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

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

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

Full Text Available While shedding light on the evolution of the multidisciplinary approach to orientalist studies in the 19th and early 20th centuries, this paper elaborates on the interdisciplinary approach to post-colonial studies in the second half of the 20th Century with a historical and analytical perspective. The paper is also intended to explain the transitional phase from multicultural studies to intercultural studies as well as the new methodological developments from a multidisciplinary approach to an interdisciplinary one as well as to examine the outcomes of these developments in the orientalist analyses of western academicians and the interactions between different disciplines in post-colonial studies. In response to the question as to “why has the orientalism been basically based on a multidisciplinary approach while the post-colonial studies have tended to rely on an interdisciplinary one”, this paper will make a review of the introvert factors caused by the assimilation and multifaceted nature of scientific orientalism as well as the extrovert factors caused by the influence of colonial powers on the western orientalists in studying the economic, social, cultural, political, historical and literary aspects of the oriental societies. Furthermore, the paper aims at providing an explanatory method for identifying the causes of an effort for an intercultural approach towards post-colonial studies by taking into consideration and emphasizing on field research through establishing an epistemological and methodological linkage between aesthetics, etymology, anthropology, sociology, geography and political science as well as interdisciplinary cooperation among indigenous orientalists.

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

Full Text Available The article considers the specifics of a model oriented approach to software development based on the usage of Model Driven Architecture (MDA, Model Driven Software Development (MDSD and Model Driven Development (MDD technologies. Benefits of this approach usage in the software development industry are described. The main emphasis is put on the system design, automated code generation for large systems, verification, proof of system properties and reduction of bug density. Drawbacks of the approach are also considered. The approach proposed in the article is specific for industrial software systems development. These systems are characterized by different levels of abstraction, which is used on modeling and code development phases. The approach allows to detail the model to the level of the system code, at the same time store the verified model semantics and provide the checking of the whole detailed model. Steps of translating abstract data structures (including transactions, signals and their parameters into data structures used in detailed system implementation are presented. Also the grammar of a language for specifying rules of abstract model data structures transformation into real system detailed data structures is described. The results of applying the proposed method in the industrial technology are shown.The article is published in the authors’ wording.
Actions are performed via utterance, and speech acts apply to speakers' communicative intention to produce an utterance, The simplest purpose of language learning is to communicate with others. Second language learners can have high-level of general language proficiency, when it comes to communicate they might encounter kinds of problems. This paper will discuss a point that it' s whether or not for language learners to speak fluently and sensitively a pragmatic-oriented approach more effective than traditional method. Pragmatic use of language is definitely different from syntactic use of language, Pragmatic training is that essential in teaching environment, for it' s absolute not just to tell learners how to design an idea and organize a sentence, but to instruct learners to say which utterance being proper and appropriate for a certain condition.

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

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.

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

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

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

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...

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

Input- and output-oriented approaches to landscape management have distinct roles for resource protection, environmental restoration, and sustainable land management. Implementing recent proposals for ecosystem management in the western United States involves a synthesis of input and output management. Within the broader context of ecosystem management, input management focuses on tailoring land use to the landscape, whereas output management employs assessments of resource condition to trigger modified management activity once resources are degraded to specified threshold conditions. Current approaches to landscape-scale management, however, tend to rely primarily on output-oriented strategies that are most effective for monitoring environmental conditions. Current uses of input management focus on environmental impact assessments, which generally are site- or project-specific analyses. The compeexity and dynamic nature of ecosystems, and the range of scales over which ecological processes operate, imply that development and incorporation of input-oriented approaches into landscape-scale management is necessary to implement ecosystem management as a strategy for sustainable land use.

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.

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

Approach motivation, a focus on achieving positive outcomes, is related to relative left-hemispheric brain activation, which translates to a variety of right-oriented behavioral biases. In two studies, we found that approach-motivated individuals display a right-oriented bias, but only when they are forced to act quickly. In a task in which they had to divide lines into two equal parts, approach-motivated individuals bisected the line at a point farther to the right than avoidance-motivated individuals did, but only when they worked under high time pressure. In our analysis of all Fédération Internationale de Football Association (FIFA) World Cup penalty shoot-outs, we found that goalkeepers were two times more likely to dive to the right than to the left when their team was behind, a situation that we conjecture induces approach motivation. Because penalty takers shot toward the two sides of the goal equally often, the goalkeepers' right-oriented bias was dysfunctional, allowing more goals to be scored. Directional biases may facilitate group coordination but prove maladaptive in individual settings and interpersonal competition. PMID:22006059
Full Text Available As part of a more comprehensive pilot – study this paper deals with the verification of the first Guided Reading Programme conducted within the Croatian prison system, in the period from June 1st to September 1st, 2012. The subjects were adult male prisoners serving long-term sentences in a medium security prison. The results of the Verbal and Communication Skills, Transcendental Insight and Improving Reading Habits scales of two groups of prisoners were compared, at the initial and final measurement points of the programme. The first group participated in Programme activities (P group, N=8 in contrast with the second group which did not participate in the same activities of Programme (NP group, N=8, but agreed to complete the scales. All the prisoners participated voluntarily. The criteria for the selection of participants in both groups were: completion of four – year secondary school education, preserved cognitive functioning and intrinsic motivation. The data were analysed by the following non-parametric tests: Mann-Whitney test, Chi squared test and programs COCHCOX and METDIF1. Group P showed better results than group NP at the initial (p

