    Rapid acceleration of electrons in the magnetosphere by fast-mode MHD waves

    Full text link
    During major megnetic storms, enhanced flux of relativistic electrons in the inner magnetosphere have been observed to correleated with ULF waves. The enhancements can take place over a period of several hours. In order to account for such a rapid generation of relativistic electrons, we examine the mechanism of transit-time acceleration of electrons by low-frequency fast-mode MHD waves, here the assumed form of ULF waves. Calcaulations of the acceleration timescales in the model show that fast-mode waves in the Pc4 to Pc5 frequency range, with typically observed wave amplitudes 10--20 nT, can accelerate the seed electrons to energies of order MeV in a period of a few hours.Comment: 9 pages, 3 figures, Accepted to J.

    Background: Recruiting and retaining medical, nursing, and allied health professionals in rural and remote areas is a worldwide challenge, compromising continuity of care and population health outcomes in these locations. Specifically, pharmacists play an essential and accessible frontline healthcare role, and are often the first point of contact for health concerns. Despite several incentives, there remains a maldistribution and undersupply of pharmacists in rural and remote areas across many parts of the world. Although current systematic reviews have focussed on factors affecting pharmacists’ retention generally, literature specifically focused on rural pharmacist workforce in a global context remains limited. The aim of this systematic review is to identify factors associated with recruitment and retention of the pharmacist workforce in rural and remote settings. Better understanding of these contributors will inform more effective interventional strategies to resolve pharmacist workforce shortages. Methods: A systematic search of primary studies was conducted in online databases, including Medline, Embase, CINAHL, Scopus, Web of Science and PsycINFO, and by hand-searching of reference lists. Eligible studies were identified based on predefined inclusion/exclusion criteria and methodological quality criteria, utilising the Critical Appraisal Skills Programme (CASP) and Good Reporting of A Mixed Methods Study (GRAMMS) checklists. Results: The final review included 13 studies, with quantitative, qualitative, or mixed methods research design. Study-specific factors associated with recruitment and retention of pharmacists in rural practice were identified and grouped into five main themes: geographic and family-related, economic and resources, scope of practice or skills development, the practice environment, and community and practice support factors. Conclusions: The results provide critical insights into the complexities of rural recruitment and retention of pharmacists and confirms the need for flexible yet multifaceted responses to overcoming rural pharmacist workforce challenges. Overall, the results provide an opportunity for rural communities and health services to better identify key strengths and challenges unique to the rural and remote pharmacist workforce that may be augmented to guide more focussed recruitment and retention endeavours. © 2021, The Author(s). **Please note that there are multiple authors for this article therefore only the name of the Federation University Australia affiliates “Daniel Terry, Blake Peck, Danny Hills, Ed Baker and David Schmitz” are provided in this record** Correction to: Factors contributing to the recruitment and retention of rural pharmacist workforce: a systematic review (BMC Health Services Research, (2021), 21, 1, (1052), 10.1186/s12913-021-07072-1

    Objective: To pilot the Pharmacist Community Apgar Questionnaire (PharmCAQ) and evaluate its usability and capacity to develop a greater understanding of the unique factors that impact the rural recruitment and retention of pharmacists. Design: Cross-sectional design involving face-to-face, telephone or video conferencing interviews. Setting: Twelve rural communities across Tasmania and Western Victoria, Australia. Participants: Participants (n = 24) included pharmacists, a Director of Clinical Services, pharmacy practice managers and senior pharmacy assistants. Main Outcome Measures: Interviews enabled the completion of the PharmCAQ, which assigns quantitative values to 50 key factors to ascertain a community\u27s strengths and challenges associated with recruitment and retention and their relative importance to the pharmacist workforce. Results: The cumulative PharmCAQ scores indicated the tool was sensitive enough to differentiate high- and low-performing communities. Overall, the highest-rated factors considered most vital to pharmacist recruitment and retention were the reputation of the pharmacy, the ability of the pharmacist to be independent and autonomous, the loyalty of the community to the pharmacy, the level and stability of monetary compensation and the breadth of tasks available to a pharmacist. Conclusions: This study identified the strengths and challenges of participating communities and provided an insight into the shared factors to consider in recruiting and retaining pharmacists. Further, each community has unique strengths that can further be promoted in recruitment, flagging where limited resources are best used to address site specific challenges. This is more likely to ensure the matching of the right candidate with the right community

    Understanding rural pharmacists’ perspectives: lived experiences and insights associated with rural recruitment and retention

