GRB 050223: A dark GRB in a dusty starburst galaxy
Aims: We aim at detecting and determining the properties of the host galaxy
of the dark GRB 050223.
Methods: We use VLT optical/NIR images coupled to Swift X-ray positioning,
and optical spectra of the host galaxy to measure its properties.
Results: We find a single galaxy within the Swift error box of GRB 050223. It
is located at z = 0.584 and its luminosity is L ~ 0.4 L*. Emission lines in the
galaxy spectrum imply an intrinsic SFR > 7 Msun/yr, and a large extinction A_V
> 2 mag within it. We also detect absorption lines, which reveal an underlying
stellar population with an age between 40 Myr and 1.5 Gyr.
Conclusions: The identification of a host galaxy with atypical properties
using only the X-ray transient suggests that a bias may be present in the
former sample of host galaxies. Dust obscuration together with intrinsic
faintness are the most probable causes for the darkness of this burst.Comment: 4 pages, 2 figures, accepted for publication in Astronomy &

HIV subtype is not associated with dementia among individuals with moderate and advanced immunosuppression in Kampala, Uganda
HIV-associated neurocognitive disorders (HAND) are a common neurological manifestation of HIV infection. A previous study suggested that HIV dementia may be more common among patients with subtype D virus than among those with subtype A virus among HIV+ individuals with advanced immunosuppression. We conducted a study to evaluate the frequency of HIV dementia, and the association of HIV dementia with HIV subtype and compartmentalization among HIV+ individuals with moderate and advanced immunosuppression (CD4 lymphocyte count >150 cells/ÎĽL and < 250 cells/ÎĽL)
Doing Research on Populism
Matthijs Rooduijn argues that the focus on populism has become a self-perpetuating process, with whole research groups, conferences and journals dedicated to the topic. To help the public get a better understanding of populism, Rooduijn and other colleagues collaborated with The Guardian to produce an investigative series of articles on populism, a project that also led to the creation of The PopuList, which, thanks to country experts, categorises European political parties as populist, far right, far left and/or Eurosceptic. Rooduijn then describes the latest developments in the field, the current trends, and the fruitful contaminations between populism research and other fields
Populism and nationalism revisited: A comparative study of the Spanish and Portuguese New Left
Current definitions of populism are insufficiently determinate. They fail to distinguish between populism and nationalism. We propose to remedy this problem by advancing a new definition of populism as the logic of democratic resentment. We apply this new definition to a comparison between Spain’s Podemos and Portugal’s Left Bloc (BE), which we classify as social carriers of populism. We make two contributions to the literature. First, our findings dispute existing characterisations of the Portuguese case, which fail to distinguish between populist and nationalist claim-making. Second, our analysis undermines depictions of Podemos as the consummate populist party in Iberia: in 2015, the little studied BE was a stronger populist carrier than Podemos. The analytical framework underpinning this conclusion offers a more refined approach to populism than the alternatives and sets a higher standard for empirical replication.Research Project “POPULUS – Rethinking Populism” (PDTC/SOC-SOC/28524/2017).

Observations of physical effects from tsunamis of December 30, 2002 at Stromboli volcano
On December 30, 2002, following an intense
period of activity of Stromboli volcano (south Tyrrhenian
Sea, Italy), complex mass failures occurred on the northwest
slope of the mountain which also involved the underwater
portion of the volcanic edifice for a total volume of
about 2–3×107 m3. Two main landslides occurred within
a time separation of 7 min, and both set tsunami waves in
motion that hit the coasts of Stromboli causing injuries to
three people and severe damage to buildings and structures.
The tsunamis also caused damage on the island of Panarea,
some 20 km to the SSE from the source. They were observed
all over the Aeolian archipelago, at the island of
Ustica to the west, along the northern Sicily coasts to the
south as well as along the Tyrrhenian coasts of Calabria to
the east and in Campania to the north. This paper presents
field observations that were made in the days and weeks
immediately following the events. The results of the quantitative
investigations undertaken in the most affected places,
namely along the coasts of Stromboli and on the island of
Panarea, are reported in order to highlight the dynamics
of the attacking waves and their impact on the physical
environment, on the coastal structures and on the coastal
residential zone. In Stromboli, the tsunami waves were
most violent along the northern and northeastern coastal
belt between Punta Frontone and the village of Scari, with
maximum runup heights of about 11 m measured on the
beach of Spiaggia Longa. Measured runups were observed to decay rapidly with distance from the source, typical of
tsunami waves generated by limited-area sources such as
landslides.Published450-461JCR Journalreserve
