    Runoff on rooted trees

    We introduce an idealised model for overland flow generated by rain falling on a hill-slope. Our prime motivation is to show how the coalescence of runoff streams promotes the total generation of runoff. We show that, for our model, as the rate of rainfall increases in relation to the soil infiltration rate, there is a distinct phase-change. For low rainfall (the subcritical case) only the bottom of the hill-slope contributes to the total overland runoff, while for high rainfall (the supercritical case) the whole slope contributes and the total runoff increases dramatically. We identify the critical point at which the phase-change occurs, and show how it depends on the degree of coalescence. When there is no stream coalescence the critical point occurs when the rainfall rate equals the average infiltration rate, but when we allow coalescence the critical point occurs when the rainfall rate is less than the average infiltration rate, and increasing the amount of coalescence increases the total expected runoff

    Self-Reflections in Organizations: An Outsider Remarks on Looking at Culture and Lore from the Inside

    As apparent from the title of my remarks, I am an outsider to this organization. I teach folklore courses at UCLA, which is one of five institutions in North America offering both the M.A. and Ph.D. degrees in the study of folklore. I have been asked to speak in this session, in part because I give courses on folk art, aesthetics, fieldwork, and organizational culture and symbolism. As an outsider, as a researcher of organizational culture, and as the final speaker in this session, it seems to be my role to suggest a larger framework of study to which this mini-convention relates. That framework is the rapidly growing field that examines symbolic behavior and culture in organizations

    The Future of Law and Neuroscience

    I was asked to speculate about where the field of Law and Neuroscience may be ten years from now. In that spirit (and while recognizing that the future rarely complies with our predictions) I attempt here some extrapolations. I first consider potential advances in the technologies for monitoring and manipulating brain states, the techniques for analyzing brain data, and the efforts to further integrate relevant fields. I then consider potential neurolaw developments relevant to: (1) detecting things law cares about; (2) individualizing developmental states and brain states; (3) evidence-based legal reforms; (4) legal decision-making; and (5) brain-brain interfaces

    Evolutionary Analysis in Law: An Introduction and Application to Child Abuse

    For contemporary biologists, behavior - like physical form - evolves. Although evolutionary processes do not dictate behavior in any inflexible sense, they nonetheless contribute significantly to the prevalence of various behavioral predispositions that, in turn, tend to yield observable patterns of behavior within every known species. This Article explores the implications for law of evolved behavioral predispositions in humans, urging both caution and optimism. Part I of the Article provides A Primer in Law-Relevant Evolutionary Biology, assuming no prior knowledge in the subject. Part II coins the term evolutionary analysis in law and proposes a model for conducting it. That part demonstrates how legal thinkers can locate, assess, and use knowledge about evolutionary influences on human behavior to further the pursuit of many existing social and legal goals. The Article illustrates the operation of that method by showing how it could aid ongoing efforts to understand and curb child abuse. Throughout, the emphasis is on how the evolutionary perspective on human behavior will typically and usefully supplement, rather than supplant, prevailing notions of the many influences on behavior and the complex interactions among them
