Youâre either with us or against us! Moral conviction determines how the politicized distinguish friend from foe
This is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this recordThree studies investigated how politicized collective identification affects individualsâ reactions towards others. We hypothesized that a strong politicized identity tends to be accompanied by a moral conviction about the politicized cause, which in turn determines how the politicized respond to those less committed to their cause. Consistent with this, Study 1 showed that politicized (feminist) identification is associated with lower identification with women who place moderate (vs. high) moral value on gender equality. Study 2 showed that politicized identification was associated with negative emotions towards people who disagree with this cause and this was mediated by the extent to which participants saw supporting the activist goal as morally obligatory. Study 3 showed that politicized identification, to the extent to which it implied holding a moral conviction about the activist cause, is associated with a desire for more social distance to an attitudinally dissimilar other, but not from an attitudinally similar other.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The research reported in this article was partially funded by a Marie Curie Intra-European Fellowship (328485) awarded to Maarten Zaal

This report provides the results of the seventh underwater television on the âPorcupine Bank Nephrops groundsâ ICES assessment area; Functional Unit 16. The survey was multi-disciplinary in nature collecting UWTV, CTD and other ecosystem data. In total 65 UWTV stations were successfully completed in a randomised 6 nautical mile isometric grid covering the full spatial extent of the stock. The mean burrow density observed in 2019, adjusted for edge effect, was 0.14 burrows/mÂČ. The final krigged abundance estimate was 1010 million burrows with a relative standard error of 5% and an estimated stock area of 7,130 km2. The 2019 abundance estimate was 9.5% lower than in 2018. Using the 2019 estimate of abundance and updated stock data implies catches between 2127 and 2637 tonnes in 2020 that correspond to the F ranges in the EU multi annual plan for Western Waters (assuming that all catch is landed). Four species of sea-pen; Virgularia mirabilis, Funiculina quadrangularis, Pennatula phosphorea and the deepwater sea-pen Kophobelemnon stelliferum were observed during the survey. Trawl marks were also observed on 31% of the stations surveyed
Echo-Mapping of Swift J1753.5-0127
We present two epochs of coordinated X-ray-optical timing observations of the
black hole candidate Swift J1753.5-0127 during its 2005 outburst. The first
epoch in July occurred at outburst peak. Two consecutive nights of observations
using the McDonald Observatory Argos camera with the Rossi X-ray Timing
Explorer show a consistent correlation with an immediate response and an
extended tail lasting ~5s. The properties of the variability and the
correlation are consistent with thermal reprocessing in an accretion disk. The
shortness of the lag suggests a short orbital period consistent with that
recently claimed. The second epoch in August used the VLT FORS2 HIT mode again
in conjunction with RXTE. Again a repeatable correlation is seen between two
independent subsets of the data. In this case, though, the cross-correlation
function has an unusual structure comprising a dip followed by a double-peak.
We suggest that this may be equivalent to the dip plus single peak structure
seen by Kanbach et al. (2001) in XTE J1118+480 and attributed there to
synchrotron emission; a similar structure was seen during later activity of
Swift J1753.5-0127 by Durant et al. (2008).Comment: 7 pages, accepted for publication in Monthly Notices of the Royal

Physical interpretation of gauge invariant perturbations of spherically symmetric space-times
By calculating the Newman-Penrose Weyl tensor components of a perturbed
spherically symmetric space-time with respect to invariantly defined classes of
null tetrads, we give a physical interpretation, in terms of gravitational
radiation, of odd parity gauge invariant metric perturbations. We point out how
these gauge invariants may be used in setting boundary and/or initial
conditions in perturbation theory.Comment: 6 pages. To appear in PR
Age and geochemistry of granitoids in the Precambrian basement of Ăland, SE Sweden â implications for the extension of the Transscandinavian Igneous Belt in the Baltic Sea region
The Precambrian crust in the Baltic
Sea region is mostly covered by Phanerozoic sedimentary rocks but can be
studied in drill cores. Two granitoids from the crystalline basement below
Ăland were collected from the archives of the Geological Survey of Sweden and
analyzed for geochemistry and dated with the U-Pb method on zircons. The Böda
Hamn granitoid (northern Ăland) has a monzodioritic composition and an age of
1799.8±3 Ma while the ValsnĂ€s granitoid (central Ăland) has a quartz monzonitic
composition and an age of 1784.9±5.7 Ma. These geochemical-isotopic
characteristics are compatible with those of generation 1 of the
Transscandinavian Igneous Belt (TIB) in the Fennoscandian Shield, â„30 km west
of Ăland.A more detailed review of the TIB-1
generation shows that two
sub-generations (1a and 1b) can
be distinguished on each respective side of the Oskarshamn-Jönköping Belt
(OJB). Sub-generation 1a (north of OJB) has an age span of 1794-1808 Ma while sub-generation
1b (south of OJB) has an age span of 1769-1793 Ma. According to this subdivision, the Böda Hamn monzodiorite belongs to sub-generation 1a, which also can be followed to southernmost Gotland
(Sundblad et al. 2003) and the ValsnÀs quartz monzonite belongs to sub-generation 1b, which can be followed to
the Latvian/Lithuanian border, where a marginally younger granitoid was
reported from off shore drill core E-7 (Salin et al. 2016). Taken
together, these data suggest that the Transscandinavian Igneous Belt can
be traced across the Baltic Sea from the exposed parts within the Fennoscandian
Shield to the Latvian/Lithuanian border.Salin, E.,

