Zeeman Slowers for Strontium based on Permanent Magnets

We present the design, construction, and characterisation of longitudinal- and transverse-field Zeeman slowers, based on arrays of permanent magnets, for slowing thermal beams of atomic Sr. The slowers are optimised for operation with deceleration related to the local laser intensity (by the parameter $\epsilon$), which uses more effectively the available laser power, in contrast to the usual constant deceleration mode. Slowing efficiencies of up to $\approx$ $18$ $$ are realised and compared to those predicted by modelling. We highlight the transverse-field slower, which is compact, highly tunable, light-weight, and requires no electrical power, as a simple solution to slowing Sr, well-suited to spaceborne application. For $^{88}$Sr we achieve a slow-atom flux of around $6\times 10^9$ atoms$\,$s$^{-1}$ at $30$ ms$^{-1}$, loading approximately $5\times 10^8$ atoms in to a magneto-optical-trap (MOT), and capture all isotopes in approximate relative natural abundances

Principal Roles, Work Demands, and Supports Needed to Implement New Teacher Evaluation

Policy makers at the federal level have embraced an educator effectiveness agenda, which in turn has driven many states across the country to rapidly develop and implement new and more complex teacher evaluation systems. It is increasingly clear that the success of these nascent teacher evaluation systems partly depends on the will, skill, and capacity of school principals, individuals who have historically been tasked with evaluating teachers. School principals have traditionally had, and will in most cases continue to have, primary responsibility for evaluating the 3.7 million public school teachers nationwide. While teacher evaluation innovations present several opportunities for improving instructional supervision and teacher quality, they also involve several challenges, especially on the part of principals. Time demands and cognitive challenges will be inevitable as principals learn about and implement new teacher evaluation systems. Simultaneously, other educational changes going to scale, including Common Core State Standards with aligned assessments and state school accountability systems, will compete for the attention of school leaders and teachers. Negotiating these changes to maximize the positive potential of evaluation reforms requires a commitment by states and districts to resources for training and support as well as policy coherence

Surf Therapy: A Scoping Review of the Qualitative and Quantitative Research Evidence

Over the past 15 years, surf therapy has emerged as a growing therapeutic intervention in diverse communities around the world.  Although the programs operate on the premise that surf therapy provides a range of benefits for both physical and psychological health, there is limited research evidence available to support these claims. There additionally remains a need to further develop evidence-based practices around surf therapy that support the global impact of existing and future surf therapy interventions. This research provides a scoping review of academic literature focused on surf therapy.  The objectives of the research are; (1) to gain a better understanding of the global use of surf therapy and its physical, psychological and social benefits, (2) to identify intervention and research gaps related to surf therapy, (3) to provide recommendations for future surf therapy research, (4) to use the evidence to inform best practices in the field. A systematic article search of the meta-databases Google Scholar, EbscoHost, and Wiley yielded 18 studies that met the inclusion criteria. An additional search for Master’s Theses, Doctoral Dissertations, and expert search yielded 11 studies.  A total of 29 studies were found to meet criteria.  The data from the studies were analyzed using metasynthesis.  As a result, the review provides an overview of the current scientific evidence related to surf therapy, including its physical, psychological, and social benefits.  It additionally provides a detailed description of existing research methods and measures used to evaluate the impact of surfing as a therapeutic intervention that could inform further research designs. The study supports surf therapy as a means of improving both physical and psychosocial health outcomes and includes recommendations for improving surf therapy research and practice

Alcohol‐Associated Liver Disease Before and After COVID‐19 – An Overview and Call for Ongoing Investigation

The Coronavirus Disease-2019 (COVID-19) pandemic has exacted a heavy toll on patients with alcohol-associated liver disease (ALD) and alcohol use disorder (AUD). The collective burden of ALD and AUD was large and growing prior to the COVID-19 pandemic. There is accumulating evidence that this pandemic has had a large direct effect on these patients and is likely to produce indirect effects via delays in care, psychological strain, and increased alcohol use. Now a year into the pandemic, it is important that clinicians fully understand the effects of the COVID-19 pandemic on patients with ALD and AUD. To fill existing gaps in knowledge, the scientific community must set research priorities for patients with ALD regarding their risk of COVID-19, prevention/treatment of COVID-19, changes in alcohol use during the pandemic, best use of AUD treatments in the COVID-19 era, and downstream effects of this pandemic on ALD. Conclusion: The COVID-19 pandemic has already inflicted disproportionate harms on patients with ALD and ongoing, focused research efforts will be critical to better understand the direct and collateral effects of this pandemic on ALD