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

This paper describes an implementation technique for integrating nested data parallelism into an object-oriented language. Data-parallel programming employs sets of data called 'collections' and expresses parallelism as operations performed over the elements of a collection. When the elements of a collection are also collections, then there is the possibility for 'nested data parallelism.' Few current programming languages support nested data parallelism however. In an object-oriented framework, a collection is a single object. Its type defines the parallel operations that may be applied to it. Our goal is to design and build an object-oriented data-parallel programming environment supporting nested data parallelism. Our initial approach is built upon three fundamental additions to C++. We add new parallel base types by implementing them as classes, and add a new parallel collection type called a 'vector' that is implemented as a template. Only one new language feature is introduced: the 'foreach' construct, which is the basis for exploiting elementwise parallelism over collections. The strength of the method lies in the compilation strategy, which translates nested data-parallel C++ into ordinary C++. Extracting the potential parallelism in nested 'foreach' constructs is called 'flattening' nested parallelism. We show how to flatten 'foreach' constructs using a simple program transformation. Our prototype system produces vector code which has been successfully run on workstations, a CM-2, and a CM-5.

The Spacecraft Control and Operations System 2 (SCOS 2), is intended to provide the generic mission control system infrastructure for future ESA missions. It represents a bold step forward in order to take advantage of state-of-the-art technology and current practices in the area of software engineering. Key features include: (1) use of object oriented analysis and design techniques; (2) use of UNIX, C++ and a distributed architecture as the enabling implementation technology; (3) goal of re-use for development, maintenance and mission specific software implementation; and (4) introduction of the concept of a spacecraft control model. This paper touches upon some of the traditional beliefs surrounding Object Oriented development and describes their relevance to SCOS 2. It gives rationale for why particular approaches were adopted and others not, and describes the impact of these decisions. The development approach followed is discussed, highlighting the evolutionary nature of the overall process and the iterative nature of the various tasks carried out. The emphasis of this paper is on the process of the development with the following being covered: (1) the three phases of the SCOS 2 project - prototyping & analysis, design & implementation and configuration / delivery of mission specific systems; (2) the close cooperation and continual interaction with the users during the development; (3) the management approach - the split between client staff, industry and some of the required project management activities; (4) the lifecycle adopted being an enhancement of the ESA PSS-05 standard with SCOS 2 specific activities and approaches defined; and (5) an examination of some of the difficulties encountered and the solutions adopted. Finally, the lessons learned from the SCOS 2 experience are highlighted, identifying those issues to be used as feedback into future developments of this nature. This paper does not intend to describe the finished product and its operation

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

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

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

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

Software re-engineering and object orientation are two areas of growing interest in the last years. However, while many researchers have focused their interest in the object-oriented design methodologies, a little attention has been paid to the re-engineering towards an object-oriented environment. In this paper, after a brief discussion of the re-engineering issues, we examine the motivations towards object-oriented re-engineering (extendibility, robustness and reusability of the code) and t...

In this article, which takes a person-situation approach, the authors propose and test a cross-level multifoci model of workplace justice. They crossed 3 types of justice (procedural, informational, and interpersonal) with 2 foci (organization and supervisor) and aggregated to the group level to create 6 distinct justice climate variables. They then tested for the effects of these variables on either organization-directed or supervisor-directed commitment, satisfaction, and citizenship behavior. The authors also tested justice orientation as a moderator of these relationships. The results, based on 231 employees constituting 44 work groups representing multiple organizations and occupations, revealed that 4 forms of justice climate (organization-focused procedural and informational justice climate and supervisor-focused procedural and interpersonal justice climate) were significantly related to various work outcomes after controlling for corresponding individual-level justice perceptions. In addition, some moderation effects were found. Implications for organizations and future research are discussed. PMID:15769235
Full Text Available In general, modern programs are large and complex and it is essential that they should be highly reliable in applications. In order to develop highly reliable software, Java programming language developer provides a rich set of exceptions and exception handling mechanisms. Exception handling mechanisms are intended to help developers build robust programs. Given a program with exception handling constructs, for an effective testing, we are to detect whether all possible exceptions are raised and caught or not. However, complex exception handling constructs make it tedious to trace which exceptions are handled and where and which exceptions are passed on. In this paper, we address this problem and propose a mutation analysis approach to develop reliable object-oriented programs. We have applied a number of mutation operators to create a large set of mutant programs with different type of faults. We then generate test cases and test data to uncover exception related faults. The test suite so obtained is applied to the mutant programs measuring the mutation score and hence verifying whether mutant programs are effective or not. We have tested our approach with a number of case studies to substantiate the efficacy of the proposed mutation analysis technique.

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.

Evidence-based medical practice requires that clinical guidelines need to be documented in such a way that they represent a clinical workflow in its most accessible form. In order to optimize clinical processes to improve clinical outcomes, we propose a Service Oriented Architecture (SOA) based approach for implementing clinical guidelines that can be accessed from an Electronic Health Record (EHR) application with a Web Services enabled communication mechanism with the Enterprise Service Bus. We have used Business Process Modelling Notation (BPMN) for modelling and presenting the clinical pathway in the form of a workflow. The aim of this study is to produce spontaneous alerts in the healthcare workflow in the diagnosis of Chronic Obstructive Pulmonary Disease (COPD). The use of BPMN as a tool to automate clinical guidelines has not been previously employed for providing Clinical Decision Support (CDS). PMID:25160142
Full Text Available Abstract Background The objective of this study was to examine the extent of surgical procedures, pathological findings, complications and outcome of patients treated in the last 12 years for gallbladder cancer. Methods The impact of a standardized more aggressive approach compared with historical controls of our center with an individual approach was examined. Of 53 patients, 21 underwent resection for cure and 32 for palliation. Results Overall hospital mortality was 9% and procedure related mortality was 4%. The standardized approach in UICC stage IIa, IIb and III led to a significantly improved outcome compared to patients with an individual approach (Median survival: 14 vs. 7 months, mean+/-SEM: 26+/-7 vs. 17+/-5 months, p = 0.014. The main differences between the standardized and the individual approach were anatomical vs. atypical liver resection, performance of systematic lymph dissection of the hepaticoduodenal ligament and the resection of the common bile duct. Conclusion Anatomical liver resection, proof for bile duct infiltration and, in case of tumor invasion, radical resection and lymph dissection of the hepaticoduodenal ligament are essential to improve outcome of locally advanced gallbladder cancer.

