Analyzing Learners' Language Awareness in Written Production : Product-Oriented vs. Process-Oriented Approaches  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Writing is one of the four skills that students learning a foreign language are supposed to acquire, and writing often has an important role in the language classroom. Furthermore, in the field of cultural and arts education, a process-oriented approach is considered essential for learning. However, even though we see an increased interest in emphasizing the writing process, in reality, what is often commented, discussed and graded is the final outcome - the product. Consequently, features of...

[Recovery of consciousness: process-oriented approach].  

Science.gov (United States)

Traditionally psychological neurorehabilitation of neurosurgical patients is provided subject to availability of clear consciousness and minimal potential to communicate verbally. Cognitive and emotional disorders, problems in social adaptation, neurotic syndromes are normally targets in such cases. We work with patients having survived severe brain damage being in different states of consciousness: vegetative state, minimal state of consciousness, mutism, confusion, posttraumatic Korsaroff syndrom. Psychologist considers recovery of consciousness as the target besides traditional tasks. Construction of communication with patient is central part of such job, where the patient remains unable to contact verbally, yet it is impossible to consider potential aphasia. This is a non-verbal "dialogue" with patient created by psychologist with gradual development and involving other people and objects of environment. Inline with modern neuroscientific achievements demonstrating ability to recognize by patients with severe brain injury (A. Owen, S. Laureys, M. Monti, M. Coleman, A. Soddu, M. Boly and others) we base upon psychological science, on psychotherapeutic approaches containing instruments inevitable to work with patients in altered states of consciousness and creation of non-verbal communication with patient (Jung, Reich, Alexander, Lowen, Keleman, Arnold and Amy Mindell, S. Tomandl, D. Boadella, A. Längle, P. Levin etc). This article will include 15 years of experience to apply Process-oriented approach by A. Mindell to recovery of consciousness of neurosurgical patients based on work with "minimal signals" (micro moves, breath, mimic reactions etc.), principle of feedback, psychosomatic resonance, empathy.

An object-oriented approach to energy-economic modeling  

Energy Technology Data Exchange (ETDEWEB)

In this paper, the authors discuss the experiences in creating an object-oriented economic model of the U.S. energy and agriculture markets. After a discussion of some central concepts, they provide an overview of the model, focusing on the methodology of designing an object-oriented class hierarchy specification based on standard microeconomic production functions. The evolution of the model from the class definition stage to programming it in C++, a standard object-oriented programming language, will be detailed. The authors then discuss the main differences between writing the object-oriented program versus a procedure-oriented program of the same model. Finally, they conclude with a discussion of the advantages and limitations of the object-oriented approach based on the experience in building energy-economic models with procedure-oriented approaches and languages.

THE SUCCESSION OF DATA WAREHOUSE USING OBJECT ORIENTED APPROACH  

Directory of Open Access Journals (Sweden)

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.

Risk evaluation: A cost-oriented approach  

Energy Technology Data Exchange (ETDEWEB)

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.

Increased orienting to unexpected action outcomes in schizophrenia  

Directory of Open Access Journals (Sweden)

Full Text Available Although some recent research has indicated reduced performance monitoring in patients with schizophrenia, the literature on this topic shows some remarkable inconsistencies. While most studies suggest diminished error signals following error responses, some studies reported normal post-error slowing, while others reported reduced post-error slowing. Here we review these studies and highlight the most important discrepancies. Furthermore, we argue that overall error rates are a mostly neglected issue that can at least partly explain these discrepancies. It has been reported previously that post-error slowing depends on the error rates. Participants or patients that make more errors are likely to show decreased post-error slowing. Therefore, when a group of patients is compared to a group of controls, it is extremely important to match error rates. For this purpose, we developed a procedure where we matched individuals’ error rates. In a task where subjects had to press a response key corresponding to one of four colors we manipulated the difficulty on an individual basis by varying the discriminability between the colors. Schizophrenic patients and a group of controls were tested with this procedure showing that differences in accuracy disappear. Interestingly, we can see that in patients, the color values that were needed to reach similar levels of accuracy correlate with the PANSS scale, with higher PANSS requiring more color. Most important, we found that schizophrenic patients have increased rather than decreased post-error slowing when the intertrial interval is short. This result can be interpreted within the framework of the orienting account, as it has been demonstrated previously that schizophrenic patients show increased distractibility.

Nuclear quality assurance operating philosophy: A quality-oriented approach  

International Nuclear Information System (INIS)

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

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

Approaches to outcome assessment in pulmonary rehabilitation.  

Science.gov (United States)

A comprehensive assessment is the foundation of a successful pulmonary rehabilitation programme. There is a broad selection of outcome measures that tend to be categorized into measures of exercise performance (including measures of strength) quality of life (health status), psychological well-being, nutritional status and more recently knowledge and self-efficacy. There is a growing interest in the measurement of physical activity too, although this is a current line of research activity. A sophisticated suite of outcomes allows the rehabilitation program to be personalised to the individual and deliver effective rehabilitation. PMID:24874130

An Aspect Oriented Process Based Approach To Information Risk Management  

Directory of Open Access Journals (Sweden)

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

Object Oriented Approach to Software Development for LHC Experiments  

CERN Multimedia

% RD41 \\\\ \\\\ We propose to study the viability of the Object Oriented~(OO) approach for developing the code for LHC experiments. 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.

Study of Object Oriented Analysis and Design Approach  

Directory of Open Access Journals (Sweden)

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

APPROACHES TO STUDY EDUCATIONAL AND OCCUPATIONAL TRAJECTORIES AND OUTCOMES  

Directory of Open Access Journals (Sweden)

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.

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.

Building a genome database using an object-oriented approach.  

Science.gov (United States)

GOBASE is a relational database that integrates data associated with mitochondria and chloroplasts. The most important data in GOBASE, i. e., molecular sequences and taxonomic information, are obtained from the public sequence data repository at the National Center for Biotechnology Information (NCBI), and are validated by our experts. Maintaining a curated genomic database comes with a towering labor cost, due to the shear volume of available genomic sequences and the plethora of annotation errors and omissions in records retrieved from public repositories. Here we describe our approach to increase automation of the database population process, thereby reducing manual intervention. As a first step, we used Unified Modeling Language (UML) to construct a list of potential errors. Each case was evaluated independently, and an expert solution was devised, and represented as a diagram. Subsequently, the UML diagrams were used as templates for writing object-oriented automation programs in the Java programming language. PMID:12542407

Effect of connective tissue graft orientation on the root coverage outcomes of coronally advanced flap.  

Science.gov (United States)

The aim of the present study was the evaluation of the effect of connective tissue graft orientation on clinical outcome of root coverage procedure when applied in conjunction with coronally advanced flap. Sixteen similar bilateral recession defects--Miller's class I and II--in eight patients were treated using coronally advanced flap and connective tissue graft harvested from the palate. The defects in each patient were randomly allocated to P-teeth or P-flap groups with the periosteum contacting the tooth surface or the flap, respectively. After initial scaling and root planing, acrylic templates of the treatment sites were generated. Recession depth (RD), recession width (RW), gingival sulcular depth, clinical attachment level, length of keratinized tissue, papilla width, and percentage of root coverage were measured at baseline, 1 and 3 months postoperatively. Wilcoxon and Mann-Whitney U tests were used for analyzing the data. The reduction in RD averaged 3.68 mm in P-teeth and 3.25 mm in P-flap. RW decreased 2.68 and 2.6 mm in P-teeth and P-flap, respectively. Keratinized tissue increased an average of 1.25 mm in P-teeth and 1.31 mm in P-flap. Clinical attachment gain equaled 3.87 mm for P-teeth and 3.32 mm for P-flap. All variables exhibited significant improvement compared to baseline (P 0.05). It could be concluded that while the application of connective tissue graft with coronally advanced flap is efficient for coverage of Miller's class I and II gingival recession defects, the short-term clinical outcome of this surgical method is not affected by orientation of connective tissue graft.

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.))

A Distributed Trajectory-Oriented Approach to Managing Traffic Complexity  

Science.gov (United States)

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

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

DEFF Research Database (Denmark)

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 â??related productsâ?? for manufacturers of furniture. A â??related textile productâ?? 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 â??emotional valueâ?? 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 â??programmatic approachâ?? 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 â??exemplaryâ?? and the research contributions are presented as â??exemplarsâ??, â??frameworksâ??, â??toolsâ?? and â??structuresâ??, 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 â??overall challengesâ?? and â??research questionsâ??. I view this thesis as a research contribution which facilitates a programmatic approach to a project such as this one. The â??overall challengesâ?? (challenges within the field of textile design) is a constant variable against which the programme (challenges which Gabrielâ??s textile designers face) can be benchmarked. Thus the â??research questionsâ?? (emotional value and user and stakeholder involvement) are â??shapableâ?? 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 Schönâ??s definition of design as â??a conversation with the materials of a situationâ??. Subsequently, through design experiments involving several participants, I develop the â??Tripod Approachâ??â?? 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 â?? based on Jesse Prinzâ??s and Antonio Damasioâ??s emotion research â?? for a perception of emotional value of applied textiles which acknowledges bodily feedback as a core concept in the process which leads to â??emotionâ??. This approach is used when exploring and adjusting Patrick Jordanâ??s framework of â??the four pleasuresâ?? to the study of emotional value of applied textiles as presented in this thesis. My expe

Analyzing Web Service Contracts : an aspect oriented approach  

DEFF Research Database (Denmark)

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

Ultra Low Power Signal Oriented Approach for Wireless Health Monitoring  

Directory of Open Access Journals (Sweden)

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

Client Oriented Approach for Assisting Business Improvement Decision Making  

Directory of Open Access Journals (Sweden)

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.

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

Directory of Open Access Journals (Sweden)

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.

A Kalman-Filter-Based Approach to Combining Independent Earth-Orientation Series  

Science.gov (United States)

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

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

Towards a user-oriented analytical approach to learning design  

Directory of Open Access Journals (Sweden)

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.

A Task-oriented Approach for Hydrogeological Site Characterization  

Science.gov (United States)

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.

Information-related complexity: a problem-oriented approach  

CERN Multimedia

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

The influence of approach-avoidance motivational orientation on conflict adaptation.  

Science.gov (United States)

To deal effectively with a continuously changing environment, our cognitive system adaptively regulates resource allocation. Earlier findings showed that an avoidance orientation (induced by arm extension), relative to an approach orientation (induced by arm flexion), enhanced sustained cognitive control. In avoidance conditions, performance on a cognitive control task was enhanced, as indicated by a reduced congruency effect, relative to approach conditions. Extending these findings, in the present behavioral studies we investigated dynamic adaptations in cognitive control-that is, conflict adaptation. We proposed that an avoidance state recruits more resources in response to conflicting signals, and thereby increases conflict adaptation. Conversely, in an approach state, conflict processing diminishes, which consequently weakens conflict adaptation. As predicted, approach versus avoidance arm movements affected both behavioral congruency effects and conflict adaptation: As compared to approach, avoidance movements elicited reduced congruency effects and increased conflict adaptation. These results are discussed in line with a possible underlying neuropsychological model. PMID:24841080

Approach/Avoidance Orientations Affect Self-Construal and Identification with In-group.  

Science.gov (United States)

Approach and avoidance are two basic motivational orientations. Their activation influences cognitive and perceptive processes: Previous work suggests that an approach orientation instigates a focus on larger units as compared to avoidance. Study 1 confirms this assumption using a paradigm that more directly taps a person's tendency to represent objects as belonging to small or large units than prior studies. It was further predicted that the self should also be represented as belonging to larger units, and hence be more interdependent under approach than under avoidance. Study 2 supports this prediction. As a consequence of this focus on belonging to larger units, it was finally predicted that approach results in a stronger identification with one's in-group than avoidance. Studies 3 and 4 support that prediction. PMID:22844229

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

DEFF Research Database (Denmark)

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.

A Laplacian approach to multi-oriented text detection in video.  

Science.gov (United States)

In this paper, we propose a method based on the Laplacian in the frequency domain for video text detection. Unlike many other approaches which assume that text is horizontally-oriented, our method is able to handle text of arbitrary orientation. The input image is first filtered with Fourier-Laplacian. K-means clustering is then used to identify candidate text regions based on the maximum difference. The skeleton of each connected component helps to separate the different text strings from each other. Finally, text string straightness and edge density are used for false positive elimination. Experimental results show that the proposed method is able to handle graphics text and scene text of both horizontal and nonhorizontal orientation. PMID:20733217

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

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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

A new approach for the design of electric power system software using object oriented modeling  

Energy Technology Data Exchange (ETDEWEB)

This work presents a new approach for the development of software for power systems, using object oriented modeling (OOM). The definition of class structures to represent power systems follows strictly the OOM paradigm and includes the reuse of well-tested software employed by electric utilities. The physical elements are classified as structural and composition elements, defining different modeling abstractions. Their physical and functional characteristics are grouped in distinct abstractions. The modeling of the physical elements of the power systems is independent of the applications to be designed. Object oriented design patterns are used to determine the structures, allowing that new functions be easily added to the structures, minimizing the impact on the existing class structure. This adds flexibility to the model, facilitating the integrated development of computing tools for the industry. A computational tool including a load-flow and a dynamics simulation application, developed according to the proposed approach, is presented. (author)

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

International Nuclear Information System (INIS)

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

Modeling habitat suitability for moose in coastal northern Sweden: empirical vs process-oriented approaches.  

