Exploring gifted primary students' perceptions of the characteristics of their effective teachers

This study sought to explore the question of what personal and professional characteristics may be particularly relevant to effective teachers of the gifted, by investigating the characteristics of effective teachers identified in both the general teacher effectiveness literature and the gifted education literature, through the perceptions of gifted primary students about teachers they regarded as effective. A questionnaire was created for this study, comprised of items which represented characteristics identified from the literature review and determined to be relevant to students' experiences. This questionnaire was distributed to the sample of intellectually gifted primary students (n = 168), and their responses were examined for differences between moderately gifted (n = 74) and highly gifted primary students (n = 94), as well as female (n = 84) and male (n = 81) gifted primary students. This study also recorded gifted primary students' opinions regarding what they believe were the characteristics that made their nominated teachers so effective, through the use of an open-ended question in the questionnaire. This study found that the characteristics of effective teachers identified in both the general teacher effectiveness and the gifted education literatures were supported by gifted primary students' perceptions of their nominated teachers. This study also found differences between moderately gifted and highly gifted primary students, as well as gender differences on a number of characteristics. These differences support the need to examine, more carefully, teacher behaviour and strategies in the classroom for differences in how they may influence the learning of students of different levels of ability and gender. A qualitative analysis of gifted primary students' answers to the open-ended question also revealed in-depth information about how teachers' characteristics are related to each other, and how students perceive them to be effective, as well as suggesting characteristics that were not identified in the previous review of the literature

Should I stay or should I go? Patient understandings of and responses to source-isolation practices

Isolation of patients, who are colonised or infected with a multidrug-resistant organism (source-isolation), is a common practice in most acute health-care settings, to prevent transmission to other patients. Efforts to improve the efficacy of source-isolation in hospitals focus on healthcare staff compliance with isolation precautions. In this article we examine patients’ awareness, understandings and observance of source-isolation practices and directives with a view to understanding better the roles patients play or could play in transmitting, or limiting transmission, of multidrug-resistant organisms (MRO). Seventeen source-isolated adult surgical patients and two relatives participated in video-reflexive ethnography and interviews. We learned that, although most of these patients wanted to protect themselves and others from colonisation/infection with a MRO, they had a limited understanding of what precautions they could take while in isolation and found it difficult to obtain ongoing information. Thus, many patients regularly left their source-isolation rooms without taking appropriate precautions and were potentially contributing to environmental contamination and transmission. Some patients also interacted with other patients and their personal belongings in ways that exposed other patients, unnecessarily, to colonisation/infection risk. By not providing patients with adequate information on infection risk or how they could contribute to their own safety or that of others, they are denied the opportunity to fully engage in their healthcare. To improve the efficacy of source-isolation and contact precautions in general, patient care providers should consider colonised or infected patients as active partners in reducing transmission and involve patients and relatives in regular, ongoing conversations about transmission prevention

Does or did the supernova remnant Cassiopeia A operate as a PeVatron?

For decades, supernova remnants (SNRs) have been considered the prime sources of Galactic Cosmic rays (CRs). But whether SNRs can accelerate CR protons to PeV energies and thus dominate CR flux up to the knee is currently under intensive theoretical and phenomenological debate. The direct test of the ability of SNRs to operate as CR PeVatrons can be provided by ultrahigh-energy (UHE; $E_\gamma \geq 100$~TeV) $\gamma$-rays. In this context, the historical SNR Cassiopeia A (Cas A) is considered one of the most promising target for UHE observations. This paper presents the observation of Cas A and its vicinity by the LHAASO KM2A detector. The exceptional sensitivity of LHAASO KM2A in the UHE band, combined with the young age of Cas A, enabled us to derive stringent model-independent limits on the energy budget of UHE protons and nuclei accelerated by Cas A at any epoch after the explosion. The results challenge the prevailing paradigm that Cas A-type SNRs are major suppliers of PeV CRs in the Milky Way.Comment: 11 pages, 3 figures, Accepted by the APJ

Measurement of ultra-high-energy diffuse gamma-ray emission of the Galactic plane from 10 TeV to 1 PeV with LHAASO-KM2A

