bias, even if the association between the risk of SGA and that of a stillbirth cannot be completely explained by adjusting for observed shared risk factors. The approach also gives a formal statistical test of the null hypothesis of no survival bias in the regression framework. PMID:26011373

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

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

    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.

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

    Directory of Open Access Journals (Sweden)

    Krister P. Andersson

    2008-06-01

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

    Full Text Available Objective To explore the efficacy and safety of different surgical approaches of cervical spondylotic myelopathy, and the predictive factors for the outcome of surgery. Methods Clinical data of 68 consecutive patients who underwent surgical treatment from 2003-08-01 to 2006-12-01 were collected. The quantization of the efficacy of operation was made by applying Japanese Orthopedic Association (JOA scoring system, based on which the recovery rate and satisfaction rate were calculated. In the patients who underwent anterior approach, we compared the recovery rate among the subgroups of different duration of symptoms, age at surgery and the severity of diseases. Any surgery-related complications were also noted. Results 73.5% (50/68 patients underwent anterior approach, with an average recovery rate of (68.21 ± 10.06% and the satisfaction rate of 88.00%; 20.6% patients (14/68 underwent posterior approach, with an average recovery rate of (64.03 ± 7.07% and the satisfaction rate of 100%. The recovery rate had no significant difference in the two approaches. Only 4 patients (5.9% underwent anterior and posterior combined approach, and the recovery rate and the satisfaction rate were 65.10% and 100%, respectively. In the group of patients who accepted anterior approach, no significant differences were found in the recovery rates of different age subgroups and different duration of symptom subgroups; the significant differences recovery rates between the moderate and severe subgroups were identified. Minor complications, such as asymptomatic screw misplacement, transient dysphagia/odynophagia, pain related to the donor site and axial syndrome, were observed in a few patients. Conclusion The JOA score can be improved by applying the appropriate approaches and the high recovery and satisfaction rates can be achieved at the same time. The efficacies of anterior and posterior approaches were similar. The complications of surgery were minor. In the patients who underwent anterior approach, the severity of diseases was a predictive factor for the outcome of surgery.

    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.

  2. An Object-Oriented Modeling Approach for Collaboration Management in Virtual Enterprises

    Directory of Open Access Journals (Sweden)

    Jyhjong Lin

    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.

    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.

    This case report describes the use of the Occupational Therapy Task-Oriented Approach with a client with occupational performance limitations after a cerebral vascular accident. The Occupational Therapy Task-Oriented Approach is often suggested as a preferred neurorehabilitation intervention to improve occupational performance by optimizing motor behavior. One common critique of this approach, however, is that it may seem inappropriate or have limited application for clients with cognitive deficits. This case report demonstrates how an occupational therapist working in an inpatient rehabilitation setting used the occupational therapy task-oriented evaluation framework and treatment principles described by Mathiowetz (2004) with a person with significant cognitive limitations. This approach was effective in assisting the client in meeting her long-term goals, maximizing her participation in meaningful occupations, and successfully transitioning to home with her daughter.

    Purpose - Aims to ascertain whether a well-known theory within consumer research - a means-end chain (MEC) - can be used as a catalyst to achieve market oriented product development. Design/methodology/approach - Describes a case study, involving a Danish food manufacturer, where a MEC approach was introduced to a cross-functional development team at two different stages of the development process. Findings - Results show that MEC data is perceived as a good way of gaining knowledge about consumers; that the information serves well as the basis of discussions and for keeping project goals fixed. The resukts also indicate that MEC data are most valuable to the team in the early stages of the development process and that lack of a learning orientation may inhibit the effects of a MEC approach. Originality/value - The MEC approach shows clear advantages for market oriented product development.

    Full Text Available The notion that market orientation provides firms a source of competitive advantage seems to be widely accepted since the effects of market orientation on business performance have been extensively researched and many studies have confirmed their affirmative relationships. However, aggregated approach of market orientation as one single construct has left the detailed investigations yet unexplored despite its tremendous contribution in marketing strategy arena. Thus, decomposed properties of market orientation and their relationships with various components of firm success were explored to precisely examine the paths in this study. Furthermore, to resolve conflicting arguments on whether market orientation has a direct influence on firm level consequences, marketing mix capability was suggested as a critical mediator to complete a resource deployment system rather than a resource possession approach, which is equivalent to resource-based view. From an analysis of a survey data of 285 Korean organizations, three dimensions of market orientation, namely customer orientation, competitor orientation, and interfunctional coordination, and four sub-constructs of marketing mix capability, such as product, communication, channel and pricing capability, along with their impacts on business performance were investigated in detail. This study revealed that customer orientation and interfunctional coordination had a direct impact on only customer satisfaction while all three dimensions of market orientation failed to directly link to other firm performance variables like market effectiveness, adaptability, and profitability. To bridge these relationships product and communication capabilities were proven to be a necessary condition while channel capability and pricing capability showed interesting relationships. Findings and implications were discussed and limitations and further research directions were also suggested.

  8. Analytical Learning Based on a Meta-programming Approach for the Detection of Object-oriented Design Defects

    2012-01-01

    Full Text Available This study proposed a new defect-detection approach using a declarative meta-programming technique to analytical learning for object-oriented software. The extrapolating patterns are generated using analytical learning in which certain design defect characteristics can be understood through deductive learning. This study uses declarative meta-programming to represent the specific object-oriented components as logic rules with which design defects can finally be described. Using the two complementary techniques, the object-oriented software is transformed into the narrow related problem domain, in which design defect problems can be managed and simplified. The approach is validated by detecting design defects in certain open-source systems. The results obtained exhibit a superior precision to the conventional method. In application, the proposed strategy can be recognised as a flexible and automated system for detecting software design defects which many object-oriented software systems are able to use.

    Full Text Available Background: Segment-oriented liver resections can be performed effective by posterior intrahepatic approach. A significance of such resection is that they are oncologically radical as well as parenchyma- sparing. Methodology: Segmental liver resections were performed in 102 patients with liver tumors. Suprahilar control of the appropriate glissonean pedicle was achieved by the posterior intrahepatic approach. Liver parenchyma was transsected by ultrasonic dissector, under intermittent vascular occlusion (IVO. Pedicle was divided at the end of resection using "endo-GIA" vascular stapler. Results: The overall transection time was 30,14+12,56 min. The amount of blood loss was 285,59+129,92 ml. The postoperative complication rate was 25,49%. R0 resection had 94 (92,16% patients. There was no liver failure or perioperative death. Conclusions: Posterior intrahepatic approach for segmental resection is safe, can expedite the liver transection and reduce intraoperative hemorrhage. This approach provides adequate tumor clearance with preservation of normal parenchyma, as well as the vasculature or the biliary drainage of the contralateral liver.

    The orientation of membrane proteins undergoing fast uniaxial rotation around the bilayer normal can be determined without macroscopic alignment. We show that the motionally averaged powder spectra exhibit their 0° frequency, ?, at the same position as the peak of an aligned sample with the alignment axis parallel to the magnetic field. This equivalence is exploited to determine the orientation of a ?-sheet antimicrobial peptide not amenable to macroscopic alignment, using 13CO and 15N chemical shifts from powder spectra. This powder sample approach permits orientation determination of naturally membrane-disruptive proteins in diverse environments and under magic-angle spinning.

    We describe a minimalist approach to perform in situ decompression of the ulnar nerve. Our technique employs a unique small skin incision strategically placed to minimize postoperative scarring over the ulnar nerve and potentially decrease the risk of iatrogenic injury to the medial antebrachial cutaneous nerve. We retrospectively report the outcome of patients who have undergone this procedure at our institution, the Michael E. DeBakey Veterans Affairs Medical Center, from January 1 2007 through November 29 2010. All individuals underwent in situ decompression via the previously described minimalist approach. Outcome variables were Louisiana State University Medical Center (LSU) ulnar neuropathy grade, patient satisfaction, subjective improvement, complications and re-operation rate. A total of 44 procedures were performed in this cohort of 41 patients. Overall, patients' postoperative LSU grades showed a statistically significant improvement (p=0.0019) compared to preoperative grades. Improvement of at least one grade in the LSU scale was observed in 50% of the procedures with a preoperative grade of four or less. Overall procedure satisfaction rate was 88% (39 of 44) with 70% (31 of 44) of the procedures resulting in improvement of symptoms. There were no intraoperative or postoperative complications. One patient required re-operation due to failure of neurological improvement. Our minimalistic approach to perform in situ decompression of the ulnar nerve at the cubital tunnel is both safe and effective. We observed a statistically significant improvement in LSU ulnar neuropathy grades and a success rate comparable to those reported for other more extensive surgical techniques while providing the benefit of a smaller incision, less scarring, decreased risk of iatrogenic nerve injury and minimal complications.

    Vangsgaard, Anna Katrine; Mauricio Iglesias, Miguel

    2014-01-01

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

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

    International Nuclear Information System (INIS)

    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

    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.

  19. Change Prediction in Object-Oriented Software Systems: A Probabilistic Approach

    Ali R. Sharafat

    2008-05-01

    Full Text Available An estimation of change-proneness of parts of a software system is an active topic in the area of software engineering. Such estimates can be used to predict changes to different classes of a system from one release to the next. They can also be used to estimate and possibly reduce the effort required during the development and maintenance phase by balancing the amount of developers’ time assigned to each part of a software system. This research work proposes a novel approach to predict changes in an object-oriented software system. The rationale behind this approach is that in a well-designed software system, feature enhancement or corrective maintenance should affect a limited amount of existing code. Our goal is to quantify this aspect of quality by assessing the probability that each class will change in a future generation. Our proposed probabilistic approach uses the dependencies obtained from the UML diagrams, as well as other code metrics extracted from source code of several releases of a software system using reverse engineering techniques. These measures, combined with the change log of the software system and the expected time of next release, are used in an automated manner to predict whether a class will change in the next release of the software system. The proposed systematic approach has been evaluated on a multiversion medium sized open source project namely JFlex, the Fast Scanner Generator for Java. The obtained results indicate the simplicity and accuracy of our approach in the comparison with existing methods referred in the literature.

    Polymorphisms in genes encoding CYPs (Phase I) and ABCB1 (Phase III) enzymes may attribute to variability of efficacy of taxanes. The present study aims to find the influence of CYP and ABCB1 gene polymorphisms on taxanes based clinical outcomes. 132 breast cancer patients treated with taxanes based chemotherapy were genotyped for CYP3A4*1B, CYP3A5*3, CYP1B1*3, CYP2C8*3, ABCB1 1236C>T, 2677G>T/A and 3435C>T polymorphisms using PCR-RFLP. Associations of genetic variants with clinical outcomes in terms of response in 58 patients receiving neo-adjuvant chemotherapy (NACT), and chemo-toxicity in 132 patients were studied. Multifactor dimensionality reduction (MDR) analysis was performed to evaluate higher order gene-gene interactions with clinical outcomes. Pathological response to taxane based NACT was associated with GA genotype as well as A allele of CYP3A5*3 polymorphism (Pcorr=0.0465, Pcorr=0.0465). Similarly, association was found in dominant model of CYP3A5*3 polymorphism with responders (Pcorr=0.0465). Haplotype analysis further revealed ACYP3A4-ACYP3A5 haplotype to be significantly associated with responders (Pcorr=0.048). In assessing toxicity, significant association of variant (TT) genotype and T allele of ABCB1 2677G>T/A polymorphism, was found with 'grade 1 or no leucopenia' (Pcorr=0.0465, Pcorr=0.048). On evaluating higher order gene-gene interaction models by MDR analysis, CYP3A5*3; ABCB11236C>T and ABCB1 2677G>T/A; ABCB1 3435C>T and CYP1B1*3 showed significant association with treatment response, grade 2-4 anemia and dose delay/reduction due to neutropenia (P=0.024, P=0.004, P=0.026), respectively. Multi-analytical approaches may provide a better assessment of pharmacogenetic based treatment outcomes in breast cancer patients treated with taxanes. PMID:24704000

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

    Science.gov (United States)

    Chambers, Timothy

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

  2. A comprehensive approach to electro-orientation, electrodeformation, dielectrophoresis, and electrorotation of ellipsoidal particles and biological cells.

    Gimsa, J

    2001-08-01

    Suspended cells may respond to AC polarization by orienting, deforming, moving or rotating. For modeling of ellipsoidal cells, a new dipole approach is proposed. Along each of the principal axis of the model, three finite elements of arbitrary but equal cross-sectional area for the interior, low conductive membrane shell and exterior are assumed. The length of the external medium elements is defined by influential radii which are related to the depolarizing factors. The model predicts the potential at the ellipsoid's surface leading to the induced dipole moment. The moment obtained is identical to the Laplace approach for homogeneous ellipsoids; in the single-shell case, it is slightly different. The reason is the constant shell thickness which overcomes the confocal thickness necessary for the Laplace solution. Expressions for electro-orientation, deformation, dielectrophoresis, and electrorotation are derived. In linearly and circularly polarized fields, different orientation spectra are predicted to occur. While in linearly polarized AC fields, particles are oriented along their axis of highest polarizability, in circularly polarized fields, the axis of lowest polarizability is oriented perpendicular to the plane of field rotation. Based on this finding, a new electro-orientation method is proposed. In dielectrophoresis and electrorotation, reorientations are predicted which lead to discontinuous spectra. PMID:11506971

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

  5. Calculation of deformation rate of interstitial solid solutions under irradiation with usage of the object-oriented approach

    International Nuclear Information System (INIS)

    The creep rate is determined by streams of self point defects and mobile complexes impurity - free point defect on the dislocation. These streams are by the numerical method, if the stationary distributions of point defects in a neighbourhood of sinks are known. For solution of this composite system of the nonlinear differential equations the object-oriented approach utilized, which one represents series iterative process consisting of four stages: the analysis, designing, evolution and modification. On the basis of the object-oriented approach, the program application DefRate.exe for research of radiation creep rate is created. The application works in an operating system Windows. As all parameters are set interactive, the designed program can be easily utilized for research of the broad set of materials. The introduced object-oriented method is applicable for research of the broad set of processes controlled by the diffusion, such as the swelling and radiation creep of construction materials, the hydrogen permeability etc

    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.

    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.

    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.

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

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

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

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

    Full Text Available Modernization of legacy systems requires the existence of technicalframeworks 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 levelslinked 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 Languagecontracts 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.

    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 We are currently witnessing a decline in the development of efficient new anticancer drugs, despite the salient efforts made on all fronts of cancer drug discovery. This trend presumably relates to the substantial heterogeneity and the inherent biological complexity of cancer, which hinder drug development success. Protein-protein interactions (PPIs are key players in numerous cellular processes and aberrant interruption of this complex network provides a basis for various disease states, including cancer. Thus, it is now believed that cancer drug discovery, in addition to the design of single-targeted bioactive compounds, should also incorporate diversity-oriented synthesis (DOS and other combinatorial strategies in order to exploit the ability of multi-functional scaffolds to modulate multiple protein-protein interactions (biological hubs. Throughout the review, we highlight the chemistry driven approaches to access diversity space for the discovery of small molecules that disrupt oncogenic PPIs, namely the p53-Mdm2, Bcl-2/Bcl-xL-BH3, Myc-Max, and p53-Mdmx/Mdm2 interactions.