Science.gov (United States)

Habitat models may provide viable tools for co-management of large ungulates and forest resources, yet their applicability has not been comprehensively evaluated in managed forest. We examined 2 inherently different approaches to model the relative winter habitat suitability for moose (Alces alces) in the coastal area of northern Sweden. An empirical approach based on GPS positions of 15 female moose was used to scrutinize the assumptions and functional mechanisms of a process-oriented, conceptual approach, based on published material on the species' preferences for habitat components related to food and cover. For both model approaches habitat was described using estimates of forest-stand characteristics based on satellite imagery. The empirical model also included variables relating to topographic properties of the landscape as well as distances to landscape features. The output from both models was a habitat suitability index (HSI) score, enabling the models to be compared with each other. The models showed different results, highlighting the need to include the spatially explicit distribution of environmental variables in future conceptual, process-oriented models. PMID:15049352

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

Science.gov (United States)

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 paper presents an object oriented fault diagnostic expert system framework which analyses observations from the unit under test when fault occurs and infers the causes of failures. The frame work is characterized by two basic features. The first includes a fault diagnostic strategy which utilizes the fault classification and checks knowledge about unit under test. The fault classification knowledge reduces the complexity in fault diagnosis by partitioning the fault section. The second characteristic is object oriented inference mechanism using backward chaining with message passing within objects. The refractoriness and recency property of inference mechanism improve efficiency in fault diagnosis. The developed framework demonstrates its effectiveness and superiority compared to earlier approaches

A goal-oriented adaptive finite-element approach for plane wave 3-D electromagnetic modelling  

Science.gov (United States)

We have developed a novel goal-oriented adaptive mesh refinement approach for finite-element methods to model plane wave electromagnetic (EM) fields in 3-D earth models based on the electric field differential equation. To handle complicated models of arbitrary conductivity, magnetic permeability and dielectric permittivity involving curved boundaries and surface topography, we employ an unstructured grid approach. The electric field is approximated by linear curl-conforming shape functions which guarantee the divergence-free condition of the electric field within each tetrahedron and continuity of the tangential component of the electric field across the interior boundaries. Based on the non-zero residuals of the approximated electric field and the yet to be satisfied boundary conditions of continuity of both the normal component of the total current density and the tangential component of the magnetic field strength across the interior interfaces, three a-posterior error estimators are proposed as a means to drive the goal-oriented adaptive refinement procedure. The first a-posterior error estimator relies on a combination of the residual of the electric field, the discontinuity of the normal component of the total current density and the discontinuity of the tangential component of the magnetic field strength across the interior faces shared by tetrahedra. The second a-posterior error estimator is expressed in terms of the discontinuity of the normal component of the total current density (conduction plus displacement current). The discontinuity of the tangential component of the magnetic field forms the third a-posterior error estimator. Analytical solutions for magnetotelluric (MT) and radiomagnetotelluric (RMT) fields impinging on a homogeneous half-space model are used to test the performances of the newly developed goal-oriented algorithms using the above three a-posterior error estimators. A trapezoidal topographical model, using normally incident EM waves at both MT and RMT frequencies, is adopted to further test the convergence of the newly developed algorithms against a surface integral approach. Next, the 3D-1 benchmark model from the COMMEMI project is used to show the efficiency of the goal-oriented adaptive algorithm and to compare our solutions against volume integral solutions and other finite-element solutions. For all three test cases, we found that the error estimator using face jumps of normal components of current density embedded in the goal-oriented adaptive refinement procedure shows the most robust performance.

Market oriented new product development: How can a means-end chain approach affect the process?  

DEFF Research Database (Denmark)

Few disagree on the advantage of market oriented product development. However, can a well-known theory on consumer behaviour be used as a catalyst for achieving it? This paper describes a case study where means-end chain (MEC) approach was introduced to a cross-functional development team at two different stages of the development process. 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 results also indicate that MEC data are most valuable to the team in the early stages of development process.

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

Early experience of robotic-assisted inguinal lymphadenectomy: review of surgical outcomes relative to alternative approaches.  

Science.gov (United States)

Inguinal lymph node dissection is a diagnostic and potentially curative treatment for penile carcinoma, which has historically been associated with high morbidity rates. This review summarizes the initial outcomes of robotic-assisted inguinal lymphadenectomy (RAIL) compared with the outcomes of the standard open and endoscopic approaches. The early experience suggests that RAIL may yield comparable oncologic outcomes, although future prospective studies of RAIL with greater numbers of participants and long-term follow-up are needed to evaluate the incidence and severity of perioperative and postoperative complications.

Outcome Measurement in Economic Evaluations of Public Health Interventions: a Role for the Capability Approach?  

Directory of Open Access Journals (Sweden)

Full Text Available Public health interventions have received increased attention from policy makers, and there has been a corresponding increase in the number of economic evaluations within the domain of public health. However, methods to evaluate public health interventions are less well established than those for medical interventions. Focusing on health as an outcome measure is likely to underestimate the impact of many public health interventions. This paper provides a review of outcome measures in public health; and describes the benefits of using the capability approach as a means to developing an all encompassing outcome measure.

Supravalvar aortic stenosis: current surgical approaches and outcomes.  

Science.gov (United States)

Supravalvar aortic stenosis (SVAS) is a congenital anomaly characterized by a discrete or diffuse narrowing of the ascending aorta. It may also be associated with right-ventricular outflow tract obstruction, aortic valve pathology and coronary ostial stenosis. While present in both familial and sporadic forms, it demonstrates a strong association with William-Beuren syndrome, both being anomalies associated with defects in the elastin gene. In this article, the authors have discussed the etiology, morphology, clinical presentation and genetic basis of SVAS. Various surgical approaches, both conventional and recent, have been discussed and demonstrated with the aid of diagrams. Single-, two- and three-sinus methods have been presented, along with a comparative analysis of early results, associated procedures, late mortality and reoperation. In conclusion, the authors have described their institutional experience of more than 40 years in the surgical management of SVAS. PMID:23895031

A pragmatic dose-finding approach using short-term surrogate efficacy outcomes to evaluate binary efficacy and toxicity outcomes in phase I cancer clinical trials.  

Science.gov (United States)

There is a growing need for study designs that can evaluate efficacy and toxicity outcomes simultaneously in phase I or phase I/II cancer clinical trials. Many dose-finding approaches have been proposed; however, most of these approaches assume binary efficacy and toxicity outcomes, such as dose-limiting toxicity (DLT), and objective responses. DLTs are often defined for short time periods. In contrast, objective responses are often defined for longer periods because of practical limitations on confirmation and the criteria used to define 'confirmation'. This means that studies have to be carried out for unacceptably long periods of time. Previous studies have not proposed a satisfactory solution to this specific problem. Furthermore, this problem may be a barrier for practitioners who want to implement notable previous dose-finding approaches. To cope with this problem, we propose an approach using unconfirmed early responses as the surrogate efficacy outcome for the confirmed outcome. Because it is reasonable to expect moderate positive correlation between the two outcomes and the method replaces the surrogate outcome with the confirmed outcome once it becomes available, the proposed approach can reduce irrelevant dose selection and accumulation of bias. Moreover, it is also expected that it can significantly shorten study duration. Using simulation studies, we demonstrate the positive utility of the proposed approach and provide three variations of it, all of which can be easily implemented with modified likelihood functions and outcome variable definitions.

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

International Nuclear Information System (INIS)

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

SESAME: An event driven approach for modeling object-oriented communication software systems  

Energy Technology Data Exchange (ETDEWEB)

The Object-Oriented (OO) paradigm represents a significant shift in approach to the development of complex software systems. The OO approach provides a very natural solution, where entities in the system have close association with the problem domain. However the application of the approach suffers from a major draw back - the lack of well defined methods for visualizing objects which map well to the problem domain. The very first activity of object identification itself has for a long time been more of an art than science. Object identification in the case of some problem domains (like communication network protocols etc.) is even more difficult as they are more abstract and cannot be easily related to the real world objects. The proposed method SESAME (Scenario Event State Action MEthod) builds a solution to the problems based on events that occur in the system. whether they are generated by people. machines or components of the software. It approaches the problem domains by looking at scenarios which are characterized by events, states, and actions. This approach helps in adopting an organized way of visualizing the entities that need to participate in the system. Abstraction of these entities into objects will then be relatively simple. The SESAME method features a comprehensive Analysis and Specification activity which comprises of building an Object Behavioral Model (OBM) and a Class Specification Model (CSM). The analysis is taken through by tracing the events and their responses in every visualizable scenario.

An exploration of FMCDM approach for evaluating the outcome/success of GSD projects  

Science.gov (United States)

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

Market-oriented new product development: How can a means-end chain approach affect the process?  

DEFF Research Database (Denmark)

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.

Decomposed Approach of Market Orientation and Marketing Mix Capability: Research on Their Relationships with Firm Performance in the Korean Context  

Directory of Open Access Journals (Sweden)

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.

Individual factors and GP approach as predictors for the outcome of rehabilitation among long-term sick listed cases  

DEFF Research Database (Denmark)

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

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

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

DEFF Research Database (Denmark)

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 â?? CS#1), a rule-based feedback control (CS#2), and a feedforwardâ??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.

Applying Business Process Oriented Learning in Industry: The PROLIX Solution Approach Based on a Case Study  

Directory of Open Access Journals (Sweden)

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

The long and bumpy road to outcome-oriented management of long-term care in Germany: implementation of the Resident Assessment Instrument in home-care services.  

Science.gov (United States)

OBJECTIVE: Although the quality of long-term care has improved, many problems still remain, and better processes seem to be necessary. Hence, outcome-oriented management is of particular importance. The Resident Assessment Instrument (RAI) is a tool that has been used successfully in many countries to improve quality of care. However, there are problems of implementation and it lacks information on the conditions of successful or failing information of the RAI. The aim of this article is to find out to what extent technical/qualification requirements help to introduce or lead to failure of the implementation of an assessment instrument like RAI. METHODS: Therefore, a cluster randomized controlled trial showed services using RAI intensively tend to have better outcomes after 12?months. But the effects depend on the success of the implementation. Using a factor analysis, an index was built to divide the care providers into "optimal" and "suboptimal" RAI users. RESULTS: Some factors that seem to lead to a rather successful implementation could be detected: A higher proportion of qualified staff, a lower perceived quantitative workload, a small size of care providers, the type of ownership (for-profit) and a late entry in study [Correction made here after initial online publication.]. CONCLUSION: The success or failure of the implementation of an outcome-oriented control instrument is determined by professional, organizational restrictions. The results show that a better implementation leads to better outcomes for clients. Copyright © 2013 John Wiley & Sons, Ltd. PMID:23671001

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

Directory of Open Access Journals (Sweden)

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.

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)

Detecting Slums from Quick Bird Data in Pune Using AN Object Oriented Approach  

Science.gov (United States)

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

Closing the Black-White gap in birth outcomes: a life-course approach.  

Science.gov (United States)

In the United States, Black infants have significantly worse birth outcomes than White infants. Over the past decades, public health efforts to address these disparities have focused primarily on increasing access to prenatal care, however, this has not led to closing the gap in birth outcomes. We propose a 12-point plan to reduce Black-White disparities in birth outcomes using a life-course approach. The first four points (increase access to interconception care, preconception care, quality prenatal care, and healthcare throughout the life course) address the needs of African American women for quality healthcare across the lifespan. The next four points (strengthen father involvement, systems integration, reproductive social capital, and community building) go beyond individual-level interventions to address enhancing family and community systems that may influence the health of pregnant women, families, and communities. The last four points (close the education gap, reduce poverty, support working mothers, and undo racism) move beyond the biomedical model to address the social and economic inequities that underlie much of health disparities. Closing the Black-White gap in birth outcomes requires a life course approach which addresses both early life disadvantages and cumulative allostatic load over the life course. PMID:20629248

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

Science.gov (United States)

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.

Diversity of approaches to classic galactosemia around the world: a comparison of diagnosis, intervention, and outcomes.  

Science.gov (United States)

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

Targeting Oncogenic Protein-Protein Interactions by Diversity Oriented Synthesis and Combinatorial Chemistry Approaches  

Directory of Open Access Journals (Sweden)

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.

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

Energy Technology Data Exchange (ETDEWEB)

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

Clinical outcomes of minimally invasive endoscopic and conventional sternotomy approaches for atrial septal defect repair  

Science.gov (United States)

Background Concerns remain that minimally invasive atrial septal defect (ASD) repair may compromise patient outcomes. We compared clinical outcomes of adult patients undergoing ASD repair via a minimally invasive endoscopic approach versus a “gold standard” sternotomy. Methods We retrospectively reviewed the clinical outcomes of consecutive patients who underwent ASD patch repair at our institution between 2002 and 2012. We compared in-hospital/30-day mortality, postoperative complications, length of stay in hospital and in the intensive care unit and blood product requirements between patients who underwent right mini-thoracotomy (MT) and those who underwent conventional sternotomy. Results During the study period, 73 consecutive patients underwent ASD patch repair at our institution: 51 (age 47 ± 16 yr, 66.7% women) in the MT group and 22 (age 46 ± 21 yr, 59.1% women) in the sternotomy group. In-hospital mortality was similar between the 2 groups (MT 0% v. sternotomy 4.5%, p = 0.30). There were no significant differences in any postoperative complications or blood product requirements. No patients in the MT group suffered stroke, retrograde aortic dissection or leg ischemia. Mean intensive care unit (MT 1.2 ± 1.2 d v. sternotomy 1.7 ± 2.2 d, p = 0.26) and hospital length of stays (MT 5.1 ± 2.2 d v. sternotomy 6.3 ± 3.6 d, p = 0.17) were similar between the groups; however, there was a trend toward fewer patients requiring prolonged hospital stays (> 10 d) in the MT group (3.9% v. 18.2%, p = 0.06). Conclusion Repair of ostium secundum and sinus venosus ASD can be performed safely via MT endoscopic approach with similar outcomes as sternotomy. Patient preference for a more cosmetically appealing incision may be considered without concern of compromised outcomes.

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

Directory of Open Access Journals (Sweden)

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.

Pragmatic approach to visual serving of robots in a vision-oriented workcell  

Science.gov (United States)

The applications of robots in automating assembly tasks has been hampered by an inability to overcome problems of operation of robots within an unstructured and unconstrained environment at an acceptable cost and performance. Such operations necessitate the integration of high-level sensory capabilities -- and in particular vision sensing -- into the overall control system at various levels in the control hierarchy. The paper summarizes the past and present approaches to robot guidance using vision from the perspective of a classification due to Sanderson and Weiss. A two pronged approach is suggested as a promising strategy towards integrating vision into a robot for visual servoing. That is to directly feed back vision derived spatial information (optimized for robot position control) into a robot controller cast in task or operational space and to use vision as a primary sensor medium for all critical spatial measurement tasks in the workspace. This offers the potential for low-cost high performance vision servoing through a greatly reduced reliance on the fidelity of the individual components. The paper presents this new strategy for visual guidance supported by experimental results, which is based on a new model of natural vision systems and upon a strategy which addresses the identified performance needs of the diverse vision tasks within a vision oriented robotic workcell. A practical implementation of this generalized approach has been developed which offers sub-pixel resolution operation at low cost. This system has, in turn, been integrated into a direct vision feedback control application (involving a two-link rig and on 2 degrees of freedom of a PUMA560 arm) and has been used to demonstrate the execution of pick-and-place type tasks. Hence end-effector placement has been demonstrated with the positioning accuracy limit imposed by the camera, and significant robustness to kinematic model and vision calibration errors being observed. Overall, therefore it is shown that low-cost direct vision feedback is possible and that it can offer significant improvements over existing strategies.

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.

Microscopic versus open approach to craniosynostosis: a long-term outcomes comparison.  