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

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

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

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

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

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

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

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

However, few books exist to teach people how to implement data clustering algorithms. This book was written for anyone who wants to implement or improve their data clustering algorithms.

It is proposed that storage of data as “documents” in DICOM Part 10 formats on industrystandard media could reduce the time and cost of data migration relative to on-line DICOM transfer. The relation to present efforts in developing document-oriented electronic patient records is discussed. DICOM Part 10 files are found to be a suffic...
Full Text Available This study investigates the effect of the entrepreneurial orientation (EO on SME financial performance. The essay also proposes a contingency model to explore the moderating effects of environmental hostility on the relationship between EO and profitability. The study was conducted using a sample of 121 manufacturing SMEs in Spain. Results confirm the positive influence of EO on a firms profitability. More importantly, the impact of EO on SME profitability is higher when there is a fit between EO and the external environment.

Full Text Available Several surveys have indicated that many data warehouses fail to meet business objectives or are outright failures. One reason for this is that requirement engineering is typically overlooked in real projects. This paper addresses data warehouse design from a business perspective by highlighting business strategy analysis, alignment between data warehouse objectives and a firm’s strategy, goal-orientated information requirements’ modelling and how an underlying multidimensional data warehouse model may be derived. A set of guidelines is provided allowing developers to design a data warehouse aligned with a prevailing business strategy. A classic case study is presented.

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

The object-oriented design, as the new approach to formation of mathematical models of real and virtual devices, is directed to construction in program environment of specialized objects, adequately reflecting specificity of a soluble problem. However the given approach universally recognized when creating mass professional program products, is extremely insignificantly applied by the science workers at the mathematical simulation, oriented to laboratory or institute "internal" usage. The rea...

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 la...

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

Several adaptive learning systems are currently available. Nevertheless, most existing e-learning platforms lack efficient alignment to decision makers. Our approach is two-fold. Firstly, we aim to integrate business goals in the selection process of learning concepts. Secondly, we make use of Case Based Reasoning (CBR) approach to learn from past experiences and construct effective adaptive system.

In order to respond to the industrial trend towards service design and delivery, design research must address a vast area partially related to value creation, marketing and network theories. However, compared to the space to be explored, there is little insight available. Thus, this paper, as a...... first step, proposes a way to frame such design research. First, an extensive literature review is performed of over 100 articles on not only PSS-design research but also on related research in fields as PSS in general, service design, innovation, and business models in a broad view. Based on the...... literature analysis, the authors present three crucial dimensions for service oriented design research, i.e. an offer dimension representing products and services, a provider dimension, and a customer/user dimension. In addition, three research targets are proposed; PSS-offer modelling, PSS development, and...
Full Text Available Fundamental to the development of new customer value offerings via web-based commerce is a small firm’s ability to strategically acquire and exploit knowledge. The focus of this paper is the empirical testing of a normative web-based commerce adoption model developed from a review of the extant literature related to electronic marketing, the Internet and the diffusion of new innovations. A preliminary test of the model’s theoretical contentions lent support to its overall focus, but found that the firm’s existing learning capabilities were diminished during the adoption of web-based commerce. Consequently, sub-optimal adoption outcomes were associated with insufficient knowledge development.

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

During the last two years, the experimental database of Frascati Tokamak Upgrade (FTU) has been changed from several points of view, particularly: (i) the data and the analysis codes have been moved from the IBM main frame to Unix platforms making enabling the users to take advantage of the large quantities of commercial and free software available under Unix (Matlab, IDL, etc); (ii) AFS (Andrew File System) has been chosen as the distributed file system making the data available on all the nodes and distributing the workload; (iii) 'One measure/one file' philosophy (vs. the previous 'one pulse/one file') has been adopted increasing the number of files into the database but, at the same time, allowing the most important data to be available just after the plasma discharge. The client-server architecture has been tested using the signal viewer client jScope. Moreover, an object oriented data model (OODM) of FTU experimental data has been tried: a generalized model in tokamak experimental data has been developed with typical concepts such as abstraction, encapsulation, inheritance, and polymorphism. The model has been integrated with data coming from different databases, building an Object Warehouse to extract, with data mining techniques, meaningful trends and patterns from huge amounts of data
Full Text Available An important aspect of the corporate responsibility towards the customers is to ensure the correct value transfer, through the quality and price of the product/service. By using customer satisfaction in order to measure value and the quality provided to customers, this paper proposes a methodology of assisting management decisions in improving business processes. The proposed techniques and tools, specific to quality management, are used for determining the processes which need to be improved or innovated in order to increase customer satisfaction. Thus, the methodology contributes to the creation of a decision-making framework for an efficient orientation of the resources for maximising the generated value and minimising the costs. In order to illustrate its application, we present a study based on the responses regarding satisfaction elements of 679 companies, the customers of a distribution chain in the field of interior fittings. The research highlights the practical method of determining the priority processes for increasing customer satisfaction, taking into account the satisfaction targets and the nature of the necessary actions in order to maximize the created value and to minimize the costs of these processes.

