    The law of trade secrets is often conceptualized in bilateral terms, as creating and enforcing rights between trade secret owners, on the one hand, and misappropriators on the other hand. This paper, a chapter in a forthcoming collection on the law of trade secrets, argues that trade secrets and the law that guards them can serve structural and institutional roles as well. Somewhat surprisingly, given the law’s focus on secrecy, among the institutional products of trade secrets law are commons, or managed openness: environments designed to facilitate the structured sharing of information. The paper illustrates with examples drawn from existing literature on cuisine, magic, and Internet search.

    Constructing commons in the cultural environment

    This Article sets out a framework for investigating sharing and resource-pooling arrangements for information- and knowledge-based works. We argue that adapting the approach pioneered by Elinor Ostrom and her collaborators to commons arrangements in the natural environment provides a template for examining the construction of commons in the cultural environment. The approach promises to lead to a better understanding of how participants in commons and pooling arrangements structure their interactions in relation to the environments in which they are embedded, in relation to information and knowledge resources that they produce and use, and in relation to one another

    Notes on a Geography of knowledge

    Law and knowledge jointly occupy a metaphorical landscape. Understanding that landscape is essential to understanding the full complexity of knowledge law. This Article identifies some landmarks in that landscape, which it identifies as forms of legal practice: several recent cases involving intellectual property licenses, including the recent patent law decision in Quanta v. LG Electronics and the open source licensing decision in Jacobsen v. Katzer. The Article offers a preliminary framework for exploring the territories of knowledge practice in which those legal landmarks appear

    Creativity and craft

    I revisit the distinction between intangible works of authorship and tangible objects, which is a fundamental proposition of modern copyright law. I suggest that reconsidering that distinction, at least in part, may expand the range of possibilities for aligning modern copyright as an economic construct with the historical roots of copyright and with ethical claims about authorial expression. Revisiting that distinction also may provide contemporary lawyers and policymakers with a much-needed tool for managing challenges posed by digital technology

    Some optimism about fair use and copyright law

    This short paper reflects on the emergence of codes of best practices in fair use, highlighting both the relationship between the best practices approach and an institutional perspective on copyright and the relationship between the best practices approach and social processes of innovation and creativity

    Knowledge curation

    This Article addresses conservation, preservation, and stewardship of knowledge, and laws and institutions in the cultural environment that support those things. Legal and policy questions concerning creativity and innovation usually focus on producing new knowledge and offering access to it. Equivalent attention rarely is paid to questions of old knowledge. To what extent should the law, and particularly intellectual property law, focus on the durability of information and knowledge? To what extent does the law do so already, and to what effect? This article begins to explore those questions. Along the way, the article takes up distinctions among different types of creativity and knowledge, from scholarship and research to commercial entertainment and so-called “User Generated Content”; distinctions among objects, works of authorship, and legal rights accompanying both; distinctions among creations built to last (sometimes called “sustained” works), creations built for speed (including “ephemeral” works), and creations barely built at all (works closely tied to the authorial “self”); and distinctions between analog and digital contexts

    Contrasts in innovation: Pittsburgh then and now

    Assessments of the relationship among law, innovation, and economic growth often begin with one or more propositions of law or law practice and predict how changes might affect innovation or business practice. This approach is problematic when applied to questions of regional economic development, because historic and contemporary local conditions vary considerably. This paper takes a different tack. It takes a snapshot of one recovering post-industrial economy, in Pittsburgh, Pennsylvania, USA. For most of the 20th century, Pittsburgh's steelmakers were leading examples worldwide of American economic prowess. Pittsburgh was so vibrant with industry that a late 19th century travel writer called Pittsburgh hell with the lid taken off, and he meant that as a compliment. In the early 1980s, however, Pittsburgh's steel economy collapsed, a victim of changing worldwide demand for steel and the industry's inflexible commitment to a large-scale integrated production model. As the steel industry collapsed, the Pittsburgh region collapsed, too. Unemployment in some parts of the Pittsburgh region peaked at 20%. More than 100,000 manufacturing jobs disappeared. Tens of thousands of residents moved away annually. Over the last 30 years, Pittsburgh has slowly recovered, building a new economy that balances limited manufacturing with a broad range of high quality services. In 2009, President Barack Obama took note of the region's rebirth by selecting the city to host a summit of the Group of 20 (G-20) finance ministers. The paper describes the characteristics of Pittsburgh today and measures the state of its renewal. It considers the extent, if any, to which law and the legal system have contributed to Pittsburgh's modern success, and it identifies lessons that this Pittsburgh case study might offer for other recovering and transitioning post-industrial regions

    Persistent fluctuations in stride intervals under fractal auditory stimulation

The latter phenomenon is of particular interest because auditory cueing is generally considered to reduce stride variability and may hence be beneficial for stabilizing gait. Complex systems tend to match their correlation structure when synchronizing. In gait training, can one capitalize on this tendency by using a fractal metronome rather than an isochronous one? We examined whether auditory cues with fractal variations in inter-beat intervals yield similar fractal inter-stride interval variability as isochronous auditory cueing in two complementary experiments. In Experiment 1, participants walked on a treadmill while being paced by either an isochronous or a fractal metronome with different variation strengths between beats in order to test whether participants managed to synchronize with a fractal metronome and to determine the necessary amount of variability for participants to switch from anti-persistent to persistent inter-stride intervals. Participants did synchronize with the metronome despite its fractal randomness. The corresponding coefficient of variation of inter-beat intervals was fixed in Experiment 2, in which participants walked on a treadmill while being paced by non-isochronous metronomes with different scaling exponents. As expected, inter-stride intervals showed persistent correlations similar to self-paced walking only when cueing contained persistent correlations. Our results open up a new window to optimize rhythmic auditory cueing for gait stabilization by integrating fractal fluctuations in the inter-beat intervals.Commission of the European Community and the Netherlands Organisation for Scientific Research

    Spontaneous vortices in the formation of Bose-Einstein condensates

    Phase transitions are ubiquitous in nature, ranging from protein folding and denaturisation, to the superconductor-insulator quantum phase transition, to the decoupling of forces in the early universe. Remarkably, phase transitions can be arranged into universality classes, where systems having unrelated microscopic physics exhibit identical scaling behaviour near the critical point. Here we present an experimental and theoretical study of the Bose-Einstein condensation phase transition of an atomic gas, focusing on one prominent universal element of phase transition dynamics: the spontaneous formation of topological defects during a quench through the transition. While the microscopic dynamics of defect formation in phase transitions are generally difficult to investigate, particularly for superfluid phase transitions, Bose-Einstein condensates (BECs) offer unique experimental and theoretical opportunities for probing such details. Although spontaneously formed vortices in the condensation transition have been previously predicted to occur, our results encompass the first experimental observations and statistical characterisation of spontaneous vortex formation in the condensation transition. Using microscopic theories that incorporate atomic interactions and quantum and thermal fluctuations of a finite-temperature Bose gas, we simulate condensation and observe vortex formation in close quantitative agreement with our experimental results. Our studies provide further understanding of the development of coherence in superfluids, and may allow for direct investigation of universal phase-transition dynamics.Comment: 14 pages, 6 figures.
