Estimates of the number of people in England who attain or exceed vigorous intensity exercise by walking at 3 mph

Walking is a safe, accessible and low cost activity, amenable to change and known to have great potential to increase physical activity levels in sedentary individuals. The objective of this study is to estimate the proportion of the 2009 adult population of England who would attain or exceed vigorous intensity activity (>70% maximum heart rate [HR(max)]) by walking at 3 mph. We conducted predictive impact modelling using participants' (n = 1741, aged 25-64 years) cardiovascular fitness data from treadmill walking tests. We combined this data with English population estimates adjusted for age and sex to estimate the numbers of individuals that would exceed 70% HR(max) (an intensity considered sufficient for fitness gains) when walking at 3 mph (4.8 km · h(-1)). We estimate 1.5 million men (95% confidence interval [CI] 0.9-2.2 million) (from 13.4 million corresponding to 11.6% (95% CI 7.0-16.2%)) and 3.9 million women (95% CI 3.0-4.8 million) (from 13.6 million corresponding to 28.6% (95% CI 22.0-35.1%)) in England aged 25-64 years would benefit from regularly walking at 3 mph. In total, a projected 5.4 million individuals (95% CI 3.9-6.9 million) aged 25-64 (from 26.97 million corresponding to 20.1% (95% CI 14.6-25.7%)) could benefit from walking at 3 mph. Our estimates suggest a considerable number of individuals in the English population could receive fitness and health benefits by walking regularly at 3 mph. Physical activity messages that promote walking at this speed may therefore have the potential to significantly impact national fitness levels and health in England.     

Three-Year-Olds'' Problems with False Belief: Conceptual Deficit or Linguistic Artifact?

Researchers are divided over whether young children understand other people's minds. This study reexamines the main technique used to show a basic inability in 3-year-olds to make judgments about a person's thoughts when that person's knowledge happens to be false. 131 children, aged 3, 3 1/2, and 4, were shown the real, unexpected contents of a chocolate box and were required to say what a friend would think was in it and what their own previous expectations had been. Success in this task was compared between the 3 age groups and also according to the specificity of questions asked. It was found, in contrast to previous findings, that test questions that are temporally specific and syntactically straightforward enable most 3-year-olds to attribute false beliefs to others. These results suggest that 3-year-olds' access to information about others' mental states is bounded by the linguistic demands placed upon them, but long before their fourth birthday children have some understanding of others' mind.     

Working in Creative Partnership with Students to Co-Produce Neuroanatomy e-Learning Resources in a New Era of Blended Learning

Anatomists are well placed to tackle the transition from face-to-face to blended learning approaches as a result of the rapidly forced changes brought about by Covid-19. The subject is extremely visual and has, therefore, previously been a target for the development of technology-enhanced learning initiatives over the last ten years. Today's students have come to expect the integration of technology in the classroom and remotely. They adjust quickly to the innovative use of new applications and software and have begun to integrate it within their own workflow for note taking and study aids. Given the intense drive toward blended deliveries of anatomy as a result of the Covid-19 pandemic, it is easy to picture how the benefits of working in partnership with students (in order to achieve many of these aims) would be possible, particularly in difficult subjects like neuroanatomy. In doing so, it provides anatomists with new opportunities to engage students in a way that aligns well with best practice frameworks for engaging students through partnership. The current United Kingdom guidelines set out by Advance HE (a professional membership organization for promoting excellence in higher education) strongly encourages the higher education community to seek out appropriate academic contexts where a balance of power can be struck between staff and student to create a community of practice. If such an approach can be fully embraced by anatomists, a strong argument can be made for seizing the opportunity to optimize the benefits of student partnership work in this discipline.     

Positive narratives: the stories young people with Social,Emotional and Behavioural Difficulties (SEBD) tell about their futures

This research drew on positive psychology in order to offer an optimistic way of conceptualising the lives of young people who are often described as having ‘SEBD’ (social, emotional and behavioural difficulties), now SEMH (social, emotional, mental health) in the English 2014 Special Educational Needs and Disability (SEND) Code of Practice. Positive psychology places emphasis on: the future, strengths, resources and potential, and suggests that negative experiences can build positive qualities. The young people in this research identified a range of strengths and resources in their lives that they had built as a result of earlier negative experiences. Narrative Oriented Inquiry (NOI) was used to analyse the themes of potential and growth in their stories which reveal their hopes and aspirations for the future. By giving these young people the opportunity to tell their stories this research permitted them to focus on where they were going, rather than where they had been.