Science.gov (United States)

The purpose of this retrospective study was to evaluate the long-term outcomes of using the microscopic minimally invasive approach for the treatment of nonsyndromic craniosynostosis. During the last 10 years, 180 consecutive patients with nonsyndromic craniosynostosis were treated: 67 patients were treated with microscopic minimally invasive approach, and 113 were treated with the open approach. In the microscopic group, there was 1 intraoperative complication (1.5%). There were 10 postoperative complications (14.9%), of which 9 required major reoperations and 1 required a minor procedure. The major complications occurred in 7 unicoronal patients (58.3%) and 2 metopic patients (25.0%). In the open-approach group, there were 8 complications (7.1%), 2 patients required major reoperations and 6 required minor procedures. Chi-squared test showed that there was no statistically significant difference in the overall complication rate between the microscopic and open approaches. However, in the unicoronal patients, the complication rate was significantly higher in the microscopic group (P < 0.001). In conclusion, the microscopic approach is our treatment of choice in nonsyndromic patients with sagittal and lambdoidal craniosynostosis. We no longer use the microscopic approach in patients with unicoronal or metopic craniosynostosis because of the high complication rate. PMID:25006905

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

Directory of Open Access Journals (Sweden)

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.

Integrated Approach for Improving Small Scale Market Oriented Dairy Systems in Pakistan: Economic Impact of Interventions  

Directory of Open Access Journals (Sweden)

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

The Surgical Approaches of Cervical Spondylotic Myelopathy and the Predictive Factors for the Surgical Outcomes  

Directory of Open Access Journals (Sweden)

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.

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

Science.gov (United States)

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

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

Mini-midvastus versus mini-medial parapatellar approach for minimally invasive total knee arthroplasty: outcomes pendulum is at equilibrium.  

Science.gov (United States)

Comparisons between mini-midvastus (mMV) and mini-medial parapatellar approach (mMPP) for total knee arthroplasty (TKA) have reported variable results. We compared two approaches with minimum two year follow up. Forty consecutive patients who underwent staged bilateral TKA were prospectively randomized for mMPP approach in one knee and mMV approach in the other. Clinical parameters (muscle strength, pain, ROM, Knee Society Score) and surgic.l parameters (duration of surgery, blood loss, lateral releases) were assessed at 2, 6, 12 weeks and 6, 12, 24 months postoperatively. Clinical outcomes revealed inconsistent pattern of differences at various intervals. Surgical outcomes were not different. There were no major differences in outcomes between the two approaches. We recommend someone use surgical approach with which they are most familiar. PMID:23790343

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

Directory of Open Access Journals (Sweden)

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.

Object-oriented approach to modeling and analysis of truss structures  

Science.gov (United States)

Object-oriented structural and geometric analysis methods for truss structures are proposed. The methods are based on the iterative relaxation of nodal unbalanced forces by moving the nodes. The entities appeared in truss analysis are modeled as classes and their class hierarchy is established. The knowledges for a truss node, a truss member, a material, a sectional shape of the member are extracted and constructed as a knowledge base in an object-oriented manner. The object-oriented structural analysis is found to be valid for material and geometric nonlinearities, and the object-oriented geometric analysis where a kinematic problem is converted into a problem for a force equilibrium at the nodes, is also found to be effective for determining the geometry of variable geometry trusses. The whole system is written in an object-oriented language. Smalltalk, and several results on structural and geometric analysis are presented. The speed of the computation is discussed along with the size of the structures and the over-relaxation factor. The extension of the knowledge base is also discussed.

A technique based on measurement of change in natural frequencies and modeling of crack by rotational spring is employed to detect a crack with straight front in different orientations in a section of straight horizontal steel hollow pipe (outer diameter 0.0378 m and inner diameter 0.0278 m). Crack orientations in the range 0-60° with the vertical have been examined and sizes/depths in the range 1-4 mm through the wall of thickness 5 mm have been studied. Variation of rotational spring stiffness with crack size and orientation has been obtained experimentally by deflection and vibration methods. The spring stiffness reduces as expected, with an increase in crack size; it increases with an increase in the crack orientation angle. The crack location has been predicted with a maximum error of 7.29%. The sensitivity of the method for prediction of crack location on variations in experimental data has been examined by changing the difference between the frequencies of pipes with and without crack by ±10%. The method is found to be very robust; the maximum variation in location is 2.68%, which is much less than the change in frequency difference introduced.

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

Science.gov (United States)

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.

Effects of Task-oriented Approach on Affected Arm Function in Children with Spastic Hemiplegia Due to Cerebral Palsy  

Science.gov (United States)

[Purpose] The purpose of the present study was to examine the effects of task-oriented approach on motor function of the affected arm in children with spastic hemiplegia due to cerebral palsy. [Subjects] Twelve children were recruited by convenience sampling from 2 local rehabilitation centers. The present study utilized a one-group pretest-posttest design. All of children received task-oriented training for 6 weeks (40?min/day, 5 days/week) and also underwent regular occupational therapy. Three clinical tests, Box and Block Test (BBT), Manual Ability Measure (MAM-16), and Wee Functional Independence Measure (WeeFIM) were performed 1 day before and after training to evaluate the effects of the training. [Results] Compared with the pretest scores, there was a significant increase in the BBT, MAM-16, and WeeFIM scores of the children after the 6-week practice period. [Conclusion] The results of this study suggest that a task-oriented approach to treatment of the affected arm improves functional activities, such as manual dexterity and fine motor performance, as well as basic daily activities of patients with spastic hemiplegia due to cerebral palsy.

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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.

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

CERN Document Server

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).

“Identifying the Quality of Object Oriented Software System using Modularization Approach  

Directory of Open Access Journals (Sweden)

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

Effect of surgical approach on the early outcome of total hip replacement for femoral neck fractures.  

Science.gov (United States)

We reviewed the short-term outcome of 171 patients treated with total hip replacement for femoral neck fractures using the lateral (94 patients) or posterior approach (77 patients). The Sernbo score and the Abbreviated Mental Test Score were used to assess patients' pre-injury functional and cognitive status respectively. Patients were uniformly treated with regard to the type of prosthesis, size of femoral head and rehabilitation. They were followed up to a mean of 25 months (range : 13-42 months). The dislocation rate in the lateral group was 2.1% versus 0% in the posterior group. There was no difference with regards to leg length discrepancy and the restoration of medial offset. Our results were attributed the standardised patients' selection and adequate soft tissue repair. PMID:24563972

Assessment of clinical outcomes in breast cancer patients treated with taxanes: multi-analytical approach.  

Science.gov (United States)

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

COMO An approach to Object Oriented Analysis and Design for High Energy Physics applications of algorithmic nature  

CERN Document Server

The emergence of the Object Oriented technology is having major consequences on the evolution of the software for High Energy Physics. Given the lack of maturity of the commercial products currently available, it is too early to make a statement on which OO languages and methodologies will survive up to the start of the Large Hadron Collider. The opinion of the author is that many traditional design features successfully tested during the last two decades are rather independent from any specific language characteristics. They still appear as valuable and could be seamlessly transposed into the Object world. They constitute the skeleton of the COMO approach presented in this note.

A Development-Oriented IS Evaluation Approach: Case Demonstration for DSS  

Directory of Open Access Journals (Sweden)

Full Text Available Information systems (IS development research needs a broader conceptual lens for evaluating IS design qualities. Most conventional IS evaluation approaches are focused on narrow objectives, such as the process and content rather than the development process as a whole. This paper describes a qualitative evaluation of a new approach that extends evaluation strategies to incorporate development phases, specifically within decision support systems (DSS development. The conceptual approach is based on a mental model from the design science research paradigm and evaluates DSS development at various design checkpoints. This paper also describes qualitative findings on the applicability of the conceptual approach in a socio-technical design context.

Object-oriented approach to the automatic segmentation of bones from pediatric hand radiographs  

Science.gov (United States)

The purpose of this paper is to develop a robust and accurate method that automatically segments phalangeal and epiphyseal bones from digital pediatric hand radiographs exhibiting various stages of growth. The development of this system draws principles from object-oriented design, model- guided analysis, and feedback control. A system architecture called 'the object segmentation machine' was implemented incorporating these design philosophies. The system is aided by a knowledge base where all model contours and other information such as age, race, and sex, are stored. These models include object structure models, shape models, 1-D wrist profiles, and gray level histogram models. Shape analysis is performed first by using an arc-length orientation transform to break down a given contour into elementary segments and curves. Then an interpretation tree is used as an inference engine to map known model contour segments to data contour segments obtained from the transform. Spatial and anatomical relationships among contour segments work as constraints from shape model. These constraints aid in generating a list of candidate matches. The candidate match with the highest confidence is chosen to be the current intermediate result. Verification of intermediate results are perform by a feedback control loop.

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

Directory of Open Access Journals (Sweden)

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.

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

Directory of Open Access Journals (Sweden)

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

Searching for the Definition of Macrosomia through an Outcome-Based Approach  

Science.gov (United States)

Background Macrosomia has been defined in various ways by obstetricians and researchers. The purpose of the present study was to search for a definition of macrosomia through an outcome-based approach. Methods In a study of 30,831,694 singleton term live births and 38,053 stillbirths in the U.S. Linked Birth-Infant Death Cohort datasets (1995–2004), we compared the occurrence of stillbirth, neonatal death, and 5-min Apgar score less than four in subgroups of birthweight (4000–4099 g, 4100–4199 g, 4200–4299 g, 4300–4399 g, 4400–4499 g, 4500–4999 g vs. reference group 3500–4000 g) and birthweight percentile for gestational age (90th–94th percentile, 95th-96th, and ?97th percentile, vs. reference group 75th–90th percentile). Results There was no significant increase in adverse perinatal outcomes until birthweight exceeded the 97th percentile. Weight-specific odds ratios (ORs) elevated substantially to 2 when birthweight exceeded 4500 g in Whites. In Blacks and Hispanics, the aORs exceeded 2 for 5-min Apgar less than four when birthweight exceeded 4300 g. For vaginal deliveries, the aORs of perinatal morbidity and mortality were larger for most of the subgroups, but the patterns remained the same. Conclusions A birthweight greater than 4500 g in Whites, or 4300 g in Blacks and Hispanics regardless of gestational age is the optimal threshold to define macrosomia. A birthweight greater than the 97th percentile for a given gestational age, irrespective of race is also reasonable to define macrosomia. The former may be more clinically useful and simpler to apply.

Innovative Community-Based Approaches Doubled Tuberculosis Case Notification and Improve Treatment Outcome in Southern Ethiopia  

Science.gov (United States)

Background TB Control Programmes rely on passive case-finding to detect cases. TB notification remains low in Ethiopia despite major expansion of health services. Poor rural communities face many barriers to service access. Methods and Findings A community-based intervention package was implemented in Sidama zone, Ethiopia. The package included advocacy, training, engaging stakeholders and communities and active case-finding by female Health Extension Workers (HEWs) at village level. HEWs conducted house-to-house visits, identified individuals with a cough for two or more weeks, with or without other symptoms, collected sputum, prepared smears and supervised treatment. Supervisors transported smears for microscopy, started treatment, screened contacts and initiated Isoniazid preventive therapy (IPT) for children. Outcomes were compared with the pre-implementation period and a control zone. Qualitative research was conducted to understand community and provider perceptions and experiences. HEWs screened 49,857 symptomatic individuals (60% women) from October 2010 to December 2011. 2,262 (4·5%) had smear-positive TB (53% women). Case notification increased from 64 to 127/100,000 population/year resulting in 5,090 PTB+ and 7,071 cases of all forms of TB. Of 8,005 contacts visited, 1,949 were symptomatic, 1,290 symptomatic were tested and 69 diagnosed with TB. 1,080 children received IPT. Treatment success for smear-positive TB increased from 77% to 93% and treatment default decreased from 11% to 3%. Service users and providers found the intervention package highly acceptable. Conclusions Community-based interventions made TB diagnostic and treatment services more accessible to the poor, women, elderly and children, doubling the notification rate and improving treatment outcome. This approach could improve TB diagnosis and treatment in other high burden settings.

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

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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.

A Model Transformation Approach to Derive Architectural Models from Goal-Oriented Requirements Models  

Science.gov (United States)

Requirements engineering and architectural design are key activities for successful development of software systems. Both activities are strongly intertwined and interrelated, but many steps toward generating architecture models from requirements models are driven by intuition and architectural knowledge. Thus, systematic approaches that integrate requirements engineering and architectural design activities are needed. This paper presents an approach based on model transformations to generate architectural models from requirements models. The source and target languages are respectively the i* modeling language and Acme architectural description language (ADL). A real web-based recommendation system is used as case study to illustrate our approach.

An object-oriented approach to risk and reliability analysis : methodology and aviation safety applications.  

Energy Technology Data Exchange (ETDEWEB)

This article describes how features of event tree analysis and Monte Carlo-based discrete event simulation can be combined with concepts from object-oriented analysis to develop a new risk assessment methodology, with some of the best features of each. The resultant object-based event scenario tree (OBEST) methodology enables an analyst to rapidly construct realistic models for scenarios for which an a priori discovery of event ordering is either cumbersome or impossible. Each scenario produced by OBEST is automatically associated with a likelihood estimate because probabilistic branching is integral to the object model definition. The OBEST methodology is then applied to an aviation safety problem that considers mechanisms by which an aircraft might become involved in a runway incursion incident. The resulting OBEST model demonstrates how a close link between human reliability analysis and probabilistic risk assessment methods can provide important insights into aviation safety phenomenology.

The Object Oriented Approach to Machine Physics Calculations with Java Technology  

CERN Multimedia

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...

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

Science.gov (United States)

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).

German Orientalism  

Directory of Open Access Journals (Sweden)

Full Text Available Review of: Suzanne L. Marchand, German Orientalism in the Age of Empire: Religion, Race and Scholarship, Cambridge and Washington, D.C.: Cambridge University Press, 2009. This analysis of Suzanne L. Marchand’s German Orientalism in the Age of Empire: Religion, Race and Scholarship reads her contribution in part against the background of Edward Said’s path breaking book Orientalism. Differences lie in her more expansive understanding of the term ‘Oriental’ to include the Far East and her concentration on German scholarship. Approaches to Orientalist scholarship are often judgmental. Marchand complicates the discourse by speaking to the individual and institutional circumstances, and not overestimating the effect that scholars have when they talk truth, or even merely ideas, to power. Her treatment of scholarship of visual art and of Jewish learning are the areas that could benefit from more nuanced thought and more research.

Disrupting the downward spiral of chronic pain and opioid addiction with mindfulness-oriented recovery enhancement: a review of clinical outcomes and neurocognitive targets.  

