Collaborative Writing as an Exercise of Poetic Resistance in Teacher Education
Over the last decade we have strived through a collaborative writing project to open a polyvocal and layered conversation on critical contemporary issues in teacher education, even as our program faced its demise. Our writing inquiries began as a critical thinking-through of the qualities of lived experiences as instructors within an innovative and now defunct teacher education program. The context for our work was a radically construed approach to teacher education thatâin its language, form, and curriculumâchallenged prevailing norms of practice. In our collaborative writing we confront the difficult work of teacher education, addressing specific challenges, complex demands, and forms of resistance that are prevalent in faculties of education everywhere. Such challenges include how we narrate alternative visions of teacher education, attend to issues of ethics and recognition, deal with the complexities of learning professional practice and take into account the larger, historical project of teacher education. As a provocative example of self-study research, our collaborative method of inquiry illustrates the richness and productivity of poetic, practice-based research, oriented to critical issues in teacher education. The intentional effort to make our work public and politically provocative is an attempt by the authors to reveal the importance of these critical conversations in advancing our work. Specifically, what makes such conversations important includes questions about how we should enact our responsibilities for teacher education and also how we give account for enacting those responsibilities. We intend our conversations and thinking-through about practices in teacher education to remain open-ended and responsive to a plurality of thought and experience. Collaborative writing serves for us as a kind of resistance, reclaiming, re-storying, and historical accounting through encounters with others
Provoking and Being Provoked by Embodied Qualities of Learning: Listening, Speaking, Seeing, and Feeling (Through) Inquiry in Teacher Education
Preâemptive and preventive opioids for postoperative pain in adults undergoing all types of surgery
Background: Postoperative pain is a common consequence of surgery and can have deleterious effects. It has been suggested that the administration of opioid analgesia before a painful stimulus may improve pain control. This can be done in two ways. We defined 'preventive opioids' as opioids administered before incision and continued postoperatively, and 'preâemptive opioids' as opioids given before incision but not continued postoperatively. Both preâemptive and preventive analgesia involve the initiation of an analgesic agent prior to surgical incision with the aim of reducing intraoperative nociception and therefore postoperative pain.Objectives: To assess the efficacy of preventive and preâemptive opioids for reducing postoperative pain in adults undergoing all types of surgery.Search methods: We searched the following electronic databases: CENTRAL, MEDLINE, Embase, AMED, and CINAHL (up to 18 March 2018). In addition, we searched for unpublished studies in three clinical trial databases, conference proceedings, grey literature databases, and reference lists of retrieved articles. We did not apply any restrictions on language or date of publication.Selection criteria: We included parallelâgroup randomized controlled trials (RCTs) only. We included participants aged over 15 years old undergoing any type of surgery. We defined postincision opioids as the same intervention administered after incision whether single dose (as comparator with preâemptive analgesia) or continued postoperatively (as comparator with preventive analgesia) (control group). We considered studies that did and did not use a doubleâdummy placebo (e.g. intervention group received active drug before incision and placebo after incision; control group received placebo before incision and active drug after incision).Data collection and analysis: We used the standard methodological procedures expected by Cochrane. Our primary outcomes were: early acute postoperative pain (measured within six hours and reported on a 0âtoâ10 scale) and respiratory depression. Our secondary outcomes included: late acute postoperative pain (24 to 48 hours and reported on a 0âtoâ10 scale), 24âhour morphine consumption, and adverse events (intraoperative bradycardia and hypotension). We used GRADE to assess the quality of the evidence for each outcome.Main results: We included 20 RCTs, including one unpublished study with 1343 participants. Two studies were awaiting classification as the full text for these studies was not available. One study evaluated preâemptive opioids, and 19 studies evaluated