Becoming Mobile: Reference in the Ubiquitous Library

ABSTRACT

Library patrons are adopting mobile devices for personal and other uses. The ubiquity of mobile devices will lead to changes in how and where learning and education happens. Libraries have wanted to become ubiquitous by making resources and services available anywhere, anytime. Reference librarians can use mobile devices and applications to include services in mobile learning environments. Challenges to libraries include uncertainty about which technologies to adopt in a rapidly changing technology landscape, the cost of technology adoption, staffing for 24–7, diversity of needs and preferences among library patrons, and the need to offer stable, consistent services. The combination of mobile librarians, mobile patrons, and mobile content provides an opportunity to move closer to the ideal of the ubiquitous library.

Tables for Transmutation of orders of Merit into Normal Equivalents

Reliability coefficients of linear combinations of observed scores have anomalous properties which have led to persistent difficulties in the investigation of difference scores and gain scores in test theory. Interpretation of these test scores is further complicated by effects of correlated errors of measurement which are likely to appear in difference scores and gain scores in practice. In this paper the discrepancies between classical results and correct results obtained from more general formulas, which allow for correlated errors, are examined systematically. These discrepancies depend strongly on the reliability coefficients of the respective tests and are smallest when the influence of the variables related by the formulas is least. A vector representation of difference scores reveals that these anomalies arise from simple geometric relations among observed scores, true scores, and error scores inherent in the test-theory model. In this context, doubts as to the usefulness of difference scores and gain scores in testing practice expressed by previous authors appear to be justified.     

Activities and Attitudes of Retired University Staff

A national sample of 1662 academic and academic related university staff, who had retired 3-5 years earlier, completed a postal survey about their current employment, research, other academic activities, and the academic resources available to them, and about their attitudes to retirement, and the extent of their leisure, voluntary, and other caring activities. Over two-thirds of academics and four-fifths of academic related staff had retired early. Younger staff were more often currently employed, but the employment rate amongst academics aged 66-73 was very much greater than in the general population. The extent of research and other academic activities was related to university rank rather than age, with professors and readers more committed, and less involved in leisure activities. The most frequent reasons for early retirement were dissatisfaction with changes in the universities and financial inducements. The majority said they were more contented because of retiring, and most would not have wanted to retire later than they did, but concerns were expressed about the failure of universities to give adequate status and resources to retired academics. There was some evidence that women were discriminated against in retirement.     

Digital ITEMS Module 1: Reliability in Classical Test Theory

In this ITEMS module, we provide a two‐part introduction to the topic of reliability from the perspective of classical test theory (CTT). In the first part, which is directed primarily at beginning learners, we review and build on the content presented in the original didactic ITEMS article by Traub and Rowley (1991). Specifically, we discuss the notion of reliability as an intuitive everyday concept to lay the foundation for its formalization as a reliability coefficient via the basic CTT model. We then walk through the step‐by‐step computation of key reliability indices and discuss the data collection conditions under which each is most suitable. In the second part, which is directed primarily at intermediary learners, we present a distribution‐centered perspective on the same content. We discuss the associated assumptions of various CTT models ranging from parallel to congeneric, and review how these affect the choice of reliability statistics. Throughout the module, we use a customized Excel workbook with sample data and basic data manipulation functionalities to illustrate the computation of individual statistics and to allow for structured independent exploration. In addition, we provide quiz questions with diagnostic feedback as well as short videos that walk through sample exercises within the workbook.     

Patterns of preschool provision in English local authorities 1

It is estimated that in 1986 40‐50% of children in England aged 3 and 4 were attending pre‐school playgroups. Another 20% were receiving education in nursery schools and classes, mostly part time, whilst a further 20% were in the reception classes of infant schools, mostly full time. Using data on the provision of these services within each local authority in England it is shown that the numbers of nursery education and of playgroup places are strongly negatively correlated. Combining these statistics with data from the 1981 Census it is also shown that the rates of provision are strongly related to the socio‐economic characteristics of the authorities, such that playgroups predominate in the more affluent areas whereas high levels of nursery education are found in urban areas with more material disadvantage.