  17. Ontological Engineering Approach towards Trust Oriented Security Framework for Adhoc Networks

    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.

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

    Science.gov (United States)

    Himberg, Henry; Motai, Yuichi; Bradley, Arthur

    2012-06-01

    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, a new 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

    2012-12-01

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

    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

  4. Contrasting motivational orientation and evaluative coding accounts: on the need to differentiate the effectors of approach/avoidance responses

    Kozlik, Julia; Neumann, Roland; Lozo, Ljubica

    2015-01-01

    Several emotion theorists suggest that valenced stimuli automatically trigger motivational orientations and thereby facilitate corresponding behavior. Positive stimuli were thought to activate approach motivational circuits which in turn primed approach-related behavioral tendencies whereas negative stimuli were supposed to activate avoidance motivational circuits so that avoidance-related behavioral tendencies were primed (motivational orientation account). However, recent research suggests that typically observed affective stimulus–response compatibility phenomena might be entirely explained in terms of theories accounting for mechanisms of general action control instead of assuming motivational orientations to mediate the effects (evaluative coding account). In what follows, we explore to what extent this notion is applicable. We present literature suggesting that evaluative coding mechanisms indeed influence a wide variety of affective stimulus–response compatibility phenomena. However, the evaluative coding account does not seem to be sufficient to explain affective S–R compatibility effects. Instead, several studies provide clear evidence in favor of the motivational orientation account that seems to operate independently of evaluative coding mechanisms. Implications for theoretical developments and future research designs are discussed. PMID:25983718

    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.

    Introduction The past decade has been characterised by movement from a doctor-centred to a patient-centred approach to treatment outcomes, in which doctors try to see the illness through their patients’ eyes. Patients, family members and doctors are the three participants in cancer care, but their perspectives about what have been helpful during cancer treatment have never simultaneously and explicitly compared in the same qualitative study. The aim of this study project is to explore patients’ perspectives about the care they receive, as well as families’ and doctors’ perspectives about what have been helpful for the patient. These three points of view will be compared and contrasted in order to analyse the convergences and divergences in these perspectives. Methods and analysis This is a national multicentre qualitative study. Participants will be constituted by three different subsamples: (1) patients with cancer (skin, breast, urological and lung cancers), (2) their relatives, and (3) their referring physicians. Recruitment will follow the purposive sample technique, and the final sample size will be determined by data saturation. Data will be collected through open-ended semistructured interviews and independently analysed with NVivo V.10 software by three researchers according to the principles of Interpretative Phenomenological Analysis. Ethics and dissemination The research protocol received approval from the University Paris Descartes review board (IRB number: 20140600001072), and participants will provide written consent. To the best of our knowledge, this is the first study to focus on the simultaneous exploration of the separate points of view of patients, families and doctors about the care received during the cancer care journey. We expect that our findings will help to improve communication and relationships between doctors, patients and families. Comparison of these three points of view will provide information about the convergences and divergences of these perspectives and how to address the needs of all three groups.

    Full Text Available This article embraces the Sola Scriptura approach of the reformed theology. Firstly, the article focuses on the crisis in Youth Ministry, namely its inefficiency in leading young people to Christian maturity. It addressed one of the contributing factors to the crisis: the isolation of youth from the [...] adult world, and particularly from their own parents and the larger church community. From the Sola Scriptura principle, a family-orientated approach to effective Youth Ministry is proposed where parents are expected to take responsibility for their children's spiritual growth. The church should then support parents and families in this process. Different role players in a family-orientated Youth Ministry are identified and some new perceptions regarding their different tasks are proposed.

    The routine use of genomic sequencing in clinical medicine has the potential to dramatically alter patient care and medical outcomes. To fully understand the psychosocial and behavioral impact of sequencing integration into clinical practice, it is imperative that we identify the factors that influence sequencing-related decision making and patient outcomes. In an effort to develop a collaborative and conceptually grounded approach to studying sequencing adoption, members of the National Human Genome Research Institute's Clinical Sequencing Exploratory Research Consortium formed the Outcomes and Measures Working Group. Here we highlight the priority areas of investigation and psychosocial and behavioral outcomes identified by the Working Group. We also review some of the anticipated challenges to measurement in social and behavioral research related to genomic sequencing; opportunities for instrument development; and the importance of qualitative, quantitative, and mixed-method approaches. This work represents the early, shared efforts of multiple research teams as we strive to understand individuals' experiences with genomic sequencing. The resulting body of knowledge will guide recommendations for the optimal use of sequencing in clinical practice. PMID:24625446

    2005-01-01

    Broad-based community partnerships are seen as an effective way of addressing many community, health issues, but the partnership approach has had relatively limited success in producing measurable improvements in long-term health outcomes. One potential reason, among many, for this lack of success is a mismatch between the goals of the partnership, and its structure/membership. This article reports on an exploratory, empirical analysis relating the structure of partnerships to the types of is...

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

    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.

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

    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.

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

    CERN Document Server

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

    International Nuclear Information System (INIS)

    Mammography is the most effective method for breast cancer screening available today. However, the low positive predictive value of breast biopsy resulting from mammogram interpretation leads to approximately 70% unnecessary biopsies with benign outcomes. To reduce the high number of unnecessary breast biopsies, several computer-aided diagnosis (CAD) systems have been proposed in the last several years. These systems help physicians in their decision to perform a breast biopsy on a suspicious lesion seen in a mammogram or to perform a short term follow-up examination instead. We present two novel CAD approaches that both emphasize an intelligible decision process to predict breast biopsy outcomes from BI-RADS findings. An intelligible reasoning process is an important requirement for the acceptance of CAD systems by physicians. The first approach induces a global model based on decison-tree learning. The second approach is based on case-based reasoning and applies an entropic similarity measure. We have evaluated the performance of both CAD approaches on two large publicly available mammography reference databases using receiver operating characteristic (ROC) analysis, bootstrap sampling, and the ANOVA statistical significance test. Both approaches outperform the diagnosis decisions of the physicians. Hence, both systems have the potential to reduce the number of unnecessary breast biopsies in clinical practice. A comparison of the performance of the proposed decisionf 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

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

    International Nuclear Information System (INIS)

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

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

    Directory of Open Access Journals (Sweden)

    Sandra Klute

    2011-10-01

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

  13. Object-oriented approach to preequilibrium and equilibrium decays in Geant4

    International Nuclear Information System (INIS)

    The Geant4 simulation toolkit provides a set of parameterized models that allow to model hadronic showers. However, in order to allow extrapolation beyond the experimental data and to offer an alternative set of models at conventional energies, Geant4 also provides a set of theory based hadronic shower models. We present the Object Oriented Design of a semiclassical exciton model for preequilibrium decays and a set of statistical models for deexcitation of compound nuclei. Our design follows the philosophy of hadronic models in Geant4, allowing for maximum of extendibility and customizability of the underlying physics by means of the use of abstract interfaces. We exploit advanced Software Engineering techniques and Object Oriented technology to achieve those goals. We present also a series of comparisons against experimental data being made in order to test the model. (orig.)

  14. A quantum mechanical approach to establishing the magnetic field orientation from a maser Zeeman profile

    CERN Document Server

    Green, J A; Robishaw, T; Caswell, J L; McClure-Griffiths, N M

    2014-01-01

    Recent comparisons of magnetic field directions derived from maser Zeeman splitting with those derived from continuum source rotation measures have prompted new analysis of the propagation of the Zeeman split components, and the inferred field orientation. In order to do this, we first review differing electric field polarization conventions used in past studies. With these clearly and consistently defined, we then show that for a given Zeeman splitting spectrum, the magnetic field direction is fully determined and predictable on theoretical grounds: when a magnetic field is oriented away from the observer, the left-hand circular polarization is observed at higher frequency and the right-hand polarization at lower frequency. This is consistent with classical Lorentzian derivations. The consequent interpretation of recent measurements then raises the possibility of a reversal between the large-scale field (traced by rotation measures) and the small-scale field (traced by maser Zeeman splitting).

    Full Text Available Research examining the relationship between entrepreneurial orientation (EO and business performance hasrecently received considerable attention in the marketing and entrepreneurship literature. Empirical studies onthe determinants of firm performance have shown that the entrepreneurial orientation of a firm has significantpositive influence on the firm performance. However, less attention has been paid to this relationship in thecontext of SMEs. This study therefore contributes to the existing literature by examining this relationship inSMEs context. The current study suggests that the owners/ managers of SMEs should adopt the EO mindset inorder to attain sustainable competitive advantage and superior performance. The current study provides insightsto researchers, practitioners, owners and managers on the importance of the dimensions of entrepreneurialorientation.

    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.

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

    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.

    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

    Full Text Available An optimal logical topology of a wireless sensor network (WSN facilitates the deployed sensor nodes tocommunicate with each other with little overheads,lowers energy consumption, lengthens lifetime of thenetwork, provides scalability, increases reliability, and reduces latency. Designing an optimal logicaltopology for a WSN thus needs to consider numerousfactors. Chain oriented topologies have been foundto offer a number of improvements in energy consumptions, lifetime, and load balancing than othertopologies of WSNs. However, they usually suffer from latency, scalability, reliability and interferenceproblems. In this paper, we present a chain oriented logical topology, which offers solutions to thoseproblems. The proposed topology is designed such that it retains the advantages of the chain orientedtopologies, and at the same time, overcomes the problems of the chain oriented topology such as latency,scalability, and data reliability. The proposed topology provides a communication abstraction, which canbe easily used to devise a range of application protocols. Moreover, the logical topology offers nodemanagement, resource management, and other services. The performance of the proposed topology iscompared with other topologies in respect to totalenergy consumption and lifetime of the network.

  19. Orientation of human optokinetic nystagmus to gravity: a model-based approach

    Gizzi, M.; Raphan, T.; Rudolph, S.; Cohen, B.

    1994-01-01

    Optokinetic nystagmus (OKN) was induced by having subjects watch a moving display in a binocular, head-fixed apparatus. The display was composed of 3.3 degrees stripes moving at 35 degrees/s for 45 s. It subtended 88 degrees horizontally by 72 degrees vertically of the central visual field and could be oriented to rotate about axes that were upright or tilted 45 degrees or 90 degrees. The head was held upright or was tilted 45 degrees left or right on the body during stimulation. Head-horizontal (yaw axis) and head-vertical (pitch axis) components of OKN were recorded with electro-oculography (EOG). Slow phase velocity vectors were determined and compared with the axis of stimulation and the spatial vertical (gravity axis). With the head upright, the axis of eye rotation during yaw axis OKN was coincident with the stimulus axis and the spatial vertical. With the head tilted, a significant vertical component of eye velocity appeared during yaw axis stimulation. As a result the axis of eye rotation shifted from the stimulus axis toward the spatial vertical. Vertical components developed within 1-2 s of stimulus onset and persisted until the end of stimulation. In the six subjects there was a mean shift of the axis of eye rotation during yaw axis stimulation of approximately 18 degrees with the head tilted 45 degrees on the body. Oblique optokinetic stimulation with the head upright was associated with a mean shift of the axis of eye rotation toward the spatial vertical of 9.2 degrees. When the head was tilted and the same oblique stimulation was given, the axis of eye rotation rotated to the other side of the spatial vertical by 5.4 degrees. This counterrotation of the axis of eye rotation is similar to the "Muller (E) effect," in which the perception of the upright is counterrotated to the opposite side of the spatial vertical when subjects are tilted in darkness. The data were simulated by a model of OKN with a "direct" and "indirect" pathway. It was assumed that the direct visual pathway is oriented in a body, not a spatial frame of reference. Despite the short optokinetic after-nystagmus time constants, strong horizontal to vertical cross-coupling could be produced if the horizontal and vertical time constants were in proper ratio and there were no suppression of nystagmus in directions orthogonal to the stimulus direction. The model demonstrates that the spatial orientation of OKN can be achieved by restructuring the system matrix of velocity storage. We conclude that an important function of velocity storage is to orient slow-phase velocity toward the spatial vertical during movement in a terrestrial environment.

    For various reasons, Archaeoastronomy has not been one of the favourite disciplines of the Egyptologists in the past. Probably because of that, important questions such as the orientation of Egyptian temples and the relevance of astronomy in this respect had never been afforded with the necessary seriousness and deepness. The Egyptian-Spanish Mission for the Archaeoastronomy of ancient Egypt has, among its various priorities, the solution of this problem. In order to achieve that, we have measured the orientation of some 330 temples in the Valley, the Delta, the Oases and the Sinai so far. The aim is to find a correct and almost definitive answer to the question of whether the ancient Egyptian sacred constructions were astronomically aligned or not. Our data seem to answer this question in the affirmative sense. Besides, they offer a very interesting new perspective in the field of landscape archaeology, a new discipline hardly worked in Egypt so far, in which terrestrial landscape, dominated by the Nile, and celestial landscape, dominated by the sun and the stars, would combine in order to permit the establishment of Ma’at, the Cosmic Order, on Earth.

  1. Product Lines' Feature-Oriented Engineering for Reuse: A Formal Approach

    Marcel Fouda Ndjodo

    2010-09-01

    Full Text Available The feature oriented method with business component semantics (FORM/BCS is an extension of the feature oriented reuse method (FORM developed at Pohan University of Science and Technology in South Korea. It consists of two engineering processes: a horizontal engineering process driven by the FORM domain engineering process and a vertical engineering process driven by the FORM application engineering process. This paper investigates the horizontal engineering process - which consists of analyzing a product line and developing reusable architectures - and shows that this process can be systematized through a set of maps that describe how one can systematically and rigorously derive the fundamental business architectures of a product line from the feature model of that domain. The main result of the paper is therefore that the formalization of the assets of FORM/BCS enables a clear definition of how an activity of the horizontal engineering process produces a target asset from an input one. This result opens the door for the development of a tool supporting the method.

