Assessing a Monitoring Scale of Physiological Health and Risk Assessment Among Those Exposed to Heated Environments: A Brief Report

Background: Prevention of heat illness is of considerable medical interest within the field of occupational work. There are many established methods of perceptual health assessment; however, many are rather unpractical and timely. The objective was to improve the practicality and timeliness of perceptual physiological monitoring; a Heat Thermal Sensation scale has been developed. The usefulness of the scale was assessed on its ability to monitor physiological variable. Materials and Methods: Ten apparently healthy individuals performed physically exerting activity while exposed to 37 °C. Sensation and physiology were measured throughout. Results: The perceptual monitoring scale demonstrated weak positive correlations with human physiological variables including cardiorespiratory stresses. It demonstrated no correlation with thermoregulation stress. Conclusion: The scale needs further development to better improve heat illness practices to those commonly exposed in extreme heat during occupational work

Crossing borders: new teachers co-constructing professional identity in performative times

This paper draws on a range of theoretical perspectives on the construction of new teachers’ professional identity. It focuses particularly on the impact of the development in many national education systems of a performative culture of the management and regulation of teachers’ work. Whilst the role of interactions with professional colleagues and school managers in the performative school has been extensively researched, less attention has been paid to new teachers’ interactions with students. This paper highlights the need for further research focusing on the process of identity co-construction with students. A key theoretical concept employed is that of liminality, the space within which identities are in transition as teachers adjust to the culture of a new professional workplace, and the nature of the engagement of new teachers, or teachers who change schools, with students. The authors argue that an investigation into the processes of this co-construction of identity offers scope for new insights into the extent to which teachers might construct either a teacher identity at odds with their personal and professional values, or a more ‘authentic’ identity that counters performative discourses. These insights will in turn add to our understanding of the complex range of factors impacting on teacher resilience and motivation

The non-equivalent circulant D-optimal designs for n = 90

An exhaustive search was carried out to find all 1358 non-equivalent circulant D-optimal designs for n = 90. A sample of 30 of these designs, presented in a table in the form of the corresponding non-equivalent supplementary difference sets, is given. All these designs are new, except one found by J.H.E. Cohn (Bull. London Math. Soc. 21 (1989), 36-42)

The Nonequivalent Circulant D-Optimal Designs for n=2 mod 4, n<=54, n=66

AbstractAll non-equivalent circulant D-optimal designs for n ≡ 2 mod 4, n ⩽ 54 and n = 66 are given and were found by an exhaustive search. There is a unique non-equivalent circulant design for each value of n ⩽ 18, 3 for n = 26 and n = 30, 8 for n = 38, 31 for n = 42, 17 for n = 46, 39 for n = 50, 48 for n = 54, and 1025 for n = 66. These are presented in tables in the form of the corresponding non-equivalent supplementary difference sets. Most of the given designs are new

Liver Transplantation for Pediatric Hepatocellular Carcinoma: A Systematic Review

Liver transplantation (LT) is the only potentially curative option for children with unresectable hepatocellular carcinoma (HCC). We performed a systematic review of the MEDLINE, Scopus, Cochrane Library, and Web of Science databases (end-of-search date: 31 July 2020). Our outcomes were overall survival (OS) and disease-free survival (DFS). We evaluated the effect of clinically relevant variables on outcomes using the Kaplan&ndash;Meier method and log-rank test. Sixty-seven studies reporting on 245 children undergoing LT for HCC were included. DFS data were available for 150 patients and the 1-, 3-, and 5-year DFS rates were 92.3%, 89.1%, and 84.5%, respectively. Sixty of the two hundred and thirty-eight patients (25.2%) died over a mean follow up of 46.8 &plusmn; 47.4 months. OS data were available for 222 patients and the 1-, 3-, and 5-year OS rates were 87.9%, 78.8%, and 74.3%, respectively. Although no difference was observed between children transplanted within vs. beyond Milan criteria (p = 0.15), superior OS was observed in children transplanted within vs. beyond UCSF criteria (p = 0.02). LT can yield favorable outcomes for pediatric HCC beyond Milan but not beyond UCSF criteria. Further research is required to determine appropriate LT selection criteria for pediatric HCC
