Australia\u27s solution to disability discrimination enforcement
[Excerpt] Until recently, Australian disability discrimination law was similar to that of the United States and much of the rest of the world: it defined disability relatively narrowly, its penalties for noncompliance were relatively paltry, and it depended on enforcement of lawsuits brought by aggrieved private citizens. In 2009, however, Australia adopted the Fair Work Act 2009 (FW Act). The FW Act defined disability much more broadly, increased substantially the penalties for noncompliance, and created a state institution to enforce disability rights. This article analyses the FW Act, compares it to the workplace disability law in the United States, and argues that the FW Act is a transformational development in the struggle to achieve workplace equality and is an approach that should attract significant international interest
Adjustable Head Tube Angle Headset
This final design review report describes the design, manufacture, and test process of a bicycle headset capable of quickly and easily adjusting the effective head tube angle. The evolution of mountain bike geometry has forced bike designers to compromise between climbing and descending performance when choosing a head tube angle. A headset capable of quickly adjusting the effective head tube angle would allow riders to optimize their bikeβs geometry for different stages of riding. This report details the research, idea generation, concept development and selection, design, manufacturing, and testing of our adjustable head tube angle headset
Learning management systems: one size fits all?
Learning management systems such as WebCT and Blackboard are rapidly becoming the principal systems behind institutions' moves to technology-based learning settings. In settings where lecturers have had no or limited exposure to ICT as a teaching tool, LMSs pave the way for quick introduction and eventual adoption of technology-based teaching practices. Many lecturers quickly progress and grow in the field. But there are those who argue that the use of LMS tend to be counter-productive and that in their current forms, they cannot be used effectively as a learning tool. Critics argue that they support only traditional forms of teaching and encourage poor learning designs in their implementation. This panel will explore LMSs as they exist today and will explore whether they are the solution to a pressing problem or in fact problems within themselves
Perspectives of applied collaborative sport science research within professional team sports
The purpose of the study was to examine the perspectives of both academics and practitioners in relation to forming applied collaborative sports science research within team sports. Ninety-three participants who had previously engaged in collaborative research partnerships within team sports completed an online survey which focused on motivations and barriers for forming collaborations using blinded sliding scale (0-100) and rank order list. Research collaborations were mainly formed to improve team performance (Academic: 73.6 Β± 23.3; Practitioner: 84.3 Β± 16.0; ES = 0.54, small). Academics ranked journal articles importance significantly higher than practitioners (Academic: Mrank = 53.9; Practitioner 36.0; z = -3.18, p = .001, p < q). However, practitioners rated one-to-one communication as more preferential (Academic: Mrank = 41.3; Practitioner 56.1; z = -2.62, p = .009, p < q). Some potential barriers were found in terms of staff buy in (Academic: 70.0 Β± 25.5; Practitioner 56.8 Β± 27.3; ES = 0.50, small) and funding (Academic: 68.0 Β± 24.9; Practitioner: 67.5 Β± 28.0; ES = 0.02, Trivial). Both groups revealed low motivation for invasive mechanistic research (Academic: 36.3 Β± 24.2; Practitioner: 36.4 Β± 27.5; ES = 0.01, trivial), with practitioners have a preference towards βfastβ type research. There was a general agreement between academics and practitioners for forming research collaborations. Some potential barriers still exist (e.g. staff buy in and funding), with practitioners preferring βfastβ informal research dissemination compared to the βslowβ quality control approach of academics
Do Γ la carte menus serve infertility patients? The ethics and regulation of in vitro fertility add-ons
Add-on treatments are the new black. They are provided (most frequently, sold) to patients undergoing in vitro fertilization on the premise that they will improve the chances of having a baby. However, the regulation of add-ons is consistently minimal, meaning that they are introduced into routine practice before they have been shown to improve the live birth rate. Debate on the adequacy of this light-touch approach rages. Defenders argue that demands for a rigorous approval process are paternalistic, as this would delay access to promising treatments. Critics respond that promising treatments may turn out to have adverse effects on patients and their offspring, contradicting the clinician's responsibility to do no harm. Some add-ons, including earlier versions of preimplantation genetic testing for aneuploidy, might even reduce the live birth rate, raising the prospect of desperate patients paying more to worsen their chances. Informed consent represents a solution in principle, but in practice there is a clear tension between impartial information and direct-to-consumer advertising. Because the effects of a treatment cannot be known until it has been robustly evaluated, we argue that strong evidence should be required before add-ons are introduced to the clinic. In the meantime, there is an imperative to identify methods for communicating the associated risks and uncertainties of add-ons to prospective patients