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

  3. A population approach to cortical dynamics with an application to orientation tuning.

    A typical functional region in cortex contains thousands of neurons, therefore direct neuronal simulation of the dynamics of such a region necessarily involves massive computation. A recent efficient alternative formulation is in terms of kinetic equations that describe the collective activity of the whole population of similar neurons. A previous paper has shown that these equations produce results that agree well with detailed direct simulations. Here we illustrate the power of this new technique by applying it to the investigation of the effect of recurrent connections upon the dynamics of orientation tuning in the visual cortex. Our equations express the kinetic counterpart of the hypercolumn model from which Somers et al (Somers D, Nelson S and Sur M 1995 J. Neurosci. 15 5448-65) computed steady-state cortical responses to static stimuli by direct simulation. We confirm their static results. Our method presents the opportunity to simulate the data-intensive dynamical experiments of Ringach et al (Ringach D, Hawken M and Shapley R 1997 Nature 387 281-4), in which 60 randomly oriented stimuli were presented each second for 15 min, to gather adequate statistics of responses to multiple presentations. Without readjustment of the previously defined parameters. our simulations yield substantial agreement with the experimental results. Our calculations suggest that differences in the experimental dynamical responses of cells in different cortical layers originate from differences in their recurrent connections with other cells. Thus our method of efficient simulation furnishes a variety of information that is not available from experiment alone. PMID:11128166

    2014-09-01

    The use of questionnaires to measure two facets of mindfulness, 'regulation of attention' and 'non-judgmental orientation,' has been criticized. Furthermore, the assumption that depressed individuals show deficits in both facets has not yet been proven. In an attempt to minimize several biases associated with mindfulness questionnaires, we asked 43 currently depressed and 36 never-depressed participants to observe their breathing. The 'regulation of attention' facet of mindfulness was measured by the number of times participants' focus drifted off of their breathing. The 'non-judgmental orientation' facet was assessed using skin conductance response (SCR) and corrugator activity measured by electromyography (EMG), as indicators associated with arousal and negative emotions following drifting, and also by a self-report questionnaire. Depressed patients showed deficits in both facets of mindfulness. Specifically, compared to never-depressed controls, depressed patients drifted focus from their breathing more often, had significantly higher self-reported self-criticism, and displayed an increase in corrugator activity after drifting from breathing.

    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.

    2014-01-01

    Full Text Available This paper has proposed novel weaving mechanism for Graph ? semantic based Aspect Model called GAM. The GAM provides formal representation of Aspect Oriented System (AOS concepts like join points, advices, PointCut etc. using graph based semantics. Moreover, GAM facilitates the aspect algebra which is comprised of set of operators defined on conceptual semantics of GAM. Those operators are used to conceptualize the different operations of cross cutting concerns in AOS design and also play a crucial role on realization of proposed weaving mechanism formally at model level. The proposed model level weaving mechanism is also capable to handle the cross-cutting issues related to static weaving, dynamic weaving and conflicts handling. The paper also demonstrates the expressiveness of the crosscutting operators of aspect algebra using several interesting properties in the context of AOS.

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

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

    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...

    2010-10-01

    Full Text Available In the content filtering-based personalized recommender systems, most of the existing approaches concentrate on finding out similarities between users’ profiles and product items under the situations where a user usually plays a single role and his/her interests persist identical on long term basis. The existing approaches argue to resolve the issues of cold-start significantly while achieving an adequate level of personalized recommendation accuracy by measuring precision and recall. However, we investigated that the existing approaches have not been significantly applied in the context where a user may play multiple roles in a system simultaneously or may change his/her role overtime in order to navigate the resources in distinct authorized domains. The example of such systems is enterprise architecture management systems, or e-Commerce applications. In the scenario of existing approaches, the users need to create very different profiles (preferences and interests based on their multiple /changing roles; if not, then their previous information is either lost or not utilized. Consequently, the problem of cold-start appears once again as well as the precision and recall accuracy is affected negatively. In order to resolve this issue, we propose an ontology-driven Domain-based Filtering (DBF approach focusing on the way users’ profiles are obtained and maintained over time. We performed a number of experiments by considering enterprise architecture management aspect and observed that our approach performs better compared with existing content filtering-based techniques.

    Full Text Available Abstract Background To present a diagnostic evaluation and treatment strategy for serous adenocarcinoma of the ovary discovered during an in vitro fertilisation (IVF sequence, and report on reproductive outcome after tumour resection and embryo transfer. Case presentation Cycle monitoring in IVF identified an abnormal ovarian lesion which was subjected to ultrasound-guided needle aspiration. Cytology suggested malignancy, and unilateral oophorectomy was performed after formal staging. After surgery, the patient underwent an anonymous donor oocyte IVF cycle which established a viable twin intrauterine pregnancy. No recurrence of cancer has been detected in the >72 month follow-up interval; mother and twin daughters continue to do well. Conclusion Suspicious adnexal structures noted during controlled ovarian hyperstimulation for IVF warrant assessment, and this report confirms the role of aspiration cytology in such cases. If uterine conservation is possible, successful livebirth can be achieved from IVF if donor oocyes are utilised, as described here.

  13. Toward a domain-specific approach to the study of parental psychological control: distinguishing between dependency-oriented and achievement-oriented psychological control.

    Science.gov (United States)

    Soenens, Bart; Vansteenkiste, Maarten; Luyten, Patrick

    2010-02-01

    Theory and research suggest that psychologically controlling parenting can be driven by parental concerns in two different domains, that is, interpersonal closeness and achievement. Three studies addressing this hypothesis are presented. Study 1 provides evidence for the validity of the Dependency-Oriented and Achievement-Oriented Psychological Control Scale (DAPCS), a new measure assessing psychological control in these two domains. Study 2 showed that dependency-oriented and achievement-oriented psychological control were related in expected ways to parental separation anxiety and perfectionism in a sample of mothers and fathers. Finally, Study 3 showed that dependency-oriented and achievement-oriented psychological control were differentially related to middle adolescent dependency and self-criticism and that these personality features act as specific intervening variables between the domain-specific expressions of psychological control and depressive symptoms. It is argued that the distinction between two domain-specific expressions of psychological control may allow for a more intricate analysis of the processes involved in intrusive parenting.

    DEFF Research Database (Denmark)

    Jensen, Jesper Ole; Gram-Hanssen, Kirsten

    2004-01-01

    Gram-Hanssen and Jensen explore the development of green buildings in Denmark over the last three decades, identifying differences in design philosophies and techniques. They look at four approaches to green buildings: as energy-saving devices, as ecological grassroots alternatives, as subsidised large-scale urban projects, and as consumer products in a market approach. Using detailed case descriptions, the chapter asks to what extent it is possible to define some buildings or some approaches as more 'green' than others. The authors suggest that in order to more fully understand sustainable buildings we must account for the social structuring of both the identification of environmental problems and their resulting embodiment in built form.

    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.

    The Global Hydrology Resource Center (GHRC), a NASA Earth Science data center managed by the University of Alabama in Huntsville, is one of twelve data centers that make up the Distributed Active Archive Centers (DAAC) Alliance. Over the years, GHRC staff have developed and evolved a production information management infrastructure to ingest, inventory, archive and distribute a variety of data products to our users. The GHRC has also collaborated with Remote Sensing Systems (RSS) over the course of three NASA Earth Science programs (ESIP, REaSON, and now MEaSURES) to develop valuable Earth science products and services, specifically for passive microwave sensors. This continued effort, known as the DISCOVER (Distributed Information Services for Climate and Ocean products and Visualizations for Earth Research) project, has been able to explore more experimental data services. A result of this collaboration is that services developed and hardened in the DISCOVER service oriented architecture may be integrated into the baseline GHRC infrastructure. For example, the GHRC Data Pool was originally developed for DISCOVER and is now supporting the inventory, search and distribution of science data products across multiple GHRC and DISCOVER data repositories. Distributed services for harvesting metadata and packaging data orders interoperate with two complementary search/access/order user interfaces through a central metadata and order tracking database. This presentation will discuss the science data tools and services developed by DISCOVER and the GHRC, with a focus on integration of new services into an established data management infrastructure.

  1. Product Service Systems and Non-Market Oriented Approach – Methodological and Ethical Considerations from a Design Perspective

    2008-01-01

    Macroscopic social and economic changes in the last few years are forcing business companies and public institutions to redefine their approach to social intervention, focusing on local and highly individualised solutions. This change is also calling for a new design approach. The challenge for designers is not only to be able to provide local and highly individualised solutions, but also to propose strategies to transfer and reproduce the solutions, or part of them, into different local contexts, thus creating economy of scope. This would be possible by using forms of codification and modularisation of the most relevant components in local solutions. The code refers to the organisational knowledge included in local components and the way each component interacts with the others. Like software systems, local product-service systems can be built upon a source code. This paper will illustrate how this process was developed in a concrete case. Through this case the authors analyse the possibility to build something similar to a source code for initiatives based on social interaction and investigate the process of construction of such a code Furthermore, the author discuss differences and analogies between design intervention in a social context and in the normal business context. The question of codification suggests a methodological approach for supporting transferability both in the problem space (dealing with complexity) and in the solution space (dealing with contingency). The analysis of differences and similarities between business- and socially-oriented processes suggests a new role for designers and new opportunities for innovation.

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

    International Nuclear Information System (INIS)

    Purpose: To retrospectively compare immediate and long-term outcome of central venous infusion port inserted via right high versus low jugular vein approaches. Materials and methods: The study included 163 patients (125 women patients, 38 men patients; age range, 18-79 years; mean age, 53 years); 142 patients underwent port insertion with low jugular vein approach and 21 patients with high jugular vein approach. The causes of high jugular vein puncture were metastatic lymphadenopathy (n = 7), operation scar (n = 6), radiation scar (n = 5), failure of low jugular vein puncture (n = 2), and abnormal course of right subclavian artery (n = 1). Medical records and radiologic studies were reviewed retrospectively to determine and compare the outcome and the occurrence of complication related to port. Results: The procedure-related complications were all minor (n = 14, 8.6%) in both groups; hematoma (n = 4, 2.8% in low jugular puncture group and n = 1, 4.8% in high jugular puncture group, p = 0.6295), air embolism (n = 2, 1.4% in low jugular puncture group and n = 0 in high jugular puncture group, p = 0.5842) and minor bleeding (n = 5, 3.5% in low jugular vein puncture group and n = 2, 9.5% in high jugular vein puncture group, p = 0.2054). The average length of follow-up was 431 days for low jugular vein puncture group and 284 days for high jugular vein puncture group. The difference between two groups was significant (p = 0.0349). The reasons for catheter removal were patiehe 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.

    Health care systems throughout the world are faced with continuously rising health care expenditure. In Germany, a fee per capita system will be introduced by 2003 to keep the budgets for hospital care within limits. As a result, numbers of hospital beds and hospitals will be cut in the coming years. On the other hand, more and more patients and health care providers are asking if they are really receiving an adequate value for their money in the treatment they receive. All this will have a strong impact on the anaesthesiologist's work and her/his perception of the different facets of quality. Quality has various aspects for the anaesthesiologist. The patient as a customer should not incur any detrimental effects after a surgical procedure, and is accompanied by the anaesthesiologist throughout the perioperative setting. The surgeon needs optimal conditions to perform a procedure. The hospital must balance equally costs and income; this requires optimal operating room utilization. Finally, health insurance companies and the government are responsible for covering the cost of treatment according to the quality of the care delivered. Quality assessment concerning structure, process and outcome has to take these demands into account. Continuous quality improvement in the spirit of Deming's 'plan-do-check-act cycle' has to be part of anaesthesiologist's everyday routine. In future, the traditional barriers between the specialities treating a patient will be disrupted when reimbursement for treatment is made according to quality and efficacy of treatment.

    Full Text Available It is a bitter reality that the curricula and traditional pedagogy prevailing in public schools of Pakistan in general and Sindh in particular do not incorporate the algebraic concepts properly. Both the content and the presentation therein cannot be considered up to the mark, thereby making “Algebra” a tough and dry subject. This quasi-experimental study focused to find out the effect of teaching algebra through social constructivism on the students learning outcomes of 7th graders in public schools of District Jamshoro Sindh. For this purpose two existing in-tact sections of grade 7 (7th A, and 7th B of a government high school of district Jamshoro were selected as quasi control and treatment groups. The pre and posttest analyses were carried out. The first pattern t-test analysis revealed that both groups were parallel, however, the latter posttest analysis revealed that treatment group that was taught through social constructivist approach excelled in achieving statistically significant learning outcomes than that of control group that was taught through traditional one-way teaching.

    Full Text Available This paper aims at developing an applied system to evaluate the e-Learning Modules (eLMs depending on selected related criteria. Those criteria concern with many fields as well as many factors like, learning theories, computer science, instructional computer, software engineering, educational sciences, language criteria, economical factors, etc. Therefore the authors expressed the term of selected criteria to reflect the meaning of integrated factors of the environment deals with the developed eLM. However eLM for any subject requires for a systematic steps of integrated work depending on the model which is considered by the developer. Mostly the output of a stage represents the input of the next step. Our model will cover all steps in details. Thus such model could be considered not only to evaluate the developed eLMs but it could be used during process of developing because many items of criteria are designed so as to be a guide for developer during development of eLM. Developer should consider eLMs while he/she develops an eLM. Finally the authors presented selected eLM to apply the evaluating model, outcomes of the evaluations process lead to the needful conclusion.

    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...

    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.

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

    Science.gov (United States)

    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.

    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.

    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.

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

    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. Binarisms, regressive outcomes and biases in the drug policy interventions: a theoretical approach.

    The golden age of drug policy was characterized by the informal regulation of drug use. Formalization of the control over regulation and its increasingly strict, aggressive character led to the emergence of a binary attitude. The main binarisms: pharmaceutical or drug; ban or tolerance; punishment or treatment; psychopathological or pathopsychological approach; subjective or objective knowledge; traditional or alternative. On the basis of Kuhn's paradigm theory, these binarisms can be integrated. Drug policy interventions based on the binary attitude have had regressive effects. Using the work of Sam Sieber, the author distinguishes nine regressive influences: functional imbalance, perverse diagnosis, ricochet, overload, goal displacement, exploitation, provocation, classification, and placation. The regressive influences have caused the escalation of "the drug problem," which in turn has led to further regressive interventions. This vicious circle could be broken by eliminating the four biases--the paternalistic, elitist, rationalist, and activist biases--underlying the regressive interventions. PMID:15830729

    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.

    Delivering on the promise of personalized medicine has become a focus of the pharmaceutical industry as the era of the blockbuster drug is fading. Central to realizing this promise is the need for improved analytical strategies for effectively integrating information across various biological assays (for example, copy number variation and targeted protein expression) toward identification of a treatment-specific subgroup-identifying the right patients. We propose a novel combination of elastic net followed by a maximal ?(2) and semiparametric bootstrap. The combined approaches are presented in a two-stage strategy that estimates patient-specific multi-marker molecular signatures (MMMS) to identify and directly test for a biomarker-driven subgroup with enhanced treatment effect. This flexible strategy provides for incorporation of business-specific needs, such as confining the search space to a subgroup size that is commercially viable, ultimately resulting in actionable information for use in empirically based decision making.

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

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

    International Nuclear Information System (INIS)

    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.

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

    International Nuclear Information System (INIS)

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

    Full Text Available 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.

    2011-11-01

    In recent years, the wide-spreading of vineyard cultivation in the Apulia Region, Italy) has showed negative consequences on the hydrogeological balance of soils as well as on the visual quality of rural landscape which has been significantly altered by the heavy diffusion of artificial plastic coverings. In order to monitor and manage this phenomenon, a detailed site mapping has become essential. With the increase of spatial resolution, pixel based approaches no longer capture the characteristics of classification targets. Consequently, classification accuracy is poor. Object-based image classification techniques overcome this issue by first segmenting the image into meaningful multipixel objects of various sizes and then assigning segments to classes using fuzzy methods and hierarchical decision keys. In this study an object-based classification procedure from Very High Spatial Resolution (VHSR) true color aerial data was developed on a test area located between the Apulian municipalities of Ginosa and Palagiano in order to support the update of the existing land use database aimed at plastic covered vineyard monitoring.

