Classroom Management Scripts : a Theoretical Model Contrasting Expert and Novice Teachers’ Knowledge and Awareness of Classroom Events
Publisher Copyright: © 2020, The Author(s).Dealing with the complexities of the classroom and the diversity of events in classroom situations presents a major challenge for classroom management. The knowledge a teacher has for processing this complexity depends a great deal on their level of experience, leading to differences in the way teachers perceive and interpret classroom events. This includes how they monitor events and how they maintain an ongoing awareness of classroom situations. It also impacts decisions about when and how to act in response to events. Research on classroom management has often focused on how to handle common classroom situations, but does not provide a theoretical description of how knowledge from experience affects teachers’ awareness and ability to manage the classroom. This article proposes a definition for classroom management scripts by contrasting expert and novice teachers’ knowledge and their decisions to act in response to classroom events. Classroom management scripts help clarify differences in teachers’ recognition and representation of events by considering how expertise influences visual perception and mental interpretation. The proposed model exposes the internal cognitive processing involved in classroom management. Such insights can be useful for helping teacher educators and teachers themselves analyze and make sense of puzzling events. In turn, this may help develop training approaches to improve teachers’ awareness of factors easily overlooked when considering classroom management, enhancing professional vision. This theory also underlines the centrality of facilitating and sustaining learning when grappling with the challenges of managing a classroom.Peer reviewe

Inclusive Education in the diversifying environments of Finland, Iceland, and the Netherlands : A multilingual systematic review
This review investigates how the scholarly fields, themes and concepts of 'inclusive education' are applied in the research and educational contexts of Finland, Iceland and the Netherlands. It identifies and outlines which thematic areas of research and sub-fields of study are referenced in each country by applying a systematic, multilingual approach. We reviewed literature in the local languages of each of these countries over the past decade, from 2007 to 2018, paying particular attention to (a) micro-level, in-depth, classroom interactions; (b) social and political contexts; and (c) social categories. Results of this review emphasise that across all three countries (a) there are similar conceptualisations of inclusive education dominated by categories of disability and special needs, and (b) there is a similar lack of attention to modes of exclusion based on social class, gender, ethnicity and geography as well as to how these can be addressed by more advanced research on inclusive education in these local spheres.Peer reviewe
Exploring preservice, beginning and experienced teachers' noticing of classroom management situations from an actor's perspective
Publisher Copyright: © 2021 The AuthorsWe investigated preservice (n = 21), beginning (n = 17) and experienced (n = 19) teachers' noticing of salient classroom management situations during teaching. Teachers wore a front-view camera while teaching. A two-method approach was used to identify salient situations and verbalizations of accompanying cognitions: hand-signals while teaching and stimulated-recall interview. Mixed-method analysis showed that teacher groups noticed similar amounts and types of situations distributed across the lesson time. Preservice teachers identified more situations than beginners in interviews, whereas beginners identified more situations by hand-signaling while teaching. Findings indicate non-linear professional development of teachers' noticing and the value of a two-method approach to capture teachers’ noticing.Peer reviewe
Factors associated with positive urine cultures in cats with subcutaneous ureteral bypass system implantation
Objectives
The aims of this study were to report the postoperative incidence of subcutaneous ureteral bypass (SUB)-associated bacteriuria and risk factors in a large population of UK cats, to identify the commonly implicated isolates in these cases and to report associations of positive postoperative urine cultures with device occlusion or a need for further surgery.
Methods
Electronic clinical records were reviewed to identify cats with ureteral obstruction that underwent unilateral or bilateral SUB implantation between September 2011 and September 2019. In total, 118 client-owned cats were included in the study population. Information recorded included signalment, history, surgical and biochemical factors, urinalysis and culture results. Multivariable logistic regression was performed to identify variables associated with a positive postoperative culture.