Science.gov (United States)

ABSTRACT Prescription opioid misuse and addiction among chronic pain patients are problems of growing medical and social significance. Chronic pain patients often require intervention to improve their well-being and functioning, and yet, the most commonly available form of pharmacotherapy for chronic pain is centered on opioid analgesics-drugs that have high abuse liability. Consequently, health care and legal systems are often stymied in their attempts to intervene with individuals who suffer from both pain and addiction. As such, novel, nonpharmacologic interventions are needed to complement pharmacotherapy and interrupt the cycle of behavioral escalation. The purpose of this paper is to describe how the downward spiral of chronic pain and prescription opioid misuse may be targeted by one such intervention, Mindfulness-Oriented Recovery Enhancement (MORE), a new behavioral treatment that integrates elements from mindfulness training, cognitive-behavioral therapy, and positive psychology. The clinical outcomes and neurocognitive mechanisms of this intervention are reviewed with respect to their effects on the risk chain linking chronic pain and prescription opioid misuse. Future directions for clinical and pharmacologic research are discussed. PMID:24845547

Green Buildings in Denmark â?? From radical ecology to consumer oriented market approaches?  

DEFF Research Database (Denmark)

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.

Architectural approaches to the design of LISP-oriented reduced-instruction set machines  

Energy Technology Data Exchange (ETDEWEB)

The Reduced Instruction Set Computers (RISC) architectural concept was applied to the Artificial Intelligence (AI) applications, namely, the List Processing language, LISP. The study investigates the most important aspects of the RISC architecture (i.e., Instruction Set, Call/Return Mechanism, and Pipeline Organization). These architectural features are, then, tailored to fit the nature the LISP language. Thus a software tool was developed to experiment with the dynamic execution of many programs determined to represent the LISP language applications in artificial intelligence. The most-frequently used machine instructions were found, and an instruction set for a new RISC-oriented LISP was proposed based on these results. A complete analysis of the frequency of memory and register usage by LISP programs, as well as the frequency of different addressing modes, is presented. It was found that Call/Return operations consumed more than 50% of the total execution time of LISP programs due to the recursive nature of LISP. This factor prompted the study and development of an efficient Call/Return mechanism designed especially for LISP execution. An Overlapping Register Windows (ORW) scheme was introduced, and a replacement strategy was found as a result of simulating the ORW.

Approach to HIR (human-oriented information restructuring) using bird's-eye views  

Science.gov (United States)

In this paper, we describe a system that creates a virtual bird's-eye view from multi-camera images in real-time and its application to 'HIR (Human-Oriented Information Restructuring) system for ITS' we have proposed. In recent years, studies on AHS (Advanced Highway Systems) are seen in many fields. However, there still remains many problems when we try to realize the automated driving, the goal of AHS. To overcome these problems of AHS, we have proposed HIR system, which assists drivers by providing them with integrated and restructured images. The striking point of the proposed system compared with the conventional one is that it is human, not the mechanical cars, that recognizes the situation and controls the car, and for that purpose, we just generate and show easy-to-understand images for human. The step is, integrate and restructure numerous camera images from all driving environment, such as cars and roads, and non-image information like VICS (Vehicle Information and Communication Systems) information. Then pick out the most important information according to the situation and show it in the form of 'image.' This paper proposes a bird's-eye view system as an example of HIR. We describe the algorithm and hardware to create a bird's-eye view in real-time. In the experiment, we show that the bird's-eye view is useful as a driver-assisting image under the situation of right turn at the intersection.

Evaluating Model for E-learning Modules According to Selected Criteria: An Object Oriented Approach  

Directory of Open Access Journals (Sweden)

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.

Coping Experiences: A Pathway towards Different Coping Orientations Four and Twelve Months after Myocardial Infarction-A Grounded Theory Approach.  

Science.gov (United States)

Background. Patients recovering from a myocardial infarction (MI) are faced with a number of serious challenges. Aim. To create a substantive theory on myocardial infarction patients' coping as a continuum. Methods. Grounded theory method was used. Data were collected by using individual interviews. The informants were 28 MI patients. Results. The core category "coping experiences-a pathway towards different coping orientations" includes 2 main categories: "positive and negative coping experiences" (4 months after MI) and "different coping orientations" (12 months after MI). Conclusion. Coping with a myocardial infarction is a long-term dynamic process of dealing with varied emotions and adjustment needs. Coping is threatened, if the patient denies the seriousness of the situation, suffers from depression and emotional exhaustion, or if there are serious problems in the interaction with family members. This study stresses the importance of recognizing the patient's depressive state of mind and the psychological aspects which affect family dynamics. A more family-centered approach involving a posthospital counseling intervention is recommended. Relevance to Clinical Practice. The results of this study can be used in nursing care practice when organizing support interventions for myocardial infarction patients. PMID:23304483

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

International Nuclear Information System (INIS)

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

An Integrated Approach for Extraction of Objects from XML and Transformation to Heterogeneous Object Oriented Databases  

CERN Document Server

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...

Business process learning on the job: A design science oriented approach and its empirical evaluation  

Directory of Open Access Journals (Sweden)

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

Object Oriented Approach for Integration of Heterogeneous Databases in a Multidatabase System and Local Schemas Modifications Propagation  

CERN Document Server

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

A collaborative approach to control hypertension in diabetes: outcomes of a pilot intervention.  

Science.gov (United States)

We sought to develop and pilot an intervention to improve blood pressure (BP) and other intermediate outcomes (hemoglobin A1c, low-density lipoprotein cholesterol) of diabetes in a low-income, ethnically diverse population. English- or Spanish-speaking primary care patients with BP ? 140/90 on 2 visits in the past 12 months and any level of A1c were randomized to usual care (n = 24) or intervention (n = 31). Home health nurses assessed self-management and medication adherence, and they performed health behavior counseling. Participants transmitted daily BP and glucose results using simple home telemetry units to the nurse coordinator; these results were then aggregated and transmitted weekly to primary care providers to facilitate intensified treatment. After controlling for baseline levels, a significantly larger proportion of the intervention group was at goal for BP (adjusted OR = 9.3, P = .006) and A1c (AOR = 4.3, P = .049), but not for low-density lipoprotein cholesterol (AOR = 1.1, P =.86). Clinicians made more BP medication changes in the intervention group compared to the control group (8.3 vs 3.8, approaching significance at P = .06). Self-reported medication adherence and self-care behaviors were not significantly improved. We successfully developed a telephone- and email-based collaboration between home health nurses and primary care clinicians to address poorly controlled hypertension in an ethnically diverse population. The intervention, combining enhanced feedback to patients and their primary care providers and individualized behavior change support by home health nurses, is effective for improving BP and glucose in this setting.

Modelling tritium and carbon 14 in the environment: a biomass oriented approach  

International Nuclear Information System (INIS)

There are many existing models describing the behaviour of carbon 14 and tritium in the environment. There are all quite difficult to handle and data consuming because they are based on the precise description of the different and complex mechanisms of the carbon and hydrogen cycles. A simplified model of transfer in the environment of tritium and carbon 14 is presented. It is based on the following assumptions: (a) the modelled radionuclides have an homogeneous repartition inside the biological compartments considered; (b) transfer flows of such radionuclides are proportional to the biomass changes in all the biological compartments; (c) time evolution of radionuclides isotopic equilibrium is discrete. Such a dynamic approach is based on the use of growth models of biological systems (plants, animals, etc..). From the proposed conceptual model, 2 mathematical models are proposed: a one pool model (organic carbon for carbon 14) and a two-pool model (organic tritium and tritiated water for tritium).

Integration of environmental approaches to strategy of production enterprises - environmentally oriented quality of production  

Directory of Open Access Journals (Sweden)

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.

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

Science.gov (United States)

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.

Modelling nitrogen transport and turnover at the hillslope scale - a process oriented approach  

Science.gov (United States)

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.

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

Science.gov (United States)

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

Decision support system for transport demand management: Object oriented approach using kappa pc 2.4 expert system shell  

Directory of Open Access Journals (Sweden)

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.

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

Digital Repository Infrastructure Vision for European Research (DRIVER)

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

Outcome Measures of a Family-Based Education Approach with Mexican Immigrants in the Yakima Valley  

Directory of Open Access Journals (Sweden)

Full Text Available With the continued incidence of obesity and health related issues in the United States and especially in the Hispanic population, it is important to provide useful healthy lifestyle education to this population. One of the barriers to providing this information is the lack of culture sensitivity in the content and presentation of current programs. In this pilot study, pre and post tests were used to measure the effectiveness of Salsa, Sabor, y Salud, a culturally sensitive program designed for Latinos. Outcome measures included dietary changes, weight, body mass index, waist circumference, blood pressure, heart rate, reported physical activity, and healthy lifestyle score. Diet was evaluated by 24-hour diet recall for both adults and children. Difference in outcome measures was assessed using a dependent t test. Significant decreases in weight, waist circumference, diastolic blood pressure, kilocalories, and grams of carbohydrates were observed. Adults reported an increase in total minutes of physical activity and the importance of living a healthy lifestyle. This culturally sensitive education program, Salsa, Sabor, y Salud, has a positive effect on health related outcome measures.

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

Science.gov (United States)

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

An integrated approach to defining genetic and environmental determinants for major clinical outcomes involving vitamin d.  

Science.gov (United States)

There is substantial genetic and epidemiological evidence implicating vitamin D in the pathogenesis of many common diseases. A number of studies have sought to define an association for disease with sequence variation in the VDR gene, encoding the ligand-activated nuclear hormone receptor for vitamin D. The results of such studies have been difficult to replicate and are likely to need to account for specific environmental exposures. Here, we review recent work that has begun to study the interactions between VDR gene polymorphisms, vitamin D blood levels, and complex disease susceptibility, notably in the context of major clinical outcomes. We highlight the challenges moving forward in this area and its importance for effective clinical translation of current research. PMID:24557774

Ovarian serous adenocarcinoma identified during IVF: diagnostic approach, surgical management, and reproductive outcome  

Directory of Open Access Journals (Sweden)

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.

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

Directory of Open Access Journals (Sweden)

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

Thirty-Day Outcome of Transcatheter Aortic Valve Implantation With the Edwards SAPIEN XT Prosthesis via the Transiliofemoral Approach.  

Science.gov (United States)

Background:?Few data exist on the results of transcatheter aortic valve implantation (TAVI) via the transfemoral approach in small slightly built Japanese patients with severe aortic stenosis who are ineligible or at high-risk for conventional surgical aortic valve replacement (SAVR). Therefore, the purpose was to investigate the early outcomes of TAVI using the transiliofemoral approach in Japan. Methods and Results:?Between June 2010 and June 2013, 21 consecutive patients (mean age, 81.0 years; 81.0% female) underwent TAVI with Edwards SAPIEN XT valves using the transiliofemoral approach. The mean body surface area was 1.44±0.15m(2). The device success rate was 90.5%. Although 2 patients did not meet the echocardiographic criteria for device success, no failure to deliver and deploy a valve occurred. The mean effective aortic valve area increased from 0.54±0.12cm(2) at baseline to 1.46±0.29cm(2) after the procedure (PTAVI with the Edwards-SAPIEN XT valve via the transiliofemoral approach at Kurashiki Central Hospital is satisfactory for patients who are ineligible or at high risk for SAVR.??(Circ J?2014; 78: 1357-1363).

Multiple-Quantum NMR Spectra of Partially Oriented Indene: A New Approach to Estimating Order in a Nematic Phase  

Science.gov (United States)

Multiple-quantum proton NMR spectra of the 8-spin system of indene partially oriented in a nematic mesophase were acquired using a magnetic field gradient (MFG) method. Six-, seven- and eight-quantum spectra were solved to yield all intramolecular dipolar couplings ( Dij) which were used to determine the molecular shape. The spectral widths of multiple-quantum spectra are dependent on molecular orientation and geometry and a novel method was developed to estimate the Saupe order parameters from the observed spectral widths of the high-order multiple-quantum spectra.

A biology-driven approach identifies the hypoxia gene signature as a predictor of the outcome of neuroblastoma patients  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Hypoxia is a condition of low oxygen tension occurring in the tumor microenvironment and it is related to poor prognosis in human cancer. To examine the relationship between hypoxia and neuroblastoma, we generated and tested an in vitro derived hypoxia gene signature for its ability to predict patients' outcome. Results We obtained the gene expression profile of 11 hypoxic neuroblastoma cell lines and we derived a robust 62 probesets signature (NB-hypo taking advantage of the strong discriminating power of the l1-l2 feature selection technique combined with the analysis of differential gene expression. We profiled gene expression of the tumors of 88 neuroblastoma patients and divided them according to the NB-hypo expression values by K-means clustering. The NB-hypo successfully stratifies the neuroblastoma patients into good and poor prognosis groups. Multivariate Cox analysis revealed that the NB-hypo is a significant independent predictor after controlling for commonly used risk factors including the amplification of MYCN oncogene. NB-hypo increases the resolution of the MYCN stratification by dividing patients with MYCN not amplified tumors in good and poor outcome suggesting that hypoxia is associated with the aggressiveness of neuroblastoma tumor independently from MYCN amplification. Conclusions Our results demonstrate that the NB-hypo is a novel and independent prognostic factor for neuroblastoma and support the view that hypoxia is negatively correlated with tumors' outcome. We show the power of the biology-driven approach in defining hypoxia as a critical molecular program in neuroblastoma and the potential for improvement in the current criteria for risk stratification.

Outcomes of Interventions Via a Transradial Approach for Dysfunctional Brescia-Cimino Fistulas  

International Nuclear Information System (INIS)

The transradial artery approach to angioplasty has rarely been reported as a method for treating dysfunctional Brescia-Cimino fistulas. This study evaluated the feasibility, safety, and 1-year efficacy of this method for treating dysfunctional Brescia-Cimino fistulas. We retrospectively evaluated 154 consecutive procedures in 131 patients (age, 58.3 ± 11.6 years; male, 48.1%) who underwent the transradial approach in dysfunctional Brescia-Cimino fistulas in the 1-year period after the procedure. The operator determined the use of a regular or a cutting balloon (two cases) in combination with urokinase injection (one case) or catheter thromboaspiration. Radial artery puncture was successful in all cases. Fifty-two cases (33.8%) had totally occluded fibrotic lesions. The overall anatomic success rate and clinical success rate were 61% (94/154) and 81.1% (125/154), respectively. In cases with a totally occluded fibrotic lesion, the clinical success rate was 46%. Successful intervention was associated with a significant reduction in the radial arterial systolic and diastolic pressures. There were no complications of symptomatic arterial embolization or pulmonary embolism, and one complication of venous rupture was successfully treated by compression. The primary patency rates based on intention-to-treat were 75.3% at 30 days and 39.0% at 1 year after the procedure. Excluding the cases with a totally occluded lesion, the clinical success rate was 99% (101/102) and the primary patency rates were 84.3% (86/102) and 52.0% (53/102) at 3 months and 1 year after the procedure, respectively. In conclusion, the transradial approach is a feasible, safe, and effective alternative for catheter intervention for dysfunctional Brescia-Cimino fistulas. Its success rate in cases with a totally occluded fibrotic lesion is unsatisfactory.

