    Museums and Heritage Collections in the Cultural Economy : The Challenge of Addressing Wider Audiences and Local Communities

    Although more museums are opening now than at any time in the past, too little attention has been paid to the concrete ways in which cultural processes of commoditisation affect heritage production. How can collections speak to wider audiences as well as to local communities in ways that are economically sustainable? This is not a question that invites simple solutions. Turning to ethnographic fieldwork and interviews, this article focuses on The Nordic Heritage Museum in Seattle and Skokloster Castle near Stockholm to explore how these institutions negotiate public participation, engage new audiences, and adapt their operations to meet the demands of the cultural economy they operate in. Drawing on critical cultural theory, the article highlights how different cultural and economic contexts affect museums’ potential to develop, expand, and meet their objectives. The study explains how two particular museums struggle to open their collections to broader publics, which can be understood as part of a wider process of democratisation

    Activity-Dependent β-Adrenergic Modulation of Low Frequency Stimulation Induced LTP in the Hippocampal CA1 Region

    Abstractβ-Adrenergic receptor activation has a central role in the enhancement of memory formation that occurs during heightened states of emotional arousal. Although β-adrenergic receptor activation may enhance memory formation by modulating long-term potentiation (LTP), a candidate synaptic mechanism involved in memory formation, the cellular basis of this modulation is not fully understood. Here, we report that, in the CA1 region of the hippocampus, β-adrenergic receptor activation selectively enables the induction of LTP during long trains of 5 Hz synaptic stimulation. Protein phosphatase inhibitors mimic the effects of β-adrenergic receptor activation on 5 Hz stimulation–induced LTP, suggesting that activation of noradrenergic systems during emotional arousal may enhance memory formation by inhibiting protein phosphatases that normally oppose the induction of LTP

    The Transparency of the Universe Limited by Ly-alpha Clouds

    The brightnesses of supernovae are commonly understood to indicate that cosmological expansion is accelerating due to dark energy. However the entire discussion presumes a perfectly transparent universe because no effects of reddening associated with the interstellar extinction law are seen. We note that with two kinds of dark matter (baryonic and non-baryonic) strongly dominating the known mass of the universe, it is seriously premature to assume that these dark matter components have not reduced the transmission of the universe for cosmological sources. We show that the long-known LymanαLyman-\alpha clouds, if nucleated by the population of baryonic dark matter primordial planetoids indicated by quasar microlensing, would act as spherical lenses and achromatically fade cosmologically distant sources. We attempt to estimate the amount of this cosmological fading, but ultimately the calculation is limited by lack of a satisfactory model for the tenuous outer parts of a primordial planetoid. We also consider the effects of such cosmological fading on the light of quasars.Comment: 8-Page article submitted to Astronomical Jouna
