    This report contains information on the activities of the Artificial Intelligence Research Branch (FIA) at NASA Ames Research Center (ARC) in 1992, as well as planned work in 1993. These activities span a range from basic scientific research through engineering development to fielded NASA applications, particularly those applications that are enabled by basic research carried out in FIA. Work is conducted in-house and through collaborative partners in academia and industry. All of our work has research themes with a dual commitment to technical excellence and applicability to NASA short, medium, and long-term problems. FIA acts as the Agency's lead organization for research aspects of artificial intelligence, working closely with a second research laboratory at the Jet Propulsion Laboratory (JPL) and AI applications groups throughout all NASA centers. This report is organized along three major research themes: (1) Planning and Scheduling: deciding on a sequence of actions to achieve a set of complex goals and determining when to execute those actions and how to allocate resources to carry them out; (2) Machine Learning: techniques for forming theories about natural and man-made phenomena; and for improving the problem-solving performance of computational systems over time; and (3) Research on the acquisition, representation, and utilization of knowledge in support of diagnosis design of engineered systems and analysis of actual systems

    A practical theological study of community pastoral work : an ecosystemic perspective

    Get PDF
    Chapter 1 describes practical theology as a communicative operational science and stresses how important it is that a hermeneutical and narrative approach compliments it. It is shown that pastoral work must be launched from the church community. The premise is that the Enlightenment paradigm causes a reductionistic, individualistic and denominational approach to pastoral work. A holistic, comprehensive and ecologically orientated approach is proposed. Chapter 2 discusses the need for an ecosystemic approach as a metaparadigrn for practical theology in terms of the move away from the Newtonian view of science and the post-modem critiques of a technocratic society. This is supported by developments in systemic family therapy, constructionism and community psychology. Chapter 3 describes an interrelated ecclesiology as a base theory for practical theology and pastoral work with reference to the church's interrelation with society and the need to include an anthropology as part of an ecclesiology. This interrelationship implies that the serving (diakonia) and caring (koinonia) functions of the church should converge, forming a diaconal pastorate. In chapter 4 the secularised modem world-vie\v and the traditional African world-view, both functioning in South Africa, are employed to shed light upon the importance of the concept community for the church's pastoral work. The term community is broadened to include the idea of networking, emphasisingg that community is more than geographical proximity. Chapter 5 is a quantitative investigation. by means of a questionnaire, of the views (ecosystemic/non-ecosystemic) of pastoral workers regarding the church and of pastoral work. Chapter 6 discusses the implications of a community pastoral work approach. Pastoral work has a serving-caring role, but should also function prophetically, to conscientise. sensitise and empower people. The church as a healing community must become the springboard from which pastoral actions can face the challenge of AIDS (chapter 7). This will require the church to shift its paradigm from the reductionist, individualist approach, presently prevalent in society and church pastoral actions, to an all-encompassing. holistic one.Philosophy, Practical and Systematic TheologyTh.D.

    Endogenous development: a model for the process of man-environment transaction

    Get PDF
    Iran is currently subject to a number of adverse factors affecting good development in the built environment: population explosion, oil- dependent economy, finite resources, war and natural disasters, etc. The object of the study is to research a development model appropriate to the Country's needs for a proactive system of building environment. This model is not specific to Iran and, as the case studies and the discourse of the thesis indicate, is universal. However, the author suggests that the validity of development approaches will not be determined as a result of theoretical and ideological debate but in the realm of practice. Therefore, he has explored diverse ways in which professionals in the built environment can provide an analytical survey of the problems that beset them. An attempt has been made to bring these various elements into perspective and offer a model of 'endogenous development'.The process for achieving a viable, exciting and humane built environment is very complex and calls for contributions from many individuals and small multi -disciplinary groups. Beside professionals contributions (which is accomplished by deduction inference), there is a need for people's participation in design process (which is accomplished either by deduction or by abduction inferences). This participatory approach can also help shifting the process of design towards a wider domain that of the 'production process' (which is accomplished by abduction and induction inferences). Production process is the first paradigm of the model of endogenous development and is a manifestation of a feedback mechanism and acts as an open - ended living system. The second is 'supply- demand' paradigm which shows the relationships between the components of a system or between different systems in surface- structuresThis model is directed at society's development, not just its economic growth, but it does not preclude the possibility of such growth. The reduction of the problems' effect in an endogenous development is viewed more as a way of improving the quality of life than of increasing the standard of living. Nowadays, people are passive recipients in the consumer society and are totally dependent on others for their survival. This style of living is assumed to project an image of economic development and higher productivity, but there is a confrontation of preadjusted commodities which are the products of others. That is because the process of production is not natural (i.e. a closed loop cyclic process via feedback control). It is artificial (i.e. an open -loop linear process via a feed -forward control) which may not help satisfying the user's needs and wants entirely. In the built environment, the great majority have no say in the planning and design of their homes or places of work.Accordingly, endogenous development offers a framework within which the necessity of employing the people's creative power in building their environment is explained. It is based on the assumption that each individual and society's knowledge and experiences play a central and mediating role between professionals' perceptions of the environment and a series of preferences judgements or choices they might make towards and within that environment. Indigenous knowledge and cultural attributes of traditional societies and the organizational capabilities of traditional polities are essential in qualification of the development plans, which are also evaluated and assessed by this proposed framework

