Intervention for learning : supporting school improvement.

Bringing about school improvement has become a national focus for education. There has been little research into school improvement from the perspective of intervention, yet it has become an urgent issue due to the commitment to address under-performance in schools. This research provides insights into the use of research findings about school improvement and effectiveness in working with schools; and insights about how best to support schools in promoting a culture and ways of working in which development can be secured. It uses the development of two projects, in the first phase gaining insights from intervention with eight schools, and in the second phase gaining a closer look at the impact of interventions in two schools at the different levels of headteacher, deputy, subject leader, class teacher and children. The sample draws on schools from different contexts. In the first phase, schools were considered where intervention was welcomed, and the second phase included schools with more embedded difficulties and where intervention had not been sought. The interaction between the impact of intervention at school, classroom and pupil level is explored, drawing out the inter-relationship between the elements of intervention in promoting improvement. The research drew upon a phenomenological perspective to consider the perceptions of those involved in terms of the interventions; methods of data collection were developed which drew upon both qualitative and quantitative processes, including narrative analysis. A model for intervention is offered alongside the identification of the activities and skills of interveners working to promote school improvement. Aspects of change are identified in relation to the technical, cultural and micro-political development. A new identification of the phases of development is given, and aligned to the inter-related aspects of the change process. Turbulence and uncertainty had to be managed constructively as schools moved to the awareness that the skills of rigorous self-evaluation were a key lever for their improvement. Identification of the intervention which supports aspects of change and is phased for different stages of improvement is a recommended way forward

Combine Gathering Attachments for Lodged Corn

Wind damage or stalk rots can cause lodged corn that is difficult to gather with standard corn harvesting equipment. Powered attachments for corn heads are available to assist the gathering process and reduce the number of missed stalks and ears. These attachments assist the flow of corn stalks up and over the snouts and into the gathering chains and cross augers. While required travel speed may still be significantly reduced from normal, these attachments can greatly reduce head plugging and field gathering losses. This article will discuss several combine head attachments to assist in gathering lodged corn and has resources for finding these attachments

Theorising the value of collage in exploring educational leadership

This article contributes to theorising the value of collage as a methodological approach. It begins with a discussion of the methodological difficulties of exploring hidden meanings and individual experience through the research process. The illuminative potential of arts-based methodologies in qualitative research is then investigated. The article makes the case for the specific advantages of using collage to explore the experience of leadership, through a discussion of two collage-based studies. It proposes a variant of the ‘think aloud’ process, used in conjunction with collage, as a route to producing deep understandings of the multiple ways in which leadership is experienced and understood as a social process. The argument is made that collage enables the accessing and sharing of profound levels of experience not accessible through words alone, and considers the impact of the physicality of collage on its potential to release these profound insights. A five-stage process for the analysis of collage is then set out. The article concludes by offering a theory of the value of collage as a methodological approach to exploring experiences of leadership, through use of the concepts of physicality, wholeness and participant agency.Peer reviewe

Ultrafast Electric Field-induced Phase Transition in Bulk Bi0.5Na0.5TiO3 under High Intensity Terahertz Irradiation

“This document is the Accepted Manuscript version of a Published Work that appeared in final form in ACS Photonics, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see https://pubs.acs.org/doi/10.1021/acsphotonics.0c01559”Ultrafast polarization switching is being considered for the next generation of ferroelectric based devices. Recently, the dynamics of the field-induced transitions associated with this switching have been difficult to explore, due to technological limitations. The advent of terahertz (THz) technology has now allowed for the study of these dynamic processes on the picosecond (ps) scale. In this paper, intense terahertz (THz) pulses were used as a high-frequency electric field to investigate ultrafast switching in the relaxor ferroelectric, Bi0.5Na0.5TiO3. Transient atomic-scale responses, which were evident as changes in reflectivity, were captured by THz probing. The high energy THz pulses induce an increase in reflectivity, associated with an ultrafast field-induced phase transition from a weakly polar phase (Cc) to a strongly polar phase (R3c) within 20 ps at 200 K. This phase transition was confirmed using X-ray powder diffraction and by electrical measurements which showed a decrease in the frequency dispersion of relative permittivity at low frequencies

Students' Perception of the Psycho-Social Clinical Learning Environment: An Evaluation of Placement Models

Nursing is a practice based discipline. A supportive environment has been identified as important for the transfer of learning in the clinical context. The aim of the paper was to assess undergraduate nurses' perceptions of the psychosocial characteristics of clinical learning environments within three different clinical placement models. Three hundred and eight-nine undergraduate nursing students rated their perceptions of the psycho-social learning environment using a Clinical Learning Environment Inventory. There were 16 respondents in the Preceptor model category, 269 respondents in the Facilitation model category and 114 respondents in the clinical education unit model across 25 different clinical areas in one tertiary facility. The most positive social climate was associated with the preceptor model. On all subscales the median score was rated higher than the two other models. When clinical education units were compared with the standard facilitation model the median score was rated higher in all of the subscales in the Clinical Learning Environment Inventory. These results suggest that while preceptoring is an effective clinical placement strategy that provides psycho-social support for students, clinical education units that are more sustainable through their placement of greater numbers of students, can provide greater psycho-social support for students than traditional models

Supporting student nurses in practice with additional online communication tools.

Student nurses' potential isolation and difficulties of learning on placement have been well documented and, despite attempts to make placement learning more effective, evidence indicates the continuing schism between formal learning at university and situated learning on placement. First year student nurses, entering placement for the first time, are particularly vulnerable to the vagaries of practice. During 2012 two first year student nurse seminar groups (52 students) were voluntarily recruited for a mixed method study to determine the usage of additional online communication support mechanisms (Facebook, wiki, an email group and traditional methods of support using individual email or phone) while undertaking their first five week clinical placement. The study explores the possibility of strengthening clinical learning and support by promoting the use of Web 2.0 support groups for student nurses. Results indicate a high level of interactivity in both peer and academic support in the use of Facebook and a high level of interactivity in one wiki group. Students' qualitative comments voice an appreciation of being able to access university and peer support whilst working individually on placement. Recommendations from the study challenge universities to use online communication tools already familiar to students to complement the support mechanisms that exist for practice learning. This is tempered by recognition of the responsibility of academics to ensure their students are aware of safe and effective online communication

Non-traumatic Arm, Neck, and Shoulder Complaints in General Practice: Incidence, Course and Management

Non-traumatic complaints of arm, neck, and shoulder are common and can result in functional limitations in daily life and may sometimes lead to sickness absence. Reported symptoms are e.g. pain, tingling, stiffness, numbness, loss of hand coordination. When seeking medical care for these complaints, the general practitioner (GP) is usually the first person to consult. This thesis studies patients who consult their GP with a new non-traumatic complaint of arm, neck or shoulder, with a focus on incidence, course and management. The incidence study showed that a fulltime GP is consulted about 3 times every week for a new non-traumatic complaint of arm, neck, or shoulder, most frequently located at neck or shoulder. Six months after the first consultation with their GP, 46% of the patients in the cohort study reported no recovery. Next to several complaint specific variables, the psychosocial variables little social support and high score on somatization were predicitve of non-recovery at 6 months. Management upto 6 months after the first consultation most frequently consisted of prescribed analgesics and referral for physiotherapy. Specific and non-specific diagnostic subgroups differed in the frequency that corticosteroid injections were applied, and referrals to physiotherapy and to a medical specialist. In addition variables associated with five common management options within a few weeks after the first consultation were evaluated. Overall, besides diagnosis, most frequently long duration of complaints, more functional limitations but also several GP characteristics were associated with the application of a treatment option in non-traumatic arm, neck and shoulder complaints
