Operator Activity

In the paper the methodology in the assessment of operator activities in man-machine systems is offered. The approach offered is directed to the solution of the contradiction between the definition of qualifying requirements to operator activity in indices of its quality and existing methods ensuring the assessment of the functional efficiency of activity. The indices of the quality assessment of operator activity and charac-teristics of qualifying requirements for operators of “man-machine” systems are defined. In the paper there is shown a structural chart of a program complex for the assessment of operator activity quality. Methods of a statistical modeling suitable for the solution of the problem of accuracy increase in the assessment of operator activities quality are considered. Basic requirements and assumptions used in the course of the formation of a model of the operator activity and assessment of its quality are defined. The assessments of quality indices of operator activity obtained on the model can be specified using various procedures increasing the efficiency of statistical method modeling. A statistical modeling allows imitating the activity processes actually without limitation of the amount of factors taken into account and without demanding the presentation of inves-tigated dependences in an actual view regarding a desired variable. A variety of used in practice indices and methods of their assessment is determined first of all by a varied structure of existing kinds of operator activity and their purposefulness.

Semantic Distinction

Abstract French suffixations in -age, -ion and -ment are considered roughly equivalent, yet some differences have been pointed out regarding the semantics of the resulting nominalizations. In this study, we confirm the existence of a semantic distinction between them on the basis of a large scale distributional analysis. We show that the distinction is partially determined by the degree of technicality of the denoted action: -age nominals tend to be more technical than -ion ones. We examine this hypothesis through the statistical modeling of technicality. To this end, we propose a linguistic definition of technicality, which we implement using empirical, quantitative criteria estimated in corpora and lexical resources. We show to what extent the differences with respect to these criteria adequately approximate technicality. Our study indicates that this definition of technicality, while amendable, provides new perspectives for the characterization of action nouns.

Mesh Database

This chapter concerns the visual saliency and the perceptual quality assessment of 3D meshes. Firstly, the chapter proposes a definition of visual saliency and describes the state-of-the-art methods for its detection on 3D mesh surfaces. A focus is made on a recent model of visual saliency detection for 3D colored and non-colored meshes whose results are compared with a ground-truth saliency as well as with the literature's methods. Since this model is able to estimate the visual saliency on 3D colored meshes, named colorimetric saliency, a description of the construction of a 3D colored mesh database that was used to assess its relevance is presented. The authors also describe three applications of the detailed model that respond to the problems of viewpoint selection, adaptive simplification and adaptive smoothing. Secondly, two perceptual quality assessment metrics for 3D non-colored meshes are described, analyzed, and compared with the state-of-the-art approaches.

Development And Validation

Introduction: The lack of tools for quality assessment of genetic counselling is recognized in national and international studies. The correlation of quality of healthcare practice with greater satisfaction of patients and affected families is also well established. The present study describes the development and validation of the first Portuguese scale for quality assessment of genetic counselling practice. It encompasses a proposal of a new tool for the evaluation of the process by professionals.Material and Methods: The definition of an initial pool of items and their organization was based on a literature review and identification of the main genetic counselling dimensions as well as the theoretical dimensions of the Reciprocal Engagement Model. After a pre-test validation the scale was submitted to psychometric validation using a sample of 30 participants who evaluated 81 genetic counselling sessions.Results: Based on statistical and empirical criteria the best items were selected. The final 50 items- version comprises five dimensions: education, counselees’ characteristics and decision-making, therapeutic relationship, effects of the process on the counselees andservices organization.Discussion: Results showed consistent psychometric properties of the scale supported on theoretical and practice concepts of genetic counseling. The reduced number of participants involved in psychometric validation is a limitation of the study, which reflected thereduced number of professionals in genetic healthcare services.Conclusion: The scale proposed at this study is a novel and multidimensional instrument that aimed to contribute to the improvement of genetic counselling practice in Portugal.

Peirce is often credited with having formulated a pragmatic theory of truth. This can be misleading, if it is assumed that Peirce was chiefly interested in providing a metaphysical analysis of the immediate conditions under which a belief or proposition is true, or the conditions under which a proposition or belief is said to be madetrue. Cheryl Misak has exposed the subtleties in Peirce's discussion of truth, especially showing the difficulties faced by any ascription to him of an analytic definition of truth. In this paper I follow Misak in urging that Peirce's contribution to the philosophical discussion about the nature of truth was not of that kind. What makes his pragmatic approach distinctive is that rather than attempting to state the nature of truth per se, it attempts to uncover the beliefs and expectations we commit ourselves to when we make specific claims that such and such is true or is the case.

Machining of different materials brings increasing of productivity, economical effectivity and quality of work piece. Constant development of Robotics and information systems brings new views of using robots in a process of production. Instead of using robots for a purpose of manipulation with work pieces, it is possible to use a robot directly for machining. Robotics machining technology has its advantage in application, which represents an adequate alternative in machining of metals on tradition of machine systems. The aim of the suggested plan of the experiment is to identify the optimal approach and combinations of each parameter during milling.

Measuring the quality of the urban environment has been a matter of research rooted in different fields of knowledge. Several methods and indicators have been deployed through the years, as have horizontal approaches from mixed perspectives. However, currently established indexes to measure urban performance depend on the actual definition of quality and on the weighted relevance of the different features influencing it. This contribution compares the level of emphasis paired by established indexes to measure urban quality, in contrast to what people mention the most when asked about what they like or dislike about the urban environment. The underlying idea is to obtain first-hand information about the way people make decisions about their movements in urban space. As a result, we observe a lack of correlation between the two groups of indicators, and between the key urban elements driving positive and negative emotions. In conclusion, we observe a tendency of people to perceive and report individual physical elements, rather than intangible concepts like safety or comfort.