Surgical outcomes using a medial-to-lateral endonasal endoscopic approach to pituitary adenomas invading the cavernous sinus.  

Science.gov (United States)

Object This study details the extent of resection and complications associated with endonasal endoscopic surgery for pituitary tumors invading the cavernous sinus (CS) using a moderately aggressive approach to maximize extent of resection through the medial CS wall while minimizing the risk of cranial neuropathy and blood loss. Tumor in the medial CS was aggressively pursued while tumor in the lateral CS was debulked in preparation for radiosurgery. Methods A prospective surgical database of consecutive endonasal pituitary surgeries with verified CS invasion on intraoperative visual inspection was reviewed. The extent of resection as a whole and within the CS was assessed by an independent neuroradiologist using pre- and postoperative Knosp-Steiner (KS) categorization and volumetrics of the respective MR images. The extent of resection and clinical outcomes were compared for medial (KS 1-2) and lateral (KS 3-4) lesions. Results Thirty-six consecutive patients with pituitary adenomas involving the CS who had surgery via an endonasal endoscopic approach were identified. The extent of resection was 84.6% for KS 1-2 and 66.6% for KS 3-4 (p = 0.04). The rate of gross-total resection was 53.8% for KS 1-2 and 8.7% for KS 3-4 (p = 0.0006). Six patients (16.7%) had preoperative cranial neuropathies, and all 6 had subjective improvement after surgery. Surgical complications included 2 transient postoperative cranial neuropathies (5.6%), 1 postoperative CSF leak (2.8%), 1 reoperation for mucocele (2.8%), and 1 infection (2.8%). Conclusions The endoscopic endonasal "medial-to-lateral" approach permits safe debulking of tumors in the medial and lateral CS. Although rates of gross-total resection are moderate, particularly in the lateral CS, the risk of permanent cranial neuropathy is extremely low and there is a high chance of improvement of preexisting deficits. This approach can also facilitate targeting for postoperative radiosurgery. PMID:24527820

A new approach for the automatic evaluation of the solidification structure in steel using orientational entropy filtering.  

Science.gov (United States)

We present a new method for the automatic evaluation of the dendritic solidification structure in metallurgical micrographs of solidified steel. The evaluation of the microstructural parameters such as the primary dendrite arm spacing and the primary grain size are of high importance due to their direct relationship with the internal quality and mechanical properties of the cast product. Given the repeated geometric features in the micrographs and the regular pattern in colour intensity, we applied a filter mask to determine the local entropies within the masks in order to detect the centre coordinates of each individual dendrite. The orientation of the dendrites was determined by rotating the filter mask over each pixel to find the orientation which corresponds to the lowest entropy value. The segmentation of the microstructure was then performed via Delaunay tessellation and subsequent transformation of the triangular mesh into a rectangular grid, enabling the determination of the desired microstructural parameters.

Survival and Failure Outcomes in Primary Thyroid Lymphomas: A Single Centre Experience of Combined Modality Approach  

Science.gov (United States)

Primary thyroid lymphoma (PTL) is a rare malignancy and represents 2%–5% of all thyroid malignancies and 1%–2.5% of all malignant lymphomas. We present our institute's experience in combined modality management of 16 successive patients of PTL treated from 2005 to 2010. The median age of the patients was 56.0 years. Five patients were males, and 11 patients were females. An enlarging thyroid mass was the most common presenting symptom. 14 patients had diffuse large B-cell lymphoma, and 2 patients had follicular lymphoma. The most common stage of presentation was stage II comprising 6 (37.5%) patients. All patients received CCT, and only 12 patients received involved field RT with a median dose of 36.0 Gy. 10 patients (62.5%) had CR, and 6 patients (27.5%) had PR. Eight patients had disease progression in subsequent followup and this included the initial 6 patients with PR. The 5-year DFS was 40.0%, and median DFS was 47 months. The 5-year OS was 41.0%, and median OS was 51 months. Most common presentation in our series was locally advanced tumors. Most of these patients require combined modality management. Risk-adapted and multimodality approach is the need of the hour to achieve good control rates while minimizing treatment related toxicity.

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.

Aspect Oriented Requirements Engineering  

Directory of Open Access Journals (Sweden)

Full Text Available Requirements engineering techniques that explicitly recognize the importance of clearly identifying and treating crosscutting concerns are called Aspect-oriented Requirements Engineering Approaches (AORE approaches. The emergence of aspect-oriented programming languages has raised the explicit need to identify crosscutting concerns already during the analysis phase. Besides this observation, the modular representation of crosscutting requirements is a first step to ensure traceability of crosscutting concerns through all other artifacts of the software lifecycle (architecture, design and implementation.Aspect-oriented requirements engineering approaches improve existing requirements engineering approaches through an explicit representation (and modularization of concerns that were otherwise spread throughout other requirements artifacts (such as use cases, goal models, viewpoints, etc..AORE approaches adopt the principle of separation of concerns at the analysis phase (the early separation of concerns. In other words, AORE approaches provide a representation of crosscutting concerns in requirements artifacts.

How a diversity-oriented approach has inspired a new hypothesis for the gabosine biosynthetic pathway. A new synthesis of (+)-gabosine C.  

Science.gov (United States)

A new synthesis of (+)-gabosine C has been accomplished as part of a general diversity-oriented approach that also delivered the previously unknown (-)-4-epi-gabosine C. The identification of the unexpected intermediate (+)-8, together with the isolation of ketones 9 and 10 in previous investigations, prompted us to formulate a new hypothesis for the biosynthesis of gabosines, based on a keto-enol equilibrium cascade pathway starting from 2-epi-5-epi-valiolone, along which the necessary precursors for all the different types of gabosines are generated.

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

Energy Technology Data Exchange (ETDEWEB)

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.

Measuring health outcomes of a multidisciplinary care approach in individuals with chronic environmental conditions using an abbreviated symptoms questionnaire  

Directory of Open Access Journals (Sweden)

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

Risk factors of post-operative recurrence and adequate surgical approach to improve long-term outcomes of hepatocellular carcinoma  

Science.gov (United States)

Introduction A high recurrence rate of hepatocellular carcinoma (HCC) remains a significant concern. The risk factors for recurrence were analysed and the optimal surgical approaches were investigated. Methods The subjects comprised 280 consecutive patients with primary solitary HCC measuring ?5 cm in diameter, who underwent curative resections. Multivariate analysis was conducted to identify the risk factors for post-operative recurrence, and the clinical significance of an anatomic resection was evaluated. Results Multivariate analysis identified HCV infection, a des-gamma-carboxyprothrombin level >100 mAU/ml, underlying cirrhosis, the presence of microvascular invasion, the presence of micrometastases and non-anatomic resection as being significant risk factors for post-operative recurrence. The 5-year recurrence rate was 56.7% in the anatomic resection (AR) group and 74.7% in the non-AR group. The 5-year survival rate was 82.2% in the AR group and 71.9% in the non-AR group. Local recurrence within the same segment was observed in 25% of the patients of the non-AR group. The prognostic superiority of AR was confirmed only in patients with histopathological evidence of microvascular invasion and/or micrometastases, and in patients having a solitary HCC measuring 2 to 5 cm in diameter. Conclusions Anatomic resection may decrease local recurrence and improve the surgical outcomes in solitary HCC measuring 2 to 5 cm in diameter.

Supporting Browsing of Blogs via Text Clustering and Concept Analysis Techniques: A Task-Oriented Evaluation Approach  

Directory of Open Access Journals (Sweden)

Full Text Available Blogs are a good online tool that encourages information exchange and knowledge sharing. However, blog users often face two challenges. First, blog contents are often categorized vaguely or inadequately by authors. Second, many popular blogs sort content by date. Consequently, when a blog user does not possess the right keywords forinformation retrieval, he or she must take time to browse the contents by chronological order until the relevant content is identified. This study addressed the problems by using the hierarchical agglomerative clustering and formal concept analysis methods to re-classify blog contents. To evaluate the effectiveness of the proposed automated text clustering solution, we further conducted user task-oriented evaluation. The results showed that the technique can help authors (bloggers definenew categories and refine existing categories. In addition, the concept hierarchy applied in each category helped the blog users to quickly discover the needed information.

A Rapid, Object-Oriented Approach to Regional-Scale Wetland Mapping in the Congo River Basin  

Science.gov (United States)

Wetlands continue to be lost and degraded faster than any other ecosystem despite their importance to hydrology, biogeochemistry and biodiversity. A rapid, regional-scale method for creating wetland inventories is urgently needed to improve hydrological and biogeochemical models as well as conservation efforts, especially for threatened areas that lack baseline information. The wetlands of the Congo River Basin are among the world's largest but are understudied and face imminent development pressures. The potential of combining radar imagery (JERS-1/SAR GRFM) with elevation data (SRTM-derived DEM and derivatives) using object-oriented analysis to rapidly map Congo wetlands is investigated in this study. Findings are comparable to previous, sub-regional wetland analyses of the basin. An accuracy assessment will be presented that compares the results to a partial, reclassified reference map of the basin (FAO Africover). The method shows promise for deriving basic wetland inventories and monitoring programs for the Congo River Basin and other large tropical riverine environments.

An agent-based and semantic service oriented approach for service discovery in Network Centric Warfare (NCW  

Directory of Open Access Journals (Sweden)

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.

Competitiveness through strategic orientation  

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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.

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.

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

Science.gov (United States)

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.

Comparison of the Outcome in Bilateral Staged Total Hip Arthroplasty: Modified Two-Incision Minimally Invasive Technique versus the Conventional Posterolateral Approach  

Science.gov (United States)

This retrospective study was undertaken to compare the outcomes of staged bilateral total hip arthroplasty (THA) by the conventional approach with those of two-incision minimally invasive (MIS-2) THA in terms of clinical and radiological results, complications, and patient preferences. Twenty-two patients aged 30 to 80 years underwent staged bilateral THA. The conventional posterolateral approach was used on the first hips treated and a modified MIS-2 approach on the second hips. The mean time between the first and second procedures was 73.8 months, and the patients were followed up for at least 12 months after both procedures. At the last follow-up visits, THA via the MIS-2 approach was found to provide significantly earlier partial-weight-bearing ambulation, better postoperative Harris hip scores, and better ability to sit cross-legged and was found to be more preferred by patients than conventional THA. There were no significant differences in the complication rates for the two approaches. The present results show that MIS-2 THA is as safe as the conventional posterolateral approach in experienced hands and presents no additional complication risks.

Long-term outcome of Ludloff’s medial approach for open reduction of developmental dislocation of the hip in relation to the age at operation  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We reviewed long-term outcomes after open reduction by the medial approach for developmental dislocation of the hip (DDH). Forty-five hips in 43 patients with more than ten years of follow-up were assessed clinically and radiologically. The mean age at surgery was 14.0 (range 6–31) months, and the follow-up period ranged from ten to 28 years (mean 16.4 years). We compared the good (18 hips) and poor groups (27 hips) as classified by the Severin classification. The mean age at surgery was ...

OBJECT ORIENTED DESIGN HEURISTICS  

Directory of Open Access Journals (Sweden)

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

The mediation proportion: a structural equation approach for estimating the proportion of exposure effect on outcome explained by an intermediate variable.  

Science.gov (United States)

It is often of interest to assess how much of the effect of an exposure on a response is mediated through an intermediate variable. However, systematic approaches are lacking, other than assessment of a surrogate marker for the endpoint of a clinical trial. We review a measure of "proportion explained" in the context of observational epidemiologic studies. The measure has been much debated; we show how several of the drawbacks are alleviated when exposures, mediators, and responses are continuous and are embedded in a structural equation framework. These conditions also allow for consideration of several intermediate variables. Binary or categorical variables can be included directly through threshold models. We call this measure the mediation proportion, that is, the part of an exposure effect on outcome explained by a third, intermediate variable. Two examples illustrate the approach. The first example is a randomized clinical trial of the effects of interferon-alpha on visual acuity in patients with age-related macular degeneration. In this example, the exposure, mediator and response are all binary. The second example is a common problem in social epidemiology-to find the proportion of a social class effect on a health outcome that is mediated by psychologic variables. Both the mediator and the response are composed of several ordered categorical variables, with confounders present. Finally, we extend the example to more than one mediator. PMID:15613954

Dose prescription in carbon ion radiotherapy: a planning study to compare NIRS and LEM approaches with a clinically-oriented strategy  

Science.gov (United States)

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.

Outcome of a Standardized Approach to Childhood Urinary Symptoms-Long-Term Follow-Up of 720 Patients  

DEFF Research Database (Denmark)

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

Evaluating hospitals' provision of community benefit: an argument for an outcome-based approach to nonprofit hospital tax exemption.  

Science.gov (United States)

Nonprofit hospitals are exempt from federal income taxation if they pass organizational and operational tests, including satisfying the community-benefit standard. Policymakers, however, have questioned the adequacy of the community benefits that nonprofit hospitals provide in exchange for these exemptions. The Internal Revenue Service recently responded to these concerns by redesigning its tax forms for nonprofit hospitals. The new Form 990 Schedule H requires nonprofit hospitals to provide additional information about their community-benefit activities. This new reporting requirement, however, places an undue focus on input-based community-benefit indicators, in particular expenditures. We argue that expanding the current input-based reporting requirement to include not only monetary inputs but also population health outcomes would achieve greater benefit for society. PMID:23409909

Learning Approach for Hand Eye Coordination and the Kinesthetic Outcomes of Learning to Throw-Catch a Ball  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this study was to investigate the effects caused by the methods of teaching and eye-hand coordination to kinesthetic outcomes of throwing and catching a ball. The population of this study was 149 third grade elementary school students in a village in East Jakarta. A sample of 80 students was chosen using random cluster sampling. Data was analyzed using analysis of variance (ANOVA and the significance level is set at 0.05. The results showed that the kinesthetic of ball’s throw-catch by students who were taught with play teaching method is higher than the students who were taught with the guided teaching methods. There is an interaction between teaching methods, gender and hand eye coordination towards the kinesthetic outcomes of throwing and catching a ball. The kinesthetic result of ball’s throw-catch for male students who were taught with play teaching methods is higher than the male students who were taught with guided hand-eye-coordination teaching method. The kinesthetic result of ball’s throw-catch for female students who were taught with play teaching methods is higher than the female students who were taught with guided hand-eye-coordination teaching method. The kinesthetic result of ball’s throw-catch for male students with low hand-eye coordination taught with guided teaching method is higher than those who were taught with the play teaching method. The kinesthetic result of ball’s throw-catch for female students with low hand-eye coordination taught with the guided teaching method is higher than those taught with the play teaching method.