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

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

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

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

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

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

A flood risk assessment for coastal energy infrastructure in the UK with respect to long-term sea-level rise and extreme water levels has been conducted using a combination of numerical modelling approaches (LISFLOOD-FP, SWAB, XBeach-G, POLCOMS). Model outputs have been incorporated into a decision-support tool that enables users from a wide spectrum of coastal stakeholders (e.g. nuclear energy, utility providers, local government, environmental regulators, communities) to explore the potential impacts of flooding on both operational (events to 10 years) and strategic (10 to 50 years) timescales. Examples illustrate the physical and economic impacts of flooding from combined extreme water levels, wave overtopping and high river flow for Fleetwood, NW England; changes in the extent of likely flooding arising from an extreme event due to sea-level rise for Oldbury, SW England; and the relative vulnerability to overtopping and breaching of sea defences for Dungeness, SE England. The impacts of a potential large-scale beach recharge scheme to mitigate coastal erosion and flood risk along the southern shoreline of Dungeness are also examined using a combination of coastal evolution and particle-tracking modelling. The research goal is to provide an evidence base for resource allocation, investment in interventions, and communication and dialogue in relation to sea-level rise to 2500 AD.
Full Text Available Within the classroom context, albeit school or university, intrinsic motivation can effectively be described and changed if a process-oriented approach is employed. The question is posed whether a process-oriented approach to motivation is acceptable to Christian education. To answer this question, intrinsic motivation and the process-oriented approach to motivation are described. A Christian view of self-knowledge and control, which are the main components of a process-oricnted approach to motivation, is subsequently given and the process-oriented approach to motivation is subjected to a Christian evaluation. The conclusions are drawn that this approach can fruitfully be used in Christian education, given that self-knowledge and control arc interpreted within the context of the concept of the student as God’s representative on earth and the fact that God equipped him adequately with cognitive, affective and conative abilities to respond to His call to discover, develop and rule the earth actively.
Full Text Available The Sun is responsible for the eruption of billions of tons of plasma andthe generation of near light-speed particles that propagate throughout the solarsystem and beyond. If directed towards Earth, these events can be damaging toour tecnological infrastructure. Hence there is an effort to understand the causeof the eruptive events and how they propagate from Sun to Earth. However, thephysics governing their propagation is not well understood, so there is a need todevelop a theoretical description of their propagation, known as a PropagationModel, in order to predict when they may impact Earth. It is often difficultto define a single propagation model that correctly describes the physics ofsolar eruptive events, and even more difficult to implement models capable ofcatering for all these complexities and to validate them using real observational data.In this paper, we envisage that workflows offer both a theoretical andpractical framerwork for a novel approach to propagation models. We definea mathematical framework that aims at encompassing the different modalitieswith which workflows can be used, and provide a set of generic building blockswritten in the TAVERNA workflow language that users can use to build theirown propagation models. Finally we test both the theoretical model and thecomposite building blocks of the workflow with a real Science Use Case that wasdiscussed during the 4th CDAW (Coordinated Data Analysis Workshop eventheld by the HELIO project. We show that generic workflow building blocks canbe used to construct a propagation model that succesfully describes the transitof solar eruptive events toward Earth and predict a correct Earth-impact time

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

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

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

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

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

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

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

Previous studies on sperm donation inseminations (D-IUI) show conflict...
Full Text Available We present a new approach to modeling languages for computational biology, which we call the layer-oriented approach. The approach stems from the observation that many diverse biological phenomena are described using a small set of mathematical formalisms (e.g. differential equations, while at the same time different domains and subdomains of computational biology require that models are structured according to the accepted terminology and classification of that domain. Our approach uses distinct semantic layers to represent the domain-specific biological concepts and the underlying mathematical formalisms. Additional functionality can be transparently added to the language by adding more layers. This approach is specifically concerned with declarative languages, and throughout the paper we note some of the limitations inherent to declarative approaches. The layer-oriented approach is a way to specify explicitly how high-level biological modeling concepts are mapped to a computational representation, while abstracting away details of particular programming languages and simulation environments. To illustrate this process, we define an example language for describing models of ionic currents, and use a general mathematical notation for semantic transformations to show how to generate model simulation code for various simulation environments. We use the example language to describe a Purkinje neuron model and demonstrate how the layer-oriented approach can be used for solving several practical issues of computational neuroscience model development. We discuss the advantages and limitations of the approach in comparison with other modeling language efforts in the domain of computational biology and outline some principles for extensible, flexible modeling language design. We conclude by describing in detail the semantic transformations defined for our language.
Full Text Available This paper uses multidimensional environmental value orientations as the segmentation bases for analyzing a natural destination tourism market of the National Forest Recreation Areas in Taiwan. Cluster analyses identify two segments, Acceptance and Conditionality, within 1870 usable observations. Independent sample t test and crosstab analyses are applied to examine these segments’ forest value orientations, sociodemographic features, and service demands. The Acceptance group tends to be potential ecotourists, while still recognizing the commercial value of the natural resources. The Conditionality group may not possess a strong sense of ecotourism, given that its favored services can affect the environment. Overall, this article confirms the use of multidimensional environmental value orientation approaches can generate a comprehensive natural tourist segment comparison that benefits practical management decision making.
Full Text Available This paper describes aspects of the existing tradition of practical work in secondary science education in Sweden, with a focus on inquiry-oriented teaching approaches. Twelve secondary science teachers were interviewed and asked to describe examples of their own teaching practices that they believed constituted inquiry-oriented teaching. The descriptions are analysed in relation to key components of inquiry as conceptualised in the science education literature. In addition, the teachers’ way of talking about their own teaching in relation to inquiry is described and analysed. The results show a wide variety of teaching approaches that are associated with inquiry in different ways. Although inquiry is valued by many teachers, it is also problematic. We discuss the nature of the problems associated with inquiry by the teachers and the possible consequences of these for teacher education, in-service training and curriculum development.

