The Maser Monitoring Organisation is a collection of researchers exploring the use of time-variable maser emission in the investigation of astrophysical phenomena. The forward directed aspects of research primarily involve using maser emission as a tool to investigate star formation. Simultaneously, these activities have deepened knowledge of maser emission itself in addition to uncovering previously unknown maser transitions. Thus a feedback loop is created where both the knowledge of astrophysical phenomena and the utilised tools of investigation themselves are iteratively sharpened. The project goals are open-ended and constantly evolving, however, the reliance on radio observatory maser monitoring campaigns persists as the fundamental enabler of research activities within the group.

Recently, remarkable progress has been made in understanding the formation of high mass stars. Observations provided direct evidence that massive young stellar objects (MYSOs), analogously to low-mass ones, form via disk-mediated accretion accompanied by episodic accretion bursts, possibly caused by disk fragmentation. In the case of MYSOs, the mechanism theoretically provides a means to overcome radiation pressure, but in practice it is poorly studied - only three accretion bursts in MYSOs have been caught in action to date. A significant contribution to the development of the theory has been made with the study of masers, which have proven to be a powerful tool for locating “bursting” MYSOs. This overview focuses on the exceptional role that masers play in the search and study of accretion bursts in massive protostars.

Summary
As a minor tragedy foreshadowing a larger one, namely the downfall of Camelot, Malory’s story of Elaine, the Fair Maid of Astolat, has attracted considerable attention not only from students of medieval literature but also from modern poets, painters, and illustrators – the most famous adaptation probably being Tennyson’s “Lady of Shalott.” Scholarly interest, too, has remained unflagging. The story of an astonishingly self-determined young woman, whose role within the narrative Malory considerably enhanced, by comparison with his sources, continues to fascinate and has begun to incite new commentary from feminist and affect-theory-orientated perspectives. Georgiana Donavin and Sue Ellen Holbrook, for instance, have stressed the degree to which the unhappy lover’s portrayal is constructed on the basis of very particular discursive structures, structures rhetorical and affective. The reading presented in this contribution will scrutinize the story from a point of view strongly indebted to their perspectives. Following in Sue Ellen Holbrook’s footsteps, especially, I wish to discuss how an editorial re-interpretation of a single letter (in the sense of “character”) in the Maid of Astolat’s farewell letter (here in the sense of “missive”) to the world in general, and to Lancelot in particular, opens up a perspective on a premodern understanding of the practice of reading as a type of communal, gendered, and, above all, emotional and spatial performativity. Representing a decidedly theatrical type of performance, the two public readings of the Maid’s letter are rife with potential for manipulation and power struggles. And, ironically, it is ultimately the Maid of Astolat’s failure in putting into practice her elaborately planned scheme of spatial, affective, and performative self-assertion that makes this performative potential for power struggles so hauntingly visible in the first place.
A reminder of the story’s most central events, especially as they pertain to the argument presented here, will be useful – not least because the plot is not remotely as straightforward as has often been assumed. The story begins in Westminster where Lancelot and Guinevere quarrel over whether Lancelot ought to participate in a grand tournament King Arthur has announced to be held in Camelot (i.e., Winchester). A weary and battle-scarred Lancelot would prefer to skip this tournament.

There are many pressures on elite footballers. They work in a meritocracy, where only the best are selected and play at the highest levels. From the moment they enter an academy to their retirement there is a fear of deselection and rejection. Elite players need to contend with criticisms from fans and via social media; team and management dynamics can be stressful. Fears of injury are major concerns. In addition, the players are likely to face everyday difficulties experienced by the rest of society, such as relationship, family and financial problems. There is a great deal of stigma associated with mental health problems in footballers, hence approaches are required that are destigmatising. This article presents two frameworks conceptualising stress in footballers: the Power Threat Meaning Framework, which describes stress in non-diagnostic terms; and the Yerkes–Dodson curve, which describes how stress can affect footballers’ mental and physical performances on the pitch. Both frameworks can combine to enable therapists to understand players’ distress and its impact and to guide towards appropriate treatments, as we show in a fictitious case study.

