Enhancing the Reflective Capabilities of Professional Design Practitioners

According to Schon (1987), professional education should be centred on enhancing the practitioner’s ability to reflect before taking action. This is important to the designer for two reasons. The first of these concerns real world professional situations, which are rarely clear and lack ‘right answers’, the successful professional requires the ability to learn by doing in order to handle complex and unpredictable problems with confidence. The second concerns the nature of the designer’s relationship with design problems themselves. The designer’s exploration of his/her own awareness develops in parallel with problem definition. Dorst and Cross (2001) describe this as a co-evolution of problem and solution and English (2006) argues that we cannot frame the problem without including in that design space the person who designs. Thus the process of engaging with a design problem involves a journey of self-exploration for the designer who needs to be appropriately equipped for unknown terrain. A distance learning Masters programme was validated in 1999, supporting professional designers to develop as reflective practitioners. The course has run successfully for eight years with students based in Brazil, Canada, UK and Ireland, Holland, Greece, Arab Emirates, Malaysia, Thailand, Hong Kong and China. The author draws on the experience of delivering this programme to describe two approaches that have evolved in parallel to nurture the development of the reflective practitioner. The first of these encourages students to develop an action research process by applying reflective practice models as organising tools and recording templates. The second clarifies direction and focuses action to address fully and precisely the individual student’s aims, insights and motivation. Both these approaches encourage a synergy between practice and theory and involve visual modelling and collaborative reflection through communities of practice. The application of these approaches is shown to generate fundamental insights that positively influence the future actions of students in professional practice. The paper concludes that the consciousness of the expert designer is a critical element of design space and summarises how the disciplined process and clear focus of the approaches discussed contribute to the development of personal confidence and awareness.

A Mid-Infrared Galaxy Atlas (MIGA)

A mid-infrared atlas of part of the Galactic plane ($75^\circ < l < 148^\circ, b = \pm6^\circ$) has been constructed using HIRES processed infrared data to provide a mid-infrared data set for the Canadian Galactic Plane Survey (CGPS). The addition of this data set to the CGPS will enable the study of the emission from the smallest components of interstellar dust at an angular resolution comparable to that of the radio, millimetre, and far-infrared data in the CGPS. The Mid-Infrared Galaxy Atlas (MIGA) is a mid-infrared (12 $\mu$m and 25 $\mu$m) counterpart to the far-infrared IRAS Galaxy Atlas (IGA), and consists of resolution enhanced ($\sim 0.5'$ resolution) HIRES images along with ancillary maps. This paper describes the processing and characteristics of the atlas, the cross-beam simulation technique used to obtain high-resolution ratio maps, and future plans to extend both the IGA and MIGA.Comment: 38 pages (including 15 tables), 13 figures (8 dithered GIF and 5 EPS).

Image-Processing Techniques for the Creation of Presentation-Quality Astronomical Images

The quality of modern astronomical data, the power of modern computers and the agility of current image-processing software enable the creation of high-quality images in a purely digital form. The combination of these technological advancements has created a new ability to make color astronomical images. And in many ways it has led to a new philosophy towards how to create them. A practical guide is presented on how to generate astronomical images from research data with powerful image-processing programs. These programs use a layering metaphor that allows for an unlimited number of astronomical datasets to be combined in any desired color scheme, creating an immense parameter space to be explored using an iterative approach. Several examples of image creation are presented. A philosophy is also presented on how to use color and composition to create images that simultaneously highlight scientific detail and are aesthetically appealing. This philosophy is necessary because most datasets do not correspond to the wavelength range of sensitivity of the human eye. The use of visual grammar, defined as the elements which affect the interpretation of an image, can maximize the richness and detail in an image while maintaining scientific accuracy. By properly using visual grammar, one can imply qualities that a two-dimensional image intrinsically cannot show, such as depth, motion and energy. In addition, composition can be used to engage viewers and keep them interested for a longer period of time. The use of these techniques can result in a striking image that will effectively convey the science within the image, to scientists and to the public.Comment: 104 pages, 38 figures, submitted to A

