To deliver a comprehensive learning experience while shifting to online teaching due to COVID-19, educators at The University of Queensland (Australia) adopted Lt, a cloud-based platform, to overcome the challenges of delivering animal anatomy practicals. A two-phased study was conducted to evaluate the use of Lt for both online and on-campus students and its impact on student satisfaction and performance. Phase 1 investigated students' satisfaction with the practical experience, with online students expressing greater satisfaction across all constructs related to the practical: design, Lt, and feedback. Phase 2 investigated end-of-course evaluations, with all evaluated items increasing from 2019 to 2020 and 2021, along with student performance showing no difference between the online and on-campus students for practical assessment items and final examinations. The findings give confidence for technology adoption to enhance the learning experience for online students and provides an exemplar for similar adoption for practical delivery across other science disciplines.

Much of the student-staff partnership literature calls for increased collaboration and power sharing among staff and students. Less common are accounts by student partners themselves that take up the challenge of what partnership and power feel like as universities embrace their neoliberal trajectory - and - purport to do so on behalf of students themselves. Especially acute is the conundrum of how partnership initiatives can, and do, reproduce the very power dynamics they set out to transform. We are a group of students and staff working in curriculum partnership together at Western Sydney University. The context of our work together is the 21C project, a university-wide strategy to transform curriculum, teaching, and learning, drawing on 'partnership pedagogy'. In this paper, we engage in a process of reflexive inquiry to interrogate a new elective unit that many of us are involved in as advocates, co-creators, as students and staff learning together, and as evaluators, called "We are the university: Students co-creating change" (WATU). To highlight partnership's intricate power plays, we offer a fictionalised account to reflect our multi-voiced experiences of being involved in WATU. We have come to understand power's simultaneity in partnership as forms of power "over," as "permission-giving," as "sharing (or partnership)," and as the power "to act (agency)." The account is our story of partnership's inevitable contradictions - a collaboration that teaches us about the challenges of working together while being cautious of partnership's transformatory claims.

Sociolinguists have recently employed the notion of spatiotemporal scales to explain the changing social status of linguistic codes across social and geopolitical domains. Scales enable us to address the portability of semiotic resources in migration with great insight. In addition, unlike romanticized orientations to globalization and transnational relations, this model enables us to address the role of power in shaping the uptake of resources in shifting social contexts. Sociolinguists in this tradition show how the resources that enjoy power and prestige in certain local contexts receive lower status as migrants move to other social contexts, especially in Western urban communities. Despite the usefulness of this orientation, the sociolinguistics of scale suffers from certain limitations. It presents a highly stratified vision of social spaces, ignoring the possibility for renegotiating status differences and hierarchies. It assumes a normative orientation to languages, unable to accommodate the possibility that new language norms and practices might emerge, leading to new orders of indexicality. For these reasons, it is also insensitive to agency in mobility, unable to theorize how migrants may renegotiate norms in elite and privileged contexts. I present interview data from African skilled migrants in the UK, USA, and Australia to demonstrate their attitudes toward renegotiating the valuation and status of their own varieties of English in transnational contexts. Their narratives suggest how migrants negotiate spatiotemporal scales to their advantage, redefine the translocal space, and reconstruct new orders of indexicality in intercultural communication. Though I lack interactional data to examine uptake, the interview data helps develop a more complex use of scalar metaphors to address the dynamics of agency and inequality in intercultural communication in translocal spaces.