    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.

  16. 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

  17. A System-Oriented Approach for the Optimal Control of Process Chains under Stochastic Influences

    2011-09-01

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

    Patients affected by vestibular schwannomas typically report a number of symptoms and minor disabilities after surgery. Therefore, surgeons dealing with this pathology should also try to achieve a good QoL for patients who have undergone tumour removal. The aim of this study was to analyse QoL in subjects undergoing surgery for vestibular schwannomas and to try to establish a relationship with both the tumour size and post-surgical alterations (e.g. facial motor dysfunctions, difficulties in balance, persistence of headache and tinnitus). A retrospective analysis was performed on a consecutive series of 81 patients affected by vestibular schwannomas and treated by a combined microscopic-endoscopic approach. Three groups of patients were identified on the basis of tumour size. Group 1 (lesions 26 mm and 41 mm) with 11 patients (14%). Data obtained with the Short Form Questionnaire showed a statistically significant difference in QoL in those undergoing intervention compared with a control group of healthy subjects. The Glasgow Benefit Inventory Questionnaire showed that 25 (31%) patients felt better, 11 (14%) felt similarly, and 45 (55%) felt poorer health conditions in comparison to the pre-surgical period. Concerning the relationship between preservation of facial nerve function and QoL, using the Glasgow Health Status Inventory, it appeared that only 34% of subjects with good facial nerve function (RGS grade I-II) complained of worsening of QoL, while 45% of those with serious facial nerve injury (RGS grade IV-V) referred poorer QoL. Moreover, the possibility of recovery of facial nerve function during the months following surgery was clearly highlighted by our analysis. Our study confirmed the close relation between tumour size and post-surgical QoL, which is worse for patients affected by larger lesions. PMID:25762836

    2013-01-01

    In this paper we present different strategies to integrate concerns about sustainability into Information and Communication Technology (ITC) projects by use of problem based learning (PBL) methodology. In alignment with PBL we introduce two different models for problem analysis where students move from a broader theme to a problem formulation designed to fit the time, discipline and theme of study. In the prospect of Education for Sustainable development (ESD) the students are to move from the conceptually complex field of sustainable development (SD) to a specific formulation of a problem that initiate design, implementation and test of ICT for SD. On the empirical level we draw from experiments in autumn 2009 and spring 2013 within the field of Media technology. Observations, text analysis of students’ work as well as reflections from staff has been relied on in order to analyse the practical implications of the different approaches to integrate sustainability. We conclude that students indeed chose divers strategies to integrate sustainability into their projects and those diverse strategies are indeed needed to obtain student engagement. Furthermore, the introduction of an open-ended thematic frame, like sustainability, encouraged students to broaden their perspective on stressing economic, environmental as well as social concerns. However, the experiments also showed that interlinking engineering subjects with sustainability is a rather time-consuming task – and some of the students were struggling with these open-ended themes at the same time as they were struggling with the rather open-ended perspectives on how to manage and structure a problem based and project organised project.

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

    2014-12-01

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

    Biogeochemical models used for simulating greenhouse gas (GHG) emissions are mainly designed for the plot scale. Lateral fluxes of nutrients such as nitrate, which may be important drivers for soil GHG emissions, are not or only scarcely considered and explored in such models. This is due to the complexity of microbiological, physic-chemical and plant processes which need to be investigated and simulated along one spatial dimension, the depth, so that the introduction of a second (a hillslope) or third (entire landscapes) spatial dimension is likely to introduce additional complexity which can hardly be handled by most models. However, plot scale models, validated with data obtained at plot scale studies, will systematically under- or overestimate key GHG production and consumption processes if lateral in- or efflux of nutrients to or from a given site is of significant importance. E.g. in laterally connected environments, such as riparian zones denitrification will be fuelled by lateral influx of nitrate from uphill positioned fertilized land. Thus, landscape approaches are needed to identify and realistically simulate GHG emissions. The poster will present a coupled modeling system consisting of the fully distributed hydrology model CMF coupled to the regional ecosystem model LandscapeDNDC. The model coupling was preformed using the OpenPALM coupler from Cerfacs, France which is based on parallel computer technology. The coupler synchronizes the two models with respect to simulation time and performs the exchange of data (water fluxes, nutrient concentrations, etc.) from and to the models. The resulting coupled hydrology-ecosystem model was applied to simulate carbon and nitrogen cycling along a three dimensional virtual hillslope. In the experiment the uphill section of the domain consists of intensive arable land (maize - wheat rotation with up to 300 kg N fertilization) whereas the lowland section and riparian zone consists of extensive grassland. The simulation results show the effect of lateral nutrient transport (nitrate) along the hillslope leading to biomass productivity gradients in the extensive grassland towards the riparian zone associated with high indirect N2O emissions, specially in the riparian zone. Simulation of N cycling with the coupled hydrology - ecosystem model along a hillslope consisting of up to 30 grid cells. N fertilizer added upland will be converted into nitrate leading to biomass production and nutrient transport along the hillslope as well as N2O emissions.

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

    Dan Cristian DABIJA

    2013-11-01

    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.

    Full Text Available In view of the fact that supply strategies alone could not solve urban congestion, many cities around the globe have adopted Transport Demand Management (TDM strategies as part and partial of their congestion mitigation plan. TDM comprises several strategies and policies that aim to modifying travelers’ behaviour. TDM comprises strategies and policies that are different in nature which can be divided into several categories according to how they affect travelers’ behavior. Selecting and determining suitable TDM strategies for a particular congestion mitigation goal can be a complex task; thus requires expertise. In this regards, the effectiveness of a TDM strategy is primarily depending on whether its selection was appropriately examined prior to its field implementation. This paper presents the development of an expert system shell for TDM. The process of organizing the available knowledge of TDM strategies, as well as the process leading to the selection of one or more strategy advice, is encoded in the knowledge based expert system shell developed for the purpose by using shell expert system Kappa-PC version 2.4 which was adopted object oriented approach and high resolution graphical user interface. The advice given from the working system was evaluated and validated by comparing the output of the system against the recommendations made by transportation professionals. The evaluations indicate favourable results for the system. The expert advisory system can be used as a decision support system as well as a teaching tool for junior transportation engineers, planners, private developers, and government officials.

    2014-02-01

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

    Thousands of refugees from around the world resettle in the United States every year. Many refugees suffer from mental health disorders as a result of experiences living in or escaping from their turbulent homelands, and many also experience mental health issues as they settle in their new host countries. As such, it is important to intervene during the early stages of refugee resettlement to help prevent or mitigate mental illness symptoms. However, because of several access and utilization barriers, such as stigma, refugees are not apt to receive needed mental health services. Moreover, the traditional Western model of treatment can be culturally incongruent with refugee practices. Alternative, culturally sensitive, community-based approaches must be considered. This article presents a community-oriented prevention and early intervention model that can be used with newly arrived refugees with limited English proficiency. Goals of the model are to increase knowledge of mental health and mental health service options to refugees, as well as support the process of adjusting to life in the United States. The New Refugee Services Project, developed by the Center for Survivors of Torture department of Asian Americans for Community Involvement (AACI) in San Santa Clara County, California is presented as an example case study. The structure outlined in this article aims to support the development, implementation, and assessment of future preventative interventions for refugee populations. PMID:25384000

    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

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

    International Nuclear Information System (INIS)

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

      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

    Parental knowledge is a key protective factor for youths' risky behavior. Little is known about how longitudinal combinations of knowledge-related behaviors are associated with youths' substance use. This longitudinal study uses Latent Transition Analysis to identify latent patterns of parental knowledge-related behaviors occurring in mother-youth dyads during middle school and to investigate how changes in knowledge-related patterns are associated with youths' substance use in Grade 6 and the initiation of substance use from Grade 6 to 8. Using a sample of 536 rural dyads (53 % female, 84 % White), we assessed mother and youths' reports of parental knowledge, active parental monitoring efforts, youth disclosure, and parent-youth communication to identify six latent patterns of knowledge-related behaviors: High Monitors, Low Monitors, Communication-Focused, Supervision-Focused, Maternal Over-Estimators, and Youth Over-Estimators. Fifty percent or more of dyads in the High Monitors, Communication-Focused and Youth Over-Estimators were in the same status in both 6th and 8th grade: 98 % of Low Monitors in Grade 6 were also in this status in Grade 8. The initiation of alcohol, smoking, and marijuana was associated significantly with transitions between patterns of knowledge-related behaviors. The initiation of alcohol and smoking were associated with increased odds of transitions into the Low Monitors from the Communication-Focused, Supervision-Focused, and Maternal Over-Estimators. However, the initiation of substance use was associated with decreased odds of transitions from the High Monitors to the Low Monitors and with increased odds of transitions from High Monitors to Supervision-Focused. The discussion focuses on the value of using a person-oriented dyadic approach with multiple reporters to study changes in knowledge-related behaviors over the middle school period. PMID:23996214

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

    2015-04-01

    The effects of religiosity on well-being appear to depend on religious orientation, with intrinsic orientation being related to positive outcomes and extrinsic orientation being related to neutral or negative outcomes. It is not clear, however, why intrinsic and extrinsic religiosity has the relationships they do. Self-determination theory may provide a useful framework of intrinsic and extrinsic aspirations that may help to answer this question. The purpose of the present study was to examine whether intrinsic and extrinsic religiosity would be related to intrinsic and extrinsic life aspirations. We hypothesized that intrinsic religiosity would be positively related to intrinsic life aspirations and negatively related with extrinsic life aspirations, and that extrinsic religiosity would be positively related to extrinsic life aspirations and negatively related to intrinsic aspirations, and that life aspirations would partially mediate the relationships between religious orientation and outcome. To study these hypotheses, a random national sample (total number of 425, average age of 52, 59 % female) completed the measures of religious orientation, life aspirations, affect, and life satisfaction. It was found that intrinsic religiosity was positively related to positive affect, life satisfaction, and intrinsic life aspirations and was negatively related to negative affect and extrinsic life aspirations. Extrinsic religiosity was positively related to extrinsic life aspirations and was not related to the intrinsic life aspirations. When both religious orientation and life aspiration variables were included together in the model predicting outcome, both remained significant indicating that religious orientation and life aspirations are independent predictors of outcome. In conclusion, although religious orientation and life aspirations are significantly related to each other and to outcome, life aspirations did not mediate the effects of religious orientation. Therefore, self-determination theory does not appear to completely account for the effects of religious orientation. PMID:24474550

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

    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

    2013-06-01

    Full Text Available Aspect Oriented Programming methodology is based on the idea that computer systems can be programmed very efficiently by specifying the various concerns of a system and some description of their relationships separately and then relying the mechanisms in the underlying AOP environment to weave them together into a coherent program automatically. The term Aspect Oriented Programming includes Multidimensional Separation of Concerns, along with Subject Oriented Programming, Adaptive Programming and Composition Filters. Multidimensional Separation of Concerns (MDSOC permits the encapsulation of various kinds of concerns simultaneously and the integration of separate concerns. The Aspect.NET Framework is implemented as an add-in to visual studio.NET. Now, the user can use Aspect.NET in combination to the integration development environment provided by Visual Studio.NET and all its various features for the development of software applications using AOP methodology.

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

    Scientific Electronic Library Online (English)

    Daleen, Casteleijn; Margot, Graham.

    Full Text Available Occupational therapists use a client-centered approach as part of embracing a philosophy of respect for, and partnership with people receiving services. This approach must also be incorporated in measuring outcomes of the service and clients must have input in evaluating the outcomes of their interv [...] ention. This article reports on a specific phase of a larger study in which clients have been included in confirming the domains for an outcome measure in occupational therapy in mental health care settings. A case study strategy was used which enabled mental health care users to express their needs and expectations of the occupational therapy service. These were captured during 12 individual interviews and two focus groups. The findings were thematically analysed and constantly compared with the domains identified by occupational therapy clinicians in Phase 1 of the larger study. Results from this study indicated that the service which the participating occupational therapy clinicians were rendering, were in keeping with the needs and expectations of the mental health care users.

    Spigarelli, Michael G

    2007-12-01

    Sexual orientation has been defined as the patterns of sexual thoughts, fantasies, and attractions that an individual has toward other persons of the same or opposite gender. Throughout childhood and approaching adolescence, children try to understand their own sexuality and sexual orientation in the context of the society in which they live. Typically, this attempt to understand first occurs in thoughts of a sexual nature and later through actions, usually before sexual orientation is clearly defined. How these experiences are handled, by the individual and close friends and relatives, helps to define how an individual views and accepts their sexual orientation ultimately as an adult.

    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.

    The single-crystal rotation technique was applied to magnetically oriented microcrystal arrays (MOMAs) of cellobiose (monoclinic) to determine the principal values and principal axes of the chemical shift tensors of C1 and C1? carbons. Rotations were performed about the magnetic ?1, ?2, and ?3 axes of MOMA, and the measurements were taken at six different orientations with respect to the applied magnetic field. Under these rotations, crowded peaks were reduced and the peaks for the C1 and C1? carbons were identified by comparing with simulation results. Six components of the chemical shift tensor expressed with respect to the magnetic ?1?2?3-frame were determined. The tensors thus obtained were transformed into those relative to the molecular frame.

    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.

    To evaluate professionals' attitudes to recovery and coercion, as well their satisfaction with working conditions before and after the implementation of a recovery-oriented ward concept on an admission ward. Longitudinal study design with two measurement times of the study sample, with a control group assessed at study end. Evaluating the implementation of the recovery concept, attitudes towards recovery, coercion, perceptions of the ward and working satisfaction were assessed with questionnaires and computed using Chi square and ANOVA variance analyses. The members of the intervention ward (n = 17) did not differ from the control group (n = 21), except that control group members were younger. The recovery-orientation of the study ward (ROSE questionnaire) increased significantly (alpha level = 0.05) from study begin to study end (p = 0.003), and compared to the control group (p = 0.002). The attitudes towards coercion did not change significantly in the intervention group, but did so compared to the control group. The contentedness (GMI) and the satisfaction with working conditions (ABB) of the intervention group members compared to control group was significantly higher (GMI: p = 0.004, ABB subscale working conditions: p = 0.043, satisfaction: p = 0.023). The study indicates that recovery-oriented principles can be implemented even in an acute admission ward, increasing team satisfaction with work, while attitudes towards coercion did not change significantly within this single-unit project.

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

    Science.gov (United States)

    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

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

    International Nuclear Information System (INIS)

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

    Methodological and statistical challenges have been identified in family research when the parental dyad is under study. The purposes of this article are to review the literature on methodological and statistical procedures in research on families, and to introduce an analysis technique that is new to the nursing literature, the actor-partner interdependence model (APIM). The use and interpretation of the APIM method is illustrated through an example of families of young children with asthma. In the APIM an actor effect is the impact a person has on his or her own outcome, whereas a partner effect is the impact a member of a dyad has on his or her partner's outcome. The main findings from the data example indicate that family adaptation is influenced by the actor effect of resiliency factors (sense of coherence and family hardiness), the partner effect of caregiving demands, as well as by both the actor and partner effects of family demands. The APIM method gives new insight into how parental data can be analyzed by taking both the individual and the partner contribution into account when studying family phenomena. Knowing how outcomes may be influenced not only by individuals (via an actor effect) but also by their partners (through a partner effect) enriches our understanding of how families function.

