The 1990 progress report and future plans
This document describes the progress and plans of the Artificial Intelligence Research Branch (RIA) at ARC in 1990. Activities span a range from basic scientific research to engineering development and to fielded NASA applications, particularly those applications that are enabled by basic research carried out at RIA. Work is conducted in-house and through collaborative partners in academia and industry. Our major focus is on a limited number of research themes with a dual commitment to technical excellence and proven applicability to NASA short, medium, and long-term problems. RIA acts as the Agency's lead organization for research aspects of artificial intelligence, working closely with a second research laboratory at JPL and AI applications groups at all NASA centers
Systematizing Gibsonian affordances in robotics: an empirical, generative approach derived from case studies in legged locomotion
A Gibsonian theory of affordances commits to direct perception and the mutuality of the agent-environment system. We argue that there already exists a research program in robotics which incorporates Gibsonian affordances. Controllers under this research program use information perceived directly from the environment with little or no further processing, and implicitly respect the indivisibility of the agentenvironment system. Research investigating the relationships between environmental and robot properties can be used to design reactive controllers that provably allow robots to take advantage of these affordances. We lay out key features of our empirical, generative Gibsonian approach and both show how it illuminates existing practice and suggest that it could be adopted to facilitate the systematic development of autonomous robots. We limit the scope of projects discussed here to legged robot systems but expect that applications can be found in other fields of robotics research.
This paper was presented at the 2nd International Workshop on Computational Models of Affordances at ICRA 2019.

Theory of deferred action: Agent-based simulation model for designing complex adaptive systems
Deferred action is the axiom that agents act in emergent organisation to achieve predetermined goals. Enabling deferred action in designed artificial complex adaptive systems like business organisations and IS is problematical. Emergence is an intractable problem for designers because it cannot be predicted. We develop proof-of-concept, conceptual proto-agent model, of emergent organisation and emergent IS to understand better design principles to enable deferred action as a mechanism for coping with emergence in artefacts. We focus on understanding the effect of emergence when designing artificial complex adaptive systems by developing an exploratory proto-agent model and evaluate its suitability for implementation as agent-based simulation
Make-or-Buy Decisions in Patent Related Services
Among the most prominent theoretical frameworks dealing with the economic
underlyings of firmsâ make-or-buy decisions are Transaction Cost Economics (TCE) and the Resourced Based View (RBV). Relying on panel data covering 107 European firms over eight years I test predictions from both TCE and
RBV with regard to the outsourcing of patent related services simultaneously. Modelling the share of outsourced patent applications in a Negative Binomial Panel Regression Model I find joint explanatory power of both approaches. My findings support previous literature arguing for an integration of TCE and RBV to a comprehensive theoretical framework of firms make-or-buy decisions
Strengthening the Scientific Foundations of Professional Psychology: Time for the Next Steps
The field of professional psychology has been tremendously successful, although it has also been characterized by many competing preparadigmatic theoretical orientations, which have led to a great deal of contention as well as conflicting views regarding psychological development, functioning, and behavior change. There is now widespread agreement regarding scientific explanations of many psychological processes, however, and, consequently, it is time to update the basic conceptual frameworks used for professional psychology education and practice. Replacing the traditional reliance on an array of theoretical orientations with a science-based biopsychosocial framework would resolve many of the contradictions and conflicts that characterized the preparadigmatic era and would also provide a common perspective for unifying psychologists around a shared approach to practice, research, and training
Austrian Economics, Evolutionary Psychology and Methodological Dualism: Subjectivism Reconsidered
The methodological individualism and subjectivism of the Austrian tradition in economics is often associated with a methodological dualism, i.e. the claim that the nature of its subject matter, namely purposeful and intentional human action, requires economics to adopt a methodology that is fundamentally different from the causal explanatory approach of the natural sciences. This paper critically examines this claim and advocates an alternative, explicitly naturalistic and empiricist outlook at human action, exemplified, in particular, by the research program of evolutionary psychology. It is argued that, within the Austrian tradition, a decidedly naturalistic approach to subjectivism can be found in F.A. Hayek's work. --Austrian economics,evolutionary psychology,methodological dualism,subjectivism
Hermeneutic single case efficacy design: A systematic review of published research and current standards
open4siThis article systematically reviews the methodological characteristics of Hermeneutic Single Case Efficacy
Design (HSCED) studies published in peer-reviewed journals. HSCED provides researchers with a
flexible and viable alternative to both between-groups and within-subject experimental designs. This article
includes a description of the evolution of the methodology distinctive to HSCED; a discussion of results
of HSCED studies considered within a framework of contemporary standards and guidelines for systematic
case study research; a presentation of recommendations for key characteristics (e.g., diagnosis,
hermeneutic analysis, adjudication procedure). Overall, the aim is provide researchers and reviewers with
a resource for conducting and evaluating HSCED research. The results of a systematic review of 13 studies
suggests that published HSCED research meets contemporary criteria for systematic case study research.