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)

We propose that the psychological states individuals bring into newly formed groups can produce meaningful differences in status attainment. Three experiments explored whether experimentally created approach-oriented mindsets affected status attainment in groups, both immediately and over time. We predicted that approach-oriented states would lead to greater status attainment by increasing proactive behavior. Furthermore, we hypothesized that these status gains would persist longitudinally, days after the original mindsets had dissipated, due to the self-reinforcing behavioral cycles the approach-oriented states initiated. In Experiment 1, individuals primed with a promotion focus achieved higher status in their newly formed groups, and this was mediated by proactive behavior as rated by themselves and their teammates. Experiment 2 was a longitudinal experiment and revealed that individuals primed with power achieved higher status, both immediately following the prime and when the groups were reassembled 2 days later to work on new tasks. These effects were mediated by independent coders' ratings of proactive behavior during the first few minutes of group interaction. Experiment 3 was another longitudinal experiment and revealed that priming happiness led to greater status as well as greater acquisition of material resources. Importantly, these immediate and longitudinal effects were independent of the effects of a number of stable dispositional traits. Our results establish that approach-oriented psychological states affect status attainment, over and above the more stable characteristics emphasized in prior research, and provide the most direct test yet of the self-reinforcing nature of status hierarchies. These findings depict a dynamic view of status organization in which the same group may organize itself differently depending on members' incoming psychological states. PMID:23895266
Full text: The traditional approaches for development of software control system in automation an information technology based on a directly code creation are no longer effective and successful enough. The response to these challenges is the Model Driven Engineering (MDE) or its counter part in the field of architectures Model Driven Architecture (MDA). One of the most promising approach supporting MDE and MDA is UML. It does not specify a methodology for software or system design but aims to provide an integrated modeling framework for structural, functional and behavior descriptions. The success of UML in many object-oriented approaches led to an idea of applying UML to design of multi agent systems. The approach proposed in this paper applies modified Harmony methodology and is based on the combined use of UML profile for system engineering, IEC61499 standard and FIPA standard protocols. The benefits of object-oriented paradigm and the models of IEC61499 standard are extended with UML/SysML and FIPA notations. The development phases are illustrated with the UML models of a simple process control system. The main benefits of using the proposed approach can be summarized as: it provides consistency in the syntax and underlying semantics; increases the potential and likelihood of reuse; supports the whole software development life cycle in the field of process control. Including the SysML features, based on extended activity and parametric diagrams, flow ports and items to the proposed approach opens the possibilities for modeling of continuous system and support the development in field of process control. Another advantage, connected to the UML/MARTE profile is the possibility for analysis of the designed system and detailed design of the hardware and software platform of the modeled application. Key words: object-oriented modeling, control system, UML, SysML, IEC 61499

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

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

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

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

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

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

Many national and regional administrations are currently facing challenges to ensure long-term sustainability of urban water services, as infrastructures continue to accumulate alarming levels of deferred maintenance and rehabilitation. The infrastructure value index (IVI) has proven to be an effective tool to support long-term planning, in particular by facilitating the ability to communicate and to create awareness. It is given by the ratio between current value of an infrastructure and its replacement cost. Current value is commonly estimated according to an asset-oriented approach, which is based on the concept of useful life of individual components. The standard values assumed for the useful lives can vary significantly, which leads to valuations that are just as different. Furthermore, with water companies increasingly focused on the customer, effective service-centric asset management is essential now more than ever. This paper shows results of on-going research work, which aims to explore a service-oriented approach for assessing the IVI. The paper presents the fundamentals underlying this approach, discusses and compares results obtained from both perspectives and points to challenges that still need to be addressed. PMID:27438261
Full Text Available To communicate is the primary goal of most foreign language learning (EFL. As an important component of the four macro skills (listening, speaking, reading and writing, reading should also serve this purpose. However, traditional methodology still dominates extensive reading teaching in most of the universities. To promote a communicative extensive reading class, we may start by designing various tasks and activities. This paper introduces a task-oriented approach in English extensive reading class. According to Nunan, task-oriented teaching involves learners in the classroom to comprehend, manipulate, produce or interact in the target language, but the focus is on the meaning rather than the form. In light of psycholinguistic model and schema theory model, the methodology covers information-gap activity, opinion-gap activity and reasoning-gap activity which can be run in the class. The task-approaches make the interaction between teacher and students, students and students more active and meaningful. Skills of reading to solve communicative problems are always treated consciously. This approach may hopefully result in some improvement on the teaching of English reading.