Numerical modelling of the lobes of radio galaxies in cluster environments -- IV. Remnant radio galaxies

© 2019 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society.We examine the remnant phase of radio galaxies using three-dimensional hydrodynamical simulations of relativistic jets propagating through cluster environments. By switching the jets off once the lobes have reached a certain length we can study how the energy distribution between the lobes and shocked intra-cluster medium compares to that of an active source, as well as calculate synchrotron emission properties of the remnant sources. We see that as a result of disturbed cluster gas beginning to settle back into the initial cluster potential, streams of dense gas are pushed along the jet axis behind the remnant lobes, causing them to rise out of the cluster faster than they would due to buoyancy. This leads to increased adiabatic losses and a rapid dimming. The rapid decay of total flux density and surface brightness may explain the small number of remnant sources found in samples with a high flux density limit and may cause analytic models to overestimate the remnant fraction expected in sensitive surveys such as those now being carried out with LOFAR.Peer reviewedFinal Accepted Versio

The Change Process and the Implementation of High School Jostens Renaissance Programs: A Multiple Case Study

Motivated by the growing body of research relating to the impact school climate has on student achievement, attendance, behavior, and mental well-being, many educators have implemented initiatives and programs aimed at school climate improvement. Jostens Renaissance is one such program and was the program of focus for this study. Though Jostens has numerous publications and media sources to facilitate the sharing of ideas, there is very little information available regarding the implementation of Renaissance. The primary purpose of this study was to identify factors that facilitated change in the process of implementing high school Jostens Renaissance programs in order to identify any common factors that may be transferable to other schools. A multiple case study approach was utilized to explore the strategies which facilitated the implementation of Renaissance at three southeastern high schools. Data were collected via qualitative interviews with teachers and administrators who were present at their respective schools prior to, during, and after the implementation of Jostens Renaissance. The three study schools selected for the study were identified by Jostens as having strong Renaissance programs. Seven main themes related to change factors were identified: need for change, supportive administration, dedicated faculty coordinator, student leadership and participation, faculty buy-in and participation, intentionality in building teacher climate, and perceived quality of the program. Surprisingly, none of the schools experienced any major barriers the implementation. Participants credited the lack of implementation barriers to a perceived need for change among the school community

Point-of-care measurement of blood lactate in children admitted with febrile illness to an African District Hospital.

BACKGROUND: Lactic acidosis is a consistent predictor of mortality owing to severe infectious disease, but its detection in low-income settings is limited to the clinical sign of "deep breathing" because of the lack of accessible technology for its measurement. We evaluated the use of a point-of-care (POC) diagnostic device for blood lactate measurement to assess the severity of illness in children admitted to a district hospital in Tanzania. METHODS: Children between the ages of 2 months and 13 years with a history of fever were enrolled in the study during a period of 1 year. A full clinical history and examination were undertaken, and blood was collected for culture, microscopy, complete blood cell count, and POC measurement of blood lactate and glucose. RESULTS: The study included 3248 children, of whom 164 (5.0%) died; 45 (27.4%) of these had raised levels of blood lactate (>5 mmol/L) but no deep breathing. Compared with mortality in children with lactate levels of ≤ 3 mmol/L, the unadjusted odds of dying were 1.6 (95% confidence interval [CI].8-3.0), 3.4 (95% CI, 1.5-7.5), and 8.9 (95% CI, 4.7-16.8) in children with blood lactate levels of 3.1-5.0, 5.1-8.0, or >8.0 mmol/L, respectively. The prevalence of raised lactate levels (>5 mmol/L) was greater in children with malaria than in children with nonmalarial febrile illness (P < .001) although the associated mortality was greater in slide-negative children. CONCLUSIONS: POC lactate measurement can contribute to the assessment of children admitted to hospital with febrile illness and can also create an opportunity for more hospitals in resource-poor settings to participate in clinical trials of interventions to reduce mortality associated with hyperlactatemia