Results
In total, 10 cats (8.5%) had a positive postoperative culture within 1 month postsurgery and 28 cats (23.7%) within 1 year postsurgery. Cats with a positive preoperative culture were significantly more likely to have a positive culture within 6 months postoperatively (odds ratio [OR] 4.09, 95% confidence interval [CI] 1.18–14.18; P = 0.026). Of the 14 cats with a positive preoperative culture, six (42.9%) returned a positive culture within 1 year postoperatively, and in four cases (66.7%) the same isolate was identified. Cats with a higher end-anaesthetic rectal temperature were significantly less likely to return a positive culture within 3 months (OR 0.398, 95% CI 0.205–0.772; P = 0.006) postsurgery. Cats culturing positive for Escherichia coli at any time point (OR 4.542, 95% CI 1.485–13.89; P = 0.008) were significantly more likely to have their implant removed or replaced.
Conclusions and relevance
Perioperative hypothermia and preoperative positive culture were independent predictors of a postoperative positive culture and this should be taken into consideration when managing these cases. Positive postoperative culture rates were higher than have previously been reported
Long-term survival after multidisciplinary management of resected pancreatic adenocarcinoma.
INTRODUCTION: Actual 5-year survival rates of 10-18% have been reported for patients with resected pancreatic adenocarcinoma (PC), but the use of multimodality therapy was uncommon in these series. We evaluated long-term survival and patterns of recurrence in patients treated for PC with contemporary staging and multimodality therapy.
METHODS: We analyzed 329 consecutive patients with PC evaluated between 1990 and 2002 who underwent resection. Each received a multidisciplinary evaluation and a standard operative approach. Pre- or postoperative chemotherapy and/or chemoradiation were routine. Surgical specimens of 5-year survivors were re-reviewed. A multivariate model of factors associated with long-term survival was constructed.
RESULTS: Patients underwent pancreaticoduodenectomy (n = 302; 92%), distal (n = 20; 6%), or total pancreatectomy (n = 7; 2%). A total of 108 patients (33%) underwent vascular reconstruction, 301 patients (91%) received neoadjuvant or adjuvant therapy, 157 specimens (48%) were node positive, and margins were microscopically positive in 52 patients (16%). Median overall survival and disease-specific survival was 23.9 and 26.5 months. Eighty-eight patients (27%) survived a minimum of 5 years and had a median overall survival of 11 years. Of these, 21 (24%) experienced recurrence, 7 (8%) after 5 years. Late recurrences occurred most frequently in the lungs, the latest at 6.7 years. Multivariate analysis identified disease-negative lymph nodes (P = .02) and no prior attempt at resection (P = 0.01) as associated with 5-year survival.
CONCLUSIONS: Our 27% actual 5-year survival rate for patients with resected PC is superior to that previously reported, and it is influenced by our emphasis on detailed staging and patient selection, a standardized operative approach, and routine use of multimodality therapy

Exercise Training in Pregnancy for obese women (ETIP): study protocol for a randomised controlled trial
<p/> <p>Background</p> <p>Both maternal pre-pregnancy obesity and excessive gestational weight gain are increasing in prevalence and associated with a number of adverse pregnancy outcomes for both mother and child. Observational studies regarding physical activity in pregnancy have found reduced weight gain in active mothers, as well as reduced risk of adverse pregnancy outcomes. There is however a lack of high quality, randomized controlled trials on the effects of regular exercise training in pregnancy, especially those with a pre-pregnancy body mass index (BMI) at or above 30 kg/m<sup>2</sup>.</p> <p>Methods</p> <p>We are conducting a randomised, controlled trial in Norway with two parallel arms; one intervention group and one control group. We will enroll 150 previously sedentary, pregnant women with a pre-pregnancy BMI at or above 30 kg/m<sup>2</sup>. The intervention group will meet for organized exercise training three times per week, starting in gestation week 14 (range 12-16). The control group will get standard antenatal care. The main outcome measure will be weight gain from baseline to delivery. Among the secondary outcome measures are changes in exercise capacity, endothelial function, physical activity level, body composition, serum markers of cardiovascular risk, incontinence, lumbopelvic pain and cardiac function from baseline to gestation week 37 (range 36-38). Offspring outcome measures include anthropometric variables at birth, Apgar score, as well as serum markers of inflammation and metabolism in cord blood.</p> <p>Discussion</p> <p>The results of this trial will provide knowledge about effects of regular exercise training in previously sedentary, obese pregnant women. If the program proves effective in reducing gestational weight gain and adverse pregnancy outcomes, such programs should be considered as part of routine pregnancy care for obese women.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov: <a href="http://www.clinicaltrials.gov/ct2/show/NCT01243554">NCT01243554</a></p