preventive opioids. We considered only one study to be at low risk of bias for most domains. The surgeries and opioids used varied, although roughly half of the included studies were conducted in abdominal hysterectomy, and around a quarter used morphine as the intervention. All studies were conducted in secondary care.Preâemptive opioids compared to postincision opioidsFor preâemptive opioids in dental surgery, there may be a reduction in early acute postoperative pain (mean difference (MD) â1.20, 95% confidence interval (CI) â1.75 to â0.65; 40 participants; 1 study; lowâquality evidence). This study did not report on adverse events (respiratory depression, bradycardia, or hypotension). There may be a reduction in late acute postoperative pain (MD â2.10, 95% CI â2.57 to â1.63; 40 participants; 1 study; lowâquality evidence). This study did not report 24âhour morphine consumption.Preventive opioids compared to postincision opioidsFor preventive opioids, there was probably no reduction in early acute postoperative pain (MD 0.11, 95% CI â0.32 to 0.53; 706 participants; 10 studies; I2 = 61%; moderateâquality evidence). There were no events of respiratory depression in four studies (433 participants). There was no important reduction in late acute postoperative pain (MD â0.06, 95% CI â0.13 to 0.01; 668 participants; 9 studies; I2 = 0%; moderateâquality evidence). There may be a small reduction in 24âhour morphine consumption (MD â4.91 mg, 95% CI â9.39 mg to â0.44 mg; 526 participants; 11 studies; I2 = 82%; very lowâquality evidence). There may be similar rates of bradycardia (risk ratio (RR) 0.33, 95% CI 0.01 to 7.88; 112 participants; 2 studies; I2 = 0%; lowâquality evidence) and hypotension (RR 1.08, 95% CI 0.25 to 4.73; 88 participants; 2 studies; I2 = 0%; lowâquality evidence).Authors' conclusions: Due to the low quality of the evidence, we are uncertain whether preâemptive opioids reduce postoperative pain. Based on the trials conducted thus far, there was no clear evidence that preventive opioids result in reductions in pain scores. It was unclear if there was a reduction in morphine consumption due to very lowâquality of evidence. Too few studies reported adverse events to be able to draw any definitive conclusions. Once assessed, the two studies awaiting classification may alter the conclusions of the review
Readmissions and the quality of care in patients hospitalized with heart failure
Objectives. Clinical practice guidelines based on the results of randomized clinical trials recommend that patients with heart failure due to left ventricular systolic dysfunction (LVSD) be treated with angiotensin-converting enzyme inhibitors (ACEI) at doses shown to reduce mortality and readmission. This study examined the relationship between ACEI use at discharge and readmission among patients with heart failure due to LVSD. Methods and results. Data were abstracted from the medical records of 2943 randomly selected patients hospitalized for heart failure in 50 hospitals. The outcome of interest was the number of readmissions occurring up to 21 months after discharge. Six-hundred and eleven patients were eligible for analysis. Compared with patients discharged at a recommended ACEI dose, patients not prescribed an ACEI at discharge had an adjusted rate ratio of readmission (RR) of 1.74 [95% confidence interval (CI) 1.22-2.48], while patients prescribed an ACEI at less than a recommended dose had an RR of 1.24 (95% CI 0.91-1.69) (P = 0.005 for the trend). Conclusion. Our results show that ACEI use at discharge in patients with LVSD is associated with decreased rate of readmission. These findings suggest that compliance with the ACEI prescribing recommendations listed in clinical practice guidelines for patients with heart failure due to LVSD confers benefi
Ultraearly thrombolysis by an anesthesiologist in a mobile stroke unit: A prospective, controlled intervention study
Background
Acute stroke treatment in mobile stroke units (MSU) is feasible and reduces time-to-treatment, but the optimal staffing model is unknown. We wanted to explore if integrating thrombolysis of acute ischemic stroke (AIS) in an anesthesiologist-based emergency medical services (EMS) reduces time-to-treatment and is safe.
Methods
A nonrandomized, prospective, controlled intervention study. Inclusion criteria: age â„18 years, nonpregnant, stroke symptoms with onset â€4 h. The MSU staffing is inspired by the Norwegian Helicopter Emergency Medical Services crew with an anesthesiologist, a paramedic-nurse and a paramedic. Controls were included by conventional ambulances in the same catchment area. Primary outcome was onset-to-treatment time. Secondary outcomes were alarm-to-treatment time, thrombolytic rate and functional outcome. Safety outcomes were symptomatic intracranial hemorrhage and mortality.