Assessing the children's views on foods and consumption of selected food groups: outcome from focus group approach.  

Science.gov (United States)

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.

Consolation as a unique outcome within a pastoral-narrative approach to grief Troos as unieke uitkoms in ‘n pastoraal-narratiewe benadering tot rousmart  

Directory of Open Access Journals (Sweden)

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

Exposure to Adolescent Community Reinforcement Approach treatment procedures as a mediator of the relationship between adolescent substance abuse treatment retention and outcome.  

Science.gov (United States)

Data from 399 adolescents, who participated in one of four randomly controlled trials of the Adolescent Community Reinforcement Approach (A-CRA) intervention, were used to examine the extent to which exposure to A-CRA procedures mediated the relationship between treatment retention and outcomes. Although zero-order correlations indicated that retention in treatment was a significant predictor of alcohol and other drug (AOD) use (r = -0.18, p root mean square error of approximation = .00; comparative fit index = 1.00) and explained 29% and 43% of the variance in adolescents' posttreatment AOD use and AOD-related problems, respectively. In addition, Chi-Squared Automatic Interaction Detection analysis was used to derive a target level of A-CRA exposure, which was found to be significantly related to being in recovery at follow-up. The current findings are useful, as little research to date has identified significant mediators of the relationship between retention and treatment outcomes or identified target thresholds of treatment exposure.

Improving performance and outcome (mortality after implementation of a change-bundle approach for management of septic patients  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: Despite the existence of evidence-based guidelines forthe management of patients with severe sepsis and septic shock,there is much variation among individual treatments. Methods: Abefore-after study with prospective data collection was performedat the emergency department and intensive care unit of a 485-bed,private, tertiary, general hospital. A total of 160 patients were enrolled(94 in a “pre-protocol phase” and 66 in a “post-protocol phase”. Aresuscitation bundle for the first six hours and a management bundlefor 24 hours were used. Additional quality indicators were alsoproposed and evaluated. The outcomes analyzed included hospitalmortality, hospital and intensive care unit length of stay, compliancewith bundles and performance related to quality indicators. Results:From the “pre-protocol” to “post-protocol” phase, the diagnosismoved from the intensive care unit (52.0 to 18.2% to the emergencydepartment (26.6 to 40.9% and to the wards (17.0 to 36.4%.Number of blood cultures prior to antibiotics, administration ofactivated drotrecogin alfa, use of corticosteroids and compliancewith six-hour and 24-hour sepsis bundles were significantly higherafter protocol implementation. Patients in the “post-protocol” grouphad a statistically lower risk of in-hospital mortality (56.4 versus36.4%, p = 0.01. The greatest decrease in mortality rate occurredamong the most critically ill patients (67.7 to 40.7%, p = 0.004.Conclusions: Adopting an institutional protocol focused on behavioralchanges and using quality improvement tools led to reduced hospitalmortality and generated changes in healthcare team practice. Thisresult adds to the growing evidence that optimized process-of-careby implementing managed protocols for sepsis patients can reducemortality. Therefore, similar strategies should be routinely employed.

Statistical Approaches for Analyzing a Continuous Outcome in Experimental Studies / Métodos Estadísticos para Análizar un Resultado Continuo en Estudios Experimentales  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: English Abstract in spanish En estudios experimentales, la variable resultado se mide en el momento inicial y luego en diversas ocasiones. De este modo, se habla de mediciones de "línea de base" y seguimiento respectivamente. Lo interesante de esta materia es poder determinar si una vez aplicada una intervención, existen difer [...] encias significativas entre el grupo al que se asignó un tratamiento de prueba y el grupo de comparación. En este manuscrito se exponen algunas de las estrategias utilizadas para tal propósito; las que incluyen un proceso de simulación mediante datos obtenidos a partir de un estudio experimental. Tres estrategias paramétricas y dos no paramétricas se evalúan teniendo en cuenta sólo una medida de seguimiento. La medida de referencia se incorpora en el contexto de estas estrategias.

In addition, one wants to estimate the difference effect between groups. This paper studies some of the strategies, including a simulation process, that one can be used for analyzing data coming from an experimental study as above, and considers using or not using the baseline measurements. Three parametric and two non-parametric strategies are evaluated considering only one follow-up measurement. The baseline measurement is incorporated in context in these strategies.

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 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.

A comparison of three random effects approaches to analyze repeated bounded outcome scores with an application in a stroke revalidation study.  

Science.gov (United States)

Discrete bounded outcome scores (BOS), i.e. discrete measurements that are restricted on a finite interval, often occur in practice. Examples are compliance measures, quality of life measures, etc. In this paper we examine three related random effects approaches to analyze longitudinal studies with a BOS as response: (1) a linear mixed effects (LM) model applied to a logistic transformed modified BOS; (2) a model assuming that the discrete BOS is a coarsened version of a latent random variable, which after a logistic-normal transformation, satisfies an LM model; and (3) a random effects probit model. We consider also the extension whereby the variability of the BOS is allowed to depend on covariates. The methods are contrasted using a simulation study and on a longitudinal project, which documents stroke rehabilitation in four European countries using measures of motor and functional recovery.

Nursing approaches for pain diagnosis and classification of outcomes / Condutas de enfermagem no diagnóstico da dor e a classificação dos resultados  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese JUSTIFICATIVA E OBJETIVOS: O enfermeiro deve exercer seu papel no controle da dor, e tem responsabilidade na avaliação diagnóstica, na intervenção, na monitorização dos resultados e no tratamento, como membro da equipe de saúde. O objetivo deste estudo foi identificar as condutas de acadêmicos de e [...] nfermagem sobre as intervenções a partir do diagnóstico de enfermagem de dor, segundo a taxonomia II da North American Nursing Diagnosis Association e a associação dos resultados de enfermagem perante as medidas de intervenção. MÉTODOS: Estudo do tipo transversal de natureza quantitativa, utilizando como instrumento um caso clínico. A amostra estudada foi composta por 60 acadêmicos de enfermagem cursando o último período da graduação. A pesquisa deu-se em duas Instituições de Ensino Superior Públicas, ambas localizadas no estado de Pernambuco. RESULTADOS: Da amostra analisada a maior proporção dos acadêmicos (69%) não apresentou intervenções para o caso clínico. Dos 31% que apresentaram intervenções, apenas 58% apresentaram os resultados esperados, segundo a Classificação dos Resultados de Enfermagem com base nas intervenções planejadas. 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.

Outcomes of psychotherapy from the perspective of the users.  

Science.gov (United States)

Psychotherapy is widely held to be an effective means to decrease depression. It seems, however, that not everyone benefits from every kind of therapy, and the relevant outcomes vary from person to person. In this article, the pre-therapy views and post-therapy experiences of 14 users of either long-term psychodynamic psychotherapy or short-term solution-focused therapy are analyzed. The interviewees' personal views about their depression and therapy are approached with the concept of inner narrative. Three "basic stories" or orientations were found: life historical, situational and moral. These offered people different contexts from which to evaluate the outcomes of their therapy. The findings suggest that a person's expectations, hopes and values are worth taking into account to ensure positive therapy outcomes. PMID:21347980

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

Development of symptoms-oriented operating procedures  

International Nuclear Information System (INIS)

Until recently, the formal treatment of control room procedures for upset conditions in nuclear power plants has been event-oriented. This orientation was not so much a reflection of power plant operating practice as it was a reflection of design-oriented thinking - design-basis events, therefore event-oriented procedures. Event orientation is not common in other professions. In the medical profession, for example, the stabilization of vital functions through a symptoms-oriented approach has priority over diagnosis and prognosis. The American nuclear power industry has initiated programs for the development and application of a symptoms-oriented approach for handling upset conditions. Canadian programs have independently paralleled the US programs. This article describes the rationale and current applications of the Canadian programs and identifies the relevance of a generic symptoms-based emergency procedure to current operating practices

Direct relative orientation with four independent constraints  

Science.gov (United States)

Relative orientation based on the coplanarity condition is one of the most important procedures in photogrammetry and computer vision. The conventional relative orientation model has five independent parameters if interior orientation parameters are known. The model of direct relative orientation contains nine unknowns to establish the linear transformation geometry, so there must be four independent constraints among the nine unknowns. To eliminate the influence of over parameterization of the conventional direct relative orientation model, a new relative orientation model with four independent constraints is proposed in this paper. The constraints are derived from the inherent orthogonal property of the rotation matrix of the right image of a stereo pair. These constraints are completely new as compared with the known literature. The proposed approach can find the optimal solution under least squares criteria. Experimental results show that the proposed approach is superior to the conventional model of direct relative orientation, especially at low altitude and close range photogrammetric applications.

The Tinnitus Research Initiative (TRI database: A new approach for delineation of tinnitus subtypes and generation of predictors for treatment outcome  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Tinnitus, the phantom perception of sound, is a frequent disorder that causes significant morbidity and treatment is elusive. A large variety of different treatment options have been proposed and from most of them some patients benefit. However, a particular treatment that helps one patient may fail for others. This suggests that there are different forms of tinnitus which differ in their pathophysiology and their response to specific treatments. Therefore, it is a major challenge for tinnitus treatment to identify the most promising therapy for a specific patient. However, most published clinical treatment studies have enrolled only relatively small patient samples, making it difficult to identify predictors of treatment response for specific approaches. Furthermore, inter-study comparability is limited because of varying methods of tinnitus assessment and different outcome parameters. Performing clinical trials according to standardized methodology and pooling the data in a database should facilitate both clinical subtypisation of different forms of tinnitus, and identification of promising treatments for different types of tinnitus. This would be an important step towards the goal of individualized treatment of tinnitus. For these reasons, an international database of tinnitus patients, who undergo specific treatments, and are assessed during the course of this treatment with standardized instruments (e.g., psychoacoustic measures, questionnaires has been established. The primary objectives of this database are (1 collecting a standardized set of data on patient characteristics, treatments, and outcomes from tinnitus patients consulting specialized tinnitus clinics all over the world (at present 13 centers in 8 countries, (2 delineating different subtypes of tinnitus based on data that has been systematically collected and (3 identifying predictors for individual treatment response based on the clinical profile. Starting in 2008, the database currently contains data from more than 400 patients. It is expected that more centers will join the project and that the patient numbers will rapidly grow, so that this international database will further facilitate future research and contribute to the development of evidence based on individualized treatment.

Math and Calculation – A Test for Diagnosing Concepts at Pre-school Age – An Example of a Level-oriented Approach  

Directory of Open Access Journals (Sweden)

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.

A rapid, object-oriented approach to mapping and classifying wetlands at a regional scale in the central Congo River basin  

Science.gov (United States)

Tropical floodplain wetlands are important from various perspectives, including hydrology, biogeochemistry and conservation, while facing imminent threats aggravated by insufficient baseline information. Recent advances in remote sensing and image analysis can address this problem. The integration of radar imagery (L-HH) with topographic datasets (elevation, slope and waterbodies) in an object-oriented analysis was tested as a method of rapid wetland mapping in the Equateur Province, Democratic Republic of Congo. Three classification schemes at different aggregation levels were produced to test thematic detail against accuracy. The highest level classifications include upland, lake, river, flooded forest, nonflooded forest, shrub and herbaceous vegetation. The maps range from 47% accuracy for the 7-class wetland map to 78% accuracy for the 3-class floodplain map compared to a reference map (FAO Africover). The method shows promise for developing inventories and monitoring programs to support wetland management in the central Congo River basin and other tropical riverine environments.

Task-oriented rehabilitation robotics.  

Science.gov (United States)

Task-oriented training is emerging as the dominant and most effective approach to motor rehabilitation of upper extremity function after stroke. Here, the authors propose that the task-oriented training framework provides an evidence-based blueprint for the design of task-oriented robots for the rehabilitation of upper extremity function in the form of three design principles: skill acquisition of functional tasks, active participation training, and individualized adaptive training. The previous robotic systems that incorporate elements of task-oriented trainings are then reviewed. Finally, the authors critically analyze their own attempt to design and test the feasibility of a TOR robot, ADAPT (Adaptive and Automatic Presentation of Tasks), which incorporates the three design principles. Because of its task-oriented training-based design, ADAPT departs from most other current rehabilitation robotic systems: it presents realistic functional tasks in which the task goal is constantly adapted, so that the individual actively performs doable but challenging tasks without physical assistance. To maximize efficacy for a large clinical population, the authors propose that future task-oriented robots need to incorporate yet-to-be developed adaptive task presentation algorithms that emphasize acquisition of fine motor coordination skills while minimizing compensatory movements.

Optical implementation of quantum orienteering.  

Science.gov (United States)

We present results from an optical implementation of quantum orienteering, a protocol for communicating directions in space using quantum bits. We show how different types of measurements and encodings can be used to increase the communication efficiency. In particular, if Alice and Bob use two spin- particles for communication and employ joint measurements, they do better than is possible with local operations and classical communication. Furthermore, by using oppositely oriented spins, the achievable communication efficiency is further increased. Finally, we discuss the limitations of an optical approach: our results highlight the usually overlooked nonequivalence of different physical encodings of quantum bits. PMID:16712138

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

Effects of orientation on growth during recrystallization  

Energy Technology Data Exchange (ETDEWEB)

Direct and indirect methods to study effects of crystallographic orientation on growth during recrystallization are described and their potentials are discussed. Recent results obtained by these methods are summarized. Growth in heavily cold deformed polycrystalline materials are discussed with reference to new data on grain subdivision by dislocation boundaries during deformation. It is shown that in these materials, simple oriented growth relationships cannot describe faster growth of grains with specific orientations. Other possibilities are discussed. Effects of cube bands, present after hot deformation, are also analysed. Finally, a new simulation approach, which allows orientation dependent growth rates to be included, is outlined.

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

Energy Technology Data Exchange (ETDEWEB)

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.)