On the existence of dyons and dyonic black holes in Einstein-Yang-Mills theory
We study dyonic soliton and black hole solutions of the
Einstein-Yang-Mills equations in asymptotically anti-de Sitter space. We prove
the existence of non-trivial dyonic soliton and black hole solutions in a
neighbourhood of the trivial solution. For these solutions the magnetic gauge
field function has no zeros and we conjecture that at least some of these
non-trivial solutions will be stable. The global existence proof uses local
existence results and a non-linear perturbation argument based on the (Banach
space) implicit function theorem.Comment: 23 pages, 2 figures. Minor revisions; references adde
Analysis of multiple chromosomal rearrangements in the genome of Willisornis vidua using BAC-FISH and chromosome painting on a supposed conserved karyotype
Background Thamnophilidae birds are the result of a monophyletic radiation of insectivorous Passeriformes. They are a diverse group of 225 species and 45 genera and occur in lowlands and lower montane forests of Neotropics. Despite the large degree of diversity seen in this family, just four species of Thamnophilidae have been karyotyped with a diploid number ranging from 76 to 82 chromosomes. The karyotypic relationships within and between Thamnophilidae and another Passeriformes therefore remain poorly understood. Recent studies have identified the occurrence of intrachromosomal rearrangements in Passeriformes using in silico data and molecular cytogenetic tools. These results demonstrate that intrachromosomal rearrangements are more common in birds than previously thought and are likely to contribute to speciation events. With this in mind, we investigate the apparently conserved karyotype of Willisornis vidua, the Xingu Scale-backed Antbird, using a combination of molecular cytogenetic techniques including chromosome painting with probes derived from Gallus gallus (chicken) and Burhinus oedicnemus (stone curlew), combined with Bacterial Artificial Chromosome (BAC) probes derived from the same species. The goal was to investigate the occurrence of rearrangements in an apparently conserved karyotype in order to understand the evolutionary history and taxonomy of this species. In total, 78 BAC probes from the Gallus gallus and Taeniopygia guttata (the Zebra Finch) BAC libraries were tested, of which 40 were derived from Gallus gallus macrochromosomes 1-8, and 38 from microchromosomes 9-28. Results The karyotype is similar to typical Passeriformes karyotypes, with a diploid number of 2n = 80. Our chromosome painting results show that most of the Gallus gallus chromosomes are conserved, except GGA-1, 2 and 4, with some rearrangements identified among macro- and microchromosomes. BAC mapping revealed many intrachromosomal rearrangements, mainly inversions, when comparing Willisornis vidua karyotype with Gallus gallus, and corroborates the fissions revealed by chromosome painting. Conclusions Willisornis vidua presents multiple chromosomal rearrangements despite having a supposed conservative karyotype, demonstrating that our approach using a combination of FISH tools provides a higher resolution than previously obtained by chromosome painting alone. We also show that populations of Willisornis vidua appear conserved from a cytogenetic perspective, despite significant phylogeographic structure.Peer reviewe

The acquisition of Sign Language: The impact of phonetic complexity on phonology
Research into the effect of phonetic complexity on phonological acquisition has a long history in spoken languages. This paper considers the effect of phonetics on phonological development in a signed language. We report on an experiment in which nonword-repetition methodology was adapted so as to examine in a systematic way how phonetic complexity in two phonological parameters of signed languages â handshape and movement â affects the perception and articulation of signs. Ninety-one Deaf children aged 3â11 acquiring British Sign Language (BSL) and 46 hearing nonsigners aged 6â11 repeated a set of 40 nonsense signs. For Deaf children, repetition accuracy improved with age, correlated with wider BSL abilities, and was lowest for signs that were phonetically complex. Repetition accuracy was correlated with fine motor skills for the youngest children. Despite their lower repetition accuracy, the hearing group were similarly affected by phonetic complexity, suggesting that common visual and motoric factors are at play when processing linguistic information in the visuo-gestural modality