Results
We included 440 patients. MSU median (IQR) onset-to-treatment time was 101 (71â155) minutes versus 118 (90â176) minutes in controls, p = 0.007. MSU median (IQR) alarm-to-treatment time was 53 (44â65) minutes versus 74 (63â95) minutes in controls, p < 0.001. Golden hour treatment was achieved in 15.2% of the MSU patients versus 3.7% in the controls, p = 0.005. The thrombolytic rate was higher in the MSU (81% vs 59%, p = 0.001). MSU patients were more often discharged home (adjusted OR [95% CI]: 2.36 [1.11â5.03]). There were no other significant differences in outcomes.
Conclusions
Integrating thrombolysis of AIS in the anesthesiologist-based EMS reduces time-to-treatment without negatively affecting outcomes. An MSU based on the EMS enables prehospital assessment of acute stroke in addition to other medical and traumatic emergencies and may facilitate future implementation.publishedVersio

Synthesis and Characterization of Doped Magnesium Hydroxide for Medium Heat Storage Application
The amount of waste heat generated annually in the UK exceeds the total annual electricity demand. Hence, it is crucial to effectively harness all available sources of waste heat based on their varying temperatures. Through suitable technologies, a substantial portion of this waste heat has the potential to be recovered for reutilization. Thermochemical energy storage (TCES) provides the best opportunities to recover waste heat at various temperatures for long-term storage and application. The potential of TCES with magnesium hydroxide, Mg(OH)2, has been established, but it has a relatively high dehydration temperature, thus limiting its potential for medium-temperature heat storage applications, which account for a vast proportion of industrial waste heat. To this end, samples of doped Mg(OH)2 with varying proportions (5, 10, 15, and 20 wt%) of potassium nitrate (KNO3) have been developed and characterized for evaluation. The results showed that the Mg(OH)2 sample with 5 wt% KNO3 achieved the best outcome and was able to lower the dehydration temperature of the pure Mg(OH)2 from about 317 °C to 293 °C with an increase in the energy storage capacity from 1246 J/g to 1317 J/g. It also showed a monodisperse surface topology and thermal stability in the non-isothermal test conducted on the sample and therefore appears to have the potential for medium heat storage applications ranging from 293 °C to 400 °C
"Now he walks and walks, as if he didn't have a home where he could eat": food, healing, and hunger in Quechua narratives of madness
In the Quechua-speaking peasant communities of southern Peru, mental disorder is understood less as individualized pathology and more as a disturbance in family and social relationships. For many Andeans, food and feeding are ontologically fundamental to such relationships. This paper uses data from interviews and participant observation in a rural province of Cuzco to explore the significance of food and hunger in local discussions of madness. Carersâ narratives, explanatory models, and theories of healing all draw heavily from idioms of food sharing and consumption in making sense of affliction, and these concepts structure understandings of madness that differ significantly from those assumed by formal mental health services. Greater awareness of the salience of these themes could strengthen the input of psychiatric and psychological care with this population and enhance knowledge of the alternative treatments that they use. Moreover, this case provides lessons for the global mental health movement on the importance of openness to the ways in which indigenous cultures may construct health, madness, and sociality. Such local meanings should be considered by mental health workers delivering services in order to provide care that can adjust to the alternative ontologies of sufferers and carers
Resonant Auger spectroscopy at the L2,3 shake-up thresholds as a probe of electron correlation effects in nickel
The excitation energy dependence of the three-hole satellites in the
L3-M4,5M4,5 and L2-M4,5M4,5 Auger spectra of nickel metal has been measured
using synchrotron radiation. The satellite behavior in the non-radiative
emission spectra at the L3 and L2 thresholds is compared and the influence of
the Coster-Kronig channel explored. The three-hole satellite intensity at the
L3 Auger emission line reveals a peak structure at 5 eV above the L3 threshold
attributed to resonant processes at the 2p53d9 shake-up threshold. This is
discussed in connection with the 6-eV feature in the x-ray absorption spectrum.Comment: 8 pages, 4 figures; http://prb.aps.org/abstract/PRB/v58/i7/p3677_