The Role of an Area-oriented Approach in achieving environmental policy integration in the Netherlands and its applicability in Bulgaria  

Digital Repository Infrastructure Vision for European Research (DRIVER)

An integrated approach to environmental policy and urban spatial planning has not yet been adopted by many local administrations in Europe. However, such integration is likely to provide a more streamlined planning process that incorporates environmental measures in the physical development of urban areas. In this paper, we argue that among many local governments there is already a growing wish to apply environmental policy integration (EPI) principles in spatial planning in an effort to achi...

Layer-oriented simulation tool.  

Science.gov (United States)

The Layer-Oriented Simulation Tool (LOST) is a numerical simulation code developed for analysis of the performance of multiconjugate adaptive optics modules following a layer-oriented approach. The LOST code computes the atmospheric layers in terms of phase screens and then propagates the phase delays introduced in the natural guide stars' wave fronts by using geometrical optics approximations. These wave fronts are combined in an optical or numerical way, including the effects of wave-front sensors on measurements in terms of phase noise. The LOST code is described, and two applications to layer-oriented modules are briefly presented. We have focus on the Multiconjugate adaptive optics demonstrator to be mounted upon the Very Large Telescope and on the Near-IR-Visible Adaptive Interferometer for Astronomy (NIRVANA) interferometric system to be installed on the combined focus of the Large Binocular Telescope.

An integrated strategy for modelling and simulating the transitory regimes in Nuclear Power Plants. Proactive educational and training oriented approach at the University 'Politehnica' of Bucharest  

International Nuclear Information System (INIS)

This paper is a brief presentation of the preoccupation of the thermohydraulics modelling and simulating group acting at the Power Plants Department of the Faculty of Power Engineering in Bucharest aiming at creating an integrated software library to study the NPP components in abnormal and transitory regimes. The studies accomplished developed mathematical models which can be solved by using advanced codes (ACSR, MMS, MATLAB) and can be integrated in an evolving strategy for simulation. The basic elements of this strategy are: modular modelling, anticipatory approach of the evolution of the analysed systems and adaptive dynamic control. The global goal of developed simulations is an efficient identification and control of the transitory regimes having an impact on the safety performances of the plant.

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)

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.

Religious orientations and prejudice  

Directory of Open Access Journals (Sweden)

Full Text Available This study investigates the relationship between religious orientation and prejudice. This relationship is not much clear but earlier studies suggested that there has been a negative relationship between intrinsic religious orientation and prejudice towards out-groups and a positive relationship between extrinsic religious orientation and prejudice towards out-groups. Sample group is composed of university students. They were asked to complete The Religious Orientation Scale–ROS, Prejudice Scale (California F Scale, Form 40-45 and also a Personal Information Form. According to the findings there is a significant relationship between sex and department that the students are in while a similar relationship is observed between the department and intrinsic religious orientation. In addition, a relationship between intrinsic religious orientation and extrinsic religious orientation is significant. Furthermore Divinity Faculty students are not differentiated from the others in respect to extrinsic religious orientation while they have much higher scores than the others as regards to intrinsic religious orientation. Main effects of sex variable and the interaction effects of department and sex are not significant on religious orientations in statistical terms. Intrinsic religious orientation has a positive effect in predicting strict conformity to rules as sub-dimension of prejudice while it has a negative effect in predicting the disbelief to human agency. On the other hand, extrinsic religious orientation is found to be as a positive predictor of strict conformity to rules and disbelief to human agency. The variables of sex and department contributed to predict only disbelief to human agency.

Spindle orientation in mammalian cerebral cortical development.  

Science.gov (United States)

In any mitotic cell, the orientation of the mitotic spindle determines the orientation of the cleavage plane and therefore the position of the two daughter cells. When combined with polarization of cellular components, spindle orientation is also a well-conserved means of generating daughter cells with asymmetric cell fates, such as progenitors and differentiated cell types. In the mammalian neocortex, the precise planar spindle orientation observed early during development is vital for symmetric proliferative divisions. During later stages, spindles can be oblique or even vertical but the role of this reorientation is somewhat less clear as asymmetric cell fates can arise independently of spindle orientation during this stage. Although decades of work have identified many key conserved regulators of spindle positioning, its precise role in cell fate determination in the mammalian neocortex has been enigmatic. Recent work focused on mInsc and LGN has now revealed an important role for spindle orientation in determination of specific asymmetric cell fates, namely intermediate progenitors and a new progenitor population, termed outer radial glia. In this way, spindle orientation helps determine the neurogenic outcome of asymmetric progenitor divisions, thereby influencing neuron output and cerebral cortical expansion. PMID:22554882

A systematic approach to customer-oriented car tire development with shorter development times; Ganzheitliche Methode zur kundenorientierten Pkw-Reifenentwicklung bei verkuerzter Entwicklungszeit  

Energy Technology Data Exchange (ETDEWEB)

There is no alternative to pneumatic tires in the foreseeable future, although the tire industry is working on new developments. The main challenge in tire development is to find a systematic approach which will then result in shorter development times. The available techniques of simultaneous engineering, quality function deployment and failure mode and effect analysis should be combined with a cyclic development process in order to double the added value in the development process chain and reduce the development time by half. (orig./AKF). 44 figs., 28 tabs. [Deutsch] In absehbarer Zeit gibt es keine Alternative zum Luftreifen, und der Reifen bestimmt weiterhin die ausnutzbare Kraftschlussgrenze am Fahrzeug. In der Reifenentwicklung wird die Verkuerzung der Entwicklungszeit zum zentralen Problem der Kundenorientierung und somit der Kundenakzeptanz. Die Herausforderung an die Reifenentwicklung der Zukunft liegt nun darin, ganzheitlich zu denken und systemisch zu entwickeln. Erst aus diesem ganzheitlichen Ansatz folgt die verkuerzte Entwicklungszeit. - Die Verkuerzung der Entwicklungszeit ergibt sich durch konsequente Anwendung von Simultaneous Engineering, Quality Function Deployment (QFD) und Failure Mode and Effect Analysis (FMEA), gekoppelt mit einer Zyklisierung des Entwicklungsprozesses. Die sich dadurch ergebende Verdopplung der Wertschoepfung in der Entwicklungsprozesskette fuehrt zu einer Halbierung der Entwicklungszeit. (orig./AKF)

[Space and spatial orientation].  

Science.gov (United States)

Space and spatial orientation has been a subject of interest of researchers for many years. Spatial orientation can be divided into cued navigation and place navigation. The latter requires more complex neuronal computations and is considered to be a model of higher cognitive functions in animals. Allothetic orientation is based on determining the location of the subject with respect to orientating cues and gradients in its surrounding. Idiothetic orientation involves integrating the information generated during active and passive self-motion in order to obtain the actual position of the subject with respect to the starting point. This article reviews the historical evolution of spatial concepts, the types of orientation, and their neuronal implementation. Description of the most widely used methods of studying mechanisms of spatial orientation is also included. PMID:12693187

Orientalism and India  

Directory of Open Access Journals (Sweden)

Full Text Available In this article Orientalism, a special hegemonic discourse about "the Orient" by Europeans is discussed by focusing on how it is manifested in a "Western" view of India. Orientalism as a discourse about the Orient is a concept first coined by Edward Said in his book Orientalism (1978 and contains a long history of European way of relating to the Orient as a counterpart of European/Western culture. In this article Orientalist discourses about India by hegemonically Western (and particularly Anglo-Saxon sources are portrayed and the so-called Indo-Orientalist essentialism defining Indianness from the outside analyzed. Moreover, a Indo-Orientalism as an imported ideology to be used in Indian nationalist discourses to emphasize a dichotomy between India and "the West" is discussed.

Dynamics of market orientation in Croatian economy  

Directory of Open Access Journals (Sweden)

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.

Evaluación de los caminos rurales: hacia un enfoque orientado al usuario. / Assessment of rural roads. Towards a user-oriented approach.  

Directory of Open Access Journals (Sweden)

Full Text Available Este trabajo presente algunos resultados de un estudio piloto realizado para el IFRTD (Foro Internacional para el Transporte Rural y el Desarrollo, Londres sobre los temas de movilización y vialidad en la comuna de Canela, IV Región de Chile. El planteamiento es que una política coherente de vialidad rural debe tener como fundamento un entendimiento de las necesidades percibidas por las comunidades rurales y de las prioridades que expresan. Este tema se explora en el proyecto en forma preliminar utilizando metodologías cualitativas y cuantitativas para investigar las necesidades de movilización en diversas comunidades de Canela desde el punto de vista de los usuarios, operadores de transporte y autoridades locales. Se presentará un análisis de los resultados pertinentes al asunto de la vialidad, que pretende establecer de manera tentativa un perfil del usuario de los caminos rurales de la zona y las características de sus traslados más difíciles. Entre los resultados más significativos se destacan:Una percepción de los amplios efectos modernizadores que introduce la pavimentación de un camino de acceso al sector.La existencia de una correlación baja pero positiva entre la dificultad percibida por el usuario de su traslado y su evaluación del camino, que se ve relacionado con el modo de transporte que se ocupa.La conclusión principal del trabajo es que un conocimiento de los criterios propios con los cuales el usuario rural evalúa su traslado es necesario para una gestión exitosa de la vialidad rural./The author argues that a coherent policy for rural roads should be founded on the understanding of the perceived needs of rural communities and the priorities expressed.

Analyzing the Software Quality Metrics for Object Oriented Technology  

Directory of Open Access Journals (Sweden)

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.

Datafit. A new work flow oriented approach for time efficient data preparation, validation and flagging of time series data from environmental monitoring  

International Nuclear Information System (INIS)

Standardized quality assurance according to UN/WMO Global Atmosphere Watch (GAW) data quality objectives is essential for a homogeneous high level of data quality in GAW world data centers. However data processing and data preparation often times is done individually and in a non-standardized way. As an additional problem interactive data validation can be a very time consuming step on a GAW measurement station. In front of this background a new approach for a software solution with a set of time efficient and standardized methods is proposed which also can be used as a tool for future standardization of data quality assurance on GAW measurement stations. In general in order to prepare measurement data a set of methods is required. In the framework of this program the methods are ranked in two groups: first - simpler methods for managing structural changes and corrections in the time series data and second - higher developed methods for assuring a correct time structure, graphical control and flagging non representative data and for the calculation of differently or higher aggregated mean values and statistical values. By fulfilling the auxiliary condition that data treatment at first has to be finished with application of methods of group one the user is practically free in finding and selecting its way for a solution. Once the user has found an ordered set of methods and parameters which is a sufficient solution for the preparation of the actual data, the solution can be stored as a set of parameters for the individual project. This enables the user for repeating the solution at another time to another set of time series data which are produced with the same data format from the same instrument. This structure is characteristic and useful for continuous environmental monitoring which produces a high amount of time series data with a constant data format. By saving all intermediate results in a hierarchical way with a fixed naming convention, in a later time the effect of all steps of the application of methods can be traced back in the workflow history. Because the proposed methodology separates methods and its parameters, it can be a good substitution to many situations in data preparation whereas up to now normally for each little change the program source would have to be changed and compiled. This gives an essential facilitation to the whole process of data preparation of time series data in the daily monitoring. The set of methods works with ascii data files, in case each line has a time stamp with own date and time. The program works on files with arbitrary minute data or higher aggregated time data and provides precision up to the second. Dafit runs on Windows XP-Win 8. (orig.)

The role of perfectionism in cognitive behaviour therapy outcomes for clinically anxious children.  

Science.gov (United States)

The main aim of this study was to determine whether pre-treatment levels of child perfectionism impacted on anxiety treatment outcomes for school-aged children. In addition, it was investigated whether child perfectionism decreased following treatment for anxiety. Participants were sixty-seven clinically anxious children aged 6-13 years (female = 34; majority Caucasian) who were enrolled in a group-based cognitive behaviour therapy program, and their parents. They completed self-report questionnaires on anxiety and depressive symptoms and were administered a diagnostic interview to determine the type and clinician rated severity of anxiety and related disorders pre- and post-treatment and at 6-month follow-up. Self- and parent-rated perfectionism were also measured pre-treatment, while a subset of children completed perfectionism measures post-treatment as well. Self-Oriented Perfectionism, but not Socially Prescribed Perfectionism, predicted poorer self-reported treatment outcome (higher levels of anxiety symptoms) immediately following treatment and at 6-month follow-up when using a multi-informant approach. Additionally, both Self-Oriented and Socially Prescribed child perfectionism significantly reduced immediately following treatment. Despite reductions in child perfectionism following anxiety treatment, higher Self-Oriented Perfectionism may impact negatively on child anxiety treatment outcome. PMID:23850630

Oriented active shape models  

Science.gov (United States)

Active Shape Models (ASM) are widely employed for recognizing anatomic structures and for delineating them in medical images. In this paper, we present a novel strategy called Oriented Active Shape Models (OASM) in an attempt to overcome the following three major limitations of ASM: (1) poor delineation accuracy, (2) the requirement of a large number of landmarks, (3) the problem of sensitivity to search range to recognize the object boundary. OASM effectively combines the rich statistical shape information embodied in ASM with the boundary orientedness property and the globally optimal delineation capability of the live wire methodology of boundary segmentation. The latter allow live wire to effectively separate an object boundary from other non object boundaries with similar properties that come very close in the image domain. Our approach leads us to a 2-level dynamic programming method, wherein the first level corresponds to boundary recognition and the second level corresponds to boundary delineation. Our experiments in segmenting breast, liver, bones of the foot, and cervical vertebrae of the spine in MR and CT images indicate the following: (1) The accuracy of segmentation via OASM is considerably better than that of ASM. (2) The number of landmarks can be reduced by a factor of 3 in OASM over that in ASM. (3) OASM becomes largely independent of search range. All three benefits of OASM ensue mainly from the severe constraints brought in by the boundary-orientedness property of live wire and the globally optimal solution of dynamic programming.

Advances in orthopaedic outcomes research.  

Science.gov (United States)

As the field of orthopaedic surgery continues to expand in terms of indications and technologies, there has been increasing emphasis placed on validated patient-derived outcome measures in clinical orthopaedic research. As concerns mount regarding rising health care costs, declining quality, and variability in clinical practice patterns, outcome measures become important tools in assessing quality. Furthermore, outcome measures can be utilized to justify the clinical benefits of existing and new diagnostic modalities and surgical interventions. This review provides a brief overview of traditional outcomes approaches in orthopaedics followed by a discussion of the current trend toward patient-centered outcomes research and its role in the emerging field of cost-effectiveness analysis in orthopaedics.