  11. Ideological Challenges to Changing Strategic Orientation in Commodity Agriculture

    DEFF Research Database (Denmark)

    Press, Melea; Arnould, Eric

    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 orientations may be thought of as ideologies; and second, that such ideologies are likely to contend with each other. Taking such a perspective may be helpful in thinking about why transitioning to more sustainable strategic orientations is challenging even in the presence of financial incentives to make such 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.

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

    DEFF Research Database (Denmark)

    Rosenlund, Signe; Broeng, Leif

    2014-01-01

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

    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.

    2011-04-01

    Full Text Available In the context of Service-Oriented Architecture (SOA, complex systems can be realized through the visualization of business driven processes. The automation of Service Supported Systems (SSS is the future integral part of core SOA which provides preprocessed information and solution suggestions for the Cloud Computing Users (CCU. CCU requires compact and fast decision supporting displays and user interface in order to handle the increasing work load. This requires intelligent, intuitive and robust preprocessing system as a backbone for automation lifecycle management. Complex business management processes often entail complex environmental decision-making procedures. This process can be greatly enhanced if it is based on an exploratory-envisioning system such as Information Exploration and Visualization Environment. Current scientific research has taken advantage of e-science to enhance distributed simulation, analysis and visualization. Many of these infrastructures use one or more collaborative software paradigms like Grid Computing, High Level Architecture (HLA and Service Oriented Architecture (SOA, which together provide an optimal environment for heterogeneous and distant, real-time collaboration. While significant progress has been made using these collaborative platforms, often there is no particular software suite that fulfils all requirements for an entire organization or case study. End-user must cope manually with a collection of tools and its exporting/importing capabilities to obtain the output needed for a particular purpose. We presents how service oriented architecture can be utilized in automation services support system using RCD framework as underlying composition platform. The introduced framework combines rapid analysis development and intelligent process state visualization for CCU and discusses the challenges met in building reliable cloud computing services for web services. Unified Modeling Language (UML is used as a specification technique for the system analysis and design process which is the only way to visualize one’s design and check it against requirements before developers start to code.

    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.

    Full Text Available In the new age one of the most challenging aspects of the information age is discovering the desired services with most accuracy and speed. In this paper a new semantic model is presented for the service discovering process in network centric warfare (NCW. The model is based on predefined ontology which is determined for the most important aspects of NCW in the application level. Services is based on a service oriented infrastructure and implemented as a grid which is developed as independent services. In the model, service discovery mechanism allows each of service agents to interact with its agent neighbors semantically and form a service chain for a specific task dynamically. The introduced model considered the semantic SOA which can overcome the undesirable time-delays and overhead corresponding to complexity of service discovery at heterogeneous environment such as NCW.

  6. Orienting ESL/EFL Students towards Critical Thinking through Pictorial Inferences and Elucidation: A Fruitful Pedagogic Approach

    2015-01-01

    Full Text Available The notions of Critical Thinking (CT and Lifelong Learning (LL are mutually inseparable as both are required in every domain of one’s educational and professional life in order to survive and flourish in today’s world of increased literacy and competition. CT is an important functional skill, needed for students to analyze concepts and ideas to get a clear understanding of them. Review of a host of definitions of CT, included in this paper, suggests that it basically involves a plethora of thinking abilities for the purposes of evaluating one’s own thinking process that results in a meaningful learning experience. However, unlike ordinary thinking, which is an inborn human ability, CT needs to be inculcated through implicit and/or explicit instruction. Many researchers (e.g. Benesch, 1993; Atkinson, 1997; Oster, 1989; Brookfield, 1987; Shor & Freire, 1987; Fox, 1994; etc. explain CT as a means to transform learning and society and they believe that social practice is one of the indispensable components of CT. In view of this, we need to orient our ESL / EFL students towards CT, along with the teaching of language skills, through interactive instructional practices. Considering the role(s CT can play in developing information-based societies and the pedagogical gains that can be made through the use of visuals in teaching language skills and CT, this paper aims to discuss and demonstrate how certain schematic pictorial presentations can be exploited as stimuli to orient ESL / EFL learners towards CT. The significance of this paper also lies in encouraging researches which explicitly link CT with pictorial presentations of cartoons and caricatures.

  9. Translating Response During Therapy into Ultimate Treatment Outcome: A Personalized 4-Dimensional MRI Tumor Volumetric Regression Approach in Cervical Cancer

    International Nuclear Information System (INIS)

    Purpose: To assess individual volumetric tumor regression pattern in cervical cancer during therapy using serial four-dimensional MRI and to define the regression parameters' prognostic value validated with local control and survival correlation. Methods and Materials: One hundred and fifteen patients with Stage IB2-IVA cervical cancer treated with radiation therapy (RT) underwent serial MRI before (MRI 1) and during RT, at 2-2.5 weeks (MRI 2, at 20-25 Gy), and at 4-5 weeks (MRI 3, at 40-50 Gy). Eighty patients had a fourth MRI 1-2 months post-RT. Mean follow-up was 5.3 years. Tumor volume was measured by MRI-based three-dimensional volumetry, and plotted as dose(time)/volume regression curves. Volume regression parameters were correlated with local control, disease-specific, and overall survival. Results: Residual tumor volume, slope, and area under the regression curve correlated significantly with local control and survival. Residual volumes ?20% at 40-50 Gy were independently associated with inferior 5-year local control (53% vs. 97%, p <0.001) and disease-specific survival rates (50% vs. 72%, p = 0.009) than smaller volumes. Patients with post-RT residual volumes ?10% had 0% local control and 17% disease-specific survival, compared with 91% and 72% for <10% volume (p <0.001). Conclusion: Using more accurate four-dimensional volumetric regression analysis, tumor response can now be directly translated into individual patients' outcome for clinical aidual patients' outcome for clinical application. Our results define two temporal thresholds critically influencing local control and survival. In patients with ?20% residual volume at 40-50 Gy and ?10% post-RT, the risk for local failure and death are so high that aggressive intervention may be warranted.

    Background Standing balance is imperative for mobility and avoiding falls. Use of an excessive number of standing balance measures has limited the synthesis of balance intervention data and hampered consistent clinical practice. Objective To develop recommendations for a core outcome set (COS) of standing balance measures for research and practice among adults. Methodology A combination of scoping reviews, literature appraisal, anonymous voting and face-to-face meetings with fourteen invited experts from a range of disciplines with international recognition in balance measurement and falls prevention. Consensus was sought over three rounds using pre-established criteria. Data sources The scoping review identified 56 existing standing balance measures validated in adult populations with evidence of use in the past five years, and these were considered for inclusion in the COS. Results Fifteen measures were excluded after the first round of scoring and a further 36 after round two. Five measures were considered in round three. Two measures reached consensus for recommendation, and the expert panel recommended that at a minimum, either the Berg Balance Scale or Mini Balance Evaluation Systems Test be used when measuring standing balance in adult populations. Limitations Inclusion of two measures in the COS may increase the feasibility of potential uptake, but poses challenges for data synthesis. Adoption of the standing balance COS does not constitute a comprehensive balance assessment for any population, and users should include additional validated measures as appropriate. Conclusions The absence of a gold standard for measuring standing balance has contributed to the proliferation of outcome measures. These recommendations represent an important first step towards greater standardization in the assessment and measurement of this critical skill and will inform clinical research and practice internationally.

    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.

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

    International Nuclear Information System (INIS)

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

    Many methods of surgical repair of pure medial orbital fractures have been reported. In this study, we discuss the outcome from the surgical corrections of hydroxyapatite (Biocoral) or porous polyethylene (Medpor) through subciliary approach, and the transnasal endoscopic corrections. Between March 1993 and July 2003, 63 patients were treated with porous polyethylene and 48 patients were treated with hydroxyapatite. Between August 2003 and December 2005, 50 patients were treated with transnasal endoscopic approach. Patients had at least 6 months' follow-up, and the records for diplopia, enophthalmos, and other postoperative complications were reviewed retrospectively. As a result, 1 patient from the group using porous polyethylene, 2 patients from the group using hydroxyapatite, and 1 patient from the endoscopic correction group had enophthalmos. Besides enophthalmos, no other complications were observed. There was no significant statistical correlation among 3 groups. In conclusion, a transnasal endoscopic correction may be considered a useful method for surgical repair of pure medial orbital fractures, with no external facial scar and excellent visualization and accuracy comparable to that of the subciliary approach.

  5. 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.

Vale ressaltar o número expressivo de acadêmicos (42%) que não realizaram a Classificação dos Resultados de Enfermagem. CONCLUSÃO: Baseando-se nos resultados desta pesquisa torna-se necessária uma reflexão sobre a avaliação do paciente com dor, assim como sobre as condutas de enfermagem necessárias para suprir ou amenizar tal problemática. Acrescenta-se a esta pesquisa a falta de preparo dos futuros profissionais e a necessidade de mudança de postura perante o domínio técnico-científico exigido pela profissão. Abstract in english BACKGROUND AND OBJECTIVES: Nurses, as members of the health team, have to play their role to control pain, and are accountable for diagnostic evaluation, intervention and monitoring of treatment outcomes. This study aimed at identifying nursing students' approaches on interventions as from pain nur [...] sing diagnosis, according to taxonomy II of the North American Nursing Diagnosis Association and the association of nursing outcomes regarding interventions. METHODS: This is a transversal and quantitative study using as tool a clinical case. Studied sample was made up of 60 nursing students in the last graduation period. The research was carried out in two Public Universities, both in the state of Pernambuco. RESULTS: From the evaluated sample, most students (69%) have not presented interventions for the clinical case. From 31% presenting interventions, only 58% have presented expected outcomes, according to Nursing Outcomes Classification based on planned interventions. It is worth stressing the large number of students (42%) who have not performed the Nursing Outcomes Classification. CONCLUSION: Based on the results of this research, it is necessary a reflection about painful patients' evaluation, as well as about nursing approaches needed to solve or minimize such problem. One should add to this research the lack of qualification of future professionals and the need to change posture with regard to technical-scientific knowledge required by the profession.

  8. Finding and Classifying Critical Points of 2D Vector Fields: A Cell-Oriented Approach Using Group Theory

    CERN Document Server

    Effenberger, Felix

    2010-01-01

    We present a novel approach to finding critical points in cell-wise barycentrically or bilinearly interpolated vector fields on surfaces. The Poincar\\e index of the critical points is determined by investigating the qualitative behavior of 0-level sets of the interpolants of the vector field components in parameter space using precomputed combinatorial results, thus avoiding the computation of the Jacobian of the vector field at the critical points in order to determine its index. The locations of the critical points within a cell are determined analytically to achieve accurate results. This approach leads to a correct treatment of cases with two first-order critical points or one second-order critical point of bilinearly interpolated vector fields within one cell, which would be missed by examining the linearized field only. We show that for the considered interpolation schemes determining the index of a critical point can be seen as a coloring problem of cell edges. A complete classification of all possible...

    Precise chromosome segregation during cell division results from the attachment of chromosomes to microtubules emanating from both poles of the spindle apparatus. The molecular machinery involved in establishing and maintaining properly oriented microtubule attachments remains murky. Some clarity is now emerging with the identification of Bod1 (Biorientation Defective 1), a protein that promotes chromosome biorientation by unleashing chromosomes from improperly oriented microtubule attachments.

    With the rising global prevalence in diabetes, healthcare systems are facing a growing challenge to provide efficient and effective diabetes care management in the face of spiralling treatment costs. Diabetes is a major cause of premature mortality and associated with devastating complications especially if managed poorly. Although diabetes care is improving in England and Wales, recent audit data suggests care remains imperfect with wide geographical variations in quality. Diabetes care is expensive with a sizeable amount of available expenditure used for treating the complications of diabetes. A target driven, long-term, multifactorial intervention in patients with type 2 diabetes has been shown to reduce mortality and morbidity. The alphabet strategy is a novel approach to effective diabetes care provision, aiming to address patient education and empowerment, provide consistent comprehensive care delivered in a timely fashion, and allowing multidisciplinary team work.

    By combining experimental and theoretical approaches, the electronic structure, molecular orientation, charge transfer dynamics and solar cell performance in donor/acceptor copolymer poly[2,7-(9,9-bis(2-ethylhexyl)-dibenzosilole)-alt-4,7-bis(thiophen-2-yl) benzo-2,1,3-thiadiazole] (PSiF-DBT) films and blended with 6,6.-phenyl-C 61-butyric acid methyl ester (PSiF-DBT:PCBM) were investigated. Good agreement between experimental and theoretical PSiF-DBT UV-Vis absorption spectrum is observed and the main molecular orbitals contributing to the spectrum were determined using DFT single point calculations. Non-coplanar configuration was determined by geometric optimization calculation in isolated PSiF-DBT pentamer and corroborated by angular variation of the sulphur 1s near-edge X-ray absorption fine structure (NEXAFS) spectra. Edge-on and plane-on molecular orientations were obtained for thiophene and benzothiadiazole units, respectively. A power conversion efficiency up to 1.58%, open circuit voltage of 0.51 V, short circuit current of 8.71 mA/cm2 and a fill factor of 35% was obtained using blended PSiF-DBT:PCBM as active layer in a bulk heterojunction solar cell. Ultrafast electron dynamics in the low-femtosecond regime was evaluated by resonant Auger spectroscopy using the core-hole clock methodology around sulphur 1s absorption edge. Electron delocalization times for PSiF-DBT and PSiF-DBT:PCBM polymeric films were derived for selected excitation energies corresponding to the main transitions in the sulphur 1s NEXAFS spectra. The mixture of PSiF-DBT with PCBM improves the charge transfer process involving the ?* molecular orbital of the thiophene units

    Full Text Available Extant literatures suggest three different approaches to decision making for operating a firm internationally: ethnocentric, polycentric, and geocentric. This study investigated differences in firm characteristics, export marketing strategies and export performance outcomes across these three orientations on a sample of North American (Canadian and U.S. firms. The findings revealed major differences in examined variables across these decision-making orientations. While global mindset seemed to influence export strategy and performance, it did not affect many aspects of firm characteristics. Implications for export managers and public policy are drawn from the results.

