Engineered Migration as a Coercive Instrument: The 1994 Cuban Balseros Crisis

This paper presents a case study of the August 1994 Cuban “balseros”—i.e. rafters—crisis, commonly known as Mariel II, during which over 35,000 Cubans fled the island and headed towards Florida. This paper argues that Castro launched the crisis in an attempt to manipulate the US’s fears of another Mariel boatlift, in order to compel a shift in United States (US) policy, both on immigration and on a wider variety of issues. As the end of the crisis brought with it a radical redefinition of US immigration policy toward Cuba, the paper further contends that from Castro’s perspective, this exercise in coercion proved a qualified success—his third such successful use of the Cuban people as an asymmetric political weapon against the US

Comparison of engagement and emotional responses of older and younger adults interacting with 3D cultural heritage artefacts on personal devices

The availability of advanced software and less expensive hardware allows museums to preserve and share artefacts digitally. As a result, museums are frequently making their collections accessible online as interactive, 3D models. This could lead to the unique situation of viewing the digital artefact before the physical artefact. Experiencing artefacts digitally outside of the museum on personal devices may affect the user's ability to emotionally connect to the artefacts. This study examines how two target populations of young adults (18–21 years) and the elderly (65 years and older) responded to seeing cultural heritage artefacts in three different modalities: augmented reality on a tablet, 3D models on a laptop, and then physical artefacts. Specifically, the time spent, enjoyment, and emotional responses were analysed. Results revealed that regardless of age, the digital modalities were enjoyable and encouraged emotional responses. Seeing the physical artefacts after the digital ones did not lessen their enjoyment or emotions felt. These findings aim to provide an insight into the effectiveness of 3D artefacts viewed on personal devices and artefacts shown outside of the museum for encouraging emotional responses from older and younger people

Obscured GOODS AGN and Their Host Galaxies at z < 1.25: The Slow Black Hole Growth Phase

We compute black hole masses and bolometric luminosities for 87 obscured AGN in the redshift range 0.25 < z < 1.25, selected from the GOODS deep multi-wavelength survey fields via their X-ray emission. We fit the optical images and obtain morphological parameters for the host galaxy, separating the galaxy from its central point source, thereby obtaining a four-band optical SED for each active nucleus. We calculate bolometric luminosities for these AGN by reddening a normalized mean SED of GOODS broad-line AGN to match the observed central point-source SED of each obscured AGN. This estimate of Lbol has a smaller spread than simple bolometric corrections to the X-ray luminosity or direct integration of the observed multi-wavelength SED, suggesting it is a better measure. We estimate central black hole masses from the bulge luminosities. The black hole masses span a wide range, 7 x 10^6 M_sun to 6 x 10^9 M_sun; the median black hole mass is 5 x 10^8 M_sun. The majority of these AGN have L/L_Edd < 0.01, and we detect no significant evolution of the mean Eddington ratio to z = 1.25. This implies that the bulk of black hole growth in these obscured AGN must have occurred at z > 1 and that we are observing these AGN in a slow- or no-growth state.Comment: Accepted to ApJ; 17 pages, 10 figures, 2 tables; Updated version has 1 corrected referenc