Review on Aspect Oriented Programming  

Directory of Open Access Journals (Sweden)

Full Text Available Aspect-oriented programming (AOP has been introduced as a potential programming approach for the specification of nonfunctional component properties, such as fault-tolerance, logging and exception handling. Such properties are referred to as crosscutting concerns and represent critical issues that conventional programming approaches could not modularize effectively leading to a complex code. This paper discusses AOP concept, the necessity that led to it, how it provides better results in code quality and software development efficiency, followed by stating challenges that developers and researchers face when dealing with this approach. It has been concluded that AOP is promising and deserves more attention from developers and researchers. However, more systematic evaluation studies should be conducted to better understand its implications.

The Professional Orientation Bases for the Public Affairs Administration Major  

Directory of Open Access Journals (Sweden)

Full Text Available Public affairs administration is the major that needs to establish professional orientation most. And it is a common issue needs to be addressed urgently to scientifically define the bases of the professional orientations. Professional orientation determination primarily depends on four primary bases of major property, subject advantage, industry dependence, and employment guidance. The major property is the core basis and any party can not break this bottom line. Both the subject advantage and the industry dependence highlight the feasibility of the professional orientation. And the employment guidance is the driving force to maintain the vigorous vitality of the professional orientation. An excellent professional orientation is supposed to be the outcome based on the comprehensive consideration on these bases.
Keywords: public affairs administration; major orientation; orientation basis

Résumé: La gestion des affaires publique est une spécialité qui nécessite le plus une orientation professionnelle. Les bases de définitin scientifique de l'orientation restent des problèmes communs à résoudre. Les bases principales de la définition de l'orientation professionnelle sont les attributs professionnels, les avantages de la spécialité, les supports professionnels et le guide de l'emploi. Les attributs professionals est la base fondamentale qui ne peut pas être dépassée. Les avantages de la spécialité et les supports professionnels mettent en évidence la faisabilité de l'orientation professionnelle. Le guide de l'empoi est de maintenir la vitalité de l'orientation professionnelle. Une orientation professionnelle de bonne qualité devrait être fondée sur une prise en considération complète de tous ces éléments.

Object-Oriented Design of Graph Oriented Data Structures  

CERN Multimedia

Applied research in graph algorithms and combinatorial structures needs comprehensive and versatile software libraries. However, the design and the implementation of flexible libraries are challenging activities. Among the other problems involved in such a difficult field, a very special role is played by graph classification issues. We propose new techniques devised to help the designer and the programmer in the development activities. Such techniques are especially suited for dealing with graph classification problems and rely on an extension of the usual object-oriented paradigm. In order to support the usage of our approach, we devised an extension of the C++ programming language and implemented the corresponding pre-compiler.

Outcomes management for interventional cardiology.  

Science.gov (United States)

In the evolution of quality assessment activities in interventional cardiology, outcomes management has become the benchmark for demonstrating optimal care. The high volume of interventional cardiology procedures performed each year mandates that efficient, high-quality and cost-effective patient care be delivered to all patients with cardiovascular disease. Although the interventional cardiology procedures represent only a snap shot of the patient's management of coronary artery disease, a long-term plan for positive outcomes is required. A multidisciplinary approach to outcomes management facilitates institutions to be competitive in today's health care market. PMID:9644348

The emergence and outcomes of collective action: an institutional and ecosystem approach A emergência e os resultados da ação coletiva: uma abordagem institucional e ecossistêmica  

Directory of Open Access Journals (Sweden)

Full Text Available Participation in collective action is frequently studied through a community-based analysis, with focus on the social features of the participants and on the ecological features of the managed system. This study addresses the importance of scaling down to household level to understand different individual incentives to collaborate (or not as well as scaling up to the landscape level to evaluate the ecological outcome of the local forms of collective action. A study of a riparian community of 33 households in the Lower Amazon located between two distinct ecosystems -a privately owned upland forest and a communally owned floodplain- reveals that household-based analysis uncovers how heterogeneity within the community leads to different incentives for participation in the communal floodplain, while systemic analysis reveals that interconnection between the managed ecosystem and adjacent ecosystem influences the decisions to participate as well as the ecological outcomes of the collective actions.A participação numa ação coletiva é estudada com freqüência por meio de uma análise baseada nas comunidades e enfocada nas características sociais dos participantes e nas características ecológicas do sistema manejado. Este estudo refere-se à importância de se limitar a análise ao nível das famílias para compreender os diferentes incentivos individuais que colaboram (ou não, assim como de se ampliar a análise ao nível da esfera territorial a fim de se avaliar o resultado ecológico das formas locais de ação coletiva. Um estudo feito numa comunidade costeira de 33 famílias na Baixa Amazonia situada entre dois ecosistemas diferentes -uma mata/floresta de propriedade privada situada em terras altas e uma planície pluvial pertencente a uma comunidade- revela que a análise baseada nas famílias mostra que a heterogeneidade dentro da comunidade conduz a diferentes incentivos para participar das atividades na planície pluvial. A análise sistêmica, no entanto, mostra que a interconexão entre o ecosistema manejado e o ecosistema adjacente influi nas decisões para participar assim como nos resultados das ações coletivas.

Two-pulse orientation dynamics and high-harmonic spectroscopy of strongly-oriented molecules  

Science.gov (United States)

We present the detailed analysis of a new two-pulse orientation scheme that achieves macroscopic field-free orientation at the high particle densities required for attosecond and high-harmonic spectroscopies (Kraus et al 2013 arXiv:1311.3923). Carbon monoxide molecules are oriented by combining one-colour and delayed two-colour non-resonant femtosecond laser pulses. High-harmonic generation is used to probe the oriented wave-packet dynamics and reveals that a very high degree of orientation (Nup/Ntotal = 0.73–0.82) is achieved. We further extend this approach to orienting carbonyl sulphide molecules. We show that the present two-pulse scheme selectively enhances orientation created by the hyperpolarizability interaction whereas the ionization-depletion mechanism plays no role. We further control and optimize orientation through the delay between the one- and two-colour pump pulses. Finally, we demonstrate a complementary encoding of electronic-structure features, such as shape resonances, in the even- and odd-harmonic spectrum. The achieved progress makes two-pulse field-free orientation an attractive tool for a broad class of time-resolved measurements.

Clinical outcome of staged versus combined treatment approach of hybrid repair of thoracoabdominal aortic aneurysm with visceral vessel debranching and aortic endograft exclusion.  

Science.gov (United States)

Although visceral vessel debranching and endovascular aneurysm exclusion represents a hybrid treatment approach in patients with thoracoabdominal aortic aneurysm, the effect of timing with regard to the visceral debranching procedure and endovascular aneurysm exclusion in this treatment strategy remains unclear. In this study, the authors analyzed their recent institutional experience of visceral debranching and aneurysm stent-grafting procedures. Specifically, the authors compared the effect of staged (n = 27) versus combined (n = 31) hybrid treatment in patients with complex aortic aneurysms. This study showed a higher incidence of renal insufficiency in patients undergoing a combined hybrid repair than the staged hybrid approach. The possibility of aneurysm rupture may exist in the staged treatment approach if the duration of staged repair is prolonged. The combined hybrid treatment strategy should be performed with caution as it is associated with significantly higher complication rates than the staged hybrid treatment modality. PMID:22316552

Orientable adjustable bent sub  

Energy Technology Data Exchange (ETDEWEB)

An apparatus is provided for orienting an adjustable bent sub, as used in directional drilling of oil wells, in such a manner as to keep the bent sub as close to the drill bit as possible in accordance with proper directional drilling practice. According to the invention, an orientable adjustable bent sub has a tubular member with a first end offset to a primary axis. An adjustment sleeve, with a first end offset to a primary axis, telescopically receives the first end of the tubular member. By rotating the adjustment sleeve, the offset portion of the sleeve is adjusted in relation to the offset portion of the tubular member to produce a bend of desired magnitude. The adjustment sleeve is axially movable between an engaged and a disengaged position. In the disengaged position, the sleeve is rotatable in relation to the tubular member, permitting an adjustment to be made. An orientation sleeve telescopically receives the second end of the tubular member. By rotating the tubular member within the orientation sleeve, the bend created by the positioning of the offset portion of the adjustment sleeve in relation to the offset portion of the tubular member is oriented in a desired direction. The orientation sleeve is axially movable between an engaged and a disengaged position. In the disengaged position, the orientation sleeve is rotatable in relation to the tubular member, permitting an adjustment to be made. 4 figs.

Examining Task Oriented and Relations Oriented Team Diversity–An Analytic Review of the Banking Industry  

Directory of Open Access Journals (Sweden)

Full Text Available In today’s competitive business environment, organizations are compelled to stay on their toes at every second of their time to satisfy customers, solve economical and political problems, be cost efficient and innovative and establish a market value and name for itself. Tackling all these problems and hurdles and yet be innovative and creative cannot be managed by individuals alone. Hence, most organizations today have made use of teams, a group of people who work together towards a shared organizational goal. In teams, people from various backgrounds and expertise come together to give their opinion about a certain project so that all perspectives are kept in mind and collaborated before any decision is made. (O'Reilly et al., 1989.Since teams in organizations are made up of a diverse group of people hence there is always a possibility that they will not be able to work together. Banking Industry in Pakistan over the years has increased their focus on team work due to its challenging nature and ever changing demand for innovativeness and competitiveness. This study attempts to investigate the effects of task oriented and relation oriented diversity on team performance in the banking industry. Task oriented diversity involved factors like education, function and organizational tenure while Relation oriented diversity involved factors such as age, gender and ethnicity. The impact on team performance has been measured in terms of team members’ opinion, team leader/DOH opinion and their satisfaction levels. The study has explored how task oriented and relation oriented diversity influences the team performance with respect to three contextual factors namely: Occupational Demography (majority dominated vs balanced, Industry Setting (service industry in particular banking industry and Team Tenure (short term vs long term. The research findings revealed that the effects of relations –oriented and task oriented diversity on performance was significantly different with respect to contextual moderators and they offer new possibilities for enhancing team diversity outcomes. Therefore based on the study conclusions it is recommended that organizational practices especially HR policies and practices should consider the categorization and elaboration effects of task and relations oriented diversity in service industry. Similarly team tenure is also an important contextual moderator and diversity dynamics should be carefully understood for effective team outcomes especially in long term teams. Other industry level characteristics that have been ignored in earlier team diversity research should be examined since they offer new possibilities for enhancing team diversity outcomes.

Directory of Open Access Journals (Sweden)

Full Text Available Religious Orientations and Needs of the Ethnic Groups in the Netherlands’ Prisons: A Comparative ApproachProblem Statement Recently, in the Netherlands, which became a multicultural society, the cultural and religious structure of the people who stay in prisons changed to an important degree. This change makes it necessary to revise the institution of “spiritual care” which functions from the point of the identity of prisoners. Purpose This study intends to investigate the religious intents and needs of persons in prisons in a comparative manner in connection with the restructuring process that institution of spiritual care, which serves the prisons of the Netherlands to appropriately serve the prisoners who have various religious and cultural needs, is going through.Design/methodology/approach Ara?t?rmada, kullan??l? bir soru kâ??d? olu?turmak amac?yla önce bir pilot bir uygulama ve daha sonra da ülkesel örneklem üzerinde bir anket uygulanm??t?r. Ayr?ca manevi rehberli?in i?leyi? biçimi ve içeri?i hakk?nda daha fazla bilgi edinmek için ilgili tutukevlerindeki manevi rehberler ve bunlar?n yöneticileriyle anket yap?lm??t?r. In this research, in order to compose a useful questionnaire, first a pilot application and afterwards a survey on a national sampling has been carried out. In addition, a survey was conducted with the spiritual guides of the prisons and their managers to acquire more information about the functioning and the content of the spiritual guiding. Findings and results The findings of the research shows that the majority of the prison population for all ethnic groups belong to a certain religion and they practice it. Majority of the people in these groups either for religious, cultural, or social reasons benefit from the spiritual guidance services. Although they are satisfied with the existing spiritual guides and the services they provide, the prisoners feel the need of spiritual guides who are from the same religion as themselves. It is perceived as an important problem that the prisons do not have spiritual guides from each religious group. Considering the increase in religiousness and along with the cultural and social functions towards nonreligious groups it seems necessary to reorganize the spiritual guidance institution. Recommendation All ethnic and religious groups find the presence of spiritual care in the life of prison important and at the same time they think it is necessary to have a spiritual guide from their own religion. This is especially needed by the Muslim and Jewish prisoners. Hence, there is an immediate need to revise the policies about the spiritual guidance services.

A single center comparison of long-term outcomes of renal allografts procured laparoscopically versus historic controls procured by the open approach.  

Science.gov (United States)

We have previously reported that renal allografts procured by the laparoscopic live donor nephrectomy (lapNx) demonstrate worse early renal outcomes but noninferior 1-year renal function as compared to those procured by the standard open nephrectomy (openNx). We undertook this study to examine whether the apparent early dysfunction will impair long-term renal allograft survival. We retrospectively updated the status of the first 132 consecutive adult left lapNx recipients at our center and the preceding 99 adult openNx recipients. With a mean follow-up of 5.8+/-2.0 years in lapNx and 8.7+/-3.3 years in openNx, we found that death-censored renal allograft survival was identical on univariate and multivariate analysis. Patient survival was worse (log rank P-value=0.048) in lapNx, but this finding did not persist in multivariate analysis. Combined graft-patient survival as well as 1-year mean serum creatinine levels were similar on univariate and multivariate analyses. We conclude that, despite having suffered early renal dysfunction, the lapNx cohort of renal allograft recipients enjoys similar long-term renal allograft survival as compared to openNx.

Steiner Forest Orientation Problems  

CERN Multimedia

We consider connectivity problems with orientation constraints. Given a directed graph $D$ and a collection of ordered node pairs $P$ let $P[D]={(u,v) \\in P: D contains a uv-paths}$. In the Steiner Forest Orientation problem we are given an undirected graph $G=(V,E)$ with edge-costs and a set $P \\subseteq V \\times V$ of ordered node pairs. The goal is to find a minimum-cost subgraph $H$ of $G$ and an orientation $D$ of $H$ such that $P[D]=P$. We give a 4-approximation algorithm for this problem. In the Maximum Pairs Orientation problem we are given a graph $G$ and a multi-collection of ordered node pairs $P$ on $V$. The goal is to find an orientation $D$ of $G$ such that $|P[D]|$ is maximum. Generalizing the result of Arkin and Hassin for $|P|=2$, we will show that for a mixed graph $G$ (that may have both directed an undirected edges), one can decide in $n^{O(|P|)}$ time whether $G$ has an orientation $D$ with $P[D]=P$ (for undirected graphs this problem admits a polynomial time algorithm for any $P$, but it...
