A Research Note: Race, Slavery, and the Ambiguity of Corporate Consciousness

In 1769, as he languished in Córdoba\u27s prison, Diego Antonio Macute seethed. He was not alone. Fifteen of his compatriots shared his sentiments as they confronted their re-enslavement. Recent events painfully reminded them that racial consciousness had limits: their maroon allies, after all, had returned them to their former masters

“Sons of Adam”: Text, Context, and the Early Modern African Subject

Seeking to dislodge the prism that a singular political practice—represented as the story from savage to slave—informed the slave trade, this essay points to a distinct genealogy shaping the earliest encounters between Europeans and Africans

Surface scattering velocities in III-nitride quantum well laser structures via the emission of hybrid phonons

We have theoretically and numerically studied nitride-based quantum well (QW) laser structures. More specifically, we have used a QW made with III-nitride where the width of the barrier region is large relative to the electron mean free path, and we have calculated the electron surface capture velocities by considering an electron flux which is captured into the well region. The process is assisted by the emission of the longitudinal optical phonons as predicted by the hybrid (HB) model. The results of surface capture velocities via the emission of HB phonons are compared to the emission of the dielectric continuum phonons (Zakhleniuk et al 1999 Phys. Status Solidi a 176 79). Our investigation shows that the two different phonon models predict almost the same results for the non-retarded limit. Furthermore, the surface capture velocities strongly depend on the size of the structure and the heterostructure materials. Lastly, a comparison to the recent experimental values shows that our model could accurately describe the experimentally measured parameters of the quantum capture processes

Media Ecology and the Politics of Dissent: Representations of the Hong Kong Protests in the Guardian and China Daily.

The phenomenon of protests, currently on the rise in worldwide democracies, is made known to citizens mainly through representations in the media. This paper, responding to the need for a broader view of protest media coverage in an international context, examines the ways the 2014 Hong Kong protests were covered by the online versions of two highly influential and appealing newspapers, belonging to contrasting media systems: Guardian and China Daily. By revising a typology of previously used frames and inventing new ones this study conducts a quantitative content analysis of news articles with the view to a) highlight similarities and differences in the media coverage of protests within the above - mentioned media systems, b) find out whether the media coverage of such events with political ramifications is affected by the geopolitical interests of the countries. Based on our analysis, this study suggests the need for revising the protest paradigm as important factors - the protests’ momentum, the media systems, the new information communication technologies and certain geopolitical interests - are involved in the dynamics surrounding media coverage of protests and as such they greatly influence the framing process. Moreover, our findings demonstrated that the media coverage of the 2014 HK protests by the two newspapers was reflective of both the media systems in which they function as well as of the distinctive national standpoints

Continuous-variable optical quantum state tomography

This review covers latest developments in continuous-variable quantum-state tomography of optical fields and photons, placing a special accent on its practical aspects and applications in quantum information technology. Optical homodyne tomography is reviewed as a method of reconstructing the state of light in a given optical mode. A range of relevant practical topics are discussed, such as state-reconstruction algorithms (with emphasis on the maximum-likelihood technique), the technology of time-domain homodyne detection, mode matching issues, and engineering of complex quantum states of light. The paper also surveys quantum-state tomography for the transverse spatial state (spatial mode) of the field in the special case of fields containing precisely one photon.Comment: Finally, a revision!

Comparing international coverage of 9/11 : towards an interdisciplinary explanation of the construction of news

This article presents an interdisciplinary model attempting to explain how news is constructed by relying on the contributions of different fields of study: News Sociology, Political Communications, International Communications, International Relations. It is a first step towards developing a holistic theoretical approach to what shapes the news, which bridges current micro to macro approaches. More precisely the model explains news variation across different media organization and countries by focusing on the different way the sense of newsworthiness of journalists is affected by three main variables: national interest, national journalistic culture, and editorial policy of each media organization. The model is developed on the basis of an investigation into what shaped the media coverage of 9/11 in eight elite newspapers across the US, France, Italy and Pakistan
