All work and no pay: consequences of unpaid work experience in the creative industries
This research note evaluates the benefits and pitfalls of unpaid work as an entry route into employment in the creative industries and investigates the consequences of this practice for those who already work in the sector. Based on a qualitative study of perspectives of stakeholders in unpaid work, this article argues that the social capital thesis, often used as a rationale for unpaid work, inadequately explains the practice of unpaid work experience, primarily because it does not take cognisance of the consequences of this practice for other people working in the sector. The study also highlights methodological issues that need to be considered in the future. As well as the importance of a plurality of stakeholder perspectives, the study emphasizes the need to consider the perspectives of those who are excluded from unpaid work and those who are potentially displaced by it
Dilepton distributions at backward rapidities
The dilepton production at backward rapidities in and collisions
at RHIC and LHC energies is investigated in the dipole approach. The results
are shown through the nuclear modification ratio considering
transverse momentum and rapidity spectra. The dilepton modification ratio
presents interesting behavior at the backward rapidities when compared with the
already known forward ones, since it is related with the large kinematical
region that is being probed. The rapidity dependence of the nuclear
modification ratio in the dilepton production is strongly dependent on the
Bjorken behavior of the nuclear structure function ratio
. The transverse momentum dependence at
backward rapidities is modified due to the large nuclear effects: at RHIC
energies, for instance, the ratio is reduced as increases,
presenting an opposite behavior when compared with the forward one. It implies
that the dilepton production at backward rapidities should carry information of
the nuclear effects at large Bjorken , as well as that it is useful to
investigate the dependence of the observables in this kinematical regime.Comment: 15 pages, 6 figures. Version published in the Phys. Rev.
Optical followup of galaxy clusters detected by the South Pole Telescope
The South Pole Telescope (SPT) is a 10 meter telescope operating at mm
wavelengths. It has recently completed a three-band survey covering 2500 sq.
degrees. One of the survey's main goals is to detect galaxy clusters using
Sunyaev-Zeldovich effect and use these clusters for a variety of cosmological
and astrophysical studies such as the dark energy equation of state, the
primordial non-gaussianity and the evolution of galaxy populations. Since 2005,
we have been engaged in a comprehensive optical and near-infrared followup
program (at wavelengths between 0.4 and 5 {\mu}m) to image high-significance
SPT clusters, to measure their photometric redshifts, and to estimate the
contamination rate of the candidate lists. These clusters are then used for
various cosmological and astrophysical studies.Comment: For TAUP 2011 proceeding

An alternative pathway for membrane protein biogenesis at the endoplasmic reticulum.
From Europe PMC via Jisc Publications RouterHistory: epub 2021-07-01, ppub 2021-07-01Publication status: PublishedFunder: Ball State University (Ball State); Grant(s): Provost Startup AwardFunder: Wellcome Trust; Grant(s): 204957/Z/16/ZFunder: NIGMS NIH HHS; Grant(s): R15 GM116032The heterotrimeric Sec61 complex is a major site for the biogenesis of transmembrane proteins (TMPs), accepting nascent TMP precursors that are targeted to the endoplasmic reticulum (ER) by the signal recognition particle (SRP). Unlike most single-spanning membrane proteins, the integration of type III TMPs is completely resistant to small molecule inhibitors of the Sec61 translocon. Using siRNA-mediated depletion of specific ER components, in combination with the potent Sec61 inhibitor ipomoeassin F (Ipom-F), we show that type III TMPs utilise a distinct pathway for membrane integration at the ER. Hence, following SRP-mediated delivery to the ER, type III TMPs can uniquely access the membrane insertase activity of the ER membrane complex (EMC) via a mechanism that is facilitated by the Sec61 translocon. This alternative EMC-mediated insertion pathway allows type III TMPs to bypass the Ipom-F-mediated blockade of membrane integration that is seen with obligate Sec61 clients