    2015-01-01

    PRIMARY OBJECTIVE: The aim of this study was to examine the effect of a systematic reality orientation program (RO) introduced in a neurointensive care unit on duration of posttraumatic amnesia (PTA) and outcomes of patients with traumatic brain injury (TBI). RESEARCH DESIGN: This study used a quasiexperimental, prospective design. METHODS AND PROCEDURES: Twenty-four patients (intervention) with a significant TBI classified as moderate-to-severe injuries as measured by scores of less than 12 on the Glasgow Coma Scale underwent an RO program compared with a similar group of 38 patients (control) who received a conventional rehabilitation program. The Rancho Los Amigos Score was used to assess the cognitive level 24 hours after the end of sedation, and the Galveston Orientation and Amnesia Test was used daily to assess orientation and duration of PTA. The Glasgow Outcome Scale Extended was then used as an indicator of clinical outcome after 12 months. MAIN OUTCOMES AND RESULTS: The preliminary results indicated that patients who received the RO had a higher mean of the Glasgow Outcome Scale Extended (SD = 1.53) than those receiving the usual care (SD = 1.35) despite that the groups differed significantly (p = .01) in PTA duration. CONCLUSION: Patients with TBI may benefit from early assessment and systematic RO nursing intervention. The RO may facilitate patients with PTA to regain orientation and interact with their surroundings in the neurointensive care unit to optimize the recovery. However, further studies with focus on timing, intensity, and duration are needed to evaluate the influence of an early RO approach on PTA and outcomes in patients experiencing TBI.

    International Nuclear Information System (INIS)

    The preferred growth orientations of YBa2Cu3O7-? (YBCO) thin films on (100) MgO substrates produced by pulsed laser deposition are reported. In particular, (103) perpendicular oriented films were successfully demonstrated. The crystallographic properties of the oriented films were examined by transmission electron microscopy and X-ray diffraction pole figure analyses, indicating a 45o tilt of the superconducting CuO2 planes relative to the substrate surface. This work provides a unique pathway to realizing the growth of (103) oriented YBCO films on highly valued electronic and microwave (100) MgO substrates.

  19. Orientation precision of TEM-based orientation mapping techniques

    International Nuclear Information System (INIS)

    Automatic orientation mapping is an important addition to standard capabilities of conventional transmission electron microscopy (TEM) as it facilitates investigation of crystalline materials. A number of different such mapping systems have been implemented. One of their crucial characteristics is the orientation resolution. The precision in determination of orientations and misorientations reached in practice by TEM-based automatic mapping systems is the main subject of the paper. The analysis is focused on two methods: first, using spot diffraction patterns and ‘template matching’, and second, using Kikuchi patterns and detection of reflections. In simple terms, for typical mapping conditions, their precisions in orientation determination with the confidence of 95% are, respectively, 1.1° and 0.3°. The results are illustrated by example maps of cellular structure in deformed Al, the case for which high orientation sensitivity matters. For more direct comparison, a novel approach to mapping is used: the same patterns are solved by each of the two methods. Proceeding from a classification of the mapping systems, the obtained results may serve as indicators of precisions of other TEM-based orientation mapping methods. The findings are of significance for selection of methods adequate to investigated materials. - Highlights: • Classification of the existing TEM-based orientation mapping systems. • Reliable data on orientation precision in TEM-based orientation maps. • Orientation precisions in spot and Kikuchi based maps estimated to be 1.1° and 0.3°. • New method of mapping by using spot and Kikuchi components of the same patterns

    Efficient and accurate adverse outcome pathway (AOP) based high-throughput screening (HTS) methods use a systems biology based approach to computationally model in vitro cellular and molecular data for rapid chemical prioritization; however, not all HTS assays are grounded by relevant in vivo exposure data. The challenge is to develop HTS assays with unambiguous quantitative links between in vitro responses and corresponding in vivo effects, which is complicated by metabolically insufficient systems, in vitro to in vivo extrapolation (IVIVE), cross-species comparisons, and other inherent issues correlating IVIVE findings. This article introduces the concept of ultrasensitive gas phase probe molecules (PrMs) to help bridge the current HTS assay IVIVE gap. The PrM concept assesses metabolic pathways that have already been well-defined from intact human or mammalian models. Specifically, the idea is to introduce a gas phase probe molecule into a system, observe normal steady state, add chemicals of interest, and quantitatively measure (from headspace gas) effects on PrM metabolism that can be directly linked back to a well-defined and corresponding in vivo effect. As an example, we developed the pharmacokinetic (PK) parameters and differential equations to estimate methyl tertiary butyl ether (MTBE) metabolism to tertiary butyl alcohol (TBA) via cytochrome (CYP) 2A6 in the liver from human empirical data. Because MTBE metabolic pathways are well characterized from in vivo data, we can use it as a PrM to explore direct and indirect chemical effects on CYP pathways. The PrM concept could be easily applied to in vitro and alternative models of disease and phenotype, and even test for volatile chemicals while avoiding liquid handling robotics. Furthermore, a PrM can be designed for any chemical with known empirical human exposure data and used to assess chemicals for which no information exists. Herein, we propose an elegant gas phase probe molecule-based approach to in vitro toxicity testing. PMID:25692543

  1. Effects of multiple electronic shells on strong-field multiphoton ionization and high-order harmonic generation of diatomic molecules with arbitrary orientation: An all-electron time-dependent density-functional approach

    International Nuclear Information System (INIS)

    We present a time-dependent density-functional theory approach with proper long-range potential for an ab initio study of the effect of correlated multielectron responses on the multiphoton ionization (MPI) and high-order harmonic generation (HHG) of diatomic molecules N2 and F2 in intense short laser pulse fields with arbitrary molecular orientation. We show that the contributions of inner molecular orbitals to the total MPI probability can be sufficiently large or even dominant over the highest-occupied molecular orbital, depending on detailed electronic structure and symmetry, laser field intensity, and orientation angle. The multielectron effects in HHG are also very important. They are responsible for enhanced HHG at some orientations of the molecular axis. Even strongly bound electrons may have a significant influence on the HHG process.

    2008-04-01

    The authors assessed the impact that social value orientations--prosocial (i.e., concerned about outcomes for both oneself and others) versus proself (i.e., concerned about one's own outcome only)--had on fairness judgments in a non-negotiation setting. The results indicated that prosocials generally formed fairness judgments in a manner suggested by equity theory: Given the same input as a comparison other, they saw an equal outcome as fairer than a favorable or unfavorable outcome. The fairness determinations of proselfs, however, tended to follow the tenets of self-interest theory: Given the same input as a comparison other, they saw a favorable outcome as fairer than an unfavorable outcome. Contrary to self-interest theory, proselfs did not find a favorable outcome fairer than an equal outcome. These findings indicate that social value orientations differentially affect the evaluation of outcome information in the formation of fairness judgments. PMID:18512420

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

  6. Selection of target sequences as well as sequence identity determine the outcome of RNAi approach for resistance against cotton leaf curl geminivirus complex

    2011-03-01

    Full Text Available Abstract Cotton leaf curl disease is caused by a geminivirus complex that involves multiple distinct begomoviruses and a disease-specific DNA satellite, cotton leaf curl Multan betasatellite (CLCuMB, which is essential to induce disease symptoms. Here we have investigated the use of RNA interference (RNAi for obtaining resistance against one of the viruses, Cotton leaf curl Multan virus (CLCuMV, associated with the disease. Three hairpin RNAi constructs were produced containing either complementary-sense genes essential for replication/pathogenicity or non-coding regulatory sequences of CLCuMV. In transient assays all three RNAi constructs significantly reduced the replication of the virus in inoculated tissues. However, only one of the constructs, that targeting the overlapping genes involved in virus replication and pathogenicity (the replication-associated protein (Rep, the transcriptional activator protein and the replication enhancer protein was able to prevent systemic movement of the virus, although the other constructs significantly reduced the levels of virus in systemic tissues. In the presence of CLCuMB, however, a small number of plants co-inoculated with even the most efficient RNAi construct developed symptoms of virus infection, suggesting that the betasatellite may compromise resistance. Further analyses, using Rep gene sequences of distinct begomoviruses expressed from a PVX vector as the target, are consistent with the idea that the success of the RNAi approach depends on sequence identity to the target virus. The results show that selection of both the target sequence, as well as the levels of identity between the construct and target sequence, determine the outcome of RNAi-based resistance against geminivirus complexes.

The 32 depression items studied were modified from several widely used instruments. DIF analyses of gender, age and education were performed using a sample of 735 individuals recruited by a survey polling firm. DIF hypotheses were generated by asking content experts to indicate whether or not they expected DIF to be present, and the direction of the DIF with respect to the studied comparison groups. Primary analyses were conducted using the graded item response model (for polytomous, ordered response category data with likelihood ratio tests of DIF, accompanied by magnitude measures. Sensitivity analyses were performed using other item response models and approaches to DIF detection. Despite some caveats, the items that are recommended for exclusion or for separate calibration were "I felt like crying" and "I had trouble enjoying things that I used to enjoy." The item, "I felt I had no energy," was also flagged as evidencing DIF, and recommended for additional review. On the one hand, false DIF detection (Type 1 error was controlled to the extent possible by ensuring model fit and purification. On the other hand, power for DIF detection might have been compromised by several factors, including sparse data and small sample sizes. Nonetheless, practical and not just statistical significance should be considered. In this case the overall magnitude and impact of DIF was small for the groups studied, although impact was relatively large for some individuals.

    In carbon ion radiotherapy there is an urgent clinical need to develop objective tools for the conversion of relative biological effectiveness (RBE)-weighted doses based on different models. In this work we introduce a clinically oriented method to compare NIRS-based and LEM-based GyE systems, minimizing differences in physical dose distributions between treatment plans. Carbon ion plans were optimized on target volumes of cubic and spherical shapes, for RBE-weighted dose prescription levels ranging from 3.6 to 4.4 GyE. Plans were calculated for target sizes from 4 to 12 cm defining three beam geometries: single beam, opposed beam and orthogonal beam configurations. The two treatment planning systems currently employed in clinical practice were used, providing the NIRS-based and LEM-based GyE calculations. Physical dose distributions of NIRS-based and LEM-based treatment plans were compared. LEM-based prescription doses that minimize differences in physical dose distributions between the two systems were found. These doses were compared with the mean RBE-weighted dose obtained with a Monte Carlo code (FLUKA) interfaced with LEM I. In the investigated dose range, LEM-based RBE-weighted prescription doses, that minimize differences with NIRS plans, should be higher than NIRS reported prescription doses. The optimal dose depends on target size, shape and position, number of beams and dose level. The opposed beam configuration resulted in the smallest average prescription dose difference (0.45 ± 0.09 GyE). The second approach of recalculating NIRS RBE-weighted dose with a Monte Carlo code interfaced with LEM resulted in no significant difference with the results obtained from the planning study. The delivery of a voxel by voxel iso-effective plan, if different RBE models are employed, is not feasible; it is however possible to minimize differences in a treatment plan with the simple approach presented here. Dose prescription ultimately represents a clinical task under the responsibility of the radiation oncologist, the presented analysis intends to be a quantitative and objective way to assist the clinical decision.

    Although integrated approaches are recommended and effective for treating patients with co-occurring substance use and psychotic disorders (SUD-PSY), many patients receive standard, nonintegrated substance use disorder (SUD) treatment. Research has yet to investigate how patients with co-occurring substance use and psychotic disorders respond to standard SUD treatment, an issue we address here. In a naturalistic follow-up of 236 male SUD-PSY patients receiving 12-step facilitation or cognitive-behavioral-oriented SUD treatment, we found that patients (1) demonstrated significant improvements in proximal outcomes (e.g., approach coping) from treatment intake to discharge, and in distal outcomes (e.g., psychiatric symptoms, substance use frequency) from treatment intake to 1- and 5-year follow-ups, and (2) tended to have similar outcomes whether they received 12-step facilitation or cognitive-behavioral SUD treatment. Patients who (3) were more involved in treatment, as reflected by more positive perceptions of and more satisfaction, tended to experience better proximal outcomes and engage in more continuing care, and those who (4) experienced better proximal outcomes tended to have better psychiatric and substance use outcomes in the years following treatment. Our results suggest that SUD-PSY patients can benefit from standard SUD treatments, even though it may not directly address their psychiatric disorders. PMID:23453585

  20. Customizable Time-Oriented Visualizations

    Kuhail, Mohammad Amin; Pantazos, Kostas

    2012-01-01

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

  4. Outcome predictors for 143 patients with superior sulcus tumors treated by multidisciplinary approach at the University of Texas M. D. Anderson Cancer Center

    International Nuclear Information System (INIS)

    Purpose: Superior sulcus tumors (SST) of the lung are uncommon and constitute approximately 3% of non-small cell lung cancer (NSCLC). These tumors cause specific symptoms and signs, and are associated with patterns of failure that differ from those seen for NSCLC tumors in other nonapical locations. Prognostic factors and most effective treatments are controversial. We conducted a retrospective study at The University of Texas M. D. Anderson Cancer Center to identify outcome predictors for patients with SST treated by a multidisciplinary approach. Methods and Materials: This retrospective review of 143 patients without distant metastasis at presentation is a continuation of a previous M. D. Anderson study now updated to 1994. In this study, we examine the 5-year survival rate by pretreatment tumor and patient characteristics and by the treatments received. Strict criteria were used to define SST. Actuarial life-table analyses and Cox proportional hazard models were used to compare survival rates. Results: Overall predictors of 5-year survival were weight loss (p < 0.01), supraclavicular fossa (p = 0.03), or vertebral body (p = 0.05) involvement, stage of the disease (p < 0.01), and surgical treatment (p < 0.01). Five-year survival for patients with Stage IIB disease was 47% compared to 14% for Stage IIIA, and 16% for Stage IIIB. For patients with Stage IIB disease, surgical treatment (p < 0.01) and weight loss (p = 0.01) were significant independent predictors of 5-yesignificant independent predictors of 5-year survival. Among patients with Stage IIIA disease, the only predictor of survival was Karnofsky performance score (KPS) (p = 0.02). For patients with Stage IIIB disease, the only independent predictor of survival was a right superior sulcus location, which was associated with a worse 5-year survival rate than that for patients with tumors in the left superior sulcus (p = 0.02). More patients with adenocarcinoma than with squamous cell tumors experienced cerebral metastases within 5 years (p < 0.01). Patients without gross residual disease after surgical resection who received postoperative radiation therapy with total doses of 55 to 64 Gy had a 5-year survival rate of 82% as compared with the 5-year survival rate of 56% in patients who received 50 to 54 Gy. Twenty-three patients survived for longer than 3 years. Of these, 4 patients (17%) received radiation therapy alone or in combination with chemotherapy without surgical resection. The other 19 patients (83%) had resection combined with radiation therapy and/or chemotherapy. Conclusions: The findings from this study confirm the importance of the new staging system, separating T3 N0 M0 (Stage IIB) from Stage IIIA, since there was a significant difference in the 5-year survival (p < 0.01). Interestingly, there was no significant 5-year survival difference between Stage IIIA (N2) and Stage IIIB (T4 or N3). This study also suggests that surgery is an important component of the multidisciplinary approach to patients with SST if their nodes were negative. Disease that is minimally invading surrounding normal structures can be resected followed by radiation therapy in doses of 55 to 64 Gy. Further investigation of treatment strategies combining high-dose radiation therapy (?66 Gy) with chemotherapy is indicated for patients with unresectable and/or node-positive (N2) SST

  5. From volume to value? Can a value-based approach help deliver the ambitious aims of the NHS cardiovascular disease outcomes strategy?

