Impacts of directed tutorial activities in computer conferencing: a case study
This paper describes a qualitative study of asynchronous electronic conferencing by three tutorial groups on the same postgraduate course (Teaching English to Speakers of Other Languages Worldwide), forming part of an MA in Applied Linguistics (via Distance Education) at the Open University, UK. The groups varied in the degree to which the tutor participated in the discussion and in whether the tutor's input took the form of responding to student posts or the setting of tasks to scaffold the learners' development of academic skills. It is argued that the least interventionist strategy in terms of tutor response and task-setting resulted in the least productive conference discussion in terms of both communicative interaction and academic development, while a more interventionist role by the tutor depended for its success on characteristics of the tutor input and the task set

Argumentation in a multi party asynchronous computer mediated conference: a generic analysis
This paper draws on systemic functional linguistic genre analysis to illuminate the way in which post graduate applied linguistics students structure their argumentation within a multi party asynchronous computer mediated conference. Two conference discussions within the same postgraduate course are compared in order to reveal the way in which computer-based argumentation may differ from that operating in written essays and to show the influence of tutor role and task set in shaping the discussions in this mode. The analysis undertaken demonstrates differences in both conferences between the ‘stages’ found in written argument and those found in the electronic discussion and also differences between the two conference discussions attributable to differences in the discussion task. In particular, in one conference, there was a higher frequency of counter-argumentation, while in the other there was a greater degree of disclosing personal and professional experiences on the basis of which participants (often collaboratively) constructed claims. It is hoped that these findings will point to fruitful new lines of enquiry both in terms of a) the special characteristics of computer mediated conferencing, particularly its use within an educational context and b) the methods of analysis which we developed as a means of illuminating a relatively new form of communication
Patterns of debate in tertiary level asynchronous text-based conferencing
Argumentation can be defined at different levels and serve different purposes, but its role in knowledge understanding and construction has given it a central place in education, particularly at tertiary level. The advent of computer-supported text-based conferences has created new sites where such educational dialogues can take place, but the quality of the interaction and whether it is serving its educational purpose is still uncertain. This paper reports on a framework of analysis that has been developed to illuminate the arguing process within an asynchronous electronic conferencing environment, showing how it is both similar to, and different from, argumentation in the more traditional forums of multi-party, face-to-face discussion and traditional written essays. The framework develops earlier work by the authors and is applied to two electronic conferences within the same postgraduate course, comparing overall patterns of argumentation. Findings are presented on the extent to which the technology of electronic conferencing shapes and supports students’ participation in academic literacy practices relating to argumentation, proposing, at the same time, that the teaching strategy adopted by the lecturer is also an important variable
Overlapping Agencies: The Collision of Cancer, Consumers, and Corporations in Richard Powers’s Gain
Richard Powers\u27s 1998 novel Gain establishes a complicated relationship between its two main characters, a corporation called Clare International and suburban mom named Laura Bodey. Readers, assuming the malignity of such corporations, mistake the hints Laura encounters that Clare is responsible for her ovarian cancer for facts. Such readings overlook the science of ovarian cancer as well as how Powers depicts Laura\u27s relation to her disease. I analyze Laura\u27s understudied half of the novel, framing it as a cancer narrative that reworks conventions of that genre. In placing her cancer in broad social and environmental contexts, Powers eschews the individualist strain that characterizes many illness narratives. In so doing, the novel demands engagement with consumer agency and bodily frailty in the face of corporate dominance
Aquatic Macroinvertebrate Biodiversity Associated with Artificial Agricultural Drainage Ditches
Agricultural drainage channels and ditches are ubiquitous features in the lowland agricultural landscapes, built primarily to facilitate land drainage, irrigate agricultural crops and alleviate flood risk. Most drainage ditches are considered artificial waterbodies and are not typically included in routine monitoring programmes, and as a result the faunal and floral communities they support are poorly quantified. This paper characterizes the aquatic macroinvertebrate diversity (alpha, beta and gamma) of agricultural drainage ditches managed by an internal drainage board in Lincolnshire, UK. The drainage ditches support very diverse macroinvertebrate communities at both the site (alpha diversity) and landscape scale (gamma diversity) with the main arterial drainage ditches supporting greater numbers of taxa when compared to smaller ditches. Examination of the between site community heterogeneity (beta diversity) indicated that differences among ditches were high spatially and temporally. The results illustrate that both main arterial and side ditches make a unique contribution to aquatic biodiversity of the agricultural landscape. Given the need to maintain drainage ditches to support agriculture and flood defence measures, we advocate the application of principles from ‘reconciliation ecology’ to inform the future management and conservation of drainage ditches
A Design Exploration of Health-Related Community Displays
The global population is ageing, leading to shifts in healthcare needs. It is well established that increased physical activity can improve the health and wellbeing of many older adults. However, motivation remains a prime concern. We report findings from a series of focus groups where we explored the concept of using community displays to promote physical activity to a local neighborhood. In doing so, we contribute both an understanding of the design space for community displays, as well as a discussion of the implications of our work for the broader CSCW community. We conclude that our work demonstrates the potential for developing community displays for increasing physical activity amongst older adults
Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
Multiorgan MRI findings after hospitalisation with COVID-19 in the UK (C-MORE): a prospective, multicentre, observational cohort study
Introduction:
The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures.
Methods:
In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025.
Findings:
Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2–6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5–5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4–10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32–4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23–11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation.
Interpretation:
After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification
