In what ways does verbal teacher praise and feedback influence students' self-concept and self-efficacy beliefs and their mathematics classroom learning?
Low self-beliefs hinder studentsâ learning (Bong & Skaalvik, 2003) and consequently their life chances (Teach First, 2018). Education is a determining factor of a studentâs future quality of life, and one of the most important subjects in the national curriculum is mathematics (Department of Education, 2021). This present study focuses on the self-beliefs of self-concept and self-efficacy within the mathematics classroom, as both constructs act either to encourage or limit learning (Bong & Skaalvik, 2003). The study explores the influence of increased verbal praise and feedback (VPF) on studentsâ mathematics self-beliefs and whether this influenced their classroom learning, in particular regarding task participation, response to failure, perseverance, and help-seeking. VPF is praise coupled with feedback implemented in a sincere, concise, and task-centred way to help students understand their successes and how to improve in future. A seven-week intervention took place across two lower attaining Year 10 mathematics classes, where teachers increased their use of VPF, aiming to raise student self-beliefs and classroom learning. Data were obtained though questionnaires from all student participants and interviews with eight student participants. The questionnaire data were numerically analysed through descriptive statistics while interview data were thematically coded. The study found that increased VPF positively influenced studentsâ self-concept and self-efficacy, with self-efficacy displaying the greatest shift and thus indicating greater malleability than self-concept. Mathematics classroom learning was particularly influenced within the themes of response to failure and perseverance, both demonstrating the greatest positive shifts. Thus, increased VPF helped raise studentsâ self-beliefs which positively influenced their mathematics learning. Consequently teachers could consider implementing VPF within their everyday practice to help support studentsâ self-beliefs and mathematics learning
Rapid sequence induction of anaesthesia in UK emergency departments: A national census
Introduction: Rapid sequence induction of anaesthesia and tracheal intubation (RSI) is an integral part of modern emergency care. Previously, emergency department (ED) RSI has been provided by anaesthetists, but UK emergency physicians are increasingly developing this skill. We undertook a 2-week census of ED RSI to establish a baseline of current practice. Methods: All 115 UK College of Emergency Medicine airway leads were contacted and asked to return anonymised data on every drug-assisted intubation occurring in their ED during a 2-week period in September 2008. The number of RSIs and also the total number of ED attendances during the same period were requested. Results: Complete data were returned from 64 EDs (56%). The total number of patients undergoing RSI was 218, with an incidence of 0.12%, or approximately one in every 800 ED attendances. Anaesthetic staff undertook 80% of ED RSIs, predominantly senior anaesthetic trainees of specialist trainee year 3 (ST3) or above. During normal office hours 74% of these anaesthetic trainees were supervised during the procedure, with a significant fall in supervision rates to 15% outside normal office hours (
Using card games to study cultural differences in menâs social talk about prostate cancer
Aim
To report the Card Games approach used to study men's talk about their risk for prostate cancer and as a method of data collection to analyse patterns of talk among distinct cultural groups.
Design
A constructivist grounded theory approach using focus groups to analyse men's social talk about prostate cancer.
Methods
Data were collected using three focus groups with AfricanâCaribbean, Somali, and White British men. The focus groups were conducted in a location of the men's choice with a focus group facilitator and observer. Four Card Games were given to the men to encourage social talk.
Results
The AfricanâCaribbean men had the most democratic talk with the use of agreement and disagreement and the Somali men were the most inclusive of others and used the most humour. The White British men were competitive in their talk and the least inclusive of each other's views.
Conclusion
The Card Games revealed differences in the pattern of talk, which provided insight into how men may use social talk to develop their understanding of prostate cancer risk. This is useful for healthcare professionals as it provides a grounding for structuring discussions with men about prostate cancer, while understanding of how riskârelated knowledge may be reconstructed in social talk and interactions.
Impact
The methodology discussed in this paper addressed the use of focus group to analyse talk of men from culturally diverse groups. The use of Card Games allowed the talk between the men to take centre stage and this allowed differences in the social talk of the men to become apparent. The use of this methodology could have an impact on approaches to researching cultural understandings of cancer risk, which may provide evidence on effective delivery of sociocultural relevant health education relating to cancer screening
âWeâre talking about black men here, thereâs a differenceâ Cultural differences in socialised knowledge of prostate cancer risk: a qualitative research study
Purpose: To detail social knowledge of prostate cancer risk amongst cultural groups. Prostate cancer is the most common cancer in men, and black men are at the highest risk. Despite this, black men are the least likely to be diagnosed early with prostate cancer. It is importance to understand why this is so that these men can receive early access to effective treatment and support.
Methods: A constructivist grounded theory methodology was used. Data were collected between December 2015 and October 2017; seventeen men were interviewed, and eighteen men took part in focus groups.
Results: There were differences in the way the men constructed their understanding of risks for prostate cancer. The social construction of prostate cancer risk knowledge was mediated by the way the men were socialised to understand and accept this risk. The Somali and African Caribbean men placed social importance on the healthy body, whereas the white working class men seemed to find social value through the unwell body. This research proposes the theory that social constructions of knowledge mediate the way men perceive and accept their risk for prostate cancer.
Conclusion: Understanding socialised knowledge of risk may mediate the acceptance of specific prostate cancer risks. This knowledge may help health providers and third sector organisations produce targeted health-related information. Health practitioners may also benefit from understanding how socially constructed ideas of the body could influence the way men respond to conversations about prostate cancer so that tailored and culturally appropriate support can be offered
ACTIVE: a randomised feasibility trial of a behavioural intervention to reduce fatigue in women undergoing radiotherapy for early breast cancer: study protocol
Background
Fatigue is rated as the most distressing side effect of radiotherapy treatment for curable breast cancer. About four in ten women treated experience fatigue, which can last for years after treatment. The impact of this debilitating tiredness is loss of independence and impaired physical and mental function. Our study will take a behavioural intervention with demonstrated effect in treating fatigue in a mixed group of chemotherapy patients and adapt it for women undergoing radiotherapy for early breast cancer. The purpose of this trial is to evaluate the feasibility of delivering the intervention in the radiotherapy pathway for patients at a high risk of fatigue and to explore participantsâ experiences of the trial and intervention.
Methods
A pragmatic single-site non-blinded feasibility trial of a behavioural intervention. Main inclusion criteria are prescription of the UK standard 40 Gy in 15 fractions over 3 weeks of radiotherapy (± tumour bed boost) for early (stage 0âIIIa) breast cancer. The total projected sample size after attrition is 70. A previously developed fatigue risk score tool will be used to predict individualâs likelihood of experiencing fatigue. Thirty women predicted to be at a high risk of experiencing significant fatigue will be allocated in the ratio 2:1 to the behavioural intervention or education trial arms, respectively. These feasibility trial participants will be assessed at baseline, after 10 and 15 fractions of radiotherapy and 10 days, 3 weeks and 6 months after radiotherapy. A further 40 women predicted to be at a lower risk of fatigue will join a risk score validation group.
Measures to assess feasibility include recruitment, retention and completion rates and variation in implementation of the intervention. Process evaluation with intervention providers and users includes fidelity and adherence checks and qualitative interviews to understand how changes in behaviour are initiated and sustained.
Discussion
This feasibility study collates data to both inform the progression to and design of a future definitive trial and to refine the intervention
JMJD5 is a human arginyl C-3 hydroxylase.
Oxygenase-catalysed post-translational modifications of basic protein residues, including lysyl hydroxylations and NΔ-methyl lysyl demethylations, have important cellular roles. Jumonji-C (JmjC) domain-containing protein 5 (JMJD5), which genetic studies reveal is essential in animal development, is reported as a histone NΔ-methyl lysine demethylase (KDM). Here we report how extensive screening with peptides based on JMJD5 interacting proteins led to the finding that JMJD5 catalyses stereoselective C-3 hydroxylation of arginine residues in sequences from human regulator of chromosome condensation domain-containing protein 1 (RCCD1) and ribosomal protein S6 (RPS6). High-resolution crystallographic analyses reveal overall fold, active site and substrate binding/product release features supporting the assignment of JMJD5 as an arginine hydroxylase rather than a KDM. The results will be useful in the development of selective oxygenase inhibitors for the treatment of cancer and genetic diseases
Designing and implementing a COPD discharge care bundle
National surveys have revealed significant differences in patient outcomes following admission to hospital with acute exacerbation of COPD which are likely to be due to variations in care. We developed a care bundle, comprising a short list of evidence-based practices to be implemented prior to discharge for all patients admitted with this condition, based on a review of national guidelines and other relevant literature, expert opinion and patient consultation. Implementation was then piloted using action research methodologies with patient input. Actively involving staff was vital to ensure that the changes introduced were understood and the process followed. Implementation of a care bundle has the potential to produce a dramatic improvement in compliance with optimum health care practice
Chromium-based bcc-superalloys strengthened by iron supplements
Chromium alloys are being considered for next-generation concentrated solar power applications operating > 800 °C. Cr offers advantages in melting point, cost, and oxidation resistance. However, improvements in mechanical performance are needed. Here, Cr-based body-centred-cubic (bcc) alloys of the type Cr(Fe)-NiAl are investigated, leading to âbcc-superalloysâ comprising a bcc-Cr(Fe) matrix (ÎČ) strengthened by ordered-bcc NiAl intermetallic precipitates (ÎČâ), with iron additions to tailor the precipitate volume fraction and mechanical properties at high temperatures. Computational design using CALculation of PHAse Diagram (CALPHAD) predicts that Fe increases the solubility of Ni and Al, increasing precipitate volume fraction, which is validated experimentally. Nano-scale, highly-coherent B2-NiAl precipitates with lattice misfit ⌠0.1% are formed in the Cr(Fe) matrix. The Cr(Fe)-NiAl A2-B2 alloys show remarkably low coarsening rate (âŒ102 nm3/h at 1000 °C), outperforming ferritic-superalloys, cobalt- and nickel-based superalloys. Low interfacial energies of ⌠40/20 mJ/m2 at 1000/1200 °C are determined based on the coarsening kinetics. The low coarsening rates are principally attributed to the low solubility of Ni and Al in the Cr matrix. The alloys show high compressive yield strength of âŒ320 MPa at 1000 °C. The Fe-modified alloy exhibits resistance to age softening, related to the low coarsening rate as well as the relatively stable Orowan strengthening as a function of precipitate radius. Microstructure tailoring with Fe additions offers a new design route to improve the balance of properties in âCr-superalloysâ, accelerating their development as a new class of high-temperature materials