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

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

Objective The abuse of illegal substances by youths in Taiwan has become a major public health issue. This study explores the outcomes (relapse rate and academic or social status) of a family-oriented therapy program conducted for substance-using youths who were referred by a judge to participate in it. Methods The present study includes 121 participants categorized into three groups: 36 youths underwent a weekly ten-session outpatient motivational enhancement psychotherapy (MEP) group program; 41 youths participated in a program that combined the aforementioned MEP program with an additional weekly ten-session parenting skill training (PST) program for their guardians (MEP + PST group); and 44 adolescents who received standard supervision by the court served as the control group. All participants were followed-up for a maximum of 2 years. Results Of the 121 participants (mean age: 16.1±1.1 years), 33.1% relapsed into substance use during the follow-up period. The probability of relapse did not differ significantly between the MEP group (36.1%) and the control group (40.9%), but the youths in the MEP + PST group (22.0%) were at a lower risk of relapse than the control group participants (adjusted hazard ratio =0.48, 95% confidence interval [CI] =0.21–1.09). By the end of the study follow-up period, participants in both the MEP group and the MEP + PST group were more likely to be attending school (MEP group: adjusted odds ratio [aOR] =6.61, 95% CI =1.60–27.35; MEP + PST group: aOR =8.57, 95% CI =1.94–37.82) or employed (MEP group: aOR =7.75, 95% CI =1.95–30.75; MEP + PST group: aOR =7.27, 95% CI =1.76–29.97), when compared to the control group. Conclusion This study revealed that a family-oriented treatment approach may be a more effective option for preventing youths’ relapsing into substance abuse. In comparison to individuals who received standard supervision by the court, those who received MEP experienced a better school attendance or social

Manual and locomotion tasks, differing in time duration, measurement volume, presence/absence of static phases, and out-of-plane movements, were performed by six subjects, and recorded by one unit located on the forearm or the lower trunk, respectively. Two sensor fusion methods, representative of the stochastic (Extended Kalman Filter and complementary (Non-linear observer filtering, were selected, and their accuracy was assessed in terms of attitude (pitch and roll angles and heading (yaw angle errors using stereophotogrammetric data as a reference. The sensor fusion approaches provided significantly more accurate results than gyroscope data integration. Accuracy improved mostly for heading and when the movement exhibited stationary phases, evenly distributed 3D rotations, it occurred in a small volume, and its duration was greater than approximately 20 s. These results were independent from the specific sensor fusion method used. Practice guidelines for improving the outcome accuracy are provided.

Sexual orientation has two key aspects: actual sexual experiences (e.g., attraction, fantasy, and behavior) and beliefs about those sexual experiences (self-perceived sexual orientation). It is self-perceived sexual orientation that is most often measured and used to understand the mental, physical, and behavioral correlates of sexual orientation. While evidence suggests that features of the social context (e.g., social norms) are related to self-perceived sexual orientation, to date there is...

Increasing the understanding of a proteome and how its protein composition is affected by for example different diseases, such as cancer, has the potential to improve strategies for early diagnosis and therapeutics. The Global Proteome Survey or GPS is a method that combines mass spectrometry and affinity enrichment with the use of antibodies. The technology enables profiling of complex proteomes in a species independent manner. The sensitivity of GPS, and other methods relying on affinity enrichment, is largely affected by the activity of the exploited affinity reagent. We here present an improvement of the GPS platform by utilizing an antibody immobilization approach which ensures a controlled immobilization process of the antibody to the magnetic bead support. More specifically, we make use of an antibody format that enables site-directed biotinylation and use this in combination with streptavidin coated magnetic beads. The performance of the expanded GPS platform was evaluated by profiling yeast proteome samples. We demonstrate that the oriented antibody immobilization strategy increases the ability of the GPS platform and results in larger fraction of functional antibodies. Additionally, we show that this new antibody format enabled in-solution capture, i.e. immobilization of the antibodies after sample incubation. A workflow has been established that permit the use of an oriented immobilization strategy for the GPS platform. PMID:26703809
Full Text Available For large software systems, testing phase seems to have profound effect on the overall acceptability and quality of the final product. The success of this activity can be judged by measuring the testability of the software. A good measure for testability can better manage the testing effort and time. Different Object Oriented Metrics are used in measurement of object-oriented testability but none of them is alone sufficient to give an overall reflection of software testability. Thus an integrated measure considering the effect of all these measures is required to well define the testability. The paper combines OO software metric values into a single overall value (called Testability Index that can be used to calculate the testability of a class. The approach uses fuzzy techniques and concepts (fuzzification of crisp metric values, inference and aggregation, defuzzification of fuzzy output. We include empirical data of testing time of 25 different Java classes, which proves that individual metric values are not sufficient to arrive at the testability of a class and validates the testability index as a good integrated measure for arriving at the testability of the class.

What are the constructs that underlie affective experiences? Some authors have suggested Valence and Activation, whereas others have suggested Positive Activation and Negative Activation-both approaches are represented by different axis orientations in traditional two-mode (People x Adjectives) factor analysis. The authors provide new evidence for this debate by using three-mode (People x Adjectives x Occasions) parallel factor (PARAFAC) analysis to determine the appropriate axes (and hence constructs) for representing affective experiences. Unlike traditional factor analysis, with PARAFAC different orientations of the axes fit the data differently so it is possible to determine the best fitting axes. In Study 1, the authors assessed the extent to which the PARAFAC procedure was able recover the axes defining a two-dimensional factor space under different conditions. In both Study 2 (N = 112) and Study 3 (N = 349), undergraduate students rated their emotional states on a variety of occasions. The best fitting axes for two-dimensional affective space were Valence and Activation in both studies. Exploration of higher dimensional solutions in Study 3 revealed a three-factor solution that, in addition to an activation factor, supported the separation of positive and negative emotions.