    Science.gov (United States)

    Dunbar-Rees, Rupert; Panch, Trishan; Dancy, Mark

    2014-06-01

    The last year has seen the publication of two papers which will radically shape the future organisation of healthcare in general, and cardiovascular disease in particular: Cardiovascular Outcomes Strategy (Department of Health) and The Strategy That Will Fix Healthcare (Harvard Business Review). Both publications set out a health delivery mechanism based around improvement of outcomes for groups of patients with similar needs. Instead of organising care around disease categories, it is proposed that the cardiovascular diseases are treated as a single family of diseases. We are reaching the limits of what an activity-based system organised around existing provider structures can sustainably deliver. Unless we find delivery systems which reduce costs while at the same time improving outcomes that are meaningful to patients, then we will be faced with a future of healthcare rationing. The increasing burden of chronic disease and ongoing quality concerns in delivery systems has created a 'burning platform', which must be addressed if we are to maintain a system which offers high-quality care free at the point of delivery. This paper explores what an outcomes and value-based system could look like when applied to cardiovascular disease. It explores what it means for providers and patients if we start to think about outcomes by patients with similar needs, rather than by intervention, or by clinical specialty. As a specific example, the paper explores the features of an Integrated Circulation Service, what the challenges and implications might be, and whether there is any evidence that this would deliver improved outcomes, at a lower cost to the system.

  7. Does Early Childhood Teacher Education Affect Students' Cognitive Orientations?

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Early childhood teachers may differ regarding the knowledge base they use when making professional decisions. In this study two orientations are distinguished: the orientation towards scientific knowledge vs. the orientation towards intuition and subjective experience. As different tracks in early childhood teacher education qualify for professional practice, and as education of early childhood teachers matters with regard to developmental outcomes of children, knowledge orientations of prospective early childhood teachers attending universities and attending vocational schools are investigated and compared. Knowledge orientations were assessed by means of a questionnaire. After propensity score matching of 402 beginners and 402 graduates, multilevel analyses indicate that scientific orientation at the end of teacher education was higher and subjective orientation was lower than at the beginning. Furthermore, scientific knowledge orientation of BA-students was higher, subjective orientation was lower than of students at professional schools. Implications of these results regarding education of early childhood teachers are discussed.

  16. Orienting hypnosis.

    Science.gov (United States)

    Hope, Anna E; Sugarman, Laurence I

    2015-01-01

    This article presents a new frame for understanding hypnosis and its clinical applications. Despite great potential to transform health and care, hypnosis research and clinical integration is impaired in part by centuries of misrepresentation and ignorance about its demonstrated efficacy. The authors contend that advances in the field are primarily encumbered by the lack of distinct boundaries and definitions. Here, hypnosis, trance, and mind are all redefined and grounded in biological, neurological, and psychological phenomena. Solutions are proposed for boundary and language problems associated with hypnosis. The biological role of novelty stimulating an orienting response that, in turn, potentiates systemic plasticity forms the basis for trance. Hypnosis is merely the skill set that perpetuates and influences trance. This formulation meshes with many aspects of Milton Erickson's legacy and Ernest Rossi's recent theory of mind and health. Implications of this hypothesis for clinical skills, professional training, and research are discussed. PMID:25928677

    Full Text Available By the fast growing generation the network based on the tor provides accessibility of the services based on the internet oriented applications which are based on the private scenario by the connection oriented routers based on the server where the client’s oriented address based on the IP is hidden. Where the performance is somewhat is effective due to the limitation based on the network based connectivity. These problems are faced due to some of the ill conditioning based parameters respectively such as appearance of the network based scenario is quite effective respectively. Administration related websites are completely dependent on the address of the IP oriented phenomena respectively in which the disabling of the access takes due to the ill conditioning of the user baser scenario in terms of the misbehavior oriented phenomena respectively. Now moving towards the practical oriented phenomena this is not the perfect solution based on the blocking of the address based on the IP scenario. Finally resulting in such an oriented phenomena where blocking is done by the help of the admin oriented issue at the nodal side respectively. These particular phenomena plays a vital role and somewhat beneficiary aspect in terms of the controlling the misbehavior of the user. Therefore in order to overcome the above problem a framework is designed by the name of nimble in such a fashion which is used to overcome the above phenomena by the following considerations where the entire action takes place by the help of the server’s oriented approach. Therefore this particular phenomena plays a vital role in order to improve the performance of the system respectively.

    To be meaningful to guide the rational design of novel high-performance conjugated semiconductors, we prepared three benzo[1,2-b:4,5-b']dithiophene (BDT)-based polymers by systematically moving the branching point of the alkyl chain. The effect of side-chain engineering was thoroughly investigated by a range of techniques. We demonstrate that a subtle change in the branching position in the BDT core can have a critical impact on polymer packing and preferential backbone orientation in thin films; copolymers made from BDT and thieno[3,4-c]pyrrole-4,6-dione units (TPD) adopt more of a face-on orientation as the branching point is shifted closer to the backbone, which can be correlated with a dramatic difference in solar-cells performance. The high short-circuit current density (11.6 mA?cm(-2) ) for the copolymer with one carbon atom between the alkoxylated oxygen atom and the branching point results from its predominantly face-on orientation and smoother surface in thin films, which results in power conversion efficiencies as high as 4.56?%.

    2015-03-01

    Considering specific physiology changes during gestation and thinking of pregnancy as a "critical window", classification of pregnant women at early pregnancy can be considered as crucial. The paper demonstrates the use of a method based on an approach from intelligent data mining, cluster analysis. Cluster analysis method is a statistical method which makes possible to group individuals based on sets of identifying variables. The method was chosen in order to determine possibility for classification of pregnant women at early pregnancy to analyze unknown correlations between different variables so that the certain outcomes could be predicted. 222 pregnant women from two general obstetric offices' were recruited. The main orient was set on characteristics of these pregnant women: their age, pre-pregnancy body mass index (BMI) and haemoglobin value. Cluster analysis gained a 94.1% classification accuracy rate with three branch- es or groups of pregnant women showing statistically significant correlations with pregnancy outcomes. The results are showing that pregnant women both of older age and higher pre-pregnancy BMI have a significantly higher incidence of delivering baby of higher birth weight but they gain significantly less weight during pregnancy. Their babies are also longer, and these women have significantly higher probability for complications during pregnancy (gestosis) and higher probability of induced or caesarean delivery. We can conclude that the cluster analysis method can appropriately classify pregnant women at early pregnancy to predict certain outcomes. PMID:26040101

    Osteoarthritis (OA) is a disease that primarily results in the degeneration and destruction of the articular cartilage. However, synovitis that occurs secondarily by this primary phenomenon is crucial for both the structural and symptomatic progression of the disease. The Japanese Knee Osteoarthritis Measure (JKOM) was created as an outcome measure for Japanese patients with knee OA. This study was conducted to determine whether synovitis in knee OA correlates with the current disability of patients with knee OA who required total knee arthroplasty (TKA). Thirty-four Japanese patients with end-stage knee OA who required TKA were included in this study. The visual analog scale (VAS, 0-100) for pain and the JKOM score, as well as the Western Ontario and McMaster Universities Arthritis Index (WOMAC), were examined before the operation. Synovial samples were taken at the time of the operation. A histological analysis and gadolinium-enhanced magnetic resonance imaging (Gd-MRI) were conducted to evaluate synovitis. Correlations between the synovitis score evaluated by histological analysis and Gd-MRI with either the pain VAS score or the JKOM score were examined using Spearman's rank correlation coefficient. Neither the synovitis scores evaluated by the histological analysis nor those by a Gd-MRI correlated with the pain VAS score (n = 34, r = 0.25, p = 0.18 and r = 0.08, p = 0.75, respectively) and WOMAC (n = 14, r = 0.35, p = 0.22 and r = 0.45, p = 0.16, respectively) of the patients. However, they significantly correlated with the JKOM score of the patients (n = 34, r = 0.55, p = 0.001 and r = 0.71, p = 0.001, respectively). The severity of synovitis in OA was closely correlated with the current functional impairment and disability of the patients receiving TKA with end-stage knee OA. PMID:20567866

    This article seeks to understand why developing country suppliers internalize or outsource labour-intensive aspects of production as well as how these internalization/externalization processes affect working conditions in export-orientated industries in the global South. In order to achieve this aim, the article develops a new analytical framework based upon the global value chain approach. Applying this framework to the football manufacturing industry of Jalandhar, India, the article concludes that value chain restructuring produces both new forms of work organization and highly gendered outcomes for labour in this industry.

    To date, there is no experimental characterization of thermal conductivity of semiconductor polymeric individual nanowires embedded in a matrix. This work reports on scanning thermal microscopy measurements in a 3? configuration to determine how the thermal conductivity of individual nanowires made of a model conjugated polymer (P3HT) is modified when decreasing their diameters. We observe a reduction of thermal conductivity, from ?NW = 2.29 ± 0.15 W K(-1) m(-1) to ?NW = 0.5 ± 0.24 W K(-1) m(-1), when the diameter of nanowires is reduced from 350 nm to 120 nm, which correlates with the polymer crystal orientation measured by WAXS. Through this work, the foundations for future polymer thermal transport engineering are presented. PMID:24933655

    Full Text Available Process-oriented diagnostics require a theoretical framework which allows to describe and interpret individual competence changes. For MARKO-test, a corresponding dimension/scale of mathematical achievement in preschool age was developed on the basis of theoretical assumptions and empirical data. Five essential concepts are: numbers as counting sequence, ordinal number line, cardinal understanding, part – part – whole and concept of congruent intervals. There is empirical evidence for the validity of the model, using a unidimensional Rasch model. Therefore, a concept of testing is available which on the one hand allows to compare individual data with a social norm and on the other hand is usable to make valid statements about individual changes and the current development status of a child.

    2015-06-01

    Inspired by the agitation effect of propellers, heterogeneous propeller- shaped CaO/ZnO architectures were assembled in aqueous solution. Preferred nucleation and growth of CaO and ZnO nuclei resulted in their hexagonal nanosheets, and they were end to end combined into propeller-shaped architectures by oriented rotation and attachment reactions. When propeller-shaped CaO/ZnO product was used as solid base catalyst to synthesize biodiesel, a high biodiesel yield of 97.5% was achieved. The predominant exposure of active O2- on CaO(0 0 2) and ZnO(0 0 0 2) planes in propeller-shaped CaO/ZnO, led to good catalytic activity and high yield of biodiesel.

    Hauptbeschreibung Aspect-oriented-programming is a relatively new technique that has evolved on top of the already well-established approach of object-oriented programming. When it is used correctly, it promises to remove many redundant parts of a code that appear repeatedly in an application, essentially untangling the original code. Thus, it can lead to a cleaner, more separated software design, to greater modularity and maintainability. Time-savings in software engineering can also be huge cost-savings, and anything that increases software quality is a welcome sight in an industr

    The toxicological effects of many stressors are mediated through unknown, or poorly characterized, mechanisms of action. We describe the application of reverse engineering complex interaction networks from high dimensional omics data (gene, protein, metabolic, signaling) to characterize adverse outcome pathways (AOPs) for chemicals that disrupt the hypothalamus-pituitary-gonadal endocrine axis in fathead minnows. Gene expression changes in fathead minnow ovaries in response to 7 different chemicals, over different times, doses, and in vivo versus in vitro conditions were captured in a large data set of 868 arrays. We examined potential AOPs of the antiandrogen flutamide using two mutual information theory methods, ARACNE and CLR to infer gene regulatory networks and potential adverse outcome pathways. Representative networks from these studies were used to predict a network path from stressor to adverse outcome as a candidate AOP. The relationship of individual chemicals to an adverse outcome can be determined by following perturbations through the network in response to chemical treatment leading to the nodes associated with the adverse outcome. Identification of candidate pathways allows for formation of testable hypotheses about key biologic processes, biomarkers or alternative endpoints, which could be used to monitor an adverse outcome pathway. Finally, we identify the unique challenges facing the application of this approach in ecotoxicology, and attempt to provide a road map for the utilization of these tools.

    The Coulomb Stress changes due to the some moderate and large earthquakes are shaped according to the orientations of reciever faults or weakness zones along the corresponding seismogenic zones. In some cases, the determination of the fault plane parameters (e.g. length, width, strike, dip) of the receiver faults are more difficult due to the tectonical complexity of the region. Therefore, in order to understand the aftershock distrubition in such areas Coulomb stress changes can be calculated under the assumption of optimally oriented fault planes which increases the spatial correlation between stress changes and aftershock distribution. In the scope of the present sutdy, aftershock distrubiton of some contemporary earthquakes in Turkey (Simav (Mw 5.8), May 2011; Van (Mw 7.0), Oct 2011 and Gulf of Fethiye (Mw 6.1), June 2012) and their coulomb stress changes were correlated. Fault plane parameters of these earthquakes which suggest three different types of focal mechanism were calculated using moment tensor inversion technique and aftershock location data in a period of 30 days for each corresponding events were taken from Kandilli Observatory and Earthquake Research Institute (KOERI) catalog. The focal mechanisms of the selected earthquakes represent normal, strike slip and thrust faulting for the earthquakes of Simav, Gulf of Fethite and Van, respectively. Coulomb Stress Changes were calculated using the open source Matlab based (Coulomb 3.3) codes. The calculations were performed by assuming Poisson's ratio and apparent friction coefficient to be 0.25 and 0.4, respectively. The coulomb stress variations were calculated at fixed depths for each event and aftershocks were selected as ±4 km for corresponding depths. Keeping in mind that the increase of static stress more than 0.5 bar can cause the triggered events in an area, the accordance rates of Coulomb stress changes and aftershock distribution under different tectonic regimes were disscussed. The accordance rates are %84, %80 and %68 in the extensional, strike slip and thrust type faulting, respectively.

