Molecular, morphological and acoustic identification of Eumops maurus and Eumops hansae (Chiroptera: Molossidae) with new reports from Central Amazonia
Eumops maurus and Eumops hansae are rarely captured Neotropical molossid bats for
which information on taxonomy, natural history, and spatial distribution are scarce.
This translates into a poor understanding of their ecology and limits the delimitation
of useful characters for their identification. Here, we describe records of these two
molossids from the Central Brazilian Amazon, providing data on their external and
craniodental morphology, DNA barcode (COI) sequences complemented by acoustic
data for the species. Morphological characters, DNA sequence data and phylogenetic
relationships within the genus Eumops were consistent with those previously described
for both species. Echolocation call characteristics did not differ significantly so as to be
useful for separating E. maurus and E. hansae from other congeners. Our records are,
respectively the first and the second for Central Amazonia as one individual previously
attributed to Eumops amazonicus from Manaus may be considered a junior synonym
for E. hansae. These new records increase the extent of the species’ known ranges,
partially filling in previous existing gaps in their distribution in central South America.
Our data further suggest that these molossid bats forage in a wider range of habitats
than previously thought

Thermal WIMPs and the scale of new physics: global fits of Dirac dark matter effective field theories
We assess the status of a wide class of WIMP dark matter (DM) models in light
of the latest experimental results using the global fitting framework
. We perform a global analysis of effective field theory (EFT)
operators describing the interactions between a gauge-singlet Dirac fermion and
the Standard Model quarks, the gluons and the photon. In this bottom-up
approach, we simultaneously vary the coefficients of 14 such operators up to
dimension 7, along with the DM mass, the scale of new physics and several
nuisance parameters. Our likelihood functions include the latest data from
, direct and indirect detection experiments, and the LHC. For
DM masses below 100 GeV, we find that it is impossible to satisfy all
constraints simultaneously while maintaining EFT validity at LHC energies. For
new physics scales around 1 TeV, our results are influenced by several small
excesses in the LHC data and depend on the prescription that we adopt to ensure
EFT validity. Furthermore, we find large regions of viable parameter space
where the EFT is valid and the relic density can be reproduced, implying that
WIMPs can still account for the DM of the universe while being consistent with
the latest data

Mood and the Market: Can Press Reports of Investors’ Mood Predict Stock Prices?
We examined whether press reports on the collective mood of investors can predict changes in stock prices. We collected data on the use of emotion words in newspaper reports on traders’ affect, coded these emotion words according to their location on an affective circumplex in terms of pleasantness and activation level, and created indices of collective mood for each trading day. Then, by using time series analyses, we examined whether these mood indices, depicting investors’ emotion on a given trading day, could predict the next day’s opening price of the stock market. The strongest findings showed that activated pleasant mood predicted increases in NASDAQ prices, while activated unpleasant mood predicted decreases in NASDAQ prices. We conclude that both valence and activation levels of collective mood are important in predicting trend continuation in stock prices
Remediation programmes for practising doctors to restore patient safety: the RESTORE realist review
Background An underperforming doctor puts patient safety at risk. Remediation is an intervention intended to address underperformance and return a doctor to safe practice. Used in health-care systems all over the world, it has clear implications for both patient safety and doctor retention in the workforce. However, there is limited evidence underpinning remediation programmes, particularly a lack of knowledge as to why and how a remedial intervention may work to change a doctor’s practice. Objectives To (1) conduct a realist review of the literature to ascertain why, how, in what contexts, for whom and to what extent remediation programmes for practising doctors work to restore patient safety; and (2) provide recommendations on tailoring, implementation and design strategies to improve remediation interventions for doctors. Design A realist review of the literature underpinned by the Realist And MEta-narrative Evidence Syntheses: Evolving Standards quality and reporting standards. Data sources Searches of bibliographic databases were conducted in June 2018 using the following databases: EMBASE, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Education Resources Information Center, Database of Abstracts of Reviews of Effects, Applied Social Sciences Index and Abstracts, and Health Management Information Consortium. Grey literature searches were conducted in June 2019 using the following: Google Scholar (Google Inc., Mountain View, CA, USA), OpenGrey, NHS England, North Grey Literature Collection, National Institute for Health and Care Excellence Evidence, Electronic Theses Online Service, Health Systems Evidence and Turning Research into Practice. Further relevant studies were identified via backward citation searching, searching the libraries of the core research team and through a stakeholder group. Review methods Realist review is a theory-orientated and explanatory approach to the synthesis of evidence that seeks to develop programme theories about how an intervention produces its effects. We developed a programme theory of remediation by convening a stakeholder group and undertaking a systematic search of the literature. We included all studies in the English language on the remediation of practising doctors, all study designs, all health-care settings and all outcome measures. We extracted relevant sections of text relating to the programme theory. Extracted data were then synthesised using a realist logic of analysis to identify context–mechanism–outcome configurations. Results A total of 141 records were included. Of the 141 studies included in the review, 64% related to North America and 14% were from the UK. The majority of studies (72%) were published between 2008 and 2018. A total of 33% of articles were commentaries, 30% were research papers, 25% were case studies and 12% were other types of articles. Among the research papers, 64% were quantitative, 19% were literature reviews, 14% were qualitative and 3% were mixed methods. A total of 40% of the articles were about junior doctors/residents, 31% were about practicing physicians, 17% were about a mixture of both (with some including medical students) and 12% were not applicable. A total of 40% of studies focused on remediating all areas of clinical practice, including medical knowledge, clinical skills and professionalism. A total of 27% of studies focused on professionalism only, 19% focused on knowledge and/or clinical skills and 14% did not specify. A total of 32% of studies described a remediation intervention, 16% outlined strategies for designing remediation programmes, 11% outlined remediation models and 41% were not applicable. Twenty-nine context–mechanism–outcome configurations were identified. Remediation programmes work when they develop doctors’ insight and motivation, and reinforce behaviour change. Strategies such as providing safe spaces, using advocacy to develop trust in the remediation process and carefully framing feedback create contexts in which psychological safety and professional dissonance lead to the development of insight. Involving the remediating doctor in remediation planning can provide a perceived sense of control in the process and this, alongside correcting causal attribution, goal-setting, destigmatising remediation and clarity of consequences, helps motivate doctors to change. Sustained change may be facilitated by practising new behaviours and skills and through guided reflection. Limitations Limitations were the low quality of included literature and limited number of UK-based studies. Future work Future work should use the recommendations to optimise the delivery of existing remediation programmes for doctors in the NHS.