Objectives:
The Canadian Nosocomial Infection Surveillance Program conducted point-prevalence surveys in acute-care hospitals in 2002, 2009, and 2017 to identify trends in antimicrobial use.
Methods:Eligible inpatients were identified from a 24-hour period in February of each survey year. Patients were eligible (1) if they were admitted for ≥48 hours or (2) if they had been admitted to the hospital within a month. Chart reviews were conducted. We calculated the prevalence of antimicrobial use as follows: patients receiving ≥1 antimicrobial during survey period per number of patients surveyed × 100%.
Results:In each survey, 28−47 hospitals participated. In 2002, 2,460 (36.5%; 95% CI, 35.3%−37.6%) of 6,747 surveyed patients received ≥1 antimicrobial. In 2009, 3,566 (40.1%, 95% CI, 39.0%−41.1%) of 8,902 patients received ≥1 antimicrobial. In 2017, 3,936 (39.6%, 95% CI, 38.7%−40.6%) of 9,929 patients received ≥1 antimicrobial. Among patients who received ≥1 antimicrobial, penicillin use increased 36.8% between 2002 and 2017, and third-generation cephalosporin use increased from 13.9% to 18.1% (P < .0001). Between 2002 and 2017, fluoroquinolone use decreased from 25.7% to 16.3% (P < .0001) and clindamycin use decreased from 25.7% to 16.3% (P < .0001) among patients who received ≥1 antimicrobial. Aminoglycoside use decreased from 8.8% to 2.4% (P < .0001) and metronidazole use decreased from 18.1% to 9.4% (P < .0001). Carbapenem use increased from 3.9% in 2002 to 6.1% in 2009 (P < .0001) and increased by 4.8% between 2009 and 2017 (P = .60).
Conclusions:The prevalence of antimicrobial use increased between 2002 and 2009 and then stabilized between 2009 and 2017. These data provide important information for antimicrobial stewardship programs.

We describe an ultra-wide-bandwidth, low-frequency receiver recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage from 704 to 4032 MHz. For much of the band (
${\sim}60\%$ ), the system temperature is approximately 22 K and the receiver system remains in a linear regime even in the presence of strong mobile phone transmissions. We discuss the scientific and technical aspects of the new receiver, including its astronomical objectives, as well as the feed, receiver, digitiser, and signal processor design. We describe the pipeline routines that form the archive-ready data products and how those data files can be accessed from the archives. The system performance is quantified, including the system noise and linearity, beam shape, antenna efficiency, polarisation calibration, and timing stability.

The small Greek island of Antikythera has a long history of human exploitation, of which one of the most interesting episodes is represented by a fortified settlement on the north coast of the island that can be plausibly identified as a centre of Hellenistic piratical activity. Hellenistic ‘Aegila’ has left both impressive standing remains and a range of portable finds that have attracted academic interest over much of the last two centuries. This paper examines the pottery assemblage from this period recovered during a recent intensive survey over the island's entire extent. We consider the spatial and typological character of this material as well as the implications it has for the Hellenistic community's wider social, economic and political connections.

A series of synthetic calcium silicates has been produced comprising nano-sized plates. The starting calcium silicate referred to as nano-structured calcium silicate, NCS, appears itself X-ray amorphous but contains impurities of calcite. These impurities decompose during the dry thermal conversion of the material into wollastonite. NCS can be enriched with calcium or silicon, respectively. The silicon enriched NCS can be hydrothermally transformed into a sheet material related to Ca7Si16O38(OH)2. The X-ray pattern of this material was sufficient to allow the calculation of its unit cell with a comparatively high figure of merit. The calcium enriched NCS can form two very distinctly different ceramic materials upon hydrothermal treatment, one a band material (formed below 200 °C) and the other a rose petal shaped material (formed above 210 °C). The X-ray diffraction patterns could not be resolved. The fit between the observed and calculated patterns was less than 50% as expressed in comparatively low figures of merit (unusually <20), which is attributed to calcium carbonate impurities in the samples disrupting the long range order. The patterns of these calcium enriched samples could be best compared to those of tobermorite or truscotite.

The relaxation of a reattached turbulent boundary layer downstream of a wall fence has been investigated. The boundary layer has an adverse pressure gradient imposed upon it which is adjusted in an attempt to bring the boundary layer into equilibrium. This is done by adjusting the pressure gradient so as to bring the Clauser parameter (G) down to a value of about 11.4 and then maintain it constant. In the region from the reattachment point to 2 or 3 reattachment lengths downstream, the boundary layer recovers from the initial major effects of reattachment. Farther downstream (where G is constant) the pressure-gradient parameter changes very slowly and profiles of non-dimensionalized eddy viscosity appear self-similar. However, pressure gradient and eddy viscosity are both roughly twice as large as expected on the basis of previous studies of equilibrium turbulent boundary layers. It is not known whether equilibrium has been achieved in this downstream region. This is another illustration of the great sensitivity of boundary-layer structure to perturbations.