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

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

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.
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.

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

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

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

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.

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

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

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

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

Full Text Available Power management systems for embedded devices can be developed in real-time operating system (RTOS or in applications. If power management policies are applied in operating system (OS, then designers and developers will not have to worry about complex power management algorithms and techniques. They can rather concentrate on application development. The OS contains specific and accurate information about the various tasks being executed. An RTOS further has a comprehensive set of power management application programming interfaces (APIs for both device drivers and applications within a power management component. Therefore, it is logical to place policies and algorithms in the OS that can place components not being used into lower power states. This can significantly reduce the system energy consumption. We present here an abstract model of a system power manager (PM, device power managers, and application power managers. We present relationship and interactions of these managers with each other using Unified Modeling Language (UML class diagrams, sequence diagrams and state charts. We recommend that the PM must be implemented at the OS level in any embedded device. We also recommend the interfaces for interactions between PM and the devices power manager, as well as PM and application power manager. Device driver and application developers can easily use this object oriented approach to make the embedded system more power efficient, easy to maintain, and faster to develop.
Full Text Available Conventionally, user authentication and access control mechanisms would be almost enough, to handle security for stand-alone computers and small networks. Ad hoc networks are illustrated by multi-hop wireless connectivity and recurrently changing network topology which have made them infrastructure less. Adding trust to the existing security infrastructures would improvise the security of these environments. Describing trust relations and their sub-components using ontologies, creates a methodology and mechanism in order to efficiently design and engineer trust networks. This is going tobe used as a service for providing trust for ad hoc network at any level i.e. routing, authentication or access control. A trust oriented security framework for adhoc network using ontological engineering approach is proposed by modeling ad hoc network, the OLSR (Optimized Link State Routing protocol and trust model as OWL (Ontology Web language ontologies, which are integrated using Jena. In this model, a trustor can calculate its trust about trustee and use the calculated trust values to make decisions depending on the context of the application or interaction about granting or rejecting it. A number ofexperiments with a possible implementation of suggested framework are performed to make out the characteristics of the trust model and its effect on the ad hoc network operations.

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

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

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

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

The federation of databases is not a new endeavor. Great strides have been made e.g. in the health and astrophysics communities. Reviews of those successes indicate that they have been able to leverage off key cross-community core concepts. In its simplest implementation, a federation of databases with identical base schemas that can be extended to address individual efforts, is relatively easy to accomplish. Efforts of groups like the Open Geospatial Consortium have shown methods to geospatially relate data between different sources. We present here a summary of CHRONOS's (http://www.chronos.org) experience with highly heterogeneous data. Our experience with the federation of very diverse databases shows that the wide variety of encoding options for items like locality, time scale, taxon ID, and other key parameters makes it difficult to effectively join data across them. However, the response to this is not to develop one large, monolithic database, which will suffer growth pains due to social, national, and operational issues, but rather to systematically develop the architecture that will enable cross-resource (database, repository, tool, interface) interaction. CHRONOS has accomplished the major hurdle of federating small IT database efforts with service-oriented and XML-based approaches. The application of easy-to-use procedures that allow groups of all sizes to implement and experiment with searches across various databases and to use externally created tools is vital. We are sharing with the geoinformatics community the difficulties with application frameworks, user authentication, standards compliance, and data storage encountered in setting up web sites and portals for various science initiatives (e.g., ANDRILL, EARTHTIME). The ability to incorporate CHRONOS data, services, and tools into the existing framework of a group is crucial to the development of a model that supports and extends the vitality of the small- to medium-sized research effort that is