Summary Background Increased detection of small-sized, peripheral, non-small-cell lung cancer has renewed interest in sublobar resection instead of lobectomy, the traditional standard of care for early-stage lung cancer. We aimed to assess morbidity and mortality associated with lobar and sublobar resection for early-stage lung cancer. Methods CALGB/Alliance 140503 is a multicentre, international, non-inferiority, phase 3 trial in patients with peripheral non-small-cell lung cancer clinically staged as T1aN0. Patients were recruited from 69 academic and community-based institutions in Australia, Canada, and the USA. Patients were randomly assigned intraoperatively to either lobar or sublobar resection. The random assignment was based on permuted block randomisation without concealment and was stratified according to radiographic tumour size, histology, and smoking status. The primary endpoint of the trial is disease-free survival; here, we report a post-hoc, exploratory, comparative analysis of perioperative mortality and morbidity associated with lobar and sublobar resection. Perioperative mortality was defined as death from any cause within 30 days and 90 days of surgical intervention and was calculated for all randomised patients. Morbidity was graded using Common Terminology Criteria for Adverse Events version 4.0. All analyses were done on an intention-to-treat basis for randomised patients with data available. This trial is registered with ClinicalTrials.gov , number NCT00499330. Findings Between June 15, 2007, and March 13, 2017, 697 patients were randomly allocated to either lobar resection (n=357) or sublobar resection (n=340; 59% wedge resection). Six (0·9%) patients died by 30 days, four (1·1%) after lobar resection and two (0·6%) after sublobar resection; by 90 days, ten (1·4%) patients had died, six (1·7%) after lobar resection and four (1·2%) after sublobar resection (difference at 30 days, 0·5%, 95% CI −1·1 to 2·3; difference at 90 days, 0·5%, 95% CI −1·5 to 2·6). An adverse event of any grade occurred in 193 (54%) of 355 patients after lobar resection and 172 (51%) of 337 patients after sublobar resection. Adverse events of grade 3 or worse occurred in 54 (15%) patients assigned lobar resection and in 48 (14%) patients assigned sublobar resection. No differences between surgical approaches were noted in cardiac or pulmonary complications. Grade 3 haemorrhage (requiring transfusion) occurred in six (2%) patients assigned lobar resection and eight (2%) patients assigned sublobar resection. Prolonged air leak occurred in nine (3%) patients after lobar resection and two (1%) patients after sublobar resection. Interpretation Our post-hoc analysis showed that perioperative mortality and morbidity did not seem to differ between lobar and sublobar resection in physically and functionally fit patients with clinical T1aN0 non-small-cell lung cancer. These data may affect the daily choices made by patients and their doctors in establishing the best treatment approach for stage I lung cancer. Funding National Cancer Institute.

Melioidosis was diagnosed in two domestic crossbred cats presented for unilateral ocular disease. One patient was born and bred in Nhulunbuy, Arnhem Land, while the other had moved there 6 months previously from Townsville, Queensland. Both patients were presented with sudden onset of a ‘red eye’ and blepharospasm, which progressed to an enlarged, painful, firm globe with loss of pupillary light reflexes and vision. An obvious primary focus of infection outside the eye was not detected in either cat. In both patients, the affected eye was surgically removed and vitreal culture revealed a pure growth of Burkholderia pseudomallei. In each instance, the infection had penetrated the sclera to produce retrobulbar cellulitis, and in one case frank retrobulbar abscessation. Histologically, there was a pyogranulomatous uveitis with extensive destruction of intraocular structures. The first case was still alive approximately 1 year following enucleation and limited antimicrobial therapy using amoxicillin clavulanate and doxycycline. The second was euthanased when a localised abscess developed on the same side of the face as the healed surgical incision, despite appropriate antimicrobial therapy. Both cases were caused by the same multilocus sequence type of B pseudomallei (ST 116), which had only been isolated previously from two human patients, both living in the same isolated geographical area as the cats of this report. Apart from the geographical clustering, no epidemiological links were evident between the two cats and/or the two people. The presumptive pathogenesis of these infections is discussed in relation to current knowledge about melioidosis in northern Australia. [Copyright &y& Elsevier]

Abstract: Key attributes of the source zone and the expanding dissolved plume at a trichloroethene (TCE) site in Australia were evaluated using trends in groundwater monitoring data along with data from on-line volatile organic compound (VOC) samplers and passive flux meters (PFMs) deployed in selected wells. These data indicate that: (1) residual TCE source mass in the saturated zone, estimated using two innovative techniques, is small (∼10 kg), which is also reflected in small source mass discharge (∼3 g/day); (2) the plume is disconnecting, based on TCE concentration contours and TCE fluxes in wells along a longitudinal transect; (3) there is minimal biodegradation, based on TCE mass discharge of ∼6 g/day at a plume control plane ∼175 m from source, which is also consistent with aerobic geochemical conditions observed in the plume; and (4) residual TCE in the vadose zone provides episodic inputs of TCE mass to the plume during infiltration/recharge events. TCE flux data also suggest that the small residual TCE source mass is present in the low-permeability zones, thus making source treatment difficult. Our analysis, based on a synthesis of the archived data and new data, suggests that source treatment is unwarranted, and that containment of the large TCE plume (∼1.2 km long, ∼0.3 km wide; 17 m deep; ∼2000–2500 kg TCE mass) or institutional controls, along with a long-term flux monitoring program, might be necessary. The flux-based site management approach outlined in this paper provides a novel way of looking beyond the complexities of groundwater contamination in heterogeneous domains, to make intelligent and informed site decisions based on strategic measurement of the appropriate metrics.