The diffuse Galactic $\gamma$-ray emission, mainly produced via interactions between cosmic rays and the interstellar medium and/or radiation field, is a very important probe of the distribution, propagation, and interaction of cosmic rays in the Milky Way. In this work we report the measurements of diffuse $\gamma$-rays from the Galactic plane between 10 TeV and 1 PeV energies, with the square kilometer array of the Large High Altitude Air Shower Observatory (LHAASO). Diffuse emissions from the inner ($15^{\circ}<l<125^{\circ}$, $|b|<5^{\circ}$) and outer ($125^{\circ}<l<235^{\circ}$, $|b|<5^{\circ}$) Galactic plane are detected with $29.1\sigma$ and $12.7\sigma$ significance, respectively. The outer Galactic plane diffuse emission is detected for the first time in the very- to ultra-high-energy domain ($E>10$~TeV). The energy spectrum in the inner Galaxy regions can be described by a power-law function with an index of $-2.99\pm0.04$, which is different from the curved spectrum as expected from hadronic interactions between locally measured cosmic rays and the line-of-sight integrated gas content. Furthermore, the measured flux is higher by a factor of $\sim3$ than the prediction. A similar spectrum with an index of $-2.99\pm0.07$ is found in the outer Galaxy region, and the absolute flux for $10\lesssim E\lesssim60$ TeV is again higher than the prediction for hadronic cosmic ray interactions. The latitude distributions of the diffuse emission are consistent with the gas distribution, while the longitude distributions show clear deviation from the gas distribution. The LHAASO measurements imply that either additional emission sources exist or cosmic ray intensities have spatial variations.Comment: 12 pages, 8 figures, 5 tables; accepted for publication in Physical Review Letters; source mask file provided as ancillary fil

Real-time Monitoring for the Next Core-Collapse Supernova in JUNO

Core-collapse supernova (CCSN) is one of the most energetic astrophysical events in the Universe. The early and prompt detection of neutrinos before (pre-SN) and during the SN burst is a unique opportunity to realize the multi-messenger observation of the CCSN events. In this work, we describe the monitoring concept and present the sensitivity of the system to the pre-SN and SN neutrinos at the Jiangmen Underground Neutrino Observatory (JUNO), which is a 20 kton liquid scintillator detector under construction in South China. The real-time monitoring system is designed with both the prompt monitors on the electronic board and online monitors at the data acquisition stage, in order to ensure both the alert speed and alert coverage of progenitor stars. By assuming a false alert rate of 1 per year, this monitoring system can be sensitive to the pre-SN neutrinos up to the distance of about 1.6 (0.9) kpc and SN neutrinos up to about 370 (360) kpc for a progenitor mass of 30$M_{\odot}$ for the case of normal (inverted) mass ordering. The pointing ability of the CCSN is evaluated by using the accumulated event anisotropy of the inverse beta decay interactions from pre-SN or SN neutrinos, which, along with the early alert, can play important roles for the followup multi-messenger observations of the next Galactic or nearby extragalactic CCSN.Comment: 24 pages, 9 figure

Relationship between patient safety culture and patient experience in hospital settings: a scoping review protocol

Introduction Hospitals commonly examine patient safety culture and other quality indicators to evaluate and improve performance in relation to quality and safety. A growing body of research has separately examined relationships between patient safety culture and patient experience on clinical outcomes and other quality indicators. However, there is a knowledge gap regarding the relationship between these two important domains. This article describes the protocol for a scoping review of published literature examining the relationship between patient safety culture and patient experience in hospital settings. The scoping review will provide an overview of research into the relationship between patient safety culture and patient experience in hospital contexts, map key concepts underpinning these domains and identify research gaps for further study.Methods and analysis The scoping review will be conducted using the five stages of Arksey and O’Malley’s framework: identify the research question; identify relevant studies; study selection; chart data; and collate, summarise and report the results. The inclusion criteria will be applied using the Population, Concept and Context Framework. Searches will be conducted in the CINAHL, Cochrane Library, ProQuest, MEDLINE, PsycINFO, Scopus and SciELO databases, without applying date range limits. Hand-searching of grey literature will also be performed to find relevant, non-indexed literature. Data will be extracted using a standardised data extraction form developed by the Joanna Briggs Institute. Both descriptive and thematic analyses will be undertaken to scope key concepts within the body of reviewed literature.Ethics and dissemination This type of study does not require an ethics review. The results will be submitted for publication in a peer-reviewed journal and presented at conferences

To follow a rule?:On frontline clinicians’ understandings and embodiments of hospital-acquired infection prevention and control rules