  16. Outcome-Based Planning-Hanford's Shift Towards Closure and Shrinking the Hanford Site

    International Nuclear Information System (INIS)

    Over the past two years, the U.S. Department of Energy (DOE) Richland Operations Office (RL) has formulated a focused, outcomes-based vision for accelerated cleanup of the Hanford Site. The primary elements, or outcomes, of this vision are to (1) accelerate restoration of the Columbia River Corridor, (2) transition the Central Plateau to long-term waste management, thereby shrinking the footprint of active site cleanup and operations, and (3) prepare for the future. The third outcome includes operation of the Pacific Northwest National Laboratory (PNNL), a key element of the foundation for Hanford's future; leveraging DOE's assets; and working with the community to understand their vision and reflect it as appropriate in the execution of the Hanford 2012 Vision. The purpose of these three outcomes is to provide a near term focus, aimed at achieving definitive end points over the next decade, while not precluding any long-term end-state associated with the completion of the Environmental Management (EM) mission at Hanford. The sheer expanse of the Hanford Site, the inherent hazards associated with the significant inventory of nuclear materials and wastes, the large number of aging contaminated facilities, the diverse nature and extent of environmental contamination, and the proximity to the Columbia River make the Hanford Site arguably the world's largest and most complex environmental cleanup project. Current projections are that it will cost over $80 billion and takehat it will cost over $80 billion and take over four decades to complete the cleanup at Hanford. Accelerated cleanup of the River Corridor portion of the Site will allow the remediation effort to focus on specific, near-term outcomes. Hanford's success in achieving these outcomes will reduce urgent risk, shrink the Site, remove contamination and wastes from the proximity of the river, and consolidate waste management activities on the Central Plateau. Hanford has begun implementation of this vision. Performance-based contracts are being realigned to reflect the outcome orientation, including issuing a new River Corridor closure contract. This paper summarizes the outcome-based planning approach for other sites and interested parties. A brief introduction to the Hanford Site, along with detailed descriptions of the three outcomes is provided. This paper also summarizes the analyses and resulting products that were prepared in shifting to an outcome-based approach for closing the Hanford Site

    Full Text Available The objective of the current study was to analyze the seasonal effect on differentiating tree species in an urban environment using multi-temporal hyperspectral data, Light Detection And Ranging (LiDAR data, and a tree species database collected from the field. Two Airborne Imaging Spectrometer for Applications (AISA hyperspectral images were collected, covering the Summer and Fall seasons. In order to make both datasets spatially and spectrally compatible, several preprocessing steps, including band reduction and a spatial degradation, were performed. An object-oriented classification was performed on both images using training data collected randomly from the tree species database. The seven dominant tree species (Gleditsia triacanthos, Acer saccharum, Tilia Americana, Quercus palustris, Pinus strobus and Picea glauca were used in the classification. The results from this analysis did not show any major difference in overall accuracy between the two seasons. Overall accuracy was approximately 57% for the Summer dataset and 56% for the Fall dataset. However, the Fall dataset provided more consistent results for all tree species while the Summer dataset had a few higher individual class accuracies. Further, adding LiDAR into the classification improved the results by 19% for both fall and summer. This is mainly due to the removal of shadow effect and the addition of elevation data to separate low and high vegetation.

    Adopting socioecological, intersectionality, and lifecourse theoretical frameworks may enhance our understanding of the production of syndemic adverse health outcomes among gay, bisexual and other men who have sex with men (MSM). From this perspective, we present preliminary data from three related studies that suggest ways in which social contexts may influence the health of MSM. The first study, using cross-sectional data, looked at migration of MSM to the gay resort area of South Florida, and found that amount of time lived in the area was associated with risk behaviors and HIV infection. The second study, using qualitative interviews, observed complex interactions between neighborhood-level social environments and individual-level racial and sexual identity among MSM in New York City. The third study, using egocentric network analysis with a sample of African American MSM in Baltimore, found that sexual partners were more likely to be found through face-to-face means than the Internet. They also observed that those who co-resided with a sex partner had larger networks of people to depend on for social and financial support, but had the same size sexual networks as those who did not live with a partner. Overall, these findings suggest the need for further investigation into the role of macro-level social forces on the emotional, behavioral, and physical health of urban MSM. PMID:21369730

  2. A source-orientated approach for estimating daytime concentrations of biogenic volatile organic compounds in an upper layer of a boreal forest canopy

    2013-06-01

    Biologically justified statistical models for daytime atmospheric concentrations of methanol, acetaldehyde, acetone, isoprene and monoterpene were tested using measurements at a boreal forest stand in southern Finland in 2006-2007 and in summer 2008. The canopy-scale concentrations of all compounds except monotepene were closely correlated with shoot-scale concentrations indicating a strong link to biological emission source. All the models were based on the exponential relationship between air temperature and atmospheric concentration of biogenic volatile organic compounds (BVOCs). The first model - an exponential function of air temperature (T model) - could explain 27%-64% of the variation in BVOC daytime concentrations in the test data. The second model - a Temperature-State of Development model (T-S model) having two explaining variables (air temperature and seasonal photosynthetic efficiency) - was derived from an empirical adjustment of seasonality. This model slightly increased the fraction of explained variation but it still could not explain the high concentration peaks, which accounted for most of the unexplained variation. To better analyse these peaks we tested the Trigger model including two potential environmental triggers, a PAR index (high photosynthetically active photon flux density (PAR) and high ozone concentration, that could increase the concentrations momentarily. However, the Trigger model described the peak concentrations only somewhat better than the T or T-S model. It seems that it is very difficult to explain more than 32%-67% of variation in BVOC concentrations by a straightforward source-oriented modelling without deep understanding of biological and physical processes. In order to improve the models profound studies on specific stress factors and events inducing BVOC emissions are needed. (orig.)

    Full Text Available Metrics are units of measurement. Software engineering metrics are units of measurement that are used to characterize the software engineering products and software engineering processes. Object-oriented design and development is becoming very popular in today`s software development environment. Object-Oriented Programming Structure (OOPS requires not only a different approach to design and implementation; it requires a different approach to software metrics. Since object oriented technology uses objects and not algorithms as its fundamental building blocks, the approach to software metrics for object-oriented programs must be different from the standard metrics set. Object-oriented analysis and design focuses on objects as the primary agents involved in a computation. This study addresses the following questions: (i what are the concepts in object-oriented technology that affect the software quality? (ii How the various metrics found in the literature are useful to measure the critical concepts in object-oriented technology.

  4. A Versatile, Production-Oriented Approach to High-Resolution Tree-Canopy Mapping in Urban and Suburban Landscapes Using GEOBIA and Data Fusion

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available The benefits of tree canopy in urban and suburban landscapes are increasingly well known: stormwater runoff control, air-pollution mitigation, temperature regulation, carbon storage, wildlife habitat, neighborhood cohesion, and other social indicators of quality of life. However, many urban areas lack high-resolution tree canopy maps that document baseline conditions or inform tree-planting programs, limiting effective study and management. This paper describes a GEOBIA approach to tree-canopy mapping that relies on existing public investments in LiDAR, multispectral imagery, and thematic GIS layers, thus eliminating or reducing data acquisition costs. This versatile approach accommodates datasets of varying content and quality, first using LiDAR derivatives to identify aboveground features and then a combination of LiDAR and imagery to differentiate trees from buildings and other anthropogenic structures. Initial tree canopy objects are then refined through contextual analysis, morphological smoothing, and small-gap filling. Case studies from locations in the United States and Canada show how a GEOBIA approach incorporating data fusion and enterprise processing can be used for producing high-accuracy, high-resolution maps for large geographic extents. These maps are designed specifically for practical application by planning and regulatory end users who expect not only high accuracy but also high realism and visual coherence.

    Full Text Available The limited efficiency of current air traffic systems will require a next-generation of Smart Air Traffic System (SATS that relies on current technological advances. This challenge means a transition toward a new navigation and air-traffic procedures paradigm, where pilots and air traffic controllers perform and coordinate their activities according to new roles and technological supports. The design of new Human-Computer Interactions (HCI for performing these activities is a key element of SATS. However efforts for developing such tools need to be inspired on a parallel characterization of hypothetical air traffic scenarios compatible with current ones. This paper is focused on airborne HCI into SATS where cockpit inputs came from aircraft navigation systems, surrounding traffic situation, controllers’ indications, etc. So the HCI is intended to enhance situation awareness and decision-making through pilot cockpit. This work approach considers SATS as a system distributed on a large-scale with uncertainty in a dynamic environment. Therefore, a multi-agent systems based approach is well suited for modeling such an environment. We demonstrate that current methodologies for designing multi-agent systems are a useful tool to characterize HCI. We specifically illustrate how the selected methodological approach provides enough guidelines to obtain a cockpit HCI design that complies with future SATS specifications.

    Full Text Available Nurses help to ensure patient safety, which includes preventing falls and fall related injuries. The aging Veteran population, like the general population, is at risk for falls and fall related injuries whether at home, in hospitals or in long term care facilities. Nurses are leading practice innovations to systematically assess patients’ risk for falls and implement population based prevention interventions. To determine the effectiveness of programs, data can be analyzed using a variety of statistical measures to determine program impacts. Thus, data analysis of fall rates by type of fall and severity of fall related injury can help facilities examine the effectiveness of their interventions and program outcomes. Examples of actual fall prevention programs and their approaches to measurement are showcased in this article.

  9. Beach morphologies induced by breakwaters with different orientations

    2015-06-01

    A desired outcome in the construction of a detached emerged breakwater is the formation of an accretionary salient in its lee to augment the beach, improve beach amenity and provide an additional buffer from storm waves. The extent to which this salient forms and its morphology are strongly controlled by the breakwater geometry with respect to the original shoreline, sediment availability, and local wave climate. The purpose of this paper is to identify how breakwater geometry and orientation of gaps between individual breakwaters alter the direction of waves entering the gaps and change the asymmetry of the salients. Four distinct breakwater sites along the Emilia-Romagna coastline in Northern Italy were chosen for a detailed field and desktop study comprising three-dimensional topographic and bathymetric surveys, sediment sampling, LiDAR flights and historical shoreline mapping. The orientations of the shorelines at these four sites range over 43°, resulting in different exposures to the dominant waves. The oblique orientations of the gaps between individual breakwater segments at three of the four sites effectively create a "gap window" between breakwaters favoring the exposure of short-period waves from the north and diminishing the effect of longer waves from the dominant east. Salients can be symmetrical despite an acute angle of approach of the dominant deep water waves where refraction is enhanced by offshore topography and breakwaters are parallel to the shore. Waves approaching normal to the gap window undergo less diffraction due to their shorter length relative to the gap window width and undergo less attenuation by breaking and bottom friction if they are locally generated and have short periods. Greater breaking-wave energy on the gap-facing slope of the salient can create shoreline and morphological asymmetry. The implication is that breakwater orientations can be designed or altered to selectively dampen or facilitate wave energy to enhance sediment transport in a desired direction, provided that breakwaters are not too far offshore and sediment availability is not restricted to affect salient formation. Adjusting exposure via gap orientation can create morphologies that cannot be inferred from process-dominant conditions.

    Within object-oriented approaches, testing has almost been ignored in favor of analysis, design, and coding. However, object-orientedness does not solve the problem of testing by itself and may even induce new problems. Most work in testing has been done with "procedure-oriented" software in mind. Traditional methods, despite their efficiency, cannot be applied without adaptation to object-oriented systems. In an object-oriented system, the basic unit of testing is a class instead of a subpr...

    Full Text Available It was the goal of this research to examine the dynamics of Croatian transformation to market orientation and test whether the market orientation model changes with time as the business environment changes. Based on the literature analysis, we proposed a hypothetical model which relies on behavioural approach in understanding market orientation. To empirically test the hypothetical model, we used data previously collected for 2001, and by replicating the same questionnaire now collected data for 2011. Data was analyzed by hierarchical regression analysis on the two sets of data. Our findings reveal that Croatian organizations reached the level of moderate market orientation leaving space for improvement. Findings also reveal that higher level of market orientation correlates with higher business performance. Furthermore, with development of ICT, the model of market orientation modified in time in a way that in predicting successful market oriented reaction, specific information on consumer satisfaction gains importance, while general information from competitor and consumer databases lose importance. Despite the changes in the relationships among the elements of market orientation, the model itself similarly predicts performance today as it did ten years ago. Managers are advised to increase implementation of market orientation especially focusing on market responsiveness as such behaviour will lead to better performance.

The dienes covered here are prepared by simple alkylation reaction or via the Claisen rearrangement or by enyne metathesis of alkyne or enyne building blocks. Here, we have also included the Diels-Alder chemistry of dendralenes, a higher analog of cross-conjugated dienes. The present article is inclusive of o-xylylene derivatives that are generated in situ starting with benzosultine or benzosulfone derivatives. The Diels-Alder reaction of these dienes with various dienophiles gave diverse polycyclic systems and biologically important targets. PMID:25875156

    The optimization of structures with respect to cost, weight or performance is a well-known application of the nonlinear optimization. However reliability-based structural optimization has been subject of only very few studies. The approaches suggested up to now have been unsatisfactory regarding general possibility of application or easy handling by user. The objective of this thesis is the development of general approaches to solve both optimization problems, the minimization of cost with respect to constraint reliabilty and the maximization of reliability under cost constraint. The extented approach of an one-level-method will be introduced in detail for the time-invariant problems. Here, the reliability of the sturcture will be analysed in the framework of the First-Order-Reliability-Method (FORM). The use of time-variant reliability analysis is necessary for a realistic modelling of many practical problems. Therefore several generalizations of the new approaches will be derived for the time-variant reliability-based structural optimization. Some important properties of the optimization problems are proved. In addition some interesting extensions of the one-level-method, for example the cost optimization of structural series systems and the cost optimization in the frame of the Second-Order-Reliabiity-Method (SORM), are presented in the thesis. (orig.) [German] Die Optimierung von Tragwerken im Hinblick auf die Kosten, das Gewicht oder die Gestalt ist eine sehr bekannte Anwendung der nichtlinearen Optimierung. Die zuverlaessigkeitsorientierte Strukturoptimierung wurde dagegen weit seltener untersucht. Die bisher vorgeschlagenen Ansaetze koennen bezueglich ihrer allgemeinen Verwendbarkeit oder ihrer nutzerfreundlichen Handhabung nicht befriedigen. Das Ziel der vorliegenden Arbeit ist nun die Entwicklung allgemeiner Ansaetze zur Loesung der beiden Optimierungsprobleme, einer Kostenminimierung unter Zuverlaessigkeitsrestriktionen und einer Zuverlaessigkeitsmaximierung bei der Beachtung einer Kostenbeschraenkung. Der erweiterte Ansatz eines Mono-Level-Verfahrens wird fuer zeitinvariante Probleme ausfuehrlich vorgestellt, wobei die Zuverlaessigkeit der Tragwerkselemente im Rahmen der Methode erster Ordnung (FORM) analysiert wird. Fuer eine realitaetsnahe Modellierung vieler praktischer Probleme ist die Verwendung zeitvarianter Zuverlaessigkeitsbetrachtungen notwendig, weshalb verschiedene Verallgemeinerungen der neuen Ansaetze fuer die zeitvariante zuverlaessigkeitsorientierte Strukturoptimierung hergeleitet werden. Einige wichtige Eigenschaften der Optimierungsprobleme werden bewiesen. Ferner werden einige interessante Erweiterungen dieses Mono-Level-Verfahrens, zum Beispiel die Kostenoptimierung von Tragwerkssystemen und die Kostenoptimierung im Rahmen der Zuverlaessigkeitsmethode zweiter Ordnung (SORM), angegeben.

    This book follows a standard tutorial approach with approximately 750 code samples spread through the 19 chapters. This amounts to over 5,900 lines of code that illustrate each concept.This book is aimed at programmers who have already learned the basics of object-oriented Python and need to write more sophisticated, flexible code that integrates seamlessly with the rest of Python. This book assumes a computer science background, with experience of common Python design patterns.

    Delta-oriented programming (DOP) is a modular approach for implementing software product lines. Delta modules generalize feature modules by allowing removal of functionality. However, DOP requires to select one particular product as core product from which all products are generated. In this paper, we propose pure deltaoriented programming (Pure DOP) that is a conceptual simplification of traditional DOP. In Pure DOP, the requirement of one designated core product is drop...