The growing importance of oil spill detection as part of a rapid response system to oil pollution requires the ongoing development of algorithms. The aim of this study was to create a methodology for improving manual classification at the scale of entire water bodies, focusing on its repeatability. This paper took an object-oriented approach to radar image analysis and put particular emphasis on adaptation to the specificity of seas like the Baltic. Pre-processing using optimised filters enhanced the capability of a multilevel hierarchical segmentation, in order to detect spills of different sizes, forms and homogeneity, which occur as a result of shipping activities. Confirmed spills detected in ENVISAT/ASAR images were used to create a decision-tree procedure that classifies every distinct dark object visible in SAR images into one out of four categories, which reflect growing probability of the oil spill presence: look-alikes, dubious spots, blurred spots and potential oil spills. Our objective was to properly mark known spills on ASAR scenes and to reduce the number of false-positives by eliminating (classifying as background or look-alike) as many objects as possible from the vast initial number of objects appearing on full-scale images. A number of aspects were taken into account in the classification process. The method's performance was tested on a group of 26 oil spills recorded by HELCOM: 96.15% of them were successfully identified. The final target group was narrowed down to about 4% of dark objects extracted from ASAR images. Although a specialist is still needed to supervise the whole process of oil spill detection, this method gives an initial view, substantial for further evaluation of the scenes and risk estimation. It may significantly accelerate the pace of manual image analysis and enhance the objectivity of assessments, which are key aspects in operational monitoring systems.
Full Text Available The International Atomic Energy Agency (IAEA launched a Coordinated Research Program in 10 developing countries including Pakistan involving small scale market oriented dairy farmers to identify and prioritize the constraints and opportunities in the selected dairy farms, develop intervention strategies and assess the economic impact of the intervention. The interventions in animal health (control of mastitis at sub-clinical stage and reduction in calf mortality, nutrition (balanced feed reproduction (mineral supplementation, and general management (training of farmers were identified and implemented in a participatory approach at the selected dairy farms. The calf mortality was reduced from 35 to 13 percent up to the age of 3 months. Use of Alfa Deval post milking teat dips reduced the incidence of sub-clinical mastitis from 34 to 5% showing economical benefits of the interventions. Partial budget technique was used to analyze its impact in the registered herds. The farmers recorded monthly quantities of different feed ingredients and seasonal green fodder offered to the animals. From this data set total metabolizeable energy requirements and availability from feed were computed which revealed that animals were deficient in metabolizeable energy in all locations. This was also confirmed by seasonal variation in body condition scoring. At some selected farms the mineral mixture supplement was introduced which exhibited increased milk yield by 5 % in addition to shorten service period by 30 days. Three sessions of training were arranged to train the farmers to care new born calves, daily farm management and detect the animals in heat efficiently to enhance the over all income of the farmers. The overall income of the farm was increased by 40%.
Full Text Available Several studies have attempted to characterize morphological brain changes due to chronic pain. Although it has repeatedly been suggested that longstanding pain induces gray matter modifications, there is still some controversy surrounding the direction of the change (increase or decrease in gray matter and the role of psychological and psychiatric comorbidities. In this study, we propose a novel, network-oriented, meta-analytic approach to characterize morphological changes in chronic pain. We used network decomposition to investigate whether different kinds of chronic pain are associated with a common or specific set of altered networks. Representational similarity techniques, network decomposition and model-based clustering were employed: i to verify the presence of a core set of brain areas commonly modified by chronic pain; ii to investigate the involvement of these areas in a large-scale network perspective; iii to study the relationship between altered networks and; iv to find out whether chronic pain targets clusters of areas. Our results showed that chronic pain causes both core and pathology-specific gray matter alterations in large-scale networks. Common alterations were observed in the prefrontal regions, in the anterior insula, cingulate cortex, basal ganglia, thalamus, periaqueductal gray, post- and pre-central gyri and inferior parietal lobule. We observed that the salience and attentional networks were targeted in a very similar way by different chronic pain pathologies. Conversely, alterations in the sensorimotor and attention circuits were differentially targeted by chronic pain pathologies. Moreover, model-based clustering revealed that chronic pain, in line with some neurodegenerative diseases, selectively targets some large-scale brain networks. Altogether these findings indicate that chronic pain can be better conceived and studied in a network perspective.
Full Text Available Evidence points to the fact that frequent resignation of project engineers from construction companies is primarily the result of dissatisfaction with the factors that shape the salary scale. This research aims to identify the major influencing factors in merit based salary calculation systems for knowledge-oriented engineers so as to more accurately reflect their contribution to construction projects. Results from a questionnaire sent to managers, engineers and HR professionals throughout the Iranian construction industry revealed that while there was overall agreement on principles to a merit-based approach, engineers in particular identified ‘professional skills’, ‘experience’ and ‘creativity’. Management-oriented parties should take into account engineer perspectives in order to more accurately value the knowledge-oriented contribution of these workers to construction projects. This research provides a basis for understanding the key factors in the merit based salary scale formulation through the construction industry.

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

International audience Programming large systems requires to cut them in smaller pieces (modules, objects, components, agents, ...). In all but trivial cases, choices must be made about what will be the pieces, and some aspects are inevitably spread out over several parts. In Object-Oriented Programming, these have been identified as "Crosscutting Concerns", and Aspect-Oriented Programming is about a reunification of these transversal aspects of the system. In multi-agent programming, one ...

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

An analysis and some generalizations of approaches to risk assessments are presented. Interconnection between different interpretations of the "risk" notion is shown, and the possibility of applying the fuzzy set theory to risk assessments is demonstrated. A generalized formulation of the risk assessment notion is proposed in applying risk-oriented approaches to the problem of enhancing reliability and safety in nuclear power engineering. The solution of problems using the developed risk-oriented approaches aimed at achieving more reliable and safe operation of NPPs is described. The results of studies aimed at determining the need (advisability) to modernize/replace NPP elements and systems are presented together with the results obtained from elaborating the methodical principles of introducing the repair concept based on the equipment technical state. The possibility of reducing the scope of tests and altering the NPP systems maintenance strategy is substantiated using the risk-oriented approach. A probabilistic model for estimating the validity of boric acid concentration measurements is developed.
Full Text Available Several emotion theorists suggest that valenced stimuli automatically trigger motivational orientations and thereby facilitate corresponding behavior. Positive stimuli were thought to activate approach motivational circuits which in turn primed approach-related behavioral tendencies whereas negative stimuli were supposed to activate avoidance motivational circuits so that avoidance-related behavioral tendencies were primed (motivational orientation account. However, recent research suggests that typically observed affective stimulus–response compatibility phenomena might be entirely explained in terms of theories accounting for mechanisms of general action control instead of assuming motivational orientations to mediate the effects (evaluative coding account. In what follows, we explore to what extent this notion is applicable. We present literature suggesting that evaluative coding mechanisms indeed influence a wide variety of affective stimulus–response compatibility phenomena. However, the evaluative coding account does not seem to be sufficient to explain affective S–R compatibility effects. Instead, several studies provide clear evidence in favor of the motivational orientation account that seems to operate independently of evaluative coding mechanisms. Implications for theoretical developments and future research designs are discussed.

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

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