Bedrest in healthy women: Effects of menstrual function and oral contraceptives
With the development of the space shuttle program, space flight for the first time is available to individuals who have not been specially selected and trained to be astronauts. In addition, women are being actively recruited into the space program, both as mission specialists and as career astronauts. One purpose of this project was to examine some of the physiological responses of women to a simulated weightlessness program (12 day horizontal bedrest), to compare their responses to those reported in men during similar programs, and to test whether menstrual function might alter some of the physiological changes which occur during bedrest, specifically changes in the plasma volume, exercise tolerance, and venous compliance before and after bedrest
Technology education in South Africa: an evaluation of the impact of an experimental high school curriculum with particular reference to teacher pedagogy and student group work
This paper focuses on the impact of the Technology Education Project in the North West Province of South Africa (NWPTEP) which has aimed to introduce technology education into a group of the Province's high schools, in grades 10 - 12. It reports on an evaluation study carried out in the final stages of the project, looking particularly at the impact of introducing an active, learner centred, problem solving pedagogy into the schools and within this at the effect of using group work in the teaching and learning situation. The paper presents findings derived from the assessment of a pupil technological activity, an evaluation questionnaire and a set of structured interviews with those involved in the project
Absolute rigidity spectrum of protons and helium nuclei above 10 GV/c
Proton and helium nuclei differential spectra were gathered with a balloon borne magnet spectrometer. The data were fitted to the assumption that the differential flux can be represented by a power law in rigidity. In the rigidity range 10 to 25 GV/c the spectral indices were found to be -(2.74 plus or minus 0.04) for protons and -(2.71 plus or minus 0.05) for helium nuclei. A brief discussion is given by systematic errors
Signature pedagogies for designing: A speculative framework for supporting learning and teaching in Design and Technology education
Tunable critical field in Rashba superconductor thin-films
The upper critical field in type II superconductors is limited by the Pauli
paramagnetic limit. In superconductors with strong Rashba spin-orbit coupling
this limit can be overcome by forming a helical state. Here we quantitatively
study the magnetic field-temperature phase diagram of finite-size
superconductors with Rashba spin-orbit coupling. We discuss the effect of
finite size and shape anisotropy. We demonstrate that the critical field is
controllable by intrinsic parameters such as spin-orbit coupling strength and
tunable parameters such as sample geometry and applied field direction. Our
study opens new avenues for the design of superconducting spin-valves.Comment: 5 pages, 4 figures, supplemental material
Informal carers' experiences of caring for a person with heart failure in a community setting
Heart failure (HF) is a life limiting condition with a poor prognosis and unpredictable disease trajectory. HF brings physical and emotional challenges for patients and their carers. Predominantly the informal carer population consists of older females, however, caring is evolving as longevity increases
and complex conditions are become more commonplace. Consequently, more men and younger people are contributing to daily care. The aim of this study was to explore the positive as well as negative dimensions of caring in HF across a range of carer characteristics Fourteen semi-structured interviews
were conducted with informal carers of people with HF in the UK (median age 71; female 10). Interviews were transcribed verbatim and analysed with the assistance of NVivo10 using Interpretative Phenomenological Analysis. Findings from the study demonstrated that most participants considered caring
as integral to their relationships. Dimensions facilitating positivity in caring included compassion, thoughtfulness and understanding. An ability to cope was influenced by a range of attributes including quality of relationships in the carer/patient dyad and with formal social care providers who offered access to tailored and timely information and support. The unpredictable HF disease trajectory influenced the carer experience and enhanced the challenges encountered. The information needs of carers were not always adequately met
and younger adult carers expressed particular difficulties with appropriate information and support. Expectations of our informal carer population are increasing and evolving. Health and social care policy requires innovative proposals for the funding and delivery of health and social care that has the
contribution made by informal carers at its core
Parents’ experiences of caring for a young child with type 1 diabetes: a systematic review and synthesis of qualitative evidence
Abstract: Aims: To synthesise the qualitative evidence on parents’ experiences of caring for a child aged ≤8 years with type 1 diabetes to identify: the challenges they encounter; their views about support received; ways in which support could be improved; and, directions for future research. Methods: We searched Medline, EMBASE, CINAHL, PsycINFO and Web of Science databases to identify qualitative studies reporting parents’ views and experiences of caring for a child with type 1 diabetes aged ≤8 years. Key analytical themes were identified using thematic synthesis. Results: Fourteen studies were included. The synthesis resulted in the generation of two overarching themes. Monopolisation of life describes the all-encompassing impact diabetes could have on parents due to the constant worry they experienced and the perceived need for vigilance. It describes how parents’ caring responsibilities could affect their wellbeing, relationships and finances, and how a lack of trusted sources of childcare and a desire to enable a ‘normal’ childhood constrained personal choices and activities. However, use of diabetes technologies could lessen some of these burdens. Experiences of professional and informal support describes how encounters with healthcare professionals, while generally perceived as helpful, could lead to frustration and anxiety, and how connecting with other parents caring for a child with type 1 diabetes provided valued emotional and practical support. Conclusions: This synthesis outlines the challenges parents encounter, their views about support received and ways in which support might be improved. It also highlights significant limitations in the current literature and points to important areas for future research, including how sociodemographic factors and use of newer diabetes technologies influence parents’ diabetes management practices and experiences.

(Re)framing a philosophical and epistemological framework for teaching and learning in STEM: Emerging pedagogies for complexity
Today’s learners are engaging in study where access to knowledge is easier than it ever has been in human history. Rapid advancement of technology and the increasing ease with which communication and interaction can occur has dramatically changed the landscape in which teachers of science, technology, engineering and mathematics (STEM) operate. The contemporary skills that students are required to possess include inter alia problem solving, creativity, teamwork abilities, communication skills and emotional intelligence. Despite the universal acceptance of their importance, these skills are commonly cited as underdeveloped and in addition, are still accompanied by outmoded ‘traditional’ forms of teaching and assessment. While the approaches of twentieth-century education were successful in developing knowledge stores, the ubiquity of access to knowledge—coupled with the constantly changing nature of the world today—requires alternative conceptions of teaching and learning. This article focuses primarily on an exploration of learning metaphors and teaching with the overall lens of creating self-regulated and furthermore, self-determined learners. The article begins with an exploration of learning in STEM education and a critique of the pedagogical perspective, discussing why this epistemology may be insufficient for contemporary STEM learning. The article then considers an alternative and potentially more contemporary notion; the emergent pedagogic space. The article presents a theoretical model to conceptualise learning in STEM education, with the goal of informing both practice and research. The realisation of this proposed emergent pedagogical space is explored through an applied case study from a design and technology context