Fis Is Essential for Capsule Production in Pasteurella multocida and Regulates Expression of Other Important Virulence Factors
P. multocida is the causative agent of a wide range of diseases of animals, including fowl cholera in poultry and wild birds. Fowl cholera isolates of P. multocida generally express a capsular polysaccharide composed of hyaluronic acid. There have been reports of spontaneous capsule loss in P. multocida, but the mechanism by which this occurs has not been determined. In this study, we identified three independent strains that had spontaneously lost the ability to produce capsular polysaccharide. Quantitative RT-PCR showed that these strains had significantly reduced transcription of the capsule biosynthetic genes, but DNA sequence analysis identified no mutations within the capsule biosynthetic locus. However, whole-genome sequencing of paired capsulated and acapsular strains identified a single point mutation within the fis gene in the acapsular strain. Sequencing of fis from two independently derived spontaneous acapsular strains showed that each contained a mutation within fis. Complementation of these strains with an intact copy of fis, predicted to encode a transcriptional regulator, returned capsule expression to all strains. Therefore, expression of a functional Fis protein is essential for capsule expression in P. multocida. DNA microarray analysis of one of the spontaneous fis mutants identified approximately 30 genes as down-regulated in the mutant, including pfhB_2, which encodes a filamentous hemagglutinin, a known P. multocida virulence factor, and plpE, which encodes the cross protective surface antigen PlpE. Therefore these experiments define for the first time a mechanism for spontaneous capsule loss in P. multocida and identify Fis as a critical regulator of capsule expression. Furthermore, Fis is involved in the regulation of a range of other P. multocida genes including important virulence factors
Evaluating the impact of a very low-cost intervention to increase practicesβ engagement with data and change prescribing behaviour: a randomized trial in English primary care
Background
Unsolicited feedback can solicit changes in prescribing.
Objectives
Determine whether a low-cost intervention increases cliniciansβ engagement with data, and changes prescribing; with or without behavioural science techniques.
Methods
Randomized trial (ISRCTN86418238). The highest prescribing practices in England for broad-spectrum antibiotics were allocated to: feedback with behavioural impact optimization; plain feedback; or no intervention. Feedback was sent monthly for 3 months by letter, fax and email. Each included a link to a prescribing dashboard. The primary outcomes were dashboard usage and change in prescribing.
Results
A total of 1401 practices were randomized: 356 behavioural optimization, 347 plain feedback, and 698 control. For the primary engagement outcome, more intervention practices had their dashboards viewed compared with controls [65.7% versus 55.9%; RD 9.8%, 95% confidence intervals (CIs): 4.76% to 14.9%, P < 0.001]. More plain feedback practices had their dashboard viewed than behavioural feedback practices (69.1% versus 62.4%); but not meeting the P < 0.05 threshold (6.8%, 95% CI: β0.19% to 13.8%, P = 0.069). For the primary prescribing outcome, intervention practices possibly reduced broad-spectrum prescribing to a greater extent than controls (1.42% versus 1.12%); but again not meeting the P < 0.05 threshold (coefficient β0.31%, CI: β0.7% to 0.1%, P = 0.104). The behavioural impact group reduced broad-spectrum prescribing to a greater extent than plain feedback practices (1.63% versus 1.20%; coefficient 0.41%, CI: 0.007% to 0.8%, P = 0.046). No harms were detected.
Conclusions
Unsolicited feedback increased practicesβ engagement with data, with possible slightly reduced antibiotic prescribing (P = 0.104). Behavioural science techniques gave greater prescribing effects. The modest effects on prescribing may reflect saturation from similar initiatives on antibiotic prescribing.

The Effects of Fixture Congestion on Injury in Professional Male Soccer: A Systematic Review
Methods
Following pre-registration on the Open Science Framework (https://osf.io/86m25/) and conforming with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, systematic searches of four electronic databases (PubMed, Scopus, SPORTDiscus, and Web of Science) were conducted by independent researchers from inception until February 2022. Articles were included if they were original articles written in English and contained relevant time-loss injury data (injury that results in unavailability for training and/or match-play) for male professional soccer players regarding periods of fixture congestion (a minimum of two matches withββ€β4 days recovery).
Results
A total of eight articles were included in the review. Five studies identified that congested fixture schedules expose players to increased match injury incidence, although layoff duration was typically lower during congested periods. Two studies identified that training and overall injury incidence were higher during congested periods, with another study identifying a lower training injury incidence during congested periods.
Conclusion
Injury risk is, overall, increased during fixture-congested periods; however, the layoff duration is typically shorter. The current findings have implications for practitioners regarding the management, periodisation, monitoring, and design of training and competition schedules
