X-Ray, FUV, and UV Observations of alpha Centauri B: Determination of Long-term Magnetic Activity Cycle and Rotation Period
We have been carrying out a study of stellar magnetic activity, dynamos,
atmospheric physics, and spectral irradiances from a sample of solar-type G0-5
V stars with different ages. One of the major goals of this program is to study
the evolution of the Sun's X-ray through NUV spectral irradiances with age. Of
particular interest is the determination of the young Sun's elevated levels of
high-energy fluxes because of the critical roles that X-ray through FUV
emissions play on the photochemical and photoionization evolution of early,
young planetary atmospheres and ionospheres. Motivated by the current
exoplanetary search missions that are hunting for earth-size planets in the
habitable zones of nearby main-sequence G-M stars, we are expanding our program
to cooler, less luminous, but much more numerous main-sequence K-type stars,
such as alpha Centauri B. The long life (2-3x longer than our Sun) and slow
evolution of K stars provide nearly constant energy sources for possible hosted
planets. Presented here are X-ray, UV, and recently acquired FUV observations
of the K1 V star alpha Cen B. These combined high-energy measures provide a
more complete look into the nature of alpha Cen B's magnetic activity and X-UV
radiances. We find that alpha Cen B has exhibited significant long-term
variability in X-ray through NUV emission fluxes, indicating a solar-like
long-term activity cycle of P_cycle = 8.84 years. In addition, analysis of the
short-term rotational modulation of mean light due to the effects of
magnetically active regions has yielded a well-determined rotation period of
P_rotation = 36.2 days. alpha Cen B is the only old main-sequence K star with a
reliably determined age and rotation period, and for early K-stars, is an
important calibrator for stellar age/rotation/activity relations
Living Under Coronavirus and Injecting Drugs in Bristol (LUCID-B): a qualitative study of experiences of COVID-19 among people who inject drugs
BACKGROUND: : People who inject drugs (PWID) are a high-risk group for COVID-19 transmission and serious health consequences. Restrictions imposed in the UK in response to the pandemic led to rapid health and housing service alterations. We aimed to examine PWID experiences of: 1) challenges relating to the COVID-19 public health measures; 2) changes to opioid substitution therapy (OST) and harm reduction services; and 3) perceived effects of COVID-19 on drug use patterns and risk behaviour. METHODS: : Telephone semi-structured interviews were conducted with 28 PWID in Bristol, Southwest of England. Analysis followed a reflexive thematic analysis. RESULTS: : Concern about COVID-19 and adherence to public health guidance varied. Efforts made by services to continue providing support during the pandemic were appreciated and some changes were preferred, such as less frequent OST collection, relaxation of supervised consumption and needle and syringe programmes (NSP) home delivery. However, remote forms of contact were highlighted as less beneficial and more difficult to engage with than in-person contact. Public health guidance advising people to ‘stay home’ led to increased isolation, boredom, and time to ruminate which impacted negatively on mental health. Lockdown restrictions directly impacted on sources of income and routine. Changes in drug use were explained as a consequence of isolation and fewer interactions with peers, problems accessing drugs, reduced drug purity and reduced financial resources. CONCLUSION: : This study captures the significant impacts and challenges of the COVID-19 pandemic on the lives of PWID. While rapid adaptations to service delivery to help mitigate the risks of COVID-19 were appreciated and some changes such as relaxation of supervised daily OST consumption were viewed positively, barriers to access need further attention. Going forwards there may be opportunities to harness the positive aspects of some changes to services

Simplified Models for LHC New Physics Searches
This document proposes a collection of simplified models relevant to the
design of new-physics searches at the LHC and the characterization of their
results. Both ATLAS and CMS have already presented some results in terms of
simplified models, and we encourage them to continue and expand this effort,
which supplements both signature-based results and benchmark model
interpretations. A simplified model is defined by an effective Lagrangian
describing the interactions of a small number of new particles. Simplified
models can equally well be described by a small number of masses and
cross-sections. These parameters are directly related to collider physics
observables, making simplified models a particularly effective framework for
evaluating searches and a useful starting point for characterizing positive
signals of new physics. This document serves as an official summary of the
results from the "Topologies for Early LHC Searches" workshop, held at SLAC in
September of 2010, the purpose of which was to develop a set of representative
models that can be used to cover all relevant phase space in experimental
searches. Particular emphasis is placed on searches relevant for the first
~50-500 pb-1 of data and those motivated by supersymmetric models. This note
largely summarizes material posted at http://lhcnewphysics.org/, which includes
simplified model definitions, Monte Carlo material, and supporting contacts
within the theory community. We also comment on future developments that may be
useful as more data is gathered and analyzed by the experiments.Comment: 40 pages, 2 figures. This document is the official summary of results
from "Topologies for Early LHC Searches" workshop (SLAC, September 2010).

Discourse and religion in educational practice
Despite the existence of long-held binaries between secular and sacred, private and public spaces, school and religious literacies in many contemporary societies, the significance of religion and its relationship to education and society more broadly has become increasingly topical. Yet, it is only recently that the investigation of the nexus of discourse and religion in educational practice has started to receive some scholarly attention. In this chapter, religion is understood as a cultural practice, historically situated and embedded in specific local and global contexts. This view of religion stresses the social alongside the subjective or experiential dimensions. It explores how through active participation and apprenticeship in culturally appropriate practices and behaviors often mediated intergenerationally and the mobilisation of linguistic and other semiotic resources but also affective, social and material resources, membership in religious communities is constructed and affirmed. The chapter reviews research strands that have explored different aspects of discourse and religion in educational practice as a growing interdisciplinary field. Research strands have examined the place and purpose of religion in general and evangelical Christianity in particular in English Language Teaching (ELT) programmes and the interplay of religion and teaching and learning in a wide range of religious and increasingly secular educational contexts. They provide useful insights for scholars of discourse studies to issues of identity, socialisation, pedagogy and language policy
