The Plunder of Maqdala: Ethical Concerns Around Belongings and Ancestral Remains in Museums

During the colonial period, museums did not just passively benefit from the plunder of human remains and culturally sacred items. When Britain sent a punitive military expedition to Abyssinia (now Ethiopia) in 1863, it was accompanied by Richard Holmes, a staff member of the British Museum, whose purchase of loot from the expeditionary force institutionalised the plunder of cultural heritage. His inclusion in the expeditionary force was carefully planned, though the belongings he took — mainly manuscripts, religious items and emblems of power belonging to the Ethiopian royal family — were not the intended focus of his participation. Whilst the UK’s 2004 Human Tissue Act had a beneficial impact on the treatment of human remains in museums, objects belonging to colonised people are often still positioned as artworks or artefacts, evidencing ignorance of the deep personal and spiritual links that connect them back to their communities of origin. This article draws on our professional experience of curation and research in museums and libraries, as well as the impact of ICOM’s new Museum Definition on our practice. Joint research on the Maqdala expedition led us to question assumptions about the legacy of empire in museums and to scrutinise unexpected connections in the history of museum collections. This article addresses the problematic relationship between collecting and imperial power, the false dichotomy between ‘artefacts’ (belongings) and ‘human remains’ (ancestors) and the need to decolonise collections through further research and the recognition of ongoing cultural and physical violence

I nostri figli, le nostre scuole, il nostro futuro: la scuola del futuro parte dall’Aquila

Policy paper La scuola è luogo di cittadinanza, soprattutto in una città che ha bisogno di cittadini “nuovi”, consapevoli del passato e portatori di futuro. Le nuove generazioni hanno il diritto di formarsi in spazi sicuri e ben organizzati, che consentano lo sviluppo dei migliori processi di apprendimento ed insegnamento, di partecipazione, di socializzazione e di acquisizione di sensibilità, valori da spendere positivamente nella costruzione della città futura

PMD tolerance of 288 Gbit/s Coherent WDM and transmission over unrepeatered 124 km of field-installed single mode optical fiber

Low-cost, high-capacity optical transmission systems are required for metropolitan area networks. Direct-detected multi-carrier systems are attractive candidates, but polarization mode dispersion (PMD) is one of the major impairments that limits their performance. In this paper, we report the first experimental analysis of the PMD tolerance of a 288Gbit/s NRZ-OOK Coherent Wavelength Division Multiplexing system. The results show that this impairment is determined primarily by the subcarrier baud rate. We confirm the robustness of the system to PMD by demonstrating error-free performance over an unrepeatered 124km field-installed single-mode fiber with a negligible penalty of 0.3dB compared to the back-to-back measurements.