Hermeneutic analysis and adjudication emerged as areas of HSCED practice characterized by a
diversity of procedures. Although consensus exists along key dimensions of HSCED, there remains a need
for further evaluation of adjudication procedures and reporting standards.openBenelli, Enrico; De Carlo, Alessandro; Biffi, Diana; Mcleod, JohnBenelli, Enrico; De Carlo, Alessandro; Biffi, Diana; Mcleod, Joh

Observing and Measuring Government Openness. A conceptual discussion and application to Mexico
Open government has become a goal for countries all over the world, but it remains an elusive concept. Despite innovative methodologies to assess open government policies, action plans, and interventions in different countries, scholarly research and practical decisions are hindered by the lack of a precise concept and an operationalization. In this paper, we make two contributions to this discussion. First, we argue that the discussions about open government would benefit from taking the grammatical structure of the concept seriously (open is an adjective, government a noun). Second, we propose that, in order to be conceptually and practically useful, open government should be observable. We present the methodology, application and results of an effort to observe and measure open government in Mexico, based on a study of 908 government offices in terms of transparency and participation.En los Ășltimos años el gobierno abierto se ha convertido en un objetivo para muchos paĂses alrededor del mundo, sin embargo, continĂșa siendo un concepto elusivo. Si bien se han diseñado metodologĂas innovadoras para evaluar polĂticas, planes de acciĂłn e intervenciones de gobierno abierto en diferentes paĂses, tanto la investigaciĂłn acadĂ©mica como la toma de decisiones prĂĄcticas para promover un gobierno abierto se han visto afectadas por la falta de una definiciĂłn clara, operacionalizable y observable de dicho concepto. En este artĂculo realizamos dos contribuciones. Primero, argumentamos que las discusiones sobre el gobierno abierto se beneficiarĂan de tomar seriamente la estructura gramatical del concepto (âabiertoâ es un adjetivo y âgobiernoâ es un sustantivo). Segundo, proponemos que, para ser Ăștil conceptual y empĂricamente, el gobierno abierto debe ser observable. Presentamos la metodologĂa, las aplicaciones y los resultados de un esfuerzo por observar y medir el gobierno abierto en MĂ©xico, basados en un estudio de 908 oficinas gubernamentales en tĂ©rminos de transparencia y participaciĂł
Home-Based Business: Exploring the Place Attachment of Entrepreneurs
Entrepreneurship is crucial to a vital and thriving economy, even on the neighbourhood level. This fits into current urban planning policy in the Netherlands, which aims at combining housing and economic functions within neighborhoods. Since an increasing number of entrepreneurs start from home, this calls for insight in the combination of work and home. However, there is limited knowledge about the specific role of the dwelling in the decision to start a firm from home and to stay put. This explorative paper focuses on the use of the dwelling as location of a firm, both in the start-up phase and beyond in the firm life course, and its explanations. Our research questions are: what determines the decision to start a firm within the dwelling of the entrepreneur and its duration in time, and how does this relate to the propensity and decision to move? In our empirical analyses a combination of quantitative and qualitative research methods is used. We analyzed data from 130 questionnaires send out in April 2005 to young entrepreneurs who owned a firm in two Dutch urban neighborhoods. These questionnaires were followed by in-depth interviews with 10 entrepreneurs. We have found that most home based businesses did start from home and are strongly tied to the dwelling - and therefore the neighbourhood. Both firms with past growth in number of personnel and firms with growth aspirations do want to move relatively often. With respect to firm relocation and the personal propensity to move, housing characteristics as adapted dwellings, and owner-occupied, single family and large houses are important. With respect to future home-based business, to most firms breaking the work-home combination is not a realistic option. Household characteristics and more specifically the care of small children keeps entrepreneurs home-based. Also entrepreneurs who work almost full-time are relatively strong attached to their home, which may point to an explicit -and maybe also longlasting- choice for home-basedness. Economic policy should therefore foster start-ups within urban neighbourhoods, as many of them seem to be firmly anchored locally by attachment to their home.