    Introduction: Pharmacists serve an important role in rural communities, and in some cases they may be the only health professional available. Their recruitment and retention is a major concern for rural communities and health services; however, a deeper understanding regarding the advantages and challenges of sustaining a rural pharmacy workforce is somewhat limited. The aim of this study was to develop a deeper understanding of pharmacists' perspectives about factors influencing pharmacist recruitment and retention to rural and remote communities. Methods: The exploratory study, carried out in rural Tasmania and rural Western Victoria, used a qualitative descriptive design. Structured interviews, lasting between 30-60 minutes, were conducted by a single researcher using the Pharmacist Community Apgar Questionnaire via face-to-face, telephone or videoconferencing technology. Data were analysed thematically using verbatim transcription, extraction of significant statements and identification of similarities in formulated meanings, grouping the similar meanings and significant statements that pertained to the phenomena of interest. Specifically, qualitative data were used to provide a deeper understanding of factors identified as key assets, capabilities, or those most challenging for pharmacist recruitment and retention. Results: The advantages and disadvantages rural communities face in recruiting and retaining pharmacists are presented. These insights are linked to the advantages of financial income, incentives and moving allowance. Further advantages include the degree of practice autonomy, breadth of tasks, the perception of the community, loyalty to the pharmacy and its pharmacists, along with community recognition. Challenges associated with the recruitment and retention of pharmacists centred on the need for spousal or partner employment opportunities, having greater proximity to schools, access to social or cultural opportunities, along with good transport connections. Further challenges included housing, the cost of schooling for children, having adequate locum or peer coverage and opportunities to host interns. Discussion: The study provides a deeper exploration of the meaning and experiences of factors that previous research has shown are considered advantageous or challenging to the recruitment and retention of pharmacists in rural areas. Through the voices of pharmacists living and working in a rural area, the findings further enlighten our understanding regarding how the multifaceted and complex nature of health workforce planning may be addressed. As such, greater pharmacist recruitment and retention is enabled through adequate financial compensation and incentives, along with additional tax incentives for business and health services. Further, innovation is required to enhance economic sustainability. Locum coverage and intern opportunities also require innovative approaches to address concerns among potential candidates. Lastly, efforts to enable and support social connections such as schooling and spousal employment, while building community connection and a sense of rural community belonging, remain essential to recruit and retain pharmacists. Conclusion: Rural pharmacist recruitment and retention is complex, requiring a multi-pronged approach to implement practical solutions. Given this complexity and the unique features of each rural community, solutions require whole-of-community ownership to create innovative solutions. Recognition of specific advantages and challenges can address key driving factors for pharmacist recruitment and retention in rural communities

    Generation of ordered protein assemblies using rigid three-body fusion

    Protein nanomaterial design is an emerging discipline with applications in medicine and beyond. A longstanding design approach uses genetic fusion to join protein homo-oligomer subunits via α-helical linkers to form more complex symmetric assemblies, but this method is hampered by linker flexibility and a dearth of geometric solutions. Here, we describe a general computational method that performs rigid three-body fusion of homo-oligomer and spacer building blocks to generate user-defined architectures, while at the same time significantly increasing the number of geometric solutions over typical symmetric fusion. The fusion junctions are then optimized using Rosetta to minimize flexibility. We apply this method to design and test 92 dihedral symmetric protein assemblies from a set of designed homo-dimers and repeat protein building blocks. Experimental validation by native mass spectrometry, small angle X-ray scattering, and negative-stain single-particle electron microscopy confirms the assembly states for 11 designs. Most of these assemblies are constructed from DARPins (designed ankyrin repeat proteins), anchored on one end by α-helical fusion and on the other by a designed homo-dimer interface, and we explored their use for cryo-EM structure determination by incorporating DARPin variants selected to bind targets of interest. Although the target resolution was limited by preferred orientation effects, small scaffold size, and the low-order symmetry of these dihedral scaffolds, we found that the dual anchoring strategy reduced the flexibility of the target-DARPIN complex with respect to the overall assembly, suggesting that multipoint anchoring of binding domains could contribute to cryo-EM structure determination of small proteins

    Pliocene and Pleistocene geologic and climatic evolution in the San Luis Valley of south-central Colorado

    Full text link
    Sediments of the Alamosa Formation spanning the upper part of the Gauss and most of the Matuyama Chrons were recovered by coring in the high (2300 m) San Luis Valley of south-central Colorado. The study site is located at the northern end of the Rio Grande rift. Lithologic changes in the core sediments provide evidence of events leading to integration of the San Luis drainage basin into the Rio Grande. The section, which includes the Huckleberry Ridge Ash (2.02 Ma) and spans the entire Matuyama Chron, contains pollen, and invertebrate and vertebrate fossils. Stable isotope analyses of inorganic and biogenic carbonate taken over most of the core indicate substantially warmer temperatures than occur today in the San Luis Valley. At the end of the Olduvai Subchron, summer precipitation decreased, summer pan evaporation increased, and temperatures increased slightly compared to the earlier climate represented in the core. By the end of the Jaramillo Subchron, however, cold/wet and warm/dry cycles become evident and continue into the cold/wet regime associated with the deep-sea oxygen-isotope Stage 22 glaciation previously determined from outcrops at the same locality. Correspondence between the Hansen Bluff climatic record and the deep-sea oxygen-isotope record (oxygen-isotope stages from about 110-18) is apparent, indicating that climate at Hansen Bluff was responding to global climatic changes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29956/1/0000316.pd

    A great friggin' swindle? Sex Pistols, school kids and 1979

    Get PDF
    This article examines the popularity of the Sex Pistols’ song “Friggin’ in the Riggin’” and its parent album The Great Rock ‘n’ Roll Swindle. It argues that in 1979 the Sex Pistols attracted a new and younger audience, one that has been neglected in previous studies of the band, which tend instead to focus on the years 1976 and 1977 and the band’s original coterie of followers. This article locates the teenage appeal of “Friggin’ in the Riggin’” in its themes of swearing, sex and piracy. It also explores the media infrastructure that enabled young adolescents to access this music. Following on from this, the article charts the triumph of Johnny Rotten’s Sex Pistols’ narrative over that of Malcolm McLaren. The Great Rock ‘n’ Roll Swindle fell prey to notions of authenticity, coherence and the canonical tastes of young adults
