    Development of theoretically sound methods and strategies for informed science and innovation policy analysis is critically important to each nation's ability to benefit from R&D investments. Gaining deeper insight into complex social processes that influence the growth and formation of scientific fields and development over time of a diverse workforce requires a systemic and holistic view. A research agenda for the development of rigorous complex adaptive systems models is examined to facilitate the study of incentives, strategies, mobility, and stability of the science-based innovation ecosystem, while examining implications for the sustainability of a diverse science enterprise.Agent-Based Model, Complexity, Innovation, Science Studies, Diversity

    Serendipity and Grounded Theory: a Possible Dialogue in Hawthorneā€™s Scenario

    Get PDF
    The purpose of this essay is to present a brief discussion on the emergence of the Human Relations Theory as serendipity or grounded theory. For the theoretical framework, I present topics about serendipity and grounded theory, on theory and substantive theory, followed by the core of the essay, a discussion of the studies taken place at Western Electric Company's Hawthorne Works in Chicago, which gave rise to the focus on human relations. One can conclude that social factors that emerged in Hawthorneā€™s scenario were not being sought out; they were serendipitous discoveries, based on data, as recommended by grounded theory

    Discovery Is Never By Chance: Designing for (Un)Serendipity

    No full text
    Serendipity has a long tradition in the history of science as having played a key role in many significant discoveries. Computer scientists, valuing the role of serendipity in discovery, have attempted to design systems that encourage serendipity. However, that research has focused primarily on only one aspect of serendipity: that of chance encounters. In reality, for serendipity to be valuable chance encounters must be synthesized into insight. In this paper we show, through a formal consideration of serendipity and analysis of how various systems have seized on attributes of interpreting serendipity, that there is a richer space for design to support serendipitous creativity, innovation and discovery than has been tapped to date. We discuss how ideas might be encoded to be shared or discovered by ā€˜association-huntingā€™ agents. We propose considering not only the inventorā€™s role in perceiving serendipity, but also how that inventorā€™s perception may be enhanced to increase the opportunity for serendipity. We explore the role of environment and how we can better enable serendipitous discoveries to find a home more readily and immediately

    You Cannot Have Your Cake and Eat It, too: How Induced Goal Conflicts Affect Complex Problem Solving

    Managing multiple and conflicting goals is a demand typical to both everyday life and complex coordination tasks. Two experiments (N = 111) investigated how goal conflicts affect motivation and cognition in a complex problem- solving paradigm. In Experiment 1, participants dealt with a game-like computer simulation involving a predefined goal relation: Parallel goals were independent, mutually facilitating, or interfering with one another. As expected, goal conflicts entailed lowered motivation and wellbeing. Participantsā€™ understanding of causal effects within the simulation was im- paired, too. Behavioral measures of subjectsā€™ interventions support the idea of adaptive, self-regulatory processes: reduced action with growing awareness of the goal conflict and balanced goal pursuit. Experiment 2 endorses the hypotheses of motivation loss and reduced acquisition of system-related knowledge in an extended problem-solving paradigm of four conflicting goals. Impairing effects of goal interference on motivation and wellbeing were found, although less distinct and robust as in Experiment 1. Participants undertook fewer interventions in case of a goal conflict and acquired less knowledge about the system. Formal complexity due to the interconnectedness among goals is discussed as a limiting influence on inferring the problem structure

    From cosmic ray physics to cosmic ray astronomy: Bruno Rossi and the opening of new windows on the universe

    Full text link
    Bruno Rossi is considered one of the fathers of modern physics, being also a pioneer in virtually every aspect of what is today called high-energy astrophysics. At the beginning of 1930s he was the pioneer of cosmic ray research in Italy, and, as one of the leading actors in the study of the nature and behavior of the cosmic radiation, he witnessed the birth of particle physics and was one of the main investigators in this fields for many years. While cosmic ray physics moved more and more towards astrophysics, Rossi continued to be one of the inspirers of this line of research. When outer space became a reality, he did not hesitate to leap into this new scientific dimension. Rossi's intuition on the importance of exploiting new technological windows to look at the universe with new eyes, is a fundamental key to understand the profound unity which guided his scientific research path up to its culminating moments at the beginning of 1960s, when his group at MIT performed the first in situ measurements of the density, speed and direction of the solar wind at the boundary of Earth's magnetosphere, and when he promoted the search for extra-solar sources of X rays. A visionary idea which eventually led to the breakthrough experiment which discovered Scorpius X-1 in 1962, and inaugurated X-ray astronomy.Comment: This work was presented at the conference "100 Years Cosmic Ray Physics - Anniversary of the V.F. Hess Discovery", 6-8 August, Bad Saarow/Pieskow, Germany, where Hess landed on August 7, 1912, after discovery of the "H\"ohenstrahlung". To be published in the Astroparticle Journa