This article reports on a study of clinicians’ responses to footage of their enactments of infection prevention and control. The study’s approach was to elicit clinicians’ reflections on and clarifications about the connections among infection control activities and infection control rules, taking into account their awareness, interpretation, and in situ application of those rules. The findings of the study are that clinicians responded to footage of their own IPC practices by articulating previously unheeded tensions and constraints including: infection control rules that were incomplete, undergoing change, and conflicting; material obstructions limiting infection control efforts; and habituated and divergent rule enactments and rule interpretations that were problematic but disregarded. The reflexive process is shown to elicit clinicians’ learning about these complexities as they affect the accomplishment of effective infection control. The process is further shown to strengthen clinicians’ appreciation of infection control as necessitating deliberation to decide what are locally appropriate standards, interpretations, assumptions, habituations and enactments of infection control. The article concludes that clinicians’ ‘practical wisdom’ is unlikely to reach its full potential without video-assisted scrutiny of and deliberation about in situ clinical work. This enables clinicians to anchor their in situ enactments, reasonings and interpretations to local agreements about the intent, applicability, limits and practical enactment of rules. Key words: video-reflexivity, rules, infection control, patient safety, embodied practice, practical wisdom, abductio

Australian community pharmacy service provision factors, stresses and strains: A qualitative study

Introduction: Despite the desire of pharmacists to provide new and more clinically focused services, strain on the community pharmacist workforce is a known barrier to their service provision. Causes are unclear, although the impact of increased workload, as well as broader role-related and systemic causes have been suggested. Aims: To (1) explore the role strain, stress and systemic factors affecting Australian community pharmacists' provision of cognitive pharmacy services (CPS), using the Community Pharmacist Role Stress Factor Framework (CPRSFF), and (2) adapt the CPRSFF to the local setting. Methods: Semi-structured interviews were conducted with Australian community pharmacists. Transcripts were analysed with the framework method to verify and adapt the CPRSFF. Thematic analysis of particular codes identified personal outcomes and causative patterns in perceived workforce strain. Results: Twenty-three registered pharmacists across Australia were interviewed. CPS role benefits included: helping people, and increased competency, performance, pharmacy financial return, recognition from the public and other health professionals, and satisfaction. However, strain was worsened by organisational expectations, unsupportive management and insufficient resources. This could result in pharmacist dissatisfaction and turnover in jobs, sector or careers. Two additional factors, workflow and service quality, were added to the framework. One factor, “View of career importance versus partner's career”, was not apparent. Conclusion: The CPRSFF was found to be valuable in exploring the pharmacist role system and analysing workforce strain. Pharmacists weighed up positive and negative outcomes of work tasks, jobs and roles to decide task priority and personal job significance. Supportive pharmacy environments enabled pharmacists to provide CPS, which increased workplace and career embeddedness. However, workplace culture at odds with professional pharmacist values resulted in job dissatisfaction and staff turnover

Medical interns' reflections on their training in use of personal protective equipment

BACKGROUND: The current COVID-19 pandemic has demonstrated that personal protective equipment (PPE) is essential, to prevent the acquisition and transmission of infectious diseases, yet its use is often sub-optimal in the clinical setting. Training and education are important to ensure and sustain the safe and effective use of PPE by medical interns, but current methods are often inadequate in providing the relevant knowledge and skills. The purpose of this study was to explore medical graduates' experiences of the use of PPE and identify opportunities for improvement in education and training programmes, to improve occupational and patient safety. METHODS: This study was undertaken in 2018 in a large tertiary-care teaching hospital in Sydney, Australia, to explore medical interns' self-reported experiences of PPE use, at the beginning of their internship. Reflexive groups were conducted immediately after theoretical and practical PPE training, during hospital orientation. Transcripts of recorded discussions were analysed, using a thematic approach that drew on the COM-B (capability, opportunity, motivation - behaviour) framework for behaviour. RESULTS: 80% of 90 eligible graduates participated. Many interns had not previously received formal training in the specific skills required for optimal PPE use and had developed potentially unsafe habits. Their experiences as medical students in clinical areas contrasted sharply with recommended practice taught at hospital orientation and impacted on their ability to cultivate correct PPE use. CONCLUSIONS: Undergraduate teaching should be consistent with best practice PPE use, and include practical training that embeds correct and safe practices