Autologous chondrocyte implantation-derived synovial fluids display distinct responder and non-responder proteomic profiles
Hulme, Charlotte H. & Wilson, Emma L. - Equal contributorsBackground Autologous chondrocyte implantation (ACI) can be used in the treatment of focal cartilage injuries to prevent the onset of osteoarthritis (OA). However, we are yet to understand fully why some individuals do not respond well to this intervention. Identification of a reliable and accurate biomarker panel that can predict which patients are likely to respond well to ACI is needed in order to assign the patient to the most appropriate therapy. This study aimed to compare the baseline and mid-treatment proteomic profiles of synovial fluids (SFs) obtained from responders and non-responders to ACI. Methods SFs were derived from 14 ACI responders (mean Lysholm improvement of 33 (17–54)) and 13 non-responders (mean Lysholm decrease of 14 (4–46)) at the two stages of surgery (cartilage harvest and chondrocyte implantation). Label-free proteome profiling of dynamically compressed SFs was used to identify predictive markers of ACI success or failure and to investigate the biological pathways involved in the clinical response to ACI. Results Only 1 protein displayed a ≥2.0-fold differential abundance in the preclinical SF of ACI responders versus non-responders. However, there is a marked difference between these two groups with regard to their proteome shift in response to cartilage harvest, with 24 and 92 proteins showing ≥2.0-fold differential abundance between Stages I and II in responders and non-responders, respectively. Proteomic data has been uploaded to ProteomeXchange (identifier: PXD005220). We have validated two biologically relevant protein changes associated with this response, demonstrating that matrix metalloproteinase 1 was prominently elevated and S100 calcium binding protein A13 was reduced in response to cartilage harvest in non-responders. Conclusions The differential proteomic response to cartilage harvest noted in responders versus non-responders is completely novel. Our analyses suggest several pathways which appear to be altered in non-responders that are worthy of further investigation to elucidate the mechanisms of ACI failure. These protein changes highlight many putative biomarkers that may have potential for prediction of ACI treatment success
Serum CA 19-9 as a Marker of Resectability and Survival in Patients with Potentially Resectable Pancreatic Cancer Treated with Neoadjuvant Chemoradiation
Purpose
The role of carbohydrate antigen (CA) 19-9 in the evaluation of patients with resectable pancreatic cancer treated with neoadjuvant therapy prior to planned surgical resection is unknown. We evaluated CA 19-9 as a marker of therapeutic response, completion of therapy, and survival in patients enrolled on two recently reported clinical trials.
Patients and Methods
We analyzed patients with radiographically resectable adenocarcinoma of the head/uncinate process treated on two phase II trials of neoadjuvant chemoradiation. Patients without evidence of disease progression following chemoradiation underwent pancreaticoduodenectomy (PD). CA 19-9 was evaluated in patients with a normal bilirubin level.
Results
We enrolled 174 patients, and 119 (68%) completed all therapy including PD. Pretreatment CA 19-9 <37 U/ml had a positive predictive value (PPV) for completing PD of 86% but a negative predictive value (NPV) of 33%. Among patients without evidence of disease at last follow-up, the highest pretreatment CA 19-9 was 1,125 U/ml. Restaging CA 19-9 <61 U/ml had a PPV of 93% and a NPV of 28% for completing PD among resectable patients. The area under the receiver-operating characteristics curve of pretreatment and restaging CA 19-9 levels for completing PD was 0.59 and 0.74, respectively. We identified no association between change in CA 19-9 and histopathologic response (P = 0.74).
Conclusions
Although the PPV of CA 19-9 for completing neoadjuvant therapy and undergoing PD was high, its clinical utility was compromised by a low NPV. Decision-making for patients with resectable PC should remain based on clinical assessment and radiographic staging.PublishedN/