    Colour/space : its quality management in architecture : the colour/space unity as an unity of visual communication

    In external city environment areas there is a poor understanding and often noconscious use of colour.The experts that work with colour, in terms of the built environment either as projectmakers,or as managers (decision-makers), are poorly prepared to deal with it.As an answer they minimise the problem of colour in architecture, especially inexteriors, simply by omission; or, they introduce colour mostly without criteria - insome projects colour plays only a cosmetic role - supposedly aesthetical.Most project-makers do not consider colour as an integral part of the globaldesign process.Colour theory and teaching courses have been considered supplemental to themainstream of architectural education; for most part of the students of architectureor landscaping architecture, colour remains a matter of individual taste.People in general are very conscious of colour and texture in the built environmentand they really like variations (as some studies done in Sweden (Koller 1981;Mahnke 1993) have already showed). They are negative and critical of austere,colourless environments in our cities; also colour has psycho-therapeutic effectsthat can be utilised to meet the physiological needs of people living in crowdedenvironments.Colour is one of the basic components of the environment which influences life qualityand it can be approached from different perspectives and different disciplines.This research addresses the issue of colour in the architecture of the built environmentanalysing the behaviour of the unity which results from the straight relationship betweencolour and space(as quantity of colour): the Colour/Space Unity. The investigationshows not only the existence of this unity, but also that it is a unity of visualcommunication.In terms of allocating the findings and interpretations through a review of therelevant theory, the author uses a survey methodology - a full test response questionnaire to a wide range of members of society (to test theory) and semistructured interviews with a panel of experts(as a feasibility test of the questionnairedesign and contents). The questionnaire findings are used to test the theoreticalposition through further comments from the expert panel.The research presents as results, not only the existence and importance of thecolour/space unity, as a visual communicational one, such as the levels ofarticulation of the messages in the built environment or the contrast in the relationshipbetween qualification and quantification in colour/space language; but itdemonstrates the major importance of the colour/space unity in the architecturalproject and in the colour planning management within the built environment

    Evidence-based Education: The development of a model to use protocols and small-scale aggregated trials to create a prospective cumulative meta-analysis as an evidence base for interventions.

    Get PDF
    In education, there has been a worldwide increase in the use of evidence in education to inform policy and practice. In the USA, bodies such as the Institute of Educational Sciences’ (IES) What Works Clearinghouse (WWC), the Best Evidence Encyclopaedia (BEE) and the Department General Administrative Regulations (EDGAR) and in the UK the Education Endowment Foundation (EEF) have been established to inform education decision making. The global increase in the use of evidence in education is based on the premise that if programmes are selected on the basis of more robust evidence, using these tested interventions should increase the chance of positive outcomes if they are deployed in other schools and contexts. The aim of this thesis is to explore evidence-based education in the literature review before proposing a new theoretical model for evidence generation, introducing the use of protocols and small-scale aggregated trials linked to a prospective cumulative meta-analysis (PCM). The application of a PCM allows replication as a way to test how likely the intervention effect sizes will translate when they are tested using large scale randomised controlled trials and also as a method to test stability and improve dissemination after the initial research. The thesis includes two primary research studies for online cross-age peer tutoring across the transition boundary between primary and secondary schools and online small group teaching. The purpose of the trials were to test the implementation of the methodology for the use of protocols and small-scale aggregated trials linked to a prospective cumulative meta-analysis (PCM). Study One focuses on online peer tutoring across the transition for primary and secondary pupils and Study Two investigates the effectiveness of online small group teaching for mathematics. The thesis demonstrates how the use of the model can be used to increase replication in the testing phase of an intervention, using empirical evidence from the online peer tutoring trials involving data collected across three cohorts of schools in an academic year. The impact of this research will provide an alternative testing framework for deciding in future trials if the evidence is robust for the commissioning of large scale randomised controlled trials in education
